The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

A steam box 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 5.

As shown in fig. 1, a steam box 100 according to an embodiment of the present invention includes: a chamber 110 and a steam generator 120. Specifically, a cooking cavity 111 is defined in the cavity 110, and the cooking cavity 111 is used for placing food to be cooked; the steam generator 120 is connected with a water inlet pipe 130 and an air outlet pipe 140, the air outlet end of the air outlet pipe 130 is communicated with the cooking cavity 111, and the steam generator 120 is arranged on the lower side of the bottom wall of the cooking cavity 111 and is suitable for heating the bottom wall of the cooking cavity 111; thereby make steam ager 100 at the in-process of culinary art, steam generator 120 can also get rid of the ponding of culinary art chamber 111 diapire when producing steam and cook to avoid the bacterium of ponding to breed and cause the pollution of environment among the culinary art chamber 111, make the environment in steam ager 100 more sanitary.

According to the steam box 100 provided by the embodiment of the invention, the steam generator 120 is arranged at the lower side of the bottom wall of the cooking cavity 111, so that the steam generator 120 can be used for providing steam for the steam box 100 and heating the bottom wall of the cooking cavity 111, accumulated water on the bottom wall of the cooking cavity 111 can be heated, the accumulated water is prevented from being accumulated in the cooking cavity 111, further the pollution to the environment in the cooking cavity 111 caused by the breeding of bacteria in the accumulated water is avoided, the environment in the steam box 100 is more sanitary, and meanwhile, compared with the related art in which an additional heating element is arranged for removing the accumulated water on the bottom of the cooking cavity, the steam generator 120 for generating steam is directly used for heating the accumulated water on the bottom of the cooking cavity 111, the number of parts in the steam box 100 can be reduced, the cost is reduced, and the utilization rate of heat of the steam generator 120 can be improved.

The shape of the cavity 110 may be determined by the shape of the steam box 100, as shown in fig. 1, the shape of the steam box 100 is a rectangular parallelepiped, and then the shape of the cavity 110 may also be a rectangular parallelepiped, so that the space inside the steam box 100 is fully utilized.

Further, as shown in fig. 2, the steam generator 120 may be a flow channel evaporator, and the flow channel evaporator may include a flow channel evaporator case 121, a heating pipe 123 and a heat exchanging pipe 122, the heat exchanging pipe 122 spirally extends in a direction perpendicular to a horizontal plane inside the flow channel evaporator case 121, one end of the heat exchanging pipe 122 is connected to the water inlet pipe 130, and the other end is connected to the air outlet pipe 140; the heating pipe 123 extends spirally and radially in a zigzag manner along the heat exchange pipe 122, and the heating pipe 123 is disposed at the radial inner side of the heat exchange pipe 122, in other words, the heat exchange pipe 122 is sleeved at the radial outer side of the heating pipe 123. The heating pipe 123 may be a resistance wire, when the heating pipe 123 is powered on, the temperature rises, the heat exchange pipe 122 surrounding the heating pipe 123 can be heated, and when water passes through the steam generator 120, the temperature of the water rises at a very high speed to be vaporized, and the water is converted into steam, and then is conveyed into the cooking cavity 111 through the air outlet pipe 140. The heating pipe 123 needs to be heated continuously throughout the steaming process to maintain the temperature of the steam generator 120 at a fixed preset value.

For example, as shown in fig. 1, the preset temperature value of the steam generator 120 may be set to 200 ℃, 200 ℃ far exceeding the boiling temperature of water, and when water enters the steam generator 120 through the inlet pipe 130, the temperature rises suddenly, so that the water is rapidly vaporized into water vapor, and the water vapor enters the cooking cavity 111 through the outlet pipe 140. Of course, the present invention is not limited thereto, and the preset temperature value of the steam generator 120 may also be set to 180 ℃, 190 ℃, 210 ℃, etc.

Further, the air outlet pipe 130 can be made of a high temperature resistant rubber hose, so that the air outlet pipe 130 is not damaged due to too high temperature, and the normal operation of the steam box 100 is ensured. For example, the high temperature resistant rubber tube can be composed of an inner rubber layer, an outer rubber layer and a framework layer and is used for conveying high temperature gas, liquid and slurry.

