Description

Technical Field

[0001] This invention relates to a gas stove. Background Technology

[0002] In existing gas stoves, the operator opens the solenoid valve to allow gas to flow into the gas pipeline. Gas then enters the stove through the intake pipe and passes through a proportional valve that controls the gas flow rate, regulating the intake volume into the outer and inner rings. Finally, the gas flows into the outer and inner rings respectively, ultimately generating an electric spark. However, this type of gas stove, which relies on a proportional valve to regulate the intake volume of the outer and inner rings, prevents the operator from independently, separately, and simultaneously controlling the inner and outer rings of the gas pipeline. Furthermore, the internal structure of the gas pipeline in existing technologies is quite complex, and the manufacturing process is rather cumbersome.

[0003] Therefore, the regulation methods for gas pipelines urgently need to be addressed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art in which gas pipelines cannot be controlled independently and simultaneously, and to provide a gas stove.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A gas stove, comprising:

[0007] Main valve seat;

[0008] The mixing chamber is located inside the main valve seat. The mixing chamber includes an outer ring mixing chamber and an inner ring mixing chamber, which are connected by a connecting pipe.

[0009] An intake pipe, wherein the outer ring mixing chamber and / or the inner ring mixing chamber are connected to the intake pipe;

[0010] A proportional valve, comprising an outer ring proportional valve and an inner ring proportional valve, wherein the outer ring proportional valve and the inner ring proportional valve are respectively disposed inside the outer ring mixing chamber and the inner ring mixing chamber, and each of the outer ring proportional valve and the inner ring proportional valve divides its respective mixing chamber into two chambers. The air outlet of the outer ring mixing chamber and the air outlet of the inner ring mixing chamber are respectively disposed in the two different chambers of the outer ring mixing chamber and the inner ring mixing chamber.

[0011] The intake pipe and the connecting pipe are directly connected. By connecting the outer ring mixing chamber and the inner ring mixing chamber, and also directly connecting the intake pipe and the connecting pipe, the amount of gas discharged from the outlet of each mixing chamber is regulated by the proportional valves inside the inner and outer ring mixing chambers. Furthermore, the outlet of each mixing chamber and the intake pipe are located in two different chambers of the proportional valve, achieving separate regulation of the inner and outer rings. This avoids gas mixing within the gas stove, improves cooking efficiency, and also enhances the sealing of the gas entering the inner ring mixing chamber to some extent. Simultaneously, this internal design of the gas stove makes the overall internal structure compact, facilitating injection molding.

[0012] Preferably, the proportional valve is provided with a sealing part.

[0013] By adding a sealing part to the proportional valve, the sealing performance of the gas flow in the inner and outer chambers of each mixing chamber is further enhanced, avoiding problems such as gas leakage.

[0014] Preferably, the outer ring proportional valve divides the outer ring mixing chamber into an outer ring proportional valve outer cavity and an outer ring proportional valve inner cavity, the outer ring proportional valve outer cavity and the outer ring proportional valve inner cavity are arranged in the height direction of the gas stove, and the outer ring proportional valve outer cavity is located above the outer ring proportional valve inner cavity.

[0015] The inner ring proportional valve divides the inner ring mixing chamber into an outer chamber and an inner chamber. The outer chamber and the inner chamber are arranged in the height direction of the gas stove, and the outer chamber is located above the inner chamber.

[0016] The outer ring proportional valve and the inner ring proportional valve extend along the height of the gas stove and adjust the gas intake of different chambers in the mixing chamber by moving up and down.

[0017] This structural design effectively controls the gas intake volume in both the inner and outer chambers of the mixing chamber, while simplifying the structure and operation mechanism of the proportional valve, thus improving the ease of operation and efficiency of the gas stove.

[0018] Preferably, the intake pipe is connected to the outer cavity of the outer ring proportional valve;

[0019] The outer cavity of the outer ring proportional valve and the outer cavity of the inner ring proportional valve are connected by the connecting pipe.

[0020] The above-mentioned structure ensures the normal flow of gas in the outer and inner ring mixing chambers, enabling individual control of the gas stove. Furthermore, this design makes the gas stove's structure simple and compact, and further enhances the sealing of the gas entering the inner ring mixing chamber.

[0021] Preferably, the gas stove further includes an electromagnetic valve, which serves as a master switch for controlling the gas entering the gas stove, and the electromagnetic valve is located near the gas inlet of the gas inlet pipe.

[0022] The solenoid valve includes a first solenoid valve and a second solenoid valve, which are arranged sequentially along the gas intake direction.

[0023] The above-mentioned structural design further enhances the sealing performance of gas entering the gas stove.

