Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, specifically to an integrated built-in cooking device. 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 steam oven as an example, 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 at the top, sides, etc. For example, the reliability of these components 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 cavity where the components are located also causes their temperature to rise). Furthermore, to ensure the reliable operation of the cooking appliance, when the pressure inside the cooking chamber exceeds a certain value, some of the cooking media needs to be discharged. Obviously, the discharged cooking media also carries heat. Because the cooking appliance has multiple functions, the amount of heat that needs to be dissipated / the amount of heat-carrying media discharged will increase. Because cooking equipment has a certain degree of integration, various heat sources may overlap or interfere with each other. Therefore, under the premise of effectively dissipating heat from the cooking equipment and timely expelling the heat-generating gases / heat-carrying cooking media, there is considerable room for improvement in how to maximize the integration of the 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, it aims to improve the integration of the equipment as much as possible while ensuring that the heat-carrying gas (heat dissipation medium, cooking medium) is discharged in a timely manner.

[0005] In view of this, this application provides an integrated built-in cooking device, the device comprising: a cooking unit including a first heat dissipation part, the first heat dissipation part including a heat dissipation fan assembly having an air outlet and at least one air inlet; a cooktop unit including a cooktop shell and a second heat dissipation part, the second heat dissipation part including a cooktop second heat dissipation duct disposed within the cooktop shell, the cooktop shell having an exhaust area capable of communicating with the external environment; and an exhaust connection assembly including an exhaust connection body, the exhaust connection body being removably disposed in the cooking unit and / or the cooktop unit; wherein, the exhaust connection body forms a connection duct, the connection duct being respectively connected to the heat dissipation fan assembly and the second heat dissipation duct, so that at least a portion of the gas from the air outlet of the heat dissipation fan assembly and the gas from the second heat dissipation duct can reach the exhaust area via the exhaust connection body.

[0006] This configuration allows for the timely removal of heat-carrying gases from the cooking and cooktop units through the exhaust area, ensuring the heat dissipation performance of the integrated cooking appliance. The exhaust connection components further facilitate smoother gas exhaust. Furthermore, the slight intersection of the exhaust paths in the downstream sections of the two units, by merging the exhaust paths of the heat-carrying gases, improves the overall integration of the appliance. The external environment here can be understood as either directly exhausting into the kitchen space (indoor space) or directly exhausting the gases to the outdoor space via the range hood located in the cooktop unit.

[0007] Furthermore, the removable configuration allows for flexible connection between the two units via the exhaust connection assembly, enabling the heat-carrying medium discharged from the cooling fan assembly to be expelled through the exhaust area, thus avoiding phenomena such as hot air blowing on the legs and improving the user experience.

[0008] It is understood that those skilled in the art can determine the structural form / material of the exhaust connection body, the specific removable connection method, and whether it is removable in one of the two units or removable relative to both units, based on actual needs. For example, the exhaust connection body can be set in the cooking unit / stove unit by means of snap-fit, adhesive, screw connection, etc. The exhaust connection body can be a one-piece structure or a structure of several parts connected together. The exhaust connection body can be a rigid structure or a structure that can produce a certain degree of deformation.

[0009] In one possible implementation of the above-mentioned integrated cooking device, the exhaust connection body is magnetically attached to the cooking unit and / or the cooktop unit.

[0010] This configuration provides a possible form that can be removed.

[0011] For example, the exhaust connection body can be magnetically attached to one or both of the cooking unit and the cooktop unit. Taking a connection to both as an example, the principle / structure, number, and number of components of the magnetic connection parts corresponding to the two magnetic attachments can be the same or different. The magnetic connection parts corresponding to the two magnetic attachments can include one component, multiple separate components, or multiple interconnected components. The magnetic connection parts can be permanent magnet components or electromagnets with switchable magnetism (e.g., changing magnetic attraction to magnetic repulsion, generating magnetic attraction, or removing magnetic attraction).

