Description

Technical Field

[0002] Air conditioners in related technologies have a display screen on the panel, with buttons or touch areas for operation. However, this method of operation is rigid and monotonous and needs improvement. Furthermore, in related technologies, household appliances with knobs always have the knobs protruding from the appliance's surface, making the appliances still appear uninspired. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a panel component, which includes a knob. The knob is operable, enhancing the user experience. Furthermore, the knob is retractable, improving the flexibility of the panel component. By setting a knob device and guiding it in conjunction with the panel assembly, the knob can stably extend and retract relative to the panel, ensuring smooth movement and preventing shaking or jamming.

[0074] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0075] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0076] Hereinafter, with reference to the accompanying drawings, a panel component 1000 according to a first aspect embodiment of the present invention will be described.

[0077] Combination Figures 1-4 The panel component 1000 includes a panel assembly 100 and a knob device 200. The panel assembly 100 includes a panel 101 with a clearance hole 11. The knob device 200 includes a knob 201, which is disposed opposite to the clearance hole 11 and is movable relative to the panel 101, extending outward and retracting inward relative to the panel 101 by repeatedly passing through the clearance hole 11.

[0078] Among them, panel component 1000 is an exterior component used to cover and protect the internal structure of household appliances or related equipment. Panel component 1000 has a wide range of applications, such as household appliances. Panel 101 is the panel of a household appliance. The type of household appliance is not limited, such as air conditioner 10000, washing machine, refrigerator, microwave oven, rice cooker, water heater, gas stove, water purifier, electric fan, etc.

[0079] The panel 101 has a clearance hole 11. The configuration of the panel 101 is not limited. For example, it can be a single panel, or it can include a front panel and a panel support. The front panel is mounted on the front side of the panel support. The clearance hole 11 is formed on the front panel. The panel support can form a groove or a cutout at the corresponding clearance hole. The form of the clearance hole 11 is not limited. For example, it can be a through hole that passes through the panel 101 (such as the front panel); or the panel 101 (such as the front panel) has a rearward recessed portion that defines a front-opening groove. The front opening of the groove constitutes the clearance hole 11.

[0080] For example, the clearance hole 11 can be a through hole that passes through the panel 101, thereby facilitating the installation of the knob 201. For example, in conjunction with the structural design, the knob 201 can be installed at the clearance hole 11 along the direction from the inside to the outside of the panel 101; or, in conjunction with the structural design, the knob 201 can be installed at the clearance hole 11 along the direction from the outside to the inside of the panel 101.

[0081] The knob 201 is positioned opposite the clearance hole 11. The knob 201 is movable relative to the panel 101, repeatedly extending outward and retracting relative to the panel 101 through the clearance hole 11. Specifically, the knob 201 moves towards the outer side of the panel 101 (extension movement) and moves towards the inner side of the panel 101 (retraction movement). More specifically, "extension" means that the knob 201 moves from the inner side of the panel 101 to the outer side of the panel 101 through the clearance hole 11, allowing the knob 201 to protrude more from the outer side of the panel 101; "retraction" means that the knob 201 moves from the outer side of the panel 101 to the inner side of the panel 101 through the clearance hole 11, allowing the knob 201 to retract more into the inner side of the panel 101. In this paragraph, "outer" refers to the outer side of panel 101, that is, the side of panel 101 facing the user, and the opposite side is "inner", that is, the inner side of panel 101, that is, the side of panel 101 facing away from the user.

[0082] Alternatively, "retracting" refers to the movement of knob 201 towards the inside of panel 101, that is, the outer end face of knob 201 moves towards the direction closer to panel 101. "Extending" refers to the movement of knob 201 towards the outside of panel 101, that is, the outer end face of knob 201 moves away from panel 101. The final position of knob 201 retracting relative to panel 101 can be that the outer end face of knob 201 is flush with the outer surface of panel 100, or that the outer end face of knob 201 is recessed into the outer surface of panel 101, or that the outer end face of knob 201 protrudes from the outer surface of panel 101, but the protrusion height is less than the protrusion height of knob 201 in the final position of extending relative to panel 101. Here, "outer end face of knob 201" refers to the side surface of knob 201 away from the inside of panel 101, that is, the side surface of knob 201 facing the user. "Outer surface of panel 101" refers to the outer surface of panel 101. "Protrusion height" refers to the distance between the outer end face of the knob 201 and the outer surface of the panel 101 along the extension and retraction direction of the knob 201.

[0083] The driving force for moving the knob 201 is not limited. For example, an actuator 202 can be provided. The actuator 202 can be electric, pneumatic, hydraulic, etc. The actuator 202 can be provided on the panel assembly 100 and drive the knob 201 in a transmission cooperation to drive the knob 201 to extend or retract. Alternatively, the actuator 202 can also be provided on the knob 201 and drive the knob 201 in a transmission cooperation with the panel assembly 100 to drive the knob 201 to extend or retract. The purpose of "transmission cooperation" is to transmit power through mechanical cooperation. The specific method is not limited, such as gear transmission, belt transmission, chain transmission, screw transmission, etc.

[0084] Of course, the knob 201 can also be extended or retracted by a drive device other than the panel component 1000. It is worth noting that a drive device can also be omitted, and the knob can be operated manually by the user. For example, a groove for accommodating fingers can be provided on the circumference of the clearance hole 11. The user can insert their fingers into the groove to lift the knob 201 so that the knob 201 extends outward relative to the panel 101. Similarly, the user can also push the knob 201 back so that the knob 201 retracts inward relative to the panel 101.

[0085] The adjustment functions of knob 201 are unlimited. For example, users can rotate knob 201 to select functions of air conditioner 10000 (such as cooling, heating, dehumidification, fresh air, etc.), set values ​​of air conditioner 10000 (temperature, fan speed, air direction, etc.), turn air conditioner 10000 on and off, or link with other functions of air conditioner 10000 (such as display, voice, lighting, etc.), or link with network-connected home appliances throughout the house. In addition, knob 201 can also be equipped with a touch screen and / or floating parts, allowing adjustment of the knob through touch and / or pressing.

[0086] The panel assembly 100 includes a first guide structure 7121a disposed on the inner side of the panel 101, and the knob device 200 includes a second guide structure 3121a. The second guide structure 3121a guides and cooperates with the first guide structure 7121a to constrain the knob 201 to move linearly relative to the panel 101. The forms of the second guide structure 3121a and the first guide structure 7121a are not limited. For example, the first guide structure 7121a is a groove, and the second guide structure 3121a is a slider. The slider slides within the groove, enabling the knob 201 to move linearly. Alternatively, the first guide structure 7121a can be a guide post, and the second guide structure 3121a can be a guide hole. The guide post is inserted into the guide hole, and the knob 201 extends and retracts along the direction of the guide post. Of course, the first guide structure 7121a can include multiple sets of sliders and grooves, or multiple sets of guide posts and guide holes, to make the extension and retraction of the knob 201 relative to the panel 101 more stable.

