Description

Technical Field

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

[0002] Currently, integrated gas stoves are widely favored in the market. However, due to the need to integrate other kitchen appliances such as dishwashers, ovens, and steamers below the gas stove, the space under the stovetop is limited, resulting in a compact and complex structure. This compression of the internal dimensions of the stovetop leads to limitations on the height of the gas valve and a significant reduction in the valve's diaphragm height. Consequently, the adjustable range of the inner and outer ring flames of the burner is very small. As consumers increasingly demand more precise flame control, the adjustable range of the gas valves in integrated gas stoves is no longer sufficient to meet their needs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defect of the small gas adjustment range of gas valves used in integrated stove products in the prior art, 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] A gas valve includes a gate and a valve body. The valve body has a gas inlet channel and a plurality of gas outlet channels respectively connected to different gas rings. The gas inlet channel is connected to the gate through a gas inlet, and each of the gas outlet channels is connected to the gate through a corresponding gas outlet. The gas inlet and each of the gas outlets are arranged on the side of the gate, and the gas inlet and at least one of the gas outlets are arranged flush with each other in the height direction of the gate.

[0006] This gas valve frees up height space by placing the gas inlet channel of the valve body and the gas inlet of the octagon on the side of the octagon, and aligning the gas inlet of the valve body with at least one gas outlet. This allows for larger gas inlet and outlet sizes even when the valve body height is limited, thereby increasing the gas adjustable range of the gas valve. When this gas valve is used in gas stoves with limited height dimensions, such as integrated stove products, the gas adjustable range provided by the gas valve can still meet the user's needs.

[0007] Preferably, the number of the shut-off valves is at least two, and the gas valve further includes a transmission mechanism, with each shut-off valve connected to the transmission mechanism to achieve synchronous rotation;

[0008] The number of gas intake channels corresponds to the number of closures. Each gas intake channel is connected to the corresponding closure through the gas outlet, and each gas outlet channel is connected to the corresponding closure through the gas inlet.

[0009] This gas valve increases the number of gates, which rotate synchronously through a transmission mechanism. This reduces the number of gas outlet channels on each gate while keeping the total number of gas outlet channels constant. As a result, the size of the gas outlet and the gas inlet of the gas inlet channels can be further increased, thereby improving the gas valve's adjustable range.

[0010] This structural design is particularly suitable for burners with three or more gas rings, and can significantly reduce the number of gas intake channels that need to be installed on each octagon.

[0011] Preferably, the gas outlet passage connected to the inner gas ring is defined as the first gas outlet passage, the gas outlet passage connected to the middle gas ring is defined as the second gas outlet passage, and the gas outlet passage connected to the outer gas ring is defined as the third gas outlet passage, wherein the first gas outlet passage is connected to one of the closed elements, and the second and third gas outlet passages are connected to the other closed element.

[0012] When applied to a burner with three gas rings (inner ring, middle ring, and outer ring), one gas outlet passage connected to the inner gas ring is connected to a closed element, while the two gas outlet passages connected to the middle and outer gas rings are connected to another closed element. This reasonable arrangement of connections allows the inner ring to have a relatively larger and more independent adjustable space.

[0013] Preferably, the closure connected to the first outlet passage is defined as the first closure, and the gas inlet passage connected to the first closure is defined as the first inlet passage.

[0014] In the height direction of the first closure, the gas inlet of the first air intake channel and the gas outlet of the first air outlet channel are arranged flush.

[0015] In this structural design, the gas inlet of the first intake channel and the gas outlet of the first outlet channel are arranged flush in the height direction of the first closure, so as to make reasonable use of the height space of the gas valve and increase the height of the gas outlet of the first outlet channel connected to the inner ring, thereby meeting the gas adjustment needs of the inner ring over a wide range.

[0016] Preferably, the closure that communicates with the second and third outlet passages is defined as the second closure, and the gas intake passage that communicates with the second closure is defined as the second intake passage;

[0017] In the height direction of the second closure, the gas inlet of the second air intake channel, the gas outlet of the second air outlet channel, and the gas outlet of the third air outlet channel are all arranged at the same level.

[0018] This structural design aligns the gas inlet of the second intake channel, the gas outlet of the second outlet channel, and the gas outlet of the third outlet channel along the height of the second valve. This optimizes the vertical space of the gas valve, allowing for larger gas outlet heights in both the second outlet channel (connecting to the middle ring) and the third outlet channel (connecting to the outer ring), thus meeting the wide-range gas adjustment needs of both the middle and outer rings. Although both gas outlets for the middle and outer rings correspond to the same valve (the second valve), during routine flame adjustment, the flame intensity of the middle and outer rings is typically activated or deactivated synchronously. Therefore, aligning the two gas outlets for the middle and outer rings with the second valve does not affect the flame adjustment accuracy of the two gas rings.

