Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and particularly relates to an integrated cooking device. 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 provide 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 provide 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 box 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 case, 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 emerged 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 to install 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, in adaptation to the relatively common built-in installation currently, there have also emerged combined devices such as a steam, roast, and fry integrated machine, and a combination of an integrated steam and roast oven and a cooking appliance unit such as a gas stove.

[0003] Taking the integrated steam and convection oven as an example, the cooking media for the two cooking methods of steaming and roasting are steam and hot air flow (which may also include steam) respectively. Therefore, heat dissipation is inevitably required 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 is required for the door body assembly). In addition, there are also related structures and components that need to be cooled in the cooking device, such as those located at the top, side, etc. 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 their long-term working state; on the other hand, the steam and hot air flow thermally radiate the top of the inner cavity where the components are located, etc., which will also cause their temperature to rise). In addition, in order to ensure the operation reliability of the cooking device, when the pressure in the cooking cavity is greater than a certain value, part of the cooking medium needs to be discharged. Obviously, the cooking medium to be discharged also carries heat. 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 and interfered with each other. In this way, on the premise of being able to effectively dissipate the heat of the cooking device and timely discharge the gas generated by heat dissipation / the cooking medium carrying heat, 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 partially solve the above technical problems and / or solve at least part of the above technical problems. Specifically, how to improve the integration of the device as much as possible while ensuring the timely discharge of the gas carrying heat (heat dissipation medium, cooking medium).

[0005] In view of this, this application provides an integrated cooking device, which includes: a cooking unit, which includes a first heat dissipation part, and the first heat dissipation part includes a heat dissipation fan assembly, and the heat dissipation fan assembly has an air outlet and at least one air inlet; a cooking appliance unit, which includes a cooking appliance housing and a second heat dissipation part, and the second heat dissipation part includes a second cooking appliance heat dissipation air duct arranged in the cooking appliance housing, and an exhaust area communicating with the external environment is arranged on the cooking appliance housing; and an exhaust connection assembly, which is respectively communicated with the heat dissipation fan assembly and the second heat dissipation air duct, so that: at least part of the gas from the air outlet of the heat dissipation fan assembly and the gas from the second heat dissipation air duct can reach the exhaust area through the exhaust connection assembly.

[0006] With such a configuration, it is possible to seek to timely discharge the heat-carrying gas from the cooking unit and the stove unit through the exhaust area, thereby ensuring the heat dissipation performance of the integrated cooking device. Through the setting of the exhaust connection assembly, it is possible to seek to discharge the gas more smoothly. And, since the exhaust path has a certain crossover part in the part of the two units close to the downstream side, by fusing the discharge paths of the heat-carrying gas to a certain extent, the integration degree of the device is improved to a certain extent. The external environment here can be understood as: directly discharging to the kitchen space (indoor space), or directly discharging the gas to the outdoor space through the range hood configured on the stove unit.

[0007] For the above-mentioned integrated cooking device, in a possible implementation manner, the exhaust connection assembly includes: an exhaust connection main body, which forms a connection air duct; and a partition structure, which can divide the connection air duct into a first connection air duct and a second connection air duct; wherein, the gas from the air outlet of the heat dissipation fan assembly and the gas from the second heat dissipation air duct respectively reach the exhaust area through the first connection air duct and the second connection air duct.

[0008] With such a configuration, it is possible to seek to discharge the gas from the air outlet of the heat dissipation fan assembly and the gas from the second heat dissipation air duct in a double-air-duct isolation manner, thereby avoiding interference between the double air ducts and improving the heat dissipation quality of the device.

[0009] For the above-mentioned integrated cooking device, in a possible implementation manner, the exhaust connection assembly includes: a first mesh structure, which is arranged in the first connection air duct; and / or a second mesh structure, which is arranged in the first connection air duct.

[0010] With such a configuration, it is possible to seek to effectively intercept foreign objects above the stove unit.

[0011] For the above-mentioned integrated cooking device, in a possible implementation manner, the exhaust connection assembly includes a collection box, the collection box includes a box body, the first mesh structure and / or the second mesh structure is arranged on the box body; and / or the partition structure is arranged on the box body.

[0012] With such a configuration, a possible structural form of the exhaust connection assembly composed of the first / second mesh structure and the partition structure is given.

[0013] For the above-mentioned integrated cooking device, in a possible implementation manner, the stove shell is provided with an exhaust cover plate having a connection structure at a position corresponding to the exhaust area.

[0014] With such a configuration, it is possible to effectively isolate foreign objects from entering the interior of the cooking unit / steam oven and grill through the exhaust connection component.

