Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water washing device for washing a human body part.

[0002]

2. Description of the Related Art Conventionally, in a hot water washing apparatus, the wash water supplied from a pressure water source can be warmed to a desired temperature in a hot water tank provided in the apparatus. The human body is cleaned by being ejected from the cleaning nozzle extending from the storage position behind the toilet bowl to the cleaning position. After the cleaning is completed, the cleaning nozzle is retracted to the storage position to wait for the next cleaning. The injection of cleaning water is turned on and off by opening and closing a solenoid valve arranged on the upstream side of the cleaning nozzle, but after the cleaning, the cleaning nozzle and the passage connecting the cleaning nozzle and the hot water tank are The cleaning water remains as cooling water. This cooling water was spouted from the cleaning nozzle at the time of the next cleaning, which was uncomfortable for the user.

As a solution to this problem, Japanese Patent Publication No. 6
What is disclosed in Japanese Patent Laid-Open No. 3-35771 is known. In the human body local cleaning device disclosed in this publication, cleaning water is supplied to the cleaning nozzle by a pump.
The amount of cleaning water supplied from this pump to the cleaning nozzle is kept small for a certain period of time after the cleaning instruction is given by the cleaning switch, and the amount of cleaning water is discharged from the tip of the nozzle so that it does not come into contact with the human body. The amount is changed so that the human body can be washed. In this way, immediately after the cleaning instruction, the cooling water accumulated in the nozzle and the passage is discharged, and then,
By cleaning the human body, cooling water is prevented from splashing on the human body.

[0004]

However, in the above-mentioned conventional example, the rotational speed of the pump is controlled by controlling the variable resistor inserted in the power supply circuit of the pump, and the discharge amount of hot water from the nozzle is sequence-controlled. It is supposed to do. Therefore, there is a problem that the structure for limiting the discharge amount such as the pump and the variable resistor is complicated.

Therefore, it is a technical object of the present invention to provide a warm water washing toilet seat having a simpler structure and capable of ejecting washing water from the nozzle to the extent that it is not ejected to the human body.

In a hot water washing device comprising a solenoid valve, a water amount adjusting means and a hot water tank arranged in series in the water passage, and a control means for controlling opening / closing of the solenoid valve and the water amount adjusting means, the water amount adjusting means is A water amount adjusting means and an orifice means arranged in parallel with the jetted water amount adjusting means are provided,
When the electromagnetic valve is in the open state and the jet water amount adjusting means is in the closed state, a small amount of wash water that does not come into contact with the human body is supplied to the nozzle means, which is preferably a hot water washing apparatus. The nozzle means includes an anus washing nozzle device, a bidet washing nozzle device arranged in parallel with the anus washing nozzle device, an anus washing nozzle device and an upstream side of the bidet washing nozzle device. And a switching valve means arranged to supply cleaning water to at least one of the anus cleaning nozzle device and the bidet cleaning nozzle device when the electromagnetic valve is opened. ..

[0008]

When a small amount of washing water that does not come into contact with the human body is supplied to the nozzle means, the electromagnetic valve is opened and the jet water quantity adjusting means is closed. The washing water thus supplied from the pressure water source is supplied to the nozzle means through the orifice means after passing through the electromagnetic valve. Since the flow path of the wash water is throttled by the orifice means, only a small amount of wash water is supplied to the nozzle means, and therefore the cooling water in the passage connecting the nozzle means and the pressure water source is discharged from the nozzle means. It is not ejected from the nozzle means to the human body. In this way, by opening only the solenoid valve, the cooling water in the passage is discharged.

When the human body is washed, the solenoid valve and the jet water amount adjusting means are opened, and the washing water passing through the solenoid valve is supplied to the nozzle means not only through the orifice means but also through the jet water amount adjusting means. To be done. In this way, the amount of washing water can be increased by the amount by which the jet water amount adjusting means is opened, and the washing water having the water pressure that comes into contact with the human body is jetted.

