The present invention relates to a bidet capable of generating electricity through power generation, and more particularly, to a self-powered bidet that performs power generation using water supplied to a toilet or bidet.

In general, a bidet is a device for cleaning the anus and / or female part of the human body and is also called a hot water washing device or a local washing device.

The bidet includes a mechanical bidet that sprays water by directly operating a lever, and various operations provided to the bidet by pressing a button of a specific function, for example, a bidet function, a cleaning function, a nozzle cleaning function, and a drying function. There is an electronic bidet that does this automatically.

However, the mechanical bidet does not have a separate external power source, so the user has to adjust all the operations, and the electronic bidet can be operated only when an external power source is connected. Not available in.

In order to solve the difficulty of connecting the electric bidet of the electronic bidet, it is possible to consider a method of using various functions of the bidet by using a battery, but it is inconvenient to replace the battery from time to time.

In order to solve this problem, a method of generating electricity by using water pressure of raw water supplied from a tap water and the like has been proposed. The power generation bidet is to install the generator in the pipe connected to the water storage tank for flushing the toilet, but it will be a lot of trouble and difficulty to install the generator in the pipe. In addition, since the charging unit for storing the electricity generated by the generator is located inside the bidet body, the wiring electrically connecting the generator and the charging unit is exposed to the outside of the bidet body. In such a case, there are various problems such as not only harming the aesthetics but also the user's carelessness or mischief due to the user's intentional disconnection or the user's tripping over.

Let's look at it.

First, a self-powered bidet 100 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3.

As shown in FIG. 1, the self-powered bidet 100 according to an embodiment of the present invention generates power by the raw water inlet 110 and the raw water introduced into the raw water inlet 110. The generator 120 to perform, the charging unit 130 for storing the electricity generated by the generator 120, the nozzle unit 150 configured to spray the raw water introduced into the raw water inlet 110 to the human body and And a nozzle flow path part 140 provided between the generator 120 and the nozzle part 150 to supply raw water that has passed through the generator 120 to the nozzle part 150. It may further include a control unit (C) for controlling the opening and closing of the flow path nozzle 140 to drive. In addition, the self-powered bidet 100 according to an embodiment of the present invention as shown in Figure 2 is the generator 120 to supply the raw water passed through the generator 120 to the storage tank 230 for toilet bowl cleaning. And may include a tank flow path section 190 provided between the reservoir tank 230. And, as shown in Figure 3, the self-powered bidet 100 according to an embodiment of the present invention is to supply the raw water passed through the generator 120 to the bowl 240 of the toilet bowl and the generator 120 and the bowl ( It may also include a flushing flow path portion 190 ′ provided between the 240.

The self-powered bidet 100 shown in FIG. 2 further includes a tank flow path section 190 installed to supply raw water that has passed through the generator 120 to the water storage tank 230, and is shown in FIG. 3. Self-powered bidet 100 is a self-powered bidet shown in FIG. 1 only in that it further includes a flushing flow path portion 190 ′ installed to supply raw water passing through the generator 120 to the bowl 240 of the toilet seat. Since there is a difference from the 100, the self-powered bidet 100 shown in Figs. 1 to 3 will be described together.

The raw water inlet 110 receives raw water from a raw water supply unit 210 installed outside the bidet housing 180, such as a water pipe or a pipe connected thereto, and has a connection port for connection to the water pipe.

The raw water introduced into the raw water inlet 110 is introduced into the generator 120 to generate power. Generator 120 used in the present invention is provided with an impeller (aberration) is the rotation of the impeller occurs when the raw water flows into the generator 120 is to perform power generation through this. In addition, the charging unit 130 is electrically connected to the generator 120 to store electricity in the generator 120, the electricity charged in the charging unit 130 is the use of the bidet, that is, nozzle drive unit 160 or various Used to drive the valves 143, 144, 147. As such, the configuration of the generator 120 for generating power by the flow of the fluid and the charging unit 130 for charging the electricity generated through the fluid is known in various forms, so a detailed description thereof will be omitted.

On the other hand, the raw water passed through the generator 120 is supplied to the nozzle unit 150 through the nozzle passage 140. In this case, the nozzle passage 140 may be provided with a variety of valve devices (143, 144, 147) to supply or block the raw water to the nozzle unit 150, the specific configuration is limited to the example shown in Figs. It doesn't work.

In addition, the nozzle unit 150 may be made of only the injection nozzle 151 for cleaning the anus and / or the female part of the human body, the injection to clean the outer surface (particularly, the upper surface) of the injection nozzle 151 It may be configured to include a washing nozzle 152 for spraying raw water to the upper surface side of the nozzle 151.

At this time, as shown in Figures 1 and 2, the nozzle passage 140 is for supplying the raw water to the injection nozzle passage 146 and the washing nozzle 152 for supplying the raw water to the injection nozzle (151). The cleaning nozzle passage 148 may be provided. The injection nozzle flow path 146 is provided with a first on-off valve 143 for opening and closing the injection nozzle flow path 146, the flow control valve to adjust the flow rate of the raw water passing through the first on-off valve 143 144 may be installed. In addition, a second opening / closing valve 147 may be installed in the washing nozzle passage 148 to open and close the washing nozzle passage 148.

At this time, the first on-off valve 143 and the second on-off valve 147 is preferably configured as a latch valve on / off (ON / OFF) by an electrical signal in order to minimize power consumption. Since the configuration of the latch valve is known in various forms and structures, a detailed description thereof will be omitted.

In addition, the flow control valve 144 may also be configured as a latch valve capable of adjusting the flow rate by being turned on / off by an electrical signal. As shown in FIGS. 1 and 2, the flow regulating valve 144 has a body having one inflow path into which raw water is introduced and a plurality of outlet paths 145a and 145b selectively opened to allow flow rate control. 144a and a water inlet 144b into which the plurality of water outlets 145a and 145b are combined.

Specifically, as shown in FIG. 6 as an example, the flow control valve 144 is connected to the nozzle flow path 141 and the inflow path 310 through which the raw water passed through the generator 120 is always opened. And a latch valve including a first flow path 145a capable of discharging raw water and a second flow path 145b opened by application of power.

