[Prior art]

This type of heat exchange device is equipped with a compressor, a condenser, a blower fan, etc. along with the above-mentioned heat exchange tank.
There are many ways to arrange each of these parts within a case.

[Problem that the invention attempts to solve]

By the way, one method of compactly arranging each of the above-mentioned parts in one case is to divide the inside of the case into upper and lower halves by a plate extending horizontally, and place the compressor, condenser, One possible method is to arrange a blower fan and a heat exchange tank above the plate. If such an arrangement is adopted, the lower side of the plate functions as a wind tunnel, so the wind generated by the blower fan is extremely effectively supplied to the compressor and condenser, and the heat exchanger is accommodated in the heat exchange tank. It is extremely easy to take out.

An object of the present invention is to provide a heat exchanger in which various parts are arranged in the case as described above, and to support and fix the plate arranged in the case by extremely easy means.

[Means for solving problems]

In the present invention, a plate that stands up on at least one pair of legs and extends horizontally is used as the plate in the heat exchange device described above, and the heat exchange tank is supported on the plate at its bottom. It is characterized in that the upper opening edge is fixed to the upper opening edge of the case body, and the plate is held between the heat exchange tank and the base of the case.

[Functions and effects of the idea]

In such a configuration, if both legs of the plate are fitted into predetermined parts of the base and erected, the plate is held between the heat exchange tank and the base, so it is firmly supported and fixed by both. . Therefore, the plate can be assembled into the case by simply fitting both legs of the plate into predetermined parts of the base, and the plate can be assembled very easily and in a short time.

and the base 31 of the case 30.

In order to produce ice cream using this freezing device, first, the drain hose 11d is fitted into the holder 35 as shown in FIG. A container 12 filled with ice cream batter is placed in the cooling tank 11. Next, the small diameter gear 22 of the drive mechanism 20 is fitted and assembled to the adapter 21b of the motor 21, and the large diameter gear 22 is assembled.
The protrusion 13e of the impeller 13 is inserted into the recess 23a of 3.
The impeller 13 is fitted to the large-diameter gear 23, and the impeller 13 in this state is erected in the container 12. The impeller 13 has its rotating shaft 13a

When the lid 33 is fitted to the upper peripheral edge of the refrigeration system 2, the refrigeration system is set to the state shown in FIGS. 1 and 2.

In such a state, if the switch of the drive circuit (not shown) of the refrigeration system is closed and electricity is supplied for a predetermined period of time, the compressor 14, condenser 15, and cooling fan 17 will be activated.
etc., and the cooling medium flows through the pipe line 17b shown in FIG.
→ 17a → 17d are refluxed to cool the cooling tank 11, while the motor 21 in the drive mechanism 20 is started to rotate the impeller 13 and stir the ice cream batter. As cooling progresses in the cooling tank 11, the water present in the circumferential space between the cooling tank 11 and the container 12 freezes, causing both of them to cool.
1 and 12 are joined and integrated with the minimum ice pressure, and the container 12 is prevented from rotating while maintaining heat conduction between both 11 and 12. In addition, the container 12
Inside, the ice cream dough is frozen on the inner periphery 12b and gradually grows, and this frozen material is sequentially scraped off by the impeller 13. After a predetermined period of time has elapsed and the process shifts to ice cream, the supply of power to the refrigeration system is stopped, and the compressor 14, cooling fan 17, motor 21, etc. stop driving.
Therefore, by removing the lid 33 and taking out the impeller 13 together with the large-diameter gear 23 from the container 12, the ice cream can be easily taken out. In addition, in order to discharge the water in the cooling tank 11, the discharge hose 11d is removed from the holder 35 and directed downward. As a result, water in the cooling tank 11 passes through the through hole 11d and the drain channel 11c to the drain hose 11.
It is discharged from d.

In addition. To produce ice using the freezing equipment,
This is done by housing a cylindrical ice holding frame in the cooling tank 11, replacing the impeller 13 with an impeller for producing ice, and injecting a predetermined amount of water into the cooling tank 11.

By the way, in a refrigeration system with such a configuration,
Since the partition wall member 34 is held between the base 31 of the case 30 and the cooling tank 11, the lower ends of both legs 34b and 34c of the partition wall member 34 are simply fitted into predetermined positions of the base 31 as in this embodiment. The partition wall member 34 is firmly supported and fixed within the case 30. Therefore, with this configuration, the work of assembling the partition wall member 34 can be done easily and in a short time.
