Description

Technical Field

[0001] The invention belongs to the technical field of kitchen and bathroom appliances, and specifically relates to a magnetic suspension panel structure and a bathroom heater. Background Art

[0002] Yuba, also known as bathroom heater, generally combines a panel with a light-emitting screen and a ventilator to achieve the functions of lighting and warm air flow. Embedded Yuba covers the panel on the ventilator box. When warm air is needed, the motor drives the panel to move, thereby exposing the functional area for warm air blowing.

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

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

[0005] If sliding in two directions is to be achieved, two sets of motor modules are required to make the stepping linear motor slide in the X+Y axis, but this upper and lower layer structure occupies a large space in the box and is costly. Summary of the invention

[0006] In order to solve the shortcomings of the prior art, the present invention provides a magnetic suspension panel structure. The panel can slide along the track in a magnetic suspension under the drive of the motor module. The sliding process has low noise and good stability, and more area can be left to better realize the functions of ventilation and blowing. The present invention also provides a bathroom heater including the magnetic suspension panel structure.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0064] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0065] Example 1

[0066] refer to Figure 1-Figure 7This embodiment provides a magnetic suspension panel structure 100, including a panel 1, a motor module 2 and a base 3. Driven by the motor module 2, the panel 1 can be suspended on the base 3 and can slide relative to the base 3.

[0067] The panel 1 includes a panel body 11 and a light-emitting component 12, and the light-emitting component 12 is installed inside the panel body 11. A mounting position 111 is provided on the panel body 11, and the mounting position 111 is a slot structure. The light-emitting component 12 of this embodiment is a plurality of light strips, and the light-emitting component 12 is installed in the light-emitting cavity inside the panel body 11, so that the panel 1 is a full screen. In some embodiments, the panel body 11 is a rectangular structure, and then is matched and connected with a substrate that is also rectangular, and the panel body 11 is arc-shaped at the corners to facilitate better fitting and connection to the substrate 3 when not suspended. In other embodiments, the panel body 11 can be set to a triangular, regular polygonal, elliptical or circular structure according to the shape and the installation area reserved for the substrate installation base; the shape of the substrate continues to be set accordingly.

[0068] The motor module 2 includes a mover assembly 21 and a stator assembly 22. The motor module 2 of this embodiment is a magnetic suspension motor module 2, and the mover assembly 21 and the stator assembly 22 are contactless motors. After power is turned on, a magnetic field force is generated between the mover assembly 21 and the stator assembly 22, so that the mover assembly 21 can be suspended on the stator assembly 22. Specifically, the mover assembly 21 is installed on the mounting position 111, so that the mover assembly 21 can drive the panel 1 to slide; the stator assembly 22 includes a stator base 221 and a track 222, and the track 222 is arranged on the stator base 221.

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

[0070] The movable subassembly 21 is fixedly connected to the panel body 11 via the mounting position 111. Therefore, in this embodiment, it is necessary to counterweight and perform static balance on the panel body 11 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 driven by the movable subassembly 21. Static balance refers to correcting the balance of the movable subassembly in a stationary state so that the dynamic balance and static balance of the movable subassembly are on the same correction plane. Specifically, after the motor module 2 is powered on, the panel 1 is driven by the movable subassembly 21 to be suspended on the base surface 31, and then the motor module 2 drives the panel 1 to slide along the track 222.

[0071] The 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 body, and the guide groove 2223 is arranged between the first guide rail 2221 and the second guide rail 2222. In this embodiment, Figure 4 As shown, the track 222 is an L-shaped structure, and then the first guide rail 2221, the second guide rail 2222 and the guide groove 2223 are also L-shaped structures. Coil windings 223 are provided in the first guide rail 2221 and the second guide rail 2222. The coil windings 223 are multiple annular inductor wire windings. When current passes through the coil windings 223, a magnetic field is generated around the coil. The additional magnetic field can generate external force (attraction and repulsion) on the permanent magnet of the upper mover assembly, thereby maintaining a stable magnetic suspension state.

[0072] During actual installation, the panel is facing the blowing space below. In some embodiments, the magnetic levitation panel uses magnetic levitation technology to make the panel magnetically levitate below or in front of the substrate. In magnetic levitation technology, after the coil winding is energized, the eddy current generated on the surface of the magnet by the high-frequency electromagnetic field effect is used to achieve the suspension of the object. Magnetic levitation uses the suction and repulsion of the magnet in the magnetic field to make the object float in the air. Under appropriate spatial configuration, by adjusting the power of the high-frequency source, the electromagnetic force is greater than the gravity, and the panel is magnetically suspended downward.

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

[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 magnetic levitation inductor coils, but the first coil 2231 and the second coil 2232 are distributed differently in the guide rail. Specifically, in the first guide rail 2221 and the second guide rail 2222, the first coil 2231 is distributed along the first direction L1 (x-axis), and the second coil 2232 is distributed along the second direction L2 (y-axis). The first direction L1 is perpendicular to the second direction L2. For 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 coils 2231 are distributed from right to left, and the second coils 2232 are 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 consistent.