Water is also sent to the water passage 16d through 6a or 27a. The sum of the diameters of the orifice 22 and the orifice 23 opened to the maximum is smaller than the diameter of the orifice 25a, and the amount of washing water passing through the orifices 22 and 23 is ejected from the nozzle to the human body part. It is set so that the amount of water is not so large. Further, of the orifices 25a, 26a and 27a, the diameter of the orifice 27a is the largest, followed by the orifice 26a and the orifice 25a.

The washing water sent to the water passage 16d through the water quantity control valve device 20 is sent to the hot water tank 28. The wash water heated to a desired temperature by the heater 28a (FIG. 2) is supplied to the hot water tank 28 through the water passage 16e and the switching valve 29 including the first electromagnetic valve 29a and the second electromagnetic valve 29b.
Sent to. The first electromagnetic valve 29a opens and closes water to the anus washing nozzle device 30, and the second electromagnetic valve 29b opens and closes water to the bidet washing nozzle device 40.

Next, the structure of the anus washing nozzle device 30 will be described with reference to FIG. Since the basic structure of the bidet washing nozzle device 40 is substantially the same as that of the anus washing nozzle device 30, detailed description thereof will be omitted here. The anus washing nozzle device 30 includes a cylinder 31 whose rear end is fixed to the main body 2. Inside the cylinder 31, the cylinder chamber 3
5 is formed, and an anus washing nozzle (hereinafter, referred to as a nozzle) 32 is housed in the cylinder chamber 35. An inclined portion 32 a is formed behind the nozzle 32, and when the nozzle 32 extends from the cylinder 31, the inclined portion 32 a is formed on the cylinder 31.
The extension position is regulated by making contact with a.
The contact between the inclined portions 31a and 32a seals the space between the cylinder 31 and the nozzle 32. A spring 34 is wound around the outer periphery of the nozzle 32, one end of which is inclined by the inclined portion 32 a of the nozzle 32 and the other end of which is locked by the tip of the cylinder 31. The nozzle 32 is always urged by the urging force of the spring 34 in the direction of being housed in the cylinder 31. Nozzle 32
A water passage 36 is formed inside, one end of the water passage 36 communicates with a jet outlet 37 formed on the upper surface of the tip of the nozzle 32, and the other end of the water passage 36 opens on the rear surface of the nozzle 32. It communicates with 38. When the nozzle 32 extends and the inclined portion 32a of the nozzle 32 and the inclined portion 31a of the cylinder 31 are in contact with each other, the water supply port 38 is provided with a recess 31b formed in the inner periphery of the cylinder 31 so that the cylinder chamber Although it is in complete communication with the cylinder 31, even when housed in the cylinder 31, the gap between the cylinder 31 and the piston 33 formed at the rear end of the nozzle 32 causes the cylinder 31
It slightly communicates with the water pipe 39 connected to the rear end of the.

Next, the operation when the cooling water is discharged will be described. In this embodiment, when the user sits on the toilet seat 4,
The cooling water in the warm water cleaning device 1 is discharged by the action described below.

First, when the user sits on the toilet seat 4, the human body detection sensor 15 detects the user and sends a signal to the control device C. In response to this, the control device C opens the water supply solenoid valve 17, the first solenoid valve 29a, and the second solenoid valve 29b. When the water supply solenoid valve 17 is opened, the cleaning water is supplied to the water circuit in the hot water cleaning device 1, and the cleaning water that has passed through the water supply solenoid valve 17 is regulated by the pressure regulating valve 1.
At 8 the pressure is adjusted to the set pressure and the water is sent to the water quantity control valve device 20. The water amount adjusting means 20 is provided with five passages of an orifice 22, an orifice 23, a first water amount adjusting valve 25, a second water amount adjusting valve 26 and a third water amount adjusting valve 27 in parallel, but discharges cooling water. In some cases, the first to third water amount adjusting valves 25 to 27 are closed.

