Note that reference numeral 30 in FIG. 2 denotes a cleaning liquid holding unit.
[0016]
As shown in FIG. 3, the local cleaning device main body 2 stores water from a water supply valve 15 for supplying / stopping water from the water supply port 14 and water from the water supply port 14, and heats the water by a hot water heater 5a.

And a water pump 19 for conveying the water in the hot water tank 6 to the washing nozzle 16.
[0017]
Here, in the hot water tank 6, there are a hot water heater 5 a that is a hot water heating means 5 for heating hot water sprayed to a local part of the human body, a hot water thermistor (not shown) for detecting the water temperature, and a hot water tank. A water level detection sensor (not shown) for detecting full water 6 is arranged.
[0018]
As shown in FIG. 5, the cleaning nozzle 16 includes a butt cleaning nozzle 16a, a bidet cleaning nozzle 16b, a nozzle cleaning nozzle 16c for cleaning the butt cleaning nozzle 16a and the bidet cleaning nozzle 16b, and a toilet bowl for cleaning the inner surface of the toilet bowl.

By switching the flow path with this rotary switching valve 17, hot water from the hot water tank 6 is It can be ejected from the hip cleaning nozzle 16a or the bidet cleaning nozzle 16b. In addition, the toilet cleaning nozzle 16d can be sprayed on the inner surface of the toilet bowl or can be sprayed from the nozzle cleaning nozzle 16c toward the cleaning nozzle 16.
[0019]
The water pump 19 functions to change the cleaning flow rate according to the control signal input from the control unit 7 and keep it constant. The means for changing the cleaning flow rate may be controlled using a motor instead of controlling the water pump 19. In this case, the amount of water can be changed by changing the cross-sectional area of the flow path in accordance with the signal from the control unit 7. Similarly, when an electromagnetic valve is used, the amount of water can be changed by changing the channel area. In addition, the water pump 19 of this embodiment may be omitted. In this case, the electromagnetic water supply valve 15 can be opened by operating the cleaning operation key, and the cleaning water can be directly fed by the supply water pressure. The temperature of the hot water is maintained at the temperature set by the user by detecting the water temperature with a hot water thermistor and energizing the hot water heater 5a.
[0020]
Further, as shown in FIG. 2, the local cleaning device main body 2 includes a seating detection sensor 9 for detecting the seating of the user, and an entrance / exit detection sensor 8 for detecting the entrance / exit of the person into the toilet. A room temperature detection sensor 31 comprising a thermistor for detecting the room temperature is arranged. The entrance / exit detection sensor 8 is composed of, for example, an infrared sensor or an ultrasonic sensor.
[0021]
Next, as shown in FIG. 4, the heating toilet seat includes a toilet seat body 4a, a base (not shown), a toilet seat heater 3a, a heat equalizing member 20, and the like. The toilet seat body 4a is made of PP resin, and is formed in an arc shape having a thickness of about 3 mm so as to withstand the seating load of the human body. The base is fixed so as to provide a space between the toilet seat body 4a. A sheet made of a metal having a high thermal conductivity (for example, aluminum) having a thickness of about several tens to several hundreds μm is used for the soaking member 20, and is fixed to the back surface of the toilet seat body 4a with an adhesive sheet. A toilet seat heater 3a, which is a toilet seat heating means 3 for heating the seating surface of the toilet seat body 4a, is disposed inside the toilet seat body 4a. The toilet seat heater 3a is composed of, for example, a PVC-coated heater wire, and is fixed to the heat equalizing member 20 by adhesion or the like. As the toilet seat heater 3a, for example, one having an electric power of about 50 W is used. The toilet seat heater 3a is electrically connected to a circuit on the local cleaning device main body 2 side, and is heated by Joule heat generated when energized. The heat generated from the toilet seat heater 3a is diffused laterally by the soaking member 20, and is transmitted to the surface of the toilet seat 4 by heat conduction of the resin of the toilet seat body 4a. A thermistor (not shown) is built in the toilet seat 4, detects the temperature of the toilet seat 4, and controls the energization of the toilet seat heater 3a by the control circuit. The toilet seat 4 is fixed to the local cleaning device main body 2 by, for example, a detachable hinge member (not shown). When cleaning the toilet seat 4, the toilet seat 4 can be separated from the local cleaning device main body 2 and wiped with a cloth or the like.
[0022]
The toilet seat 4 is covered with a toilet lid 11 shown in FIG. The toilet lid 11 is connected to a toilet lid automatic opening / closing mechanism 12 (FIG. 2 (b)) arranged on the local cleaning device main body 2 side, and is automatically linked to ON / OFF of a signal from the entrance / exit detection sensor 8, for example. In this example, the toilet lid automatic opening / closing mechanism 12 is set to operate effectively even in a state where a power saving mode described later is being implemented.
