Description

[0001] This application is a divisional application of the patent application filed on July 19, 2021, with application number 202110815546.2 and invention title "Material Weighing Assembly and Kitchen Cooking Apparatus". Technical Field

[0002] This invention relates to the field of cooking equipment technology, and in particular to a material weighing assembly and a kitchen cooking device. Background Technology

[0003] As people's living standards continue to improve, their demand for healthy eating is increasing. For example, in order to maintain their weight and control their intake of nutrients such as carbohydrates, especially at dinner, people usually strictly control the amount of rice they eat, and instead eat more fruits, vegetables, and whole grains.

[0004] In most cases, rice is cooked in a rice cooker. To control the amount of rice cooked, people usually rely on experience or use a graduated measuring cup to determine the amount of rice to put into the rice cooker. However, relying on experience is prone to error, resulting in inconsistent amounts of rice, which fails to meet people's needs for precise control of rice intake to ensure a healthy diet. While using a graduated measuring cup can ensure that the amount of rice cooked each time is within a preset value, the process of inserting the measuring cup into the rice bag is highly random. Sometimes more or less rice is added, requiring frequent observation and comparison of the actual amount of rice with the marked lines to adjust the amount of rice. This is cumbersome, time-consuming, and laborious, affecting cooking efficiency. Summary of the Invention

[0005] In view of this, the present invention provides a material weighing assembly and a kitchen cooking device to solve the problems in the prior art that the material cannot be accurately weighed, the operation is time-consuming and labor-intensive, and the cooking efficiency is affected.

[0053] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention.

They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0055] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0056] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0057] Example 1

[0058] like Figures 1 to 3 The image shows a material weighing assembly according to the first embodiment of this application, comprising: a pot 10, an upper shell 20, a display component 30, a lower shell 40, and a weighing component 50. The pot 10 is used to hold materials to be cooked and can cook the materials thoroughly after being heated. For example, the materials can be, but are not limited to, rice, meat, seafood, etc. In this embodiment, if rice is used, the pot 10 can cook the rice into cooked rice after being heated.

[0059] The cookware 10 is made of metal or alloy to achieve higher and more uniform heat transfer efficiency, thereby improving rice cooking efficiency. The cookware 10 is shaped like a cylinder with an open top and a closed bottom for easy installation and removal.

[0060] Please continue reading. Figure 3 The cookware 10 is disposed within the upper housing 20, which includes an abutment portion 21. Specifically, the upper housing 20 includes a base, which is a circular plate. The abutment portion 21 is a circular plate protruding downward from the bottom surface of the base.

[0061] The display component 30 is disposed on the upper housing 20 and is used to display the weight of the material contained in the pot 10; the upper housing 20 is disposed on the lower housing 40; the weighing component 50 is disposed on the lower housing 40, and one end of the weighing component 50 abuts against the contact part 21, and the other end is used to abut against the platform supporting the weighing module; the weighing component 50 is electrically connected to the display component 30.

[0062] In summary, implementing the embodiments of the present invention will have the following beneficial effects: the material weighing assembly of the above solution, as an independent and complete component, can be installed in the heating base of a kitchen cooking device when food needs to be cooked, so as to heat the food. Specifically, during use and before being installed in the heating base, the material to be cooked is first placed in the pot 10. The weight of the material acts on the upper shell 20, and the weight of the upper shell 20 increases, causing it to sink downward relative to the lower shell 40, so that the contact part 21 presses the weighing component 50. The gravity of the material acts on the weighing component 50, and the weighing component 50 can accurately measure the weight value of the material. This weight value is transmitted to the display component 30 through the weighing component 50, thereby displaying the current weight value of the material in real time to the user, making it convenient for the user to intuitively and accurately control the amount of material added, thus facilitating the control of dietary intake. Compared to existing technologies, the material weighing assembly in this solution can accurately weigh the materials and present the weight to the user in numerical form. It has high weighing accuracy, is convenient and labor-saving to use, and solves the problem of users having difficulty and inaccuracy in controlling the amount of ingredients. At the same time, it helps to improve cooking efficiency and meet users' needs for healthy eating.

[0063] Understandably, the aforementioned floating gap is specifically an annular gap between the upper housing 20 and the lower housing 40. This annular gap provides the upper housing 20 with a downward travel distance so that after the material is placed in the pot 10, the upper housing 20 can move downward relative to the lower housing 40 and contact the weighing component 50, allowing the weighing component 50 to acquire the weight of the material.

[0064] Understandably, once the upper shell 20 and the pot 10 are manufactured, their weights are fixed. This fixed value is pre-stored in the weighing component 50, which can then calculate the weight of materials other than the upper shell 20 and the pot 10 by subtraction. This weighing method has a simple working principle, high accuracy, and fast result acquisition speed.

[0065] Please continue reading. Figure 1 and Figure 3In this embodiment, the edge of the pot 10 extends outward to form a limiting flange 11, and the upper surface of the upper shell 20 is provided with a support portion 26, to which the limiting flange 11 is fastened. Thus, by fastening the limiting flange 11 to the support portion 26, the pot 10 can be securely placed on the upper shell 20, and this movable assembly relationship also allows the pot 10 to be easily disassembled for cleaning at any time.

[0066] Of course, in other embodiments, the cookware 10 can also be fixed to the upper housing 20 by other installation methods in the prior art, such as snap-fit ​​connection or magnetic connection.

[0067] Please continue reading. Figure 1 and Figure 3 In some embodiments, the weighing component 50 includes a weighing sensor 51 and a weighing control board 52. The weighing sensor 51 is disposed on the lower housing 40 and can abut against the contact part 21. The weighing sensor 51 and the display component 30 are electrically connected to the weighing control board 52. When rice is put into the pot 10, the increased weight of the pot 10 will press down the upper housing 20, causing the contact part 21 to press against the weighing sensor 51, allowing the weighing sensor 51 to accurately weigh the rice. The weighed weight value is transmitted to the weighing control board 52, which converts the weight value into digital form and displays it on the display component 30. The user can then intuitively see the weight of the rice currently being loaded, thus enabling effective control.

[0068] Please continue reading. Figure 2 Preferably, at least two load cells 51 are provided, and the at least two load cells 51 are arranged circumferentially on the lower housing 40, and the at least two load cells 51 can simultaneously abut against the contact part 21. This helps to improve the accuracy of weight detection and eliminates the interference of factors such as unstable placement of the cookware 10 on the measurement results.

[0069] Preferably, in this embodiment, four weighing sensors 51 are used and distributed at 90° intervals in the circumferential direction.

[0070] Please continue reading. Figure 2 Based on any of the above embodiments, a retaining member 60 is provided on the lower housing 40, and the retaining member 60 forms a retaining groove, in which the weighing sensor 51 is snapped. Snapping the weighing sensor 51 into the retaining groove ensures that the weighing sensor 51 is securely installed and will not loosen or shift, thus affecting its detection capability.

