The specific embodiment
Below, describe with reference to the refrigerator of accompanying drawing one embodiment of the present invention.
At first, with reference to Fig. 1 and Fig. 2 the overall structure of refrigerator is described.Fig. 1 is the stereogram of the refrigerator of one embodiment of the present invention, and Fig. 2 is the sectional view of the refrigerator of Fig. 1.
Refrigerator main body 1 has a plurality of storerooms 2～6.The topmost of refrigerator main body 1 is a refrigerating chamber 2, as the example of its 2a, and the so-called double door that open the oriented left and right sides.The storeroom that the below of refrigerating chamber 2 is cut apart about being, on one side for example it is that function is switched chamber 3, another side is to store ice cube of making by the not shown device that freezes automatically and the ice-making compartment 4 that takes out.Function switching chamber 3 and ice-making compartment 4 are provided with door 3a, the 4a of the drawer type of ON/OFF front openings.And its underpart is the refrigerating chamber 5 with the drawer door 5a that can extract out, and foot also is the vegetable compartment 6 with drawer door 6a.Door at refrigerating chamber 2 has operation display part 7 on the 2a, has the door unlatching switch 8 that is used to that door drive 10 is opened the door and drives on operation display part 7.This unlatching switch 8 comprises the door unlatching switch 8b that door unlatching switch 8a that refrigerating chamber uses and vegetable compartment are used.Handle 112 when on each, having opening-closing door.
Below, with reference to Fig. 2 the door drive in the refrigerating chamber 5 10 is described.In addition, the structure of the door drive in the vegetable compartment 6 is identical with door drive 10 in the refrigerating chamber 5, therefore omits repeat specification.
The container 12 that the back side of the door 5a of refrigerating chamber 5 has store food, container 12 is supported in the mode that can freely extract out forward by guide rail (sliderail) 11.Be provided with as the closer (closer) 13 that pulls the closing function power unit of refrigerating chamber 5 to the direction of closing the door in the inboard of guide rail 12.When closing the refrigerating chamber of temporarily opening 5, open amount for example for 50mm when following this closer 13 apply power by the inside layback of power of not shown spring, auxiliary action of closing refrigerating chamber 5 is closed the door until magnetic force door envelope (magnet packing) 14 on every side that is arranged on refrigerating chamber 5 and 1 absorption of refrigerating chamber main body.
In refrigerating chamber 5, be provided with door drive 10.This door drive 10 comprises: driving mechanism 15, and it has at the fixing drive source of refrigerator main body 1 side is the reducing gear 25～30 (Fig. 4 and Fig. 5) of the rotation of motor 24 (with reference to Fig. 4 and Fig. 5) and this motor 24 that slows down; And joint cover 16, this joint cover 16 is arranged on the coupling component with the lower inside of the open/close container 12 of refrigerating chamber door 5a.In this door drive 10, on the moving direction of guide rail 11, apply power with ON/OFF refrigerating chamber 5 by 15 pairs of joint covers 16 of driving mechanism.Detailed 26S Proteasome Structure and Function about driving mechanism 15 and joint cover 16 will be described hereinafter.
Be provided with a state detection unit 17 in the front of refrigerating chamber 5, whether detect refrigerating chamber door 5a is opened, the open amount that perhaps detects refrigerating chamber door 5a and sends its signal to control part described later whether in for example scheduled volume about 30mm (open amount 35 of driving amount is closed in conduct described later).
Below, with reference to Fig. 3 to Fig. 5, the structure of door drive 10 with driving mechanism 15 and joint cover 16 is described.Fig. 3 is a plane of overlooking the door drive 10 with driving mechanism 15 and joint cover 16 from the top of Fig. 2, and Fig. 4 is the vertical view of the internal structure of driving mechanism 15, and Fig. 5 is the upward view of the internal structure of driving mechanism 15.
In driving mechanism 15, around being driving shaft 18, supports rotating output shaft swivel plate 19 as the rotation driving body with rotating freely, on swivel plate 19, have as the drive pin (spin) 20 that drives transfer part.In the present embodiment, be provided with 3 drive pins 20,, be provided with the first drive pin 20a, be provided with the second drive pin 20b, be provided with the 3rd drive pin 20c at distance r3 at distance r2 at distance r1 according to distance from driving shaft 18.Each drive pin 20 forms drum.The central shaft of drive pin 20 is parallel with the rotary middle spindle of driving shaft 18.Here, r1＜r2＜r3.In the present embodiment, when opening refrigerating chamber door 5a, swivel plate 19 rotates to arrow C CW direction.
