Description

Technical Field

[0001] The utility model relates to the technical field of gas stove accessories, in particular to a gas stove control valve component. Background Art

[0002] In the design of traditional gas stoves, the flexibility and accuracy of firepower adjustment is one of the key factors affecting the cooking effect. A gas stove usually includes at least one burner, which is provided with an inner ring and an outer ring, which can produce flames of different intensities to meet different cooking needs. For example, the inner ring firepower is usually used for low-calorie cooking needs, such as soup or slow cooking; while the outer ring firepower is used for cooking methods that require high heat, such as stir-frying. Normally, when both the inner and outer rings are ventilated, it is the normal cooking mode; while the stir-frying mode increases the ventilation volume of the outer ring for a short period of time under the normal mode; the soup making mode is to turn on the high fire for a period of time, and then completely close the outer ring and only turn on the inner ring firepower for low heat and slow cooking.

[0003] In the existing technology, the design of gas stoves often cannot accurately control the firepower of the inner ring and the outer ring separately. This means that when the user only needs to use the soup-making mode, the existing technology may not be able to completely turn off the outer ring firepower while keeping the inner ring firepower running stably, resulting in energy waste and unsatisfactory cooking results.

[0004] In addition, although some products have stir-fry mode, their stir-fry structure is often complicated, such as adding an additional stir-fry fire ring (such as CN212157281U), or adding an additional stir-fry gas path, etc. Such a structure has a high manufacturing cost and is troublesome to assemble.

[0005] Therefore, it is necessary to further improve and perfect the prior art to overcome these deficiencies, and the present invention is made based on this situation. Utility Model Content

[0009] In order to further solve the technical problem to be solved by the utility model, in a gas stove control valve assembly provided by the utility model, the solenoid valve is a steady-state valve, and a valve body installation cavity is provided between the first channel and the second channel to connect the two and for installing the solenoid valve.

[0010] In order to further solve the technical problem to be solved by the utility model, in a gas stove control valve assembly provided by the utility model, the solenoid valve is connected to a control circuit board, and a soup-making control button is provided on the control circuit board.

[0012] In order to further solve the technical problem to be solved by the utility model, in a gas stove control valve assembly provided by the utility model, a throttling installation cavity is provided between the first channel and the second channel, which connects the two and is connected in parallel with the valve body installation cavity. A throttling member is provided in the throttling installation cavity, and a throttling channel is provided in the throttling member. The two ends of the throttling channel are wide and the middle is narrow. One end of the throttling channel is connected to the upstream of the solenoid valve, and the other end of the throttling channel is connected to the downstream of the solenoid valve.

[0013] In order to further solve the technical problem to be solved by the utility model, in a gas stove control valve assembly provided by the utility model, the solenoid valve is connected to a control circuit board, and a stir-fry control button is provided on the control circuit board.

[0014] In order to further solve the technical problem to be solved by the utility model, in a gas stove control valve assembly provided by the utility model, the throttling channel includes a gradually shrinking first tapered hole, a throttling hole, and a gradually expanding second tapered hole in sequence along the flow direction.

[0015] In order to further solve the technical problem to be solved by the utility model, in a gas stove control valve assembly provided by the utility model, the proportion of the cross section of the throttle hole and the cross section of the first channel is 10% to 20%.

When the steady-state valve assembly is opened, the outer ring air supply pipeline is unobstructed, and both the inner and outer fire rings can burn, forming a high-fire mode. Conversely, when the steady-state valve assembly is closed, the outer ring air supply pipeline is closed, and only the inner fire ring remains burning, switching to a low-fire mode. This conversion from high fire to low fire not only simulates the traditional soup-making cooking process, but also makes this process simple and easy through the valve body design of the utility model. Users can achieve precise control of firepower through simple operations. In addition, the steady-state valve assembly is detachable, which is convenient for disassembly and maintenance, and helps to reduce costs.

Although this design makes it impossible to completely close the outer ring air supply pipe, it solves the need for rapid switching between different cooking modes. The normally open state of the throttling channel ensures that the outer fire ring can work stably at the rated load even in the non-stir-fry mode, and the switch of the solenoid valve controls whether to enter the stir-fry mode. This flexibility greatly enriches the cooking possibilities. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] Embodiment 1:

[0028] like Figures 1 to 3 The embodiment 1 of the utility model is shown, which is a gas stove control valve assembly. The main advantage of the valve body is that it has a soup-making mode. The valve body includes a plug valve 1, and the plug valve 1 is provided with an inner ring gas supply pipeline 11 and an outer ring gas supply pipeline 12. The two pipelines are responsible for supplying gas to the inner and outer fire rings of the burner respectively. When the plug valve 1 is opened, the inner and outer ring gas supply pipelines can both be ventilated smoothly, thereby providing flexible firepower adjustment for cooking.

