Abstract

PURPOSE:To provide the comfortable habitability of a house by a method wherein the flow of air in an air passage matches each of that during the summer and that during the winter and the flows being completely different from each other are produced. CONSTITUTION:At an indoor high temperature period during the summer season, by means of a signal from a temperature sensor TH, a discharge passage opening and closing device 1 is opened, and an attic ventilating fan 2 is actuated. By opening an underfloor ventilating hole 4, hot air in an attic is discharged to the outside and cold air flows through an underfloor ventilating hole 4. Therefore, even during the summer season, temperature in a room is not increased to so high value. At an indoor low temperature period during the winter season, a discharge passage opening closing device 1 is closed by means of a temperature season TH, and a vertical duct fan 3 is actuated. By closing the underfloor ventilating hole 4, air heated by heat transmitted from a wall and a roof on the south and residing in an attic descends from the vertical duct fan 3 through a hollow columnar body 7 to an underfloor space 9. The air is raised along a wall space 10 and circulated in a house. This constitution forces a room to be warmed from a floor and the lower part of a wall and throughout the whole of the room.

Description

[Detailed Description of the Invention] Industrial Application Fields The present invention relates to a wall space that forms an attic space and an underfloor space between an outer wall and an inner wall of a house, and a hollow columnar space that is formed indoors. This invention relates to an indoor air exhaust and circulation device that provides indoor cooling/heating effects and moisture-proofing effects by communicating with each other and exhausting or circulating the indoor air of a house using the entire space as an air passage.

Conventionally, as the applicant stated in Patent No. 257914 of 1962, for houses with this type of air cycle structure, when used in winter, the air warmed by the south wall and the warm attic are Since the air descends between the walls on the north side, which has a wide cross-sectional area, the room is heated from the top of the room through a large heat transfer area, and the bottom of the room is heated by the descending air. The temperature drops quickly, making it difficult to warm up. Therefore, only the upper part of the room becomes warm and a sufficient heating effect cannot be obtained. Therefore, in the above patent application, the applicant separately installed a hollow columnar body in the house that communicates the attic and the underfloor, and A fan is installed inside the room or at an appropriate location such as at the exit to force the warm air from the attic down and rise from under the floor through the wall space, making the room warmer than at the bottom of the floor or wall.

Problem to be Solved by the Invention> However, as detailed in the above patent application, the air flow within the air passage has different effects in summer and winter, so the flow is completely different. Therefore, it is necessary to adjust the air flow to suit the season.

The purpose of the present invention is to provide a device for easily changing the air flow and making the air flow suitable for each season of summer and winter. It is.

Means for solving the above problems〉 In order to achieve the above purpose, the ceiling (12) and the attic (
13) and the attic space (8) and the floor (l4
) and the ground (15) through a wall space (10) formed between the inner wall (16) and the outer wall (17), and the attic. In the air passage formed by the hollow columnar body (7) that communicates the space (8) and the underfloor space (9), an exhaust passage opening/closing device is installed in the exhaust passage (5) leading from the attic space (8) to the outdoors (18). (1) and the attic ventilation fan (2), the hollow columnar body (
7) A vertical duct fan (3) is installed in the upper part, and an openable and closable underfloor ventilation hole (4) that leads from the underfloor space (9) to the outdoors (18) is installed in the house foundation (6).

The combination of operating states of the exhaust passage opening/closing device (1) and each fan is determined in the summer and winter seasons, as described below. It is now possible to distinguish between winter driving modes, so the ?Wx degree sensor (THE
) is used as a control signal for opening and closing the exhaust duct opening/closing device (1) and operating the attic ventilation fan (2) and vertical duct 1/fan (3). Open the device (1), operate the attic ventilation fan (2), stop the vertical duct fan (3), open the underfloor ventilation hole (4), and turn on the exhaust duct opening/closing device (1) when indoor temperatures are low in winter.
Close the attic ventilation fan. Stop the fan (2), operate the vertical duct fan (3), and close the underfloor ventilation hole (4). The underfloor ventilation hole (4) is located at the bottom of the house and is easily accessible, so it may be closed manually during that time. Of course, if it is economically possible, the temperature sensor (THE) may be used for control.

If the exhaust passage opening/closing device (1) is configured to be opened and closed by a damper (lm), and the opening/closing device for the underfloor ventilation hole (4) is configured to be opened/closed by a shutter, the airtightness of the air passage will be sufficient.

In addition, since the exhaust ISL switchgear (1) and each fan operate constantly in both summer and winter, the power source is a solar battery, and excess power is stored in a storage battery for when solar energy is not available, such as at night. By doing so, it is possible to save power by effectively utilizing natural energy.

Function> When the indoor temperature is high in summer, the exhaust passage U closing device (1) is opened by a signal from the temperature sensor (TH), and the attic ventilation fan (2) is activated. If you open the underfloor ventilation hole (4), hot air from the attic will be exhausted outside, and cold air will enter through the underfloor ventilation hole (4). Therefore, the floor of the house,
The walls and ceiling are constantly exposed to relatively cold air,
Even in summer, the indoor temperature does not rise much.

