Description

[Detailed Description of the Invention] This invention relates to a water dispensing device, particularly a water pumping mechanism for a home-use dispensing device.

Conventionally, the water feeding mechanism of this type of water dispensing dispenser has been made by carving a screw directly on the outer circumferential surface of a rotating shaft that penetrates the lid of the ice container, fixing a handle to the upper end of the rotating shaft, and fixing the handle to the lower end of the rotating shaft. At the same time, a water plate is fixed to the rotating shaft, and a split nut incorporated in the lid body side is forcibly screwed into or separated from the rotating shaft,
When they are screwed together, by turning the handle to rotate the rotating shaft, the rotational force is caused to screw downward by the split nut, and the ice stored in the ice container is fixed to the lower end of the rotating shaft. Generally, the ice plate is pressed, rotated and lowered, and is gradually cut away by a cutting blade facing the bottom of the ice container.

However, when cutting ice, for example, depending on the size or shape of the ice stored in the water container,
Sometimes, the resistance of the suigami plate of the rotating shaft that engages with the ice is greater than the force of turning the handle and rotating the rotating shaft.

However, with the conventional configuration of the above-mentioned water god feeding mechanism,
Because the split nut is forcibly screwed onto the threaded rotating shaft, the rotational force applied to the handle becomes larger than necessary, creating a large resistance between the rotating shaft and the threaded split nut. acts.

Therefore, if you turn the handle even more forcefully, the screws of split nuts used in home water dispensers are mostly made of nylon, and the screw threads may be crushed or the screws pressing against the ice may break. This was undesirable as it caused problems such as damage to the claws of the plate.

In addition, the structure was complicated and required a large number of parts, which was economically disadvantageous.

Therefore, this invention is an improvement on the conventional water pumping mechanism of the above-mentioned water dispensing dispenser, and the structure of this invention will be explained below according to an embodiment shown in the drawings.

1 to 4, reference numeral 1 denotes a leg body whose lower part is divided into two parts, with a protruding part 1a projecting horizontally and forwardly on the upper part, and a part of the protruding part 1a. It has a mounting portion 1b provided with a cutout.

2 is an arc-shaped guide arm fixed to the inner circumferential surface of the tip of the protruding portion 1a of the leg body 1; 3 is joined along the inner circumferential surface of the guide arm 2;
The ice container 5 is a lid body of the ice container 3, which is fixed by tightening with bolts 4, etc., and the tip portion of an arm plate 6 integrally formed obliquely downward from a part of the back surface of the ice container 3. is rotatably supported around a shaft 7 which is supported on the mounting portion 1b of the protruding portion 1a of the leg 1 as a fulcrum.

8 is a bulge of a predetermined shape formed protrudingly on the upper surface of the lid body 5;
Reference numeral 9 denotes a rotating shaft inserted into the bulging portion 8 of the lid 5, and screw portions 9a are provided at both ends thereof.

Reference numeral 10 denotes a cylindrical screw tube that is loosely fitted around the outer periphery of the rotating shaft 9. A flange 10a having a diameter slightly larger than the diameter of the screw tube 10 is integrally formed at the upper end of the screw tube 10. The crocodile portion 10a is configured to engage with the upper surface of the bulging portion 8 of the lid body 5.

Reference numeral 11 denotes a handle portion screwed onto the threaded portion 9a at the upper end of the rotating shaft 9, and numeral 12 represents a disc-shaped water plate screwed onto the threaded portion 9a at the lower end of the rotating shaft 9.

That is, the lid 5 is configured to be able to be opened and closed in a one-touch manner around the axis 7 of the mounting portion 1b of the leg 1, and when the lid 5 is opened when cutting ice, etc. Ice can be suitably stored in the ice container 3, and the lid 5 can be fitted into the ice container 3 with a single touch, making handling and operation easy and very convenient.

Further, a rotating shaft 9 is inserted through the bulge 8 of the lid body 5 and has a handle portion 11 and a water shield plate 12 screwed to both ends thereof.
rotates about the axis T as the center of rotation as the lid body 5 is opened and closed.

