Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, specifically to a cooking device. Background Technology

[0002] To meet user needs, cooking appliances capable of cooking food using one or more methods such as steaming, baking, and frying have emerged on the market. Taking hot air as the cooking medium as an example, the cooking principle is to continuously supply circulating hot air to the inner chamber containing the food, thus cooking the food through hot air baking. Taking steam as the cooking medium as an example, the cooking principle is to continuously supply high-temperature steam to the inner chamber containing the food, thus cooking the food through pure steaming. For example, cooking appliances with baking functions include ovens, steam ovens, and steam-baking-frying appliances. Compared to steaming, cooking appliances with baking functions have a higher temperature (cooking environment temperature) inside the cooking chamber during cooking, reaching up to 300℃. As a result, structures such as the top / back of the appliance (where electrical components with operating temperature requirements are installed) and the door assembly will also be at a high temperature.

[0003] To ensure the reliability of electrical components and other parts that require specific operating temperatures (and to extend their lifespan as much as possible), cooking equipment is equipped with heat dissipation components, including cooling fans and air ducts, in locations such as the top and back.

[0004] With the development of smart kitchen technology, structural forms have emerged that integrate image sensors, cameras, and other image acquisition components within the door assembly. However, the temperature of the door assembly can typically reach 130℃. Taking the camera as an example, to ensure its reliability and extend its lifespan, the camera should operate in an environment not exceeding 85℃. Therefore, effective cooling of the area where the camera is located is necessary. This can be achieved by using heat dissipation components to cool both the door assembly and other temperature-sensitive electrical components, or by installing a fan that directly blows heat onto the camera. However, the former method provides relatively little cooling, while the latter's installation location can affect the camera's field of view and may result in uneven heat dissipation. Therefore, there is still room for improvement in effectively cooling image acquisition components integrated into the door assembly. Utility Model Content

[0005] This application aims to solve at least part of the above-mentioned technical problems and / or at least part of the above-mentioned technical problems. Specifically, it aims to solve how to effectively cool down image acquisition components configured in door components to ensure the operational reliability of image acquisition components and extend their service life as much as possible, thereby ensuring the cooking performance of cooking equipment containing image acquisition components.

[0006] In view of this, this application provides a cooking device, comprising: a cooking body having a cooking chamber; a door assembly disposed in the cooking body in an openable manner, the door assembly having a first channel and a second channel adjacent to the cooking chamber; and an image acquisition assembly disposed in the first channel; the cooking device further comprising: a heat dissipation assembly including one or more heat dissipation fans, the heat dissipation fans being able to introduce air from the bottom of the first channel into the first channel, thereby dissipating heat from the image acquisition assembly.

[0007] This configuration allows for heat dissipation of the image acquisition components.

[0008] The statement that "the cooling fan can at least introduce air from the bottom of the first channel into the first channel" includes the following two scenarios:

[0009] Scenario 1: The cooling fan introduces air from the bottom of the first channel and other directions such as the side into the first channel;

[0010] Scenario 2: The cooling fan introduces air from the first channel and the second channel into the first channel.

[0011] Based on this, the first channel can be introduced by a straight line or by constructing a specific path such as a curve or a broken line before introducing it.

[0012] In one possible implementation of the above-mentioned cooking equipment, the cooling fan is located at the bottom of the door assembly near the first channel, and the image acquisition assembly is located at the top of the first channel.

[0013] This configuration provides a possible relative positional relationship between the cooling fan and the image acquisition components.

[0014] In one possible implementation of the cooking equipment described above, the cooling fan is positioned near the middle or near the end of the first channel along the width direction of the door assembly.

[0015] This configuration provides a possible layout for the cooling fan.

[0016] In one possible implementation of the above-mentioned cooking equipment, when viewed along the width direction of the door assembly, the cooling fan is provided near one of its ends; or the cooling fan is provided near both ends of the door assembly; or the cooling fan is provided near the middle of the door assembly.

[0017] This configuration provides a possible arrangement of the cooling fan, allowing those skilled in the art to select a suitable layout based on actual cooling requirements.

