[0074] In the description of the present application, it should be noted that unless otherwise specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, and it can be the communication between the two elements inside. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0075] In view of the technical problem that the control function of the magnetically controlled knob of the electric appliance in the related art is less, the electric appliance provided in the embodiments of the present application includes a mounting plate and a magnetically controlled knob, the magnetically controlled knob includes a knob assembly and a control assembly which are magnetically attracted to both sides of the mounting plate, a first magnetic member and a third magnetic member are magnetically attracted to each other, so that the knob assembly and the control assembly are magnetically attracted to both sides of the mounting plate and are positioned. When the knob assembly rotates around its own axis, the detection circuit board can detect the rotation direction and rotation angle of the second magnetic member, thereby realizing one control function of the electric appliance. When the user touches the touch side of the shell, the touch signal from the touch side is transmitted to the touch circuit board through the second magnetic member and the connecting side, thereby realizing another control function of the electric appliance, and the control function of the magnetically controlled knob is increased.

[0076] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0077] The electrical equipment in this application embodiment can be a gas stove, range hood, washing machine, or other electrical equipment.

[0078] refer to Figure 1 The electrical equipment in this application embodiment may include a mounting plate 10 and a magnetic control knob 20. The magnetic control knob 20 is disposed on the mounting plate 10, and the control function of the electrical equipment is realized through the magnetic control knob 20.

[0079] Taking a gas stove as an example, the mounting plate 10 can be the panel of the gas stove, and the magnetic control knob 20 is set on the mounting plate 10 to control the gas stove, such as controlling the gas stove to ignite, adjust the fire level, or control the gas stove to turn off.

[0080] refer to Figure 2 The mounting plate 10 may have an inner side 102 and an outer side 101. The outer side 101 of the mounting plate is oriented toward the user, and the inner side 102 of the mounting plate is disposed opposite to the outer side 101 of the mounting plate.

[0081] refer to Figure 2 The magnetic control knob 20 may include a knob assembly 30 and a control assembly 40. The knob assembly 30 is disposed on the outer side 101 of the mounting plate. The control assembly 40 is disposed on the inner side 102 of the mounting plate. The knob assembly 30 and the control assembly 40 can be magnetically attached to both sides of the mounting plate 10.

[0082] refer to Figure 3 and Figure 4 The knob assembly 30 may include a housing 310. The housing 310 can transmit touch signals. The housing 310 can be made of a material capable of transmitting touch signals, such as metal or glass. The housing 310 may be generally cylindrical in shape. The two ends of the housing 310 along its axial Y direction may each have a touch side 311 and a connection side 312, which can be arranged opposite to each other. At least a portion of the connection side 312 is fitted into the mounting plate 10.

[0083] The first magnetic element 340 can be disposed within the housing 310. The first magnetic element 340 can be a magnet or other magnetic components. The magnetic field direction of the first magnetic element 340 can be along the axial direction Y of the housing 310.

[0084] It should be noted that in the description of the embodiments of this application, the direction of the magnetic field refers to the direction of the N pole of the magnetic component.

[0085] For example, referring to Figure 4 and Figure 5 , the N pole of the first magnetic member 340 can face the touch side 311, and the S pole can face the connection side 312. Alternatively, the S pole of the first magnetic member 340 can face the touch side 311, and the N pole can face the connection side 312.

[0086] For example, referring to Figure 4 and Figure 5 , the control assembly 40 can include a third magnetic member 410. The third magnetic member 410 can be disposed on the inner side 102 of the mounting plate. For example, the third magnetic member 410 can be bonded or connected to the inner side 102 of the mounting plate by other means. The third magnetic member 410 can be a magnet or other magnetic component. The magnetic field direction of the third magnetic member 410 can be along the axial direction Y of the shell 310. The third magnetic member 410 is disposed opposite to the first magnetic member 340, and the magnetic poles of the opposite ends of the third magnetic member 410 and the first magnetic member 340 are opposite, so that the third magnetic member 410 can be attracted to the first magnetic member 340, thereby enabling the shell 310 to be attracted to the outer side 101 of the mounting plate, and the shell 310 can rotate around its own axis.

[0087] For example, referring to Figure 4 and Figure 5 , in the implementation mode in which the N pole of the first magnetic member 340 faces the touch side 311 and the S pole faces the connection side 312, the N pole of the third magnetic member 410 can face the mounting plate 10, and the S pole can be away from the mounting plate 10, so that the N pole of the third magnetic member 410 is close to the S pole of the first magnetic member 340, and the third magnetic member 410 and the first magnetic member 340 can be attracted to each other.

