However, it is to be understood that the device may assume various alternative orientations and step sequences, except where expressly specified to the contrary. It is also to be understood that 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 present innovation is further described below with reference to the accompanying drawings.
  • A detachable quick-freezing food storage case as shown in FIGS. 1, 2, 3, and 4, wherein the detachable quick-freezing food storage case includes a storage case body 1 fitting a freezer compartment liner 10 through a pull mechanism, and a quick-freezing fan assembly integrally assembled with a rear part of the storage case body 1. 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.
  • Further, 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. When no food needs to be quickly frozen, the storage case body 1 can be taken out, making it convenient for customers to use refrigerator space efficiently.
  • Further, 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. Specifically, 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. The quick-freezing fan support 2 and the storage case body 1 are fixed together by using screws.
  • Further, the 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.
  • Operating steps and principles related to the present utility model are as follows.
  • After the refrigerator is set to a quick-freezing function by using the display control panel 30, the main control panel 20 sends out a signal. In this case, 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. To ensure the low temperature in other parts of the freezer compartment, 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.
