DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] Combination Figure 1 to Figure 2 , the embodiment of the present application provides a cooking device 1. The cooking device 1 provided in the embodiment of the present application may be a microwave oven, an oven or a steamer. The cooking device 1 provided in the embodiment of the present application may also be an all-in-one machine integrating any two of the three functions of microwave, steam or bake. The cooking device 1 provided in the embodiment of the present application may also be a microwave, steam and bake all-in-one machine. The cooking device 1 includes a device body 10, an air outlet component 20 and an air outlet hood 30.

[0019] Specifically, the device body 10 can be installed and carry various components. Depending on the type of the cooking device 1, the device body 10 can carry a microwave component, a steam component or a heating component, etc. The device body 10 has a cooking cavity 101. The cooking cavity 101 can be used to place food, and can accommodate microwaves, steam or hot air to heat the food. Optionally, both ends of the device body 10 have openings that are respectively connected to the cooking cavity 101. The opening on one side of the device body 10 can correspond to the installation of a door body (not shown in the figure), and the door body can open or close the opening, allowing the user to put in or take out food into the cooking cavity 101 through the opening. The opening on the other side of the device body 10 can correspond to the installation of an air hood 30 and an air outlet assembly 20. The air hood 30 and the air outlet assembly 20 can cooperate to generate airflow in the cooking cavity 101 to achieve uniform heating of the food.

[0020] In some embodiments, a sinking portion 11 is provided on one side of the device body 10 toward the cooking cavity 101. The sinking portion 11 can be used to install components such as a microwave component, a steam component, or a heating component. The provision of the sinking portion 11 can allow the size of components such as a microwave component, a steam component, or a heating component to be partially accommodated by the cooking cavity 101, thereby reducing the overall occupied space of the cooking device 1.

[0021] Combination Figure 2 The air outlet assembly 20 is installed on the device body 10. The air outlet assembly 20 can discharge air into the cooking cavity 101 through the air outlet cover 30. The air outlet assembly 20 includes a fixed cover, a bracket, a driving device and an air outlet blade. The driving device can be fixed to the fixed cover through the bracket. The air outlet blade is connected to the driving device. The air outlet blade can generate airflow by rotating. The airflow generated by the air outlet blade can be guided into the cooking cavity 101 through the air outlet cover 30.

[0022] The air outlet hood 30 is installed on the device body 10 and is connected to the cooking cavity 101. The air outlet hood 30 is installed at one end of the device body 10 having an opening. The air outlet hood 30 is provided with an air outlet 321, and the airflow generated by the air outlet assembly 20 can enter the cooking cavity 101 from the air outlet 321. The air outlet hood 30 can rectify and guide the airflow formed by the air outlet assembly 20, and then guide the airflow into the cooking cavity 101. The air outlet hood 30 can also form a return air port 311 corresponding to the air outlet assembly 20, and the airflow in the cooking cavity 101 can flow back from the return air port 311 to the air outlet blades. In the above manner, an airflow circulation can be formed in the cooking cavity 101, thereby promoting the flow of heat in the cooking cavity 101, so as to improve the uniformity of heating the food inside the cooking cavity 101.

[0023] In some embodiments, in combination Figure 2 , the device body 10, the air hood 30 and the air outlet assembly 20 are separately arranged. The device body 10 can be used to install the air hood 30 and the air outlet assembly 20. The air outlet assembly 20 can drive air convection by rotating the air outlet blades. The air outlet hood 30 can integrate and guide the airflow so as to input it into the cooking cavity 101 in a desired manner. By arranging the device body 10, the air outlet hood 30 and the air outlet assembly 20 separately, the device body 10 can be equipped with different air hoods 30 and air outlet assemblies 20 during the assembly process. By selecting different air hoods 30 and air outlet assemblies 20, cooking devices 1 with different configurations can be assembled.

