Description
Technical field
The utility model relates to a kind of refrigerator, relates in particular to a kind of single round-robin system cooling system refrigerator that has chamber between two of refrigerating chamber and refrigerating chambers at least.
Background technology
Mechanical refrigerator of the prior art generally all comprises compressor, condenser, device for drying and filtering, refrigerating evaporator, refrigeration evaporator, they are connected to form refrigerating circuit in turn, usually with the temperature in the temperature control refrigerator of refrigerator evaporator, freezer temperature matches with temperature of refrigerating chamber under standard ambient temperature.The refrigeration work of this class refrigerator is most effective, and the structure of refrigeration pipe is also the simplest simultaneously, can use the compressor of less refrigerating capacity to realize higher refrigeration performance, and control mode is also the simplest, so cost is minimum in the normal domestic use refrigerator.But this type of refrigerator is because be controlled the restriction of mode, and it is bigger to cause refrigerating fluctuations in indoor temperature, is subjected to the influence of environment temperature and occupation mode to make the temperature drift of refrigerating chamber especially easily; Moreover be subjected to temperature of refrigerating chamber can not reduce to the following restriction of 0 ℃ of degree, and the temperature of refrigerating chamber also can't continue to remain on low-temperature condition, and the result is exactly that this type of refrigerator can't be realized big refrigerating capacity as the multisystem refrigerator.
Summary of the invention
The purpose of this utility model is to overcome above defective, provides a kind of method simple, realizes the single round-robin system cooling system refrigerator of big refrigerating capacity under the precondition of refrigerating chamber accurate temperature controlling.
The technical scheme of refrigerator with high freezing capability of the present utility model is such: it comprises compressor, condenser, device for drying and filtering, refrigerating evaporator, refrigeration evaporator, they are connected to form the loop in turn, refrigerator also comprises control circuit, comprise master control borad in the control circuit, closed circuit is controlled by master control borad, it is characterized in that: the refrigeration evaporator plate is provided with two electrical heating wires, the electrical heating wire of the 15-25 watt that power is bigger is arranged on the refrigeration evaporator, the electrical heating wire of lower-powered 3-10 watt is arranged on refrigerating chamber discharge outlet place, and two electrical heating wires all are connected with master control borad; It also is provided with big refrigerating capacity switch, and switch is arranged on the surface of refrigerator.
When needs are done big refrigerating capacity, press big refrigerating capacity switch, if temperature of refrigerating chamber is lower than 4 ℃, two heater strips are opened heating at the same time, stop the temperature of refrigerating chamber to continue to descend; If the temperature of refrigerating chamber is higher than 6 ℃, two heater strips stop heating simultaneously, by the start-stop of temperature controller control compressor.
For preventing that temperature of refrigerating chamber is lower than 0 ℃; the protection temperature of a compressor is set; compressor quits work when temperature of refrigerating chamber is lower than 1 ℃; heater strip disconnects on the evaporator plate simultaneously; preventing the too fast compressor shutdown deficiency of time that causes of temperature recovery, the heater strip on the compressor and refrigeration evaporator plate works on again when being higher than 3 ℃ when temperature of refrigerating chamber gos up.
Between electrical heating wire on the refrigeration evaporator and the master control borad temperature limit switch is set.
Refrigerator with high freezing capability of the present utility model, simple in structure, can realize big refrigerating capacity rapidly, the quick-frozen ability is very good, can extensive use in the refrigerator field.
Description of drawings
Fig. 1 is the control circuit figure of refrigerator with high freezing capability of the present utility model:
The specific embodiment
Embodiment 1:
It comprises compressor, condenser, device for drying and filtering, refrigerating evaporator, refrigeration evaporator refrigerator with high freezing capability of the present utility model, they are connected to form the loop in turn, refrigerator also comprises control circuit, comprise master control borad in the control circuit, closed circuit is controlled by master control borad, it is characterized in that: the refrigeration evaporator plate is provided with two electrical heating wires, the electrical heating wire of the 15-25 watt that power is bigger is arranged on the refrigeration evaporator, the electrical heating wire of lower-powered 3-10 watt is arranged on refrigerating chamber discharge outlet place, and two electrical heating wires all are connected with master control borad; It also is provided with big refrigerating capacity switch, and switch is arranged on the surface of refrigerator.When needs are done big refrigerating capacity, press big refrigerating capacity switch, if temperature of refrigerating chamber is lower than 4 ℃, two heater strips are opened heating at the same time, stop the temperature of refrigerating chamber to continue to descend; If the temperature of refrigerating chamber is higher than 6 ℃, two heater strips stop heating simultaneously, by the start-stop of temperature controller control compressor.For preventing that temperature of refrigerating chamber is lower than 0 ℃; the protection temperature of a compressor is set; compressor quits work when temperature of refrigerating chamber is lower than 1 ℃; heater strip disconnects on the evaporator plate simultaneously; preventing the too fast compressor shutdown deficiency of time that causes of temperature recovery, the heater strip on the compressor and refrigeration evaporator plate works on again when being higher than 3 ℃ when temperature of refrigerating chamber gos up.Between electrical heating wire on the refrigeration evaporator and the master control borad temperature limit switch is set.
The electrical heating wire power setting is 20 watts on the present embodiment evaporator plate, and the power setting of refrigerating chamber discharge outlet electrical heating wire is 5 watts.When needs were done big refrigerating capacity, two heater strips were opened heating simultaneously when temperature of refrigerating chamber is lower than 4 ℃, stoped the temperature of refrigerating chamber to continue to descend, if the temperature of refrigerating chamber is higher than 6 ℃, two heater strips stop heating simultaneously.For preventing that temperature of refrigerating chamber is lower than 0 ℃; the protection temperature of a compressor is set; compressor quits work when temperature of refrigerating chamber is lower than 1 ℃; heater strip disconnects on the evaporator plate simultaneously; preventing the too fast compressor shutdown deficiency of time that causes of temperature recovery, the heater strip on the compressor and refrigeration evaporator plate works on again when being higher than 3 ℃ when temperature of refrigerating chamber gos up.So promptly can under temperature of refrigerating chamber obtains the prerequisite of fine control, realize long-time compressor operating refrigeration again, thereby reach big refrigerating capacity.If irregular working occurs, temperature limit switch can cut off the heater strip loop automatically, reaches the protection refrigerator and avoids the purpose of fire etc.
