The present invention relates to a bidet having a cleaning nozzle, and more particularly, to a bidet configured to sterilize and disinfect the cleaning nozzle by disinfecting water.

In general, our toilet culture relies on toilet paper for most of its treatment after stool.

However, since the feces are excreted around more than a thousand fine lines, it is virtually impossible to completely remove dirt remaining between the fine lines, no matter how clean the post-treatment using toilet paper. There are frequent factors such as anal diseases such as hemorrhoids, female diseases such as vaginitis, and male diseases such as prostate.

Therefore, in recent years, as a means to solve the post-stool post-treatment process cleanly and hygienically, the cleaning water supplied from the water supply line is used to clean the area around the anus using a nozzle, and the cleaned anal part may be dried by hot air. Bidet is widely developed and distributed to each household.

Hereinafter, a conventional bidet will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a conventional bidet.

As shown in FIG. 1, a conventional bidet includes a nozzle part 11 to allow the washing water (tap water) to be sprayed to the anal side of the user, and a water supply line connected to the tap water so that the washing water can be supplied to the nozzle part 11. It is provided with a body portion 12 is provided, the body portion 12 has a general configuration that is installed on the toilet seat 14 is connected to the seat plate 13, the user can sit and see the toilet.

In addition, according to the type of bidet is equipped with a reservoir for supplying water in the bidet itself in the case of the high-end type is to produce hot water in the bidet itself to supply the washing water.

The conventional bidet as described above has the advantage of cleaning the user's anus or vagina, but before or after using the nozzle because there is no separate device for cleaning the next user is unclean state There was a cumbersome and inconvenient problem that should be used after or using a separate cleaning tool for cleaning.

In order to solve this problem, a bidet for cleaning the nozzle has been designed.

2 is a block diagram showing the configuration of a bidet having a conventional nozzle cleaning function.

The bidet shown in FIG. 2 filters the water supplied through the water supply line 20 to the filter 30, and then temporarily stores the water in the storage container 40 and supplies it to the washing nozzle 11 according to the user's selection. It is configured to clean the vagina, and this basic operation is the same as the bidet shown in FIG.

However, the bidet shown in FIG. 2 is to clean and use the cleaning nozzle 11 before or after using the cleaning nozzle 11 so that it can be used hygienically and cleanly. The cleaning nozzle 60 which wash | cleans the cleaning nozzle 11 by spraying toward 11 is added.

The cleaning nozzle 11 and the cleaning nozzle 60 are connected to a pump 50 for supplying the water of the reservoir 40, and the pump 50 cleans the water stored in the reservoir 40 according to a user's selection. 11) and the washing nozzle (60). That is, when the user selects the bidet function, the pump 50 supplies water to the washing nozzle 11 to clean the anus or vagina of the user, and when the user selects the washing function, the pump 50 supplies the washing nozzle 60. ) So that the cleaning nozzle 11 is washed with water. One end of the washing nozzle 60 is connected to the pump 50 and a connection hose, and when water is introduced into the pump 50 through the connection hose, water is sprayed to the washing nozzle 11 using nozzle holes formed at the other end. To wash the cleaning nozzle (11).

The cleaning nozzle 60 has a height so as to be spaced apart from the cleaning nozzle 11 upward by a predetermined interval so as to enable such cleaning, and is positioned to have a lengthwise direction parallel to the cleaning nozzle 11.

However, the conventional bidet structured as described above has a function of simply washing the washing nozzle 11 by using the tap water filtered by the filter 30, so that the washing nozzle 11 cannot be sterilized. There is this. In addition, if the time for cleaning the washing nozzle 11 is too long, it is inconvenient to use, so that the water sprayed through the washing nozzle 60 is in contact with the washing nozzle 11 is set to about 3 to 5 seconds, such a short There are many difficulties in completely cleaning the cleaning nozzle 11 in time. In particular, the cleaning nozzle 11 has a problem that it is difficult to maintain hygiene because it is a portion that is floating in the air rather than a portion that is submerged in water.