[0024] In some embodiments, there are multiple air outlet hoods 30, and there are also multiple air outlet assemblies 20. The air outlet hood 30 may include an air outlet hood 30 provided with a single return air port 311 or an air outlet hood 30 provided with multiple return air ports 311. The air outlet hood 30 may also include an air outlet hood 30 provided with air outlets 321 of different forms. The air outlet assembly 20 may include a single fan assembly or a double fan assembly, etc. The device body 10 is a universal cavity. The device body 10 has the same assembly method with different air outlet hoods 30. The device body 10 also has the same assembly method with different air outlet assemblies 20. In this way, the cooking device 1 can be equipped with air outlet hoods 30 and air outlet assemblies 20 of different configurations. For example, during the assembly process, the air outlet assembly 20 of the double fan and the air outlet hood 30 of the double return air port 311 can be installed on the device body 10 according to the different configurations required; or the air outlet assembly 20 of the single fan and the air outlet hood 30 of the single return air port 311 can be installed.

[0025] In the related art, a sinking portion 11 is provided on one side of the device body 10 toward the cooking cavity 101. The sinking portion 11 can be used to install components such as a microwave component, a steam component or a heating component. The setting of the sinking portion 11 will hinder the air outlet of the air outlet hood 30, resulting in a decrease in the uniformity of the air flow in the cooking cavity 101. In order to improve the above technical problems, the present application can provide the following embodiments.

[0026] It should be noted that the embodiment provided by the present application also has the technical effect of improving the uniformity of airflow without the sinking part 11. The present application has made a targeted design for the case with the sinking part 11. Compared with the solutions in the related art, the embodiment of the present application has a better effect of improving the uniformity of airflow for the case with the sinking part 11.

[0027] Reference Figures 3 to 11 As shown in the figure, an embodiment of the present application provides an air outlet hood 30. The air outlet hood 30 includes a main board body 31 and a side board body 32. The main board body 31 is provided with a return air port 311. The side board body 32 is arranged on at least one side of the main board body 31, and the side board body 32 is connected to the main board body 31. Among them, the side board body 32 is provided with an air outlet 321. The air outlet 321 of the side board body 32 can introduce the airflow generated by the air outlet blades of the cooking device 1 into the cooking cavity 101, and the airflow in the cooking cavity 101 can flow back from the return air port 311 to the air outlet blades through the return air port 311 of the main board body 31. In the above manner, an airflow circulation can be formed in the cooking cavity 101.

[0028] For the convenience of description, the main board body 31 has different first reference directions (in combination with the schematic diagram of the X direction in the figure) and second reference directions (in combination with the schematic diagram of the Y direction in the figure). At least one side of the main board body 31 in the second reference direction is configured to correspond to the side of the device body 10 provided with the sinking part 11. Optionally, the first reference direction is the length direction of the main board body 31, and the second reference direction is the width direction of the main board body 31. Optionally, the first reference direction and the second reference direction are perpendicular. Optionally, when the cooking device 1 is in use, the second reference direction is parallel to the gravity direction.

[0029] Combination Figure 2 , Figure 3 , Figure 4 , Figure 6 and Fig. 9 In this embodiment, the side plate 32 is disposed on the adjacent side of the main plate 31 corresponding to the side of the sinking portion 11. In this way, the side plate 32 with the air outlet 321 can bypass the shielding of the sinking 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 the airflow.

[0030] The air outlet 321 has a length direction and a width direction, and the length direction of the air outlet 321 is inclined relative to the first reference direction. In other words, the length direction of the air outlet 321 is set at an angle with the first reference direction. Through the inclination of the air outlet 321, in the direction away from the main board body 31, the outlet position of the airflow will gradually move away from one side of the main board body 31, thereby reducing the influence of the components corresponding to the side on the air outlet.

[0031] Specifically, the length direction of the air outlet 321 is inclined toward one side of the second reference direction in the direction away from the main body 31. Specifically, the end of the air outlet 321 close to the main body 31 is closer to the sinking part 11 than the end of the air outlet 321 far from the main body 31. In the cooking device 1, the length direction of the air outlet 321 is inclined toward the side away from the sinking part 11 in the direction away from the main body 31. In this way, the air outlet position can be gradually moved away from the sinking part 11 in the direction away from the main body 31, thereby reducing the obstruction of the airflow by the sinking part 11.

