Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, specifically to a control method for an integrated cooking device, a computer-readable storage medium, and a computer device. For example, the integrated cooking device of this application, which includes a cooling fan assembly, is more suitable for fully embedded / integrated installation. Background Technology

[0002] Both steaming and baking are cooking methods with significant user demand. Steaming works by continuously supplying high-temperature steam to the food inside the oven, thus cooking the food purely through steaming. Baking works by continuously circulating hot air to the food inside the oven, thus cooking the food through hot air baking. Accordingly, the most basic kitchen appliances are: steam ovens for steaming and ovens for baking. With the increasing sophistication of kitchen appliances, combined steaming and baking (such as a tender baking mode) has emerged. This requires adding steam-generating components to the oven, such as evaporation trays, to provide steam (the cooking medium for steaming), along with corresponding steam delivery pipes and control logic. Because there is some overlap in the cooking medium (steam), steam ovens that combine steaming and baking functions (including baking and steam-baking) have appeared on the market. Furthermore, considering the limited kitchen space for cooking equipment, users have expressed a desire to install as many functional kitchen appliances as possible within a limited space. Therefore, integrated steam ovens can meet this demand. In addition, to accommodate the currently common built-in installation, there are also combination devices on the market such as steam ovens with grills and fryers, and combinations of steam ovens with gas stoves.

[0003] Taking a combination appliance such as a steam oven and a gas stove as an example, for a steam oven, the cooking media for steaming and baking are steam and hot airflow (which may also include steam), respectively. Therefore, there is an inevitable need for heat dissipation during the cooking process, such as dissipating heat from the door assembly (as steam and hot airflow radiate heat to the door assembly, raising its temperature, and considering the door assembly's proximity to the user, heat dissipation is necessary for safety). In addition, there are other structures and components within the cooking appliance that require heat dissipation, such as those located on the top, sides, etc. For these components, their reliability is affected by temperature (on the one hand, the components themselves are heat sources and will heat up due to prolonged operation; on the other hand, the heat radiation from steam and hot airflow to the top of the inner liner where the components are located also causes their temperature to rise). For a gas stove, the area near the cooktop is a heat radiation zone, and its components, which also require heat dissipation, are themselves heat-generating parts. Because cooking appliances have multiple functions, the amount of heat that needs to be dissipated increases. Because cooking equipment is highly integrated, various types of heat may overlap or interfere with each other. Therefore, there is considerable room for improvement in how to effectively dissipate heat from cooking equipment. Summary of the Invention

[0004] This application aims to solve at least part of the above-mentioned technical problems and / or at least part of the above-mentioned technical problems, specifically, how to improve the integration of an integrated cooking device with multiple functions as much as possible while dissipating heat.

[0005] In a first aspect, this application provides a control method for an integrated cooking device, the integrated cooking device comprising: a cooking body; a heat dissipation duct including an air outlet side; and a heat dissipation fan assembly including a heat dissipation box and a heat dissipation fan disposed in the heat dissipation box, the heat dissipation box including a first air inlet, a second air inlet and an air outlet, the control method comprising: operating the heat dissipation fan such that: gas in the heat dissipation duct reaches the heat dissipation fan assembly via the air outlet side and the first air inlet and is discharged through the air outlet; and / or gas in the installation space of the cooking body reaches the heat dissipation fan assembly via the second air inlet and is discharged through the air outlet.

[0006] This configuration allows for heat dissipation from multiple heat radiation zones through bidirectional air intake via the cooling fan assembly, thereby better meeting the equipment's heat dissipation requirements.

[0007] Specifically, the heat dissipation medium from the first air inlet and the second air inlet is collected and discharged centrally through the same cooling fan assembly, which improves the integration of the cooking equipment. It should be noted that the first air inlet and the second air inlet here correspond to the first heat dissipation air inlet and the second heat dissipation air inlet in the specific embodiment.

[0008] It should be noted that the installation space of the cooking body here should be understood as follows: the cooking body includes an outer shell, and an installation space is formed inside the shell. The installation space contains an inner liner that forms the cooking chamber, as well as related structures such as the first heat dissipation duct, components, and heat dissipation fan assembly located outside it. There is a certain margin between the installation space and these structures housed within it. The second air inlet is mainly used to meet the heat dissipation needs of the surface of the structures housed within it and the parts near the surface, such as the installation space on the side or bottom.

[0009] It is understandable that those skilled in the art can determine the specific operating mode of the cooling fan according to actual needs, such as running it throughout the entire process or only in certain stages, with the parameters remaining unchanged or being flexibly adjusted according to cooling requirements.

[0010] In one possible implementation of the control method for the aforementioned integrated cooking equipment, the cooking body includes at least one cooking chamber, which is equipped with a door assembly. The step of "operating the cooling fan so that: gas in the cooling duct reaches the cooling fan assembly via the outlet side and the first inlet and is discharged through the outlet; and / or gas in the installation space of the cooking body reaches the cooling fan assembly via the second inlet and is discharged through the outlet" includes: detecting the state of the door assembly; and when the door assembly is in an open state or about to switch to an open state, adjusting the operating parameters of the cooling fan so that: gas in the cooling duct reaches the cooling fan assembly via the outlet side and the first inlet and is discharged through the outlet; and / or gas in the installation space of the cooking body reaches the cooling fan assembly via the second inlet and is discharged through the outlet.

[0011] This configuration allows for better heat dissipation by adjusting the parameters of the cooling fan when the door assembly is already open or about to be opened. The status of the door assembly can be detected by installing components such as door switches, photoelectric sensors, and position sensors at the corresponding locations on the door assembly.

[0012] Taking adjusting the operating parameters of the hot air blower to increase the speed of the cooling fan as an example, on the one hand, it can increase the heat dissipation rate inside the cooling box and accelerate steam exhaust. On the other hand, the increased speed can create negative pressure in the cooking chamber, which to some extent inhibits the natural steam exhaust when the door is opened, thus effectively preventing users from being directly hit by hot air or reducing the probability / intensity of this phenomenon, thereby improving the user experience.

[0013] If the front exhaust of the cooking equipment is also adjusted to exhaust through other directions that do not directly blow onto the user, the user experience can be improved. For example, if the exhaust direction corresponding to the air outlet has an angle with the horizontal plane, the exhaust direction corresponding to the air outlet is approximately vertical. Here, "approximately vertical" should be understood as: the orientation of the air outlet (which can be the extension of its axis) and / or the airflow direction of the gas discharged through the air outlet can be considered approximately vertical. This could be: having a small angle with the vertical direction (e.g., less than 15°), or being a non-linear direction that is approximately the same as the vertical direction; etc.

[0014] In one possible implementation of the control method for the aforementioned integrated cooking equipment, the integrated cooking equipment has at least one cooking mode. The phrase "operating the cooling fan so that: gas in the cooling duct reaches the cooling fan assembly via the outlet side and the first inlet and is discharged through the outlet; and / or gas in the installation space of the cooking body reaches the cooling fan assembly via the second inlet and is discharged through the outlet" includes: when the cooking program corresponding to the current cooking mode has finished running, adjusting the operating parameters of the cooling fan so that: gas in the cooling duct reaches the cooling fan assembly via the outlet side and the first inlet and is discharged through the outlet; and / or gas in the installation space of the cooking body reaches the cooling fan assembly via the second inlet and is discharged through the outlet.

