Abstract

The present invention relates to a valve for controlling the flow rate of the washing water supplied to the bidet. In general, for an electronically operated bidet, the optimal flow rate of the washing water, the pressure of the washing water, and the temperature of the washing water should be appropriate.

Therefore, when the raw water enters the side of the bidet's washing water inlet, the temperature of the raw water and the water pressure of the raw water are not constant, so the water pressure is constant through a separate regulating valve and the water pressure or flow rate of the washing water is adjusted to the level desired by the user. A flow control valve is required for this purpose, and a separate flow meter is provided to maintain proper flow rate and a separate shutoff valve for complete closing or opening of the rinsing water passage. ) Is required.

The washing water provided on the flow path of the washing water passes through the washing water heating heater in order to adjust the temperature of the washing water, and the washing water passing through the heater passes through the washing nozzle or the 2-way valve. The washing water is selectively supplied to the washing nozzle. As described above, controlling the flow rate or water pressure of the washing water and controlling the water temperature in the process of supplying the optimum washing water to the washing nozzle or the washing nozzle may be referred to as the life of the electronic bidet. However, since various types of control valves and controls are connected on the washing water flow path, the installation space inside the bidet increases, so the size of the bidet is large and the flow paths must be formed by connecting a plurality of parts. The probability is increased. In addition, as described above, since a plurality of cleaning water control-related components are required, manufacturing costs are increased, and considerable power is consumed to separately control the components.

The present invention can integrate the above-mentioned cleaning water control components into one component while minimizing the control power, minimizing the installation space, and significantly reducing the manufacturing cost.

The present invention is to control the flow rate and the water temperature of the washing water controlled by the microcomputer program as a component related to the flow control of the electronic bidet to make the user feel refreshed.

In general, in the case of the electronic bidet, the temperature of the washing water is controlled by a predetermined program by detecting a resistance change according to the temperature of the thermistor element so as to maintain the temperature of the washing water by maintaining a heating heater on the flow path of the washing water. The heater is being controlled. However, the flow rate of the washing water should be controlled by continuously measuring the passage cross section of the flow path by measuring the flow rate using a flow meter, which is a separate measuring means. Since the flow rate is proportional to the flow rate, an impeller is installed on a circular curved flow path, and a means of detecting a change of magnetic flux in a photo interrupt or a rotating magnet by a hall element is used. In the case of the electronic bidet currently on the market, the washing water drawn into the bidet is primarily made of a constant pressure valve so that the secondary pressure is constant. Therefore, the flow rate of the washing water is the rotation angle of the control plate that is rotationally controlled by the stepping motor. Is being controlled. Therefore, if the characteristics of the pressure holding spring or the diaphragm of the positive pressure valve are changed by the water temperature or the water pressure, the secondary water pressure of the positive pressure valve may be changed, and thus the washing water injection force in the cleaning nozzle may change.

Therefore, the flow rate of the washing water should be accurately measured by a separate flow measuring means, and compared with the measured value and the value set in the program of the microcomputer, and the feed back of the error amount must be fed back to operate the flow adjusting means. It will be necessary to maintain a constant flow rate.

1, 2, 3 and 4 is a view showing the flow rate control means that is applied to a common electronic bidet, Figure 1 is a cross-sectional view of the constant pressure valve of the flow control related components of the bidet according to the prior art. . Hereinafter, the configuration and operation of FIG. 1 will be described in detail.

The washing water introduced into the washing water inlet 20a passes through the orifice 21a and is discharged to the washing water outlet 20b to adjust the passage passage cross section of the orifice 21a with the adjusting body 21. The diaphragm 28 is installed on the upper part of the orifice and is deformed by being pressed upward by the pressure of the washing water flowing out to the outlet side, and the pressure adjusting springs 30 and 31 are installed on the diaphragm 28. Pressurize the fram. In addition, since the adjusting body 23 is fixed to the adjusting shaft 22 and connected to the diaphragm center, the adjusting body 23 also operates in the same displacement according to the vertical movement of the diaphragm.

Therefore, since the adjuster 23 is operated so that the pressure of the washing water acting on the lower portion of the diaphragm and the holding force of the pressure regulating springs 30 and 31 are the same, The washing water may flow out to the outlet 20b side.

