Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and more particularly to an integrated cooking device and a heat dissipation fan assembly thereof. The integrated cooking device including the heat dissipation fan assembly of the present application is more suitable for fully embedded / embedded installation. Background Art

[0002] There's a significant user demand for both steaming and baking. Steaming involves continuously supplying high-temperature steam to the inner container of the food, allowing the food to be cooked purely through steaming. Baking involves continuously circulating a hot air flow through the inner container, allowing the food to be cooked through hot air baking. Accordingly, the most basic form of kitchen appliance is a steamer for steaming and an oven for baking. With the increasing sophistication of kitchen appliances, a combination of steaming and baking (such as tender baking) has emerged. This requires the addition of steam-generating components, such as evaporating trays, to the oven, which provide steam (the cooking medium for steaming). These components are equipped with corresponding steam delivery piping and control logic. Because the two cooking media overlap (steam), steam-baking and baking functions (including both baking and steaming) have emerged on the market. Furthermore, given the limited space available in kitchens for cooking equipment, users are increasingly seeking to fit as many multifunctional appliances as possible within this limited space. Therefore, oven-steamers with a certain degree of integration can meet this demand. Furthermore, to accommodate the currently common embedded installation, the market has also seen the emergence of oven-steamers, oven-fryers, and combination ovens with gas stoves.

[0003] Take the combination of a steam-bake machine and a gas stove as an example. For the steam-bake machine, the cooking media for steaming and baking are steam and hot air flow (which may also include steam), respectively. Therefore, there will inevitably be a need for heat dissipation during the cooking process, such as heat dissipation of the door assembly (for example, steam and hot air flow radiate heat to the door assembly, thereby increasing its temperature. The door assembly is close to the user, and for safety reasons, heat dissipation of the door assembly is required). In addition, there are related structures and components in the cooking equipment that require heat dissipation, such as those located at the top, side, etc. For example, the working reliability of the components is affected by temperature (for example, on the one hand, the components themselves are heat sources and will therefore heat up due to being in a long working state. On the other hand, the heat radiated by steam and hot air flow to the top of the inner pot where the components are located will also cause their temperature to rise). For the gas stove, the part close to the stove is a heat radiation area, and the components that need to be dissipated therein are also heat-generating components. Since the cooking equipment has multiple functions, the amount of heat that needs to be dissipated will increase. Since cooking equipment itself has a certain degree of integration, various heat may overlap and interfere with each other. As a result, there is considerable room for improvement in how to effectively dissipate heat from cooking equipment. Utility Model Content

[0004] The present 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 dissipating heat for an integrated cooking device that includes multiple functions.

[0005] In a first aspect, the present application provides a heat dissipation fan assembly of an integrated cooking device, the device including a cooking body, the cooking body including an evaporation portion and at least one cooking cavity, the evaporation portion being capable of releasing steam to the at least one cooking cavity, the heat dissipation fan assembly including: a heat dissipation bellows, which can be arranged on the cooking body and includes an air outlet and an air intake connecting structure; and a heat dissipation fan, which is arranged on the heat dissipation bellows; wherein the gas in the at least one cooking cavity can enter the heat dissipation bellows via the air intake connecting structure and be discharged through the air outlet; wherein a drainage structure is provided on the heat dissipation bellows.

[0006] This configuration improves the device's integration and ensures operational reliability. Specifically, while the heat dissipation fan achieves heat dissipation, it also collects and exhausts air from the cooking chamber, ensuring the reliability of the cooking device. Furthermore, by promptly draining water from the heat dissipation bellows, the cleanliness of the device is ensured. For example, the air intake connection structure can be either connected or disconnected to the heat dissipation duct depending on the pressure within the cooking chamber.

[0007] It is understood that those skilled in the art can determine the switching method for the connection between the air intake communication structure and the heat dissipation bellows and the structure to which it is dependent based on actual needs. For example, these methods may include, but are not limited to: disposing a pressure relief valve on the air intake communication structure, which opens to partially discharge the cooking medium when the pressure in the cooking chamber reaches a certain value; disposing a rotatable or retractable blocking structure on the air intake communication structure, which moves to connect the air intake communication structure to the heat dissipation bellows and thereby allow a portion of the cooking medium to be discharged when an additional pressure sensing component, such as a pressure sensor, detects that the pressure in the cooking chamber reaches a certain value.

[0008] For the heat dissipation fan assembly of the above-mentioned integrated cooking device, in a possible embodiment, the heat dissipation bellows is provided with a drainage structure, which can guide the liquid in the heat dissipation bellows to the cooking cavity and / or a position corresponding to the drainage structure.

[0009] Through such a structure, the condensed water generated in the heat dissipation bellows can be discharged more smoothly, thereby further ensuring the cleanliness of the integrated cooking device.

[0010] For the heat dissipation fan assembly of the above-mentioned integrated cooking device, in one possible embodiment, the drainage structure is arranged at a position of the heat dissipation bellows corresponding to the air intake connecting structure, so that: the liquid in the heat dissipation bellows is guided to the cooking cavity through the drainage structure and the air intake connecting structure.

[0011] Through such a composition, a specific drainage method is provided.

[0012] It should be noted that "the drainage structure is provided at a position of the heat dissipation air box corresponding to the air intake connecting structure" should be understood as follows: the drainage structure and the air intake connecting structure can be connected to each other to form a liquid channel, and because the drainage structure has directional structural features such as a slope, the downstream side of the channel is defined. For example, the drainage structure and the air intake connecting structure can be directly connected or indirectly connected via an intermediate connecting structure. Exemplarily, the drainage structure is an arc-shaped groove integrally formed with the air intake connecting structure (such as an air intake connecting hole or an air intake connecting pipe).

