With continued reference to fig. 2 and 4, the display panel assembly 20 includes a display panel 21 and a display panel circuit board 22.

The display screen 21 may be adjacent to the lower surface of the panel 10 or may be spaced from the lower surface of the panel 10. The display screen 21 includes a first display area 211 and a second display area 212, and the first display area 211 and the second display area 212 may be configured to display different contents, for example, the first display area 211 is used for displaying an operating temperature or an operating time set by the home appliance 1000, the second display area 212 is used for displaying an operating mode of the home appliance 1000, or the second display area 212 is used for displaying an operating temperature or an operating time set by the home appliance 1000, and the first display area 211 is used for displaying an operating mode of the home appliance 1000. And is not particularly limited herein.

The display screen circuit board 22 may be located below the display screen 21, the display screen circuit board 22 is electrically connected to the display screen 21, and the display screen circuit board 22 is configured to provide power to the display screen 21 and transmit a control signal to the display screen 21 to control the display of the display screen 21.

In the present embodiment, the display screen 21 is a touch display screen, which includes but is not limited to a touch display screen such as a liquid crystal display screen, an OLED display screen, and an LED display screen. The user can perform a touch operation on the touch display screen to obtain an operation parameter or an operation mode of the household appliance 1000, and the display screen 21 can display various parameters and/or operation modes of the household appliance 1000 during operation. For example, taking the household appliance 1000 as an oven as an example, the user can set the operation time, the operation temperature, the operation mode, and the like of the oven by performing a touch operation on the touch display screen. In addition, the display screen 21 may display other contents such as the current operation mode and the current time. Of course, it is understood that the household appliance 1000 according to the embodiment of the present invention may also be other household appliances 1000, such as a microwave oven, a dishwasher, a disinfection cabinet, and the like, and is not limited in particular. In addition, in the present embodiment, the user can also control the display content of the display screen 21 and set various parameters and operation modes of the household appliance 1000 during operation, such as operating temperature, time, power, and the like, through the input component 30.

Referring to fig. 2, 4 and 5, the input module 30 is mounted on the upper surface of the panel 10. The orthographic projection of the input assembly 30 on the panel 10 at least partially overlaps the orthographic projection of the display screen assembly 20 on the panel 10, the display screen assembly 20 being capable of displaying through the panel 10 and the input assembly 30.

Specifically, the first display area 211 can be displayed through the first window 101 and the input element 30 corresponding to the panel 10, and the second display area 212 is located outside the range of the input element 30 and can be directly displayed through the second window 102 corresponding to the panel 10. The interaction component 100 is configured to control at least the display content of the first display region 211 using the input component 30. Specifically, referring to fig. 4, the input assembly 30 is formed with a first through hole 310, the first through hole 310 corresponds to the

first display regions

211 and 101 of the display screen 21, and an orthogonal projection of the first through hole 310 on the panel 10 coincides with an orthogonal projection of the first display region 211 on the panel 10. The first display region 211 is displayed through the first through hole 310. It is understood that in other embodiments, the orthographic projection of the first through hole 310 on the panel 10 may be larger than the orthographic projection of the first display region 211 on the panel 10, or the orthographic projection of the first through hole 310 on the panel 10 may be smaller than the orthographic projection of the first display region 211 on the panel 10.

In this way, since the orthographic projection of the input assembly 30 on the panel 10 at least partially overlaps the orthographic projection of the display screen assembly 20 on the panel 10, the occupied space of the display screen assembly 20 and the input assembly 30, especially the space in the left-right direction, can be reduced), and the overall sense of the interactive assembly 100 can be improved, and an alternative interactive process can be provided between the display screen assembly 20 and the input assembly 30, thereby improving the user experience.

In this embodiment, in order to improve the overall aesthetic appearance of the interactive assembly 100, black or other color ink may be coated on the upper surface and/or the lower surface of the panel 10 to form the first window 101 corresponding to the first display region 211 and the second window 102 corresponding to the second display region 212, that is, the ink is coated on the region outside the first window 101 and the second window 102, and the first window 101 and the second window 102 are kept transparent. Alternatively, the first window 101 and the second window 102 may be formed by directly forming two through holes in the panel 10.

