Abstract
The utility model relates to a refrigerator, more specifically, an electric refrigerator with fans at the side of a evaporator and a condenser. The utility model provides a refrigerator which is equipped with a driving circuit of the fan for adjusting the fan speed according to the frequency of the compressor. The utility model comprises a refrigerating loop. The refrigerating loop is controlled by the CPU of the control unit and comprises an evaporator and a condenser. The evaporator and the condenser are all equipped with fans. The fans are connected electrically with the CPU by the driving circuit of the fans. The driving circuit of the fans comprises a driving motor which is designed as a PG adjustable speed motor. Due to the adjustment of the fan speed according to various refrigerating states of the electric refrigerator, the electric refrigerator of the utility model can enable the fan to do accurate stepless speed change, thereby greatly improving the energy conservation and sound reduction.
Description
Technical field
The utility model relates to a kind of refrigerator, specifically, relates to the other refrigerator that is provided with fan of a kind of evaporimeter and condenser.
Background technology
Refrigerator of the prior art generally all comprises refrigerating circuit, refrigerating circuit is concentrated regulation and control by the CPU in the control module, refrigerating circuit generally comprises compressor, condenser, capillary, magnetic valve, evaporimeter, their formation refrigerating circuits in sequential series, compressor has is set to the speed governing frequency-changeable compressor, can compressor rotary speed be changed and then different refrigerating capacitys is provided by frequency change; In order to increase the heat exchange efficiency of condenser and evaporimeter, usually at condenser and the other fan that also is provided with of evaporimeter, increase the heat exchange efficiency of condenser and evaporimeter by blowing of fan, but the motor in the drive circuit of fan of the prior art generally all is the common electric machine of fixed frequency, be that fan can only turn round under fixing frequency, the cold of evaporimeter and condenser generation can't be maximally utilised the optimized refrigerating efficiency that whole refrigerating circuit is reached like this.
Summary of the invention
The purpose of this utility model is to overcome above defective, provides a kind of drive circuit of fan can adjust the refrigerator of the rotating speed of fan according to the frequency of compressor.
The technical scheme that has the refrigerator of fan of the present utility model is such: it comprises refrigerating circuit, refrigerating circuit is by the CPU regulation and control of control module, refrigerating circuit comprises evaporimeter, condenser, the other fan that all is provided with of evaporimeter and condenser, fan is connected with CPU by fan drive circuit, fan drive circuit comprises drive motors, and fan driving motor is set to the PG buncher.
The control section of PG buncher comprises zero passage detection unit, rotation speed detection unit, electric-motor drive unit.
Refrigerator of the present utility model, because the refrigerating state adjustment that the rotating speed of fan can be different according to refrigerator makes fan can accomplish accurate electrodeless variable-speed, thus energy-conservation and reduce the noise aspect and have greatly improved to refrigerator.
Description of drawings
Fig. 1 is the control structure block diagram of fan of the present utility model.
The specific embodiment
It comprises refrigerating circuit the refrigerator that has a fan of the present utility model, refrigerating circuit is by the CPU regulation and control of control module, refrigerating circuit comprises evaporimeter, condenser, the other fan that all is provided with of evaporimeter and condenser, fan is connected with CPU by fan drive circuit, fan drive circuit comprises drive motors, fan driving motor is set to the PG buncher, the control section of PG buncher comprises the zero passage detection unit, rotation speed detection unit, electric-motor drive unit, the PG buncher that the utility model uses adopts special structural design and technology, use the fire-retardant capsulation material of better thermal diffusivity and insulating properties, the whole plastic packaging of wound stator is made.Motor has low, the characteristics such as vibration is little, moisture resistance good, volume is little, temperature rise is low, good reliability of noise.It is applied in the condenser for refrigerator heat radiation, can regulate motor speed according to the different refrigerating state of refrigerator, realizes stepless speed regulation, thereby refrigerator energy-saving and reduction noise aspect are greatly improved.
The refrigerator that has fan of the present utility model, simple in structure, and very practical, can in utilizing, refrigerator be extensive use of.
