If you try to use the shower while the bathroom has not been used for a long period of time, such as during the day or at night, the cold water that has accumulated in the water supply path between the water heater and the shower head will be discharged immediately after you start using it. . Therefore, even if the voice hot water temperature control means of Patent Document 1 is used, there is a risk that cold water will be poured immediately after starting to use the shower. Also, in winter, even if you do not bathe in cold water, you will feel cold in the bathroom for a while after taking a shower.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional circumstances, and aims to solve the problem of avoiding discomfort when starting to use a bathroom.

The water discharger of the present invention comprises a water discharger provided in a bathroom, a water supply channel for supplying hot water to the water discharger, a drain for discharging water in the water supply channel, and a bathroom. It has an instruction section that outputs an instruction signal for heating the interior, a receiving section that receives an instruction signal from the instruction section, and a control section. The control unit supplies hot water to the water supply passage based on the instruction signal input to the reception unit, and causes the water in the water supply passage to be discharged from the drain unit so that the temperature of the hot water in the water supply passage is heated. When a possible temperature is reached, water discharge from the water discharge part is stopped and discharge from the water discharge part is started.

If an instruction signal is output from the instruction unit before entering the bathroom, cold water in the water supply channel is discharged from the drain unit under the control of the control unit. Then, when the temperature of the hot water in the water supply channel reaches a temperature at which heating is possible, the drainage from the drain stops and the hot water is discharged from the water outlet into the bathroom, thereby warming the bathroom. Therefore, when starting to use the bathroom, the user does not feel uncomfortable due to cold water or cold air.

1 is a perspective view of a water discharger of Example 1. FIG. It is a block diagram showing the structure of a discharging apparatus. It is a front view showing the display form of a temperature setting operation part. It is a flowchart showing the control procedure of bathroom heating by a control part.

In the water discharger of the present invention, the control unit may output a notification signal for notifying completion of heating in the bathroom. According to this configuration, the completion of heating in the bathroom can be known outside the bathroom, so that the use of the bathroom can be started at the optimum timing.

In the water discharger of the present invention, the water discharger may include a mist water discharger and a large flow rate water discharger capable of discharging water at a larger flow rate than the mist water discharger. The large-flow water discharge section may serve as the drain section to discharge water in the water supply passage, and the mist discharge section may discharge hot water. Since the water in the water supply channel can be discharged from the high-flow water discharge part in a short time, the time required to complete heating can be shortened. Since the mist discharge part discharges hot water in the form of mist, it is possible to efficiently heat not only the floor of the bathroom but also the entire bathroom.

Therefore, only one of the four touch switches 25 is turned on to enable water discharge, and only one of the four water discharge units 11 to 14 is turned on. There are only one water discharger 11-14.

Each of the handles 21-24 can be rotated either clockwise or counterclockwise. The rotation angle of each handle 21-24 is individually detected by an angle sensor 28 (see FIG. 2). When the handles 21 to 24 corresponding to the water discharge units 11 to 14 in the ON state are rotated clockwise, the flow rate (supply amount) of hot water discharged from the water discharge units 11 to 14 changes according to the handle 21 to 24. It increases in proportion to the rotation angle. When the handles 21 to 24 are rotated counterclockwise while hot water is being discharged from the water discharging units 11 to 14, the flow rate (amount of hot water supplied) of the hot water discharged from the water discharging units 11 to 14 is increased by the handle 21 to . It decreases in proportion to the rotation angle of 24. When the handles 21-24 are rotated to a predetermined angle, the water discharge from the water discharge units 11-14 is stopped.

The water discharging device A has a waste water temperature sensor 47 . The drain temperature sensor 47 is provided only in the callan branch 44 (drainage channel) that is piped in the lowest area among the four branch channels 41 to 44 . A waste water temperature sensor 47 detects the temperature of hot water discharged from the tap water discharger 14 and outputs a waste water temperature detection signal 48 . The water discharger A has a bathroom temperature sensor 49 . The bathroom temperature sensor 49 is arranged in the bathroom B, detects the ambient temperature in the bathroom B, and outputs a detection signal.

The water discharger A has a controller 50 . The controller 50 is arranged inside the bathroom B (for example, inside the housing 10). The control unit 50 has a control function for discharging hot water at a set temperature from the selected water discharge units 11 to 14 at a set flow rate. In order to execute this control, as shown in FIG. A temperature setting signal 31 from a water supply temperature sensor 45 and a water supply temperature detection signal from a water supply temperature sensor 45 are inputted. Based on these signals, the control unit 50 electrically controls the opening/closing valve mechanism, the flow control mechanism, and the temperature adjustment mechanism of the mixing unit 38 and electrically controls the opening/closing operations of the four electromagnetic opening/closing valves 46 .

