When multiple combinations of states of air door 140A and 140B are shown in the table that Fig. 7 is listed, air door drive rod 160A, 160B And the state of air door driving wheel 150A, 150B.In the figure 7, framework 110 is removed, to be specifically illustrated in air door driving wheel, wind The relative status of door drive rod and air door.

The view that X sees from front to back along the longitudinal direction is shown in Fig. 7, the grooved tracks of air door driving wheel 150A are shown Multiple states that 151A and air door drive rod 160A coordinates, and the grooved tracks 151B and wind for showing air door driving wheel 150B Multiple states that door drive rod 160B coordinates.In the view of Fig. 7, although post 161A on air door drive rod 160A, 160B, 161B be located at it is invisible between air door drive rod and air door driving wheel, but in order to be clearly shown that matching relationship, with overstriking Circle schematically show the position of post 161A, 161B in grooved tracks.It should be appreciated that the post 161A for showing, 161B is only schematical effect, and in no way limits size and/or the position of post.

Multiple combinations of states of air door 140A and 140B are described below with reference to Fig. 7.

In a first state, air door driving wheel 150A, 150B are in original state, i.e. air door driving wheel 150A, 150B Relative to 0 ° of initial position rotational angle.Initial position described in text refers to post 161A, 161B in grooved tracks 151A, 151B In in initial end when position.Now, post 161A is at the position that radius is R1 in grooved tracks 151A, post 161B In grooved tracks 151B at the position that radius is R3, air door 140A, 140B are in closed position, from without air-flow Flowed out via air stream outlet 101A, 101B.

In the second state, to turn over α 1, i.e. air door driving wheel 150A relative to first state relative for air door driving wheel 150A In initial position rotational angle α 1；It is relative that air door driving wheel 150B turns over β 1, i.e. air door driving wheel 150B relative to first state In initial position rotational angle β 1.Now, post 161A is for the position of R1 is transformed into radius from radius in grooved tracks 151A At the position of R2, and 161B in the grooved tracks 151B still in radius for the position of R3 at,；So as to air door 140A from close stance Put and be converted to open position, air door 140B flows out still in closed position, now air-flow via air stream outlet 101A.

In the third state, it is relative that air door driving wheel 150A turns over α 2, i.e. air door driving wheel 150A relative to the second state In initial position rotational angle α 1+ α 2；Air door driving wheel 150B turns over β 2, i.e. air door driving wheel 150B phases relative to the second state For initial position rotational angle β 1+ β 2.Now, post 161A in the grooved tracks 151A still in radius for the position of R2 at, And 161B in the grooved tracks 151B from radius for the position of R3 is transformed at the position that radius is R4；So as to air door 140A still locates In open position, and air door 140B is converted to open position from closed position, and now air-flow flows via air stream outlet 101A, 101B Go out.

In the 4th state, it is relative that air door driving wheel 150A turns over α 3, i.e. air door driving wheel 150A relative to the third state In initial position rotational angle α 1+ α 2+ α 3；Air door driving wheel 150B turns over β 3, i.e. air door driving wheel relative to the third state 150B is relative to initial position rotational angle β 1+ β 2+ β 3.Now, post 161A is the position of R2 from radius in grooved tracks 151A Put and be transformed at the position that radius is R1, and post 161B in the grooved tracks 151B still in radius for the position of R4 at；So as to Air door 140A is converted to closed position from open position, and air door 140B is still in closed position, and now air-flow goes out via air-flow Mouth 101B outflows.

Table 1 summarize four kinds of working conditions of the air-supply arrangement 100 of the embodiment according to Fig. 7 relevant parameter and The state of each air door.

