[0031] The present utility model provides the following description with reference to the drawings to help a comprehensive understanding of various embodiments of the present utility model as defined by the claims and their equivalents. The description includes various specific details to assist understanding, but these details should be regarded as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the present utility model.

[0032] In the description of the present utility model, with regard to the orientation description, for example, the orientation or positional relationship indicated by up, down, front, back, left, right, etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0033] It should be understood that when an element (for example, the first element) is "connected" to another element (for example, the second element), the element can be directly connected to the other element, or there can be an intermediate element (for example, the third element) between the element and the other element.

[0034] An embodiment of the present utility model provides a multi-functional valve body for a gas stove, as Figure 1 shown, including an air inlet passage, a first air outlet pipe 110, a second air outlet pipe 120, a third air outlet pipe 130, a first bypass pipe 210, a second bypass pipe 220, a third bypass pipe 230, a connection cavity 240, and an electric control valve 330. The electric control valve 330 can be switched to an open state or a closed state according to the input electrical signal, and the first switch 310 and the second switch 320 need to be manually operated by the user to be switched to an open state or a closed state.

[0035] The intake passage is used to communicate with an external gas pipeline. The rear ends of the first outlet pipe 110 and the second outlet pipe 120 are both connected to the intake passage. Therefore, the gas will enter the first outlet pipe 110 and the second outlet pipe 120 through the intake passage. The front end of the first outlet pipe 110 has a first gas outlet 111, and the first gas outlet 111 can output the gas in the first outlet pipe 110. The two ends of the second bypass pipe 220 are respectively connected to the second outlet pipe 120 and the connection cavity 240. The gas in the second outlet pipe 120 can enter the connection cavity 240, and the rear end of the third outlet pipe 130 is connected to the connection cavity 240. The electric control valve 330 has a movable valve head 331. The valve head 331 is located in the connection cavity 240. The rear end of the third outlet pipe 130 is blocked or opened by the valve head 331. When the valve head 331 opens the rear end of the third outlet pipe 130, the gas in the connection cavity 240 can flow to the third outlet pipe 130. When the valve head 331 blocks the rear end of the third outlet pipe 130, the gas in the connection cavity 240 cannot flow from the rear end of the third outlet pipe 130 to the third outlet pipe 130. The front end of the third outlet pipe 130 has a third gas outlet 131, and the third gas outlet 131 can output the gas in the third outlet pipe 130. The first gas outlet 111 is used to supply gas to one of the outer ring mixing cavity and the inner ring mixing cavity, and the third gas outlet 131 is used to supply gas to the other of the outer ring mixing cavity and the inner ring mixing cavity. For example, the first gas outlet 111 is used to supply gas to the outer ring mixing cavity, and the third gas outlet 131 is used to supply gas to the inner ring mixing cavity, or the first gas outlet 111 is used to supply gas to the inner ring mixing cavity, and the third gas outlet 131 is used to supply gas to the outer ring mixing cavity. The outer ring mixing cavity and the inner ring mixing cavity are both arranged in the burner. The mixed gas in the outer ring mixing cavity is used to form an outer ring flame, and the mixed gas in the inner ring mixing cavity is used to form an inner ring flame.

[0036] One end of the third bypass pipe 230 is connected to the third outlet pipe 130. One end of the first bypass pipe 210 is connected to the second outlet pipe 120, and the first bypass pipe 210 is also connected to the third outlet pipe 130. The position where the first bypass pipe 210 is connected to the third outlet pipe 130 is in front of the position where the third bypass pipe 230 is connected to the third outlet pipe 130. Here, the front is relative to the flowing direction of the gas in the third outlet pipe 130. Therefore, the position where the first bypass pipe 210 is connected to the third outlet pipe 130 is closer to the third gas outlet 131.

[0037] The first switch 310 is arranged in the first bypass pipe 210 between the second air outlet pipe 120 and the third air outlet pipe 130. After the first switch 310 is opened, the second air outlet pipe 120 and the third air outlet pipe 130 are communicated through the first bypass pipe 210. After the first switch 310 is closed, the gas in the second air outlet pipe 120 cannot flow to the third air outlet pipe 130 through the first bypass pipe 210, or the first bypass pipe 210 between the second air outlet pipe 120 and the third air outlet pipe 130 is in a closed state, or the first bypass pipe 210 between the second air outlet pipe 120 and the third air outlet pipe 130 is in a conducting state.

