Description

Technical Field

[0001] This application belongs to the field of household appliance technology, specifically relating to a cooking appliance. Background Technology

[0002] For cooking appliances such as ovens, steam ovens, or microwave-steam-grill combination machines, their cooking chambers have a large volume, which makes cooking small portions of food slow and wasteful of energy.

[0003] Therefore, improving the speed and energy efficiency of cooking appliances when cooking small portions of food has become an urgent problem to be solved. Summary of the Invention

[0004] This application aims to solve the technical problem that cooking appliances in related solutions are slow and wasteful of energy when cooking small portions of food.

[0005] To address the aforementioned technical problems, embodiments of this application provide a cooking utensil.

[0006] An embodiment of this application provides a cooking appliance, comprising: a housing, wherein a first cooking cavity and a second cooking cavity are disposed within the housing, the second cooking cavity being located outside the first cooking cavity; a heating device for heating food within the first cooking cavity and / or the second cooking cavity; wherein the volume of the first cooking cavity is greater than the volume of the second cooking cavity; a first opening disposed on the housing and communicating with the second cooking cavity; and a cover movably installed at the first opening for opening and closing the first opening.

[0007] The cooking appliance provided according to the embodiments of this application includes a housing, a heating device, a first opening, and a lid. The housing contains a larger first cooking cavity and a smaller second cooking cavity. The heating device is used to heat the food in the first and / or second cooking cavities. The lid is used to open and close the second cooking cavity. The first cooking cavity, as the main cooking area of ​​the appliance, has a large volume, providing the cooking capacity needed for most everyday scenarios. The second cooking cavity, with its smaller volume, is mainly used for cooking small quantities of food quickly, meeting the needs of cooking scenarios such as breakfast. With this structure, the larger volume of the first cooking cavity allows for faster heating and higher energy efficiency when cooking the same amount of food using both the first and second cooking cavities. This solves the technical problem of large cooking cavities in cooking appliances resulting in slow cooking speeds and energy waste when cooking small portions of food.

[0008] The first opening on the casing can be used to place food into the second cooking cavity. Of course, when the second cooking cavity can be removed separately, it can also be removed through the first opening for cleaning. The cover is used to close and open the first opening to open and close the second cooking cavity, thus facilitating cooking or taking food out of the second cooking cavity.

[0009] Furthermore, since the second cooking chamber is separately located outside the first cooking chamber, the two cooking chambers are completely independent and isolated from each other. This avoids the problem of flavors mixing between the first and second cooking chambers when cooking simultaneously. Moreover, this arrangement eliminates the need to separate the first cooking chamber, allowing cooking to occur simultaneously through both chambers. This enables simultaneous cooking of large quantities and multiple types of ingredients, while also expanding the overall cooking capacity of the appliance.

[0010] The heating device can be one or more. When there are multiple heating devices, they can be of different types or all of the same type. When the heating device is a steam, microwave, hot air, or other heating structure, multiple pipes can also be provided to input steam, microwave, hot air, etc., into the first cooking cavity and / or the second cooking cavity.

[0011] In any of the above embodiments, optionally, a first inlet is provided on the first cooking cavity, and a second inlet is provided on the second cooking cavity; the heating device can selectively open the first inlet or the second inlet, or simultaneously open the first inlet and the second inlet, when the first inlet is opened, the heating device delivers at least one of steam, microwave and hot air into the first cooking cavity, and when the second inlet is opened, the heating device delivers at least one of steam, microwave and hot air into the second cooking cavity.

[0012] In this embodiment, the heating device is capable of cooking using microwaves, steam, or hot air. A first inlet is provided on the first cooking chamber to allow steam, microwaves, or hot air to enter and heat the food within. A second inlet is provided on the second cooking chamber to allow steam, microwaves, or hot air to enter and heat the food within.

[0013] The heating device includes a microwave heating device and / or a steam heating device. The heating device can perform microwave heating or steam heating. Of course, the heating device can also have both microwave heating and steam heating functions at the same time.

[0014] In any of the above embodiments, optionally, the cooking appliance further includes: a first channel connecting the heating device and a first inlet, wherein a first switch is provided on the first channel for opening or closing the first channel to connect or disconnect the heating device from the first inlet. This allows or blocks the heating device from supplying steam, microwaves, or hot air into the first cooking cavity. The cooking appliance further includes: a second channel connecting the heating device and a second inlet, wherein a second switch is provided on the second channel for opening or closing the second channel to connect or disconnect the heating device from the second inlet. This allows or blocks the heating device from supplying steam, microwaves, or hot air into the second cooking cavity. The cooking appliance further includes: a control device connected to the first switch and the second switch for controlling the operation of the first switch and the second switch.

