Fig. 1 shows a schematic structural view of a heating stove 10 in an embodiment of the present application.

Referring to fig. 1, a heating stove 10 according to an embodiment of the present application includes a heating stove body 110, a bathroom heat exchanger 120, a water tank 130, a bathroom water outlet pipe 140 communicated with the water tank 130, and a water inlet pipe 150 connected to a side of the bathroom heat exchanger 120 away from the water tank 130.

The heating stove body 110 has a heating outlet pipe 111, and hot water produced by the heating stove body 110 flows out from the heating outlet pipe 111. Specifically, the heating stove body 110 further includes a heating water return pipe 112 connected to the water inlet pipe 150, a heating heat exchanger 115, and a combustion mechanism 116, one end of the heating water return pipe 112 remote from the water inlet pipe 150 is connected to the heating water outlet pipe 111, and the water source supplies cold water to the heating water return pipe 112 via the water inlet pipe 150. The high-temperature flue gas generated by the combustion of the combustion mechanism 116 passes through the heating heat exchanger 115 and exchanges heat with the cold water flowing from the water inlet pipe 150 to the heating water return pipe 112, so that the cold water is heated, and the obtained hot water flows out from the heating water outlet pipe 111.

The heating water outlet pipe 111 includes a heating branch pipe 113 and a bathroom branch pipe 114 connected to the bathroom heat exchanger 120, and the hot water flowing out of the heating water outlet pipe 111 may flow into the heating branch pipe 113 and/or the bathroom branch pipe 114, respectively.

The bathroom heat exchanger 120 is connected to the water tank 130 through a pipeline, the water inlet pipe 150 is connected to one side of the bathroom heat exchanger 120 away from the water tank 130, and the bathroom water outlet pipe 140 is communicated with the water tank 130, so that the cold water flowing out of the water inlet pipe 150 flows through the bathroom heat exchanger 120 and further flows to the water tank 130 and the bathroom water outlet pipe 140, and the hot water flowing into the bathroom branch pipeline 114 can exchange heat with the fluid flowing from the water inlet pipe 150 to the bathroom water outlet pipe 140 by means of the bathroom heat exchanger 120. When the heating stove 10 operates in the heating bathroom mode, the cold water flowing from the water inlet pipe 150 to the bathroom water outlet pipe 140 flows through the bathroom heat exchanger 120, and can exchange heat with the hot water flowing from the bathroom branch pipe 114 to the bathroom heat exchanger 120, so that the cold water flowing from the water inlet pipe 150 to the bathroom water outlet pipe 140 is heated, and the heated hot water can flow out from the bathroom water outlet pipe 140, and can be used in the bathroom of the user. In addition, the fluid flowing from the sanitary heat exchanger 120 to the sanitary outlet pipe 140 may exchange heat with the water in the water tank 130.

Alternatively, a heating circulation pump 1121 is disposed on the heating water return pipe 112, the heating water outlet pipe 111, and the bathroom branch pipes 114 are connected to form a heating circulation pipe, and water in the heating circulation pipe circulates and flows under the driving of the heating circulation pump 1121.

Optionally, the heating stove 10 further includes a bathroom return pipe 1401 connected to the bathroom outlet pipe 140, and one end of the bathroom return pipe 1401 far away from the bathroom outlet pipe 140 is connected to the inlet pipe 150, so that the inlet pipe 150, the bathroom heat exchanger 120, the bathroom outlet pipe 140, and the bathroom return pipe 1401 are connected to form a bathroom circulation pipeline. The hot water flowing out of the bathroom water outlet pipe 140 flows into the water inlet pipe 150 through the bathroom water return pipe 1401 and flows to the bathroom heat exchanger 120 and the bathroom water outlet pipe 140 again, which is favorable for the water temperature of the bathroom water outlet pipe 140 to reach the target outlet water temperature T of the bathroom water outlet pipe 140 quickly₀。

Optionally, a bathroom circulating pump 1402 is disposed on the bathroom water return pipe 1401, and water in the bathroom circulating pipe circulates and flows under the driving of the bathroom circulating pump 1402.

Fig. 2 is a flow chart showing a control method of the heating stove 10 in an embodiment of the present application.

