The utility model provides a wall-mounted air conditioner indoor unit.

In the embodiment of the present invention, as shown in fig. 1 to 3, the wall-mounted air conditioner indoor unit includes a casing 10 and a purification module 20. Wherein, the casing 10 has a heat exchange air duct (not labeled), the top of the casing 10 is provided with a main air inlet 11 communicated with the heat exchange air duct, and the purification module 20 is installed at the main air inlet 11. The housing 10 further has two side surfaces (not shown) extending in the up-down direction, and at least one side surface is provided with an auxiliary air inlet 12, and the auxiliary air inlet 12 is communicated with the heat exchange channel.

In general, a wall-mounted air conditioning indoor unit has a rectangular parallelepiped body, and is installed with one side thereof attached to a wall and the other side thereof facing the inside of a room, and with the side thereof facing the inside of the room being a front side of the body and the side thereof attached to the wall being both sides, both side surfaces of the casing 10 extending in the vertical direction can be obtained with reference to this.

It can be understood that, in a typical wall-mounted air conditioner indoor unit, the purification module is installed at the air inlet of the body to purify the indoor air. Because the air permeability of the purification module is poor, the purification module is arranged at the air inlet of the indoor unit, the wind resistance of the air inlet can be increased, the air inlet volume loss of the air inlet is serious, and the working power of the indoor unit of the air conditioner can be improved to ensure the air outlet volume, so that the working noise is increased. To the above problem, the utility model discloses technical scheme sets up supplementary air intake 12 through at least one side surface at casing 10 to make this supplementary air intake 12 and heat transfer wind channel intercommunication, so, at the air conditioning indoor set during operation, the air can be simultaneously from main air intake 11 and supplementary air intake 12 inflow casing 10, the air that flows in through main air intake 11 can be purified by purification module 20, and play the effect of formaldehyde in the clean room, and through the air of supplementary air intake 12 inflow, then can compensate the indoor set because of the amount of wind loss that purification module 20 caused. Therefore, the air outlet quantity of the indoor unit of the air conditioner can be ensured only by slightly increasing the power or without increasing the power, so that the working noise is reduced. It is thus clear that compare in common air conditioning indoor set, the wall-hanging air conditioning indoor set of this application has the air loss and is few, and noise at work is little advantage. Meanwhile, since the auxiliary air inlet 12 is directly formed in the side surface of the casing 10, compared with the conventional air conditioning indoor unit, the structure is less modified, additional parts are not required to be added, and the assembly is convenient; and theoretically the service life of the auxiliary air inlet 12 is the same as that of the main air inlet 11. The wall-mounted air conditioner indoor unit has the advantages of simple structure, convenience in assembly and long service life. Alternatively, in this embodiment, the purification module 20 is a formaldehyde purification module, which is one of air purification modules, and is generally composed of a filter screen (filter element) with physical adsorption capacity or an electrostatic adsorption-capacity filter element, and may also be composed of an ion adsorption-capacity filter element. Of course, in other embodiments of the present application, the purification module 20 may be configured as other modules, such as a dust filter module.

Optionally, in the present embodiment, both side surfaces of the housing 10 are provided with the auxiliary air inlets 12. The advantages of providing the auxiliary air inlets 12 on both side surfaces of the housing 10 are as follows: firstly, when the air passing area of the auxiliary air inlet 12 on one side surface of the shell 10 is fixed, the auxiliary air inlets 12 are arranged on both side surfaces of the shell 10, so that the air inlet volume of the indoor unit obtained through the auxiliary air inlets 12 can be increased, and the air volume loss of the indoor unit caused by the purification module 20 can be made up to the maximum extent; secondly, when the air quantity from the auxiliary air inlet 12 required by the indoor unit is constant, compared with the mode that the auxiliary air inlet 12 is only arranged on one side surface of the shell 10, the auxiliary air inlets 12 are arranged on the two side surfaces of the shell 10, so that the air passing area of the auxiliary air inlet 12 on the single side surface of the shell 10 can be reduced, the opening on the single side surface of the shell 10 is reduced, and the attractiveness of the indoor unit is improved; in addition, the auxiliary air inlets 12 are formed in the surfaces of the two sides of the casing 10, so that the casing 10 has a more symmetrical structure, and the attractiveness of the indoor unit is improved. Of course, the design of the present application is not limited thereto, and in other embodiments of the present application, the auxiliary intake vent 12 may be provided only on one side surface of the housing 10.

Optionally, in the present embodiment, the auxiliary air inlet 12 is located on the front side of the heat exchanger 30 of the wall-mounted air conditioning indoor unit.
