Air conditioner bottom casing and split type air conditioner indoor machine

Abstract

The invention provides an air conditioner bottom casing. The air conditioner bottom casing comprises a bottom casing body and a volute tongue which is arranged on an upper end surface of an air outlet of the bottom casing body; the volute tongue and the bottom casing body are in an integrated structure; the volute tongue and the bottom casing body are in smooth transition connection on an air outlet side. According to the air conditioner bottom casing, the volute tongue and the bottom casing body which are in the integrated structure are in smooth transition connection on the air outlet side, namely, no clearance or high-low alternating surface exists from the volute tongue to the bottom casing body, the upper end surface of the air outlet is smooth, blocking of air is reduced, air can flow out stably, influence to air flow is reduced, and accordingly the air outlet effect of the air conditioner is improved. The invention also provides a split type air conditioner indoor machine which is provided with the air conditioner bottom casing.

Description

technical field [0001] The invention relates to the technical field of manufacturing a split-type air conditioner inner unit, and more specifically relates to a split-type air conditioner inner unit and its bottom case. Background technique [0002] The split-type air conditioner internal unit mainly includes a bottom shell, a top cover, an evaporator and a fan. The fan will generate noise during operation. Generally, a volute tongue is installed on the upper end of the air outlet to reduce the noise of the fan. At present, the volute tongue and the housing are two separate parts, and the volute tongue needs to be assembled on the bottom case. Based on installation requirements, an installation gap needs to be set on the bottom case. [0003] Since the bottom shell and the volute tongue are two separate parts, after the volute tongue is installed on the bottom shell, there is an installation gap between the volute tongue and the bottom shell, and there are alternating high ...
