Description

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

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

  The bidet includes a mechanical bidet where the user directly operates a lever or the like to spray water, and various operations that the bidet is equipped with when the user presses a button with a specific function, such as a bidet function, an anus cleaning function, a nozzle There are electronic bidets that automatically perform cleaning and drying functions.

  However, since the mechanical bidet does not have a separate external power supply, there is an inconvenience that the user has to adjust all operations, and the electronic bidet cannot operate unless an external power supply is connected. It cannot be used in areas where there are no supply facilities or where power supply connection is difficult.

  In order to solve the problem of the power connection of the electronic bidet, a method using various functions of the bidet using a dry battery can be considered. However, in such a case, the dry battery must be replaced as needed. There is.

  In order to solve such problems, a power-generating bidet that provides electricity by generating power using the water pressure of raw water supplied from a water tap or the like has been proposed. Such a power-generating bidet is provided with a generator directly on a pipe connecting between a water storage tank for toilet flushing and a raw water inflow portion such as a water tap, but the generator is provided on a pipe provided outside the bidet. The work of connecting the generator wiring to the charging part inside the bidet with a lot of labor and difficulty is involved. In addition, since the charging unit that stores the electricity generated by the generator is located inside the bidet body, the wiring that electrically connects 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 loss of aesthetics and the possibility that the external wiring may be disconnected due to carelessness or mischief of the user, or that the user may crawl and fall.

  In particular, there is a problem in that a toilet without a water storage tank cannot be provided with the above-mentioned power generation bidet.

  On the other hand, the power generation bidet has a very small amount of electricity generated by the generator, so it is necessary to minimize the consumption power. However, standby power is supplied to various electrical components to which electricity is supplied. , Too much power wasted. In particular, the usage time of the bidet is only a part of the day, and considering that the waste of a considerable amount of standby power for using the bidet is not sufficient, the generation capacity is inefficient. This is a significant obstacle to the spread of power generation bidets.

  In the case of an electronic bidet, various valves are provided to inject water, and the injection water pressure is adjusted by a flow rate adjustment valve. However, since such a flow rate adjusting valve adjusts the degree of opening and closing of the valve through driving of a motor, a lot of electric power is consumed. Therefore, it cannot be used for a power generation bidet having a small power generation capacity.

  In particular, the power generation type bidet proposed in the past generates power only by using water supplied to the water storage tank, so that the power generation capacity is not sufficient and the bidet cannot be used in a state where the charging voltage is low. There is a problem.

  The present invention is for solving at least a part of the above-mentioned problems, and when the charged voltage is not sufficient for the use of the bidet, it is possible to generate electricity and to use the bidet stably. An object is to provide a bidet control method.

  Another object of the present invention is to provide a method for controlling an in-house power generation bidet that can generate power even in a toilet without a water storage tank.

  Moreover, an object of this invention is to provide the control method of the private power generation bidet which can confirm the abnormality propriety of a charging part as one side surface.

The control method (S100) will be described.

  First, a self-powered bidet 100 to which the method for controlling a self-powered bidet according to the present invention can be applied will be described with reference to FIGS.

  As shown in FIG. 1, the in-house power generation bidet 100 to which the control method according to the present invention can be applied generates power using the raw water inflow portion 110 into which the raw water flows and the raw water into the raw water inflow portion 110. A generator 120; a charging unit 130 for storing electricity generated by the generator 120; a nozzle unit 150 configured to inject raw water flowing into the raw water inflow unit 110 into a human body; and the generator A nozzle flow path 140 is provided between the generator 120 and the nozzle unit 150 so that raw water that has passed through the nozzle 120 is supplied to the nozzle unit 150, and the nozzle flow is performed so that the generator 120 is driven. A control unit C that controls opening and closing of the flow path of the path unit 140 may be further included. In addition, as shown in FIG. 2, the private power generation bidet 100 to which the control method according to the present invention can be applied supplies the raw water that has passed through the generator 120 to the water storage tank 230 for toilet bowl cleaning. A tank flow path 190 provided between the generator 120 and the water storage tank 230 can also be included. In addition, as illustrated in FIG. 3, the private power generation bidet 100 to which the control method according to the present invention can be applied is configured so that the raw water that has passed through the power generator 120 is supplied to the bowl 240 of the toilet bowl. A water flow channel portion 190 ′ provided between the bowls 240 may also be included.

  At this time, the private power generation bidet 100 shown in FIG. 2 is only shown in FIG. 1 only in that it further includes a tank flow path 190 provided to supply raw water that has passed through the generator 120 to the water storage tank 230. The self-powered bidet 100 is different from the illustrated self-powered bidet 100. The self-powered bidet 100 illustrated in FIG. 1 is different from the self-powered bidet 100 illustrated in FIG. 1 only in that it further includes a ', and therefore, the self-powered bidet 100 illustrated in FIGS. 1 to 3 will be described together.

  The raw water inflow section 110 receives a raw water supply from a raw water supply section 210 provided outside the bidet housing 180 such as a water pipe or a pipe connected thereto, and is a connection port for connection with a water pipe or the like. Is provided.

  The raw water that has flowed into the raw water inflow section 110 flows into the generator 120 to generate power. As an example, the generator 120 used in the present invention includes an impeller (water turbine), and when the raw water flows into the generator 120, the impeller rotates, and power can be generated through this. In addition, the charging unit 130 is electrically connected to the generator 120 so as to store electricity generated by the generator 120, and the electricity charged in the charging unit 130 is a use of a bidet, that is, a nozzle. It is used for driving the driving unit 160 and various valves 143, 144, 147, the operation of the sensing sensor S, and the like. As described above, since the configuration of the generator 120 that generates power by the flow of fluid and the charging unit 130 that charges electricity generated through the fluid flow are known in various forms, a detailed description thereof will be omitted.

  On the other hand, the raw water that has passed through the generator 120 is supplied to the nozzle unit 150 through the nozzle channel unit 140. At this time, the nozzle channel part 140 may be provided with various valves 143, 144 and 147 in order to supply or block the raw water to the nozzle part 150, and the specific configuration thereof is shown in FIGS. It is not limited to the example illustrated in FIG.

