Description

  The present invention relates to an environmentally friendly electronic refrigerator having good heat exchange efficiency without a cooling fan that causes noise and failure.

  Conventional electronic refrigerators include those that use chlorofluorocarbon or alternative chlorofluorocarbon as the radiator and those that use the fan motor as the aluminum radiator. In particular, hospitals and hotels are demanding products that do not use CFCs and environmentally friendly products that are free from fan noise and malfunction.

  There was no product that was completely harmless and cost-effective during disposal without using alternative chlorofluorocarbon gas in the heat dissipation unit.

  Traditionally, fan motors have been used to dissipate heat pipes, but they suffer from noise and troubles and maintenance.

  Since the Peltier module is used for cooling, the heat absorbing part is attached in close contact with an aluminum plate disposed in the cabinet, and the interior is cooled without the need for a fan.

  A heat pipe heat dissipating unit composed of a copper heat pipe and aluminum fins is attached to the heat generating part on the rear side of the outside of the cabinet to radiate heat by air convection in the room.

  The heat pipe heat dissipation unit uses a plurality of copper heat pipes in which a small amount of pure water is vacuum-sealed. As a result, since the pure water refrigerant in the copper tube heated by the Peltier module heat generating section becomes water vapor and is efficiently transferred by heat, a plurality of aluminum fins penetrated through several aluminum fins arranged at equal intervals Dissipates heat from the copper pipe.

  To open and close the door, place several magnets symmetrically on the entrance side and inside the door, attach packing to the recess inside the door, and attach the door to the projection formed on the entrance side I can do it.

  The guide rails arranged symmetrically on the left and right wall surfaces in the cabinet and the guide rails on the basket, which are arranged opposite to the inside of the door, are automatically moved to the interior of the cabinet by the inclined parts and pulleys. Because it has a function to be pulled into the refrigerator, the refrigerator main body and the door are completely in close contact to prevent forgetting to close.

  From the viewpoint of hygiene and safety, antibacterial agents are added to the parts (plastics) and molded to suppress the generation of mold, fungi, and odors.

  As described above, the electronic refrigerator is environmentally friendly, safe, harmless, excellent in hygiene, and does not adversely affect the environment as compared with a refrigerator that uses a conventional heat exchanger using CFC gas and a fan motor. Since there is no noise or malfunction and maintenance costs are reduced, demand from hospitals and hotels is expected.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  In FIG. 1, 1 is a heat pipe heat dissipation unit and 2 is a Peltier module. A plurality of copper heat pipes 3 are used, and 5 is a copper tube sealing portion in which a small amount of pure water is vacuum-sealed. 4 is an aluminum fin part, and 4a and b aluminum fins are arranged on the left and right sides of 3 respectively.

  FIG. 2 is a view of 1 as viewed from the side, and 3 passes through two copper tube holding holes 6. Reference numeral 7 denotes a heat radiating hole. 8 is a heat pipe heat radiating unit mounting portion, and 1 is screwed to the rear surface outside the cabinet.

  3 of FIG. 3 is a refrigerator main body, 10 is in a store | warehouse | chamber, 11 is an in-store installation aluminum plate, closely_contact | adheres to 2 heat absorption parts, and 10 is cooled. 12 is a guide rail with a pulley, and it is symmetrically arranged on the side surface of 10. There are 13 guide rail slopes at the back of the inner side surface of 12 and has a function of automatically retracting 14 doors. Reference numeral 15 denotes a handle with a door protruding pin, and the four close contact surfaces of the 19 inner magnets and the close contact surface 4 of the 20 door side magnets are symmetrically arranged. Pulling on each other leaves the close contact surfaces. The 16 door handles serve to pull out 25 baskets. Since the 17 door inner concave portion has packing, when the 18 inner inlet convex portions are combined, a state without a gap is maintained.

  In FIG. 4, screws 12 are symmetrically screwed to the side surfaces of 10. Reference numeral 13 denotes an inclined portion.

  In FIG. 5, 22 guide rails with pulleys are made in a frame shape so that 25 can be placed thereon. Attach the left and right sides of 14 warehouses symmetrically. The guide rail door side inclined portion of 23 is located at the entrance to the inside of the cabinet, and 13 is located at the back of the inside of the cabinet, so that 25 is contained in 10.
