[0037] In addition, in this application, descriptions such as "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0038] This application provides a gas stove, which combines Figure 1 , Figure 2 and Figure 3 As shown, the gas stove includes a burner 1000 and a heat collecting disc 2000. The heat collecting disc 2000 surrounds the burner 1000. The heat collecting disc 2000 and the burner 1000 enclose a combustion chamber 3100, and a first air flow channel 3200 is provided between the heat collecting disc 2000 and the burner 1000. The first air flow channel 3200 communicates the combustion chamber 3100 with the outside space.

[0039] By providing the first air flow channel 3200 between the heat collecting disc 2000 and the burner 1000, and the first air flow channel 3200 communicating the combustion chamber 3100 with the outside space, secondary air can enter the combustion chamber 3100 from the outside space along the first air flow channel 3200, optimizing the supplement of secondary air, avoiding the obstruction of the flow of secondary air caused by the heat collecting disc 2000, making the combustion of the gas ejected by the burner 1000 more complete, and being beneficial to improving the combustion efficiency of the gas stove.

[0040] Specifically, the burner 1000 is a component for realizing gas combustion. The gas stove includes a valve body. After the valve body is opened, the gas filled with liquefied gas or pipeline natural gas is transmitted along the pipeline, and the gas passes through the valve body and is sprayed out through the nozzle. The gas sprayed from the nozzle is sprayed into the interior of the burner 1000. In the process of gas spraying into the interior of the burner 1000, air is simultaneously introduced. For the introduction of air, please refer to the relevant technology. It is generally based on the Venturi principle. In the process of gas spraying into the interior of the burner 1000, a negative pressure is formed on the surrounding environment, so that the air of the surrounding environment is synchronously introduced into the interior of the burner 1000 with the injection of gas (this part of the air entering the interior of the burner 1000 through the introduction effect is called introduction air, and the introduction air is primary air). The introduction air and the gas are mixed in the interior of the burner 1000 and then sprayed out from the interior of the burner 1000, and then ignited to form a flame. In the process of gas combustion, through buoyancy and suction, the surrounding environment will supplement air to the flame (this air is called secondary air), thereby assisting the combustion of the gas.

[0041] The burner 1000 will emit heat to the surrounding environment during the combustion process. In order to avoid the excessive loss of heat, an energy collecting plate 2000 is provided. The energy collecting plate 2000 surrounds the burner 1000, thereby forming a combustion chamber 3100 with the burner 1000. For example, the burner 1000 includes a burner head 1100 and a fire cover (the fire cover includes an outer ring fire cover 1200 and an inner ring fire cover 1300) provided on the burner head 1100. When the energy collecting plate 2000 surrounds the burner 1000, the space surrounded by the energy collecting plate 2000 and the space above the fire cover constitute the combustion chamber 3100. The gas is sprayed into the combustion chamber 3100 through the fire cover and ignited to form a flame. The cookware is provided above the energy collecting plate 2000 and the burner 1000 (i.e., above the combustion chamber 3100), thereby achieving heating of the cookware. It is understandable that, since the energy focusing disk 2000 surrounds the burner 1000 , it is easy to hinder the burner 1000 from sucking in secondary air from the surrounding environment.

[0042] To this end, a first air flow channel 3200 is provided between the energy-gathering disk 2000 and the burner 1000. That is, when the energy-gathering disk 2000 surrounds the burner 1000, it is not in complete contact with the burner 1000, but there is a certain space between the two, and this space constitutes the first air flow channel 3200. For example, the first air flow channel 3200 is provided between the inner side of the bottom of the energy-gathering disk 2000 and the burner 1000. The formation of the first air flow channel 3200 lays the foundation for the flow of secondary air. When the burner 1000 is working, the secondary air in the surrounding environment enters the combustion chamber 3100 through the first air flow channel 3200, so as to be supplemented to the flame, improve the supply of secondary air, avoid affecting the flow of secondary air due to the setting of the energy-gathering disk 2000, be beneficial to the combustion of gas, and improve the combustion efficiency of the gas stove.