As described above, in the conventional bidet, in the case of the positive pressure valve, the diaphragm 28 in which hydraulic pressure acts and the pressure regulating springs 30 and 31 for applying the corresponding pressure to the diaphragm are applied to the mutual pressure action. The secondary pressure of the washing water flowing out is adjusted to be constant. Therefore, when the pressure characteristics of the diaphragm and the pressure regulating spring change, the secondary pressure also changes. That is, due to the change in the hardness of the diaphragm according to the water temperature of the washing water, or the pressure of the washing water outflow due to the change in the pressure characteristics of the spring has a disadvantage.

Figure 2 shows a cross-sectional view of the flow control valve of the flow control related parts of the bidet according to the prior art. Hereinafter, the configuration and operation of FIG. 2 will be described in detail.

A valve chamber 133 having a washing water inlet 132, an adjusting body 140 installed inside the valve chamber 133 and rotating at a constant speed by the stepping motor 110, and the adjusting body ( It is characterized by consisting of a valve base 130 for guiding the flow rate adjusted through the adjusting through-hole 143 formed in the 140 toward the washing water outlet (not shown), the drive shaft 141 is installed.

As described above, in the conventional flow rate adjusting means, the flow rate is controlled only by the relative rotational displacement of the valve base 130 and the adjuster 140 rotating by a predetermined angle with respect to the valve base 130. Therefore, there is a disadvantage that the flow rate of the washing water discharged to the outlet side is changed according to the water pressure of the washing water introduced into the washing water inlet 132.

Figure 3 shows a cross-sectional view of the solenoid valve among the components related to the flow control of the bidet according to the prior art. Hereinafter, the configuration and operation of FIG. 3 will be described in detail.

The washing water inlet 80 and the washing water outlet 100 are formed, and a valve body 60 having a cylindrical flow path blocking portion 85 formed at the center thereof, and installed above the valve body 60 and operated vertically. A valve housing 40 accommodating the plunger 120, a solenoid 1 installed outside the valve housing 40 to apply magnetic force to the plunger 120, and the valve housing 40 and the valve. The diaphragm 70 is installed between the body 60 and selectively opens and closes the flow path blocking portion 85, and the pilot flow path 90 is formed so that the diaphragm is operated up and down by generating a differential pressure in the upper and lower diaphragms. And an auxiliary blocking member 110 that selectively opens and closes the pilot flow path 90 and interlocks with the plunger 120.

As described above, the solenoid valve for controlling the blocking and opening of the flow path can be applied to domestic water pressure (up to about 7Kg / cm ² ), so that the opening and closing of the flow path is impossible when the plunger 120 is not operated, In addition, since the flow path is opened and closed due to the difference in the hydraulic pressure acting on the upper and lower parts of the diaphragm 70, when the differential pressure is weak, the pressure that the diaphragm presses the flow path blocking portion 85 is low, and there is a high risk of leakage. In addition, the differential pressure is the pressure difference between the inflow and outflow, so when the pressure of the inflow or outflow changes sharply, the diaphragm operating in accordance with the differential pressure vibrates violently, causing noise.

In addition, since the power consumed by the solenoid portion 1 (about 6 W) is quite large, the size of the power supply will be increased.

Figure 4 is an exploded perspective view of the flow rate detection unit among the components related to the flow control of the bidet according to the prior art. Hereinafter, the configuration and operation of FIG. 4 will be described in detail.

A cover 18 having a washing water inlet 16, a body 10 coupled to the cover to form a circular flow path, and a circular flow path installed between the cover 18 and the body 10. An impeller 22 which rotates in proportion to the flow rate of the washing water flowing therein, a plurality of magnets 32 fixed to the impeller 22 to generate magnetic flux while rotating at a constant speed, and installed outside the upper end of the body 10. It is characterized in that it consists of a Hall sensor 12 for detecting the rotational speed of the impeller 22 by detecting a change in the magnetic flux generated by the magnet (32). As described above, the flow rate sensing unit according to the prior art requires a plurality of magnets, and the impeller shape in which the magnets are fixed is obstructed to smoothly move the flow path, so that the impeller 22 does not rotate when the flow rate is small. There was this.

