Description

Technical Field

[0001] This application relates to the technical field of kitchen electrical appliances, and particularly relates to an integrated built-in cooking device and its cooling fan assembly. For example, the integrated built-in cooking device of this application has a higher integration degree on the premise of having multiple functions such as cooking on a stove, steaming, and roasting, and can achieve the overall full-embedded / built-in installation of the device while saving the space of installation scenarios such as the kitchen as much as possible. 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 a 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 form of kitchen electrical appliances is: using a steamer to cook ingredients by steaming, and using an oven to cook ingredients by roasting. With the refined development of kitchen electrical 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 medium between the two, there has emerged a steam oven with both steaming and roasting functions (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, a steam oven with a certain integration degree can also meet this demand of users. In addition, in adaptation to the currently relatively common built-in installation, there have also emerged combined devices such as steam oven with frying function, and a combination device of a steam oven and a cooking appliance unit such as a gas stove.

[0003] Taking the combined device of a steam oven and gas stove and other cooking units as an example, for the steam oven, the cooking media for the two cooking methods of steaming and baking are steam and hot air flow (which may also contain steam) respectively. Therefore, there must be a heat dissipation requirement during the cooking process. For example, heat dissipation is required for the door assembly (such as the steam and hot air flow radiate heat to the door assembly, causing its temperature to rise. Since the door assembly is close to the user, considering the use safety, heat dissipation for the door assembly is needed). In addition, there are also related structures and components that need to be cooled, such as those located at the top, side, etc. inside the cooking device. Taking the components as an example, the working reliability of the components is affected by temperature (for example, on the one hand, the components themselves are heat sources, so they will heat up due to being in a long-term working state. On the other hand, the steam and hot air flow radiate heat to the top of the inner container where the components are located, etc., which will also cause their temperature to rise). For the gas stove, the part close to the cooking appliance belongs to the heat radiation area, and the components that need to be cooled inside it are also heat-generating components. Since the cooking device has multiple functions, the amount of heat to be dissipated will increase. Due to the certain degree of integration of the cooking device itself, various heat quantities may be superimposed and interfered with each other. In this way, there is quite a lot of room for improvement in how to effectively dissipate heat from the cooking device. Summary of the Invention

[0004] This application aims to at least partly solve the above technical problems and / or at least partly solve some of the above technical problems. Specifically, how to improve the integration degree of the device as much as possible while dissipating heat from an integrated built-in cooking device with multiple functions.

[0005] In view of this, this application provides an integrated built-in 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; and a cooking appliance unit, which includes a stove shell and a second heat dissipation part, and the second heat dissipation part includes a second heat dissipation fan and a second heat dissipation air duct; wherein, the stove shell includes a bottom shell and a stove top arranged on the bottom shell, an air intake area is arranged on the bottom shell, and an exhaust area is arranged on the stove top. At least a part of the gas from the air outlet and the gas entering the second heat dissipation air duct through the air intake area can reach the exhaust area; wherein, an electronic control board is arranged inside the stove shell, at least a part of the electronic control board is located between the air intake area and the air inlet of the second heat dissipation fan, and the second heat dissipation air duct is located between the air outlet of the second heat dissipation fan and the exhaust area.

[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, thus ensuring the heat dissipation performance of the integrated cooking device. Moreover, since the exhaust path has a certain crossover portion in the part closer to the downstream side of the two units, 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. Since the exhaust area is located on the stove top, it is possible to effectively avoid the phenomenon that the heat is directly sprayed onto the user's body due to the forward exhaust of the cooking unit, enhancing the user experience. For example, the electronic control board may include the electronic control part related to the stove unit or the electronic control part related to the cooking unit. It should be noted that the electronic control board here corresponds to the second electronic control board in the specific embodiment.

[0007] For the above-mentioned integrated built-in cooking device, in a possible implementation manner, the stove unit includes a stove, and a stove installation position and / or a knob and / or an interaction area are provided on the stove top, and the stove can be installed at the position on the stove top corresponding to the stove installation position; and / or a first installation area, a second installation area and a communication area are provided on the bottom shell, the electronic control board is arranged at the position on the bottom shell corresponding to the first installation area, the second heat dissipation fan is arranged at the position on the bottom shell corresponding to the second installation area, and the air outlet of the heat dissipation fan assembly is communicated with the exhaust area through the communication area.

