Different gas sources have different heat values and rated pressures, so that the gas quantities required for generating the same heat load are different, and the gas flows corresponding to the different gas sources are different. For example, in a gas range with a heat load of 4.5kW, about 160L/H of liquefied petroleum gas is needed, and 450L/H of natural gas is needed, that is, the gas flow rate of circulating natural gas should be greater than that of circulating liquefied petroleum gas. The gas flow provided by the existing gas stove is fixed and unchanged, and is only suitable for a single gas source. Based on this, this application provides a gas adjusting device and gas-cooker.

The gas regulating device provided by the application is introduced firstly.

Referring to fig. 1 and 3, in an embodiment of the present application, a gas regulating device 100 is provided, which includes a gas valve 110, an air inlet pipe 120, and a regulating member 130. The gas valve 110 has a gas passage. The air inlet pipe 120 has an air inlet end 1211, an air outlet end 1212, and an air inlet channel 121 communicating between the air inlet end 1211 and the air outlet end 1212, wherein the air inlet end 1211 is used for connecting an air source, and the air outlet end 1212 is connected to a gas channel of the gas valve 110. The adjusting member 130 is movably disposed in the air inlet tube 120, and the adjusting member 130 is controlled to change the flow rate of the fuel gas entering the fuel gas passage through the air inlet passage 121 during the movement of the adjusting member 130 relative to the air inlet tube 120.

In the gas regulating device 100, the gas provided by the gas source enters the gas channel of the gas valve 110 through the gas inlet channel 121 of the gas inlet pipe 120, and finally enters the burner through the gas channel to provide the gas for the burner. When a user needs to replace different types of gas, the adjusting member 130 is controlled to move relative to the gas inlet pipe 120, and during the moving process, the adjusting member 130 can change the gas flow entering the gas passage through the gas inlet passage 121, that is, change the gas flow provided by the gas adjusting device 100. Compared with the prior art, the gas stove provided with the gas adjusting device 100 can be suitable for various gas sources, and a user does not need to replace a new gas stove when replacing the gas source type, so that great convenience is brought to the user, and the cost performance of the gas stove is also improved.

The adjusting piece 130 can change the gas flow entering the gas channel through the gas inlet channel (121) in various ways. Illustratively, the adjuster 130 directly changes the flow area of the intake passage (121) when active. Of course, the schemes in the following examples can also be adopted.

In some embodiments, the regulating member 130 has a regulating channel 132. When the adjusting member 130 moves to the first flow rate position relative to the air inlet pipe 120, the air inlet passage 121 is directly communicated with the gas passage. And when the adjusting member 130 moves to the second flow position relative to the air inlet pipe 120, the air inlet passage 121 is communicated with the gas passage through the adjusting flow passage 132. The gas flow corresponding to the regulating member being located at the first flow rate position is greater than the gas flow corresponding to the regulating member being located at the second flow rate position.

In this embodiment, when the adjusting member 130 moves to the first flow rate position, at this time, the air inlet channel 121 is directly communicated with the gas channel, and the gas flow rate provided by the whole gas adjusting device 100 is relatively large, so that the device is suitable for a gas source (such as natural gas) with a relatively large required gas flow rate. When the adjusting member 130 moves to the second flow rate position, in which the air inlet channel 121 is communicated with the gas channel through the adjusting flow channel 132 of the adjusting member 130, the gas flow rate provided by the whole gas adjusting device 100 is small (determined by the flow rate of the adjusting flow channel), and is suitable for a gas source (such as liquefied petroleum gas) requiring a small gas flow rate. In this way, when the type of the air source connected to the air inlet pipe 120 is changed, the position of the adjusting member 130 in the air inlet pipe 120 is changed to change the flow rate of the gas provided by the gas adjusting device 100.

In actual operation, because the gas sources mainly include liquefied petroleum gas and natural gas, the adjusting member 130 can switch between the first flow position and the second flow position to adapt the gas flow provided by the gas adjusting device 100 to the two gas sources, so that the operation by a user is facilitated, the flow size does not need to be adjusted by the user, the adjusting process is simplified, and the flow adjustment is more accurate. Meanwhile, the adjusting member 130 is provided with an adjusting flow passage 132, and the flow rate of one specification of the gas adjusting device 100 can be determined through the adjusting flow passage 132, so that quantification and accurate control of the flow rate of the gas adjusting device 100 are facilitated. In addition, the gas regulating device 100 does not need to be additionally provided with other accessories, and the gas flow can be controlled only by arranging the regulating part 130 in the gas inlet pipe 120, so that the structure is simple and the operation is convenient.

