In recent years, great changes will take place for food life, buys the life of the cooking food of every day from concentrating nigh food supply retail shop, and the food storage of all usefulness generalizes in refrigerator to for example once buying in countryside large supermarket etc.In addition, correspondence has increased the situation of the utilization of frozen food, and the large-scale refrigerator that surpasses 400 liters of capacity in the family is generally also universal.
Yet the amount of the food of depositing along with the maximization of refrigerator also increases, and stores for example food more than the 20kg at refrigerating chamber or vegetable compartment, so exist the power of the door of opening vegetable compartment or refrigerating chamber to become heavy and so on problem.
Particularly when beginning to open, except the load of track of opposing drawer, also add the power that is pulled away from the magnetic seal spare that is adsorbed on the refrigerator main body, the power of opening door becomes heavy especially, so the little people of hand-power for person etc. at advanced age opens refrigerator and has become burden.
In addition, with regard to refrigerator, if close at closing time the words of not severely punished state in the half-open door of what is called, then produce following problem: cooling gas leakage is lost refrigerator functions to the outside, and the reduction of the electricity charge more piece of cost energy effect, the quality badness of the food of being stored simultaneously has again, the outer extraneous gas of refrigerator enters dewfall in the refrigerator, and water droplet is attached in the refrigerator.
So, the invention provides a kind of refrigerator the drawer door drive unit its can reduce refrigerator drawer door tensile force and can trippingly door be opened, and can automatically door be closed, thereby can improve energy-conservation effect from the half-open door of what is called state.
Yet the door for refrigerator in order to prevent the leakage of cold air at closing time, is provided with the seal of magnetic adsorption type in complete all scopes of door, absorption around the peristome of magnet and main body when door is closed.And general to constitute be to possess close mechanism, this close mechanism when door is closed arrive for example be closed to about opening residue 50mm near the buttoned-up status after, utilize the power of spring etc. to introduce door.Owing to be this structure, so occasion at the door of opening refrigerator, at the beginning of opening, need to add the tensile force of the attraction of magnetic seal spare, spring that close mechanism had, in addition will comprise door and leave in a storing containers that is wholely set in food accelerate to the speed drawn back for example to the power of the summation of the needed acceleration in the per second 200mm left and right sides at interior whole drawer from halted state, so, particularly in the occasion of store food in large quantities, the power that pulls the door open is the first maximum power.After about Men Lakai 10mm, because the absorption of magnetic seal spare and main body is pulled away from, so the power that pulls the door open is second power of the summation of the tensile force of the spring that close mechanism had and acceleration that drawer is quickened.If the scope that gives tractive force because of close mechanism to closing direction to for example scope of 50mm, is necessary in this scope second power from the closed condition of door then.Then, continue opening action, after door was opened to more than the 50mm, close mechanism was inoperative, so the power that is applied on the drawer only is acceleration and the frictional force that slide rail produced that is used to make drawer slide, be the opening action that the 3rd power just is enough to carry out drawer therefore with minimum power.Here, opening the structure that moment about 50mm reaches the drawer opening speed if make, then the 3rd power is only for the opposing frictional force that slide rail produced is just enough, in a word, and only with comparing first power, just being enough to carry out opening action than smaller the 3rd power of second power.
When opening the drawer of refrigerator, as described above, have when beginning to open heavy especially, and after for example opening to a certain degree about 50mm with the just enough characteristics of some power.In the present invention, provide a kind of be suitable for aforesaid when pulling out the drawer of refrigerator the refrigerator drawer door drive of the characteristic of applied force.
On the one hand, though the speed of the door when opening action is arranged, in the moment that is pulled away from magnetic seal spare owing to begin action from halted state, so this scope promptly in the scope of first power speed minimum also passable.On the other hand, when drawer is continued to be opened to the scope of second, third power, if quicken gradually and become high speed and move like that, then because the action when approaching the user with hand traction drawer door with the speed of door, institute thinks the nature action, thereby is well suited for.In the present invention, also provide a kind of refrigerator drawer door drive that is suitable for aforesaid speed characteristics when pulling out the drawer door of refrigerator.
Also have, when opening drawer door, continue to apply tensile force in the structure that door is opened fully, for example, in the user's that stands in front of the door occasion, perhaps be placed with the occasion of article, if when drawer door is met these, also continue to apply tensile force and do not stop, so danger close.Therefore, not to continue to apply driving force when opening drawer door, but only applying driving force in the short scope that begins to open, the frictional force that produces because of slide rail of the initial velocity that obtains in the scope of driving force is slowed down and the action of the so-called inertia of utilization that stops is safe gradually then.
Have again, in the be failure to actuate occasion of situation of door drives such as power failure, because with manually opening and closing drawer, so wish it is following structure, even promptly be provided with the refrigerator drawer door drive, do not hinder with manually opening and closing the action of drawer door or applying unnecessary load and make the action dull yet.

Opening action is described.
Detailed action when secondly, using Fig. 6 to open refrigerating chamber door 5a to utilizing door drive 10 of the present invention describes.Fig. 6 is the figure of the action of expression door drive 10 of the present invention when opening refrigerating chamber 5, and is (a) same with Fig. 3, the state that expression refrigerating chamber 5 is being closed, and show by with (b) (c) (d) serve as that order is moved the action of opening refrigerating chamber 5 (e).Swivel plate 19 rotates freely around driving shaft 18, and web 16 moves supported freely to the diagram left and right directions, and web 16 is provided on the refrigerating chamber 5, so the opening action of refrigerating chamber 5 is represented in web 16 action of direction left.Here, the datum line of the position of the diagram left end of the web 16 in the state that expression refrigerating chamber 5 is being closed is expressed as and introduces position 34.
