BACKGROUND OF THE INVENTION
The present invention relates to a residential ventilation system, and more particularly to a residential ventilation system that achieves maintenance and purification of a residential environment by supplying purified air to the house.
[0002]
[Prior art]
In recent years, the development of high airtightness of houses has led to the improvement of the cooling and heating efficiency, but also the problem of deterioration of the environment in the house due to insufficient ventilation.
Due to the deterioration of the residential environment, sick house syndrome, which develops mainly due to chemical substances contained in wallpaper, plywood adhesive, etc., has become a problem. Therefore, various methods using adsorption characteristics such as charcoal have been proposed in order to remove volatile chemical substances that are the causative substance of sick house syndrome (for example, Patent Document 1 or Patent Document 2).
[0003]
In Patent Document 1, for example, 1) a charcoal sheet is pasted on a wall, ceiling, or floor facing the outside air of a building, or 2) a charcoal layer is provided in the middle of a pipe of an air-conditioning facility that allows air in a house to flow, 3) A method of mixing a fine powder of charcoal into an interior material such as a vinyl cloth in a house, an adhesive, a paint, or the like is disclosed. Since charcoal sheets adsorb volatile chemical substances, volatilization and diffusion of volatile chemical substances in a house can be prevented.
[0004]
Further, Patent Document 2 discloses a method of forming a coating film layer containing charcoal powder on the inner surface of a duct of an air conditioning facility that allows air in a house to flow. The coating film layer containing charcoal powder can adsorb volatile chemicals such as ammonia and formaldehyde in the air passing through the duct, thereby preventing volatilization and diffusion in the house.

[Problems to be solved by the invention]
However, these inventions have been made with the removal of volatile chemical substances generated in the house in mind, and the countermeasures against harmful substances entering from outside the house have not been perfect.
[0007]
In particular, due to the deterioration of the urban environment in recent years, the air contains various air pollutants (hazardous substances) such as sulfur dioxide, nitrogen oxides, carbon monoxide and suspended particulate matter. Is on the rise.
[0008]
Under such circumstances, opening a window and ventilating it is not preferable because it will draw harmful substances into the house, but it is not possible to close the window.
In the case of ordinary houses, the air in the house is replaced by natural convection phenomenon, so even if the window is closed, air containing air pollutants (toxic substances) gradually enters the house. Will be drawn into.
As a result, the deterioration of the residential environment has progressed, raising concerns that adversely affect the health of residents.
[0009]
Therefore, the present invention mainly removes air pollutants (hazardous substances) contained in the air taken into the house from outside in order to prevent the environment in the house from deteriorating and to maintain and purify the house environment. An object is to provide a residential ventilation system.

DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a residential ventilation system according to the present invention will be described in detail with reference to the drawings as appropriate.
In the description of the embodiment, the same constituent elements are denoted by the same reference numerals, and redundant descriptions are omitted.
[0025]
[First Embodiment]
First, a residential ventilation system according to a first embodiment of the present invention will be described with reference to FIG. In the drawings to be referred to, FIG. 1 is a schematic configuration diagram of a house provided with a residential ventilation system according to the first embodiment.
[0026]
As shown in FIG. 1, a house (hereinafter referred to as “house”) 1 equipped with a ventilation system in a house has a first floor floor space 2 and a pothole portion that forms a flow path for guiding the introduced outside air to the attic space 3. 4, a first-floor room 5 and a second-floor room 6 adjacent to the pothole part 3, and an outside air introduction port 10 for introducing outside air are mainly provided. The “second-floor room” corresponds to the “second-floor or higher room” in [Claims].
[0027]
An outside air inlet 10 is provided through the side wall forming the first floor underfloor space 2. The outside air introduced into the first floor underfloor space 2 from the outside air introduction port 10 is introduced into the first floor living room 5 as purified air by passing through an outside air purification unit 8 described later.
[0028]
The pothole portion 4 is a space that penetrates the first floor and the second floor and communicates with the attic space 3 above the first floor underfloor space 2. For example, a staircase, a colonnade, a vertical duct, or a ventilation cylinder in a house for cold districts.
The attic space 3 has a discharge port 11 for finally discharging the air collected from the pothole 4 and the second-floor room 6 to the outside. The discharge port 11 is provided with a duct 11a so that air can be collected.