[0071] In the above embodiment, the locking component 60 is specifically a semi-enclosed box-shaped structure, with an opening on its top surface and one of its sides that are connected. This allows the load cell 51 to be easily inserted into or removed from the slot from either the horizontal or vertical direction, making installation and removal convenient and effortless.

[0072] Of course, in other embodiments, the weighing sensor 51 can also be assembled and fixed to the lower housing 40 by any other method in the prior art, such as screwing, bonding, welding, or snap-fit ​​connection.

[0073] In addition, in order to ensure that the weighing control plate 52 is securely installed on the lower housing 40, a positioning structure 70 is provided on the lower housing 40, and the weighing control plate 52 is fixed on the positioning structure 70.

[0074] Please continue reading. Figure 3 For example, in this embodiment, the positioning structure 70 includes at least two positioning supports 71 and at least two fasteners 72. The weighing control plate 52 is disposed on the positioning supports 71, and the fasteners 72 are snap-fitted to the weighing control plate 52. The at least two positioning supports 71 are spaced apart but close to each other, and the weighing control plate 52 is placed directly on the top surface of the positioning supports 71. The positioning supports 71 support and fix the weighing control plate 52. On this basis, at least two fasteners 72 fasten the upper surface of the weighing control plate 52 from above. At this time, the fasteners 72 and the positioning supports 71 restrict the degree of freedom of the weighing control plate 52 from the upper and lower sides to ensure that the weighing control plate 52 is installed firmly and is not easy to loosen or fall off.

[0075] Preferably, the weighing control plate 52 is rectangular, and four positioning supports 71 are provided in a rectangular arrangement. Different positioning supports 71 support each corner of the weighing control plate 52, thereby improving the stability of the support.

[0076] In addition, the top surface of the positioning support 71 is recessed with a right-angle step, and the four corner parts of the weighing control plate 52 are respectively inserted into the corresponding right-angle steps, so that the horizontal movement freedom of the weighing control plate 52 is constrained, further ensuring the stable installation of the weighing control plate 52.

[0077] Please continue reading. Figure 3 Furthermore, based on any of the above embodiments, the upper housing 20 is provided with a positioning mating post 22, and the lower housing 40 is provided with a positioning mating platform 41. The positioning mating platform 41 forms a positioning mating groove, and the positioning mating post 22 is movably inserted into the positioning mating groove. The positioning mating post 22 inserted into the positioning mating groove makes the upper housing 20 and the lower housing 40 more reliably positioned and connected.

[0078] Furthermore, to avoid interference with the downward floating of the upper housing 20, the positioning and fitting post 22 is made of an elastic material; or the end of the positioning and fitting post 22 has an elastic part, which is inserted into the positioning and fitting groove. That is, when rice is put into the pot 10 and the upper housing 20 moves downward, the positioning and fitting post 22 or the elastic part can deform to avoid it, the floating gap can be reduced smoothly, the contact part 21 can press smoothly against the weighing sensor 51, and the weight of the rice can be accurately measured.

[0079] Please continue reading. Figure 3 In some embodiments, the upper housing 20 is provided with a mounting cavity 23 and a window 24 communicating with the mounting cavity 23. The display component 30 is disposed within the mounting cavity 23, and the display portion of the display component 30 is opposite to the window 24. This allows the user to directly observe the weight of the rice after weighing.

[0080] The upper housing 20 is also provided with a movable pressing plate 25, which is correspondingly arranged with the input section of the display component 30. For example, the input section can be a mechanical button or a touch screen, allowing users to perform functions such as "zeroing" and "memory", enriching the usability of the material weighing assembly and improving the user experience and convenience.

[0081] In addition to the above, this application also provides a kitchen cooking device, which may be, but is not limited to, a rice cooker, an electric pressure cooker, etc.

[0082] The kitchen cooking apparatus includes a heating base and a material weighing assembly as described above, wherein the material weighing assembly is detachably disposed within the heating base.

[0083] The heating base has the ability to heat the material weighing assembly so that rice can be cooked into cooked rice. The material weighing assembly can be used as a detachable independent unit component, which is convenient for assembly and disassembly, and it can also be assembled and used with different types of heating bases.

[0084] Example 2

[0085] like Figures 4 to 7 As shown, any of the above embodiments including Embodiment 1 are included, but the difference from Embodiment 1 is that the upper housing 20 is disposed on the lower housing 40, and a floating gap 80 is formed between the upper housing 20 and the lower housing 40. The lower housing 40 is provided with a bearing step 41. The display component 30 is disposed on the bearing step 41. One end of the weighing component 50 is connected to the upper housing 20, and the other end is connected to the lower housing 40. The weighing component 50 is electrically connected to the display component 30.

[0086] In summary, implementing the embodiments of the present invention will have the following beneficial effects: The material weighing assembly of the above solution, as an independent and complete component, can be installed in the heating base of the cooking appliance when food needs to be cooked, so as to heat the food. Specifically, during use and before being installed in the heating base, the material to be cooked is first placed in the pot 10. The weight of the material acts on the upper shell 20, and the weight of the upper shell 20 increases, causing it to move downward relative to the lower shell 40. The distance of the floating gap 80 decreases, so that the upper shell 20 abuts against the weighing component 50 pre-installed on the platform step. The weighing component 50 senses the pressure and can accurately measure the weight value of the material. This weight value is transmitted to the display component 30 through the weighing component 50, thereby displaying the current weight value of the material in front of the user, making it convenient for the user to intuitively and accurately control the amount of material added, thus facilitating the control of food intake. Compared to existing technologies, the material weighing assembly in this solution can accurately weigh the materials and present the weight to the user in numerical form. It has high weighing accuracy, is convenient and labor-saving to use, and solves the problem of users having difficulty and inaccuracy in controlling the amount of ingredients. At the same time, it helps to improve cooking efficiency and meet users' needs for healthy eating.

[0087] Understandably, the aforementioned floating gap 80 is specifically an annular gap between the upper housing 20 and the lower housing 40. This annular gap provides the upper housing 20 with a downward travel distance so that after the material is placed in the pot 10, the upper housing 20 can move downward relative to the lower housing 40 and contact the weighing component 50, allowing the weighing component 50 to acquire the weight of the material.

[0088] Furthermore, the outer periphery of the upper housing 20 is provided with a limiting groove extending toward the lower housing 40, and the outer periphery of the bearing step 41 is provided with a limiting insert extending toward the upper housing 20. The limiting insert is inserted into the limiting groove, and the limiting insert is in clearance fit with the bottom of the limiting groove. Inserting the limiting insert into the limiting groove facilitates a more secure assembly of the upper housing 20 and the lower housing 40, resulting in higher overall structural stability of the weighing assembly. The length of the limiting insert is designed to be less than the depth of the limiting groove, so that the end of the limiting insert maintains a clearance fit with the bottom of the limiting groove. This allows it to accommodate the floating gap 80 and avoids interference with the downward movement of the upper housing 20 after rice is added to the pot 10.

