The cooking utensil usually includes casing and inner bag, and the inner bag is used for holding edible material, and the casing suit is outside the inner bag for the protection inner bag, and in order to guarantee that the inner bag is stable, the casing should have good intensity and non-deformable. The shell can be made of metal, the metal plate is connected after being curled during forming to form a cylindrical shell, and when the reliability of the metal plate after being curled and connected is low, the appearance size of the shell is unstable, the shell is released, the service life of the cooking appliance is influenced, and the safety of the cooking appliance is reduced.
SUMMERY OF THE UTILITY MODEL
The application provides a casing and a cooking appliance, wherein the casing has high reliability, and the service life of the casing is prolonged.
A first aspect of the present application provides a housing, including a metal plate, two ends of the metal plate respectively having a first connection portion and a second connection portion; the first connecting portion and the second connecting portion are at least partially overlapped, the overlapped area of the first connecting portion and the second connecting portion is provided with a protruding portion, the protruding portion is provided with an accommodating cavity, and the first connecting portion and the second connecting portion are fixedly connected through the protruding portion.
In this application, when first connecting portion and second connecting portion overlap, can improve the intensity of this casing at hookup location, thereby improve connection reliability, simultaneously, when first connecting portion and second connecting portion are connected through the bellying cooperation of the two, this bellying can play the effect that first connecting portion of restriction and second connecting portion throw off, thereby improve the connection reliability of the two, reduce the casing because of the risk that hookup location breaks off and damages, improve the life of casing.
In one possible design, a side wall of the protruding portion connected to the first connecting portion or the second connecting portion is inclined, that is, in a thickness direction of the housing, the side wall of the protruding portion is inclined so that a sectional area of an opening of the protruding portion is smaller than a sectional area of an inside of the protruding portion, and when an external force is applied in the thickness direction of the housing, since the sectional area of the opening is smaller, disengagement of the mating protruding portion can be restricted, thereby further improving connection reliability between the first connecting portion and the second connecting portion.
In one possible design, the depth of the accommodating cavity is 0.8mm to 5 mm. If the depth of the accommodating cavity is too small (for example, less than 0.8mm), the matching area between the protruding part of the first connecting part and the protruding part of the second connecting part is small, so that the connection reliability of the two protruding parts is low, and the risk of disengagement exists; if the degree of depth that holds the chamber is too big (for example be greater than 5mm), then in the cold-heading in-process, the deflection of first connecting portion and second connecting portion is too big, leads to the intensity of first connecting portion and second connecting portion to be lower, reduces the intensity of casing, and when the degree of depth that holds the chamber was too big, still leads to the bellying to occupy the casing along the space of thickness direction great, is unfavorable for realizing cooking utensil's miniaturization. Therefore, in this embodiment, when the depth of the accommodating cavity is 0.8mm to 5mm, the connection reliability between the two protruding portions is high, and the strength of the first connecting portion and the second connecting portion is also high, so as to improve the strength of the housing.

In a possible design, the bulge does overlap the region and form after the cold-heading extrusion, and the cold-heading technology is gone on under normal atmospheric temperature condition, when realizing first connecting portion and second connecting portion mechanical connection, can also improve mechanical connection's reliability, this is because the metal fiber of cold-heading processing product can not be cut off, the metal inner structure is compacted to and the existence that accompanies the work hardening phenomenon, so the metal mechanical properties after connecting has been improved, and the course of working need not to go on under high temperature, thereby make the hookup location can not produce thermal stress, further improve and connect the reliability. In addition, the cold heading process does not need to cut a product to be processed, so that the material utilization rate can be improved, and auxiliary materials do not need to be introduced in the processing process, so that the materials are saved.
In a possible design, both ends of the metal plate are respectively provided with a first positioning portion and a second positioning portion, the first connecting portion and the second connecting portion are overlapped in the process, the first positioning portion and the second positioning portion are matched and used for limiting the positions of the first connecting portion and the second connecting portion, so that the first connecting portion and the second connecting portion are prevented from being deviated in the cold heading process, and the stability of the first connecting portion and the second connecting portion in the cold heading process is improved.
In one possible design, the thickness of the metal plate is 0.3mm to 2mm, and after connection, the sum of the thicknesses of the first connection part and the second connection part is less than twice of the thickness of the metal plate. If the thickness of the metal plate is too small (for example, less than 0.3mm), the strength and rigidity of the metal plate are small, the strength and rigidity of the housing formed of the metal plate are small, and the metal plate has a large risk of damage during cold heading; if the thickness of the metal plate is too large (for example, larger than 2mm), the metal plate is not easy to deform, the extrusion force required in the cold heading process is large, the energy consumption is large, and meanwhile, the weight of the metal plate is too large, which is not beneficial to realizing the lightness and thinness of the cooking utensil and causes material waste.

The following description will be given taking a cooking appliance, specifically, a liquid heating container, as an example.
