Description

  The present invention relates to an auger type ice making machine, and more specifically, the ice generated on the ice making surface of a refrigeration casing is peeled off and conveyed by a rotating blade of an auger rotated by a driving means, and the conveyed ice is iced. The present invention relates to an auger type ice making machine that is discharged after being collected by a collecting unit.

  FIG. 18 is a schematic configuration diagram showing an auger type ice making machine with the ice making mechanism section broken. The auger type ice making machine 10 includes an ice making mechanism 12 including a refrigeration casing 13 disposed on an upper portion of a housing 11 and an auger (rotary blade) 14 disposed inside the refrigeration casing 13. Further, the auger type ice making machine 10 is provided with a fixed blade 15 which is disposed at the upper part of the refrigeration casing 13 and constitutes the ice collecting part S, and a driving means 16 such as a geared motor for rotating the auger 14 at a predetermined speed. And a reservoir tank (ice making water tank) 17 connected to the refrigeration casing 13 through a water supply pipe 18. The refrigeration casing 13 includes a cylinder 20 having an inner wall surface as an ice making surface 21 and a cooling pipe 22 spirally wound around the outside of the cylinder 20 as an evaporator of a refrigeration circuit (not shown); And a heat insulating material 23 having a required thickness for covering the cylinder 20 and the cooling pipe 22 from the outside. The auger 14 includes a rotary blade 24 that spirally projects from the outer peripheral surface of the cylindrical main body, and the blade tip surface of the rotary blade 24 faces the ice making surface 21 in a non-contact state.

Such an auger type ice making machine 10 supplies ice making water supplied to the reservoir tank 17 to the inside of the ice making mechanism section 12 (between the freezing casing 13 and the auger 14) via a water supply pipe 18 for freezing. By cooling the cylinder 20 of the refrigeration casing 13 by the circuit, ice is generated on the ice making surface 21 that is the inner wall surface of the cylinder 20. When the driving means 16 is driven to rotate the auger 14 at a constant speed in a predetermined direction, the rotary blade 24 conveys the ice generated on the ice making surface 21 upward while peeling. The ice transported upward is pushed by the continuously transported lower ice and collected by the fixed blade 15, and then discharged through the ice discharge port 25 connected to the top of the ice making mechanism 12. It is pushed out by the chute 26 and transferred to an ice storage chamber (not shown). Such an auger type ice making machine is disclosed in Patent Document 1, for example.

Can be assembled. A through hole 60 is formed in the central portion of the base member 39 to allow the rotation shaft 56 to be inserted. A cylindrical rib 61 is provided on the upper surface of the base member 39 so as to be fitted and connected to the engaging protrusion 100 of the driving means 36. Further, at a portion adjacent to the outer peripheral edge of the base member 39, a first bolt through hole 62 through which the first assembly bolt B1 for assembling the base member 39 and the refrigeration casing 33 is inserted is a required interval on a concentric circle. A plurality (6 in the embodiment) are formed for each. That is, each first bolt through hole 62 is formed so as to be aligned with each first bolt fastening hole 47 formed in the upper end surface of the refrigeration casing 33. A second assembled bolt B2 for fastening the base member 39 to the upper wall portion 90 of the frame 38 is fastened to a portion radially inward from the portion where the first bolt through holes 62 are formed. A plurality of (two in the embodiment) two-bolt fastening holes 63 are formed on the concentric circles at required intervals.

Each fixed blade 64 prevents the ice that has moved substantially vertically upward along the inner wall surface 40 of the refrigeration casing 33 by each rotary blade 50 of the auger 34 from rotating with the rotation of the auger 34, and the inclined guide surface. 64A functions to change the direction of rotation of the auger 34 in the direction of the rotation center (horizontal direction). Note that the fixed blade 64 may extend so as to intersect the radial direction of the circular base member 39. The lower surface of the base member 39 has an inner portion that is recessed as compared with the outer peripheral portion, and a guide surface 67 that is inclined upward from the radially outer side to the inner side is provided between the inner portion and the outer peripheral portion. The guide surface 67 functions as an inclined guide surface, and changes the ice conveyed upward by the rotary blade 50 of the auger 34 to the rotation center side of the auger 34. Note that the fixed blade 64 of the first embodiment protrudes from the guide surface 67. Furthermore, a plurality of protrusions (rotation restricting pieces) extending in a straight line or a curved line from the center of the base member 39 toward the outer peripheral end at a portion facing the upper opening of the auger 34 on the lower surface of the base member 39. 65 protrudes substantially radially. These protrusions 65 come into contact with the ice conveyed between the base member 39 and an ice collecting member 35 described later from above, and the ice collected in the ice collecting member 35 rotates with the rotation of the auger 34. It works to prevent you from doing. Further, a discharge guide surface 66 that bulges downward and radially outward is formed at the central portion of the lower surface of the base member 39. The discharge guide surface 66 is positioned so as to face an ice discharge port 71 (to be described later) of the ice collecting member 35, and the ice moved in the rotation center direction (horizontal direction) along the ice collecting member 35 is rotated by the auger 34. In addition, it functions to prevent the ice from rotating together with the ice and to change the direction downward and to send the ice changed downward to the ice discharge port 71.

