Description

Technical Field

[0001] This utility model relates to the field of small kitchen appliances, and in particular to a deodorizing oven. Background Technology

[0002] To improve the space utilization of ovens, existing technologies such as utility model patent CN213309179U and invention patent CN102357016A have changed the traditional square oven structure to a round one. Although this increases the actual usable volume and occupies less space, the baking trays mentioned above are used for direct baking. The baking trays do not treat the oil fumes generated during baking, causing the oil fumes to float in the air. Especially when baking food indoors, the odors in the oil fumes will pollute and be absorbed into the room, leaving a lingering odor. On the other hand, some existing oil fume removal structures of baking trays can only rely on circulating air to disperse the oil fumes, which is a false smoke removal. The oil fumes still cannot be removed, affecting the taste and appetite of the baked food. Utility Model Content

[0003] The purpose of this invention is to provide a deodorizing oven that solves the problem that existing ovens cannot effectively remove oil fumes and odors, thus achieving effective treatment of oil fumes and odors.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a deodorizing oven, comprising a spherical or nearly spherical shell, wherein a cooking cavity is provided inside the shell, and a heating element, a baking tray, a fan assembly, and a deodorizing component are provided inside the cooking cavity. The heating element is located in the upper half of the cooking cavity, the baking tray is placed below the heating element, and the deodorizing component is located in the airflow path of the fan assembly. The fan assembly operates so that the fumes in the cooking cavity pass through the deodorizing component.

[0005] After adopting the above technical solution, the present invention has the following advantages: When the size of the baking pan is fixed, the upper and lower parts of the rectangular oven shell have the same or similar volume. In the present invention, the upper and lower parts of the spherical or near-spherical shell have a smaller volume than the middle part. When placing a baking pan of the same size, the overall volume of the oven is smaller and easier to store. Secondly, by setting a deodorizing component in the airflow path of the fan assembly, the working of the fan assembly allows the oil fumes in the cooking cavity to pass through the deodorizing component, changing the existing situation of directly baking with the baking pan without treating the oil fumes or the false smoke removal. It not only blows away the oil fumes, but also more effectively removes the oil fumes and odors produced by baking food, minimizing the odors floating in the oil fumes, thereby solving the problem of residual odors in the room due to baking food as much as possible, and also reducing the impact of odors on the taste of baked food, improving the taste and appetite of baked food.

[0006] Furthermore, the cooking cavity is provided with an airflow channel, and the fan assembly and deodorizing component are arranged in the airflow channel. The upper port of the airflow channel is connected to the space above the baking pan in the cooking cavity, and the lower port of the airflow channel is connected to the space below the baking pan in the cooking cavity, so that the oil fumes in the cooking cavity, driven by the fan assembly, pass through the deodorizing component and then flow back to the bottom of the baking pan along the airflow channel to form a hot air circulation.

[0007] By adopting the aforementioned technical solution, an airflow channel is set up in the cooking cavity, and the fan assembly and deodorizing component are placed in the airflow channel. This enables the hot air circulation of the cooking cavity, after being purified by the deodorizing component, to flow back to the bottom of the baking pan through the airflow channel. This not only achieves efficient reuse and uniform distribution of heat, but also reduces heat loss and improves cooking efficiency and food quality. Under the same baking effect, the working time and power of the heating element can be reduced, and the treatment effect of oil fumes and odors is greatly enhanced, providing a cleaner and odorless cooking environment.

[0008] Furthermore, the housing is provided with an exhaust port, the cooking cavity is provided with an airflow channel, the fan assembly and the deodorizing component are arranged in the airflow channel, the upper port of the airflow channel is connected to the space above the baking pan in the cooking cavity, and the lower port of the airflow channel is connected to the exhaust port, so that the oil fumes in the cooking cavity are driven by the fan assembly and then discharged from the exhaust port after passing through the deodorizing component.

[0009] By adopting the aforementioned technical solution, the shell is equipped with an exhaust port. Combined with the airflow channel, fan assembly, and deodorizing component in the cooking cavity, the oil fumes are first purified by the deodorizing component under the drive of the fan assembly, and then the deodorized hot oil fumes are discharged from the oven through the exhaust port. This avoids excessive accumulation of hot air in the cooking cavity as much as possible, helps to maintain the stability of the oven temperature, makes the baking process more stable and controllable, and prevents the food quality from being adversely affected by excessively high temperatures, such as avoiding food from burning or drying out.