Referring to fig. 2, 4 to 8 together, in the present embodiment, the input assembly 30 includes a knob assembly 31. The knob assembly 31 is formed with a first through hole 310, and the knob assembly 31 includes a first housing 311, a second housing 312, a mounting ring 313, an induction ring 314, an adhesive member 315, and a decoration cover 316. The middle parts of the first housing 311, the second housing 312, the mounting ring 313, the adhesive 315 and the decoration cover 316 are hollowed out, so that the knob assembly 31 is formed with a first through hole 310 for displaying the first display area 211 of the display screen 21.

The knob assembly 31 is substantially annular in shape as a whole. Referring to fig. 5, 9 and 10, the first housing 311 is substantially in the shape of a circular cylinder, and the first housing 311 may be made of plastic or metal. First casing 311 includes roof 3111 and connects inner wall 3112 and outer wall 3113 of roof 3111, and roof 3111, inner wall 3112 and outer wall 3113 enclose into mounting groove 3114 jointly, and inner wall 3112 of first casing 311 is formed with first buckle portion 3115 and second buckle portion 3116, and first buckle portion 3115 extends to the outer wall 3113 direction of keeping away from first casing 311 along inner wall 3112, and second buckle portion 3116 extends to the outer wall 3113 direction that is close to first casing 311 along inner wall 3112.

Referring to fig. 10 and 11, in the present embodiment, the number of the first latch portion 3115 and the second latch portion 3116 is four, four first latch portions 3115 are uniformly spaced along the circumferential direction of the knob assembly 31, and four second latch portions 3116 are uniformly spaced along the circumferential direction of the knob assembly 31. First latch portion 3115 and second latch portion 3116 are also provided at an interval, so that a fastening force can be provided to prevent the components from falling off. It is understood that in other embodiments, the number of the first and

second latch portions

3115 and 3116 may be less than four or more than 4, for example, at least two first latch portions 3115 and at least two second latch portions 3116.

Referring to fig. 5 and 7, the second housing 312 may be made of plastic or metal. The second housing 312 is mounted inside the first housing 311, and the first housing 311 and the second housing 312 are relatively rotatably connected. Referring to fig. 7, a locking groove 3121 is formed at the bottom of the second housing 312, and the locking groove 3121 is connected to the first locking portion 3115 to connect the second housing 312 and the first housing 311. In this way, the second housing 312 can be compactly and stably connected to the first housing 311 by the engagement connection of the first latch portion 3115 and the latch slot 3121, so that the second housing 312 is not easily separated from the first housing 311 to cause the knob assembly 31 to malfunction. In this embodiment, the slot 3121 is a continuous annular slot, so that when the first housing 311 and the second housing 312 are connected, the first housing 311 and the second housing 312 can continuously rotate forward and backward by 360 degrees. It will be appreciated that in other embodiments, the slot 3121 may be an intermittent annular slot, in which case the relative rotation of the first housing 311 and the second housing 312 would be limited to a certain range.

Further, referring to fig. 5, the first latch portion 3115 is in planar contact with the slot 3121, so that the first housing 311 and the second housing 312 can rotate relatively smoothly.

Referring to fig. 9 and 10, the sensor ring 314 is mounted in the mounting groove 3114 of the first housing 311, and the second latch portion 3116 latches the sensor ring 314 to fix the sensor ring 314 in the mounting groove 3114 (the arrow in fig. 9 indicates the mounting direction of the sensor ring 314). In this way, the second latch portion 3116 can stably latch the inductor ring 314 in the mounting groove 3114, so that the inductor ring 314 can rotate relative to the second housing 312 following the first housing 311.

In the present embodiment, the second housing 312 is fixedly attached to the panel 10, and the first housing 311 is rotatable with respect to the second housing 312. That is, in the present embodiment, the second housing 312 is fixed on the panel 10, and the first housing 311 and the induction ring 314 installed in the first housing 311 can rotate relative to the second housing 312, so that the user can rotate the knob assembly 31 conveniently.

It is understood that in other embodiments, the sensor ring 314 may be fixedly mounted on the second housing 312, the first housing 311 is fixedly mounted on the panel 10, and the second housing 312 and the sensor ring 314 can rotate relative to the first housing 311, and the specific arrangement manner thereof can be set according to practical situations, and is not limited in particular. The user may rotate the second housing 312 through the first through-hole.

