Description

Technical Field

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

[0002] 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. Solutions have emerged such as dual-cavity ovens (top and bottom), dual-cavity air fryers (left and right), and products that use removable partitions within the cavities to achieve multi-cavity cooking, allowing for the simultaneous preparation of multiple dishes. However, these dual / multi-cavity cooking appliances often simply stack two cavities, resulting in either an increased overall size or a reduced cavity volume – essentially equivalent to simply stacking two appliances. Furthermore, multi-cavity cooking appliances using partitions offer a similar effect to using baking trays or steaming pans, failing to achieve a true breakthrough in user experience.

[0003] Therefore, how to design a dual-cavity (multi-cavity) cooking appliance that can operate independently without increasing the overall size of the product or reducing the volume of the original cooking cavity has become an urgent problem to be solved. Summary of the Invention

[0004] This application aims to address the problems that, when cooking appliances in related solutions achieve dual-cavity (multi-cavity) cooking, the overall size of the appliance may increase or the volume of the cavities may decrease, and when cooking in separate cavities through partitions, the flavors of the food may easily mix.

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

[0006] An embodiment of this application provides a cooking appliance, including: a housing, in which a first cooking cavity and a second cooking cavity are disposed, the second cooking cavity being located outside the first cooking cavity; and a heating device for heating food in 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, and along the height direction of the cooking appliance, the second cooking cavity is located below the first cooking cavity, or the second cooking cavity is located on one side of the first cooking cavity along the width direction of the cooking appliance.

[0007] A cooking appliance according to an embodiment of this application includes a housing and a heating device. 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 first cooking cavity, as the main cooking area of ​​the appliance, has a larger 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 breakfast and other similar cooking scenarios. 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] Furthermore, since the second cooking cavity is separately located outside the first cooking cavity, the first and second cooking cavities are completely independent and can be completely isolated from each other. This avoids the problem of flavor mixing between the first and second cooking cavities when cooking simultaneously. Moreover, this arrangement does not require separating the first cooking cavity, allowing cooking to be done simultaneously through both the first and second cooking cavities. This allows for the addition of a smaller second cooking cavity without increasing the overall size of the appliance or reducing the original cavity size. This enables the simultaneous cooking of large quantities and multiple types of ingredients, meeting the needs of rapid cooking in various scenarios and with multiple ingredients. It also eliminates the problems associated with compartmentalized solutions, such as flavor mixing, air leakage, and microwave leakage. This solves the problems of dual-cavity / multi-cavity / compartmentalized products, which often fail to increase the overall size of the appliance or reduce the food cooking space within the cavities, as well as the problems of heat leakage, air leakage, water leakage, and microwave leakage between compartmentalized products.

[0009] 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.

[0010] In any of the above embodiments, optionally, the cooking appliance further includes: a door, mounted on the housing, for opening or closing the first cooking cavity; wherein, along the height direction of the cooking appliance, the height position of the second cooking cavity is lower than the height position of the door; or the second cooking cavity is located on one side of the door along the width direction of the cooking appliance.

[0011] In this embodiment, the door is used to open or close the first cooking cavity. The second cooking cavity is located at the bottom of the first cooking cavity along its height, or on the left or right side of the first cooking cavity along its width. This arrangement ensures that the second cooking cavity is not covered by the door, allowing cooking to be performed without opening the door. This ensures that the operation of the two cavities does not interfere with each other, improving the independence and ease of use of the cooking space.

[0012] In any of the above embodiments, the cooking appliance may optionally include: a door, mounted on the housing, for opening or closing the first cooking cavity; wherein, when the door closes the first cooking cavity, the second cooking cavity is located inside the door.

[0013] In this embodiment, the second cooking cavity is located on the rear side of the door, that is, the second cooking cavity is covered by the door. This allows the second cooking cavity to be hidden behind the door, making the overall appearance of the product more integrated and the product more aesthetically pleasing.

