Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ductless central exhaust system for an apartment house, and more particularly, to a ductless central exhaust system.
This is related to ductless central exhaust in reinforced concrete condominiums.

[0002]

2. Description of the Related Art Reinforced concrete apartment buildings, including condominiums,
It is very airtight because it is surrounded by concrete and aluminum sash. In order to reduce the concentration of air pollutants generated indoors and to remove indoor moisture, it is necessary to introduce fresh outside air and actively perform indoor ventilation. Then, just install the range hood provided in the kitchen and the exhaust device for sanitary such as toilet and bathroom,
Almost no ventilation system is installed for each room such as a living room or a private room. Therefore, the ventilation of each room must rely on natural ventilation, but natural ventilation can hardly be expected in highly airtight condominiums and the like.

Here, when ventilating the living room,
If the exhaust duct for the living room is piped in addition to the exhaust duct for the kitchen and the sanitary exhaust duct, the exhaust duct from each room will intersect with the exhaust duct for the kitchen and the sanitary exhaust duct. Construction work becomes complicated. In addition, a lot of space in the height direction in the ceiling is required at the intersection of the exhaust duct, and this intersection space cannot be secured in a building with a low floor height such as an apartment.

Accordingly, in apartment buildings such as reinforced concrete condominiums, not only ventilation for sanitary facilities such as toilets and bathrooms, but also active ventilation of living rooms and private rooms, etc. A technical problem to be solved arises in order to construct a ductless central exhaust system by concentrating an exhaust path in a ceiling space, and an object of the present invention is to solve this problem.

[0005]

SUMMARY OF THE INVENTION The present invention has been proposed in order to achieve the above object. In a reinforced concrete apartment house, a partition wall of a corridor is raised up to the lower surface of a concrete slab on an upper floor. An assembly in which a closed space is provided in a ceiling of a corridor to form an exhaust chamber, exhaust from a living room is introduced into the exhaust chamber, and air in the exhaust chamber is exhausted to the outside of the house by a fan. A residential ductless central exhaust system is provided.

[0006]

Embodiments of the present invention will be described below in detail with reference to the drawings. 1 and 2 show a room in a reinforced concrete apartment building as an example of an apartment house. A concrete wall 15 is cast between a pillar 12 on the side of the outer corridor 11 and a pillar 14 on the balcony 13 side. And a partition has been built. In addition, between the pillars 12,12 and the pillars 14,1
The beams 16 and 17 are provided between the four, and the upper and lower layers are partitioned by the concrete slab 18. A steel door 20 is provided at an entrance 19 on the outer corridor 11 side.
Since the glass door 21 and the window 22 of the aluminum sash are provided on the balcony 13 side, the airtightness of the room of the apartment surrounded by the concrete and the aluminum sash is extremely high.

Generally, the living room 23 is located on the balcony 13 side.
In many cases, a dining room 24 is arranged and a hallway 25 connects the entrance 19 to the living room 23 or the dining room 24. Corridor 2
Living rooms such as Western rooms 26 and 27 and a Japanese room 28 are arranged on the left and right of 5, and sanitary facilities such as a toilet 29, a lavatory 30, and a bathroom 31 are arranged. A kitchen 32 is provided adjacent to the dining room 24. . A storage is attached to each room, and closets 33 and 34 are provided in Western rooms 26 and 27, respectively.
A closet 35 is also arranged in the corridor 25. In addition, Japanese-style room 2
8 is provided with a closet 36.

Next, the ventilation system will be described. Regarding the introduction of outside air, air supply ports 37 are provided in the living room 23, the dining room 24, and the Western rooms 26 and 27, respectively.
Thus, outside air is introduced from the outside corridor 11 and the balcony 13 into each living room. The introduced air is also supplied to the Japanese-style room 28 and the kitchen 32 through the living room 23 and the dining room 24. On the other hand, outside air from the entrance 19 is introduced into the sanitary facilities such as the toilet 29, the washroom 30, and the bathroom 31 via the corridor 25. For this reason, vents and undercuts are provided in the doors of the toilet 29 and the lavatory 30 in the same manner as in the prior art to allow air to flow.

