It is related with the equipped bidet.

The bidet is a device for automatically cleaning the anus or local area after the toilet, and instead of using a tissue or the like, the bidet gently cleans using the washing water of a suitable temperature emitted from the center of the device.

Although such a bidet was originally developed as a women's local scrubber, it has been widely used by men and women of all ages recently as the perception that it is much cleaner for hygiene to clean the anus after toileting with toilet paper, etc. By washing with water, it is possible to prevent bacterial infections, thereby preventing the development of anal diseases including hemorrhoids, and it is effective in obstetrics and gynecological diseases such as cold chills, and improves the convenience of toileting of the elderly and obese. Has a wide variety of functions.

Such a bidet is usually mounted on the top of the toilet body, the bidet main body (1) is provided with a bucket for filtering and storing the washing water supplied from the water pipe, the sprayed stored water to the local or anal area respectively by the user's choice Bidet cleaning nozzle (or anal cleaning nozzle) (2), seating (3) for the user seated to view the toilet, and control unit (4) for the user to adjust the function of the bidet according to the situation as an essential component It is configured to include.

It can be used to perform local / anal cleaning.

Recently, a lot of functional bidets have been developed that give additional functions such as massage functions, steam bath functions, and moxibustion functions to the general functions of the bidet, thereby playing a role of widening the application area of the bidet.

As such, a water tank for temporarily storing the washing water introduced into the bidet is provided. Furthermore, the water tank not only stores the washing water but also simultaneously performs a function of warming the washing water to an appropriate temperature at which the user does not feel uncomfortable when the washing water touches the human body.

To heat the water, a heater installed inside the water tank is activated to heat the water to the proper temperature. In the process, if the water supplied to the bidet from the outside is not water supplied to the inside of the water tank, but if the heater is heated there is a problem that may cause serious damage to the bidet as well as a safety accident such as a fire.

In addition, the washing water flowing in the bidet may be supplied with air bubbles included, there is a problem that it is impossible to accurately measure the flow rate of the washing water because the flow rate is measured while including the air bubbles while measuring the flow rate of the washing water.

Accordingly, the present invention has been made in view of the above-mentioned conventional defects, and it is possible to accurately measure the amount of washing water flowing in the bidet, and to measure whether the washing water is properly supplied from the outside.

The overall structure of the bidet according to the present invention basically includes all of the structures of FIG. 1 with respect to a general bidet. Accordingly, the bidet according to the present invention has a bidet body (1) is provided on the top of the toilet body is provided with a bucket for filtering and storing the washing water supplied from the water pipe, the local or anal area respectively by the user's choice Bidet cleaning nozzle (or anal cleaning nozzle) (2) to spray on, the seat (3) for the user to sit on the toilet to see the toilet, and the control unit (4) for the user to adjust the function of the bidet according to the situation It is configured to include as an element.

Here, since the structures of the bidet cleaning nozzle 2, the seat 3, and the control unit 4 are known in the art, a detailed description thereof will be omitted. However, the overall operating state is described below.

In the bidet according to the present invention, when the user selects and presses the anal cleaning button or the bidet cleaning button of the control unit 4 after the toilet sitting on the seat 3, the bidet cleaning nozzle (or anal cleaning nozzle) corresponding to the selected function. (2) A method in which the washing water heated to an appropriate temperature in the water tank mounted on the main body 1 is protruded a certain distance, and then sprayed at a hydraulic pressure suitable for a selected function to clean the local or anus and finally dry it by heating. It can be used to perform local / anal cleaning.

In order to maintain the temperature of the washing water properly in this process, the washing water is heated to a controlled temperature in which the user can feel comfortable in the water tank mounted in the main body 1 and then sprayed through the nozzle.

FIG. 2 is a perspective view of an exploded main body 1 'showing the interior of the main body 1 shown in FIG. 3 is a plan view of FIG. 2. Although details and illustrations of components other than those directly related to the features of the present invention are omitted in FIGS. 2 and 3, additional components may be mounted that relate to the operation of the actual bidet.

Inside the case, a pressure reducing valve 50 is mounted in which water supplied from the outside is directly connected and the pressure is reduced to an appropriate pressure in the apparatus in the bidet. For example, a solenoid valve may be used as the pressure reducing valve 50.

The introduced washing water passing through the pressure reducing valve 50 is introduced into the water tank 20 through the connection pipe. A heater assembly is mounted at one side of the water tank 20, and the heater assembly functions to warm water introduced into the water tank 20 to an appropriate temperature.

The washing water heated to the appropriate temperature controlled in the water tank 20 flows into the pressure control valve 30 disposed above the water tank 20. The pressure control valve 30 mixes the warmed washing water with the outside air, prevents excessive pressure rise inside the water tank 20, and mixes the washing water with the air to discharge the gas in a state matched to the pump exposure. do.

The washing water passing through the pressure control valve 30 flows into the flow rate measuring valve 40, and after the flow rate of the washing water is checked, it is discharged through the nozzle 2. A circuit board (not shown) that controls the operation of the components during this process is disposed on the circuit board support 60.

4 is an exploded perspective view of a disassembled flow measurement valve according to an embodiment of the present invention.

