Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a sanitary cleaning device for cleaning private parts of the human body with warm water or the like.

Structure of a conventional example and its problems FIG. 1 shows an external view of a conventional sanitary cleaning device, and FIG. 2 is a schematic plan view showing the main parts thereof.

1 is a toilet bowl; 2 and 3 are cleaning nozzles attached to the toilet bowl 1; 2 is an anal cleaning nozzle for cleaning the anal region of the human body; 3;
is a bidet cleaning nozzle for cleaning women's private parts. The anal cleaning nozzle 2 and the bidet cleaning nozzle 3 are as shown in Fig. 2.
It is inserted from both sides of the toilet bowl 1 toward the center of the toilet bowl, and when not in use, it is stored in the Nomerin Lindas 4 and 5, respectively, and only when in use, the hot water injection port protrudes on the central axis of the toilet bowl 1, and the hot water jet is inserted upward. Hot water is injected into the tank and used for each purpose.

6 is the main body of the cleaning device, which contains 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 adjustment knob, and 9 is a hot water temperature adjustment knob. Reference numeral 10 is an operation knob that is linked to the cleaning switch and the switching valve of the cleaning nozzle, and is used to turn off and clean the anus.

This is to switch bidet cleaning. 11.12 is the cleaning device main body 6, the anal cleaning nozzle 2, and the bidet cleaning nozzle 3
It is a connection hose that connects the two, and supplies hot water to each. 13 is a toilet seat on which the user sits, and 14 is a toilet pig.

In this configuration, after sitting on the toilet seat 13 and defecating, the user operates the operating knob 10 to clean the anal area with the anal cleaning nozzle 2, or in the case of a woman during her menstrual period, the user cleans her private parts. is washed with bidet cleaning nozzle 3,
Especially in the case of women, it is common to wash the anus and then wash the bidet even after defecating, and during menstruation, it is common to wash the anus after washing the bidet. 5.9 After using one cleaning nozzle, the other cleaning nozzle is often used.

However, with conventional sanitary cleaning devices, when you perform bidet cleaning after anal cleaning, the bidet cleaning nozzle 3 is cold, so the hot water is cooled and you feel like filling it up, which is pleasant. After cleaning the anus at a warm temperature of about 40°C, the user had to switch to bidet cleaning and suddenly splash cold water, which was very inconvenient in use. In toilets where the room temperature drops below 5 IP°C, such as during the winter, the temperature of the cold water can get so low that it can make you jump.

Women's washing areas are particularly sensitive and the discomfort is significant. A bidet cleaning nozzle, which is a very useful feature for women, would be unusable if it were like this. The same thing can be said when performing anal cleaning from bidet cleaning.

In the past, the cleaning nozzles were located on both sides of the toilet bowl, and the cleaning device main body 6 containing the hot water tank was located on one side of the toilet bowl 1, so the connection hose for either one of the cleaning nozzles was extremely long. In this conventional example, the hose 12 connected to the bidet cleaning nozzle 3 is long. Also, because the hose is long, the water is cooled even during use, and there is a lot of water left in the hose when it is not in use, which further exacerbates the cold feeling at the beginning of use. The lower the room temperature is, the lower the temperature of the hot water becomes, and this is a problem because the temperature feels very different depending on the season and whether you use it in the morning or evening or during the day. It's ox, connection hose 11.1
Since the lengths of 2 are different, after operating the operation knob 10,
There is a difference in the time it takes for hot water to be sprayed from the cleaning nozzles 2 and 3. That is, since the connection hose 12 of the bidet cleaning nozzle 3 is longer, the response speed is slower, which is a problem when the bidet cleaning nozzle 3 is used alternately for the anus and the bidet.