5 is a flow path connection diagram for the components related to the flow control of the bidet according to the prior art. That is, when the washing water flows into the washing water inlet of the electronic bidet connected to the tap water, the pressure reducing valve 1 lowers and maintains the water pressure to a constant pressure, the solenoid valve 2 opening or closing the washing water flow path, and the flow rate. A flow control valve (3) to adjust appropriately, a flow rate sensing unit (4) for measuring the flow rate, a thermistor (5) for sensing the temperature of the fluid, a heater (6) for heating the washing water to an appropriate temperature, It is characterized in that the branch valve 7 is connected in order to selectively supply the washing water to the first spray nozzle or the second spray nozzle 8.

As described above, the components related to the flow control of the washing water flow of the electronic bidet according to the related art are independently applied to each function of the components, and thus, a tube is required to connect the flow paths between the components, and elasticity is necessary to prevent leakage of the connection portion. A band is a must. In addition, since a large amount of space is required to arrange a plurality of flow control-related components inside the electronic bidet, the appearance of the bidet increases. Therefore, the cost of a plurality of independent flow path-related parts, the cost of the flow path connecting parts between the respective parts, and the cost of the exterior parts due to the expansion of the bidet appearance are all increased.

The present invention integrates the components related to the flow path applied to the conventional electronic bidet to significantly reduce the cost, while eliminating the cause of the leakage of the flow path connecting portion, and also makes a significant reduction in the arrangement space of the parts, It is aimed to accurately measure the flow rate so that the optimal flow rate is set to the final injection nozzle and significantly reduce the power consumption consumed in the flow control.

The present invention has been made to solve the above problems, it is applied to the electronic bidet as one component to measure the flow rate of the washing water, and accordingly to adjust the flow rate, opening and closing of the flow path, the incoming washing water It is to provide a flow control valve applied to an electronic bidet that measures the temperature of and outputs a temperature signal for controlling the temperature of the washing water.

That is to achieve the above object by integrating the five independent parts shown in Figure 5 into one in the form of one flow control valve (10).

It will be described with reference to the drawings presented below.

In addition, as shown in Figure 6 shows the appearance of the flow control valve of the bidet according to the present invention. That is, the stepping motor 10 of the rotation driving force providing means is installed in the valve housing 20 in the upper part, and the washing water inlet 30 is formed in the lower part, and the hall element 40 in which the signal of the flow rate is output in the center of the lower part is installed. On one side of the valve housing 20, a channel opening means 40 consisting of a washing water outlet 21 and a solenoid is provided.

On the other hand, the inside of the lower end of the valve housing flow path blocking means (H) consisting of a magnetic material absorbing plate 70, a rubber blocking plate 75, and the second spring (80); A support plate (81) installed at a lower portion of the flow path blocking means (H) to support the second spring (80); A flow rate sensing means (B) installed at the lower portion of the support plate (81) and configured to rotate in proportion to the flow rate, the impeller housing (100), and the hall element (104); A temperature sensing means (A) which penetrates one side of the impeller housing (100) and measures the temperature of the washing water introduced into the impeller housing (100); The channel opening means G is installed on the other side of the Ippeller housing 100 to maintain the adsorption state by the magnetic force of the adsorption plate 70 to maintain the open state of the flow path.

8 and 9 are cross-sectional views showing an exploded perspective view of the flow control valve of the bidet according to the present invention, and constitutes a rotational driving force providing means (C) consisting of a stepping motor 10 and a drive shaft 30 from the top The drive shaft 30 has a motor shaft insertion hole 33 formed at an upper center thereof so as to be rotated at constant speed with the motor shaft 11 provided at the bottom of the stepping motor 10, and a rotation stopper formed at one side of the upper end thereof. 31 comes into contact with the fixed stoppers 41a and 41b formed on the valve base 40, and the rotation is restrained to stop.

