Abstract

A water control tubular portion (150) is fixed to the forward end of a discharge hose body (14). The water control tubular portion is a tubular body or an inverted funnel-like (trumpet-like) tubular body and has water control sections inside it. The water control sections are arranged zigzag so that the amount of discharge of an object (e.g. sewage) becomes as constant as possible and the speed of the discharge can be made slackened. Since the amount of discharge of the object from the forward end of the discharge hose body becomes substantially constant by the water control tubular section (150) and the speed (flow speed) of the discharge is slackened, the forward end of the discharge hose is not fluttered by the pressure of a fluid object (sewage) sent under pressure from a simple toilet device.

Specification

Exhaust hose and toilet system using it

Technical field

[0001] The present invention relates to a discharge hose in which a water control cylinder is provided at the end of a discharge hose main body, thereby eliminating a shake or the like of the discharge hose main body generated at the time of discharge of a pumped delivery. The present invention also relates to a toilet system that prevents the transported waste from being scattered in the toilet bowl. Background art

[0002] A portable simplified toilet device has been developed for elderly people who need nursing care and for people who are physically incapacitated and it is difficult to go to the existing toilet in the room.

[0003] This portable type portable toilet device is configured in a chair type so as to be able to be installed indoors, and can sit on the chair and add it. The portable type portable toilet equipment is equipped with a water supply hose for flushing the toilet bowl, a discharge hose for discharging the waste, and a means for pumping the waste. And the water supply and discharge are done using existing toilets

[0004] A toilet system for treating waste in the portable type portable toilet apparatus using the existing toilet as described above can be configured, for example, as shown in FIG.

The toilet system shown in FIG. 20 is an example in which the existing toilet 3 is installed facing the corridor 2 of the house 1. A toilet 4 and a flush tank 5 for cleaning are installed in the existing toilet 3. In this example, a room 6 is located as a bedroom along the corridor 2 and, for example, a bed 7 is placed in the room 6. A portable toilet device 10 is placed in part of the room 6, and it is possible to add a service by the toilet device 10 without going to the existing toilet 3.

The portable simple toilet apparatus 10 is a flush toilet. Therefore, water supply means and discharge means are provided, the water supply hose 12 as the water supply means is connected to the water supply, and the discharge hose 14 as the discharge means is led to the existing toilet 4.

Although the discharge hose 14 can be connected to a sewer pipe, doing so requires piping work, which increases the cost. In the case where the existing toilet 4 is provided with a connection for the discharge hose 14 as well, since the toilet must be remodeled or a new toilet must be prepared, the cost is also increased. Figure The reference numeral 20 is one in which the existing toilet 4 can be used as it is.

When the existing toilet 4 is used as it is, the tip of the discharge hose 14 is connected, for example, as shown in FIG. In this example, the discharge hose 14 is threaded through the space between the existing toilet bowl 4 obtained by the pedestal 118a provided on the lower surface of the toilet seat 118. In the existing toilet 4, a simple hose clamp 120 is attached to the toilet seat 118. Although the tip 14b of the discharge hose 14 is free, it can be fixed to the inside of the existing toilet 4 as well.

Disclosure of the invention

Problem that invention tries to solve

[0009] By the way, if the discharge hose 14 is installed by using the existing toilet 4 as it is as shown in FIG. 21, there is a risk that dirt will stagnate in the discharge hose 14 only by the water pressure of the washing water. As the apparatus 10, it is desirable to be a pumping type flush toilet.

[0010] When configured as a pumping type, the discharge hose 14 receives a certain delivery pressure S, so when the waste is discharged from the discharge hose 14, this delivery pressure irregularly displaces the tip 14b of the discharge hose 14 There is a risk that they may go wild. If the tip end portion 14b is shaken, there is a risk that dirt will scatter into the existing toilet 4 and this is not preferable for hygiene.

[0011] It is conceivable that the tip 14b is fixed in the existing toilet 4 or that the tip 14b may be submerged in the stagnant water (washing water) of the existing toilet 4. Even in such a case, the speed at which the waste is discharged is Because it is unexpectedly fast, it is not possible to effectively suppress filth scattering.

