Problems solved by technology

The basic idea of ​​these two patents is to use the air supply duct to prevent the noise generated by the compressor from being introduced into the air-conditioning room
However, this does not solve the problem of further reducing noise and improving air supply comfort in existing split air conditioners

Embodiment Construction

[0020] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0021] Such as figure 1 As shown, the present invention includes an outdoor unit 1, an evaporator 2, an indoor unit fan 3, an indoor unit casing 4, a porous damper blade 5, a damper motor connecting shaft 6, a damper motor 7, and an indoor unit air return port 8.

[0022] The indoor unit return air outlet 8 is positioned at the front upper part of the indoor unit casing 4, and the evaporator 2 is installed in the indoor unit casing 4 near the indoor unit return air outlet, and the indoor unit fan 3 is positioned at the rear lower part of the evaporator 2. The damper motor 7 is installed on the bottom of the indoor unit shell 4, and is connected with the porous damper blade 5 through the damper motor connecting shaft 6. When the damper motor 7 rotates, the porous damper blade 5 can be rotated. The outlet of the outdoor unit 1 is connecte...

Abstract

Multimode of air feed silent separate type room air conditioner belongs to the refrigeration and air conditioning technical field, comprising outer room machine, evaporator, inner room machine blower fan, multihole blower fan vane, blower fan electric machine connecting shaft, blower fan electric machine, inner room machine air inlet. In addition to using foamed metal as the material of multihole blower fan vane, in addition of two varieties of air blast pattern are included: 1) mute scattering air blast pattern. The running noise of inner room machine air blast is isolated basically, and the air current flows out from multihole blower fan vane; 2) mixed air blast pattern. A part of air current penetrates the multihole blower fan vane, another part of flows out through the space between the inner room machine and the shell. The invention with the function of mute scattering air blast patterncan decrease the noise five db, and avoiding air current with high speed blows straightly towards people, and the mixed air blast pattern can ensure comfort and silence as well as amount of blast.

Description

Technical field: [0001] The invention relates to a room air conditioner, in particular to a quiet split-type room air conditioner with multiple air supply modes, which can reduce noise and improve comfort, and belongs to the technical field of refrigeration and air conditioning. Background technique: [0002] Room air conditioners generally guide the flow of air through the guiding function of the damper. When the air conditioner is in a normal operating state, the cold air will flow to the room in a certain direction. At this time, the place directly blown by the cold air has a lower temperature, and the cooling effect of the rest of the space is poor. In order to save the power consumption of the air conditioner, the air blowing direction of the general air conditioner is directed to the area where the human body moves. However, if a person changes from an active state to rest, especially during sleep, if there is air with a lower temperature and a higher velocity flowing...
