Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure of a cleaning liquid supply port provided for supplying a highly viscous cleaning liquid such as liquid soap into a tank.
[0002]
[Prior art]
The cleaning liquid automatic discharge device equipped in the automatic hand washing machine that automatically discharges water and cleaning liquid just by putting out a hand is arranged below the washing machine and the washing liquid discharge nozzle arranged above the washing machine The cleaning liquid tank includes a cleaning liquid tank and a pump for supplying the cleaning liquid stored in the cleaning liquid tank to the cleaning liquid discharge nozzle. In addition, a cleaning liquid supply port for supplying cleaning liquid to the cleaning liquid tank is provided above the cleaning liquid tank, the cleaning liquid supply port and the cleaning liquid tank are communicated with each other through a liquid supply pipe, and the cleaning liquid supply port is for capturing dust and the like. A filter and an opening / closing lid for closing the cleaning liquid supply port when not in use are attached.
[0003]
When it is necessary to replenish the cleaning liquid in the cleaning liquid tank, the opening / closing lid is removed, and the cleaning liquid stored in the cleaning liquid supply container or the like is poured into the cleaning liquid supply port from the cylindrical spout. The poured cleaning liquid passes through the filter and flows into the liquid supply pipe. After flowing down through the liquid supply pipe by its own weight, it is accommodated in the cleaning liquid tank.
[0004]
[Problems to be solved by the invention]
The filter attached to the cleaning liquid replenishing port is important as a means for catching dust and the like. However, since a large resistance is generated when the cleaning liquid passes, it is one of the obstruction factors for the cleaning liquid replenishing operation. That is, when a large amount of cleaning liquid is poured into the cleaning liquid supply port at once, the cleaning liquid that cannot pass through the filter overflows from the replenishment port. The replenishment work takes a long time.
[0005]
The present invention has been made in order to solve such a problem, and it is possible to facilitate and expedite cleaning liquid replenishing work, and to prevent overflow of cleaning liquid during replenishing work. The purpose is to obtain.
[0006]
[Means for Solving the Problems]
The cleaning liquid supply port structure of the present invention is inserted into the cylindrical casing connected to the upper end opening of the liquid supply pipe communicating with the cleaning liquid tank, and the cylindrical casing into which the cleaning liquid supply cylindrical spout can be loosely inserted. And a cylindrical or annular seal that holds the outer periphery of the cylindrical spout and the inner periphery of the receiver in a liquid-tight state when the cylindrical spout is inserted into the receiver. It is provided with a stopper.
[0007]
When the cleaning liquid replenishing cylindrical spout is inserted into the cleaning liquid replenishing port, the cylindrical spout inserted in the cylindrical casing and the receiving tool are held by a cylindrical or annular sealing tool. The cleaning liquid in the cleaning liquid replenishing container can be continuously poured as it is, and it is not necessary to adjust the injection amount frequently. Therefore, the cleaning liquid replenishing operation can be facilitated and speeded up, and the overflow of the cleaning liquid during the replenishing operation can be prevented.
[0008]
The material of the tapered cylindrical receiver is preferably polypropylene (PP) or the like, and the cylindrical or annular sealing member is liquid-tight and has high corrosion resistance to the replenishing cleaning liquid. For example, silicon rubber is suitable. Further, if a filter is provided near the tip of the receiving tool, dust and the like mixed in the cleaning liquid can be captured.
[0009]
In addition, it is more preferable that the shape of the receiving tool is tapered, and the diameter of the tip is smaller than that of the liquid supply pipe communicating with the cleaning liquid tank. By doing so, the amount of cleaning liquid to be replenished can be suppressed rather than the amount of cleaning liquid flowing to the liquid supply pipe, so that the cleaning liquid to be replenished fills the casing before the cleaning liquid tank is full. Further, there is no possibility that the cleaning liquid flows out of the casing through the air vent gap formed between the casing and the receiving tool.
[0010]
Here, it is desirable to provide an annular protrusion on the inner peripheral surface of the sealing tool that can contact the outer periphery of the cylindrical spout of the cleaning liquid supply container. When the cylindrical spout is inserted through the sealing tool, the ring-shaped projection is in line contact so as to surround the outer periphery of the cylindrical spout, so that the liquid tightness is improved and the overflow prevention function of the cleaning liquid is enhanced. Is obtained.
