Description

TECHNICAL FIELD The present invention relates to a structure of an ice carry-out door device of an ice making machine, which is intended to be used, for example, an auger type ice making machine, which is used by being incorporated in a cup type beverage vending machine.

[Conventional technology]

As is well known, the above-mentioned auger type ice maker comprises an ice making section and an assembly of an ice stocker that constantly stores the ice made by the ice making section, and carries out the ice carry-out port of the ice stocker. A door device for a door is provided, and the door is opened for a predetermined time in response to a sales instruction, and the ice particles stored in the stocker are carried out toward the ice shooter by an agitator operation inside the machine. Further, in this case, the door opening / closing mechanism is generally of a type in which the door is opened / closed by a solenoid operation via a link mechanism.

On the other hand, when such an ice making machine is used by incorporating it into a cup-type beverage vending machine, it is necessary to sanitize the inside of the ice making machine periodically for sanitary control of the vending machine. In this case, the sanitation method uses the water supply system inside the machine that is connected to the ice making machine, and circulates the pooled sanitation liquid injected into the ice stocker to the water reservoir in the system. The method of cleaning and sterilizing the inside of the ice making machine is widely adopted.

[Problems to be Solved by the Invention]

By the way, the structure of the conventional ice maker has the following problems when performing the above-mentioned sanitation work. That is, in the conventional ice making machine, the ice carry-out door simply has a function of preventing the escape of the ice stored in the stocker, and positively prevents the liquid from leaking when the sanitation liquid is pooled. No special consideration is given to the sealing function to prevent it from happening. For this reason, when performing sanitation of an ice maker in the state of use that has been installed in a vending machine in the past, take measures to insert a seal part prepared as a separate part into the ice carry-out port and perform a liquid-tight seal. However, it is troublesome to attach the seal parts to the ice carry-out port each time the sanitation is performed, which makes the sanitation work troublesome and reduces serviceability for maintenance.

The present invention has been made in view of the above points, and by improving the conventional structure, it is possible to securely liquid-tightly seal the ice carrying port of the ice stocker by the door device itself without installing special sealing parts each time during sanitation. It is an object of the present invention to provide an ice unloading door device for an ice making machine, which is configured to facilitate the sanitation work.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, according to the present invention, an ice carry-out door, which is a flapper type door arranged opposite to the ice carry-out port of the ice stocker, is solenoid-connected through a link mechanism, and the door is controlled by energizing the solenoid. In an ice unloading door device of an ice maker, which is configured to be opened and closed, a seal member is provided on the inner surface side of the door to tightly adhere to the peripheral wall surface of the ice unloading port to seal the ice unloading port in a liquid-tight manner, and the door is closed. In this state, a door closing lock mechanism for forcibly pressing and urging the sealing member together with the door so that the sealing member is brought into close contact with the ice carry-out port of the ice stocker is operated.

[Action]

The sealing member mounted on the inner surface side of the door is pressed and urged by the closing lock mechanism of the door in the closed state to be brought into close contact with the ice carrying port of the ice stocker together with the door. Therefore, it is possible to securely liquid-tightly seal the ice carry-out port of the ice stocker and prevent leakage of the sanitation liquid pooled in the stocker by only operating the closing lock mechanism of the door during sanitation of the ice maker. .

〔Example〕

1 to 5 show the construction and operation of an ice carry-out door device of an ice making machine according to an embodiment of the present invention. First, the structure of the entire apparatus will be described. In the figure, 1 is an ice stocker of an ice making machine, 2 is a heat insulating material for covering the outer circumference of the stocker, 3 is an ice carry-out port opened in the ice stocker, and 4 is continuous with the ice carry-out port. It is an ice shooter and the ice stocker 1
On the other hand, an ice unloading door device 5 is installed opposite to the ice unloading port 3. This ice unloading door device 5 is a swinging open / close type door 6 which is a flapper type door arranged facing the ice unloading outlet 3 and outside thereof, and a solenoid 7 for opening / closing the door.
And a link mechanism 8 including links 8a to 8c for interconnecting the armature 7a of the solenoit and the door 5 as basic components, and these components are mounted on a base 9 for assembly. In the figure, 6a is a fixed support shaft of the door 6, 8d is a fixed support shaft of the link 8b, and 10 and 11 are the fixed support shafts 6a and 6a, respectively.
It is a door 6 attached to 8d and a solenoid return spring.

