Description

Technical Field

[0001] The present invention relates to the field of clothing processing equipment, and in particular to a drying method, a medium, a control device and a double-drum clothing processing equipment. Background Art

[0002] In recent years, the development of clothing processing equipment, such as washing machines, dryers, and washer-dryers, has shown a diversified trend. With the improvement of people's living standards, users' demand for clothing processing equipment has gradually increased, and double-drum clothing processing equipment has gradually become an important research and development direction.

[0003] In the related art, both drums of a twin-drum drying device have a drying function. However, in special scenarios, when one of the drums is drying, and the user has an urgent need to dry a small amount of clothes and uses the other drum to dry a small amount of clothes, the twin-drum clothing processing device cannot automatically optimize the drying control logic and cannot meet the user's special needs.

Those skilled in the art can understand that the words "first", "second" and the like do not limit the quantity and execution order, and the words "first", "second" and the like do not limit them to be necessarily different.

[0057] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0058] In the related art, in a double-drum laundry processing device, both drums have a drying function. When one drum is in the drying state, the other drum enters the drying state. If the drum that enters the drying state later dries a small load, it means that the user has an urgent need to dry a small load. However, the current double-drum laundry processing device cannot flexibly adjust the drying control logic of the two drums and cannot meet the special drying needs of users.

[0059] In order to solve the above technical problems, the present embodiment proposes a drying method for a double-drum laundry processing device, the double-drum laundry processing device comprising a first drum, a second drum and a common drying module, the common drying module is used to generate hot air and can transport the hot air to the first drum and / or the second drum, and absorb moisture in the hot air recovered from the first drum and / or the second drum, the drying method comprising:

[0060] receiving a drying program instruction of the first drum and determining the operation status of the second drum;

[0062] When the load level of the first drum is a light load level, the second drum is controlled to suspend drying, the first drum is controlled to dry first, and after the first drum finishes drying, the second drum is controlled to continue drying.

[0063] In the drying method of this embodiment, when the first drum enters the drying process and the second drum is in the drying process, the load level of the first drum that enters the drying process is determined to determine whether the user has an urgent drying need. When the load level of the first drum is a low load level, it indicates that the user has an urgent need to dry a small amount of load through the first drum. At this time, the drying of the second drum is suspended, and the first drum is dried first, so that the heat generated by the shared drying module is concentratedly input into the first drum to accelerate the drying of the first drum, thereby meeting the user's urgent need to dry a small amount of load. After the drying of the first drum is completed, the second drum is dried separately. Compared with drying the first and second drums at the same time, the drying time of the second drum is not significantly extended, and the drying effect of the second drum is also guaranteed.

[0064] The technical solution of this embodiment is described in detail below in conjunction with the accompanying drawings. The following implementation modes and examples may be combined with each other if there is no conflict.

[0065] First, the structure of the implementation body of the drying method of this embodiment is briefly introduced.

The double-drum laundry processing device includes a first drum 1, a second drum 2 and a common drying module, and the common drying module is used to generate hot air and can transport the hot air to the first drum 1 and / or the second drum 2, and absorb moisture in the hot air recovered from the first laundry drum and / or the second drum 2.

[0067] Specifically, the first drum 1 and the second drum 2 are stacked in the housing from top to bottom, the first drum 1 is provided with a first air inlet and a first air outlet, and the second drum 2 is provided with a second air inlet and a second air outlet. The common drying module is respectively introduced into the first drum 1 and the second drum 2 through the first air inlet and the second air inlet, and absorbs moisture in the hot air recovered from the first drum 1 and the second drum 2 through the first air outlet and the second air outlet.

[0068] The shared drying module includes an air duct assembly, a fan component 83 and a heating module. The air duct assembly includes a shared air duct 9, a first air inlet duct 4, a first air outlet duct 6, a second air inlet duct 5, a second air outlet duct 7, a first air door and a second air door. The first air inlet duct 4 connects the first air inlet with the air outlet end of the shared air duct 9, the first air outlet duct 6 connects the first air outlet with the air inlet end of the shared air duct 9, the second air inlet duct 5 connects the second air inlet with the air outlet end of the shared air duct 9, and the second air outlet duct 7 connects the second air outlet with the air inlet end of the shared air duct 9. The shared air duct 9 is provided at the first Between the first tube 1 and the second tube 2, a first air gate is arranged at the air outlet end of the common air duct 9, and the first air gate is constructed to connect one of the first air inlet duct 4 and the second air inlet duct 5 with the common air duct 9, or to connect both the first air inlet duct 4 and the second air inlet duct 5 with the common air duct 9; a second air gate is arranged at the air inlet end of the common air duct 9, and the second air gate is constructed to connect one of the first air outlet duct 6 and the second air outlet duct 7 with the common air duct 9, or to connect both the first air outlet duct 6 and the second air outlet duct 7 with the common air duct 9; a fan component 83 is arranged in the common air duct 9.

[0069] The heating method of the heating device can be electric heating or heat pump heating. In one example, the heating device includes a compressor, an evaporator, a throttling device and a condenser, and the compressor is arranged in the space between the shell and the bottom of the second cylinder 2. The evaporator and the condenser are integrated in the two-device box body, and the two-device box body is arranged in the common air duct 9 and is located downstream of the air outlet end of the fan component 83. The condenser is arranged away from the air duct component relative to the evaporator. The compressor, condenser, throttling device and evaporator are connected in sequence to form a refrigerant circulation loop.

[0070] The double-drum laundry processing device further comprises a first temperature detection device 10 and a second temperature detection device 11, wherein the first temperature detection device 10 is arranged at the first air inlet for detecting the temperature of the first air inlet, and the second temperature detection device 11 is arranged at the first air outlet for detecting the temperature of the first air outlet.

[0071] The double-drum laundry processing device further comprises a third temperature detection device 12 and a fourth temperature detection device 13. The third temperature detection device 12 is arranged at the second air inlet for detecting the temperature of the second air inlet. The fourth temperature detection device 13 is arranged at the second air outlet for detecting the temperature of the second air outlet.

[0072] The drying method of the double-drum laundry processing device of this embodiment is described in detail below.

[0073] This embodiment provides a drying method for a double-drum laundry processing device, combining Figure 2 The drying process flow chart of the present invention comprises the following steps:

[0074] S21, receiving a drying program instruction of the first drum, and determining the operating state of the second drum.