[0015] In this embodiment, when cooking ingredients, the state of the first switch can be controlled as needed to control the conduction of the first and second channels, thereby controlling the object being heated by the heating device. This allows the heating of the first or second cooking chamber to be activated as needed, enabling the cooking appliance to achieve multiple heating modes.

[0016] The control device can control the operation of the first switch and the second switch according to user instructions during use, thereby realizing the electric control of the first switch and the second switch.

[0017] In any of the above embodiments, optionally, the cooking appliance includes a first heating mode, a second heating mode, and a third heating mode. In the first heating mode, the heating device opens the first inlet; in the second heating mode, the heating device opens the second inlet; and in the third heating mode, the heating device opens both the first and second inlets simultaneously.

[0018] In this embodiment, the cooking appliance has different operating modes, wherein the energy efficiency of the first heating mode is lower than that of the second heating mode. That is, the energy efficiency of cooking through the second cooking chamber is greater than that of cooking through the first cooking chamber. In other words, the second cooking chamber enables more efficient (faster) cooking compared to the first cooking chamber. During use, the user can control the cooking appliance to operate according to different modes as needed.

[0019] For example, when heating a large amount of food, the first heating mode can be selected for regular heating through the first cooking chamber. When heating a smaller amount of food, the second heating mode can be selected for rapid heating of a small quantity. For instance, common breakfast ingredients such as corn, eggs, and sweet potatoes can be cooked through the second cooking chamber, making the appliance suitable for quick breakfast preparation. When heating different types of food, the third heating mode can be selected to heat the food simultaneously through the first and second cooking chambers. Alternatively, when heating a large amount of food, the food can be placed separately in the first and second cooking chambers, and then the third heating mode can be selected for simultaneous heating through both chambers. This structure makes the heating modes of the appliance more flexible, better meeting different user heating needs and improving the user experience.

[0020] In any of the above embodiments, optionally, the cooking appliance further includes: a control panel movably installed at the first opening for controlling the operation of the cooking appliance; the cover is the control panel or the cover is installed on the control panel, the control panel has a first position and a second position relative to the housing, in the first position the control panel covers the first opening, and in the second position the control panel opens the first opening.

[0021] In this embodiment, the control panel is used to control the operation of the cooking appliance, such as controlling the working mode and adjusting cooking parameters. The control panel and the first cooking cavity can be installed vertically (generally with the control panel above the first cooking cavity) or horizontally (generally with the control panel to the right of the first cooking cavity). The second cooking cavity and the control panel are installed on the same side of the first cooking cavity. This can be understood as the second cooking cavity being installed in the control area (non-cooking area) of the cooking appliance. With this arrangement, the second cooking cavity does not occupy the cooking area and does not affect the size of the first cooking cavity, thus ensuring that the volume of the first cooking cavity does not decrease while installing the second cooking cavity.

[0022] Meanwhile, the cover serves as the control panel or is mounted on the control panel. In this embodiment, the control panel is movably mounted at the first opening, allowing it to be opened and closed to open and close the second cooking cavity. Essentially, the cover and control panel are integrated. Opening the second cooking cavity directly through the control panel eliminates the need for a separate cover, allowing for a larger control panel design. This enables a large-screen (or large-panel) control panel design without reducing its overall area.

[0023] When it is necessary to place or remove ingredients into the second cooking cavity, the control panel can be opened and moved to the second position to expose the first opening. After the ingredients have been placed and cooking is required, or when the second cooking cavity is not in use, the control panel can be returned to the closed position to close the second cooking cavity.

[0024] Alternatively, the control panel can be installed on the door of the cooking appliance to avoid obstructing the second cooking chamber.

[0025] Furthermore, the control panel and the second cooking cavity are located above the first cooking cavity in the height direction. Furthermore, the cooking appliance is a built-in cooking appliance.

[0026] In other embodiments, the cover may be separate from the control panel. For example, the cover may be located on one side of the control panel.

[0027] In any of the above embodiments, optionally, a first inlet is provided on the first cooking cavity, and a second inlet is provided on the second cooking cavity. The heating device includes a steam generator and a water tank. The steam generator can selectively open the first inlet or the second inlet, or simultaneously open the first inlet and the second inlet, to deliver steam to the first inlet and / or the second inlet. The water tank is used to supply water to the steam generator. The water tank is detachably installed inside the housing and can enter and exit the housing through the first opening.

[0028] In this embodiment, the heating device is a steam heating device. That is, the heating device is mainly used to generate steam and heat water using steam. Further, the heating device includes a steam generator. The steam generator is used to heat water to generate steam. The heating device may also include a water tank, which supplies water required for steam generation to the steam generator. The installation location and structure of the water tank are not limited.

[0029] In one specific embodiment, the water tank can be installed inside the control panel. When water is not needed, the water tank can be hidden inside the control panel. When water needs to be added, the control panel can be opened to add water. This structure allows for concealed installation of the water tank, ensuring that the water tank does not occupy surface space on the product. This frees up more space for the control panel, facilitating a large-screen (or large panel) design.