Referring to fig. 2, the control method of the heating stove 10 includes the steps of:

causing the heating stove 10 to start.

S410, under the condition that the heating stove 10 is in the heating bathroom mode, whether the actual water temperature of the bathroom water outlet pipe 140 is larger than or equal to a first preset temperature T or not is judged₁。

When the heating stove 10 is in the heating bathroom mode, the heating water outlet pipe 111 is communicated with the bathroom branch pipes 114. The fluid flowing out of the water inlet pipe 150 flows to the bathroom heat exchanger 120 and the bathroom water outlet pipe 140 in sequence, and the fluid flowing out of the heating water outlet pipe 111 flows to the bathroom branch pipes 114. The cold water flowing from the water inlet pipe 150 to the bathroom heat exchanger 120 and the bathroom water outlet pipe 140 is heated by the hot water flowing from the heating water outlet pipe 111, that is, the cold water flowing from the water inlet pipe 150 to the bathroom water outlet pipe 140 can be heated by the hot water prepared by the heating furnace body 110 when the heating furnace 10 is in the heating bathroom mode.

S420, if the actual water temperature of the bathroom water outlet pipe 140 is greater than or equal to the first preset temperature T₁And stopping the heating bathroom mode. A first preset temperature T₁Equivalent to the target outlet water temperature T of the outlet pipe 140 of the bathroom₀。

S422, the heating stove 10 is controlled to be switched from the heating bathroom mode to the water tank heat preservation mode, so that the actual water temperature of the bathroom water outlet pipe 140 is not less than a second preset temperature T₂Wherein the second preset temperature T₂Greater than or equal to a first preset temperature T₁. By using the heating bathroom mode, the actual water temperature of the bathroom water outlet pipe 140 can be heated to the target water outlet temperature T of the bathroom water outlet pipe 140₀Stopping the heating bathroom mode, and maintaining the actual water temperature of the bathroom water outlet pipe 140 at a first preset temperature T or higher by means of the water tank heat preservation mode₁Second predetermined temperature T₂That is, the water in the bathroom outlet pipe 140 is preheated in the heating bathroom mode, and the water in the bathroom outlet pipe 140 is insulated in the water tank insulation mode, so that the operation time of the heating bathroom mode can be reduced, the frequent switching between the heating bathroom mode and the single heating mode due to the insulation of the bathroom outlet pipe 140 during the heating of the heating stove 10 can be avoided, and the influence on the heating of the user can be reduced.

It should be noted that, when the heating stove 10 is in the water tank heat preservation mode, the heating outlet pipe 111 is linked together with the heating branch pipeline 113, and the heating outlet pipe 111 is not linked together with the bathroom branch pipeline 114, so, the fluid that the heating outlet pipe 111 flows out only flows to the heating branch pipeline 113, and the heating stove 10 is still in the single heating mode, can satisfy heating demand and bathroom demand simultaneously under the condition of not influencing each other, reduces the influence to user's heating better. Specifically, when the heating stove 10 is in the water tank heat preservation mode, the fluid flowing out of the water inlet pipe 150 flows to the bathroom heat exchanger 120 and the bathroom water outlet pipe 140 in sequence, and the fluid flowing out of the heating water outlet pipe 111 flows to the heating branch pipe 113. The actual water temperature of the bathroom water outlet pipe 140 is not less than the second preset temperature T by using the water tank heat preservation mode₂To ensure the actual water temperature of the bathroom outlet pipe 140 and the bathroom return pipe 1401And the water in the water tank 130 is in a heat-preserving state.

Optionally, the first preset temperature T₁Equal to the target outlet water temperature T of the bathroom outlet pipe 140₀The second predetermined temperature T may be set in consideration of heat loss in the pipe₂Is greater than the target outlet water temperature T of the bathroom outlet pipe 140₀。

In particular, a first preset temperature T₁Is equal to T₀Second predetermined temperature T₂Is equal to T₀+3。

Further, the heating water outlet pipe 111 further includes a heating bathroom switching valve 1111, and the heating bathroom switching valve 1111 is disposed at a connection position of the heating branch pipe 113 and the bathroom branch pipe 114. The heating bath switching valve 1111 may be controlled to switch to the heating water outlet pipe 111 to communicate with the bath branch pipe 114 so that the heating stove 10 operates the heating bath mode. The heating bath switching valve 1111 may also be controlled by the control device to switch to the heating water outlet pipe 111 to communicate with the heating branch pipe 113, so that the heating stove 10 operates the water tank heat preservation mode and the single heating mode.

