  The outside air cleaning unit 31 has an air purifier (not shown) such as a filter, cleans the outside air introduced through the heat insulation duct 36, and supplies it as the outside air after cleaning. Since the house air cleaning device 30 has a substantially sealed structure with the housing 30a, when the air supply ventilator 32 is operated, the inside of the housing 30a becomes negative pressure. For this reason, the outside air cleaning part 31 in the housing 30a cleans the introduced outside air and naturally supplies the outside. In addition, the air volume adjusting device 35 is attached to the housing 30a, and the air volume adjusting device 35 adjusts the indoor air introduction amount into the housing 30a.

A non-insulated duct 37 that communicates with an air supply port 34 that opens in the play space 21 (ceiling pocket) of the house is attached to the air supply ventilation device 32 of the house air cleaning device 30. The air supply ventilator 32 converts the inside / outside mixed air (mixed air between the clean outside air supplied from the outside air cleaning unit 31 and the indoor air introduced through the air volume adjusting device 35) in the housing 30a into the non-insulated duct 37. Air is blown through the play space 21 (ceiling pocket) of the house. An air conditioner 38 may be installed in the housing 30a of the house air cleaning device 30.
The house air purifier 30 cleans the outside air from outside the house 1 and cleans it, and blows air that has been cleaned and adjusted in temperature and humidity into the play space 21 (ceiling pocket) of the house. As a result, air that has been cleaned and adjusted in temperature and humidity by the house air purifier 30 is sent out to the play space 21 (ceiling pocket) of the house.

  The house air purifier 30 has an air supply ventilator 32 composed of a blower motor as power. When the air flow rate of the air supply ventilation device 32 is set to Out and the air flow rate of the air flow rate adjusting device 35 is set to In1, the outside air cleaning unit 31 of the house air cleaning device 30 is set to have the air flow rate In2 = Out-In1.

Air is blown into the space 20). The amount of air blown through the indoor air supply port is controlled by a plurality of air volume adjusting devices 41. Further, the amount of exhaust to the outdoors is controlled by the exhaust ventilation device 40 and the exhaust air volume adjustment device 42. As described above, the air volume adjusting devices 35, 41, and 42 include an active device using a motor and a passive device using a damper, both of which can be used.

FIG. 4 is a diagram for explaining a ventilation plan of the house 1 including the house air purifier 30. FIG. 4 (a) shows a room layout on the first floor, and FIG. 4 (b) shows a room on the second floor. Show the percentage.
As shown in FIG. 4 (a), the first floor includes a hall, hallway, entrance, LDK, kitchen, western-style room 1, washroom, bathroom, toilet, and staircase.
As shown in FIG. 4B, the second floor includes a corridor / free space, a master bedroom, a Western-style room 2, a Western-style room 3, a walk-in closet, and a toilet.
The LDK, kitchen, western-style room 1, washroom, restroom, toilet, main bedroom, and corridor / free space rooms are provided with exhaust ports 131 to 137, and the exhaust ports 131 to 137 are connected via ducts (not shown). To the house air cleaning device 30 (see FIG. 1). In addition, it can also exhaust to the outdoors directly from some exhaust ports 131-137.
The allocation of the residential space by the room allocation is a general one.

Hereinafter, an effect | action of the house 1 provided with the air cleaner 30 for houses comprised as mentioned above is demonstrated.
As shown in FIG. 1, the house 1 has a highly airtight and highly heat-insulating structure, a house space 20, a play space 21 of the house formed in the ceiling pocket, and a play space 22 of the house formed in the gap between the outer and inner walls. And a house air purifier 30 that cleans the outside air and adjusts the temperature and humidity to supply air to the play space 21 (ceiling pocket) of the house. The play spaces 21 and 22 of the house exist in many houses.