[0018] In one possible implementation of the above-mentioned cooking equipment, the heat dissipation component includes: a heat dissipation fan bracket disposed on the door assembly, and the heat dissipation fan disposed on the heat dissipation fan bracket; wherein, the heat dissipation fan bracket forms an air inlet channel, and air corresponding to the bottom position of the first channel and / or the second channel can enter the air inlet channel through the air inlet side of the air inlet channel, and the air outlet side of the air inlet channel can communicate with the first channel.

[0019] With this configuration, it is possible to introduce air for heat dissipation from the bottom of the door assembly into the first channel via a heat dissipation fan bracket.

[0020] It is understood that those skilled in the art can determine the structural form of the air inlet / outlet side, the connection position between the air outlet side and the cooling fan, etc., according to actual needs. For example, the air outlet side and the cooling fan can be connected in multiple positions such as the bottom and the side.

[0021] In one possible implementation of the above-mentioned cooking equipment, the heat dissipation fan bracket includes a first part and a second part, and the air inlet channel includes a first sub-air inlet channel formed in the first part and a second sub-air inlet channel formed in the second part. Air enters the first channel sequentially through the first sub-air inlet channel and the second sub-air inlet channel; wherein at least a portion of the second sub-air inlet channel is accommodated in the second channel.

[0022] With this configuration, it is possible to achieve heat dissipation for the image acquisition components through the constructed air intake path of the first channel and / or the second channel → second channel → first channel.

[0023] In one possible implementation of the above-mentioned cooking equipment, the air intake side of the air intake channel includes at least a first air inlet, which is located at the position of the heat dissipation fan bracket corresponding to the first channel.

[0024] In one possible implementation of the above-mentioned cooking equipment, the air intake side of the air intake channel includes a second air inlet, which is disposed at the position of the heat dissipation fan bracket corresponding to the second channel.

[0025] In one possible implementation of the cooking equipment described above, the second air inlet is located on the heat dissipation fan bracket at a position corresponding to the second channel and close to the first channel.

[0026] This configuration allows for a reduction in the temperature of the air used for heat dissipation.

[0027] In one possible implementation of the above-mentioned cooking equipment, the first sub-air inlet channel and the second sub-air inlet channel form a certain angle.

[0028] This configuration provides a possible way to construct the air intake path.

[0029] In one possible implementation of the above-mentioned cooking equipment, the first sub-air inlet channel and the second sub-air inlet channel are perpendicular to each other.

[0030] This configuration provides a possible structural form for the air intake channel, and the verticality here should be understood as approximately vertical.

[0031] In one possible implementation of the above-mentioned cooking equipment, the second sub-air inlet channel is connected to the heat dissipation fan along the thickness direction of the door assembly.

[0032] This configuration allows for air intake of the cooling fan through bottom air intake and side air exhaust.

[0033] The phrase "the second sub-air inlet channel is connected to the heat dissipation fan along the thickness direction of the door assembly" includes the following scenarios:

[0034] Scenario 1: The second sub-air intake channel is completely contained within the first channel. The air inlet of the cooling fan is connected to the second sub-air intake channel at the side (outer side) of the first channel. Alternatively, the air inlet of the cooling fan has (its own structure extending into) / added (a new structure) a connecting pipe section that can connect to the second sub-air intake channel within the first channel.

[0035] Scenario 2: The second sub-inlet channel is located just outside the first channel and connects to the cooling fan.

[0036] Scenario 3: The second sub-air inlet channel is partially housed within the first channel and extends into the first channel. The second sub-air inlet channel is connected to the air inlet of the cooling fan at a position in the first channel near the second channel.

[0037] In one possible implementation of the above-mentioned cooking equipment, the image acquisition component includes an image acquisition part, wherein, viewed along the width direction of the door assembly, the image acquisition part is disposed near the middle of the door assembly.

[0038] This configuration provides a general layout for the image acquisition components. In this way, image acquisition components such as cameras can better acquire image data from the field of view, and cooling fans in different locations can adequately cool the image acquisition components.

Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application. For example, although this embodiment describes a cooking device in conjunction with a single-function oven, this is not intended to limit the scope of protection of this application. Without departing from the principles of this application, those skilled in the art can apply this application to other application scenarios. For example, the oven can be replaced with a steam oven, a dual-cavity oven, or other cooking devices that also include hot airflow as a cooking medium. Furthermore, although the temperature of a cooking environment corresponding to steam is relatively lower than that of hot airflow, this application can also be applied to cooking devices corresponding to steam, such as steam ovens.