[0010] Furthermore, the airflow channel includes airflow pipes respectively disposed on both sides of the heating element. The housing is provided with a knob, and the airflow pipes are fixed on the knob. The knob rotates relative to the housing to make the airflow pipes rotate, thereby changing the position of the upper port of the airflow channel relative to the baking pan.

[0011] By employing the aforementioned technical solution, airflow pipes are installed on both sides of the heating element, which can more broadly cover different areas within the cooking cavity. This ensures that the generated fumes are extracted and deodorized from more angles, further improving the deodorization effect and minimizing the problem of fumes lingering or insufficient purification in certain areas. By rotating the knob to change the position of the upper end of the airflow pipe relative to the baking tray, it is possible to more precisely extract fumes from different locations around the baking tray that produce odors. Since different parts of the food produce varying degrees of fumes and odors during the baking process, adjusting the position of the upper end of the airflow pipe by rotating the knob allows for targeted extraction of odor-concentrated areas, which helps improve deodorization efficiency and allows odors in the oven to be removed more quickly and thoroughly.

[0012] Furthermore, the cooking cavity is provided with an airflow hood that fits against the inner wall of the cooking cavity, and an airflow channel is formed between the airflow hood and the inner wall of the cooking cavity.

[0013] By adopting the aforementioned technical solution, the airflow shroud can guide the oil fumes drawn by the fan assembly to flow along the inner wall of the cooking cavity, so that the oil fumes form a more regular and stable flow path in the cooking cavity, avoiding turbulence and eddies in the oil fumes, making the oil fume flow smoother, reducing energy loss, and enabling the fan assembly to maintain the required oil fume flow rate and volume with lower power. The low-resistance airflow channel also helps to reduce noise generation, creating a quiet cooking environment for users.

[0014] Furthermore, the deodorizing component includes a heating plate and a catalyst, with the heating plate located upstream of the catalyst.

[0015] Using the aforementioned technical solution, the heating plate is located upstream of the catalyst. The heating plate can preheat the oil fumes entering the deodorizing component. After passing through the heating plate, the temperature of the oil fumes rises, and the molecular motion intensifies. This allows the oil fumes to react more fully with the active sites on the catalyst surface when they subsequently come into contact with the catalyst, improving catalytic efficiency and thus more effectively decomposing oil fumes and volatile organic compounds. Furthermore, the catalyst can only exert its optimal activity within a certain temperature range. After the heating plate preheats the oil fumes, it can place the catalyst in a more suitable working temperature environment, thereby stimulating the activity of the catalyst and enabling it to more efficiently catalyze the decomposition of odor substances, greatly improving the deodorizing ability of the entire deodorizing component.

[0016] Furthermore, the deodorizing component is positioned close to the heating element.

[0017] Using the aforementioned technical solution, the heating element emits a large amount of heat when working. The deodorizing component can directly utilize the heat emitted by the heating element, which helps to activate certain types of deodorizing materials (such as catalysts), improve their activity and purification effect, and enhance the ability to remove oil fumes and odors. Even after the heating element is turned off, there will still be some residual heat. The deodorizing component can make full use of this residual heat, so that the deodorizing reaction can continue at a relatively high temperature, accelerate the reaction rate, and further improve the deodorizing efficiency.

[0018] Furthermore, the cooking cavity is provided with a slide rail arranged around the circumference of the baking pan and a drive slider disposed on the slide rail. The heating element is fixed on the drive slider to drive the heating element to move along the slide rail; and / or, an annular track is provided around one of the circumferences of the upper housing and the lower housing, and a roller is provided around the other of the circumferences of the upper housing and the lower housing. The roller is driven by a power motor to drive the upper housing to rotate relative to the lower housing.

[0019] Using the aforementioned technical solution, by driving the slider to move along the slide rail, the heating element can heat different positions within the cooking cavity. For example, when baking foods of different shapes and sizes, the heating element can be moved to a better position to ensure that all parts of the food are heated evenly, improving the cooking effect and minimizing the possibility of localized burning or undercooking. When not in use, the heating element can be moved to a corner or other location for easy food handling and oven cleaning; and / or, when the upper shell rotates relative to the lower shell, the food within the cooking cavity receives heat from the heating element from all directions, thus minimizing the uneven heating problems that may occur in traditional ovens due to fixed-position heating. The rotation of the upper shell relative to the lower shell also promotes airflow circulation within the cooking cavity, creating a more uniform temperature field.

