Abstract

PURPOSE:To enable noises caused by an outdoor device for an air conditioner to be reduced without increasing the cost of the outdoor device by providing a noise-proof cover serving also as a partition wall between a heat-exchanging chamber and a machine chamber in the outdoor device. CONSTITUTION:A noise-proof cover 19 having an opening on its lower surface is entirely formed into a hanging bell shape and, throughout the circumference of the opening, a fixing flange part 20 is formed integrally with the noise-proof cover. The flange part 20 is tightened and fixed to a bottom plate 4 of an outdoor device with screws or the like in such a manner that a compressor 14 and pipelines are covered with the noise-proof cover. The pipelines and wirings which are arranged to the compressor 14 and the like are withdrawn therefrom to the exterior of the noise-proof cover 19 through small bores provided on the constituting face thereof, and the noise-proof cover 19 has a structure in which the gaps between the small bores and the pipelines and wirings withdrawn are sealed with a rubber push 21. A sound absorbing material is bonded to the bottom surface 26, the side surface 27 and the top surface 28 of the inside of the noise-proof cover 19 which contacts with a heat exchanger 10 through a sealing material 22 to prevent inlet air from being bypassed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the configuration of an outdoor unit of a nine-separate air conditioner, and firstly, to measures against noise in a machine room whose main sound source is a compressor.

[Conventional technology]

Due to the diversification of usage patterns associated with the spread of air conditioners, there is a strong desire to reduce operating noise. In particular, from the perspective of neighborhood noise, reducing the noise of outdoor units of separate air conditioners is an important issue.

6 to 1 are a perspective view and a plan sectional view showing an outdoor unit of a conventional separate air conditioner disclosed in, for example, Japanese Patent Laid-Open No. 58-54810.

In the figure, (1) is the outdoor unit main body, and the outer shell is composed of a front plate (2), a back plate (3), a bottom plate (4), and a top plate (5).

The back plate (3) has a U-shape with both sides integrally formed. A suction port (6) is completely opened on the back and left side of the back plate (3). (7) is a partition plate that divides the inside of the main body (1) into a machine room (8) and a heat exchange room (9). and is installed in contact with the heat exchanger aI. Heat exchanger <11
The entire 6-1 is formed into a 5-shape, and the suction port (6)K
They are placed opposite each other in the heat exchange chamber (9). fan I
is pivotally supported by the motor (13) and is attached by a support tool to face the air outlet a opened in the front plate (2).

In the machine room (8), the compressor Q4 is elastically attached to the bottom plate (4) with anti-vibration rubber, etc., and the electrical equipment α is installed above it.
3 is placed with the mounting plate all 4C*J) attached. Soundproof material is wrapped around the compressor α turret.

In addition, a soundproof board made of overlapping sound insulating material and sound absorbing material is installed at the bottom.

Next, the operation will be explained.

When the power is turned on, motor a and compressor I start. Outdoor air is introduced into the outdoor unit main body (1) from the suction port (6) through the heat exchanger section by rotation of 77 degrees aυ, and is blown out of the main body again from the blow-off port (I3). During operation, the refrigerant circuit operates, and heat is exchanged by ventilation to the heat exchanger a.

The partition plate (7) fulfills two functions: forming an air path for efficient air blowing and insulating noise from the compressor a4 from the machine room (8).

[Problems to be Solved by the Invention] Since the conventional outdoor unit is configured as described above, the sound insulation performance of the contact surfaces between the peripheral part of the partition plate and the external surface such as the front plate, bottom plate, and top plate is taken into account. Seal properties cannot be obtained. Therefore, no effective soundproofing effect can be expected, and additional means are required to reduce noise, resulting in a significant increase in cost.

This invention was made to solve the above-mentioned problems, and aims to provide an outdoor unit that can significantly reduce noise without increasing costs.

[Means to solve the problem]

An outdoor unit of an air conditioner according to the present invention is:

an outdoor unit main body; a heat exchange chamber provided in the main body and having a heat exchanger and a blower; a machine room provided in the main body and having a compressor; and a machine room provided in the compressor.

A soundproof cover is provided that also serves as a partition wall between the heat exchange room and the machine room.

[Effect]

In this invention, the soundproof cover insulates the compressor from sound, and the soundproof cover also serves as a partition wall between the heat exchange room and the machine room.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In Figs. 1 to 5, (1) is the outdoor unit main body, and the outer shell is composed of a front plate (2), a back plate (3), a bottom plate (4), and a top plate (5). The front plate (2) has a U-shape with both sides integrally formed. A suction port (6) is opened on the entire surface of the back plate (3) and on the left side of the front plate (2). On the right side of the main body (1), the compressor 04 is elastically attached to the bottom plate (4) with anti-vibration rubber, etc., and the peripheral piping 99 is connected to the compressor A4 etc. by welding or other methods, and the refrigerant circuit is connected. is formed. The heat exchanger 01 is formed into a 5-shape as a whole and is placed opposite the suction port (6). Fan aυ is motor &