In (b) state, swivel plate 19 is to the rotation of arrow C CW direction, and the first drive pin 20a contacts with the first bearing plane 21a, web 16 is produced the power of arrow 23a direction.At this moment,, the first drive pin 20a is the position apart from r1 shown in Figure 3, so the power that passes to web 16 from the first drive pin 20a then is T/r1 be made as T as if the torque that will impose on driving shaft 18 because being positioned at apart from driving shaft 18.By this power is set for the power quickened than the introducing power of the power of the magnetic seal spare that is pulled away from refrigerating chamber 5 and closure member 13 and to the quality of the deadweight of refrigerating chamber 5 and stored food make a concerted effort big, thereby be pulled away from the absorption of magnetic seal spare, web 16 to illustrating left to moving, begins to open refrigerating chamber 5 with refrigerating chamber 5.
And under (c) state of arrow C CW direction rotation, the second drive pin 20b contacts with the second bearing plane 21b at swivel plate 19, and the first drive pin 20a leaves from the first bearing plane 21a.Promptly, the second drive pin 20b is positioned at apart from driving shaft 18 and is the position apart from r2 shown in Figure 3, and r2＞r1, the second drive pin 20b is the distance of driving shaft 18 than the first drive pin 20a from pivot, so it is fast to rotate circumferential speed.Therefore behind the second drive pin 20b and the second bearing plane 21b butt, the first drive pin 20a leaves from the first bearing surface 21a.Under this state, the second drive pin 20b contacts with the second bearing plane 21b, gives the power of arrow 23b.At this moment, being the position apart from r2 shown in Figure 3 because the second drive pin 20b is positioned at apart from driving shaft 18, then is T/r2 so pass to the power of web 16 by the second bearing plane 21b from the second drive pin 20b be made as T as if the torque that will impose on driving shaft 18.Though this power than under the state shown in Fig. 6 (b) to impose on the power of web 16 by the first drive pin 20a on arrow 23a direction little, but because magnetic seal spare is pulled away from, so this moment, applied force was set at than the introducing power of closure member 13 and further getting final product greatly with joint efforts the power of the quality acceleration of the deadweight of refrigerating chamber 5 and the food deposited, web 16 to illustrating left to moving, continues the opening action of refrigerating chamber 5 with refrigerating chamber 5.
Then, under (d) state of arrow C CW direction rotation, the 3rd drive pin 20c contacts with the 3rd bearing plane 21c at swivel plate 19, and the second drive pin 20b leaves from the second bearing plane 21b.
Promptly, the 3rd drive pin 20c is positioned at apart from driving shaft 18 and is the position apart from r3 shown in Figure 3, and r3＞r2 is because the 3rd drive pin 20c is the distance of driving shaft 18 than the second drive pin 20b from pivot, so it is fast to rotate circumferential speed.Therefore, behind the 3rd drive pin 20c and the 3rd bearing plane 21c butt, the second drive pin 20b leaves from the second bearing surface 21b.Under this state, the 3rd drive pin 20c contacts with the 3rd bearing plane 21c, gives the power of arrow 23c.At this moment, being the position apart from r3 shown in Figure 3 because the 3rd drive pin 20c is positioned at apart from driving shaft 18, then is T/r3 so pass to the power of web 16 by the 3rd bearing plane 21c from the 3rd drive pin 20c be made as T as if the torque that will impose on driving shaft 18.
Though this power than under the state shown in Fig. 6 (c) to impose on the power of web 16 by the second drive pin 20b on arrow 23b direction also little, but because refrigerating chamber 5 has carried out opening action and has moved to the direction of arrow 23c, so refrigerating chamber 5 has container and comprises the momentum of stored food in the speed correspondence of interior deadweight, pass to the power of the 3rd bearing plane 21c of web 16 by this momentum with from the 3rd drive pin 20c, the tensile force of opposing closure member 13 and can further continue opening action.
Then, under (e) state of arrow C CW direction rotation, represented the state that the 3rd drive pin 20c leaves from the 3rd bearing plane 21c basically at swivel plate 19.Is that the scope that web 16 is subjected to from the power of drive pin 20 is that what is called is opened the driving scope from the state of Fig. 6 (a) up to the scope of the amount of movement 33 of the web 16 of the state that reaches Fig. 6 (e).Here, the amount of movement 33 of this web 16 is set at and promptly closes reheat range than the introducing amount of closure member 13 and be advisable greatly.For example be 40mm promptly, if the introducing stroke of the closure member of scope is closed in conduct, the amount of movement 33 of web 16 is 50mm, even then web 16 stops in the position shown in Fig. 6 (e), promptly refrigerating chamber 5 stops, and the refrigerating chamber of just having opened 5 can not be closed because of closure member 13 yet.But, if refrigerating chamber 5 is more opened than the state of Fig. 6 (e) and web 16 to the diagram left to the words that move, though then web 16 is not subjected to the driving force from drive pin 20, but because refrigerating chamber 5 has the speed to arrow 23d direction, so can continue opening action till the friction load that is had because of slide rail 11 slows down gradually and stops.Owing to move like this, so the opening of refrigerating chamber 5 is bigger than the amount of movement 33 of web 16.
As mentioned above, because when being implemented in the opening action that carries out refrigerating chamber 5 is not the driving force that continues to apply to opening direction, but only in the short scope that begins to open, apply driving force, thereafter, the action that the translational speed that obtains in the scope of driving force reduces gradually and stops because of frictional force that slide rail had, so, in the user's that stands in front of the door occasion or the occasion of having placed article, can not be subjected to even run into refrigerating chamber 5 yet, thereby be safe to the driving force of opening direction.