  As shown in FIGS. 2 and 5, the auger type ice making machine 30 according to the first embodiment is configured such that an ice collecting member 35 can be detachably attached to the upper opening of the auger 34. The ice collecting part S is formed by the member 35 and the base member 39. That is, when the ice collecting member 35 is attached to the upper opening of the auger 34 (FIGS. 1 and 6), the peeled ice is collected in the ice collecting portion S, thereby increasing the density per unit space. When the generated ice is generated and the ice collecting member 35 is not attached to the upper opening of the auger 34 (FIG. 7), the ice collecting portion S is not formed. Configured to be generated. The ice collecting member 35 is a flange-shaped disk member formed to have substantially the same outer dimensions as the auger 34, and covers the upper opening of the auger 34 when assembled to the auger 34. It is like that. A through-hole 70 is formed in the central portion of the ice collecting member 35 so as to be slidably contacted with the rotary shaft 56 in a loosely fitted state.

It works to push towards. Therefore, as shown in FIG. 5, the ice collecting position P2 which is a part for collecting the ice after peeling is an ice peeling position where the rotary blade 50 of the auger 34 peels the ice generated on the inner wall surface 40 of the refrigeration casing 33. It is set to be closer to the rotation center of the auger 34 than P1 (the position of the cutting edge surface of the rotary blade 50). Thereby, the ice collecting efficiency is improved because the ice collected by the ice collecting member 35 gradually decreases in speed as it moves to the rotation center of the auger 34. Further, since the collected ice moves toward the rotation center of the auger 34, the torque load on the driving means 36 is reduced. In addition, it is possible to adjust the ice collection degree by the ice collecting member 35 by changing the opening size of each ice discharge port 71, 71. For example, the density per unit space is increased as the opening size is reduced. Ice can be produced.

The casing 33 and the auger 34 are immersed. That is, the ice making mechanism portion 32 is configured such that the outer peripheral surface (the outer wall surface 41 of the refrigeration casing 33) is wrapped by the ice making water before being supplied into the ice making mechanism portion 32. In other words, the ice making mechanism 32 of the auger type ice making machine 30 according to the first embodiment is housed in the reservoir tank 37 and immersed in the ice making water so as not to contact the outside air. Therefore, the ice making water is the conventional ice making water shown in FIG. It functions as the heat insulating material 23 in the auger type ice making machine 10 and has a structure that can eliminate the need for a heat insulating material for keeping the ice making mechanism 32 in a low temperature state. Further, since the refrigeration casing 33 cooled by the refrigeration circuit is immersed in the ice making water in the reservoir tank 37, the ice making water before being supplied into the ice making mechanism 32 is brought into contact with the refrigeration casing 33 and appropriately cooled. To get.

  Further, in the auger type ice making machine 30 according to the first embodiment, as shown in FIG. 1, the fixed blade 64 and the ice collecting member 35 for turning the vertically moving ice toward the center are provided to the driving means 36 for rotating the auger 34. It is arranged at a close position. That is, when collecting ice, the auger 34 and the refrigeration casing 33 are required to have a robust structure because the cylindrical body of the auger 34 and the refrigeration casing 33 hardly generate a thrust load for collecting ice. The ice making mechanism 32 is reduced in weight and size. Further, since the ice collecting position P2 by the ice collecting member 35 is close to the rotation center of the auger 34, the torque load on the driving means 36 when collecting ice by the ice collecting member 35 can be reduced.

