Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation structure around a unit bath which constitutes a bathroom of a house, and in particular, condensation, mold, etc. generated around the unit bath in a highly airtight house.
Ventilation structure that prevents corrosion.

[0002]

2. Description of the Related Art In recent years, houses in Japan are often made airtight for the purpose of energy saving. Generally, a highly airtight house has 6
A heat insulating material layer is provided on all of the face pieces to make them airtight, and planned ventilation (natural ventilation or forced ventilation) is continuously performed for 24 hours continuously in the living space and the outer wall space to prevent the formation of condensation and mold. .

Not only in highly airtight houses, but in recent houses, bathrooms are often composed of unit baths. In general, a unit bath has a bathtub and a washing room integrally formed of fiber reinforced plastic, etc., and is installed by being supported on a concrete floor by a plurality of legs. Spaces are formed between the periphery of the unit bath and the outer wall filled with the heat insulating material, and between the bottom and the floor. But for airtight houses, these spaces are usually designed as part or extension of the living space,
Out of range of planned ventilation system. As a result, these spaces become closed spaces that do not have ventilation, causing dew condensation, mold, etc., which causes corrosion of surrounding structural members.

[0004]

In order to avoid such a problem, it is possible to remove these spaces.
However, the storage space of the unit bath must be made larger than the unit bath in advance, and it is practically impossible to eliminate the space between the outer periphery of the unit bath and the wall surface.
Then, stagnation of air occurs in the space, causing a problem of corroding structural members and the like. Then, this invention makes it a subject to solve such a problem, and it aims at providing the ventilation structure around the new unit bath for that.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic plan view showing an example of a highly airtight house to which the ventilation structure of the present invention is applied, and FIG. 2 is a sectional view taken along line AA in FIG. In these figures, a highly airtight house 1 has a living space 2 including an entrance, a washroom 3,
It is divided into a bathroom 4 constituted by a unit bath, and the living space 2, the washroom 3 and the bathroom 4 are surrounded by an outer wall 5. Inside the outer wall 5, the washroom 3 and the bathroom 4 integrally form an independent airtight space 6 with respect to the living space 2. A washroom 3 is provided between the airtight space 6 and the living space 2.
The airtight door 7 on the side of the living space provided at the front allows the vehicle to pass through. By thus forming the bathroom 4 constituted by the unit bath as the airtight space 6 integrally independent of the washroom 3, it is not necessary to consider the airtightness of the bathroom 4 at the boundary portion of the washroom 3. There is an advantage that the design of the airtight space and the maintenance of the house can be facilitated.

FIG. 3 is an elevational view showing a more specific structure of the washroom 3 and the bathroom 4, and FIG. 4 is a plan view of FIG. In these figures, the washroom 3 and the bathroom 4 form an independent airtight space 6, and the partition walls 8 of the washroom 3 and the living space 2 are provided with airtight doors 7, and the washroom including the partition wall 8 An airtight sheet layer 10 is formed on the side wall of the place 3 and the inside of the ceiling wall 9. As the airtight sheet layer 10, for example, a sheet material such as a trade name Dan Sheets (Ube Confidential Co., Ltd.) can be formed by sticking. The bathroom 4 is composed of a unit bath 11, and the unit bath 11 is supported by a plurality of legs 13 on an underfloor foundation 12 on the first floor. An inspection port 14 is provided on the ceiling of the unit bath 11, and an exhaust unit 15 is provided on the side facing the outer wall 5. Further, a bathroom door 17 is provided on the partition wall 16 of the unit bath 11 and the washroom 3.

An air supply unit 18 is provided above the side wall of the washroom 3.
Is provided, and part of the external air supplied from the air supply unit 18 passes through the lower gap of the bathroom door 17 as shown by the arrow (FIG. 3) to the outside from the exhaust unit 15 provided in the unit bath 11. It is evacuated, thereby providing internal ventilation of the washroom 3 and bathroom 4. Therefore, the unit bath 1 is configured by the exhaust unit 15 and the air supply unit 18.
A ventilation device 27 is configured to ventilate the inside of the washroom 1 and the inside of the washroom 3 in common. Further, the floor 19 of the washroom 3 is provided with a communication portion 20 such as an exhaust gallery, and a part of the external air supplied from the air supply unit 18 passes through the communication portion 20 and is indicated by an arrow (FIG. 3). It is exhausted to the underfloor 21.

On the other hand, outside the unit bus 11,
A space between the ceiling portion and the ceiling wall (floor portion on the second floor) 9, a space between the side portion and the outer wall 5, a space between the side portion and the partition walls 8 and 16, a floor portion and a foundation portion 12 under the floor. The spaces communicate with each other, in which the space between the floor of the unit bath 11 and the foundation 12,
That is, the underfloor 22 of the unit bath 11 communicates with the underfloor 21 of the washroom 3. The underfloor 22 of the unit bath 11 and the underfloor 21 of the washroom 3 are isolated (closed) from the surroundings by an underfloor partition wall 23.

Therefore, these spaces form one independent airtight space 24, and the airtight space 24 and the outer wall 5 are formed.
(Specifically, an exhaust unit 25 provided on the outer wall 5 facing the upper part of the unit bath 11 and a communication section 20 provided on the floor 19 of the washroom 3 constitute a planned ventilation space 26 with forced ventilation. To be done. That is, by operating the exhaust unit 25, the air taken in from the communicating portion 20 of the floor 19 of the washroom 3 is exhausted to the outside from the exhaust unit 25 through the airtight space 24, thereby forcing the airtight space 24. Be ventilated. Due to the planned ventilation space 26 with such forced ventilation, the surroundings of the unit bath 11 are quickly and efficiently ventilated independently of the planned ventilation of the entire house 1, so that the occurrence of condensation and mold around the unit bath 11 is prevented. Can be prevented.

The exhaust unit 25 is mounted from the outside of the house 1 to facilitate maintenance and replacement. Further, instead of providing the communication part 20 in the washroom 3, an intake port for supplying outside air can be provided in the lower portion of the outer wall 5. In that case, it is desirable to provide a filter that can be detached from the outside at the intake port. On the other hand, in the case of providing the planned ventilation space 26 by natural ventilation, an exhaust port is provided in that part instead of the exhaust unit 25, and the intake port is provided with the communication part 20 in the floor part 19 of the washroom 3 or the outer wall. An intake port through which the outside air passes is provided in the lower part of 5. Even in that case, it is desirable to provide a filter that can be attached and removed from the outside at the exhaust port and the intake port.