[0008] With such a configuration, a possible structural form of the stove shell is given. For example, the interaction area can achieve corresponding interaction operations through forms such as an operation panel, buttons, and switches, and the structural forms, relative positions, etc. of the first / second installation areas can be flexibly set according to actual needs.

[0009] For the above-mentioned integrated built-in cooking device, in a possible implementation manner, the device includes a cooking main body, and the heat dissipation fan assembly includes: a first heat dissipation air duct, which is arranged in the cooking main body; a heat dissipation air box, which is arranged in the cooking main body and includes an air outlet, 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 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.

[0010] With such a configuration, it is possible to seek to better meet the heat dissipation requirements of the device by means of two-way air intake. Specifically, by collecting the heat dissipation media from the first air inlet and the second air inlet through the same heat dissipation fan assembly and discharging them centrally, the integration degree of the cooking device is improved. It should be noted that the first air inlet and the second air inlet here correspond to the first heat dissipation air inlet and the second heat dissipation air inlet in the specific embodiment.

[0011] It should be noted that the installation space for the cooking main body here should be understood as follows: The cooking main body includes an outer shell, an installation space is formed inside the shell, and the installation space houses an inner container forming a cooking chamber, as well as related structures such as a first heat dissipation air duct, components, and a heat dissipation fan assembly disposed outside it. There is a certain margin between the installation space and these structures housed therein. The second air inlet is mainly used to meet the heat dissipation requirements of the surfaces of the structures housed therein and the parts close to the surfaces, such as the installation space in the side, bottom, and other orientations.

[0012] For the above integrated built-in cooking device, in a possible implementation manner, the cooking main body includes an evaporation part and at least one cooking chamber.

[0013] The heat dissipation air box includes an air inlet connection structure, and the gas in the at least one cooking chamber can enter the heat dissipation air box through the air inlet connection structure and be discharged through the air outlet.

[0014] With such a configuration, it is possible to seek to improve the integration degree of the device and ensure the operation reliability of the cooking device. Specifically, while the first heat dissipation fan realizes the heat dissipation performance through the cooperation of the first / second air inlets and the air outlet, the gas from the cooking chamber is collected and further discharged, thereby ensuring the reliability of the cooking device. For example, the air inlet connection structure can be in a state of being connected or not connected to the heat dissipation air duct according to the pressure in the cooking chamber.

[0015] It can be understood that those skilled in the art can determine the switching method of the connection state between the air inlet connection structure and the heat dissipation air box 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 air inlet connection structure, 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 air inlet connection structure, 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 movement of the plugging structure makes the air inlet connection structure in a state of being connected to the heat dissipation air box and thus allows part of the cooking medium to be discharged.

[0016] For the above integrated built-in cooking device, in a possible implementation manner, the cooking main body includes a door body assembly disposed in the cooking chamber, and the first heat dissipation air duct includes an air inlet side, and the heat from the door body assembly can enter the first heat dissipation air duct through the air inlet side.

[0017] With such a configuration, it is possible to seek to cool the door body assembly to a certain extent through the heat dissipation air duct.

[0018] It is understandable that those skilled in the art can determine the implementation manner in which the heat from the door body assembly can enter the heat dissipation air duct through the air inlet side according to actual needs. For example, the air inlet side can be arranged near the door body assembly, and the air inlet side is at least partially aligned with the heat dissipation opening on the door body assembly. It should be noted that the air inlet side here corresponds to the first air inlet side in the specific implementation manner.

[0019] For the above integrated built-in cooking device, in a possible implementation manner, the cooking main body includes an evaporation part, and at least a part of the evaporation part is arranged on the side part of the cooking main body.

[0020] With such a structure, it is possible to seek to improve the integration degree of the cooking device. For example, the cooking chamber includes a pure steaming function cooking chamber and a baking function cooking chamber that allows steam to participate (in the tender baking mode), and the evaporation part is arranged on the side part close to the steaming function cooking chamber with a lower temperature.

[0021] In a possible implementation manner, the heat dissipation air box is provided with a drainage structure, and the drainage structure can guide the liquid in the heat dissipation air box to the cooking chamber and / or a position where the heat dissipation air box can drain water. With such a structure, it is possible to seek to timely drain the condensed water generated in the heat dissipation air box, thereby ensuring the cleanliness of the integrated built-in cooking device.

