In addition, the meaning of "and/or" appearing throughout is to include three juxtapositions, exemplified by "A and/or B" including either scheme A, or scheme B, or a scheme in which both A and B are satisfied.

Referring to fig. 1, the present invention provides a wall-mounted air conditioner indoor unit 300, which includes a housing 310 and a vortex ring generating device 100, wherein the housing 310 has a main air inlet, a main air outlet 311, a heat exchange air duct communicating the main air inlet and the main air outlet 311, and a vortex ring air outlet 312, the vortex ring air outlet 312 and the main air outlet 311 are disposed at an interval, the vortex ring generating device 100 is disposed in the housing 310, and the vortex ring generating device 100 is used for periodically driving an air flow to blow out through the vortex ring air outlet 312.

In this embodiment, the heat exchange duct means that the airflow entering from the main air inlet can exchange heat in the duct and then be blown out from the main air outlet 311. The cross section of the heat exchange air duct can be in a circular, oval or arc structure, and the extension shape of the heat exchange air duct can be in a straight cylinder shape or a bending shape. The heat exchange air duct can be directly formed by the enclosure of the machine shell or formed by the enclosure of an inner shell in the machine shell. A heat exchanger can be arranged in the heat exchange air duct, and the heat exchanger exchanges heat for air flow flowing into the heat exchange air duct to form cold air or hot air to be blown out. The heat exchanger can be a finned tube evaporator, a plate evaporator, or the like, and the air flow after heat exchange of the heat exchanger is blown out through the main air supply outlet 311, so that the heating or refrigerating purpose is achieved. Because the common air supply mode directly blows cold air or hot air to the human body, the human body feels uncomfortable,

in this embodiment, the vortex ring generating device 100 drives the air current to periodically blow out through the vortex ring air supply outlet 312, a vortex ring is generated, the mode of vortex ring air supply can realize orientation, fixed point and remote air supply, and the vortex ring exchanges heat with the ambient air in the transmission process, the temperature difference between the temperature of the vortex ring and the ambient air is not large, so that the vortex ring can not generate obvious supercooling or overheating feeling when blowing on the human body, the comfort is improved, meanwhile, the indoor air circulation is improved, and the comfort of indoor personnel is improved.

In an embodiment, the wall-mounted air conditioner indoor unit 300 includes a cross flow wind wheel, and the cross flow wind wheel is disposed in the heat exchange air duct and is used for driving indoor air to flow in from the main air inlet and flow out from the main air outlet 311 after passing through the heat exchange air duct, so as to realize heat exchange of the indoor air.

In one embodiment, the wall-mounted air conditioner indoor unit further includes a wind deflector movably disposed on the casing for opening and closing the main air outlet, and the wind deflector is provided with a plurality of wind dissipating holes. In this embodiment, when the air is discharged normally, the air deflector opens the main air outlet 311, and the air flow after heat exchange is directly blown out from the main air outlet 311, and in the no-wind-sensation mode, the air deflector closes the main air outlet 311, so that the air flow can be blown out through the air dispersing holes on the air deflector, thereby achieving the effect of softening the air supply without generating obvious air flow. The user feels comfortable, but because the air circulation is not sufficient, the indoor personnel can feel stuffy. At this time, the vortex ring is generated by the vortex ring generating device 100, so that directional, fixed-point and remote air supply is realized, the mobility of indoor air is enhanced, and the user experience is enhanced.

In one embodiment, the main air inlet is arranged at the upper end of the shell, the main air supply outlet is arranged at the lower end of the shell, and the length direction of the main air supply outlet extends along the transverse direction. In this embodiment, the room air independently air intake gets into the heat transfer wind channel from the shell upper end, blows off from the main supply-air outlet of shell lower extreme after the heat transfer, and the length direction of main supply-air outlet mouth is along horizontal extension to realize the wide-range air supply on a wider range, the air supply is effectual.

The arrangement of the scroll ring supply air ports 312 is various. Because a common air conditioner indoor unit is long, the main air supply outlet 311 extends along the length direction of the machine body, and the vortex ring air supply outlet 312 is arranged at least one end of the main air supply outlet 311 in the length direction, which is beneficial to the arrangement of the internal components of the machine shell and is more beautiful. In the present embodiment, referring to fig. 1, two vortex ring air outlets 312 are provided and are respectively disposed at two lateral sides of the main air outlet 311. The vortex ring air outlet 312 may be blown by an air flow driven by one set of the vortex ring generating apparatus 100, or may be blown by air flows driven by two sets of the vortex ring generating apparatuses 100. The two vortex ring air outlets are arranged, so that the vortex ring air supply in a wider range is facilitated, and the indoor air flow is more uniform.