As previously described, because joint cover 16 is arranged on the drawer door of refrigerating chamber 5, therefore on arrow 23 directions, move freely along guide rail 11.In Fig. 3, illustrated left is to the front that is refrigerator, and joint cover 16 direction left moves, and opens refrigerating chamber door 5a thus.Joint cover 16 has when opening refrigerating chamber 5 and the contacted first bearing plane 21a of the first drive pin 20a, with the contacted second bearing plane 21b of the second drive pin 20b, with contacted the 3rd bearing plane 20c of the 3rd drive pin 20c.To describe drive pin 20 and bearing plane 21 actions in the back in detail.
As Fig. 4 and shown in Figure 5, the rotating shaft of motor 24 is provided with motor pinion (motorpinion) 25, is decelerated with idle pulley (idler) 26 engagements.Idle pulley 26 and idle pulley pinion (idler pinion) 27 becomes one and rotates, idle pulley 27 and gear 28 engagements.Idle pulley 28 and idle pulley pinion 29 rotate integratedly, and idle pulley pinion 29 is decelerated with driven wheel (gear) 30 engagements.Driving shaft 18 is connected with driven wheel 30.
By the structure of such transmission device, the rotary speed of motor 24 for example is reduced to about 1/100, makes swivel plate 19 rotations that are arranged on the driving shaft 18.In the present embodiment, between idle pulley 28 and idle pulley pinion 29, be provided with torque limiter 31.When swivel plate 19 had been applied excessive external force, torque limiter 31 actions can prevent the damage of driving mechanism 15 thus so that idle pulley 28 and idle pulley pinion 29 slide mutually.In addition, rotary detecting circuit 32 is set on driving shaft 18, thereby can detects the position of rotation of driving shaft 18.As an example of such rotary detecting circuit 32, can enumerate the variable resistance that its resistance value changes along with the rotation of axle.
Below, the action when opening refrigerating chamber door 5a by door drive 10 describes with reference to Fig. 6.Fig. 6 is the schematic diagram of the action of door drive 10 when opening refrigerating chamber door 5a, and (a) the expression state of closing refrigerating chamber 5 identical with Fig. 3 represented by according to (b) (c) (d) operation in tandem (e) action of opening refrigerating chamber 5.
Swivel plate 19 rotates freely around driving shaft 18, and it is supported that joint cover 16 can move freely ground at not shown left and right directions, and refrigerating chamber 5 has joint cover 16, so the breakdown action of the mobile expression refrigerating chamber 5 of the direction left of joint cover 16.Here, the datum line of opening the diagram left position of the joint cover 16 under the state of refrigerating chamber door 5a is expressed as draws in position 34.
Swivel plate 19 under the state of the first drive pin 20a and contacted Fig. 6 of the first bearing plane 21a (b), produces the power of arrow 23a direction to the rotation of arrow C CW direction at joint cover 16.At this moment, the first drive pin 20a is from the position of driving shaft 18 apart from r1, if therefore the facility torque that is added in driving shaft 18 is T, then the power that passes to joint cover 16 by the first drive pin 20a is T/r1.Making a concerted effort of the power of the food weight that this power is made as the own wt of the tractive force of power greater than the magnetic force door envelope of peeling off refrigerating chamber door 5a, closer 13 and mobile refrigerating chamber door 5a and deposits.Thus, peel off the absorption of magnetic force door envelope, joint cover 16 with refrigerating chamber door 5a to the diagram left to moving, thereby refrigerating chamber door 5a begins to open.
Further, under the state of Fig. 6 (c) of CCW 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 the first bearing plane 21a.Therefore that is, the second drive pin 20b is positioned at from the position of driving shaft 18 apart from r2, and r2＞r1, compares with the first drive pin 20a, and the second drive pin 20b is bigger from the distance as the driving shaft 18 of pivot.Therefore, with after the second bearing plane 21b contacts, the first drive pin 20a leaves the first bearing plane 21a at the second drive pin 20b.Compare with the first drive pin 20a, the circumferential speed of second drive pin 20b rotation is faster.