The flow control valve 144 has a coil wound around a solenoid SL located inside the upper housing 327, and a plunger 322 and an iron core 329 are disposed inside the solenoid SL, and an iron core ( The permanent magnet M is disposed at the upper portion of the 329, and the spring 325 is disposed at the lower portion of the iron core 329 to push the plunger 322 toward the water outlet 314.

The lower housing 328 is connected to the nozzle flow path 141 to form an inflow path 310 through which the raw water passed through the generator 120 flows in and a second flow path 145b through which the raw water passed through the space 330 is discharged. It is. Plastic having a rubber diaphragm 320 and the diaphragm 320, the inlet 311 and the outlet 314 is formed at the end of the inflow path 310 and the second flow path (145b). The support 321 of the material is provided. In addition, the inflow passage 310 communicates with the space portion 330 through the inlet 311, and the second flow path 145b communicates with the space portion 330 through the outlet 314.

In addition, a first flow path 145a is formed in the diaphragm 320 and the space 330 between the support 321 and the upper housing 327, and a spring as the stopper 332 is formed on the upper surface of the support 321. It is installed. The stopper 332 has a radius larger than the radius of the plunger 322 so that when the support 321 rises together with the diaphragm 320, the stopper 332 preferentially meets the housing 327 of the upper portion, so that the support 321 and the diaphragm have a radius. The rising position of the 320 is limited.

As shown in FIG. 6, the flow regulating valve 144 according to the exemplary embodiment has an inflow path through the space part 330 even when the plunger 322 is in an OFF position blocking the outlet 314. Since the 310 and the first flow path 145a communicate with each other, raw water may be discharged through the first flow path 145a when the first open / close valve 143 is opened. In addition, when the flow control valve 144 is turned on (ON), the plunger 322 is raised to the outlet 314 is open, so that the raw water flowing through the inlet 311 is passed through the outlet (314) second flow path ( 145b) also flows out. Therefore, the raw water discharged from the first flow path 145a and the second flow path 145b is discharged through the water discharge port 144b of FIGS. 1 and 2 and then supplied to the injection nozzle 151. Therefore, when the flow rate control valve 144 is in the ON state, more flow rates may flow by the flow rate through the second flow path 145b than in the OFF state.

In this way, when the latch valve as the first on-off valve 143 and the latch valve as the flow control valve 144 are used, when the low pressure (low flow rate) injection is required in the injection nozzle 151, the first on / off valve 143 is used. If only a high water pressure (high flow rate) injection is required, only the flow rate control valve 144 is opened in the state where the first on-off valve 143 is opened. Water pressure can be achieved and the power consumption can be maximized.

On the other hand, the nozzle passage 140 is a manual valve for forcibly blocking the flow in the case of adjusting the opening and closing amount of the valve to adjust the inflow of raw water, or when an abnormality occurs in the components constituting the flow path, or need to replace parts 142 may be installed, and this manual valve 142 is normally kept open.

In addition, the injection nozzle 151 may be provided with a bidet nozzle and a cleaning nozzle, that is, two nozzles that perform respective functions to perform a bidet function and a cleaning function, but is not limited thereto. It is possible.

In addition, the nozzle unit 150 may include a nozzle driving unit 160 for moving the injection nozzle 151 in the front-rear direction. In this case, the nozzle driving unit 160 may achieve a reduction in power consumption compared to the case of using a stepping motor by using a DC motor.

Specifically, the efficiency of DC motor is 75% ~ 80%, but the stepping motor has to use current with multiple phases for precise position control, so current usage efficiency is 50 ~ 60%, which is 25 ~ 30% lower than the above DC motor. Level. Therefore, when using a DC motor as an embodiment of the present invention has an excellent effect in terms of power consumption compared to the case of using a stepping motor is suitable for a self-powered bidet. As the DC motor, a brush DC motor or a brushless DC motor may be used.

In addition, the movement of the injection nozzle 151 by the driving of the nozzle driver 160 may be controlled by using a variable resistor associated with a DC motor. Since a technique for controlling the amount of rotation of the DC motor by the variable resistor is well known, a detailed description thereof will be omitted.

In addition, when only one injection nozzle 151 is provided in the nozzle unit 150, cleaning is performed through one injection nozzle 151 by controlling the driving of the nozzle driver 160 so that the moving distance of the injection nozzle 151 is different. Functions and bidet functions can be implemented. As such, when only one injection nozzle 151 is provided, the nozzle unit 150 is simpler in configuration than the two injection nozzles 151 and only one injection nozzle 151 is moved. There is an advantage that control of 160 is easy. That is, when two injection nozzles 151 are provided, a complicated gear structure is required to move only one injection nozzle 151 as one nozzle driving unit (motor) 160, but one injection nozzle 151 is required. If only) is used, the structure for driving the injection nozzle 151 is simple, which facilitates the control of the nozzle driver 160. In addition, as described above, when the DC motor is used as the nozzle driving unit 160 and the moving distance of the injection nozzle 151 (that is, the amount of rotation of the DC motor) is controlled by a variable resistor, a stepping motor is used. Reduction of power consumption can be achieved.

Meanwhile, the tank flow path part 190 illustrated in FIG. 2 is branched from the nozzle flow path part 140 downstream of the generator 120 so as to supply raw water having passed through the generator 120 to the storage tank 230 for toilet bowl cleaning. It is configured to be connected to the storage tank 230. For example, the tank flow passage part 190 may include a connection port 192 to connect the tank flow passage 191 and the storage tank 230 branched from the nozzle flow passage 141. As such, by installing the tank flow path unit 190 downstream of the generator 120 to clean the toilet bowl using the water contained in the water storage tank 230, when the water is supplied again to the water storage tank 230, the raw water generator ( 120), through which the development is made.