[0087] The knob 201 can extend outward and retract relative to the panel 101 through the clearance hole 11 on the panel 101. When the user needs to operate the knob 201, such as adjusting device parameters or switching function modes, the knob 201 can be extended outward and protrude from the surface of the panel 101 so that the user can easily rotate it, or perform operations such as rotation combined with touch or press. When the knob 201 is not needed, the knob 201 can be retracted to reduce the outward protrusion of the knob 201, which saves space and can also prevent the knob 201 from being accidentally bumped to a certain extent.

[0088] However, if the knob 201 shakes during its extension and retraction, the shaking may cause abnormal friction between the knob 201 and the edge of the clearance hole 11, resulting in the knob 201 getting stuck during extension and retraction. In severe cases, the shaking may also cause the knob 201 to deviate from its normal movement trajectory, resulting in it not aligning with the clearance hole 11 and eventually getting stuck at the clearance hole 11 and unable to move normally.

[0089] In the technical solution of this application, the guiding cooperation of the first guide structure 7121a and the second guide structure 3121a effectively constrains the knob 201 to move in a straight line relative to the panel 101. This improves the situation where the knob 201 wobbles or deviates during its reciprocating extension and retraction through the clearance hole 11, ensuring that the knob 201 can move accurately and smoothly, and improving the stability and reliability of the knob 201 operation. In addition, the guiding cooperation prevents abnormal friction between the knob 201 and the edge of the clearance hole 11 during movement, reducing problems such as jamming and wear caused by friction, and extending the service life of the knob 201 and the panel 101. Because the knob 201 can move stably and smoothly, the user will find the knob 201 more stable when operating it, without any wobbling, thereby improving the accuracy of the user's operation of the knob 201.

[0090] Combination Figures 1-4 In some embodiments, the first guide structure 7121a includes a first rod 7121, and the second guide structure 3121a includes a second rod 3121. One of the first rod 7121 and the second rod 3121 is sleeved on the outside of the other to form an inner and outer guide fit.

[0091] In the above technical solution, the inner and outer guide fit structure formed by the first rod 7121 and the second rod 3121 provides a stable guide for the knob 201. The guide fit restricts the degree of freedom of the knob 201 in the direction perpendicular to the direction of movement (i.e., the direction of extension and retraction of the knob 201), so that the knob 201 can only move along a predetermined straight line, thereby reducing the wobbling phenomenon that may occur during the extension and retraction of the knob 201, ensuring that the extension and retraction action of the knob 201 is smooth and stable, avoiding problems such as jamming or sticking caused by wobbling, and improving the reliability and stability of the operation of the knob 201.

[0092] In addition, when the user rotates the knob 201, the inner and outer guide structure can still function, which limits the radial wobble of the knob 201 during rotation and improves the user's operating feel.

[0093] Furthermore, the guide engagement is achieved by using an inner and outer sleeve structure of the first rod 7121 and the second rod 3121. The structure is relatively simple, the design is less difficult, and it can withstand greater external forces without easily deforming or being damaged, thus extending the service life of the equipment.

[0094] In the embodiments of this application, one of the first rod 7121 and the second rod 3121 is sleeved on the outside of the other. It can be that the first rod 7121 is sleeved on the outside of the second rod 3121, or the second rod 3121 is sleeved on the outside of the first rod 7121. The cross-sectional shape of the first rod 7121 and the second rod 3121 perpendicular to the outward and inward directions of the knob 201 is not limited. For example, the first rod 7121 and the second rod 3121 can be cylindrical rods, square rods, polygonal rods, etc.

[0095] It is worth noting that the type of knob according to the embodiments of this application is not limited. It can be an encoder knob (incremental encoder), a capacitive touch knob, or a magnetoelectric knob, etc. Among them, the encoder knob (incremental encoder) contains an encoder. The encoder converts information such as the position and speed of mechanical motion into digital signals (pulses or codes) that can be recognized by the controller through photoelectric, electromagnetic, capacitive sensing methods, so as to realize accurate measurement and feedback of motion state. For example, when the knob is rotated, the code disk of the encoder rotates accordingly. Light is alternately blocked by the stripes of the code disk. The photosensitive sensor receives the intermittent light signal and converts it into an electrical pulse signal. The circuit calculates the rotation angle and direction of the knob according to the number and direction of the pulses (forward / reverse rotation) and outputs a digital signal to the device processor to realize adjustment. The surface of the capacitive touch knob is made of capacitive sensing material and integrates a capacitive sensor. When the finger rotates, the capacitance value between the finger and the knob surface changes. The sensor detects the frequency and direction of the capacitance change and converts it into an electrical signal. The chip interprets it as a rotation action to realize adjustment. The magnetoelectric knob has a permanent magnet installed inside and a Hall sensor arranged around it. When the knob is rotated, the direction of the magnetic field of the permanent magnet changes. The Hall sensor detects the change in magnetic field, generates a corresponding electrical signal, and transmits it to the processor to achieve adjustment.

[0096] Combination Figure 2 , Figure 3 and Figure 4 In some embodiments, the knob 201 includes an encoder 21, which includes an encoder rotating part 21a and an encoder fixing part 21b. The encoder rotating part 21a is rotatable relative to the encoder fixing part 21b. The panel assembly 100 includes a base 71, which is disposed inside the panel 101 and fixed relative to the panel 101. The base 71 is an integral structural component and includes a mating section 712b. The mating section 712b includes a first rod 7121 and a rotation limiting structure 7122. A second rod 3121 extends into the first rod 7121, and the rotation limiting structure 7122 is located outside the first rod 7121 and engages with the encoder fixing part 21b for rotation limiting.

[0097] In the above technical solution, the base 71 is an integrated structural component. The mating section 712b of the base 71 includes a first rod 7121 and a rotation limiting structure 7122. The second rod 3121 extends into the first rod 7121 to form an inner and outer guide fit, so that the knob 201 can move linearly relative to the panel 101. The rotation limiting structure 7122 fits with the encoder fixing part 21b to limit rotation, so that the knob 201 does not rotate during linear movement relative to the panel 101. Thus, the base 71 integrates both the inner and outer guide fit function and the rotation limiting fit function, and is an integrated structural component. That is, the first rod 7121 and the rotation limiting structure 7122 of the mating section 712b are manufactured by a one-time molding process, such as injection molding or die casting, rather than being assembled from multiple parts. This reduces the number of parts, lowers the assembly difficulty and cost, and improves the overall strength and stability of the base 71. The integrated structure can better withstand external forces, such as the guiding force and the rotation limiting force, thereby enhancing the reliability of the guiding and rotation limiting forces and improving the reliability and stability of the knob 201's movement.

[0098] Furthermore, since the rotation limiting structure 7122 directly engages with the encoder fixing part 21b, the encoder fixing part 21b is reliably restricted from rotating. This allows the user to precisely control the rotation of the encoder rotating part 21a when turning the knob 201, improving the accuracy of inputting commands to the knob 201 by turning it and avoiding command input deviations caused by the rotation of the encoder rotating part 21a.