Referring to fig. 2, 5 and 11, in this embodiment, mounting ring 313 is substantially circular, and mounting ring 313 may be made of plastic or metal or other lightweight material. The second housing 312 is fixedly connected to the mounting ring 313 and then fixedly mounted to the panel 10 via the mounting ring 313. Specifically, the mounting ring 313 is formed at the bottom thereof with a second mounting portion 3131, and the second mounting portion 3131 is mated with the first mounting portion 11 on the panel 10 to mount the mounting ring 313 on the panel 10, thereby mounting the knob assembly 31 on the panel 10. In the illustrated example, the first mounting portion 11 includes a mounting hole 13 formed on the panel 10, the second mounting portion 3131 includes a mounting post 3132, each of the mounting hole 13 and the mounting post 3132 is plural, and the mounting posts 3132 respectively cooperate with the mounting holes 13 to stably mount the mounting ring 313 on the panel 10. The mounting hole 13 may be a blind hole or a through hole.

In the illustrated example, the number of the mounting holes 13 is 4, and the mounting posts 3132 are arranged in an isosceles trapezoid shape on the panel 10 along the circumferential direction of the first window 101, and the number of the mounting holes 13 corresponds to the number of the mounting posts. Thus, the fitting of the mounting hole 13 and the mounting post 3132 enables the mounting ring 313 to be stably mounted on the panel 10. In addition, the arrangement of the mounting holes 13 of the present embodiment is fool-proof, so that the mounting ring 313 can be accurately mounted on the panel 10 when the knob assembly 31 is mounted, thereby preventing mounting errors from affecting the assembly efficiency.

It is understood that in other embodiments, the number of mounting holes 13 and mounting posts 3132 may be less than 4 or more than 4, such as 3 or 5 or even more. Further, the mounting post 3132 may also be a mounting post 3132 with a screw hole, and a screw may be combined with the mounting post 3132, so that the knob assembly 31 is more firmly mounted on the panel.

Referring to fig. 8, in the present embodiment, the adhesive 315 is disposed at the bottom (right side in the figure) of the mounting ring 313, in the embodiment shown in the figure, the adhesive 315 is inserted into the first mounting portion 11 at the bottom of the mounting ring 313, and the adhesive 315 connects the mounting ring 313 and the panel 10 to fixedly connect the two. In this way, the first and second mounting

portions

11 and 3131 can accurately position and mount the mounting ring 313 on the panel 10, and the adhesive 315 can fixedly connect the two. Therefore, the rapid and accurate positioning installation and the rapid fixation can be realized.

In this embodiment, the adhesive member 315 may be a double-sided tape or other connecting element including an adhesive base material having adhesion. Generally, before fixing the knob assembly 31, the surface of the adhesive member 315 is covered with a protective film 3151, and in use, referring to fig. 8, the protective film 3151 is peeled off to expose the adhesive member 315, and then the knob assembly 31 is adhered to the panel 10 through the adhesive member 315.

It will be appreciated that in some embodiments, the knob assembly 31 may also be provided without the adhesive 315, but directly mate with the first and second mounting

portions

11, 3131 to directly fixedly mount the mounting ring 313 to the panel 10. For example, the first mounting portion 11 and the second mounting portion 3131 may be detachably connected by a snap connection, so that the mounting ring 313 is fixedly snapped on the panel 10 by the snap connection, and thus the knob assembly 31 and the panel 10 are detachably connected, and when the knob assembly 31 needs to be repaired or replaced, the knob assembly 31 can be more conveniently and quickly detached from the panel 10.

In other embodiments, the first and second mounting

portions

11 and 3131 may not be formed on the mounting ring 313 and the panel 10, but the mounting ring 313 and the panel 10 may be directly fixed and connected by an adhesive.

As shown in fig. 2, in the present embodiment, the mounting ring 313 and the second housing 312 are formed as separate bodies, that is, they are formed as separate bodies and then mounted together. It is understood that in other embodiments, the mounting ring 313 and the second housing 312 may be integrally formed to reduce the manufacturing cost of the mold and the mounting process.

