Abstract

PURPOSE:To provide an air conditioner which can send air stably in accordance with the change in draft resistance. CONSTITUTION:In an air conditioner 1, the flow of air from a heat exchanger 3 formed by the rotation of rotating blade 2 is sent out through a discharge port 5 after being stabilized by a stabilizer 4. The stabilizer 4 can be moved in connection with the drive of motor. The drive of motor is controlled in accordance with the draft resistance of heat exchanger 3 and air supply amount. Thus, the gap G1, G2 between the rotating blade 2 and the stabilizer 4 can be varied by the movement of stabilizer 4.

Description

[Field of Industrial Application] The present invention relates to an air conditioner in which the flow of air from a heat exchanger, which is formed by the rotation of rotor blades, is stabilized by a stabilizer and then blown from an outlet. be.

0002

[Prior Art] Generally, an air conditioner 6 as shown in FIG.
It has been known. That is, the air conditioner 6 is configured such that the flow of air from the heat exchanger 3, which is formed by the rotation of the rotor blades 2, is stabilized by the stabilizer 7 and then blown from the outlet 5. Note that 8 is a drain pan provided at the lower end of the heat exchanger 3, and is configured to collect dew condensation water.

Conventionally, the rotor blades 2 of such an air conditioner 6 have been fixed at a specific position within the casing 60. The stabilizer 7 was fixed so as to maintain a predetermined gap G between it and the rotary blade 2.

[Problems to be Solved by the Invention] By the way, when heating and cooling is performed using such an air conditioner 6, the ventilation resistance of the heat exchanger 3 is 1.5 times higher during cooling than during heating for the same air volume. become.

Therefore, when the rotor blade 2 and the stabilizer 7 are fixed so as to maintain a predetermined gap G, as in the conventional air conditioner 6 described above, there is On the other hand, there was a problem that the optimum air blowing characteristics could not be obtained.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an air conditioner that can stably blow air in response to changes in ventilation resistance.

[0007]

[Means for Solving the Problems] The air conditioner of the present invention includes:
An air conditioner configured to stabilize the flow of air from a heat exchanger formed by the rotation of rotary blades using a stabilizer and send the air from an outlet, the stabilizer being interlocked with a motor drive. The motor drive is controlled according to the ventilation resistance of the heat exchanger and the amount of air blown, and the movement of the stabilizer thereby causes
The gap between the rotor and the stabilizer is changed.

[0008]

[Function] According to the air conditioner of the present invention, the stabilizer is movable in conjunction with the motor drive, and the motor drive is controlled according to the ventilation resistance of the heat exchanger and the amount of air blown. The gap between the rotor blade and the stabilizer is designed to change, so when the ventilation resistance is large, such as during cooling or strong wind operation, the stabilizer can be moved to reduce the gap between the rotor blade and the stabilizer. let This increases the static pressure and provides the necessary air volume. Also,
When ventilation resistance is small, such as during heating or low-wind operation, the stabilizer is moved so that the gap between the rotary blade and the stabilizer becomes larger. This reduces static pressure and allows air to be blown at an optimal air volume with low noise.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show the main parts of the air conditioner 1 under different operating conditions.

That is, this air conditioner 1 has rotor blades 2
The air flow from the heat exchanger 3, which is formed by the rotation of This rotation allows the gaps G1 and G2 between the rotary blades 2 and the stabilizer 4 to change in accordance with the ventilation resistance of the heat exchanger 3 and the amount of air blown.

[0012] The rotor 2 is fixed at a predetermined position in the casing 10. The rotary blade 2 rotates at an appropriate rotational speed depending on operating conditions, forms a flow of air from the heat exchanger 3, and blows the air from the outlet 5.

The heat exchanger 3 is provided upstream of the rotary blade 2 and is designed to cool and heat the air passing through the casing 10. Further, a drain pan 8 is provided at the lower end of the heat exchanger 3, and the drain pan 8 collects dew condensation water within the casing 10.

The stabilizer 4 has a rotation center 41 coaxial with the rotor 2 and is fixed at a predetermined distance from the rotor 2. This rotation center 41 is provided at a position eccentric from the center position of the stabilizer 4. Moreover, the drive of a motor (not shown) is transmitted to this rotation center 41. The stabilizer 4 is rotated by driving this motor (not shown). At this time, since the center of rotation of the stabilizer 4 is eccentric, a gap G1 and a gap G2 larger than this gap G1 are formed between the stabilizer 4 and the rotor blade 2. being done.

Next, the operation of this air conditioner 1 will be explained.

First, in operating conditions where ventilation resistance is large, such as during cooling or strong wind operation, as shown in FIG. 1, the stabilizer 4 is rotated by driving a motor (not shown) to close the gap. In the G1 state, the space between the stabilizer 4 and the rotor blade 2 is made smaller. This results in
The static pressure will increase and the required air volume will be obtained.

Next, in an operating state where the ventilation resistance is small, such as during heating or weak wind operation, as shown in FIG. 2, the stabilizer 4 is driven by the motor (not shown) as shown in FIG. Rotate 180 degrees from the original position and adjust the gap G.
In state 2, the distance between the stabilizer 4 and the rotary blade 2 is increased. This reduces static pressure and allows air to be blown at an optimal air volume with low noise.

In this embodiment, the gap G1 and the gap G2 are changed by rotating the stabilizer 4, but this gap can be changed by sliding the stabilizer 4 linearly. may be configured.

[0019]

As described above, according to the present invention, when the ventilation resistance is large, the required air volume can be obtained, and when the ventilation resistance is small, the optimal air volume can be achieved with low noise. Since ventilation can be performed, stable ventilation can be performed in response to changes in ventilation resistance, and low-noise air conditioning is also possible.