[0099] In the embodiments of this application, the specific form of the rotation limiting structure 7122 and the encoder fixing part 21b in rotation limiting cooperation is not limited. For example, a keyway can be provided on the encoder fixing part 21b, and the rotation limiting structure 7122 can be constructed as a key. The key slides in the keyway, thereby limiting the rotation of the encoder fixing part 21b. For example, a rotation limiting sleeve can also be provided on the encoder fixing part 21b, and the rotation limiting structure 7122 can be constructed as a rotation limiting post. The shape of the rotation limiting sleeve limits the rotation of the encoder fixing part 21b.

[0100] Combination Figure 8 and Figure 9 In some embodiments, the knob 201 includes a knob support 31, which is an integrated structural component and includes a connecting section 312. The connecting section 312 includes a second rod 3121 and a first buckle 3122. The first buckle 3122 is located outside the first rod 7121 and is engaged and fixed with the encoder fixing part 21b.

[0101] In the above technical solution, the knob bracket 31 is an integrated structural component and includes a connecting section 312. The connecting section 312 includes a second rod 3121 and a first buckle 3122. The second rod 3121 extends into the first rod 7121 to form an inner and outer guide fit, so that the knob bracket 31 can move linearly relative to the panel 101. The first buckle 3122 is engaged and fixed with the encoder fixing part 21b, so that the knob bracket 31 drives the encoder 21 to move linearly together. Thus, the knob bracket 31 integrates both the inner and outer guide fit function and the function of driving the encoder 21 of the knob 201 to move together as a whole. Moreover, it is an integrated structural component, that is, the second rod 3121 and the first buckle 3122 of the connecting section 312 are manufactured by a one-time molding process, such as injection molding or die casting, rather than being assembled from multiple parts. This reduces the number of parts, lowers the assembly difficulty and cost, and improves the overall strength and stability of the knob bracket 31. The integrated structure can better withstand external forces, such as the force of the guide and the force that drives the encoder 21 to move together. The overall structure of the knob 201 is more stable and reliable, ensuring the reliability of the knob 201's movement when the knob 201 is frequently raised and lowered.

[0102] Furthermore, the first snap-fit ​​3122 on the connecting section 312 is snapped into and fixed to the encoder fixing part 21b. Compared with bolt connections, welding, and other connection methods, this allows for quick and accurate connection of the knob bracket 31 and the encoder fixing part 21b during production and assembly, improving production efficiency. The first snap-fit ​​3122 is located outside the first rod 7121, making reasonable use of space. While fulfilling the connection function, it will not interfere with the installation and movement of other internal components of the knob 201. This makes the entire knob 201 structure more compact, which is beneficial for the miniaturization design of the knob 201.

[0103] Combination Figure 4 , Figures 7-9In some embodiments, the encoder rotating part 21a is an outer ring 211, and the encoder fixing part 21b is an inner ring 212. The outer ring 211 is sleeved on the outside of the inner ring 212, and the mating section 712b and the connecting section 312 both extend into the inner ring 212. A plurality of retaining ribs 2122 are formed on the inner peripheral wall of the inner ring 212, which are spaced apart in the circumferential direction. There are multiple first buckles 3122 that are spaced around the first rod 7121. The multiple first buckles 3122 are engaged with the multiple retaining ribs 2122 in a one-to-one manner, and the adjacent first buckles 3122 are separated by a clearance. The inner peripheral wall of the inner ring 212 has multiple limiting grooves 2121 arranged at intervals along the circumference. The multiple limiting grooves 2121 and multiple retaining ribs 2122 are arranged alternately. The rotation limiting structure 7122 is formed as a protrusion on the outer peripheral wall of the first rod 7121. There are multiple rotation limiting structures 7122 arranged at intervals along the circumference of the first rod 7121. The multiple rotation limiting structures 7122 are located in the multiple clearance areas 312a respectively. The multiple rotation limiting structures 7122 and the multiple limiting grooves 2121 are matched one by one to limit rotation.

[0104] In the above technical solution, the connecting section 312 of the knob bracket 31 extends into the inner ring 212 and is fixed by the first buckle 3122 to the retaining rib 2122 formed on the inner peripheral wall of the inner ring 212. The snap-fit ​​method is simple to operate and improves the installation efficiency of the knob bracket 31 and the inner ring 212. Meanwhile, multiple first buckles 3122 and multiple retaining ribs 2122 are engaged in a one-to-one manner, which enhances the stability of the connection between the knob bracket 31 and the inner ring 212. An avoidance area 312a is defined between adjacent first buckles 3122, and multiple rotation limiting structures 7122 are located in the multiple avoidance areas 312a in a one-to-one manner. That is, multiple avoidance areas 312a avoid multiple rotation limiting structures 7122 in a one-to-one manner. The rotation limiting structure 7122 needs to cooperate with the limiting groove 2121 of the inner ring 212, which realizes the rotation limiting cooperation between the knob bracket 31 and the inner ring 212. While ensuring that the knob bracket 31 can be easily connected to the encoder 21, it does not affect the rotation limiting function of the rotation limiting structure 7122. Therefore, the inner ring 212 structure of the encoder 21 is relatively compact, which is conducive to the miniaturization of the knob 201.

[0105] In the above technical solution, multiple rotation limiting structures 7122 and multiple limiting grooves 2121 are inserted and fitted one by one along the axial direction. That is, the rotation limiting structures 7122 and the limiting grooves 2121 are connected at multiple points, which increases the stability and reliability of rotation limiting. Compared with single-point or a few-point fit, multi-point fit can better disperse the force and reduce the risk of loose fit or damage to the inner ring 212 due to excessive local force. In addition, the multi-point fit can restrict the inner ring 212 from multiple directions, effectively limiting the rotation of the encoder fixing part 21b. The relative rotational motion between the encoder rotating part 21a and the encoder fixing part 21b can accurately reflect the angle of the knob 201 rotated by the user. Thus, the encoder 21 can accurately measure the rotation angle and position change of the encoder rotating part 21a relative to the encoder fixing part 21b, thereby providing accurate control signals for the equipment controlled by the knob 201 and improving the control accuracy and performance of the knob 201.

[0106] In some embodiments, the first rod 7121 is a hollow rod with a cylindrical hole of uniform cross-section inside, and the outer peripheral surface of the second rod 3121 is formed as a cylindrical surface of uniform cross-section. The first rod 7121 is sleeved on the outside of the second rod 3121, and the cylindrical hole and the cylindrical surface are fitted with a fitting gap of 0.05mm-0.1mm. The cylindrical hole of uniform cross-section means that the cross-sectional shape and area remain unchanged along the axial direction of the first rod 7121, and the cylindrical surface of uniform cross-section means that the cross-sectional shape and area remain unchanged along the axial direction of the second rod 3121.

[0107] In the above technical solution, the first rod 7121 is a hollow rod with a cylindrical hole of uniform cross-section inside, and the outer circumferential surface of the second rod 3121 is a cylindrical surface of uniform cross-section. The two are fitted together and guided, so the second rod 3121 and the first rod 7121 are tightly fitted together and guided in the axial direction of the first rod 7121, providing a stable guiding effect for the knob 201. Thus, during the movement of the knob 201, it can prevent the knob 201 from deviating or shaking, and improve the accuracy and reliability of the movement of the knob 201.