Further, please refer to fig. 2 again, the heating stove 10 is controlled to switch from the heating bathroom mode to the water tank heat preservation mode, so that the actual water temperature of the bathroom water outlet pipe 140 is not less than the second preset temperature T₂After S420, the control method of the heating stove 10 further includes:

s430, judging whether the actual water temperature of the bathroom water outlet pipe 140 is less than or equal to a third preset temperature T₃。

S440, if the actual water temperature of the bathroom water outlet pipe 140 is less than or equal to the third preset temperature T₃Then, the heating stove 10 is controlled to be switched from the water tank heat preservation mode to the heating bathroom mode, wherein the third preset temperature T₃Less than a first predetermined temperature T₁. In the process of operating the water tank heat preservation mode of the heating stove 10, since the hot water pipes of the users have different lengths and different heat preservation effects (wherein the hot water pipes include the bathroom outlet pipe 140 and the bathroom return pipe 1401, etc.), the heat dissipation speed of the hot water pipes of the users is fast or slow, and thus, in the water tank heat preservation mode, when necessary, the users can perform the heat preservation modeThe temperature of the hot water pipeline is monitored. At this time, the actual water temperature of the bathroom outlet pipe 140 is less than or equal to the third preset temperature T₃And a third predetermined temperature T₃Less than a first predetermined temperature T₁If the first preset temperature T₁Is equal to T₀Then, it means that the actual water temperature of the bathroom outlet pipe 140 is low, and it is preferable to select the heating bathroom mode to heat the cold water flowing from the inlet pipe 150 to the bathroom outlet pipe 140, because: in some embodiments, in order not to affect the household power grid, the water tank heat preservation mode is usually heated by means of the heating element 133, the power of the heating element 133 is usually small, if the heat dissipation speed of the hot water pipeline of the user is large, then, in the water tank heat preservation mode, the heating element 133 is used for heating, the heat dissipation of the hot water pipeline cannot be compensated, further, the temperature of the hot water pipeline can be continuously reduced, at this time, the heating element 133 is not suitable for being used for heating, and the water tank heat preservation mode is switched to a heating bathroom mode, which is more suitable.

Optionally, a third preset temperature T₃＝T₀-5。

Further, please refer to fig. 2 again, if the actual water temperature of the bathroom outlet pipe 140 is less than or equal to the third preset temperature T₃After the step S440 of controlling the heating stove 10 to switch from the water tank heat preservation mode to the heating bathroom mode, the control method of the heating stove 10 further includes:

returning to execute the operation of judging whether the actual water temperature of the bathroom water outlet pipe 140 is greater than or equal to the first preset temperature T or not when the heating stove 10 is in the bathroom water using mode and in the heating bathroom mode₁Step S410. So that when the actual water temperature of the bathroom water outlet pipe 140 is greater than or equal to the first preset temperature T during the heating bathroom mode₁And the heating bathroom mode can be switched to the water tank heat preservation mode, so that the running time of the heating bathroom mode is further reduced, the influence on the heating of users caused by the heating bathroom mode is reduced, and the flexibility of the control method is improved.

Further, please refer to fig. 2 again, when the heating stove 10 is in the bathroom water mode and the heating bathroom mode, it is determined whether the actual water temperature of the bathroom water outlet pipe 140 is greater than or equal to the actual water temperature of the bathroom water outlet pipe 140A first preset temperature T₁Before step S410, the method for controlling the heating stove 10 further includes:

further, under the condition that the heating stove 10 is in the heating bathroom mode, it is determined whether the actual water temperature of the bathroom water outlet pipe 140 is greater than or equal to the first preset temperature T₁Before step S410, the method for controlling the heating stove 10 further includes:

