Description

Technical Field

[0001] This application relates to the technical field of kitchen appliances, and particularly to an integrated cooking device. The integrated cooking device including a cooling fan assembly in this application is more suitable for full-embedded / flush-embedded installation. Background Art

[0002] There is a certain scale of user demand for cooking ingredients by steaming and roasting. Among them, the cooking principle of steaming is to continuously supply high-temperature steam to the inner container where the ingredients to be cooked are located, and thus the cooking of the ingredients can be completed by pure steaming. The cooking principle of roasting is to continuously supply circulating hot air flow to the inner container where the ingredients to be cooked are located, and thus the cooking of the ingredients can be completed by hot air roasting. Correspondingly, the most basic product forms of kitchen appliances are: using a steam oven to cook ingredients by steaming, and using an oven to cook ingredients by roasting. With the refined development of kitchen appliances, there has emerged a way to cook ingredients by combining steaming and roasting (such as the tender roasting mode, etc.). In this way, in the oven, it is necessary to add components that can generate steam (the cooking medium corresponding to the steaming function), such as an evaporation pan, and configure corresponding steam delivery pipelines, control logics, etc. for the components. Since there is a certain intersection (steam) in the cooking media of the two, there has appeared an integrated steam and roast oven that simultaneously includes the steaming function and the roasting function (including roasting and steam-roasting). In addition, considering the limited space in the kitchen where the cooking device is located, users have proposed the idea of installing more functional kitchen appliances in the limited space as much as possible. Therefore, an integrated steam and roast oven with a certain degree of integration can also meet this demand of users. In addition, to adapt to the relatively common embedded installation currently, there have also appeared integrated steam, roast and fry ovens, combined devices of an integrated steam and roast oven and a cooking appliance unit such as a gas stove, etc.

[0003] Taking the combined device of a steam oven and gas stove and other cooking units as an example, for the steam oven, the cooking media for the two cooking methods of steaming and roasting are steam and hot air flow (which may also contain steam) respectively. Therefore, there will inevitably be a heat dissipation requirement during the cooking process. For example, heat dissipation is required for the door body assembly (such as the steam and hot air flow thermally radiate the door body assembly, causing its temperature to rise. Since the door body assembly is close to the user, considering the use safety, heat dissipation for the door body assembly is required). In addition, there are also relevant structures and components that need to be dissipated heat, such as those set at the top, side, etc. positions inside the cooking device. Taking the components as an example, the working reliability of the components is affected by temperature (for example, on the one hand, the components themselves are heat sources, so they will heat up due to being in a long-term working state; on the other hand, the steam and hot air flow thermally radiate the top of the inner container where the components are located, etc., which will also cause their temperature to rise). For the gas stove, the part close to the cooking unit belongs to the thermal radiation area, and the components inside it that need to be dissipated heat are also heat-generating components themselves. Since the cooking device has multiple functions, the heat to be dissipated / the medium carrying heat to be discharged will increase. Since the cooking device itself has a certain degree of integration, various heats may be superimposed, interfered with, etc. In this case, on the premise of being able to effectively dissipate heat from the cooking device and timely discharge the gas / cooking medium carrying heat generated by heat dissipation, how to improve the integration of the device as much as possible has quite a lot of room for improvement. Summary of the Invention

[0004] This application aims to at least partly solve the above technical problems and / or at least partly solve some of the above technical problems. Specifically, how to improve the integration of the device as much as possible while dissipating heat from the integrated cooking device including the cooking unit and timely discharging the gas carrying heat.

[0005] In view of this, this application provides an integrated cooking device, which includes a cooking unit. The cooking unit includes: a stove shell, and an exhaust area that can communicate with the external environment is provided on the stove shell or at a position close to the stove shell; and a cooking unit heat dissipation part, which includes a cooking unit heat dissipation air duct, and the cooking unit heat dissipation air duct is arranged inside the stove shell; wherein, the gas in the cooking unit heat dissipation air duct can be discharged through the exhaust area; the device also includes a cooking unit, and the cooking unit includes an air outlet, and the gas can reach the exhaust area through the air outlet of the cooking unit and be discharged.

[0006] With such a configuration, it is possible to seek to discharge the heat-carrying gas generated by heat dissipation in the stove shell through the exhaust area. In addition, by associating with the heat dissipation air outlet of the cooking unit, the exhaust path of the device is integrated, and to a certain extent, the integration degree of the device is improved. It should be noted that the heat dissipation part of the cooking unit, the heat dissipation air duct of the cooking unit, the cooking unit, and the air outlet correspond to the second heat dissipation part, the second heat dissipation air duct, the steam oven, and the heat dissipation air outlet in the specific embodiment.

[0007] For the above integrated cooking device, in a possible embodiment, the heat dissipation part of the cooking unit includes a heat dissipation fan of the cooking unit. The air inlet of the heat dissipation fan of the cooking unit is communicated with the environment inside the stove shell, and the air outlet of the heat dissipation fan of the cooking unit is communicated with the air inlet side of the heat dissipation air duct of the cooking unit.

[0008] With such a configuration, it is possible to seek to dissipate heat from components such as components in the environment inside the stove shell through the heat dissipation fan of the cooking unit. It should be noted that the heat dissipation fan of the cooking unit here corresponds to the second heat dissipation fan in the specific embodiment.

[0009] For the above integrated cooking device, in a possible embodiment, an exhaust connection structure is provided between the air outlet of the cooking unit and the exhaust area.

[0010] With such a configuration, it is possible to seek to ensure that the heat-carrying gas from the cooking unit can be reliably discharged to the external environment through the exhaust area.

[0011] For the above integrated cooking device, in a possible embodiment, the stove shell includes a stove top, and the exhaust area is provided on the stove top of the stove shell.

[0012] With such a configuration, a possible way for the exhaust area to form the heat dissipation unit of the cooking unit is given. For example, the exhaust area is arranged at a position on the stove top far from the operator to ensure the use safety of the device. Exemplarily, the exhaust area can be arranged at the middle of the rear side, the position near the corner of the rear side, both sides, or the front side where the operator is not easily accessible, etc.

[0013] For the above integrated cooking device, in a possible embodiment, the cooking unit includes: a cooking main body, which includes at least one cooking chamber; a cooking unit heat dissipation air duct; and a heat dissipation fan assembly, which includes an air outlet and at least one air inlet. The air inlets of the heat dissipation fan assembly include a first air inlet and a second air inlet. Among them, the gas in the cooking unit heat dissipation air duct can reach the heat dissipation fan assembly through the air outlet side of the cooking unit heat dissipation air duct and the first air inlet and be discharged through the air outlet of the heat dissipation fan assembly; among them, the second air inlet is communicated with the installation space of the cooking main body.