[0108] In the above technical solution, the clearance is controlled within the range of 0.05mm-0.1mm. This ensures that the second rod 3121 can slide or rotate smoothly within the first rod 7121 without causing loosening due to excessive clearance, which would affect the reliability of the knob 201's movement. Simultaneously, it reduces friction between the first rod 7121 and the second rod 3121. If the clearance is too small, the two rods will generate significant friction during relative movement, accelerating the wear of both rods. Controlling the clearance within 0.05mm-0.1mm ensures smooth movement while keeping friction within a reasonable range, reducing wear rate and extending the service life of both rods.

[0109] In some embodiments, the hole is a cylindrical hole and the cylindrical surface is a cylindrical surface. This results in a simple structure, easy processing, and easy assembly, requiring no attention to orientation. Furthermore, when the second rod 3121 and the first rod 7121 are guided and fitted together, the second rod 3121 can rotate relative to the first rod 7121 by a certain angle. This facilitates alignment with other structures. For example, the clearance area 312a defined between the first latches 3122 can be adjusted to correspond one-to-one with the rotation-limiting structure 7122 of the mating section 712b of the base 71, thereby allowing both the knob bracket 31 and the base 71 to smoothly engage with the inner ring 212 of the encoder 21 (the knob bracket 31 engages with the inner ring 212, and the base 71 engages with the inner ring 212), thus improving the ease of assembly of the knob 201.

[0110] Combination Figures 1-4 In some embodiments, the knob device 200 further includes a driver 202 for driving the knob 201 to reciprocate in a straight line.

[0111] Therefore, the knob 201, driven by the driver 202, can reciprocate through the clearance hole 11, moving back and forth between an extended position and a retracted position, thus achieving extension and retraction relative to the panel 101. When the knob 201 is needed, it extends out of the panel 101 for easy user operation; when not in use, it retracts into the panel 101, saving space and avoiding potential problems such as bumps, dust accumulation, and accidental touches that might occur if the knob 201 protrudes from the surface of the panel 101, thereby improving the user experience. Furthermore, since the driver 202 can drive the knob 201 to reciprocate through the clearance hole 11, the user does not need to manually operate the extension and retraction of the knob 201. For example, the driver 202 can be triggered to operate through other control methods of the knob 201 (such as touchscreen buttons, physical buttons, voice commands, etc.), achieving automatic movement of the knob 201.

[0112] Combination Figures 1-4 In some embodiments, the driver 202 is disposed on the panel assembly 100 and is driven to engage with the knob 201 to drive the knob 201 to reciprocate in a straight line relative to the driver 202.

[0113] In the above technical solution, by setting the driver 202 on the panel assembly 100, for example, it can be directly set on the panel 101, or it can be set on other components connected to the panel 101 (such as the panel base 102 mentioned below). Thus, the driver 202 is closer to the knob 201, facilitating direct driving of the knob 201. This makes the structure of the entire panel assembly 1000 more compact, achieving integrated component arrangement, reducing space occupation, and promoting the miniaturization of the knob 201. It also facilitates equipment installation and maintenance. Driving the knob 201 with the driver 202 reduces positional deviations caused by human factors compared to manual operation. For example, the stable power output of the driver 202 enables the knob 201 to remain stable during movement, avoiding the shaking and jamming that may occur during manual operation, and improving the stability of the knob 201's movement.

[0114] See Figure 4 In some embodiments, the knob 201 includes a second rod 3121 with a threaded hole 31211 inside. The driver 202 includes a motor 61 and a drive shaft 62. The drive shaft 62 extends into the second rod 3121 and is a screw 62a that meshes with the threaded hole 31211. The motor 61 is used to drive the drive shaft 62 to rotate. The panel assembly 100 is engaged with the knob 201 to limit rotation and prevent the second rod 3121 from rotating relative to the panel 101.

[0115] In the above technical solution, the driver 202 is directly connected to the second rod 3121 of the knob 201, and the motor 61 achieves transmission by meshing the drive shaft 62 with the threaded hole 31211 in the second rod 3121. No additional transmission mechanism (such as gear transmission, belt transmission, etc.) is required, which simplifies the structure, reduces the number of parts and the space occupied. The transmission structure is relatively simple and compact, and occupies little space.

[0116] The meshing transmission between the screw 62a and the threaded hole 31211 provides high transmission accuracy and stability. When the motor 61 drives the drive shaft 62 (screw 62a) to rotate, the rotation-limiting engagement between the structural components and the knob 201 prevents the second rod 3121 from rotating relative to the first rod 7121. The second rod 3121 can only move linearly along the axis of the first rod 7121, thereby driving the knob 201 to move linearly, reducing the problem of knob 201 wobbling due to transmission errors. Simultaneously, the threaded transmission has self-locking properties; when the motor 61 stops driving, the knob 201 remains in its current position and will not retract due to external forces, ensuring the stability of the knob 201's position.

[0117] See Figure 4In some embodiments, the first guide structure 7121a includes a first rod 7121, and the second guide structure 3121a includes a second rod 3121. The first rod 7121 is sleeved outside the second rod 3121 for guiding engagement with the second rod 3121. The first guide structure 7121a is disposed on the panel assembly 100, and the second guide structure 3121a is disposed on the knob device 200. The first rod 7121 being sleeved outside the second rod 3121, compared to the second rod 3121 being sleeved outside the first rod 7121, better restricts the radial wobble of the knob 201, avoiding problems such as wobbling or offset during movement, ensuring that the knob 201 can accurately and stably reach the predetermined position, and improving the reliability and accuracy of the knob 201 operation. Simultaneously, the structure of the first rod 7121 being sleeved outside the second rod 3121 for guiding engagement with the second rod 3121 is relatively simple, facilitating manufacturing, installation, and debugging.

[0118] Combination Figure 5 and Figure 6 In some embodiments, the panel assembly 100 includes a base 71, which is an integral structural component and includes a seat end plate 711 and a seat shaft 712. A knob 201 is located on the side of the seat end plate 711 facing the panel 101, and a motor 61 is located on the side of the seat end plate 711 away from the panel 101. The seat shaft 712 passes through the seat end plate 711. The portion of the seat shaft 712 on the side of the seat end plate 711 facing the panel 101 is a first rod 7121, and the portion of the seat shaft 712 on the side of the seat end plate 711 away from the panel 101 is a limiting ring 7123. A [missing information] is formed within the seat shaft 712. The positioning hole 712a extends along the axial direction. The motor 61 includes a motor body 612 and a limiting boss 611 protruding from the side of the motor body 612 facing the panel 101. The motor body 612 is located on the side of the base 71 away from the panel 101. The limiting boss 611 extends into the positioning hole 712a by the limiting ring 7123. The second rod 3121 extends into the positioning hole 712a from the first rod 7121. The limiting boss 611 and the second rod 3121 are both clearance-fitted with the positioning hole 712a. The drive shaft 62 is coaxially arranged with the motor 61 and extends into the second rod 3121 by the limiting boss 611.