In addition, since the conventional bidet uses tap water for washing the washing nozzle 11, there is a problem that the washing nozzle 11 may be secondaryly infected by bacteria or various pathogens contained in the tap water.

In order to solve such a problem, a method of sterilizing the tap water using electrolysis and then sterilizing the washing nozzle 11 with sterilized water has been proposed. However, TDS (Total Dissolved), such as tap water or ground water, has been proposed. Since the scale is generated when the solid is treated with high water, various problems such as clogging of the flow paths of the pump 50 and the nozzles 11 and 60 located at the rear end are caused by this scale. have.

In order to prevent the discharge of the scale may be provided with a sieve for filtering the scale additionally, if the sieve is provided in this way, the configuration for the sieve combination must be added, not only the internal configuration is complicated, but the flow rate may be reduced, When used for a long time there is a problem that the strainer may be blocked by the scale.

The present invention has been proposed to solve the above problems, and can not only clean the cleaning nozzle, but also sterilization and disinfection, and can prevent the flow path from clogging by filtering the scale included in the sterilization water without a separate filter. The purpose is to provide a bidet.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of a bidet having a cleaning nozzle sterilization function according to the present invention.

3 is a block diagram of a bidet according to the present invention.

As shown in FIG. 3, the bidet according to the present invention includes a water supply line 20 for delivering water supplied from the outside, a filter 100 for receiving water from the water supply line 20, and filtering the water. Washing water tank 310 for storing the water filtered by the 100 and the washing water tank 310 by the operation of the washing water pump 410 receives the washing water through the washing water injection port 512 The cleaning nozzle 510 for spraying the water, the sterilization apparatus 200 for sterilizing water supplied from the water supply line 20, and the sterilization water tank 320 for storing the water sterilized by the sterilization apparatus 200. And, by the operation of the sterilization water pump 420 is supplied with the water of the sterilization water tank 320 sterilization nozzle 520 for injecting sterilization water to the cleaning nozzle 510 through the sterilization water injection port 522 It is configured to include.

The sterilization apparatus 200 is configured to sterilize bacteria or contaminants contained in the water by using an electrolysis method, unlike the filter 100 for filtering out foreign matter or suspended matter contained in the water. As the electrolysis reaction proceeds, the reaction of direct oxidization of bacteria and microorganisms in water, as well as various oxidative mixtures such as chlorine, ozone, OH radicals and oxygen radicals, simultaneously indirect oxidation and sterilization Thus, the cleaning nozzle 510 is sterilized as well as cleaned, so there is no fear of contamination. Detailed structure and operation principle of such a sterilization apparatus 200 will be described in detail with reference to the separate drawings below.

The user operates the sterilization nozzle 520 before or after using the cleaning nozzle 510 to clean the cleaning nozzle 510, whereby the cleaning nozzle 510 is formed by external bacteria or bacteria contained in the supplied water. You can use bidet with confidence without fear of contamination.

At this time, the water to be supplied is filtered through a filter and stored in the washing water tank 310, and then supplied to the washing nozzle 510 using the washing water pump 410, and to wash the user's anus and vagina Since the structure and function of the cleaning nozzle 510 for spraying water are the same as the structure and function of the components applied to the conventional bidet, a detailed description thereof will be omitted.

Figure 4 is an exploded perspective view of the sterilizing apparatus included in the bidet according to the present invention, Figure 5 is an exploded perspective view showing the arrangement and coupling structure of the positive electrode plate and the negative electrode included in the bidet according to the present invention.

4 and 5, the sterilization apparatus applied to the present invention includes a housing 210 configured to allow fluid to flow through an inlet portion 211 formed at a lower side thereof and outflow through the outlet portion 212 formed at an upper side thereof. ), Electrolytic sterilization means 220 having an anode plate 221 and a cathode plate 222 which are alternately arranged so as to be spaced apart from each other by a predetermined interval, and the anode plate 221 and the cathode plate 222. Holder 230 for fixing the position, and the through hole 241a in the vertical direction is formed so that the water passing through the electrolytic sterilization means 220 toward the water outlet 212 passes through the through hole 241a A support plate 241 coupled between the 212 and the electrolytic sterilization means 220 and a pipe shape in which the hollow 242a is provided in the vertical direction are formed to cover the upper inlet of the through hole 241a. Including filtering means 240 having a discharge pipe 242 coupled to the upper surface of It is composed.

