The evaporator is installed in the inside of the current storage tank, the compressor 92, the condenser %, the flow: == the device = is connected in series by the - circulation line %, and the % pipe is formed - closed Peng . In addition, the liquid storage tank 9 i (10) has a single unit and the temperature detecting unit 97 and the compressor 92 are electrically connected to the prefabricating unit 95. The _ ring line 96 is for the circulation of the refrigerant, and the refrigerant is condensed by the compressor 92.

However, the compressor 92 is limited to a high and low pressure balance problem and must be waited for at least two to three minutes after the shutdown to be restarted to avoid causing the compressor 92 to be overloaded and damaged. Therefore, when the temperature of the beverage inside the liquid storage tank 91 of the conventional structure is lower than the low temperature threshold, and the compressor 92 has stopped operating, if the inside of the liquid storage tank 91 is required to be refilled with the beverage, and the supplement The injected normal temperature drink raises the temperature inside the reservoir 91 above the high temperature threshold.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The features and advantages of the present invention will become more apparent from the following description. === The 砀cooling unit 1 comprises a 1 = controller 16, an evaporator 13, a plurality of circulating tubes 2 t: 12, a controller 16 and an evaporator core to form a closed interesting path. Each of the circulation tubes 14 :: two conductive agents circulates and the conductive agent is preferably a refrigerant, and the conductive agent is 'demon?: 11 after compression' will be between the condenser 12 (or the actuator 13) The volume of the test can be selected as - capillary, - _ or - restrictor, and 201100734 _ conductive agent pressure reduction east expansion into the condenser system contains a liquid state of the two dishes. And the heat sink (2)-side, the tandem joint, and the side surface (2) are disposed in the vicinity of the auxiliary flow (four) portion 12 Γ == reliance portion (2), The evaporator (4) is rapidly deflated and condensed. The liquid placed in the liquid storage #2 bis is only 3 2, and the evaporator 13 can be disposed on the inner peripheral wall of the raft, and the stipulations of the sufficiency And the device 13 is disposed in the liquid storage tank in a spiral shape; and in addition, the temperature detecting unit 2 in the 5 liter liquid storage tank 2 is connected to the circulation tube 14 between ί== ^^=22 and the two temperature side materials 21, 22 and the fan 122 of the condenser are electrically connected to the control unit 3. The control unit 3 can determine the temperature in the liquid storage tank 2 The temperature conditions sensed by the first 21 are expected to be within the preset temperature range and refer to the temperature difference sensed by the three temperature sensing unit 2, and the control fan 122 is selected to be activated or not. When the control unit 3 controls the wind, the control unit 3 can further control the rotation speed of the fan 122 according to the temperature value sensed by the two temperature detecting units 21, 22, and the fan 122 The rotation speed is preferably proportional to the temperature value sensed by the temperature detecting unit 21 in the liquid storage tank 2. Referring to FIG. 2 again, the first embodiment is used to cool the beverage to a preset temperature. The temperature range, the preset temperature range is preferably lower than the room temperature, and the preset temperature range has a high temperature threshold and a low temperature of 201100734. In the operation of the first embodiment, the beverage is injected at room temperature. The inside of the wrong tank 2 is activated by a control switch, and the compressor 11 starts to operate. At the same time, the temperature detecting unit 21 of the liquid storage tank 2 senses that the temperature of the beverage is higher than the high temperature threshold. The control unit 3 controls the condensation The fan 122 of the device 12 operates 'the heat energy generated by the compressor 11 compressing the conductive agent can rapidly dissipate heat in the heat dissipating portion 121, and the temperature of the conductive agent flowing into the evaporation 13 is lowered. The heat exchange performance is better, and the relative high temperature of the beverage can be quickly absorbed to achieve the cooling and cooling effect. When the temperature of the beverage inside the liquid storage tank 2 continues to decrease, the temperature detecting unit 21 senses that the temperature of the beverage is low. At the low temperature threshold, the control unit 3 controls the fan 122 of the condenser 12 to stop operating. At this time, the compressor U continues to operate, but since the fan 122 of the condenser 12 no longer assists the