Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beverage dispenser installed in a restaurant such as a restaurant or a bar.
The present invention relates to a draft mounting structure for a beverage dispenser that can stably and reliably fix a draft for dispensing a beverage to a housing.

[0002]

2. Description of the Related Art Beer dispensers for dispensing beer from a beer storage tank in small dispenses by operating a dispensing lever provided on a dispensing cock are widely used. As a method of dispensing, a gas pressure method is adopted in which the pressure of carbon dioxide is applied to the beer in the tank, and the beer is forcibly fed to the dispensing cock by operating the dispensing lever and dispensed. I have. The beer dispenser that discharges beer from the discharge cock with gas pressure is a beer storage tank, a carbon dioxide gas cylinder for pumping beer, and a cooling mechanism (depending on the model) that cools beer passing through the beer conduit to the discharge cock. Is basically replaced with a cooling mechanism for storing the beer storage tank in a cooled state). Further, the dispenser stores the above-mentioned members in a refrigerator in a store, and raises a draft (liquid distribution tap) in which a spout cock and a column are integrated from an upper portion of the refrigerator.

[0003]

In the draft for the refrigerator, a flange formed at a lower end thereof is fixed to a top plate of the refrigerator with a plurality of screws. In this case,
The thickness of the top plate is thin, and the mounting strength of the draft cannot be said to be sufficient. Therefore, there is a problem that the draft itself is shaky when operating the ejection lever. In addition, if used for many years, the screws may become loose and the draft may fall out of the refrigerator.

[0004] Further, since the screw for fixing the draft to the refrigerator is screwed from the outside of the flange toward the top plate, the screw head is exposed on the surface of the flange to deteriorate the appearance, and the projecting portion is formed. The garbage easily accumulates around the (head of screw) and becomes unsanitary. Furthermore, a drawback that cleaning properties are inferior due to the presence of the projecting portion is pointed out.

[0005]

8a is formed at a position corresponding to 8a,
Each horizontal portion 40 has a cutout portion 40a of a predetermined length.

An upper reinforcing plate (reinforcing material) 42 parallel to the lower reinforcing plate 36 is disposed and fixed by rivets or the like on the side (inner side) of the exterior plate 20 facing the interior plate 18. As shown in FIG. 5, the upper reinforcing plate 42 has a rectangular plate-shaped main body 41 having a long dimension in the front-rear direction, and is bent over the entire length of the main body 41 on both sides in the width direction (transverse direction). Hanging portions 43, 43 formed and hanging downward
The plate-shaped main body 41 has a through hole 41a formed at a position corresponding to the through hole 20a of the exterior plate 20.

Between the upper and lower reinforcing plates 36 and 42, a rectangular block-shaped reinforcing member 44 set to be substantially the same as the width of the plate-shaped main bodies 38 and 41 is disposed so as to be sandwiched therebetween. . As shown in FIG. 4, the reinforcing member 44 has cutouts 4 formed in the horizontal portions 40, 40 of the lower reinforcing plate 36.
0a, 40a, and in this state, the through holes 4 are located at positions corresponding to the through holes 38a, 41a of the upper and lower reinforcing plates 36, 42.
4a is drilled. That is, as shown in FIG. 1, the refrigerator compartment 24 and the outside of the refrigerator are connected to the through holes 14a, 20a, 41a,
The supply pipes 32 are inserted through the through-hole groups by communicating with each other through 44a, 38a, 18a. In addition, all the through holes 14
The inner diameters of a, 20a, 41a, 44a, 38a, 18a are set to be the same.

On the flange 28a of the draft 16,
A plurality of screw holes 28b opening downward are formed at positions facing the through holes 14a of the top plate 14, and each screw hole 28b has
The through holes 14a, 20a, 41a, 44a, 38a, 18a
The bolt 46 penetrated from the interior plate 18 side (refrigerator compartment 24 side) through is inserted. That is, a fixing bracket 48 is disposed on the inner surface of the interior plate 18 on the side of the refrigerator compartment 24, and a hole 48 formed in the bracket 48 is provided.
The bolt 46 is inserted from below into a, and its end is screwed into the screw hole 28 b of the draft 16.
Also, as shown in FIG.
A nut 50 is screwed between a and the fixing bracket 48, and the draft 16 is fixed to the housing 12 by rotating the nut 50 in a predetermined direction.
The fixing bracket 48 is also provided with a through hole 48b through which the supply pipe 32 can be inserted. Further, between the flange 28 a and the top plate 14, a through hole 14 of the top plate 14 is provided.
A packing 52 having a ring shape larger in diameter than a is inserted to prevent escape of cold air in the refrigerator compartment 24.