As mentioned above, when closed condition begins to open refrigerating chamber 5, be configured in from the driving shaft 18 first nearest drive pin 20a and also drive by releasing web 16, export bigger power and be pulled away from magnetic seal spare with low speed, then, drive by being arranged on to release web 16 and export moderate power with the medium speed than the first drive pin 20a, the second drive pin 20b also far away, thereby the introducing power of opposing closure member 13 continues opening action and refrigerating chamber 5 is quickened, next, release web 16 by being arranged on from driving shaft 18 the 3rd drive pin 20c also far away than the second drive pin 20b, can further quicken by high-speed driving though power is little refrigerating chamber 5, carry out the opening action of refrigerating chamber 5 reliably, thus all right.
In structure of the present invention, drive pin 20 contacts with web 16 and gives the position of driving force, observe from driving shaft 18, what be in relative refrigerating chamber 5 opens the roughly rectangular direction of direction 23, so the rotating speed of the speed of opening direction 23 of drive pin 20 and swivel plate 19 and proportional to the brachium of drive pin 20.Like this, and use rotating cam in the prior art, door only released to the structure to the change in radius amount of the above-mentioned cam and the contact point of door portion compared, can be easily will release speed 23 high speeds.Owing to be this structure, so can realize only applying driving force in the short scope of opening beginning, the opening speed 23 that obtains in the scope of driving force slows down gradually because of the frictional force that slide rail had and the action that stops is good then.
After utilizing above-mentioned action to open refrigerating chamber 5, swivel plate 19 further continues the rotation to the CCW direction, and the state that reaches Fig. 6 (a) stops the rotation.In addition, certainly, this moment, web 16 was not in the position shown in Fig. 6 (a), owing to refrigerating chamber 5 is opened, so be in the state that moves to the diagram left.
Such as described above, in door drive of the present invention, swivel plate 19 is behind the opening action that has carried out refrigerating chamber 5, proceed to unidirectional rotation and the words that turn around, can return the state when closing refrigerating chamber 5, promptly owing to the former point range that can turn back to Fig. 8 explanation, so the situation that returns to initial point with high speed is better.Suppose that swivel plate 19 is not to the rotation of direction but carried out stopping to rotate round about because of an end behind the opening action of refrigerating chamber 5 words of the structure that returns to former point range, then as the present invention as can be known, with compare to the rotation of a direction, the time that then is back to former point range is too much.
Calculating to opening describes.
The opening of door during 5a of utilizing door open/close machine of the present invention to open refrigerating chamber 5 described.
Figure 18 is the figure of the relation of the speed of the refrigerating chamber of explanation when opening refrigerating chamber 5 and opening, opening action by refrigerating chamber door 5a illustrated in fig. 6, in the scope of amount of movement 33, refrigerating chamber door 5a is opened by means of press surface 21 applies the power of opening direction from drive pin 20 by door drive 10.Here, refrigerating chamber 5 has speed V in the moment (5 ') of opening with amount of movement 33, thus because of inertia continues to open, and there is not driving force in inertia opening 74 intervals, and the position that finally is opened to maximum opening 73 of slowing down gradually (5 ") and stop.
Here, if will comprise stored food is made as m at the total quality of interior refrigerating chamber door 5a, then the locational kinetic energy E of amount of movement 33 is
E=(m * V 2)/2 (formula 1)
Here, if the coefficient of friction that slide rail 11 is had is made as μ, acceleration of gravity is made as g, then the frictional force F that is produced by slide rail 11 is
F=μ * m * g (formula 2)
Be equivalent to frictional force F and rubbed and the distance L that moves is the long-pending of inertia opening 74 by the ENERGY E 2 of frictional force consumption, so,
E2=L * F=L * μ * m * g (formula 3)
Here, if the refrigerating chamber kinetic energy that begins to have is most all consumed by friction to stopping, then owing to E=E2, so
(m * V 2)/2=L * μ * m * g (formula 4)
Both sides are divided by m,
(V 2)/2=L * μ * g (formula 5)
So with (formula 5) distortion, inertia opening 74 (being L) is expressed as
L=(V 2)/(2 * μ * g) (formula 6)
Promptly, by formula 6 as can be known, it doesn't matter for the quality m of inertia opening 74 and refrigerating chamber 5, depend on the coefficientoffriction of slide rail and be that drive pin 20 deviates from mutually with press surface 21 at amount of movement 33 speed V constantly, the driving force of opening direction that is delivered to web 16 from swivel plate 19 disappears, and begins to open speed constantly with inertia.
Here how all, the quality m of refrigerating chamber 5 is different because of the amount of stored food certainly, no matter but wish the amount almost fixed of maximum opening 73 food of the refrigerating chamber door 5a of the electronic occasion of opening refrigerating chamber but then.That is, the coefficientoffriction of slide rail 11 is fixed values of being determined by slide rail, wants to make maximum opening 73 almost fixed, preferably reduces the change of speed V because of amount of food.So, the speed that it is desirable to make driving mechanism 15 than enough greatly, the change that makes the load torque that imposes on motor 24 reduces and reduce the structure of the change of rotating speed, for example preferably makes speed reducing ratio more than 1/100.By increasing speed reducing ratio, make the output torque of motor 24 have bigger affluence amount, so can reduce change, thereby can reduce change, thereby be fit to because of the maximum opening 73 that how much causes of amount of food because of the rotating speed of the motor that how much causes 24 of amount of food.
Contrast with cam structure is described.
Speed V when refrigerating chamber 5 is only opened amount of movement 33 and utilized inertia to move, as utilize Fig. 6 (e) illustrates, owing to be the speed that the 3rd drive pin 20c moves to the direction of opening direction 23c, so proportional with the rotating speed of swivel plate 19, and the distance of the pivot of the contact point 75c of the 3rd drive pin 20c and the 3rd press surface 21c and driving shaft 18 is that radius of turn r is proportional.Here, as at Fig. 6 (d) to as shown in Fig. 6 (e), the position of contact point 75c (75d among Fig. 6 (e)), with pivot be driving shaft 18 be positioned at when being benchmark with open direction 23 roughly the direction of quadrature illustrate above, so web 16 to the translational speed of opening direction 23 and the 3rd drive pin 20c when driving shaft 18 rotates to circumferencial direction speed circumferential speed about equally.
