Background technology
At present; The defrosting of frozen type low temperature dehumidification machine normally relies on reversal valve to carry out reverse cycle defrost, and its system architecture generally is compressor, condenser, capillary, evaporimeter, reversal valve, blower fan, connection copper pipe arrangement and electrical control part, and its course of work is: when dehumidifier moves under low temperature environment; The evaporator surface frosting; The controller micro computer can be judged this state automatically, and in time sends the defrosting instruction, defrosts.At this moment; The electromagnetic switch valve coil gets the electric reversal valve switching-over that causes; The high temperature and high pressure gas that compressor is discharged at first gets into the evaporimeter heat release, thereby makes the white melting layer on its surface, passes through capillary, condenser then; Get back to compressor by air intake duct, this cyclic process is with normal just in time opposite when removing wet condition.After defrosting finished, solenoid directional control valve coil losing electricity, dehumidifier returned to the normal wet condition that removes again, so " dehumidifying---defrosting---dehumidifying " constantly circulation, thus guaranteed that machine also can operate as normal under low temperature environment.But this Defrost technology, system architecture are comparatively complicated, and cost is high, and takes the power consumption ability.
Summary of the invention
The utility model provides a kind of dehumidifier with intelligent defrosting function, and it is not only simple in structure, and cost is low, and energy consumption is low, and has saved reversal valve and copper pipe arrangement, has reduced cost.
The utility model has adopted following technical scheme: a kind of dehumidifier with intelligent defrosting function; It comprises the dehumidifier body; The dehumidifier body is provided with cooling cycle system; Cooling cycle system comprises compressor, condenser, capillary module and evaporimeter; The exhaust outlet of compressor is communicated with the input of condenser through blast pipe, and the output of condenser is communicated with the input of evaporimeter through capillary module, and the output of evaporimeter is communicated with the air entry of compressor through air intake duct; Compressor is connected the back successively and constitutes closed cooling cycle system with condenser, capillary module and evaporimeter; Described dehumidifier body also comprises air circulation system and defrosting ventilation controller, and described air circulation system comprises screen pack and centrifugal fan, and screen pack is arranged on the air inlet of dehumidifier; Be positioned at an outdoor side at air inlet and be provided with temperature sensor I and humidity sensor; On the heat exchanger tube of evaporimeter, be provided with the temperature sensor II of evaporimeter heat exchanger tube, centrifugal fan is positioned at the wind outlet of dehumidifier, and the signal output part of the signal output part of temperature sensor I, the signal output part of humidity sensor and temperature sensor II all is connected with the input of defrosting ventilation controller; The output of defrosting ventilation controller is connected with the motor of centrifugal fan; Temperature sensor I, humidity sensor and temperature sensor II send to the defrosting ventilation controller with the signal that detects, and the defrosting ventilation controller compares the processing back with signal centrifugal fan is controlled, thereby defrosts and ventilating through centrifugal fan.
Described defrosting ventilation controller is a microcomputer controller.
The utlity model has following beneficial effect: after having adopted above technical scheme, the system architecture that the utility model is simplified is omitted reversal valve and copper pipe arrangement, has not only practiced thrift cost, and has simplified the structure.The utility model adopts air circulation system and defrosting ventilation controller; It can utilize the circulating air operation that defrosts; Not only practiced thrift the energy greatly; And the defrosting ventilation controller can control the defrosting operation exactly, guaranteed the accuracy and the validity of defrosting, finally guaranteed to remove the operation of wet trade.

The specific embodiment
In Fig. 1; The utility model provides a kind of dehumidifier with intelligent defrosting function; It comprises the dehumidifier body; The dehumidifier body is provided with cooling cycle system; Cooling cycle system comprises compressor 1, condenser 2, capillary module 3 and evaporimeter 4, and the exhaust outlet of compressor 1 is communicated with the input of condenser 2 through blast pipe 5, and the output of condenser 2 is communicated with the input of evaporimeter 4 through capillary module 3; The output of evaporimeter 4 is communicated with the air entry of compressor 1 through air intake duct 7; Compressor 1 is connected the back successively and constitutes closed cooling cycle system with condenser 2, capillary module 3 and evaporimeter 4, described dehumidifier body also comprises air circulation system and defrosting ventilation controller 8, and defrosting ventilation controller 8 is a microcomputer controller; Described air circulation system comprises screen pack 9 and centrifugal fan 10; Screen pack 9 is arranged on the air inlet of dehumidifier, is positioned at an outdoor side at air inlet and is provided with temperature sensor I11 and humidity sensor 12, on the heat exchanger tube of evaporimeter 4, is provided with the temperature sensor II 13 of evaporimeter heat exchanger tube; Centrifugal fan 10 is positioned at the wind outlet of dehumidifier; The signal output part of the signal output part of the signal output part of temperature sensor I11, humidity sensor 12 and temperature sensor II 13 all is connected with the input of defrosting ventilation controller 8, and the output of defrosting ventilation controller 8 is connected with the motor 6 of centrifugal fan 10, and temperature sensor I11, humidity sensor 12 and temperature sensor II 13 send to defrosting ventilation controller 8 with the signal that detects; Defrosting ventilation controller 8 compares the processing back with signal centrifugal fan 10 is controlled, thereby defrosts and ventilating through centrifugal fan 10.
In dehumidifier dehumidified running, temperature sensor I11 and humidity sensor 12 detected the temperature and humidity at air inlet place respectively, and the temperature sensor II of evaporimeter heat exchanger tube detects the temperature of evaporimeter heat exchanger tube; Then detected signal being sent to defrosting ventilation controller 8 analyzes and judges; When evaporimeter heat exchanger tube temperature＞defrosting incision temperature (0 ℃), then keep the dehumidifying running status, when evaporimeter heat exchanger tube temperature≤defrosting incision temperature; Defrosting ventilation controller 8 picks up counting; The ventilation controller 8 that defrosts simultaneously calculates according to the temperature sensor I11 at air intake place and the data-signal parameter of humidity sensor 12, calculates air status parameter this moment, continues the relation of running time thereby draw frost layer ulking thickness with dehumidifying; Like this can be through judging that frosting thickness is confirmed the defrosting operating point on the heat exchanger; Compressor shutdown during defrosting, centrifugal fan 10 are ventilated and are removed evaporator surface frost layer, and the length of defrosting time is relevant with factors such as environment temperature, frost thickness, fin material and structure, a pitch of fins, wind speed; It withdraws from the defrosting condition and considers that not only detected evaporimeter heat exchanger tube temperature returns to the time of set temperature value (4 ℃); Also must consider the time of aluminium fin condensed water emptying, otherwise fin ponding can freeze in the next dehumidifying cycle, make that defrosting next time is more difficult; Must guarantee that in addition defrosting time is not higher than 30% of whole dehumidifying defrost periods; Therefore comprehensive above-mentioned three factors of ventilation time that defrost are confirmed, press setting program control by defrosting ventilation controller 8, return except that wet condition after defrosting is withdrawed from.