Here, depending on the manner of use at the customer site, for example, only three locations may be used without using all of the five draft attachment portions provided in the refrigerator 10. In this case, it is necessary to close the through-hole group in the two draft attachment parts that are not used, and in the embodiment,
The lower hole 54 and the upper hole 56 are used to close the through hole group.

As shown in FIG. 7, the lower cap 54 is formed by projecting a cylindrical portion 54b which can be inserted into a group of through holes on a disk 54a having an outer diameter which covers the through hole 18a of the interior plate 18. Then, the cylindrical portion 54b is fitted into the through hole group from below. A hole 54c is formed in the disc 54a at a position facing the plate-shaped main body 38 of the lower reinforcing plate 36, and a cylindrical portion 54a is formed.
In the state where the disc 54a is in contact with the inner surface of the interior plate 18 by inserting the b into the hole group, the fixing screw 58 inserted through the hole 54c is screwed into the screw hole 38b formed at the corresponding position of the lower reinforcing plate 36. Thus, the lower cap 54 is attached to the housing 12.

The upper cap 56 has basically the same structure as the lower cap 54, and can be inserted into a group of through-holes in a disk 56a having an outer diameter covering the through-holes 14a of the top plate 14. The tubular portion 56b is configured to protrude, and is detachably attached to the housing 12 by being fitted into the through-hole group from above. Note that the upper cap 56 is simply inserted into the through hole group of the cylindrical portion 56b, and is configured to be easily removable. As the material of the upper and lower caps 54 and 56, stainless steel, resin, or the like can be appropriately selected.

The length of the cylindrical portions 54b, 56b of the upper and lower caps 54, 56 is set so that the cylindrical portions 54b, 56b do not come into contact with the two caps 54, 56 attached to the housing 12. The heat conduction from the refrigerator compartment 24 to the exterior plate 20 side is eliminated to prevent the occurrence of dew. A heat insulator 58 having substantially the same height as the thickness of the housing 12 is disposed between the disks 54a and 56a of the upper and lower caps 54 and 56 in a state where the heat insulator 58 is inserted into the two tubular portions 54b and 56b. In addition, heat insulation at the draft attachment portion can be ensured.

[0019]

Next, the operation of the draft mounting structure according to the embodiment will be described. When assembling the housing 12 of the refrigerator 10, first, the lower reinforcing plate 36 is riveted to the interior plate 18 at each draft attachment portion so that the through holes 18a and 38a coincide with each other.
The upper reinforcing plate 42 is rivet-fixed so that the holes 20a and 41a coincide with each other. At this time, both reinforcing plates 36, 4
2 is positioned and fixed in parallel such that its longitudinal direction is aligned with the front-back direction of the housing 12. Upper and lower reinforcing plates 3
6, the notches 40a,
By positioning the reinforcing member 44 via the 40a, the spacing between the reinforcing plates 36 and 42 is fixed while holding the reinforcing member 44 therebetween. In this state, the space between the interior board 18 and the exterior board 20 is filled with the foamed heat insulating material 22 to obtain the housing 12 having a heat insulating structure. Also, on the upper surface of the exterior plate 20,
The top plate 14 is provided. Since the upper and lower reinforcing plates 36 and 42 are divided, a passage for the foamed heat insulating material 22 is secured between the two reinforcing plates 36 and 42, and the heat insulating material 22 is completely filled. Also, the lower reinforcing plate 36 to the upper reinforcing plate 4
Since there is no heat conduction to the outer case 2, the occurrence of dew on the exterior plate 20 can be suitably prevented.