[0014] For the above integrated cooking device, in a possible implementation manner, the air inlet of the heat dissipation fan assembly includes a third air inlet, wherein the gas in the cooking chamber can reach the heat dissipation fan assembly via the third air inlet and be discharged through the air outlet.

[0015] With such a configuration, it is possible to collect the gas from the first / second / third air inlets through the same heat dissipation fan assembly and discharge it centrally, improving the integration degree of the cooking device. Specifically, the heat dissipation media from different positions of the cooking unit are collected through the first / second air inlets and further discharged, so as to effectively cool related connection structures, components and other parts. The gas from the cooking chamber is collected through the third air inlet and further discharged, thus ensuring the reliability of the cooking device. It should be noted that the heat dissipation air duct of the cooking unit and the first / second / third air inlets correspond to the first heat dissipation air duct, the first / second heat dissipation air inlets and the air intake connection structure in the specific implementation manner.

[0016] It should be noted that the installation space of the cooking main body should be understood as follows: the cooking main body includes an outer shell, an installation space is formed inside the shell, and the installation space contains an inner tank forming the cooking chamber, and related structures such as a first heat dissipation air duct, components, and a heat dissipation fan assembly are arranged outside it. There is a certain margin between the installation space and the structures accommodated therein. The second air inlet is mainly used to meet the heat dissipation requirements of the surfaces of the structures accommodated therein and the parts close to the surfaces, such as the installation space in the side, bottom and other directions.

[0017] For the above integrated cooking device, in a possible implementation manner, the heat dissipation fan assembly includes a heat dissipation air box, and the heat dissipation air box includes a first heat dissipation chamber and a second heat dissipation chamber that communicate with each other. Among them, the first air inlet and the second air inlet are respectively arranged at positions of the heat dissipation air box corresponding to the first heat dissipation chamber and the second heat dissipation chamber; and / or the air outlet is directly communicated with the first heat dissipation chamber and / or the second heat dissipation chamber.

[0018] With such a configuration, it is possible to effectively dissipate the heat of the device by means of double air inlet. It should be noted that the second air inlet here corresponds to the second heat dissipation air inlet in the specific implementation manner.

[0019] In a possible implementation manner, the heat dissipation air box includes an air box main body, a first cover body and a second cover body. Among them, the air box main body and the first cover body form the first heat dissipation chamber, and the air box main body and the second cover body form the second heat dissipation chamber. With such a configuration, a possible structural form of the air box main body is given.

[0020] In a possible implementation, the heat dissipation fan assembly includes a heat dissipation fan, and at least a part of the heat dissipation fan is accommodated in the first heat dissipation chamber and / or the second heat dissipation chamber.

[0021] With such a configuration, a possible installation method of the heat dissipation fan is given. For example, in the case of being in two heat dissipation chambers at the same time, the two heat dissipation chambers can be connected due to the installation of the heat dissipation fan. In the case of only being in one of the chambers, the connection between the two chambers needs to be realized by setting a connection structure. For example, in addition to being in two heat dissipation chambers, there can also be a part of the chamber that extends out of the heat dissipation air box.

[0022] For the above integrated cooking device, in a possible implementation, the cooking main body includes a door body assembly disposed in the cooking chamber, and the heat from the door body assembly can enter the cooking unit heat dissipation air duct through the air inlet side of the cooking unit heat dissipation air duct.

[0023] With such a configuration, it is possible to seek to cool the door body assembly to a certain extent through the cooking unit heat dissipation air duct.

[0024] It can be understood that those skilled in the art can determine the implementation manner in which the heat from the door body assembly can enter the cooking unit heat dissipation air duct through the air inlet side according to actual needs. For example, the air inlet side can be set near the door body assembly, and the air inlet side is at least partially aligned with the heat dissipation opening on the door body assembly, etc. It should be noted that the air inlet side here corresponds to the first air inlet side in the specific implementation manner.

[0025] For the above integrated cooking device, in a possible implementation, there is an included angle between the exhaust direction corresponding to the air outlet of the cooking unit and the horizontal plane.

[0026] With such a configuration, it is possible to seek to at least avoid to a certain extent the problem of the user experience decline caused by the air outlet directly blowing on the user.

[0027] For the above integrated cooking device, in a possible implementation, the exhaust direction corresponding to the air outlet of the cooking unit is substantially the vertical direction.

[0028] With such a configuration, it is possible to seek to effectively improve the user experience by vertical exhaust. Here, the substantially vertical direction should be understood as: the setting direction of the air outlet (which can be the extension direction of its axis) and / or the air flow direction of the gas discharged through the air outlet can be considered to be substantially vertical. For example, it can be: having a small included angle with the vertical direction (such as an included angle less than 15°), or a non-straight line that is substantially the same as the vertical direction; etc. Description of the Drawings

[0073] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present application and are not intended to limit the protection scope of the present application. For example, although this embodiment is introduced for an integrated cooking device in combination with a steam and roast integrated machine (including a steam function and a roast function (including hot air roast and steam roast)) and a cooktop assembly (in this example, the cooktop assembly includes two cooktop units) all arranged above the double-chamber steam and roast integrated machine, and the steam and roast integrated machine is a double-chamber structure, this is not intended to limit the protection scope of the present application. Without departing from the principle of the present application, those skilled in the art can apply the present application to other application scenarios, such as a steam, roast, and fry integrated machine, a steam and roast integrated machine, etc. In addition, the double-chamber structure including a steam chamber and a roast chamber in the integrated cooking device is only an exemplary description. Those skilled in the art can adjust the relative positions between the two chambers (such as left and right, up and down, etc.), and can flexibly arrange the number and functions of the chambers, such as the chambers including one steam, one roast, one steam and roast, one steam and two roasts, etc.

[0074] It should be noted that in the description of the present application, the terms indicating directions or position relationships such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or position relationships shown in the drawings. This is only for convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0075] In addition, it should also be noted that in the description of the present application, unless otherwise clearly specified and limited, the terms "installation", "setting", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can also be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0076] In addition, to better illustrate the present application, numerous specific details are given in the following specific embodiments. Those skilled in the art should understand that the present application can also be implemented without some specific details. In some instances, the principles of cooktops such as gas stoves well-known to those skilled in the art and the steam / roast functions are not described in detail in order to highlight the main idea of the present application.

