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.

[0078] Hereinafter, with reference to the accompanying drawings, a panel component 1000 according to a first aspect embodiment of the present invention will be described.

[0079] See Figure 1 , Figure 2 and Figure 3 The panel component 1000 includes a panel 101 and a knob 201. The panel 101 has a clearance hole 11. The knob 201 is disposed opposite to the clearance hole 11 and is movable relative to the panel 101. It repeatedly passes through the clearance hole 11 and extends outward and retracts relative to the panel 101. The knob 201 includes a knob ring 41 and a bottom plate 22a. The knob ring 41 is rotatable relative to the bottom plate 22a. The knob ring 41 passes through the clearance hole 11 as the knob 201 extends and retracts. The bottom plate 22a is disposed on the inner side of the panel 101. A first sealing ring 23 is provided between the bottom plate 22a and the knob ring 41. The first sealing ring 23 is disposed on one of the bottom plate 22a and the knob ring 41 and is in clearance fit with the other of the bottom plate 22a and the knob ring 41.

[0080] 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 100 is the panel of a household appliance. The type of household appliance is not limited. For example, it can be an air conditioner 10000, washing machine, refrigerator, microwave oven, rice cooker, water heater, gas stove, water purifier, electric fan, etc.

[0081] 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.

[0082] 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.

[0083] 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 outside of the panel 101 (extension movement), and the knob 201 moves towards the inside of the panel 101 (retraction movement). More specifically, "extension" means that the knob 201 moves from the inside of the panel 101 to the outside of the panel 101 through the clearance hole 11, allowing the knob 201 to protrude more from the outside of the panel 101; "retraction" means that the knob 201 moves from the outside of the panel 101 to the inside of the panel 101 through the clearance hole 11, allowing the knob 201 to retract more into the inside 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.

[0084] Alternatively, "retracting" refers to the knob 201 moving towards the inside of the panel 101, meaning the outer end face of the knob 201 moves towards the side closer to the panel 101. "Extending" refers to the knob 201 moving towards the outside of the panel 101, meaning the outer end face of the knob 201 moves away from the panel 101. The final retracted position of the knob 201 relative to the panel 101 can be: the outer end face of the knob 201 flush with the outer surface of the panel 101; the outer end face of the knob 201 retracted into the outer surface of the panel 101; or the outer end face of the knob 201 protruding from the outer surface of the panel 101, as long as the protrusion height of the knob 201 relative to the panel 101 in the retracted final state is less than the protrusion height of the knob 201 relative to the panel 101 in the extended final state. Here, "outer end face of the knob 201" refers to the side of the knob 201 away from the inside of the panel 101, that is, the side of the 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 knob 201 and the outer surface of panel 101 along the extension and retraction direction of knob 201.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] The knob 201 includes a knob ring 41 and a bottom plate 22a. The knob ring 41 is the part that is directly operated by the user. The user inputs commands by rotating the knob ring 41. It can rotate relative to the bottom plate 22a and is used to adjust the parameters of the device, switch function modes, etc. The knob ring 41 constitutes at least part of the rotating part of the knob 201.

[0089] 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 10. 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.

[0090] The bottom plate 22a is located on the axial inner side of the knob ring 41, that is, the side of the knob ring 41 away from the panel 101 (i.e. the outer side away from the panel 101), and the bottom plate 22a constitutes at least a portion of the non-rotating part of the knob 201.

[0091] The first sealing ring 23 can extend around the entire circumference of the knob ring 41. For example, the first sealing ring 23 is arranged around the outer circumference of the bottom plate 22a, and the first sealing ring 23 is in clearance fit with the knob ring 41, making it difficult for moisture, dust, etc., to enter the space between the bottom plate 22a and the knob ring 41. Alternatively, the first sealing ring 23 can be arranged around the outer circumference of the knob ring 41, and the first sealing ring 23 is in clearance fit with the bottom plate 22a, making it difficult for moisture, dust, etc., to enter the space between the bottom plate 22a and the knob ring 41. Of course, this application is not limited to this; the first sealing ring 23 can also be a non-continuous ring, for example, it can also be in a discontinuous form extending along the circumference of the knob ring 41.

[0092] Because the panel 101 has a clearance hole 11, the knob 201 can extend and retract relative to the panel 101 through this clearance hole 11. In actual use scenarios, the device may be in a humid environment, such as encountering splashed water, condensed liquid water droplets, or water stains left over from cleaning the device. Water may seep into the knob 201 along the edge of the clearance hole. Once water enters the knob 201, it may corrode the electronic components inside the knob 201, causing short circuits, component corrosion, and thus malfunction of the knob 201's rotation adjustment function, or trigger internal electrical faults, ultimately damaging the knob.

[0093] In the technical solution of this application, a first sealing ring 23 is provided between the bottom end plate 22a and the knob ring 41. The first sealing ring 23 extends around the entire circumference of the knob ring 41. The first sealing ring 23 is provided on one of the bottom end plate 22a and the knob ring 41, and is fitted with the other of the bottom end plate 22a and the knob ring 41 with a gap. Therefore, in actual use, even if the equipment is in a humid environment, it is difficult for moisture to enter the space between the bottom end plate 22a and the knob ring 41, and thus enter the core of the knob 201 rotation. 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 also prevents friction between the rotating part (such as the knob ring 41) and the non-rotating part (such as the bottom plate 22a) of the knob 201, thus ensuring the smooth rotation of the knob ring 41.