[0022] For the above integrated built-in cooking device, in a possible implementation manner, the heat dissipation air box includes a first heat dissipation chamber and a second heat dissipation chamber that communicate with each other. Among them, the first air inlet and the second air inlet are respectively arranged at positions of the heat dissipation air box corresponding to the first heat dissipation chamber and the second heat dissipation chamber; and / or

[0023] The air outlet is directly communicated with the first heat dissipation chamber and / or the second heat dissipation chamber.

[0024] With such a structure, it is possible to seek to effectively dissipate the heat of the device through the dual-chamber air inlet method.

[0025] For the above integrated built-in cooking device, in a possible implementation manner, the second heat dissipation fan is a cross-flow fan; and / or the air intake area is arranged on the side of the bottom shell close to the operator; and / or the knob is arranged on the side of the bottom shell close to the operator; and / or the interaction area is arranged on the side of the bottom shell close to the operator; and / or the exhaust area is arranged at a position on the cooking surface far from the operator; and / or the exhaust area is provided with an exhaust cover plate having a communication structure.

[0026] With such a structure, a possible structural form of the cooking shell is given.

[0027] For the above integrated built-in cooking device, in a possible implementation manner, at least a part of the heat dissipation fan assembly is disposed on the side of the cooking main body.

[0028] With such a configuration, it is possible to seek to improve the integration degree of the integrated cooking device in the height direction. For example, the height of the device can be reduced and / or the volume of the cooking chamber can be increased in the height direction.

[0029] For the above integrated built-in cooking device, in a possible implementation manner, the cooktop unit is disposed above the cooking unit, and the gas in the heat dissipation air box is discharged to the external environment substantially in the vertical direction via the air outlet and the exhaust area.

[0030] With such a configuration, a specific combination manner of the three functions of the stove, steaming, and baking and their exhaust orientations are given. Description of the Drawings

[0080] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application. For example, although this embodiment is described in combination with an integrated steam and grill oven including a steam function and a baking (including hot air baking and steam baking) function, and a cooking appliance assembly (in this example, the cooking appliance assembly includes two cooking appliance units) all arranged above the double-chamber steam and grill oven, and the steam and grill oven is of a double-chamber structure to introduce the integrated built-in cooking device, this is not intended to limit the protection scope of the present application. Without departing from the principle of the present application, those skilled in the art can apply the present application to other application scenarios, such as a steam, grill and fry integrated oven, a steam and grill oven, etc. In addition, the double-chamber structure including a steam chamber and a baking chamber in the integrated built-in cooking device is only an exemplary description. Those skilled in the art can adjust the relative positions between the two chambers (such as left and right, up and down, etc.), and can flexibly arrange the number, functions, etc. of the chambers, such as the chambers including one steam, one baking, one steam and baking, one steam and two bakings, etc.

[0081] It should be noted that in the description of the present 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 the 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, and therefore cannot be understood as a limitation to the present application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0082] In addition, it should also be noted that in the description of the present application, unless otherwise clearly specified and limited, the terms "installation", "setting", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can also be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0083] In addition, in order to better illustrate the present application, numerous specific details are given in the following specific embodiments. Those skilled in the art should understand that the present application can also be implemented without some specific details. In some instances, details of well-known cooking appliances such as gas stoves and the principles of steam / baking functions are not described in detail in order to highlight the gist of the present application.

[0084] The integrated built-in cooking device of the present application will be described below with reference to at least a part of Figures 1 to 17 the accompanying drawings.

[0085] If the double cavity in the steam and convection oven adopts the independent steam and convection mode, it is necessary to configure steam generating devices such as evaporation trays for both the first cooking cavity corresponding to the steam function cooking unit and the second cooking cavity corresponding to the convection function cooking unit. Among them, the structural form of adding an evaporation tray to the second cooking cavity will increase the cost of the equipment and will also increase the complexity of the water circuit corresponding to the steam supply to a certain extent. In addition, due to the limited water storage capacity of the evaporation tray and the influence of various factors such as its heating principle and water replenishment logic, during the operation of the steam and convection oven, problems such as yellowing due to dry burning, water overflow due to excessive water replenishment, and scale formation in the evaporation tray will inevitably occur. In this way, in the case of problems, it is necessary to perform maintenance operations on the two sets of systems for the double cavity, increasing the maintenance cost. In addition, the configuration of the two evaporation trays and the corresponding pipelines will also increase the volume of the steam and convection oven. Therefore, in this application, first, the same steam generating device (such as a steam generator) is configured for the first cooking cavity and the second cooking cavity, that is, the same steam generating device is used as the steam source for the double cavity. On this basis, by configuring the corresponding pipelines, logic, etc. for the double cavity, the evaporation supply for the double cavity is realized. In this way, there is still a certain room for improvement in related links such as the steam pipeline.

