[0044] Example 1

[0045] Figure 1 A schematic diagram of a portion of the structure of a cooking appliance provided in an embodiment of the present invention is shown in FIG. Figure 1 As shown, this embodiment provides a cooking appliance, which includes a pot body, an inner pot 5, a lid, a temperature detection device, and a control device. The pot body is provided with a heating device for heating the inner pot 5. The upper end of the pot body is open and forms an inner pot access opening. The inner pot 5 is accommodated in the inner cavity of the pot body and is used to store food. The inner cavity of the inner pot 5 forms a cooking cavity. The lid body is pivotally connected to the upper end opening of the pot body for closing or opening the upper end opening. The lid body is provided with an operation panel. The operation panel includes a display screen and control buttons. The user selects the operating mode of the cooking appliance through the control buttons. The display screen is used to display control options and information such as the cooking process. The temperature detection device is used to detect the temperature of the food and / or water vapor in the inner pot 5. The control device is electrically connected to the heating device, the operation panel, and the temperature detection device, and is used to adjust the operation of the cooking appliance according to the user's selection of different operating modes.

[0046] In this embodiment, the cooking appliance is an electromagnetic heating rice cooker. A pot-shaped wire winding drum 1 is installed within the cooker body. The upper end of the wire winding drum 1 is open and supported by a support member at the upper periphery of the cooker body. The upper flange of the inner pot 5 is supported by the periphery of the support member. A storage space is formed between the wire winding drum 1 and the cooker body. A heating device is located within this storage space. The heating device comprises an electromagnetic coil wound around the wire winding drum 1. By energizing the electromagnetic coil, the inner pot 5, located within the magnetic field, heats up, thereby cooking the food.

[0047] In this embodiment, the cooking appliance is an electric rice cooker, but the present invention is not limited thereto. In other embodiments, the cooking appliance may also be an electric pressure cooker, an electric skillet, an electric soup pot, etc. Furthermore, in this embodiment, the configuration of the cooking appliance body, inner pot 5, lid, and control device can all be referenced in the prior art. This is not the focus of the present invention and will not be further described. The present invention will only describe the specific structure of the temperature control device.

[0048] Figure 2 is a structural diagram of the installation portion provided by an embodiment of the present invention, Figure 3 is a cross-sectional view of the cooking utensil provided by an embodiment of the present invention at a first viewing angle with the mounting member and the mounting portion not screwed together. Figure 4 is a cross-sectional view of the cooking utensil provided by an embodiment of the present invention at a first viewing angle with the mounting member and the mounting portion screwed together. Figure 5 is a schematic structural diagram of the cooking utensil provided by an embodiment of the present invention at a second viewing angle, such as Figure 2-5 As shown, the temperature detection device is disposed outside the inner pot 5 and is detachably connected to the wire winding drum 1. Specifically, the temperature detection device comprises a detachably connected mounting member 3 and a temperature detection assembly 2. The wire winding drum 1 is provided with a mounting portion 11 for mounting the temperature detection device. The mounting portion 11 is rotatably connected to the mounting member 3, and the mounting member 3 can be engaged or disengaged by rotating relative to the mounting portion 11. The temperature detection assembly 2 has a temperature sensing end, which passes through an avoidance through-hole 12 in the wire winding drum 1 and abuts against the outer wall of the inner pot 5 to detect the temperature of the inner pot 5.

[0049] The cooking utensil provided in this embodiment avoids the use of screws to connect the mounting member 3 and the wire winding drum 1 by arranging the mounting member 3 of the temperature detection device and the mounting portion 11 of the wire winding drum 1 in a rotationally fastened manner, thereby reducing material costs and avoiding the risk of screws falling into the cooking utensil. In addition, the use of a rotationally fastened manner to connect the mounting member 3 and the wire winding drum 1 makes installation simple and operation easy, thereby improving installation and disassembly efficiency.

[0050] Specifically, the mounting portion 11 has a screw-on surface 111 located on a screw-on circumference, with a first latching protrusion 112 protruding from the screw-on surface 111. The mounting member 3 is provided with a screw-on portion 35, which abuts against the screw-on surface 111 and can rotate relative to the screw-on surface 111 around the axis of the screw-on circumference. A first latching groove 351 is defined on the screw-on portion 35, and rotation of the screw-on portion 35 relative to the screw-on surface 111 can cause the first latching protrusion 112 to enter or exit the first latching groove 351. When the mounting member 3 rotates relative to the mounting portion 11 in the screw-on direction, the front end of the screw-on portion 35 passes over the first latching protrusion 112 under the extrusion deformation of the first latching protrusion 112, causing the first latching protrusion 112 to be latched in the first latching groove 351.

