In a preferred embodiment, radius R1 is equal with R3, and radius R2 is equal with R4, and drives air door 140A and 140B Drive mechanism be integrally arranged symmetrically relative to motor 130 and power source input gear 131 relative to longitudinal direction X, so as to wind Door 140A and 140B turns over identical angle when changing between the open and closed positions.
When air door 140A and 140B multiple combinations of states are shown in the table that Fig. 7 is listed, air door drive rod 160A, 160B and air door driving wheel 150A, 150B state.In the figure 7, framework 110 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 is seen from front to back along the longitudinal direction is shown in Fig. 7, shows air door driving wheel 150A grooved tracks Multiple states that 151A and air door drive rod 160A coordinates, and show air door driving wheel 150B grooved tracks 151B and wind Multiple states that door drive rod 160B coordinates.In Fig. 7 view, although post 161A on air door drive rod 160A, 160B, 161B is invisible between air door drive rod and air door driving wheel, but in order to be clearly shown matching relationship, with overstriking Circle schematically show the position of post 161A, 161B in grooved tracks.It should be appreciated that the post 161A shown, 161B is only schematical effect, and in no way limits size and/or the position of post.
Air door 140A and 140B multiple combinations of states 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.The initial position of described in the text refers to post 161A, 161B in grooved tracks 151A, 151B In position when being in initial end.Now, opening positions of the post 161A in grooved tracks 151A in radius for R1, post 161B In the opening position that radius is R3 in grooved tracks 151B, air door 140A, 140B are in closed position, from without air-flow Flowed out via air stream outlet 101A, 101B.
In the second state, air door driving wheel 150A turns over α 1 relative to first state, i.e. air door driving wheel 150A is relative In initial position rotational angle α 1；Air door driving wheel 150B turns over β 1 relative to first state, i.e. air door driving wheel 150B is relative In initial position rotational angle β 1.Now, post 161A is transformed into radius from the position that radius is R1 in grooved tracks 151A and is R2 opening position, and opening positions of the 161B in grooved tracks 151B still in radius for R3；So as to which air door 140A is 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, air door driving wheel 150A turns over α 2 relative to the second state, i.e. air door driving wheel 150A is relative 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 relative to the second state Relative to initial position rotational angle β 1+ β 2.Now, positions of the post 161A in grooved tracks 151A still in radius for R2 Place, and 161B is transformed into the opening position that radius is R4 in grooved tracks 151B from the position that radius is R3；So as to air door 140A Still in open position, and air door 140B is converted to open position from closed position, now air-flow via air stream outlet 101A, 101B flows out.
In the 4th state, air door driving wheel 150A turns over α 3 relative to the third state, i.e. air door driving wheel 150A is relative 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, positions of the post 161A in grooved tracks 151A from radius for R2 Put the opening position for being transformed into that radius is R1, and opening positions of the post 161B in grooved tracks 151B still in radius for R4；So as to Air door 140A is converted to closed position from open position, and air door 140B, still in closed position, 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 states for air door group 140A, 140B that Fig. 7 is shown.According to the summary of table 1, and with reference to showing in figure 7 The multiple state embodiments gone out, air door drive wheel group 150A, 150B often turn 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 Each in 150A, 150B turns over identical angle respectively, i.e. α 1, α 2, α 3 are identical angle, 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 equal angular, i.e. α 1 is 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 be 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 angle when air door group switches between different conditions, i.e. α 1 and β 1 is not 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, only protect by an 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, in every next state switching of air door group, only the radius of the grooved tracks where a post occurs Change, the radius of the grooved tracks at another post place does not change.So as to according to the grooved tracks at two posts places The change successively of radius, realize 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 of motor output be lost it is smaller.It 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 for driving the moment of torsion that throttle condition changes 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, and so as to which drive mechanism is hardly damaged, and service life extends.
In alternate embodiments, it can also use and two air doors 140A, 140B are realized during the switching per next state while are moved The scheme of work.Such scheme can configure the order between a variety of throttle conditions of air-supply arrangement for greater flexibility；But it will cause The power increase consumed when two door openings and closing, so that the power increase of output needed for motor, possible increase The cost and volume of motor.
In scheme of the present utility model, in air-supply arrangement 100, two air door driving wheels 150A, 150B are relative to drive Dynamic motor 130 is arranged symmetrically, and is driven by the only one motor 130.Two air doors are controlled using single motor simultaneously Combinations of states, cost can be reduced, 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, air door driving wheel 150A, 150B grooved tracks 151A, 151B will apply along vertical on post 161A, 161B The component of direction Z power, so that air door drive rod 160A, 160B have the trend for deviateing transverse direction Y movement.Air door drives The cooperation of guide groove limiting section 121A, 121B on guide groove 163A, 163B and framework 110 on bar 160A, 160B, and/or The association of another guide groove limiting section on another guide groove 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.
