Description

Technical Field

[0001] The present invention relates to the field of manufacturing and processing of electrical appliances, and in particular to a multifunctional cooking device. Background Art

[0002] Common cooking methods for consumers include stir-frying, stewing, frying, grilling, and deep-frying. Home kitchens are typically equipped with gas stoves and woks, making stir-frying convenient. However, stir-frying often requires frequent stirring of food ingredients and the addition of seasonings at the right time. Therefore, there is currently little demand for kitchen appliances for stir-frying.

[0003] For stewing, frying, grilling, and deep-frying, there are products on the market such as rice cookers, air fryers, electric ovens, electric hot pots, and electric stew pots. However, these products often have relatively limited functions and fail to meet consumer demand for a variety of food cooking methods. For example, a stir-fry machine has a stirring mechanism for stir-frying food, but it is difficult to fry or boil food. Rice cookers and electric stew pots can only steam food or make soup, but cannot stir food. Their low heating temperature makes it difficult to prepare foods that require higher temperatures. Air fryers use air as a heating medium, which can achieve deep-frying, but it is difficult to stir-fry or steam food.

[0004] With the continuous improvement of living standards, consumers have an increasing demand for diversified food cooking methods. In addition, the kitchen operating space is limited, and single-function kitchen appliances have the problems of high purchase cost, occupying a large amount of kitchen space and low utilization rate of individual products.

[0005] Multi-function cooking devices currently available on the market offer limited cooking options and lack tailored designs for different cooking methods. This makes it difficult for users to thoroughly clean the devices after cooking. This is especially true after frying, grilling, or deep-frying. The fumes and splattered oil not only contaminate the food container but can also spread beyond the container, making cleaning more difficult. Summary of the Invention

[0070] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and is in no way intended to limit the present invention, its application, or use. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the present invention thorough and complete and to fully convey the scope of the present invention to those skilled in the art. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, the composition of materials, numerical expressions, and numerical values ​​set forth in these embodiments should be interpreted as being merely exemplary and not as limiting.

[0071] according to Figure 1 As shown, in one aspect of the present invention, a multifunctional cooking device is provided, comprising a housing assembly 1 and an inner pot assembly 2 detachably disposed within the housing assembly 1. The present invention utilizes a detachable connection between the housing assembly 1 and the inner pot assembly 2, allowing the user to conveniently remove and thoroughly clean the inner pot assembly 2, which has been contaminated by oil and contact with food, after use of the cooking device, thereby effectively improving the hygiene of the cooking device and enhancing user convenience.

[0072] Specifically, if Figure 3As shown, the housing assembly 1 includes a housing 11, a heat-insulating liner 12, a motor 13, and a lower connector 14. The heat-insulating liner 12 is disposed inside the housing 11, and the motor 13 is disposed at the bottom of the housing 11, located between the housing 11 and the heat-insulating liner 12, with the motor shaft 131 extending upward from the bottom of the heat-insulating liner 12, and the lower connector 14 is connected to the motor shaft 131 extending above the heat-insulating liner 12.

[0073] like Figure 2 As shown, the inner pot assembly 2 includes an inner pot 21, a heating pipe 22, a forward fan blade 23, and an upper connector 25. The heating pipe 22 is disposed within the inner pot 21. The forward fan blade 23 is rotatably disposed about a rotation axis 24 between the heating pipe 22 and the bottom surface of the inner pot 21. The rotation axis 24 extends downward from the bottom of the inner pot 21. The upper connector 25 is connected to the rotation axis 24 extending below the inner pot 21 and is detachably connected to the lower connector 14. When the upper connector 25 and the lower connector 14 are connected, torque can be transmitted between the motor 13 and the forward fan blade 23.

[0074] The above division of the outer shell assembly 1 and inner pot assembly 2 indicates that the inner pot assembly 2, with its inner pot 21 and heating tube 22, can utilize the heat from the heating tube 22 to perform cooking tasks such as frying and steaming. The forward fan blades 23, in conjunction with the heating tube 22, further enhance the functionality of the inner pot assembly 2, enabling it to perform air frying in conjunction with the frying basket with a perforation. In contrast to the inner pot assembly 2, the outer shell assembly 1 does not come into close contact with the food, but instead provides auxiliary support. Its motor 13 drives the forward fan blades 23, while its insulated inner pot 12 isolates the heat from the inner pot 21, preventing burns.