[0030] In one specific embodiment, since the water tank and the second cooking cavity are smaller than the first cooking cavity, the water tank and the second cooking cavity can be set on the same side of the first cooking cavity along the height or width direction of the container. This can make the structural layout of the cooking appliance more reasonable and improve the space utilization of the cooking appliance.

[0031] In any of the above embodiments, the heating device may optionally further include: a microwave generating device for delivering microwaves into the first cooking cavity and / or the second cooking cavity.

[0032] In this embodiment, the cooking appliance can perform both steam cooking and microwave cooking. During microwave cooking, the microwave generator can input microwaves into the first cooking cavity through a first inlet and into the second cooking cavity through a second inlet. Alternatively, a separate microwave delivery port can be provided to input microwaves into both the first and second cooking cavities.

[0033] In any of the above embodiments, the heating device may optionally include: a first heat radiation device, installed inside the second cooking cavity, for radiating heat into the second cooking cavity.

[0034] In this embodiment, the second cooking cavity or the food inside it can be heated by the first thermal radiation device, so that the food can be baked and heated by the first thermal radiation device.

[0035] In any of the above embodiments, the heating device may optionally include: a second heat radiation device, installed inside the first cooking cavity, for radiating heat into the first cooking cavity.

[0036] In this embodiment, the first cooking cavity or the food inside it can be heated by the second thermal radiation device, so that the food inside the first cooking cavity can be baked and heated by the second thermal radiation device.

[0037] In any of the above embodiments, optionally, the volume of the second cooking chamber is less than or equal to 20 liters, for example, the volume of the second cooking chamber can be 15 liters or 10 liters.

[0038] In any of the above embodiments, optionally, half the volume of the first cooking cavity is greater than the volume of the second cooking cavity.

[0039] Furthermore, the volume of the first cooking cavity is half the volume of the second cooking cavity, meaning the volume of the first cooking cavity is more than twice the volume of the second cooking cavity. This results in a significant difference in volume between the first and second cooking cavities. When heating is performed through the first and second cooking cavities, the difference in heating speed and energy efficiency becomes more pronounced. This allows for a more significant enhancement of the heating advantage of the second cooking cavity and improves its utilization rate.

[0040] In any of the above embodiments, optionally, the housing includes: an outer shell; a rapid heating cavity detachably installed inside the outer shell, wherein a second cooking cavity is provided inside the rapid heating cavity; the cooking appliance also includes a sensor installed inside the outer shell for sensing whether the rapid heating cavity is installed in place.

[0041] In this embodiment, the housing includes an outer shell, which serves as the product's exterior component and protects and houses other parts of the product. A rapid heating chamber is detachably installed within the outer shell. The rapid heating chamber is used for quick cooking and includes a second cooking chamber for holding food. Simultaneously, a sensor is installed within the outer shell to detect whether the rapid heating chamber is properly installed, ensuring that it can be reinstalled correctly after disassembly and ensuring accurate connection between the rapid heating chamber and the steam inlet within the outer shell. Alternatively, in other solutions, a guide structure can be provided to guide the correct installation of the rapid heating chamber, in which case the sensor may not be necessary.

[0042] Furthermore, sensors can be used to control whether the rapid heating chamber can work, ensuring that cooking can only take place when the rapid heating chamber is installed in place. If the sensor does not detect the rapid heating chamber, it can be locked.

[0043] In any of the above embodiments, optionally, the second cooking cavity is provided with a second inlet, and the outer shell is provided with a plug-in interface. When the rapid heating cavity is installed in the outer shell, the plug-in interface is detachably connected to the second inlet, and the connection between the plug-in interface and the second inlet is sealed. When the heating device is connected to the second inlet, it delivers at least one of steam, microwave and hot air into the rapid heating cavity.

[0044] In this embodiment, the second cooking cavity is movably installed within the housing. For example, the second cooking cavity can be detachably installed on the housing. When the second cooking cavity is correctly installed within the housing, for example, when it is installed inside the outer shell and in a first installation state (i.e., a predetermined correct installation state), the connector and the second inlet are detachably connected, and the connection between them is sealed. With this structure, after the second cooking cavity is installed in the correct position within the housing (i.e., the second cooking cavity is in the first installation state relative to the housing), the connector and the second inlet can be quickly connected to ensure that steam, microwaves, or hot air generated by the heating device can enter the second cooking cavity. When it is necessary to remove the second cooking cavity (in other installation states), the connector and the second inlet can be easily disconnected to ensure that the second cooking cavity can be quickly removed.

[0045] In any of the above embodiments, the cooking appliance may optionally include a carrier member, which is detachably installed in the second cooking cavity for carrying ingredients or an ingredient container.

