[0048] The present application will be described below in conjunction with the accompanying drawings and specific embodiments:

[0049] The cover and the electric appliance provided by the embodiment can at least solve the problem of excessive steam output and easy scalding of users to some extent.

[0050] Figure 1 The structure diagram of the cover of some embodiments; Figure 2 The cover is Figure 1 The steam flow diagram of the cover; Figure 3 The cover is Figure 2 The top view of the cover; Figure 4 The cover is Figure 1 The cross-sectional view of the cover. In combination with Figure 1 , Figure 2 , Figure 3 and Figure 4 , the cover of the embodiment of the present application comprises a shell 10 and an airflow channel 30. The shell 10 is provided with an inlet hole 101 and an outlet hole 102. The airflow channel 30 communicates the inlet hole 101 and the outlet hole 102, and the airflow channel 30 comprises a plurality of airflow sections 301. In the steam discharge direction, the bottom height of at least one airflow section 301 gradually decreases.

[0051] One of the inlet hole 101 and the outlet hole 102 communicates with one of the plurality of airflow sections 301, and the other communicates with one of the remaining airflow sections 301.

[0052] Due to the fact that the shell 10 is provided with the steam inlet hole 101 and the steam outlet hole 102, and the airflow channel 30 is communicated with the steam inlet hole 101 and the steam outlet hole 102, the steam can enter the airflow channel 30 through the steam inlet hole 101, the flow path of the steam can be extended through the airflow channel 30, the steam can be fully condensed in the airflow channel 30, part of the steam can be condensed into water droplets, the amount of steam discharged can be reduced, the temperature of another part of the steam can be reduced, and then the amount of steam sprayed from the steam outlet hole 102 can be reduced and the temperature of the steam can be reduced, the safety hazard of steam scalding can be effectively eliminated, and the user experience can be improved. Due to the fact that the airflow channel 30 includes a plurality of airflow sections 301, and the height of the bottom of at least one airflow section 301 gradually decreases along the steam discharge direction, the steam discharge path can be further extended, the steam discharge time can be extended, and the steam can be fully condensed in the airflow section 301.

[0053] In some embodiments, the steam inlet hole 101 can be located at the middle position of the shell 10, and of course, in other embodiments, the steam inlet hole 101 can also be located at a non-middle position of the shell 10.

[0054] In some embodiments, the steam outlet hole 102 can be directly communicated with the outside, or can be communicated with the heating chamber of the electric appliance, or can be communicated between the heating chamber of the electric appliance and the shell of the electric appliance.

[0055] In some embodiments, when the steam outlet hole 102 is communicated with the heating chamber of the electric appliance, when the air pressure in the heating chamber of the electric appliance increases, the pressure relief component of the electric appliance can be relieved to ensure the safety of the heating chamber of the electric appliance.

[0056] In some embodiments, when the steam outlet hole 102 is communicated between the heating chamber of the electric appliance and the shell of the electric appliance, the temperature controller can be triggered to detect the temperature of the steam, and when the temperature reaches the set requirement, the controller of the electric appliance can control the heating component of the electric appliance to reduce the heating power and perform heat preservation.

[0057] In some embodiments, in order to increase the resistance of steam flow, facilitate the condensate to flow into the heating chamber of the electrical appliance through the steam inlet hole, the bottom height of at least one airflow section 301 gradually increases, so that the speed of steam flow is slowed down, the time of steam staying in the airflow section 301 with gradually increasing bottom height is increased, so as to facilitate the condensation of steam into water droplets, and at the same time, under the action of gravity, the condensed water droplets of steam flow along the airflow section 301 to the direction of the steam inlet hole 101 and then flow into the heating chamber of the electrical appliance, avoiding too much condensed water droplets in the shell 10 and avoiding the leakage of condensed water droplets, further improving the user experience, reducing the waste of water resources, increasing the resistance of steam flow, reducing the speed of steam flow, and prolonging the time of steam in the airflow section 301 to enable steam to have sufficient time to condense.

