Description

[Technical Field]

[0001] FIELD OF THE INVENTION This application relates to the field of air conditioning, and more particularly to air conditioning assemblies and bladeless fans. [Background technology]

[0002] In existing bladeless fans, the blowing member is generally designed as an integrated annular structure, which can only rotate as a whole and cannot realize various oscillation modes of blowing. Furthermore, because the blowing member is designed as a full-circumference annular structure, the wind needs to be transported along the entire annular structure, which increases the transport distance of the duct. As a result, the noise of the blowing member is louder and the wind speed is lower.

[0003] On the other hand, in existing electric fans, the base and the support are generally connected by a screw connection, while the conductive components inside them are connected by a plug. This plug-in electrical connection method requires the plug to be inserted before rotation, which makes the plug-in components susceptible to twisting and damage due to friction between the contact surfaces or the operator's operating force during rotation, resulting in a poor user experience. Furthermore, the screw connection does not allow for the installation of any sealing material on the screw connection surface, otherwise the screw cannot be turned, resulting in air leakage problems at the screw connection surface.

[0012] In order to make the objectives, technical solutions and advantages of the present application clearer, the following detailed description of the embodiments of the present application is given with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the embodiments of the present application can be arbitrarily combined. The air conditioning assembly of the present application can be used in various possible situations, such as a fan, a blower, a heater, etc.

As shown, the air conditioning assembly of the present application includes an air conditioning assembly 3 mounted on a support assembly 2. The support assembly 2 is mounted on a base assembly 1, and the air conditioning assembly 3 is mounted on the support assembly 2. Alternatively, the air conditioning assembly 3 may be mounted directly on the base assembly 1 without the support assembly 2. A fan may be provided within the base assembly 1, and the fan generates an airflow in a duct in the support assembly 2. The duct in the support assembly 2 is connected to the duct in the air conditioning assembly 3, allowing the airflow to be transported to the duct in the air conditioning assembly 3 and blown out through the air outlet of the air conditioning assembly 3. The air conditioning assembly 3 includes at least two air conditioning frames 31, each preferably having an arc-shaped structure. The at least two air flow frames 31 are connected to the support assembly 2, and cooperate to form an annular air flow surface of the air conditioning assembly. Each air flow frame 31 can rotate independently on the support assembly 2, enabling various modes of circulating airflow. By using the above solution, the air flow assembly is designed with multiple air flow frames, each connected to the support assembly and rotatable independently, enabling various oscillating modes of air flow of the air conditioning assembly. The air conditioning assembly of the present application achieves a three-dimensional air flow effect, significantly improving air circulation efficiency and air circulation efficiency, as well as enabling air flow from different angles. As will be understood by those skilled in the art, the annular air flow surface described herein refers to a surface that is not structurally continuous but forms an annular air flow surface, and may be a ring, a square ring, or any other possible annular shape.

[0014] As shown in FIGS. 1 to 3, 5, and 7, in some embodiments, the support column assembly 2 includes a first connecting base 21 and a support column 24. The first connecting base 21 is installed on the support column 24, and the duct of the first connecting base 21 communicates with the duct of the support column 24.

Specifically, the connecting member 32 is rotatably connected to the first connecting base 21, allowing the connecting member 32 to rotate around the axis of the connecting member 32 relative to the first connecting base 21. The duct within the connecting member 32 further communicates with the duct of the air transport assembly within the first connecting base 21, thereby realizing air guidance. By using the above solution, the air flow frame is connected to the support column by the connecting base and communicates with the duct, allowing air to be guided and blown, thereby ensuring the air flow efficiency and wind speed of the bladeless air conditioning assembly.

[0015] As shown in FIGS. 1 to 3, 5, and 7, in some embodiments, the first connection base 21 includes a fixed base 22 and a rotating base 23. The fixed base 22 is connected to the support assembly 2, thereby realizing duct communication. The rotating base 23 is installed on the fixed base 22 and is rotatable relative to the fixed base 22, thereby rotating the entire air blowing assembly. Specifically, the air transport assembly in the first connection base 21 includes an air transport member and a duct connecting member 216. The air transport member is installed in the rotating base 23 and connected to the duct connecting member 216, thereby realizing duct communication. The connecting member 32 is rotatably connected to the air transport member and is rotatable relative to the air transport member around its rotation axis.