At this time, since the trajectory of the outer periphery of the water plate 12 attached to the tip of the rotating shaft 9 is configured in advance so as not to come into contact with the inner circumferential surface of the ice container 3, for example, the rotating shaft 9 is Even if the lid body 5 is opened and closed in a state where it is extended to the bottom part of the rotary shaft 9
The outer circumferential surface of the ice plate 12 moves in an arc in the vertical direction without coming into contact with the inner circumferential surface of the ice container 3.

Therefore, as described above, the ice storage operation and the opening/closing operation of the lid body 5 can be performed with a single touch, making handling extremely easy.

Reference numeral 13 denotes a knob of a handle protruding and fixed to the tip portion of the handle portion 11, and reference numeral 14 denotes a knob of a handle that is fixed to the tip of the handle portion 11, and 14 is always held in place by the spring force of a spring 16 which is appropriately pressed into a predetermined position on the bottom surface of the handle portion 11 by a set screw 15. 17, pawls arranged radially on the lower surface of the water shield plate 12; 18, reinforcing ribs; 1;
Reference numeral 9 denotes a bracket 20 formed integrally with the bulge 8 of the lid 5 and protruding in the radial direction of the lid 5;
is a nylon retainer nut slidably fitted into the horizontal through hole 19a of the bulge 8, and one end of which is provided with a threaded surface 20a carved with an appropriate thread slope. , is forcibly screwed into the threaded tube 10, and a tapered surface 20b is formed at the other end.

Reference numeral 21 denotes a locking lever in the shape of an abbreviation, which is rotatably supported on the tip of the bracket 19 of the bulging portion 8 with a shaft 22 as a fulcrum. Due to the spring force of the spring 23 provided at the position, the presser nut 20 is brought into contact with the tapered surface 20b of the retainer nut 20 in the bulge 8, and the retainer nut 20 is always pressed toward the screw tube 10 side.
A threaded surface 20a formed at the end is forcibly screwed into the threaded tube 10, and a claw portion 21a formed by bending the other end of the locking lever 21 into an oval shape is attached to the ice container. The lid body 5 is engaged with a protrusion 3a formed protruding along the opening periphery of the ice container 3, and the lid body 5 is fitted onto the ice container 3 in a locked state.

That is, the lid 5 is fitted onto the ice container 3, and the locking lever 2 is
When the handle 11 is turned with the claw 21a of the ice container 3 locked to the protrusion 3a of the ice container 3, the threaded tube 10, which is held free from the rotating shaft 9, will release the flange 10a formed at its upper end. Pressing brake shoe 14 and bulge 8
Due to the presence of the presser nut 20 fitted therein, as the rotary shaft 9 rotates, it rotates together with the retainer nut 20, and the rotary shaft 9 and the threaded tube 10 both spiral downward and descend.

That is, due to the presence of the brake shoe 14 and the holding nut 20, a certain frictional force is generated between the rotating shaft 9 and the threaded tube 10, and the rotational force of the rotating shaft 9 causes the threaded shape of the holding nut 20 to tighten. The screw tube 10 and the rotary shaft 9 are configured to move forward and backward together by means of a screw slope carved on the surface 20a.

Therefore, for example, the water plate 12 fixedly attached to the lower end of the rotating shaft 9
When a large resistance is applied to the screw tube 10, which becomes greater than the resistance of the retainer nut 20 that presses the screw tube 10, the retainer nut 20 moves back, and the screw tube 10, which has been rotating following the rotating shaft 9,
The rotation, that is, the action of descending is suppressed, and the relationship with the rotating shaft 9 becomes free.

Therefore, even when the handle 11 is turned, the screw tube 10 does not rotate, and only the rotating shaft 9 rotates and does not descend.

Therefore, the ice stored in the ice container 3 cannot be scraped together with the water plate 12 of the rotating shaft 9, and the screw tube 10
Since no unreasonable resistance is applied to the screw 3 of the retainer nut 20,
This is convenient because there is no fear that the 0 will be crushed or the claws 17 of the water plate 12 will be damaged.

However, the pushing force by the spring 23 is always acting on the screw tube 10, and the downward screw force set by the spring 23 is acting on the screw tube 10.