The housing 210 is configured such that water flowing into the body flows upward and discharges vertically, but the housing 210 applied to the present invention is not limited to the vertical flow upward as shown in the present embodiment. Can be changed to be inclined at an angle.

Electrolytic sterilization means 220 is for electrolyzing water located between the positive electrode plate 221 and the negative electrode plate 222 by applying a voltage to the positive electrode plate 221 and the negative electrode plate 222, respectively, the positive electrode plate 221 and the negative electrode plate The positive electrode plate 221 and the negative electrode plate 222 are arranged side by side in the longitudinal direction along the flow direction of the water so as to smoothly flow the water between the 222 and through the one side wall of the housing 210 to the outside of the housing 210. The exposed positive electrode terminal 221a and the negative electrode terminal 222a are formed, respectively. Therefore, there is an advantage that the wiring for applying power to the positive terminal 221a and the negative terminal 222a is simplified.

In addition, the positive electrode terminal 221a and the negative electrode terminal 222a are formed to have different vertical positions, and the housing 210 has a positive terminal hole 213 and a portion corresponding to the positive electrode terminal 221a and the negative electrode terminal 222a. Since the negative electrode terminal hole 214 is formed, the manufacturer can easily assemble the positive electrode plate 221 and the negative electrode plate 222 without fear of changing the coupling position of the positive electrode plate 221 and the negative electrode plate 222.

During the electrolysis reaction, bacteria and microorganisms contained in the water are directly oxidized and indirectly oxidized by various oxidative mixtures such as chlorine, ozone, OH radicals and oxygen radicals generated in the positive electrode plate 221. And sterilization proceed simultaneously. As described above, since the method and the effect of sterilization using electrolysis are the same as the method and effect of the above-mentioned conventional water treatment apparatus, detailed description thereof will be omitted.

In order to effectively generate the oxidizing mixture, a sufficient potential difference must be provided between the positive electrode plate 221 and the negative electrode plate 222. In this case, since the oxidation may proceed to the positive electrode plate 221 itself, the positive electrode plate 221 is made of platinum or It is preferred to be coated with a platinum based material. In this case, since the platinum-based metal is very expensive, the positive electrode plate 221 may be manufactured to make a plate of relatively inexpensive titanium and to coat with ruthenium, a platinum group having a sterilizing effect.

In this case, since the oxidative mixture is generated in the positive electrode plate 221, two or more positive electrode plates 221 are provided and a negative electrode plate 222 is provided between the positive electrode plates 221, respectively. In this embodiment, two negative electrode plates 222 are arranged between three positive electrode plates 221 to form a total of five electrode plates. However, the number of the positive electrode plates 221 and the negative electrode plates 222 is not limited thereto. Depending on the number can be applied.

In addition, the positive electrode plate 221 and the negative electrode plate 222 are arranged to have an interval of 0.5 mm or less so as to effectively generate an oxidizing mixture even when a low voltage is applied.

The holder 230 is coupled to the upper and lower ends of the positive electrode plate 221 and the negative electrode plate 222 so as to fix upper and lower ends of the positive electrode plate 221 and the negative electrode plate 222, respectively. The holder 230 has an opening 231 formed in a center portion thereof so that water can pass therethrough, and upper ends of the positive electrode plate 221 and the negative electrode plate 222 on the surface facing the positive electrode plate 221 and the negative electrode plate 222. A slot 232 is formed in which the lower end can be retracted.

The holder 230 is the outer end is coupled to the inner wall of the housing 210, the positive electrode plate 221 and the negative electrode plate 222 is coupled by the upper end and the lower end is coupled to be inserted into the slot 232 of the holder 230 Is fixed.