[0086] In a possible implementation, the integrated built-in cooking device mainly includes a steam and convection oven 100 and a cooktop unit 200. For example, the cooktop unit 200 is disposed above the steam and convection oven 100. It can be installed in the kitchen in an embedded manner, effectively saving installation space while better integrating with the kitchen's decorative style and tone. Exemplarily, a full-embedded installation is adopted, that is, the cooktop surface of the cooktop 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 is formed with two cooking chambers for holding the ingredients to be cooked. That is, in this example, the steam and convection oven has a double-chamber structure. For example, the cooking main body 1 includes two inner liners corresponding to the first cooking unit and the second cooking unit, and the two inner liners 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 inside the inner liner, and the ingredients to be cooked can be directly placed on the shelf or in a container (such as a plate) placed on the shelf. Or a placing structure such as a concave structure or a rotatable plate is provided on the inner side of the bottom of the inner liner. The ingredients to be cooked can be directly placed on the placing structure or, after the ingredients to be cooked are placed in a container, the bottom of the container can be placed at a position corresponding to the placing structure. Since the realization of the steaming and baking functions is closely related to the temperature of the cooking medium, heating components such as heating tubes can be provided at positions such as the inner side of the top, the inner side of the side, and the inner side of the bottom of the inner liner, so that in case of need, the cooking medium in the cooking chamber (the hot air flow circulating in the second cooking chamber and / or the steam diffused in the first / second cooking chamber) can be mainly heated or supplemented / auxiliary heated.

[0087] 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. For example, the steam generator is disposed on the back of the cooking main body (at a position of the installation space of the cooking main body close to the first cooking chamber) through 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 vessel (such as a clean water box, etc.). The steam generating device body forms a steam generating chamber and is configured with steam generating heating components such as heating tubes. The clean 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 clean 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. A first steam discharge port 431 corresponding to the first evaporation pipeline and a second steam discharge port 432 corresponding to the second evaporation pipeline, and the two steam discharge ports are preferably disposed at positions close to the two side walls of the cooking main body to minimize the probability of steam turbulence occurring between different working modes.

[0088] 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 collected water can be discharged 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.

[0089] In this example, a chamber is provided at the bottom of the cooking main body, and both the clean water box and the waste water box are accommodated in the chamber at the bottom of the cooking main body.

[0090] 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 first electronic control board 161 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.

[0091] In this example, the electronic control board is located below the heat dissipation fan assembly and on the side away from the cooking unit corresponding to the baking function (in the width direction) at the back. The steam generator is located below the heat dissipation fan assembly and at a position on the steaming function cooking unit close to the baking function cooking unit (because steam needs to be supplied to the baking function cooking unit simultaneously). The water collection box is 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, 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.

[0092] 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 centrifugal fan 311 and other fans (such as 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 in 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.

[0093] Obviously, those skilled in the art can determine the structural form of the blower housing / back plate, its installation position relative to the cooking main body, the connection method between the two, etc. according to actual needs. Exemplarily, the back plate is a separate structure, etc. In this example, the cooking main body is provided with the aforementioned back plate on the side away from the user (such as the rear side). Obviously, in addition to the rear side, the back plate can also be provided on other side parts (such as the left side, the right side). The blower housing 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.

[0094] In addition, the combination of the back plate and the blower housing is only an exemplary description of forming the hot air chamber. Those skilled in the art can determine the specific form of the hot air chamber according to actual needs. Exemplarily, a restraining structure is provided on the blower housing 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 circumferentially along the hot air chamber and pivotally openable relative to the blower housing. In this way, it can be considered that the blower housing and the restraining structure form the hot air chamber, or it can also be considered that the back plate and the blower housing with the added restraining structure form the hot air chamber.

[0095] It should be noted that the so-called hot air chamber is not necessarily an absolutely 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 multiple communication holes, or can also achieve its connection with the second cooking chamber by setting a certain part as an open structure.

[0096] For example, the blower housing is provided with an air return port near the centrifugal blower, and the blower housing is also provided with an air supply port, such as the air supply port is arranged approximately circumferentially around the air return port or at a local position of the circumferential direction. 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 tank through the air return port into the hot air chamber. In this example, the heating coil is arranged 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 tank flows through the air return port and is sucked into the hot air chamber, and then is heated by the heating pipe to be converted into a hot air flow carrying heat and serving as a cooking medium. In this way, the hot air flow is thrown to the peripheral air supply port by the blower and then sent into the inner tank again. By circulating in this way, the hot air flow can be continuously emitted to the surface of the food to be cooked, so as to cook the food to be cooked in the way of hot air roasting through the corresponding control program.

