Description

[Detailed Description of the Invention] a. Industrial Field of the Invention The present invention relates to an auger type ice making machine, and in particular, an ice guide tube that connects an ice discharge port of an ice making section and an ice storage section, and ice in the ice guide tube. The present invention relates to an auger type ice making machine having an ice storage detecting device in which an ice storage detecting plate is arranged at a position facing an outlet.

b. Conventional technology In the conventional auger type ice making machine, an ice storage detecting device is provided under the ice guide cylinder so that the sensitive surface of the ice storage detecting plate faces the pile of ice storage, or the top of the ice guide cylinder is covered. An ice storage detection device was provided, and the ice storage detection plate was opposed to the ice pushed out from the ice discharge port.

That is, in the one shown in FIG. 5, the ice made in the ice making unit 1 is stored in the ice storage 4 through the guide port 3 from the discharge port 2, and the ice in the ice storage 4 increases to detect the ice storage. When the ice storage detection plate 5a reaches the top of the plate 5a, the ice storage detection plate 5a is rotated by the weight of the ice, and the switch is opened to stop the ice making operation.
See Japanese Patent No. 18474. ). Further, in the one shown in FIG. 6, the ice made in the ice making section 1 is stored in the ice storage through the ice guide cylinder 3 from the discharge port 2, and when the ice storage is full, the inside of the ice guide cylinder 3 is stored. When the ice reaches the position of the ice storage detecting plate 5a, the ice pushed out from the discharge port 2 activates the ice storage detecting plate 5a to stop the ice making operation (actual exploitation 61-9896).
See FIG. ).

c. Problems to be Solved by the Invention In a conventional auger-type ice making machine, in particular, in a case where a sensitive surface of an ice storage detecting plate of an ice storage detecting device faces a pile of ice storing ice, the ice storing ice detecting plate is operated. Is melted by heat conduction on the contact surface of the ice storage detection plate, the ice storage detection plate returns and repeats the operating state, and finally the ice storage part in the operating range of the ice storage detection plate becomes hollow, and it becomes impossible to detect ice storage. there were.

In addition, in the case where the ice storage detection plate faces the ice pushed out from the discharge port, such hollowing of the ice storage part does not occur because the pushing force of the ice is large, but it does not occur with both side edges of the ice storage detection plate. There is a problem in that the ice wraps behind the ice storage detection plate through the gaps between both side walls of the ice guide tube, making the rotation of the ice storage detection plate impossible, and the ice storage detection becomes impossible.

Therefore, the present invention has been made in order to solve such a problem, and in the case where the ice storage detecting plate is opposed to the discharge port, the ice pushed out from the discharge port may go around behind the ice storage detecting plate. It is an object of the present invention to provide an auger type ice making machine equipped with a non-ice storage detecting device.

d. Means for Solving the Problems In order to achieve the above object, the present invention provides an ice guide tube that connects an ice discharge port of an ice making section and an ice storage section, and an ice discharge port inside the ice guide tube. In an auger type ice making machine having an ice storage detecting device in which an ice storage detecting plate is disposed at a position, a guide plate for guiding the ice discharged from the ice discharge port to the center of the ice storing detection plate, and the tip of the guide plate It is attached to both side walls of the ice guide cylinder while being brought close to the plate and tilted so that the ice discharged from the discharge port is directed to the center of the ice detecting plate.

e. Action A guide plate for guiding the ice discharged from the ice-making outlet to the center of the ice storage plate, and the tip of the guide plate is close to the ice storage plate. Since it was attached to both side walls of the ice guide cylinder by tilting so as to point toward the center of the ice, the gap between the both sides of the ice storage detection plate and both side walls of the ice guide cylinder was blocked by the guide plate, and the ice discharged from the discharge port was Not only can all of the pressure be directed to the central portion of the ice storage detecting plate, but also the pressure cannot be circulated behind the ice storing detection plate, so that the ice storage detecting plate cannot rotate and the ice storage cannot be detected.

f. Examples Hereinafter, examples of the present invention will be described with reference to the auger type ice making machine shown in the drawings.

 In the drawings, the same reference numerals indicate the same or corresponding parts.