[0014] In any of the above embodiments, optionally, the second cooking cavity is fixedly disposed in the box body, and the box body is provided with a food inlet and outlet, which are connected to the second cooking cavity; the cooking appliance further includes: a cover body, installed on the box body, for opening or closing the food inlet and outlet; or a door body, installed on the box body, for opening or closing the first cooking cavity, and for opening or closing the second cooking cavity.

[0015] In this embodiment, the second cooking cavity is embedded within the housing, and the food inlet / outlet communicates with it. Food can be placed into or removed from the second cooking cavity through the inlet / outlet. A cover can be installed on the housing to open or close the second cooking cavity. In this case, the second cooking cavity may not be covered by a door, or it may be located inside the door. Alternatively, the second cooking cavity can be located inside the door without a cover, allowing it to be opened or closed via the door. When designing the second cooking cavity, the opening and closing method can be appropriately determined based on its location.

[0016] In any of the above embodiments, optionally, the housing includes: an outer shell, the outer shell including a mounting cavity and a mounting port communicating with the mounting cavity; a rapid heating cavity, detachably installed in the mounting cavity and capable of being moved into or out of the mounting cavity through the mounting port; the cooking appliance further includes: a cover, installed on the housing, for opening or closing the mounting port; or a door, installed on the housing, for opening or closing the first cooking cavity and for opening or closing the mounting port.

[0017] 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 cavity is detachably installed within the outer shell. The rapid-heating cavity is used for quick cooking and includes a second cooking chamber for holding food. This structure allows the second cooking chamber to exist independently of the outer shell, facilitating cleaning of the second cooking chamber.

[0018] For this type of structure, a separate cover can be provided for opening or closing the installation port, or the installation port can be opened or closed directly through a door. When designing the second cooking cavity, the opening and closing method of the second cooking cavity can be reasonably set according to its location.

[0019] In any of the above embodiments, optionally, the housing includes: an outer shell, the outer shell including a mounting cavity and a mounting port communicating with the mounting cavity; and a rapid heating cavity, the rapid heating cavity having a drawer-type structure, which can be pulled out and installed on the housing between an open position and a closed position.

[0020] In any of the above embodiments, optionally, the rapid heating cavity is slidably disposed on the housing between the open position and the closed position.

[0021] In this embodiment, the rapid heating chamber is designed as a pull-out drawer structure. This allows the rapid heating chamber to be opened and closed quickly by pulling it out, making it convenient to put in and take out food.

[0022] When the rapid heating chamber is in the open position, at least a portion of the rapid heating chamber is located outside the chamber, and when the rapid heating chamber is in the closed position, at least a portion of the rapid heating chamber is located inside the chamber.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] In any of the above embodiments, optionally, the cooking appliance further includes: a first channel connecting the heating device and the first inlet, wherein a first switch is provided on the first channel for opening or closing the first channel to conduct the connection between the heating device and the first inlet or to block the connection between the heating device and the first inlet; a second channel connecting the heating device and the second inlet, wherein a second switch is provided on the second channel for opening or closing the second channel to conduct the connection between the heating device and the second inlet or to block the connection between the heating device and the second inlet; and a control device connected to the first switch and the second switch for controlling the operation of the first switch and the second switch.

[0027] In this embodiment, when cooking food, the state of the first switch can be controlled as needed to control the conduction of the first and second channels, thereby controlling the heating object of the heating device. This allows the heating of either the first or second cooking cavity to be activated as needed, enabling the cooking appliance to achieve multiple heating modes. Specifically, the control device can turn on the first switch or the second switch alone to supply steam to one of the cooking cavities, or it can turn on both switches simultaneously to supply steam to both cooking cavities at the same time.

[0028] 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.

[0029] 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 connects to the first inlet. In the second heating mode, the heating device connects to the second inlet. In the third heating mode, the heating device connects to both the first and second inlets simultaneously.

[0030] 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 cavity is greater than that when cooking through the first cooking cavity. In other words, the second cooking cavity achieves more efficient (faster) cooking compared to the first cooking cavity. During use, the user can control the cooking appliance to operate according to different modes as needed.

