Since the upper air intake grille can be simply disassembled from the cover of the indoor unit, the evaporator can be directly cleaned with tools such as a vacuum cleaner and a brush.

Description

Housing structure of air conditioner indoor unit

technical field

The invention relates to a housing structure of an air conditioner indoor unit, in particular to an upper air inlet grid structure of the air conditioner indoor unit housing.

Background technique

After the indoor unit of the air conditioner is used for a period of time, a large amount of dust will be adsorbed on the fins and fans of the evaporator. If it is not cleaned in time, it will reduce efficiency, affect cooling and heating effects, increase power consumption, and at the same time emit peculiar smell and even blow out dirt with the wind. Moreover, not cleaning for a long time will also shorten the service life of the machine, and even cause the machine to be damaged or scrapped. Therefore, it is necessary to clean the inside of the evaporator and the indoor unit frequently.

At present, the commonly used indoor unit evaporator cleaning method is to spray with high-pressure water. But as we all know, once the indoor unit of the air conditioner is installed, it will not be disassembled unless it is absolutely necessary. Therefore, the cleaning of the indoor unit can only be carried out on the indoor wall. As a result, the walls around the indoor unit and the ground under the unit will be polluted with sewage. Moreover, washing with water may also cause corrosion of metal parts on the indoor unit, and also have a bad effect on the connection structure and circuits between the parts. In addition, the casing needs to be removed for cleaning with water. Frequent removal of the casing is not only troublesome, but also causes loosening of the overall structure, and vibration noise is generated when the air conditioner is running. Therefore, although washing with water can achieve a better cleaning effect, it will affect the overall performance of the air conditioner and should not be used more. The ideal method is to clean the evaporator, filter screen, air duct and other parts with a vacuum cleaner, brush, etc., so that not only can the filter be kept clean, but also it will not have adverse effects on the structure and components of the air conditioner. But the current indoor unit shell structure is basically a whole, especially the upward air intake grille that directly blocks the evaporator, because it cannot be moved, so the evaporator cannot be directly cleaned with tools such as vacuum cleaners and hair brushes.

Contents of the invention

The object of the present invention is to provide an air conditioner indoor unit shell structure, which can conveniently clean the evaporator directly with tools such as vacuum cleaners and brushes.

In order to achieve the purpose of the above invention, the technical solution adopted by the present invention is as follows: the upper air intake grille is designed as a movable structure, which can be easily disassembled from the indoor unit casing. In this way, when the evaporator needs to be cleaned, as long as the upper air intake grille is removed, the evaporator can be directly cleaned with a vacuum cleaner, a brush and the like.

The detachable upper air inlet grille of the present invention can be connected with the housing of the indoor unit in a clamping manner. The rear edge of the upper air intake grill protrudes backwards with more than two inserts, and there are two buckles at the front of the left and right edges, and the rear side of the air intake grill of the upper air intake grill installed on the indoor unit shell is provided with more than two corresponding to the inserts There are two sockets on the front of both sides of the upper air inlet grille, and the buckles at the front end of the edge of the upper air inlet grille can be inserted into the sockets.

In the above scheme, in addition to buckles and sockets, the rear edge of the upper air inlet grill can also be designed as a piece, and the rear edge of the upper air inlet grill can be designed as a slot, and the rear edge of the upper air inlet grill Insert it in its entirety into this slot.

To realize the detachable structure between the upper air inlet grille and the indoor unit housing of the present invention, other methods can also be adopted, such as setting a buckle or a clamping column on each of the four corners of the upper air inlet grille, and setting a corresponding part of the indoor unit housing. bayonet or card hole, snap the buckle or card post into the bayonet or card hole to install the upper air intake grille on the housing of the indoor unit. Or on the contrary, set the bayonet or card hole on the upper air inlet grille, The corresponding part of the indoor unit shell is provided with a buckle or a clamp post, which can also realize the detachable installation structure of the upper air intake grille and the indoor unit shell. In short, the number of buckles and sockets can be multiple, as long as the upper air intake The grille can be connected to the housing of the indoor unit.

The beneficial effect of using the present invention is that: since the upper air intake grille can be simply disassembled from the indoor unit cover, the evaporator can be conveniently cleaned directly with tools such as vacuum cleaners and brushes, and it is convenient to clean the upper air intake grille itself. Cleaning, avoiding the inconvenience caused by dismantling the housing of the indoor unit as a whole during cleaning, and will not have an adverse effect on the overall structure of the housing of the indoor unit.

Detailed ways

The present invention will be described in detail below with reference to the accompanying drawings.

Example 1

Accompanying drawing 1 is the schematic diagram of the structure of the upward air intake grid of the present invention. Several inserts 11 protrude backward from the rear edge of the upper air intake grill 1, and there are two buckles 12 on the front ends of the left and right edges. Slot 22, in the present embodiment, inserting sheet 11 and slot 22 respectively have three, and inserting sheet 11 on the rear edge of air inlet grid 1 can be inserted in this slot 22; Two sockets 23, the buckle 12 on the front end of the upper air intake grille edge can be inserted into the sockets 23. When installing the upper air intake grille, first insert the inserts 11 on the rear edge of the upper air intake grille 1 into the slots 22 at the rear of the casing, then press down on the front of the upper air intake grille, and insert the two Two buckles 12 snap into the two sockets 23 on the front of the upper air intake grille 21 sides. When dismounting, the buckle 12 is first pulled out from the slot 23, and the upper air inlet grille 1 can be taken off. If you want to clean the air conditioner at this time, you can directly use vacuum cleaners, brushes and other tools to clean the evaporator, which is convenient and will not have any impact on the components and structure of the indoor unit.

Example 2

There is a clip on each of the four corners of the upper air inlet grill, and there are four sockets on the corresponding part of the edge of the upper air inlet grill. When installing the upper air inlet grill, insert the buckles at the four corners of the upper air inlet grill to the edge the corresponding socket.