  In addition, the nozzle unit 150 may include only the injection nozzle 151 for cleaning the anus of the human body and / or the local part of the woman, but the outer surface of the injection nozzle 151 (in particular, the upper surface of the injection nozzle) is cleaned. As described above, the cleaning nozzle 152 for injecting raw water onto the upper surface side of the injection nozzle 151 may be included.

  At this time, as shown in FIG. 1 to FIG. 3, the nozzle flow path part 140 is provided with an injection nozzle flow path 146 for supplying raw water to the injection nozzle 151, and for supplying raw water to the cleaning nozzle 152. A cleaning nozzle channel 148 can be provided. The injection nozzle channel 146 is provided with a first on-off valve 143 that opens and closes the injection nozzle channel 146, and a flow rate adjustment valve 144 is provided so as to adjust the flow rate of the raw water that has passed through the first on-off valve 143. You can also. The cleaning nozzle channel 148 may be provided with a second on-off valve 147 that opens and closes the cleaning nozzle channel 148.

  At this time, the first on-off valve 143 and the second on-off valve 147 are preferably configured as latch valves that are turned on / off by an electrical signal in order to minimize power consumption. Since the configuration of such a latch valve is known in various forms and structures, a specific description is omitted.

  Further, the flow rate adjusting valve 144 can also be configured by a latch valve capable of adjusting the flow rate by being turned on / off by an electrical signal. As shown in FIGS. 1 to 3, the flow control valve 144 has a single inflow path through which raw water flows and a plurality of water discharge paths 145a and 145b that are selectively opened so that the flow rate can be adjusted. A main body 144a having a plurality of water discharge channels 145a and 145b can be provided.

  More specifically, as shown in FIG. 6 as an example, the flow rate adjusting valve 144 is connected to the nozzle flow path 141 and is always open to the inflow path 310 into which the raw water that has passed through the generator 120 flows. Thus, it can be configured by a latch valve including a first flow path 145a through which raw water can be discharged and a second flow path 145b opened by applying power.

  The flow rate adjusting valve 144 has a coil wound around a solenoid SL positioned inside the upper housing 327, and a plunger 322 and an iron core 329 are disposed inside the solenoid SL, and a permanent magnet is disposed above the iron core 329. M is disposed, and a spring 325 is disposed below the iron core 329 so as to push the plunger 322 toward the water outlet 314.

  The lower housing 328 is formed with an inflow path 310 through which the raw water that has passed through the generator 120 is connected to the nozzle flow path 141 and a second flow path 145b through which the raw water that has passed through the space 330 is discharged. Can. At the end of the inflow path 310 and the second flow path 145b, a rubber-made diaphragm 320 having elasticity, and a plastic support member formed with an inlet 311 and a water outlet 314 sandwiched by the diaphragm 320 are formed. 321 are provided. The inflow path 310 communicates with the space 330 through the inflow port 311, and the second flow path 145 b communicates with the space 330 through the water outlet 314.

  The space 330 between the support 321 and the upper housing 327 is connected to the first flow path 145a, and a spring functioning as a stopper 332 is attached to the upper surface of the support 321. The stopper 332 has a radius larger than the radius of the plunger 322, and when the support body 321 is lifted together with the diaphragm 320, the stopper 332 comes into contact with the lower surface of the upper housing 327 and restricts the rising positions of the support body 321 and the diaphragm 320.

  Referring to FIG. 6, the flow rate adjusting valve 144 according to an embodiment is connected to the inflow path 310 and the first flow through the space portion 330 even when the plunger 322 is in the OFF position where the plunger 322 is lowered to block the water outlet 314. Since the path 145a communicates, when the first on-off valve 143 is opened (ON) and the raw water flows into the inflow path 310, the raw water can be discharged through the first flow path 145a. Further, when the flow rate adjustment valve 144 is turned on (ON), the plunger 322 is raised and the water outlet 314 is opened, so that the raw water flowing in through the inflow port 311 enters the second flow path 145b through the water outlet 314. It is leaked further. Accordingly, the raw water discharged from the first flow path 145a and the second flow path 145b is discharged through the combined water discharge path 144b of FIGS. 1 and 2 and then supplied to the injection nozzle 151. Therefore, when the flow rate adjustment valve 144 is in the on (ON) state, as compared with the case of the off (OFF) state, a larger flow rate can flow through the second flow path 145b.

  As described above, when the latch valve as the first on-off valve 143 and the latch valve as the flow rate adjusting valve 144 are used, only the first on-off valve 143 is required when low water pressure (low flow) injection is required by the injection nozzle 151. When the high water pressure (high flow rate) injection is required, the flow rate adjustment valve 144 is further opened with the first on-off valve 143 opened. Therefore, by simply turning on / off the flow control valve 144, the injection water pressure can be realized in multiple stages, so that the effect of maximizing the power consumption can be obtained.

  On the other hand, the nozzle channel section 140 adjusts the opening / closing amount of the valve to adjust the inflow amount of the raw water, or when an abnormality occurs in the parts constituting the channel or when the parts need to be replaced. A manual valve 142 may be provided for forcibly shutting off, and such a manual valve 142 is normally kept open.

  Further, the spray nozzle 151 has a bidet nozzle and an anus cleaning nozzle for performing respective functions in order to perform a bidet function for cleaning a local part of a woman and an anal cleaning function for cleaning an anus of a human body, that is, 2 One nozzle can be provided. However, the spray nozzle 151 may be composed of only one nozzle.

  The nozzle unit 150 may include a nozzle driving unit 160 that moves the spray nozzle 151 in the front-rear direction. At this time, by using a DC motor for the nozzle driving unit 160, power consumption can be reduced as compared with the case of using a stepping motor.

  Specifically, the efficiency of a DC motor is 75% to 80%, but since a stepping motor must use a current having a plurality of phases for precise position control, the current use efficiency is higher than that of the DC motor described above. It drops by 20-25% and is at the 50-60% level. Therefore, when a direct current motor is used as in one embodiment of the present invention, it has an excellent effect in terms of power consumption compared to the case where a stepping motor is used, and thus is suitable for a private power generation bidet. As such a direct current motor, a brush direct current motor (Brush DC Motor) or a brushless direct current motor (Brushless DC Motor, BLDC motor) can be used.