[0015] For example, through the combination of the exhaust cover plate and the aforementioned first / second mesh structures, the cleanliness of the interior of the integrated cooking device can be ensured by doubly isolating foreign objects. For example, it can also be achieved by arranging between the exhaust cover plate and the exhaust area.

[0016] For the above integrated cooking device, in a possible implementation manner, the cooking unit includes a first heat dissipation air duct, and the heat dissipation fan assembly includes: a heat dissipation air box, on which the at least one air inlet is provided, and the at least one air inlet includes a first air inlet and a second air inlet; and a heat dissipation fan, which is arranged in the heat dissipation air box; wherein, the gas in the first heat dissipation air duct can enter the heat dissipation air box through the first air inlet; wherein, the second air inlet is communicated with the installation space of the cooking main body.

[0017] With such a configuration, it is possible to better meet the heat dissipation requirements of the device for different regions by means of two-way air intake. Specifically, the heat dissipation medium from the first air inlet and the second air inlet is collected by the same heat dissipation fan assembly and discharged centrally, expanding the heat dissipation radiation area that the same heat dissipation fan assembly can share, thereby improving the integration of the heat dissipation fan assembly and the cooking device.

[0018] 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 manner.

[0019] It should be noted that the installation space of the cooking main body here should be understood as: the cooking main body includes an outer shell, an installation space is formed inside the shell, and the installation space houses an inner tank forming a 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, etc.

[0020] For the above integrated cooking device, in a possible implementation manner, the cooking main body includes at least one cooking chamber, the at least one air inlet includes a third air inlet, and the gas in the cooking chamber can enter the heat dissipation air box through the third air inlet.

[0021] With such a configuration, it is possible to further optimize the integration of the device and ensure the operational reliability of the cooking device. Specifically, the heat dissipation medium from different positions is collected and further discharged through the first / second air inlets, thereby effectively cooling components such as components. The gas from the cooking chamber is collected and further discharged through the third air inlet, thereby ensuring the reliability of the cooking device. It should be noted that the third air inlet here corresponds to the air intake connection structure in the specific implementation manner.

[0022] In a possible implementation manner, the first / second air inlets can be in a continuously connected state with the heat dissipation air duct; and / or the second air inlet can be in a connected or disconnected state with the heat dissipation air duct according to the pressure in the cooking chamber.

[0023] It can be 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 air duct and the structure on which it depends according to actual needs. For example, it can include but is not limited to: configuring a pressure relief valve at the third air inlet, and when the pressure in the cooking chamber is greater than a certain value, the pressure relief valve opens and part of the cooking medium is discharged; configuring a rotatable or telescopic plugging structure at the third air inlet, and when it is detected by an additional pressure detection component such as a pressure sensor that the pressure in the cooking chamber is greater than a certain value, the third air inlet is put into a state of being connected to the heat dissipation air box through the movement of the plugging structure and thus part of the cooking medium is allowed to be discharged.

[0024] For the above integrated cooking device, in a possible implementation manner, the heat dissipation air box includes an air outlet and includes 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 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 connected to the first heat dissipation chamber and / or the second heat dissipation chamber.

[0025] With such a configuration, it is possible to effectively dissipate heat from the device by means of double air intake.

[0026] 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, wherein 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.

[0027] In a possible implementation, at least a portion of the heat dissipation fan of the heat dissipation fan assembly is accommodated in the first heat dissipation chamber and / or the second heat dissipation chamber. Through such a configuration, a possible installation method of the heat dissipation fan is provided. 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, and in the case of being in only one of the chambers, it is necessary to achieve the connection between the two chambers by setting a connecting structure. For example, in addition to being in two heat dissipation chambers, there may also be a portion of the chamber extending out of the heat dissipation bellows.

[0028] For the above-mentioned integrated cooking device, in a possible implementation manner, an angle is formed between the exhaust direction of the air outlet of the heat dissipation fan assembly and the horizontal plane.

[0029] Through such a configuration, it is possible to avoid, at least to a certain extent, the problem of reduced user experience due to the air outlet blowing directly onto the user.

[0030] For the above-mentioned integrated cooking device, in a possible implementation manner, the exhaust direction of the air outlet of the heat dissipation fan assembly is substantially in a vertical direction.

