wherein the collecting member 123 is rotatable with respect to the housing 110 and has a rotation locus, and a center line of the rotation locus is not coincident with a center line of the blowing port 1231.
In the embodiment of the present invention, the indoor unit 100 of the air conditioner has the first air outlet 114, and the first air outlet 114 can realize vortex ring air supply. Specifically, the housing 110 includes a front panel 111 and two side plates 112 connecting both sides of the front panel 111, and the first outlet port 114 is provided in the front panel 111. It is understood that, in order to realize various types of air supply, the indoor unit 100 may further include a second outlet 122b (a conventional outlet), and the second outlet 122b is disposed on at least one of the side plates 112. An air door is installed at the second air outlet 122b, and the air door is used for opening or closing the second air outlet 122 b.
Referring to fig. 1 and 2, in an embodiment, the first air inlet 113 is disposed at a lower end of the outer shell 110, and the first air outlet 114 and the second air outlet 122b are both disposed at an upper end of the outer shell 110. An air duct communicating the first air inlet 113 with the first air outlet 114 and the second air outlet 122b is formed in the housing 110, and a fan assembly 160 and a heat exchanger 150 are arranged in the air duct, so that under the driving of the fan assembly 160, air enters the air duct from the first air inlet 113, is subjected to heat exchange by the heat exchanger 150, and then is blown out from the first air outlet 114 and/or the second air outlet 122b, so that the indoor temperature distribution is relatively uniform.
In the embodiment of the present invention, the vortex ring generator 120 can periodically blow out a vortex ring airflow, and the vortex ring generator 120 may be installed inside or outside the housing 110, and is not particularly limited herein. Specifically, the scroll ring generating device 120 is formed with a plurality of scroll ring air ducts, for example, the scroll ring air duct may be formed by the cavity of the air duct 122, or may be formed by the cavity of the air duct 122 and other components (for example, the scroll ring generating portion 126). The vortex ring generating portion 126 is installed in the vortex ring air duct to periodically drive the air flow to be blown out through the collecting member 123, or to periodically pass through the air flow to be blown out through the collecting member 123.
There are various structures related to the vortex ring generating portion 126, for example, in an embodiment, the vortex ring generating portion 126 includes an opening and closing door and a second driving device, the opening and closing door is installed in the vortex ring duct to block the airflow in the vortex ring duct from flowing to the collecting member 123; the second driving device is connected to the opening and closing door to periodically drive the opening and closing door to open or close, so that the air flow can be periodically blown out through the collecting member 123. The opening and closing door can realize the function of quickly opening/closing the door under the driving action of the second driving device, so that the air coming out of the air supply outlet 1231 is in a pulse type, and necessary conditions are provided for the generation of the vortex ring. When the opening and closing door is closed, the wind generated by the fan assembly 160 generates a high voltage before the opening and closing door; when the switch door is opened, high-pressure air flow before the switch door rapidly passes through the switch door, and a vortex ring is formed at the air outlet under the acceleration action of the flow collecting piece 123. Here, it should be noted that the closing may be a complete closing or a partial closing, for example, closing 2/3, 4/5, 5/6, 9/10, and the like.
The opening and closing door can be a shutter structure, a door plate structure, a fan structure and the like, and the opening and closing door structure is opened or closed periodically, so that air with certain pressure accumulated on one side of the opening and closing door can quickly flow to the air supply outlet 1231 and then forms a vortex ring to be blown out. In one embodiment, the opening/closing door includes a plurality of blades, the vortex ring generating portion 126 further includes a transmission member, the transmission member is connected to the plurality of blades, and the second driving device is connected to the transmission member to drive the plurality of blades to open or close. In the embodiment, the blade structure enables the opening and closing mode of the opening and closing door to be simpler and more reliable, and is easy to realize. In one embodiment, the driving device is an electromagnet, the transmission part comprises a gear connected with a blade rotating shaft, a rack connected with the electromagnet, and a transmission rod in transmission connection with the blade rotating shafts, and the rack is driven by the pulse of the electromagnet to drive the gear to rotate so as to drive the blades to be opened or closed. Pulse signals are given through the electromagnet to drive the rack to do reciprocating motion, and then the gear is driven to rotate so as to drive the blades to be rapidly opened and closed within a certain angle.