[0077] The integrated cooking device of the present application will be described below with reference to at least a part of Figures 1 to 15 the accompanying drawings.

[0078] If the double cavity in the steam and convection oven adopts the independent steam and convection mode, it is necessary to configure steam generating devices such as evaporation trays for both the first cooking cavity corresponding to the steam function cooking unit and the second cooking cavity corresponding to the convection function cooking unit. Among them, the structural form of adding an evaporation tray to the second cooking cavity will increase the cost of the equipment and will also increase the complexity of the water circuit corresponding to the steam supply to a certain extent. In addition, due to the limited water storage capacity of the evaporation tray and the influence of various factors such as its heating principle and water replenishment logic, during the operation of the steam and convection oven, problems such as yellowing due to dry burning, water overflow due to excessive water replenishment, and scale formation in the evaporation tray will inevitably occur. In this way, in the case of problems, it is necessary to perform maintenance operations on the two sets of systems for the double cavity, increasing the maintenance cost. In addition, the configuration of the two evaporation trays and the corresponding pipelines will also increase the volume of the steam and convection oven. Therefore, in this application, first configure the same steam generating device (such as a steam generator) for the first cooking cavity and the second cooking cavity, that is, use the same steam generating device as the steam source for the double cavity. On this basis, by configuring the corresponding pipelines, logic, etc. for the double cavity, the evaporation supply for the double cavity can be realized. In this way, there is still a certain room for improvement in related links such as the steam pipeline.

[0079] In a possible implementation, the integrated cooking device mainly includes a steam and convection oven 100 and a cooking unit 200. For example, the cooking unit 200 is disposed above the steam and convection oven 100. It can be installed in the kitchen in an embedded manner, which can effectively save installation space and better integrate with the decoration style and tone of the kitchen. Exemplarily, a full-embedded installation is adopted, that is, the cooking surface of the cooking unit is substantially flush with other parts (the countertop), and the steam and convection oven is located in the lower cabinet. Among them, the steam and convection oven mainly includes a cooking main body 1, a first cooking unit corresponding to the steaming function (which can be called the steaming function cooking unit 2), a second cooking unit corresponding to the baking function (including the pure baking function and the baking function with the participation of the steaming function) (which can be called the baking function cooking unit 3), and a steam part 4 that supplies the cooking medium of steam to both the first cooking unit and the second cooking unit. In this example, the cooking main body forms two cooking chambers for holding the ingredients to be cooked. That is, in this example, the steam and convection oven has a double-chamber structure. For example, the cooking main body 1 includes two inner liners corresponding to the first cooking unit and the second cooking unit, and the two inner liners respectively form a first cooking chamber 11 and a second cooking chamber 12 corresponding to the first cooking unit and the second cooking unit. Shelves can be provided inside the inner liner, and the ingredients to be cooked can be directly placed on the shelves or in utensils (such as plates) placed on the shelves. Or a placing structure such as a concave structure or a rotatable plate is provided on the inner side of the bottom of the inner liner. The ingredients to be cooked can be directly placed on the placing structure, or after the ingredients to be cooked are placed in a utensil, the bottom of the utensil can be placed at a position corresponding to the placing structure. Since the realization of the steaming and baking functions is closely related to the temperature of the cooking medium, heating components such as heating pipes can be provided at positions such as the inner side of the top, the inner side of the side, and the inner side of the bottom of the inner liner, so that in case of need, the cooking medium in the cooking chamber (the hot air flow circulating in the second cooking chamber and / or the steam diffused in the first / second cooking chamber) can be mainly heated or assisted / supplemented heated.

[0080] In a possible implementation, the steam unit 4 mainly includes a steam generating device 41 and a first steam pipeline and a second steam pipeline communicating with the first cooking chamber and the second cooking chamber. For example, the steam generating device can be a steam pan, a steam generator, etc. For example, the steam generator is arranged on the back of the cooking main body (at a position in the installation space of the cooking main body close to the first cooking chamber) through an installation structure such as a bracket 411 (such as a Z-shaped bracket). Among them, the steam generating device mainly includes a steam generating device body and a water storage container (such as a water tank, etc.). The steam generating device body forms a steam generating chamber and is configured with steam generating heating components such as heating tubes. The water tank is mainly used to supply water (steam generating agent) for generating steam to the steam generating chamber. For example, water is pumped into the steam generating chamber through a water pump 42. The water in the steam generating chamber is heated by the heating tube to generate steam as a cooking medium. The steam pipeline 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. Based on this, the food to be cooked can be cooked in a pure steaming manner through a corresponding control program; and / or steam is added to the second cooking chamber where the food to be cooked is located. Based on this, the food to be cooked can be cooked in a steam baking manner or the like through a corresponding control program. The first steam distribution port 431 corresponding to the first evaporation pipeline and the second steam distribution port 432 corresponding to the second evaporation pipeline, and the two steam distribution ports are preferably arranged at positions close to the two side walls of the cooking main body to minimize the probability of steam turbulence occurring between different working modes.

[0081] In a possible implementation, the steam unit 4 includes a water collecting box 44. The water collecting box is mainly used to collect, for example, accumulated water during the cooking process, high-humidity water vapor in the first cooking chamber, high-temperature and high-humidity gas in the second cooking inner chamber, and the condensed accumulated water described below. For example, a drainage pump can be configured for the collecting box. For example, the collected water can be drained into a waste water box configured for the whole machine through the drainage pump. For example, the waste water box can be regularly cleaned and the accumulated water can be poured out. In this example, the water collecting 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 select the specific form of the installation structure according to actual needs, such as installing the two in two separated structures, etc.

[0082] In this example, a chamber is provided at the bottom of the cooking main body, and both the water tank and the waste water box are accommodated in the chamber at the bottom of the cooking main body.

[0083] Based on the heat dissipation fan assembly described below, in addition to the first heat dissipation air duct at the top, a vertical heat dissipation air duct (the area between the back regions of the two cooking units and the back of the housing of the cooking main body) is constructed on the back side of the cooking main body. Compared with the second cooking unit, since the heat at the back of the first cooking unit is relatively low, components with heat dissipation requirements such as the steam generating device and the electronic control board 16 can be arranged at a position on the back side of the cooking main body close to the first cooking unit. In addition, for the air box main body, the front cover body, and the back cover body of the heat dissipation air box, plastic parts with certain temperature resistance requirements can be selected. The process of the heat dissipation fan assembly can be simplified by injection molding.