[0031] Through such a structure, it is possible to effectively improve the user experience by means of vertical exhaust. For example, the substantially vertical direction here should be understood as: the setting direction of the air outlet (which may be the extension direction of its axis) and / or the airflow direction of the gas discharged through the air outlet can be considered to be substantially vertical, such as: having a small angle with the vertical direction (such as an angle less than 15°), or being a non-straight line substantially the same as the vertical direction; etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] The preferred implementation modes of the present application will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation modes are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application. For example, although this implementation mode is introduced for an integrated cooking device in combination with a steam oven and grill (including hot air grill and steam and grill) corresponding to the steam function and the grill function, and a cooker unit (in this example, the cooker unit includes two cookers) all arranged above the double - cavity steam oven and grill, where the steam oven and grill is of a double - cavity structure, this is not intended to limit the protection scope of the present application. Without departing from the principles of the present application, those skilled in the art can apply the present application to other application scenarios, such as a steam oven, fryer, and grill integrated machine. In addition, the double - cavity structure including a steam cavity and a grill cavity in the integrated cooking device is only an exemplary description. Those skilled in the art can adjust the relative positions between the two cavities (such as left - right, up - down, etc.), and can flexibly arrange the number, functions, etc. of the cavities, such as the cavities including one steam, one grill, one steam and grill, one steam and two grills, etc.

[0068] It should be noted that in the description of this application, the terms indicating directions or positional relationships such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional 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. Therefore, it should not be construed as a limitation to this application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0069] In addition, it should also be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "install", "set", "connect" 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 this application can be understood according to specific circumstances.

[0070] In addition, to better illustrate this application, numerous specific details are given in the following specific implementation manners. Those skilled in the art should understand that this application can still be implemented without some specific details. In some instances, details of well-known cooking appliances such as gas stoves and the principles of steaming / baking functions for those skilled in the art are not described in detail in order to highlight the gist of this application.

[0071] The integrated cooking device of this application will be described below with reference to at least a part of the Figures 1 to 16 drawings.

[0072] If the dual-chamber 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 chamber corresponding to the steam function cooking unit and the second cooking chamber corresponding to the convection function cooking unit. Among them, the structural form of adding an evaporation tray to the second cooking chamber 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 dual-chamber, 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, the same steam generating device (such as a steam generator) is configured for the first cooking chamber and the second cooking chamber, that is, the same steam generating device is used as the steam source for the dual-chamber. On this basis, by configuring the corresponding pipelines, logic, etc. for the dual-chamber, the evaporation supply for the dual-chamber is realized. In this way, there is still a certain room for improvement in related aspects such as the steam pipeline.

[0073] 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 arranged above the steam and convection oven 100. It can be installed in the kitchen in an embedded manner, effectively saving installation space and better integrating 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 placing 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. For example, a shelf can be arranged in the inner liner, and the ingredients to be cooked can be directly placed on the shelf or placed in a container (such as a plate) placed on the shelf. Or a placement structure such as a concave structure or a rotatable plate is arranged on the inner side of the bottom of the inner liner. The ingredients to be cooked can be directly placed on the placement structure or, after the ingredients to be cooked are placed in a container, the bottom of the container can be placed at a position corresponding to the placement 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 arranged 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 flowing in the second cooking chamber and / or the steam diffused in the first / second cooking chamber) can be mainly heated or assisted / supplemented heated.

[0074] In a possible implementation, the steam section 4 mainly includes a steam generating device 41, a first steam pipeline and a second steam pipeline that communicate 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. The steam generator is installed 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 clear water box, etc.). The steam generating device body forms a steam generating chamber and is equipped with steam generating heating components such as heating tubes. The clear water box 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. Corresponding to the first steam distribution port 431 of the first evaporation pipeline and the second steam distribution port 432 of the second evaporation pipeline, and the two steam distribution ports are arranged as close as possible to the two side walls of the cooking main body to minimize the probability of steam turbulence occurring between different working modes.

[0075] In a possible implementation, the steam section 4 includes a water collection box 44. The water collection 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 collection box. For example, the water after collection can be drained to a waste water box configured for the whole machine through the drainage pump. For example, the waste water box can be cleaned regularly and the accumulated water can be poured out. 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 select the specific form of the installation structure according to actual needs, such as installing the two in two separated structures, etc.

[0076] In this example, a chamber is provided at the bottom of the cooking main body, and the clear water box and the waste water box are both accommodated in the chamber at the bottom of the cooking main body.

[0077] 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 is constructed on the back side of the cooking main body (the area between the back regions of the two cooking units and the back of the housing 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.

[0078] In this example, the electronic control board is located below the heat dissipation fan assembly and on the side (in the width direction) away from the cooking unit corresponding to the baking function at the back. The steam generator is located below the heat dissipation fan assembly and at a position of 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 generally arranged below the electronic control board, and the water pump is generally 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 below, 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. For example, the steam generator, the water collection box, the water pump, etc. can be arranged in other integrated ways, and a part of the electronic control board can be arranged at the top.

