Compared with the resistance wire heating tube, the safety is better, and the heating is uniform and fast. The ceramic electric heating tube is made of alloy wire inside and wrapped in a ceramic block, and the outer shell is wrapped in metal, which is characterized by fast heat transfer and good heat preservation.

Specifically, the air conditioner 100 may further include elements such as an indoor heat exchanger. The indoor heat exchanger is arranged in the casing 1, and the indoor air enters the casing 1 through the indoor air inlet 10 and passes through the indoor heat exchanger after heat exchange. It can be fed into the indoor environment from the air outlet 12 . When the outdoor air needs to be introduced, the fresh air switch 2 opens the fresh air inlet 11 , and the outdoor air enters the casing 1 through the fresh air inlet 11 and is sent into the indoor environment through the fresh air outlet 13 .

When there is no need to introduce fresh air into the indoor environment, the fresh air switch member 2 closes the fresh air inlet 11 to protect the air conditioner 100 to prevent sundries or small animals from entering the casing 1 through the fresh air inlet 11, and also to prevent the backflow of outdoor air. into the case 1.

When the air conditioner 100 operates at a low outdoor ambient temperature, such as in winter, when the fresh air switch 2 opens the fresh air inlet 11 so that outdoor air enters the fresh air inlet 11, the heating device 3 can be operated to heat the outdoor air entering the fresh air inlet 11, The cold air is turned into hot air, so as to prevent the cold and hot air from meeting at the fresh air inlet 11 to generate dew water, thereby preventing the fresh air switch element 2 from being stuck and failing due to freezing of the condensed water. Therefore, when the fresh air function is not required, the fresh air switch member 2 can be normally closed, which prevents cold air from entering the casing 1 and solves the complaint that the fresh air outlet 13 produces condensed water.

According to the air conditioner 100 of the embodiment of the present application, by arranging the heating device 3 on the fresh air switch part 2 , it is possible to avoid the situation that the fresh air switch part 2 is stuck and fails due to freezing of condensation water.

When the second fan is running, the outdoor air can be sucked into the casing 1 from the fresh air inlet 11 and sent into the indoor environment from the fresh air outlet 13 .

Of course, it can be understood that the number of fans is not limited to this, as long as the indoor air can be sucked into the casing 1 from the indoor air inlet 10 and the outdoor air can be sucked into the casing 1 from the fresh air inlet 11. In some embodiments, the air conditioner 100 includes an indoor fan, and the indoor fan is arranged in the casing 1. When the indoor fan is running, the indoor air can be sucked into the casing 1 from the indoor air inlet 10. When the fresh air inlet 11 is opened, the indoor air can be drawn into the casing 1. Outdoor air is sucked into the cabinet 1 through the fresh air inlet 11 .

According to some embodiments of the present application, the air conditioner 100 includes a fresh air component 4 , the fresh air component 4 is provided in the casing 1 , and the fresh air component 4 may include at least one of a fan and a filter assembly. In the specific example of the present application, the fresh air component 4 includes a fan, so that whether to enable the fresh air mode can be independently controlled.