[0013] Regarding the heat dissipation fan assembly of the above-mentioned integrated cooking device, in a possible implementation manner, the device includes a water collection box, and liquid can flow to the water collection box through the drainage structure.

[0014] This configuration provides a drainage path for condensed water and other liquids collected in the drainage structure. For example, the drainage structure and the water collection box can be connected by a hose, a rigid pipe, etc. For example, the drainage structure is a drain port, a drain pipe, etc., and the water collection box is located directly below the drainage structure. The drainage structure and the water collection box can be connected by direct alignment, a rigid pipe, or a hose.

[0015] For the heat dissipation fan assembly of the above-mentioned integrated cooking device, in a possible embodiment, the device includes a cooking body and a heat dissipation air duct, and the heat dissipation air box is provided with a first air inlet and a second air inlet, wherein the gas in the heat dissipation air duct can enter the heat dissipation air box through the first air inlet; wherein the second air inlet is connected to the installation space of the cooking body.

[0016] This configuration allows for better meeting the heat dissipation requirements of different areas of the device through bidirectional air intake. Specifically, by collecting and centrally discharging the heat dissipation medium from the first and second air inlets through the same heat dissipation fan assembly, the heat dissipation radiation area that can be shared by the same heat dissipation fan assembly is expanded, thereby improving the integration of the heat dissipation fan assembly and the cooking device. It should be noted that the first and second air inlets herein correspond to the first and second heat dissipation air inlets in the specific embodiment.

[0017] It should be noted that the installation space of the cooking body here should be understood as: the cooking body includes an outer shell, and an installation space is formed inside the shell. The installation space accommodates an inner tank forming a cooking cavity, and related structures such as heat dissipation ducts, components, and heat dissipation fan assemblies arranged on the outside. There is a certain margin between the installation space and these structures accommodated therein. The second air inlet is mainly used to meet the heat dissipation needs of the surface of the structure accommodated therein and the part close to the surface, such as the installation space in the side, bottom, etc.

[0018] Thus, in a preferred embodiment of the present application, heat dissipation medium from different locations is collected and further discharged through the first / second air inlet, thereby effectively cooling components and other parts. Gas from the cooking chamber is collected and further discharged through the air intake communication structure, thereby ensuring the reliability of the cooking device.

[0019] In a possible embodiment, the at least one cooking cavity includes a plurality of cooking cavities, at least one of the plurality of cooking cavities is a steaming-function cooking cavity for cooking food by pure steaming, the heat dissipation fan assembly and / or at least a portion of the evaporation portion is arranged on a side of the cooking body corresponding to or close to the steaming-function cooking cavity; and / or the cooking body includes an electric control board, which is arranged on a side of the cooking body corresponding to or close to the steaming-function cooking cavity.

[0020] For the heat dissipation fan assembly of the above-mentioned integrated cooking device, in a possible embodiment, the heat dissipation air box includes a first heat dissipation chamber and a second heat dissipation chamber 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.

[0021] With this structure, it is possible to effectively dissipate heat from the device through dual-chamber air intake.

[0022] In a possible embodiment, the heat dissipation bellows includes a bellows body, a first cover body and a second cover body, wherein the bellows body and the first cover body form the first heat dissipation chamber, and the bellows body and the second cover body form the second heat dissipation chamber.

[0023] Through such a structure, a possible structural form of the bellows main body is given.

[0024] In a possible implementation, the heat dissipation fan assembly includes a heat dissipation fan, and at least a portion of the heat dissipation fan is accommodated in the first heat dissipation chamber and / or the second heat dissipation chamber.

[0025] This configuration provides a possible installation method for the cooling fan. For example, if the cooling fan is located in two cooling chambers, the two cooling chambers can be connected due to the installation of the cooling fan. However, if the cooling fan is located in only one chamber, a connecting structure is required to achieve the connection between the two chambers. For example, in addition to being located in two cooling chambers, the cooling fan can also extend beyond the chamber of the cooling fan.

[0026] In a possible embodiment, the heat dissipation fan is a centrifugal fan, and / or the first air inlet is arranged near the top of the heat dissipation air box; and / or the second air inlet is arranged on the side of the heat dissipation air box.

[0027] Through such a configuration, a possible structural form of the heat dissipation fan assembly is provided.

[0028] In a possible embodiment, the cooking body includes a door assembly disposed in the cooking cavity, and the heat dissipation duct includes an air inlet side, and heat from the door assembly can enter the heat dissipation duct through the air inlet side.

[0029] This configuration allows for a certain degree of cooling of the door assembly through the heat dissipation duct. It is understood that those skilled in the art can determine how to allow heat from the door assembly to enter the heat dissipation duct via the air inlet side based on actual needs. For example, the air inlet side can be positioned near the door assembly, or the air inlet side can be aligned with the heat dissipation vents on the door assembly to at least a certain degree. It should be noted that the air inlet side herein corresponds to the first air inlet side in the specific embodiment.

[0030] Regarding the heat dissipation fan assembly of the above-mentioned integrated cooking device, in a possible implementation manner, an angle is formed between the exhaust direction corresponding to the air outlet and the horizontal plane.

[0031] With 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 at the user.

[0032] Regarding the heat dissipation fan assembly of the above-mentioned integrated cooking device, in a possible implementation manner, the exhaust direction corresponding to the air outlet is substantially vertical.

[0033] This structure effectively improves the user experience through vertical exhaust. The term "substantially vertical" here should be understood to mean that the direction in which the air outlet is located (which may be the direction in which its axis extends) and / or the direction of the airflow discharged through the air outlet can be considered to be substantially vertical, such as having a small angle with the vertical direction (e.g., an angle less than 15°), or being a non-straight line substantially parallel to the vertical direction, etc.