[0119] In the above technical solution, the base 71 includes a seat end plate 711 and a seat shaft 712, and the base 71 is an integrated structural component. This enhances the reliability of the connection between the knob 201 and the motor 61 and the base 71. The portion of the seat shaft 712 located on the side of the seat end plate 711 facing the panel 101 is a first rod 7121, which cooperates with a second rod 3121 to achieve a guiding function. The portion of the seat shaft 712 located on the side of the seat end plate 711 away from the panel 101 is a limiting ring 7123, which cooperates with a limiting boss 611 of the motor 61 to achieve a limiting function. This reduces the number of parts and makes the overall structure more compact. A positioning hole 712a is formed in the seat shaft 712, and both the limiting boss 611 and the second rod 3121 are clearance-fitted with the positioning hole 712a, further saving space and making the entire knob 201 more compact.

[0120] In addition, the motor 61 includes a motor body 612 and a limiting boss 611 protruding from the side of the motor body 612 facing the panel 101. The limiting boss 611 extends into the positioning hole 712a through the limiting ring 7123 to position the motor 61. That is, at least a part of the motor body 612 protrudes from the limiting ring 7123, which is beneficial to the heat dissipation of the motor body 612 and reduces the transmission of vibration of the motor 61 to the base 71, thereby making the connection between the motor 61 and the base 71 more secure and reducing the possibility of loosening.

[0121] Furthermore, both the limiting boss 611 and the second rod 3121 mate with the positioning hole 712a, establishing a strict positioning relationship between the motor 61, the base 71, and the knob 201. The positioning hole 712a provides guidance and positioning for the limiting boss 611 and the second rod 3121, ensuring that the motor 61 is accurately positioned during installation and reducing the possibility of misalignment. Misalignment of the motor 61 can lead to uneven thread engagement between the drive shaft 62 and the second rod 3121. When the motor 61 drives the drive shaft 62 to rotate, problems such as excessive local force and increased friction may occur, thereby increasing the load on the motor 61 and making it prone to stalling. The engagement between the limiting boss 611 and the positioning hole 712a, as well as the engagement between the second rod 3121 and the positioning hole 712a, ensures that the drive shaft 62 of the motor 61 and the second rod 3121 have a high degree of coaxiality. This allows the drive shaft 62 and the threaded hole 31211 inside the second rod 3121 to mesh correctly, thereby enabling the motor 61 to transmit power smoothly during operation. This reduces the possibility of stalling caused by misalignment, and ensures that the knob 201 can extend and retract normally.

[0122] Combination Figure 5 and Figure 6In some embodiments, the fitting clearance G1 between the limiting boss 611 and the positioning hole 712a is 0.05mm-0.1mm, and the fitting clearance G2 between the second rod 3121 and the positioning hole 712a is 0.05mm-0.1mm. Therefore, the fitting clearances G1 and G2 are reasonably sized, ensuring high positioning accuracy of the limiting boss 611 and the second rod 3121 within the positioning hole 712a. When the motor 61 normally drives the knob 201, the smaller clearances reduce the wobbling and offset between transmission components, ensuring the accuracy and stability of power transmission, improving the precision of the knob 201's movement, and enabling the knob 201 to precisely extend and retract according to design requirements.

[0123] In addition, an appropriate clearance can prevent excessive friction between the limiting boss 611, the second rod 3121 and the positioning hole 712a due to overly tight fit, reduce wear between the second rod 3121 and the first rod 7121, reduce the risk of component damage, extend the service life of the components, and also reduce the impact of impurities such as metal shavings generated by wear on the performance of the transmission system.

[0124] Combination Figure 5 and Figure 6 In some embodiments, the end of the positioning hole 712a near the motor 61 forms a first chamfer 71231, and the outer periphery of the end of the second rod 3121 near the motor 61 forms a second chamfer 31212. During the installation of the motor 61, the limiting boss 611 needs to extend into the positioning hole 712a of the seat shaft 712 to cooperate with the limiting ring 7123. The first chamfer 71231 formed at the end of the positioning hole 712a near the motor 61 serves a guiding function. When the motor 61 is installed close to the base 71, the first chamfer 71231 can guide the limiting boss 611 to smoothly enter the positioning hole 712a, improving the installation efficiency of the motor 61; the second rod 3121 extends into the positioning hole 712a from the end of the first rod 7121 away from the limiting ring 7123. The second chamfer 31212 on the outer periphery of the end of the second rod 3121 close to the motor 61 also plays a guiding role. The second chamfer 31212 can make the second rod 3121 smoothly inserted into the positioning hole 712a, reducing the interference between the second rod 3121 and the entrance edge of the positioning hole 712a, making the installation process of the knob 201 smoother.

[0125] In the embodiments of this application, the shapes of the first chamfer 71231 and the second chamfer 31212 are not limited. For example, they can be rounded corners or inverted conical slopes. The size and angle of the chamfer should match the size and shape of the limiting boss 611 and the positioning hole 712a to ensure that the components can cooperate and move smoothly.

[0126] Combination Figure 7 and Figure 8In some embodiments, the knob 201 includes an encoder 21, a knob bracket 31, and a knob ring 41. The encoder 21 includes an encoder rotating part 21a and an encoder fixing part 21b. The encoder rotating part 21a is rotatable relative to the encoder fixing part 21b about a rotation axis. The driver 202 drives the knob 201 to move along the extension direction of the rotation axis. The knob ring 41 is fixedly connected to the encoder rotating part 21a. The knob bracket 31 is fixedly connected to the encoder fixing part 21b. The knob bracket 31 includes a second guide structure 3121a.

[0127] In the above technical solution, since the second rod 3121 participates in transmission and guidance and has a stable structure, and the second rod 3121 is part of the knob bracket 31, which is fixedly connected to the second part of the encoder 21, the second rod 3121 can serve as the support and positioning base for the encoder 21. When the user twists the knob ring 41, the torque can be transmitted to the second rod 3121. The second rod 3121 and the first rod 7121 form an inner and outer guide fit structure. The inner and outer fit restricts the radial wobble of the second rod 3121 during rotation. Thus, the second rod 3121 can effectively reduce the wobble of the knob ring 41 during twisting, allowing the user to operate the knob 201 accurately and smoothly, avoiding operational errors caused by wobble, and improving the accuracy and reliability of operation.

[0128] In the above technical solution, the encoder 21 is divided into an encoder rotating part 21a and an encoder fixed part 21b. The encoder rotating part 21a is rotatable relative to the encoder fixed part 21b. The knob ring 41 surrounds the outer circumference of the knob 10 and is fixed relative to the encoder rotating part 21a. The knob ring 41 is for the user to hold and rotate to input commands. The specific structural form of the encoder rotating part 21a and the encoder fixed part 21b is not limited. It can be a ring form with inner and outer rings, or other forms, which will not be elaborated here.

