Description

Fluid systems for bidets

technical field

The invention relates to a flow system for a bidet, in particular to a flow system for a bidet capable of sending raw water at room temperature into a sterilizer.

Background technique

Generally speaking, a washing machine, usually called a bidet, is a device that is integrally installed on a toilet seat, and uses washing water sprayed through a nozzle to wash the user's anus and a woman's vulva without using toilet paper after going to the toilet . Also have, nozzle is made up of the water flow nozzle that is used for washing user's anus and the bidet nozzle that is used for cleaning women's vulva. In this case, the bidet may be provided with a nozzle cleaning water discharge unit for cleaning the water flow nozzle and/or the bidet nozzle.

Also, the bidet has a flow path changing valve installed therein for changing a flow path to selectively supply wash water or nozzle cleaning water to the water flow nozzle, the bidet nozzle, and the nozzle cleaning water discharge unit. Therefore, washing water or nozzle cleaning water is distributed and flows through the respective nozzles in accordance with the switching operation of the flow path changing valve.

FIG. 1 is a schematic diagram showing the configuration of a conventional flow system for a bidet.

Referring to FIG. 1 , a conventional flow system 10 for a bidet includes a water input valve 11 , a hot water tank 12 , a channel changing valve 13 , a sterilizer 17 and a nozzle unit 18 . Water for the bidet flows through the water input valve 11, and is stored in the hot water tank 12 and heated to a suitable temperature. Therefore, when the user uses the bidet, the hot water stored in the hot water tank 12 is sent out through the nozzle unit 18 .

Also, the flow path change valve 13 is connected to the hot water tank 12 to feed the hot water sent from the hot water tank 12 to the water flow nozzle or the bidet nozzle installed in the nozzle unit 18, or to feed the hot water through the sterilizer 17. Water is fed to the nozzle cleaning water discharge unit.

For example, when the user selects the cleaning option, the flow path of the flow path changing valve 13 changes to spray hot water, and the hot water is sent from the hot water tank 12 through the water flow nozzle through the water flow nozzle flow path 15, and when the user chooses to clean himself, When the water heater option is used, the flow path of the flow path changing valve 13 changes to spray hot water, and the hot water is sent from the hot water tank 12 through the bidet nozzle flow path 16 through the bidet nozzle.

At this time, when the sensor used to detect the user's sitting behavior detects that the user is sitting on the bidet, the bidet sends hot water to the nozzle cleaning water discharge unit through the nozzle cleaning flow channel 14 to clean the water. body nozzle and/or water jet. In this case, the sterilizer 17 for generating nozzle cleaning water containing antibacterial and/or sterilizing substances is provided in the nozzle cleaning flow path 14 to send the nozzle cleaning water to the nozzle cleaning water discharge unit, thereby, Disinfect and clean the water jets and/or bidet nozzles.

For example, the sanitizer 17 may be configured such that it electrolyzes incoming raw water to produce nozzle cleaning water containing antibacterial and/or sanitizing substances. The nozzle cleaning water thus generated in the sterilizer 17 is sent to the nozzle cleaning water discharge unit to aseptically sterilize the water flow nozzle and the bidet nozzle.

Different from the above configuration, when the user selects the nozzle cleaning option, hot water can be sent to the sterilizer 17 through the nozzle cleaning channel 14, and the nozzle cleaning water generated in the sterilizer 17 can be sent to the nozzle unit 18 to clean Water jet and bidet nozzle.

However, since the conventional flow system 10 for a bidet has the flow path changing valve 13 installed between the hot water tank 12 and the nozzle unit 18, hot water is always sent to the water flow nozzle, bidet nozzle and a nozzle cleaning water discharge unit, all of which are provided in the nozzle unit 18. Therefore, hot water is used even when the water jet nozzle and the bidet nozzle are cleaned, resulting in waste of hot water.

As a result, even when there is no need to supply hot water, since the hot water is used, the energy used to heat the raw water is wasted. Since the design of the storage capacity of the hot water tank 12 must consider the amount of hot water that is unnecessary to be wasted, so , it is unnecessarily required to increase the storage capacity of the hot water tank 12.