The drive shaft 30 is inserted into the valve base 40 to provide rotational force to the control plate 50. In addition, the valve base 40 is inserted into the upper end of the valve housing 20, the flow rate is adjusted according to the relative rotation angle of the control plate 50, the first sealing between the drive shaft 30 and the valve base 40 32 is installed to transmit the driving force to the control plate 50 without leaking the cleaning water inside the valve housing. On the lower portion of the drive shaft 30, a cross-shaped slide groove 34 having a cross section and a cross-shaped slide rib 51 formed on the top of the control plate 50 slide together to rotate the rotational force. The control plate 50 is in close contact with the first sealing surface 47 at the bottom of the valve base 40 while being transferred to the control plate 50.

On the other hand, the rotating through hole 53 formed in the control plate 50 is in close contact with the first sealing surface 47 of the lower end of the valve base 40 to adjust the flow rate. As shown in FIG. 16, the first sealing surface 47 has a first control through hole 45a, a second control through hole 45b, and a third control through hole 45c formed on the same circumference, so as to rotate the through hole. The flow rate is determined in accordance with the passage cross section of the control through-hole 45, which 53 is in close contact and rotates.

On the other hand, the rotating spiral surface 55 formed at the lower end of the adjusting plate 50 is always in close contact with the fixed spiral surface 62 of the lifter 60 installed on the lower portion of the adjusting plate 50 so that the rotating spiral according to the rotation angle The surface 55 pushes up the fixed spiral surface 62 formed on the lifter 60. The lifter 60 has a cross-shaped slide protrusion 63 formed therein, and the slide protrusion 63 is inserted to slide in the first slide groove 25 formed in the valve housing 20. The lifter 60 slides up and down to prevent rotation.

The first spring 60a is installed at the lower end of the first spring support part 27 and the lifter 60 formed in the valve housing 20, so that the lifter 60 is always supported in the upward direction so that the fixed spiral surface 62 ) And the rotating spiral surface 55 are always in close contact with each other, and also the second sealing surface 52 of the control plate 50 is in close contact with the first sealing surface 47 of the valve base 40.

A lifter shaft 64 and a second protrusion 65 are formed at the center of the lower end of the lifter 60, and a suction plate 70 having a magnetic absorbing plate 70 formed on the blocking plate 77 is provided at the lower portion of the lifter shaft 64. It is inserted into the groove 77 and installed. When the stepping motor 10 rotates in the clockwise direction, the lifter 60 slides downward and the lifter shaft 64 at the bottom of the lifter pushes down the blocking surface 78 of the blocking plate 75, thereby preventing the blocking surface ( 78 is spaced apart from the orifice 24 formed in the valve housing to open the flow path. As described above, the operation of the lifter 60 causes the blocking plate 75 and the suction plate 70 to descend downward, so that the suction surface 72 of the suction plate 70 has the first magnetic pole of the flow path opening means G. The first magnetic pole 111a and the second magnetic pole 111b are magnetized by contacting the second magnetic pole 111b and the current flowing through the coil of the flow path opening means G, thereby adsorbing the suction plate 70. ) Is held in a state of being adsorbed by magnetic force. At this time, even if the rotation direction of the stepping motor 10 rotates counterclockwise and the lifter 60 returns to the upper side, the suction plate 70 is absorbed by the magnetic force of the first and second magnetic poles 111a and 111b. The barrier plate 75 fixed to the suction plate 70 is also spaced apart from the orifice 24 to maintain an open state of the flow path.

That is, as illustrated in FIG. 16, the flow rate Q for each rotation angle according to the clockwise rotation state 150 and the counterclockwise direction 151 of the control plate 50, the movement height H of the lifter 60, and , The holding current I flowing in the flow path opening means G is shown graphically. That is, when the control plate 50 starts to rotate in the clockwise direction 150, the flow path is opened by the lift 60, but the position of the rotation hole 53 of the control plate is the third control hole 45c of the valve base 40. Since a small flow rate flows out, and the control plate 50 is rotated further clockwise to come to the position of B, the lift movement is maximized, as described above, the adsorption surface 72 of the adsorption plate 70 ) Is in contact with the first magnetic pole 111a and the second magnetic pole 111b of the flow path opening means G, and the coil of the flow path opening means G is energized, so that the first magnetic pole 111a and the first The two magnetic poles 111b are magnetized to maintain the adsorption plate 70 in a state of being adsorbed by magnetic force.

