[0060] Please refer to Figures 1 to 8As shown, the utility model provides a kind of upper cover assembly 100, upper cover assembly 100 includes cover body 1, cooling device 2 and flow guide piece 3, cover body 1 is equipped with temperature regulating cavity 13, heating element 4 is equipped in temperature regulating cavity 13, cooling device 2 is located in cover body 1, cooling device 2 is spaced apart from temperature regulating cavity 13, cooling device 2 is equipped with cooling air outlet 22, flow guide piece 3 is located in cover body 1, flow guide piece 3 is equipped with flow guide passage 32, flow guide passage 32 is communicated temperature regulating cavity 13 and cooling air outlet 22.

[0061] In the embodiment, the upper cover assembly 100 is applied to a cooking appliance 500, which includes but is not limited to an electric rice cooker, a pressure electric rice cooker, an electric soup pot, an electric medicine pot and an electric wok, and the upper cover assembly 100 is used to cover the main body (such as a pot body 501) of the cooking appliance 500. The upper cover assembly 100 includes a cover body 1, a cooling device 2 and a flow guide piece 3. The cover body 1 is a main support component of the upper cover assembly 100. The cover body 1 can be a shell structure or a plate structure, which is used to mount the cooling device 2 and the flow guide piece 3.

[0062] In the embodiment, the cooling device 2 is a device that generates a cold source fluid, such as a fan that can generate airflow, a gas pump or a water pump that can generate water flow, etc. In addition, the cover body 1 is provided with a temperature regulating cavity 13, and the cooling device 2 is provided with a cooling air inlet 21 and a cooling air outlet 22. The cooling air inlet 21 is used to obtain airflow from the outside, and the cooling air outlet 22 can be directly communicated with the temperature regulating cavity 13, so that the cold source fluid generated by the cooling device 2 can enter the temperature regulating cavity 13. Specifically, the temperature regulating cavity 13 is arranged on the cover body 1. The temperature regulating cavity 13 can be arranged in a tubular shape or in a cavity shape. When the temperature regulating cavity 13 is arranged in a tubular shape, it can have only one air inlet and one air outlet and be arranged in a zigzag form on the entire plane of the side of the cover body 1 that contacts the cooking cavity of the cooking appliance 500, or it can have multiple air inlets and multiple air outlets and be arranged in parallel on the entire plane of the side of the cover body 1 that contacts the cooking cavity of the cooking appliance 500. When the temperature regulating cavity 13 is arranged in a cavity shape, it is a complete large cavity arranged on the entire plane of the side of the cover body 1 that contacts the cooking cavity of the cooking appliance 500.

[0063] Further, the upper cover assembly 100 and the cooking appliance 500 with the upper cover assembly 100 have a cooling state. During the cooking process of the cooking appliance 500, water vapor carries away the aroma molecules of the rice, thereby reducing the aroma of the rice. By arranging the cooling device 2 and the temperature regulating cavity 13, the cooling device 2 blows cooling fluid into the temperature regulating cavity 13 during the boiling stage, so as to condense the water vapor containing the aroma molecules of the rice in the cooking cavity through the cover body 1, and make the water vapor condense on the cover body 1 and flow back into the cooking cavity, thereby improving the aroma of the rice.

[0064] Meanwhile, the upper cover assembly 100 further comprises a heating element 4 for generating heat for the upper cover assembly 100. During the cooking process, especially in the later stage of cooking, the temperature in the cooking cavity gradually decreases after the food is cooked, and water vapor will condense on the cover body 1 of the upper cover assembly 100. When the upper cover assembly 100 is opened, the condensed water will fall into the food, affecting the taste and hygiene safety of the food. Therefore, the cooking appliance 500 can control the heating element 4 on the upper cover (the upper cover assembly 100) to generate heat. At this time, the heating element 4 can conduct heat to the cover body 1. By controlling the operating power of the heating element 4, the temperature of the cover body 1 can be kept consistent with the temperature of the cooking cavity of the pot body, which can prevent the water vapor in the pot body from spreading to the cover body 1 to form condensed water, thereby avoiding the condensed water from falling into the cooking cavity when the upper cover assembly 100 is opened, so that the food after cooking can have a better taste.