Also, the conventional flow system 10 for a bidet has a problem in that since hot water is fed to the sterilizer 17, the efficiency of electrolysis is more reduced than when cold water is fed to the sterilizer 17, which causes the nozzle Loss of cleaning water disinfection efficiency. That is, a problem with the conventional flow system 10 for bidets is that, since hot water is used instead of room temperature water (cold water) used as raw water for generating nozzle cleaning water containing antibacterial and/or sterilizing substances, the same The nozzle cleaning water produced has a much reduced sanitizing activity than when room temperature water is used to generate the nozzle cleaning water. Consequently, the cleaning properties (ie, disinfection activity) of the nozzles are reduced.

In the case of the conventional flow system 10 for the bidet, since the flow channel changing valve 13 is installed at the front end of the hot water tank 12, the flow of water previously flowing into the hot water tank 12 through the water input valve 11 is affected by the flow channel. Change the control of valve 13. As a result, since a negative pressure is formed in the hot water tank 12, it is necessary to strengthen the hot water tank 12 so that the hot water tank 12 can withstand the negative pressure, which leads to an increase in manufacturing cost. Also have, because the negative pressure in the hot water tank 12 causes the leak of water, can cause the accident of electric shock.

The raw water supply unit 310 is provided with a valve to control the supply of raw water, and the raw water sent from the raw water supply unit 310 flows into the flow channel changing valve 320 through the raw water input channel 315 . Then, the raw water at room temperature flowing out of the raw water supply unit 310 flows into the flow channel changing valve 320 .

Also, the flow path changing valve 320 changes the flow path so that the incoming water can flow through at least one flow path among the plurality of flow paths provided on the outlet side of the flow path changing valve 320 . That is, the flow path changing valve 320 has a plurality of outlets (not shown), and discharges the introduced raw water through at least one of the plurality of outlets.

Then, the sterilizer 340 is connected to the outlet side of the flow path changing valve 320 through the nozzle cleaning flow path 325 , and thus, raw water at room temperature is sent to the sterilizer 340 from the flow path changing valve 320 . The sterilizer 340 generates nozzle cleaning water containing antibacterial and/or sterilizing substances from raw water, and the nozzle cleaning water is fed to the nozzle cleaning water discharge unit 381 through the nozzle cleaning water supply flow path 345, so that the raw water can have sterilizing activity and be used The nozzle cleaning water cleans at least one nozzle installed in the nozzle unit 380 .

When the sterilizer 340 can be used to generate nozzle cleaning water containing antibacterial and/or sterilizing substances, there are no particular limitations on the type and structure of the sterilizer 340 . For example, the sterilizer 340 can be configured such that it can generate various mixed oxidizing agents with sanitizing activity, such as hypochlorous acid (HOCl), hypochlorite ion (OCl ⁻ ), chlorine gas (C1 ₂ ), and other antimicrobial and/or or disinfecting ions or free radicals. Here, mixed oxidants can be produced by electrolysis of water passing between electrodes with different polarities. In this case, the mixed oxidizing agent acts as an antimicrobial and/or disinfectant substance. At this point, the sterilizer 340 may be configured as a device that discharges a constant amount of an antibacterial and/or sterilizing substance such as iodine or silver oxide.

Also, the heating member 360 is connected to the outlet side of the flow passage changing valve 320 through the heating raw water supply flow passage 330 , and the room temperature raw water discharged from the flow passage changing valve 320 is fed to the heating member 360 . Then, the outlet side of the heating member 360 is connected to the nozzle unit 380 through the hot water supply flow path 365 . Such a heating member 360 may consist of a hot water tank for heating and storing water flowing therein, but the present invention is not particularly limited thereto. Also, the heating member 360 may be constituted by an instant water heater that rapidly heats incoming water while the water flows therethrough. Therefore, when the user selects a washing option or a bidet option, hot water heated in the heating member 360 is sprayed through the nozzle unit 380 .

Therefore, since raw water at room temperature flows into the sterilizer 340 , waste of energy consumed for heating water unnecessarily can be prevented, and therefore, the hot water storage capacity in the heating member 360 can be reduced.