In order to solve these problems, the hot water tank should be located in the center of the nozzle and the lengths of the connecting hoses 11 and 12 should be made equal and short, but the width of the toilet seat 1 should also be made standard, and the amount of hot water should be adjusted accordingly. 2 In order to ensure a satisfactory level, it would be difficult to install the hot water tank in the center of the nozzle due to dimensions, and it would be necessary to place it on either side of the toilet bowl 1. Therefore, it is necessary to install the flushing nozzle on both sides of the toilet bowl 1. In this case, the above-mentioned drawbacks cannot be avoided.

Furthermore, in the conventional example, since the cleaning nozzle is provided inside the toilet bowl 1, the toilet bowl 1 is exposed to filth and sewage, making it extremely unclean.

Purpose of the Invention The present invention solves the above-mentioned drawbacks of the conventional example. In a sanitary washing device equipped with a plurality of washing nozzles, when one is used and then the other is used, hot water is not supplied to the cold nozzle. To prevent a user from feeling uncomfortable by spraying cold water, and to enable the user to wash comfortably without feeling any temperature change even when switching nozzles.

Structure of the Invention In order to achieve the above object, in the sanitary cleaning device of the present invention, a plurality of cleaning nozzles are placed close to each other, and while one is in use,
Heat is applied from the cleaning nozzle in use to the other cleaning nozzle to keep it warm, so that the hot water will not be cooled even if the nozzle is switched.

A pressurizing pump 20, a solenoid valve 21, and a hot water tank 22 placed on the right side of the device main body 15 are sequentially connected inside the device main body 15. It is connected to the passage switching valve 24 with a hose 25, and from the passage switching valve 24, two
It is connected to two cleaning nozzles with hoses 26 and 27.

The one connected to the hose 26 is an anal cleaning nozzle 28, and the one connected to the hose 27 is a bidet cleaning nozzle 29. A water supply hose 31 having a filter 30 at its tip is connected to the device main body 16, and the filter 30 is introduced into a toilet cleaning cistern that serves as a water source.

The anal cleaning nozzle 28 and the bidet cleaning nozzle 29 are the sixth
As shown in the exploded view of the figure, the guide portion 33 is a two-piece unit, with the shorter side serving as an anus and the longer side serving as a bidet, and both are provided in parallel. 7 and 8 are cross-sectional views taken along a plane passing through their central axes. Reference numeral 34 denotes a nozzle main body having an injection port 3e for cleaning the anus at its tip, and numeral 36 denotes a nozzle main body having an injection port 37 for cleaning the bidet. Nozzle body 34.3
5 has a hexagonal outer shape except for the heads 34a and 36a, and has water passages 3ab and 35b inside. 38.39 is the cylindrical part 40.41 of the guide part 33
The metal cylinders are fitted into the metal cylinders and are placed close to each other in parallel, allowing thermal movement between them. Reference numerals 42 and 43 refer to rotation stoppers whose inner shape is slightly larger than the hexagonal dimensions of the nozzle bodies 34 and 325, and are fixed to the holes of the guide portion 33 with screws 44 and 45, respectively, so that the nozzle The rotation of the main body 34 and 35 is regulated in four ways.

The screw holes 33a and 33b of the guide part 33 are elongated holes, and there is a margin in the rotational direction for fixing the rotation stoppers 42, 43, and the injection angle can be adjusted.

Reference numerals 46 and 47 denote springs that bias the nozzle bodies 34 and 35 in the direction of housing them into the cylinders 38 and 39. 4
8.49 is a water supply port that introduces hot water into the cylinders 3B' and 39. When the cleaning nozzle is supplied with warm water from the water supply port 48° 49, it moves to the toilet bowl 19 side, and the nozzle body 34.3
(7) When the cylindrical parts 40 and 41 come into contact with the cylindrical parts 40 and 41,
At the same time as the gap between the nozzle body 34, 35 and the guide part 33 is sealed, the nozzle body 34, 35 stops protruding, and hot water is sprayed upward from the injection ports 38, 37 toward the private parts of the human body.

