Abstract

PURPOSE:To prevent cooling water from being discharged by setting a water temperature detector near a washing nozzle, to permit residual water to overflow and to permit a water temperature in a piping to stand by with a set value, and by contriving a washing switch not to be worked before the standby state. CONSTITUTION:Near the washing nozzle 1 of a device main-body A, a water temperature detector is set, and on a functional section B, a valve device C for controlling discharged water (d) from the nozzle, and an elctronic valve unit D are arranged. After that, a user sits down on a closet seat, and after that, by prewashing and residual water dispasal operation, cool water stored in a water discharging piping is discharged (c) or overflow (e), and the washing water of a set temperature is permitted to stand by. Besides, before the standby state, water is contrived not to be discharged even if a washing switch is operated. As a result, washing can be always performed at a comfortable temperature.

[Prior Art] In sanitary cleaning equipment for hotel facilities and the like that has hot water cleaning functions such as anal cleaning and bidet cleaning, water and hot water are supplied to the equipment through piping from other equipment. In order to perform the function of comfortable private washing with hot water, the water supply and hot water supply equipment must be operated normally so that the temperature of the hot water that is mixed and discharged is stably maintained within a predetermined range. is necessary. It is also necessary to control the operation so that the hot water for washing private parts is stably maintained within a comfortable temperature range. Therefore, in this type of sanitary washing device, in order to keep the hot water supply temperature above 42°C, after the user is seated, the supplied hot water is discharged from the piping until the hot water temperature reaches 42°C. After the water temperature has been mixed and controlled, the cooled water is discharged from the pipe, and the "residual water treatment operation" is continued until the discharged water temperature reaches a predetermined temperature, and the system is on standby in preparation for discharging water during cleaning. It has become.

0003

[Problems to be Solved by the Invention] However, even if the structure is such that preparations for discharging water at a predetermined temperature are completed and the cleaning water is on standby, in the configuration of the conventional device, the cleaning switch is operated before the standby state. However, there was a problem in that cold water was discharged from the water discharge piping.

The present invention was devised in view of the above-mentioned problem, and is a switch reception method in a sanitary washing device that allows washing at a comfortable water temperature whenever the washing switch is operated and water is spouted. The purpose is to provide a mechanism.

[0005]

[Means for Solving the Problems] The reception mechanism of the switch in the sanitary cleaning device according to the present invention mixes and adjusts the water and hot water supplied to the device and discharges the mixture, and performs hot water cleaning functions such as anal cleaning and bidet cleaning. In order to stably maintain the temperature of the discharged wash water within a predetermined range, the hot water supplied in the discharge pipe is discharged through the nozzle pre-cleaning pipe until the mixed hot water reaches a constant temperature. In a sanitary washing device configured to perform "cleaning and residual water treatment operations," a water temperature detection means is provided in the vicinity of the nozzle in the water discharging pipe in which the pre-cleaning and residual water treatment means are installed, and the pre-cleaning and residual water treatment A cleaning signal detecting means is provided which waits for cleaning water by overflowing residual water in the pipe until the temperature in the water discharge pipe reaches a preset temperature, and prevents reception of a cleaning switch before the standby state, The purpose is to maintain the temperature of the hot water for cleaning within a set range.

[0006]

[Operation] Therefore, after the user sits on the toilet seat, when hot water at a preset temperature is obtained, the pre-cleaning/residual water treatment means transfers the cooled water accumulated in the water spouting pipe to the nozzle cleaning water. The water overflow operation is performed as shown in FIG. The cleaning signal detection means detects the pre-cleaning signal in the previous stage.
In order to prevent input from the cleaning switch operation means until the pre-treatment completion signal from the residual water treatment means is input, the water temperature in the piping is set to a preset value (for example, 41°C). Only the washing water can be spouted, ensuring that washing is always carried out at a comfortable water temperature.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a switch receiving mechanism in a sanitary cleaning device according to the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 shows the configuration of a piping system of a sanitary cleaning device equipped with a functional device implementing the present invention.
Reference numeral 1 denotes a private part cleaning nozzle constructed on the main body part A. This nozzle 1 is moved to a predetermined use position (
The rear end of the nozzle 1, which communicates with the discharge hole for discharging warm water for washing, has a check valve 3 that branches off the overflow pipe. Solenoid valve 4 of valve unit C configured in functional part B via
A thermistor sensor 5 for a temperature limiter is connected to the downstream stage and outputs the pipe internal temperature T3 to a pipe line communicating with the nozzle 1, and monitors the temperature of the discharged water d. This solenoid valve 4 for discharging water has a structure in which it is driven to open and close by control signals from the pre-cleaning/residual water treatment means 25 and the cleaning signal detection means 29 of the central control device 18.