As indicated by the white arrow “a” in FIG. 1, the house air purifier 30 supplies (blows) the adjusted air (cleaned outside air) to the play space 21 (ceiling pocket) of the house. In the example of FIG. 1, the house air purifier 30 supplies the adjusted air toward the upper part of the play space 21 (ceiling pocket) of the house on the left side of the ceiling back 15a. The air supplied to the play space 21 (ceiling pocket) of the house flows in all directions in the play space 21 (ceiling pocket) of the house on the ceiling 15a, as indicated by the white arrow a in FIG.
The air supplied to the play space 21 (ceiling pocket) of the house is supplied to each room of the residence space 20 through the air flow paths (1) and (2) described below.

<Air channel (1)>
As shown in FIG. 1, the play space 21 (ceiling pocket) of the house on the ceiling back 15 a communicates with the play space 22 (gap between the outer and inner walls) of the house between the outer wall 12 and the inner wall 13. For this reason, the air supplied to the play space 21 (ceiling pocket) of the house extends along the outer wall 12 and the inner wall 13 from the play space 21 (ceiling pocket) of the house, as indicated by the white arrow b in FIG. It flows into the play space 22 of the house (the gap between the outer and inner walls). The air flowing from the play space 21 (ceiling pocket) of the house into the play space 22 (gap between the outer and inner walls) of the house is not limited to the play space 22 (gap between the outer and inner walls) on the left side of FIG. In the play space 22 of the right house (gap between the outer and inner walls) and the play space (not shown) of the house in the front-rear direction in FIG.

  Here, since the house 1 is a highly airtight and highly heat-insulated residence, it is difficult to receive a reduction in the air volume due to air leakage or the like and an outdoor temperature environment. In particular, a play space 21 (ceiling back space) of a house defined between the ceiling 15 of the living space 20 and a house defined between the outer wall 12 and the inner wall 13 which is a side wall of the living space 20 are shown. The play space 22 (the space between the outer and inner walls) is kept highly airtight and communicates with each other, and there is very little air leakage. For this reason, the air conditioned by the house air purifier 30 flows through the play space 22 (gap between the outer and inner walls) of the house to the bottom of the floor 14 below the housing space 20 with a stable air volume (see FIG. 1 (see white arrow c).

<Air channel (2)>
On the other hand, a part of the air supplied to the play space 21 (ceiling pocket) of the house flows in the right direction (center direction) on the ceiling 15a as indicated by the white arrow d in FIG.
The air supplied toward the center of the play space 21 (ceiling pocket) of the house is supplied into the residential space 20 from a plurality of air volume adjusting devices 41 installed at the outside air inlet (ceiling grill) of the ceiling 15. (See the white arrow e in FIG. 1). The amount of air blown at the indoor air inlet is controlled by a plurality of air volume adjusting devices 41. Thereby, in the residential space 20, air that has been cleaned and adjusted in temperature and humidity is supplied from a plurality of air volume adjustment devices 41 (ceiling grills) (see white arrows f in FIG. 1).
Further, as indicated by the white arrow g in FIG. 1, the exhaust ventilation device 40 collects the air in the residential space 20 from the exhaust air volume adjustment device 42 and exhausts it outdoors via the duct 44 (FIG. 1). (See white arrow h). The amount of air exhausted outdoors can also be controlled by the air volume adjusting device 42 for exhaust.

  By the way, the house 1 is a highly airtight and highly insulated house, and the play space 21 (ceiling back space) of the house and the outer wall 12 and the play space 22 of the house (space between the outer and inner walls) are kept highly airtight, respectively. Leaked and communicated, there is very little leakage from the play spaces 21 and 22 of the house to the outside. Therefore, the amount of outside air supplied by the house air purifier 30 to the play space 21 of the house can be adjusted by the plurality of air volume adjustment devices 41 installed at the outside air inlet (ceiling grill) of the ceiling 15. .

  Thus, the house 1 provided with the house air purifier 30 blows the air, which has been cleaned by the house air cleaner 30 and adjusted in temperature and humidity, to the play space 21 (ceiling pocket) of the house on the ceiling 15a. Then, the clean air in the play space 21 (ceiling pocket) of this house is distributed along the wall through the play space 22 (gap between the outer and inner walls) communicating with the play space 21 (ceiling pocket) of the house. Let The air circulated through the play spaces 21 and 22 of the house is supplied to the residential space 20 from a plurality of air volume adjustment devices 41, walls, floors, and the like.

