DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid replenishing method and a liquid replenishing apparatus suitable for replenishing a soap liquid to a tank.

[0002]

2. Description of the Related Art
While the soap liquid tank is provided under the counter in a concealed state, the operation unit is provided so as to be exposed above the counter, and the operation unit is operated to discharge the soap liquid contained in the tank from the discharge nozzle. Apparatuses for dispensing soap liquids are known.

FIG. 7 shows a specific example. In the figure, reference numeral 200 denotes a tank disposed in a concealed state below the counter 202, reference numeral 204 denotes a push operation unit exposed on the counter 202, and reference numeral 206 denotes a discharge nozzle for discharging a soap solution. In the case of this soap liquid discharging device, when the push operation unit 204 is pushed down once or a plurality of times, the tank 2
The soap solution contained in the inside of the nozzle 00 is discharged from the discharge nozzle 206 to the outside.

In the case of this soap liquid discharging apparatus, the soap liquid inside the tank 200 decreases as it is used and eventually becomes empty. Therefore, it is necessary to replenish the soap liquid inside the tank 200 periodically. . Therefore, this discharge device has a supply port 218 at its upper end, a lid 220 which normally closes the supply port 218 and opens it only at the time of supply, and a soap liquid which reaches the tank 200 continuously to the supply port 218. A supply passage is provided.

In the case of this soap liquid discharging apparatus, when the lid 220 is opened and the soap liquid put in the container 224 is poured into the supply port 218, the soap liquid flows downward through the supply passage, and Go in. However, when the soap solution is replenished in this manner, the soap solution foams at the replenishing port 218, and the foam is disturbed, so that the soap solution smoothly flows into the tank 200 and is difficult to go.
Even when the soap solution falls into the tank 200, the fall causes foaming inside the tank 200 and the like, and there is a problem that the foam overflows to the outside of the supply port 218 and comes out.

Further, the tank 200 is hidden under the counter 202, and the amount of the soap solution inside the tank 200,
That is, since the position of the liquid level cannot be confirmed, it is easy for the soap liquid to overflow too much from the replenishing port 218 because the soap liquid is excessively added, and in addition, the soap liquid inside the container 224 is narrowed. When replenishing the replenishing port 218, the replenishing operation has to be performed carefully and little by little so as not to overflow the outside, which causes a problem that the replenishing operation is time-consuming and troublesome.

The case where the soap liquid is replenished to the tank of the soap liquid discharging apparatus has been described above as an example. However, a similar problem may occur more or less when a predetermined tank is replenished with the liquid.

[0008]

The liquid replenishing method and liquid replenishing apparatus of the present invention have been devised to solve such a problem. Claim 1 relates to a liquid replenishing method, which is a liquid replenishing method for replenishing a liquid inside a tank in a concealed state through a replenishing port. The distal end of each of the liquid injection pipe and the air introduction pipe extended from the supply container in a state communicating with the inside of the supply container is inserted into the tank through the supply port, and the supply container is substantially sealed. Under the condition, the liquid in the replenishing container is discharged into the tank through the liquid discharging pipe according to a height difference between the tank and the liquid in the replenishing container, and the air in the tank is discharged into the replenishing container. To the tank by stopping the introduction of the air into the replenishing container by closing the opening at the end of the air introduction pipe at the liquid level due to the rise in the liquid level in the tank. The exit is automatically stopped.

A second aspect of the present invention relates to a liquid replenishing device.
A liquid replenishing device for replenishing a liquid inside a concealed tank through a replenishing port, wherein (a) a replenishing container for storing a replenishing liquid therein, and (b) an opening on one end side communicates with the inside of the replenishing container. (C) a liquid discharge pipe extending from the supply container in a state where the liquid is supplied, and a leading end portion is inserted into the tank through the supply port to discharge the liquid in the supply container into the tank. One end opening extends from the supply container in a state of communicating with the inside of the supply container, and a tip portion is inserted toward the inside of the tank through the supply port to introduce air in the tank into the supply container. And an introduction pipe.