[0015] This design allows for adjustments to the cooling fan parameters before the door is opened, improving the user experience after the door is opened. Of course, even if the user opens the door immediately after the cooking process ends, the user experience can still be improved appropriately.

[0016] The operating parameters of a cooling fan may include, but are not limited to, speed, power, operating time, and off-state ratio. For example, the cooling fan operates in a combination of multiple stages, with parameters for each stage including speed and duration.

[0017] In one possible implementation, the parameters of the cooling fan are adjusted by increasing the fan speed or power.

[0018] In one possible implementation of the control method for the aforementioned integrated cooking equipment, the cooking body includes at least one cooking chamber, the heat dissipation box includes a third air inlet, and the control method further includes: when the gas pressure in the at least one cooking chamber is greater than a preset value, the gas in the cooking chamber can enter the heat dissipation box through the corresponding third air inlet.

[0019] This configuration allows for further optimization of the equipment's integration and ensures the cooking equipment's operational reliability. Specifically, the first / second air inlets collect and exhaust heat dissipation media from different locations, effectively cooling components and other parts. The third air inlet collects and exhausts gas from the cooking chamber, ensuring the cooking equipment's reliability. It should be noted that the third air inlet here corresponds to the air intake connection structure in the specific embodiment.

[0020] It is understood that those skilled in the art can determine the switching method of the connection state between the third air inlet and the heat dissipation duct and the structure on which it depends, according to actual needs. This may include, but is not limited to: configuring a pressure relief valve at the third air inlet, which opens and discharges some cooking medium when the pressure in the cooking chamber reaches a certain value; or configuring a rotatable or retractable sealing structure at the third air inlet, which, when pressure detection components such as additional pressure sensors detect that the pressure in the cooking chamber reaches a certain value, moves the sealing structure to connect the third air inlet with the heat dissipation duct, thus allowing some cooking medium to be discharged.

[0021] In one possible implementation of the control method for the integrated cooking equipment described above, the heat dissipation duct includes an air inlet side, and the statement that "the gas in the heat dissipation duct reaches the heat dissipation fan assembly via the air outlet side and the first air inlet and is discharged through the air outlet" includes: heat from the door assembly of the integrated cooking equipment enters the heat dissipation duct via the air inlet side, and then reaches the heat dissipation fan assembly via the air outlet side and the first air inlet and is discharged through the air outlet.

[0022] This design allows for a certain degree of cooling of the door components through the heat dissipation duct.

[0023] It is understood that those skilled in the art can determine, based on actual needs, how to enable heat from the door assembly to enter the heat dissipation duct via the air inlet side, such as by placing the air inlet side near the door assembly or aligning the air inlet side with the heat dissipation vents on the door assembly to at least a certain extent.

[0024] In one possible implementation of the control method for the aforementioned integrated cooking equipment, the integrated cooking equipment further includes: a cooktop unit disposed above the cooking body; wherein, the cooktop unit or a position near the cooktop unit is provided with an exhaust area capable of communicating with the external environment, and the phrase "operating the cooling fan so that: gas in the cooling duct reaches the cooling fan assembly via the exhaust side and the first air inlet and is discharged via the exhaust outlet; and / or gas in the installation space of the cooking body reaches the cooling fan assembly via the second air inlet and is discharged via the exhaust outlet" includes: operating the cooling fan so that: gas in the cooling duct is discharged via the exhaust side, the first air inlet, the exhaust outlet, and the exhaust area; and / or gas in the installation space of the cooking body is discharged via the second air inlet, the exhaust outlet, and the exhaust area.

[0025] This configuration allows for the timely upward expulsion of heat-carrying gases.

[0026] In one possible implementation, the cooktop unit includes a cooktop housing with an exhaust area on the cooktop surface. The external environment here can be understood as either directly exhausting into the kitchen space (indoor space) or directly exhausting the gas into the outdoor space via a range hood installed in the cooktop unit.

[0027] In one possible implementation of the control method for the aforementioned integrated cooking equipment, the heat dissipation fan box includes a first heat dissipation chamber and a second heat dissipation chamber that are interconnected. The phrase "operating the heat dissipation fan so that: gas in the heat dissipation duct reaches the heat dissipation fan assembly via the outlet side and the first inlet and is discharged through the outlet; and / or gas in the installation space of the cooking body reaches the heat dissipation fan assembly via the second inlet and is discharged through the outlet" includes: operating the heat dissipation fan so that: gas in the heat dissipation duct reaches the first heat dissipation chamber via the outlet side and the first inlet and is discharged through the outlet; and / or gas in the installation space of the cooking body reaches the second heat dissipation chamber via the second inlet and is discharged through the outlet.

[0028] This configuration allows for effective heat dissipation of the equipment through a combination of dual air inlets and dual chambers. For example, the air outlet can be directly connected to the first and / or second heat dissipation chambers.

[0029] In one possible implementation, the cooking chambers include a plurality of chambers arranged along the width direction, and the third air inlets include a plurality of chambers corresponding to the plurality of cooking chambers. Cooking media within the plurality of cooking chambers can enter the heat dissipation box through their respective third air inlets. This configuration ensures the operational reliability of the cooking equipment by providing separate connections between the cooking chambers.

[0030] In one possible implementation of the control method for the aforementioned integrated cooking device, at least a portion of the heat dissipation fan assembly is disposed on the side of the cooking body; and / or the cooking body includes an evaporation section, at least a portion of which is disposed on the side of the cooking body.

[0031] With this configuration, by placing the heat dissipation fan assembly and / or evaporator on the side of the cooking body, the integration of the cooking equipment along the height direction can be improved, thus reducing the height of the equipment and / or increasing the volume of the cooking chamber from the height direction.

[0032] It is understood that those skilled in the art can determine the structural form of the cooling fan assembly and / or evaporator, specifically which side it is located on, and which part of it is located on the side of the device, according to actual needs. For example, the cooling fan assembly includes two parts, which are respectively located on the same side or different sides of the cooking body.

[0033] In a second aspect, this application provides a computer-readable storage medium including a memory adapted to store a plurality of program codes adapted to be loaded and executed by a processor to perform a control method for an integrated cooking appliance as described in any of the preceding claims.

[0034] It is understood that the computer-readable storage medium has all the technical effects of the control method of the integrated cooking device described in any of the foregoing claims, which will not be repeated here.