[0079] 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, and a centrifugal fan is arranged in the hot air chamber. The 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.

[0080] Obviously, those skilled in the art can determine the structural form of the blower cover / back plate, its installation position relative to the cooking 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 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.

[0081] 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 and manner of the hot air chamber according to actual needs. Exemplarily, a restraining 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 restraining structure includes a plurality of limiting pieces arranged along the circumference of 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 restraining structure form the hot air chamber, or it can also be considered that the back plate and the blower cover provided with the restraining structure form the hot air chamber.

[0082] 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.

[0083] 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 along the circumference or a partial position of the circumference surrounding the air return port. For example, the centrifugal blower includes a motor and a fan, and the motor rotates to drive the fan to rotate at a position facing the air return port. 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 in the hot air chamber corresponding to the air return port, 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 flows through the air return port and is sucked into the hot air chamber, and then is heated by the heating tube 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 like this, 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.

[0084] In a possible implementation, the cooking main body 1 is provided with a door assembly that can be opened (such as pivoting open along the vertical / horizontal direction) on the operation side close to the user (if the operation side is the side facing the user, it is usually called the front side). For example, one door assembly can be configured for each of the two inner liners, or the 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.

[0085] Under normal circumstances, in order to ensure the performance of the integrated cooking device, the working environments of the door, the power board, and related electrical components with temperature requirements (such as those set on the top, back, etc. of the cooking main body) need to be within a certain temperature range. After combining the steaming function cooking unit, the baking function cooking unit, and the cooking stove unit, more heat may be generated in the limited space. In this case, 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 synchronous operation of the two cavities. 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 may lead to poor heat dissipation of the device.

[0086] In a possible implementation, the integrated cooking device includes a first heat dissipation part 5 provided 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 provided on 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.

[0087] Under normal circumstances, the heat dissipation fan assembly is a cross-flow fan provided on 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 also limit the increased space of the inner liner volume in the height direction. Therefore, in this application, the heat dissipation fan assembly is provided on the side of the cooking main body.

[0088] As in this example, the heat dissipation fan assembly 52 is disposed on the back side of the cooking main body. More specifically, in this example, the heat dissipation 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 of the device to a certain extent.

[0089] In a possible implementation manner, the heat dissipation fan assembly 52 mainly includes a heat dissipation air box 521 and a first heat dissipation fan 522. For example, if the first heat dissipation fan is a centrifugal fan, the heat dissipation 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 heat dissipation chamber 5214 (which can be called a front heat dissipation chamber for example) is defined between the air box main body and the front cover body, and a second heat dissipation chamber 5215 (which can be called a rear heat dissipation chamber for example) is defined between the air box main body and the rear cover body. The first heat dissipation chamber 5214 and the second heat dissipation chamber 5215 communicate with each other, and the first heat dissipation fan 522 is installed in the heat dissipation air box. As in this example, a part of the first heat dissipation fan 52 is in the front heat dissipation chamber and a part is in the rear heat dissipation chamber. Therefore, the two heat dissipation chambers can communicate with each other by virtue of the installation of the first heat dissipation fan. It can also be that the first heat dissipation fan is only in one of the two heat dissipation chambers, and the two heat dissipation chambers communicate with each other through a communication structure such as a communication hole.

[0090] Obviously, the combination of the front and rear cover plates and the air box main body is only an exemplary composition form of the heat dissipation 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 heat dissipation air box and the rear wall of the inner container form a heat dissipation chamber. In addition, those skilled in the art can determine the structural form, coverage area of the front / rear cover plates, and the connection method between the two and the air box main body according to actual needs.

[0091] In a possible implementation manner, the heat dissipation air box is provided with a first heat dissipation air inlet 5216 at a position communicating with the first heat dissipation chamber, and a second heat dissipation air inlet 5217 and a heat dissipation air outlet 5218 at a position communicating with the second heat dissipation chamber. The first air outlet side of the first heat dissipation air duct can be connected to the first heat dissipation air inlet, and the second heat dissipation air inlet can be directly connected to the back side space of the cooking main body of the integrated cooking device. As in this example, the first heat dissipation air inlet and the heat dissipation air outlet are disposed at the top of the heat dissipation air box, and the second heat dissipation air inlet is disposed at the back side of the heat dissipation air box.

[0092] 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.

[0093] 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 respectively called 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).

[0094] For the first negative pressure zone among them, under the guidance of the first heat dissipation fan, the air entering the first heat dissipation air duct from 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 connected directly (such as sleeved connection), indirectly connected through an intermediate pipe section, aligned (such as there may be no connection relationship), etc. to achieve the docking between the two.

