Description

[Detailed description of the invention] Industrial field of application This invention is designed to prevent flaky ice produced by an ice-making machine (hereinafter referred to as "flake ice") from falling into an ice storage warehouse for accumulation and storage. In an ice storage device capable of storing flake ice in an ice storage by scattering part of the ice flakes by centrifugal force, the falling flakes of ice are uniformly spread in a path communicating between the ice making machine and the ice storage. This invention relates to a structure in which disks are rotatably and rationally arranged.

Prior art Ice is frozen in a layer on the inner wall surface of a cylindrical freezing casing, and this ice layer is scraped off with a peeling blade. The resulting ice flakes are then released and stored in an ice storage compartment defined below. A flake ice making machine configured as described above is suitably used, for example, in the frozen preservation of seafood. Since the present invention relates to an ice storage device for this flake ice, in order to contribute to understanding of the present invention, first, the schematic structure of the flake ice making machine will be explained with reference to FIG. 3.

As shown in FIG. 3, the flake ice making machine 10 is installed at the top of the ice storage 12, and the flake ice produced by the ice making machine 10 falls into the ice storage 12 and is stored therein. That is, a cylindrical freezing casing 14 is installed in the upper part of the ice storage 12, and this casing 14
The lower opening thereof communicates with the ice storage 12 through an opening 12a formed in the ceiling surface of the ice storage 12. An evaporator 16 that communicates with the refrigeration system is tightly wound around the outer periphery of the refrigeration casing 14, and forced cooling of the refrigeration casing 14 is performed by circulating a refrigerant through the tube during ice-making operation. When ice-making water is sprayed onto the inner wall surface of the frozen casing 14 from an ice-making water supply source (not shown), this water immediately freezes on the inner wall surface, forming a layer of thin ice.

The refrigeration casing 14 is covered with a heat insulating box 18, and a motor 20 is disposed upside down on top of the heat insulating box 18. Further, inside the refrigeration casing 14, a rotating shaft 22 whose axis is vertically aligned with the casing is rotatably supported by bearings 24 and 26 arranged above and below, and a motor 2 is attached to the rotating shaft 22.
0 output shaft is connected via a reduction gear 28. Note that in the drawings, reference numeral 29 indicates a support member that supports the lower bearing 26.

A peeling blade 30 that extends horizontally by a dimension slightly smaller than the inner diameter of the frozen casing 14 is fixed to the rotating shaft 22, and a cutting edge 30a of the peeling blade 30 is fixed to the rotating shaft 22.
faces the inner wall of the casing with a narrow gap parallel to it. Therefore, as the motor 20 is driven, the thin ice that has frozen on the inner wall surface of the freezer casing 14 is scraped off by the peeling blade 30, and the ice flakes fall into the ice storage 12 from the opening 12a and are removed. They are deposited one after another. The accumulated and stored flake ice is transported to the outside by a screw conveyor 32 disposed within the ice storage 12, as necessary. The ice storage state is detected by an ice storage detection device 34 provided in the ice storage 12, and the operation of the ice making machine is controlled accordingly.

Problems to be Solved by the Invention As shown in FIG. 3, the flake ice making machine 10 is normally placed at the top of the ice storage 12, approximately in the center. Therefore, the ice flakes produced by the manufacturing machine 10 and released falling from the opening 12a of the ice storage 12 are not stored in the upper space of each side wall, but form a mountain shape with the apex located directly below the opening 12a. It tends to accumulate. Therefore, compared to the designed ice storage capacity, it could not be said that the ice storage capacity was utilized to its fullest extent.

In addition, when the flake ice making machine 10 starts making ice and restarts after stopping ice making, the frozen casing 14
A phenomenon has been observed in which some of the ice-making water supplied to the inner wall of the ice falls onto the accumulated flake ice. At this time, flake ice may refreeze to form ice blocks, or these ice blocks may solidify together (blocking).
There are problems that lead to this. Furthermore, when a large amount of flake ice is deposited, the solidification is also promoted by the accumulation pressure. Moreover, when the flake ice solidifies in this way, the ice is scraped out from the bottom of the flake ice by the ice conveyor 32, resulting in a cavity (arching) around the ice conveyor 32.
There is a serious problem in that ice is formed and subsequent ice removal cannot be carried out smoothly.