[0029]
The first-floor room 5 is provided with an air supply port 12 that communicates with the first-floor space 2 and an exhaust port 13 that communicates with the pothole 4, and the air supply port 12 is covered with the outside air purification unit 8. . Further, the second-floor room 6 is provided with an air supply port 14 that communicates with the pothole 4 and an exhaust port 15 that communicates with the attic space. In this way, air flow paths can be secured by communicating the spaces.
[0030]
Further, the first-floor room 5 (or second-floor room 6) can be partitioned by a partition 7 to form first-floor rooms 5a and 5b (or second-floor rooms 6a and 6b). In this case, the first-floor rooms 5a and 5b are each provided with an air inlet 12, the second-floor rooms 6a and 6b are each provided with an exhaust port 15, and the partition 7 is provided with a communication hole 7a. In addition, air flow paths are secured in the second-floor rooms 6a and 6b.
An undercut or the like of the door can be used for the exhaust port 13, the air supply port 14, or the communication hole 7 a that communicates with the hole portion 4.
[0031]
FIG. 2 is a schematic perspective view of the outside air purification unit.
As shown in FIG. 2, the outside air purification unit 8 includes a plurality of substantially rectangular parallelepiped tares 8 a made of nonwoven fabric, and a porous adsorbent 8 b is filled in the tare 8 a. The outside air purification unit 8 can be provided so as to cover the air supply port 12 by connecting the tare 8 a vertically and horizontally in accordance with the area of the air supply port 12.
[0032]
In the present embodiment, the outside air purification unit 8 is configured such that outside air introduced into the first floor underfloor space 2 passes through and reaches the first floor living room 5. Therefore, the mesh size of the nonwoven fabric is such that the outside air in the first floor underfloor space 2 can pass efficiently and the porous adsorbent 8b does not spill out. In addition, if the material which comprises the tare 8a is a material excellent in air permeability, durability, and workability like a nonwoven fabric, it can substitute suitably. Further, the shape and size of the tare 8a are not particularly limited, and can be changed as appropriate. Furthermore, it is also possible to adopt a configuration in which a plurality of purification treatment units 8 are provided in the vertical direction so that outside air passes through the purification treatment unit 8 a plurality of times. By doing so, more purified air is supplied into the first floor room 5 and the like.
[0033]
FIG. 3 is an example of attachment of the outside air purification unit to the air supply port.
As shown in FIG. 3, the tare 8a is fixed to the side surface of the floor joist with staples or the like. However, the attachment mode of the tare 8a is not particularly limited, and the tare 8a may be directly fixed to the lower surface of the floor plate, or the outside air purification unit 8 is formed into a plate shape and is directly attached to the lower surface of the floor plate. You may do it.
[0034]
The porous adsorbent 8b is a porous material having a large specific surface area (surface area per gram) and excellent adsorption performance. Bamboo charcoal is suitably used for the porous adsorbent 8b. However, the porous adsorbent 8b is not particularly limited, and for example, charcoal, activated carbon, and zeolite can be used.
In this embodiment, it is recommended to use bamboo charcoal as the porous adsorbent 8b. Therefore, bamboo charcoal will be described first, and then charcoal and activated carbon will be described.
[0035]
<Bamboo Charcoal>
Innumerable holes are formed in bamboo charcoal. These holes are honeycomb (honeycomb) shaped pipes, all leading to the outside. The diameters of the honeycomb-shaped pipes vary in size, and specifically, the honeycomb-shaped pipes exist in a state where a unit of 1 / 1,000,000 mm to a unit of 1/1000 mm is mixed.
[0036]
Therefore, bamboo charcoal has a specific surface area of 300m²The adsorption force is 50 to 60 g / m.²It is. Compared to Bincho charcoal, it is said that the specific surface area is twice and the adsorption power is 10 times, and the adsorption power of bamboo charcoal is very large.
[0037]
In addition, all the holes of bamboo charcoal are open to the outside world, so that not only air and water but also nutrients can be taken into the hole from the outside, creating an environment where microorganisms can easily grow inside the hole. Has been. In fact, it is known that various fungi are segregating, such as filamentous fungi in large pores, actinomycetes in small pores, and bacteria in finer gaps. ing.