Optionally, the air outlet end of the air outlet pipe 130 may be disposed at the top or the bottom of the side wall of the cooking cavity 111, so that the water vapor released from the air outlet end can circulate in the cooking cavity 111, and the water vapor released from the air outlet end is prevented from directly acting on the food, thereby preventing the food from being pinched due to uneven heating after processing.

In one embodiment of the present invention, as shown in fig. 1, an upper surface of the steam generator 120 is attached to a lower surface of a bottom wall of the cooking cavity 111, thereby improving heat utilization efficiency of the steam generator 120.

Wherein, as shown in fig. 1, because the area of the upper surface of the steam generator 120 is smaller than the area of the lower surface of the bottom wall of the cooking cavity 111, in order to make the accumulated water on the bottom wall of the cooking cavity 111 better absorb the heat of the steam generator 120, the bottom wall of the cooking cavity 111 can be inclined downwards from outside to inside, so that the accumulated water generated in the working process of the steam box 100 can slide down to the bottom wall of the cooking cavity 111 through the side wall of the cooking cavity 111, and the accumulated water is collected together, thereby facilitating the steam generator 120 to heat the accumulated water in a centralized manner.

In one embodiment of the present invention, as shown in fig. 1, the steam box 100 may further include a temperature sensor 124, and the temperature sensor 124 is disposed on the steam generator 120 for detecting a surface temperature of the steam generator 120. The temperature sensor 124 is a sensor that converts a temperature variable into a standardized output signal that can be transmitted.

Further, throughout the operation of the steam box 100, the temperature of the steam generator 120 is maintained at a predetermined temperature, and the presence of the temperature sensor 124 enables real-time monitoring of the surface temperature of the steam generator 120 by the steam box 100.

In one embodiment of the present invention, as shown in fig. 3, the steam box 100 may further include a controller 160, and the controller 160 is communicatively connected to the temperature sensor 124 and the steam generator 120. The controller 160 is a master device for controlling the starting, speed regulation, braking and reversing of electrical components by changing the wiring of the control circuit and changing the resistance value in the circuit according to a predetermined sequence.

Specifically, in the embodiment, the controller 160 is communicatively connected to the temperature sensor 124, and when the steam generator 120 is only used for removing the accumulated water in the cooking cavity 111, the controller 160 transmits a signal for stopping heating to the steam generator 120 after the temperature sensor 124 detects that the temperature of the steam generator 120 reaches a preset temperature, thereby avoiding wasting energy.

In one embodiment of the present invention, as shown in FIG. 1, a water pump 150 is connected in series with the water inlet pipe 130, and a controller 160 is communicatively connected to the water pump 150. Wherein, the water pumping amount of the steam generator 120 can be controlled by connecting the controller 160 with the water pump 150, thereby avoiding the waste of water resources.

Specifically, when the controller 160 receives the signal for increasing or decreasing the pumping amount, the controller 160 transmits the signal for increasing or decreasing the pumping amount to the water pump 150, and then the water pump 150 can change the pumping amount by adjusting the rotation speed or power thereof, so that the water entering the steam generator 120 can be replenished according to specific needs, thereby avoiding unnecessary waste of resources.

In one embodiment of the present invention, the water inlet pipe 130 may be serially connected with a solenoid valve, that is, a solenoid valve may be provided at the position of the water pump 150 instead, and the flow rate of water supplied into the steam generator 120 may be adjusted by adjusting the opening degree of the solenoid valve. The electromagnetic valve is a device controlled by electromagnetism, is an automatic basic element for controlling fluid, belongs to an actuator, is not limited to hydraulic pressure and pneumatic pressure, can be matched with different circuits to realize expected control, and can ensure the precision and flexibility of the control.

Specifically, in this embodiment, after the controller 160 receives the signal of increasing or decreasing the pumping amount, the controller 160 transmits a corresponding signal of increasing or decreasing to the solenoid valve, and then the solenoid valve precisely controls the increase or decrease of the pumping amount, so that the water entering the steam generator 120 can be replenished according to specific needs, thereby avoiding unnecessary waste of resources.

In other embodiments, the water inlet pipe can be connected with an electromagnetic valve and a water pump in series, and the adjustment of the water flow introduced into the steam generator can be realized by adjusting the electromagnetic valve and the water pump.