[0065] The heating element 4 is arranged in the temperature adjusting cavity 13 of the cover body 1. The heating element 4 can be an electric heating wire structure, an electric heating film structure, or an infrared heating structure, etc. The heating element 4 is electrically connected to an external power source, so that the heating element 4 can heat the upper cover assembly 100 as a whole. For example, the heating element 4 is a heating film which is coated on or attached to a heat-conducting substrate made of a glass substrate. The heating element 4 can be made of graphene, metal, or other heating materials. The upper cover assembly 100 is provided with a heat-conducting substrate, and the heating element 4 is usually attached to the surface of the heat-conducting substrate. When the upper cover assembly 100 covers the cooking cavity of the cooking appliance 500, one side of the cover body 1 directly contacts the cooking cavity, and the heating element 4 is arranged on the side of the cover body 1 away from the cooking cavity, so as to heat the cover body 1 and keep the temperature of the cover body 1, thereby preventing water vapor from condensing on the cover body 1.

[0066] The temperature adjusting cavity 13 can cool the cover body 1 to obtain condensed water containing aroma molecules and heat the cover body 1 to reduce the influence of the condensed water on the food at different stages of cooking. However, the heating element 4 and the cooling device 2 are arranged at the same time, and the high-temperature environment of the temperature adjusting cavity 13 will inevitably affect the operating efficiency of the cooling device 2, and even the cooling device 2 may be damaged. Therefore, the upper cover assembly 100 further comprises a flow guide element 3 which can be a flow guide pipe, a flow guide cylinder, a flow guide plate, a flow guide wall, or the like.

[0067] In the embodiment, the flow guide element 3 is arranged in the temperature adjusting cavity 13 of the cover body 1. Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the flow guide 3 is arranged on the cover body 1, and the flow guide 3 is provided with a flow guide channel 32, which is in communication with the temperature adjusting cavity 13 and the cooling air outlet 22. Meanwhile, the cooling device 2 is arranged apart from the temperature adjusting cavity 13, so as to increase the distance between the cooling device 2 and the temperature adjusting cavity 13, and on the basis of reasonable layout of the structure of the cover body 1, the length of the flow guide channel 32 between the cooling device 2 and the temperature adjusting cavity 13 is prolonged, so as to prolong the fluid transmission path of the cooling device 2 and the temperature adjusting cavity 13, to reasonably arrange the position of the cooling device 2 relative to the temperature adjusting cavity 13, and the cooling device 2 is arranged apart from the temperature adjusting cavity 13, so as to avoid the cooling device 2 being too close to the temperature adjusting cavity 13 and being affected by the heating element 4 in the temperature adjusting cavity 13, especially after the temperature adjusting cavity 13 is heated, the cooling device 2 far away from the temperature adjusting cavity 13 can receive less heat emitted by the temperature adjusting cavity 13.

[0068] Meanwhile, the extension direction of at least part of the flow guide channel 32 is arranged in a changing manner from the cooling device 2 to the temperature adjusting cavity 13, so as to further increase the fluid transmission path of the flow guide channel 32, and reduce the influence of temperature change in the temperature adjusting cavity 13 on the cooling device 2, so as to protect the cooling device 2 and other electromechanical components.

[0069] The upper cover assembly 100 comprises the cover body 1, the cooling device 2 and the flow guide 3. The cover body 1 is provided with the temperature adjusting cavity 13. The cooling device 2 is arranged on the cover body 1, and the cooling device 2 is provided with the cooling air outlet 22. The flow guide 3 is arranged on the cover body 1, and the flow guide 3 is provided with the flow guide channel 32, which is in communication with the cooling air outlet 22 and the temperature adjusting cavity 13, so as to guide the airflow from the cooling air outlet 22 to the temperature adjusting cavity 13. The cooling device 2 is arranged on the upper part of the temperature adjusting cavity 13 along the thickness direction of the cover body 1, so as to prolong the length of the flow guide channel 32 between the cooling device 2 and the temperature adjusting cavity 13, thereby prolonging the fluid transmission path from the temperature adjusting cavity 13 to the cooling device 2. Meanwhile, the cooling device 2 is arranged apart from the temperature adjusting cavity 13, so as to reduce the influence of temperature change in the temperature adjusting cavity 13 on the cooling device 2, thereby protecting the cooling device 2 and other electromechanical components.