Under the state of this Fig. 6 (c), the second drive pin 20b contacts with the second bearing plane 21b, applies the power of arrow 23b.At this moment, the distance between the position of the second drive pin 20b and the driving shaft 18 is shown in Figure 3 apart from r2, if therefore the facility torque that is added in driving shaft 18 is T, is T/r2 from the second drive pin 20b by the power that the second bearing plane 21b passes to joint cover 16 then.This power is less than in the power that is applied to joint cover 16 by the first drive pin 20a on the direction of arrow 23a under the state of Fig. 6 (b).But,, therefore the power that applies this moment is set at greater than the tractive force of closer 13 and is moved further the own wt of refrigerating chamber door 5a and the getting final product with joint efforts of the power of the food weight deposited because magnetic force door envelope is stripped from.Like this, joint cover 16 with the door of refrigerating chamber 5 further to the diagram left to moving, proceed the breakdown action of refrigerating chamber door 5a.
Further, under the state of Fig. 6 (d) of CCW 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 the second bearing plane 21b.Therefore that is, the 3rd drive pin 20c is positioned at from the position of driving shaft 18 apart from r3, and r3＞r2, compares with the second drive pin 20b, and the 3rd drive pin 20c is bigger from the distance as the driving shaft 18 of pivot.Therefore, with after the 3rd bearing plane 21c contacts, the second drive pin 20b leaves the second bearing plane 21b at the 3rd drive pin 20c.Compare with the second drive pin 20b, the rotation circumferential speed of the 3rd drive pin 20c is faster.
Under the state of this Fig. 6 (d), the 3rd drive pin 20c contacts with the 3rd bearing plane 21c, applies the power of arrow 23c.At this moment, the distance of the position of the 3rd drive pin 20c and driving shaft 18 is shown in Figure 3 apart from r3, is T if therefore will be applied to the torque settings of driving shaft 18, is T/r3 from the 3rd drive pin 20c by the power that the 3rd bearing plane 21c passes to joint cover 16 then.This power is less than being applied to power on the joint cover 16 by the second drive pin 20b on the direction of arrow 23b.But, because refrigerating chamber door 5a carries out breakdown action and moves to arrow 23c direction, therefore refrigerating chamber door 5a has correspondence and comprises the own wt of container and food and the momentum of speed, resist the pulling force of closer 13 by this momentum and from the power that the 3rd drive pin 20c passes to the 3rd bearing plane 21c of joint cover 16, thereby can continue breakdown action.
Further, under the state of Fig. 6 (e) of CCW direction rotation, represent that the 3rd drive pin 20c leaves the state of the 3rd bearing plane 21c substantially at swivel plate 19.Scope from the state of Fig. 6 (a) to the amount of movement 33 of the joint cover 16 of the state of Fig. 6 (e) is that the scope of joint cover 16 power that is subjected to drive pin 20 is promptly opened the driving scope.Here, preferably the amount of movement 33 of this joint cover 16 is set at greater than based on the amount of drawing in of closer 13 promptly greater than closing function power scope.This be because, suppose that closing function power scope is 40mm based on the draft travel of closer promptly, the amount of movement 33 of joint cover 16 is 50mm, even then joint cover 16 stops, is that refrigerating chamber door 5a stops on the position shown in Fig. 6 (e), can be owing to closer 13 cuts out the refrigerating chamber door 5a that has just opened yet.
But, from Fig. 6 (e) thus state further open refrigerating chamber door 5a joint cover 16 move to the diagram left to the time, joint cover 16 is not subjected to the driving force from drive pin 20, but because refrigerating chamber door 5a has the speed to arrow 23d direction, therefore continue breakdown action, until because the friction load that guide rail 11 has and slow down slowly and stop.Because so action, the open amount of refrigerating chamber door 5a is greater than the amount of movement 33 of joint cover 16.
As mentioned above, can be achieved as follows action: when carrying out the breakdown action of refrigerating chamber door 5a, do not continue to apply driving force to the direction of opening the door, and only apply the driving force of the shorter scope that begins to open, afterwards, frictional force by guide rail, the translational speed that obtains in the scope of driving force is slowed down slowly and is stopped, subscriber station is when the front of refrigerating chamber door 5a thus, when perhaps object being arranged, even refrigerating chamber door 5a is approaching, do not apply driving force to the door drive 10 of opening direction yet, so safety.
As mentioned above, when beginning to open refrigerating chamber door 5a from closed condition, being configured in the first drive pin 20a from the nearest position of driving shaft 18 releases joint cover 16 and drives, but has bigger power though speed is little thus, thereby peel off magnetic force door envelope, the second drive pin 20b that is arranged on the position more farther than the first drive pin 20a continues to release joint cover 16, apply medium speed's moderate force, resist the tractive force of closer 13 thus and continue breakdown action, accelerate the speed of refrigerating chamber door 5a thus, further, the 3rd drive pin 20c that is arranged on the position more farther than the second drive pin 20b continue to release joint cover 16 and with the little but fast speed drive of power, therefore can further accelerate the speed of refrigerating chamber door 5a thus, use the motor 24 of less driving torque can be reliably and promptly carry out the breakdown action of refrigerating chamber door 5a.