The draft 16 is positioned at a position corresponding to the through hole 14 a of the top plate 14, and each hole 48 of a fixing bracket 48 disposed on the inner surface of the interior plate 18.
a into the housing 1 through the through hole group.
2 and is screwed into the corresponding screw hole 28b of the draft 16. Then, the nut 50 screwed between the head portion 46a of the bolt 46 and the fixing bracket 48 is rotated in a required direction, and the bolt 46 screwed into the draft 16 is moved downward, whereby the draft 16 is securely fixed to the housing 12. That is, the draft 16 is fixed to the housing 12 by the plurality of bolts 46 penetrating the housing 12 having a sufficient thickness dimension, so that the mounting strength of the draft 16 can be required and sufficient, and The draft itself does not fluctuate during the operation of.
Since the reinforcing member 44 is sandwiched between the interior plate 18 and the exterior plate 20, the spacing between the plates 18 and 20 changes due to excessive tightening of the bolt 46 and the nut 50, and the foam insulation 22 is compressed. There is no deformation.

The upper and lower reinforcing plates 36 and 42 extend in the operation direction of the pouring lever 34 in the draft 16 (the front-rear direction of the housing 12).
The strength of the casing side with respect to the above operation is improved, and the screw portion of the draft 16 does not loosen and shake even after long-term use. Further, since the bolts 46 for fixing the draft 16 to the housing 12 are screwed from the refrigerator compartment 24 side, the bolts 46 are not exposed on the outer surface of the draft 16 and the appearance is not deteriorated. In addition, since the bolt 46 does not travel to the outer surface, dust does not easily accumulate, cleaning can be easily performed, and hygiene can always be maintained.

If, for example, two of the five draft mounting portions provided on the refrigerator 10 are not used due to a change in the manner of use at the customer site, the draft mounting portion is not used. This is accomplished by closing the through-hole group in the portion with the upper and lower caps 54 and 56. That is, the lower cap 54 is attached by inserting the cylindrical portion 54b into the through hole group from the refrigerator compartment 24 side, and the disk 5a is fixed to the interior plate 18 via the plurality of fixing screws 58. Then, as shown in FIG.
In the state where the lower part of the heat insulating material 60 is inserted,
The upper cap 56 is inserted into the through-hole group from above the cylindrical portion 56b.
And insert. Since the heat insulating material 60 is interposed between the upper and lower caps 54 and 56, the refrigerator compartment 24 and the outside of the refrigerator are insulated from each other in an adiabatic manner, so that cold air leakage and dew can be prevented. In addition, since the upper and lower caps 54 and 56 are not in contact with each other, there is no heat conduction from the lower cap 54 on the refrigerator compartment 24 side to the upper cap 56 on the outside of the refrigerator, so that the exterior plate 20 can be prevented from being exposed. Further, since the upper cap 56 has few projecting portions, the cleaning performance is good and the design is also good. Further, since the upper and lower caps 54, 56 are easily attached and detached, it is possible to easily cope with a change in the number of drafts 16 to be used. When the upper and lower caps 54, 56 are attached to the draft attachment portion, a caulking agent may be applied between the outer peripheral edges of the disks 54a, 56a and the interior plate 18 or the top plate 14 in both the caps 54, 56. Recommended.

In the embodiment, the upper reinforcing plate is disposed between the exterior plate and the foam insulating material, and the lower reinforcing plate is disposed between the interior plate and the foam insulating material. However, both reinforcing plates are omitted. Then, a reinforcing member may be directly inserted between the interior board and the exterior board. It is also possible to omit one of the upper and lower reinforcing plates. Furthermore, you may make it fix a draft to a housing | casing only with a bolt.

[0024]

As described above, according to the draft mounting structure for a beverage dispenser according to the present invention, the reinforcing member is interposed between the interior plate and the exterior plate in a sandwiched state, so that the housing is attached to the housing. The draft can be securely and stably mounted. Further, since the bolts for fixing the draft to the housing are screwed in from the interior plate side, the bolts are not exposed on the outer surface of the draft, and the appearance does not deteriorate. Furthermore, since the bolts do not travel, it is difficult for garbage to collect,
Cleaning is easy and can be kept hygienic at all times. In addition, since the spacing between the interior board and the exterior board is held by the reinforcing member, by over-tightening the bolt,
Compressive deformation of the foam insulating material filled between the interior board and the exterior board is prevented.

Further, by providing a reinforcing plate extending between the reinforcing member and the interior plate or the outer plate in the operation direction of the pouring lever in the draft, the strength of the housing side with respect to the operation of the lever is improved. The draft does not loosen or fluctuate even after long-term use, and can be fixed stably for a long time.