[0075] Specifically, after receiving the drying program instruction of the first drum, the double-drum laundry processing device controls the first drum to enter the drying state, and first determines the running state of the second drum. If the second drum is in a non-drying state, such as a washing state or a standby state, the first drum is dried according to the conventional single-drum drying logic. If the second drum is in the drying state, in the subsequent steps, it is necessary to determine whether to control the first drum to dry first in combination with the load level of the first drum.

[0076] S22, when the second drum is in a drying program state, determining the load level of the first drum.

[0077] Specifically, when it is determined that the second drum is in the drying program state, it is necessary to further determine whether the user has an urgent drying need based on the load level of the first drum, and when it is determined that the user has an urgent drying need based on the load level of the first drum, the first drum is controlled to be dried first in the subsequent drying steps.

[0078] S23, when the load level of the first drum is the light load level, the second drum is controlled to suspend drying, the first drum is controlled to dry first, and after the first drum finishes drying, the second drum is controlled to continue drying.

[0079] Specifically, when it is determined that the load level of the first drum is a low load level, it means that the user has an urgent need for drying. At this time, in order to meet the user's urgent need for drying the load of the first drum, the second drum needs to be controlled to suspend drying, and the shared drying module only delivers hot air to the first drum to achieve priority drying of the first drum. Since the load in the first drum is small, the first drum can be dried in a shorter time, so that the user can get dried clothes in a shorter time, improving the user experience.

[0080] In an optional implementation, when the load level of the first drum is multiple load levels, it means that the user has no urgent need to dry the first drum at this time, and there is no need to control the first drum to dry first. At this time, the first drum and the second drum can be controlled to dry simultaneously, and the shared drying module passes the drying airflow into the first drum and the second drum at the same time to achieve simultaneous drying of the loads in the first drum and the second drum.

[0081] In an optional implementation, before executing the steps of controlling the second drum to pause drying and controlling the first drum to prioritize drying, the drying method further includes: first determining the remaining drying time of the second drum; when the remaining drying time of the second drum is greater than the set drying time, executing the steps of controlling the second drum to pause drying and controlling the first drum to prioritize drying.

[0082] Specifically, when it is determined according to the load level of the first drum that the user has an urgent need to dry the clothes through the first drum, it is also necessary to determine the remaining drying time of the second drum. If the remaining drying time of the second drum is greater than the set drying time, it means that the second drum is far from the end of drying. At this time, the drying of the second drum can be suspended, and the first drum can be controlled to dry first to give priority to meeting the user's urgent drying needs.

[0083] If the remaining drying time of the second drum is less than or equal to the set drying time, it means that the second drum is close to the end of drying and is in the late stage of drying. If the drying of the second drum is suspended, the drying efficiency of the second drum will be seriously affected. At this time, the first drum and the second drum continue to dry. When the drying of the second drum is finished, the first drum is close to drying or has been dried, and the need for emergency drying of clothes by the first drum is not significantly affected.

[0084] Exemplarily, the drying time is set to be less than or equal to one third of the preset total drying time of the second drum, and at this time, the drying process of the second drum has reached the late drying stage.

[0085] There are multiple ways to determine the load level of the first drum in this embodiment. One way to confirm the load level is that the user inputs the load level parameters of the first drum through the control terminal. For example, the control panel corresponding to the double-drum clothing processing device and the first drum has "low load" and "high load" buttons related to the load level parameters. Before the user starts drying the first drum, the user selects "low load" or "high load" according to the actual situation of the load to be dried. After starting drying the first drum, the load level parameters of the first drum are determined according to the load level parameters selected by the user.

[0086] Another method of confirming the load level includes pre-storing the correspondence between the load level and the load weight in the control device of the double-drum clothing processing equipment, determining the load weight by weighing the clothing in the first drum, and determining the load level based on the correspondence between the load level and the load weight.

[0087] According to a preferred confirmation method of the load level, determining the load level of the first drum includes: when any one of the following P1 conditions and P2 conditions is met, determining the load level of the first drum to be a multi-load level, and when both the following P1 conditions and P2 conditions are not met, determining the load level of the first drum to be a small-load level, wherein: the P1 condition includes: when the first drum and the second drum are in the drying program at the same time, the inlet air temperature of the second drum satisfies the rule of first decreasing and then increasing; the P2 condition includes: before the first drum enters the drying program, the power of the motor driving the first drum to rotate when the first drum is rotating is greater than or equal to the set value.

[0088] Specifically, when the second drum is drying and the first drum is drying, the shared drying module changes from providing hot air to the second drum alone to providing hot air to both the first drum and the second drum at the same time. At this time, part of the heat enters the first drum through the corresponding air duct. The load level of the first drum is different, and the degree of influence on the inlet air temperature of the second drum is different. The following is a detailed explanation using a heat pump double-drum clothing processing device as an example.

[0089] When the load level in the first cylinder is a multi-load level, the wet and cold air that enters the first cylinder for drying later will cause the inlet air temperature of the second cylinder that enters the drying earlier to drop instantly. In order to ensure the drying effect of the second cylinder, the compressor works, and the inlet air temperature of the second cylinder will show an upward trend after a period of time. However, if the first cylinder is a low-load level close to an empty cylinder, the evaporator absorbs less heat, the compressor suction temperature is low, the overall temperature of the heat pump system is reduced, and the inlet air temperature of the second cylinder will not show a trend of first decreasing and then increasing. Therefore, one of the judgment conditions for determining whether the first cylinder is at a multi-load level or a low-load level can be determined based on the change in the inlet air temperature of the second cylinder after the first cylinder enters the drying.

[0090] In order to improve the accuracy of the load level judgment in the first drum, this embodiment is further combined with the weight detection result of the first drum before starting drying. Since the motor operating power is positively correlated with the load weight, when the first drum is in the rotating state, when the motor power driving the first drum to rotate is greater than or equal to the set value, it means that the load level of the first drum is a multi-load level at this time, which is used as one of the judgment conditions for judging whether the first drum is a multi-load level or a low-load level. For example, in the empty drum state, the motor power is about 3W when the first drum rotates. When the motor power P is detected to be less than 10W for 5s during the motor operation, it is determined that it is an empty drum or very light load situation.

[0091] This embodiment accurately determines the load level of the first drum by combining the change of the air inlet temperature of the second drum and the value of the motor power of the first drum that enters the drying later, so as to accurately judge whether the user has an urgent drying demand.

