[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] The term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present application. In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "top", "bottom", etc. is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are used only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may include one or more of the features explicitly or implicitly.

Exemplary sub-ranges of ranges 1 to 10 include, but are not limited to, 1 to 6.1, 3.5 to 7.8, 5.5 to 10, etc.

[0031] For gas stoves with electric control valves, the knobs and valves of the stoves with electric control valves do not need to be connected through the valve stem and can be sealed as a whole. Unlike gas stoves with electric control valves, the knobs of general mechanical valve gas stoves need to be connected to the valve stem and are detachable, which makes waterproofing difficult, and power supply and communication are also relatively difficult. Therefore, the knobs of mechanical valve gas stoves generally do not have interactive functions, have a low degree of intelligence, and cannot meet the requirements of the era of smart kitchen appliances. For this reason, the present application provides a knob structure and a stove.

[0032] See also Figure 1 The assembly relationship between the knob structure provided in this application and the stove is as follows: Figure 1 As shown, the cooker surface is used as the boundary to be divided into a main body 1 above the cooker surface and a mounting part 2 below the cooker surface. Among them, the components that support and protect the main body 1 include a shell 17, a supporting structure 15 tightly embedded in the shell 17, and a bottom plate 13 of the main body 1. The printed circuit board assembly 11 is connected and fixed to the supporting structure 15, and the mounting part 2 is arranged on the gas valve body 4. The display screen 12 is bonded to a transparent or translucent display screen cover plate 16. In some embodiments, the bonding material can be OCA glue. For example, the cover plate material is a transparent substrate with a certain strength. The cover plate material can be glass, acrylic, etc. The valve stem 3 passes through the potentiometer 21 and is fixedly connected to the accommodating structure 131 of the main body 1.

[0033] The printed circuit board assembly 11 is connected to the display screen 12 via a connecting line 18, the printed circuit board assembly 11 is connected to the second socket 221 on the signal receiving device 22 via the first socket 111, and the pins of the potentiometer 21 are connected to devices such as a power supply.

[0034] Furthermore, the printed circuit board assembly 11 may be waterproofed, for example, by coating with a three-proof glue, paint, or pouring with glue.

[0035] Please continue to see Figure 1 On the one hand, the present application provides a knob structure for use in a cooker, characterized in that the knob structure includes a main body 1 and a mounting portion, the main body 1 and the mounting portion are fixedly connected to the surface of the cooker, the main body 1 includes a printed circuit board assembly 11 and a display screen 12 for displaying information, the printed circuit board assembly 11 is electrically connected to the display screen 12 and the mounting portion respectively; a position indicator indicating the position of the main body 1 is provided on the mounting portion.

[0036] Furthermore, the printed circuit board assembly 11 (PCBA) is connected to the display screen 12 via a connecting line 18, and is used to realize functions such as circuit connection and signal transmission, receive various electrical signals and realize specific functions. The electrical signals include position voltage signals, interactive communication information, power supply signals, etc. transmitted by the potentiometer 21. The interactive communication information includes display menu information, cooking time information and other cooking information. The display screen 12 displays and adjusts the direction of the displayed information text according to the information received by the printed circuit board assembly 11.

[0037] Furthermore, the display screen 12 can be set as a display screen 12 that only has a display function and does not have a touch screen input function, or can be set as a display screen 12 that has both a display function and a touch screen input function. Accordingly, a touch area and a non-touch area can be set on the surface of the display screen 12. The non-touch area is used to display information, and the touch area is used to receive instructions and interact with the gas stove. The present application does not limit the area ratio of the display screen 12 on the main body 1 of the knob structure. For example, the area ratio of the display screen 12 to the top of the main body 1 can be 1:1 or 1:2. The area of ​​the display screen 12 can only occupy a part of the top surface of the main body 1, such as the display screen 12 occupies the top of the main body 1. The entire surface of the top of the main body 1 can also be set as the display screen 12. Similarly, the area ratio of the touch area and the non-touch area can also be adjusted according to needs, which will not be repeated here.

[0038] The embodiment of the utility model arranges a display screen and a printed circuit board assembly connected to the display screen in the knob structure, so that the display screen on the knob can display interactive information, and electrically connects the printed circuit board assembly and the mounting portion so that electrical signals sent by other components can be transmitted to the printed circuit board assembly. For example, the position signal of the position indicator can be transmitted to the printed circuit board assembly through the mounting portion, so that the text display direction on the display screen can be adjusted according to the position of the main body, thereby further enriching the function of the knob, realizing the interactivity of the knob in the mechanical valve gas stove, and improving the intelligence level of the knob's interactive function.