In one embodiment of the present invention, as shown in FIG. 1, the controller 160 is configured to control the amount of water pumped by the water pump 150 to the steam generator 120 based on the temperature value detected by the temperature sensor 124. Thereby achieving the correlation between the surface temperature of the steam generator 120 and the pumping amount of the water pump 150.

Specifically, when there is ponding in culinary art chamber 111, because the specific heat capacity of water is big, the lower surface laminating of the upper surface of steam generator 120 and the diapire of culinary art chamber 111, make the speed of the temperature variation of steam generator 120 upper surface slow down, thermal inertia grow, controller 160 can transmit the signal that reduces the volume of beating water to water pump 150 this moment, water pump 150 reduces the volume of beating water to steam generator 120, in the whole process, steam generator 120 is keeping predetermined temperature throughout and is heating the bottom of culinary art chamber 111, thereby make the ponding of culinary art chamber 111 bottom vaporize once more and form steam, realize the cyclic utilization of ponding, and then reduce the ponding of culinary art chamber 111 bottom, the burden of culinary art chamber 111 later stage clearance has been lightened.

In one embodiment of the present invention, as shown in fig. 1, the bottom wall of the cooking cavity 111 may include a water collecting portion 113 and a flow guide portion 112, the flow guide portion 112 is disposed around the water collecting portion 113, and a circumferential edge of the water collecting portion 113 is connected to a radially inner side edge of the flow guide portion 112, an upper side surface of the flow guide portion 112 is formed as a flow guide surface extending downward in a direction from the circumferential edge of the bottom wall of the cooking cavity 111 toward the water collecting portion 113, and the steam generator 120 is vertically opposite to the water collecting portion 113. Thereby improving the heat utilization efficiency of the steam generator 120 for heating the accumulated water of the water collecting part 113, and further improving the vaporization speed of the accumulated water.

Further, the bottom of the water collection portion 113 can be set to be a plane with the same size and shape as the upper surface of the steam generator 120, so that the bottom wall of the steam generator 120 is attached to the bottom wall of the water collection portion 113, the heating area of the water collection portion 113 is increased when the water collection purpose is achieved, the heat utilization rate of the steam generator 120 is improved, and unnecessary energy consumption is saved.

In an embodiment of the present invention, the water collecting portion 113 may be formed in a shape of a disk, and specifically, as shown in fig. 1, the water collecting portion 113 is formed in a shape of a plate with a desired depression, an upper end edge of a side wall of the plate is connected to the flow guiding portion 112, so that the water in the cooking cavity 111 is finally collected to a bottom of the plate of the water collecting portion 113, and the bottom of the plate may be set to be horizontal, thereby increasing a contact area between the water collecting portion 113 and the steam generator 120, further increasing a heating area of the water collecting portion 113, improving heat utilization efficiency of the steam generator 120, and simultaneously increasing a speed of regasification of the water in the water collecting portion 113.

In one embodiment of the present invention, the water collecting part 113 may be an aluminum piece. The aluminum has good heat conductivity and low price, so that the cost of the product is reduced under the condition of ensuring good heat conductivity, and the cost of the steam box 100 is further reduced.

In one embodiment of the present invention, as shown in fig. 3, the steam box 100 may further include a housing, the cavity 110 is disposed in the housing, a mounting cavity is defined between a lower surface of the cavity 110 and the housing, and the steam generator 120 is disposed in the mounting cavity. Wherein, the housing isolates the cavity 110 from the steam generator 120, thereby preventing external impurities from entering into the cavity 110, and ensuring the safety and sealing performance of the steam box 100.

In one embodiment of the present invention, as shown in fig. 1, the steam box 100 may be a steam box 100 having only a steaming function, and the steam box 100 may also be a steam oven having both steaming and baking functions. Thus, in use, the steam box 100 can perform a steaming function and a baking operation, thereby implementing a function of a steam oven.

Specifically, when the steam box 100 enters the baking mode, the controller 160 transmits a signal that the water pump 150 does not pump water, and the steam generator 120 is only used for heating and does not generate steam, so that only food is heated, and the baking effect is achieved.

