Description

Technical Field

[0001] This utility model relates to the field of gas stoves, and in particular to a gas valve and a gas stove including the same. Background Technology

[0002] To achieve instantaneous opening or closing, traditional stir-fry valves typically require a dedicated stir-fry channel and auxiliary control structures (such as external bypass pipes and auxiliary drive mechanisms) installed outside the valve body. This external stir-fry channel necessitates additional sealing interfaces, connectors, and support structures, resulting in a bulky valve with an increased number of components. This not only increases manufacturing costs but also complicates installation and maintenance. Furthermore, the circuitous path of the external stir-fry channel prolongs the response time of the medium flow, making it difficult to meet the instantaneous action requirements of high-frequency opening and closing or emergency shut-off scenarios. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the existing external stir-fry valve in which the structure is complex and the gas flow path is too long, and to provide a gas valve and a gas stove including the same.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] This utility model provides a gas valve, which includes a plug valve and a stir-fry valve. The plug valve includes a plug valve body, which is provided with an air inlet channel, a main valve chamber, a normal gas channel, a stir-fry channel, and a connecting channel. The air inlet of the air inlet channel is used to communicate with a gas supply device. The air inlet of the main valve chamber is connected to the air outlet of the air inlet channel. The first air inlet of the normal gas channel and the air inlet of the stir-fry channel are both connected to the air outlet of the main valve chamber. The two ends of the connecting channel are respectively connected to the second air inlet of the normal gas channel and the air outlet of the stir-fry channel. The gas outlet of the ordinary gas passage is used to communicate with the mixing chamber; the stir-fry valve includes a stir-fry valve core and a drive unit, at least a portion of the stir-fry valve core extends into the connecting passage, and the drive unit is connected to the stir-fry valve core and used to control the rotation of the stir-fry valve core within the connecting passage, so that the stir-fry valve core switches between a normal state and a stir-fry state; in the normal state, the connecting passage is closed, and the ordinary gas passage and the stir-fry passage are not connected; in the stir-fry state, the connecting passage is open, and the ordinary gas passage and the stir-fry passage are connected.

[0006] In this design, the stir-fry channel is housed within the stopcock valve body. A connecting channel links the stir-fry channel to the ordinary gas channel and provides space for the stir-fry valve. The drive unit rotates the stir-fry valve to control the opening and closing of the stir-fry channel, ensuring simple and reliable control even when it's integrated within the stopcock valve body. Since the main valve chamber supplies gas to the ordinary gas channel through the first inlet, and the stir-fry channel shares a portion of the ordinary gas channel with it, a separate external stir-fry channel is unnecessary. The added stir-fry channel connects to the second inlet of the ordinary gas channel, providing additional gas and thus increasing the gas supply to the ordinary gas channel, thereby achieving the stir-fry effect. This structure significantly simplifies the internal structure of the stir-fry channel within the stopcock valve body, avoiding the drawbacks of an external stir-fry channel that would make the gas valve structure overly complex, and ultimately reducing the time required for gas to pass through the stir-fry channel.

[0007] Preferably, the stir-fry valve core is rotatable about its own axis, and the stir-fry valve core is provided with a connecting cavity, the air inlet and the air outlet of the connecting cavity both penetrating the wall surface of the stir-fry valve core; in the normal state, the projection of the air inlet of the connecting cavity along the axial direction of the air outlet of the stir-fry channel on the stir-fry channel does not coincide with the air outlet of the stir-fry channel; and / or, the projection of the air outlet of the connecting cavity along the axial direction of the second air inlet on the ordinary gas channel does not coincide with the second air inlet; in the stir-fry state, the projection of the air inlet of the connecting cavity along the axial direction of the air outlet of the stir-fry channel on the stir-fry channel at least partially coincides with the air outlet of the stir-fry channel; and, the projection of the air outlet of the connecting cavity along the axial direction of the second air inlet on the ordinary gas channel at least partially coincides with the second air inlet.

