Description

Technical Field

[0001] This disclosure pertains to the field of household appliance technology, and specifically relates to a bathroom heater panel and a bathroom heater. Background Technology

[0002] A bathroom heater is a common household appliance used in bathrooms, which usually integrates a heating function.

[0003] Nowadays, bathroom heaters typically consist of a face mask, an air supply unit, a drive assembly, and a door. The face mask has air outlets, and the air supply unit blows out warm air; the air outlets of the air supply unit are connected to the air outlets of the face mask. The drive assembly is connected to the door, and it can move the door to switch the air outlets of the face mask between fully closed and fully open.

[0004] Currently, bathroom heaters typically offer multiple heating levels, which are adjusted by controlling the speed of the motor inside the air supply unit. However, in practical applications, when a user selects the lowest heating level, the motor inside the air supply unit operates at its lowest speed. In this case, the airflow reaching the user's location may still exceed the user's required airflow, limiting the adjustable range of the bathroom heater's airflow. Summary of the Invention

When the door is in the first stopped position, the door covers two-thirds of the air outlet; When the door is in the fourth stopped position, the door covers one-third of the air outlet.

[0008] In one possible implementation, the plurality of stopping positions further includes a fifth stopping position, wherein when the door is in the fifth stopping position, the door is misaligned with the air inlet and blocks the air outlet.

[0009] In one possible implementation, the bathroom heater panel further includes a position detection component, which includes multiple Hall sensors and a permanent magnet. The multiple Hall sensors are spaced apart along a first direction and are respectively connected to the face shield, and the permanent magnet is connected to the door. The controller is electrically connected to each of the plurality of Hall sensors and is also used for: The actual rotation angle of the motor is determined based on the magnetic field distribution information detected by the multiple Hall sensors; The correction rotation angle is determined based on the actual rotation angle and the target rotation angle; The output shaft of the motor is controlled to rotate by the correction rotation angle.

[0010] In one possible implementation, the plurality of Hall sensors are located on the side of the mask facing away from the door body; The permanent magnet is located on the side of the door closer to the mask.

[0011] In one possible implementation, the mask has a receiving groove on the side wall near the door, and the permanent magnet is located in the receiving groove when the door is in contact with the mask.

[0012] In one possible implementation, the mask includes a mask body and a mounting base, the mask body having a clearance opening, and the mounting base being located at the edge of the clearance opening and connected to the side of the mask body facing away from the door. One end of the first connecting rod is rotatably connected to the mounting base, and the other end of the first connecting rod passes through the clearance opening.

[0013] In one possible implementation, the other end of the first link is rotatably connected to the door body; The drive assembly further includes a second link, which is arranged parallel to the first link, and both ends of the second link are rotatably connected to the mounting base and the door body, respectively.

[0014] In one possible implementation, the plane formed by the first rotation axis of the first link and the second rotation axis of the second link is parallel to the mask body.

The controller can control the output shaft of the motor to rotate by a target rotation angle, thereby moving the door between a fully open position, a fully closed position, and a first stop position. When the door is in the first stop position, the door can partially block the air outlet, thereby partially blocking the warm airflow output by the air supply device, thus reducing the amount of air reaching the user's location and improving the adjustable range of the bathroom heater's air supply volume.

[0024] Bathroom heaters, as common household appliances in bathrooms, are becoming increasingly widely used. They typically integrate heating functions to provide warmth to the bathroom during autumn and winter. With the continuous development of bathroom heater technology, fan-type bathroom heaters are gradually replacing lamp-type heaters, becoming the mainstream choice in the industry. In this disclosure, unless otherwise specified, "bathroom heater" generally refers to a fan-type bathroom heater. Currently, bathroom heaters typically consist of a heater panel and a ventilation unit. The heater panel includes a faceplate, a drive assembly, and a door. The faceplate has ventilation openings, and the ventilation unit blows out warm air, with the air outlet of the ventilation unit connected to the ventilation openings. The drive assembly is connected to the door, enabling the door to move and switch the ventilation openings between fully closed and fully open. Currently, bathroom heaters typically offer multiple heating levels, which are adjusted by controlling the speed of the motor within the ventilation unit. However, in practical applications, when a user selects the lowest heating setting, the motor inside the air supply device runs at its lowest speed. At this time, the air volume reaching the user's location may still exceed the air volume required by the user, causing the user to feel "scorching heat" when using the bathroom heater. The adjustable range of the air supply volume of the bathroom heater is limited.

