Freezer and its control method

Abstract

This invention disclosed a freezer; and it's control method. The freezer includes the casing and the top board, on which a pad for placing wine cups and bottles and for easy wine pouring is equipped. There is a fast cooling chamber at the ventilation opening of the freezer, and a clapboard to adjust temperature is placed in the freezer, dividing the freezer into two chambers vertically. Air return openings are equipped above and beneath the clapboard. The said fast cooling chamber includes an air outlet pipe. The pipe is fixed on the wall of the freezer, just wrapping the ventilation opening. The said clapboard to adjust temperature includes a board, sealed with tapes at both front and back, making the front part joint the glass door and the back part joint the internal wall of the freezer. At the same time, the air return opening can be open or closed dependent on need to form different temperature control of the fast cooling chamber and the two chambers.

1 . A freezer, including the casing, top board, internal box, heat insulation door, freezing chamber, and rack, the said freezer is also equipped with ventilation opening, whereas a pad is set on the top board for placing wine cups and bottles and for easy wine pouring, a fast cooling chamber is set at the place of the ventilation opening of the internal box of the freezer, furthermore there are a clapboard to adjust temperature, and at least two air return openings that can be open and closed in the freezer. 
   
   
       2 . The freezer of  claim 1  wherein a groove made on the said top board, the said pad is placed in the groove, one side of the pad is the decorated surface, the other side is divided into two parts, one part is pressed into a step shaped groove and the other is flat, water guiding groove for storing water is made at the periphery of the flat board, integrated with the step shaped groove. 
   
   
       3 . The freezer of  claim 2  wherein, on the steps of the step shaped groove there is a holed-clapboard with many holes where wine cups can be put and spilled wine can flow into the step shaped groove through the holed-clapboard, the flat surface of the said pad is set with skid-proof raised dots, or skid-proof groove matching the shape of the items placed on. 
   
   
       4 . The freezer of  claim 1  wherein, the said fast cooling chamber includes an air outlet pipe, and the pipe is fixed on the wall of the freezer, just wrapping the ventilation opening. 
   
   
       5 . The freezer of  claim 1  wherein, the said clapboard to adjust temperature includes a board, sealed with tapes at both front and back, making the front part joint the glass door and the back part joint the internal wall of the freezer, it isolates the upper and lower spaces to keep the temperature constant in both upper and lower chambers. 
   
   
       6 . The freezer of  claim 1  wherein, the said air outlet pipe is a circular barrel or two joint circular barrels, the air outlet and the pipe are set in the upper space of the freezer, furthermore there are at least one the air return openings above and beneath the said clapboard respectively, temperature sensors are set near the air return openings respectively, one for each. 
   
   
       7 . The control method of the freezer of  claim 1  the said freezer has a control panel, on which are temperature display screen and control keys, including temperature adjusting key, light switch key, and fast switch power key, wherein when a wine bottle is put in the circular barrel of the pipe, the heat insulation door is closed, and the switch key of fast cooling is clicked, the internal fan is at work, the fast cooler begins, and low temperature air is blown out of the ventilation opening, directly and fast cooling the bottle. 
   
   
       8 . The control of  claim 7  wherein, when the item enters fast cooler, you can select to close the opening of the clapboard if the lower chamber below the clapboard does not need temperature lowering. 
   
   
       9 . The control of  claim 7  wherein, when fast cooling a item, if the lower chamber below the clapboard needs temperature lowering, you can select to open the opening of the clapboard, while partially or fully opening the lower air return opening and opening the upper air return opening to form a circulation of the air. 
   
   
       10 . The control of  claim 8  wherein, when no items are put in the fast cooling chamber, you can adjust the upper and lower chambers at the same temperature through opening or closing the opening of the clapboard, the upper and lower air return openings 
   
   
       11 . The freezer of  claim 4  wherein, the said air outlet pipe is a circular barrel or two joint circular barrels, the air outlet and the pipe are set in the upper space of the freezer, furthermore there are at least one the air return openings above and beneath the said clapboard respectively, temperature sensors are set near the air return openings respectively, one for each.
