In each of these types of ice machines, as a basic configuration, an ice storage and a machine room are defined in a substantially box-shaped ice machine body, and a condenser, which constitutes a refrigerating device, is provided in the machine room. Basic components such as a compressor, a dehydrator, and a fan motor, and an electric board are provided. An ice making mechanism of any one of the above-described types is disposed above the inside of the ice storage, and the ice cubes produced by the ice making mechanism during the ice making operation of the refrigerating device are dropped and discharged during the deicing operation. Then, they are temporarily stocked in the ice storage.

FIG. 11 is an exploded perspective view schematically showing an upper portion of a main body of an ice maker of a closed type cell injection type, in which a space 18a inside an ice storage 18 defined inside the ice maker main body 12 is provided. A closed cell injection type ice making mechanism 24 is provided. The ice making machine main body 12 is illustrated as a box having an opening at the top and front surfaces of the ice storage 18, and a rectangular upper inner plate 4 is formed at the top opening 12b.
6 and the top plate 44 for covering the upper inner plate 46 is set from above and fixed with screws 80 from both sides, so that the upper inner plate 46 and the top plate 44 can be attached to and detached from the ice making machine main body 12. Attached to. As described above, since the top plate 44 is fixed to the ice making machine main body 12 with the screw 80 so as not to be easily moved, the top plate 44 comes off and the ice making mechanism section 24 is easily exposed. There are no advantages, such as preventing pests such as rats and cockroaches from entering the ice making machine main body 12 through the gap of the top plate 44, and preventing a decrease in heat insulation performance and heat insulation efficiency due to displacement of the top plate 44. is there. A horizontally long rectangular front panel 66 is detachably attached to the front side of the front opening 12a of the ice making machine body 12 by hooks (not shown) and screws 81 and the like. 24 is covered.

[0004] In addition to the form in which the top plate 44 and the front panel 66 are attached to the ice making machine main body 12 separately from the form shown in FIG. As shown in FIG. 13, an engaging piece 74 formed on the lower edge of the front end of the top plate 44 and an engaging piece 78 formed on the upper edge of the front panel 66 are engaged with each other to form the two members 44, 66.
And the top plate 44 and the front panel 66 are integrally attached to the ice making machine main body 12. That is, in the attachment mode shown in FIG. 12, the engagement hole 82 formed in the rear end edge of the top plate 44 is engaged with the hook-shaped engagement piece 84 arranged on the upper rear surface of the ice making machine main body 12, and then, Front panel 6

Therefore, the structure is such that the top plate 44 is suitably fixed without moving.

[0005]

By the way, in the ice maker of the type shown in FIG. 11 in which both sides of the top plate 44 are screwed, the ice maker is installed adjacent to a refrigerator, a cupboard or a wall. When the ice making mechanism 24 in the ice storage 18 is inspected or maintained at an appropriate time, it is necessary to secure a space where a tool for removing the screw 80 can be used. Therefore, it is necessary to temporarily retreat various devices adjacent to both sides, but if this is not possible, the ice maker must be pulled out and the screw 80 must be removed before the maintenance work is performed. There are inherent shortcomings. Further, the upper inner plate 46 is not fixed to the ice making machine main body 12, and when the top plate 44 is removed from the ice making machine main body 12, the upper inner plate 46 is easily displaced and moved to expose the internal ice making mechanism 24. Therefore, a user who is not familiar with the mechanism or the like can enter the inside and touch the ice making mechanism 24. At this time, the ice making mechanism 24 is operated and the hands are caught or electric wiring is interrupted. No measures were taken to prevent accidents such as electric shocks. Furthermore, since the screw 80 for attaching the top plate 44 is exposed to the outside of the side surface of the ice machine, a disadvantage that the appearance is deteriorated is pointed out.

The top plate 4 shown in FIGS.
In the ice making machine of the type in which the top plate 44 and the front panel 66 are engaged with each other, there is an advantage that the top plate 44 can be suitably fixed. In addition to the necessity of bending work and joining parts for performing the steps, the number of work steps for assembling these members 44 and 66 increases, so that assembling takes time and the manufacturing cost increases. Moreover, since the top plate 44 and the front panel 66 are connected in an L-shape, both members 4
The attachment and detachment of the 4,66 requires considerable skill, and has a disadvantage that an unskilled person cannot easily perform the attachment / detachment operation. Then, since the top plate 44 and the front panel 66 are integrally removed, the front opening 12a and the top opening 12b are largely opened, and the ice making mechanism 24 is completely exposed, as described above. There is a major problem in terms of safety. Further, the screws 8 for fixing the front panel 66
6 is exposed outside the front of the ice making machine, so that a disadvantage that the appearance is deteriorated is pointed out.

Further, since the upper inner plate is fixed from above by an engaging member, even if a wall or a refrigerator is adjacent to both sides of the ice making machine, the upper inner plate is attached and detached without moving the ice making machine. This has the advantage that maintenance work can be performed easily and in a short time.

Further, the front panel is attached to the ice making machine body with the front inner plate fixed to the front opening of the ice making machine body by the engaging member, so that even if the front panel is removed from the ice making machine body, Since the inner plate covers the ice making mechanism, the ice making mechanism cannot be directly touched with the hand, and it is possible to prevent accidents such as pinching of hands or electric shock by electric wiring. Further, since the front panel can be attached to the ice making machine without using any screws, the screws are not exposed to the outside of the ice making machine, and the appearance is not deteriorated. In addition, since the top plate and the front panel are separately configured, and these members can be easily attached to and detached from the ice maker, there is an advantage that an unskilled person can perform attachment / detachment work.