[0031] 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, allowing the appliance to meet the needs of quick breakfast cooking scenarios. 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. Of course, when heating a large amount of food, the food can be placed separately into 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 the different heating needs of users and improving the user experience.

[0032] In any of the above embodiments, optionally, the second cooking cavity is fixedly disposed within the housing, the housing is provided with a food inlet and outlet, the food inlet and outlet are connected to the second cooking cavity, and the cooking appliance also includes a water tank, which is detachably disposed at the food inlet and outlet and seals the food inlet and outlet; or the housing includes an outer shell and a rapid heating cavity, the outer shell includes an installation cavity and an installation port communicating with the installation cavity, the rapid heating cavity is detachably installed in the installation cavity and can be moved into or out of the installation cavity through the installation port, and the cooking appliance includes a water tank, which is detachably disposed at the installation port, wherein the rapid heating cavity is connected to the water tank, or the rapid heating cavity and the water tank are independently installed in the outer shell.

[0033] In this embodiment, when the second cooking cavity is a built-in design, the water tank can be detachably installed at the food inlet and outlet and the food inlet and outlet can be sealed. In this way, the water tank can act as a cover to close or open the food inlet and outlet, thereby simplifying the product structure.

[0034] When the second cooking cavity is formed within the detachable rapid-heating cavity, the water tank can be detachably positioned at the mounting port and the port sealed. This allows the water tank to act as a cover, enabling the opening and closing of the food inlet and outlet, thus simplifying the product's structure. Furthermore, the rapid-heating cavity and water tank can be connected together, allowing both to be removed from the casing simultaneously. That is, the rapid-heating cavity can be removed directly when the water tank is removed, facilitating user operation. Alternatively, the rapid-heating cavity and water tank can be independent, each mounted separately on the outer casing. In this case, the water tank can be removed first, followed by the rapid-heating cavity.

[0035] The first cooking chamber is provided with a first inlet, and the second cooking chamber is provided with a second inlet. The heating device includes a steam generator, which 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, and / or the water tank is used to collect wastewater discharged from the first cooking chamber and / or the second cooking chamber.

[0036] 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 can supply water to the steam generator for steam generation, or the water tank can also be used as a wastewater container. Exemplarily, the water tank can be used both to supply water to the steam generator and as a wastewater container for wastewater collection.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] In any of the above embodiments, optionally, the housing includes an outer shell and a rapid heating cavity. The outer shell includes a mounting cavity and a mounting port communicating with the mounting cavity. The rapid heating cavity is detachably installed in the mounting cavity and can be moved into or out of the mounting cavity through the mounting port. The cooking appliance also includes a sensor installed in the outer shell for sensing whether the rapid heating cavity is installed in place.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] In any of the above embodiments, the cooking appliance may optionally include a carrier, which is detachably installed in the second cooking cavity for holding food ingredients or food containers.

[0052] 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.

[0053] In any of the above embodiments, the cooking appliance may optionally include a door mounted on the housing for opening and closing the first cooking chamber.

[0054] The first cooking cavity can be a built-in, non-removable structure, or it can be a pull-out and openable structure.

[0055] 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.

[0056] 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.

[0057] Alternatively, the cooking appliance may be an oven, a steam oven, or a microwave-steam-oven combination appliance.

[0058] Optionally, the cooking appliance is a countertop cooking appliance.

[0059] Optionally, the cooking appliance also includes a control panel. The control panel is located on the door.

Detailed Implementation

[0086] 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.

[0087] The cooking appliance according to an embodiment of this application will now be described with reference to the accompanying drawings.

[0088] like Figures 1 to 22 As shown, an embodiment of this application provides a cooking appliance, including a housing 1 and a heating device 5. 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. Along the height direction of the cooking appliance, the second cooking cavity 142 is located below the first cooking cavity 12, or the second cooking cavity 142 is located on one side of the first cooking cavity 12 along the width direction of the cooking appliance (not shown in the figures of this embodiment).

[0089] The cooking appliance according to an embodiment of this application includes a housing 1 and a heating device 5. 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 in the first cooking cavity 12 and / or 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 cavities in cooking appliances resulting in slow cooking speeds and energy waste when cooking small portions of food.

