For the sake of distinction, the structural features of the movable plate 310 are shown in dashed lines and the structural features of the fixed plate 320 are shown in actuality. In this embodiment, the first washing flow path and the second washing flow path may correspond to the hip-washing flow path and the bidet-washing flow path, respectively, so that the dispensing valve may perform hip-washing, bidet-washing, and self-cleaning functions.

Fig. 4(a) shows a state in which the selected angle of the drive motor is 0 °, and this state is the home position of the movable disk 310 of the distribution valve 300. In this state, the through-holes 311 of the movable tray 310 and the through-holes 321 of the stationary tray 320 are communicated with each other, and in this state, the washing water is sprayed from the self-cleaning nozzles 430 of the washing nozzle unit 400, and the hip washing nozzles 410 or the bidet washing nozzles 420 are cleaned.

In the state of fig. 4(a), when the movable board is rotated about 90 ° clockwise about the rotation axis, the state of fig. 4(b) is obtained. In fig. 4(b), the through hole 311 of the movable tray 310 is communicated with the first cleaning hole 323b of the first cleaning flow path 323 of the stationary tray 320, so that the cleaning water is discharged from the hip nozzles 410 of the cleaning nozzle unit 400, and the residual cold water in the pipes of the hip nozzles 410 can be rapidly discharged.

Example two

As shown in fig. 4 to 5, a second embodiment of the present invention provides a sanitary washing apparatus, including: the seat cover 002; a seat ring 003; an operation unit 600 capable of various operations by a user; a washing and rinsing nozzle unit 400 for spraying the supplied washing water to the private parts of the human body; further, as shown in fig. 5, the sanitary washing apparatus further includes a water supply unit 100 which intakes washing water from a water supply source; a heating unit 200 for heating the washing water having passed through the water supply unit 100; a distribution valve 300 for distributing the flow path and adjusting the flow rate of the heated washing water; a washing nozzle unit 400 for spraying washing water passed through the distribution valve to a human body, a control unit 500 for controlling the water supply unit 100, the heating unit 200, the distribution valve 300, and the washing nozzle unit 400, and a manipulation part 600 for sending a user operation command to the control unit 500. The water supply unit 100 is provided with a water inlet solenoid valve having an opening and closing function. The heating unit 200 instantaneously heats the washing water by a heating member such as a ceramic heater. Further, a temperature sensor or the like for detecting the temperature of the washing water is provided downstream of the heating unit.

The control unit is used for controlling the actions of the water supply unit, the heating unit and the nozzle unit and the rotating angle of the movable disc in the distribution valve.

The nozzle unit includes a hip-wash nozzle 410, a bidet nozzle 420, and a self-cleaning nozzle 430. The self-cleaning nozzle 430 is disposed to spray washing water toward the hip-wash nozzle 410 and the bidet nozzle 420. The hip-wash nozzle 410 and the bidet nozzle 420 are extended and retracted by a driving mechanism, not shown, and are stored in the sanitary washing apparatus 001 when not in use, and are extended to a position set by a user when in use, and the washing water is sprayed toward the private parts of the human body at the position.

The working principle and the process of the sanitary cleaning device of the embodiment comprise the following steps:

and S1, after the washing function is started, the water supply unit is opened to supply water to the distribution valve, and the heating unit is started to heat the washing water. Specifically, after sitting, the user presses a hip washing function button, not shown, of the control unit 600, the control unit 500 controls the water supply unit 100 to be turned on, and the heating unit 200 instantly heats the washing water;

and S2, controlling the movable disc of the distribution valve to rotate to the position of the through hole 311 at the cleaning hole at the far end of the cleaning flow path corresponding to the cleaning function, and draining the cleaning flow path for 2-4 seconds.

In this step, the distribution valve 300 selects a washing water flow path for discharging cold water, specifically:

when the driving motor 330 rotates clockwise by 90 degrees, the movable board 310 starts to switch from the origin shown in fig. 4(a) to the state shown in fig. 4(b), and in the state shown in fig. 4(b), the hip cleaning flow path 323 is fully opened, and the residual cleaning water in the hip cleaning flow rate is discharged from the hip cleaning nozzle in the maximum flow rate state.

S3, controlling the movable disc of the distribution valve to rotate until the through hole 311 is located at the position of the self-cleaning flow path, so that the water discharged from the self-cleaning flow path flushes the corresponding nozzle, and meanwhile, the corresponding cleaning flow path discharges residual water; and then the corresponding washing nozzle with the washing function is controlled to extend outwards.

In this step, the preset cold water discharging time is over, at this time, the driving motor 330 starts to rotate clockwise by 35 °, the movable board 310 starts to switch from the state of fig. 4(b) to the state of fig. 4(c), and in the state of fig. 4(c), the hip washing nozzle 410 and the bidet washing nozzle 420 start to extend outward from the storage state, and since the through hole 311 of the movable board 310 communicates with one end 321d of the groove 321e in the self-cleaning flow path 321 of the fixed board 320, the washing water is sprayed out from the self-cleaning nozzle 430, and the self-cleaning nozzle is located inside the sanitary washing apparatus, and the spraying water is downward and does not spray to the human body. At the same time, the small groove 311a of the movable tray 310, which has a small depth, communicates with the hip cleaning hole 323b of the hip cleaning flow path 323 of the fixed tray 320, and a small amount of water is discharged from the hip cleaning nozzle of the cleaning nozzle unit 400, and further residual cold water in the hip cleaning flow path is discharged. Since the depth of the recess 311a is set to be shallow, the flow rate of the washing water is small, and the washing water does not contact the private parts of the human body during the extension of the buttocks nozzle.

At S4, when the washing nozzle corresponding to the washing function reaches the target position, the movable plate of the distribution valve is controlled to rotate to the washing flow path corresponding to the washing function, and the water jet washing is started.

In this step, when the hip washing nozzle is extended to the shift position selected by the user, and the dispensing valve 300 is driven by the motor 330 to rotate about 55 ° counterclockwise as shown in fig. 5 for the washing nozzle unit 400, the movable panel 310 starts to switch from the original point shown in fig. 4(c) to the state shown in fig. 4(d), and in the state shown in fig. 4(d), the through hole 311 of the movable panel 310 is communicated with the first washing groove 323a of the first washing flow path 323 of the stationary panel 320, so that the washing water is sprayed from the hip nozzle 410 of the washing nozzle unit 400, and thus, the cold water discharging stage is completed, and the hip washing nozzle starts to be continuously sprayed to the private parts of the human body for a predetermined washing time.

The utility model provides a distribution valve and a sanitary cleaning device, wherein a first cleaning flow path, a second cleaning flow path and a self-cleaning flow path are arranged on a fixed disc of the distribution valve, and a first groove and a second groove which are respectively used for communicating the first cleaning flow path and the second cleaning flow path are arranged on two sides of a through hole on the movable disc, so that not only can two functions of flushing be realized, but also residual water on the cleaning flow paths can be drained before cleaning, and the comfort of a user is improved.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