[0075] Generally speaking, the inner pot assembly 2, which is in close contact with the food, is easily contaminated by oil smoke and splashing oil droplets during the cooking process. Therefore, there is a great demand for cleaning the inner pot assembly 2. In traditional multi-functional cooking devices, the inner pot assembly 2 and the outer shell assembly 1 are inseparable because they involve the transmission of the motor 13. This means that the user can only clean the inner pot assembly 2 and the outer shell assembly 1 synchronously without disassembling them, resulting in incomplete cleaning of the inner pot assembly 2.

[0076] To address this issue, the present invention solves the technical problem of the inner pot assembly 2 and the outer shell assembly 1 being non-detachable by means of an upper connector 25 and a lower connector 14 that can be disassembled from each other, and enables the upper connector 25 and the lower connector 14 to transmit torque between the motor 13 and the forward fan blade 23 when they are connected to each other, thereby further ensuring the normal working requirements of the multi-functional cooking container.

[0077] As the inner pot assembly 2 and the outer shell assembly 1 are disassembled from each other, the power supply to the heating tube 22 also needs to be designed specifically: preferably, the outer shell assembly 1 also includes a lower coupler 15, which is fixedly arranged on the heat-insulating tank 12 and electrically connected to an external power supply; and the inner pot assembly 2 also includes an upper coupler 26, which is electrically provided at the end of the heating tube 22, passes through the inner tank 21 and is detachably connected to the lower coupler 15, and when the lower coupler 15 and the upper coupler 26 are connected to each other, the external power supply can supply power to the heating tube 22.

[0078] Therefore, the mutual disassembly and connection between the upper coupler 26 and the lower coupler 15 are linked with the disassembly and installation of the outer shell assembly 1 and the inner pot assembly 2, thereby realizing the plug-in power supply to the heating tube 22 and meeting the electrical connection requirements between the heating tube 22 and the external power supply.

[0079] like Figure 6 、 10 As shown, the multifunctional cooking device preferably further includes a frying pan 3 and a frying pan switch 4. The frying pan 3 is removably disposed within the insulating container 12 for performing the frying and cooking functions of the multifunctional cooking device. The frying pan switch 4 is disposed on the bottom surface of the inner container 21, extending above the insulating container 12. When the frying pan 3 is disposed within the insulating container 12, the frying pan 3 is pressed downward, thereby energizing a working circuit corresponding to the frying pan 3 in the multifunctional cooking device.

[0080] By providing a frying pan switch 4 and a frying pan 3 that responds to pressing the frying pan switch 4, the present invention enables the multifunctional cooking device to automatically identify the frying pan 3. Thus, when the user replaces the frying pan 3, the corresponding operating circuit is automatically activated, facilitating user operation. The frying pan switch 4 can be positioned at a point that distinguishes the frying pan 3 from other cooking containers, ensuring that only the frying pan 3 can be effectively activated by pressing the frying pan switch 4.

[0081] Considering that users are usually accustomed to opening the cover when frying to turn the food over and observe the cooked state of the food at any time, in order to improve the safety of the multi-functional cooking device when frying, it is preferred that Figure 6 As shown, the multifunctional cooking device further includes a temperature sensing head 5, which is arranged on the bottom surface of the inner pot 21 and extends above the heat-insulating pot 12. The temperature sensing head 5 is configured to measure the internal temperature of the heat-insulating pot 12 when the frying pan switch 4 contacts the frying pan 3, and to activate power-off protection when the measured temperature exceeds a temperature threshold.

[0082] The temperature threshold corresponding to the temperature sensing head 5 can be set to 200° C., which is lower than the boiling point of general cooking oil, to prevent the risk of scalding to the user due to splashing oil droplets during frying.

[0083] Preferably, the multifunctional cooking device further comprises a slow cooker and a fry basket. The slow cooker is removably disposed within the heat-insulating container 12 for performing the stewing cooking function of the multifunctional cooking device, and similarly, the fry basket is removably disposed within the heat-insulating container 12 for performing the air-frying cooking function of the multifunctional cooking device.

