Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 and 5, the bidet apparatus 100 according to the present invention includes a washing water spray nozzle unit 130 and a washing water spray nozzle unit provided in the bidet main body 120 provided in the toilet seat 110. 130 is provided in the nozzle displacement drive unit 140 and the toilet seat 110 to drive the washing water injection nozzle unit 130 so that the injection position of the washing water injection nozzle unit 130 is changed according to the user's seating position. Seating detection unit 150 is provided on the left and right sides of the toilet seat 111 to detect the user's seating pressure, and based on the results detected by the seating detection unit 150 to determine the user's seating position and determined It includes a control unit 160 for controlling the nozzle displacement drive unit 140 so that the injection position of the washing water injection nozzle unit 130 is variable according to the seating position.

Accordingly, the washing water may be sprayed at the correct position by aiming the local part of the user according to the seating position of the user.

As shown in FIG. 2 or FIG. 4, the washing water spray nozzle unit 130 performs at least one of cleaning and bidet, and the standby position accommodated in the bidet main body 120 and the outside of the bidet main body 120. The nozzles 131 and 133 provided to be movable between the spraying positions for spraying the washing water, the nozzle cases 135 to which the nozzles 131 and 133 are movable, and the nozzle cases 135 to the nozzle cases 131 and 133. ) Includes a nozzle driver 137 driving the nozzles 131 and 133 by a control command of the controller 160 to move between the standby position and the injection position.

In one embodiment of the present invention, the washing water injection nozzle unit 130 is preferably provided with a cleaning nozzle 131 and a bidet nozzle 133 to perform the cleaning and bidet functions in the nozzle case 135, respectively.

The nozzle displacement driving unit 140 is provided with a stepping motor fixed to the bidet body 120, and as shown in FIG. 2 as an embodiment of the present invention, is coupled to the rear of the nozzle case 135. The washing water spray nozzle unit 130 is rotated clockwise or counterclockwise by a predetermined angle by a control command of the controller 160 according to the user's biased seating position.

As an embodiment of the present invention, the nozzle displacement driving unit 140 is described as rotating the washing water injection nozzle unit 130, as another embodiment of the present invention, as shown in Figure 4, the nozzle displacement driving unit ( 140 is a stepping motor coupled with a pinion engaged with a rack formed in the nozzle case 135, and the washing water spray nozzle unit is controlled by a control command of the controller 160 according to the user's biased seating position. The 130 may be horizontally moved by a predetermined distance.

The seat detection unit 150 may be provided as various types of pressure sensing sensors such as strain gauges, load cells, piezoelectric elements, and the like. As an embodiment of the present invention, as shown in FIG. 1, the seat detecting unit 150 is described as one provided at each of the left and right sides of the toilet seat 111, but the control unit 160 has a more accurate seating pressure. Seating detection unit 150 may be provided in plurality on each of the left and right sides of the toilet seat 111 to determine the distribution.

Accordingly, when the user's seating pressure is sensed by the seating detection unit 150, since the measured value of the left and right sensors is changed by the weight difference detected when the seated position of the user is not correct on the toilet seat 111, the controller Since different measurement values are input to the input ports input to the 160, the control unit 160 controls the nozzle displacement driving unit 140 to rotate the washing water spray nozzle unit 130 by a predetermined angle. The injection position may be varied by varying or moving the washing water injection nozzle unit 130 in parallel by a predetermined distance.

For example, as shown in FIG. 3, the controller 160 adjusts the rotation angle X according to the injection target section L when the distance from the user's local to the water outlet of the nozzles 131 and 133 is approximately 10 cm. The trigonometric (arctan) operation yields

L = ± 1 cm: X ≒ ± 5.7 °

L = ± 2 cm: X ≒ ± 11.3 °

L = ± 3 cm: X ≒ ± 16.7 °

L = ± 4 cm: X ≒ ± 21.8 °

L = ± 5 cm: X ≒ ± 26.5 °

Therefore, as an example, when performing the cleaning function, the spraying target section L is set to a range of ± 3 cm so that the nozzle displacement driving unit 140 rotates the washing water spray nozzle unit 130 within approximately ± 16.7 °. Can control the nozzle displacement drive unit 140, and when the bidet function is performed, the spray target section L is set to a range of ± 5 cm so that the nozzle displacement drive unit 140 moves the washing water spray nozzle unit 130 to approximately ± 26.5 °. The controller 160 may control the nozzle displacement driver 140 to rotate inside.