[0095] 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 zone among them, under the guidance of the first heat dissipation fan, the heated gas enters the second heat dissipation chamber through the second heat dissipation air inlet and is then discharged through the heat dissipation air outlet.

[0096] It can be seen that through the combination of the heat dissipation fan assembly (the first heat dissipation air inlet) 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.

[0097] 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 adjust them flexibly according to actual needs. For example, the heat dissipation air outlet can be directly connected to both the first / 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 methods for the heat dissipation air outlet to be directly connected to 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 connected to the first / second heat dissipation chambers, the heat dissipation air outlet includes two branch pipes on the upstream side respectively connected to the first / second heat dissipation chambers and a main pipe on the downstream side respectively connected to the two branch pipes, etc.

[0098] In a possible implementation, the first heat dissipation air duct 51 covers the steaming function cooking unit and the baking function cooking unit along the width direction of the device at the same time, so that the heat dissipation function of the device can be more fully realized. For example, the first heat dissipation air duct may include one or more. In the case where there are multiple first heat dissipation air ducts, the structural form of the multiple first heat dissipation air ducts and their layout manner at the top can be flexibly adjusted. Exemplarily, a plurality of heat dissipation sub-air ducts extend from the first air outlet side of the first heat dissipation air duct, and the first air inlet side of each heat dissipation sub-air duct is docked with different regions, such as a certain heat generating component, the side of the cooking main body, another first heat dissipation air duct, a non-heat generating region (i.e., a region capable of drawing natural wind into the first heat dissipation air duct), etc.

[0099] In a possible implementation, the first air inlet side 511 of the first heat dissipation air duct is located at the front side of the cooking main body, such as being arranged on the front door frame of the cooking main body, while the first air outlet side 512 is docked with the heat dissipation air inlet of the first heat dissipation air duct assembly at the back side. In this way, the first heat dissipation air duct straddles two cooking units in the width direction of the cooking main body, and the heat dissipation paths that are roughly diagonally arranged with the right front and the left rear further increase the length of the first heat dissipation air duct. Therefore, it is expected to more fully dissipate heat from the relevant components.

[0100] It should be noted that the so-called diagonal arrangement should be understood as that after the arrangement direction in the front-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-right direction, so as to appropriately lengthen the length of the first heat dissipation air duct.

[0101] In a possible implementation, the first air inlet side of the first heat dissipation air duct is located in the heat dissipation region (such as a heat dissipation port is provided in the heat dissipation region) of the second door body assembly 152 corresponding to the baking function cooking unit, such as at least somewhat aligned with the heat dissipation port of the second door body assembly or near the heat dissipation port. In this way, while the heat dissipation fan assembly dissipates heat from the heat generating components in the top region, it can also share at least part of the heat dissipation for the second door body assembly.

[0102] It should be noted that the so-called at least somewhat aligned with the heat dissipation region of the second door body assembly mainly refers to the alignment in terms of orientation. Since the first / second door body assemblies for the steaming / baking function cooking units are adjacent to each other, therefore, in addition to dissipating heat from the second door body assembly, the heat dissipation fan assembly can also undertake part of the heat dissipation for the first door body assembly. Preferably, in order to better dissipate heat from the first door body assembly mechanically, the first heat dissipation air duct can be widened at a position close to the first air outlet side so that it is at least somewhat aligned with the heat dissipation regions of the first / second door body assemblies, or a communication hole can be added at a position of the first heat dissipation air duct close to the first air outlet side or a communication section capable of introducing the heat from the first door body assembly 151 can be extended.

[0103] In addition, under the guidance of a cross-flow fan arranged on the top of the cooking body, the air carrying heat is usually discharged forward from the door gap of the door body assembly. The heat dissipation method of the front row will cause the heat to blow directly to the user (as in this example, roughly the position of the user's legs), thereby reducing the user experience.

[0104] In a possible embodiment, the integrated cooking device includes an exhaust structure that is arranged at an angle with the horizontal direction and can discharge the air carrying heat in an upward direction. For example, the air carrying heat can be discharged upward at a large angle (such as ≥60°) with the horizontal direction. Exemplarily, it is discharged in a substantially vertical direction. The heat dissipation exhaust structure can be a separately added structure or a structure that is completed in collaboration based on the components of the integrated cooking device. For example, the heat dissipation exhaust structure can be a heat dissipation exhaust port, a heat dissipation exhaust duct extending upward connected to the heat dissipation outlet, a structure connected to the stove unit above, etc. Taking the exhaust duct as an example, the downstream side of the exhaust duct can be connected to the indoor space, directly connected to the outdoor environment, connected to the outdoor environment through a duct that can be connected to the outdoor environment (such as the duct of the range hood), etc.