[0129] For example, the knob ring 41 may include a ring bracket 411 and a decorative ring 412. The decorative ring 412 surrounds the ring bracket 411, and the outer surface of the decorative ring 412 can form the outer peripheral surface of the knob 201. The knob ring 41 consists of two parts, which can meet the connection requirements with encoders, etc. through the structural design of the ring bracket 411, and also meet the appearance requirements of the knob 201 through the decorative ring 412. The appearance and material of the decorative ring 412 are not limited, and can be flexibly designed and processed according to requirements.

[0130] In some embodiments, the difference between the nominal diameter of the threaded hole 31211 and the nominal diameter of the screw 62a is 0.03mm-0.05mm.

[0131] In the above technical solution, the drive shaft 62 is a screw 62a that meshes with a threaded hole 31211. The difference between the nominal diameter of the threaded hole 31211 and the nominal diameter of the screw 62a is 0.03mm-0.05mm. When the drive shaft 62 drives the knob 201 to make linear movements, if the difference between the nominal diameter of the threaded hole 31211 and the nominal diameter of the screw 62a is too small, the screw 62a and the threaded hole 31211 may get stuck. However, a difference of 0.03mm-0.05mm improves the smoothness of transmission, allowing the knob 201 to make linear movements as expected and achieve precise adjustment. In addition, an appropriate diameter difference can reduce the friction between the screw 62a and the threaded hole 31211. If the diameter difference between the two is too small, the screw 62a will be in close contact with the threaded hole 31211, and a large frictional force will be generated during the relative movement. However, a difference of 0.03mm-0.05mm can effectively reduce friction, reduce wear and heat generation, extend the service life of the screw 62a and the threaded hole 31211, and improve the reliability and stability of the knob 201 movement while ensuring transmission.

[0132] Furthermore, this difference range ensures the fitting accuracy between the screw 62a and the threaded hole 31211. An excessively large difference may cause the screw 62a to wobble within the threaded hole 31211, affecting the movement accuracy of the knob 201; while an excessively small difference may lead to assembly difficulties or movement jamming due to machining errors and other factors. A difference of 0.03mm-0.05mm ensures smooth assembly and movement of the screw 62a while effectively controlling its radial displacement, thereby reducing wobbling and jamming during knob 201 movement. It also maintains good stability when the knob 201 is in the extended position and the user needs to operate it.

[0133] See Figure 11 In some embodiments, the driver 202 is disposed on the knob 201 (i.e., the driver 202 is directly or indirectly fixedly connected to the knob 201), and the driver 202 is driven to cooperate with the panel assembly 100 to reciprocate in a straight line relative to the panel assembly 100 in sync with the knob 201.

[0134] In the above technical solution, the driver 202 is disposed on the knob 201 and cooperates with the panel assembly 100 to drive the knob 201 to reciprocate. There is no transmission cooperation between the driver 202 and the knob 201, which simplifies the structure of the knob 201 and allows for diverse selection of the knob 201. In addition, when the knob 201 is maintained or replaced, the knob 201 and the driver 202 can be disassembled and replaced as a whole, thereby simplifying the maintenance or replacement process, reducing maintenance costs, and improving the maintainability and scalability of the panel assembly 1000.

[0135] In the embodiments of this application, the driver 202 is disposed on the knob 201. The driver 202 can be completely built into the knob 201. For example, the motor 61 is installed in the internal cavity of the knob 201, and the knob 201 is moved by the transmission mechanism such as gears and screws 62a in cooperation with the panel base 102. Combined with the waterproof and sealed design of the knob 201, water is unlikely to enter the internal cavity of the knob 201 and cause damage to the motor 61, thus improving the reliability of the reciprocating motion of the knob 201. Of course, the driver 202 can also be at least partially exposed on the knob 201, but fixedly connected to the knob 201 and moving synchronously. For example, the outer shell of the driver 202 is fixed to the bottom plate 22 of the knob 201 by means of threaded connection, snap-fit ​​connection, etc., and the output shaft of the driver 202 cooperates with the panel assembly 100 to realize the movement of the knob 201.

[0136] See Figure 11 In some embodiments, the panel assembly 100 includes a panel base 102 disposed inside the panel 101. The panel base 102 includes a third rod 1021 with a threaded hole 31211 inside. The knob 201 includes a knob base 203. The driver 202 includes a motor 61 and a drive shaft 62. The motor 61 is disposed in the knob base 203 and is used to drive the drive shaft 62 to rotate. The drive shaft 62 extends into the third rod 1021 and is a screw 62a that meshes with the threaded hole 31211. The knob base 203 is in a rotation-limiting engagement with the panel base 102 to prevent the knob base 203 from rotating relative to the panel base 102.

[0137] In the above technical solution, the drive shaft 62 (screw 62a) is driven by the motor 61 to rotate in the threaded hole 31211 of the third rod 1021. Since the third rod 1021 is set on the panel base 102 and the panel base 102 is fixedly set, the rotational motion of the drive shaft 62 is converted into the linear motion of the knob base 203, thereby realizing the extension and retraction of the knob 201. Moreover, the threaded transmission has self-locking property. When the motor 61 stops driving, the knob 201 can remain in the current position and will not retract due to external force (the force of the user operating the knob 201). Thus, the stepless adjustment of the extension height of the knob 201 is realized, and the knob 201 can be suspended at any height relative to the panel 101.

[0138] In addition, by mounting the motor 61 on the knob base 203 and engaging the drive shaft 62 with the third rod 1021 on the panel base 102, a relatively compact structure is formed, reducing additional connecting parts and space occupation. This makes the integration of the entire panel assembly 100 and knob device 200 more efficient, facilitating installation and use in space-constrained equipment and contributing to the miniaturization of the knob 201.

[0139] Combination Figure 12 and Figure 13In some embodiments, the first guide structure 7121a includes a plurality of first rods 7121 disposed on the panel base 102, and the second guide structure 3121a includes a plurality of second rods 3121 disposed on the knob base 203. The plurality of first rods 7121 and the plurality of second rods 3121 are sleeved and guided in a one-to-one correspondence, and the plurality of first rods 7121 are arranged around the third rod 1021.

[0140] In the above technical solution, multiple first rods 7121 and multiple second rods 3121 are connected and guided one-to-one. Compared with a single guide structure, this can more effectively restrict the rotation of the knob seat 203 relative to the panel seat 102. The setting of multiple guide points makes the constraint on the knob seat 203 more uniform during movement, reducing the shaking and deviation that may occur due to single-point guidance, thereby improving the linearity and stability of the knob 201's movement. The multiple first rods 7121 are arranged around the third rod 1021, distributing the force borne by the knob seat 203 during movement. When the knob 201 is subjected to external force (the force of the user operating the knob 201) or the driver 202 drives the knob seat 203 to move, the multiple guide rods share the load, reducing the force on a single guide rod, improving the load-bearing capacity of the entire guide structure, extending the service life of the guide structure, and reducing the risk of structural damage due to overload.

