Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention prevents dew condensation in the north side room in winter by sufficiently ventilating the outside air of the building room, and also uses the bathroom as a drying room. The purpose is to obtain an indoor ventilation system that takes into consideration.

[Background technology]

In a reinforced concrete apartment house, the indoor airtightness is high, so in the north side room there is condensation and mold in the winter, and in extreme cases it may become impossible to open and close the windows due to condensation. . Generally, a small opening that can be opened and closed is provided in the window portion and its periphery, but when it is opened, the cold and warm outside air directly flows in, and it is not used sufficiently in practice.

In view of the above facts, the present invention has an object to obtain an indoor ventilator capable of preventing condensation and mold in the north side room by utilizing the heat sources of the south side room and the bathroom.

[Outline of Invention]

The present invention is directed to a suction part to which the exhaust air of the south side chamber and the bathroom is selectively guided, an adjusting part having one end connected to the suction part and having a dehumidifying filter and a heater, and one end connected to the adjusting part to the bathroom and the north side. It is characterized in that it has a delivery section for selectively delivering air to the chamber, and an air blowing means for delivering air from the suction section to the delivery section.

Therefore, in the present invention, after warm air in the south side room or bathroom is dehumidified by the dehumidifying filter in winter, it can be heated by the heater and sent to the north side room as needed. As a result, it is possible to limit the generation of dew condensation and mold in the north side chamber without operating the heating device or the like. The bathroom can also be used as a drying room by circulating the air in the bathroom with a dehumidifying filter and a heater.

If the adjusting part equipped with the dehumidifying filter and the heater is provided in the housing together with the suction part and the sending part, the ventilation device can be configured as a unit, and the installation is extremely simple.

Example of Invention

FIG. 1 shows a vertical sectional view of a building 10 to which the present invention is applied.

This building 10 is an apartment house made of reinforced concrete, and the north side room 12, bathroom 14, south side room 16 have partition walls 18, 20 on the same floor.
Are separated from each other.

A heater 24 that discharges combustion air through an outer wall 22 is arranged in the south chamber 16. Also, this outer wall 22 has an air conditioning ventilation fan.
16 is integrally installed and arranged in the window frame Sash.

Further, inside the void slab 28 arranged between this floor and the upper floor, a chamber (or duct) 30 is provided on the ceiling of the south side chamber 16 and communicates with a part of the south side chamber 16 through the opening 30A. ing. The chamber 30 can exhaust the inside of the chamber 30 through a ventilation port 32 provided in the outer wall 22.

Similarly, a part of the chamber 36 arranged on the ceiling of the north side chamber 12 is also communicated with the north side chamber 12 through the opening 36A.

On the other hand, in the upper part of the bathroom 14, the ventilation device shown in FIG.
40 are provided. The ventilation device 40 is in a state in which a partition wall 44 is provided in the housing 42 and basically forms a pair of left and right chambers 46 and 48.

The chamber 46 has a lower part as an intake part, and is selectively communicated by an intake side damper 50 with an exhaust port 52 provided in a ceiling part of the bathroom 14 and a duct 54 communicating with the chamber 30. The louver 56 is arranged so that the exhaust port 52 faces the bathroom 14.

Further, the lower part of the chamber 48 is a sending part, and an exhaust side damper 60 is arranged so that a sending port 62 provided in the ceiling part of the bathroom 14 and a duct 64 communicating with the chamber 36 can be selectively opened and closed. ing. The louver 58 faces the bathroom 14 at the outlet 62.
Is installed.

A dehumidifying filter 66 is arranged in the chamber 46 above the intake side damper 50, and a heater 68 is arranged in the chamber 48 above the exhaust side damper 60 to form an adjusting section together with the dehumidifying filter 66. In addition, a fan 70 is attached to the partition wall 44 from the chamber 46.
Air can be pumped to 48.

A duct 72 is connected to an intermediate portion of the duct 64, and a tip portion thereof is open to the outside of the building. This duct 72 and duct 64
A branch damper 74 is arranged at a connecting portion between and, and the air sent from the chamber 48 is selectively distributed to the duct 64 and the duct 72.

The dehumidifying filter 66, the heater 68, the fan 70, and the dampers are connected to a control means (not shown) so that they can be controlled manually or automatically by an operation panel arranged in any room. ing. This control device receives the signal from the dew condensation sensor 76 provided in the north chamber 12
It may be activated automatically when condensation occurs on 12. Further, this control device may be provided in the south side chamber 16 and operated in conjunction with a ventilation sensor 27 for automatically operating the air conditioning fan 26 to ventilate the south side chamber under predetermined conditions.

 Next, the operation of this embodiment will be described.

The south side room 16 is heated by the heater 24 in winter, but when indoor air is polluted, the ventilation sensor 27 automatically detects this and operates the air conditioning fan 26 to ventilate the south side room 16.
In addition, the ventilation port 32 uses the void slab 28 to exhaust gas from the kitchen in the room.

When the bathroom 14 is exhausted, the intake side damper 50 shown in FIG. 2 is connected in solid line to communicate with the bathroom 14 and the chamber 46, and the exhaust side damper 60 is connected in communication to communicate with the chamber 48 and duct 64. The branch damper 74 keeps the duct 72
When the air is communicated with the 48, the air in the bathroom 14 is discharged to the outside through the chambers 46, 48 and the branch damper 74 by the rotation of the fan 70. In this case, the dehumidifying filter 66 and the heater 68 should not be operated.

When dew condensation occurs in the north side chamber 12, the warm air in the south side chamber 16 is sent to the north side chamber 12. Therefore, the intake-side damper 50 and the exhaust-side damper 60 are in the state of broken lines in FIG.
48, the warm air in the south side chamber 16 is sent to the north side chamber 12 through the duct 64. In this case, it is preferable that the fan 70 is operated and the dehumidification filter 66 and the heater 68 are operated to dehumidify or heat the air in the south chamber 16 and then send the air to the north chamber 12. If necessary, the air in the bathroom 14 may be dehumidified or heated and then sent to the north side chamber 12.

When the inside of the bathroom 14 is used as a drying chamber, the intake side damper 50 and the exhaust side damper 60 are set to the solid line state, and the fan 70 is rotated, the air in the bathroom 14 is exhausted through the exhaust port 52, the chamber 46, the chamber 48, Since it circulates through the outlet 62, the dehumidifying filter 66, the heater
68 allows the air in the bathroom 14 to be dried to serve as a drying room for dehumidifying and drying laundry, bedding and the like.

When supplying warm air from the south side chamber 16 to the north side chamber 12,
As shown by an arrow A in the figure, the return air enters from the north side chamber 12 to the south side chamber 16 to circulate while maintaining the air conditioning balance.

[Effects of the Invention] As described above, according to the present invention, the warm air of the south chamber is sent to the north chamber as necessary, so that it is possible to suppress the formation of dew condensation and mold without providing a special heating means to the north chamber. Has excellent effect.