[0025] To address the aforementioned technical problems, this disclosure provides a bathroom heater panel. For example... Figure 1 As shown, the bathroom heater panel includes a faceplate 1, a door 2, a drive assembly 3, and a controller 4.

[0026] See Figure 1 The face mask 1 has a plate-like structure and can be rectangular in shape. The face mask 1 is typically installed on the ceiling of a bathroom. The edges of the face mask 1 have flanged structures extending in the same direction, which abut against the walls of pre-drilled mounting holes in the bathroom ceiling to improve the stability of the connection between the face mask 1 and the bathroom ceiling. See also... Figure 1 And refer to Figure 2 The face mask 1 has an air outlet 112, which can be rectangular in shape and extends through two opposite walls in the thickness direction of the face mask 1. In some examples, the face mask 1 also includes a grille located on the side of the face mask 1 away from the ground, and the grille is arranged opposite to the air outlet 112. By providing the grille, foreign objects such as hair can be prevented from entering the air supply device through the air outlet 112 to a certain extent, thereby extending the service life of the air supply device.

[0027] The door 2 can have a rectangular plate structure, and the size of the door 2 is larger than the size of the air outlet 112. That is, the length and width of the door 2 are larger than the air outlet 112, so as to ensure that when the door 2 is attached to the mask 1, the door 2 can completely cover the air outlet 112.

[0028] See Figure 1 and Figure 2 The drive assembly 3 includes a motor 31 and a first connecting rod 32. The motor 31 is located on the side of the face shield 1 away from the ground and is connected to the face shield 1. One end of the first connecting rod 32 is connected to the output shaft of the motor 31, and the other end of the first connecting rod 32 is connected to the door 2. It is easy to understand that when the motor 31 is running, its output shaft can rotate forward or backward, thus enabling the motor 31 to drive the first connecting rod 32 to swing along a first or second circumferential direction, thereby moving the door 2. In some examples, the bathroom heater panel includes two motors 31 and two first connecting rods 32, such as... Figure 1 As shown, two motors 31 are spaced apart along the length of the door body 2, and each motor 31 is connected to the face mask 1. One end of each first link 32 is connected to the output shaft of a corresponding motor 31, and the other end of each first link 32 is connected to one side of the door body 2 along its length. This improves the smoothness of the door body 2's movement. In some examples, the other end of the first link 32 is rotatably connected to the door body 2. This prevents the door body 2 from interfering with the face mask 1 during movement, thereby preventing deformation of the door body 2.

[0029] See also Figure 1 The controller 4 is located on the side of the mask 1 away from the ground and is connected to the mask 1. The controller 4 is electrically connected to the motor 31 and is used to: determine the target rotation angle based on the gear adjustment command, and control the output shaft of the motor 31 to rotate by the target rotation angle, so that the door 2 moves between multiple stopping positions. These multiple stopping positions include a first stopping position, a fully open position, and a fully closed position, such as... Figure 7As shown, when the door 2 is in the first stopped position, the door 2 partially obstructs the air outlet 112. When the door 2 is in the fully open position, the door 2 does not obstruct the air outlet 112. When the door 2 is in the fully closed position, the door 2 is attached to the side of the cover 1 closest to the ground and completely covers the air outlet 112. In some examples, the bathroom heater also includes a control panel (also called an operation panel). The controller 4 is communicatively connected to the control panel, and the control panel can send a gear adjustment command to the controller 4 in response to the user's gear selection operation. The controller 4 receives the gear adjustment command and determines the target rotation angle based on the gear adjustment command and the current angle of the output shaft of the motor 31. It then controls the output shaft of the motor 31 to rotate by the target rotation angle. The rotation of the output shaft of the motor 31 by the target rotation angle causes the first connecting rod 32 to swing, thereby moving the door 2 from the previous stopped position to the next stopped position, that is, enabling the door 2 to move between multiple stopped positions. In other examples, controller 4 is communicatively connected to a terminal device, such as a smartphone or tablet. The terminal device can send a gear adjustment command to controller 4 in response to the user's gear selection operation. The specific process by which controller 4 controls the rotation of the output shaft of motor 31 after receiving the gear adjustment command can be found above and will not be repeated here.