[0058] In some embodiments, in order to further increase the resistance of steam flow, the number of airflow sections 301 with gradually increasing bottom height is greater than the number of airflow sections 301 with gradually decreasing bottom height, so that the speed of steam flow is slowed down by the airflow section 301 with gradually increasing bottom height, and the time of steam staying in the airflow section 301 with gradually increasing bottom height is increased, so as to facilitate the condensation of steam into water droplets. The number of airflow sections 301 with gradually increasing bottom height can be one more than the number of airflow sections 301 with gradually decreasing bottom height.

[0059] In some embodiments, the bottom height of at least one airflow section 301 gradually decreases and the bottom height of at least one airflow section 301 gradually increases, which realizes the staggered arrangement of high and low, increases the resistance of steam flow, reduces the speed of steam flow, prolongs the time of steam in the airflow section 301, enables steam to have sufficient time to condense in the airflow section 301, so that part of the steam condenses into water droplets, reduces the amount of steam discharged, and at the same time, another part of the steam has sufficient time to cool down in the airflow section 301, which can reduce the temperature of another part of the steam, thereby reducing the amount of steam sprayed from the steam outlet hole 102 and reducing the temperature of the steam, effectively eliminating the safety hazard of steam scalding, and improving the user experience.

[0060] In some embodiments, in order to ensure the residence time of steam in the airflow passage 30, the steam inlet hole 101 and the steam outlet hole 102 are respectively located at both ends of the airflow passage 30, steam enters the airflow passage 30 through the steam inlet hole 101 and then is discharged from the steam outlet hole 102, which can enable steam to be fully condensed in the airflow passage 30 to reduce the amount of steam discharged.

[0061] In some embodiments, in order to avoid direct discharge of steam, the steam inlet hole 101 and the steam outlet hole 102 are misaligned, that is, the steam inlet hole 101 and the steam outlet hole 102 are not coaxial, and the steam entering the airflow channel 30 through the steam inlet hole 101 will not be directly discharged by the steam outlet hole 102, ensuring the residence time of the steam in the airflow channel 30.

[0062] In some embodiments, in order to facilitate the flow of condensed water in the airflow section 301 into the steam inlet hole 101, the steam inlet hole 101 is lower than the lowest part of the airflow section 301. Under the action of gravity, the water droplets condensed from the steam will flow along the airflow section 301 towards the steam inlet hole 101 and flow into the heating chamber of the electric appliance, avoiding excessive condensation of water droplets in the shell 10.

[0063] In some embodiments, in order to facilitate the discharge of steam, the steam outlet hole 102 is higher than the highest part of the airflow section 301, while avoiding the discharge of condensed water from the steam outlet hole 102, avoiding the leakage of condensed water, and further improving the user experience.

[0064] In some embodiments, in order to form the airflow section 301, a plurality of surrounding shells 20 are arranged in the shell 10 and located between the steam inlet hole 101 and the steam outlet hole 102. Each two adjacent surrounding shells 20 and the shell 10 and the adjacent surrounding shells 20 form an airflow section 301 respectively. The two airflow sections 301 on both sides of the same surrounding shell 20 are communicated, and the steam inlet hole 101 and the steam outlet hole 102 are respectively communicated with different airflow sections 301. Therefore, the steam can enter the airflow section 301 through the steam inlet hole 101, the steam flow path can be increased through the plurality of airflow sections 301, the steam discharge path can be prolonged, the steam can be fully condensed in the airflow section 301, part of the steam is condensed into water droplets, the amount of steam discharged is reduced, the temperature of another part of the steam is reduced, and the amount of steam sprayed from the steam outlet hole 102 is reduced, the steam temperature is reduced, the safety hazard of steam scalding is effectively eliminated, and the user experience is improved.