In the structure of present embodiment, from driving shaft 18, drive pin 20 contact with joint cover 16 and the position that applies driving force in the slightly vertical direction of the opening direction 23 of relative refrigerating chamber door 5a, so rotary speed of the speed 23 of drive pin 20 and swivel plate 19 and proportional to the length of the arm of drive pin 20.Thus, compare, can easily realize releasing the high speed of the speed 23 of a 5a with the structure of the changing unit of radius till the cam that uses rotation is only released door the contact of cam and door portion.Structure by present embodiment, owing to can be achieved as follows action, therefore this structure is very suitable, this action is: the driving force that only applies the shorter scope that begins to open, the frictional force that has by guide rail afterwards, the action that the opening speed 23 that obtains in the scope of the driving force of door drive 10 slows down slowly and stops.
After opening refrigerating chamber door 5a by this action, swivel plate 19 continues to the rotation of CCW direction, stops the rotation after reaching the state of Fig. 6 (a).In addition, this moment is being owing to opening refrigerating chamber door 5a, so joint cover 16 is not positioned at the position shown in Fig. 6 (a), and is in to illustrated left to the state that moves.
In the door drive 10 of present embodiment, after swivel plate 19 has carried out the breakdown action of refrigerating chamber door 5a, if continue, then can get back to state when having closed refrigerating chamber door 5a, can get back to above-mentioned former point range 40 (with reference to Fig. 8) to the equidirectional rotation.Thus, can make swivel plate 19 high speed involutions to former point range 40.If swivel plate 19 is not to rotate to equidirectional, and behind the breakdown action that has carried out refrigerating chamber door 5a, temporarily stop, afterwards to opposite spin and the former point range 40 of involution, then than as present embodiment to equidirectional rotation and the structure of the former point range 40 of involution, it is longer to return the time that former point range 40 consumed.
Fig. 7 (a) is in following state: do not close refrigerating chamber door 5a, and the diagram left end of joint cover 16, and draw in position 34 and compare the distance that has only moved the open amount 35 that is equivalent to carry out closing motion.Usually the tractive force that produces by closer 13 pulls refrigerating chamber door 5a, thereby closes refrigerating chamber door, but sometimes the part of food be stuck or for a certain reason the action of guide rail 11 temporarily stagnate, thereby can not pull refrigerating chamber door.
Here, when make swivel plate 19 around driving shaft 18 when arrow C W direction rotate, the 3rd drive pin 20c face that returns 22 on the left of the diagram relative that contacts with the bearing plane 21 of joint cover 16.Fig. 7 (b) expression with swivel plate 19 further to the state of arrow C W direction rotation, but joint cover 16 released and move to arrow 36 directions by the 3rd drive pin 20c, so the diagram left end of joint cover 16 moves, and draws in position 34 until reaching.Position shown in this Fig. 7 (b) represents that refrigerating chamber door 5a is in the position of closing fully till magnetic force door envelope 14 absorption refrigerator main bodies 1.
Afterwards, make swivel plate 19 be in the state of Fig. 7 (c) to arrow C CW direction rotation, stop after making swivel plate 19 rotate to the position identical with Fig. 3.
By carrying out this action, even refrigerating chamber door 5a does not close completely, be in so-called half-open position, also by making swivel plate 19 to the direction rotation opposite with the situation of opening refrigerating chamber door 5a, come to apply the power of the direction of closing refrigerating chamber door 5a for joint cover 16, thereby can close the door, therefore can prevent half-open.
As mentioned above, power when opening refrigerating chamber door 5a need be peeled off the above power of making a concerted effort of the tractive force of the power of magnetic force door envelope 14 and closer 13, but do not need to peel off the power of magnetic force door envelope 14 at closing time, and the tractive force of generation closer 13, therefore also enough can close with respect to opening force is less by the power of closing that door drive 10 applies.According to present embodiment, when closing refrigerating chamber door 5a, the 3rd drive pin 20c farthest pushes away the face of returning 22 from driving shaft 18, even the driving torque that therefore is applied on the driving shaft 18 is identical when opening, the power of closing is compared with opening force and is decreased to r1/r3, and therefore this structure is very suitable.This structure is because the power of folder is little, and is therefore also as safe as a house when contingency is clipped in finger between refrigerating chamber door 5a and the refrigerator main body 1.
