Description

  The present invention relates to an improvement in a ductless ventilation system for detached houses and apartment buildings, and more specifically, a ceiling hood of a house is used as an air supply chamber or an air passage that replaces an air supply duct, and a forced exhaust means such as a range hood is used. The present invention relates to a residential ductless air supply / exhaust system constructed so as to be able to supply air from at least a ceiling surface to each room in response to the wind pressure of operating or introduced outside air. “Ventilation” and “supply / exhaust”, “ventilation fan” and “exhaust fan” are used interchangeably.

  Conventionally, a ventilation system in which a ventilation fan is installed in a detached house or an apartment house is known. In this ventilation system, when a ventilation fan having the ability integrated on each floor or one building is installed, a ventilation fan may be installed in each room that needs ventilation.

  By the way, since recent houses have been made highly airtight in order to obtain high heat insulation properties, ventilation with only exhaust creates negative pressure inside the house, which may cause problems in opening and closing windows and doors, Insufficient ventilation may occur. For this reason, it is necessary to ventilate by actively introducing fresh outside air by forced air supply or the like.

  Furthermore, for the purpose of ventilation, it is important to quickly exhaust harmful gases, which are the cause of smoking and sick house syndrome, so as not to stay in the room.

  The conventional ventilation system is configured to provide an air supply duct in the section from the air supply fan that forcibly introduces outside air to the air supply port of the room, so a space for laying the duct is required in the ceiling. there were.

  However, in the ceiling space, a beam or the like becomes an obstacle, and there is a case where the ceiling is lowered because there is no effective height for installing the duct, and it has been forced to sacrifice in terms of design such as aesthetics.

  In addition, when responding without providing a falling ceiling, there is a case where the ventilation air volume is suppressed as much as possible to reduce the size of the duct, and in terms of ventilation capacity, necessary ventilation from the combustion air / odor around the kitchen gas stand The problem is that the necessary amount of ventilation from the volume and exhalation of the person cannot be secured.

  On the other hand, in general apartment houses, outside air inlets (ventilation ports) are provided on the outer wall under the ceiling such as the waist wall, and outside air is introduced by suction load such as forced exhaust. Since it directly flows into the height of the living area where people live, it affects the temperature and humidity of the air-conditioned room, and the indoor temperature of the person feels a draft and adversely affects the sensible temperature from the sensation of hot and cold. Effect. For example, when a range hood (forced exhaust means) is operated in the kitchen, the outside air required to cover a large amount of exhaust air is supplied from the outside air inlet on the outer wall under the ceiling of the room through the room. There is a problem that the temperature of the room air conditioner becomes insufficient because the load is also temperature-controlled, and the temperature and humidity of the living area of the room is disturbed.

Under these circumstances, the detached house has a structure in which the ceiling of each room on the same floor and the lower part of each room are connected by a communication part, and a circulating air supply fan is installed in the ceiling of an appropriate room. There has been a proposal for a ductless ventilation system for a detached house in which an exhaust fan for exhausting air from other rooms to the outside is installed in the ceiling of the room (see, for example, Patent Document 1).
JP 2003-50034 A

  Here, an outside air intake duct connected to the outside air inlet is connected to the suction side of the circulation type air supply fan, and an air supply duct is connected to the discharge side, and its end is opened in the ceiling of the adjacent room. The ceiling has an outlet to the room. Further, a reflux duct is further connected to the suction side of the circulation type air supply fan, and an end thereof is opened to the adjacent room or hallway side, and this opening and an appropriate place on the suction side of the circulation type air supply fan are arranged. Is equipped with an air purifier. In addition, there is a modification proposal that a slit is configured as a communication part in the ceiling of each room on the same floor.

For reinforced concrete apartment buildings, the partition walls of the hallway are raised to the lower surface of the concrete slab on the upper floor, a closed space is provided in the ceiling of the hallway, and an exhaust chamber is formed. Exhaust air in the room other than the exhaust system for the room is provided in the exhaust chamber at the place facing the ceiling of the closet or closet facing the room, and is introduced into the exhaust chamber through this exhaust port, and the outside of the house by the fan There has been a proposal of a ductless central exhaust system for apartment buildings that is forced to exhaust (see, for example, Patent Document 2).
Japanese Patent Laid-Open No. 10-185271

  Here, the exhaust path of the living room is concentrated in the exhaust chamber formed in the ceiling space to actively ventilate each room.

