Abstract

A hygiene cleaning device that prevents cleaning water from splashing on a human body and sufficiently prevents human wastes from adhering to a toilet bowl. The hygiene cleaning device (100) has a toilet bowl nozzle (40). The toilet bowl nozzle (40) has a toilet bowl nozzle body (41) and a jet flow forming member (42) inserted in the toilet bowl nozzle body (41). A gap is provided between the toilet bowl nozzle body (41) and the jet flow forming member (42) so that the jet flow forming member (42) is freely movable in the toilet bowl nozzle body (41). If the gap functioning as a flow path for the cleaning water were non-uniformly formed,the distribution of pressure in the flow path would be non-uniform to cause a jet flow ejected from the toilet bowl nozzle (40) to be a deviated flow. However, because the jet flow forming member (42) is freely movably installed, the pressure of the cleaning water acts in the direction in which the gap becomes uniform. As a result, the position of the jet flow forming member (42) is automatically corrected to make the jet flow from the toilet bowl nozzle (44) uniform.

Description

Sanitary cleaning device

technical field

The invention relates to a sanitary cleaning device with a toilet nozzle for cleaning a toilet.

Background technique

Conventionally, in order to prevent dirt from adhering to the toilet, various sanitary cleaning devices have been developed (for example, refer to Patent Document 1).

In the sanitary cleansing device described in Patent Document 1, when a person sits on the toilet seat, cleansing water is sprayed from the toilet nozzle toward the inner surface of the toilet. Therefore, the inner surface of the toilet is wetted with the washing water to form a water film on the surface of the toilet, thereby preventing dirt from adhering to the toilet.

Patent Document 1: Japanese Patent Application Laid-Open No. 7-189319

In the sanitary cleaning device described in Patent Document 1, the toilet nozzle is provided with a cover body at the front end of the toilet nozzle body, and a predetermined gap is formed between the nozzle body and the cover body, thereby constituting the gap as a discharge port. Jet flow is sprayed to the inner surface of the toilet all around.

The amount of water that can be used for cleaning the toilet is about the same as the amount of water used by the sanitary cleaning device at about 1L/min. If there are deviation factors such as the sameness of the flow, it is necessary to spray the jet flow to the whole circumference, and the jet flow velocity should be at least 4m/sec or more. In order to achieve 4 m/sec as the ejection speed of the jet flow, if the diameter of the tip of the toilet nozzle is 4 mm, the width of the gap at the tip of the toilet nozzle needs to be 0.3 mm or less. In order to spread the spray flow from the gap at the front end of the toilet nozzle equally around the entire periphery, there is the following problem: If the gap of the flow path is not limited to a width of at least ±0.05 mm with respect to the gap of 0.3 mm Inside, the jet spreads unevenly. It is very difficult to suppress the variation of the gap in the axial direction within ±0.05 mm.

In addition, there is a problem that the spray angle of the jet stream sprayed from the toilet nozzle is not uniform or unstable. Although the spray angle of the jet stream sprayed from the toilet nozzle is determined by the spray angle formed by the spray port, the jet stream is sprayed from a very narrow spray port, and the jet stream is directed toward the spray direction of the jet stream Due to the short length of the nozzle, there is a problem that the ejection direction of the jet flow is easily changed due to the fine burr of the ejection port or the minute curved surface at the ejection port, and a predetermined ejection angle cannot be obtained.

In addition, in order to form a uniform water film on the surface of the toilet as much as possible, it is preferable to set the arrival position of the jet stream sprayed from the toilet nozzle relative to the vertical direction of the toilet within the range that does not fly out of the toilet and to be as close as possible to the surface of the toilet. above. Therefore, although the arrival position of the jet flow is set near the upper surface of the toilet, when the jet flow itself splashes and sprays out, droplets of the jet flow may fly over the top of the toilet bowl or wet the floor of the toilet. Then there is the problem as follows: the jet stream that spreads thinly in the same way as to reach the toilet surface, the flow velocity is accelerated to more than 4m, and the jet stream itself becomes a thin film, so there is a jet stream that is easy to become splashed, especially when the jet stream is sprayed out. When the flow of the jet flow at the outlet is disturbed, the jet flow becomes very likely to splash when it reaches the surface of the toilet, and the splashed water bubbles disperse and reach the toilet seat or the outside of the toilet.

In addition, since the discharge port is very narrow, there is a problem that dirt and scale adhere to the discharge port, the discharge direction of the jet flow changes, or clogging occurs in extreme cases. In addition, there are also problems when cleaning the discharge port. In some cases, there is still room for improvement from the viewpoint of ensuring sufficient cleanability because the discharge port is very narrow and difficult to clean.