[0030] Using the technical solution provided in this embodiment, for a bathroom heater using this panel, the air outlet 112 of the cover 1 is used to connect with the air outlet of the air supply device. The controller 4 can control the output shaft of the motor 31 to rotate by a target rotation angle, so that the door 2 moves between a fully open position, a fully closed position and a first stop position. When the door 2 is in the first stop position, the door 2 can partially block the air outlet 112, thereby partially blocking the warm airflow output by the air supply device, thereby reducing the amount of air reaching the user's location and improving the adjustable range of the bathroom heater's air supply volume.

[0031] The following is a detailed description of the specific structure of the bathroom heater panel: In some possible embodiments, the bathroom heater panel is also used to be adapted to ventilation equipment.

[0032] like Figure 3As shown, the mask 1 also has an air inlet 111, which penetrates two opposite walls in the thickness direction of the mask 1. The air inlet 111 and the air outlet are spaced apart along a first direction X. The air inlet 111 of the mask 1 is connected to the air inlet of the ventilation device. The first direction X can be the width direction of the mask 1. The shape of the air inlet 111 can be rectangular, and the air inlet 111 and the air outlet 112 can be arranged in parallel. In some examples, the mask 1 also includes a grille, located on the side of the mask 1 away from the ground, and arranged opposite to the air inlet 111 and the air outlet 112, respectively. Thus, by providing the grille, foreign objects such as hair can be prevented from entering the ventilation device through the air inlet 111 and the air supply device through the air outlet 112 to a certain extent, thereby improving the service life of the ventilation device and the air supply device.

[0033] In some examples, multiple stopping positions also include a second stopping position, such as Figure 4 and Figure 5 As shown, when the door 2 is in the second stopped position, the door 2 blocks part of the air inlet 111 and the door 2 blocks the air outlet 112.

[0034] In practice, bathroom heaters can also integrate ventilation functions to remove moisture from the bathroom and maintain visibility. Related technologies typically offer multiple ventilation levels, adjusted by controlling the speed of the motor within the ventilation unit. However, in real-world applications, when the user selects the lowest ventilation level, the motor operates at its lowest speed. Even at this setting, the ventilation efficiency may still be relatively high, causing warm air to be quickly extracted. This necessitates restarting the ventilation system for the next user, resulting in higher overall energy consumption and limiting the adjustable range of ventilation provided by the bathroom heater.

[0035] Using the technical solution provided in this embodiment, for a bathroom heater using this panel, the air inlet 111 of the cover 1 is connected to the air inlet of the ventilation device. The controller 4 can control the output shaft of the motor 31 to rotate by a target rotation angle, thereby causing the door 2 to move between a fully open position, a fully closed position, a first stop position, and a second stop position. When the door 2 is in the second stop position, the door 2 can block the air outlet 112 and partially block the air inlet 111, thereby partially blocking the airflow from the bathroom to the ventilation device, thus reducing the rate at which warm air is extracted from the bathroom and improving the adjustable range of the bathroom heater's ventilation volume.

[0036] In some possible embodiments, the door 2 can block the air inlet 111 at at least two stopping positions, and the proportion of blocking of the air inlet 111 is different when the door 2 is in these two stopping positions. Correspondingly, the door 2 can block the air outlet 112 at at least two stopping positions, and the proportion of blocking of the air outlet 112 is different when the door 2 is in these two stopping positions.

[0037] In some examples, the aforementioned multiple stopping positions also include a third stopping position and a fourth stopping position.

