DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation system for a house for ventilating a room in a house.

[0002]

2. Description of the Related Art Conventionally, in a general-purpose house, an appropriate amount of ventilation has been obtained from a space between fittings. However, in recent years, in single-family houses and condominiums such as condominiums, the airtightness of the rooms tends to be improved in order to improve the cooling and heating efficiency.

[0003] As a result of the improvement in airtightness, there has been a problem that the air permeability of each room in a house is deteriorated, and mold is easily generated due to dew condensation or the like generated on window glass and walls.

For this reason, there is an air conditioning system in which a duct is provided in each room and air is adjusted by the duct. However, this air-conditioning system is suitable for use in large-scale buildings such as buildings where one floor is substantially connected to each other, but in single-family houses and condominiums and other condominiums, individual devices must be provided. However, there is a problem that the cost increases.

For this reason, a ventilation method described in Japanese Patent Application Laid-Open No. 3-199841 has been adopted.

That is, a forced exhaust port for forcibly exhausting air is provided at the entrance of a house or an apartment. In addition, each room is provided with a natural air supply port for flowing outside air into the room and a ventilation port for flowing room air.

Then, a ventilation flow passage is formed in which the air from the natural air supply port flows into the room and the air in the room flows through the ventilation port to the forced exhaust port.

[0008]

However, in such a conventional ventilation structure, when the outside air taken in from the natural air supply port is cold at the time of heating, cold air (cold draft) is given to a person near the natural air supply port. Gives a sense of discomfort.

Also, since there is only one forced exhaust port, if the amount of forced exhaust is increased, the pressure difference between the room provided with the forced exhaust port and another room becomes large, making it difficult for the door to open and close. There was also a problem that the noise was generated depending on the amount of wind passing through the gap between the fittings.

In order to eliminate this pressure difference, it is conceivable to increase the opening area of the intake port. However, in this method, when the wind is strong, it is susceptible to the outside air, and the cold air (cold draft) is not affected. The problem grows.

Since the problem of the pressure difference can be grasped to some extent at the time of building planning, in a room far from the forced exhaust port, measures such as increasing the opening area of the ventilation hole to reduce the ventilation resistance can be taken. Depends on the position of the fittings,
In recent years, if the floor plan is changed due to a renovation or the like performed, it cannot be handled.

Moreover, the required ventilation volume in each room differs depending on the presence or absence of a person and the presence or absence of indoor pollutants (water vapor, smoke, carbon monoxide, etc.). It is not possible to control the amount of ventilation for each, and a room that does not need ventilation is uniquely ventilated. For this reason,
As the cooling / heating efficiency decreases, the amount of electric power for operating the forced exhaust port increases. In addition, exhaust noise is loud,
There was also a problem that hindered sleep at night.

[0013] Therefore, the present invention, regardless of the outside air condition,
A house that can comfortably introduce outside air, reduce the pressure difference between each room, provide necessary ventilation for each room, and reduce construction and running costs and reduce noise. It is an object to provide a ventilation system for use.

[0014]

According to a first aspect of the present invention, an air conditioner having a forced outside air intake function is provided at an outside air intake of each room of a house. A forced exhaust ventilation fan, which is provided at a ventilation opening communicating between the inside and outside of the house and forcibly exhausting the air of each room to the outside of the house through the ventilation opening, while forming a ventilation opening for ventilating between the rooms. a residential ventilation system provided, each
Based on the required ventilation volume of the room, the air conditioner is
Determining the amount of outside air to be input, and having a control means for exhausting amount and substantially the same for exhausting exhausting the outside air amount of the sum to be introduced into the room by the air conditioner by the forced draft ventilators housing For ventilation system.

According to a second aspect of the present invention, the control means includes a contaminated atmosphere sensor in each of the rooms,
The present invention is characterized by a residential ventilation system that detects a polluted atmosphere with the polluted atmosphere sensor and controls the air conditioner of each room to operate.

[0016]

According to the first aspect of the present invention, the control means is configured to exhaust the outside air introduced into the room by the air conditioner provided in each room by the forced exhaust ventilation fan. And it is almost the same.