Secondly, in order to compare, use Figure 13 to describe for the opening speed of the structure of using known cam all the time with relevant above-mentioned illustrated structure.In Figure 13, cam 76 is supported with axle along the direction rotation of direction of rotation 80 freely around pivot 77, and is the writing board shape of periphery 78 off-centre.Be provided with cam receiving plate 79 contiguously with the periphery 78 of cam 76, cam receiving plate 79 is arranged on the refrigerating chamber 5, push cam receiving plate 79 to arrow 81 directions and move to direction of rotation 80 rotations by cam 76, so refrigerating chamber 5 is opened to the diagram left with cam receiving plate 79.At this moment, cam 76 contacts at contact point 86 with cam receiving plate 79 ' when the position of 76 ' shown in the with dashed lines.If represent the words of the circumferential speed of contact point 86 at this moment with arrow 83, then cam receiving plate 79 ' is that the arrow 83 of circumferential speed promptly is equivalent to the part of arrow 84 at the projection composition of opening direction to the translational speed of opening direction in diagram left side, is that the part of arrow 85 produces cam 76 and lobe plate 79 to slide to the projection composition with the direction of opening the direction quadrature.Like this, used the variable quantity of radius of the contact point of the cam 76 that only produces by cam 76 rotations to the speed of opening direction of occasion of structure of cam and cam receiving plate 79, so not only the circumferential speed than cam 76 is little for cam receiving plate 79 suffered speed, and between cam 76 and cam receiving plate 79, produce to slide, thereby be easy to produce problems such as the wearing and tearing of cam 76 and cam receiving plate 79 and fricative.
Have again,, have only the function that door is pushed to left for the structure of having used cam shown in Figure 13, and the function of door not being shut.
Closing motion is described.
In the occasion of having closed refrigerating chamber 5, refrigerating chamber 5 is not closed to magnetic seal spare 14 and is sucted for a certain reason sometimes, and having the gap between magnetic seal spare 14 and refrigerator main body 1 is so-called half-open door state.The action of the door drive 10 under so half-open door state is described with Fig. 7.
Fig. 7 is the figure of the action of expression door drive 10 of the present invention when closing refrigerating chamber 5, (a) be that expression refrigerating chamber 5 is not closed, the diagram left end of web 16 is in than introducing position 34 and has only moved the state that the driving scope is an opening 35 of closing that can carry out closing motion.On refrigerating chamber 5, be provided with closure member 13, usually refrigerating chamber introduced being closed, but the action that seldom produces slide rail 11 hangs up because of a part of food by the introducing power of closure member 13, or some reason temporary transient sluggish (having some setbacks) and situation about can not introduce.
Here, if with swivel plate 19 around driving shaft 18 to arrow C W direction rotation, the face that reverses 22 butts in the 3rd drive pin 20c and diagram left side then, this face 22 that reverses is faced with bearing plane 21 of web 16.The state that Fig. 7 (b) expression makes swivel plate 19 be further rotated to arrow C W direction, but since web 16 pushed to arrow 36 directions by the 3rd drive pin 20c and move, so the diagram left end of web 16 moves to introducing position 34 always.Position shown in this Fig. 7 (b) represents that magnetic seal spare 14 is adsorbed onto that refrigerating chamber 5 is in the position of closing fully on the refrigerator main body 1.Then, make swivel plate 19 be in the state of Fig. 7 (c) to the rotation of arrow C CW direction, stop up to rotating to same position shown in Figure 3.
By action as described above,, refrigerating chamber 5 is in the state of so-called half-open door even not closing fully, by swivel plate 19 is rotated to the rightabout with the occasion of opening refrigerating chamber 5, also can apply the power of closing refrigerating chamber 5 directions and it is closed, thereby prevent that half-open Men Erwei is good web 16.
As illustrated just now, though the power when opening refrigerating chamber 5 need be pulled away from the above power of summation of the introducing power of the power of magnetic seal spare 14 and closure member 13, but owing to when closing, do not need to be pulled away from the power of magnetic seal spare 14, and produce the introducing power of closure member 13, so the words that the power of closing that is applied by door drive 10 of the present invention is compared with the power of opening are that very weak power is just enough.
According to present embodiment,, push the structure of the face that reverses 22 of web 16 from driving shaft 18 the 3rd drive pin 20c farthest owing to be formed in when closing refrigerating chamber 5, so, the driving torque that dummy adds to drive pin 18 is identical when opening, and the power of closing is compared with tensile force, also only little r1/r3 and be good.Like this, even just in case between refrigerating chamber 5 and refrigerator main body 1, accompany under the situation of finger, so because the little safety of folder power.
Have, making closing velocity is that the action that low speed is slowly closed is safe again.Therefore, preferably make closing motion than the action of opening refrigerating chamber 5 low speed more.
Here, can close the opening 35 of refrigerating chamber 5 according to Fig. 2 explanation and promptly close the driving scope, opening 35 is that thickness gate 71 is little than the thickness of the door body 5a of the front that forms refrigerating chamber 5 preferably.This be because, if make opening 35 bigger than thickness gate 71, might be between the door gap that produces between the door of refrigerating chamber 5 and vegetable compartment 6 or switch room 3 when then beginning to introduce refrigerating chamber 5 72 clamp finger etc., but if opening 35 is littler than thickness gate 71, then can not clamp finger, so security is higher.
Manual activity is described.