[0038] Among them, such as Figure 5 As shown, when door 2 is in the second stopped position, door 2 blocks two-thirds of the air inlet 111 and completely blocks the air outlet 112. Figure 6 As shown, when door 2 is in the third stopped position, door 2 blocks one-third of the air inlet 111 and completely blocks the air outlet 112. Figure 7 As shown, when door 2 is in the first stopped position, door 2 does not block the air inlet 111, but blocks two-thirds of the air outlet 112. Figure 8 As shown, when the door 2 is in the fourth stopping position, the door 2 does not block the air inlet 111, but blocks one-third of the air outlet 112.

[0039] Combination Figure 2 See also Figures 5 to 8 During implementation, the door 2 remains attached to the mask 1. At this time, the door 2 is in the fully closed position. As the output shaft of the motor 31 rotates in the forward direction, the first connecting rod 32 swings along the first circumferential direction. The door 2 first moves from the fully closed position to the second stopping position. As the output shaft of the motor 31 continues to rotate in the forward direction, the first connecting rod 32 continues to swing along the first circumferential direction. The door 2 moves sequentially to the third stopping position, the first stopping position, the fourth stopping position, and the fully open position.

[0040] In some possible embodiments, such as Figure 9 As shown, the multiple stopping positions also include a fifth stopping position.

[0041] When the door 2 is in the fifth stopping position, the door 2 and the air inlet 111 are misaligned, that is, the door 2 does not block the air inlet 111, and the door 2 completely blocks the air outlet 112.

[0042] Using the technical solution provided in this embodiment, for a bathroom heater using this panel, the user can trigger the corresponding gear adjustment command based on the terminal device or control panel, thereby controlling the output shaft of the motor 31 to rotate via the controller 4, and driving the door 2 to move to the fifth stopping position via the first connecting rod 32. Thus, when the bathroom heater is in ventilation mode, the door 2 can block the air outlet 112 of the cover 1, preventing moisture from entering the air supply equipment through the air outlet 112, thereby extending the service life of the air supply equipment.

[0043] The following is an exemplary description of the switching process of the door 2 between the above-mentioned multiple stopping positions: In some possible embodiments, the bathroom heater includes a control panel mounted on the bathroom wall. The control panel may have multiple operating controls, each of which, when pressed, triggers a corresponding speed adjustment command to the controller 4. The control panel may also have a display screen showing multiple operating controls, each of which, when clicked, triggers a corresponding speed adjustment command to the controller 4.

[0044] In some examples, multiple operation controls include a first ventilation level control, a second ventilation level control, a third ventilation level control, a first heating level control, a second heating level control, and a third heating level control. The ventilation volume of the bathroom heater corresponding to the first, second, and third ventilation level controls gradually increases, as does the air supply volume of the bathroom heater corresponding to the first, second, and third heating level controls. Furthermore, after the first, second, and third ventilation level controls are clicked or selected, the door 2 can ultimately stop at the second, third, and fifth stopping positions, respectively. After the first, second, and third heating level controls are clicked or selected, the door 2 can ultimately stop at the first stopping position, the fourth stopping position, and the fully open position, respectively. In some examples, multiple operation controls also include a close control; after the close control is clicked or selected, the door 2 can ultimately stop at the fully closed position.

[0045] Taking the initial state of the door being fully closed as an example, the user selects to click or press the second ventilation position. The control panel sends the corresponding gear adjustment command of the second ventilation position control to the controller 4. After receiving the gear adjustment command, the controller 4 determines the target rotation angle based on the angle of the output shaft of the motor 31 when the door 2 is in the fully closed position and the angle of the output shaft of the motor 31 when the door 2 is in the third stationary position. It then controls the output shaft of the motor 31 to rotate by the target rotation angle. Thus, under the swing action of the first link 32, the door 2 switches from the fully closed position to the third stationary position.

[0046] Subsequently, the user selects or presses the first ventilation gear control. The control panel sends a gear adjustment command corresponding to the first ventilation gear control to the controller 4. After receiving the gear adjustment command, the controller 4 determines the target rotation angle based on the angle of the output shaft of the motor 31 when the door 2 is in the third stop position and the angle of the output shaft of the motor 31 when the door 2 is in the second stop position. It then controls the output shaft of the motor 31 to rotate by the target rotation angle, thereby switching the door 2 from the third stop position to the second stop position under the swinging action of the first link 32. It is easy to understand that the target rotation angles determined by the controller 4 in the above process are necessarily different because the swinging direction of the first link 32 is different. Accordingly, one of the two target rotation angles determined in the two gear adjustment processes is a positive angle, and the other is a negative angle.