FIG. 7 is a diagram showing the state, but for the purpose of explanation, for anus,
Both bidet cleaning nozzles are shown in a protruding state. In the case of this sanitary cleaning device, the user selects and uses either one using the flow path switching valve 24. FIG. 8 shows a state in which hot water is not supplied to the cleaning nozzle.

This cleaning nozzle for anus and bidet is the fourth one.
As shown in the figure, it is stored in the device main body 16, and the toilet bowl 19
and the water supply port 48 . with respect to the central axis 52 of the sanitary cleaning device.
49 is attached diagonally to the hot water tank 22 side, and the central axis of the cleaning nozzle is directed diagonally downward.

The anal cleaning nozzle 28 is closer to the central axis 62,
The anal cleaning nozzle 28 and the bidet cleaning nozzle are at the same height. The nozzle body 34.35 is sized such that the injection port 36.37 is located on the central axis 62 when the nozzle body 34.35 is fully protruded. Regarding the longitudinal position of both, the injection port 37 is located about 3 cm ahead of the injection port 36, and the hole diameter of the injection port 36 and 37, which is facing the optimal direction of the cleaning position, is 3 cm.
6. This is because the bidet cleaning nozzle is longer in size and has a larger pressure drop.
As a result, the hot water flow rates injected from the injection ports 36 and 37 are approximately the same, but the injection pressure is
The wash water from the machine is weaker, allowing for softer bidet washing. The one for the anus has a strong spray pressure and has a high cleaning effect, while the one for the bidet has a soft and gentle cleaning.

Reference numeral 53 in FIG. 3 indicates a sweetness linked to the flow path switching valve 24, and the user selects either the anus cleaning nozzle 28 or the bidet cleaning nozzle 29. Reference numeral 64 indicates an operation unit linked to a driving device (not shown) for the pressurizing pump 20 and the electromagnetic valve 21, and cleaning can be performed by operating this unit.

In this configuration, when a user sits on the toilet seat 16 and operates the operating knob 64, the pressurizing pump 2o and the electromagnetic valve 21 are activated, and water is sucked from the cistern 32 through the filter 30 and guided into the device main body 15. Furthermore, the water is pressurized by the pressure pump 2o, enters the hot water tank 22, is heated by a hot water heater (not shown), becomes hot water at an appropriate temperature (approximately 40°C), and is sent from the vacuum breaker 23 to the flow path switching valve 24. It will be done. The user uses the knob 53 to switch the flow path switching valve 24 depending on whether the user wants to use the anus cleaning or bidet. Hot water is sent to the bidet cleaning nozzle 29. The hot water sent to the cleaning nozzle is supplied to the water supply port 48.
or 49 into the cylinder 38 or 39 and applies a force to the nozzle body 34 or 35.

The nozzle body 34 or 36 moves inward of the toilet bowl 19 against the load of the spring 46 or 47, and the nozzle body 3
The injection port 36 or 37 of 4 or 35 is located on the central axis 5 of the toilet bowl 19.
2, when the packing 5o or 61 comes out on the guide part 33
corresponds to the cylindrical portion 40 or 41 of the nozzle body 34 or 3
5 stops protruding. At that time, the hot water flows through the nozzle body 34
Alternatively, it is sprayed from the injection port 36 or 37 through the water passage 34b or ssb inside the body 36 toward the private parts of the human body for cleaning. FIG. 9 schematically shows a state in which a person is washing using the sanitary washing device. The nozzle 36 faces the anus, and the nozzle 37 faces the female private parts, and the position in the direction of the central axis 52 is also located at the most suitable position for cleaning.

The cleaning pressure is also stronger for anal cleaning and weaker for bidet cleaning.

