An air conditioner 2 according to some embodiments of the present application is described below with reference to FIGS. 1-24 .

The air conditioner 2 includes an indoor unit and an outdoor unit. The indoor unit and the outdoor unit are connected by pipelines to transmit refrigerant. The indoor unit includes an indoor heat exchanger and an indoor fan. The outdoor unit includes a compressor, a four-way valve, an outdoor heat exchanger, an outdoor fan and an expansion valve.

The compressor is configured to compress the refrigerant such that the low pressure refrigerant is compressed to form the high pressure refrigerant.

The outdoor heat exchanger is configured to exchange heat between the outdoor air and the refrigerant conveyed in the outdoor heat exchanger. For example, the outdoor heat exchanger works as a condenser in the cooling mode of the air conditioner 2 , so that the refrigerant compressed by the compressor dissipates heat to the outdoor air through the outdoor heat exchanger to be condensed. The outdoor heat exchanger works as an evaporator in the heating mode of the air conditioner 2 , so that the decompressed refrigerant absorbs the heat of the outdoor air through the outdoor heat exchanger and evaporates.

In some embodiments, the outdoor heat exchanger further includes heat exchange fins to expand the contact area between the outdoor air and the refrigerant transported in the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

Outdoor fans provide power for the movement of outdoor air.

The expansion valve is connected between the outdoor heat exchanger and the indoor heat exchanger, and the pressure of the refrigerant flowing through the outdoor heat exchanger and the indoor heat exchanger is adjusted by the opening of the expansion valve to adjust the flow between the outdoor heat exchanger and the indoor heat exchanger. Refrigerant flow between heaters. The flow rate and pressure of the refrigerant circulating between the outdoor heat exchanger and the indoor heat exchanger will affect the heat exchange performance of the outdoor heat exchanger and the indoor heat exchanger. The expansion valve may be an electronic valve. The opening of the expansion valve is adjustable to control the flow and pressure of the refrigerant flowing through the expansion valve.

The four-way valve is connected in the refrigerant circuit, and the four-way valve is configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the air conditioner 2 executes a cooling mode or a heating mode.

The indoor heat exchanger is configured to exchange heat between the indoor air and the refrigerant conveyed in the indoor heat exchanger. For example, the indoor heat exchanger works as an evaporator in the cooling mode of the air conditioner 2 , so that the refrigerant that has dissipated heat through the outdoor heat exchanger absorbs heat from the indoor air through the indoor heat exchanger and evaporates. The indoor heat exchanger works as a condenser in the heating mode of the air conditioner 2 , so that the refrigerant absorbed by the outdoor heat exchanger dissipates heat to the indoor air through the indoor heat exchanger to condense.

In some embodiments, the indoor heat exchanger further includes heat exchange fins to expand the contact area between the indoor air and the refrigerant transported in the indoor heat exchanger, thereby improving the heat exchange efficiency between the indoor air and the refrigerant.

The air conditioner 2 also includes a control device. The control device is configured to control the operating frequency of the compressor, the opening degree of the expansion valve, the rotational speed of the outdoor fan and the rotational speed of the indoor fan. The control device is connected with the compressor, the expansion valve, the outdoor fan and the indoor fan through data lines to transmit communication information.

The control device includes a processor. The processor may include a central processing unit (Central Processing Unit, CPU)), a microprocessor (microprocessor), an application specific integrated circuit (ASIC), and may be configured such that when the processor executes a When the program in the non-transitory computer readable medium is used, the corresponding operations described in the control device are executed. Non-transitory computer-readable storage media may include magnetic storage devices (e.g., hard disk, floppy disk, or tape), smart cards, or flash memory devices (e.g., erasable programmable read-only memory (EPROM), card , stick or keyboard drive).

Generally, the air conditioner 2 controls the flow direction of the air outlet airflow through the following settings: the air guide plate is arranged horizontally and placed outside the air outlet, and the wind is swept up and down by rotating the air guide plate; the air conditioner 2 has built-in longitudinal guide vanes Realize sweeping wind left and right; the air conditioner 2 is horizontally provided with a wind plate with fine holes, so that the air flow passes through the through holes on the wind plate at a low speed;

However, the airflow at the air outlet of the above-mentioned air conditioner 2 is oriented along a straight line, and the air outlet form is single. Since the airflow is oriented along a straight line, and the airflow is in a beam shape, the sense of sweeping is strong, and the user's comfort is poor. The bundled wind makes the indoor airflow flow in a single way, which cannot produce a comfortable wind field with transient changes in wind speed and direction. In addition, the air outlet mode of the air conditioner 2 is single, the air mixing efficiency is low, and the energy consumption is high.