[0097] In a possible implementation, the cooking main body 1 is provided with a door assembly on the operation side close to the user (for example, if the operation side is the side facing the user, it is usually called the front side), and the door assembly can be opened (for example, pivoted and opened vertically / horizontally). For example, one door assembly can be configured for each of the two inner liners, or two inner liners share one door assembly (for example, the door assembly can be a rigid structure or can 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.

[0098] Under normal circumstances, in order to ensure the performance of the integrated built-in cooking device, the working environments of the door, the power board, and related electrical components with temperature requirements (such as those arranged 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 stove component, more heat may be generated in the limited space. In this way, more sufficient heat dissipation is required for the integrated built-in 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 units with different functions involve heat sources during operation, when multiple functional modules are operating, there may be mutual influences such as cross and superposition between different heat sources, which will lead to problems such as poor heat dissipation of the device.

[0099] In a possible implementation, the integrated built-in cooking device includes a first heat dissipation part 5 arranged in the steam and convection oven, and the first heat dissipation part includes a first heat dissipation air duct 51 and a heat dissipation fan assembly 52. In this example, the first heat dissipation air duct is arranged 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.

[0100] Under normal circumstances, the heat dissipation fan assembly is a cross-flow fan arranged on the top of the cooking main body and communicated with the first heat dissipation air duct. However, the top-mounted structure will affect the expansion space at the top of the inner liner to a certain extent. For example, it will significantly increase the size of the device in the height direction and limit the increased space of the inner liner volume in the height direction. Therefore, in this application, the heat dissipation fan assembly is arranged on the side of the cooking main body.

[0101] As in this example, the cooling fan assembly 52 is disposed on the back side of the cooking main body. More specifically, in this example, the cooling fan assembly is disposed at a position on the back side of the cooking main body corresponding to the steaming function cooking unit. In this way, the size of the device in the height direction is reduced, making the device more compact, thereby improving the integration of the device to a certain extent.

[0102] In a possible implementation manner, the cooling fan assembly 52 mainly includes a cooling air box 521 and a first cooling fan 522. For example, if the first cooling fan is a centrifugal fan, the cooling air box 521 mainly includes an air box main body 5211, a first cover body 5212 (which can be called a front cover body for example) disposed on the front side of the air box main body, and a second cover body 5213 (which can be called a rear cover body for example) disposed on the rear side of the air box main body. A first cooling chamber 5214 (which can be called a front cooling chamber for example) is defined between the air box main body and the front cover body, and a second cooling chamber 5215 (which can be called a rear cooling chamber for example) is defined between the air box main body and the rear cover body. The first cooling chamber 5214 and the second cooling chamber 5215 communicate with each other, and the first cooling fan 522 is installed in the cooling air box. As in this example, a part of the first cooling fan 52 is in the front cooling chamber and a part is in the rear cooling chamber, so the two cooling chambers can communicate with each other by virtue of the installation of the first cooling fan. It can also be that the first cooling fan is only in one of the two cooling chambers, and the two cooling chambers communicate with each other through a communication structure such as a communication hole.

[0103] Obviously, the combination of the front and rear cover plates and the air box main body is only an exemplary composition form of the cooling air box. For example, the front cover plate can be replaced by the rear wall of the inner liner or the two (the front cover plate and the rear wall of the inner liner) can be integrally formed, that is, the cooling air box and the rear wall of the inner liner form a cooling 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.

[0104] In a possible implementation manner, the cooling air box is provided with a first cooling air inlet 5216 at a position communicating with the first cooling chamber, and a second cooling air inlet 5217 and a cooling air outlet 5218 at a position communicating with the second cooling chamber. The first air outlet side of the first cooling air duct can be connected to the first cooling air inlet, and the second cooling air inlet can be directly connected to the back side space of the cooking main body of the integrated built-in cooking device. As in this example, the first cooling air inlet and the cooling air outlet are disposed at the top of the cooling air box, and the second cooling air inlet is disposed on the back side of the cooling air box.

[0105] 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.

[0106] 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 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).

[0107] 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 docked through direct connection (such as socket connection), indirect connection through an intermediate pipe section, alignment (such as no connection relationship can be generated), etc.

