Abstract

PURPOSE:To provide a blow-off and suction unit while suppressing the rotational speed of blowers to a low value with a low noise by dividing a case into a upper chamber and a lower chamber and installing blowers laterally in respective chambers, setting the diameter of a fan to a maximum diameter capable of being put into the case, and increasing the capability of the unit by using two blowers. CONSTITUTION:A square-shaped case 11 has a room side opening part 12 communicating with a room and a duct side opening part 13 communicating with an air conditioning apparatus, and a partition plate 14 is disposed laterally inside the case 11 to divide the same into an upper chamber and a lower chamber. Within these chambers blowers 18a and 18b are mounted on the partition plate 14, the blow-off directions of these blowers are opposed to each other. A motor 25 for rotating both blowers 18a and 18b is supported by the partition plate 14. Accordingly, the diameter of the fans 20a and 20b can be set to the maximum value at which the fans 20a and 20b can be accommodated into the unit case 11, and the capability of the unit can be increased by using two blowers 18a and 18b, thus a blow-off and suction unit of a low noise is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a blow-off/suction unit for an air conditioner in one room.

(Prior Art) As an air conditioner for a building, an air conditioner has been developed that has one air conditioner for heating and cooling, and cools and heats a plurality of rooms from the air conditioner through a duct.

For example, as shown in FIG.
Through a duct 2 having a blow-off passage 2a and a return passage 2b, the air-conditioned air is connected to a blow-off suction unit 10.1o whose one side is open, into each of the rooms 3, 3, and from which the conditioned air is supplied. This system aims at air conditioning within the rooms 3 and 3 by sending out air and sucking in room air. In such an air conditioner, a blower for blowing out and sucking air has been provided in the blowing and suction unit 10.10.

(Problems to be Solved by the Invention) Although not shown in the drawings, in an air conditioner having the structure described above,
There is an example in which a blower and suction unit is equipped with one blower only on the blower side. In this case, the resistance of the duct must be taken into account, and a large amount of air is required. However, since the size of the blower and suction unit is already limited, the size of the blower is also limited, and in order to increase the air volume, the number of rotations must be increased. had the disadvantage of increased noise.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a blow-off/suction unit that increases air blowing capacity and produces low noise.

(Means for Solving the Problems) The gist of the present invention is that a rectangular case has a room-side opening communicating with the room and a duct-side opening communicating with the air conditioner, and has A partition plate is arranged to divide the chamber into an upper chamber and a lower chamber, and in the upper and lower chambers, blowers are installed horizontally and in opposite blowing directions to the partition plate, In addition, one motor for rotating both blowers is supported by the partition plate.

(Function) Therefore, the case of the blow-off suction unit is divided into upper and lower chambers, and a blower is installed horizontally in each of these chambers, and the diameter of the fan of the blower is the maximum diameter that can fit inside the unit case. In addition, the capacity can be increased by using two blowers, and the rotation speed can be kept low, thus achieving the above-mentioned purpose.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

1 to 4, a blow-off/suction unit 10 of the present invention is shown. This blow-out suction unit 10 has a case 11 having a substantially rectangular shape, and has a room-side opening 12 facing a room on the front surface and a duct-side opening 13 connecting a duct on the rear surface. This case 11
A partition plate 14 is disposed laterally inside the chamber so that the front side thereof is lowered, and the partition plate 14 divides the chamber into an upper chamber 15a and a lower chamber 15b. As a result.

The room side opening 12 is divided into an upper suction port 12a and a lower blowout port 12b, and the duct side opening 13
is divided into an upper connection port 13a and a lower connection port 13b. A filter 16 is attached to the suction port 12a via a holding plate 17.

The blowers 18a and 18b are arranged in an upper chamber 15a and a lower chamber 15b, respectively, with the partition plate 14 in between.

By rotating these blowers 18a and 18b, conditioned air is blown into the room and at the same time air from the room is sucked in.

The blowers 18a and 18b are provided in a blower case 19a.

19b and centrifugal fans 20a, 20b, the blower case 19a of the blower 18a has its longitudinal direction oriented horizontally, and its lower surface is attached to the partition plate 14 via a mounting piece 23a. and.

It has suction holes 21a, 21a on its upper and lower surfaces, and its blow-off hole 22a faces the upper connection port 13a side.

Note that the blow-off hole 22a is provided with a door 24 that is opened and closed by a drive device described below.

The centrifugal fan 20a is located inside the blower case 19a, arranged horizontally, and rotated by a biaxial motor 25 fixed to the lower surface of the blower case 19a.

The blower case 19b of the blower 18b is also arranged with its longitudinal direction oriented horizontally, and its upper surface is attached to the partition plate 14 with the mounting piece 2.
3b. The lower surface thereof has a suction hole 21b, and the blowout hole 22b is connected to the blowout port 12b.
is being faced.

The centrifugal fan 20b is located inside the blower case 19b, arranged horizontally, and rotated by a biaxial motor 25 fixed to the upper surface of the blower case 19b.

A door 26 is provided at the lower connection port 13b and is used to open and close the door. 27 is the door 2 mentioned above.
This is a drive device that opens and closes 4 and 26, and is operated in the direction of closing when air conditioning in the room is not required, and is linked to the rotation of the blower. In this example, a motor is utilized;
Rod 28a.

28b to the respective door 24.26. 29 is a flange for mounting.

In the above-described configuration, the blow-off suction unit 10 is arranged in one room 3, 3 with its front side open.

A duct provided with air conditioning equipment is connected to the upper connection port 13a and the lower connection port 13b on the rear side.

I am now using the blower 18a to install the air conditioner for one room.

When 18b is rotated, the door 24°26
As shown in FIG. 4, the air blower 18a is opened as shown by the two-dot chain line, and one of the blowers 18a sucks in air from the room, and the suction hole 21a
The air is blown out from the blow-off hole 22a through the upper connection port 13a and into the duct. This air is temperature-controlled by an air conditioner (not shown), passes through the duct again, reaches the lower connection port 13b, flows from the suction hole 21b to the blowout hole 22b, and is blown out into the room from the blowout port 12b. .

When air conditioning becomes unnecessary, the rotation of the blowers 18a and 18b is stopped. This causes the drive device 27 to actuate the door 24.
26 are returned to the solid line positions, as shown in FIG. 4, and each is closed. This will stop unnecessary air conditioning in the room.

In this embodiment, a plurality of blow-off and suction units were provided to air-condition a plurality of rooms.

Obviously, in the case of a single room, the doors 24, 26 are not needed.

(Effects of the Invention) As described above, according to the present invention, since two blowers are arranged laterally, the blowing capacity can be increased compared to every other blower. Moreover, since it was two-stage and horizontally oriented, it was possible to obtain the maximum diameter, which could continue to contribute to an increase in air blowing capacity.

In addition, two blowers are installed, and one blower controls the suction side, and the other blower controls the blowout side, so even if the static pressure changes to a certain degree, the air volume will not change much within the range of use of the fan. There is no such thing.
