The present invention relates to a hot water scrubber, and more particularly, to an apparatus and method for controlling a toilet seat heater driving of a hot water scrubber capable of reducing the power consumption of the toilet seat heater.

Figure 1 is a schematic perspective view of a typical hot water scrubber. As shown in FIG. 1, the hot water washer is well connected to the left side. The toilet bowl 2 is disposed on the center portion of the toilet seat main body 1, and the spray nozzle 5) are installed so as to extend and retreat across the toilet bowl. On the upper portion of the toilet bowl (2), there is formed a left seat mounting part (2) on which the toilet seat (3) is seated when the toilet seat (2) is used. On one side of the main body 1, an operation key for operating operation of the hot water scrubber and an operation display section 7 for displaying the operation state of the hot water scrubber are arranged. On the rear side of the main body 1, A full-length endoscope 6 to which various electrical and mechanical parts constituting the mechanism, the washing water heating mechanism, and the hot air generating mechanism are mounted.

In the above-described configuration, the toilet seat 3 is typically made of a rubber material, and a seizure-sensing device 8 for sensing the seating of the human body is provided at the lower portion thereof. . In addition, a heater (not shown) is provided inside the toilet seat 20 to heat the toilet seat 3 to a predetermined temperature, thereby enabling the user to feel warmth when seated, thereby enhancing the feeling of use.

However, in the hot water washer of the above-described configuration, the toilet seat heater is kept energized at all times in the state where the power source is applied, so that the toilet seat is heated. This is because the heater is unnecessarily driven even when the user is not using it, There is a problem that power is wasted.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide an air conditioner which is capable of preventing waste of power consumption by turning off the driving of the toilet seat heater when the user does not use the hot- And a method of controlling the seat-mounted heater of a hot water washer.

In order to achieve the above object, a toilet seat driv- ing controller of a hot water scrubber according to the present invention is a hot water scrubber for performing a control operation with a seizure detection unit for detecting whether or not a user seated on a toilet seat, A time counting unit for counting a seating period of an occupant detected by the seated position detecting unit, and a controller for comparing the seating period of the user counted by the time counting unit with a predetermined reference time to drive the toilet seat heater And a microprocessor for controlling the microprocessor.

A method of controlling a driving of a toilet seat heater of a hot water scrubber according to the present invention is a method for controlling the driving of a toilet seat heater in a hot water scrubber equipped with a seat occupant detection unit for detecting whether or not a user is seated, a toilet seat heater for heating a toilet seat at a predetermined temperature, The method comprising the steps of: driving the toilet seat heater when the power is applied, detecting whether or not the user is seated; resetting the counted time when seating is detected as a result of detecting the seating position, Comparing the increased count value with a preset predetermined reference time, and turning off the driving of the toilet seat heater when the count value is equal to or greater than a predetermined reference time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, the schematic configuration of the hot water scrubber according to the present invention is as shown in FIG. 1, and a detailed description thereof will be omitted. FIG. 2 is a control block diagram showing a configuration of a hot water scrubber according to the present invention. FIG. As shown in FIG. 2, a microprocessor 10 for controlling the overall operation of the hot water scrubber, a power supply unit 11 for supplying a driving power to the microprocessor 10, a function selector for selecting all functions of the hot water scrubber, A nozzle motor driving unit 914 for driving the nozzle forward / backward motor (not shown) for advancing and retracting the injection nozzle to a predetermined position, a blower motor (not shown) for driving a blower motor A display unit 15 for displaying the current operation state of the hot water washer, a start-up detection unit 8 for sensing whether or not the user is seated in the toilet seat 3, and a toilet seat 3 to a predetermined temperature A toilet seat heater driving unit 13 for forming a toilet seat heater (not shown), and a time counting unit 12 for counting a seating period of a user while the toilet seat heater is driven.

For example, in the case of the weight detecting sensor, a change in resistance and voltage due to a change in weight due to seating of a user is sensed, It is determined whether or not the user is seated on the basis thereof. Therefore, when the seating detection unit 8 detects the seating of the user, the time counting unit 12 initializes the counted time and starts counting from the beginning. In addition, in the microprocessor 10, when any one of the cases where the user's seated position by the seated-seat detection unit 8 is detected and the time counted by the time counting unit 12 is less than the predetermined reference time is satisfied, The driving signal is outputted to the heater driving unit 13 to drive the toilet seat heater. On the other hand, when the time counted by the time counting unit 12 is longer than the predetermined reference time, the driving of the toilet seat heater is turned off so that the toilet seat heater is not driven unnecessarily for a long time irrespective of whether or not the user is using the toilet.

A method of controlling the drive of a toilet seat heater of a hot water scrubber according to the present invention having such a configuration will be described below. FIG. 3 is a flow chart showing a method for controlling the driving of a toilet seat heater of a hot water scrubber according to the present invention. 3, when the commercial AC power is first applied in step s10, the microprocessor 10 in step s12 applies the driving power obtained by rectifying the commercial AC power by the power supply part 11 And outputs a control signal to the received toilet seat heater driving unit 13 to heat the toilet seat heater. Further, in step (s14), it is detected whether or not the seat occupant is seated in order to determine whether or not the user's hot water washer is used while driving the toilet seat heater. If the seating of the user is detected as a result of the detection in step s14, the time counting unit 12 for counting the time period of the user is initialized in step s14. On the other hand, if it is determined in step s14 that the seating is not detected, the process proceeds to step s16 to increase the time of the time counting unit 12. [

In step s18, the time counted in step s16 is compared with a predetermined reference time. If the counted time is less than or equal to the reference time, the step s12 and subsequent steps are repeated. If it is determined that the user is not using the hot water washer for a predetermined reference time in a situation such as the user going out or at night, The driving of the toilet seat heater is stopped. Therefore, while the user is not using for a long time, the power of the toilet seat heater can be reduced by turning off the driving of the toilet seat heater.

In step s22, when the seating is detected again by the user in the state that the driving of the toilet seat is turned off, the time of the time counting unit 12 is initialized in step s24, and the process proceeds to step s26, And the toilet seat 3 is heated by re-driving.

As described above, according to the apparatus and method for driving a toilet seat heater of a hot water scrubber according to the present invention, a seating period of a user is counted to determine whether or not a user is using the apparatus. When the user is not used for a predetermined period of time, Thereby providing an advantage that waste of power consumption due to unnecessary continuous driving of the toilet seat heater can be prevented.