As shown in fig. 1, when the cooking device is a liquid heating container, the cooking device comprises a shell 1, a liner 2 and a handle 3, wherein the shell 1 is sleeved outside the liner 2 and is fixedly connected with the handle 3, and a handle cover 31 is detachably connected or fixedly connected with the handle 3. In order to ensure the stability of the inner container 2, the shell 1 should have good strength and not easy to deform. At present common casing is mostly metal casing to the casing of two steel and half two steel insulating pot is the example, and the forming process of this casing is: after the metal plate is curled, the metal plate is riveted or buckled through the riveting strip, the reliability of the two connection modes is low, and when the cooking appliance is used for a long time, the metal plate is in the risk of being separated from the connection position, so that the shell is damaged, the service life of the cooking appliance is shortened, and the safety of the cooking appliance is reduced.
To solve the technical problem, the application embodiment provides a casing 1, as shown in fig. 3 and 4, the casing 1 includes a metal plate, the two ends of the metal plate respectively have a first connecting portion 11 and a second connecting portion 12, after the metal plate is curled, the first connecting portion 11 and the second connecting portion 12 at least partially overlap, the overlapping region of the two portions has a protruding portion 13, the protruding portion has a receiving cavity 132, the protruding portion 13 is protruded on one side of the metal plate, and the other side of the metal plate is recessed, that is, the protruding portion 13 is protruded on the outer side of the casing 1 and recessed on the inner side of the casing 1, or the protruding portion 13 is recessed on the outer side of the casing 1 and protruded on the inner side of the casing 1. The first connecting portion 11 and the second connecting portion 12 are connected by the protruding portion 13, that is, the protrusion 131 of the first connecting portion 11 is connected with the protruding portion 13 of the second connecting portion 12.
In this embodiment, when the first connecting portion 11 and the second connecting portion 12 are overlapped, the strength of the housing 1 at the connecting position can be improved, so that the connection reliability is improved, and meanwhile, when the first connecting portion 11 and the second connecting portion 12 are connected in a matching manner through the protruding portions 13 of the first connecting portion and the second connecting portion, the protruding portions 13 can play a role in limiting the disengagement of the first connecting portion 11 and the second connecting portion 12, so that the connection reliability of the first connecting portion and the second connecting portion is improved, and the risk that the housing 1 is damaged due to the disengagement of the connecting position is reduced.
Specifically, the first connection portion 11 and the second connection portion 12 may be connected by a cold heading process, that is, the protrusion 13 of the first connection portion 11 and the second connection portion 12 may be formed by extrusion by a cold heading process, and a connection point formed after the cold heading is the protrusion 13.
As shown in fig. 5, the apparatus for the cold heading process includes a male die 5 and a female die 4, the female die 4 has a cavity, the first connecting portion 11 and the second connecting portion 12 to be connected are overlapped and placed on the female die 4 during the cold heading process, the overlapped first connecting portion 11 and the overlapped second connecting portion 12 are pressed by the male die 5, the male die 5 corresponds to the cavity of the female die 4 during the cold heading process, so that the overlapped first connecting portion 11 and the overlapped second connecting portion 12 are deformed by the pressing action of the male die 5, the cavity of the female die 4 is used for accommodating the deformed first connecting portion 11 and the deformed second connecting portion 12, that is, the cavity of the female die 4 is used for accommodating the protruding portion 13, and the shape of the protruding portion 13 matches with the shape of the cavity. Through the cold heading process, the first connecting portion 11 and the second connecting portion 12 can be connected, in the process, the first connecting portion 11 and the second connecting portion 12 made of metal are subjected to plastic deformation and flow, and the die cavity is used for containing the flowing metal.
The cold heading process is performed under normal temperature conditions, and the mechanical connection reliability can be improved while the mechanical connection of the first connecting portion 11 and the second connecting portion 12 is realized, because the metal fibers of a cold heading processed product cannot be cut off, the metal internal structure is compacted, and the phenomenon of work hardening is accompanied, so that the mechanical property of the connected metal is improved, and the processing process is not required to be performed at high temperature, so that the thermal stress cannot be generated at the connecting position, and the connection reliability is further improved. In addition, the cold heading process does not need to cut a product to be processed, so that the material utilization rate can be improved, and auxiliary materials do not need to be introduced in the processing process, so that the materials are saved.
Therefore, the protruding portion 13 formed through the cold heading process can be used not only to connect the first connection portion 11 and the second connection portion 12, but also to accommodate a metal material flowing during the cold heading process, so that the flatness of the positions of the first connection portion 11 and the second connection portion 12 other than the protruding portion 13 is high.
The first connecting portion 11 and the second connecting portion 12 may be integrally formed with a metal plate, one side of the metal plate may be provided with one or more first connecting portions 11, the other side of the metal plate may be provided with one or more second connecting portions 12, and each of the first connecting portions 11 and each of the second connecting portions 12 may be provided with the protruding portion 13.