[0019] Preferably, along the rotation direction of the second occluder, the gas inlet of the second air intake channel, the gas outlet of the second air outlet channel, and the gas outlet of the third air outlet channel are arranged sequentially.

[0020] With this structural design, as the gas is gradually opened by rotating the second occluder in the forward direction, the gas inlet of the second intake channel is first connected to the gas outlet of the second outlet channel of the corresponding middle ring, and then connected to the gas outlet of the third outlet channel of the corresponding outer ring, so as to meet the user's daily ignition adjustment needs.

[0021] Meanwhile, as the gas is gradually shut off by rotating the second valve in the opposite direction, the gas inlet of the second intake channel is first cut off from the gas outlet of the third outlet channel of the corresponding outer ring, and then cut off from the gas outlet of the second outlet channel of the corresponding middle ring, which can also meet the user's daily ignition adjustment needs.

[0022] Preferably, the transmission mechanism achieves synchronous rotation between the closed elements through gear transmission.

[0023] The synchronous rotation between the components is achieved by using gear transmission, which results in higher transmission accuracy and better synchronization compared to other synchronous transmission schemes.

[0024] Preferably, the transmission mechanism includes a first gear, a second gear, and a third gear, wherein the first gear is disposed on one of the valve stems, the third gear is disposed on the other valve stem, and the second gear is rotatably disposed on the valve body and meshes with the first gear and the third gear respectively.

[0025] This structural design, by setting a second gear on the valve body to mesh with the first and third gears on the two valve stems respectively, allows the two valve stems to rotate in the same direction compared to other gear transmission designs, thus reducing the design difficulty of the gas valve's on / off relationship.

[0026] Preferably, the valve body includes a valve body and a cover plate that are detachably connected. The cover plate is installed upward along the height direction of the valve body at the bottom of the valve body, and the valve body and the cover plate together form the gas intake passage.

[0027] This structural design creates a gas intake channel inside the valve body by combining the valve body and the cover plate. This eliminates the size limitations of holes formed by drilling on the surface of parts, allowing for a larger gas intake channel, reduced gas intake resistance, stable operation of the gas valve, and reduced gas fluctuations during ignition adjustment.

[0028] A gas stove appliance includes a gas valve as described above.

[0029] This gas stove, by employing the aforementioned gas valve, can provide a relatively large adjustable range of gas even when the space below the stovetop, i.e., the internal space of the stove chassis, is limited in height, thus meeting the user's wide range of flame adjustment needs.

[0030] The positive and progressive effects of this utility model are as follows:

[0031] Through structural layout improvements, the gas valve and the gas stove containing it can free up height space in the valve body, allowing for larger gas inlet and outlet sizes when the valve body height is limited. This improves the gas valve's adjustable range and meets users' wide range of ignition adjustment needs. Attached Figure Description

[0054] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0055] Example 1

[0056] This utility model provides a gas valve that is applied in a gas stove and is connected to the burner of the gas stove through a gas pipeline to control the gas opening degree of each gas ring of the burner.

[0057] Specifically, the gas valve includes a valve body and a shut-off valve located inside the valve body. The valve body has a gas inlet channel and multiple gas outlet channels respectively connected to different gas rings. The gas inlet channel is connected to the shut-off valve through a gas inlet, and each gas outlet channel is connected to the shut-off valve through a corresponding gas outlet. The gas inlet and each gas outlet are located on the side of the shut-off valve, and in the height direction of the shut-off valve, the gas inlet and at least one gas outlet are arranged flush. This structural design, by placing the gas inlet channel of the valve body and the gas inlet of the shut-off valve on the side of the shut-off valve, and arranging the gas inlet and at least one gas outlet of the valve body flush, frees up the height space of the valve body. This allows for a larger size of the gas inlet and each gas outlet when the valve body height is limited, thereby increasing the gas adjustable range of the gas valve. This ensures that when the gas valve is used in gas stoves with limited height dimensions, such as integrated stove products, the gas adjustable range provided by the gas valve can still meet the user's needs.

