[0003] The control means includes a normal mode in which the washing water in the washing water tank is maintained at a predetermined appropriate temperature set value, and a control mode in which the washing water in the washing water tank is maintained at a relatively low temperature set value lower than the appropriate temperature set value. By doing so, a power saving mode in which the power consumed by the heating means is saved can be appropriately set by the user. The normal mode is set when the frequency of use is high in the daytime or the like, and the power saving mode is set when the frequency of use is low in the night or the like.

FIG. 7 shows a temperature change of the washing water in the washing water tank when the user uses the human body local cleaning device in the power saving mode. In the drawing, the graph shown by the solid line is the washing water temperature in the washing water tank. According to this, the cleaning water temperature is maintained at the low temperature set value when the cleaning device is not used. In this state, when the first user enters the toilet room and opens the toilet lid, the electric heater in the washing water tank is energized to heat the washing water. As a result, the washing water temperature gradually increases from the low temperature set value to the appropriate temperature set value. Next, when the cleaning of the human body part is started, the heated warm water is jetted from the cleaning means. In this case, at the start of cleaning, the temperature of the cleaning water often does not rise to the appropriate temperature setting value, and the user cleans the human body part with the cleaning water at a temperature lower than the appropriate temperature. In addition, at the time of washing, since cold water is supplied into the washing tank, the washing water temperature gradually decreases,

Here, the case where the midnight is set to the power saving mode and the human body local cleaning device is used from the morning is considered, and even if the first user cleans the human body local part with cleaning water having a temperature lower than an appropriate temperature, In many cases, the user himself recognizes that the device was in the power saving mode before that time, and there is not much dissatisfaction. However,
Even when the second user cleans the body part of the human body, the temperature of the cleaning water is often lower than an appropriate temperature. In this case, the user often recognizes that the cleaning device has been used previously and that the cleaning water has already been heated, and contrary to this recognition, the cleaning is performed with relatively low-temperature cleaning water. Therefore, there is a problem that the user feels discomfort.

[0006] Therefore, the present invention has been made in view of the above-described circumstances, and in the case of using a continuous cleaning device in the power saving mode in a human body cleaning device, the second person uses cleaning water having a temperature close to an appropriate temperature. It is an object of the present invention to provide a human body part cleaning apparatus capable of cleaning a human body part.

It is possible to transfer it to.

In the human body local cleaning device 4 having the above configuration,
When the user presses a hot water switch (not shown) on the operation panel 45, the microcomputer 7 detects this and recognizes that the current mode is the hot water mode. In the warm water mode, the temperature of the washing water in the washing water tank 433 can be controlled.

In the warm water mode, the microcomputer 7 normally executes a normal mode in which the temperature of the washing water in the washing water tank 433 is maintained at a predetermined appropriate temperature. In the normal mode, a predetermined appropriate temperature determined in advance, for example, 3
A proper temperature control for maintaining the temperature of the washing water at 9.5 ° C. is performed.

FIG. 4 is a flowchart relating to control of the temperature of the cleaning water when the cleaning device is used in the power saving mode. Next, the operation of the microcomputer 7 in the power saving mode will be described with reference to FIG. In the figure, first, when the power saving mode is selected by the user, 0 is input to N as an initial value in step 101. Next, in step 102, it is determined whether the toilet lid is closed. If the toilet lid is open, the process proceeds to step 106, where the microcomputer 7 outputs a command for executing the appropriate temperature control for maintaining the washing water at an appropriate temperature, and returns to step 101. If the toilet lid is closed in step 102, the process proceeds to step 103, where it is determined whether or not N = 0.
If N = 0 is obtained as the initial value in step 101, the process proceeds to step 104. In step 104,
Temperature t of the washing water in the washing water tank detected by the hot water sensor 8, greater or not than a predetermined appropriate temperature set value t ₀ is determined. If t ≦ t _0, the process proceeds to step 108, where the microcomputer outputs a command to execute the appropriate temperature control for maintaining the washing water at an appropriate temperature, and returns to step 104.

= 1, the determination in step 103 (N =
(If it is 0) or not, the process goes to step 107. Then, in step 107, the microcomputer 7 outputs a command to execute low-temperature control for maintaining the cleaning water at a low temperature, and returns to step 102.

FIG. 5 shows a cleaning tank 433 when the user continuously uses the human body local cleaning device 4 in the power saving mode.
4 is a graph showing a change in temperature of cleaning water in the inside. With reference to FIG. 4 and FIG. 5, the temperature control of the washing water when the human body part cleaning device 4 is used in the power saving mode will be described.

