Abstract
The present invention patent discloses a kind of refrigerator door position detection system, it is characterized in that: in refrigerator door, be fixedly installed gyro sensor, gyro sensor is connected with refrigerator control module by cable, and between gyro sensor and refrigerator control module, carries out the transmission of power supply and detection signal by cable; Export the position detection signal of refrigerator door relative to refrigerator body with gyro sensor, and pass to control module; The refrigerator door switching-state information inscribed when control module judges that also real time record is corresponding according to position detection signal.The present invention is its position of real time record in refrigerator door open-close process, is more effectively carried out temperature control by the motion process Neng Shi refrigerator manufacturer analyzing refrigerator door or is improved user's experience.
Description
Technical field
The invention belongs to parts condition detecting system in refrigerator running, more particularly relate to a kind of refrigerator door position detection system.
Background technology
Refrigerator beat in the course of the work opening door body take or storing food time can cause a large amount of loss of refrigeration capacity, understanding this part loss has larger meaning for design of refrigerator refrigeration system and control system.Such as, different according to different switch gate patten's design intelligent cold compensation schemes etc.But in use, the switch gate of different user custom is different for conventional refrigerator, the method that there is no at present can effectively and reliable recording subscriber switch door information.
Gyroscope is as a kind of position detector tool of maturation, there is structure simple, the feature of small volume, has been widely used in various machinery or electronic product carries out position detection and record, but on refrigerator door on off state, do not carry out the relevant report that detects so far.
Summary of the invention
The present invention is the weak point for avoiding existing for above-mentioned prior art, a kind of refrigerator door position detection system is provided, to can the rotational angle of Real-Time Monitoring refrigerator door or shift position, and then the on off state of record refrigerator door, intelligent cold compensation scheme that can be different according to different switch gate form designs for refrigerator provides foundation.
The present invention is that technical solution problem adopts following technical scheme:
The design feature of refrigerator door position detection system of the present invention is: in refrigerator door, be fixedly installed gyro sensor, described gyro sensor is connected with refrigerator control module by cable, and between gyro sensor and refrigerator control module, carries out the transmission of power supply and detection signal by cable; Export the position detection signal of refrigerator door relative to refrigerator body with described gyro sensor, and pass to described control module; The refrigerator door switching-state information inscribed when described control module judges that also real time record is corresponding according to described position detection signal.
The design feature of refrigerator door position detection system of the present invention is also: while the refrigerator door switching-state information that described control module is inscribed when real time record is corresponding, the refrigerator door switching-state information inscribed when display is corresponding in real time in refrigerator display screen.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention is by detecting rotational angle or the shift position of refrigerator door, frequency and the duration of subscriber switch door can be grasped in real time, the Curve guide impeller that refrigerator design manufacturer carries out refrigeration system is fed back to this, or be directly used in refrigerator control system to carry out cold compensation, thus strengthen the performance of refrigerator.
2, technical solution of the present invention is simple, easy to implement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is control circuit schematic diagram of the present invention;
Number in the figure: 1 refrigerator door, 2 gyro sensors, 3 refrigerator control modules, 4 refrigerator display screens.
Detailed description of the invention
See Fig. 1, Fig. 2, in the present embodiment, refrigerator door position detection system is fixedly installed gyro sensor 2 in refrigerator door 1, gyro sensor 2 is connected with refrigerator control module 4 by cable, and between gyro sensor 3 and refrigerator control module 4, carries out the transmission of power supply and detection signal by cable; Export the position detection signal of refrigerator door relative to refrigerator body with gyro sensor 2, and pass to control module 4; The refrigerator door switching-state information inscribed when control module 4 judges that also real time record is corresponding according to position detection signal.
In concrete enforcement, while the refrigerator door switching-state information that control module 2 is inscribed when real time record is corresponding, the refrigerator door switching-state information inscribed when display is corresponding in real time in refrigerator display screen 3.
When user needs to take or store food is rotated or pulls body, being fixedly installed on gyro sensor in refrigerator door by the displacement signal detected is converted into the signal of telecommunication, refrigerator control module receives this signal of telecommunication, is converted into displacement signal by corresponding for the signal of telecommunication and carry out showing and storing.
The present invention is its position of real time record in refrigerator door open-close process, is more effectively carried out temperature control by the motion process Neng Shi refrigerator manufacturer analyzing refrigerator door or is improved user's experience.
