Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen appliances, in particular to a cooking range with a screen knob and a cooking range with a screen. BACKGROUND

[0002] The cooking range knob is the core control component of gas stoves, liquefied gas stoves and other kitchen appliances, which integrates ignition and firepower adjustment functions. Users can realize continuous adjustment of the size of the firepower by rotating operation. In recent years, with the improvement of the intelligence and informatization level of kitchen appliances, some manufacturers have tried to integrate an electronic display screen on the cooking range knob to directly display the current firepower state, timing information or other interactive content, thereby improving the user experience.

[0003] However, since the cooking range knob must realize its basic firepower adjustment function through rotation, directly fixing the display screen on the knob will cause an inherent structural contradiction, that is, the display screen will rotate with the knob. This following state makes it difficult for users to stably observe the screen information when adjusting the firepower, resulting in poor reading experience and essentially weakening the practical value of adding a display screen.

[0004] That is, the existing cooking range knob cannot provide stable and easy-to-read visual feedback for users while ensuring the rotation adjustment function of the knob, which has become a technical pain point that needs to be optimized in the design of such products.

[0005] The above information disclosed in the background section is only included to enhance the understanding of the background of the present disclosure, and therefore can contain information that is not prior art known to those of ordinary skill in the art at the time of the present disclosure.

For those skilled in the art to which the present application belongs, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0077] The application provides a stove knob with a screen and a stove with a screen, which can solve the problem that the display screen on the existing stove knob rotates with the knob, causing inconvenience for users to observe.

[0078] Referring to Figures 1-11 The stove with a screen provided by the embodiment comprises:

[0079] The air inlet piece 100 is provided with an air valve mounting cavity 100a and an air inlet channel 100b;

[0080] The flow regulating valve (not shown in the drawings) comprises a regulating valve body fixedly installed in the air valve mounting cavity 100a and communicating with the air inlet channel 100b, and an air volume regulating knob arranged in rotation with the regulating valve body to regulate the air volume; specifically, the specific structure of the flow regulating valve belongs to the prior art and is not the focus of the embodiment, and thus is not described herein.

[0081] The stove knob with a screen 200 is installed above the air valve mounting cavity 100a, and the lower end of the rotating shaft sleeve assembly 3 is synchronously connected in rotation with the air volume regulating knob.

[0082] Further, the stove knob with a screen 200 comprises:

[0083] The knob bottom box 1 is provided with a central shaft hole 101 and a core shaft rotation limiting groove 102 located beside the central shaft hole 101;

[0084] The fixed core shaft assembly 2 is located at the central shaft hole 101 and is provided with a core shaft rotation limiting part 2011 that protrudes transversely to be inserted into the core shaft rotation limiting groove 102, so as to limit the relative rotation between the fixed core shaft assembly 2 and the knob bottom box 1;

[0085] The rotating shaft sleeve assembly 3 is rotatably sleeved outside the fixed core shaft assembly 2 and is provided with an avoiding gap 3011 through which the shaft rotation limiting part passes;

[0086] The knob outer shell 4 has its lower end sleeved outside the rotating shaft sleeve assembly 3 and synchronously connected in rotation with the rotating shaft sleeve assembly 3, and has its upper end provided with a screen accommodating groove 401 and a through shaft hole 402 through which the fixed core shaft assembly 2 extends into the screen accommodating groove 401;

[0087] The display screen module 5 is located in the screen accommodating groove 401 and is fixedly installed at the top end of the fixed core shaft assembly 2 that extends into the screen accommodating groove 401 through the through shaft hole 402.

[0088] Further, the height dimension of the shaft limiting groove 102 is greater than the height dimension of the shaft limiting portion 2011, so that the shaft limiting portion 2011 can slide up and down in the shaft limiting groove 102, which provides a space for the entire fixed shaft assembly 2 and the display screen module 5 mounted thereon to move up and down to cooperate with the pressing operation.