More specifically, since the local position of the user is inclined toward the user's seating pressure, the controller 160 rotates the washing water spray nozzle unit 130 according to the spray target section so that the washing water is sprayed in the corresponding direction. Rotate the angle (X) to adjust the spray angle of the wash water. This injection angle adjustment step is calculated by dividing the maximum value of the measured value deviation of the seating detection unit 150 provided on the left and right sides of the toilet seat 111 by the injection target section. That is, assuming that the seating detection unit 150 deviation value is 100 when all the seating pressure of the user is loaded on the left side of the toilet seat 111 and only the contact is on the right side, the deviation value is 0 to 25 days when the cleaning function is performed. In this case, the washing water spray nozzle unit 130 is controlled to be positioned at an initial position (center point), and when the deviation value is 26 to 50, the washing water spray nozzle unit 130 is controlled to be rotated approximately 5.7 ° from the initial position. 51 to 75, the washing water spraying nozzle unit 130 is controlled to rotate about 11.3 ° from the initial position, and when the deviation value is 76 to 100, the washing water spraying nozzle unit 130 is controlled to rotate about 16.7 ° from the initial position. do.

Accordingly, after the nozzles 131 and 133 are advanced from the standby position to the spray position by the nozzle driver 137, the controller 160 controls the nozzle displacement driver 140 to change the washing water spray angle in a rotational manner. Depending on the seating position, the user's local points can be aimed to ensure that the wash water is sprayed at the correct position.

In the case of controlling the nozzle displacement driving unit 140 according to another embodiment of the present invention, as shown in FIG. 3, when the cleaning function is performed, when the deviation value is 0 to 25, the washing water spray nozzle unit 130 is initially initialized. Control to be positioned at the position (center point), and if the deviation value is 26 to 50, the washing water spray nozzle unit 130 is controlled to move 1 cm from the initial position, and if the deviation value is 51 to 75 washing water spray nozzle unit 130 ) Is controlled to move 2 cm from the initial position, and when the deviation value is 76 to 100, the washing water injection nozzle unit 130 is controlled to move 3 cm from the initial position.

Accordingly, as shown in FIG. 4, the controller 160 controls the nozzle displacement driver 140 to change the washing water spraying position in a horizontally parallel manner to aim the user's local part according to the user's seating position, thereby accurately positioning the user. The washing water can be sprayed on.

Meanwhile, as shown in FIG. 2 or 4, the bidet device 100 further includes a nozzle position detecting unit 170 provided on a variable path of the washing water injection nozzle unit 130, and the controller 160. ) Is the nozzle displacement driving unit 140 so that the position of the washing water spraying nozzle unit 130 is corrected to the initial position when the washing water spraying nozzle unit 130 is not at the center point based on the result detected by the nozzle position detecting unit 170. It is desirable to control.

The nozzle position detecting unit 170 according to the present invention is preferably provided with an optical sensor for detecting the approach of the washing water spray nozzle unit 130. More specifically, protrusions 135a are formed at both sides of the nozzle case 135, and the nozzle position detecting unit 170 has a light emitting unit and a light receiving unit with a groove through which the protrusion 135a of the nozzle case 135 enters. It is preferable that it consists of. In addition, the nozzle position sensing unit 170 may be provided in pairs so as to be disposed at positions corresponding to the maximum displacement limit of the variable path on the variable path of the washing water injection nozzle unit 130, and the washing water injection nozzle unit 130. Only one may be provided at any one point on the variable path of, for example, an initial position (center point).

Accordingly, the controller 160 controls the nozzle displacement driver 140 to allow the washing water spray nozzle unit 130 to approach any one of the pair of nozzle position detecting units 170, thereby pre-determining the washing water spray nozzle unit 130. On the basis of the displacement amount (rotation angle or horizontal movement distance) of any one of the pair of nozzle position detection unit 170 from the initial position (center point) of the) to correct the position of the washing water injection nozzle unit 130 to the initial position Can be. Meanwhile, even when only one nozzle position detecting unit 170 is provided at any one point on the variable path of the washing water spraying nozzle unit 130, the controller 160 may vary the nozzle position detecting unit 170 at a predetermined initial position. The position of the washing water spray nozzle unit 130 may be corrected to the initial position based on the displacement amount up to one point on the path. On the other hand, the initial stage of the washing water spray nozzle unit 130 based on the time or the amount of displacement until the projection 135a of the washing water spray nozzle unit 130 is detected by the nozzle position detecting unit 170. The location can be determined.

The controller 160 receives all the data required by the controller 160 and transmits the received data to the controller 160.