[0090] 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 they are cooking simultaneously. Furthermore, this configuration eliminates the need to separate the first cooking cavity 12. This allows for simultaneous cooking through both the first and second cooking cavities 142, enabling simultaneous cooking in both cavities. This allows for the addition of a smaller second cooking cavity 142 without increasing the overall size of the appliance or reducing the original cavity size. This balances the simultaneous cooking of large quantities and multiple types of ingredients, meeting the needs of rapid cooking in various scenarios and with multiple ingredients. It also eliminates the problems associated with compartmentalized solutions, such as flavor mixing, air leakage, and microwave leakage. This solves the problems of dual-cavity / multi-cavity / compartmentalized products, which often fail to achieve the same result without increasing the overall size of the appliance or reducing the food cooking space within the cavities. It also addresses the issues of heat leakage, air leakage, water leakage, and microwave leakage between compartmentalized products.

[0091] 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 or they can all be set to the same type of heating device. 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.

[0092] In any of the above embodiments, optionally, as Figures 9 to 20 As shown, the cooking appliance also includes: a door 8, mounted on the housing 1, for opening or closing the first cooking chamber 12. Further, as... Figure 9 , Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, along the height direction of the cooking appliance, the height position of the second cooking cavity 142 is lower than the height position of the door 8; or the second cooking cavity 142 is located on one side of the door 8 along the width direction of the cooking appliance (not shown in the figure of this embodiment).

[0093] In this embodiment, the door 8 is used to open or close the first cooking cavity 12. The second cooking cavity 142 is disposed at the bottom of the first cooking cavity 12 along the height direction, or on the left or right side of the first cooking cavity 12 along the width direction. This arrangement ensures that the second cooking cavity 142 is not covered by the door 8, so that the second cooking cavity 142 can be opened for cooking without opening the door 8, making the operation of the two cavities independent and improving the independence and ease of use of the cooking space.

[0094] In any of the above embodiments, optionally, as Figures 9 to 20 As shown, the cooking appliance also includes: a door 8, mounted on the housing 1, used to open or close the first cooking cavity 12. Wherein, Figure 15 As shown, when the door 8 closes the first cooking cavity 12, the second cooking cavity 142 is located inside the door 8. Wherein, Figure 15 In the middle, the second cooking cavity 142 is obscured by the door 8 and is not visible.

[0095] In this embodiment, the second cooking cavity 142 is located on the rear side of the door 8, that is, the second cooking cavity 142 is covered by the door 8. This allows the second cooking cavity 142 to be hidden behind the door 8, making the overall appearance of the product more integrated and the product more aesthetically pleasing.

[0096] In any of the above embodiments, optionally, as Figure 14 As shown, the second cooking cavity 142 is fixedly installed inside the housing 1. The housing 1 is provided with a food inlet / outlet 18, which communicates with the second cooking cavity 142. The cooking appliance also includes: a cover 4, installed on the housing 1, for opening or closing the food inlet / outlet 18; or a door 8, installed on the housing 1, for opening or closing the first cooking cavity 12, and the door 8 is also used to open or close the second cooking cavity 142 (not shown in the figure of this embodiment).

[0097] In this embodiment, the second cooking cavity 142 is embedded within the housing 1. The food inlet / outlet 18 communicates with the second cooking cavity 142, allowing food to be placed into or removed from it. A cover 4 can be installed on the housing 1 to open or close the second cooking cavity 142. In this case, the second cooking cavity 142 may not be covered by the door 8, or it may be located inside the door 8. Alternatively, the second cooking cavity 142 may be located inside the door 8 without a cover 4, allowing it to be opened or closed via the door 8. When designing the second cooking cavity 142, the opening and closing method can be appropriately determined based on its location.