[0011]
Moreover, it is desirable to arrange a sealing member for enhancing liquid tightness between the inner periphery of the cylindrical casing and the outer periphery of the receiving tool. By arranging such a sealing member, when clogging or the like occurs in the middle of the liquid supply pipe, it is possible to prevent the cleaning liquid being replenished from flowing backward in the liquid supply pipe and overflowing around the replenishing port. it can.
[0012]
On the other hand, it is desirable to provide an air vent pipe that communicates with the cleaning liquid tank and is opened in the cylindrical casing. Since the air vent path in the cleaning liquid tank is secured by the air vent pipe, it is possible to increase the cleaning liquid supply speed. Moreover, since this air vent pipe is opened in the cylindrical casing, even if a part of the cleaning liquid filling the cleaning liquid tank may rise up the air vent pipe, the back side of the basin cannot be seen. The cleaning liquid does not overflow to the part, and the cleaning liquid that has passed through the air vent pipe flows out from the air vent clearance formed between the casing and the receiver to a place where it can be seen outside the casing. The worker who is doing it can be confirmed visually. The connection of the air vent pipe to the casing is preferably provided at a position above the receiving tool. By doing so, before overflowing from the air vent pipe, it becomes impossible to replenish from the receiving tool, and the operator can quickly recognize that the cleaning liquid has sufficiently accumulated in the tank.
[0013]
Further, it is desirable to provide a display device around the cylindrical casing for displaying that the cleaning liquid tank is filled with the cleaning liquid. By providing such a display device, it is possible to visually check the end time of replenishment during the replenishment operation, so that insufficient replenishment of the cleaning liquid and overflow can be prevented, and workability is improved. The display device is preferably a light emitting diode that is turned on by a sensing signal from a liquid level sensor that senses the amount of cleaning liquid in the cleaning liquid tank.
[0014]

It is a rear view around a supply port.
[0015]
As shown in FIGS. 1 and 2, the cleaning liquid supply port 1 in the present embodiment is disposed behind the side surface of the automatic hand-washing machine 4. The automatic hand-washing machine 4 includes a water discharge nozzle (not shown) that discharges water when the hand is held out, a cleaning liquid discharge nozzle 2 that discharges the cleaning liquid when the hand is held out, a wash-basin 3 that collects and drains hand-washing water, and a wash-basin 3 and the like are provided.
[0016]
As shown in FIG. 3, in the casing 5, the cleaning liquid tank 6 that stores the cleaning liquid, the liquid level sensor 7 that detects the cleaning liquid level in the cleaning liquid tank 6, and the cleaning liquid in the cleaning liquid tank 6 are supplied to the cleaning liquid discharge nozzle 2. There are disposed a cleaning liquid pump 8, a liquid supply pipe 9 communicating with the cleaning liquid tank 6, an air pump 10 for sending air into the cleaning liquid tank 6, and the like. 1 to 3, members that are not directly related to the function of the cleaning liquid supply port 1 are omitted.
[0017]
As shown in FIG. 4, the cleaning liquid replenishing port 1 has a cylindrical casing 11 connected to the upper end opening of the liquid supply pipe 9 communicating with the cleaning liquid tank 6 and a cylindrical spout 12a of the cleaning liquid replenishing container 12 loosely inserted. A tapered cylindrical receptacle 13 that can be inserted into the cylindrical casing 11, and the outer periphery of the cylindrical spout 12 a and the inner periphery of the receiver 13 when the cylindrical spout 12 a is inserted into the receiver 13. A cylindrical sealing tool 14 that is engaged in a liquid-tight state, an opening / closing lid 15 that covers the cleaning liquid supply port 1, and the like are provided. A filter 16 for capturing dust and the like in the cleaning liquid is provided at the tip of the receiving tool 13.
[0018]
As shown in FIG. 5, when the cylindrical outlet 12 a of the cleaning liquid supply container 12 is inserted into the cleaning liquid supply port 1, the receiving tool 13 and the cylindrical outlet 12 a that are inserted so as to be held and fixed to the cylindrical casing 11. Is held in a liquid-tight state by the cylindrical sealing tool 14. Further, an air vent gap 24 is provided between the outer periphery of the receiving tool 13 and the cylindrical casing 11 for extracting the air from the air vent pipe 17 to the outside. A protrusion (not shown) is formed on the outer periphery of the receiving tool 13 along the direction of insertion into the cylindrical casing 11 and an engaging portion 25 as shown in FIG. 6 is provided. By securing a space between the protruding portion and the cylindrical casing 11, a clearance 24 for removing air is surely formed.
