Description

Technical Field

[0001] This utility model belongs to the technical field of household gas stove equipment, specifically relating to a combined multi-channel gas stove stopcock valve. Background Technology

[0002] The national standard GB 16410-2020 "Household Gas Stoves" stipulates that the rated heat load of a single burner of a gas stove should be ≤5.23kW. At the same time, the heat load of the stove should meet the following conditions: gas stoves with two or more burners, gas-electric stoves and integrated stoves should have one main burner, and their measured equivalent heat load should be: ≥3.5kW for ordinary stoves and ≥3.0kW for infrared stoves.

[0003] Currently, the mainstream cooktops on the market have a heat load of 4.0-5.0kW for ordinary cooktops and 3.0-4.0kW for infrared cooktops. Obviously, although the rated heat load of infrared cooktops seems to be lower than that of ordinary cooktops, due to the superior technology of infrared cooktops, they have the characteristics of high efficiency and energy saving, uniform heating, and high combustion surface temperature. To a certain extent, the mainstream heat load of infrared cooktops is basically equivalent to that of ordinary cooktops, and thus can basically meet most routine cooking needs.

[0004] With the diversification of cooking methods, users' pursuit of some extreme cooking methods requires a greater instantaneous heat to meet specific needs. In particular, when users stir-fry, the temperature inside the pan drops rapidly the moment the ingredients are put into the pan, affecting the taste of the dish and the speed of serving.

[0005] To meet the demand for extreme stir-frying, existing infrared household gas stoves have significant room for optimization, innovation, and improvement. Utility Model Content

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0047] Example:

[0048] Example 1:

[0049] Reference Figures 1 to 3 As shown, this embodiment provides a combined multi-channel gas stove stopcock valve, including a stopcock valve body 1 and a multi-channel valve body 2. The stopcock valve body 1 is connected to the multi-channel valve body 2, and the multi-channel valve body 2 includes several independently arranged channels. In this embodiment, the structural dimensions of two independently arranged channels are the same, and two independently arranged channels form a channel group 25. See details below. Figure 1 The number of channels in this group 25 is one;

[0050] In this embodiment, the number of channel groups can also be two or more. The plug valve body 1 is provided with an outer ring channel 12 connected to the multi-channel valve body 2, wherein the central axis of the channel group 25 overlaps with the central axis of the outer ring channel 12. See [reference needed]. Figure 3 There are multiple channels 25, and the channels of the channel group 25 are arranged in a circle around the central axis of the outer ring channel 12 of the plug valve body 1.

[0051] Example 2:

[0052] Reference Figures 4 to 6 As shown, this embodiment provides a combined multi-channel gas stove stopcock valve, including a stopcock valve body 1, a multi-channel valve body 2, a small flame nozzle 3, a main flame nozzle 4, and an auxiliary nozzle 5.

[0053] The plug valve body 1 includes an inner ring channel 11, an outer ring channel 12, and a mounting flange 13. The mounting flange 13 is disposed on the outer ring channel 12, and the multi-channel valve body 2 is mounted on the outer ring channel 12 of the plug valve body 1 via a flange connection.

[0054] The valve chamber of the multi-channel valve body 2 includes a main channel 21, a secondary channel 22 and a connecting channel 23. The main channel 21 and the secondary channel 22 are connected and communicate with each other through the connecting channel 23. At this time, the main channel 21 and the secondary channel 22 are in communication with the plug valve body 1. The main channel 21 and the secondary channel 22 are connected to the corresponding main flame nozzle 4 and auxiliary nozzle 5 through threaded connection. The small flame nozzle 3 is connected to the inner ring channel 11 of the plug valve body 1 through a threaded connection structure.

[0055] Specifically, in this embodiment, the main channel 21 is relatively longer than the secondary channel 22. This is to stagger the air ejection zones of the aforementioned nozzles and obtain a better ejection effect. In other embodiments, the length relationship between the two can be flexibly designed according to requirements.