Secondly, use the optimum position of the swivel plate 19 of Fig. 8 when being in refrigerating chamber 5 closing state to describe.In Fig. 8, consistent with introducing position 34 with the diagram left end of the illustrated web 16 of solid line, refrigerating chamber 5 is in pent position.In refrigerator,, but use the situation that pulls out refrigerating chamber 5 because of certain reason user in addition even possess the such door drive of the present invention 10.Perhaps, hinder the occasion of akinesia etc. for some reason at door drive 10, the user wishes to use manual freely openable.With the occasion that manually opens and closes, it is desirable to door drive 10 is the structures that do not produce the phenomenon that hinders user's manual activity or action dull etc. when opening and closing refrigerating chamber 5 so.
If the user pulls out refrigerating chamber 5 with the state of manually closing from refrigerating chamber 5 and opens, the web 16 that then is arranged on the refrigerating chamber 5 moves the position that is in dotted line to the diagram left side.In the position of dotted line, additional to each symbol ' represent.Here, swivel plate 19 is in the position of representing with the solid line of Fig. 8, in this position, at the front end that is arranged at the second bearing plane 21b on the web 16 promptly between the second front end 37b and the first drive pin 20a gapped 38, when if web 16 moves to the diagram left, there are discontiguous position relation in the second front end 37b and the first drive pin 20a, and then user's web 16 when pulling out refrigerating chamber 5 does not contact with drive pin 20, thereby can freely pull out refrigerating chamber 5 and open.
Secondly, swivel plate 19 is in the position 19 ' of dotted line, in this position, be arranged between the first front end 37a on the web 16 and the 3rd drive pin 20c gapped 39, if when moving, there are discontiguous position relation in the first front end 37a and the 3rd drive pin 20c to web 16 to the diagram left, then the user is when pulling out refrigerating chamber 5, web 16 does not contact with drive pin 20, thereby can freely pull out refrigerating chamber 5 and open.
As above-mentioned illustrated, in order not contact with drive pin 20, as long as link in the angular range that the line of the driving shaft 18 and the first drive pin 20a is in former point range 40 at user's web 16 when manually opening and closing refrigerating chamber 5.Therefore,, it is desirable to set for swivel plate 19 and be in above-mentioned former point range 40 in the occasion of closing refrigerating chamber 5, also good with manually opening and closing usability.The angular range of such swivel plate 19 is called in the present invention is in former point range.
Structure to control system describes.
Secondly, use Fig. 9 that the structure of the control system that is used for control gate drive unit 10 is described.Fig. 9 is the calcspar of expression control system structure.
Possessing the operation display part 7 of opening switch 8 supresses the user and transfers signal to control substrate 41 when opening switch 8.Be arranged on the driving mechanism 15 on refrigerating chamber 5 and the vegetable compartment 6 motor separately 24, detect the rotation testing agency 32 of the position of rotation of driving shaft 18, and the door test section 17 of the open and-shut mode of detecting gate with control substrate 41 and be connected.
92 expressions be arranged on the door body 6a of door body 5a or vegetable compartment 6 of refrigerating chamber 5, by the switch main body of opening switch of user's operation, it will be narrated in detail in the back.
The needed electric power of the driving of door drive 10 and control circuit 41 is supplied with by power supply 42.Rotation testing agency 32 can be the variable resistance that its resistance value changes by the rotation of axle as an example, or detects the detection means of microswitch etc. of position of rotation of the regulation of axle.
Second the test section 17b of opening below the 35 whether opening of the door that door test section 17a possesses first a test section 17a that whether closes fully of detection refrigerating chamber 5 and detects refrigerating chamber 5 is being stipulated.For example, can be to be provided in the magnet on the door and to be provided in Hall element on the refrigerator main body 1, or the detection means of microswitch etc.
On operation display part 7, also can be equipped with and inform member 70, to be used for door is in the advisory user of half-open door state.The example that this informs member 70 can make siren pipe, and perhaps makes lamp light or neglect and brightly goes out suddenly.
Describe opening control.
Utilize Figure 10 that the order of opening control when opening refrigerating chamber 5 is described.Figure 10 is the flow chart of opening control sequence when opening refrigerating chamber 5.
If beginning opening action (square 43), if control circuit 41 detect operated the situation of opening switch 8 by the user after, control circuit 41 is motor 24 energisings (square 47), and makes swivel plate 19 rotations.The direction of rotation of the swivel plate 19 of this moment is the CCW direction in Fig. 3, if swivel plate 19 rotations, then as illustrated in fig. 6, web 16 is driven pin 20 pushings and refrigerating chamber 5 is opened.Motor 24 continues rotation, if confirm the situation (square 48) that the position of rotation by rotation testing agency 32 detected swivel plates 19 has entered former point range 40, then makes motor 24 stop (square 49) and finishes a series of opening action (square 50).
The voltage application method is described.
Here, to motor energising (square 47) voltage application method when beginning to open refrigerating chamber 5 is described.Rated voltage sharply increases when motor is switched on, and at the moving dash current of the coil midstream of motor, the maximum output torque of motor output begins rapid rotation from halted state.Therefore, when beginning to open, refrigerating chamber 5 can carry out maximum acceleration, being swift in motion and opening with sudden force when beginning to open.
So, wish voltage is switched on as follows with changing, that is: with motor 24 energisings (square 47) time, not that rated voltage sharply increases, but at the beginning of energising, for example apply the low-voltage of 1/2 degree of rated voltage, behind beginning driving gate drive unit 10, when opening refrigerating chamber 5 voltage is increased gradually, and before the state of (c) in opening action shown in Figure 6 to (d), the speed to opening direction that is delivered to web 16 from drive pin 20 become maximum, voltage is risen reach rated voltage.Like this, increase gradually by making voltage, the action when refrigerating chamber 5 begins to open becomes slowly, so can not open with sudden force, can open action with high utmost point sense.