[0019]
On the other hand, since the shape of the receiving device 13 is tapered to suppress the amount of cleaning liquid to be replenished, it overflows even if the cleaning liquid in the cleaning liquid supply container 12 is continuously poured while the cylindrical spout 12a is inserted. This eliminates the need for frequent adjustment of the amount of the cleaning liquid injected. Therefore, the cleaning liquid replenishing operation can be facilitated and speeded up, and the overflow of the cleaning liquid during the replenishing operation can be prevented.
[0020]
Further, since the receiving tool 13 has a tapered shape, the diameter of the tip thereof is smaller than that of the liquid supply pipe 9 communicating with the cleaning liquid tank 6, so that the amount of the cleaning liquid to be replenished is larger than the amount of the cleaning liquid flowing through the liquid supply pipe 9. Before the cleaning liquid in the cleaning liquid tank 6 becomes full, the cleaning liquid to be replenished fills the cylindrical casing 11 and the cleaning liquid is between the cylindrical casing 11 and the receiving device 13. There is no fear of flowing out of the cylindrical casing 11 from the air vent gap 24 formed in the above.
[0021]
In the present embodiment, the material of the receiving device 13 is polypropylene, and the material of the sealing device 14 is silicon rubber, so that excellent liquid-tightness is obtained. However, the material is not limited to these materials. Any material having corrosion resistance, liquid tightness, etc. may be used.
[0022]
Moreover, since the annular protrusion 14a which can contact the outer periphery of the cylindrical spout 12a of the cleaning liquid replenishing container 12 is provided on the inner peripheral surface of the sealing tool 14, the cylindrical spout 12a is placed in the sealing tool 14. When inserted, the annular protrusion 14a makes line contact so as to surround the outer periphery of the cylindrical spout 12a, so that the liquid-tightness is high and an excellent cleaning liquid overflow prevention function is obtained.
[0023]
Further, as shown in FIGS. 6 and 7, since the air vent pipe 17 is provided in the cylindrical casing 11 so as to communicate with the cleaning liquid tank 6, the air vent pipe 17 is used to supply the air inside the cleaning liquid tank 6 during the cleaning liquid supply operation. Air is efficiently discharged, and the cleaning liquid replenishment speed can be increased. Since the air vent pipe 17 is opened in the cylindrical casing 11, a part of the cleaning liquid that has filled the cleaning liquid tank 6 should be removed from the air vent pipe. Even if 17 is raised, the cleaning liquid does not overflow to the back side of the basin 3.
[0024]
Further, as shown in FIG. 6, an indicator lamp 18 is provided on the side of the opening of the cylindrical casing 11 to indicate that the cleaning liquid tank 6 is filled with the cleaning liquid. It is possible to visually check the end time, prevent insufficient supply of the cleaning liquid and overflow, and improve workability. The indicator lamp 18 uses a light emitting diode that is turned on by a detection signal from the liquid level sensor 7 that detects the amount of the cleaning liquid in the cleaning liquid tank 6.
[0025]
Next, with reference to FIG. 8, a cleaning liquid supply port 20 of another embodiment will be described. In addition, in FIG. 8, about the member which exhibits the same function as the washing | cleaning-liquid supply port 1 of previous embodiment, the same code | symbol as FIGS. 1-7 is attached | subjected and description is abbreviate | omitted.
[0026]
The structure and function of the cleaning liquid supply port 20 are the same as those of the cleaning liquid supply port 1 of the previous embodiment, but on the outer periphery near the tip of the tapered cylindrical receptacle 21 inserted in close contact with the cylindrical casing 11. An annular groove 22 is provided, and an O-ring 23 is disposed in the annular groove 22 as a sealing member for enhancing liquid tightness between the cylindrical casing 11 and the outer periphery of the receiving tool 21. By arranging the O-ring 23, when clogging or the like occurs in the middle of the liquid supply pipe 9, it is possible to prevent the cleaning liquid being replenished from flowing backward in the liquid supply pipe 9 and overflowing around the replenishment port 20.