The thermovalve 6 of the temperature control system constituting the electronic valve unit D of the functional section B is controlled by changing the mixing ratio by a mixing motor 7 driven by a control signal from a thermovalve control means 19, which will be described later. It is configured to control the temperature of the secondary side water supply communicating with the solenoid valve 4 of C to a preset temperature (42°C), and the thermistor sensor 8 for temperature control is installed in the water discharge pipe 17 on the secondary side. It is provided. The thermovalve 6 of the electronic valve unit D is for supplying water and hot water from the external equipment of this device to the primary side, and the water supply pipe a is connected via a check valve 9 with a strainer and a pressure reducing valve 10. On the other hand, the hot water supply pipe b is connected via a strainer-equipped check valve 11 and a pressure reducing valve 12, and also communicates with a waste water solenoid valve 13 provided in the valve unit C. A thermistor sensor 14 for controlling the waste hot water is provided in the branch pipe. The secondary side of the waste water solenoid valve 13 communicates with a waste water pipe c that communicates with the secondary side pipe line of the throttle valve 15 configured in the valve unit C, and the throttle valve 15 is connected to the solenoid valve 15. A structure in which the flow rate adjustment motor 16 controls the amount of water flowing to the waste water pipe c side and adjusts the flow rate of the hot cleaning water flowing to the nozzle 1. It has become.

FIG. 2 is a block diagram showing an embodiment of the central control unit 18 of this apparatus which controls and drives the piping system. The waste hot water ON/OFF control means 21 that controls opening and closing of the waste water electromagnetic valve 13 is a thermovalve control means 1.
The opening degree is controlled by 9, and the control operation is started by the "seating" signal from the seating detection means 20 configured at the toilet seat position of the main body part A, and the waste water temperature detection device consisting of the thermistor sensor 14 for waste water control. The temperature information T1 of the means 22 (
(below 42°C). This waste bath ON/
The OFF control means 21 counts the time t1 from the ON drive using the waste hot water time control means 23, and the hot water temperature failure determination means 24 connected at the subsequent stage determines that the time t1 exceeds a preset time (for example, 2 minutes). If this happens, it is judged as an "abnormality" and a pulse signal is issued, and this signal turns on/off the drain water.
The FF control means 21 operates to turn the waste hot water electromagnetic valve 13 OFF. If the time t1 does not exceed 2 minutes, it is determined to be "normal" and the subsequent pre-cleaning/residual water treatment means 25 is controlled. The pre-cleaning/residual water treatment means 25 cleans the nozzle 1 by opening the solenoid valve 4 for a certain period of time t2 (for example, 7 seconds) after the "waste water treatment" by the waste water ON/OFF control means 21 is completed. The time t2 from the ON driving of the pre-cleaning/residual water treatment means 25 is configured to be counted by the pre-cleaning time control means 26. Then, the pre-cleaning/residual water treatment means 25 performs cleaning for this cleaning time t2.
If the time exceeds the preset time (e.g. 7 seconds), "
It is determined that there is an abnormality in the apparatus, and a pulse signal is issued to drive the electromagnetic valve 4 to "close", thereby interrupting the pre-cleaning and water discarding operations. When the pre-washing time control means 26 finishes within a predetermined time t2, the washing water discharging means 31 in the subsequent stage is maintained in a standby state via the washing signal detection means 29 and the washing control means 30, and the "butt washing" or "bidet washing" is performed. Cleaning switch operation means 2 for “Washing”
The structure is such that it is activated by waiting for the input of the "water discharging signal" from 8. The cleaning control means 30 controls and drives a flow rate adjustment motor 16 that controls the opening degree of a throttle valve 15 provided downstream of the water spouting electromagnetic valve 4 . At this time, the waiting time t3 is defined as the waiting time t3 from when the overflow by the pre-washing/residual water processing means 25 is finished until the "water discharging signal" is input from the washing switch operation means 28 for "butt washing" or "bidet washing". This waiting time t is counted by the control means 32.
3 exceeds the preset time (for example, 5 minutes),
It is determined that the temperature inside the water discharge pipe 17 has decreased, and the said waste water is turned ON/
A residual water treatment system driven by the OFF control means 21 is configured. In addition, the residual water treatment system of the above-mentioned embodiment judges the "decrease in the water temperature in the water discharge pipe 17" by a structure in which the standby time control means 32 measures the standby time t3, and then drives the waste hot water ON/OFF control means 21 again. I showed you what to do,
As shown in FIG. 2, a structure is adopted in which "a drop in water temperature in the water discharge pipe 17" is detected based on temperature information from a pre-cleaning water temperature detection means 27 provided in the water discharge pipe 17, and the waste hot water ON/OFF control means 21 is re-driven. Needless to say, it is also possible to do so, and furthermore, both structures can be installed together.