The present invention has been made in view of the problems of the prior art described above, and an object of the present invention is to provide a sanitation cleaning device having a structure that improves the accuracy of the spray direction and the spray range of the jet stream sprayed from the toilet nozzle and enables The stability of the jet flow is improved, and the jet flow ejected from the toilet nozzle uniformly reaches the surface of the toilet bowl in a wide range to form a water film, and also has sufficient cleaning properties.

<3> Structure of the water supply system and control system of the main body

FIG. 3 is a schematic diagram showing the structure of the main body portion 200 . As shown in Figure 3, the main body 200 includes a branch valve plug 2, a filter 4, a one-way valve 5, a constant flow valve 6, a water stop solenoid valve 7, a flow sensor 8, a heat exchanger 9, a pump 11, and a buffer tank 12 , the switching valve 13 for the human body, the nozzle unit 20 , the vacuum breakers 31 and 61 , the toilet nozzle 40 , the toilet nozzle motor 40 m , the lamp 50 and the control unit 90 .

The nozzle unit 20 includes a rear nozzle 21, a bidet nozzle 22, and a nozzle cleaning nozzle 23, and the switching valve 13 for a human body includes a switching valve motor 13m.

As shown in FIG. 3 , a branch valve plug 2 is inserted into the water pipe 1 . A filter 4 , a check valve 5 , a constant flow valve 6 , a water stop solenoid valve 7 and a flow sensor 8 are sequentially inserted into the pipe 3 connecting the branch valve plug 2 and the heat exchanger 9 . A pump 11 and a buffer tank 12 are inserted into the piping 10 connecting the heat exchanger 9 and the human body switching valve 13 .

The rear nozzle 21 of the nozzle part 20, the bidet nozzle 22, and the nozzle cleaning nozzle 23 are respectively connected to a plurality of ports of the switching valve 13 for a human body.

The vacuum breaker 31 is connected to the branch pipe 30 extending from the pipe 3 between the water stop solenoid valve 7 and the flow sensor 8 , and is arranged above the heat exchanger 9 and the flush water outlet of the toilet nozzle 40 . One end of the branch pipe 32 is connected to the vacuum interrupter 31 . The branch pipe 30 and the branch pipe 32 are connected by a vacuum breaker 31 . The other end of the branch pipe 32 is connected to the toilet nozzle 40 . The toilet nozzle motor 40m and the lamp 50 are installed near the toilet nozzle 40 . The vacuum breaker 61 is provided in the buffer tank 12 and arranged above the heat exchanger 9 . In addition, the vacuum interrupter 61 and the buffer tank 12 are integrally formed. Therefore, the buffer tank 12 is also arranged above the heat exchanger 9 .

Next, the flow of washing water in the main body unit 200 and the control of each component unit of the main body unit 200 by the control unit 90 will be described.

The clean water flowing through the water pipe 1 is supplied to the filter 4 through the branch valve plug 2 as washing water. As a result, the filter 4 removes garbage, impurities, and the like contained in the washing water.

Next, the backflow of the washing water in the pipe 3 is prevented by the check valve 5 , and the flow rate of the washing water flowing in the pipe 3 is maintained constant by the constant flow valve 6 . Then, the supply state of the washing water to the heat exchanger 9 is switched by the water stop solenoid valve 7 . The operation of the water stop solenoid valve 7 is controlled by the control unit 90 .

In the piping 3 , the flow sensor 8 measures the flow rate of the washing water flowing in the piping 3 , and supplies the measured flow rate value to the control unit 90 . The heat exchanger 9 heats the washing water supplied through the pipe 3 to a predetermined temperature. The control unit 9 controls the operation of the heat exchanger 9 based on the measured flow rate value measured by the flow sensor 8 .

Next, the washing water heated by the heat exchanger 9 is pumped by the pump 11 to the switching valve 13 for the human body through the buffer tank 12 . The operation of the pump 11 is controlled by the control unit 90 .

The buffer tank 12 functions as a temperature buffer of the heated washing water. This suppresses occurrence of temperature unevenness in the washing water that is pressure-fed to the switching valve 13 for the human body. In addition, the total capacity of the heat exchanger 9 and the buffer tank 12 is preferably 15 cc to 30 cc, more preferably 20 cc to 25 cc.

That is, the branch pipe 30 and the branch pipe 32 function as a wastewater circuit. Details of the toilet nozzle 40 will be described later.