[0065] In some embodiments, in order to avoid the accumulation of water in the airflow section 301 with gradually decreasing bottom height, the surrounding shell 20 is arranged with a gap from the bottom of the shell 10, that is, there is a gap between the surrounding shell 20 and the bottom of the shell 10, so that the condensed water in the airflow section 301 with gradually decreasing bottom height can flow into the steam inlet hole 101 through the gap. Under the action of gravity, the water droplets condensed from the steam will flow towards the steam inlet hole 101 and flow into the heating chamber of the electric appliance, avoiding excessive condensation of water droplets in the shell 10, avoiding leakage of condensed water, further improving the user experience, reducing the waste of water resources, increasing the resistance of steam flow, reducing the steam flow speed, prolonging the time of steam in the airflow section 301, and allowing the steam to have sufficient time to condense in the airflow section 301.

[0066] In some embodiments, if the food is heated, the flow path of the steam is lifted by the airflow section 301, which can guide the condensation of the steam, maximize the retention of food nutrients, and reduce the taste pollution caused by steam emission.

[0067] In combination with Figure 1 , Figure 2 and Figure 3 , in some embodiments, in order to further extend the steam exhaust path, two airflow sections 301 on both sides of the same enclosure 20 are concentrically arranged. Among them, the cross-sectional shape of the enclosure 20 can be arc-shaped.

[0068] In some embodiments, since the cross-sectional shape of most of the shell 10 is circular, two airflow sections 301 on both sides of the same enclosure 20 are concentrically arranged, which can be adapted to the shell 10, so as to facilitate the assembly of the enclosure 20.

[0069] In combination with Figure 1 , Figure 2 and Figure 3 , in some embodiments, in order to further extend the steam exhaust path, a plurality of enclosures 20 are sequentially and spaced apart from the middle of the shell 10 to the edge of the shell 10, the airflow section 301 is formed between two adjacent enclosures 20 and between the outermost enclosure 20 of the plurality of enclosures 20 and the inner wall of the shell 10, the airflow section 301 on both sides of the same enclosure 20 is connected, one of the innermost airflow section 3011 and the outermost airflow section 3012 is communicated with the steam inlet hole 101, and the other is communicated with the steam exhaust hole 102.

[0070] In some embodiments, when the number of airflow sections 301 is three, the bottom height of the innermost airflow section 3011 gradually increases along the steam exhaust direction, the bottom height of the outermost airflow section 3012 gradually increases, and the bottom height of the airflow section between the innermost airflow section 3011 and the outermost airflow section 3012 gradually decreases.

[0071] In some embodiments, steam can enter one of the innermost airflow section 3011 and the outermost airflow section 3012 through the steam inlet hole 101, then enter the remaining airflow sections in the plurality of airflow sections 301, and finally, be exhausted from the other of the innermost airflow section 3011 and the outermost airflow section 3012, which can sufficiently increase the flow path of the steam, sufficiently extend the steam exhaust path, and fully condense the steam in the airflow section 301, so that part of the steam is condensed into water droplets, reducing the amount of steam discharged, while reducing the temperature of another part of the steam, thereby reducing the amount of steam sprayed from the steam exhaust hole 102 and the steam temperature, effectively eliminating the safety hazard of steam scalding, and improving the user experience.

[0072] In some embodiments, the innermost air flow section 3011 can be in communication with the steam inlet hole 101, and the outermost air flow section 3012 can be in communication with the steam outlet hole 102. Of course, in other embodiments, the outermost air flow section 3012 can be in communication with the steam inlet hole 101, and the innermost air flow section 3011 can be in communication with the steam outlet hole 102.