By using the above solution, the duct in the connecting member 32 and the duct of the air transport member are connected to each other, and the duct of the duct connecting member 216 is designed to be connected to the duct of the air transport member and the duct of the support assembly 2, so that the airflow generated by the fan in the base assembly 1 can pass through the duct of the support 24, the duct connecting member 216, and the air transport member in order and enter the air blowing assembly, thereby realizing efficient circulation. The flow direction of the airflow is specifically shown as F in Figure 8.

[0016] As shown in FIGS. 3 to 7 , in some embodiments, the connecting member 32 and the first connecting base 21 are connected by a first drive mechanism, so that each blower frame 31 can rotate on the first connecting base 21 around the rotation axis of the connecting member. Rotation of the blower frame 31 on the first connecting base 21 around the rotation axis of the connecting member is shown in FIG. 9 , where the rotation angle a is 0° to 110°, preferably 40° to 60°. Specifically, the first drive mechanism includes a first motor 43 and a first gear set, where the first gear set is installed on the connecting member 32 and the first motor 43 is installed on the rotating base 23, or the first gear set is installed on the rotating base 23 and the first motor 43 is installed on the connecting member 32. Furthermore, the first gear set is power-transmittingly connected to the first motor 43, so that the first motor 43 drives the first gear set, thereby rotating the blower frame 31 around the rotation axis of the connecting member 32. Specifically, the first gear set includes a first driven gear 41 and a first driving gear 42. The first driven gear 41 is connected to the connecting member 32, and the first driving gear 42 is connected to the output shaft of the first motor 43. The first driven gear 41 and the first driving gear 42 mesh with each other to achieve power transmission cooperation. A motor bracket 46, an induction switch 47, and a switch bracket 471 are provided within the rotating base 23. The first motor 43 is fixedly installed on the motor bracket 46, and the induction switch 47 is installed on the switch bracket 471, thereby achieving operation detection. Magnets 5 are provided on the connecting member 32 and the fixed base 22, respectively. When the connecting member 32 rotates to a predetermined angle on the rotating base 23, the magnets 5 on the connecting member 32 and the magnets 5 on the fixed base 22 can detect each other, thereby achieving starting and stopping by electrical control.

[0017] As shown in Figures 11 to 14, in some embodiments, the rotating base 23 and the fixed base 22 are connected by a second drive mechanism, allowing the rotating base 23 to rotate relative to the fixed base 22, thereby moving the entire blower assembly so that it rotates around the axis of the first connecting base 21.The operation of the blower assembly 3 rotating around the axis of the first connecting base 21 is shown in Figure 10, and the rotation angle is 0° to 180°.In this way, circular blowing can be achieved by blowing air using each air outlet on the blower frame 31. Specifically, the second driving mechanism includes a second motor 48 and a second gear set, the second motor 48 is installed on the wind transport member, and the second gear set is installed in the fixed base 22, or the second gear set is installed on the wind transport member, the second motor 48 is installed in the fixed base 22, and the second gear set is transmission-connected to the second motor 48, so that the second motor 48 drives the second gear set to rotate the rotating base 23 on the fixed base 22. Specifically, the wind transport member includes an upper cover 214 for the wind transport member and a lower cover 215 for the wind transport member, and the upper cover 214 for the wind transport member and the lower cover 215 for the wind transport member are combined with each other to form the wind transport member. The rotating base 23 includes an upper cover 212 for the rotating base and a lower cover 213 for the rotating base, and the upper cover 212 for the rotating base and the lower cover 213 for the rotating base are combined with each other to form the rotating base 23. Furthermore, a motor support frame is provided on the upper cover 214 for the wind transport member, and the second motor 48 is fixedly installed on the motor support frame. Furthermore, the second gear set includes a second driven gear 49 and a second driving gear, and the second driven gear 49 may be an internal gear, and the second driven gear 49 is installed in the fixed base 22, and the second driven gear 49 and the second driving gear mesh with each other, and the second driving gear is connected to the output shaft of the second motor 48, thereby realizing cooperative transmission.

[0018] As shown in Figures 3, 5, and 11, in some embodiments, the air transport member is fixedly installed within the rotating platform 23, and includes an upper cover 214 for the air transport member and a lower cover 215 for the air transport member, which are connected to each other. One end of the connecting member 32 is connected to the air transport member via a bearing 44, which improves the support stability of the connecting member. A silicone ring 45 is provided between the connecting member 32 and the air transport member, which seals the gap between the connecting member 32 and the air transport member, preventing air leakage from the ducts of the connecting member 32 and the air transport member, thereby improving the speed and efficiency of airflow. The duct within the connecting member 32 is further connected to the duct within the airflow frame 31, thereby achieving airflow.