Four kinds of working conditions of the air-supply arrangement 100 of table 1

The multiple optional state of air door group 140A, 140B that Fig. 7 shows.According to the summary of table 1, and with reference to showing in Fig. 7 The multiple state embodiments for going out, air door drive wheel group 150A, 150B often turns over certain angle, and air door group 140A, 140B is from one State change is to another state.In a preferred embodiment, when air door group switches between each two state, air door driving wheel It is identical angle that each in 150A, 150B turns over identical angle, i.e. α 1, α 2, α 3 respectively, and β 1, β 2, β 3 are identical Angle；In a preferred embodiment, power source output section 132A, 132B, air door driving wheel 150A, 150B are relative to motor 130 rotation axis is arranged symmetrically so that when air door group switches between two states every time, air door driving wheel 150A, 150B Both turn over that equal angular, i.e. α 1 are identical with β 1, and α 2 is identical with β 2, and α 3 is identical with β 3.In alternate embodiments, air door group The angle that is turned over can not be fixed when switching between different conditions, i.e. α 1, α 2, α 3 are differed, or β 1, β 2, β 3 not phase Together；Alternatively, air door driving wheel 150A, 150B turn over different angles, i.e. α 1 with β 1 not when air door group switches between different conditions It is identical, or α 2 and β 2 differs, or α 3 and β 3 is differed.

In the illustrated embodiment, air door group in each switching state, protect by only one air door action, another air door Hold original state.For example, when air door group is switched to the second state from first state, only air door 140A actions；Air door group from When second state is switched to the third state, only air door 140B actions；When air door group is switched to four states from the third state, only Air door 140A is acted.So, when every next state of air door group switches, the radius of the grooved tracks where only one post occurs The radius of the grooved tracks at where change, another post does not change.So as to according to the grooved tracks at two posts places The change successively of radius, realizes four kinds of working conditions of the air door group of air-supply arrangement 100.Because every next state of air door group switches When the action of only one air door (state changes) so that the torque loss of motor output is smaller.Can so use Smaller power is used to drive the state of air door group to switch so as to the motor of smaller size smaller so that the overall body of air-supply arrangement 100 Product is more compact；Simultaneously because the moment of torsion for driving throttle condition to change is smaller, from the torque output of motor 130 to air door The moment of torsion that the drive mechanism of 140A, 140B rotation is born is relatively low, so that drive mechanism is hardly damaged, and service life extends.

In alternate embodiments, it would however also be possible to employ realize that two air doors 140A, 140B are simultaneously dynamic when switching per next state The scheme of work.Such scheme can for greater flexibility configure the order between the various throttle conditions of air-supply arrangement；But, will cause The power consumed when two door openings and closing increases, so that the power of output needed for motor increases, it is possible to increase The cost and volume of motor.

In the solution of the present invention, in air-supply arrangement 100, two air door driving wheel 150A, 150B are electric relative to driving Machine 130 is arranged symmetrically, and is driven by the only one motor 130.Two shapes of air door are controlled using single motor simultaneously State is combined, and can reduce cost, and realize relatively simple refrigerator control program.

Air door drive rod 160A, 160B are driven in air door driving wheel 150A, 150B, and then drives air door 140A, 140B In rotary course, grooved tracks 151A, 151B of air door driving wheel 150A, 150B will apply along vertical on post 161A, 161B The component of the power of direction Z, so that air door drive rod 160A, 160B have the trend for deviateing transverse direction Y movement.Air door drives The cooperation of gathering sill limiting section 121A, 121B on gathering sill 163A, the 163B and framework 110 on bar 160A, 160B, and/or The association of another gathering sill limiting section on another gathering sill 163A ', 163B ' and protecgulum 200 on air door drive rod 160A, 160B The trend that resistance air door drive rod deviates transverse direction Y movement is further helped in, to keep the correct behaviour of air door drive rod Make.

Fig. 7 is referred again to, in the first state, air door 140A, 140B are in closed position, and post 161A, 161B The position of initial end is in grooved tracks 151A, 151B.The starting ends optionally are designed to so that post 161A, 161B can be self-locking in original place (such as hook radially inward), prevent air door automatic towards open position rotation.Specifically, this is first The auto-lock function of post is realized in translation of the top portion by limiting the Y in transverse direction of air door drive rod.