[0038]
When bamboo charcoal having such characteristics is used as the porous adsorbent 7b, the following actions and effects can be obtained.
[0039]
(Removal of harmful substances)
Microorganisms are formed on the surface of the bamboo charcoal pores to form a microbial membrane, so that moisture contained in the outer periphery of the bamboo charcoal and inside the pores and impurities contained in the outside air are adsorbed and decomposed by the microbial membrane. The Here, the impurities refer to, for example, organic substances that cause odor, and harmful substances such as various harmful chemical substances and air pollutants.
[0040]
Therefore, air from which harmful substances have been removed is supplied into the house, and the environment in the house can be maintained and improved. In particular, bamboo charcoal easily adsorbs ammonia (odor components) and also absorbs the smell of pets and cigarette smoke, etc., so it is placed in the air outlets 13 and 15 and the air inlet 14 and the like. Thus, the air in the house can be efficiently purified.
[0041]
(Humidity adjustment function)
Bamboo charcoal has a honeycomb structure, so when the humidity is high, such as during the rainy season, moisture in the air is absorbed into the honeycomb structure, and conversely, when the humidity is low, such as in winter, Release absorbed moisture.
[0042]
Therefore, when bamboo charcoal is arranged in the underfloor space, the bamboo charcoal exhibits an excellent humidity control function, can control the humidity under the floor, and can prevent the occurrence of condensation and mold. Therefore, in the case of a wooden house, durability can be improved, maintenance costs can be greatly reduced, and termites caused by condensation or mold under the floor can be effectively prevented.
Furthermore, bamboo charcoal is preferable to drugs conventionally used to prevent the occurrence of mold and termites because bamboo charcoal has no toxicity to the human body, can be supplied at low cost, and the effect lasts semipermanently.
[0043]
In addition, when we actually laid bamboo charcoal and measured the humidity change under the floor, the humidity under the floor was about 5% in summer and about 10% lower in winter, and more than 95% even in the rainy season when the humidity is highest. Did not reach. Furthermore, generation of fungus under the floor was not confirmed.
[0044]
(durability)
Since the adsorption performance of bamboo charcoal is chemical adsorption by microorganisms growing in the pores, it is not affected over time. On the other hand, the adsorption performance of activated carbon is due to physical adsorption due to the size of the surface area, and the adsorption performance is lost over time. Therefore, activation processing is necessary and takes time.
[0045]
Therefore, bamboo charcoal is inferior to activated carbon in terms of adsorption power (800 m per gram in the case of activated carbon).²However, since activation treatment is not required unlike activated carbon, it can be used semipermanently.
[0046]
(Prevention of electromagnetic waves)
Since bamboo charcoal is almost entirely composed of carbon, it has excellent conductivity and power storage. Therefore, it absorbs electromagnetic waves in the same way as the principle of preventing lightning with a lightning rod. Therefore, it becomes possible to mitigate the influence on the human body caused by the electromagnetic waves in the house, which has been a problem in recent years.
[0047]
(Cost performance)
In addition, since bamboo charcoal has a large specific surface area, the amount used is only half that of using charcoal (charcoal is 50 kg per tsubo) and is economical.
[0048]
(Other effects)
In addition to these characteristics, bamboo charcoal is known to have a function of supplying minerals such as silicic acid and potassium, a far-infrared effect, and a healing effect.
[0049]
Bamboo charcoal having the functions and effects described above is suitable as the porous adsorbent 8b in the present embodiment. Bamboo charcoal carbonized at a temperature of 800 degrees exhibits the above-described characteristics better.
[0050]
<Charcoal>
Charcoal also has properties similar to bamboo charcoal.
Various kinds of wood used as raw materials for charcoal can be used, from hardwoods such as Ubamegashi, oak, oak, kunugi and chestnuts to conifers such as larch, cedar and cypress. is there.
As the carbonization method, various conventionally known methods can be applied, and the progress of carbonization is also low temperature carbonized charcoal obtained by carbonizing at 400 to 500 degrees, medium temperature charcoal charcoal obtained by carbonizing at 600 to 700 degrees, Any thing such as high-temperature carbonized charcoal obtained by carbonizing at around 1000 degrees can be used.
[0051]
<Activated carbon>
Activated carbon also has properties similar to bamboo charcoal.