[0035] Those skilled in the art will understand that all or part of the processes in the control method of the integrated cooking device of the present invention can be implemented by a computer program instructing related hardware. The computer program can be stored in a computer-readable storage medium, and when executed by a processor, it can implement the steps of the various method embodiments described above. The computer program includes computer program code, which includes, but is not limited to, program code for executing the control method of the integrated cooking device described above. For ease of explanation, only the parts relevant to the present invention are shown. The computer program code can be in the form of source code, object code, executable file, or some intermediate form. The computer-readable storage medium can include: any entity or device capable of carrying the computer program code, a medium, a USB flash drive, a portable hard drive, a magnetic disk, an optical disk, a computer memory, a read-only memory, a random access memory, an electrical carrier signal, a telecommunication signal, and a software distribution medium, etc. It should be noted that the content contained in the computer-readable storage medium can be appropriately added or removed according to the requirements of legislation and patent practice in the jurisdiction. For example, in some jurisdictions, according to legislation and patent practice, the computer-readable storage medium does not include electrical carrier signals and telecommunication signals.

[0036] In a third aspect, this application provides a computer device including a memory and a processor, the memory being adapted to store a plurality of program codes, characterized in that the program codes are adapted to be loaded and run by the processor to perform a control method for an integrated cooking device as described in any of the preceding claims.

[0037] It is understood that this device possesses all the technical effects of the control method for the integrated cooking equipment described in any of the foregoing claims, and will not be elaborated further here. This device can be a computer-controlled device comprising various electronic devices.

[0082] Preferred embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this application and are not intended to limit the scope of protection of this application. For example, although this embodiment is described in conjunction with a steam oven that includes steaming and baking functions (including hot air baking and steam baking) and a cooktop assembly (as in this example, the cooktop assembly includes two cooktop units) positioned above the dual-cavity steam oven, and the steam oven has a dual-cavity structure, this is not intended to limit the scope of protection of this application. Without departing from the principles of this application, those skilled in the art can apply this application to other application scenarios, such as steam oven-fryer, steam oven, etc. Furthermore, the dual-cavity structure of the integrated cooking equipment, including a steaming cavity and a baking cavity, is only an exemplary description. Those skilled in the art can adjust the relative position between the two cavities (e.g., left-right, up-down, etc.) and can flexibly arrange the number and functions of the cavities, such as cavities including one steaming cavity, one baking cavity, one steam baking cavity, one steaming cavity, two baking cavities, etc.

[0083] It should be noted that in the description of this application, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0084] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0085] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can still be implemented without certain specific details. In some examples, the principles of gas stoves and other cooktops familiar to those skilled in the art, as well as steaming / baking functions, are not described in detail in order to highlight the main points of this application.

[0086] The following will refer to the appendix. Figures 1 to 15 The integrated cooking device of this application is described in at least a portion thereof.

[0087] If a steam oven's dual cavities are designed for independent steaming and baking, then both the first cooking cavity (corresponding to the steaming function) and the second cooking cavity (corresponding to the baking function) require steam generating devices such as evaporation trays. Adding an evaporation tray to the second cooking cavity increases the equipment's cost and, to some extent, the complexity of the water circuits related to steam supply. Furthermore, due to the limited water capacity of the evaporation trays and the influence of their heating principle and water replenishment logic, problems inevitably arise during operation, such as yellowing due to dry burning, water overflow due to excessive water replenishment, and scale buildup in the evaporation trays. In such cases, repairs to both systems within the dual cavities are required, increasing maintenance costs. Additionally, the configuration of two evaporation trays and corresponding piping also increases the overall size of the steam oven. Therefore, in this application, the first and second cooking chambers are first equipped with the same steam generating device (such as a steam generator), that is, the same steam generating device serves as the steam source for both chambers. Based on this, corresponding pipelines and logic are configured for both chambers to achieve evaporation supply for both chambers. However, there is still some room for improvement in aspects such as the steam pipelines.

[0088] In one possible implementation, the integrated cooking appliance mainly includes a steam oven 100 and a cooktop unit 200. The cooktop unit 200 is positioned above the steam oven 100, and can be installed in the kitchen using a recessed installation method. This effectively saves installation space and better integrates with the kitchen's decorative style and ambiance. For example, a fully recessed installation is adopted, meaning the cooktop surface of the cooktop unit is roughly flush with other parts (countertops), while the steam oven is located in the cabinet below. The steam oven mainly includes a cooking body 1, a first cooking unit corresponding to the steaming function (e.g., a steam cooking unit 2), a second cooking unit corresponding to the baking function (including pure baking and baking with steaming involved) (e.g., a baking cooking unit 3), and a steam unit 4 that simultaneously supplies steam as the cooking medium to both the first and second cooking units. In this example, the cooking body has two cooking chambers for holding the food to be cooked. That is, in this example, the steam oven has a dual-chamber structure. For example, the cooking body 1 includes two inner pots corresponding to the first cooking unit and the second cooking unit. The two inner pots respectively form a first cooking chamber 11 and a second cooking chamber 12 corresponding to the first cooking unit and the second cooking unit. For example, a shelf can be provided inside the inner pot, so that the food to be cooked can be placed directly on the shelf or placed on a container (such as a plate) placed on the shelf. Alternatively, a shelf structure such as a recessed structure or a rotatable plate can be provided on the inner bottom of the inner pot, so that the food to be cooked can be placed directly on the shelf structure or, after placing the food to be cooked in a container, the bottom of the container can be placed in the position corresponding to the shelf structure. Since the steaming and baking functions are closely related to the temperature of the cooking medium, heating elements such as heating tubes can be installed on the inner top, inner side, and inner bottom of the inner pot. This allows for primary or auxiliary / supplementary heating of the cooking medium (hot airflow circulating in the second cooking chamber and / or steam permeating the first / second cooking chamber) when needed.

[0089] In one possible implementation, the steam unit 4 mainly includes a steam generating device 41 and a first steam pipe and a second steam pipe communicating with the first and second cooking chambers. The steam generating device can be a steam pan, a steam generator, etc. The steam generator is mounted on the back of the cooking body (the mounting space of the cooking body is close to the first cooking chamber) via a mounting structure such as a bracket 411 (e.g., a Z-shaped bracket). The steam generating device mainly includes a steam generating device body and a water storage container (e.g., a clean water box). The steam generating device body forms a steam generating chamber and is equipped with steam generating heating components such as heating pipes. The clean water box is mainly used to supply water (steam generating agent) to the steam generating chamber to generate steam, such as by pumping water into the steam generating chamber via a water pump 42. The water in the steam generating chamber is heated by the heating pipes to generate steam as the cooking medium. The steam piping is mainly used to distribute the generated steam to the first cooking chamber and / or the second cooking chamber, so that: the first cooking chamber, where the food to be cooked is located, is filled with steam, and based on this, the food to be cooked can be cooked by pure steaming through a corresponding control program; and / or steam is added to the second cooking chamber, and based on this, the food to be cooked can be cooked by steam baking or other methods through a corresponding control program. The first steam outlet 431 corresponds to the first evaporation pipe and the second steam outlet 432 corresponds to the second evaporation pipe, and the two steam outlets are positioned as close as possible to the side walls of the cooking body to minimize the probability of steam turbulence occurring between different operating modes.