[0020] Furthermore, the middle part of the baking pan is raised upward relative to the periphery of the baking pan, the periphery of the baking pan is provided with a downwardly recessed oil leakage area, and the outer ring of the baking pan located in the oil leakage area is raised upward.

[0021] Using the aforementioned technical solution, the baking pan is convex in the center, allowing excess oil to flow naturally to the surrounding oil-draining area due to gravity during cooking. This reduces the contact between food and oil, decreasing the greasiness of the food. Because the convex part is closer to the heat source, heat is transferred to all parts of the baking pan more quickly, reducing the temperature difference between the center and edges and ensuring more even heating of the food during baking. The oil-draining area design facilitates the collection of oil and food residue generated during cooking, concentrating these substances within the area and minimizing spillage, making cleaning the baking pan easier. Finally, the outer ring of the baking pan within the oil-draining area curves upwards, effectively preventing oil from overflowing onto the outside of the pan, avoiding soiling the oven surface and maintaining a clean cooking environment. Even when moving the baking pan, it reduces the risk of oil spillage and minimizes the hassle of cleaning the surrounding area.

[0022] Furthermore, the housing is provided with an oil tray located below the baking pan, and the horizontal projection of the oil tray covers the horizontal projection of the oil leakage area.

[0023] By adopting the aforementioned technical solution, the horizontal projection of the oil-collecting tray covers the horizontal projection of the oil-leaking area of ​​the baking pan, ensuring that all the oil dripping from the oil-leaking area can be directly collected into the oil-collecting tray, thus avoiding the possibility of oil leakage or splashing.

[0036] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0037] like Figures 1 to 4 As shown, this utility model provides a deodorizing oven, including a spherical or nearly spherical shell, with a cooking cavity 20 inside the shell. The shell includes a lower shell 10 and an upper shell 11 located above the lower shell 10, forming the cooking cavity 20 between the lower shell 10 and the upper shell 11. The cooking cavity 20 is provided with a heating element 30, a baking tray 40, a fan assembly, and a deodorizing component 60. The heating element 30 is located in the upper half of the cooking cavity 20, i.e., the upper shell 11. The baking tray 40 is placed below the heating element 30. The deodorizing component 60 is located in the airflow path of the fan assembly. The fan assembly operates so that the fumes from the cooking cavity 20 pass through the deodorizing component 60.

[0038] When the size of the baking tray 40 is fixed, the upper and lower parts of the rectangular oven shell have the same or similar volume. In this embodiment, the upper and lower parts of the spherical or near-spherical shell have a smaller volume than the middle part, making the overall oven smaller and easier to store. By setting the deodorizing component 60 in the airflow path of the fan assembly, and the operation of the fan assembly, the oil fumes in the cooking cavity 20 can pass through the deodorizing component 60, which changes the existing situation where the baking tray 40 directly bakes without treating the oil fumes or the pseudo-smoke removal. It not only blows away the oil fumes, but also more effectively removes the oil fumes and odors produced by baking food, minimizing the odors floating in the oil fumes, thereby solving the problem of residual odors in the room caused by baking food as much as possible, and also reducing the impact of odors on the taste of baked food, improving the taste and appetite of baked food.

[0039] It should be noted that the fan assembly can be located upstream or downstream of the deodorizing component 60. The fan assembly includes a drive motor 51 and a fan 50 driven by the drive motor 51.

[0040] It should be noted that in this embodiment, the upper shell 11 is hemispherical, and the inner wall of the upper shell 11 is spherical. The lower shell 10 is partially spherical, making the cooking cavity 20 a nearly spherical (or near-spherical) space, thus increasing the oven's usable volume. The bottom surface of the lower shell 10 is flat, making the shell nearly spherical, allowing the oven to be placed stably on a horizontal surface. The baking tray 40 is positioned on the side of the upper shell 11 closest to the lower shell 10. Of course, in other embodiments, both the lower shell 10 and the upper shell 11 are hemispherical, making the shell spherical. The lower shell 10 is heavier than the upper shell 11, resulting in a lower center of gravity for the oven. The center of gravity of the oven is close to the center of the support surface of the lower shell 10. Under the action of gravity, the oven always ensures that the upper shell 11 is above and the lower shell 10 is below, with the baking tray 40 placed horizontally.