That is, since the hot water is fed to the sterilizer in the conventional flow system for the bidet as shown in FIG. box storage capacity. However, as shown in FIG. 2 , a flow system 300 for a bidet according to an exemplary embodiment of the present invention may be adapted to solve these problems in the prior art because raw water at room temperature flows into the sterilizer 340 .

Also, since the flow system 300 for a bidet according to an exemplary embodiment of the present invention can directly feed raw water at room temperature to the sterilizer 340, the sterilizer 340 can generate nozzle cleaning water with enhanced sterilizing activity. Therefore, it is possible to improve the cleaning characteristics (ie, disinfection activity) of the nozzle.

FIG. 3 is a schematic diagram showing the configuration of a flow system for a bidet according to another exemplary embodiment of the present invention. Referring to FIG. 3 , a flow system 400 for a bidet includes a flow path changing valve 100 , a sterilizer 440 , a heating member 460 and a nozzle unit 480 .

Raw water fed from the raw water supply unit 410 flows into the flow path changing valve 100 through the raw water input flow path 415 and the raw water inlet 111a. Then, raw water at room temperature flows from the raw water supply unit 410 into the flow path changing valve 100 .

Also, the flow path changing valve 100 changes the flow path so that the incoming water can flow through at least one flow path among the plurality of flow paths installed on the outlet side of the flow path changing valve 100 . That is, the flow path changing valve 100 is provided with a plurality of inlets 111a and 121a, and a plurality of outlets 122a, 123a, 125a, and 126a. Here, the introduced raw water is discharged from the respective inlets 111a and 121a to at least one of the plurality of outlets 122a, 123a, 125a, and 126a.

In addition, the sterilizer 440 is connected to the nozzle cleaning water outlet 122 a of the flow path changing valve 100 through the nozzle cleaning flow path 425 . Accordingly, room temperature raw water is fed from the flow path changing valve 100 to the sterilizer 440 . The sterilizer 440 generates nozzle cleaning water containing an antibacterial and/or sterilizing substance from the raw water fed to the nozzle cleaning water discharge unit 481, so that the raw water can have a sterilizing activity, and is used to clean the nozzles installed in the nozzle unit 480. at least one of the nozzles. As the sterilizer 440, a device that generates water with sterilizing activity by electrolysis can be used.

Also, the heating member 460 is connected to the raw water outlet 123a of the channel changing valve 100 through the heating raw water supply channel 430, and the outlet side of the heating member 460 is connected to the channel changing valve 100 through the hot water supply channel 450. Hot water inlet 121a. As a result, the raw water at room temperature discharged from the raw water outlet 123a of the flow path changing valve 100 is fed into and heated in the heating member 460, and the hot water heated in the heating member 460 is heated through the hot water inlet 121a. It is fed into the channel changing valve 100 again. Such a heating member 460 may consist of a hot water tank for heating and storing water flowing therein, but the present invention is not particularly limited thereto. Also, the heating member 460 may consist of an instant water heater that rapidly heats incoming water as the water flows therethrough. Therefore, when the user selects the washing option or the bidet option, the hot water heated in the heating member 460 flows into the channel changing valve 100 again, and is sprayed out through the nozzle unit 480 .

Also, the nozzle unit 480 may be provided with a water flow nozzle 482 for washing the user's anus, a bidet nozzle 483 for washing the vulva of a woman, and the like. Here, a nozzle cleaning water discharge unit 481 for the washing water flow nozzle 482 and/or the bidet nozzle 483 may be further installed in the nozzle unit 480 .

If the nozzle unit 480 is composed of a plurality of nozzles as described above, it is necessary to feed the hot water heated in the heating member 460 and then flow into the channel changing valve 100 to feed the hot water to one of the nozzles installed in the nozzle unit 480. nozzle.

For this purpose, the flow path changing valve 100 changes the flow path so that the hot water heated in the heating member 460 and reflowed into the flow path changing valve 100 is selectively passed through the water flow nozzle flow path 465 and the bidet nozzle flow path. One of the channels 470 feeds either the water jet 482 or the bidet nozzle 483 .