The control unit 50 avoids discomfort caused by exposing the body to the cold air in the bathroom B or bathing in the cold water discharged from the water discharging units 11 to 14 before starting to use the water discharging device A. It also has functions for Specifically, hot water is supplied from the mixing unit 38 into the water supply channel 36 while cold water in the water supply channel 36 is discharged, and hot water is sprayed in the bathroom B to heat the inside of the bathroom B. In order to control the heating, the control unit 50 receives a waste water temperature detection signal 48 from the waste water temperature sensor 47 and an instruction signal 53 output from the instruction unit 51 and passed through the reception unit 52. ing.

The instruction unit 51 is installed outside the bathroom B, or provided in a movable state outside the bathroom B. As shown in FIG. An example of the instruction unit 51 is a speech language recognition device having a microphone for detecting human voice, a language recognition unit for recognizing the meaning of the detected words, and a signal output unit for outputting the recognized words as the instruction signal 53. There is As an example of the instruction unit 51 by means other than voice, there is a method of operating a remote control device having a liquid crystal screen, or operating an application downloaded to a smart phone. A receiving unit 52 that receives an instruction signal 53 from the instruction unit 51 is arranged inside the bathroom B (for example, inside the housing 10). The instruction signal 53 input to the receiving section 52 is input to the control section 50 .

The control unit 50 has a function of notifying completion of heating when the heating in the bathroom B is completed. In order to execute this notification function, the control section 50 outputs a notification signal 55 toward the notification section 54 . Specific examples of the notification unit 54 include screen display on a speech language recognition device, remote control device, or smart phone, output of voice from the speech language recognition device, remote control device, or smart phone, or lighting or blinking of light. methods, etc.

Next, the mode of use of the water discharger A will be described. First, the temperature of hot water to be discharged from each of the water discharging units 11 to 14 is set. At the time of setting, by operating the temperature setting operation section 29, the water discharge section 11 to 14 desired to be used is selected, and the temperature of hot water desired to be discharged from the selected water discharge section 11 to 14 is set. The temperatures are sequentially set for each of the water discharging portions 11 to 14 . When the setting is completed, the character 35 of "End" is pressed. Information on the set temperature is stored in a storage unit (not shown) of the control unit 50 .

The control for pre-heating the bathroom B before use will be described with reference to the flowchart shown in FIG. When the instruction signal 53 from the instruction unit 51 is input to the control unit 50 (step S101), the branching for call run is performed while the electromagnetic on-off valves 46 of the branch paths 41 to 43 other than the call run branch line 44 are kept closed. The electromagnetic on-off valve 46 of the channel 44 (drainage channel) is opened (step S102), and hot water supply is started in the mixing section 38 (step S103). By this control, the cold water remaining in the water supply passage 36 is discharged from the water discharge portion 14 (drainage portion) from the downstream side of the water supply passage 36 through the branch passage 44 for water supply, and the water supply passage 36 Hot water is filled on the upstream side.

The water temperature sensor 47 detects the temperature of the water discharged from the faucet water discharger 14 . Based on the waste water temperature detection signal 48 from the waste water temperature sensor 47, the control unit 50 determines whether or not the discharge of residual water has been completed. When all the cold water in the water supply passage 36 is discharged, hot water is discharged from the water discharger 14 for the caller (step S104). It is detected by a waste water temperature detection signal 48 from a waste water temperature sensor 47 that hot water is being discharged from the water discharger 14 for callan.

When hot water is discharged from the water discharger 14 for quenching, the electromagnetic on-off valve 46 of the branch passage 43 for mist is opened (step S105), and hot water is discharged from the water discharger 13 for mist. At the beginning of the discharge, cold water remaining in the branch passage 43 for mist is discharged, but since the length of the branch passage 43 for mist is relatively short, the remaining cold water is discharged only for a short time. . Immediately after the discharge of the residual cold water is finished, high-temperature mist is sprayed in the bathroom B from the mist discharge part 13. - 特許庁

When the electromagnetic opening/closing valve 46 of the branch passage 43 for mist is opened, the electromagnetic opening/closing valve 46 of the branch passage 44 for rinsing is switched from the open state to the closed state (step S106), and the water discharge from the water discharge section 14 for rinsing is stopped. do. As mist continues to be discharged from the mist discharger 13, the ambient temperature in the bathroom B gradually rises. The temperature in bathroom B is detected by bathroom temperature sensor 49 . When the temperature in the bathroom B rises to the extent that the user does not feel uncomfortable (step S107), the heating control by the controller 50 ends.