The flake ice obtained by scraping with the peeling blade 30 is a mixture of granular ice with a large surface area and powdered ice with a small surface area, and when used, these granular ice and powdered ice are mixed uniformly. The best condition is However, in the conventional structure in which flake ice scraped by the peeling blade 30 is simply dropped, the granular ice is deposited biased toward the side wall, and the powdered ice is deposited biased right below the freezing casing 14. As a result, the flake ice taken out by the screw conveyor 32 is disadvantageously concentrated in granular ice or powdered ice.

Therefore, as disclosed in Japanese Utility Model Publication No. 53-87960, a pipe 4 communicating the ice storage chamber 2 and the ice making device 1 is disclosed.
A configuration is known in which a rotating disk 8 functioning as a horizontal diffusion member is disposed directly below the input port 4a, and the disk 8 is rotated by a motor 5. However, with the device described in this publication, it is extremely difficult to arrange the umbrella-shaped disk concentrically with the rotating shaft of the peeling blade directly under the opening of the flake ice making machine. The reason for this is that the problem is how to install the motor that drives the rotating disk directly below the peeling blade in the flake ice making machine. Therefore, in this publication, by bending the connecting pipe 4 in an inverted L shape,
running away from this problem.

Purpose of the invention This invention was proposed in view of the above-mentioned drawbacks inherent in discharging flake ice produced by a flake ice making machine into an ice storage. To provide a new structure in an ice storage device for dropping and storing flaky ice produced in an ice storage in an ice storage, in which an ice diffusion disk is rotatably disposed in a path communicating between the ice making machine and the ice storage. With the goal.

Means for Solving the Problems In order to overcome the above-mentioned problems and suitably achieve the intended purpose, the present invention provides bearings inside a cylindrical casing around which an evaporator is wound, and above and below a vertical center line. A flake ice making machine that rotatably supports a rotating shaft on these bearings and scrapes off an ice layer formed on the inner wall of the casing into flakes with a peeling blade provided on the rotating shaft; The flake ice making machine is vertically supported at the top of the ice storage box, and the lower opening of the ice making machine is communicated with the inside of the ice storage through an opening opened at the top. A flake ice ice storage device in which a disk for dispersion is allowed to rotate horizontally, and the ice produced by the ice making machine and falling is diffused to the surrounding area by the disk and stored uniformly in the ice storage box. , a motor for rotationally driving the ice dispersion disk,
The upper end of the rotating shaft is fixed to the lower side of the bearing located at the lower part of the cylindrical casing, so that it hangs coaxially with the rotating shaft of the peeling blade, and the ice spreading fixing the disc horizontally at its center, and fixing a bracket to the ice storage at one end,
The present invention is characterized in that the lower end of the motor rotating shaft is fixedly supported by the edge of the bracket.

Embodiments Next, a preferred embodiment of the flake ice storage device according to the present invention will be described below with reference to the accompanying drawings. The ice making machine itself is the same as the flake ice making machine according to the prior art shown in FIG. 3, so a detailed explanation thereof will be omitted.

FIG. 1 shows a longitudinal section of an ice storage device according to a preferred embodiment of the present invention. It is fixed hanging down. This motor 36 is of a type in which a fixed shaft 38 is inserted through and supported by a cylindrical motor main body 36a with its axes aligned, and the main body 36a rotates around the fixed shaft 38 by driving the motor 36. be. Both ends of the fixed shaft 38 in the motor 36 in the axial direction protrude from both ends of the main body 36a in the axial direction by a predetermined length, and the upper end 38a thereof is fixed to the bearing 26. Further, inside the ice storage 12, an L-shaped bracket 40 is located at its horizontal portion 40.
The fixed shaft 38 is fixedly suspended from the ceiling surface in a state where the shaft a extends below the opening 12a, and the lower end 38b of the fixed shaft 38 is vertically fixed to this horizontal portion 40a.

The fixed shaft 38 of the motor 36 is formed hollow, and an electric wire (none of which is shown) led from a power supply source outside the ice storage is connected to a known slip ring or the like disposed inside the motor 36. Electricity is supplied.

As shown in FIG. 2, an umbrella-shaped disk 42 is concentrically arranged and fixed on the main body 36a of the motor 36, and is configured to rotate integrally with the main body 36a. That is, as shown in FIG.
A through hole 42a that allows the insertion of the through hole 42a is bored, and the through hole 42a is inserted into the main body portion 36a inserted into the through hole 42a.
It is fixed via a bracket 44 that projects radially inward from the inner circumferential surface of the. As shown in FIG. 1, the umbrella-shaped disk 42 is formed to have a larger diameter than the inner diameter of the freezing casing 14, and the ice flakes scraped by the rotation of the peeling blade 30 are removed from the umbrella-shaped disk 42. It is set so that ice accumulates on the top surface.