[0032] Furthermore, the direction of the airflow generated by the air outlet blades during the rotation process is not perpendicular to the extension direction (second reference direction) of the side plate 32. The direction of the airflow generated by the air outlet blades will be tilted at a certain angle to blow toward the side plate 32. By tilting the length direction of the air outlet 321, the direction of the air outlet 321 can be matched with the direction of the airflow generated by the air outlet blades, so that the airflow can be more conveniently directed into the cooking cavity 101.

[0033] In some embodiments, in combination Figure 8 The side plate 32 has an air outlet area. The air outlet area can be the entire side plate 32, or it can be an area for opening an air outlet 321 formed by sheet metal or bending of the side plate 32, which is not specifically limited here. Optionally, the air outlet area can also be an area formed by the air outlet 321 at one end of the side plate 32 extending to the air outlet 321 at the other end.

[0034] Combination Figure 8 , multiple air outlets 321 are arranged at intervals in the air outlet area, the angle of inclination of the air outlet 321 relative to the first reference direction is ∠A, and the angle between the line connecting the geometric center of the air outlet area and the geometric center of the return air outlet 311 and the first reference direction is ∠D. The angle between the line connecting the geometric center of the air outlet area and the geometric center of the return air outlet 311 and the tangent line of the geometric center of the air outlet area and the outer edge of the return air outlet 311 is ∠C. The above parameters satisfy .

[0035] Specifically, ∠C and ∠D can be calculated by trigonometric functions based on various dimensions. For example, the distance between the geometric center of the air outlet area and the projection of the geometric center of the return air outlet 311 in the second reference direction is H, the distance between the geometric center of the air outlet area and the projection of the geometric center of the return air outlet 311 in the first reference direction is L, and the radius of the return air outlet 311 is r. In this case, the above parameters satisfy The above method can match the inclination angle of the air outlet 321 with the position of the return air outlet 311. Since the return air outlet 311 is arranged correspondingly to the air outlet blade, the above method can match the inclination angle of the air outlet 321 with the position of the air outlet blade, so that the air outlet 321 can more effectively discharge the airflow generated by the air outlet blade to the cooking cavity 101.

[0036] In some embodiments, a plurality of air outlets 321 are disposed on the side plate 32 , and the plurality of air outlets 321 are spaced apart in the second reference direction, and length directions of the plurality of air outlets 321 are parallel to each other.

[0037] In some embodiments, the main body 31 has a front side and a rear side relative to each other in the thickness direction thereof, and the side plate 32 is arranged to be inclined from the outer edge of the main plate 31 to the rear side in the direction away from the main body 31. A guide plate 322 is arranged on at least one side in the width direction of the air outlet 321, and the guide plate 322 is arranged to extend obliquely from the side plate 32 toward the front side. The guide plate 322 can guide the airflow blown out of the air outlet 321. By setting the guide plate 322, the airflow direction of the air outlet 321 can be made to flow closer to the front side of the main body 31. In other words, the guide plate 322 can cooperate with the air outlet 321 to change the direction of the airflow to improve the uniformity of the airflow inside the cooking cavity 101.

[0038] Furthermore, the rotation direction of the air outlet blade has a tangential direction 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 plate 322 is at least arranged on the second side in the tangential direction. In this way, the guide plate 322 can be arranged to match the rotation direction of the air outlet blade, thereby effectively guiding the airflow to the cooking cavity 101.

[0039] It should be noted that the direction of the airflow generated by the rotation of the air outlet blades is not perpendicular to the extension direction of the side plate 32. And the direction of the airflow generated by the air outlet blades is related to the rotation direction of the air outlet blades. Figures 3 to 7 The case where the guide plate 322 is only provided on one side of the air outlet 321 can be referred to the following description.

[0040] refer to Figure 3 , when the air outlet blade rotates counterclockwise, for the side plate 32 on the left, the airflow direction is to the lower left. The rotation direction of the air outlet blade is downward in the tangential direction close to the side plate 32. The guide plate 322 needs to be arranged 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 upper side of the air outlet 321 is the first side, and the lower side of the air outlet 321 is the second side.