[0098] In any of the above embodiments, optionally, as Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 11 , Figure 12 and Figure 13As shown, the housing 1 includes: an outer shell 10, the outer shell 10 including a mounting cavity 104 and a mounting port 16 communicating with the mounting cavity 104; a rapid heating cavity 14, which is detachably installed in the mounting cavity 104 and can be moved into or out of the mounting cavity 104 through the mounting port 16; the cooking appliance also includes: a cover 4, installed on the housing 1, for opening or closing the mounting port 16; or a door 8, installed on the housing 1, for opening or closing the first cooking cavity 12, and for opening or closing the mounting port 16 (not shown in the figure of this embodiment).

[0099] 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 includes a second cooking chamber 142 for holding food ingredients. This structure allows the second cooking chamber 142 to exist independently of the outer shell 10, facilitating cleaning of the second cooking chamber 142.

[0100] For this structure, a separate cover 4 can be provided to open or close the mounting port 16, or the mounting port 16 can be opened or closed directly through the door 8. When designing the second cooking cavity 142, the opening and closing method of the second cooking cavity 142 can be reasonably set according to its location.

[0101] In any of the above embodiments, optionally, the housing 1 includes: an outer shell 10, the outer shell 10 including a mounting cavity 104 and a mounting port 16 communicating with the mounting cavity 104; and a rapid heating cavity 14, the rapid heating cavity 14 having a drawer-type structure (not shown in the figure of this embodiment), which can be pulled out and installed on the housing 1 between an open position and a closed position.

[0102] In any of the above embodiments, optionally, the rapid heating cavity 14 is provided on the housing 1 in a retractable manner between the open position and the closed position.

[0103] In this embodiment, the rapid heating cavity 14 is configured as a pull-out drawer structure. This allows the rapid heating cavity 14 to be quickly opened and closed by pulling it out, facilitating the loading and unloading of food.

[0104] When the rapid heating chamber 14 is in the open position, at least a portion of the rapid heating chamber 14 is located outside the housing 1, and when the rapid heating chamber 14 is in the closed position, at least a portion of the rapid heating chamber 14 is located inside the housing 1.

[0105] In any of the above embodiments, optionally, as Figure 21 and Figure 22As shown, the first cooking cavity 12 is provided with a first inlet 122, and the second cooking cavity 142 is provided with a second inlet 1422; the heating device 5 can selectively open the first inlet 122 or the second inlet 1422, or simultaneously open the first inlet 122 and the second inlet 1422. When the first inlet 122 is opened, the heating device 5 delivers 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 delivers at least one of steam, microwave and hot air into the second cooking cavity 142.

[0106] 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.

[0107] 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.

[0108] In any of the above embodiments, optionally, as Figure 21 and Figure 22 As shown, the cooking appliance also includes: a first channel 62, connecting the heating device 5 and the first inlet 122, with a first switch 622 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; a second channel 64, connecting the heating device 5 and the second inlet 1422, with a second switch 642 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; and 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.

[0109] In this embodiment, when cooking food, 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 cavity 12 or the heating of the second cooking cavity 142 can be activated according to actual needs, so that the cooking appliance can realize multiple heating modes.

[0110] 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.

[0111] Specifically, the control device 9 can turn on the first switch 622 or the second switch 642 separately to supply steam to one of the cooking chambers. The control device 9 can also turn on the first switch 622 and the second switch 642 simultaneously to supply steam to both cooking chambers at the same time.

[0112] 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.

[0113] 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 cavity 142 is greater than that when cooking through the first cooking cavity 12. In other words, the second cooking cavity 142 can achieve more efficient (faster) cooking compared to the first cooking cavity 12. During use, the user can control the cooking appliance to operate according to different operating modes as needed.

[0114] For example, when heating a large amount of food, the first heating mode can be selected for regular heating via the first cooking cavity 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 cavity 142, allowing the appliance to meet the needs of 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 cavity 12 and the second cooking cavity 142. Of course, when heating a large amount of food, the food can be placed separately in the first cooking cavity 12 and the second cooking cavity 142, and then the third heating mode can be selected to heat the food simultaneously via both cavities. This structure makes the heating modes of the appliance more flexible, better meeting the different heating needs of users and improving the user experience.