  However, although the said patent document 1 comprises a part of ceiling space as an air supply chamber, the circulation air supply fan is required, the space of a fan or a duct is required in a ceiling, and installation cost cannot be disregarded. In addition, the exhaust system is a forced exhaust means for kitchens and sanitary, and since the outside air necessary to cover the exhaust is supplied from the outside air inlet on the outer wall under the ceiling of the room through the room, the heat load of the room air conditioner also increases. The conventional problem is not solved.

  In the above-mentioned Patent Document 2, a part of the ceiling space is configured as an exhaust chamber and forced exhaust is performed. However, there is no change in the forced exhaust means and the air supply path of the kitchen or sanitary, and the outside air inlet is located on the outer wall under the ceiling of a living room or the like Since opening is necessary, conventional problems are not solved in terms of adverse effects on air conditioning in the above-described rooms (temperature / humidity fluctuations) and adverse effects on the perceived temperature from the feeling of hot and cold people feeling the draft style. .

  Speaking of the problems of the above prior art in comparison with the present invention, the presence of air supply fans and ducts installed in the ceiling, the presence or absence of lack of capacity resulting from the extra heat load processing due to the introduction of outside air for other rooms in the room air conditioner, It is the presence or absence of direct air supply in the kitchen (large air supply accompanying odor and combustion heat exhaust). By the way, in the sanitary space of toilets and bathrooms, it is normal not to provide an air supply opening that opens to the inside of the door, but to make it a small undercut, and only use a forced exhaust means (ceiling fan or ventilation unit) to the outside. is there. This is because a slight negative pressure state is desired when considering the smell and moisture diffusion.

  The technical solution is to use the ceiling space of the house as an air supply chamber or air duct as an alternative to using the air supply and exhaust structure of the house without using a duct. It is to introduce a supply / exhaust system that can supply air to each room in response to wind pressure. In detached houses and apartment houses, for the kitchens that require the maximum amount of exhaust to generate odors and combustion heat, the outside air is guided directly to the kitchen by the suction load of the range hood without passing through the living room to cover the exhaust. Can do. For this reason, it is an extra heat load for the air conditioner in the room, and the fluctuating outside air load can be reduced. The air temperature and humidity fluctuations in the room can be prevented, and the sensation that comes from the hot and cold sensation of people by feeling the draft of the outside air It is possible to prevent adverse effects on temperature, and energy supply / exhaust equipment is provided.

  In this case, do not provide ventilation openings (outside air intakes) on the outer wall under the ceiling such as the waist wall, do not provide forced air supply means in the ceiling space, and operate the range hood and other forced exhaust means. It is important that air can be supplied from the ceiling surface of each room (downward) in response to the suction load or the wind pressure of the introduced outside air.

  Here, the point to be considered in particular is that a ceiling air inlet (a first air inlet described later) of a room (for example, a living room) in which an air supply box is installed is formed in the vicinity of an air inlet of an air conditioner such as a wall-mounted room air conditioner. In addition, by naturally supplying air through a variable flow rate type air control means (Gulari), the air conditioning is disturbed, specifically, the flow of indoor air and wasteful heat loss are prevented. In addition, it is mentioned as one of the subjects that the restrictions concerning arrangement | positioning of furniture etc. are canceled by this.

  The present invention has been made in view of such circumstances, solves the above problems, uses the ceiling space of the house that was a dead space as an air supply chamber or an air passage, and is used for a forced exhaust means such as a range hood. A residential ductless air supply / exhaust system constructed so as to be able to supply air to each room at least from the ceiling surface in response to the wind pressure of the operating or introduced outside air.

In order to solve the problem, the present invention uses a ceiling space of a house as an air passage, and can supply air to at least the rooms from the ceiling surface in response to the operation of forced exhaust means such as a range hood or the wind pressure of the introduced outside air. A residential ductless air supply and exhaust system constructed in
The ceiling space of each room is connected to form a total ceiling space consisting of one space configuration, and a ceiling air inlet is formed in each kitchen, living room and other rooms except sanitary,
By introducing outside air from a part of the outer wall in the ceiling, the entire ceiling space is used as an air supply chamber.