[0089] When the user rotates the knob shell 4, the knob shell 4 drives the rotating shaft sleeve assembly 3 to rotate. The fixed shaft assembly 2 is inserted into the shaft limiting groove 102 of the knob bottom box 1 through the shaft limiting portion 2011, and thus remains stationary. Since the display screen module 5 is fixedly mounted at the top end of the fixed shaft assembly 2, the display screen module 5 does not rotate when the knob rotates, and always provides a stable display screen for the user. Further, the rotation of the rotating shaft sleeve assembly 3 drives the air volume adjusting knob of the flow regulating valve to rotate, thereby changing the air volume and realizing fire control.

[0090] The stove knob with a screen 200 and the stove with a screen provided by the present application decouple the display screen module 5 for displaying information and the rotating shaft sleeve assembly 3 for performing rotating adjustment function in mechanical movement through a precise coaxial nesting structure design.

[0091] Specifically, the fixed shaft assembly 2 serves as a static reference of the entire knob, and is strictly limited to rotate through the cooperation of the shaft limiting portion 2011 and the shaft limiting groove 102 on the knob bottom box 1. The display screen module 5 is fixedly mounted at the top end of the fixed shaft assembly 2, thereby ensuring that it remains stationary during the operation of the knob and providing a stable and easy-to-read visual interface for the user.

[0092] At the same time, the rotating shaft sleeve assembly 3 is rotatably sleeved outside the fixed shaft assembly 2 and is driven to rotate by the user through the knob shell 4, so as to independently perform control functions such as fire adjustment or ignition signal triggering. This “separation of motion and static” architecture fundamentally solves the problem of inconvenient observation caused by the screen following the rotation of the traditional knob with a screen.

[0093] Therefore, the stove knob with a screen 200 and the stove with a screen provided by the present application can solve the problem that the display screen of the existing stove knob rotates with the knob, causing inconvenience for the user to observe.

[0094] In the embodiment, the rotating shaft sleeve assembly 3 includes:

[0095] The shaft sleeve main piece 301 is movably mounted in the center shaft hole 101, and is provided with the avoidance notch 3011 and the shaft insertion slot 3012 for inserting the fixed shaft assembly 2 from top to bottom to support the fixed shaft assembly 2 upwardly;

[0096] An axial limiting ring 302 is arranged in the knob bottom box 1 and fixedly arranged at the lower end of the shaft sleeve main part 301, and the outer diameter of the axial limiting ring 302 is larger than the diameter of the central shaft hole 101, so as to limit the axial limiting ring 302 from passing through the central shaft hole 101 upwardly;

[0097] A reset compression spring 303 is arranged below the axial limiting ring 302, and used for upwardly pushing the axial limiting ring 302;

[0098] A gas valve connecting shaft 304 is fixedly arranged at the bottom of the shaft sleeve main part 301 and synchronously rotates with the shaft sleeve main part 301, and the lower end of the gas valve connecting shaft 304 protrudes downwardly below the knob bottom box 1 and is connected with the gas volume adjusting knob, so as to drive the gas volume adjusting knob to rotate.

[0099] Further, the cooking knob with screen 200 further comprises:

[0100] An ignition pressing piece 6 comprises an annular pressing piece main body 601 arranged between the shaft sleeve main part 301 and the axial limiting ring 302 and synchronously moving upwardly and downwardly with the rotating shaft sleeve assembly 3, and an ignition extending part 602 and a pressing piece limiting rotation part 603 protruding outwardly from the pressing piece main body;

[0101] An ignition micro switch 7 is fixedly arranged in the knob bottom box 1 and below the ignition extending part 602, and used for sending an ignition signal after being pressed by the ignition extending part 602;

[0102] The knob bottom box 1 is provided with a pressing piece limiting rotation groove 103 for transversely inserting the pressing piece limiting rotation part 603, so as to limit the relative rotation between the ignition pressing piece 6 and the knob bottom box 1.

[0103] The pressing piece limiting rotation part 603 is arranged to slide upwardly and downwardly in the pressing piece limiting rotation groove 103.