[0034] In a second aspect, the present application provides an integrated cooking device, which includes the heat dissipation fan assembly of any of the aforementioned integrated cooking devices.

[0035] It can be understood that the integrated cooking device has all the technical effects of the heat dissipation fan assembly of the integrated cooking device described in any of the above items, which will not be repeated here.

[0036] For the above-mentioned integrated cooking device, in a possible embodiment, the device includes a stove unit, which is arranged above the cooking body, and an exhaust area that can communicate with the external environment is provided on the stove unit or near the stove unit, and the gas in the heat dissipation bellows is discharged to the external environment through the air outlet and the exhaust area.

[0037] This structure allows for the timely discharge of heat-carrying gases upwards. Furthermore, this integration facilitates fully embedded or fused installation in kitchens and other installation scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0082] The preferred embodiments of the present application are 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 principles of the present application and are not intended to limit the scope of protection of the present application. For example, although this embodiment is combined with a steam-bake-in-one machine including steaming and baking (including hot air baking and steam-bake) functions and a stove assembly all arranged above a double-cavity steam-bake-in-one machine (such as in this example, the stove assembly includes two stove units), wherein the steam-bake-in-one machine is a double-cavity structure to introduce the integrated cooking device, this is not intended to limit the scope of protection 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-bake-fryer, a steam-bake-in-one machine, etc. In addition, the double-cavity structure of the integrated cooking device including a steaming cavity and a baking cavity is only an exemplary description. Those skilled in the art can adjust the relative position between the two cavities (such as left and right, up and down, etc.), and can flexibly arrange the number and function of the cavities, such as the cavity including one steaming, one baking, one steaming and baking, one steaming and two baking, etc.

[0083] It should be noted that in the description of this application, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, it should not be understood as limiting this application. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0084] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "installed," "set," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0085] In addition, to better illustrate the present application, numerous specific details are provided in the following detailed description. Those skilled in the art will appreciate that the present application can be implemented without certain specific details. In some instances, gas stoves and other cooktops, as well as the principles of steaming / baking functions, which are well known to those skilled in the art, are not described in detail in order to highlight the main purpose of the present application.

[0086] The following will refer to the attached Figures 1 to 15At least a part of is used to describe the integrated cooking device of the present application.

[0087] Assuming that the dual-cavity steam-bake combination machine uses an independent steam-bake method, it is necessary to equip both the first cooking chamber corresponding to the steam-function cooking unit and the second cooking chamber corresponding to the baking function with a steam-generating device such as an evaporator. The structural form of adding an evaporator to the second cooking chamber will increase the cost of the equipment and, to a certain extent, increase the complexity of the water circuit corresponding to the steam supply. In addition, since the evaporator has a limited water storage capacity and is affected by many factors such as its heating principle and water replenishment logic, the steam-bake combination machine will inevitably encounter problems such as yellowing due to dry burning, water overflow due to excessive water replenishment, and scale formation in the evaporator during operation. As a result, when problems arise, both systems for the dual chambers need to be repaired, increasing maintenance costs. In addition, the configuration of two sets of evaporators and corresponding pipelines will also increase the size of the steam-bake combination machine. Therefore, in this application, the first and second cooking chambers are equipped with a single steam generating device (e.g., a steam generator), serving as the steam source for both chambers. Furthermore, corresponding piping and logic are configured for both chambers to achieve evaporation supply for both chambers. However, there is still room for improvement in steam piping and other related aspects.

[0088] In a possible embodiment, the integrated cooking device mainly includes a steam-bake machine 100 and a stove unit 200. For example, the stove unit 200 is arranged above the steam-bake machine 100. It can be installed in the kitchen in an embedded manner, and can better integrate with the decorative style and taste of the kitchen while effectively saving the installation space. For example, a fully embedded installation is adopted, that is, the cooktop of the stove unit is roughly flush with other parts (countertops), and the steam-bake machine is located in a cabinet below. The steam-bake machine mainly includes a cooking body 1, a first cooking unit corresponding to the steaming function (such as a steaming function cooking unit 2), a second cooking unit corresponding to the baking function (including a pure baking function and a baking function with the participation of the steaming function) (such as a baking function cooking unit 3), and a steam section 4 that releases steam as a cooking medium to both the first cooking unit and the second cooking unit. In this example, the cooking body is formed with two cooking chambers for holding ingredients to be cooked. That is, in this example, the steam-bake combination machine has a dual-cavity structure. For example, the cooking body 1 includes two inner pots corresponding to the first cooking unit and the second cooking unit, and the two inner pots are respectively formed with a first cooking chamber 11 and a second cooking chamber 12 corresponding to the first cooking unit and the second cooking unit. For example, a shelf can be provided in the inner pot, and the ingredients to be cooked can be placed directly on the shelf or placed on a container (such as a plate) placed on the shelf. Alternatively, a shelf structure such as a recessed structure or a rotatable plate can be provided on the inner side of the bottom of the inner pot, and the ingredients to be cooked can be placed directly on the shelf structure, or after the ingredients to be cooked are placed in the container, the bottom of the container can be placed in a position corresponding to the shelf structure. Since the realization of steaming and baking functions is closely related to the temperature of the cooking medium, heating components such as heating tubes can be set on the inner side of the top, inner side, and inner bottom of the inner pot, so that when necessary, the cooking medium in the cooking cavity (the hot air flow circulating in the second cooking cavity and / or the steam permeating the first / second cooking cavity) can be mainly heated or auxiliary / supplementary heated.

