Description

Technical Field

[0001] This application relates to the field of kitchen heating technology, and in particular to air vents and cooking equipment. Background Technology

[0002] In daily life, people frequently use cooking appliances such as steam ovens, ovens, or microwave ovens to cook food. These appliances require hot air components to blow out hot air and heat the food evenly. In related technologies, to accommodate various components and reduce the size of the appliance, a recessed structure is often incorporated into the side of the appliance. However, this recessed structure obstructs the flow of gas within the cooking cavity, reducing the uniformity of airflow. Utility Model Content

[0003] Embodiments of this application provide an air vent and a cooking device that can improve the uniformity of airflow distribution within the cooking cavity.

[0004] In a first aspect, embodiments of this application provide an air outlet shroud. The air outlet shroud includes a main body and a side plate. The main body is provided with a return air vent. The side plate is disposed on at least one side of the main body and is connected to the main body; wherein, the side plate is provided with an air outlet having a length direction and a width direction, and a guide plate is provided on at least one side of the side plate in the width direction of the air outlet, the guide plate being protruding relative to the side plate.

[0005] Optionally, the motherboard body has different first reference directions and second reference directions. The motherboard body has a side plate on at least one side in the first reference direction, and the length direction of the air outlet is set at an angle with the first reference direction.

[0006] Optionally, the first reference direction is the length direction of the motherboard body, and the second reference direction is the width direction of the motherboard body;

[0007] And / or, when the air vent is in use, the second reference direction is the direction of gravity. In the direction away from the motherboard, the end of the air vent closer to the motherboard is closer to the upper part of the direction of gravity than the end of the air vent further away from the motherboard.

[0008] Optionally, the main body has a front side and a rear side in its thickness direction, and in the direction away from the main body, the side plate is inclined to the rear side from the outer edge of the main body, and the guide plate is inclined to the front side from the side plate.

[0009] Optionally, the air deflector is located on the side of the air outlet closer to the main body in the width direction;

[0010] And / or, the air deflector is located on the side of the air outlet away from the main body in the width direction.

[0011] Optionally, guide vanes are provided on both sides of the air outlet width direction, and the guide vanes on both sides extend at an angle from the side plate toward each other.

[0012] 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.

[0013] Optionally, the main body of the equipment has openings at both ends, an air hood is installed at one of the opening ends of the main body of the equipment, a recessed part is provided on one side of the main body of the equipment, and a side plate is provided on the side adjacent to the side of the main body and the recessed part.

[0014] Optionally, the cooking device also includes two air outlet blades, and the main body includes two return air vents, with the two air outlet blades corresponding to the two return air vents;

[0015] Alternatively, the cooking device may include an air outlet blade, which is configured to correspond to the air return vent.

[0016] Optionally, the rotation direction of the air outlet blades is tangential near the side plate. In the tangential direction, the air outlet has a first side and a second side in sequence, and the guide plate is at least located on the second side in the tangential direction.

[0017] The beneficial effects of this application are as follows: Unlike existing technologies, the airflow generated by the air outlet AA port of the side panel can be guided into the cooking cavity by the air outlet blades of the cooking equipment, and the airflow in the cooking cavity can be returned to the air outlet blades through the return air port of the main panel. This method creates an airflow circulation within the cooking cavity. Furthermore, by installing a guide vane at the air outlet, the airflow direction can be changed and corrected. Correcting the airflow direction with the guide vane deviates the airflow direction from at least one side of the main panel, thereby reducing the interference of downward movement on the corresponding side of the cooking equipment and increasing the uniformity of the airflow.

[0028] 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.

[0029] 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.

[0030] 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 main body 10 has openings at both ends that communicate with the cooking cavity 101. 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.

[0031] 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 by the cooking cavity 101, thereby reducing the overall space occupied by the cooking device 1.

[0032] Combination Figure 2 The air outlet assembly 20 is installed on the main body 10 of the device. 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 drive unit, and air outlet blades. The drive unit can be fixed to the fixed cover by 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.

[0033] 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.

[0034] In some embodiments, combined with Figure 2The 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.

[0035] In some embodiments, there are multiple air outlet hoods 30 and multiple air outlet assemblies 20. The air outlet hood 30 may include an air outlet hood 30 with a single return air inlet 311 or an air outlet hood 30 with multiple return air inlets 311. The air outlet hood 30 may also include air outlet hoods 30 with air outlets 321 of different shapes. The air outlet assembly 20 may include a single-fan assembly or a dual-fan assembly, etc. The device body 10 is a general-purpose 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 with different configurations. For example, during assembly, depending on the required configuration, a dual-fan air outlet assembly 20 and a dual-return air inlet 311 air outlet hood 30 can be installed on the device body 10; or a single-fan air outlet assembly 20 and a single return air inlet 311 air outlet hood 30 can be installed.

[0036] In related technologies, to make the cooking device 1 occupy less space, the size of its components needs to be reduced. The air outlet assembly 20 contains many components, and reducing its size can significantly reduce space occupation and improve space utilization. However, the air outlet assembly 20 needs to rotate to expel air, so how to reduce its size while ensuring normal operation is a technical problem that needs to be considered. To improve the above-mentioned technical problem, this application can provide the following embodiments.

[0037] In related technologies, 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 obstructs the airflow from the exhaust hood 30, resulting in a decrease in the uniformity of airflow within the cooking cavity 101. To improve the above-mentioned technical problems, this application can provide the following embodiments.

