TECHNICAL FIELD The present invention relates to an optional bath system used for bathing a care recipient or the like who has difficulty in bathing.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a bathtub installed as needed in addition to a bathtub fixedly installed in a bathroom for taking a bath of a cared person or a fixed but simple bathtub is an air-expandable type, a prefabricated type. And various types such as a retractable type are known (see, for example, JP-A-9-308665, JP-A-9-308666, and Registration No. 3043917). In these devices, there is no equipment for pouring and discharging the bathtub, but a separate pump is prepared and pouring is performed by this pump.
[0003]
On the other hand, a general bathtub and a special door-opening / closing bathtub for medical use are both installed in the same bathroom such as a hospital facility, and the hot water stored in the general bathtub is transferred to the door-opening / closing bathtub. There is also a known one (see, for example, JP-A-9-308667). In this apparatus, one pipe is previously installed in which one end is immersed in the hot water of the hot tub and the other end is communicated with the openable tub, and a pump is interposed in the middle of the pipe. Let me. Two pipes for hot water supply and drainage passing through the pump are provided in the middle of this pipe, and a three-way switching valve for drainage is provided.
[0004]
[Problems to be solved by the invention]
By the way, in the bathing of the protector as described above, when it is desired to bathe a newborn in a warm living room instead of a cold bath in winter, instead of bathing only a newborn using a very small bathtub for a newborn. Therefore, there is a demand that parents want to take a bath with the newborn baby. In addition, even when the care receiver is bathed as described above, there is a demand that the care receiver should take a bath in a warmed room in order to reduce a physical burden due to a difference in ambient temperature between the room and the bathroom in winter. . When there is such a demand, it is also conceivable to use the above-mentioned conventional bathtub or the like which is installed as needed.
[0005]
However, in the conventional bathtub or the like that is installed at any time, heavy labor such as transporting hot and cold water many times with a bucket or the like is required for pouring and discharging the bathtub. Here, if a commercially available hose and a commercially available electric pump are prepared, it is possible to pour water from some kind of hot water storage tank and drain the water by reversing the direction of the pump, but the temperature of the hot water dropped during bathing In this case, the hot water that has been filled with water has to be drained out in an appropriate amount, and new hot water having to be hot has to be transported by a bucket or the like to additionally supply the hot water, which requires heavy labor. In addition, after bathing, it is necessary to extend the hose to a considerably far drain to discharge a relatively large amount of hot water.
[0006]
On the other hand, although it is conceivable to install the above-mentioned piping in a general household as in the case of the conventional door-opening tub installed in a hospital facility or the like, even in this case, hot water is stored in a hot water tub (general tub). Since the hot water is simply transferred, when the temperature of the hot water in the open / close tub decreases, the hot water is further stored in the hot tub, and the hot water is additionally supplied to the open / close tub. You need to take action. Alternatively, heavy labor is required in which hot water is carried by a bucket or the like and added. In particular, if a bathtub is installed in a room other than the bathroom of a general household at any time, the temperature of the hot water cannot be reduced due to heat radiation to the large space. Adjusting the temperature is an essential task. In addition, since it is necessary to interpose equipment such as a pump and a large number of three-way switching valves in the middle of the piping in advance, it is difficult to arrange such piping particularly in general homes, etc. Become.
[0007]
The present invention has been made in view of such circumstances, and its purpose is to pouring water into a bathtub that is installed as needed, to reheat the poured hot water, and to drain the hot water.

Further, a three-way switching valve may be interposed at the branch point between the circulation pipe and the pair of branch pipes in the same manner as described in the first aspect. In the case of the third aspect of the present invention, the three-way switching valve is not always necessary because the outlets provided at the respective ends of the pair of branch pipes are always kept in the closed state.
[0022]
In each of the above first to third inventions, the “fixed bathtub” is, for example, a general bathtub usually installed in a bathroom, and the “sub bathtub” is, in principle, any living room other than a bathroom or It is installed temporarily in the bedroom temporarily, or installed continuously, but always in a non-use state. Examples of such a sub-tub include an inflatable bathtub made of synthetic rubber, an assembled bathtub using a waterproof sheet, a bathtub provided stowably on a wall surface, or a bathtub formed of a synthetic resin. May be used as appropriate. In addition, in a bathroom having a large area in a hospital facility or the like, the present invention may be applied to a case where the above-described sub-tub is installed in another space as needed in addition to a general bathtub that is normally installed.
[0023]
The “bath pot” may be an ordinary bath pot having at least a hot water supply function and a reheating function. In the case of drainage, a part of the circulation circuit may be opened by, for example, manual operation by utilizing a drain plug provided in the circulation circuit of the bath kettle.

In the case of the above first invention, in order to take a bath for a care receiver or the like using the sub-tub, the sub-tub is installed in an arbitrary room in the building, and one end of the pair of extension connection pipes is connected to the sub-tub. Preparation is completed only by fitting the other end to the open end of the circulation pipe or the outlet of the branch pipe. At this time, the plug is connected to the outlet only by connecting and connecting the plug, and when the plug is separated after use, the plug is automatically returned to the closed state. Therefore, there is no concern that the room becomes wet with remaining hot water in the extension connection pipe or the branch pipe. Next, if the bath kettle is operated for hot water supply and the hot water is poured through the outgoing pipeline of the circulation pipe and one of the extension connection pipes connected thereto, bathing becomes possible. Then, by switching the bath kettle to the reheating operation and reheating the bath until the optimum temperature is reached, the temperature of the hot water can be easily adjusted and the drop of the temperature with time can be reliably prevented. When the bathing is completed, the water in the sub-tub is drained by the operation of the circulation pump provided on the bath pot side.
