[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] In some embodiments, a guide vane 322 is provided on one side of the air outlet 321 in the second direction. The rotation direction of the air outlet blades corresponding to the return air outlet 311 is tangential to the position near the side plate 32. In the tangential direction, the air outlet 321 has a first side and a second side in sequence, and the guide vane 322 is provided on at least the second side in the tangential direction.

[0032] By providing a return air vent 311 on the main body 31 and an air outlet vent 321 on the side panel 32, the cooking device 1 can generate airflow circulation within the cooking cavity 101 under the action of the air outlet blades, thereby promoting heat circulation within the cooking cavity 101 and achieving the purpose of cooking food. Furthermore, by positioning the guide plate 322 on the second side in the tangential direction, the placement of the guide plate 322 can be matched with the rotation direction of the air outlet blades, effectively guiding the airflow into the cooking cavity 101.

[0033] 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 in a direction away from the main body 31, the side plate 32 is inclined rearward from the outer edge of the main body 31. On the side plate 32, a guide plate 322 is provided on one side of the air outlet 321 in a second direction (further combined with...). Figure 6The deflector 322 guides the airflow from the outlet 321. By setting the deflector 322, the airflow from the outlet 321 can be directed towards the front of the main body 31. In other words, the deflector 322 can work with the outlet 321 to change the direction of the airflow, thereby improving the uniformity of airflow inside the cooking cavity 101. Optionally, the projection of the deflector 322 on the side panel 32 covers at least a portion of the outlet 321.

[0034] Furthermore, at least one of the air outlets 321 has a tangent in the rotational outer diameter of the air outlet blade corresponding to the return air outlet 311 in the second direction. In this way, the arrangement of the guide plate 322 can be further matched with the rotational direction of the air outlet blade, thereby effectively guiding the airflow to the cooking cavity 101.

[0035] It should be noted that the airflow direction generated by the rotation of the exhaust blades is not perpendicular to the extension direction of the side plate 32. Furthermore, the airflow direction generated by the exhaust blades is related to the rotation direction of the exhaust blades. Specific details are described below.

[0036] In some embodiments, two side plates 32 are respectively disposed on both sides of the main body 31 in the first reference direction. The air outlet hood 30 has a return air vent 311. When viewed from the front side of the air outlet hood 30, the guide plate 322 on one side plate 32 is disposed on the side of the air outlet 321 away from the main body 31, and the guide plate 322 on the other side plate 32 is disposed on the side of the air outlet 321 close to the main body 31.

[0037] With reference to specific embodiments, see Figure 3 With the air outlet blades rotating counterclockwise, the airflow direction for the left side panel 32 is downward to the left. The rotation direction of the air outlet blades is downward in the tangential direction near the side panel 32. The guide plate 322 needs to be positioned on the lower side of the air outlet 321 to effectively guide the airflow to the cooking cavity 101. That is, in the downward tangential direction, the lower side of the air outlet 321 is the second side.

[0038] Combination Figure 3 With the air outlet blades rotating counterclockwise, the airflow direction for the right-side side panel 32 is upward and to the right. The rotation direction of the air outlet blades is upward in the tangential direction near the side panel 32. The guide plate 322 needs to be positioned on the upper side of the air outlet 321 to effectively guide the airflow to the cooking cavity 101. That is, in the upward tangential direction, the upper side of the air outlet 321 is the second side.

[0039] Combination Figure 3The cooking device 1 may include only one air outlet blade, and the air outlet hood 30 is provided with a return air vent 311. The air outlet blade and the return air vent 311 are correspondingly arranged. Side plates 32 are respectively provided on both sides in the first reference direction, and air outlets 321 are opened on the side plates 32. In this case, one side of the air outlet blade is respectively provided on both sides of the side plate 32. Since the tangential directions on both sides of the air outlet blade are opposite, the guide plate 322 on one side plate 32 is located on the upper side in the width direction of the air outlet 321, while the guide plate 322 on the other side plate 32 is located on the lower side in the width direction of the air outlet 321. Optionally, "upper" may refer to one side in the second reference direction, and "lower" may refer to the other side in the second reference direction. 。

[0040] In some embodiments, two side plates 32 are respectively disposed on both sides of the main plate 31 in the first reference direction, and the air outlet hood 30 has two return air ports 311. The rotation directions of the air outlet blades corresponding to the two return air ports 311 are opposite. When viewed from the front side of the air outlet hood 30, the air outlets 321 disposed on the two side plates 32 are symmetrically arranged, and the guide plates 322 disposed on the two side plates 32 are symmetrically arranged relative to the main plate 31.

[0041] Combination Figure 4 The cooking device 1 may include two air outlet blades. The main body 31 includes two return air inlets 311, and the two air outlet blades are correspondingly arranged with the two return air inlets 311. Side plates 32 are respectively provided on both sides in the first reference direction, and air outlets 321 are opened on the side plates 32. In this case, the rotation direction of the two air outlet blades can be selected to be opposite ( Figure 4 As shown, for example, left is clockwise and right is counterclockwise. Thus, the air outlet blades face the same direction in the tangential direction of the side plates 32 that are close to both sides. The guide plates 322 on both side plates 32 are set on the same side in the width direction of the air outlet 321 (either near the top or near the bottom).

[0042] In some embodiments, two side plates 32 are respectively disposed on both sides of the main plate 31 in the first reference direction. The air outlet hood 30 has two return air ports 311. The air outlet blades corresponding to the two return air ports 311 rotate in the same direction. When viewed from the front side of the air outlet hood 30, the guide plate 322 on one side plate 32 is disposed on the side of the air outlet 321 away from the main plate 31, and the guide plate 322 on the other side plate 32 is disposed on the side of the air outlet 321 close to the main plate 31.

[0043] Combination Figure 5The cooking device 1 may include two air outlet blades. The main body 31 includes two return air inlets 311, and the two air outlet blades are correspondingly arranged with the two return air inlets 311. Side plates 32 are respectively arranged on both sides in the first reference direction, and air outlets 321 are opened on the side plates 32. In this case, the rotation direction of the two air outlet blades can also be the same (both clockwise or both counterclockwise). Thus, the tangential directions of the air outlet blades near the two sides of the side plates 32 are opposite. Therefore, the guide plate 322 on one side plate 32 is arranged on one side of the air outlet 321 in the width direction, which is higher, while the guide plate 322 on the other side plate 32 is arranged on the other side of the air outlet 321 in the width direction, which is lower.

[0044] 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.

[0045] 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.