[0008] In this design, the stir-fry valve core rotates around its own axis. When the stir-fry valve core rotates until the air inlet of the connecting cavity does not coincide with the air outlet of the stir-fry channel, or the air outlet of the connecting cavity does not coincide with the second air inlet, that is, when the air inlet or outlet of the connecting cavity faces the inner wall of the connecting channel, the stir-fry valve core blocks the connection between the stir-fry channel and the ordinary gas channel, thus placing the gas valve in a normal state. When the stir-fry valve core rotates until the air inlet of the connecting cavity coincides with the air outlet of the stir-fry channel, and the air outlet of the connecting cavity coincides with the second air inlet, that is, when the air inlet and outlet of the connecting cavity face the air outlet and the second air inlet of the stir-fry channel, respectively, the stir-fry valve core connects the stir-fry channel and the ordinary gas channel. Using the above structure, the opening and closing of the stir-fry channel can be controlled by controlling the rotation angle of the stir-fry valve core, thereby achieving different amounts of stir-fry gas when the connecting cavity and the stir-fry channel or the second air inlet are at different degrees of overlap, achieving precise control of the gas quantity.

[0009] Preferably, the projection of the air inlet of the connecting cavity along the axial direction of the air outlet of the stir-frying channel onto the stir-frying channel is completely coincident with the air outlet of the stir-frying channel; and the projection of the air outlet of the connecting cavity along the axial direction of the second air inlet onto the ordinary gas channel is completely coincident with the second air inlet.

[0010] In this design, the maximum amount of gas can be provided for stir-frying when the connecting cavity and the stir-frying channel or the second air inlet are completely overlapped, thereby increasing the stir-frying temperature.

[0011] Preferably, the axis of the air inlet of the communicating cavity is perpendicular to the axis of the air outlet.

[0012] In this design, the vertical relationship between the air inlet and outlet of the connecting cavity can change the direction of the gas, thereby making the positional relationship between the stir-fry channel and the ordinary gas channel parallel. This can further optimize the internal structure of the plug valve body and make the structure more compact.

[0013] Preferably, the drive unit is a motor.

[0014] In this solution, controlling the rotation of the stir-fry valve core by a motor can improve the overall automation level of the gas valve and further enhance the control precision of the stir-fry valve core.

[0015] Preferably, the stir-fry valve further includes a transmission assembly connected between the stir-fry valve core and the motor.

[0016] In this solution, a transmission assembly is installed between the motor and the stir-fry valve. By adjusting the transmission ratio of the transmission assembly, the motor can operate in its efficient torque range, avoiding overheating or burnout caused by directly driving an excessively large load.

[0017] Preferably, the transmission component is a gear assembly, which includes a first gear and a second gear that mesh with each other, the first gear being connected to the drive unit and the second gear being connected to the stir-fry valve core.

[0018] In this scheme, the transmission efficiency is high and the energy loss is low when using the first gear and the second gear for transmission.

[0019] Preferably, the portion of the stir-fry valve core extending into the connecting channel is provided with external threads, and the connecting channel is provided with internal threads, with the stir-fry valve core threadedly engaging with the connecting channel; in the normal state, the stir-fry valve core is located at the gas outlet of the stir-fry channel or at the second gas inlet to prevent the normal gas channel and the stir-fry channel from communicating; in the stir-frying state, the stir-fry valve core is located away from the gas outlet of the stir-fry channel or the second gas inlet to connect the normal gas channel and the stir-fry channel.

[0020] In this design, the stir-fry valve core is threaded into the connecting channel. Driven by the drive unit, the stir-fry valve core rotates to move along the axis of the connecting channel. When the stir-fry valve core is located at the gas outlet or second gas inlet of the stir-fry channel, it blocks the gas outlet or second gas inlet, thus preventing the connection between the stir-fry channel and the ordinary gas channel. When the stir-fry valve core is away from the gas outlet or second gas inlet of the stir-fry channel, the gas outlet or second gas inlet of the stir-fry channel is connected through the connecting channel. Using this structure, the distance the stir-fry valve core rotates in and out can be precisely controlled, thereby controlling the amount of gas entering the ordinary gas channel and improving the accuracy of temperature control during stir-frying.

