Abstract

PURPOSE: To enable removing of a cassette type diffuser from the main body to wash when it is fouled by mounting the cassette type diffuser on the diffusion of the main body free to load on or unload from the main body. CONSTITUTION: A cassette type diffuser 30 is mounted on the diffuser 5 of the main body free to load on or unload from the main body 19. During the operation of air conditioning equipment, air in a room passes trough an air duct 13 and is blown into a room at the diffuser 5 via an internal path of the cassette type diffuser 30, namely, a passage limited by internal surfaces 30c thereof. With an increase in accumulated operation of the air conditioning equipment, when the internal surfaces 3c of the cassette type diffuser 30 are fouled, the cassette type diffuser 30 can be pulled out of the diffuser 5 of the main body 19 to clean up by washing or the like.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an 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 room air suction port 11 is provided in the upper part of the front surface of the main body 19 consisting of, and an air outlet 5 is provided in the lower part. A suction grill 10 is rotatably supported by the suction port 11 so as to be rotatable around a shaft 12.

An air passage 13 is formed inside the main body 19 to connect the suction port 11 and the air outlet 5, and an air filter 9 is arranged in the air passage 13 so as to face the suction grill 10. A heat exchanger 3 is arranged downstream of the air filter 9, and a flow-through fan 4 is arranged downstream of the heat exchanger 3.

A drain pan 8 is arranged below the heat exchanger 3, and horizontal flaps 6a, 6b and a louver 7 are provided at the air outlet 5.
Is provided.

During operation of the air conditioner, the once-through fan 4 rotates, and the refrigerant from the outdoor unit (not shown) circulates in the heat exchanger 3. Then, the indoor air is sucked into the ventilation passage 13 through the suction grille 10, and when passing through the air filter 9, the dust contained therein is removed. Then, in the process of passing through the heat exchanger 3, it is cooled or heated by exchanging heat with the refrigerant, then sucked into the flow-through fan 4 and urged, and then blown out by the louver 7 and the horizontal flaps 6a and 6b. It is regulated and blown out into the room from the outlet 5.

[0006]

In recent years, it has been proposed to remove the suction grille 10 from the main body 19 and wash it with water when the suction grille 10 becomes dirty. However, there is a problem in that the air outlet 5 cannot be washed with water because it cannot be removed from the main body 19 despite being dirty.

[0007]

SUMMARY OF THE INVENTION The present invention has been invented to solve the above-mentioned problems, and its gist is to provide a main body with an inlet and an outlet for indoor air, In the air conditioner in which the room air sucked into the ventilation passage in the main body through the air filter, the heat exchanger, and the fan is blown out into the room from the blowout opening, a cassette-type blowout opening is provided at the blowout opening of the main body. The air conditioner is detachably attached to the main body.

Another feature is that slits for inserting and fixing the cassette type air outlet into the main body are provided on both side surfaces of the cassette type air outlet.

Still another feature is that a recess is provided on the inner surface of the air outlet of the main body, and the inner surface of the air outlet is flush with the inner surface of the ventilation passage by fitting the cassette air outlet into the recess. There is something I did.

[0010]

In the present invention, when the cassette type air outlet becomes dirty, it is removed from the main body and washed with water.

By fitting the cassette type air outlet into the recess, the inner surface of the air outlet can be flush with the inner surface of the ventilation passage, and the slit can be inserted and fixed in the main body.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIG. 1, where (A) is a longitudinal sectional view and (B) is a perspective view of a cassette type outlet. FIG.
As shown in (A), a bottomless box-shaped cassette type outlet 30 shown in FIG. 1 (B) is detachably attached to the outlet 5 of the main body 19.

On both side surfaces 30A of the cassette type outlet 30, slits 31 for inserting and fixing in the main body 19 are respectively formed at the rear edges.
It is provided by cutting a predetermined length from 30B. On the other hand, a recess 32 is formed on the inner surface of the air outlet 5 of the main body 10.

The cassette type outlet 30 is connected to the main body 19 from the outlet 5.
After being inserted into the recessed portion 32 and fitted into the recess 32, the slit 31 is used to fix the main body 19. Then, the inner surface of the cassette-type outlet 30
30C is flush with the inner surface 13a of the ventilation passage 13. Other configurations are the same as those of the conventional one shown in FIG. 2, and corresponding members are denoted by the same reference numerals and the description thereof is omitted.

During operation of the air conditioner, however, the room air flows through the ventilation passage 13 and the internal passage of the cassette type air outlet 30,
That is, the air is blown out from the air outlet 5 into the room through the flow passage limited by each inner surface 30C.

When the inner surface 30C of the cassette-type outlet 30 is contaminated due to an increase in cumulative operating time of the air conditioner, the cassette-type outlet 30 is pulled out from the outlet 5 of the main body 19 and washed by washing with water or the like. it can.

[0017]

In the present invention, since the cassette type outlet is detachably attached to the main body at the outlet,
When the cassette outlet is dirty, it can be removed from the main body and washed with water.

If slits for inserting and fixing the cassette type air outlet into the main body are provided on both sides of the cassette type air outlet, the cassette type air outlet can be fixed to the main body using the slits and the cassette type air outlet can be used. Can be smoothly pulled out or inserted from the main body.

If a recess is provided on the inner surface of the air outlet of the main body and the inner surface of the air outlet is flush with the inner surface of the air passage by fitting the cassette air outlet to the inner surface of the air passage, the air flowing through the air passage is the cassette. The air is blown out smoothly from the air outlet without being obstructed by the air outlet.