[0073] In combination with Figure 1 , Figure 2 and Figure 3 , in some embodiments, in order to further extend the steam outlet path, when the innermost air flow section 3011 can be in communication with the steam inlet hole 101, and the outermost air flow section 3012 can be in communication with the steam outlet hole 102, the head of the innermost air flow section 3011 is in communication with the steam inlet hole 101, the tail of the innermost air flow section 3011 is in communication with the head of the air flow channel adjacent to the innermost air flow section 3011, the air flow channels between the innermost air flow section 3011 and the outermost air flow section 3012 are sequentially connected in a head-to-tail manner, the head of the outermost air flow section 3012 is in communication with the tail of the air flow channel adjacent to the outermost air flow section 3012, and the tail of the outermost air flow section 3012 is in communication with the steam outlet hole 102, so that the steam can flow through each air flow section 301 sufficiently, the flow path of the steam can be sufficiently increased, the steam can be sufficiently condensed in the air flow section 301, part of the steam can be condensed into water droplets, the amount of steam discharged can be reduced, and the temperature of another part of the steam can be reduced, thereby reducing the amount of steam sprayed from the steam outlet hole 102 and the temperature of the steam, effectively eliminating the safety hazard of steam scalding, and improving the user experience.

[0074] In combination with Figure 1 , Figure 2 and Figure 3 , in some embodiments, in order to increase the space for containing condensed water, the outermost two surrounding shells 20 of the plurality of surrounding shells 20 are connected by the connecting piece 90, the spacing between the connecting piece 90 and the inner wall of the shell 10 is greater than the spacing between the outermost surrounding shell 20 and the shell 10, so that the containing cavity 40 is formed between the connecting piece 90 and the shell 10, the containing cavity 40 is in communication with the steam outlet hole 102, and when the steam is condensed into water droplets, the water droplets can be sufficiently contained through the containing cavity 40 to avoid the water droplets from being discharged from the steam outlet hole 102 and leaking, and further improve the user experience.

[0075] In some embodiments, when the accommodation cavity 40 communicates with the steam exhaust hole 102, the connecting piece 90 is recessed in the direction of the steam inlet hole 101, so that the connecting piece 90 is staggered with the steam exhaust hole 102, so that the accommodation cavity 40 can fully accommodate the water droplets condensed by the steam, at the same time, the lower cover 80 of the electric appliance is reversibly arranged on the main body of the electric appliance, and the steam exhaust hole 102 is closer to the turning position of the lower cover 80 than the steam inlet hole 101, that is, when the lower cover 80 is opened, the steam exhaust hole 102 is located below the steam inlet hole 101. Under the action of gravity, the water droplets in the airflow channel 30 will gather at the steam exhaust hole 102, and the accommodation cavity 40 can fully accommodate the gathered water droplets to avoid the water droplets from being discharged through the steam exhaust hole 102 due to excessive accumulation, to avoid water leakage, and to further improve the user's experience.

[0076] In some embodiments, the steam enters the accommodation cavity 40 through the airflow channel 30, and the accommodation cavity 40 can further increase the flow path of the steam, prolong the steam exhaust path, and condense the steam in the accommodation cavity 40, so that part of the steam condenses into water droplets, reduces the amount of steam discharged, and at the same time, reduces the temperature of another part of the steam, thereby reducing the amount of steam sprayed from the steam exhaust hole 102 and the steam temperature, effectively eliminating the safety hazard of steam scalding, and improving the user's experience.

[0077] In some embodiments, in order to further increase the flow path of the steam, the number of airflow channels 30 is two, and the two airflow channels 30 are symmetrically arranged, so that the steam flows in the two airflow channels 30, prolongs the steam exhaust path, and condenses the steam in the two airflow channels 30, so that part of the steam condenses into water droplets, reduces the amount of steam discharged, and at the same time, allows another part of the steam to have sufficient time to cool in the two airflow channels 30, which can reduce the temperature of another part of the steam, thereby reducing the amount of steam sprayed from the steam exhaust hole 102 and the steam temperature, effectively eliminating the safety hazard of steam scalding, and improving the user's experience.

[0078] In some embodiments, in order to ensure that the steam can flow into the two airflow channels 30 from the steam inlet hole 101, the airflow sections 301 corresponding to the two airflow channels 30 are connected and form a ring structure to ensure smooth steam flow and avoid steam leakage.

