Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a water supply device for a self-service tea dispenser or the like.

BACKGROUND OF THE INVENTION In recent years, tea dispensers such as those shown in Japanese Utility Model Publication No. 57-49932, which store hot water in a tank and supply a predetermined amount of hot water to tea leaves, have become widely used. . FIG. 4 shows a conventional water supply device for an automatic tea dispenser.

1 is a hot water storage tank for storing hot water, and 2 is a water supply port of the tank having an opening on the upper surface of the body.

3 is a straw that is placed on the water supply port 2.

The water supply device for the automatic tea dispenser constructed as above will be explained 6. First, when supplying water to the automatic tea dispenser, the automatic tea dispenser is placed in the water supply port 2 provided on the top surface of the machine body! 3 and supply water from the water supply port 2 using a container such as a kettle or an auxiliary tank.

Problems to be Solved by the Invention However, in the conventional configuration, the water supply port 2 is located on the top surface of the machine body, so when the water supply container is tilted to supply water, the water does not hit the water supply port 2 and water is scattered around. Something happened.

Furthermore, when there is no separation distance from the top, such as when the main body of the machine is stored in a cupboard, it has the disadvantage that water cannot be supplied from the top.

The present invention solves the problems of the prior art, and by making it possible to supply water from the front of the machine using a rotatably supported water supply device, water can be supplied reliably without any obstructions when pouring water. Another object of the present invention is to provide a water supply device that can easily supply water even when the machine body is installed in a state where there is no space above the machine body, such as when the machine body is stored in a cupboard or the like.

Means for Solving the Problems To achieve this object, the water supply device of the present invention includes a hot water storage tank, a cylindrical guide extending from the outer wall of the tank, and a cylindrical guide provided at the circumferential surface of the guide to penetrate the wall surface. a water supply receptacle having an elongated hole and an opening on its upper surface; a cylindrical portion extending downward from the bottom of the water receptacle and disposed so as to be freely inserted into the inner circumferential surface of the guide; and an attachment/detachment lever that tightly fits into the groove of the water supply cylindrical portion from the elongated hole of the guide.

Function: With this configuration, the water supply receiver is rotatably supported using the outer peripheral surface of the cylindrical part and the inner curved surface of the guide as sliding surfaces, so when water is supplied, by rotating the water supply receiver, it can be moved further forward than the front of the machine body. It can be pulled out to ensure that the water supply operation is not disturbed, and after the water supply is finished, it can be rotated and stored above the tank without protruding from the front. In addition, when cleaning, by rotating the attachment/detachment lever, the groove in the cylindrical portion and the attachment/detachment lever are disengaged, and the water supply receiver can be easily removed.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings. In FIG. 1, numeral 4 indicates a tea dispenser. 5 is a tank for storing hot water, and a heater 6 is arranged on the bottom surface. Reference numeral 7 denotes a hot water supply valve that performs hot water supply control, and hot water is supplied through a hot water supply port 8. 9 is a hopper for supplying new tea leaves, 1o is a tea leaf exchanging device, and 11 is a tea strainer for extracting a beverage using hot water injected from the hot water supply port 8. 12 is a water supply device that supplies water to the tank 6;

The water supply device will be explained below using the drawings of FIGS. 2 and 3.

13 is a water supply receiver that receives the injected water and guides it to the tank 6. Reference numeral 14 denotes a cylindrical portion extending downward from the vicinity of the lower end of the water supply receptacle 13, and one continuous groove 16 is provided in the circumferential direction at a suitable location on the outer wall surface of the cylindrical portion 14. 1
Reference numeral 6 denotes a cylindrical guide that extends upward from near the front edge of the upper wall of the tank 6 . Two elongated holes 17 of the same shape are symmetrically arranged in the peripheral wall of the guide 16 at appropriate positions passing through the wall surface along the local direction.
An engagement wall portion 18 is formed between the two elongated holes 17 . 19 is attached to sandwich the outer wall of the guide 16, and has a roughly U-shaped arm 2o with two bent arms 2o that follow the inner bottom surface of the groove 15 provided in the cylindrical portion 14 of the water supply receiver 130. This is a detachable lever made of an elastic member. This attachment/detachment lever 19 is installed so that a part of the arm 20 is fitted into the elongated hole of the guide 16 when the water supply receiver 13 is attached. Further, the water supply receiver 130, which is mounted so as to protrude inward, reaches a position where it can engage with the groove 15 of the cylindrical portion 14, and is pressed against the bottom surface of the groove 16 with elastic force.