Activated carbon is a carbon with fine pores made by reacting with a gas or a chemical at a high temperature using a carbon material such as coal or coconut shell as a raw material.
For example, in the case of powdered activated carbon, sawdust, hard wood chip, charcoal (primary ash), grass charcoal (peat), etc. In the case of granular activated carbon, charcoal, coconut shell charcoal, coal (sub-ash, lignite, bituminous coal, anthracite, etc. In the case of fibrous activated carbon from oil carbon, phenol resin, etc., it can be produced from rayon, acrylonitrile, coal pitch, petroleum pitch, phenol resin, and the like.
[0052]
Hereinafter, a series of air flows in the residential ventilation system in the present embodiment will be described with reference to the drawings.
[0053]
In general, when air is warmed, it expands and rises naturally (natural convection phenomenon). Therefore, the outside air led into the first floor underfloor space 2 of the house 1 provided with the in-house ventilation system according to the present embodiment is warmed in the first floor underfloor space 2 to generate an updraft. Therefore, the air supplied into the house 1 rises and is discharged outside the house 1 through the attic space 3.
[0054]
First, the outside air that has passed through the outside air inlet 10 and introduced into the first floor underfloor space 2 rises due to the natural convection phenomenon in the house 1, and moves in the first floor underfloor space 2 toward the air inlet 12. To do. Since the air supply port 12 is covered with the outside air purification unit 8, the raised outside air enters the outside air purification unit 8.
[0055]
Since the outside air purification unit 8 is filled with bamboo charcoal, which is a porous adsorbent 8b, the outside air that has entered the outside air purification unit 8 passes through the outer periphery of the bamboo charcoal or inside the tube of the bamboo charcoal honeycomb structure. At this time, due to the effect of the bamboo charcoal described above, adsorption removal of impurities and the like in the outside air and other suitable treatments are performed on the outside air.
Then, the air after impurities and the like are removed by adsorption from the outside air is supplied from the outside air purification unit 8 to the first floor room 5 through the air supply port 12.
[0056]
The air supplied to the first-floor room 5 is discharged into the pothole 4 through the exhaust port 13 along the flow path. When the first-floor room 5 is partitioned into the living rooms 5 a and 5 b by the partition 7, the air supplied to the first-floor room 5 b that is not adjacent to the pothole 4 is exhausted to the first-floor room 5 a through the communication hole 7 a of the partition 7. After being discharged, it is discharged into the hole 4.
[0057]
In the pothole 4, upward airflow is generated toward the attic space 3. Therefore, although the air discharged to the pit hole 4 rises toward the attic space 3, a part of the air is supplied into the second-floor room 6 from the air supply port 14 provided in the middle of the flow path. When the second-floor room 6 is partitioned into the second-floor rooms 6 a and 6 b by the partition 7, first, the air supplied to the second-floor room 6 a adjacent to the pothole portion 4 is connected to the pothole portion through the communication hole 7 a of the partition 7. 4 is supplied to the second-floor room 6b that is not adjacent to 4.
[0058]
And the air supplied to the second-floor room 6, 6a, 6b is discharged | emitted from the exhaust port 15 to the attic space 3, and is discharged | emitted outside from the discharge port 11 through the duct 11a.
Thus, ventilation of the house 1 is performed by the flow of the purified air, and the maintenance and purification of the environment in the house can be achieved.
[0059]
In addition, the following structures can also be added to the house 1 provided with the house ventilation system which concerns on this Embodiment.
[0060]
For example, the fan 16 which is an air supply means can be provided in the first floor underfloor space 2. By providing the fan 16, outside air is forcibly supplied into the underfloor space 2, and outside air in the first floor underfloor space 2 is forcibly supplied from the first floor underfloor space 2 to the first floor room 5. . Thereby, since the air in the house 1 can be replaced in a shorter time than in the case of using the above-described natural convection phenomenon, the environment in the house can be purified more effectively.
[0061]
The position where the fan 16 is provided is not limited to the first floor underfloor space 2. For example, the fan 16 is provided in the attic space 3 and the air in the house 1 is forcibly discharged to the outside. It can also be set as the structure provided in both 2 and the attic space 3. FIG.