Therefore, depending on the amount of ice scraped, the water plate 12 is screwed downward, and when the resistance disappears, it immediately screws downward.

Further, the frictional force between the brake shoe 14 and the screw tube 10 is adjusted by adjusting the set screw 15 which is pressed by the spring force of the spring 16.

Reference numeral 24 denotes a plastic mounting board that is bent into a dogleg shape, and a bolt 25 is attached to the top of a protrusion 24a' formed by bending the tip of the horizontal part 24a into a dogleg shape.
At the same time, the mounting board 24 is always pressed downward by the elastic force of the cushion rubber 26 formed protruding from a predetermined position on the back surface of the ice container 3. It is something that

A cutting blade 27 is tightened and fixed along the surface of the vertical portion 24b of the mounting board 24 with bolts 28, etc.
It is designed to be able to appear and retract from a predetermined position on the bottom of the screen.

Reference numeral 29 indicates a protrusion formed to protrude downward from a portion of the peripheral edge of the back surface of the ice container 3, and reference numeral 30 indicates an adjustment screw screwed through the protrusion 29 in a substantially horizontal state, and is connected to the vertical portion 24b of the mounting board 24. It is placed in contact with the tip of the

Reference numeral 31 indicates a cut ice window bored into the bottom of the ice container 3, and reference numeral 32 indicates a suction cup attached to the bottom of the legs.

That is, when the cutting blade 21 is placed inside the ice container 3 to cut ice, the knob 30 of the adjustment screw 30 is
When you rotate the adjustment screw 30 by holding it, the tip of the adjustment screw 30 will touch the vertical part 24b of the mounting board 24.
The protrusion 243' of the horizontal portion 24a is used as a fulcrum to rotate counterclockwise against the elastic force of the cushion rubber 26, and the cutting blade 27 fastened to the horizontal portion 24a also rotates accordingly. The tip of the ice container 3 can be exposed to the inside of the ice container 3.

Therefore, by rotating the adjusting screw 30 and moving it forward and backward, the roughness of the ice stored in the ice container 3 can be adjusted.
Adjustments can be made with one touch, and the fineness of the shaved ice remains constant, preventing large pieces of shaved ice from coming out.

When fitting the lid 5 into the ice container 3 from the open state, hold down the locking lever 21 which is supported on the bracket 19 of the bulge 8 of the lid 5 by a shaft 22 etc.
When the lid body 5 is fitted in pressure contact with the rotary shaft 9 through the screw tube 10, the rotating shaft 9 is held in a locked state.

Therefore, the handle part 11 and the water plate 12 screwed onto both ends of the rotating shaft become immovable, making it extremely easy to open and close them. The locking position of the rotary shaft 9 can be moved back and forth to an arbitrary length and locked, and the rotary shaft 9 does not move independently when the lid body 5 is opened or closed, which is convenient.

The present invention has the above-mentioned configuration, and the operation thereof will be explained next.

Now, with the lid body 5 open, put ice of an appropriate size into the ice container 3, fit the lid body 5 onto the ice container 3 using the shaft 7 of the mounting part 1b of the leg body 1 as a fulcrum, and secure it. Claw portion 21a of stop lever 21
is locked to the protrusion 3a of the ice container 3 using the shaft 22 of the bracket 19 as a fulcrum, and one end thereof is fitted into the bulge 8 by the spring force of a spring 23 provided at a predetermined position of the lid 5. The holding nut 20 is pressed against the tapered surface 20b, and its threaded surface 20a is screwed into the threaded tube 10.

At this time, the set screw 15 of the handle part 11 screwed into the threaded part 9a at the upper end of the rotating shaft 9 pushes the brake shoe 14 into the flange part 10a of the threaded tube 10 by the spring force of the spring 16.
Since the handle part 11 is brought into pressure contact with an appropriate pressing force, when the knob 13 of the handle part 11 is rotated, the rotating shaft 9 rotates and the rotational force is transmitted to the threaded tube 10 side, and the threaded tube 10 is rotated. It rotates together with the rotating shaft 9.

