Abstract
The utility model relates to a split type air conditioner (wall built-up machine), especially relate to an air conditioner with trade fresh air function. The indoor unit of the split air conditioner comprises a shell, an air inlet and an air outlet are arranged on the shell; the multiple groups of inertial flow fan blades are driven by the motor to rotate; the evaporator is positioned above the inertial flow fan blade; the device also comprises a fresh air exchange fan blade and a fresh air exchange pipe; the fresh air replacing pipe is positioned on an air outlet channel of the fresh air replacing fan blade and is communicated with the outside. The fresh air replacing function is realized by newly adding the fresh air replacing fan blade and the fresh air replacing pipe and guiding out the indoor air outdoors, and a large amount of cost is saved without an additional fan and a motor.
Description
Technical Field
The invention relates to a split air conditioner (wall-mounted machine), in particular to an air conditioner with a fresh air exchange function.
Background
In order to provide a comfortable indoor environment to users, air conditioners generally perform a refrigeration cycle using components such as a compressor, a condenser, and an evaporator to control the temperature of the air or purify the air in a city, but when a closed room is cooled or heated for a long time, the air in the room becomes turbid, which may adversely affect the health of the users, and thus it is necessary to perform periodic ventilation of the room. As is known, although air conditioners which do not ventilate for a long time can cause a plurality of syndromes related to the air conditioners, the environment of opening the air conditioners is opened to open the air conditioners to exhaust air, which wastes energy consumption (ventilation volume cannot be controlled), and meanwhile, noise, dust and the like enter the room, for the situation, the chinese patent document with publication number CN200958805 discloses the following technical scheme: referring to fig. 1, the fresh air exchanging device for the air conditioner comprises an air suction pipe 1, a ventilator 2 and an exhaust pipe 3, wherein a pipe orifice of the exhaust pipe 3 is arranged on one side of a volute 5 cavity of a centrifugal fan blade 4 of the air conditioner. The fresh air exchanging device with the structure can realize the fresh air exchanging function for the air conditioner, but the air conditioner is additionally provided with the ventilator 2, so that the air conditioner is complex in structure and the cost is increased.
Disclosure of Invention
The invention aims to provide a split air conditioner indoor unit with low cost and simple structure and capable of changing fresh air.
In order to achieve the purpose, the invention provides the following technical scheme:
an indoor unit of a split air conditioner comprises
The air conditioner comprises a shell, a fan and a fan, wherein an air inlet and an air outlet are formed in the shell;
the multiple groups of inertial flow fan blades are driven by the motor to rotate;
the evaporator is positioned above the inertial flow fan blade;
wherein,
the device also comprises a fresh air exchange fan blade and a fresh air exchange pipe;
the fresh air replacing pipe is positioned on an air outlet channel of the fresh air replacing fan blade and is communicated with the outside.
The fresh air replacing function is realized by newly adding the fresh air replacing fan blade and the fresh air replacing pipe and guiding out the indoor air outdoors, and a large amount of cost is saved without an additional fan and a motor.
The further technical scheme is as follows:
the fresh air replacing pipe is communicated with the outside through a drain pipe.
The drainage pipe and the exhaust pipe are combined into a whole, so that the material is saved, and the air quantity is large.
Drawings
FIG. 1 is a schematic view of a prior art air conditioner;
fig. 2 is a schematic structural view of the indoor unit assembly of the split air conditioner of the present invention;
fig. 3 is a simplified view of the connection relationship between the fresh air changing pipe and the drain pipe of the indoor unit of the split air conditioner.
The invention is further explained with reference to the drawings and the embodiments.
Detailed Description
Example one
Referring to fig. 2, the indoor unit of the split air conditioner includes a casing having an air inlet and an air outlet. And the multiple groups of inertial flow fan blades 2 are driven to rotate by the motor 4. The evaporator 1 is positioned above the inertial flow fan blade 2. The motor 4 is a double-shaft motor, and the inertial flow fan blade 3 is arranged at the other end of the double-shaft motor 4. The fresh air changing pipe 5 is positioned on an air outlet channel of the inertial flow fan blade 3, and the fresh air changing pipe 5 is communicated with the outside through being connected with a drain pipe 6.
Example two
The difference between the present embodiment and the first embodiment is: the motor 4 does not adopt a double-shaft motor, the inertial flow fan blade 3 is fixed at the top end of the inertial flow fan blade 2, the additional inertial flow fan blade 3 is driven to rotate by the power of the inertial flow fan blade 2, and part of air volume is discharged out of the room through the fresh air changing pipe 5 and the water discharging pipe 6, so that the purpose of fresh air changing is achieved.
In addition, as a conventional design scheme in the field, the above-mentioned inertial flow fan blade 3 may also be changed into a centrifugal fan blade.
Of course, the indoor unit of the split air conditioner of the invention can also have other variations. In conclusion, obvious variations on the above-described examples, as well as other modifications, which do not depart from the spirit of the invention, are intended to be included within the scope of the following claims.