[0043] Combined with Figure 4 and Figure 5 As shown, in some embodiments, along the direction of air flow, the through-flow cross-section of the first air flow channel 3200 gradually becomes smaller. The so-called through-flow cross-section is the cross-section perpendicular to the fluid flow direction. By designing the through-flow cross-section of the first air flow channel 3200 to gradually become smaller along the air flow direction, the secondary air can be accelerated when flowing through the first air flow channel 3200, so that the secondary air can enter the combustion chamber 3100 more quickly and be supplemented to the flame, improving the efficiency of oxygen supply and being more beneficial to the combustion of gas.

[0044] Continuing to combine Figure 4 and Figure 5 As shown, in some embodiments, the burner 1000 includes a burner head 1100 and an outer ring fire cap 1200. The outer ring fire cap 1200 is arranged on the burner head 1100, and the aforementioned first air flow channel 3200 is provided between the energy-gathering disk 2000 and the outer ring fire cap 1200. Specifically, the outer ring fire cap 1200 constitutes at least a part of the fire cap mentioned above. For example, the fire cap includes an inner ring fire cap 1300 and an outer ring fire cap 1200. Both the inner ring fire cap 1300 and the outer ring fire cap 1200 are arranged on the burner head 1100, and the outer ring fire cap 1200 surrounds the inner ring fire cap 1300. The outer ring fire cap 1200 is on the outside and can directly cooperate with the energy-gathering disk 2000 to form the first air flow channel 3200, simplifying the structure. It can be understood that the outer ring fire cap 1200 is provided with a fire outlet 1211. Since the first air flow channel 3200 is formed between the outer ring fire cap 1200 and the energy-gathering disk 2000, the secondary air is closer to the fire outlet 1211 after entering the combustion chamber 3100, which is more beneficial to mixing with the gas ejected from the fire outlet 1211 and assisting the combustion of the gas.

[0045] Continuing to combine Figure 4 and Figure 5As shown, in some embodiments, the first air flow channel 3200 extends upward from bottom to top. It can be understood that the upward extension from bottom to top can be a vertical upward extension or an inclined upward extension. After the secondary air enters the first air flow channel 3200, it flows upward and enters the combustion chamber 3100. The flue gas in the combustion chamber 3100 floats upward due to the high temperature. By arranging the first air flow channel 3200 to extend upward from bottom to top, it is possible to minimize the obstruction of the flue gas entering the first air flow channel 3200 to the passage of the secondary air through the first air flow channel 3200 into the combustion chamber 3100, and further improve the supply efficiency of the secondary air.

[0046] Combined with Figure 5 As shown, in some embodiments, the outer ring burner cap 1200 includes an inner wall 1210 and an outer wall 1220. A corner portion 1230 is provided between the inner wall 1210 and the outer wall 1220. The inner wall 1210 is provided with a flame outlet 1211, and a first air flow channel 3200 is provided between the outer wall 1220 and the energy concentrating disc 2000.

[0047] Specifically, the outer ring burner cap 1200 can be circular or non-circular (such as square-shaped). The inner side of the outer ring burner cap 1200 (the side facing the center of the burner 1000) is regarded as the inner wall 1210, and the outer side of the outer ring burner cap 1200 (the side facing away from the center of the burner 1000) is regarded as the outer wall 1220. When the energy concentrating disc 2000 surrounds the burner 1000, a first air flow channel 3200 is provided between the energy concentrating disc 2000 and the outer wall 1220 of the outer ring burner cap 1200. And by providing a corner portion 1230 between the outer wall 1220 and the inner wall 1210, when the secondary air is transmitted along the first air flow channel 3200 and flows through the corner portion 1230, it is equivalent to a sudden change in the flow channel wall of the first air flow channel 3200, and part of the secondary air changes direction along the corner portion 1230. And since the inner wall 1210 of the outer ring burner cap 1200 is provided with the flame outlet 1211, in this way, part of the secondary air can flow toward the flame outlet 1211, which is beneficial to supplement the secondary air to the root of the flame, thereby further improving the combustion efficiency of the gas.

[0048] Combined with Figure 5 As shown, in some embodiments, the outer wall 1220 is designed to be tapered from bottom to top. It can be understood that the orientation in this article is referenced with the gas stove in the installation environment. The side of the gas stove close to the ground is the bottom, and the side of the gas stove away from the ground is the top. In this article, by designing the outer wall 1220 to be tapered from bottom to top, it is beneficial for the secondary air to flow toward the center of the combustion chamber 3100, making the secondary air more efficiently assist in the combustion of the gas.