Have, behind the state that has passed through Fig. 6 (e), swivel plate 19 continues after the rotation of CCW direction, and stops after rotating to the position shown in Fig. 6 (a) again, but after refrigerating chamber 5 is opened, is not in the state that swivel plate 19 is not applied load and dally.Therefore, also can make the voltage ratio rated voltage that imposes on motor 14 low behind the state that has passed through Fig. 6 (e), the rotating speed that makes motor 24 is a low speed.Like this, by making the low speed that rotates to be of motor 24, have the effect that can reduce noise that motor 24 produces or vibration and realize quiet action.Have again,, stopped, so suitable thereby stop the precision raising by make motor 24 stop Shi Buhui with low speed rotation though will make swivel plate 19 stop at former point range 40 illustrated in fig. 8 reliably.
Construction of switch is described.
Secondly, one example of the construction of switch the when user opens indication to switching mechanism of the present invention is described.Figure 19 is the partial sectional view that possesses the refrigerator of door open/close machine of the present invention, and Figure 20 represents the enlarged drawing of S portion shown in Figure 19.When S portion represents to constitute the top edge of front door body 5a of refrigerating chamber 5 and door and closes with the framework 87 of main body 1 side of a butt near.
Upper end at door body 5a is provided with button 88, and this button 88 is more outstanding than door body 5a.Be provided with pressing lever 89 in the inboard of button 88, button 88 and pressing lever 89 run through a body 5a and supported slidably.Button 88 and pressing lever 89 utilizes the power of reversing that is produced by backspring 90, in Figure 20 (a), illustrate left to power and by not shown holding positions such as brake.
Be provided with the switch main body 92 of microswitch for example etc. in a side that contacts with the door body 5a of framework 87, be provided with from switch main body 92 to control circuit 41 distribution 94 in the inside of framework 87.
If the user pushes button 88 with hand, then shown in Figure 20 (b), formation will be pushed button 88 and pressing lever 89 structure to the only mobile pressing quantity 91 in diagram right side, pressing lever 89 is pushed plunger 93 and the closed not shown contact that is arranged on switch main body 92 inside that is arranged on the switch main body 92, thereby the signal that the user can be pushed button 88 passes to control circuit 41.
If the user leaves hand and pushes button 88, then the diagram left that produces by backspring 90 of button 88 and pressing lever 89 to power move to the diagram left, return to the state shown in Figure 20 (a), the contact of plunger 93 recoveries and switch main body 92 inside turns back to the state of disconnection.By such formation, can constitute switch main body 92 and the distribution that switch main body 92 is connected to control circuit 41 is configured in the structure of the inside of main body side framework 87, so have the effect that distribution needn't be set on door body 5a.
Different with said structure, if on door body 5a, switch main body 92 is set, then control circuit 41 be drawn and be connected to distribution 94 must to main body 1 from door body 5, and a door body 5a is the structure that opens and closes as drawer type, so distribution 94 need have than the big length of the maximum opening of refrigerating chamber 5 when closing refrigerating chamber 5 and be in lax state.In this structure, when pulling out refrigerating chamber 5, need above-mentioned lax distribution 94 also to pull out together, but when opening and closing, distribution 94 might twine or hang over the somewhere.
Closing control when common describes.
Use the control sequence when closing refrigerating chamber 5 of so-called half-open state that Figure 11 never closes fully to refrigerating chamber 5 to describe.Figure 11 is the flow chart of the closing control order of expression when closing refrigerating chamber 5.After beginning control (square 51), if first test section 17a fails to detect closing of door, and the opening that second test section 17b detects door and refrigerator main body 1 is after opening is below 35, and then refrigerating chamber 5 is in opening below 35 and the state of opening.If second test section 17b fails to detect door, then refrigerating chamber 5 is in opening more than 35 and the state of opening, so can't close with door open/close machine of the present invention.This occasion after the half-open door state continuance stipulated time (for example about 1 minute), makes and informs that mechanism 70 rings and will be as the alert notification user (square 57) of half-open door.
If second test section 17b detects door, then because refrigerating chamber 5 is in half-open door state and in the zone that can be closed by door drive 10, so to motor 24 energisings (square 58).The direction of rotation of this moment is the CW direction in Fig. 7.And, at this moment, be reduced to for example 1/2 to 1/3 degree of rated voltage by the voltage that will impose on motor 24, thereby the rotating speed of swivel plate 19 is reduced, then owing to swivel plate 19 rotates to the CW direction with low speed, so the 3rd drive pin 20c does not produce the bump that conflicts with the 3rd bearing plane 21c of web 16 and is good.
Make motor 24 make swivel plate 19 reach the state of Fig. 7 (b) to for example 3 seconds stipulated time of CW direction energising (square 59), the direction that makes web 16 promptly close refrigerating chamber 5 to arrow 36 directions moves closes refrigerating chamber 5.After process institute fixes time, this time motor 24 energisings are moved (square 60) to the CCW direction, shown in Fig. 7 (c), swivel plate 19 rotates to former point range 40 (shown in Figure 8), if the signal detection of utilizing rotation testing agency 32 then makes the rotation of motor 24 stop (square 62) to being in initial point scope 40 backs (square 61).Here,, can confirm that then refrigerating chamber 5 is fully closed if first test section 17a detects the situation (square 63) that refrigerating chamber 5 is closed, thus end process (square 66).If first test section 17a fails to detect closing of refrigerating chamber 5, then continuing half-open door state owing to being judged as, so, repeat repeatedly to carry out from square 58 to square 63 the processing action (square 64) that promptly 24 energisings make swivel plate 19 to the rotation of CW direction refrigerating chamber 5 be closed to motor.If the number of times that repeats to stipulate, for example first test section 17a also do not detect closing of door behind three these closing motions, then for example be judged to be and clamped by something and can not close refrigerating chamber 5, make and inform that mechanism 70 pipes user's (square 65) is informed in the alarm that is in half-open door.
