Japanese Patent Laid-Open No. 11-182872 JP 11-193936 A Registered Utility Model No. 3075469

  As described above, a system is known in which a predetermined foundation is built so that the underfloor space has a heat insulation structure, the entire house is constructed with high heat insulation and high airtightness, and the entire house is heated with the warm air in the underfloor space where the heating device is arranged. However, in the specific means, there are various technical problems in terms of energy saving and construction cost.

  For example, in the relationship between ventilation and a heating device, only the air heating means in the underfloor sealed space is disclosed in the heating device section described in Patent Document 1, and no indoor ventilation is disclosed. In the heating systems described in Patent Documents 2 and 3, outside air is taken in, heated (heat exchange), and discharged from the ceiling part of the uppermost room, while the heating device is operated (usually 24 hours). Operation), outdoor air that is always cool air is introduced, and indoor air that is warm air is released, which is not necessarily superior in energy efficiency of heating.

  Further, the warm air supply to the living room is made as a blow-out from the micro holes on the floor surface (Patent Document 1), and a special floor material must be employed, which causes an increase in construction cost. When a predetermined outlet is formed on the floor (Patent Documents 2 and 3), the location cannot be used as a living room floor, and it is difficult to use the living room, such as dropping small items.

  Accordingly, the present invention provides a novel heating system that combines the installation structure of the heating device, the ventilation system, and the warm air supply means to the living room, is excellent in thermal efficiency (energy efficiency of heating operation), and can be used as usual in the living room. Proposed.

  A heating system for a wooden house according to the present invention is a highly insulated and highly air-tight space by the outside heat insulation of the entire house on the foundation where the underfloor space has a heat-insulated and sealed structure with respect to the outside space, and the underfloor space and the space in the wall surface of the room, and Building a ceiling and shed space in a communicating state and connecting a hot air blowing type heating device connected to an outdoor boiler so that the blowing part is located in the under floor space in the floor opening provided in a predetermined place of an appropriate room In a semi-exposed state, a gallery portion is provided below the wall surface of each living room and communicates with the space in the wall surface. In addition, an intake of an exhaust duct connected to a forced exhaust portion provided on the ceiling of each living room so that operation can be controlled. An opening is provided, and an outside air introduction part having an opening / closing mechanism is provided at an appropriate location on the outer wall.

  Thus, when the heating device is operated, warm air is blown into the underfloor space, and when the underfloor space is warmed, the first floor room is heated by the floor heating effect, and the underfloor warm air passes through the wall and rises. When warm air reaches the floor ceiling (under the second floor), the second-floor room is heated by the floor heating effect. At the same time, the warm air in the wall enters the room from the garage of each room and the room is heated. In particular, since the heating device is installed in a semi-exposed state with respect to the floor, air in the space above the floor is also drawn under the floor when warm air is blown out, and as a result, convection of warm air is realized. Heating is performed in a state where a certain amount of outside air is not taken in, and the heating efficiency is improved. Further, ventilation is performed by operating the forced exhaust section.When indoor air is released to the outside, outside air is introduced from the outside air introduction section into the wall space along the outer wall by the pressure difference inside and outside, and mixed with warm air. Will flow into each room.

  In addition, the present invention (Claim 2) particularly has an installation opening of the heating device disposed in a corner of a living room, and an upper portion of the opening serves as a shelf that can be used as a TV stand. Living room air with many doors and doors opened frequently is sent out under the floor, which promotes warm air convection throughout the house.

  Further, according to the present invention (Claim 3), the warm air flow generated by the blowing of the heating device is made to collide with the fabric foundation rising portion so that the temperature distribution of the underfloor warm air is increased under the desired living room. Thus, it is possible to selectively set the living room where the room temperature is desired to be kept high.

  The present invention is configured as described above, and heating operation is performed in a non-ventilated state (a state in which cold outside air is not taken in), and air in the floor space (room space) is blown under the floor, so that warm convection of the entire house is performed. Effective heating is realized. In addition, indoor ventilation is performed only when necessary, and a simple forced ventilation device is sufficient, and the installation cost of the heating system other than that for constructing a normal highly insulated and airtight housing is low.

  Next, an embodiment of the present invention will be described. The building in which the present invention is implemented is suitable for a highly airtight and highly insulated wooden house by a frame construction method. In addition, even if it is a house of a framed wall construction method, this invention can be implemented especially by constructing | assembling so that a ventilation path may be formed in the space in a wall.

  In the following, explanation will be made by taking a house of a frame construction method as an example. The foundation 1 of the building is basically the same as the previous foundation, but the floor lower surface portion (which may be a solid foundation) and the lower floor side of the fabric foundation 1 are covered with a heat insulating plate 2 made of foamed resin. The outer wall portion 3 is formed by forming a hermetic heat insulating structure between the pillars or between the pillars with a foamed resin heat insulating plate, and further sticking a predetermined outer wall material, a sealing plate or the like.