Safer when closing lentamente in addition, lowering closing velocity.Therefore, preferably compare the action of closing with low speed with the action of opening refrigerating chamber door 5a.
Here, with reference to Fig. 2, explanation can be closed the open amount 35 of refrigerating chamber door 5a and promptly be closed the driving scope.Open amount preferably less than the door 5a thickness of the front that forms refrigerating chamber door 5a promptly less than thickness gate 71.This be because, if open amount 35 greater than thickness gate 71, when then beginning to pull refrigerating chamber door 5a, might banjo splint in refrigerating chamber door 5a and vegetable compartment 6 or switch the door gap 72 that produces between the door of chamber 3.But,, can further improve security if open amount 35 less than thickness gate 71, then can not clamped finger.
Below, use Fig. 8 that the appropriate position of the swivel plate 19 when refrigerating chamber door 5a is in closed condition is described.
In Fig. 8, the diagram left end of the joint cover of representing with solid line 16 is with to draw in position 34 consistent, and refrigerating chamber door 5a is in the position of closing.In refrigerator,, also exist the user to extract the situation of refrigerating chamber door 5a out with hand even have door drive 10 as present embodiment.Perhaps, owing to fault, under the situation that door drive 10 is failure to actuate, wish that the user can be with the free ON/OFF of manual mode.The structure that preferably has phenomenons such as manual activity when door drive 10 hinders user's ON/OFF refrigerating chamber door 5a when not occurring in like this manually ON/OFF or repetitive operation.
From refrigerating chamber door 5a closing state, the user extracts refrigerating chamber door 5a out and when opening, the joint cover 16 that is arranged on refrigerating chamber door 5a moves to the position consistency of diagram left side and dotted line.Give " ' in dashdotted position to each symbol " represent.
Here, swivel plate 19 is positioned at the position of representing with solid line of Fig. 8, in this position, the tip that is arranged on the second bearing plane 21b on the joint cover 16 is promptly between the second most advanced and sophisticated 37b and the first drive pin 20a gapped 38, if have in the joint cover 16 second most advanced and sophisticated 37b and the discontiguous position of first drive pin 20a relation when the diagram left moves, joint cover 16 did not contact with drive pin 20a when then the user manually extracted refrigerating chamber door 5a out, opened thereby therefore can freely extract refrigerating chamber door 5a out.
In addition, be positioned at the position 19 ' of dotted line at swivel plate 19, in this position, be arranged between the first most advanced and sophisticated 37a on the joint cover 16 and the 3rd drive pin 20c gapped 39, if have in the joint cover 16 first most advanced and sophisticated 37a and the discontiguous position of the 3rd drive pin 20c ' relation when the diagram left moves, joint cover 16 did not contact with drive pin 20 when then the user manually extracted refrigerating chamber door 5a out, opened thereby therefore can freely extract refrigerating chamber door 5a out.
For joint cover 16 is contacted with drive pin 20, the line that connects the driving shaft 18 and the first drive pin 20a is as long as in the angular range of former point range 40 when the manual ON/OFF refrigerating chamber door of user 5a.Therefore, under the situation of having closed refrigerating chamber door 5a, preferably be set at swivel plate 19 in described former point range 40, also very convenient when manual ON/OFF.The angular range of this swivel plate 19 is called in former point range 40.
Below, use Fig. 9 that the structure that the control that is used for control gate drive unit 10 is is described.Fig. 9 is the block diagram of structure of control system of door drive 10 of the refrigerator of presentation graphs 1.In addition, because the door drive 10 of the door drive 10 of refrigerating chamber door 5a and vegetable compartment door 6a has identical control system, identical handling process, therefore in the following description refrigerating chamber door 5a is described.
Actuating doors is opened switch 8 in that the user is electronic when opening refrigerating chamber door 5a, and will be sent to control part 41 by the signal of this operation generation.The door state detection unit 17 that is arranged on the open/close state of each motor 24 of the driving mechanism 15 of refrigerating chamber 5, the rotary detecting circuit 32 of position of rotation of driving shaft 18 that detects driving mechanism 15 and detecting gate is connected with control part 41.Variable resistance that rotary detecting circuit 32 is changed along with the rotation of axle by resistance value or the detecting units such as microswitch that detect the specific position of rotation of axle constitute.