[0084] To enable the multi-function cooking device to automatically enter the corresponding cooking state according to the cooking container, the housing assembly 1 further includes a pressure plate 113, a lid, a slow cooker switch 114, and an air fryer switch 115. The pressure plate 113 is circumferentially pressed against the edge of the insulated container 12; the lid is hingedly connected to the housing 11 and can be opened or closed to cover the opening of the insulated container 12, pressing against the upper surface of the pressure plate 113; the slow cooker switch 114 is disposed above the edge of the insulated container 12, exposed on the inner side of the pressure plate 113, and configured to conduct a corresponding operating circuit of the slow cooker in the multi-function cooking device when the lid is pressed against the pressure plate 113 and pressed downward by the slow cooker; and the air fryer switch 115 is disposed above the edge of the insulated container 12, exposed on the inner side of the pressure plate 113, and configured to conduct a corresponding operating circuit of the air fryer in the multi-function cooking device when the lid is pressed against the pressure plate 113 and pressed downward by the fryer basket.

[0085] Unlike frying, users typically close the lid during steaming and air frying. This is because they don't need to frequently stir the food, and because keeping the lid closed effectively saves energy during cooking. Leveraging this characteristic, the present invention combines the action of the slow cooker switch 114 and the air fryer switch 115 being pressed by the corresponding cooking container with the action of the lid pressing against the pressure plate 113. This avoids the potential user inconvenience of automatically initiating the corresponding cooking step upon placing the cooking container. Instead, the corresponding operating circuit is activated only after the user places the cooking container and closes the lid, making the workflow of the multi-functional cooking device more consistent with user habits.

[0086] In order to make the transmission between the lower connector 14 and the upper connector 25 more efficient and reduce the operating noise, Figure 9 As shown, preferably, the top surface of the lower connector 14 is provided with a first circular groove 141, and the shell assembly 1 also includes a shock absorber 16, which is made of a flexible material and can be embeddedly installed inside the first circular groove 141 of the lower connector 14, and a second circular groove 161 is provided on its top surface, and the second circular groove 161 can be embeddedly installed with the upper connector 25; wherein, the lower connector 14 is provided with a plurality of tooth grooves 142 along the outer periphery of the first circular groove 141, the shock absorber 16 is provided with a plurality of protrusions 162 corresponding to the plurality of tooth grooves 142, the upper connector 25 is provided with a plurality of outward-extending teeth 251, and the shock absorber 16 is provided with a plurality of inward-extending teeth 163 corresponding to the plurality of outward-extending teeth 251.

[0087] Due to the first circular groove 141 on the top surface of the lower connector 14 and the second circular groove 161 on the top surface of the shock absorber 16, the lower connector 14, the shock absorber 16 and the upper connector 25 are nested with each other in the installed state, which can effectively save the size of the multi-functional cooking device along the motor shaft 131, making the structure more compact, and the shock absorber 16 made of flexible material can effectively absorb the vibration of the motor 13 during the transmission process, greatly reducing the working noise.

[0088] On this basis, the tooth groove 142 cooperates with the protrusion 162 to improve the torque transmission capacity between the lower connector 14 and the shock absorber 16, and the outward-extending teeth 251 cooperate with the inward-extending teeth 163 to improve the torque transmission capacity between the shock absorber 16 and the upper connector 25. In summary, the ability of the lower connector 14 to transmit torque to the upper connector 25 will also be improved.

[0089] In order to dissipate the heat in the heat-insulating tank 12 in time and ensure that the operating temperature of the motor 13 is not too high, Figure 7 As shown, preferably, the housing assembly 1 further includes a heat dissipation fan blade 17, a fan cover 18, and an air outlet net 19. The heat dissipation fan blade 17 is arranged between the motor 13 and the heat-insulating bladder 12, is coaxially arranged with the forward fan blade 23, and is driven by the motor 13; the fan cover 18 is arranged at the bottom of the heat-insulating bladder 12, separated between the motor 13 and the heat dissipation fan blade 17, and forms a cooling cavity between the fan cover 18 and the heat-insulating bladder 12; and the air outlet net 19 is fixedly arranged on one side of the bottom of the housing 11, including a first air outlet 191 and a second air outlet 192. The first air outlet 191 is in communication with the interior of the fan cover 18, forming an exhaust channel from the cooling cavity to the outside, and the second air outlet 192 is in communication with the interior of the heat-insulating bladder 12, forming an exhaust channel from the heating cavity inside the heat-insulating bladder 12 to the outside.

