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 washing devices for cleaning private parts of the human body are equipped with an electromagnetic pump that supplies heated washing water to a spouting section, and a flow rate control valve that adjusts the flow rate of the washing water between the electromagnetic pump and the spouting section. .

Therefore, by manually changing the opening degree of the flow rate control valve, the amount of cleaning water from the jetting part can be adjusted, but if the flow rate is restricted, the load on the electromagnetic pump increases, which may cause the electromagnetic pump to malfunction. It has the disadvantage of poor durability.

Furthermore, due to the piping connection between the flow 111 node valve and the electromagnetic pump, the piping system becomes complicated, and there is also the problem that a compact design cannot be achieved.

The present invention aims to eliminate the above-mentioned drawbacks.
To remove the flow rate control valve from the piping system and configure the flow rate adjustment by controlling the phase of the electromagnetic pump, thereby improving the durability of the electromagnetic pump and simplifying the piping system to enable a compact design. The purpose is to

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

In the figure, (7) is a hot water storage tank that has a sheathed heater that serves as a heater and a temperature sensor that detects hot water temperature, etc. This hot water storage tank (7) is supplied with cleaning water that is connected to the cleaning water tank (2). Washing water flows in from the pipe (8). Cleaning water supply pipe (

A flow path is formed to the second water supply pipe (12) connected to the discharge port of the hot water tank (7). Furthermore, (13) is a hot water storage tank (
This hot water pipe is connected to the upper side of 7).
13) is connected to the ejection part (6).

The spouting part (6) is provided at a portion corresponding to the approximate axis position of the toilet bowl +11, and includes a nozzle body (6a) with a sliding hole penetrating through the interior facing toward the toilet bowl (1a);
The main components include a telescoping nozzle (6b) that is slidable along its axis in the direction of the toilet bowl (la) and has a spout hole at its tip, and an electric motor (6C) that drives the telescoping nozzle (6b) back and forth. It is composed as an element. The hot water pipe (13) is directly connected to the nozzle body (6a), and when the telescopic nozzle (6b) advances and reaches the cleaning position, the hot water pipe (13) and the telescopic nozzle (6
b) The flow path formed in the nozzle is configured to communicate with each other, and the cleaning water is discharged from the jet hole at the tip of the nozzle.

In addition, this example shows the case of a heated toilet seat (3) in which the toilet seat (3) is heated by a heater built into the toilet seat (3), and (0 weight) and (C2) are temperature, hot water temperature joint heated in the hot water tank (7), electromagnetic pump (
11) to adjust the flow rate of the cleaning water, and furthermore, the telescopic nozzle (
This is a control unit that controls all electrical components such as the electric motor (6c) that drives the motor (6b).

In the sanitary cleaning device having the above configuration, the cleaning switch (5b
) is turned on, the telescopic nozzle (6b) reaches the cleaning position by the control unit (CI), (C2) and the electromagnetic pump (11) is activated to discharge water from the cleaning water tank (2) as shown in the flowchart of Fig. 5. As water flows into the hot water storage tank (7), the hot water supply pipe (13
) is fed to the ejection part (6) and ejected from the telescopic nozzle (6b) for cleaning.

The flow rate of the cleaning water is controlled by an electromagnetic pump (11), which is commonly used and generates pressure by intermittent energization of a coil that attracts a plunger in a pipe. (In this example, cleaning water) is of a structure to be transferred.

The flow rate of washing water by the electromagnetic pump (11) is adjusted by controlling the phase of electricity supplied to the pump, and the control circuit thereof is shown in FIG. In the figure, (E) is a power supply, (S) is a switch, (SCR) is a control element, (SB S) is a bidirectional trigger element, (DI) is a diode, and (VR) is a bidirectional trigger element.
+ ) is a variable resistor for flow rate adjustment whose resistance value changes by operating the knob (5C). Furthermore (CI),
(C2), (C3) are capacitors, (R+),
(R2) and (R3) are resistors, and (Ll) is a beam handle.

The operation of the above control circuit is described below.
), the power supply (E), switch (S), electromagnetic pump (11), diode (DI), variable resistor (V
R,), capacitor (CI), reactor (L+)
A current flows in the direction, and the capacitor (C1) is charged.

In this case, the control element (SCR) is cut off because no signal is applied to its gate. The charging voltage of the capacitor (C+) gradually increases based on a function related to the resistance of the circuit and the capacitance of the capacitor (C+). The charging voltage of this capacitor (C+) is connected to the bidirectional trigger element (SBS).
When the trigger voltage of , the control element (SCR) becomes conductive. As a result, power supply (E) - switch (S) →
A circuit of electromagnetic pump (11) - control element (SCR) - reactor (Ll) -> power supply (E) is generated, and voltage is applied to the electromagnetic pump (11) to operate it. On the other hand, the control element (
Due to the conduction of SCR), the charge remaining in the capacitor (cl) is transferred from the capacitor (C+) to the bidirectional trigger element (SBS).
) - resistor (R8) - control element (SCR) -> capacitor (C3). And the control element (
Once conductive (SCR) is turned on, it will not be shut off until the current runs out, so it will remain conductive until the end of the positive half cycle of AC, and will be shut off during the negative half cycle, completing one cycle of operation. It is.

In the above control circuit, the rate of increase in the charging voltage of the capacitor (C,) changes depending on the resistance value of the variable resistor (VR,). Therefore, by changing the resistance value of the variable resistor (VR+), the conduction angle of the control element (SCR) can be changed.
This allows the average power applied to the electromagnetic pump (11) to be changed. By making the average power to the electromagnetic pump (11) variable, the amount of movement of the plunger in the pump, that is, the amount of cleaning water transferred, can be changed, making it possible to adjust the flow rate.

As mentioned above, since it is the variable resistor (VR+) that changes the average power to the electromagnetic pump (11), the knob (5C) on the panel part (5a) is directly connected to the variable resistor (VRi). If configured to be operable, the flow rate of cleaning water can be changed using the same knob (5C), and an appropriate flow rate of cleaning water suitable for each type of cleaning can be selected.

As described above, the sanitary cleaning device according to the present invention has the following effects due to its configuration.

(1) The flow rate of cleaning water spouted from the spouting part can be changed by controlling the phase of the energization to the electromagnetic pump, so there is no need to provide a flow rate adjustment valve downstream of the electromagnetic pump, simplifying the piping system. The structure is simple and a compact design is possible.

(2) Because of the above +11, no throttling due to a flow rate regulating valve or the like occurs downstream of the electromagnetic pump, so the load on the electromagnetic pump is reduced, failures are reduced, and durability can be improved.