  Further, the movement of the injection nozzle 151 by the driving of the nozzle driving unit 160 can be adjusted using a variable resistor linked with the DC motor. Since a technique for controlling the amount of rotation of the DC motor by a variable resistor is known, a specific description is omitted.

  On the other hand, when the nozzle unit 150 is provided with only one injection nozzle 151, the control of the nozzle driving unit 160 so that the movement distance of the injection nozzle 151 is different, so that the anal cleaning function and the bidet can be performed through one injection nozzle 151. Functions can be implemented. As described above, when only one injection nozzle 151 is provided, the configuration of the nozzle unit 150 is simpler than when two injection nozzles 151 are provided, and only one injection nozzle 151 is moved. There is an advantage that the control of the unit 160 is easy. That is, when two injection nozzles 151 are provided, in order to move only one of the two injection nozzles 151 by one nozzle driving unit (motor) 160, a complicated gear structure is necessary. When only one injection nozzle 151 is used, the structure for driving the injection nozzle 151 is simple, which makes it easy to control the nozzle driving unit 160. Further, as described above, when the moving distance of the injection nozzle 151 (that is, the amount of rotation of the DC motor) is controlled by a variable resistance using a DC motor as the nozzle driving unit 160, compared to the case of using a stepping motor. Power consumption can be reduced.

  On the other hand, the tank flow path 190 shown in FIG. 2 supplies the raw water that has passed through the generator 120 to the water storage tank 230 for cleaning the toilet bowl. It is comprised so that it may be branched from and connected with the water storage tank 230. As an example, the tank channel unit 190 may include a tank channel 191 branched from the nozzle channel 141 and a connection port 192 so that the tank channel unit 190 can be connected to the water storage tank 230. In this way, by providing the tank flow path 190 at the rear end of the generator 120, after the water stored in the water storage tank 230 has moved to the bowl of the toilet bowl, the water is supplied again to the water storage tank 230. The raw water passes through the generator 120, thereby generating power.

  Further, the water flow passage portion 190 ′ illustrated in FIG. 3 supplies the generator 120 so that the raw water that has passed through the generator 120 is supplied to the bowl 240 of the toilet bowl in which flush water for toilet flushing is collected. It is configured to be branched from the nozzle channel part 140 at the rear end and connected to the bowl 240. As an example, the water flow channel portion 190 ′ may include a water flow channel 191 ′ branched from the nozzle flow channel 141 and a connection port 192 ′ so as to be connected to the bowl 240. In this way, by providing the water flow channel portion 190 ′ at the rear end of the generator 120, when the user flows water before or after using the toilet bowl, the raw water is supplied in the process of supplying water to the bowl 240. Passing through the generator 120, power is generated.

  As described above, since the private power generation bidet 100 shown in FIG. 1 generates the power from the generator 120 while discharging the raw water through the nozzle unit 150, it is possible to install the private power generation bidet 100 in a toilet without the water storage tank 230. In particular, power generation is performed using raw water sprayed through the spray nozzle 151 when using the bidet or raw water discharged through the cleaning nozzle 152 for nozzle cleaning, and the power generation capacity is not sufficient or the voltage of the charging unit 130 is low. In this case, a large amount of raw water is discharged for a sufficient time through the nozzle unit 150, for example, the washing nozzle 152 (for example, 1 liter of raw water inside and outside per minute is discharged for 1 to 2 minutes), thereby generating a sufficient amount of power. It becomes possible.

  In addition, the private power generation bidet 100 illustrated in FIG. 2 not only generates power using raw water injected through the injection nozzle 151 when using the bidet but also raw water discharged through the cleaning nozzle 152 for cleaning the nozzle, as well as a water storage tank 230. Since power generation using raw water supplied to the plant is performed, it is possible to generate sufficient capacity. In addition, when the voltage of the charging unit 130 is low, power generation is performed through a large amount of raw water that is forcibly discharged through the nozzle unit 150, for example, the cleaning nozzle 152. The effect that can be supplemented is obtained.

  In addition, the private power generation bidet 100 illustrated in FIG. 3 not only generates power using raw water injected through the injection nozzle 151 when using the bidet, but also raw water discharged through the cleaning nozzle 152 for cleaning the nozzle, Since power generation using the supplied raw water is performed, power generation with a sufficient capacity becomes possible. In addition, when the voltage of the charging unit 130 is low, power generation is performed through a large amount of raw water that is forcibly discharged through the nozzle unit 150, for example, the cleaning nozzle 152. The effect that can be supplemented is obtained.

  As described above, the private power generation bidet 100 to which the control method according to the present invention can be applied does not generate power only through the raw water supplied to the water storage tank 230 or the bowl 240 of the toilet bowl, but to the nozzle unit 150 when the bidet is used. Power generation capacity is increased and power supply capacity is always maintained sufficiently to generate power through the supplied raw water and to generate power through the raw water that is forcibly discharged to the nozzle section 150 when power generation is required. There is an effect that can be.

  On the other hand, the control unit C is provided in the nozzle channel 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 a preset required charging voltage. The generator 120 can be driven by controlling the opening and closing of the various valves 143, 144, and 147. Such a required charging voltage can be set to an appropriate value in consideration of electric power required when using the bidet function.

  That is, if the user cannot use the bidet function and / or anal washing function after the stool and the power supply with sufficient capacity is not secured, the charging unit 130 needs to be charged. The part C determines whether the voltage of the charging unit 130 charged in the charging unit 130 is higher than a preset required charging voltage, and if the charging unit 130 voltage is lower than the required charging voltage, Power is generated through the unit 150. Specifically, the control unit C causes the generator 120 to generate power by opening the channel of the nozzle channel unit 140 so that the raw water is discharged from the nozzle unit 150 to the bowl of the toilet bowl. . That is, since the generator 120 does not generate power unless a fluid flows therein, in the present invention, when the voltage of the charging unit 130 is not sufficient, the nozzle flow path unit 140 is used for power generation of the generator 120. It opens automatically and the raw water is poured from the nozzle part 150 into the bowl of the toilet bowl.

