PURPOSE:To set an opening optionally so that it is not directed to a barrier and solve the limitation of the setting position of compressor by constituting each of intake and exhaust ducts provided on a sound proofing wall for receiving a compressor and its driving source in such a manner that they can be opened in optional directions, respectively. CONSTITUTION:An intake hold 5 and an exhaust hole 6 are formed on the rear panel 4a of a sound proofing box 4 receiving a compressor and its driving source therein. Each hole 5, 6 is covered with a box cover 7, and an intake duct 8 and an exhaust duct 9 are formed on the respective circumference. In this case, a number of intake and exhaust opening parts 8a-8c, 9a-9c are formed on the duct 8, 9 parts in the cover 7, respectively. Each plate clog panel 10, 12 and each net inlet and exhaust panel 11, 13 are selectively attached and removed to the opening parts 8a-8c, 9a-9c, respectively. Hence, the intake and exhaust panels are mounted on only the opening parts positioned in the directions having no barrier, and the limitation of setting position is solved.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a so-called package-type compressor in which a compressor main body, a driving source, etc. are housed in a soundproof box to prevent noise diffusion.

(Prior art) In this package type compressor, the temperature inside the soundproof box rises due to heat generated from a drive source such as a motor and heat generated from the fluid compressed by the compressor body.
This may lead to a decrease in compression efficiency and durability of each member.

Therefore, conventional compressors are shown in FIGS. 4(a) and 4(b).

As shown in (C) and (d), in order to perform cooling while preventing the spread of noise as much as possible, a drive source (not shown) installed in the soundproof box l is used to utilize a fan (not shown). Rotate the rear panel of the soundproof box l! Outside air is introduced from an opening 2a provided on the side (to the right in FIG. 4(d)) of the intake duct 2 attached to the air intake duct 2, which cools the compressor body (not shown) and the drive source. Cooling structure in which warmed air used for cooling is discharged from an opening 3a provided on the side (leftward of the fourth peak (d)) of the exhaust duct 3 attached to the rear panel la of the soundproof box l. Some had mechanisms. (A compressor having this type of cooling mechanism is disclosed in Japanese Utility Model Publication No. 52-47767).

(Issue Ii to be solved by the invention) However, in the cooling mechanism provided in the conventional compressor, the openings 2 of the intake duct 2S and the exhaust duct 3
Since a and 3a face in a certain direction, when installing in a corner of a room, the openings 2a and 3a may face the wall, so it is sufficient if the R openings 2a and 3a are close to the wall. Since it is not possible to take in or exhaust a sufficient amount of air from each duct 2.3, cooling cannot be performed efficiently.
In that case, the openings 2a and 3a of the duct 2.3 must be separated from the wall by a certain value or more.In other words, the installation position of the compressor is restricted by obstacles in the direction of the opening of the duct, and the openings 2a and 3a of the duct 2. There were problems such as the need for a range.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a compressor that is not subject to restrictions on installation position.

(Means for Solving the Problems) The compressor of the present invention includes a soundproof box that houses the compressor main body and a drive source, and an air intake duct for introducing outside air into the soundproof box, and an air intake duct for introducing outside air into the soundproof box. In the compressor provided with an exhaust duct for discharging to the outside, at least one of the intake duct and the exhaust duct can be opened in any direction.

(Function) According to the above configuration, depending on the installation position of the compressor, the opening directions of the intake duct and exhaust duct can be arbitrarily set so as not to face obstacles such as walls, and the compressor main body The introduction of outside air into the compressor and the exhaust of air from within the compressor body can be carried out smoothly.

(Example) Next, embodiments of the present invention will be described based on the drawings.

FIG. 1 is a perspective view of the first embodiment. The rear panel 4a of the soundproof box 4 houses the compressor main body (not shown) and a drive source such as a motor for driving the compressor main body. It has an air intake hole 5 and an exhaust hole 6 that communicate with the outside, and these holes 5.6 are covered with a box-shaped cover 7 whose inside is partitioned by a partition plate 7a. A portion (upper side) that covers the intake hole 5 constitutes an intake duct 8, and a portion (lower side) that covers the exhaust hole 6 constitutes an exhaust duct 9. A fan (not shown) connected to a drive source is arranged inside the compressor facing the intake hole 5, and as the fan rotates, outside air is sucked into the soundproof box 4 from the intake hole 5. Since the inside of the compressor 4 is sealed, the introduced air cools the compressor main body and the drive source and is then exhausted to the outside from the exhaust hole 6.