[0012] Therefore, the present invention solves such conventional problems, and in particular, proposes a discharge hose capable of effectively suppressing discharge material discharge and a toilet system using the same.

Means to solve the problem

[0013] In order to solve the above-mentioned problems, the discharge hose according to the present invention described in claim 1 has a hose main body,

It consists of a water control cylinder attached to the tip of this hose body,

This water control cylinder part is characterized in that a plurality of water control pieces arranged in a zigzag form are provided inside thereof.

[0014] The toilet system according to the present invention described in claim 3 is an existing toilet and a portable type Composed of easy toilet equipment,

The simple toilet equipment is connected with a discharge hose for waste discharge,

The water control cylinder attached to the tip of the discharge hose is characterized in that it is fixed inside the toilet through the space between the toilet of the existing toilet and the toilet seat.

In the present invention, the water control cylinder portion is attached to the tip of the discharge hose main body. The water control cylinder portion is provided to limit the discharge rate and discharge rate (flow rate) of the discharge (such as dirt) discharged from the tip of the discharge hose main body. The water control cylinder part is a cylindrical body or a reverse funnel-like (lapper-like) cylinder, and a plurality of water control pieces are provided inside.

The water control pieces are arranged in a staggered manner so that the discharge rate can be made as constant as possible and the discharge speed can be reduced. However, the length and width of the water control pieces, the arrangement interval and number of water control pieces, etc. are selected so as not to hinder the discharge of the discharge material.

The water control piece can reduce the flow speed (flow velocity) of the flow-like material at the tip opening of the water control cylinder and disperse the internal pressure, so that the flow-like material is pumped. Also, in the decelerated state, it is possible to discharge the flowable material by a substantially constant amount. Since the internal pressure can be reduced, the tip end of the discharge hose will not go out of control by the reaction force of the discharge pressure of the fluid, and scattering of the fluid can be avoided.

Therefore, if this discharge hose is applied between a portable toilet device for constructing a toilet system and an existing toilet, the waste may be scattered throughout the existing toilet even if it is pumped. It's gone and it's hygienic.

The portable type portable toilet device is a pumping type flush toilet. The simplified toilet apparatus includes a water supply port to which wash water is supplied from the vicinity of the opening of the toilet bowl, a reservoir provided at the back of the opening, and a discharge port communicating with the reservoir. Have.

[0020] In the reservoir portion, a means for crushing waste is attached. Above the reservoir portion, there is provided a crushed material pumping means for pressure-feeding the powder of the soil, and further, an open / close lid for sealing the reservoir portion is provided above the crushed material pumping means. On the outlet side of the toilet bowl, an on-off valve (discharge solenoid valve) is provided.

When dirt or the like falls on the open / close lid, the weight causes the tip of the lid to separate from the edge of the reduced-diameter portion, and the dirt automatically drops into the accumulation portion under its own weight. Open and close lid after defecation Automatically close, and the reservoir is automatically sealed again. Deodorizing from dirt and concealing means of grinding can be done.

[0022] The pulverizing means is driven to pulverize the dirt. After waste treatment, compressed air is sent into the reservoir to pressurize the reservoir (about 2 atm). After that, by opening the discharge solenoid valve, the pulverized material is fed to the existing toilet side through the discharge hose. By this pumping process, the fluid can be discharged to the existing toilet without staying in the discharge hose.

[0023] If the water supply hose for cleaning water supplied to the simple toilet apparatus and the above-mentioned discharge hose are integrated, the installation, removal and routing of these hoses become easy.

Effect of the invention

In the present invention, a discharge hose provided with a water control cylinder portion is provided. The present invention also provides a toilet system provided with such a discharge hose.

According to this, since the discharge amount and discharge speed of the flow-shaped material can be suppressed by the water control cylinder portion, it is possible to avoid that the tip portion of the discharge hose runs wild when discharging the flow-shaped material. Therefore, in the toilet system equipped with this discharge hose, it is possible to suppress the runaway of the end of the discharge hose when discharging the waste into the existing toilet bowl, so a sanitary toilet system can be provided.

