Description

Technical Field

[0001] The invention relates to the technical field of air conditioning, and in particular to a vortex ring generating device, an air conditioning indoor unit and an air conditioner. Background Art

[0002] The existing air conditioner blows out the airflow after heat exchange through the conventional air vents of the air conditioner. The air outlet mode is conventional, and the airflow out of the conventional air vent is fixed and unchanged. Its radiation range is short and narrow, and it cannot achieve large-scale and long-distance air supply, which reduces the user experience.

[0003] By installing a vortex ring generating device on the air conditioner, long-distance air supply can be achieved. Specifically, by driving the airflow to flow periodically through the collector to form a vortex ring. The general way to drive the airflow to flow is usually to set a switch door at the air inlet of the collector, and set an air supply component on one side of the switch door. By controlling the periodic opening and closing of the switch door, the airflow is controlled to flow out periodically. This driving method has a relatively complex structure and requires the air supply component and the switch door to cooperate closely. It is prone to failure over time and has low reliability.

[0043] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0044] In addition, the meaning of “and / or” appearing in the full text includes three parallel solutions. Taking “A and / or B” as an example, it includes solution A, or solution B, or a solution in which both A and B are satisfied.

[0045] The present invention provides an air-conditioning indoor unit, which may be a cabinet-type air-conditioning indoor unit, a mobile air-conditioning indoor unit, a wall-mounted air-conditioning indoor unit, a window unit, etc.

[0046] In the embodiment of the present invention, Figures 1 to 4 As shown, the air conditioner indoor unit comprises a housing and a vortex ring generating device 2. The housing 1 has a heat exchange air duct 11, and a mounting opening 121 is provided on the housing 1. The vortex ring generating device 2 is mounted on the housing 1.

[0047] The vortex ring generating device 2 includes a collecting cylinder body. For details, please refer to Figure 5 and Figure 6 The current collecting cylinder body includes a wind tube 21 and a current collecting member 25. The wind tube 21 has an air supply end 212. The current collecting member 25 is arranged at the air supply end 212 of the wind tube 21, and an air supply port 250 is opened on the current collecting member 25. The air flow area of ​​the air supply port 250 is smaller than the cross-sectional area of ​​the air supply end 212. The air supply port 250 of the vortex ring generating device 2 is connected to the room through the installation port 121, so as to periodically send out the vortex ring airflow from the air supply port 250.

[0048] The wind tube 21 is roughly cylindrical, and in order to reduce wind resistance, the wind tube 21 is roughly cylindrical. It can be understood that the wind tube 21 can have an air inlet end and an air supply end 212, and the air flow periodically flows into the wind tube 21 from the air inlet end and is blown out through the air supply end 212. The air inlet end and the air supply end 212 can be respectively arranged at both ends of the wind tube 21, and can also be arranged on the adjacent two side walls of the wind tube 21. The wind tube 21 can also only have an air supply end 212, and the air flow periodically flows into the wind tube 21 from the air supply end 212, and then flows out from the air supply end 212. The collector 25 can have a variety of forms. In one embodiment, the collector 25 is a collector cover, and the cross-sectional shape of the collector cover can be circular, elliptical, rectangular, etc. In order to reduce wind resistance, the collector cover is roughly cylindrical, and an air supply port 250 is opened at one end of the collector cover. Optionally, the collector is gradually arranged from the end away from the air supply port 250 to the air supply port 250, so that the collector can collect the wind sent from the air supply port 250, and make the generation and blowing of the vortex ring smoother. In another embodiment, the collector 25 is a collector plate, which is installed on the air supply end 212 of the air cylinder 21, and the air supply port 250 is provided on the collector plate. In other embodiments, the collector 25 can also be formed by enclosing several plates, and the formation of the vortex ring can also be achieved by setting the air supply port 250 on one of the plates. When the airflow is periodically blown out through the air supply port 250, since the air flow area of ​​the air supply port 250 is smaller than the cross-sectional area of ​​the air supply end 212, a flow field distribution with slow peripheral flow velocity and large intermediate flow velocity can be formed, so that the air blown out of the air supply port 250 forms a vortex ring airflow, thereby achieving a longer air supply distance. Moreover, the vortex ring exchanges heat with the surrounding air during the transmission process, and the temperature difference between the vortex ring and the surrounding air is not large, which ensures that the vortex ring will not produce obvious feeling of overcooling or overheating when blowing on the human body, thereby improving comfort.