[0104] The shaft sleeve main part 301 of the rotating shaft sleeve assembly 3 realizes the axial positioning and reset functions through the axial limiting ring 302 (the outer diameter of which is larger than the diameter of the central shaft hole 101) and the reset compression spring 303:

[0105] (1) When the user presses the knob shell 4 downward, the force is transmitted to the shaft sleeve main part 301 through the knob shell 4, overcomes the elastic force of the reset compression spring 303, and drives the entire rotating shaft sleeve assembly 3 to move downward. Since the ignition pressing piece 6 moves up and down synchronously with the rotating shaft sleeve assembly 3, when the ignition extension part 602 thereof moves downward, it will press the ignition microswitch 7 fixed in the knob bottom box 1, triggering the ignition signal. During this period, the pressing piece limiting part 603 of the ignition pressing piece 6 is inserted into the pressing piece limiting groove 103 of the knob bottom box 1, preventing the ignition pressing piece 6 from rotating by itself, and ensuring the accuracy of the pressing action;

[0106] (2) After the user releases the knob shell 4, the rotating shaft sleeve assembly 3 is reset upward under the action of the reset compression spring 303, synchronously driving the ignition pressing piece 6 to release the ignition microswitch 7 upward.

[0107] In the embodiment, the fixed mandrel assembly 2 comprises:

[0108] The mandrel bottom support 201 is located in the shaft sleeve main part 301, the lower end of the mandrel bottom support 201 is provided with the mandrel limiting part 2011, and the top of the mandrel bottom support 201 is provided with the bottom support same rotation groove 2012 opening upward;

[0109] The lower end sub support 202 is inserted into the mandrel bottom support 201, the upper part of the lower end sub support 202 is located above the mandrel bottom support 201 and is provided with the lower sub support same rotation groove 2021 aligned with the bottom support same rotation groove 2012 upward and downward;

[0110] The lower connector 203 is fixedly installed on the top of the lower end sub support 202;

[0111] The upper end sub support 204 is located above the lower end sub support 202, and is provided with the upper sub support limiting plug-in plate 2041 inserted into the bottom support same rotation groove 2012 after penetrating the lower sub support same rotation groove 2021 downward, so as to limit the relative rotation among the mandrel bottom support 201, the lower end sub support 202 and the upper end sub support 204;

[0112] The upper connector 205 is fixedly installed on the bottom of the upper end sub support 204 and is connected with the lower connector 203;

[0113] The top surface center position of the upper end sub support 204 is protruded upward through the penetrating shaft hole 402, and the display screen module 5 is fixed on the top of the upper end sub support 204 and is electrically connected with the upper connector 205;

[0114] The hole edge of the through shaft hole 402 abuts against the top surface edge position of the upper terminal support 204, so that the knob shell 4 is driven to move downward, and the upper terminal support 204 is synchronously driven to move downward.

[0115] Further, both of the terminal supports are provided with longitudinal wire cavities 2022 for corresponding connector wires;

[0116] The inside of the shaft limiting part 2011 is provided with a transverse wire cavity 2011a which is communicated to the longitudinal wire cavity 2022 of the lower terminal support 202.

[0117] The space below the fixed shaft assembly 2 is extremely compact, and if the lower connector 203 is wired from directly below the fixed shaft assembly 2, it is easy to cause interference and winding problems, greatly increasing the design difficulty. The design of the transverse wire cavity 2011a can make the wire exit from the side of the center axis, reducing the design difficulty. Therefore, the shaft limiting part 2011 not only can limit rotation, but also can provide a wire channel, and the function is highly integrated.

[0118] In the embodiment, the shaft limiting part 2011 is radially aligned with the bottom support same rotation groove 2012, and the top of the transverse wire cavity 2011a is an open structure;

[0119] The lower terminal support 202 is provided with a wire cavity cover plate 2023 which protrudes through the bottom support same rotation groove 2012 to the upper side of the shaft limiting part 2011 and covers the top opening of the transverse wire cavity 2011a.