[0019] 1, 7, 9, and 10, in some embodiments, there are preferably two air blower frames 31, and each air blower frame 31 is connected to the rotating table 23 of the first connecting table 21 by its connecting member 32. The connecting member 32 of each air blower frame 31 is connected to the rotating table 23 by the first driving mechanism, thereby achieving independent rotation. In other words, each air blower frame 31 can rotate independently around the axis of its connecting member 32 on the rotating table 23, thereby realizing air blowing in various oscillation modes.

[0020] As shown in FIGS. 4, 5, and 10, in some embodiments, a plurality of air outlets 311 are spaced apart in the airflow frame 31, and each air outlet 311 is independently connected to a duct within the airflow frame 31. The airflow frame 31 may have an arc-shaped structure, a square structure, an elliptical arc structure, or the like. At least two airflow frames 31 are connected to the support assembly 2, respectively, to cooperate to form an annular airflow surface. The annular structure in this application is not limited to a circular annular structure and may also include various types of annular airflow surfaces, such as a square, polygonal, elliptical, or various irregular shapes. Specifically, at least two airflow frames 31 are connected to the rotating base 23 of the first connecting base 21, respectively, to form an annular airflow frame. The annular airflow frame can be rotated around a horizontal axis to achieve rotating airflow, as shown by r in FIG. 10.

[0021] As shown in Figures 3 and 4, in some embodiments, the air blower assembly 3 further includes an air guide member 35. The air guide member 35 is installed at the junction between the duct of the connecting member 32 and the duct of the air blower frame 31, thereby guiding air to both sides of the duct within the air blower frame 31. By using the above solution, the air guide member 35 is installed at the junction between the duct of the connecting member 32 and the duct of the air blower frame 31. The air from the duct of the connecting member 32 is guided by the air guide member 35 to quickly and evenly enter both sides of the duct within the air blower frame 31, thereby improving air blowing efficiency and making the air blown by the air blower frame 31 more uniform. Preferably, the cross sections of the air blower frame 31 and its duct each have a gradually narrowing cross section, and the air blowing opening 311 is located at the narrowest point of the duct of the air blower frame 31. This design helps to improve the blowing air speed.

[0022] As shown in FIGS. 3, 4, and 7, in some embodiments, a duct connector 321 is provided at one end of the connecting member 32, and an expanded duct section is formed within the duct connector 321. The duct connector 321 is connected to the airflow frame 31. Specifically, the duct connector 321 may be connected to the airflow frame 31 at an intermediate position, and the connection method may be a separate molding or an integral molding. The airflow guide member 35 is installed within the expanded duct section, and the expanded duct section forms an airflow duct, which communicates with the duct of the airflow frame 31 to guide air. By using the above solution, the expanded duct section not only facilitates the installation and distribution of the airflow guide member 35 by expanding the airflow space, but also enhances structural stability by expanding the connection surface between the duct connector 321 and the airflow frame 31.

[0023] As shown in FIGS. 4 and 15 , in some embodiments, the cross section of the air guide member 35 has a rhomboidal structure. Both sides of the air guide member 35 are symmetrical, each forming an arc-shaped air guide surface. An air guide duct is formed between the arc-shaped air guide surface and the inner wall of the duct expansion section, and the air guide duct communicates with the duct of the air blower frame 31. Preferably, the duct expansion section communicates with the duct of the air blower frame 31. Specifically, the duct expansion section may communicate with an intermediate position of the duct of the air blower frame 31 and is used to communicate with the duct. Specifically, the air guide duct includes a first air guide duct 324 and a second air guide duct 325. The first air guide duct 324 communicates with one side of the duct of the air blower frame 31, and the second air guide duct 325 communicates with the other side of the duct of the air blower frame 31. This allows air to be guided along both sides of the duct of the air blower frame 31, resulting in more uniform airflow.

[0024] As shown in FIGS. 4 and 19 , in some embodiments, the air blower frame 31 is provided with a plurality of air outlets 311, and the air outlets 311 may have an elongated structure. Preferably, the plurality of air outlets 311 are uniformly arranged along the length of the air blower frame 31 and are located on the end faces of the air blower frame 31. An air blower duct 323 is provided within the air blower frame 31, and the plurality of air outlets 311 are each in communication with the air blower duct 323. Specifically, an air guide rib is provided at the position of each air outlet 311 within the air blower duct 323. With this design, by setting the air guide ribs to different lengths or shapes, the airflow rate of the air outlets can be adjusted based on the distance from the air outlets to the duct connector, allowing the air within the air blower duct 323 to be uniformly discharged through the air outlets 311, thereby solving the problem of air stagnation within the duct of the air blower frame 31.

