Beverage cooling apparatus

Abstract

A beverage cooling apparatus includes a cooling module, a liquid tank, and a control unit. The cooling module comprises a compressor, a condenser, a flow controller, an evaporator and a plurality of circulating pipes. The compressor, the condenser, the flow controller and the evaporator are serially connected via each circulating pipe to form a closed circle for providing a conductive medium to circulate in the closed circle. The condenser has a fan. The liquid tank has a lateral wall. The evaporator is arranged adjacent to the lateral wall of the liquid tank, wherein a temperature sensor is arranged within the liquid tank. The control unit is electronically connected with the fan of the condenser and the temperature sensor respectively, wherein the control unit controls the fan to start/stop and further controls the rotational speed of the fan. Therefore, the compressor has long operation life because the compressor is not frequently start and stop.

1 . A beverage cooling apparatus comprising:
 a cooling module including a compressor, a condenser, a flow controller, an evaporator and a plurality of circulating pipes serially connecting the compressor, the condenser, the flow controller, and the evaporator to form a closed circle for providing a conductive medium to circulate in the closed circle, with the condenser including a fan;   a liquid tank having a lateral wall, with the evaporator being arranged adjacent to the lateral wall of the liquid tank, and with a temperature sensor provided within the liquid tank; and   a control unit electronically connecting to the fan of the condenser and the temperature sensor respectively;   wherein the control unit controls the fan to start or stop.   
     
     
         2 . The beverage cooling apparatus as claimed in  claim 1 , wherein the control unit controls a rotational speed of the fan. 
     
     
         3 . The beverage cooling apparatus as claimed in  claim 2 , wherein the control unit controls the rotational speed of the fan in accordance with a temperature detected by the temperature sensor. 
     
     
         4 . The beverage cooling apparatus as claimed in  claim 1  further comprising a bypass pipe, with one end of the bypass pipe connected with one of the circulating pipes communicated between the compressor and the condenser, with the other end of the bypass pipe connected with another one of the circulating pipe communicated between the evaporator and the flow controller, and with the bypass pipe having a control valve. 
     
     
         5 . The beverage cooling apparatus as claimed in  claim 4 , wherein the control valve is a solenoid valve, with the solenoid valve electronically connected with the control unit for the control unit to open or close the solenoid valve. 
     
     
         6 . The beverage cooling apparatus as claimed in  claim 5 , wherein the control unit controls the solenoid valve to open or close in accordance with a temperature detected by the temperature sensor. 
     
     
         7 . The beverage cooling apparatus as claimed in  claim 1 , wherein another temperature sensor is further provided on one of the circulating pipes connected between the compressor and the condenser. 
     
     
         8 . The beverage cooling apparatus as claimed in  claim 7 , wherein the another temperature sensor is electronically connected with the control unit.