As shown in Figures 2-5, the air conditioner 2 according to some embodiments of the present application includes: an air duct 3 and an oscillator 1, the air duct 3 is a passage for wind to enter and exit, and the wind can enter the air duct 3 , and then discharged into the room through the heat exchange of the heat exchanger to achieve the effect of cooling and heating. The oscillator 1 can achieve self-oscillating air output, which can improve the indoor air mixing efficiency, and can change the indoor steady-state air flow organization form to avoid direct air flow and achieve a natural and comfortable air supply effect.

As shown in Figures 1 to 5, a fan 50 is arranged in the air duct 3, and the fan 50 can rotate, so that the wind outside the air conditioner 2 can be sucked into the air duct 3, and the air duct 3 is provided with a fan 50. The wind after heat exchange can be discharged into the room through the air duct outlet 60 . In addition, the air duct outlet 60 is configured in a contracted shape, so that the wind passing through the air duct outlet 60 can play a beam effect.

As shown in Figures 6-23, the oscillator 1 includes: a housing 10, at least one partition 20, and a driver 30. The housing 10 constitutes the overall shape of the oscillator 1, and can function as a seal to prevent The air flow leaks when passing through the oscillator 1, and a cavity 13 is formed in the casing 10, and the air flow can enter the cavity 13, and at least one partition 20 is arranged in the cavity 13, and after the air flow passes through at least one partition 20 , the airflow in the cavity 13 can be deflected, and a vortex can be formed at the partition 20 to realize the self-oscillating wind of the oscillator 1, so that the indoor air mixing efficiency can be improved, and the indoor steady-state airflow can be changed The organizational form avoids direct blowing of the airflow to achieve a natural and comfortable air supply effect, and the driving part 30 can play a driving role. The driving member 30 may be a motor.

As shown in Figures 13-23, the housing 10 includes: an air inlet 11 and an air outlet 12, the air inlet 11 communicates with the outlet of the air duct, and the cavity 13 communicates with the air inlet 11 and the air outlet 12, so that the air flow can It enters the cavity 13 through the outlet of the air duct and the air inlet 11, and then the air can be discharged from the air outlet 12, and after being deflected, a self-oscillating transient vortex can be formed indoors.

As shown in Figures 13-23, after at least one partition 20 is arranged in the cavity 13, the cavity 13 can be divided into a main flow channel 130 and at least one return flow channel 131, and the two ends of the main flow channel 130 are respectively connected to the inlet flow channel. The tuyere 11 and the air outlet 12 are oppositely arranged, and the inlet 132 of the return passage 131 is defined between the end of the partition 20 adjacent to the air outlet 12 and the housing 10 , and the inlet 132 of the return passage 131 is defined between the end of the partition 20 adjacent to the air inlet 11 and the housing 10 . The outlet 133 of the return channel 131 . That is to say, when the air flow enters the main channel 130 through the air inlet 11, it will flow towards the air outlet 12, and part of the air flow will enter from the inlet 132 of the return channel 131 when it flows to the air outlet 12 due to the obstruction of the housing 10. into the return channel 131, and then return to the main channel 130 from the outlet 133 of the return channel 131.

As shown in Figures 13-23, at least one partition 20 is movably disposed in the cavity 13, the partition 20 has a rotation axis 27, and the rotation axis 27 is located between the partition 20 and the central axis of the housing 10 , the driving part 30 is arranged on the housing 10, so that the position of the driving part 30 can be fixed, so that the driving part 30 can work normally and stably, and the driving part 30 is connected with at least one partition 20, so that the driving part 30 can drive the partition 20 rotate around the axis of rotation 27 lines. The following is an example of the flow principle of the airflow when there are two partitions 20 and the two partitions 20 rotate clockwise together at a point along the centerline of the cavity 13 in the cavity 13 . Wherein, two partitions 20 are arranged at intervals up and down in the cavity 13 .

It should be noted that the partition 20 has a first position 21, a second position 26 and a third position 22. When the partition 20 is in the first position 21, the first end of the partition 20 is adjacent to the air inlet 11, and the second end Adjacent to the air outlet 12, and the distance between the first end of at least one partition 20 and the central axis of the housing 10 is smaller than the distance between the second end and the central axis of the housing 10, the oscillator 1 is oscillating at this time. , when the partition 20 is in the second position 26, the distance between the first end of at least one partition 20 and the central axis of the housing 10 is greater than the distance between the second end and the central axis of the housing 10, and the return channel 131 The outlet 133 of the outlet 133 is in communication with the main channel 130 , and when the partitions 20 are in the third position 22 , the first end of one of the partitions 20 is adjacent to the air outlet 12 , and the second end is adjacent to the air inlet 11 .