[0079] In some embodiments, in order to condense the steam in the airflow channel 30, a plurality of airflow sections 301 are arranged in sequence between the steam inlet hole 101 and the steam exhaust hole 102, wherein the cross-sectional area of the plurality of airflow sections 301 gradually decreases in the steam exhaust direction. When the steam flows into the plurality of airflow sections 301, the steam pressure in the plurality of airflow sections 301 can be changed to facilitate the condensation of the steam in the airflow channel 30 to form water droplets, thereby ensuring the condensation effect.

[0080] In some embodiments, the cross-sectional area of the same airflow section 301 can gradually decrease along the steam exhaust direction. Of course, in other embodiments, the cross-sectional area of the same airflow section 301 is the same, and the cross-sectional area of every two adjacent airflow sections 301 can gradually decrease along the steam exhaust direction.

[0081] In combination Figure 2 and Figure 3 In some embodiments, in order to increase the resistance of steam flow, the cover body further comprises a baffle plate 50. The baffle plate 50 is arranged on the shell 10 and located in the airflow section 301 communicating with the steam inlet hole 101. The baffle plate 50 is opposite to the steam inlet hole 101, that is, the steam entering the airflow section 301 from the steam inlet hole 101 will impact the baffle plate 50. By blocking the steam through the baffle plate 50, the resistance of steam flow is increased, the steam flow speed is reduced, the time of steam in the airflow section 301 is prolonged, so that the steam has sufficient time to condense in the airflow section 301, part of the steam is condensed into water droplets, the amount of steam exhausted is reduced, at the same time, another part of the steam has sufficient time to cool down in the airflow section 301, the temperature of another part of the steam can be reduced, thereby reducing the amount of steam and the temperature of steam sprayed from the steam exhaust hole 102, effectively eliminating the safety hazard of steam scalding people, and improving the user experience.

[0082] In some embodiments, the baffle plate 50 can split and guide the steam entering the airflow section 301, so that the steam can enter the next airflow section 301.

[0083] In combination Figure 2 and Figure 3 In some embodiments, in order to increase the resistance of steam flow, the airflow section 301 has a steam outlet end, and the baffle plate 50 is located between the steam inlet hole 101 and the steam outlet end, that is, the baffle plate 50 is located on the steam exhaust path. The steam entering the airflow section 301 from the steam inlet hole 101 will first impact the baffle plate 50, and then enter the adjacent airflow section 301 from the steam outlet end of the airflow section 301, so that the baffle plate 50 can block the steam, increase the resistance of steam flow, reduce the steam flow speed, prolong the time of steam in the airflow section 301, so that the steam has sufficient time to condense in the airflow section 301, part of the steam is condensed into water droplets, the amount of steam exhausted is reduced, at the same time, another part of the steam has sufficient time to cool down in the airflow section 301, the temperature of another part of the steam can be reduced, thereby reducing the amount of steam and the temperature of steam sprayed from the steam exhaust hole 102, effectively eliminating the safety hazard of steam scalding people, and improving the user experience.

[0084] In combination Figure 1 , Figure 2 and Figure 3In some embodiments, in order to make the steam enter into the next air flow channel due to the air flow channel communicated by the steam inlet hole 101, the length of the baffle 50 is smaller than the width of the air flow section 301, that is, there is a spacing between the baffle 50 and the enclosure 20, so that the steam can flow in the air flow channel.

[0085] In combination Figure 2 and Figure 3 In some embodiments, in order to make the steam flow smoothly through the baffle 50, the cross-sectional shape of the baffle 50 is arc-shaped, which is transitioned by a circular arc, can smoothly guide the steam, can reduce the impact force of the steam impacting the baffle 50, ensure the stability of the installation of the baffle 50, improve the service life of the baffle 50, and at the same time, can reduce the noise and improve the user experience.

[0086] In combination Figure 2 and Figure 3 In some embodiments, in order to further make the steam flow smoothly through the baffle 50, the recess direction of the baffle 50 is opposite to the steam exhaust direction, which can smoothly guide the steam and further reduce the impact force of the steam impacting the baffle 50, ensure the stability of the installation of the baffle 50, improve the service life of the baffle 50, and at the same time, can further reduce the noise and improve the user experience.