First, in the power saving mode and when the toilet lid 42 is closed, the human body local cleaning device 4 is not used,
The microcomputer 7 controls the low temperature setting of the cleaning water, and the temperature of the cleaning water in the cleaning water tank 433 is maintained at the low temperature setting value (step 107). In this state, 1
When the second user enters the toilet room and opens the toilet lid 42,
The microcomputer 7 controls the appropriate temperature of the washing water, and starts increasing the temperature of the washing water toward an appropriate temperature set value by heating the washing water (step 102 to step 106). Next, when the cleaning of the human body part is started, the heated warm water is jetted from the cleaning means. In this case, at the start of cleaning, the temperature of the cleaning water often does not rise to the appropriate temperature setting value, and the user cleans the human body part with the cleaning water at a temperature lower than the appropriate temperature. Further, at the time of cleaning, since cold water is supplied into the cleaning tank 433, the temperature of the cleaning water gradually decreases, and sometimes drops to a temperature below the low temperature set value. Next, when the washing is completed and the toilet lid 42 is closed, the temperature of the washing water gradually increases and is heated to an appropriate temperature set value (Step 102-Step 103-Step 104-Step 108). Once heated to the appropriate temperature setting value, the microcomputer performs low-temperature control of the washing water (Step 104-Step 105-Step 103-Step 107). Therefore, the energization of the hot water heater 5 is stopped. As a result, the temperature of the washing water gradually decreases due to natural cooling. When the second user enters the toilet room and opens the toilet lid 42 during the natural cooling, the washing water is again controlled to an appropriate temperature and is heated to an appropriate temperature set value (step 102 to step 106). In this case, the wash water has been once raised to the appropriate temperature set value, and when the toilet lid 42 is opened, the temperature of the wash water has only slightly decreased from the appropriate temperature set value during natural cooling. The water immediately rises to the optimum temperature setting. When the temperature reaches the appropriate temperature set value, the washing water temperature is maintained at the appropriate temperature set value (step 106). In this state, when washing is started, heated warm water is jetted from the washing means. In this case, at the start of cleaning, the temperature of the cleaning water often rises to the appropriate temperature set value, and the user can comfortably clean the human body part with the cleaning water near the appropriate temperature set value. Further, at the time of cleaning, since cold water is supplied into the cleaning tank 433, the temperature of the cleaning water gradually decreases. Next, when the washing is completed and the toilet lid 42 is closed, the temperature of the washing water gradually rises and is heated to an appropriate temperature set value (step 102-).
Step 103-Step 104-Step 108).
When the temperature rises to the appropriate temperature set value, the microcomputer performs low temperature control of the washing water (Step 104-Step 1).
05-step 103-step 107). Therefore, the power supply to the hot water heater 5 is stopped, and the cleaning water is allowed to cool naturally.

As described above, in the power saving mode,
After the first user performs cleaning, the temperature of the cleaning water in the cleaning tank 433 is temporarily increased to an appropriate temperature set value.
The second and subsequent users can comfortably wash with the washing water near the appropriate temperature set value at the time of washing, and there is no complaint due to the low washing water temperature.

In the flowchart described above, steps 101, 103, 104, 105 and 108 are commands for temporarily raising the temperature of the washing water in the washing water tank to an appropriate temperature after washing.

As shown in the above flowchart,
In this example, the open / close state of the toilet lid (step 1) indicates whether the human body local cleaning device is in use or not in use during the power saving mode.
02), instead of the open / closed state of the toilet lid, the cleaning device determines whether or not the user is seated on the toilet seat by the seating sensor or whether or not the user enters the toilet room. May be used as a criterion for determining whether the device is not in use.

FIG. 6 shows a control flowchart in a conventional power saving mode for comparison. As can be seen, during the power saving mode, the microcomputer determines whether the toilet lid is closed. When the toilet lid is open, it is regarded as being used, and an appropriate temperature control command is output to try to maintain the washing water at an appropriate temperature. When the toilet lid is closed, it is regarded as not being used, and a low-temperature control command is output to try to keep the washing water at a low temperature.

As described above, the human body local cleaning apparatus 4 of the present embodiment includes the main body case 44 mounted on the toilet bowl 2, the cleaning water tank 433 stored in the main body case 44, and the cleaning water tank 433 in the cleaning water tank 433. Washing means such as a local washing nozzle 46 for washing the human body part by jetting the supplied washing water and washing the supplied washing water, and washing water in the washing water tank 433 by being energized from the power supply unit 6. And a microcomputer 7 for controlling the amount of electricity supplied to the hot water heater 5. The microcomputer 7 reduces the temperature of the washing water in the washing water tank 433 to a predetermined temperature lower than a predetermined appropriate temperature. In this power saving mode, the user cleans a human body part, and then performs cleaning. Since those to increase the temperature temporarily to a suitable temperature setting value, the first person of the user human private cleaning device 4
Is used, the temperature of the washing water in the washing water tank 433 is once increased to an appropriate temperature by a control command of the microcomputer 7. Then, when the second user uses the human body part cleaning device 4 in this state, the cleaning water that has once risen to an appropriate temperature is jetted to wash the human body part. As described above, when the second and subsequent users use the human body part cleaning device 4, the cleaning water that has once risen to an appropriate temperature gushes and cleans the human body part, so that when the temperature of the washing water is close to the appropriate temperature. The temperature of the washing water is low, and no complaints are generated.