  The nozzle unit 150 may include an injection nozzle 151 for cleaning the anus and / or the female part of the human body as described above, and the control unit C may extend the injection nozzle 151 toward the human body. By controlling the opening and closing of the first on-off valve 143 provided in the nozzle driving unit 160 and the nozzle flow path unit 140 so that the injection is performed in a state where it is not exposed to the outside of the bidet housing 180, the raw water Can be prevented from being directly injected into the human body. Further, even if the injection nozzle 151 is not exposed to the outside of the bidet housing 180, the front end of the injection nozzle 151 may be used in order to prevent the phenomenon that the raw water splashes on the human body or the raw water penetrates into the bidet housing 180. A separate cover can also be attached to.

  Further, when the nozzle unit 150 includes not only the spray nozzle 151 but also the cleaning nozzle 152, the raw water is ejected through the cleaning nozzle 152 since the jet direction of the raw water at the cleaning nozzle 152 is the lower direction. It is preferable to generate electricity. At this time, the controller C can generate power by the generator 120 by opening the second on-off valve 147 so that the raw water flows through the cleaning nozzle channel 148.

  That is, when the raw water is jetted through the cleaning nozzle 152, the phenomenon of water splashing to the user can be minimized as compared with the case where the raw water is discharged through the jet nozzle 151, thereby generating power while minimizing the user's inconvenience. There is an advantage that can be. In addition, when the raw water is discharged through the cleaning nozzle 152, it is possible to increase the flow rate of the raw water discharge since the splashing of water is minimized, and it is possible to wash the spray nozzle 151 incidentally. There are advantages.

  On the other hand, unlike the above, the control unit C is configured so that various valves 143 and 144 provided in the nozzle flow path unit 140 are discharged so that raw water is discharged through the nozzle unit 150 when a preset condition is satisfied. The generator 120 can also be driven by controlling the opening / closing of 147. For example, the control unit C can sense the number of times that the user has used the bidet through the sensing sensor S and the like, and can cause the generator 120 to generate power. When the user does not use the bidet for a long time, the charging unit When a certain period of time elapses so that 130 discharge does not occur, the generator 120 can generate power.

  On the other hand, the self-powered bidet 100 to which the control method according to the present invention can be applied is a seating detection sensor that senses that the user is seated on the toilet seat and generates a seating signal, or the user approaches the bidet within a certain distance. And a sensor S that senses that the user intends to use the bidet, such as a proximity sensor that senses the image and a receiver (not shown) that receives an operation signal transmitted by the user using the remote control. it can.

  At this time, as the seating detection sensor, a sensor that measures an electrical change caused by the user's seating such as a capacitance sensor can be used, and the user can sit on the toilet seat or press the switch like a micro switch. The type, sensing method, and installation position are not particularly limited as long as they can sense the user's seating, such as a contact switch that can be switched at the time.

  In addition, as the proximity sensor, various known sensors such as an infrared sensor can be used to sense that the user approaches the bidet within a certain distance.

  When the user senses that the user intends to use the bidet through the sensor S (for example, when the user is seated or approaches the bidet or receives a remote control operation signal), the control unit C detects the charging unit. Power is supplied from 130 to various electrical components, for example, various valves 143, 144, and 147, a nozzle driving unit 160, a display (not shown), and the like. On the other hand, when it is detected by the detection sensor S that the user has finished using the bidet (for example, the user has left the toilet seat, left the bidet, or received a remote control end signal), By cutting off the power supply from the charging unit 130 after the set standby time, power consumption when the user does not use the bidet can be minimized.

  That is, power consumption can be minimized by blocking the supply of power from the charging unit 130 to various electrical components after a certain period of time has elapsed after the user has finished using the bidet, such as leaving the toilet seat. It becomes like this. At this time, in order to minimize the power consumed after the user finishes using the bidet, it is preferable to completely shut off the power supply from the charging unit 130 to the electrical component. However, as described later, the user The power supply to the sensor S should be kept to a minimum so that the user can detect when he / she wants to use the bidet, such as sitting on the toilet seat, approaching the bidet or using a remote control. Is preferred.

  On the other hand, it is preferable that when the user senses that he / she wants to use the bidet, such as when the user sits on the toilet seat or approaches the bidet through the sensor S, the bidet is automatically brought into a usable state. For this reason, it is preferable that power is supplied from the charging unit 130 to various electrical components when the sensor S senses that the user intends to use the bidet.

  At this time, it is preferable that the detection sensor S includes a contact type switch that is mechanically switched by being pushed by the user sitting on the toilet seat. That is, if a contact sensor such as a micro switch that is switched by the user's pressure is used as the detection sensor S, the power supply from the charging unit 130 can be completely shut off after the user leaves the toilet seat. When the user is seated again for the use of the bidet, switching is performed immediately, and power supply from the charging unit 130 to various electrical components can be resumed.

  On the other hand, in order to maximize the power generation in the generator 120, the raw water supplied to the water storage tank 230 must minimize the occurrence of pressure or flow loss, but the raw water pressure of the raw water supply unit 210 remains as it is in the nozzle flow path. When added to the component parts of the unit 140, there is a possibility that the component parts may fail or the service life may be shortened.

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

  At this time, the ratio of the diameter of the nozzle channel 141 to the diameter of the tank channel 191 is preferably 1: 1.2-5. If the diameter of the tank flow path 191 is smaller than 1.2 times the diameter of the nozzle flow path 141, the raw water pressure flowing into the nozzle flow path 141 will increase, so that the components provided in the nozzle flow path section 140 May cause damage or shortened life. On the other hand, when the diameter of the tank channel 191 exceeds five times the diameter of the nozzle channel 141, the diameter of the nozzle channel 141 is too small compared to the diameter of the tank channel 191. Since the injection of 151 cannot be implemented well and the flow rate of the raw water discharged in the power generation process through the nozzle unit 150 is small, sufficient power generation cannot be performed.

  For the reason described in the tank flow path 190 described above, the pressure of the raw water supplied to the nozzle flow path 140 is relatively maintained while maintaining the pressure of the raw water supplied to the water flow path 190 'in a high state. In order to reduce the pressure, the diameter of the water flow path 191 ′ provided in the water flow path part 190 ′ is preferably larger than the diameter of the nozzle flow path 141 provided in the nozzle flow path part 140.

