Description

  The present invention relates to an ice making chamber, and more particularly to an ice making chamber in which a plurality of ice making chambers in which ice is formed by partition plates arranged in a lattice shape are defined.

  For example, as an automatic ice maker that continuously manufactures square ice used in restaurants such as coffee shops, there is a jet type automatic ice maker that freezes ice-making water in a number of ice-making chambers that open downward. Are known. Describing the schematic configuration of this automatic ice maker, an ice making chamber in which a large number of ice making chambers opening downward are defined at predetermined positions of a housing forming the ice making body, and the ice making chamber Below, an ice making water tank is arranged at a predetermined interval. Ice making water is supplied from the ice making water tank to the water sprinkling pipe, and the ice making water is jetted and supplied from below to each ice making small chamber of the ice making chamber through an injection hole formed in the water sprinkling pipe. In addition, a cooling pipe led out from the refrigeration system meanders on the upper surface of the ice making chamber, and the ice making chamber is cooled by supplying a refrigerant to the cooling pipe during ice making. Accordingly, the ice making water sprayed from the water sprinkling pipe is cooled in contact with the ice making chamber of the cooled ice making chamber, and then freezes to form ice in the small chamber.

  FIG. 9 is an exploded perspective view showing a conventional ice making chamber 10 installed in such an automatic ice making machine, and has a box-shaped ice making base 14 open at the bottom, and the ice making base. 14 is basically composed of a plate-like partition plate 16 which is disposed inside 14 and defines a plurality of ice making chambers. In addition, a cooling pipe 12 led out from the refrigeration system is tightly fixed to the upper surface of the ice making chamber base 14 in a meandering manner. In the partition plate 16, the partition plate extending in the horizontal direction and the partition plate extending in the vertical direction are referred to as the horizontal partition plate 16a and the vertical partition plate 16b, respectively.

  As another type of ice making chamber, as shown in Patent Document 1, a cooling pipe is meandered on the upper surface of a plate-shaped ice making plate, and an ice making frame is provided on the lower surface of the ice making plate. There is a structure in which an ice making chamber is formed inside the frame.

Conventionally, when assembling each member of the ice making chamber 10, an assembling process shown in FIG. 10 has been performed. That is, the cooling pipe 12 is formed by bending a long hollow pipe in a meandering manner (bending), and the partition plate 16 and the ice making base 14 are bent from a metal plate made of stainless steel or the like ( Sheet metal processing). Then, the slits 18 opened downward at predetermined intervals in the horizontal partition plate 16a and the corresponding slits 20 opened upward at predetermined intervals in the vertical partition plate 16b are engaged with each other. Then, the respective partition plates 16a and 16b are assembled in a lattice shape (assembly). Further, as shown in FIG. 9, a plurality of protrusions 22 are provided on the upper edge of the lateral partition plate 16 a, and the protrusions 22 are provided on the top plate of the ice making chamber base 14. The partition plates 16a and 16b and the ice making base 14 are fixed by caulking by being inserted into the caulking holes 24 to be caulked. The partition plates 16 a and 16 b and the ice making chamber base 14 fixed by caulking are cleaned (pretreatment) using a chemical solution or cleaning water together with the cooling pipe 12. Then, a paste-like brazing material is applied and melted at the contact portion between the ice making chamber base 14 and the cooling pipe 12 (brazing). Thereafter, it is washed with water, chemicals, etc. (post-treatment), and then immersed in a liquid such as tin and plated (hot-tin plating), and the assembly of the ice making chamber 10 is completed.
JP 2000-329435 A

  Each member of the ice making chamber 10 is assembled by going through the above process, but as described above, only the cooling pipe 12 and the ice making substrate base 14 are fixed by brazing. The horizontal partition plate 16 a and the vertical partition plate 16 b are only caulked and fixed to the ice making chamber base 14. Therefore, the coupling force between the ice making chamber base 14 and the partition plates 16a and 16b is poor, which causes the quality of the completed ice making chamber 10 to deteriorate. Further, during the cleaning (post-processing) performed after the caulking, the ice making chamber base 14 and the two partition plates 16a and 16b are loosened, causing troubles in the work, and both members coming off.