In addition, in this example, a vacuum breaker 31 is provided between the heat exchanger 9 and the toilet 40 , and a vacuum breaker 61 is provided between the heat exchanger 9 and the nozzle unit 20 . Thereby, the washing water in the heat exchanger 9 can be prevented from flowing out to the outside through the branch pipe 30 , the branch pipe 32 , and the toilet nozzle 40 , and to the outside through the pipe 10 and the nozzle unit 20 . As a result, empty firing of the heat exchanger 9 can be prevented.

In addition, the vacuum breaker 31 prevents sewage and the like from flowing backward from the toilet nozzle 40 side, and the vacuum breaker 61 prevents sewage and the like from flowing backward from the nozzle unit 20 side.

In addition, since the buffer tank 12 and the vacuum interrupter 61 are integrally provided, the main body 200 can be downsized. In addition, since the cold water in the buffer tank 12 is discharged by the vacuum breaker 61, it is possible to prevent cold water from being sprayed out from the buttock nozzle 21 when washing the buttocks.

<4> Structure and action of the toilet nozzle

(4-a) Explanation of the toilet nozzle

Next, the toilet nozzle 40 will be described. FIG. 4 is a longitudinal sectional view of the sanitary cleaning device 100 . As shown in FIG. 4 , the toilet nozzle 40 is disposed at the lower portion of the main body 200 close to the nozzle portion 20 , and its front end is located inside the toilet 700 . A lamp 50 made of LED (Light Emitting Diode) or the like is provided near the toilet nozzle 40 .

In addition, as shown in FIG. 4 , each part will be described below with the main body part 200 side of the sanitary cleaning device 100 being the rear and the front end side of the toilet seat part 400 being the front.

A toilet nozzle cover 40K is provided so as to cover the front side of the toilet nozzle 40 and the lamp 50 provided in the vicinity thereof. The toilet nozzle cover 40K is formed of transparent resin. Thus, when the lamp 50 emits light, the light is irradiated to the inside of the toilet 700 through the toilet nozzle cover 40K.

FIG. 5 is an enlarged cross-sectional view for explaining the structure of the nozzle 40 of FIG. 4 and its surroundings. As shown in FIG. 5 , the toilet nozzle 40 has a structure in which a rod-shaped jet flow forming member 42 is inserted into the front end portion of a cylindrical toilet nozzle body portion 41 . Inside the toilet nozzle body 41 , a gap is formed between the inner surface of the toilet nozzle body 41 and the outer peripheral surface of the jet flow forming member 42 . A connection pipe 44 constituting a part of the branch pipe 32 in FIG. 3 is connected to the rear end portion of the toilet nozzle main body 41 .

Thus, when the cleansing water (waste water) is supplied from the connecting pipe 44 (branch pipe 32 ) to the toilet nozzle main body 41 , the cleansing water passes through the gap between the inner surface of the toilet nozzle main body 41 and the outer peripheral surface of the jet flow forming member 42 . The gap is sprayed from the front end of the toilet nozzle 40 .

One end of the rotating piece 43 is fixed to the rear end of the toilet nozzle main body 41 . The other end of the rotating piece 43 is connected to the toilet nozzle motor 40m fixed to 200 A of main body lower casings mentioned later. Thereby, when the toilet nozzle motor 40m operates, the front-end|tip part of the toilet nozzle main body part 41 rotates.

Here, when the toilet nozzle 40 is on standby, that is, when the user does not enter the toilet, the front end of the toilet nozzle 40 is positioned so as to approach the inner surface of the toilet nozzle cover 40K. Hereinafter, the position of this toilet nozzle 40 is called a storage position. In addition, the position where the toilet nozzle 40 is moved downward and the toilet cleansing is performed becomes a protruding position below.

Under the situation that toilet nozzle 40 is also used as the outlet of waste water, if toilet nozzle 40 becomes the state that is fixed in the position of toilet cleaning, then always spray the spray stream of toilet cleaning in the process of user's defecation, in use Create discomfort. Therefore, in this case, countermeasures such as pressing the nozzle to the storage position by the user by hand are required.

In FIG. 5 , one end of the rotating piece 43 is fixed to the rear end of the toilet nozzle main body 41 . The other end of the rotating piece 43 is connected to the toilet nozzle motor 40m fixed to 200 A of main body lower casings mentioned later. Thereby, when the toilet nozzle motor 40m operates, the front-end|tip part of the toilet nozzle main body part 41 rotates. Furthermore, the torsion spring 40S is inserted into the rotating piece 43, and the torsion spring 40S is used as a fixing part by using the fixing part 43a provided on the rotating piece 43 and the fixing groove 40Kb provided on the toilet nozzle cover 40K, and the toilet nozzle body part 41 is accommodated toward the nozzle. Apply force to one side of the position. There is looseness of the drive system between the toilet nozzle motor 40m and the rotary plate 43. In addition, when the toilet nozzle motor 40m uses a reduction gear, there is a backlash of the reduction gear. Therefore, even if the toilet nozzle main body 41 is manually moved to The storage position does not stop at the storage position, and the toilet nozzle main body portion 41 is returned only by the amount of looseness. If the toilet nozzle main body 41 is urged toward the nozzle storage side by the torsion spring, the looseness is absorbed by the torsion spring, so that the nozzle main body 41 can be fixed at a predetermined storage position by manual operation.