  Meanwhile, the private power generation bidet 100 to which the control method according to the present invention can be applied includes the generator 120, the charging unit 130, the nozzle unit 150, and the nozzle channel unit 140 inside the bidet housing 180 as illustrated in FIG. 1. By providing them integrally, piping or components for power generation are not exposed to the outside, so that 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 inflow unit 110 only. Therefore, the effect that the installation of the private power generation bidet is extremely easy can be obtained. As shown in FIG. 2, when the tank channel 190 is provided, not only the configuration illustrated in FIG. 1 but also the configuration of the tank channel 190 is provided inside the bidet housing 180. The effect of improving the aesthetics and the ease of installation work can be achieved. In addition, as shown in FIG. 3, when the water flow passage portion 190 ′ is provided, not only the configuration shown in FIG. 1 but also the water flow passage portion 190 ′ is provided inside the bidet housing 180. By providing, the effect of appearance improvement and ease of installation work can be achieved.

  On the other hand, if high-pressure raw water is directly flowed into the generator 120, considerable noise is generated due to the rapid rotation of the impeller. Therefore, in high-pressure areas, it is possible to secure power generation capacity while minimizing noise generated by private power generation. Thus, in order to prevent damage to the components provided in the nozzle flow path part 140, it is necessary to appropriately reduce the raw water pressure. For this purpose, it is preferable to provide a pressure reducing valve 115 between the raw water inlet 110 and the generator 120 to reduce the raw water pressure below a certain level.

  Next, a self-powered bidet according to another embodiment will be described with reference to FIGS.

  4 and 5, the self-powered bidet 100 shown in FIGS. 1 to 3 is fed into the raw water inflow portion 110 through which raw water flows and the raw water inflow portion 110. A generator 120 that generates power using raw water, a charging unit 130 that stores electricity generated by the generator 120, and a nozzle unit 150 configured to inject the raw water that has flowed into the raw water inflow unit 110 into the human body. And a nozzle channel part 140 provided between the generator 120 and the nozzle part 150 so as to supply raw water that has passed through the generator 120 to the nozzle part 150. The tank flow path 190 provided between the generator 120 and the water storage tank 230 and the electric power of the charging unit 130 so as to supply the passed raw water to the water storage tank 230 for toilet flushing. The controller C further opens the flow path of the nozzle flow path portion 140 so that the raw water is discharged through the nozzle portion 150 when the charging voltage is lower than the required charging voltage, and the generator 120 is driven. Can be included. Although not shown separately, as shown in FIG. 3, the generator 120 and the tank 120 are configured to supply the raw water that has passed through the generator 120 to the bowl 240 of the toilet bowl, instead of the tank channel portion 190. When the voltage of the water flow passage portion 190 ′ provided between the bowls 240 and the charging portion 130 is lower than the voltage required for charging, the nozzle passage portion 140 is discharged so that the raw water is discharged through the nozzle portion 150. The control part C which opens the flow path and drives the generator 120 may be further included.

  However, in comparison with the private power generation bidet illustrated in FIGS. 1 to 3, the private power generation bidet 100 illustrated in FIGS. 4 and 5 flows in from the warm water inflow portion 170 into which the hot water flows and the raw water inflow portion. The mixing valve 141a provided at the rear end of the generator 120 is provided so as to mix the raw water and the warm water flowing in from the warm water inflow portion 170, and the raw water that has passed through the mixing valve 141a is supplied to the nozzle portion 150. There is a difference in supplying to In order to avoid unnecessary duplication, detailed description of the same or similar parts is omitted, and only the hot water inflow portion 170 and the mixing valve 141a and the configuration related thereto will be described.

  As shown in FIGS. 4 and 5, the hot water inflow part 170 is connected to a hot water supply part 220 such as a boiler pipe capable of generating or supplying hot water through a connection port, and the hot water is supplied to the nozzle channel part 140. Configured to supply. At this time, the hot water flow path 171 is joined to the nozzle flow path 141 at the rear end of the generator 120, thereby preventing the magnet of the generator 120 from being damaged by the hot water flowing into the hot water inflow portion 170. Can do.

  Moreover, the warm water that has passed through the warm water flow channel 171 flows into the mixing valve 141 a so as to be mixed with the raw water that has flowed in from the raw water inflow portion 110. At this time, the mixing valve 141a may be configured to be able to manually or automatically adjust the mixing condition of hot water and raw water (cold water) in order to adjust the temperature of the water jetted through the jet nozzle 151.

  As described above, when the hot water inflow portion 170 is provided, the temperature of the water sprayed through the spray nozzle 151 can be adjusted. In particular, the mixing valve 141a is provided at the rear end of the generator 120, thereby generating power with the hot water. The phenomenon that the magnet of the generator 120 is damaged is prevented, and the effect that the generator 120 can be used smoothly is obtained.

  On the other hand, in the case where private power generation is performed in a high water pressure area (for example, a water pressure of 5 kgf or more), the power generation capacity can be sufficiently increased. However, if the high water pressure raw water is directly flowed into the generator 120, the impeller is rapidly There is a problem that considerable roaring occurs due to the rotation. Therefore, it is necessary to appropriately reduce the raw water pressure so that the generation capacity can be secured while minimizing the noise caused by private power generation in the high water pressure area. For this purpose, as shown in FIG. 4, it is preferable to provide a pressure reducing valve 115 between the raw water inlet 110 and the generator 120 to reduce the raw water pressure to a certain level (for example, 3 to 4 kgf) or less.

  On the other hand, in the low water pressure area, the noise of the generator 120 due to the raw water pressure is not so loud that it is possible to not provide a pressure reducing valve. Therefore, as shown in FIG. 5, the pressure reducing valve 115 may be provided in the nozzle flow path 140 at the rear end of the generator 120. On the other hand, as illustrated in FIG. 5, a check valve 111 may be provided in the raw water inflow portion 110 so that the raw water flowing into the raw water inflow portion 110 does not flow backward.

  Next, referring to the configuration of the self-powered bidet 100 shown in FIGS. 1 to 5 and the flowcharts of FIGS. 7 and 8, the method for controlling the self-powered bidet according to one embodiment of the present invention (S100). explain.