These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0077] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0078] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, the detailed structure and principles of ovens well-known to those skilled in the art are not described in detail, in order to highlight the main points of this application.

[0079] Example 1

[0080] Main reference Figures 1 to 8 In one possible implementation, the cooking device 100 is an oven, which can cook food by hot air baking. The oven mainly includes a cooking body 1, which includes a housing 11 and an inner liner 12 disposed within the housing 11. The inner liner 12 forms a cooking chamber. By operating a corresponding cooking mode, food placed in the cooking chamber can be cooked by hot air baking. The inner liner 12 may be equipped with a shelf 13, allowing food to be placed directly on the shelf 13 or on a container (such as a plate) placed on the shelf 13. One or more mounting positions for the shelf 13 can be configured within the cooking chamber. For example, a stand 14 is provided within the inner liner 12, and the shelf 13 can be positioned at different heights on the stand 14. Since the baking function is closely related to the temperature of the hot airflow as the cooking medium, heating elements such as heating tubes can be installed at the top, sides, and bottom of the inner cavity 12 to provide primary or auxiliary / supplementary heating of the hot airflow in the cooking cavity when needed.

[0081] In one possible implementation, the cooking body 1 has an openable door assembly 2 on the side facing the operator (e.g., the front side), and an image acquisition assembly 3 is mounted on the door assembly 2. By opening the door assembly 2, the user can place and remove ingredients / food within the cooking chamber. For example, the door assembly 2 can move relative to the cooking body 1 by flipping up / down, pivoting left / right, or pushing / pulling. Before cooking, during cooking, and after cooking, the cooking performance of the cooking equipment 100 can be ensured based on image data acquired by the image acquisition assembly 3 related to the type, position, quantity, and cooking progress of the ingredients. The parameters of the cooking equipment 100 can be adjusted based on the image data, or the image data can be used to link with other devices associated with the current cooking process, such as range hoods and stoves.

[0082] In one possible implementation, the door assembly 2 includes an outer glass layer 21, an inner glass layer 22, and a middle glass layer 23 located between them. The outer glass layer 21 and the middle glass layer 23 form a first channel 201, and the middle glass layer 23 and the inner glass layer 22 form a second channel 202. The image acquisition assembly 3 is disposed in one of these channels. As in this example, the image acquisition assembly 3 is disposed in the first channel 201.

[0083] In one possible implementation, the image acquisition component 3 includes an image acquisition element 31. As in this example, the image acquisition element 31 includes a camera, which is generally positioned near the center of the first channel 201 along its width and approximately above it along its height. The camera can capture image data of an area typically containing at least the food ingredients from a downward-sloping perspective. While the camera's viewing angle is relatively fixed in this example, it can obviously be configured to have an adjustable viewing angle, such as by sliding along the width / height direction, rotating around its own axis, or flipping in the up / down / left / right directions, to better acquire cooking-related image data.

[0084] In one possible implementation, the image acquisition component 3 includes at least one supplementary lighting component 32, such as a supplementary light lamp. In this example, there are two supplementary lights lamps, which are placed on both sides of the image acquisition component 31 along the width direction, so as to provide supplementary lighting to the image acquisition field of view according to actual needs, thereby ensuring the quality of the image data acquired by the image acquisition component 31.

[0085] In one possible implementation, the image acquisition component 3 includes an image acquisition mounting bracket 33, which is disposed on the door assembly 2. The image acquisition component 31 and the supplementary lighting component 32 are both disposed on the image acquisition mounting bracket 33. For example, the wiring harness 34 related to the camera and the supplementary lighting can pass through the bottom of the door assembly into the cooking body and then connect to the control panel inside the cabinet.

[0086] In one possible implementation, the oven includes a heat dissipation assembly 4, which includes a heat dissipation fan 41. The heat dissipation fan 41 is disposed on a heat dissipation fan bracket 42 and is located within a first channel 201 on which the image acquisition component 3 is installed. The heat dissipation fan bracket 42 forms an air inlet channel 43. In this way, under the guidance of the heat dissipation fan 41, external air corresponding to the position of the first channel 201 and / or the second channel 202 can enter the air inlet channel 43 through the air inlet side. The air outlet side of the air inlet channel 43 can communicate with the first channel 201, so that under the guidance of the heat dissipation fan 41, external air can enter the first channel 201 through the air inlet channel 43 to dissipate heat from the image acquisition component 3. Taking "first channel 201 and second channel 202" as an example, it may include, but is not limited to: the air inlet side of the air inlet channel 43 can simultaneously cover the positions corresponding to the first channel 201 and the second channel 202; the air inlet side of the air inlet channel 43 includes two air inlets, which respectively cover the positions corresponding to the first channel 201 and the second channel 202.