Further, a residential ductless air supply / exhaust system constructed so as to be able to supply air to each room by using the ceiling space of the house as an air supply chamber or an air passage to replace the air supply duct,
The ceiling space of each room is communicated to form a total ceiling space consisting of one closed space configuration, and an air supply box is arranged in the ceiling of an appropriate room, and the outside air introduction formed on one surface of the air supply box A duct is interposed between the opening and the outside air inlet formed in the outer wall of the ceiling to naturally open the path to the outside, and the first air inlet and Two air supply openings are formed, the first air supply opening is opened to the ceiling on the room side, and the second air supply opening is formed opposite to the outside air introduction opening to face the entire ceiling space. The ceiling air inlet is formed in the kitchen and other rooms except sanitary,
The air supply box is used as a starting point for introducing outside air, and air is supplied to each room from at least the ceiling surface in response to the suction load by the operation of a range hood or other forced exhaust means or the wind pressure of the introduced outside air. It is characterized by this.

  In the present invention, the entire ceiling space of a house is configured as an air supply chamber or an air passage (in place of a duct), thereby responding to the suction load caused by the operation of a range hood or other forced exhaust means or the wind pressure of the introduced outside air. It is possible to supply air from the ceiling (air supply port) to each room. It should be noted that an outside air intake is not required on the indoor outer wall.

  Here, no air supply fan is installed in the entire ceiling space. In other words, there is a forced exhaust means (range hood) in the kitchen, and when this is activated, the section of one household becomes negative pressure, and the ceiling space (ceiling air inlet) makes the whole area ceiling space in a negative pressure state. Since the outside air is inevitably introduced and the interior of the ceiling (space) is supplied to each room as an air passage, there is no need to provide an air supply fan. The air flow at the time of air supply goes downward from the ceiling surface to the door louver or undercut of the room, but it is not possible by considering the arrangement relationship between the inlet of the wall-mounted room air conditioner and the ceiling air supply port as described later. The influence of airflow that contributes to pleasantness and air conditioning disturbance can be avoided.

  In addition, by providing a ceiling air supply port in the kitchen, it is possible to cope with a large amount of outside air introduction due to forced exhaust, and to minimize the inflow from the living room. For this reason, it is an extra heat load for the air conditioner in the room, and the fluctuating outside air load can be reduced. The air temperature and humidity fluctuations in the room can be prevented, and the sensation that comes from the hot and cold sensation of people by feeling the draft of the outside air It is possible to prevent adverse effects on temperature, and energy supply / exhaust equipment is provided.

  Also, assuming that there are air conditioners such as wall-mounted room air conditioners in the living room, the outside air temperature is adjusted immediately by providing a ceiling air supply port (same as the first air supply port for each living room) near the intake port. It is possible to avoid unpleasant air conditioning disturbance due to outside air (bad temperature distribution).

  In addition, the air supply that responds to the wind pressure of the introduced outside air can be left naturally except for air pressure control by louvers, etc. Even when the range hood is not in operation, by opening the side window of the house 1 side of the house Natural ventilation is possible. In addition, since air can be supplied through the air supply box, the filter installed in the air supply box can prevent intrusion of dust and insects in the outside air into the room. And a filter etc. can also adjust the distribution amount of the air supply to each room as a resistor of an air passage.

  In the system configuration described above, the best mode of the present invention is that the ceiling space of each room is communicated to form a global ceiling space consisting of one closed space configuration, and the starting point for introducing outside air into the ceiling of an appropriate room. An air supply box is arranged. Here, the entire ceiling space including the air supply box may be considered as an air supply chamber.

  An outside air introduction opening is formed on one surface of the air supply box, and a duct is interposed between the outside air introduction opening formed on the outer wall in the ceiling and the path is naturally opened to the outdoors.

  A first air supply port and a second air supply port are formed on the other two adjacent surfaces of the air supply box, the first air supply port is opened in the ceiling on the room side, and the second air supply port Is formed facing the outside air introduction opening so as to face the entire ceiling space, and a ceiling air supply opening is formed in each of the kitchen and other rooms except for sanitary.

  The air supply box is used as the starting point for introducing the outside air, and the air is supplied to each room having the entire ceiling space as the air passage in response to the suction load by the operation of the existing ventilation fan or the wind pressure of the introduced outside air. I have to.

  Here, air control means including a louver and / or a filter is provided in the first air supply port of the air supply box and the ceiling air supply port formed in each chamber. In some cases, the second air supply port of the air supply box may be configured to provide the same air control means and adjust the air volume cooperatively.

