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

[0002]

2. Description of the Related Art FIG. 8 is an external view of a conventional sanitary washing device, and FIG. 9 is a schematic view showing a main part of its plane. 1 is a toilet bowl, 2 and 3 are washing nozzles which are hot water jetting means attached to the toilet bowl, 2 is an anus washing nozzle for washing the anus of the human body, and 3 is a bidet washing nozzle for washing the female part. . The anus washing nozzle 2 and the bidet washing nozzle 3 are shown in FIG.
As described above, the toilet bowl 1 is inserted from both sides toward the central portion of the toilet bowl, and when not in use, the nozzle cylinder 4 and the nozzle cylinder 4, respectively.
It is housed in the container 5, and only when in use, the hot water jet port projects onto the central axis of the toilet bowl 1 and jets hot water upward to serve each purpose. Reference numeral 6 is a main body of the cleaning device, in which a hot water tank, a pressure pump, a control device and the like are housed, and 7 is a power switch, 8
Is a hot water temperature adjusting knob, and 9 is a hot water amount adjusting knob. Reference numeral 10 denotes an operation knob in which a cleaning switch and a switching valve of the cleaning nozzle are interlocked with each other, and switches between off, anus cleaning, and bidet cleaning. Reference numerals 11 and 12 denote connection hoses for connecting the main body 6 of the cleaning device to the cleaning nozzle 2 for anus and the cleaning nozzle 3 for bidet, and supply hot water to each. 13 is a toilet seat on which the user sits, and 14 is a fecal pig.

In this structure, the user sits down on the toilet seat 13 and defecates, and then operates the operating knob 10 to wash the anus with the anus washing nozzle 2 or, in the case of a woman, the female local area. Clean with the bidet cleaning nozzle 3,
Particularly in the case of women, it is common to perform bidet washing after anus washing even after defecation, and during menstruation, anus washing after bidet washing. That is, after using one cleaning nozzle, the other cleaning nozzle is often used.

[0004]

In such a conventional sanitary washing device, when the bidet washing is performed after the anal washing, the bidet washing nozzle 3 is cooled, so that the hot water is cooled. This made it very stuffy, and this was an extremely inconvenient use because it was necessary to wash the anus with pleasant warmth (about 40 ° C.), then switch to bidet washing and suddenly pour cold water. In a toilet where the room temperature is 5 ° C or lower, such as in winter, the temperature of cold water becomes extremely low, and it even jumps. The wash area of women is particularly sensitive and the discomfort is significant. A very useful function for women, such as a bidet washing nozzle, would not be usable with such a thing. The same applies to the case of bidet washing to anal washing.

Further, conventionally, since the cleaning nozzles are located on both sides of the toilet bowl and the cleaning device body 6 containing the hot water tank is located on one side of the toilet bowl 1, the connecting hose for either one of the cleaning nozzles is very long. Become. In this conventional example, the hose 12 connected to the bidet cleaning nozzle 3 is long. And because the hose is long, the water is cooled during use,
The amount of residual water in the hose when not in use increases, which further promotes the harsh feeling in the early stages of use, and the warm water temperature during use also decreases as the room temperature becomes lower. There is a big difference in the thermal feeling between using the product and using it during the daytime, which is a problem. Further, since the connection hoses 11 and 12 have different lengths, there is a difference in the time from the operation of the operation knob 10 to the injection of hot water from the cleaning nozzles 2 and 3. That is, since the bidet cleaning nozzle 3 has the longer connection hose 12, the response speed becomes slower, which is a problem when the anus and the bidet are alternately used.

In order to solve these problems, the hot water tank may be located at the center of the nozzle so that the connecting hoses 11 and 12 have the same length and short length. In order to secure the degree of satisfaction in use, it is difficult to provide the hot water tank at the center of the nozzle due to its size, and it is unavoidable to place it in either one of the toilet bowls 1.
Therefore, when the cleaning nozzles are located on both sides of the toilet bowl 1, the above-mentioned drawbacks cannot be avoided.

Further, in the conventional example, since the cleaning nozzle is provided in the toilet 1, it is very dirty because it is contaminated with dirt and dirty water.

Further, since the direction of injection of hot water is vertical, there is an unpleasant sensation such as puncturing the washing part, and if the position is misaligned, the entire waist must be horizontally shifted and adjusted.