[0115] In any of the above embodiments, optionally, as Figures 1 to 20As shown, the second cooking cavity 142 is fixedly installed inside the housing 1. The housing 1 is provided with a food inlet / outlet 18, which is connected to the second cooking cavity 142. The cooking appliance includes a water tank 54, which is detachably installed at the food inlet / outlet 18 and seals the food inlet / outlet 18. Alternatively, the housing 1 includes an outer shell 10 and a rapid heating cavity 14. The outer shell 10 includes a mounting cavity 104 and a mounting port 16 connected to the mounting cavity 104. The rapid heating cavity 14 is detachably installed inside the mounting cavity 104 and can be moved into or out of the mounting cavity 104 through the mounting port 16. The cooking appliance includes a water tank 54, which is detachably installed at the mounting port 16. The rapid heating cavity 14 is connected to the water tank 54, or the rapid heating cavity 14 and the water tank 54 are independently installed inside the outer shell 10.

[0116] In this embodiment, when the second cooking cavity 142 is a built-in design, the water tank 54 can be detachably installed at the food inlet / outlet 18 and the food inlet / outlet 18 can be sealed. In this way, the water tank 54 can act as a cover 4 to close or open the food inlet / outlet 18, thereby simplifying the product structure.

[0117] When the second cooking cavity 142 is formed within the detachable rapid heating cavity 14, the water tank 54 can be detachably installed at the mounting port 16 and the mounting port 16 can be closed. This allows the water tank 54 to act as a cover 4, enabling the opening or closing of the food inlet / outlet 18, thus simplifying the product structure. Furthermore, the rapid heating cavity 14 and the water tank 54 can be connected together so that both can be removed from the housing 1 simultaneously. That is, the rapid heating cavity 14 can be removed directly when the water tank 54 is removed, facilitating user operation. Alternatively, the rapid heating cavity 14 and the water tank 54 can be independent of each other, with both installed independently on the outer casing 10. In this case, the water tank 54 can be removed first, followed by the rapid heating cavity 14.

[0118] Optionally, such as Figures 1 to 22 As shown, the first cooking chamber 12 is provided with a first inlet 122, and the second cooking chamber 142 is provided with a second inlet 1422. The heating device 5 includes a steam generator 52, which 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 deliver 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, and / or the water tank 54 is used to collect wastewater discharged from the first cooking chamber 12 and / or the second cooking chamber 142.

[0119] 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 can supply water to the steam generating device 52 for steam generation, or the water tank 54 can also be used as a wastewater container. Exemplarily, the water tank 54 can be used both to supply water to the steam generating device 52 and as a wastewater container for wastewater collection.

[0120] In any of the above embodiments, optionally, as Figure 21 and Figure 22 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.

[0121] 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.

[0122] In any of the above embodiments, optionally, as Figure 21 and Figure 22 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.

[0123] 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.

[0124] In any of the above embodiments, optionally, as Figure 21 and Figure 22 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.

[0125] 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.

[0126] 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.

[0127] In any of the above embodiments, optionally, half the volume of the first cooking cavity 12 is greater than the volume of the second cooking cavity 142.

[0128] Furthermore, half the volume of the first cooking cavity 12 is greater than the volume of the second cooking cavity 142, meaning 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 becomes more pronounced. This significantly enhances the heating advantage of the second cooking cavity 142 and improves its utilization rate.

[0129] In any of the above embodiments, optionally, as Figure 21 and Figure 22 As shown, the housing 1 includes an outer shell 10 and a rapid heating cavity 14. The outer shell 10 includes a mounting cavity 104 and a mounting port 16 communicating with the mounting cavity 104. The rapid heating cavity 14 is detachably installed in the mounting cavity 104 and can be moved into or out of the mounting cavity 104 through the mounting port 16. The cooking appliance also includes a sensor 7, which is installed in the outer shell 10 and is used to sense whether the rapid heating cavity 14 is installed in place.

[0130] 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.

[0131] 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.

[0132] In any of the above embodiments, optionally, as Figure 21 and Figure 22As 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.