[0094] Furthermore, foreign objects or tiny particles are unlikely to enter the space between the bottom plate 22a and the knob ring 41, thus avoiding any impact on the knob 201. For example, when the knob 201 is equipped with a driver 202, which, exemplarily, includes a motor 61 and a screw, the knob 201 is driven by the screw. A first sealing ring 23 is arranged around the outer periphery of the bottom plate 22a, and the first sealing ring 23 is in clearance fit with the knob ring 41. As a result, dust is unlikely to enter the transmission part inside the knob 201, making it less likely for the knob 201 to jam during movement and improving the reliability of the knob 201's extension and retraction movements.

[0095] The knob ring 41 is rotatable relative to the bottom plate 22a, and the knob 201 is movable relative to the panel 101. By repeatedly extending outward and retracting relative to the panel 101 through the clearance hole 11, the knob 201 can extend outward from the panel 101 when needed for user operation; when not needed, the knob 201 retracts into the panel 101, saving space and avoiding potential problems such as bumps, dust accumulation, and accidental touches caused by the knob 201 protruding from the surface of the panel 101, thus improving the user experience.

[0096] The phrase "bottom plate 22a is located inside panel 101" means that the bottom plate 22a is always located inside panel 101, meaning that it will not move to the outside of panel 101 during the movement of knob 201. For example, the coverage area of ​​the bottom plate 22a can exceed the area of ​​the clearance hole 11, thereby ensuring the stability of knob 201 during movement and preventing it from easily detaching from panel 101 due to external forces, thus ensuring the reliability and safety of the device.

[0097] Combination Figure 4 and Figure 5 In some embodiments, the panel component 1000 further includes a panel base 102, which is installed inside the panel 101 and covers the knob 201. The panel base 102 includes a second ring 714, which is located on the side of the knob 201 away from the panel 101. The bottom plate 22a is a second circuit board 22, and the side of the second circuit board 22 away from the panel 101 has electrical components. The electrical components are opposite to the space inside the second ring 714, that is, the electrical components on the side of the second circuit board 22 away from the panel 101 are spatially located within the area enclosed by the second ring 714. The panel component 1000 also includes a driver 202, which is used to drive the knob 201 to reciprocate between an extended position and a retracted position. In the retracted position, the first sealing ring 23 and the second ring 714 form an abutment seal along the entire circumference of the first sealing ring 23, that is, the first sealing ring 23 and the second ring 714 are tightly fitted in the entire circumferential direction.

[0098] In the above technical solution, the panel holder 102 is installed inside the panel 101 and covers the knob 201, providing physical protection for the knob 201. The panel holder 102 can prevent external moisture, dust, debris and other objects from entering the knob 201, avoiding these impurities from adversely affecting the normal operation of the knob 201 and the performance of the electrical components on the second circuit board 22, thereby improving the reliability of the knob 201.

[0099] When in the retracted position, the first sealing ring 23 and the second ring 714 form an abutment seal along the entire circumference of the first sealing ring 23. As a result, the inner space of the second ring 714 is relatively closed, which further improves the waterproof and dustproof effect. Even if moisture enters the panel base 102 through the clearance hole 11 of the panel 101, it will be blocked by the first sealing ring 23 and the second ring 714, thereby protecting the electrical components on the second circuit board 22 from water corrosion, avoiding short circuits and component damage caused by water, and extending the service life of the equipment.

[0100] In the embodiments of this application, the extended position is the maximum position reached by the knob 201 extending out of the outside of the panel 101. At this time, most or all of the knob ring 41 is located on the outside of the panel 101, which is convenient for the user to operate. The retracted position is the minimum position reached by the knob 201 retracting into the inside of the panel 101. At this time, most or all of the knob ring 41 is located on the inside of the panel 101, which is used to protect the knob ring 41 and reduce the external space occupied by the knob 201.

[0101] In the embodiments of this application, the structure of the panel base 102 is not limited. For example, the panel base 102 can be integrally formed, and the panel base 102 is a complete component; or it can be a split panel base 102. For example, the panel base 102 includes a motor base 71 and a housing 72. The housing 72 is installed on the panel 101 and includes a first ring 721. The first ring 721 is arranged around the knob 201. The motor base 71 is located inside the housing 72 and installed on the housing 72. The motor base 71 covers the axial inner end of the first ring 721. A second ring 714 is arranged on the motor base 71 and extends from the motor base 71 toward the bottom plate 22a so as to abut and seal against the first sealing ring 23 around its entire circumference.

[0102] Combination Figure 5 and Figure 6 In some embodiments, the first sealing ring 23 includes a first annular portion 231, and an annular groove 231a is formed on the inner circumference of the first annular portion 231. The edge of the bottom end plate 22a is embedded in the annular groove 231a. The first annular portion 231 includes a first sealing portion 2311 and a second sealing portion 2312 clamped on both sides of the bottom end plate 22a along the axial direction of the knob ring 41. The first sealing portion 2311 is located on the side of the second sealing portion 2312 closer to the panel 101. The first sealing ring 23 abuts against the second ring 714 through the second sealing portion 2312 to seal.

[0103] In the above technical solution, the edge of the bottom plate 22a is embedded in the annular groove 231a, so that the first sealing ring 23 and the bottom plate 22a are tightly fitted, realizing the positioning and fixing of the first sealing ring 23 and the bottom plate 22a. The installation is simple and can ensure the stability of the relative position between the two, providing a basis for subsequent sealing fit.

