Description

[Detailed description of the invention] The present invention relates to a cooling box body that forms a cooling chamber in which a cooler and a blower are installed above a storage room. , the purpose is to improve the heat exchange of the air flow passing through the cooling chamber.

Hereinafter, an embodiment of the present invention will be explained with reference to the drawings. 1 shown in FIG. 1 has a main body composed of a heat insulating wall 2 which is made up of a front wall 2a, a top wall 2b, a back wall 2C and a bottom wall 2d and has an opening on the front side. A cooling box body such as a refrigerator or a refrigerated showcase, in which a cooler 3, a blower 4, and a fan case 5 are installed at the bottom of the top wall, and an air vent is installed at an appropriate interval from the inner walls of the top, back, and bottom walls. A cooling chamber 9 is constructed by arranging a saucer 6, a rear partition plate 7, and a bottom plate 8, respectively.
, a cold air passage 10 and a storage chamber 11 are formed, and an air outlet 12 and an inlet 13 facing each other are formed at the upper and lower ends of the opening, and the storage chamber 11 is cooled by a forced circulation cold air flow.

14 is a plurality of transparent door bodies that freely open and close the opening;
Reference numeral 15 denotes left and right side walls provided to cover both sides of the heat insulating wall.

As shown in FIG. 2, the cooler, fan case, and dew pan have defrosting heaters 16, 17, and 18 that are energized during defrosting.

Reference numeral 19 denotes a dogleg-shaped baffle plate provided at the lower corner of the air outlet side of the cooler; the upper end of this baffle plate is at an appropriate distance from the ceiling wall, and the lower end is close to the dew pan; Vessel 3
It guides the cold air flow flowing between the dew pan and the dew pan 6 to the bottom of the cooler, and increases the discharge pressure of the cold air flow that has undergone heat exchange in the cooler. This prevents the remaining water on the surface of the dew pan 6 from being blown out from the outlet 12 together with the cold air flow.

The dew pan also serves as the top plate of the storage chamber 11, and includes a locking portion 7a at the upper end of the partition plate and a bent portion formed on the wind direction plate 20 forming the air outlet and located higher than the locking portion. 20
The cooling chamber 9 and the storage chamber 11 are partitioned off by removably placing this dew pan on the container a, and the rear end is inclined low toward the air inlet side of the cooler to connect the drain port 6a to the upper part of the drain conduit 21. It is to be located in

This dew pan is composed of two metal plates 6b and 6b, a reinforcing material 6C interposed between the metal plates, and a defrosting heater 18. By lifting the protruding rear end upward and moving backward, it is placed on the locking part and the bending part as described above.

Incidentally, in the case of removal, it may be done in the reverse order.

Reference numeral 22 denotes a rectifier having a plurality of through holes 22a, which is attached to the front wall with a small distance 23 from the wind direction plate, and rectifies the flow of low-temperature, low-humidity cold air that has been heat exchanged in the cooling chamber arm. A predetermined air curtain is formed in the front opening.

The small gap is maintained at a speed faster than the cold air flowing through the through holes 22a, so that frost does not form on the wind direction plate 20 even if outside air enters when the door is opened. It is for.

24 is a shielding plate that covers the gap formed between the dew pan and both side walls when the dew pan is placed, and prevents cold air from leaking from the cooling chamber 9 to the storage chamber 11 through the gap. This is to maintain the cooling chamber at a predetermined pressure so as not to affect the speed of the air curtain, and to guide melted dew from the side wall 15 to the dew pan 6 during defrosting.

In this way, the present invention installs a cooler 3 at the bottom of the ceiling wall 2b of the heat insulating wall 2.
In a cooling box body 1 having a structure in which a blower 4 is installed, a baffle plate 19 is provided at the lower corner of the air outlet side of the cooler 3, and a removable dew pan 6 that slopes low is provided at the air inlet side of the cooler 3. Since the cooling chamber 9 and the storage chamber 11 are partitioned, the cold air flowing at the bottom of the cooling chamber 9 is guided to the lower surface of the cooler 3 by the baffle plate 19, increasing the air inlet area of the cooler. It is possible to heat-exchange all the cold airflow passing through the cooler with the condenser, increase this heat-exchanged cold airflow to a predetermined pressure, and obtain a predetermined speed to form an air curtain. By removing it, maintenance and inspection of the cooler 3, blower 4, etc. can be easily performed from inside the storage room 11.

As mentioned above, the main body is composed of an insulating wall with a front opening,
In the cooling box body in which a cooler and a blower are installed at the lower part of the top wall of the heat insulating wall, the blower is installed on the air inlet side of the cooler, and the lower corner of the air outlet side of the cooler is covered with the lower part of the air outlet side, and the air blower is installed below the cooler. A long baffle board is installed, and the top wall, back wall of the insulated wall, and
a removable dew pan that doubles as a top plate, located directly below the cooler, blower, and baffle plate at an appropriate distance from the inner wall of the bottom wall, and tilted low toward the air inlet side of the cooler while maintaining the distance from the cooler; It is characterized by the arrangement of a rear partition plate and a bottom plate to form a cooling chamber, a cold air passage, and a storage chamber, so that the baffle plate catches the residual water scattered at the bottom of the cooler and guides it to the dew catcher. At the same time, the cold air flowing at the bottom of the cooling chamber is guided from the bottom surface of the cooler to the cooler, increasing the air inlet area of the cooler to improve heat exchange of the cold air flowing through the cooling chamber, and improving the heat exchange of the cold air flowing through the cooling chamber. In addition to uniformly forming frost, it is possible to increase the heat-exchanged cold air flow to a predetermined pressure to form an air curtain, and by removing the dew pan, maintenance and inspection of coolers, blowers, etc. can be carried out from inside the storage room. It can be done easily.
