Description
Technical field
The utility model relates to a kind of refrigerator, especially relates to a kind of refrigerator of the device frosting that avoids evaporating.
Background technology
Along with the progress in epoch, the function of household electrical appliance is more and more perfect, as household electrical appliance representative one of refrigerator also in its technology of improvement progressively.
At present, refrigerator is when defrosting, Defrost heater is set near evaporimeter, with the condenser pipe surface transferring heat of thermal-radiating mode to evaporimeter, utilizes thermal-radiating mode to defrost, because current defroster is all arranged at refrigerator inside, the temperature of refrigerator inside can be made to raise while defrosting, this Defrost mode efficiency comparison is low, and can aggravate the freezing load of refrigerator simultaneously, thus increase the load of evaporimeter, the final cooling effectiveness reducing refrigerator.
Utility model content
The utility model proposes a kind of refrigerator of the device frosting that avoids evaporating, utilize thermal-radiating mode to there is the lower technical problem of efficiency to evaporator defrost to solve current refrigerator.
The utility model adopts following technical scheme to realize: a kind of refrigerator of the device frosting that avoids evaporating, the evaporimeter comprising refrigerating chamber, refrigerating chamber, compressor and be connected with compressor, arrange accommodation chamber in the outside top of refrigerating chamber, the end of this evaporimeter extends to accommodation chamber; Be arranged on the radiator in accommodation chamber and fixing fan on a heat sink, and this radiator muff-joint is connected on the end of this evaporimeter; Be fixedly installed heater on a heat sink; Set temperature sensor on the interior plate of refrigerating chamber, the interior plate of accommodation chamber is fixedly connected with control circuit board, and this temperature sensor and heater are all electrical connected with control circuit board.
Wherein, this heater is some stainless steel heating tubes or quartz heating-pipe, and stainless steel heating tube or quartz heating-pipe run through and be arranged in radiator.
Wherein, this control circuit board is provided with: the controller be connected with fan with temperature sensor, for heater provides the power circuit of working power, and is connected to controller, relay between power circuit and heater.
Compared with prior art, the utility model has following beneficial effect:
The utility model also arranges accommodation chamber separately outside refrigerating chamber and refrigerating chamber, and will be arranged in accommodation chamber after the end of evaporimeter socket radiator, the heat transfer area between radiator and evaporimeter be conducive to more greatly refrigerator fast-refrigerating; Simultaneously, heater is set on a heat sink, worked by control circuit board control heater, the heat that heater produces also conducts to evaporimeter fast through radiator, thus frosting in the device fast-refrigerating process that avoids evaporating, and heater is arranged in accommodation chamber, the heat that heater produces directly can't affect the refrigerating efficiency of refrigerating chamber and refrigerating chamber by heat radiation.In addition, the utility model also has that structure is simple, to realize cost low and be adapted to the feature of various refrigerator.

Fig. 2 is the syndeton schematic diagram between radiator, evaporimeter and heater;
Fig. 3 is the circuit modular structure schematic diagram of control circuit board.
Detailed description of the invention
Shown in composition graphs 1 and Fig. 2, the utility model proposes a kind of refrigerator 1 of the device frosting that avoids evaporating, this refrigerator 1 comprises: the refrigerating chamber 11 utilizing dividing plate to be separated up and down and refrigerating chamber 12; Compressor (not drawing in Fig. 1) and the evaporimeter 13 be connected with compressor, this evaporimeter adopts elongated condenser pipe to form, and the first end of evaporimeter 13 extends to refrigerating chamber 11 and refrigerating chamber 12; Arrange accommodation chamber 2 in refrigerating chamber 11 outside top, the second end of this evaporimeter 13 extends to accommodation chamber 2, is also provided with radiator 14 and is fixed on the fan 15 on radiator 14 in accommodation chamber 2, and the second end of evaporimeter 13 runs through with radiator 14 and is connected; Radiator 14 is fixedly installed heater 16; On the interior plate of refrigerating chamber 12, set temperature sensor 17, the interior plate of accommodation chamber 2 is fixedly connected with control circuit board 18, and this temperature sensor 17 is electrical connected with control circuit board 18.
In a preferred embodiment, heater is some stainless steel heating tubes or quartz heating-pipe, and stainless steel heating tube or quartz heating-pipe run through and be arranged in radiator 14, make stainless steel heating tube or between quartz heating-pipe and radiator 14, there is larger thermocontact area.
Shown in composition graphs 3, control circuit board 18 is provided with the controller (by chip microcontroller) be connected with temperature sensor 17, for heater 16 provides the power circuit of working power, and be connected to the relay between controller, power circuit and heater 16.
Radiator 14 has some radiating fins, and radiating efficiency is higher.When refrigerator work is in refrigerating state, compressor operation, refrigerant flows in evaporimeter 13, the heat drawn in refrigerating chamber 11 and refrigerating chamber 12 is delivered to radiator 14, now control circuit board 18 controls fan 15 and works, accelerate the flowing of radiator 14 superficial air, the heat of evaporimeter 13 second end is distributed through radiator 14, thus improve the refrigerating efficiency of refrigerator.
Temperature sensor 17 detects the temperature in refrigerating chamber 12 in real time, temperature data is fed back to the FPDP (FPDP of controller carries A/D sample circuit) of controller, when controller judge the temperature of refrigerating chamber 12 decline within the unit interval too fast and temperature lower than a certain preset value time, control fan 15 quits work and the normally opened contact of control relay closes, the path switched on power between circuit and heater 16, heater 16 is made to obtain electric starting working, heater 16 produces rapidly a large amount of heats and conducts to evaporimeter 13 second end through radiator 14, and via the condensing agent in evaporimeter 13 by carry heat to the first end of evaporimeter 13, thus make evaporimeter 13 first end be exposed in refrigerating chamber 12 can not frosting.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
