Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a toilet seat with a hot water bidet that prevents cold water from being sprayed during the initial stage of cleaning.

[Conventional technology] In addition to its main purpose of cleaning the private parts, warm water flushing toilet seats have recently been recognized to have various effects by promoting blood circulation in the private parts and stimulating the autonomic nervous system through pressure stimulation by hot water jets. However, one of the problems is that during the initial cleaning stage, cooled residual water remaining in the piping system is sprayed out, causing discomfort to the user, and various attempts have been made to solve this problem. Ta.

One such method is shown in FIG. 6 as an attempt to drain cooled residual water prior to washing the body's private parts.

This one has a cleaning nozzle 6 at the tip of the piston rod 14.
is provided, and the piston rod 14 is housed in a cylinder 15 when not in use.

In the initial stage of cleaning, cleaning water flows into the cylinder 15 from the pipe 12 via the water inlet 13, pushes out the hollow piston rod 14, and causes the cleaning nozzle 6 to protrude.

At this time, a part of the cleaning water passes through the gap 16 between the piston rod 14 and the cylinder 15, is ejected from the nozzle cleaning port 17, and is injected toward the cleaning nozzle 6.
to self-clean.

When the piston portion 14a of the piston rod 14 reaches the vicinity of the nozzle cleaning port 17, the nozzle cleaning port 17 is closed by the packing 18, and the nozzle cleaning jet stops.
The cleaning water passes through the hollow part of the piston rod 14 and is jetted out from the cleaning nozzle 6.

When the supply of cleaning water from the pipe 12 is stopped, the piston rod 14 is housed inside the cylinder I5 due to the elastic force of the spring 19.

In the above configuration, the piping 12 on the upstream side of the cylinder 15
The cooled residual water in the water heater upstream of the nozzle 6 is discharged for self-cleaning of the cleaning nozzle 6 prior to cleaning the body parts.

Another method is to preheat the residual water in the water heater even when it is not in use.

[The problem that the invention tries to solve! ] However, in the above-mentioned prior art hot water washing toilet seat, in the former case, most of the supplied washing water is stored in the cylinder 15 at the initial stage of washing, and the piston rod 1
4, and the amount of water discharged from the nozzle cleaning port 17 is very small, and as a result, it is not possible to completely prevent cold water injection in the initial stage of cleaning.

In addition, in the latter case, it is necessary to constantly turn on electricity to the water heater to heat the residual water, which raises the problem of high running costs.Furthermore, even if the residual water in the water heater can be heated, downstream This included the problem that water remaining in pipes etc. could not be preheated.

The present invention has been made in view of the problems of the prior art described above, and its purpose is to provide a warm water washing toilet seat that does not perform preheating and prevents cold water from being sprayed in the initial stage of cleaning.

[Means for Solving the Problems] To achieve the above-mentioned object, the warm water-cleaning toilet seat of the present invention has the following features:
In the initial stage of cleaning, the cleaning nozzle is self-cleaned for a predetermined period of time, and at the same time as the cleaning nozzle starts self-cleaning, the water heater starts heating, and the temperature of the cleaning water is sequentially controlled. It is something.

[Operation of the Invention] The operation of the warm water-washing toilet seat of the present invention is that since self-cleaning of the cleaning nozzle is performed at the initial stage of cleaning, a large amount of residual water on the downstream side in the heater of the water heater and residual water in the cold piping is removed. It is discharged in a short time.

[Example] An example of the warm water washing toilet seat of the present invention will be described based on the drawings.

FIG. 1 to FIG. 4 show an embodiment of the warm water washing toilet seat of the present invention.

As shown in the figure, this example includes a low tank 1 as a water supply source, a water suction pipe 2, a pressure pump 3, and a water heater 5.
, a cleaning nozzle 6 , a driving device 18 for the cleaning nozzle 6 ,
a reflecting plate 26 that reflects water jetted from the cleaning nozzle 6;
In the initial stage of cleaning, the cleaning nozzle 6 is moved under the reflection plate 26 and self-cleaned for a predetermined period of time, and the controller 11 starts heating the water heater 5 at the same time as the cleaning nozzle 6 starts self-cleaning. has been done.

As shown in FIG. 3, the drive device 1 is composed of a motor 24, a reduction gear 25, a wire drum 23, a pulley 21, and a wire 22. As shown in the figure, the outer casing 2
A cleaning reflection Fi 26 integrated with the filter 7 is disposed.

The operation of the warm water washing toilet seat of the present invention will be explained below.

In this example, by operating the pressure pump 3, water stored in the low tank 1 is suctioned and pressurized through the water suction pipe 2, passes through the water supply pipe 4, and is heated by the water heater 5 to adjust the temperature to an appropriate temperature. and is sprayed from the cleaning nozzle 6.

FIG. 2 shows a cross section of the water heater 5, and the heating tank 8 is
It has a heating heater 7 in which a heating surface 7a is arranged on the outer surface of a cylinder, and a temperature detection sensor 10 near the heating water outlet 9 detects the temperature of the heated water, and a control unit 11 controls the heating heater 7.
is controlled.

The cleaning nozzle 6 has a hollow loft 20 as shown in FIG.
The cleaning water from the water heater 5 is injected from the cleaning nozzle 6 through the hollow iron 20.

Here, the hollow iron 20 is fixed to a wire 22 wound around two boots 17-21, and is driven in the axial direction as the wire 22 moves.

This wire 22 is wound around a wire drum 23,
The wire drum 23 is rotated via the reduction gear 25 by the operation of the motor 24, the wire 22 is actuated, the hollow rod 20 fixed thereto is driven in the axial direction, and the cleaning nozzle 6 disposed at the tip thereof is moved. It is configured so that it can be done.

FIG. 5 shows a control sequence by the control section 11 at the initial stage of cleaning in this example.

When the cleaning operation is started by the user's operation, the cleaning nozzle 6 is moved to a position directly below the cleaning water reflecting plate 26 as shown in A in FIG. 4 by the operation of the nozzle driving section. In this state, the pressure pump 3 is activated, and at the same time, the water heater 5 is activated to start heating the cleaning water. Most of the residual water remaining in the system is pushed out by the heated cleaning water, and is used for self-cleaning of the cleaning nozzle 6 before being discharged.

Once the residual water has been discharged, the heating bomb 3 and the water heater 5 are stopped, the supply of washing water is stopped, and the washing nozzle 6 is stopped.
is the position of local washing by the drive device 18, that is, the fourth position.
It is projected to position B shown in the figure.

This is to prevent the washing water from being sprayed onto parts other than the private parts of the body while the washing nozzle 6 is moving.

When the cleaning nozzle 6 reaches the position B in FIG. 4, the pressure pump 3 and the water heater 5 are activated again, and the cleaning water is sprayed to the private parts.

In this way, the residual water on the downstream side in the heater of the water heater,
Also, since a large amount of residual water in the cooled pipes is discharged in a short time, the amount of self-cleaning water is abundant and the cleaning nozzle can be cleaned efficiently.

Note that the position of the cleaning nozzle 6 can be freely controlled by controlling the rotation of the motor 24, and although a stepping motor is used here, a position detection feedback device such as a potentiometer or a photointerrupter can also be used. It may be controlled by

[Effects of the Invention] According to the hot water washing toilet seat of the present invention, since the washing nozzle self-cleans with the cooled residual water in the cooled piping at the initial stage of washing, the water heater is not heated when not in use. It is possible to provide a warm water flushing toilet seat that prevents cold water from being sprayed in the initial stage of flushing without preheating.

Moreover, preheating is not required, which is economical.