In FIGS. 1 and 2, 2 is an ice discharge port for pushing out ice from an ice making unit (not shown), and 3 is an ice guide tube that connects the discharge port 2 and an ice storage unit, which is an ice storage (not shown). The upper portion of the ice guide tube 3 is composed of the top plate portion 3a and the side walls 3b, 3b, and the lower portion thereof has a substantially cylindrical shape and is connected to the ice storage. Reference numeral 5 denotes an ice storage detecting device, which comprises a fixed support portion 5e fixed to the top plate portion 3a of the ice guide cylinder 3 and having a shaft 5f, and an ice storage detection plate 5a pivotally mounted to the shaft 5f so as to be rotatable. . further,
The ice storage detection plate 5a includes end portions 5c and 5c formed in a V shape and side ends 5
b, 5b and a tip portion 5d corresponding to the proximity switch 6 installed on the top plate portion 3. The guide plates 7a, 7a are plates having a V-shaped cross section, and mounting screws 7c are welded thereto. Further, the guide plates 7a, 7a have their tip ends 7b, 7b as close as possible to the ice storage detecting plate 5a, and have screw holes 3d,
It is fastened with a wing nut through 3d. Information board 7a, 7
The distance A between the tips 7b and 7b of a is set to the side edges 5b and 5b of the ice storage detecting plate 5a.
By making the gap smaller than the interval B, the ice storage plate
Take you to the center of 5a. The lower ends of the guide plates 7a, 7a are
It is preferable that the position is equal to or slightly shorter than the position of the lower end 5c of the ice detecting plate 5a. Furthermore, the ice discharge port 2 and the guide plates 7a, 7
In order to prevent the ice from forming a bridge state with a, it is desirable that the interval between the tips 7b, 7b of the guide plates 7a, 7a be narrower in the upper part and wider in the lower part.

The ice made in the ice making section and discharged from the ice discharge port 2 is stored in the ice storage via the ice guide cylinder 3. Now, when the inside of the ice storage is filled with ice and then accumulated in the ice guide cylinder 3 and the ice reaches the position of the ice storage detection plate 5a, the pushing force of the ice pushed out from the ice discharge port 2 is the ice storage detection plate 5a. The ice storage detecting plate 5a is rotated around the shaft 5f of the fixed support portion 5e, and
When 5d is separated from the proximity switch 6, the ice storage detecting device 5 stops the ice making operation of the auger type ice making machine.

The guide plates 7a, 7a are inclined to both side walls 3b, 3b of the ice guide cylinder 3 so that their tips 7b, 7b are as close as possible to the ice storage detecting plate 5a, and the ice is directed toward the central portion of the ice storage detecting plate 5a. As a result, not only the gap between both side walls 3b, 3b of the ice guide cylinder 3 and both ends 5b, 5b of the ice storage detecting plate 5a disappears, but also the tips 7b, 7b of the guide plates 7a, 7a and the ice storage detecting plate. There is almost no ice that wraps around the rear side of the ice storage detecting plate 5a through the gaps between both side ends 5b and 5b of the 5a, and the ice storing detection plate 5a operates reliably by the force of the pushed out ice. Therefore, an undetectable situation caused by going around behind the ice storage detecting plate 5a does not occur. Since the guide plate 7a has its screw 7c fastened by the wing nut 8 through the hole 3d, it can be removed as necessary and does not interfere with sterilization and washing.

In FIG. 3, a guide plate 7a having a wide downward shape is used in order to make the gap between the ice storage detecting plate 5a and the ice storage detecting plate 5a inclined to ensure the operation.
It is shown that the tip of 7a is aligned with the inclination of the ice storage detecting plate 5a.

The example of FIG. 4 is a guide plate 7a for narrowing the distance between the tips 7b, 7b of both guide plates 7a, 7a toward the upper side. The folds 7d of 7a are inclined.

g. Effect of the Invention According to the present invention, the guide plate for guiding the ice discharged from the discharge port to the center of the ice storage detection plate is discharged from the discharge port while the tip of the guide plate is brought close to the ice storage plate. Since the ice is attached to both side walls of the ice guide cylinder with the ice tilted toward the center of the ice detection plate, there is no possibility that the ice storage detection plate becomes unrotatable due to the ice wrapping behind the ice storage detection plate. . Therefore, the ice storage cannot be detected.
