Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a wall space that forms an attic space and an underfloor space in a house between an outer wall and an inner wall, and a space in a hollow columnar body that is formed indoors. The present invention relates to an indoor air exhaust and circulation device that provides indoor air-conditioning effect and moisture-proof effect by exhausting or circulating indoor air of a house using the entire space as an air passage.

<Prior art> In a conventionally proposed house of this type of air cycle structure, when used in winter, the air warmed by the south wall and the warm air of the attic are placed between the north wall with a wide passage cross-sectional area. However, in this case, the room is heated from the upper part of the room through a large heat transfer area, and the lower part of the room has a rapidly falling air temperature. It will be too low to be warmed. Therefore, only the upper part of the room became warm, and the sufficient heating effect was not obtained. Therefore, the applicant previously disclosed in Japanese Patent Application No. 62-257914 a hollow columnar body that separately connects the attic and the underfloor in a house, and installs a fan in the hollow columnar body or at an appropriate place such as an outlet. We proposed a house with an air cycle structure in which the warm air in the attic was forcibly lowered down and raised through the wall space below the floor to warm the room below the floor and below the wall.

<Problems to be solved by the invention> However, as shown in detail in the prior proposal relating to the above-mentioned patent application,
The air flow in the air passage has different effects in summer and winter because the effect required for the air flow is different, and therefore the air flow is completely different. is there.

It is an object of the present invention to provide a device for easily changing the flow of air so that the air flow can be adapted to the seasons of summer and winter, and for making the flow smooth. Is.

<Means for Solving the Invention> In order to achieve the above object, in the present invention, an attic space (8) and a floor (14) formed between a ceiling (12) and an attic (13) are provided. The underfloor space (9) formed between the ground surface (15) and the wall space (10) formed between the inner wall (16) and the outer wall (17) communicate with each other to form an air passage,
An air passage for descending is formed in which a hollow columnar body (7) that connects the attic space (8) and the underfloor space (9) is provided indoors, and an exhaust path (8) from the attic space (8) to the outdoor (18) is formed. 5) is provided with an exhaust passage opening / closing device (1) and an attic ventilation fan (2), a vertical duct fan (3) is provided in the air passage in the hollow columnar body (7), and an underfloor space (6) is provided in the house foundation (6). 9) An underfloor ventilation hole (4) that opens and closes to the outside (18) is provided, and the temperature sensor (TH) is installed indoors in a place where there is no sudden temperature change with time. The output is obtained as a control signal for opening / closing the exhaust passage opening / closing device (1) and operating the attic ventilation fan (2) and the vertical duct fan (3) to open the exhaust passage opening / closing device (1) when the indoor temperature is high. Activated ventilation fan (2), stopped vertical duct fan (3), underfloor Open the air holes (4), close the exhaust passage opening and closing device (1) when the indoor temperature is low, stop the attic ventilation fan (2), operate the vertical duct fan (3), and close the underfloor ventilation hole (4). As well as
A power source for controlling and operating the temperature sensor (TH), the exhaust passage opening / closing device (1), the attic ventilation fan (2), and the vertical duct fan (3) are connected in parallel to each other with a solar cell (SC) and a storage battery ( B), and an indoor air exhaust and circulation device characterized by being constituted by a power source including a backflow prevention means (D) for preventing current flow from the storage battery side to the solar cell side. is there.

The lower ventilation hole (4) is located at the bottom of the house and is easily accessible.
The opening and closing may be manual. Of course, if economically possible, you can use the temperature sensor (TH) to control.

It is preferable that the exhaust passage opening / closing device (1) has an opening / closing structure with the damper (1a) and the opening / closing device for the underfloor ventilation hole (4) has an opening / closing structure with a shutter because the airtightness of the air passage can be easily maintained. .

In addition, the exhaust path switchgear (1) and each fan always operate in summer and winter, so the main power source is a solar cell, and extra power is stored in a storage battery when solar energy cannot be obtained at night. By doing so, it is possible to save power by effectively using natural energy.

<Operation> When the indoor temperature is high in summer, the exhaust passage opening / closing device (1) is opened by the signal from the temperature sensor (TH), and the attic ventilation fan (2) is operated. And if you open the underfloor ventilation holes (4),
Hot air in the attic is discharged to the outside and cold air enters through the underfloor ventilation hole (4). So the floor, walls,
The ceiling is constantly exposed to relatively cool air, and indoor temperatures do not rise much even in summer.