[0092] Wherein: the air inlet temperature of the second drum satisfies the rule of first decreasing and then increasing, including: the air inlet temperature of the second drum first decreases to the first set temperature, and after the set time, the air inlet temperature of the second drum increases to the second set temperature, wherein the second set temperature = the first set temperature ± the set value. Exemplarily, when the first drum enters the drying process during the second drum drying process, the air inlet temperature of the second drum will instantly decrease by the first set temperature ΔT. If the load level of the second drum is a multi-load level, the air inlet temperature of the second drum will rise to ΔT ± the set value within the set time t, and the set value is, for example, 3°C.

[0093] The drying method of this embodiment is described in detail below with reference to a specific example.

[0094] Reference Figure 3 The drying process flow chart includes the following steps:

[0095] S31, start drying in drum A;

[0096] S32, drying in drum B is added during the drying process of drum A;

[0097] S33, detecting the air inlet temperature of tube A and the load weight of tube B;

[0098] S34, judging whether the first condition is met: the air inlet temperature of cylinder A does not rise to ΔT±3°C within the set time t;

[0099] S35, determine whether condition 2 is met: the motor power P is detected to be less than 10W for 5 seconds

[0100] S36, determining that the remaining drying time of drum A is greater than one third of the preset total drying time T0;

[0101] S37. If S34, S35, and S36 are satisfied at the same time, the drying of drum A is suspended, and drum B is dried first. After drum B is dried, drum A is continued to be dried.

[0110] The structure of the air distribution assembly is introduced below with respect to different implementation methods.

[0111] In the first embodiment of the air distribution component:

[0112] like Figure 5a to Figure 5h As shown, the air distribution assembly includes:

[0113] The air-dividing shell 2 is formed with a main air duct 231, a main air outlet 241 is formed at one axial end of the main air duct 231, and a plurality of branch air outlets 242 are formed on the side wall of the main air duct 231; the main air outlet 241 and the branch air outlet 242 are both connected to the main air duct 231; specifically, the air-dividing shell 2 includes a main shell 21 and a plurality of branch shells 22, the main shell 21 is a cylindrical structure, the plurality of branch shells 22 are arranged at intervals along the circumference of the main shell 21 on the outside of the main air duct 231, and each branch shell 22 is formed with a branch air duct 232, and the plurality of branch air ducts 232 and the plurality of branch air outlets 242 are connected one-to-one.

[0114] The first wind distribution frame 31 and the second wind distribution frame 32 are both located in the main wind duct 231 and are arranged in the following manner: the first wind distribution frame 31 and the second wind distribution frame 32 can rotate synchronously around the center line of the main wind duct 231, and the second wind distribution frame 32 can slide along the radial direction of the main wind duct 231 relative to the first wind distribution frame 31; a baffle 33 is arranged at one end of the second wind distribution frame 32 away from the first wind distribution frame 31, and the baffle 33 can open or close any branch air outlet 242 as the second wind distribution frame 32 rotates; the baffle 33 is close to the first wind distribution frame 31, and the baffle 33 is arranged at the end of the second wind distribution frame 32 away from the first wind distribution frame 31, and the baffle 33 can open or close any branch air outlet 242 as the second wind distribution frame 32 rotates; the baffle 33 is close to the first wind distribution frame 31, and ... A seal 36 is provided on one side of the side wall near the main air duct 231; the seal 36 is made of rubber material and is nested on the baffle 33; specifically, the baffle 33 is arc-shaped, and the baffle 33 and the main air duct 231 are coaxially arranged; the baffle 33 can close one of the multiple branch air ports 242 and open the other branch air ports 242 or open all the branch air ports 242; when the branch air ports 242 are opened, the movement of the first air distribution frame 31 is controlled to make the baffle 33 move with the second air distribution frame 32, and the opening size of the branch air ports 242 can be adjusted.

[0115] The second air distribution frame 32 is provided with a first state and a second state; when the second air distribution frame 32 is in the first state, the second air distribution frame 32 is close to the center line of the main air duct 231, the baffle 33 is far away from the side wall of the main air duct 231, and the seal 36 can open any branch air outlet 242; when the second air distribution frame 32 is in the second state, the second air distribution frame 32 is far away from the center line of the main air duct 231, the baffle 33 is close to the side wall of the main air duct 231, and the seal 36 can seal any branch air outlet 242. Further, a telescopic mechanism is provided between the first air distribution frame 31 and the second air distribution frame 32; during the rotation of the second air distribution frame 32 with the first air distribution frame 31, under the action of the telescopic mechanism, the second air distribution frame 32 can be converted between the first state and the second state, thereby adjusting the radial distance between the first air distribution frame 31 and the second air distribution frame 32 in the main air duct 231.

[0116] The specific structure of the first air distribution frame 31 and the second air distribution frame 32 is described below. The first air distribution frame 31 includes an A frame segment 312 and a B frame segment 311 which are sequentially arranged from the inside to the outside along the radial direction of the main air duct 231. The A frame segment 312 is rotatably arranged in the main air duct 231 around the center line of the main air duct 231, and the B frame segment 311 extends along the radial direction of the main air duct 231. The A frame segment 312 and the B frame segment 311 are connected; the A frame segment 312 and the B frame segment 311 are integrally formed.

[0117] The second air distribution frame 32 includes a C frame segment 321 and a D frame segment 322 which are sequentially arranged from the inside to the outside along the radial direction of the main air duct 231, and the C frame segment 321 and the D frame segment 322 are integrally formed, and the C frame segment 321 extends radially along the main air duct 231, and the D frame segment 322 is connected to the C frame segment 321; the side of the D frame segment 322 away from the C frame segment 321 is an arc-shaped structure and is provided with a baffle 33; the baffle 33 can be integrally formed with the second air distribution frame 32; the B frame segment and the C frame segment are slidably connected by a sliding structure, and one of the A frame segment 312 and the B frame segment 311 is connected to one of the C frame segment 321 and the D frame segment 322 by a telescopic mechanism; when the first air distribution frame 31 and the second air distribution frame 32 rotate synchronously, the first air distribution frame 31 can slide relative to the second air distribution frame 32 in the radial direction of the main air duct 231.