[0089] In one possible embodiment, the steam unit 4 primarily includes a steam generating device 41 and first and second steam pipelines communicating with the first and second cooking cavities. The steam generating device may be, for example, a steam pan or steam generator. For example, the steam generator is mounted on the back of the cooking unit (where the cooking unit is installed near the first cooking cavity) via a bracket 411 (e.g., a Z-shaped bracket). The steam generating device primarily includes a steam generating device body and a water storage container (e.g., a fresh water box). The steam generating device body forms a steam generating chamber and is equipped with steam generating heating components such as a heating pipe. The fresh water box is primarily used to supply water (steam generator) for steam generation to the steam generating chamber. For example, water is pumped into the steam generating chamber by a fresh water pump 42. The heating pipe heats the water in the steam generating chamber, thereby generating steam, which serves as the cooking medium. The steam pipeline is primarily used to distribute generated steam to the first cooking chamber and / or the second cooking chamber. This allows: the first cooking chamber, where the food to be cooked is located, to be filled with steam, thereby enabling the food to be cooked purely by steaming, according to a corresponding control program; and / or the second cooking chamber, where the food to be cooked is located, to be added with steam, thereby enabling the food to be cooked by methods such as steam grilling, according to a corresponding control program. A first steam dispensing port 431 corresponding to the first evaporation pipeline and a second steam dispensing port 432 corresponding to the second evaporation pipeline are positioned as close to the side walls of the cooking unit as possible to minimize the possibility of steam turbulence between different operating modes.

[0090] In one possible embodiment, the steam section 4 includes a water collection box 44, which is primarily used to collect water accumulated during the cooking process, high-humidity water vapor in the first cooking chamber, high-temperature, high-humidity gas in the second cooking chamber, and condensed water as described below. For example, the collection box can be equipped with a drainage pump, and the collected water can be discharged to a wastewater box, such as provided with the entire machine, through a drainage pump. The wastewater box can then be regularly cleaned and the accumulated water can be discarded. In this example, the water collection box 44 is mounted on the lower layer of the Z-shaped bracket, and the steam generator is mounted on the upper layer of the Z-shaped bracket. Obviously, those skilled in the art can select the specific form of the mounting structure based on actual needs, such as installing the two on two separate structures.

[0091] As in this example, a cavity is provided at the bottom of the cooking body, and both the clean water box and the waste water box are accommodated in the cavity at the bottom of the cooking body.

[0092] In addition to the first cooling duct at the top, the cooling fan assembly described below also features a vertical cooling duct on the back of the main cooking unit (the area between the backs of the two cooking units and the back of the main cooking unit housing). Because the back of the first cooking unit generates less heat than the second cooking unit, the steam generator and components requiring heat dissipation, such as the electronic control panel 16, can be located on the back of the main cooking unit, near the first cooking unit. Furthermore, the bellows body, front cover, and rear cover of the cooling fan can be made of plastic with sufficient temperature resistance. Injection molding can simplify the manufacturing process of the cooling fan assembly.

[0093] In this example, the electrical control panel is located below the heat dissipation fan assembly and on the back side away from the side corresponding to the grilling function cooking unit (along the width direction). The steam generator is located below the heat dissipation fan assembly and located near the steaming function cooking unit and the grilling function cooking unit (because steam needs to be released for the grilling function cooking unit at the same time). The water collection box is generally located below the electrical control panel, and the water pump is generally located below the steam generator. The cooking body is formed with two chambers below the water collection box and the steam generator, each of which contains a waste water box and a clean water box. Obviously, those skilled in the art can make appropriate adjustments to the arrangement positions of the components and the relative positions between the components, such as arranging the steam generator, water collection box, water pump, etc. in other integrated ways, arranging part of the electrical control panel at the top, etc.

[0094] In one possible embodiment, the grilling cooking unit 3 generally includes a fan cover assembly 31, which is mainly used to provide a circulating hot air flow into the second cooking cavity 12. For example, the fan cover assembly mainly includes a fan such as a centrifugal fan 311 (which can be called a uniform temperature fan) and heating components such as a heating coil. The uniform temperature fan is mainly used to ensure that the temperature of the hot air flow in the second cooking cavity is as uniform and consistent as possible. In order to reduce the operating temperature of the uniform temperature fan, an insulating structure such as thermal insulation cotton can be set between the uniform temperature fan and the second cooking cavity to effectively isolate the heat from the second cooking cavity from generating continuous heat radiation to the uniform temperature fan area. In this example, the fan cover assembly includes a fan cover 312, and the cooking body 1 includes a back plate. In this example, the cooking body 1 includes a back cover shell 14, which includes a back plate 141 and two side plates 142 extending forward from either side of the back plate. A hot air chamber is formed between the back plate 141 and the fan cover. A centrifugal fan is disposed in the hot air chamber. Heating components such as heating coils can be disposed in the hot air chamber or in other locations near the hot air chamber. For example, if the heating component is a heating coil, the heating coil can be disposed in the hot air chamber, and the centrifugal fan can be disposed in the area enclosed by the heating coil.

[0095] Obviously, those skilled in the art can determine the structural form of the fan cover / backplate, its location relative to the cooking unit, and the connection method between the two based on actual needs. For example, the backplate is a separate structure. In this example, the backplate is provided on the side of the cooking unit facing away from the user (e.g., the rear side). Obviously, the backplate can also be provided on other sides (e.g., the left or right side) in addition to the rear side. The fan cover and backplate can be connected to each other through methods such as snap-fitting, screwing, welding, etc., or they can be integrally formed.

[0096] Furthermore, the combination of the back plate and the fan cover is merely an exemplary description of how the hot air chamber is formed. Those skilled in the art can determine the specific form of the hot air chamber based on actual needs. For example, the fan cover is provided with a restraining structure that allows the aforementioned centrifugal fan to be installed in and removed from the hot air chamber. For example, the restraining structure includes a plurality of limit plates arranged along the circumference of the hot air chamber that can be pivoted open relative to the fan cover. In this way, it can be considered that the fan cover and the restraining structure form the hot air chamber, or it can be considered that the back plate and the fan cover with the additional restraining structure form the hot air chamber.

