[0002] Nowadays, more and more people like outdoor camping activities, and many people hope to produce hot water for washing hands and taking a bath when the weather is cold. In outdoor environments, there is often wind. When the wind speed is high, it will cause the outside air to enter the water heater from the exhaust port, so that the smoke inside the water heater will flow back, inhibiting the exhaust of the smoke from the exhaust port, and the fuel in the water heater will not burn completely, which will also produce more harmful substances. Utility Model Content
[0003] In order to overcome the above technical defects, the utility model discloses an outdoor gas water heater, which aims to solve the problem that smoke exhaust is inhibited when the outdoor wind speed is high.
[0004] The utility model provides an outdoor gas water heater, comprising:
[0005] A chassis, the chassis having a receiving cavity, and an air inlet is arranged at the bottom side of the receiving cavity;
[0006] A burner, the burner is arranged in the accommodating cavity, and the bottom of the burner has an opening;
[0007] a heat exchanger, the heat exchanger being arranged above the burner and communicating with the burner;
[0008] A smoke collecting hood, wherein the smoke collecting hood has a smoke collecting cavity, the smoke collecting cavity is located above the burner and is connected to the burner, and exhaust ports connected to the outside are arranged on opposite sides of the smoke collecting cavity;
[0009] Two wind shields are rotatably installed in the smoke collecting chamber and are respectively arranged close to the two exhaust ports; wherein the wind shield has an exhaust position and a wind shield position relative to the exhaust port, and when the wind shield is located at the exhaust position, the wind shield is tilted, and there is a space above and / or below the wind shield for smoke to flow through; when the wind shield rotates from the exhaust position to the wind shield position, the height of the wind shield increases continuously.

The height of the wind shield becomes larger, thereby increasing the blocking area of the wind shield to the outside air, blocking most of the outside air from passing through the wind shield and entering directly above the heat exchanger. At the same time, the smoke in the smoke collecting chamber flows out through the exhaust port on the other side. Therefore, the utility model can ensure that the smoke can flow out when it is windy by setting two exhaust ports and two rotatable wind shields, thereby avoiding smoke accumulation, allowing the fuel to be fully burned, and reducing the generation of harmful substances.
[0011] In a preferred embodiment, a protruding first limit column and a second limit column are provided on the wall surface of the smoke hood, and when the wind shield is located at the exhaust position, the wind shield abuts against the first limit column; when the wind shield is located at the wind shielding position, the wind shield abuts against the second limit column.

[0032] A smoke collecting hood 4, wherein the smoke collecting hood 4 has a smoke collecting cavity 41, the smoke collecting cavity 41 is located above the burner 2 and is in communication with the burner 2, and exhaust ports 42 in communication with the outside are arranged on opposite sides of the smoke collecting cavity 41;
[0033] Two wind shields 5 are rotatably installed in the smoke collecting chamber 41 and are respectively arranged close to the two exhaust ports 42; wherein, the wind shield 5 has an exhaust position and a wind shielding position relative to the exhaust ports 42, and when the wind shield 5 is located at the exhaust position, the wind shield 5 is tilted, and there is a space above and / or below the wind shield 5 for smoke to flow through; when the wind shield 5 rotates from the exhaust position to the wind shielding position, the height of the wind shield 5 continues to increase.
[0034] Compared with the prior art, the utility model provides an outdoor gas water heater. When the outdoor environment is good, the smoke can be discharged through two exhaust ports 42, which speeds up the exhaust speed of the smoke, thereby speeding up the air circulation and effectively improving the combustion efficiency of the fuel; when the outdoor wind speed is high, the outside air is blown into the smoke hood 4 through the exhaust port 42 on one side, and the blown air flow drives the wind shield 5 to rotate. The height of the wind shield 5 becomes larger, thereby increasing the blocking area of the wind shield 5 to the outside air, blocking most of the outside air outside, so that most of the outside air cannot pass through the wind shield 5 to enter directly above the heat exchanger 3. At the same time, the smoke in the smoke collecting chamber 41 flows out through the exhaust port 42 on the other side. Therefore, the utility model can ensure that the smoke can flow out when it is windy by setting two exhaust ports 42 and two rotatable wind shields 5, thereby avoiding smoke accumulation, allowing the fuel to be fully burned, and reducing the generation of harmful substances.

[0036] Furthermore, in another embodiment, in order to limit the rotation range of the wind shield 5, a protruding first limit column and a second limit column are provided on the wall surface of the smoke hood 4. When the wind shield 5 is located at the exhaust position, the wind shield 5 abuts against the first limit column; when the wind shield 5 is located at the windshield position, the wind shield 5 abuts against the second limit column, and the wind shield 5 can no longer rotate, thereby ensuring that the wind shield 5 keeps blocking the outside air.
[0037] When the number of the first limiting column and the second limiting column is one, they are only arranged on one side of the wall of the smoke hood 4; when the number of the first limiting column and the second limiting column is two, the first limiting column and the second limiting column are respectively arranged in pairs on opposite sides of the wall of the smoke hood 4.

[0039] In one embodiment, the exhaust port 42 is composed of a plurality of exhaust holes arranged at intervals along the length direction, which is beneficial to ensure the strength of the wall surface of the smoke hood 4 and prevent deformation.
[0040] In one embodiment, the exhaust port 42 extends outward from the wall surface of the smoke collecting hood 4 in an oblique downward direction. Compared with the vertically arranged exhaust port 42, the oblique exhaust port 42 can increase the exhaust area.
[0041] In one embodiment, the upper wall surface of the smoke hood 4 is spaced apart from the upper wall surface of the chassis 1 to provide a heat insulating effect and reduce the surface temperature of the chassis 1 .
[0042] In one embodiment, the outdoor gas water heater also includes two insulation plates 6, which are installed in the accommodating cavity 11 and are respectively located on the left and right sides of the heat exchanger 3. The insulation plates 6 are spaced apart from the inner wall surface of the chassis 1 to achieve a heat insulation effect and reduce the surface temperature of the chassis 1.
[0043] In one embodiment, the chassis 1 has a built-in handle 13. The handle 13 is provided on the chassis 1, which can be convenient for users to carry outdoors. The built-in handle 13 does not occupy the external space of the chassis 1, which can make the gas water heater more compact and more suitable for outdoor use.