[0105] As in this example, the integrated cooking device is provided with a stove unit 200 above the steam-bake combination machine. For example, the heat dissipation outlet 5212 can be provided above the heat dissipation bellows, and the heat dissipation outlet is connected to the stove surface part of the stove unit, thereby switching the heat front row to the heat upper row. For example, a range hood is usually provided above the stove unit (such as the top or the side), and the exhaust air carrying heat can be promptly extracted by the range hood, thereby avoiding the temperature increase of the indoor space caused by this. For example, the way of connecting the heat dissipation outlet with the stove surface part of the stove unit can be achieved by configuring a pipeline, adding a connecting hole and other connecting structures on the stove surface part, and directly aligning the heat dissipation outlet with the position (stove opening) on ​​the stove surface part of the stove unit where exhaust can be performed.

[0106] In a possible embodiment, the cooking body is provided with air outlet communication structures for exhaust and pressure relief corresponding to the steaming function cooking unit and the baking function cooking unit (respectively recorded as the first air outlet communication structure and the second air outlet communication structure, the first air outlet communication structure and the second air outlet communication structure are respectively connected to the heat dissipation bellows, so that under the action of the first heat dissipation fan, the depressurized gas is discharged through the aforementioned heat dissipation outlet. For example, the air outlet communication structure may include one or more communication holes.

[0107] 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 and coming from 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 position of the second heat dissipation chamber close to the heat dissipation air outlet). Similarly, the gas discharged upward can be timely sucked away by the range hood at the top / side of the cooker. 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) from the first / second cooking chambers ensures the cooking quality in the first / second cooking chambers through the way of exhausting and relieving pressure. Since this part of the gas belongs to the cooking medium, especially for the gas from 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 indoor space from warming up at the same time.

[0108] 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.).

[0109] Compared with the current common method of setting a pressure relief port at the top of the inner container, 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.

[0110] 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 near the bottom of the heat dissipation bellows, and the condensed water can be discharged through this drainage structure. In this example, the drainage structure has a drain port with a connecting pipe, and 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, thus ensuring the cleanliness of the equipment.

[0111] In this example, the bellows main body includes a vertically arranged partition board. The outer edges of the partition board extend with a first flanging and a second flanging towards the directions of the first heat dissipation chamber and the second heat dissipation chamber respectively. The first flanging, the partition board and the front cover body form the first heat dissipation chamber, and the second flanging, the partition board and the rear cover body 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 downward (outside 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 set 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.

[0112] 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.

[0113] Obviously, the combination of the above partition board and the two flangings is only an exemplary structural form of the bellows main body, and those skilled in the art can flexibly adjust it according to actual needs. For example, the bellows main body has two parts, and after the two parts form the first / second heat dissipation chambers with the front / rear cover bodies respectively, they are connected to each other.

[0114] 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 the 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 guiding plate, a guiding groove, a horn-shaped guiding 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.

[0115] 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 reflux, or partial reflux (for example, part flows back to the first / second cooking chambers, and part is guided to the position of the drainage structure).

[0116] 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 reflux as an example, during the process of realizing condensed water collection, for example, 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 reflux, 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 reflux, the guide groove can be set to be inclined towards the cooking chamber.

[0117] Obviously, the fact that the first / second drainage structures are substantially the same and their way of aligning and communicating 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 achieve reflux according to actual needs. For example, the structural forms and the ways to achieve reflux of the first / second drainage structures 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.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] 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 unit, and both need to discharge gas to the external environment. Therefore, in the example, a shared exhaust structure is provided on the cooking unit.

[0123] 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 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.

[0124] 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.

[0125] In a possible implementation, an exhaust area 61 is provided on the cooking surface of the stove shell 6 (the upper surface of the stove shell, such as the top layer is usually cooking surface glass) as a shared exhaust structure. For example, the exhaust area can be an open structure or be equipped with 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. For example, in this example, an exhaust cover plate 611 with a communication structure such as an exhaust mesh (such as a spider web structure) is provided at the exhaust area of the cooking surface (such as the position of the cooking surface glass), which not only plays a role in isolating foreign objects but also reduces the air volume loss. For example, a sealing structure 612 such as a sealing ring is provided between the exhaust cover plate and the cooking surface glass. On the one hand, the sealing structure can prevent the liquid escaping from the cooking surface glass from entering the stove shell, and on the other hand, it can prevent problems such as poor sealing of the air duct path caused by deformation of injection molded parts. In this way, in this embodiment, three kinds of heat-carrying gases can be discharged through the exhaust mesh: 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 chamber (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 unit).