Openings 8a, 8b, and 8c are formed at three locations on the side surface of the portion of the cover 7 that constitutes the intake duct 8, and
Openings 9a, 9b, and 9c are also formed at three locations on the side surface of the portion of the cover 7 that constitutes the exhaust duct 9. A plate-like closing panel lO or a mesh-like intake panel ti can be attached to and removed from each opening 8a, 8b, 8c on the intake duct 8 side, and each opening 9a, 9b on the exhaust duct 9 side
, 9c, a plate-like closing panel 12 or a mesh-like exhaust panel 13 is also removably attached. Note that if the sizes of the openings +1a, 8b, 8c of the intake duct 8 and the openings 9a, 9b, 9c of the exhaust duct 9 are made the same, the closing panels 10 and 12, the intake panel 11, and the exhaust panel 13 can be used in common. It can also be used as

The operation related to the above configuration will be explained.

When arranging the compressor, the openings 8a, 8 of the intake duct 8
b, 8 (and openings 9a, 9b of exhaust duct 9).

The intake panel 11 and the exhaust panel 13 are respectively attached to the openings (8a and 9c in the figure) facing in the direction where there are no obstacles such as walls among the openings 9c, and the other openings 8b, 8c, 9
By attaching closing panels 10.12 to a and 9b, an intake duct 8 and an exhaust duct 9 which are open in a direction free of obstacles are constructed. In order to prevent the warm air exhausted from the exhaust duct 8 from being sucked in again, it is preferable that the openings of the intake duct 8 and the exhaust duct 9 are set so as not to be oriented in the same direction.

In this way, the opening of the intake duct 8 and the opening of the exhaust duct 9 can be oriented in a direction free of obstacles, so that a sufficient amount of air can be drawn from the opening of each duct 8.9 regardless of the installation position of the compressor. Supply and discharge can be carried out, and cooling can be carried out efficiently.

Next, a second embodiment will be explained based on FIG. 2.

In this embodiment, an air intake duct 15 is constructed by covering the air intake hole 5 formed in the rear panel b of the soundproof box 4 with a box-shaped cover 14 having an opening 14a formed on the side surface.
An exhaust duct 17 is constructed by covering the exhaust hole 6 with a box-shaped cover 16 having an opening 16a formed on one side, and each cover 14.16 is fixed to the rear panel 4a with screws I8. It has become. Note that a net may also be attached to the openings 14a and 16a to prevent dirt from entering.

According to this configuration, each cover 14, 15 is attached to the soundproof box 4 with the openings 14a, 16a facing in a direction free from obstacles such as walls.
By fixing it to the rear panel 4a with screws 18,
Regardless of the installation position of the compressor, the intake duct 15 and the exhaust duct 17 can be opened in a direction free of obstacles. In this case as well, it is preferable that the openings of the intake duct 15 and the exhaust duct 17 are set so as not to be oriented in the same direction, as in the first embodiment.

Next, a third embodiment will be described based on FIG. 3.

In this embodiment, an intake hole (not shown) formed in the rear panel 4a of the soundproof box 4 is covered with a bottomed cylindrical cover 19 having an opening 19a formed in a certain range on the outer periphery. The intake duct 22 is attached to an exhaust hole (not shown) so as to cover a bottomed cylindrical cover 21 having an opening 21a formed in a certain range on its outer periphery. Each cover consists of 19.21
is rotatably supported by the rear panel 4a.

According to this configuration, by rotating each cover 19, 21 so that the openings 19a, 21a face in a direction where there are no obstacles such as walls, each duct 20, 22 is protected from obstacles regardless of the installation position of the compressor. It can be opened in the opposite direction. Further, in this embodiment, even after the compressor is installed, each duct 20.22 can be opened in an optimal direction by rotating the force bar 19.21.

(Effects of the Invention) As described above in detail, the present invention provides for directing at least one of the intake duct for introducing outside air into the soundproof box of the compressor and the exhaust duct for discharging air from inside the soundproof box in any direction. Since the ducts can be opened, the openings of each duct can be set so as not to face obstacles such as walls. As a result, sufficient cooling can be achieved, so the installation position of the compressor is not restricted and the installation range does not become wide.