BEST MODE FOR CARRYING OUT THE INVENTION

[0027] Subsequently, preferred embodiments of the discharge hose and the toilet system using the same according to the present invention will be described in detail with reference to the drawings. The portable type portable toilet apparatus applicable to the present invention is particularly preferably a so-called portable toilet apparatus with a so-called warm-water-washed toilet seat with a butt-cleaning function. The following explanation omits the explanation about the facilities of this warm water washing toilet seat. The portable type portable toilet device is applied to a Western-style flush toilet.

Example 1

As shown in FIG. 20, the toilet system according to the present invention is constructed by the existing toilet 3 and the portable type portable toilet device 10, and the water supply hose 12 and the discharge hose 14 connecting between them. Since the configuration of FIG. 20 has already been described, its details will be omitted. The existing toilet 3 is also a Western-style flush toilet. The portable type portable toilet device 10 is a pumping type flush toilet.

FIG. 1 is a cross-sectional view of an essential part showing an example of a pumping type portable type portable toilet device 10 applicable to the present invention. The portable toilet device 10 has a toilet body 20. The toilet body 20 has a funnel-like cross-sectional shape substantially the same as a normal flush toilet (Western-style toilet), but the overall shape is configured as a box. In recent years, there is a strong demand for interior elements as well, and not only box-type but chair-type ones with an armrest are also used.

[0030] In order to reduce the weight of the toilet body 20, the toilet body 20 in this example is a plastic molded product, but may be molded using other materials such as pottery. Upper opening of the toilet bowl 20 A toilet seat 21 is located on the side, and a toilet lid 23 is provided so as to close the toilet seat 21 and the upper opening.

[0031] The bottom of the toilet body 20 becomes a reservoir 18 for trap water (pool water) and dirt.

A discharge portion 22 communicating with the reservoir portion 18 and having a substantially H-shaped cross section is provided, and a discharge hose 14 is connected to the discharge port 27 according to the present invention.

[0032] The cross-section generally in the shape of a letter "H" is often generally referred to as an S-shaped trap. Therefore, in this example, the back surface 20b of the toilet body 20 is provided with the connecting portion 26, and inside the toilet body 20, the electromagnetic valve 24 functioning as an on-off valve is provided close to the connecting portion 26. It is done. The substantially H shape of the discharge portion 22 communicating with the reservoir portion 18 may be a P type, a U type, a bowl shape or the like in addition to the illustrated shape. All of these shapes have similar effects.

[0033] The solenoid valve 24 is controlled to open only when the trapped water (water containing dirt) in the reservoir 18 is discharged out of the toilet bowl, and is closed when the toilet is not in use. This is to prevent water leakage. The solenoid valve 24 has a function to prevent leakage of compressed air when the inside of the reservoir portion 18 is pressurized (about 2 atmospheric pressure) using an air conditioner (which will be described later) which constitutes pumping means, in addition to water leakage prevention. There is also.

In the vicinity of the upper portion of the toilet body 20, a flush water supply port 28 is provided on the wall surface 18a on the discharge unit side. A connecting pipe 30 is disposed between the connecting portion 34 provided on the main body rear portion 20 b and the water supply port 28. A branch pipe is used for the connection pipe 30, and a solenoid valve 32 for controlling the cleaning water is attached to the feed pipe 28 at the water supply port 28, and the connection pipe 30 is used. This is to allow the solenoid valve 32 to control the water supply from the water supply hose 12 connected to the connection portion 34.

A washing hose (washing pipe) 240 is also connected to the branched connecting pipe 30 via a solenoid valve 33. The tip of the cleaning hose 240 is provided to project above the surface of the trap water of the reservoir 18. As described later, the inside of the reservoir portion 18 and the back surface of the lid body 212 are cleaned by water injection (actually injection) by the cleaning hose 240.

A rubber-like water leakage prevention pipe 29 is interposed between the water supply port 28 and the wall surface 18a, and the water leakage prevention pipe 242 is also interposed in the reservoir 18 through which the cleaning hose 240 penetrates. To prevent water leakage to the At the bottom of the reservoir 18, crushing means 40 for excrement and the like is provided. The dusting means 40 is for breaking up dirt (excrement etc.) and toilet paper (hereinafter collectively referred to as dirt) accumulated in the reservoir section 18, and the pulverized stream is mixed with the trap water and discharged. .