Referring again to Fig. 7, 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 from being rotated automatically towards open position.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 air door driving wheel 150A controls air door 140A closing 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 as to which caused power 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 longer, So as to which caused power is smaller.
Similarly, when air door driving wheel 150B controls air door 140B closing and opening, grooved tracks 151B is in radius R3 Change between R4.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 as to which caused power 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 longer, so as to caused power 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 air door 140A, 140B opening and closing position, shows drive mechanism The view that X is seen from back to front (along direction A in Fig. 2) in a longitudinal direction.Air door 140A revolves between the open and closed positions Gyration θA, air door 140B anglec of rotation θ between the open and closed positionsB.In a preferred embodiment, θAWith θBIt is equal.Such as Shown in Fig. 8, θA/θBIt is less than 90 ° of acute angle.Preferably, θA/θBIn the range of 70 ° to 90 °.It is highly preferred that θA/θBSet For 80 ° of angle.If by the anglec of rotation θ of air doorA/θBSelectively too small (being, for example, less than 70 °), then air door length can be caused to increase Add, air door deadweight is consequently increased, while when cold wind air-flow is conveyed, because the length increase of air door will cause Wind power propelling wind The driving part torque increase required when increasing and causing door opening and close of Men Shiyin brachiums；In addition, with door-plate length Increase, overall distance of the air-supply arrangement along air current flow direction lengthen, cause volume to increase, may be deposited in actual production process The waste of material the problem of, 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 Demonstrate,prove excellent sealing of the air door in end.If by the anglec of rotation θ of air doorA/θBSelect as excessive (being greater than 90 °), possibility Cause the transmission device in drive mechanism (for example, air door drive rod 160A and air door actuator 170A, and air door drive rod 160B and air door actuator 170B) between the increase of cooperation stroke, (for example, air door driving wheel 150A, 150B and/or air door drive The size needs of lever 160A, 160B design larger), further cause the increase of the overall volume of air-supply arrangement 100, especially It is the increase of Y length in transverse direction.When the air door anglec of rotation is excessive, air door drive rod (and rack thereon) moves Dynamic distance is elongated, at the same the radius changing rate of the grooved tracks in air door wheel drive surfaces can because rack displacement increase and Change tends to be precipitous, so as to cause the loss of the torque of door-plate motor in switching state to increase.Therefore, air door anglec of rotation θA/θB Reasonable selection can realize motor torque loss it is minimum while, reduce air-supply arrangement 100 volume.
With continued reference to Fig. 8, air door 140A includes panel 143A and the seal 144A being arranged on panel 143A surface. The sunk structure with reinforcement is optionally provided with the panel 143A opposite surface with seal 144A, so as to Manufacture air door 140A material requesteds are reduced on the basis of air door 140A intensity is ensured, mitigate air door 140A weight, and So as to reduce power/torque needed for rotary air valve.Framework 110 includes restriction air-flow at the side for forming air stream outlet 101A and gone out The raised brim 122A of mouth 101A shape.From figure 2 it can be seen that raised brim 122A is substantially rectangular shape, so as to Limit the air stream outlet 101A of rectangular shape.Under air door 140A closed position, seal 144A engagements are substantially rectangular The raised brim 122A of shape, and partly compressed by raised brim 122A, so as to be fully closed gas channel 101A.
Similarly, air door 140B and air door 140B and raised brim 122B cooperation can also similar mode realize, It will not be repeated here.However, in alternate embodiments, air door 140B can be of different sizes with air door 140A or shape Shape.
In the illustrated embodiment, when air door 140A, 140B change 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 resist wind The opening of door；And when air door is changed from open position to closed position, air-flow tends to further press 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 Door driving wheel 150A, 150B grooved tracks 151A, 151B and air door drive rod 160A, 160B post 161A, 161B cooperation 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 change to open position, Being delivered to post 161A, 161B larger power helps to overcome the resistance of air-flow；And when air door tends to change to closed position When, air-flow tends to push air door to closed position, so as to further help in the closing of air door and sealing, and transmits simultaneously Post 161A, 161B it is less try hard to avoid exempt from air door respective bump edge hit with larger impulsive force, reduce to a certain extent Noise.
In alternate embodiments, air door is arranged to, and when air door is closed, air-flow has air door The trend pushed to open position.In such embodiments, sector gear 171A, 171B angle of engagement could be arranged to be more than The angle, θ that air door 140A, 140B are rotated through when closingA/θB, so as to which sector gear can reach closed position laggard one in air door Step ground driving air door compresses to closing direction, to realize more closely sealing.
