Description

  The present invention relates to an ice making machine in which an ice storage assembly for storing ice blocks produced by an ice making mechanism arranged on a base member is detachably arranged on the base member.

An ice making machine (see, for example, Patent Document 1) that is integrally provided with an ice storage is configured by disposing side plates on both sides of an ice storage disposed on a support base and a rear plate on the rear surface. The storage assembly is disposed in front of the ice making mechanism on the base member on which the refrigeration mechanism and the ice making mechanism including a compressor and a condenser are installed. The ice making mechanism and the ice storage are connected to each other by an ice discharge member, and the ice blocks produced by the ice making mechanism are discharged and stored in the ice storage through the ice discharge member. Regarding the positioning and fixing of the ice storage assembly with respect to the base member, since various parts constituting the ice making mechanism are arranged behind the ice storage assembly, the ice storage assembly is positioned and fixed directly to the base member on the rear side. It was difficult to do. Therefore, conventionally, on the rear side of the ice storage assembly, the assembly itself and a bracket dedicated to positioning and fixing welded to the assembly are fixed with bolts to parts constituting the ice making mechanism, a pedestal that supports the ice making mechanism, and the like. Under the positioning, the ice storage assembly is positioned and fixed on the base member by screwing the front surface of the ice storage assembly to the front surface of the base member.

In addition, since the engaged part is provided on the gantry where the ice making mechanism is installed, there is no need to provide a special member or bolts to position the ice storage assembly, and the number of parts is reduced. Cost can be reduced.

According to a second aspect of the present invention, one of the engaging portion and the engaged portion is an engaging piece and the other is an engaging hole, and the ice storage assembly mounted on the base member is directed toward the gantry. The gist is that the engaging piece is inserted into the engaging hole and engaged by sliding.
According to the invention of claim 2, since the engaging piece is inserted into the engaging hole and engaged only by sliding the ice storage assembly along the base member, the workability is good and the positioning operation is short. You can do it in time.

The gist of the invention of claim 3 is that a plurality of the engaging portions and the engaged portions are provided apart from each other in the width direction.
According to the invention of claim 3, the ice storage assembly can be reliably positioned with respect to the base member by engaging the plurality of engaging portions and the engaged portions.

(Effects of Example)
Next, the operation of the ice making machine according to the embodiment will be described.
When the ice storage assembly 16 is positioned and fixed to the base member 10 provided with the refrigeration mechanism or the auger type ice making mechanism 14, as shown in FIG. 1, the support 20 in the ice storage assembly 16 is used as the base member. The ice storage assembly 16 is slid rearward while being placed on the upper surface of the front portion of 10. At this time, the extended portions of the both side plates 22 and 22 of the ice storage assembly 16 are in contact with the outer side surfaces of the side wall portions 10c and 10c of the base member 10 (see FIG. 5A). The solid body 16 slides straight with the side wall portions 10c, 10c as guides. Further, as described above, in a state where the support base 20 is placed on the base member 10, the lower surface level of the bottom plate 26 substantially coincides with the upper surface level of the mount 12 and a pair of engagements formed on the rear plate 24. The upper surfaces of the horizontal pieces 44b, 44b of the pieces 44, 44 are lowered from the bottom plate lower surface by the thickness dimension of the upper plate 48 in the gantry 12 (see FIG. 4A). Therefore, in the ice storage assembly 16 slid on the base member 10, the horizontal pieces 44b, 44b of the pair of engaging pieces 44, 44 are formed on the gantry 12 as shown in FIG. The bottom plate 26 is placed on the upper plate 48 of the gantry 12 while being inserted into the joint holes 46, 46. As a result, the left and right and vertical positioning with respect to the base member 10 at the rear portion of the ice storage assembly 16 is performed via the gantry 12. By sliding the ice storage assembly 16 toward the gantry 12, the ice discharge member provided in the auger type ice making mechanism 14 is connected to the ice storage 18 from the rear part of the ice storage assembly 16.

  As described above, the front flange portions 22 b and 22 b of the side plates 22 and 22 of the ice storage assembly 16 whose rear portions are positioned with respect to the base member 10 abut on the front surface of the front wall portion 10 b of the base member 10. The slide is regulated. In this state, the screw 50 inserted through the front through hole 22d of each front flange portion 22b is screwed into the front screw hole 10e of the front wall portion 10b, and the screw inserted through the side through hole 22e of each side plate 22 50 is screwed into the side screw hole 10f of the side wall 10c. As a result, the ice storage assembly 16 is positioned and fixed with respect to the base member 10. Thereafter, a rear side plate and a back plate that define the ice making mechanism chamber are disposed, and a top plate 42 is disposed over the upper part of the ice storage assembly 16 and the rear side plate and the upper portion of the back plate. Further, by disposing the heat insulating door 40 and the front panel 54 in the ice storage assembly 16, the assembly of the ice making machine is completed.

  In other words, in the embodiment, the ice storage assembly 16 is positioned with respect to the base member 10 by sliding the ice storage assembly 16 rearward with the ice storage assembly 16 placed on the base member 10 to engage the engagement pieces 44 and 44. Simply plug it into the holes 46,46. Accordingly, it is not necessary to separately provide a bracket or to perform bolt tightening work in a narrow space where the auger type ice making mechanism 14 is disposed, and positioning work is extremely simple. Further, since the ice storage assembly 16 is positioned by using the gantry 12 on which the auger type ice making mechanism 14 is arranged, conventionally used brackets and bolts can be eliminated, and the number of parts can be reduced. Manufacturing costs can be kept low. Further, since the screwing operation for fixing the ice storage assembly 16 to the base member 10 is performed on the front side and the outside side of the ice storage assembly 16, workability is good. That is, when performing maintenance such as component replacement, the ice storage assembly 16 can be easily detached from and attached to the base member 10 in a short time.

  When the condenser fan 38 is rotated, external air is sucked into the machine chamber 32 through the air suction port 56, and hot air after being cooled by air contact with the condenser 36 and the compressor 34 is sent from the air discharge port 58. Discharged. In this case, the front frame 60 disposed in the ice storage assembly 16 divides the air suction port side and the air discharge port side at the front portion of the machine room 32 as shown in FIG. The warm air is discharged from the air discharge port 58 in a direction away from the air suction port 56 without being discharged from the air suction port side of the air discharge port 58. Accordingly, a short cycle phenomenon in which a part of the warm air discharged from the air discharge port 58 is immediately sucked into the machine chamber 32 from the air suction port 56 is avoided, and the ice making capacity is reduced due to insufficient cooling of the condenser 36. Can be prevented.