[0090] In one possible implementation, the steam unit 4 includes a water collection box 44, which is mainly used to collect water accumulated during the cooking process, high-humidity steam in the first cooking chamber, high-temperature and high-humidity gas in the second cooking chamber, and condensate as described below. A drain pump can be configured for the collection box, allowing the collected water to be discharged into a wastewater box, which can be part of the entire unit. The wastewater box can be cleaned and the water emptied periodically. In this example, the water collection box 44 is installed on the lower layer of the Z-shaped bracket, and the steam generator is installed on the upper layer of the Z-shaped bracket. Obviously, those skilled in the art can choose the specific form of the installation structure according to actual needs, such as installing both on two separate structures.

[0091] In this example, a chamber is provided at the bottom of the cooking body, and both the fresh water box and the wastewater box are housed in the chamber at the bottom of the cooking body.

[0092] Based on the cooling fan assembly described below, in addition to the first cooling duct at the top, a vertical cooling duct is also constructed on the back side of the cooking body (the area between the back areas of the two cooking units and the back of the cooking body shell). Compared to the second cooking unit, since the back of the first cooking unit has relatively lower heat, the steam generator and components requiring heat dissipation, such as the electronic control board 16, can be placed on the back side of the cooking body near the first cooking unit. Furthermore, the main body, front cover, and rear cover of the cooling fan box can be made of plastic parts with certain temperature resistance requirements, and the manufacturing process of the cooling fan assembly can be simplified by injection molding.

[0093] In this example, the control board is located below the cooling fan assembly and on the back, away from the side corresponding to the grill cooking unit (along the width direction). The steam generator is located below the cooling fan assembly and near the grill cooking unit (because it needs to supply steam to the grill cooking unit simultaneously). The water collection box is generally located below the control board, and the water pump is generally located below the steam generator. The cooking body has two chambers located below the water collection box and the steam generator, each containing a wastewater box and a clean water box, respectively. Obviously, those skilled in the art can appropriately adjust the placement of the components and their relative positions, such as integrating the steam generator, water collection box, and water pump in other ways, or placing a portion of the control board at the top.

[0094] In one possible implementation, the baking function cooking unit 3 typically includes a fan shroud assembly 31, which is primarily used to provide circulating hot airflow into the second cooking chamber 12. The fan shroud assembly mainly includes a centrifugal fan 311 or other fan (which may be called a temperature equalizer) and heating components such as a heating coil. The temperature equalizer is mainly used to keep the temperature of the hot airflow within the second cooking chamber as low as possible and uniform. To reduce the operating temperature of the temperature equalizer, an insulation structure such as thermal insulation cotton can be installed between the temperature equalizer and the second cooking chamber to effectively prevent continuous heat radiation from the second cooking chamber onto the area of ​​the temperature equalizer. In this example, the fan shroud assembly includes a fan shroud 312, and the cooking body 1 includes a back panel. In this example, the cooking body 1 includes a back cover shell 14, which includes a back panel 141 and two side panels 142 extending forward from both sides of the back panel. A hot air chamber is formed between the back panel 141 and the fan shroud. A centrifugal fan is installed in the hot air chamber. Heating components such as heating coils can be installed in the hot air chamber or in other locations near the hot air chamber. Taking a heating coil as an example, the heating coil can be installed in the hot air chamber, and the centrifugal fan can be installed within the area enclosed by the heating coil.

[0095] Obviously, those skilled in the art can determine the structural form of the fan cover / back panel, its position relative to the cooking body, and the connection method between the two according to actual needs. For example, the back panel may be a separate structure. In this example, the aforementioned back panel is located on the side of the cooking body furthest from the user (e.g., the rear side). Obviously, besides the rear side, the back panel can also be located on other sides (e.g., the left or right side). The fan cover and back panel can be connected to each other by snap-fit, screw-fit, welding, etc., or they can be integrally formed.

[0096] Furthermore, the combination of the back panel and the fan shroud is merely an exemplary description of the formation of a hot air chamber. Those skilled in the art can determine the specific form of the hot air chamber according to actual needs. For example, the fan shroud may be provided with a constraint structure that allows the aforementioned centrifugal fan to be installed in and removed from the hot air chamber. This constraint structure may include several limiting pieces arranged circumferentially within the hot air chamber that can pivot relative to the fan shroud. In this way, it can be considered that the fan shroud and the constraint structure form the hot air chamber, or that the back panel and the fan shroud with the added constraint structure form the hot air chamber.

[0097] It should be noted that the hot air chamber mentioned here is not necessarily a complete chamber, but rather should be understood as a mounting location for accommodating the centrifugal fan and heating coil. Therefore, those skilled in the art can determine the structural form and communication configuration of the hot air chamber according to actual needs. For example, the centrifugal fan and heating coil can be placed in the same chamber or in two separate connected chambers. The hot air chamber can communicate with the second cooking chamber through multiple connecting holes, or it can communicate with the second cooking chamber by making a certain part of it an open structure.

[0098] For example, the fan shroud has a return air vent near the centrifugal fan, and the fan shroud also has an air supply vent, which is positioned roughly around or partially around the return air vent. The centrifugal fan includes a motor and a fan; the motor drives the fan to rotate facing the return air vent, and the fan's rotation draws air from the inner chamber through the return air vent into the hot air chamber. In this example, the heating coil is positioned within the hot air chamber corresponding to the return air vent, and the fan is positioned within the area enclosed by the heating coil. Thus, under the action of the fan, the air from the inner chamber is drawn into the hot air chamber through the return air vent, heated by the heating coil, and transformed into a hot airflow carrying heat, serving as the cooking medium. The fan then propels this hot airflow towards the outer air supply vent and back into the inner chamber. This cycle continuously delivers hot air to the surface of the food to be cooked, allowing the food to be cooked using a hot air roasting method according to the corresponding control program.

[0099] In one possible implementation, the cooking body 1 is provided with an openable (e.g., pivotally open vertically / horizontally) door assembly on the side near the user's operation (e.g., the side facing the user, which can usually be called the front side). For example, each of the two inner pots may be equipped with a door assembly, the two inner pots may share a door assembly (e.g., the door assembly may be a rigid structure or may include two relatively movable door parts), or after each of the two inner pots is equipped with a door assembly, an additional door assembly shared by both (two layers of doors) may be added. In this example, the door assembly includes a first door assembly 151 and a second door assembly 152 corresponding to the steaming cooking unit and the baking cooking unit, respectively.

[0100] In general, to ensure the performance of integrated cooking equipment, the working environment of the door, power board, and temperature-sensitive electrical components (such as those located on the top or back of the cooking unit) needs to be within a certain temperature range. Combining steaming, baking, and cooktop units can generate more heat within a limited space. This necessitates more effective heat dissipation for the integrated cooking equipment. While integrated steaming and baking units can better meet user needs—for example, allowing simultaneous steaming and baking using dual-cavity operation—the fact that different functional units all involve heat sources during operation can lead to cross-contamination and overlapping of heat sources, potentially causing poor heat dissipation.

