Concealed air conditioner indoor unit

Abstract

The invention discloses a concealed air conditioner indoor unit which comprises a casing, a volute, an air outlet frame connected with the volute, a heat exchanger and an electric control box, wherein a centrifugal wind wheel and a motor are arranged in the volute; a water pan is arranged below the heat exchanger; a dust filter gauze is arranged in right front of the heat exchanger; an air inlet of the volute and an air outlet of the indoor unit are formed in the front surface of the unit body; and the heat exchanger is positioned in front of the air inlet of the volute. Air supply channels of the casing and the volute are laterally or vertically arranged, vertical or horizontal indoor units with different front air inlet modes are obtained, and a double volute centrifugal wind wheel fan is vertically or horizontally laid, so that the high power air conditioner indoor unit is obtained. The indoor unit is compact in structural design, small in unit body volume, suitable in installation height, and convenient to install, maintain, dismount and replace, can be horizontally or vertically installed in a concealed way, can also be installed in an open way after a surface frame is provided, and the interior of a unit body can be conveniently cleaned, thereby having a wide installation applicable scope.

Description

technical field [0001] The invention relates to an indoor unit of an air conditioner, in particular to a concealed indoor unit of an air conditioner. Background technique [0002] The mainstream of the existing concealed installed air conditioner indoor units is the air duct unit, which has become the most high-end air conditioner in the minds of consumers due to its advantage of hidden installation. The installation position is relatively high, and there are problems such as poor heating effect of the air conditioner and water leakage and dripping. Since the air duct unit is hidden and installed, the size of the inlet and outlet grille panels is small, and the removal and replacement of the air duct will damage the ceiling decoration of the house, especially the air duct. The grille air outlet of the machine has been open for a long time, and the air supply duct and the inside of the fuselage are easy to enter the dust and breed bacteria and mites. It is very difficult to c...

AI Technical Summary

Problems solved by technology

This installation method will reduce the air volume for the split hanging machine with the cross-flow wind wheel structure, thereby affecting the cooling, heating and energy efficiency of the air conditioner; for the cabinet machine with the centrifugal wind wheel fan structure, due to the volute and The heat exchanger adopts vertically superimposed settings, resulting in the body of the cabinet machine being generally taller and larger in size, and it will take up more space after being hidden and installed.

Moreover, the cabinet machine is limited by the depth of its fuselage, and the inclination angle of the heat exchanger erected above the volute is small, which causes the air volume sent by the volute to blow to different positions of the heat exchanger to be very uneven, affecting the heat exchanger. The heat exchange effect of the air conditioner needs to be enlarged to achieve the nominal capacity and energy efficiency index of the air conditioner