In addition to the above embodiment, referring to fig. 3 and 8, the vortex ring generating device 100 includes a housing 10 and a vortex ring generating portion 20. The casing 10 has a first port 111, a second port 112 and an air outlet cavity 11, the air outlet cavity 11 communicates the first port 111 and the second port 112, and an air passing area of the second port 112 is smaller than an air passing area of the first port 111. The vortex ring generating part 20 is disposed on a side of the first port 111 away from the second port 112, and the vortex ring generating part 20 can periodically drive the airflow to flow through the air outlet cavity 11 and be blown out from the second port 112.

In this embodiment, the vortex ring generating portion 20 generates a disturbance in the air supply direction to the air in the air outlet cavity 11, and periodically drives the air flow to blow out through the air outlet cavity 11, because the air passing area of the second port 112 of the air outlet cavity 11 is smaller than the air passing area of the first port 111, when the air flow is blown out through the second port 112, a flow field distribution with a slow peripheral flow rate and a large intermediate flow rate is formed, so as to generate a vortex ring air flow, thereby realizing remote air supply and wide area air supply, disturbing indoor air, and enhancing the indoor air circulation effect.

There are various ways for the vortex ring generator 20 to periodically drive the airflow to be blown out through the outlet cavity 11. The first port 111 may be communicated with a heat exchange air duct of the indoor unit of the air conditioner, and the heat exchange fan may continuously blow the air flow to the air outlet cavity 11. The first port 111 may not be communicated with the heat exchange air duct, and an air flow driving device may be disposed to drive the indoor air flow to the first port 111.

For example, in an embodiment, the vortex ring generating portion 20 may be a switch door structure, the switch door is disposed at the first port 111 of the air outlet cavity 11 to block the airflow from flowing into the air outlet cavity 11, and the driving device is connected to the switch door to drive the switch door to open or close. The periodic driving of the air flow is achieved by controlling the driving switch door to reciprocate periodically or to repeatedly open or close the first port 111. In this embodiment, it should be noted that when the switch door is closed, that is, when the first port 111 is closed, the switch door may be completely closed, or may be partially closed, for example, 2/3, 4/5, 5/6, 9/10 and the like that close the first port 111. When the vortex ring generating portion 20 operates, since the first port 111 is continuously supplied with air, a certain volume of air is accumulated outside the first port 111. When the vortex ring generating part 20 opens the first port 111, a driving force is generated to drive the airflow to flow to the second port 112 due to the pressure difference, and the second port 112 can blow out the vortex ring airflow because the over-wind area of the second port 112 is smaller than that of the first port 111. The opening and closing door can be of a shutter structure, a door plate structure, a fan structure and the like. The driving device can comprise a control panel and a driving part, the driving part can be a hydraulic device, an air pressure device or a motor 221 driving device, and the driving device can drive the opening and closing door to rotate, stretch and the like so as to drive the opening and closing door to open and close periodically. The control board controls the driving member to drive the opening and closing door to repeatedly open or close the first port 111. The structure of opening and closing the door is added through the driving device, the structure is simple and stable, and the control is convenient, so that the smooth generation of vortex ring airflow is more facilitated.

In one embodiment, the door includes a plurality of blades, the vortex ring generating portion 20 further includes a transmission member, the transmission member is connected to the plurality of blades, and the driving device is connected to the transmission member to drive the plurality of blades to open or close. In this embodiment, the blade structure makes the switching mode of switch door simple more reliable, and easily realizes. In one embodiment, the driving device is an electromagnet, the transmission member includes a gear connected to a blade rotating shaft, a rack 213 connected to the electromagnet, and a transmission rod connected to the blade rotating shafts in a transmission manner, and the rack 213 is driven by the pulse of the electromagnet to drive the gear to rotate so as to drive the blades to open or close. Pulse signals are given by the electromagnet to drive the rack 213 to reciprocate, so as to drive the gear to rotate and drive the blades to be rapidly opened and closed within a certain angle. In another embodiment, the driving device is a motor 221, the transmission member includes a gear connected to the shaft of the motor 221, a pinion engaged with the gear and fixedly connected to a blade rotating shaft, and a transmission rod connected to the blade rotating shafts in a transmission manner, the motor 221 drives the gear to rotate the pinion to drive a blade to rotate around the rotating shaft, so as to link the blades to turn.

In the present embodiment, please refer to fig. 3 to 8, the vortex ring generating portion 20 includes a generating cavity 210 and a driving mechanism, the generating cavity 210 is connected to the first port 111 of the housing 10, and the driving mechanism is configured to periodically compress the generating cavity 210, so that the airflow flows into the air outlet cavity 11 from the generating cavity 210 and is blown out through the second port 112. Thus, the vortex ring generator 20 periodically drives the airflow into the air outlet cavity 11, and pushes the airflow to be blown out from the second port 112, so that the airflow has a certain flow velocity. Due to the pressure difference between the middle area and the peripheral area of the second port 112, the airflow at the side of the second port 112 is supplemented to the edge of the second port 112, so that the vortex ring airflow can be blown out of the second port 112, the diameter of the vortex ring airflow is gradually increased, and further, long-distance and wide-area air supply is realized.