[0087] In combination Figure 4 In some embodiments, in order to increase the resistance of steam flow, the same air flow section 301 has a steam inlet end and a steam outlet end, and there is a height difference between the steam inlet end and the steam outlet end. The air flow section 301 is arranged obliquely between the steam inlet end and the steam outlet end. By staggered arrangement of high and low, the resistance of steam flow is increased, the steam flow speed is reduced, the time of steam in the air flow channel 30 is prolonged, so that the steam has sufficient time to condense in the air flow channel 30, part of the steam is condensed into water droplets, the amount of steam discharged is reduced, and at the same time, another part of the steam has sufficient time to cool in the air flow channel 30, the temperature of another part of the steam is reduced, thereby reducing the amount of steam sprayed from the steam exhaust hole 102 and reducing the temperature of the steam, effectively eliminating the safety hazard of steam scalding, and improving the user experience.

[0088] In combination Figure 1 , Figure 2 and Figure 3 In some embodiments, in order to make the steam of the steam inlet hole 101 enter the air flow section 301, a flow guide channel 60 is arranged in the shell 10 and communicated with the air flow section 301, and the steam inlet hole 101 is located in the flow guide channel 60. The steam discharged from the steam inlet hole 101 is guided into the air flow section 301 through the flow guide channel 60, so that the steam of the steam inlet hole 101 can enter the air flow section 301, and steam leakage of the steam inlet hole 101 is avoided.

[0089] In some embodiments, in order to form the flow channel 60, the cover further comprises a flow guide 70. The flow guide 70 surrounds the flow channel 60 and is connected with the two innermost surrounding shells 20 to guide the steam discharged from the steam inlet hole 101 into the airflow section 301, so that the steam from the steam inlet hole 101 can enter the airflow section 301 and avoid leakage.

[0090] Figure 5 For Figure 1 Schematic diagram of the arrangement of the flow guide of the cover; Figure 6 For Figure 5 Schematic diagram of the structure of the flow guide. In combination Figure 5 And Figure 6 In some embodiments, in order to prevent the condensed water from flowing out of the steam inlet hole 101 when the cover is turned over, the cover further comprises a flow guide 110 and a counterweight 102. The flow guide 110 is rotatably arranged on the shell 10, and the flow guide 110 and the airflow channel 30 are located on opposite sides of the shell 10, respectively. The flow guide 110 has a flow guide channel 1101 and an airflow inlet 1102 communicating with the flow guide channel 1101, and the flow guide channel 1101 communicates with the steam inlet hole 101. The counterweight 120 is arranged at one end of the flow guide 110. Among them, the airflow inlet 1102 is located at the end of the flow guide 110 away from the counterweight 120.

[0091] In some embodiments, when it is necessary to open the cover on the electrical appliance or the electrical appliance is tilted, under the action of gravity, the counterweight 102 drives the flow guide 110 to rotate on the shell 10, so that the counterweight 102 is located below the vertical direction and the airflow inlet 1102 is located above the vertical direction. The condensed water in the airflow channel 30 cannot flow out through the airflow inlet 1102, avoiding scalding accidents and improving user experience. When the electrical appliance is in normal use, steam can enter the flow guide channel 1101 through the airflow inlet 1102 and then enter the airflow channel 30 through the steam inlet hole 101, so that the steam can be condensed in the airflow channel 30.

The steam flow path is lengthened by the steam outlet channel, and the steam can be fully condensed in the airflow section 301, so that part of the steam is condensed into water droplets, reducing the amount of steam discharged. At the same time, the temperature of another part of the steam can be reduced, thereby reducing the amount of steam sprayed from the steam outlet hole 102 and the temperature of the steam, effectively eliminating the safety hazard of steam scalding, and improving the user's experience. The enclosure is mounted on the upper cover 100 and has a spacing between the bottom of the shell 10, so that the condensed water in the airflow section 301 with a gradually decreasing bottom height can flow into the steam inlet hole 101 through the gap.
