Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a sanitary cleaning device that can clean private parts hygienically and comfortably.

Conventionally, sanitary cleaning devices for cleaning private parts of the human body have a spouting part on the underside of the toilet seat, and this spouting part is equipped with a telescopic nozzle that moves forward and backward in the direction of the toilet bowl, and heat is generated from the spout hole drilled at the tip of the telescopic nozzle. The structure is such that cleaning water can be jetted out to perform cleaning.

Since the telescopic nozzle advances toward the toilet bowl during cleaning, dirt may adhere to it, and if it is not used for a long period of time, dirt and dust may adhere to it, and it is extremely unsanitary to clean it as it is. To deal with this, in conventional systems, a separate nozzle cleaning piping is provided to clean the nozzle itself, and the valve in the piping system is opened to perform nozzle cleaning; Manually opening the valve each time it is used is troublesome and has the drawback of being inconvenient to use.

The present invention aims to solve the above problems.
By configuring the extensible nozzle to be automatically cleaned when cleaning is completed, the purpose is to keep the nozzle part clean at all times and to perform sanitary cleaning.

Hereinafter, the present invention will be specifically described based on an embodiment shown in the accompanying drawings.

(25) is fitted into the cylindrical body (20) and has an inner diameter larger than the outer diameter of the pipe (22) by the required amount.
22) A nozzle camp that can define an annular flow path (F2) between the nozzle camp and the outer peripheral surface.

The nozzle cap (25) is provided with a recess g (25a) on one end side, and the cylinder (20) has a protrusion at a required position and protrudes inward at the upper part of the cylinder (20). Part (20
a) is formed. Therefore, in this example, the nozzle camp (
25) is made of ABS resin, etc., so the installation of the camp (25) requires the turning pressure (25a) and the protrusion (25).
By fitting 0a), it can be made detachable and can be attached at the correct position. Furthermore, (26) is a seal gasket provided at a required position between the connecting fitting (21) and the nozzle cap (25). In the combination of the cylindrical body (20) and the nozzle camp (25) connected by the above-mentioned fitting, for example, five large first ejection holes are arranged so as to communicate with the first inlet (23) via the pipe (22).

Figures 11 and 12 show water heating equipment (5) from water pipes.
Flowchart for washing water in the case of a direct water supply system that supplies water directly to the water supply, and from the washing water tank (2) to the water supply heating device (5
) shows a flowchart for indirect water supply. In the one in Figure 11, the flow path branches in two directions from the water supply source (i.e. water pipe) 0 to the wash water tank (2) and the feed water heating device (5), and the required strainer, check valve and solenoid valve ( Water flows into the feed water heating device (5) through the water heater (VM), and within the feed water heating device (5), it passes through a pressure regulating valve to adjust the flow rate, goes to the hot water storage tank, and is directly discharged through a throttle valve. It is divided into two routes. The cleaning water that reaches the hot water storage tank is heated by a heater, passes through a vacuum breaker to prevent backflow, and then reaches the nozzle body (6C) and the telescopic nozzle (6d) from the elbow (6j) and is discharged. Also, the cleaning water that does not flow into the hot water storage tank is discharged through a throttle valve and a vacuum breaker, but this discharged water is discharged through a drain (D) that has a discharge port in a part of the cover (6b) of the nozzle body (6C). .

In addition, in Fig. 12, water is supplied from the wash water tank (2) to the feed water heating device (5) through the feed pipe (8), and the water is stored using the electromagnetic pump (P) built into the device. The water is sent into the tank and is spouted from the telescopic nozzle (6d) of the spouting part (6).

Hereinafter, the washing water 1 discharge in the case of direct water supply shown in FIG. 11 will be described. The flushing water is discharged by opening a solenoid valve (7M), and the opening/closing operation of this solenoid valve (VM) is performed using a magnet (M), each reed switch (S+),
(S2), (S3) and telescopic nozzle (6d
), and the motor (6e) is similarly turned on and off as appropriate based on the position detection of the telescopic nozzle (6d).

A part of the controller (C2) that controls the on-off valve of the solenoid valve (VM) and the drive of the motor (6e) and its forward and reverse rotation is built into the feed water heating device (5). Control by the above-mentioned telescopic nozzle (6d)
This is done in response to a signal from position detection and a condition signal indicating whether it is anal cleaning or bidet cleaning from the cleaning switch (5b) of the operating section (C1). Figure 13 shows the control of the controller part (C2). The circuit and Fig. 14 show the solenoid valve (VM) and motor (
A time chart of 6e) is shown, and the cleaning process will be explained below based on the same figure.