  First, a method for controlling a private bidet (S100) according to an embodiment of the present invention includes a generator 120, a charging unit 130, a nozzle unit 150, and a nozzle channel unit 140, as shown in FIG. The generator through the raw water flowing through the flow path 140 (hereinafter simply expressed as “raw water” including the state in which the raw water and hot water are mixed as shown in FIGS. 4 and 5 in the description of the control method). The self-powered bidet 100 that generates 120 power, or the generator 120, the charging unit 130, the nozzle unit 150, the nozzle channel unit 140, and the tank channel unit 190 as shown in FIGS. A self-generating bidet 100 in which the power generator 120 generates power through raw water flowing through the tank flow path 190 and the nozzle flow path 140, or the generator 120, the charging section as shown in FIG. 30, the power generation of the generator 120 through the raw water flowing through the water flow channel unit 190 ′ and the nozzle flow channel unit 140 ′, including the nozzle unit 150, the nozzle flow channel unit 140, and the water flow channel unit 190 ′. The present invention relates to a method for controlling the bidet 100.

  As shown in FIG. 7, the method for controlling a private power bidet (S100) according to an embodiment of the present invention includes a use sensing step (S110) for sensing that a user intends to use a bidet, and a charging unit. Includes a voltage check step (S130) in which power is generated through the generator 120 when the voltage is lower than the required charging voltage. After the voltage check step (S130), raw water is supplied to the nozzle unit 150 by the user's function selection. And a bidet use step (S150) of jetting.

  In the use detection step (S110), the user sits on the toilet seat (not shown) through the detection sensor S, detects that the user is approaching the bidet, or is transmitted by the remote controller so that the user can use the bidet. Whether or not the received operation signal is received is detected. Such a sensor S may be a sensor that measures an electrical change due to the user's seating, such as a capacitance sensor, or may be switched when the user is seated on the toilet seat, such as a microswitch. It is also possible to use a contact type switch that can be used, an infrared sensor that senses the approach of the user, and a receiving unit (not shown) that receives an operation signal transmitted by the user with a remote control. As long as it can detect whether the user intends to use the bidet, the type, detection method, and installation position are not particularly limited.

  As described above, when it is detected whether or not the user intends to use the bidet through the sensor S, the voltage charged in the charging unit 130 is checked. When the person cannot secure a sufficient power supply for using the bidet function and / or anal washing function after the stool, the voltage check stage (S130) for charging the charging unit 130 is performed.

  Specifically, in the voltage check step (S130), when it is detected that the user intends to use the bidet (sitting on the toilet seat, approaching the bidet, receiving a remote control operation signal, etc.), the charging unit 130 receives the signal. It is determined whether the charged current voltage of the charging unit is lower than a preset charging required voltage, and if the charging unit voltage is lower than the charging required voltage, the power is generated through the generator 120 to perform charging. The unit 130 is charged.

  As shown in FIG. 8 as an example, the voltage check step (S130) includes a voltage measurement step (S131) for measuring the voltage of the charging unit charged in the charging unit 130, and the voltage of the charging unit is set in advance. A chargeability determination step (S132) for determining whether the voltage is higher than the set required charge voltage, and a power generation step (S133) for generating power when the voltage of the charging unit is lower than the required charge voltage. Can be configured.

  At this time, in the power generation stage (S133), power is generated by opening the flow path of the nozzle flow path section 140 so that the raw water is discharged from the nozzle section 150 to the bowl of the toilet bowl. That is, since the generator 120 does not generate power unless a fluid flows into the generator 120, in the case of the present invention, if the voltage of the charging section is not sufficient, the nozzle flow path section 140 is automatically set for power generation by the generator 120. The raw water is poured from the nozzle part 150 to the bowl of the toilet bowl.

  The nozzle unit 150 may include an injection nozzle 151 for cleaning the anus of the human body and / or a female part. In the power generation step (S133), the injection nozzle 151 is not expanded toward the human body. Since injection is performed, it can prevent that raw | natural water is injected directly on a human body.

  Unlike the above, when the nozzle unit 150 includes not only the injection nozzle 151 but also the cleaning nozzle 152, the raw water is discharged through the cleaning nozzle 152 because the raw water is ejected downward in the cleaning nozzle 152. It is preferable to generate power through this. That is, when the raw water is jetted through the cleaning nozzle 152, the phenomenon of water splashing to the user can be minimized as compared with the case where the raw water is discharged through the jet nozzle 151, thereby increasing the raw water discharge flow rate. In addition, there is an advantage that the injection nozzle 151 can be cleaned incidentally.

  Such a power generation step (S133) is continued until the voltage of the charging unit becomes equal to or higher than the necessary voltage for charging (S134).

  However, when the performance of the charging unit 130 is degraded or malfunctioned, the voltage charged in the charging unit 130 may not reach the required charging voltage even after the long-time power generation stage (S133). In order to determine the abnormality of the charging unit 130, it is determined whether the power generation stage (S133) is longer than the reference time (S136), and the charging unit voltage needs to be charged for the reference time. If the voltage cannot be reached, it is determined that the charging unit 130 is abnormal, and this is displayed on the display (S137), and then the voltage check stage is terminated (S138).

On the other hand, the voltage check stage (S130) does not immediately end the power generation stage (S133) after the voltage of the charging unit being charged has reached the required voltage for charging, during the preset power generation maintenance time. An additional power generation step (S135) in which the nozzle unit 150 further discharges raw water to perform additional power generation may be included. By performing the additional power generation step (S135) in this way, even when the user uses the bidet function or the anal cleaning function a plurality of times, the nozzle unit 150 can be stably operated. In particular, by setting the voltage of the charging unit to a certain level higher than the required charging voltage through additional power generation, it is possible to prevent power generation every time the user is seated on the toilet seat. Can be minimized. Such a power generation maintenance time can be changed according to the raw water pressure and the generator performance, but can be set to such an extent that power can be generated after the user uses the bidet a plurality of times.

  Further, in the case of the additional power generation stage (S135), it can be performed by injecting raw water with the injection nozzle 151 as in the above-described power generation stage (S133). In consideration of minimizing the phenomenon of water splash, maximizing the flow rate of the raw water discharge, cleaning of the spray nozzle 151, etc., it is more preferable to generate power by discharging the raw water to the cleaning nozzle 152.