[0041] Furthermore, the cooking cavity 20 is provided with an airflow channel 21, and a fan assembly and a deodorizing component 60 are installed in the airflow channel 21. The upper port 22 of the airflow channel 21 is connected to the space above the baking pan 40 in the cooking cavity 20, and the lower port 23 of the airflow channel 21 is connected to the space below the baking pan 40 in the cooking cavity 20. This allows the oil fumes in the cooking cavity 20 to flow back to the space below the baking pan 40 after passing through the deodorizing component 60 under the drive of the fan assembly, forming a hot air circulation. This not only achieves efficient reuse and uniform distribution of heat, but also reduces heat loss and improves cooking efficiency and food quality. Under the same baking effect, the working time and power of the heating element 30 can be reduced, and the treatment effect of oil fumes and odors is greatly enhanced, providing a cleaner and odorless cooking environment.

[0042] Specifically, the airflow channel 21 includes airflow pipes respectively disposed on both sides of the heating element 30, which can more widely cover different areas within the cooking cavity 20, ensuring that the generated fumes are extracted and deodorized from more angles, further improving the deodorization effect and minimizing the problem of fumes lingering or insufficient purification in certain areas. The airflow pipes are arc-shaped and are disposed along the inner wall of the cooking cavity 20. Since different parts of the food produce different degrees of fumes and odors during the baking process, this application provides a knob 70 on the housing. The bottom of the airflow pipe is fixed to the knob 70. The knob 70 rotates relative to the housing to rotate the airflow pipe, thereby changing the position of the upper port 22 relative to the baking tray 40. By rotating the knob 70 to change the position of the upper port 22 of the airflow pipe relative to the baking tray 40, the odor concentration areas can be targeted for extraction, which helps to improve the deodorization efficiency and allows the odors in the oven to be removed more quickly and thoroughly.

[0043] It should be noted that the airflow duct is flat, and multiple through holes can be provided at the end and surface of the airflow duct to form the upper port 22, increasing the intake airflow and thus deodorizing more oil fumes. The fan assembly and deodorizing component 60 are housed inside the airflow duct, which also serves as heat insulation, effectively preventing the fan assembly from being exposed to high-temperature environments and ensuring the service life of the fan assembly.

[0044] It should be noted that the knob 70 remains fixed to the housing after rotation, thus maintaining the position of the airflow pipe. A friction pad with high friction is installed on the contact surface between the knob 70 and the housing. This friction pad generates sufficient friction to prevent the knob 70 from rotating further, thereby maintaining a fixed angle. When adjustment is needed, the friction of the friction pad must be overcome before the knob 70 can be rotated. Alternatively, in other embodiments, multiple evenly distributed slots and elastic pins are provided at corresponding positions on the knob 70 and the housing. When the knob 70 is rotated, the elastic pins slide between the slots. When the desired angle is reached, the elastic pins fall into the slots due to their elasticity. The resistance generated by the tight fit between the two prevents the knob 70 from rotating arbitrarily, thus fixing the current angle.

[0045] The deodorizing component 60 includes a heating plate 62 and a catalyst 61, with the heating plate 62 located upstream of the catalyst 61. The heating plate 62 preheats the odorous fumes entering the deodorizing component 60. After passing through the heating plate 62, the temperature of the fumes increases, and molecular motion intensifies. This allows the fumes to react more fully with the active sites on the surface of the catalyst 61 when they subsequently come into contact with it, improving catalytic efficiency and thus more effectively decomposing the fumes and volatile organic compounds. Furthermore, the catalyst 61 can only exert its optimal activity within a certain temperature range. Preheating the fumes by the heating plate 62 places the catalyst 61 in a more suitable operating temperature environment, thereby stimulating its activity and enabling it to more efficiently catalyze the decomposition of odorous substances, significantly enhancing the overall deodorizing capability of the deodorizing component 60.

[0046] It should be noted that the catalyst 61 may include a carrier and metal catalysts such as platinum and palladium disposed on the carrier. The cooking fumes in the cooking chamber 20 include gases such as VOCs. After being heated by the heating plate 62, the cooking fumes can be decomposed into water and carbon dioxide, which are smokeless, when passing through the catalyst 61. Of course, the catalyst 61 may also include a carrier and oxides, silicon dioxide, aluminum oxide, carbon, etc. disposed on the carrier, and is not limited to these.