[0084] In this example, the electronic control board is located below the heat dissipation fan assembly and on the side (in the width direction) of the back away from the cooking unit corresponding to the baking function. The steam generator is located below the heat dissipation fan assembly and at a position on the steaming function cooking unit close to the baking function cooking unit (because steam needs to be supplied to the baking function cooking unit simultaneously). The water collection box is roughly arranged below the electronic control board, and the water pump is roughly arranged below the steam generator. The cooking main body forms two chambers at the positions corresponding to the water collection box and the steam generator, and a waste water box and a clean water box are respectively accommodated in the two chambers. Obviously, those skilled in the art can appropriately adjust the installation positions of the components and the relative positions between the components, such as arranging the steam generator, the water collection box, the water pump, etc. in other integrated ways, or arranging a part of the electronic control board at the top.

[0085] In a possible implementation manner, the baking function cooking unit 3 generally includes a fan cover assembly 31, and the fan cover assembly is mainly used to provide a circulating hot air flow into the second cooking chamber 12. For example, the fan cover assembly mainly includes a fan such as a centrifugal fan 311 (which can be called a temperature - equalizing fan) and heating components such as heating coils. The temperature - equalizing fan is mainly used to keep the temperature of the hot air flow in the second cooking chamber as low and uniform as possible. To reduce the working temperature of the temperature - equalizing fan, an insulating structure such as heat - insulating cotton can be arranged between the temperature - equalizing fan and the second cooking chamber to effectively isolate the continuous heat radiation from the second cooking chamber to the area of the temperature - equalizing fan. In this example, the fan cover assembly includes a fan cover 312, and the cooking main body 1 includes a back plate. In this example, the cooking main body 1 includes a back cover shell 14, and the back cover shell includes a back plate 141 and two side plates 142 respectively extending forward from both sides of the back plate. A hot air chamber is formed between the back plate 141 and the fan cover. A centrifugal fan is arranged in the hot air chamber, and heating components such as heating coils can be arranged in the hot air chamber or at other positions close to the hot air chamber. Taking the heating component as a heating coil as an example, the heating coil can be arranged in the hot air chamber, and the centrifugal fan can be arranged in the area surrounded by the heating coil.

[0086] Obviously, those skilled in the art can determine the structural form of the blower cover / back plate, its installation position relative to the cooking main body, the connection method between the two, etc. according to actual needs. Exemplarily, the back plate is a separate structure, etc. In this example, the cooking main body is provided with the aforementioned back plate on the side away from the user (such as the rear side). Obviously, in addition to the rear side, the back plate can also be provided on other side parts (such as the left side, the right side). The blower cover and the back plate can be connected to each other by means of snap connection, screw connection, welding, etc., and the two can also be integrally formed.

[0087] In addition, the combination of the back plate and the blower cover is only an exemplary description of forming the hot air chamber. Those skilled in the art can determine the specific form of the hot air chamber according to actual needs. Exemplarily, a constraint structure is provided on the blower cover to allow the aforementioned centrifugal blower to be installed in the hot air chamber and removed from the hot air chamber, etc. For example, the constraint structure includes a plurality of limiting pieces arranged circumferentially along the hot air chamber and pivotally openable relative to the blower cover. In this way, it can be considered that the blower cover and the constraint structure form the hot air chamber, or it can also be considered that the back plate and the blower cover provided with the constraint structure form the hot air chamber.

[0088] It should be noted that the so-called hot air chamber is not absolutely a complete chamber, but should be understood as an installation position for accommodating the centrifugal blower and the heating coil. Therefore, those skilled in the art can determine the structural form, connection situation, etc. of the hot air chamber according to actual needs. Exemplarily, the centrifugal blower and the heating coil can be arranged in the same chamber or placed in two connected chambers respectively, etc. The hot air chamber can achieve its connection state with the second cooking chamber through a plurality of communication holes, or can also achieve its connection with the second cooking chamber by setting a certain part as an open structure.

[0089] For example, the blower cover is provided with an air return port near the centrifugal blower, and the blower cover is also provided with an air supply port, such as the air supply port is arranged approximately circumferentially around the air return port or a partial position of the circumference. For example, the centrifugal blower includes a motor and a fan, the motor rotates to drive the fan to rotate at a position facing the air return port, and the rotation of the fan can introduce the air in the inner container into the hot air chamber through the air return port. In this example, the heating coil is arranged at a position corresponding to the air return port in the hot air chamber, and the fan is arranged in the area circled by the heating coil. In this way, under the action of the blower, the air in the inner container is sucked into the hot air chamber through the air return port, and then heated by the heating pipe to be converted into a hot air flow carrying heat and serving as a cooking medium. In this way, the hot air flow is thrown to the peripheral air supply port by the blower and thus sent into the inner container again. By circulating in this way, the hot air flow can be continuously emitted to the surface of the food to be cooked, so as to cook the food to be cooked in the way of hot air roasting through a corresponding control program.

[0090] In a possible implementation, the cooking main body 1 is provided with a door assembly on the operation side close to the user (such as the operation side is the side facing the user, usually referred to as the front side), which can be opened (such as pivoted open vertically / horizontally). For example, one door assembly can be configured for each of the two inner liners, or two inner liners share one door assembly (such as the door assembly can be a rigid structure or include two relatively movable door parts), or a shared door assembly (two-layer door) is added after one door assembly is configured for each of the two inner liners. In this example, the door assembly includes a first door assembly 151 and a second door assembly 152 corresponding to the steaming function cooking unit and the baking function cooking unit respectively.

[0091] Under normal circumstances, in order to ensure the performance of the integrated cooking device, the working environment of the door, the power board, and related electrical components with temperature requirements (such as those arranged at the top, back, etc. of the cooking main body) needs to be within a certain temperature range. After combining the steaming function cooking unit, the baking function cooking unit, and the cooking stove assembly, more heat may be generated in the limited space. As a result, more sufficient heat dissipation is required for the integrated cooking device. Although the integrated steaming function cooking unit and baking function cooking unit can better meet the cooking needs of users, for example, users can achieve simultaneous steaming and baking cooking in the way of double-chamber synchronous operation. However, since each unit with different functions involves a heat source during operation, when multiple functional modules are running, there may be mutual influences such as cross and superposition between different heat sources, which will lead to poor heat dissipation of the device.