[0010] In a third aspect of the present invention, in the second aspect, the liquid supply pipe and the air introduction pipe have flexibility.

According to a fourth aspect of the present invention, in the liquid supply device according to any one of the second and third aspects, the air introduction pipe is inserted into the tank through the supply port, and the tip end position of the liquid discharge pipe is changed. It is characterized by being located at the same height or higher than the position.

A fifth aspect of the present invention relates to a liquid replenishing method. In the first aspect, the liquid is a soap liquid, the tank is a tank of a soap liquid, and the tank is installed under a counter in a concealed state. There is a feature.

A sixth aspect of the present invention relates to a liquid replenishing apparatus, wherein the liquid is a soap liquid, the tank is a tank of a soap liquid, and the tank is in a concealed state. It is characterized by being installed below.

[0014]

The liquid replenishing method according to the first aspect of the present invention comprises:
The liquid in the supply container is injected at a height difference under the condition that each end of the liquid supply pipe and the air introduction pipe extending from the supply container is inserted into the supply port and the supply container is substantially sealed. Pour into the concealed tank through the outlet pipe, and at the same time, introduce the air in the tank into the supply container,
According to this method, the liquid in the supply container can be supplied to the tank very smoothly and at a high speed.

For example, when only the liquid discharge pipe is extended from the supply container and the liquid in the supply container is discharged into the tank through the liquid discharge pipe, the negative pressure in the supply container decreases as the liquid decreases. Pressure is generated, and the negative pressure becomes a resistance, so that the liquid in the supply container is not easily discharged into the tank.

However, in the liquid replenishing method of the present invention, since the air in the tank is introduced into the replenishing container through the air introducing pipe, a negative pressure may be generated even if the liquid in the replenishing container decreases. Therefore, the replenishment of the liquid is not hindered by the resistance force due to the negative pressure, and the liquid in the replenishing container can be discharged into the tank extremely smoothly and at a high speed.

When the amount of liquid in the tank increases and its liquid level reaches a predetermined position, that is, when it reaches the tip opening position of the air introduction pipe, the tip opening of the air introduction pipe is at the liquid level. Closed,
Thereafter, no air is introduced into the supply container. Here, the resistance against the outflow of the liquid in the replenishing container increases at a stretch, and the discharge of the liquid in the replenishing container to the tank substantially stops.

That is, according to the liquid replenishing method of the present invention, the liquid in the replenishing container can be replenished to the tank very smoothly and at a high speed, and when the liquid amount in the tank reaches a target amount, the liquid is reliably supplied. Since the replenishment can be automatically stopped, the replenishment of the liquid can be performed in a short time and with good workability.

In this case, the liquid supply is stopped suddenly when the liquid in the supply container is reduced or the liquid level is lowered. Therefore, the liquid supply is stopped visually, that is, only the target amount is stored in the tank. The operator can immediately know that the liquid has been replenished.

Further, according to the liquid replenishing method of the present invention, when the soap liquid is replenished, the air in the tank is absorbed into the replenishing container through the air introducing pipe, so that bubbles may be blown out from the replenishing port. Also, when refilling a tank in a hidden position such as under the counter, the amount of liquid in the tank is not known, so excess liquid is replenished, and the excess liquid overflows from the supply port That can be reliably prevented.

Here, the supply port does not necessarily mean a supply port provided in the tank itself. For example, when a pipe extends in a connected state to the tank and liquid is supplied through the pipe. In this case, the spout in the tube is a supply port.

A second aspect of the present invention provides a liquid replenishing apparatus including a replenishing container, a liquid discharging pipe, and an air introducing pipe. Can be suitably implemented.

The one end opening of the liquid discharge pipe communicates with the lower end or the vicinity of the replenishing container under the liquid replenishment state, and the one end opening of the air introduction pipe communicates with the upper end or the vicinity of the replenishing container. They can be connected to a replenishing container so that they are ready for use. In this way, the liquid in the replenishing container can be smoothly supplied to the tank even when the replenishing container is fully filled with the liquid, and the liquid is smoothly supplied until the replenishing container becomes empty. Replenishment can be performed.