When the indoor temperature is low in winter, the exhaust passage opening / closing device (1) is also closed by the temperature sensor (TH) and the vertical duct fan (3) is operated. Then, if the underfloor ventilation hole (4) is closed, the air warmed by the heat transmitted from the south side wall or roof and accumulated in the attic lowers the hollow columnar body (7) by the vertical duct fan (3) and moves to the underfloor space ( 9), reach the next wall space (10), go up and circulate through the house. Therefore, the room warms from the bottom of the floor and walls, warming the entire room.

<Examples> Further details of the configuration will be described below based on Examples shown in the drawings.

Fig. 1 shows the exhaust passage opening / closing device (1) as an opening / closing device using a damper (1a). The damper (1a) is opened and closed by a gear motor (1M), and the gear motor (1M) is a limit switch (LS1). , (LS2) to stop the operation.

The thermistor of the temperature sensor (TH) detects seasonal temperature changes and is installed in a place where it is unlikely to be subject to sudden temperature changes over time during the day, such as the northeast corner of the attic.

A sequence diagram of each device shown in FIG. 1 is shown in FIG. 2 (b).

The underfloor ventilation hole (4) has a shutter-type opening / closing structure and is located in the lower part of the house, and it is easily accessible unlike other devices. Therefore, the shutter is opened and closed manually, but of course the same as other devices. It does not matter if the operation is automated. Also, the exhaust passage opening / closing device (1) and the underfloor ventilation hole (4)
Are not limited to those shown in this embodiment, as long as they satisfy these functions.

In the sequence diagram of FIG. 2 (b), the power source is connected in parallel with the solar cell (SC) and the storage battery (B) as shown in the circuit of FIG. 2 (a) from the viewpoint of energy saving and power failure compensation. The DC power supply is provided with a backflow prevention means such as a backflow prevention diode (D) for blocking the flow of current from the storage battery side to the solar cell side.

Since the device of the present invention always operates both in summer and winter, obtaining the power of the sun by converting the light energy of the sun into electric energy is very effective as a power saving measure, and a power failure that is likely to occur in general household power sources. There is no worry. During the daytime, the solar cell (SC) supplies current to each device, and the excess electric energy is stored in the storage battery (B). The storage battery (B) serves as a power source during cloudy weather or after sunset and supplies current to each device.

When the ambient temperature rises, the temperature sensor (TH) closes the a contact (TH-a) of the temperature sensor (TH) and excites the relay coil (MC1) to excite the relay coil a contact (MC1-a).
1), (MC1-a2) and (MC1-a3) are closed, and the b contacts (MC1-b1), (MC1-b2) and (MC1-b3) of the relay coil are opened. Therefore, the gear motor (1M) operates and the motors (2M1) and (2M2) of the attic ventilation fan (2) also operate.

When the exhaust path (5) is opened, the gear motor (1M) hits the limit switch (LS2) to open the b contact (LS2-b) of the limit switch and stop.

Therefore, if the underfloor ventilation hole (4) is opened, as shown in FIG. 4, cold air is discharged to the outside and the temperature in the room is lowered.

When the temperature around the temperature sensor (TH) decreases, the a contact (TH-1) of the temperature sensor (TH) opens, the relay coil (MC1) is demagnetized, and the relay coil a contact (MC1-a1),
(MC1-a2) and (MC1-a3) are opened, and the b contacts (MC1-b1), (MC1-b2) and (MC1-b3) of the relay coil are closed. Therefore, the motors (2M1) and (2M2) of the attic ventilation fan (2) stop, the motor (3M) of the vertical duct fan (3) operates, and the gear motor (1M) operates.

Since the current flow of the gear motor (1M) is opposite, the gear motor (1M) operates in the direction to close the exhaust path (5), and if it closes, hit the limit switch (LS1) and make the b contact (LS1) of the limit switch. -Open b) and stop.

Therefore, if the underfloor ventilation holes (4) are closed, as shown in Fig. 5, the air warmed by the heat transferred from the south side wall and roof and accumulated in the attic moves down the hollow pillar (7). It reaches the underfloor space (9), then rises along the wall space (10), circulating through the house to warm each room.

<Effects of the Invention> As is apparent from the above description, according to the present invention, a single air-cycle structure house provided in a place where the temperature does not change suddenly with time in one day. With a simple control mechanism using a control signal from the temperature sensor, the air flow in the air passage can be easily changed to a completely different flow for summer and winter, and a smooth air flow can be achieved. it can. Therefore, a comfortable habitability can be provided to the house. In addition, the effective use of natural energy by solar cells can reduce the heating and cooling costs. In addition, since warm air is constantly flowing in the air passage, it is possible to suppress local moisture generation and dew condensation, and prevent wood corrosion and steel material rusting.