[0092] In a possible implementation, the integrated cooking device includes a first heat dissipation part 5 arranged in the steam and bake all-in-one machine. The first heat dissipation part includes a first heat dissipation air duct 51 and a heat dissipation fan assembly 52. In this example, the first heat dissipation air duct is arranged at the top of the cooking main body, and the heat dissipation fan assembly is mainly used to suck air through the first heat dissipation air duct to a position corresponding to the heat dissipation fan assembly and then discharge it, so as to dissipate heat from the power board, electrical components, etc. as described above to ensure their operation reliability.

[0093] Under normal circumstances, the heat dissipation fan assembly is a cross-flow fan arranged at the top of the cooking main body and communicating with the first heat dissipation air duct. However, the top-mounted structure will to some extent affect the expansion space at the top of the inner liner. For example, it will significantly increase the size of the device in the height direction and limit the increased space of the inner liner volume in the height direction. Therefore, in this application, the heat dissipation fan assembly is arranged at the side of the cooking main body.

[0094] In this example, the cooling fan assembly 52 is disposed on the back side of the cooking main body. More specifically, in this example, the cooling fan assembly is disposed at a position on the back side of the cooking main body corresponding to the steaming function cooking unit. In this way, the size of the device in the height direction is reduced, making the device more compact, thereby improving the integration degree of the device to a certain extent.

[0095] In a possible implementation manner, the cooling fan assembly 52 mainly includes a cooling air box 521 and a first cooling fan 522. For example, if the first cooling fan is a centrifugal fan, the cooling air box 521 mainly includes an air box main body 5211, a first cover body 5212 (which can be called a front cover body for example) disposed on the front side of the air box main body, and a second cover body 5213 (which can be called a rear cover body for example) disposed on the rear side of the air box main body. A first cooling chamber 5214 (which can be called a front cooling chamber for example) is defined between the air box main body and the front cover body, and a second cooling chamber 5215 (which can be called a rear cooling chamber for example) is defined between the air box main body and the rear cover body. The first cooling chamber 5214 and the second cooling chamber 5215 communicate with each other, and the first cooling fan 522 is installed in the cooling air box. In this example, a part of the first cooling fan 52 is in the front cooling chamber and a part is in the rear cooling chamber. Therefore, the two cooling chambers can communicate with each other by means of the installation of the first cooling fan. It can also be that the first cooling fan is only in one of the two cooling chambers, and the two cooling chambers communicate with each other through a communication structure such as a communication hole.

[0096] Obviously, the combination of the front and rear cover plates and the air box main body is only an exemplary composition form of the cooling air box. For example, the front cover plate can be replaced by the rear wall of the inner container or the two (the front cover plate and the rear wall of the inner container) can be integrally formed, that is, the cooling air box and the rear wall of the inner container form a cooling chamber. In addition, those skilled in the art can determine the structural form, covering area, and connection method between the front / rear cover plates and the air box main body according to actual needs.

[0097] In a possible implementation manner, the cooling air box is provided with a first cooling air inlet 5216 at a position communicating with the first cooling chamber, and a second cooling air inlet 5217 and a cooling air outlet 5218 are provided at a position communicating with the second cooling chamber. The first air outlet side of the first cooling air duct can be connected to the first cooling air inlet, and the second cooling air inlet can be directly connected to the back side space of the cooking main body of the integrated cooking device. In this example, the first cooling air inlet and the cooling air outlet are disposed at the top of the cooling air box, and the second cooling air inlet is disposed at the back side of the cooling air box.

[0098] In order to enable the gas to be discharged better through its heat dissipation air outlet 5218, a heat dissipation air outlet guiding structure 5219 is provided at the position of the heat dissipation air box corresponding to the heat dissipation air outlet. The heat dissipation air outlet guiding structure can be an inclined surface, a curved surface, and related combined structures, such as the combination of inclined surfaces, the combination of curved surfaces, the combination of an inclined surface and a curved surface, etc.

[0099] In this way, with the high-speed operation of the centrifugal fan, two negative pressure areas will be formed at the positions corresponding to the first heat dissipation chamber and the second heat dissipation chamber (such as the first negative pressure area / front negative pressure area corresponding to the first heat dissipation chamber and the second negative pressure area / rear negative pressure area corresponding to the second heat dissipation chamber are respectively called).

[0100] For the first negative pressure area among them, under the guidance of the first heat dissipation fan, the air entering the first heat dissipation air duct through the first air inlet side of the first heat dissipation air duct enters the first heat dissipation chamber through the first heat dissipation air inlet and is discharged through the heat dissipation air outlet. The first heat dissipation air inlet and the first air outlet side of the first heat dissipation air duct can be docked through direct connection (such as socket connection), indirect connection through an intermediate pipe section, alignment (such as no connection relationship can be generated), etc.

[0101] The gas in the back space of the cooking main body rises in temperature after cooling the relevant components therein. For the second negative pressure area among them, under the guidance of the first heat dissipation fan, the gas with increased temperature enters the second heat dissipation chamber through the second heat dissipation air inlet and is then discharged through the heat dissipation air outlet.

[0102] It can be seen that through the combination of the (first heat dissipation air inlet of) the heat dissipation fan assembly and the first heat dissipation air duct, the relevant components in the top area of the integrated cooking device can be cooled. By providing a second heat dissipation air inlet for the heat dissipation fan assembly, the relevant components in the back area of the direct integrated cooking device can be cooled.

[0103] Obviously, the structural forms, numbers, installation positions, and corresponding connection methods of the first / second heat dissipation air inlets and the heat dissipation air outlet are only an exemplary description, and those skilled in the art can flexibly adjust them according to actual needs. For example, the heat dissipation air outlet can be directly communicated with both the first / second heat dissipation chambers (in this example, the first heat dissipation air inlet is communicated with the first heat dissipation chamber, the first heat dissipation chamber is communicated with the second heat dissipation chamber, and the second heat dissipation chamber is communicated with the heat dissipation air outlet), etc. The implementation methods of directly communicating the heat dissipation air outlet with both the first / second heat dissipation chambers can include but are not limited to that the heat dissipation air outlet includes two, the air inlet side of the heat dissipation air outlet is respectively communicated with the first / second heat dissipation chambers, the heat dissipation air outlet includes two branch pipes on the upstream side respectively communicated with the first / second heat dissipation chambers and a main pipe on the downstream side respectively communicated with the two branch pipes, etc.