[0133] 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.

[0134] In any of the above embodiments, optionally, as Figure 20 As shown, the cooking appliance also includes a carrier 3, which is detachably installed in the second cooking cavity 142 for holding food or food containers.

[0135] 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.

[0136] In any of the above embodiments, the cooking appliance may optionally include a door 8, which is mounted on the housing 1 and is used to open and close the first cooking cavity 12.

[0137] The first cooking cavity 12 can be a built-in, non-removable structure or a structure that can be pulled out and opened.

[0138] In any of the above embodiments, the cooking appliance may optionally include 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.

[0139] 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.

[0140] Alternatively, the cooking appliance may be an oven, a steam oven, or a microwave-steam-oven combination appliance.

[0141] Optionally, the cooking appliance is a countertop cooking appliance.

[0142] Optionally, the cooking appliance also includes a control panel 2. The control panel 2 is located on the door 8.

[0143] in, Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 This is a structural diagram showing the open state of the door 8 of the cooking appliance. Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 , Figure 19 and Figure 20 This is a structural diagram showing the cooking appliance's door 8 when it is closed.

[0144] The following describes a specific cooking appliance.

[0145] Most cooking appliances in the relevant solutions have only one cooking chamber, limiting their use to cooking only one type of food. If different ingredients are cooked, flavors can easily mix, resulting in poor performance. Currently, some dual-cavity ovens, dual-cavity air fryers, and products with removable partitions within the cavities allow for separate cooking, enabling the simultaneous preparation of multiple dishes. However, common dual / multi-cavity cooking appliances simply stack two cavities, often resulting in an increased overall size or reduced cavity volume – essentially equivalent to simply stacking two appliances. While separate-cavity appliances use partitions, the effect is similar to using baking trays or steaming pans, failing to achieve a true breakthrough in user experience.

[0146] Related solutions and their disadvantages:

[0147] 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 door to accommodate each cavity.

[0148] 2. Partitioned cooking appliances: The original cavity is physically divided by partitions or cooking accessories such as baking trays.

[0149] Among them, dual-cavity / multi-cavity cooking appliances: the overall size of the appliance is too large, or the cavity size is too small. The large size will result in taking up too much space, and the small cavity will make it impossible to cook large ingredients. Separate-cavity cooking appliances: simple physical separation of existing cavities will lead to a reduction in the size of the cavity. Simple separation of cavities makes it difficult to achieve a complete seal between the two cavities, which can easily lead to problems such as heat leakage, air leakage, water leakage, and microwave leakage. This solution is more suitable for single-function cooking and is difficult to achieve different cooking methods such as grilling, steaming, and microwave cooking.

[0150] 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.

[0151] In this embodiment, the dual-cavity cooking appliance adds a second cooking cavity (142) with a volume of less than 10 liters to the outside of the original cavity (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 at the bottom or side of the original cavity, or behind the oven door (door 8). If the cavity is located at the bottom or side, the user can access the cover of the small cooking cavity directly to place or remove food without opening the oven door. If the cavity is located behind the oven door, the cooking cavity is blocked by the oven door, and the cooking food can only be removed from the cooking cavity after opening the oven door. Food placed in the small cooking cavity can be removed in three ways: removed along with the cooking cavity; placed in an accessory compartment of the small cooking cavity and removed along with the accessory; or removed directly from the cooking cavity. When the cooking cavity can be removed, a sensor is installed at the rear of the cooking cavity to sense it. When the sensor determines that the cooking cavity is in place, it sends a feedback signal to the cooking appliance, which can then work normally; otherwise, it cannot.

[0152] This structure adds a cooking cavity of less than 10 liters without increasing the overall size of the appliance or reducing the size of the original cavity. 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 large cavity is used normally. This design meets the needs of rapid cooking for various scenarios and ingredients, and avoids the problems associated with separate cavity designs, such as flavor mixing, air leakage, and wave leakage. Furthermore, the control panel 2 can also be mounted on the oven door assembly (equivalent to door 8) to avoid obstructing the small cooking cavity.