[0108] 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.

[0109] 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 built-in 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 directly integrated built-in cooking device can be cooled.

[0110] Obviously, the structural forms, numbers, installation positions, and corresponding connection methods of the first / second heat dissipation air inlets and the heat dissipation air outlet are only an exemplary description, and those skilled in the art can flexibly adjust them according to actual needs. For example, the heat dissipation air outlet can be directly 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 the heat dissipation air outlet including two, the air inlet side of the heat dissipation air outlet being respectively connected to the first / second heat dissipation chambers, the heat dissipation air outlet including two upstream branches respectively connected to the first / second heat dissipation chambers and a downstream main pipe respectively connected to the two branches, etc.

[0111] 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. Therefore, 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 sucking natural wind into the first heat dissipation air duct), etc.

[0112] 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 from the upper right front to the lower 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.

[0113] It should be noted that the so-called diagonal arrangement should be understood as that after the arrangement direction in the front-rear direction is roughly determined, the first air inlet side and the first air outlet side are staggeredly arranged to a certain extent in the left-right direction, so as to appropriately lengthen the length of the first heat dissipation air duct.

[0114] In a possible implementation, the first air inlet side of the first heat dissipation air duct is located in the heat dissipation area (such as a heat dissipation port is provided in the heat dissipation area) 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 area, it can also share at least a part of the heat dissipation for the second door body assembly.

[0115] It should be noted that the so-called at least somewhat aligned with the heat dissipation area 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 a part of the heat dissipation for the first door body assembly. Preferably, in order to better dissipate the mechanical energy heat from the first door body assembly, 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 areas 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.

[0116] 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.

[0117] In a possible embodiment, the integrated embedded cooking device includes an exhaust structure that is arranged in a manner that has 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 embedded cooking device. For example, the heat dissipation exhaust structure can be a heat dissipation exhaust port, a heat dissipation exhaust duct that extends upward and is connected to the heat dissipation outlet, a structure that is 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), and thus connected to the outdoor environment, etc.

[0118] 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.

[0119] 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.

[0120] 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 of the heat dissipation air box (close to the walls of the first / second cooking chambers). In this way, when the heat dissipation air box is in a working state, the gas discharged from the first / second cooking chambers through the first / second air outlet connection structures can be discharged upward together through the heat dissipation air outlet. For example, the first / second air inlet connection structures can communicate with the aforementioned first heat dissipation chamber and / or the second heat dissipation chamber (in this example, the first / second air inlet connection structures communicate with the positions of the second heat dissipation chamber close to the heat dissipation air outlet). Similarly, the gas discharged upward can be timely extracted 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 exhaust and pressure relief. 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. Therefore, 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. Therefore, such a treatment method can also avoid the indoor space from heating up at the same time.

[0121] 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.).

[0122] Compared with the current common method of setting pressure relief ports at the top of the inner liner, by arranging the two air outlet connection structures adjacent to each other and respectively docking with the heat dissipation fan assembly, the integration of the equipment is improved on the premise of ensuring cooking reliability.

[0123] In addition, for the first cooking chamber and the second cooking chamber during the intervention of steam, since some 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. 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 collecting box and further discharged to a structure / device such as a waste water box that can collect the condensed water, thereby ensuring the cleanliness of the equipment.

[0124] In this example, the bellows main body includes a vertically arranged partition board. The outer edge of the partition board extends 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 form the first heat dissipation chamber, and the second flanging, the partition board and the rear cover form the second heat dissipation chamber. The drainage structure is arranged in the second heat dissipation chamber corresponding to the heat dissipation air outlet. For example, a drainage structure is provided at the bottom of the second flanging. The drainage structure is a drain port with a connecting pipe section extending 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 height of the drainage structure can be lower than other positions. Exemplarily, the bottom wall of the heat dissipation bellows is set as a structure that gathers towards the drainage structure (such as a curved surface structure, an inclined surface structure, etc.).

[0125] 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.

[0126] Obviously, the combination of the above-mentioned 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 respectively form the first / second heat dissipation chambers with the front / rear cover bodies, they are connected to each other.

[0127] 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 specificity only from the perspective of the condensed water generated in the heat dissipation bellows. Exemplarily, the drainage structure is a plane / 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.

[0128] 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, a part flows back to the first / second cooking chambers, and a part is guided to the position of the drainage structure).