For this reason, the pressure difference between the rooms can be eliminated.

Also, since the outside air is introduced after the temperature, humidity, air volume and the like are adjusted by the air conditioner provided in each room, each room is provided with a comfortable atmosphere regardless of the state of the outside air. Can be done.

In addition, since the forced exhaust ventilation fan only needs to exhaust the amount of outside air introduced into the room, the operation amount of the forced exhaust ventilation fan can be varied as necessary, thereby reducing running costs and reducing noise. Can be reduced.

According to the second aspect of the present invention, the control means detects the polluted atmosphere with each of the polluted atmosphere sensors provided in each of the rooms, and activates each of the air conditioners in each of the rooms. To control.

For this reason, only the room in which the contamination has occurred is ventilated, so that the cooling and heating efficiency is good and the exhaust air volume of the forced exhaust ventilation fan is only the amount required for the room having the contaminated atmosphere. Further, the running cost can be suppressed and the noise can be reduced.

In the drawing, reference numeral 1 denotes a household of an apartment which is an apartment house to which the ventilation system for a house is applied, and the household 1 includes a corridor 3 extending from an entrance 2. As the center, Western-style rooms 4, 5 and Japanese-style room 6, dining room 7, kitchen 8, sanitary 9,
They are distributed and arranged on one floor.

The sanitary 9 mainly comprises a toilet 10, a bathroom 11, and a dressing room 12.

The outside air intakes 14 to 17 of the rooms 4 to 7
Are provided with air conditioners 18 to 21 having a forced outside air intake function.

The air conditioners 18 to 21 take in outside air or indoor air by switching, perform air conditioning for cooling in summer and heating in winter, and supply the air to the rooms 4 to 7.

In each of the rooms 4 to 7, contaminated atmosphere sensors 22 to 25 are provided on the ceiling, respectively.

The contaminated atmosphere sensors 22 to 25 detect the contaminated atmosphere (water vapor, smoke, carbon monoxide, etc.) in each of the rooms 4 to 7, and when the detected atmosphere exceeds a certain value, it is judged that the air is contaminated. And the air conditioners 18 to 21 in the rooms 4 to 7
Is operated.

Between the rooms 4 to 7 and the corridor 3, vents 26 to 29 are formed for ventilating between the rooms. Each of the vents 26 to 29 is configured such that a plurality of blades are attached to a square frame, and the opening degree can be adjusted by rotating the blades around the mounting axis of the blades.

Further, on the outer wall of the kitchen 8 continuous with the dining room 7, a ventilation opening 3 communicating the inside and outside of the house is provided.
0 is provided. The ventilation port 30 is provided with a forced exhaust ventilation fan 31 for forcibly exhausting the air in each of the rooms 4 to 7 to the outside of the house through the ventilation ports 26 to 29. At the periphery of the forced exhaust ventilation fan 31, a range hood 32 for rectifying the outflow airflow is provided.

The forced exhaust ventilation fan 31 has a displacement of 0
From about 300 that can fully ventilate all rooms 4-7
It is configured so that it can be driven steplessly up to cubic m / h.

A control box 33 is provided as control means for controlling the amount of outside air introduced into each of the chambers 4 to 7 by the air conditioners 18 to 21 to be substantially the same as the amount of exhaust air exhausted by the ventilation fan 31 for forced exhaust. are doing.

The control box 33 is disposed at a predetermined location in the room, and is electrically connected to the respective polluting atmosphere sensors 22 to 25 as shown in FIG. The ventilation fan 31 for forced exhaust is also electrically connected to each other to control the amount of ventilation.

Next, the operation of the first embodiment will be described.

In the residential ventilation system according to the first embodiment, as shown in FIG.

Based on the required ventilation, each room 4-7
The intake air amount to be introduced from outside is introduced by the air conditioners 18 to 21. Therefore, each of the air conditioners 18 to 21 controls the outside air whose temperature, humidity, and the like are appropriately adjusted based on the determined intake outside air amount from the outside air inlets 14 to 17 to each room 4.
~ 7.