[0070] In an embodiment, the cooling device 2 is arranged apart from the temperature adjusting cavity 13 along the thickness direction of the cover body 1. Optionally, the cooling device 2 is located on the upper part of the temperature adjusting cavity 13 along the thickness direction of the cover body 1.

[0071] In the embodiment, the cover body 1 has a thickness direction, and the thickness direction of the cover body 1 is also the direction of natural upward flow of the hot steam. The cooling device 2 can be arranged apart from the temperature adjusting cavity 13 along the thickness direction of the cover body 1, and when the cooling device 2 is arranged apart from the temperature adjusting cavity 13 along the thickness direction or the planar direction of the cover body 1, the cooling device 2 can be located on the upper part of the temperature adjusting cavity 13 along the thickness direction of the cover body 1.

[0072] It can be understood that by arranging the cooling device 2 to be spaced apart from the temperature adjusting cavity 13 along the thickness direction of the cover body 1, the length of the flow channel 32 between the cooling device 2 and the temperature adjusting cavity 13 is extended, the fluid transmission path from the temperature adjusting cavity 13 to the cooling device 2 is extended, and the cooling device 2 is arranged to be spaced apart from the temperature adjusting cavity 13, so as to reduce the influence of temperature change in the temperature adjusting cavity 13 on the cooling device 2, thereby protecting the cooling device 2 and other electromechanical components.

[0073] In an embodiment, as shown in Figure 1 and Figure 2 , the cooling device 2 is arranged to be spaced apart from the temperature adjusting cavity 13 along the planar direction of the cover body 1; it can be understood that the planar direction of the cover body 1 is perpendicular to the thickness direction of the cover body 1, that is, the plane direction of the cover body 1 is the plane direction of the cavity opening of the cooking cavity. The cooling device 2 can be arranged to be spaced apart from the temperature adjusting cavity 13 only along the planar direction of the cover body 1, and the cooling device 2 can be arranged to be spaced apart from the temperature adjusting cavity 13 along the thickness direction and the planar direction of the cover body 1 at the same time, such as being arranged at the edge of the temperature adjusting cavity 13 and being arranged above or below the cover body 1 along the thickness direction, so as to extend the length of the flow channel 32 between the cooling device 2 and the temperature adjusting cavity 13, thereby extending the fluid transmission path from the temperature adjusting cavity 13 to the cooling device 2, and arranging the cooling device 2 to be spaced apart from the temperature adjusting cavity 13, so as to reduce the influence of temperature rise in the temperature adjusting cavity 13 on the cooling device 2, thereby protecting the cooling device 2 and other electromechanical components.

[0074] Optionally, the cooling device 2 is a fan, and the distance between the rotating shaft of the fan and the outer edge of the nearest temperature adjusting cavity 13 is greater than or equal to 1 mm and less than or equal to 40 mm; it can be understood that the cooling device 2 is a fan structure, the fan has a rotating shaft, and the distance between the rotating shaft of the fan and the outer edge of the nearest temperature adjusting cavity 13 is greater than or equal to 1 mm and less than or equal to 40 mm, so as to ensure that the cooling device 2, that is, the fan, has a proper distance from the temperature adjusting cavity 13 in the planar direction, and on the basis of ensuring the reasonable layout of the overall cover assembly 100, the cooling device 2 and the temperature adjusting cavity 13 have a certain distance therebetween, so as to reduce the influence of temperature rise in the temperature adjusting cavity 13 on the cooling device 2.

[0075] In an embodiment, as shown in Figure 1 and Figure 2 , the cooling device 2 is arranged at the edge of the temperature adjusting cavity 13.

[0076] In the embodiment, the cooling device 2 is arranged on the cover body 1 and at the edge of the temperature adjusting cavity 13; the cooling device 2 can be arranged at the outer edge of the upper surface of the temperature adjusting cavity 13 or at the outer edge of the side wall, and the cooling device 2 can be arranged to be spaced apart from the temperature adjusting cavity 13, so as to make the cooling device 2 as far away from the temperature adjusting cavity 13 as possible or to keep a certain distance from the cooling device 2.