[0118] The following is an explanation of the specific method of switching the second air distribution frame 32 between the first state and the second state. The telescopic mechanism includes an elastic member 41 and a traction rope 42. The elastic member 41 is arranged between the B frame segment 311 and the C frame segment 321. One end of the traction rope 42 can be wound around the A frame segment 312, and the other end of the traction rope 42 is connected to the C frame segment 321 or the D frame segment 322. When the A frame segment 312 is controlled to rotate and one end of the traction rope 42 is wound, the C frame segment 321 is relative to the B frame segment 312. 11 slides and approaches the center line of the main air duct 231, and the elastic member 41 stores energy; at this time, the baffle 33 is away from the branch air outlet 242 along the circumferential and radial directions of the main air duct 231; when the A frame segment 312 is controlled to rotate and one end of the traction rope 42 is loosened, the elastic member 41 releases energy, and under the action of the elastic member 41, the C frame segment 321 slides relative to the B frame segment 311 and moves away from the center line of the main air duct 231; at this time, the baffle 33 is close to the branch air outlet 242 along the circumferential and radial directions of the main air duct 231.

[0119] Furthermore, one of the B frame segment 311 and the C frame segment 321 is formed with a sliding column, and the other is formed with a sliding hole; the sliding column and the sliding hole cooperate to make the B frame segment 311 and the C frame segment 321 slidingly connected; the sliding column is formed with a mounting hole, the mounting hole and the sliding hole are connected, a part of the elastic member 41 is arranged in the mounting hole, and the other part is arranged in the sliding hole; when the C frame segment 321 slides relative to the B frame segment 311, the elastic member 41 can be elastically deformed in the mounting hole and the sliding hole; preferably, the B frame segment 311 is formed with a sliding column, the C frame segment 321 is formed with a sliding hole, and the elastic member 41 is a spring.

[0120] The following is a further explanation of the driving structure required for the rotation of the turntable 43. The A frame segment 312 is provided with a turntable 43 that can rotate around the center line of the main air duct; the connection position between the traction rope 42 and the A frame segment 312 and the center line of the main air duct 231 are spaced apart in the radial direction of the A frame segment 312. The A frame section 312 is formed with a plurality of first baffle ribs 313, and the plurality of first baffle ribs 313 are arranged at intervals along the circumference of the A frame section 312; the turntable 43 is formed with a plurality of second baffle ribs 431, and the plurality of second baffle ribs 431 are arranged at intervals along the circumference of the turntable 43; the first baffle ribs 313 and the second baffle ribs 431 both extend radially along the main air duct 231; when the A frame section 312 rotates, the first baffle ribs 313 and the second baffle ribs 431 cooperate to rotate the turntable 43, and then one end of the traction rope 42 can be wound around the turntable 43, and under the action of the traction rope 42, the second air distribution frame 32 slides relative to the first air distribution frame 31 in a direction close to the center line of the main air duct 231; or one end of the traction rope 42 is loosened on the turntable 43, and under the action of the elastic member 41, the second air distribution frame 32 slides relative to the first air distribution frame 31 in a direction away from the center line of the main air duct 231.

[0121] When the baffle 33 is at the branch air outlet 243, the turntable 43 will not be entangled with the traction rope 42, so the compression of the elastic member 41 will not increase and it will be in a natural extrusion state, and the sealing member 36 and the side wall of the main air duct 231 have an interference fit, which can squeeze the branch air outlet 243 to achieve a sealing effect; when the turntable 43 is wrapped around the traction rope 42, the compression of the elastic member 41 will increase, reducing the radial distance between the first air distribution frame 31 and the second air distribution frame 32 in the main air duct 231, and increasing the distance between the baffle 33 and the side wall of the main air duct 231. Therefore, when the baffle 33 rotates, there will be no friction between the sealing member 36 and the side wall of the main air duct 231, which can reduce the wear of the sealing member 36 and reduce problems such as abnormal noise caused by friction.

[0122] The angle between the first retaining rib 313 and the second retaining rib 431 is related to the distance between the connection position and the center line of the main air duct and the outer diameter of the turntable 43. When the traction rope 42 is in a natural unwound state, the point where the traction rope 42 is connected to the turntable 43 is the rotation origin; when the traction rope 42 is wound around the turntable 43, the traction rope 42 will be wound around the periphery of the turntable 43, and the circumference of the wound turntable 43 is the compression amount of the control elastic member 41, so the certain angle is calculated based on the circumference of the wound turntable 43 and the diameter of the turntable 43; specifically, the second retaining rib 431 will be set on both sides of the rotation origin on the turntable 43 according to the calculated certain angle, that is, the length of the traction rope 42 to be wound, and the first retaining rib 313 will also be designed on both sides of the A frame section 312, and the distance between the first retaining rib 313 and the second retaining rib 431 is also the angle corresponding to the length of the traction rope 42 to be wound.

[0123] The radial distance between the C frame segment 321 and the B frame segment 311 in the main air duct 231 is related to the connection position between the traction rope 42 and the A frame segment 312, that is, by adjusting the connection position between the traction rope 42 and the A frame segment 312, the effective traction length of the traction rope 42 can be adjusted, and then the radial distance between the C frame segment 321 and the B frame segment 311 in the main air duct 231 can be adjusted; therefore, the connection position between the traction rope 42 and the A frame segment 312 is designed to be adjustable; when the second air distribution frame 32 is in the second state, by adjusting the connection position between the traction rope 42 and the A frame segment 312, the distance between the baffle 33 and the side wall of the main air duct 231 can be adjusted, and then the sealing degree of the seal 36 to the branch air outlet 242 can be adjusted.

[0124] In addition, an axial hole is formed at the other axial end of the main air duct 231; the air distribution assembly also includes a drive motor 35 and a limit frame 34, the drive motor 35 is arranged on the outside of the air distribution shell 2 and at one end away from the main air outlet 241, and the output shaft of the drive motor 35 passes through the axial hole and is connected to the turntable drive; when the drive motor 35 drives the turntable 43 to rotate, the A frame segment 312 rotates under the action of the first retaining rib and the second retaining rib; the limit frame 34 is arranged in the main air duct 231 and the limit frame 34 abuts against the A frame segment 312, which is used to play an axial limiting role on the A frame segment 312; specifically, the limit frame 34 is Z-shaped.

