The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1, a cooking apparatus 100 according to an embodiment of the present invention, the cooking apparatus 100 includes a pot body 20 and a cover structure 40, and the pot body 20 includes an outer pot 21 and an inner pot 23 accommodated in the outer pot 21. The inner pot 23 comprises a pot bottom wall 232 and a pot side wall 234 formed by extending the edge of the pot bottom wall 232 towards the same direction, wherein the pot side wall 234 surrounds the periphery of the pot bottom wall 232 and forms an open-ended accommodating cavity together with the pot bottom wall 232, and the cover body structure 40 is connected to the outer pot 21 in an openable manner so as to open or close the open end of the inner pot 23. When the cover structure 40 and the pan body 20 are in the closed state, the cover structure 40 and the pan body 20 together form a heating space, and food can be placed in the accommodating cavity and heated in the heating space.
The cover structure 40 in the present application will be described below using the cooking device 100 as an example of an electric rice cooker. The present embodiment is only used as an example and does not limit the technical scope of the present application. It will be appreciated that in other embodiments, the cooking appliance 100 may also be embodied as other appliances, such as a pressure cooker, etc., to which the cover structure 40 is mounted, without limitation.
As shown in fig. 1 and 2, the cover structure 40 includes a cover assembly 41 and a heat insulation cover assembly 43 coupled to one side of the cover assembly 41, the cover assembly 41 is rotatably connected to the outer pot 21, and the heat insulation cover assembly 43 rotates along with the cover assembly 41 relative to the outer pot 21. When the cover structure 40 and the pan body 20 are in a closed state, the heat-preserving cover assembly 43 is positioned on the side of the face cover assembly 41 facing the heating space.
As shown in fig. 3, the insulating cover assembly 43 includes an insulating cover bracket 432, an insulating cover 434, and an insulating cover gasket 436. The thermal insulation cover bracket 432 includes a ring-shaped bracket main body 4321 and a connecting member 4323 connected to one side of the bracket main body 4321, wherein the bracket main body 4321 is connected to the cover assembly 41 through the connecting member 4323 (as shown in fig. 2). The edge of the heat preservation cover 434 is limited to the bracket main body 4321, and the heat preservation cover sealing ring 436 is sleeved on the edge of the heat preservation cover 434 to seal a gap between the heat preservation cover 434 and the pot body 20 (as shown in fig. 1). The center of the thermal insulation cover 434 is further provided with a mounting portion protruding therethrough with a mounting hole for connecting the cover assembly 41, so that the thermal insulation cover 434 is firmly coupled to the cover assembly 41.
As shown in fig. 1 and 2, the insulating cover 434 has an insulating surface 4343a for forming a heating space on a side away from the cover assembly 41. The insulation surface 4343a is located in the heating space and is opposite to the bottom wall 232 when the cover structure 40 and the pot body 20 are in a closed state, and a downward slope trend is formed between the edge area and the central area of the insulation surface 4343a. The edge region of the heat-insulating surface 4343a is an annular region corresponding to the pan side wall 234, and the center region of the heat-insulating surface 4343a is a region provided with an installation portion corresponding to the center of the pan bottom wall 232.
Thus, when the cover structure 40 and the pot body 20 are in a closed state and are in a cooking process, a plurality of small water droplets condensed on the heat preservation surface 4343a continuously flow towards the center of the heat preservation surface 4343a under the action of gravity to be converged into water droplets with larger diameters, and the water droplets with larger diameters further drop into the accommodating cavity in time in the cooking process under the action of gravity. Therefore, after the cooking is completed and the cover body structure 40 is opened, water drops hardly remain on the heat preservation surface 4343a, so that condensed water is prevented from dripping from the heat preservation surface 4343a onto the cooked food or flowing into the groove at the edge of the pot body 20, the problem that the taste of the food is affected due to the dripping of the condensed water into the cooked food or the condensed water overflows out of the pot body 20 from the groove is solved, and an additional condensed water collecting structure is not needed.
As shown in fig. 1 and 4, in some embodiments, the distance between the insulating surface 4343a and the bottom wall 232 of the pan gradually decreases from the edge area to the center area. Therefore, the water drops on the heat preservation surface 4343a at the non-central position are quickly converged into the water drops with larger diameter towards the central area of the heat preservation surface 4343a under the action of gravity, so that the water drops fall into the accommodating cavity in time in the cooking process.
Further, in some embodiments, the edge region to the central region of the insulation surface 4343a extends smoothly with a certain gradient, so that the moving speed of the water droplets on the insulation surface 4343a is further improved, and the water droplets can not stay on the insulation surface 4343a for storage, unlike the scheme that the surface of the insulation cover in the prior art is provided with a plurality of small grooves for storing condensed water. In particular, in one embodiment, the insulating surface 4343a is a smooth conical surface protruding toward the bottom wall 232 of the pot, so that the insulating cover 434 has a maximum water droplet collecting speed within a certain thickness.
