Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heat exchange type ventilation device.

[0002]

[Prior Art]

 As a conventional heat exchange type ventilator, for example, one configured as shown in FIG. 4 is known. Referring to the drawings below, this heat exchange type ventilator is constructed by alternately laminating corrugated sheets and liners, and the wave directions of the corrugated sheets 2 and 3 which are adjacent to each other via the liner 1 are different. It is configured to be orthogonal to each other. In this way, a heat exchange type ventilation device having a rectangular planar shape formed by alternately laminating a large number of liners 1 and a large number of corrugated plates 2 and 3 is attached to, for example, a wall that separates the inside and the outside of a building. At that time, one half of the ventilation device is projected outside and the other half of the ventilation device is projected indoor when the ventilation device is divided into two equal parts with one diagonal line as a boundary.

[0003]

[Problems to be solved by the device]

 When the room is ventilated using the above ventilation device, the passage 2a of the corrugated plate 2 and the passage 3a of the corrugated plate 3 are orthogonal to each other, and the passage 2a directed in the direction of the arrow X is for exhausting air from the room The passage 3a facing the direction of the arrow Y serves as an inflow passage for outdoor air. The passages 2a and 3a facing in the directions of the arrows X and Y are adjacent to each other through the liner 1, and the heat of the indoor air passing through the passage 2a is transferred to the heat of the outdoor air passing through the passage 3a through the liner 1. So-called heat exchange is performed to suppress changes in indoor temperature.

However, in the above conventional ventilation device, the cross-sectional area of each passage formed by one corrugated plate and the upper and lower liners is small, and the resistance of the air flowing in the passage is large, There was a problem that the air flow rate was small.

The present invention solves such a problem, and an object thereof is to reduce the air resistance flowing in the passage and to increase the air flow rate.

[0006]

[Means for Solving the Problems]

 In order to solve this problem, the present invention interposes a corrugated plate in the space between the sheets that are stacked one above the other, and the corrugated plate is divided at appropriate places in the width direction of the space to allow air to flow into the space. The passages are formed, and the air passages are configured so that they are oriented in directions orthogonal to each other in the vertical direction.

[0007]

[Action]

 With this configuration, the cross-sectional area of each passage formed between the upper and lower sheets can be made sufficiently large, so that the resistance of the air flowing in each passage can be reduced and the ventilation amount can be increased. ..

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1 to FIG. 3, 11 is a liner (sheet) which is arranged in a stacked state in the vertical direction and has a substantially square planar shape. One to three peaks are provided between the liners 11 and 11 which are vertically adjacent to each other. A corrugated plate 12 having about one degree is provided. Specifically, a corrugated plate 12 is provided in the space between the liners 11 and 11 at the center and both sides in the width direction so as to be attached to the liner 11. Therefore, a passage 13 without a corrugated plate is formed between the central corrugated plate 12 and the corrugated plates 12 on both sides.

Therefore, as described above, the lengthwise direction of the corrugated plate 12 interposed in the space between the upper liners 11 and 11 stacked in the vertical direction and the space between the lower liners 11 and 11 are interposed. The corrugated plate 12 is formed so that its length direction is orthogonal to each other. In such a manner, the liner 11 is laminated with the corrugated plate 12 interposed therebetween, and the passage 13 directed in the arrow X direction and the passage 13 directed in the arrow Y direction are alternately formed in multiple stages to form a block-shaped ventilation device. Is configured.

Therefore, this block-shaped ventilation device is attached to the wall that separates the interior and the exterior of the building. At that time, the ventilation device is divided into two equal parts with one diagonal line as a boundary when viewed from a plane. Install so that one half of the box projects outside the room and the other half projects inside the room.

Then, when the indoor ventilation is performed using the above ventilation device, the passage 13 pointing in the direction of the arrow X serves as an exhaust passage for the air in the room, and the passage 13 pointing in the direction of the arrow Y inflows the air outside the room. It becomes a passage. The width of each of the passages 13 is sufficiently large, and the cross-sectional area of each passage 13 is significantly larger than the cross-sectional area of the corrugated passage as described in the conventional example, and the resistance of the air flowing in each passage 13 is reduced. It is possible to obtain a sufficient amount of ventilation. In this embodiment, the air flows through the small passages 14 of the corrugated plate 12 itself as well as the passages 13 between the corrugated plates 12.

By the way, synthetic resin, paper or the like is used as the material of the liner 11 and the corrugated plate 12 which constitute the ventilation device, and the material is selected according to the application. That is, when heat exchange between the outflowing indoor air and the inflowing outdoor air is required, it should be made of synthetic resin such as vinyl chloride, and when both heat exchange and humidity exchange are required. It just needs to be made of hygroscopic paper. Further, even if a hygroscopic material is mixed with the resin, it is possible to impart hygroscopicity.

[0013]

[Effect of the device]

 As described above, according to the present invention, the cross-sectional area of each passage formed between the upper and lower sheets can be made sufficiently large, so that the resistance of the air flowing in each passage can be reduced and the ventilation amount can be increased. Can be planned.