[0104] The first annular portion 231 includes a first sealing portion 2311 and a second sealing portion 2312 clamped on both sides of the bottom end plate 22a along the axial direction of the knob ring 41. The first sealing portion 2311 is located on the side of the second sealing portion 2312 closer to the panel 101. The first sealing ring 23 abuts and seals with the second ring 714 through the second sealing portion 2312, that is, the upper end of the second ring 714 abuts and seals with the second sealing portion 2312. The sealing mating surface is perpendicular to the movement direction of the knob 201 and parallel to the movement direction of the knob 201 relative to the sealing mating surface. This sealing fit reduces the jamming problem caused by the sealing mating surface being parallel to the movement direction of the knob 201. Due to factors such as processing errors and friction, jamming can easily occur when the sealing mating surface is parallel to the movement direction of the knob 201, hindering the extension and retraction of the knob 201. However, when the sealing mating surface is perpendicular to the movement direction of the knob 201, the retraction movement of the knob 201 can be used to ensure a good abutment seal between the second sealing part 2312 and the bottom plate 22a, which not only ensures the sealing effect but also ensures the smooth movement of the knob 201.

[0105] Combination Figure 7 and Figure 8 In some embodiments, the panel base 102 includes a first ring 721 surrounding the knob 201, and the panel component 1000 includes a second sealing ring 8. 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 bottom plate 22a is always located inside the second sealing ring 8. In the extended position, the first sealing part 2311 is sealed between the bottom plate 22a and the second sealing ring 8 to form an abutment seal with the second sealing ring 8 around the entire circumference of the first sealing ring 23.

[0106] 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 2311 is compressed between the bottom plate 22a 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.

[0107] In addition, the first sealing part 2311 and the second sealing ring 8 form an abutment seal along the entire circumference of the first sealing ring 23, preventing moisture from flowing further into the internal space of the panel seat 102 that houses the knob 201. It can also be combined with the drainage design (as described in the drainage passage below) to orderly drain the moisture that has entered the internal space of the panel seat 102 from the clearance hole 11, thereby ensuring the safety of the knob 201 inside the panel 101 and other components inside the equipment.

[0108] Combination Figure 7 and Figure 8 In some embodiments, the first sealing ring 23 includes a second annular portion 232, which is arranged sequentially with the first annular portion 231 along the axial direction of the knob ring 41. The second annular portion 232 extends from the inner ring of the first sealing portion 2311 toward the direction close to the knob ring 41 and is in axial clearance fit with the knob ring 41.

[0109] In the above technical solution, the second annular portion 232 extends from the inner ring of the first sealing portion 2311 toward the direction close to the knob ring 41. The structure is simple and reliable, and it allows the second annular portion 232 to get closer to the knob ring 41, so that the second annular portion 232 can be axially clearance-fitted with the knob ring 41, thereby sealing and protecting the knob ring 41 and the bottom plate 22a. This prevents moisture from entering the inside of the knob 201 (e.g., the core portion 10a), improving the waterproof performance of the knob 201 and increasing its reliability and service life. At the same time, the clearance fit between the second annular portion 232 and the knob ring 41 also prevents friction between the rotating part (e.g., the knob ring 41) and the non-rotating part (e.g., the bottom plate 22a) of the knob 201, thus ensuring the smooth rotation of the knob ring 41.

[0110] In embodiments of this application, a portion of the knob ring 41 may extend downward so that the knob ring 41 can be closer to the second annular portion 232, thereby allowing the second annular portion 232 of the first sealing portion 2311 to have an axial clearance fit.

[0111] In the embodiments of this application, the first sealing ring 23 and the knob ring 41 are in clearance fit, for example, as shown in... Figure 8 As shown, the fit gap between the first sealing ring 23 and the knob ring 41 is G1. The size of the fit gap G1 can be set between 0.1-1mm. Thus, the size of the fit gap G1 will not be too large, which would cause the seal to fail, nor too small, which would affect the normal rotation of the knob ring 41.

[0112] Combination Figure 1 and Figure 7 In some embodiments, the panel component 1000 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 disposed around 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.

[0113] In the above technical solution, the panel base 102 includes a first ring 721 surrounding the knob 201, forming an internal space to accommodate the knob 201 and providing physical protection for the knob 201. The first ring 721 can prevent moisture, dust, debris, etc. from entering the knob 201, avoiding these impurities from adversely affecting the normal operation of the knob 201 and the performance of the electrical components on the second circuit board 22, thus improving the reliability of the knob 201. The second sealing ring 8 is sealed between the first ring 721 of the panel base 102 and the panel 101, preventing 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.

[0114] Combination Figure 7 and Figure 8 In some embodiments, the second sealing ring 8 includes an annular portion 81 and an outer flange portion 82. The outer flange portion 82 is sealed between the first annular ring 721 and the panel 101. The annular portion 81 is connected to the outer flange portion 82 and extends into the first annular ring 721.

[0115] In the above technical solution, the outer flange portion 82 of the second sealing ring 8 is sealed and clamped between the first ring 721 and the panel 101. Specifically, during installation, the second sealing ring 8 is compressed between the first ring 721 and the panel 101. Utilizing the elasticity of the outer flange portion 82, it can tightly fit the surfaces of the first ring 721 and the panel 101, filling the gap between them, thereby achieving a seal. This prevents 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, thus damaging other components inside the equipment. The ring portion 81 is connected to the outer flange portion 82 and extends into the first... Within the ring 721, on the one hand, it provides a clear installation position for the second sealing ring 8. Specifically, during installation, the ring portion 81 can be inserted into the first ring 721 to ensure that the outwardly flanged portion 82 can be correctly sealed and clamped between the first ring 721 and the panel 101, avoiding poor sealing caused by installation deviation. On the other hand, the ring portion 81 extends into the first ring 721 to get closer to the first sealing ring 23, thereby helping the first sealing portion 2311 and the second sealing ring 8 to form an abutment seal along the entire circumference of the first sealing ring 23 when in the extended position, which in turn helps to improve the waterproof performance of the knob 201.