  In order to cope with such a problem, a paste-like brazing material is applied to the edge portions of the horizontal partition plate 16a and the vertical partition plate 16b that are in contact with the top plate of the ice making base 14, and both partition plates 16a are applied. , 16b and the ice making chamber base 14 are conceivable. However, it is very difficult to apply the paste wax to the narrow region of the edge portion having only the plate thickness width of the partition plates 16a and 16b, and the amount of application is easily varied. The difficulty that quality becomes unstable is pointed out. Furthermore, the binder constituting the paste brazing can also cause a surface treatment performed after brazing.

  Further, as shown in FIG. 11, the U-shaped brazing material 28 is hooked on the intersecting portion 26 of the partition plates 16a and 16b facing the opening surface side in the ice making base 14 and heated and melted. An ice making chamber 10 in which the ice making base 14 and both partition plates 14a and 14b are brazed by the brazing material 28 reaching the contact portion between the ice making base 14 and the partition plates 16a and 16b is also conceivable. However, the work of processing the brazing material 28 into a U-shape or hooking the brazing material 28 on all the intersecting portions 26 is inefficient, and the brazing material 28 is only caught on the intersecting portion 26. Therefore, it is unstable, and when the ice making chambers 10 before brazing are stacked, there is a problem that the brazing material 28 comes off or breaks.

  That is, the present invention has been proposed in order to suitably solve these problems inherent in the ice making chamber according to the prior art, and can efficiently braze the partition plate and the ice making chamber base. An object of the present invention is to propose an ice making chamber in which both members are securely fixed.

In order to overcome the above-mentioned problems and achieve the intended purpose, an ice making chamber according to the present invention is a partition in which a plurality of plate-like partition plates are assembled in a lattice shape with a predetermined spacing in the vertical and horizontal directions. In an ice making chamber in which a plurality of ice making chambers in which ice is formed are defined by arranging members on the ice making chamber base,
At an edge contacting the ice making chamber base in each partition plate extending in at least one of the vertical direction and the horizontal direction, and in a portion close to an intersection with each partition plate extending in the other direction Each notch is recessed,
A linear brazing material that is arranged in a plurality of notches aligned along each partition plate extending in the other direction and extends so as to be adjacent to each other along the partition plate is used as the partition plate and the ice chamber base. The partition member and the ice-making chamber base are brazed by melting while sandwiched between and.

  According to the ice making room according to the present invention, the partition member and the ice making room base are provided with the notch portion for setting the linear brazing material at the edge contacting the ice making room base of the partition plate extending in one direction. Can be brazed efficiently. In addition, since the brazing material is positioned in the notch, the partition member and the ice making chamber base can be securely fixed without causing unevenness in brazing.

  Further, when the brazing material is disposed along both the vertical and horizontal directions and brazed, the partition member and the ice making chamber base are more firmly fixed.

  Next, a preferred embodiment of the ice making chamber according to the present invention will be described below with reference to the accompanying drawings. In addition, the same code | symbol is attached | subjected about the same member demonstrated by the prior art. Further, in the following description, in the conventional ice making room, a case where the caulking that fixes the partition plate and the ice making room base is eliminated is shown, but the ice making room according to the present invention can also use caulking. is there.

  FIG. 1 is a perspective view showing an ice making chamber 30 according to the first embodiment. The ice making chamber 30 includes a partition member 34 in which a plurality of plate-like partition plates 32 are assembled in a lattice shape with predetermined intervals in the vertical and horizontal directions, and a box-shaped ice making device that opens downward (one side). A plurality of ice making chambers 36 in which ice is formed are defined by accommodating and arranging the partition member 34 in the ice making room base 38. As described in the description of the prior art, the partition plate 32 according to the first embodiment is arranged along the longitudinal direction with the lateral partition plate 32a disposed along the short direction of the ice making chamber base 38. The description will be made by distinguishing the vertical partition plate 32b.