[0012] In one possible implementation of the aforementioned integrated cooking device, the exhaust connection assembly includes a magnetic connection component disposed on the side of the exhaust connection body near the cooking unit.

[0013] This configuration provides a specific connection relationship for magnetic adsorption. Based on this, after the cooking unit is installed, simply align the side of the exhaust connector closest to the cooking unit roughly with the air outlet of the cooling fan assembly to complete the installation.

[0014] In one possible implementation of the aforementioned integrated cooking device, the magnetic connection component is a one-piece structure or comprises multiple sub-components. The magnetic connection component is disposed on the cooking unit in such a way that it surrounds at least a portion of the air outlet of the cooling fan assembly. Alternatively, the exhaust connection assembly includes a pressure plate disposed on the side of the exhaust connection body near the cooktop unit. The pressure plate, the exhaust connection body, and the cooktop unit are fixedly connected by fasteners. Furthermore, the exhaust connection body is a structure capable of extending and retracting between the cooking unit and the cooktop unit.

[0015] This configuration provides possible structural forms and connection methods for the exhaust connection assembly.

[0016] By surrounding the air outlet with magnetic connecting components, a certain amount of counterweight can be applied, facilitating alignment and ensuring accurate installation. When tightly arranged around the entire circumference, it can also provide a seal to prevent gas leakage.

[0017] The pressure plate can be a ring structure, multiple strip structures, multiple block structures, etc. It can include multiple strip structures, such as multiple strip structures that can be roughly combined into a ring structure or include a pair of parallel pressure plates. The number and position of the connection points on each pressure plate can be flexibly adjusted according to actual needs. Based on this, the exhaust connection body can be installed to the cooktop unit first, and then the cooktop unit can be installed to the cooking unit.

[0018] For example, the exhaust connection body can be stretchable in only one dimension, or it can also allow a certain degree of deformation within the horizontal plane. For instance, the exhaust connection body includes two rigid structures that can move relative to each other to achieve stretching, or it can be a flexible structure such as a bellows that can not only stretch but also allow a certain degree of lateral displacement.

[0019] In one possible implementation of the above-mentioned integrated cooking device, the cooktop shell is provided with an exhaust cover plate having a communicating structure at a position corresponding to the exhaust area.

[0020] This design effectively prevents foreign objects from entering the cooktop unit / steam oven through the exhaust connection assembly, thus ensuring the cleanliness of the integrated cooking equipment.

[0021] In one possible implementation of the aforementioned integrated cooking device, the cooking unit includes a first heat dissipation duct, and the heat dissipation fan assembly includes: a heat dissipation box having at least one air inlet, the at least one air inlet including a first air inlet and a second air inlet; and a heat dissipation fan disposed in the heat dissipation box; wherein, gas in the first heat dissipation duct can enter the heat dissipation box through the first air inlet; and wherein, the second air inlet communicates with the installation space of the cooking body.

[0022] This configuration allows for better heat dissipation of the equipment in different areas through bidirectional air intake. Specifically, by collecting the heat dissipation medium from the first and second air inlets and discharging it centrally through a single cooling fan assembly, the heat dissipation radiation area that the single cooling fan assembly can handle is expanded, thereby improving the integration of the cooling fan assembly and the cooking equipment.

[0023] 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 implementation.

[0024] 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.

[0025] In one possible implementation of the above-mentioned integrated cooking device, the cooking body includes at least one cooking chamber, and the at least one air inlet includes a third air inlet, through which gas in the cooking chamber can enter the heat dissipation box.

[0026] 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.

[0027] In one possible implementation, the first / second air inlet can be in continuous communication with the heat dissipation duct; and / or the second air inlet can be in communication with or not in communication with the heat dissipation duct depending on the pressure inside the cooking cavity.

[0028] 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.

[0029] In one possible implementation of the above-mentioned integrated cooking device, the heat dissipation box includes an air outlet and a first heat dissipation chamber and a second heat dissipation chamber that are connected to each other, wherein the first air inlet and the second air inlet are respectively disposed at positions of the heat dissipation box corresponding to the first heat dissipation chamber and the second heat dissipation chamber; and / or the air outlet is directly connected to the first heat dissipation chamber and / or the second heat dissipation chamber.