As shown in Figure 5, Figure 20 and Figure 21, when the driving member 30 drives the partition 20 to the second position 26, after at least one partition 20 rotates to a certain angle, the first end of the partition 20 is adjacent to the air outlet 12. The second end is adjacent to the air inlet 11, wherein a new main flow channel 130 is formed between at least two partitions 20, and the distance between the first ends of at least two partitions 20 is greater than the distance between the second ends, In this way, the main flow channel 130 is formed in a constricted shape as a whole to ensure that the airflow converges toward the central axis of the casing 10 along the edge, so that the airflow can flow out through the air outlet 12 after passing through the beam.

Certainly, as shown in Fig. 5, Fig. 22 and Fig. 23, when the distance between the second ends of at least two partitions 20 is small, under the premise that the airflow velocity of the air inlet 11 is constant, due to the at least two partitions 20 The distance between the second ends decreases so that the flow velocity is accelerated, at this moment, the beam becomes a jet, and the oscillator 1 as a whole becomes a jet channel, at this time, most of the air flow passes through the partition 20 and then along the edge of the housing 10. When the central axis flows out, a small part of the fluid flows out along the partition 20 in the reverse direction through the partition 20 and the inner walls of the cavities 13 on both sides due to the pressure. jet distance. Wherein, the flow resistance characteristic is jointly determined by the inlet 132 of the cavity 13 , the jet opening formed by the partition 20 , and the outlet 133 of the cavity 13 .

It should be noted that, when the oscillator 1 streams out the wind and the jet out, after the airflow enters the main channel 130, it cannot enter the backflow channel 131 from the inlet 132 of the backflow channel 131, and the airflow can only move in the opposite direction when the jet outflows , enter the return channel 131 from the outlet 133 of the return channel 131, and flow back from the inlet 132 of the return channel 131 to the main channel 130, and mix with the airflow of the main channel 130 to reduce the divergence of the jet and increase the distance of the jet.

As shown in Figure 3, Figure 16 and Figure 17, when the driving member 30 drives the partition 20 to the third position 22, after the upper partition 20 rotates to a certain angle, the first end of the partition 20 is adjacent to the air outlet 12. The second end is adjacent to the air inlet 11, and the second end is slowly approaching the housing 10, so that the outlet 133 of the return passage 131 on the upper side is reduced, and the airflow will move along the wall of the partition 20, wherein the partition 20 and the unmoved partition 20 below form a new main flow passage 130, the main flow passage 130 is contracted as a whole, and its flow direction is V-shaped. The action of the airflow further changes the direction of the airflow, so that when the airflow flows out of the main channel 130, the flow direction is deflected by a certain angle, wherein the deflection angle is the angle between the central axis of the housing 10 and the flow direction of the airflow at the air outlet 12. Based on the above design features, after the upper partition 20 is moved, a directional fluid in an oblique upward direction can be generated at the air outlet 12 of the oscillator 1 .

Similarly, as shown in FIG. 4 , FIG. 18 and FIG. 19 , when the driving member 30 drives the partition plate 20 to the third position 22, after the bottom partition plate 20 rotates to a certain angle, the first end of the partition plate 20 Adjacent to the air outlet 12, the second end is adjacent to the air inlet 11, and the second end is slowly approaching the housing 10, so that the outlet 133 of the lower backflow channel 131 is reduced, and the airflow will move along the wall of the partition 20, wherein , an included angle is formed between the two ends of the partition 20, and the included angle is an obtuse angle, and a new mainstream channel 130 is formed between the partition 20 and the upper partition 20 that has not moved. V-shaped, after the airflow passes through the air inlet 11, it will be guided by the upper side of the front end of the outlet 133 of the cavity 13, so that the direction of the airflow will be further changed, so that the airflow will deflect at a certain angle when it flows out of the main channel 130, wherein the deflection angle is The included angle between the central axis of the casing 10 and the flow direction of the airflow at the air outlet 12 . Based on the above design features, after the lower partition 20 is moved, a directional fluid in an obliquely downward direction can be generated at the air outlet 12 of the oscillator 1 .