The pulverizing means 40 can be composed of a motor (electromagnetic motor) 42 and a pulverizing blade 44, and in FIG. 1, only the pulverizing blade 44 is attached so as to face the inside of the reservoir portion 18 in the meantime. Therefore, the motor 42 is disposed on the bottom outer wall 19 side of the reservoir 18 and is fixedly attached to the toilet body 20 by a support 46 such as a bolt or a nut. The rotation shaft of the motor 42 is in watertight engagement with the bottom of the reservoir 18. The motor 42 may be fixed to the bottom plate 20 c of the toilet body 20, which is not located on the bottom outer wall side of the reservoir 18.

Inside the bottom plate 20c, a control unit 50 configured of a CPU or the like is disposed. Control is performed at a predetermined timing for a predetermined time by the driving force of each of the discharge solenoid valve 24, the feed water solenoid valves 32 and 33, the motor 42 and the like and the control unit 50 described above. A power switch 52 for the control unit 50 is provided on the back surface 20b of the main body, and is an upper surface of the main body, and an open / close switch 55 (described later) is provided on the lower surface of the toilet lid 23.

The portable toilet device 10 further has the following structure. As shown in FIG. 1, the crushed portion for feeding predetermined compressed air to the reservoir 18 at a predetermined position below the water supply port 28 at the upper part of the reservoir 18 in the toilet main body 20. A material pumping means 200 is provided. A diameter-reduced portion 230 is provided on the upper side of the reservoir portion 18 and slightly above the mounting position of the pumping means 200. Then, an open / close lid mechanism 210 is provided on the lower surface of the reduced diameter portion 230 so as to close the reduced diameter portion 230 and seal the reservoir portion 18.

The pressure feeding means 200 can be constituted by an air compressor, and the feed pipe 204 of the air compressor 200 is led out to the reservoir 18 side through the attachment means 206. The attachment means 206 is provided above the water surface of the trap water of the reservoir 18. The air compressor 200 is fixed to a mounting plate 202 provided in the rear space 20 a of the toilet body 20.

The same action can be expected even with a mechanism that takes in compressed air from the outside of a portable type portable toilet device body rather than having the air compressor 200 in the toilet body 20.

The reduced diameter portion 230 is configured as an annular flange portion, and protrudes toward the inner surface of the reservoir portion 18 by a predetermined length so as to face a direction. The above-described feed pipe 204 is the trap water of the reservoir 18 and the diameter-reduced portion 230 It is located between

As is apparent from FIG. 1, the reduced diameter portion 230 is provided such that the whole thereof is slightly inclined toward the discharge portion 22. On the lower surface side of the reduced diameter portion 230, an open / close lid mechanism 210 capable of closing the reduced diameter portion 230 is provided. As the open / close lid mechanism 210, a rotary type and a slide type can be considered. The example of FIG. 1 is pivotable.

In this example, since it is a rotating type, it has a lid main body 212 that constitutes the open / close lid mechanism 210.

One end of the lid main body 212, in the example shown, the right end is a pivoting shaft 214, and the pivoting shaft 214 pivots relative to the toilet body 20 so that the pivoting shaft 214 is positioned on the lower surface 232 of the reduced diameter portion 230 It is freely supported. The bearing portion is pivotally supported on the toilet body 20 in a watertight manner.

The lid main body 212 is biased so that its circumferential surface abuts on the lower surface edge 234 of the reduced diameter portion 230. The lid main body 212 has a shape along the lower surface edge 234, and usually the wall surface of the pivot shaft 214 and the lower surface portion 232 so that the inside of the reservoir 18 can be sealed by coming into contact with the lower surface edge 234. A spring 216 for urging is wound between the two.

As described above, since the reduced diameter portion 230 is provided to be slightly inclined toward the discharge portion 22 side, the lid main body 212 itself constituting the open / close lid mechanism 210 is also inclined to the discharge portion 22 side and attached. Be If the lid main body 212 is inclined and attached in this manner, excrement that has fallen on the upper surface of the lid main body 212 can be dropped into the reservoir portion 18 (see FIG. 2).