The operation of the water supply device, such as an automatic tea dispenser, configured as described above will be explained below.

First, to supply water to the tank 6, the water supply receiver 13, which is housed in the front edge K of the upper surface of the tank 5, is rotated approximately 90' and drawn forward. At this time, the cylindrical portion 14 of the water supply receiver 13 is inserted into the guide 16 of the tank 5 with a predetermined clearance, and is in a freely rotatable state. Also, at this time, since the longitudinal direction of the attachment/detachment lever <-19 and the direction connecting the two engaging walls 1B face the same direction, the arm 20 of the attachment/detachment lever 19
is interposed and engaged with the groove 15 of the cylindrical portion 14 through the elongated hole 17 of the guide 16, and the arm 2 is elastically engaged.
Since it is pressed from both sides, even when the water receptacle 13 is rotated, the eyebrow removal lever 19 does not rotate with the water receptacle 13, and the water receptacle 13 does not come off.

The supplied water passes through the inner surface of the cylindrical portion 14 on the lower surface of the water supply receiver 13 and is injected into the tank 6.

Next, when storing the water supply receiver 13, the water supply receiver 13 is rotated to a position where it does not protrude beyond the front edge of the tank 6, so that the water supply receiver 13 is stored above the tank 6.

On the other hand, when cleaning the water supply receiver 13, the removable lever 19
is rotated approximately 90' until the longitudinal direction of the attachment/detachment lever 19 and the direction connecting the two retaining walls 18 form approximately a right angle. At this time, the arm 2o of the attachment/detachment lever 19, which has been held in place by tightening the elongated hole 17 of the guide 16 and intervening in the groove 16 of the cylindrical portion 14, engages the guide 16 as the attachment/detachment lever 19 rotates. The arm 2o of the removable lever 19 starts to engage with the wall 18, and is gradually elastically pushed apart and rides on the outer wall surface of the engagement wall 18. As the arm 2o of the attachment/detachment lever 19 is pushed wider, the arm 2o, which had been intervening up to the inner bottom surface of the groove 16 of the cylindrical portion 14, starts to break away from the groove 16. When the long direction of the attachment/detachment lever 19 and the direction connecting the two engagement walls 1B are substantially perpendicular to each other, and the arm 19 is pushed out to a state along the engagement wall 18, the arm 1
9 completely leaves the state of intervention in the groove. As a result, the water supply receptacle 13, which has been inserted into the guide 16 via the cylindrical portion 14, becomes freely insertable and removable, and can be removed. Next, when installing, the water supply receiver 130 cylindrical part 14
With the inner surface K of the guide 16 inserted, the removable lever 20
is rotated to a position where the longitudinal direction is perpendicular to the direction connecting the two engaging walls 18. At this time, the tape 19 of the attachment/detachment lever 2o is released from its elastically expanded state and has a restoring force until it reaches a position where the longitudinal direction of the attachment/detachment lever 20 and the direction connecting the two engaging walls 18 are the same. In order to recover, a large force is not required to operate the attachment/detachment lever 2o that accompanies the attachment K of the water supply receiver 13.

As described above, according to this embodiment, the cylindrical portion 14 of the water supply receiver 13 is inserted into the cylindrical guide 16 extending beyond the tank 6, and the cylindrical portion 14 is inserted through one long hole of the guide 16.
The water supply receiver 13 can be easily rotated by providing the removable lever 2o so as to reach the groove 16 and intervene.
In addition, the water supply receiver 13 can be easily attached and detached using the attachment/detachment handle 20 during cleaning or the like. In addition, when supplying water, the water supply receiver 13 can be pulled out further from the front of the machine body, so water supply operations can be performed without any hindrance during the water supply operation, and the K41jt wooden body can be stored in a cupboard etc. Water can be supplied even when installed in a situation where there is no space above.

Effects of the Invention As described above, the present invention provides a hot water storage tank, a cylindrical guide extending from the outer wall of the tank, a long hole penetrating the wall surface on the circumferential surface of the guide, and a water supply having an opening on the top surface. a receiver, a cylindrical part extending downward from the bottom surface of the water supply receiver and disposed so as to be able to be inserted into the inner peripheral surface of the guide, grooves arranged circumferentially at appropriate positions on the outer peripheral surface of the cylindrical part, and the guide.