With continued reference to Fig. 7, when the closing of air door driving wheel 150A control air doors 140A and opening, grooved tracks 151A is half Change between footpath R1 and R2.Air door driving wheel 150A receives torque from motor 130, and by torque via air door drive rod 160A is exported to air door 140A.The constant torque of air door driving wheel 150A outputs, and R1>R2, therefore when on air door drive rod When post 161A moves closer to radius R2, the arm of force at center of the post away from air door driving wheel 150A is shorter, so that the power for producing is bigger； When the post 161A on air door drive rod moves closer to radius R1, the arm of force at center of the post away from air door driving wheel 150A is more long, So as to the power for producing is smaller.

Similarly, when air door driving wheel 150B controls the closing of air door 140B and opens, grooved tracks 151B is in radius R3 Change and R4 between.Air door driving wheel 150B receives torque from motor 130, and torque is exported to wind via air door drive rod Door 140B.The constant torque of air door driving wheel 150B outputs, and R3>R4, therefore when the post 161B movements on air door drive rod connect During nearly radius R4, the arm of force at center of the post away from air door driving wheel 150B is shorter, so that the power for producing is bigger；When air door drive rod On post 161B when moving closer to radius R3, the arm of force at center of the post away from air door driving wheel 150B is more long, so that the power for producing It is smaller.

Therefore, when air door 140A, 140B nearly closed position, the power for being delivered to post 161A, 161B is smaller；Work as air door When 140A, 140B are close to open position, the power for being delivered to post 161A, 161B is bigger.

Fig. 8 schematically shows the side view of the opening and closing position of air door 140A, 140B, shows drive mechanism The view that X (along direction A in Fig. 2) sees from back to front in a longitudinal direction.Air door 140A revolves between the open and closed positions Gyration θ_A, air door 140B anglec of rotation θ between the open and closed positions_B.In a preferred embodiment, θ_AWith θ_BIt is equal.Such as Shown in Fig. 8, θ_A/θ_BIt is less than 90 ° of acute angle.Preferably, θ_A/θ_BIn the range of 70 ° to 90 °.It is highly preferred that θ_A/θ_BSet It is 80 ° of angle.If by the anglec of rotation θ of air door_A/θ_BSelectively too small (being, for example, less than 70 °), then can cause that air door length increases Plus, air door deadweight is consequently increased, while will cause Wind power propelling wind when cold wind air-flow is conveyed, because of the length increase of air door Men Shiyin brachiums driver part torque required when increasing and causing door opening and close increases；Additionally, with door-plate length Increase, air-supply arrangement is lengthened along the overall distance in air current flow direction, causes volume to increase, and may be deposited in actual production process In the problem of waste of material, and due to the long length of door-plate, the power for being delivered to air door end may be smaller, and is difficult to protect Excellent sealing of the card air door in end.If by the anglec of rotation θ of air door_A/θ_BSelect to be excessive (being greater than 90 °), may lead The transmission device in drive mechanism is caused (for example, air door drive rod 160A and air door actuator 170A, and air door drive rod 160B And air door actuator 170B) between cooperation stroke increase, (for example, air door driving wheel 150A, 150B and/or air door drive rod The size of 160A, 160B needs to design larger), further cause the increase of the overall volume of air-supply arrangement 100, particularly edge The increase of the length of transverse direction Y.When the air door anglec of rotation is excessive, air door drive rod (and tooth bar thereon) it is mobile away from From elongated, while the radius changing rate of the grooved tracks in air door wheel drive surfaces can change and because tooth bar displacement increases In precipitous, increased so as to the torque for causing door-plate motor in switching state is lost.Therefore, air door anglec of rotation θ_A/θ_BIt is reasonable Selection can be while realizing that motor torque loss is minimum, the volume of reduction air-supply arrangement 100.