The generation volume 210 may be disposed within a compression member, which may be a piston structure, a membrane structure, or the like. In one embodiment, a piston is disposed in the compression element, the generation cavity 210 is disposed at one side of the piston, and the driving mechanism includes a connecting rod, one end of which is connected to the piston for driving the piston to reciprocate in the compression direction. When the piston moves towards the generation cavity 210, the gas can be pushed to form vortex ring airflow via the air outlet cavity 11 to be blown out. In another embodiment, when the compression member is a membrane structure, the membrane structure is a flexible material or an elastic material. And the thin film structure shell 10 is fixedly connected, and by pushing and pulling the thin film structure, the airflow can be periodically extruded to form vortex ring airflow through the air outlet cavity 11 to be blown out. The driving device may include a driving member and a transmission member, and the driving member may be a motor 221 driving device, a hydraulic driving device, a pneumatic driving device, an electromagnet driving device, or the like. The transmission member may be a screw transmission member, a worm and gear transmission member, a rack and pinion 213 transmission member, a connecting rod transmission member, etc., and it is only necessary to enable the driving member to drive the transmission member to move so as to drive the compression member to extrude out of the volume of the generation accommodating cavity 210, which is not specifically limited herein. Further, there are various ways to drive the piston to reciprocate, and in an embodiment, the driving device further includes an electromagnetic driving element, specifically, the electromagnetic driving element may include a first electromagnet and a second electromagnet, and the driving element is driven to reciprocate by controlling the periodic electrical connection and disconnection of the electromagnets, so as to periodically compress the generation cavity 210.

In this embodiment, please refer to fig. 3 and 8, the vortex ring generating portion 20 includes a flexible telescopic portion 211, the flexible telescopic portion 211 is hollow to form a generating cavity 210, the generating cavity 210 is not communicated with the heat exchange air duct, one end of the flexible telescopic portion 211 is provided with an opening 214, the opening 214 is abutted to the first port 111 of the housing 10, the other end of the flexible telescopic portion 211 is provided with a pushing plate 212, the pushing plate 212 has a stretching position far away from the first port 111 and a compressing position close to the first port 111, and the driving mechanism drives the pushing plate 212 to reciprocate between the stretching position and the compressing position to periodically compress the flexible telescopic portion 211. In this embodiment, when the push plate 212 is driven to move from the compressed position to the extended position, room air enters the generation volume 210 via the first port 111 and an airflow is collected within the generation volume 210. When the pushing plate 212 is driven to move from the stretching position to the compressing position, the flexible expansion part 211 is squeezed, and air is extruded from the generation cavity 210, passes through the air outlet cavity 11, and is blown out from the second port 112 without an additional fan assembly.

The drive mechanism may have a variety of configurations, as long as it is capable of expanding and contracting the volume of the generation volume 210, and may be, for example, a piston. In this embodiment, referring to fig. 2 and fig. 6, the driving mechanism includes a driving part and an elastic member 220, the driving part is drivingly connected to the pushing plate 212 to periodically drive the pushing plate 212 to move away from the first port 111 to the extended position, and the elastic member 220 is connected to the pushing plate 212 to provide a restoring force, so that the pushing plate 212 returns from the extended position to the compressed position under the restoring force. In this embodiment, the driving part drives the pushing plate 212 to move away from the first port 111 to expand the volume of the generation cavity 210 for pressure accumulation, and the elastic member 220 enables the pushing plate 212 to return to the compression position under the action of elastic force, so as to realize rapid rebound of the pushing plate 212, and under the influence similar to the slingshot effect, the generation cavity 210 is rapidly squeezed, and the airflow is driven to blow out through the second port 112. Therefore, compared with a common driving mode, the air flow speed is increased, so that an obvious vortex ring is generated, and air supply at a longer distance is realized.

The direction of the air flow from the scroll ring air supply outlet 312 may be varied, such as downward air supply or forward air supply. In the present embodiment, referring to fig. 3 and 8, the first port 111 is disposed at the upper end of the casing 10, the second port 112 is disposed at the lower end of the casing 10 and faces obliquely downward, and the vortex ring generator 20 is disposed above the casing 10. It will be understood by those skilled in the art that in other embodiments, the layout of the vortex ring generating apparatus 100 and the direction of the vortex ring air supply may be adapted as necessary.

