DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall-mounted air conditioner.

[0002]

2. Description of the Related Art An example of a conventional wall-mounted air conditioner is shown in FIG. Juan casing 1 and front panel 2
A suction grille 10 is rotatably supported about the shaft 12 at the upper part of the front surface of the main body 19 made of a material. A heat exchanger 3 is disposed inside the main body 19 so as to face the suction grille 10, a once-through fan 4 is disposed downstream of the heat exchanger 3, and an air filter 9 is disposed upstream. Are arranged and detachably attached to the main body 19.

[0003] A drain pan 8 is provided below the heat exchanger 3, and an outlet 5 formed at a lower portion of the front panel 2.
Are provided with horizontal flaps 6a and 6b and a louver 7.

During operation of the air conditioner, the once-through fan 4 rotates, and a refrigerant from an outdoor unit (not shown) circulates in the heat exchanger 3.

[0005] Then, the indoor air flows from the suction grill 10 to the main body.
When sucked into the air filter 19 and flows through the air filter 9, dust contained therein is removed. Then, in the process of flowing through the heat exchanger 3, the refrigerant is cooled or heated by exchanging heat with the refrigerant, and then sucked into the once-through fan 4 to be urged. It is regulated and blown out from the outlet 5 into the room.

[0006]

This type of wall-mounted air conditioner is usually installed on a wall in a room through an installation plate 11 at a height higher than the height of a person. Then, when the air filter 9 becomes dirty or when a predetermined operation time has elapsed, it is necessary to take out the air filter 9 and clean it.

However, in the above-mentioned conventional wall-mounted air conditioner, the upper part of the suction grille 10 is rotatably supported on the upper part of the front surface of the main body 19 so as to be rotatable around the horizontal shaft 12, so that the air filter 9 is cleaned. In this case, the user must ride on a chair or stepladder, open the suction grill 10 as shown in FIG. 2, and attach / detach the air filter 9 while holding the suction grill 10 by hand. Was not only dangerous, but also dangerous.

In addition, since the suction grille 10 is attached to the main body 19 by a complicated mechanism, it is difficult for a general user to attach and detach the suction grille 10, and therefore, the suction grille 10 is detached from the main body 19 for cleaning. I couldn't do that.

DISCLOSURE OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the gist of the present invention is to suck into the main body through a suction grill provided on the front surface of the main body. the room air is the air filter, heat exchanger, in the wall-mounted type air conditioner issued can blow through the fan in this order, the upper end of the pair of rail grooves extending in the vertical direction provided on left and right sides of the body horizontal With refraction
At the bottom of the suction grill.
Fitted slidably in the rail groove on the left and right sides, the wall hanging type air conditioner which is characterized in that a detachable rail guide than the open bottom end of the rail groove.

Another feature is that the air filter is held on the back surface of the suction grill.

[0011]

According to the present invention, Hikioroshi the suction grille downwardly, the rail guide is slid along the rail grooves remove the suction grille by disengaging from the open bottom end of the body. When the suction grill is attached to the main unit by the reverse operation , the suction grill is
It becomes rotatable around the horizontal bending portion .

When the air filter is held on the back surface of the suction grill, the air filter is removed from the back surface after removing the suction grill from the main body.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIG. Rail grooves 22 extending in the vertical direction are provided on both left and right sides of the front surface of the main body 19, the upper end 23 thereof is bent horizontally, and the lower end 24 is open. On the other hand, rail guides 21 which are slidably fitted in the rail grooves 22 and are detachable from the lower ends thereof are provided on the left and right sides on the upper rear surface of the suction grille 20.

An air filter 25 is detachably attached to the back of the suction grill 20. Reference numeral 13 denotes an air circulation hole provided on the front surface of the front panel 2.
The other configuration is the same as that of the conventional one shown in FIG. 3, and the corresponding members are denoted by the same reference numerals and description thereof will be omitted.

When cleaning the air filter 25, the user holds the suction grille 20 and pulls it down.
Then, since the rail guide 21 exits from the open lower end 24 of the rail groove 22 and slides in the rail groove 22, the suction grille
20 can be easily removed from the main body 19. In this state, the air filter 25 is removed from the back surface of the suction grille 20 and is cleaned. Then, if necessary, the suction grill 20 is washed.

When the cleaning and cleaning of the air filter 25 and / or the suction grille 20 is completed, the air filter 25 and the suction grille 20 are attached to the main body 19 by the reverse operation.
In this state, the suction grill 20 is horizontally bent at the upper end of the rail groove 22.
Locked to part 23 becomes freely opening and closing rotates about a horizontal axis.

[0017]

[0018]

According to the present invention, both the left and right sides of the main body are provided.
The upper ends of a pair of rail grooves extending vertically
And the lower end is opened, and the suction grill
Since the rail guides are provided on the left and right sides of the upper part of the back of the back, the suction grill is pulled down, the rail guide is slid along the rail groove, and if it is detached from its open lower end,
Even if you do not ride on a chair or stepladder,
Since it can be easily and safely removed , it can be easily cleaned.

Further, if holding the air filter on the back surface of the suction grille, it can be cleaned in air filter easily.