With continued reference to Fig. 8, air door 140A includes the panel 143A and seal 144A being arranged on the surface of panel 143A. The sunk structure with reinforcement is optionally provided with the opposite surface with seal 144A of panel 143A such that it is able to Manufacture air door 140A material requesteds are reduced on the basis of the intensity for ensureing air door 140A, mitigates the weight of air door 140A, and So as to reduce power/torque needed for rotary air valve.Framework 110 includes that limiting air-flow goes out at the side for forming air stream outlet 101A The raised brim 122A of the shape of mouth 101A.From figure 2 it can be seen that raised brim 122A is substantially rectangular shape, so that Limit the air stream outlet 101A of rectangular shape.Under the closed position of air door 140A, seal 144A engagements are substantially rectangular The raised brim 122A of shape, and partly by raised brim 122A compressions, so as to be fully closed gas channel 101A.

Similarly, the cooperation of air door 140B and air door 140B and raised brim 122B can also similar mode realize, Will not be repeated here.However, in alternate embodiments, air door 140B can be of different sizes or shape with air door 140A Shape.

In the illustrated embodiment, when air door 140A, 140B are changed from closed position to open position, two air doors are equal To the internal rotating of framework 110, and do not extend to outside framework 110, at this moment air-flow blows to panel 143A, 143B and tends to resisting wind The opening of door；And when air door is changed from open position to closed position, air-flow tends to further pressing to air door accordingly Raised brim, this helps to realize the sealing between air door and corresponding raised brim at closed position.As described above, wind The cooperation of grooved tracks 151A, 151B of door driving wheel 150A, 150B and post 161A, 161B of air door drive rod 160A, 160B It is embodied as：When air door 140A, 140B nearly closed position, the power for being delivered to post 161A, 161B is smaller；When air door 140A, When 140B is close to open position, the power for being delivered to post 161A, 161B is bigger.Therefore, when air door tends to being changed to open position, Being delivered to the larger power of post 161A, 161B helps to overcome the resistance of air-flow；And work as air door and tend to being changed to closed position When, air-flow tends to pushing air door to closed position, so as to further help in the closing and sealing of air door, and transmit simultaneously Post 161A, 161B it is less try hard to avoid exempt from air door respective bump edge clashed into larger impulsive force, reduce make an uproar to a certain extent Sound.

In alternate embodiments, air door is arranged to, and when air door is closed, air-flow has air door To the trend that open position pushes.In such embodiments, the angle of engagement of sector gear 171A, 171B could be arranged to be more than The angle, θ that air door 140A, 140B are rotated through when closing_A/θ_B, so that sector gear can reach closed position laggard in air door Step ground drives air door to be compressed to direction is closed, to realize more closely sealing.

In the air-supply arrangement 100 of exemplary embodiment of the invention, for driving air door 140A, 140B opening The drive mechanism changed between position and closed position is wholly received in the recess of drive mechanism acceptance division 112, and this is recessed Closed by protecgulum 200 in portion so that drive mechanism is accommodated in the space of base closed, and with the air-flow for airflow Throughput 111 is isolated entirely from, so as to avoid air-flow from directly blowing to drive mechanism.

Such arrangement of air-supply arrangement 100 realizes being kept completely separate for airflow part and drive mechanism, from And avoid drive mechanism from being exposed in cold air air-flow.As described above, drive mechanism multiple power transmissions and Its joint, can be provided with lubricant, such as lubricating oil or lubricating grease, to contribute to the transmission of power and reduce friction, carry High efficiency；Poewr transmission mechanism is avoided to be exposed in cold air-flow so that lubricant will not too quickly be waved due to air-flow blow-through Hair, so as to avoid due to lacking Poewr transmission mechanism caused by lubricant to seize up or the generation of noise, and can protect Hold the efficient transmission of the good lubricating condition of drive mechanism and power.Therefore, such arrangement can improve air-supply arrangement 100 operating efficiency, and extend its service life.

In the illustrated embodiment, the element in the drive mechanism of air-supply arrangement 100 is mostly the symmetrical structure being arranged symmetrically Part.In actual production process, the production of symmetrical component, making, process are relatively simple, when greatly can shorten manufacture Between and cost.Additionally, the installation process of symmetrical member is also more simple, it is not error-prone.