[0024] Preferably, the movement direction of the solenoid valve and / or the proportional valve is the same as the input direction of the gas entering the gas stove.

[0025] This structural design effectively enhances the sealing performance of the solenoid valve and / or proportional valve in controlling the gas flow into the gas stove.

[0026] Preferably, the intake pipe is connected to the inner cavity of the outer ring proportional valve;

[0027] The inner cavity of the outer ring proportional valve and the outer cavity of the inner ring proportional valve are connected by the connecting pipe.

[0028] The above-mentioned structure ensures the normal flow of gas in the outer and inner ring mixing chambers, enabling individual control of the gas stove. Furthermore, this design makes the gas stove's structure simple and compact, and further enhances the sealing of the gas entering the inner ring mixing chamber.

[0029] Preferably, the intake pipe is connected to the inner cavity of the outer ring proportional valve;

[0030] The inner cavity of the outer ring proportional valve and the inner cavity of the inner ring proportional valve are connected by the connecting pipe.

[0031] The above-mentioned structure ensures the normal flow of gas in the outer and inner ring mixing chambers, enabling individual control of the gas stove. Furthermore, this design makes the gas stove's structure simple and compact, and further enhances the sealing of the gas entering the inner ring mixing chamber.

[0032] Preferably, the gas stove further includes an outer ring solenoid valve, which is disposed on an outer ring connector that communicates with the outer ring mixing chamber.

[0033] By adopting the above-mentioned structural form, the entry of gas into the outer ring joint is further controlled, and the sealing performance of gas passage into the outer ring joint is further enhanced.

[0034] A method for controlling a gas stove, comprising using a temperature measuring module to measure the temperature of the heated components on the gas stove as described above, the method comprising the following steps:

[0035] S1. The temperature of the heated component is measured at different locations using the temperature measuring module;

[0036] S2. Adjust the gas stove based on the measured temperature results;

[0037] If the temperature at the outer ring burner cap of the heated component is greater than the temperature at the inner ring burner cap, then the outer ring proportional valve is adjusted to reduce the amount of gas received by the outer ring burner cap, and the inner ring proportional valve is adjusted to increase the amount of gas received by the inner ring burner cap.

[0038] If the temperature at the outer ring burner cap of the heated component is lower than the temperature at the inner ring burner cap, then the outer ring proportional valve is adjusted to increase the amount of gas received by the outer ring burner cap, and the inner ring proportional valve is adjusted to decrease the amount of gas received by the inner ring burner cap.

[0039] By adopting the above-mentioned control method, the convenience of temperature detection of the heating element is improved, making it easier to control the gas stove according to the different heating degrees of different parts of the heating element, achieving uniform heating of the heating element, and enabling targeted temperature control of different positions of the heating element, thus improving the efficiency of temperature adjustment of the heating element.

[0040] The positive and progressive effects of this invention are as follows:

[0041] 1. The gas stove described above connects the outer and inner ring mixing chambers, with the inlet and connecting pipes also directly connected. The gas flow from the outlet of each mixing chamber is regulated by a proportional valve within both chambers. Furthermore, the outlet and inlet pipe of each mixing chamber are located in two different chambers of the proportional valve, achieving separate control of the inner and outer rings. This avoids gas sharing within the stove, preventing interference between the inner and outer rings and improving cooking efficiency. This design also enhances the sealing of the gas flow into the inner ring mixing chamber. Simultaneously, this internal design results in a compact internal structure, saving horizontal space. The two mixing chambers can share a single sealing plate, facilitating injection molding and assembly.

[0042] 2. By adopting the above-mentioned control method, the convenience of temperature detection of the heating element is improved, making it easier to control the gas stove according to the different heating degrees of different parts of the heating element, realizing uniform heating of the heating element, and allowing for targeted temperature control of different positions of the heating element, thus improving the efficiency of temperature adjustment of the heating element.

[0078]

Example 1

[0079] like Figures 1-2 As shown in this embodiment 1, a gas stove 100 is disclosed, which includes a main valve seat 11 and an air inlet pipe 14.

[0080] In this embodiment, the main valve seat 11 and the intake pipe 14 are connected, and the intake pipe 14 is used to introduce gas into the interior of the main valve seat 11. The interior of the main valve seat 11 includes a mixing chamber 12, which includes an outer ring mixing chamber 121 and an inner ring mixing chamber 122. In this embodiment, the outer ring mixing chamber 121 and the inner ring mixing chamber 122 are arranged side by side inside the main valve seat 11, and the outer ring mixing chamber 121 and the inner ring mixing chamber 122 are connected by a connecting pipe 123.