[0088] In the implementation mode in which the S pole of the first magnetic member 340 faces the touch side 311 and the N pole faces the connection side 312, the S pole of the third magnetic member 410 can face the mounting plate 10, and the N pole can be away from the mounting plate 10, so that the S pole of the third magnetic member 410 is close to the N pole of the first magnetic member 340, and the third magnetic member 410 and the first magnetic member 340 can be attracted to each other.

[0089] In some possible implementation modes of the embodiments of the present application, referring to Figure 4 and Figure 5 , the knob assembly 30 can further include a second magnetic member 350, which can be a magnet or other magnetic component. The second magnetic member 350 can transmit a touch signal. The second magnetic member 350 can be disposed in the shell 310 and rotate with the shell 310. The magnetic field direction of the second magnetic member 350 can be along the radial direction X of the shell 310, that is, perpendicular to the axial direction Y of the shell 310.

[0090] For example, referring toFigure 4 And Figure 5 The control assembly 40 can further include a detection circuit board 430, which can be connected to the third magnetic member 410. The detection circuit board 430 is configured to detect a rotation signal of the second magnetic member 350. After detecting the rotation signal, the detection circuit board 430 converts the rotation signal into an electric signal and controls the electric appliance. For example, when the rotary knob assembly 30 is rotated, the shell 310 drives the second magnetic member 350 to rotate, and the detection circuit board 430 can detect the rotation direction and rotation angle of the second magnetic member 350, thereby achieving a control function of the electric appliance.

[0091] Taking the electric appliance as a gas stove as an example, when the rotary knob assembly 30 is rotated, the shell 310 drives the second magnetic member 350 to rotate, and the detection circuit board 430 can detect the rotation direction and rotation angle of the second magnetic member 350, thereby achieving the adjustment of the fire size of the gas stove.

[0092] In some possible implementation manners of the embodiments of the present application, referring to Figure 4 The detection circuit board 430 can include a circuit board body 431 and a chip 432. The circuit board body 431 can be connected to the third magnetic member 410. The chip 432 can be arranged on a side of the circuit board body 431 facing the mounting plate 10. The chip 432 is configured to detect the rotation signal of the second magnetic member 350.

[0093] In some possible implementation manners of the embodiments of the present application, the second magnetic member 350 is connected to the touch side 311 and the connecting side 312 at two ends along the axial direction Y of the shell 310. The second magnetic member 350 can be directly connected to the touch side 311 or indirectly connected to the touch side 311 through other components capable of transmitting a touch signal. The second magnetic member 350 can be directly connected to the connecting side 312 or indirectly connected to the connecting side 312 through other components capable of transmitting a touch signal.

[0094] Referring to Figure 4 The control assembly 40 can further include a touch circuit board 420, which can be arranged on the inner side 102 of the mounting plate 10. The touch circuit board 420 can be a flexible circuit board. The touch circuit board 420 can receive a touch signal. The touch signal from the touch side 311 is transmitted to the touch circuit board 420 through the second magnetic member 350, the connecting side 312 and the mounting plate 10.

[0095] Taking the electric appliance as a gas stove as an example, a user can touch the touch side 311. The touch signal from the touch side 311 is transmitted to the touch circuit board 420 through the second magnetic member 350, the connecting side 312 and the mounting plate 10. After receiving the touch signal, the touch circuit board 420 converts the touch signal into an electric signal and controls the gas stove. For example, the touch signal can control the ignition of the gas stove.

[0096] The electric appliance of the embodiment of the present application, when the knob assembly 30 rotates around its own axis, the detection circuit board 430 can detect the rotation signal (the rotation direction and rotation angle of the second magnetic member 350, etc.) of the second magnetic member 350, and the detection circuit board 430 realizes a control function of the electric appliance. When the user touches the touch side 311 of the shell 310, the touch signal from the touch side 311 is transmitted to the touch circuit board 420 through the second magnetic member 350 and the connecting side 312, and the touch circuit board 420 realizes another control function of the electric appliance, thereby increasing the control function of the magnetic control knob 20.

[0097] In some possible implementation manners of the embodiment of the present application, referring to Figure 4 The shell 310 can be configured to have a first accommodating space 313 and a second accommodating space 314 separated from each other. The first magnetic member 340 is arranged in the first accommodating space 313, and the second magnetic member 350 is arranged in the second accommodating space 314, so as to separate the first magnetic member 340 and the second magnetic member 350. On the one hand, the magnetic properties of the first magnetic member 340 and the second magnetic member 350 can be prevented from affecting or interfering with each other. On the other hand, the first magnetic member 340 and the second magnetic member 350 can be conveniently assembled in the shell 310.