Thus, by being provided with the oscillator 1, the oscillator 1 can replace the structure of the traditional horizontal wind deflector, realize self-oscillating wind up and down at the air outlet 12 when there is no movement of the wind deflector, and when the partition 20 is in the first position 21 , can improve the indoor air mixing efficiency, and can change the indoor steady-state airflow organization form, avoid direct airflow, and achieve a natural and comfortable air supply effect. When the partition 20 is in the third position 22, the directional movement of the airflow can be realized. That is, the steady-state non-oscillating flow, and this can make the airflow flow through the air outlet 12 smaller, and when the amount of airflow is constant, the flow velocity of the airflow at the air outlet 12 can be accelerated, so that long-distance directional air supply can be realized , when the partition 20 is in the second position 26, beam air supply and jet air supply can be realized, and the long-distance jet air supply mode can be realized to meet the long-distance air circulation and anti-direct blowing requirements in the room.

Moreover, a driving part 30 is provided, and the driving part 30 can perform rotation direction, angle control and position reading and writing, thereby controlling the position movement of the internal partition 20 and realizing fast switching of the air supply mode, without using a position switch , for example: micro switch, etc., can identify and control the position of the partition 20, specifically, the driver 30 drives the partition 20 to the first position 21, the first end of the partition 20 is adjacent to the air inlet 11, and the second end Adjacent to the air outlet 12, and the distance between the first end of at least one partition 20 and the central axis of the housing 10 is smaller than the distance between the second end and the central axis of the housing 10, the oscillator 1 is oscillating at this time. When the driving member 30 drives the partition 20 to the second position 26, the distance between the first end of at least one partition 20 and the central axis of the housing 10 is greater than the distance between the second end and the central axis of the housing 10, Moreover, the outlet 133 of the backflow channel 131 is kept in communication with the main channel 130, the oscillator 1 is now a beam outflow, and when the driving member 30 drives the partitions 20 to be in the third position 22, the first end of one of the partitions 20 is adjacent to the outlet. The air outlet 12, and the second end is adjacent to the air inlet 11, the oscillator 1 is directional at this time, so that the driving member 30 can drive the partition 20 to move at the first position 21, the second position 26 and the third position 22, In this way, the mode switching of oscillating air supply, directional air supply and beam air supply can be realized to meet the different needs of users.

For example, the partition 20 at the top cannot rotate counterclockwise, and the partition 20 at the bottom cannot rotate clockwise. The hour hand rotates, which can prevent one of the upper partition 20 and the lower partition 20 from interfering with the other when rotating.

It should be noted that, as shown in Figures 13-15, the positioning position is the position where the partition 20 is positioned by the second stopper 174, at this time, the first end of the partition 20 is adjacent to the air inlet 11, and the second end is adjacent to the air inlet 11.

At this time, the first end of the upper partition 20 is adjacent to the outlet The air outlet 12, and the second end is adjacent to the air inlet 11, and the airflow movement mode is directional upward air supply;

At this time, the first position of the lower partition 20 The first end is adjacent to the air outlet 12, and the second end is adjacent to the air inlet 11, and the airflow movement mode is directed downward air supply;

As shown in FIGS. 20-23 , at least one partition 20 rotates at a certain angle, and at least one partition 20 is positioned only by the drive shaft 31 of the drive member 30 . The distance between the axes is greater than the distance between the second end and the central axis of the casing 10, and the outlet 133 of the return channel 131 is in communication with the main channel 130, and the air flow mode is beam air supply.

Wherein, as shown in FIG. 9, one of the first limiting portion 173 and the second limiting portion 174 is a limiting protrusion, and the other of the first limiting portion 173 and the second limiting portion 174 is a limiting protrusion. The stopper, the limit protrusion cooperates with the stopper of the limit stopper.

In some embodiments, as shown in FIG. 12 , the oscillator 1 of the air conditioner further includes: an elastic member 70, the rotating shaft 27 at the other end of the partition 20 is provided with a mounting groove 270, and the elastic member 70 is disposed in the mounting groove 270, Moreover, the elastic member 70 abuts between the second end plate 171 and the rotating shaft 27 located at the other end of the partition plate 20 . The rotating shaft 27 at the other end of the dividing plate 20 is provided with an installation groove 270, so that the elastic member 70 can be arranged in the installation groove 270, so that the setting of the elastic member 70 is more stable and reliable, and the elastic member 70 has elastic performance, elastic The member 70 abuts between the second end plate 171 and the rotating shaft 27 at the other end of the partition 20, and the elastic member 70 is in a compressed state, so that the elastic member 70 can provide a reverse elastic force to facilitate pushing the partition 20 to the driving direction. One side of the part 30 prevents the separation of the partition plate 20 from the drive shaft 31 of the drive part 30 and ensures the positioning function of the partition plate 20 at the same time. The elastic member 70 can be a spring.