[0089] Example 3

[0090] like Figures 8 to 13As shown, any of the above embodiments, including examples, differ in that the display component and the weighing control board are integrated into one unit, namely the display and control component. This component is mounted on the supporting step and is used to measure and display the weight of the material contained in the pot. In this embodiment, the weighing sensor 50 includes a connecting base 51, a sensing body 52, and a connecting arm 53. The connecting base 51 and the connecting arm 53 are respectively connected to opposite ends of the sensing body 52. ​​The connecting base 51 is connected to the upper housing 20, and the connecting arm 53 is connected to the lower housing 30. Therefore, by connecting the connecting base 51 to the upper housing 20 and the connecting arm 53 to the lower housing 30, the weighing sensor 50 can be simultaneously assembled and fixed to both the upper housing 20 and the lower housing 30. When the upper housing 20 moves downward relative to the lower housing 30, the sensing body 52 undergoes bending deformation. The amount of bending deformation corresponds to the generation of a weight signal, which can be fed back to the weighing control board and ultimately presented to the user by controlling the indicator light to illuminate or by digital display.

[0091] Specifically, the inner pot weighing unit further includes a first fastener 90 and a second fastener 100. The connecting seat 51 has a first mounting hole, and the upper housing 20 has a second mounting hole opposite to the first mounting hole. The first fastener 90 passes through and is fixed in the first and second mounting holes. The connecting arm 53 has a third mounting hole, and the lower housing 30 has a fourth mounting hole opposite to the third mounting hole. The second fastener 100 passes through and is fixed in the third and fourth mounting holes. For example, both the first fastener 90 and the second fastener 100 are screws. One of the corresponding first and second mounting holes is a through hole, and the other is a threaded hole. Similarly, one of the third and fourth mounting holes is a through hole, and the other is a threaded hole. In this way, after the screw passes through the through hole, it is locked into the corresponding threaded hole, thus realizing the assembly connection between the connecting seat 51 and the upper housing 20, and between the connecting arm 53 and the lower housing 30. This screw-connection assembly method has a simple structure, high connection strength, and convenient and labor-saving assembly and disassembly operations.

[0092] Preferably, at least two load cells 50 are provided, and the at least two load cells 50 are arranged circumferentially on the supporting step 31, and the at least two load cells 50 can simultaneously abut against the bottom surface of the upper housing 20. This helps to improve the accuracy of weight detection and eliminates the interference of factors such as unstable placement of the cookware 10 on the measurement results.

[0093] Preferably, in this embodiment, four weighing sensors 50 are used and distributed at 90° intervals in the circumferential direction.

[0094] Based on any of the above embodiments, a locking member 60 is provided on the bearing step 31. The locking member 60 has a locking hole with a telescopic notch in the hole wall. The load cell 50 has a locking post that is engaged in the locking hole. Engaging the load cell 50 in the locking hole ensures its stable installation, preventing it from loosening or shifting and affecting its detection capability. Furthermore, the telescopic notch in the hole wall allows for the installation of locking posts with a diameter slightly larger than the hole diameter, thereby improving the applicability of the locking member 60 to load cells 50 with locking posts of different diameters.

[0095] In the above embodiment, the locking component 60 is specifically a semi-enclosed cylindrical structure with an opening on its top surface and one of its side surfaces, for example, a C-shape. This allows the load cell 50 to be easily inserted into or removed from the locking hole from either the horizontal or vertical direction, making installation and removal convenient and effortless.

[0096] Of course, in other embodiments, the weighing sensor 50 can also be assembled and fixed to the lower housing 30 by any other method in the prior art, such as screwing, bonding, welding, or snap-fit ​​connection.

[0097] In addition, in order to ensure that the weighing control board is securely installed on the lower housing 30, a positioning structure 70 is provided on the bearing step 31, and the display and control component 40 is fixed on the positioning structure 70.

[0098] For example, in this embodiment, the positioning structure 70 includes a first locking plate 71 and a second locking plate 72 spaced apart and opposite to each other, and the display control component 40 is fitted between the first locking plate 71 and the second locking plate 72. Since the distance between the first locking plate 71 and the second locking plate 72 is adapted to the length of the display control component 40, the first locking plate 71 and the second locking plate 72 can hold the display control component 40 from two opposite directions, thereby restricting the degree of freedom of the display control component 40 and ensuring that the display control component 40 is installed firmly and is not easy to loosen or fall off.

[0099] Preferably, the first clamping plate 71 and the second clamping plate 72 are formed in an inverted L shape. In addition to clamping the side of the display and control component 40, they can also press the display and control component 40 from above, further restricting the degree of freedom of the display and control component 40 and making the installation of the display and control component 40 more stable and reliable.

[0100] Furthermore, based on any of the above embodiments, the outer periphery of the upper shell 20 is provided with a limiting hole extending toward the lower shell 30, and the outer periphery of the bearing step 31 is provided with a limiting insert extending toward the upper shell 20. The limiting insert is inserted into the limiting hole, and the limiting insert and the bottom of the limiting hole are in clearance fit. Inserting the limiting insert into the limiting hole facilitates a more secure assembly of the upper shell 20 and the lower shell 30, resulting in higher overall structural stability of the inner pot weighing unit. The length of the limiting insert is designed to be less than the depth of the limiting hole, so that the end of the limiting insert and the bottom of the limiting hole maintain a clearance fit, thereby adapting to the floating gap 80 and avoiding interference with the downward movement of the upper shell 20 after rice is added to the pot 10.

[0101] Example 4

[0102] like Figures 14 to 17 As shown, the material weighing assembly includes a pot 10, an upper shell 20, a middle shell 20a, a lower shell 30, a display and control component 40, and a weighing sensor 50. The pot 10 is used to hold the material to be cooked and can cook the material after being heated. For example, the material can be, but is not limited to, rice, meat, seafood, etc. In this embodiment, if rice is used as the material, the pot 10 can cook the rice into cooked rice after being heated.

[0103] The cookware 10 is made of metal or alloy to achieve higher and more uniform heat transfer efficiency, thereby improving rice cooking efficiency. The cookware 10 is shaped like a cylinder with an open top and a closed bottom for easy installation and removal.

[0104] The cookware 10 is disposed within the upper housing 20. Specifically, the upper housing 20 includes a base, which is a circular plate. The inner ring wall of the base has an annular protrusion protruding towards the lower housing 30. The main structure of the lower housing 30 also has an annular plate, and the annular protrusion can be inserted into the inner ring cavity of the annular plate and abut against the inner wall of the inner ring cavity, so as to achieve the assembly and positioning of the upper housing 20 and the lower housing 30, and the assembly is stable.