[0090] The cooling cavity formed between the air hood 18 and the thermal insulation tube 12 can effectively isolate the heat from being transferred from the inside of the thermal insulation tube 12 to the motor 13. In addition, the present invention arranges heat dissipation fan blades 17 in the cooling cavity, which can further utilize the heat dissipation fan blades 17 to drive the air to be discharged from the first air outlet 191 of the air outlet network 19 to the external environment, thereby ensuring that the temperature in the cooling cavity is not too high, thereby ensuring that the operating temperature of the motor 13 meets the requirements.

[0091] Correspondingly, the temperature in the insulation cavity should not be too high to avoid damaging the structure of the inner pot assembly 2. Therefore, the present invention uses the forward fan blades 23 and the second air outlet 192 of the air outlet net 19 to form an exhaust system so that the high-temperature air in the insulation cavity can be discharged in time.

[0092] Based on the position of the air outlet net 19, in order to prevent the user from being scalded, Figure 7As shown, the housing assembly 1 preferably further includes a housing decorative sheet 111 and a control panel 112. The housing decorative sheet 111 is spaced apart from the outside of the housing 11, forming a heat-insulating cavity with the housing 11 to prevent burns to the user from direct contact with the housing 11. The control panel 112 is disposed outside the housing decorative sheet 111 and opposite the air outlet mesh 19. As a result, the control panel 112 is sufficiently spaced apart from the air outlet mesh 19 and positioned in opposite directions to prevent the user from touching the air outlet mesh 19 or being burned by the high-temperature gas discharged from the air outlet mesh 19 while operating the control panel 112.

[0093] like Figure 5 、 8 As shown, to collect any oil that may appear within the insulating liner 12, the housing assembly 1 further includes an oil column 110. The lower end of the oil column 110 is disposed on the upper portion of the bottom surface of the housing 11, and the upper end extends beyond the inner liner 21. The oil column 110 can then discharge the collected oil from the bottom of the housing 11, thereby forming a circular collection system for the leaked oil.

[0094] Preferably, the air hood, the heat-insulating container and the inner container are provided with a plurality of groups of mounting holes extending from bottom to top along the height direction, and each group of mounting holes is used to fix the oil leakage column, the lower coupler, the shock absorber, the lower connector, the frying pan switch and the temperature sensor head respectively;

[0095] Wherein, a water retaining edge is provided on the periphery of the mounting hole so that the opening of the mounting hole is higher than the plane where the mounting hole is opened by the wind cover, the heat-insulating liner and the inner liner.

[0096] On the basis of this structure, in order to prevent the oil from invading the frying pan switch 4, the temperature sensor head 5, the lower coupler 15, the shock absorber 16, the lower connector 14 and / or the mounting hole 6 of the oil leakage column 110 from the surfaces of the air hood 18, the heat-insulating pot 12 and the inner pot 21 during the process of collecting the leaked oil, preferably, a water retaining edge is provided on the outer periphery of the mounting hole so that the opening of the mounting hole is higher than the plane in which the mounting hole is opened by the air hood, the heat-insulating pot and the inner pot.

[0097] The following is combined with Figure 1-10 The present invention will be further described:

[0098] A removable and washable multifunctional cooking device comprises an inner pot assembly 2 and an outer shell assembly 1. The inner pot assembly 2 is equipped with a heating pipe 22, an upper coupler 26, a fan cover, forward fan blades 23, a bracket, an inner pot 21, a rotating shaft 24, a gasket, a bearing, an upper connector 25, and a locking nut. The outer shell assembly 1 is equipped with a pressure plate 113, a heat-insulating pot 12, a fan cover 18, a lower coupler 15, a shock absorber 16, a lower connector 14, heat dissipation fan blades 17, a motor 13, a base, a wire clamp, an air outlet screen 19, an outer shell decorative panel 111, a housing 11, and a control panel 112.

