Technical field
The present invention is a kind of attemperating unit, and especially a kind of electronic cooling attemperating unit is mainly used in the compressor cooling occasion on the water dispenser.
Background technology
Before the present invention makes; Existing attemperating unit mainly is that kapillary, bulb, cold-producing medium are formed; Cold-producing medium is through the shrinkage of kapillary heat expansion, and the sense of control thermometer bulb is to reach the purpose of control temperature, and its major defect is the restriction that the temperature of its control receives variation of ambient temperature; Cause that temperature control is inaccurate, power consumption is big, influence the functions of use and the serviceable life of product.
Summary of the invention
Task of the present invention is the defective that overcomes prior art, and the present invention provides a kind of and has that rational in infrastructure, temperature precise control, power consumption are little, the electronic cooling attemperating unit of long service life.
When the present invention solves the problems of the technologies described above the technical scheme that is adopted:
A kind of electronic cooling attemperating unit; Comprise pcb board, relay, transformer, computer chip, environment temperature probe, cold water temperature probe and refrigerator temp probe; Said relay, transformer, computer chip, environment temperature probe, cold water temperature probe and refrigerator temp probe are installed on the said pcb board; The contact switch of said relay is the power of compressor switch; The low-pressure side of said transformer is connected with computer chip, and said computer chip is popped one's head in said environment temperature, the control end of cold water temperature probe, refrigerator temp probe and relay is connected; Said computer chip comprises:
The pattern adjustment module in order to according to the corresponding sequence of environment temperature with turn-on temperature, shutdown temperature, is confirmed turn-on temperature and shutdown temperature according to current environment temperature;
Temperature control modules, in order to the temperature that records when environment temperature probe or cold water temperature probe during greater than turn-on temperature, pilot relay contact switch closed action; The temperature that records when environment temperature probe and cold water temperature probe is during all less than shutdown temperature, the contact switch disconnection of pilot relay.
Further, the contact switch two ends of said relay are connected with the input inserted sheet with the output inserted sheet respectively.
Advantage of the present invention is: when environment temperature probe induced environment temperature variation; Temperature through computer chip control cold water temperature probe, refrigerator temp probe; Thereby pilot relay is exported inserted sheet through relay control compressor, thereby is reached the duty of accurate control temperature and compressor; Energy consumption is little, long service life.
Description of drawings
Fig. 1 is a kind of synoptic diagram of electronic cooling attemperating unit.
Embodiment
Below in conjunction with implementing the present invention is described in further detail:
Like Fig. 1; A kind of electronic cooling attemperating unit; Comprise pcb board 10, relay 4, transformer 5, computer chip 9, environment temperature probe 1, cold water temperature probe 2 and refrigerator temp probe 3; Said relay 4, transformer 5, computer chip 9, environment temperature probe 1, cold water temperature probe 2 and refrigerator temp probe 3 are installed on the said pcb board 10; The contact switch of said relay 4 is the power of compressor switch, and the low-pressure side of said transformer 4 is connected with computer chip 9, and said computer chip 9 is connected with the control end of said environment temperature probe 1, cold water temperature probe 2, refrigerator temp probe 3 and relay 4; Said computer chip comprises:
The pattern adjustment module in order to according to the corresponding sequence of environment temperature with turn-on temperature, shutdown temperature, is confirmed turn-on temperature and shutdown temperature according to current environment temperature;
Temperature control modules, in order to the temperature that records when environment temperature probe or cold water temperature probe during greater than turn-on temperature, pilot relay contact switch closed action; The temperature that records when environment temperature probe and cold water temperature probe is during all less than shutdown temperature, the contact switch disconnection of pilot relay.
Further, the contact switch two ends of said relay 4 are connected with input inserted sheet 7 with output inserted sheet 6 respectively.
220V supply socket 8 is connected with the high-pressure side of transformer 5, and through the transformer step-down, the low-pressure side of transformer is connected with computer chip 9; Relay 4 is connected Ei with the power of compressor line, and the contact switch of relay has served as the effect of power of compressor switch, and relay 4 is controlled by computer chip 9;
When the environment temperature 1 induced environment temperature variation of popping one's head in; Change turn-on temperature and shutdown temperature through computer chip 9; Extract the temperature of cold water temperature probe 2, refrigerator temp probe 3 by computer chip 9; Thereby pilot relay 4 is exported inserted sheets 6 through relay 4 control compressors, thereby is reached the duty of accurate control temperature and compressor; When cold water temperature probe 2, refrigerator temp probe 3 were sensed the shutdown temperature of computer chip 9 settings, relay 4 quit work, thereby compressor quits work; When cold water temperature probe 2, refrigerator temp probe 3 were sensed the turn-on temperature of computer chip 9 settings, relay 4 was started working, thus compressor starts work, and energy consumption is little, long service life.
In the present embodiment,, be provided with different turn-on temperatures and shutdown temperature, for example: if environment temperature smaller or equal to 28 ℃, set turn-on temperature to be 8 ℃ to be 5 ℃ with shutdown temperature for the difference of environment temperature; If environment temperature is greater than 28 ℃ and smaller or equal to 35 ℃ situation, it is 7 ℃ with shutdown temperature that turn-on temperature is 11 ℃; If environment temperature is greater than 35 ℃, it is 9 ℃ with shutdown temperature that turn-on temperature is 13 ℃; Be provided with changeless turn-on temperature and shutdown temperature with respect to prior art, can effectively cut down the consumption of energy.