  The vertical partition plate (partition plate extending in the other direction) 32b is formed by forming a metal such as stainless steel into a thin plate shape as shown in FIG. It is set slightly smaller than the internal dimension of the ice making chamber base 38 in the longitudinal direction. A plurality of slits 20 (five in the embodiment) are provided at regular intervals from the upper end edge 40 of the vertical partition plate 32b to a substantially central position in the vertical direction.

  Further, the horizontal partition plate (partition plate extending in one direction) 32a is formed of a metal plate made of stainless steel or the like in the same manner as the vertical partition plate 32b. It is set slightly smaller than the internal dimension in the lateral direction of the base 38. Further, as shown in FIG. 2 (b), a plurality (in the first embodiment) that engages with each slit 20 of the vertical partition plate 32b from the lower end edge 42 of the horizontal partition plate 32a to a substantially central position in the vertical direction. Five slits 18 are provided at regular intervals. Further, notches 46 are respectively recessed at the upper edge 44 of the horizontal partition plate 32a that contacts the top plate 50 of the ice making room base 38 and in the vicinity of the intersection 26 with the vertical partition plate 32b. ing. That is, as shown in FIG. 3, when the lateral partition plate 32a is disposed on the ice making chamber base 38, the upper edge 44 of the lateral partition plate 32a that contacts the top plate 50 of the ice making chamber base 38, A cutout portion 46 for arranging a linear brazing material 48 is provided in a portion adjacent to each of the vertical partition plates 32b.

  The partition member 34 is configured by assembling the horizontal partition plate 32a and the vertical partition plate 32b in a lattice shape by engaging the respective slits 18 and 20, and a rectangular ice making chamber in which ice is formed. A plurality of 36 are defined. Moreover, as shown in FIG. 1, the notch part 46 provided in each horizontal direction partition plate 32a in the said partition member 34 is aligned along each said vertical direction partition plate 32b. Then, by arranging the brazing material 48 formed in a line shape in the aligned notches 46, the brazing material 48 extends along the vertical partition plates 32b. The brazing material 48 is formed by linearly molding a conventionally known brazing material, and is set to be substantially equal to the length dimension of the vertical partition plate 32b. In addition, in Example 1, although the case where the notch part 46 was provided in the said horizontal direction partition plate 32a was shown, you may provide the notch part 46 in the upper end edge 40 of the vertical direction partition plate 32b. Alternatively, the notches 46 may be provided on the left and right sides of each slit 18 of the lateral partition plate 32a, and the brazing material 48 may be disposed in a double manner along the longitudinal partition plate 32b. Thereby, the amount of the brazing material 48 is increased, and the partition member 34 and the ice making chamber base 38 can be more firmly fixed.

  The ice making chamber base 38 is a box having an opening made of stainless steel or the like, and the partition member 34 can be accommodated in a space defined therein. Further, the cooling pipe 12 led out from the refrigeration system of the ice making machine is arranged in a meandering manner outside the surface (top plate 50) facing the opening. The shape of the ice making chamber base 38 is not necessarily formed in a box shape, and may be formed in a plate shape as disclosed in Patent Document 1, for example.

  And the linear brazing material 48 which is arrange | positioned in the some notch part 46 aligned along the said vertical direction partition plate 32b and extends so that it may adjoin along this partition plate 32b is used for the said horizontal direction partition plate 32a. The partition member 34 and the ice-making chamber base 38 are brazed by melting while being sandwiched between the ice-making chamber base 38 and the ice-making chamber base 38. That is, as shown in FIG. 3, the partition member 34 is housed in the ice making chamber base 38 in a state where the brazing material 48 is disposed in the notch 46 and extends along the vertical partition plates 32b. Thus, the brazing material 48 is sandwiched between the lateral partition plate 32 a and the top plate 50. By heating the ice making chamber 30 in this state, the brazing material 48 melts and enters the gap between the vertical partition plate 32b and the top plate 50, and the upper edge portion 40 of the partition plate 32b and the top plate 50 is brazed.