The torque of the torsion spring 40S is set to be equal to or greater than the tension generated by the pipe 44 connected to the toilet nozzle body 41 , so that the toilet nozzle body 41 can be easily set on the nozzle storage side.

(4-b) Other structural examples of toilet nozzles (measures when the nozzle stops at the middle position)

In the case where the toilet seat cannot be cleaned with warm water, and the toilet nozzle is stopped at the middle position, and the jet stream is sprayed out, there is a possibility that the jet stream flies out of the toilet and the water leaks on the floor, so no matter where the toilet nozzle stops , it needs to be configured so that at least water does not fly out of the surface of the toilet.

In FIG. 5 , for the toilet nozzle cover 40K, the jet flow ejected by the rotation of the front end portion of the toilet nozzle main body 41 does not fly out from the surface of the toilet while the jet flow is moved from the distribution position to the storage position. 40 ka of shielding parts which comprise 40 K of nozzle covers. Thereby, no matter where the toilet nozzle main body part 41 stops, the jet flow does not fly out of the toilet, and water leakage can be prevented.

Also, when the nozzle cover 40K covers the toilet nozzle 40 and an external force acts on the toilet nozzle 40, since the toilet nozzle 40 moves to the inside of the shielding portion of the nozzle cover 40K, no overload is applied to the toilet nozzle by the external force.

In this case, when the entry detection sensor 600 of FIG. 1 detects that the user enters the toilet, the toilet nozzle motor 40m operates. Thereby, the front-end|tip part of the toilet nozzle 40 rotates in the direction shown by the arrow A of FIG. 5. As shown in FIG. Then, the above-mentioned toilet pre-washing starts.

FIG. 6 is a longitudinal sectional view of sanitary cleaning device 100 during toilet pre-cleaning, and FIG. 7 is an enlarged sectional view illustrating the structure of toilet nozzle 40 and its surroundings in the state shown in FIG. 6 .

First, as shown in FIGS. 6 and 7 , it is detected that the user enters the toilet. When the front end of the toilet nozzle 40 rotates, the front end moves below the toilet nozzle cover 40K and is exposed in the inner space of the toilet 700. position. Hereinafter, the position of the toilet nozzle 40 is referred to as a toilet cleaning position.

In this state, cleansing water is supplied from the connection pipe 44 to the toilet nozzle main body 41 . As a result, the cleansing water is sprayed from the front end of the toilet nozzle 40 .

The cleansing water sprayed from the toilet nozzle 40 is sprayed radially in a direction substantially perpendicular to the axis of the toilet nozzle 40 .

Thereby, as shown in FIG. 6 , the washing water is sprayed over a wide range of the inner surface centering on the disposal port 700D of the vessel 700 . Therefore, when the user enters the toilet, the inner surface of the dry toilet 700 is wetted with cleansing water.

In addition, at this time, the lamp 50 is illuminated so that the user can observe that the toilet pre-washing is being performed.

As described above, the inner surface of the toilet 700 before use is wetted, so that dirt can be prevented from adhering to the inner surface of the toilet 700 .

In addition, as will be described later, the toilet pre-cleaning operation is stopped when the user sits down on the toilet seat 400 or the user operates the remote control device 300 after a predetermined time has elapsed.

When the toilet pre-washing is completed, the toilet nozzle motor 40m is activated again. Thereby, the front-end|tip part of the toilet nozzle 40 moves to the inside of the toilet nozzle cover 40K again, and approaches the inner surface of the toilet nozzle cover 40K. That is, after the toilet pre-washing, the toilet nozzle 40 moves to the storage position again. At this time, the cleansing water continues to be sprayed from the front end of the toilet nozzle 40 . So start the toilet backwash.

When cleaning the rear of the toilet, as indicated by arrows B and C in FIG.

Accordingly, when the user uses the toilet device 1000 , it is possible to reliably prevent dirt from adhering to the rear inner surface of the toilet 700 .

