Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a house ventilation system.

[0002]

2. Description of the Related Art Conventionally, as a house ventilation system for ventilating an entire house, for example, as described in JP-A-63-165632, an air intake is provided in a space under the floor, and a space from the space under the floor to the space behind the hut is provided. There is known a ventilation system for a house in which communication is provided in an air shaft zone, an air exhaust port is provided in the space behind the cabin, and an air intake port and an air exhaust port are provided above and below each living room. I have. In this ventilation system for a house, the air in the entire house is ventilated by air flowing from the underfloor space to the back of the cabin due to the rising force of the air generated by the temperature difference and the wind pressure generated by the wind.

[0003]

However, in the house ventilation system described in Japanese Patent Application Laid-Open No. 63-165632, since the temperature difference between the inside and outside of the house and the wind speed are greatly affected, a stable and constant ventilation rate is obtained. Is difficult to secure. For example, when the temperature drops, the lower floor is heated or the difference between the temperature of the upper floor room and the temperature of the lower floor room increases due to heat reflected from the ground. For this reason, there is a problem that the ventilation volume on the lower floor is increased and the room on the upper floor is hardly ventilated. In addition, various fittings such as sliding doors and hinged doors are used for ordinary living room fittings.
The gap varies depending on the type of the door. Therefore, there is a problem that the air resistance at the time of ventilation varies depending on the size of the gap, and that the ventilation of each living room is not performed evenly.

Further, fittings with large gaps such as sliding doors and double doors are often used on the lower floors, and fittings with small gaps such as panel doors are often used on the upper floors. However, if the gap on the upper floor is small, there is a problem that the ventilation volume is increased only on the lower floor, and the room on the upper floor is hardly ventilated. An object of the present invention is to solve these problems and to provide a house ventilation system capable of performing well-balanced ventilation of each room on the upper floor and the lower floor while responding to climatic conditions throughout the four seasons.

[0005]

According to a first aspect of the present invention, there is provided a house ventilation system according to the first aspect of the present invention, wherein a ventilation opening provided in each of the upper floor and lower floor living rooms, and the upper floor and lower floor living rooms are provided. And a partition or fitting provided between the hall and the stairwell, a through-hole provided in the partition or fitting, and a ventilation fan for exhaust provided to the outside wall or ceiling of the hall and connected to the outside, An air supply fan is attached to the ventilation port of the car, and the air supply fan automatically operates when the temperature of the outside air falls below a predetermined temperature, and stops automatically when the temperature of the outside air exceeds the predetermined temperature And

According to a second aspect of the present invention, there is provided a house ventilation system according to the present invention, wherein a ventilation opening provided in each of the upper floor and lower floor living rooms, and an upper floor and lower floor living room and an atrium are provided. A partition or fitting provided between the partition and the fitting, a through-hole provided in the partition or fitting, and a ventilation fan for exhaust provided to the outside of the hall or on the ceiling provided to the outside, the upper floor partition or An electromagnetic shutter is provided in the through hole provided in the fitting, and when the temperature of the outside air exceeds a predetermined temperature, the electromagnetic shutter automatically closes and the ventilation area of the through hole is provided in the lower floor partition or the fitting. The electromagnetic shutter is automatically opened when the temperature falls below a predetermined temperature, and the ventilation area of the through-hole becomes larger than the through-hole provided in the partition or the fitting on the lower floor. .

The predetermined temperature in the first and second aspects of the present invention is a preset temperature,
It can be set arbitrarily. For example, the predetermined temperature may be 0 ° C., 5 ° C., or −5 ° C.

(Effect) In the house ventilation system according to the first and second aspects of the present invention, a ventilation opening provided in each of the upper floor and lower floor living rooms and communicating with the outside,
A partition or fitting provided between each living room on the lower floor and the hall of the atrium, a through-hole provided in the partition or fitting, and a ventilation fan for the exhaust provided to the outside provided on the outer wall or ceiling of the hall; Therefore, when the ventilation fan is operated, the outdoor air sucked from the ventilation port of each living room is forcibly exhausted from the through hole provided in the partition or the fitting through the hole.