Referring to FIG. 4, the flow rate measuring valve for a bidet according to the present invention includes a rotor 80 rotating about a pin 49 between a base 81 and a cover assembly. Here, the cover assembly includes an inlet 41 through which the washing water is introduced and an outlet 46 through which the washing water is discharged, and has an inner shape corresponding to the rotor 80 to accommodate the rotor 80 separately. do. In addition, the cover assembly is provided with a receiving opening 45 (FIG. 6) into which the temperature sensor 47 is inserted.

A fastening part 91, into which a rotation sensor 93 (FIG. 7) for detecting the rotational speed of the rotor 80 is inserted and mounted, is disposed on the cover assembly of the flow measuring valve, and the flow measuring valve is connected to the water tank 20. Fixing ring 92 into which the fastening member is inserted may be disposed on both sides of the cover assembly to fix the upper surface of the cover assembly.

Meanwhile, FIG. 5 is a perspective view of the rotor 80 accommodated in the cover assembly. The rotor 80 includes a ring-shaped inclined surface 82, a core portion 86 disposed at the center of the inclined surface, and at least one impeller 84 extending radially from the core portion to the inclined surface. .

The magnet part 88 is disposed above the core part so that the rotation of the magnet part is measured by the rotation sensor 93, and thus the rotation speed per unit time of the rotor is measured. In the center of the core portion 86 and the magnet portion 88 is formed a center groove 89 into which a pin 49, which is a central axis of rotation of the rotor, is inserted, and the pin 49 is the center groove. Penetrates (89).

On the other hand, as shown in Figure 5, the impeller 84 is further protruded by the height (h) below the lower end of the inclined surface (82).

FIG. 6 is a cross-sectional view taken along the line VI-VI of FIG. 4.

4 and 6, the inlet 41 is not aligned with the center groove 89 or the entire rotor of the rotor 80, but has a half portion of the rotor 80. It is arranged in a biased manner. In other words, the inlet 41 is oriented deviated from the center groove 89 of the rotor. More specifically, the inlet 41 is aligned with the inclined surface 82 and the impeller 84 in diameter and height.

Due to the arrangement of the inlet as described above, the fluid flowing through the inlet contacts the inclined surface 82 and the impeller 84. However, the fluid flowing into the flow rate measuring valve is not a washing water consisting of pure water but a fluid in which air bubbles are mixed with the washing water. Therefore, when the flow rate is measured for the fluid mixed with air bubbles in the washing water, the fluid flow measurement value more than the correct flow rate of the washing water is detected.

In order to solve this problem, it is necessary to separate the air mixed in the washing water with the washing water before measuring the fluid flow rate. As a structure for achieving this purpose, the inlet 41 is aligned with the inclined surface 82 and the protruding impeller 84 of the rotor 80.

Therefore, the air mixed with the washing water flowing into the inlet 41 reaches the rotor at the same time, but the air flows by bypassing the upper side of the rotor 80 on the inclined surface of the rotor 80. This is because air is floated upward because the density is lower than that of the washing water. In consideration of this point, the inclined surface 92 is inclined upward.

In FIG. 6 the flow path of air is shown by arrow A. FIG. Therefore, the air flows along the inclined surface 92 of the rotor 80 to the upper side of the rotor 80 to pass through the air flow path 43 for guiding the air.

Meanwhile, the air flowing into the inlet 41 and the washing water flow upward along the inclined surface 82, whereas the washing water is less dense than the air, so that the washing water flows horizontally as it is, and protrudes below the inclined surface 82. The impeller 84 is shocked to rotate the rotor 80 in the same principle as the watermill.

In this process, the rotation speed of the rotor 80 is detected by the rotation sensor 93 which is a hall sensor, and the flow amount of only the washing water is measured. Since it is well known to measure the fluid flow rate by measuring the rotation speed per unit time by the sensor, a detailed description thereof will be omitted herein.

The flow path through which the washing water passes is indicated by an arrow in FIG. 6. As shown in FIG. 6, the washing water impacts the impeller 84 to rotate the rotor 80 and then flows into the washing water flow path 44 disposed completely past the rotor.

The air flow path 43 through which the air is separated and flows, and the washing water flow path 44 through which the washing water flows after rotating the rotor are joined again. That is, in order to measure the flow rate, the washing water and the air are temporarily separated, and after the flow rate of the washing water is measured, the washing water is mixed again and the soft washing water is restored.

Thus, the washing water flow passage 44 and the air flow passage 44 are joined to the outlet 46 after joining.

7 is a perspective view taken along the line VII-VII of FIG. 4.

As shown in FIG. 7 and as described above, the rotor 80 has a ring-shaped inclined portion 82 which is connected to an impeller 84 extending radially from the core portion 86. It is supported. The impeller 84 protrudes below the lower end of the inclined surface 82 by a height, so that the washing water impacts the protruding impeller so that the rotor 80 rotates about the pin 49.

According to the flow rate valve for bidet according to the present invention,

First, it is possible to measure the precise flow rate of purely pure water only by separating the pure water and air from the fluid mixed with the pure water.

Second, when the feed water supplied to the bidet is cut off, it is possible to detect that there is no flow by the washing water, thereby preventing the bidet from operating in the singular state.

Third, after separating the washing water and the air to measure the flow rate of the washing water, the fluid can be reduced again in a state in which the washing water and the air are mixed, so that the user can use the washing water having a soft feeling including air bubbles.

Although the present invention has been described with reference to the embodiments shown in the drawings, these are merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