[0023]
Next, the operation unit 13 includes a toilet seat operation unit, a washing operation unit, a power saving operation unit, and the like that are not illustrated. The toilet seat operation part is provided with a toilet seat temperature operation key for changing the toilet seat temperature, and the washing operation part has a washing mode operation key for operating the washing mode and a washing for changing the temperature of the washing water. A temperature operation key and a cleaning flow rate operation key for changing the cleaning flow rate during cleaning are arranged. When the user performs these key operations, key input information is transmitted to the control unit 7. A power saving mode key is arranged in the power saving operation unit. When the power saving mode key is turned on, the control unit 7 automatically executes the power saving mode according to the control program of the microcomputer.
[0024]
Here, a transmission means for transmitting a de-energization maintenance signal for maintaining either one or both of the toilet seat heater 3a and the hot water heater 5a in a non-energized state is provided, and the control unit 7 is configured to The power saving mode is performed when the energization maintaining signal is input. In this example, the entrance / exit detection sensor 8 for detecting the entrance / exit of a human body into the toilet also serves as a transmission means, and the exit signal from the entrance / exit detection sensor 8 is used as a de-energization maintenance signal. That is, in FIG. 1, when the control unit 7 is in the power saving mode, when the exit signal from the entrance / exit detection sensor 8 is input to the control unit 7, it is recognized as a non-energization maintaining signal in the control unit 7. The toilet seat heater 3a and the hot water heater 5a are each kept in a non-energized state, and the toilet seat heater 3a is returned to an energized state when an entry signal from the entry / exit detection sensor 8 is detected in a non-energized state. Next, the warm water heater 5a is returned to the energized state when a seating signal from the seating detection sensor 9 for detecting that the human body is seated on the toilet seat 4 is detected. The normal mode in FIG. 1 is a mode for controlling the energized state for 24 hours as in the conventional case, and the user can arbitrarily select and set the power saving mode and the normal mode by the operation unit 13. Yes.
[0025]
Next, an example of actual operation when the user selects the power saving mode with the power saving mode key will be described with reference to FIG. When the user enters the toilet, the entrance / exit detection sensor 8 detects entry, the toilet seat heater 3a returns to the energized state, and the toilet seat temperature rises as shown by the line L1 in FIG. When seated on the toilet seat 4, seating is detected by the seating detection sensor 9, the warm water heater 5a returns to the energized state, and the warm water temperature rises as shown by the line L2 in FIG.
Then, the toilet cleaning mode is executed in conjunction with the seating, and the hot water is ejected from the toilet cleaning nozzle 16d to the toilet. Toilet cleaning is performed for about 1 second, for example. Further, when the butt cleaning mode or the bidet cleaning mode is selected after sitting, warm water is ejected from the butt nozzle or the bidet nozzle toward the local area. After the cleaning, the nozzle cleaning mode is executed for several seconds in conjunction with the user leaving the seat. The rinse water at this time is ejected from the nozzle cleaning nozzle 16 c toward the cleaning nozzle 16. After that, when the user leaves the room, the exit signal is detected by the exit signal from the entrance / exit detection sensor 8, and the energization to the toilet seat heater 3a and the hot water heater 5a is stopped, as shown by lines L3 and L4 in FIG. The temperature of the toilet seat 4 and the hot water is lowered. This non-energized state is maintained until the next use. The power saving mode can be canceled by operating the switch and can be switched to the normal mode.
[0026]
Thus, in the local cleaning device 1 having the above-described configuration, the toilet seat heater 3a and the hot water heater 5a can be maintained in a non-energized state in the power saving mode except during the use time period, and power can be saved. Moreover, since the toilet seat heater 3a is returned to the energized state at the same time as entering the room during use, the toilet seat 4 does not feel cold when seated. In addition, since the warm water heater 5a is returned to the energized state when sitting, the wash water is sufficiently heated from the time of entering the room until the buttocks cleaning is performed, and the warm water does not feel cold at the time of washing. Can be washed with warm water.
[0027]
Furthermore, since it is not seated at the time of male urination, the warm water heater 5a is maintained in a non-energized state, and a higher power saving effect can be obtained. Further, in this example, since the operation of the toilet lid automatic opening / closing mechanism 12 is effective even in the power saving mode, the toilet lid is based on the entry signal from the entry / exit detection sensor 8 even in the power saving mode. 11 can be opened automatically.