In general, the vortex ring generating unit 20 provided in the air conditioner generates a vortex ring by blowing air in the front-rear direction. However, the wall-mounted air conditioning indoor unit 300 has a small thickness in the front-rear direction, and if the air is blown in the front-rear direction, for example, if the push plate 212 reciprocates in the front-rear direction, the air flow generated due to insufficient displacement may not be large enough, and the air flow may not be rectified at a sufficient distance, so that a stable vortex ring may not be generated. In the present embodiment, the vortex ring generating portion 20 and the housing 10 are arranged in the vertical direction, and the air flow is driven from the top to the bottom and blown out obliquely downward through the air outlet cavity 11. Since the wall-mounted indoor air conditioner has a small thickness and a large height, the above arrangement can reduce the thickness of the vortex ring generating device 100 in the front-rear direction, which is advantageous for installation in the wall-mounted indoor air conditioner, and on the other hand, the air flow blown out from the obliquely lower side can disturb the indoor air more effectively, reducing the feeling of stuffiness of the indoor personnel. And the push-pull plate has enough displacement distance in the vertical direction in the machine shell and can move downwards to a compression position more quickly under the action of gravity, so that airflow with enough flow velocity can be generated, meanwhile, the airflow flows in the air passing cavity along the vertical direction, and compared with a forward-backward flow mode, the flow rectification distance is longer, so that a stable vortex ring is favorably generated.

On the basis of the above embodiment, when the airflow is blown out from top to bottom in the air outlet cavity 11, the flow velocity in the up-down direction is the largest, and the second port 112 is arranged facing obliquely downward, so that the vortex ring is also blown out facing obliquely downward, the original direction of the airflow is changed, and the wind velocity on one side is faster and the wind velocity on the other side is slower in the air outlet direction, which affects the vortex ring forming effect. In order to collect the airflow, it is preferable that the inner wall of the outlet cavity 11 extends in the up-down direction and is at least partially inclined toward the second port 112. So, the inner wall of slope produces the water conservancy diversion effect to the air current of flowing through air-out cavity 11, makes the direction that the air current flows and the direction of vortex ring air supply more close, has alleviateed the unfavorable effect that changes the air current direction, is favorable to the shaping of vortex ring.

Optionally, referring to fig. 3 and 8, the pushing plate 212 is disposed above the housing 10, the flexible expansion portion 211 is disposed between the pushing plate 212 and the housing 10, a rack 213 extending up and down is disposed on the pushing plate 212, the driving component includes a motor 221 and an incomplete gear 222, the motor 221 is drivingly connected to the incomplete gear 222, and the incomplete gear 222 is engaged with the rack 213 to drive the pushing plate 212 to move up periodically. That is, when the incomplete gear 222 is engaged with the rack 213, the pushing plate 212 is driven to slide upwards, and at the same time, the elastic member 220 between the pushing plate 212 and the housing 10 is pulled, after the rack 213 moves to the stretching position, because the incomplete gear 222 lacks teeth, the rack 213 is disengaged, the pulled elastic member 220 drives the pushing plate 212 to rebound rapidly and return to the compression position, the volume in the cavity 210 changes rapidly, the driving airflow is rapidly blown out through the air outlet cavity 11, and a vortex ring is generated. The driving component may have various structures as long as the pushing plate 212 can be periodically driven to move upwards and the limit on the pushing plate 212 is released. In the embodiment, the incomplete gear 222 is matched with the rack 213 to realize the periodic stretching of the flexible expansion part 211, so that the vortex ring can be regularly generated, the driving part is easy to control, the driving part does not need to be frequently operated to open and close, and the misoperation is not easy to occur.

In order to make the pushing plate 212 move up and down more stably, referring to fig. 2, preferably, the vortex ring generating device 100 further includes a guiding column 230, the guiding column 230 is installed on the housing 10 and extends upward, and the pushing plate 212 is slidably connected to a side wall of the guiding column 230. As shown in fig. 4, the pushing plate 212 is provided with a concave portion matching with the guiding post 230, so as to limit the pushing plate 212.

In another embodiment, referring to fig. 6, the vortex ring generator 100 further includes a guide post 230, the guide post 230 extends upward from the upper side of the housing 10, the pushing plate 212 is provided with a guide hole 215, and the pushing plate 212 is slidably sleeved on the guide post 230 through the guide hole 215. Thus, the pushing plate 212 is limited horizontally and vertically, and the pushing plate 212 can move up and down stably. Preferably, a rib is provided between the guide post 230 and the guide hole 215. Thereby reducing the contact area between the guide post 230 and the inner wall of the guide hole 215, reducing the friction force, and enabling the push plate 212 to slide more smoothly.

Further, referring to fig. 6 to 8, a cover plate 231 is disposed at an upper end of the guide post 230, the elastic element 220 includes a tension spring sleeved on the guide post 230, an upper end of the tension spring abuts against a lower side of the cover plate 231, and a lower end of the tension spring abuts against an upper side of the pushing plate 212.
