[0006] Optionally, the air hood also includes auxiliary plates disposed on opposite sides of the main board, and the auxiliary plates and side plates are located on adjacent sides of the main board; a second auxiliary air outlet is provided on one side of the auxiliary plate, and a third auxiliary air outlet is provided on the other side of the auxiliary plate, the distance between the first auxiliary air outlet and the return air outlet is less than the distance between the second auxiliary air outlet and the return air outlet, and the distance between the first auxiliary air outlet and the return air outlet is less than the distance between the third auxiliary air outlet and the return air outlet.

[0007] Optionally, the motherboard body has different first reference directions and second reference directions.

[0008] Optionally, two sets of second auxiliary air outlets are provided, with the two sets of second auxiliary air outlets respectively located on both sides of the auxiliary plate in the first reference direction; the third auxiliary air outlet is located in the middle of the auxiliary plate in the first reference direction.

[0009] Optionally, the main board has two air outlets spaced apart, and the air outlet blades corresponding to the two air outlets are arranged in opposite directions. The second auxiliary air outlet is located on the auxiliary board in which the rotation direction of the air outlet blades points to the tangential direction on the side opposite to the two air outlets. The third auxiliary air outlet is located on the auxiliary board in which the rotation direction of the air outlet blades points to the tangential direction on the side close to the two air outlets.

[0010] Optionally, a fourth auxiliary air outlet is also provided on the motherboard body. The fourth auxiliary air outlet is located on the side of the return air outlet in the second reference direction that is close to the third auxiliary air outlet.

[0014] Secondly, embodiments of this application provide a cooking device. The cooking device includes a main body and the aforementioned air outlet shroud, the air outlet shroud being installed on the main body.

[0015] The beneficial effects of this application are as follows: Unlike existing technologies, by setting a return air vent on the main body and an air outlet on the side plate, the cooking device can generate airflow circulation within the cooking cavity under the action of the air outlet blades, thereby promoting heat circulation within the cooking cavity and achieving the purpose of cooking food. Specifically, the airflow can be directed into the cooking cavity through the first auxiliary air outlet, and the airflow within the cooking cavity can be returned through the return air vent. The airflow direction at the first auxiliary air outlet is opposite to the airflow direction at the return air vent, and the first auxiliary air outlet and the return air vent are relatively close. In this case, the opposite airflow direction can create a suction effect in the area near the main body within the cooking cavity, thereby creating a low-pressure zone in this area. This allows the airflow to move towards this low-pressure zone, thus improving the uniformity of airflow within the cooking cavity. Attached Figure Description

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0024] Combination Figures 1 to 2 This application provides a cooking device 1. The cooking device 1 provided in this application embodiment can be a microwave oven, oven, or steam oven. The cooking device 1 provided in this application embodiment can also be an integrated machine combining any two of the three functions of microwaving, steaming, or baking. The cooking device 1 provided in this application embodiment can also be a microwave-steam-bake integrated machine. The cooking device 1 includes a main body 10, an air outlet assembly 20, and an air outlet hood 30.

[0025] Specifically, the main body 10 can install and support various components. Depending on the type of cooking device 1, the main body 10 can support microwave components, steam components, or heating components, etc. The main body 10 has a cooking cavity 101. The cooking cavity 101 can be used to place food and can contain microwaves, steam, or hot air to heat the food. Optionally, the two ends of the main body 10 have openings that communicate with the cooking cavity 101 respectively. One opening on one side of the main body 10 can be used to install a door (not shown), which can open or close the opening, allowing a user to put or take food into or out of the cooking cavity 101 through the opening. The opening on the other side of the main body 10 can be used to install an exhaust hood 30 and an exhaust assembly 20. The exhaust hood 30 and the exhaust assembly 20 can cooperate to generate airflow within the cooking cavity 101 to achieve uniform heating of the food.

[0026] In some embodiments, a recessed portion 11 is provided on one side of the main body 10 facing the cooking cavity 101. The recessed portion 11 can accommodate components such as microwave components, steam components, or heating components. The recessed portion 11 allows the size of components such as microwave components, steam components, or heating components to be partially accommodated in the cooking cavity 101, thereby reducing the overall space occupied by the cooking device 1.

