Those skilled in the art can make adjustments as needed so as to adapt to specific applications.

Secondly, it should be noted that, in the description of the present invention, terms such as "inner", "outer" and other indicated directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description. It is not intended to indicate or imply that a device or component must have a particular orientation, be constructed or operate in a particular orientation, and thus should not be construed as limiting the invention.

In addition, it should be noted that, in the description of the present invention, unless otherwise specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection , or integrally connected; it can be mechanically connected or electrically connected; it can be directly connected or indirectly connected through an intermediary, and it can be the internal communication of two components. Those skilled in the art can understand the specific meanings of the above terms in the present invention according to specific situations.

A cabinet-type air conditioner in the related art, the indoor unit includes a casing and a cross-flow fan part arranged inside the casing. The casing is provided with an air-conditioning air inlet and an air-conditioning outlet. Inside the wind wheel, the fan casing has a fan air inlet opposite to the air conditioner air inlet, and a trumpet-shaped fan outlet. When the wheel rotates, indoor air enters the fan casing from the air inlet of the air conditioner through the air inlet of the fan, and is discharged from the air outlet of the air conditioner through the air outlet of the fan to form an air flow. However, when the speed of the airflow at the large end opening of the fan outlet duct is close to or equal to zero, due to the high air pressure outside the fan casing facing the fan outlet duct, the air outside the fan casing will be affected by the pressure difference. Entering the inside of the fan casing from the outlet of the fan, there is a problem of back-suction. At the same time, the airflow generates a vortex in the wind wheel, and the back-suction will change the flow of the airflow, causing the center of the vortex to move from the first position to The second position, and the movement of the center of the vortex from the first position to the second position will change the flow of the airflow again, causing the center of the vortex to move from the second position to the first position, and it goes round and round.

In the cabinet-type air conditioner indoor unit of the present invention, the fan casing 201 is also provided with a shielding part 212 located in the fan outlet duct 205 and close to the big end opening. The actual air outlet area increases the wind speed of the airflow at the large end opening of the fan outlet duct 205, reduces the probability that the airflow at the large end opening of the fan outlet duct 205 has a zero wind speed, and then reduces the wind speed of the fan casing 201. The probability that the high-pressure air outside enters the installation cavity 204 from the fan outlet channel 205 under the action of the air pressure difference makes the air output of the fan outlet stable and uniform.

In the cabinet-type air conditioner indoor unit of the present invention, the large end opening of the fan air outlet 205 is arranged opposite to the air outlet of the air conditioner, and the fan casing 201 is provided with a shielding portion 212 located at the fan air outlet 205, which can also improve the front panel. Condensation problem.

An embodiment of the present invention also provides a cabinet-type air conditioner, which includes the above-mentioned cabinet-type air conditioner indoor unit and a cabinet-type air conditioner outdoor unit used in conjunction with the cabinet-type air conditioner indoor unit.

The cabinet-type air conditioner in the embodiment of the present invention is provided with the above-mentioned cabinet-type air conditioner indoor unit, therefore, the shielding part 212 reduces the actual air outlet area of the large end opening of the fan outlet duct 205, and increases the air flow in the air outlet of the fan. The wind speed at the big end opening of the duct 205 reduces the probability that the wind speed is zero at the big end opening of the air outlet duct 205 of the fan, thereby reducing the pressure of the high pressure air outside the fan casing 201 from the blower fan under the action of the air pressure difference. The probability that the air outlet channel 205 enters the installation cavity 204 makes the air output of the air outlet of the fan stable and uniform.

So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings, but those skilled in the art will easily understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present invention.
