Indoor unit of air conditioner and air conditioner

Abstract

The invention discloses an indoor unit of the air conditioner and the air conditioner. The indoor unit of the air conditioner comprises a shell, an air channel structure and a plurality of elastic reset devices. An arrangement cavity is formed in the shell. The shell comprises a back plate, a containing frame and a partition plate. The back plate extends in the vertical direction. The containing frame comprises a baffle and a supporting plate, wherein the baffle extends frontwards and downwards from the lower edge of the back plate, and the supporting plate extends backwards from the lower edge of the baffle. The partition plate is located in a gap of the baffle. The partition plate cooperates with the containing frame to form a containing cavity on the side with the back towards the arrangement cavity. The air channel structure is detachably arranged on the lower portion of the arrangement cavity. The upper portion of the air channel structure is provided with an air inlet connected with a heat exchanger of an indoor unit of the air conditioner and the lower portion of the air channel structure is provided with an air outlet. The air outlet structure extends from the upper side to the front side and the lower side in the shape of an arc protruding backwards. The elastic reset devices are connected with the partition plate and the back plate elastically, so that the partition plate abuts against the air channel structure, and assembly and disassembly of the air channel structure are guided. After the air channel structure is installed in place or retreats from the arrangement cavity, the elastic reset devices enable the partition plate to reset. The structural reliability of the indoor unit of the air conditioner can be improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an indoor unit of an air conditioner and an air conditioner. Background technique [0002] The indoor unit of the air conditioner is used to adjust the indoor temperature. The indoor unit of the air conditioner generally has an indoor heat exchanger and a wind wheel assembly, wherein the wind wheel assembly is used to drive airflow to flow through the indoor heat exchanger. The wind wheel assembly of the indoor unit of the air conditioner with a detachable air duct structure is arranged in the air duct structure and installed along with the air duct structure. [0003] The air duct structure of the existing air conditioner indoor unit is easy to scratch the refrigerant input and output pipes and / or drain pipes arranged on the back of the air conditioner indoor unit during the disassembly process. Partitions are provided between and / or drain pipes to form protection when...

AI Technical Summary

Problems solved by technology

The air duct structure extrudes the partition to cause elastic deformation of the partition, creating a space for the smooth installation of the air duct structure into the shell. However, due to the insufficient strength of the partition itself, especially the partition of plastic parts, the Plastic deformation and even fatigue fracture are prone to occur during the extrusion process of the road structure

Therefore, the structural reliability of the indoor unit of the air conditioner is insufficient