The end of the cleaning hose 240 is attached to the inside of the reservoir 18 so that the cleaning water can be jetted to both the back surface of the lid body 212 and part of the circumferential surface of the reservoir 18. Be In this example, as shown in FIG. 1, the lid main body 212 is attached and fixed in a watertight manner in the vicinity of the pivot shaft portion 214 and at the lower side thereof.

The water supply hose 12 and the discharge hose 14 are connected to the toilet body 20 configured as described above, and they are led to the existing toilet 3.

FIG. 3 shows an outline of the existing toilet 3. Fig. 3 exemplifies the existing toilet 4 equipped with a warm water washing toilet seat 80. In this case, a branch pipe 84 is connected to a water pipe (water pipe) 82, and a first branch port 86 is provided on the water pipe 82 side of the branch pipe 84, and a hose for hot water washing toilet seat 8 7 Are linked. A second branch 88 is provided near the end of the first branch 86, and a hose 89 for washing water is connected thereto. In this example, the branch pipe 84 having such a branch configuration is used, and a check valve 90 is provided between the first and second branch ports 86 and 88, and the branch pipe 84 is used. A connection 92 to the water supply hose 12 is provided at the end of the A connecting portion 60A provided at the tip of the water supply hose 12 is connected to the connecting portion 92.

Thus, flush water can be supplied to the portable portable toilet device 10 by providing the new branch pipe 84 and attaching the water supply hose 12 thereto. The check valve 90 is installed between the first and second branch ports 86 and 88 because water from the hose 89 and the water supply hose 12 will reversely flow and be supplied to the hot water washing toilet seat It is to prevent them from mixing up with each other.

At the end of the branch pipe 84, a tank 96 filled with a disinfectant is welded to a connection for the disinfectant. By using the disinfectant, the sanitation of the existing toilet 3 as well as the portable simplified toilet system 10 can be improved. Furthermore, the discharge hose can also be cleaned at the same time. Note that the tank 96 may be provided as needed, as long as it is not necessarily provided.

As described above, if the existing toilet water distribution system is diverted, the portable toilet device 10 can be used for a simple extension work only by attaching the branch pipe 84.

The discharge hose 14 is inserted from between the existing toilet 4 and the toilet seat 118 so that the water control cylinder 150 faces the existing toilet 4. The way of insertion is as shown in FIG.

FIG. 4 shows an example of the water supply hose 12 and FIG. 5 shows an example of the discharge hose 14. Assuming that one end 12a of the water supply hose 12 is an end connected to the upper water pipe side and the other end 12b is an end connected to the portable portable toilet device 10, the one end 12a and the other end 12b respectively. Connecting parts 60A, 60B with a check valve are attached.

A connecting portion 62 A with a check valve is attached to one end 14 a of the hose main body 145 constituting the discharge hose 14, and a water control cylinder 150 is provided at the other end 14 b. One end 14a is an end connected to the portable type portable toilet apparatus 10 side.

Since the water supply hose 12 is used for the flush water supplied to the toilet body 20, a small diameter bule hose or the like can be used. On the other hand, since the discharge hose 14 is a pipe in which a stream of crushed waste and the like flows in the pipe, a bule hose having the same diameter or a slightly larger diameter than the water supply hose 12 can be used. This is a hardened filth The purpose is to handle the stream mixed with washing water. FIG. 5 shows the case where the discharge hose 14 having a diameter larger than that of the water supply hose 12 is used.

[0059] If different diameter hoses are used for the water supply hose 12 and the discharge hose 14, the water supply hose 12 may be used as a discharge hose or the discharge hose 14 may be mistaken for a water supply hose because the thickness is different. It is possible to reliably prevent elementary misconnection work, such as connection.

For example, as shown in FIG. 6, a connecting portion 60 (62) having a check valve is provided with a valve operating chamber 64 having a rectangular cross-sectional shape in the hollow inside of the main body 63. A pressure valve 66 for the valve is provided, and the valve is opened by the water pressure acting in the direction of the arrow a. This prevents backflow from both the portable toilet device and the water supply pipe.