It is desirable that the liquid discharge pipe and the air introduction pipe each have flexibility (claim 3). By doing so, the liquid discharging pipe and the air introducing pipe can be freely bent, whereby the respective tips can be easily inserted into the supply port, and the insertion workability is improved.

Further, in this case, the liquid discharge pipe and the air introduction pipe may each have a flexible tube and a hard insertion tube provided at the tip of the tube. By doing so, it is possible to further improve the workability of inserting the leading end portions of the liquid injection pipe and the air introduction pipe into the supply port.

According to a fourth aspect of the present invention, the distal end position of the air introduction pipe is positioned at the same height or higher than that of the liquid discharge pipe when inserted into the supply port. In this case, the liquid can be replenished smoothly and at high speed until the inside of the tank becomes full.

For example, if the leading end opening of the air introduction tube is located below the leading end opening of the liquid discharging tube, liquid cannot be replenished until the inside of the tank is completely filled. Alternatively, the replenishing speed of the liquid into the tank after the front end opening of the air introduction pipe is closed by the liquid level is significantly reduced. However, according to the fourth aspect, it is possible to smoothly supply the liquid until the inside of the tank is completely filled without such inconvenience.

In the present invention, the liquid discharging pipe and the air introducing pipe can be bound to each other by the binding member at a predetermined position on the distal end side. With this configuration, the liquid discharging pipe and the air introducing pipe can be bound. The pipes are separated from each other, which makes it difficult to insert them into the supply port, and the two pipes can be easily inserted into the supply port with the two pipes aligned.

In the present invention, the binding member can also be used as a stopper that regulates the insertion amount of the liquid injection pipe and the air introduction pipe into the supply port. The liquid discharge pipe and the air introduction pipe can be inserted into the supply port at a constant insertion depth, and the liquid can be reliably supplied to the tank to a target amount.

Here, the binding member can be forcibly moved relative to the liquid discharging pipe and the air introducing pipe, that is, its position can be shifted. If you do this,
By shifting the position of the binding member, it is possible to easily change and adjust the insertion amount of the liquid injection pipe and the air introduction pipe.

The binding member can also serve as a positioning member that defines the axial position of the liquid discharge pipe and the air introduction pipe. In this case, the liquid discharge pipe can be used. And when the tip of the air introduction pipe is inserted into the supply port,
The positional relationship between the tip positions can be reliably set to a predetermined positional relationship.

The liquid discharge pipe and the air introduction pipe can be connected and fixed to a cap of the replenishing container, and in this case, the cap is put on the container body of the replenishing container, so that the cap is automatically put on the container body. Specifically, the liquid supply pipe and the air introduction pipe can be connected to the supply container. Therefore, any container body can be used for the liquid replenishing device in the present invention as long as the container body can close the opening by the cap.

In the present invention, a stand for supporting the replenishing container can be provided. With this configuration, the replenishing container is held at a predetermined height by the stand, that is, the replenishing container is manually held during the liquid replenishing operation. Even if it is not, the liquid in the replenishing container can be held at a position where it flows out into the tank with a height difference. Here, the stand can be provided on the cap. With this configuration, the stand can be automatically provided in the supply container simply by fitting the cap into the container body.

As is apparent from the above description, the present invention is suitably applied to a case where a soap solution is supplied to a soap solution tank installed in a concealed state under a counter (claims 5 and 6). .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described in detail with reference to the drawings. 2 to 4, reference numeral 10 denotes a soap liquid discharging device installed on the counter 12;
The tank 14 provided in a concealed state below, and the counter 1
2 and the soap liquid in the tank 14 is sucked up.
And an extrusion device 18 for discharging from the discharge nozzle 16. Reference numeral 20 denotes a housing of the extruder 18, and reference numeral 22 denotes a pushing operation section. The push operation section 22 has a pushable tubular member 24.

