Thus, the appearances of the phrase "in one embodiment" or "in some embodiments" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0032] With reference to Figures 1 to 6 The utility model provides a kind of cooking utensil, comprising: shell 1, the through hole 11 is opened in the shell 1, the outer side of the shell 1 is equipped with waterproof rib 12 being arranged around the through hole 11;Knob assembly 2, including respectively being equipped with knob 21 and reading piece on the both sides of the shell 1, the reading piece passes through the through hole 11 and is connected with the knob 21, the side of the shell close to the knob 21 is equipped with recess 23 for the waterproof rib 12 to extend into.

[0033] With reference to Figures 1 to 5 In the utility model, shell 1 is one of the core structures of cooking utensil, mainly used to provide stable mounting platform for the knob 21, the reading piece and other components, to ensure that these components can work stably and reliably. At the same time, the shell 1 also plays the role of isolating external environment and preventing water from entering the cooking utensil. The through hole 11 is provided on the shell 1 for the reading piece to pass out, so as to realize the mechanical connection between the reading piece and the knob 21.

[0034] With reference to Figure 1 , Figure 2 , Figure 3 And Figure 6 Knob assembly 2 is a key component for controlling cooking utensil, and the user can control the heating temperature, heating time or heating mode of the cooking utensil by rotating the knob assembly 2. The knob 21 is arranged outside the shell 1 for the user to manually hold and rotate. The reading piece is arranged inside the shell 1 for reading the angular displacement of the knob 21 and converting it into an electrical signal. The reading piece can be an encoder 22, a potentiometer or a rotary sensor, and the specific type is not limited here.

[0035] In this embodiment, when water flows into the gap between the shell 1 and the knob 21, the waterproof rib 12 can block the water from flowing into the through hole 11, preventing water from entering the cooking utensil. After the waterproof rib 12 extends into the recess 23, it has a height higher than the gap between the shell 1 and the knob 21, which can completely block the gap between the shell 1 and the knob 21, achieving better waterproof effect.

[0036] Preferably, the diameter of the groove 23 is slightly larger than the outer diameter of the waterproof rib 12, which makes the gap between the waterproof rib 12 and the groove 23 as small as possible, ensuring the best waterproof effect, while the waterproof rib 12 does not contact the side wall of the groove 23, which does not affect the rotation of the knob 21.

[0037] Further, referring to Figure 2 With Figure 3 The outer side of the shell 1 is attached with a panel 3, and the panel 3 is provided with an opening 31 corresponding to the position of the through hole 11. The outer side of the shell 1 is provided with a glue groove 13 around the waterproof rib 12, and the glue groove 13 is coated with silicone glue. In this embodiment, the panel 3 is attached to the outer side of the shell 1 and located between the shell 1 and the knob 21, which can play a protective role for the shell 1, isolate high temperature, and avoid the shell 1 from being scalded and softened by high temperature food or being scratched by tableware. The opening 31 is used for the reading piece to pass through and mechanically connect with the knob 21, or for the knob 21 to pass through and mechanically connect with the reading piece, which is not limited here. Silicone glue is a kind of adhesive based on siloxane, which has stable bonding and sealing effects. The silicone glue is arranged in the glue groove 13, which is used for bonding the shell 1 and the panel 3 and preventing water from flowing into the gap between the shell 1 and the panel 3. When the silicone glue bonds the panel 3 and the shell 1, the silicone glue forms a glue wall around the waterproof rib 12. Even if water flows from the opening 31, the glue wall and the waterproof rib 12 can restrict the water between them, preventing the water from flowing along the surface of the shell 1, thereby preventing the water from flowing into the interior of the cooking appliance from the gap of the electric connection line, the button gap and the like of the shell 1. This design can further improve the waterproof performance.

