DETAILED DESCRIPTION

[0020] 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.

[0021] Reference below Figures 1 to 4 A bathroom heater structure with a middle air outlet is described according to an embodiment of the utility model, including a main body shell 2 and a worm turbine fan 3, the worm turbine fan is installed in the main body shell 2, and also includes a cover plate 1, the cover plate 1 is installed on the main body shell 2, the cover plate 1 is provided with a heater mounting port 101 and an air inlet 102, the heater mounting port 101 is installed with a heater 8, the heater mounting port 101 and the air inlet 102 are arranged in the longitudinal axis direction of the cover plate 1, a motor 5 is fixed to the bottom surface of the cover plate 1, the motor 5 is connected to a wind direction conversion valve 9, and the motor 5 drives the wind direction conversion valve 9 to close or open the air inlet on the bottom surface of the heater 8.

[0022] This structure is arranged in the longitudinal direction of the cover plate 1 by locating the heater mounting port 101 and the air inlet 102, which shortens the ventilation path and reduces wind loss, thereby increasing the air output. In addition, the motor 5 drives the wind direction conversion valve 9 to swing, and closes or guides the air inlet of the heater 8. When the wind direction conversion valve 9 swings to the bottom surface of the heater 8, the inlet of the heater 8 is sealed, so that the heater 8 cannot exhaust air; at this time, the heater 8 stops heating. The distance between the heater mounting port 101 and the air inlet 102 is short, and the wind loss can be ignored. The worm wheel fan and the motor 5 are respectively connected to the control panel. The control panel is a prior art, and the specific structure of the control panel is no longer disclosed.

[0023] The worm turbine blower takes in air, and the wind flows out from the air duct in the main engine housing 2. When the wind direction conversion valve 9 leaves the entrance position of the heater 8, the wind flows to the heater 8 and is then discharged from the heater 8. When the strong wind passes through the heater 8, the heating tube in the heater 8 heats the strong wind to form hot wind. Furthermore, the motor 5 is fixed in the main engine housing 2 by screws. Similarly, the worm turbine blower is also installed in the main engine housing 2 by screws, and the main engine housing 2 is correspondingly provided with a screw seat, and the screw is screwed on the screw seat. The screw seat is a prior art and is no longer shown in the attached drawings.

[0024] The upper surface of the heater installation opening 101 of the present structure is provided with an installation frame 103, and the heater 8 is fixed on the installation frame 103. The installation frame 103 is integral with the cover plate 1, the heater installation opening 101 is located in the installation frame 103, and the heater 8 is fixed in the installation frame 103 by screws. A heating pipe is provided in the heater 8, and the heating pipe generates heat, and wind passes through the heating pipe to generate hot air.

[0025] In this structure, the side wall of the host housing 2 is provided with a bayonet 201, and the edge of the cover plate 1 is provided with a buckle head 104, which is buckled on the bayonet 201. The cover plate 1 is fixed on the host housing 2.

[0026] In the present structure, a first air guide plate 6 and a second air guide plate 7 are provided in the mainframe housing 2, a distance is left between the first air guide plate 6 and the second air guide plate 7, a wind direction conversion valve 9 is located between the first air guide plate 6 and the second air guide plate 7, a motor 5 is fixed on the first air guide plate 6, an exhaust port 202 is provided at a corner of the mainframe housing 2, and one end of the first air guide plate 6 extends to the side of the exhaust port 202. When the wind direction conversion valve 9 is placed on the heater 8, the wind turns to the first air guide plate 6 and is discharged from the exhaust port 202.

[0027] In the main body housing 2 of the present structure, a volute 4 is arranged inside, and the volute 4 is formed integrally with the first air guide plate 6. The volute 4 has a guiding function.

[0028] The wind direction conversion valve 9 of this structure has a bent portion on one side.