[0081] In this embodiment, the intake pipe 14 is connected to the outer ring mixing chamber 121 to allow the introduction of fuel gas. In other embodiments, the intake pipe 14 is connected to the inner ring mixing chamber 122 to allow the introduction of fuel gas; or, the intake pipe 14 is connected to both the outer ring mixing chamber 121 and the inner ring mixing chamber 122 to allow the introduction of fuel gas. The connection method between the mixing chamber 12 and the intake pipe 14 can be configured as needed, and all are within the protection scope of this application.

[0082] In this embodiment, the outer ring mixing chamber 121 and the air intake pipe 14 are connected to realize the introduction of gas. In subsequent embodiments, the structure of the outer ring mixing chamber 121 and the air intake pipe 14 being connected is also adopted, and the specific details will not be repeated.

[0083] Furthermore, the gas stove 100 also includes a proportional valve 13, which comprises an outer ring proportional valve 131 and an inner ring proportional valve 132. The outer ring proportional valve 131 and the inner ring proportional valve 132 are respectively disposed inside the outer ring mixing chamber 121 and the inner ring mixing chamber 122, and each of the outer ring proportional valve 131 and the inner ring proportional valve 132 divides its respective mixing chamber 12 into two different chambers. The proportional valve 13 is used to regulate the amount of gas entering from one chamber to another. At the same time, the gas outlet of the outer ring mixing chamber 121 and the gas outlet of the inner ring mixing chamber 122 are respectively disposed in the two different chambers of the outer ring mixing chamber 121 and the inner ring mixing chamber 122, and the gas inlet pipe 14 is directly connected to the connecting pipe 123.

[0084] In other words, after the gas enters one of the chambers of the outer ring mixing chamber 121 from the intake pipe 14, it can only enter the chamber where the outlet of the outer ring mixing chamber 121 is located through the regulation of the outer ring proportional valve 131, and then be discharged from the outlet of the outer ring mixing chamber 121; or after the gas enters one of the chambers of the outer ring mixing chamber 121 from the intake pipe 14, it can enter one of the chambers of the inner ring mixing chamber 122 through the connecting pipe 123 that connects the outer ring mixing chamber 121 and the inner ring mixing chamber 122, and then enter the chamber where the outlet of the inner ring mixing chamber 122 is located through the regulation of the inner ring proportional valve 132, and finally be discharged from the outlet of the inner ring mixing chamber 122.

[0085] In this embodiment, the aforementioned structural form enables separate control of the inner and outer rings, preventing the gas from sharing gas within the gas stove 100 and causing mutual interference between the inner and outer rings. This improves the cooking efficiency of the gas stove 100, and this arrangement also enhances the sealing of the gas entering the inner ring mixing chamber 122 to some extent. Furthermore, this internal design of the gas stove 100 makes its overall internal structure compact, saving horizontal space. The two mixing chambers can share a single sealing plate, facilitating injection molding and assembly.

[0086] Preferably, as a preferred embodiment of this invention, a sealing part 133 is provided on the proportional valve 13, which can further enhance the sealing of the gas flow in the inner and outer cavities of the respective mixing chambers 12 and avoid problems such as gas leakage.

[0087] Preferably, in a preferred embodiment of this invention, the outer ring proportional valve 131 divides the outer ring mixing chamber 121 into an outer ring proportional valve outer cavity 1211 and an outer ring proportional valve inner cavity 1212. The outer ring proportional valve outer cavity 1211 and the outer ring proportional valve inner cavity 1212 are arranged in the height direction of the gas stove 100, and the outer ring proportional valve outer cavity 1211 is located above the outer ring proportional valve inner cavity 1212. The inner ring proportional valve 132 divides the inner ring mixing chamber 122 into an inner ring proportional valve outer cavity 1221 and an inner ring proportional valve inner cavity 1222. The inner ring proportional valve outer cavity 1221 and the inner ring proportional valve inner cavity 1222 are arranged in the height direction of the gas stove 100, and the inner ring proportional valve outer cavity 1221 is located above the inner ring proportional valve inner cavity 1222.

[0088] Furthermore, the outer ring proportional valve 131 and the inner ring proportional valve 132 extend in the height direction of the gas stove 100, and each adjusts the gas intake volume of different chambers in the mixing chamber 12 by moving up and down.

[0089] In this embodiment, this structural form effectively controls the gas intake of the inner and outer chambers of the respective mixing chambers 12, while simplifying the structure and operation mechanism of the proportional valve 13, thereby improving the ease of operation and efficiency of the gas stove 100.

