Among them, single-temperature and dual-temperature freezers are two common types. Dual-temperature freezers have two independent temperature areas, namely the refrigerator and freezer. These two areas are equipped with independent temperature controllers, which can adjust the temperature independently as needed. Usually, the temperature of the refrigerator is set between 0 degrees and 10 degrees, which is suitable for preserving vegetables, fruits, beverages and other foods that need to be kept fresh; while the temperature of the freezer is set between 0 degrees and minus 12 degrees, which is suitable for long-term storage of meat, fish, ice cream and other foods that need to be frozen.

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Reference Figure 1 , Figure 2 and Figure 3An energy-saving multi-temperature zone freezer includes a freezer 1, on which a freezer cover 2 is installed. The freezer cover 2 is L-shaped, and a notch is provided on the freezer 1, which can not only match the freezer cover 2, but also facilitate staff to take out items inside. It is particularly noted that the freezer 1 and the freezer cover 2 are prior art and will not be described in detail here.

[0046] Reference Figure 4 and Figure 5 A sealing member 3 is installed on the freezer cover 2. When the freezer cover 2 is turned over, the sealing member 3 can be attached to the freezer 1, thereby sealing the freezer 1. The sealing member 3 includes a sealing frame 31 fixedly connected to the freezer cover 2. The lower end of the sealing frame 31 is fixedly connected to a rubber pad 32. The lower end of the rubber pad 32 is fixedly connected to an air bag ring 33 connected thereto. The inner top end of the sealing frame 31 is fixedly connected to an air cylinder 34. The air cylinder 34 is provided with a movable seat 35 that can be reset. It is particularly noteworthy that the movable seat 35 includes a piston plate and a spring. The two ends of the spring are respectively connected to the inner top end and the piston plate of the air cylinder 34. The input end of the air cylinder 34 is connected to the rubber pad 32 through a connecting pipe 36. The lower end of the movable seat 35 is fixedly connected to a heat insulation board 37 that passes through the side wall of the air cylinder 34 and extends to the bottom. The lower end of the heat insulation board 37 is fixedly connected to an insulation rubber head 38.

[0047] In actual operation, when the user covers the freezer cover 2, the airbag ring 33 on the rubber pad 32 will come into contact with the freezer 1, so that the airbag ring 33 can be squeezed, so that the gas in the airbag ring 33 can enter the air cylinder 34. When the air enters the air cylinder 34, the movable seat 35 can be moved, and the heat insulation board 37 can be further moved downward, so that the sealing and heat preservation effect of the sealing frame 31 and the rubber pad 32 can be better. At the same time, the heat insulation rubber head 38 can avoid damage to the heat insulation board 37. When the freezer cover 2 is lifted, since the airbag ring 33 is not affected by the squeezing force, the movable seat 35 can be reset under the influence of the spring, and the device can be used normally next time.

It is particularly noteworthy that one end of the fitting rubber strip 54 is arc-shaped. Therefore, when the extrusion rubber strip 43 is on one side of the fitting rubber strip 54, the soft rubber strip 53 and the fitting rubber strip 54 can be squeezed, and the non-return rubber strip 42 can be further squeezed, so that the sealing effect between the freezer cover 2 and the freezer 1 can be better.

[0051] Reference Figure 8 The freezer cover 2 is provided with a plurality of placement members 6, the placement members 6 including a placement box 61 arranged on one side of the freezer cover 2. It is particularly noted that the placement box 61 and the pull-out box 71 are both made of heat-insulating materials, thereby preventing the food in the placement box 61 and the pull-out box 71 from freezing, thereby ensuring the normal use of the device.
