Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a bathroom unit that allows daylighting in a living room.
It can be used as a second bus in condominiums and other condominiums, as well as single-family homes.

[Conventional technology]

Traditionally, ordinary households took a bath at night, and there was a strong belief that bathing was done at night to relieve the fatigue of the day, such as before going to bed. There is a tendency for young people in particular to view it as a comfortable act with no restrictions.
Taking a shower when you wake up and getting ready in the early morning sunlight is a desirable lifestyle, and there is a growing demand for comfort that combines bathing and sunlight.

In response to these demands, bathrooms, which were traditionally placed on the north side of a building, are now being placed on the sunny side of living rooms on the south side of the building, making it easier to bathe and bare in the sunlight. This allows for easy access between the bathroom and living room. In addition, in resort condominiums, etc., it is possible to make effective use of the limited occupied space by providing a bathroom on the balcony space, and in detached houses, etc., by providing a bathroom on the daylight side of the second floor bedroom, etc. Apart from the shared bathroom, it can also be used as a private bathroom.

By the way, when a bathroom and a living room are provided spatially consecutively, moisture from the bathroom may fill the living room and have an adverse effect, so it is necessary to partition the two. However, configuring the two areas as separate sections of the building structure is burdensome in terms of construction and construction costs. To solve this problem, there are small unit bathrooms that are installed on balconies on the daylighting side of buildings. When using such small, stationary bathrooms, the bathroom and living room can be separated from each other, and moisture and moisture can be removed. In addition to being able to solve problems, it is extremely easy to install as it does not require any construction work on the building other than piping.

[Problem that the invention attempts to solve]

However, when using a unit bathroom that is installed independently on a balcony, the length of the balcony protruding from the building's exterior wall is limited, so a bathroom that can fit on the balcony does not have enough interior space. , unable to achieve a comfortable bath. Also,
When going in and out between the bathroom and the living room, the person is temporarily exposed to the outside air, which is extremely inconvenient during the cold winter months. Furthermore, if such a unit bathroom is installed on a balcony, depending on the placement, it may block the windows and doors facing the balcony, which may impede access to the balcony.
There was a problem in that the lighting and ventilation were obstructed, which could impair the comfort of the living room, thus defeating the original purpose of locating the bathroom on the daylighting side.

The purpose of this invention is to install a bathroom of sufficient size and direct access to the living room on the balcony space on the daylighting side of the living room, allowing for comfortable bathing in the bathroom and providing sufficient lighting to the living room. To provide a bathroom unit capable of lighting a living room without impairing the comfort of the living room.

[Means for solving problems]

The present invention provides an overhanging portion that protrudes horizontally on the outside of the exterior wall structure of a building that partitions a living room from the outside, and that is partially formed as a balcony. A bathroom is provided that reaches into the living room, and among the walls forming this bathroom, an openable and closable door is provided on the inner wall that partitions the living room and the bathroom, and each of the inner wall and at least the outer wall facing the inner wall. A lighting section made of a light-transmitting member is provided in the bathroom, thereby constructing a bathroom unit that allows lighting into the living room.

[Effect]

In this invention, by extending the bathroom from the balcony part through the external wall structure and into the living room, the volume of the penetrating part of the external wall structure is effectively used to secure the internal spaciousness of the bathroom. At the same time, the bathroom and living room are separated by an inner wall with a door to ensure moisture resistance and direct access.Furthermore, the bathroom is separated from the living room by lighting sections provided on each of the inner wall and the opposing outer wall. The entire structure is double-glazed, so to speak, to ensure daylight into the living room, thereby achieving the above purpose.

In addition, parts of the outer wall surface 11, side wall surfaces 12, 13, top plate 14, inner wall surface 15, etc. can be replaced with other equivalent products, and each can be adjusted according to the user's preference at the time of installation. In addition to being able to select from equivalent products with different functions such as presence or absence, it is possible to correspond to a variety of buildings 1 by appropriately selecting wall materials depending on the shape of the overhanging portion 4 and the outer wall structure 3.

Furthermore, the side wall surface 12 in the opening 3A portion,
13 and the top plate 14 and the inner wall surface 15 are made adjustable, so that the bathroom unit 10 can be formed to the desired dimensions regardless of the thickness of the outer wall structure 3, and the bathtub unit 20 can be connected to the inner wall surface 15. After that, it can be easily integrated by plugging it into the opening 3A, so that construction is easy and waterproofness can be improved.

In addition, since the connecting parts of each wall of the bathroom unit 10 are waterproof sealed, it is possible to prevent the intrusion of raindrops from the outside or cold air in winter, etc.
Steam and water droplets generated in the bathroom 7 can be prevented from entering the living room 2.

Furthermore, an exhaust duct 28 provided on the top plate 14
In addition, the bathroom 7 can be ventilated through the window 12A and the door 16, and moisture leaking into the living room 2 can be ventilated through the ventilation duct 26, thereby improving the livability and moisture resistance of the building 1 including the living room 2. without damaging it.

In addition, these ventilation ducts 26 and exhaust ducts 2
8 or the lighting device 27 etc. are integrated into the bathroom unit 10, construction of peripheral equipment is easy, and together with the ease of forming the bathroom unit 10, the bathroom 7
can be installed more easily.

In addition, access to balcony 6 is restricted by doors 16 and 1.
Since this is done by passing through the bathroom 7 using the bathroom 7, it is possible to omit a window for accessing the balcony 6, etc., and it is possible to simplify processes such as waterproofing the part.

Furthermore, during renovations, the sweeping window that conventionally led to the balcony 6 can be used as the opening 3A to install the bathroom unit 10, and it is possible to eliminate most of the parts of the building 1 itself that need to be renovated, significantly reducing the construction work.