[0116] See Figure 9 In some embodiments, the inner surface of the panel 101 has a protruding insert 111 located around the clearance hole 11. The insert 111 is formed as an arc-shaped piece extending circumferentially along the clearance hole 11. The annular portion 81 defines a slot 81a that opens in the direction toward the panel 101. The slot 81a is shaped and correspondingly inserted into the insert 111.

[0117] In the above technical solution, the protruding insert 111 on the inner surface of the panel 101 is fitted and correspondingly inserted into the slot 81a defined by the ring portion 81. This can restrict the movement of the second sealing ring 8 in the radial direction of the ring portion 81. Compared with simple clamping sealing, the insertion structure can provide greater friction and constraint force, so that the second sealing ring 8 is firmly fixed on the panel 101 through the insertion structure and will not easily displace or loosen, thereby ensuring the long-term stability of the sealing performance.

[0118] The form-fitting insertion of the insert 111 and the slot 81a provides a clear positioning reference for the installation of the second sealing ring 8. During the assembly process, the operator can quickly and accurately install the second sealing ring 8 into place, reducing assembly errors and ensuring a tighter sealing fit between the second sealing ring 8 and the panel 101, the first ring 721, and the first sealing ring 23, further improving the waterproof performance.

[0119] See Figure 9In some embodiments, multiple inserts 111 are spaced apart circumferentially along the clearance hole 11, and multiple slots 81a are spaced apart to engage with the multiple inserts 111 one-to-one. This creates multiple fixing points along the entire circumference of the clearance hole 11. Compared to the engagement of a single insert 111 with a slot 81a, the one-to-one engagement of multiple slots 81a with multiple inserts 111 more effectively resists forces and vibrations from all directions, preventing the second sealing ring 8 from rotating or shifting circumferentially, thus enhancing the stability of the installation. For example, four inserts 111 are evenly spaced circumferentially along the clearance hole 11, and four slots 81a are also evenly spaced to engage with the multiple inserts 111 one-to-one. This evenly distributed distribution of the multiple inserts 111 around the clearance hole 11 ensures a more uniform fixing force on the second sealing ring 8, preventing deformation or damage caused by uneven local force, and further improving the service life and sealing performance of the sealing ring.

[0120] Combination Figure 9 , Figure 10 and Figure 11 In some embodiments, there are multiple inserts 111 and they are spaced apart circumferentially along the clearance hole 11. A first drain hole 111a is formed between adjacent inserts 111. The end of the second sealing ring 8 away from the panel 101 forms a second drain hole 8a at the corresponding first drain hole 111a. After the inserts 111 and the slots 81a are inserted and engaged one by one, the first drain hole 111a and the second drain hole 8a are connected. The first ring 721 forms a third drain hole 721a at the corresponding second drain hole 8a.

[0121] For example, such as Figure 10 and Figure 11 As shown, the panel component 1000 is vertically arranged, and the knob 201 can reciprocate in the horizontal direction through the clearance hole 11, extending outward and retracting relative to the panel 101. The first drain port 111a and the second drain port 8a are correspondingly arranged and located at the lowest point of the lower part of the knob 201. When the equipment is in a humid environment or is accidentally splashed with water, the water enters along the periphery of the clearance hole 11, then flows along the inner wall of the ring portion 81, gradually gathers at the lowest point of the lower part of the knob 201, passes through the first drain port 111a and the second drain port 8a, flows to the inner wall of the first ring 721, and then continues to flow out through the third drain port 721a on the first ring 721, finally draining the water to a specific location.

[0122] In the above technical solution, the end of the second sealing ring 8 away from the panel 101 forms a second drain port 8a at the corresponding first drain port 111a. After the insert 111 and the slot 81a are inserted and matched one by one, the first drain port 111a and the second drain port 8a are connected, so that the water flowing in from the clearance hole 11 can flow to the first ring 721 through the first drain port 111a and the second drain port 8a. The first ring 721 forms a third drain port 721a at the corresponding second drain port 8a, so that the water in the first ring 721 can be discharged through the third drain port 721a into the internal space of the panel seat 102 that accommodates the knob 201 formed by the first ring 721. This forms a specific drainage channel, which orderly discharges the water flowing into the clearance hole 11 to a specific position, effectively preventing the water from accumulating in the internal space of the panel seat 102 that accommodates the knob 201, avoiding problems such as moisture and damage to the internal components of the knob 201 caused by water accumulation, and improving the reliability and service life of the knob 201. For example, in humid environments or when equipment is accidentally splashed with water, the drainage channel can drain the water in time, ensuring that knob 201 is not damaged by water immersion.

[0123] In the above technical solution, a balance between sealing and drainage is achieved by setting up a drainage channel while ensuring sealing performance. The sealing between the second sealing ring 8 and the first ring 721, the panel 101, and the second sealing ring 8 and the first sealing ring 23 can prevent most of the water from seeping into the inside of the knob 201 (e.g., the core part 10a), while the drainage channel is used to drain a small amount of water that may enter. This ensures the waterproof capability of the knob 201 and avoids potential problems caused by the inability to drain water due to complete sealing.