  Furthermore, the auger type ice making machine 30 according to the first embodiment is arranged in a state where the ice making mechanism portion 32 is accommodated in the reservoir tank 37 as shown in FIG. The structure does not penetrate downward from the bottom wall portion 82. For this reason, there is no leakage of ice making water from the ice making mechanism section 32, and it is not necessary to provide a mechanical seal or the like at the boundary between the ice making mechanism section 32 and the reservoir tank 37. However, it is difficult for water leakage problems to occur. On the other hand, since the reservoir tank 37 is configured as a single member and is not mounted with other components, the reservoir tank 37 can be attached to and detached from the frame 38 only by tightening or loosening the third assembly bolt B3. .

(Operation of Example 1)
Next, the operation of the auger type ice making machine 30 of the first embodiment configured as described above will be described. Here, the operation of the auger type ice making machine 30 that generates the ice with the increased density per unit space equipped with the ice collecting member 35 will be described.

  When a specified amount of ice making water is supplied into the reservoir tank 37 via the water valve 46, the refrigeration casing 33 and the auger 34 in the ice making mechanism portion 32 are stored in the reservoir tank 37 as shown in FIG. The ice making water also flows into the ice making mechanism 32 (between the freezing casing 33 and the auger 34) through the water passage 55. In this state, when the refrigeration circuit (not shown) is operated and the refrigerant is supplied to the cooling pipe 42, the entire refrigeration casing 33 is cooled to cool both the inner wall surface 40 and the outer wall surface 41, which are ice making surfaces. Therefore, while ice is generated on the inner wall surface 40 of the refrigeration casing 33, the ice-making water that is in contact with the outer wall surface 41 (the ice-making water before flowing into the ice-making mechanism 32) is appropriately cooled. The ice-making water before being supplied to the ice-making mechanism 32 is appropriately cooled while being in contact with the refrigeration casing 33. However, as ice making progresses, the ice-making water at room temperature is passed through the water valve 46 in the reservoir tank 37. Since the water is additionally supplied so as to keep the water level constant, little ice is generated on the outer wall surface 41 of the refrigeration casing 33, and in some cases, almost no ice is generated. Here, when the temperature of the supplied ice making water is low, the generation of ice on the outer wall surface 41 of the refrigeration casing 33 is promoted, and there is a possibility that the gradually grown ice may come into contact with the reservoir tank 37. The outer wall surface 41 of 33 may be covered with a small amount of heat insulating material to suppress the formation of ice on the outer wall surface 41. As the heat insulating material in this case, a material having no problem even if it is immersed in ice making water is employed.

  When ice begins to be generated on the inner wall surface 40 of the refrigeration casing 33, the ice generated on the inner wall surface 40 is sequentially peeled off at the ice peeling position P1 by the rotary blades 50 of the auger 34 rotating at a constant speed by the driving means 36. At the same time, it is conveyed vertically upward along the inner wall surface 40. Then, the ice that has reached the upper end of the auger 34 is moved in the horizontal direction by the fixed blades 64 and the guide surfaces 67 provided on the base member 39 and moves toward the center of rotation of the auger 34. It becomes like this. In addition, when the ice conveyed upward by each rotary blade 50 contacts each fixed blade 64, a part of the unfrozen ice-making water contained is separated from the ice.

  Then, the ice that has reached the upper end portion of the auger 34 and whose direction of conveyance has been changed in the horizontal direction by the fixed blades 64 and the guide surfaces 67 is caused by the ice collecting member 35 and the base member 39 as shown in FIG. The auger 34 is moved around the center of the auger 34 by moving inside the formed ice collecting section S and by the ice pressing guide pieces 72 and 72 provided on the upper surface of the ice collecting member 35 and the respective protrusions 65 provided on the lower surface of the base member 39. The upper surface of the ice collecting member 35 is moved toward. Then, the ice moving on the upper surface of the ice collecting member 35 is gradually pressed at the ice collecting position P2 in the process of moving toward the rotation center of the auger 34, and becomes ice with an increased density per unit space. That is, the ice that has moved to the upper surface of the ice collecting member 35 in the ice collecting section S is restricted from rotating in the circumferential direction along with the rotation of the auger 34 by each protrusion 65 and the discharge guide surface 66. Originally, the ice is pressed from the side by the ice pressing guide pieces 72, 72, collected gradually, and becomes ice having an increased density per unit space in the process of moving toward the rotation center of the auger 34. Then, the ice that has reached the ice discharge ports 71 and 71 and whose density per unit space has been increased is changed by the discharge guide surface 66 in the downward direction and is pushed toward the ice discharge ports 71 and 71. The ice falls from the ice discharge ports 71, 71 toward the ice passage ports 53 of the auger 34. In addition, the ice pushed out to each ice discharge port 71 contacts the rotating shaft 56 of the auger 34, the support boss part 52, the spoke part 51, etc., and falls and falls. Ice that has fallen into each ice passage port 53 from a portion adjacent to the rotation center of the auger 34 passes through the inner cylinder portion 81 of the reservoir tank 37 and falls into the ice storage chamber 105.