  Then, as shown in FIG. 8, after the voltage check stage (S 130) of the charging unit 130 is completed, a standby stage (S 145) is performed until the user selects a function. If there is a selection, a bidet use step (S150) is performed.

  In the bidet use step (S150), an anal washing performance step (S151 to S154) for performing an irrigation function for washing the anus of the human body according to the user's selection in the same manner as a normal bidet, and / or a female local A bidet performing step (S151 ′, S152 ′, S153, S154) for performing a bidet function for cleaning the screen may be included.

  That is, when the user selects the anal cleaning function (S151), the nozzle for performing the anal cleaning function is extended to a position corresponding to the human body, and the raw water is jetted to perform the anal cleaning function (S152). When the user presses the stop button (stop key) or the injection time elapses for a preset time (S153), the injection of the raw water is finished and the nozzle for performing the anal cleaning function returns to the original position. (S154).

  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 raw water is jetted. When the function is performed (S152 ′) and the user presses the stop button (stop key) or the injection time elapses for a preset time (S153), the injection of the raw water ends and the nozzle for performing the bidet function Returns to the original position (S154).

  As described above, the bidet use step (S150) may include a bidet nozzle and an anus cleaning nozzle that perform the respective functions as the injection nozzle 151 to perform the bidet function and the anal cleaning function, that is, two nozzles. The configuration of the nozzle 151 is not limited to this, and the anal cleaning performance stage (S151 to S154) and the bidet performance stage (S151 ′, S152 ′, S153, and S154) may be performed with one injection nozzle 151. That is, the nozzle unit 150 includes only one injection nozzle 151, and the movement of the injection nozzle 151 is adjusted by driving the nozzle driving unit 160 that moves the nozzle 150 in the front-rear direction. It can also be configured to do.

  As described above, when only one injection nozzle 151 is provided, the configuration of the nozzle unit 150 is simpler than the case where two injection nozzles 151 are provided, as described in the self-powered bidet 100 illustrated in FIG. Since only one injection nozzle 151 is moved, there is an advantage that the control of the nozzle driving unit 160 is easy.

  Meanwhile, the anal cleaning function performing step (S152) and the bidet function performing step (S152 ') may further include a flow rate selecting step of selecting a flow rate or water pressure to be injected in the same manner as a normal bidet. At this time, as described with reference to FIG. 6, the self-powered bidet 100 shown in FIG. 1 serves as the flow rate adjusting valve 144 for adjusting the flow rate, and the first flow path 145 a that is always open and the power application. In the case of using the latch valve including the second flow path 145b that is opened by the flow rate, the flow rate can be adjusted through simple ON / OFF of the latch valve, so that there is an advantage that power consumption can be greatly reduced.

  Meanwhile, the self-powered bidet control method (S100) according to an aspect of the present invention may be performed between the voltage check stage (S130) and the bidet use stage (S150), or the use detection stage (S110) and the bidet use stage (S150). A nozzle cleaning step (S140) of supplying raw water to the cleaning nozzle 152 to clean the spray nozzle 151 may be further included. Thus, when performing a nozzle washing | cleaning step (S140), before a user uses the injection nozzle 151, raw | natural water is injected in the state in which the injection nozzle 151 was contaminated by wash | cleaning the injection nozzle 151. In this process, the raw water is discharged during the nozzle cleaning process, so that power can be additionally generated through the power generator 120, thereby increasing the voltage of the charging unit 130. Become.

  Unlike this, although not specifically shown in FIG. 7, the self-powered bidet control method (S100) according to one aspect of the present invention is already in the power generation stage (S133) in the voltage check stage (S130). In the case where the process is performed, the standby process (S145) may be performed immediately without passing through the nozzle cleaning process (S140). That is, when power generation is performed through the cleaning nozzle 152 in the power generation stage (S133), the nozzle cleaning stage (S140) may not be performed because the spray nozzle 151 has already been cleaned.

  At the same time, after the bidet use step (S150), the nozzle cleaning step (S160) may be performed in which raw water is supplied to the cleaning nozzle 152 to clean the spray nozzle 151. As described above, when performing the nozzle cleaning step (S160), it is possible to maintain the spray nozzle 151 in a contaminated state by cleaning contaminants remaining on the spray nozzle 151 after the user's stool. Since the raw water is discharged in such a nozzle cleaning process, it is possible to additionally generate power through the generator 120, thereby increasing the voltage of the charging unit 130.

  The self-powered bidet control method (S100) according to one aspect of the present invention is such that the user terminates the use of the bidet through the sensor S, such as when the user leaves the toilet seat or leaves the bidet. A use end detection step (S170) for detecting the power supply, and a power cut-off step (S180) for cutting off the power supply from the charging unit 130 when a preset standby time elapses after the use end detection step (S170). Can be included.

  Although not specifically shown, even when the user leaves the toilet seat without using the bidet function or the anal washing function during the standby stage (S145), the use end detection stage (S170) and the power shutdown stage (S180) ) Can be done.

  As described above, after the user finishes using the bidet (for example, when leaving the toilet seat), various electrical components such as various valves 143, 144, 147, nozzle drive units are discharged from the charging unit 130 after a certain period of time has elapsed. The power consumption can be minimized by shutting off the power supply to the display 160 (not shown).

  At this time, after the user finishes using the bidet, it is preferable to completely cut off the power supply from the charging unit 130 to the electrical component in order to minimize the consumed power. However, it receives signals from the sensor S and the sensor S in order to sense through the sensor S that the user intends to use the bidet, such as sitting on the toilet seat, approaching the bidet, or using the remote control. In addition, a part of the configuration of the control unit C that re-supplys power to various electrical components may be configured such that a minimum power supply from the charging unit 130 is maintained.

  When the power is shut down in this way, when the user senses that the user wants to use the bidet in the above-described use sensing step (S110), the user can use the bidet and at the same time, the charging unit necessary for using the bidet. In order to confirm the voltage, a power supply stage (S120) is performed in which the power supply is resumed from the charging unit 130 to the various electrical components and the control unit C.