[0038] The second switch 320 is arranged in the third air outlet pipe 130 between the first bypass pipe 210 and the third bypass pipe 230. After the second switch 320 is opened, the gas at the rear end of the third air outlet pipe 130 can flow to the third air outlet 131. After the second switch 320 is closed, the gas at the rear end of the third air outlet pipe 130 cannot flow along the third air outlet pipe 130 to the third air outlet 131, or the third air outlet pipe 130 between the first bypass pipe 210 and the third bypass pipe 230 is in a closed state, or the third air outlet pipe 130 between the first bypass pipe 210 and the third bypass pipe 230 is in a conducting state.

[0039] The front end of the second air outlet pipe 120 is closed or forms a second air outlet, and one end of the third bypass pipe 230 far away from the third air outlet pipe 120 is closed or forms a fourth air outlet.

[0040] By switching the on-off state of the electric control valve 330, the first switch 310, the second switch 320, or initially setting the conducting state of the third air outlet pipe 130 and the initial setting of the conducting state of the third air outlet pipe 130, the gas flow direction can be changed to form a variety of different gas path structures. By configuring the front end of the second air outlet pipe 120 to be closed or form a second air outlet and one end of the third bypass pipe 330 far away from the third air outlet pipe 130 to be closed or form a fourth air outlet to form a variety of gas supply states, different firing functions can be realized according to the user's needs. Specifically, the on-off of the outer ring gas path can be controlled, the heat load of the outer ring flame can be adjusted, the on-off of the central gas path can be controlled, and various different firing functions such as central small fire, soup cooking, and stir-frying can be realized. At the same time, in this embodiment, multiple functions are realized through the same valve body, which has stronger versatility, does not require developing a set of valve bodies separately for each function, and also reduces the manufacturing cost.

[0041] In order to further illustrate the present utility model in detail, six specific embodiments will be provided below on the basis of the above embodiments.

[0042] Embodiment 1:

[0043] As Figure 1As shown, the front end of the second gas outlet pipe 120 is closed, and the end of the third bypass pipe 230 away from the third gas outlet pipe 130 is also closed. During use, there are mainly three usage modes: (1) The first switch 310 can be opened, the electric control valve 330 can be closed, and the gas in the second gas outlet pipe 120 sequentially passes through the first bypass pipe 210 and the third gas outlet pipe 130, and finally is output from the third gas outlet 131; (2) The electric control valve 330 and the second switch 320 can be opened, the first switch 310 can be closed, and the gas in the second gas outlet pipe 120 sequentially passes through the second bypass pipe 220, the connection cavity 240 and the third gas outlet pipe 130, and finally is output from the third gas outlet 131; (3) The electric control valve 330, the first switch 310 and the second switch 320 can be opened, and the gas in the second gas outlet pipe 120 can either enter the third gas outlet pipe 130 through the first bypass pipe 210 or enter the third gas outlet pipe 130 through the second bypass pipe 220 and the connection cavity 240, and finally is output from the third gas outlet 131.

[0044] Therefore, this embodiment can supply gas to the outer ring mixing cavity and the inner ring mixing cavity simultaneously to form an outer ring flame and an inner ring flame. Among them, the gas outlet flow rates of the third gas outlet 131 corresponding to the above three usage modes are different, so that the sizes of the outer ring flame or the inner ring flame corresponding to the third gas outlet 131 can be adjusted. Naturally, when the third mode is applied, the firepower of the outer ring flame or the inner ring flame is the largest.

[0045] In this embodiment, the first gas outlet 111 and the third gas outlet 131 generally do not directly output gas outward. Nozzles 101 can be fixed to the first gas outlet 111 and the third gas outlet 131 to eject gas into the outer ring mixing cavity and the inner ring mixing cavity of the burner through the nozzles 101.

[0046] Embodiment 2:

[0047] As Figure 2 shown, the front end of the second gas outlet pipe 120 forms a second gas outlet 121, and the second gas outlet 121 is used to supply gas to the outer ring mixing cavity, the inner ring mixing cavity or the central mixing cavity. The end of the third bypass pipe 230 away from the third gas outlet pipe 130 is closed.

[0048] During use, there are mainly three usage modes: (1) The valve head 331 opens the rear end of the third gas outlet pipe 130, the first switch 310 is closed, and the second switch 320 is opened; (2) The valve head 331 closes the rear end of the third gas outlet pipe 130, and the first switch 310 is opened; (3) The valve head 331 opens the rear end of the third gas outlet pipe 130, and both the first switch 310 and the second switch 320 are opened.