[0125] When the control driving motor 35 drives the turntable 43 to rotate, the A frame segment 312 rotates under the action of the first baffle 313 and the second baffle 431, and then drives the B frame segment 311, the C frame segment 321 and the D frame segment 322 to rotate; the traction rope 42 is wrapped around the periphery of the turntable 43, so that the radial distance between the B frame segment 311 and the C frame segment 321 in the main air duct 231 is reduced, thereby increasing the distance between the baffle 33 and the side wall of the main air duct 231. When the drive motor 35 rotates to the set angle program, it stops rotating and the turntable 43 stops rotating. Then, the drive motor 35 continues to be controlled to rotate in the opposite direction by a certain angle. The certain angle is the angle corresponding to the circumference of the winding turntable 43 calculated as above. Therefore, the turntable 43 rotates to release the traction rope 42. Under the action of the elastic member 41, the radial distance between the first air distribution frame 31 and the second air distribution frame 32 in the main air duct 231 increases, and the distance between the baffle 33 and the side wall of the main air duct 231 decreases. The sealing member 36 seals the branch air outlet; the structure is simple and the cost is low.

[0126] In the second embodiment of the air distribution component:

[0127] like Figures 6a to 6f As shown, the air distribution assembly includes:

[0128] The air-dividing shell 2 is formed with a main air duct 231, a main air outlet 241 is formed at one axial end of the main air duct 231, and a plurality of branch air outlets 242 are formed on the side wall of the main air duct 231; the main air outlet 241 and the branch air outlet 242 are both connected to the main air duct 231; specifically, the air-dividing shell 2 includes a main shell 21 and a plurality of branch shells 22, the main shell 21 is a cylindrical structure, the plurality of branch shells 22 are arranged at intervals along the circumference of the main shell 21 on the outside of the main air duct 231, and each branch shell 22 is formed with a branch air duct 232, and the plurality of branch air ducts 232 and the plurality of branch air outlets 242 are connected one-to-one.

[0129] The air distribution frame 31 is rotatably arranged in the main air duct 231; the air distribution frame 31 is formed with a first air distribution frame structure 313 and a second air distribution frame structure 314, and the first air distribution frame structure 313 and the second air distribution frame structure 314 are spaced apart in the radial direction of the air distribution frame 31; a baffle 32 is arranged on the side of the air distribution frame 31 away from the axis of the main air duct 231; a seal 34 is arranged on the side of the baffle 32 close to the side wall of the main air duct 231; the seal 34 is made of rubber material and is nested on the baffle 32; specifically, the baffle 32 is arc-shaped, and the baffle 32 and the main air duct 231 are coaxially arranged; the baffle 32 can close one of the multiple branch air ports 242 and open the other branch air ports 242 or open multiple branch air ports 242; when the branch air ports 242 are opened, the movement of the first air distribution frame 31 is controlled to make the baffle 32 move with the second air distribution frame, and the opening size of the branch air ports 242 can be adjusted.

[0130] The first driving member 41 and the second driving member 42 are formed with a first driving member structure 411 and a second driving member 42; the first driving member structure 411 and the second driving member structure 421 are both arranged in the main air duct 231. The first wind distribution frame structure 313 and the first driving member structure 411 are drivingly connected, so that the first driving member 41 can drive the wind distribution frame 31 to rotate around the axis of the main air duct 231; the second wind distribution frame structure 314 and the second driving member structure 421 are drivingly connected, so that the second driving member 42 can drive the wind distribution frame 31 to slide radially along the main air duct 231; the second driving member 42 can adjust the sliding distance of the wind distribution frame 31 in the radial direction of the main air duct 231. When the air distribution frame 31 rotates and slides, the baffle 32 moves away from the side wall of the main air duct 231, and the seal 34 can open any branch air outlet 242, thereby increasing the radial distance between the seal 34 and the side wall of the main air duct 231 and reducing the friction loss between the seal 34 and the side wall of the main air duct 231; or the baffle 32 moves close to the side wall of the main air duct 231, and the seal 34 can seal any branch air outlet 242, thereby increasing the degree of fit between the seal 34 and the side wall of the main air duct 231 and improving the sealing degree of the seal 34 to the branch air outlet 242.

[0131] The following further describes the first wind distribution frame structure 313 and the first driving member structure 411. The first wind distribution frame structure 313 is a groove structure, and the first driving member structure 411 is a column structure. Both the first wind distribution frame structure 313 and the first driving member structure 411 extend radially along the main air duct 231, and the first driving member structure 411 is arranged in the first wind distribution frame structure 313. The first wind distribution frame structure 313 has a limiting effect on the first driving member structure 411 in the circumferential direction of the main air duct 231, so that the first driving member 41 can drive the wind distribution frame 31 to rotate. The first driving member structure 411 and the first wind distribution frame structure 313 slide in cooperation in the radial direction of the main air duct 231, and then the wind distribution frame 31 can slide relative to the first driving member 41. That is, when the first driving member 41 drives the first wind distribution frame 31 to rotate, the first wind distribution frame 31 can slide radially along the main air duct 231. Further, the cross-sections of the first wind distribution frame structure 313 and the first driving member structure 411 are both waist-shaped.

[0132] The second air distribution frame structure 314 and the second driving member structure 421 are further explained below. The second air distribution frame structure 314 is a column structure, and the second driving member structure 421 is a groove structure; along the extension direction of the second driving member structure 421, the second driving member structure 421 includes a proximal end and a distal end, and the radial distance between the proximal end and the axis of the main air duct 231 is smaller than the radial distance between the distal end and the axis of the main air duct 231; the second air distribution frame structure 314 can slide between the proximal end and the distal end along the second driving member structure 421.

[0133] When the second wind distribution frame structure 314 cooperates with the near-range end, the baffle 32 is close to the side wall of the main air duct 231; when the second wind distribution frame structure 314 cooperates with the remote end, the baffle 32 is close to the axis of the main air duct 231; that is, when the second wind distribution frame structure 314 changes from being coordinated with the near-range end to being coordinated with the remote end, the wind distribution frame 31 can slide along the radial direction of the main air duct 231, so that the baffle 32 gradually approaches the axis of the main air duct 231; when the second wind distribution frame structure 314 changes from being coordinated with the remote end to being coordinated with the near-range end, the wind distribution frame 31 can slide along the radial direction of the main air duct 231, so that the baffle 32 gradually approaches the side wall of the main air duct 231. The first wind distribution frame structure 313 includes a first radial end and a second radial end in the radial direction of the main air duct 231, and the first radial end and the second radial end are respectively located on both sides of the axis of the main air duct 231, the first radial end is located on a side close to the baffle 32, and the second radial end is located on a side away from the baffle 32.