Fig. 9-11 shows multiple views of the drive mechanism of air-supply arrangement according to another embodiment of the present invention.

Figure 10 A show the top view and front view of air door driving wheel 1150A.Air door driving wheel 1150A has for connecing Receive and drive the grooved tracks 1151A of the post 1161A of air door drive rod 1160A.In the illustrated embodiment, grooved tracks The pivot of 1151A and the rotation axis coincident of air door driving wheel 1150A.Specifically, grooved tracks 1151A has two not Same orbit radius R11 and R12.When the post 1161A of air door drive rod 1160A is in orbit radius in grooved tracks 1151A During at the position of R11, air door 1140A is in the closed position；When the post 1161A of air door drive rod 1160A is in grooved tracks When in 1151A at the position that orbit radius is R12, air door 1140A is in an open position.

Similarly, Figure 10 B show the top view and front view of air door driving wheel 1150B.Air door driving wheel 1150B has For receiving and drive air door drive rod 1160B post 1161B grooved tracks 1151B.Specifically, grooved tracks 1151A and 1151B has different shapes, so as to when air door driving wheel 1150A, 1150B are driven in rotation, air door 1140A and air door 1140B is driven in a different manner, realizes that various states are combined.The pivot of grooved tracks 1151B and air door driving wheel The rotation axis coincident of 1150B.Specifically, grooved tracks 1151B has in two different orbit radius R13 and R14.Work as wind The post 1161B of door drive rod 1160B in grooved tracks 1151B in orbit radius at the position of R13 when, air door 1140B It is in the closed position；When the post 1161B of air door drive rod 1160B is the position of R14 in orbit radius in grooved tracks 1151B When putting place, air door 1140B is in an open position.

In a preferred embodiment, radius R11 is equal with R13, and radius R12 is equal with R14, and drives air door 1140A With the drive mechanism of 1140B entirety relative to motor 1130 and power source input gear 1131 relative to the symmetrical cloth of longitudinal direction X Put, so that air door 1140A and 1140B turn over identical angle when changing between the open and closed positions.

When multiple combinations of states of air door 1140A and 1140B are shown in the table that Figure 11 is listed, air door drive rod 1160A, The state of 1160B and air door driving wheel 1150A, 1150B.In figure, frame is removed, to be specifically illustrated in air door driving The relative status of wheel, air door drive rod and air door.

The view that X sees from front to back along the longitudinal direction is shown in Figure 11, the groove tracks of air door driving wheel 1150A are shown Multiple states that road 1151A and air door drive rod 1160A coordinates, and the grooved tracks for showing air door driving wheel 1150B Multiple states that 1151B and air door drive rod 1160B coordinates.In the view of Figure 11, although air door drive rod 1160A, 1160B On post 1161A, 1161B be located at it is invisible between air door drive rod and air door driving wheel, but match somebody with somebody to be clearly shown that Conjunction relation, the position of post 1161A, 1161B in grooved tracks is schematically shown with the circle of overstriking.It should be appreciated that Post 1161A, the 1161B for showing are only schematical effect, and in no way limit size and/or the position of post.

Figure 11 illustrates air door 1140A and 1140B multiple combinations of states conversion process in, motor 130 drives Air door driving wheel 1150A, 1150B rotates (for example, can along be rotated both clockwise and counterclockwise) along different directions.Especially, air door During every next state of group switches, air door driving wheel 1150A turns over different angles, and air door driving wheel 1150B turns over difference Angle；It is preferable that when air door group switches between two states every time, air door driving wheel 1150A drives with air door The angle that wheel 1150B is turned over is identical.In an alternate embodiment of the invention, during many next states of air door group switch, air door driving wheel 1150A can rotate in different directions, and air door driving wheel 1150B also rotates in different directions.For example, working as air door group 1140A, 1140B from first state be switched to the second state when, air door driving wheel 1150A is along rotate counterclockwise (along the side in Fig. 2 Observed to B, similarly hereinafter), air door driving wheel 1150B is along rotate counterclockwise；When air door group 1140A, 1140B is switched to from the second state During the third state, air door driving wheel 1150A is rotated clockwise, and air door driving wheel 1150B is rotated clockwise；When air door group 1140A, 1140B from the third state be switched to four states when, air door driving wheel 1150A is rotated clockwise, air door driving wheel 1150B is rotated clockwise.Correspondingly, motor control program is programmed for so that motor operates to realize by way of expectations The expected rotation mode of air door driving wheel, and the expecting state of corresponding air door changes.