It will be appreciated that the specific shape of the heat preservation surface 4343a is not limited, and in other embodiments, the heat preservation surface 4343a may also be an arc surface protruding toward the bottom wall 232 of the pot, the heat preservation surface 4343a may also be a multi-stage structure along the radial direction, the inclination angle of each stage is different, and the water drops on each stage may roll and converge in the direction close to the central area under the action of gravity.
In some embodiments, the distance of the insulating surface 4242a from the bottom wall 232 may also be a discontinuous intermittent decrease from the edge region to the center region. Specifically, in an embodiment, the heat insulation cover 434 is provided with a plurality of annular saw-tooth portions protruding toward the accommodating cavity, the saw-tooth portions are sequentially arranged along the radial direction of the heat insulation cover 434, and the diameter of the saw-tooth portions is gradually reduced from the center of the edge of the heat insulation cover 434, so that a heat insulation surface 4242a with a saw-tooth-shaped longitudinal section is formed, and water drops on each saw-tooth portion are converged at the tip of the saw-tooth portion, which is close to the bottom wall 332, under the action of gravity and quickly drop into the accommodating cavity.
As shown in fig. 5, in particular, in some embodiments, the heat insulation cover 434 includes a base layer 4341 and a hydrophobic layer 4343 covering a side surface of the base layer 4341 facing the pot body 20, and a heat insulation surface 4343a is formed on a side surface of the hydrophobic layer 4343 facing away from the base layer 4341. Thus, the thermal insulation cover 434 has a double-layer structure, and the base layer 4341 can ensure the mechanical strength and thermal insulation performance of the thermal insulation cover 434. The heat preservation surface 4343a has hydrophobicity, so that water drops can flow and gather on the heat preservation surface 4343a rapidly and drop into the pot body 20 rapidly.
More specifically, in some embodiments, the hydrophobic layer 4343 has superhydrophobicity, and is formed of a non-wetting superhydrophobic composite material (e.g., a composite material of type XHC-901 of Xin lotus practice company) coated on one side surface of the base layer 4341, the contact angle θ of the hydrophobic layer 4343 with the water droplet is greater than 150 ° and the rolling angle is less than 10 °, the water droplet is not adsorbed by surface tension on the heat preservation surface 4343a (i.e., the water droplet is not wetted by the heat preservation surface 4343 a), and thus the water droplet attached to the heat preservation cover 434 has a faster moving speed on the heat preservation surface 4343 a. It will be appreciated that the material of the hydrophobic layer 4343 is not limited and different materials may be used as desired. In other embodiments, the insulating cover 434 may also be integrally formed of a hydrophobic material.
Due to the arrangement of the hydrophobic layer 4343, the direct included angle between the heat preservation surface 4343a and the central axis of the heat preservation surface 4343a is greater than 75 degrees and less than 89 degrees, that is, the included angle α between the heat preservation surface 4343a and the horizontal plane is 1 ° -15 degrees (as shown in fig. 4), without setting an excessive inclination angle, so that the thickness of the cover structure 40 is greatly increased, which is beneficial to the miniaturization development of the cooking utensil 100. It will be appreciated that in other embodiments, the included angle α between the heat preservation surface 4343a and the horizontal plane may be greater than 15 ° to further increase the moving speed of the water droplet.
The contact angle θ (contact angle) mentioned above refers to the angle between the tangent line of the gas-liquid interface made at the intersection of the gas, liquid and solid phases and the solid-liquid boundary line; the rolling angle mentioned above refers to a critical angle formed by the inclined surface and the horizontal plane when the liquid drop just rolls on the inclined surface (i.e., the insulation surface 4343 a).
The cover structure 40 and the cooking utensil 100 provided with the cover structure 40, because the cover structure 40 is provided with the super-hydrophobic heat preservation surface 4343a, water vapor generated in the pot body 20 meets the heat preservation surface 4343a, and then water drops formed by condensation on the heat preservation surface 4343a have good mobility on the heat preservation surface 4343a, and because the heat preservation surface 4343a is obliquely arranged, the water drops can rapidly roll towards the center of the heat preservation surface 4343a to be converged into water drops with larger diameters, and finally, the water drops rapidly drop into the pot body 20 under the action of gravity. The water drops drop fast and occur in the cooking process, so that the taste of the food is not affected, and the water loss in the food can be avoided. When the cooking is completed and the lid structure 40 is opened, there is little water drop left on the heat preservation surface 4343a, so that no condensed water drops in the cooked food, and no condensed water flows into the groove at the edge of the pot body 20, so that the taste of the food cooked by the cooking appliance 100 provided with the lid structure 40 is not damaged by the condensed water, and the manufacturing and using costs are increased without additionally providing a condensed water collecting device. Further, since the heat-retaining surface 4343a having hydrophobicity cannot store water vapor, moisture in the cooked food is not lost during the heat-retaining process. In addition, since the heat preservation surface 4343a has hydrophobicity, the heat preservation surface 4343a has a self-cleaning function and is easier to clean, thereby further improving the user experience.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
