  The present invention was invented in view of the above-described conventional problems, and can selectively discharge water from any water outlet among the water outlets provided in a plurality of branch water channels by switching the switching means. When checking whether the hot water discharged from the water outlet is at an appropriate temperature, the remaining water in each branch waterway can be discharged from all the water outlets at the same time. Even if hot water is discharged from the water outlet, the cold residual water will not be discharged, and it can be used comfortably. In addition, the remaining water in each branch waterway is discharged from all the water outlets at the same time. It is possible to confirm whether the hot water is at the proper temperature with the amount of water used, and the remaining water and hot water discharged from the water outlet other than the hot water discharged from the water outlet for checking whether the temperature is appropriate are used by the user. It can be avoided, and With one switching valve, water discharge from multiple water outlets can be switched, the number of valves can be reduced and the cost can be reduced, and the switching operation with one switching valve makes it easy for the user to understand and erroneous operation It is an object of the present invention to provide a hot and cold water supply device without any problem.

In order to solve the above-described problem, the hot water supply apparatus according to the present invention connects a pipe 22 for supplying hot water to the switching means 1 on the upstream side of the switching means 1, and sets the water outlet 2 on the downstream side of the switching means 1. hot water supplying apparatus that selectively flow into any branch water passage 3 of the plurality of branch water passage 3 through the means switching the hot water supplied from the piping at the switching of the switching means 1 are connected a plurality of branch water passage 3 with 4, the switching means 1 switches the hot water supplied from the pipe 22 to the optional branch water channel 3 through the switching means 1 and the hot water supplied from the pipe 22 to the switching means 1. It is characterized by having the switching which flows simultaneously to all the branch water channels 3 via .

With such a configuration, hot water supplied from the pipe 22 can be selectively discharged from any of the plurality of water outlets 2 by switching of one switching means 1, and the switching operation can be performed. It is simple and there is no risk of misoperation, there is no risk of hot water or cold water being discharged from an unexpected direction and it will be applied to the user, and since only one switching means 1 is required, the number of valves to be used is The switching means 1 is supplied from the piping 22 to confirm whether or not the hot water discharged from the water outlet 2 is at an appropriate temperature in use. that hot water of a switched it to flow hot water to all branches waterways 3 simultaneously, which all residual water in each branch water passage 3 from the water discharge port 2 can be discharged at the same time, this result, then, double Even when spouting the hot water from any of the spout 2 of the spout 2, cold residual water without be spouted, so that it is comfortable use.

  Further, in a switching state in which hot water flows through all the branch water channels 3, a larger flow rate is supplied to one specific branch water channel 3 among the plurality of branch water channels 3, and a flow rate to be supplied to the remaining branch water channels 3 is set to the specific one branch. It is preferable that the flow rate is set to be smaller than the flow rate flowing through the water channel 3.

  With such a configuration, when discharging the remaining water in each branch water channel 3 from all the water outlets 2 at the same time as described above, a large amount of hot water is discharged only from the specific water outlets 2 and the specific water outlets are discharged. The hot water temperature can be checked by touching only the hot water coming out of the water outlet 2, and at the same time, only a small amount of hot water required to discharge only the remaining water in the branch water channel 3 is allowed to flow from the other water outlets 2. As a result, when checking the hot water temperature and draining the remaining water, the hot water does not come out from the water outlet 2 other than the specific water outlet 2, and the residual water and hot water are not applied to the user. In addition, the amount of hot water used can be reduced.

  The plurality of water outlets 2 provided in the plurality of branch water channels 3 include at least a spray water outlet 2 a for spraying hot water, a water outlet 2 b for a washing place, and a hand shower water outlet 2 c provided in the hand shower 5. Three or more types are preferable.

  Further, it is preferable that the switching means 1 is set so that the flow rate to flow to the hand shower spout 2c is large and the flow rate to flow to the remaining spouts 2 is small while hot water is simultaneously flowing to the plurality of spouts 2. .

  Thus, since the specific water outlet 2 for confirming the said hot water temperature is the hand shower water outlet 2c provided in the hand shower 5, the user can carry out the said hot water temperature confirmation work with the hand shower 5. The hot water temperature can be easily checked, and the hot water temperature can be checked while the hand shower 5 is moved as far as possible from the other water outlets 2. Residual water discharged from the spout 2 can be prevented from being discharged to the user, and when the temperature of the hot water is checked with the hand shower 5, the hand shower 5 is held and the hot water is sprayed on the bathroom floor. Use such as warming the floor is also possible.