  On the other hand, the auger type ice making machine 30 that generates ice without installing the ice collecting member 35 in the upper opening of the auger 34 operates as follows. The ice moved to the upper opening of the auger 34 is turned by the discharge guide surface 64A and the guide surface 67 of the fixed blade 64 as shown in FIG. Since 35 is not disposed (because the ice collecting portion S is not formed), it freely falls from the portion adjacent to the inner peripheral surface of the auger 34 toward each ice passage port 53. Therefore, the ice that has fallen into each ice passage port 53 from a portion adjacent to the inner peripheral surface of the auger 34 (a portion separated from the rotation center) passes through the inner cylinder portion 81 of the reservoir tank 37 in a state where the density hardly increases. Pass through and drop into the ice storage chamber 105.

  Therefore, according to the auger type ice making machine 30 of the first embodiment, the following operational effects can be obtained. First, the ice collecting position P2 by the ice pressing guide pieces 72, 72 in the ice collecting unit S is set to a position closer to the rotation center of the auger 34 than the ice peeling position P1 by the rotary blade 50 of the auger 34. Torque load on the driving means 36 accompanying collection is reduced. Therefore, failure of the driving means 36 is less likely to occur, and the manufacturing cost can be reduced because the driving means with a small output can be used. And since the ice collected in the ice collecting part S moves toward the rotation center of the auger 34, the ice collection speed is gradually reduced to improve the collection efficiency, and the rotation speed of the auger 34 is increased to make ice. Even if the efficiency is improved, a significant decrease in ice collection efficiency can be suppressed. Further, the drive means 36 for rotating the auger 34 is disposed above the auger 34 in the ice making mechanism 32, and the drive means 36 is connected to the upper part of the auger 34 so that the auger 34 is suspended. The ice peeled from the refrigeration casing 33 by the rotary blade 50 of the auger 34 can be dropped and released into the auger 34 from the upper opening (ice passing port 53) of the auger 34, which is shown in FIG. Unlike the auger type ice making machine 10, it is not necessary to push the generated ice to the ice discharge chute 26 through the ice discharge port 25, so that the ice transport efficiency can be improved.

  In the ice collecting section S, the ice pressing guide pieces 72 and 72 provided on the upper surface of the ice collecting member 35 and the protrusion 65 provided on the lower surface of the base member 39 prevent the ice from rotating with the rotation of the auger 34. Originally, the ice can be appropriately collected while moving toward the center of rotation of the auger 34. Further, since the ice collecting member 35 can be detachably attached to the auger 34, the ice collecting member 35 is attached so that the density per unit space is increased. In addition, by not attaching the ice collecting member 35, it is possible to make the specification for generating ice with a low density per unit space, and it is possible to easily cope with both specifications depending on the presence or absence of the ice collecting member 35. Moreover, it is possible to change to the reverse specification while being implemented according to any specification.

  In the auger type ice making machine 30 according to the first embodiment, the ice making operation is performed in a state where the ice making mechanism portion 32 including the refrigeration casing 33 and the auger 34 is immersed in the ice making water stored in the reservoir tank 37. Therefore, the ice-making water is supplied to the ice-making mechanism 32 in an appropriately cooled state, and the generation of ice on the inner wall surface 40 (ice-making surface 43) of the refrigeration casing 33 is promoted, so that improvement in ice-making efficiency can be expected. Then, the reservoir tank 37 and the ice making water stored in the reservoir tank 37 exhibit a function as a heat insulating material, and the heat insulating material for keeping the ice making mechanism portion 32 in a low temperature state becomes unnecessary, and the ice making machine Manufacturing costs can be reduced. Even if a heat insulating material is attached to the outer wall surface 41 of the refrigeration casing 33 in order to suppress the formation of ice, only a small amount of heat insulating material is used for this, so the manufacturing cost of the ice making machine is hardly affected. Absent. Furthermore, since the reservoir tank 37 is disposed around the ice making mechanism 32, the ice making machine itself can be downsized.