When the temperature of the lower floor is significantly higher than the temperature of the upper floor due to the heating on the lower floor or the heat reflected from the ground in winter or the like, the air on the lower floor rises quickly in the hall and the lower floor rises. Although the ventilation volume of the room on the floor is increased, the air flow on the upper floor is obstructed, and the exhaust on the upper floor is not sufficiently performed. The temperature of the upper floor is significantly higher than the temperature of the lower floor, for example, 0, because the air supply fan is automatically operated when the temperature of the outside air falls below a predetermined temperature. If the temperature of ° C. is set to a predetermined temperature in advance, the air supply fan operates automatically and the intake volume on the upper floor increases,
The increase in ventilation on the lower floor due to the temperature difference is offset, and the ventilation on the upper floor and the lower floor is almost the same, and the ventilation on the upper floor does not become insufficient. Conversely, when the temperature of the lower floor becomes equal to or higher than a predetermined temperature at which the temperature of the lower floor does not become significantly higher than the temperature of the upper floor, the air supply fan is automatically stopped, so that the upper floor and the lower floor are ventilated in substantially the same manner. Thus, at any temperature,
The air ventilation of the upper floor room and the lower floor room is well-balanced,
Well done.

According to the second aspect of the present invention, when the temperature of the outside air falls below a predetermined temperature, the electromagnetic shutter is automatically opened, and the upper floor partition or the ventilation area of the through hole provided in the fitting has the lower floor partition. Or, because it is larger than the through-hole provided in the fittings, the resistance of the air flowing out to the atrium through the through-hole on the upper floor is reduced, and the ventilation on the lower floor is increased due to the temperature difference. As a result, the ventilation on the upper floor and the lower floor are almost the same, and the ventilation on the upper floor is not insufficient. Conversely, if the temperature of the outside air rises above a predetermined temperature at which the temperature does not increase significantly compared to the temperature of the upper floor, the electromagnetic shutter automatically closes and the ventilation area of the through-hole provided in the partition or the fitting on the upper floor becomes lower. Since it becomes substantially equal to the through hole provided in the partition or the fitting, the upper floor and the lower floor are ventilated in substantially the same manner. Thus, at any temperature, the ventilation of the air in the upper floor room and the lower floor room is well balanced, and
Well done.

As described above, according to the first aspect of the present invention,
Also in the second aspect of the invention, even if the temperature of the outside air rises or falls, the ventilation of the air in the room on the upper floor and the room on the lower floor are well balanced and sufficiently performed. In addition, since the operation / stop of the air supply fan and the opening / closing of the electromagnetic shutter are all performed automatically, the operation / stop of the air supply fan and the opening / closing of the electromagnetic shutter are not forgotten, and therefore, reliably and efficiently. Done.

Embodiments of the present invention will be described below with reference to the drawings. (Embodiment 1) First, the embodiment shown in FIGS. 1 and 2 will be described. 1 and 2 show an embodiment of a house ventilation system according to the present invention. FIG. 1 is a sectional view of a house, and FIG.
(A) is an explanatory view showing an upper floor ventilation port, and (B) is an explanatory view showing a lower floor ventilation port.

In FIG. 1 and FIG. 2, A is a house, and this house A has rooms 11 and 12 on the lower floor and room 2 on the upper floor.
1 and 22 are provided, and between the living rooms 11 and 21 and the living rooms 12 and 22, there is provided an atrium 31 having a through-hole from the lower floor to the upper floor. A ventilation fan 32 is provided on the ceiling of the hall 31 so as to communicate with the back of the hut 33. There are gaps 33a, 3
3b is provided.

The lower floor rooms 11, 12 and the upper floor rooms 2
Partitions 41, 42, 43, 44 are provided between the holes 1, 22 and the atrium 31.
1, 42, 43 and 44 have through holes 11a and 12 respectively.
a, 21a and 22a are provided. In addition, ventilation holes 11b, 12b, 21b, 22b communicating with the outside are provided on the outer walls of the lower-floor rooms 11, 12 and the upper-floor rooms 21, 22. The ventilation fan 32 can be operated or stopped by a switch (not shown).

Further, a ventilation port 11b provided on the outer wall,
As shown in FIGS. 2A and 2B, 12b, 21b, and 22b have waterproof hoods 20 attached to their upper edges and open downward. A louver 30 is provided in this opening. An air supply fan 5 is provided in the ventilation holes 21b and 22b on the upper floor.
Is attached. A temperature sensor 6 is mounted on the outdoor side, and the temperature sensor 6 constantly measures the temperature of the outside air. When the temperature falls below a predetermined temperature, the temperature sensor 6 detects the temperature and activates the air supply fan 5, and when the temperature sensor exceeds the predetermined temperature, the air supply fan 5 is stopped.