The threaded tube 10 is connected to the threaded surface 20 of the holding nut 20.
Due to the slope of the screw formed in a, a downward movement occurs as it rotates, and the rotational force of the rotating shaft 9 is divided into a downward pressing force, so that the rotating shaft 9 descends together with the rotating shaft 9.

As the rotary shaft 9 descends, the water plate 12 screwed onto the threaded portion 9a at the lower end is rotated and lowered, and the claw 17 is inserted into the ice stored in the ice container 3. At the same time, the ice in the ice container 3 is pressed down and begins to be rotated, and due to the presence of the cutting blade 27 facing the bottom of the ice container 3, the ice is gradually shaved and placed through the water droplet 31 into a suitable saucer. Let it be carved out.

That is, in the water supply mechanism of the liquid dispenser according to the present invention, due to the presence of the brake shoe 14 and the holding nut 20, a certain amount of friction is created between the rotating shaft 9 and the screw tube 10, which have been kept in a free state until now. A force is generated, and as the rotary shaft 9 rotates, the rotary shaft 9 and the threaded tube 10 are moved forward and backward as one body by the thread slope carved on the threaded surface 20a of the holding nut 20. This is what I did.

Therefore, for example, the water plate 2 fixed to the lower end of the rotating shaft 9
When a large resistance is applied to the screw tube 10, which becomes greater than the resistance of the brake shoe 14 and the holding nut 20 that press the screw tube 10, the screw tube 10, which has been rotating following the rotating shaft 9, starts to rotate, that is, to descend. This effect is suppressed, and the relationship with the rotating shaft 9 is severed.

Therefore, even when the handle portion 11 is turned, the rotating shaft 9 rotates, but the screw tube 10 does not rotate, and only the rotating shaft 9 rotates freely, and the action of descending does not work.

Therefore, the ice stored in the ice container 3 cannot be scraped together with the water plate 12 of the rotating shaft 9, and the screw tube 10
Since no unreasonable resistance is applied to the retainer nut 20, there is no fear that the screw thread of the retainer nut 20 will be crushed or that the pawl 17 of the water shield plate 12 will be damaged.

In addition, the structure is simple, the number of parts is small, and it can be manufactured at low cost, making it economical.

As explained above, in this invention, a presser nut having one side of a tapered surface and the other side of a threaded surface is slidably fitted in the bulge formed protruding from the upper surface of the lid, and the lid is A cylindrical external threaded tube loosely fitted around the outer periphery of a rotating shaft formed by vertically penetrating and holding the bulging part of the holding nut is screwed into the threaded surface of the holding nut, and the lid of the locking lever and the ice container are screwed together. With the locking operation, one end of the tapered locking lever presses the tapered surface of the presser nut, and the handle is screwed onto the upper end of the rotating shaft at a predetermined position via a spring. Since the brake shoe, which can be suppressed and adjusted using a press screw, is brought into pressure contact with the outer circumferential surface of the upper end of the threaded tube, when the handle is turned to rotate the rotating shaft during cutting, the rotational force is applied to the brake shoe and the presser foot. Due to the presence of the nut, the force is transmitted to the threaded tube side and rotates as one with it, and the threaded tube has an action that tends to descend due to the threaded slope of the threaded surface of the retaining nut that is threaded therewith. works, dividing the rotational force of the rotating shaft into a downward pressing force and moving down together with the rotating shaft.

In addition, if a large resistance is applied to the rotating shaft side and becomes greater than the resistance of the brake shoe and holding nut, the movement of the rotating shaft to rotate or descend is blocked, and the relationship between the screw tube and the rotating shaft is in a free state. becomes.

For this reason, even when the handle is turned, the rotating shaft rotates, but the screw tube does not rotate, and only the rotating shaft rotates freely, and the downward movement does not work.

Therefore, the ice stored in the ice container cannot be scraped by turning it around, and the screw tube is not subjected to excessive resistance, which may crush the screws of the retainer nuts or damage the claws of the retainer plate. Fear disappears.

Furthermore, it is economical because the structure is simple, the number of parts is small, and it can be manufactured at low cost.