In such embodiments, although the programming of motor is increasingly complex, the shape of grooved tracks can be with more flexible Ground configuration, and the state change mode of air door 1140A, 1140B of the air-supply arrangement is also more flexible.Especially, can basis It is actually needed the program of modification motor such that it is able in the case of the structure for not changing drive mechanism, do not change particularly recessed In the case of the shape of groove track 1151A, 1151B, motor driver is changed, so as to the different conditions for realizing air door group change Sequentially.

With continued reference to Figure 11, when the closing of air door driving wheel 1150A control air doors 1140A and opening, grooved tracks 1151A Change between radius R11 and R12.Air door driving wheel 1150A receives torque from motor, and torque is driven via air door Lever is exported to air door 1140A.The constant torque of air door driving wheel 1150A outputs, and R11<R12, therefore when air door drive rod On post 1161A when moving closer to radius R11, the arm of force at center of the post away from air door driving wheel 1150A is shorter, so as to produce Power is bigger；When the post 1161A on air door drive rod moves closer to radius R12, center of the post away from air door driving wheel 1150A The arm of force is more long, so that the power for producing is smaller.

Similarly, when air door driving wheel 1150B controls the closing of air door 1140B and opens, grooved tracks 1151B is in radius Change between R13 and R14.Air door driving wheel 1150B receives torque from motor, and torque is defeated via air door drive rod Go out to air door 1140B.The constant torque of air door driving wheel 1150B outputs, and R13<R14, therefore when the post on air door drive rod When 1161B moves closer to radius R13, the arm of force at center of the post away from air door driving wheel 1150B is shorter, so that the power for producing is got over Greatly；When the post 1161B on air door drive rod moves closer to radius R14, the arm of force at center of the post away from air door driving wheel 1150B It is more long, so that the power for producing is smaller.

Therefore, when air door 1140A, 1140B nearly closed position, the power for being delivered to post 1161A, 1161B is bigger；Work as wind When door 1140A, 1140B are close to open position, the power for being delivered to post 1161A, 1161B is smaller.Apply at air door closed position Larger power, ensure that the raised brim at air door and air door framework is compressed, it is ensured that under the closed position of air door, air door and The excellent sealing of raised brim.

Figure 12 A and 12B schematically show and move to various location in grooved tracks 1151A in post 1161A and apply The power being applied thereto.The plurality of different position is represented with L1-L6, and is applied to post at the plurality of diverse location L1-L6 The variation tendency of the power on 1161A shows in Figure 12 B.Be can be seen that from Figure 12 A-12B and as described above be applied to post The variation tendency of the change in location of power on 1161A with the post in grooved tracks 1151A.

The above is only exemplary embodiment of the invention, not for limiting the scope of the invention, this hair Bright protection domain is determined by appended claim.

It will be appreciated by persons skilled in the art that each feature in the of the invention multiple embodiments being outlined above Can correspondingly save, add or combine in any way.For example, the driving for driving air door described with reference to Fig. 9-12 Another embodiment of mechanism can be used in combination with the preferred embodiment of the air-supply arrangement 100 described with reference to Fig. 1-8；Air door group The state change order of 1140A, 1140B under the driving of air door driving wheel 1150A, 1150B can be substituted by air door driving wheel The state change of the air door group that 150A, 150B drive sequentially is applied in the air-supply arrangement 100 of Fig. 1-8, otherwise or.These Arbitrary combination is without departing from protection scope of the present invention.
