[0002] During the cooking process of a double-boiler cooking appliance, when the heating device of one pot is working or the food in one pot is at high temperature, it will affect the temperature of the other pot and lid, which will cause inaccurate temperature measurement by the temperature measuring device in the cooking appliance.

[0003] Therefore, it is necessary to provide a cooking appliance to at least partially solve the above problems. Utility Model Content

[0004] The Summary of the Utility Model introduces a series of simplified concepts that will be further described in the Detailed Description of the Utility Model. The Summary of the Utility Model of the Utility Model does not intend to limit the key features and essential technical features of the claimed technical solution, nor does it intend to determine the scope of protection of the claimed technical solution.

[0005] In order to at least partially solve the above problems, the present invention provides a cooking utensil, comprising:

[0006] A pot body, wherein two pot inner parts are provided in the pot body;

[0063] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with embodiments of the present invention.

[0064] In this document, ordinal numbers such as "first" and "second" cited in the present invention are merely identifiers and do not have any other meanings, such as a specific order, etc. Moreover, for example, the term "first component" itself does not imply the existence of a "second component", and the term "second component" itself does not imply the existence of a "first component".

[0065] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0066] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0067] Unless otherwise stated, numerical ranges herein include not only the entire range between its two endpoints but also the several sub-ranges contained therein.

[0068] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0069] The present invention provides a cooking appliance. The dual-boiler configuration of the cooking appliance allows the user to perform multiple cooking operations simultaneously, improving cooking efficiency and shortening cooking time. The cooking appliance can function as an electric rice cooker and / or an electric pressure cooker to meet diverse cooking needs. In addition to cooking rice, it can also be used for cooking porridge, soup, steaming vegetables, stewing meat, and other various other functions.

[0070] The following will be combined Figures 1 to 5 The cooking appliance according to the present invention is described in detail.

[0071] like Figure 1-Figure 2As shown, the cooking appliance primarily comprises a pot body 100 and a lid 200, which is arranged to open and close above the pot body 100. The pot body 100 has two cylindrical pot storage compartments. The pot is fixedly mounted in the pot storage compartments, or it can be freely inserted and removed from the pot storage compartments for easy cleaning. The pot is typically made of metal and has a circular opening on its top surface for holding ingredients to be heated, such as rice or soup. The pot body 100 also includes a pot heating device and a control device. The pot heating device can be located at the bottom of the pot to heat the food inside, and the user can control the cooking operation of the cooking appliance through the control device. Optionally, the pot heating device can be configured as two independent heater components, one for each pot. The two heaters can operate independently or simultaneously, allowing the double pot cooking appliance to perform two or the same cooking functions.

[0072] The pot body 100 may include a housing 110 and a base 120 located at the lower side of the housing 110. The lower end of the housing 110 may be connected to the base 120 by any suitable means such as snap connection, plug connection, or fastening connection with fasteners such as screws.

[0073] Optionally, a middle plate 400 is provided at the upper end of the pot body 100. Specifically, the middle plate 400 is connected to the upper end of the outer shell 110. The upper end of the outer shell 110 can be connected to the middle plate 400 by any suitable means, such as snap-fitting, plug-in connection, or fastening with fasteners such as screws. Optionally, the middle plate 400 and the base 120 can be connected. For example, the middle plate 400 can be provided with a downwardly extending support column, and the base 120 can be provided with an upwardly extending hollow screw column. The screw can be inserted from the underside of the screw column and partially exit from the top of the screw column to be tightened to the support column.

[0074] The lid 200 has a shape substantially corresponding to the pot body 100. Accordingly, two lids 200 are provided corresponding to the two inner pots. The lid 200 is mounted on the pot body 100 in an openable and closable manner. Specifically, it is pivotally connected to the pot body 100 via a pivot shaft and can freely pivot about a pivot axis located along which the pivot shaft lies between a closed position and an open position relative to the pot body 100, facilitating closing and opening of the pot body 100. When the lid 200 is closed on the pot body 100, it covers the inner pot body and defines a cooking space 101 between the lid and the inner pot body. Optionally, the two lids 200 can be opened and closed independently, or they can be integrated and opened and closed simultaneously. The lid 200 also typically includes a pot mouth sealing ring 210, which can be made of, for example, a rubber material. It is positioned between the lid 200 and the inner pot body to seal the cooking space 101 when the lid 200 is closed. It can be understood that when the two covers 200 are combined with the two pot cores, two independent and relatively sealed cooking spaces 101 are formed.

