Technical Field

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

[0002] With the diversification of cooking methods, users' pursuit of some ultimate cooking techniques requires a greater instantaneous heat output. A combined dual-channel rotary valve technology can achieve this increased heat output, featuring an outer ring nozzle with an independently arranged dual-nozzle structure. Typically, gas stove nozzles have an air damper adjustment device at the nozzle end, allowing users to adjust the airflow to adapt to different gas supply conditions. However, the aforementioned dual-nozzle structure cannot be directly matched with a traditional rotary air damper adjustment device, thus requiring further optimization and improvement of the damper adjustment mechanism.

Detailed Implementation

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0024] 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.

[0025] Example:

[0026] like Figure 1-2 As shown, this embodiment provides a sliding damper adjustment device, which is installed on the multi-channel gas stove stopcock valve. The multi-channel gas stove stopcock valve includes a stopcock valve body 1 and a multi-channel valve body 2, specifically installed at the multi-channel nozzle 3 of the multi-channel valve body 2.

[0027] The sliding damper adjustment device includes a furnace head end cover 4, a damper plate 5, and an elastic element. The gas outlet end of the multi-channel nozzle 3 is matched with the furnace head end cover 4 and slides with the damper plate 5. The elastic element is located between the gas outlet end of the multi-channel nozzle 3 and the damper plate 5.

[0028] The burner end cover 4 is provided with an air inlet hole, and the damper plate 5 has a baffle. During the sliding of the damper plate 5 relative to the multi-channel nozzle 3, the baffle can correspond to the position of the air inlet hole of the burner end cover 4 to adjust the size of the air inlet hole.

[0029] In this embodiment, the damper plate 5 can move relative to the burner end cover 4, thereby adjusting the relative position of the damper plate 5's partition part to the air inlet hole. This allows for adjustment of the size of the air inlet hole, i.e., the opening size of the air inlet hole, to meet different gas source requirements. It also solves the problem that the dual-nozzle structure cannot be directly matched with the traditional rotary damper adjustment device.

[0030] The specific structure of the burner end cover 4 in this embodiment is as follows:

[0031] A horizontal support 401 is provided at the air inlet of the burner end cover 4. The horizontal support 401 is provided with a first strip hole 402 that matches the air outlet of the multi-channel nozzle 3.

[0032] Specifically, the horizontal support 401 is located in the middle of the air intake hole, the air intake hole is circular in shape, and the air intake hole includes two sub-air intake holes 403 symmetrically arranged relative to the horizontal support 401.

[0033] The specific structure of the damper plate 5 in this embodiment is as follows:

[0034] It includes a horizontal plate 501, a baffle plate 502, and an adjusting handle 503. The baffle plate 502 is the baffle part of the damper plate 5. The baffle plate 502 is connected to the horizontal plate 501 and the adjusting handle 503 respectively. The horizontal plate 501 is provided with a second strip hole 504 that slides with the air outlet end of the multi-channel nozzle 3. The length of the second strip hole 504 is greater than the length of the first strip hole 402.

[0035] The baffle plate 502 is fan-shaped.

[0036] Regarding the above structure, when moving the damper plate 5 relative to the burner end cover 4, the movement of the horizontal plate 501 and the baffle plate 502 can be easily controlled by adjusting the handle 503. Specifically, when the air outlet of the multi-channel nozzle 3 is on one side of the second strip hole 504, the baffle plate 502 is on the outside of the air inlet hole; when the air outlet of the multi-channel nozzle 3 is on the other side of the second strip hole 504, the baffle plate 502 is inside the air inlet hole. This allows for adjustment of the size of the air inlet hole, i.e., the damper opening of the air inlet hole, to meet different gas source requirements.

[0037] The multi-channel gas stove stopcock valve and sliding damper adjustment device mentioned above are connected to the infrared burner and tested according to the test conditions specified in the national standard GB 16410-2020 "Household Gas Stoves"; the rated heat load is set to three heat load ranges of 4.5kW-5.0kW-5.2kW respectively.

[0038] The table below shows the measured equivalent heat load and deviation, measured heat load and CO concentration in dry flue gas (α=1, volume fraction) obtained using a flue gas analyzer.

[0039]

[0040] According to the table above, based on the parameters for selecting the damper opening, the measured equivalent heat load of each burner is within ±10% of the rated heat load; the measured CO concentration (α=1, volume fraction) in the dry flue gas of each burner is lower than the national standard requirement of ≤0.05%.

[0041] In this embodiment, the elastic element is spring 6, which is sleeved on the air outlet end of the multi-channel nozzle.

[0042] Specifically, the spring element 6 is shaped like a frustum of a cone. The multi-channel nozzle 3 is provided with a limiting platform 301. The small end of the spring element 6 is in contact with the limiting platform 301, and the large end of the spring element 6 is in contact with the damper plate 5. The spring element 6 is in a compressed state. Its structure can ensure that the damper plate 5 and the furnace head end cover 4 are relatively close to each other, ensuring the stability of their relative positions and preventing the damper plate 5 from moving and affecting the stability of the damper opening adjustment.

[0043] 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.