[0051] Furthermore, to facilitate the first protrusion 112 to enter the first slot 351, a guide slope 1121 is provided on the side of the first protrusion 112 facing the screwing direction. To prevent the first protrusion 112 from disengaging from the first slot 351, a limiting surface 1122 is provided on the side of the first protrusion 112 facing away from the screwing direction.

[0052] Furthermore, to limit further rotation of the mounting member 3 in the screwing direction after the first latching protrusion 112 enters the first latching groove 351, a stopper 113 is provided on the screwing surface 111. The first latching protrusion 112 and the stopper 113 are spaced apart in the screwing direction, and a second screwing groove 115 is formed between the first latching protrusion 112 and the stopper 113. A stopper groove 352 is formed on the screwing portion 35, extending through the front end of the screwing portion 35. The protrusion between the stopper groove 352 and the first latching groove 351 forms a second latching protrusion 353. When the mounting member 3 rotates relative to the mounting portion 11 in the screwing direction, the first latching protrusion 112 first enters the stopper groove 352. Then, by squeezing and deforming the second latching protrusion 353, it passes over the second latching protrusion 353 and enters the first latching groove 351. At this point, the second latching protrusion 353 is located in the second latching groove 115, and the stopper 113 is located in the stopper groove 352. The angle between the side surface of the anti-rotation portion 113 facing the screwing direction and the tangent line at the corresponding position of the screwing surface 111 is greater than or equal to 90°, and the anti-rotation groove 352 is adapted to the shape of the anti-rotation portion 113 .

[0053] In other embodiments, when the first locking protrusion 112 is engaged with the first locking groove 351, the anti-rotation portion 113 is located in the anti-rotation groove 352, which can further improve the fastening stability between the mounting member 3 and the mounting portion 11. In other embodiments, the anti-rotation portion 113 can also directly abut against the front end surface of the screwing portion 35 along the screwing direction to achieve the anti-rotation effect.

[0054] In order to prevent the mounting member 3 from separating from the anti-rotation portion 113 along its axial direction, a limiting portion 114 is protruded from the screw-on surface 111 at one end facing the mounting member 3. The limiting portion 114 is arranged in the axial direction of the mounting member 3 corresponding to the first protruding portion 112 and the anti-rotation portion 113. When the mounting member 3 and the mounting portion 11 are screwed into place, the screw-on portion 35 abuts against the side of the limiting portion 114 facing the inner pot 5.

[0055] In this embodiment, the mounting member 3 is provided with a receiving groove 36 for receiving the mounting portion 11. The outer wall of the mounting portion 11 is formed with the aforementioned screw-on surface 111, and the screw-on portion 35 is provided on the side of the receiving groove 36 facing the screw-on surface 111. In another embodiment, the end of the mounting portion 11 facing away from the inner pot 5 can be inserted into the receiving groove 36. The receiving groove 36 can be annular or arcuate, and the inner wall of the screw-on portion 11 forms the aforementioned screw-on surface. In another embodiment, the mounting portion 11 can be provided on the outer side of the mounting member 51.

[0056] In this embodiment, the mounting portion 11 is an arc-shaped structure, with two mounting portions 11 spaced apart in the circumferential direction of the central axis corresponding to the screw-on surface 111. The gap formed between two adjacent mounting portions 11 allows the screw-on portion 35 to be inserted between the two mounting portions 11. The number of screw-on portions 53 is the same as the number of mounting portions 11, and each screw-on portion 53 is rotationally engaged with the corresponding mounting portion 11. In another embodiment, the mounting portion 11 may be spaced apart by one, three, or more. In another embodiment, the mounting portion 11 may also be an annular structure, with multiple screw-on portions 53 rotationally engaged with the same mounting portion 11.

[0057] In this embodiment, the temperature detection device is positioned on the outer sidewall of the wire winding drum 1, and the distance between the temperature sensing end of the temperature detection device and the bottom of the inner pot 5 is 10 to 60 mm. This arrangement enables the temperature detection device to detect the temperature of the food in the inner pot 5 while also detecting the temperature of the steam within the inner pot 5. This avoids the need for both an upper temperature detection device on the lid for detecting steam and a lower temperature detection device on the bottom of the wire winding drum 1 for detecting the food within the inner pot 5, reducing the number of temperature detection devices required and the overall cost of the cooking appliance. Furthermore, positioning the temperature detection device on the side of the wire winding drum 1 avoids the need for holes in the bottom of the wire winding drum 1, not only improving the aesthetics of the internal structure but also better preventing water from entering the pot body, reducing the risk of water intrusion into the electrical components within the pot. Preferably, the distance between the temperature sensing end and the bottom of the inner pot 5 is 30 to 50 mm.