[0027] The air outlet assembly 20 is installed on the main body 10 of the equipment. The air outlet assembly 20 can discharge air into the cooking cavity 101 through the air outlet cover 30. The air outlet assembly includes a fixed cover, a bracket, a drive unit, and air outlet blades. The drive unit can be fixed to the fixed cover via the bracket. The air outlet blades are driven and connected to the drive unit. The air outlet blades can generate airflow by rotating. The airflow generated by the air outlet blades can be guided into the cooking cavity 101 through the air outlet cover 30.

[0028] An air hood 30 is installed on the main body 10 of the device and communicates with the cooking cavity 101. The air hood 30 is installed at one end of the main body 10 with an opening. The air hood 30 is provided with an air outlet 321, through which the airflow generated by the air outlet assembly 20 can enter the cooking cavity 101. The air hood 30 can rectify and guide the airflow generated by the air outlet assembly 20, and then guide the airflow into the cooking cavity 101. The air hood 30 can also form a return air inlet 311 corresponding to the air outlet assembly 20, through which the airflow in the cooking cavity 101 can flow back to the air outlet blades. In this way, airflow circulation can be formed in the cooking cavity 101, thereby promoting the flow of heat in the cooking cavity 101 and improving the uniformity of heating of food inside the cooking cavity 101.

[0029] In some embodiments, combined with Figure 2 The main body 10, air outlet hood 30, and air outlet assembly 20 are separately configured. The main body 10 can be used to install the air outlet hood 30 and the air outlet assembly 20. The air outlet assembly 20 can drive airflow convection through the rotation of the air outlet blades. The air outlet hood 30 can integrate and guide the airflow, thereby inputting it into the cooking cavity 101 in a desired manner. By setting the main body 10, air outlet hood 30, and air outlet assembly 20 separately, different air outlet hoods 30 and air outlet assemblies 20 can be selected and equipped during the assembly process. By selecting different air outlet hoods 30 and air outlet assemblies 20, cooking equipment 1 with different configurations can be assembled.

[0030] In some embodiments, the cooking device 1 further includes air outlet blades corresponding to the return air vent 311 of the air outlet hood 30, and the air outlet blades are configured to switch their rotation direction. The air outlet blades generate airflow in different directions when rotating clockwise and counterclockwise, thereby affecting the state of the airflow introduced into the cooking cavity 101. By setting the rotation direction of the air outlet blades to be changeable, the airflow state within the cooking cavity 101 can be altered according to specific circumstances or different structures at the air outlet 321 (described later), thereby improving the uniformity of the airflow.

[0031] Combination Figures 3 to 5 This application provides an air outlet cover 30. The air outlet cover 30 includes a main body 31 and a side plate 32. The main body 31 is provided with a return air port 311. The side plate 32 is disposed on at least one side of the main body 31 and is connected to the main body 31. The side plate 32 is provided with an air outlet 321. Through the air outlet 321 of the side plate 32, airflow generated by the air outlet blades of the cooking device 1 can be introduced into the cooking cavity 101, and through the return air port 311 of the main body 31, the airflow in the cooking cavity 101 can flow back to the air outlet blades from the return air port 311. In this way, airflow circulation can be formed in the cooking cavity 101.

[0032] For ease of description, the mainboard body 31 has different first reference directions (illustrated in conjunction with the X direction in the figure) and second reference directions (illustrated in conjunction with the Y direction in the figure). At least one side of the mainboard body 31 in the second reference direction is configured to correspond to the side of the device body 10 where the recessed portion 11 is located. Optionally, the first reference direction is the length direction of the mainboard body 31, and the second reference direction is the width direction of the mainboard body 31. Optionally, the first and second reference directions are perpendicular. Optionally, when the cooking device 1 is in use, the second reference direction is parallel to the direction of gravity.

[0033] In some embodiments, the air outlet 321 has a first direction and a second direction. The first direction and the second direction can be orthogonal. For example, the first direction can be the length direction of the air outlet 321, and the second direction can be the width direction of the air outlet 321. In other embodiments, the first direction can be the width direction of the air outlet 321, and the second direction can be the length direction of the air outlet 321. Optionally, the shape of the air outlet 321 can be rectangular, elliptical, or rhomboid, etc.

[0034] Combination Figures 3 to 5In some embodiments, the air outlet 321 has a first direction and a second direction. A guide vane is provided on one side of the air outlet 321 in the second direction. The guide vane can guide the airflow blown out of the air outlet 321. By providing the guide vane, the airflow of the air outlet 321 can be directed towards the front side of the main body 31. In other words, the guide vane can cooperate with the air outlet 321 to change the direction of the airflow, thereby improving the uniformity of the airflow inside the cooking cavity 101. Optionally, in the second direction, the guide vane is provided on the side of the air outlet 321 away from the main body 31.

