Abstract

PURPOSE:To contrive to easily cope with model-change and the like, to improve external appearance and to prevent a filter from deforming and the like by a structure wherein a decorative frame and a suction grille are separated from each other and the lateral bars consisting of the suction grille are inclined upwards in the direction of suction. CONSTITUTION:A decorative frame 13 consisting of an external frame and a discharge port 13d (not shown in the figure) and a suction grille 15 consisting of a suction port are separated from each other. The lateral bars 14 of the suction grille 15 are mounted in the manner inclined upwards. Thus, because the decorative frame 13 and the suction grille 15 are separated, the external appearance can easily be changed by changing molding color and decorating method and at the same time model-change can be possible only by changing the mold of the suction grille. In addition, because the lateral bars 14 are inclined upwards, the inclined surface 14a of each bar 14 turns to cover the front, when the titled air conditioner mounted onto wall surface or the like is seen from below, resulting in improving the external appearance of the air conditioner.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a decorative cover for an air conditioner, and particularly to a decorative cover suitable for improving the appearance, improving the design effect, and improving reliability. .

[Background of the invention]

A conventional decorative cover for an air conditioner will be explained with reference to FIGS. 1 and 2. 1 is a base integrally forming a casing 1a. Reference numeral 2 denotes a blower, which is installed together with a heat exchanger 3 in the cabinet l. Reference numeral 4 designates a decorative cover with a plurality of horizontal lattices 5 arranged horizontally on the top and a suction grill 6, and a discharge lower integrally provided at the bottom, from which a wind direction conversion plate 8 can be rotatably taken out. be. Reference numeral 9 is a filter, and is formed by integrally forming a frame 9a made of synthetic resin and a mesh 9b, and is detachably attached to the rear of the suction grille 6.

Reference numerals 10 and 11 are filter guides, and spaces for the filter 9 to be installed are provided between the center and both left and right ends of the suction grille 6 and the rear of the horizontal grid 5 so that the filter 9 can be attached and removed smoothly. It is fixed to the decorative cover 4 with screws or the like. In addition, in recent years, air conditioners have become thinner with smaller depth dimensions, and filters 9
is made thinner, and the filter 9 and heat exchanger 3 are located close to each other, with minimal gaps between them.

In the above-mentioned decorative cover, the suction and closing rills 6 and the discharge lower are integrated to form the decorative cover 4, so if you want to change the appearance due to a model change, etc., you can partially change the mold by using the insert piece exchange method. method, or a method of making a new mold for the entire decorative cover 4, but with the insert piece replacement method, it is not possible to make the insert pieces too large due to the structure of the mold, so there is little change in appearance, but a new mold is made. In this case, it takes a lot of mold cost and production time, making it difficult to respond quickly. In addition, because the horizontal grid 5 is horizontal, the aluminum base color of the heat exchanger 3 is visible not only when the air conditioner is viewed horizontally from the front, but also when viewed from slightly below after it is installed on a wall. It can be seen through the mesh 9b of the filter 9 and spoils the appearance. Here, in order to make the heat exchanger 3 invisible, if the thickness of the horizontal grid 5 is increased to increase the depth dimension, or if the gap between the horizontal grids 5 is narrowed, the ventilation resistance increases ( Furthermore, since the filter guides 10 and 11 are individually molded and fixed to the decorative cover 4 by heat welding or screwing, the number of parts is large (and the assembly productivity is poor).
This results in higher costs. Also, filter guide 10.1
Since the filter 1 only receives the left and right ends of the filter 9, the thinned filter 9 may become loose or deformed near the center. There are drawbacks such as there is a risk that the dew may be transmitted to the filter 9 and drip into the room, and the filter 9 cannot be attached or removed smoothly.

[Purpose of the invention]

An object of the present invention is to provide a decorative cover that can easily adapt to model changes, has a good appearance, prevents deformation of the filter, and has improved reliability.

[Summary of the invention]

The decorative cover is divided into a decorative frame that forms the outer shape and the discharge port, and a suction grill that forms the suction port, and the horizontal lattice of the suction grill is tilted upward, and both left and right ends and approximately the center of the decorative frame are located behind the filter. A decorative design for an air conditioner in which a filter guide is integrated with the decorative frame, and a space for installing a filter is provided between the decorative frame and the suction grill to secure them together.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 3 to 5. Note that the same reference numerals as in the conventional example indicate the same parts. 12 is a decorative cover, and a decorative frame 1 forms the outer shape and the discharge port 13d.
3 and a suction grille 15 forming an inlet, and the horizontal lattice 14 forming the suction grille 15 is inclined upward. On one side of the decorative frame 13, filter guides t3a and 13b are provided at both right and left ends and approximately in the center behind the filter 9, and are integrated with the decorative frame 13 over the entire length of the top and bottom. are connected. Note that there is a space between the decorative frame 13 and the suction grill 15.
A space 16 is provided in which the filter 9 can be attached, and the two are fitted into a structure or screwed together.

Since the decorative frame 13 and the suction grille 15 are separated, it is possible to make various changes to the appearance by changing the molding color and decoration method of each. Making a new mold allows for a major model change, as well as reducing mold costs and shortening the production period, allowing quick response. In addition, since the horizontal lattice 14 of the suction grill 15 is tilted upward, when the air conditioner is installed on a wall or the like, when looking up from slightly below, the front side is covered by the slanted surface 14a of the horizontal lattice 14. Since the heat exchanger 3 located at the rear is not visible, the appearance becomes neat and beautiful. Furthermore, since the filter guides 13a and 13b are provided integrally with the decorative frame 13, the number of parts is reduced, productivity is improved, and costs can be reduced. In addition, since the filter guide 13b is provided approximately at the rear center of the filter 9, the filter 9 is supported at both left and right ends and approximately at the center by the filter kites 13a and 13b, eliminating the risk of the filter 9 deforming. This has the effect of ensuring smooth attachment/detachment operations and improved reliability.

〔Effect of the invention〕

According to the present invention, since the decorative cover 12 is divided into the decorative frame 13 and the suction grille 15, it is possible to easily change the appearance to various extents, and also to reduce mold costs and mold manufacturing time. can. Further, since the horizontal grid 14 of the suction grill 15 is tilted upward, the heat exchanger 3 is not visible when the air conditioner is installed, resulting in a clean and beautiful appearance.

Furthermore, since the filter guides 13a-, 13b are integrally provided with the decorative frame 13 at both left and right ends and approximately in the center of the filter 9, the number of parts is reduced (-Costs can be reduced, and there is no fear that the filter 9 will deform. This has the effect of ensuring smooth attachment/detachment of the parts 9 and improving reliability.