[0129] 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 the collection of condensed water, the first-stage condensed water recovery can be performed 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 performed 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 direction of the cooking chamber.

[0130] Obviously, the fact that the first / second drainage structures are substantially the same and their way of being aligned and communicated with the first / second air intake communication structures is only an exemplary description. Those skilled in the art can flexibly select the structural forms of the first / second drainage structures and the ways to realize reflux according to actual needs. For example, the structural forms and the ways to realize 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.

[0131] As in this example, the heat dissipation air box is arranged at the back of the cooking main body. The heat dissipation air box is generally in the shape of a volute. When observed in the width direction of the back of the cooking main body, the heat dissipation air box includes a first air box part and a second air box part. A first heat dissipation air inlet is arranged at the upper part of the first air box part, and a second heat dissipation air inlet is arranged at the back of the first air box part. A heat dissipation air outlet is arranged at the upper part of the second air box part. The first heat dissipation fan is arranged in the first air box part. The second air box part is generally located at a position close to the middle of the cooking main body. The first / air intake connection structure is respectively arranged at positions where the first cooking chamber and the second cooking chamber are close to each other. In this way, 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 air box, the structures of the first / second air box parts, the positions of the first / second heat dissipation air inlets, the heat dissipation air outlet, etc. to meet specific requirements. For example, widen the heat dissipation air outlet or extend another heat dissipation air outlet path, and arrange the second air intake connection structure at a position close to the middle of the second cooking chamber, etc.

[0132] In a possible implementation manner, the integrated built-in cooking device includes a second heat dissipation part 8 arranged on the cooking unit 200. For example, the cooking unit 200 mainly includes a stove shell 6, and two cooktops 7 are arranged on the stove shell 6. The second heat dissipation part 8 is arranged inside the stove shell. Obviously, those skilled in the art can determine the structural form, number of the cooktop installation positions, and the distribution manner of each cooktop installation position (in the case where there are multiple cooktops) on the stove top according to actual needs.

[0133] In a possible implementation manner, the stove shell 6 includes a bottom shell 601 and a stove top 602. For example, the stove top 602 is usually a glass layer or includes a glass layer. A stove shell air inlet 62 is arranged on the bottom shell 601, and an exhaust area 61 is arranged on the stove top 602. The exhaust area 61 serves as a shared exhaust structure for the cooking unit and the steam oven. The stove shell air inlet 62 is mainly used to suck in cold air through this and thus achieve heat dissipation for the internal space of the stove shell. The exhaust area can be an open structure, exhaust holes, exhaust mesh holes, etc. For example, the range hood configured on the side or above the cooktop can suck out the gas delivered to the exhaust area 61 in a timely manner.

[0134] In this example, there are two cooktop installation positions 6021 on the cooktop 602, and one cooktop 7 is provided on each of the two cooktop installation positions. On the side of the cooktop 602 close to the operator, there are knobs 6022 corresponding to the two cooktops 7. In addition, also on the side close to the operator, an operation panel 6023 serving as an interaction area is provided in the area between the two knobs. The interaction area is mainly used for performing interaction operations related to the device. For example, operations such as mode selection and parameter setting related to the cooktop unit can be performed on the operation panel, interaction operations related to the steam / oven function cooking unit integrated with the cooktop unit can also be performed, and operations related to exhaust, etc. integrated with the steam oven can also be performed. In addition, the operation panel can also be omitted, for example, the operation panel can be transferred to the panel of the range hood, etc.

[0135] In a possible implementation manner, the bottom shell 601 successively has a first installation area 6011, a second installation area 6012, and a communication area 6013 in the direction away from the operator. Among them, the first installation area is mainly used for installing the second electronic control board 162 described below, the second installation area 6012 is mainly used for installing a cross-flow fan serving as the second heat dissipation fan, and the communication area 6013 is an opening, mainly used to ensure the communication between the heat dissipation air outlet of the first heat dissipation fan and the exhaust area. As in this example, the cooktop housing air inlet 62 is located on the side (front side) of the cooktop housing close to the operator, and the second electronic control board is arranged at a position close to the cooktop housing air inlet and there is a certain distance between them.