FIG. 3 shows an exhaust path provided in the ceiling. The ceiling 25a in the corridor and the ceiling 32a in the kitchen rise up to the lower surface of the concrete slab 18 on the upper floor to form a closed space. In addition, ceiling 3 of each closet
The ceiling of the storage, such as the ceiling 3a, 34a, 35a and the closet 36a, is also closed by the partition wall 38, and the exhaust chamber 39 is formed by these closed spaces. Kitchen ceiling 3
2a, an exhaust port 40 is provided on each of the closets ceilings 33a, 34a, 35a and a closet ceiling 36a, and a ventilation port 42 is provided at a connection portion of the exhaust chamber 39. Or,
Where ventilation is required, the partition wall 38 is not raised up to the lower surface of the concrete slab 18 to secure a space for ventilation. Then, the air in the exhaust chamber 39 is discharged to the outside by the living room fan 43.

On the other hand, the kitchen 32 has a range hood 44.
The duct 45 dedicated to the range hood is connected to the outside through the exhaust chamber 39. An exhaust port 46 is provided in each of the toilet 29, the washroom 30, and the bathroom 31, and a sanitary duct 47 is connected to the outside through the exhaust chamber 39. Then, the air in the sanitary duct 47 is discharged to the outside by the sanitary fan 48.

As described above, since the exhaust chamber 39 is formed in the ceiling, the living room can be exhausted without special piping of a dedicated exhaust duct. On the other hand, since the kitchen exhaust containing hot air and cooking smoke and the sanitary exhaust containing a large amount of moisture and odor are performed in a duct system, pollution to other areas can be prevented. In addition, since these ducts 45 and 47 are housed in the exhaust chamber 39, construction work in which an exhaust duct dedicated to a living room and a duct for kitchen exhaust or sanitary exhaust are crossed can be avoided, and the ducts intersect. Space can be saved, and a central exhaust system can be built even in narrow ceilings such as apartments.

FIG. 4 shows a closet 33 as an example of an exhaust device inside the storage. As described above, an exhaust port 40 is provided in the ceiling 33a of the closet, and an exhaust chamber 39 is formed in the ceiling 33a. . Closet door 49
Is provided with a vent 50 so that air can flow therethrough. By the operation of the living room fan 43 described above, the Western room 2
The air 6 enters the inside of the closet 33 from the vent 50 of the door 49 and is discharged from the exhaust port 40 to the outside through the exhaust chamber 39.

Accordingly, the air in the storage is ventilated to reduce the humidity, thereby preventing the formation of dew and mold. In particular, when the closet 33 is in contact with the outer wall of the building, dew condensation often occurs on the inner wall surface due to a decrease in the outside temperature in winter. However, by flowing warm air from the room into the closet 33, Effective for preventing condensation. Also, even if an insect repellent is set in the closet 33, the air is
, The odor of the insect repellent and harmful substances do not flow out into the room. Since the operating noise of the living room fan 43 is reduced by the stored items in the closet 33, the effect of the noise into the room can be ignored.

FIG. 5 shows a closet 36 as another example of the storage.
A ventilation hole 52 is opened in the sliding door 51, and a floorboard 53 in the shape of a mushroom is provided inside. In addition, the closet 3
An exhaust port (not shown) may be provided in the ceiling 36a of the closet as in the case of 3 and air in the closet 36 may be exhausted from the exhaust port to the exhaust chamber 39, but in the present embodiment, the exhaust port is connected to the exhaust port. Instead, the wall 54 constituting the closet is made air-permeable, and the air in the closet 36 is exhausted to the exhaust chamber 39 through the wall 54.

As shown in FIG. 6, the wall 54 is formed by a spacer 56 and a steady rest 57 between two plaster boards 55.
Are formed in a sandwich structure, and a number of holes 58 or slits (not shown) are formed in one or both plaster boards 55 in advance. The space between the two plaster boards 55 acts as a ventilation chamber 59, and air flows in from the hole 58 and flows through the ventilation chamber 59.