[0105] The middle shell 20a is connected to the upper shell 20; the lower shell 30 is disposed on the side of the middle shell 20a away from the upper shell 20, and the lower shell 30 is connected to the upper shell 20, with a floating gap 70 formed between the middle shell 20a and the lower shell 30; the display and control component 40 is disposed on the middle shell 20a and connected to the upper shell 20, and the display and control component 40 is used to measure and display the weight of the material contained in the pot 10; the weighing sensor 50 is disposed on the upper shell 20, and the weighing sensor 50 is connected to the lower shell 30, and the weighing sensor 50 is electrically connected to the display and control component 40.

[0106] The material weighing assembly described above is an independent and complete component. When food needs to be cooked, it can be installed into the heating base of the cooking equipment to heat the food. Specifically, during use and before being installed into the heating base, the material to be cooked is first placed in the pot 10. The weight of the material acts on the upper shell 20 and the middle shell 20a. The total weight of the upper shell 20 and the middle shell 20a increases, causing them to move downward relative to the lower shell 30. The distance of the floating gap 70 decreases. Since the weighing sensor 50 is connected to the upper shell 20 and the lower shell 30 respectively, when the upper shell 20 and the middle shell 20a move relative to the lower shell 30, the weighing sensor 50 will undergo bending deformation. The degree of bending deformation can directly correspond to the weight of the material. That is, the weighing sensor 50 can accurately measure the weight value of the material, and this weight value will be transmitted to the display and control component 40. The display and control component 40 will display the current weight value of the material in front of the user, making it convenient for the user to intuitively and accurately control the amount of material added, thereby facilitating the control of food intake. Compared to existing technologies, the material weighing assembly in this solution can accurately weigh the materials and present the weight to the user in numerical form. It has high weighing accuracy, is convenient and labor-saving to use, and solves the problem of users having difficulty and inaccuracy in controlling the amount of ingredients. At the same time, it helps to improve cooking efficiency and meet users' needs for healthy eating.

[0107] Understandably, the upper housing 20 and the middle housing 20a constitute an integral housing assembly, and the aforementioned floating gap 70 is specifically an annular gap between this housing assembly and the lower housing 30. This annular gap provides the downward travel of the housing assembly so that after the material is placed in the pot 10, the housing assembly can move downward relative to the lower housing 30 and contact the weighing sensor 50 to trigger it, allowing the weighing sensor 50 to acquire the weight of the material.

[0108] Understandably, once the upper shell 20, the middle shell 20a, and the pot 10 are manufactured, their weights are fixed. This fixed value is pre-stored in the display and control component 40, which can calculate the weight of materials other than the upper shell 20 and the pot 10 by subtraction. This weighing method has a simple working principle, high accuracy, and fast result acquisition speed.

[0109] The material weighing assembly also includes a battery 100, which is disposed on the middle housing 20a and electrically connected to the display and control component 40. The battery 100 supplies power to the display and control component 40, ensuring that the material weighing assembly can operate reliably for extended periods.

[0110] In this embodiment, the edge of the pot opening of the cookware 10 extends outward to form a limiting flange 11, and the upper surface of the upper shell 20 is provided with a support portion 23, to which the limiting flange 11 is fastened. Thus, by fastening the limiting flange 11 to the support portion 23, the cookware 10 can be securely placed on the upper shell 20, and this movable assembly relationship also allows the cookware 10 to be easily disassembled for cleaning at any time.

[0111] Of course, in other embodiments, the cookware 10 can also be fixed to the upper housing 20 by other installation methods in the prior art, such as snap-fit ​​connection or magnetic connection.

[0112] In some embodiments, the display and control component 40 includes a weighing control board, an indicator light 42, and a button 43, both of which are electrically connected to the weighing control board. When rice is placed into the pot 10, the increased weight of the pot 10 causes the upper shell 20 to move downwards. During this process, the weighing sensor 50 bends and deforms, generating a detection value. The weighing sensor 50 can then accurately measure the weight of the rice. The measured weight value is transmitted to the weighing control board, which converts the weight value into digital form and displays it on the indicator light 42. The user can then intuitively see the weight of the rice currently placed in the pot, thus enabling effective control.

[0113] In some embodiments, the weighing sensor 50 in this embodiment includes a connector 51, a first sensing element 52, a second sensing element 53, a first connecting arm 54, and a second connecting arm 55. The first sensing element 52 and the second sensing element 53 are respectively connected to opposite ends of the connector 51. The first connecting arm 54 is connected to the end of the first sensing element 52 away from the connector 51, and the second connecting arm 55 is connected to the end of the second sensing element 53 away from the connector 51. The connector 51 is connected to the upper housing 20, and the first connecting arm 54 and the second connecting arm 55 are respectively connected to the lower housing 30.

[0114] Therefore, by connecting the upper housing 20 to the connector 51, and by connecting the first connecting arm 54 and the second connecting arm 55 to the lower housing 30, the weighing sensor 50 can be assembled and fixed to both the upper housing 20 and the lower housing 30. When the upper housing 20 and the middle housing 20a move downward relative to the lower housing 30, the first sensing element 52 and the second sensing element 53 will simultaneously undergo bending deformation. The amount of bending deformation corresponds to the generation of a weight signal, which can be fed back to the weighing control board and ultimately presented to the user by controlling the indicator light 42 to light up or by displaying the signal digitally.

[0115] Specifically, the material weighing assembly includes a first fastener 80, the connecting body 51 has a first mounting hole, and the upper housing 20 includes a handle box 24 with a second mounting hole opposite to the first mounting hole. The first fastener 80 passes through and is fixed in both the first and second mounting holes. For example, the first fastener 80 can be a screw, with the first mounting hole being a through hole and the second mounting hole being a threaded hole. Thus, after the screw passes through the through hole, it is locked into the corresponding threaded hole, thereby achieving the assembly connection between the connecting body 51 and the upper housing 20. This screw-connection assembly method has a simple structure, high connection strength, and is convenient and labor-saving for assembly and disassembly.

[0116] Furthermore, the material weighing assembly also includes a second fastener 90, the middle housing 20a includes a handle plate 21a, the handle plate 21a has a through hole 211a, the lower housing 30 is provided with a connecting post 32, the connecting post 32 passes through the through hole 211a, the connecting post 32 has a third mounting hole, the handle box 24 has a fourth mounting hole opposite to the third mounting hole, and the second fastener 90 is fixed by passing through the third mounting hole and the fourth mounting hole.

[0117] Similarly, for example, if the second fastener 90 is a screw, the corresponding third mounting hole is a through hole, and the fourth mounting hole is a threaded hole. Thus, after the screw passes through the through hole, it is locked into the corresponding threaded hole, thereby achieving the assembly connection between the lower housing 30 and the upper housing 20. This screw-connection assembly method has a simple structure, high connection strength, and is convenient and labor-saving for assembly and disassembly.