When the control plate rotates in the counterclockwise direction 151 to be in the B position, the adsorption plate 70 maintains the adsorption state by the magnetic force of the first and second magnetic poles 111a and 111b and the adsorption plate 70. Block plate 75 is also fixed to the orifice 24 to maintain the open state of the flow path, the control plate is rotated further counterclockwise to the C position lifter 60 is the blocking plate 75 Spaced apart from the blocking surface 78 of the descending along the oblique surface. Therefore, the movement path of the lifter 60 rises in the form of the graph 161a, but the adsorption plate 70 and the blocking plate 75 stay in the adsorbed position in the form of the graph 161 to maintain the open state. . In the counterclockwise direction 151 further from the C position to the D position, since the position of the rotary through hole 53 of the adjustment plate is located in the second control through hole 45b of the valve base 40, the intermediate flow rate flows out. The adsorption plate 70 maintains the adsorption state by the magnetic force of the first and second magnetic poles 111a and 111b, and the blocking plate 75 fixed to the adsorption plate 70 is also spaced apart from the orifice 24. To keep the flow path open.

Subsequently, when the adjusting plate 50 is further rotated in the counterclockwise direction 151 to the E position, the position of the rotating hole 53 of the adjusting plate is located in the first adjusting hole 45a of the valve base 40. The flow rate flows out, and the adsorption plate 70 maintains the adsorption state by the magnetic force of the first and second magnetic poles 111a and 111b, and the blocking plate 75 fixed to the adsorption plate 70 is also the orifice ( Keep the flow path open in a spaced apart state from 24). When the holding current of the flow path opening means G is blocked in the above state (F position), the first and second magnetic poles 111a and 111b lose their magnetic force and the adsorbed adsorption plate 70 becomes the first and second magnetic poles. It is separated from the (111a, 111b), the blocking surface 78 of the blocking plate 75 by the second spring 80 is in close contact with the orifice 24 surface to close the flow path.

Therefore, the flow control valve of the bidet according to the present invention is a step of opening the flow path (ABC step), adjusting the flow rate at a specified angle (C ~ E), and closing the flow path by blocking the adsorption holding current (F ), Etc., characterized in that the operation of the flow control valve is made in three steps.

In addition, since the adsorption plate 70 is not attracted by the magnetic force of the solenoid as described above, the adsorption plate 70 is adsorbed using the rotational driving force of the stepping motor 10. Therefore, it is not necessary to apply a strong magnetic force to the solenoid. When it is adsorbed to maintain the adsorption state, the adsorption is maintained even with very small magnetic force, so very small power (about 0.5W) is consumed compared to the power consumption (about 6W) of the conventional solenoid valve. The size and cost of the power supply (transformer, rectifier circuit, etc.) for powering the solenoid will also be significantly reduced. In addition, since the lifter 60 moves the blocking plate 75 and the adsorption plate 70 toward the magnetic pole 111 at a substantially slow speed of about 1 mm / sec., The impact noise due to mutual contact during lift is hardly generated. When the flow path is blocked by blocking the holding current of the solenoid, only the low noise noise generated when the rubber blocking plate 75 strikes the orifice 24 is generated.

9, the support plate 81 is installed between the flow path blocking means (H) and the flow rate sensing means (B) to close the upper part of the impeller chamber to form a rotating flow path so that the impeller rotates smoothly. The second slide protrusion 84 formed to protrude upward from the center of the 81 is inserted into the second slide hole 79a formed under the blocking plate 75 so as to slide, and the first support hole 86 formed at the lower portion thereof. The second impeller shaft (92b) is inserted into a role to support the rotation. In addition, the support plate 81 is formed with a third through-hole 88 at a predetermined distance from the center, so that the washing water is moved from the impeller chamber 107 to the valve housing 20 side. In addition, the support plate 81 has a first stimulation fixing projection 82a and a second stimulation fixing projection 82b are formed at a position spaced from the center by a predetermined distance to serve to compress and fix the magnetic pole of the flow path opening means (G). Do it.

