Next, a method for controlling the fluid in the bidet nozzle unit according to an embodiment of the present invention will be described in detail with reference to FIG. 6 . 6 is a flowchart illustrating a method for controlling fluid discharge from a bidet nozzle unit according to an embodiment of the present invention.

First, the nozzle unit washing water discharge command is input to the manipulation unit 300 (S61). The washing water discharge command may include a high pressure washing water discharge command and a low pressure washing water discharge command.

Next, the power supply unit 700 applies an electric signal to the DC motor 542, and the DC motor 542 rotates according to the applied electric signal to extend the nozzle unit 500 (S62).

Given after the delay time has elapsed, the nozzle cleaning unit latch valve (V ₂₎ electrical signal is applied, the nozzle cleaning unit latch valve (V ₂₎ is opened the to the inlet 21 and the second outlet (23) first to the They communicate with each other (S63). This is to prevent the washing water from being discharged due to excessive water pressure when the user initially operates the bidet.

In this case, the raw water introduced into the inflow passage 21 may be discharged to the outside of the nozzle washing unit 533 through the second outflow passage 23 , and since the second outflow passage 23 is filled with raw water, thereafter Even if the nozzle part latch valve (V ₁ ) is opened, the problem that raw water is not properly discharged due to negative pressure can also be solved.

Given after the delay time has elapsed, the nozzle unit the latch is an electrical signal and the valve (V _1), the nozzle unit latch valve (V ₁₎ is opened 22 to 21 and the first outlet to the inlet is in communication with each other (S64).

The raw water introduced into the inflow passage 21 may be discharged to the outside of the nozzle unit 500 through the first outlet passage 21 , and at this time, the raw water introduced into the inflow passage 21 is mixed with the nozzle unit 500 and Since it is discharged to the outside through all of the nozzle washing units 533 , the water pressure of the washing water discharged through the nozzle unit 500 may be lower than the command input to the manipulation unit 300 . However, when the high pressure washing water comes in contact with the user's local or anus, it may cause discomfort to the user, and there is a risk of injury to the user's local or anus, which is a sensitive area. One problem can be solved.

Next, a step of determining whether the nozzle unit washing water discharge command input to the manipulation unit 300 is a high pressure washing water discharge command or a low pressure washing water discharge command is performed (S65).

When the nozzle washing water discharge command input to the operation unit 300 is a low-water pressure washing water discharge command, first, after a predetermined delay time has elapsed after step S64, an electrical signal is applied to the _{nozzle washing unit latch valve V 2 ,} The nozzle cleaning unit latch valve (V ₂ ) is closed (S67). In another embodiment, the nozzle cleaning unit latch valve as is not applied to the additional electrical signal in the (V _2), the open state of the elastic member (not shown) by a method using such a nozzle cleaning unit latch valve (V ₂₎ is released It is also possible that the closing of the nozzle cleaning unit latch valve (V _{2 ) through being.}

When the nozzle washing unit latch valve (V ₂ ) is closed, the raw water introduced into the inflow path 21 may be discharged to the outside of the nozzle unit 500 only through the first outlet path 22, specifically, Raw water introduced into the inflow path 21 may pass through the first opening 25a of the body member 25 and may be discharged to the outside of the nozzle unit 500 through the passage of the connection member 26 . Accordingly, the user can perform local or anal cleaning according to the intended water pressure.

When the nozzle part washing water discharge command input to the operation unit 300 is a high pressure washing water discharge command, after a predetermined delay time has elapsed after step S64, an electrical signal is applied to the flow _{rate control part latch valve V 3 to control the flow rate} The sub latch valve V ₃ is opened (S66), and after a predetermined delay time has elapsed, similarly to the low water pressure washing water discharge command, the nozzle cleaning unit latch valve V ₂ is closed (S67).

When the flow control unit latch valve (V ₃ ) is opened, the raw water introduced into the inflow passage 21 also flows into the bypass passage 24 , and the nozzle unit 500 up to the raw water introduced into the bypass passage 24 . Since it can be discharged through the Specifically, raw water introduced into the inflow passage 21 passes through the first opening 25a of the body member 25 , and raw water introduced into the bypass passage 24 through the second opening of the body member 25 . Passing through (25b), they may be discharged to the outside of the nozzle unit 500 through the passage of the connecting member (26). Accordingly, the user can perform local or anal cleaning according to the intended water pressure.

The control method according to an embodiment of the present invention described above may be implemented in the form of a program command that can be executed through various computer means and recorded in a computer-readable medium. The computer-readable medium may include program instructions, data files, data structures, etc. alone or in combination.