[0099] The inner pot 21 of the inner pot assembly 2 is provided with a frying pan switch hole, a temperature sensor hole, an oil leak hole, and a mounting hole 6 for the lower coupler and the lower connector. The insulating pot 12 of the outer shell assembly 1 is provided with a frying pan switch hole, a temperature sensor hole, an oil leak hole, a mounting hole 6 for the lower coupler, a mounting hole 6 for the shock absorber, and the mounting hole 6 for the lower connector. The fan cover 18 of the outer shell assembly 1 is provided with a frying pan switch hole, a temperature sensor hole, an oil leak hole, a mounting hole 6 for the lower coupler, a mounting hole 6 for the shock absorber, and the mounting hole 6 for the lower connector.

[0100] The assembly relationship between the inner pot assembly 2 and the outer shell assembly 1 is:

[0101] After the upper end of the rotating shaft 24 in the inner pot assembly 2 passes through two bearings and then through the rotating shaft 24 hole at the bottom center of the inner pot 21, a gasket is movably installed on the upper end of the rotating shaft 24. The shaft hole of the forward fan blade 23 is then fixedly installed on the rotating shaft 24 that is exposed at the bottom center of the inner pot 21.

The wire clamp in the shell assembly 1 is fixedly mounted on the bottom edge of the base and is used to fix the power cord.

[0108] Working principle of the present invention:

[0109] After the user has used it for a period of time, the heating tube 22, the upper coupler 26, the fan cover, the forward fan blade 23 and the inner pot 21 in the inner pot assembly 2 will inevitably be contaminated by the oil after frying. In order to facilitate cleaning, the inner pot assembly 2 and the outer shell assembly 1 are movably connected to facilitate disassembly and installation.

[0110] Since the inner pot 21 in the inner pot assembly 2 is movably connected to the lower connector 14 and the shock absorber 16 in the outer shell assembly 1 through the upper connector 25, when the user lifts the cooled inner pot assembly 2, the upper connector 25 below the inner pot 21 is separated from the lower connector 14 in the outer shell assembly 1, and the upper coupler 26 in the inner pot 21 is separated from the lower coupler 15 in the outer shell assembly 1, so that the user can disassemble the various components in the inner pot assembly 2 one by one again for cleaning, or install the various components in the inner pot assembly 2 one by one and use them again.

[0111] When the frying pan 3 is placed, the bottom surface of the frying pan 3 contacts the frying pan switch 4 and the temperature sensor head 5 in the housing assembly 1. The frying pan switch 4 is affected by the gravity of the frying pan 3, so that the control circuit in the control panel assembly 112 receives the information that the frying pan switch 4 is turned on, and controls the control circuit in the control panel assembly 112 to activate the corresponding frying and grilling functions, such as menu selection, power, time, and temperature adjustment.

[0112] When the temperature sensed by the temperature sensor head 5 in the housing component 1 exceeds the temperature threshold set by the user, such as 200°C, the temperature sensor head 5 transmits this temperature value to the control circuit in the control panel 112 component, and the control circuit is powered off for protection.

[0113] When a slow cooker is placed in the inner pot 21, the bottom of the slow cooker contacts the heating tube 22 in the inner pot assembly 2 for heating; the edge of the slow cooker passes through the slow cooker switch 114 in the pressure plate 113 and contacts the slow cooker switch 114. The slow cooker switch 114 is affected by the gravity of the slow cooker, so that the control circuit in the control panel 112 assembly receives the information that the slow cooker switch 114 is turned on, and starts the corresponding slow cooking function in the control panel 112 assembly, such as menu selection, power, time, and temperature adjustment.

[0114] When the upper cover and the pressure plate 113 are closed, the edge of the upper cover passes through the pressure plate 113 and contacts the air-frying switch 115. The air-frying switch 115 is affected by the gravity of the upper cover, so that the control circuit in the control panel 112 component receives the information that the air-frying switch 115 is turned on, and starts the corresponding air-frying function in the control panel 112 component, such as menu selection, power, time, and temperature adjustment.

[0115] Therefore, the present invention provides a detachable connection between the outer shell assembly 1 and the inner pot assembly 2, so that after using the cooking device, the user can easily remove the inner pot assembly 2 that has been in contact with food and contaminated with oil and clean it thoroughly, thereby effectively improving the hygiene of the cooking device and increasing the convenience of user use.