(Operation of Example 1)
Next, the operation of the ice making chamber 30 according to the first embodiment will be described with reference to the assembly process diagram of FIG. When the ice making chamber 30 is assembled, a metal such as stainless steel is processed into a required shape to form the horizontal partition plate 32a, the vertical partition plate 32b, and the ice making chamber base 38 (sheet metal processing). Then, using chemicals, washing water, etc., each member is washed apart (pretreatment). In the first embodiment, since no caulking is used, it is not necessary to perform the pretreatment with both the partition plates 32a and 32b and the ice making chamber base 38 being caulked as in the prior art.

  After the pretreatment, the partition members 34 are formed by engaging the slits 18 of the horizontal partition plate 32a with the corresponding slits 20 of the vertical partition plate 32b and assembling the partition plates 32a and 32b. And as shown in FIG. 1, the linear brazing material 48 is arrange | positioned in the some notch part 46 aligned along the said vertical direction partition plate 32b. The partition member 34 is housed in the ice making chamber base 38 in a state where the brazing material 48 is disposed in the notch 46 along each vertical partition plate 32b. At this time, as shown in FIG. 3, the brazing material 48 is sandwiched at a position close to a contact portion between the vertical partition plate 32 b and the top plate 50. The cooling pipe 12 is disposed on the ice making chamber base 38 in a state where paste wax is applied to the contact portion between the outer surface of the top plate 50 and the cooling pipe 12. Then, each member is assembled and set on a brazing jig (jig set), and brazing is performed (brazing). At this time, each brazing material 48 is melted and penetrates between the vertical partition plates 32b and the top plate 50, and then solidifies, so that the partition member 34 and the ice making chamber base 38 are fixed.

  That is, since the ice making chamber 30 according to the first embodiment is provided with the notches 46 in the lateral partition plate 32a so that the linear brazing material 48 can be arranged along the respective longitudinal partition plates 32b, The brazing operation between the partition member 34 and the ice making chamber base 38 can be performed efficiently. Further, since the brazing material 48 is sandwiched and positioned by the lateral partition plate 32a and the ice making chamber base 38, unevenness in brazing does not occur. The cooling pipe 12 is also brazed to the outer surface of the top plate 50 and fixed to the ice making chamber base 38.

  The ice making chamber 30 in which each member is assembled by brazing is subjected to surface treatment (post-treatment) with a chemical solution or cleaning water. After brazing, the brazing material 48 is melted and the notch 46 is open, so that cleaning water and chemicals used for post-treatment easily flow out of the ice making chamber 36 through the notch 46. . Accordingly, during post-processing, the number of times the ice making chamber 30 is taken out of the post-processing tank can be reduced, and the time required for draining can be shortened.

  After cleaning, the ice making chamber 30 is immersed in molten tin and subjected to a plating process (molten tin plating), and the ice making chamber 30 is completed. The ice making chamber 30 is disposed in an injection type ice making machine or the like and used for ice production. Note that when ice making is performed using the ice making chamber 30, the cutout portion 46 is in an open state, so that ice is also formed therein. However, the amount of ice formed inside the notch 46 is very small and immediately melts by deicing, so it does not affect the deicing operation.

(Change example)
Although the ice making chamber 30 according to the first embodiment has been shown with no caulking, as described above, the partition member 34 and the ice making chamber base 38 of the ice making chamber 30 may be caulked and fixed as in the prior art. . However, in the conventional method of caulking and fixing, if the linear brazing material 48 is placed in the notch 46 and brazing is performed, the molten brazing material 48 may flow out of the caulking hole 24. . Therefore, as shown in FIG. 5, lock-like locking portions 56 are provided at both ends of the horizontal partition plate 32 a and the vertical partition plate 32 b, and the locking portions 56 are provided on the side portions of the ice making chamber base 38. The partition member 34 and the ice making chamber base 38 may be temporarily fixed by providing a plurality of concave cutout portions 60 that engage with the portion 56. That is, if the concave cutout portion 60 corresponding to the locking portion 56 is engaged and the partition member 34 and the ice making chamber base 38 are temporarily fixed, the caulking hole 24 is formed in the top plate 50 as in the prior art. Since there is no need to provide it, the molten brazing material 48 does not flow out of the caulking hole 24. In the ice making chamber 30 according to the modified example, pretreatment such as cleaning can be performed in a state where the partition member 34 and the ice making chamber base 38 are temporarily fixed, as in the conventional case.