(Modification 1)
FIG. 8 is a schematic configuration diagram showing a part of the auger type ice making machine 120 according to the first modification of the first embodiment. The auger type ice making machine 120 according to the first modified example is similar to the auger type ice making machine 30 of the first embodiment described above in that the driving means 36 disposed above the auger 34 in the ice making mechanism 32 is provided above the auger 34. The auger 34 is connected to the suspension and the basic configuration of the refrigeration casing 33, the auger 34, the ice collecting member 35 and the like constituting the ice making mechanism 32 is the same as that of the first embodiment. The reservoir tank 37 is eliminated. That is, the auger type ice making machine 120 according to the first modification is configured so that the space defined between the refrigeration casing 33 and the auger 34 functions as an ice making water storage unit 126 that stores ice making water. A disc-shaped member 122 having an opening 122A having the same diameter as the inner diameter of the auger 34 is fixed to the lower end portion of the refrigeration casing 33, and between the upper surface of the disc-shaped member 122 and the lower end portion of the auger 34. A seal member 124 is provided to prevent the ice making water stored in the ice making water storage unit 126 from leaking.

  Therefore, in the auger type ice making machine 120 according to the modified example 1, the auger 34 and the ice collecting member 35 disposed on the auger 34 are configured in the same manner as the auger type ice making machine 30 of the first embodiment. As in the first embodiment, effects such as a reduction in torque load on the driving means 36 accompanying the collection of ice and an improvement in ice collection efficiency can be obtained. By installing the ice collecting member 35 on the auger 34, it is possible to make the specification of generating ice with a higher density per unit space, and by not mounting the ice collecting member 35, the density per unit space can be increased. Low ice production specifications can be achieved. Further, since the generated ice can be dropped and released into the auger 34 from the upper opening (ice passing port 53) of the auger 34, the generated ice is generated like the conventional auger type ice making machine 10 shown in FIG. It is not necessary to push out the formed ice to the ice discharge chute 26 through the ice discharge port 25, and the ice transport efficiency can be improved. Although not shown in FIG. 8, if a heat insulating material is provided outside the refrigeration casing 33 as necessary, an improvement in the cooling efficiency of the refrigeration casing 33 can be expected.

(Modification 2)
FIG. 9 is a schematic configuration diagram illustrating a part of the auger type ice making machine 130 according to the second modification of the first embodiment. In the auger type ice making machine 130 according to the second modified example, the driving means 36 disposed above the auger 34 in the ice making mechanism portion 32 is provided at the upper part of the auger 34 in the same manner as the auger type ice making machine 30 of the first embodiment. The auger 34 is suspended by being connected to the basic structure of the refrigeration casing 33 and the ice collecting member 35 constituting the ice making mechanism 32. The shape has been changed. That is, the auger 34 has a bottomed cylindrical shape that opens upward, and a cylindrical member 132 having an opening 132B having the same diameter as the inner diameter of the auger 34 is provided at the bottom 132A of the inner end edge of the opening 132B. Is fixed in a state aligned with the lower end portion of the auger 34, and the auger 34 is provided with an ice making water storage portion 134 capable of storing ice making water. Therefore, the refrigeration casing 33 faces the inside of the ice making water storage portion 134 and is located outside the auger 34. The outer wall portion 132C of the cylindrical member 132 is located outside the refrigeration casing 33, and the ice making of the auger 34 is performed. When a predetermined amount of ice making water is stored in the water storage part 134, the refrigeration casing 33 is disposed in the ice making water.