[0104] In a possible implementation, the first heat dissipation duct 51 simultaneously covers the cooking units corresponding to the steaming function and the baking function along the width direction of the device, so that the heat dissipation function of the device can be more fully realized. For example, the first heat dissipation duct may include one or more first heat dissipation ducts. In the case where the first heat dissipation duct includes multiple first heat dissipation ducts, the structural form of the multiple first heat dissipation ducts and their layout on the top can be flexibly adjusted. Exemplarily, a plurality of heat dissipation sub-ducts extend from the first air outlet side of the first heat dissipation duct, and the first air inlet side of each heat dissipation sub-duct is connected to different areas, such as a heat-generating component, the side of the cooking body, another first heat dissipation duct, a non-heat-generating area (i.e., natural wind can be drawn into the first heat dissipation duct), etc.

[0105] In a possible implementation, the first air inlet side 511 of the first heat dissipation duct is located at the front side of the cooking body, such as being arranged at the front door frame of the cooking body, and the first air outlet side 512 is connected to the heat dissipation air inlet of the first heat dissipation duct assembly at the back side. In this way, the first heat dissipation duct spans across the two cooking units in the width direction of the cooking body, and the heat dissipation paths arranged diagonally at the right front and the left rear further increase the length of the first heat dissipation duct, so it is expected that the relevant components can be cooled more fully.

[0106] It should be noted that the diagonal arrangement mentioned here should be understood as after the arrangement direction in the front-to-back direction is roughly determined, the first air inlet side and the first air outlet side are staggered to a certain extent in the left-to-right direction, thereby appropriately lengthening the length of the first heat dissipation duct.

[0107] In a possible implementation, the first air inlet side of the first heat dissipation duct is located in the heat dissipation area (such as the heat dissipation area is provided with a heat dissipation port) of the second door assembly 152 corresponding to the grilling function cooking unit, such as being aligned with the heat dissipation port of the second door assembly to a certain extent or being located near the heat dissipation port. In this way, the heat dissipation fan assembly can share at least a part of the heat dissipation for the second door assembly while dissipating the heat of the heat generating components in the top area.

[0108] It should be noted that the alignment with the heat dissipation area of ​​the second door assembly to at least a certain extent mentioned here should be understood mainly as alignment in terms of orientation. Since the first / second door assemblies for the cooking unit with steaming / baking functions are arranged adjacent to each other, the heat dissipation fan assembly can bear part of the heat dissipation for the first door assembly in addition to the heat dissipation for the second door assembly. Preferably, in order to better dissipate the mechanical energy of the first door assembly, the first heat dissipation duct can be widened at a position close to the first air outlet side so that it is aligned with the heat dissipation area of ​​the first / second door assembly to at least a certain extent, or a connecting hole can be added to the first heat dissipation duct at a position close to the first air outlet side or a connecting section can be extended to introduce heat from the first door assembly 151.

[0109] In addition, under the guidance of arranging a cross-flow fan at the top of the cooking main body, usually the air carrying heat is discharged forward from the gap of the door body assembly. The heat dissipation method in the front row will cause the heat to directly blow on the user (such as the position of the user's legs in this example), thus reducing the user experience.

[0110] In a possible implementation manner, the integrated cooking device includes a discharge structure arranged at an angle with the horizontal direction and capable of discharging the air carrying heat upward. For example, it can enable the air carrying heat to be discharged upward at a large angle with the horizontal direction (such as ≥60°). Exemplarily, it is discharged along a substantially vertical direction. The heat dissipation and exhaust structure therein can be a separately added structure or a structure that collaborates based on the components of the integrated cooking device. For example, the heat dissipation and exhaust structure can be a heat dissipation and exhaust port, a heat dissipation and exhaust pipe extending upward connected to the heat dissipation air outlet, a structure communicating with the cooking unit above, etc. Taking the exhaust pipe as an example, for example, the downstream side of the exhaust pipe can communicate with the indoor space, directly communicate with the outdoor environment, or communicate with the outdoor environment through a pipe capable of communicating with the outdoor environment (such as the pipe of an oil fume extractor).

[0111] In this example, the integrated cooking device is provided with a cooking unit 200 above the steam and convection oven. For example, the heat dissipation air outlet 5212 can be arranged above the heat dissipation air box, and the heat dissipation air outlet is connected to the cooking surface part of the cooking unit, thus switching the front-row heat dissipation to the upper-row heat dissipation. Usually, an oil fume extractor is arranged above (such as the top or side) of the cooking unit, and the discharged air carrying heat can be timely extracted by the oil fume extractor, thereby avoiding the increase in the temperature of the indoor space caused thereby. The connection method between the heat dissipation air outlet and the cooking surface part of the cooking unit can be realized by means of configuring a pipe, adding a communication structure such as a communication hole on the cooking surface part, directly aligning at least a part of the heat dissipation air outlet with the position (cooking opening) on the cooking surface part of the cooking unit where air can be exhausted, etc.

[0112] In a possible implementation manner, the cooking main body is respectively provided with an air outlet communication structure for exhausting air and relieving pressure corresponding to the steam function cooking unit and the baking function cooking unit (such as respectively denoted as the first air outlet communication structure and the second air outlet communication structure, and the first air outlet communication structure and the second air outlet communication structure are respectively connected to the heat dissipation air box, so that under the action of the first heat dissipation fan, the relieved gas is discharged through the aforementioned heat dissipation air outlet. The air outlet communication structure can include one or more communication holes.

[0113] In this example, the first air outlet connection structure and the second air outlet connection structure include a connection hole with a certain radial dimension (it can be understood that the radial dimension of the connection hole is larger than the radial dimension of each single hole in the porous structure (mesh hole)). For example, the first air outlet connection structure and the second air outlet connection structure are respectively arranged at the positions corresponding to the backs of the first / second cooking chambers of the cooking main body, and two air inlet connection structures (such as respectively denoted as the first air inlet connection structure 52111 and the first air inlet connection structure 52112) are arranged at the corresponding positions (close to the walls of the first / second cooking chambers) of the heat dissipation air box. In this way, when the heat dissipation air box is in the working state, the gas discharged from the first / second cooking chambers through the first / second air outlet connection structures can be discharged upward together through the heat dissipation air outlet. For example, the first / second air inlet connection structures can communicate with the aforementioned first heat dissipation chamber and / or the second heat dissipation chamber (in this example, the first / second air inlet connection structures communicate with the positions close to the heat dissipation air outlet of the second heat dissipation chamber). Similarly, the gas discharged upward can be timely sucked away by the range hood at the top / side of the cooking appliance. However, different from the air from the aforementioned first heat dissipation air duct, the air from the first heat dissipation air duct mainly needs to be discharged by re-planning the path because it carries heat, while the gas (cooking medium) in the first / second cooking chambers ensures the cooking quality in the first / second cooking chambers by exhausting and relieving pressure. Since this part of the gas belongs to the cooking medium, especially for the gas in the cooking chamber, it often contains substances such as oil stains, so discharging it in time can ensure the cleanliness of the indoor space. Of course, the cooking media from the two cooking chambers also carry heat, so such a treatment method can also avoid the temperature rise of the indoor space at the same time.