[0021] Preferably, the axis of the air inlet and the axis of the air outlet of the connecting channel form an angle, and the axial direction of the connecting channel is parallel to the axial direction of the second air inlet; in the normal state, the projection of the stir-fry valve core along the axial direction of the air outlet of the stir-fry channel completely covers the air outlet of the stir-fry channel; in the stir-frying state, the projection of the stir-fry valve core along the axial direction of the air outlet of the stir-fry channel does not completely cover the air outlet of the stir-fry channel.

[0022] In this solution, the above structure allows the stir-fry valve core to be positioned in different locations, connecting or blocking the stir-fry channel and the ordinary gas channel, thereby changing the stir-fry state of the gas valve. This structure is characterized by its simplicity and low manufacturing cost.

[0023] This utility model also provides a gas stove, which includes the gas valve as described above.

[0024] In this design, the stir-fry channel is housed within the stopcock valve body. A connecting channel links the stir-fry channel to the ordinary gas channel and provides space for the stir-fry valve. The drive unit rotates the stir-fry valve to control the stir-fry channel, ensuring simple and reliable control of its opening and closing when it is integrated within the stopcock valve body. In addition to the main valve chamber supplying gas to the ordinary gas channel through the first inlet, the added stir-fry channel connects to the second inlet of the ordinary gas channel to provide additional gas, thereby increasing the gas supply and achieving the stir-fry effect. This structure significantly simplifies the internal structure of the stopcock valve body, avoiding the drawbacks of an externally placed stir-fry channel that would make the gas valve structure overly complex, and thus reducing the time required for gas to pass through the stir-fry channel.

[0025] The positive and progressive effects of this utility model are as follows:

[0026] The gas valve and gas stove including the present invention provide a stir-fry channel housed inside a stopcock valve body. A connecting channel connects the stir-fry channel to the ordinary gas channel and provides space for the stir-fry valve. The drive unit rotates the stir-fry valve to control the stir-fry channel, ensuring simple and reliable control of its opening and closing when the stir-fry channel is housed within the stopcock valve body. In addition to the main valve chamber supplying gas to the ordinary gas channel through the first air inlet, the added stir-fry channel connects to the second air inlet of the ordinary gas channel to provide additional gas, thereby increasing the gas supply to the ordinary gas channel and achieving the stir-fry effect. This structure greatly simplifies the internal structure of the stir-fry channel within the stopcock valve body, avoiding the drawbacks of an externally placed stir-fry channel that makes the gas valve structure overly complex, and thus reducing the time required for gas to pass through the stir-fry channel.

[0052] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0053] Example 1

[0054] like Figures 1-5 As shown, this embodiment provides a gas valve 100, which includes a stopcock valve 1 and a stir-fry valve 8; the stopcock valve 1 includes a stopcock valve body 2, and the stopcock valve body 2 is provided with an air intake channel 3, a main valve chamber 4, a normal gas channel, a stir-fry channel 6 and a connecting channel 7.