2. First, when the cleaning switch (5b) is turned on to the anal cleaning side (time: to), the motor (6e) simultaneously communicates and rotates, the leaf spring (6f) expands, and the telescopic nozzle (6d) advances. When the magnet (M) reaches the reed switch (S2) position, the control unit receives a signal from both of them and the motor (6e) stops (time: t).

Next, a part of the controller receives a signal from the correspondence between the magnet (M) and the reed switch (32), and the above-mentioned time 1. At this point, the solenoid valve (VM) turns on and opens, and the ejection part (6
) is supplied with hot water heated in the hot water tank. In this case, as described above, by adjusting the stroke of the telescopic nozzle (6d), the position Ll in FIG. 2 is reached and the second inlet (23) is reached.
communicates with the elbow (6j) on the water supply side via the communication path (6k) and the annular recess (6β), and the solenoid valve (VM
) are opened at the same time as described above, so that cleansing water at a comfortable temperature flows down from the hot water tank and is discharged from the second spouting hole (28) to clean the anus. After cleaning is completed, if the cleaning switch (5b) is turned off (3 time: t2), the solenoid valve (VM) closes and discharge stops, and at the same time, the magnet (M) and reed switch (S2) are turned off.
A part of the controller receives a signal from the motor (6
e) is reversed, the telescopic nozzle (6d) moves to the storage position, and along with this movement, the magnet (M) and reed switch (
When S+) responds, the motor (6e) stops and (
Time: t3) The telescopic nozzle (6d) is the nozzle body (6c)
will be stored in. At time t3, the solenoid valve (VM) opens again to supply water to the nozzle body (6C), and this water flows from the annular flow path (61) to the second gasket (P2) as described above.
and flows outward from the gap (G) between the flat part of the nozzle camp (25). Therefore, the nozzle camp (25) can be cleaned by the flow of water from this annular recess (61). Then, at time t4 after the required time (1 to 2 seconds) has passed, the solenoid valve (
VM) is closed and one cleaning process is completed.

On the other hand, in the case of bidet cleaning, turn on the cleaning switch (5b) to the bidet cleaning side, which causes the telescopic nozzle (6
d) is extended, but in this case, due to the configuration of the control 4 circuit, the magnet (M) can be extended until it corresponds to the reed switch (S3). Entrance (23)
When the solenoid valve (VM) is opened, cleaning water is jetted out from the first jet hole (27) and cleaning can be performed.After the cleaning is finished, the cleaning switch (5b) is turned off to perform the above operation. Similarly, magnet (M) and reed switch (S+'
), the telescopic nozzle (6d) can be stored.

Similarly, cleaning of the nozzle cap (25) portion after cleaning can be performed by the controller part (C2).

The above example is for direct water supply, but when using an electromagnetic pump (P) for indirect water supply, the operation of this electromagnetic pump (P), that is, the timing of its start and stop, is the opening and closing of the electromagnetic valve (VM). , respectively, and the telescopic nozzle can be similarly cleaned after cleaning is completed.

Furthermore, in the above example, the telescopic nozzle (65 d) is cleaned when the telescopic nozzle (65 d) is stored after private washing, but it is also possible to wash the nozzle (65 d) before extending it and after storing it. The control circuit and time chart I. are shown in FIGS. 15 and 16.

When the cleaning switch (5b) is turned on ζ (time = to), the solenoid valve (VM) opens (starts in the case of the solenoid pump (P)), cleaning water is supplied, and it is in the storage area. The nozzle camp (25) part of the telescopic nozzle (6d) is cleaned, and after a predetermined period of time, the solenoid valve (VM) closes (stops when using the solenoid pump (P)), and from then on, the time chart described above ( The same operation as in Fig. 14) is performed, and when the telescopic nozzle (6d) is retracted after cleaning the private part, the telescopic nozzle (6d) is cleaned again. Therefore, in this case, cleaning of the telescopic nozzle (6d) can be performed twice at the start and end of one cleaning.

As described above, according to the present invention, it is possible to automatically clean the spouting part of the telescopic nozzle that is closest to the private part when cleaning the private part, so the jetting part can always be kept clean, resulting in hygienic private parts cleaning. There are 6 effects:
