Description

Technical Field

[0001] The present invention relates to the field of air conditioning, and in particular to a filter mechanism and an air conditioner having the same. Background Art

[0002] At present, the filter of the air conditioner usually plays the role of filtering indoor air by preventing dust and other impurities from entering the indoor unit. For the air conditioner, the air outlet needs a higher wind speed in order to send the air flow to a farther position in the room. Therefore, the filter is generally not installed at the air outlet of the air conditioner, otherwise it will increase the wind resistance of the air outlet and affect the wind speed. Therefore, the filter of the air conditioner is usually installed at the air inlet.

[0003] In the prior art, there are cabinet air conditioners that can achieve reversible up and down air outlets. The air conditioner can switch between the upper and lower air outlets through the reversing of the movable volute in the air duct, that is, it can switch between the lower air outlet air intake (upper air outlet state of upper air outlet air outlet) and the upper air outlet air intake (lower air outlet state of lower air outlet air outlet). Therefore, for this type of air conditioner with multiple air outlets that can be used as air inlets and air outlets, it is necessary to set a filter at each air outlet that can be an air inlet, and when the air outlet is switched to an air outlet, the filter also needs to be switched accordingly. The first reason is that it cannot become a wind resistance of the air outlet, thereby affecting the air outlet speed; the second reason is that the impurities on the filter will be blown out during the reverse air outlet, thereby affecting the air quality.

[0004] For the existing air conditioners in the prior art, when the upper air outlet is the air inlet, due to the large space between the heat exchanger and the air outlet, an independent movable filter mechanism can be designed inside the air conditioner to open the filter when the upper air outlet is the air inlet and retract the filter when the upper air outlet is the air outlet, but the cost is high. Moreover, when the lower air outlet is the air inlet, due to the small space, it is not convenient to design an independent movable filter mechanism.

[0005] It can be seen that how to set the filter mechanism and how to switch it synchronously with the switching of the air outlet have become difficult problems for this type of reversible up and down air outlet cabinet. Summary of the invention

At the same time, the filter mechanism is easy to install and convenient to disassemble and clean, which solves the problem in the prior art that the filter mechanism of the air conditioner with reversible air outlet is difficult to switch synchronously with the air outlet.

[0039] Specifically, the baffle 1 and the mounting frame 2 are integrally formed; and / or, the baffle 1 and the filter screen 3 are arranged around a predetermined rotation axis.

[0042] Specifically, the driving component 4 is a motor.

[0043] like Figures 1 to 4 As shown, the filter mechanism further includes: a rotating shaft 5, the rotating shaft 5 is connected to the baffle 1 and / or the mounting frame 2, and the driving component 4 is drivingly connected to the rotating shaft 5 to drive the baffle 1 and the mounting frame 2 to rotate through the rotating shaft 5.