  Accordingly, in the auger type ice making machine 130 according to the modified example 2, the ice collecting member 35 disposed on the upper part of the auger 34 is configured in the same manner as the auger type ice making machine 30 of the first embodiment. In the same manner as above, effects such as reduction of torque load on the driving means 36 accompanying ice collection and improvement of ice collection efficiency can be obtained. By installing the ice collecting member 35 on the auger 34, it is possible to make the specification of generating ice with a higher density per unit space, and by not mounting the ice collecting member 35, the density per unit space can be increased. Low ice production specifications can be achieved. Further, since the generated ice can be dropped and released into the auger 34 from the upper opening (ice passing port 53) of the auger 34, the generated ice is generated like the conventional auger type ice making machine 10 shown in FIG. It is not necessary to push out the formed ice to the ice discharge chute 26 through the ice discharge port 25, and the ice transport efficiency can be improved. Furthermore, since the refrigeration casing 33 is immersed in the ice making water stored in the ice making water storage section 134 provided in the auger 34, the ice making water is supplied for ice making in an appropriately cooled state. Ice generation on the ice making surface of the casing 33 is promoted to improve ice making efficiency. Moreover, since the ice making water storage part 134 is provided in the auger 34, the auger type ice making machine 130 as a whole can be reduced in size. Furthermore, since the ice making water stored in the ice making water storage part 134 of the auger 34 functions as a heat insulating material for the refrigeration casing 33, a heat insulating material for keeping the ice making mechanism part 32 in a low temperature state becomes unnecessary. Moreover, even if it installs a heat insulating material in order to suppress the production | generation of ice on the external wall surface 41 of the freezing casing 33, the heat insulating material used for this may be a small amount. Therefore, since the heat insulating material is unnecessary or becomes a small amount, the material cost and the molding cost of the heat insulating material can be reduced, and the manufacturing cost of the ice making machine can be suppressed. Furthermore, since the reservoir tank 37 is disposed around the ice making mechanism 32, the ice making machine itself can be downsized.

(Modification 3)
FIG. 10 is a schematic configuration diagram illustrating a part of the auger type ice making machine 140 according to the third modification of the first embodiment. The auger type ice making machine 140 according to the third modification is similar to the auger type ice making machine 30 according to the first embodiment described above by connecting the driving means 36 disposed above the ice making mechanism 32 to the upper part of the auger 34. The configuration of the refrigeration casing 33 is changed while the basic configuration of the refrigeration casing 33 and the ice collecting member 35 constituting the ice making mechanism 32 is the same as that of the first embodiment. It is. That is, the refrigeration casing 33 has a cylindrical portion 142A having a smaller diameter than the inner diameter size of the auger 34, and extends radially outward from the lower end portion of the cylindrical portion 142A to have the same outer diameter as the outer diameter of the refrigeration casing 33. The cylindrical member 142 composed of the bottom 142B is fixed in a state where the outer edge of the bottom 142B is aligned with the lower end of the refrigeration casing 33, and the ice-making water storage 144 that can store ice-making water is The configuration is provided in the casing 33. Therefore, the auger 34 is located inside the refrigeration casing 33 with the ice making water reservoir 144 facing the inside, and the cylindrical portion 142A of the cylindrical member 142 is located inside the auger 34. When a predetermined amount of ice making water is stored in the water storage part 144, the auger 34 is disposed in the ice making water.

  Therefore, in the auger type ice making machine 140 according to the modified example 3, the auger 34 and the ice collecting member 35 disposed on the upper part of the auger 34 are configured in the same way as the auger type ice making machine 30 of the first embodiment. As in the first embodiment, effects such as a reduction in torque load on the driving means 36 accompanying the collection of ice and an improvement in ice collection efficiency can be obtained. By installing the ice collecting member 35 on the auger 34, it is possible to make the specification of generating ice with a higher density per unit space, and by not mounting the ice collecting member 35, the density per unit space can be increased. Low ice production specifications can be achieved. Further, since the generated ice can be dropped and released into the auger 34 from the upper opening (ice passing port 53) of the auger 34, the generated ice is generated like the conventional auger type ice making machine 10 shown in FIG. It is not necessary to push out the formed ice to the ice discharge chute 26 through the ice discharge port 25, and the ice transport efficiency can be improved. Further, since the refrigeration casing 33 and the cylindrical member 142 are cooled, the ice making water stored in the ice making water storage unit 144 is supplied for ice making in an appropriately cooled state, and the ice making of the refrigeration casing 33 is made. The generation of ice on the surface is promoted to improve ice making efficiency. Moreover, since the ice making water storage part 144 is provided in the freezing casing 33, the auger type ice making machine 140 as a whole can be downsized. Although not shown in FIG. 10, if a heat insulating material is provided outside the refrigeration casing 33 as necessary, an improvement in the cooling efficiency of the refrigeration casing 33 can be expected.