  Moreover, it is preferable that some of the plurality of water outlets 2 to which hot water is supplied have means for distinguishing between the use state and the non-use state, and the water discharge range is limited in the non-use state.

  By setting it as such a structure, when draining the residual water in each branch water channel 3 from all the spouts 2 simultaneously, it can be made into a non-use state, and it can prevent that a residual water and hot water apply to a user.

As described above, the present invention can provide a compact and inexpensive apparatus that can change the water discharge port by operating one switching means, improves operability, improves safety, and supplies hot water supplied from piping. Since there is a switching to flow through all the branch water channels simultaneously through the switching means, when checking whether the hot water discharged from the water outlet is at an appropriate temperature, the switching means is a hot water supplied from the pipe. By switching so that hot water flows into all branch waterways at the same time , the remaining water in each branch waterway can be discharged simultaneously from all water outlets, and hot water can be discharged from any of the water outlets. The cold residual water does not discharge and can be used comfortably.

Therefore, the head of the hand shower 5 can be removed from the wall 7 and used for washing or washing the face.

  In addition, as shown in FIG. 2, the seating means 14 can be used as a counter for installing a wash basin 15 and bathing articles in a state where the nozzle arm 9 is housed and the back cover 10 is opened. In this state, the hand shower 5 can be used as described above by switching the switching means 1 to the “hand shower” position. In addition, by switching the switching means 1 to the “washing area spout” position, normal bathing operations such as washing the face and towels by washing out hot water from the washing area spout 2b and storing the hot water in the basin 15 are performed efficiently. Can be done automatically.

  As described above, in the present embodiment, the nozzle arm 9 is rotated upward to be held at a predetermined position, and is seated on the seating means 14 and the switching means 1 is switched, whereby the spray outlet 2a and the mist By selectively switching the hot water from the four different water outlets 2, the water outlet 2 e, the massage outlet 2 d, and the hand shower outlet 2 c, the four types of shower baths, massages and washing operations as described above can be performed. Moreover, in the state which accommodated the nozzle arm 9, the washing | cleaning operation | work using the hand shower 5 and the normal bathing operation | work which discharges hot water from the spout 2b for washing places can be performed.

In the present invention, the switching means 1 has switching for flowing hot water in all branch water channels 3 in addition to switching for selectively flowing hot water in any branch water channel 3, that is, switching Since there is an “appropriate temperature confirmation position” that allows hot water to flow through all the branch water channels 3 simultaneously as a switching setting position of the means 1, the switching means 1 is rotated to set the “appropriate temperature confirmation” position before use. As shown in Fig. 5, the proper temperature of the hot water coming out from the water outlet 2 can be confirmed, and all the cold residual water staying in all the branch water channels 3 can be drained at the same time. After that, even if the switching means 1 is switched and water is discharged from any remaining spout 2, hot water at the set temperature is spouted, and the switching means 1 is switched and the remaining cold from another spout 2 is left. water No fear that that water discharge to take the user, so that it is comfortable use.

Here, when all the cold residual water staying in all the branch water channels 3 is drained at the same time by checking the appropriate temperature, the back cover 10 is opened as shown in FIG. 2, and the left and right nozzle units 8 and the left and right nozzles are opened. The arm 9 is covered with the backrest cover 10, and the switching means 1 is used in a non-use state of the left and right nozzle units 8, the spray water outlet 2a, the massage water outlet 2d, and the mist water outlet 2e provided in the left and right nozzle arms 9. Is set to the “appropriate temperature confirmation position” and hot water is allowed to flow through all the branch water channels 3, the spray nozzle 2a, the massage nozzle 2d provided in the left and right nozzle units 8, the left and right nozzle arms 9, The water discharge range from the water outlet 2e for mist is restricted by the backrest cover 10 so that it is not applied to the user.

  Further, when the switching means 1 is set to the “appropriate temperature confirmation position” and hot water is allowed to flow through all the branch water channels 3 as described above, the flow rate to flow through one specific branch water channel 3 among the plurality of branch water channels 3. It is preferable that the flow rate of flowing in the remaining branch channel 3 is set smaller than the flow rate of flowing in the one specific branch channel 3.

