Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to a vertical air conditioning indoor unit. Background Art

[0002] The vertical air conditioner indoor unit may include an indoor air inlet, an indoor air outlet, an indoor heat exchanger and an indoor fan. The indoor fan drives the air from the indoor air inlet into the air conditioner indoor unit to exchange heat with the indoor heat exchanger. The heat-exchanged air flows out of the air conditioner indoor unit through the indoor air outlet to cool or heat the environment.

[0003] At present, there are two main types of existing vertical air-conditioning indoor units, one of which is a traditional single-flow indoor unit. The traditional single-flow indoor unit includes a casing and a cross-flow fan, which is arranged in the casing. The casing is provided with an air inlet and an air outlet, and generally has one air inlet, which is generally arranged at the rear side of the casing, and has one air outlet, which is arranged forward. However, the wind blown out from the air outlet from top to bottom is the same, and the wind feeling is strong, the user's wind feeling experience is poor, and it is difficult to meet the user's demand for multiple air outlets. In order to improve the user's wind feeling experience and make up for the deficiency that the traditional single-flow indoor unit can only discharge air from the front side, a front side air outlet is opened on the casing, and a side air outlet arranged on the side of the casing is opened on the casing, and in order to make the side air outlet discharge air normally, a corresponding side air outlet duct is also provided, and in order to ensure the normal air outlet of the side air outlet, the side air outlet duct is also equipped with a corresponding side air outlet fan.

[0004] However, this kind of indoor unit with multiple air ducts and multiple air outlets needs to be equipped with a large number of fans, and the fans arranged in the side air outlet ducts are generally centrifugal fans or axial flow fans, which seriously increases the cost of the vertical air conditioner indoor unit, and the centrifugal fans and axial flow fans are noisy and the air supply distance is not far enough; and when there are many air outlets, in order to realize multiple air outlets, the air outlet ducts are relatively complex, which increases the design and manufacturing costs, and there are also many problems with the air outlet smoothness of the air outlet ducts, which makes the air outlet resistance large, and it is difficult to ensure the air volume of each side air outlet, resulting in poor user experience; and when the fan, air duct and air outlet are not designed reasonably, the air outlet distance is short and it is easy to produce a windless area at the air outlet, which affects the user experience. Therefore, a vertical air conditioner indoor unit is proposed. Summary of the invention

[0099] In the present application, the indoor air inlet 111 may be disposed at the rear side of the casing.

[0100] In the present application, the indoor air inlet 111 may be in communication with the first cavity.

[0101] In the present application, an indoor air outlet may be formed on the housing 1. The indoor air outlet may be an outlet for air to flow out of the housing 1.

The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the whole cycle, the air conditioner can adjust the temperature of the indoor space.