It is understood that the gas channel has a gas inlet 111 and a gas outlet 112, the gas outlet 112 is used for connecting the burner, and the gas inlet 111 is used for connecting the gas outlet end 1212 of the gas inlet tube 120.

In some embodiments, the adjusting member 130 has an adjusting end 131, and the adjusting channel 132 is opened at the adjusting end 131. When the adjusting member 130 moves to the first flow position relative to the air inlet pipe 120, the adjusting end 131 exits from the air inlet 111 of the gas channel, and when the adjusting member 130 moves to the second flow position relative to the air inlet pipe 120, the adjusting end 131 seals the air inlet 111 of the gas channel and keeps the adjusting flow passage 132 communicated with the gas channel.

In this embodiment, the gas regulator device flow rate change is achieved by the regulator end 131 exiting and sealing the gas inlet 111 of the gas passageway. Specifically, when the adjustment end 131 is located at the first flow rate position, the adjustment end 131 exits the intake port 111, and the portion of the intake passage 121 located between the adjustment end 131 and the intake port 111 communicates with the intake port 111, thereby allowing the intake passage 121 to directly communicate with the gas passage. When the adjusting end 131 is located at the second flow position, the adjusting end 131 seals the air inlet 111, the air inlet channel 121 does not exist between the adjusting end 131 and the air inlet 111, and the air inlet channel 121 is communicated with the gas channel through the adjusting flow passage 132. At this time, by controlling the adjusting end 131 to seal or withdraw from the air inlet 111, the adjusting end 131 can communicate the air inlet channel 121 and the gas channel by using the adjusting flow channel 132 thereof when in the second flow rate position, which helps to simplify the structure of the gas adjusting device.

Of course, in other embodiments, a matching groove may be provided in the intake channel 121, and the adjusting end 131 may be withdrawn or sealed from the matching groove when switching between the first flow position and the second flow position, when the adjusting end 131 is sealed with the matching groove, the intake channel 121 is communicated with the gas channel through the adjusting channel 132 on the adjusting end 131, and when the adjusting end 131 is withdrawn from the matching groove, the intake channel 121 is directly communicated with the gas channel.

In the embodiment, the air inlet pipe 120 further has a mounting passage 122 intersecting the air inlet passage 121, and the adjusting member 130 is movably disposed in the mounting passage 122. Wherein the adjustment end 131 is controlled to move along the extension direction of the mounting channel 122 between a first flow position exiting the air inlet 111 and a second flow position sealing the air inlet 111.

In this embodiment, the adjustment end 131 of the adjustment member 130 is movable between a first flow position exiting the air inlet 111 and a second flow position sealing the air inlet 111 as the adjustment member 130 moves along the mounting channel 122. In this case, the stroke of the adjusting member 130 is simple, which contributes to simplifying the structure of the entire gas adjusting device 100. Moreover, by mounting the adjusting member 130 to the mounting channel 122, the mounting channel 122 can be used to guide the movement of the adjusting member 130, which helps to ensure that the adjusting end 131 is accurately sealed with the air inlet 111.

Further, referring to fig. 1 and 2, the air inlet 111 is a bell mouth, the adjusting end 131 is a tapered end adapted to the bell mouth, and the outer diameter of the tapered end gradually increases toward a direction away from the air inlet 111.

When the tapered end is engaged with the bell mouth, the adjusting end 131 seals the air inlet 111, and at this time, the air inlet channel 121 cannot be directly communicated with the air inlet 111 (i.e., directly communicated with the gas channel), but is communicated with the gas channel through the adjusting flow channel 132 in the adjusting member 130. When the tapered end exits the bell mouth, the inlet port 111 communicates directly with the inlet passage 121, that is, the gas passage communicates directly with the inlet passage 121. In this embodiment, the air inlet 111 and the adjustment end 131 are arranged to be in conical fit, which helps to achieve complete sealing of the air inlet 111 and the adjustment end 131.

In other embodiments, the adjustment end 131 may have an inverted bell mouth, and the inlet 111 may have a tapered sidewall that matches the inverted bell mouth. Of course, the configuration of the adjustment end 131 and the air inlet 111 is not limited thereto as long as it is possible to achieve sealing or exit of the adjustment end 131 from the air inlet 111 during movement.