Referring to fig. 2, 4 and 6, in the present embodiment, the sensor assembly 40 includes a sensor 41, a sensor circuit board 42 and a bracket 43.

The bracket 43 is mounted on the lower surface of the panel 10, the sensor 41 is disposed on the sensor circuit board 42 and electrically connected to the sensor circuit board 42, the sensor circuit board 42 is mounted on the bracket 43, the bracket 42 is frame-shaped, and the sensor 41 is exposed from the hollow portion of the bracket 43 to reduce the obstruction of the sensor 41 to the sensing ring 314. The holder 43 is used to support and place the sensor circuit board 42 and the sensor 41 to prevent the sensor 41 and the sensor circuit board 42 from falling, the sensor circuit board 42 is disposed on the lower surface of the holder 43, and the sensor circuit board 42 and the display screen circuit board 22 may be connected by a flexible circuit board 50. The bracket 43 may be fixedly mounted on the lower surface of the panel 10 by other adhesives such as glue or other elements capable of bonding the bracket 43 and the panel 10, and may also be fixed by means of a snap or a screw.

Specifically, the flexible circuit board 50 includes a first connector 51, a second connector 52, and a cable 53 connecting the first connector 51 and the second connector 52, and the flexible circuit board 50 is connected to the display circuit board 22 through the first connector 51 and to the sensor circuit board 42 through the second connector 52.

The sensor 41 is used for sensing the position of the induction ring 314 to control the display content of at least the first display region 211 of the display screen 21. In the present embodiment, the mounting ring 313 is located at the bottom of the knob assembly 31, the notch 3133 is formed on the mounting ring 313, and referring to fig. 2 and 4, the sensing ring 314 includes a portion corresponding to the notch 3133, that is, the sensing ring 314 can be partially exposed out of the notch 3133 for the sensor 41 to sense, so that the sensing interference between the sensing ring 314 and the sensor 41 can be reduced, and the sensing accuracy is improved.

Referring to fig. 12, in order to enable the sensor 41 to more accurately sense the position of the sensor ring 314, a second through hole 12 is formed in the panel 10 at a position corresponding to the sensor 41, and the position of the second through hole 12 corresponds to the position of the notch 3133. That is, the second through-hole 12 is located substantially directly below the notch 3133, and the sensor 41 is located substantially directly below the second through-hole 12. In this way, the sensor 41 can accurately sense the position of the sensing ring 314 through the second through hole 12 and the notch 3133 to control at least the display content of the first display region 211 (the arrow in fig. 12 and the arrow at the second through hole 12 in fig. 4 both represent the sensing path of the sensor 41).

In the present embodiment, the induction ring 314 includes a magnetic ring, the sensor 41 includes a hall sensor, and the magnetic ring has a gear ring shape, that is, a plurality of teeth are formed on the periphery of the magnetic ring, and a gap exists between two adjacent teeth. Each tooth may represent a magnetic pole. The magnetic poles of two adjacent teeth are identical or opposite in polarity. In one example, the Hall sensor may be a Texas Instruments Incorporated Hall sensor model "DRV 5033 FAQDBZR".

Specifically, referring to fig. 14 to 16, when the user rotates the first housing 311 to rotate the sensor ring 314, the teeth of the sensor ring 314 or the gap between two teeth is detected by the sensor 41 through the notch 3133 and the second through hole 12. The specific detection process of the sensor 41 is as follows: first, in the example shown in fig. 14 and 15 (fig. 14 is a top view angle, and fig. 15 is a bottom view angle), when one tooth of the sense ring 314 is positioned directly above the sensor 41, the sensor 41 detects a peak value of the magnetic field signal. In the example shown in fig. 16, the teeth of the inductive loop 314 are not directly above the sensor 41 but are located on both sides of the sensor 41, that is, the sensor 41 is located directly below the gap between two teeth, and in this case, the sensor 41 does not detect a signal or detects a peak value other than a magnetic field signal, thereby causing a change in the output signal of the sensor 41. In this way, the sensor 41 can record how many teeth the sensor ring 314 has rotated, so that the position of the sensor ring 314 can be determined according to the recorded information, thereby controlling the display content of the display screen 21. (in the example shown in FIGS. 14 to 16, the sensor 41 is indicated by a dashed line frame)

It is understood that, in the present embodiment, the panel 10 is made of glass or plastic and is not made of a magnetic shielding material, and therefore, the panel 10 may not be provided with the second through hole 12, and the sensor 41 may sense the position of the sensing ring 314 through the panel 10 (as shown in fig. 13, the arrow in fig. 13 indicates the sensing path of the sensor 41). In other embodiments, mounting ring 313 may be made of a non-magnetic shielding material, so that mounting ring 313 may not be notched 3133 and sensor 41 senses the position of sensor ring 314 through mounting ring 313.