[0049] The current collecting member 25 and the wind tube 21 can be integrally formed or separately formed. It is understandable that when the current collecting member 25 and the wind tube 21 are separately formed, the current collecting member 25 and the wind tube 21 are sealed and connected. When the current collecting member 25 and the wind tube 21 are integrally formed, a virtual dividing line is divided by the junction of the wind tube 21 and the current collecting member 25. One side of the dividing line is the wind tube 21, and the other side is the current collecting member 25. The air supply end 212 of the wind tube 21 is formed at the dividing line. Undoubtedly, the air flow area of ​​the air supply end 212 is larger than the air flow area of ​​the air supply port 250 of the current collecting member 25. The extension direction of the outer wall surface of the current collecting member 25 and the wind tube 21 can be consistent, that is, the length extension line of the outer wall surface of the two is a straight line. At this time, the current collecting cylinder body is a complete shape without a transfer line. The extension directions of the outer wall of the current collecting member 25 and the wind tube 21 may also be inconsistent, that is, the length extension lines of the outer walls of the two are set at an angle. In this case, a transfer line will be formed at the connection between the current collecting member 25 and the wind tube 21.

[0050] See also Figure 6 and Figure 7 The vortex ring generating device 2 further includes a pushing member 22 and a rotating member 23. The pushing member 22 is movably disposed in the collecting cylinder body to have a first position away from the air supply port 250 and a second position close to the air supply port 250. Specifically, when the pushing member 22 moves from the first position away from the air supply port 250 to the second position close to the air supply port 250, the pushing member 22 compresses the air in the air cylinder 21 to form an airflow, thereby pushing the air out of the air supply port 250. The pushing member 22 reciprocates between the first position and the second position to periodically drive the airflow to flow through the air supply end 212 and blow out through the air supply port 250, thereby forming a vortex ring. In this embodiment, the rotating member 23 is rotatably connected to the pushing member 22, and a matching structure is provided between the rotating member 23 and the pushing member 22, so that when the rotating member 23 is driven to rotate, the pushing member 22 is driven to move between the first position and the second position. The rotational motion of the rotating member 23 is converted into the sliding motion of the pushing member 23 through a simple transmission method, thereby periodically pushing the airflow to flow toward the air supply end 213. The structure is simple, stable and reliable.

[0051] The matching structure can be in various forms, such as threads that match each other. Figures 7 to 10 The matching structure includes a guide member 220 and an arc guide rail 230, wherein a guide member 220 is provided on one of the rotating member 23 and the pushing member 22, and an arc guide rail 230 is provided on the other, and the arc guide rail 230 extends in a spiral curve along the circumference of the rotating member 23 or the pushing member 22, so that when the rotating member 23 is driven to rotate, the guide member 220 abuts against the arc guide rail 230 to drive the pushing member 22 to move between the first position and the second position.

[0052] In this embodiment, when the rotating member 23 rotates, the guide member 220 abuts against the arc guide rail 230, and the guide member 220 slides relatively along the arc guide rail 230 under the push of the arc guide rail 230, so as to drive the pushing member to move along the axial direction of the rotating member 23, thereby making the pushing member 22 move between the first position and the second position. Specifically, the rotating member 23 can be driven to rotate by the motor 3. In this way, the rotation action of the rotating member 23 is converted into the movement action of the pushing member 22 through a simple structure. When the pushing member 22 moves back and forth between the first position and the second position, it can periodically drive the airflow to flow through the air supply end 212 and blow out through the air supply port 250, thereby forming a vortex ring. Compared with the door opening and closing or other push-pull methods, this pushing method has a simpler and more stable structure, which is conducive to the formation of a vortex ring.

[0053] It can be understood that in one embodiment, the guide rail can be set to a groove shape, and the rotating member 23 rotates back and forth to realize the reciprocating movement of the pushing member 22 between the first position and the second position, thereby periodically driving the air flow to be blown out through the air supply port 250, thereby forming a vortex ring.

