Fig. 7 is the sectional view according to the device for opening of third embodiment of the invention, and the drawer closing state is shown, and Fig. 8 is the sectional view of the device for opening of Fig. 7, the state that drawer is opened is shown, and Fig. 9 is the rearview of the shutoff device of Fig. 7.
With reference to figure 7 to 9, under drawer 200 closing state, drawer door 220 is closed the front end of opening of memory space R, and drawer basket 240 keeps the insertion state in memory space R.
The top that is arranged in the storage container 300 in the drawer basket 240 is closed by container lid 320.By by optionally limiting container lid 320, synchronous to allow container lid 320 with the opening operation of drawer 200, thus be used for opening the device for opening 500 of storage container 300 around container lid 320 and storage container 300 settings.
Describe device for opening 500 now in more detail, this device for opening 500 comprises tooth bar 520, pinion 540 and helical spring 560.
When drawing in or pull out drawer 20, tooth bar 520 and pinion 540 optionally compress or loosen helical spring 560.
Tooth bar 520 flatly is arranged on the basal surface of container lid 320.The tooth of tooth bar 520 is formed on its basal surface.
Pinion 540 is arranged on the side surface of storage container 300, this pinion corresponding with the position of tooth bar 520 and with tooth bar 520 engagement.Therefore, when drawer 200 was mobile forward or backward, pinion 540 moved with respect to the tooth bar 520 that is installed on the container lid 320.
By with the relative motion of tooth bar 520, pinion 540 rotations.There is rotating shaft to be formed on the core of pinion 540.Helical spring 560 is given prominence to and be connected to this rotating shaft along a certain direction.
Helical spring 560 forms by winding up the sheet spring.The rotating shaft of pinion 540 is connected to the core of helical spring 560.Therefore, when pinion 540 rotations, helical spring 560 is wound up, thereby has compression stress.
If necessary, then pinion device 540 can being combined to form by a plurality of gears.In this case, in these gears one moves with respect to tooth bar 520, and is connected to the core of helical spring 560 with another gear of the gears engaged that moves with respect to tooth bar 520.
When drawing in drawer 200, pinion 540 rotates, and moves to the rear end of tooth bar 520 from the front end of tooth bar 610.Thereby helical spring 560 is wound up, to increase compression stress.
That is to say that when drawer 200 was opened fully, helical spring 560 was in the normal condition that does not produce compression stress, and when drawer 200 was closed fully, helical spring 560 was in the state of compression stress maximum.
Needless to say, the compression stress of helical spring 560 can be carried out balance by means of the gravity and the frictional force of drawer 200, not exclusively closes owing to the compression stress of helical spring 560 so that prevent drawer 200.
Simultaneously, there is support component 580 to be arranged on the rear surface corresponding to the memory space R of the rear end of container lid 320, promptly on the side of inner housing 120.Support component 580 is outstanding forward from the rear surface of memory space R, and when being drawn in fully with convenient drawer 200, the rear end of support vessels lid 320, thereby when drawer 200 is drawn in has fully prevented that container lid 320 from being opened by device for opening 500.
Support component 580 is formed by the such elastomeric material of for example rubber, weakens collision when drawing in drawer 200 with box lunch.
The operation of the device for opening of the 3rd embodiment is described below in conjunction with Fig. 7 and 8.
Under drawer 200 closing state, drawer door 220 is closed the open forward end of memory space R, and drawer basket 240 keeps the insertion state in memory space R.The top that is arranged in the storage container 300 in the drawer basket 240 is closed by container lid 320.
In this point, pinion 540 is positioned on the rear end of tooth bar 520, and passes through the rotation of pinion 540, and helical spring 560 is in complete compressive state.Therefore, pinion 540 is tending towards being rotated by the compression stress of helical spring 560, thereby container lid 320 is subjected to power backward.
Yet, because support component 580 is arranged in the rear portion of container lid 320, so restriction container lid 320 is mobile backward.Yet, because the gravity of drawer 200 and frictional force is greater than compression stress 560, so drawer 200 can not be drawn out but maintenance insertion state.
Simultaneously, when the user plans food storage in storage container 300 or when storage container 300 takes out food, he draws drawer 200 to pull out drawer 200 forward.In this point, the storage container 300 that is arranged in the drawer basket 240 is drawn out with drawer 200.
When storage container 300 moved forward, container lid 320 was promoted backward by the compression stress of helical spring 560.When storage container 300 further moved forward, pinion 540 moved and therefore reduces gradually the compression stress of helical spring 560 with respect to tooth bar 520.
The compression stress of helical spring 560 applies, till pinion 540 reaches the front end of tooth bar 520 and promotes container lid 320 backward.When drawer was opened fully and therefore pinion 540 is positioned at the front end of tooth bar 520, helical spring 560 was relax to normal condition.
Therefore, when drawer 200 was opened fully, opened at the top of storage container 300.Then, the user puts into food storage container 300 or takes out food from storage container 300.
Subsequently, when when this draws in drawer 200, the storage container 300 that is arranged in the drawer basket 240 also moves backward.In this point, the state that container lid 320 keeps the supported parts 580 in its rear end to support.
When storage container 300 was mobile backward, pinion 540 was along tooth bar 520 rotations and so compression helical spring 560.
Under the state of drawing in drawer 200 fully, the compression stress maximum of helical spring 560.In this point, owing to frictional force and the gravitational equilibrium of compression stress by drawer 200, drawer 200 can keep the insertion state.