[0058] However, it is understandable that when the temperature detection device is arranged on the cover or at the bottom of the winding drum 1, the above-mentioned rotating buckle structure can also be used to realize the connection between the mounting portion 11 and the mounting member 3, which will not be described in detail in this embodiment.

[0059] Figure 6 is a schematic structural diagram of a temperature detection device provided by an embodiment of the present invention at one viewing angle, Figure 7 is a structural diagram of the temperature detection device provided by an embodiment of the present invention from another perspective, Figure 8: is a schematic diagram of the disassembled structure of the temperature detection device provided by an embodiment of the present invention, Figure 9 Schematic diagram of the structure of the mounting member 3 provided in an embodiment of the present invention. Figure 6-9 As shown, the temperature control device provided by the present invention includes a detachably connected temperature detection component 2 and a mounting component 3, the temperature detection component 2 is used to detect the temperature of the inner pot 5, and the mounting component 3 is used to fix the temperature detection component 2 relative to the inner pot 5.

[0060] Specifically, the temperature detection assembly 2 includes a sensor bracket 21, a sensor cover 22 and a temperature sensing unit. The first end of the sensor bracket 21 is detachably connected to the mounting member 3. The sensor cover 22 is arranged at the second end of the sensor bracket 21 and is detachably connected to the sensor bracket 21. A accommodating cavity 23 is formed between the sensor cover 22 and the sensor bracket 21. The temperature sensing unit is arranged in the accommodating cavity 23 and is fitted with the sensor cover 22. The sensor cover 22 is fitted with the inner pot 5. The temperature sensing unit is arranged in the accommodating cavity 23 and is used to detect the temperature of the inner pot 5.

[0061] In order to improve the temperature detection accuracy of the temperature sensing unit, the sensor bracket 21 and the sensor cover 22 are both made of metal material, and preferably, the sensor cover 22 and the sensor bracket 21 are made of aluminum material with good thermal conductivity to reduce detection errors.

[0062] In this embodiment, a receiving groove is defined on the end surface of the second end of the sensor bracket 21, opening toward the sensor cover 22. The temperature sensing unit is disposed in the receiving groove, and the sensor cover 22 seals the notch of the receiving groove to prevent the temperature sensing unit from detaching from the sensor bracket 21. In other embodiments, the sensor cover 22 may be provided with a receiving groove, and the second end surface of the sensor bracket 21 seals the notch of the receiving groove, thereby forming the aforementioned receiving cavity 23 with the groove wall of the receiving groove.

[0063] In this embodiment, the sensor bracket 21 includes a main column 211, and the sensor cover 22 includes a cylindrical portion 221 with one end open and the other closed. The inner diameter of the cylindrical portion 221 is equal to or slightly smaller than the outer diameter of the main column 211. The second end of the main column 211 is inserted into the cylindrical portion 221 through the opening and abuts against the bottom of the cylindrical portion 221. The bottom of the cylindrical portion 221 and the walls of the receiving groove together form the receiving cavity 23, and the outer wall of the bottom of the cylindrical portion 221 passes through the winding reel 1 and abuts against the inner pot 5.

[0064] To facilitate the connection between the sensor bracket 21 and the sensor cover 22, an annular flange 212 is formed on the outer circumferential wall of the main column 211. A retaining edge 213 is perpendicularly formed at the distal end of the flange 212, extending away from the sensor cover 22. Multiple retaining edges 213 are spaced apart along the circumference of the main column 211, with a clearance groove 215 formed between adjacent retaining edges 213. An extension 222 is radially outwardly formed at the open end of the sensor cover 22. Connecting portions 223 are formed at the distal end of the extension 222, extending toward the sensor bracket 21. Multiple connecting portions 223 are spaced apart along the circumference of the sensor cover 22. The flange 212 abuts the extension 222. The connecting portions 223 are located outside the retaining edge 213, and each connecting portion 223 corresponds to a clearance groove 215. When the sensor bracket 21 and the sensor cover 22 are installed in place, the connecting portion 223 is bent and inserted into the avoidance groove 215 so that the opposite sides of the flange portion 212 are respectively in contact with the extension portion 222 and the bent connecting portion 223, thereby fixing the sensor bracket 21 and the sensor cover 22.