[0025] As shown in Figures 4 and 7, in some embodiments, the airflow frame 31 has an arc-shaped structure, preferably a semicircular arc-shaped structure. The airflow frame 31 is designed with an arc-shaped structure, and the airflow duct within the airflow frame 31 is also an arc-shaped duct, with the width of the arc-shaped duct gradually decreasing from the connection point between the connecting member and the airflow frame 31 to both sides. This design allows the airflow volume of each airflow port 311 to gradually decrease as it passes through. In the airflow assembly according to the present application, the airflow frame is designed with an arc-shaped structure, which shortens the airflow duct and allows the airflow entering the airflow duct to be quickly discharged, thereby increasing the airflow speed, reducing noise, and avoiding the problem of airflow stagnation caused by an excessively long airflow duct.

[0026] 19, in some embodiments, the air blower assembly 3 further includes an air blower frame cover plate 33 and an air guide cover plate 34, which may be integrally molded or separately assembled. The air guide cover plate 34 is installed within the duct of the air blower frame 31 and forms a sealing duct with the duct of the air blower frame 31, thereby improving air guide efficiency and air blowing efficiency. The duct within the air blower frame 31 is the air blow duct 323. The air blower frame cover plate is installed outside the air guide cover plate and covers it, fulfilling the roles of overall sealing, protection, and decoration.

[0027] As shown in FIGS. 1 and 5 , in some embodiments, a wind transport assembly is provided in the first connection base 21, and the other end of the connection member 32 is connected to the first connection base 21, thereby connecting the duct of the connection member 32 to the duct in the wind transport assembly. As shown in FIGS. 16 and 17 , in some embodiments, the base assembly 1 includes a first connection member and a first conductive member, and the first conductive member is attached to the first connection member. The support assembly 2 includes a second abutting member and a second conductive member, and the second conductive member is attached to the second abutting member. Specifically, the first connection member and the second abutting member are detachably engaged by rotation, thereby electrically connecting the first conductive member and the second conductive member. In the connection assembly according to the present application, the first connection member and the second abutting member are designed to be rotatably and directly connected, which facilitates assembly and disassembly, facilitates packaging and transportation, makes the structure simpler and more practical, and facilitates electrical connection.

[0028] As shown in FIGS. 16, 17, and 18, in some embodiments, the first connecting member is a support frame 13, and a first duct is provided on the first connecting member. The second abutting member is a second connecting base 25, and a second duct 251 is provided on the second abutting member. Specifically, the support frame 13 and the second connecting base 25 are connected by rotation, and the first duct 18 and the second duct 251 are connected to each other, thereby realizing air guidance. Furthermore, the support column assembly 2 further includes a support column 24, and the duct in the support column 24 is connected to the second duct 251 of the second connecting base 25. In the connection assembly according to the present application, the first connecting member and the second abutting member are rotatably connected to each other, thereby realizing a misaligned seal and preventing air leakage from occurring in the duct structure between the first connecting member and the second abutting member.

[0029] As shown in FIGS. 16, 17, and 18, in some embodiments, the first connecting member is a support frame 13, which is provided with a support wall 131. The first duct is disposed at the vertical center of the support frame 13 and is located inside the support wall 131. The second abutting member is a second connecting base 25, which is provided with a second duct at the vertical center of the second connecting base 25. The support wall 131 and the second connecting base 25 are removably connected to each other by an engaging structure. Specifically, the engaging structure includes an engaging groove and a boss 252, and the boss 252 and the engaging groove are engaged with each other by rotation. Preferably, the engaging groove is disposed on a side wall of the support wall 131, and the boss 252 is disposed on a side wall of the second connecting base 25. The boss 252 is inserted into the engaging groove vertically and can be engaged with the engaging groove by rotating it horizontally clockwise, thereby achieving a sealed connection. Preferably, there are at least three bosses 252 to improve the stability and sealing of the connection. By using the above solution, the support frame 13 and the second connecting base 25 are connected by rotation, thereby realizing a sealed connection and preventing wind leakage from occurring in the duct.

