As shown in the figure, in the bath water heater of the present invention, a return pipe 3 to the body of the water heater (in this case, the hot water bath kettle 1) is connected to the opening 2a formed on the side surface of the bathtub 2 so as to communicate with the inside of the bathtub 2. The discharge port body 7 to which the hot water supply pipe 4 from the hot water supply bath pot 1 is connected is attached to the counter 33 adjacent to the bathtub 2. This hot-water supply bath pot 1 is equipped with a heat exchanger, a circulation pump, a solenoid valve, various sensors and a microcomputer for controlling these, which are not shown, as in the conventional one, and is supplied with water from a water supply pipe 5 or a return pipe. The hot water in the bathtub 2 sucked from 3 is heated when passing through the internal heat exchanger, and the hot water supply pipe 4
It is sent from. Here, in the present invention, the hot water supply pipe 4 communicates with the pipe that passes through the heat exchanger of the hot water supply bath kettle 1 and communicates with the water supply pipe 5 side, and also through the heat exchanger that communicates with the return pipe 3 side. The pipe is connected via a three-way valve (not shown).

Further, a hot water tap 8 for shower provided in the washing room 13 is connected to a hot water supply pipe 6 of another system drawn out from the hot water bath kettle 1.

As shown in FIG. 3, the discharge port body 7 is provided in the mixed faucet mounting ports 33a, 33a provided in advance in the counter 33 adjacent to the bathtub 2, and the mixed faucet mounting ports 33a, 3a.
It is formed wide so that it can be attached by closing 3a, and a sprue 7a is formed on the inner side surface (tub side) of the opening. Further, a remote controller 9 for controlling the bath function of the hot water supply bath pot 1 is attached to the upper surface thereof. Code 11
Indicates the code of the remote controller 9. FIG. 4 is a plan view of the remote controller 9.

In addition, the tap 8 of the washing room 13 is shown in FIG.
As shown in, a remote controller 10 for controlling the hot water supply function of the hot water supply bath pot 1 is attached. In FIG. 1, reference numeral 12
Indicates the code of the remote controller 10.

As described above, in the bath water heater of the present invention, the water supply pipe 5 is only connected to the hot water bath kettle 1 and is not connected to the bathtub 2 or the washing room 13 side at all.

Next, various operations of the bath water heater of the present invention having the above-mentioned structure will be described. First, in order to boil the bath water 2, the desired temperature is controlled by the remote controller 9 on the upper surface of the discharge port body 7 attached to the counter 33. It is only necessary to set the water level and press the fully automatic switch, whereby a microcomputer (not shown) installed on the basis of the input value controls the hot water supply bath pot 1 to start the hot water burr. At this time, in the bath hot water supply apparatus of the present invention, the microcomputer controls the normal hot water bath, and at the same time, the water supply pipe 5 is connected to the hot water supply pipe 4 connected to the discharge port body 7 in the hot water supply bath pot 1. It drives an internal three-way valve (not shown). Therefore, the water supplied from the water supply pipe 5 passes through a heat exchanger (not shown) in the hot water supply bath kettle 1, is heated, and is sent from the hot water supply pipe 4 to the discharge port body 7 to one side thereof.

In addition, in order to remove the hot water in the bath tub 2, it is sufficient to press the re-push switch of the remote controller 9 on the upper surface of the discharge port body 7, whereby the circulation pump (not shown) installed in the hot-water bath tub 1 is pushed. At the same time as the operation, the three-way valve switches to the direction in which the return pipe 3 and the hot water supply pipe 4 communicate with each other, the hot water in the bathtub 2 is sucked from the opening 2a, heated in the hot water supply bath kettle 1, and then dropped from the discharge port body 7. Then, it is returned to the bathtub 2. In this way, the hot water in the bathtub 2 is circulated to drive it away. At this time, in the bath water heater according to the present invention, the opening 2a serving as the hot water suction port and the sprue 7a of the discharge port body 7 serving as the hot water discharge port.
Since it is distant from the above, the short circuit in which the heated hot water is immediately sucked is unlikely to occur, and the hot water circulating in the bathtub 2 is reliably heated. Although FIG. 2 shows an example in which the opening 2a and the discharge port body 7 are provided on the same side of the bathtub 2, the opening 2a and the discharge port body 7 may be provided on different sides of the bathtub 2, in which case Therefore, the circulation heating of the hot water described above can be performed more reliably.

The circulation of the hot water in the bathtub 2 is not necessarily limited to the repulsion, but the circulation may be performed without operating the heat exchanger.

In order to use the tap 8 provided in the washing room 13, it is sufficient to operate the remote control 10 attached to the tap 8, whereby the water supplied from the water supply pipe 5 is supplied to the bathtub 1 of the hot water supply bath. It is heated by the heat exchanger and sent to the hot water tap 8 through the hot water supply pipe 6. Since the hot water tap 8 is not connected to a water supply pipe, temperature control is entirely performed by the control of the hot water bath kettle 1.

In this embodiment, the example in which the remote controllers 9 and 10 are attached to both the discharge port body 7 and the hot water tap 8 is shown, but it is also possible to attach a remote controller for operating both to either one. good. Also, this remote control 9, 10
Shows an example in which they are electrically connected to the hot-water bath pot 1 via cords 11 and 12, respectively.
May be electrically connected to the hot-water / bath pot 1 wirelessly.

Further, the hot-water supply bath pot 1 which can be repelled as the main body of the external hot-water supply device has been illustrated, but the main body of the hot-water supply device connected to the bathroom side such as the bathroom unit is a hot-water supply device capable of supplying only hot water. Yes, in this case, return pipe 3
The opening 2a of the bathtub 2 to which the return pipe 3 is connected is unnecessary.

Furthermore, in the above example, the discharge port body 7 is provided in the counter 33 adjacent to the bathtub 2, but this discharge port body 7 only needs to supply hot water to the bathtub 2 and the vicinity of the bathtub 2. It may be attached to the wall surface of.

[0027]

As described above, according to the first aspect of the present invention, since the remote controller is attached to the discharge port body for supplying hot water to the bathtub, the remote controller can be installed in the bathroom in a good appearance. Further, since the temperature control is performed by the function of the water heater main body side, there is also an effect that the connection of the water supply pipe is unnecessary and the member cost and the construction cost are reduced.

In addition to the effect of the invention described in claim 1, the invention described in claim 2 has an effect of eliminating the defective circulation at the time of re-pushing.