[0046] In this embodiment, the carrier is installed inside the second cooking cavity to hold food ingredients or food containers. When the second cooking cavity cannot be disassembled, the food ingredients can be removed and placed in by using the carrier. Of course, even when the second cooking cavity itself is detachable, the carrier can still be configured to make the removal and placement of food ingredients more flexible.

[0047] In any of the above embodiments, optionally, the cooking appliance further includes a door mounted on the housing for opening and closing the first cooking chamber. Further, the door is positioned on the housing, bypassing the second cooking chamber, so that the second cooking chamber can be opened or closed independently, unaffected by the door.

[0048] The first cooking cavity can be a built-in, non-removable structure, or it can be a pull-out and openable structure.

[0049] Optionally, in any of the above embodiments, the cooking appliance further includes a vent that communicates with the second cooking chamber. The vent ensures that the second cooking chamber is connected to the outside atmosphere, preventing excessive pressure in the second cooking chamber during cooking.

[0050] Optionally, the housing includes an outer shell and an inner liner, with the inner liner installed inside the outer shell. The inner liner forms a first cooking cavity. A second cooking cavity and a heating device are installed between the outer shell and the inner liner.

[0051] Alternatively, the cooking appliance may be an oven, a steam oven, or a microwave-steam-oven combination appliance.

[0077] The embodiments of this application will now be described in detail. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0078] The cooking appliance according to embodiments of this application will now be described with reference to the accompanying drawings.

[0079] like Figures 1 to 21 As shown, an embodiment of this application provides a cooking appliance, including a housing 1, a heating device 5, a first opening 16, and a lid 4. The housing 1 contains a first cooking cavity 12 and a second cooking cavity 142, with the second cooking cavity 142 located outside the first cooking cavity 12. The heating device 5 is used to heat the food inside the first cooking cavity 12 and / or the second cooking cavity 142. The volume of the first cooking cavity 12 is larger than the volume of the second cooking cavity 142. The first opening 16 is disposed on the housing 1 and communicates with the second cooking cavity 142. The lid 4 is movably installed at the first opening 16 and is used to open and close the first opening 16.

[0080] The cooking appliance according to an embodiment of this application includes a housing 1, a heating device 5, a first opening 16, and a lid 4. The housing 1 contains a larger first cooking cavity 12 and a smaller second cooking cavity 142. The heating device 5 is used to heat the food inside the first cooking cavity 12 and / or the second cooking cavity 142. The lid 4 is used to open and close the second cooking cavity 142. The first cooking cavity 12, as the main cooking area of ​​the cooking appliance, has a large volume, providing the cooking capacity required for most daily scenarios. The second cooking cavity 142 has a smaller volume and is mainly used for cooking small amounts of food, enabling rapid cooking of small quantities of food to meet the needs of cooking scenarios such as breakfast. With this structure, the larger volume of the first cooking cavity 12 allows for faster heating and higher energy efficiency when cooking the same amount of food using both the second and first cooking cavities. This solves the technical problem of large cooking cavity volumes in cooking appliances, resulting in slow cooking speeds and energy waste when cooking small portions of food.

[0081] The first opening 16 on the housing 1 can be used to place food into the second cooking cavity 142. Of course, when the second cooking cavity 142 can be removed separately, it can also be removed through the first opening 16 for cleaning. The cover 4 is used to close and open the first opening 16 to open and close the second cooking cavity 142, which facilitates cooking or taking out food through the second cooking cavity 142.

[0082] Furthermore, since the second cooking cavity 142 is separately and additionally located outside the first cooking cavity 12, the first cooking cavity 12 and the second cooking cavity 142 are completely independent and can be completely isolated from each other. This avoids the problem of flavors mixing between the first cooking cavity 12 and the second cooking cavity 142 when cooking simultaneously. Moreover, this arrangement does not require separating the first cooking cavity 12, allowing cooking to occur simultaneously through the first cooking cavity 12 and the second cooking cavity 142. This enables simultaneous cooking of both the first and second cooking cavities, accommodating both large quantities and multiple types of ingredients while also expanding the overall cooking capacity of the cooking appliance.

[0083] The heating device 5 can be one or more. When there are multiple heating devices 5, they can be set to different types of heating devices 5, or they can all be set to the same type of heating device 5. When the heating device 5 is a heating structure such as steam, microwave, or hot air, multiple pipes can also be set to input steam, microwave, hot air, etc. to the first cooking cavity 12 and / or the second cooking cavity 142.

[0084] In any of the above embodiments, optionally, as Figure 20 As shown, a first inlet 122 is provided on the first cooking cavity 12, and a second inlet 1422 is provided on the second cooking cavity 142. The heating device 5 can selectively open the first inlet 122 or the second inlet 1422, or simultaneously open both the first inlet 122 and the second inlet 1422. When the first inlet 122 is opened, the heating device 5 supplies at least one of steam, microwave and hot air into the first cooking cavity 12. When the second inlet 1422 is opened, the heating device 5 supplies at least one of steam, microwave and hot air into the second cooking cavity 142.