The ventilation method of the house ventilation system will be described. First, a switch (not shown) is turned on, and the ventilation fan 32 in the hall 31 is operated. Then, the air in the hall is forcibly lifted upward and is discharged from the hall 31 to the outside air through the hut back 33, as a result, as shown by the arrow in FIG. 1, the air is passed through the ventilation opening → the living room → the partition. →
Ventilation is performed in the order of hall → ventilation fan → hut back → gap → outdoor. Thus, the ventilation is forcibly performed, and the ventilation openings 21b and 22b on the upper floor and the ventilation openings 11b and 12 on the lower floor are provided.
b has substantially the same ventilation area, so that substantially the same amount of air enters through these ventilation ports 11b, 12b, 21b, 22b, and therefore the air ventilation is well-balanced, and
Well done.

In this state, the temperature of the lower floor is significantly higher than the temperature of the upper floor in winter or the like, and the air on the lower floor rises quickly in the hall, and the ventilation volume of the room on the lower floor is increased. Although the air flow on the floor is obstructed and exhaust on the upper floor is not performed sufficiently, the predetermined temperature is set in advance to a temperature (for example, 0 ° C.) at which the temperature of the upper floor is significantly higher than the temperature of the lower floor. If the temperature of the outside air becomes equal to or lower than the predetermined temperature (0 ° C.), the air supply fan 5 automatically operates to increase the intake air volume of the upper floors 21b and 22b, and the lower floor ventilation due to the temperature difference. The increased volume is offset by substantially the same ventilation.

When the temperature of the lower floor becomes equal to or higher than a predetermined temperature at which the temperature of the lower floor does not become significantly higher than the temperature of the upper floor, the air supply fan 5 is automatically stopped. Is done. As described above, at any temperature, the ventilation of the air in the room on the upper floor and the room on the lower floor are well balanced and sufficiently performed. Further, since the operation and stop of the air supply fan 5 are automatically performed, the air supply fan 5 is operated only when necessary, and the operation and stop of the air supply fan 5 are not forgotten.

(Embodiment 2) Next, Embodiment 2 shown in FIGS. 3 and 4 will be described. FIG. 3 is a front view of a through hole provided in a partition wall on the upper floor, FIG. 4A is an explanatory diagram showing a through hole on the upper floor in a state where the electromagnetic shutter is closed, and FIG. It is explanatory drawing which shows the through hole of the upper floor of a state.

The second embodiment shown in FIGS. 3 and 4 is different from the first embodiment shown in FIG. 1 in that an air supply fan is not provided in a ventilation hole provided in an outer wall, but is provided in a partition wall on an upper floor. The difference is that an electromagnetic shutter is provided in the through hole provided. Therefore, the structure of the through-hole provided in the upper floor partition will be described. The same components as those shown in the first embodiment will be described with the same reference numerals. In the embodiment shown in FIGS. 3 and 4, the electromagnetic shutter 7 is attached to the through holes 21a and 22a provided in the upper floor partition.

A temperature sensor (not shown) is mounted on the outdoor side, and the temperature sensor constantly measures the temperature of the outside air. When the temperature falls below a predetermined temperature, the temperature sensor detects the temperature and closes the electromagnetic shutter 7 as shown in FIG. When the temperature of the temperature sensor becomes equal to or higher than a predetermined temperature, the electromagnetic shutter 7 is opened as shown in FIG. In addition, the electromagnetic shutter is not provided in the through holes 11a and 12a provided in the partition on the lower floor. And, when the electromagnetic shutter 7 is closed, the through-holes 21a and 22a provided in the upper floor partition have the through-holes 11a and 22a provided in the lower floor partition when the electromagnetic shutter 7 is closed. 1
2a, so that when the electromagnetic shutter is opened, the ventilation area of the through holes 21a, 22a on the upper floor is larger than the through holes 11a, 12a provided in the partition on the lower floor. In addition, as shown in FIGS. 3 and 4 (a) and (b), a slidable door 35 is provided in the ventilation opening.

Next, the use state of the second embodiment will be described. First, a switch (not shown) is turned on, and the hole 31 is turned on.
Is operated. Then, the air in the hall is forcibly lifted upward, and the hall 31 is sunk from the hall 31.
Is released to the outside air through
The air is ventilated in the order of ventilator → living room → partition hole → hall → ventilation fan → back of hut → gap → outdoor.