[0098] In some possible implementation manners of the embodiment of the present application, the first accommodating space 313 can be an annular space, and the second accommodating space 314 can be a columnar space. The first accommodating space 313 can be arranged outside the second accommodating space 314, so as to improve the compactness of the relative positions of the first magnetic member 340 and the second magnetic member 350, reduce the volume of the shell 310, and thus reduce the size of the knob assembly 30.

[0099] In some possible implementation manners of the embodiment of the present application, referring to Figure 4 and Figure 5 The first magnetic member 340 can be an annular magnet. In the axial direction Y of the shell 310, the first magnetic member 340 occupies at least part of the first accommodating space 313, that is, the first magnetic member 340 can occupy part of the axial direction Y height or the entire height of the first accommodating space 313. When the first magnetic member 340 is an annular magnet, the shape of the first magnetic member 340 is matched with the shape of the first accommodating space 313, thereby facilitating the assembly of the first magnetic member 340 in the first accommodating space 313.

[0100] In some possible implementation manners of the embodiment of the present application, referring to Figure 4The axis of the second magnetic member 350 can be collinear with the axis of the shell 310, so that the shell 310 drives the second magnetic member 350 to rotate around the axis of the shell 310 when the shell 310 rotates around its own axis, so that the second magnetic member 350 is not prone to eccentric rotation relative to the axis of the shell 310, facilitating the second magnetic member 350 to maintain a relative positional relationship with the touch circuit board 420, so that the transmission path of the touch signal is substantially along the axis Y of the shell 310, improving the stability of the touch signal transmission.

[0101] In some possible implementation manners of the embodiments of the present application, referring to Figure 4 The shell 310 can include a shell body 320, and an installation cavity 321 can be formed in the shell body 320.

[0102] In some implementation manners, referring to Figure 4 The shell body 320 can include a connecting ring 323, a touch plate 324 and a bottom plate 325. The touch plate 324 and the bottom plate 325 are respectively arranged at two ends of the connecting ring 323 in the axis Y. The connecting ring 323, the touch plate 324 and the bottom plate 325 enclose the installation cavity 321.

[0103] The side of the touch plate 324 away from the bottom plate 325 has a touch side 311. The side of the bottom plate 325 away from the touch plate 324 has a connecting side 312.

[0104] The shell body 320 formed by the connecting ring 323, the touch plate 324 and the bottom plate 325 has a simple structure, facilitating processing and manufacturing.

[0105] In other implementation manners, the shell body 320 can be in a hollow columnar shape, and the installation cavity 321 is formed in the shell body 320.

[0106] In some possible implementation manners of the embodiments of the present application, referring to Figure 4 , Figure 6 , Figure 7 and Figure 8 The shell 310 can further include a mounting seat 330. At least part of the mounting seat 330 is arranged in the installation cavity 321, and the first magnetic member 340 and the second magnetic member 350 are both connected to the part of the mounting seat 330 located in the installation cavity 321.

[0107] In some possible implementation manners of the embodiments of the present application, referring to Figure 8 , Figure 9 and Figure 10 The side of the shell body 320 away from the connecting side 312 can be configured with a connecting hole 322, and part of the mounting seat 330 can be arranged in the connecting hole 322, so as to clamp the mounting seat 330 on the shell body 320, reducing the shaking of the mounting seat 330 relative to the shell body 320.

[0109] In some possible implementation manners of the embodiments of the present application, the side of the mounting seat 330 facing the mounting plate 10 can be flush with the side of the shell body 320 facing the mounting plate 10, so as to improve the flatness of the side of the shell 310 formed by the mounting seat 330 and the shell body 320 facing the mounting plate 10, and improve the reliability of the adhesion of the shell 310 to the mounting plate 10.

[0110] In the implementation where the shell body 320 includes the connecting ring 323, the touchpad 324 and the bottom plate 325, the side of the mounting seat 330 facing the mounting plate 10 can be flush with the side of the bottom plate 325 facing the mounting plate 10, so as to improve the flatness of the side of the shell 310 formed by the mounting seat 330 and the shell body 320 facing the mounting plate 10, and improve the reliability of the adhesion of the shell 310 to the mounting plate 10.