[0085] In this embodiment, the heating device 5 can cook using microwaves, steam, or hot air. A first inlet 122 is provided on the first cooking chamber 12 to allow steam, microwaves, or hot air to enter and heat the food within it. A second inlet 1422 is provided on the second cooking chamber 142 to allow steam, microwaves, or hot air to enter and heat the food within it.

[0086] The heating device 5 includes a microwave heating device and / or a steam heating device. The heating device 5 can perform microwave heating or steam heating. Of course, the heating device 5 can also have both microwave heating and steam heating functions at the same time.

[0087] In any of the above embodiments, optionally, as Figure 20 As shown, the cooking appliance also includes: a first channel 62, connecting the heating device 5 and the first inlet 122. A first switch 622 is provided on the first channel 62 for opening or closing the first channel 62 to connect or disconnect the heating device 5 from the first inlet 122. This allows or blocks the heating device 5 from supplying steam, microwaves, or hot air into the first cooking cavity 12. The cooking appliance also includes: a second channel 64, connecting the heating device 5 and the second inlet 1422. A second switch 642 is provided on the second channel 64 for opening or closing the second channel 64 to connect or disconnect the heating device 5 from the second inlet 1422. This allows or blocks the heating device 5 from supplying steam, microwaves, or hot air into the second cooking cavity 142. The cooking appliance also includes: a control device 9, connected to the first switch 622 and the second switch 642, for controlling the operation of the first switch 622 and the second switch 642.

[0088] In this embodiment, when cooking ingredients, the state of the first switch 622 can be controlled as needed to control the conduction of the first channel 62 and the second channel 64, thereby controlling the heating object of the heating device 5. In this way, the heating of the first cooking chamber 12 or the heating of the second cooking chamber 142 can be activated according to actual needs, so that the cooking appliance can realize multiple heating modes.

[0089] The control device 9 can control the operation of the first switch 622 and the second switch 642 according to user instructions during use, thereby realizing the electric control of the first switch 622 and the second switch 642.

[0090] In any of the above embodiments, optionally, the cooking appliance includes a first heating mode, a second heating mode and a third heating mode. In the first heating mode, the heating device 5 connects the first inlet 122. In the second heating mode, the heating device 5 connects the second inlet 1422. In the third heating mode, the heating device 5 connects both the first inlet 122 and the second inlet 1422.

[0091] In this embodiment, the cooking appliance has different operating modes, wherein the energy efficiency of the first heating mode is lower than that of the second heating mode. That is, the energy efficiency of the cooking appliance when cooking through the second cooking chamber 142 is greater than that when cooking through the first cooking chamber 12. In other words, the second cooking chamber 142 can achieve more efficient (faster) cooking compared to the first cooking chamber 12. During use, the user can control the cooking appliance to operate according to different operating modes as needed.

[0092] For example, when heating a large amount of food, the first heating mode can be selected for regular heating via the first cooking chamber 12. When heating a small amount of food, the second heating mode can be selected for rapid heating of a small quantity. For instance, common breakfast ingredients such as corn, eggs, and sweet potatoes can be cooked via the second cooking chamber 142, making the cooking appliance suitable for quick breakfast cooking scenarios. When heating different types of food, the third heating mode can be selected to heat the food simultaneously via the first cooking chamber 12 and the second cooking chamber 142. Of course, when heating a large amount of food, the food can be placed separately in the first cooking chamber 12 and the second cooking chamber 142, and then the third heating mode can be selected to heat the food simultaneously via the first cooking chamber 12 and the second cooking chamber 142. This structure makes the heating modes of the cooking appliance more flexible, better meeting the different heating needs of users and improving the user experience.

[0093] In any of the above embodiments, optionally, as Figures 1 to 13As shown, the cooking appliance also includes: a control panel 2, movably mounted at the first opening 16, for controlling the operation of the cooking appliance; a cover 4 is the control panel 2 or the cover 4 is mounted on the control panel 2, and the control panel 2 has a first position relative to the housing 1 (e.g., Figures 1 to 6 The position shown) and the second position (e.g.) Figures 7 to 13 (as shown in the diagram) In the first position, the control panel 2 covers the first opening 16, and in the second position, the control panel 2 opens the first opening 16.

[0094] In this embodiment, the control panel 2 is used to control the operation of the cooking appliance, such as controlling the working mode of the cooking appliance and adjusting cooking parameters. The control panel 2 and the first cooking cavity 12 can be installed vertically (generally with the control panel 2 located above the first cooking cavity 12) or horizontally (generally with the control panel 2 located to the right of the first cooking cavity 12). The second cooking cavity 142 and the control panel 2 are installed on the same side of the first cooking cavity 12. This can be understood as the second cooking cavity 142 being installed in the control area (non-cooking area) of the cooking appliance. With this arrangement, the second cooking cavity 142 will not occupy the cooking area and will not affect the size of the first cooking cavity 12. Thus, while installing the second cooking cavity 142, it is ensured that the volume of the first cooking cavity 12 will not decrease.