The channel changing valve 100 is arranged in the flow system 400 for the bidet as shown in FIG. Room temperature raw water is fed into one of the sterilizer 440 and the heating member 460 .

That is, when hot water is used in the nozzle unit 480 , the flow path changing valve 100 changes the flow path so that raw water can flow into the heating member 460 only. Then, the hot water discharged from the heating member 460 is divided again in the channel change valve 100 . In this case, the divided hot water is fed and sprayed toward the water flow nozzle 482 or the bidet nozzle 483 through one of the water flow nozzle flow path 465 and the bidet nozzle flow path 470 . Also, if the water flow nozzle 482 or the bidet nozzle 483 must be cleaned during disinfection, the flow path change valve 100 changes the flow path so that the raw water at room temperature can only flow into the sterilizer 440 . In this case, the nozzle cleaning water generated in the sterilizer 440 is sent to the nozzle cleaning water discharge unit 481 through the nozzle cleaning water supply flow path 425, thereby cleaning the nozzles.

The operation of the flow system 400 for the bidet shown in FIG. 3 will now be described in detail.

When water is needed to perform the nozzle cleaning option or the bidet/rinsing option, the raw water supply unit 410 is turned on, and room temperature raw water sent from the raw water supply unit 410 flows into the channel change valve 100 through the raw water inlet 111a.

For this purpose, the rotating disc 220 may include: selection holes 221, 222 and 223 formed therethrough so that the raw water input part 111 can be selectively connected to the communication holes 212, 213', 213a, 214' and 214a. One, these holes communicate with the heating raw water supply unit 123 and the nozzle cleaning water supply unit 122 respectively; to one of the communication holes 125a and 126a, which communicate with the wash water supply unit 125 and the bidet water supply unit 126, respectively.

The guide groove 226 may include a central groove 224 and an extension groove 225, the central groove 224 is arranged on the communication hole 211 communicating with the hot water input part 121; The communication holes 125a and 126a communicate with the wash water supply unit 125 and the bidet water supply unit 126, respectively.

According to the above-mentioned structure of the fixed disk 210 fixedly installed in the second housing 120 and the rotating disk 220 rotating on the fixed disk 210, by selectively connecting the communication hole 212 of the fixed disk 210 with the selection hole 221 of the rotating disk 220 and 222 , the nozzle cleaning water supply unit 122 can be communicated with the raw water input part 111 . Accordingly, the nozzle cleaning water supply unit 122 receives water flowing from the raw water input part 111, and discharges the received water through the nozzle cleaning water outlet 122a.

Also, by selectively connecting the communication holes 213', 213a, 214' and 214a of the fixed disk 210 with the selection hole 223 of the rotating disk 220, the heating raw water supply unit 123 can communicate with the raw water input part 111. Accordingly, the heating raw water supply unit 123 receives water flowing from the raw water input part 111, and discharges the received water through the raw water outlet 123a.

In addition, the wash water supply unit 125 and the bidet water supply unit 126 communicate with the hot water input part 121 by selectively connecting the communication holes 215 a and 216 a of the fixed disk 210 with the selection holes 221 and 222 of the rotary disk 220 . Accordingly, the wash water supply unit 125 and the bidet water supply unit 126 receive water flowing out from the hot water input part 121 and discharge the received water through the wash water supply hole 125a and the bidet water supply hole 126a.

That is, the hot water flowing into the hot water input part 121 is fed to the water flow nozzle 482 through the wash water supply hole 125a and the wash water supply line 465, and is sprayed out through the water flow nozzle 482, or passed through the bidet water supply hole 126a and the bidet water supply hole 126a and the water flow nozzle 482. The bidet water supply line 470 feeds into the bidet nozzle 483 and is sprayed out through the bidet nozzle 483 .

When the flow path change valve 100 as shown in FIGS. 4 to 8 is used in a bidet as described above, it is advantageous to simplify the complicated flow path, thus reducing the number of required valves.

Referring to FIG. 3 and FIGS. 9 to 12 , the operation of the flow path changing valve 100 will be described in detail.