On the other hand, in the other connecting portion 60 B, when the connecting portion 60 B is connected to the portable type portable toilet device 10 side, the convex portion (see FIG. (Not shown) is provided on the portable type portable toilet device side so that when the connection portion 60 is connected, the internal valve is opened and brought into communication, and when the connection is released, the internal valve is closed and the inside of the hose is closed. Liquid is leaked to the outside, so that it is configured.

The water control cylinder portion 150 attached to the discharge hose 14 is mounted over the open end edge 4 a (see FIG. 10) of the existing toilet 4 so as to be located inside the existing toilet 4. At that time, a hose clamp 120 is used to fix the discharge hose 14, and this is attached and fixed to the open end 4 a of the existing toilet 4.

FIG. 7 shows an example of this hose clamp 120. The hose clamp 120 is made of resin or the like, and the hose clamp body 121 has a cross-sectional shape of "ヮ" and is shaped along the opening edge 4a. The left end portion 121a of the main body 121 functions as a restraining piece for restraining the outer end edge side of the opening end edge 4a. Similarly, the right end 121b functions as a restraining piece for restraining the inner end edge of the open end edge 4a. A first hose restraining portion 123 is provided on the top surface of the main body 121. The first hose presser 123 is in the shape of a "H", and its inner diameter is slightly larger than the discharge hose 14.

The right end 121b side is approximately twice as long as the left end 121a, and the tip is shaped so as to be slightly bent outward. Then, at the end portion side, a second hose restraining portion 125 directed outward is integrally molded with the main body 121, and the reed is formed. Second hose retainer 12 5 is also in the shape of a "H", and its inner diameter is slightly larger than the discharge hose 14.

FIG. 8 shows the hose clamp 120 mounted on the open end 4 a side. FIG. 9 particularly shows the case where the hose clamp 120 is attached to the back side of the pedestal 118 a provided at the bottom of the toilet seat 118.

FIG. 10 shows a cross section of the installed state of the hose clamp 120. The discharge hose 14 according to this invention is used as the discharge hose 14. The discharge hose 14 is composed of the hose body 145 and the water control cylinder 150 attached and fixed to the tip of the hose body 145. The discharge hose 14 is drawn into the existing toilet 4 while its circumferential surface is held down by the first and second hose holding portions 123, 125.

When the toilet seat 118 is lowered, the outer diameter of the discharge hose 14, the height of the first hose holding portion 123, and the height of the first hose holding portion 123 so that the discharge hose 14 is contained in the space with the bottom of the toilet seat 118 generated by the pedestal 118a. The height of the pedestal 118a, etc. are selected, and they are to be selected.

A control cylinder portion 150 attached to the tip of the discharge hose 14 drawn into the existing toilet 4 is attached and fixed near the neck 4 b of the existing toilet 4. For example, it is attached to the narrow portion 4b by a rubber-like adsorber 148 in a trumpet shape. By using the adsorbent 148, the water control cylinder 150 can be removed from the constricted part 4b, so cleaning of the water control cylinder 150 becomes easy.

FIG. 11 is a cross-sectional view of an essential part showing an example of the water control cylinder 150. The water control cylinder portion 150 is composed of a connection portion 151 to the hose main body 145 and a cylinder portion main body 152 provided in series with the connection portion 151. A cylindrical body is used for the cylinder main body 152, and a plurality of water control pieces 154 are provided therein.

The water control pieces 154 are arranged in a zigzag shape, and in the case of FIG. 11, have a substantially semicircular right water control piece 154a and a substantially semicircular left water control piece 154b. These are arranged in a plurality of zigzags with a predetermined interval maintained. The water control pieces 154 are provided substantially orthogonal to the flow direction so as to protrude in the flow direction of the flow.