[0124] Combination Figure 7 and Figure 8 In some embodiments, the panel component 1000 further includes a driver 202, which drives the knob 201 to reciprocate between an extended position and an in retracted position. The bottom plate 22a is always located inside the second sealing ring 8. In the extended position, the bottom plate 22a and the panel 101 are abutted and limited by the first sealing ring 23 and the second sealing ring 8. The second sealing ring 8 and the first sealing ring 23 form an abutment seal along the entire circumference of the first sealing ring 23.

[0125] In the above technical solution, the driver 202 is used to drive the knob 201 to reciprocate between the extended position and the retracted position. When the knob 201 is in the extended position, the second sealing ring 8 and the first sealing ring 23 form an abutting seal along the entire circumference of the first sealing ring 23, thereby effectively preventing moisture from flowing further into the internal space of the panel seat 102 that accommodates the knob 201, thus ensuring that the side of the bottom plate 22a away from the panel 101 is not corroded by water vapor. 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 abutting process, thereby preventing the knob 201 from continuing to move outward, and limiting the radial and axial shaking of the knob 201 to a certain extent. 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.

[0126] Combination Figure 7 and Figure 8 In some embodiments, the second sealing ring 8 includes an annular portion 81 and an outer flange portion 82. The outer flange portion 82 is sealed between the first annular ring 721 and the panel 101. The annular portion 81 is connected to the outer flange portion 82 and extends into the first annular ring 721. The second sealing ring 8 abuts against the first sealing ring 23 through the annular portion 81 to seal.

[0127] In the above technical solution, the outer flange portion 82 of the second sealing ring 8 is sealed and clamped between the first ring 721 and the panel 101. Specifically, during installation, the second sealing ring 8 is compressed between the first ring 721 and the panel 101. Utilizing the elasticity of the outer flange portion 82, it can tightly fit the surfaces of the first ring 721 and the panel 101, filling the gap between them, thereby achieving a seal. This prevents 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, thus damaging other components inside the equipment. The ring portion 81 is connected to the outer flange portion 82 and extends into the first ring 721. The second sealing ring 8 abuts against the first sealing ring 23 through the ring portion 81, effectively preventing moisture from further flowing into the internal space of the panel base 102 that houses the knob 201. This reduces the risk of damage to the internal electrical components of the knob 201 due to moisture and improves the reliability and service life of the knob 201.

[0128] Combination Figure 7 and Figure 8In some embodiments, the second sealing ring 8 surrounds the knob ring 41. The second sealing ring 8 also includes an inner flange portion 83, which is located within the ring area of ​​the ring portion 81 and is connected to the end of the ring portion 81 near the panel 101. The inner end of the knob ring 41 is provided with a stop portion 413, which extends toward the ring portion 81 and is radially clearance-fitted with the ring portion 81. The stop portion 413 is always located inside the inner flange portion 83. The panel component 1000 also includes a driver 202, which is used to drive the knob 201 to reciprocate between an extended position and a retracted position. In the extended position, the stop portion 413 and the inner flange portion 83 are axially clearance-fitted.

[0129] In the above technical solution, the stop portion 413 and the inner flange portion 83 are fitted with an axial clearance, and the stop portion 413 and the ring portion 81 are fitted with a radial clearance. Therefore, if moisture wants to enter the internal space of the panel base 102 accommodating the knob 201, it needs to pass through two narrow, bent gaps. This increases the complexity and reliability of the sealing structure, further preventing impurities and moisture from entering through the gap between the knob 201 and the clearance hole 11 on the panel 101, thus improving the reliability of the knob 201. Furthermore, the axial clearance fit between the stop portion 413 and the inner flange portion 83 prevents tight contact and friction between them. During the rotation of the knob 201, the clearance avoids friction caused by direct contact between components, ensuring smooth rotation of the knob 201.

[0130] In the embodiments of this application, exemplarily, such as Figure 8 As shown, the fit clearance between the stop part 413 and the inner flange part 83 is G2, and the radial clearance fit between the stop part 413 and the ring part 81 is G3. The sizes of the fit clearance G2 and the clearance fit G3 can both be set between 0.1-1mm. Thus, the sizes of the fit clearance G2 and the clearance fit G3 are neither too large, which would cause the seal to fail, nor too small, which would affect the normal rotation of the knob ring 41.

[0131] Combination Figure 1 and Figure 12In some embodiments, the panel component 1000 further includes a driver 202, which drives the knob 201 to reciprocate between an extended position and a retracted position. Thus, the knob 201, driven by the driver 202, can reciprocate through the clearance hole 11 to move between the extended and retracted positions, achieving extension and retraction relative to the panel 101. When the knob 201 is needed, it extends out of the panel 101 for convenient 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, thus improving the user experience. In addition, the actuator 202 can drive the knob 201 to reciprocate through the clearance hole 11, so the user does not need to manually operate the extension and retraction of the knob 201. For example, the actuator 202 can be triggered to work through other control methods of the knob 201 (such as touch screen button, key button, voice command, etc.) to realize the automatic movement of the knob 201.

[0132] In the embodiments of this application, the power source of the driver 202 is not limited. For example, the driver 202 can be driven by electric, pneumatic, hydraulic or other driving forces. The driver 202 can be set on the panel 101 and used alone to drive the knob 201 to extend and retract. Of course, other drivers 202 outside the panel 101 can also drive the knob 201 to extend and retract.

[0133] See Figure 12 In some embodiments, the panel component 1000 further includes a panel base 102, which is mounted on the inner side of the panel 101. The driver 202 is mounted on the panel base 102 and is driven to engage with the knob 201 to drive the knob 201 to reciprocate between an extended position and an in retracted position relative to the driver 202.