  Further, the roof 4 is formed in a heat-insulated and sealed structure using a member in which a foamed resin plate is attached to the base plate (between rafters), and the outer wall portion 3 and the continuous portion are sealed.

  Therefore, the whole house is a highly insulated and airtight house as a sealed space cut off from the outside air. However, a forced exhaust mechanism that installs an exhaust duct on the stove is incorporated in the kitchen, and a forced exhaust mechanism is also incorporated in the bathroom.

  In the indoor construction such as a living room, the entire underfloor space A is in a communicating state with respect to the cloth foundation 1a part under the floor, and the cloth foundation 1a is adapted to the state of the warm air flow in the underfloor space described later and the purpose of use of the first floor living room. Determine the rise range (considering the combination of foundation and bundle at the design stage).

  The first-floor room 5 and the second-floor room 6 are constructed so as to have an air passage (space in the wall) B between the outer wall portion 3 and the partition wall between adjacent living rooms, and further, the second-floor space C and the shed The back space D is also communicated with the in-wall space B.

  The heating mechanism 7 includes a warm air blowing type heating device 72 connected to an outdoor boiler 71, and the heating device 72 is placed in a floor space A in a floor surface opening 73 provided at a corner of the living room 5a. It is installed in a semi-exposed state so that warm air is blown out, and the upper part of the opening 73 is a shelf 74 that can be used as a TV stand. Further, a louver 75 that communicates with the space in the wall surface is provided at an appropriate location on the wall surface of each of the living rooms 5 and 6 (determined in consideration of the place where the furniture is placed below the wall surface).

  The ventilation mechanism 8 is installed in the attic space D and exhausts to the outside air, a forced exhaust part 82 that can be operated and installed in the same place, and intake air provided in the ceilings of the living rooms 5 and 6. Outside air provided with an exhaust mechanism composed of an outlet 83 and an exhaust duct 84 connecting the forced exhaust part 82, and further provided with an opening / closing mechanism (forced opening / closing or automatic opening / closing by differential pressure) provided at an appropriate location on the outer wall 3 The introduction part 85 and the air supply part 86 provided on the wall surface of the predetermined living room 5a are provided.

  Thus, when the outdoor boiler 71 and the heating device 72 are operated, the warm air a is blown into the underfloor space A, the underfloor space A is heated, and the first floor room 5 is heated by the floor heating effect.

  In particular, when the warm air flow a from the heating device 72 is caused to collide with the cloth foundation rising portion 1a in the underfloor space A, the flow of the warm air a changes due to the collision, and particularly when the warm air flows collide with each other, the hot air flows easily. Since the temperature of the staying space becomes higher than that of the other spaces, the arrangement of the foundation is determined at the house design stage when the room temperature is to be kept high as in the elderly room.

  The warm air flow a blown out into the underfloor space A passes through the wall surface space B and enters the second floor underfloor space C, and the second floor room is heated by the floor heating effect.

  Furthermore, the living rooms 5 and 6 on the upper and lower floors have warm air b entering the living rooms 5 and 6 from the louver 75 provided on the wall surface, thereby producing a heating effect for maintaining the room temperature.

  In the present invention, since the heating device 72 is installed on the floor in a semi-exposed state, when the warm air flow a is blown out, the air c in the floor space is also drawn under the floor, resulting in the convection of the warm air in the entire house. Is realized. In particular, by installing the heating device 72 in the living room 5a in which air circulation with other living spaces is easily performed by opening and closing the door, the above-described warm convection of the entire house is efficiently performed, and at the same time in the living room The amount of warm air intrusion from the garage portion 75 increases, and the living room where the family often gathers is heated more quickly than in other living rooms.

  For indoor air ventilation, when the forced exhaust section 82 is operated, the indoor air is exhausted from the living rooms 5 and 6 through the exhaust duct 84 to the outside. At the same time, fresh outside air d is introduced from the outside air introduction section 85 into the wall surface space B, and ventilation is performed.

  The introduced outside air d is mixed with the warm air flow a in the wall surface space, and is introduced from the louver 75 into each of the rooms 5 and 6. In particular, in the living room 5a where people gather, an air supply portion 86 is provided on the wall surface so that the ventilation air can be quickly introduced from the inner wall surface B where the introduced outside air d is mixed.

  With the above configuration, it is possible to provide a heating system that is excellent in energy efficiency and can reduce heating costs by realizing warm air convection in the whole house in a non-ventilated state where cold outside air is blocked.
