 According to the present invention, the air flowing inside the internal duct can be warmed by the heat maintained at a high temperature in the inner space of the casing, so that the heat stored in the heat storage body can be efficiently used.

 Further, by connecting the heat storage body and the internal duct via a heat conductive member, high-temperature heat radiated from the heat storage body can be directly conducted to the internal duct.

 Furthermore, by forming the internal duct with a metal having good thermal conductivity, the heat radiated from the heat storage body can be easily conducted to the air in the internal duct, and heat loss at the time of conduction can be suppressed.

 Further, according to the heating system in which the heat storage and heating apparatus according to the present invention is provided in the underfloor space on the lowest floor of the building, the heat storage and heating apparatus can provide the room without providing a floor gallery for supplying air. The heat radiated to the underfloor space can warm at least one living room in the building through the floor or the like.

 Moreover, since the heat radiated to the space in the casing by the heat storage body can be conducted to the air flowing through the internal duct, the heat of the heat storage body can be used efficiently and the external duct connected to the internal duct. Air that has been sufficiently warmed through can be supplied to each room in the building.

 In addition, clean outside air taken from outside the building through the ventilation system is directly supplied to each room through the external duct and internal duct connected to the ventilation system without being supplied into the underfloor space. The cleanliness of the air supplied to each room can be maintained.

 Furthermore, the heat loss of the supplied air can be reduced by forming the heat insulating layer on the inner periphery of the external duct connected to the living room separated by a predetermined distance from the underfloor space.

 Accordingly, the fins 13c,... Can conduct heat stored in the heat storage material 13b such as bricks directly to the internal connection duct 12 through the fins 13c,.

 On the other hand, as shown in FIG. 3, the external connection duct 11 has a base portion 11a made of synthetic resin or the like and a heat insulating layer 11b formed on the inner periphery of the base portion 11a.

 On the other hand, the internal connection duct 12 is made of a metal material having good thermal conductivity.

 Next, the effect | action of the thermal storage heating apparatus which concerns on embodiment of this invention is demonstrated.

 First, when the occupant operates the heat storage and heating device 5 by operating a remote controller or the like, the ventilation device 6 takes in outside air from the outside of the building through the intake duct 8 and supplies air to the heat storage and heating device 5 through the external connection duct 11.

 And the heat storage heating apparatus 5 dissipates the heat stored in the heat storage material 13b in the late night zone into the casing 13 of the heat storage heating apparatus 5 and conducts the heat to the internal connection duct 12, and each fin 13c,. The heat stored in the heat storage material 13b is directly conducted to the internal connection duct 12 through the heat transfer material.

 The air heated in the internal connection duct 12 is supplied to the floors of the living rooms A, C and D through the external connection duct 11 connected to the internal connection duct 12 through the through holes 13d and 13d. Air is supplied from the mouth 14.

 At this time, the temperature of each part of the heat storage heating device 5 is, for example, about 600 ° C for the heat storage material 13b, about 600 ° C for the space inside the casing 13, about 80 ° C for the surface of the casing 13, and the temperature of the underfloor space 4 is It becomes about 30 ° C.

 Therefore, the heat radiated to the underfloor space 4 by the heat storage and heating device 5 is conducted through the floor 2 and under the floors of the living rooms C and D without providing a floor gallery for supplying air into each living room. Each room A, C, D in the building and each shared space B1, B2 can be warmed.

 Moreover, since the high-temperature heat radiated to the space in the casing 13 by the heat storage material 13b of the heat storage heating device 5 can be directly conducted to the air flowing through the internal connection duct 12, the heat of the heat storage body can be used efficiently. In addition, the air sufficiently heated through the external connection duct 11 connected to the internal connection duct 12 can be supplied to the living rooms A, C, and D in the building.

 In addition, since the heat storage and heating device 5 stores heat during a time period when the electricity rate is low at midnight and gradually dissipates heat other than at midnight, an economical operation is possible.

 Further, clean outside air taken from outside the building by the ventilation device 6 through the intake duct 8 is not supplied into the underfloor space 4 and passes through the external connection duct 11 and the internal connection duct 12 connected to the ventilation device 6. Since air is directly supplied to each of the living rooms A, C, and D, the cleanliness of the air supplied to each of the living rooms can be maintained without being contaminated by dust or the like in the underfloor space 4.

 Moreover, the heat loss of the supplied air can be reduced by forming the heat insulation layer 11b in the inner periphery of the external connection duct 11 connected to each of the living rooms A, C, and D.

 After that, the air supplied to each room A, C, D circulates in each room to raise the room temperature, and the upper end and wall of each door A1, C1, D1 of each room A, C, D The air is exhausted from the exhaust port 15 provided between the two to the outside of the living room.

 The air exhausted outside the room warms both the spaces through the shared space B1 and the shared space B2, and the indoor intake duct 9 via the filter 10 installed on the floor surface of the floor 2 of the shared space B1. And is exhausted from the exhaust duct 7 to the outside of the building by the ventilation device 6.

 In addition, even when the heat storage and heating device 5 is not in operation, the ventilation device 6 can be operated. At this time, the ventilation device 6 has been discharged from each of the rooms A, C, and D and moved to the shared space B1. Air is sucked from the indoor intake duct 9 and the sucked air is exhausted outside the building through the exhaust duct 7.

 And since the outside air taken in from the outside of the building by the ventilation device 6 can be supplied to the living rooms A, C, D through the external connection duct 11 without being heated by the heat storage and heating device 5, the temperature in each living room Even if the temperature rises too much, temperature control and ventilation can be performed.

 The embodiment of the present invention has been described in detail above with reference to the drawings. However, the specific configuration is not limited to this embodiment, and design changes that do not depart from the gist of the present invention are not limited to this embodiment. Included in the invention.

 For example, the heat storage and heating device 5 according to the above embodiment shows a method of storing the resistance heat generated by energizing the electric wires in the heat storage material 13b, but is not limited to this, hot water boiled in a boiler or You may use the system of accumulating electrically heated hot water in concrete.

 Moreover, although the internal connection duct 12 and the heat storage material 13b which concern on the said embodiment are connected via each fin 13c, ..., it is not limited to this, The air in the casing 13 is supplied. When heat is sufficiently conducted through the fins 13c, it is not necessary to connect them through the fins 13c.
