Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to a thermostat and an air conditioner. Background Art

[0002] Some air conditioners in the related art are equipped with a thermostat, which is usually mounted on a room wall to control the air conditioner. Typically, the thermostat has a sensor inside for sensing the ambient temperature, and a through-hole is provided in the thermostat housing. The sensor detects the indoor ambient temperature through the through-hole, allowing the thermostat to make logical controls based on the indoor ambient temperature, thereby adjusting the indoor temperature.

[0003] However, since the electrical components inside the thermostat generate heat during operation, the temperature value detected by the sensor cannot truly reflect the indoor ambient temperature, resulting in inaccurate sensor measurement results, which in turn affects the air conditioner's ability to regulate the indoor temperature. Summary of the Invention

[0004] The present application provides a thermostat and an air conditioner, which aim to improve the accuracy of sensor detection results, thereby facilitating improvement of the air conditioner's effect on regulating indoor temperature.

[0005] The specific technical solutions are as follows: An embodiment of the first aspect of the present application provides a temperature controller, which includes a shell assembly, a knob assembly, and a sensor. The knob assembly is connected to the shell assembly, and the knob assembly includes a knob cover that can rotate relative to the shell assembly. The knob cover is located outside the shell assembly, and the knob cover is formed with a receiving groove arranged in the direction of the shell assembly. The sensor includes a sensor body, and the sensor body is arranged in the receiving groove of the knob cover.

[0006] In the thermostat of the present application, the knob assembly includes a knob cover, which is located outside the housing assembly. The knob cover has a receiving groove formed in the knob cover, which faces the housing assembly. The sensor body is disposed within the receiving groove of the knob cover. Thus, the sensor body is located outside the housing assembly. Since the electrical components in the thermostat are typically located inside the housing assembly, the sensor body is relatively far away from the electrical components within the thermostat. This reduces the impact of heat generated by the electrical components on the sensor body, thereby improving the accuracy of the sensor's measurement results and, in turn, enhancing the air conditioner's ability to regulate indoor temperature.

[0007] In some embodiments, the housing assembly includes a shell and a front cover connected to the shell, the front cover includes a front cover body and a mounting base connected to the front cover body, the knob assembly is mounted on the mounting base, a partial structure of the mounting base is located in the accommodating groove, and the sensor is mounted on the mounting base.

[0008] The housing and front cover can jointly define a mounting cavity, within which the electrical components of the thermostat are disposed, thereby protecting the electrical components from the housing and front cover. The front cover includes a front cover body and a mounting base, with the knob assembly mounted on the mounting base, thereby ensuring stable mounting of the knob assembly and the front cover. When the knob assembly is mounted on the mounting base, a portion of the mounting base is located within the receiving groove of the knob cover, and the sensor is mounted on the mounting base. This arrangement, while ensuring stable sensor mounting, allows the sensor body to be located within the receiving groove of the knob cover, thereby reducing the impact of heat generated by the electrical components within the thermostat on the sensor body. Furthermore, the knob cover is a movable component, while the mounting base is fixed relative to the front cover body and is a non-movable component. Mounting the sensor on the non-movable mounting base is more conducive to improving the sensor's operational stability than mounting the sensor on the knob cover.

[0009] In some embodiments, the front cover body is provided with a mounting opening, the mounting base is passed through the mounting opening, and the mounting base is constructed as a cylindrical structure; the mounting base is formed with a wire threading hole extending along a first direction, and the wire threading hole is provided on the mounting base along the first direction, and the first direction is parallel to the axis of the cylindrical structure; the temperature controller also includes a control main board, which is provided inside the shell assembly, and the sensor body is located at one end of the mounting base outside the shell assembly, and the sensor also includes a signal line, one end of the signal line is connected to the sensor body, the signal line is passed through the wire threading hole, and the other end of the signal line extends to the inside of the shell assembly and is connected to the control main board.