In another embodiment, the vortex ring generator 126 may be a compression structure, an air compressor, or the like, so as to periodically drive the airflow to be blown out through the collecting member 123. The vortex ring generator 126 periodically disturbs the airflow in the vortex ring air duct, so that the airflow can be pushed to be blown out from the air blowing port 1231 and has a certain flow velocity. Due to the pressure difference between the middle area and the peripheral area of the air supply opening 1231, the airflow at the side edge of the air supply opening 1231 is supplemented to the edge of the air supply opening 1231, so that the vortex ring airflow can be blown out at the air supply opening 1231, the diameter of the vortex ring airflow is gradually increased, and then remote and wide-area air supply is realized. Specifically, the scroll ring generator 126 includes a driving member (not shown) and a compression member (not shown), the compression member is installed in the scroll ring duct, and the driving member is connected to the compression member to periodically drive the compression member to compress the gas on the side of the scroll ring duct close to the air outlet 1231 and to blow the gas out through the air outlet 1231.
In this embodiment, the compression member may be a piston structure, a membrane structure, or the like. When the compression piece is in a piston structure, the piston and the inner wall surface of the vortex ring air channel are sealed and can move relatively. When the driving piston of the driving piece moves in the vortex ring air duct, the gas on one side, close to the air supply opening 1231, of the vortex ring air duct can be compressed, and then the gas is pushed to form vortex ring airflow from the air supply opening 1231 to be blown out. There are various piston structures, for example, in one embodiment, the piston structure includes a pushing plate and a pushing rod connected to the pushing plate, and the pushing plate is movably connected to the inner wall surface of the vortex ring air duct. The driving piece drives the pushing rod to drive the pushing plate to move in the vortex ring air channel. When the compression element is of a film structure, the film structure is made of a flexible material or an elastic material and is fixedly connected with the inner wall surface of the vortex ring air duct, and the gas on one side, close to the air supply port 1231, of the vortex ring air duct can be periodically extruded by pushing and pulling the film structure, so that the air flow is driven to form vortex ring air flow from the air supply port 1231 and blown out.
In the embodiment of the present invention, the collecting member 123 is installed at the second air outlet 122b, the collecting member 123 and the air duct 122 may be integrally formed, and of course, the collecting member 123 and the air duct 122 may also be separately formed. That is, the air duct 122 may rotate together with the collecting member 123, or may be fixed to the housing 110 without rotating, which will be described in detail below. The structure of the collecting member 123 may be various, for example, in an embodiment, the collecting member 123 is cylindrical, and the collecting member 123 is tapered along the direction of the wind pipe 122 toward the wind feeding opening 1231, so that the wind passing area of the wind feeding opening 1231 is smaller than the wind passing area of the first wind outlet 114. In another embodiment, the current collecting member 123 may also have a plate shape, and the air blowing port 1231 is opened on the current collecting plate.
It should be noted that the collecting member 123 is rotatable relative to the housing 110 and has a rotation track, and a center line of the rotation track is not coincident with a center line of the air blowing opening 1231, so that when the collecting member 123 is driven to rotate, a position of the air blowing opening 1231 can be continuously changed, and thus an air blowing direction can be changed. Here, it should be explained that the rotation trajectory may be a circular trajectory, an elliptical trajectory, a spiral trajectory, or a trajectory of other shape; the center line of the air blowing port 1231 is a straight line passing through the center of the air blowing port 1231 and perpendicular to the air blowing surface. The fact that the center line of the rotation trajectory does not coincide with the center line of the air blowing port 1231 means that the center line of the rotation trajectory is offset from the center line of the air blowing port 1231, that is, the center line of the rotation trajectory is different from the center line of the air blowing port 1231. In the embodiment of the present invention, the collecting member 123 communicates with the indoor space through the first air outlet 114, and the collecting member 123 can rotate relative to the housing 110 to change the air blowing direction of the air blowing outlet 1231, so that the air blowing area of the first air outlet 114 needs to be larger than the air blowing area of the air blowing outlet 1231. The shape of the air blowing port 1231 is not particularly limited, and the air blowing port 1231 may have a triangular shape, a circular shape, an elliptical shape, a square shape, or another irregular shape, for example.
The air-conditioning indoor unit 100 of the present invention includes a vortex ring generating device 120 mounted on the outer casing 110, wherein the vortex ring generating device 120 includes an air duct 122, a flow collecting member 123 and a vortex ring generating portion 126, the air duct 122 has a second air inlet 122a and a second air outlet 122 b; the flow collecting piece 123 is installed at the second air outlet 122b, an air supply outlet 1231 communicated with the air duct 122 is arranged on the flow collecting piece 123, the air passing area of the air supply outlet 1231 is smaller than that of the second air outlet 122b, and the air supply outlet 1231 is communicated with the indoor space through the first air outlet 114; the vortex ring generator 126 is used to periodically drive the airflow to be blown out through the current collector 123, or used to periodically blow the airflow through the current collector 123; wherein the collecting member 123 is rotatable with respect to the housing 110 and has a rotation locus, and a center line of the rotation locus is not coincident with a center line of the blowing port 1231. Therefore, the flow collecting piece 123 is driven to rotate around the rotation track of the flow collecting piece, so that the air supply direction of the air supply opening 1231 can be changed, the air supply direction of the indoor unit 100 of the air conditioner can be changed, the indoor temperature distribution is more uniform, and the use experience of a user is improved.
