In all freezers and refrigerators all have integral plastic inner frame and the refrigerator door mezzanine both are filled with injection-type Styrofoam to keep cold. The plastic inner frames and Styrofoam are both environmentally unfriendly and difficult to recycle and wasteful a lot of energy.
Description
- This new model relates to field that injecting the Styrofoam into the plastic frame between the metal frames to make thermal insulation freezers and refrigerators.
- All freezers and refrigerators manufactured around the world have a metal shell with PVC plastic integrally injected into the five-sided inner frame and the refrigerator door inner space are filled with injection-type Styrofoam to keep cold. The plastic inner frame and foam plastic is both environmentally unfriendly and difficult to recycle.
- The innovative purpose of the new model is to use the metal frame interlayer of the refrigerator and the built-in vacuum airtight inner space of the refrigerator metal door. This innovation can eliminate the need to inject Styrofoam into the PVC plastic inner frame of the refrigerator for thermal insulation. It able to stainless steel fresh-keeping transportation inner and outer boxes and double-layer cover plates to replace the Styrofoam fresh-keeping cooler avoiding the environmental damage of Styrofoam which can't be recycled.

FIG. 1 is a schematic drawing of this invention applied to non-Styrofoam, non-Plastic inner frame of refrigerators. - A single-door refrigerator is shown in
FIG. 1 . Theouter door panel 10 and theinner door panel 102 of the refrigerator are air tightly welded with a 1 cm non-contact airtightinner space 101. The five-sided outer metal box frame 11 includes the back and the two sides on the left and right sides. There must be a 2 cm non-contact metalinner space 12 between the innermetal box frames 13. There are 5metal pipes 121˜125 specially designed to penetrate through the outer metal frame 11 and theinner metal frame 13 of the refrigerator with ten holes reserved on the panels. The purpose is to connect the compressor refrigerant refrigeration function outside the refrigerator with the refrigeration function inside the refrigerator. Note that themetal pipes 121˜125 must be shown inFIG. 1 , and the outer metal box frame 11 and the innermetal box frame 13 must be pre-installed on both ends of the plate. The remaining ten holes are air tightly welded on both sides to achieve ametal pipe 121 for the liquid refrigerant to pass through thecompressor 14 through theinner space 12 keep airtight to connect to thecondenser 15, and themetal pipe 122 for the refrigerant for gasification to pass through thecondenser 15. The airtightinner space 12 is connected to theradiator 16. Themetal pipe 123 is for gasification and pressurization of the refrigerant from theradiator 16 through the airtightinner space 12 and returns to thecompressor 14. Themetal pipe 124 is for the light source power line and thesensing thermostat 17 the pipelines are connected by the airtightinner space 12 in the refrigerator to the external frequency conversionpower control box 171 of the refrigerator. Themetal pipe 125 drains the dripping water from thecondenser 15 in the refrigerator through theinternal water canister 151 through the airtightinner space 12 to the refrigeratorouter evaporation tray 152. Note that when each metal pipe penetrates the space of the airtight inner of 12, the metal pipe body must non-contact the panel's surface of the outer metal box frame 11 and the wall surface of the innermetal box frame 13. The twoexhaust valves 20 are welded together separately to draw the airtight space into vacuum. The bottom of therefrigerator door 102 and the bottom of the inner metal box frame 11, the outer metal box frame 11 and the innermetal box frame 13 should be air-tightly welded around thefront 126 position to form 12 with 2 cm that does non-touch the airtight space, and then the door frame rubber bead 103, which is exactly the same size as the refrigerator door, is placed at a predetermined position around theinner door 102 of the refrigerator. Finally, thetop metal cover 18 of theradiator 16 is fixed at the predetermined position on the upper part of the outer metal box frame 11. The above all-metal products used the vacuum insulation and a cold insulation vertical single-door refrigerator is completed. Multiple metal partition spaces are able built in themetal box 13 of the same refrigerator, and the multi-temperature zone vertical multi-door refrigerator and freezer can be designed and made with no more have PVC plastic inner frame and no-environmentally hazardous Styrofoam. -