3, the nozzle flow path downstream of the generator 120 is configured to supply raw water that has passed through the generator 120 to the bowl 240 of the toilet in which the washing water for washing the toilet is accumulated. Branched from the unit 140 is configured to be connected to the bowl 240. For example, the flushing flow path part 190 ′ may include a connection port 192 ′ such that the flushing flow path 191 ′ branched from the nozzle flow path 141 and the bowl 240 may be connected to each other. As such, by installing the flushing flow path part 190 ′ downstream of the generator 120, when the user flushes water before or after using the toilet, the raw water is supplied to the generator 240 when water is supplied to the bowl 240. It will pass through, and development will take place.

As such, since the self-powered bidet 100 shown in FIG. 1 performs power generation of the generator 120 while discharging raw water through the nozzle unit 150, the self-powered bidet 100 may be installed in the toilet seat having no water storage tank 230. You can get it. In particular, when the bidet is used to perform power generation using raw water discharged through the spray nozzle 152 or raw water sprayed through the spray nozzle 151, the power generation capacity is not sufficient or the voltage of the charging unit 130 In such a low case, a large amount of raw water is discharged through the nozzle unit 150 for a sufficient time (for example, 1 liter or less per minute of raw water is discharged for 1 to 2 minutes), thereby enabling generation of sufficient capacity.

In addition, the self-powered bidet 100 shown in FIG. 2 uses a raw water discharged through the washing nozzle 152 for washing raw water or nozzles sprayed through the spray nozzle 151 when the bidet is used, as well as a water storage tank. Since power generation using raw water supplied to 230 is performed, power generation of sufficient capacity is possible. In addition, when the voltage of the charging unit 130 is low, since power generation is performed through a large amount of raw water forcibly discharged through the nozzle unit 150, power generation is possible in various ways, and the effect of replenishing insufficient electricity is obtained. Can be.

And, the self-powered bidet 100 shown in FIG. 3 uses the raw water discharged through the washing nozzle 152 for washing raw water or nozzles sprayed through the spray nozzle 151 when using the bidet, as well as a bowl ( Since power generation using raw water supplied to 240 is performed, power generation of sufficient capacity is possible. In addition, when the voltage of the charging unit 130 is low, since power generation is performed through a large amount of raw water forcibly discharged through the nozzle unit 150, power generation is possible in various ways, and the effect of replenishing insufficient electricity is obtained. Can be.

As such, the self-powered bidet 100 according to the embodiment of the present invention does not simply generate power through the raw water supplied to the storage tank 230 or the bowl 240 of the toilet bowl, but to the nozzle unit 150 when the bidet is used. When supplying raw water or power generation is required, power generation through the raw water discharged to the nozzle unit 150 is forcibly performed, thereby increasing power generation capacity and maintaining sufficient charging unit voltage at all times.

On the other hand, the control unit (C) is a variety of valves (143, 144, 147) installed in the nozzle flow path unit 140 so that the raw water is discharged through the nozzle unit 150 when the voltage of the charging unit 130 is lower than the predetermined charging required voltage ) By controlling the opening and closing of the generator 120 may be driven. This charging required voltage may be set to an appropriate value in consideration of the power required to use the function of the bidet.

That is, when the user fails to secure a power of sufficient capacity to use the bidet function and / or cleaning function after the toilet, the charging unit 130 needs to be charged. For this purpose, the controller C is charged to the charging unit 130. It is determined whether the voltage of the charging unit 130 is higher than the predetermined charging required voltage, and if the voltage of the charging unit 130 is lower than the charging required voltage, power generation is performed through the nozzle unit 150. In detail, the controller C opens the flow path of the nozzle flow path part 140 so that raw water is discharged from the nozzle part 150 to the bowl of the toilet to generate power in the generator 120. That is, since the generator 120 generates power only when the fluid flows therein, in the case of the present invention, if the voltage of the charging unit 130 is not sufficient, the nozzle passage unit 140 is automatically opened for the generation of the generator 120. The raw water flows from the nozzle unit 150 to the bowl of the toilet bowl.

As described above, the nozzle unit 150 may include a spray nozzle 151 for cleaning the anal part of the human body and / or a female part, and the control unit C may have the spray nozzle 151 extended toward the human body. Raw water is controlled by controlling the opening and closing of the first opening / closing valve 143 provided in the nozzle driving unit 160 and the nozzle flow path unit 140 so that the spraying is performed in a non-exposed state, that is, not exposed to the outside of the bidet housing 180. It is possible to prevent the injection directly into the human body. In addition, even if the injection nozzle 151 is not exposed to the outside of the bidet housing 180, the upper side of the injection nozzle 151 to prevent the splashing of raw water to the human body or to prevent the raw water penetrates into the bidet housing 180. It is also possible to attach a separate cover to the.

In addition, when the nozzle unit 150 includes not only the spray nozzle 151 but also the washing nozzle 152, since the spraying direction of the raw water in the washing nozzle 152 is downward, the raw water is supplied through the washing nozzle 152. It is desirable to discharge and thereby generate electricity. In this case, the control unit C may open the second on / off valve 147 to allow the raw water to flow through the washing nozzle flow path 148 to generate power of the generator 120.

That is, when spraying the raw water through the washing nozzle 152, water splashing to the user can be minimized than when discharging the raw water through the spray nozzle 151, which can be generated while minimizing user inconvenience. There is an advantage. In addition, when the raw water is discharged through the washing nozzle 152, since water splash is minimized, it is possible to increase the raw water discharge flow rate and to additionally wash the spray nozzle 151.

On the other hand, unlike the above, the control unit (C) opens and closes the various valves (143, 144, 147) installed in the nozzle flow path unit 140 so that the raw water is discharged through the nozzle unit 150 when a preset condition is met. It is also possible to control the generator 120 to be driven. For example, as described below, the control unit C uses the seating sensor S to detect the user's seating time more than a predetermined number of times, or the number of times that the user uses the bidet function or the washing function is a certain number of times. The generator 120 may be generated by detecting the number of times of using the bidet, and when the user does not use the bidet for a long time, the generator 120 may not be discharged when a certain period of time has elapsed. It is also possible to allow development to be carried out.