[0035] In some embodiments, the air outlet 321 is inclined relative to a first reference direction in a first direction. The main body 31 has opposing front and rear sides in its thickness direction, and the side plate 32 is inclined rearward from the outer edge of the main body 31 in a direction away from the main body 31.

[0036] In some embodiments, combined with Figure 4 and 5 The guide vanes extend obliquely from the edge of the air outlet 321 away from the side plate 32 towards the center of the air outlet 321. In other words, the guide vanes on both sides of the air outlet 321 extend obliquely from the side plate 32 towards each other. The projection of the guide vanes onto the side plate 32 covers at least a portion of the air outlet 321. In this way, the airflow blowing out of the air outlet 321 can be directly blocked by the guide vanes, thereby changing the direction of the airflow.

[0037] Combination Figure 3 This application embodiment provides an air outlet hood 30. A first auxiliary air outlet 312 is also provided on the main board 31. The distance between the first auxiliary air outlet 312 and the return air outlet 311 is less than the distance between the air outlet 321 and the return air outlet 311. Airflow can be directed towards the cooking cavity 101 through the first auxiliary air outlet 312, and airflow within the cooking cavity 101 can return through the return air outlet 311. The airflow direction at the first auxiliary air outlet 312 is opposite to the airflow direction at the return air outlet 311. Furthermore, the first auxiliary air outlet 312 and the return air outlet 311 are relatively close. In this case, the opposite airflow direction can create a suction effect in the area near the main board 31 within the cooking cavity 101, thereby creating a low-pressure area in the area near the main board 31 of the cooking cavity 101. This allows the airflow to move closer to the low-pressure area, thereby improving the uniformity of airflow within the cooking cavity 101 to compensate for heat exchange in the area near the main board 31. Furthermore, the above method has less impact on the area of ​​the cooking cavity 101 away from the main board 31, thus taking into account both the area near and away from the main board 31 within the cooking cavity 101.

[0038] In some embodiments, a plurality of first auxiliary air outlets 312 constitute a group, and the plurality of groups of first auxiliary air outlets 312 are arranged at intervals on the outer periphery of the return air outlet 311. The first auxiliary air outlets 312 can be circular, elliptical, rhomboid, or strip-shaped, etc., without specific limitation. Different first auxiliary air outlets 312 can have different shapes. By setting, for example, at least two groups of first auxiliary air outlets 312, multiple low-pressure areas can be formed in the area near the air outlet hood 30 in the cooking cavity 101, thereby further compensating for heat exchange in the area of ​​the cooking cavity 101 near the main body 31 in the aforementioned manner. On the other hand, the cooking cavity 101 may have multiple layers of different heating areas. By arranging multiple groups of first auxiliary air outlets 312 at intervals on the outer periphery of the return air outlet 311, while taking into account the distance between the first auxiliary air outlets 312 and the return air outlet 311, different groups of first auxiliary air outlets 312 correspond to different layers of the cooking cavity 101, thereby effectively compensating for heat exchange in each layer of the cooking cavity 101 near the main body 31.

[0039] In some embodiments, the first auxiliary air outlet 312 is located between the side panel 32 and the return air outlet 311. Specifically, it can be located between the central axis of the return air outlet 311 and the side panel 32. In other embodiments, the first auxiliary air outlet 312 may also be located between two return air outlets 311.

[0040] Combination Figures 3 to 5 In some embodiments, the air hood 30 further includes auxiliary plates 33 disposed on opposite sides of the main body 31, with the auxiliary plates 33 and side plates 32 located on adjacent sides of the main body 31. One auxiliary plate 33 has a second auxiliary air outlet 331, and the other auxiliary plate 33 has a third auxiliary air outlet 332. By providing the second and third auxiliary air outlets 331 and 332, the air outlet area of ​​the air hood 30 can be increased, improving the airflow distribution in the cooking cavity 101. Furthermore, by making the distance between the first auxiliary air outlet 312 and the return air outlet 311 smaller than the distance between the second auxiliary air outlet 331 and the return air outlet 311, and the distance between the first auxiliary air outlet 312 and the return air outlet 311 smaller than the distance between the third auxiliary air outlet 332 and the return air outlet 311, the influence of the second and third auxiliary air outlets 331 and 332 on the first auxiliary air outlet 312 can be reduced.

