Moreover operation detection switch 128 is under the state (normal condition) of the handle 123 of the described vegetable compartment door 103 of inoperation, and shown in Figure 15 (a), its button 128b leaves from mobile member 124.In addition, as Figure 11 and shown in Figure 13 door switch 129 is packed into as described in the forward position portion of vegetable compartment 107 on the refrigerator main body 101 than the electromagnet 114 on right side more by the position of below.At this moment this door switch 129 also is made of microswitch, its button 129b is forwards stretched out from switch main body 129a and refrigerator main body 101, described vegetable compartment door 103 when utilization is closed is pushed this button 129b, thereby contact not shown in the switch main body 129a is connected and work.Therefore, this door switch 129 plays the effect that the door of closing as detection vegetable compartment door 103 is closed detecting unit.
Then, the control device 130 that constitutes by for example microcomputer shown in Figure 16.This control device 130 plays the effect as the control module of described electromagnet 114 work of control, only represents and illustrate the device relevant with this function among Figure 16.Be that detection signal is respectively by described operation detection switch 128 and door switch 129 these control device 130 of input, control device 130 offers drive control signal the drive circuit 131 that drives described two electromagnet 114 according to these inputs and the control program of storing in advance.
Figure 17 specifically illustrates above-mentioned drive circuit 131, be connected in series by the resistance 134 about the relay tip 133 and 1 (Ω) that will utilize above-mentioned control device 130 work, source power supply E is connected between the AC input terminal of rectification circuit 132, the resistance 136 of smmothing capacitor 135, hundreds of (K Ω) and each coil 118,119 of described two electromagnet 114 and the series circuit between their described each Thermal Cutoffs 137,138 are connected in parallel.
Below, the effect of the refrigerator of above-mentioned formation is described.
At first, when being in the state of closing vegetable compartment door 103, utilize " falling into " structure of closing the door and giving the unit, the castor 121 of container support member 109 is fixed on the most inboard collecting position as above-mentioned.In addition, at this moment the edge part of the stock gateway 107a of the vegetable compartment 107 on the seal washer 110 of vegetable compartment door 103 and the refrigerator main body 101 (dividing plate 127 before comprising) closely contact, and built-in magnet of while is adsorbing this tight state of contact of maintenance.Also have, what at this moment door switch 129 utilized vegetable compartment door 103 closes the execution closing motion, detects closing of vegetable compartment door 103.
If from such state, the user rides over hand on the handle 123 of vegetable compartment door 103 and carries out tractive, then shake hands 123 is the center with fulcrum 125, shown in arrow A among Figure 11, like that forwards rotate, utilize top rearward to push mobile member 124, therefore, the such button 128a of mobile member 124 pressing operation sense switches 128 as described, thereby make operation detection switch 128 closures carry out work, the operation that is used to open vegetable compartment door 103 is detected.
Like this, control device 130 is judged operation detection switch 128 worked (having finished the operation that is used to open vegetable compartment door 103), judge door switch 129 (vegetable compartment door 103 is closed) (the step S1 of Figure 18, the S2) that worked simultaneously, according to this result, to electromagnet 114 (coil 118,119) energising (step S3).
So each magnetic pole of the top portion front end of the magnetic core 115 in the electromagnet 114 and following portion front end demonstrates the magnetic pole same polarity with opposed permanent magnet 111,112 as shown in Figure 14, therefore produce repulsion.Utilize this repulsion, permanent magnet 111,112, so that it is installed in the vegetable compartment door 103 at the back side, by container support member 109, follow stock container 108 to be pushed to the place ahead, on the direction of opening the door, energized.Make container support member 109 and castor 121 break away from above-mentioned " falling into " structure by means of this again, make sealing gasket 110 leave the edge part of the stock gateway of vegetable compartment 107.
Here, the energising of electromagnet 114 is limited in the stipulated time carries out, specifically, for example be limited in about 1 second and carry out (step S4, S5) within the kind.By means of this, on the direction of opening the door, vegetable compartment door 103 is energized, make it only reach the distance that said vesse support member 109 and castor 121 breaks away from 5 required～10mm of above-mentioned " falling into " structure.
Therefore, at this moment, if vegetable compartment door 103 arrives for example user's reasons such as health because of door knob in this energizes distance range, opening of vegetable compartment door 103 by Halfway Stopping, the castor 121 that then makes container support member 109 is owing to " falling into " structure turns back to the most inboard collecting position, by means of this, make vegetable compartment door 103 also can turn back to above-mentioned closed condition.
Moreover, though it is not shown, but control device 130 is also as the door opening times of calculating vegetable compartment door 103 time per units according to the work number of times of operation detection switch 127, the opening door operation frequency detecting unit that detects the opening door operation frequency plays a role, therefore,, limit when being higher than the regulation frequency for 1 inferior in 1.5～2 seconds kinds for example at the opening door operation frequency that detects vegetable compartment door 103, unfavorablely energize opening on the direction of vegetable compartment door 103 with electromagnet 114.
