BACKGROUND

Water heater is a commonly-used household electrical appliance. With the popularization of outdoor sports, portable water heaters have emerged. Most of the existing portable water heaters are gas water heaters, which include a burner and a heat exchanger at an upper end of the burner, and it is needed to arrange a fume hood at an upper side of the burner to discharge the fume produced by the burner. For outdoor applications, it is necessary to prevent wind from entering the burner through the hood, and thus a rotatable air deflector is needed to be arranged inside the hood. In the prior art, a rotating shaft transversely goes through the air deflector to be connected with a side wall of the hood. In this structure, the rotating shaft may hinder the air flow on the air deflector, which may cause a problem that the air deflector cannot rotate automatically. In addition, the connection strength between the hood and the heat exchanger is not enough, such that the hood is prone to be detached from the heat exchanger.

Referring to FIGS. 1-2, the present disclosure provides a fume hood structure for portable water heaters, including a hood body 1. The hood body 1 includes a top plate 11 and two side plates 12 respectively located at two sides of the top plate 11. An interior of the hood body 1 is transversely provided with an air deflector 3 which is rotatable. Two ends of the air deflector 3 are each provided with a rotating lug 41. The two side plates 12 are each provided with a rotating shaft base 2. The rotating shaft base 2 is provided with a rotating shaft 21, and the rotating shaft 21 is configured to extend inwardly and transversely from the rotating shaft base 2, and is insertedly connected with the rotating lug 41.

In an embodiment, the air deflector 3 is directly connected with the rotating shaft 21 through the rotating lug 41. Therefore, an installation of the air deflector 3 is convenient. There is no blocking structure on the surface of the air deflector 3, such that the rotation of the air deflector 3 will not be affected.

In an embodiment, the air deflector 3 can rotate up and down around the rotating shaft 21. A normal state of the air deflector 3 is open, that is, a smoke discharging state, which the air deflector 3 rotates upward. When the wind is blown from outside to the fume hood, a side of the air deflector 3, which is also a windward side, is closed, and the other side of the air deflector 3 is open, so as to prevent the outside wind from entering the fume hood.

In order to prevent the outside wind from passing over the air deflector 3, a first side of the air deflector 3 rotates downward, and an upper side of a middle of the air deflector 3 is provided with an upper baffle connected with the top plate 11.

In order to facilitate to install and fix the fume hood, a lower end of each of the two side plates 12 is provided with a flanging part 13 extending inward. A first support plate and a second support plate are both connected between two flanging parts 13 of the two side plates 12, and the first support plate is opposite to the second support plate. Two ends of each of the first support plate and the second support plate 5 are each provided with an extension part 51 arranged on an upper side of the flanging part 13. And a lower end of the hood body 1 can be strengthened and fixed through the first support plate and the second support plate 5, which is convenient to install and fix a heat exchanger.

In an embodiment, a middle part of the two flanging parts 13 is provided with a limiting plate 14 extending downward, and the first support plate and the second support plate 5 abuts against two limiting plates 14 to form a rectangular mounting structure. The rectangular mounting structure has a high strength and can satisfy mounting needs.