In the control box 33, the air conditioners 18 to 21 provided in the rooms 4 to 7 are used to control the rooms 4 to 4.
7. Calculate the sum by summing up the amount of outside air introduced into 7,
The amount of air exhausted by the forced exhaust ventilation fan 31 is:
The displacement of the forced exhaust ventilation fan 31 is calculated so as to be substantially the same as the sum.

On the basis of the calculation of the displacement of the forced exhaust ventilation fan 31, the forced exhaust ventilation fan 31 is steplessly variably driven to discharge the polluted air.

Therefore, it is possible to eliminate the pressure difference between the rooms 4 to 7. Therefore, there is no possibility that resistance will be caused in opening and closing the doors of the rooms 4 to 7.

The air conditioner 1 provided in each of the rooms 4 to 7
Since the outside air is introduced after adjusting the temperature, humidity, air volume and the like by 8 to 21, it is possible to make each room 4 to 7 a comfortable atmosphere state regardless of the state of the outside air. Therefore, the introduction of cold air (cold draft), which has been a problem in the past, is also eliminated.

In addition, necessary ventilation can be performed in each of the rooms 4 to 7, and the operation amount of the forced exhaust ventilation fan 31 can be reduced to a necessary amount, so that running costs can be suppressed and noise can be reduced.

Then, the forced exhaust ventilation fan 31 is connected to each room 4.
Since it is not necessary to arrange every 7 to 7, the construction cost can be suppressed.

The control box 33 is connected to each of the rooms 4.
7 are detected by polluting atmosphere sensors 22 to 25 provided for each of the air conditioners 18 to 17 of the respective rooms 4 to 7.
21 are controlled to operate.

For this reason, only the contaminated rooms 4 to 7 are ventilated, so that the cooling and heating efficiency is good and
Since the exhaust air volume of the forced exhaust ventilation fan 31 may be only the amount required for the rooms 4 to 7 having the polluted atmosphere, the running cost can be further reduced and the noise can be reduced.

For example, at the time of a dinner where only the dining room 7 has a person, when ventilation is constantly performed, about 150
Although a cubic m / h of ventilation was required, in this embodiment, the amount of exhaust air from the forced exhaust ventilation fan 31 is reduced by suppressing the introduction of outside air into the Western rooms 4, 5 and the Japanese room 6 where there are no people. It can be completed at 75 cubic m / h.

At night, the amount of contaminants generated in each of the rooms 4 to 7 is small, so that the ventilation is automatically reduced and noise is eliminated, so that sleep can be ensured.

FIG. 4 shows a second embodiment, in which a detached house 3 is shown.

[0055]

As described above, according to the first aspect of the present invention, the control means controls the amount of outside air introduced into the room by the air conditioner provided in each room. The amount of air exhausted by the exhaust ventilation fan is almost the same.

Therefore, it is possible to eliminate the pressure difference between the rooms. Therefore, there is no fear that resistance will be caused in opening and closing the doors of each room.

Further, since the outside air is introduced after the temperature, humidity, air volume and the like are adjusted by the air conditioner provided in each room, each room can be set in a comfortable atmosphere regardless of the state of the outside air. Can be done. Therefore, the introduction of cold air (cold draft), which has been a problem in the past, is also eliminated.

In addition, necessary ventilation can be performed in each room, and the operation amount of the forced exhaust ventilation fan can be reduced to a necessary amount, so that running costs can be suppressed and noise can be reduced.

Since it is not necessary to provide a forced exhaust ventilation fan for each room, the construction cost can be reduced.

According to the second aspect of the present invention, the control means detects a polluted atmosphere with a polluted atmosphere sensor provided in each of the rooms and controls the air conditioner in each of the rooms to operate. .

[0061] Therefore, only the room where the contamination occurs is ventilated, so that the cooling and heating efficiency is good and the exhaust air volume of the forced exhaust ventilation fan is only the amount required for the room having the contamination atmosphere. Further, the present invention exerts a practically useful effect of suppressing running costs and reducing noise.
