Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary heat exchanger such as a rotary total heat exchanger or a rotary sensible heat exchanger, a rotary dry dehumidifier, or the like, which is rotatable over at least two gas passages. The present invention relates to a so-called rotary matrix type air conditioner having a simple rotor.

[0002]

2. Description of the Related Art For example, in the case of a rotary heat exchanger, a rotatable rotor is disposed so as to straddle two gas passages separated by a partition wall, and the rotor is rotated to continuously connect the two gas passages. And pass through (intervene) to exchange heat with each other. In such a case, for the rotational drive of the rotor, for example, a method in which a drive pulley fixed to the drive shaft of the motor and an endless belt or a chain are wrapped around the outer periphery of the rotor to drive the rubber, a rubber pulley fixed to the drive shaft of the motor is directly attached to the outer periphery of the rotor. There is a method of driving by contacting the rotor, and a method of directly driving the rotor shaft itself. In any case, conventionally, one rotor is driven by one motor fixed to a frame housing the rotor. It is supposed to.

[0003]

Therefore, two motors are required to rotationally drive the two rotors. However, if the installation space is limited, physical installation is not possible. May be possible. For this reason, it is naturally conceivable to rotate two rotors with one motor, but simply put a belt between the pulley fixed to the drive shaft of one motor and the two rotors. The following problems occur only by handing.

That is, if the length of the belt changes during rotation of the rotor, or if the degree of concentricity of the rotor varies, since the motor is fixed to the frame, these changes and variations in the belt cannot be absorbed. Abnormal vibration may occur, or loss of transmission of the driving force of the motor may occur, and a predetermined number of rotations of the rotor may not be obtained. (If the degree of concentricity varies, the circumferential surface is uneven. This refers to the condition, which is caused by scratches during the manufacturing process, transportation, and mounting). In addition, when one of the two belts stretched over the two rotors is elongated due to aging or the like, a predetermined number of rotations of the rotor cannot be obtained, and one of the rotors is rotated. Or one of the two belts may be extremely worn or deteriorated.

[0005] The present invention has been made in view of the above points, and has been improved in the portion supporting the motor, so that even if two rotors are rotated by one motor, the length of the belt during operation is reduced. Rotation that can absorb run-out that occurs when the rotor concentricity varies, and can prevent one of the belts from being extremely worn or deteriorated even if the belt is stretched during long-term operation. It is an object of the present invention to provide a matrix type air conditioner to solve the above-mentioned problem.

According to such a rotary matrix type air conditioner, the motor is supported so that the drive shaft is movable across the center line between the two rotors when viewed from the axial direction of the drive shaft on the motor side. Therefore, for example, when the drive shaft is viewed from the front, the drive shaft can be swung right and left. Therefore, even if the length of the belt changes during operation or the degree of concentricity of the rotor varies, it can be absorbed.

In order to support the motor such that the drive shaft on the motor side is movable across the center line between the two rotors, for example, a support member supporting the motor is slidably supported. Or, as will be described later, it can be realized by rotatably supporting about an axis.

The support portion of the motor is rotatable about an axis parallel to the axial direction of each rotor and set at a position equidistant from the axes of the two rotors. A matrix type air conditioner is provided.

According to the rotation matrix type air conditioner having the above-described structure, with respect to an axis set in a position parallel to the axial direction of each rotor and equidistant from the axes of the two rotors,
Since the support portion of the motor is rotatable, even if the belt length changes during operation or the rotor has a varying degree of concentricity, this can be absorbed.

Further, in the rotary matrix type air conditioner according to the third aspect, the support portion of the motor is constituted by a support base and a motor support member to which the motor is attached, and the support base is provided. Is rotatable about an axis parallel to the axial direction of each rotor and set at a position equidistant from the axes of the two rotors, and furthermore, the motor support member is connected via an appropriate urging member. It is supported on the support base. It is more preferable that the urging member urges the motor support member in a direction away from both the shaft centers of the two rotors.

That is, by adopting such a configuration,
In addition to absorbing fluctuations due to variations in belt length during operation and variations in the concentricity of the rotor, the tension of both belts can always be maintained at a balanced angle. Therefore, it is possible to prevent one of the belts from being extremely worn or deteriorated.

In order to urge the motor supporting member away from both axes of the two rotors and to support the motor supporting member on the supporting base, for example, the motor supporting member is moved relative to the supporting base by an appropriate guide member. It may be slidable, and an appropriate biasing member such as a spring or another elastic body may be attached or interposed along the guide member.

A motor support plate having four guide shafts 36 erected on the support base 35 by the fixing means 37 on the motor 31 side and holes (not shown) through which the respective guide shafts 36 can be inserted are formed at four corners. Reference numeral 38 is attached so that each guide shaft 36 passes through the hole (not shown). With such a configuration, the motor support plate 38 can approach and separate from the support base 35 (see a reciprocating arrow in FIG. 5).

A stopper 41 is provided on the top side of each guide shaft 36.
