Abstract
The utility model relates to a frequency conversion refrigerator, more specifically a control device for a frequency conversion refrigerator. The utility model provides an integral type control device for a refrigerator having the advantages of simple structure and the full use of resources. The utility model comprises a circuit board, wherein the circuit board is provided with a drive circuit for a frequency conversion compressor of the refrigerator. The utility model also comprises a control circuit of a refrigerating circuit of the refrigerator. With the use the control device for a refrigerator of the utility model, the control process of the refrigerator is easier, and the structure is compact; moreover, the resources are saved, the cost is reduced and the labor intensity is reduced.
Description
Technical field
The utility model relates to a kind of frequency conversion refrigerator, specifically, relates to a kind of control device of frequency conversion refrigerator.
Background technology
Frequency conversion refrigerator of the prior art is provided with compressor drive mostly separately, and compressor drive generally all has only the driven compressor function, that is to say that also needing the another one controller is that master control borad signals to driver and could control the operation of compressor or stop; Do not have the input of external control signal, the driver of frequency-changeable compressor itself is with regard to cisco unity malfunction, and this driver of compressor and controller separated structures make refrigerator production more loaded down with trivial details, increased product cost and labour intensity.
Meanwhile, this driver and controller separated structures, driver and master control borad must be respectively arranged with CPU and the power supply of oneself, and driver and master control borad all must be provided with corresponding input or output unit, have so also caused certain wasting of resources.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, provides a kind of simple in structure, resource to use sufficient integral type refrigerator control device.
The technical solution of the utility model is such: it comprises a circuit board, refrigerator frequency-changeable compressor drive circuit is arranged on the circuit board, the control circuit that also comprises refrigerator refrigeration loop, circuit board is provided with compressor drive circuit and shared power supply, the CPU of control loop, also comprise compressor control unit, sensor interface, peripheral hardware control interface, wherein CPU is connected with driven compressor part, sensor, solenoid valve controller respectively.
In order to realize other function of refrigerator, man-machine interface also is set, the last connection of CPU eeprom memory on the CPU.
Use control device of refrigerator of the present utility model, not only make the control procedure of refrigerator simpler, compact conformation, and saved resource greatly, and reduced cost, alleviated working strength.
Description of drawings
Fig. 1 is the block diagram of the frequency-changeable compressor driver of prior art;
Fig. 2 is a control device of refrigerator of the present utility model.
The specific embodiment
As shown in Figure 2, circuit board of the control device of refrigerator of the present utility model, refrigerator frequency-changeable compressor drive circuit is arranged on the circuit board, the control circuit that also comprises refrigerator refrigeration loop, shared power supply, CPU mutually is set on the circuit board, also have compressor control unit, sensor interface, peripheral hardware control interface in addition, wherein CPU is connected with compressor control unit, sensor, solenoid valve controller respectively.Man-machine interface also is set on the CPU, can connect man-machine communication's device in the man-machine interface, this control device of refrigerator just can be by compressor to refrigerator itself, sensor, magnetic valve is controlled simultaneously, do not need to resemble and independent driver is set the refrigerator of the prior art and drives, can carry out the function of original controller and driver simultaneously, simultaneously, be connected with eeprom memory on the CPU of this control device, because the memory space of eeprom memory is bigger, thereby the control parameter of different refrigerators can be stored among the EEPROM, control program can operate in optimum state according to the control of the parameter among EEPROM refrigerator; Simultaneously, sensor of this control device and solenoid valve controller directly are connected on the CPU, CPU just can be according to what of the sensor that inserts, automatically judge what warm areas refrigerator has, thereby the electromagnetic valve switch of control varying number and the rotating speed of compressor make the temperature of each warm area and temperature fluctuation be controlled at optimum state.Like this, this control device of refrigerator is equivalent to refrigerator master control borad of the prior art and compressor drive are arranged to for integral structure, has saved the limited space of refrigerator inside, and has saved material; And during original branch body structure, oneself input, output device all will be set between master control borad and the driver, compressor drive of the present utility model because and becoming one of master control borad structure, so do not need special input, output unit, so circuit is simpler and more direct and control is more direct.
Control device of refrigerator of the present utility model can be extensive use of in the production field of refrigerator.