The present invention solves the above-mentioned drawbacks. In a sanitary washing device provided with a plurality of hot water jetting means, when one is used and the other is subsequently used, hot water is cooled by the cold hot water jetting means. It is possible to prevent the user from being chilled and spraying cold water to make the user feel uncomfortable, and even when switching the hot water spraying means, the user can comfortably wash without feeling the temperature change, and obtain the optimum hot water spraying angle. The purpose is to

[0010]

In order to achieve this object, the present invention is provided with a plurality of hot water jetting means for jetting hot water, which extends from the rear of a human body seated on a toilet seat, and the plurality of hot water jetting means are mutually connected. They are provided close to each other, and at least a part of them is integrally configured. One of the plurality of hot water jetting means is for anus washing and the other is for bidet, and the area of the bidet hot water jet is smaller than that of the anal washing hot water jet. Wider, the position of the bidet warm water jet when extended is anterior to the position where the anal flush hot water jet is extended, and the hot water jet angle from the bidet hot water jet with respect to the front horizontal direction. Is smaller than 90 °, and the hot water jet angle from the bidet hot water jet is larger than the hot water jet angle from the anus washing hot water jet with respect to the front horizontal direction.

[0011]

According to the sanitary washing device of the present invention, when one of the plurality of hot water jetting means is used, the other hot water jetting means is preheated by applying heat to the other hot water jetting means during hot water washing, thereby switching the hot water jetting means. Even if you go, hot water is not cooled.

Further, since the area of the bidet warm water jet (hereinafter referred to as bidet jet) is made larger than the area of the anus washing hot water jet (hereafter referred to as anal washing jet), the anal washing is jetted. The pressure is strong and the cleaning effect is high, and the bidet cleaning is soft and refreshing.

Further, since both the anal washing and the bidet washing are washing in a diagonal direction from the rear of the human body, there is no discomfort such as hot water sticking to the washing local area, and the body is slightly tilted even if the position is displaced. The position can be adjusted depending on the degree of movement.

Further, the position of the bidet injection port at the time of extension is in front of the position of the anal cleaning injection port, and the hot water injection angle from the bidet injection port with respect to the front horizontal direction is the anal cleaning injection. Since it is larger than the hot water spray angle from the mouth, it can be sprayed precisely on the washing local area.
There is no chance that the target will be missed and that you will not jump forward when cleaning the bidet.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an external view of a sanitary washing device showing an embodiment of the present invention, and FIG. 2 is a schematic plan view of FIG. 1 showing internal components necessary for explanation in broken lines.

FIG. 3 is a cleaning circuit diagram in which cleaning functional parts are arranged in the order of water channels. Reference numeral 15 is an apparatus main body having a cleaning function accommodated therein, 16 is a toilet seat on which a user sits, and 17 is a toilet lid. The toilet seat 16 and the toilet lid 17 are rotatably attached to the apparatus body 15 by a rotary shaft 18. The device body 15 is mounted on the toilet bowl 19. A pressurizing pump 20, a solenoid valve 21, and a hot water tank 22 placed in the right corner of the device body 15 are sequentially connected to the inside of the device body 15,
The hot water tank 22 is connected via a vacuum breaker 23 to a flow path switching valve 24 by a hose 25, and the flow path switching valve 24 is connected by hoses 26, 27 to two cleaning nozzles serving as hot water injection means. ing. The one connected to the hose 26 is the anus washing nozzle 28, and the one connected to the hose 27 is the bidet washing nozzle 29.
A water supply hose 31 provided with a filter 30 at the tip is connected to the apparatus main body 15, and the filter 30 is put into a toilet cleaning sister 32 that serves as a water source.

As shown in the exploded view of FIG. 4, the anal washing nozzle 28 and the bidet washing nozzle 29 are connected to each other by a guide portion 33.
The short side has a function for the anus and the long side has a function for the bidet, and they are provided in parallel with each other. 5 and 6 are cross-sectional views taken along a plane passing through the central axes of both. 34 is a nozzle 36 for cleaning the anus at the tip
No. 35 is a nozzle body having the same, and numeral 35 is also a nozzle body having an injection port 37 for bidet cleaning. Nozzle body 3
The outer shapes of both 4 and 35 are hexagonal except for the heads 34a and 35a, and have water passages 34b and 35b inside. 38 and 39 are cylindrical portions 40 and 4 of the guide portion 33.
Since the cylinders made of metal fitted in 1 are arranged in close proximity to each other, they can be thermally moved to each other. 42 and 43 are hexagonal rotation stoppers whose inner shape is slightly larger than the hexagonal dimensions of the nozzle bodies 34 and 35, and are fixed to the holes of the guide portion 33 with screws 44 and 45, respectively. The rotation of 35 is restricted. The screw holes 33a and 33b of the guide portion 33 are elongated holes,
There is a margin in the rotation direction for fixing the rotation stoppers 42 and 43, and the rotation direction can be adjusted. Numerals 46 and 47 are springs which urge the nozzle bodies 34 and 35 to be housed in the cylinders 38 and 39. Reference numerals 48 and 49 are water supply ports for introducing hot water into the cylinders 38 and 39. The flush nozzle is used when the hot water is supplied from the water supply ports 48, 49.
When the packings 50 and 51 provided on the heads of the nozzle bodies 34 and 35 come into contact with the cylindrical portions 40 and 41 of the guide portion 33, the gap between the nozzle bodies 34 and 35 and the guide portion 33 is sealed. At the same time, the projection of the nozzle bodies 34, 35 is stopped, and hot water is jetted from the jet ports 36, 37 toward the upper human body part.