[0087] In one possible implementation, the cooling fan bracket 42 includes a first portion 421 and a second portion 422, with the air inlet side disposed in the first portion 421 and the air outlet side disposed in the second portion 422, the second portion 422 being located above the first portion 421. The air inlet channel 43 includes a first sub-air inlet channel 431 formed in the first portion 421 and a second sub-air inlet channel 432 formed in the second portion 422, the first sub-air inlet channel 431 and the second sub-air inlet channel 432 communicating with each other, wherein the first sub-air inlet channel 431 and the second sub-air inlet channel 432 form a certain angle between them. Thus, guided by the cooling fan 41, external air sequentially enters the second channel 202 through the first sub-air inlet channel 431 and the second sub-air inlet channel 432. The first portion 421 overlaps with both the first channel 201 and the second channel 202 in the thickness direction (projection on the horizontal plane) of the door assembly 2, and at least a portion of the second portion 422 is accommodated within the second channel 202. In this way, the air intake path of the cooling fan 41 is roughly as follows: external air is drawn into the first sub-intake channel 431, flows into the second sub-intake channel 432, and is drawn into the first channel 201 at approximately the position of the second channel 202.

[0088] It should be noted that the phrase "at least a portion of the second part 422 is contained within the second channel 202" should be understood as meaning that at least a portion of the air flows through the second channel 202 before being introduced into the first channel 201. This could be all, a portion, or most of the air. For example, most of the structure of the second part 422 is contained within the second channel 202, while a small portion is located in the first channel 201 near the second channel 202. In this way, most of the air enters the first channel 201 by flowing through the second channel 202 first and then through the first channel 201. For the small portion of air, although it is drawn into the first channel 201 at a location corresponding to the first channel 201, its flow is redirected during its journey to the first channel 201 due to the structural arrangement of the first part 421 and the second part 422.

[0089] It should be noted that the phrase "the first sub-inlet channel 431 and the second sub-inlet channel 432 form a certain angle" is understood to mean that the airflow direction changes as it flows sequentially through the first sub-inlet channel 431 and the second sub-inlet channel 432. Based on this, those skilled in the art can determine the structural form of the first / second sub-inlet channels, their relative positions, and the size of the angle according to actual needs. This can include, but is not limited to, one being a straight channel and the other a curved / zigzag channel, both being straight channels (e.g., angles of 30°, 45°, 60°, 90°, 120°, etc.), and both being curved / zigzag channels.

[0090] It is understood that those skilled in the art can determine the structural form of the cooling fan bracket, the number of its components, and the structural form of the first / second part, the number of components in each part, and the way in which they constitute the cooling fan bracket, according to actual needs. For example, the first and second parts can be fixedly connected or integrally formed, and each part can be constructed from one or more components. For instance, in the first part, the bottom portion of the first / second air inlet and the side portion forming the first air inlet sub-channel are two separate structures.

[0091] In one possible implementation, the first sub-air inlet channel 431 and the second sub-air inlet channel 432 are approximately perpendicular. In this example, the first sub-air inlet channel 431 is approximately horizontal, and the second sub-air inlet channel 432 is approximately vertical, forming an approximately L-shaped structure. Obviously, this is only an exemplary description, and those skilled in the art can flexibly adjust its structural form, relative positions, etc., according to actual needs; for example, it could also be a T-shaped structure, a C-shaped structure, etc. Taking the C-shaped structure as an example, under the guidance of the cooling fan 41, air can enter the second channel 202 along the middle and / or upper part of the C-shaped structure. Exemplarily, the middle part of the C-shaped structure is accommodated within the second channel 202, and a portion of the upper part of the C-shaped structure extends into the second channel 202.

