Therefore, it is necessary to design a wall-mounted dryer with a heating function to solve the above problems.

Therefore, the Chinese utility model patent specification (grant publication number: CN 206157424U) discloses a wall-mounted clothes dryer with a heating function. It includes outer container, upper cover, the outer container upper end is provided with the upper cover, upper cover upper surface edge is provided with the hanging support, an upper cover side is provided with cable joint and power cord, the inside temperature control needle that is provided with in another side upper end, upper cover another side middle part is provided with temperature detect switch, upper cover another side lower extreme is provided with switch, the inboard lower extreme of upper cover is provided with the water receiving box, the water receiving box upper end is provided with the manger plate and looses the wind box, the water receiving box lower extreme is provided with the fixed plate, the inside PTC heating element that is provided with of fixed plate, the fixed plate lower extreme is provided with the crossflow fan. When the temperature control switch is operated by an operator to set a temperature value, the PTC heater starts to work, and at the moment, the air outlet discharges hot air.

In practical use, we have found that the above products have the following drawbacks:

1. Because the air inlet is arranged below the air outlet, the air outlet is arranged above the air inlet, and therefore the energy consumption of the fan is relatively large.

2. The wind power of the wind outlet system is small, and if the wind power needs to be increased, the rotating speed of the cross flow fan needs to be increased, so that the energy consumption is further increased.

3. When the crossflow fan is used and rotated, the outer box is driven to vibrate together, the noise is high, and the use experience is poor.