Door state detection unit 17 comprises: first state detection unit 17a, and it is used for detecting whether fully opened refrigerating chamber door 5a (that is, whether refrigerating chamber door 5a is in closed condition); And second state detection unit 17b, whether its open amount that is used to detect refrigerating chamber door 5a is the open amount of being scheduled to (that is, whether refrigerating chamber door 5a opens fully) below 35.Door state detection unit 17 for example can be at magnetic element that has on the refrigerating chamber door 5a and the Hall element (hallelement) that has on refrigerator main body 1, perhaps also can be detecting units such as microswitch.
Have the unit of reporting 70, it is used for being in half-open position to user notification refrigerating chamber door 5a.This reports unit 70 by making the buzzer buzzing or lighting or extinguish indicator lamp and notify.
Stand-by time in the half-open position of the 42 control refrigerating chamber door 5a of timer portion, each function relevant, actuation time etc. with the ON/OFF of refrigerating chamber 5a.Timer T1 alternation switch 92a is used for the setting value of the continuation time timer T1 of user's changeable refrigerating chamber door 5a when full-gear is changed to half-open position.Timer T2 alternation switch 92b is used for the setting value of the continuation time timer T2 of user's changeable refrigerating chamber door 5a when closed condition is changed to half-open position.
Below, use Figure 10, the unlatching control sequence when opening refrigerating chamber door 5a describes.Figure 10 is the flow chart of the unlatching control sequence of expression when opening refrigerating chamber door 5a.
Behind the beginning breakdown action (S001), control part 41 monitors the state of rotary detecting circuit 32, and whether the swivel plate 19 that detects driving mechanism 15 is in the former point range 40 that begins to move (S002).Here, as shown in Figure 8, so-called former point range 40 is meant that joint cover 16 when being in manual ON/OFF refrigerating chamber 5 do not interfere the state of the scope of drive pin 20 yet.
In the detection of S002, swivel plate 16 to motor 24 energisings, makes swivel plate 19 rotations so that reach former point range (S003) not in former point range 40 time.Control part 41 is according to judging from the signal of rotary detecting circuit 32 which direction swivel plate 16 departs to respect to former point range 40, determines that thus the direction that applies of driving voltage that motor 24 is applied is to rotate to CW direction turning motor 24 or to the CCW direction.
If can detect swivel plate 19 in former point range 40, and control part 41 to motor 24 energisings, makes swivel plate 19 rotations (S005) when detecting the user and having operated door unlatching switch 8 (S004).The direction of rotation of the swivel plate 19 of this moment is arrow C CW direction in Fig. 3, if swivel plate 19 rotations, then drive pin 20 pushes away joint cover 16 as shown in Figure 6, thereby opens refrigerating chamber door 5a., make motor stop (S007), and finish a series of breakdown action (S008) when thereby motor 24 continues position of rotation that rotation can confirm the swivel plate 19 that detects by rotary detecting circuit 32 in former point range 40 time (S006).
Below, use the control sequence of Figure 11 explanation when the state that does not fully close refrigerating chamber door 5a (that is, refrigerating chamber door 5a is in half-open position) ShiShimonoseki refrigerating chamber door 5a.The flow chart of the order of the closing control when Figure 11 is expression pass refrigerating chamber door 5a.
After starting (S051), detect former point range (S052), identical to S003 to the action of motor 24 energisings (S053) with the S001 of above-mentioned Figure 10.
Detect former point range at S052, then detect close (S055) of refrigerating chamber door 5a with first state detection unit 17a of door state cell 17.When in this detection, detecting the closing of refrigerating chamber door 5a, can confirm that refrigerating chamber door 5a is in half-open position but is closed, and therefore finishes to close the door action (S055).When first state detection unit 17a can't detect closing of refrigerating chamber door 5a, whether second state detection unit 17b detects refrigerating chamber door 5a was open amount (S056) below 35 with respect to the open amount of refrigerator main body 1.When second state detection unit 17b can detect refrigerating chamber door 5a in this S056, the open amount of refrigerating chamber door 5a was an open amount more than 35, therefore can't close the door with door drive 10.This moment end process (S066).
The open amount that detects refrigerating chamber door 5a in S056 is that open amount 35 is when following, refrigerating chamber door 5a is in and has opened the state of open amount below 35 (promptly, refrigerating chamber door 5a is in half-open position), and in the zone that can close with door drive 10, therefore to motor 24 energisings (S058).The direction of rotation of this moment is the CW direction in Fig. 7.For motor 24, to the CW direction energising scheduled time (for example, 3 seconds) (S058, S059), swivel plate 19 reaches the state of Fig. 7 (b) thus, and joint cover 16 is moved to the direction (that is, closing the direction of refrigerating chamber door 5a) of arrow 36, thereby close refrigerating chamber door 5a.
