Definitions

  • the embodiments described herein relate to a detachable quick-freezing food storage case.
  • refrigerators capable of quick-freezing food and thereby locking in moisture and nutrients in the food are gaining popularity among customers.
  • Most refrigerators on the market thus are provided with a quick-freezing function, yet the temperature reduction effect is attained basically through prolonging the run time.
  • the extended time taken for cooling prevents moisture and nutrients of fresh food from being rapidly locked in, thus failing to ensure food quality.
  • the long run time results in excessive power consumption.
  • customers want to quick-freeze only the fresh food just purchased.
  • An objective of the present embodiments is to overcome the foregoing shortcomings and provide a detachable quick-freezing food storage case.
  • the food storage case can lock in moisture and nutrients in fresh food in a timely manner.
  • the food storage case is detachable, making it convenient for customers to use refrigerator space efficiently.
  • the storage case includes a storage case body fitting within a freezer compartment liner through a pull mechanism, and a quick-freezing fan assembly integrally assembled with a rear part of the storage case body.
  • the quick-freezing fan assembly includes a quick-freezing fan support secured to the storage case body and a quick-freezing fan securely mounted on the quick-freezing fan support.
  • the quick-freezing fan support includes an air inlet positioned in accordance with the quick-freezing fan.
  • the storage case body includes a return air inlet.
  • the quick-freezing fan support surrounds any one of the air outlets on a cold air duct board, to form an air circulation path from the air outlet, through the air inlet, to the return air inlet.
  • the storage case body also includes a cover fitting the storage case body.
  • the quick-freezing fan is connected to a main control panel.
  • the main control panel is connected to a display control panel.
  • a slide rail is respectively disposed on two side surfaces of the storage case body.
  • the freezer compartment liner includes guide rails fitting the slide rails.
  • a cross section of the quick-freezing fan support is in a shape of a right triangle.
  • a surface on a leg side is attached to the cold air duct board, and a surface on a hypotenuse side is fitly secured to an oblique surface of a rear part of the storage case body.
  • the main control panel is disposed on a top part of the refrigerator.
  • the display control panel is disposed on a door body of the refrigerator.
  • the present innovation pertains to a quick-freezing food storage case dedicated to quick-freezing food in a storage case by using the overall cold energy in a refrigerator. Moisture and nutrients in fresh food can thereby be locked in a timely manner.
  • the storage case is also detachable, making it convenient for customers to use refrigerator space efficiently.
  • the terms "upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the device as oriented in FIG. 1 .
  • the device may assume various alternative orientations and step sequences, except where expressly specified to the contrary.
  • the specific devices and processes illustrated in the attached drawings and described in the following specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.
  • the quick-freezing fan assembly includes a quick-freezing fan support 2 secured to the storage case body 1 and a quick-freezing fan 3 securely mounted on the quick-freezing fan support 2.
  • the quick-freezing fan support 2 includes an air inlet positioned in accordance with the quick-freezing fan 3.
  • the storage case body 1 includes a return air inlet 4.
  • the quick-freezing fan support 2 surrounds one of the air outlets 6 on a cold air duct board 5. That is, the quick-freezing fan support 2 covers one air outlet 6 on the cold air duct board 5 to form an air circulation path from the air outlet 6, through the air inlet, to the return air inlet 4.
  • the air outlet 6 at the upper right corner of the cold air duct board 5 is selected in this embodiment.
  • the storage case body 1 also includes a cover 7 fitting the storage case body.
  • the quick-freezing fan 3 is connected to a main control panel 20.
  • the main control panel 20 is connected to a display control panel 30.
  • a slide rail 8 is respectively disposed on two side surfaces of the storage case body 1.
  • the freezer compartment liner 10 includes guide rails 11 fitting the slide rails 8.
  • a cross section of the quick-freezing fan support 2 is in a shape of a right triangle.
  • a surface of a leg side is attached to the cold air duct board 5.
  • a surface on a hypotenuse side is fitly secured to an oblique surface of a rear part of the storage case body 1.
  • a projecting edge is disposed on two sides of the slope of the quick-freezing fan support 2; and a first positioning hole 21 is provided on each projecting edge.
  • the rear part of the storage case body 1 includes second positioning holes 12 fitting the first positioning holes 21.
  • main control panel 20 is disposed on a top part of the refrigerator; and the display control panel 30 is disposed on a door body of the refrigerator.
  • the main control panel 20 sends out a signal.
  • an original freezing fan in the refrigerator runs at low speed, and an air outlet is kept at a positive pressure to prevent air backflow.
  • the quick-freezing fan 3 in the storage case body 1 runs at a high speed, such that most cold energy absorbs cold air from the air outlet 6 on the cold air duct board 5 and delivers the cold air into the storage case body 1 to quickly freeze the food. Then, the return air is delivered to the freezer compartment through the return air inlet 4, and the return air goes back to an evaporator 9.
  • the quick-freezing fan stops after running for a predetermined time period T (hours), after which the refrigerator automatically exits the quick-freezing function and resumes the normal mode. If food quick-freezing is required again, the quick-freezing function needs to be enabled again by using the display control panel 30. If the refrigerator is in an off state when the quick-freezing function is being set, the refrigerator is first forcibly turned on through the main control panel. Next, the freezing fan is commanded to run at a low speed and the quick-freezing fan is commanded to run at high speed.
