DETAILED DESCRIPTION

[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. 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.

[0023] Reference below Figures 1 to 5 A bathroom heater structure according to an embodiment of the utility model is described, including a main body shell 1 and a cover plate 2, the cover plate 2 is provided with an air inlet 201 and a blowing outlet 202, a worm fan 5 and a heating device 4 are provided in the main body shell 1, the air inlet 201 is connected with the worm fan 5, an exhaust port 101 is provided on the main body shell 1, an air duct is provided in the main body shell 1, the air duct is divided into an exhaust air duct 104 and a blowing air duct 105, the blowing air duct 105 is connected with the heating device 4, the exhaust air duct 104 is connected with the exhaust port 101, and a hinge 6 for switching the wind direction is provided at the connection between the exhaust air duct 104 and the blowing air duct 105.

[0024] In this structure, air enters from the air inlet 201, and the worm fan 5 rotates to form strong wind. One end of the loose leaf 6 is placed on the inner wall of the main body shell 1 to prevent strong wind from entering the exhaust air duct 104. The strong wind enters the blowing air duct 105 along the loose leaf 6, flows through the heating device 4 on the blowing air duct 105, and the heating device 4 heats the strong wind to form hot strong wind, which is discharged from the blowing port 202. Furthermore, the loose leaf 6 is placed on the side of the blowing air duct 105. At this time, the exhaust air duct 104 is in an open state, and the strong wind is transported from the exhaust air duct 104 to the exhaust port 101. The exhaust port 101 uniformly discharges cold air, which solves the shortcomings of the first volute bellows and the second volute bellows mentioned above. This structure further optimizes the overall structure, thereby reducing the overall volume and reducing the manufacturing cost.

[0025] The movable leaf 6 of the present structure is provided with a motor 3 for driving the movable leaf 6 to swing, and the motor 3 drives the movable leaf 6 to swing, so that the strong wind can only enter the exhaust air duct 104 or the blowing air duct 105, and finally the hot air or cold air is blown out. That is, when the movable leaf 6 closes the exhaust air duct 104, the strong wind can only enter the blowing air duct 105. On the contrary, when the movable leaf 6 closes the blowing air duct 105, the strong wind can only enter the exhaust air duct 104.

[0026] The bottom surface of the heating device 4 of this structure is provided with a mounting frame 401, and the mounting frame 401 is installed with a thermostat 402, and the detection end of the thermostat 402 is placed on the bottom surface of the heating device 4.

The thermostat 402 is connected to the control board, and the control board is respectively connected to the motor 3, the worm gear motor and the heating tube. The control board is a prior art, and the control board setting is not described here.

[0027] In this structure, the cover plate 2 and the motor 3 are connected by screws to fix the position of the motor 3; in this structure, the motor 3 is located on the side of the air outlet 202 to prevent the motor 3 from affecting the air outlet effect.

[0028] In the mainframe housing 1 of the present structure, a guide wall 102 is provided inside, and the hinge 6 is hinged to the guide wall 102. The guide wall 102 has a strong wind guiding function.

[0029] In the main body housing 1 of the present structure, a volute 7 is provided in one side of the volute 7, and a concave position 701 is provided on one side of the volute 7. When the hinge 6 is in a closed state, one end of the hinge 6 is placed in the concave position 701. The concave position 701 limits the position of the hinge 6.

[0030] The heating device 4 of this structure is connected to the cover plate 2 to fix the position of the heating device 4; the heating device 4 corresponds to the air outlet 202.

[0031] The edge of the host shell 1 of the present structure is provided with a shell recess 103, and the edge of the cover plate 2 is provided with a convex position 203. The convex position 203 is placed at the shell recess 103, which can position the cover plate 2 and improve the installation efficiency of the cover plate 2.