[0054] In this example, see Figure 6 , Fig.11 and Fig.12 , the guide member 220 cooperates with the arc-shaped guide rail 230 so that when the rotating member 23 is driven to rotate, the pushing member 22 is driven to move from the second position to the first position. The vortex ring generating device 2 also includes an elastic reset member 24, and the elastic reset member 24 is connected to the pushing member 22 to provide a restoring force so that the pushing member 22 returns from the first position to the second position. In this way, when the rotating member 23 rotates, the pushing member 22 is driven to move from the second position to the first position away from the air supply port 250, and the elastic reset member 24 accumulates force. Subsequently, under the elastic force of the elastic reset member 24, the pushing member 22 is quickly driven from the first position back to the second position close to the air supply port 250. Due to the slingshot effect, the moving speed of the pushing member is faster, which is more conducive to the formation of the vortex ring.

[0055] Based on the previous embodiment, please refer to Fig.11 and Fig.12 The elastic reset member 24 is a spring sleeved on the outer periphery of the push member 22, one end of the spring is connected to the push member 22, and the other end of the spring is connected to the collecting cylinder. In this way, the elastic force of the spring is used to provide the restoring force, the structure is simple, and the effect is good.

[0056] In one embodiment, see Figures 7 to 12 , the pushing member 22 is arranged in a cylindrical shape, the rotating member 23 is at least partially sleeved in the pushing member 22, the guide member 220 is arranged on the inner wall of the pushing member 22, and the arc guide rail 230 is arranged on the outer wall of the rotating member 23. In this way, when the rotating member 23 rotates, the guide member 220 is pressed to a position away from the air outlet 250 by the arc guide rail 230. In this embodiment, the guide member 220 and the arc guide rail 230 are arranged between the rotating member 23 and the pushing member 22, and the guide member 220 is pressed by the rotation of the arc guide rail 230 to drive the pushing member 22 to move, and the structure is stable. Further, the arc guide rail 230 has a bearing surface 231 away from the air outlet 250, and when the rotating member 23 is driven to rotate, the guide member 220 abuts against the bearing surface 231 of the arc guide rail 230. In this way, the guide member 220 is pressed by the bearing surface 231 of the arc guide rail 230.

[0057] Based on the previous embodiment, please refer to Figures 7 to 9 At least three arc-shaped guide rails 230 are provided, and at least three arc-shaped guide rails 230 are arranged at equal intervals along the outer circumference of the rotating member 23, and at least three guide members 220 are provided accordingly. In this way, multiple supporting points are provided between the rotating member 23 and the pushing member 22, and the relative position between the rotating member 23 and the pushing member 22 is more stable, reducing the pressure on the guide member 220 and the arc-shaped guide rails 230, making the vortex ring generating device 2 more durable.

[0058] Based on the previous embodiment, Figures 7 to 9 As shown. Each arc guide rail 230 has a cut-in end 232 close to the air outlet 250 and a separation end 233 away from the air outlet 250, and the cut-in end 232 of each arc guide rail 230 and the separation end 233 of the adjacent arc guide rail 230 overlap at least partially in the axial direction of the rotating member 23. In this embodiment, when the rotating member 23 is driven to rotate, each guide member 220 is supported correspondingly to each arc guide rail 230, and is gradually pushed to the first position during the rotation of the rotating member 23. At this time, the guide member 220 slides out from the separation end 233 of the arc guide rail 230, and moves along the axial direction of the rotating member 23 under the action of the elastic reset member 24, and moves to the second position. At this time, the guide member 220 abuts against the cut-in end 232 of the arc guide rail 230, and continues to be pushed by the arc guide rail 230, and moves to the first position again. In this way, the rotating member 23 continues to rotate, and through the pushing action of the arc-shaped guide rail 230 and the restoring action of the elastic restoring member 24 , the pushing member 22 is driven to reciprocate between the first position and the second position.

[0059] In one embodiment, if Fig.10 As shown, the guide member 220 is a roller bearing 26. In this way, the friction between the guide member 220 and the arc guide rail 230 is reduced, so that the relative movement between the rotating member 23 and the pushing member 22 is smoother and the noise is reduced.

[0060] For further information, see Fig.12 The wall surface of the current collecting member 25 opposite to the pushing member 22 is provided with a first magnetic attraction portion 251 and a second magnetic attraction portion 252, and the first magnetic attraction portion 251 and the second magnetic attraction portion 252 have the same polarity. In this way, when the pushing member 22 approaches the current collecting member 25, the repulsive force between the first magnetic attraction portion 251 and the second magnetic attraction portion 252 reduces the force between the pushing member 22 and the current collecting member 25, thereby playing a role of buffering and silencing.