In some embodiments, as shown in Fig. 2, Fig. 13-Fig. 15, there are two partitions 20, the two partitions 20 are arranged symmetrically with respect to the center of the cavity 13, there are two driving parts 30, and the two driving parts 30 are drivingly connected with the two partitions 20 respectively. When there are two partitions 20, preferably, the two partitions 20 are arranged symmetrically relative to the center of the cavity 13, so that the two partitions 20 are conveniently arranged, and when the partitions 20 do not move, the airflow passes through the two partitions. After the plate 20 is deflected, the amplitude difference between the upper and lower air outlets can be made smaller. Of course, according to the actual structure and arrangement of the cavity 13, the two partitions 20 can also be arranged asymmetrically with respect to the center of the cavity 13. There are two driving parts 30, and the two driving parts 30 are drivingly connected to the two partitions 20 respectively, so that the two driving parts 30 can respectively control the two partitions 20, so that the difference between the two partitions 20 can be controlled. turn.

Wherein, as shown in Fig. 2-Fig. 5, the oscillator 1 is obliquely arranged at the front and lower part of the air duct 3, wherein when the partition plate 20 located on the upper side of the central axis of the casing 10 rotates with the rotation axis as the center, and with When the casing 10 is in contact, the airflow passes through the air outlet 12 and then shoots out horizontally. Shot forward and downward.

Moreover, as shown in FIGS. 16-19 , when the partition 20 is in the third position 22, the second end of the partition 20 is disposed adjacent to the casing 10, and the first end and the second end of the partition 20 are positioned at the casing 10. 10 on both sides of the central axis. That is to say, when one of the partitions 20 rotates, optionally, the second end of the partition 20 contacts the housing 10, so that the outlet 133 of the backflow channel 131 on one side of the cavity 13 can be closed, thereby It can prevent the airflow from passing through the backflow channel 131 on one side of the cavity 13 and avoid the interference of the airflow passing through the backflow channel 131 on one side of the cavity 13 , so that the effect of directional movement of the airflow can be better.

It can be understood that when the first end of the upper partition 20 is adjacent to the air outlet 12, and the second end is adjacent to the air inlet 11, the orientation of the air outlet 12 of the oscillator 1 after the upper partition 20 is moved can be oriented obliquely upward. Fluid, because the oscillator 1 is obliquely arranged at the front and lower part of the air duct 3, the airflow at the air outlet 12 of the oscillator 1 can be ejected horizontally, so that when the air conditioner 2 blows out, the wind direction is horizontally forward, preventing the cold wind from directly Blow people. Similarly, when the first end of the lower partition 20 is adjacent to the air outlet 12, and the second end is adjacent to the air inlet 11, an obliquely downward orientation can be produced at the air outlet 12 of the oscillator 1 after the lower partition 20 is moved. Fluid, since the oscillator 1 is obliquely arranged at the front and lower part of the air duct 3, the airflow at the air outlet 12 of the oscillator 1 can be ejected obliquely forward and downward, so that when the air conditioner 2 blows out the air, the air is sent obliquely downward, The hot air is easier to blow to the ground, and the heating effect is better.

In some embodiments, as shown in FIG. 24 , the two partitions 20 are provided with a first arc-shaped guide section 23 , and the first arc-shaped guide section 23 expands toward the air outlet 12 . That is to say, when one of the baffles 20 rotates, the surface of the baffle 20 adjacent to the side of the return passage 131 is an arc surface, so as to ensure that the moved baffle 20 can make use of the fluid "Coanda effect" to make the air flow flow along the arc. Shape-surface movement achieves fluid guidance and reduces resistance loss. In addition, it should be noted that when the partition plate 20 is not moving, after the airflow in the return flow channel 131 returns to the main flow channel 130, part of the airflow in the main flow channel 130 can be deflected. It can play the role of diversion, and another part of the airflow can generate a reverse flow along the direction of the air inlet 11 at the partition 20, thereby producing a vortex effect, and directing the first arc-shaped guide section 23 in the direction toward the air outlet 12 The upper structure is expanded, and the airflow can expand outward along the first arc-shaped guide section 23 , so that the airflow along the first arc-shaped guide section 23 generates a swirl effect high-pressure area.

The following is a detailed description of the flow principle of the airflow when the partition 20 is not moving.

