Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a sanitary cleaning device for cleaning private parts of a human body after defecating by discharging cleaning water.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of the structure of a conventional sanitary cleaning device related to the present invention will be described with reference to FIG. 1 is a toilet bowl, 2 is a toilet that stores water for flushing the inside of the toilet bowl 1, 3 is a toilet seat installed on the toilet bowl 1, and 4 is a flusher that discharges cleansing water to the private parts of the human body sitting on the toilet seat 3. a nozzle; 5 is a water filter into which the water stored in the distern is submerged; 6 is a pump that sucks water from the water filter and pumps it to the cleaning nozzle 4; 7 is a sensor that detects the temperature of the cleaning water; 8 A heater is a heating means for heating the wash water pumped by the pump 6, and a heat exchanger 9 transfers the heat of the heater 9 to the wash water being pumped to instantaneously heat it. 10 is a cleaning switch; 11 is a setting means for setting the amount of cleaning water; 12 is a setting means for setting the temperature of the cleaning water; A control means for controlling the amount of electricity supplied to the pump 6 to instantly set the temperature to a desired temperature and energizing the pump 6; a storage box 14 installed at the rear of the toilet seat 3 and housing the pump 6, the control means 13, etc.; be.

In the above configuration, when the control means 13 confirms that the washing switch is turned on, it energizes the pump 6 so that the amount of washing water corresponds to the setting value of the setting means 11, and at the same time energizes the pump 6 so that the amount of washing water corresponds to the setting value of the setting means 12. The amount of electricity supplied to the heater 8 is controlled so as to maintain the cleaning temperature, and the cleaning water is discharged from the cleaning nozzle to the private parts of the human body.

However, in the above-mentioned conventional sanitary washing device, after the washing switch 10 is turned on, the pump 6 operates while securing the desired torque, and when the washing water is sent, there is a certain degree of pressure loss and resistance in the piping system. A delay in response occurs. The temperature of the washed water in the shattered heat exchanger depends on the flow rate therein, and if the heater 8 is turned on immediately when the wash switch 10 is turned on, the temperature of the washed water in the heat exchanger will increase due to a delay in the response of the pump. The stagnant cleaning water turns into high-temperature cleaning water, which has the drawback of causing a risk of burns if it is released into the private parts of the human body. In addition, the heater 8 detects high-temperature cleaning water.
When the power supply to the pump 6 is turned off, the pump 6 has already secured the desired torque, causing a problem of overshoot at the start of cleaning.

OBJECTS OF THE INVENTION The present invention solves these conventional drawbacks and aims to prevent generation of high-temperature washing water at the start of washing.

DESCRIPTION OF THE INVENTION To achieve this object, the present invention comprises a control means that energizes the heating means with a certain delay when the pump is activated, such as at the start of cleaning. With this configuration, at the start of cleaning, the heating means is energized after the unwashed pop obtains the desired torque and the cleaning water flows, so that the stagnant cleaning water does not reach a high temperature.

Deception of the Actual Sister Example FIG. 2 is a block diagram of the control means in one embodiment of the present invention. 15 is a power supply, 16 is a pump energizing circuit, 17 is a heater energizing circuit, and 18 is a delay timer located in the energizing path of the heater 8.

In the above configuration, when the cleaning switch 10 is turned on at the start of cleaning, the pump energizing circuit 16 is energized, the pump 6 is energized, and the cleaning water is sent to the cleaning nozzle. However, due to the action of the delay timer 18, the heater energizing circuit 17 is again not activated and the heater 8 is not energized. After a certain period of time, the delay timer 18 is turned on, the heater energizing circuit 17 is activated, and while monitoring the set values of the sensor 7 and setting means 12, the amount of electricity supplied to the heater 8 is controlled, and the cleaning water at the desired temperature is supplied. It is something that is emitted. The shorter the delay time of the delay timer 18, the better from the viewpoint of usability of this device.
It is necessary to set a time longer than the maximum time including response delay, pressure loss including piping system, and resistance, and usually 0.5 to 1
It's about seconds.

Although the delay timer is connected before the heater energizing circuit in the actual example, the same effect can be obtained even if the delay timer is connected after the heater energizing circuit.

Effect of the invention According to the sanitary cleaning device of the present invention, the following effects can be obtained.

Since the control means is configured to energize the heating means with a certain delay when the pump is activated, the cleaning water stagnant in the piping system will not reach a high temperature due to a delay in the pump etc. at the start of cleaning, and therefore high-temperature cleaning will not occur. This prevents water from being released locally. Furthermore, since there is no longer any instantaneous exposure to high temperatures, there is no deterioration of the heat exchanger and the reliability of the device is increased.