In addition, the position of the induction ring 314 is sensed by the cooperation of the magnetic ring and the hall sensor in the present embodiment. In other embodiments, sensing may be performed in other manners, for example, by detecting the proximity, capacitance or resistance between the sensor 41 and the sensor 314, and the sensor 41 may also include an optoelectronic switch, and sensing the position of the sensor 314 by sensing light or the like. The specific implementation manner can be determined according to actual conditions.

In the present embodiment, the user can control the first display content of the display screen 21 through the knob assembly 31. For example, when the working temperature needs to be set, the temperature parameter can be set through the knob assembly 31, and the temperature can be increased or decreased; when the working time needs to be set, the working time can be set through the knob component 31, and the working time is increased or decreased; when the working power needs to be set, the working power can be set through the knob assembly 31, and the working power is increased or decreased.

The following description will be given taking the set operating temperature as an example. First, it should be noted that, in the illustrated example, the number of each tooth of the induction ring 314 is only used for marking a position so as to more clearly describe a specific working process thereof, and there is no limitation on whether there is a number on the entity of the induction ring 314, that is, there may be a number or no number on the entity of the induction ring 314.

Referring to fig. 17, in fig. 17, when the first display area 211 shows 179 °, the tooth 7 of the sensing ring 314 is located right above the notch 3133 and the sensor 41, and the sensor 41 records a signal, when the user needs to adjust the operating temperature again, the user can rotate the first housing 311 of the knob assembly 31, the first housing 311 rotates the sensing ring 314, and when the user rotates one tooth clockwise (rotates the tooth 6 to above the notch 3133 and the sensor 41), the setting of the first display area 211 is increased by 1. Specifically, during the rotation, the sensor 41 is always in the sensing state, when the gap between the two teeth is located right above the sensor 41, the signal of the sensor 41 is absent, and then when the sensor 41 rotates to the tooth 6, the sensor 41 can sense the signal again, so that the sensor 41 records that the sensing ring 314 rotates clockwise by one tooth, thereby transmitting the data to the sensor circuit board 42, and after the data is processed by the sensor circuit board 42 or other control devices (such as a processor arranged on the sensor circuit board 42), the value displayed by the display screen 21 is controlled by adding 1 through the flexible circuit board 50 and the display screen circuit board 22, that is, the first display area 211 of the display screen 21 displays 180 ° (as shown in fig. 18). On the basis of fig. 18, when the sensor ring 314 rotates one tooth further clockwise (to rotate the tooth 5 over the notch 3133 and the sensor 41), the displayed value of the first display area 211 is again 1 (i.e., 181 °, as shown in fig. 19).

In the present embodiment, the set temperature displayed in the first display region 211 is increased by 1 for every clockwise rotation of the inductor ring 314 by one tooth, and the set temperature is decreased by 1 for every counterclockwise rotation by one tooth. It is understood that in other embodiments, the set temperature may be plus 1 for every counterclockwise rotation of one tooth or two or more teeth, and minus 1 for every clockwise rotation of one tooth or two or more teeth, without limitation.

It should be noted that, in the present embodiment, in order to enable the sensor 41 to identify whether the sense loop 314 rotates clockwise or counterclockwise, clockwise and counterclockwise detection can be implemented by setting a mark point on the sense loop 314, that is, the sensor 41 can detect position information of the mark point to determine whether the sense loop 314 rotates clockwise or counterclockwise, for example, each tooth of the sense loop 314 is specially numbered, and the identification number is used to determine whether the sense loop 314 rotates counterclockwise or clockwise.