[0077] It can be understood that, since the heating element 4 is arranged in the temperature adjusting cavity 13, the cooling device 2 will inevitably be affected during the heating of the heating element 4. For example, when the cooling device 2 is a fan, the heat generated by the heating element 4 will cause the temperature of the fan to rise, thereby reducing the output efficiency of the fan and affecting the normal cooling and condensation. Therefore, the cooling device 2 is arranged at the edge of the temperature adjusting cavity 13, so that the cooling device 2 is away from the heating element 4 arranged in the temperature adjusting cavity 13. In addition, by arranging the flow guide channel 32, the cooling device 2 can also input airflow into the temperature adjusting cavity 13 during condensation, thereby effectively reducing the influence of the heating element 4 on the cooling device 2, reducing the heat diffused from the temperature adjusting cavity 13 to the cooling device 2, reducing the working temperature of the cooling device 2, and ensuring the working life of the cooling device 2.

[0078] Based on the arrangement of the flow guide channel 32 by the flow guide element 3, the position of the cooling device 2 relative to the temperature adjusting cavity 13 on the cover body 1 of the upper cover assembly 100 can be reasonably arranged. For example, the cooling device 2 is arranged at the edge of the temperature adjusting cavity 13, which effectively improves the compactness of the structure of the upper cover assembly 100. At the same time, the cooling device 2 located at the edge of the temperature adjusting cavity 13 can also input cooling fluid into the temperature adjusting cavity 13 through the flow guide channel 32, while reducing the negative influence of the heating in the temperature adjusting cavity 13 on the cooling device 2.

[0079] In an embodiment, as shown in Figures 1 to 7 The cover body 1 includes an inner cover 11 and a seat plate 12, and the inner cover 11 and the seat plate 12 enclose the temperature adjusting cavity 13. The inner cover 11 is located at the upper part of the seat plate 12 along the thickness direction of the cover body 1. The cooling device 2 is arranged on the side of the inner cover 11 away from the seat plate 12.

[0080] In this embodiment, the cover body 1 is arranged on the pot body 501 of the cooking utensil 500, and the cover body 1 and the pot body 501 are the main structures of the cooking utensil 500. The cover body 1 includes an inner cover 11 and a seat plate 12. The seat plate 12 is arranged on the pot body 501 of the cooking utensil 500. When the cover body 1 covers the pot body 501, the seat plate 12 and the pot body 501 of the cooking utensil 500 enclose a cooking cavity for cooking food. When the rice boils, the cooling device 2 blows cooling airflow into the temperature adjusting cavity 13 through the flow guide channel 32 to cool the seat plate 12, and cools the steam containing aroma substances in the cooking cavity through the seat plate 12, so that the steam condenses and flows back to the cooking cavity to continue participating in the cooking of the rice, thereby solving the problem of loss of aroma substances caused by violent boiling.

[0081] Further, the inner cover 11 is connected to the side of the seat plate 12 away from the pot body 501, the inner cover 11 is snap-fit connected to the seat plate 12, and the inner cover 11 and the seat plate 12 are spaced apart to enclose a space in the middle to form a temperature regulating cavity 13, and the cooling device 2 is arranged on the side of the inner cover 11 away from the seat plate 12, and the flow guide channel 32 can also be arranged on the side of the inner cover 11 away from the seat plate 12, and the cooling airflow is blown into the temperature regulating cavity 13 from the side of the inner cover 11 away from the seat plate 12 to cool the seat plate 12.

[0082] It can be understood that the cooling device 2 is arranged on the side of the inner cover 11 away from the seat plate 12, so that the cooling device 2, the inner cover 11 and the seat plate 12 can be arranged in sequence along the thickness direction of the upper cover assembly 100, effectively reducing the space occupied by the cooling device 2 in the circumferential direction of the cover body 1 of the upper cover assembly 100, improving the compactness of the structure of the cover body 1, and the cooling device 2 can also be arranged at the edge of the inner cover 11, thereby being away from the heating element 4 in the temperature regulating cavity 13, reducing the heat transfer of the heating element 4 to the cooling device 2, reducing the working temperature of the cooling device 2, and ensuring the working life of the cooling device 2.

[0083] At the same time, the cooling device 2 is arranged on the inner cover 11, which is convenient for arranging the flow guide channel 32 on the side of the inner cover 11 away from the seat plate 12, so that the airflow generated by the cooling device 2 can be blown into the temperature regulating cavity 13 from the upper part of the temperature regulating cavity 13 through the flow guide channel 32, so that the cooling airflow can be diffused to the whole temperature regulating cavity 13, and the temperature regulating cavity 13 is arranged in the whole along the plate body extension direction of the seat plate 12, which further improves the uniformity of the airflow flowing in the temperature regulating cavity 13, improves the uniformity and cooling efficiency of the whole cooling.