[0134] The radial distance between the first radial end and the axis of the main air duct 231 and the radial distance between the remote end and the axis of the main air duct 231 determine the radial sliding range of the air distribution frame 31 and the maximum radial distance between the baffle 32 and the side wall of the main air duct 231; the radial distance between the first radial end and the axis of the main air duct 231 is designed to be greater than the radial distance between the remote end and the axis of the main air duct 231, so as to increase the radial sliding range of the air distribution frame 31 and the maximum radial distance between the baffle 32 and the side wall of the main air duct 231 when the baffle 32 is away from the branch air port 242; in this way, when the baffle 32 is away from the branch air port 242, the maximum radial distance between the baffle 32 and the side wall of the main air duct 231 is determined by the radial distance between the remote end and the axis of the main air duct 231; therefore, when the baffle 32 rotates, there will be no friction between the seal 34 and the side wall of the main air duct 231, which can reduce the wear of the seal 34 and reduce problems such as abnormal noise caused by friction.

[0135] The radial distance between the second radial end and the axis of the main air duct 231 and the radial distance between the proximal end and the axis of the main air duct 231 determine the radial sliding range of the air distribution frame 31 and the minimum radial distance between the baffle 32 and the side wall of the main air duct 231. The radial distance between the second radial end and the axis of the main air duct 231 is designed to be greater than the radial distance between the proximal end and the axis of the main air duct 231, so as to increase the radial sliding range of the air distribution frame 31 and reduce the minimum radial distance between the baffle 32 and the side wall of the main air duct 231; in this way, when the baffle 32 is close to the branch air port 242, the minimum radial distance between the baffle 32 and the side wall of the main air duct 231 is determined by the radial distance between the proximal end and the axis of the main air duct 231; the sealing member 34 and the side wall of the main air duct 231 have an interference fit, which can squeeze the branch air port 242 to achieve a sealing effect. The second driving member 42 is detachably arranged in the main air duct 231, and the second driving member 42 with a suitable structure can be selected according to actual needs; when the structure of the second driving member 42 is different, the radial distance between the remote end and the axis of the main air duct 231 and the radial distance between the near end and the axis of the main air duct 231 are different, so that the second driving member 42 can be applied to different air distribution shells 2, thereby increasing the scope of application.

[0136] Further, the second driving member structure 421 is annular, that is, the second driving member structure 421 is an annular groove structure; the second driving member structure 421 is arranged around the outside of the first driving member structure 411; the second driving member structure 421 includes a convex arc segment 422 and a concave arc segment 423; the convex arc segment 422 is convex to the axis of the main air duct 231, the concave arc segment 423 is connected to the convex arc segment 422, and the concave arc segment 423 is concave to the side wall of the main air duct 231. The convex arc segment 422 is formed with a near-range end, and the concave arc segment 423 is formed with a far-range end; the second wind distribution frame structure 314 can cooperate with the near-range end when sliding along the convex arc segment 422, and can cooperate with the far-range end when sliding along the concave arc segment 423.

[0137] In some embodiments, multiple convex arc segments 422 and concave arc segments 423 are provided; multiple convex arc segments 422 are arranged at intervals, and a concave arc segment 423 is connected between two adjacent convex arc segments 422; each convex arc segment 422 is formed with multiple proximal ends, and the distance between at least two of the multiple proximal ends and the axis of the main air duct 231 is equal; when the second wind distribution frame structure 314 and the two proximal ends are matched, the degree to which the baffle 32 seals the branch air outlet 242 is close; each concave arc segment 423 is formed with multiple remote ends, and the distance between at least two of the multiple remote ends and the axis of the main air duct 231 is unequal; when the second wind distribution frame structure 314 and the two remote ends are matched, the distance between the baffle 32 and the side wall of the main air duct 231 is different; in this way, the rotation space of the wind distribution frame 31 is larger, and it can be suitable for different seals 34.

[0138] Preferably, the second driving member 42 is a cam, the second driving member 42 and the first driving member 41 are coaxially arranged, and the second driving member 42 is stationary relative to the first driving member 41; a second driving member structure 421 is formed on the inner side of the second driving member 42; when different parts of the second air distribution frame structure 314 and the cam cooperate, the radial distance between the baffle 32 and the side wall of the main air duct 231 is different. The second driving member 42 drives the air distribution frame 31 to slide radially along the main air duct 231, so that when the baffle 32 approaches the branch air port 242, the sealing member 34 and the side wall of the main air duct 231 have an interference fit, which can squeeze the branch air port 242 to achieve a sealing effect; the second driving member 42 drives the air distribution frame 31 to slide radially along the main air duct 231, so that when the baffle 32 moves away from the branch air port 242, the distance between the baffle 32 and the side wall of the main air duct 231 is increased. Therefore, when the baffle 32 rotates, there will be no friction between the sealing member 34 and the side wall of the main air duct 231, which can reduce the wear of the sealing member 34 and reduce problems such as abnormal noise caused by friction.

[0146] When the driving member 35 drives the inner connecting rod to rotate, the air distribution frame 31 moves under the action of the elastic member and the outer connecting rod, and then the baffle 33 can open or close any branch opening of the air distribution chamber.

[0147] Specifically, the air distribution shell 2 includes a main shell 21 and a branch shell 22. The main shell 21 is a cylindrical structure and is formed with an air distribution chamber 211; an axial end of the main shell 21 forms a main opening 212 of the air distribution chamber, and the other axial end of the main shell 21 forms an axial hole; the driving member 35 is a driving motor, the driving member 35 is arranged outside the air distribution chamber 211, and the output shaft 351 passes through the axial hole and enters the air distribution chamber 211; a plurality of branch shells 22 are arranged at intervals along the circumference of the main shell 21 on the outside of the air distribution chamber 211, and each branch shell 22 is formed with a branch air duct, and the plurality of branch air ducts are connected to the plurality of air distribution chamber branch openings one by one; the baffle 33 is close to the air distribution chamber 21 A sealing member 36 is provided on one side of the side wall of 1; the sealing member 36 is made of rubber material and is nested on the baffle plate 33; the baffle plate 33 is in an arc shape, and the baffle plate 33 and the air distribution chamber 211 are coaxially arranged; the baffle plate 33 can close one of the multiple air distribution chamber branch openings and open the other air distribution chamber branch openings or open the multiple air distribution chamber branch openings; when the air distribution chamber branch opening is opened, the baffle plate 33 is moved to adjust the opening size of the air distribution chamber branch opening; the air distribution assembly also includes a limiting frame 34, which is arranged in the air distribution chamber 211 and abuts against the air distribution frame 31, and is used to limit the air distribution frame 31 in the axial direction; specifically, the limiting frame 34 is in a Z shape;

