As shown in FIG. 2, a cooling chamber 5 for storing products surrounded by a heat insulating material 4 and a machine chamber 6 provided below the cooling chamber 5 are formed inside the cooling chamber 5, as shown in FIG. This cooling chamber 5 is formed by an inner box 8 having an opening 7 for loading and unloading products in the front half of the upper surface, and a refrigerant flow pipe 9 is disposed around the inner box 8. 8
A cooler for cooling the inside of the cooling chamber 5 is constituted by the coolant flow pipe 9 and the coolant flow pipe 9. Further, an opening 10 for loading and unloading products is formed in the front half of the upper surface of the main body 1, and this opening 10 is releasably closed by the glass door 3. That is, a pair of guide rails 11 are provided at the upper part of the main body 1, and the glass door 3 is guided by the guide rails 11 from the closed position where the opening 10 is closed, as shown in FIG. It can be moved to an open position where the part 10 is opened. in this case,
The guide rail 11 is installed in an inclined state so that the back side is higher, and the glass door 3 is always held in the closed position by its own weight. Further, the front glass 2 is formed of double glass, and has upper and lower decorative frames 12.
a, 12b. A support portion 13 for supporting one end of the guide rail 11 extends inside the main body 1 from the upper decorative frame 12a, and heaters 14, 14 for preventing the glass door 3 from freezing are provided in the support portion 13. is attached. Furthermore, a table board 1 is provided on the rear half of the top surface of the main body 1.

In addition, 19 is a heater for freezing prevention buried in the front end part of the upper insulating material 4a which covers the upper half part of the cooling chamber 5.

By the way, in the case of the conventional structure described above, the cooling chamber 5 was closed by the glass door 3, so for example, as at the time of sale, the glass door 3
Even when the cooling chamber 5 is opened and closed frequently, the cooling performance is maintained to the extent that the products in the cooling chamber 5 can be sufficiently cooled. Furthermore, even if the cooling room 5 is closed for a long time by the glass door 3, such as at night or other times, there is a risk that the cold air in the cooling room 5 will leak to the outside through the glass door 3. Therefore, it was necessary to cool the inside of the cooling chamber 5 with the same cooling performance as that at the time of sale even at times other than the time of sale, resulting in poor cooling efficiency and a problem in reducing the amount of electricity used. Therefore, in cases other than sales, by covering the outer surfaces of the glass door 3 and front glass 2 of the main body 1 with a night cover 18 that is separate from the main body 1, the cold inside the cooling chamber 5 can be aired outside. Efforts are being made to improve cooling efficiency and reduce electricity consumption by preventing leakage. However, in this case, it is necessary to prepare a separate storage place for the night cover 18, and the operation of attaching and detaching the night cover 18 is troublesome, and there is also the disadvantage that it tends to be unsanitary. In addition, external heat easily leaks into the main body 1 through the front glass 2, table board 15, etc., and heat is constantly supplied to the main body 1 by the heaters 14, 14, so cooling This was a problem in trying to improve the cooling efficiency in the room 5.

This invention was made in consideration of the above circumstances, and its purpose is to provide a show case that can improve the cooling efficiency in the cooling chamber, reduce the amount of electricity used, and is easy to operate.

It is locked to. This curtain cover 30 is formed in a substantially U-shape, and has an engagement recess 32 that opens downward at the top, and a locking protrusion 33 that extends downward at the bottom. has been done. Furthermore, a first drain outlet 34 is provided at the bottom of the curtain cover 30. On the other hand, the lower decorative frame 12b includes a first frame 35 disposed in front of the main body 1, a second frame 36 covering the upper end surface of the heat insulating material 4, and this second frame 3.
It is formed from a plurality of spacers 37 disposed on 6. A recess 38 with a lowered intermediate portion is formed in the second frame 36, and a second drain outlet 39 is provided at the lowest part of the recess 38. Drain discharged from this second drain outlet 39 is discharged to the outside via a drain pipe 40 buried within the heat insulating material 4. Each of the spacers 37 is arranged on this recess 38,

Reference numeral 43 denotes a door sealing member affixed to the back surface of the glass door 3 in a downwardly protruding state so that the opening 7 of the cooling chamber 5 is opened and the opening of the main body 1 is sealed by the glass door 3. When the portion 10 is closed, the lower end of the seal member 43 engages with the upper edge of the curtain cover 30 to prevent cold air from leaking between the glass door 3 and the curtain cover 30. ing.

Therefore, in the case of the above-mentioned structure, when products are frequently taken out from the cooling chamber 5, such as during sales, the curtain 22 is stored in the curtain storage section 21 as shown in FIG. The opening 7 of the cooling chamber 5 is held open, and the glass door 3 is opened and closed to take out the products in the cooling chamber 5. In addition, when the glass door 3 is kept closed for a long period of time, such as at times other than sales at night, the curtain 22 is connected to the insulating frame 23 and the lower decorative frame 12b as shown in FIGS. 3 and 6. The opening 7 of the cooling chamber 5 is closed by the curtain 22. In this way, leakage of cold air from the cooling chamber 5 can be doubly prevented by the curtain 22 and the glass door 3, and the volume of the cooling chamber is reduced. Cooling efficiency can be significantly improved and electricity consumption can be reduced. Furthermore, by closing the opening 7 of the cooling chamber 5 with the curtain 22, the heaters 14, 14
Since the heat from the heaters 19, 19 is supplied into the cooling chamber 5 and is also prevented, the cooling efficiency within the cooling chamber 5 can be further improved. Further, the curtain 22 is stored within the main body 1,
Unlike night covers, there is no need to prepare a separate storage area, and there is no risk of unsanitary conditions. moreover,
Since the curtain 22 can be put in and taken out by moving the curtain cover 30, the opening 7 can be easily opened and closed. In addition, if dew condensation occurs on the curtain 22 when the curtain 22 is used, the condensate that has adhered to the curtain 22 is transferred from the first drain outlet 34 of the curtain cover 30 to the condensate that has adhered to the recess 38 of the second frame 36. The water is also collected in the recess 38 of the second frame 36 and discharged from the second drain outlet 39 to the outside via the drain pipe 40. Therefore, curtain 2
The drain adhering to the curtain 2 does not fall into the cooling chamber 5 when the curtain 22 is stored, so that the products in the cooling chamber 5 are not wetted, and the front glass 2 is not difficult to see.

Further, the curtain 22 is not only used at times other than sales, such as at night, but can also be used, for example, when it is desired to quickly cool the products in the cooling chamber 5 to a predetermined cooling temperature.

Note that this invention is not limited to the above embodiments. For example, the curtain storage section 21 is formed in the second frame body 36 of the lower decorative frame 12b, and when the curtain 22 is used, the curtain cover 30 is attached to the insulating frame 2.
It may be configured such that it is locked in the third position. Further, the locking portions 29 and 31 that lock the support rod 28 may be attached to the lower frame body 25 and the curtain cover 30 using hook-shaped locking tools or the like using screws or the like. Further, the curtain 22 may be made of waterproof cloth or rubber, and the shape of the curtain 22 may be a bellows shape or a folded shape.

As explained above, according to this invention, a curtain that closes the opening of the cooling chamber is provided inside the opening and closing door that closes the opening of the main body, so that when the curtain is closed together with the opening and closing door, the cooling chamber is The curtain and the opening/closing door can double prevent cold air from leaking to the outside. Therefore, the cooling efficiency in the cooling chamber can be significantly increased, and the amount of electricity used can be reduced.