[0010] The sensor has a signal line, one end of which is connected to the sensor body, and the other end extends into the interior of the housing assembly and connects to the thermostat's control board, allowing the temperature information obtained by the sensor body to be transmitted to the control board. The mounting base is constructed as a cylindrical structure, the inner cavity of which can accommodate the structure of the knob assembly, thereby enabling the installation of the knob assembly. On this basis, the sensor body is located at the end of the mounting base that is located outside the housing assembly, and the signal line is inserted through the threading hole of the mounting base. When the other end of the signal line is connected to the control board, the sensor body can be retained at the end of the mounting base, thereby achieving the installation and fixation of the sensor body.

[0011] In addition, the front cover body is provided with a mounting opening, and the mounting base is passed through the mounting opening, so that a coupling relationship can be established more easily between the knob assembly and the control main board located inside the shell assembly, thereby realizing the control function of the knob assembly.

[0012] In some embodiments, the number of the signal lines is two, the number of the threading holes is two, and each signal line is passed through a corresponding threading hole.

[0013] Such an arrangement makes it difficult for the sensor body to rotate relative to the mounting base, so that the sensor body can be more firmly held on the end of the mounting base, thereby improving the stability of the installation.

[0014] In some embodiments, the control main board is connected to the front cover body.

[0015] The control main board is connected to the front cover body. After the front cover is assembled with the shell, the control main board can be firmly installed inside the shell assembly.

[0016] In some embodiments, the thermostat further includes a power board, which is electrically connected to the control main board. The power board is located inside the housing assembly, and the power board is connected to the shell.

[0017] The power board is connected to the shell, so that after the front cover and the shell are assembled, the power board can be firmly installed inside the housing assembly.

[0018] In some embodiments, the knob cover is provided with a plurality of ventilation holes, and the ventilation holes are connected to the receiving groove.

[0019] The knob cover is provided with a plurality of ventilation holes, through which the receiving groove of the knob cover can be connected with the indoor environment. In this way, the temperature in the receiving groove can be kept consistent with the indoor environment temperature, so that the temperature detected by the sensor body is the indoor environment temperature.

[0020] In some embodiments, the shell assembly includes a shell and a front cover connected to the shell, the front cover includes a front cover body and a mounting base connected to the front cover body, part of the structure of the mounting base is located in the accommodating groove, and the mounting base is constructed as a cylindrical structure; the knob assembly also includes a knob support, one end of the knob support is connected to the knob cover body, part of the structure of the knob support is located inside the mounting base, a limiting step is formed inside the mounting base, and a limiting buckle is formed at the other end of the knob support, and the limiting buckle abuts against the limiting step.

[0021] The knob cover is mounted on the mounting base via the knob support through the abutment between the stop buckle and the stop step. Furthermore, the abutment between the stop buckle and the stop step does not restrict the rotational freedom of the rotation support relative to the mounting base, thereby allowing the knob cover to rotate relative to the mounting base, allowing the user to interact with the thermostat by rotating the knob cover.

[0022] In some embodiments, the knob assembly further includes a first spring and a spring limiter, wherein the spring limiter is located inside the mounting base and connected to the mounting base, one end of the first spring abuts against the knob cover, and the other end of the first spring abuts against the spring limiter.

[0023] The spring limiter is connected to the mounting base, one end of the first spring is in contact with the knob cover, and the other end is in contact with the spring limiter. Under the elastic action of the first spring, the limit buckle can be tightly in contact with the limit step, which can provide a certain damping effect for the rotation of the knob cover. On the one hand, it can reduce the chance of accidental rotation of the knob cover. On the other hand, it can provide the user with a better feel when turning the knob cover, which is conducive to preventing the knob cover from over-rotating.

[0024] In some embodiments, the knob cover is formed with a first positioning column, the first positioning column is located in the accommodating cavity, the spring limiter is formed with a second positioning column, and the first spring is sleeved on the first positioning column and the second positioning column.