[0090] Furthermore, in this embodiment, the outer ring proportional valve 131 and the inner ring proportional valve 132 are arranged in parallel, which makes it convenient for the operator to adjust the outer ring proportional valve 131 and the inner ring proportional valve 132 respectively. At the same time, this arrangement also makes the internal structure of the gas stove 100 compact.

[0091] Preferably, as a preferred embodiment of this embodiment, the intake pipe 14 and the outer ring proportional valve outer cavity 1211 are connected, and the outer ring proportional valve outer cavity 1211 and the inner ring proportional valve outer cavity 1221 are connected through the connecting pipe 123.

[0092] By adopting the above-mentioned structural form, the normal flow of gas in the outer ring mixing chamber 121 and the inner ring mixing chamber 122 is ensured, and the gas stove 100 can be individually controlled. In addition, this setting also makes the structure of the gas stove 100 simple and compact, and further enhances the sealing of the gas entering the inner ring mixing chamber 122.

[0093] Preferably, as a preferred embodiment of this invention, the gas stove 100 further includes a connector 16, and the injector tube 16 includes an outer ring connector 161 and an inner ring connector 162. The outer ring connector 161 is connected to the outer ring mixing chamber 121 through the gas outlet of the outer ring mixing chamber 121, and the inner ring connector 162 is connected to the inner ring mixing chamber 122 through the gas outlet of the inner ring mixing chamber 122. In this way, the gas is introduced from the gas inlet pipe 14 into the mixing chamber 12, and finally "released" from the connector 16, thus preparing for the subsequent ignition of the electric spark.

[0094] Therefore, in this embodiment, the outlet of the outer ring mixing chamber 121 is located on the inner cavity 1212 of the outer ring proportional valve, that is, the gas enters the outer ring connector 161 from the inner cavity 1212 of the outer ring proportional valve through the outlet of the outer ring mixing chamber 121; the outlet of the inner ring mixing chamber 122 is located on the inner cavity 1222 of the inner ring proportional valve, that is, the gas enters the inner ring connector 162 from the inner cavity 1222 of the inner ring proportional valve through the outlet of the inner ring mixing chamber 122.

[0095]

Example 2

[0096] like Figure 3 As shown, this embodiment discloses another gas stove 100. The structures of Embodiment 1 and Embodiment 2 are basically the same. The difference between Embodiment 1 and Embodiment 2 is that:

[0097] The gas stove 100 also includes a solenoid valve 15, which is located near the gas inlet of the gas inlet pipe 14. The solenoid valve 15 serves as the main switch for controlling the gas to enter the gas stove 100 from the gas inlet pipe 14.

[0098] The solenoid valve 15 includes a first solenoid valve 151 and a second solenoid valve 152. The first solenoid valve 151 and the second solenoid valve 152 are arranged sequentially along the gas intake direction. Specifically, the gas enters from the gas intake pipe 14 and passes through the first solenoid valve 151 and the second solenoid valve 152 in sequence. The second solenoid valve 152 is located close to the outer ring mixing chamber 121, which can further enhance the sealing of the gas entering the gas stove 100.

[0099] Preferably, in a preferred embodiment of this invention, the movement direction of the solenoid valve 15 and / or the proportional valve 13 is the same as the input direction of the gas entering the gas stove 100.

[0100] Specifically, in this embodiment, the operator "activates" the solenoid valve 15 by pressing it, causing it to move up and down, thus allowing gas to smoothly enter the gas stove 100. The proportional valve 13 also moves up and down within the mixing chamber 12 to regulate the amount of gas entering the two different chambers. Therefore, the gas enters the gas stove 100 through these operational methods, allowing it to flow vertically. This structural design effectively enhances the sealing performance of the solenoid valve 15 and / or the proportional valve 13 in controlling the gas flow into the gas stove 100.

[0101]

Example 3

[0102] like Figures 4-5 As shown, this embodiment discloses another gas stove 100. The structures of Embodiment 1 and Embodiment 3 are basically the same, and the difference between Embodiment 1 and Embodiment 3 is that:

[0103] The intake pipe 14 is connected to the inner cavity 1212 of the outer ring proportional valve, and the inner cavity 1212 of the outer ring proportional valve and the outer cavity 1221 of the inner ring proportional valve are connected through the connecting pipe 123.

[0104] In this embodiment, the above-described structure ensures the normal flow of gas in the outer ring mixing chamber 121 and the inner ring mixing chamber 122, enabling individual control of the gas stove 100. Furthermore, this design makes the structure of the gas stove 100 simple and compact, and further enhances the sealing of the gas entering the inner ring mixing chamber 122.