[0062]
In the configuration in which the fan 16 is provided, in the vicinity of the discharge port 11 of the duct 11a, a sensor for detecting the concentration of volatile chemical substances and the amount of dust contained in the air released from the duct 11a to the outside of the house 1, Appropriate detection means 17 such as a sensor for detecting the temperature, humidity, and air volume of the released gas is provided, and the operation of the fan 16 is determined based on the results detected by these sensors. You can also. In this case, ventilation in the house 1 can be effectively performed as necessary.
[0063]
For example, the heater 18 which is a heating means can also be provided in the underfloor space 2 of the first floor. By providing the heater 18, the outside air guided into the first floor underfloor space 2 can be warmed. The warmed outside air expands and becomes light, and an updraft is generated in the house. Therefore, ventilation in the house 1 can be more effectively promoted.
Further, in the winter season, the outside air heated by the heater 18 can be supplied from the first floor underfloor space 2 into the first floor rooms 5, 5a, 5b, the second floor rooms 6, 6a, 6b, and the pothole portion 4, thereby assisting heating. The consumption of energy used for heating can be reduced.
[0064]
[Second Embodiment]
Next, a residential ventilation system according to a second embodiment of the present invention will be described with reference to FIG. In the drawings to be referred to, FIG. 4 is a schematic configuration diagram of a house provided with the in-house ventilation system according to the second embodiment.
[0065]
As shown in FIG. 4, a house (hereinafter referred to as “house”) 1 ′ equipped with a ventilation system in a house has a first floor underfloor space 2 and a pit that forms a flow path that guides the introduced outside air to the attic space 3. The unit 4 is mainly provided with a first-floor room 5 and a second-floor room 6 adjacent to the pothole 3 and an outside air inlet 10 for introducing outside air.
[0066]
An outside air purifying unit 20 for purifying the introduced outside air is disposed in the first floor underfloor space 2. The outside air purification unit 20 is formed so that a space surrounded by a reinforced concrete solid foundation and side walls 20a rising from the solid foundation is filled with the porous adsorbent 8b and covered with a lid 20b. Has been.
[0067]
A material other than wood is used for the lid 20b. This is because the wood used in the first floor underfloor space 2 needs to be impregnated with a chemical or the like for termite extermination, and this prevents the air from being newly contaminated by touching it. However, the material of the lid 20b is not particularly limited and can be changed as appropriate. For example, a fireproof plate such as a fireproof board, a calcium plate, or a flexible board can be suitably used.
[0068]
A pipe 21 that passes through the side wall 20 a and communicates with the outside air inlet 10 and a pipe 22 that communicates with the air inlet 12 provided in the first-floor room 5 are connected to the outside air purification unit 20. The outside air introduced from the outside air inlet 10 is directly introduced into the outside air purification unit 20 via the pipe 21 and then supplied to the first floor room 5 via the pipe 22 as purified air.
[0069]
The porous adsorbent 8b may be directly filled into the space formed as described above, or may be filled into the tare 8a described in the first embodiment and fixed with staples or the like. It may be. Further, the porous adsorbent 8b may be one that fills the entire space in order to maximize its effects, or only a part of the space in order to reduce costs. Also good.
[0070]
Therefore, the outside air does not directly touch the members such as wood facing the first floor underfloor space 2 or the air in the first floor underfloor space 2, and is not newly contaminated in the first floor underfloor space 2. 5 is supplied. In particular, since wood is impregnated with various chemicals for termite control and the like, it is preferable not to touch it. The air flow path from the first-floor room 5 is the same as that in the first embodiment, and a description thereof will be omitted.
As described above, the ventilation of the house 1 ′ is performed by the flow of the purified air, and the environment in the house can be maintained and purified.
[0071]
If the fan 16 is attached to the pipe 21, the outside air can be forcibly introduced into the outside air purification unit 20 and can be forcibly supplied into the first-floor room 5 as purified air. As a result, the house can be ventilated in a short time, and the environment in the house can be purified more effectively.
[0072]
Further, the heater 18 can be provided inside the outside air purification unit 20. By providing the heater 18, the outside air guided into the outside air purification unit 20 can be warmed. The warmed outside air expands and becomes light, and an updraft is generated in the house. Therefore, ventilation in the house 1 'can be more effectively promoted. In addition, in the winter season, warm outdoor air can be supplied into the house, so that heating is supported and the amount of energy used for heating can be reduced.