On the other hand, the self-powered bidet 100 according to an aspect of the present invention may include a seating sensor (S) for generating a seating signal by detecting that the user seated on the toilet seat. Such a seating sensor may be a sensor for measuring an electrical change according to a user's seat, such as a capacitive sensor, an infrared sensor for detecting a user's approach may be used, such as a micro switch, when the user is seated on a seat If the user's seat can be detected, such as a contact switch in which switching is performed, the type, detection method, and installation location are not particularly limited.

As such, when the seating sensor S is provided, the control unit C is configured to supply power from the charging unit 130 when a seating is detected by the seating sensor S, and from the seating sensor S. When the user's departure is detected, the power supply from the charging unit 130 is cut off after a preset waiting time, thereby minimizing power consumption when the user does not use the bidet. That is, when a certain time elapses after the user leaves the toilet seat, power is supplied from the charging unit 130 to various electric components, for example, various valves 143, 144, and 147, the nozzle driving unit 160, and a display (not shown). By doing so, power consumption can be minimized.

In this case, it is preferable that the power supply from the charging unit 130 is made when the user's seat is detected by the seating sensor S so that the bidet is automatically available when the user sits. At this time, the seating sensor (S) for detecting the user's seating preferably includes a contact switch that the user is pressed when seated on the toilet seat is mechanically switched. That is, in a conventional bidet, a capacitive sensor or an infrared sensor may be used as the seating sensor S, but after the user leaves the toilet seat, the power is forcibly cut off from the charging unit 130 and when the user sits down for reuse. It is preferable that a contact sensor such as a micro switch is used so that switching is performed by a load or pressure of a user so as to be detected mechanically.

On the other hand, in order to maximize power generation in the generator 120, the raw water supplied to the storage tank 230 should minimize the occurrence of pressure or flow rate loss, but the raw water pressure of the raw water supply unit 210 is the same as that of the nozzle flow path unit 140 When applied to a component, component failure or shortened life may occur.

Therefore, while maintaining the pressure of the raw water supplied to the tank flow path unit 190 in a high state, the tank flow path provided in the tank flow path unit 190 to relatively reduce the pressure of the raw water supplied to the nozzle flow path unit 140. The diameter of the 191 is preferably larger than the diameter of the nozzle passage 141 provided in the nozzle passage 140.

At this time, the ratio of the diameter of the nozzle passage 141 and the diameter of the tank passage 191 is preferably made of 1: 1.2 to 5. If the diameter of the tank flow path 191 is smaller than 1.2 times the diameter of the nozzle flow path 141, since the raw water pressure flowing into the nozzle flow path 141 is high, the damage or lifespan of the components installed in the nozzle flow path part 140 may be reduced. On the contrary, if it exceeds 5 times, the diameter of the nozzle passage 141 is too small compared to the diameter of the tank passage 191, so that the injection of the injection nozzle 151 cannot be properly implemented in the bidet use process and the nozzle portion ( 150, since the flow rate of the raw water discharged during the power generation process performed while discharging the raw water is small, sufficient power generation cannot be achieved.

For the same reason as described above in the tank flow path unit 190, the pressure of the raw water supplied to the flushing flow path unit 190 ′ is maintained at a high state while the pressure of the raw water supplied to the nozzle flow path unit 140 is relatively reduced. In order to achieve this, the diameter of the water flow passage 191 ′ provided in the water flow passage portion 190 ′ is larger than the diameter of the nozzle flow passage 141 provided in the nozzle flow passage portion 140.

On the other hand, the self-powered bidet 100 according to an aspect of the present invention, as shown in FIG. 1, the generator 120, the charging unit 130, the nozzle unit 150, and the nozzle flow path unit 140 are arranged in the bidet housing 180. ) As it is installed integrally inside, the pipes or components for power generation are not exposed to the outside, so the aesthetics are excellent, and the configuration for power generation is completed only by connecting the raw water supply unit 210 and the raw water inlet unit 110. The effect of installing the bidet is extremely easy. In addition, when the tank flow path unit 190 is provided, as shown in FIG. 2, by installing the inside of the bidet housing 180 up to the configuration of the tank flow path unit 190, the effect of improving aesthetics and ease of installation can be achieved. Will be. In addition, as shown in FIG. 3, when the flushing flow path part 190 ′ is provided, the configuration of the flushing flow path part 190 ′ is installed inside the bidet housing 180 to improve aesthetics and ease of installation work. Can be achieved.

On the other hand, when high-pressure raw water directly flows into the generator 120, a considerable noise is generated due to the rapid rotation of the impeller, so that the noise generated by the self-power generation is minimized in the high-pressure region, but the power generation nozzle can be secured. In order to prevent the damage of the components installed in the unit 140 from occurring, it is necessary to properly reduce the raw water pressure. For this purpose, it is preferable to install a pressure reducing valve 115 for reducing the raw water pressure to a predetermined level or less between the raw water inlet 110 and the generator 120.

Next, referring to FIGS. 4 and 5, a self-powered bidet according to another embodiment of the present invention will be described.

4 and 5, the self-powered bidet 100 illustrated in FIGS. 1 to 3 is introduced into the raw water inlet 110 through which raw water is introduced, and the raw water inlet 110. Generator 120 for generating power by the raw water, a charging unit 130 for storing the electricity generated by the generator 120, and a nozzle configured to spray the raw water introduced into the raw water inlet 110; And a nozzle flow path unit 140 provided between the generator 150 and the nozzle unit 150 to supply raw water having passed through the generator 150 to the nozzle unit 150. And a tank flow path unit 190 provided between the generator 120 and the storage tank 230 to supply raw water having passed through the generator 120 to the storage tank 230 for toilet bowl cleaning, and the charging unit 130. When the voltage of the lower than the charging voltage required to discharge the raw water through the nozzle unit 150 By opening the passage of the nozzle passage part 140 is the power generator 120 may further include a control unit (C) to be driven. In addition, although not separately illustrated, as illustrated in FIG. 3, instead of the tank flow path unit 190, the generator 120 and the bowl () may be supplied to supply raw water that has passed through the generator 120 to the bowl 240 of the toilet seat. When the voltage of the water flow passage portion 190 ′ provided between the 240 and the charging unit 130 is lower than the voltage required for charging, the nozzle passage portion 140 of the nozzle passage portion 140 discharges raw water through the nozzle unit 150. It may further include a control unit (C) for opening the flow path to drive the generator 120.