[0038] Further, referring to Figure 2 With Figure 3The waterproof rib 12 is provided with a plurality of first protrusions 14 abutting against the bottom surface of the groove 23. Since the knob 21 is usually directly fixed to the reading part, due to tolerances and machining errors, the knob 21 will inevitably shake during use, affecting the user experience. In the embodiment, the first protrusions 14 enable the waterproof rib 12 to provide support to the knob 21, preventing the knob 21 from shaking. The side of the first protrusion 14 close to the bottom surface of the groove 23 is preferably arc-shaped, enabling the first protrusion 14 to point-contact with the knob 21, thereby reducing the friction between the first protrusion 14 and the knob 21, and avoiding excessive friction that makes it difficult for the knob 21 to rotate. The number of the first protrusions 14 is preferably at least three, and the at least three first protrusions 14 are preferably evenly arranged on the waterproof rib 12, so that the first protrusions 14 can support the knob 21 at least at three positions, thereby improving the stability of the knob 21. The first protrusions 14 can be arranged on the side of the waterproof rib 12 close to the knob 21, or on the side wall of the waterproof rib 12, which is not limited here.

[0039] In another embodiment, the first protrusions 14 are arranged on the bottom surface of the groove 23 and abut against the waterproof rib 12. The first protrusions 14 can also provide support to the knob 21, preventing the knob 21 from shaking.

[0040] Further, referring to Figure 3 and Figure 6 , the side of the knob 21 close to the shell 1 is provided with an inner ring 24, and the inner ring 24 is provided with a plurality of second protrusions 25 abutting against the shell 1. In the embodiment, the inner ring 24 can also improve the structural strength of the knob 21, preventing the knob 21 from deforming. The second protrusions 25 abut against the shell 1, enabling the shell 1 to provide support to the knob 21, further preventing the knob 21 from shaking. The side of the second protrusion 25 close to the shell 1 is preferably arc-shaped, which can reduce the friction between the second protrusion 25 and the shell 1, and avoid excessive friction that makes it difficult for the knob 21 to rotate. It should be noted that the second protrusions 25 can be arranged on the side of the inner ring 24 close to the shell 1, or on the side wall of the inner ring 24, which is not limited here.

[0041] In another embodiment, the second protrusions 25 are arranged on the outer side of the shell 1 and abut against the inner ring 24.

[0042] Further, referring to Figure 2 , Figure 3 andFigure 6 The reading part is provided as an encoder 22, and the shaft hole 26 is provided on one side of the knob 21 close to the shell 1. The rotating shaft 211 of the encoder 22 is inserted through the through hole 11 and the shaft hole 26. In this embodiment, the angular displacement of the knob 21 can be read by the encoder 22, and the angular displacement is converted into an electrical signal. The electrical signal can control multiple function modules in the cooking appliance. The user can adjust multiple function parameters by rotating the knob 21. Compared with buttons, the operation is more convenient and fast. The encoder 22 can also monitor the rotation angle and position of the knob 21 in real time, and provide high-precision data feedback. In the cooking process, accurate control is crucial. Whether it is adjusting the fire, temperature, or cooking time, the encoder 22 can provide detailed feedback to help users achieve the desired cooking effect. In addition, the encoder 22 can not only detect the rotation position, but also monitor the rotation speed. This means that when the user adjusts the knob 21, they can adjust the degree of adjustment by changing the rotation speed. For example, fast rotation can quickly adjust the temperature or time, while slow rotation can fine-tune. This flexibility greatly enhances the user experience. The knob 21 and the encoder 22 are directly connected through the shaft hole 26 and the rotating shaft 211 without additional transmission parts, so that the encoder 22 can quickly and accurately convert the rotation of the knob 21 into an electronic signal to realize real-time feedback.

[0043] Further, referring to Figure 3 and Figure 6 , the knob 21 is provided with a connecting rod 27 on one side close to the shell 1, and the shaft hole 26 is provided on the connecting rod 27. The knob 21 is provided with an oil groove 28 arranged around the connecting rod 27, and the oil groove 28 is used to accommodate lubricating oil. In this embodiment, when the oil groove 28 contains lubricating oil and the knob 21 is assembled with the encoder 22, the lubricating oil can flow along the connecting rod 27 to the rotating shaft 211, and then flow along the rotating shaft 211 to the position of the through hole 11. During the rotation of the knob 21 by the user, the lubricating oil can be evenly applied, thereby reducing the rotational friction between the rotating shaft 211 and the through hole 11 through the lubricating oil, making the rotation of the knob 21 smoother, and also reducing wear and improving service life. It can be understood that the connecting rod 27 not only guides the lubricating oil, but also allows the shaft hole 26 to have a greater depth, making the insertion of the shaft hole 26 and the rotating shaft 211 more stable, thereby improving the connection stability between the knob 21 and the encoder 22. Moreover, the connecting rod 27 and the rotating shaft 211 are simple and convenient to disassemble, which is convenient for the user to disassemble the knob 21 and add the lubricating oil.