[0118] Understandably, the handle plate 21a and the handle box 24 are combined to form a handle, which makes it convenient for users to lift and pick up the material weighing assembly.

[0119] Preferably, in this embodiment, the weighing sensor 50, the connecting column 32, the handle plate 21a, the handle box 24, the first fastener 80, and the second fastener 90 are all provided in pairs and assembled and connected one-to-one. This symmetrical installation of two weighing sensors 50 helps improve the weighing accuracy of materials. Furthermore, the two handles allow the user to operate the material weighing assembly with both hands, making it safer and more efficient.

[0120] The handle plate 21a has a recessed receiving groove 212a on the side facing the handle box 24, and the weighing sensor 50 is inserted into the receiving groove 212a. The weighing sensor 50 is installed in the receiving groove 212a, which can avoid interference with the handle box 24, and at the same time help to reduce the overall thickness of the handle, so as to realize the miniaturization design of the material weighing assembly.

[0121] It should be noted that the number of weighing sensors 50 in this embodiment can also be three, four or more, depending on the actual needs. For example, when there are four weighing sensors 50, the four weighing sensors 50 are distributed at 90° intervals in the circumferential direction of the middle housing 20a.

[0122] In addition, in order to ensure that the weighing sensor 50 is securely installed on the middle housing 20a, the middle housing 20a also includes a carrier plate 22a, on which a positioning structure 60 is provided, and the display and control component 40 is fixed on the positioning structure 60.

[0123] Example 5

[0124] like Figures 18 to 21 As shown, the difference from Embodiment 4 is that the material weighing assembly includes: a pot 10, an upper shell 20, a lower shell 30, a display panel 40, a weighing control panel 50, and a weighing sensor 60. Please continue reading. Figure 4 The cookware 10 is disposed within the upper housing 20, which includes a handle box 22; the lower housing 30 includes a handle plate 33, the upper housing 20 is disposed on the lower housing 30, and a floating gap 80 is formed between the upper housing 20 and the lower housing 30; the display panel 40 and the weighing control panel 50 are used to be installed on the heating base or the heating cover, and the display panel 40 is used to display the weight of the material contained in the cookware 10; the weighing sensor 60 is disposed on the handle plate 33, and the weighing sensor 60 is connected to the handle box 22 and electrically connected to the weighing control panel 50.

[0125] During use, before being placed into the heating element, the food to be cooked is first placed into the pot 10. The weight of the food acts on the upper shell 20, increasing its weight and causing it to move downward relative to the lower shell 30. The distance of the floating gap 80 decreases. Since the weighing sensor 60 is connected to the handle plate 33 and the handle box 22 respectively, when the upper shell 20 moves relative to the lower shell 30, the weighing sensor 60 will undergo bending deformation. The degree of bending deformation directly corresponds to the weight of the food, meaning that the weighing sensor 60 can accurately measure the weight of the food. This weight value is then transmitted to the weighing control board 50, which transmits the weight value to the display board 40. Finally, the display board 40 displays the current weight value of the food in front of the user, allowing the user to intuitively and accurately control the amount of food added, thereby facilitating the control of dietary intake. Compared to existing technologies, the material weighing assembly in this solution can accurately weigh the materials and present the weight to the user in numerical form. It has high weighing accuracy, is convenient and labor-saving to use, and solves the problem of users having difficulty and inaccuracy in controlling the amount of ingredients. At the same time, it helps to improve cooking efficiency and meet users' needs for healthy eating.

[0126] The upper housing 20 has an annular plate 23 on its bottom surface facing the lower housing 30, and the lower housing 30 has an annular step 34 on its top surface facing the upper housing 20. The annular plate 23 is inserted into the annular step 34. In this way, the annular plate 23 and the annular step 34 are nested together, which restricts the degree of freedom of the upper housing 20 and the lower housing 30 in the horizontal plane, thereby helping to ensure that the upper housing 20 and the lower housing 30 are assembled stably.

[0127] Example 6

[0128] like Figures 22 to 24 As shown, the material weighing assembly includes: a pot 10, a supporting shell assembly, a weight transfer frame assembly 200, a lower shell 30, a display and control component 40, and a weighing sensor 50. The pot 10 is used to hold the material to be cooked and can cook the material after being heated. For example, the material can be, but is not limited to, rice, meat, seafood, etc. In this embodiment, if rice is used as the material, the pot 10 can cook the rice into cooked rice after being heated.

[0129] The supporting shell assembly includes an upper shell 20 and a lower shell 30. The cookware 10 is disposed within the upper shell 20. Specifically, the upper shell 20 includes a shell base, which is a circular plate. The inner ring wall of the shell base has an annular protrusion extending downward toward the lower shell 30. The main structure of the lower shell 30 also has an annular plate, and the annular protrusion can be inserted into the inner ring cavity of the annular plate and abut against the inner wall of the inner ring cavity, so as to achieve the assembly and positioning of the upper shell 20 and the lower shell 30, and the assembly is stable.

[0130] The cookware 10 is mounted on the supporting shell assembly, and the supporting shell assembly has a clearance portion. In this embodiment, the cookware 10 is disposed inside the upper shell 20, the middle shell 20a is connected to the upper shell 20, and the middle shell 20a has a clearance portion. The weighing sensor 50 is disposed on the supporting shell assembly; the lower shell 30 is spaced apart from the middle shell 20a on the side opposite to the upper shell 20; the weight transfer frame assembly 200 is detachably disposed on the lower shell 30, and the weight transfer frame assembly 200 is detachably connected to the weighing sensor 50 through the clearance portion, and a floating gap 70 is formed between the weight transfer frame assembly 200 and the middle shell 20a; the display and control component 40 is disposed on the middle shell 20a and connected to the upper shell 20, the weighing sensor 50 is electrically connected to the display and control component 40, and the display and control component 40 is used to display the weight of the material contained in the cookware 10.

[0131] The load-bearing housing assembly is designed to include an upper housing 20 and a middle housing 20a, so that the upper housing 20 and the middle housing 20a can cooperate to form an installation cavity for mounting the load cell 50.