[0041] In some embodiments, the auxiliary plate 33 is disposed on opposite sides of the main plate 31 in the second reference direction.

[0042] In some embodiments, two sets of second auxiliary air outlets 331 are provided, with the two sets of second auxiliary air outlets 331 respectively disposed on both sides of the auxiliary plate 33 in the first reference direction. A third auxiliary air outlet 332 is disposed in the middle of the auxiliary plate 33 in the first reference direction. The auxiliary plate 33 is respectively disposed on both sides of the return air inlet 311, and the air outlet blades corresponding to the return air inlet 311 generate airflow directions in different directions during rotation. By configuring the second auxiliary air outlets 331 and the third auxiliary air outlet 332 in the above manner, they can be matched with the airflow directions generated by the air outlet blades, so that the second auxiliary air outlets 331 and the third auxiliary air outlet 332 have a wider air outlet area.

[0043] In some embodiments, the main body 31 is provided with two air outlets 321 spaced apart, and the air outlet blades corresponding to the two air outlets 321 are arranged in opposite directions. The second auxiliary air outlet 331 is located on the auxiliary body 33 to which the tangential direction of the air outlet blades points on the side opposite to the two air outlets 321. The third auxiliary air outlet 332 is located on the auxiliary body 33 to which the tangential direction of the air outlet blades points on the side close to the two air outlets 321.

[0044] by Figure 3 Taking the air outlet hood 30 in the figure as an example, the air outlet hood 30 has two return air inlets 311. Taking the air outlet blade corresponding to the left return air inlet 311 rotating clockwise and the air outlet blade following the right return air inlet 311 rotating counterclockwise as an example, the spacing direction of the two sets of second auxiliary air outlets 331 is also the spacing direction of the return air inlets 311. When the air outlet blades rotate clockwise to the left and counterclockwise to the right, the tangential direction of the opposite sides of the return air inlets 311 is upward. The airflow direction driven by the rotation of the air outlet blades can correspond to the second auxiliary air outlets 331 arranged on both sides on the upper auxiliary plate 33, so that the air outlets of the second auxiliary air outlets 331 can cover a wider area of ​​the cooking cavity 101 (in conjunction with...). Figure 6 (Airflow diagram). The tangential direction of the return air vent 311 on both sides is downward, and the airflow direction driven by the rotation of the air outlet blades can correspond to the third auxiliary air outlet 332 located in the middle of the lower auxiliary plate 33, so that the air outlet of the third auxiliary air outlet 332 can cover a wider area of ​​the cooking cavity 101 (in conjunction with...). Figure 7 (Diagram of airflow in the middle).

[0045] In some embodiments, the mainboard body 31 is further provided with a fourth auxiliary air outlet 313. The fourth auxiliary air outlet 313 is located on the side of the return air outlet 311 near the third auxiliary air outlet 332 in the second reference direction. The fourth auxiliary air outlet 313 is located in the middle of the mainboard body 31 in the first reference direction, and the fourth auxiliary air outlet 313 is correspondingly arranged with the third auxiliary air outlet 332. The fourth auxiliary air outlet 313 can cooperate with the third auxiliary air outlet 332 to further expand the coverage area of ​​the airflow in the cooking cavity 101.

[0046] In some embodiments, the side plate 32 is disposed on the adjacent side of the main plate 31 and the recessed portion 11. The first direction of the air outlet 321 is inclined away from the recessed portion 11 in the direction away from the main plate 31. In this way, the side plate 32 with the air outlet 321 can bypass the obstruction of the recessed portion 11, so that the airflow of the air outlet 321 can be smoothly discharged into the cooking cavity 101, thereby promoting the flow of air in the cooking cavity 101 and improving the uniformity of airflow. Optionally, the side plate 32 is disposed on at least one side in the first reference direction. The side plate 32 being disposed on one side in the first reference direction can bypass the recessed portion 11 disposed on the second reference direction side, thereby helping to improve the uniformity of airflow.

[0047] In some embodiments, the auxiliary plate 33 with the second auxiliary air outlet 331 is disposed on the side of the main plate 31 corresponding to the recessed portion 11. In this way, the second auxiliary air outlet 331 can avoid the influence of the recessed portion 11 on the airflow as much as possible, thereby improving the uniformity of airflow in the cooking cavity 101.

[0048] The above are merely embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
