In every living space where human beings live, there is a restroom to carry out the basic metabolism of survival. Toilets are mainly used to treat human excreta, and in the past, they were installed in isolated locations away from human residential facilities.

With the modernization of society, the urban population has increased and the residential culture has changed into apartments such as apartments, toilets have been installed in the residential spaces of human beings. Accordingly, the toilet has been developed variously in order to secure sanitary facilities and space inside and to create a pleasant environment.

However, in the toilet, the smell still occurs in the process of disposal, and many pathogens remain. In addition, the internal space of the toilet is not smoothly ventilated. In addition, the user of the toilet may be uncomfortable due to the odor generated when the user sees the toilet.

Therefore, a lot of efforts are being made to create a comfortable and hygienic toilet by effectively disinfecting the pathogens present in the space inside the toilet and eliminating the odor of the toilet.

Reference numeral 180 denotes a steam nozzle. The steam nozzle 180 may be opened when the steam generating module 170 generates steam to discharge the steam in the direction of the spray nozzle 130.

2 is a block diagram showing a configuration of a control apparatus according to an embodiment of the present invention. 2, the control apparatus of the present invention includes a control unit 200, a key input unit 210, a solenoid valve driving unit 220, an instantaneous heating module driving unit 230, a flow valve driving unit 240, A water pump driving unit 250, a steam generating module driving unit 260, a steam nozzle driving unit 270, and a jetting nozzle moving unit 280.

The control unit 200 can control the operation of the bidet and the overall operation of generating sterilization and disinfecting the injection nozzle 130. For example, the control unit 200 may control the washing water to be supplied to the injection nozzle 130 to perform a cleaning operation when a bidet cleaning command is issued. When the steam command is generated, the controller 200 moves the injection nozzle 130 back and forth, and the steam nozzle 180 discharges the steam to the spray nozzle 130 to discharge the spray nozzle 130 Disinfection can be controlled.

The key input unit 210 includes a plurality of function keys. The user can input an operation command of the corresponding function key to the control unit 200 as the user selectively operates the plurality of function keys.

For example, the key input unit 210 includes a plurality of function keys including a bidet key for commanding cleaning and a steam key for commanding the generation of steam. As the user operates the bidet key, the bidet command can be generated and input to the controller 200. [ Also, as the user operates the steam key, a steam command may be generated and input to the controller 200.

The solenoid valve driving unit 220 drives the solenoid valve 100 under the control of the control unit 200 to introduce raw water from the outside.

The instantaneous heating module driving unit 230 applies operating power to the instantaneous heater of the instantaneous heating module 110 under the control of the controller 200 so that the raw water obtained through the solenoid valve 100 The temperature can be instantaneously heated.

The flow valve driving unit 240 is driven under the control of the controller 200 so that the raw water passing through the instantaneous heating module 110 generates washing water or steam for washing an anus or a local part of the user So that the water can be discharged to the steam generating water for the steam.

The water pump driving unit 250 drives the water pump 150 under the control of the control unit 200 so that steam generated water that has passed through the T-type distribution pipe 140 is steamed through the check valve 160 Generating module 170, as shown in FIG.

The steam generating module driving unit 260 generates the steam generating heat of the steam generating module 170 under the control of the controller 200 to generate steam and generate steam.

The steam nozzle driving unit 270 opens the steam nozzle 180 according to the control of the controller 200 so that the steam generated by the steam generating module 170 flows through the steam nozzle 180, In the direction of the arrow.

The injection nozzle moving unit 280 may be driven under the control of the controller 200 to move the injection nozzle 130 back and forth. For example, the injection nozzle moving unit 280 includes a motor (not shown), and the motor is driven in the forward and reverse directions under the control of the controller 200 to drive the injection nozzle 130 It can be moved back and forth.

3 is a signal flow diagram illustrating the operation of an embodiment of the controller according to an embodiment of a flow path formed in a bidet according to the controller of the present invention. Referring to FIG. 3, the controller 200 determines whether an operation command is input from the key input unit 210 (S300).

When an operation command is input from the key input unit 210, the control unit 200 determines whether the input operation command is a bidet command or a steam command (S302).

Here, if steam is generated by operating the steam key inadvertently while the user is using the bidet, the user may be burned by the steam.

Therefore, it is preferable that the steam command is generated when the user presses the steam key for more than a predetermined time, for example, the user continuously presses the steam key for 5 seconds or more. Or when the seat sensor (not shown in the figure) provided on the seat of the bidet does not detect the user, the steam command is generated by depressing the steam key.

If the operation command determined in step S302 is a bidet command, the controller 200 performs a bidet operation, for example, a cleaning operation (S304).

That is, under the control of the control unit 200, the solenoid valve driving unit 220 drives the solenoid valve 100 to introduce the washing water, and the instantaneous heating module driving unit 230 drives the instantaneous heating module 110 The flow valve driving unit 240 drives the flow valve 120 so that the washing water heated by the instantaneous heating module 110 is injected through the flow valve 120 and the injection nozzle 130. [

Here, the cleaning operation of the bidet is the same as the cleaning operation of a general bidet, and a detailed description of the operation will be omitted.

