Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0026] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0027] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0028] This application is described below with reference to the accompanying drawings and specific embodiments: The working principle of a gas stove is as follows: High-pressure gas (natural gas or liquefied petroleum gas) enters the valve body of the gas stove from the gas pipeline. After the valve body opens, it flows into the nozzle. Since the nozzle size is very small, generally less than 2mm, the high-pressure gas becomes high-speed low-pressure gas after flowing out of the nozzle. It enters the Venturi structure of the burner head to form a negative pressure (lower than atmospheric pressure). Therefore, primary air is injected into the burner head. After the primary air mixes with the gas, it flows out of the burner head and enters the gas distribution plate and burner cap for combustion. During the combustion process, the air in the environment will be replenished a second time, namely secondary air, to ensure complete combustion of the gas.

[0029] As can be seen from the working principle, the primary and secondary air volumes are the core key factors ensuring complete combustion of gas. For existing gas stove combustion systems, the gas mixes with primary air before combustion, so the primary air is considered to participate almost entirely in the reaction. Secondary air participates in the reaction during combustion due to buoyancy and the entrainment effect of the high-speed gas jet; therefore, not all of the secondary air participates completely. To ensure complete combustion, the total air volume should be minimized as much as possible to reduce the heat released from combustion that heats excess air, thereby improving thermal efficiency.

[0030] Currently, most manufacturers improve the primary air coefficient by optimizing the burner head, gas distribution plate, and burner cap structure. However, several core issues remain unresolved: the primary air coefficient decreases as flow resistance increases, and the main sources of flow resistance are the burner hole structure and area. Thicker burner holes, smaller total area, and smaller burner hole diameter all increase flow resistance. However, thicker burner holes and smaller burner hole diameters are beneficial for combustion stability, while smaller total area is beneficial for improving heat exchange efficiency. Therefore, a contradiction exists. Consequently, in some applications, it is necessary to increase flow resistance, resulting in a lower primary air coefficient and preventing the achievement of optimal combustion.

[0031] In other words, the above-mentioned method of increasing the amount of primary air supply is still insufficient to ensure complete combustion of the gas under optimal conditions, and there is room for improvement.

[0032] Based on the above-mentioned technical problems, this application provides a stove shell and a gas stove, which aims to improve the amount of primary air supply to at least a certain extent, so as to make the gas burn completely under the best conditions.

[0033] Figure 1 This is a schematic diagram of the structure of a gas stove according to an embodiment of this application, combined with... Figure 1 The gas stove includes a cooktop shell 100 and a burner 200 mounted on the cooktop shell 100.

[0034] Figure 2 for Figure 1 A top view of the stove shell after removing the panel. (Combined with...) Figure 1 as well as Figure 2 The stove shell 100 of this application embodiment includes a cover 101 and a fan 102. The burner 200 is mounted on the cover 101, and the fan 102 is disposed inside the cover 101. The fan 102 is used to increase the internal air pressure of the cover 101. A pressure relief port 103 is also provided on the cover wall of the cover 101. An air inlet for installing the burner 200 is provided between the fan 102 and the pressure relief port 103. The direction from the fan 102 to the pressure relief port 103 is the air intake direction of the primary air of the burner 200.

[0035] The gas stove provided in this application includes a stove shell 100 and a burner 200 mounted on the stove shell 100. A fan 102 is provided inside the cover 101 of the stove shell 100 to increase the internal air pressure of the cover 101. When the fan 102 is turned on, air can be continuously input into the cover 101 through the fan 102, thereby increasing the internal air pressure of the cover 101. Since a pressure relief port 103 is provided on the cover wall of the cover 101, air can flow from the fan 102 to the pressure relief port 103.

[0036] Since the air inlet of the burner 200 in this embodiment is located between the fan 102 and the pressure relief port 103, the primary air intake direction of the burner 200 is the direction from the fan 102 to the pressure relief port 103. In this way, when the gas stove is in use, the fan 102 is started. When the air flows from the fan 102 to the pressure relief port 103, the flowing air can enter the burner through the air inlet, thereby increasing the amount of primary air replenishment. This can, to a certain extent, allow the gas to burn completely under optimal conditions and improve the combustion efficiency of the gas.