[0047] The execution process between the control panel, controller 4, and motor 31 for the user to select or press other gear controls can be referred to the above text, and will not be repeated here.

[0048] Furthermore, this embodiment does not limit the specific value of the rotation angle required for the output shaft of the motor 31 when the door 2 switches between multiple stopping positions.

[0049] In some possible embodiments, the control panel has a knob that can determine a target rotation angle based on a first dwell angle of the knob and a second dwell angle of the output shaft of the motor 31, and control the output shaft of the motor 31 to rotate by the target rotation angle so that the door 2 stops at a position corresponding to the angle of the knob. In some examples, the rotation range of the knob can be 360°, and for the door 2, the rotation range of the motor 31 from the fully closed position to the fully open position can be 180°. It is easy to understand that the motor 31 can stop at any angle when the knob stops. In this way, the user can achieve stepless adjustment by rotating the knob and controlling the dwell angle of the output shaft of the motor 31 through the controller 4, so that the door 2 blocks at least part of the air inlet 111 and / or the air outlet 112.

[0050] In some possible embodiments, the bathroom heater panel also includes a position detection component 5.

[0051] like Figure 10 As shown, the position detection component 5 includes multiple Hall sensors 51 and a permanent magnet 52. The multiple Hall sensors 51 are located on the same side of the mask 1 in the thickness direction, and are spaced apart along a first direction X. Each Hall sensor 51 is connected to the mask 1. The permanent magnet 52 is connected to the door 2.

[0052] For example, the position detection component 5 includes four Hall sensors 51, which are equally spaced apart. The motor 31 is a stepper motor.

[0053] Multiple Hall sensors 51 are electrically connected to controller 4. Controller 4 is also used to: determine the actual rotation angle of motor 31 based on the magnetic field distribution information detected by the multiple Hall sensors 51; determine the correction rotation angle based on the actual rotation angle and the target rotation angle; and control the output shaft of motor 31 to rotate to correct the rotation angle.

[0054] In implementation, the controller 4 pre-stores a first target magnetic field strength value, a second target magnetic field strength value, a third target magnetic field strength value, a fourth target magnetic field strength value, a fifth target magnetic field strength value, a sixth target magnetic field strength value, and a seventh target magnetic field strength value. These seven target magnetic field strength values ​​are the target magnetic field strength values ​​emitted by the permanent magnet 52 detected by multiple Hall sensors 51 when the door 2 is in the fully closed position, the second stop position, the third stop position, the fifth stop position, the first stop position, the fourth stop position, and the fully open position, respectively. It should be noted that the first to seventh target magnetic field strength values ​​are not limited to single values; they can be combinations of multiple values, with each value in the combination corresponding to a magnetic field strength value emitted by the permanent magnet 52 detected by multiple Hall sensors 51. Furthermore, after the controller 4 determines the target rotation angle based on the gear adjustment command and controls the output shaft of the motor 31 to rotate to the target rotation angle, the controller 4 receives real-time magnetic field strength values ​​sent by multiple Hall sensors 51, then determines the actual rotation angle based on the real-time magnetic field strength values, determines the difference between the actual rotation angle and the target rotation angle, and determines this difference as the correction rotation angle. Finally, the controller 4 controls the output shaft of the motor 31 to rotate to the correction rotation angle.

[0055] During the use of the bathroom heater, as the usage time of the motor 31 increases, some of the internal teeth of the motor 31 may be worn flat or fall off, resulting in a deviation between the actual rotation angle of the output shaft of the motor 31 and the target rotation angle determined by the controller 4.

[0056] Using the technical solution provided in this embodiment, for a bathroom heater using this panel, the controller 4 can determine the difference between the actual rotation angle and the target rotation angle of the motor 31 through the position detection component 5, and determine the difference as the correction rotation angle. The controller 4 controls the output shaft of the motor 31 to rotate the correction rotation angle, so that the final position of the door 2 is closer to the position corresponding to the user-selected gear, thereby improving the accuracy of the door 2's hovering position relative to the air inlet 111 and / or air outlet 112.