s400, controlling the heating stove 10 to operate in a water tank heat preservation mode. After heating stove 10 starts, can make heating stove 10 running water tank heat preservation mode before the user uses the bathroom water, and then make bathroom outlet pipe 140's actual temperature not less than the second and predetermine temperature T₂. The water in the water tank 130 can be heated under the condition of off-peak power utilization, and the water temperature in the water tank 130 is approximately consistent with the water temperature of the bathroom water outlet pipe 140 and tends to be in a constant temperature state, so that the effect of instant heating and instant heating can be achieved when a user uses bathroom water in a power utilization peak period. In addition, before the user uses the bathroom water, the actual water temperature of the bathroom water outlet pipe 140 is greater than or equal to the second preset temperature T₂And a second predetermined temperature T₂Greater than or equal to a first preset temperature T₁The time for preheating by using the heating bathroom mode can be further reduced, and the influence on the heating of users can be further reduced.

Optionally, in the process of preheating in the heating bathroom mode, water in the bathroom circulation pipeline may be circulated by the bathroom circulation pump 1402, so as to improve the preheating efficiency. The water in the bathroom circulating pipeline can be circulated and flowed under the heat preservation mode of the water tank, so that the heat preservation efficiency is improved, the water in the bathroom circulating pipeline is circulated under the driving of the bathroom circulating pump 1402, and finally the water temperature in the bathroom circulating pipeline is consistent with the water temperature in the water tank 130, thereby being more beneficial to quickly enabling the actual water temperature of the bathroom water outlet pipe 140 to be more than or equal to the second preset temperature T₂。

Optionally, the heating stove 10 is operated in the tank warming mode in case of off-peak electricity utilization to heat the water in the tank 130 such that the water temperature in the tank 130 and the water temperature of the bathroom outlet pipe 140 are substantially at the second preset temperature T₂And tends to a constant temperature state, so that the user uses electricityWhen the bathroom water is used in the peak period, the effect of heating immediately after opening can be achieved.

S401, judging whether the heating stove 10 is in a bathroom water using mode for the first time.

If the heating stove 10 is in the bathroom water mode, it indicates that the user starts using the bathroom water, that is, the cold water flowing out of the water inlet pipe 150 flows to the bathroom heat exchanger 120 and the bathroom water outlet pipe 140 in sequence.

Optionally, the bathroom water mode includes a bathroom circulation mode, wherein when the heating stove 10 is in the bathroom circulation mode, the bathroom circulation pump 1402 operates, and water in the bathroom circulation pipe circulates and flows.

Alternatively, the bathroom water mode of the heating stove 10 may be triggered and started when the user uses the bathroom water, the bathroom water mode of the heating stove 10 may also be started by means of a bathroom button of the heating stove 10, and the bathroom water mode of the heating stove 10 may also be started through a client connected with the heating stove 10 in wireless communication.

And S403, if the heating stove 10 is in the bathroom water use mode for the first time, controlling the heating stove 10 to be switched to the heating bathroom mode from the water tank heat preservation mode. After heating stove 10 starts, if heating stove 10 is in bathroom water consumption mode for the first time, then explain that heating bathroom mode is not opened after heating stove 10 opens, rely on water tank heat preservation mode alone, probably can not satisfy user's bathroom demand, unsuitable water tank heat preservation mode that adopts at this moment heats, more be fit for heating with the help of heating bathroom mode to make bathroom outlet pipe 140's actual temperature can reach first predetermined temperature T₁Further, the actual temperature of the bathroom outlet pipe 140 can reach the target outlet temperature, and then the heat is preserved by means of the water tank heat preservation mode, so that the bathroom water demand can be met.

Further, referring again to fig. 2, the control method of the heating stove 10 further includes:

if the heating stove 10 is not in the bathroom water usage mode for the first time, it is determined whether the operation time of the bathroom water usage mode satisfies the first condition and the actual water temperature of the bathroom water outlet pipe 140 satisfies the second condition.

If the first condition and the second condition are satisfied, step S403 of controlling the heating stove 10 to switch from the tank insulation mode to the heating bathroom mode is performed.

