Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water supply apparatus, and more particularly to a hot water supply apparatus in which a temperature is adjusted after selecting one of a plurality of water outlets in a bathroom washing place. The present invention relates to a hot water supply device configured to supply hot water. 2. Description of the Related Art Conventionally, a flush area such as a unit bath or the like is provided with a flush area such as a currant and a shower on a wall surface of a washing place, and these flush areas are shown in FIG. 8 and FIG. It is general that hot water adjusted to a required temperature is supplied from a hot water supply device configured as shown. That is, in this hot water supply device,
Hot water is supplied from only one of the shower 1 and the curran 2 selected by the valve operation.
Hot water and water introduced through the hot water introduction pipe 3 and the water introduction pipe 4 are mixed by the temperature control valve 5 to become hot water of a required temperature, and then connected to the outlet side of the temperature control valve 5. Then, the water is supplied from a water outlet portion of either the shower 1 or the cull 2 after passing through a water stop valve 6 having a flow path switching function. Therefore, when the bather uses the shower 1 or the curan 2, first, by operating the knob 5 a of the temperature adjustment valve 5, the temperature of which has been adjusted is obtained, and then the knob 6 a of the water stop valve 6 is turned. The switching operation to the shower 1 side or the curran 2 side is performed. [0004] In the hot water supply apparatus having the conventional configuration, the bather switches the knob 6a of the water stop valve 6 having a flow path switching function so that either the shower 1 or the callan 2 can be operated. Although the hot water is supplied from the water outlet, the operation of only the water stop valve 6 switches the water outlet to which the hot water is supplied, so that an erroneous operation is likely to occur and the inconvenience of poor usability occurs. . Therefore, in order to eliminate such inconvenience,
As shown in FIG. 10, it is conceivable to provide water stop valves 7 and 8 on each side of the water discharge site. That is, in this configuration, since each of the water discharge portions corresponds to each of the water stop valves 7 and 8, when the shower 1 is used, the water stop valve 7 on one side is operated, and When the callan 2 is used, it is only necessary to operate the water stop valve 8 on the other side. As a result, erroneous operation is less likely to occur and the usability is improved.
However, if such a configuration is adopted, it is necessary to supply hot water to each of the water discharge sites by connecting a branch T-shaped pipe 9 or the like to the outlet side of the temperature control valve 5. In addition, the piping connection structure becomes complicated, which not only increases the cost but also increases the occupied space. SUMMARY OF THE INVENTION The present invention has been made in view of these inconveniences, and it is possible to reliably prevent a bather from malfunctioning and to provide a hot water supply apparatus without complicating a piping connection structure. The purpose is to provide. A hot water supply device according to a first aspect of the present invention supplies hot water whose temperature has been adjusted from one selected water discharge site. A temperature control valve for mixing and supplying hot water at a required temperature; a first water stop valve interposed between the temperature control valve and one of the water discharge portions; A second water stop valve interposed between the water discharge portion and the first water stop valve, wherein the first water stop valve circulates in a state where the hot water supplied from the temperature control valve can stop water,
And, while having a main flow path connected to the water discharge site on one side, at least one bypass flow path through which the hot water supplied from the temperature control valve flows in a state where water cannot be stopped, The second water stop valve is characterized in that it is connected to the bypass flow path of the first water stop valve. An embodiment according to the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory view showing the overall configuration of a hot water supply apparatus according to a first embodiment, FIG. 2 is an explanatory view showing the external shape of the hot water supply apparatus, and FIG. 3 is a vertical sectional view of a first water stop valve. FIG. 4 is an explanatory view showing a cross-sectional configuration of the hot water supply apparatus. The hot water supply apparatus supplies hot water whose temperature has been adjusted from one selected water discharge site. In these figures, reference numeral 10 denotes a shower, 11 denotes a caran, 1
Reference numeral 2 denotes a hot water inlet pipe, 13 denotes a water inlet pipe, and 14 denotes a temperature control valve.
In addition, hot water at a required temperature is mixed with hot water and water introduced through the water introduction pipe 4. Reference numeral 14a in the figure denotes a knob provided on the temperature adjustment valve 14, and the temperature of hot water is adjusted by opening and closing the knob 14a. Further, between the temperature control valve 14 and the shower 10 which is a water discharge portion on one side is schematically shown in FIG. 1, and a first water stop valve 15 described later has a specific structure. While being interposed, a second water stop valve 16 having a normal configuration is interposed between the first water stop valve 15 and the water draining section 11 on the other side. The valves are arranged as shown in FIG.
Built in. In FIG. 2, the temperature control valve 14 and the first water stop valve 15 are arranged in parallel at the upper position of the device panel 17, and the second water stop valve 1 is positioned at the lower position.
