Description of drawings
Fig. 1 is the block diagram that utilizes the inventive method control refrigerator open process;
Fig. 2 is the close the door block diagram of process of the inventive method method control refrigerator;
Fig. 3 is the block diagram of the magnetic force power assisting device of refrigerator of the present invention.
The specific embodiment
The present invention is that the principle that the same sex of utilizing electromagnet is repelled each other, there is a natural attraction between the sexes realizes the function that power-assisted is opened the door and power-assisted is closed the door.As shown in Figure 3, on the casing of refrigerator and on the door body electromagnet is being housed respectively, two electromagnet end faces are parallel relatively and near (magnetic line of force is corresponding) when refrigerator doors is closed, during work of electromagnet on its coil perfectly straight stream power supply, can change electromagnet pole by changing electric power polarity.When the close end face magnetic pole of two electromagnet is identical, realize that by mutual repulsive force power-assisted opens the door; When two close end face magnetic poles not simultaneously, realize that by the power that attracts each other power-assisted closes the door.
Can on the catch of refrigerator, be provided with the action of sensing element (as microswitch, soft-touch control etc.) impression sliding door, when the people pulls, sensing element can be sent into enabling signal control device (as SCM system, control circuit etc.), and the door switch signal in the refrigerator body is also sent into control device (with the on off state of decision gate) simultaneously.Control device resolves back accessory drive (as relay, controllable silicon etc.) and makes electromagnet energising, outage or change energising polarity.
Electromagnet shown in Figure 3 can adopt direct current supply, promptly can change the magnetic pole of electromagnet by the power supply polarity of control device change electromagnet.
When refrigerator doors is in closed condition, if any the sliding door action, then the sensor that is set together with handle apparatus sends signal to control circuit, two that can make casing electromagnet and door body electromagnet near end face generation same pole, overcome an envelope suction by the repulsive force between same pole, realize the function that power-assisted is opened the door.The control flow that power-assisted is opened the door as shown in Figure 1;
Being arranged on door switch in the casing and being used to detect whether refrigerator doors closes and control cabinet intraoral illumination lamp, is the reliability of guaranteeing the door switch action, and the door switch of current refrigerator is that door switch just moves when refrigerator doors is in low-angle and opens mostly.If door can not be closed (leaving little gap) fully at closing time, this moment, door switch was in the position of closing the door, and at this moment case intraoral illumination lamp does not work, and the open alarm function of computer refrigerator is also inoperative, and the user is not easy to find that refrigerator doors can not be closed fully very much.
The present invention can guarantee in the process of closing the door, and when door switch has been in closed condition, but Men Wei can make the calutron energising produce the power-assisted of closing the door by control device when closing tight, and the gap that occurs not in place prevents to close the door.Promptly by receiving the signal of refrigerator door open-close, making two of casing electromagnet and door body electromagnet before refrigerator doors is closed fully is opposed polarity near end face, quickens closing of door by the attraction between different magnetic poles, realizes the function that power-assisted is closed the door.The control flow that power-assisted is closed the door as shown in Figure 2;
In said structure, be arranged on the casing and the door body on magnetic devices can adopt calutron simultaneously, also the electromagnet on door body or the casing can be substituted with permanent magnet.
Be to improve the power-assisted effect, can the diverse location of refrigerator body and door body arrange simultaneously many to symmetrically arranged electromagnet to strengthen the power-assisted effect.