Of course, in other embodiments, the adjuster 130 switches between the first and second flow rate positions as well as rotating within the intake pipe 120. For example, the air inlet is an arc-shaped opening, the adjusting end 131 of the adjusting member 130 is an arc-shaped end adapted to the arc-shaped opening, when the adjusting member 130 rotates to the first flow position, the arc-shaped end exits the arc-shaped opening, so that the arc-shaped opening is directly communicated with the air inlet channel 121, and then the air inlet channel and the gas channel 121 are directly communicated, when the adjusting member 130 rotates to the second flow position, the arc-shaped end is engaged with the arc-shaped opening, the arc-shaped end seals the arc-shaped opening, at this time, the arc-shaped opening is not directly communicated with the air inlet channel 121, so that the air inlet channel 121 is communicated with the gas channel through the adjusting flow channel 132.

It should be noted that, when the adjusting member 130 is located at the first flow rate position, the adjusting end 131 exits the air inlet 111, at this time, the air inlet 111 is directly communicated with the air inlet channel 121, and the adjusting flow passage 132 of the adjusting member 130 may be communicated with the air inlet channel 121 or may not be communicated with the air inlet channel 121.

Specifically, referring to fig. 1 and 2, the adjusting flow passage 132 includes a first flow passage 1321 and a second flow passage 1322, the first flow passage 1321 penetrates the adjusting end 131 in a first direction perpendicular to the moving direction of the adjusting member 130, and the second flow passage 1322 penetrates the adjusting end 131 in the moving direction of the adjusting member 130 and is connected to the first flow passage 1321.

As can be appreciated, due to the intersecting arrangement of the mounting passage 122 and the intake passage 121, when the adjusting member 130 is located at the second flow rate position, the first flow passage 1321 communicates with the intake passage 121, and the second flow passage 1322 communicates with the first flow passage 1321 and the gas passage. The fuel gas in the intake passage 121 enters the fuel gas passage through the first flow passage 1321 and the second flow passage 1322.

Further, referring to fig. 1, 2 and 3, the circumferential side wall of the adjusting member 130 has a groove 133 recessed in the first direction, and the first flow passage 1321 penetrates a groove bottom of the groove 133.

At this time, when the adjusting member 130 is located at the second flow rate position, the gas in the gas inlet passage 121 enters the gas passage through the groove 133, the first flow passage 1321, and the second flow passage 1322. The groove 133 is provided to allow the gas in the air inlet passage 121 to smoothly enter the first flow passage 1321, so as to prevent the inlet of the first flow passage 1321 from being blocked by the inner wall of the air inlet passage 121, and prevent the gas from smoothly entering the first flow passage 1321.

Preferably, the first flow passages 1321 include at least two, at least two first flow passages 1321 are radially arranged around an axis of the adjusting member 130 in a moving direction thereof, and correspondingly, the grooves 133 are annularly arranged around the axis. At this time, the gas around the adjusting member 130 can enter the second flow channel 1322 through the first flow channel 1321 in various orientations, which facilitates the gas entering the adjusting flow channel 132.

In the embodiment, referring to fig. 1, 2 and 3, both ends of the mounting passage 122 in the extending direction thereof communicate with the outside of the intake passage 121 and the intake pipe 120, respectively. One end of the adjusting member 130 in the moving direction thereof is an adjusting end 131, and the other end is a force bearing end 134, and the force bearing end 134 is used for supplying an external force to make the adjusting member 130 move under the driving of the external force.

In practice, when the user needs to switch the air supply type, the position of the adjusting member 130 can be changed by moving the adjusting member 130 along the mounting channel 122 by acting on the force-bearing end 134. Therefore, the structure of the whole device can be greatly simplified, and the manufacturing cost and the use cost of a user are reduced. Illustratively, a push-pull handle is provided at the force-bearing end 134, and a user can act on the push-pull handle to move the adjustment member 130. Of course, the following embodiments may be adopted.

Further, referring to fig. 1, 2 and 3, the circumferential sidewall of the adjusting member 130 has a first coupling portion 135 provided to extend in the moving direction thereof. The inner wall of the installation passage 122 has a second coupling portion 1221 coupled with the first coupling portion 135, and the first coupling portion 135 and the second coupling portion 1221 are movably coupled in the moving direction of the adjuster 130. In actual operation, when a user acts on the force-bearing end 134, the first coupling portion 135 can be moved along the second coupling portion 1221, so that the adjusting member 130 can be moved. Wherein, preferably, the first mating portion 135 is located between the adjustment flow channel 132 and the force-bearing end 134.