[0025] Such an arrangement is beneficial for preventing the first spring from being offset, thereby improving the working stability of the first spring.

[0026] In some embodiments, the knob support is formed with a receiving groove, and the knob assembly also includes a magnet, which is connected to the knob support and located in the receiving groove; the temperature controller also includes a control mainboard, which is arranged inside the shell assembly, and the control mainboard is provided with a magnetic control chip, and the magnet and the magnetic control chip are arranged relative to each other along a first direction, and the first direction is parallel to the axis of the cylindrical structure.

[0027] When the user turns the knob cover, the knob cover drives the magnet to rotate via the knob support. This rotation of the magnet causes a change in the magnetic field. The magnetic control chip can identify this magnetic field change and output corresponding control instructions based on the magnetic field change, thereby achieving the corresponding control function. By placing the magnet in the receiving groove of the knob support and the magnetic control chip on the control motherboard, the knob assembly can achieve its control function without physical contact or connection with the control motherboard. This facilitates a relatively simple and compact knob assembly structure, thereby reducing the size of the knob assembly.

[0028] In some embodiments, the knob support is formed with a receiving groove, and the knob assembly also includes a damping structure, and the damping structure includes a support frame and a second spring, at least a portion of the support frame is located in the receiving groove, one end of the support frame abuts against the knob support, and the other end of the support frame is connected to the second spring, and the end of the second spring away from the support frame abuts against the inner wall of the mounting base.

[0029] One end of the support frame abuts the knob support, and the other end of the support frame is connected to a second spring. The end of the second spring, away from the support frame, abuts the inner wall of the mounting base. This arrangement ensures that when the knob support rotates relative to the mounting base, the user needs to overcome the friction between the second spring and the mounting base. This provides a certain degree of damping for the rotation of the knob cover. This reduces the chance of accidental rotation of the knob cover and provides a better feel for the user when turning the knob cover, helping to prevent over-rotation of the knob cover.

[0030] In some embodiments, the support frame includes a frame body and a limit block connected to the frame body, the second spring is connected to the frame body, the limit block is located at one end of the frame body away from the second spring, the knob support forms a limit slot, the limit block is arranged in the limit slot, and the end of the frame body close to the limit block abuts against the knob support.

[0031] The limiting block is located in the limiting groove of the knob support, which can prevent the support frame from positional displacement and maintain a stable abutment relationship between the frame body and the knob support, thereby improving the working stability of the damping structure.

[0032] In some embodiments, the front cover body is provided with a mounting opening, the mounting base is passed through the mounting opening, the mounting base is constructed as a cylindrical structure, and there is a gap between the mounting base and the inner wall of the mounting opening; the temperature controller also includes a light guide ring, the light guide ring is sleeved on the mounting base and abuts against the front cover body, the light guide ring and the gap are arranged relative to each other along a first direction, and the first direction is parallel to the axis of the cylindrical structure; the temperature controller also includes a control main board, the control main board is arranged inside the shell assembly, the control main board is provided with a light source, and the light emitted by the light source can be received by the light guide ring through the gap.

[0033] The light source is configured to provide light with different lighting effects. This allows the light source to emit light with different lighting effects as the user adjusts input information by turning the knob cover. The light guide ring illuminates upon receiving light from the light source, and the color and brightness of the light guide ring change accordingly with the light effect of the light source. As the user uses the knob assembly, the light guide ring illuminates and changes color and brightness, providing control feedback to the user in the form of light, thereby enhancing the user experience.

[0034] In some embodiments, the light guide ring includes an annular body and a snap-fit ​​portion connecting the annular body, and the snap-fit ​​portion passes through the gap and abuts against the inner side surface of the front cover body.

[0035] When installing the light guide ring, the light guide ring can be first placed on the mounting base, and the snap portion can be inserted into the gap between the mounting base and the inner wall of the mounting opening. Then, the light guide ring can be moved along the mounting base toward the front cover body until the snap portion engages with the inner side surface of the front cover body. At this time, the snap portion and the inner side surface of the front cover body form an abutting relationship, thereby achieving stable installation of the light guide ring. In addition, the above installation method has the advantage of convenient installation, which is conducive to improving assembly efficiency.

