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. 2, the ice made in the ice making section 1 is stored in the ice storage 4 through the guide tube 3 from the ice discharge port 2, and the ice in the ice storage 4 increases to store ice. When the ice storage detection plate 5a is stored on the detection 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.

Stored in the ice storage through the ice storage, and when the ice storage is full, it is also stored in the ice guide cylinder 3, and when the ice storage reaches the position of the ice storage detection plate 5a, the ice pushed out from the discharge port 2 is the ice storage detection plate.
5a is operated to stop the ice making operation (see Japanese Utility Model Laid-Open No. 61-98961).

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. Melts on the contact surface of the ice storage detection plate due to heat conduction, 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 (arching), making it impossible to detect ice storage. There was a problem.

Also, in the case where the ice storage detection plate faces the ice pushed out from the ice discharge port, such cavitation (arching) of the ice storage portion does not occur because the ice pushing force is large, but the ice storage detection plate The ice wraps behind the ice storage detection plate through the gap between the two side edges of the ice guide tube and both side walls of the ice guide tube, and the ice storage detection plate becomes unrotatable, making it impossible to detect ice storage. In order to prevent the on / off operation, the ice storage operation is stopped only when the ice storage detection state continues for a certain period of time. There is a problem that the ice that has been moved accumulates behind the ice storage detection plate and affects the movement of the ice storage detection plate.

The present invention has been made in order to solve such a problem, and an object thereof is to provide an auger type ice making machine having an ice storage detecting device which does not accumulate ice behind the ice storage detecting plate. There is.

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 arranged at a position to be provided, a partition plate extending toward an ice storing portion from a position near a lower end of the ice storing detection plate is provided, and a first passage is formed in the ice guide cylinder. And a second passage.

e. Action Since the partition plate extending from the position close to the lower end of the ice storage detecting plate toward the ice storage portion is provided and the inside of the ice guide tube is divided into the first passage and the second passage, before the movement of the ice storage detecting plate, that is, Until the ice storage section is full, the ice pushed out from the ice discharge port is mainly accumulated in the ice storage section through the first passage, and the ice passing through the second passage is slightly on both ends of the ice storage detection plate and the ice. It is just the one that wraps around the back of the ice detection plate through the gap between both side walls of the guide tube. Therefore, the amount of ice accumulated in the first passage is larger than the amount of ice accumulated in the second passage, and the ice storage detecting plate is activated when the amount of ice reaches the lower end of the ice storage detecting plate. . However, even at this time, the second
The amount of ice accumulated in the aisle is extremely small, and it is possible to move the ice storage detection plate and sufficiently receive the ice that has passed,
No ice accumulates behind the ice storage plate.

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 FIG. 1, reference numeral 2 is a discharge port for ice that is pushed out 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 (not shown) which is an ice storage. A top plate portion 3a is formed at a connection portion of the ice guide tube 3 with the ice discharge port 2, and an ice storage detecting device 5 is arranged inside and a proximity switch 6 is arranged outside the top plate portion 3a. . The ice detecting device 5 has a top plate 3a.
A fixed fixing portion 5e having a shaft 5f and an ice storage detecting plate 5a rotatably supported by the shaft 5f, and the ice storage detecting plate 5a is a vertical surface that receives the force of the pushed ice. And a horizontal tip portion 5d facing the proximity switch 6. Note that 5b and 5c are the side edge and the bottom edge of the ice storage detecting plate 5a, respectively.

Reference numeral 7 is a partition plate for partitioning the inside of the ice guide tube 3 into a first passage 3c and a second passage 3d, and an upper end 7a thereof is arranged at a position close to a lower end 5c of the ice storage detecting plate 5a and a lower end 7b thereof. Extends into the ice storage that is almost the ice storage.

The ice made in the ice making section is pushed out from the discharge port 2, passed through the first passage 3c of the ice guide cylinder 3 and sent to the ice storage to be stored. Now, when the ice storage is filled with ice and then accumulated in the first passage 3c of the ice guide cylinder 3 and reaches the position of the ice storage detecting plate 5a, the pushing force of the ice pushed out from the ice discharge port 2 is increased. The ice storage detecting plate 5a acts on the ice storage detecting plate 5a to rotate around the shaft 5f of the fixed support portion 5e, and the tip 5d thereof is separated from the proximity switch 6, and after this separated state continues for a certain period of time. (To prevent the on / off operation of the ice making operation due to the chattering of the ice storage detecting device 5), the ice making operation is stopped.

Even when ice is accumulated in the first passage 3c, the second passage 3d of the ice guide cylinder 3 accumulates other than ice that enters through the gaps between the both ends 5b, 5b of the ice storage detection plate and the ice guide cylinder 3. However, when a full amount of ice is accumulated in the first passage 3c and the ice storage detecting plate 5a rotates around the axis 5f, the ice pushed out from the ice discharge port 2 reaches the second passage 3d. Is the second
It will be accumulated in the passage 3d. However, the time during which the ice is accumulated in the second passage 3d is the delay time for preventing the on / off operation of the ice making operation due to the chattering of the ice storage detecting device 5, that is, the position 5a ′ of the ice storage detecting plate 5a. It is a fixed time from the rotation of the to the stop of the ice making operation. Therefore, if the position of the partition plate 7 is designed so that the volume of the second passage 3d becomes appropriate in relation to this fixed time,
Ice will not overflow into the passage 3d and the rotation of the ice storage detecting plate 5a will not be hindered.

In this example, the lower end 7b of the partition plate 7 extends below the lower end 3b of the ice guide cylinder 3, but even if the lower end 7b of the partition plate 7 reaches the center of the ice guide cylinder 3, the ice guide When the volume of the cylinder 3 is large, the same action and effect can be obtained.

g. Effect of the Invention According to the present invention, the partition plate extending from the position close to the lower end of the ice storage detecting plate toward the ice storage part is provided, and the inside of the ice guide cylinder is divided into the first passage and the second passage. Even when ice is accumulated in the first passage to operate the ice storage detecting plate, almost no ice is accumulated in the second passage, and the ice pushed out from the ice discharge port while the ice storage detecting plate is operating is in the second passage. Can be stored in. Therefore, ice does not accumulate behind the ice storage detecting plate (in the rotating direction), and the detection device does not become undetectable because the ice storing detection plate cannot rotate.
