The specific embodiment
Referring to Fig. 1～2, this cold and hot insulating box adopts compressor refrigeration system and ptc heater to carrying out temperature control in the case, can 0～50 ℃ of temperature control scope.Refrigeration system is made up of parts such as compressor, condenser, device for drying and filtering, capillary, evaporimeter, reservoirs, and evaporimeter is inflation type evaporimeter or coil evaporator or finned evaporator or tube-in-sheet evaporator.Back top at casing 1 is provided with fan chamber 5, a built-in DC fan, and box house dress layer frame 6, rack 9 is equipped with in the bottom, bottom half dress leg 7, door body 2 is the luxury glass door or the foaming doors of inner filling heat insulator, there is an envelope 8 inboard.Electric-control system is made up of display control board 3, cpu power plate 10, compressor 12, ptc heater 11, illuminating lamp 4, fan, the first-class electrical part of temperature-sensitive, and each electrical part all is electrically connected with the cpu power plate.Insulating box comes temperature in the regulating box by refrigeration and heating, add thermal recovery PTC thermistor ceramic heater, the PTC element is installed in the aluminum pipe and with aluminum pipe and insulate, and fin or grooved fin are set outside aluminum pipe, PTC can choose the product of SNHC serial model No., but is not limited thereto.Ptc heater is installed in the fan chamber 5 of insulating box, realizes the heat exchange mode of forced convertion by the operation of DC fan 50.The PTC operating circuit connects temperature protector and fuse, guarantees the safe in utilization of insulating box and temperature is controlled in the safe temperature scope.
The internal circuit of cold and hot insulating box comprises CPU and the memory cell that is connected with CPU and input, output module, input module comprises temperature sensor, be arranged on a temperature of the display control board on body top 3 is provided with module, after insulating box powers on, user's input temp is provided with, CPU judges the interior real time temperature of setting value and case, when two values differed certain value, CPU sent signal drive compression machine or heater work, and was undertaken by following rule:
Continuous a period of time of the temperature inside the box, perhaps when oven temperature, was spent less than design temperature T+a, ptc heater was worked immediately, if reach design temperature up to oven temperature, during less than design temperature T. after one section of the heater continuous operation simultaneously, can stop 5 minutes;
The each normal power-up start of compressor must be delayed time m second.Each conversion of operation state time of compressor all must be greater than m minute; When compressor accumulative total continuous operation t hour, stop 3 minutes.Insulating box is also established defrosting mode: compressor accumulative total is worked a period of time (as 24 hours), then stops 30 minutes, and under defrosting mode, fan does not stop.
When short circuit sensor or displays temperature surpass 50 ℃ etc. during abnormal conditions, the insulating box fault alarm, this moment, compressor was not worked, and fan is start-stop at interval, and n second is called out in the buzzing of buzzer certain interval of time.On display control board, the charactron flicker also shows fault-signal.
When compressor operating or heater work, fan moves always; When compressor quit work or heater when not working or temperature sensor when breaking down fan move at interval, can establish out usually and stop in 20 seconds 20 seconds, but under defrosting mode, make an exception.Insulating box also designs has the temperature memory function: insulating box can be remembered the preceding desired temperature of outage, and work on behind incoming call after outage.Even long-time use also need not the people and looks after.This insulating box also designs has the forced service function: press " LED " and " TEMP-" two keys simultaneously, enter the forced refrigeration pattern after 5 seconds, and after " machine open/close " key was pressed for 5 seconds, perhaps cut off the insulating box power supply after.Compressor returns to initial power-up state.Under compulsory mode, compressor is worked always, and heater is also worked always, and fan is worked always, and this compulsory mode is mainly used in detecting pattern (detect refrigeration, heating whether normal).
Establishing four touch sensitive key (or touching button) on the display control board 3 of insulating box forms.Comprise the switch (bright/as to go out), adjustment " TEMP+ " of machine open/close, illuminating lamp and " TEMP-" etc., under the state of displays temperature, touch or press " TEMP+ " or " TEMP-" key, just enter temperature control state is set, temperature control value that the initial value of screen display temperature control or last time are provided with and flicker, press this button once more, the temperature control value increasing or decreasing of flicker.Do not receive after several seconds that key information transfers demonstration the temperature inside the box automatically to.Generally establish two temperature sensors in the case, be separately positioned on the moderate position up and down on box house right side, so that interior maximum temperature of induction-box and minimum temperature, demonstration, control signal are got weighted average, and the precision of demonstration, temperature control is more accurate; The accurate demonstration, the hotbed that help constant temperature the temperature inside the box are even, constant.
Referring to Fig. 3～4, for the occasion of having relatively high expectations at some environmental noises, this cold and hot insulating box can also replace the mode of compressor cooling with semiconductor refrigerating mode or absorption refrigeration mode.At casing 1 inner top install bin intraoral illumination lamp 4, the top of casing 1 is provided with display board 3, casing 1 back middle part is provided with fan chamber 5, interior semiconductor cooling device and the PTC thermistor ceramic heater 11 placed, described semiconductor cooling device is by semiconductor chilling plate 13 and the radiating fin and the cold scattering fin that are separately positioned on cooling piece cold junction and hot junction, Hot-air fan 51 and thermantidote 50 reinforcement heat exchange effects respectively are installed outside radiating fin and cold scattering fin, be provided with fan guard in the corresponding thermantidote of cabinets cavity 50 positions, corresponding Hot-air fan 51 positions also are provided with fan guard on casing back shell, enter to prevent foreign matter.
This cold and hot insulating box purposes is very extensive, both can make the usefulness of family's preserved food products, can make medicine again and preserve the chamber of case, laboratory cultures microorganism, be used for the laboratory and store biological products, biological agent, dislysate, B ultrasonic liquid are heated, unit stores tool box, laboratory test case or the like of measurement instrument, is suitable for food service industry, purposes such as herding medicine, biological hatching.Control system of the present utility model makes that the temperature inside the box is even, constant, safe in utilization, power saving, more save worry.This cold and hot insulating box can be realized from deepfreeze to 48 ℃ constant temperature adjustable continuously, and temperature range can be accurate to 1 ℃, and the error range of displays temperature and actual temperature can reach the amplitude less than ± 1.5 ℃, fully satisfies the requirement that the user uses.