[0132] In summary, implementing the embodiments of the present invention will have the following beneficial effects: The detachable material weighing module of the above-described solution, as an independent and complete component, can be installed into the heating base of a rice cooker when food cooking is required, so as to heat and cook the food until it is cooked. Specifically, during use and before being installed into the heating base, the material to be cooked is first placed in the pot 10, and the weight of the material acts on the supporting shell assembly, namely the upper shell 20 and the middle shell 20a; the total weight of the upper shell 20 and the middle shell 20a increases and moves downward relative to the lower shell 30, and the distance of the floating gap 70 becomes smaller. Since the weighing sensor 50 is connected to the upper shell 20 and the weight transmission frame assembly 200 respectively, and the weight transmission frame assembly 200 is fixedly installed on the lower shell 30, when the upper shell 20 and the middle shell 20a move relative to the lower shell 30, The weighing sensor 50 undergoes bending deformation, and the degree of bending deformation directly corresponds to the weight of the material. This means the weighing sensor 50 can accurately measure the weight of the material, and this weight value is transmitted to the display and control component 40, which displays the current weight of the material to the user. This allows the user to intuitively and accurately control the amount of material added, thus facilitating the control of dietary intake. Furthermore, since the weighing frame assembly 200, the lower housing 30, and the weighing sensor 50 are detachably connected, they can be easily disassembled and cleaned after cooking. Compared to existing technologies, this detachable material weighing module can accurately weigh the material and present the weight numerically to the user. It offers high weighing accuracy, is convenient and labor-saving, solves the problem of users having difficulty and inaccurate control over the amount of food used, and improves cooking efficiency, meeting users' needs for healthy eating.

[0133] Understandably, the upper shell 20 and the middle shell 20a constitute an integral shell assembly, i.e., a load-bearing shell assembly. The aforementioned floating gap 70 is specifically an annular gap between this shell assembly and the lower shell 30. This annular gap provides the downward travel of the shell assembly so that after the material is placed in the pot 10, the shell assembly can move downward relative to the lower shell 30 to contact and trigger the weighing sensor 50, allowing the weighing sensor 50 to acquire the weight of the material.

[0134] Understandably, once the upper shell 20, the middle shell 20a, and the pot 10 are manufactured, their weights are fixed. This fixed value is pre-stored in the display and control component 40, which can calculate the weight of materials other than the upper shell 20 and the pot 10 by subtraction. This weighing method has a simple working principle, high accuracy, and fast result acquisition speed.

[0135] Optionally, in this embodiment, the weighing sensor 50 is a bridge sensor or other weighing device with equivalent technical effects.

[0136] In this embodiment, the edge of the pot opening of the cookware 10 extends outward to form a limiting flange 11, and the upper surface of the upper shell 20 is provided with a support portion 23, to which the limiting flange 11 is fastened. Thus, by fastening the limiting flange 11 to the support portion 23, the cookware 10 can be securely placed on the upper shell 20, and this movable assembly relationship also allows the cookware 10 to be easily disassembled for cleaning at any time.

[0137] Of course, in other embodiments, the cookware 10 can also be fixed to the upper housing 20 by other installation methods in the prior art, such as snap-fit ​​connection or magnetic connection.

[0138] In some embodiments, the load transfer frame assembly 200 includes a first load transfer bracket 210 and a second load transfer bracket 220 disposed at intervals on opposite sides of the lower housing 30. Two load cells 50 are provided, each correspondingly disposed on the first load transfer bracket 210 and the second load transfer bracket 220. This uniform and symmetrical distribution of the two load cells 50 allows for simultaneous and synchronized measurement of the material within the cookware 10, improving measurement accuracy.

[0139] The outer wall of the lower housing 30 is provided with a carrier rod 32, and the first load-bearing bracket 210 is provided with a hook plate 211, which is hooked and connected to the carrier rod 32. The carrier rod 32 is fixed to the lower housing 30 by two oppositely arranged plate seats, which is reliable and stable. The hook plate 211 is hooked and connected to the carrier rod 32, which is simple to install, reliable, and more convenient and labor-saving to install and remove than the screw connection method.

[0140] In addition, the outer wall of the lower housing 30 is provided with a fastener 33, and a locking bracket 34 is provided on the fastener 33. The locking bracket 34 has a hook groove, and the second load-transfer bracket 220 has a hook rod 221, which is hooked and disposed in the hook groove. The fastener 33 is integrally fixed to the outer wall of the lower housing, and the connection is reliable. The locking bracket 34 is connected to the fastener 33 through the upwardly curved hook at the bottom, which is convenient for assembly and disassembly. Then, the hook rod 221 is inserted into the hook groove, which realizes the indirect connection between the second load-transfer bracket 220 and the lower housing. This connection method is simple and is more convenient and labor-saving for assembly and disassembly compared with the screw connection method.

[0141] Example 7

[0142] like Figures 25 to 29 As shown, the material weighing assembly includes: a pot 10, a bearing shell assembly, a weight transmission bracket 200, a lower shell 30, a display and control component 40, a first magnetic suction component 300, a second magnetic suction component 400, and a weighing sensor 50. The pot 10 is used to hold the material to be cooked and can cook the material thoroughly after being heated.

[0143] The cookware 10 is mounted on the supporting shell assembly, and the supporting shell assembly has a clearance portion. In this embodiment, the cookware 10 is disposed inside the upper shell 20, the middle shell 20a is connected to the upper shell 20, and the middle shell 20a has a clearance portion. Specifically, the upper shell 20 includes a shell base, which is a circular plate. The inner ring wall of the shell base has a ring-shaped protrusion protruding towards the lower shell 30. The main structure of the middle shell 20a and the lower shell 30 also has a ring plate, and the ring protrusion can be inserted into the inner ring cavity of the ring plate and abut against the inner wall of the inner ring cavity, so as to realize the assembly and positioning of the upper shell 20, the middle shell 20a, and the lower shell 30, and the assembly is stable. The purpose of designing the supporting shell assembly to include the upper shell 20 and the middle shell 20a is that the upper shell 20 and the middle shell 20a can cooperate to form an installation cavity for mounting the weighing sensor 50.

[0144] The weighing sensor 50 is disposed on the supporting shell assembly; the display and control component 40 is disposed on the supporting shell assembly and electrically connected to the weighing sensor 50, and the display and control component 40 is used to display the weight of the material contained in the pot 10; the weight transfer bracket 200 is detachably connected to the weighing sensor 50 through the clearance part, and a floating gap 70 is formed between the weight transfer bracket 200 and the supporting shell assembly; the first magnetic suction member 300 is disposed on the weight transfer bracket 200; the lower shell 30 is detachably disposed below the weight transfer bracket 200; and the second magnetic suction member 400 is disposed on the lower shell 30, and the second magnetic suction member 400 is detachably magnetically connected to the first magnetic suction member 300.

