Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a brine tank of a frozen dessert supply apparatus, and more particularly to an apparatus for preventing frost formation on the back of a lid of a brine tank.
[0002]
[Prior art]
The overall structure of the frozen dessert supply apparatus is shown in FIG. While the cooler 2 and the internal fan 3 are disposed on the ceiling portion in the freezer compartment 1, the refrigerator 5 connected to the cooler 2 is disposed in the machine chamber 4. The internal air sucked through the duct 6 provided in the inner surface of the freezer compartment 1 is cooled by the cooler 2 and is circulated and supplied into the freezer compartment 1 by the internal fan 3. It is maintained at such a temperature that iced confections such as ice cream can be poured out.
[0003]
When the cock 7 is opened, the valve body 8 is raised, the communication port 9 is opened, the dispensing switch 10 is turned on, and the pump 11 in the machine chamber 4 is driven in the forward direction, as indicated by a solid arrow. Further, the brine 13 is supplied from the brine tank 12 to the pressure chamber 15 below the dispensing cylinder 14. As a result, the piston 16 rises and the pack 17 accommodated in the upper part of the extraction cylinder 14 is compressed, and the frozen dessert 19 flows out from the outlet 18 of the pack 17 and passes through the communication port 9 and is discharged from the outlet 20. . When the cock 7 is closed, the dispensing switch 10 is turned off, the pump 11 is stopped, the valve body 8 is lowered, the communication port 9 is closed, and the extraction of the frozen dessert 19 is stopped.
When all the frozen desserts 19 in the pack 17 are poured out, the pump 11 is driven in the reverse direction by the operation of the operation panel 21, and the brine 13 is moved from the pressure chamber 15 of the pouring cylinder 14 to the brine tank as indicated by the broken arrow. Returning to 12, the piston 16 descends. In this state, the lid 22 of the dispensing cylinder 14 is opened and the pack 17 is replaced.
[0004]
[Problems to be solved by the invention]
However, since the pump 11 in the machine room 4 and the brine tank 12 in the freezer room 1 are connected to each other by the pipe 23, the temperature from the machine room 4 or the heat from the pump 11 generated when the frozen dessert is poured out through the pipe 23. Is transmitted to the brine 13 in the brine tank 12. For this reason, a difference inevitably occurs between the internal temperature of the freezer compartment 1 and the temperature of the brine 13 in the brine tank 12, and the water that dilutes the brine 13 slightly evaporates due to this temperature difference. The evaporated water rises in the brine tank 12 and comes into contact with the back of the lid of the brine tank 12 which is substantially equal to the internal temperature to form frost. For example, when the frozen confection 19 is left in a cooling operation state for a long time without pouring out the frozen dessert 19, the frost grows and its layer thickness increases.
[0005]
When the layer frosted on the back of the lid of the brine tank 12 becomes thick in this way, the amount of the brine 13 in the brine tank 12 gradually decreases. As the amount of the brine 13 in the brine tank 12 decreases, the heat conduction from the machine room 4 becomes more intense, and the difference between the temperature in the freezer compartment 1 and the temperature of the brine 13 in the brine tank 12 increases. As a result, there is a fear that an error display blinking and a warning may be issued to notify a shortage of brine by detection of a float switch provided in the brine tank 12.
The present invention has been made to solve such problems, and an object thereof is to provide a brine tank of a frozen dessert supply apparatus capable of preventing frost formation on the back of the lid.
[0006]

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 shows a cross section of a brine tank of a frozen dessert supply apparatus according to an embodiment of the present invention. The brine tank has a tank body 31 with an open top and a lid 32 that covers the top of the tank body 31, and a frosting prevention member 33 is disposed between the tank body 31 and the lid 32. . As shown in FIGS. 2 and 3, the frost prevention member 33 includes a top plate 34 that covers the upper portion of the tank body 31, and a plurality of hanging plates 35 that are fixed to the lower surface of the top plate 34. . As shown in FIG. 1, when the frost prevention member 33 is disposed on the upper portion of the tank body 31, the size of each hanging plate 35 is such that the lower end portion of the hanging plate 35 is positioned near the bottom surface of the tank body 31. Is set. If the top plate 34 can cover the upper portion of the tank body 31, the lower end portion of the hanging plate 35 may contact the bottom surface of the tank body 31.
Both the top plate 34 and the plurality of hanging plates 35 of the anti-frosting member 33 are made of a material excellent in heat conduction, for example, copper. Further, a heat insulating material 36 is attached to the upper surface of the top plate 34, and a lid 32 is disposed on the heat insulating material 36.
[0008]
As shown in FIG. 1, the brine tank is formed by placing the frost prevention member 33 and the heat insulating material 36 on the tank body 31 and placing the lid 32 on the heat insulating material 36 and fastening them together. .
In FIG. 1, the drooping plate 35 at the left end of the frost prevention member 33 is disposed at right angles to the other drooping plates 35, and this drooping plate 35 allows a discharge pipe provided in the tank body 31 to escape. A notch 37 is formed.