[0084] Further, when the cooling fluid in the flow guide channel 32 is input into the temperature regulating cavity 13, the cooling fluid in the flow guide channel 32 can enter from the upper part of the temperature regulating cavity 13 (i.e. the side of the inner cover 11), and the cold air with lower temperature can flow from the upper part to the lower part of the temperature regulating cavity 13 (i.e. from the inner cover 11 to the seat plate 12), and the lower part of the temperature regulating cavity 13 is the seat plate 12, and the side of the seat plate 12 away from the inner cover 11 after being in contact with the hot steam in the cooking cavity, the temperature of the fluid on the seat plate 12 in the temperature regulating cavity 13 rises, and the hot air has higher temperature, so after being heated, the volume expands, the density becomes smaller, and the weight becomes lighter, so that the air with higher temperature flows to the upper part of the temperature regulating cavity 13 (i.e. from the seat plate 12 to the inner cover 11), and flows out from the air outlet of the temperature regulating cavity 13, to form a heat cycle in the temperature regulating cavity 13, and the air with lower temperature entering from the upper part of the first communication hole a constantly flows from the inner cover 11 to the seat plate 12 to cool the seat plate 12, and condenses the water vapor on one side of the cooking cavity through the seat plate 12, effectively improving the condensation effect of the seat plate 12 on the cooking cavity.

[0086] It can be understood that the flow guide channels 32 communicate the temperature adjusting cavity 13 and the cooling air outlet 22 of the cooling device 2, wherein part of the flow guide channels 32 extend into the temperature adjusting cavity 13, and the extending direction of the flow guide channels 32 located in the temperature adjusting cavity 13 is arranged at an angle to the extending direction of the body of the inner cover 11, so that the cooling airflow in the flow guide channels 32 entering from the cooling device 2 can blow into the temperature adjusting cavity 13 in a direction that is at an angle to the extending direction of the body of the inner cover 11 and blow towards the seat plate 12, so that the airflow entering the temperature adjusting cavity 13 is more gentle and uniform, and will not be concentrated at the position of the seat plate 12 directly opposite the flow guide channels 32, ensuring the uniformity of the cooling of the seat plate 12 and improving the condensation effect of the steam containing the aroma substance.

[0087] At the same time, the inclined arrangement of the flow guide channels 32 can also increase the length of the flow guide channels 32, which is more convenient for adjusting the position of the cooling device 2 relative to the temperature adjusting cavity 13 and reducing the influence of the heating element 4 on the cooling device 2.

[0088] Optionally, the shortest distance between the inner cover 11 and the seat plate 12 is greater than or equal to 5 mm and less than or equal to 40 mm. It can be understood that the height of the temperature adjusting cavity 13 exceeding a certain range will make the capacity of the temperature adjusting cavity 13 too large, exceeding the flow load of the cooling device 2, reducing the heat exchange efficiency of the temperature adjusting cavity 13, and affecting the space of the cover body 1; limiting the distance between the inner cover 11 and the seat plate 12 is used to limit the height of the temperature adjusting cavity 13, and a sufficient height of the temperature adjusting cavity 13 can ensure the flow effect of the fluid in the temperature adjusting cavity 13, avoiding excessive wind resistance to weaken the cooling effect of the fluid.

Specifically, the top of the protruding portion 121 is provided with a pointed portion, so that the cross-sectional area of the protruding portion 121 along the extension direction is gradually reduced, for example, the top of the protruding portion 121 is a polygonal conical structure, which is beneficial to the condensate water gathering at the top of the protruding portion 121 and dripping back to the food being cooked, thereby reducing the evaporation loss of food aroma. In other embodiments, the top of the protruding portion 121 can also be cylindrical or prismatic or curved.

The surface of the deflector 31 can be a plane or a curved surface, so that the flow guide channel 32 formed by the deflector 31 can be a straight channel or a winding channel. Preferably, the flow guide channel 32 is arranged as a winding channel to reduce the diffusion of the heating element 4 in the temperature adjusting cavity 13 to the cooling device 2 directly through the flow guide channel 32, thereby effectively reducing the working temperature of the cooling device 2 and ensuring the service life of the cooling device 2.