In addition, at this time, the cleansing water sprayed from the toilet nozzle 40 toward the inner surface of the toilet nozzle cover 40K collides with the inner surface of the toilet nozzle cover 40K and splashes to the front end of the toilet nozzle 40 . Thereby, the front-end|tip part of the toilet nozzle 40 is cleaned, and the contamination of the front-end part of the toilet nozzle 40 is prevented.

Afterwards, for example, the user stands up from the toilet seat 400, and the toilet back washing stops. That is, the spraying of cleansing water from the toilet nozzle 40 is stopped.

(4-b) Details of the structure of the toilet nozzle

Here, details of the structure of the tip portion of the toilet nozzle 40 will be described. FIG. 8 is a cross-sectional view showing the structure of the tip portion of the toilet nozzle 40 of FIG. 4 . FIG. 8( a ) shows a longitudinal cross-sectional view of the front end portion of the toilet nozzle 40 , and FIG. 8( b ) shows a cross-sectional view along line C14-C14 of FIG. 8( a ).

As shown in FIG. 8( a ), the jet flow forming member 42 is inserted from the front end opening 41 h of the toilet nozzle main body 41 into the inside. The jet flow forming member 42 has an insertion shaft portion 42a. As shown in FIG. 8( b ), three blade members 42 b extending radially outward from the axis center are formed on the insertion shaft portion 42 a. A large-diameter portion 42c, an enlarged portion 42d, and a flange portion 42e are formed from the vane member 42b toward the front end portion of the jet flow forming member 42 .

The diameter of the large diameter part 42c is larger than the diameter of the insertion shaft part 42a. In addition, the enlarged portion 42d further gradually expands in diameter toward the front end portion of the jet flow forming member 42 which is larger in diameter than the front end opening 41h. Moreover, the outer diameter of the flange part 42e is larger than the outer diameter of the toilet nozzle main body part 41. As shown in FIG.

A step portion 41 d is formed on the inner surface of the toilet nozzle main body portion 41 . When the jet flow forming member 42 is inserted into the toilet nozzle main body 41 , the stepped portion 41 d abuts against the blade member 42 b of the jet flow forming member 42 . At this time, the blade member 42b functions as a spacer between the jet flow forming member 42 and the toilet nozzle main body portion 41 . Accordingly, the jet flow forming member 42 is positioned inside the toilet nozzle main body 41 .

In this state, the large-diameter portion 42c of the jet flow forming member 42 protrudes from the front end opening 41h of the toilet nozzle body 41 , and the enlarged portion 42d and the flange portion 42e are located outside the toilet nozzle body 41 .

The outer diameters of the insertion shaft portion 42 a and the large diameter portion 42 c are smaller than the inner diameter of the toilet nozzle body portion 41 . Therefore, a gap is formed between the inner surface of the toilet nozzle main body 41 and the outer peripheral surface of the jet flow forming member 42 as described above. This gap serves as a flow path 41s for washing water.

When the cleansing water is supplied from the connecting pipe 44 in FIG. 5, the cleansing water passes through the flow path 41s, passes through the accelerating flow path 41t constituted by the large-diameter portion 42c and the toilet nozzle body 41, and the flow is accelerated to a set flow velocity, and the flow in the enlarged portion The flow of 42d is deflected and spreads over the entire circumference of the flange portion 42e to form a radial jet flow from the flange portion end 42f.

Therefore, the cleansing water is sprayed radially in a direction substantially perpendicular to the axis of the toilet nozzle 40 .

The velocity for expanding the toilet surface as the jet flow is 4m/sec. In order to realize this velocity, if the diameter of the large-diameter portion 42c inserted into the shaft portion 42a is set to 4mm and the cleaning flow rate is set to 1L/min, the accelerated flow The flow path width of the path 41t is a narrow flow path of about 0.3 mm.

(4-c) Details of other structures of the toilet nozzle (floating support of the jet flow forming member)

FIG. 9 is a cross-sectional view showing another embodiment of the toilet nozzle 40 . In the embodiment shown in FIG. 8 , the vane member 42b contacts the toilet nozzle main body 41, and the large-diameter portion 42c is supported coaxially with the toilet nozzle main body 41. However, in this embodiment, the vane member 42j and the toilet nozzle main body A predetermined gap (about 0.05 mm) is provided between the parts 41 . In the state where the jet flow is ejected from the toilet nozzle 40, the pressure distribution of the flow passage cross section of the acceleration passage 41t is constant as long as the passage width of the acceleration passage 41t is the same, but when the acceleration passage 41t When the flow path width is different, pressure distribution occurs, and the pressure becomes higher at the place where the flow path width is narrow. If a predetermined gap (about 0.05 mm) is provided between the vane member 42j and the toilet nozzle main body 41, and the vane member 42j is provided as a floating support in a structure that can freely move by the force acting on the vane member 42j, then it is possible to utilize the The pressure of the fluid in the passage 41t is automatically corrected at the place where the channel width is narrow to widen the channel width, and it is actually considered that the automatic correction works by the operation of the toilet nozzle.