Specifically, the first coupling portion 135 is an external thread portion, and the second coupling portion 1221 is an internal thread portion matching the external thread portion. When a user applies a torque to the force-receiving end 134, the male threaded portion rotates along the female threaded portion and moves along the female threaded portion under the torque, thereby effecting movement of the adjustment member 130 within the mounting channel 122. At this time, the first mating portion 135 and the second mating portion 1221 are connected by screw-fitting, and the movement of the adjusting member 130 can be further adjusted while the adjusting member 130 is connected to the mounting passage 122, which is simple in structure and convenient to manufacture. In this case, the adjusting member 130 may be made of a common member such as a bolt, and thus, the manufacturing cost is low. Of course, the first mating portion 135 and the second mating portion 1221 may also be a slide rail and a slide rail.

It should be noted that, in other embodiments, the adjusting member 130 may also perform position adjustment without external force provided by the user, for example, the gas adjusting device 100 further includes a driving mechanism and a controller, the controller is connected with the driving mechanism through signals, the driving mechanism is disposed on the installation channel 122, and the driving mechanism is connected with the adjusting member 130 in a transmission manner. The controller receives a switching command from a user and controls the actuation of the driving mechanism, which controls the movement of the adjusting member 130 along the mounting channel 122 in response to the controller. The driving mechanism may be a telescopic motor member or other members capable of driving the adjusting member 130 to move, which is not described herein in detail. The switching instruction can be generated by pressing a control button by a user, the control button generates an electric signal to the controller when being pressed, and the controller controls the driving mechanism to act according to the electric signal. The switching instruction can also be generated by a user based on the operation of a control panel, and the control panel is in signal connection with the controller.

In a preferred embodiment, referring to fig. 1, 2 and 3, the gas regulator 100 further includes a sealing ring 140, wherein the sealing ring 140 is disposed on the regulating member 130 and sealingly connects the regulating member 130 and the installation passage 122. At this time, the adjusting member 130 and the installation passage 122 are hermetically connected by the sealing ring 140, so that the gas can be prevented from leaking through a gap between the adjusting member 130 and the installation passage 122 to cause a safety accident. Specifically, the sealing ring 140 is sleeved on the force-bearing end 134, an annular groove is circumferentially formed in a circumferential side wall of the force-bearing end 134, the sealing ring 140 is disposed in the annular groove and limited between the annular groove and an inner wall of the installation channel 122, and in the moving process of the adjusting member 130, the sealing member and the inner wall of the installation channel 122 are always in sealing connection. The sealing ring 140 may be an O-ring.

In some embodiments, referring to fig. 1 and 3, the number of the gas valves 110 and the adjusting members 130 is at least one, the gas inlet pipe 120 includes at least one gas outlet end 1212, each gas outlet end 1212 is correspondingly connected to a gas channel of one gas valve 110, and at least one adjusting member 130 is in one-to-one correspondence with at least one gas valve 110. Each adjusting member 130 is controlled to vary the flow rate of gas entering the gas passage of the corresponding gas valve 110 through the gas inlet passage 121 during the movement relative to the gas inlet pipe 120.

In practical use, the gas entering the gas inlet pipe 120 through the gas inlet end 1211 can be divided into at least two paths, each path corresponds to one gas valve 110, and each adjusting member 130 corresponds to adjust the flow rate of the gas entering one gas valve 110 through the gas inlet channel 121. At this time, the gas stove of at least one burner can be used. Preferably, the number of the gas valve 110 and the adjusting member 130 is two.

Further, each gas valve 110 comprises two gas outlets 112, wherein one gas outlet 112 is used for supplying gas to the outer fire cover of the burner, and the other gas outlet 112 is used for supplying gas to the inner fire cover of the burner.

In one embodiment, the gas regulator 100 is used when the user determines the type of the gas source, and when the gas source is natural gas, the user rotates the adjusting member 130 to move the adjusting member to the first flow position, where the gas flow rate in the gas inlet pipe 120 is the maximum. When the gas source is liquefied petroleum gas, the user rotates the adjusting member 130 to move the adjusting member to the second flow rate position, and the flow rate of the gas in the gas inlet pipe 120 is the minimum, i.e., the flow rate of the adjusting flow passage 132).
