Description

[Detailed Description of the Invention] The present invention relates to an improved configuration of a liquid cooling device, and in particular, the top opening of a cooling container is covered so as to be openable and closable.

Conventionally, in this kind of liquid cooling device, as shown in Fig. 1, the upper opening of the cooling container A is closed with a cover plate B, but the sealing member C is fitted onto the periphery of the opening of the cooling container A cover plate was placed on it. Therefore,
There is a gap between the inner circumferential surface of the rising edge (E) forming the stepped portion (D) of the seal member (C) and the outer circumferential surface of the lid plate (B), and the airtightness of the cooling container (A) is poor, and the lid plate (B) may be damaged due to shock vibrations, etc. This was inconvenient because it easily moved or floated up. In addition, since the outer circumferential surface of the rising side E of the step part D is formed to be inclined with the lower part facing outward, the contact part with the upper surface plate of the exterior body is engaged in the middle of the outer circumferential surface of the rising side E. Since the seal member is stopped and rarely comes into contact with the outer horizontal side of the seal member, the stability is poor, and the gap between the top plate and the rising side becomes large, making it easy for dust etc. to get clogged, which is bad for aesthetics and hygiene. I didn't like it.
For this reason, it is possible to make the gap as small as possible to bring the periphery of the lid plate B and the rising edge E into close contact, but this time, air will not be replenished into the cooling container A, and the liquid will not be dispensed from the liquid supply pipe. There was a fear that it would get worse. In particular, place items such as pots on the lid plate,
If the so-called lid plate B is pressed, the lid plate B will be pressed onto the stepped portion of the seal member C and will come into close contact with it, resulting in poor air supply into the cooling container A, which will prevent the beverage liquid from being poured. There were times when I couldn't go out smoothly.

This proposal was made in consideration of these points, and the figures will be explained below.

Reference numeral 1 denotes an exterior body with a base 2 at the bottom, and a vertically elongated equipment chamber 3 is formed at the rear of the exterior body, extending both upward and downward. 4 is a compressor fixed on the base 2 at the lower part of the equipment room 3; 5 is a condenser fixed approximately horizontally at a suitable position in the equipment room 3; 6 is a dryer; 7 and 8 are first and second The solenoid valves 9 and 10 are first and second capillary tubes, and these components constitute a refrigerant cycle. Reference numeral 11 denotes a blower disposed directly above the condenser 5, which draws air into the equipment room 3 through the intake hole 12 on the lower side wall of the exterior body 1 and discharges it from the exhaust hole 13 on the top plate portion 1a. The condenser 5 etc. are forcibly cooled.

Reference numerals 14 and 15 denote a pair of first and second cooling containers that are located in front of the upper half of the equipment room 3 and installed in parallel inside the exterior body 1. Both cooling containers 14 and 15 are made of stainless steel plates, respectively. The sealing members 31 and 32 are formed into a cylindrical shape with a bottom and an upper opening, and the upper part of the sealing members 31 and 32 are fitted into the outward facing flange at the upper end and come into contact with the opening edge of the upper plate portion 1a of the exterior body 1. It is supported and the lower part is fixed by a U-shaped support fitting 16. 17, 18 are cooling containers 14,
The first and second coolers are respectively wound around the outer peripheral surface of the refrigerant 15 in a heat exchange relationship, and are constituent parts of the refrigerant cycle. Reference numerals 19 and 20 denote first and second liquid supply pipes that are attached to the bottoms of the cooling containers 14 and 15 and discharge the stored liquid, respectively, and are made of a soft elastic member such as silicone rubber. 21 and 22 are levers 23 and 24
The first and second liquid supply valves 25 and 26 open and close the middle of the liquid supply pipes 19 and 20, respectively. A second thermostat 27 is formed of styrofoam or the like and is connected to the cooling container 1.
This is a heat insulating material that surrounds both 4 and 15.

Denoted at 28 and 29 are removable lids that are attached to the upper openings of the cooling containers 14 and 15, and are made of synthetic resin or metal plates. Reference numeral 30 denotes an inner lid that floats above the liquid level of the wine or the like in the first cooling container 14, and this inner lid 30 is made by punching out a resin sheet such as polypropylene or polyethylene, which has a lighter specific gravity than the wine or the like. It is formed into a disk shape with an outer diameter slightly smaller than the inner diameter. A similar inner lid is also provided on the second cooling container 15.

The sealing member 31 is made of an elastic member such as rubber or synthetic resin, and is formed to have a substantially convex cross section with a base 33 and a raised portion 34 rising upward from a proper central position of the base 33. Cooling container 14
An engagement groove 35 is formed in which the outward flange 14A of the opening periphery fits. Further, the rising part 34 has an inner circumferential surface sloped so that the upper end is located inward and the joint with the base part 33 is located outward, forming an inclined surface 34A at an angle that provides a small distance from the cover plate 28. body 1
The outer circumferential surface on which the circumferential surface of the hanging side 1b of the upper surface plate portion 1a abuts is connected to the base portion 33 as a substantially vertical surface 34B. In addition, this rising part 34 is formed such that the inner diameter of the upper end of the inclined surface 34A is slightly smaller than the outer diameter of the cover plate 28 placed on the base 33, and the inner diameter of the lower end of the inclined surface 34A, which is the joint part with the base 33, is made smaller than the outer diameter of the cover plate 28 placed on the base 33. It is formed larger than the outer diameter of the plate 28. Further, the base 33 has a thin flexible fin that is in close contact with the upper surface of the outward flange 14A of the cooling container 14 above the engagement groove 35 and in contact with the outer surface of the outward flange 14A of the cooling container 14 in the lower part. A piece 38 is formed. The other seal member 32 also has the same configuration as this one seal member 31. The lid plates 28 and 29 have a concave central portion to form a substantially dish-like shape. Further, the sealing member 31 is applied to the inner circumferential edge step 37 on which the downwardly hanging edge 28A formed on the periphery of the lid plate 28 rests, from the vicinity of the rising portion 34 outward from the abutting position of the hanging edge 28A. Extending inward from the abutting position of the hanging edge 28A, one groove 38 or, as in the embodiment, a plurality of grooves 38 are formed.

The other seal member 32 also has the same configuration as this one seal member 31. With this configuration, beverages with different cooling temperatures, such as red wine and white wine, are injected into one cooling container 14 and the other cooling container 15, and the compressor 4 is operated to supply refrigerant to the refrigeration cycle. The cooling vessels 14 and 15 are cooled by circulation in both coolers 17 and 18, respectively. Although the present invention has been described as having two cooling containers 14 and 15, the same effect can be obtained even if only one cooling container 14 is used.

Since the present invention is constructed as described above, even if the lid plate is pressed against the stepped inner circumferential edge of the sealing member, such as when an item such as a pot is placed on the lid plate after the cooling container is closed, the lid plate will not be damaged. Communication between the inside and outside of the cooling container is always ensured by the groove formed across the inside and outside of the contact position, and the inside of the cooling container never becomes negative pressure, air is replenished, and the beverage liquid is poured out. can be performed smoothly. Therefore, the lid plate and the inner circumferential edge step portion of the seal member can be molded in close contact with each other, and the intrusion of dust can be effectively prevented.
Moreover, the groove can be formed during molding of the seal member, and almost no additional work is required.