[0039] In some embodiments, the position indicator is a potentiometer 21 , and there is a linear relationship between the voltage of the potentiometer 21 and the rotation angle of the main body 1 .

[0040] Optionally, the position indicator may be an absolute encoder or a potentiometer. Figure 4 As shown, the potentiometer 21 is provided with three pins, the resistance values ​​at both ends of the potentiometer 21 are fixed, and the resistance value of the middle pin to any end pin is variable. The relationship between the rotation angle of the potentiometer 21 and the voltage of the potentiometer 21 includes a linear relationship, an exponential relationship, and a logarithmic relationship. In this embodiment, a potentiometer 21 with a linear relationship is adopted, so that the rotation angle of the main body can be regularly reflected by voltage changes, thereby realizing the control of the text display direction of the interactive information on the display screen.

[0041] The embodiment of the utility model adopts a potentiometer with a linear relationship between the rotation angle and the voltage as the position indicator of the knob structure. It can obtain the position change of the main body of the knob structure through the voltage relationship, thereby sending a position signal to the printed circuit board assembly, so that the processing module therein adjusts the display direction of the interactive information text on the display screen according to the position signal, stabilizes the display direction in a direction suitable for reading, improves the stability of the direction of the knob displaying the interactive information text, and improves the convenience of the interactive function of the mechanical valve knob.

[0042] In some embodiments, a signal receiving device 22 for relaying signals is disposed on the mounting portion.

[0043] like Figure 1 As shown, the potentiometer 21 includes a rotating portion 212 and a fixed portion 211. The fixed portion 211 is fixed on the valve body 4 of the gas valve. Optionally, it can be fixed by screw connection through a screw hole 2111. The signal receiving device 22 is arranged on the rotating portion 212 of the potentiometer. One end of the connecting wire 18 is connected to the signal receiving device 22 through the rotating portion 212, and the other end can be connected to the power supply and the potentiometer (not shown in the figure), and is used to receive signals sent by devices such as the power supply and the potentiometer. The power supply comes from the stove power board or the transfer control board. The signal receiving device 22 collects the signal and transmits it to the printed circuit board assembly 11.

[0044] The embodiment of the utility model can collect signals sent by other devices on one device by providing a signal receiving device, and transmit the signals together, thereby saving line layout, simplifying line design, and reducing product cost.

[0045] In some embodiments, a first socket portion 111 is disposed on the bottom surface of the printed circuit board assembly 11 , and a second socket portion 221 is disposed on the signal receiving device 22 , and the first socket portion 111 and the second socket portion 221 match each other.

[0046] Furthermore, the shapes of the first socket portion 111 and the second socket portion 221 are respectively shapes that can match each other. The first socket portion 111 and the second socket portion 221 are matched by plugging into each other. After the signal receiving device 22 receives the signal transmitted by each device, the signal is transmitted to the printed circuit board assembly 11, so that the printed circuit board assembly 11 controls the direction of the text information on the display screen 12 according to the potentiometer position signal; and displays corresponding interactive information on the display screen 12, such as fire power, cooking time, etc. The user can control the cooking time according to the information on the display screen 12.

[0047] It should be noted that, since the rotation angle of the mechanical valve stem 3 is not large, generally the rotation angle range is 180°, this method is simple to power and communicate, does not require complex wireless power supply or active contact power supply, and only uses ordinary socket power supply and communication.

[0048] The embodiment of the utility model sets a first socket part on the printed circuit board assembly of the main body and sets a second socket part on the signal receiving device, so that the first socket part and the second socket part can match each other, and transmit the signal to be transferred received at the signal transmission device to the printed circuit board assembly, so as to realize the transmission of interactive information, enable the display screen to adjust the direction of text display according to the potentiometer position signal, improve the flexibility and readability of the interactive information display on the knob, and eliminate the obstacle of changing the rotation angle of the knob to reading the interactive information on the display screen. By connecting the second socket part to the power supply, the printed circuit board assembly and the display screen can be powered, and ordinary socket power supply communication is adopted, which simplifies the power supply scheme and reduces the product cost.

[0049] In some embodiments, the potentiometer includes a fixed portion 211 and a rotating portion 212 , the fixed portion 211 is fixedly connected to the valve body 4 of the cooker, and the rotating portion 212 is rotatably connected to the fixed portion 211 .