[0120] The stove with a screen knob 200 is small in size, and the size of the shaft limiting part 2011 is limited, so the internal space of the transverse wire cavity 2011a is also limited. Directly inserting the wire from one end may cause the wire to be stuck inside. Therefore, the top opening structure is provided, which can guide the wire bundle with a needle or other tools when the wire bundle is stuck, and the wire bundle is stretched out from the other end of the transverse wire cavity 2011a. After that, the lower terminal support 202 is completely installed into the shaft bottom support 201.

[0121] Further, the outer diameter size of the shaft sleeve main part 301 is greater than the outer diameter size of the upper terminal support 204, so that the shaft sleeve main part 301 protrudes outwardly relative to the upper terminal support 204 in the radial direction, and the part of the shaft sleeve main part 301 which protrudes outwardly relative to the upper terminal support 204 in the radial direction is provided with a shaft sleeve same rotation groove 3013.

[0122] The knob shell 4 is provided with a shell same rotation boss 403 which is inserted into the shaft sleeve same rotation groove 3013 from top to bottom, so as to limit the relative rotation between the knob shell 4 and the shaft sleeve main part 301.

[0123] The fixed mandrel assembly 2 adopts a modular stacking design: the mandrel base 201 serves as a base, and the mandrel rotation limiting part 2011 realizes circumferential limiting with the bottom box; the lower end support 202 and the upper end support 204 are locked with each other by inserting the upper support rotation limiting plug-in plate 2041 into the same rotation groove 2012 of the base and the same rotation groove 2021 of the lower support, and are fixed with the mandrel base 201, forming a rigid overall static support structure.

[0124] The upper connector 205 and the lower connector 203 are internally connected in the support, and supply power and transmit signals for the display screen module 5 at the top. In view of the wiring problem in the compact space, a horizontal wiring cavity 2011a is arranged in the mandrel rotation limiting part 2011, so that the cable can be led out from the side of the fixed mandrel assembly 2 instead of directly below, effectively avoiding interference and winding with the moving parts such as the lower rotary shaft sleeve assembly 3. The synchronous rotating connection between the knob shell 4 and the rotary shaft sleeve assembly 3 is realized by the plug-in cooperation between the shaft sleeve same rotation groove 3013 on the shaft sleeve main part 301 and the shell same rotation boss 403 on the knob shell 4. Thus, in the extremely compact space, not only the stable static support and reliable electrical connection of the display screen module 5 are realized, but also the technical bottleneck of internal cable layout is ingeniously solved, and the efficient transmission of power from the knob shell 4 to the rotary shaft sleeve assembly 3 is ensured through the simple slot structure, and the overall structure is compact, has strong assembly property and high reliability.

[0125] Optionally, the screen accommodating groove 401 is a top opening structure, and the opening position is provided with a transparent cover plate 404, so that the user can observe the content displayed on the display screen module 5 through the transparent cover plate 404.

[0126] The detailed working process of the stove with a screen knob 200 and the stove with a screen provided by the embodiment can be clearly divided into three main stages: standby and information display stage, pressing ignition stage and rotating to adjust fire stage.

[0127] First stage: standby and information display - establishment of static information platform

[0128] When the device is powered on and not in operation, the device is in standby state. At this time, its core task is to ensure that the display module 5 stably displays information. This function is achieved through the precise design of the fixed mandrel assembly 2. The mandrel limiting rotation part 2011 at the lower end of the mandrel base 201 of the fixed mandrel assembly 2 is transversely inserted into the mandrel limiting rotation groove 102 of the knob base box 1. This cooperation fundamentally limits the rotation of the fixed mandrel assembly 2 relative to the stove body. The mandrel base 201, the lower end sub support 202 and the upper end sub support 204 are interlocked by the upper support limiting rotation plug-in plate 2041 and the plug-in of the bottom support same rotation groove 2012 and the lower support same rotation groove 2021, forming a rigid whole. The display module 5 is fixed to the top of this rigid whole, the top of the upper end sub support 204. Therefore, no matter how the outside operates, the display module 5 is always anchored on the knob base box 1 by the fixed mandrel assembly 2, keeping absolute stillness, providing a clear and non-shaking interface for the user, such as time, firepower level or recipe information. Power supply and signal transmission are connected through the docking of the upper connector 205 and the lower connector 203 fixed on the upper end sub support 204 and the lower end sub support 202. The cable enters the lateral wire channel 2011a of the mandrel base 201 through the vertical wire channel 2022 of the lower end sub support 202, and is finally led out from the lateral of the mandrel limiting rotation part 2011. This wire path perfectly avoids the lower moving parts, ensuring the reliability of electrical connection.