[0134] In the above technical solution, by placing the driver 202 on the panel base 102, which is located inside the panel 101, the driver 202 is close to the knob 201, facilitating direct driving of the knob 201. This makes the structure of the entire panel component 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 ensures smooth movement of the knob 201, avoiding the shaking and jamming that may occur during manual operation, thus improving the stability of the knob 201's movement.

[0135] In the embodiments of this application, the driver 202 drives the knob 201 to reciprocate between an extended position and a retracted position relative to the driver 202. The driving method is not limited; exemplarily, it can be a threaded screw drive. The driver 202 can be a motor 61, with the output shaft of the motor 61 connected to the screw. The core portion 10a can be threadedly engaged with the screw. When the motor 61 drives the screw to rotate, the core portion 10a is restricted from rotating, and the rotational motion of the screw is converted into the reciprocating translational motion of the core portion 10a, thereby realizing the reciprocating motion of the knob 201.

[0136] For example, a gear and rack drive can also be used. The driver 202 can be a motor 61, with a gear mounted on the output shaft of the motor 61, and the core part 10a connected to the rack. When the motor 61 drives the gear to rotate, the gear meshes with the rack, converting the rotational motion of the gear into the reciprocating translational motion of the rack, which in turn drives the core part 10a and the knob 201 to perform reciprocating translational motion.

[0137] 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.

[0138] Combination Figure 12 , Figure 13 and Figure 15In 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 knob 201 includes a core part 10a and a rotating part 10b. The rotating part 10b is rotatably engaged with the core part 10a so as to be rotatable relative to the core part 10a. The rotating part 10b includes a knob ring 41 and the encoder rotating part 21a. The core part 10a includes a bottom plate 22a and the encoder fixing part 21b. The driver 202 is engaged with the core part 10a to drive the core part 10a to translate.

[0139] 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 rotating part 10b includes a knob ring 41 and the encoder rotating part 21a. 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 with inner and outer rings or other forms, which will not be elaborated here.

[0140] The core portion 10a includes a bottom plate 22a and an encoder mounting portion 21b. The driver 202 cooperates with the core portion 10a to drive the core portion 10a to translate. Thus, the encoder mounting portion 21b provides a fixed reference for the encoder 21, ensuring that the encoder 21 can accurately and stably measure the rotation information of the encoder rotating portion 21a relative to the encoder mounting portion 21b, thereby accurately transmitting the user's control commands and improving the accuracy and stability of the knob 201 operation.

[0141] Combination Figures 12-16In some embodiments, the panel base 102 includes a motor base 71 and a housing 72. The housing 72 is mounted on the panel 101 and includes a first ring 721 surrounding the knob 201. The motor base 71 is located inside the housing 72 and mounted thereon. The motor base 71 covers the axial inner end of the first ring 721. The motor base 71 is an integral structural component and includes a seat end plate 711 and a first rod 712. The seat end plate 711 is located inside the knob 201, and the first rod 712 extends from the seat end plate 711 into the knob 201. The driver 202 includes a motor 61 and a drive shaft 62. The motor 61 is mounted on the inner side of the end plate 711. The drive shaft 62 is connected to the motor 61 and extends into the first rod 712. The core part 10a includes a second rod 3121, which extends into the first rod 712. The second rod 3121 has a threaded hole 31211 and is sleeved on the outside of the drive shaft 62. The drive shaft 62 is a screw and meshes with the threaded hole 31211. The panel seat 102 is in rotation-limiting cooperation with the core part 10a to limit the rotation of the second rod 3121 relative to the first rod 712.

[0142] In the above technical solution, the housing 72 is arranged around the knob 201, and the motor base 71 covers the axial inner end of the first ring 721, which can prevent external moisture and dust from entering the inside of the knob 201. The drive shaft 62 is connected to the motor 61 and extends into the first rod 712. The core part 10a includes a second rod 3121, which extends into the first rod 712. The second rod 3121 has a threaded hole 31211 and is sleeved on the outside of the drive shaft 62. The drive shaft 62 is a screw and meshes with the threaded hole 31211. Thus, the first rod 712 provides external protection for the transmission between the second rod 3121 and the screw. Under the protection of the first rod 712, moisture and dust are difficult to enter the position where the screw meshes with the threaded hole 31211, thereby making the transmission stable and reliable and improving the reliability of the transmission.

[0143] Combination Figures 12-16In 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 rotatably fitted around the inner ring 212. The knob ring 41 surrounds the outer ring 211 and is fixed to the outer ring 211. The bottom end plate 22a is connected to the inner end of the inner ring 212. The outer peripheral wall of the first rod 712 is provided with a rotation limiting protrusion 713. There are multiple rotation limiting protrusions 713, which are spaced apart along the circumference of the first rod 712. Multiple limiting grooves 2121 are formed on the inner ring 212, and the multiple limiting grooves 2121 correspond one-to-one with the multiple rotation limiting protrusions 713. The axial insertion fits together to achieve a limited rotation fit between the panel base 102 and the core part 10a. The core part 10a includes a knob bracket 31, which is an integrated structural component and includes a connecting section 312 extending into the inner ring 212. The connecting section 312 includes a second rod 3121 and a first buckle 3122. The first buckle 3122 is engaged and fixed with the inner ring 212. There are multiple first buckles 3122, which are spaced around the first rod 712. A clearance area 312a is defined between adjacent first buckles 3122. The multiple clearance areas 312a correspond to and avoid multiple limited rotation protrusions 713.