[0029] The other end of the inner ring air supply pipeline 11 is provided with an inner fire ring nozzle 2 for connecting to the inner fire ring of the burner, and the other end of the outer ring air supply pipeline 12 is provided with an outer fire ring nozzle 3 for connecting to the outer fire ring of the burner.

[0030] The key innovation of the utility model is that a detachable steady-state valve assembly 4 is provided between the outer ring air supply pipeline 12 and the outer fire ring nozzle 3. The design of the steady-state valve assembly 4 allows the user to flexibly control the on and off of the outer ring air supply according to cooking needs. When the steady-state valve assembly 4 is opened, the outer ring air supply pipeline 12 is unobstructed, and both the inner and outer fire rings can burn, forming a high-fire mode. Conversely, when the steady-state valve assembly 4 is closed, the outer ring air supply pipeline 12 is closed, and only the inner fire ring keeps burning, turning to a low-fire mode.

[0031] The traditional cooking method of making soup requires the chef to accurately control the heat to ensure that the soup can boil quickly and simmer slowly, so as to fully extract the essence of the ingredients. The valve body design of this embodiment is designed to meet this cooking requirement.

[0032] When the user selects the soup-making mode, the high-fire state will be started first. In this state, the steady-state valve assembly 4 is in the open position, and the inner ring air supply pipe 11 and the outer ring air supply pipe 12 simultaneously deliver gas to the inner fire ring and the outer fire ring of the burner. This design makes the flame strong and concentrated, quickly heating the water in the pot to boiling, and providing sufficient heat for the initial stage of making soup. As time goes by, when the water in the pot has boiled and the ingredients begin to release aroma and nutrition, the steady-state valve assembly 4 will automatically close and switch the firepower of the gas stove from high-fire mode to low-fire mode. In this mode, the outer ring air supply pipe 12 is cut off, and only the inner ring air supply pipe 11 continues to deliver gas to the inner fire ring. This method of slow cooking over low heat allows the soup to continue to stew under a gentle heat, and the essence of the ingredients can be fully integrated into the soup.

[0033] This switching from high heat to low heat not only simulates the traditional cooking process of making soup, but also makes the process simple and easy through the valve body design of this embodiment. The user can achieve precise control of the firepower through simple operations.

[0034] It is worth noting that the steady-state valve assembly 4 is detachable, which is convenient for disassembly and maintenance, and is conducive to reducing costs. Specifically, this modular design improves the service life and reliability of the product by simplifying the maintenance and repair process. First, the steady-state valve assembly 4 is designed to be detachable, which is convenient for cleaning and maintenance. Secondly, this detachable design can also facilitate the replacement of damaged parts. If there is a problem with the steady-state valve assembly 4, the user or maintenance personnel can directly replace this one part without replacing the entire gas stove. This can not only avoid unnecessary waste, but also greatly reduce maintenance costs. In addition, this design also helps to improve the environmental friendliness of the product. When the steady-state valve assembly 4 needs to be replaced, the old parts can be recycled and reused or properly disposed of, instead of the entire gas stove being discarded, thereby reducing the generation of waste.

[0035] More specifically, the steady-state valve assembly 4 includes a connecting pipe 41, in which is provided a first channel 411 that is docked with the outer ring air supply pipe 12 (the two can be detachably docked), a second channel 412 that is docked with the outer fire ring nozzle 3 (the two can be detachably docked), and a solenoid valve 42 that is provided between the first channel 411 and the second channel 412 and is used to control the on and off of the two.

[0036] More specifically, the solenoid valve 42 is connected to a control circuit board, and a soup-making control button is provided on the control circuit board. The control circuit board receives instructions from the user, that is, the soup-making program is started by pressing the soup-making control button. Once the user presses the soup-making control button, the control circuit board starts to execute the preset soup-making program, first starting the steady-state valve assembly 4, allowing the inner fire ring and the outer fire ring to burn at the same time, and quickly boiling the soup with a high fire; then, at an appropriate time point, the steady-state valve assembly 4 is closed, and only the gas supply of the inner fire ring is retained, so that the soup is slowly stewed over a low fire, allowing the soup to be slowly boiled under a gentle fire, releasing the deepest deliciousness.

