Detailed ways

In order to make the above objectives, features and advantages of the present disclosure more comprehensible, specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

There are cross-flow fan blades in the air conditioner. The cross-flow fan blades are driven to rotate by a large motor. Since the air conditioner generates condensed water during heat exchange, a motor cover is generally placed on the large motor to prevent the large motor from getting wet; Installed above the cross-flow fan, one end of the evaporator is supported by the motor cover, but most of the air conditioners require constant handling and long-distance transportation before they reach the customer. Because the evaporator and the motor cover are not fixedly connected to each other, It is easy to cause collision between the evaporator and the motor cover during handling and transportation.

Therefore, as shown in FIGS. 1 and 2, an embodiment of the present disclosure provides an evaporator fixing structure, including an evaporator 701 and a motor cover 702. The evaporator 701 is provided with a fixing ear 703, and the motor cover 702 is provided with a fixing portion 704. , The fixing portion 704 is connected to the fixing ear 703.

Among them, the motor cover 702 is generally set on the right side of the evaporator 701, the evaporator 701 is installed on the base, and the base is provided with a motor that drives the cross-flow fan to rotate. The motor cover 702 is installed between the evaporator 701 and the motor, which can To support the evaporator 701; the fixing part 704 is arranged on the front side of the motor cover 702, the position of the fixing ear 703 corresponds to the position of the fixing part 704, the fixing ear 703 and the evaporator 701 are fixedly connected, the fixing part 704 The connection with the fixing ear 703 may be a snap connection, a screw connection or a welding, so that the evaporator 701 and the motor cover 702 are fixedly connected to each other. The above orientation description is defined according to the location where the air conditioner is installed in actual use.