[0075] It should be noted that directional terms used herein to describe various components and parts of the pot body 100, such as "up," "down," "above," "below," "upward," "downward," "upward," and "downward," are relative to the pot body 100 when it is horizontally placed and upright. Unless otherwise specified, in the directional terms "inward," "outward," "inwardly," "outwardly," "inside," and "outside," "inside," and "outside," "inside" refers to a direction closer to the center of the pot body 100, and "outside" refers to a direction further away from the center of the pot body 100.

[0076] like Figure 2-Figure 3 As shown, the pot inner body includes a first pot inner body 310 and a second pot inner body 320. The heat-insulating cover 500 includes a first heat-insulating cover 510 and a second heat-insulating cover 520. The pot inner body corresponds to the heat-insulating cover 500. The heat-insulating cover 500 is arranged in the pot body 100 and is located outside the pot inner body.

[0077] like Figure 2-Figure 4 As shown, a temperature measuring device is provided in the cover 200 and / or the pot body 100 .

[0078] During the cooking process, when the pot heating device in one pot is operating or the ingredients are at a high temperature, the cooking appliance provided by the present invention releases heat to the surrounding environment through heat radiation, heat conduction, and heat convection. Some of this heat may be transferred to the other pot, thereby affecting the temperature of the other pot. The temperature measuring device is used to measure the internal temperature of the pot, so this heat transfer will inevitably affect the temperature measured by the temperature measuring device. This influence may cause the temperature measured by the temperature measuring device to be inaccurate, thereby affecting the judgment and control of the cooking effect.

[0079] Heat within cooking utensils is primarily transferred through three conduction methods: thermal radiation, thermal conduction, and thermal convection. These three conduction methods ultimately conduct heat through the thermal cover 500 to the temperature measuring device for temperature measurement. Therefore, without changing the reflectivity of the original thermal cover 500 surface or the thermal conductivity of the material, maintaining an appropriate distance is the best solution for minimizing the temperature interaction between the two cooking utensils. In this solution, the minimum distance between the thermal covers 500 is greater than or equal to 40 mm. Specifically, the minimum distance between the first thermal cover 510 and the second thermal cover 520 is greater than or equal to 40 mm.

[0080] Optionally, the first pot 310 provided by the present invention is suitable for pressure cooking, and the second pot 320 is suitable for normal pressure cooking. The first pot 310 is located in the pressure cooker, and the second pot 320 is located in the rice cooker.

[0081] Optionally, a temperature measuring device is provided on the lid 200 of the rice cooker. Specifically, the temperature measuring device can be used to monitor the temperature during the heating phase. The amount of rice in the rice cooker is generally determined by the rate of temperature rise in the inner pot space during the heating phase. The temperature range for this determination is generally 40-100°C, with a 5°C margin. Taking all factors into consideration, an impact of 35°C or more on the temperature measuring device on the top of the rice cooker will disrupt the determination of the rice amount in the pot, thereby affecting the boiling and heat-keeping times.

[0082] Optionally, a temperature measuring device is installed at the bottom of the pressure cooker. This device can be used to monitor the water absorption temperature. The water absorption temperature is generally around 40-50°C, with a 5°C margin. Taking all factors into consideration, an impact of 35°C or more on the temperature of the temperature measuring device at the bottom of the pressure cooker will disrupt the determination of the water absorption temperature for the rice cooking function.

[0083] Optionally, a temperature measuring device is installed at the bottom of the rice cooker. Specifically, the temperature measuring device can be used to monitor the water absorption temperature. The water absorption temperature is generally around 40-50°C. Considering the need for a certain reaction time after the warning and the influence of the external environment, a margin of 5°C is generally allowed. Taking all factors into consideration, an impact of 35°C or more on the temperature of the temperature measuring device at the bottom of the rice cooker will disrupt the determination of the water absorption temperature of the rice cooking function.

[0084] Optionally, a temperature measuring device is installed on the lid 200 of the pressure cooker. Specifically, the temperature measuring device can be used to monitor the temperature during the heating phase. The amount of rice in the pot is generally determined by the rate of temperature rise in the pot chamber during the heating phase. The temperature range for this determination is generally 40-100°C, with a 5°C margin. Taking all factors into consideration, an increase of more than 35°C in the temperature of the temperature measuring device on the top of the pressure cooker will disrupt the determination of the rice amount in the pot, thereby affecting the boiling time and the keep-warm time.

[0085] The following is a specific experimental example to verify the effect of the insulation cover spacing on the temperature measurement when the rice cooker and pressure cooker are working simultaneously.

[0086] The experimental conditions are as follows:

[0087] The ambient temperature is 25℃.

[0088] The distance between the first heat-insulating cover 510 and the second heat-insulating cover 520 is in the range of 30-50 mm.