4 and 5, the self-powered bidet 100 illustrated in FIGS. 4 and 5 is introduced from the hot water inlet 170 through which hot water is introduced, the raw water from the raw water inlet 110, and the hot water inlet 170. The mixing valve 141a provided downstream of the generator 120 is mixed to mix the hot water, and thus, the raw water having passed through the mixing valve 141a is supplied to the nozzle unit 150. In order to avoid unnecessary duplication, detailed descriptions of the same or similar parts will be omitted, and only the hot water inlet 170, the mixing valve 141a, and the related configuration will be described.

As shown in Figure 4 and 5, the hot water inlet 170 is connected to the hot water supply unit 220, such as boiler piping that can generate or supply hot water is connected to the connection port to supply hot water to the nozzle flow path unit 140 It is configured to. At this time, the hot water flow path 171 is joined to the nozzle flow path 141 downstream of the generator 120, thereby preventing the phenomenon in which the magnet of the generator 120 is damaged by the hot water introduced into the hot water inlet 170. You can do it.

In addition, the hot water passing through the hot water flow path 171 is introduced into the mixing valve 141a to be mixed with the raw water introduced from the raw water inlet 110. At this time, the mixing valve 141a may be configured to manually or automatically adjust the mixing degree of hot water and raw water (cold water) in order to control the temperature of the water sprayed through the injection nozzle 151.

As such, when the hot water inlet 170 is provided, the temperature of the water sprayed through the injection nozzle 151 may be adjusted, and in particular, the mixing valve 141a is installed downstream of the generator 120 to generate a generator by hot water. By preventing the phenomenon that the magnet of the 120 is damaged can be obtained that the smooth use of the generator 120 is possible.

On the other hand, if the self-power generation in the high water pressure (for example, more than 5kgf hydraulic pressure) region can be generated large enough, but when the raw water of high pressure directly flows into the generator 120, due to the rapid rotation of the impeller There is a problem that noise is generated. Therefore, it is necessary to properly reduce the pressure of the raw water so as to minimize the noise caused by the self-power generation in the high water pressure area to secure the power generation capacity. To this end, it is preferable to install a pressure reducing valve 115 for reducing the raw water pressure to a predetermined level (for example, 3 to 4 kgf) or less between the raw water inlet 110 and the generator 120 as shown in FIG. 4. Do.

On the other hand, in the low water pressure region, since the noise of the generator 120 due to the original water pressure is not high, it is possible to install a pressure reducing valve, but the components installed in the nozzle flow path part 140 due to the water pressure fluctuation (water hammer phenomenon) Since damage may occur, it is possible to install the pressure reducing valve 115 in the nozzle flow path part 140 downstream of the generator 120 as shown in FIG. 5. On the other hand, as shown in Figure 5 it is also possible to install a check valve 111 in the raw water inlet 110 so that the raw water introduced into the raw water inlet 110 does not flow back.

Next, the control method applicable to the self-powered bidet 100 according to an embodiment of the present invention with reference to the configuration of the self-powered bidet 100 shown in FIGS. 1 to 5 and the flowcharts of FIGS. 7 and 8 ( Look at S100).

First, the control method (S100) of the self-powered bidet according to an embodiment of the present invention, the generator 120, the charging unit 130, the nozzle unit 150 and the nozzle passage 140 as shown in FIG. Raw water flowing through the nozzle flow path unit 140 (hereinafter, simply referred to as 'raw water', including a state in which raw water and hot water are mixed, as shown in FIGS. 4 and 5 in the description of the control method). Self-powered bidet 100 through which power generation of the generator 120 is performed, or as shown in FIGS. 2, 4, and 5, the generator 120, the charging unit 130, the nozzle unit 150, and the nozzle flow path unit ( Self-powered bidet 100 in which power generation of the generator 120 is performed through the raw water flowing through the tank flow path 190 and the nozzle flow path 140, including the 140 and the tank flow path 190, or FIG. 3. As shown in the drawing, the generator 120, the charging unit 130, the nozzle unit 150, the nozzle passage unit 140, and the water flow passage unit 190 ′ include water. It relates to a control method of the self-powered bidet 100 is the power generation of the generator 120 through the raw water flowing down the flow passage (190 ') and the nozzle flow path (140).

As shown in Figure 7, the control method (S100) of the self-powered bidet according to an embodiment of the present invention is a seating detection step (S110) for detecting that the user is seated on the toilet seat (not shown) and the charging unit voltage If the voltage is lower than the required voltage includes a voltage check step (S130) for generating power through the generator 120, and after the voltage check step (S130), supply raw water to the nozzle unit 150 according to the user's function selection It may include a bidet using step (S150) to spray.

The seat detection step (S110) detects whether the user is seated on the toilet seat through the seat sensor (S). Such a seating sensor may be a sensor for measuring an electrical change according to a user's seat, such as a capacitive sensor, an infrared sensor for detecting a user's approach may be used, such as a micro switch, when the user is seated on a seat If the user's seat can be detected, such as a contact switch in which switching is performed, the type, detection method, and installation location are not particularly limited.

As such, when the user's seating detection is performed, the voltage charged in the charging unit 130 is checked and if the charging unit voltage is not sufficient, that is, the user secures a power of sufficient capacity to use the bidet function and / or cleaning function after the toilet. If not, the voltage checking step S130 of charging the charging unit 130 is performed.

Specifically, the voltage checking step (S130) determines whether the current charging unit voltage charged in the charging unit 130 is lower than a predetermined charging required voltage when the user's seat is detected, and if the charging unit voltage is lower than the charging required voltage. The charging unit 130 is charged by performing power generation through the generator 120.

As shown in FIG. 8, the voltage checking step S130 includes a voltage measuring step S131 of measuring a charging unit voltage charged in the charging unit 130 and determining whether the charging unit voltage is higher than a predetermined charging required voltage. It may be configured to include a charge determination step (S132), and a power generation step (S133) for generating power when the charging unit voltage is lower than the charging required voltage.