[0148] When the air distribution frame 31 rotates and slides, the baffle 33 moves away from the side wall of the air distribution chamber 211, and the seal 36 can open any branch of the air distribution chamber, thereby increasing the radial distance between the seal 36 and the side wall of the air distribution chamber 211 and reducing the friction loss between the seal 36 and the side wall of the air distribution chamber 211; or the baffle 33 moves close to the side wall of the air distribution chamber 211, and the seal 36 can seal any branch of the air distribution chamber, thereby increasing the degree of fit between the seal 36 and the side wall of the air distribution chamber 211 and improving the degree of sealing of the air distribution chamber branch by the seal 36; the structure is simple and occupies little space; the ventilation modes are diverse and the ventilation volume is adjustable to meet different ventilation needs.

[0149] Furthermore, the baffle 33 includes a first abutment portion 331 and a second abutment portion 332 arranged at intervals along the circumference of the air distribution chamber 211. When the inner connecting rod rotates and the outer connecting rod rotates relative to the inner connecting rod in a first direction under the action of the elastic member, the air distribution frame 31 moves toward the axis of the air distribution chamber 211, and the baffle 33 can open the branch opening of the air distribution chamber; when the outer connecting rod abuts against the first abutment portion 331, the air distribution frame 31 can rotate. When the inner connecting rod rotates and the outer connecting rod rotates relative to the inner connecting rod in a second direction, the outer connecting rod abuts against the second abutment portion 332, causing the air distribution frame 31 to rotate and move toward the side wall of the air distribution chamber 211, and then the baffle 33 can close the branch opening of the air distribution chamber. Among them, the first direction is the direction in which the angle between the outer connecting rod and the inner connecting rod gradually decreases from 180 degrees to 0 degrees, and the second direction is the direction in which the angle between the outer connecting rod and the inner connecting rod gradually increases from 0 degrees to 180 degrees; when the angle between the outer connecting rod and the inner connecting rod decreases, the elastic member stores energy, and the baffle 33 moves toward the axis of the air distribution chamber 211 along with the air distribution frame 31; when the angle between the outer connecting rod and the inner connecting rod increases, the elastic member releases energy, and the baffle 33 moves toward the side wall of the air distribution chamber 211 along with the air distribution frame 31.

[0150] Specifically, the baffle plate 33 has an arc-shaped structure and the baffle plate 33 and the air distribution chamber 211 are coaxially arranged; the first abutment portion 331 is a convex rib, and the second abutment portion 332 is a groove; along the circumference of the baffle plate 33, the first abutment portion 331 is close to the edge of the baffle plate 33, and the second abutment portion 332 is far away from the edge of the baffle plate 33; the extension direction of the first abutment portion 331 and the extension direction of the second abutment portion 332 are both parallel to the axis of the air distribution chamber 211.

[0152] The matching structure of the air distribution frame 31 and the outer connecting rod is further explained. The frame connecting part is a column structure, the connecting rod connecting part is a groove structure, and the extension direction of the connecting rod connecting part is parallel to the axis of the air distribution chamber 211; the cross-sections of the frame connecting part and the connecting rod connecting part are both waist-shaped structures, and the length direction of the waist-shaped structure is the radial direction of the air distribution chamber 211; the inner connecting rod is also formed with an inner connecting column, and an elastic part is connected between the inner connecting column and the frame connecting part.

[0153] The specific structure of the air distribution assembly is further explained below by taking the connecting rod structure including two as an example. The two connecting rod mechanisms are respectively the first connecting rod mechanism 41 and the second connecting rod mechanism 42; along the axial direction of the air distribution chamber 211, the first connecting rod mechanism 41 and the second connecting rod mechanism 42 are respectively arranged on both sides of the air distribution frame 31, and the first frame connecting part 321 and the second frame connecting part 322 are respectively formed on both sides of the air distribution frame 31, and the output shaft 351 is formed with a first shaft section and a second shaft section.

[0154] The inner link of the first link mechanism 41 is the first inner link 411, the outer link of the first link mechanism 41 is the first outer link 412, and the elastic member of the first link mechanism 41 is the first elastic member 413; one end of the first inner link 411 is drivingly connected to the first shaft segment, one end of the first outer link 412 is hingedly connected to the other end of the first inner link 411, the link connecting portion of the first outer link 412 is the first link connecting portion 414, and the first link connecting portion 414 cooperates with the first frame connecting portion 321; the first elastic member 413 connects the first frame connecting portion 321 and the first inner link 411.

[0155] The inner connecting rod of the second connecting rod mechanism 42 is the second inner connecting rod 421, the outer connecting rod of the second connecting rod mechanism 42 is the second outer connecting rod 422, and the elastic member of the second connecting rod mechanism 42 is the second elastic member 423; one end of the second inner connecting rod 421 is drivingly connected to the second shaft segment, one end of the second outer connecting rod 422 is hingedly connected to the other end of the second inner connecting rod 421, the connecting rod connecting part of the second outer connecting rod 422 is the second connecting rod connecting part 424, and the second connecting rod connecting part 424 cooperates with the second frame connecting part 322; the second elastic member 423 connects the second frame connecting part 322 and the first inner connecting rod 411; the first elastic member 413 and the second elastic member 423 are both tension springs.

[0156] Furthermore, the baffle 33 is provided with a retracted state close to the axis of the air distribution chamber 211 and an extended state close to the side wall of the air distribution chamber 211. The switching process of the baffle 33 between the retracted state and the extended state is described in the following two cases. First, when the baffle 33 is in the retracted state and the angle between the outer link and the inner link of the first link mechanism 41 is smaller than the angle between the outer link and the inner link of the second link mechanism 42, the output shaft 351 drives the inner link of the first link mechanism 41 and the inner link of the second link mechanism 42 to rotate. Under the action of the first elastic member 413 and the second elastic member 423, the angle between the first outer link 412 and the first inner link 411 and the angle between the second outer link 422 and the second inner link 421 are increased, and the second outer link 422 abuts the second abutting portion 332, so that the air distribution frame 31 moves toward the side wall of the air distribution chamber 211, and then the baffle 33 is in the extended state.