[0105] Therefore, in this embodiment, the outlet of the outer ring mixing chamber 121 is located on the outer ring proportional valve outer cavity 1211, that is, the gas enters the outer ring connector 161 from the outer ring proportional valve outer cavity 1211 through the outlet of the outer ring mixing chamber 121; the outlet of the inner ring mixing chamber 122 is located on the inner ring proportional valve inner cavity 1222, that is, the gas enters the inner ring connector 162 from the inner ring proportional valve inner cavity 1222 through the outlet of the inner ring mixing chamber 122.

[0106]

Example 4

[0107] like Figures 6-7 As shown, this embodiment discloses another gas stove 100. The structures of Embodiment 1 and Embodiment 4 are basically the same, and the difference between Embodiment 1 and Embodiment 4 is that:

[0108] The intake pipe is connected to the inner cavity 1212 of the outer ring proportional valve, and the inner cavity 1212 of the outer ring proportional valve and the inner cavity 1222 of the inner ring proportional valve are connected through the connecting pipe 123.

[0109] In this embodiment, the above-described structure ensures the normal flow of gas in the outer ring mixing chamber 121 and the inner ring mixing chamber 122, enabling individual control of the gas stove 100. Furthermore, this design makes the structure of the gas stove 100 simple and compact, and further enhances the sealing of the gas entering the inner ring mixing chamber 122.

[0110] Therefore, in this embodiment, the outlet of the outer ring mixing chamber 121 is located on the outer ring proportional valve outer cavity 1211, that is, the gas enters the outer ring connector 161 from the outer ring proportional valve outer cavity 1211 through the outlet of the outer ring mixing chamber 121; the outlet of the inner ring mixing chamber 122 is located on the inner ring proportional valve outer cavity 1221, that is, the gas enters the inner ring connector 162 from the inner ring proportional valve outer cavity 1221 through the outlet of the inner ring mixing chamber 122.

[0111] Preferably, as a preferred embodiment of this invention, the gas stove 100 further includes an outer ring solenoid valve 153, which is disposed on an outer ring connector 161 that communicates with the outer ring mixing chamber 121.

[0112] In this embodiment, the above-described structural form further controls the entry of gas into the outer ring connector 161 and further enhances the sealing performance of the gas passage through the outer ring connector 161. [Embodiment 5]

[0113] like Figures 8-9 As shown, this embodiment discloses a method for controlling a gas stove 100. A temperature measuring module 200 is used to measure the temperature of the heating element 300 on any one of the gas stoves 100 in embodiments 1-4. A burner cap is provided below the heating element 300 at the positions corresponding to the outer ring and inner ring, namely an outer ring burner cap and an inner ring burner cap. An ignition needle is provided above the burner cap. When the gas is "released", the ignition needle will be ignited to heat the heating element 300.

[0114] Therefore, the control method includes the following steps:

[0115] S1. Temperature measurement is performed at different locations of the heated component 300 using the temperature measurement module 200;

[0116] S2. The measured temperature results are used to adjust the gas stove 100.

[0117] Step S2 includes the following cases:

[0118] If the temperature at the outer ring burner cap of the heated component 300 is greater than the temperature at the inner ring burner cap, then adjust the outer ring proportional valve to reduce the amount of gas received by the outer ring burner cap, and adjust the inner ring proportional valve to increase the amount of gas received by the inner ring burner cap.

[0119] If the temperature at the outer ring burner cap of the heated component 300 is lower than the temperature at the inner ring burner cap, then the outer ring proportional valve is adjusted to increase the amount of gas received by the outer ring burner cap, and the inner ring proportional valve is adjusted to decrease the amount of gas received by the inner ring burner cap.

[0120] In this embodiment, by adopting the above-mentioned control method, the convenience of temperature detection of the heating element 300 is improved, and the gas stove 100 can be controlled according to the different heating degrees of each part of the heating element 300, so as to achieve uniform heating of the heating element 300. Furthermore, the temperature of different positions of the heating element 300 can be controlled in a targeted manner, thereby improving the efficiency of temperature adjustment of the heating element 300.

[0121] Preferably, in a preferred embodiment of this invention, in step S1, the temperature measuring module 200 is located above the heated component 300, that is, the temperature measuring module 200 is set on the range hood above the heated component 300. Preferably, the temperature measuring module 200 is set directly above the heated component 300.

[0122] In this embodiment, by employing the above-described control method and positioning the temperature measuring module 200 in this manner, it is easier for the temperature measuring module 200 to measure the temperature of the heated component 300, and the accuracy of the temperature measurement results is also improved. In other embodiments, the specific structural form and positional relationship of the heated component 300 can be set as needed, all of which fall within the protection scope of this application.