  The air supply box is installed in the ceiling of the living room (living room / dining room). In this case, it is preferable to arrange the first air supply port in the vicinity of the suction port of the wall-mounted room air conditioner so that the air conditioning is not disturbed by the air supply.

  An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

  FIG. 1 is a plan view (plan plan) of a house (partitioned house) to which the embodiment system is applied.

  FIG. 2 is also an LR visual elevation (elevation plan).

  FIG. 3 is an LK perspective view (elevation plan) showing utilities of the living room (L) and kitchen (K).

  As shown in FIGS. 1 and 2, the outside air is supplied from the outside air inlet (2) through the flexible duct (3) by suction of a ventilation fan (51; 71) that performs forced exhaust such as a range hood or ceiling fan. Part of the outside air introduced into the air box (4) is blown out from the ceiling air inlet (20) of the kitchen (5) through the filter (44) through the ceiling (S) and mixed with the room air After that, it is sucked into the ventilation fan (51) and exhausted to the outside through the exhaust duct (existing). Therefore, when the ventilation fan (51; 71) is rotating, the air is supplied by the suction load. The toilet (6) and the bathroom (7) are not provided with a ceiling air supply port, so the air supply by the suction of the ventilation fan (71) is inflow from the door louver or undercut.

  On the other hand, the remaining introduced outside air (part of) is the air supply from the ceiling air supply port (20) (including the first air supply port 41) provided in the room (L; 8) other than the above, By providing in the vicinity of the air inlet of the air conditioner, the temperature-controlled air supply becomes possible.

  Further, it is also characteristic that natural air supply is performed in response to the wind pressure of the introduced outside air without depending on such a suction load. This is because the outside air inlet (2) is naturally open.

  Next, the air supply box (4) will be described below.

  As shown in FIG. 4 and FIG. 5, the air supply box (4) includes a box (4), a filter (44), an outside air introduction opening (43), and a first air supply port. (41) and a second air supply port (42), and is fixed by a ceiling suspension member (40).

  The first air supply port (41) is disposed on the side of the room, and is formed by punching holes in the plane of two slide shutters (13; 13) slidably provided on the frame (11) ( 14... 14) [element of the first air supply port 41], and the louver (12) is rotatably supported by the frame (11) on the lower side of the chamber.

  The second air supply port (42) is formed to face the outside air introduction opening (43) and is disposed facing the entire ceiling space (S).

  Further, a filter (44) is interposed between the second air supply port (42) and the outside air introduction opening (43) in the box (4) to form the outside air introduction opening (43). The second air supply port (42) is inclined from the lower side of the surface so as to be detachable in a diagonal direction including the upper side of the box surface. It can be removed and cleaned when contaminated.

  With this configuration, a part of the introduced outside air is supplied to the room (living room L) through the long hole group (14 · 14) [element of the first air supply port 41] and the louver (12), and the remainder is The entire ceiling space (S) is supplied to the kitchen (5) and other living rooms (8) using the air passage as a wind path. Note that the air supply amount can be adjusted by manually operating the louver (12) and the slide shutter (13). For example, when a cold winter day or a small amount of air is required, the opening of the louver (12) is throttled and the long holes (14, 14) of the slide shutter (13) are closed (notch shown) 15 is used to slide one slide shutter 13) to limit the air supply amount.

  In this way, by using the air supply box (4) as a starting point for introducing outside air, the air supply / exhaust with the whole ceiling space (S) as the air passage in the living room (L), the other living room (8), the kitchen (5), etc. The system can be equipped. Preferably, by arranging the air supply box (4) in the ceiling of the living room (L), there is an advantage that the outside air is supplied to the wall-mounted room air conditioner, and ventilation is achieved with a comfortable temperature control. . Moreover, it is not necessary to provide a ventilation port in the outer wall under the ceiling of the room such as a waist wall, and there is an advantage that restrictions on arrangement of furniture and the like can be released. Further, by adding a slide shutter (13) shown in FIG. 5 or a structure for installing a filter to the second air inlet (42) of the air supply box, the first air inlet and the second air inlet are provided. It is possible to adjust and change the amount of air supplied, or to adjust the remaining introduced outside air amount from the second air supply port.

  Construction is easy when renovating as well as new construction, and it contributes to improvement of facilities and planning systems reflecting the advantages of spacing and other ductless, so it can be expected to contribute to technological innovation in this field.