The water control piece 154 is a braking piece for causing the fluid force discharged from the discharge hose 14 to flow down by a constant amount while suppressing the flow velocity. Between the number, size and arrangement of water control pieces 154 The interval is optional, but if the number is too large or the arrangement interval is too narrow, the flow down may slow down or the flow down time may be long. It is necessary to select according to the inner diameter etc. In the example of FIG. 11, a total of three water control pieces 154 are used to constitute the water control cylinder portion 150, and even with this, a sufficient water control effect (discharge amount restriction and deceleration effect) can be obtained.

As described above, since the water discharge speed (flow velocity) at the tip opening of the water control cylinder portion 150 can be reduced by the water control pieces 154, the internal pressure can be dispersed. Even if the pump is pumped, the fluid S can be discharged by a substantially constant amount while decelerating. Since the internal pressure can be reduced, the tip end portion of the discharge hose 14, that is, the water control cylinder portion 150 does not go out of control by the reaction force of the discharge pressure of the fluid, and the scattering of the fluid can be avoided.

Therefore, if the discharge hose 14 with the water control tube portion 150 is applied between the portable simple toilet device 10 of the toilet system and the existing toilet 4, even if the waste is pumped, the entire inside of the existing toilet is obtained. It is hygienic because it does not scatter the filth.

[0074] FIG. 12 and the following are other examples of the water control cylinder portion 150, and FIG. 12 uses the same water control piece 154 as FIG. If you are inclined to This makes the passage of the stream smoother.

The example of FIG. 13 is the case where the cylindrical portion main body 152 is formed into a reverse funnel shape (trumpet shape) which is a cylindrical body, and the other configuration is the same as that of FIG. By opening it downstream, the reaction force of the flow can be suppressed, so that the runaway associated with the flow of the flow can be reduced.

FIG. 14 shows a modification of FIG. 13, in which the inclination of the water control piece 154 is made the same as in the case of FIG. The effect is the same as in FIG.

[0077] FIG. 15 shows the case where a diverting piece 156 is provided on the top of the water control piece 154 in addition to the water control piece 154. Therefore, a square body is used for the tubular portion main body 152, and the diverting piece 156 is formed in an arc shape as shown in FIG. 16, and the convex portion thereof is provided so as to face the upstream side.

Since the fluid collides with the diverted piece 156, the flow velocity is reduced, and the diverted flow to the left and right uniformly flows down the inside of the tubular portion main body 152, thereby further enhancing the water control effect. That ability S can.

FIG. 17 shows an example of a control system of the portable toilet device 10. As shown in FIG. Power switch 52 mentioned above In addition, an open / close switch 55 and a drain switch 244 are provided, and the on / off signal thereof is supplied to the control unit 50.

The power switch 52 is turned on when installing the portable toilet device 10

. On the other hand, the open / close switch 55 is a switch that is turned on and off in association with the opening and closing of the toilet lid 23 for closing the upper portion of the toilet seat 21. Therefore, as shown in FIG.

An open / close switch 55 (such as an open / close detection sensor switch) is attached to the lower surface of the toilet lid 23 so as to face 3. The drainage switch 244 can be provided, for example, behind the toilet lid 23

. It is because the frequency of use is low.

The solenoid valve for exhaustion 2 described above according to the control signal from the control unit 50 configured by the CPU

4, Solenoid valve for water supply 32, Solenoid valve for cleaning 33, Motor for crushing 42 and Air compressor 2

Each driving state of 00 is controlled.

FIG. 18 shows an example of the control timing. In the case of the portable type portable toilet apparatus 10, it is assumed that the lid main body 212, which is an open / close lid, is closed when the tile is not used.

The portable toilet device 10 is used by opening the toilet lid 23. The opening operation of the toilet lid 23 is detected by the open / close switch 55 (such as an open / close detection sensor switch) (A in FIG. 18). Use it while the toilet lid 23 is open. When the excrement falls on the lid main body 212, the lid main body 212 is opened by its own weight, and the excrement falls into the trap water of the reservoir 18 (see FIG. 2). When the waste drops, the lid body 212 closes automatically. This is because the lid main body 212 is always urged toward the reduced diameter portion 230 side.