[0092] In one possible implementation, the air intake side of the air intake channel 43 includes a first air intake 441 and a second air intake 442. The first air intake 441 is located in the air intake channel 43 at a position corresponding to the first channel 201, and the second air intake 442 is located in the air intake channel 43 at a position corresponding to the second channel 202. Furthermore, the second air intake 442 is located in the second channel 202 near the first channel 201. In this example, the first air intake 441 includes a plurality of strip-shaped holes extending along the thickness direction of the door assembly 2 (the plurality of strip-shaped holes are arranged along the width direction of the door assembly 2), and the second air intake 442 includes a plurality of strip-shaped holes extending along the width direction of the door assembly 2 (the plurality of strip-shaped holes are arranged along the width direction of the door assembly 2). Obviously, those skilled in the art can determine the structural form, number, location, and air volume of the first air inlet 441 and the second air inlet 442 according to actual needs. For example, it can be an open area, a grille structure, etc. When there are multiple first / second air inlets 442, their structural form (which can be the same or different) and distribution (such as uniform / non-uniform, symmetrical, etc.) can be flexibly set according to actual needs. In this way, since the first air inlet 441 and the second air inlet 442 are both located relatively far from the inner liner 12, the front door frame, etc., the air temperature at these locations is relatively low. Therefore, this arrangement can improve the heat dissipation effect on the image acquisition module to a certain extent.

[0093] It is understood that those skilled in the art can determine the number, location, and structural form of the air inlets on the air intake side according to actual needs. For example, it may only include the first air inlet 441, which may be located near the outer side of the first channel 201. In this case, compared to the location corresponding to the second channel 202, the location corresponding to the first channel 201 is farther away from the inner liner 12, the front door frame, etc., and therefore the air temperature is relatively lower.

[0094] The air intake direction of the first / second air inlet 442 can be vertical or inclined upward from the direction away from the inner liner 12 toward the direction closer to the inner liner 12, so as to further increase the temperature of the air used for heat dissipation. This can be achieved by means of oblique holes or adding baffles at the air inlet.

[0095] In one possible implementation, the cooling fan 41 is positioned near the end of the first channel 201 along the width direction of the door assembly 2. Furthermore, since the aforementioned air intake channel 43 requires air to enter from the bottom of the door assembly 2, the cooling fan 41 is positioned near the bottom of the first channel 201. In this way, guided by the cooling fan 41, air located below the door assembly 2 near the outer region (corresponding to the position of the first channel 201) flows into the position corresponding to the second channel 202 along the first sub-air intake channel 431, and is then drawn into the first channel 201 via the second sub-air intake channel 432 on the inner side of the first channel 201 (corresponding to the position of the second channel 202). Based on this, under the action of the cooling fan 41, a large-scale turbulence is formed throughout the second channel 202, thereby sufficiently cooling the image acquisition component 31. Furthermore, the supplementary lighting can also be cooled simultaneously.

[0096] Furthermore, since the aforementioned air intake channel 43 requires air to enter from the bottom of the door assembly 2, the cooling fan 41 is positioned near the bottom within the first channel 201. Thus, guided by the cooling fan 41, air located below the door assembly 2 in the outer region (corresponding to the position of the first channel 201 and a partial position of the second channel 202 near the first channel 201) flows into the cooling fan bracket 42 along the first sub-air intake channel 431, and is then drawn into the first channel 201 via the second sub-air intake channel 432 on the inner side of the first channel 201 (roughly corresponding to the position of the second channel 202). Based on this, under the action of the cooling fan 41, a large-scale turbulence is formed throughout the entire second channel 202, thereby sufficiently cooling the image acquisition component 31 and simultaneously cooling the supplementary lighting component 32.

[0097] In one possible implementation, the door assembly 2 has a door exhaust region 24 above it. After cooling the outer / middle glass 23, image acquisition component 3, etc., the turbulent flow is discharged outside the door assembly 2 through the portion of the door exhaust region 24 corresponding to the first channel 201. Exemplarily, the door assembly 2 has a door exhaust element near the top, and the door exhaust region 24 is disposed on the door exhaust element. The door exhaust element can be fixedly connected to one or more of the outer / middle / inner glass 22; for example, the door exhaust element is adhesively disposed on the inside of the outer glass 21.

