DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner for conditioning indoor air, and more particularly, to oil smoke.
The present invention relates to an air conditioner suitable for being installed in a restaurant or a factory where a lot of air is generated.

[0002]

2. Description of the Related Art Conventionally, in order to harmonize indoor air, an air purifier or an air conditioner which introduces indoor air mixed with dust, cigarette smoke, etc. into the apparatus and circulates clean air into the room. Etc. are provided. As shown in a sectional view of FIG. 3, an air purifying device, which is a type of this air conditioner, suspends a casing 21 on a ceiling surface 30 and removes indoor air from a suction grill 22 on the lower surface side of the casing 21. 21, the particulate components in the air are removed by an electric dust collection unit 23, a filter, or the like, and clean air is blown through a blower 25 through a blower 24.
Ceiling-hanging type, which is sent from a room to a room, is generally used.

[0003]

By the way, in the above-mentioned ceiling-suspended type air conditioner, the oil particles contained in the air introduced into the casing 21 are subjected to a suction grill while the oil particles are used for a long time. There is a problem in that it adheres to the surface of the louver 22a of 22 and deteriorates the appearance. In particular, when installed in a place where a lot of oil smoke is generated, such as a restaurant or a factory such as a barbecue shop, an eel shop, a Chinese restaurant, etc., oil particles adhere to the louver 22a intensely, and the oil particles are icicle-like in the louver 22a chamber. In addition to drastically lowering the appearance from the inner end portion, there is a problem that the floor, furniture, appliances, etc., which are located at the lower part of the air conditioner, eventually fall as oil droplets and become dirty.

Accordingly, the present invention solves the above-mentioned technical problems, and prevents an oil droplet from dropping from a suction grill to contaminate floors, furniture, appliances, etc., and has an excellent appearance. It is intended to provide.

[0005]

An air conditioner according to the present invention is provided with a suction grill provided with a plurality of louvers at an air inlet of a casing, and a ceiling for sending air introduced into the casing to a blow grill through a blower. In the suspension type air conditioner, the suction grill is provided on a side surface of a casing, and an upper surface of each louver of the suction grill is inclined downward from the indoor side toward the inside of the casing, and a lower portion of the suction grill is provided. An oil receiving portion for receiving oil flowing down along the louver is provided.

[0006]

According to the above construction, since the upper surface of the louver of the suction grill is inclined downward from the room toward the casing, the oil contained in the air is guided by the downward gradient of the louver and is formed by the suction grill. It gathers in the oil receiving part provided in the lower part. In addition, since the suction grill is provided on the side surface of the casing, when the air conditioner is looked up from the room, the suction grill dirty with oil is difficult to see, which is preferable in appearance.

[0007]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a cross-sectional view showing an air purifier as one embodiment of a ceiling-suspended air conditioner of the present invention. In this figure, this air purifying device is provided on a casing 1 suspended from a ceiling 10, a suction grill 2 removably provided at an air suction port on a side surface of the casing 1, and a lower portion of the suction grill 2. Oil receiving portion 6, a blow-out grill 5 provided on a side surface of the casing 1 opposite to the suction grill 2, and air provided in an air flow passage formed between the suction grill 2 and the blow-off grill 5 in the casing 1. It is provided with an electric dust collection unit 3 for removing particulate components therein and a blower 4 for sending clean air into a room.

In this air purifying apparatus, the suction grill 2 has a plurality of louvers 2a arranged in multiple stages, as shown in FIG. 2, and the upper surface of each louver 2a has a casing 1 from the indoor side. Has a downward slope toward the inside of the lower louver 2a.
An oil receiving portion 6 for receiving oil flowing down along the louver 2a is integrally formed.

In the case of using the air purifying device having such a configuration, oil particles contained in the air are guided to the upper surface 2b of the louver 2a and reach the inner end 2c of the casing 1 of the suction grill 2, and the oil particles are collected. Oil drops fall into the oil receiving portion 6 below the lower louver 2a. Thus, the oil in the air is collected in the oil receiving section 6. Therefore, the user only has to oil the oil when the oil has accumulated in the oil receiving portion 6 to a certain extent, and the oil particles fall off as oil droplets outside the air purifying device, thereby contaminating the floor, the furniture, appliances and the like. There is no fear. Further, when the air conditioner is viewed from the room, the suction grill 2 with the oil is difficult to see because the suction grill 2 is provided on the side surface of the casing 1, which is preferable in appearance.

In the above embodiment, the louvers 2a of the suction grill 2 are tapered so that oil particles in the air are guided to the oil receiving portion 6. For example, the upper and lower surfaces are parallel. The louvers 2a may be arranged so as to be inclined so as to descend toward the inside of the casing 1. In the above embodiment, the suction grill 2 and the oil receiving portion 6 are manufactured by integral molding. However, the suction grill 2 and the oil receiving portion 6 are manufactured separately, and the casing of the suction grill 2 is manufactured. The oil receiving portion 6 may be provided at the bottom on one side. Further, in the above embodiment, an example of the air cleaning device has been described. However, the present invention may be applied to an intake grill of an air conditioner or another air conditioner.

[0011]

As described above, according to the air conditioner of the present invention, the oil particles contained in the air are guided to the louvers of the suction grill and collected in the oil receiving portion. It is possible to prevent the floor, furniture, utensils and the like from dropping and contaminating the floor. Moreover, when the air conditioner is looked up from the room, it is difficult to see the suction grill dirty with oil, so that the appearance is excellent.