A supply port 26 is provided at the upper end of the cylindrical member 24, and the supply port 26 is opened and closed by a lid 28. The lid 28 is always in a state where the supply port 26 is closed, and the pushing operation force is directly applied to the lid 28 downward. The housing 20 has therein a supply passage through which the soap solution supplied from the supply port 26 flows toward the tank 14, and the supply passage is connected to the tank 14 by a connection pipe 30.

FIG. 1 specifically shows a liquid replenishing device 32 of the present embodiment for replenishing the inside of the tank 14 with a soap liquid. In the figure, reference numeral 34 denotes a supply container in the liquid supply device 32,
It has a container body 36 and a cap 40 which is screwed into the opening 38 to make the inside of the supply container 34 substantially sealed. A stand 42 is provided integrally with the cap 40. The stand 42 supports the supply container 34 at a predetermined height in a state where the supply container 34 is turned upside down from the state shown in FIG.

A liquid discharge pipe 44 and an air introduction pipe 46 extend from the supply container 34. These liquid discharge pipes 44 and air introduction pipes 46 are flexible tubes 50, 5 respectively.
2 and insertion pipes 54 and 56 connected to the distal end thereof, which are harder than the tubes 50 and 52 and are inserted from the supply port 26 toward the tank 14. Here, the insertion tube portions 54 and 56 are connected to the tubes 50 and 52 in a fitted state.

The liquid injection pipe 44 and the air introduction pipe 46
Are bound to each other by a binding member 58 at a predetermined position on the distal end side. As a result, the liquid injection pipe 44 and the air introduction pipe 46 are aligned in a parallel state, thereby preventing each of them from falling apart.

The binding member 58 is sized so that it cannot be inserted into the supply port 26.
Also serves as a stopper that regulates the insertion amount of the liquid injection pipe 44 and the air introduction pipe 46 into the tank 14. That is, by inserting the liquid discharge pipe 44 and the air introduction pipe 46 into the inside through the supply port 26 until the binding member 58 comes into contact with the supply port 26, the insertion depth is automatically regulated to an appropriate depth. Can be.

The position of the binding member 58 can be forcibly shifted along the liquid injection pipe 44 and the air introduction pipe 46. By shifting the position of the binding member 58, the liquid is discharged. The tank 14 of the pipe 44 and the air introduction pipe 46
It is possible to adjust the amount of insertion into the inside.

The binding member 58 also serves as a positioning member for defining the relative positions of the tips of the liquid discharge pipe 44 and the air introduction pipe 46 to predetermined relations. Specifically, by moving one of the liquid injection pipe 44 and the air introduction pipe 46 relative to the binding member 58, the positional relationship between the distal ends of the liquid injection pipe 44 and the air introduction pipe 46 is changed, In addition, this can be held at the changed relation position.

As shown in FIG. 1, the cap 40 is provided with a connection port 62 protruding from the cap 40 so as to communicate with a communication hole 60 penetrating the cap 40 in and out.
The end of the flexible tube 50 of the liquid injection tube 44 is fitted to and connected to 2. That is, one end opening of the liquid discharge pipe 44 communicates with the inside of the cap 40 through the communication hole 60. The cap 40 is turned upside down in FIG. 1 when replenishing the tank 14 with a soap solution. That is, the liquid discharge pipe 44 is in a state of communicating with the lower end portion of the supply container 34 in the state where the soap liquid is supplied.

The cap 40 is also provided with an extension tube 64. The extension tube 64 extends into the container main body 36, and its tip is located immediately near the bottom 66. The cap 40 is provided with a protruding tubular connection port 68 in communication with the extension pipe 64, and the end of the flexible tube 52 of the air introduction pipe 46 is fitted to the connection port 68.
It is connected.

In this embodiment, the air introducing tube 46 includes an insertion tube portion 56, a flexible tube 52, and an extension tube 64. When the soap liquid is supplied to the tank 14, the air introduction pipe 46 has one end opening communicating with the vicinity of the upper end of the supply container 34. Here, an extension tube 64 is provided on the cap 40 so that the extension tube 6
4 constitutes a part of the air introduction pipe 46, but this is merely an example, and the tube 52 is inserted through the cap 40 into the container body 36, and the tip thereof is positioned near the bottom 66. It can also be made to be located at.