[0065] The above-mentioned connection between the sensor bracket 21 and the sensor cover 22 is simple in structure, easy to process, and does not require screws. In other embodiments, other methods can also be used to connect the sensor bracket 21 and the sensor cover 22, such as a snap connection or a screw connection.

[0066] To prevent the temperature detection assembly 2 from failing or being damaged due to overheating of the inner pot 5, the temperature detection assembly 2 also includes a fuse disposed within the accommodating cavity 23. The fuse is connected in series with the temperature sensing unit in the temperature detection circuit and is used to disconnect the circuit if the current in the temperature detection circuit is excessive. Preferably, the fuse is disposed on the side of the temperature sensing unit away from the inner pot 5. This reduces the radial size of the accommodating cavity 23 along the sensor bracket 21, thereby reducing the radial size of the sensor bracket 21 and the sensor cover 22, reducing the overall size of the temperature detection assembly 2. This also significantly reduces the temperature difference between the upper and lower sides of the temperature detection assembly 2, enabling the temperature detection assembly 2 to collect better data and reflect the various temperatures of the inner pot 5.

[0067] Furthermore, the main column 211 is provided with threading holes along its axial direction, extending through opposite ends of the main column 211. External wires for the temperature sensing unit and fuse are routed through these holes to the exterior of the temperature detection assembly, facilitating connection to the control device within the pot. In this embodiment, four threading holes are provided at intervals to separate each wire for the temperature sensing unit and fuse, preventing entanglement of the external wires. In other embodiments, only one or two threading holes may be provided.

[0068] In this embodiment, the temperature sensing unit includes a thermistor. When the inner pot 5 is heated, the heat is transferred to the thermistor through the sensor cover 22, causing the thermistor's resistance to change, which in turn causes the current in the temperature detection circuit to change. The temperature of the inner pot 5 can be determined based on the change in current in the temperature detection circuit, resulting in high detection sensitivity. The placement of the thermistor and fuse are conventional in the art and will not be further described here.

[0069] The mounting member 3 includes a main body tube portion 31, which is provided with a mounting through-hole 311. The first end of the sensor bracket 21 is inserted into the mounting through-hole 311 and is removably connected to the mounting member 3. Specifically, a plurality of mounting bosses 313 are provided on the inner wall of the mounting through-hole 311, spaced apart along the circumference of the mounting through-hole 311. The inner sidewalls of the mounting bosses 313 are located on the same circumference, and the diameter of the circumference is equal to the outer diameter of the main body column portion 211. A protrusion 214 is provided on the circumferential wall of the first end of the main body column portion 211. The outer diameter of the protrusion 214 is equal to or slightly smaller than the inner diameter of the mounting through-hole 311. An escape channel 312 is formed between two adjacent mounting bosses 313 for the protrusion 214 to pass through.

[0070] The end of the mounting boss 313, away from the sensor cover 22, extends outward along the axis of the mounting hole 311 to form a limiting boss 314. A resilient arm 315 extends circumferentially from the extended end of at least one of the limiting bosses 314, with a gap between the resilient arm 315 and the end surface of the mounting hole 311. A limiting step 316 is provided on the side of the adjacent limiting boss 314, facing the direction of extension of the resilient arm 315, proximate to the resilient arm 315. The extended end of the resilient arm 315, the limiting step 316, and the side surface of the limiting boss 314 facing the extended end of the resilient arm 315 together form a receiving space for the protrusion 214.

[0071] When the sensor bracket 21 is installed with the mounting member 3, the main column 211 is inserted into the mounting hole 311 along the mounting hole 311 away from the elastic arm 315, and the protrusion 214 is located in the avoidance channel 312; when the protrusion 214 passes through the avoidance channel 312 and passes out of the mounting hole 311, the sensor bracket 21 is rotated so that the sensor bracket 21 rotates along the extension direction of the elastic arm 315. At this time, the elastic arm 315 is deformed under the squeezing action of the protrusion 214, so that the protrusion 214 passes over the elastic arm 315 along the side end face of the elastic arm 315 away from the sensor cover 22 and enters the accommodating position; the sensor bracket 21 moves along the axis so that the protrusion 214 abuts against the limiting step 316, and the opposite sides of the protrusion 214 abut against the limiting boss 314 and the elastic arm 315 respectively, preventing the sensor bracket 21 from continuing to rotate or rotating in the opposite direction.