[0145] In summary, implementing the embodiments of the present invention will have the following beneficial effects: the material weighing assembly of the above-described solution, as an independent and complete component, can be installed into the heating base of a kitchen cooking device when food cooking is required, so as to heat and cook the food until it is cooked. Specifically, during use and before being installed into the heating base, the material to be cooked is first placed in the pot 10, and the weight of the material acts on the supporting shell assembly, namely the upper shell 20 and the middle shell 20a; the total weight of the upper shell 20 and the middle shell 20a increases and moves downward relative to the lower shell 30, and the distance of the floating gap 70 becomes smaller. Since the weighing sensor 50 is connected to the upper shell 20 and the weight transmission frame assembly respectively, and the weight transmission frame assembly is fixedly installed on the lower shell 30, when the upper shell 20 and the middle shell 20a move relative to the lower shell 30, the weighing sensor 50 will undergo bending deformation. The degree of bending deformation can directly correspond to the weight of the material, that is, the weighing sensor The weighing assembly 50 can accurately measure the weight of the material, and this weight value is transmitted to the display and control component 40. The display and control component 40 displays the current weight value of the material in front of the user, allowing the user to intuitively and accurately control the amount of material added, thereby facilitating the control of dietary intake. In addition, since the first magnetic suction component 300 is installed on the weighing support 200 and the second magnetic suction component 400 is installed on the lower shell 30, and the first magnetic suction component 300 is magnetically connected to the second magnetic suction component 400, the weighing support 200 can be quickly disassembled from the lower shell 30 after cooking, allowing the cookware 10, the supporting shell assembly, and the weighing support 200 to be removed together for easy cleaning. Compared with the prior art, the material weighing assembly of this solution can accurately weigh the material and present the weight numerically to the user. It has high weighing accuracy, is convenient and labor-saving to use, solves the problem of users having difficulty and inaccuracy in controlling the amount of ingredients, improves cooking efficiency, meets users' needs for healthy eating, and is also easy to clean, ensuring health and hygiene.

[0146] Understandably, the upper shell 20 and the middle shell 20a constitute an integral shell assembly, i.e., a load-bearing shell assembly. The aforementioned floating gap 70 is specifically an annular gap between this shell assembly and the lower shell 30. This annular gap provides the downward travel of the shell assembly so that after the material is placed in the pot 10, the shell assembly can move downward relative to the lower shell 30 to contact and trigger the weighing sensor 50, allowing the weighing sensor 50 to acquire the weight of the material.

[0147] Understandably, once the upper shell 20, middle shell 20a, and pot 10 are manufactured, their weights are fixed. This fixed value is pre-stored in the display and control component 40, which can calculate the weight of materials other than the upper shell 20 and pot 10 by subtraction. This weighing principle is simple, accurate, and fast. Optionally, in this embodiment, the weighing sensor 50 uses a bridge sensor or other weighing devices with equivalent technical effects.

[0148] The material weighing assembly also includes a battery 100, which is disposed on the middle housing 20a and electrically connected to the display and control component 40. The battery 100 supplies power to the display and control component 40, ensuring that the material weighing assembly can operate reliably for extended periods.

[0149] In this embodiment, the edge of the pot 10 extends outward to form a limiting flange 11, and the upper surface of the upper shell 20 is provided with a support portion 23, to which the limiting flange 11 is fastened. Thus, by fastening the limiting flange 11 to the support portion 23, the pot 10 is securely placed on the upper shell 20, and this movable assembly also allows the pot 10 to be easily removed for cleaning. Of course, in other embodiments, the pot 10 can also be fixed to the upper shell 20 using other existing installation methods such as snap-fit ​​connections or magnetic connections.

[0150] In some embodiments, the material weighing assembly further includes a magnet holder 500, which is disposed on the load transfer bracket 200. The first magnetic suction member 300 is disposed on the magnet holder 500. The lower housing 30 is provided with a lifting plate 32, and a fixing groove 321 is recessed on the side of the lifting plate 32 facing the load transfer bracket 200. The second magnetic suction member 400 is embedded in the fixing groove 321. Therefore, the first magnetic suction member 300 can be installed and fixed to the load transfer bracket 200 by the magnet holder 500, and the second magnetic suction member 400 can be snapped and fixed in the fixing groove 321. Both the first magnetic suction member 300 and the second magnetic suction member 400 are stably installed, which helps to ensure the reliability of their magnetic connection or separation. Optionally, both the first magnetic suction member 300 and the second magnetic suction member 400 are magnets.

[0151] Furthermore, the magnet holder 500 is provided with a first slot and a second slot arranged opposite to each other. The first magnetic member 300 is fitted into the first slot, and the portion of the second magnetic member 400 extending out of the fixing groove 321 is fitted into the second slot. The first magnetic member 300 and the second magnetic member 400 are close to each other and magnetically connected. By fitting the first magnetic member 300 into the first slot and the second magnetic member 400 into the second slot, the first magnetic member 300 and the second magnetic member 400 can achieve magnetic connection at the closest possible distance in a non-contact state. This is beneficial for improving the magnetic fixing strength and reliability, while avoiding excessive magnetic force that would make subsequent disassembly of the load transfer bracket 200 and the lower housing 30 difficult.

[0152] In some embodiments, the load transfer bracket 200 has insertion holes, and the magnet fixing bracket 500 has first insertion pins 510, which are inserted into the insertion holes. Thus, the load transfer bracket 200 and the magnet fixing bracket 500 adopt a simple insertion-connection method and structure, ensuring reliable connection and convenient assembly and disassembly. Specifically, in this embodiment, three first insertion pins 510 are arranged at even intervals along the circumference in the same plane, and correspondingly, three insertion holes are also provided, each corresponding to one of the first insertion pins 510, which further enhances the connection strength between the magnet fixing bracket 500 and the load transfer bracket 200.

[0153] Furthermore, the magnet holder 500 is also provided with a second pin 520, which is inserted into the fixing groove 321. The second pin 520 is locked with the groove wall of the fixing groove 321, thereby realizing the assembly and fixation of the magnet holder 500 and the lower shell. This connection method has a simple structure and is easy to assemble and disassemble.

[0154] In some embodiments, the display and control component 40 includes a weighing control board, an indicator light 41, and a button 42, both electrically connected to the weighing control board. When rice is placed into the pot 10, the increased weight of the pot 10 causes the upper shell 20 and the middle shell 20a to move downwards. During this process, the weighing sensor 50 undergoes bending deformation and generates a detection value, allowing the weighing sensor 50 to accurately measure the weight of the rice. The measured weight value is transmitted to the weighing control board, which converts the weight value into digital form and displays it on the indicator light 41. The user can then intuitively see the weight of the rice currently placed in the pot, thus enabling effective control.

[0155] In some embodiments, the weighing sensor 50 in this embodiment includes a connector 51, a first sensing element 52, a second sensing element 53, a first connecting arm 54, and a second connecting arm 55. The first sensing element 52 and the second sensing element 53 are respectively connected to opposite ends of the connector 51. The first connecting arm 54 is connected to the end of the first sensing element 52 away from the connector 51, and the second connecting arm 55 is connected to the end of the second sensing element 53 away from the connector 51. The connector 51 is connected to the upper housing 20. The first connecting arm 54 is connected to the first load-transmitting bracket 200 and the second load-transmitting bracket 200, and the second connecting arm 55 is connected to the first load-transmitting bracket 200 and the second load-transmitting bracket 200.