Through after the scheduled time, current energising makes motor 24 to CCW direction rotation (S060), make swivel plate 19 rotations, reach former point range 40 (as shown in Figure 8) until swivel plate 19 shown in Fig. 7 (c), when the signal according to rotary detecting circuit 32 can detect in former point range 40 (S061), make motor 24 stop the rotation (S062).Then, first state detection unit 17a detects refrigerating chamber door 5a and whether is closed (S063).Here, when refrigerating chamber door 5a is fully closed, end process (S066).
If first state detection unit 17a can't detect closing of refrigerating chamber 5 in S063, then can be judged as and continue to keep half-open position, therefore repeat processing, promptly repeat following action from (S058) to (S063): thus 24 energisings make swivel plate 19 close refrigerating chamber 5 (S064) to the rotation of CW direction to motor.This closing motion is repeated pre-determined number, for example repeat 3 times after first state detection unit 17a still can't detect when closing, for example be judged as something and clamped and can't close refrigerating chamber 5, and end process.
Then, use Figure 12 and Figure 13 that manual control is at closing time described.Figure 12 be door drive 10 from the door standard-sized sheet time control flow chart, Figure 13 be door drive 10 from the door standard-sized sheet time the sequential chart of action.
Start back (S100) and carry out initial point detection action (S101).It is identical with the S001 to S003 of above-mentioned Figure 10 that this initial point detects action.
Then, whether control part 41 detection refrigerating chamber door 5a become half-open (S102, S104) from standard-sized sheet.Judge whether to become half-open by following order from standard-sized sheet.At first, first state detection unit 17a detects the opening (that is non-closed condition) of refrigerating chamber door 5a and the full-gear (S102) of second state detection unit 17b detection refrigerating chamber door 5a.Here, when detecting two states, can confirm the full-gear of refrigerating chamber door 5a, therefore the half-open position (closed condition of second state detection unit 17b) of the opening (that is non-closed condition) of first state detection unit 17a detection this moment refrigerating chamber door 5a and second state detection unit 17b detection refrigerating chamber door 5a (S102).Here, can confirm that when detecting two states refrigerating chamber door 5a becomes half-open position from full-gear.
After becoming half-open position from full-gear, start half-open position watchdog timer T1 (S105).When continuing to keep half-open position under the situation that half-open position watchdog timer T1 finishes (S106, S107), promptly make and report unit 70 buzzings (S108) with 1 second (S109) for example standby scheduled time in the moment that the motor energising closing motion condition that begins is set up.In this stand-by time, banjo splint also can removed finger after confirming to report unit 70 buzzings under the situation between door gap 72 or refrigerating chamber door 5a and the refrigerator main body 1, so safety.
After the S109 standby scheduled time, carry out the processing shown in (S058) to (S062) with above-mentioned Figure 11 identical, based on the closing motion (S110) of motor 24.Therefore, the user can not prevent that refrigerating chamber door 5a from keeping half-open position at T1 in the time yet under the situation of half-open scope moving door.Figure 13 (a) is that half-open position continues to keep the sequential chart of T1 during the time.
When half-open position is disengaged before half-open position watchdog timer T1 finishes, do not carry out the closing motion of motor 24 and end process (S111).Thus, at the handle portion 112 of wanting to catch refrigerating chamber door 5a and during manual-lock, also can operate safely in phase.Figure 13 (b) is the sequential chart after T1 removed from half-open position in the time.
Here, so-called full-gear is meant that first state detection unit 17a is out, second state that state detection unit 17b is out; So-called half-open position is meant that first state detection unit 17a is out, the state of second state detection unit 17b for closing; So-called closed condition is meant that first state detection unit 17a is pass, the state of second state detection unit 17b for closing.
Then, use Figure 14 and Figure 15 control when opening Door by Hand to describe.Figure 14 is the control flow chart when door is closed of door drive 10, and Figure 15 is the sequential chart of the action when door is closed of door drive 10.