[0049] Combined with Figure 5As shown, in some embodiments, the inner wall 1210 of the outer ring burner cap 1200 is designed to be gradually expanding from bottom to top. It can be understood that the space surrounded by the inner wall 1210 of the outer ring burner cap 1200 forms a part of the combustion chamber 3100. By designing the inner wall 1210 of the outer ring burner cap 1200 to be gradually expanding from bottom to top, it is beneficial for heat to radiate upward and improve the heating effect on the cookware. In particular, when the outer wall 1220 of the outer ring burner cap 1200 is gradually shrinking in the direction from bottom to top, the outer wall 1220 of the outer ring burner cap 1200 and the inner wall 1210 of the outer ring burner cap 1200 are substantially intersecting to form a corner portion 1230. When the secondary air flows along the first air flow channel 3200 and passes through the corner portion 1230, part of the secondary air can change direction and flow along the inner wall 1210 of the outer ring burner cap 1200, and these secondary airs are directly supplemented to the root of the flame.

[0050] Furthermore, a part of the energy - concentrating disc 2000 can be designed in the gradually expanding direction of the inner wall 1210. For example, referring to Figure 5 as shown, an extension line is made in the gradually expanding direction of the inner wall 1210 ( Figure 5 the dotted line in the figure), and the side of the energy - concentrating disc 2000 that forms the first air flow channel 3200 with the outer ring burner cap 1200 intersects with the extension line. In this way, when the secondary air flows along the first air flow channel 3200 and passes through the corner portion 1230, more secondary air changes direction and flows towards the flame outlet 1211, which is beneficial to further improving the combustion effect of the gas.

[0051] Combined with Figure 4 、 Figure 5 、 Figure 7 and Figure 8 as shown, in some embodiments, the burner head 1100 is provided with a second air flow channel 3300. The second air flow channel 3300 is arranged below the outer ring burner cap 1200, and the second air flow channel 3300 communicates the external space with the combustion chamber 3100.

[0052] Specifically, a first air flow channel 3200 is formed between the outer ring burner cap 1200 and the outer wall 1220, and the inner wall 1210 is provided with a flame outlet 1211. Therefore, the secondary air passing through the first air flow channel 3200 enters the combustion chamber 3100 from above the flame outlet 1211. Since the outer ring burner cap 1200 is covered on the burner head 1100, the burner head 1100 is located below the outer ring burner cap 1200, and the burner head 1100 is provided with a second air flow channel 3300. Thus, the second air flow channel 3300 is located below the outer ring burner cap 1200, and the secondary air passing through the second air flow channel 3300 is supplemented to the combustion chamber 3100 from below the flame outlet 1211. In this way, the secondary air is supplemented from the upper and lower sides of the flame outlet 1211, greatly optimizing the effect of secondary air supplementation and further improving the combustion effect of the gas. For example, the second air flow channel 3300 is in communication with the space between the outer ring burner cap 1200 and the inner ring burner cap 1300, and the space between the outer ring burner cap 1200 and the inner ring burner cap 1300 is located below the combustion chamber 3100 and is in communication with the combustion chamber 3100.

[0053] Combined with Figure 1 、 Figure 3 and Figure 6 As shown, the energy - gathering disc 2000 is provided with supporting feet 2500. The supporting feet 2500 are used to support on a supporting surface to lift the energy - gathering disc 2000, so that the first air flow channel 3200 communicates with the outside space through the lower part of the energy - gathering disc 2000.

[0054] Specifically, the supporting feet 2500 are used to support the energy - gathering disc 2000. For example, the supporting feet 2500 are arranged on the lower surface of the energy - gathering disc 2000 and support on the panel of the gas stove or the liquid - receiving tray of the gas stove. Both the panel of the gas stove and the liquid - receiving tray of the gas stove can be regarded as the supporting surface. By such an arrangement, the energy - gathering disc 2000 is lifted relative to the supporting surface, and a certain space is formed between the energy - gathering disc 2000 and the supporting surface. This air is used for the first air flow channel 3200 to communicate with the outside space. The secondary air in the outside space enters the first air flow channel 3200 through the lower part of the energy - gathering disc 2000 and then enters the combustion chamber 3100. It can be understood that the second air flow channel 3300 can also utilize the space between the energy - gathering disc 2000 and the supporting surface to communicate with the outside space. In addition, by such an arrangement, the energy - gathering disc 2000 can also shield the first air flow channel 3200 and the second air flow channel 3300 to avoid exposure.