[0055] like Figure 2 As shown, the air inlet of the air intake channel 3 is used to connect with the gas supply equipment, and the air inlet of the main valve chamber 4 is connected with the air outlet of the air intake channel 3. The first air inlet 9 of the ordinary gas channel and the air inlet of the stir-fry channel 6 are both connected to the air outlet of the main valve chamber 4. The two ends of the connecting channel 7 are respectively connected to the second air inlet 10 of the ordinary gas channel and the air outlet of the stir-fry channel 6. The air outlet of the ordinary gas channel is used to connect with the mixing chamber. The ordinary gas channel can be an outer ring gas channel 5 or an inner ring gas channel. In this embodiment, the ordinary gas channel is an outer ring gas channel 5. The stir-fry valve 8 includes a stir-fry valve core 11 and a drive part. At least part of the stir-fry valve core 11 extends into the connecting channel 7. Preferably, the stir-fry valve core 11 is completely disposed in the connecting channel 7. The drive unit is connected to the stir-fry valve core 11 and is used to control the rotation of the stir-fry valve core 11 within the connection channel 7, so that the stir-fry valve core 11 switches between the normal state and the stir-fry state; in the normal state, the connection channel 7 is closed, and the outer ring gas channel 5 and the stir-fry channel 6 are not connected; in the stir-fry state, the connection channel 7 is open, and the outer ring gas channel 5 and the stir-fry channel 6 are connected.

[0056] Thus, by placing the stir-fry channel 6 inside the stopcock valve body 2, and connecting channel 7 connecting the stir-fry channel 6 to the ordinary gas channel, a space is provided for the stir-fry valve 8. The drive unit drives the stir-fry valve 8 to rotate and control the stir-fry channel 6, ensuring simple and reliable control of the opening and closing of the stir-fry channel 6 when it is built inside the stopcock valve body 2.

[0057] like Figure 4 As shown, the solid arrow indicates the flow path of the main valve chamber 4 supplying gas to the ordinary gas passage through the first air inlet 9, while the dashed arrow indicates the additional stir-frying passage 6 connecting to the second air inlet 10 of the ordinary gas passage, providing an additional gas flow path. Since the stir-frying passage 6 and the ordinary gas passage share a portion of the ordinary gas passage, there is no need to set up a separate external stir-frying passage 6. The additional gas supply increases the gas supply to the ordinary gas passage, thereby achieving the stir-frying effect. This structure greatly simplifies the internal structure of the stir-frying passage 6 within the stopcock valve body 2, thus avoiding the drawback of an external stir-frying passage 6 making the gas valve 100 structure overly complex, and thereby reducing the time required for gas to pass through the stir-frying passage 6.

[0058] In this embodiment, as Figure 3 As shown, the stir-fry valve core 11 can rotate around its own axis. The stir-fry valve core 11 has a connecting cavity 12, and the air inlet and outlet of the connecting cavity 12 both penetrate the wall of the stir-fry valve core 11. In normal state, the connecting cavity 12 can be set in the following three ways:

[0059] In the first case, the projection of the air inlet of the connecting cavity 12 onto the air outlet of the stir-frying channel 6 along the axial direction of the air outlet of the stir-frying channel 6 does not coincide with the air outlet of the stir-frying channel 6.

[0060] The second type is where the projection of the outlet of the connecting cavity 12 along the axial direction of the second inlet 10 onto the ordinary gas passage does not coincide with the second inlet 10.

[0061] The third type is where the projection of the air inlet of the connecting cavity 12 onto the air outlet of the stir-frying channel 6 along the axial direction of the air outlet of the stir-frying channel 6 does not coincide with the air outlet of the stir-frying channel 6. At the same time, the projection of the air outlet of the connecting cavity 12 onto the ordinary gas passage along the axial direction of the second air inlet 10 does not coincide with the second air inlet 10.

[0062] like Figure 2 As shown, this embodiment is the first type.

[0063] In the stir-frying state, the projection of the air inlet of the connecting cavity 12 along the axial direction of the air outlet of the stir-frying channel 6 on the stir-frying channel 6 at least partially coincides with the air outlet of the stir-frying channel 6; and the projection of the air outlet of the connecting cavity 12 along the axial direction of the second air inlet 10 on the outer ring gas channel 5 at least partially coincides with the second air inlet 10.