Therefore, the cleaning water is supplied to the hot water tank 28 through the orifices 22 and 23. In this way, the hot water in the hot water tank 28 is pushed out to the water passage 16e, passes through the first electromagnetic valve 29a and the second electromagnetic valve 29b opened by the control device C, and the anus washing nozzle device 30 and the bidet washing nozzle. Water is passed to the device 40. For example, the warm water sent to the anus washing nozzle device 30 is
Water is supplied to the cylinder chamber 35 through the water passage 39 from the gap between the cylinder 31 and the piston 33, and the cooling water in the cylinder chamber 35 is drained from the tip of the cylinder 31. The hot water supplied to the cylinder chamber 35 enters the water passage 36 from the water supply port 38 of the nozzle 32, and the cooling water in the nozzle 32 is discharged from the jet port 37 at the tip of the nozzle. At this time, the amount of warm water supplied to the cylinder chamber 35 is such that the nozzle 32 is not extended, and the cooling water is drained while the nozzle 32 is still stored in the cylinder 31. The cooling water is also discharged from the bidet cleaning nozzle device 40. When the predetermined time elapses in this way, the controller C closes the water supply solenoid valve 17, the first solenoid valve 29a, and the second solenoid valve 29b to stop the supply of cleaning water, and the cooling water is also discharged. Thus, at the same time when the user sits down on the toilet seat 4, the anus washing nozzle device 30,
The cooling water accumulated in the bidet cleaning nozzle device 40 is discharged, and the cooling water is not discharged regardless of whether the user cleans the anus or the bidet at any time.

Next, the operation when performing anal irrigation will be described. When the user turns on the anus cleaning switch 5a arranged on the upper surface of the main body 2, the control device C opens the water supply electromagnetic valve 17 to supply the cleaning water to the water circuit in the warm water cleaning device 1. At the same time, the control device C adjusts the first amount of water so that the amount of water designated by the water amount adjusting switch 6a of the second operating section 6 becomes the first
At least one of the water amount adjusting valve 25, the second water amount adjusting valve 26, and the third water amount adjusting valve 27 is opened. For example, when the user selects the weakest cleaning strength, only the first water amount control valve 25 is opened and the cleaning water flows through the orifice 25.
Allow passage through a. Thus, the wash water is supplied to the warm water tank 51 through the orifices 22, 23 and 25a. Then, water is supplied to the anus washing nozzle device 30 through the first electromagnetic valve 29a opened by the control device C. In the case of anus washing, unlike the case of discharging cooling water, a large amount of water is supplied as much as the first water amount adjusting valve 25 is opened, and the water pressure of hot water supplied to the cylinder chamber 35 from the water pipe 39 is used. The piston 33 is pressed and the nozzle 3
2 is extended. In this way, when the inclined portion 32a of the nozzle 32 comes into contact with the inclined portion 31a of the cylinder 31, the extension of the nozzle 32 is stopped, and the cleaning water supplied to the water passage 36 of the nozzle 32 is ejected from the ejection port 37 toward the human body. It At this time, since the gap between the cylinder 31 and the nozzle 32 is sealed by the inclined portions 31a and 32a, the cleaning water does not leak from the tip of the cylinder 31. Next, when the end of the anal washing is input by the stop switch 5d or 6d, the control device C causes the water supply solenoid valve 17, the first
The water amount control valve 25 and the first electromagnetic valve 29a are closed to stop the supply of the washing water to the anus washing nozzle device 30. Therefore,
The nozzle 32 is housed in the cylinder 31 by the urging force of the spring 34, and the anus washing is completed.

The washing strength of the anus washing can be adjusted by combining the opening and closing of the first to third water amount adjusting valves 25 to 27 as shown in Table 1. The opening / closing of each solenoid valve during bidet cleaning is as shown in Table 2.

In this embodiment, the human body detection sensor 15 detects the human body and drains the cooling water at the same time.
At the same time when the anus washing switch 5a or the bidet washing switch 5b is turned on, the cooling water may be discharged for a predetermined time, and then the anus washing or the bidet washing may be performed. In this case, it is not necessary to open both the first electromagnetic valve 29a and the second electromagnetic valve 29b, and only the electromagnetic valve that communicates with the nozzle device in which cleaning is performed may be opened.

Further, in this embodiment, the water quantity control valve device 20 is used.
Further, an orifice 23 is arranged side by side with the orifice 22 and the diameter of the orifice 23 can be changed manually, so that the drainage amount and the cleaning flow rate of the cooling water can be adjusted.