[0084] When the bowel movement is finished, the toilet lid 23 is closed (A in Fig. 18). If it is judged that the lid is closed, the excrement is crushed for a period Ta (FIG. 18B). Note that instead of performing the operation of closing the toilet lid 23, a start switch corresponding to the open / close switch 55 may be operated by a manual operation to start the crushing process. Crushing time Ta is selected to be a time sufficient to crush dirt and toilet paper. Usually, the time is set to 20 seconds or less, preferably about 5 to 10 seconds.

When the grinding process is completed, the air compressor 200 is driven to supply compressed air to the inside of the reservoir 18 and pressurize it (E in FIG. 18). Pressure treatment time Tb is in the reservoir 18 It is set at the time when the internal pressure rises to a predetermined value (for example 2 atm). The predetermined value of the internal pressure means a pressure enough to reliably pump and discharge the fluid into the existing toilet 4 via the discharge hose 14. In practice, a time Tb at which the internal pressure becomes a predetermined value is preset, and this time Tb is forced.

When the pressurizing time Tb elapses, the exhaust solenoid valve 24 is driven in a state where the air compressor 200 is driven, that is, in a state where compressed air is supplied to the inside of the reservoir portion 18 (see FIG. 18). D). When the discharge solenoid valve 24 is driven and the discharge port 27 is opened, the trap water (flow) in the reservoir 18 is pumped at once by compressed air and discharged to the discharge hose 14 side. Since the discharge hose 14 is connected to the existing toilet 4, the excrement crushed by the crushing means 40 is discharged to the existing toilet 4 side.

[0087] The pumping period Tc is different depending on the installation length of the discharge hose 14 In order to prevent the fluid from remaining in the discharge hose 14, a relatively long time, for example, 10 to 30 seconds is usually obtained. Set to a degree.

When the pumping period Tc has elapsed, the power to the discharge solenoid valve 24 is released, and the drive of the reservoir compressor 200 is stopped (D, E in FIG. 18). The outlet 27 is now closed. Thereafter, the water supply solenoid valve 32 operates to start water supply into the reservoir 18 (C in FIG. 18). The water supply time Td is set to a water injection time when the trap water in the reservoir 18 becomes a predetermined amount. Here, the predetermined amount refers to the amount of water stored until the water surface of the trap water exceeds the bent portion of the discharge part 22. It will be in a standby state when the water injection to the accumulation part 18 is completed.

In this example, as shown in C of FIG. 18, the solenoid valve 33 for cleaning is also operated in synchronization with the operation of the solenoid valve 32 for water supply. When the solenoid valve 33 operates, water injection into the reservoir 18 through the cleaning hose 240, specifically, injection to the back surface of the lid body 212 and injection to the wall surface of the reservoir 18 is performed. Since the back surface of the lid main body 212 and the wall surface of the reservoir portion 18 are cleaned by the injection of the cleaning water, the inside of the lid main body 212 and the reservoir portion 18 can be always kept clean.

It is not possible to simultaneously feed water into the reservoir 18 and wash the lid main body 212 etc. Before feeding water into the reservoir 18, that is, after the pumping-out process of the fluid is completed, washing is not performed. It is also possible to carry out cleaning treatment and simultaneously pump and discharge the washing water at that time. But After that, the water supply into the reservoir 18 is performed after the solenoid valve 24 is closed.

[0091] When moving or removing the portable simplified toilet apparatus 10, it is preferable to drain the trap water in the reservoir section 18. This drainage process is performed independently of the above-mentioned drainage process. In that case, turn on the drainage switch 244 and operate the air compressor 200 as shown in FIG. 19 (A, C in FIG. 19) _{0 The} inside of the reservoir 18 is pressurized by starting the air compressor 200. (C in Figure 19). When the pressure treatment for the period Tf is completed, the discharge solenoid valve 24 operates to open the discharge port for a predetermined period Tg (FIG. 19B).

Trapped water can be discharged from the interior of the reservoir 18 by this pressurized and pressure-feed. Then, after the driving of the air compressor 200 is stopped, a short time ATf is set to close the discharge solenoid valve 24. In this way, trap water discharge processing (water drain processing) is completed. Here, the period Tf may be set to the time Tb described above, and the period Tg may be set to the time Tc.

It is obvious that various modifications can be made without departing from the spirit of the present invention.