At this time, the power generation step (S133) is to generate power by opening the flow path of the nozzle flow path unit 140 so that raw water is discharged from the nozzle unit 150 to the bowl of the toilet. That is, since the generator 120 generates power only when the fluid flows therein, in the case of the present invention, when the charging part voltage is not sufficient, the generator 120 automatically opens the nozzle flow path part 140 for power generation of the generator 120. From 150, the enemy will flow into the bowl of the toilet.

The nozzle unit 150 may include an injection nozzle 151 for cleaning the anus and / or female part of the human body, and in the power generation step S133, the injection nozzle 151 is not extended toward the human body. That is, since the injection is made in a state that is not exposed to the outside of the bidet housing 180, it is possible to prevent the raw water is directly sprayed on the human body. In addition, even if the injection nozzle 151 is not exposed to the outside of the bidet housing 180, the upper side of the injection nozzle 151 to prevent the splashing of raw water to the human body or to prevent the raw water penetrates into the bidet housing 180. It is also possible to attach a separate cover to the.

Unlike the above, the nozzle unit 150 is a jet nozzle 151 for cleaning the anus and / or female part of the human body and the injection nozzle to clean the outer surface (particularly, the upper surface) of the jet nozzle 151 It may be configured to include a washing nozzle 152 for spraying the raw water to the upper surface side of the (151). As such, when the washing nozzle 152 is provided, since the spraying direction of the raw water is downward in the washing nozzle 152, it is preferable to discharge the raw water through the washing nozzle 152 and to generate electricity through the washing nozzle 152. That is, when spraying the raw water through the washing nozzle 152, water splashing to the user can be minimized than when discharging the raw water through the spray nozzle 151, which can be generated while minimizing user inconvenience. There is an advantage. In addition, when the raw water is discharged through the washing nozzle 152, since water splash is minimized, it is possible to increase the raw water discharge flow rate and to additionally wash the spray nozzle 151.

The power generation step S133 is continued until the charging unit voltage is greater than or equal to the charging required voltage (S134).

On the other hand, the voltage check step (S130) is a charging unit voltage is charged immediately without ending the power generation step (S133) when the charging unit voltage being charged is not lower than the charging required voltage, that is, higher than or equal to the charging required voltage Further power generation may be performed for a predetermined time so as to be higher than the required voltage.

That is, the voltage check step (S130), after the power generation step (S133) during the predetermined power generation holding time further discharge the raw water to the nozzle unit 150 to perform a further power generation step (S135) It may include. By performing the additional power generation step (S135) as described above, even if the user uses the bidet function or the washing function a plurality of times, the stable nozzle unit 150 can be operated. In particular, by setting the charging unit voltage to a certain level higher than the required voltage through the additional power generation, it is possible to prevent the power generation is not performed every time the user sits on the toilet seat, thereby minimizing the inconvenience that the user feels. The power generation holding time may vary depending on the raw water pressure or the generator performance, but for example, the power generation may not be performed every time the user uses the toilet seat, and may be set such that the power generation may be performed after multiple uses.

In addition, in the case of the additional power generation step (S135), as in the power generation step (S133) described above may be performed by spraying the raw water to the injection nozzle 151, in the case of having a washing nozzle 152 of the water splash phenomenon More preferably, power generation is performed by discharging raw water to the washing nozzle 152 in consideration of minimization, maximizing raw water discharge flow rate, washing of the injection nozzle 151, and the like.

Then, as shown in Figure 8, after the voltage check step (S130) of the charging unit 130 is finished, the user goes through the standby step (S145) until the user's function selection, and after the user's function selection bidet The use step S150 is performed.

In the bidet use step (S150), as in the normal bidet, the wash performing step (S151 to S154) to perform the cleaning function for cleaning the anus of the human body by the user's selection and / or bidet function for washing the local part of women It may include a bidet performing step (S151 ', S152', S153, S154) to perform.

That is, when the user selects the cleaning function (S151), the nozzle for performing the cleaning function is extended to a position corresponding to the human body, and the cleaning function is performed by spraying raw water (S152), and the user stops the button (stop key). Press () or when the injection time passes the preset time (S153), the injection of the raw water is finished and the nozzle for performing the cleaning function is returned to the original position (S154).

In the same way, when the user selects the bidet function (S151 '), the nozzle for performing the bidet function is extended to a position corresponding to the human body, and the cleaning function is performed by spraying raw water (S152'), and the user stops. When the button (stop key) is pressed or the spraying time has elapsed (S153), the spraying of the raw water is finished and the nozzle for performing the bidet function is returned to the original position (S154).

As such, the bidet using step S150 may include a bidet nozzle and a cleaning nozzle, that is, two nozzles that perform respective functions as the spray nozzle 151 to perform the bidet function and the cleaning function, but the spray nozzle. The configuration of 151 is not limited to this, and it is also possible to perform the cleaning performing steps S151 to S154 and the bidet performing steps S151 ', S152', S153 and S154 as one injection nozzle 151. That is, the nozzle unit 150 is provided with only one injection nozzle 151, and by controlling the moving distance of the injection nozzle 151 by driving the nozzle driving unit for moving it in the front and rear direction, both the cleaning function and the bidet function It is also possible to configure to perform.

As such, when only one injection nozzle 151 is provided, the nozzle unit 150 is simpler in configuration than the two injection nozzles 151 and only one injection nozzle 151 is moved. There is an advantage that control of 160 is easy. That is, when two injection nozzles 151 are provided, a complicated gear structure is required to move only one injection nozzle 151 as one nozzle driving unit 160 (motor), but one injection nozzle 151 is required. If only) is used, the structure for driving the injection nozzle 151 is simple, which facilitates the control of the nozzle driver 160. In addition, as described in the self-powered bidet 100 illustrated in FIG. 1, a DC motor is used as the nozzle driving unit 160, and the moving distance of the injection nozzle 151 (that is, the amount of rotation of the DC motor) is controlled by a variable resistor. In this case, power consumption can be reduced compared to the case of using a stepping motor.