[0050] Based on the principle of the potentiometer, it is necessary to change the relative position between the fixed part 211 and the rotating part 212 to change the resistance to obtain different voltages. Therefore, the potentiometer is provided with a fixed part 211 and a rotating part 212. The fixed part 211 is fixed to the stove valve body 4, and the rotating part 212 rotates to achieve resistance adjustment.

[0051] In some embodiments, the potentiometer is provided with a through hole, the shape of the through hole matches the shape of the valve stem 3 of the stove, the valve stem 3 of the stove passes through the through hole and is fixedly connected to the rotating part 212, and the valve stem 3 is rotatably connected to the fixed part 211.

[0052] Based on the principle of the potentiometer, the fixed part 211 of the potentiometer needs to be fixed on the stove valve body 4, and the valve stem 3 is fixedly connected to the rotating part 212. When the main body 1 is rotated, the main body 1 drives the valve stem 3 to rotate, and then drives the rotating part 212 of the potentiometer to rotate, so that a relative displacement is generated between the rotating part 212 and the fixed part 211, so that the rotation angle of the valve stem 3 is equal to the rotation angle of the main body 1.

[0053] Furthermore, there is a linear relationship between the voltage and the rotation angle of the potentiometer, so that the position signal represented by the voltage of the potentiometer can accurately reflect the rotation angle of the main body 1, thereby determining the position of the knob.

[0054] The embodiment of the utility model sets the fixed part of the potentiometer on the gas valve body of the stove, rotates the rotating part to adjust the resistance of the potentiometer to generate different voltages, and fixes the valve stem and the rotating part so that the rotation angle of the main body can be transmitted to the rotating part through the valve stem. The potentiometer can reflect the position signal representing the main body according to the rotation angle, and transmits the position signal to the printed circuit board assembly, thereby providing a reliable basis for adjusting the direction of displayed text on the display screen. Based on this, the display direction of the text on the display screen can be adjusted in time with the change of the knob angle, so that the text can always be displayed in a direction that conforms to reading habits, thereby improving the intelligence of the knob structure, enhancing the interactivity of the knob structure, improving the user experience, and improving the convenience of reading the text on the display screen.

[0055] In some embodiments, a waterproof structure is disposed on the second socket portion 221 .

[0056] To prevent liquid from penetrating from the surface of the cooker into the knob structure and causing malfunction or danger, the socket is waterproofed. For example, after the receiving structure 131 is arranged at the bottom of the second socket part 221, glue can be applied for waterproofing, or a sealant can be embedded in the receiving structure 131 for waterproofing.

[0057] The embodiment of the utility model improves the waterproofness and safety of the knob structure by providing a waterproof structure, avoids interference with the signal connection between the printed circuit board assembly and the power supply, potentiometer and other devices, reduces the possibility of failure of the interactive function of the knob structure, and further improves the stability of the interactive function of the knob structure.

[0059] In some embodiments, the containing structure 131 is a semi-enclosed hole, which is closed at one end close to the display screen 12 and open at one end away from the display screen 12. The shape of the semi-enclosed hole matches the shape of the valve stem 3. One end of the valve stem 3 is placed inside the valve body 4 of the stove, and the other end of the valve stem 3 is fixedly connected to the semi-enclosed hole.

[0060] As mentioned above, the main body 1 and the valve stem 3 are fixedly connected, and the bottom plate 13 of the main body 1 is provided with a containing structure 131, which matches the valve stem 3, and is a semi-closed hole. The present application does not restrict the shape of the containing structure 131. By way of example, the cross-sectional shape of the hole can be a D-shaped hole, a square hole, a conical hole, etc. The cross-sectional shape of the hole matches the cross-sectional shape of the valve stem 3, so that the valve stem 3 can be clamped in the containing structure 131. By rotating the main body 1, the valve stem 3 can be driven to rotate together, thereby realizing the physical linkage between the main body 1 and the valve stem 3, wherein the cross-section refers to a cross-section on any plane perpendicular to the central axis of the hole or the valve stem 3.

[0061] The embodiment of the utility model provides a semi-enclosed containing structure on the bottom plate of the main body, and the shape of the containing structure matches the shape of the valve stem, and one end of the valve stem is fixed in the containing structure, so that the main body and the valve stem are detachably fixed to each other, and rotating the main body drives the valve stem to rotate, thereby achieving control of the firepower, maintaining the detachable feature of the mechanical valve stove, and improving the convenience of repair and maintenance of the stove.