[0157] The output shaft 351 drives the first inner link 411 and the second inner link 421 to continue to rotate, and the angle between the first outer link 412 and the first inner link 411 continues to increase. Under the action of the first elastic member 413 and the second elastic member 423, the angle between the second outer link 422 and the second inner link 421 increases to 180° and then decreases in the reverse direction, causing the air distribution frame 31 to slide toward the axis of the air distribution chamber 211, and then the baffle 33 is in a retracted state again; when the second outer link 422 abuts against the second abutting portion 332, the air distribution frame 31 rotates.

[0158] Second, when the baffle 33 is in the retracted state and the angle between the first outer link 412 and the first inner link 411 is greater than the angle between the second outer link 422 and the second inner link 421, the output shaft 351 drives the first inner link 411 and the second inner link 421 to rotate, and under the action of the first elastic member 413 and the second elastic member 423, the angle between the first outer link 412 and the first inner link 411 and the angle between the second outer link 422 and the second inner link 421 are increased, and the first outer link 412 abuts against the first abutting portion 331, so that the air distribution frame 31 moves toward the axis of the air distribution chamber 211, and then the baffle 33 is in the extended state.

[0159] The output shaft 351 drives the first inner link 411 and the second inner link 421 to continue to rotate. Under the action of the first elastic member 413 and the second elastic member 423, the angle between the second outer link 422 and the second inner link 421 continues to increase. The angle between the first outer link 412 and the first inner link 411 increases to 180° and then decreases in the reverse direction, causing the air distribution frame 31 to move toward the axis of the air distribution chamber 211, and then the baffle 33 is in a retracted state again; when the first outer link 412 abuts against the first abutting portion 331, the air distribution frame 31 rotates.

[0160] The following further describes the multiple air chamber branch openings including the air chamber B1 branch opening 213 and the air chamber B2 branch opening 214 as an example;

[0161] First, when the air distribution frame 31 is in a retracted state and the radial upper baffle 33 of the air distribution chamber 211 corresponds to the branch opening 213 of the air distribution chamber B1, the angle between the first outer connecting rod 412 and the first inner connecting rod 411 is smaller than the angle between the second outer connecting rod 422 and the second inner connecting rod 421; the output shaft 351 drives the first inner connecting rod 411 and the second inner connecting rod 421 to rotate, and the angle between the first outer connecting rod 412 and the first inner connecting rod 411 and the angle between the second outer connecting rod 422 and the second inner connecting rod 421 are increased, and the second outer connecting rod 422 abuts against the second abutting portion 332, so that the second air distribution frame moves radially outward from the air distribution chamber 211, and then the air distribution frame 31 is in an extended state and closes the branch opening 213 of the air distribution chamber B1.

[0162] The output shaft 351 drives the first inner link 411 and the second inner link 421 to continue to rotate, and the angle between the first outer link 412 and the first inner link 411 continues to increase. The angle between the second outer link 422 and the second inner link 421 increases to 180° and then decreases in the opposite direction, so that the air distribution frame 31 moves radially inwardly of the air distribution chamber 211, and then the air distribution frame 31 is in a retracted state again and opens the branch port 213 of the air distribution chamber B1; when the second outer link 422 abuts against the second abutting portion 332, the air distribution frame 31 rotates.

[0163] Second, when the air distribution frame 31 is in the retracted state and the radial upper baffle 33 of the air distribution chamber 211 corresponds to the air distribution chamber B2 branch 214, the angle between the first outer connecting rod 412 and the first inner connecting rod 411 is greater than the angle between the second outer connecting rod 422 and the second inner connecting rod 421; the output shaft 351 drives the first inner connecting rod 411 and the second inner connecting rod 421 to rotate, and the angle between the first outer connecting rod 412 and the first inner connecting rod 411 and the angle between the second outer connecting rod 422 and the second inner connecting rod 421 are increased, and the first outer connecting rod 412 abuts against the first abutting portion 331, so that the air distribution frame 31 slides radially outward from the air distribution chamber 211, and then the air distribution frame 31 is in the extended state and closes the air distribution chamber B2 branch 214.

[0164] The output shaft 351 drives the first inner link 411 and the second inner link 421 to continue to rotate, and the angle between the second outer link 422 and the second inner link 421 continues to increase. The angle between the first outer link 412 and the first inner link 411 increases to 180° and then decreases in the reverse direction, causing the air distribution frame 31 to slide radially inwardly of the air distribution chamber 211, and then the air distribution frame 31 is in a retracted state again and opens the branch port 214 of the air distribution chamber B2; when the first outer link 412 abuts against the first abutting portion 331, the air distribution frame 31 rotates.

[0165] When the air distribution frame 31 makes the baffle 33 close to the branch opening of the air distribution chamber, the sealing member 36 and the side wall of the air distribution chamber 211 are interference fit, which can squeeze the branch opening of the air distribution chamber to achieve a sealing effect; when the air distribution frame 31 makes the baffle 33 away from the branch opening of the air distribution chamber, the distance between the baffle 33 and the side wall of the air distribution chamber 211 is increased; therefore, when the baffle 33 rotates, there will be no friction between the sealing member 36 and the side wall of the air distribution chamber 211, which can reduce the wear of the sealing member 36 and reduce problems such as abnormal noise caused by friction.

[0166] In the present application, the output shaft 351 of the driving member 35 is coaxially arranged with the first inner connecting rod 411, the second inner connecting rod 421 and the air distribution frame 31, and the assembly sequence is "driving member 35→first inner connecting rod 411→air distribution frame 31→second inner connecting rod 421→limiting frame 34", wherein the first inner connecting rod 411 and the second inner connecting rod 421 are all drivingly connected to the output shaft 351, and the driving member 35 is a stepping motor, and the driving member 35 can control the rotation of the first inner connecting rod 411 and the second inner connecting rod 421; when the first outer connecting rod 412 and the second outer connecting rod 422 are in contact with the baffle 33, the air distribution frame 31 is driven to rotate, and under the action of the elastic member, the air distribution frame 31 moves radially along the air distribution chamber 211, and the extension and contraction of the elastic member is achieved by changing the angle between the outer connecting rod and the inner connecting rod, so the present invention realizes a stepping motor to control the rotation and movement of the air distribution frame 31.