[0030] This configuration allows for effective heat dissipation of the equipment through a dual-air intake system.

[0031] In one possible implementation, the heat dissipation box includes a box body, a first cover, and a second cover, wherein the box body and the first cover form the first heat dissipation chamber, and the box body and the second cover form the second heat dissipation chamber.

[0032] In one possible implementation, at least a portion of the cooling fan of the cooling fan assembly is housed within the first cooling chamber and / or the second cooling chamber. This configuration provides possible installation methods for the cooling fan. If the fan is located in both cooling chambers simultaneously, the two chambers can be connected by the installation of the cooling fan; however, if the fan is located in only one chamber, a connecting structure is needed to connect the two chambers. Alternatively, in addition to being located in two cooling chambers, the fan may also have a portion extending out of the cooling fan housing.

[0033] In one possible implementation of the above-mentioned integrated cooking device, the cooking body includes a door assembly disposed in the cooking chamber, and the first heat dissipation duct includes an air inlet side, through which heat from the door assembly can enter the first heat dissipation duct.

[0034] This configuration allows for a certain degree of cooling of the door components through the first heat dissipation duct.

[0035] It is understood that those skilled in the art can determine, based on actual needs, how to ensure that heat from the door assembly can enter the heat dissipation duct via the air inlet side. For example, the air inlet side can be positioned near the door assembly, or the air inlet side can be aligned with the heat dissipation vents on the door assembly to at least a certain extent. It should be noted that the air inlet side here corresponds to the first air inlet side in the specific embodiment.

[0036] In one possible implementation of the aforementioned integrated cooking device, the exhaust direction of the air outlet of the cooling fan assembly is approximately vertical.

[0037] This configuration effectively enhances the user experience through vertical exhaust. The term "approximately vertical" here should be understood as follows: the orientation of the air outlet (which could be an extension of its axis) and / or the airflow direction of the gas exhausted through the 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. Attached Figure Description

[0071] 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 unit disposed above the steam oven (wherein the steam oven has a dual-cavity structure and the cooktop unit includes two cooktops), 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 make flexible adjustments, such as replacing the steam oven with a steam-baking-frying unit, adjusting the relative positions between the two chambers (e.g., left-right, up-down, etc.), and flexibly arranging the number and functions of the chambers, such as including one steaming chamber, one baking chamber, one steam-baking chamber, or one steaming chamber with two baking chambers.

[0072] 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.

[0073] 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.

[0074] 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, well-known items such as stoves and the principles of steaming / baking functional modules are not described in detail in order to highlight the main points of this application.

[0075] The following will refer to the appendix. Figures 1 to 19 The integrated embedded cooking device of this application is described in at least a portion thereof.

[0076] 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.

[0077] In one possible implementation, the integrated built-in cooking equipment 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 built-in installation method. This effectively saves installation space and better integrates with the kitchen's decorative style and ambiance. For example, a fully built-in installation is adopted, meaning the cooktop surface of the cooktop unit is roughly flush with other parts (the countertop of the cabinet), while the steam oven is located below the cooktop surface (e.g., open installation or housed in a lower cabinet). The steam oven mainly includes a cooking body 1, a first cooking unit corresponding to the steaming function (e.g., a steaming function cooking unit 2), a second cooking unit corresponding to the baking function (including pure baking and baking functions involving steaming) (e.g., a baking function 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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 (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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] In general, to ensure the performance of integrated cooking appliances, 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 integrated cooking appliances. While integrated steaming and baking units can better meet user needs—for example, allowing simultaneous steaming and baking using dual-cavity operation—the different functional units all involve heat sources during operation. Therefore, when multiple modules are running, these heat sources may interact and overlap, potentially leading to poor heat dissipation.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] In one possible implementation, the cooling 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 box, and the second cooling air inlet is located on the rear side of the cooling box.