Have again, open switch 8 and open the phenomenon that refrigerating chamber 5 is run into child's health etc. in order to prevent that the mistake of child for example from pushing, also can make the structure that can set as follows: thus the user can select to make the exercise void of opening switch not carry out the opening action of explanation refrigerating chamber 5 among Figure 10, and only carry out closing motion shown in Figure 11.
The structure that enlarges stroke with quaternary structure is described.
Above-mentioned explanation the mode that three drive pins 20 are set on swivel plate 19 is illustrated, but drive pin 20 is not limited to three, describes in Figure 12.Figure 12 is illustrated on the swivel plate 19 from driving shaft 18 to (＞r3) position is provided with 4 wheel driven untie-sell 20d apart from r4.On web 16, be provided with the 4th bearing plane 21d that is used for butt 4 wheel driven untie-sell 20d.
When opening the action of refrigerating chamber 5, carry out and same action shown in Figure 6, and because 4 wheel driven untie-sell 20d pushes the 4th bearing plane 21d to the diagram left, so that web 16 is subjected to from the scope of the power of swivel plate 19 is extended.In addition, because r4＞r3, so if the rotating speed of driving shaft 18 is fixed, then 4 wheel driven untie-sell 20d compares with the occasion that does not have 4 wheel driven untie-sell 20d and can strengthen r4/r3 to illustrating the speed that left pushes the 4th bearing plane 21d.As described above, because the scope and the speed both sides of power are extended,,, push the reaction of opening the opening action behind the switch 8 and improve, thereby can obtain comfortable operation sense from the user so the opening of refrigerating chamber 5 increases when opening refrigerating chamber 5.
And, swivel plate 19 is equally being moved web 16 and when closing refrigerating chamber 5 to arrow 36 directions to arrow C W direction rotation and with illustrated in fig. 7, though 4 wheel driven untie-sell 20d pushes the 4th bearing plane 21d, but because 4 wheel driven untie-sell 21d self-powered moving axis 18 is bigger than the 3rd drive pin 21c apart from r4, so, even the only big r4/r3 of the opening 35 of web 16 also can close refrigerating chamber 5.Like this, owing to can enlarge the opening 35 that to close from half-open door state,, realizes to prevent energy-conservation the time food deposited extraneous gas deterioration because of intrusion so, also can close refrigerating chamber 5 more reliably even half-open door takes place.
Installation to switching mechanism describes.
Next uses Figure 14-Figure 17, and rotation driving body in the refrigerator that door drive shown in Figure 3 10 assembling is actual time the and the structure that links parts describe.
In the drawings, driving mechanism, 18 expression driving shafts, 19 expressions that 10 expression door drives, 15 expressions are installed in refrigerating chamber diapire side utilize above-mentioned driving shaft 18 and the swivel plate of rotation, as shown in the figure, on this swivel plate 19, be provided with as the drive pin 20 (20a... first drive pin, 20b... second drive pin, 20c... the 3rd drive pin, the untie-sell of 20d... 4 wheel driven) that enlarges the drive transmission member of stroke with quaternary structure.
And the distance between this drive pin 20a, 20b, 20c, 20d and the drive pin 18 forms, and according to the order of the opposite direction CW of the direction CCW of 19 rotations of the swivel plate when opening drawer door, is positioned at the elongated position of distance at spinning center.
In addition, the short transverse H size of this drive pin 20a, 20d is made as shown in figure 16 than high about 2 times of the height dimension of drive pin 20b, 20c.In other words, as shown in figure 15, drive pin 20b, 20c do the butt position of the above-mentioned short transverse of the origin cause of formation different and on bearing plane 21b, the 21c of the web 16 of drive pin 20a, 20d institute butt the size of butt not.
Like this, can prevent that also drive pin 20b from nipping bearing plane 21a and swivel plate 19 and web 16 are braked unusually if between swivel plate 19 and web 16, take place.Equally, because of the butt position difference of above-mentioned short transverse, can prevent the drive pin 20c bearing plane 21d that nips.
95 are arranged on the magnet on the swivel plate 19, and this magnet 95 utilizes driving shaft 18 and the initial point of the swivel plate 19 that rotates is looked for the position.
Promptly, the rotation version 19 that driven by driving shaft 18 rotates the back as illustratedly just now like that often stops at position shown in Figure 15, even for example also can be with web 16 an interference available in advance switching of manually carrying out such as the occasion of power failure etc.
Therefore, stop in the position of above-mentioned magnet 95 (position shown in Figure 15 (former point range 40 is with reference to Fig. 8)).In other words, be installed on the base plate 15a of swivel plate 19 inboards the stopping or moving of control driving shaft 18 with detecting the Hall IC (not shown) whether magnet 95 be positioned at former point range 40.
In addition, this rotation testing agency 32 certainly is the variable resistance that its resistance value changes by the rotation of axle as explained above, also can be the detection means of microswitch etc. that detects the assigned position of axle.
96 are arranged on the guide on the bedplate 15a that is formed with driving mechanism 15.This guide 96 is made and is arranged side by side two tab 96a, 96b, and the opening of entrance side is compared with other place, forms as shown in Figure 15 broadlyer.This is to enter guide 96 easily for the sliding part 16a (with reference to Figure 17) that makes web 16.That is, because web 16 is installed in drawer door one side, the scale error of refrigerator main body one side is subjected to the influence of assembly error naturally, also is equipped with the scale error of drawer door one side of web 16, the influence of assembly error certainly.Therefore, skew about the position of the sliding part 16a that slides in guide 96 earlier often produces.Because this error is arranged, the sliding part 16a of web 16 enters guide 96 at an easy rate.
In addition, on above-mentioned tab 96b, be provided with two Hall IC 97,98.This Hall IC 97,98 detect magnet 99 on the sliding part 16a that is arranged on web 16 near or deviate from going forward side by side action and do, make driving shaft 18 stalls that drive swivel plate 19.