At this time, the holder 230 is not limited to the rectangular shape in which the opening 231 is formed in the center portion as in the present embodiment, and may be formed in a bar shape in which the side surface is coupled to the inner wall of the housing 210.

Filtering means 240 is a means for filtering the scale contained in the water past the electrolytic sterilization means 220, it is configured to filter the scale by using the flow pressure of the water and the weight of the scale. The supporting plate 241 and the discharge tube 242 may be integrally formed or may be combined after being separately manufactured as shown in FIG. 6.

Since the outer end of the support plate 241 is in close contact with the entire inner wall of the housing 210, the water and scale flowing through the electrolytic sterilization means 220 to the water outlet 212 are passed through the discharge pipe 242. . At this time, since the inner horizontal area of the discharge pipe 242, that is, the cross-sectional area of the hollow 242a is smaller than the horizontal cross-sectional area of the inside of the housing 210, the water is increased in speed while passing through the discharge pipe 242, the discharge pipe As soon as it exits 242, the speed is drastically reduced. Since the scale has a specific gravity higher than that of water, the scale does not reach the water outlet 212 after exiting from the discharge tube 242 and is accumulated on the upper surface of the support plate 241. In this way, if the scale leakage to the outside of the housing 210 is prevented, the system located at the rear end of the housing 210, that is, the pumps 410 and 420 or the nozzles 510 and 520 may be prevented from being blocked or damaged by the scale. There is an advantage.

In order to prevent the scale from leaking out of the housing 210, instead of installing the filtering means 240, a method of installing the filtering net in the water extraction unit 212 may be proposed, but if the filtering net is installed in the water extraction unit 212, The scale is re-introduced between the positive electrode plate 221 and the negative electrode plate 222 to hinder the efficiency of electrolysis, and also has a disadvantage in that maintenance and repair are cumbersome since the filter net needs to be cleaned and replaced periodically.

On the other hand, the filtering means 240 applied to the present invention is not only simple in configuration, but also prevents the phenomenon of the scale flowing back between the positive electrode plate 221 and the negative electrode plate 222 and the phenomenon of leaking out of the housing 210 at the same time. There is an advantage.

A detailed description of the process in which the scale exits from the discharge pipe 242 and is mounted on the upper surface of the support plate 241 will be described in detail with reference to FIG. 6.

6 is a cross-sectional view of a sterilizer included in the bidet according to the present invention.

As shown in FIG. 6, the water introduced into the housing 210 through the inlet part 211 is sterilized while passing between the positive electrode plate 221 and the negative electrode plate 222, and is disposed at the upper end of the filter 240. Will be moved to.

As the water passing through the electrolytic sterilization means 220 and the scale S flow into the hollow 242a of the discharge tube 242, the position head increases, but as the speed increases, the pressure head decreases. The water and the scale S are sucked into the discharge pipe 242. Water and scale (S) introduced into the discharge tube 242 is reduced both in the position head and the pressure head at the moment of exiting the discharge tube 242, so that the speed is sharply reduced, thereby increasing the force upward upward .

At this time, the scale S has a specific gravity, i.e., a mass per unit volume, larger than water, thereby further reducing the speed of rising upward due to its own weight and falling down without reaching the water extraction unit 212. Since the water and the scale S are continuously discharged to the discharge tube 242, the scale S falling downward is not loaded into the discharge tube 242 and is loaded on the upper surface of the support plate 241.

If the discharge tube 242 and the water extraction unit 212 is formed too close, the scale (S) exiting the discharge tube 242 can be introduced into the water extraction unit 212 as it is without time margin to reduce the speed, the It is preferable that the separation distance D between the discharge tube 242 and the water outlet 212 is at least 5 mm.

In addition, the scale S mounted on the upper surface of the support plate 241 can move a certain distance due to the vortex of water, but when the operation is stopped because the upper end of the discharge tube 242 is higher than the support plate 241, that is, the discharge tube Even if there is no flow rate passing through 242, the scale S does not flow into the discharge pipe 242. At this time, if the height H of the discharge tube 242 is too low, the scale S may reflow into the discharge tube 242 when a variable such as inclination of the water treatment apparatus occurs. The height H of the 242 is preferably formed to be 5 mm or more.