[0058] More preferably, in order to rationally arrange the connection between the gas inlet and outlet channels when the burner has multiple gas rings, i.e., the gas valve has multiple gas outlet channels corresponding to the gas rings, and to avoid excessive occupation of the circumferential space of the shut-off valve, the number of shut-off valves in a single gas valve is multiple (at least two), and a transmission mechanism is further provided in the gas valve to connect each shut-off valve to the transmission mechanism to achieve synchronous rotation. Simultaneously, the number of gas inlet channels corresponds to the number of shut-off valves, so as to supply gas to the corresponding shut-off valves respectively. Each gas inlet channel is connected to the corresponding shut-off valve through a gas outlet, while each gas outlet channel is connected to the corresponding shut-off valve through a gas inlet. By increasing the number of shut-off valves, and achieving synchronous rotation between them through the transmission mechanism, the number of gas outlet channels on each shut-off valve is reduced while the number of gas outlet channels in the gas valve remains unchanged. This allows for a further increase in the size of the gas outlet of the gas outlet channel and the gas inlet of the gas inlet channel, thereby further improving the gas adjustable range of the gas valve.

[0059] This structural design is particularly suitable for burners with three or more gas rings, and can significantly reduce the number of gas intake channels that need to be set on each octagon.

[0060] Based on the above scheme, this embodiment provides a more preferred structural arrangement of a gas valve, which enables gas supply to a burner with three gas rings (inner ring, middle ring and outer ring) by setting two synchronously rotating valves. The space available for setting the gas inlet and gas outlet is large, which can achieve a large gas adjustable range even when the valve body height is limited.

[0061] Specifically, the structure of the gas valve provided in this embodiment is as follows: Figure 1As shown, the gas valve 100 includes a valve body 1 and a valve stem 2. The valve stem 2 extends inward into the valve body 1 and connects to one of the valves (the second valve 32) to drive the second valve 32 to rotate, which in turn drives the first valve 31 to rotate synchronously via the transmission mechanism 4.

[0062] A microswitch 5 is provided on the upper surface of the valve body 1 to be triggered when the valve stem 2 is rotated, controlling the ignition needle of the burner to ignite. Simultaneously, an air inlet 14 and three air outlets 15 are provided on the side of the valve body 1. The air inlet 14 connects to an external gas pipe, allowing gas to be delivered into the valve body 1. During this process, the gas passes through a solenoid valve 6; only after the solenoid valve 6 is opened can the gas be delivered to the burner via the gas inlet passage. Specifically... Figure 3 As shown, after the gas passes through the solenoid valve 6, it is connected to the first gate 31 and the second gate 32 through the first intake channel 111 and the second intake channel 112 respectively, so as to supply gas to the two gates respectively.

[0063] Specifically, the three gas outlets 15 located on the surface of the valve body 1 of the gas valve 100 are respectively connected to the inner ring, middle ring, and outer ring of the burner. In this embodiment, as... Figure 2 As shown, after the cover 11 of the valve body 1 is hidden, two valves are visible inside the valve body 1, namely the first valve 31 and the second valve 32. The first valve 31 and the second valve 32 rotate synchronously through a gear-driven transmission mechanism 4.

[0064] Among them, such as Figure 3 As shown, the gas outlet passage connected to the inner gas ring of the burner is the first outlet passage 121, the gas outlet passage connected to the middle gas ring of the burner is the second outlet passage 122, and the gas outlet passage connected to the outer gas ring of the burner is the third outlet passage 123. Figure 3 As can be seen, the first air outlet channel 121 is connected to the first closed element 31 on the right, while the second air outlet channel 122 and the third air outlet channel 123 are connected to the second closed element 32 on the left.

[0065] Therefore, when the gas valve 100 provided in this embodiment is applied to a burner with three gas rings (inner ring, middle ring, and outer ring), one gas outlet channel connected to the inner gas ring is connected to one shut-off element (first shut-off element 31), while the two gas outlet channels connected to the middle and outer gas rings are connected to another shut-off element (second shut-off element 32). This reasonable arrangement of connections allows the inner ring to have a relatively larger and more independent adjustable space. Of course, this is only one specific implementation example to clearly illustrate the solution provided by this utility model. In other embodiments, the gas valve 100 can also be applied to four-ring burners or even burners with five or more rings, and the number of shut-off elements of the gas valve 100 can also be set to three or more to meet the actual gas channel requirements of the product.