[0049] The above three methods can all make the first gas outlet 111, the second gas outlet 121 and the third gas outlet 131 output gas outward, supply gas to the outer ring mixing chamber and the inner ring mixing chamber simultaneously, so as to form an outer ring flame and an inner ring flame. At the same time, the second gas outlet 121 can increase the gas volume supplied to the outer ring mixing chamber or the inner ring mixing chamber, so that the outer ring fire or the inner ring fire forms a stir-fry mode.

[0050] In this embodiment, nozzles 101 can be fixed to the first gas outlet 111, the second gas outlet 121 and the third gas outlet 131 respectively, so as to inject gas into the outer ring mixing chamber and the inner ring mixing chamber of the burner through the nozzles 101.

[0051] Embodiment 3:

[0052] As Figure 3 shown, the front end of the second gas pipe 120 is closed, and one end of the third bypass pipe 230 far from the third gas pipe 130 forms a fourth gas outlet 231, and the fourth gas outlet 231 is used to supply gas to the central ring mixing chamber of the burner.

[0053] During use, there are mainly two usage methods: (1) The valve head 331 opens the rear end of the third gas pipe 130, the first switch 310 is opened, and the second switch 320 is closed; (2) The valve head 331 opens the rear end of the third gas pipe 130, the first switch 310 is closed, and the second switch 320 is opened.

[0054] The above two methods can both make the first gas outlet 111, the second gas outlet 121 and the fourth gas outlet 231 output gas outward, supply gas to the outer ring mixing chamber, the inner ring mixing chamber and the central mixing chamber simultaneously, so as to form a three-ring fire structure of an outer ring flame, an inner ring flame and a central flame. At the same time, the fourth gas outlet 231 can increase the gas volume supplied to the central mixing chamber, so that the central fire forms a stir-fry mode.

[0055] In this embodiment, nozzles 101 can be fixed to the first gas outlet 111 and the second gas outlet 121 respectively, so as to inject gas into the outer ring mixing chamber and the inner ring mixing chamber of the burner through the nozzles 101. The fourth gas outlet 231 can be connected with a corresponding injection pipeline to supply gas to the central mixing chamber through the injection pipeline.

[0056] Embodiment 4:

[0057] As Figure 4 shown, compared with Embodiment 1, in this embodiment, no first switch is provided in the first bypass pipe 210 between the second gas pipe 120 and the third gas pipe 130, but a blocking wall 340 is provided, so that the first bypass pipe 210 between the second gas pipe 120 and the third gas pipe 130 is initially in a closed state, and the electric control valve 330 can control whether to supply gas to the third gas outlet 131 or not.

[0058] The blocking wall 340 can be integrally formed with the inner wall of the first bypass pipe 210 during casting.

[0059] Embodiment 5:

[0060] As Figure 5 shown, compared with Embodiment 3, in this embodiment, no first switch is provided in the first bypass pipe 210 between the second outlet pipe 120 and the third outlet pipe 130. Instead, the first bypass pipe 210 is made to be through, and the first bypass pipe 210 between the second outlet pipe 120 and the third outlet pipe 130 is in a conducting state. No second switch is provided in the third outlet pipe 130 between the first bypass pipe 210 and the third bypass pipe 230 either. Instead, a blocking wall 340 is provided, such that the third outlet pipe 130 between the first bypass pipe 210 and the third bypass pipe 230 is in a closed state. Thus, the electric control valve 330 can control whether to supply gas to the fourth gas outlet 231 or not.

[0061] The blocking wall 340 can be integrally formed with the inner wall of the third outlet pipe 130 during casting.

[0062] Embodiment 6:

[0063] As Figure 6 shown, compared with Embodiment 2, the first bypass pipe 210 between the second outlet pipe 120 and the third outlet pipe 130 in this embodiment is through, and the first bypass pipe 210 between the second outlet pipe 120 and the third outlet pipe 130 is in a conducting state. The third outlet pipe 130 between the first bypass pipe 210 and the third bypass pipe 230 is through, such that the third outlet pipe 130 between the first bypass pipe 210 and the third bypass pipe 230 is conducting.

[0064] In some embodiments, the front end of the second outlet pipe 120 and the end of the third bypass pipe 330 away from the third outlet pipe 130 can be a closed structure during casting and molding.

[0065] In some embodiments, the second gas outlet 121 and the fourth gas outlet 231 can be formed during casting and molding, or the front end of the closed second outlet pipe 120 and the end of the closed third bypass pipe 330 away from the third outlet pipe 130 can be subjected to post-opening treatment to form the second gas outlet 121 and the fourth gas outlet 231.