  At this time, the sensing sensor S may be a capacitance sensor, an infrared sensor, or the like, but after the user leaves the toilet seat, the power from the charging unit 130 is completely shut off, and then the user again For use, it is preferable to use a contact-type sensor such as a microswitch so that switching is performed automatically when sitting on a toilet seat or pressing a switch. As described above, when the microswitch is used, the power supply from the charging unit 130 to the various electrical components and the control unit C can be completely cut off at the power cut-off stage (S180). If it is made, the power supply from the charging unit 130 can be automatically resumed, so that power consumption when the bidet is not used can be eliminated.

  Next, referring 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 according to another embodiment of the present invention will be described. I will explain.

  The self-powered bidet control method (S100) illustrated in FIG. 9 is similar to the self-powered bidet control method (S100) illustrated in FIG. 7, as illustrated in FIG. 1, FIG. 4, and FIG. 5. FIG. 2, FIG. 4, and FIG. 5, which include a section 130, a nozzle section 150, and a nozzle flow path section 140. As described above, the generator 120, the charging unit 130, the nozzle unit 150, the nozzle channel unit 140, and the tank channel unit 190 are used to generate power through raw water flowing through the tank channel unit 190 and the nozzle channel unit 140. As shown in FIG. 3, the private power generation bidet 100 includes a generator 120, a charging unit 130, a nozzle unit 150, a nozzle channel unit 140, and a water channel unit 190 ′, and a water channel unit 90 'and a method for controlling the self-generating bidet 100 that power generation is performed in the generator 120 through the raw water flowing in the nozzle passage part 140.

  Specifically, the self-powered bidet control method (S100) illustrated in FIG. 9 is similar to the self-powered bidet control method (S100) illustrated in FIG. And a use sensing step (S110), and if it is sensed that the user intends to use a bidet, whether the voltage of the charging unit charged in the charging unit 130 is lower than a preset required charging voltage. If the voltage of the charging unit is lower than the required voltage, the voltage check stage (S130) for generating power through the generator 120 to charge the charging unit 130, and the nozzle unit 150 according to the user's function selection. A bidet use stage (S150) for supplying and injecting raw water, and further comparing the power generation capacity generated by the generator 120 with a preset reference value to determine whether or not private power generation is possible Configured to include a capability possibility determination step (S190).

  That is, the private power generation bidet control method (S100) illustrated in FIG. 9 further includes a private power generation possibility determination step (S190), except that the private power generation bidet control method (S100) illustrated in FIG. S100) is the same as or similar to S100), and therefore the description of the same or similar content is omitted to avoid unnecessary duplication, and only the difference is described.

  In the step of determining whether or not self-power generation is possible (S190), the power generation capacity generated by the generator 120 is compared with a reference value, and the self-power generation bidet 100 is installed in a place where self-power generation is possible (for example, a region where water pressure is high). This is a stage in which it is determined whether or not it is in a situation where private power generation is not efficiently performed due to fluctuations in water pressure, performance deterioration of the charging unit 130, or the like.

  In the case of the private power generation bidet 100 that generates power through the flow rate flowing in the flow channel inside the bidet, the power generation amount is very small, so it is necessary to minimize the amount of electricity used in the bidet, and the power generation capacity through the generator 120 Must be larger than the amount of electricity used by the bidet.

  Therefore, in order to determine whether the power generation capacity is sufficient as compared with the amount of electricity used, it is possible to perform a private power generation possibility determination step (S190) at a stage after the use detection stage (S110).

  Such an in-house power generation possibility determination step (S190) can be performed as one process at any stage between the use detection stage (S110) and the power-off stage (S180). When the determination step (S190) ends, the process returns to the original step (S195), and the subsequent steps are performed.

  As shown in FIG. 10, the in-house power generation possibility determination step (S 190) includes a power generation execution step (S 191) in which raw water is introduced into the generator 120 to generate power, and an impeller in the power generation process of the generator 120. A signal comparing the generator frequency with a preset reference frequency (S192), and if the generator frequency is greater than the reference frequency, the power generation capacity is sufficient and the private power It may be determined that the state is possible (S193), and if not, it may be determined that there is a problem with private power generation and displayed (S194). At this time, the reference frequency can be set in consideration of various factors such as the amount of electricity used expected in normal bidet use and the power generation capacity generated per revolution of the impeller.

  That is, in the determination step of whether or not private power generation is possible according to an embodiment of the present invention (S190), the raw water is supplied to the generator 120 to drive the generator 120, and the generator is generated by the rotation speed of the impeller due to the pressure of the raw water. The frequency is compared with the reference frequency, and it is determined whether or not the pressure of the raw water is sufficient to allow private power generation.

  At this time, in the power generation stage (S191), since the raw water is discharged through the nozzle unit 150 after the raw water is introduced into the generator 120, the generator 120 is included in the stage illustrated in FIG. It is more preferable to use a stage in which raw water is supplied. For example, in the power generation feasible stage (S191), the nozzle cleaning stage (S140) can be used as indicated by “B” in FIG. 9, and the nozzle cleaning stage as indicated by “D” in FIG. (S160) can also be used. However, the power generation performance step (S191) is not limited to this, and may be performed as a separate step after the voltage check step (S130) as indicated by “A” in FIG. As indicated by “C”, it may be performed as a separate step after the bidet use step (S150).

  On the other hand, since the private power generation possibility determination step (S190) is a step for determining whether or not the raw water pressure is suitable for use of the private power generation bidet, the power supply is performed after the use detection step (S110). It is sufficient to carry out only once during the shut-off phase (S180). In addition, it is not always necessary to perform the private power generation feasibility determination step (S190) every time a bidet is used, such as initial setting of the bidet, manual selection by the user, and a fixed period. Can be performed in various forms.

  Thus, according to one embodiment of the present invention, it is determined whether the power generation capacity is sufficient for bidet use by performing the private power generation possibility determination step (S190), and the power generation capacity is insufficient. By displaying this, there is an effect that it is possible to confirm whether or not the private power generation bidet 100 can be stably used.

  While the invention has been illustrated and described with reference to specific embodiments, those skilled in the art will recognize that the invention is within the spirit and scope of the invention as defined by the appended claims. Can be modified and changed in various ways.