heat dissipation portion 121 to dissipate heat, Causing a decrease in the exothermic condensation performance of the condenser 12 and increasing the temperature of the conductive agent flowing into the evaporator 13, and the temperature may be relatively higher than the temperature of the beverage inside the liquid storage tank 2, and absorbing the relatively low temperature of the beverage, In order to gradually increase the temperature of the drink. When the temperature detector element 21 senses that the temperature of the beverage rises back between the 1% temperature threshold and the low temperature threshold, and the compressor Η continues to operate, the control unit 3 can be controlled. The fan 122 of the condenser 12 is activated or not. If the control unit 21 controls the fan 122 to operate, the speed of the fan 122 can be further controlled according to the temperature value sensed by the temperature detecting unit 21. When the speed of the fan 122 of the condenser 12 is accelerated, the heat dissipating portion 121 can be quickly released, and the temperature of the evaporating 201100734 is rapidly decreased. When the fan m of the condenser is low, the heat of the heat sink 121 is released. If the efficiency is reduced, the temperature of the transition can be lowered at a slower speed. At the same time, the temperature difference sensed by the reference temperature can be used to control the reservoir 2 more precisely. The internal beverage is warm and mixed, and the temperature is lowered at the high (four) threshold value, and the temperature of the beverage inside the liquid storage tank 2 can be precisely controlled by controlling the rotation speed of the fan 122 of the condenser 12, therefore, The embodiment may vary the temperature difference between the high temperature threshold and the low ship value, and the temperature change affects the taste and mouthfeel of the beverage. Please refer to FIG. 3 for the beverage cooling and warming of the second embodiment of the present invention, and also for the cooling unit 1, the cooling unit 1, the liquid storage tank 2, and the control unit 3, the cold unit 1, and the compression unit. The machine 11, the condenser 12, the first-stage controller 16, the evaporator 13 and the plurality of circulation pipes 14a, 14b, 14c are adjacent to the first embodiment, and the second embodiment is provided with a stone One end of the bypass pipe 15 is connected to the compressor 11 and the condensation i circulation pipe (4), so that one end of the bypass pipe 15 and the other end of the circulation system if the bypass pipe 15 is finely controlled by the flow control The circulation pipe 14b of 13 is arranged such that the bypass pipe 15 is further provided with the second pipe 14b to form a tee. Moreover, the bypass pipe 15 is magnetically closed: the door can be a pressure mechanical valve or a power to fix the pressure inside the pipe. When the valve 151 is a fixed surface ’, the valve 151 is forced to a predetermined pressure. For another example, when the trick door 151 - 10 - 201100734 is an electromagnetic switch, the valve 151 can receive the control signal of the control unit 3 to control the opening or closing of the valve 151, thereby controlling whether the bypass pipe 7 can The conductive agent is circulated. When the temperature detecting unit 21 of the liquid storage tank 2 senses that the temperature of the beverage is higher than the temperature threshold, the control unit 3 controls the fan 122 of the condenser 12 to operate to lower the temperature of the beverage. However, if the capacity of the beverage inside the liquid storage tank 2 is small at this time, the πσ temperature inside the liquid storage tank 2 may be too rapidly dropped to an excessively low temperature, and even if the control unit 3 immediately controls the violation The fan 122 of the condenser 12 stops working, but since the heat dissipating portion 121 of the condenser 12 still has a heat sink to assist heat dissipation, it still has a lower efficiency of exothermic condensation, so that the evaporator has a slower temperature recovery rate. When the control unit 3 can control the valve 151 to open, the bypass pipe 15 is turned on, and the conductive agent having a higher temperature can be compressed through the compressor u to directly flow to the evaporator via the bypass pipe 15 . 13. The temperature of the evaporator 13 can be quickly raised to prevent the beverage from affecting its quality or freezing due to excessively low temperatures for a long time. While the invention has been described in connection with the preferred embodiments described above, it is not intended to limit the scope of the invention. The technical scope of the invention is protected, and therefore the scope of the invention is defined by the scope of the appended claims. 201100734 [Simple description of the diagram] Figure 1: Schematic diagram of the conventional structure.
