Widely popular.
[0003]
The hot water cleaning apparatus is mainly composed of a hot water tank and a cleaning nozzle, and the cleaning water branched from the water pipe enters the hot water tank and is heated by a heating wire or the like, and a predetermined human body part is preset. After the temperature reaches a temperature that can be cleaned, the water is ejected from the cleaning nozzle toward the human body part. In the hot water tank, since it takes time to heat the cleaning water according to the cleaning instruction from the user, the heated cleaning water is always kept warm.
[0004]
The heating toilet seat device installs a heater inside the toilet seat, and heats the toilet seat to a predetermined temperature by energizing the heater. Although the toilet seat has a time difference depending on the season, it takes some time to heat from room temperature to a predetermined temperature, so it is always heated or kept warm, and no matter when the user uses the human body local washing device, I don't feel cold.
[0005]
The human body local cleaning apparatus described above has been developed with a power saving function due to the recent trend of environmental problems, and at the midnight when the human body local cleaning apparatus is rarely used, Electricity is saved by lowering the heating temperature of the toilet seat and the heating temperature of the toilet seat below the temperature set by the user.
[0006]
As a specific method of power saving, when the user presses a predetermined switch, regardless of the temperature set by the user, the energization to the hot water heater or the toilet seat heater is stopped. Various proposals have been made such as providing a sensor that can detect the user's seating on the toilet seat, and stopping energization of the warm water heater and the toilet seat heater or lowering the temperature by a predetermined temperature when not in use.
[0007]
[Problems to be solved by the invention]
However, when the user presses a predetermined switch, regardless of the temperature set by the user, the one that stops energizing the hot water heater or the toilet seat heater is effective when the device is not used for a long time. Although it is a means, when the user frequently uses the device, it takes about 5 to 10 minutes to heat the hot water and the toilet seat even if the power saving operation is cancelled. In addition, the user is troublesome to operate a predetermined switch.
[0008]
Sensors that can detect the user's seating are provided in advance in the toilet seat. When not in use, the hot water heater or the toilet seat heater that stops energization or drops to a specified temperature is used when the seat is re-sold and the warm water and toilet seat are cold. Give people discomfort.

Further, the user can recognize the temperature selected by the user with the hot water temperature display lamp or the toilet seat temperature display lamp.
[0021]
4 is a block diagram of the human body local cleaning apparatus shown in FIG. First, the operation of the hot water washing apparatus 130 for washing the human body part with hot water will be described. When the user depresses the bottom switch S2 of the operation panel 4, the electromagnetic valve control means 134 opens the water electromagnetic valve 100 to supply water to the hot water tank 101. Inside the hot water tank 101, water is heated using the hot water heater 102 so that hot water at a temperature selected by the user can always be ejected. When water is supplied to the hot water tank 101, Is extruded and ejected from the cleaning nozzle 5. A water amount control valve 104 is provided between the hot water tank 101 and the washing nozzle 5 so that the water amount can be adjusted as appropriate based on an instruction from the water amount control means 133.
[0022]
When controlling the temperature of the hot water in the hot water tank 101, the set temperature selected by the user with the hot water switch S4 is stored in the set temperature storage means 122 as set temperature data via the switch input unit 121 in the control device 120. Is done. At the time of use, the set temperature data is transmitted to the set temperature conversion means 126 as it is. On the other hand, the hot water temperature detected by the hot water temperature detection sensor 103 is stored in the detected temperature storage means 128 as temperature data. The set temperature comparison unit 127 compares the set temperature data with the temperature data described above, and transmits the result to the hot water heater overheating unit 131. The warm water heater heating means 131 that has received the result of the temperature comparison energizes the warm water heater 102 if the warm water temperature is lower than the set temperature, and stops energization if the warm water temperature is equal to or higher than the set temperature.
[0023]
Next, control of the heating toilet seat apparatus 1 will be described. During use, the temperature set by the user using the toilet seat switch S5 of the operation panel 4 is transmitted as set temperature data to the set temperature storage unit 122 and the set temperature conversion unit 126 via the switch input unit 121. On the other hand, the toilet seat temperature detected by the toilet seat temperature detection sensor 106 is stored in the detected temperature storage means 128 as temperature data. The set temperature comparison unit 127 compares the set temperature data and the toilet seat temperature data described above, and transmits the result to the toilet seat heater heating unit 132. Upon receipt of the temperature comparison result, the toilet seat heater heating means 132 energizes the toilet seat heater 105 if the temperature is lower than the set temperature, and stops energization if the toilet seat temperature is equal to or higher than the set temperature.