[0066] Specifically, such as Figure 3 As shown, in the height direction of the first closure 31, the gas inlet 1111 of the first intake channel 111 and the gas outlet 1211 of the first outlet channel 121 are arranged flush. This structural arrangement, by aligning the gas inlet 1111 of the first intake channel 111 and the gas outlet 1211 of the first outlet channel 121 in the height direction of the first closure 31, makes efficient use of the height space of the gas valve 100, allowing for a larger gas outlet height in the first outlet channel 121 connected to the inner ring, thus meeting the wide-range gas adjustment requirements of the inner ring.

[0067] In addition, such as Figure 3 As shown, in the height direction of the second gate 32, the gas inlet 1121 of the second intake channel 112, the gas outlet 1221 of the second outlet channel 122, and the gas outlet 1231 of the third outlet channel 123 are also arranged flush. This structural arrangement, in the height direction of the second gate 32, ensures that the gas inlet 1121 of the second intake channel 112, the gas outlet 1221 of the second outlet channel 122, and the gas outlet 1231 of the third outlet channel 123 are all arranged flush, thus making reasonable use of the height space of the gas valve 100. This allows for an increase in the height dimensions of the gas outlets of both the second outlet channel 122 (connected to the middle ring) and the third outlet channel 123 (connected to the outer ring), meeting the wide-range gas adjustment needs of the middle and outer rings. Although the two gas outlets corresponding to the middle ring and the outer ring are both set to the same shut-off element (second shut-off element 32), the flame of the middle ring and the outer ring is usually turned on or off synchronously during the user's daily flame adjustment operation. Therefore, setting the two gas outlets corresponding to the middle ring and the outer ring to be aligned with the second shut-off element 32 will not affect the flame adjustment accuracy of the two gas rings.

[0068] Further as Figure 3 , Figure 4 and Figure 5As shown, along the rotation direction of the second shut-off valve 32, the gas inlet 1121 of the second intake channel 112, the gas outlet 1221 of the second outlet channel 122, and the gas outlet 1231 of the third outlet channel 123 are arranged sequentially. This ensures that as the gas is gradually opened by rotating the second shut-off valve 32 in the forward direction, the gas inlet 1121 of the second intake channel 112 first connects to the gas outlet 1221 of the corresponding middle ring's second outlet channel 122, and then connects to the gas outlet 1231 of the corresponding outer ring's third outlet channel 123, thus meeting the user's daily ignition adjustment needs. Simultaneously, as the gas is gradually closed by rotating the second shut-off valve 32 in the reverse direction, the gas inlet 1121 of the second intake channel 112 first closes to the gas outlet 1231 of the corresponding outer ring's third outlet channel 123, and then closes to the gas outlet 1221 of the corresponding middle ring's second outlet channel 122, also meeting the user's daily ignition adjustment needs.

[0069] like Figure 2 As shown in this embodiment, Figure 2 and Figure 6 As shown, the transmission mechanism 4 specifically includes a first gear 41, a second gear 42, and a third gear 43. The first gear 41 is mounted on the first stop 31, the third gear 43 is mounted on the second stop 32, and the second gear 42 is positioned between the two stops and rotatably mounted on the valve body 1, meshing with the first gear 41 and the third gear 43 respectively. Compared to other gear transmission configurations, this embodiment, by mounting the second gear 42 on the valve body 1 to mesh with the first gear 41 and the third gear 43 on the two stops respectively, allows the two stops to rotate in the same direction, reducing the design complexity of the gas on / off relationship of the gas valve 100.

[0070] In addition, such as Figure 5 and Figure 7 As shown, the valve body 1 also includes a valve body 12 and a cover plate 13 that are detachably connected. The cover plate 13 is installed upward along the height direction of the valve body 12 at the bottom. Furthermore, the valve body 12 and the cover plate 13, through their relative combination, together form a first air intake channel 111 and a second air intake channel 112. This structural arrangement, specifically through the relative combination of the valve body 12 and the cover plate 13, forms the internal gas intake channel of the valve body 1. This eliminates the size limitations of the holes formed by drilling on the surface of the parts, allowing for a larger gas intake channel size, reduced gas intake resistance, and ensuring stable operation of the gas valve 100, while reducing gas fluctuations during ignition adjustment.

[0071] Therefore, by applying this gas valve 100 to a gas stove, a relatively large gas adjustment range can be provided even when the height of the space below the stovetop, i.e., the internal space of the stove chassis, is limited, thus meeting the user's wide range of flame adjustment needs. This is particularly suitable for the current needs of integrated stove products. By further reducing the height of the gas valve 100 while ensuring the gas adjustment range, more space is provided for installing other kitchen appliances below the stovetop, meeting the growing demand for multifunctional and differentiated integrated stove products.

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.