On the other hand, the washing function performing step (S152) and bidet function performing step (S152 ') may further include a flow rate selection step for selecting the flow rate or the water pressure to be sprayed like a normal bidet. At this time, as described with reference to FIG. 6 in the self-powered bidet 100 shown in FIG. 1, the first flow path 145a which is always open as the flow control valve 144 for flow control and the first open by applying power When the latch valve including the two flow paths 145b is used, the flow rate can be adjusted through simple ON / OFF of the latch valve, thereby reducing the power consumption.

On the other hand, the control method (S100) of the self-powered bidet according to an aspect of the present invention between the voltage check step (S130) and the bidet use step (S150) by the user's selection, that is, after the voltage check step (S130) of the user Before performing the waiting step (S145) until the selection may further include a nozzle washing step (S140) step of supplying the raw water to the washing nozzle 152 to wash the injection nozzle 151. When the nozzle cleaning step (S140) is performed as described above, the user may wash the spray nozzle 151 before using the spray nozzle 151 to prevent the raw water from being sprayed while the spray nozzle 151 is contaminated. In addition, since the raw water is discharged in the nozzle washing process, power generation through the generator 120 may be additionally performed, thereby increasing the voltage of the charging unit 130.

In addition, even after the bidet use step (S150) it is possible to perform the nozzle washing step (S160) for supplying the raw water to the washing nozzle 152 to wash the injection nozzle (151). As such, when performing the nozzle cleaning step (S160), by cleaning the contaminants remaining in the spray nozzle 151 after the user's toilet can be prevented to maintain the spray nozzle 151 in a contaminated state, such a nozzle Since the raw water is discharged in the washing process, it is possible to additionally generate power through the generator 120, thereby increasing the voltage of the charging unit 130.

In addition, the control method of the self-powered bidet according to an aspect of the present invention (S100) is a departure detection step (S170) and the departure detection step (S170) for detecting that the user is leaving the toilet seat through the seating sensor (S) Thereafter, after the preset waiting time, a power cut-off step (S180) of blocking power supply from the charging unit 130 may be further included.

Of course, although not shown in detail, the departure detection step (S170) and the power-off step (S180) may be performed even if the user leaves the toilet seat after the waiting step (S145) without using the bidet or cleaning function.

As such, when a predetermined time elapses after the user leaves the toilet seat, power is supplied from the charging unit 130 to various electric components, such as various valves 143, 144, and 147, the nozzle driving unit 160, a control unit, and a display (not shown). By blocking the power consumption can be minimized.

In this case, the seating detection step (S110) described above allows the user to use the bidet after seating and at the same time, when the user's seating is detected in order to check the charging unit voltage necessary for the use of the bidet, the power from the charging unit 130 It is preferred to be configured to make a supply. At this time, the seating sensor (S) for detecting the user's seating preferably includes a contact switch that the user is pressed when seated on the toilet seat is mechanically switched. That is, in a conventional bidet, a capacitive sensor or an infrared sensor may be used as the seating sensor S, but after the user leaves the toilet seat, the power is forcibly cut off from the charging unit 130 and when the user sits down for reuse. It is preferable that a contact sensor such as a micro switch is used so that switching is performed by a load or pressure of a user so as to be detected mechanically.

Next, the control method (S100) applicable to the self-powered bidet according to the present invention will be described with reference to the configuration of the self-powered bidet 100 shown in FIGS. 1 to 5 and the flowcharts of FIGS. 9 and 10.

The control method (S100) of the self-powered bidet illustrated in FIG. 9 is similar to the control method (S100) of the self-powered bidet illustrated in FIG. 7, and as shown in FIG. 1, the generator 120, the charging unit 130, and the nozzle are shown in FIG. 1. Self-powered bidet 100 in which power generation of the generator 120 is performed through the raw water flowing through the nozzle flow path unit 140 including the unit 150 and the nozzle flow path unit 140, or FIGS. 2, 4 and 5. As shown in the generator 120, the charging unit 130, the nozzle unit 150, the nozzle passage section 140 and the tank passage section 190, including the tank passage section 190 and the nozzle passage section 140 Self-powered bidet 100 to generate power through the flowing raw water, or as shown in FIG. 3, the generator 120, the charging unit 130, the nozzle unit 150, the nozzle passage 140, and the water flow passage. Self-power generation in which power generation of the generator 120 is performed through the raw water flowing through the flushing flow path 190 'and the nozzle flow path 140, including the portion 190'. It relates to a control method of the bidet (100).

Specifically, the control method (S100) of the self-powered bidet shown in FIG. 9 is the same as the control method (S100) of the self-powered bidet shown in FIG. 7, and detects that the user is seated on the toilet seat through the seating sensor (S). When the seat detection step (S110) and the user's seat is detected to determine whether the charging unit voltage charged in the charging unit 130 is lower than the preset charging required voltage, if the charging unit voltage is lower than the charging required voltage generator 120 Voltage generation step (S130) for performing power generation and charging the charging unit 130, and bidet use step (S150) for supplying and spraying the raw water to the nozzle unit 150 according to the user's function selection, additionally Comprising a self-power generation determination step (S190) to determine whether the self-power generation is possible by comparing the power generation capacity generated in the generator 120 and the used capacity used for driving the bidet after being charged to the charging unit 130. It is configured.

That is, the control method (S100) of the self-powered bidet shown in FIG. 9 further includes a step (S190) of determining whether or not the self-powered bidet is controlled (S100). In order to avoid unnecessary duplication, the description of the same or similar contents will be omitted and only the differences will be described.

The step of determining whether the self-power generation is possible (S190) is the power generation capacity (charge capacity) to be charged in the charging unit 130 after being generated in the generator 120 and the used capacity used for driving the bidet after being charged in the charging unit 130 In comparison, self-power generation is not performed efficiently due to whether the self-powered bidet 100 is installed in a place where self-power generation is possible (for example, an area with high water pressure), or a change in water pressure or deterioration of the charging unit 130. It is a step of determining whether or not the situation.

In the case of the self-powered bidet 100 which generates power through the flow rate of the flow path inside the bidet, since the power generation amount is very small, it is necessary to minimize the use of power in the bidet, and furthermore, the power generation capacity through the generator 120 is increased. It should not be less than the capacity used by bidet use.

