[0002] Infrared gas stoves are household appliances that use infrared radiation for combustion. They mainly consist of a stove body and infrared combustion plates mounted on it. Existing infrared gas stoves suffer from uneven gas mixing and incomplete combustion, resulting in incomplete combustion of the infrared ceramic plates, uneven burning at the edges, and a long time before the ceramic plates are fully red-hot. Therefore, to avoid the shortcomings of existing technology, it is necessary to improve it. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 3 The present invention discloses an infrared gas stove, including a furnace body 1, a gas mixing layer 2 disposed in the furnace body 1, and a combustion plate 3 or a burner cap disposed at the upper end of the furnace body 1. The gas mixing layer 2 and the inner bottom surface of the furnace body 1 form a gas mixing chamber 4. The gas mixing chamber 4 is connected to the outside through the gas mixing layer 2. An air inlet 5 is provided at the bottom of the furnace body 1.

[0022] The mixing layer 2 includes a mixing plate 6, a sidewall extending upward from the outer peripheral wall of the mixing plate 6, and a flange 7 extending horizontally outward from the upper end of the sidewall. The mixing plate 6 has several air outlet holes 8. The mixing layer 2 prolongs the mixing time of the mixed gas in the mixing chamber 4, so that the injected mixed gas is swirled in the mixing chamber 4, and the mixing is more uniform.

[0023] The inner wall of the furnace body 1 is provided with a boss 9, and the flange 7 is snapped onto the boss 9, making assembly simple.

[0024] To improve mixing uniformity, the mixing layer 2 also includes a mixing mesh 10, which is positioned above the mixing plate 6. The mixing mesh 10 is made of stainless steel. The mesh aperture of the mixing mesh 10 is smaller than the aperture of the outlet holes 8 on the mixing plate 6. The space between the mixing mesh 10 and the mixing plate 6 enhances further mixing of the gas mixture. The further mixed gas exits from the mixing mesh 10 and enters the combustion plate 3 evenly, causing the combustion plate 3 to quickly turn fully red-hot. The stainless steel mesh turns red-hot rapidly upon heating, which is beneficial for infrared radiation to the combustion plate 3, thereby improving combustion efficiency.

[0025] Combustion plate 3 is an infrared ceramic plate.

[0026] The furnace body 1 has a first air inlet and a second air inlet. A first hollow pipe is installed inside the furnace body 1, and a second hollow pipe is fitted over the first hollow pipe. The first hollow pipe forms a first mixing chamber 11, which is connected to the first air inlet. The second hollow pipe and the furnace body 1 form a second mixing chamber 12, which is connected to the second air inlet. The first air inlet is located in the middle of the bottom surface of the furnace body 1, and the second air inlet is located on the side of the bottom surface of the furnace body 1 or on the side of the furnace body 1. The first mixing chamber 11 is covered with an inner flame cap 13, and the second mixing chamber 12 is covered with an annular outer flame cap or combustion plate 3. Because the first air inlet and the inner flame cap 13 are directly connected, and the inner flame cap 13 is a direct-injection flame cap, the flame exiting the inner flame cap 13 is a direct-injection flame, which not only improves combustion efficiency but also reduces the noise of the direct-injection flame.

[0027] The outer flame cover has a long strip-shaped flame outlet 14 opening from the inside out. The long strip-shaped flame outlet 14 is inclined in a clockwise direction, and the flame direction is also inclined along the opening direction of the long strip-shaped flame outlet 14 during combustion.

[0028] In the first embodiment, an air inlet 5 is provided at the bottom of the furnace body 1, and the mixing layer 2 and the infrared ceramic sheet are stacked sequentially on the boss 9. A decorative ring 15 is also provided at the top of the furnace body 1, and an internal ignition needle 16 is provided inside the furnace body 1. The gas in the mixing chamber 4 rises through the mixing layer 2 to improve combustion efficiency, making the infrared ceramic sheet quickly turn fully red.

[0029] In the second embodiment, the furnace body 1 has a first air inlet and a second air inlet. The furnace body 1 contains a corresponding annular mixing layer 17 and an annular mixing mesh 18. The inner burner cap 13 in the center provides an open flame, and the periphery consists of annular combustion plates 19. Compared to a gas stove that only uses combustion plates 3, the inner burner cap 13 provides an open flame more efficiently.

[0030] As a third implementation test, the furnace body 1 has a first air inlet and a second air inlet. The inner flame cover 13 in the middle and the outer annular flame cover 20 around the perimeter can both provide open flame, realizing open flame cooking, which can achieve more complete combustion and solve the problems of low firepower and slow heating of outdoor stoves. In order to reduce costs, the mixing layer 2 can be omitted in the furnace body 1.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