[0136] As in this example, the exhaust area 61 is an open area, and an exhaust cover plate 611 with a porous communication structure such as a mesh structure is provided in the exhaust area. For example, the exhaust cover plate is roughly flush with the cooktop of the cooktop housing. When the cooktop is roughly flush with the kitchen countertop, the integrated installation of the device in the kitchen is realized. For example, a sealing structure such as a sealing ring can be provided between the exhaust cover plate and the cooktop corresponding to the exhaust area to prevent oil and liquid on the cooktop from entering the interior of the cooktop housing through the gap between the exhaust cover plate and the cooktop. And in this example, the cooktop housing air inlet 62 is provided on the side of the cooktop housing facing the operator (which can be called the front side), and the cooktop housing air inlet includes a plurality of communication holes distributed along the length direction of the cooktop housing. Obviously, those skilled in the art can flexibly adjust the structural form of the cooktop housing air inlet / exhaust area according to actual needs.

[0137] In this way, in this embodiment, three kinds of heat-carrying gases can be discharged through the exhaust area 61: one is the heat-carrying gas from the first heat dissipation air duct (mainly used to cool the door assembly of the steam oven and the heat-generating components at the top), one is the cooking medium from the first / second cooking chambers (mainly used for pressure relief and 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 cooktop unit).

[0138] In a possible implementation, 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 63 can be provided between the first exhaust port and the exhaust area. The exhaust connection structure 63 can be a corrugated pipe, a rigid pipe, a baffle, etc.

[0139] In a possible embodiment, a second electric control board 162 is arranged on the inner side of the bottom wall of the stove shell, and the second heat dissipation part 8 mainly cools the structure including the second electric control board by cooperating with the aforementioned stove shell air inlet. For example, the second heat dissipation part 8 mainly includes a second heat dissipation air duct 81 and a second heat dissipation fan 82. For example, the second heat dissipation fan 82 is a cross-flow fan, and the air inlet of the cross-flow fan is connected to the environment inside the stove shell. For example, the second electric control board 162 is arranged on the bottom wall of the stove shell and is located between the stove shell air inlet 62 and the air inlet of the cross-flow fan. In this way, when the cross-flow fan is running, the ambient air of the kitchen will be sucked into the environment inside the stove shell through the stove shell air inlet based on the generated negative pressure and cooled when it flows through the second electric control board. The air outlet of the cross-flow fan is connected to the air inlet side of the second heat dissipation air duct, and the 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 heating components such as electronic components inside the stove shell.

[0140] 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.

[0141] In a possible implementation, the air 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 discharge gas to the external environment. Therefore, as mentioned above, in the example, a common exhaust area 61 is provided on the stove unit.

[0142] On the one hand, those skilled in the art can determine the structural form of the exhaust area according to actual needs, such as an exhaust duct, an exhaust port, an exhaust hood, etc. On the other hand, it is obvious that the exhaust area does not have to be located close to the rear side of the stove 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 area.

[0143] In addition, the two sharing one exhaust area 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 duct; 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.

[0144] It can be seen that in the preferred embodiment of the present application, by arranging the heat dissipation fan assembly on the back of the cooking body and adopting a vertically arranged centrifugal fan, the space at the top of the inner pot is effectively released, which can not only further increase the volume of the inner pot in the height direction, but also reduce the size of the device in the height direction, such as reducing the height of the top of the front door frame of the cooking device. By setting the heat dissipation bellows as a double heat dissipation chamber / heat dissipation air inlet, the integrated embedded cooking device can be fully cooled by a double air inlet at one position. By arranging the installation space of the evaporation part, the heat dissipation fan assembly, the electric control board, etc. on the side (back side) of the cooking body close to the position of the first cooking cavity corresponding to the steaming function, the corresponding installation structure can be kept at a relatively low temperature. By integrating the structure for heat dissipation and exhaust pressure relief corresponding to the two cooking cavities into the heat dissipation bellows, 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 body can not only dissipate heat for the door assembly and the related structures on the top / side, but also provide a path for the pressure relief gas to ensure the cooking reliability of the device. By converging the exhaust position (heat dissipation outlet) of the first heat dissipation part with the exhaust position (second exhaust side) of the second heat dissipation part and connecting them with the exhaust area on the stove assembly, the heat dissipation gas from the steam-bake combination machine and the stove assembly and the cooking medium from the exhaust pressure relief of the steam-bake combination machine can be discharged in a centralized manner, thereby improving the integration of the device. At the same time, the exhaust area can change the exhaust side corresponding to the first heat dissipation air duct from the front exhaust to the top exhaust, thereby avoiding the phenomenon of heat being directly sprayed onto the user's body parts (such as approximately the user's legs), thereby improving the user experience.

[0145] So 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 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 principles 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 fall within the protection scope of the present application.