Wherein, the first condition is that the running time of the bathroom water mode is greater than the bathroom water critical time t₁The second condition is that the actual water temperature of the bathroom outlet pipe 140 is less than or equal to the lower temperature limit of the thermal insulation. The lower limit temperature of the heat preservation is less than the third preset temperature T₃. According to the critical time t of water for bathroom₁And judging whether the user uses the bathroom water for a short time. The heat-retaining lower limit temperature is a lower limit temperature of the heat-retaining mode of the operation tank of the heating stove 10, and thus, whether the heat-retaining mode of the operation tank of the heating stove 10 is required to be switched to another mode or not is judged under the condition that the heating stove is not in the bathroom water use mode for the first time. At this time, the operation time of the bathroom water mode is greater than the bathroom water critical time t₁And the actual water temperature of the bathroom outlet pipe 140 is less than or equal to the lower temperature limit of the heat preservation, it indicates that the user starts to use the bathroom water for a long time, the user has a possibility of bathing, and the actual water temperature of the bathroom outlet pipe 140 is lower than the third preset temperature, which also indicates that the water tank heat preservation mode can no longer meet the bathroom requirements of the user at this time, so the heating mode by the heating element 133 is not suitable, and the heating bathroom mode is more suitable for use, for example, the heating mode is performed by means of the combustion mechanism 116 of the heating stove body 110, the heating heat exchanger 115, the bathroom heat exchanger 120, and the like.

Optionally, the lower limit temperature of the heat preservation is T₀-10。

Optionally, critical time t for bathroom water₁0.5-2 minutes.

Further, referring again to fig. 2, the control method of the heating stove 10 further includes: if the first condition and/or the second condition are/is not met, the heating stove 10 is controlled to maintain the operation water tank heat preservation mode, so that the actual water temperature of the bathroom water outlet pipe 140 is not less than the second preset temperature T₂Step S422.

If the first condition is not met, the running time of the bathroom water mode is less than or equal to the bathroom water critical time t₁That is, it indicates that the user is only using the bath water for a short time and there may be practically no washingThe heating stove 10 can be operated in a water tank heat preservation mode according to the bath requirement.

If the second condition is not satisfied, it indicates that the actual water temperature of the bathroom outlet pipe 140 is greater than the lower limit temperature of heat preservation, that is, the water temperature in the water tank 130 is not low, and after the bathroom water usage mode, because the heating stove 10 is not in the bathroom water usage mode for the first time, it indicates that the bathroom mode of heating has been used, the water temperature of the water tank 130 is very high, even possible heating stove 10 is still in the water tank heat preservation mode, the actual water temperature of the bathroom outlet pipe 140 is high, then, utilize the heating member 133 to continue heating, be enough to satisfy the bathroom requirement of the user, also can make the heating stove 10 operate the water tank heat preservation mode.

The running time of the bathroom water using mode is less than or equal to the bathroom water using critical time t₁And when the actual water temperature of the bathroom outlet pipe 140 is greater than the heat preservation lower limit temperature and at least one of the first condition and the second condition is not satisfied, the heating stove 10 can be operated in the water tank heat preservation mode. And by means of the two conditions, the heating stove 10 can select the water tank heat preservation mode preferentially, the running time of the heating bathroom mode is reduced, and the influence on the heating of users is also reduced.

Further, the number of the water tanks 130 is two, and a heating member 133 for heating the liquid in the water tank 130 may be provided on each water tank 130.

So that the actual water temperature of the bathroom outlet pipe 140 is not less than the second preset temperature T₂The method is realized by adopting the following steps:

heating the liquid in one 130 of the two water tanks 130, if the actual water temperature of the bathroom water outlet pipe 140 is less than the second predetermined temperature T after the predetermined time interval₂Then, the liquid in the other water tank 130 of the two water tanks is heated until the actual water temperature of the bathroom water outlet pipe 140 is not less than the second preset temperature T₂. The water in the corresponding water tank 130 can be heated by the heating element 133, the two water tanks 130 of the water tank assembly are independently controlled, the heating element 133 corresponding to one of the water tanks 130 is started firstly, and after a preset time interval, according to whether the actual water temperature of the bathroom water outlet pipe 140 is less than the second preset temperature T or not₂Judging whether to start the heating corresponding to another water tank 130And a member 133. During this period, if the actual water temperature of the bathroom outlet pipe 140 is greater than or equal to the second preset temperature T₂Then, the heating member 133 is stopped from heating.

