Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention expands the cleaning range by swinging the jet stream ejected from a cleaning nozzle onto the user's area to be cleaned, thereby providing a more comfortable cleaning effect. The present invention relates to a sanitary cleaning device that provides the following.

2. Description of the Related Art Conventionally, the cleaning means of a sanitary cleaning device was to impinge a jet stream from a cleaning nozzle fixed at an appropriate position onto a user's part to be cleaned at a substantially fixed position. In this conventional sanitary washing device, the heater capacity is a constraint for those that use an instant heating method as the washing water heating method, and the tank capacity is a constraint for those that use a hot water storage method.The flow rate that can be ejected from the washing nozzle is 0.5e/mln. From 17 at most? /min
I was only able to give out a certain amount. In order to obtain a sufficient cleaning effect with this level of cleaning flow rate, it is necessary to determine the jet diameter of the jet nozzle of the cleaning nozzle, the number of jets, and the spacing between the jets if multiple jets are provided. This was an important point for conventional cleaning nozzles. However, since the absolute value of the cleaning flow rate is small, it is extremely difficult to balance the cleaning range and cleaning intensity with fixed nozzles.

In addition, as a method of improving the drawbacks of such conventional fixed nozzles, there is a method of using a fluid element in the jet jetting part of the cleaning nozzle to swing the jet within a certain range. In this method, the cleaning jet oscillates at almost constant intervals, so the cleaning effect is higher than with a fixed nozzle, but it is difficult to change the amplitude of the oscillation, so people who want a strong cleaning feeling (In this case, the flow rate is large, so it is necessary to narrow the oscillation width to prevent washing water from splashing.) In response to the needs of people with hemorrhoids, who require weak cleaning strength but a wide cleaning range. I was unable to respond.

Problems to be solved by the invention In order to mechanically swing the cleaning nozzle to expand the cleaning range and obtain a more comfortable cleaning effect, the problems are as follows: (1) The user can adjust the swing range of the cleaning nozzle. Provide adjustment means to enable this.

(2) Set the maximum value of the washing flow rate according to the washing range to prevent washing water from scattering.

It is.

Means for Solving the Problems In order to solve the above problems, the present invention provides a cleaning nozzle swinging mechanism in which the amplitude of the swinging of the washing nozzle is variable, and a cleaning nozzle swinging mechanism in which the amplitude of the swinging by this swinging mechanism is adjustable by the user. It is equipped with an adjustment means that can be controlled by body sensation. In addition, there is a function to set the maximum washing flow rate according to the swing range, and a switch between hard washing and soft washing as a washing mode setting. It is also effective to solve the above problems by adding a function that allows elderly and children to select with a single touch, such that the cleaning range is wide during ~strong level and soft cleaning, and the water pressure is from weak to medium level.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 6. In the figure, 1 is a toilet bowl, 2 is a flushing water tank connected to the rear of the toilet bowl, and 3 is a flushing toilet seat unit connected to the toilet bowl 1, including a hot water heating section, a pressurizing section, a cleaning section, and controls for controlling these. The toilet seat 4 and the toilet lid 5 are rotatably connected to each other. A jet jetting part 6 that jets cleansing water onto the area to be cleaned of a user seated on the toilet seat 4 is located at the tip of an extendable part 7a of a nozzle 7, and is configured to appear and retract from the cleansing toilet seat unit 3. Cleaning water tanks 2 and 6 are connected to the cleaning toilet seat unit 3 through a water supply pipe 8, and are further communicated to a pump 8 & in the cleaning toilet seat unit 3. The water pressurized by the pump 8a reaches the hot water supply section 10 via the discharge flow path 9. The hot water supply section 10 includes a hot water tank 13 having an inlet pipe 11 and a hot water outlet pipe 12, a sheathed heater 14 built in the hot water tank 13, a temperature sensor 15 that detects the Par of the hot water tank 13, and a control section 16.
The input to the sheathed heater 14 is controlled so that the water temperature is at an appropriate temperature. The field heated by the hot water supply section 10 is
The hot water outlet pipe 12 leads to a water stop valve 17 . The water stop valve 17 has a closing function against the differential pressure caused by the difference in height between the wash water tank 2 and the wash toilet seat unit 3, and when the pump 8& is activated and high pressure is generated, the valve opens and the nozzle 7 is closed. It communicates with the connection port 18 and functions like a kind of pressure relief valve.

The nozzle 7 is equipped with an extensible part 7a that moves in and out by water pressure, and a swinging means 20 that is driven by a motor 19.

