[0001]

BACKGROUND OF THE INVENTION The present invention relates to a plurality of heat storage elements capable of storing and releasing heat by exchanging heat with a contact fluid in a space between an outer wall and an inner wall. And a discharge port capable of discharging the contact fluid brought into the space and brought into contact with the heat storage body into the room, and a suction port which sucks the contact fluid into the space from the intake port. The present invention relates to a heat storage wall structure provided with a fan for discharging air from a heat storage wall.

[0002]

2. Description of the Related Art Conventionally, as this type of heat storage wall structure, as shown in FIG. 11, an inlet 20 and a discharge port 21 are formed in an inner wall body 2 facing a room, and a heat storage body is formed. 3
Is installed in the space D between the outer wall body 1 and the inner wall body 2 when the inner wall body 2 is formed, and after the inner wall body 2 is attached, it cannot be put in and out of the space D. . However, according to such a heat storage wall structure, for example, when it is necessary to take out the heat storage body from the space for maintenance inspection or replacement of the heat storage body, it is necessary to first remove the inner wall body, After the heat storage body is put back into the space, construction such as re-installation of the inner wall body is required again, and there has been a problem that taking the heat storage body in and out of the heat storage wall is very troublesome.

As a method for solving such a problem, an opening having a size that allows the heat storage body 3 to be taken in and out is provided in the inner wall body 2, and after the inner wall body 2 is attached, the inner wall cover is opened and closed to open and close the heat storage body. There is a method that can be taken out.

[0004]

However, the formation of a large opening in the inner wall and the attachment of the inner wall lid is a problem in design because it detracts from aesthetics. It was a request of the industry to make the department as small as possible.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a heat storage wall structure which can solve the above-mentioned problems and can make the opening as small as possible while ensuring the operability of inserting and removing the heat storage body from the heat storage wall. is there.

[0006]

A feature of the present invention to achieve the above object is that a plurality of heat storages capable of storing and radiating heat by exchanging heat with a contact fluid in a space between an outer wall and an inner wall. Body, an inlet capable of taking the contact fluid from the room into the space, an outlet capable of discharging the contact fluid brought into the space and brought into contact with the heat storage body into the room, and the contact fluid. In a heat storage wall structure provided with a fan for sucking into the space from the inlet and discharging from the discharge port, the heat storage body can pass through at least the lower part of the inlet or the discharge port. A rotatable member is provided above the space to wind the rigging, and the rigging is connected to a plurality of the heat storage bodies so that the rotatable member can be freely taken in and out by rotating the rotator. There It is in place. Where "rigging"
Is used in the sense that it includes chains, chains, belts, etc.
Any material can be used as long as the heat storage body can be suspended.

In the above structure, it is preferable that the rotating body is constituted by a pulley, the rigging is formed endlessly, and a rotation preventing mechanism is further provided from the operation and effect described later. Here, the pulley may have a gear or the like that can be used for a chain, a chain, or the like, in addition to a normal rope pulley. Further, the rotation preventing mechanism may be provided with a rotation preventing mechanism on the pulley itself, or may be provided with a fixing member on the cord and fixed on a wall surface or the like in the space.

It is preferable that a driving means for rotating the rotating body is provided from the viewpoint of the function and effect described later. The driving means is not limited to the automatic type, but may be a manual type.

[Operation and Effect] According to the above configuration of the present invention,
Since the heat storage body is formed so as to be able to pass through at least the intake port or the discharge port that exists at least below, without forming a large opening in the inner wall,
From there, the regenerator can be introduced into the space. And since a rotator is provided and wound around the upper part of the space, and the rigging is connected to the plurality of heat storage bodies, the rotation of the rotator in the pulling-up direction causes
By pulling up the rigging, the heat storage body can be introduced into the space. Further, when taking out the heat storage body, the plurality of connected heat storage bodies can be taken out in the opposite direction by rotating the rotating body in the reverse direction. As a result, it was possible to provide a heat storage wall structure in which the opening can be made as small as possible while ensuring the operability of inserting and removing the heat storage body from the heat storage wall.

In the case where the rotating body is constituted by a pulley, the rigging is formed endlessly, and a rotation preventing mechanism is further provided,
By wrapping an endless rigging around the pulley and connecting the heat storage body below the pulley and pulling the return side rigging, the rotating body rotates smoothly and the heat storage body can be introduced.
After the introduction, the rotation of the rotating body is suppressed by the rotation preventing mechanism, and the heat storage body can be held at the introduction position. At the time of taking out, by releasing the rotation prevention mechanism and allowing the pulley to rotate, the heat storage body can be taken out in the reverse order to the order at the time of introduction.

When the driving means for rotating the rotating body is provided, the heat storage body can be more easily taken in and out of the heat storage wall by the rotational force transmitted from the driving means. Also, by stopping the rotation of the driving means, it is possible to prevent the heat storage body from falling due to the rotation of the rotating body.