When the anal cleaning nozzle 28 is used first, the anal cylinder 38 is heated, and the heat is transferred to the bidet cylinder 39.
When the bidet cleaning nozzle 29 is used first, the entire bidet cleaning nozzle 29 is preheated. Conversely, if the bidet cleaning nozzle 29 is used first, the anal cleaning nozzle 28 is preheated. As a result, even if the flow path switching valve 24 is switched, hot water at an appropriate temperature is immediately injected from the cleaning nozzle 2 on the switched side.

In this way, according to this embodiment, even if you use one cleaning nozzle and then switch to the other,
The hot water is cooled by the switched washing nozzle, and there is almost no need to discharge cold water, allowing continuous washing with comfortable warm water. In particular, women often switch to use it when washing their clothes, and when they do so, there is almost no tingling sensation when switching.

In addition, an anal cleaning nozzle 28 and a bidet cleaning nozzle 29
are installed in parallel, and the water supply ports 48 and 49 are close to each other, so that both cleaning nozzles 28.
Hose 2 of connection to 29 completed.

28 have almost the same dimensions. Therefore, the response speed of each cleaning nozzle is approximately equal, and even if the anal and bidet cleaning nozzles are used alternately, cleaning can be performed without feeling unnatural.

Moreover, when cleaning, the filth scatters in the direction of the central axis of the toilet bowl 19, considering the shape of the cleaning part. In this embodiment, since the cleaning nozzles 28 and 29 are both installed obliquely with respect to the central axes of the main body 15 and the toilet bowl 19, they are less likely to be exposed to the scattering of filth, and therefore, the cleaning nozzles are prevented from being clogged by filth. Failures such as poor sliding and corrosion are rare.

In addition, since both the water supply ports 48 and 49 face the hot water tank 22 and the flow path switching valve 24 side, the connection hose 27.
26 is shorter, the residual water in the piping can be minimized, and the cleaning nozzle 28゜29 and the connecting hose 2 can be shortened.
6.27 and the hot water tank 22 are housed within the main body 15 of the device, so they are kept warm and the temperature decreases little when not in use.

In addition, since the anal cleaning nozzle 28 is attached closer to the toilet central axis 62 than the bidet cleaning nozzle 29,
In order for the injection ports 36 and 37 of the nozzle bodies 34 and 35 to emerge on the central axis of the toilet bowl, the anal cleaning nozzle 28 is shorter than the bidet cleaning nozzle 29. Therefore, the bidet cleaning nozzle 29 has a larger pressure loss, and the cleaning pressure on the bidet side is softer than the cleaning pressure on the anus side. Reasonable cleaning is possible, the cleaning feeling is good, and the cleaning effect is also high.

This effect can be obtained.

Effect of the invention According to the present invention, the following effects can be obtained.

(1) Even if you use one cleaning nozzle and then switch to the other, the cleaning nozzle on the side you switched to from the previous cleaning will have been preheated, so in most cases you will be sprayed with cold water at the initial stage of switching. It is possible to wash continuously at an appropriate temperature.

(The cleaning nozzle is installed diagonally with respect to the central axis of the toilet bowl, so the spray nozzle 40 for both the anus and the bidet can protrude above the central axis of the toilet bowl, making it possible to reach the cleaning position.) Not only that, but the washing nozzle is less likely to be exposed to scattering of dirt, and it is possible to prevent the cleaning nozzle from malfunctioning or becoming contaminated.

(Saki) Since both cleaning nozzles are close to each other, the lengths of the hoses connected to both cleaning nozzles can be made equal, and the response speeds of both cleaning nozzles are almost equal.
Even when used alternately, there is no unnatural effect.

(In the fourth embodiment, the cleaning nozzle is installed inside the main body of the device, so the heat retention of the hot water is good, and there is little possibility that the cleaning nozzle itself will be contaminated.

(In the embodiment, the anal cleaning nozzle is located closer to the central axis of the toilet bowl than the bidet cleaning nozzle, so the anal cleaning nozzle is shorter than the bidet cleaning nozzle and has less pressure loss.

Therefore, the anal cleaning effect is also high.