[0141] In addition, the corresponding engagement of multiple first rods 7121 and second rods 3121 can play a positioning and guiding role during the assembly process. This makes it easier for operators to accurately assemble the knob seat 203 with the panel seat 102, reduce assembly errors, ensure the matching accuracy between the guide rods, and thus improve the overall assembly quality of the equipment.

[0142] In the embodiments of this application, the cross-sectional shape of the first rod 7121 and the second rod 3121 is not limited. For example, both the first rod 7121 and the second rod 3121 are cylindrical, or they are square or polygonal. The number and arrangement of the first rod 7121 and the second rod 3121 are not limited. For example, there are four first rods 7121, which are arranged around the third rod 1021. The four first rods 7121 are located on a circle with the third rod 1021 as the center and are evenly spaced. When multiple sets of first rods 7121 and second rods 3121 are sleeved and guided, the lengths and cross-sectional areas of the multiple second rods 3121 may be different. For example, Figure 12 and Figure 13As shown, the multiple second rods 3121 can be divided into two groups: one group of circular second rods c and one group of circular second rods d. The circular second rod c corresponds to the circular second rod c on the panel base 102, and the circular second rod d corresponds to the square first rod f on the panel base 102. The length of the circular second rod c is longer than that of the circular second rod d, and the cross-sectional area of ​​the circular second rod c is smaller than that of the circular second rod d. Therefore, when the panel base 102 and the knob base 203 are engaged, the circular second rod c engages with the circular second rod c first, which plays a positioning role and facilitates the subsequent engagement of the circular second rod d with the square first rod f.

[0143] See Figure 10 In some embodiments, the knob 201 includes a core portion 10a and a rotating portion 10b. The rotating portion 10b is rotatably engaged with the core portion 10a, allowing it to rotate relative to the core portion 10a. The rotating portion 10b includes a knob ring 41 defining the outer circumferential surface of the knob 201. The knob 201 includes a screen 51, which is fixed relative to the core portion 10a. Thus, the screen 51 does not rotate, facilitating user information viewing. However, this is not a limitation; in other embodiments of this application, the screen 51 can also be designed to be fixed relative to the rotating portion 10b. The type of screen 51 is not limited; for example, it can be a pure display screen, a touch screen, or a voice-interactive screen, etc.

[0144] For example, the screen 51 can be located at the outer axial end of the knob ring 41. "Outer axial end of the knob ring 41" refers to the end of the knob 201 axially away from the interior of the panel 101. In the above technical solution, setting the screen 51 at the outer axial end of the knob ring 41 allows the user to directly see relevant operation feedback and display information on the knob 201 when operating it. For example, if the screen 51 is set on the knob 201 of an air conditioner 10000, when the user rotates the knob 201 to adjust the temperature, the screen 51 can display the currently set temperature value in real time. Thus, the user can promptly understand whether the operation of rotating the knob 201 to adjust the temperature is effective and the current status of the device. The interaction is more intuitive, improving the convenience and accuracy of user operation. Furthermore, integrating the screen 51 onto the knob 201 eliminates the need for additional display areas in other parts of the device, saving overall space on the knob 201.

[0145] For example, refer to Figures 2-5 , Figure 8The core part 10a includes a knob bracket 31, which is an integrated structural component and includes a connecting section 312 and a supporting section 311. The connecting section 312 includes a second guide structure 3121a. The supporting section 311 is located at the axial outer end of the connecting section 312, that is, the end near the outer side of the panel 101, and defines a mounting groove 311a that opens outward, that is, towards the outer side of the panel 101. The screen 51 is assembled in the mounting groove 311a, thereby improving the installation stability and working reliability of the screen 51.

[0146] In the above technical solution, the knob bracket 31 adopts an integrated structural component, which reduces the number of parts and assembly processes, and improves the stability and reliability of the structure. The knob bracket 31 includes a support section 311 and a connecting section 312. The support section 311 is located at the axial outer end of the connecting section 312 and defines a mounting groove 311a that opens to the outside. The screen 51 is installed in the mounting groove 311a. This utilizes the internal space of the knob bracket 31 to integrate the screen 51 into the knob 201. Without affecting the rotation function of the knob 201, the display function is integrated, providing users with more information display and interaction methods.

[0147] For example, combined Figure 2 and Figure 9 The knob 201 also includes an outer cover 52, which is in the form of a cover and includes a cover plate 521 and a cover plate 522. The cover plate 521 covers the outside of the screen 51, and the cover plate 522 extends from the edge of the cover plate 521 toward the inside and surrounds the support section 311 and is engaged with the support section 311.

[0148] In the above technical solution, the cover plate 521 is placed on the outside of the screen 51, which can protect the screen 51 from being scratched by sharp objects, protect the integrity of the screen 51 and its display function, and prevent dust, stains and other contaminants from adhering to the screen 51, thereby reducing damage to the screen 51 and reducing the problem of unclear display caused by dust entering the screen; the cover plate 522 surrounds the perimeter of the screen 51 and is snapped into the support section 311. First, the cover plate 522 is set without obstructing the screen 51 while meeting the installation requirements. Second, it does not require additional connectors or complex installation structures. The snap-fit ​​connection method is simple to operate and can be quickly assembled, improving production efficiency. Moreover, the outer cover 52 and the screen 51 can be relatively fixed without relative rotation, and there will be no friction between them. Of course, this application is not limited to this. For example, in other embodiments, the outer cover 52 can also be set to be relatively fixed with the knob ring 41, which will not be elaborated here.

[0149] Combination Figure 14 and Figure 15In some embodiments, the panel assembly 100 includes a panel base 102 and a second sealing ring 8. The panel base 102 is mounted on the inner side of the panel 101 and includes a first ring 721 surrounding the knob 201. The second sealing ring 8 is disposed on the inner side of the panel 101 and is sealed between the first ring 721 and the panel 101.

[0150] In the above technical solution, the second sealing ring 8 is sealed between the first ring 721 of the panel base 102 and the panel 101, which can prevent external moisture from seeping in through the clearance hole 11 and entering the equipment through the gap between the panel 101 and the panel base 102, thereby damaging other components inside the equipment; when the knob 201 is in the extended position, the first sealing part is compressed between the bottom plate 22 and the second sealing ring 8, forming a tight circumferential abutment seal, thereby effectively preventing moisture from flowing further into the internal space of the panel base 102 that houses the knob 201, reducing the risk of damage to the internal electrical components of the knob 201 due to moisture, and improving the reliability and service life of the knob 201.

[0151] For example, the panel base 102 includes a cover 72 and a base 71. The cover 72 includes a first ring 721. The base 71 is located at the axial inner end of the first ring 721 (i.e., the end near the inner side of the panel 101) and is connected to the cover 72, so that the panel base 102 is in the form of a cover, and the knob 201 is covered inside the panel base 102.