[0061] In one embodiment, see Fig.11 and Fig.12 The rotating member 23 includes a rotating shaft 27, and a gear 31 is disposed on the rotating shaft 27. The gear 31 is used for driving connection with the motor 3. Specifically, the gear 31 and the motor 3 are meshed and transmitted through a driving gear to drive the rotating member 23 to rotate. A bearing 26 is fixed on the collecting cylinder, and the rotating shaft 27 is sleeved in the bearing 26. In this way, the rotating shaft 27 is driven to rotate in a simple way, and the rotating member 23 is rotatably supported by the bearing 26, so that the rotating member 23 is more stable.

[0062] The current collecting member 25 of the vortex ring generating device 2 is sleeved in the mounting opening 121, and partially extends out of the mounting opening 121 to form a scattered air outlet channel 122 between the outer wall surface of the current collecting member 25 and the inner wall surface of the mounting opening 121, and the scattered air outlet channel 122 is connected to the heat exchange air duct 11. The current collecting member 25 can guide the airflow blown out of the scattered air outlet channel 122, so that the mounting opening 121 opened on the panel 12 is fully utilized, so that the vortex ring airflow is blown out of the middle part of the mounting opening 121, and the heat exchange scattered airflow is blown out around, and the airflow blown out of the scattered air outlet channel 122 will not affect the vortex ring airflow. In this way, while the vortex ring accurately supplies air, the air supply distance is long, and the transmission efficiency is high, combined with the scattered air outlet, the air supply area of ​​the entire air conditioner indoor unit is wider, the air supply distance is longer, and the heat exchange efficiency is high, so the space temperature is more uniform and the comfort level is higher.

[0063] In one embodiment, please refer to Figures 1 to 4 The housing 1 includes a panel 12 and two side panels 13 connected to both sides of the panel 12. A mounting port 121 is provided on the panel 12. A main air outlet 131 is provided on at least one side panel 13. The main air outlet 131 is connected to the heat exchange air duct 11. The vortex ring generating device 2 is installed in the heat exchange air duct 11.

[0064] It can be understood that the two opposite side panels 13 connected to the two sides of the panel 12 refer to the side panels 13 located on the left and right sides of the entire housing 1. A main air outlet 131 can be opened on one of the side panels 13, or main air outlets 131 can be opened on both side panels 13. In order to make the air outlet range wider and the air outlet area larger, it is preferred that main air outlets 131 are opened on both side panels 13. The shape of the main air outlet 131 can be circular, oval, long strip, etc. In order to make the air outlet volume larger, it is preferably long strip. The panel 12 and the two side panels 13 can be integrally formed or separately formed. The main air inlet can be opened on the panel 12 and\or the two side panels 13, and can also be opened on the back panel of the housing 1. By opening the main air outlet 131 on the side panel 13, the conventional air supply airflow will not affect the vortex ring airflow. While making the air outlet area wide, the air supply distance long, and the air supply forms diverse, the air flow propagation efficiency is high, thereby improving the heat exchange efficiency of the room, making the temperature of the space more uniform, and thus improving comfort.

[0065] When the vortex ring generating device 2 is installed in the heat exchange air duct 11, the vortex ring air duct of the vortex ring generating device 2 and the heat exchange air duct 11 can be independent of each other, so that the air inlet end of the vortex ring generating device 2 is connected to the indoor room, and the vortex ring generating device 2 can circulate and blow out the indoor wind. Since the vortex ring airflow can realize long-distance air supply, the indoor temperature distribution is more uniform, and the indoor comfort is improved. The vortex ring air duct of the vortex ring generating device 2 can also be connected to the heat exchange air duct 11. At this time, the air inlet end of the vortex ring generating device 2 can be connected to the heat exchange air duct 11, and the vortex ring generating device 2 can introduce the airflow in the heat exchange air duct 11, so that the blown vortex ring airflow is the gas after heat exchange. Combined with the characteristics of the vortex ring long-distance air supply, the area far away from the indoor unit of the air conditioner can also realize heat exchange, thereby improving the heat exchange efficiency of the indoor space, making the room temperature more uniform, and improving the user comfort.

[0066] The present invention also proposes an air conditioner, which includes an air-conditioning indoor unit and an air-conditioning outdoor unit connected by a refrigerant pipe, wherein the specific structure of the air-conditioning indoor unit refers to the above-mentioned embodiment. Since the air-conditioning indoor unit adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0067] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