If the operation command determined in step S302 is a steam command, the controller 200 controls the solenoid valve driver 220 to drive the solenoid valve 100 (S306).

When the solenoid valve 100 is driven, external raw water is received and passed through the instantaneous heating module 110.

The control unit 200 controls the flow valve driving unit 240 to drive the flow valve 120 (S308).

As the flow valve 120 is driven, raw water passing through the instantaneous heating module 110 flows out to the T-shaped distribution pipe 140 through the flow valve 120 as steam generating water.

In the present invention, the controller 200 operates the instantaneous heating module 110 to heat the raw water first. However, when the raw water is first heated by operating the instantaneous heating module 110, some of the raw water that has been firstly heated is discharged through the T-type distribution pipe 140, so power consumption may be unnecessarily generated.

In addition, not only the steam generating module 170 can heat the steam generating water to generate sufficient steam, but also the instantaneous heating module 110 is operated to heat the raw water first, and the first heated raw water is supplied to the steam generating module 170, When the steam is generated by the secondary heating, the maximum power consumption becomes very high.

Therefore, in the present invention, it is desirable to stop the instantaneous heating module 110 when steam is generated to prevent unnecessary power consumption and reduce the maximum power consumption.

The steam generating water discharged from the flow valve 120 to the T-type distribution pipe 140 is divided and partially passed through the steam generator, and the remaining steam generated water is discharged.

Here, the T-type distribution pipe 140 is provided in the steam generating module 170 to allow an appropriate amount of steam generated to generate steam to flow.

In this state, the control unit 200 controls the water pump driving unit 250 to drive the water pump 150 (S310).

The steam generated water having passed through the T-type distribution pipe 140 is pumped according to the driving of the water pump 150 and the pumped steam generated water is supplied to the steam generating module 170 through the check valve 160 ≪ / RTI >

Here, the water pump 150 is provided to the steam generating module 170 so that the steam generating water for generating steam can be stably introduced.

In this state, the control unit 200 controls the steam generating module driving unit 260 to drive the steam generating module 170 (S312). That is, the controller 200 heats the steam generated by the steam generating module 170 to heat the generated steam.

Here, as the steam heater is heated to heat the steam generating water, the steam generating water is expanded as well as steam is generated to raise the internal pressure.

When the internal pressure of the steam generating module 170 rises, steam generated in the steam generating module 170 and steam may flow back toward the water pump 150.

Therefore, in the present invention, since the check valve 160 is provided between the water pump 150 and the steam generating module 170, the steam generating water of the steam generating module 170 and the steam generated in the direction of the water pump 150 It is possible to prevent the backflow of the liquid.

The controller 200 determines whether a preset heating time has elapsed (S314). That is, the control unit 200 determines whether a predetermined heating time, which is required for heating the steam heater provided in the steam generating module 170, from the time when the steam generating water is heated to when the steam is generated, .

Here, the heating time may be variable depending on the temperature of the steam generating water, the power capacity of the steam heater provided in the steam generating module 170, the capacity of the steam generating water for generating steam, and the like. For example, 20 to 50 seconds.

When the heating time elapses, steam is generated in the steam generating module 170, and the controller 200 drives the steam nozzle driving unit 270 to apply steam generated from the steam generating module 170 (S316) to drive the injection nozzle moving unit 280 so that the injection nozzle 130 is moved back and forth (S318).

Then, the steam nozzle 180 is discharged to the forward and backward injection nozzles 130 to sterilize the entire injection nozzle 130 with steam.

In this state, the controller 200 determines whether a preset steam output time has elapsed (S320).

That is, according to the present invention, it is determined whether or not a sufficient steam output time, for example, 50 to 80 seconds, sufficient for sterilizing the spray nozzle 130 moving back and forth has been passed through the steam output from the steam nozzle 180 .

When the predetermined steam output time has elapsed, the control unit 200 controls the steam generating module driving unit 260 to stop generating steam from the steam generating module 170 (S322) (280) to stop the forward and backward movement of the injection nozzle (130) (S324).

The control unit 200 continuously drives the solenoid valve 100, the flow valve 120, the water pump 150, and the steam nozzle 180 (S326).

Then, the washing water is received in accordance with the driving of the solenoid valve 100, and the received washing water passes through the instantaneous heating module 110, and then the water is supplied to the T-type distribution pipe 140 Out. The low temperature steam generated in the T-type distribution pipe 140 is sequentially passed through the check valve 160, the steam generating module 170, and the steam nozzle 180 in accordance with the pumping of the water pump 150 The connection pipe connecting the steam generating module 170 to the steam generating module 170 and the steam nozzle 180 and the steam nozzle 180 are cooled by the low temperature steam generated water.

The controller 200 controls the connection between the steam generating module 170 and the steam generating module 170 and the steam nozzle 180 and the connection between the steam generating module 170 and the steam nozzle 180, It is determined whether or not a predetermined cooling time, for example, 30 to 60 seconds, which is required until the cooling water is sufficiently cooled by the steam generating water temperature, elapses (S328).