FIG. 9 shows the position of the rotary disk 220 at the start of the operation of the flow path changing valve 100 . As shown in FIG. 9, at the beginning, the selection holes 221, 222 and 223 or the guide grooves 226 formed in the rotating disk 220 are not connected to the communication holes 211, 212, 213', 213a, 214 formed in the fixed disk 210. ', 214a, 215a and 216a. As a result, since the flow path is closed, water does not flow at this time.

When the user uses the bidet, for example, selects the cleaning option in this case, the rotating disk 220 is driven by the motor 150 to rotate counterclockwise, as shown in FIG. 10 , and thus, the nozzle cleaning option is executed. That is, the communication hole 212 of the fixed disk 210 is matched with the selection hole 222 of the rotating disk 220 to allow raw water to flow from the raw water input part 111 formed in the first housing 110 on the rotating disk 220 to the nozzle cleaning water supply unit. 122. In this case, the raw water flowing into the nozzle cleaning water supply unit 122 is fed to the nozzle cleaning water discharge unit 481 through the nozzle cleaning water outlet 122a and the sterilizer 440 to sterilize and clean the water flow nozzle 482 and/or the bidet nozzle 483. cleaning. At this time, the other selection holes 221 and 223 and the guide groove 226 of the rotating disk 220 are closed by the upper surface of the fixed disk 210, as shown in FIG. 10 . Therefore, no flow path is formed other than the nozzle cleaning water supply flow path.

Then, the rotating disc 220 is further rotated counterclockwise so as to feed water to the water flow nozzle 482 as shown in FIG. 11 . As a result, the selection hole 223 of the rotating disk 220 communicates with the communication hole 214' of the fixed disk 210 and the communication hole 214a connected to the groove 214, and the guide groove 226 of the rotating disk 220 is connected to the communication hole 211, which is connected to the heat sink 211. The water input part 121 communicates with the communication hole 215 a connected to the groove 215 .

In this case, since the communication hole 214' and/or the communication hole 214a communicate with the selection hole 223, the raw water flowing into the raw water input part 111 moves to the heating raw water supply unit 123, and then flows into the heating raw water supply unit 123 through the raw water outlet 123a. Member 460. Then, the introduced raw water is heated within the heating member 460, and flows into the hot water input part 121 again through the hot water outlet 121a. Then, the hot water that sequentially flows through the communication hole 211 of the fixed disk 210, the center groove 224 of the guide groove 226, and the extension groove 225 (all of which are formed in the lower surface of the rotating disk 220) passes through the groove connected to the fixed disk 210. The communication hole 215 a of 215 flows into the washing water supply unit 125 , and is fed to the water flow nozzle 482 through the washing water supply hole 125 a to be sprayed out through the water flow nozzle 482 .

In this case, hot water heated in the heating member 460 flows into the hot water input part 121 just after the raw water flowing out of the raw water input part 111 is transferred to the heating raw water supply unit 123 and discharged toward the heating member 460 , and then, is fed to the water flow nozzle 482 through the washing water supply unit 125 .

At this time, in order to increase the amount of sprayed washing water as the rotating disk 220 rotates, the groove 214 connected to the communication hole 214a may be formed such that the width of the groove 214 increases from one end to the other.

As shown in FIG. 12, when the groove 214 reaches the widest width as the rotating disk 220 further rotates, the injection amount of the washing water reaches the maximum limit. Therefore, by adjusting the rotational speed (rotation angle) of the rotating disk 220, the water volume and density of sprayed washing water can be adjusted.

When the rotating disk 220 is rotated clockwise after the cleaning option, the rotating disk 220 passes the position of the nozzle cleaning option as shown in FIG. 10 , but returns to the original position as shown in FIG. 9 .

At this time, the rotating disk 220 of FIG. 9 rotates clockwise from its initial position, so as to execute the selection of the bidet. When the rotating disk 220 is rotated clockwise, the specific operation of the rotating disk 220 is basically equivalent to the cleaning option, except that the communication hole 212 of the fixed disk 210 is matched with the selection hole 221 of the rotating disk 220 to perform the nozzle cleaning option . Therefore, for the sake of brevity, the specific operation of rotating the disk 220 is omitted.