Further, as is clear from FIG. 2, the umbrella-shaped disc 42 is formed with a fan-shaped notch 42b extending in the circumferential direction at a required central angle, and a portion of the ice flakes falling from the opening 12a is It passes through the notch 42b and falls and is stored directly below the opening 12a. The umbrella-shaped disk 42 is preferably made of a material with low frictional resistance, such as synthetic resin, and is configured so that ice pieces accumulated on its upper surface slide smoothly. Furthermore, it is also recommended that the upper surface of the umbrella-shaped disk 42 be coated with a material to which ice pieces are difficult to adhere, such as fluorocarbon resin.

Effects of the Embodiment Next, the effects of the flake ice storage device configured as described above will be explained. Flake ice making machine 10
When the operation starts, the ice layer that has frozen on the inner wall of the refrigeration casing 14 is scraped off in the form of flakes by the peeling blade 30 and falls, as described above, and the ice layer is scraped off in the form of flakes by the peeling blade 30 and falls.
It is discharged into the ice storage 12 via 2a. Here, the scraped ice flakes are once accumulated on the upper surface of the umbrella-shaped disk 42, as shown in FIG. Since this umbrella-shaped disk 42 is rotated at a predetermined speed by the drive of the motor 36, the ice flakes accumulated on the upper surface are scattered outward in the radial direction, that is, toward the side wall of the ice storage 12, due to centrifugal force. In addition, umbrella-shaped disk 4
Since the notch 42b is formed in the opening 1
A portion of the ice flakes falling from 2a falls to the bottom of the ice storage via the notch 42b without accumulating ice on the upper surface of the umbrella-shaped disk 42. Therefore, the ice making machine 10
It is possible to accumulate and store flakes of ice that fall from the inside of the warehouse evenly.

Furthermore, the rotation of the umbrella-shaped disk 42 has the advantage of stirring the air inside the refrigerator, thereby making the temperature inside the refrigerator uniform. Furthermore, by appropriately adjusting the rotational speed of the umbrella-shaped disk 42, it is possible to uniformly deposit flakes of ice in the ice storage 12 according to the internal volume of the ice storage 12, and also to prevent the flakes from being intentionally uneven. It can also be deposited.

As mentioned earlier, when the ice making operation is started in the ice making machine 10, there is a phenomenon in which some of the ice making water flowing down the inner wall surface of the freezer casing 14 scatters and falls into the refrigerator. After the water droplets fall on the upper surface of the umbrella-shaped disk 42, they are scattered and attached to the side walls by centrifugal force. Therefore, water droplets falling from the frozen casing 14 do not fall onto the flaky ice deposited in the ice storage 12, thereby preventing blocking and arching from occurring. Furthermore, by scattering the flake ice, the ice particles and powder ice in the flake ice can be stored in a uniformly mixed state, and the flake ice carried out by the screw conveyor 32 is made up of these particle ice. It can be taken out with a uniform mixture of powdered ice and powdered ice.

Note that by disposing a baffle plate (not shown) in the ice storage 12 and causing the scattered ice flakes to collide with this baffle plate, a large amount of flake ice can be accumulated at a desired position, or conversely, a large amount of flake ice can be deposited at a desired position. A place with a small amount of ice accumulation can be provided.

Effects of the Invention As explained above, according to the flake ice storage device according to the present invention, a diffusion disk that scatters a portion of the flake ice falling into the ice storage is placed in the passage connecting the ice making machine and the ice storage. When installing, the above-mentioned mounting structure is adopted. As a result, when installing the motor that drives the scattering disk, there is no need to detour the communication path between the ice making machine and the ice storage to escape the motor, and the spreading disk and motor can be easily and easily installed. It is something.

Furthermore, since the water droplets dripping from the freezing casing when the ice making machine is started can be scattered on the side wall, it is possible to prevent the water droplets from dripping onto the accumulated flake ice and causing blocking or arching. In addition, granular ice and powdered ice in flake ice can be deposited in a uniformly mixed state.
It also has other beneficial effects.
