Abstract

PURPOSE:To simplify the structure and to prevent freezing by installing a flow control valve between the operating section of the top face of a body case and a hot water tank and fitting a knob turning a valve stem to the valve stem. CONSTITUTION:A flow control valve 14 adjusting the force of water by rotating a valve stem 16 and controlling the quantity of water fed to a washing nozzle is mounted between an operating section 28 set up onto the top face of a body case 27 and a hot water tank 21. A knob installed to the operating section 28 for rotating the valve stem 16 of the flow control valve 14 is fitted to the valve stem 16. A water path is formed by the shell of the hot water tank 21 and the flow control valve 14. Accordingly, the number of components is decreased, and the flow control valve 14 is warmed and the possibility of freezing can be removed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a sanitary cleaning device for cleaning private parts of the human body.

2. Description of the Related Art Conventionally, this type of sanitary cleaning device has been disclosed, for example, in Japanese Unexamined Patent Publication No. 61-1
As shown in Japanese Patent No. 64383, it has a structure as shown in FIG. In Fig. 5, the main body 1 is directly connected to the water supply, water passes through the copper pipe 2 and enters the pressure reducing valve 3, and when not in use, the hot water is sent to the flow control valve 5, the hot water tank 6, and the cleaning nozzle 7 by the solenoid valve 4. On the other hand, during cleaning, the solenoid valve 4 opens, hot water in the hot water tank 6 is sent to the cleaning nozzle 7, and cleaning water is spouted out. The force of the gushing water.

The flow rate can be changed by adjusting the valve body 8 of the flow rate control valve 5 by turning the knob 9 via the wire 10.

11 Problems to be Solved by the Invention However, with such a structure, the flow rate control valve 5 inside the main body 1 freezes during severe winter weather, causing damage to the parts, impairing the flow rate control function, and causing the cleaning nozzle 7 to fail. There was a fear that the water might change.

The present invention solves the above problems and provides a sanitary washing device having a flow control valve that is not connected even in winter.

Means for Solving the Problems In order to solve the above problems, the sanitary cleaning device of the present invention includes:
A flow control valve that adjusts the water force by rotating the valve stem and controlling the amount of water supplied to the cleaning nozzle is installed between the operation section on the top of the main body case and the hot water tank, and a flow control valve is installed between the outer shell of the hot water tank and the flow control valve. Further, a knob provided on the operating portion to rotate the valve shaft of the flow rate regulating valve is adapted to fit into the valve shaft.

Operation With the above configuration, the flow rate regulating valve is directly heated by using the heat of the hot water in the hot water tank, and is also indirectly warmed through the outer shell of the hot water tank, so there is no fear of freezing. In addition, since the valve shaft of the flow control valve is directly rotated by the knob on the operating section, the number of parts is small and the configuration can be simplified.

Example Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 4 is a diagram for explaining a water circuit in a sanitary washing device according to an embodiment of the present invention. In FIG. 4, 11 is a water supply port connected to a water pipe.

A constant flow valve 12 made of a disc-shaped rubber elastic body having a water passage port in the center is provided inside. 13 is constant flow valve 1
This is a water stop valve (electromagnetic valve) provided on the downstream side of No. 2. Reference numeral 14 denotes a flow control valve provided on the downstream side of the water stop valve 13, which branches the waterway into a main waterway A and a splint channel B, and adjusts the flow rate flowing into each waterway. The flow rate regulating valve 4 includes a valve case 15 having a communication channel 15a to the main channel A and a communication channel 5b to the splint channel B, and a substantially triangular shape that varies the flow rate to the communication sections 15a and 15b. A valve shaft 16 having shaped throttle holes 16a and 16b, and an O-ring 16c that seals each water channel.
The flow rate to the main channel A and the splint channel B can be adjusted by turning a knob 17 connected to the valve shaft 16. 18 is a relief valve, and when the water pressure on the main waterway A side exceeds a predetermined pressure, the relief valve spring 1
8a, the relief valve piece 18b opens, and the sub-channel B
Designed to release excess pressure to the sides. A hot water tank 21 consisting of a tank main body 19 and an upper plate 20 includes a heater 22 that heats water and a hot water temperature sensor 23 that maintains cleaning water at a predetermined temperature. 24 is a cleaning nozzle connected to the hot water tank 21, and 25 is a discharge port provided on the most downstream side of the sub-channel B, which discharges water into the toilet bowl 26.

FIG. 3 is a perspective view of the sanitary cleaning device when the toilet bowl is installed.

In FIG. 3, the main case 27 of the cleaning device is connected to the toilet bowl 26.
An operating section 28 mounted on the shaft of the main body case 27 is provided with a switch 29 for turning on/off the cleaning and a knob 17 for adjusting the flow rate. 30 is a toilet seat, and 31 is a toilet lid which is rotatably attached to the main body case 27.

FIGS. 2(A) and 2(B) are a partially sectional side view and a partially sectional plan view of the sanitary cleaning device, showing the arrangement of each component within the main body case 27. Here, since the numbers assigned to each part are the same as those explained in FIGS. 3 and 4, the explanation thereof will be omitted.

FIG. 1 is an enlarged cross-sectional view of a hot water tank 21 and a flow control valve 14, which are the main parts of a sanitary washing apparatus according to an embodiment of the present invention. In FIG. 1, water that has passed through the water stop valve 13 and entered from the water inlet 32 is transferred to the upper plate 20 of the outer shell of the hot water tank 21 and to the flow control valve 1.
The water is supplied into the hot water tank 21 through a water passage formed by the four-valve case 15 and the valve shaft 16, and further through the water supply pipe 33. Further, the cylindrical rib 34 on the upper part of the valve case 15 is fitted into a groove 35 provided in the main body case 27, making it easy to center the knob insertion hole 36 provided in the main body case 27 and the valve shaft 16. Easier to assemble. Furthermore, even if water enters through the knob insertion hole 36, the groove 35 of the main body case 27 fits into the rib 34 of the valve case 15, so that water will not enter the inside of the main body case 27.

Next, the operation of the above configuration will be explained. The water in the hot water tank 21 is heated by the heater 22.

Approximately 40
The water is heated to ℃. The flow rate control valve 14 is connected to the hot water tank 2
The outer shell of the hot water tank 21 constitutes a water passage and communicates with the inside of the hot water tank 21, and the flow rate regulating valve 14 is heated directly by the hot water in the hot water tank 21, and also indirectly heated by the hot water from the outer shell of the hot water tank 21. warmed by.

Further, the flow rate control valve 14 is provided between an operating section 28 provided on the upper surface of the main body case 27 and the hot water tank 21, and a knob 17 of the operating section 28 is directly inserted into the valve shaft 16. By turning the valve stem 16, the water force of the cleaning nozzle 24 can be changed.

Effects of the Invention As described above, according to the present invention, the following effects can be achieved by providing the flow rate regulating valve between the operating section on the upper surface of the case and the hot water tank and attaching it to the outer shell of the hot water tank.

(1) With a simple configuration, the flow control valve can be warmed using the heat of hot water in the hot water tank, eliminating the risk of freezing.

(2) Since the knob of the operating section is inserted directly into the valve stem of the flow control valve, there is no need to drive it with a wire, etc., and the number of parts can be reduced, and the failure rate is also small.