FIG. 5 is a view showing that state, but for the sake of explanation, it shows a state in which both the anus and bidet washing nozzles are projected. In the case of this sanitary washing device, the flow path switching valve 24
The user selects and uses either one.

FIG. 6 shows a state in which hot water is not supplied to the cleaning nozzle. The cleaning nozzle for the anus and bidet is integrally housed in the apparatus body 15 as shown in FIG. 2, and with respect to the toilet bowl 19 and the central shaft 52 of the sanitary washing device,
The water supply ports 48 and 49 are attached obliquely to the hot water tank 22 side, and the central axis of the cleaning nozzle is directed obliquely downward. The anus washing nozzle 28 is closer to the central axis 52, and the anus washing nozzle 28 and the bidet washing nozzle are at the same height. When the nozzle bodies 34 and 35 are maximally projected, the ejection ports 36 and 37 are positioned on the central axis 52. The positions of the both in the front-back direction are the injection port 37.
Is about 3 cm ahead of 36, and the injection port 36,
The hole diameter of 37 is larger than that of the injection port 37 than that of the injection port 37. This is because the bidet cleaning nozzle is dimensionally longer and has a larger pressure loss.
Although the flow rates of the hot water injected from Nos. 6 and 37 are almost the same, the wash water from the injection port 37 is weaker in terms of injection pressure, and soft bidet cleaning is possible. For the anus, the injection pressure is strong and the cleaning effect is high, and for the bidet, soft and refreshing cleaning can be performed.

FIG. 7 is a schematic view showing a state where a person is washing with a sanitary washing device. The jet from the jet port 36 of the nozzle body 34 of the anus washing nozzle 28 (the jet angle α with respect to the front horizontal direction) is also used for the bidet washing nozzle 2.
The injection from the injection port 37 of the nozzle body 35 of No. 9 (the injection angle β with respect to the front horizontal direction) is also smaller than 90 °,
Moreover, β is larger than α. In this embodiment, α
Is about 50 ° and β is about 60 °. Therefore, unlike when washing from the vertical direction as in the conventional example, there is no discomfort that warm water enters the washing local area, and depending on how you sit on the toilet seat, you can tilt the body a little even if the washing position shifts a little. Easy alignment. Further, since the injection angle β for a bidet for washing the front of the human body is larger than α, there is no failure that the user sits too far behind the toilet seat and hot water jumps forward.

Reference numeral 53 in FIG. 1 is a knob interlocked with the flow path switching valve 24, and the user selects either the anus washing nozzle 28 or the bidet washing nozzle 29. 5
Reference numeral 4 denotes an operation knob which is interlocked with a drive device (not shown) for the pressurizing pump 20 and the solenoid valve 21. By operating this operation knob, cleaning can be performed.

Next, the operation of the structure of this embodiment will be described. The user sits on the toilet seat 16 and operates the operation knob 54.
When the is operated, the pressurizing pump 20 and the solenoid valve 21 are activated,
Water is sucked from the cistern 32 through the filter 30,
It is guided into the device body 15. Further, the water is pressurized by the pressurizing pump 20, enters the warm water tank 22, is warmed by a warm water heater (not shown), and becomes warm water of an appropriate temperature (about 40 ° C.) and is sent from the vacuum breaker 23 to the flow path switching valve 24. .
The user uses the knob 53 to switch the flow path switching valve 24 in accordance with the use of either anus washing or bidet,
In the case of anus washing, hot water is sent to the anus washing nozzle 28, and in the case of a bidet, hot water is sent to the bidet washing nozzle 29. The hot water sent to the cleaning nozzle enters the cylinder 38 or 39 through the water supply port 48 or 49 and applies a force to the nozzle body 34 or 35.