[0096] 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.

[0097] 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).

[0098] 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).

[0099] 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.

[0100] It can be seen that 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 built-in 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 directly integrated built-in cooking device.

[0101] 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.

[0102] 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).

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] In one possible implementation, the integrated built-in 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 heat dissipation and exhaust structure can be a separately added structure or a structure integrated with the components of the integrated built-in cooking appliance. For example, the heat dissipation and exhaust structure can be a heat dissipation exhaust port, an upwardly extending heat dissipation exhaust pipe connected to the heat dissipation exhaust port, or a structure connected to the upper cooktop unit. Taking the exhaust pipe as an example, its downstream side may be connected to the indoor space, directly connected to the outdoor environment, or connected to the outdoor environment via a pipe (such as the duct of a range hood).

[0109] Reference Figure 19 In this example, the integrated cooking appliance has a cooktop unit 200 located above the steam oven 100. The heat dissipation vent of the steam oven's fan assembly can be positioned above the heat dissipation box, connecting to the cooktop surface and thus switching the heat exhaust from front to top. A range hood 300 is typically installed above the cooktop unit (e.g., on the top or side), effectively removing the exhaust heat-laden air and 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.

[0110] 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.

[0111] 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 the room. Of course, the cooking medium from both chambers also carries heat; therefore, this method also prevents the room from overheating.

[0112] 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.).

[0113] 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.

[0114] 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, if the drainage structure is located near the bottom of the cooling fan box, the 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.

[0115] 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.).

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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).

[0120] 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.

[0121] 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.

[0122] 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.

[0123] In one possible implementation, the integrated built-in 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, and two cooktops 7 are mounted on the two mounting positions. 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.

[0124] 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.

[0125] 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.

[0126] In one possible implementation, both the second air outlet side of the second heat dissipation duct and the air outlet of the heat dissipation fan assembly are located near the rear of the cooktop unit, and both need to exhaust gas into the external environment. Therefore, in this example, a shared exhaust structure is provided on the cooktop unit.

[0127] 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.

[0128] 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.

[0129] In one possible implementation, the cooktop shell 6 includes a bottom shell 601 and a cooktop surface (such as cooktop glass, typically the uppermost layer of which is mounted on the bottom shell) 602. The cooktop surface has an exhaust area 61 as a shared exhaust structure. This exhaust area can be an open structure or equipped with exhaust holes, exhaust mesh, etc. A range hood positioned on the side or top of the cooktop can promptly extract the gas delivered to the exhaust area 61. In this example, an exhaust cover 611 with an exhaust mesh (such as a spider web structure) or other connecting structure is provided at the exhaust area of ​​the cooktop surface (such as the cooktop glass). This serves to isolate foreign objects and reduce airflow loss. A sealing structure, such as a sealing ring, is provided between the exhaust cover and the cooktop glass. This sealing structure prevents liquid from the cooktop glass from entering the cooktop shell and also prevents poor sealing of the air duct path due to deformation of the injection-molded parts. In this embodiment, three types of heat-carrying gases can be discharged through the exhaust net: one is heat-carrying gas from the first heat dissipation duct (mainly used to cool the door assembly and the heat-generating components on the top of the steam oven), one is cooking medium from the first / second cooking chamber (mainly used to relieve pressure and exhaust gas to ensure the cooking reliability of the steam oven), and one is heat-carrying gas from the second heat dissipation duct (mainly used to cool the heat-generating components inside the cooktop unit).

[0130] 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 the air outlet side of the second heat dissipation fan, an exhaust connection assembly 62 can be provided near the exhaust area. The exhaust connection assembly 62 mainly includes an exhaust connection body 621. The exhaust connection body is connected to the air outlet of the first heat dissipation fan to collect the heat-carrying medium from the cooking unit. On the other hand, it is connected to the exhaust area 61 on the cooktop so as to discharge the collected heat-carrying medium in a timely manner.