In addition, referring to fig. 17a and 17b, in some embodiments, in order to enable the sensor 41 to identify whether the sensor ring 314 rotates clockwise or counterclockwise, the sensor ring 314 may be formed by connecting a plurality of magnetic poles, and the polarities of two adjacent magnetic poles are opposite, so that a sensor 44 having the same or similar function as the sensor 41 may be additionally disposed at a position adjacent to the sensor 41 on the sensor circuit board 42, so that the rotation direction may be determined by detecting the signal difference between the two sensors.

Specifically, as shown in fig. 17b, the sensor 41 is disposed just below the N-pole or S-pole (i.e., the sensor 41 is covered by a single magnetic pole), and the sensor 44 is disposed at an intermediate position between the N-pole and S-pole (i.e., a part of the sensor 44 is covered by one N-pole and another part is covered by an adjacent S-pole) with a gap of 1.5 magnetic poles from the sensor 41.

First, for convenience of understanding, a description will be given taking as an example that a signal detected by the sensor 44 is "1" when the sensor 44 is located directly below the N pole (i.e., the sensor 44 is covered by the N pole), and a signal detected by the sensor 44 is "0" when the sensor 44 is located directly below the S pole (i.e., the sensor 44 is covered by the S pole), and further, a signal detected by the sensor 44 is "0" when a part of the sensor 44 is covered by the N pole and another part of the sensor is covered by the adjacent S pole. As shown in fig. 17b, when the sensor ring 314 rotates clockwise, the sensor 44 is located directly under the S pole first and then located at the middle position between the N pole and the S pole, in the process, the detection signal of the sensor 44 is always 0, and when the sensor ring 314 rotates counterclockwise, the sensor 44 is located under the N pole first and then located at the middle position between the N pole and the S pole, in the process, the detection signal of the sensor 44 changes from 0 to 1 and then to 0 again. Thus, it is determined whether the inductor loop 314 rotates clockwise or counterclockwise according to the change of the detection signal of the sensor 44.

In the illustrated embodiment, the number of teeth of the inductor ring 314 is 22, and 22 teeth are evenly distributed on the inductor ring 314. It is understood that in other embodiments, the number of teeth of the inductive loop 314 may be less than 22 or greater than 22, and is not limited.

In addition, in the present embodiment, the inductor 314 is provided in a gear ring shape, a gap exists between two teeth, and the sensor 41 determines the position of the inductor 314 by sensing the number of signal peaks and the number of signal losses or reductions. It is understood that in other embodiments, the inductive ring 314 may be configured in a ring shape, and the inductive ring 314 has a plurality of magnetic poles, and the two adjacent magnetic poles have opposite polarities. The sensor 41 may form different detection information with the N-pole and the S-pole, for example, when the N-pole is used, the number is recorded as 1, and when the S-pole is used, the number is recorded as 0, so that when the induction ring 314 rotates, the sensor 41 may record the number of N-pole information or S-pole information to detect how many N-poles or S-poles the induction ring 314 rotates, thereby detecting the position of the induction ring 314. The specific setting mode can be set according to the actual situation.

Referring to fig. 2, fig. 5 and fig. 7, in the present embodiment, the positioning device 60 is mounted on the first housing 311, and the positioning device 60 is used for positioning the relative rotation position of the first housing 311 and the second housing 312. The positioning device 60 includes a support 61 and a holding assembly 62.

The supporting member 61 is mounted on the first housing 311, the holding member 62 is mounted on the supporting member 61, and the holding member 62 telescopically holds the second housing 312.

The abutting assembly 62 includes an elastic member 621 and an abutting member 622, the elastic member 621 is mounted on the supporting member 61, the abutting member 622 is connected to the elastic member 621, and the elastic member 621 is used for generating an elastic force acting on the abutting member 622 so that the abutting member 622 abuts against the second housing 312.

With reference to fig. 20 and 21, in order to cooperate with the positioning device 60 to position the first housing 311 and the second housing 312, a plurality of positioning members 3122 are formed on an outer wall 3113 of the second housing 312 and are arranged along a circumferential direction of the second housing 312, and the supporting member 622 can be positioned and connected to one of the positioning members 3122. In this embodiment, the positioning member 3122 includes a groove 3123, and the abutting member 622 can abut against one groove 3123.