[0097] It should be noted that the hot air chamber referred to herein is not necessarily a complete chamber, but rather should be understood as a mounting location for the centrifugal fan and heating coil. Therefore, those skilled in the art can determine the structure and connectivity of the hot air chamber based on actual needs. For example, the centrifugal fan and heating coil can be located in the same chamber or separated into two connected chambers. The hot air chamber can be connected to the second cooking chamber via multiple connecting holes or by having a certain portion of the chamber open.

[0098] For example, the fan housing may be provided with a return air vent near the centrifugal fan, and also with supply air vents. For example, the supply air vents may be arranged approximately along the circumference of the return air vent or at locations along the circumference. For example, the centrifugal fan includes a motor and a fan. The motor rotates the fan facing the return air vent. The rotation of the fan causes air within the inner pot to flow through the return air vent and into the hot air chamber. In this example, the heating coil is positioned within the hot air chamber at a location corresponding to the return air vent, and the fan is positioned within the area enclosed by the heating coil. Thus, under the action of the fan, air within the inner pot flows through the return air vent and is drawn into the hot air chamber. There, it is heated by the heating tube, converting it into a heat-carrying hot air stream that serves as the cooking medium. The fan then propels the hot air stream toward the outer supply air vents and, from there, re-enters the inner pot. This cycle continuously distributes the hot air stream to the surface of the food to be cooked, thereby cooking the food in a hot air grilling manner through a corresponding control program.

[0099] In one possible embodiment, the cooking body 1 is provided with an openable (such as vertically / horizontally pivoted) door assembly on the operating side close to the user (such as the operating side is the side facing the user, which can usually be called the front side), such as one door assembly can be provided for each of the two inner pots, one door assembly can be shared by the two inner pots (such as the door assembly can be a rigid structure or can include two relatively movable door parts), one door assembly can be provided for each of the two inner pots and then a door assembly shared by the two can be added (two-layer door), etc. As 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.

[0100] Under normal circumstances, in order to ensure the performance of the integrated cooking equipment, the working environment of the door, power board, and related electrical components with temperature requirements (such as those arranged on the top and back of the cooking body) needs to be within a certain temperature. After the steaming cooking unit, the baking cooking unit and the stove assembly are combined, more heat may be generated in a limited space. In this way, it is necessary to perform more sufficient heat dissipation for the integrated cooking equipment. For example, the integrated steaming cooking unit and the baking cooking unit can certainly better meet the cooking needs of the user. For example, the user can use the dual-cavity synchronous operation method to achieve simultaneous steaming and baking cooking. However, since the units with different functions all involve heat sources during operation, when multiple functional modules are running, different heat sources may have cross- and superposition effects on each other, which will cause the equipment to have poor heat dissipation problems.

[0101] In one possible embodiment, the integrated cooking device includes a first heat dissipation part 5 arranged in the steam-bake combination machine, and the first heat dissipation part includes a first heat dissipation duct 51 and a heat dissipation fan assembly 52. As in this example, the first heat dissipation duct is arranged at the top of the cooking body, and the heat dissipation fan assembly is mainly used to draw air through the first heat dissipation duct to a position corresponding to the heat dissipation fan assembly and then discharge it, thereby dissipating heat to the aforementioned power board, electrical components, etc. to ensure their operational reliability.

[0102] Typically, the heat dissipation fan assembly is a cross-flow fan installed on the top of the cooking unit and connected to the first heat dissipation duct. However, a top-mounted design will somewhat limit the space available for expansion at the top of the inner pot. For example, it will significantly increase the height of the device and limit the space available for increasing the inner pot volume in the same direction. Therefore, in this application, the heat dissipation fan assembly is installed on the side of the cooking unit.

[0103] In this example, the heat dissipation fan assembly 52 is located on the back of the cooking unit. More specifically, in this example, the heat dissipation fan assembly is located on the back of the cooking unit, corresponding to the steam cooking unit. This reduces the height of the device, making it more compact and improving its integration.

[0104] In one possible embodiment, 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 body 5211, a first cover 5212 (such as a front cover) provided on the front side of the air box body, and a second cover 5213 (such as a rear cover) provided on the rear side of the air box body. A first heat dissipation chamber 5214 (such as a front heat dissipation chamber) is enclosed between the air box body and the front cover, and a second heat dissipation chamber 5215 (such as a rear heat dissipation chamber) is enclosed between the air box body and the rear cover. The first heat dissipation chamber 5214 and the second heat dissipation chamber 5215 are connected to each other, and the first heat dissipation fan 522 is installed in the heat dissipation air box. In this example, a portion of the first heat dissipation fan 52 is located in the front heat dissipation chamber and a portion is located in the rear heat dissipation chamber. Therefore, the two heat dissipation chambers can be connected by means of the installation of the first heat dissipation fan. For example, the first heat dissipation fan may be located in only one of the two heat dissipation chambers, and the two heat dissipation chambers may be connected to each other via a connecting structure such as a connecting hole.

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

[0106] In one possible embodiment, the heat dissipation bellows is provided with a first heat dissipation inlet 5216 at a location communicating with the first heat dissipation chamber, and a second heat dissipation inlet 5217 and a heat dissipation outlet 5218 at a location communicating with the second heat dissipation chamber. The first outlet side of the first heat dissipation duct can be connected to the first heat dissipation inlet, and the second heat dissipation inlet can be directly connected to the back space of the cooking body of the integrated cooking device. In this example, the first heat dissipation inlet and heat dissipation outlet are provided at the top of the heat dissipation bellows, and the second heat dissipation inlet is provided on the back side of the heat dissipation bellows.