[0095] Meanwhile, the cover 4 serves as the control panel 2, or the cover 4 is mounted on the control panel 2. In this embodiment, the control panel 2 is movably mounted at the first opening 16, allowing the first opening 16 to be opened and closed, thus enabling the opening and closing of the second cooking cavity 142. Alternatively, the cover 4 and the control panel 2 can be considered as an integrated unit. Directly opening the second cooking cavity 142 via the control panel 2 eliminates the need for a separate cover, allowing the control panel 2 to be designed larger. This enables a large-screen (or large-panel) design for the control panel without reducing its area.

[0096] When it is necessary to put or take food into the second cooking cavity 142, the control panel 2 can be opened and moved to the second position to expose the first opening 16. When the food is placed and cooking is needed, or when the second cooking cavity 142 is not in use, the control panel 2 can be returned to the closed position to close the second cooking cavity 142.

[0097] in, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This is a schematic diagram of the control panel 2 of the cooking appliance when it is in the first position. Figure 7 , Figure 8 , Figure 9, Figure 10 , Figure 11 , Figure 12 and Figure 13 This is a schematic diagram of the control panel 2 of the cooking appliance when it is in the closed position.

[0098] Furthermore, the control panel 2 and the second cooking cavity 142 are located above the first cooking cavity 12 in the height direction. Furthermore, the cooking appliance is a built-in cooking appliance.

[0099] In other embodiments, the cover 4 may be separate from the control panel 2. For example, the cover 4 may be located on one side of the control panel 2 (not shown in the figure of this embodiment). Alternatively, the control panel 2 may be located on the door 8 of the cooking appliance to avoid obstructing the second cooking cavity 142 (not shown in the figure of this embodiment).

[0100] In any of the above embodiments, optionally, as Figure 20 As shown, a first inlet 122 is provided on the first cooking chamber 12, and a second inlet 1422 is provided on the second cooking chamber 142. The heating device 5 includes a steam generator 52 and a water tank 54. The steam generator 52 can selectively open the first inlet 122 or the second inlet 1422, or simultaneously open the first inlet 122 and the second inlet 1422, to supply steam to the first inlet 122 and / or the second inlet 1422. The water tank 54 is used to supply water to the steam generator 52. The water tank 54 is detachably installed inside the housing 1 and can enter and exit the housing 1 through the first opening 16.

[0101] In this embodiment, the heating device 5 is a steam heating device. That is, the heating device 5 is mainly used to generate steam and heat water using steam. Further, the heating device 5 includes a steam generating device 52. The steam generating device 52 is used to heat water to generate steam. The heating device 5 may also include a water tank 54, which supplies water to the steam generating device 52 to generate steam. The installation location and structure of the water tank 54 are not limited.

[0102] In one specific embodiment, the water tank 54 can be installed inside the control panel 2. When water is not needed, the water tank 54 can be hidden inside the control panel 2. When water needs to be added, the control panel 2 can be opened for operations such as adding water. This structure allows for the concealed installation of the water tank 54, so that the water tank 54 does not occupy the surface space of the product. This allows for a larger area to be reserved for the control panel 2, facilitating the design of a large screen (or large panel) on the control panel 2.

[0103] In one specific embodiment, since the water tank 54 and the second cooking cavity 142 are smaller than the first cooking cavity 12, the water tank 54 and the second cooking cavity 142 can be set on the same side of the first cooking cavity 12 along the height or width direction of the box body 1. This can make the structural layout of the cooking appliance more reasonable and improve the space utilization of the cooking appliance.

[0104] In any of the above embodiments, optionally, as Figure 20 As shown, the heating device 5 also includes a microwave generator 56 for transmitting microwaves into the first cooking cavity 12 and / or the second cooking cavity 142.

[0105] In this embodiment, the cooking appliance can perform both steam cooking and microwave cooking. During microwave cooking, the microwave generator 56 can input microwaves into the first cooking cavity 12 through the first inlet 122 and into the second cooking cavity 142 through the second inlet 1422. Alternatively, a separate microwave delivery port can be provided to input microwaves into both the first and second cooking cavities 12 and 142.

[0106] In any of the above embodiments, optionally, as Figure 20 As shown, the heating device 5 also includes a first heat radiation device 58, which is installed in the second cooking cavity 142 and is used to radiate heat into the second cooking cavity 142.

[0107] In this embodiment, the second cooking cavity 142 or the food inside it can be heated by the first thermal radiation device 58, so that the food can be baked and heated by the first thermal radiation device 58.