[0072] Preferably, the distance between the elastic arm 315 and the corresponding end face of the mounting hole 311 gradually increases along the extension direction, so that the elastic arm 315 is inclined relative to the end face of the mounting hole 311, and the protrusion 214 slides along the elastic arm 315 away from the corresponding end face of the mounting hole 311.

[0073] In this embodiment, two protrusions 214 are symmetrically arranged along the axis of the main column portion 211, and four limiting bosses 314 are spaced apart along the circumference of the mounting hole 311. Two of the spaced limiting bosses 314 are provided with elastic arms 315, and the other two limiting bosses 314 are provided with limiting steps 316. In other embodiments, the number of protrusions 214 can be one or three, and the number of elastic arms 315 corresponds one-to-one with the number and location of the protrusions 214.

[0074] In order to limit the protruding position of the sensor bracket 21 relative to the mounting through hole 311, a side of the mounting plate portion 32 away from the elastic arm 315 forms an installation limit surface 321 for limiting the sensor bracket 21, and the end face of the retaining edge portion 213 can abut against the installation limit surface 321 to limit the maximum depth of the sensor bracket 21 inserted into the mounting through hole 311.

[0075] To ensure reliable contact between the temperature detection assembly 2 and the inner pot 5, the temperature detection device also includes an elastic member 4. This elastic member 4 is sleeved onto the main body column 211, with one end of the elastic member 4 resting against the flange 212 and the other end resting against the mounting boss 313. When the sensor bracket 21 and the mounting member 3 are properly installed, the elastic member 4 is compressed. As a result, the elastic force of the elastic member 4 allows the distal end of the sensor cover 22 to tightly contact the inner pot 5.

[0076] Furthermore, the main body tube portion 31 extends radially outward from one end face toward the sensor bracket 21 to form a mounting plate portion 32, and the mounting plate portion 32 is provided with an arc-shaped plate portion 34 coaxially arranged with the mounting through hole 311, and the inner side wall of the arc-shaped plate portion 34 is provided with the above-mentioned screw-on portion 35.

[0077] In order to avoid interference between the temperature detection component 2 and the winding reel 1, a limiting cylinder portion 33 coaxial with the mounting through hole 311 is protruded from one end of the mounting plate portion 32 toward the sensor cover 22, and the mounting limiting surface 321 is formed on the inner side of the limiting cylinder portion 33, and the retaining edge portion 213 is located on the inner side of the limiting cylinder portion 33, and the above-mentioned plug-in groove 36 is formed between the limiting cylinder portion 33 and the arc-shaped connecting portion 223.

[0078] In this embodiment, the mounting plate portion 32 is a D-shaped structure, and the two arc-shaped connecting portions 223 are respectively located at two ends of the mounting plate portion 32 for fool-proofing.

[0079] In this embodiment, the sensor bracket 21 is rotatably engaged with the main body tube 31. In other embodiments, the connection between the sensor bracket 21 and the main body tube 31 can also be a snap connection, a screw connection, or other connection forms, which will not be described here.

[0080] Example 2

[0081] This embodiment provides a cooking utensil. Compared with the first embodiment, the structure of the cooking utensil provided in this embodiment is basically the same as that of the first embodiment, and the only difference is the location of the temperature detection device. This embodiment will not repeat the same structure as the first embodiment.

[0082] In this embodiment, the temperature detection device is arranged on the insulation cover of the cooking utensil, and the insulation cover is provided with the above-mentioned mounting portion. The temperature detection device includes a connected mounting piece and a temperature detection component. The mounting piece is rotatably snap-fitted to the mounting portion, and the temperature detection component is used to detect the steam temperature in the cooking utensil.

[0083] The structure of the temperature detection device and the mounting portion can be configured similarly to that of Example 1 and will not be further described in this embodiment. Unlike Example 1, the detection end of the temperature detection device is positioned toward the inner pot, and the end of the mounting member, distal to the detection end, is rotatably engaged with the mounting portion. One end of the curved plate is connected to the mounting plate, while the other end extends away from the detection end. The screw-on portion is located at the extended end of the curved plate.

[0084] Furthermore, the cooking appliance provided in this embodiment is applicable not only to electromagnetic heating cooking appliances with a winding reel, but also to resistance heating cooking appliances.
