The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0024] Reference below Figures 1 to 5 A vertical bathroom heater according to an embodiment of the utility model is described, including a body shell, a motor 2 and a worm gear 3, the motor 2 and the worm gear 3 are connected and the motor 2 is fixed in the body shell, the body shell is in a long strip shape, and the body shell is respectively provided with an exhaust port 8, a blowing port and an air inlet, the blowing port and the air inlet are located on the same side, the blowing port is installed with an electric heater 6, and a valve motor 406, a first limiting portion 403 and a second limiting portion 404 are also provided in the body shell, the valve motor 406 is connected to a valve plate 5, and the valve plate 5 is located between the first limiting portion 403 and the second limiting portion 404.

[0025] This structure further compresses the overall volume by making the body shell in an elongated strip shape, making the body shell suitable for installation in a specific installation environment; in addition, the combination of the first limiting portion 403 and the second limiting portion 404 serves to limit the range of movement of the valve plate 5 to avoid the valve plate 5 from getting stuck, that is, to avoid the valve plate 5 from coming into hard contact with the inner wall of the body shell, making it impossible for the valve plate 5 and the inner wall of the body shell to be separated, resulting in a stuck phenomenon.

[0026] The working principle of this structure is as follows: the motor 2 drives the worm gear 3 to rotate to generate strong wind, and the strong wind output passes through the inner cavity of the body shell and enters the vicinity of the valve body 5; wherein, the valve motor 406 drives the valve plate 5 to move to the first limit portion 403, and the strong wind enters the range of the electric heater 6, and the electric heater 6 heats the strong wind and discharges the hot strong wind through the electric heater 6. In addition, when the valve plate 5 moves to the second limit portion 404, the valve plate 5 closes the blowing port, the electric heater 6 stops heating, and the strong wind is discharged from the exhaust port 8, implementing cold air outlet.

[0027] The electric heater 6 is composed of a heat sink and a heating tube, or a heat sink and a PTC heating sheet. The heating tube and the PTC heating sheet play a heating role and heat the heat sink. When the strong wind passes through the heat sink, heat exchange is performed, and the strong wind is heated and converted into hot strong wind. The angle between the exhaust port 8 and the blowing port is preferably 90 degrees.

[0028] The valve motor 406 is fixed to the inner wall of the housing by screws or by gluing, and the rotating shaft of the valve motor 406 is fixedly connected to one side of the valve plate 5.

[0029] The housing of the present structure is provided with a second air guide 7, one end of which extends to the air outlet, and the other end of which extends to the valve motor 406. A C-shaped portion is provided on the other end of the second air guide 7, and the hinge 501 is disposed at the C-shaped portion to limit the position of the valve plate 5 and enhance the stability of the valve motor 406 driving the valve plate 5 to swing.

[0030] The second air guide piece 7 is in an arc shape, which plays an effective role in guiding the wind, so that strong wind can be blown to the electric heater 6. In addition, the air outlet of the present structure is provided with a positioning portion 402, and one side of the positioning portion 402 is placed on the electric heater 6. The positioning portion 402 limits the position of the electric heater 6, and the positioning portion 402 is in a triangular shape. The number of positioning portions 402 is preferably three, and the positioning portion 402 is placed on the edge of the electric heater 6. Figure 4 and Figure 5 As shown, the valve plate 5 is in a state of closing the air outlet.

[0031] The body shell of the present structure includes an upper body shell 1 and a lower body shell 4, and a motor mounting recess 101 is provided on the surface of the upper body shell 1. The motor 2 of the present structure is located on the motor mounting recess 101, and the motor 2 is connected to the motor mounting recess 101 by screws, which facilitates the fixing of the motor 2, and the screws are not exposed in the motor mounting recess 101. The upper body shell 1 and the lower body shell 4 can be connected by screws, or by buckling. The screw connection method or the buckling method are both prior arts, and the relevant structure is not disclosed here.

[0032] The air inlet of this structure is divided into an upper air inlet 102 and a lower air inlet 401.

[0034] In this structure, the first limiting portion 403 and the second limiting portion 404 are distributed at an angle, so as to limit the valve plate 5 from swinging between the first limiting portion 403 and the second limiting portion 404 . Both the first limiting portion 403 and the second limiting portion 404 are arc-shaped, which are compatible with the shape of the valve plate 5 .

[0035] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