[0047] Furthermore, the deodorizing component 60 is positioned close to the heating element 30. The heating element 30 emits a large amount of heat during operation, and the deodorizing component 60 can directly utilize this heat to activate the catalyst 61, enhancing its activity and purification effect, and strengthening its ability to remove fumes and odors. Even after the heating element 30 is turned off, there is still some residual heat. The deodorizing component 60 can make full use of this residual heat, allowing the deodorization reaction to continue at a relatively high temperature, accelerating the reaction rate and further improving deodorization efficiency. In this application, the upper port 22 of the airflow pipe is close to the heating element 30, and the deodorizing component 60 is positioned close to the upper port 22.

[0048] In existing technologies, the heating element 30 is typically positioned in a fixed location, resulting in uneven baking effects on different parts of the food. Therefore, in this application, the cooking cavity 20 is equipped with a slide rail 80 arranged along the circumference of the baking tray 40 towards the inner wall, and a drive slider 81 mounted on the slide rail 80. The heating element 30 is fixed to the drive slider 81, which drives the heating element 30 to move along the slide rail 80, allowing the heating element 30 to heat different positions within the cooking cavity 20. For example, when baking foods of different shapes and sizes, the heating element 30 can be moved to a better position to ensure even heating of all parts of the food, improving the cooking effect and minimizing the risk of localized burning or undercooking. The upper housing 11 also has an opening 13 for food to enter and exit. When not in use, the heating element 30 can be moved to a corner or other location for easy food handling and oven cleaning.

[0049] It should be noted that the power cord of the heating element 30 passes through the drive slider 81 and is mounted on the slide rail 80. The slide rail 80 is hollow inside to allow the power cord of the heating element 30 to pass through.

[0050] It should be noted that the sliding motion of the drive slider 81 is achieved under electromagnetic drive, primarily driven by a motor. The motor consists of a stator and a mover. When the motor is driven, a traveling wave magnetic field is generated when three-phase alternating current is applied to the stator windings. The mover is subjected to this magnetic field, generating electromagnetic force and moving. The drive slider 81 is fixedly connected to the mover, and the slide rail 80 defines the movement trajectory of the mover. Therefore, the drive slider 81 slides smoothly within the slide rail 80 along with the mover.

[0051] Furthermore, the central part of the baking pan 40 is raised upward relative to the surrounding parts, which allows excess oil to flow naturally to the surrounding oil draining area 41 due to gravity during cooking. This reduces the contact between food and oil, thus reducing the greasiness of the food. Since the distance between the raised part and the heat source is relatively shorter, heat can be transferred to all parts of the baking pan 40 more quickly, reducing the temperature difference between the center and the edge of the baking pan 40, and allowing the food to be heated more evenly during baking. Furthermore, the baking pan 40 has a recessed oil draining area 41 around its perimeter, which facilitates the collection of grease and food residue generated during cooking. These substances are concentrated in the oil draining area 41, minimizing spillage and making it easier to clean the surface of the baking pan 40. Finally, the outer ring of the baking pan 40 around the oil draining area 41 is tilted upwards, which effectively prevents grease from overflowing from the oil draining area 41 to the outside of the baking pan 40, avoiding soiling the surface of the oven and keeping the cooking environment clean. Even when moving the baking pan 40, the risk of grease spillage is reduced, and the hassle of cleaning the surrounding environment is decreased.

[0052] It should be noted that the baking pan 40 can be hat-shaped or ingot-shaped, and the heating element 30 can be circular. The heating element 30 is a heating tube capable of emitting infrared light waves. In this embodiment, the heating element 30 is shaped like a convex mirror. The convex mirror shape can reflect and scatter the emitted infrared light waves to a wider area. Compared with ordinary shaped heating tubes, it can cover a larger area of ​​the baking pan 40, allowing all the food on the baking pan 40 to be heated by infrared radiation, improving the overall heating uniformity and reducing local overheating or underheating. Of course, in other embodiments, since the heating element 30 is movable and the space of the cooking cavity 20 is fixed, the heating element 30 can also be shaped like a concave mirror. The heating element 30 fits more closely to the inner wall of the upper shell 11, making the space required for the heating element 30 to move smaller, thus allowing more space to place food.

[0053] Furthermore, the oil leakage area 41 has a perforation around the baking tray 40 for oil leakage. The housing has an oil collection tray 90 located below the baking tray 40. The horizontal projection of the oil collection tray 90 covers the horizontal projection of the oil leakage area 41, ensuring that all grease dripping from the oil leakage area 41 can be directly collected into the oil collection tray 90, avoiding the possibility of grease leakage or splashing. The housing may have an inlet / outlet 14 for the oil collection tray 90 to enter and exit, facilitating the removal and insertion of the oil collection tray 90.