[0064] The stir-fry valve core 11 rotates around its own axis. When the inlet of the connecting cavity 12 does not coincide with the outlet of the stir-fry channel 6, that is, when the inlet of the connecting cavity 12 faces the inner wall of the connecting channel 7, the stir-fry valve core 11 blocks the connection between the stir-fry channel 6 and the outer ring gas channel 5, thus putting the gas valve 100 in a normal state. When the inlet of the connecting cavity 12 coincides with the outlet of the stir-fry channel 6, and the outlet of the connecting cavity 12 coincides with the second inlet 10, that is, when the inlet and outlet of the connecting cavity 12 face the outlet of the stir-fry channel 6 and the second inlet 10 respectively, the stir-fry valve core 11 connects the stir-fry channel 6 and the outer ring gas channel 5. With the above structure, the opening and closing of the stir-fry channel 6 can be controlled by controlling the rotation angle of the stir-fry valve core 11, thereby achieving different amounts of stir-fry gas when the connecting cavity 12 and the stir-fry channel 6 are at different degrees of overlap, thus achieving the effect of precise control of the amount of gas.

[0065] Furthermore, the projection of the air inlet of the connecting cavity 12 onto the stir-frying channel 6 along the axial direction of the air outlet of the stir-frying channel 6 is completely coincident with the air outlet of the stir-frying channel 6; and the projection of the air outlet of the connecting cavity 12 onto the outer ring gas channel 5 along the axial direction of the second air inlet 10 is completely coincident with the second air inlet 10.

[0066] Thus, when the connecting cavity 12 and the stir-frying channel 6 or the second air inlet 10 are completely overlapped, the maximum amount of gas for stir-frying can be provided, thereby increasing the stir-frying temperature.

[0067] Furthermore, such as Figure 2 and Figure 4 As shown, the axis of the air inlet of the connecting cavity 12 is perpendicular to the axis of the air outlet.

[0068] Thus, the vertical relationship between the air inlet and outlet of the connecting cavity 12 can change the direction of the gas, thereby making the positional relationship between the stir-fry channel 6 and the ordinary gas channel parallel, which can further optimize the internal structure of the plug valve body 2 and make the structure more compact.

[0069] In this embodiment, as Figure 2 As shown, the connecting cavity 12 is L-shaped, with one end of the L-shape being the air inlet and the other end being the air outlet. In other embodiments, the connecting cavity 12 can also be T-shaped, with the vertical end of the T-shape being the air inlet and one of the horizontal ends of the T-shape being the air outlet.

[0070] Furthermore, such as Figure 5 As shown, the drive unit is motor 13.

[0071] Thus, by controlling the rotation of the stir-fry valve core 11 by the motor 13, the overall automation level of the gas valve 100 can be improved, and the control accuracy of the stir-fry valve core 11 can be further improved.

[0072] Furthermore, such as Figure 5 As shown, the stir-fry valve 8 also includes a transmission assembly, which is connected between the stir-fry valve core 11 and the motor 13. By setting the transmission assembly between the motor 13 and the stir-fry valve 8, the transmission ratio of the transmission assembly can be adjusted to allow the motor 13 to operate in its efficient torque range, avoiding overheating or burnout caused by directly driving an excessively large load.

[0073] Furthermore, such as Figure 5 As shown, the transmission assembly is a gear assembly, which includes a first gear 14, a second gear 15, and a third gear 16 that mesh with each other. The first gear 14 is connected to the drive unit, the second gear 15 is connected to the stir-fry valve core 11, and the third gear 16 is meshed with the first gear 14 and the second gear 15. The number of gears can be adjusted as needed by those skilled in the art. For example... Figure 3 As shown, the second gear 15 can be integrally formed with the stir-fry valve core 11. Using the first gear 14 and the second gear 15 for transmission results in high transmission efficiency and low energy loss. In other embodiments, the transmission device can also be a belt or chain, etc.