[0036] An embodiment of the second aspect of the present application provides an air conditioner, which includes the thermostat in any of the above embodiments.

[0037] In an air conditioner according to an embodiment of the present application, the thermostat knob assembly includes a knob cover, which is located outside the housing assembly. The knob cover has a receiving groove formed therein, facing the housing assembly. The sensor body is disposed within the receiving groove of the knob cover. Thus, the sensor body is located outside the housing assembly. Since the electrical components of a thermostat are typically located inside the housing assembly, the sensor body is relatively far away from the electrical components within the thermostat. This reduces the effect of heat generated by the electrical components on the sensor body, thereby improving the accuracy of the sensor's measurement results and, in turn, facilitating an improvement in the air conditioner's ability to regulate indoor temperature.

[0042] The following will clearly and thoroughly describe the technical solutions in this application in conjunction with the accompanying drawings. In the description of the embodiments of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of this application, "multiple" means two or more than two.

[0043] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to imply or suggest relative importance or implicitly indicate the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0044] like Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 As shown, an embodiment of the first aspect of the present application provides a thermostat 10, which includes a housing assembly 200, a knob assembly 100, and a sensor 300. The knob assembly 100 is connected to the housing assembly 200, and the knob assembly 100 includes a knob cover 110 that is rotatable relative to the housing assembly 200. The knob cover 110 is located outside the housing assembly 200 and has a receiving groove 111 formed in the knob cover 110, which is arranged in a direction facing the housing assembly 200. The sensor 300 includes a sensor body 310, which is disposed in the receiving groove 111 of the knob cover 110.

[0045] Specifically, the thermostat 10 may be a temperature control device such as a wired controller or a centralized controller.

[0046] The housing assembly 200 is the housing portion of the thermostat 10 and is used to protect the electrical components inside the thermostat 10 (such as the control mainboard 400, the power board 500, etc.). The knob assembly 100 is the control component of the thermostat 10. The user can interact with the thermostat 10 through the knob assembly 100 to input control commands. For example, the user can input a target temperature value through the knob assembly 100. Once the target temperature value is confirmed, the thermostat 10 can control the air conditioner, thereby adjusting the indoor ambient temperature based on the target temperature value. The knob assembly 100 includes a knob cover 110 that is rotatable relative to the housing assembly 200. The knob cover 110 is the structure that the user directly contacts and performs control actions when interacting with the thermostat 10. The user can apply torque to the knob cover 110 to rotate it, thereby adjusting the input information (for example, adjusting the target temperature value).

[0047] The sensor 300 may be a temperature sensor or a temperature and humidity sensor, and is used to detect the indoor ambient temperature. The sensor body 310 is the main part of the sensor 300, and the sensor body 310 has the function of sensing the ambient temperature.

[0048] In the thermostat 10 of the embodiment of the present application, the knob assembly 100 includes a knob cover 110. The knob cover 110 is located outside the housing assembly 200. The knob cover 110 is formed with a receiving groove 111 facing the housing assembly 200. The sensor body 310 is disposed in the receiving groove 111 of the knob cover 110. Thus, the sensor body 310 is located outside the housing assembly 200. Since the electrical components in the thermostat 10 are generally located inside the housing assembly 200, the sensor body 310 is relatively far away from the electrical components within the thermostat 10. This reduces the effect of heat generated by the electrical components on the sensor body 310, thereby improving the accuracy of the measurement results of the sensor 300 and further improving the indoor temperature regulation effect of the air conditioner.