[0057] In some examples, multiple Hall sensors 51 are bonded to the mask 1, and a permanent magnet 52 is bonded to the door 2. This ensures that the relative positions of the multiple Hall sensors 51 with respect to the mask 1 and the relative positions of the permanent magnet 52 with respect to the door 2 remain unchanged, thereby improving the accuracy of the actual magnetic field strength detected by the multiple Hall sensors 51.

[0058] In some examples, such as Figure 10 As shown, multiple Hall sensors 51 are located on the side of the mask 1 facing away from the door 2, that is, on the side of the mask 1 facing away from the ground. The permanent magnet 52 is located on the side of the door 2 closest to the mask 1, that is, on the side of the door facing away from the ground. In this way, the door 2 can support the permanent magnet 52, and the mask 1 can support the multiple Hall sensors 51, thereby reducing the possibility of the Hall sensors 51 and the permanent magnet 52 falling from the bathroom heater panel and improving safety.

[0059] In some examples, such as Figure 10 and Figure 12 ( Figure 12 for Figure 11 As shown in the enlarged view, the mask 1 has a receiving groove 13 on the side wall near the door 2. When the door 2 and the mask 1 are in contact, the permanent magnet 52 is located in the receiving groove 13. In this way, the receiving groove 13 can provide installation space for the permanent magnet 52, so that the door 2 can fit tightly with the mask 1 when it is in the fully closed position.

[0060] In some possible embodiments, the mask 1 includes a mask body 101 and a mounting base 102.

[0061] like Figure 13 and Figure 14 ( Figure 14 for Figure 13 (A partially enlarged view), the mask body 101 has a ventilation opening 11 and an air-proof opening 12, wherein the ventilation opening 11 includes the air inlet 111 and the air outlet 112 mentioned above. The air inlet 111 and the air outlet 112 may or may not be connected, and this disclosure does not limit this. Further, see Figure 13The bathroom heater panel includes two drive assemblies 3. Correspondingly, the face shield 1 includes two mounting bases 102. The face shield body 101 has two clearance openings 12, which are respectively connected to the two sides of the ventilation opening 11 along its length. The clearance openings 12 can be rectangular, and the size of the clearance openings 12 is larger than the size of the first connecting rod 32, thereby ensuring that at least a portion of the first connecting rod 32 can pass through the clearance openings 12. The mounting base 102 has a block structure with a Z-shaped cross-section. The two bottoms of the mounting base 102 are respectively connected to the two opposite edges of the clearance openings 12. Exemplarily, the mounting base 102 and the face shield body 101 can be connected by bolts. The first connecting rod 32 is located in the clearance area of ​​the mounting base 102, and one end of the first connecting rod 32 is rotatably connected to the mounting base 102. The other end of the first connecting rod 32 passes through the clearance opening 12 and is rotatably connected to the door 2 (not shown in the figure).

[0062] In some examples, such as Figure 15 As shown, the drive assembly 3 also includes a second link 33. The second link 33 has the same structure as the first link 32, and the second link 33 is arranged parallel to the first link 32. The second link 33 is located in the clearance area of ​​the mounting base 102, and one end of the second link 33 is rotatably connected to the mounting base 102, while the other end of the second link 33 passes through the clearance opening 12 and is rotatably connected to the door body 2 (not shown in the figure). In implementation, the first link 32 is connected to the output shaft of the motor 31 and is the driving link, while the second link 33 is not directly connected to the motor 31 and is the driven link.

[0063] Specifically, see Figure 14 and Figure 15 The mounting base 102 includes a first part 1021 and a second part 1022, which are respectively connected to the mask body 101 by bolts. Figure 15 As shown, one end of the first connecting rod 32 has a first columnar boss 321, and one end of the second connecting rod 33 has a second columnar boss 331. The first columnar boss 321 and the second columnar boss 331 are rotatably connected to the mounting base 102, respectively. This improves the rotational stability between the first connecting rod 32, the second connecting rod 33, and the mounting base 102.