The blade member 42j can be in contact with the toilet nozzle main body 41, and the large-diameter part 42c can be coaxially supported by the toilet nozzle main body 41. structure that alleviates these precision management conditions.

In order to suppress inclination of the insertion shaft portion 42a after realizing this floating support structure, the length of the blade member 42K in the axial direction is preferably approximately the entire length of the insertion shaft portion 42a as shown in FIG. 10 .

Moreover, as shown in FIG. 11, by providing the blade member 42m only in the vicinity of the both ends of the insertion shaft part 42a, the effect of suppressing inclination similarly to the case where it is provided over the whole length can be acquired. Furthermore, by shortening the length of the blade member 42m, the control range of the size of the blade member 42 can be reduced, and productivity can be improved.

(4-d) Details of other structures of the toilet nozzle (stabilization of the flow of the inserted shaft part)

Another embodiment of the toilet nozzle is shown in FIG. 11 . The insertion shaft portion 42a is provided with a rectification portion 42g which is an annular protrusion exhibiting a rectification effect in the flow path 41s. Sometimes the water flowing in from the connecting pipe 44 of the toilet nozzle 40 has a deflected flow due to the direction of inflow, and if the deflected flow is kept constant, the expansion of the jet flow is also deflected when it reaches the front end of the toilet nozzle 40 . The flow can be rectified by the rectification part 42g provided in the vicinity of the connection pipe 44, and the same expanded jet flow can be obtained.

(4-e) Attachment and detachment structure of jet flow forming parts

10 and 11 show the detachable jet flow forming member 42 , and FIG. 12 shows a cross-sectional view of a state in which the jet flow forming member 42 is inserted into the toilet nozzle body 41 .

When the user cleans the toilet nozzle 40 itself, the jet flow forming member 42 that is most likely to get dirty can be attached and detached. The insertion shaft portion 42a constitutes a claw portion 42h at the rear, and as shown in FIG. 12 , engages with a step portion 41e provided in the toilet nozzle main body portion 41 to stop.

About this claw part 42h, it is preferable to provide the reinforcement rib 42i etc. in order to raise strength.

By making the jet flow forming member 42 a detachable structure, the user can easily pull out the insertion shaft portion 42a and perform cleaning.

(4-f) Spray flow rate of cleaning water during toilet pre-washing

FIG. 13 is a graph showing the relationship between the spray flow velocity and the expansion width of the cleansing water sprayed from the toilet nozzle 40 in FIG. 4 .

First, the discharge flow rate and the expansion width will be described. FIG. 13( a ) shows a diagram for explaining the definition of the discharge flow rate and the expansion width.

In FIG. 13( a ), a state in which cleansing water is sprayed from the toilet nozzle 40 arranged such that the axis is parallel to the vertical direction is shown.

Here, the ejection flow rate refers to the flow rate of cleansing water ejected from the front end portion of the toilet nozzle 40 in the horizontal direction as indicated by arrow WV. In addition, the expansion width means the outer diameter of the area|region to which wash water is supplied 100 mm downward from the toilet nozzle 40, as shown by arrow WW.

FIG. 13( b ) shows the experimental results when washing water is sprayed from the toilet nozzle 40 . In FIG. 13( b ), the vertical axis represents the widening width WW of the washing water, the horizontal axis represents the jetting flow velocity of the washing water, and the solid line shows the relationship between the widening width WW and the jetting flow rate.

As shown in FIG. 13( b ), when the jet flow velocity of the washing water is set higher than 2 m/s, the expansion width becomes larger than 200 mm. In this case, since the cleansing water can be supplied to a sufficiently wide area of the inner surface of the toilet 700 , it is possible to sufficiently prevent dirt from adhering to the inner surface of the toilet 700 .

In addition, when the jetting flow velocity of the washing water is set to be smaller than 10 m/s, the expansion width is smaller than 1000 mm. In this case, it is possible to prevent the washing water from being scattered to the outside of toilet 700 . In addition, by making the jetting flow velocity of the washing water smaller than 10 m/s, it is possible to prevent the washing water jetted from the toilet nozzle 40 from splashing largely on the inner surface of the toilet 700 . Therefore, it is possible to sufficiently prevent the washing water from being scattered to the outside of toilet bowl 700 .

