Front plate decorative board structure of indoor unit of air conditioner

Abstract

A front-panel decorative board of the room unit of air conditioners is made up of at least two layers. One layer is the cover plate made up of plastic units PVC and the other layer is a protection face-plate made of organic glass fixed on the outside surface of the cover plate.

Description

technical field [0001] The invention relates to a decorative plate structure of an air conditioner indoor unit, in particular to a glass mask decorative plate structure of the front panel of an air conditioner indoor unit. Background technique [0002] Air conditioners are currently an indispensable household appliance in people's daily life. The structure of the indoor unit of the air conditioner is a relatively mature technology, which at least includes: an indoor unit base, a cross-flow fan, an evaporator, a dust filter, and a grille. Type face shield, front air inlet plate etc., air inlet grille and face shield are integrally provided with in the earlier air conditioner, and described grille type face shield is usually fixed as a whole with the end of indoor unit base. There are also wall-mounted air conditioner indoor units whose outer shell is generally composed of a front cover and an air intake grille. The top surface of the front cover is provided with an air intake...

Problems solved by technology

However, the indoor unit of this structure has two major defects: accumulation of dust and poor aesthetics

In this utility model, the traditional structure that the front air intake grille of the indoor unit is arranged is arranged by several thin and narrow grilles is changed, and a smooth and closed decorative plate is used instead, and the air is taken in from the upper and lower air inlets of the decorative plate. The decorative board is not easy to collect dust, easy to clean, and avoids the phenomenon of dust being mixed in the air intake. However, the position of the air outlet of the indoor unit is not disclosed in this document, and the decorative board is a one-layer structure, which has poor deformation resistance. The front panel and the front cover The buckle-fitting method between the shells is not very ideal. After all, there are still a few users who remove the front panel for cleaning, and re-installation will inevitably bring certain difficulties. Therefore, the structure needs to be further improved

[0007] As consumers have higher requirements for product quality and appearance, the mask is the "facade" of the indoor unit of the air conditioner and is a very critical part. Usually the existing mask or panel is a one-layer structure, and the existing Wall-mounted indoor units are usually made of light-colored plastic in order to pursue aesthetics. After a long time of use, various external pollutants such as dust and oil fume stick to the mask and penetrate into the interior of the plastic mask, making it difficult for users to clean it. Therefore, some air conditioners have not been used for a long time, and the surface of the air conditioner's mask will look very old, affecting the overall aesthetics of the air conditioner indoor unit, and also destroying the aesthetic effect of home facilities.

[0008] After the air conditioner is used for a period of time, a large amount of dust will be adsorbed on the panel or mask. If it is not cleaned in time, the efficiency will be reduced and the use effect will be affected. If the air conditioner is not cleaned and maintained for a long time, the service life of the machine will be shortened or even damaged. , scrapped; at the same time, it will emit peculiar smell and even blow out dirt with the wind, which is very important for hospital wards and laboratories

[0009] The front panel or mask disclosed in the above-mentioned reference document is unlikely to be disassembled frequently for washing, which is time-consuming and laborious. Moreover, the existing air conditioner has both cooling and heating functions, and the bottom of the front panel is the air outlet. , due to the expansion of each part during heating, the deformation of the matching parts is different due to different materials, inconsistent thickness, uneven heating, etc., and there is mutual pushing between the parts to cause deformation, that is to say, the bottom of the front panel is often affected by hot air , but the upper part of the front panel cannot be affected by the hot air. In this way, the front panel with a thin layer of structure will be mechanically deformed over the years. Even if the manufacturer makes a beautiful and beautiful picture on the front panel, it cannot make up for this. defect