[0049] like Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 As shown, in some embodiments, the housing assembly 200 includes a shell 210 and a front cover 220 connected to the shell 210, the front cover 220 includes a front cover body 221 and a mounting base 223 connected to the front cover body 221, the knob assembly 100 is mounted on the mounting base 223, a partial structure of the mounting base 223 is located in the accommodating groove 111, and the sensor 300 is mounted on the mounting base 223.

[0050] The housing 210 and the front cover 220 can collectively define a mounting cavity, within which the electrical components of the thermostat 10 are mounted, thereby protecting them from the effects of the housing 210 and the front cover 220. When the thermostat 10 is mounted on a wall, the housing 210 can be partially or entirely recessed into the wall to minimize protrusion and enhance aesthetics. The front cover 220 can also partially or entirely protrude from the wall surface. When the thermostat 10 is mounted on a wall, the front cover 220 forms the visible exterior surface of the thermostat 10.

[0051] The front cover 220 includes a front cover body 221 and a mounting base 223. The knob assembly 100 is mounted on the mounting base 223, thereby ensuring stable installation of the knob assembly 100 and the front cover 220. When the knob assembly 100 is mounted on the mounting base 223, a portion of the mounting base 223 is located within the receiving groove 111 of the knob cover 110, and the sensor 300 is mounted on the mounting base 223. This arrangement not only ensures stable installation of the sensor 300, but also allows the sensor body 310 to be located within the receiving groove 111 of the knob cover 110, thereby reducing the impact of heat generated by the internal electrical components of the thermostat 10 on the sensor body 310. On the other hand, the knob cover 110 is a movable component, while the mounting base 223 is fixed relative to the front cover body 221 and is an immovable component. Installing the sensor 300 on the immovable mounting base 223 is more conducive to improving the working stability of the sensor 300 than installing the sensor 300 on the knob cover 110.

[0052] like Figure 4 、 Figure 5 as well as Figure 6 As shown, in some embodiments, the front cover body 221 is provided with a mounting opening 222, and the mounting base 223 is provided through the mounting opening 222, and the mounting base 223 is configured as a cylindrical structure. The mounting base 223 is formed with a threading hole 224 extending along a first direction, and the threading hole 224 is provided through the mounting base 223 along the first direction, and the first direction is parallel to the axis of the cylindrical structure. The thermostat 10 also includes a control mainboard 400, which is provided inside the housing assembly 200. The sensor body 310 is located at one end of the mounting base 223 that is located outside the housing assembly 200. The sensor 300 also includes a signal line 320, one end of the signal line 320 is connected to the sensor body 310, the signal line 320 is provided through the threading hole 224, and the other end of the signal line 320 extends into the interior of the housing assembly 200 and is connected to the control mainboard 400.

[0053] The sensor 300 has a signal line 320, one end of which is connected to the sensor body 310, and the other end extends to the interior of the housing assembly 200 and is connected to the control motherboard 400 of the thermostat 10, so that the temperature information obtained by the sensor body 310 can be transmitted to the control motherboard 400.

[0054] The mounting base 223 is constructed as a cylindrical structure, the inner cavity of which can accommodate the components of the knob assembly 100, thereby enabling installation of the knob assembly 100. Based on this, the sensor body 310 is located at the end of the mounting base 223 that is located outside the housing assembly 200. The signal line 320 is inserted through the threading hole 224 of the mounting base 223. When the other end of the signal line 320 is connected to the control motherboard 400, the sensor body 310 can be retained at the end of the mounting base 223, thereby achieving installation and fixation of the sensor body 310.

[0055] In addition, the front cover body 221 is provided with a mounting opening 222, and the mounting base 223 is passed through the mounting opening 222, so that a coupling relationship can be established more easily between the knob assembly 100 and the control main board 400 located inside the shell assembly 200, thereby realizing the control function of the knob assembly 100.

[0056] like Figure 6 As shown, in one embodiment, there are two signal lines 320 and two threading holes 224, with each signal line 320 being passed through a corresponding threading hole 224. This arrangement prevents the sensor body 310 from rotating relative to the mounting base 223, allowing the sensor body 310 to be more firmly secured to the end of the mounting base 223, thereby improving installation stability.

