Description

  The present invention relates to an ice making machine provided with an ice making mechanism chamber in which an ice making mechanism is disposed, and a machine room provided side by side on the ice making mechanism chamber and partitioned by a partition wall. is there.

  An automatic ice maker that continuously manufactures a large amount of ice blocks is suitably used in facilities such as coffee shops and restaurants and other kitchens. As an automatic ice maker, an ice storage that stores ice blocks such as ice cubes, and an ice making unit that is mounted on the top of the ice storage and has an ice making mechanism and a freezing mechanism, the necessary ice making amount, ice block storage amount, etc. There is known a stack-on type that can be appropriately combined in accordance with (see, for example, Patent Document 1).

  As shown in FIG. 6, the ice making unit 10 is formed by joining a metal material 14 a having an L-shaped cross section, and a frame body 14 having a rectangular parallelepiped shape, and assembled to the front, rear, left, right, and top surfaces of the frame body 14. The main body 12 is composed of the metal cover 16. Inside the main body 12, an ice making mechanism chamber 20 and a machine chamber 22 are defined right and left by a partition plate 18 attached to the frame body 14. The ice making mechanism chamber 20 houses and arranges an ice making mechanism (not shown) for producing ice blocks, and the machine room 22 has a freezing mechanism 24 such as a compressor CM and a condenser CD, and an electrical box CB. Various devices such as these are stored and arranged.

The ice making unit 10 cools the ice making chamber of the ice making mechanism by the refrigeration mechanism 24 to produce an ice block, and the ice block detached from the ice making chamber is illustrated through an ice passage opening at the bottom of the ice making mechanism chamber 20. Not to be released into the ice store. Here, it is essential for the ice making mechanism chamber 20 that the ice making mechanism is not affected by temperature fluctuations of the external or adjacent machine chamber 22 in order not to impair the ice making efficiency of the ice making mechanism. Further, since the ice making mechanism chamber 20 communicates with the ice storage through an ice passage, if the temperature of the ice making mechanism chamber 20 becomes high, there is a risk of causing melting of ice blocks stored in the ice storage. . Therefore, in the ice making unit 10, heat insulation of the ice making mechanism chamber 20 is achieved by attaching a heat insulating material 26 such as urethane foam to a portion of the metal cover 16 and the partition plate 18 facing the ice making mechanism chamber 20.

  Since the main body 12 of the ice making unit 10 has a structure in which the metal cover 16 is attached to the frame body 14, it is difficult to provide a heat insulating material 26 at a portion facing the frame body 14 in the metal cover 16, and the portion is insulated. Even if the material 26 is provided, it is difficult to ensure a sufficient heat insulation thickness. That is, the frame 14 exposed to the ice making mechanism chamber 20 cannot be sufficiently provided with the heat insulating material 26, so that the heat insulating performance is inferior, and the ice making mechanism chamber 20 is not suitable in summer or when the temperature of the installation environment of the ice making machine is high. There is a risk that the ice-making efficiency of the ice-making mechanism will decrease due to the temperature rise.

  Further, since the inner surface of the ice making mechanism chamber 20 is constituted by the heat insulating material 26 having fine cell holes, it is pointed out that the ice making mechanism chamber 20 is difficult to clean regardless of being easily contaminated.

  That is, the present invention has been proposed in order to suitably solve these problems inherent in the ice making machine according to the prior art, and provides an ice making machine provided with an appropriately insulated ice making mechanism chamber. The purpose is to do.

Is provided. Further, the upper surface of the bottom plate portion 42b is formed so as to be inclined downward toward the drain hole 64b, and the bottom plate portion 42b located on the lower side of the ice making mechanism receives splashed water, defrosted water, etc. dripping from the ice making mechanism. Thus, it functions as a drain pan 64 that discharges to the outside through the drain hole 64b. Thus, by forming the drain pan 64 integrally with the bottom plate part 42b of the heat insulation box 40, the number of parts can be reduced.

  The heat insulation box 40 is attached with the side panel 58 of the panel portion 54 facing the right surface of the partition plate portion 42a with a gap S between the partition plate portion 42a and the bottom plate portion 42b.

The reinforcing material 66 extending to the front side has a rising portion 66a at the left end, and the rising portion 66a reinforces the front side between the left plate portion 42c and the left outer panel 46A.