[0074] Example 2

[0075] like Figure 6 and Figure 7 As shown, the other structures in this embodiment are the same as in Embodiment 1, except for the structure of the stir-fry valve core 11. In this embodiment, the stir-fry valve core 11 no longer has a communicating cavity 12, but is a solid structure. The axis of the air inlet of the connecting channel 7 and the axis of the air outlet form an angle. Preferably, the axis of the air inlet of the connecting channel 7 and the axis of the air outlet are perpendicular. Figure 7 As shown, the portion of the stir-fry valve core 11 that extends into the connecting channel 7 has an external thread, and the connecting channel 7 has an internal thread. The stir-fry valve core 11 and the connecting channel 7 are threadedly engaged. The threaded engagement between the stir-fry valve core 11 and the connecting channel 7 can be achieved in two ways:

[0076] In the first configuration, the axis of the connecting channel 7 is parallel to the axis of the gas outlet of the stir-fry channel 6, meaning the axis of the internal thread is parallel to the axis of the gas outlet of the stir-fry channel 6. In normal operation, the stir-fry valve core 11 is located at the gas outlet of the stir-fry channel 6 to prevent the ordinary gas passage from connecting with the stir-fry channel 6; in the stir-frying state, the stir-fry valve core 11 is moved away from the gas outlet of the stir-fry channel 6 to connect the ordinary gas passage with the stir-fry channel 6.

[0077] The second type involves connecting channel 7 with its axis parallel to the axis of the second air inlet 10, meaning the axis of the internal thread is parallel to the axis of the second air inlet 10. In normal operation, the projection of the stir-fry valve core 11 along the axis of the air outlet of the stir-fry channel 6 completely covers the air outlet of the stir-fry channel 6; in stir-fry mode, the projection of the stir-fry valve core 11 along the axis of the air outlet of the stir-fry channel 6 does not completely cover the air outlet of the stir-fry channel 6.

[0078] like Figure 6 As shown, this embodiment is the second type.

[0079] Thus, the stir-fry valve core 11 is threadedly engaged with the connecting channel 7, the drive unit is connected to the first gear 14, the upper part of the stir-fry valve core 11 is connected to the second gear 15, and the third gear 16 is meshed with the first gear 14 and the second gear 15. The tooth thickness of the second gear 15 is greater than that of the third gear 16. The stir-fry valve core 11 rotates under the drive of the drive unit and moves along the axis of the connecting channel 7 under the action of the internal thread.

[0080] When the stir-fry valve core 11 is located at the outlet or second inlet 10 of the stir-fry channel 6, it blocks the outlet or inlet 10, thus preventing the connection between the stir-fry channel 6 and the ordinary gas channel. When the stir-fry valve core 11 is away from the outlet or inlet 10, the outlet or inlet 10 is connected via the connecting channel 7. This structure allows for precise control of the distance the stir-fry valve core 11 rotates in and out, thereby controlling the amount of gas entering the ordinary gas channel and improving the accuracy of temperature control during stir-frying. This structure is simple and has low manufacturing cost.

[0081] Example 3

[0082] This embodiment provides a gas stove, which includes the gas valve 100 as described above.

[0083] Thus, by placing the stir-fry channel 6 inside the stopcock valve body 2, and connecting channel 7 connecting the stir-fry channel 6 to the ordinary gas channel, a space is provided for the stir-fry valve 8. The drive unit drives the stir-fry valve 8 to rotate, controlling the opening and closing of the stir-fry channel 6, ensuring simple and reliable control even when it is built into the stopcock valve body 2. In addition to the main valve chamber 4 supplying gas to the ordinary gas channel through the first air inlet 9, the added stir-fry channel 6 connects to the second air inlet 10 of the ordinary gas channel to provide additional gas, thereby increasing the gas supply to the ordinary gas channel and achieving the stir-fry effect. This structure greatly simplifies the internal structure of the stir-fry channel 6 within the stopcock valve body 2, avoiding the drawback of an externally placed stir-fry channel 6 making the gas valve 100 structure overly complex, and thus reducing the time required for gas to pass through the stir-fry channel 6.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