On the other hand, the base 9 is fixedly supported at two upper and lower positions via a fixed support shaft 12 and an eccentric cam shaft 13 to a mounting plate 14 installed in the ice stocker 1, and these are used for a door locking and locking mechanism described later. I am configuring. A gasket 15 is mounted on the inner surface of the door 6 as a sealing member that is in close contact with the wall surface of the ice stocker 1 at the peripheral edge of the ice carry-out port and liquid-tightly seals the ice carry-out port 3. As shown in FIGS. 4 and 5, both ends of the eccentric cam shaft 13 are pivotally supported by the mounting plate 14, and the eccentric cam portion 13a at the center of the shaft has a hole 9a in the base 9. And a manual operation lever 16 is attached to the shaft end protruding from the mounting plate 14.

Next, the operation of carrying out the ice having the above-described structure will be described. First, in the normal use state of the ice making machine, the eccentric cam shaft 13 is set to the position shown in FIG. On the other hand, it is fixedly supported at the position shown by the solid line in FIG. In the standby state, as shown in FIG. 1, the control contact 17 inserted in the power supply circuit of the solenoid 7 is off and the door 6 is in the ice stocker 1.
Is held at the closed position so as to cover the ice carry-out port 3 from outside. Further, in this standby state, the links 8b and 8c of the link mechanism 8 are positioned in line on a line perpendicular to the door 6. Therefore, in this standby state, this pressing force F is linked to the pressing force F applied to the door 6 from the inside of the ice stocker 1.
Since the fixed support shaft 8d of the link 8b receives it via 8c, the door 6 does not open carelessly while waiting for sale.

When the sales command is given from the standby state, the control contact 17 inserted in the energizing circuit of the solenoid 7 is turned on, the solenoid 7 is energized, and the armature 7a is sucked. As a result, as shown in FIG. 2, the links 8b and 8c swing in the direction of the arrow via the link 8a, and the door 6 swings counterclockwise about the support shaft 6a to open the door. The ice particles 18 stored in the ice stocker 1 are carried out to the ice shooter 4 through the ice carry-out port 3. Here, when the control contact 17 is turned off again after a predetermined door opening time has passed, the solenoid 7 is de-energized, and the link mechanism 8 and the door 6 are brought to the position shown in FIG. 1 by the spring bias of the return springs 10 and 11. Return Return to the closed position.

Next, when performing sanitation of the ice making machine, first
In the standby state shown in the figure, the manual operation lever 16 is externally operated to rotate 180 degrees from the solid line position in FIG. 4 to the chain line position. As a result, the eccentric cam shaft 13 also rotates and the direction of the eccentric cam portion 13a is reversed from FIG. 5 (a) to (b),
At the same time, as shown in FIG. 4, the base 9, which is fitted with the eccentric cam portion 13a, swings slightly clockwise from the solid line position to the chain line position about the fixed support shaft 12 as a fulcrum. By this operation, the assembly including the door 6, the solenoid 7, and the link mechanism 8 mounted on the base 9 also moves forward together with the base 9 toward the ice stocker 1, and as a result, the gasket 15 of the door 6 Comes into close contact with the wall surface of the stocker 1 under pressure and is locked in a sealed state in which the ice carry-out port 3 is securely liquid-tightly sealed. Therefore, even when the sanitation liquid is poured into the ice stocker 1 and pooled, the sanitation work can be performed without the liquid leaking out from the ice carry-out port. By returning the operating lever 16 to the position shown by the solid line in FIG. 4 after the sanitation work is completed,
The ice maker returns to normal use again.

〔The invention's effect〕