Next, a method for replenishing the tank 14 in the soap liquid discharging device 10 with the liquid replenishing device 32 using the liquid replenishing device 32 will be specifically described below. First, as shown in FIG. 2 (I), with the liquid replenishing device 32 with the cap 40 removed from the container main body 36, the soap solution put in the predetermined container 70 is introduced into the container main body 36 through the opening 38. Then, the inside of the container body 36 is filled with a soap solution.

Thereafter, as shown in FIG. 2 (II), the cap 40 integrally provided with the stand 42 is
6 into the opening 38. At this point, the inside of the supply container 34 is substantially closed. Next, as shown in (III), the liquid discharge pipe 44 extending from the supply container 34.
And each end of the air introduction pipe 46 is connected to a soap liquid discharging device 10.
From the supply port 26 toward the tank 14.

In this example, as shown in FIG. 3, the respective tips of the liquid discharge pipe 44 and the air introduction pipe 46 are inserted to the inside of the tank 14, respectively. Position in the middle without inserting,
That is, it is possible in some cases to insert the supply passage halfway through the supply passage from the supply port 26 to the tank 14.

In the operation process shown in FIG.
4 and the leading end of the air introduction pipe 46 are inserted into the tank 14 through the supply port 26, the binding member 58 is connected to the supply port 2.
6 is inserted to the position corresponding to 6 (FIG. 3).
(IV)). By doing so, the insertion amount of the liquid injection pipe 44 and the air introduction pipe 46 into the tank 14 can be made a predetermined appropriate insertion amount.

As shown in FIGS. 1 and 2, in this example, the binding member 5 is arranged such that the distal end of the air introducing pipe 46 is slightly higher than the distal end of the liquid discharging pipe 44.
8, their positions are defined in advance.

When the tips of the liquid discharge pipe 44 and the air introduction pipe 46 are inserted into the tank 14, the supply container 34 is turned upside down as shown in FIG. The supply container 34 is supported.
At this time, the supply container 34 is held at a position higher than the upper surface of the counter 12 by a certain distance. As a result, a large difference in height occurs between the tank 14 below the counter 12 and the replenishing container 34, and the soap liquid in the replenishing container 34 flows into the tank 14 through the liquid discharge pipe 44 vigorously due to the height difference.

At this time, the air in the tank 14 is introduced into the supply container 34 through the air introduction pipe 46, specifically, into the uppermost end portion inside the supply container 34. Therefore, the supply container 34
The soap liquid inside flows out into the tank 14 extremely smoothly and at a high speed without receiving the resistance force due to the negative pressure.

When the amount of the soap solution inside the tank 14 increases with the outflow of the soap solution inside the replenishing container 34, and the level of the soap solution reaches a position at which the end opening of the air introduction pipe 46 is closed,
The introduction of the air inside the tank 14 into the replenishing container 34 is prevented, where a great resistance to the reduction of the soap solution inside the replenishing container 34 is exerted, and at this point substantially the outflow of the soap solution inside the replenishing container 34 Stops (see FIG. 3 (VI)).
The stop of the outflow of the soap solution inside the supply container 34 can be easily visually recognized by observing the drop of the liquid level of the soap solution inside the supply container 34.

When the soap liquid is replenished to the inside of the tank 14 and almost to the full state as described above, then, FIG.
Then, the supply container 34 is turned upside down again, and then the liquid discharge pipe 44 and the air introduction pipe 46 are pulled out from the supply port 26. Here, a series of operations for supplying the tank 14 with the soap solution is completed. After that, by closing the lid 28, the soapy liquid ejection device 10 can be used.

As described above, according to this embodiment, the supply container 34
The soap liquid in the tank can be replenished into the tank 14 extremely smoothly and at a high speed, and when the liquid amount in the tank 14 reaches a target amount, the replenishment can be automatically stopped without fail. The soap solution can be replenished with good efficiency.

