Abstract:
An intelligent digital control apparatus for wine temperature includes a tub ( 10 ), a semiconductor cooling/heating device ( 20 ), a temperature sensing device ( 30 ) and a digital control panel ( 40 ). When the wine bottle is put in the tub ( 10 ), the semiconductor cooling/heating device ( 20 ) is activated to start cooling if the setting temperature is higher than the wine temperature. The semiconductor cooling/heating device ( 20 ) begins warming when the wine temperature decreases below the setting temperature. When the wine bottle is put in the tub ( 10 ), the semiconductor cooling/heating device ( 20 ) is activated to start heating if the setting temperature is lower than the wine temperature. The semiconductor cooling/heating device ( 20 ) begins warming when the wine temperature increases over the setting temperature. The intelligent digital control apparatus senses the temperature of the wine bottle disposed in the tub ( 10 ), and thereby intelligently controls the increasing or decreasing of the temperature in the tub ( 10 ) by reasonably arranging the position among the temperature sensing device ( 30 ), the semiconductor cooling/heating device ( 20 ) and the tub ( 10 ), so that the wine in the wine bottle can be adjusted to proper temperature, and the condition of the wine temperature can be further directly reflected with digital display.

         [0004]    People are more and more fastidious about food and drink as standard of living is rising continuously. Now, there are many brands of wine on the market. The flavor of most wine will be different when the wine temperature is changed. In general, a wine warmer is used to adjust the wine temperature when testing wine.

         [0066]    The temperature sensing device  70  can be a temperature sensing wire disposed on an inner side of the elastic metallic arm  53  for sensing the temperature of the elastic metallic arm  53  to get the temperature of the wine bottle indirectly. The temperature sensing device  70  is electrically connected to the electric control module  63 . 
         [0067]    The digital control panel  80  is mounted on the outer shell  52 . The digital control panel  80  includes a digital display  81  and an operating key unit  82 .

         [0070]    A test shows that the present invention is connected with external power supply at a room temperature of 25□; the temperature displayed on the LCD is the initial temperature of the wine sensed by the temperature sensing device; and the setting temperature in the tub is 10□. When the temperature is higher than 10□, the semiconductor cooling/heating device is activated to start cooling. To consider the problem that the data of the wine temperature displayed on the LCD in earlier three minutes is not steady, so the data is based on the date which is read after three minutes. When the setting temperature is lower than the wine temperature, the apparatus starts cooling. After sixty minutes, wine 750 ml will be lowered about 5±1□. After one hundred twenty minutes, the wine will be further lowered about 5±1□. When the setting temperature is higher than the wine temperature, the apparatus starts heating.

The power supply circuit  206  is further connected to a temperature protection circuit  209 . 
         [0078]    To practice the third embodiment, the wine bottle filled with wine is placed in the inner container  101 , with the wine bottle being contact with the curved metallic plate  105 . The temperature sensing device  300  disposed on the inner side of the curved metallic plate  105  direct senses the temperature of the wine bottle so that the real temperature of the wine is calculated and displayed on the digital display  401 . Like the first and second embodiments, the semiconductor cooling/heating device  200  is activated for working if the setting temperature is higher or lower than the wine temperature. Therefore, the details don&#39;t be repeated hereinafter. A test shows that under a room temperature of 25□, wine 750 ml at a temperature of 25 □ will be lowered about 5 □ within one hour; wine 750 ml at a temperature of 5 □ will be risen about 10 □ within thirty minutes. 
         [0079]    Compared with the first and second embodiments, the third embodiment uses the temperature sensing device to sense the temperature of the curved metallic plate for sensing the temperature of the wine bottle which is contact with the curved metallic plate. The semiconductor cooling/heating device is adapted to lower or rise the temperature in the inner container so that the wine in the wine bottle is adjusted to an appropriate temperature for a better flavor. The digital display is adapted to display the wine temperature direct, which is convenient when in use. However, the semiconductor cooling/heating device in the third embodiment is disposed on one side of the metallic wall (like the first embodiment), and the tub is composed of two inner containers. 
         [0080]    According to the aforesaid three embodiments, the cooling function of the semiconductor cooling/heating device adopts a software compensation method through a value collected by NTC (negative temperature coefficient) to compare and correct the real wine temperature which is displayed on the LCD. The heating function of the semiconductor cooling/heating device adopts PWM (pulse width modulation) to compare with the heating time of the cooling/heating plate for controlling the cooling/heating plate to work steadily within a desired temperature. 
         [0081]    The feature of the present invention is that the temperature sensing device, the semiconductor cooling/heating device and the tub are mounted at a proper position to sense the temperature of the wine bottle in the tub and then to rise or lower the temperature intelligently so that the wine in the wine bottle is adjusted to an appropriate temperature for a better flavor. With the temperature sensing device cooperated with the metallic parts to sense the temperature of the wine bottle, the wine temperature is displayed on the digital display. This is convenient when in use. 
         [0082]    Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
