Abstract

PURPOSE:To prevent a north side room from forming condensed dew in the wintertime, and to make use of a bathroom even as a drying room by sufficiently ventilating rooms in a house with the external air. CONSTITUTION:After warm air in a south side room 16 or in a bathroom 14 has been dehumidified by a dehumidifying filter 66 in the wintertime, the warm air is, if necessary, heated by a heater 68 and sent into a north side room 12. As a result, the formation of condensed dew and/or the gathering of mold in the north side room 12 can be restricted without particularly actuating a heating apparatus and the like. Further, if the air in the bathroom is circulated by means of the dehumidifying filter 66 and the heater 68, the bathroom 14 can also be used as a drying room. Consequently, the formation of condensed dew and/or the gathering of mold in a north side room 15 can be restricted without particularly actuating the heating apparatus and the like.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention prevents dew condensation in the north room in winter by sufficiently ventilating the interior of the building with outside air, and also allows the bathroom to be used as a drying room. The purpose is to obtain an indoor ventilation system that takes this into consideration.

[Background technology]

In reinforced concrete condominiums, the rooms are highly airtight, so rooms on the north side are prone to condensation and mold growth during the winter, and in particularly extreme cases, the condensation can turn into ice, making it impossible to open or close the windows. . Generally, a small opening that can be opened and closed is provided in or around the window, but when it is opened, cold and hot outside air flows directly into the window, so it is not actually used enough.

The present invention takes the above-mentioned facts into account, and aims to provide an indoor ventilation system that can prevent condensation and mold in the north room by utilizing heat sources in the south room and the bathroom.

[Summary of the invention]

The present invention provides a suction section through which exhaust air from a south room and a bathroom is selectively guided, a control section that is connected at one end to the suction section and equipped with a dehumidifying filter and a heater, and a control section that is connected to the control section at one end and is connected to the bathroom and the north side. It is characterized by having a delivery section that selectively sends air into the room, and an air blower that sends air from the suction section to the delivery section.

For this reason, in the present invention, after dehumidifying the warm air in the south room or bathroom in winter using a dehumidifying filter, it can be heated with a heater and sent to the north room, if necessary. This makes it possible to limit the occurrence of dew condensation and mold in the north room without having to specifically operate a 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 heater.

By providing the regulating section with the dehumidifying filter and the heater in the housing together with the suction section and the delivery section, the ventilator can be constructed as a unit and installation is extremely simple.

This building 10 is a reinforced concrete apartment building, and a north room 12, a bathroom 14, and a south room 16 are arranged on the same floor, separated by partition walls 18 and 20.

A heater 24 is disposed in the south chamber 16 and discharges combustion air through an outer wall 22. Further, an air conditioning ventilation fan 26 is disposed on the outer wall 22 and is integrally incorporated into the window frame.

In addition, a chamber (or duct) 30 is provided in the ceiling of the south room 16 in the void slab 23 located between this floor and the upper floor, and communicates with a part of the south room 16 through an opening 30Δ. ing. This chamber 30 is configured such that the inside of the chamber 30 can be exhausted through a ventilation port 32 provided in the outer wall 22.

Similarly, a portion of the chamber 36 disposed on the ceiling of the north chamber 12 is communicated with the north chamber 12 via the opening 36A.

On the other hand, the second part of the bathroom 14 is provided with a ventilation system 40, which is also shown in FIG. This ventilation device 40 has a partition wall 44 provided within a housing 42, and basically constitutes a pair of left and right chambers 46 and 48.

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

Further, the lower part of the chamber 48 is used as a delivery section, and an exhaust side damper 60 is arranged, so that a delivery port 62 provided in the ceiling of the bathroom 14 and a duct 64 communicating with the chamber 36 can be selectively opened and closed. ing.

A louver 58 is attached to the outlet 62 facing the bathroom 14.

A dehumidifying filter 6 is provided in the chamber 46 above the intake damper 50.
6 is disposed in the chamber 48, and a heater 68 is disposed above the exhaust damper 60 in the chamber 48, and together with the dehumidification filter 66 constitutes an adjustment section. Further, a fan 70 is attached to the partition wall 44 so that air can be pumped from the chambers 46 to 48.

Further, a duct 72 is connected to the middle part of the duct 64, and the tip part thereof is open to the outside of the building. A branch damper 74 is disposed at the connection between the duct 72 and the duct 64, and
The air sent out from 8 is selectively distributed to duct 64 and duct 72.

The dehumidifying filter 66, heater 68, fan 70, and each damper are connected to a control means (not shown), and can be manually operated using an operation panel placed in any room.
or automatically controlled. This control device may receive a signal from a dew condensation sensor 76 provided in the north room 12 and be automatically activated when dew condensation occurs in the north room 12. Further, this control device may also be linked with a ventilation sensor 27 provided in the south room 16 to operate the air conditioning ventilation fan 26 under predetermined conditions to automatically ventilate the south room.

Next, the operation of this embodiment will be explained.

The south room 16 is heated using a heater 24 in winter, but when the indoor air becomes contaminated, a ventilation sensor 27 automatically detects this and operates the air conditioning ventilation fan 26 to ventilate the south room 16. Further, the ventilation port 32 exhausts the indoor kitchen using the void slab 28.

Further, when exhausting the bathroom 14, the intake side damper 50 shown in FIG.