[0064] Further, see Figure 15The first connecting rod 32 includes a first rod portion and a first columnar boss 321, with both ends of the first columnar boss 321 protruding from the first rod portion. The second connecting rod 33 includes a second rod portion and a second columnar boss 331, with both ends of the second columnar boss 331 protruding from the second rod portion. The first extension of the first part 1021 is provided with a first mounting hole and a second mounting hole, and the second extension of the second part 1022 is provided with a third mounting hole and a fourth mounting hole. The first mounting hole and the third mounting hole are both circular through holes and are coaxially arranged, respectively used to accommodate the two ends of the first columnar boss 321. The second mounting hole and the fourth mounting hole are both circular through holes and are coaxially arranged, respectively used to accommodate the two ends of the second columnar boss 331. This further improves the rotational stability between the first connecting rod 32 and the second connecting rod 33 and the mounting base 102.

[0065] See in some examples Figure 15 The first link 32 has a third columnar boss 322 at one end, and the second link 33 has a fourth columnar boss 332 at the other end. The third columnar boss 322 and the fourth columnar boss 332 are rotatably connected to the door body 2 (not shown in the figure). This improves the rotational stability between the first link 32, the second link 33 and the door body 2.

[0066] In some examples, the plane formed by the first rotation axis 320 of the first link 32 and the second rotation axis 330 of the second link 33 is parallel to the mask body 101. This ensures that the door 2 remains parallel to the mask body 101 as it moves between multiple stopping positions.

[0067] The technical solutions provided in this disclosure have at least the following beneficial effects: This disclosure provides a bathroom heater panel. For a bathroom heater using this panel, the air outlet 112 of the cover 1 is connected to the air outlet of the air supply device. The controller 4 can control the output shaft of the motor 31 to rotate by a target rotation angle, so that the door 2 moves between a fully open position, a fully closed position, and a first stop position. When the door 2 is in the first stop position, the door 2 can partially block the air outlet 112, thereby partially blocking the warm airflow output by the air supply device, thereby reducing the amount of air reaching the user's location and improving the adjustable range of the bathroom heater's air supply volume.

[0068] This disclosure also provides a bathroom heater, which includes an air supply device, a control panel, and the aforementioned bathroom heater panel. The air supply device is connected to the air outlet 112. The control panel has multiple speed control buttons and is communicatively connected to a controller 4. The control panel is used to: determine a target speed in response to a selection operation of the target speed control button, and send a speed adjustment command corresponding to the target speed to the controller 4.

[0069] For details on the connection between the control panel and controller 4, as well as the command transmission and reception process, please refer to the above text; it will not be repeated here.

[0070] In some possible embodiments, the bathroom heater also includes a ventilation device, and the mask 1 also includes an air inlet 111, with the ventilation device connected to the air inlet 111. The controller 4 is electrically connected to the motor of the ventilation device and the motor of the air supply device, respectively. The controller 4 is also used to: determine the gear adjustment command to control the corresponding target speed from a pre-stored correspondence between target gear, target rotation angle and target speed, and control the motor of the ventilation device or the motor of the air supply device to run at the target speed.

[0071] In implementation, controller 4 has a pre-stored table showing the correspondence between target gear and target speed, as shown in the table below: Table 1

[0072] The target speed includes seven speeds, numbered one through seven. These seven speeds correspond one-to-one with the speeds triggered by the first ventilation speed control, second ventilation speed control, third ventilation speed control, first heating speed control, second heating speed control, third heating speed control, and the off control mentioned above. The first target speed includes seven speeds: A, B, and C. In some examples, speeds A, B, and C correspond to 50%, 75%, and 100% of the ventilation equipment's maximum speed, respectively; speeds D, E, and F correspond to 100% of the ventilation equipment's maximum speed; and speed G is the speed at which the ventilation equipment is stopped. In some examples, speeds O, P, Q, and U correspond to the speed at which the air supply equipment is stopped, and speeds R, S, and T correspond to 50%, 75%, and 100% of the ventilation equipment's maximum speed, respectively.

[0073] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the principles of this disclosure should be included within the protection scope of this disclosure.