  For example, one of a plurality of water outlets 27 ′ arranged in a line in the axial direction has a larger water flow rate than the other water outlets 27 ′. As a result, when discharging the residual water in each branch water channel 3 from all the water outlets 2 at the same time, a large amount of hot water is discharged only from the specific water outlet 2 and only the hot water discharged from the specific water outlet 2 is applied to the hand. The hot water temperature can be checked at the same time, and at the same time, only a small amount of hot water required to discharge only the remaining water in the branch water channel 3 is allowed to flow from the other outlets 2. When draining water, hot water does not come out vigorously from the water outlets 2 other than the specific water outlet 2, and no residual water or hot water is applied to the user (in this case, the back cover 10 is closed). The remaining water and hot water are not applied to the user), and the amount of hot water used can be reduced.

  In the embodiment shown in FIG. 5, the water flow rate of the hand shower water flow port 27 c ′ is the same as the water flow rate of the wash water flow port 27 b ′, the massage water flow port 27 d ′, the spray water flow port 27 a ′, and the mist water flow port 27 e ′. More than that. In other words, the amount of water flowing through the wash water outlet 27b ', the massage water outlet 27d', the spray water outlet 27a ', and the mist water outlet 27e' is the wash water branch water channel 3b, the massage water branch 3d, and the spray water branch. It is sufficient that there is an amount of water necessary for draining the cold remaining water remaining in the water channel 3a and the mist branch water channel 3e, which is a wash water branch water channel 3b, a massage water channel 3d, a spray water channel 3a, The amount of water may be determined by the length of the branch water channel 3e for mist or the like. On the other hand, the amount of water flowing through the hand shower water outlet 27c ′ is not only draining the cold residual water in the hand shower branch water channel 3c, but also checking whether the hot water coming out after the residual water is at an appropriate temperature. Since it is necessary to touch and confirm, the water flow is increased.

  As described above, since the amount of water flow through the hand shower water outlet 27c ′ can be increased and the confirmation work can be performed with the hot water discharged from the hand shower water outlet 2c of the hand shower 5, the user can hold the hand shower 5 with the above hot water temperature. The hot water temperature can be easily checked, and the hot water temperature can be checked while the hand shower 5 is moved as far as possible from the other outlets 2. It is possible to prevent the user from draining the residual water discharged from the water outlet 2 of the water. In addition, after checking the hot water temperature with the hand shower 5, the hand shower 5 can be held as it is to spray the hot water on the bathroom floor to warm the bathroom floor or the seating means 14. It becomes.

  The reason for increasing the amount of water flow through the hand shower water outlet 27c ′ when the “appropriate temperature confirmation position” is set as described above is that there are many possible ways to use the water discharged from the hand shower 5, so that the cold water is removed. This is because it is the best water discharge means that can leave the user the method of using water without waste.

  As a method of use of the present invention, the switching means 1 is rotated and set to the “hand shower” position to check the hot water temperature, and when warmed, the switching means 1 is rotated and moved to the “appropriate temperature confirmation position” after a few seconds. There is also a method of heating even if the remaining water in each branch water channel 3 is discharged simultaneously from a plurality of water discharge ports 2 by switching. In this case, it is not necessary to increase the water flow rate only at the hand shower water flow port 27c 'at the "appropriate temperature confirmation position".

  Further, the apparatus of the present invention can perform a shower bath and a normal bathing operation at the same place as described above, and the switching means 1 can also be performed by operating only one handle 1a. It is not necessary to secure an extra space, the switching means 1 is not complicated, the concealed space can be reduced, and the space saving and usability of the bathroom can be improved.

In the present embodiment, the auxiliary stopper 30 provided in the switching means 1 is installed at one place. However, it may be installed at a plurality of places when it is considered necessary depending on the state of water discharge, thereby improving safety and operability. Can be improved. Further, although the sub stopper 30 has a structure that stops in one direction, depending on the state of water discharge, it may be possible to improve safety and operability as a structure that stops from both sides.

  In addition, since the thing of the said embodiment can perform the washing | cleaning operation | work of a shower bath and a general bath in the same place as mentioned above, various shower baths can be switched by the switching operation by one switching means 1. Since it is not necessary to secure an extra space in the bathroom and it is possible to improve the space-saving and usability of the bathroom, it can be applied to uses such as a care apparatus.

  Moreover, although the above-mentioned embodiment demonstrated the example of the shower apparatus installed in a bathroom as the hot-water supply apparatus 4 of this invention, the some branched water channel which has the spout 2 in the downstream of the switching means 1 to which hot-water is supplied, respectively. 3 and the hot water supply device 4 in which hot water is selectively allowed to flow into an arbitrary branch water channel 3 among the plurality of branch water channels 3 by switching of the switching means 1, is not necessarily limited to a shower device installed in a bathroom. Of course, it is not limited.