  FIG. 11 is a schematic configuration diagram showing a part of the auger type ice making machine 110 according to the second embodiment of the present invention. In the auger type ice making machine 110 according to the second embodiment, an ice collecting unit S that collects the ice peeled off by the rotary blade 50 of the auger 34 and conveyed upward is provided above the refrigeration casing 33 in the ice making mechanism unit 32. Yes. That is, the ice discharge port 114 provided at the upper end of the cylinder 20 is provided to be deviated toward the rotation center side of the auger 34 with respect to the ice peeling position P1 by the rotary blade 50 of the auger 34. In addition, an inclined portion (ice guide portion) 112 that guides the ice transported by the auger 34 toward the ice discharge port 114 is tapered toward an upper portion of the ice making mechanism portion 32 of the cylinder 20 as it goes upward. It is formed into a shape. Between the ice discharge port 114 and the inclined portion 112, a fixed blade (rotation restricting portion) 113 for restricting the conveyed ice from rotating together with the auger 34 is disposed. That is, the ice collection position P2 in the ice collecting unit S by the fixed blade 113 is set to a position closer to the rotation center of the auger 34 than the ice peeling position P1 by the rotary blade 50 of the auger 34. As a result, the ice generated on the ice making surface 43 of the refrigeration casing 33 is peeled off at the ice peeling position P1 by the rotary blade 50 of the auger 34 that rotates at a constant speed by the driving means, and then conveyed to the ice collecting part S to be inclined. It moves to the fixed blade 113 while passing through 112, and is collected at the ice collection position P <b> 2 in the fixed blade 113, and then discharged to the outside of the ice making machine through the ice discharge port 114.

  Therefore, in the auger type ice making machine 110 according to the second embodiment, the ice collecting position P2 in the ice collecting unit S by the fixed blade 113 is closer to the rotation center of the auger 34 than the ice peeling position P1 by the rotating blade 50 of the auger 34. As a result, the torque load on the driving means 36 associated with collecting ice in the ice collecting unit S is reduced. Since the ice collection by the fixed blade 113 is performed at a position close to the center of rotation of the auger 34, the ice collection speed is reduced, the collection efficiency is improved, and the rotation speed of the auger 34 is increased. Even if the ice making efficiency is improved, it is possible to suppress a significant decrease in ice collecting efficiency.

The surface 264a is configured to peel off ice. Further, the ice making mechanism 230 pushes up the transported space 257 between the ice making surface 264 a and the outer peripheral surface 252 a of the auger 250 with the rotary blade 254 while rotating the auger 250, and the refrigeration casing 264 and the guide member 274.

In addition, a plurality of water supply holes 248 penetrating in the inner and outer directions of the shaft portion 245 are provided in the lower portion of the shaft portion 245 so as to be spaced apart from each other in the circumferential direction of the shaft portion 245.

The inclined guide surface 274b is formed so as to be inclined upward from the radially outer side to the inner side of the guide member 274. Further, when the guide member 274 is attached to the refrigeration casing 264 with a screw or the like so as to cover the upper portion of the spoke portion 259, the plane portion extends in parallel to the upper end surface of the spoke portion 259, and the inclined guide surface 274b is the spoke. It is comprised so that it may extend in parallel with respect to the slope part 259c of the part 259. FIG. Note that the guide member 274 of the third embodiment is configured such that its position in the radial direction is regulated by a holding piece 266a provided upright on the outer peripheral edge of the refrigeration casing 264. When the guide member 274 is attached to the refrigeration casing 264, the connection boss portion 260 protrudes from the upper surface of the guide member 274 through the insertion hole 274a, and the lower surface of the guide member 274 is iced against the upper surface of the spoke portion 259. The spoke portions 259 are configured to move along the lower surface of the guide member 274 with the rotation of the auger 250.

