Description

Technical Field

[0001] This utility model belongs to the technical field of kitchen and bathroom appliances, specifically relating to a magnetic levitation panel structure and a bathroom heater. Background Technology

[0002] A bathroom heater, also known as a bathroom ventilation fan, typically combines a panel with an illuminated screen and an exhaust fan to provide both lighting and warm airflow. An embedded bathroom heater has its panel concealed within the exhaust fan housing; when warm air is needed, a motor drives the panel to shift, revealing the area where warm air is blown.

[0003] Most bathroom heaters with movable panels on the market use a "stepper motor + lead screw" drive structure to push the panel to achieve the "sliding cover" effect. However, the "stepper motor + lead screw" drive structure has problems with wear and noise, and these problems become more obvious after long-term use.

[0004] In addition, in existing sliding bathroom heater products, the panel slides back and forth on one or both sides, such as sliding along the X-axis. During the movement, only one side of the area can be left empty, and the area is small, which is not conducive to air intake and blowing.

[0005] To achieve sliding in two directions, two sets of motor modules are required, allowing the stepper linear motor to slide within the X and Y axes. However, this upper and lower layer structure occupies a large space in the housing and is costly. Utility Model Content

[0006] To address the shortcomings of the existing technology, this invention provides a magnetic levitation panel structure. Driven by a motor module, the panel can slide magnetically along a track, exhibiting low noise and good stability during the sliding process, and freeing up more space for better ventilation and airflow functions. This invention also provides a bathroom heater / ventilation unit incorporating this magnetic levitation panel structure.

[0007] The technical effects to be achieved by this utility model are realized through the following technical aspects:

[0008] In a first aspect, this utility model provides a magnetic levitation panel structure, comprising:

[0011] The substrate includes a base surface and a groove formed on the base surface;

[0012] The center of gravity of the panel is located at the center of the mounting position; after the motor module is powered on, the panel is suspended on the base surface, and the motor module drives the panel to slide along the track.

[0016] In some embodiments, the magnet assembly includes a first magnet and a second magnet, the first magnet and the second magnet surrounding a square magnetic circuit; the N poles and S poles of the magnetic circuit are alternately arranged.

[0017] In some embodiments, the track has a first active area and a second active area that are interconnected; the first active area has a first width d1 along a second direction; and the second active area has a second width d2 along the first direction.

[0018] The moving base is a square structure with a side length of d0, and has the following relationship: d1=d2≥d0.

[0019] In some embodiments, when the coil winding is not energized, the other end of the mounting post is inserted into the guide slot;

[0020] When the coil winding is energized, the other end of the mounting post either separates from the guide slot or remains inserted into the guide slot.

[0021] In some embodiments, the mounting post is provided with a wire passage hole, through which a cable passes and is connected to the light-emitting element.

[0022] In some embodiments, the magnetic field along the first direction is symmetrical to the magnetic field along the second direction in the magnetic circuit.

[0023] In a second aspect, this utility model provides a bathroom heater, including an impeller, a heating element, and a power module, as well as the aforementioned magnetic levitation panel structure, wherein the impeller, the heating element, and the power module are disposed in the substrate;

[0024] When the bathroom heater does not provide a blower function, the panel covers the base surface;

[0025] When the bathroom heater provides airflow, the motor module is powered on, and the panel slides along the track according to a set path, revealing the functional area.

[0026] In summary, this utility model has at least the following advantages:

[0027] 1. The magnetic levitation panel structure provided by this utility model allows the motor module to drive the panel to slide along the track after being powered on.

[0064] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0065] Example 1

[0066] refer to Figures 1-7This embodiment provides a magnetic levitation panel structure 100, including a panel 1, a motor module 2 and a base 3. The panel 1 can be suspended on the base 3 and can slide relative to the base 3 under the drive of the motor module 2.