[0126] 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 the air outlet side of the second heat dissipation fan, for example, an exhaust connection assembly 62 can be provided at a position close to the exhaust area. Refer to Figure 14 , such as the exhaust connection assembly 62 can be a corrugated pipe (to prevent the heat-carrying gas from the heat dissipation air outlet from entering the environment inside the stove shell). However, the structure of the corrugated pipe is relatively simple. The present application proposes an exhaust connection assembly with better effect for the two paths of gas to be discharged corresponding to the steam oven and the cooking unit. Specifically, an exhaust connection assembly that can be more adapted to the discharge of the two heat-carrying media.

[0127] Refer to Figure 15 , in a possible implementation, the exhaust connection assembly 62 mainly includes an exhaust connection main body 621. On the one hand, the exhaust connection main body is respectively communicated with the second exhaust side of the second heat dissipation air duct and the air outlet of the first heat dissipation fan to collect the heat-carrying medium. On the other hand, it is communicated with the exhaust area 61 provided on the cooking surface to timely discharge the collected heat-carrying medium.

[0128] In a possible implementation, a connection structure 622 is provided at the position of the exhaust connection main body 621 close to the heat dissipation air outlet in an integrally formed or fixedly connected manner. For example, the exhaust connection main body 621 is connected to the heat dissipation air outlet 5218 of the heat dissipation air box 521 through the exhaust connection structure 622 (such as including not only alignment, alignment and proximity (without connection relationship), connection relationship, etc.). In this example, the upper part of the exhaust connection structure is fixed to the exhaust connection main body, and the cross-section of the exhaust connection structure is generally adapted to the heat dissipation air outlet, and thus is connected to the heat dissipation air outlet 5218 by plugging at the lower part.

[0129] In this example, the upper part of the exhaust connection structure is fixed to the exhaust connection main body by a combination of clamping and screwing. The cross-section of the exhaust connection structure is generally adapted to the heat dissipation air outlet, and thus is connected to the heat dissipation air outlet 5218 by plugging at the lower part. Obviously, this is only an exemplary description. Those skilled in the art can flexibly select the structural form of the exhaust connection structure and its connection relationship with the exhaust connection main body / heat dissipation air outlet according to actual needs. For example, the exhaust connection structure can be connected to the exhaust connection main body by screwing, sleeving, etc.

[0130] In a possible implementation, the exhaust connection body 621 is provided with a connection structure capable of connecting thereto at a position near the air outlet side of the second heat dissipation air duct. For example, the connection structure may include a plurality of connection ports arranged along the width direction (axial direction of the cross-flow fan) of the air outlet side. For example, the connection between the air outlet side of the second heat dissipation air duct and the exhaust connection body may also include not being close to but only aligned with, close to and aligned with (without a connection relationship), having a connection relationship, etc. In this example, the second heat dissipation air duct is a horn-shaped structure that gradually expands from its air inlet side to the air outlet side, and the position of the second heat dissipation air duct corresponding to the air outlet side is connected to the position of the exhaust connection body corresponding to the connection structure.

[0131] In a possible implementation, the exhaust connection body 621 is generally a cylindrical structure with a rectangular cross-section. An access duct is formed inside the cylindrical structure. The bottom of the cylindrical structure is connected to the heat dissipation air outlet through an exhaust connection structure, and the side of the cylindrical structure is connected to the second heat dissipation air duct.

[0132] In a possible implementation, a collection box 623 is arranged inside the cylindrical structure. The collection box mainly includes a box body 6231 arranged substantially horizontally (such as including a main body and a flange extending upward along the height direction from the outer edge of the main body) and a partition structure (such as a partition plate, a partition block, etc.) 6232 arranged substantially vertically. The box body 6231 has a first mesh structure 62311 corresponding to the heat dissipation air outlet and a second mesh structure 62312 corresponding to the second heat dissipation air duct. The partition structure divides the access duct into a first access duct corresponding to the heat dissipation air outlet and a second access duct corresponding to the second heat dissipation air duct. For example, the first mesh structure and the second mesh structure are respectively arranged in the first access duct and the second first mesh structure.

[0133] In this example, the first mesh structure is a planar structure adapted to the heat dissipation air outlet, and the second mesh structure is an inclined surface structure adapted to the horn-shaped second heat dissipation air duct. For example, the angle between the second mesh structure and the horizontal plane is 30 - 60°. Exemplarily, the angle between the second mesh structure and the horizontal plane is 45°. For example, positioning card slots are provided on the inner wall of the cylindrical structure, and the box body is arranged inside the cylindrical structure by means of its cooperation with the positioning card slots. And in the assembled state, the box body is generally located near the bottom of the cylindrical structure. In this way, the partition structure plays a role in isolating and paralleling the double air ducts on the one hand, and also plays a role as a handle. For example, during use, when the user needs to clean foreign objects, they can pull out the handle upward by hand to take out the foreign objects collected by the first / second mesh structure together with the handle.