[0038] It should be noted that the embodiments provided in this application also achieve the technical effect of improving airflow uniformity without the sinking portion 11. This application has made a targeted design for the case with the sinking portion 11, and compared with the solutions in related technologies, the embodiments of this application have a better effect on improving airflow uniformity for the case with the sinking portion 11.

[0039] Reference Figure 3 , Figure 4 Figure 6 and Figure 8 As illustrated, 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 within the cooking cavity 101.

[0040] 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.

[0041] In this embodiment, the side plate 32 is disposed on the adjacent side of the main plate 31 and the recessed portion 11. 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.

[0042] This application embodiment provides an air outlet hood 30. An air outlet 321 disposed on a side panel 32 has a length direction and a width direction. A guide plate 322 is disposed on at least one side of the air outlet 321 in the width direction, and the guide plate 322 protrudes from the side panel 32. The guide plate 322 can guide the airflow blown from the air outlet 321. By providing the guide plate 322, the airflow from the air outlet 321 can be directed towards the front side of the main body 31. On the other hand, by providing the guide plate 322, it can cooperate with the deflection of the air outlet blades to guide the airflow away from the recessed portion 11, thereby reducing the obstruction of the airflow by the recessed portion 11. In other words, the guide plate 322 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.

[0043] In some embodiments, the air outlet 321 is inclined relative to the first reference direction along its length. In other words, the length direction of the air outlet 321 forms an angle with the first reference direction. Due to the inclination of the air outlet 321, the airflow outlet position gradually moves away from one side of the motherboard 31 in the direction away from the motherboard 31, thereby reducing the influence of the corresponding components on the airflow. Optionally, the end of the air outlet 321 closer to the motherboard 31 is positioned closer to the upper direction of gravity than the end of the air outlet 321 farther from the motherboard 31.

[0044] In some embodiments, 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. A guide plate 322 extends inclined forward from the side plate 32. A guide plate 322 is provided on at least one side of the air outlet 321 in its width direction, extending inclined forward from the side plate 32. The guide plate 322 guides the airflow from the air outlet 321. By providing the guide plate 322, the airflow from the air outlet 321 can be directed towards the front of the main body 31. In other words, the guide plate 322, in conjunction with the air outlet 321, can change the direction of the airflow to improve the uniformity of the airflow inside the cooking cavity 101.

[0045] In some embodiments, combined with Figures 3 to 7 The air deflector 322 is located on the side of the air outlet 321 closer to the main body 31 in the width direction, or the air deflector 322 is located on the side of the air outlet 321 away from the main body 31 in the width direction.

[0046] Specifically, the placement of the deflector 322 on one side is related to the rotation direction of the air outlet blades. The rotation direction of the air outlet blades is tangential near the side plate 32. In this tangential direction, the air outlet 321 has a first side and a second side in sequence, and the deflector 322 is at least located on the second side in the tangential direction. In this way, the placement of the deflector 322 can be matched with the rotation direction of the air outlet blades, thereby effectively guiding the airflow to the cooking cavity 101.

[0047] 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. For example... 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.

[0048] 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.

[0049] Combination Figure 5 The 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. 。

[0050] Combination Figure 4The 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 be selected to be opposite (one counterclockwise and the other clockwise), so that the air outlet blades face the same direction in the tangential direction near the side plates 32 on both sides, and the guide plates 322 on the two side plates 32 are both arranged on the same side in the width direction of the air outlets 321 (both are located at the top or the same bottom).

[0051] The rotation direction of the two air outlet blades can also be the same (both clockwise or both counterclockwise). In this way, the tangential directions of the air outlet blades near the two sides of the side plate 32 are opposite. Therefore, the guide plate 322 on one side plate 32 is located on one of the upper sides of the air outlet 321 in the width direction, while the guide plate 322 on the other side plate 32 is located on the lower side of the air outlet 321 in the width direction.

[0052] In this embodiment, an auxiliary plate 33 is provided on at least one side in the second reference direction, and the auxiliary plate 33 has an auxiliary air outlet 331. The auxiliary air outlet 331 can discharge a portion 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 this 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 exits from the air outlet 321, which is beneficial to increasing the uniformity of airflow through the arrangement of the side plate 32.

[0053] Combination Figures 8 to 10 In other embodiments, guide vanes 322 are provided on both sides of the air outlet 321 in the width direction, and the guide vanes 322 on both sides extend obliquely from the side plate 32 towards each other. In this case, when the air outlet blades rotate clockwise, the airflow can be mainly guided by the guide vane 322 on one side in the width direction. When the air outlet blades rotate counterclockwise, the airflow can be mainly guided by the guide vane 322 on the other side in the width direction. In this way, the airflow can be guided to the front side by the guide vanes 322 on different sides, regardless of whether the air outlet blades rotate clockwise or counterclockwise. Optionally, the guide vanes 322 on different sides can have different guiding effects on the airflow. In the second reference direction, the guide vanes 322 on both sides can guide the airflow mainly to the upper and lower sides, respectively. In this way, the air outlet blades can also guide the airflow to the upper and lower sides by rotating clockwise and counterclockwise alternately, thereby effectively increasing the uniformity of the airflow.

[0054] The above are merely embodiments of this application and do not limit the patent scope of this application.
