Definitions

  • This invention extends to an electric refrigerator and more particularly relates to the air duct system of an electric refrigerator.
  • Electric refrigerators particularly domestic electric refrigerators using a blown air cooling system
  • This air duct system includes an air duct cover plate mounted on the rear heat insulating wall of the cold storage room or freezer room, an evaporator mounted in the space between the air duct cover plate and the heat insulating wall, and a fan attached to the upper or lower end of the evaporator.
  • US patent application US2006 / 0070395 A1 discloses a conventional electric refrigerator with an air duct system.
  • the fan In the air duct system of this refrigerator, the fan is arranged vertically above the evaporator. Due to the rather large volume of the fan, the motor part of the fan is embedded in the heat insulating wall, which reduces the thickness of the heat insulating layer at this point, which adversely affects keeping the temperature of the cold storage room in the refrigerator.
  • US patent application US2007 / 0157646 A1 discloses another improved electric refrigerator with an air duct system. The fan in the air duct system of this refrigerator has been modified so that it is horizontal above the Evaporator is attached. In this way, the disadvantage of the fan in US2006 / 0070395 A1 has been overcome.
  • the object of this invention is to provide an electric refrigerator having an air duct system with which energy efficiency can be increased.
  • an electric refrigerator of one embodiment of this invention comprises a cabinet body having an internal receiving space, a door movably connected to the cabinet body for closing this internal receiving space, and an air duct system mounted on the heat insulating rear wall of the cabinet body, said air duct system including an air duct cover plate Air outlet openings, one mounted between Luftkanalabdeckplatte and heat insulation rear wall mounted evaporator and a fan.
  • the fan is mounted horizontally above the evaporator.
  • the air outlet openings on the Lucaskanalabdeckplatte are mounted obliquely. The airflow caused by the fan will blow upwards or downwards into the inner receiving space at an angle oblique to the air duct cover plate.
  • the described internal receiving space is the refrigerated storage room or the freezer compartment of the electric refrigerator, wherein the described shipskanalabdeckplatte is mounted on the heat insulation rear wall of cold storage room or freezer and a lower half part with a relatively wide gap to the heat insulation rear wall and a upper half part with a relatively narrow gap to the heat insulation rear wall comprises.
  • the described evaporator and fan are mounted between the lower half portion of the air duct cover plate and the heat insulation back plate, and the described slanted air outlet openings are mounted on the upper half portion of the air duct cover plate.
  • the described air outlet openings on the shipskanalabdeckplatte have at the opening inwardly inclined tongue parts, whereby obliquely upward sloping air outlet openings are formed.
  • the described air outlet openings on the Lucaskanalabdeckplatte have at the opening to the outside oblique tongue parts, whereby obliquely downward sloping air outlet openings are formed.
  • the benefit of this invention is that oblique air outlets are used, thus preventing the airflow from being blown directly outside the door of the refrigerator, thereby reducing energy losses.
  • Figure 1 shows a three-dimensional scheme of an electric refrigerator this
  • Figure 2 shows a schematic representation of the air duct system of the refrigerator storage room of the refrigerator from Figure 1.
  • Figure 3 shows a schematic representation of the air channel system of the freezer compartment of the refrigerator from Figure 1.
  • an electric refrigerator of one embodiment of this invention comprises a cabinet body 1 formed by a thermally insulated housing, this cabinet body being located above a cold store room 2 (see Figure 2) and a freezer room 3 (see Figure 3). which are arranged side by side.
  • the cold storage room 2 and the freezer compartment 3 together form the inner receiving space of the cabinet body 1.
  • a cold storage room door 4 for closing the cold storage room 2.
  • the freezer compartment is a freezer compartment door 5 for closing the freezer compartment 3.
  • Freezer compartment On the freezer compartment door 5 is located in Freezer compartment, the water and ice dispensing opening 50. The pieces of ice produced by the automatic ice cream maker can be dispensed through this water and ice dispensing opening 50.
  • the cold storage room 2 has a heat insulating rear wall 10 formed of heat insulating material.
  • the air duct system of the cold storage room is mounted on the heat insulating rear wall 10.
  • This air duct system comprises the Luftkanalabdeckplatte 60, the evaporator 63 of the cold storage room and the fan 64 of the cold storage room.
  • Between the Heilkanalabdeckplatte 60 and the heat insulation back wall is a certain gap.
  • the Heilkanalabdeckplatte comprises a lower half portion 61 with a relatively large distance from the heat insulation rear wall and an upper half portion 62 with a relatively small distance from the heat insulation rear wall.
  • the design of the lower half portion 61 with a relatively large gap serves to have sufficient space for receiving the evaporator 63 of the cold storage room available.
  • the design of the upper half part 62 with a relatively small gap allows on the one hand to provide the cold storage room with a larger usable space, and on the other hand to let the fan 64 of the cold storage room driven air flow flow even more concentrated in relatively small space.
  • the fan 64 is mounted horizontally above the evaporator 63 of the cold storage room.
  • the horizontally mounted fan allows the air flow, without having to rebound, be sucked through the evaporator 63 of the cooling storage space and blown directly to the upper half portion 62 of the Lucaskanalabdeckplatte 60.
  • On the upper half portion 62 of the Heilkanalabdeckplatte 60 are directed to the cooling storage room 2 air outlet openings 620.
  • the air outlet openings 620 are provided with an inclined tongue portion 622.
  • the tongue portion 622 is bent inwardly relative to the air channel cover plate 60.
  • 620 forms at the points of the air outlet openings above oblique angle.
  • the blown from the air outlet openings 620 air flow blows after passing through the guide of the tongue portion 622 in an upward oblique direction in the cold storage room. 2
  • the structure of the air duct system of the freezer compartment 3 resembles the structure of the air duct system of the cold storage compartment 2 in Figure 2.
  • the difference is as follows: Since the top of the freezer compartment 3 is equipped with an automatic ice maker 24, at the top of the upper half portion 72 of Heilkanalabdeckplatte 70 an upward air outlet opening 724 attached.
  • the air flow which passes through this air outlet opening 724 can be guided into the automatic ice machine 24 and used especially for the preparation of ice chips.
  • the above is a relatively optimal embodiment of this invention.
  • General technical personnel in this field can also adapt the above procedure in a suitable way, on the basis of specific requirements, without the hassle of creative work.
  • the obliquely upwardly directed air flow which is led inwardly obliquely from the tongue parts of the air outlet openings on the air duct cover plate of this embodiment, can also be adapted such that the tongue parts lead the obliquely downwardly directed air flow obliquely, if the effect is achieved, that the airflow is blown out obliquely.
  • these suitable adaptations should be within the scope of the claims of this utility model.