[0144] In the above technical solution, multiple limiting grooves 2121 and multiple limiting protrusions 713 are connected in a one-to-one manner along the axial direction, that is, the limiting protrusions 713 and the limiting grooves 2121 are connected at multiple points, which increases the stability and reliability of the limiting rotation. Compared to single-point or few-point engagement, multi-point engagement can better disperse the force, reducing the risk of loosening or damage to the inner ring 212 due to excessive local force. The first buckle 3122 is engaged with the inner ring 212, which fixes the knob bracket 31 and the inner ring 212 together to form a fixed core 10a. The engagement of the rotation limiting protrusion 713 with the limiting groove 2121 restricts the rotation of the core 10a, allowing the knob 201 to achieve linear translation and extension. Multiple avoidance areas 312a avoid multiple rotation limiting protrusions 713 one by one, so that the first buckle 3122 and the rotation limiting protrusion 713 can avoid interference in a limited space, and improve the overall structural compactness of the knob 201, reducing the volume and weight of the knob 201.

[0145] See Figure 17 In some embodiments, the panel component 1000 further includes a panel base 102, which is mounted on the inner side of the panel 101. The driver 202 is mounted on the knob 201 (i.e., the driver 202 is directly or indirectly fixedly connected to the knob 201), and the driver 202 is in a transmission engagement with the panel base 102 so as to reciprocate between the extended position and the retracted position relative to the panel 101 in sync with the knob 201.

[0146] In the above technical solution, the driver 202 is disposed on the knob 201 and cooperates with the panel base 102 located inside the panel 101 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 component 1000.

[0147] 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 moves by cooperating with the panel base 102 through a transmission mechanism such as gears and screws. 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 outside 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 22a 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 base 102 to realize the movement of the knob 201.

[0148] See Figure 17 In some embodiments, the panel base 102 includes a second ring 714 and a third ring 715, the third ring 715 being concentrically fitted with the second ring 714, and the outer peripheral edge of the bottom plate 22a having a fourth ring 22a1 extending toward the direction away from the panel 101. A third circuit board 203 and a driver 202 are provided on the side of the bottom plate 22a away from the panel 101, and both the third circuit board 203 and the driver 202 are located inside the fourth ring 22a1. The fourth ring 22a1 is movably fitted between the second ring 714 and the third ring 715 along the extension and retraction direction of the knob 201.

[0149] In the above technical solution, the outer peripheral edge of the bottom plate 22a has a fourth ring 22a1 extending in the direction away from the front panel 101. A third circuit board 203 and a driver 202 are provided on the side of the bottom plate 22a away from the front panel 101. The fourth ring 22a1 is fitted between the second ring 714 and the third ring 715. Thus, the third circuit board 203 and the driver 202 are located in the innermost ring 212 (second ring 714). The second ring 714, the third ring 715, and the fourth ring 22a1 protect the third circuit board 203 and the driver 202 in the innermost ring space. Moisture, dust, etc. are difficult to enter the innermost ring 212 (second ring 714) through the tortuous path formed by the third ring 715, the fourth ring 22a1, and the second ring 714 and cause damage to the third circuit board 203 and the driver 202, thereby improving the reliability of the reciprocating motion of the knob 201.

[0150] Combination Figures 12-16 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 to be rotatable relative to the core portion 10a. The rotating portion 10b includes a knob ring 41. The knob 201 includes a screen 51, which is located at the axial outer end of the knob ring 41 and is fixed relative to the core portion 10a. However, this is not a limitation. In other embodiments of this application, the screen 51 may also be designed to be fixed relative to the rotating portion 10b. The axial outer end of the knob ring 41 refers to the end of the knob 201 axially away from the interior of the panel 101.

[0151] In the above technical solution, the screen 51 is positioned at the outer axial end of the knob ring 41, allowing 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 positioned on the knob 201 of an air conditioner 10000, the screen 51 can display the currently set temperature value in real time when the user rotates the knob 201 to adjust the temperature. This allows the user to promptly understand whether the temperature adjustment operation using the knob 201 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. The type of screen 51 is not limited; it can be a pure display screen, a touch screen, or a voice-interactive screen, etc.

[0152] Combination Figures 12-16In some embodiments, the knob 201 includes an encoder 21 and a knob bracket 31. The encoder 21 includes an inner ring 212 and an outer ring 211. The outer ring 211 is rotatably sleeved on the outside of the inner ring 212. The knob ring 41 surrounds the outer ring 211 and engages with it. The knob bracket 31 is an integrated structural component and includes a support section 311 and a connecting section 312. The support section 311 and the bottom end plate 22a are respectively located on both axial sides of the inner ring 212. 12 is connected to the support section 311 and extends into the inner ring 212 and engages with the inner ring 212. The bottom plate 22a is engaged with the inner ring 212. The support section 311 defines a mounting groove 311a that opens in a direction away from the bottom plate 22a. The knob 201 includes a face cover 52. The screen 51 is located in the mounting groove 311a. The face cover 52 covers the side of the screen 51 away from the connecting section 312. The face cover 52 is connected to the knob bracket 31 or to the knob ring 41.

[0153] In the above technical solution, the screen 51 is located within the mounting groove 311a of the support section 311, which is a knob bracket 31. The knob bracket 31 is snapped together with the inner ring 212 to form a fixed, non-rotating core part 10a. Therefore, the screen 51 does not rotate when the knob 201 extends or retracts, which helps the user obtain the information displayed on the screen 51. For example, the screen 51 is used to display control information, and the screen 51 always faces the user, eliminating the need for the user to adjust the angle to view the content of the screen 51, thus improving the user experience.