In other words, the connection structure between the output shaft portion 277 of the driving means 276 and the power transmission portion 258 of the auger 250 is configured to allow play and absorb the positional deviation of the output shaft portion 277. As described above, the ice making mechanism unit 230 is configured to hold the auger body 252 with the bearing unit 244 and align the rotation center of the auger 250. Therefore, the ice making mechanism unit 230 only needs to be able to transmit the rotational drive of the drive unit 276. When connecting the shaft portion 277 to the power transmission portion 258, it is not necessary to strictly align the rotation center of the auger 250 and the output shaft portion 277, and the dimensional accuracy can be set low. Further, in the ice making operation, the thrust load and the radial load applied to the auger 250 are supported by the bearing portion 244, so that the load from the auger 250 on the driving means 276 can be reduced. That is, since the frame 278 that supports the driving means 276 and the connection structure between the output shaft portion 277 and the power transmission portion 258 require less strength, a simple structure can be adopted to reduce the cost.

  The ice making mechanism 230 has a configuration in which an ice discharge passage 235a penetrating vertically in the axial direction of the auger body 252 is provided inside the auger 250 and is collected radially inward by a spoke portion 259 which is an ice guide portion. The same effects as the ice making mechanism 32 of the first embodiment are produced. Further, since the ice discharge path 235a is configured to be shared by the cylindrical body 235 of the water supply part 234, the number of parts can be reduced, and the ice making mechanism 230 can be downsized. Further, the ice making mechanism section 230 is configured such that the output shaft section 277 is inserted into the shaft groove 260a of the power transmission section 258 from above, and the output shaft section 277, the power transmission section 258, and the like only by pulling the drive means 276 upward. Can be easily disconnected. The ice making mechanism unit 230 can easily pull the auger 250 upward from the bearing unit 244 by removing the driving unit 276, the gantry 278, and the guide member 274 from the refrigeration casing 264. Moreover, the ice making mechanism 230 can remove the auger 250 without draining the ice making water from the ice making water storage space. That is, the ice making mechanism unit 230 can easily perform maintenance work such as cleaning or replacement of the auger 250.

For example, the rotation restricting portion 65 may be formed such that a plurality of groove portions are provided in a radial shape so as to be entirely corrugated.

  In the first embodiment and the first to third modifications of the first embodiment, the configuration in which the driving means 36 for rotating the auger 34 is disposed above the ice making mechanism portion 32 is exemplified. However, the driving means is provided below the ice making mechanism portion 32. The structure which arrange | positions 36 may be sufficient. That is, the driving means 36 is fixed to the frame 38 below the ice making mechanism 32, the rotating shaft 56 connected to the upper portion of the auger 34 is extended downward, and the lower end of the rotating shaft 56 is connected to the driving means 36. Good.

  In Examples 1 to 3, the auger type ice making machine having only the inner wall surface as the ice making surface is illustrated, but the present invention is also applied to the auger type ice making machine having both the inner wall surface and the outer wall surface as the ice making surface. Is possible.

  As in the modified example of the guide member 326 shown in FIG. 17, a rotation restricting portion 327 that assists the smooth movement of ice in the radial direction may be provided on the lower surface of the guide member 326. The guide member 326 of the modified example is provided with a plurality of rotation restricting portions 327 extending obliquely on the lower surface of the plane portion so as to intersect the radial direction and projecting downward. In the modified example, the phase is shifted by 90 °. Four rotation restricting portions 327 are provided while being shifted. The rotation restriction portion 327 of the modified example is formed so as to extend from the front side to the rear side in the rotational direction of the auger 250 from the inner side to the outer side in the radial direction. At this time, the spoke portion 259 of the power transmission portion 258 may have a linear shape instead of a shape that is bent halfway. The rotation restricting portion 327 and the spoke portion 259 of the power transmission portion 258 are configured not to interfere with each other.

  If the power transmission part of Example 3 connects the output shaft part of the drive means and the auger body and the auger body can be rotated by the rotational drive of the output shaft, the power transmission part is between the output shaft and the rotation center of the auger. It is good also as a structure which absorbs position shift of the radial direction. As described above, since the auger is positioned by aligning the rotation center with the bearing portion, it is not necessary to strictly align the output shaft portion of the driving means with the rotation center of the auger. That is, the power transmission unit is configured to absorb the positional deviation in the radial direction between the output shaft unit and the rotation center of the auger, so that the assembly of the output shaft unit and the power transmission unit is facilitated, and the driving means Assembly accuracy and dimensional accuracy of the power transmission unit can be set low. In addition, the load on the driving means can be reduced.
