Description

[ field of technology ]

The utility model belongs to the technical field of air conditioners, and particularly relates to an air conditioner evaporator sealing structure and an air conditioner.

[ background Art ]

The evaporator assembly may cause slight deformation in the shape of the evaporator due to manufacturing tolerances or assembly stresses; the chassis of the air conditioner is usually made of plastic materials, and the chassis is deformed due to temperature change in the working process of the air conditioner in the injection molding production process. There is typically a large assembly gap between the evaporator and the air conditioner chassis.

The sealing between the evaporator and the air conditioner chassis is mainly used for preventing air which is not cooled by the evaporator from entering an air duct of the air conditioner. If air which is not cooled by the evaporator exists, the air enters an air duct of the air conditioner through an assembly gap between the evaporator and the air conditioner chassis, and the following problems can occur: 1. in the air which is not cooled by the evaporator, the water content is higher and the temperature is higher. Under the working conditions of air conditioner refrigeration and dehumidification, the temperature in the air channel of the air conditioner is much lower than the temperature of air outside the machine. The air which is not cooled by the evaporator enters the air duct, and the moisture in the uncooled air can be continuously understood on the inner wall of the low-temperature air duct and in the continuously rotating cross-flow fan in the air duct due to the large temperature difference, so that the quality problems of water blowing at the air outlet of the air conditioner, water dripping of the outer shell of the whole machine and the like are finally caused. 2.