[0101] In one possible implementation, the integrated cooking device includes a first heat dissipation part 5 disposed in the steam oven. The first heat dissipation part includes a first heat dissipation duct 51 and a heat dissipation fan assembly 52. ​​In this example, the first heat dissipation duct is disposed at the top of the cooking body. The heat dissipation fan assembly is mainly used to draw air through the first heat dissipation duct to the position corresponding to the heat dissipation fan assembly and then discharge it, thereby dissipating heat from the power board, electrical components, etc., as mentioned above, to ensure their operational reliability.

[0102] Typically, the cooling fan assembly is a cross-flow fan located at the top of the cooking body and connected to the first cooling duct. However, a top-mounted structure can affect the expansion space at the top of the inner pot to some extent, significantly increasing the dimensions of the device in the height direction and limiting the potential for increasing the volume of the inner pot in the height direction. Therefore, in this application, the cooling fan assembly is located on the side of the cooking body.

[0103] In this example, the cooling fan assembly 52 is located on the rear side of the cooking body. More specifically, in this example, the cooling fan assembly is located on the rear side of the cooking body corresponding to the position of the steaming cooking unit. This reduces the dimensions of the device in the height direction, making the device more compact and thus improving the integration of the device to some extent.

[0104] In one possible implementation, the cooling fan assembly 52 mainly includes a cooling box 521 and a first cooling fan 522. For example, if the first cooling fan is a centrifugal fan, the cooling box 521 mainly includes a box body 5211, a first cover 5212 (which may be called a front cover) disposed on the front side of the box body, and a second cover 5213 (which may be called a rear cover) disposed on the rear side of the box body. A first cooling chamber 5214 (which may be called a front cooling chamber) is formed between the box body and the front cover, and a second cooling chamber 5215 (which may be called a rear cooling chamber) is formed between the box body and the rear cover. The first cooling chamber 5214 and the second cooling chamber 5215 are interconnected. The first cooling fan 522 is installed inside the cooling box. In this example, part of the first cooling fan 52 is located in the front cooling chamber and part is located in the rear cooling chamber, thus the two cooling chambers can be connected by the installation of the first cooling fan. Alternatively, the first cooling fan can be located in only one of the two cooling chambers, and the two cooling chambers can be connected to each other through a connecting structure such as a connecting hole.

[0105] Obviously, the combination of the front and rear cover plates and the main body of the air box is only one exemplary configuration of the heat dissipation air box. For example, the front cover plate can be replaced by the rear wall of the inner liner or the two (front cover plate and rear wall of the inner liner) can be integrally formed, that is, the heat dissipation air box and the rear wall of the inner liner form a heat dissipation chamber. In addition, those skilled in the art can determine the structural form, coverage area, and connection method between the front / rear cover plates and the main body of the air box according to actual needs.

[0106] In one possible implementation, the cooling fan box has a first cooling air inlet 5216 connected to the first cooling chamber, and a second cooling air inlet 5217 and a cooling air outlet 5218 connected to the second cooling chamber. The first air outlet side of the first cooling duct can connect to the first cooling air inlet, and the second cooling air inlet can directly connect to the rear space of the cooking body of the integrated cooking device. In this example, the first cooling air inlet and the cooling air outlet are located on the top of the cooling fan box, and the second cooling air inlet is located on the rear side of the cooling fan box.

[0107] In order to allow the gas to be better discharged through its heat dissipation outlet 5218, the heat dissipation air box is provided with a heat dissipation air outlet guide structure 5219 at the position corresponding to the heat dissipation air outlet. The heat dissipation air outlet guide structure can be a slope, an arc surface, or a combination of related structures, such as a combination of slopes, an arc surface, or a combination of slopes and arc surfaces.

[0108] In this way, with the high-speed operation of the centrifugal fan, two negative pressure zones will be formed at the positions corresponding to the first heat dissipation chamber and the second heat dissipation chamber (such as being referred to as the first negative pressure zone / front negative pressure zone corresponding to the first heat dissipation chamber and the second negative pressure zone / rear negative pressure zone corresponding to the second heat dissipation chamber, respectively).

[0109] In the first negative pressure zone, guided by the first cooling fan, air entering the first cooling duct from the first air inlet side enters the first cooling chamber through the first cooling air inlet and is discharged through the cooling air outlet. The connection between the first cooling air inlet and the first air outlet side of the first cooling duct can be achieved by direct connection (such as socketing), indirect connection through an intermediate pipe section, or alignment (such as without connection).

[0110] The gas in the rear space of the cooking unit heats up after cooling the relevant components inside. In the second negative pressure zone, guided by the first cooling fan, the heated gas enters the second cooling chamber through the second cooling inlet and is then discharged through the cooling outlet.

[0111] As can be seen, the combination of the cooling fan assembly (first cooling air inlet) and the first cooling air duct can dissipate heat from the relevant components in the top area of ​​the integrated cooking device. By opening a second cooling air inlet for the cooling fan assembly, heat can be dissipated from the relevant components in the back area of ​​the integrated cooking device.

[0112] Obviously, the structural form, number, location, and connection method of the first / second heat dissipation air inlet and outlet are merely exemplary descriptions, and those skilled in the art can flexibly adjust them according to actual needs. For example, the heat dissipation air outlet can be directly connected to both the first and second heat dissipation chambers (in this example, the first heat dissipation air inlet is connected to the first heat dissipation chamber, the first heat dissipation chamber is connected to the second heat dissipation chamber, and the second heat dissipation chamber is connected to the heat dissipation air outlet), etc. The implementation of the direct connection between the heat dissipation air outlet and both the first and second heat dissipation chambers can include, but is not limited to, two heat dissipation air outlets, the air inlet side of the heat dissipation air outlet being connected to both the first and second heat dissipation chambers respectively, or the heat dissipation air outlet including two upstream branch pipes connected to both the first and second heat dissipation chambers respectively, and a downstream main pipe connected to both branch pipes respectively, etc.

[0113] In one possible implementation, the first heat dissipation duct 51 simultaneously covers both the steaming and baking cooking units along the width of the device, thus more effectively achieving the heat dissipation function of the device. The first heat dissipation duct may include one or more. In the case of multiple first heat dissipation ducts, the structural form of the multiple first heat dissipation ducts and their arrangement at the top can be flexibly adjusted. For example, multiple sub-heat dissipation ducts extend from the first air outlet side of the first heat dissipation duct, and the first air inlet side of each sub-heat dissipation duct connects to different areas, such as a heat-generating component, the side of the cooking body, another first heat dissipation duct, or a non-heat-generating area (i.e., where natural air can be drawn into the first heat dissipation duct).

[0114] In one possible implementation, the first air inlet side 511 of the first heat dissipation duct is located on the front side of the cooking unit, such as in the front door frame of the cooking unit, while the first air outlet side 512 is connected to the heat dissipation air inlet of the first heat dissipation duct assembly on the rear side. In this way, the first heat dissipation duct spans two cooking units in the width direction of the cooking unit, and the roughly diagonally arranged heat dissipation paths on the right front and left rear further increase the length of the first heat dissipation duct, thus potentially providing more efficient heat dissipation for the relevant components.

