[0019] The present utility model will be further described below in conjunction with the accompanying drawings: As shown in the figure, a hand dryer with high thermal efficiency includes a housing 1. A blower 2 and a heating element 3 are provided inside the housing. An air outlet 11 is provided on the housing. It further includes a wind gathering channel 12. One end of the wind gathering channel is arranged opposite to the blower, and the other end is arranged opposite to the air outlet. A wind gathering shell 14 that reduces the cross-sectional area of the wind gathering channel is provided in the middle of the wind gathering channel. The heating element is installed on the wind gathering shell, and a through groove 31 for the wind to pass through is provided on the heating element. In a conventional air outlet channel, since the heating element itself is relatively small and the air outlet is relatively large, the wind generated by the blower cannot completely pass through the heating element, resulting in low thermal efficiency. In this application, the middle of the wind gathering channel has a relatively small structure (here referring to the cross-sectional area), and the heating element is installed here, enabling the wind to completely pass through the heating element. A wind passage is provided on the heating element to improve the heating efficiency of the wind.

[0020] In this embodiment, as shown in the figure, there are two or more air outlets. It can blow air from both sides.

[0021] In this embodiment, as shown in the figure, a wind hood 13 is provided inside the housing. The wind hood is communicated with the air outlet, and the wind generated by the blower is communicated with the wind hood through a ventilation pipe 21. By being communicated through a branch pipe, the escape of wind can be prevented, and the wind can better enter the wind hood.

[0022] In this embodiment, as shown in the figure, the wind gathering shell is detachably installed inside the wind hood.

[0023] In this embodiment, as shown in the figure, an installation groove 141 is provided on the wind gathering shell, and the heating element is installed in the installation groove. The heating element can be a heating resistor, etc., and it can be installed in the installation groove by means of snap connection, bonding, etc.

[0024] In this embodiment, as shown in the figure, the air-gathering housing includes a mounting base 140. An installation groove is provided in the mounting base. A plurality of hooks 142 are provided on the mounting base. The hooks are correspondingly arranged on the outer end face of the heating element to prevent the heating element from falling out. After the heating element is installed, it is fixed by the hooks to prevent it from falling out, and the installation is relatively convenient.

[0025] In this embodiment, as shown in the figure, the air-gathering housing includes a baffle 143. Part of the baffle contacts the inner wall of the wind hood to block the wind generated by the fan and make it pass through the heating element. The baffle is used to block and reduce the cross-sectional area of the air-gathering channel, and it contacts the inner wall of the air-gathering channel.

[0026] In this embodiment, as shown in the figure, the air-gathering housing includes a baffle. Part of the baffle contacts the inner wall of the air-gathering channel to block the wind generated by the fan and make it pass through the heating element. It is also possible not to require an air-gathering hood. In relatively simple cases, the air-gathering housing can be directly installed in the hand dryer housing to reduce the cross-sectional area. The installation can be achieved by using the screw mounting holes of the baffle in cooperation with screws.