[0089] The experiment was conducted at 25°C, with the two insulation covers spaced at different distances. The amount of food, the work procedure, and the timing of temperature measurements were strictly controlled to eliminate the possibility of other variables interfering with the results.

[0090] One of the rice cooker and pressure cooker was operated independently in various functions. The temperature of the other was measured at the 20th minute. Each temperature value was measured multiple times in each function, and the highest value was taken. The experimental results are shown in Table 1.

[0091] Table 1

[0092]

[0093] If the temperature of the other non-operating rice cooker or pressure cooker is less than a preset value (e.g., 35°C) when one of the rice cooker and pressure cooker is operating independently, this indicates that the current spacing does not significantly affect temperature detection. Specifically, when the pressure cooker is in various functions, the maximum temperature of the temperature measuring device at the bottom of the rice cooker and the maximum temperature of the temperature measuring device at the top of the rice cooker should both be below 35°C. When the rice cooker is in various functions, the maximum temperature at the temperature probe at the bottom of the rice cooker and the maximum temperature at the temperature probe at the top of the rice cooker should both be below 35°C.

[0094] Based on the above, when the rice cooker and the pressure cooker work at the same time, the normal operation of the rice cooker and the pressure cooker can be guaranteed.

[0095] As can be seen from Table 1, when the distance between the first heat-insulating cover 510 and the second heat-insulating cover 520 is 40 mm, the temperature conduction between the rice cooker and the pressure cooker will not affect the operation of each other. Further increasing the distance between the first heat-insulating cover 510 and the second heat-insulating cover 520 can further reduce the temperature, but it will increase the size of the product and the amount of material used. The appropriate distance can be adjusted according to the actual situation of the cooking appliance.

[0096] An embodiment of the temperature measuring device is described below.

[0097] like Figure 5 As shown, in some embodiments of the present invention, the cover 200 is provided with a first mounting hole 201. The temperature measuring device includes a first temperature measuring probe 610, which extends through the first mounting hole 201. The provision of the mounting hole on the cover 200 allows the first temperature measuring device to be installed more compactly on the cover 200, without occupying excessive space within the cooking appliance.

[0098] Optionally, the first temperature measuring probe 610 extends into the cooking space 101. The first temperature measuring probe 610 directly passes through the first mounting hole 201 and extends into the cooking space 101, which can more directly and accurately measure the actual temperature during the cooking process, reduce loss and interference during heat transfer, and improve the accuracy and reliability of temperature measurement.

[0099] Based on the above embodiment, the first temperature measuring probe 610 can be provided on the two covers 200 to monitor the temperature inside the pressure cooker and the rice cooker respectively.

[0100] In some embodiments of the present invention, the heat-insulating cover 500 is provided with a second mounting hole 501. A temperature measuring device includes a second temperature measuring probe 620, which extends through the second mounting hole 501. The second temperature measuring probe 620 is mounted to the pot body 100 and passes through the second mounting hole 501 of the heat-insulating cover 500. The provision of the second mounting hole 501 allows the second temperature measuring probe 620 to be more compactly mounted on the pot body 100 and the heat-insulating cover 500, thereby optimizing the overall structure.

[0101] Optionally, the second temperature probe 620 abuts the bottom of the inner pot. By directly abutting the second temperature probe 620 against the bottom of the inner pot, it can ensure that the second temperature probe 620 can directly and accurately measure the temperature at the bottom of the inner pot. This direct temperature measurement method reduces heat loss and interference during heat transfer, improving temperature measurement accuracy.

[0102] Optionally, the second temperature probe 620 is located in the center of the bottom of the heat shield 500. The bottom of the pot is where heat is most concentrated and is most sensitive to temperature changes during cooking. Placing the second temperature probe 620 in this location allows for real-time monitoring of temperature changes during cooking, providing accurate data support for cooking control.

[0103] Optionally, the second temperature measuring probe 620 is configured as a temperature sensing cup that can move up and down relative to the heat-insulating cover 500. Optionally, a spring is provided below the temperature sensing cup to bias the cup toward the bottom of the pot, ensuring close contact between the temperature sensing cup and the bottom of the pot, thereby ensuring that the cup does not shift or loosen during temperature measurement. The provision of the temperature sensing cup can also provide some protection for internal components.

[0104] Optionally, the second temperature probe 620 is shaped to match the bottom of the inner pot. This ensures close contact between the probe and the inner pot, reducing thermal resistance and interference from heat transfer during temperature measurement, thereby improving temperature measurement accuracy. The matching shape also serves as a positioning aid during installation.