[0114] Obviously, arranging a pair of air outlet connection structures adjacent to each other at the back of the cooking main body is only a preferred implementation method. For example, only one can be arranged at the back of the cooking main body while the other is still arranged at the top (communicating with the first heat dissipation air duct), both air outlet connection structures are arranged at the top, and the two air outlet connection structures are not arranged adjacent to each other (such as one is connected to the back of the heat dissipation air box and the other is connected to the side / top / bottom of the heat dissipation air box, etc.).

[0115] Compared with the current common method of setting a pressure relief port at the top of the inner liner, by arranging the two air outlet connection structures adjacent to each other and respectively docking with the heat dissipation fan assembly, the integration degree of the equipment is improved on the premise of ensuring cooking reliability.

[0116] In addition, for the first cooking chamber and the second cooking chamber during the intervention of steam, since part of the steam will condense during the discharge process of the steam, a drainage structure (such as a drain port, a drain pipe, etc.) 52113 is provided on the heat dissipation bellows. For example, a drainage structure is provided at a position close to the bottom of the heat dissipation bellows. The condensed water can be discharged through this drainage structure. In this example, the drainage structure has a drain port with a connecting pipe. Through the cooperation of a drainage connection structure such as a rubber hose and the connecting pipe, the condensed accumulated water can be drained to the aforementioned water collection box and further discharged to a structure / device such as a waste water box that can collect the condensed water, thereby ensuring the cleanliness of the equipment.

[0117] In this example, the bellows main body includes a vertically arranged partition plate. The outer edges of the partition plate extend with a first flanging and a second flanging towards the first heat dissipation chamber and the second heat dissipation chamber respectively. The first flanging, the partition plate and the front cover form the first heat dissipation chamber, and the second flanging, the partition plate and the rear cover form the second heat dissipation chamber. The drainage structure is arranged in the second heat dissipation chamber corresponding to the heat dissipation air outlet. For example, a drainage structure is provided at the bottom of the second flanging. The drainage structure is a drain port with a connecting pipe section extending below (the outer side of the bottom of the bellows main body). In order to ensure that the condensed water can gather better, for example, the bottom wall of the heat dissipation bellows corresponding to the drainage structure can be lower than other positions. Exemplarily, the bottom wall of the heat dissipation bellows is set as a structure (such as a curved surface structure, an inclined surface structure, etc.) that gathers towards the drainage structure.

[0118] Since gas condensation is more likely to occur at a position close to the heat dissipation air outlet, the drainage structure is arranged in the second heat dissipation chamber directly communicating with the heat dissipation air outlet. Therefore, the setting position of the drain port can be flexibly adjusted according to the adjustment method of the heat dissipation air outlet. Of course, a drainage structure can also be provided in the first heat dissipation chamber.

[0119] Obviously, the combination of the above partition plate and the two flangings is only an exemplary structural form of the bellows main body. Those skilled in the art can flexibly adjust it according to actual needs. For example, the two parts of the bellows main body are connected to each other after the first / second heat dissipation chambers are formed with the front / rear cover bodies respectively.

[0120] In a possible implementation manner, a drainage structure can be provided on the heat dissipation bellows. For example, the condensed water generated in the heat dissipation bellows can flow to a position corresponding to the aforementioned drainage structure and / or flow back to the first / second cooking chamber through the drainage structure. The drainage structure can include a guide plate, a guide groove, a horn-shaped guide pipe, etc. The drainage structure can be set specifically for the first cooking chamber and the second cooking chamber respectively, or one or more drainage structures can be set without specific targeting only from the perspective of the condensed water generated in the heat dissipation bellows. Exemplarily, the drainage structure is a planar / curved surface diversion plate arranged in the heat dissipation bellows along the width direction and inclined downward, and the condensed water can reach the drainage structure at the bottom through the diversion plate.

[0121] 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. For example, the first / second drainage structures are guide grooves and their structures are substantially the same. Further, in this example, the first / second drainage structures are disposed at positions corresponding to the aforementioned first / second air intake communication structures. In this way, for example, the condensed water generated in the heat dissipation air box can flow back to the first / second cooking chambers via the first / second drainage structures, the first / second air intake communication structures, and the first / second air outlet communication structures. It can be all flowing back, or partial flowing back (for example, a part flows back to the first / second cooking chambers, and a part is guided to the position of the drainage structure).

[0122] In a possible implementation manner, the first / second air outlet communication structures and the first / second air intake communication structures are disposed at positions near the upper part of the back of the heat dissipation air box. In this way, taking all flowing back as an example, during the process of realizing the collection of condensed water, the first-stage condensed water recovery can be carried out through the first / second drainage structures, that is, the first condensed water recovery structure flows back the recovered condensed water into the first / second cooking chambers. The second-stage condensed water recovery can be carried out through the drainage structure, that is, the second condensed water recovery structure discharges the recovered condensed water into a condensed water collection structure such as a waste water box (in the case of partial flowing back, the second condensed water recovery structure can be used as a supplement to the first condensed water recovery structure, and can supplement and recover the part of the condensed water collected by the first / second drainage structures but not flowing back into the first / second cooking chambers). For example, in order to achieve all flowing back, the guide groove can be set to be inclined towards the cooking chamber.

[0123] Obviously, the fact that the first / second drainage structures are substantially the same and the way they are aligned and communicated with the first / second air intake communication structures is only an exemplary description. Those skilled in the art can flexibly select the structural forms of the first / second drainage structures and the ways to realize the backflow according to actual needs. For example, the structural forms of the first / second drainage structures and the ways to realize the backflow can also be different. Exemplarily, the first drainage structure or the second drainage structure is an inclined guide plate, and the lowest part of the guide plate is communicated with the first cooking chamber or the second cooking chamber through a communication structure such as a communication hole or a communication pipe.