[0041] Combination Figure 3 , when the air outlet blade rotates counterclockwise, for the right side plate 32, the airflow direction is to the upper right. The rotation direction of the air outlet blade is upward in the tangential direction close to the side plate 32. The guide plate 322 needs to be arranged 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 lower side of the air outlet 321 is the first side, and the upper side of the air outlet 321 is the second side.

[0042] Combination Figure 4 For example, when the air outlet blades corresponding to the left return air outlet 311 rotate clockwise, and the air outlet blades corresponding to the right return air outlet 311 rotate counterclockwise, the airflow direction is to the upper left for the left side panel 32, and the airflow direction is to the upper right for the right side panel 32. Therefore, the rotation direction of the air outlet blades is upward in the tangent direction close to the side panels 32 on both sides. That is, for the side panels 32 on both sides, the lower side of the air outlet 321 is the first side, and the upper side of the air outlet 321 is the second side in the upward tangent direction.

[0043] Combination Figure 6For example, when the air outlet blades corresponding to the two return air outlets 311 rotate counterclockwise, similarly to the above, for the left side plate 32, the upper side of the air outlet 321 is the first side, and the lower side of the air outlet 321 is the second side. For the right side plate 32, the lower side of the air outlet 321 is the first side, and the upper side of the air outlet 321 is the second side.

[0044] The cooking device 1 may include only one air outlet blade, and the air outlet cover 30 is provided with a return air port 311. The air outlet blade is provided corresponding to the return air port 311. Side panels 32 are provided on both sides in the first reference direction, and air outlets 321 are provided on the side panels 32. In this case, the two sides of an air outlet blade correspond to one side panel 32. Since the tangent directions on both sides of an air outlet blade are opposite, the guide plate 322 on one of the side panels 32 is provided on one of the upper sides in the width direction of the air outlet 321, and the guide plate 322 on the other side panel 32 is provided on the other 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.

[0045] Combination Figure 4 , the cooking device 1 may include two air outlet blades. The main body 31 includes two return air ports 311, and the two air outlet blades are arranged corresponding to the two return air ports 311. Side panels 32 are respectively arranged on both sides in the first reference direction, and air outlets 321 are opened on the side panels 32. In this case, the rotation directions of the two air outlet blades can be selected to be opposite (one is counterclockwise and the other is clockwise), so that the air outlet blades are oriented in the same direction in the tangent direction of the side panels 32 respectively close to the two sides, and the guide plates 322 on the two side panels 32 are both arranged on the same side in the width direction of the air outlet 321 (same upper side or same lower side).

[0046] Combination Figure 6 , the rotation directions of the two air outlet blades can also be selected to be the same (both clockwise or counterclockwise). In this way, the tangent directions of the air outlet blades close to the two sides of the side plate body 32 are opposite. Therefore, the guide plate 322 on one of the side plates 32 is set on one side of the upper width direction of the air outlet 321, and the guide plate 322 on the other side plate body 32 is set on the other side of the lower width direction of the air outlet 321.

[0047] In some embodiments, in combination Figures 9 to 11 , guide plates 322 are provided on both sides of the air outlet 321 in the width direction.

[0048] In some embodiments, an auxiliary plate 33 is provided on at least one side of the second reference direction, and an auxiliary air outlet 331 is provided on the auxiliary plate 33. The auxiliary air outlet 331 can discharge a part of the airflow generated by the air outlet blades into the cooking cavity 101. Since the auxiliary plate 33 and the side plate 32 are in different directions, the airflow generated by the air outlet blades can be fully utilized in the above manner. By setting the area of ​​the auxiliary air outlet 331 to be smaller than the area of ​​the air outlet 321, the wind pressure of the air outlet 321 can be increased, so that most of the airflow is discharged from the air outlet 321, which is conducive to increasing the uniformity of the airflow through the setting of the side plate 32.

[0049] The above are merely embodiments of the present application and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
