As shown in fig. 1, the clothes dryer of the present embodiment includes a cabinet 10 and a cabinet door 20, wherein the cabinet door 20 is rotatably and movably connected to the cabinet 10 through a hinge. Wherein, the shape of the cabinet body 10 can be diversified, preferably cuboid or quasi-cuboid structure, and the structure that can wall-hanging setting is used better.

As a modification of the present embodiment, as shown in fig. 2 and 3, the cabinet 10 should be provided with a clothes drying chamber 30 for hanging clothes and at least one internal circulation duct 40. Preferably, in the present embodiment, two internal circulation air ducts 40 are provided and symmetrically distributed on two sides of the clothes drying chamber 30, which is advantageous in that the air flow in the clothes drying chamber 30 is more uniform and the clothes drying effect is better.

As shown in fig. 3 and 4, in the present embodiment, the clothes drying chamber 30 is provided with an air outlet 12 communicating with the outside. Preferably, in the present embodiment, the air outlet 12 is disposed at the top of the cabinet 10.

In another preferred embodiment, an exhaust fan 70 is disposed near the exhaust port 12, and the exhaust fan 70 can force the air in the clothes drying chamber 30 to be exhausted outwards.

As another possible embodiment, the air outlet may be provided at an internal circulation air duct (not shown) between the internal circulation fan and the heater.

As shown in fig. 3, an internal circulation fan 50 is disposed in the internal circulation air duct 40 of the present embodiment, and it should be noted that the internal circulation fan 50 divides the internal circulation air duct 40 into an air inlet duct 41 and an air outlet duct 42. As shown in fig. 4, the air inlet duct 41 is disposed above the clothes drying cavity 30, the air inlet duct 41 is provided with a plurality of fresh air inlets 11 communicated with the outside, and the outside fresh air enters the air inlet duct 41 through the fresh air inlets 11.

In addition, as shown in fig. 5, the air inlet duct 41 is further provided with a plurality of internal circulation air inlets 33 communicated with the clothes drying chamber 30. Part of the air flow in the drying cavity 30 enters the air inlet duct 41 from the internal circulation air inlet 33.

In this embodiment, the fresh air and the internal circulation air are gathered in the air inlet duct, and after being gathered and passing through the internal circulation fan and the heater, the fresh air and the internal circulation air enter the clothes drying cavity through the air outlet duct.

In this embodiment, as shown in fig. 4 and 5, the air outlet duct 42 is provided with a plurality of air outlet holes 32 communicated with the clothes drying cavity. The air flow in the air inlet duct 41 enters the air outlet duct 42 under the action of the inner circulation fan 50 and enters the clothes drying cavity 30 through the air outlet 32.

As a special feature of this embodiment, as shown in fig. 6, an internal air flow circulation is formed between the air inlet duct, the air outlet duct and the clothes drying chamber, the air inlet path of the fresh air is the fresh air inlet duct, the air outlet duct and the clothes drying chamber, the air flow in the clothes drying chamber partially enters the air inlet duct from the internal circulation air inlet to perform internal circulation, and partially exits from the exhaust port to the outside.

In the air intake mode of this embodiment, the air flow can be realized without forced air intake from the fresh air intake or forced air exhaust from the air exhaust, and in the prior art, the flow and update of the air flow are realized by at least ensuring the forced air intake (setting the air intake fan) or forced air exhaust (setting the air exhaust motor).

In this embodiment, based on the work of inner loop fan, can form local negative pressure in the air inlet duct, the local negative pressure of this department makes the pressure in the air inlet duct be less than external pressure and the pressure in the dry clothing intracavity to external new trend and the air current in the dry clothing intracavity can flow into in the air inlet duct under the effect of local negative pressure. In the process, if the air exhaust fan is not arranged at the air exhaust opening or the air exhaust fan is closed, a positive pressure environment can be formed in the clothes drying cavity under the condition that fresh air continuously enters, the air pressure in the clothes drying cavity is higher than the air pressure in the outside, and the air flow in the clothes drying cavity is automatically discharged to the outside from the air exhaust opening under the action of the positive pressure.

Under the condition that the air exhaust fan is arranged at the air outlet, the positive pressure environment, the negative pressure environment or the normal pressure environment can be formed in the clothes drying cavity by adjusting the rotating speed of the air exhaust fan and the internal circulating fan, so that the selection is more flexible, the air inlet quantity and the air exhaust quantity can be controlled more easily, and the working parameters of the clothes dryer can be adjusted conveniently.

Therefore, in the embodiment, whether the fresh air inlet is provided with the forced air inlet fan or whether the air outlet is provided with the forced air exhaust fan can be selected, the special structural design enables the fresh air inlet, the air flow internal circulation and the air exhaust to be completed only by driving of the internal circulation fan, and the fresh air inlet and air flow internal circulation air exhaust fan has the technical advantages of novel structure and ingenious design concept.