[0105] Based on the above embodiment, the second temperature measuring probe 620 can be provided on the two cooker bodies 100 to monitor the temperature inside the pressure cooker and the rice cooker respectively.

[0106] The following describes a specific embodiment of the connection between the heat-insulating cover 500 and the middle plate 400.

[0107] like Figure 3As shown, the middle plate 400 has a first opening 401, a first mounting portion 410 extending circumferentially around the first opening 401, a second opening 402, and a second mounting portion 420 extending circumferentially around the second opening 402. Thus, the middle plate 400 forms a structure suitable for mounting two heat-insulating covers 500. The first heat-insulating cover 510 and the second heat-insulating cover 520 can share the same middle plate 400, which not only improves the overall structural compactness of the cooking appliance but also optimizes manufacturing costs and user experience.

[0108] The first heat-insulating cover 510 is located in the first opening 401 of the middle plate 400. That is, the first heat-insulating cover 510 is mounted to the pot body 100 via the first opening 401. The top edge of the first heat-insulating cover 510 extends radially outward to form a first edge 511, and at least a portion of the first edge 511 is located above the first mounting portion 410.

[0109] The second heat-insulating cover 520 is located in the second opening 402 of the middle plate 400 . That is, the second heat-insulating cover 520 is mounted to the pot body 100 via the second opening 402 . The top edge of the second heat-insulating cover 520 extends radially outward to form a second edge 521 , which is connected to the second mounting portion 420 .

[0110] As can be seen above, the first heat-insulating cover 510 is used to mount the first inner pot 310. The second heat-insulating cover 520 is used to mount the second inner pot 320. Thus, the inner pot storage portion of the pot body 100 is formed within the heat-insulating cover 500, allowing the inner pot to be freely placed in and removed from the inner pot storage portion. In other embodiments, the inner pot can be fixed within the inner pot storage portion.

[0111] As can be seen from the above, the heat preservation cover 500 is connected to the middle plate 400. The middle plate 400 provides direct support for the heat preservation cover 500.

[0112] To support pressure cooking, the first heat-insulating cover 510 typically needs to cooperate with the hardware of the lid 200 to withstand internal pressure. In the present invention, the first heat-insulating cover 510 is positioned above the middle plate 400. Specifically, the edge of the first heat-insulating cover 510 is positioned above the first mounting portion 410. This provides sufficient support for the first heat-insulating cover 510 while ensuring the connection strength of the first heat-insulating cover 510. This is crucial for withstanding the internal pressure generated during pressure cooking, ensuring the safety and reliability of the pressure cooking process.

[0113] During normal pressure cooking, the second heat-insulating cover 520 does not need to be in contact with the second inner pot 320. Furthermore, the pressure during normal pressure cooking is generally lower than that during pressure cooking (specifically, high-pressure cooking). In the present invention, to save costs, the second heat-insulating cover 520 can be positioned below the surface. Specifically, the second mounting portion 420 has a mounting groove 421, with at least a portion of the second edge 521 located within the mounting groove 421. The force bearing point of the second heat-insulating cover 520 is located within the mounting groove 421, i.e., at the lower portion of the upper surface of the middle plate 400.

[0114] Thus, by coordinating the first mounting portion 410 with the first heat-insulating cover 510, the edge of the first heat-insulating cover 510 is positioned above the first mounting portion 410. Leveraging the support provided by the middle plate 400, the first heat-insulating cover 510 can safely withstand the internal high pressure generated during cooking, ensuring the safety and reliability of the cooking process. The second mounting portion 420, through the provision of the mounting groove 421, allows a portion of the edge of the second heat-insulating cover 520 to be directly embedded within the mounting groove 421, simplifying the installation process and reducing the need for additional connectors and fixings, further reducing costs. Furthermore, the second edge 521 can be positioned at a lower height, saving material costs for the second heat-insulating cover 520.

[0115] In some embodiments, the upper end of the mounting groove 421 is not closed, that is, the mounting groove 421 has a bottom wall and side walls, and the second edge 521 is overlapped to the bottom wall. In other embodiments, the upper end of the mounting groove 421 is closed, that is, the mounting groove 421 has a top wall, a bottom wall and side walls, and the second edge 521 can be screwed in from the side of the mounting groove 421, thereby overlapping to the bottom wall of the mounting groove 421. The height and shape of the mounting groove 421 match the second edge 521, so that the second edge 521 can be stably installed in the mounting groove 421. The structure of the double-layer groove wall provides stable support and positioning for the second edge 521, preventing it from shaking or falling off during the cooking process. When installing the second thermal insulation cover 520, the user only needs to align the second edge 521 and snap it into the mounting groove 421 to complete the installation.