[0108] In any of the above embodiments, optionally, as Figure 20 As shown, the heating device 5 also includes a second heat radiation device 59, which is installed inside the first cooking cavity 12 and is used to radiate heat into the first cooking cavity 12.

[0109] In this embodiment, the first cooking cavity 12 or the food inside it can be heated by the second thermal radiation device 59, so that the food inside the first cooking cavity 12 can be baked and heated by the second thermal radiation device 59.

[0110] In any of the above embodiments, optionally, the volume of the second cooking cavity 142 is less than or equal to 20 liters, for example, the volume of the second cooking cavity 142 can be 15 liters or 10 liters.

[0111] Optionally, the volume of the first cooking cavity 12 is greater than half the volume of the second cooking cavity 142. That is, the volume of the first cooking cavity 12 is more than twice the volume of the second cooking cavity 142. This results in a significant difference in volume between the first cooking cavity 12 and the second cooking cavity 142. When heating through the first cooking cavity 12 and the second cooking cavity 142, the difference in heating speed and energy efficiency is more pronounced. This can significantly enhance the heating advantage of the second cooking cavity 142 and improve its utilization rate.

[0112] In any of the above embodiments, optionally, as Figure 2 , Figure 3 , Figure 18 , Figure 20 and Figure 21 As shown, the housing 1 includes: an outer shell 10; and a rapid heating chamber 14, which is detachably installed inside the outer shell 10, and a second cooking chamber 142 is provided inside the rapid heating chamber 14. Figure 21 As shown, the cooking appliance also includes a sensor 7, which is installed inside the housing 10 and is used to sense whether the rapid heating cavity 14 is installed in place.

[0113] In this embodiment, the housing 1 includes an outer shell 10, which serves as the product's exterior component and protects and houses other parts of the product. A rapid heating chamber 14 is detachably installed within the outer shell 10. The rapid heating chamber 14 is used for rapid cooking and contains a second cooking chamber 142 for holding food. Simultaneously, a sensor 7 is installed within the outer shell 10 to detect whether the rapid heating chamber 14 is properly installed, ensuring that it can be reinstalled correctly after disassembly and ensuring accurate connection between the rapid heating chamber 14 and the steam interface within the outer shell 10. Of course, in other embodiments, a guide structure can be provided to guide the correct installation of the rapid heating chamber 14, in which case the sensor 7 may not be required.

[0114] Furthermore, the sensor 7 can be used to control whether the rapid heating cavity 14 can work, so as to ensure that the rapid heating cavity 14 can only cook when it is installed in place. If the sensor 7 does not detect the rapid heating cavity 14, the rapid heating cavity 14 can be locked.

[0115] In any of the above embodiments, optionally, as Figure 20 and Figure 21 As shown, the second cooking cavity 142 is provided with a second inlet 1422, and the outer shell 10 is provided with an insertion interface 102. When the rapid heating cavity 14 is installed in the outer shell 10, the insertion interface 102 and the second inlet 1422 are detachably connected, and the connection between the insertion interface 102 and the second inlet 1422 is sealed. When the second inlet 1422 is connected, the heating device 5 delivers at least one of steam, microwave and hot air into the rapid heating cavity 14.

[0116] In this embodiment, the second cooking cavity 142 is movably installed inside the housing 1. For example, the second cooking cavity 142 is detachably installed on the housing 1. When the second cooking cavity 142 is correctly installed inside the housing 1, for example, when the second cooking cavity 142 is installed inside the outer shell 10 and is in the first installation state (i.e., the predetermined correct installation state), the connector 102 and the second inlet 1422 are detachably connected, and the connection between the two is sealed. With this structure, after the second cooking cavity 142 is installed in the correct position inside the housing 1 (i.e., the second cooking cavity 142 is in the first installation state relative to the housing 1), the connector 102 and the second inlet 1422 can be quickly connected to ensure that the steam, microwaves, or hot air generated by the heating device 5 can enter the second cooking cavity 142. When it is necessary to remove the second cooking cavity 142 (in other installation states), the connector 102 and the second inlet 1422 can be easily disconnected to ensure that the second cooking cavity 142 can be quickly removed.

[0117] In any of the above embodiments, optionally, as Figure 9 As shown, the cooking appliance also includes a support 3, which can be detachably installed in the second cooking cavity 142 for holding ingredients or ingredient containers.

[0118] In this embodiment, the carrier 3 is installed inside the second cooking cavity 142 to hold food ingredients or food containers. When the second cooking cavity 142 cannot be disassembled, the food ingredients can be removed and placed in by using the carrier 3. Of course, even when the second cooking cavity 142 itself is detachable, the carrier 3 can still be configured to make the removal and placement of food ingredients more flexible.