Further, according to this embodiment, since the air in the tank 14 is absorbed into the supply container 34 through the air introduction pipe 46, it is possible to prevent bubbles from blowing out from the supply port 26 to the outside. Even if it is hidden under the counter 12 and the amount of liquid in the tank 14 is unknown,
It is also possible to reliably prevent an excessive amount of soap solution from being replenished by mistake and overflowing from the replenishing port 26.

In this embodiment, since the liquid injection pipe 44 and the air introduction pipe 46 have flexible tubes 50 and 52, respectively, the liquid injection pipe 44 and the air introduction pipe 46 can be freely bent. This makes it possible to easily insert the respective tips into the tank 14 and to add the liquid discharge pipe 4
4 and the air introduction pipe 46 have rigid insertion pipes 54, 56 at the tips of the tubes 50, 52, so that the liquid injection pipe 44 and the tip of the air introduction pipe 46 can be inserted into the supply port 26. Can be made easier.

Further, in this embodiment, since the tip of the air introduction pipe 46 is held at a position higher than that of the liquid discharge pipe 44 when the tank 14 is inserted into the tank 14, until the inside of the tank 14 becomes full. The soap solution can be supplied smoothly and at high speed.

For example, if the tip opening of the air introduction pipe 46 is located at a position lower than the tip opening of the liquid discharge pipe 44, the soap liquid may be supplied until the inside of the tank 14 is completely filled. The replenishment rate of the soap solution into the tank 14 after the end opening of the air introduction pipe 46 is closed by the liquid level becomes impossible, or the rate of replenishment of the soap solution becomes extremely low. However, in the case of this example, the tank 1 can be used without causing such inconvenience.
The soap solution can be smoothly replenished until the inside is almost completely filled.

In this embodiment, the liquid discharge pipe 44 and the air introduction pipe 46 are connected and fixed to the cap 40 of the replenishing container 34. Therefore, in this embodiment, it is only necessary to cover the container body 36 of the replenishing container 34 with the cap 40. The liquid discharge pipe 44 and the air introduction pipe 46 can be automatically connected to the supply container 34. Therefore, any container body can be used for the liquid replenishing device 32 of this embodiment as long as the container body 36 can close the opening by the cap 40.

In this embodiment, since the stand 42 for supporting the supply container 34 is provided integrally with the cap 40, the stand 42 is automatically provided on the supply container 34 simply by fitting the cap 40 into the container body 36. Further, the replenishing container 34 is placed at a predetermined height by the stand 42, that is, even when the replenishing container 34 is not held by hand during the liquid replenishing operation, the replenishing container 34 is stored in the tank 1 at a height difference.
4 can be held at the position where it flows out.

FIG. 5 shows another embodiment of the stand 42. As shown, in this example, the stand 72
Are configured separately from the cap 40 and directly support the container body 36. In this example, the stand 7
2 is formed in a substantially cylindrical shape.

The above is an example of the case where the soap liquid inside the replenishing container 34 is supplied to the tank 14 with the replenishing container 34 turned upside down. However, as shown in FIG. In this state, the respective ends of the liquid injection pipe 44 and the air introduction pipe 46 extending from the supply container 34 are inserted into the tank 14 through the supply port 26, and in this state, the soap inside the supply container 34 is It is also possible to pour the liquid into the tank 14 through the liquid discharge pipe 44, and at the same time, to introduce the air in the tank 14 into the supply container 34 through the air introduction pipe 46. However, in this case,
A valve 74 is provided in the liquid discharging pipe 44 and the liquid discharging pipe 4
4 and the air introduction pipe 46 through the supply port 26 to the tank 14.
After insertion into the interior, the valve 74 is opened and the supply container 34 is opened.
Conveniently, the internal soap solution is started to be poured into the tank 14.

The embodiment of the present invention has been described in detail above, but this is merely an example. For example, the present invention can be applied when replenishing a liquid other than the above-mentioned soap liquid to the tank, or when replenishing the tank installed at a place other than under the counter with a soap liquid or other liquid in some cases. The present invention can be configured in a form in which various changes are made without departing from the gist thereof.
