Problems solved by technology

If such a filter is installed as a pre-filter for an air conditioner, there will be a problem that the refrigeration cycle capacity of the air conditioner will decrease.
[0011] On the other hand, the pre-filter for the indoor unit of the air conditioner is installed in a position where it is exposed when the front panel of the indoor unit is opened. Although metal is splashed on the net, the metallic luster does not come out and the design is not good. The problem

Embodiment Construction

[0032] Hereinafter, an embodiment of the present invention will be described using the drawings. First, an air conditioner to which the prefilter of this embodiment is applied will be described with reference to FIG. 1 . Fig. 1 is a longitudinal sectional view of an indoor unit of an air conditioner to which a prefilter according to this embodiment is applied.

[0033] The indoor unit 10 of the air conditioner is composed of a casing 1 , a heat exchanger 5 , and a ventilation fan 6 as main components.

[0034] The casing 1 is composed of a decorative frame 2 and a bottom frame 3, and has a suction port 1a on the upper part and an air outlet 1b on the lower part. Ventilation fan 6 (DC fan) is arranged in the center of housing 1, and the flow of indoor air is shown by hollow arrows. The indoor air is sucked in from air inlet 1a and blown out from air outlet 1b. The heat exchanger 5 is disposed on the suction side of the ventilation fan 6 so as to exchange heat with indoor air....

Abstract

Provided is a pre-filter capable of easily peeling off dust or contaminant attached to it, preventing intrusion of contaminant, having a high quality feeling by metallic film and antibacterial action, and preventing damage at the time of attachment and detachment. In this pre-filter comprising resin fiber mesh such as PP, PET and ABS collecting dust in indoor air, and a resin frame supporting the resin fiber mesh, the surfaces of the resin fiber mesh are subjected to metallic film treatment or sputtering of stainless steel.

Description

technical field [0001] The present invention relates to an air conditioner provided with a dust collection pre-filter for collecting dust contained in the air when absorbing the air. Background technique [0002] The indoor unit of the air conditioner is provided with an indoor heat exchanger in order to condition indoor air. The indoor heat exchanger is formed of a plurality of fins made of aluminum alloy and copper refrigerant tubes inserted into holes formed in the fins. The intervals between the fins and the fins are minute intervals, and the indoor air flows therebetween to exchange heat between the refrigerant and the air. A DC fan for blowing air is provided downstream of the air flow of the indoor heat exchanger. When the DC fan rotates, the indoor air is blown out from the air inlet provided on the indoor unit through the heat exchanger, and the DC fan is blown out from the air outlet. [0003] However, if indoor air containing dust is directly introduced into th...