[0057] In one embodiment, the sensor body 310 is fixed to the mounting base 223 by gluing, thereby further improving the mounting firmness of the sensor body 310 and further facilitating the improvement of the working stability of the sensor 300 .

[0058] like Figure 1 As shown, in one embodiment, the control main board 400 is connected to the front cover body 221 .

[0059] For example, the control main board 400 and the front cover body 221 may be connected by screws, snaps, or the like.

[0060] The control main board 400 is connected to the front cover main body 221 . After the front cover 220 and the shell 210 are assembled, the control main board 400 can be stably installed inside the housing assembly 200 .

[0061] like Figure 1As shown, in one embodiment, the thermostat 10 further includes a power board 500, which is electrically connected to the control main board 400 and can provide power to the control main board 400. The power board 500 is located inside the housing assembly 200 and is connected to the housing 210.

[0062] For example, the power board 500 and the housing 210 may be connected by screws, snaps, or the like.

[0063] The power board 500 is connected to the housing 210 , so that after the front cover 220 and the housing 210 are assembled, the power board 500 can be stably installed inside the housing assembly 200 .

[0064] In some embodiments, the knob cover 110 is provided with a plurality of ventilation holes, which are communicated with the receiving slot 111. The ventilation holes can be provided on the end wall and / or side wall of the knob cover 110.

[0065] The knob cover 110 is provided with a plurality of ventilation holes, through which the receiving groove 111 of the knob cover 110 can be connected to the indoor environment. In this way, the temperature in the receiving groove 111 can be kept consistent with the indoor environment temperature, so that the temperature detected by the sensor body 310 is the indoor environment temperature.

[0066] Furthermore, the diameter of the ventilation hole is less than 1 mm, so that the receiving groove 111 can be connected to the indoor environment. At the same time, since the diameter of the ventilation hole is small, it is helpful to prevent dirt and foreign matter from entering the receiving groove 111 of the knob cover 110.

[0067] In one embodiment, the diameter of the ventilation holes is greater than or equal to 1 μm and less than or equal to 10 μm. This arrangement allows the receiving tank 111 to communicate with the indoor environment, so that the temperature inside the receiving tank 111 is consistent with the indoor environment temperature. At the same time, it can also block smaller particles and dust, thereby helping to keep the receiving tank 111 clean.

[0068] like Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4As shown, in some embodiments, the housing assembly 200 includes a housing 210 and a front cover 220 connected to the housing 210. The front cover 220 includes a front cover body 221 and a mounting base 223 connected to the front cover body 221. Part of the mounting base 223 is located in the receiving groove 111, and the mounting base 223 is constructed as a cylindrical structure. The knob assembly 100 also includes a knob support 120. One end of the knob support 120 is connected to the knob cover 110, and part of the knob support 120 is located inside the mounting base 223. A limiting step 2231 is formed inside the mounting base 223, and a limiting buckle 121 is formed at the other end of the knob support 120. The limiting buckle 121 abuts against the limiting step 2231.

[0069] One end of the knob support 120 is connected to the knob cover 110, and the other end of the knob support 120 forms a limit buckle 121, which abuts against a limit step 2231 within the mounting base 223. The abutment between the limit buckle 121 and the limit step 2231 allows the knob cover 110 to be mounted on the mounting base 223 via the knob support 120. Furthermore, the abutment between the limit buckle 121 and the limit step 2231 does not restrict the rotational freedom of the rotary support relative to the mounting base 223. Thus, the knob cover 110 can rotate relative to the mounting base 223, allowing the user to interact with the thermostat 10 by rotating the knob cover 110.

[0070] Exemplarily, the knob support 120 and the knob cover 110 may be connected by screws, snaps, etc., and this application does not impose any limitation on this.