When the cooling time has elapsed, the control unit 200 stops the cooling operation, for example, stops the solenoid valve 100, the flow valve 120, the water pump 150, and the steam nozzle 180 (S330), and ends all operations related to the generation of steam.

In the present invention, the T-type distribution pipe 140 passes only the amount necessary to generate steam when the amount of steam generated in the flow valve 120 is more than necessary to generate steam, The T-type distribution pipe 140 may not be provided when a necessary amount of steam generating water is discharged from the flow valve 120 to generate steam.

The water pump 150 is for introducing steam generated water stably into the steam generating module 170. When the steam generating water is stably discharged from the flow valve 120, It may not.

4 is a view showing a configuration of another embodiment of a flow path formed in a bidet according to the control apparatus of the present invention. Referring to FIG. 4, another embodiment of the flow path of the present invention includes a switching valve 400 between the instantaneous heating module 110 and the flow valve 120.

The switching valve 400 allows the raw water to flow out from the instantaneous heating module 110 to the washing water to flow into the flow valve 120, or the raw water to the steam generating water.

A T-type distribution pipe 410 is provided between the switching valve 400 and the water pump 150.

The T-type distribution pipe 410 allows a part of the steam generated water from the switching valve 400 to flow into the water pump 150, and the remaining steam generated water is discharged to the outside.

5 is a block diagram showing the configuration of a control apparatus according to another embodiment of the flow path of the present invention. Referring to FIG. 5, the control apparatus of the present invention may further include a switch valve driver 500.

The switching valve driving unit 500 drives the switching valve 400 under the control of the controller 200 to selectively supply the raw water flowing from the instantaneous heating module 110 to the washing water or steam generating water can do.

6 is a signal flow diagram illustrating the operation of the controller according to another embodiment of the flow path of the present invention. Referring to FIG. 6, the controller 200 determines whether an operation command is input from the key input unit 210 (S600).

When an operation command is input from the key input unit 210, the controller 200 determines whether the input operation command is a bidet command or a steam command (S602).

If the operation command determined in step S602 is a bidet command, the controller 200 performs a bidet operation, for example, a cleaning operation (S604).

That is, the control unit 200 controls the solenoid valve driving unit 220 to drive the solenoid valve 100 to flow the external raw water, and the instantaneous heating module driving unit 230 drives the instantaneous heating module 110 , And controls the raw water flowing through the solenoid valve (100) to be heated to a temperature required by the user. The control unit 200 controls the switching valve driving unit 500 to drive the switching valve 400 so that the raw water heated to the temperature required by the instantaneous heating module 110 is discharged to the washing water, The cleansing water is sprayed through the spray nozzle 130 to clean the anus or the local part of the user.

When the operation command determined in step S602 is a steam command, the controller 200 controls the solenoid valve driver 220 to drive the solenoid valve 100 (S606) Controls the switching valve 400 to output the steam generation number (S608).

Then, the raw water flows into the steam generating water through the switching valve 400 after passing through the instantaneous heating module 110. The switching valve 400 is connected to the switching valve 400, A part of the steam generated water coming out from the steam generator 400 flows into the water pump 150 through the T-type distribution pipe 410, and the remaining steam generated water is discharged.

At this time, the controller 200 does not drive the instantaneous heating module 110, so that the raw water introduced from the outside is not heated, so that the steam generating water having a low temperature is discharged from the switching valve 400.

The control unit 200 controls the water pump driving unit 250 to drive the water pump 150 at step S610 and controls the steam generating module driving unit 260 to drive the steam generating module 170 at step S612, .

Then, the steam generated water having passed through the T-shaped distribution pipe 410 is pumped in accordance with the driving of the water pump 150 and flows into the instantaneous heating module 170 through the check valve 160, (170) heats the steam generated water to generate steam.

In this state, the controller 200 determines whether a preset heating time has elapsed (S614).

When the heating time elapses, steam is generated in the steam generating module 170 and the control unit 200 drives the steam nozzle driving unit 270 so that the steam generated in the steam generating module 170 is steamed (S616). Then, the injection nozzle moving unit 280 is driven to move the injection nozzle 130 back and forth (S618).

Then, the steam nozzle 180 is discharged to the forward and backward injection nozzles 130 to sterilize the entire injection nozzle 130 with steam.

In this state, the controller 200 determines whether a predetermined steam output time has elapsed (S620).

When the predetermined steam output time has elapsed, the control unit 200 controls the steam generating module driving unit 260 to stop generating steam from the steam generating module 170 at step S622, (280) to stop the forward and backward movement of the injection nozzle (130) (S624).

The control unit 200 continuously drives the solenoid valve 100, the switching valve 400, the water pump 150, and the steam nozzle 180 (S626).

Then, the raw water is received according to the driving of the solenoid valve 100, and the raw water that has been obtained passes through the instantaneous heating module 110 and then exits the steam generating water from the switching valve 400 to be supplied to the T-type distribution pipe 140, And the low temperature steam generating water that has passed through the T-type distribution pipe 140 passes through the check valve 160, the steam generating module 170, and the steam nozzle 180 A connection pipe for connecting between the steam generating module 170 and the steam generating module 170 and the steam nozzle 180 by means of low temperature steam generating water, Is cooled.