Referring to fig. 4 and 5, in an embodiment, the air duct 122 is mounted to the housing 110, and the collecting member 123 is rotatably connected to the air duct 122. In this embodiment, the air duct 122 is fixed to the housing 110, and the collecting member 123 is rotatable with respect to the air duct 122. It is understood that in another embodiment, the air duct 122 may rotate with the collecting member 123, specifically, the air duct 122 is rotatably mounted to the housing 110, and the collecting member 123 is connected to the air duct 122.
In order to better drive the collecting member 123 to rotate, the indoor unit 100 of the air conditioner further includes a first driving device 130, and the first driving device 130 is connected to the collecting member 123 to drive the collecting member 123 to rotate.
There are various structures of the first driving device 130, and there is no particular limitation thereto. For example, referring to fig. 5, fig. 6 and fig. 7, in an embodiment, the first driving device 130 includes a first motor 131 and a gear 132 disposed on a motor shaft of the first motor 131, a rack 133 engaged with the gear 132 is disposed on the current collecting member 123, and the rack 133 extends along a circumferential direction of the current collecting member 123. In another embodiment, the first driving device 130 includes a second motor and a first gear 132 disposed on a motor shaft of the second motor, and the current collecting member 123 is provided with a second gear 132 engaged with the first gear 132.
In addition, the structure of the current collector 123 is not particularly limited. Referring to fig. 6, in an embodiment, the flow collecting member 123 includes an air outlet ring 124, the air supply opening 1231 is formed on the air outlet ring 124, and the rack 133 is disposed on an end of the air outlet ring 124 close to the air duct 122.

Further, referring to fig. 5 and 7, the vortex ring generating device 120 further includes a mounting bracket 127 mounted at the second air outlet 122b, the mounting bracket 127 has a mounting ring 128, the collecting member 123 is rotatably mounted in the mounting ring 128, and the first driving device 130 is mounted on the mounting bracket 127.
Specifically, the mounting ring 128 is located between the air duct 122 and the flow collector 123 to connect the air duct 122 and the flow collector 123. In view of the fact that the manifold 123 is rotatably installed in the mounting ring 128, in order to reduce friction between the manifold 123 and the mounting ring 128, a plurality of first stopper ribs 1281 may be provided in the mounting ring 128, and the plurality of first stopper ribs 1281 may be arranged at intervals in the circumferential direction of the mounting ring 128. Since the current collector 123 is rotatably engaged with the first limit ribs 1281, a contact area between the current collector 123 and the mounting ring 128 may be reduced, thereby reducing friction between the current collector 123 and the mounting ring 128, and making it easier for the current collector 123 to rotate.
Referring to fig. 7, in order to prevent the collecting member 123 from moving in the air blowing direction under the driving action of the air flow, a limiting portion 1282 may be disposed at one end of the mounting ring 128 close to the collecting member 123, and the limiting portion 1282 abuts against the collecting member 123 to limit the collecting member 123 in the air blowing direction. Specifically, the position-limiting portion 1282 may be, but is not limited to, an inward flange formed at one end of the mounting ring 128 near the current collector.

Since the current collecting member 123 abuts against the plurality of second stoppers, the contact area between the current collecting member 123 and the stopper 1282 can be reduced, so that friction between the current collecting member 123 and the stopper 1282 is reduced, and the current collecting member 123 can be more easily rotated. In this embodiment, the plurality of second limiting ribs 1283 are disposed on the surface of the limiting part 1282 close to the air duct 122, and the plurality of first limiting ribs 1281 are disposed on the inner edge of the limiting part 1282.
In addition to the above embodiments, in order to make the airflow blown out from the air supply opening 1231 more uniform, the vortex ring generating device 120 further includes a rectifying member 140 (as shown in fig. 5), wherein the rectifying member 140 may be disposed on a side of the vortex ring generating portion 126 close to the air duct 122; of course, the flow-straightening member 140 may be disposed on a side of the vortex ring generating portion 126 away from the air duct 122.
Specifically, the rectifying member 140 may be a rectifying plate, but is not limited thereto. The rectifying member 140 is used to rectify the air flow blown to the collecting member 123, which is beneficial to forming a stable vortex ring and realizing remote air supply, thereby making the indoor temperature distribution more uniform.
