Embodiment 1

[0047] First refer to Figure 1 to Figure 4 , to describe the hanging angle air conditioner indoor unit of the present invention. in, figure 1 It is a schematic diagram of the installation position of the hanging angle air conditioner indoor unit in the first embodiment of the present invention, figure 2 It is a schematic diagram of the appearance of the hanging angle air conditioner indoor unit in the first embodiment of the present invention, image 3 for figure 2 The cross-sectional view at A-A in the middle, Figure 4 for figure 2 Partial enlarged view of B in the center.

[0048] Such as Figure 1 to Figure 4 As shown, in order to solve the problem that when the existing hanging angle air conditioner indoor unit needs a large air volume output, the blower 4 rotates too high and generates relatively large noise, the hanging angle air conditioner indoor unit of the present invention includes a shell 1, and a There is an air inlet 11 and an air outlet 12, and a hea...

Embodiment 2

[0072] Refer below Figure 10 , to describe the second embodiment of the present invention, wherein, Figure 10 It is a sectional view of the hanging angle air conditioner indoor unit in the second embodiment of the present invention.

[0073] Such as Figure 10 As shown, on the premise that the other setting methods of Embodiment 1 remain unchanged, the indoor unit of the hanging angle air conditioner of the present invention may not be provided with a fresh air duct 7, an air guide groove 6 and a purification module 8, but directly uses indoor air for replenishment. Wind, indoor air enters the supplementary air channel 15 through the supplementary air inlet 14, then enters the heat exchange channel 13, and is mixed with the heat exchanged air to blow out the hanging angle air conditioner indoor unit together. Such a setting method can also reduce the noise generated by the indoor unit of the air conditioner, but it does not have the functions of fresh air and purification....

Embodiment 3

[0075] Refer below Figure 11 , to describe the third embodiment of the present invention, wherein, Figure 11 It is a cross-sectional view of the hanging angle air conditioner indoor unit in the third embodiment of the present invention.

[0076] Such as Figure 11 As shown, on the premise that the other setting methods of Embodiment 1 remain unchanged, the indoor unit of the hanging angle air conditioner of the present invention may not be provided with the fresh air duct 7 and the air guide groove 6, but directly uses indoor air for supplementary air, and the indoor air It enters the supplementary air channel 15 through the supplementary air inlet 14, and then enters the heat exchange channel 13 after being purified by the purification module 8, and is mixed with the heat exchanged air to blow out the hanging angle air conditioner indoor unit together. Such a setting method can also reduce the noise generated by the indoor unit of the air conditioner, but it does not have...

Abstract

The invention belongs to the field of air conditioners and particularly provides an indoor unit of an overhang angle air conditioner, aiming at solving the problem that relatively great noises are generated due to an over-high rotary speed of a forced draught blower when high air flow output is needed by an existing indoor unit of the overhang angle air conditioner. The indoor unit of the overhangangle air conditioner comprises a shell, wherein an air inlet and an air outlet are formed in the shell; a heat exchange channel is formed between the air inlet and the air outlet; and a heat exchanger and the forced draught blower are arranged in the heat exchange channel. The shell is further provided with an air supplementation inlet; an air supplementation channel is formed between the air supplementation inlet and the heat exchange channel; an air supplementation machine is arranged in the air supplementation channel; the overhang angle air conditioner further comprises a fresh air pipe;and a first end part of the fresh air pipe is connected with the air supplementation inlet and a second end part of the fresh air pipe communicates with the outside. According to the indoor unit of the overhang angle air conditioner, the air supplementation channel is arranged and the air conveying rotary speed of the forced draught blower is reduced, so that the noises are reduced.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides a hanging angle air conditioner indoor unit. Background technique [0002] With the improvement of living standards, people's requirements for the quality of life are getting higher and higher, and this requirement is particularly evident in household appliances. Taking air conditioners as an example, when the indoor and outdoor temperature difference is large, in order to meet the needs of users for rapid cooling / heating after entering the room from the outside, the existing air conditioners usually have a rapid cooling / heating function. When functioning, the compressor of the air conditioner works at a higher frequency to quickly increase the cooling capacity / heating capacity, and the indoor unit of the air conditioner runs at a high speed and a large air volume to send the heat-exchanged cold air / hot air back to the room, thereby realizing indoor cooling. Qu...