[0037] More specifically, the solenoid valve 42 is a steady-state valve, which is not only easy to install but also highly reliable. A valve body installation cavity 413 is designed between the first channel 411 and the second channel 412 of the connecting pipe 41 to connect the two, for the solenoid valve 42 to be installed and fixed, thereby ensuring that the solenoid valve 42 can stably control the flow of gas.

[0038] In addition, the angle A between the inner ring air supply pipe 11 and the outer ring air supply pipe 12 provides necessary space for the installation of the steady-state valve assembly 4. The design of this angle avoids interference from other components, so that the steady-state valve assembly 4 can find a suitable installation position between the outer ring air supply pipe 12 and the outer fire ring nozzle 3, ensuring the compactness and efficiency of the entire system.

[0039] Embodiment 2:

[0040] like Figure 4 , Figure 5 The second embodiment of the utility model shown is different from the first embodiment described above in that the main advantage of the valve body is that a stir-fry mode is added to the gas stove. Specifically, a throttling installation cavity 414 is provided between the first channel 411 and the second channel 412, which is connected to the two channels and is parallel to the valve body installation cavity 413, and a throttling member 43 is provided in the throttling installation cavity 414. A throttling channel 431 is provided in the throttling member 43, and the two ends of the throttling channel 431 are wide and the middle is narrow. This structure makes the gas encounter a certain resistance when passing through, thereby realizing the control of the flow rate. One end of the throttling channel 431 is connected to the upstream of the solenoid valve 42, and the other end of the throttling channel 431 is connected to the downstream of the solenoid valve 42, forming a parallel airflow path.

[0041] This parallel design means that even if the solenoid valve 42 is closed, the outer ring gas supply pipeline 12 will not completely stop supplying gas, because the gas can continue to flow through the throttling channel 431. In the rated load mode, the solenoid valve 42 is closed, and the gas is supplied to the outer fire ring through the throttling channel 431 at a rated flow rate, while the inner fire ring is also burning, ensuring the stability and efficiency of cooking.

[0042] When stir-frying is required, the solenoid valve 42 is opened, the ventilation volume of the outer ring air supply pipe 12 is greatly increased, the outer fire ring burns at a larger flow rate, and of course the inner fire ring is also burning. At this time, the flame is instantly enhanced, providing sufficient heat for stir-frying.

[0043] Although this design makes it impossible to completely close the outer ring air supply pipe 12, it solves the need for rapid switching between different cooking modes. The normally open state of the throttling channel 431 ensures that the outer fire ring can work stably at the rated load even in the non-stir-frying mode, and the switch of the solenoid valve 42 controls whether to enter the stir-frying mode. This flexibility greatly enriches the cooking possibilities.

[0044] More specifically, the throttling channel 431 includes a first tapered hole 4311 that gradually shrinks, a throttling hole 4312, and a second tapered hole 4313 that gradually expands in the flow direction. This design allows the gas to first accelerate in the first tapered hole when passing through the throttling channel, then be restricted in the throttling hole, and finally gradually restore the flow rate in the second tapered hole. Such a flow path can not only effectively control the gas flow rate, but also increase the gas pressure to a certain extent, ensuring that sufficient heat can be provided even in the rated load mode.

[0045] More specifically, the cross section of the throttle hole 4312 accounts for 10% to 20% of the cross section of the first channel 411. This ratio ensures that the gas can be supplied at a stable flow rate in the rated load mode, and in the stir-fry mode, the gas flow rate can be rapidly increased by opening the solenoid valve 42 to meet the high temperature requirement during stir-frying.

[0046] More specifically, the throttle 43 is detachably connected to the throttle mounting cavity 414, for example, threaded therein or plugged therein. The detachable connection design of the throttle 43 provides great convenience for the user. When cleaning or replacement is required, the user can easily remove the throttle from the throttle mounting cavity 414 without complicated tools or expertise. This design not only reduces maintenance costs, but also improves product reliability and durability.

[0047] Of course, if the throttling member 43 is removed and replaced with a sealing plug, it can become a valve body similar to the above-mentioned embodiment 1.

[0048] More specifically, the solenoid valve 42 is connected to a control circuit board, and a stir-fry control button is provided on the control circuit board. In the rated load mode, once the user presses the stir-fry control button, the control circuit board will control the solenoid valve 42 to automatically open and enter the high-fire stir-fry mode. After stir-frying for a period of time, the stir-fry mode will automatically exit, and the stir-fry mode can also be exited manually.
