Abstract

PURPOSE:To provide a filter fitting construction enabling a filter to be smoothly fitted and detached under the condition where a suction grille is fitted to a main body of an air conditioner, by providing a slanted part at an opening part for insertion of the filter of the suction grille. CONSTITUTION:The suction grille 3 is attached with the filter 4 on the back side thereof, and is mounted in the state of being flush with a bottom plate 12 defining the outline, a handle 4-1 of the filter 4 is provided in proximity to the bottom plate 12 in the state of being exposed to the outer surface through an opening part of the grille 3, and the filter 4 can be moved inward and outward by sliding in the direction of arrow 13. Between the handle part 4-1 and the bottom plate 12, a part of the grille 3 is slanted in the same inclination with that of the moving direction of the filter 4, is extended to the lower end part of the bottom plate 12, and is used as a guide for moving the filter 4 inward and outward.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a structure for attaching and detaching a filter to a ceiling-suspended air conditioner.

[Background of the invention]

As shown in Fig. 3, this type of conventional air conditioner has a suction port on the bottom surface, and a suction grill with a removably attached filter is attached to the suction port in a removable manner. The structure is such that it is installed at the front or rear part and opens and closes as shown by the arrow. With this structure, each time the filter is attached or removed, the filter must be removed and the filter removed, which is complicated. In addition, in the case of the rear hinge method, the penetrating nature of the opening allows it to touch the wall surface,
It may damage the wall or cause damage to parts. Even with the front hinge system, there was a problem with the penetrating nature of the device, causing it to hit the operator's face or head. Additionally, a blower was placed above the suction grill, and there was a risk that rotating objects would be exposed when the suction grill was opened. Furthermore, even if the filter can be attached and detached from the suction grill when it is attached to the air conditioner body, as shown in Figure 4,
The suction grill and filter were fixed at a position shifted below the bottom plate, and the filter was inserted and removed.

In this case, the height of the air conditioner becomes large, resulting in high logistics costs.

[Purpose of the invention]

An object of the present invention is to provide a filter mounting structure that allows the filter to be smoothly attached and detached in a ceiling-mounted air conditioner having the suction port on the bottom surface, while the suction grill remains attached to the air conditioner body. It is about providing.

[Summary of the invention]

The present invention is a ceiling-mounted air conditioner having a suction port on the bottom surface, in which a suction grill and a bottom plate are arranged on the same surface of the bottom surface, and a filter attached to the back surface of the suction grill can be easily taken in and out from the opening of the suction grill. This relates to a structure for attaching and detaching the filter that makes it possible to do so.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to FIGS. 1 to 3.

1 is the air conditioner body, 2 is the suction port, 3 is the suction grill, 4 is the filter, 5 is the blower, 6 is the heat exchanger, 7 is the dew pan, 8 is the air outlet, and the air outlet grill 9 is installed. . 10 is a ceiling surface, and 11 is a wall surface. Suction grill 3
is equipped with a filter 4 attached to its back surface so as to be flush with the bottom plate 12 constituting the outer shell, and the flat part 4-1 of the filter 4 is inserted through the opening of the suction grille 3.
It is exposed on the outer surface and installed close to the bottom plate 12, and the filter 4 can be taken in and out by sliding in the direction of the arrow 13. Further, a part of the suction grill 3 is provided between the handle 4-1 of the filter 4 and the bottom plate 12 with the same slope as the direction in which the filter 4 is taken in and taken out.
It is extended to the lowest end of the filter 2 and is provided as an aid when inserting and removing the filter 4.

〔Effect of the invention〕

As described above, according to the present invention, in a ceiling-mounted air conditioner having a suction port on the bottom surface, when the suction grill is attached to the air conditioner body, the filter can be directly inserted through the opening of the suction grill. It becomes possible to put in and take out the filter, and there is no need to open or close the suction grill for the purpose of attaching and detaching the filter, which solves the above-mentioned problems. In addition, by equipping the suction grill and the bottom plate that makes up the outer shell on the same plane,
(In addition, it is possible to make the air conditioner thinner.In addition, by installing a part of the suction grill at an angle in the direction of filter insertion and removal, it is possible to make the air conditioner thinner.) The filter can be put in and taken out smoothly, and the filter can be taken in and out without coming into contact with the bottom plate that makes up the outer shell, which is placed close to the filter, which has the effect of preventing damage to the bottom plate.