The power generation and charging of the self-powered bidet 100 according to the present invention discharges water from the storage tank 230 for washing the toilet, and then supplies the raw water back to the storage tank 230 or when the user flushes the toilet. When the raw water is supplied to the bowl 240 of the power generation / charging process, and the raw water is discharged through the nozzle unit 150 in the process of the user using the bidet (bidet function, cleaning function, nozzle cleaning function) When the power generation / charging is performed and when the user determines that the charging unit voltage after the seating is smaller than the required charging voltage, the raw water may be automatically discharged through the nozzle unit 150 to generate power / charging.

In general, when using a bidet, the water tank 230 or the bowl 240 is filled with water or the raw water flows through the generator 120 in the process of the user using the nozzle unit 150 through which power generation is The use of the bidet is made with this generating capacity (charge capacity). If the power generation capacity generated while the raw water is supplied to the storage tank 230 or the bowl 240 or the nozzle unit 150 is insufficient, sufficient electricity cannot be charged in the charging unit 130, and this restricts the use of the bidet. A lot.

Therefore, it is desirable that the power generation capacity (charge capacity) obtainable by the use of a conventional bidet is larger than the electric use capacity required for the use of the bidet.

This generation capacity is greatly affected by the raw water pressure. For example, in the high water pressure region, the pressure of the raw water is high, so that the speed of rotation of the impeller (aberration) provided in the generator 120 is high, thereby enabling a sufficient amount of power generation, while in a region where the water pressure is extremely low, Impeller (aberration) rotation speed is difficult to secure or sufficient power generation may not be achieved. In addition, since the raw water pressure is not always maintained, but fluctuates, power generation capacity also changes according to the change of raw water pressure.

Therefore, the power generation capacity is affected by the raw water pressure of the place where the self-powered bidet 100 is installed, and when the self-powered bidet 100 is installed in a place where the water pressure is low, the power generation capacity may not be higher than the used capacity. Of course, the control method according to the present invention is configured to perform power generation by discharging raw water through the nozzle unit 150 when the charging unit voltage charged in the charging unit 130 is lower than the required charging voltage, but the voltage check in the low water pressure region. Even if the step (S130) is performed, there is a problem that it is difficult to secure a sufficient power generation capacity. In this case, since the self-powered bidet 100 cannot be efficiently used, a separate power supply means such as a battery may be required.

In addition, the charging performance may decrease due to the continuous use of the charging unit 130, in this case, even in a high pressure region may not be filled with sufficient capacity. Therefore, even in such a case, the power generation capacity (charge capacity) may be smaller than the use capacity.

As such, if the power generation capacity (charging capacity) is not sufficient, the self-power generation possibility determination step (S190) may be performed at the stage after the user has seated on the toilet seat.

This self-development determination step (S190) may be performed as a process in any step after the departure detection step (S190) after the seating detection step (S110). For example, as shown in the upper part of FIG. 9, it may be performed in the waiting step S145 after the voltage checking step S130, or as in the lower part of the bidet using step S150 as shown in the lower part of FIG. 9. In step S165, if the self-power generation possibility determination step (S190) is finished, the process returns to the original step and subsequent steps are performed.

The self-power generation determination step (S190), as shown in Figure 10, the initial voltage measurement step (S191) for measuring and storing the initial charging unit voltage charged in the charging unit 130, and the number of times of bidet use of the user Integrating step (S192) to accumulate, and whether the number of times of bidet use of the user has reached a predetermined number of times (S193) and when the predetermined number of times when the comparison voltage to measure the charging unit voltage charged in the charging unit 130 in that state A comparison step (S195) of determining whether or not self-power generation is possible by comparing the measurement step (S194), the initial voltage measured in the initial voltage measurement step (S194) and the comparison voltage measured in the comparison voltage measurement step (S194). It can be configured to include.

Specifically, the initial voltage is measured at the time of initial use or the reset frequency of use (S191), and when the number of times of bidet use of the user does not reach the preset number of times, it is not enough to determine whether self-power generation is possible and returns to the original flow. (S199). That is, the determination of whether or not the self-power generation is possible, it is preferable to compare the average power generation capacity and the use capacity after the use of the bidet a plurality of times, if the number of times the bidet use times does not reach the preset number of times to determine whether the self-power generation is possible (S190 ) Will end.

If the number of times of bidet use of the user reaches a preset number of times, the charging unit voltage charged in the charging unit 130 is measured in that state (S194), and the measured comparison voltage is measured in the initial voltage measurement step (S194). It is compared with the initial voltage (S195). If the comparison voltage is greater than or equal to the initial voltage, it is determined that the power generation capacity (charge capacity) due to the use of the bidet is greater than the use capacity, so that self-power generation is possible (S196). If the power generation capacity (charge capacity) is insufficient, it is determined that the installation of a low water pressure or replacement of the charging unit 130 is required, and this is displayed through a display unit (not shown) installed in the bidet housing 180 or notified by an alarm. (S198).

In addition, when it is determined that the self-power generation is possible (S196), the number of times of use is reset (S197) and the process returns to the original stage (S199). At this time, it is also possible to reset the value of the initial voltage in the process of resetting the frequency of use.

On the other hand, the integration step of accumulating the number of times the bidet of the user (S192) is the user by supplying the raw water to the nozzle unit 150 according to the user's function selection after seating the toilet seat by accumulating the number of times the bidet function or cleaning function was performed Can be performed. On the contrary, the integration step of accumulating the number of times of using the bidet of the user (S192) is performed by accumulating the number of times the user's seat is detected through the seating sensor (S) since the seating function (S) does not always use the bidet function or the washing function. May be

As such, when the self-power generation is determined according to an embodiment of the present invention (S190), it is determined whether the power generation capacity (charge capacity) is sufficient, and if the power generation capacity is insufficient, the self-power generation is indicated. There is an effect that can confirm whether the bidet 100 is used stably.

While the present invention has been particularly shown and described with reference to particular embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention as defined by the following claims I would like to make it clear.