[0071] like Figure 2 、 Figure 4 As shown, in one embodiment, the knob assembly 100 also includes a first spring 130 and a spring limiter 140. The spring limiter 140 is located inside the mounting base 223 and is connected to the mounting base 223. One end of the first spring 130 abuts against the knob cover 110, and the other end of the first spring 130 abuts against the spring limiter 140.

[0072] For example, the spring limiter 140 may be connected to the mounting base 223 by screws, clamping, or the like.

[0073] The spring limiter 140 is connected to the mounting base 223. One end of the first spring 130 abuts against the knob cover 110, and the other end abuts against the spring limiter 140. Under the elastic action of the first spring 130, the limit buckle 121 can be tightly abutted against the limit step 2231, which can provide a certain damping effect for the rotation of the knob cover 110. On the one hand, it can reduce the chance of accidental rotation of the knob cover 110. On the other hand, it can provide the user with a better feel when rotating the knob cover 110, which is conducive to preventing the knob cover 110 from rotating too far.

[0074] like Figure 2 、 Figure 4 As shown, in one embodiment, the knob cover 110 is formed with a first positioning post 112, which is located in the accommodating cavity. The spring stopper 140 is formed with a second positioning post 141, and the first spring 130 is sleeved between the first positioning post 112 and the second positioning post 141. This arrangement helps prevent positional deviation of the first spring 130, thereby improving the working stability of the first spring 130.

[0075] like Figure 2 、 Figure 4 As shown, in one embodiment, the knob support 120 is formed with a receiving groove 122, and the knob assembly 100 further includes a magnet 150, which is connected to the knob support 120 and located in the receiving groove 122. The thermostat 10 further includes a control mainboard 400, which is disposed inside the housing assembly 200 and is provided with a magnetron chip. The magnet 150 and the magnetron chip are disposed opposite each other along a first direction, which is parallel to the axis of the cylindrical structure.

[0076] When the user rotates the knob cover 110, the knob cover 110 drives the magnet 150 to rotate via the knob support 120. The rotation of the magnet 150 causes a change in the magnetic field. The magnetic control chip can identify the change in the magnetic field and output corresponding control instructions based on the change in the magnetic field, thereby realizing the corresponding control function. By disposing the magnet 150 in the receiving groove 122 of the knob support 120 and the magnetic control chip on the control mainboard 400, the knob assembly 100 can realize the control function without the knob assembly 100 having to establish physical contact or physical connection with the control mainboard 400. This facilitates the relatively simple structure of the knob assembly 100 and the compact layout of the knob assembly 100, thereby facilitating a reduction in the size of the knob assembly 100.

[0077] like Figure 2 、 Figure 4As shown, in one embodiment, the knob support 120 is formed with a receiving groove 122, and the knob assembly 100 also includes a damping structure 160, the damping structure 160 includes a support frame 161 and a second spring 162, at least a portion of the support frame 161 is located in the receiving groove 122, one end of the support frame 161 abuts against the knob support 120, and the other end of the support frame 161 is connected to the second spring 162, and the end of the second spring 162 away from the support frame 161 abuts against the inner wall of the mounting base 223.

[0078] One end of the support frame 161 abuts against the knob support 120, and the other end of the support frame 161 is connected to the second spring 162. The end of the second spring 162 away from the support frame 161 abuts against the inner wall of the mounting base 223. This arrangement ensures that when the knob support 120 rotates relative to the mounting base 223, the user needs to overcome the friction between the second spring 162 and the mounting base 223. This provides a certain degree of damping for the rotation of the knob cover 110. On the one hand, this can reduce the probability of accidental rotation of the knob cover 110, and on the other hand, it can provide the user with a better feel when rotating the knob cover 110, which helps prevent the knob cover 110 from being over-rotated.

[0079] like Figure 2 As shown, in one embodiment, the support frame 161 includes a frame body 1611 and a limit block 1612 connected to the frame body 1611, the second spring 162 is connected to the frame body 1611, the limit block 1612 is located at one end of the frame body 1611 away from the second spring 162, the knob support 120 forms a limit groove 123, the limit block 1612 is arranged in the limit groove 123, and the end of the frame body 1611 close to the limit block 1612 abuts against the knob support 120.