Main airflow deflection effect: As shown in Figure 14 and Figure 15, when the airflow reaches the vicinity of the air outlet 12 along the central axis of the cavity 13 from the air inlet 11, due to the structure of the casing 10 on the upper and lower sides of the air outlet 12, part of the airflow will be along the shell. body 10 structure surface flow, and enter the inlet 132 of the backflow channel 131, due to the inhomogeneity of the flow, the flow rate of the inlet 132 of the backflow channel 131 is different, for example: the flow rate of the airflow through the upper end backflow channel 131 is greater than that through the lower end backflow channel 131 The flow rate of the air flow, and thus the flow rate of the outlet 133 of the return channel 131 is also different, and the main air flow entering from the air inlet 11 will be deflected at the outlet 133 of the return channel 131 by the air flow of different flow rates at the upper and lower ends.

Vortex effect of deflected airflow: As shown in Figure 15, after the deflected airflow approaches the lower partition 20, due to the airflow "attached wall" effect, part of the airflow will move along the lower partition 20, and the main airflow will approach the lower partition 20 At the same time, the air flow in the return channel 131 produces a reverse flow along the direction of the air inlet 11 at the upper partition 20, resulting in a vortex effect, which further pushes the main airflow to one side of the lower partition 20, At this moment, the air outlet 12 produces a downward velocity.

The main airflow is pushed to one side of the partition plate 20 at the lower end, and the flow rate of the airflow at the inlet 132 of the side return channel 131 will be larger than the flow rate of the airflow at the inlet 132 of the return channel 131 at the upper end, thus causing the "main airflow deflection effect". " and "deflection airflow vortex effect" occur on the opposite side, so that upward and downward periodic flow is generated at the air outlet 12, thereby producing the effect of self-oscillation.

In some embodiments, as shown in FIG. 24 , both partitions 20 further include: a first air guide section 24 and a second air guide section 25 , the first air guide section 24 extends away from the air outlet 12 , Moreover, the first air guide section 24 is inclined to the direction of the main flow channel 130, the second air guide section 25 extends away from the air inlet 11, and the second air guide section 25 is inclined to the direction of the main flow channel 130. The outlet 133 of the return channel 131 is defined between the wind section 24 and the housing 10, the inlet 132 of the return channel 131 is defined between the second air guide section 25 and the housing 10, and the first arc guide section 23 is connected to the second air guide section 25. Between the first air guiding section 24 and the second air guiding section 25 .

When the partition 20 is not moving, the first air guide section 24 extends away from the air outlet 12, and the first air guide section 24 is inclined to the direction of the main flow channel 130, so that the airflow can be guaranteed to flow along the direction after entering the cavity 13. The first air guide section 24 is deflected, the second air guide section 25 extends away from the air inlet 11, and the second air guide section 25 is inclined to the direction of the main flow channel 130, so that the air flow can be more conveniently along the second air guide section. The air section 25 is guided to the air outlet 12 and thus led out from the air outlet 12 . The outlet 133 of the return channel 131 is defined between the first air guide section 24 and the housing 10, and the inlet 132 of the return channel 131 is defined between the second air guide section 25 and the housing 10, and part of the air flow can flow from the second air guide section 25 to the housing 10. Between the segment 25 and the casing 10 , enter the return flow channel 131 , and then return to the main flow channel 130 from between the first air guide segment 24 and the casing 10 . The first arc guide section 23 is connected between the first guide section 24 and the second guide section 25, and the first arc guide section 23 is not tangent to the first guide section 24, that is, the air flow along the first guide section 24 After the first arc-shaped guide section 24 moves, it can expand outward along the first arc-shaped guide section 23, so that the airflow can generate a swirl effect high-pressure area along the first arc-shaped guide section 23, and push the main airflow to the opposite side partition 20 , causing the main airflow to bend and turn.

It should be noted that after one of the baffles 20 moves, the end of the second air guide section 25 of the baffle 20 on one side in the cavity 13 is connected to the first air guide section 24 of the baffle 20 on the other side. The distance between the ends is D1, between the end of the first air guiding section 24 of the partition 20 on one side and the end of the second air guiding section 25 of the partition 20 on the other side in the cavity 13 The distance between them is D2, and the relationship between D1 and D2 is: D1>D2. Set in this way, after one of the dividing plates 20 moves, the main channel 130 can form a contracted shape, so that the air can flow into the main channel 130 smoothly after passing through the air inlet 11, and flow along the curved surface. In addition, the narrowest part of the main channel 130 The size can be equivalent to the size of the air inlet 11 of the cavity 13, which can reduce the resistance loss.