When indoor temperature is low in winter, the temperature sensor (TH{)
The exhaust passage opening/closing device (1) closes and the vertical duct fan (3) operates. And under the floor! 1! When the pores (4) are closed, the air warmed by the heat transmitted from the south wall and roof and accumulated in the attic is moved down the hollow columnar body (7) by the vertical duct fan (3) and into the underfloor space (9). then rises along the wall space (10) and circulates around the house. Therefore, the room is heated from the bottom of the floor and walls, making the entire room warm.

Example Hereinafter, details will be explained based on embodiments shown in the drawings.

Figure 1 shows the exhaust passage opening and closing I! (1) to the damper (lm
), the damper (1a) is opened and closed by a gear motor (IM), and the damper (1a) is opened and closed by a gear motor (IM).
M) is a limit switch (LSI), (LS2) that stops the operation.

The thermistor of the temperature sensor (Ttl) detects seasonal temperature changes and is installed in a location that is not susceptible to temporal or instantaneous temperature changes 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 at the bottom of the house, and unlike the other 81 vents, it is easily accessible, so the shutter can be opened and closed manually, but of course it can be used like any other equipment. The operation may be automated. Further, the exhaust passage opening/closing device (1) and the underfloor ventilation hole (4) may be of any type as long as they satisfy these functions, and are not limited to those shown in this embodiment.

In the sequence diagram shown in Figure 2 (b), the power source is a DC power source that combines a solar cell and a storage battery, as shown in the circuit shown in Figure 2 (a), from the point of view of energy conservation and power outage compensation. It does not have to be a power source, but it may be a general household power source.

Since the device of the present invention operates constantly in both summer and winter, it is very effective as a power saving measure to obtain power by returning solar energy to electrical energy.
There is no need to worry about power outages, which is common with eyebrow power supplies. During the day, the solar cells supply current to each device, and excess electrical energy is stored in the storage battery. The storage battery can be used as a power source on cloudy days or after sunset! # Supply current to class.

The temperature sensor (T}[) detects when the surrounding temperature rises.
Close the a contact (TH-a) of the temperature sensor (Tlt),
Excite the relay coil (MCI) and connect the relay coil a contacts (MCI-al), (MCI-a2), (M
CI-a3) and close the b contact (MCI-a3) of the relay coil.
bl) , (MCI-b2) , (MCI-b3)
Open《. Therefore, the gear motor (IM) operates and the attic ventilation fan (2》 motor (2 old), (2M2
) is activated. When the exhaust path (5) is opened, the gear motor (IM) hits the limit switch (LS2), opens the b contact (LS2-b) of the limit switch, and stops.

Therefore, if you open the underfloor ventilation hole (4), as shown in Figure 4, cold air will enter through the underfloor ventilation hole (4)9 and warm air from the attic will be exhausted outside, reducing the indoor temperature. It's going to happen.

When the temperature around the temperature sensor (Tl{) decreases, the a contact (TH-a) of the temperature sensor (Tll) opens, the relay coil (MCI) is demagnetized, and the a contact (MCI-al) of the relay coil ( MCI-i2) , (MC
I-a3) is opened, and the relay coil b contact (MCI
-bl), (IJCI-b2), (MCI-b
3), closes. Therefore, the motor (old 2) and (2M2) of the attic ventilation fan (2) stop, the motor (3M) of the vertical duct fan (3) starts operating, and the gear motor (
IM) is activated.

The gear motor (IM) operates in the direction of closing the exhaust # (5) because the current flow is reversed this time, and when it closes, it hits the limit switch (LSI) and closes the b contact (LSI) of the limit switch. -b) and stop.

Therefore, if the underfloor ventilation hole (4) is closed, the air warmed by the heat transmitted from the south wall and roof and accumulated in the attic will descend through the hollow columnar body (7) and reach the underfloor area, as shown in Figure 5. It reaches the space (9) ζ, then rises through the wall space (10), circulates through the house, and heats each room.

Figure 3 is a sequence diagram in which the power source is an AC power source, which is a general household power source, and the operation is similar to Figure 2 (b), except that a reversible motor is used for the gear motor (lM). Therefore, the explanation will be omitted.

Effects of the Invention> As is clear from the above description, according to the present invention, in a house with an air cycle structure, the air flow in the air passage can be changed to completely different flows in accordance with the summer and winter seasons. It can be easily changed to allow smooth air flow. It also provides a comfortable living experience for the house and reduces heating and cooling costs by effectively utilizing natural energy through solar cells. In addition, since the warm air inside the air passage is constantly flowing, it is possible to suppress local moisture generation and dew condensation, and prevent wood from corroding and steel from rusting.

This has the above effects.
