BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a control method of bidet with sterilizing function,

The present invention relates to a method for controlling a bidet with a bidet nozzle and a sterilizing function for sterilizing a pot with a bidet by sterilizing water. In particular, And a control method of a bidet equipped with a sterilizing function provided with a sterilizing function of sterilizing pottery provided with bidet by sterilizing water.

Generally, a bidet is used to wash anus or women's local area by washing water sprayed from a nozzle without using a toilet paper after using a toilet, and to dry the remaining water around the anus or the local area by hot air supplied when the drying function is performed As the interest in hygiene has increased recently, it has been widely used by both sexes.

When performing a cleaning operation or a bidet operation, the bidet projects a nozzle from the body of the bidet to spray the washing water. At this time, secretion falling from the user's body may be buried in the inner wall of the pottery provided with the nozzle or the bidet.

If the bidet is not used for a certain period of time with the discharge being applied to the nozzle, the discharge from the nozzle may adhere to the nozzle. In addition, in a pot with a bidet, if the toilet does not completely wash off the toilet, the toilet can be pushed against the inner wall of the toilet, and water is always stored in the toilet, so that various microorganisms can be inhabited and proliferated.

Therefore, many bidets are equipped with a sterilizing function to sterilize the nozzle or the pottery.

Referring to FIG. 2, the control unit 110 determines whether a seating of the user is detected (S200). That is, the control unit 110 receives the detection signal from the seating detection unit 160, and determines whether or not the user has been seated on the toilet seat using the input detection signal.

When the user's seating is detected, the control unit 110 determines whether a signal of a cleaning key or a bidet key is inputted from the operation key unit 170 (S202).

The control unit 110 increments the value of the operation count counter by one (S204), and then increments the value of the operation count counter by one (S204). If the cleaning key or the bidet key signal is input from the operation key unit 170, The setting operation time of the cleaning operation or the setting operation time of the bidet operation to be performed is determined according to the signal of the cleaning key or the bidet key (S206).

Here, the setting operation time of the cleaning operation and the setting operation time of the bidet operation may be set in advance in a memory (not shown) built in or externally installed in the control unit 110 have. Further, the setting operation time of the cleaning operation and the setting operation time of the bidet operation may be set to be the same, or the setting operation time of the cleaning operation and the setting operation time of the bidet operation may be set to be different from each other.

The controller 110 performs a cleaning operation or a bidet operation (S208), and cumulatively counts operation times for performing the cleaning operation or the bidet operation (S210).

In this state, the controller 110 determines whether or not the set operation time has elapsed (S212). If the set operation time has not elapsed, the controller 110 returns to the step S200 to detect the seating of the user, Counts an operation time counter when a signal of a key or a bidet key is input, counts the operation time, determines an operation time, and cumulatively counts an operation time for performing a cleaning or bidet operation while performing a cleaning or bidet operation .

Therefore, in the present invention, when the user repeatedly presses the cleansing key or the bidet key while repeatedly sitting on the toilet seat of the bidet, the number of times the cleansing key or the bidet key is pressed repeatedly is repeated And accumulate counts.

When the washing key or the bidet key signal is not inputted from the operation key unit 170 in the step S202, the controller 110 determines whether the washing operation or the bidet operation is currently performed (S214).

As a result of the determination, if the current cleaning operation or the bidet operation is not being performed, the control unit 110 returns to step S200 and repeats the operation of determining whether or not the seating is detected.

If it is determined in step S214 that the cleaning operation or the bidet operation is being performed, the controller 110 continues to perform the cleaning operation or the bidet operation in step S208. In step S210, And repeatedly performs the operation of determining whether or not the set operation time in the step S212 has elapsed.

When the set operation time in the step S212 has elapsed, the controller 110 stops the currently performed washing operation or the bidet operation (S216), stops the cumulative counting of the operation time (S218) The process returns to step S200.

If no seating is detected in step S200, the controller 110 determines whether the count value of the operation frequency counter is greater than a predetermined number (S220). If the count value of the operation frequency counter It is determined whether or not the cumulative operation time counted is equal to or greater than a predetermined number of times (S222).

The control unit 110 operates the sterilizing water generating unit 140 for a predetermined period of time to sterilize the sterilizing water for a preset time when the count value of the operation frequency counter is equal to or greater than a preset number of times, (S224).

When the predetermined time has elapsed and the generation of the sterilizing water is completed, the controller 110 performs sterilizing operation of the pot with the nozzle or bidet of the bidet using the sterilizing water (S226).

Here, sterilizing water generated by operating the sterilizing water generating unit 140 may cause various skin troubles including inflammation and the like when the sterilizing water is brought into contact with the user's skin, for example. Therefore, the time for performing the sterilizing operation of the pot with the nozzle or bidet of the bidet is set to be longer than the time when the sterilizing water generated by operating the sterilizing water generating unit 140 is discharged to the outside of the bidet and removed desirable.

When the sterilization operation using sterilized water is completed in step S226, the control unit 110 resets the count value of the operation time counter (S228), resets the count value that cumulatively counts the operation time, (S230), and returns to step S200 to repeat the operation of determining whether or not the seating is detected.