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

[0108] In this way, along 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 (referred to as the first negative pressure zone / front negative pressure zone corresponding to the first heat dissipation chamber and the second negative pressure zone / rear negative pressure zone corresponding to the second heat dissipation chamber respectively).

[0109] In the first negative pressure zone, air entering the first heat dissipation duct through the first air inlet side of the first heat dissipation duct, under the guidance of the first heat dissipation fan, enters the first heat dissipation chamber through the first heat dissipation air inlet and is discharged through the heat dissipation air outlet. For example, the first heat dissipation air inlet and the first air outlet side of the first heat dissipation duct can be connected directly (e.g., by sleeve connection), indirectly connected through an intermediate pipe section, or aligned (e.g., without a connection).

[0110] The air in the back space of the cooking body heats up after cooling the components therein. In the second negative pressure zone, under the guidance of the first cooling fan, the heated air enters the second heat dissipation chamber through the second heat dissipation inlet and is then discharged through the heat dissipation outlet.

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

[0112] Obviously, the structural form, number, setting position and corresponding connection method of the first / second heat dissipation air inlet and 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 connected to the first / second heat dissipation chamber (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 method of the heat dissipation air outlet being directly connected to the first / second heat dissipation chamber may include but is not limited to the heat dissipation air outlet including two, the air inlet side of the heat dissipation air outlet being connected to the first / second heat dissipation chamber respectively, the heat dissipation air outlet including two branch pipes on the upstream side that are respectively connected to the first / second heat dissipation chamber and a main pipe on the downstream side that is respectively connected to the two branch pipes, etc.

[0113] In a possible embodiment, the first heat dissipation duct 51 covers the cooking units corresponding to the steaming function and the baking function at the same time 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 certain heat-generating component, the side of the cooking body, another first heat dissipation duct, a non-heat-generating area (that is, natural wind can be drawn into the first heat dissipation duct), etc.

[0114] In one possible embodiment, the first air inlet side 511 of the first cooling duct is located on the front side of the cooking unit, such as the front door frame of the cooking unit, while the first air outlet side 512 interfaces with the cooling air inlet of the first cooling duct assembly on the rear side. This allows the first cooling duct to span the width of the cooking unit across the two cooking units. The diagonally arranged cooling paths at the right front and left rear further extend the length of the first cooling duct, thereby potentially providing more efficient heat dissipation for the relevant components.

[0115] It should be noted that the diagonal arrangement mentioned here should be understood as 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.

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

[0117] It should be noted that the alignment of the heat dissipation area of the second door assembly to at least a certain extent mentioned here should mainly be understood as alignment in terms of orientation. Since the first and second door assemblies for the steaming / baking function cooking unit are arranged adjacent to each other, the heat dissipation fan assembly can not only dissipate heat for the second door assembly, but also take on a part of the heat dissipation for the first 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 to at least a certain extent with the heat dissipation area of the first and second door assemblies, 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.

[0118] In addition, under the guidance of a cross-flow fan set on the top of the cooking body, the air carrying heat is usually discharged forward from the door gap of the door assembly. The front row of heat dissipation 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.

[0119] In one possible embodiment, the integrated cooking device includes an exhaust structure that is arranged at an angle to 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°) to the horizontal direction. Exemplarily, it is discharged in a roughly 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, an upwardly extending heat dissipation exhaust duct 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.

[0120] For example, 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 stovetop portion of the stove unit, thereby switching the heat output from the front row to the upper row. For example, a range hood is usually provided above the stove unit (such as the top or side), and the exhaust air carrying heat can be promptly extracted by the range hood, thereby avoiding the resulting increase in the temperature of the indoor space. For example, the heat dissipation outlet can be connected to the stovetop portion of the stove unit by configuring a pipe, adding a connecting hole or other connecting structure on the stovetop portion, or directly aligning the heat dissipation outlet with at least a portion of the exhaust position (stove opening) on the stovetop portion of the stove unit.

[0121] In a possible embodiment, the cooking body is provided with an air outlet communication structure for exhaust and pressure relief corresponding to the steaming function cooking unit and the baking function cooking unit (respectively referred to as a first air outlet communication structure and a 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.

[0122] In this example, the first air outlet connecting structure and the second air outlet connecting structure include a connecting hole with a certain radial size (it can be understood that the radial size of the connecting hole is larger than the radial size of each single hole in the porous structure (mesh)). For example, the first air outlet connecting structure and the second air outlet connecting structure are respectively provided at the position corresponding to the back of the first / second cooking cavity of the cooking body, and two air intake connecting structures are provided at the corresponding position of the heat dissipation bellows (close to the wall of the first / second cooking cavity) (such as the first air intake connecting structure 52111 and the first air intake connecting structure 52112 respectively). In this way, when the heat dissipation bellows is in working state, the gas discharged from the first / second cooking cavity through the first / second air outlet connecting structure can be discharged upward together through the heat dissipation outlet. For example, the first / second air intake connecting structure can be connected with the aforementioned first heat dissipation cavity and / or second heat dissipation cavity (such as in this example, the first / second air intake connecting structure is connected with the position of the second heat dissipation cavity near the heat dissipation outlet). Similarly, the gas exhausted upward can be promptly extracted by the range hood on the top / side of the stove. However, unlike the air from the first heat dissipation duct mentioned above, the air from the first heat dissipation 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 chamber is exhausted and pressure relieved to ensure the cooking quality in the first / second cooking chamber. Since this part of the gas is a cooking medium, especially for the gas from the cooking chamber, it often contains oil stains and other costs, so discharging it in a timely manner can ensure the cleanliness of the indoor space. Of course, the cooking medium from the two cooking chambers also carries heat, so this treatment method can also prevent the indoor space from heating up.