[0129] Second stage: press the ignition - axial movement and signal triggering

[0130] 1. Force transmission and assembly downward movement: the user presses the knob shell 4 downward along the axial direction.

[0131] The pressure is transmitted through two paths:

[0132] Path one (to the rotating shaft sleeve assembly 3): the inner wall of the knob shell 4 presses the radially protruding part of the shaft sleeve main part 301 downward, driving the entire rotating shaft sleeve assembly 3 to compress the return spring 303 and move downward.

[0133] Path two (to the fixed mandrel assembly 2): the hole edge of the upper end shaft hole 402 of the knob shell 4 presses the top surface edge of the upper end sub support 204 downward. Because the height of the mandrel limiting rotation groove 102 is greater than the height of the mandrel limiting rotation part 2011, there is a movable gap, so the entire fixed mandrel assembly 2 (including the mandrel base 201, the lower end sub support 202, the upper end sub support 204 and the display module 5 above) also produces a small displacement downward.

[0134] 2. Triggering the ignition signal:

[0135] (1) With the downward movement of the rotating shaft sleeve assembly 3, the ignition tablet 6 fixed thereon (between the shaft sleeve main part 301 and the axial limiting ring 302) moves downward synchronously.

[0136] (2) Ignition extension 602 of ignition tablet 6 is pressed to ignition micro switch 7 fixed on knob base box 1.

[0137] (3) Ignition micro switch 7 is triggered, sending ignition signal to stove control system, ignition device (such as pulse igniter) starts working, igniting gas.

[0138] Key design: tablet limiting part 603 of ignition tablet 6 is inserted into tablet limiting groove 103 of knob base box 1, ensuring that ignition tablet 6 itself will not rotate with knob, thereby ensuring accurate alignment of ignition micro switch 7 every time it is pressed.

[0139] Third stage: rotating to adjust fire power - rotation motion and signal generation

[0140] After successful ignition, the user rotates knob shell 4 to adjust the size of the fire power. The core of this stage of the device is the transmission and conversion of rotation motion:

[0141] 1. Power input and transmission: the user rotates knob shell 4, and its rotation force drives rotating shaft sleeve assembly 3 (including shaft sleeve main part 301 and air valve connecting shaft 304) to rotate around static fixed core shaft assembly 2 through the cooperation of shell same rotation boss 403 and shaft sleeve same rotation groove 3013. Fixed core shaft assembly 2 remains stationary because its core shaft limiting part 2011 is limited in core shaft limiting groove 102, and its top end display screen module 5 continues to provide stable display.

[0142] 2. Fire power control: the rotation of air valve connecting shaft 304 at the lower end of rotating shaft sleeve assembly 3 directly drives the synchronous rotation of the gas volume adjusting knob of the flow regulating valve in gas valve mounting cavity 100a, thereby achieving precise and continuous adjustment of the gas supply volume, and finally completing the stepless control of the fire power.

[0143] In summary, through the ingenious idea of "dynamic-static separation", the fixed core shaft assembly 2 and the rotating shaft sleeve assembly 3 are coaxially nested, the absolute fixation of the static display platform is achieved by the core shaft limiting part 2011 and the core shaft limiting groove 102, the efficient transmission of dynamic operation force is achieved by the shaft sleeve same rotation groove 3013 and the shell same rotation boss 403, and the axial pressing function and the compatibility of the floating of static components are achieved by the additional height space of the core shaft limiting groove 102. The entire working process is closely linked, and the functions of each component are highly integrated, synchronously realizing the three core functions of screen static display, ignition pressing, and rotation fire adjustment in a very compact space without interference, greatly improving the reliability, user experience, and small design level of the product.