[0124] As in this example, the heat dissipation bellows is arranged at the back of the cooking body, and the heat dissipation bellows is roughly a volute-shaped structure. When observed along the width direction of the back of the cooking body, the heat dissipation bellows includes a first bellows part and a second bellows part. The upper part of the first bellows part is provided with a first heat dissipation air inlet, the back part is provided with a second heat dissipation air inlet, and the upper part of the second bellows part is provided with a heat dissipation air outlet. The first heat dissipation fan is arranged at the first bellows part, and the second bellows part is roughly located near the middle of the cooking body. The first / intake connecting structure is respectively arranged at the positions near each other of the first cooking cavity and the second cooking cavity, so that the heat dissipation fan assembly can be made more compact. Obviously, those skilled in the art can flexibly adjust the structural form of the heat dissipation bellows, the structure of the first / second bellows part, the first / second heat dissipation air inlet, the position of the heat dissipation air outlet, etc. to meet specific needs. For example, the heat dissipation air outlet is widened or another heat dissipation air outlet path is re-extended, and the second air intake connecting structure is arranged near the middle of the second cooking cavity, etc.

[0125] In a possible embodiment, the integrated cooking device includes a second heat dissipation portion 8 disposed on the stove unit 200, such as the stove unit 200 mainly includes a stove shell 6, the stove shell 6 has two stove installation positions, the two stove installation positions are provided with two stoves 7, and the second heat dissipation portion 8 is disposed in the stove shell. Obviously, those skilled in the art can determine the structural form and number of stove installation positions and the distribution of each stove installation position (when there are multiple stoves) on the stove surface according to actual needs.

[0126] In a possible implementation, the second heat dissipation portion 8 mainly includes a second heat dissipation air duct 81 and a second heat dissipation fan 82, such as the second heat dissipation fan 82 having 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 air duct, and the second air outlet side of the second heat dissipation air duct is connected to the external environment. In this way, the cross-flow fan can timely cool the heat-generating components such as electronic components inside the stove shell.

[0127] In a possible implementation, the air inlet of the crossflow fan is located on the side of the stove close to the operator (such as the front side), the air outlet of the crossflow fan is toward the side of the stove away from the operator (such as the rear side), and the second air outlet side of the second heat dissipation duct is located on the side of the stove away from the operator. It can be understood that, similar to the aforementioned first heat dissipation part, those skilled in the art can determine the way in which the air outlet side of the second heat dissipation duct is connected to the external environment according to actual needs, such as by using the existing structure of the stove or adding structures / components in the form of connecting ports, pipes, etc.

[0128] In a possible implementation, both the second air outlet side of the second heat dissipation air duct and the air outlet of the heat dissipation fan assembly are located near the rear of the cooking appliance assembly, and both need to discharge gas to the external environment. Therefore, in the example, a shared exhaust structure is provided on the cooking appliance unit.

[0129] On the one hand, those skilled in the art can determine the structural form of the exhaust structure according to actual needs. For example, it can be an exhaust pipe, an exhaust port, an exhaust hood, etc. On the other hand, obviously, the installation position of the exhaust structure does not necessarily have to be close to the rear side of the cooking appliance unit. That is, on the premise that exhaust can be achieved, those skilled in the art can also adjust the exhaust position of the exhaust structure.

[0130] In addition, sharing one exhaust structure is only a preferred implementation. Those skilled in the art can set 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 can include but is not limited to: the exhaust structure includes a main pipe and two branch pipes extending from the main pipe, and the two branch pipes are respectively connected to the exhaust positions of the first / second heat dissipation air ducts; the exhaust structure includes two closely arranged exhaust pipes, and the two exhaust pipes are directly connected to the external environment or connected to the external environment through the same exhaust port.

[0131] In a possible implementation, an exhaust area 61 is provided on the cooking surface (the upper surface of the stove shell) of the stove shell 6 as a shared exhaust structure. For example, the exhaust area can be an open structure, exhaust holes, exhaust mesh holes, etc. For example, the range hood configured on the side or above the cooking appliance can suck the gas delivered to the exhaust area 61 in time. In this way, in this embodiment, three kinds of heat-carrying gases can be discharged through the exhaust area 61: one is the heat-carrying gas from the first heat dissipation air duct (mainly used to cool the door assembly and the heat-generating components at the top of the steam oven), one is the cooking medium from the first / second cooking chambers (mainly used for pressure relief exhaust to ensure the cooking reliability of the steam oven), and one is the heat-carrying gas from the second heat dissipation air duct (mainly used to cool the heat-generating components inside the cooking appliance unit).

[0132] In a possible implementation, in order to ensure better connection between the exhaust area 61 of the cooking surface and the heat dissipation air outlet of the heat dissipation fan assembly, and at the same time to prevent the heat-carrying gas from entering the environment inside the stove 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.

[0133] It can be seen that in the preferred embodiment of the present application, by arranging the heat dissipation fan assembly on the back of the cooking body and adopting a vertically arranged centrifugal fan, the space at the top of the inner pot is effectively released, which can not only further increase the volume of the inner pot in the height direction, but also reduce the size of the device in the height direction, such as reducing the height of the top of the front door frame of the cooking device. By setting the heat dissipation bellows as a double heat dissipation chamber / heat dissipation air inlet, the integrated cooking device can be fully cooled by a double air inlet at one location. By integrating the exhaust and pressure relief structures for heat dissipation and corresponding to the two cooking cavities into the heat dissipation bellows, the cooking medium for exhaust and pressure relief to ensure cooking reliability can be discharged together with the heat dissipation air, that is, the first heat dissipation fan arranged on the back of the cooking body can not only dissipate heat for the door assembly and the related structures on the top / side, but also provide a path for the pressure relief gas to ensure the cooking reliability of the device. By converging the exhaust position (heat dissipation outlet) of the first heat dissipation part with the exhaust position (second exhaust side) of the second heat dissipation part and connecting them with the exhaust area on the stove assembly, the heat dissipation gas from the steam-bake combination machine and the stove assembly and the cooking medium from the exhaust pressure relief of the steam-bake combination machine can be discharged in a centralized manner, thereby improving the integration of the device. At the same time, the exhaust area can change the exhaust side corresponding to the first heat dissipation air duct from the front exhaust to the top exhaust, thereby avoiding the phenomenon of heat being directly sprayed onto the user's body parts (such as approximately the user's legs), thereby improving the user experience.
