Abstract

PURPOSE:To further reduce the weight and cost of an air conditioner by molding a panel and a bellmouth into one piece with a plastic in terms of an air conditioner where a heat exchanger and a propeller fan are installed inside an equipment housing and a bellmouth is installed to an air outlet installed to a panel opposed to the propeller fan. CONSTITUTION:An outdoor unit for a separation type air conditioner is provided with an equipment casing which comprises a front panel 20, a top panel 21, a rear panel 23, a side panel 24 and a base panel 25. A plastic-made blow off grille 28 is mounted to the front of the front panel 20. In this equipment easing, the front panel 20 and a bellmouth 26 are one piece-molded with a plastic where a propeller fan 27 is installed in such a fashion that it may face an air outlet 29 limited by this bellmouth 26. This construction makes it possible to further reduce the weight of the equipment easing and minimize the number of components and hence manufacture the panels and the bellmouth at a lower cost as well.

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 One example of an outdoor unit of a conventional separation type air conditioner is shown in FIG. The inside of the housing 1 of the outdoor unit is partitioned into a left side and a right side by a partition plate 2, a machine room 3 is formed on the right side, and a heat exchange room 4 is formed on the left side.

A compressor 5 and the like are provided in the machine room 3, and an L-shaped heat exchanger 9 and a propeller fan 1 are provided in the heat exchange room 4.
0, a motor 14 and the like are provided.

The L-shaped heat exchanger 9 is opposed to an air intake 11 formed on the back surface 1a of the housing 1 and an air intake 12 formed on the left side surface 1b. Further, the propeller fan 10 is arranged so as to face an air outlet 13 formed in the front panel 1c of the housing 1, and a bell mouth 15 is fastened to the air outlet 13 by a screw 16.

When the propeller fan 10 is rotationally driven by the motor 14, outside air is introduced from the air intake ports 11 and 12 into the heat exchange chamber 4.
After being sucked into the inside and being heated or cooled by exchanging heat with the refrigerant in the process of passing through the heat exchanger 9, it is urged by the propeller fan 10 and discharged from the outlet 13 to the outside.

[0006]

In the above conventional air conditioner, since the bell mouth 15 is fastened to the front panel 1c by the screw 16, the number of parts is large and the front panel 1c and the bell mouth 15 are troublesome to fasten. However, there is a problem that the cost increases because of the cost.

[0007]

The present invention has been invented in order to solve the above-mentioned problems, and the gist thereof is to arrange a heat exchanger and a propeller fan in a housing and An air conditioner having a bell mouth provided at an outlet formed in a panel facing a propeller fan, wherein the panel and the bell mouth are integrally molded of plastic.

The panel may be composed of a front panel and an outlet grill attached to the front surface of the front panel, and the bell mouth may be integrally formed with the front panel.

The above panel may be composed of a front panel integrally formed with the blowout grill.

[0010]

In the present invention, the panel and the bell mouth are integrally formed of plastic, which contributes to weight reduction and cost reduction.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A first embodiment of the invention is shown in FIG. In FIG. 1, reference numeral 20 is a front panel, 21 is a top panel, 23 is a rear panel, 24 is a side panel, and 25 is a base panel, which constitute the enclosure of the outdoor unit. A blowing grill 28 made of plastic is mounted on the front surface of the front panel 20.

The front panel 20 and the bell mouth 26 are integrally formed of plastic, and the propeller fan 27 is arranged so as to face the air outlet 29 limited by the bell mouth 26. Other configurations are similar to those of the conventional one shown in FIG.

A second embodiment of the invention is shown in FIG. In this second embodiment, the plastic blowing grill 30 also functions as the front panel. And
Bell mouth 26 is integrally formed on the outlet grill 30,
The bell mouth 26 limits the outlet 29.

Extension parts 23a and 24a are formed at the front end of the left side surface of the rear panel 23 and the front end of the side panel 24, respectively.
The rear surface of the blow-out grill 30 abuts on the front surfaces of these extension portions 23a, 24a. The other structure is the first shown in FIG.
The same reference numerals are given to corresponding members.

In the second embodiment, the number of parts is smaller than that of the first embodiment and the number of assembling steps is also reduced, so that the cost can be further reduced.

[0016]

According to the present invention, since the panel and the bell mouth are integrally formed of plastic, it is possible to contribute to weight reduction and it is not necessary to connect the panel and the bell mouth to each other. Therefore, the number of parts can be reduced, the panel and the bell mouth can be manufactured at low cost, and the number of assembling steps can be reduced, so that the cost can be greatly reduced.

If the panel is formed of the front panel integrally formed with the blowout grill, the number of parts can be further reduced, and the cost can be further reduced.