As shown in FIG. 5, the storage unit 190 receives and stores all data required by the controller 160 and stores the data, and stores the data stored in response to a request from the controller 160. Forward to 160.

Accordingly, the bidet efficiency can be further increased by aiming the local part of the user according to the user's seating position so that the washing water is sprayed at the correct position. Control of the injection position can be performed more accurately. In addition, when the spraying positions of the nozzles 131 and 133 are adjusted and the washing water is stopped, for example, even when the power supply is suddenly cut off during the use of the bidet device 100, a means for correcting the center point of the nozzles 131 and 133 is provided. It is possible to more accurately control the washing water injection position of the 131,133.

The process of controlling the washing water spraying position of the bidet device 100 according to the present invention will be described with reference to FIGS. 1 to 6.

After the washing water spraying of the bidet device 100 is finished in the previous use step, the spraying position of the washing water spraying nozzle unit 130 is initialized, that is, is placed at the center point on the variable path of the washing water spraying nozzle unit 130. The control unit 160 determines whether the nozzles 131 and 133 are located at the center point, that is, the initialization state, based on the information performed in the previous use step stored in the storage 190 (S100).

Next, when it is determined in step 100 that the position of the washing water spray nozzle unit 130 is in an initialized state, the user's seating pressure is sensed through the seating detecting unit 150 (S200), and based on the detected seating pressure Determine the seating position of the user. If it is determined in step 100 that the position of the washing water spraying nozzle unit 130 is not in an initialized state, for example, the power supply is suddenly cut off during the use of the bidet device 100 in the previous use step, so that the washing water spraying nozzle unit 130 is removed. If the injection position of the is not returned to the initialization state, the control step jumps to step 600 to initialize the position of the washing water injection nozzle unit 130.

In one embodiment of the present invention, the initializing the position of the washing water spray nozzle unit 130 of the control step 600, the washing water spray nozzle on the variable path of the washing water spray nozzle unit 130 through the nozzle position detection unit 170 The nozzle displacement driving unit 140 is controlled to initialize the position of the washing water spraying nozzle unit 130 according to a result of sensing the approach of the unit 130 and the approach detecting step of the washing water spraying nozzle unit 130 to spray the washing water. It is preferable to include the step of moving the nozzle unit 130 to the center point on the variable path.

More specifically, in the detecting of the approach of the washing water spray nozzle unit 130, the controller 160 moves the nozzle displacement driving unit 140 such that the washing water spray nozzle unit 130 is moved to a maximum displacement limit point in one direction on the variable path. ) By the entrance groove between any one of the light emitting unit and the light receiving unit of the nozzle position detection unit 170 disposed at the maximum displacement limit point on the variable path of the washing water injection nozzle unit 130. It is preferable that the step of detecting that the washing water injection nozzle unit 130 approaches the maximum displacement limit point through the projection (135a) is entered.

On the other hand, if the user inputs whether to perform the cleaning function or bidet function through the input unit 180, the controller 160 determines whether the input through the input unit 180 is to perform the cleaning function (S300).

If it is determined in step 300 that the input through the input unit 180 is to perform the cleaning function, the control unit 160 is within the cleaning injection target section (rotation angle ± 16.7 ° or horizontal distance ± 3 cm relative to the center point of the nozzle) The injection position of the cleaning nozzle 131 is varied according to the seating position of the user determined in step S400, and the controller 160 opens a water supply valve (not shown) connected to the cleaning nozzle 131 to perform the cleaning function. After spraying the washing water (S500), the nozzle displacement driving unit 140 is controlled to initialize the positions of the nozzles 131 and 133 (S600).

If it is determined in step 300 that the input through the input unit 180 is not for performing the cleaning function, the controller 160 determines whether the input through the input unit 180 is for performing the bidet function (S310). .

If it is determined in step 310 that the input through the input unit 180 is to perform the bidet function, the control unit 160 is within the bidet injection target section (rotation angle ± 26.5 ° or horizontal distance ± 5 cm relative to the center point of the nozzle) The injection position of the bidet nozzle 133 is varied according to the seating position of the user determined in step S320, and the control unit 160 opens the water supply valve (not shown) connected to the bidet nozzle 133 to perform the bidet function. After spraying the washing water (S330), the nozzle displacement driving unit 140 is controlled to initialize the positions of the nozzles 131 and 133 (S600).

If it is determined in step 310 that the input through the input unit 180 is not for performing the bidet function, the control step is jumped to the end.
