[Industrial applications]

 This invention relates to a bath system.

[0002]

[Prior Art]

 A conventional bath system using a heat pump system (for example, see Japanese Patent Laid-Open No. 3-230049) will be described with reference to FIG. In the figure, 50 is a bathtub, 60 is a reheating unit, and 80 is a hot water tank unit. The reheating unit 60 has a pair of communication ports 61 and 62, a hot water inlet port 63, and a water inlet port 64. The communication ports 61 and 62 are connected to the bathtub 50 by a pair of communication pipes 51 and 52. A hot and cold water circulation passage 65 is connected to both the communication ports 61 and 62, and a water level sensor 66, a three-way valve 67, a circulation pump 68, and a bath heat exchanger 69 are connected to the hot and cold water circulation passage 65 in that order from the upstream side thereof. Each is installed. The hot water inlet port 63 and the water inlet port 64 are connected to a mixing valve 72 via check valves 70 and 71, respectively, and the mixing valve 72 is connected to a vacuum breaker 73. Further, the vacuum breaker 73 is connected to the three-way valve 67 through a pipe 75 provided with a check valve 74. The hot water tank unit 80 is provided with a hot water outlet 82 from the hot water tank 81 and a tap water outlet 83, and the outlets 82 and 83 are connected to the hot water inlet port 63 by a pair of communication pipes 84 and 85. It is adapted to be connected to the water inlet port 64.

In the above bath system, at the neutral position of the three-way valve 67, the bath water is circulated in the hot and cold water circulation path 65 and heated by the bath heat exchanger 69 while the three-way valve 67 is switched, Hot water supplied from the hot water storage tank unit 80 side is supplied to the bathtub 50 through the hot water circulation passage 65.

[0004]

However, the conventional bath system described above has the following drawbacks. When installing the vacuum breaker 73, it is necessary to install the vacuum breaker 73 at a position higher than the bathtub dull surface H by a certain distance L (for example, 30 cm). Therefore, the entire reheating unit 60 must be installed. Since it needs to be installed in a relatively high place, it requires a lot of labor for the installation work, and in some cases, the installation becomes impossible.

If the connection destinations of the hot water outlet 82 and the tap water outlet 83 of the hot water storage unit 80, that is, the hot water inlet port 63 and the water inlet port 64 are reversed, hot water cannot be discharged due to the structure of the mixing valve 72. Therefore, there is also a drawback that this connection work requires considerable caution.

The present invention has been made in order to solve the above-mentioned conventional drawbacks, and an object thereof is to provide a bath system capable of greatly relaxing restrictions on installation and thus facilitating installation work. To provide.

[0007]

[Means for Solving the Problems]

 Therefore, the bath system according to claim 1 comprises a reheating unit 20 connected to the bathtub 10 and a hot water tank unit 40 for supplying hot water to the reheating unit 20, and the reheating unit 20 is connected to the bathtub 10. Having a pair of communication ports 21 and 22 and a hot water inlet port 23 connected to the hot water storage tank unit 40, and a circulation pump 28 and a heat exchange for bath in a hot and cold water circulation passage 25 connected to the communication ports 21 and 22. The hot water inlet port 23 is connected via the switching valve 27 to the hot water circulating passage 25 so as to be switchably communicable therewith. The hot water storage tank unit 40 is provided with hot water from the hot water storage tank 41. A mixing valve 46 for mixing water and tap water, and a vacuum breaker 47 connected to the mixing valve 46 are provided, and the vacuum breaker 47 is provided. Of become placed on top, is characterized in that this vacuum breaker 47 has at contact piping 48 and configured to connect to the hot water inlet port 23 of the add-fired unit 20.

[0008]

[Action]

 In the above bath system, the vacuum breaker 47 is arranged at the top of the tall hot water tank unit 40, so that the vacuum breaker 47 is arranged at a position sufficiently higher than the bath deflation surface. In the reheating unit 20, the restrictions on the installation due to the presence of the vacuum breaker 47 will be greatly eased.

Further, since there is only one connecting pipe 48 between the hot water storage tank unit 40 and the reheating unit 20, piping mistakes do not occur.

[0010]

【Example】

 Next, a specific embodiment of the bath system of the present invention will be described in detail with reference to the drawings.

In FIG. 1, 10 is a bathtub, 20 is a reheating unit, and 40 is a hot water tank unit. The reheating unit 20 includes a pair of communication port ports 21 and 22 and a hot water inlet port 23. The communication ports 21 and 22 are connected to the bathtub 10 by a pair of communication pipes 11 and 12. A hot and cold water circulation passage 25 is connected to both the communication ports 21 and 22, and a water level sensor 26, a three-way valve 27 as a switching valve, a circulation pump 28, and a heat exchange for bath are sequentially connected to the hot and cold water circulation passage 25 from the upstream side thereof. The containers 29 are respectively provided. The hot water inlet port 23 and the three-way valve 27 are connected by a pipe 31 provided with a check valve 30.

On the other hand, the hot water tank unit 40 is provided with a hot water passage 42 through which hot water discharged from the hot water tank 41 passes and a tap water passage 43 through which tap water passes. Check valves 44 and 45 are provided in the passages 43 and 43, respectively, and their rear portions are joined to the mixing valve 46. A mixing valve 46 is connected to the vacuum breaker 47, and a vacuum breaker 47 is further connected to the hot and cold water inlet port 23 of the reheating unit 20 by a connecting pipe 48.

In the above-mentioned bath system, the bath water is circulated in the hot water circulation circuit 25 at the neutral position of the three-way valve 27, and the reheating operation is performed in which the bath heat exchanger 29 heats the three-way valve 27. When the switching is performed, the mixed hot water supplied from the hot water storage tank unit 40 through the communication pipe 48 is supplied to the bathtub 10 through the hot water circulation passage 25, so-called hot water welding can be performed.

A point to be noted here is that the vacuum breaker 47 is arranged at the highest portion of the hot water tank unit 40. Since the hot water storage tank unit 40 is originally tall, if the vacuum breaker 47 is arranged in this way, the vacuum breaker 47 is installed at a position sufficiently higher than the duff surface H of the bathtub 10. And can satisfy the installation obligations. As a result, the reheating unit 20 does not have the conventional restrictions on installation, and as a result, the situation that installation is not possible can be resolved and the installation work can be facilitated.

Further, since the connection pipe 48 between the hot water tank unit 40 and the reheating unit 20 is made into one, the pipe connection mistake can be eliminated, and the installation work can be facilitated also in this respect. Moreover, since the reheating unit 20 whose installation position is limited can be made more compact than the conventional one, the installation work can be further facilitated in this respect as well. Further, the electric system does not need to be changed from the conventional example shown in FIG. 2, so that there is an advantage that the implementation is easy.

[0016]

[Effect of the device]

 As described above, in the bath system according to claim 1, since the vacuum breaker is arranged at the top of the tall hot water tank unit, the vacuum breaker is arranged at a position sufficiently higher than the bath deflation surface. Therefore, in the reheating unit, the restrictions on the installation due to the presence of the vacuum breaker will be greatly relaxed, and therefore the installation work can be facilitated.

Further, since only one connecting pipe is required between the hot water storage tank unit and the reheating unit, piping mistakes do not occur, and also in this respect, the installation work can be facilitated.