Next, the operation of the switch receiving mechanism in the sanitary washing device having the above configuration is shown in the operation flowchart of the entire sanitary washing device shown in FIG. 3 (the switch receiving mechanism is the part surrounded by the broken line R), and This will be explained according to the timing chart in FIG. (1) The seating detection means 20 arranged at the toilet seat position detects whether the user is sitting. (2) Open the solenoid valve 13 for draining hot water until the draining hot water temperature is detected to be 42°C, and perform “throwing hot water”. At this time, if the temperature does not reach 42°C within a preset time t1 (2 minutes), it is determined that "the external hot water supply equipment is out of order" and the hot water discharging operation is stopped. (3) After the operation in (2) above is completed, the thermovalve 6 of the electronic valve unit D is set to the temperature control position set during the previous use (at this time, the first time when the power is turned on is position). (4) At the same time as the operation in (3) above, nozzle 1 is
．． Extend by 5 mm, and adjust the water pressure by setting the throttle valve 15 to the minimum water discharge amount position using the flow rate adjustment motor 16, and after completing the setting operation, open the water discharge electromagnetic valve 4 to perform pre-cleaning for 7 seconds (t2). At this time, the electronic valve unit D controls and drives the mixing motor 7 to control the temperature of the thermovalve 6, so that the temperature is adjusted to the set temperature. (5) After the operation in (4) above is completed, the nozzle 1 is retracted, and the water force is adjusted by setting the throttle valve 15 to the maximum discharge amount position by the flow rate adjustment motor 16, and after setting the water force, the cleaning switch operating means 28 Waiting for the "butt washing" and "bidet washing" switches to be accepted. At this time, unless the cleaning control means 30 completes the operation (4), it operates to block input of the water discharging signal for "butt cleaning" or "bidet cleaning" from the cleaning switch operating means 28. (6) “Butt washing” or “
If the "Bidet Cleaning" switch is not pressed for 5 minutes, switch the thermo valve 6 of the electronic valve unit D to the mixing motor 7.
Fully open to the water side and perform the operation (2) above. (7) After the operation (6) above is completed, the thermovalve 6 of the electronic valve unit D is set to the temperature control position previously adjusted by the operation (4), and then the operation (6) is performed. (8) When the seating detection means 20 detects that the user is not seated, the following operations are performed. (9) If the "butt washing" or "bidet washing" is in progress, that operation is stopped and the mode becomes the same as when the "stop" switch is pressed. (10) To adjust the water force, the flow rate adjustment motor 16 is driven to set the throttle valve 15 to the maximum water discharge position. (11) The thermovalve 6 of the electronic valve unit D is fully opened to the water side.

[Effects of the Invention] Since the switch reception mechanism in the sanitary cleaning device according to the present invention is configured as described above, it is possible to perform pre-cleaning and
If residual water processing is not completed, the operation of "butt washing" or "bidet washing" from the water spout switch operation means will not be accepted, so hot water that remains in the water spout piping and cooled will not be discharged, making it comfortable at all times. This makes it possible to ensure a temperature of water discharged, and the effect after implementation of the present invention is extremely large.