In constructing the closet 36 with the wall 54, when there is another room or corridor adjacent to the closet 36, as shown in FIG.
5, a wall body 54 having a hole 58 formed therein is used.
To the closet 36 side to partition. If the closet 3
When there is another storage such as a closet behind or on the side of 6, as shown in FIG. 6B, a wall 54 having holes 58 formed in both plaster boards 55 is used. The storage and the ventilation chamber 59 can be shared to partition the storage.

In the closet 36 shown in FIG. 5, the air in the Japanese room 28 enters the inside of the closet 36 from the vent 52 of the sliding door 51 by the operation of the fan 43 for the living room, and Air flows through the ventilation chamber 59 of the body 54 and is discharged to the outside from the exhaust chamber 39 in the ceiling.

Accordingly, similarly to the above-described closet 33, the air in the storage is ventilated to reduce the humidity, thereby preventing the formation of dew and mold. In particular, even when the stored items are pressed against the wall 54 or stored until the height of the ceiling 36a of the closet is reached, the air directly flows into the wall 54 so that the exhaust can be reliably performed. In addition, since the floor plate 53 has a double-blanket structure, air can flow from above and below the floor plate 53 and the flow of air in the closet 36 can be improved. Furthermore, since the wall used so far is used almost as it is, the initial cost can be kept low and, unlike the conventional case, there is no need to provide a special ventilation space in front of the wall. Since the 54 itself functions as a ventilation chamber, the exhaust device can be constructed with the same space size as the conventional closet without reducing the storage space.

The wall 54 having the ventilation chamber 59
Can be used not only in closets but also in other storages such as closets, and the exhaust device using the wall 54 can be applied not only to apartments and other collective houses but also to single-family houses. Further, instead of the exhaust chamber in the ceiling, an exhaust duct may be directly connected to the upper part of the ventilation chamber 59 of the wall 54.

FIG. 7 is a block diagram showing the configuration of the ventilation system, in which the indoor ventilation system is divided into three zones: a private zone, a public zone, and a sanitary zone. First, private rooms such as the Western rooms 26 and 27 are set as private zones, and outside air is introduced from the air supply port 37 into the Western rooms 26 and 27. The operation of the fan 43 for the living room causes the Western room 2 to operate.
The air 6 and 27 pass through the closets 33 and 34 and are discharged from the exhaust port 40 to the outside through the exhaust chamber 39 in the ceiling. In the private zone, there is no air flow between each room and the corridor 25 during ventilation, and there is no need to form a vent or an undercut in the door of each room. Therefore, light and sound do not leak from the door of the living room, and privacy as a private room can be maintained.

Next, the living room 23, the dining room 24, the Japanese-style room 28, and the kitchen 32 are made public zones, and the living room 2 is
3. The outside air is introduced into the dining room 24. Then, the air in the living room 23 flows into the Japanese room 28 by the operation of the fan 43 for the living room. The air that has flowed into the Japanese room 28 passes through the closet 36 and is discharged to the outside from the exhaust port 40 or the above-described permeable wall 54 through the exhaust chamber 39 in the ceiling.
The air in the dining room 24 flows into the kitchen 32. Kitchen 32
In many cases, indoor air is heated and stagnated due to heat radiation from a refrigerator, a rice cooker, an electric kettle, and the like, and the stagnant air in the kitchen 32 flows from the exhaust port 40 to the ceiling through the operation of the living room fan 43. The air is exhausted to the outside through the exhaust chamber 39 inside.

The zoning between the private zone and the public zone may vary somewhat depending on the resident's lifestyle and family structure. For example, the Japanese-style room 28 may be used as a bedroom, but the Japanese-style room 28 adjacent to the living room 23 is considered as a space continuous with the living room, and the structure partitioned by the sliding door cannot sufficiently block light and sound. , The Japanese-style room 28 is included in the public zone.

In the private zone and the public zone, the fan 43 for the living room is continuously operated at a constant rotation in order to secure an air volume required for ventilation. The air volume required for ventilation is about 20 m ³ / h in a room between 6 to 10 tatami mats.
The kitchen 32 has a large amount of heat, so if it needs about 60 m ³ / h, the fan 43 for the living room is always 120 to 1
An air volume of about 30 m ³ / h is generated. If a variable flow rate type exhaust port is used as the exhaust port 40, the exhaust volume of each room can be separately adjusted, and planned ventilation can be performed.