[0073]
Furthermore, if the outside air purification part 8 is provided in the passage communicating from the pothole part 4 to the attic space 3, the environment in the house can be improved by various functions of the porous adsorbent 8b. Specifically, the humidity adjusting function can dehumidify the interior space of the house when the humidity is high, and can effectively prevent condensation and mold.
[0074]
As described above, the residential environment purification system according to the second embodiment has been described. However, the outside air purification unit 20 may be modified as follows.
FIG. 5 is a modified example of the outside air purification unit, and FIG. 6 is a perspective view of the box.
As shown in FIG. 5, the outside air purification unit 23 includes a box body 24 in a space formed by the side wall 20 a and the lid 20 b. The box 24 has an opening 24a at the top, and is filled with a porous adsorbent 8b (see FIG. 6). Moreover, the piping 22 connected to the air supply opening provided in the first floor room 5 is connected to the side wall 20a like the above.
[0075]
The pipe 25 communicating with the outside air inlet 10 passes through the side wall 20 a and is connected to the box body 24. By doing so, the outside air introduced from the outside is directly guided to the inside of the box body 24 and purified by the action of the porous adsorbent 8b. This purified air is supplied from the opening 24 a of the box body 24 through the pipe 22 into the first floor room 5.
[0076]
Therefore, the air does not directly contact a member such as wood facing the first floor underfloor space 2 or the air in the first floor underfloor space 2, and new contamination in the first floor underfloor space 2 can be prevented. Further, since the box 24 filled with the porous adsorbent 8b is used instead of directly filling the porous adsorbent 8b in the outside air purifying section 23, the layout inside the outside air purifying section 23 can be easily changed. can do. Therefore, the heater 18 and the like can be easily arranged in the outside air purification unit 23. Further, since the box body 24 is formed in a compact shape, it can be easily replaced.
[0077]
In addition, by arrange | positioning this box 24 in a house, the environment in a house can be improved with the various functions of the porous adsorbent 8b with which the box 24 was filled. For example, by providing a box 24 near the passage communicating from the pothole 4 to the attic space 3, when the humidity is high, the porous adsorbent 8b dehumidifies the house and effectively prevents dew condensation, mold, etc. it can.
[0078]
As mentioned above, although the preferable aspect of the ventilation system in a house which concerns on this Embodiment was demonstrated, this invention is not limited to this. For example, in the present embodiment, the case where the present invention is applied to a two-story house has been described. However, the residential ventilation system according to the present invention is also applied to a building having two or more stories (for example, three stories, four stories). be able to.
[0079]
【The invention's effect】
In the residential ventilation system according to the present invention, outside air is introduced into the house, passes through the outside air purification unit, and then supplied to the first floor room. The outside air purifying section is filled with a porous adsorbent, and harmful substances contained in the outside air are adsorbed on the porous adsorbent, so that the outside air after the air pollutant (hazardous substance) is removed. However, it is guided to the space in the house and can maintain and purify the environment in the house.
[0080]
In addition, when outside air is introduced into the first floor underfloor space, passed through the air supply port covered with the outside air purification unit, and supplied to the first floor room as purified air, the outside air can be simply configured. The purification part can be easily attached.
[0081]
On the other hand, after the outside air is directly introduced into the outside air purifying section, it is possible to prevent the air from being newly contaminated in the space under the first floor by connecting the pipe so that the purified air can be directly supplied to the first floor room. . Therefore, it is possible to effectively maintain and purify the residential environment.
[0082]
At this time, if an air supply means is provided in the first floor underfloor space or the attic space, the air after impurities and air pollutants (hazardous substances) are removed is reliably supplied to the space in the house. Thereby, compared with the case where natural convection is used, the maintenance and purification of the residential environment is performed more efficiently. Moreover, since the outside air cooled in the space under the first floor can be supplied to the space in the house in the summer, it can be used to assist the cooling in the house.
[0083]
Furthermore, when an appropriate heating means is provided, the outside air can be warmed. The warmed outside air expands and lightens to generate an updraft. Thereby, the flow of air can be made smooth and ventilation in a house can be performed efficiently. In winter, it can be used to assist heating in the house.
