Filter used for air conditioning unit

Abstract

The invention discloses a filter used for an air conditioning unit. A limiting frame and a fixed frame are spliced, and a positioning bar on the limiting frame is inserted into the fixed frame. A limiting block connected to an inserting rod enters a limiting groove of the fixed frame. Fixation is kept under the action of a slippage rod, and the position relation between the limiting frame and the fixed frame can be stably limited. Pressing parts on filter bags are tightly pressed on pressing bars and placing bars, and an extending part is tightly pressed between the limiting frame and the fixed frame. By controlling the slippage rod, the inserting rod can be moved, the limiting block can be disengaged from the limiting groove, and thus the limiting frame can be separated from the fixed frame. According to the scheme, a novel mechanical structure is adopted. The filter used for the air conditioning unit has the following advantages and effects that the filter bags can be stably installed through fixation between the fixed frame and the limiting frame, the filtering effect can be stably achieved, the limiting frame and the fixed frame can be dismounted by controlling the slippage rod, the filter bags can be replaced conveniently, and operation is convenient and fast.

Description

technical field [0001] The invention relates to an air conditioner, in particular to a filter for an air conditioner unit. Background technique [0002] The combined air conditioning unit is a kind of air handling equipment assembled from various air handling functional sections. Suitable for air conditioning systems with resistance greater than 100Pa. The air handling function section of the unit includes: air mixing, flow equalization, filtration, cooling, primary and secondary heating, dehumidification, humidification, blower fan, return fan, water spray, noise reduction, heat recovery and other units. In the process of air circulation, the air needs to be filtered to remove impurities in the air and protect the hygiene of the indoor environment. [0003] Notification number is CN205505355U Chinese patent a kind of air conditioner air filter, comprises outer frame, inner frame bar and composite filter bag, and the bag mouth of composite filter bag is fixed on the outer ...

AI Technical Summary

Problems solved by technology

[0004] However, the disassembly and assembly of the outer frame in the above invention is relatively complicated. When the filter bag needs to be replaced after a long period of use, it is often discarded together with the outer frame strip and the inner frame strip, resulting in a large amount of waste of resources.