In addition, in the longitudinal section of the oscillator 1, the included angle between the first air guiding section 24 and the central axis of the cavity 13 is α, and the included angles between the second air guiding section 25 and the central axis of the cavity 13 are β, α and β The range of values is: 0°<α<90°, 0°≤β<90°. The range of the included angle between the first air guide section 24 and the central axis of the cavity 13 is: 0°<α<90°, that is to say, the first air guide section 24 needs to be inclined in the direction of the main flow channel 130, so as to ensure the air flow After entering the cavity 13, it deflects along the first air guide section 24, and the angle range between the second air guide section 25 and the central axis of the cavity 13 is: 0°≤β<90°, and the second air guide section 25 can flow toward the main flow. The direction of the passage 130 is arranged obliquely, and can also be arranged parallel to the central axis of the cavity 13 , so that the airflow can be guided to the air outlet 12 when passing through the second air guiding section 25 .

In some embodiments, the casing 10 includes: a tapered section, the tapered section is disposed at the air inlet 11 , and the cross-sectional area of the tapered section gradually decreases toward the air outlet 12 . A tapered section is provided at the air inlet 11, and the cross-sectional area of the tapered section gradually decreases toward the air outlet 12, so that the air flow enters the cavity 13 through the air inlet 11 and produces a jet effect to prevent the air flow from diverging.

Wherein, the end of the tapered section away from the air inlet 11 is the first end, and the end of the first air guide section 24 adjacent to the air inlet 11 is the second end. In the longitudinal section of the oscillator 1, the size of the first end is L1, the distance between the second ends of the two partitions 20 is L2, and the relationship between L1 and L2 is: L1<L2. That is to say, the size of the first end is smaller than the distance between the second ends of the two partitions 20. When the partitions 20 are not moving, after the airflow enters the cavity 13, it can flow to the first air guide section 24. The direction is deflected, so as to ensure the deflection space after the airflow enters the main channel 130 .

In some embodiments, the end connecting the first arc guide section 23 to the first air guide section 24 is the third end, and the distance between the third ends of the two partitions 20 is L3, where L3>L2 . The distance between the third ends of the two partitions 20 is greater than the distance between the second ends of the two partitions 20, so that when the airflow flows along the main flow channel 130, the deflection space of the airflow can be large enough .

In some embodiments, the air channel member 3 includes: an upper air channel wall and a lower air channel wall, the upper air channel wall and the lower air channel wall define the air channel outlet 60, the upper air channel wall and the lower side The cross-sectional area of the wall of the air duct gradually decreases toward the outlet 60 of the air duct. The upper side air channel wall and the lower side air channel wall define the air channel outlet 60, so that the air flow in the air channel member 3 can pass between the upper side air channel wall and the lower side air channel wall, and pass through the air channel outlet 60. into the vibrator 1, and the cross-sectional area of the upper side air channel wall and the lower side air channel wall all gradually decreases towards the direction of the air channel outlet 60, so that the airflow enters the air channel through the air channel outlet 60 and the air inlet 11. A jet effect will be produced behind the cavity 13, thereby preventing the airflow from diverging.

Wherein, the end of the upper air channel wall away from the air channel outlet 60 is the fourth end, the end of the lower air channel wall far away from the air channel outlet 60 is the fifth end, and the involute of the fan 50 is located at the fifth end. The connecting line between the front end, the fourth end and the fifth end is perpendicular to the upper air duct wall. The involute of the fan 50 is located at the front end of the fifth end, which can reduce the influence of the fan 50 on the airflow between the upper air duct wall and the lower air duct wall, while the fourth end and the fifth end The connection line of is perpendicular to the upper air duct wall, that is to say, the fifth end is the arc tangent point of the socket tongue of the air duct part 3, which is convenient for setting and can make the air flow better enter the upper air duct wall and between the lower side air duct wall.

In addition, the end connecting the upper air duct wall to the oscillator 1 is the sixth end, and the end connecting the lower air duct wall to the oscillator 1 is the fourth end. In the longitudinal section of the air duct member 3, the fourth The distance between the end and the fifth end is L4, the distance between the sixth end and the fourth end is L5, and the relationship between L4 and L5 is: L4>L5. That is to say, the distance between the fourth end and the fifth end is larger than the distance between the sixth end and the fourth end, so that the horizontal distance between the upper air duct wall and the lower air duct wall will be realized. The cross-sectional area gradually decreases toward the air duct outlet 60, so that the air flow enters the cavity 13 through the air duct outlet 60 and the air inlet 11, and a jet effect will be generated to prevent the air flow from diverging.