According to the control method of the steam box 100 of the second aspect embodiment of the present invention, the steam box 100 is the steam box 100 of the first aspect embodiment of the present invention, the steam box 100 has a water accumulation removing mode, and the control method may include: when the steam box 100 is in the water accumulation removing mode, the heating element in the steam generator 120 is activated, and the water inlet pipe 130 of the steam generator 120 does not supply water into the steam generator 120. Thus, under the condition that the accumulated water in the cooking cavity 111 is not increased any more, the steam generator 120 continues to heat the accumulated water, so that the accumulated water in the steam box 100 is eliminated, and the efficiency of removing the accumulated water is improved.

According to the control method of the steam box 100, accumulated water is prevented from being accumulated in the cooking cavity 111, further, the environment pollution in the cooking cavity 111 caused by the breeding of bacteria in the accumulated water is avoided, the environment in the steam box 100 is more sanitary, and meanwhile, compared with the situation that a heating element is additionally arranged for removing the accumulated water at the bottom of the cooking cavity 111 in the related art, the accumulated water at the bottom of the cooking cavity 111 is heated by directly utilizing the steam generator 120 for generating steam, so that the number of parts in the steam box 100 can be reduced.

In one embodiment of the present invention, the heating elements of the steam generator 120 are turned off when the thermal inertia of the surface temperature rise of the steam generator 120 is less than a predetermined thermal inertia in the sump removal mode. It should be noted that, when there is water in the water collection portion 113, the thermal inertia of the surface temperature rise of the steam generator 120 is large, the temperature rise speed is slow, when there is no water in the water collection portion 113, the thermal inertia of the surface temperature rise of the steam generator 120 is small, the temperature rise speed is fast, whether there is water in the water collection portion 113 of the steam box 100 is determined by detecting the thermal inertia of the surface temperature rise of the steam generator 120, when the thermal inertia of the surface temperature rise of the steam generator 120 is smaller than the predetermined thermal inertia, it is indicated that there is no water in the water collection portion 113, then the closing of the heating element of the steam generator 120 is controlled, and the potential safety hazard caused by the no-load operation of the heating element is avoided.

Here, the thermal inertia means: when the temperature of the environment where the object is located changes instantaneously, the hysteresis of the temperature change of the object depends on the specific heat capacity and the mass of the object. The predetermined thermal inertia may be a preset value preset before the steam box 100 leaves a factory, and the predetermined thermal inertia values may be different for different heating powers and different steam box models.

In an embodiment, since the existence of the accumulated water may change the heating rate of the surface of the steam generator 120, the heating rate of the surface of the steam generator 120 (the heating rate refers to a value of temperature rise of the heating element per unit time during heating) may be detected to control the turning off of the heating element, so as to achieve the purpose of eliminating the accumulated water.

Wherein, the realization of removing the ponding mode can be after the work that steam ager 100 evaporates is accomplished, discover to still have ponding in culinary art chamber 111, control steam ager 100 through the control button that is located steam ager 100 and get into and remove the ponding mode. Also can be at the in-process of steaming food, there is ponding steam ager 100 through detection device detects in the culinary art chamber 111, removes the ponding mode through controller control steam ager 100 entering, from this, avoids ponding gathering in culinary art chamber 111, and then has avoided the bacterium of ponding to breed and cause the environmental pollution in culinary art chamber 111, makes the environment in the steam ager 100 more sanitary.

In an embodiment of the present invention, the steam box 100 further has a steaming mode, and the control method further includes: when the steam box 100 is in the steaming mode, water is supplied into the steam generator 120 at a first preset water supply speed, and a heating element of the steam generator 120 is started; so that a sufficient amount of water is converted into steam into the cooking chamber 111 to process the food in the cooking chamber 111.

When the steam box 100 is in the steaming mode and there is accumulated water in the cooking cavity 111, the accumulated water may be heated again in the water collecting part 113 to become steam for steaming work. At this time, the water flow rate into the steam generator 120 is reduced to not more than the second predetermined water flow rate. Wherein, the second predetermined water speed of leading to is less than first predetermined water speed of leading to, when the ponding in the culinary art chamber 111 reaches predetermined volume, the water yield that gets into culinary art chamber 111 can reduce, because ponding can evaporate once more, and then makes the total amount of steam still be in stably, under the condition that does not influence the steam ager 100 and steams the effect, has saved the water resource simultaneously.