[0115] It should be noted that the diagonal arrangement mentioned here should be understood as follows: after the arrangement direction in the front and rear directions is roughly determined, the first air inlet side and the first air outlet side are staggered to a certain extent in the left and right directions, thereby appropriately increasing the length of the first heat dissipation air duct.

[0116] In one possible implementation, the first air inlet side of the first heat dissipation duct is located in the heat dissipation area (e.g., the heat dissipation area is provided with a heat dissipation vent) of the second door assembly 152 corresponding to the baking function cooking unit, such as being at least partially aligned with or near the heat dissipation vent of the second door assembly. In this way, the heat dissipation fan assembly can dissipate heat from the heat-generating components in the top area while also sharing at least a portion of the heat dissipation for the second door assembly.

[0117] It should be noted that the alignment of the heat dissipation area of ​​the second door assembly with at least a certain degree of alignment mentioned here should primarily be understood as directional alignment. Since the first and second door assemblies for the steaming / baking cooking unit are arranged adjacent to each other, the cooling fan assembly can not only dissipate heat from the second door assembly but also handle a portion of the heat dissipation from the first door assembly. Preferably, for better heat dissipation from the mechanical energy of the first door assembly, the first cooling duct can be widened near the first air outlet side to ensure that it is at least partially aligned with the heat dissipation areas of both the first and second door assemblies. Alternatively, a connecting hole or an extension can be added to the first cooling duct near the first air outlet side to guide heat from the first door assembly 151.

[0118] Furthermore, with the cross-flow fan positioned at the top of the cooking unit, the air carrying heat is typically expelled forward through the door gaps of the door assembly. This front-mounted heat dissipation method causes heat to blow directly onto the user (as in this example, roughly at the user's legs), thus reducing the user experience.

[0119] In one possible implementation, the integrated cooking appliance includes an exhaust structure arranged at an angle to the horizontal direction, capable of discharging heated air upwards. This allows the heated air to be discharged upwards at a large angle (e.g., ≥60°) to the horizontal direction. For example, it may be discharged in a generally vertical direction. The exhaust structure can be a separate addition or a collaborative structure integrated with the components of the integrated cooking appliance. For instance, the exhaust structure could be a heat dissipation vent, an upwardly extending heat dissipation duct connected to the vent, or a structure connected to the upper cooktop unit. Taking the exhaust duct as an example, its downstream side could be connected to the indoor space, directly to the outdoor environment, or connected to the outdoor environment via a duct (e.g., the duct of a range hood).

[0120] In this example, the integrated cooking appliance includes a cooktop unit 200 located above the steam oven. The heat dissipation vent 5212 can be positioned above the heat dissipation box, connecting to the cooktop surface of the cooktop unit and thus switching the heat exhaust from front to top. A range hood is typically installed above the cooktop unit (e.g., on the top or side), which can promptly remove the exhaust air carrying heat, preventing a rise in indoor temperature. The connection between the heat dissipation vent and the cooktop surface can be achieved through various means, such as configuring ductwork, adding connecting holes to the cooktop surface, or directly aligning at least a portion of the heat dissipation vent with the exhaust opening on the cooktop surface.

[0121] In one possible implementation, the cooking body is provided with exhaust and depressurization communication structures corresponding to the steaming and baking cooking units, respectively (e.g., referred to as the first exhaust communication structure and the second exhaust communication structure, respectively, which are connected to the heat dissipation fan box, so that the depressurized gas can be discharged through the aforementioned heat dissipation vent under the action of the first heat dissipation fan). The exhaust communication structure may include one or more communication holes.

[0122] In this example, the first and second air outlet communication structures include a communication hole with a certain radial dimension (which can be understood as the radial dimension of the communication hole being larger than the radial dimension of each single hole in the porous structure (mesh)). For example, the first and second air outlet communication structures are respectively provided at the back of the cooking body corresponding to the first / second cooking chamber. At the corresponding position of the heat dissipation box (near the wall of the first / second cooking chamber), two air inlet communication structures are provided (such as the first air inlet communication structure 52111 and the first air inlet communication structure 52112 respectively). In this way, when the heat dissipation box is in working condition, the gas discharged from the first / second cooking chamber through the first / second air outlet communication structure can be discharged upward together through the heat dissipation air outlet. For example, the first / second air inlet communication structure can be connected to the aforementioned first heat dissipation chamber and / or second heat dissipation chamber (for example, in this example, the first / second air inlet communication structure is connected to the second heat dissipation chamber near the heat dissipation air outlet). Similarly, the upward-exhausted gas can be promptly removed by the range hood at the top / side of the cooktop. However, unlike the air from the first heat dissipation duct mentioned earlier, which carries heat and needs to be rerouted for exhaust, the gas (cooking medium) from the first / second cooking chambers is exhausted and depressurized to ensure cooking quality within those chambers. Since this gas is part of the cooking medium, especially the gas from the cooking chambers which often contains oil and other contaminants, timely removal ensures cleanliness. Of course, the cooking medium from both chambers also carries heat; therefore, this method also prevents the indoor space from overheating.

[0123] Obviously, placing a pair of air vents adjacent to the back of the cooking body is only a preferred implementation. For example, one can be placed on the back of the cooking body while the other is still placed on the top (connected to the first heat dissipation duct), both air vents can be placed on the top, or the two air vents can be placed non-adjacent (such as one connected to the back of the heat dissipation box, and one connected to the side / top / bottom of the heat dissipation box, etc.).

[0124] Compared to the current method of setting a pressure relief vent at the top of the inner pot, by setting two air outlet connection structures close to each other and connecting them to the heat dissipation fan assembly respectively, the integration of the equipment is improved while ensuring cooking reliability.

[0125] Furthermore, for both the first cooking chamber and the second cooking chamber during steam intervention, some steam condenses during exhaust. Therefore, a drainage structure (such as a drain outlet or drain pipe) 52113 is provided on the cooling fan box, for example, a drainage structure is provided near the bottom of the cooling fan box. Condensate can be discharged through this drainage structure. In this example, the drainage structure has a drain outlet with a connecting pipe. Through the cooperation of a drainage connection structure such as a rubber hose with the connecting pipe, the condensate can be diverted to the aforementioned water collection box and further discharged to a wastewater box or other structure / device capable of collecting condensate, thereby ensuring the cleanliness of the equipment.

[0126] In this example, the main body of the air box includes a vertically arranged partition. The outer edge of the partition extends towards the first and second heat dissipation chambers, respectively, forming a first flange and a second flange. The first flange, the partition, and the front cover form the first heat dissipation chamber, and the second flange, the partition, and the rear cover form the second heat dissipation chamber. A drainage structure is located within the second heat dissipation chamber corresponding to the heat dissipation outlet. For example, a drainage structure may be provided at the bottom of the second flange, and this drainage structure may consist of a drain outlet with a connecting pipe extending below (outer bottom of the main body of the air box). To ensure better condensation collection, the bottom wall of the air box can be positioned lower than other locations relative to the height of the drainage structure. For example, the bottom wall of the air box can be configured to converge towards the drainage structure (e.g., a curved surface, an inclined surface, etc.).