That is, whether Hall IC 97 detects the door of refrigerating chambers 5 and closes fully, and the magnet 99 of Hall IC 98 and web 16 sides together detects the opening (for example opening is below 35) whether the opening of the door of refrigerating chamber 5 is promptly stipulated in the driving scope of closing of swivel plate 19.
Promptly, as shown in figure 16, magnet 99 and Hall IC 97 and Hall 98 are buttoned-up status (for example opening 35) when relative, and magnet 99 is half-open door state (for example opening 35) between Hall IC 97 and Hall 98 time, is that drawer door is in the state of closing the driving scope.And when half-open door state, controlling organization shown in Figure 9 is controlled, and makes swivel plate 19 to CW direction rotation shown in Figure 12 and drawer door is closed.In addition, usual under buttoned-up status the door of refrigerating chamber 5 be in standby.
Above-mentioned swivel plate 19 and web 16 are by moving respectively with (enlarging stroke with quaternary structure) described above same main points.
And the difference of this structure and above-mentioned (enlarging stroke with quaternary structure) is, makes the first drive pin 20a and only is connected to structure on the first bearing plane 21a.
That is, because the first drive pin 20a is different with second its height dimension of drive pin 20b, the second drive pin 20b makes the structure that reaches the first bearing plane 21a.Another big difference is, makes guide 96, and on the tab 96b that forms this guide 96 two Hall IC 97,98 is set.
Promptly, these two Hall IC 97,98 concern by the position with the magnet 99 that is arranged on web 16 sides, carry out the opening action of refrigerating chamber 5 reliably, and, even refrigerating chamber 5 is in the half-open door state of not closing fully, also can be by making swivel plate 19 to the direction rotation opposite with the occasion of opening refrigerating chamber 5, web 16 is applied the power of the direction of closing refrigerating chamber 5 and it is closed, so, prevent that half-open Men Bingke is prevented cooling performance and reduces or energy-conservation effect.
Certainly, the face that reverses 22 of this web 16 utilizes main points illustrated in fig. 7, utilizes 4 wheel driven untie-sell 20d to the direction pushing of closing door.
In addition, for the action that makes drive pin 20d this moment is carried out well, the face 22 that reverses is preferably made in advance from the following inclined plane of the angle vertical with sliding part 16a 45 degree.
In addition, drive unit 15 usefulness bolts etc. are fixed on the casing side that constitutes refrigerating chamber 5.Therefore, when pulling out the door of refrigerating chamber, swivel plate 19 is stayed the casing side certainly.On the other hand, the web 16 that is installed in refrigerating chamber door one side is pulled out with door.When this door was pulled out, the matching relationship of Shuo Ming swivel plate 19 and web 16 was disengaged certainly just now.In other words, the installation constitution of above-mentioned swivel plate 19 and web 16 accounts for very important component.
For this reason, in the present embodiment, when guaranteeing that integral production is equipped with the size of the base member 15a of swivel plate 19 and guide 96, the gathering sill width dimensions that forms between tab 96a, the 96b of this guide 96 is made the wall thickness of the sliding part 16a that approaches web 16 sides, thereby guarantee both installation sites of swivel plate 19 and web 16 and make the size relationship stabilisation.
Have again, web 16 is installed in door one side and the deviation that causes, deal with by the amount of lap of fully guaranteeing tab 96a, 96b and sliding part 16a in advance to the size up and down of casing.
Action to last hypomere describes.
Have again, the occasion that door drive of the present invention is set refrigerating chamber 5 and vegetable compartment 6 both sides is described.Here as shown in Figure 2, vegetable compartment 6 is positioned near the bottom surface of hypomere, and section is provided with refrigerating chamber 5 thereon.
When refrigerating chamber 5 is opened in the front that the user stand in refrigerator 1, if with the electronic amount of opening refrigerating chamber 5 if in for example 15cm-20cm degree, can see the inside of refrigerator when then opening from peristome.On the other hand, in vegetable compartment 6, because vegetable compartment 6 is positioned near the floor, if similarly open with refrigerating chamber, the student of vegetable compartment 6 end might be run into user's tiptoe when then opening.
In order to prevent when having opened door, student's end of vegetable compartment 6 is run into user's tiptoe, for the consideration of secure context, it is low to wish to be positioned at the opening speed that the vegetable compartment 6 of hypomere compares when opening with the refrigerating chamber 5 that is positioned at epimere, and opening for example is decreased in the 10cm.
In addition, in the above description, vegetable compartment is positioned at the refrigerating chamber hypomere describes, but wish also that in the occasion that refrigerating chamber is positioned at the vegetable compartment hypomere opening of refrigerating chamber and opening speed are littler than vegetable compartment.
Closing control during the butt joint energize describes.
Control sequence when next uses Figure 21 that the power supply and the recovery of connecting refrigerator main body 1 had a power failure (hereinafter referred to as connecting power supply) describes.Figure 21 is the flow chart of the closing control order of expression when connecting the power supply of refrigerator main body 1.If refrigerator main body 1 is connected power supply, then begin the control (square 51) of door drive 10, if fail to detect close (square 54) of door as the Hall IC 97 of first test section, and be ormal weight (for example be positioned at close the driving scope opening below 35) afterwards (square 56) as the opening that the Hall IC 98 of second test section detects door and refrigerator main body 1, then refrigerating chamber 5 is in the state opened of opening below 35.If the Hall IC 98 as second test section fails to detect door, then refrigerating chamber 5 is with opening more than 35 and opening, so can't close with door open/close machine of the present invention.This occasion after if half-open door continues the stipulated time (for example about 1 minute), then makes and informs that mechanism 70 rings and with the alert notification user (square 57) of half-open door.