The first predetermined water flow rate is set according to the amount of water required for the steaming operation of the cooking cavity 111, and the second predetermined water flow rate is set according to the amount of water required for the operation of the cooking cavity 111 after removing the water vapor evaporated from the accumulated water in the case that the accumulated water exists in the cooking cavity 111. The first predetermined water flowing speed and the second predetermined water flowing speed may be preset values preset before the steam box 100 leaves a factory, and the predetermined thermal inertia values may be different for different heating powers and different steam box models.

A steam box 100 according to one embodiment of the present invention will be described with reference to fig. 1.

Referring to fig. 1, a steam box 100 according to an embodiment of the present invention may include: a chamber 110, a steam generator 120, a water inlet pipe 130, an air outlet pipe 140, a water pump 150, and a controller 160.

As shown in fig. 1, a cooking cavity 111 is defined in the cavity 110, a bottom wall of the cooking cavity 111 may include a flow guide part 112 and a water collection part 113, and a vent hole 114 may be provided on a rear wall of the cooking cavity 111.

As shown in fig. 1, the steam generator 120 may include: a steam generator shell 121, heat exchange tubes 122, heating tubes 123 and a temperature sensor 124.

In a specific steaming process, as shown in fig. 1, firstly, the water inlet pipe 130 is connected to an external water pipe, the steam box 100 is powered on, then the controller 160 transmits a heating signal to the steam generator 120, when the temperature of the steam generator 120 reaches a preset temperature, the controller 160 transmits a water pumping signal to the water pump 150, water in the water inlet pipe 130 enters the steam generator 120, since the temperature of the steam generator 120 at this time is much higher than the boiling point of water, the temperature of the water rapidly rises to be vaporized into steam, and the steam enters the cooking cavity 111 through the air outlet pipe 140 to steam food.

In the process of steaming food, steam can be condensed into water drops in the cooking cavity 111 and attached to the side, the top and the bottom wall of the cooking cavity 111, due to the existence of gravity, the water drops can be collected to the bottom wall of the cooking cavity 111 finally, accumulated water enters the water collecting part 113 through the flow guide part 112 of the bottom wall, due to the large specific heat capacity of water, the speed of temperature change of the upper surface of the steam generator 120 detected by the temperature sensor 124 becomes slow, the thermal inertia becomes large, and then the controller 160 transmits a signal for reducing the water injection amount to the water pump 150, in the whole process, the temperature of the steam generator 120 is maintained at the preset temperature all the time, the steam generator 120 can heat the water collecting part 113, so that the accumulated water in the water collecting part 113 is vaporized again, and the effect of recycling is achieved. In the process, the amount of water supplied to the steam generator 120 is reduced, so that the amount of water vapor generated by the steam generator 120 is reduced, the accumulated water in the water collecting part 113 is vaporized again to be changed into water vapor, and the total amount of water vapor in the whole steaming process is ensured not to be reduced, and the use of water is reduced to a certain extent.

When the user opens the steam box 100 after the steaming operation is finished and finds that there is water accumulated at the bottom, the user presses a control key for removing the water accumulated in the cavity, and then the controller 160 transmits a signal for heating but not heating the water to the steam generator 120, evaporates the water accumulated at the bottom of the cavity 110 by heat, and then removes the water accumulated in the cavity from the exhaust hole 114. The controller 160 determines the processing progress of the accumulated water by the temperature change speed of the surface of the steam generator 120, for example, when the temperature rise speed of the surface of the steam generator 120 is increased to a certain degree through data, it indicates that the current accumulated water is completely removed, and at this time, the accumulated water is processed, the power supply is pulled off, and the operation is completed.

When the steam box 100 is only used for baking, the controller 160 may transmit a signal to heat the food but not to supply water to the steam generator 120, so as to bake the food.

According to the steam box 100 disclosed by the invention, the steam generator 120 capable of heating the bottom of the cooking cavity 111 is arranged on the lower side of the bottom wall of the cooking cavity 111, so that steam can be generated to cook the steam box 100 in the cooking process, and accumulated water on the bottom wall of the cooking cavity 111 can be removed, so that the pollution to the environment in the cooking cavity 111 caused by the breeding of bacteria in the accumulated water is avoided, and the environment in the steam box 100 is more sanitary.