[0127] Since gas condensation is more likely to occur near the heat dissipation vent, the drainage structure is located in the second heat dissipation chamber, which is directly connected to the vent. This allows for flexible adjustment of the drainage outlet's position depending on how the vent is adjusted. Alternatively, a drainage structure can also be installed in the first heat dissipation chamber.

[0128] Obviously, the combination of the above-mentioned partition and two flanges is only an exemplary structural form of the bellows body. Those skilled in the art can flexibly adjust it according to actual needs, such as the two parts of the bellows body being connected to each other after the two parts form the first and second heat dissipation chambers with the front and rear covers respectively.

[0129] In one possible implementation, a drainage structure can be provided on the heat dissipation box, allowing condensate generated within the heat dissipation box to flow to a location corresponding to the aforementioned drainage structure and / or back to the first / second cooking chamber. The drainage structure may include a guide plate, a guide groove, a funnel-shaped guide pipe, etc. Drainage structures can be provided separately for the first and second cooking chambers, or one or more drainage structures can be provided without specific targeting, focusing solely on the angle from which condensate is generated within the heat dissipation box. For example, the drainage structure is a downwardly inclined planar / curved guide plate disposed along the width of the heat dissipation box, allowing condensate to reach the drainage structure at the bottom via the guide plate.

[0130] In this example, the drainage structure includes a first drainage structure 52114 corresponding to the first cooking chamber and a second drainage structure 52115 corresponding to the second cooking chamber. The first / second drainage structures are guide channels, and their structures are substantially the same. Further, in this example, the first / second drainage structures are positioned corresponding to the aforementioned first / second air intake communication structure. This allows condensate generated in the cooling fan box to flow back into the first / second cooking chamber via the first / second drainage structure, the first / second air intake communication structure, and the first / second air outlet communication structure. This backflow can be complete or partial (e.g., a portion flows back into the first / second cooking chamber, and a portion is guided to the drainage structure).

[0131] In one possible implementation, the first / second exhaust connection structure and the first / second intake connection structure are located on the back of the heat dissipation fan box near the top. Thus, taking full backflow as an example, during the condensate collection process, the first / second drainage structure can perform a first-stage condensate recovery, meaning the first condensate recovery structure returns the recovered condensate to the first / second cooking chamber. A second-stage condensate recovery can be performed through a drainage structure, meaning the second condensate recovery structure discharges the recovered condensate to a wastewater box or other condensate collection structure (in the case of partial backflow, the second condensate recovery structure can supplement the first condensate recovery structure, recovering the portion of condensate collected by the first / second drainage structure that did not return to the first / second cooking chamber). To achieve full backflow, the guide channel can be angled towards the cooking chamber.

[0132] Obviously, the fact that the first and second drainage structures are largely the same, and that they are aligned and connected with the first and second air intake communication structures, is merely an exemplary description. Those skilled in the art can flexibly choose the structural form of the first and second drainage structures and the method of achieving backflow according to actual needs. For example, the structural form of the first and second drainage structures and the method of achieving backflow can also be different. For example, the first or second drainage structure is an inclined guide plate, and the lowest point of the guide plate is connected to the first or second cooking chamber through a connecting hole, connecting pipe, or other connecting structure.

[0133] In this example, the cooling fan box is located at the back of the cooking unit. The cooling fan box has a roughly volute-like structure. Viewed along the width of the back of the cooking unit, the cooling fan box includes a first fan box section and a second fan box section. The first fan box section has a first cooling air inlet at its upper part and a second cooling air inlet at its back. The second fan box section has a cooling air outlet at its upper part. A first cooling fan is located in the first fan box section, and the second fan box section is roughly located near the middle of the cooking unit. The first / intake communication structure is located near the first and second cooking chambers, respectively. This allows for a more compact cooling fan assembly. Obviously, those skilled in the art can flexibly adjust the structure of the cooling fan box, the structure of the first / second fan box section, and the positions of the first / second cooling air inlets and outlets to adapt to specific needs. For example, the cooling air outlet can be widened, another cooling air outlet path can be extended, or the second intake communication structure can be located near the middle of the second cooking chamber.

[0134] In one possible implementation, the integrated cooking device includes a second heat dissipation section 8 disposed in the cooktop unit 200. For example, the cooktop unit 200 mainly includes a cooktop shell 6, which has two cooktop mounting positions. Two cooktops 7 are mounted on the two cooktop mounting positions, and the second heat dissipation section 8 is disposed inside the cooktop shell. Obviously, those skilled in the art can determine the structural form, number, and distribution of each cooktop mounting position (in the case of multiple cooktops) on the cooktop surface according to actual needs.

[0135] In one possible implementation, the second heat dissipation section 8 mainly includes a second heat dissipation duct 81 and a second heat dissipation fan 82. The second heat dissipation fan 82 has a second air inlet side and a second air outlet side. If the second heat dissipation fan is a cross-flow fan, the air inlet of the cross-flow fan is connected to the environment inside the stove shell, the air outlet of the cross-flow fan is connected to the second air inlet side of the second heat dissipation duct, and the second air outlet side of the second heat dissipation duct is connected to the external environment. In this way, the cross-flow fan can promptly cool heat-generating components such as electronic components inside the stove shell.

[0136] In one possible implementation, the air inlet of the cross-flow fan is located on the side of the stove closer to the operator (e.g., the front side), and the air outlet of the cross-flow fan faces the side of the stove furthest from the operator (e.g., the rear side). The second air outlet of the second heat dissipation duct is located on the side of the stove furthest from the operator. It is understood that, similar to the aforementioned first heat dissipation section, those skilled in the art can determine the manner in which the air outlet of the second heat dissipation duct connects to the external environment according to actual needs, such as by utilizing the existing structure of the stove or by adding structures / components such as connecting ports or pipes.

[0137] In one possible implementation, both the second air outlet side of the second heat dissipation duct and the heat dissipation air outlet of the heat dissipation fan assembly are located near the rear of the cooktop assembly, and both need to exhaust gas into the external environment. Therefore, in this example, a shared exhaust structure is provided on the cooktop unit.

[0138] On the one hand, those skilled in the art can determine the structural form of the exhaust structure according to actual needs, such as an exhaust pipe, exhaust port, exhaust hood, etc. On the other hand, it is obvious that the location of the exhaust structure does not necessarily have to be close to the rear of the stove unit; that is, provided that exhaust can be achieved, those skilled in the art can also adjust the exhaust position of the exhaust structure.

[0139] Furthermore, sharing a single exhaust structure is only a preferred embodiment. Those skilled in the art can set up two independent exhaust structures according to actual needs, and the exhaust positions of the two exhaust structures can be the same or different. For example, it may include, but is not limited to: the exhaust structure includes a main pipe and two branch pipes extending from the main pipe, the two branch pipes being connected to the exhaust positions of the first / second heat dissipation air duct respectively; the exhaust structure includes two closely arranged exhaust pipes, the two exhaust pipes being directly connected to the external environment or connected to the external environment through the same exhaust port.