  Next, an ice making chamber according to the second embodiment will be described. In addition, about Example 2, only the difference with Example 1 is demonstrated, and description is abbreviate | omitted about the same structure. Also, in the second embodiment, as in the first embodiment, a case is shown in which the notch 46 is provided in the lateral partition plate 32a, but the notch 46 may be provided in the vertical partition plate 32b. I do not care.

  FIG. 7 is a front view showing the vertical partition plate 32b of the ice making chamber 62 according to the second embodiment shown in FIG. 6, which is cut deeper than the notch 46 from the upper edge 40 of the partition plate 32b. A second notch portion (brazing material arrangement portion) 64 is provided at a portion adjacent to each slit 20 provided up to a substantially central position. That is, as shown in FIG. 6, when the two partition plates 32a and 32b are assembled and disposed on the ice making chamber base 38, the second cutout portion 64 is close to each lateral partition plate 32a. It has become.

  And the linear 2nd brazing material 66 can be arrange | positioned in the several 2nd notch part 64 aligned along each said horizontal direction partition plate 32a. That is, as shown in FIG. 7, the linear second brazing material 66 is arranged in the plurality of second notches 64 along the horizontal partition plate 32a, and the plurality of notches 46 along the vertical partition plate 32b. By disposing the first brazing material 48 in the second brazing material 66, the second brazing material 66 disposed in the second notch 64 intersects the lower part of the first brazing material 48 disposed in the notch 46, and It extends adjacently along the horizontal partition plate 32a. The length of the second brazing material 66 is set to be approximately the same as the length of the lateral partition plate 32a.

(Operation of Example 2)
Next, the operation of the ice making chamber 62 according to the second embodiment will be described. First, the horizontal partition plates 32 a and the vertical partition plates 32 b are assembled by engaging the respective slits 18 and 20 to form the partition member 34. Then, the second brazing material 66 is set in the plurality of second cutout portions 64 aligned along the horizontal partition plates 32a, and the plurality of cutout portions 46 aligned along the vertical partition plates 32b. In the state where the first brazing material 48 is disposed, the partition member 34 is accommodated in the ice making chamber base 38. At this time, as shown in FIG. 6, the second brazing material 66 arranged in the second notch 64 intersects directly below the first brazing material 48 arranged in the notch 46, and It extends close to the direction partition plate 32a. In this state, the ice making chamber 62 is set on a brazing jig and brazing is performed, whereby the partition plates 32a and 32b and the ice making chamber base 38 are fixed. That is, since the ice making chamber 62 according to the second embodiment is brazed by arranging the linear brazing materials 48 and 66 along the partition plates 32a and 32b extending in both the vertical and horizontal directions, both the partition plates 32a are used. 32b and the top plate 50 are fixed, and the partition member 34 and the ice making chamber base 38 can be more firmly fixed.

(Modification of Example 2)
In the second embodiment, the case where the second notch 64 deeper than the notch 46 is provided on the upper edge 40 of the vertical partition plate 32b is shown. The second brazing material 66 can be appropriately changed as long as the second brazing material 66 can extend along the lateral partition plates 32a. For example, as shown in FIG. 8, the second cutout portions 64 may be provided in the slits 20 provided in the vertical partition plate 32 b so as to open inside the slits 20. When the second cutout portion 64 is provided in this manner, the front notch partition plates 32a and 32b are assembled into the partition member 34, and the second cutout portion 64 and the lateral partition plate 32a are connected. The second brazing material 66 is inserted through the gap.
