Description

[Detailed Description of the Invention] The present invention relates to a pour-in type bath that does not have a bath pot for turning water into hot water.

In apartment complexes, large condominiums, and other housing complexes that are currently popular, there are many unit bath types that are built into a toilet with a bath, washroom, etc., or where the wall and bathtub are integrated. Most of them are of the so-called pour-in type, in which hot water is poured from elsewhere without a kettle.

On the other hand, once heated, the water in the bathtub cools down over time and must be reheated before bathing.

In a bathtub structure in which a balance pot or an external heating pot is attached to the bathtub, if the temperature of the water gets too low, simply light the pot again and the cold water will circulate between the bathtub and the bath pot. It can be heated in a short time.

However, with the above-mentioned water-adding type baths, the only way to heat the bath is to pour in hot water, which takes time to heat up the bathtub, and if there is a lot of water left over, the plug must be removed and the water must be poured out.

Nowadays, when water resources in urban areas are being depleted, this is a huge resource cost, and it also imposes a burden on users in the form of skyrocketing water rates. Even if you install a balance pot or external heating type bath pot in a hot water bath, this type of bath pot requires the ability to generate a large amount of heat, so it is large and requires a considerable amount of heat. Since installation space is required, the installation location is limited.

In other words, the installation conditions for bathtubs are that they must be easy to inspect and do not get in the way, so bathtubs that generate a large amount of heat are often installed outdoors. This type of bath kettle cannot be installed.

By the way, toilets and changing rooms are often installed in the room next to the bathroom, and because toilets and changing rooms are used temporarily, they usually do not have their own heating equipment.
In winter, when using it, it is necessary to temporarily withstand the cold.

The purpose of the present invention is to eliminate the above-mentioned inconveniences, to heat the cold water in a short time and with simple operation, without wasting hot water, and without getting in the way.
To provide a hot water bath that is easy to inspect and can heat an adjacent room.

However, according to the present invention, the purpose of this lever is to position the electric heater for reheating connected to the bathtub at a location outside the wall forming the unit bath and close to the partition wall between the bathroom and the adjacent room. This is achieved by providing air circulation holes and inspection holes in the lower part of the partition wall facing the electric heater.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a longitudinal sectional side view showing an embodiment of the bath of the present invention, and FIG. 2 is a lateral plan view of the same, showing an example of a unit bath type.

In the figure, 1 is a bathtub and this is a wall 2 that forms a bathroom 2.
It is integrated with a and manufactured in a factory.

The bathtub 1 is of a hot water type and is used by storing hot water therein from a hot water pouring faucet 3 which communicates with a separate water heater or a hot water storage tank.

Various hot water sources can be used depending on the structure of the equipment, such as a central gas hot water supply system, solar thermal energy, or a water heater that uses late-night electricity.

An electric heater 4 is connected to the bathtub 1, and this electric heater 4 communicates with the inside of the bathtub 1 through pouring and pouring pipes 5, 6 like a general gas bath pot, etc. The hot water taken in from the bathtub 1 through the injection pipe 5 is heated by a heater and sent out from the pouring pipe 6. However, the heater 4 is only for reheating, and does not need to have the ability to turn water into hot water, and may be a small one with a low heat output.

Furthermore, the electric heater 4 not only heats the hot water, but also emits heat to the outside to warm the surrounding air.

Further, the electric heater 4 is placed outside the wall 2a forming the unit bath so that the water in the bathroom 2 does not come into contact with it.

In Figure 1, 7 is an example of a toilet in an adjacent room.The toilet 7 is provided adjacent to the bathroom 2, and the bathroom 2 and the toilet 7 are connected to each other.
The electric heater 4 is located at a location close to the partition wall 8 at the boundary between the two.

At the lower part of the partition wall 8 facing the electric heater 4, an air circulation hole and an inspection hole are provided. As this air circulation hole and inspection hole, the corresponding part should be 10mm wide.
By opening the door 9, maintenance and inspection of the electric heater 4 can be performed from the toilet 7 side.
Air heated by the heat emitted by the electric heater 4 is guided to the toilet 7 through the toilet 7 for heating.

Although the above embodiment has been described with reference to the case where the bathtub 1 is a unit bath, the bathtub 1 is not necessarily limited to this, and in addition to the toilet 7, a dressing room or the like may be provided in the adjacent room.

As mentioned above, the hot water bath of this invention is
The bathtub is equipped with an electric heater for reheating, so when the hot water has cooled down, the heater can be used to quickly heat the bathtub. This eliminates the need to waste water by throwing away leftover water.

Furthermore, the above-mentioned heater only needs to be capable of reheating, and it is sufficient that it is small and consumes little power, so that the running cost does not increase.

Moreover, since the heater is for reheating, it is small and requires less installation space. As a result, it can be placed outside the wall that forms the unit bath, close to the partition wall between the bathroom and the next room, and does not get in the way like it would if it were installed inside the bathroom. It is safe because there is no electricity, so it is less likely to break down and there is no need to worry about electrical leakage. Moreover, there are air circulation holes and inspection holes in the lower part of the partition wall facing the electric heater, so maintenance and inspection can be easily carried out from the next room. Air flows into adjacent rooms such as the toilet and provides heating.

In addition, since it uses electricity as an energy source, it is suitable for modern housing complexes that do not use gas at all due to fear of explosions.
