Wall-mounted air conditioner indoor unit

Abstract

The invention relates to a wall-mounted air conditioner indoor unit. The wall-mounted air conditioner indoor unit comprises a machine shell and a cross-flow fan; the machine shell is provided with anair inlet which is used for introducing air into the machine shell and an air outlet which is used for supplying air into a room, and an air guide plate which is used for adjusting an opening and closing state and/or air outlet direction of the air outlet is arranged at the air outlet; and the cross-flow fan is configured to be arranged in the machine shell in a rotatable mode around a rotating shaft which extends transversely along the machine shell, and comprises a variable-diameter impeller, wherein the radius of the variable-diameter impeller is gradually increased from the transverse twoends of the machine shell to the middle of the machine shell. The air supply amount of the cross-flow fan can be gradually increased from two transverse ends of the machine shell to the middle of themachine shell, so that the air supply amount is the largest in the middle position, and the air supply capacity of the middle area is improved. According to the wall-mounted air conditioner indoor unit, only through one simple design of arranging one cross-flow fan with the variable-diameter impeller only, the effects of strong air supply in the middle area of the air outlet, soft air supply in the two end areas of the air outlet, and the soft transition from the middle area to the two end areas can be achieved, and meanwhile, different requirements of users requiring for instant-cooling and instant-heating effects and users requiring for soft and comfortable effects are met.

Description

technical field [0001] The invention relates to an air conditioner, in particular to a wall-mounted air conditioner indoor unit. Background technique [0002] More and more people are pursuing a refined and tasteful life, whether in homes or offices, air-conditioning indoor units have become a necessity in people's lives. The traditional wall-mounted air conditioner indoor unit has a single appearance, and the limitation of shape change limits the improvement of air conditioner performance to a certain extent. [0003] The wind speed and wind temperature in each area sent by the same ordinary air-conditioning indoor unit are basically the same. However, due to differences in gender, age, and physical fitness, different people in the same room have different sensitivities to temperature and wind speed. , And then lead to differences due to issues such as the temperature and gear of the air conditioner. [0004] In addition, the indoor unit of the air conditioner achieves th...