In addition, the filtering means 240 applied to the present invention, when there is no fear that the scale (S) loaded on the upper surface of the support plate 241 is re-introduced into the electrolytic sterilization means 220, the support plate 241 without the discharge tube 242. It may consist of only.

7 is a cross-sectional view of an embodiment in which the cleaning nozzle and sterilization nozzle included in the bidet according to the present invention are integrally formed.

The cleaning nozzle 510 and the sterilization nozzle 520 applied to the present invention may be manufactured separately as shown in FIG. 3, or may be manufactured integrally as shown in FIG. 7. That is, the washing water passage 550 and the sterilizing water passage 560 are respectively formed in one nozzle housing 500, and a portion in which the washing water passage 550 is formed serves as the washing nozzle 510 and the sterilizing water. The part where the furnace 560 is formed is configured to serve as the sterilization nozzle 520.

On one side of the nozzle housing 500, the cleaning water supply pipe 552 and the water in the sterilization water tank 320 to transfer the water in the cleaning water tank 310 to the cleaning water passage 550 to the sterilization water passage 560. A sterile water supply pipe 562 is provided (see FIG. 3). Therefore, the water filtered by the filter 100 is supplied to the washing water passage 550 of the washing nozzle 510 for washing the anus and the vagina of the user, sprayed through the washing nozzle 512, and the washing nozzle 510. Water sterilized by the sterilizing device 200 is supplied to the sterilizing water passage 560 inside the sterilizing nozzle 520 for sterilizing (particularly around the washing water spraying port 512 into which the washing water is injected). Sprayed through).

The cleaning nozzle 510 includes a fixing part 530 integrally formed in the nozzle housing 500, and a slide part 540 coupled to the fixing part 530 in a drawable and extractable structure. Therefore, even if the sterilization water injection port 522 is fixed, the washing water injection port 512 and its surroundings may be sterilized by the sterilization water through the operation of the slide unit 540.

As described above, the slide unit 540 is drawn in and drawn out to adjust the washing water spraying position according to the characteristics of the user, and thus a detailed description thereof will be omitted since it is a technique applied to the washing nozzle in the conventional bidet.

8 is a block diagram of a bidet second embodiment according to the present invention.

In the bidet according to the present invention, as shown in FIG. 8, both the cleaning nozzle 510 and the sterilizing nozzle 520 are connected to the sterilizing apparatus 300, and the user's anal with sterilizing water sterilized by the sterilizing apparatus 300. But it can be configured to clean the vagina.

In general, the process of preparing the sterilizing water using electrolysis is slower and costs more than the process of preparing the washing water using the filter 100. Thus, as shown in FIG. It is more economical to use only to sterilize 510. However, when cleaning the anus and vagina of the user using sterilized water, as shown in Figure 8, the operating cost is slightly increased, but the effect of cleaning the anus and vagina of the user is significantly improved.

In addition, in order to supply the washing water and the sterilizing water to the washing nozzle 510 and the sterilizing nozzle 520 as shown in FIG. 3, the washing water pump 410 and the sterilizing water pump 420 are separately separated. Although it should be prepared, when the cleaning nozzle 510 and the sterilization nozzle 520 is configured to supply sterilization water as shown in FIG. 8, the cleaning nozzle 510 or the sterilization nozzle 520 with one pump 400. ) Can be selectively supplied to sterilization water.

As mentioned above, although this invention was demonstrated in detail using the preferable embodiment, the scope of the present invention is not limited to a specific embodiment, Comprising: It should be interpreted by the attached Claim. In addition, those skilled in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.

Bidet according to the present invention can be used to clean and sterilize the cleaning nozzle, so that the cleaning nozzle can be used without worrying about the contamination of the cleaning nozzle. In addition, since a separate filter for filtering the scale is not used, manufacturing cost can be reduced and maintenance can be easily performed.