[0154] The screen 51 is located within the mounting groove 311a of the support section 311, and the cover 52 is positioned on the side of the screen 51 furthest from the connecting section 312. Thus, the cover 52 and the mounting groove 311a provide excellent physical protection for the screen 51. In daily use, the cover 52 and the mounting groove 311a reduce damage from impacts, scratches, and other external forces, extending the lifespan of the screen 51. The screen 51's placement within the mounting groove 311a, for example, reduces light loss and also shields it from external light, minimizing interference. Consequently, the display on the screen 51 is clearer and brighter, allowing users to read the information even in bright environments.

[0155] Combination Figure 4In some embodiments, the panel component 1000 further includes a driver 202, which drives the knob 201 to reciprocate 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 outward 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.

[0156] 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.

[0157] Combination Figure 12 , Figure 13 and Figure 16In 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 base 102 includes a motor base 71, which is located inside the panel 101 and fixed relative to the panel 101. The motor base 71 is an integrated structural component and includes a mating section 712b. The mating section 712b includes a first rod 712 and a rotation limiting protrusion 713. A second rod 3121 extends into the first rod 712, and the rotation limiting protrusion 713 is located outside the first rod 712 and engages with the encoder fixing part 21b for rotation limiting.

[0158] In the above technical solution, the motor base 71 is an integrated structural component. The mating section 712b of the motor base 71 includes a first rod 712 and a rotation-limiting protrusion 713. The second rod 3121 extends into the first rod 712, forming an inner and outer guide fit, so that the knob 201 can move linearly relative to the panel 101. The rotation-limiting protrusion 713 engages 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 motor 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 712 and the rotation-limiting protrusion 713 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 motor 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.

[0159] Furthermore, since the rotation limiting protrusion 713 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.

[0160] In the embodiments of this application, the specific form of the rotation limiting protrusion 713 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 protrusion 713 is 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 protrusion 713 is constructed as a rotation limiting post. The shape of the rotation limiting sleeve limits the rotation of the encoder fixing part 21b.

[0161] Combination Figure 12 and Figure 14 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 712 and is engaged and fixed with the encoder fixing part 21b.

[0162] 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 712, forming 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.

[0163] 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 712, making reasonable use of space. While fulfilling the connection function, it will not interfere with the installation and movement of other components inside the knob 201. This makes the entire knob 201 structure more compact, which is beneficial for the miniaturization design of the knob 201.

[0164] Combination Figures 12-16In 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 712, and the multiple first buckles 3122 are engaged with the multiple retaining ribs 2122 in a one-to-one manner. The distance between adjacent first buckles 3122 is limited. The inner ring 212 has a clearance zone 312a; multiple limiting grooves 2121 are formed on the inner peripheral wall of the inner ring 212, which are spaced apart along the circumference. The multiple limiting grooves 2121 and multiple retaining ribs 2122 are alternately arranged. The rotation limiting protrusions 713 are formed as protrusions on the outer peripheral wall of the first rod 712. There are multiple rotation limiting protrusions 713, which are spaced apart along the circumference of the first rod 712. The multiple rotation limiting protrusions 713 are located in the multiple clearance zones 312a, and the multiple rotation limiting protrusions 713 and the multiple limiting grooves 2121 are matched one by one to limit rotation.

[0165] 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 engagement, enhancing 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 protrusions 713 are located in the multiple avoidance areas 312a in a one-to-one correspondence. That is, the multiple avoidance areas 312a avoid the multiple rotation limiting protrusions 713 in a one-to-one correspondence. The rotation limiting protrusions 713 need to cooperate with the limiting grooves 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 protrusions 713. Therefore, the inner ring 212 structure of the encoder 21 is relatively compact, which is conducive to the miniaturization of the knob 201.

[0166] In the above technical solution, multiple rotation-limiting protrusions 713 and multiple limiting grooves 2121 are inserted and matched one by one along the axial direction. That is, the rotation-limiting protrusions 713 and the limiting grooves 2121 are connected at multiple points, which increases the stability and reliability of rotation limitation. Compared with single-point or a few-point matching, multi-point matching can better disperse the force and reduce the risk of loosening of the fit or damage to the inner ring 212 due to excessive local force. In addition, the multi-point insertion matching method can limit 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.

[0167] In some embodiments, the first rod 712 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 712 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 712, 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.

[0168] In the above technical solution, the first rod 712 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 712 are tightly fitted together and guided in the axial direction of the first rod 712, 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.

[0169] 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 712, while preventing loosening due to excessive clearance, which would affect the reliability of the knob 201's movement. Simultaneously, it reduces friction between the first rod 712 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 and extending the service life of both rods.

[0170] 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 712 are guided and fitted together, the second rod 3121 can rotate relative to the first rod 712 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 protrusion 713 of the mating section 712b of the motor mount 71. This allows both the knob bracket 31 and the motor mount 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 motor mount 71 engages with the inner ring 212), thereby improving the ease of assembly of the knob 201.

[0171] For example, refer to Figures 13-15 The core part 10a includes a knob bracket 31, which is an integrated structural component and includes a connecting section 312 and a support section 311. The connecting section 312 includes a second rod 3121. The support section 311 is located at the axial outer end of the connecting section 312, that is, at the end near the outer side of the panel 101, and defines a mounting groove 311a that opens outward toward 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.

[0172] 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.

[0173] For example, combined Figure 13 and Figure 14 The knob 201 also includes a 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 engages with the support section 311.

[0174] In the above technical solution, the cover plate 521 is installed 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 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 cover 52 can also be set to be relatively fixed with the knob ring 41, which will not be elaborated here.

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.