  As described above, the house 1 includes the play space 21 (ceiling space) of the house defined between the roof 11 and the ceiling 15 of the living space 20, and the inner wall that is the side wall of the outer wall 12 and the living space 20. 13 is a house air purification device that cleans the indoor play space 22 (space between the outer and inner walls) that is defined between the house 13 and the indoor play space 21, and the indoor air that defines the outside air or the living space 20. 30, and the house air purifier 30 supplies purified air to the play space 21 (ceiling space) of the house, and flows the air flowing along with the supply air into the play space 22 ( Distribute to the space between the outer and inner walls.

As described above, the house 1 including the house air purifier 30 uses the play space (back of the ceiling, between the outer wall and the inner wall) of the house as a passage (duct) for air circulation (clean air blowing). In other words, the play spaces 21 and 22 of the house are used for the air supply passage for supplying the purified air to each room, and the exhaust ducts 131 to 137 for collecting the air from each room are provided with exhaust ducts. use. For this reason, supply air and exhaust air are not mixed.
In particular, the house 1 including the house air cleaning device 30 can significantly reduce costs (duct materials and construction costs) because there is no air supply duct. In addition, by using an exhaust duct, it is also possible to blow air more efficiently for each floor or the like.

  Further, since there is no need to route the duct from the house air cleaning device 30 to the residential space 20, there is an effect that a special design method and construction are not required so that the air supply duct is not visible. Further, if the duct for supplying air is routed around the ceiling or wall, the thickness of the ceiling or wall increases by the amount of the duct diameter, and the living space such as the living room or kitchen, or the office room tends to be narrowed. In this embodiment, since a duct for supplying air is unnecessary, it is possible to suppress the narrowing of the residential space without increasing the thickness of the wall or the like.

  Further, since the play spaces 21 and 22 of the house exist in many houses, it is not necessary to use a special design or construction method. Since existing house design methods and construction methods can be applied as they are, design and construction can be simplified.

  In the present embodiment, the house air purifier 30 is provided with a filter and an air purifier in the outside air purifying unit 31 to eliminate anxiety about indoor pollution caused by intake air (for example, the influence on human body due to PM2.5 or standby pollutants). Mitigation).

  In the present embodiment, the outside air to be introduced is not directly blown into each room, but is temporarily put into the house air purifier 30, and the house air purifier 30 circulates a part of the room air. Thereby, introduction outside air and room air can be mixed and heated, and the same effect as a heat exchanger can be acquired.

  Further, the house air purifier 30 can also adjust the temperature and humidity by installing an air conditioner 38. It is possible to reduce the indoor temperature and humidity environment and the user's discomfort (such as a cold wind feeling and a feeling of bullying). In addition, by installing the air conditioner 38, there is no fear of contamination of the heat exchange element used in the heat exchange type ventilation device, and maintenance is unnecessary.

  Moreover, in this embodiment, since the several air volume adjustment apparatus 41 is installed facing the residence space 20, it is possible to adjust and set the external air introduction amount to each room. For example, as shown in FIG. 1, the air volume can be set by installing a plurality of air volume adjusting devices 41 at the outside air inlet (ceiling grill) of the ceiling 15. Since the necessary air volume can be set, an appropriate air environment can be realized. Further, the ratio between the outside air introduction amount and the indoor air recirculation amount can be set.

Here, if the structure of the house 1 is not highly airtight and highly heat-insulating, a stable air volume cannot be ensured due to air leakage or the like, and it is easy to receive an outdoor temperature environment.
Moreover, since the air cleaner 30 for houses does not affect another room by introduction | transduction outside air, it is desirable to perform an airtight heat insulation process independently.

The above description is an illustration of a preferred embodiment of the present invention, and the scope of the present invention is not limited to this.
For example, as an example of a highly airtight and highly heat-insulating structure, there is a house constructed by another construction method such as two-by-four.