[0123] Obviously, setting a pair of air outlet connecting structures close to the back of the cooking body is only a better implementation method. For example, only one air outlet connecting structure can be set on the back of the cooking body and the other can still be set on the top (connected to the first heat dissipation duct), both air outlet connecting structures can be set on the top, and the two air outlet connecting structures can be set non-closely (such as one connected to the back of the heat dissipation bellows, and the other connected to the side / top / bottom of the heat dissipation bellows, etc.).

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

[0125] In addition, for the first cooking chamber and the second cooking chamber during steam intervention, since some steam condenses during the exhaust process, a drainage structure (such as a drain port, drain pipe, etc.) 52113 is provided on the heat dissipation bellows, such as a drainage structure provided near the bottom of the heat dissipation bellows. Condensed water can be discharged through this drainage structure. In this example, the drainage structure has a drain port for connecting the pipe. Through the cooperation of the drainage connection structure such as a rubber hose and the connecting pipe, the condensed water can be drained to the aforementioned water collection box and further discharged to a waste water box or other structure / device capable of collecting condensed water, thereby ensuring the cleanliness of the equipment.

[0126] As in this example, the bellows body includes a vertically arranged partition, and the outer edge of the partition extends toward the first heat dissipation chamber and the second heat dissipation chamber with a first flange and a second flange respectively. The first flange, the partition and the front cover form the first heat dissipation chamber, and the second flange, the partition and the rear cover form the second heat dissipation chamber. The drainage structure is arranged in the second heat dissipation chamber corresponding to the heat dissipation outlet, such as a drainage structure is arranged at the bottom of the second flange, such as the drainage structure is a drainage outlet with a connecting pipe section extending below (outside the bottom of the bellows body). In order to ensure that the condensed water can be better gathered, the bottom wall of the heat dissipation bellows can be lower than other positions corresponding to the height of the drainage structure. For example, the bottom wall of the heat dissipation bellows is set to a structure that gathers toward the drainage structure (such as a curved structure, an inclined structure, etc.).

[0127] Since gas condensation is more likely to occur near the heat dissipation outlet, the drainage structure is set in the second heat dissipation chamber that is directly connected to the heat dissipation outlet. Therefore, the setting position of the drainage outlet can be flexibly adjusted according to the adjustment method of the heat dissipation outlet. Of course, the drainage structure can also be set in the first heat dissipation chamber.

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

[0129] In one possible embodiment, a drainage structure may be provided on the heat dissipation bellows. For example, condensed water generated within the heat dissipation bellows can flow through the drainage structure to a location corresponding to the aforementioned drainage structure and / or back to the first / second cooking chamber. For example, the drainage structure may include a guide plate, a guide groove, a trumpet-shaped guide pipe, etc. Drainage structures may be provided separately for the first and second cooking chambers, or one or more drainage structures may be provided in a non-targeted manner, focusing solely on the angle at which condensed water is generated within the heat dissipation bellows. Exemplarily, the drainage structure is a downwardly inclined flat / curved guide plate disposed along the width of the heat dissipation bellows, allowing condensed water to flow through the guide plate to the drainage structure at the bottom.

[0130] In this example, the drainage structure includes a first drainage structure 52114 corresponding to the first cooking cavity and a second drainage structure 52115 corresponding to the second cooking cavity. For example, the first and second drainage structures are guide grooves and have substantially identical structures. Furthermore, in this example, the first and second drainage structures are located at positions corresponding to the aforementioned first and second air inlet communication structures. This allows condensed water generated within the heat dissipation bellows to flow back into the first and second cooking cavities via the first and second drainage structures, the first and second air inlet communication structures, and the first and second air outlet communication structures. This can be a full or partial return (e.g., a portion flowing back to the first and second cooking cavities and a portion directed to the drainage structure).

[0131] In one possible embodiment, the first / second air outlet connecting structure and the first / second air inlet connecting structure are arranged at a position near the top of the back of the heat dissipation air box. In this way, taking full reflux as an example, in the process of realizing condensed water collection, the first level of condensed water recovery can be performed through the first / second drainage structure, that is, the first condensed water recovery structure returns the recovered condensed water to the first / second cooking chamber. The second level of condensed water recovery can be performed through the drainage structure, that is, the second condensed water recovery structure discharges the recovered condensed water to a condensed water collection structure such as a waste water box (for example, in the case of partial reflux, the second condensed water recovery structure can serve as a supplement to the first condensed water recovery structure, and can supplement and recover part of the condensed water collected by the first / second drainage structure but not returned to the first / second cooking chamber). In order to realize full reflux, the guide groove can be set to be inclined toward the cooking chamber.

[0132] Obviously, the first and second air guide structures are substantially identical, and their alignment and communication with the first and second air inlet communication structures is merely an exemplary description. Those skilled in the art may flexibly select the structural form of the first and second air guide structures and the method for achieving reverse flow based on actual needs. For example, the structural form of the first and second air guide structures and the method for achieving reverse flow may also differ. For example, the first and second air guide structures are inclined guide plates, the lowest point of which communicates with the first or second cooking chamber via a communication structure such as a communication hole or a communication tube.

[0133] In this example, a heat dissipation bellows is disposed at the back of the cooking unit. The bellows is generally a volute-shaped structure. Viewed along the width of the back of the cooking unit, the bellows comprises a first bellows portion and a second bellows portion. The first bellows portion is provided with a first heat dissipation inlet at the top, a second heat dissipation inlet at the back, and a heat dissipation outlet at the top of the second bellows portion. A first heat dissipation fan is disposed in the first bellows portion, while the second bellows portion is located approximately near the middle of the cooking unit. The first air intake / intake connecting structure is disposed near the first and second cooking chambers, respectively. This allows for a more compact heat dissipation fan assembly. Clearly, those skilled in the art can flexibly adjust the structure of the heat dissipation bellows, the structures of the first and second bellows portions, and the locations of the first and second heat dissipation inlets and outlets to suit specific needs. For example, the heat dissipation outlet can be widened or extended to create a new heat dissipation outlet path, or the second air intake connecting structure can be located near the middle of the second cooking chamber.