In some embodiments, the predetermined time interval is 3-10 minutes.

Further, the heating stove 10 further comprises a control device configured to determine whether the actual water temperature of the bathroom water outlet pipe 140 is greater than or equal to the first preset temperature T under the condition that the heating stove 10 is in the bathroom water mode and in the heating bathroom mode₁(ii) a If yes, the heating stove 10 is controlled to be switched from the heating bathroom mode to the water tank heat preservation mode, so that the actual water temperature of the bathroom water outlet pipe 140 is not less than the second preset temperature T₂。

Optionally, the heating stove 10 further includes a temperature probe disposed on the bathroom outlet pipe 140, and the temperature probe and all the heating members 133 are electrically connected to the control device. The control device heats at least one of the two heating elements 133 according to the actual water temperature of the bathroom water outlet pipe 140 obtained by the temperature probe.

Referring to fig. 3 and 4, the two water tanks 130 are arranged in the first direction to form the water tank assembly arranged side by side at one side of the second direction of the heating stove body 110. Wherein the heating stove body 110 has a front side, and a first side and a second side adjacent to the front side and parallel to each other, the first direction is a direction in which the first side is directed to the second side, and the second direction is perpendicular to the front side of the heating stove body 110. Particularly, in the embodiment shown in fig. 3 and 4, the first direction is a front-rear direction, and the second direction is a left-right direction, so that the water tank assembly and the heating stove body 110 can be compactly arranged.

The orthographic projection of two water tanks 130 in the water tank assembly on the second side surface falls completely into the second side surface, it can be understood that the dimension of the water tank assembly along the first direction is not more than the dimension of the heating stove body 110 along the first direction, then the occupied dimension of the heating stove body 110 and the water tank assembly along the first direction is equal to the dimension of the heating stove body 110 along the first direction, and the occupied dimension of the heating stove body 110 and the water tank assembly along the second direction is approximately equal to the sum of the dimensions of the heating stove body 110 and one water tank 130 along the second direction; the water tank 130 with larger capacity is generally selected under the condition of the same surface area, correspondingly, the water tank 130 is selected as the water tank 130 with a cylindrical structure, so that a single large water tank with a cylindrical structure is taken as a reference object, the volume of the reference object is equal to the total volume of the two water tanks 130, and the height of the reference object is equal to the height of the water tank 130 for comparison reference, the occupied size of the heating stove body 110 and the single large water tank along the first direction is still equal to the size of the heating stove body 110 along the first direction, and the occupied size of the heating stove body 110 and the single large water tank along the second direction is approximately equal to the sum of the sizes of the heating stove body 110 and the single large water tank along the second direction. Obviously, the diameter of the water tank 130 is smaller than that of the single large water tank, and thus, the occupying dimension of the heating stove body 110 and the single large water tank in the second direction is larger than the occupying dimension of the heating stove body 110 and the water tank assembly in the second direction. Therefore, compared with the whole occupied space of a single large water tank and the heating stove body 110, the whole occupied space of the two water tanks 130 and the heating stove body 110 is smaller, the size of the whole machine is favorably reduced, and the installation space of the heating stove 10 can be reduced to the maximum extent.

In some embodiments, the water tanks 130 are cylindrical structures, the diameter of the water tanks 130 is 140mm, and the total water volume of the two water tanks 130 is 18.5L; if a single large water tank with the volume of 18.5L is used as a reference object; in the case where the large tanks and the water tank 130 are the same height, the diameter of the single large tank is about 210 mm. If the heating stove body 110 has a dimension L along the first direction₁The heating stove body 110 has a dimension L in the second direction₂Wherein L is₁Greater than 280mm, then the overall footprint of the two tanks 130 and the heating stove body 110 in the first direction is equal to L₁The overall footprint of the two tanks 130 and the heating stove body 110 in the second direction is substantially equal to L₂+140 mm; and the overall footprint of the single large tank and heating stove body 110 in the first direction is also equal to L₁The overall footprint of the single large tank and heating stove body 110 in the second direction is substantially equal to L₂+210 mm; it is apparent that the overall space occupied by the two water tanks 130 and the heating stove body 110 is smaller.

