Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an improvement of a hot water washing device for a toilet bowl.

(Prior art and its problem) Conventionally, in the toilet bowl 1 shown in FIG. 2, the low tank 5 is erected at the rear part of the toilet body 2, and the service tank 17 is provided from the water stop plug 15 of the low tank through the ball tap 16. The water introduced into the hot water tank 7 is introduced into the hot water tank 7 installed at the bottom of the toilet body 2 via the water supply hose 18, and is heated to an appropriate temperature via the heater 8 and the thermistor 9 in the hot water tank 7 to obtain the optimum temperature. The cleaning water heated to the cylinder 12 is delivered to the cylinder 12 via the electromagnetic pump 10, and the cleaning nozzle 13 in the cylinder 12 is projected forward by the pressure of the delivered cleaning water to eject the cleaning water from the tip. A hot water washing device 6 is formed by the hot water tank 7, the electromagnetic pump 10, the cylinder 12 and the washing nozzle 13. Reference numeral 14 in the drawing is a solenoid for adjusting the angle of the cleaning nozzle 13.
Further, 11 is a branch pipe, 3 is a toilet seat, 4 is a toilet lid, and 20 is an operation panel.

In such a conventional toilet bowl hot water cleaning device, the cleaning water is delivered from the electromagnetic pump 10 to the cleaning nozzle 13, and since the electromagnetic pump 10 has a structure for delivering the cleaning water in a reciprocating manner, it is not delivered. There is a problem in that the cleaning water to be generated becomes a pulsating flow, the cleaning water ejected from the cleaning nozzle 13 spreads, and water droplets scatter.

In order to solve such a problem, conventionally, an accumulator consisting of a rubber hose or the like is provided between the cleaning pump 10 and the cylinder 12, and this accumulator prevents pulsating flow.However, the conventional accumulator is made of rubber and is durable. There was a risk that it would be damaged due to poor performance due to long-term use, and water would leak from this part.

(Means for Solving the Problems) The present invention has been devised in view of the above conventional problems, and an object thereof is to not provide a hot water washing device capable of favorably reducing the pulsating flow of washing water. The gist of the invention is a hot water washing device for a toilet bowl, which sends washing water heated in a hot water tank to a washing nozzle through an electromagnetic pump and ejects the washing water. That is, it has a built-in accumulator mechanism to reduce the number.

(Function) The electromagnetic pump has a built-in accumulator mechanism. When the electromagnetic pump is actuated to deliver cleaning water, this accumulator mechanism reduces the pulsating flow to clean the rectified water from the electromagnetic pump. Will be sent to the nozzle,
The splashing and spreading of the washing water ejected from the washing nozzle is prevented.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a cross-sectional configuration diagram of the electromagnetic pump of this embodiment. In the figure, an intake hole 21 connected to the hot water tank 7 is formed on the left side of the electromagnetic pump 10 on the right side of the intake hole 21. Is provided with a suction valve 21a, and a piston 24 and a plunger 25 are provided inside the electromagnetic pump 10 via springs 22 and 23 so as to be slidable in the left and right directions. A coil 28 is arranged on the surface via an iron core 27. A discharge hole 29 is formed on the right side of the drawing, and the cylinder 12 is connected to the discharge hole 29.

In this example, an accumulation mechanism 30 is built in the inner wall surface on the side of the discharge hole 29, and this accumulation mechanism 30 has a diaphragm 30a made of rubber or the like, and the air chamber E is inside thereof.
Are formed.

In such an electromagnetic pump 10, by exciting the coil 28, when the piston 24 and the plunger 25 are moved leftward in the drawing, the discharge valve 26 interposed between the piston 24 and the plunger 25 is Opening wash water is made to flow in the right direction in the figure, and the electromagnetic coil 28 is demagnetized, so that the spring
The urging force of 22,23 moves the viston 24 and the plunger 25 to the right to compress this cleaning water and discharge the cleaning water from the discharge hole 29. The cleaning water compressed at the time of this discharge is the diaphragm. When the piston 24 and the plunger 25 are moved to the left side in the drawing again, the diaphragm 30a returns to its original shape and the piston 24
Also, the diaphragm 30a vibrates as the plunger 25 reciprocates, and the pulsating flow of the cleaning water discharged from the discharge hole 29 is favorably reduced, and the pulsating flow of the cleaning water delivered to the cylinder 12 and the cleaning nozzle 13 is reduced. Will be rectified. Therefore, the washing water ejected from the washing nozzle 13 has no pulsating flow, little scattering of water, etc., and the water does not spread, and it can reach the local area of the user well and improve the washing effect. it can.

A diaphragm is provided in the air chamber E of the accumulation mechanism 30.
A spring or the like for pressing 30a to the left side in the drawing may be incorporated,
In such a structure with a built-in spring, the diaphragm
The restoring force of 30a is improved, and the occurrence of pulsating flow can be further reduced.

As described above, in this example, since the accumulation mechanism 30 is provided inside the electromagnetic pump 10, the diaphragm 30 is deteriorated due to deterioration or the like.
Even if a breaks, the wash water does not leak out of the path, and the risk of electric shock is well prevented.

(Effects of the Invention) The hot water washing device of the present invention is a hot water washing device for a toilet bowl, which sends the washing water heated in a hot water tank to a washing nozzle through an electromagnetic pump to eject the washing water. The built-in accumulator mechanism that reduces the pulsation flow of the washing water, the pulsation flow generated when the electromagnetic pump delivers the washing water is well reduced by the accumulation mechanism, and the scattering of the washing water spouted from the washing nozzle. In addition, there is an effect that a good local cleaning function can be exhibited without spreading.

Also, because the accumulation mechanism is built into the electromagnetic pump,
The structure is simple, and there is no concern about branch pipes, and there is no risk of water leakage.