[0156] Therefore, by connecting the upper housing 20 to the connector 51, and by connecting the first connecting arm 54 and the second connecting arm 55 to the first and second load transfer brackets 200, the weighing sensor 50 can be simultaneously assembled and fixed to the upper housing 20 and the lower housing 30. When the upper housing 20 and the middle housing 20a move downward relative to the lower housing 30, the first sensing element 52 and the second sensing element 53 will simultaneously undergo bending deformation. The amount of bending deformation corresponds to the generation of a weight signal, which can be fed back to the weighing control board and ultimately presented to the user by controlling the indicator light 41 to light up or by displaying it digitally.

[0157] Specifically, the material weighing assembly includes a first fastener 80, the connecting body 51 has a first mounting hole, and the upper housing 20 includes a handle box 24 with a second mounting hole opposite to the first mounting hole. The first fastener 80 passes through and is fixed in both the first and second mounting holes. For example, the first fastener 80 can be a screw, with the first mounting hole being a through hole and the second mounting hole being a threaded hole. Thus, after the screw passes through the through hole, it is locked into the corresponding threaded hole, thereby achieving the assembly connection between the connecting body 51 and the upper housing 20. This screw-connection assembly method has a simple structure, high connection strength, and is convenient and labor-saving for assembly and disassembly.

[0158] Furthermore, the material weighing assembly also includes a second fastener 90, the middle housing 20a includes a handle plate 21a, the handle plate 21a has a through hole 211a, the first weight transmission bracket 200 and the second weight transmission bracket 200 are both provided with connecting posts 210, the connecting posts 210 pass through the through hole 211a, the connecting posts 210 have a third mounting hole, the handle box 24 has a fourth mounting hole opposite to the third mounting hole, and the second fastener 90 is fixed by passing through the third mounting hole and the fourth mounting hole.

[0159] Similarly, for example, if the second fastener 90 is a screw, the corresponding third mounting hole is a through hole, and the fourth mounting hole is a threaded hole. Thus, after the screw passes through the through hole, it is locked into the corresponding threaded hole, thereby achieving the assembly connection between the lower housing 30 and the upper housing 20. This screw-connection assembly method has a simple structure, high connection strength, and is convenient and labor-saving for assembly and disassembly.

[0160] Understandably, the handle plate 21a and the handle box 24 are combined to form a handle, which makes it convenient for users to lift and pick up the material weighing assembly.

[0161] Furthermore, a recessed clearance is formed on the side of the handle plate 21a facing the handle box 24, and the head of the first fastener 80 is inserted into the recessed clearance. This avoids interference between the handle plate 21a and the first fastener 80, and prevents the handle plate 21a and the handle box 24 from being unable to be assembled and secured.

[0162] Preferably, in this embodiment, the weighing sensor 50, the connecting column 210, the handle plate 21a, the handle box 24, the first fastener 80, and the second fastener 90 are all configured in pairs and assembled and connected one-to-one. This symmetrical installation of two weighing sensors 50 improves the weighing accuracy of the material. The two handles allow the user to operate the material weighing assembly with both hands, making it safer and more efficient.

[0163] The handle plate 21a has a recessed receiving groove on the side facing the handle box 24, and the weighing sensor 50 is inserted into the receiving groove. The weighing sensor 50 is installed in the receiving groove, which can avoid interference with the handle box 24, and at the same time helps to reduce the overall thickness of the handle, realizing the miniaturization design of the material weighing assembly.

[0164] It should be noted that the number of weighing sensors 50 in this embodiment can also be three, four or more, depending on the actual needs. For example, when there are four weighing sensors 50, the four weighing sensors 50 are distributed at 90° intervals in the circumferential direction of the middle housing 20a.

[0165] In addition, in order to ensure that the weighing sensor 50 is securely installed on the middle housing 20a, the middle housing 20a also includes a carrier plate 22a, on which a positioning structure 60 is provided, and the display and control component 40 is fixed on the positioning structure 60.

[0166] For example, in this embodiment, the positioning structure 60 includes a first locking plate 61 and a second locking plate 62 spaced apart and opposite to each other. The display control component 40 includes a mounting base, which is fitted between the first locking plate 61 and the second locking plate 62. Since the distance between the first locking plate 61 and the second locking plate 62 is adapted to the length of the mounting base, the first locking plate 61 and the second locking plate 62 can hold the display control component 40 from two opposite directions, thereby restricting the degree of freedom of the display control component 40 and ensuring that the display control component 40 is securely installed and not easily loosened or fallen off.

[0167] Preferably, the first clamping plate 61 and the second clamping plate 62 are formed in an inverted L shape. In addition to clamping the side of the display and control component 40, they can also press the display and control component 40 from above, further restricting the degree of freedom of the display and control component 40 and making the installation of the display and control component 40 more stable and reliable.

[0168] Furthermore, the lower shell 30 is also provided with a covering plate 31, which is spaced out and covers the outside of the cookware 10, and the shape of the covering plate 31 is adapted to the shape of the cookware 10. Therefore, the covering plate 31 can prevent the cookware 10 from being directly exposed to the environment, and provides a certain degree of protection for the cookware 10. However, it should be noted that in order to avoid interference with the downward movement of the upper shell 20, the size of the covering plate 31 should be larger than the size of the cookware 10, so that a certain distance is formed between the covering plate 31 and the outer wall of the cookware 10.

[0169] The outer shell 31 is made of a heat-conducting material. When the material weighing assembly is installed in the heating base, the heat can be quickly conducted to the entire surface of the cookware 10 through the outer shell 31, so that the rice in the cookware 10 is heated evenly and efficiently, which helps to improve cooking efficiency.

[0170] In some embodiments, the upper housing 20 has a lamp hole 21 and a button hole 22. The display lamp 41 of the display and control component 40 passes through the lamp hole 21, and the button 42 of the display and control component 40 passes through the button hole 22. When the upper housing 20 and the lower housing 30 are assembled, the lamp hole 21 allows the display lamp 41 to pass through the upper housing 20, and the button hole 22 allows the button 42 to pass through the upper housing 20, thereby avoiding interference problems that could affect the normal assembly of the upper housing 20 and the lower housing 30.

[0171] For example, button 42 can be a mechanical button or a touch screen, allowing users to set functions such as "zeroing" and "memory", which enriches the usability of the material weighing assembly and improves the user experience and convenience.

[0172] In addition to the above, this application also provides a kitchen cooking device, which may be, but is not limited to, a rice cooker, an electric pressure cooker, etc.

[0173] The kitchen cooking apparatus includes a heating base and a material weighing assembly as described above, wherein the material weighing assembly is detachably disposed within the heating base.

[0174] The heating base has the ability to heat the material weighing assembly so that rice can be cooked into cooked rice. The material weighing assembly can be used as a detachable independent unit component, which is convenient for assembly and disassembly, and it can also be assembled and used with different types of heating bases.

[0175] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0176] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