Further, referring to fig. 1 again in combination with fig. 5, each water tank 130 includes a tank body 131 and a tank heat exchange pipe 132 disposed in the tank body 131, and the water tank 130 is in heat exchange contact with the fluid flowing from the sanitary heat exchanger 120 to the sanitary outlet pipe 140 by means of the tank heat exchange pipe 132. Two ends of the water tank heat exchange tube 132 are respectively communicated with the bathroom heat exchanger 120 and the bathroom water outlet tube 140, specifically, the water tank heat exchange tubes 132 of the two water tanks 130 are connected to each other, and one ends of the water tank heat exchange tubes 132 of the two water tanks 130, which are far away from each other, are respectively connected to the bathroom heat exchanger 120 and the bathroom water outlet tube 140. Cold water flowing from the water inlet pipe 150 to the sanitary heat exchanger 120 exchanges heat with hot water flowing from the sanitary branch pipe 114 to the sanitary heat exchanger 120, flows into the two tank heat exchanging pipes 132 in sequence, exchanges heat with water in the water tank 130, and finally flows to the sanitary water outlet pipe 140. The cold water that can make with the help of heating stove body 110 makes and flows to bathroom outlet pipe 140 by inlet tube 150 heats, and then avoids losing through the hydrothermal heat of water tank heat exchange tube 132 with the help of water tank 130 of taking the heating function, reaches the effect of opening promptly and heat promptly, can improve user experience and feel.

Further, referring again to fig. 5, the tank heat exchanging pipe 132 is constructed to spirally extend from one end of the tank body 131 to the other end of the tank body 131 around the center line of the tank body 131. The contact area between the water tank heat exchange pipe 132 and the water inside the water tank body 131 can be increased, and the heat exchange efficiency between the water inside the water tank heat exchange pipe 132 and the water inside the water tank body 131 can be improved.

Further, referring to fig. 1 again, each of the tank bodies 131 is provided with a heating member 133 for heating the fluid in the corresponding tank body 131, so that two heating members 133 can be heated together, or one of the heating members 133 can be heated, and the number of the heating members 133 to be heated is selected according to actual needs.

Further, referring to fig. 1 again, one end of the heating element 133 is connected to the water tank 130, and the other end extends into the water tank 130, and the heating element 133 is disposed in the water tank 130, so that the overall occupied space of the water tank 130 can be further reduced.

Alternatively, the heating member 133 is a heating coil, and a contact area of the heating member 133 with water in the water tank 130 can be increased, thereby improving heating efficiency and heat preservation effect of the water tank 130.

Alternatively, the heating member 133 is an electric heating member that heats the water in the water tank 130 by electric heating.

It should be noted that, the peak power consumption can be staggered, so that the water in the water tank 130 is heated to a heat preservation state, so as to ensure that the user can be heated when using the bathroom water, and the experience of the bathroom water is improved.

Further, referring to fig. 3 and 4 again, the heating stove 10 further includes a housing 160 (a partial structure of the housing 160 is schematically shown in fig. 3), the heating stove body 110 and the water tank assembly are both located in the housing 160, and the heating stove body 110 and the water tank assembly are installed in the housing 160, so that the overall carrying and the overall installation of the heating stove 10 are facilitated, and the appearance is more beautiful.

In some embodiments, each water tank 130 is provided with a water tank heat exchange pipe 132 and a heating element 133 inside, so that the water tank 130 has the characteristics of small occupied space, large water storage capacity, constant water temperature and the like, the overall size of the heating stove 10 is small, and the installation space of the heating stove 10 can be reduced to the maximum extent.

By means of the water tank heat preservation mode and the bathroom circulating pump 1402, the actual water temperature of the bathroom outlet pipe 140 can be greater than or equal to the target outlet water temperature T₀The heating stove 10 can be prevented from influencing heating due to frequent switching of the heating bathroom mode and the single heating mode during the heating period because the bathroom water outlet pipe 140 is used for heating during the heating period, water in the water tank 130 can be heated to a heat preservation state in the off-peak power utilization time, and the function of instant heating can be better guaranteed.