(Effects of Example)
Next, the operation of the ice making machine according to the embodiment will be described. The ice making mechanism chamber 34 is defined by a heat insulating box 40 having a heat insulating structure in which the left and right side walls, the rear wall, and the bottom wall are filled with a heat insulating material 48 between the inner panel 42 and the outer panels 58, 44, 46A, 46B. Made. The heat insulating box 40 is a three-layer heat insulating structure including an inner panel 42, outer panels 58, 44, 46A, 46B and a heat insulating material 48, and is provided between the inner panel 42 and the outer panels 58, 44, 46A, 46B. Since there is no air flow in the gap S, the heat insulation from the outside can be improved as compared with a conventional wall structure configured by attaching a sheet-like heat insulating material to a metal cover. Further, by using the right wall of the heat insulating box 40 as a partition wall 38 that partitions the ice making mechanism chamber 34 and the machine chamber 36, the temperature of the machine chamber 36 is increased due to installation of a device that generates heat such as a compressor. However, since the partition wall 38 has high heat insulation, it is possible to suppress the ice making mechanism chamber 34 from being affected by the heat of the machine chamber 36. As described above, the ice making mechanism chamber 34 is not easily affected by heat even if the installation environment or the machine room 36 is heated, and the ice making mechanism can exhibit a predetermined ice making capability. Furthermore, since the heat insulation between the machine room 36 and the inside of the ice storage is improved as a three-layer heat insulating structure including the base panel 56, the bottom panel 44, and the heat insulating material 48 at the bottom of the machine room 36, the ice storage It is possible to suppress the thermal influence of the machine room 36 on the ice block stored in

  In the ice making mechanism chamber 34, the metal material 52 a of the frame 50 necessary for attaching the front cover 60 </ b> A only extends to the front upper edge, and the metal material 52 a exposed to the ice making mechanism chamber 34 is exposed. Is kept to a minimum. The ice making mechanism chamber 34 is only exposed to the heat insulating material attached to the front cover 60A and the upper surface cover 60B, and the heat insulating material exposed to the ice making mechanism chamber 34 is minimized. The inner panel 42 of the heat insulating box 40 is a molded product of synthetic resin, and the surface facing the ice making mechanism chamber 34 is smoother than the heat insulating material in which fine cell holes are exposed, and there is no seam. Therefore, it is difficult for dirt to adhere and easy cleaning, and the hygienic state of the ice making mechanism chamber 34 can be suitably maintained. Further, the bottom panel 44 constituting the bottom surface of the main body 32 in the ice making unit 30 is a ceiling surface of the ice storage, but the bottom panel 44 is a synthetic resin molded product, and the surface facing the inside of the ice storage is smooth. Therefore, it is difficult for dirt to adhere, and it is easy to clean, and the hygienic condition inside the ice storage can be suitably maintained.

  By making the partition wall 38 bend in the middle of the front-rear direction, the function as a support for supporting the main body 32 can be improved compared to a straight wall, and the strength of the entire main body 32 can be increased. Further, when the heat insulating box 40 is manufactured, the partition wall 38 can be prevented from falling to the ice making mechanism chamber 34 due to heat generated when the foaming raw material injected into the gap S is foamed. Then, by pulling out the electrical box CB from the machine room 36, equipment such as the cooling fan FM can be maintained using the recess 36a, and the maintainability of equipment installed in the machine room 36 can be improved.

  In the stack-on type like the ice making machine, since the ice making unit portions 30 are stacked, the strength of the main body 32 is required. The ice making mechanism disposed in the ice making mechanism chamber 34 and the equipment installed in the machine room 36 can be maintained, and the ice making mechanism chamber 34 is also required to have heat insulation. That is, if the entire main body 32 is simply formed of a heat insulating box having a lower strength than the metal material 52a, all of the above-described conditions cannot be satisfied. Here, the ice making unit 30 of the embodiment is formed by integrally foaming the bottom of the partition wall 38 and the heat insulation box 40 constituting the bottom of the main body 32 and the bottom of the machine room 36, so that the strength of the central portion and the bottom of the main body 32 is increased. Since the metal material 52a of the frame 50 is disposed on the front surface and the upper surface of the heat insulating box 40 that requires maintenance, all three points of maintenance, strength, and heat insulating properties are satisfied. Can do.