Start back (S200) and carry out initial point detection action (S201).It is identical to (S003) with above-mentioned Figure 10 (S001) that this initial point detects action.When control part 41 detects refrigerating chamber door 5a and becomes half-open (S204) from closing, start half-open position watchdog timer T1 (S205).Continuing to keep half-open position under the situation that timer T2 finishes (S207), promptly making and report unit 70 buzzings (S208) in the moment that the motor energising closing motion condition that begins is set up, thus 1 second (S209) for example standby scheduled time.Therefore, the user also can know the timing of closing automatically in advance under the state of opening refrigerating chamber door 5a lentamente, so safety.
After the S209 standby scheduled time, carry out S058 to S062 with above-mentioned Figure 11 identical, based on the closing motion (S210) of motor 24.Therefore, the user can not prevent that refrigerating chamber door 5a from continuing to keep half-open position at T2 in the time yet when half-open scope moves refrigerating chamber door 5a.Figure 15 (a) is that half-open position continues to keep the sequential chart of T2 during the time.
When half-open position is disengaged before half-open position watchdog timer T2 finishes, do not carry out the closing motion of motor 24 and end process (S211).Thus, in the process of the action of opening refrigerating chamber door 5a, can not close automatically.Figure 15 (b) is the sequential chart after T2 removed from half-open position in the time.
Below, the setting of half-open state continuing time is described.
Have continuation time timer T1 and refrigerating chamber door 5a the continuation time counter T2 when closed condition be changed to half-open position of refrigerating chamber door 5a when opening is changed to half-open position respectively, further counter T2 is set at longer than counter T1, with closing motion the time, compare actuation time when more needing power thus during elongated breakdown action, also can be in phase manual ON/OFF.
In addition, the user by timer T1 alternation switch 92a and timer T2 alternation switch 92b, can be set at the time arbitrarily with timer T1 and timer T2 respectively.Omit detailed establishing method, for example setting timer T1 usually promptly opens Men Shiwei 0.5 second, timer T2 promptly is 1.0 seconds at closing time, thereby mainly be people or the less people who needs the long ON/OFF time of the strength of finger use the time at advanced age, change timer T1 promptly opens Men Shiwei, and 0.8 second, timer T2 promptly are 2.0 seconds at closing time, can come setting-up time according to the user thus, can operate safely.
In addition, in the present embodiment, the situation that is arranged on the drawer door of refrigerating chamber 5 or vegetable compartment 6 with door drive 10 is that example is illustrated, but is not limited to present embodiment, self-evident, under situation about being provided with on the rotary door of refrigerating-chamber door 2, also can obtain same effect.
According to present embodiment, have can the drive installation of electricity consumption flowing mode the door drive of door on refrigerator main body, first state detection unit that comprises the closed condition of detecting gate, and second state detection unit that detects the half-open position of the door that in the scope that can close the door with the opening-closing door unit, is provided with, all detect when being in opening detecting first state detection unit and described second state detection unit, close the door by door drive through after the scheduled time, therefore under the state of foreign matters such as user's clip finger, want manually at closing time, if subconscious to clipping finger, then before beginning to close the door, driver element can remove finger in half-open position.In addition, the half-open position of door continue to keep the scheduled time during can manually close the door, therefore in the process of closing the door, also can not pull by drived unit, can close naturally.Just in case when door is not fully closed, also can fully close the door by door drive.
In addition, have can the drive installation of electricity consumption flowing mode the door drive of door on refrigerator main body, first state detection unit that comprises the closed condition of detecting gate, and second state detection unit that detects the half-open position of the door that in the scope that can close the door with the opening-closing door unit, is provided with, after the closed condition that detects door, close the door by door drive through after the scheduled time, therefore want to open Door by Hand and when door moved to half-open position the user, also can the half-open position of door continuous keep the scheduled time during in the action that continues to open Door by Hand, so driver element can not closed the door in the process of opening the door.Just in case when under half-open position, leaving, also close the door through after the scheduled time, so Men Buhui is in half-open position by door drive.
In addition, with respect to first scheduled time of door when opening is changed to half-open position, it is longer to set second scheduled time of door when closed condition is changed to half-open position, therefore with closing motion the time, compare actuation time when more needing power during elongated breakdown action, also can be in phase manual ON/OFF.
In addition, be provided with and set the scheduled time of door when opening is changed to half-open position and the setup unit of the scheduled time of door when closed condition is changed to half-open position arbitrarily, therefore can come setting-up time according to user's ability, thus advanced age people or the strength of finger is less needs the people of longer ON/OFF time also can operate safely.
In addition, after reporting the unit and report by buzzer etc., close driving, so the user can know the action zero hour of closing the door, can operate safely through opposite house behind the certain hour.
