Description

[Detailed Description of the Invention] The present invention relates to a heat source device used in cold storage or hot storage cases for storing and displaying beverage cans, and its purpose is to efficiently and uniformly heat or cool beverage cans.

Generally, as shown in Fig. 1, a refrigerated storage case has a machine room 4 containing a compressor 1, a pseudo-condenser 2, an evaporator 3, etc., a storage/display room 5 whose four sides are made of transparent double-glazed glass, and 5 and a shelf 7 for heating the beverage cans 6 placed thereon. When heating the beverage cans 6, the shelves 7 are used to heat them, and the fan 8 in the machine room 4 is rotated to circulate hot air in the storage display room 5 as shown by the arrow. In addition, beverage cans 6
When cooling, the above-mentioned cooling device in the machine room 4 is driven, and the fan 8 circulates cold air into the storage and display room 5 as shown by the arrow. Note that 9 is a transparent door for taking out the beverage can 6.

In such a refrigerated storage case, the conventional shelf 7 for heating the beverage cans 6 has a flat top surface as shown in FIG. Since it is formed tightly and equally, generally a recess 6c is formed on the upper and lower surfaces, and as a result, it is in a state close to line contact with the beverage can 6. Therefore, the heating efficiency of the shelf 7 is poor, and the heating temperature is lower and the temperature rise is slower at the outer periphery of the storage/display room 5, where heat radiation is greater at the border with the outside air, and uneven heating is likely to occur. In addition, since the beverage cans 6 are arranged according to the sense of the person displaying them, the intervals between the cans tend to be irregular, which not only improves the display effect but also hinders the action of hot or cold air. So it was warm.

The present invention provides a large number of protrusions on the top surface of the shelf that are in close contact with the bottom of the can and have larger diameters on the outer periphery.
This eliminates the drawbacks of the above conventional example.

An embodiment of the present invention will be described below with reference to the drawings. Parts that are the same as those in FIGS. 1 and 2 will be given the same reference numbers and explanations will be omitted, and only the different points will be explained.

10 is a heat conductive shelf installed in the storage display room 5;
On the back side there is a surface heater 11 and an automatic temperature controller 12.
is installed. On the upper surface of the shelf 10, a large number of convex portions 13 are formed which are regularly arranged vertically and horizontally, are in close contact with the bottom surfaces of the beverage cans 6 (also referred to as the upper and lower lids 6a), and have a larger diameter toward the outer periphery of the shelf. are doing. 14 is a flange formed on the outer periphery of the shelf 10;
Reference numeral 5 designates a guide plate having a large number of guide holes 15a having the same size and having the same center as each convex portion 13. The outer periphery of the plate 5 is placed in contact with the flange 14, and the beverage can 6 is placed on the shelf 10 through the guide hole 15a. By fitting, lateral displacement of the convex portion 13 with a small diameter is prevented. 16 is a heat insulating material for the surface heater 11; 17
This is a case in which the heat insulating material 16, the surface heater 11, and the shelf 10 are placed in this order and integrated.

In the above embodiment, the beverage can 6 is inserted into the guide hole 15.
When the can is placed on the shelf 10 according to the position a, the bottom 6a of the can is brought into close contact with the convex portion 13. Heat is transmitted to the beverage can 6 through surface contact with the convex portion 13, and the beverage can 6 is heated, and the can nearer to the outer periphery is heated by the convex portion 13 having a larger diameter. Moreover, since the beverage cans 6 are placed on the convex portion 13, they are arranged regularly and the distance between the cans is p.
can also be kept approximately constant.

Furthermore, since the diameter of the convex portion 13 is smaller as the beverage cans 6 are located closer to the center on the shelf 10, lateral displacement is more likely to occur within the range of the concave portion 6c. Keep the distance between each other constant.

Note that it is also possible to cool the beverage cans 6 by disposing a cooling pipe of a refrigeration cycle on the back surface of the shelf 10.

As described above, the present invention forms a number of convex portions in close contact with the bottom surface of the beverage cans on the upper surface of the shelf that is installed in the storage display room and heats or cools the beverage cans placed thereon.
Since this convex part has a larger diameter as it approaches the outer periphery of the shelf, heat can be transferred through surface contact of the convex part to the can bottom, making it possible to heat or cool beverage cans more efficiently than before, and also to store and display them. Beverage cans can be heated and cooled almost uniformly regardless of the inner and outer circumferences of the chamber.

Furthermore, by arranging a large number of convex portions in a regular manner, the convex portions can be used to arrange the beverage cans in an orderly manner to enhance the display effect, and the intervals between the beverage cans can be kept approximately constant, allowing the storage and display space to be kept constant. In the case of heating by circulating cold air or hot air, the cold air or hot air can be distributed over substantially the entire beverage can.