In the air-supply arrangement 100 according to exemplary embodiment of the present utility model, for driving air door 140A, 140B to exist The drive mechanism changed between open position and closed position is wholly received in the recess of drive mechanism acceptance division 112, and The recess is closed by protecgulum 200 so that drive mechanism is accommodated in the space of base closed, and with for airflow Airflow portion 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 drive mechanism is avoided to be exposed in cold air air-flow.As described above, drive mechanism multiple power transmissions and Its joint, lubricant, such as lubricating oil or lubricating grease can be provided with, 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 be waved too quickly due to air-flow blow-through Hair, so as to avoid caused by lacking lubricant Poewr transmission mechanism to seize up or noise generation, 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 can greatly shorten manufacture Between and cost.In addition, the installation process of symmetrical member is also more simple, it is not error-prone.

Figure 10 A show air door driving wheel 1150A top view and front view.Air door driving wheel 1150A, which has, to be used to connect Receive and drive air door drive rod 1160A post 1161A grooved tracks 1151A.In the illustrated embodiment, grooved tracks 1151A pivot and air door driving wheel 1150A rotation axis coincident.Specifically, grooved tracks 1151A has two not Same orbit radius R11 and R12.When air door drive rod 1160A post 1161A is in orbit radius in grooved tracks 1151A For R11 opening position when, air door 1140A is in the closed position；When air door drive rod 1160A post 1161A is in grooved tracks When in 1151A in opening position of the orbit radius for R12, air door 1140A is in an open position.
Similarly, Figure 10 B show air door driving wheel 1150B top view and front view.Air door driving wheel 1150B has For the grooved tracks 1151B for the post 1161B for receiving and driving air door drive rod 1160B.Specifically, grooved tracks 1151A and 1151B has different shapes, so that 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 combine.Grooved tracks 1151B pivot and air door driving wheel 1150B rotation axis coincident.Specifically, grooved tracks 1151B has in two different orbit radius R13 and R14.Work as wind When door drive rod 1160B post 1161B is R13 opening position in orbit radius in grooved tracks 1151B, air door 1140B It is in the closed position；When air door drive rod 1160B post 1161B is in the position that orbit radius is R14 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 Drive mechanism with 1140B is integrally relative to motor 1130 and power source input gear 1131 relative to the symmetrical cloth of longitudinal direction X Put, identical angle is turned over when being changed between the open and closed positions so as to air door 1140A and 1140B.
When air door 1140A and 1140B multiple combinations of states are shown in the table that Figure 11 is listed, air door drive rod 1160A, 1160B and air door driving wheel 1150A, 1150B state.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 is seen from front to back along the longitudinal direction is shown in Figure 11, shows air door driving wheel 1150A groove Multiple states that track 1151A and air door drive rod 1160A coordinates, and show air door driving wheel 1150B grooved tracks Multiple states that 1151B and air door drive rod 1160B coordinates.In Figure 11 view, although air door drive rod 1160A, 1160B On post 1161A, 1161B it is invisible between air door drive rod and air door driving wheel, but match somebody with somebody to be clearly shown 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 shown is only schematical effect, and in no way limits 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 switching of group, 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 more next states switching of air door group, air door driving wheel 1150A can rotate in different directions, and air door driving wheel 1150B also rotates in different directions.For example, work 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 by way of expectations, to realize The expected rotation mode of air door driving wheel, and the expecting state change of corresponding air door.
In such embodiments, although the programming of motor is increasingly complex, the shape of grooved tracks can be with more flexible Ground configures, and air door 1140A, 1140B of the air-supply arrangement state change mode are also more flexible.Especially, can basis The program of modification motor is actually needed, so as in the case where not changing the structure of drive mechanism, not change particularly recessed In the case of the shape of groove track 1151A, 1151B, motor driver is changed, so as to realize that the different conditions of air door group become Change order.
With continued reference to Figure 11, when air door driving wheel 1150A controls air door 1140A closing 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 work as 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 caused 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 longer, so as to which caused power is smaller.
Similarly, when air door driving wheel 1150B controls air door 1140B closing and opening, 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 as to which caused power 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 longer, so as to which caused power 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, can ensure that the raised brim at air door and air door framework compresses, ensure under the closed position of air door, air door and The excellent sealing of raised brim.
Figure 12 A and 12B schematically show to move in grooved tracks 1151A in post 1161A and applied at diverse location 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 power on 1161A is shown in Figure 12 B.It can be seen that from Figure 12 A-12B and as described above be applied to post The variation tendency of change in location of the power with the post in grooved tracks 1151A on 1161A.