[0066] In some embodiments, a second air outlet 121 is formed at the front end of the second air outlet pipe 120, and a fourth air outlet 231 is formed at one end of the third bypass pipe 230 away from the third air outlet pipe 130. A sealing member 400 is detachably fixed to both the second air outlet 121 and the fourth air outlet 231. Since it is detachable, the sealing member 400 can be fixed in the second air outlet 121 and the fourth air outlet 231 to block the second air outlet 121 and the fourth air outlet 231, making the front end of the second air outlet pipe 120 and one end of the third bypass pipe 330 away from the third air outlet pipe 130 a closed structure; the sealing member 400 can also be detached from the second air outlet 121 and the fourth air outlet 231, thereby exposing the second air outlet 121 and the fourth air outlet 231. Therefore, in this embodiment, the front end of the second air outlet pipe 120 can be closed or the second air outlet 121 can be formed as needed by the sealing member 400, and one end of the third bypass pipe 230 away from the third air outlet pipe 120 can also be closed or the fourth air outlet 231 can be formed, making it more flexible in use.

[0067] Further, both the second air outlet 121 and the fourth air outlet 231 can be threaded holes, and the sealing member 400 can be a screw adapted thereto for easy installation and disassembly.

[0068] In some embodiments, a fifth air outlet is formed at one end of the first bypass pipe 210 away from the second air outlet pipe 120, and the gas in the second air outlet pipe 120 can also be output through the fifth air outlet to further increase the function of the entire valve body.

[0069] Further, a sealing member is detachably fixed to the fifth air outlet. Since it is detachable, the sealing member can be fixed in the fifth air outlet to block the fifth air outlet, making one end of the first bypass pipe 210 away from the second air outlet pipe 120 a closed structure; the sealing member can also be detached from the fifth air outlet, thereby exposing the fifth air outlet. Therefore, in this embodiment, one end of the first bypass pipe 210 away from the second air outlet pipe 120 can be closed or the fifth air outlet can be formed as needed by the sealing member, making it more flexible in use.

[0070] Further, the fifth air outlet can be a threaded hole, and the sealing member can be a screw adapted thereto for easy installation and disassembly.

[0071] In some embodiments, the second bypass pipe 220 can be obliquely arranged, which facilitates opening a hole in the inner wall of the connection cavity 240 to form the second bypass pipe 220 and is convenient for product processing and forming.

[0072] In some embodiments, the first air outlet pipe 110, the second air outlet pipe 120, and the third air outlet pipe 130 can be parallel to each other, and both the first bypass pipe 210 and the third bypass pipe 230 can be perpendicular to the third air outlet pipe 130 for easy gas path layout.

[0073] An embodiment of the present utility model further provides a gas stove, which includes a burner and the multi-functional valve body of the gas stove in any of the above embodiments. For the specific description of the multi-functional valve body of the gas stove, reference can be made to the above embodiments and will not be elaborated here.

[0074] In some embodiments, the burner has an outer ring mixing chamber and an inner ring mixing chamber. The mixed gases in the outer ring mixing chamber and the inner ring mixing chamber are respectively ejected through outer ring fire holes and inner ring fire holes, and the ejected gases can form an outer ring flame and an inner ring flame respectively after being ignited.

[0075] When the front end of the second air outlet pipe forms a second air outlet, and the second air outlet is used to supply gas to one of the outer ring mixing chamber and the inner ring mixing chamber, and one end of the third bypass pipe away from the third air outlet pipe is closed, the second air outlet can increase the gas supply amount to the outer ring mixing chamber or the inner ring mixing chamber, so that the outer ring fire or the inner ring fire forms a stir-fry mode.

[0076] In other embodiments, the burner has an outer ring mixing chamber, an inner ring mixing chamber and a central mixing chamber. The mixed gases in the outer ring mixing chamber, the inner ring mixing chamber and the central mixing chamber are respectively ejected through outer ring fire holes, inner ring fire holes and central fire holes, and the ejected gases can form an outer ring flame, an inner ring flame and a central flame respectively after being ignited.

[0077] When the front end of the second air outlet pipe is closed, and one end of the third bypass pipe away from the third air outlet pipe forms a fourth air outlet, and the fourth air outlet is used to supply gas to the central ring mixing chamber of the burner, the fourth air outlet can increase the gas supply amount to the central mixing chamber, so that the central fire forms a stir-fry mode.

[0078] The terms and words used in the above description and claims are not limited to their literal meanings, but are only used by the applicant to enable a clear and consistent understanding of the present utility model. Therefore, those skilled in the art should clearly understand that the above descriptions of various embodiments of the present utility model are only for illustration, rather than for limiting the present utility model as defined by the appended claims and their equivalents.