Specifically, referring to fig. 7, 20 and 21, the elastic element 621 can be fixedly mounted on the supporting element 61, the abutting element 622 is inserted on the elastic element 621, the abutting element 622 abuts against a groove 3123 on the second housing 312, when the user rotates the first housing 311, the elastic element 621 and the abutting element 622 rotate along with the first housing 311, and the second housing 312 is stationary. At this time, the holding member 622 slides out of the groove 3123 under the force and then slides into the adjacent groove 3123. When the holding member 622 slides out of the groove 3123, the elastic member 621 is compressed by the holding member 622. Then, when sliding into the adjacent groove 3123, the pushing force generated by the elastic element 621 makes the abutting element 622 rapidly insert into the groove 3123 and abut against the groove 3123.

It can be understood that, in the present embodiment, the number of the grooves 3123 corresponds to the number of the teeth of the sensing ring 314, and the positions of the grooves 3123 correspond to the positions of the teeth of the sensing ring 314 (see fig. 20), that is, each time the sensing ring 314 rotates by one tooth, the holding member 622 slides into the adjacent groove 3123 from the groove 3123 where the holding member 622 is located, and the holding member 622 impacts the groove 3123 under the elastic force of the elastic member 621 during the sliding process to generate an impact sound for feedback. Therefore, the user can intuitively perceive how much the induction ring 314 rotates, and the user does not need to spend more time to judge whether the first shell 311 is located at the position expected by the user, so that the user experience is improved.

Referring to fig. 7, in the present embodiment, the elastic member 621 may be an elastic element such as a spring, and the abutting member 622 may be an element such as a pin, which is not limited herein as long as the positioning function can be achieved.

Further, it is understood that in some embodiments, the positioning member 3122 may also be a protrusion disposed on an outer wall of the second housing 312. Specifically, a corresponding groove may be formed at the end of the abutting member 622 to achieve the positioning of the two.

In other embodiments, the positioning device 60 may be mounted on the second housing 312 instead of the first housing 311, the supporting member 61 may be mounted on the second housing 312, the abutting member 62 may telescopically abut against the first housing 311, and the positioning member 3122 may be formed on the inner wall 3112 of the first housing 311 instead of the outer wall of the second housing 312. In this way, the positions of the first housing 311 and the second housing 312 can also be located, so that automatic accurate location is realized, and the user experience is improved.

Further, referring to fig. 2, fig. 4 and fig. 5, in the present embodiment, the decoration cover 316 is also substantially in a shape of a circular column, and the decoration cover 316 covers the first housing 311. The decorative cover 316 can be fixedly connected with the first housing 311 by means of clamping.

Specifically, referring to fig. 22, a clamping groove 3117 is disposed on the top of the first housing 311, a protruding portion (not shown) is disposed on the decorative cover 316 and is matched with the clamping groove 3117, and the clamping groove 3117 and the protruding portion are matched and connected to fix the decorative cover 316 on the first housing 311. In this way, the decorative cover 316 can improve the aesthetic feeling of the interactive assembly 100, and when the user needs to rotate the first housing 311 and the sensor ring 314, the user only needs to rotate the decorative cover 316 to drive the first housing 311 to rotate.

The operation of the interactive assembly 100 of the present embodiment will be described below, taking as an example that the first display area 211 displays the set temperature and the second display area 212 displays the operation mode.

First, in the present embodiment, the user may perform a touch operation at the second window 102 to select an operation mode of the home appliance 1000, and after the user selects, the first display region 211 at the first window 101 displays the set operation temperature. Then, when the user needs to adjust the set operating temperature, the user can rotate the decoration cover 316 to drive the induction ring 314 fixedly installed in the first housing 311 to rotate, the sensor 41 senses how many teeth the induction ring 314 rotates through the notch 3133 and the second through hole 12, and then the sensor circuit board 42 and the flexible circuit board 50 transmit the sensed data to the display screen circuit board 22, thereby controlling the temperature value displayed in the first display area 211 to change.

In the rotating process, since the number of the grooves 3123 on the second housing 312 corresponds to the number of the teeth of the sensor ring 314, when the sensor ring rotates by one tooth, the supporting member 622 strikes the grooves 3123 on the second housing 312 under the action of the elastic member 621, so that the user can directly sense how many teeth the sensor ring 314 rotates by feeding back the sound to the user.