[0134] In one possible embodiment, the integrated cooking device includes a second heat dissipation portion 8 disposed on a cooker unit 200. For example, the cooker unit 200 primarily includes a cooker housing 6 having two cooker mounting positions, each of which is provided with two cookers 7. The second heat dissipation portion 8 is disposed within the cooker housing. Obviously, those skilled in the art can determine the structure and number of the cooker mounting positions, as well as the distribution of the respective cooker mounting positions (if multiple cookers are provided) on the cooktop based on actual needs.

[0135] In one possible embodiment, the second heat dissipation portion 8 primarily includes a second heat dissipation duct 81 and a second heat dissipation fan 82. For example, the second heat dissipation fan 82 has a second air inlet side and a second air outlet side. If the second heat dissipation fan is a cross-flow fan, the cross-flow fan's air inlet communicates with the environment within the range housing, the cross-flow fan's air outlet communicates with the second air inlet side of the second heat dissipation duct, and the second air outlet side of the second heat dissipation duct communicates with the external environment. In this way, the cross-flow fan can promptly cool heat-generating components such as electronic components within the range housing.

[0136] In one possible embodiment, the air inlet of the crossflow fan is located on the side of the cooktop closest to the operator (e.g., the front side), the air outlet of the crossflow fan is located on the side of the cooktop away from the operator (e.g., the rear side), and the second air outlet side of the second heat dissipation duct is located on the side of the cooktop away from the operator. It will be appreciated that, similar to the aforementioned first heat dissipation portion, those skilled in the art can determine how the air outlet side of the second heat dissipation duct communicates with the external environment based on actual needs, such as by leveraging the existing structure of the cooktop or by adding structures / components such as communication ports or ducts.

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

[0138] On the one hand, those skilled in the art can determine the structural form of the exhaust structure based on actual needs, such as an exhaust duct, exhaust port, exhaust hood, etc. On the other hand, it is obvious that the exhaust structure does not have to be located near the rear side of the stove unit. In other words, as long as exhaust is feasible, those skilled in the art can also adjust the exhaust position of the exhaust structure.

[0139] Furthermore, sharing a common exhaust structure for both is merely a preferred embodiment. Those skilled in the art can configure two independent exhaust structures based on actual needs, and the exhaust locations of the two exhaust structures can be the same or different. Examples include, but are not limited to: an exhaust structure comprising a main pipe and two branch pipes extending from the main pipe, the two branch pipes respectively connected to the exhaust locations of the first and second cooling air ducts; and an exhaust structure comprising two closely spaced exhaust pipes, both of which communicate directly with the external environment or communicate with the external environment through a common exhaust port.

[0140] In one possible embodiment, an exhaust area 61 is provided on the cooktop (the upper surface of the cooktop) of the cooktop housing 6 as a common exhaust structure. For example, the exhaust area may include an open structure, exhaust holes, or an exhaust mesh. For example, a range hood disposed on the side or above the cooktop can promptly extract the gas delivered to the exhaust area 61. Thus, in this embodiment, three types of heat-carrying gases can be discharged through the exhaust area 61: heat-carrying gas from the first heat dissipation duct (primarily used to cool the door assembly and top heat-generating components of the steam-bake combination unit), cooking medium from the first / second cooking chamber (primarily used to relieve pressure and exhaust to ensure cooking reliability of the steam-bake combination unit), and heat-carrying gas from the second heat dissipation duct (primarily used to cool the heat-generating components inside the cooktop unit).

[0141] In a possible embodiment, in order to ensure that the exhaust area 61 of the stove surface can be better connected with the heat dissipation 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. The exhaust connection structure 62 can be a corrugated pipe, a rigid pipe, a baffle, etc.

[0142] As can be seen, in a preferred embodiment of the present application, by placing the heat dissipation fan assembly on the back of the cooking unit and employing a vertical centrifugal fan, space at the top of the inner pot is effectively freed up. This not only increases the inner pot's volume in the vertical direction, but also reduces the device's height, as evidenced by a reduction in the height of the top of the front door frame of the cooking unit. By configuring the heat dissipation bellows with dual heat dissipation chambers / air inlets, the integrated cooking device can be effectively cooled through dual air inlets from a single location. By locating the evaporator, heat dissipation fan assembly, and electronic control panel on the side (back) of the cooking unit, close to the first cooking cavity corresponding to the steaming function, the corresponding installation structure can be kept at a relatively low temperature. By integrating heat dissipation and exhaust pressure relief structures for both cooking cavities into the heat dissipation bellows, the cooking medium, which is used to ensure cooking reliability, can be discharged along with the heat dissipation air. In other words, the first heat dissipation fan, located on the back of the cooking unit, not only dissipates heat for the door assembly and related structures on the top / side, but also provides a path for the pressure relief air, thereby ensuring cooking reliability. By converging the exhaust point (heat dissipation outlet) of the first heat dissipation section with the exhaust point (second exhaust side) of the second heat dissipation section and connecting them to the exhaust area on the cooktop assembly, heat dissipation gases from the steam-bake combination and cooktop assembly, as well as cooking medium released from the steam-bake combination, can be centrally discharged, improving the device's integration. Simultaneously, the exhaust area corresponding to the first heat dissipation duct can be switched from front exhaust to top exhaust, preventing heat from being directly sprayed onto the user's body (e.g., roughly the user's legs), thereby improving the user experience.

[0143] Thus far, the technical solutions of the present application have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present application.