Although 6 is arranged, it is a matter of course that the arrangement is not limited to such an arrangement state. However, in the present embodiment, the first water shutoff valve 15 is connected to the downstream side of the
Since the second water stop valve 16 is connected to the downstream side of the water stop valve 15,
It is desirable that the arrangement is as shown. Further, at this time, the first water shutoff valve 15
As shown in FIG. 3 and FIG. 4, the main body is provided with a main flow path through which the hot water supplied from the temperature control valve 14 flows and at least one bypass flow path. The hot water flowing in the main flow path from 15b through the valve port 20 to the outlet 15c is
As the valve body 19 incorporated in the device is operated with the knob 15a, the valve body 19 is circulated in a water-stoppable state. The shower 10 which is a water discharge site on one side is connected to the outlet 15c of the main flow path. Therefore, when the knob 15a is opened, warm water is supplied from the shower 10. The bypass flow path in the first water shutoff valve 15 is provided so as to extend from the inlet 15b of the housing 18 to the outlets 15d and 15e without passing through the valve port 20, and adjust the temperature. The hot water supplied from the valve 14 flows through the bypass flow path in a state where the water cannot be stopped. The second water stop valve 16 is connected to an outlet constituting one of these bypass flow paths, for example, the outlet 15d, and a knob 16 of the second water stop valve 16 is provided.
When a is opened, hot water is supplied from the curran 11. In other words, in the present embodiment, since the water outlets are the shower 10 and the caran 11, the first water shutoff valve 15 only needs to have at least one bypass flow path. The outlet 15e that constitutes the other side of the bypass flow path is closed using a plug or the like. Further, in the above description, the second
Although the water stop valve 16 is configured as usual, that is, has only the main flow path, the present invention is not limited thereto, and the main flow path and the bypass flow path similar to the first water stop valve 16 are provided. It is a matter of course that the outlet may be provided with a plug. In this case, all outlets constituting the bypass flow path are closed by plugs or the like. That is, in the present embodiment, hot water, which has been heated to a required temperature after mixing hot water and water, is supplied to the temperature control valve 14.
Is supplied to the first water stop valve 15, so that the hot water is supplied to the shower 10 through the main flow path of the first water stop valve 15, while the bypass of the first water stop valve 15 is performed. Hot water is supplied to the caran 11 through the flow path and the second water stop valve 16. Therefore, the first water stop valve 15 corresponds to the shower 10 at this time,
In addition, the curan 11 corresponds to the second water stop valve 16, and when each of the shower 10 and the callan 11 is used, only the corresponding first water stop valve 15 or the second water stop valve 16 is used. As a result of performing the opening operation, erroneous operation does not occur and usability is improved. By the way, in the first embodiment,
The shower 10 and the first water stop valve 15 correspond to each other,
And the normal second water stop valve 16 correspond to each other. However, as shown in FIG. 5 showing the entire configuration of the hot water supply device according to the modified example, the callan 11 is connected to the outlet 15c of the main flow passage capable of stopping water of the first water stop valve 15, and Outlet 1 of non-water-stoppable bypass flow path of water stop valve 15
5d through the second water shutoff valve 16 and the shower 1
0 may be connected, and in such a configuration, the shower 10 and the second water stop valve 16 correspond, and the
This means that the water stop valve 15 corresponds. In this case, the first water stop valve 15 is disposed at the center position of the device panel 17, the temperature control valve 14 is disposed on one side, and the second water stop valve is disposed on the other side. If a horizontal arrangement of the valves 16 is adopted, there is an advantage that the piping can be shortened and the entire space can be reduced. Next, an embodiment serving as a reference example of the present invention will be described. FIG. 6 is an explanatory view showing the overall configuration of a hot water supply apparatus according to an embodiment as a reference example , and FIG. 7 is an explanatory view showing a longitudinal configuration of a temperature control valve. Each of the regulating valves 22 and 23 is a water stop valve having a normal configuration. And these water stop valves 2
Each of 2 and 23 is interposed between the temperature control valve 21 and the shower 10 and the curran 11 which are the water discharge portions. That is, the temperature control valve 21 in this embodiment is for mixing hot water and water to supply hot water of a required temperature. Knob 21a for performing
A valve body 25 which is opened and closed by the operation is incorporated.
As shown in FIGS. 6 and 7, inlets 21 b and 21 c to which the hot water introduction pipe 12 and the water introduction pipe 13 are connected are connected to the temperature control valve 21, and at least two hot water supply ports are provided. Outlets 21d and 21e are provided, and a water stop valve 22 interposed between the hot water supply port 21d and the shower 10 is connected to the hot water supply port 21e. 11 is connected to a water stop valve 23 interposed therebetween. Reference numeral 28 in the figure denotes a mixing unit for hot water and water provided in the housing 24 that constitutes the temperature control valve 21.

[0020] Therefore, also in the hot water supply device according to the implementation in the form of this, each of the shower 10 and Curran 11 is a water outlet site will be Tomesuiben 22 and 23 correspond, shower 10 or When the callan 11 is used, one of the corresponding water stop valves 22 and 23 may be opened, and erroneous operation is unlikely to occur. In this embodiment, the outlets 21d and 21e, which are two hot water supply ports, are provided for the temperature control valve 21, but three or more hot water supply ports may be provided. At this time, the hot water supply port which is not required is closed using a plug or the like. As described above, according to the first aspect of the present invention,
In the hot water supply device according to the above, one of the water discharge portions is used because the water discharge portion on one side corresponds to the first water stop valve and the water discharge portion on the other side corresponds to the second water stop valve. In this case, only the water stop valve on the corresponding side needs to be opened, so that the malfunction of the bather can be reliably prevented. According to this hot water supply device, an effect is obtained that the cost and the occupied space can be prevented from increasing without complicating the piping connection structure. [0022]