[0134] Obviously, the above structure is only an exemplary description of the exhaust connection body and the collection box. Those skilled in the art can adjust it according to actual needs. For example, the first / second mesh structure is an integrated planar structure, and the exhaust connection body and the collection box are connected by other means (such as the collection box can be freely accommodated in the exhaust connection body and fixedly connected to the bottom of the exhaust connection body by snap connection, etc.).

[0135] For example, for an integrated cooking device including a stove unit and a steam oven, such a heat dissipation solution has emerged on the market: a centrifugal fan is arranged in the stove shell of the stove unit, and the lower end of the centrifugal fan is opened to communicate with the steam oven for heat dissipation. In this way, a single fan can simultaneously meet the heat dissipation requirements of the upper stove unit and the lower steam oven. For example, a connecting structure such as a hose is also needed to connect with the wastewater box of the steam oven to realize the water body reflux in the form of condensed water, etc. However, in this solution, a single fan cannot regulate the air volume of the two parts (the inside of the stove unit and the heat dissipation air duct of the steam oven), and can only be passively distributed through negative pressure, and the degree of meeting the heat dissipation requirements needs to be further improved. Correspondingly, since a large number of ventilation holes cannot be opened at the front end of the stove shell (opening a large number of ventilation holes will reduce the negative pressure inside the stove unit. In this way, the centrifugal fan cannot absorb the heat of the steam oven well, thus affecting the heat dissipation level of the whole machine), it will affect the heat dissipation level of the stove unit to a certain extent. And when installing the centrifugal fan, two hoses need to be manually connected to the stove unit and the steam oven, which is inconvenient for installation. In addition, this heat dissipation solution also has the disadvantage of poor ability to isolate and collect foreign objects.

[0136] In contrast, in the preferred embodiment of the present application, parallel heat dissipation is carried out by using a double fan (a centrifugal fan corresponding to the steam oven and a cross-flow fan corresponding to the stove unit). Since the two flow fields do not interfere with each other (except for the position close to the exhaust area, but the gas in the exhaust area can be timely sucked away by the range hood configured in the stove unit, so even if the flow fields interfere with each other in this area, it basically has no impact on the heat dissipation performance of the whole machine), for example, the fan can be flexibly replaced, the operating parameters of the fan can be adjusted, the structural parameters of the flow field domain can be adjusted, etc. according to actual needs, effectively avoiding the problem of only being able to passively distribute the heat dissipation capacity for the stove unit and the steam oven through negative pressure. Also because the two flow fields do not interfere with each other, more ventilation holes can be opened at the front end of the stove shell, so that the stove unit can be fully cooled by fully inhaling the air (low temperature) in front of the stove. By directly inserting the exhaust connection structure into the heat dissipation air outlet, the stove unit and the steam oven can be connected, which is convenient for installation and has high connection accuracy. Through the combination of the exhaust cover plate and the collection box, foreign objects can be isolated doubly, thus effectively preventing foreign objects from falling in and facilitating the removal of the collected foreign objects.

[0137] 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 main body and using a vertical centrifugal fan, the space at the top of the inner container is effectively released. This can not only further increase the volume of the inner container 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 air box in the manner of a double heat dissipation chamber / heat dissipation air inlet, the integrated cooking device can be fully cooled by double air inlet at one position. By integrating the structures for heat dissipation and exhaust pressure relief corresponding to the two cooking chambers into the heat dissipation air box, the cooking medium for exhaust 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 main body can not only dissipate heat for the door body assembly and related structures at the top / sides but also ensure the cooking reliability of the device by providing a path for the pressure relief gas. By converging the exhaust position (heat dissipation air outlet) of the first heat dissipation part and the exhaust position (second exhaust side) of the second heat dissipation part and connecting them to the exhaust area on the cooking unit, the heat dissipation gas from the steam oven and cooking unit and the cooking medium for exhaust pressure relief from the steam oven can be discharged centrally, improving the integration degree of the device. At the same time, the exhaust area can change the exhaust side corresponding to the first heat dissipation air duct from front exhaust to top exhaust, avoiding the phenomenon of heat directly spraying onto the user's body part (such as roughly the user's legs), thus enhancing the user experience.

[0138] So far, the technical solutions of the present application have been described in combination with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments. Without departing from the principle of the present 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 protection scope of the present application.