[0140] In one possible implementation, the cooktop surface (upper surface of the cooktop shell 6) of the cooktop shell 6 is provided with an exhaust area 61 as a common exhaust structure. This exhaust area can be an open structure, with exhaust holes, exhaust mesh, etc. For example, a range hood positioned on the side or top of the cooktop can promptly extract the gas delivered to the exhaust area 61. Thus, in this embodiment, three types of heat-carrying gases can be discharged through the exhaust area 61: one is heat-carrying gas from the first heat dissipation duct (mainly used to cool the door assembly and top heat-generating components of the steam oven), another is cooking medium from the first / second cooking chamber (mainly used for pressure relief and exhaust to ensure the cooking reliability of the steam oven), and the third is heat-carrying gas from the second heat dissipation duct (mainly used to cool the heat-generating components inside the cooktop unit).

[0141] In one possible implementation, in order to ensure that the exhaust area 61 of the cooktop can be better connected with the heat dissipation outlet of the heat dissipation fan assembly, and to prevent the heat-carrying gas from entering the environment inside the cooktop shell, an exhaust connection structure 62 can be provided between the first exhaust port and the exhaust area. For example, the exhaust connection structure 62 can be a corrugated pipe, a rigid pipe, a baffle, etc.

[0142] As can be seen, in the preferred embodiment of this application, by arranging the cooling fan assembly at the back of the cooking body and using a vertically arranged centrifugal fan, the space at the top of the inner liner is effectively freed up. This allows for both a further increase in the volume of the inner liner along the height direction and a reduction in the dimensions of the device along the height direction, such as by reducing the height of the top of the front door frame of the cooking device. By setting the cooling fan box as a dual-chamber / air inlet configuration, the integrated cooking device can be adequately cooled at one location through dual air intakes. By integrating the cooling and exhaust / pressure relief structures corresponding to the two cooking chambers into the cooling fan box, the cooking medium used for exhaust / pressure relief to ensure cooking reliability can be discharged along with the cooling air. That is, the first cooling fan located at the back of the cooking body can not only cool the door assembly and related structures at the top / side, but also ensure the cooking reliability of the device by providing a path for the depressurized gas. By converging the exhaust positions (air vents) of the first heat dissipation section and the exhaust positions (second exhaust side) of the second heat dissipation section and connecting them with the exhaust area on the cooktop assembly, the heat dissipation gases from the steam oven and cooktop assembly, as well as the cooking medium released from the exhaust pressure of the steam oven, can be centrally discharged, improving the integration of the equipment. Simultaneously, the exhaust area can be modified by changing the exhaust side corresponding to the first heat dissipation duct from front to top, preventing heat from being directly sprayed onto the user's body (e.g., roughly to the user's legs), thereby enhancing the user experience.

[0143] Based on the above structure, the present invention also provides a control method for an integrated cooking device. In this example, the speed of the cooling fan is adjusted by detecting the open state of the first / second door assembly. As a result, after the user opens the first / second door assembly, the cooling speed is accelerated and a negative pressure is better formed in the cooking chamber, which significantly improves the user's experience when being directly hit by hot air.

[0144] For example, the steaming and baking cooking units each include one or more cooking modes. Taking the baking mode as an example, one such mode might include a first stage, a second stage, and a third stage. The first stage is the initial stage, where the temperature of the hot air gradually increases. The second stage is the main cooking stage, where the hot air remains at a stable temperature for a relatively long time (e.g., 25-35 minutes). During the third stage, the cooking of the food is nearly complete and takes a relatively short time. At the end of the third stage, the temperature of the hot air is still high, and the user will experience a noticeable rush of hot air when the door assembly is opened. In this example, the first / second door assembly is equipped with a door control switch. When the door assembly is opened, the controller will increase the speed of the first cooling fan based on the door opening action detected by the door control switch.

[0145] Main reference Figure 16Based on the preferred embodiment of this application and the integrated cooking device with the above-described structure, in one possible implementation, the control method of the integrated cooking device mainly includes the following steps:

[0146] S1601, Detect the status of the first / second door assembly.

[0147] In this example, the baking mode corresponding to the second cooking chamber is being run, so the status of the second door assembly is being detected.

[0148] S1602. Determine whether the first / second door assembly is in the open state or has a tendency to be switched to the open state. If yes, proceed to S1603; if no, continue with the current heat dissipation operation parameters (S1604).

[0149] If, after the current cooking program (in this example, for ease of description, the operation of the first cooling fan is discussed independently of the cooking program) has ended, and the door control switch detects an open state, it can be considered that the door assembly is likely to be switched to the open state. Whether the door is in the open state can be detected by an image detection device or a photoelectric sensor.

[0150] S1605. Increase the speed of the first cooling fan (from the original first speed to the second speed).

[0151] Under normal circumstances, after the steaming / baking cooking program is completed, the first cooling fan will be activated to enter the cooling program (the aforementioned cooking program, which includes multiple stages, can also be considered as a steaming / baking program, and the steaming / baking program and the cooling program together are called a complete cooking program). This will allow the temperature inside the integrated chamber cooking equipment to drop to near room temperature as quickly as possible, thereby ensuring the lifespan of the equipment's components and preventing the frame and other structures within the frame from being exposed to high temperatures for extended periods.

[0152] In this way, the gas in the first heat dissipation duct is discharged upward through the exhaust path of the first heat dissipation air inlet → the first heat dissipation chamber → the second heat dissipation chamber → the heat dissipation air outlet → the heat dissipation exhaust area, and the gas in the space behind the cooking body is discharged upward through the exhaust path of the second heat dissipation air inlet → the second heat dissipation chamber → the heat dissipation air outlet → the exhaust area.

[0153] S1604. After the heat dissipation program related to the first heat dissipation fan is completed (such as operating parameters such as running time and running speed), the first heat dissipation fan stops running, and the program related to this cooking stops.

[0154] It should be noted that although the steps in the above embodiments are described in a specific order, those skilled in the art will understand that, in order to achieve the effects of the present invention, different steps do not necessarily have to be executed in this order. They can be executed simultaneously or in other orders, and some steps can be added, replaced, or omitted. For example, it could be: not detecting the open state of the first / second door assembly, and immediately increasing the speed of the first cooling fan after the cooking program ends; when a tendency for the door assembly to be opened is detected, first preventing the door assembly from being opened and increasing the parameters of the first cooling fan; etc.

[0155] It should be noted that although the control method of the integrated cooking equipment constructed in the above specific manner has been described as an example, those skilled in the art will understand that the present invention is not limited thereto. In fact, users can flexibly adjust the relevant steps and parameters in the steps according to actual application scenarios, such as adjusting the speed of the cooling fan to a non-constant speed multi-speed combination operation mode.

[0156] The technical solutions of this application have been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