[0119] In any of the above embodiments, optionally, as Figures 1 to 13 As shown, the cooking appliance also includes a door 8, which is mounted on the housing 1 and used to open and close the first cooking cavity 12. Furthermore, the door 8 is positioned on the housing 1 to avoid the second cooking cavity 142, so that the second cooking cavity 142 can be opened or closed independently, unaffected by the door 8.

[0120] in, Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 and Figure 19 A schematic diagram of the structure of the cooking appliance after removing door 8.

[0121] The first cooking cavity 12 can be a built-in, non-removable structure or a structure that can be pulled out and opened.

[0122] Optionally, in any of the above embodiments, the cooking appliance further includes a vent that communicates with the second cooking chamber 142. The vent ensures that the second cooking chamber 142 is connected to the outside atmosphere, preventing excessive pressure in the second cooking chamber 142 during cooking.

[0123] Optionally, the housing 1 includes an outer shell 10 and an inner liner, with the inner liner installed inside the outer shell 10. The inner liner forms a first cooking cavity 12. A second cooking cavity 142 and a heating device 5 are installed between the outer shell 10 and the inner liner.

[0124] Alternatively, the cooking appliance may be an oven, a steam oven, or a microwave-steam-oven combination appliance.

[0125] The following describes a specific cooking utensil.

[0126] Most common cooking appliances have only one cooking chamber, limiting their use to cooking only one type of food. Cooking different ingredients can easily lead to flavor mixing and poor overall performance. Currently, the market offers products with dual-cavity ovens (top and bottom), dual-cavity air fryers (left and right), and appliances that use removable partitions within the cavities to achieve separate cooking chambers, allowing for the simultaneous preparation of multiple dishes. However, most dual / multi-cavity cooking appliances simply stack two cavities, resulting in either an increased overall size or a reduced volume of individual cavities – essentially equivalent to simply stacking two appliances. Furthermore, appliances with separate chambers, even with partitions, offer a cooking effect similar to that of baking trays or steaming pans, failing to achieve a true breakthrough in user experience.

[0127] Related solutions and their drawbacks:

[0128] 1. Dual-cavity / multi-cavity cooking appliances: These are appliances that simply add a cavity of similar size to the existing cavity, with the total volume of the multiple cavities typically not exceeding five times. Some products also include a stove door to accommodate each cavity.

[0129] 2. Cavity cooking appliances: The original cavity is physically separated by partitions or cooking accessories such as baking trays.

[0130] Among them, dual-cavity / multi-cavity cooking appliances are either too large in overall size or too small in cavity size. A large size results in a large space requirement, while a small cavity prevents the cooking of large ingredients. Separate-cavity cooking appliances, with their simple physical separation of existing cavities, lead to a reduction in the size of the cavities. Simple separation makes it difficult to achieve a complete seal between the two cavities, easily resulting in problems such as heat leakage, air leakage, water leakage, and microwave leakage. This solution is more suitable for single-function cooking and cannot support different cooking methods such as grilling, steaming, and microwaving.

[0131] This embodiment aims to solve the problems of existing dual-cavity / multi-cavity / separate-cavity products, which increase the overall size of the machine or reduce the food cooking space in the cavities, as well as the problems of heat leakage, air leakage, water leakage, and microwave leakage between the cavities of separate-cavity products.

[0132] In this embodiment, the dual-cavity cooking appliance adds a second cooking cavity (142) with a volume less than 15 liters to the outside of the original cavity (i.e., the first cooking cavity 12). This cavity can be configured with cooking functions such as microwave, steam, or grilling, or other functions such as sterilization and cleaning, and can work simultaneously with the original cavity. Specifically, the newly added small cooking cavity is located behind the control panel 2. Crucially, the control panel 2 can move between a stationary position and an exposed position. In the stationary position, the control panel 2 covers the small cooking cavity, preventing the user from approaching it; in the exposed position, the small cooking cavity is exposed. Food placed in the small cooking cavity can be removed in three ways: 1. Removed together with the small cooking cavity; 2. Placed in the accessory (carrier 3) of the small cooking cavity and removed together with the accessory (carrier 3); 3. Removed directly from the small cooking cavity. When the small cooking cavity is removable, a sensor is installed behind it to detect this. When the sensor determines that the small cooking cavity is in place, it sends a feedback signal to the cooking appliance, indicating normal operation; otherwise, it cannot.

[0133] This design adds a cooking cavity of less than 15 liters without increasing the overall size of the appliance or reducing the original cavity size. Due to its small volume, it can quickly cook small portions of food, such as buns, corn, sweet potatoes, and chicken wings. When cooking larger portions, the original larger cavity is used. This design meets the needs of rapid cooking for various scenarios and types of food, and eliminates the problems associated with traditional cavity-based designs, such as flavor mixing, air leakage, and wave leakage.

[0134] In addition, the control panel can also be located on the oven door assembly (equivalent to door 8) to avoid obstructing the small cooking cavity.