[0075] Based on the distribution of the first coil 2231 and the second coil 2232, the coil winding 223 is also L-shaped. In terms of 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 is disposed through the mover base 211. In some embodiments, both 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 connected to 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 , and the other end may be movably connected and limited in the guide groove 2223 .

[0079] The magnet assembly 212 includes a first magnet 2121 and a second magnet 2122, and the first magnet 2121 and the second magnet 2122 can be fixed on the mover base 211 by embedding or bonding. Correspondingly, the mover base 211 can be pre-opened with a magnet mounting groove to position and install the magnet assembly. The first magnet 2121 and the second magnet 2122 are both permanent magnets, and the first magnet 2121 and the second magnet 2122 surround to form a square magnetic circuit 210. On the magnetic circuit 210, the N pole and the S pole 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 the coil winding 223, the magnetic poles on the first side 2101 are arranged from left to right as: N pole-S pole-N pole-S pole; the magnetic poles on the second side 2102 are arranged from left to right as: S pole-N pole-S pole-N pole; the magnetic poles on the third side 2103 are arranged from top to bottom as: N pole-S pole-N pole-S pole; the magnetic poles on the fourth side 2104 are arranged from top to bottom as: S pole-N pole-S pole-N pole. Based on the above arrangement structure, in the magnetic circuit 210, the magnetic field along the first direction L1 (x axis) is symmetrical with the magnetic field along the second direction L2 (y axis).

[0081] The number of magnets on the four sides of the magnetic circuit 210 is the same, and 4 magnets are set. 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 vertically 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 with the magnetic field along the second direction L2. Combined with the mover assembly 21 having a square magnetic circuit 210, the mover assembly 21 can drive the panel 1 to suspend 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] Combined with reference Figure 4 , Figure 6 and Figure 7 The track 222 is provided with a first active area 224 and a second active area 225 connected to each other, that is, the L-shaped track 222 is divided into the first active area 224 and the second active area 225 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 movable base 211 is also a square structure, and its side length is d0. The side length of the movable base 211 is d0, and there is a relationship between 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 are greater than or equal to the side length d0 of the movable base 211. In this way, when the panel 1 covers the base surface 31, the movable subassembly 21 can fit tightly on the track 222; when the panel 1 is suspended on the base surface 31, the movable subassembly 211 also smoothly contacts part of the track 222 and slides along the track 222. Moreover, the movable subassembly 21 can turn along the x-axis and y-axis on the L-shaped track without rotating.

[0084] As described above, one end of the mounting column 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 column 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 column 213 is separated from the guide groove 2223, or continues to be inserted into the guide groove 2223, that is, the mounting column 213 is partially in contact with the guide groove 2223.

[0085] In the electrical connection structure, the mounting column 213 is provided with a wire hole 2131, and a cable (not shown) passes through the slot 32 of the base 3 and the wire hole 2131, and is connected to the light-emitting element 12, thereby powering the light-emitting element 12. In some embodiments, the light-emitting element 12 can also be powered wirelessly.

[0086] The magnetic levitation panel structure provided in this embodiment has a motor module that drives the panel to slide after being powered on, and the sliding process is smooth, stable, and low-noise. The movable subassembly drives the panel to slide, which can make more space available for better ventilation and blowing while saving space. The magnetic levitation panel structure uses a square movable subassembly that slides along the L-shaped stator assembly, and can move in two different directions of the x-axis and y-axis. Compared with conventional linear sliding, it has more adjustable sliding areas and occupies less space.

[0087] Example 2

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

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

[0090] The magnetic field simulation verification is performed on the square mover assembly 21 and the linear mover assembly 21A, and the reference Fig. 9 and Fig.10 The magnetic field intensity distribution and magnetic field intensity curves of the two are basically consistent; but after comparing the field intensity cloud map, compared with the linear mover assembly 21A, the magnetic field arrangement of the square mover assembly 21 is more uniform, which further proves 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 Figure 1-Figure 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), and the magnetic suspension panel structure 100 of Example 1, wherein the impeller 201, the heating element 202 and the power module are arranged in a base 3. The heating element 202 is a PCT thermistor, and 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 air flow.

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

[0094] like Fig.12 As shown in 12A, the panel 1 is covered on the base surface 31, and the bathroom heater provides lighting through the light-emitting element.

[0095] In 12B, the motor module 2 is powered on to drive the panel 1 to slide along the track. Specifically, the moving subassembly 21 drives the panel 1 to suspend relative to the base surface 31 and slide along the first direction L1 (x axis), and the 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 moving subassembly 21 drives the panel 1 to slide along the second direction L2 (y axis) relative to the base surface 31, 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 as needed to adjust the air outlet gap; when the air blowing work is not in progress, the panel covers the entire base surface to reduce dust or other foreign matter from entering the interior of the base and keep it clean.

[0098] The above contents are merely examples and illustrations of the structure of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, and these obvious replacement forms all belong to the protection scope of the present invention.