[0080] The limit block 1612 is located in the limit groove 123 of the knob support 120, so that the support frame 161 can be prevented from positional displacement and a stable abutment relationship can be maintained between the frame body 1611 and the knob support 120, thereby improving the working stability of the damping structure 160.

[0081] like Figure 1 、 Figure 2As shown, in one embodiment, the front cover body 221 is provided with a mounting opening 222, and the mounting base 223 is provided through the mounting opening 222. The mounting base 223 is constructed as a cylindrical structure, and a gap is defined between the mounting base 223 and the inner wall of the mounting opening 222. The thermostat 10 also includes a light guide ring 600, which is sleeved on the mounting base 223 and abuts the front cover body 221. The light guide ring 600 is arranged relative to the gap along a first direction, which is parallel to the axis of the cylindrical structure. The thermostat 10 also includes a control mainboard 400, which is disposed within the housing assembly 200. The control mainboard 400 is provided with a light source, and light emitted by the light source can be received by the light guide ring 600 through the gap.

[0082] The light source is configured to provide light with different lighting effects. For example, the light source can emit light of different colors or different intensities. In this way, as the user adjusts the input information by rotating the knob cover 110, the light source can emit light with different lighting effects. For example, different intensities or colors of light can be matched according to the input target temperature value.

[0083] The light guide ring 600 can illuminate when it receives light from a light source, and the color and brightness of the light guide ring 600 can change accordingly with the light effect of the light source. In this way, when the user uses the knob assembly 100, the light guide ring 600 can illuminate and change color and brightness, thereby providing the user with control feedback in the form of light, thereby improving the user experience.

[0084] Furthermore, the light guide ring 600 may be made of a light-uniform material. Thus, when the light guide ring 600 receives light emitted by a light source, the light guide ring 600 may emit uniform and relatively soft light, thereby improving user experience.

[0085] like Figure 2 As shown, in one embodiment, the light guide ring 600 includes an annular body 610 and a snap-fit ​​portion 620 connected to the annular body 610 . The snap-fit ​​portion 620 passes through the gap and abuts against the inner side surface of the front cover body 221 .

[0086] When installing the light guide ring 600, the light guide ring 600 can be first placed on the mounting base 223, and the snap-fit ​​portion 620 can be inserted into the gap between the mounting base 223 and the inner wall of the mounting opening 222. The light guide ring 600 can then be moved along the mounting base 223 toward the front cover body 221 until the snap-fit ​​portion 620 engages with the inner side surface of the front cover body 221. At this point, the snap-fit ​​portion 620 and the inner side surface of the front cover body 221 form an abutting relationship, thereby achieving stable installation of the light guide ring 600. In addition, the above-mentioned installation method has the advantage of convenient installation, which is conducive to improving assembly efficiency.

[0087] An embodiment of the second aspect of the present application provides an air conditioner, which includes the thermostat 10 in any of the above embodiments.

[0088] In the air conditioner of the embodiment of the present application, the knob assembly 100 of the thermostat 10 includes a knob cover 110. The knob cover 110 is located outside the housing assembly 200. The knob cover 110 is formed with a receiving groove 111 facing the housing assembly 200. The sensor body 310 is disposed in the receiving groove 111 of the knob cover 110. Thus, the sensor body 310 is located outside the housing assembly 200. Since the electrical components in the thermostat 10 are generally located inside the housing assembly 200, the sensor body 310 is relatively far away from the electrical components inside the thermostat 10. This can reduce the impact of heat generated by the electrical components on the sensor body 310, thereby improving the accuracy of the measurement results of the sensor 300, and further facilitating the improvement of the indoor temperature regulation effect of the air conditioner.

[0089] The above content is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