The nozzle body 34 or 35 has a spring 46.
Or, it moves inward of the toilet 19 against the load of 47,
The jet 36 or 37 of the nozzle body 34 or 35 is the toilet 1
When it comes out on the central axis 52 of 9, the packing 50 or 51 is
The nozzle body 34 or 35 stops projecting when it hits the cylindrical portion 40 or 41 of the guide portion 33. At that time, the hot water flows through the water passage 34b or 35b inside the nozzle body 34 or 35.
It is sprayed toward the local part of the human body through the injection port 36 or 37 and is used for cleaning. The jet ports 36 and 36 face the anus and the jet port 37 faces the female part. As described above, the washing can be performed at the most suitable position and jet angle. The washing pressure is also strong in the case of anal washing and weak in the case of bidet washing.

When the anal washing nozzle 28 is used first,
The anus cylinder 38 is warmed and the heat is transferred to the bidet cylinder 39 to preheat the entire bidet washing nozzle 29. Conversely, when the bidet washing nozzle 29 is used first, the anal washing is performed. Preheat the nozzle 28. This allows
Even if the flow path switching valve 24 is switched, hot water of an appropriate temperature is immediately jetted from the cleaning nozzle on the switched side. Therefore, even if one of the cleaning nozzles is used and then switched to the other, there is almost no possibility that hot water is cooled by the switched cleaning nozzle to discharge cold water, and cleaning can be continuously performed with comfortable warm water. In particular, women often switch and use the product after washing once, and at that time, there is almost no feeling of a scary feeling when switching.

An anus washing nozzle 28 and a bidet washing nozzle 29 are mounted in parallel, and water supply ports 48, 4 are provided.
Since 9 is close to each other, the connecting hoses 27 and 28 from the flow path switching valve 24 to the cleaning nozzles 28 and 29 of both are almost the same size. Therefore, the response speeds of the respective washing nozzles become substantially equal, and even if the anus and the bidet are used alternately, it is possible to wash without feeling unnatural.

Further, when washed, dirt is scattered,
Due to the shape of the cleaning part, the cleaning part scatters in the direction of the central axis of the toilet bowl 19. In this embodiment, since the cleaning nozzles 28 and 29 are both mounted obliquely with respect to the central axes of the apparatus main body 15 and the toilet bowl 19, scattering of dirt is less likely to occur.
It is less likely that the cleaning nozzle will be clogged with dirt and that sliding failure will cause corrosion and other problems.

Further, since both the water supply ports 48 and 49 face the hot water tank 22 and the flow path switching valve 24 side, the connecting hoses 27 and 26 become short, and the residual water in the piping is minimized. Since the washing nozzles 28, 29, the hoses for connection, 26, 27 and the hot water tank 22 are housed in the main body 15 of the apparatus, they are kept warm, and the temperature drop when not in use is small. Since the washing nozzle 28 is attached to the side closer to the toilet central axis 52 than the bidet washing nozzle 29, the jet ports 36, 37 of the nozzle bodies 34, 35 are attached.
In order to come out on the central axis of the toilet bowl,
Is shorter than the bidet cleaning nozzle 29. Therefore, the bidet washing nozzle 29 has a larger pressure loss, and the bidet-side washing pressure is softer than the anus-side washing pressure. Reasonable cleaning is possible, the feeling of cleaning is good, and the cleaning effect is high.

In this embodiment, the case where the anus washing nozzle body 34 and the bidet washing nozzle body 35 are independent has been described, but two water channels for anus and bidet are provided in one nozzle body. Even in this case, the same effect can be obtained.

[0030]

As described above, according to the present invention, there are provided a plurality of hot water ejecting means for ejecting hot water, which extend from the rear of the human body sitting on the toilet seat, and the plurality of hot water ejecting means are provided close to each other and at least one of them is provided. Since the part is integrally configured, when one of the plurality of hot water jetting means is used, heat can be applied to the other hot water jetting means during the hot water washing to preheat the hot water jetting means. , The hot water is never cooled. Therefore, it is possible to comfortably wash immediately after switching.

Further, since the area of the bidet jet is made larger than that of the anus washing jet, the anal washing has a high jetting pressure and a high washing effect, and the bidet washing is soft and refreshing.

Since both the anal washing and the bidet washing are washing in a diagonal direction from the rear of the human body, there is no discomfort such as hot water sticking to the washing local area, and the body is slightly tilted even if the position is displaced. You can easily adjust the position by just doing.

In addition, the position of the bidet injection port at the time of extension is in front of the position of the anal cleaning injection port, and the hot water injection angle from the bidet injection port with respect to the front horizontal direction is the anal cleaning injection. Since it is larger than the hot water spray angle from the mouth, it can be sprayed precisely on the washing local area.
There is no chance that the target will be missed and that you will not jump forward when cleaning the bidet.