[0152] See Figure 10 In some embodiments, the knob 201 includes a knob ring 41 and a bottom plate 22. The knob ring 41 is rotatable relative to the bottom plate 22. The bottom plate 22 is located on the axial inner side of the knob ring 41 and is always located on the inner side of the panel 101. A first sealing ring 23 is provided between the bottom plate 22 and the knob ring 41. The first sealing ring 23 extends around the circumference of the knob ring 41. The first sealing ring 23 is provided on one of the bottom plate 22 and the knob ring 41 and is clearance-fitted with the other of the bottom plate 22 and the knob ring 41.

[0153] A first sealing ring 23 is provided between the bottom end plate 22 and the knob ring 41. The first sealing ring 23 extends around the circumference of the knob ring 41. The first sealing ring 23 is disposed on one of the bottom end plate 22 and the knob ring 41, and is in clearance fit with the other of the bottom end plate 22 and the knob ring 41. That is, the first sealing ring 23 can be disposed on the bottom end plate 22, and the first sealing ring 23 is in clearance fit with the knob ring 41. For example, as shown in the figure, the first sealing ring 23 is arranged around the outer periphery of the bottom end plate 22. 3. The first sealing ring 23 is fitted with the knob ring 41 with a clearance, making it difficult for moisture, dust, etc. to enter the space between the bottom plate 22 and the knob ring 41; or the first sealing ring 23 is provided on the knob ring 41, and the first sealing ring 23 is fitted with the bottom plate 22 with a clearance. For example, as shown in the figure, the first sealing ring 23 is arranged around the outer periphery of the knob ring 41, and the first sealing ring 23 is fitted with the bottom plate 22 with a clearance, making it difficult for moisture, dust, etc. to enter the space between the bottom plate 22 and the knob ring 41.

[0154] In the above technical solution, a first sealing ring 23 is provided between the bottom end plate 22 and the knob ring 41. The first sealing ring 23 extends circumferentially around the knob ring 41. The first sealing ring 23 is located on one of the bottom end plate 22 and the knob ring 41, and is fitted with the other of the bottom end plate 22 and the knob ring 41 with a gap. Therefore, in actual use, even if the equipment is in a humid environment, moisture is unlikely to enter the space between the bottom end plate 22 and the knob ring 41, and thus enter the core of the knob 201 (e.g., the core part 10a). This reduces the risk of damage, short circuits, and corrosion to the internal electronic components of the knob 201 caused by water ingress, improving the waterproof performance of the knob 201 and increasing its reliability and service life. At the same time, the clearance fit between the first sealing ring 23 and the knob ring 41 ensures that there will be no friction between the rotating part 10b (knob ring 41) and the non-rotating part 10b (bottom plate 22) of the knob 201, thus preventing the rotation of the rotating part 10b (knob ring 41) of the knob 201 from being hindered, and ensuring the smooth rotation of the knob ring 41.

[0155] Combination Figure 14 and Figure 15 In some embodiments, the panel assembly 100 includes a panel base 102 and a second sealing ring 8. The panel base 102 is mounted on the inner side of the panel 101 and includes a first ring 721 surrounding the knob 201. The second sealing ring 8 is disposed on the inner side of the panel 101 and is sealed between the first ring 721 and the panel 101. The first sealing ring 23 surrounds the outer periphery of the bottom plate 22 and is axially clearance-fitted with the knob ring 41. When the knob 201 moves to the extreme extension position, the bottom plate 22 and the panel 101 are limited by the contact between the first sealing ring 23 and the second sealing ring 8.

[0156] In the above technical solution, the first sealing ring 23 surrounds the outer periphery of the bottom end plate 22 and has an axial clearance fit with the knob ring 41, so that there is no friction between the rotating part 10b (knob ring 41) and the non-rotating part 10b (bottom end plate 22) of the knob 201, thus preventing the rotation of the rotating part 10b (knob ring 41) of the knob 201 from being hindered, and ensuring the smooth rotation of the knob ring 41; when the knob 201 moves to the extreme extension position, the bottom end plate 22 and the panel 101 are limited by the contact between the first sealing ring 23 and the second sealing ring 8, thereby effectively To prevent moisture from flowing further into the interior space of the panel seat 102 that houses the knob 201, thus ensuring that the side of the bottom plate 22 away from the panel 101 is not corroded by moisture; in addition, when the knob 201 is in the extended position, the first sealing ring 23 and the second sealing ring 8 will generate a certain elastic force during the contact process, thereby preventing the knob 201 from continuing to move outward, and to a certain extent limiting the radial and axial shaking of the knob 201. The elasticity of the sealing ring can absorb some vibration and impact force, so that the knob 201 remains relatively stable in the extended position.

[0157] Combination Figure 14 and Figure 15 In some embodiments, the knob device 200 further includes a driver 202, which drives the knob 201 to reciprocate linearly between an extended position and a retracted position. For example, in the retracted position, the height difference between the outer end face of the knob 201 and the outer surface of the panel 101 does not exceed 4mm, that is, the height difference is -4mm to 4mm. In the retracted position, the outer end face of the knob 201 can be flush with the outer surface of the panel 101, can be retracted into the outer surface of the panel 101, or can be protruding from the outer surface of the panel 101, but the height difference (i.e., the distance along the direction of the panel 101) does not exceed 4mm, for example, it can be -4mm, -3.5mm, -3mm, -2.5mm, -2mm, -1.5mm, -1mm, -0.5mm, 0mm, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, etc. This reduces the possibility of accidental contact with the knob 201, lowering the risk and loss caused by misoperation. Furthermore, the recessed knob 201 is protected by the panel 101, reducing the impact and scratches from external objects. It also makes it difficult for dust and moisture to enter the knob 201, improving its protective performance. Specifically, when the panel 101 is facing forward, the front surface of the knob 201 is its outer surface, and the front surface of the panel 101 is its outer surface.

[0158] For example, in the extended position, the height difference between the outer end face of the knob 201 and the outer surface of the panel 101 is 5mm-20mm. That is, in the extended position, the height difference (i.e., the distance along the direction of the panel 101) between the outer end face of the knob 201 and the outer surface of the panel 101 is 5mm to 20mm, for example, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, etc. This satisfies the operational requirements without the knob 201 protruding excessively, thus simplifying the drive design, avoiding excessive space occupation, improving the user's operating feel, and preventing excessive shaking of the knob 201. Specifically, when the panel 101 is facing forward, the front end face of the knob 201 is the outer surface of the knob 201, and the front surface of the panel 101 is the outer surface of the panel 101.

[0160] The type of air conditioner 10000 is not limited. For example, it can be an integrated air conditioner, such as a kitchen air conditioner, a portable air conditioner, or a window air conditioner; it can also be a split air conditioner, such as a split wall-mounted unit, a split floor-standing unit, a ceiling-mounted air conditioner, or a built-in air conditioner.

Thus, users can adjust parameters such as temperature, fan speed, and mode of the air conditioner 10000 by rotating the knob 201, improving the operability of the air conditioner 10000. Furthermore, the knob 201 can extend outward when the control parameters of the air conditioner 10000 need adjustment and retract inward when the control parameters do not need adjustment, increasing the interactivity and fun of the air conditioner 10000 and meeting users' needs for personalized products.