[0067] Panel 1 includes a panel body 11 and light-emitting elements 12, with the light-emitting elements 12 installed inside the panel body 11. A mounting position 111, which is a groove structure, is provided on the panel body 11. In this embodiment, the light-emitting elements 12 are multiple light strips, installed in a light-emitting cavity inside the panel body 11, making the panel 1 a full-screen display. In some embodiments, the panel body 11 has a rectangular structure, which is then connected to a rectangular base. The panel body 11 has rounded corners to facilitate a better fit and connection to the base 3 when not floating. In other embodiments, depending on the shape and the reserved mounting area on the base, the panel body 11 can be set as a triangular, regular polygonal, elliptical, or circular structure; the shape of the base is then correspondingly set.

[0068] The motor module 2 includes a mover assembly 21 and a stator assembly 22. In this embodiment, the motor module 2 is a magnetic levitation motor module 2, where the mover assembly 21 and stator assembly 22 operate without contact. Upon power-up, a magnetic field force is generated between the mover assembly 21 and the stator assembly 22, allowing the mover assembly 21 to levitate above the stator assembly 22. Specifically, the mover assembly 21 is mounted on the mounting position 111, enabling it to slide the panel 1. The stator assembly 22 includes a stator base 221 and a track 222, with the track 222 positioned on the stator base 221.

[0069] The base 3 is a box structure, including a base surface 31 and a groove 32 opened on the base surface 31. The opening direction of the groove 32 corresponds to the direction of the track 222.

[0070] The mover assembly 21 is fixedly connected to the panel body 11 via the mounting position 111. Therefore, in this embodiment, the panel body 11 needs to be counterweighted and statically balanced so that the center of gravity of the panel 1 is located at the center of the mounting position 111, so that it can be stably suspended above the base surface 31 under the action of the mover assembly 21. Static balancing refers to correcting the balance of the mover in a static state so that the dynamic balance and static balance of the mover are on the same correction plane. Specifically, after the motor module 2 is powered on, the panel 1 is suspended on the base surface 31 by the mover assembly 21, and then the motor module 2 drives the panel 1 to slide along the track 222.

[0071] Track 222 includes a first guide rail 2221, a second guide rail 2222, and a guide groove 2223. The guide groove 2223 is a through groove and is disposed between the first guide rail 2221 and the second guide rail 2222. In this embodiment, as... Figure 4 As shown, track 222 has an L-shaped structure, and consequently, the first guide rail 2221, the second guide rail 2222, and the guide groove 2223 also have L-shaped structures. Coil windings 223 are provided in both the first guide rail 2221 and the second guide rail 2222. The coil windings 223 consist of multiple ring-shaped inductive wire windings. When current flows through the coil windings 223, a magnetic field is generated around the coil. This additional magnetic field can exert external forces (attraction and repulsion) on the permanent magnet of the moving part assembly above, thereby maintaining a stable magnetic levitation state.

[0072] In actual installation, the panel faces downwards into the airflow space. In some embodiments, the magnetic levitation panel uses magnetic levitation technology to magnetically levitate the panel below or in front of the substrate. In magnetic levitation technology, the eddy currents generated on the surface of the magnet by the high-frequency electromagnetic field effect after the coil winding is energized achieve the levitation of the object. Magnetic levitation uses the attractive and repulsive forces of magnets in a magnetic field to make the object float in the air. With appropriate spatial configuration, by adjusting the power of the high-frequency source to make the electromagnetic force greater than gravity, magnetic levitation with the panel facing downwards can be achieved.

[0073] In some embodiments, the panel may also be suspended above the base during actual installation.

[0074] The coil winding 223 includes a first coil 2231 and a second coil 2232. Both the first coil 2231 and the second coil 2232 are magnetically levitation inductors, but their distribution in the guide rails differs. Specifically, in the first guide rail 2221 and the second guide rail 2222, the first coil 2231 is distributed along a first direction L1 (x-axis), and the second coil 2232 is distributed along a second direction L2 (y-axis). The first direction L1 is perpendicular to the second direction L2. Further reference... Figure 4 and Figure 6 The first direction L1 is from right to left, and the second direction L2 is from top to bottom. That is, the first coil 2231 is distributed from right to left, and the second coil 2232 is distributed from top to bottom. In the first guide rail 2221 and the second guide rail 2222, the coil spacing of the coil winding 223 is the same.