[0056] Specifically, in this embodiment, the multi-channel valve body 2 is designed to be installed on the outer ring channel 12 of the plug valve body 1. In other embodiments, the multi-channel valve body 2 is designed to be installed on the inner ring channel 11. Furthermore, there are two multi-channel valve bodies 2, which are respectively installed on the inner ring channel 11 and the outer ring channel 12. In this case, the structure of the small flame nozzle 3 can be eliminated.

[0057] Specifically, in this embodiment, the main channel 21 of the multi-channel valve body 2 and the outer ring channel 12 of the plug valve body 1 are coaxially arranged. In other embodiments, the main channel 21 and the outer ring channel 12 of the plug valve body 1 may also be non-coaxially arranged.

[0058] Specifically, in this embodiment, the main channel 21 and the secondary channel 22 of the multi-channel valve body 2 are arranged parallel to the outer ring channel 12. The relative distance between the main channel 21 and the secondary channel 22 is determined based on the burner ejector tube structure. The structural mold of this application is relatively simple and the cost is relatively economical. In other embodiments, for better premixing effect, the main channel 21 and the outer ring channel 12 are arranged parallel to each other, and the secondary channel 22 is designed with an angle to the main channel 21, that is, it is inclined. The value of the angle can be determined according to the burner structure. Furthermore, the main channel 21, the secondary channel 22, and the outer ring channel 12 can all be designed with an angle.

[0059] Specifically, in this embodiment, the multi-channel valve body 2 has only one secondary channel 22. In other embodiments, multiple secondary channels 22 are designed, and the number of auxiliary nozzles 5 corresponds to the number of secondary channels 22.

[0060] The combination of the main channel 21 and the secondary channel 22 in this embodiment can significantly increase the primary air ejection capacity of the valve body. By increasing the secondary channel 22, the heat load of the gas stove can be increased, while a better premixing effect can be achieved, thereby improving the flue gas problem.

[0061] Example 3:

[0062] Reference Figures 7 to 9 As shown, the difference between this embodiment and Embodiment 2 is that a solenoid valve 24 is used to switch the secondary channel and the main body of the plug valve to a connected state or a closed state.

[0063] Specifically, the multi-channel valve body 2 includes a main channel 21, a secondary channel 22 and a connecting channel 23. The main channel 21 and the secondary channel 22 are connected together through the connecting channel 23. The sealing face 231 is provided at the communication between the connecting channel 23 and the secondary channel 22. The solenoid valve 24 is provided at the connecting channel. The solenoid valve 24 has a diaphragm that can move within the connecting channel 23.

[0064] When the diaphragm comes into contact with the sealing surface 231, the secondary channel 22 is closed to the main body 1 of the stop valve. When the diaphragm separates from the sealing surface 231, the secondary channel 22 is connected to the main body 1 of the stop valve. At the same time, during the above-mentioned movement process, the main channel 21 is always connected to the main body 1 of the stop valve.

[0065] Therefore, when the secondary channel 22 (when the diaphragm is in contact with the sealing surface 231) is closed, the main body of the stopcock valve is in a low heat load state, and when the secondary channel 22 is open (when the diaphragm is separated from the sealing surface 231), the main body of the stopcock valve is in a high heat load state. This design allows the stove to have a high heat load burst, while effectively ensuring that the stove is not always in a high heat load state, thus ensuring the service life of the stove.

[0066] In summary, the advantages of this application are as follows:

[0067] 1. The valve chamber design of the multi-channel valve body can greatly improve the primary air injection and mixing capacity of the gas, achieving a greater heat load with the same burner volume, and meeting the user's demand for extreme stir-fry cooking.

[0068] 2. The secondary channels of the multi-channel valve body can also be designed to be connected or closed as needed, so as to realize the design of normal high heat load or instantaneous increase in heat load, thereby meeting the firepower needs of different users.

[0069] 3. The overall structure is simple, the functionality is expandable, it can adapt to existing burner structures, and it has strong versatility.

[0070] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