Therefore, by setting the spraying speed of the cleansing water in the range of 2 m/s to 10 m/s, it is possible to sufficiently prevent the cleansing water from scattering outside the toilet 700 and to sufficiently prevent dirt from adhering to the toilet 700 . In addition, it is more preferable to set the spraying speed of the washing water within a range of 4 m/s to 8 m/s. In this case, it is possible to reliably prevent dirt from adhering to the toilet 700 while sufficiently preventing the washing water from splashing out of the toilet 700 .

(4-g) Action timing and control flow of toilet pre-cleaning

In this example, when the user enters the restroom, the toilet pre-washing is started under the control of the control unit 90 . In addition, when the user uses the toilet device 1000 , the toilet rear part is cleaned under the control of the control unit 90 . That is, when the user sits on the toilet seat 400 ( FIG. 1 ), the washing water is prevented from splashing forward from the toilet nozzle 40 ( FIG. 1 ). Therefore, it is possible to prevent washing water from adhering to the user.

The control unit 90 performs transition from the toilet pre-cleaning to the toilet rear washing based on the elapse of a predetermined time, the user sitting on the toilet seat 400 , or the user's operation of the remote control device 300 .

Here, the predetermined time is determined in advance based on the average time from when the user enters the bathroom to when the user sits down on the toilet seat 400 . Therefore, in order to determine the predetermined time, the present inventors investigated the time from when the user enters the restroom to when he sits down on the toilet seat 400 (hereinafter referred to as room entry and seating time). This survey was conducted by measuring the entry and sitting time of each user when a predetermined number of users use the restroom, and calculating the cumulative percentage for each entry and sitting time.

FIG. 14 is a diagram showing the results of a survey of time to enter a room and sit down. In FIG. 14 , the horizontal axis represents the room entry and sitting time, and the vertical axis represents the cumulative percentage of users.

As shown in FIG. 14 , according to this survey, most users (more than 90% of users) sit on the toilet seat 400 after about 6 seconds after entering the bathroom. Therefore, in this example, the above-mentioned predetermined time is set to 6 seconds. In this case, the transition from the toilet pre-wash to the toilet back-wash can be performed immediately before the user sits on the toilet seat 400 . Thereby, the inner surface of the toilet 700 can be fully wetted before the user sits down, and the cleansing water sprayed from the toilet nozzle 40 can be reliably prevented from adhering to the user.

Next, a control flow of the toilet cleaning process (toilet pre-cleaning and toilet rear cleaning) by the control unit 90 ( FIG. 3 ) will be described.

FIG. 15 is a diagram showing a control flow of the toilet cleaning process by the control unit 90 .

As shown in FIG. 15 , the control unit 90 first controls the toilet nozzle motor 40m ( FIG. 3 ) to hold the toilet nozzle 40 at the stored position (the position shown in FIGS. 4 and 5 ) (step S1 ).

Next, the control part 90 judges based on the output signal of the room entry detection sensor 600 (FIG. 1) whether a user enters a toilet (step S2). When the user enters the toilet, the control unit 90 controls the toilet nozzle motor 40m to move the toilet nozzle 40 to the toilet cleaning position (position shown in FIGS. 6 and 7 ) (step S3 ).

Next, the control unit 90 controls the water stop solenoid valve 7 ( FIG. 3 ) and the switching valve motor 13m ( FIG. 3 ) to spray cleansing water from the toilet nozzle 40 and light the lamp 50 (step S4 ).

Next, the control part 90 judges whether predetermined time (for example, 6 seconds) has passed after a user entered a bathroom (step S5). When the predetermined time has not elapsed, the control unit 90 determines whether or not the user has pressed the stop switch 311 ( FIG. 2 ) (step S6 ).

When the stop switch 311 is not pressed, the control unit 90 determines whether the user is seated on the toilet seat 400 ( FIG. 1 ) based on the output signal of the seating sensor 610 ( FIG. 1 ) (step S7 ). When the user does not sit on the toilet seat 400, the control part 90 returns to the process of step S5.

When it is determined in step S5 that the predetermined time has elapsed, the control unit 90 turns off the lamp 50 (step S8). Next, the control part 90 controls the toilet nozzle motor 40m (FIG. 3), and moves the toilet nozzle 40 to a storage position (position shown in FIG. 4 and FIG. 5) (step S9).

Next, the control unit 90 determines whether or not the user stands up based on the output signal of the seating sensor 610 ( FIG. 1 ) (step S10 ). When it is determined that the user has stood up, the control unit 90 controls the water stop solenoid valve 7 ( FIG. 3 ) and the like to stop the flushing water from the toilet nozzle 40 (step S11 ). Thereby, the toilet cleaning process by the control part 90 is complete|finished.