Referring to FIGS. 8 and 9, the flow path of the washing water may include a third inlet 101, an injection hole 102, an impeller chamber 107, and a support plate 81 formed on one side of the impeller housing 100. The through-hole 88, the orifice 24 of the valve housing 20, the rotary through-hole 53 of the adjustment plate 50, the first control through hole 45a or the second control through hole 45b of the valve base 40 or the first The washing water is passed in the order of the three adjustment through holes (45c), the first through holes (43), the outlet 21 of the valve housing (20).

It shows the state which cuts off (24).

12 is a cross-sectional view of the temperature sensing means (A) and the flow rate sensing means (B) of the flow control valve of the bidet according to the present invention the washing water introduced through the washing water inlet 101 is inside the impeller chamber 107 It flows into the circular flow path 122 of the impeller 90 is installed to rotate in the impeller chamber 107 is rotated in proportion to the speed of the fluid. Accordingly, the cylindrical shape inserted into the lower portion of the impeller 90 rotates the magnet 95 and detects a change in the magnetic flux generated by the rotating magnet with the Hall element 104 to detect the flow rate. The washing water inlet flow passage 122 forms a venturi 102 having a smaller passage cross section at the point where it intersects with the impeller chamber, so that the washing water is quickly drawn into the impeller chamber, so that the impeller 90 rotates smoothly even at a low flow rate. It is a feature of the present invention.

In addition, a thermistor 120 for sensing the temperature of the washing water is installed at one side of the impeller chamber 107 to constitute a temperature sensing means (A), and the thermistor 120 at the impeller chamber 107 at the central portion thereof. The fourth sealing 121 is inserted to prevent leakage to the installation portion.

Therefore, the magnetic flux generated in the coil 115 constitutes a magnetic circuit composed of the core 116, the first magnetic pole 111a, the second magnetic pole 111b, and the adsorption plate 80, and constitutes the core (( 116, the first magnetic pole 111a and the second magnetic pole 111b, the adsorption plate 80 is characterized in that the magnetic material is a small residual magnetic.

14 is a cross-sectional view of the lift means (F), the flow path opening means (G) and the flow path blocking means (H) of the flow control valve of the bidet according to the present invention. In the sectional view G-G, the adjusting plate 60 is rotated counterclockwise so that the rotation stopper 31 of the drive shaft 30 is restrained and stopped by the fixed stopper 41b of the valve base 40. In this state, the rotating spiral surface 55 formed below the adjusting plate 50 pushes down the fixed spiral surface 62 of the upper part of the lifter 60 by the height H, and the lifter formed on the lifter 60.

The flow rate control valve of the bidet according to the present invention relates to a valve for controlling the flow rate of the washing water supplied to the bidet, by controlling the flow rate of the washing water that is most suitable for washing and by measuring the temperature of the washing water, The main serves to provide the temperature information of the incoming water to be applied to the heater. In addition, since it consists of one valve driven by one stepping motor by integrating a plurality of components related to flow control applied to a conventional electronic bidet, the components related to the flow control (static pressure valve, flow control valve, shutoff valve, flow measurement) Device, temperature measuring device, etc.) can be significantly reduced, eliminating the fear of leakage of the cleaning water at the flow path connection between the flow control related components, while reducing the raw water of the entire components related to the flow control The company will be able to significantly reduce costs. In addition, as described above, since the flow path connecting member between the components is not required in the related art, the connection member cost and the connection work cost may also be drastically reduced.

Moreover, in the related art, a separate stepping motor is applied to the flow regulating valve and a separate solenoid valve is applied to the shutoff valve, which consumes about 7 W of driving power. However, about 1.5 W of the bidet flow regulating valve according to the present invention. Since only heat is consumed, the heat generated in the driving parts (stepping motor, solenoid) is extremely low, and the size and cost of the power supply unit (transformer, rectifier circuit, etc.) for providing the driving current to the parts will be drastically reduced. In the prior art, when the opening and closing of the washing water using the solenoid valve, accompanied by the noise noise between the plunger and the core of the solenoid, and the abnormal vibration noise of the diaphragm, in the case of the bidet flow control valve according to the present invention, The drive noise of the extremely low stepping motor and the extremely low impact sound produced by the blocking plate (rubber material) hit the orifice, making it almost silent for consumers.