[0075] Based on the distribution of the first coil 2231 and the second coil 2232, the coil winding 223 is also L-shaped. In the control logic, the first direction L1 (x-axis) and the second direction (y-axis) of the L-shaped track are...

[0076] The mover assembly 21 includes a mover base 211, a magnet assembly 212, and a mounting post 213. The magnet assembly 212 is mounted on the mover base 211, and the mounting post 213 passes through the mover base 211. In some embodiments, the two ends of the mounting post 213 protrude from the upper and lower surfaces of the mover base 211; in other embodiments, the mounting post 213 protrudes from the side where the magnet assembly 212 is mounted, but does not protrude from the side that contacts the panel 1.

[0077] In this embodiment, one end of the mounting post 213 is connected to the mounting position 111 of the panel 1, and the other end is inserted into the guide groove 2223 in the track 222.

[0078] In some embodiments, one end of the mounting post 213 may be fixedly connected to the mounting position 111, while the other end is movably connected and confined in the guide groove 2223.

[0079] The magnet assembly 212 includes a first magnet 2121 and a second magnet 2122, which can be fixed to the mover base 211 by embedding or bonding. Correspondingly, the mover base 211 may have pre-formed magnet mounting slots for positioning and mounting the magnet assembly. Both the first magnet 2121 and the second magnet 2122 are permanent magnets, and they form a square magnetic circuit 210 around each other. On the magnetic circuit 210, the N poles and S poles are arranged alternately.

[0080] like Figure 7 As shown, on the square magnetic circuit 210, the magnetic poles on the side facing the track 222 and coil winding 223 are arranged from left to right as follows: N-S-N-S; on the second side 2102, the arrangement is: S-N-S-N; on the third side 2103, the arrangement is: N-S-N-S; and on the fourth side 2104, the arrangement is: S-N-S-N. Based on this arrangement, the magnetic field along the first direction L1 (x-axis) in the magnetic circuit 210 is symmetrical to the magnetic field along the second direction L2 (y-axis).

[0081] The magnetic circuit 210 has the same number of magnets on all four sides, with four magnets in each side. In some embodiments, the number of magnets can be set according to the actual electromagnetic and inductance requirements of the motor. The L-shaped track of the mover assembly 21 and the stator assembly 22 perpendicularly forms an L-shaped motor. When the mover assembly 21 runs on the track 222, the magnetic field along the first direction L1 is symmetrical to the magnetic field along the second direction L2. Combined with the square magnetic circuit 210 of the mover assembly 21, the mover assembly 21 can drive the panel 1 to levitate relative to the base surface 31 and slide along the L-shaped track 222. Specifically, the panel 1 first slides along the first direction L1, and then slides along the second direction L2.

[0082] Reference Figure 4 , Figure 6 and Figure 7 The track 222 has a first active area 224 and a second active area 225 that are interconnected, that is, the L-shaped track 222 is divided into a first active area 224 and a second active area 225 that are perpendicular to each other. Along the second direction L2, the first active area has a first width d1; along the first direction, the second active area has a second width d2.

[0083] The moving base 211 is also a square structure with a side length of d0. The side length d0 of the moving base 211 has the following relationship with the first width d1 and the second width d2: d1 = d2 ≥ d0. That is, the first width d1 of the first active area 224 and the second width d2 of the second active area 225 are equal and greater than or equal to the side length d0 of the moving base 211. Thus, when the panel 1 covers the base surface 31, the moving assembly 21 can fit tightly against the track 222; when the panel 1 is suspended above the base surface 31, the moving base 211 also smoothly contacts and slides along the track 222. Furthermore, the moving assembly 21 can bend along the x and y axes on the L-shaped track without needing to rotate.

[0084] As described above, one end of the mounting post 213 is connected to the mounting position 111 of the panel 1; when the coil winding 223 is not energized, that is, when the panel 1 covers the base surface 31, the other end of the mounting post 213 is inserted into the guide groove 2223; when the coil winding 223 is energized and the panel 1 is suspended on the base surface 31, the other end of the mounting post 213 is separated from the guide groove 2223 or continues to be inserted into the guide groove 2223, that is, the mounting post 213 is partially in contact with the guide groove 2223.

