Air conditioner

Abstract

The present invention provides an air conditioner in which a dust box can be correctly installed to prevent troubles coming from incorrect installation of the dust box and that realizes appropriate air conditioning and cleaning operation. The air conditioner has an air conditioning mechanism (X) and a cleaning mechanism (Y) for scraping dust adhered to the surface of a filter (13) and collecting it into a dust box (20. The dust box (20) is removably attached to a containing section (30) on the casing (1) side, and installation detection means (P) for detecting correct installation of the dust box (20) is provided between the dust box (20) and the containing section (30). With such an arrangement, an uninstalled condition and imperfect installed condition of the dust box (20) is detected by the installation detection means (P) and an operator can install the dust box (20) quickly and correctly by confirming detection information. Consequently, cleaning operation and air conditioning operation are reliably limited when the dust box is not installed or imperfectly installed and operational reliability of an air conditioner is enhanced.

Description

technical field [0001] The invention of the present application relates to an air conditioner in which a filter cleaning mechanism is added to an air conditioning mechanism. Background technique [0002] Conventionally, an air conditioner having a cleaning mechanism that automatically cleans a filter is known (see Patent Document 1). The cleaning mechanism of the filter in this air conditioner allows the plate-shaped filter arranged in a reciprocating manner along the inner surface of the air suction port to pass through the inside of the dust box arranged in the moving path of the filter, At the same time, the dust attached to the surface of the filter is scraped off by the brushes arranged on both sides of the cover of the filter in the dust collecting box, thereby realizing the function regeneration of the filter. [0003] In this case, if the filter cleaned by the reciprocating action is not set in the correct position at the end of cleaning, there are cases where, for ...

Problems solved by technology

[0008] On the other hand, if the above-mentioned dust box is not assembled in the correct position for air-conditioning operation, then for the air conditioner with the structure that the blower outlet is provided at the position closest to the dust box, it is necessary to consider the The existence of the dust box causes the air flow of the blown air to change, resulting in condensation or abnormal noise.

In addition, for an air conditioner with a structure in which the dust box is placed near the suction inlet, it is necessary to consider that the presence of the dust box causes the airflow of the intake air to change, thereby increasing the suction resistance or generating abnormal noise.

[0009] However, in the conventional air conditioner, although there is a detection member for the arrangement state of the filter as described above, a member for detecting the installation position of the dust box is not provided. Problems caused by improper assembly state of