In some embodiments, the user may set the operating temperature directly by touching the second window 102 instead of using the knob assembly 31 to set the temperature. Additionally, in other embodiments, input assembly 30 may also include a touch assembly and/or a key assembly. That is, in these embodiments, the user can set or adjust the content displayed in the first display region 211 through the touch component or the key component. Further, the input assembly 30 of the embodiment of the present invention includes a knob assembly 31, a touch assembly and a key assembly, or the input assembly 30 includes a knob assembly 31 and a touch assembly, or the input assembly 30 includes a knob assembly 31 and a key assembly, or the input assembly 30 includes a touch assembly and a key assembly, or the input assembly 30 includes a knob assembly 31 or a touch assembly or a key assembly. For each of the knob assembly 31, the touch assembly and the key assembly, there may be one first display area 211, and the content displayed in the first display area 21 is set or adjusted by the corresponding assembly.

Referring to fig. 1 and 23 to 27, the display panel assembly 20 includes a side portion and a middle portion, and the input assembly 30 is disposed corresponding to the side portion and/or the middle portion of the display panel assembly 20.

Specifically, as shown in fig. 1 and 2, in the present embodiment, the input assembly 30 is correspondingly disposed at the right side of the display screen assembly 20, and the second display area 212 is located at the left side of the first display area 211.

It is understood that in other examples, the input component 30 may be disposed at other positions of the display screen 21, for example, in the examples shown in fig. 23 and 27, the input component 30 is disposed at the middle position of the display screen component 20, and the second display area 212 is disposed at two sides of the first display area 211 (in fig. 23, the second display area 212 is disposed at the left and right sides of the first display area 211; in fig. 26, the second display area 212 is disposed at the upper and lower sides of the first display area 211). In the example shown in fig. 24, the input assembly 30 is correspondingly disposed at a left side position of the display screen assembly 20, and the second display area 212 is located at a right side of the first display area 211. In the example shown in fig. 25, the input member 30 is disposed at an upper position of the display screen assembly 20, and the second display area 212 is located at a lower side of the first display area 211. In the example shown in fig. 27, the input member 30 is disposed at a lower position of the display screen assembly 20, and the second display area 212 is located at an upper side of the first display area 211.

In addition, in other examples, the number of the knob assemblies 31 may be two, and two knob assemblies 31 are correspondingly disposed on the middle and the side (both left and right sides) of the display screen assembly 20, respectively. Of course, it is understood that the two knob assemblies 30 may be located on the left and right sides or the upper and lower sides of the display screen assembly 20. Additionally, in some embodiments, the input assembly 30 may also be disposed on four corners of the display screen assembly 20, for example, an upper left corner, an upper right corner, a lower left corner, or a lower right corner.

In some embodiments, the knob assembly 31 may be formed without forming the first through hole 310, and instead, the middle region of the knob assembly 31 corresponding to the first display region 211 is made of a light-transmitting material, or the entire exterior parts of the knob assembly 31 are made of a light-transmitting material, that is, the first housing 311, the second housing 312, the mounting ring 313 and the decorative cover 316 are all light-transmitting, and then ink is applied to the positions other than the positions corresponding to the first display region 211.

In some embodiments, in order to improve the aesthetic appearance and the user experience of the household appliance 1000 and the interactive assembly 100, a transparent block matched with the first through hole 310 may be disposed in the first through hole 310, and the first display region 211 is displayed through the transparent block.

In some embodiments, the display screen 21 may not have a touch function, and the user may adjust the display content of the display screen and adjust various parameters of the household appliance 1000 during operation through the input assembly 30.

In summary, in the interactive assembly 100 of the above embodiment, since the orthographic projection of the input assembly 30 on the panel 10 at least partially overlaps the orthographic projection of the display screen assembly 20 on the panel 10, the occupied space of the display screen assembly 20 and the input assembly 30 can be reduced, the overall sense of the interactive assembly 100 can be improved, and an alternative interactive process can be provided between the display screen assembly 20 and the input assembly 30, so as to improve the user experience.
