Abstract

PURPOSE:To make uniform rightward and leftward air speeds at an air blowing port and prevent air blown from the blowing port from being sucked again into the suction port even in case of a weak air by a method wherein a pair of air-driven plates are arranged between a partition plate and an air direction varying plate and a connecting rod is provided through a spring for connecting both air-driven plates. CONSTITUTION:Interior air is sucked into a main body 11 of an air conditioner through a suction port 12 and then the air is sent to a heat exchanger 14 by an air blower 13. The heat exchanged air is blown upward and slanted by the air direction varying plate 16 during cooling operation and the hot air is fed downward during heating operation. The air-driven plate 18 may receive an air pressure within a blowing port 15 and push a connecting rod 19 through a spring connecting between the right and left air-driven plates 18. The connecting rod 19 is retracted and then the right and left blowing ports 15 are widened. In case that a capability at a low loading operation is adjusted, the number of revolution of the air blower 13 is decreased to reduce an amount of blown air and ten an air pressure within the blowing port 15 is reduced. A force for pushing the connecting rod 19 is reduced, the connecting rod 19 is extended by the spring, the right and left blowing ports 15 are made narrow and an air speed at the blowing ports 15 becomes equal to that of performing a capability adjustment.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a blowing device for a ceiling-mounted air conditioner.

Conventional technology In recent years, in-ceiling type air conditioners have been installed in the ceiling due to market needs for space saving, cost, and non-existence, so the inlet and outlet are close to each other on the ceiling surface. It is in the form of

The above-mentioned conventional blowing device for an air conditioner will be described below with reference to the drawings.

is a suction port for sucking indoor air into the air conditioner main body 1. 3 is a blower for blowing air.

4 is a heat exchanger that removes heat from indoor air to cool the room, or conversely adds heat to heat the room. Reference numeral 6 denotes an outlet for blowing the air conditioned by the heat exchanger 4 into the room again. 6 is a wind direction changing plate for changing the wind direction up and down.

The operation of the air conditioner blowing device configured as above will be described below.

First, indoor air is sucked into the air conditioner main body 1 through the suction port 2, and is blown to the heat exchanger 4 by the blower 3. The air that has passed through the heat exchanger 4 and has been heat exchanged is blown diagonally upward by a wind direction change plate 6 provided in the air outlet 6. During cooling operation, the cool air is blown diagonally upward, and during heating operation, the warm air is blown downward. Blow air to.

Problems to be Solved by the Invention However, in the above configuration, when adjusting the heating and cooling capacity at low loads, the adjustment is made by lowering the rotation speed of the blower 3 and reducing the amount of air passing through the heat exchanger 4. Therefore, especially during heating, the wind speed of the flow a blown into the room from the air outlet 6 becomes weaker, and a part of the flow a is attracted by the flow b sucked into the air inlet 2, causing the air conditioner main body 1 Due to the heating circuit, the required heating capacity cannot be obtained.

In addition, since the wind speed from the outlet 5 is low, the warm air does not reach the feet, resulting in poor comfort.

In view of the above-mentioned problems, the present invention provides a blowing device for an air conditioner that provides the necessary heating capacity even in a weak wind condition during heating operation and allows warm air to reach the feet.

Means for Solving the Problems In order to solve the above-mentioned problems, the blow-off device for an air conditioner of the present invention is provided with blow-off ports on both sides of the suction port, and a wind direction change plate that can change the wind direction approximately in the center of the blow-off ports. A pair of wind movement plates are provided between the partition plate that partitions the suction port and the air outlet and the wind direction changing plate, and a connecting rod via a spring is provided to connect both of the wind movement plates.

Function: With the above-described configuration, the present invention strongly pushes the wind plate when the wind speed from the outlet is strong, so the connecting rod via the spring contracts and the outlet becomes wider.

Furthermore, when the wind speed from the outlet is low, the force pressing down on the wind plate is weak, so the connecting rod is expanded by the elastic force of the spring, and the outlet becomes narrower.

EXAMPLE Hereinafter, a blowing device for an air conditioner according to an example of the present invention will be described with reference to the drawings.

FIG. 1 shows a sectional view of a blowing device for an air conditioner according to an embodiment of the present invention. In FIG. 1, 11 is a ceiling-embedded air conditioner main body.

12 is a suction port for sucking indoor air into the air conditioner main body 1. 13 is a blower for blowing air. 14 is a heat exchanger that removes heat from indoor air to cool the room, or conversely adds heat to heat the room. 1
Reference numeral 6 denotes an outlet 15 for blowing the air conditioned by the heat exchanger 14 into the room again. 16 is a wind direction changing plate for changing the wind direction up and down. 17 is a partition plate that partitions the inside of the suction port 12 and the inside of the blowout port 15. Reference numeral 18 denotes a wind motion plate that can freely swing on one side, and is attached to the partition plate 17. 19 is a connecting rod via a spring that connects the left and right wind plates.

The operation of the air conditioner blowing device configured as above will be described below with reference to FIG. 1.

First, indoor air is sucked into the air conditioner main body 11 through the suction port 12, and is blown to the heat exchanger 14 by the blower 13. The air that has passed through the heat exchanger 14 and has been heat exchanged is blown diagonally upward by the wind direction change plate 16 provided in the air outlet 16, during cooling operation, the cool air is blown diagonally upward, and during heating operation, the warm air is blown downward. Blow air to. At this time, the wind plate 18 attached to the partition plate 17 receives the wind pressure in the air outlet 16 and presses the connecting rod 19 via the spring that connects the left and right wind plates 18, so the connecting rod 19 contracts. .

As a result, the left and right air outlets 16 widen. By the way, when performing capacity adjustment at low load, the rotational speed of the blower 3 is lowered to reduce the air volume, so the wind pressure inside the outlet 16 is also reduced. Therefore, the force pressing the connecting rod 19 that connects the airflow plates 18 is reduced, and the connecting rod 19 is extended by the spring force within the connecting rod 19, and the left and right air outlets 16 become narrower. Therefore, the wind speed at the air outlet 16 is the same as before the capacity adjustment.

As described above, according to this embodiment, the air outlet 16 is provided on both sides of the air inlet 12, and the air direction changing plate 16, which can change the air direction, is provided approximately at the center of the air outlet 16, and the air outlet 16 is partitioned from the air outlet 16. A wind movement plate 18 is provided between the partition plate 17 and the wind direction changing plate 16.
By providing a connecting rod 19 via a spring that connects both of the wind movement plates 16, it is possible to equalize the wind speed of the left and right air outlets 16, and to obtain a constant wind speed regardless of the increase or decrease in the air volume. It will be done.

Effects of the Invention As described above, the present invention provides air outlets on both sides of the air inlet, a wind direction changing plate that can change the wind direction approximately in the center of the air outlet, and a partition plate that partitions the air inlet and the air outlet, and the wind direction. By providing a pair of wind motion plates between the changing plates and a connecting rod via a spring that connects both of the wind motion plates, the wind speed on the left and right sides of the outlet becomes uniform, and even in weak winds, the air flow from the outlet The blown air is no longer sucked into the suction port again.

Furthermore, the wind speed can also be improved, so comfort can be improved.