[0054] It should be noted that in this embodiment, the oil tray 90 is disposed inside the lower housing 10.

[0055] It should be noted that the lower housing 10 is relatively sealed except for the space for the oil tray 90, to reduce the possibility of food falling into the lower housing 10. Of course, the lower housing 10 can also be square, and the oil tray 90 can be accessed through the drawer-like opening and closing entrance 14 for greater convenience.

[0056] Preferably, the oil leakage area 41 is 5cm away from the edge of the baking tray 40, and the diameter of the oil tray 90 can be 2cm larger than the diameter of the oil leakage area 41 to further avoid the possibility of oil leakage or splashing.

[0057] Understandably, in other embodiments, an airflow hood is provided inside the cooking cavity, conforming to the inner wall of the cooking cavity, forming an airflow channel between the airflow hood and the inner wall of the cooking cavity. The airflow hood can guide the fumes drawn by the fan assembly to flow along the inner wall of the cooking cavity, making the fumes form a more regular and stable flow path within the cooking cavity, avoiding turbulence and eddies in the fumes, resulting in smoother fume flow, reduced energy loss, and enabling the fan assembly to maintain the required fume flow rate and volume with lower power. The low-resistance airflow channel also helps to reduce noise generation, creating a quiet cooking environment for the user.

[0058] Understandably, in other embodiments, the heating element can heat different positions within the arc-shaped cooking cavity. An annular track is provided around the upper shell, and rollers are provided around the lower shell. These rollers are driven by a motor to rotate the upper shell relative to the lower shell. When the upper shell rotates relative to the lower shell, the food within the cooking cavity receives heat from the heating element as comprehensively as possible, thus minimizing the uneven heating problems that may occur in traditional ovens due to fixed-position heating. The rotation of the upper shell relative to the lower shell also promotes airflow circulation within the cooking cavity, creating a more uniform temperature field. Alternatively, in other embodiments, an annular track is provided around the lower shell, and rollers are provided around the upper shell, with the rollers driven by a motor to rotate the upper shell relative to the lower shell.

[0059] Understandably, in other embodiments, the heating element is fixed to the upper housing and located on a side of the upper housing offset from its vertical axis. A ring track is provided around the upper housing, and rollers are provided around the lower housing. These rollers are driven by a motor to rotate the upper housing relative to the lower housing. When the upper housing rotates relative to the lower housing, the heating element heats the food in the cooking cavity as evenly as possible, creating a more uniform temperature field and thus minimizing the uneven heating problems that may occur in traditional ovens. Alternatively, in other embodiments, a ring track is provided around the lower housing, and rollers are provided around the upper housing, with the rollers driven by a motor to rotate the upper housing relative to the lower housing.

[0060] Example 2:

[0061] like Figure 5As shown, in this embodiment, the housing is provided with an exhaust port 12, and the cooking cavity 20 is provided with an airflow channel 21. The fan assembly and the deodorizing component 60 are disposed in the airflow channel 21. The upper port 22 of the airflow channel 21 is connected to the space above the baking tray 40 in the cooking cavity 20, and the lower port 23 of the airflow channel 21 is connected to the exhaust port 12, so that the oil fumes in the cooking cavity 20 are discharged from the exhaust port 12 after passing through the deodorizing component 60 under the drive of the fan assembly. This avoids excessive accumulation of hot air in the cooking cavity 20 as much as possible, helps to maintain the stability of the oven temperature, makes the baking process more stable and controllable, and prevents the food quality from being adversely affected by excessively high temperature, such as avoiding the food from burning or drying out.

[0062] It should be noted that in this embodiment, the exhaust port 12 is provided on the upper housing 11.

[0063] Understandably, in other embodiments, the exhaust port can also be located on the lower housing. Since most components, such as the heating element, are located on the upper housing, while the lower housing has fewer components, placing the lower end of the airflow channel and the exhaust port on the lower housing reduces the space occupied inside the upper housing, allowing for a more rational arrangement of components. Of course, exhaust ports can also be provided on both the upper and lower housings simultaneously to increase exhaust capacity and make the airflow in the airflow channel smoother.

[0064] Other content not described in this embodiment can be referred to in the above embodiments.

[0065] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