When the heating control ends, the controller 50 outputs a notification signal 55 for notifying the completion of heating. The notification unit 54 to which the notification signal 55 is input notifies the user that the heating is completed by voice, text display, lighting of light, or the like. A user waiting outside the bathroom B can know the completion of heating in real time from the notification information from the notification part 54, so that the user can start using the bathroom B without wasting waiting time. . When the user enters the bathroom B, the inside of the bathroom B is already warmed to an appropriate temperature, so the user does not feel discomfort due to cold air.

Next, water discharge control from the water discharge units 11 to 14 by the control unit 50 will be described. When the touch switch 25 of the water discharge units 11 to 14 to be used is pressed, an ON/OFF signal is input from the touch switch 25 to the control unit 50 . The control unit 50 opens only the electromagnetic opening/closing valves 46 connected to the selected water discharge units 11 to 14 among the four electromagnetic opening/closing valves 46 provided in the branch passages 41 to 44, and opens the other three electromagnetic opening/closing valves 46. The on-off valve 46 is closed.

After that, when the handle 21-24 of the selected water discharger 11-14 is turned, the angle detection signal from the angle sensor 28 is input to the controller 50. FIG. When the angle detection signal is input, the control unit 50 calculates and sets the flow rate proportional to the rotation angle of the handles 21 to 24, and the detection signal from the water supply temperature sensor 45 and the selected water discharge unit 11 to 14. A control signal is sent to the on-off valve mechanism, the flow control mechanism, and the temperature control mechanism of the mixing unit 38 based on the stored information of the set temperature. As a result, the shared flow path 37 is opened, and hot water having the same temperature as the set temperature of the selected water discharger 11-14 is discharged from the water dischargers 11-14 at a flow rate corresponding to the rotation angle of the handles 21-24. .

Rotating the handles 21 to 24 clockwise during discharge increases the amount of hot water discharged, and rotating the handles 21 to 24 counterclockwise decreases the amount of hot water discharged. As for the rotation angles of the handles 21 to 24, when the touch switch 25 is turned on, the rotation positions of the handles 21 to 24 at that time are set as the origin (water stop position). When the handles 21 to 24 are rotated clockwise from this origin position, the amount of spouted water increases in proportion to the rotation angle from the origin. When the handles 21 to 24 are returned to their original positions, the water stops.

The water discharger A of the first embodiment has water dischargers 11 to 14 provided in a bathroom B. As shown in FIG. The water dischargers 11 to 14 include a mist water discharger 13 . The water discharger A has a water supply channel 36 for supplying hot water to the water discharge units 11 to 14, and a drainage unit (drain discharge unit 14) for discharging the water in the water supply channel 36. FIG. The water discharging device A has an instruction section 51 and a receiving section 52 . The instruction unit 51 is arranged outside the bathroom B and outputs an instruction signal 53 for heating the inside of the bathroom B. As shown in FIG. An instruction signal 53 from the instruction section 51 is input to the reception section 52 .

The water discharger A includes a controller 50 . Based on the instruction signal 53 input to the receiving unit 52 , the control unit 50 supplies hot water to the water supply passage 36 while discharging water remaining in the water supply passage 36 from the water discharge unit 14 for callan. When the temperature of the water in the water supply passage 36 reaches a temperature at which heating is possible, the control unit 50 stops the water discharge from the water discharge unit 14 for currants and starts discharge from the water discharge unit 13 for mist.

If the instruction signal 53 is output from the instruction unit 51 before entering the bathroom B, the control unit 50 controls the cold water in the water supply path 36 to be discharged from the water discharge unit 14 for callan. When the temperature of the water in the water supply passage 36 reaches a temperature at which heating is possible, the water discharge from the water discharge unit 14 for quenching stops, and hot water is discharged from the water discharge unit 13 for mist into the bathroom B. be warmed. Therefore, when starting to use the bathroom B, the user does not feel uncomfortable due to cold water or cold air.

Since the control unit 50 outputs a notification signal 55 for notifying the completion of heating in the bathroom B, the user waiting outside the bathroom B can remain outside the bathroom B. It can be known that the heating in the bathroom B has been completed. Therefore, the user does not need to go to the bathroom B to check whether the heating is completed, and can start using the bathroom B at the optimum timing.

The water discharger A has four water dischargers 11 to 14 including a mist water discharger 13 and a callan water discharger 14 capable of discharging water at a larger flow rate than the mist water discharger 13 . The callan water discharger 14 functions as a drainer and discharges water remaining in the water supply path 36 . The mist water discharge unit 13 discharges hot water for heating. Since the water in the water supply passage 36 can be discharged at a large flow rate in a short time from the faucet water discharger 14, the time required to complete heating can be shortened. Since the water discharge part 13 for mist discharges hot water in the form of mist, not only the floor of the bathroom B but also the entire inside of the bathroom B can be efficiently heated.