When it is determined in step S2 that the user has not entered, the control unit 90 waits until the user enters.

When the user presses the stop switch 311 in step S6, or when the user sits down on the toilet seat 400 in step S7, the control part 90 performs the process of step S8.

When the user does not stand up in step S10, the control unit 90 waits until the user stands up.

As described above, in this example, the toilet pre-washing is completed after a predetermined time elapses after the user enters the restroom. In this case, as described above, the inner surface of the toilet 700 can be sufficiently wetted before the user sits down, and the cleansing water sprayed from the toilet nozzle 40 can be reliably prevented from adhering to the user.

In addition, when the user presses the stop switch 311 or the user sits down on the toilet seat 400, the toilet pre-washing ends. Therefore, even when the user sits on the toilet seat 400 within the predetermined time, it is possible to prevent the cleansing water sprayed from the toilet nozzle 40 from adhering to the user.

In addition, when the user sits on the toilet seat 400, toilet rear washing is performed. Therefore, it is possible to reliably prevent dirt from adhering to the rear side of the inner surface of the toilet 700 .

In addition, in the control flow of FIG. 15 , after the toilet nozzle 40 moves to the toilet cleaning position in step S3, the spraying of cleaning water starts in step S4, but it may also be before the toilet nozzle 40 moves to the toilet cleaning position, that is, before the toilet cleaning position. Spraying of washing water starts while being held at the storage position. In this case, the toilet nozzle 40 can be cleaned before the toilet pre-wash is performed. Therefore, contamination of the toilet nozzle 40 can be reliably prevented.

In addition, in the control flow of FIG. 15, the toilet nozzle 40 is moved to the toilet cleaning position when the user's entry is confirmed in step S2, but the toilet nozzle 40 may be made to stand by at the toilet cleaning position in advance. In this case, the toilet pre-washing can be quickly started, so that a sufficient amount of washing water can be supplied to the toilet 700 . Thereby, it is possible to reliably prevent dirt from adhering to the toilet 700 . In addition, when the toilet nozzle 40 is made to stand by at the toilet cleaning position in advance, for example, the toilet nozzle 40 may be moved to the toilet cleaning position when a predetermined time elapses after the user finishes using the toilet device 1000 .

In addition, when the cleansing water is sprayed from the toilet nozzle 40 , the supply of the cleansing water to the nozzle unit 20 ( FIG. 3 ) may be stopped by controlling the human body switching valve 13 . In this case, since a sufficient amount of cleansing water can be supplied to toilet nozzle 40 , toilet 700 can be sufficiently soaked with cleansing water. As a result, it is possible to sufficiently prevent dirt from adhering to the toilet 700 .

(4-h) About the effect of toilet cleaning and toilet nozzle

As described above, in the present embodiment, before the user sits on the toilet unit 400 , pre-washing of the toilet is performed. Thereby, substantially the entire inner surface of the toilet 700 can be soaked with the cleansing water, so that dirt can be prevented from adhering to the toilet 700 .

In addition, a predetermined gap (about 0.05 mm) is provided between the vane member 42j of the toilet nozzle 40 and the toilet nozzle main body 41, and the vane member 42b is freely movable by the force acting on the vane member 42b. The unevenness of the flow path width is automatically corrected by the pressure of the fluid passing through the acceleration flow path 41t, so that the jet flow can spread uniformly on the surface of the toilet.

In addition, the insertion shaft portion 42a is provided with an annular protrusion 42g that exerts a rectification effect in the flow path 41s, so that the flow of water flowing in from the connecting pipe 44 of the toilet nozzle 40 is rectified so that the jet flow can be evenly distributed in the toilet. Expand in the face.

In addition, since the jet flow forming member 42 has a detachable structure, the user can easily pull out the jet flow forming member 42 for cleaning, and thus the toilet nozzle 40 can be kept clean.

In addition, in this embodiment, the structure in which all the vane members are provided on the outer surface of the jet flow forming member is described, but it is not limited to this structure, and even the structure in which the vane members are provided on the inner surface of the toilet nozzle main body may be used. to get the same effect. Furthermore, the vane member may be provided on both the outer surface of the jet flow forming member and the inner surface of the toilet nozzle main body. The selection of each of these structures is determined by considering the workability and strength of each member, and in this embodiment, the vane member is provided on the outside of the jet flow forming member in consideration of workability.

Based on the above description, many improvements and other implementations of the present invention will be known to those skilled in the art. Therefore, the above description is explained as an example only, and is provided for the purpose of demonstrating the best mode for carrying out the present invention to those skilled in the art. Details of its construction and/or function may be substantially changed without departing from the spirit of the invention.