[0098] In one possible implementation, the oven includes a fan shroud assembly 5 capable of distributing hot airflow into the cooking chamber. The fan shroud assembly 5 primarily includes a fan shroud 51, a temperature-regulating fan 52 (typically a centrifugal fan), and a second heating element 53 such as a heating coil. The temperature-regulating fan 52 is primarily used to maintain the temperature of the hot airflow within the cooking chamber as uniformly as possible. Exemplarily, the fan shroud 51 forms a hot air chamber, and the temperature-regulating fan 52 is disposed within the hot air chamber. The second heating element 53 may be disposed within or near the hot air chamber. Taking a heating coil as an example, the heating coil may be disposed within the hot air chamber, and the temperature-regulating fan 52 may be disposed within the area enclosed by the heating coil. The fan shroud 51 has a return air vent 541 near the centrifugal fan, and the fan shroud 51 also has an air inlet 542, which may be disposed approximately circumferentially around or partially around the return air vent 541. In this way, under the action of the temperature-regulating fan 52, the air inside the inner liner 12 is drawn into the hot air chamber through the return air vent 541, heated by the heating coil, and transformed into hot airflow carrying heat. The hot airflow is then thrown towards the outer air outlet 542 and thus sent back into the inner liner 12. This cycle continuously distributes hot airflow to the surface of the food to be cooked, thereby cooking the food using a hot air roasting method according to the corresponding control program.

[0099] It should be noted that the hot air chamber mentioned here is not necessarily a complete chamber, but rather should be understood as the mounting location for accommodating the temperature equalizer 52 and the heating coil. Therefore, those skilled in the art can determine the structural form and communication configuration of the hot air chamber according to actual needs. For example, the temperature equalizer 52 and the heating coil can be placed in the same chamber or in two separate connected chambers. The hot air chamber can achieve communication with the cooking chamber through multiple connecting holes, or by making a certain part of it an open structure.

[0100] In one possible implementation, the oven further includes a whole-machine heat dissipation assembly 6, which mainly includes a heat dissipation duct 62 and a whole-machine heat dissipation fan 61. The whole-machine heat dissipation fan 61 is mainly used to draw air from the external environment into the heat dissipation duct 62 and then discharge it. During the airflow through the heat dissipation duct 62, it can dissipate heat from components such as the power board and electrical components to ensure the reliable operation of the oven. The whole-machine heat dissipation fan 61 can be located at the top, side, or other positions of the inner cavity 12. For example, the whole-machine heat dissipation fan 61 is located at the top of the inner cavity 12 and between the top outer side of the oven body 11 and the inner cavity 12.

[0101] In one possible implementation, the overall cooling fan 61 is a centrifugal fan or a cross-flow fan, and at least a portion of the air inlet side of the cooling duct 62 faces the door assembly 2, so that the cooling fan 41 can dissipate heat to the top area while also dissipating heat to the door assembly 2 to a certain extent. For example, the overall cooling fan 61 is a cross-flow fan disposed on the top of the inner liner 12.

[0102] In one possible implementation, the air inlet side of the heat dissipation duct 62 is aligned to at least a certain extent with the air outlet communication area 24 on the heat dissipation outlet component 26, so that the hot airflow above the first channel 201 and / or the second channel 202 can be drawn into the heat dissipation duct 62 to ensure the heat dissipation performance of the whole machine.

[0103] In one possible implementation, the door assembly 2 has an air outlet communication area 24 near its upper part to allow the timely discharge of heat-carrying gas from the first and second channels. For example, in this example, a heat dissipation air outlet 26 is provided on the door assembly, and the heat dissipation air outlet 26 has the air outlet communication area 24. Exemplarily, the air outlet communication area includes multiple air outlet communication holes. Below the door assembly 2, in addition to the aforementioned first / second air inlets 442, there is also an air inlet communication area 25 located below the first / second channels 202, which communicates with the area near the bottom of the oven (such as the area between the bottom of the inner liner 12 and the cabinet 11). This air inlet communication area may include multiple air inlet communication holes. This allows the overall cooling fan 61 located at the top of the inner liner 12 to dissipate heat to the bottom area of ​​the oven, further reducing the temperature of the air introduced into the first channel 201 via the air inlet channel 43. In this example, the air intake connection area is an air intake grille that is connected to both the first channel 201 and the second channel 202. Obviously, those skilled in the art can flexibly adjust it according to actual needs. For example, the structure can also be an open area / strip hole, the air intake direction can be adjusted to be inclined, and the air intake connection area can be fully distributed in the first / second channel 202 or only distributed in a local area (such as the air intake connection area corresponding to the second channel 202 is set on both sides along its width direction, or on the outside along its thickness direction, etc.).