[0027]
In the first aspect of the present invention, the pair of branch pipes are disposed in the building in advance so that the extension connection pipe has a relatively short length up to the outlet. In addition to being easy to handle, it can be stored compactly. In addition, by arranging the branch pipes and the outlets in a plurality of rooms in advance, the degree of freedom in selecting a room in which the sub-tub is installed is increased, and depending on the situation where bathing in the sub-tub is required. It is possible to select the room to be installed.
[0028]
Further, in the case of the second invention, in order to take a bath for a cared person or the like using the sub-tub, the sub-tub is installed in a room provided with an outlet in the building or a room near the outlet, and a pair of baths is provided. The preparation is completed only by opening one end of the extension connection pipe into the sub bathtub, fitting the other end of the extension connection pipe into the outlet, and communicating with the circulation pipe. Next, as in the first invention, the bath can be supplied with hot water by supplying hot water through the outgoing pipe of the circulation pipe and one of the extension connection pipes connected to the same. Then, by switching the bath kettle to the reheating operation and reheating the bath until the optimum temperature is reached, the temperature of the hot water can be easily adjusted and the drop of the temperature with time can be reliably prevented. When the bathing is completed, the water in the sub-tub is drained by the operation of the circulation pump provided on the bath pot side.
[0029]
Furthermore, in the case of the third invention, in order to take a bath for the cared person or the like using the sub-tub, similarly to the case of the second invention, the room in the building where the outlet is provided or in the vicinity thereof. Preparation is completed only by installing a sub-tub in the room and opening one end of a pair of extension connection pipes into the sub-tub, and connecting the plug at the other end to the outlet to communicate with the circulation pipe. Next, if hot water for heating circulated from the hot water supply device to the heating device is poured through the outgoing pipeline of the circulation pipe and one of the extension connection pipes connected thereto, bathing becomes possible. Then, by using the temperature adjustment function of the hot water supply device to circulate hot water between the sub-tub and the hot water supply device to obtain the optimum hot water temperature, the hot water temperature adjustment can be easily performed and time elapses. The accompanying decrease in hot water temperature is also reliably prevented. When the bathing is completed, the hot water in the sub-tub is drained by the operation of the circulation pump provided on the hot water supply side.
[0030]
In each of the above second or third inventions, even if the plug is pulled out from the outlet for cleaning up after use, each of them automatically returns to the closed state, so that the remaining hot water in the extension connection pipe or the branch pipe is used. There is no worry about the room getting wet. In addition, since the pair of branch pipes are provided in the building in advance, the extension connection pipe may have a relatively short length up to the outlet, and the extension connection pipe can be easily handled at the time of arrangement. In addition, the storage can be made compact. Furthermore, by arranging the branch pipes and the outlets in a plurality of rooms in advance, the degree of freedom in selecting a room in which the sub-tub is to be installed is increased. It is possible to select the room to be installed.
[0031]
【The invention's effect】
As described above, according to the optional bath system of any one of the first to third inventions, pouring and reheating by omitting the work of loading and unloading hot water into and out of the sub tub installed as needed. Hot water temperature adjustment by circulation and drainage after use can be realized automatically and reliably. As a result, it is possible to omit heavy labor when bathing a protected person or a cared person in a bathtub other than a fixed bathtub, thereby reducing bathing and nursing care work and saving labor. It is possible to realize comfortable bathing even for a care recipient who takes a bath by appropriate and reliable hot water temperature adjustment by circulation or the like.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0033]
<First embodiment>
FIG. 1 shows an optional bath system according to a first embodiment of the present invention. In the figure, 1 is a fixed tub fixedly installed in a bathroom, 2 is a bath tub with a water heater for pouring and reheating the fixed tub 1, 3 is this bath tub 2 and the fixed tub 1 And 4, a sub-tub installed at any time in any room in the building, 5, 5 are circulation adapters attached to the fixed tub 1 and the sub-tub 4, 6 is a pair of extension connection pipes.
[0034]
The bath kettle 2 includes a hot water supply circuit 21, a reheating circuit 22, and a pouring circuit 23 for pouring hot water from the hot water supply circuit 21 into the reheating circuit 22.
[0035]
The hot water supply circuit 21 heats the water introduced into the hot water supply side heat exchanger 25 from the water supply line 24 connected to the general household water pipe by the combustion heat of the hot water supply side combustion burner 26, and discharges the heated water. Hot water is supplied to the hot water tap 28 at the downstream end through the conduit 27. A bypass pipe 29 for bypassing the hot water supply side heat exchanger 25 is connected to the water supply pipe 24 and the hot water supply pipe 27, respectively, and an unillustrated water amount adjusting valve provided in the bypass pipe 29 is opened. The temperature is controlled so that the water flows into the hot water from the heat exchanger 25 and the temperature of the hot water flowing out of the hot water tap 28 is adjusted. The combustion burner 26 receives a predetermined amount of fuel from a fuel supply pipe (not shown), and receives a supply of combustion air from a blower fan 30.