Further, the toilet 29, the washroom 30, and the bathroom 31 are made into a sanitary zone, and outside air from the entrance 19 is introduced into the toilet 29 and the washroom 30 through the corridor 25, and the bathroom 31 passes through the washroom 30. Air is introduced. By the operation of the sanitary fan 48, air in the toilet 29, the lavatory 30, and the bathroom 31 flows from the exhaust port 46 to the sanitary duct 47.
Is discharged to the outside through In the sanitary zone, when the sanitary equipment is used, an air volume of about 130 to 140 m ³ / h is required. The temperature difference between the living room 23, the living room such as the Western rooms 26 and 27, and the corridor 25 becomes large.

In order to prevent this, the sanitary fan 48 is provided with a control device 60 for switching the flow rate between high and low. In addition, the lighting switch 61 of the toilet 29, the lavatory 30, the bathroom 31, or the ventilation switch 62 is provided separately,
The control device 60 is formed to be switched to the enhanced position in conjunction with the ON operation of the lighting switch 61 or the ventilation switch 62.

When the sanitary equipment is not used, the control device 60 is at a weak position, so that the sanitary fan 4 is not used.
8 is operated slightly, and the sanitary zone is ventilated with a small air flow of about 40 m ³ / h. On the other hand, when the sanitary equipment is used, the control device 60 is switched to the augmenting position, so that the sanitary fan 48 is automatically augmented, and a large air volume of 130 m ³ / h or more necessary for ventilation of the sanitary zone is secured.

Here, the range hood 44 of the kitchen 32 is 2
Except for a large air volume of about 00 to 600 m ³ / h, and the use of a simultaneous supply / discharge type range hood (a type that has a dedicated air supply duct and can supply air without going indoors), it corresponds to the air supply path Since the space becomes excessively ventilated, supplying air from a private zone or a public zone disturbs the indoor environment. For this reason, the range hood 44
When air is supplied to the outside, the outside air introduced from the entrance 19 which is considered to have the least effect on the comfort is used. Since the range hood 44 is used only during cooking and is not always operated continuously, it is unavoidable to introduce outside air via the corridor 25. Part of the outside air introduced from the entrance 19 passes through a closet 35 provided in the corridor 25 by the operation of the fan 43 for the living room, and
From 0, the air is exhausted to the outside through an exhaust chamber 39 in the ceiling.

As described above, the fan 43 for the living room is continuously operated at a constant rotation. Further, the sanitary fan 48 is slightly operated even when the equipment is not used, and when the toilet 29 or the bathroom 31 is used, the exhaust can be increased by a natural switch operation such as turning on the light. Therefore, fresh air is always introduced and the room is ventilated without the resident operating the exhaust system with special consideration.This reduces moisture and prevents dew condensation and mold / mite breeding. The whole house can be ventilated.

The ventilation system is continuously operated day and night. However, when the resident leaves the house for a long time, the central control switch 63 is turned off. The operation of the ventilation system can be completely stopped. The central control switch 63 is installed in, for example, the inside of a switchboard, and the central control switch 63 is normally turned on so that a resident cannot easily turn off the switch.

Thus, the present invention can be variously modified without departing from the spirit of the present invention, and it goes without saying that the present invention extends to the modified ones.

[0031]

As described above, according to the present invention, a special exhaust duct is specially provided by providing a closed space in a ceiling of a corridor and forming an exhaust chamber in an apartment house or the like. The room can be evacuated without the need. The exhaust chamber can be formed only by raising the partition wall up to the lower surface of the concrete slab on the upper floor, and the exhaust chamber can be constructed at the same time as the partition wall is constructed. It is efficient.

In addition, a kitchen exhaust duct and a sanitary exhaust duct can be housed in the exhaust chamber. In such a case, the space where the exhaust system of the living room intersects with the ducts of the other exhaust systems can be saved. it can.

Thus, even in a limited ceiling space such as a condominium or the like, a ductless central exhaust system can be constructed by concentrating the exhaust path, so that not only the sanitary ventilation but also the entire house including the living room can be ventilated. Become.