[0131] In one possible implementation, the bottom of the exhaust connection body 621 is provided with a ring-shaped magnetic connection component 622 (such as a permanent magnet). The magnetic connection component 622 can be attracted to the sheet metal of the steam oven corresponding to the heat dissipation vent. The magnetic connection component can play a certain counterweight role to facilitate alignment during the assembly process. On this basis, it can also prevent air leakage through circumferential tight connection, thereby playing a sealing role.

[0132] In this example, the bottom shell 601 of the cooktop has an opening at a position corresponding to the exhaust area. The upper part of the exhaust connection body 621 can be fixed to the bottom shell at the position corresponding to the opening. As in this example, after the upper part of the exhaust connection body 621 is pressed against the bottom shell at the position corresponding to the opening by a pressure plate, the pressure plate, the exhaust connection body, and the bottom shell are fixedly connected by fasteners such as screws. Obviously, the fixation based on the pressure plate is only an exemplary description. Those skilled in the art can use other reasonable methods to fix the exhaust connection body to the cooktop unit according to actual needs, such as snap-fit, direct screw connection, etc.

[0133] For integrated cooking appliances that include a cooktop and a steam oven, a common heat dissipation solution on the market involves installing a centrifugal fan inside the cooktop housing. The lower end of the centrifugal fan is left open to connect with the steam oven's cooling system. This allows a single fan to simultaneously meet the cooling needs of both the cooktop and the steam oven. Additionally, a flexible hose or other connecting structure can be used to connect to the steam oven's wastewater box for condensate return. However, this solution lacks the ability to control the airflow between the two components (the cooktop's internal airflow and the steam oven's cooling ducts). It relies on passive distribution through negative pressure, which limits its effectiveness in meeting cooling requirements. Furthermore, the inability to create numerous ventilation holes at the front of the cooktop housing (as this would reduce the internal negative pressure of the cooktop, hindering the centrifugal fan's ability to effectively absorb heat from the steam oven and impacting overall cooling) negatively affects the cooling performance of the cooktop unit. Furthermore, the installation of the centrifugal fan requires the manual connection of two flexible hoses between the cooktop unit and the steam oven, making installation inconvenient. Additionally, this heat dissipation solution suffers from poor ability to isolate and collect foreign objects.

[0134] In contrast, in the preferred embodiment of this application, parallel cooling is achieved using dual fans (a centrifugal fan corresponding to the steam oven and a cross-flow fan corresponding to the cooktop unit). Since the two flow fields do not interfere with each other (except near the exhaust area; however, the gas in the exhaust area can be promptly removed by a range hood located in the cooktop unit, so even if interference occurs in this area, it has virtually no impact on the overall cooling performance), the fans can be flexibly replaced, their operating parameters adjusted, and the structural parameters of the flow field adjusted according to actual needs. This effectively avoids the problem of passively distributing cooling capacity to the cooktop unit and the steam oven only through negative pressure. Similarly, because the two flow fields do not interfere with each other, more ventilation holes can be opened at the front of the cooktop shell, allowing for sufficient cooling of the cooktop unit by drawing in air (at low temperatures) from the front of the cooktop. The cooktop unit and steam oven can be connected by directly inserting the exhaust connection structure into the cooling vent, making installation convenient and ensuring high connection precision. By combining the exhaust cover and the collection box, foreign objects can be doubly isolated, effectively preventing them from falling in and allowing for easy removal of the collected objects.

[0135] As can be seen, in the preferred embodiment of this application, by arranging the cooling fan assembly on 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 built-in cooking device can be adequately cooled in one location through dual air intake. 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 on the back of the cooking body can not only cool the door assembly and related structures on 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 (heat dissipation 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 unit, the heat dissipation gases from the steam oven and cooktop unit, 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), thus improving the user experience. By using an exhaust connection assembly to connect the cooking unit and the cooktop unit, and setting the connection between the exhaust connection assembly and the cooking unit as a removable magnetic adsorption, installation is convenient and the sealing performance of the exhaust path is ensured.

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.