[0085] In the electrical connection structure, the mounting post 213 has a wire hole 2131. The cable (not shown in the figure) passes through the groove 32 of the base 3 and the wire hole 2131, and is connected to the light-emitting element 12, thereby supplying power to the light-emitting element 12. In some embodiments, the light-emitting element 12 can also be wirelessly powered.

[0086] The magnetic levitation panel structure provided in this embodiment allows the motor module to drive the panel to slide smoothly and stably with low noise after being powered on. The sliding motion of the panel by the moving part assembly frees up more space, improving ventilation and airflow while saving space. This magnetic levitation panel structure uses a square moving part assembly that slides along an L-shaped stator assembly, allowing movement along two different directions: the x-axis and the y-axis. Compared to conventional linear sliding, it offers a larger adjustable sliding area and occupies less space.

[0087] Example 2

[0088] Figure 8 This is a comparison diagram of the mover assembly and the linear mover assembly in this embodiment. For the distribution of the first magnet and the second magnet of the magnet assembly of the mover assembly 21 in this embodiment, as well as the magnetic circuit arrangement, please refer to the description of Embodiment 1, which will not be repeated here.

[0089] The linear mover assembly 21A is a common mover assembly for linear motors (cross-sliding linear motors) on the market. Its magnetic circuit is set on both sides. Specifically, the magnetic poles on the left side are arranged from top to bottom as: N pole-S pole-N pole-S pole; the magnetic poles on the right side are arranged from top to bottom as: S pole-N pole-S pole-N pole.

[0090] Magnetic field simulation verification was performed on the square moving part assembly 21 and the linear moving part assembly 21A, in conjunction with reference. Figure 9 and Figure 10 The magnetic field strength distribution and magnetic field strength curves of the two are basically the same; however, by comparing the field strength cloud maps, the magnetic field arrangement of the square mover assembly 21 is more uniform than that of the linear mover assembly 21A, which further confirms that the square mover assembly 21 cooperates with the stator assembly 22 with the L-shaped track to drive the panel to slide along the track.

[0091] Example 3

[0092] exist Figures 1-10 Based on reference Figure 11-13 A bathroom heater 200 includes an impeller 201, a heating element 202, and a power module (not shown in the figure), as well as the magnetic levitation panel structure 100 of Embodiment 1. The impeller 201, heating element 202, and power module are disposed in the base 3. The heating element 202 is a PCT thermistor. The impeller 201 is adjacent to the heating element 202 and can blow the heat generated by the heating element 202 to the outside in the form of hot airflow.

[0093] The base 3 is a box structure, with a base surface 31 and an air inlet 33. When the bathroom heater 200 does not provide the air blowing function, the panel 1 covers the base surface 31. When the bathroom heater 200 provides the air blowing function, the motor module 2 is powered on, and the panel 1 slides along the track according to the set path, exposing the functional area 205 and the air blowing area 206.

[0094] like Figure 12 As shown in 12A, panel 1 covers base surface 31, and the bathroom heater provides illumination through light-emitting elements.

[0095] In 12B, the motor module 2 is powered on, driving the panel 1 to slide along the track. Specifically, the mover assembly 21 causes the panel 1 to float relative to the base surface 31 and slide along the first direction L1 (x-axis), at which point the air blowing area 206 is exposed.

[0096] In 12C, the motor module 2 continues to drive the panel 1 to slide along the track. Specifically, the mover assembly 21 drives the panel 1 to slide relative to the base surface 31 along the second direction L2 (y-axis), exposing the functional area 205, such as the sensor 203 and the display screen 204.

[0097] The bathroom heater provided in this embodiment has a panel that can slide along the track as needed, and the suspension height can be adjusted to adjust the air outlet gap. When not blowing air, the panel covers the entire base surface, reducing the entry of dust or other foreign objects into the base and keeping it clean.

[0098] The above description is merely an example and illustration of the structure of this utility model, and while the description is quite specific and detailed, it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these obvious substitutions all fall within the protection scope of this utility model.