[0037] The cover 101 of this application embodiment is box-shaped, including a panel and a box with an open top. The box is embedded in the stove, and the panel is fitted into the open part of the box to seal the box. The panel is provided with a through hole for the burner to pass through, so as to facilitate the installation of the burner. This is the prior art, and this application embodiment will not be described in detail here.

[0038] Combination Figure 1 as well as Figure 2 In this embodiment of the application, the cover 101 of the stove shell 100 is provided with two parts for assembling the burner 200. The two parts for assembling the burner 200 can be arranged opposite each other along the center line of the width direction of the cover 101. The fan 102 is arranged between the two parts for assembling the burner 200, so that the primary air flow of the two burners 200 can be increased by one fan 102.

[0039] Combination Figure 2 In this embodiment of the application, the fan 102 is disposed on any side wall of the cover 101 along its length, preferably on the side wall of the cover 101 away from the user in the use state.

[0040] Specifically, in combination Figure 2 In this embodiment of the application, an air inlet is provided in the middle of the rear side wall of the cover 101 along its length. The fan 102 is mounted on the air inlet by means of a bracket. The output end of the fan 102 can face the front side wall of the cover 101 to realize the assembly of the fan 102 on the cover 101.

[0041] Figure 3 for Figure 2 The diagram shown is a structural schematic of the enclosure without a fan installed. (Combined with...) Figure 2 as well as Figure 3 In this embodiment of the application, a support plate 104 may be provided at the bottom of the cover 101, and the bottom of the fan 102 is supported by the support plate 104 to improve the stability of the fan 102 assembled inside the cover 101.

[0042] It should be noted that the front and rear sides in this application embodiment refer to the orientation of the gas stove when it is in use. The rear side wall of the cover 101 along its length is the side wall away from the user, and the front side wall of the cover 101 along its length is the side wall closer to the user.

[0043] Of course, the fan 102 in this embodiment can also be installed in other locations, such as mounting the fan 102 on the bottom of the cover 101 between the two burners 200, etc., and this embodiment does not limit this. In this case, two fans 102 can also be provided, each fan 102 can be directed toward the corresponding burner 200, that is, the air intake of the corresponding burner 200 can be controlled by one fan 102.

[0044] Combination Figure 2 Since the gas stove in this embodiment is equipped with two burners, the cover 101 of this embodiment is provided with two pressure relief ports 103 corresponding to the burners 200. These pressure relief ports 103 are preferably located at the bottom of the cover 101, and each pressure relief port 103 is positioned between the projections of the burner head 201 and the gas distribution plate 202 of the corresponding burner 200 at the bottom of the cover 101. When the gas stove is in use, the control fan 102 is activated. As air flows from the fan 102 towards the pressure relief port 103, the flowing air can enter the burner through the air inlet, thereby increasing the amount of primary air supplied. This, in turn, allows the gas to burn completely under optimal conditions, improving the combustion efficiency of the gas.

[0045] The pressure relief port 103 in this embodiment can be an opening with a large size. Of course, it can also be composed of multiple small holes. That is, the size of the opening of the pressure relief port 103 can be specifically set according to the actual situation. This embodiment does not make specific limitations here.

The flame holes on the inner ring burner cap 203 are connected to the inner ring injection channel of the burner head 201 through the gas distribution plate 202. Air and fuel can be injected into the flame holes of the inner ring burner cap 203 through the inner ring injection channel of the burner head 201. The flame holes on the outer ring burner cap 204 are connected to the outer ring injection channel of the burner head 201 through the gas distribution plate 202. Air and fuel can be injected into the flame holes of the outer ring burner cap 204 through the outer ring injection channel of the burner head 201. This is prior art, and this embodiment will not elaborate on it.

[0047] It should be noted that, in the embodiments of this application, the inlets of the inner ring ejector channel and the outer ring ejector channel of the burner head 201 are the air inlets of the aforementioned burner.

[0048] In order to adjust the primary air flow rate of the inner and outer ring ejector channels of the burner head 201, the burners in this application embodiment all include damper plates for controlling the opening degree of the inlets of the inner and outer ring ejector channels. By rotating the damper plates, the opening degree of the primary air inlets of the inner and outer ring ejector channels can be adjusted, thereby adjusting the primary air flow rate of the inner and outer ring ejector channels.