Then, the temperature of the lower floor such as in winter becomes significantly higher than the temperature of the upper floor, the air of the lower floor rises quickly in the hall, the ventilation volume of the upper floor increases, and the air of the upper floor increases. Although the flow is hindered and the upper floor exhaust is not sufficiently performed, if the predetermined temperature is set in advance to a temperature (for example, 0 ° C.) in which the temperature of the lower floor is significantly higher than the temperature of the upper floor, When the temperature of the outside air falls below a predetermined temperature (0 ° C.), the electromagnetic shutter 7 automatically opens to open a through hole 21a provided in a partition on the upper floor.
Since the ventilation area of 22a is larger than the through holes 11a and 12a provided in the lower floor partition, the resistance to the atrium of the upper floor is reduced, and the ventilation rate of the lower floor is increased by the temperature difference. This cancels out that the ventilation volume on the upper floor and the lower floor are almost the same, and the ventilation on the upper floor does not become insufficient. On the other hand, when the temperature of the lower floor reaches a predetermined temperature at which the temperature of the lower floor does not become significantly higher than the temperature of the upper floor, the electromagnetic shutter 7 automatically closes and the through hole 2 provided in the partition of the upper floor.
Since the ventilation areas of 1a and 22a are almost the same as the through holes 11a and 12a provided in the partition of the lower floor, the upper floor and the lower floor are ventilated in substantially the same manner.

As described above, at any temperature, the ventilation of the air in the room on the upper floor and the room on the lower floor are well-balanced and sufficiently performed. Also, the opening and closing of the electromagnetic shutter 7 is automatically performed,
Since the electromagnetic shutter 7 operates only when necessary, there is little energy loss.

In the house ventilation system according to the first and second aspects of the present invention, a ventilation opening provided in each of the upper floor and lower floor living rooms, and the upper and lower floors are provided. It is composed of a partition or fitting provided between each living room and the hall of the atrium, a through hole provided in the partition or fitting, and a ventilation fan for exhaust provided to the outside provided on the outer wall or ceiling of the hall. When the ventilation fan is operated, the outdoor air sucked from the ventilation opening of each living room is forcibly exhausted through through holes and holes provided in the partition or the fitting.

According to the first aspect of the present invention, an air supply fan is attached to the ventilation opening on the upper floor, and the air supply fan automatically operates when the temperature of the outside air falls below a predetermined temperature. Therefore, if the temperature of the lower floor becomes significantly higher than the temperature of the upper floor, for example, a temperature of 0 ° C. is set in advance to a predetermined temperature, the air supply fan automatically operates and the upper floor becomes higher. The increase in air intake volume and the increase in ventilation volume on the lower floor due to the temperature difference are offset, so that the ventilation volume on the upper floor and the lower floor are almost the same, and the ventilation on the upper floor does not become insufficient . Conversely, when the temperature of the lower floor becomes equal to or higher than a predetermined temperature at which the temperature of the lower floor does not become significantly higher than the temperature of the upper floor, the air supply fan is automatically stopped, so that the upper floor and the lower floor are ventilated in substantially the same manner. As described above, at any temperature, the ventilation of the air in the room on the upper floor and the room on the lower floor are well balanced and sufficiently performed.

According to the second aspect of the present invention, when the temperature of the outside air falls below a predetermined temperature, the electromagnetic shutter is automatically opened to increase the ventilation area of the through hole provided in the upper floor partition. The decrease in the resistance to the hall and the increase in ventilation on the lower floor due to the temperature difference are offset, and the ventilation on the upper floor does not become insufficient. Conversely, when the temperature of the lower floor rises above a predetermined temperature that does not become significantly higher than the temperature of the upper floor, the electromagnetic shutter automatically closes and the through hole provided in the upper floor partition is provided in the lower floor partition. Since the ventilation area is substantially the same as the through hole provided, the upper floor and the lower floor are ventilated in substantially the same manner. In this way, at any temperature, the ventilation of the air in the room on the upper floor and the room on the lower floor are well balanced and sufficiently performed. Thus, according to the invention described in claim 1 and the invention described in claim 2, even if the temperature of the outside air rises or falls, the ventilation of the air in the room on the upper floor and the room on the lower floor are well-balanced, Well done.

Further, since the operation and stop of the air supply fan and the opening and closing of the electromagnetic shutter in the inventions according to the first and second aspects are all performed automatically, the operation of the air supply fan and the opening and closing of the electromagnetic shutter are forgotten. Without, therefore,
Since it is performed reliably and efficiently, there is little energy loss and it is very convenient.
