Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ventilation cylinder installed at a ventilation opening of a wall and a ventilation system for heat-receiving a wall using the ventilation cylinder.

[0002]

[Prior art]

 In recent years, houses tend to have high heat insulation and high airtightness. In such buildings, planned ventilation is necessary to secure the required ventilation. There are two types of planned ventilation: central ventilation (including heat exchange) in which air is supplied and exhausted using ducts, and an exhaust fan as the ventilation driving force.

[0003]

[Problems to be solved by the device]

 The central ventilation is expensive because it is necessary to install a duct. Therefore, a simple ventilator using a ventilation fan is generally used in regions other than the regions requiring heat exchange, such as cold regions. However, the system that exhausts or inhales with a ventilation fan directly introduces the outside air, so there is a problem that improvement of energy saving effect and comfort cannot be expected.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a ventilation tube and a ventilation device using the same, which can achieve great effects such as energy saving and improvement of comfort. .

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the present invention, an outer cylinder and an inner cylinder are rotatably fitted, and the outer cylinder and the inner cylinder are provided with intake ports so that end faces and peripheral faces are staggered, respectively. If the inlets on one side are matched, the other inlet is closed.

In addition, the ventilation cylinder is attached to the ventilation port of a wall body which is provided with a ventilation port in the upper part and forms an air layer inside so that the air layer can communicate with the ventilation port. is there.

【Example】

 A description will be given below based on the illustrated embodiment. Reference numeral 1 denotes a ventilation cylinder. The ventilation cylinder 1 is formed in a cylindrical shape, and is composed of an outer cylinder 2 and an inner cylinder 3 rotatably fitted in the outer cylinder 2. ing.

The outer cylinder 2 has an end face portion 4 formed at an outer end thereof, and two quadrant-shaped fan-shaped air inlets 5 are opened in the end face portion 4 so as to face each other. Two intake ports 5 occupying a quarter and two unopened portions 6 occupying a quarter of the entire end face portion are formed. In addition, a rectangular inlet port 8 is opened on the peripheral side face 7 adjacent to the inlet port 5 of the end face portion 4 along the circumferential direction, and the length of the inlet port 8 is the entire circumference of the peripheral side face. It is about 1/4 of that.

The inner cylinder 3 has an end surface portion 9 formed at the outer end, and like the outer cylinder 2, two quadrant-shaped fan-shaped air inlets 10 are formed in the end surface portion 9 so as to face each other. There are two intake ports 10 that occupy about a quarter of the entire end face portion, and two unopened portions 11 that occupy a quarter of the end face portion. Further, a rectangular intake port 13 is opened along the circumferential direction on the peripheral side face 12 at a position adjacent to the unopened portion 11 of the end face portion 9 and at a position shifted from the intake port 8 of the outer cylinder 2 by a quarter. The length of the intake port 13 is about a quarter of the entire circumference of the peripheral side surface.

The inner cylinder 3 configured as described above is rotatably fitted to the outer cylinder 2, and the intake port 5 of the outer cylinder 2 and the intake port 10 of the inner cylinder 3 are displaced from each other so that the ventilation cylinder 1 has In the state where the end face portion is closed, the intake port 8 of the outer cylinder 2, the inner cylinder 3 and the intake port 13 coincide with each other, and the peripheral side surface portion of the ventilation cylinder 1 opens (FIGS. 2 and 4). Further, in a state in which the intake port 5 of the outer cylinder 2 and the intake port 10 of the inner cylinder 3 are aligned and the end face portion of the ventilation cylinder 1 is opened, the intake port 8 of the outer cylinder 2 and the intake port 13 of the inner cylinder 3 are opened. The ventilating cylinder 1 is configured so that it is displaced and the peripheral side surface of the ventilation cylinder 1 is closed (FIGS. 3 and 5).

The ventilation cylinder 1 is fitted into the ventilation port 15 of the wall body 14 with the end surface portion 4 of the outer cylinder 2 exposed to the outside. In this case, the outer cylinder 2 is fixed so that the intake port 8 on the peripheral side surface 7 faces downward. The wall body 14 is formed so as to introduce the outside air at the lower part, and the exterior material 16 and the interior material 17 are attached with a space therebetween. Inside, the heat insulating material 18 is attached along the interior material 17. There is provided an air layer 19 that communicates vertically between the heat insulating material 18 and the exterior material 16, and this air layer 19 communicates with the ventilation port 15 at the upper part.

The wall 14 provided with the ventilation cylinder 1 rotates the inner cylinder 3 as shown in FIG. 2 during the daytime and the nighttime of the winter season so that the intake port 8 of the outer cylinder 2 and the inner cylinder 3 are rotated. If the intake port 13 is matched, the peripheral side surface of the ventilation cylinder 1 opens downward and the end surface portion is closed. Therefore, as shown in FIG. 4, the room 20 is shielded from the outside air, and the air layer 19 and the ventilation pipe 1 communicate with each other in the wall body 14, and further the room 20 communicates with each other. During the daytime in winter, the temperature of the air layer 19 is heated to the same or higher than the room temperature through the exterior material 16 on the outer wall surface exposed to the sunlight. Therefore, the outside air heated through the air layer 19 rises and is introduced into the room 20 through the ventilation cylinder 1. In addition, even at night, the outside air is introduced from the air layer 19 to recover the accumulated heat in the daytime and the heat dissipated through the heat insulating material 18.

However, in the summer, the temperature of the air layer 19 becomes high and adversely affects the room 20. Therefore, the inner cylinder 3 is rotated as shown in FIG. If it matches the intake port 10 of the cylinder 3, the end surface portion of the ventilation cylinder 1 is opened and the peripheral side surface is closed. Therefore, as shown in FIG. 5, the outdoor space 21 and the indoor space 20 communicate with each other, and the air layer 19 and the ventilation cylinder 1 are cut off, so that the outside air is directly introduced without passing through the air space 19.

[Effect of device]

 As described above, the ventilation cylinder of the present invention has a simple structure in which the outer cylinder and the inner cylinder, which are alternately provided with the intake ports, are rotatably fitted, and the intake side can be changed by a simple operation of rotating the inner cylinder. You can

Further, in the wall-heat-receiving / utilizing ventilator according to claim 2 in which this ventilation cylinder is installed, a simple device is provided by introducing outside air heated by solar radiation during the winter days into the room through the air layer in the wall. However, it is possible to save energy and improve comfort. In addition, even in the winter night, introducing outside air from the air layer has the effect of recovering the heat accumulated during the day and the heat escaping through the heat insulating material. Furthermore, it is possible to perform intake air that is not easily affected by the external wind speed throughout the day and night. Furthermore, in the summer, the outside air can be introduced directly into the room without passing through the air layer, so that it can easily respond to environmental changes in the summer and winter and day and night, and can save energy and comfort with almost no increase in equipment cost. It is possible to obtain a great effect such as improving the tendency.
