Abstract

PURPOSE: To reduce noises by arranging a partition plate inside a cylindrical rotor for dividing a flow passage inside the rotor plurally, arranging stabilizers in the vicinity of the rotor for stabilizing swirls generated in the divided flow passages, and thereby reducing depth of a box or enlarging a diameter of the rotor. CONSTITUTION: A partition plate 5 is arranged inside a rotor 1 for dividing a flow passage in the rotor into plural parts. Baffle plates 12a, 12b aligned to ends of the partition plate 5 across the rotor 1 and stabilizers 3a, 3b for stabilizing swirls 2a, 2b generated in divided flow passages 6A, 6b are arranged in the vicinity of the rotor 1. When the rotor 1 is rotated, the swirls 2a, 2b are generated to form two flow lines. One flow A is flowed into the passage 6a, energized and flowed out through a flow passage 7a. The other flow B is flowed into the passage 6b, energized and flowed out through a flow passage 7b.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a once-through fan and an integrated air conditioner having the same.

[0002]

2. Description of the Related Art An example of a conventional once-through fan is shown in FIG. The once-through fan includes a cylindrical rotor 1, a stabilizer 3 of 1 and an air guide plate 12, and stabilizes the vortex 2 generated by the rotation of the rotor 1 in one place by the stabilizer 3 to guide the fluid. It flows out along the plate 12.

An example of a conventional integrated air conditioner is shown in FIG. The inner side of the chamber 14 is formed by the partition wall 15 inside the chamber 8
The indoor heat exchanger 10 and the cross-flow fan 20A are arranged in the indoor side chamber 8, and the outdoor heat exchanger 11 and the cross-flow fan 20B are arranged in the outdoor side chamber 9. There is.

During operation of this air conditioner, indoor air is sucked into the indoor side chamber 8 through the suction port 16 and cooled or heated by passing through the indoor heat exchanger 10, and then guided by the partition wall 15 to flow through. After being sucked into the rotor 1A of the fan 20A and being biased there, it is blown out into the room from the blow-out port 18 limited by the stabilizer 3A and the partition wall 15.

At the same time, the outside air is sucked into the outdoor chamber 9 through the suction port 17 and is heated or cooled by passing through the outdoor heat exchanger 11, and then guided by the partition wall 15 to guide the flow-through fan 20B. After being sucked into the rotor 1B and being biased there, it is discharged into the atmosphere from the blow-out port 19 limited by the stabilizer 3B and the partition wall 15.

[0006]

Since the conventional through-flow fan forms only one fluid flow, the fluid flows in from one direction and flows out in one direction. Therefore, the conventional integrated air conditioner requires the once-through fan 20A for urging the indoor air and the once-through fan 20B for urging the outside air, and also needs the motor for individually driving these. However, there is a problem that not only the structure becomes complicated and the cost increases, but also the depth of the device casing 14 becomes large.

[0007]

The present invention has been invented in order to solve the above-mentioned problems. The gist of the first invention is that the flow inside the rotor is inside a cylindrical rotor. A through-flow fan characterized in that a dividing plate for dividing the passage into a plurality of portions is arranged and a stabilizer for stabilizing vortices generated in each of the divided passages is arranged outside the rotor in the vicinity thereof. It is in.

The cross-flow fan according to the present invention is characterized in that a wind guide plate which is aligned with an end of a dividing plate that divides the flow path in the rotor into two is provided outside the rotor in the vicinity thereof. There is something I did.

The gist of the second invention is that a partition wall for partitioning the interior of the chamber into an indoor side chamber and an outdoor side chamber, an indoor heat exchanger arranged in the indoor side chamber, and the outdoor chamber. In an integrated air conditioner having an outdoor heat exchanger arranged in, the through-flow fan according to claim 2 is arranged in the device casing, and the partition wall is constituted by the air guide plate and the dividing plate. It is in an integrated air conditioner characterized by that.

[0010]

According to the first aspect of the invention, a plurality of flows are formed by the rotation of the rotor, and the fluid is sucked into the plurality of divided flow passages in the rotor from a plurality of directions and then urged in a plurality of directions. Spill to.

In the second aspect of the invention, by driving the once-through fan, the indoor air flows through the indoor side chamber,
Outside air flows through the outdoor room.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENT One embodiment of a once-through fan according to the invention is shown in FIG. Inside the rotor 1, a dividing plate 5 for dividing the flow path in the rotor into a plurality of (two in the drawing) is arranged. Outside the rotor 1, air guide plates 12a and 12b which are close to the rotor 1 and are aligned with the respective ends of the split plate 5 with the rotor 1 interposed therebetween.
And stabilizers 3a and 3b for stabilizing the vortices 2a and 2b generated in the divided flow paths 6a and 6b are installed.

However, when the rotor 1 is rotationally driven, a vortex is generated.
2a and 2b are generated and two streams are formed. One flow A flows into the flow path 6a and is energized, and flows out through the flow path 7a which is limited between the stabilizer 3a and the baffle plate 12a. The other flow B flows into the flow path 6b and is energized, and the stabilizer B
It flows out through the flow path 7b which is limited between the 3b and the baffle plate 12b.

FIG. 2 shows an integrated air conditioner using the once-through fan. One flow-through fan 20 is a device case 14
A partition wall that is disposed inside and that divides the indoor side chamber 8 and the outdoor side chamber 9 by the baffle plates 12a and 12b and the dividing plate 5 is configured.

When the rotor 1 of the once-through fan 20 is rotationally driven, the indoor air flows through the indoor heat exchanger 10 from the suction port 16 and enters the divided flow passages 6b in the rotor 1 to be urged. After that, it is blown out into the room through the outlet 18.

At the same time, the outside air flows through the outdoor heat exchanger 11 from the suction port 17 into the divided flow passages 6a in the rotor 1 to be urged, and then discharged from the blow-out port 19 to the atmosphere. It

In the above embodiment, the flow path in the rotor 1 is divided into two by the division plate 5, but if the division is divided into three or more and the corresponding number of stabilizers are arranged, then three or more. Further fluid flows can be formed.

[0018]

According to the first aspect of the present invention, a plurality of flows are formed by the rotation of the rotor, and the fluid is sucked from a plurality of directions into a plurality of divided flow paths in the rotor and is urged. Spill in multiple directions.

In the second aspect of the invention, both the indoor air and the outside air can be urged by driving the once-through fan. As a result, only one through-flow fan and a motor for driving the same can be used, so that not only the structure can be simplified but also the weight and the cost can be reduced.

Further, since the depth of the casing cannot be reduced, otherwise the diameter of the rotor can be increased to reduce the number of revolutions thereof, so that the noise accompanying the operation of the once-through fan can be reduced.