[0104] Main reference Figure 9 In this embodiment, with a cooling fan 41 installed at the lower left corner of the first channel 201 between the outer glass layer 21 and the middle glass layer 23, the camera temperature is 101.4℃ and the supplementary light temperature is 65.1℃. Note: Because simulation experiments are typically conducted under harsh conditions, the simulation results are only used to compare the differences between different design schemes and may differ from actual operating results. For example, in actual operation, the camera temperature may reach its required safe temperature range.

[0105] Example 2

[0106] Main reference Figure 10 In this embodiment, two cooling fans 41 are included, and the two cooling fans 41 are respectively disposed in the first channel 201 near the two ends along the width direction of the door assembly 2. Exemplarily, the two cooling fans 41 are arranged approximately symmetrically. The cooling assembly 4 and other structures of the oven are generally the same as in the embodiment, and will not be described again here.

[0107] In this way, the image acquisition component 3 is cooled by introducing air from two locations into the second channel 202. The structure and air intake mechanism of the cooling fan brackets 42 corresponding to the two cooling fans 41 can be the same or different. For example, the structure, number, and coverage of the air inlets on the air intake side can be the same or different. For example, the two cooling fans 41 and their brackets are arranged approximately symmetrically. In this case, the turbulent airflow corresponding to the two cooling fans 41 can cool the image acquisition module by flowing from both sides to the image acquisition module. Furthermore, after the airflow from both parts convects, it generates more directional turbulence, thus cooling the image acquisition module by flowing from the bottom to the image acquisition module. This solution can be adopted if cost and installation space permit. For cases where the width of the door component 2 is large, this solution can ensure the heat dissipation effect of the image acquisition component 3.

[0108] In this embodiment, with a cooling fan 41 installed at the lower left and lower right corners of the first channel 201 between the outer glass 21 and the middle glass 23, the temperature of the camera is 92.8°C and the temperature of the fill light is 52.1°C.

[0109] Example 3

[0110] Main reference Figure 11 In this embodiment, a single cooling fan 41 is provided, which is positioned approximately in the middle of the door assembly 2 along its width. The cooling assembly 4 and other structures of the oven are largely the same as in the previous embodiment and will not be described again here.

[0111] In this way, air is introduced from the middle position into the second channel 202 to cool the image acquisition module by flowing from the bottom to the image acquisition module. As the airflow collides with the bottom of the image acquisition component 3, it disperses into two turbulent streams that cool the supplementary lights on both sides. However, the air temperature is higher near the middle air intake compared to the sides, which may affect the heat dissipation effect to some extent. The air intake direction can be set to be obliquely upwards from the direction away from the inner liner 12 towards the direction closer to the inner liner 12 and / or obliquely upwards from the sides towards the middle, to introduce relatively cooler air into the air intake channel 43 and dissipate heat from the image acquisition component 3.

[0112] In this embodiment, with a cooling fan 41 positioned in the lower middle of the first channel 201 between the outer glass layer 21 and the middle glass layer 23, the camera temperature is 86.4℃ and the fill light temperature is 56.2℃. However, this simulation experiment did not consider that the air temperature in the middle region is higher than that at both ends, so the heat dissipation effect will be more ideal than in reality. As a comparative example, if the camera and fill light are moved from the first channel to the second channel, the camera temperature is 110.9℃ and the fill light temperature is 74.3℃.

[0113] As can be seen, in the preferred embodiment of this application, the cooking performance of the cooking equipment can be guaranteed based on the image data collected within the cooking cavity by setting up the image acquisition component. Specifically, the operating parameters of the oven itself or other related equipment such as the range hood can be adjusted based on the acquired image data. With the image acquisition component in place, the heat dissipation component effectively dissipates heat, thus ensuring the reliability of the image acquisition component. Through the cooperation of the heat dissipation component and the overall heat dissipation component, the heat dissipation performance of the cooking equipment is guaranteed.

[0114] The technical solutions of this application have been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