[0030] As shown in FIGS. 16, 17, and 18, in some embodiments, the first conductive member is mounted on the support frame 13, and the second conductive member is mounted on the second connection base 25. Specifically, the first conductive member is a contact plate 15, which may have a copper plate structure. The contact plate 15 may be mounted on the support frame 13 and on the inner end surface of the support wall 131. The second conductive member is a conductive plate 28, which may be mounted on the second connection base 25 and on the bottom surface of the second connection base 25. Specifically, a contact groove is formed in the contact plate 15, and an extendable copper pin 281 is provided on the conductive plate 28. By using the above solution, when the second connection base 25 is rotated to be attached to the support frame 13, the copper pin 281 can reach the position of the contact groove through rotation and make contact with the contact groove, thereby achieving an electrical connection.

[0031] 16, 17, and 18, in some embodiments, the support column assembly 2 further includes a conductive plate presser plate 240 that is crimped to the second connection base 25, and the conductive plate 28 is sandwiched between the conductive plate presser plate and the second connection base 25. Preferably, the conductive plate presser plate has an annular structure, and is provided with through-holes through which the copper pins 281 can pass. By using the above solution, the conductive plate presser plate is designed to crimp the conductive plate 28 to the second connection base 25, which not only ensures the connection and fixation of the conductive plate 28, but also increases the strength of the second connection base 25 and prevents the second connection base 25 from being damaged due to excessive rotation.

[0032] 16, 17, and 18, in some embodiments, the base assembly 1 further includes a seal member 14, which may be a silicone ring. The seal member 14 is installed on the support frame 13, and the contact plate 15 is sandwiched between the seal member 14 and the support frame 13. In this manner, the support frame 13 and the second connection base 25 can be clamped together when engaged, preventing air leakage in the duct between the support frame 13 and the second connection base 25. Specifically, the contact plate 15 may be sandwiched between the seal member 14 and the end face of the support frame 13. The seal member 14 has an opening groove that fits into the contact plate 15, allowing the copper pin 281 on the conductive plate 28 to pass through the opening groove and contact the contact plate 15.

[0033] As shown in FIGS. 16, 17, and 18, in some embodiments, the support frame 13 and the second connecting base 25 are further detachably connected by a restricting member to prevent accidental separation between the support frame 13 and the second connecting base 25. The restricting member serves to prevent erroneous operation, and the support base 27 is provided with unlock and lock marks. Specifically, the restricting member includes an elastic restricting pin and an unlocking hole, with the restricting pin fitting into the unlocking hole. Preferably, the unlocking hole is located on the support base 27 and faces the restricting pin. The restricting pin is attached to the support frame 13 by a spring, achieving an extension / retraction function. By using the above solution, when the support frame 13 and the second connecting base 25 are rotated and clamped to a predetermined angle, the restricting pin engages with the unlocking hole, thereby achieving locking. When unlocking is required, the restricting pin can be pushed along the unlocking hole with a pin to disengage it from the unlocking hole, and the second connecting base 25 can be rotated to achieve unlocking.

[0034] In the air conditioning assembly according to the present application, the air blower assembly includes multiple air blower frames, each of which is designed to rotate independently to blow air, thereby enabling various oscillation modes and air blowing from different angles, thereby improving the air circulation effect, significantly increasing the air stirring and circulation efficiency, and enhancing the three-dimensional air blowing effect of the air conditioning assembly and the user experience. Compared to a single strip-shaped air blower assembly, the annular air blower assembly can achieve a more uniform and gentler air blowing effect.

[0035] In the air conditioning assembly of the present application, the blower frame and the connecting base are designed to be rotatable relative to each other, while maintaining communication of the duct structure, thereby effectively improving the blower air speed and volume, and improving the energy efficiency of the product.

[0036] The present application describes a design in which the first connecting member and the second abutting member rotate before electrical connection, facilitating assembly and removal, and facilitating packaging and transportation. This not only avoids problems with friction or twisting damage caused by rotation of existing plug-in members, but also improves the sealing between the first connecting member and the second abutting member, allowing for the installation of sealing members on the connection surfaces and improving the sealing effect of the ducts within the first connecting member and the second abutting member. The use of the above connection assembly in the electric fan of the present application not only simplifies the product structure, reduces costs, and facilitates product packaging and transportation, but also effectively prevents damage to the electrical connection members and improves the user experience of the product.

[0037] The above are embodiments disclosed in the present application, but the above contents are merely embodiments used to facilitate understanding of the present application and are not intended to limit the present application. Those skilled in the art may make any modifications and changes to the embodiments and details without departing from the spirit and scope disclosed in the present application, but the scope of protection of the invention of the present application shall still be in accordance with the scope defined in the accompanying utility model registration claims.