[0024]
A human body detection means is demonstrated. The human body detection means is provided because hot water is not ejected even if an infant or the like presses the switch or accidentally presses the switch when cleaning the operation panel 4. In this embodiment, the human body detecting means is provided with a micro switch 135 in the heating toilet seat device 1 as shown in FIG. When the user sits on the toilet seat, the micro switch 135 is arranged so as to abut against the toilet bowl by a load and to be activated (turned on). The operation of the butt switch S2 and the bidet switch S3 is accepted only when the above-described micro switch is operating.
[0025]
The temperature control when the hot water washing apparatus 130 and the heating toilet seat apparatus 1 are not used in the present embodiment will be described in detail below. The human body detection frequency measuring means 123 in FIG. 4 is configured to count the number of times the user is seated within a predetermined time. More specifically, the number of times the micro switch 135 is turned on (operated) from off (non-actuated) for a predetermined time (one day in this embodiment) is measured. However, in this embodiment, the number of human body detections is updated as needed by taking the average value of the data for the last week. This is to cope with changes in the user's life pattern.
[0026]
The timer 124 is configured to operate from the time when the above-described micro switch 135 is turned off, and measures an operation time such as a decrease in the set temperature, an increase in temperature, and a heater stop.
[0027]
FIG. 5 is a diagram showing the relationship between the usage frequency of the apparatus and the operation time. The first operation time is the time from when the user leaves the heated toilet seat device 1 until the energization of the heater is stopped. The second operation time is a time for stopping energization of the heater, and the third operation time indicates a time until the user returns to the set temperature set last time after resuming energization to the heater.
[0028]
For example, the operation when the usage frequency is low (0 to 5 times / day) will be described. When the user's sitting is detected, the energization of the heater is immediately stopped. Thereafter, energization to the heaters of the hot water washing device and the heating toilet seat device is stopped for 200 minutes. After the elapse of 200 minutes, the set temperature is converted by the set temperature conversion means.
[0029]
FIG. 6 shows the relationship between the operation time and the set temperature when the previous user sets the temperature to high (40 ° C.). Conversion is performed so that the set temperature rises in increments of 5 ° C. every 10 minutes. When the user is seated within the third operation time, the set temperature conversion means immediately converts to the previous set temperature, so that the desired hot water and toilet seat temperature can be obtained in a short time. Needless to say, when sitting after the third operating time has elapsed, the same hot water and toilet seat temperature as in the previous time can be obtained.
[0030]
A case of frequent use (31 times / day or more) will be described. When the control device 120 detects the user's sitting, as shown in FIG. 7, conversion is performed so that the set temperature drops every 5 minutes in increments of 5 ° C. After the first operation time has elapsed, the temperature returns to the temperature (40 ° C.) previously set by the user. When the frequency of use is high, the heater energization prohibition time is set to 0. Therefore, even if the user frequently uses it, there is no discomfort that the washing water and the toilet seat are cold.
[0031]
FIG. 8 is a graph showing the relationship between the temperature of washing water and toilet seat and time when the usage frequency is low, and FIG. 9 is a graph showing the relationship between temperature and time of washing water and toilet seat when the usage frequency is high. . As shown in FIGS. 8 and 9, the control may be performed while changing the set temperature of the wash water, the toilet seat, and the operation time.
[0032]
【The invention's effect】
As described above, according to the present invention, when the apparatus is not used, the set temperature is lowered or the energization to the heater is stopped, so that the apparatus can save energy. In addition, since the heater is switched on according to the frequency of use, significant energy savings can be achieved when the frequency of use is low, and when the frequency of use is high, the wash water or toilet seat is cold when used again. A comfortable device without discomfort can be provided. Since the calculation of the usage frequency is automatically performed by the human body detection means, there is no troublesome operation of an extra switch. Furthermore, the number of assembly parts is not increased as compared to the conventional case, and it is not necessary to secure a space for implementing the power saving function, so that the product cost does not increase.