[0044] Further, referring to Figure 2The inner side of the shell 1 is provided with a control circuit board, and the encoder 22 is welded on the control circuit board. In this embodiment, the control circuit board and the encoder 22 are connected without additional wires, which reduces the number and complexity of components, helps to improve the compactness of the overall structure, saves the internal space of the cooking utensil, and integrates the control circuit board and the encoder 22, without the need for assembly and wiring, simplifying the assembly process, reducing the assembly difficulty, improving the assembly efficiency, and facilitating maintenance. In addition, the encoder 22 is directly connected to the control circuit board, enabling the encoder 22 to quickly and accurately transmit feedback data to the control circuit board, reducing delay and ensuring real-time response.

[0045] Further, referring to Figure 4 and Figure 5 The inner side of the shell 1 is provided with a fixing member for fixing the control circuit board, which includes one or more of a screwing structure 16, a positioning structure 17, and a buckle structure 18. In this embodiment, the shell 1 fixes the control circuit board through the screwing structure 16, the positioning structure 17, or the buckle structure 18, which can ensure that the control circuit board and the encoder 22 are fixed stably in an integrated structure and do not shift or shake during use. On this basis, the inner diameter of the through hole 11 is slightly larger than the outer diameter of the rotating shaft 211 of the encoder 22, so that the rotating shaft 211 can pass through the through hole 11 and be limited by the through hole 11, ensuring that the rotating shaft 211 does not shift, thereby avoiding the problem that the rotating shaft 211 rotates irregularly due to the shift of the rotating shaft 211, causing the knob 21 to jam. Specifically, the screwing structure 16 includes studs provided on the shell 1 and mounting holes provided on the control circuit board, and screws pass through the mounting holes and connect with the studs; the positioning structure 17 includes a plurality of positioning blocks provided on the shell 1, and the positioning blocks abut against the control circuit board; the buckle structure 18 includes a plurality of buckles provided on the shell 1 and a plurality of buckle holes provided on the control circuit board, and the buckles are buckled on the edges and the buckle holes of the control circuit board; the control circuit board is provided with mounting holes corresponding to the screwing structure 16, and screws pass through the mounting holes to connect the control circuit board and the shell 1.

[0046] It should be noted that the shell 1 and the control circuit board can be fixed by one or more of the screwing structure 16, the positioning structure 17, and the buckle structure 18, which is not limited in detail.

[0047] Further, referring to Figure 2 and Figure 4The control circuit board is arranged as a display panel 15, and the housing 1 is provided with an opening window 19 corresponding to the position of the display element of the display panel 15. In the embodiment, the display panel 15 is an important component of the cooking appliance and is mainly used to display data related to the cooking process in real time. These data include the current heating temperature, the remaining heating time, the cooking mode, etc., so that the user can accurately control the cooking process and ensure that the cooking effect of the food reaches the best state. In addition, the display panel 15 can also provide real-time feedback. For example, when the user adjusts the heating temperature, the display panel 15 can immediately update the current temperature, so that the user can clearly understand the change of the setting. By arranging the opening window 19 on the housing 1, the information on the display panel 15 can be clearly visible, and the user can conveniently read the display content.

[0048] It should be noted that the display element of the display panel 15 can be a liquid crystal display screen, a light-emitting diode, or a digital tube, and the specific implementation is not limited herein.

[0049] Further, the cooking appliance is arranged as an induction cooker. In the embodiment, the induction cooker is a kitchen appliance that uses the principle of electromagnetic induction to heat the pot. It uses alternating current through the coil to generate an alternating magnetic field with a constantly changing direction. The conductor inside the alternating magnetic field will generate eddy currents. The Joule heating effect of the eddy current makes the pot body warm up, thereby achieving heating.

[0050] The above is only an optional embodiment of the present application, and does not limit the patent scope of the present application.