[0028]
Further, since the toilet seat body 4a and the hot water have a heat capacity, it takes several tens of seconds to several minutes until the temperature set by the user after the hot water heater 5a and the toilet seat heater 3a are energized. Necessary. Since several minutes elapse from the time of entering the room until the buttocks are washed, the hot water is heated to almost the set temperature. However, since the toilet seat 4 is seated about 10 seconds after entering the room, it may not be sufficiently heated. Therefore, in the power saving mode, only the hot water heater 5a may be in a non-energized state as shown by a line L6 in FIG. At this time, the toilet seat heater 3a may not be in a completely non-energized state, but may be maintained at a minimum temperature (for example, around 20 ° C.) that does not feel cold as indicated by a line L5 in FIG. In this case, the toilet seat 4 can be quickly heated to a predetermined temperature particularly at low temperatures such as in the cold season or at midnight.
[0029]
In addition, only when the room temperature detected by the room temperature thermistor is equal to or higher than a certain value (for example, 20 ° C.), the hot water heater 5a and the toilet seat heater 3a are de-energized. You may make it keep in a minimum temperature whether it will not be in a non-energized state. In this case, since the power saving mode functions effectively when the room temperature detected by the room temperature detection sensor 31 is a certain value or more, the toilet seat heater 3a and the warm water heater 5a are not energized when the room temperature is a certain value or more. Even when the toilet seat 4 and the warm water are not cooled, the warm water and the toilet seat 4 do not feel cold even when the user enters the room while the power is turned off.
[0030]
In the above-described embodiment, the toilet seat heater 3a and the hot water heater 5a are de-energized in conjunction with the exit signal of the entrance / exit detection sensor 8 shown in FIG. 2, but as another example, it is provided in the local cleaning device 1 or the remote controller. It may be made to interlock | cooperate with the signal transmitted in conjunction with operation of the off switch 10 made. In this case, the off switch 10 also serves as a transmission means, and a signal transmitted in conjunction with the operation of the off switch 10 is a non-energization maintaining signal. As another example, as shown by lines L7 and L8 in FIG. 7, it may be linked to a seating signal from a seating detection sensor 9 for detecting the seating of the human body on the toilet seat 4. In this case, the seating detection sensor 9 also serves as a transmission means, and the separation signal from the seating detection sensor 9 becomes a non-energization maintenance signal. Thus, since the off switch 10 or the seating detection sensor 9 can be effectively used as a means for transmitting the de-energization maintaining signal, it is possible to prevent an increase in the number of parts of the transmitting means, and to reduce costs and simplify the assembly process due to a decrease in assembly parts. In addition, it is not necessary to secure a space for incorporating new parts, and it is easy to reduce the cost and size of the local cleaning device 1. In addition, when the separation signal is set to the de-energization maintenance signal, the power saving mode can be performed earlier, so that the hot water heater 5a and the toilet seat heater 3a can be de-energized earlier, and the power saving effect can be further enhanced. It can be done.
[0031]
Further, as shown in FIG. 8, after a predetermined time T1 has elapsed since the entry signal of the entry / exit sensor, the separation signal of the seating detection sensor 9, or the signal by the operation of the remote control off switch 10 is input, The temperature of the toilet seat 4 and the hot water is controlled so as to be lowered to a predetermined temperature as shown by the lines L9 and L10 in FIG. 8, and then the toilet seat heater 3a is displayed as indicated by the lines L11 and L12 in FIG. The hot water heater 5a may be controlled so as to be kept in a non-energized state. Other configurations are the same as those in FIG. Thus, when a plurality of people use continuously, even if the previous person sets power saving, the next person does not feel uncomfortable with the temperature of the toilet seat 4 or the hot water. After that, after a certain period of time has passed, it automatically goes into a non-energized state. Therefore, if the toilet is not used for a long time from the previous use to the next use, it automatically goes into a non-energized state, saving power. . In addition, in FIG. 8, although the fall width of the toilet seat 4 temperature after the fixed time progress was made into the same fall width as warm water, it is good also as a different fall width.
[0032]
Further, as a modification of FIG. 8 described above, the control for lowering the temperature of the toilet seat 4 and the hot water to a predetermined temperature is omitted, and the toilet seat heater 3a and / or The hot water heater 5a may be maintained in a non-energized state, and in this case, power can be saved at an earlier timing.
[0033]
In the power saving mode of the above-described embodiment, only the toilet seat heater 3a is returned to the energized state when entry is detected in a state where de-energization is maintained, and the hot water heater 5a is returned to the energized state when seating is detected. However, apart from this, when entering the room while maintaining de-energization, another power-saving mode is set to return both the toilet seat heater 3a and the hot water heater 5a to the energized state. The mode selection means for selecting these two different power saving modes can be arbitrarily selected and operated by the operation unit 13.
[0034]
【The invention's effect】
As described above, the local cleaning device of the present invention can save electric power by maintaining the toilet seat heating means and the hot water heating means in a non-energized state in the power saving mode except during the use time period. On the other hand, the toilet seat and the warm water at the time of washing can be used comfortably without feeling cold during use, and the warm water heating means is maintained in a non-energized state because it is not seated during the men's urine, and a higher power saving effect can be obtained.