[0055] Combined with Figure 5 As shown, in some embodiments, the energy - gathering disc 2000 includes a first disc body 2100 and a second disc body 2200, and a cavity 2300 is arranged between the first disc body 2100 and the second disc body 2200.

[0056] Specifically, the first disk body 2100 and the second disk body 2200 can be separate components and are connected and fixed together by connecting means, or the first disk body 2100 and the second disk body 2200 are an integral structure formed by stamping and bending. A cavity 2300 is formed between the first disk body 2100 and the second disk body 2200. For example, the first disk body 2100 surrounds the burner 1000, the second disk body 2200 surrounds the burner 1000, and the first disk body 2100 is disposed above the second disk body 2200. Through the setting of the cavity 2300, the cavity 2300 plays a certain heat insulation role, enhancing the heat preservation performance of the energy-gathering disk 2000, so that heat is not easily transferred to the external space through the energy-gathering disk 2000.

[0057] Furthermore, as shown in Figure 5 a gap 2400 is provided between the inner sides of the first disk body 2100 and the second disk body 2200. The gap 2400 communicates with the cavity 2300 and the first air flow channel 3200. Through the setting of the gap 2400, when the energy-gathering disk 2000 is heated, the gas in the cavity 2300 is discharged through the gap 2400, avoiding abnormal noise caused by too high air pressure. It can be understood that when the energy-gathering disk 2000 is heated, the gas in the cavity 2300 also gets hot. Since the gap 2400 communicates with the first air flow channel 3200, when the secondary air enters the combustion chamber 3100 along the first air flow channel 3200, the heat in the cavity 2300 is transferred to the secondary air through the gap 2400, realizing the preheating of the secondary air and avoiding too large a temperature difference after the secondary air enters the combustion chamber 3100, which is beneficial to improving the combustion efficiency.

[0058] As shown in Figure 5 in some embodiments, the inner side of the first disk body 2100 is bent downward to cover the inner wall 1210 of the second disk body 2200. For example, the first disk body 2100 is disposed above the second disk body 2200. By bending the inner side of the first disk body 2100 downward, the inner side of the first disk body 2100 shields the inner side of the second disk body 2200, avoiding the exposure of the gap 2400 between the first disk body 2100 and the second disk body 2200, and at the same time preventing residues from entering the cavity 2300 through the gap 2400.

[0059] The second aspect of the present application discloses an integrated appliance. The integrated appliance includes the gas stove of the above embodiment. The gas stove includes a burner 1000 and an energy-gathering disk 2000. The energy-gathering disk 2000 surrounds the burner 1000. The energy-gathering disk 2000 and the burner 1000 enclose a combustion chamber 3100, and a first air flow channel 3200 is provided between the energy-gathering disk 2000 and the burner 1000. The first air flow channel 3200 communicates the combustion chamber 3100 with the external space.

[0060] A first air flow channel 3200 is provided between the energy-gathering disc 2000 and the burner 1000. That is, when the energy-gathering disc 2000 surrounds the burner 1000, it is not in complete contact with the burner 1000, but there is a certain space between the two. This space constitutes the first air flow channel 3200. The formation of the first air flow channel 3200 lays the foundation for the flow of secondary air. When the burner 1000 is working, the secondary air in the surrounding environment enters the combustion chamber 3100 through the first air flow channel 3200, so as to supplement to the flame, improve the supply of secondary air, avoid affecting the flow of secondary air due to the setting of the energy-gathering disc 2000, is beneficial to the combustion of gas, and improves the combustion efficiency of the gas stove.

[0061] The so-called integrated appliance is a device that integrates the functions of an integrated gas stove and another traditional appliance. For example, at least one of a microwave oven, an oven, a steamer, and a range hood can be integrated with the gas stove to form an integrated appliance. Of course, the integrated appliance is not limited to the appliances listed above. As long as it can achieve more functions when integrated with the gas stove compared to a single gas stove, it can be regarded as an integrated appliance. It can be understood that the gas stove of the integrated appliance in this embodiment adopts the technical solution of the above embodiment, so it has at least the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.

[0062] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structural transformation made under the concept of the present application by using the content of the specification and drawings of the present application, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present application.