The swinging means 20 detects the back and forth swinging of the nozzle 7 by a link mechanism 21, the left and right swinging by a guide means 22 that restricts movement around the axis of the nozzle 7, and the position of the nozzle 7 in the back and forth direction. 1, the link mechanism 21 is composed of a position detecting means 23, which is a pair of fixed links 24a, 24b provided integrally with the nozzle 7, and is sandwiched between the pair of fixed rings 24a, 24b, so that the nozzle 7 can be freely rotated ( A pair of shafts 26a, 26b provided on the rotary ring 25 are supported by a pair of bearings 28a, 28 provided on an arm 27 driven by the motor 19.
The driving part of the link mechanism 21 configured to be rotatably inserted into the substrate 3 and the nozzle guide 29 that holds the nozzle 7 slidably in the axial direction in order to support the movement of the nozzle 7 are attached to the substrate 3.
0''-, and is fixed rotatably in the direction of movement of the nozzle 7. Further, the guide means 22 for regulating the movement around the axis of the nozzle 7 is composed of a guide pin 31 fixed to the nozzle kite 29 and a bin guide 33 having a groove cam 32 guided by the guide pin 31. 32 is constituted by a wavy groove so that the nozzle 7 moves a predetermined distance left and right with respect to the direction of reciprocating motion. The shape allows for smooth movement inside. Position detection means 2
3 is a magnet halter 3 provided on the same 1i11+ as the arm 27
4 and a plurality of magnetic sensors 37 installed on a detection plate 36 installed close to the magnet 35.
It becomes more.

Next, regarding the operation during cleaning, when the user turns on the cleaning switch (not shown), the pump drive circuit 42 (
Pump 8I set to the flow rate which is the flow rate adjustment means)! 1
The skewer in the hot water tank 13 is fed to the nozzle 7 under pressure. The hot water that has flowed into the nozzle 7 pushes out the extensible part 7a of the nozzle 7 to a predetermined position, and then is ejected from the jet jet part 6 onto the part to be cleaned by the user. At the same time, the nozzle 7 is moved to the swinging means 2.
0 causes the user to swing back and forth and left and right. Furthermore, regarding this back and forth rocking, the basic amplitude of the rocking is determined by a position detection circuit 38 into which signals are input from a set of magnetic sensors 37, and the constant of the delay circuit 39 is determined by the user using the operation unit 40. Step 9 - 7 By adjusting the delay time, the drive time of the motor drive circuit 41 of the motor 19 can be changed, and the amplitude of the swing of the nozzle 7 can be changed. It is also possible to move the center of swing by switching the combination of magnetic sensors 37 used for position detection.

According to the above configuration, by using at least seven sets of magnetic sensors 3, it is possible to adjust the amplitude of the swing of the nozzle 7 in accordance with the user's sensation.

Next, a second embodiment of the present invention will be described using FIG. 7.

The difference in FIG. 7 from the previous embodiment is that a constraint condition linked to the flow rate ejected from the jet jet section 6 of the nozzle 7 is added to the means for changing the swing amplitude of the nozzle 7. Specifically, the maximum value of the swing width according to the ejection flow rate set by the pump drive circuit 42 is set in the constant setting circuit 43 so that it becomes smaller as the ejection flow rate increases, and this condition is satisfied. A swing control section 44 is provided which sets a delay time to the motor drive circuit 41 using a delay circuit 39 and determines the swing width.

According to the above configuration, the upper limit of the oscillation width of the nozzle 7 or the jetting flow rate is set to become smaller as the flow rate of the cleaning jet increases (according to the flow rate of the cleaning jet). Even if the cleaning jet is not sprayed, the cleaning jet will not scatter, providing a comfortable feeling of use.

Next, a third embodiment of the present invention will be described using FIG. 8. The difference in FIG. 8 from the second embodiment is that a cleaning mode switching means 45 having an operating section 40a that allows one-touch switching between two types of cleaning modes is provided. When hard cleaning is selected with the operation unit 40a, the delay circuit 39 sets the swing range to be narrow, and the pump drive circuit 42 sets the jet flow rate to be relatively large. Therefore, a powerful cleaning feeling can be selected with one touch with little splashing. In addition, when soft cleaning is selected with the operation unit 40a, the delay circuit 39 has a wide swing range, and the pump drive circuit 42 has a relatively small ejection flow rate.
This is set. In this case, since the Shokawa flow rate is relatively small, the cleaning effect of the jet alone is small, but since the oscillation range is wide, a sufficient cleaning effect can be obtained with a soft cleaning feeling.

The above configuration provides a means to respond to the user's desired cleaning sensation (mainly, those who desire a strong cleaning sensation and those who desire a soft cleaning sensation) with a single touch. It can be used with confidence, especially by elderly people who are not good at complex operations.

Effects of the Invention As described above, the sanitary cleaning device of the present invention provides the following effects.

(1) In addition to providing a means to swing the cleaning nozzle,
It has a function to adjust the range of this oscillation according to the user's experience, so it can be adjusted according to individual differences or physical condition.
The effect of swinging the cleaning nozzle can be fully demonstrated.

(2) As the cleaning flow rate increases, the two-limit value of the swing width of the cleaning nozzle becomes smaller, which suppresses the scattering of the cleaning jet when the cleaning flow rate increases.
You can get a comfortable cleaning feeling.

(3) The combination of cleaning flow rate and swing range can be used in node cleaning mode (flow rate - large, range - small), soft cleaning mode (
Two cleaning modes (low flow rate and large range) are provided, and these can be selected with a single touch, improving operability.
