[0002] An upright freezer is a type of freezer that is used to display or sell drinks. Like a freezer, its main principle is to use an evaporator, a condenser, and a compressor to control the deformation of Freon to lower the temperature inside the freezer. The objects placed inside and the moisture in the air are prone to condensation when the temperature drops. Condensation on the glass door will affect the line of sight, so it needs to be cleaned or an anti-condensation structure must be installed.

[0025] Among them, a driving shaft 803 is rotatably arranged on the front side of the intermediate frame 8, and a driving motor 804 for controlling the driving shaft 803 is fixedly arranged at one end of the intermediate frame 8; the driving shaft 803 and the transmission wheel 801 are connected by a bevel gear transmission; and a transmission gear A805 is fixedly arranged at the right end of the driving shaft 803.

[0027] like Figure 1-Figure 8 As shown, the cold air is released through the evaporator to directly cool the inner tank 2 and cool the air in the space behind the inner tank 2; the driving motor 804 is started at a fixed time to drive the driving shaft 803 to rotate, and the driving shaft 803 drives the transmission wheel 801 and the transmission gear A805 to rotate; When the transmission wheel 801 rotates, the eccentric slide bar 802 drives each group of U-shaped connecting frames 709 to move up and down alternately, and then repeatedly pushes the square piston 708 to do reciprocating motion in the variable volume chamber 703. When negative pressure is generated in the variable volume chamber 703, the cold air opens the lower one-way plate 705 to enter the U-shaped channel 702 and the variable volume chamber 703. When the variable volume chamber 703 is pressurized, the lower revolving door 706 is opened to be transported to the front side of the conveying channel 7. When the air passes through the dehumidification belt 601, the moisture is intercepted, and then it enters the lower connecting chamber 13, enters the rear circulation channels 5 on both sides, and is discharged from the rear grid holes 501 to cool the beverage; the pressurization causes the air to enter the front circulation channel 5 from the front grid holes 501, and is transported back to the rear and lower position of the inner tank 2 through the pipeline, thereby completing the cycle; At the same time, the transmission gear A805 rotates to drive the driven gear A9 to rotate, the driven gear A9 drives the transmission gear B10 to rotate, and the transmission gear B10 drives the driven gear B11 and the intermittent gear block 1101 to rotate; The variable volume chamber 703 above draws air from the air inlet 102, and then the air is discharged from the exhaust channel 103. The water generated at this time will enter the partition frame 401, and be transported to the condensation water tank 101 through the pipeline. The evaporator transfers heat to the condensation water tank 101, and evaporates the water to the outside.

[0028] Example 2: On the basis of Example 1, the upper connecting bin 13 can be optionally installed with a heater according to usage requirements. After being heated by the heater in the upper connecting bin 13, the dehumidification belt 601 is directly blown for heat drying. Since the dehumidification belt 601 is dehumidified by interception, it will become wet itself. Reverse blowing and heat drying can quickly dry the dehumidification belt 601, and an automatic feeding method is adopted. When a certain amount of air is transported, the intermittent gear block 1101 is used to drive the driven gear C12 to rotate. The driven gear C12 cooperates with the synchronous belt drive to drive the conveying roller 6 to rotate. The conveying roller 6 drives the dehumidification belt 601 to move upward, and the moisture-mixed part of the dehumidification belt 601 is moved to between the upper conveying channel 7 and the connecting bin 13.

[0029] Embodiment 3: Based on Embodiment 1, the object tray 3 is assisted by the side pulley 301 to be installed in the tray guide rail 202; The main function of the positioning seat 302 is to store beverages, but the refrigerator is not limited to storing only beverages; The style of the positioning seat 302 can be customized and installed as needed, or it can be chosen not to be installed and the integrated loading tray 3 can be directly used; The positioning seat 302 is installed by means of an elastic buckle 303 and can be unlocked from the bottom when dismantling; The elastic buckle 303 and the elastic bracket 304 are made of elastic plastic to reduce the cost. The cost can be increased as needed by selecting a more durable material.

[0030] Specific usage and function of this embodiment: In the present invention, when in use, the beverage is placed on the positioning seat 302, and the elastic bracket 304 is used to assist in fixing, and the revolving glass door is closed to complete the replenishment; The cold air is released through the evaporator to directly cool the inner tank 2 and cool the air in the space behind the inner tank 2; The driving motor 804 is started at a fixed time to drive the driving shaft 803 to rotate, and the driving shaft 803 drives the transmission wheel 801 and the transmission gear A805 to rotate; When the transmission wheel 801 rotates, the eccentric slide bar 802 drives each group of U-shaped connecting frames 709 to move up and down alternately, and then repeatedly pushes the square piston 708 to do reciprocating motion in the variable volume chamber 703. When negative pressure is generated in the variable volume chamber 703, the cold air opens the lower one-way plate 705 to enter the U-shaped channel 702 and the variable volume chamber 703. When the variable volume chamber 703 is pressurized, the lower revolving door 706 is opened to be transported to the front side of the conveying channel 7. When the air passes through the dehumidification belt 601, the moisture is intercepted, and then it enters the lower connecting chamber 13, enters the rear circulation channels 5 on both sides, and is discharged from the rear grid hole 501 to cool the beverage. At the same time, the pressurization causes the air to enter the front circulation channel 5 from the front grille hole 501, and is transported back to the rear lower position of the inner tank 2 through the pipeline, thereby completing the circulation; The transmission gear A805 rotates to drive the driven gear A9 to rotate, the driven gear A9 drives the transmission gear B10 to rotate, the transmission gear B10 drives the driven gear B11 and the intermittent gear block 1101 to rotate, and then when a certain amount of air is transported, the intermittent gear block 1101 is used to drive the driven gear C12 to rotate, the driven gear C12 cooperates with the synchronous belt drive to drive the conveying roller 6 to rotate, and the conveying roller 6 drives the dehumidification belt 601 to move upward, and the part of the dehumidification belt 601 mixed with moisture after dehumidification is moved to between the upper conveying channel 7 and the connecting chamber 13; The variable volume chamber 703 above draws air from the air inlet 102, which is heated by the heater in the upper connecting chamber 13, and then blown directly to the dehumidification belt 601 for heat drying, and then the air is discharged from the exhaust duct 103. The water generated at this time will enter the partition frame 401, and be transported to the condensation water tank 101 through the pipeline. The heat is transferred to the condensation water tank 101 through the evaporator, and the water is evaporated to the outside.