In addition, as shown in FIGS. 13-23 , the housing 10 includes: a constricted section 14 disposed at the air outlet 12 , and the cross-sectional area of the constricted section 14 gradually decreases toward the air outlet 12 . The cross-sectional area of the constricted section 14 gradually decreases toward the air outlet 12, and the end of the constricted section 14 away from the air outlet 12 can be configured as a circular arc, so that the airflow can flow out smoothly along different angles during self-oscillation, reducing The resistance at the air outlet 12.

In addition, as shown in FIGS. 20-23 , after at least one partition 20 rotates around the rotation axis, the distance between the ends of the first air guide sections 24 of the two partitions 20 away from the air outlet 12 is a, The distance between the ends of the second air guide section 25 of the two partitions 20 away from the air inlet 11 is b, and the distance between the ends of the contraction section 14 away from the air outlet 12 is c, wherein, between a, b and c The relationship is: a>b, and b≥c, or a>b, and b<c.

Understandably, when a>b, and b≥c, as shown in Figure 20 and Figure 21, the distance between the first ends of the two separators 20 is greater than the distance between the second ends, so the main channel 130 The overall shape is contracted to ensure that the airflow converges toward the central axis of the casing 10 along the edge, so that the airflow can flow out through the air outlet 12 after passing through the beam.

When a>b, and b<c, as shown in Fig. 22 and Fig. 23, the distance between the second ends of the two partitions 20 is relatively small. The distance between the second ends of the two partitions 20 is reduced to increase the flow velocity. At this time, the beam becomes a jet, and the oscillator 1 as a whole becomes a jet channel. At this time, most of the air flows through the partitions 20 Flow out along the central axis of the housing 10, a small part of the fluid flows out along the partition 20 in the reverse direction through the partition 20 and the inner walls of the cavities 13 on both sides due to the pressure, and this part of the fluid is further mixed with the airflow of the main channel 130 to reduce the jet flow The divergence effect increases the jet distance.

In some embodiments, as shown in FIGS. 13-23 , the casing 10 further includes: a second arc-shaped flow guide section 15, the second arc-shaped flow guide section 15 is connected to the contraction section 14, and the second arc-shaped flow guide section 15 The cross-sectional area of the flow section 15 gradually decreases toward the air outlet 12 . The second arc-shaped guide section 15 is connected to the second contraction section 14. When one of the partitions 20 rotates, part of the air flow will be affected by the second arc-shaped guide section 15 to generate a rotating vortex. The outer edge of the vortex The fluid has a certain moment of inertia, and when mixed with the air flow of the main flow channel, the direction of the air flow in the main flow channel can be further changed. When the partition plate 20 does not rotate, part of the air flow can be The surface flows and guides the flow to the inlet 132 of the return channel 131, thereby entering the return channel 131, and the cross-sectional area of the second arc-shaped guide section 15 gradually decreases toward the air outlet 12, so that part of the flow can be guaranteed. When the air flow encounters the second arc guide section 15 , it can flow back to the inlet 132 of the corresponding return channel 131 . It should be noted that, under the premise of ensuring the flow guiding effect of the second arc-shaped flow guiding section 15 , the structure of the second arc-shaped flow guiding section 15 may not be arc-shaped.

In addition, after at least one partition 20 rotates around the rotation axis, the extension line of the second air guide section 25 of the partition 20 on the inner side of the cavity 13 and the second arc on the inner side of the cavity 13 The diversion sections 15 do not intersect. It can be understood that when the baffle 20 is in the second position 26, and the extension line of the second air guide section 25 of the baffle 20 on the side inside the cavity 13 is in line with the second arc guide section 25 on the side inside the cavity 13 When the flow sections 15 do not intersect, since the airflow flows out as a beam, the airflow in the main flow channel 130 can avoid contact with the second arc-shaped guide section 15 after passing through the second air guide section 25, thereby preventing the airflow from passing through the second air guide section 25. The two-arc guide section 15 enters the inlet 132 of the return channel 131 to affect the beam effect of the airflow. It should be noted that the extension line of the second air guiding section 25 of the partition 20 located on the inner side of the cavity 13 may also intersect the second arc-shaped air guiding section 15 located on the inner side of the cavity 13. , which can also prevent the airflow from entering the inlet 132 of the return channel 131 through the second arc-shaped guide section 15 to a certain extent, of course, it is preferable that the two do not intersect.

Besides, the oscillator 1 also includes: a dustproof door, which is movably arranged at the air outlet 12 . A dust-proof door can be provided at the air outlet 12, and the dust-proof door can rotate or slide at the air outlet 12, so that the opening and closing of the air outlet 12 can be realized, and dust enters the air conditioner 2 through the air outlet 12 when the air conditioner 2 is turned off. Inside the cavity 13.