Specifically, as shown in fig. 6, the protruding portion 13 located at the first connecting portion 11 and the second connecting portion 12 includes a side wall 131, and the side wall 131 of the protruding portion 13 connected to the first connecting portion 11 or the second connecting portion 12 is inclined, that is, the side wall 131 of the protruding portion 13 is inclined in the thickness direction of the housing 1, so that the sectional area of the opening of the protruding portion 13 is smaller than the sectional area inside the protruding portion 13, and when an external force is applied in the thickness direction of the housing 1, since the sectional area of the opening is smaller, the protrusion 13 can be prevented from being disengaged, thereby further improving the connection reliability between the first connecting portion 11 and the second connecting portion 12.
Specifically, the included angle between the side wall 131 of the protruding portion 13 and the first connecting portion or the second connecting portion is an inclined angle, and the size of the inclined angle is 15 ° to 75 °, for example, the inclined angle may be 30 °, 40 °, 45 °, 60 °, and the like. In this angular range, the size of the opening of the boss 13 can restrict the boss 13 from coming off from each other, and can avoid large stress concentration in the boss 13.
Specifically, the depth of the accommodating chamber 132 is 0.8mm to 5mm, for example, the depth of the accommodating chamber 132 may be 0.8mm, 1mm, 2mm, 2.5mm, 3mm, 4mm, 5mm, or the like.
Specifically, if the depth of the receiving cavity 132 is too small (for example, less than 0.8mm), the fitting area between the protruding portion 13 of the first connecting portion 11 and the protruding portion 13 of the second connecting portion 12 is small, so that the connection reliability of the two protruding portions 13 is low, and there is a risk of disengagement; if the depth of the accommodating cavity 132 is too large (for example, greater than 5mm), the deformation amount of the first connecting portion 11 and the second connecting portion 12 is too large during the cold heading process, which results in lower strength of the first connecting portion 11 and the second connecting portion 12 and reduces the strength of the housing 1, and when the depth of the accommodating cavity 132 is too large, the space occupied by the protruding portion 13 in the thickness direction of the housing 1 is also large, which is not favorable for realizing the miniaturization of the cooking appliance.
Therefore, in the present embodiment, when the depth of the accommodating cavity 132 is 0.8mm to 5mm, the connection reliability between the two protruding portions 13 is high, and the strength of the first connecting portion 11 and the second connecting portion 12 is also high, thereby improving the strength of the housing 1.
More specifically, when the housing 1 is used for a liquid heating container, the depth of the receiving cavity 132 may be 1mm to 3 mm.
Specifically, the cross-sectional shape of the boss 13 includes one or more of a circle, a rectangle, a triangle, a diamond, and an irregular shape, i.e., the cross-sectional shape of the boss 13 is not limited. Meanwhile, a plurality of protruding portions 13 may be provided for the first connecting portion 11 and the second connecting portion 12, and the cross-sectional shape of each protruding portion 13 may be the same or different, and the specific shape may be selected according to the stress condition in the actual use process. For example, when the housing 1 is subjected to a large external force during use, the triangular, diamond-shaped or rectangular protruding portion 13 may be selected, and the protruding portions 13 of the above shapes can further limit the two protruding portions 13 from being disengaged from each other. When the housing 1 is subjected to a small external force during use, the circular or elliptical protruding portion 13 may be selected, and the stress concentration of the protruding portion 13 of this shape is small, so that the structural strength of the protruding portion 13 can be improved.
In particular, the cross-section of the boss 13 may be circular, the diameter of the boss 13 being greater than or equal to 2mm, such as 3mm, 5mm, etc. If the diameter of the protruding portion 13 is too small, the receiving cavity 132 of the protruding portion 13 is too small, there is a risk that the connection reliability is low because metal flowing in the cold heading process cannot be received, and when the diameter of the protruding portion 13 is larger than 2mm, the diameter of the receiving cavity 132 of the protruding portion 13 is appropriate, so that the connection reliability of the first connection portion 11 and the second connection portion 12 can be improved.
Specifically, the convex portion 13 is provided on the outer side or the inner side of the housing 1, and when the convex portion 13 is provided on the outer side of the housing 1, the convex portion 13 does not occupy the inner space of the housing 1, thereby contributing to the miniaturization of the cooking appliance; when the projection 13 is provided inside the housing 1, the projection 13 does not interfere with other members (e.g., the handle 3) attached to the housing 1.
In the above embodiments, the two ends of the metal plate further have a first positioning portion and a second positioning portion (not shown in the figures), and in the process of overlapping the first connecting portion 11 and the second connecting portion 12, the first positioning portion and the second positioning portion are matched to limit the positions of the first connecting portion 11 and the second connecting portion 12, so that the first connecting portion 11 and the second connecting portion 12 are prevented from shifting in the cold heading process, and the stability of the first connecting portion 11 and the second connecting portion 12 in the cold heading process is improved.
Specifically, the first positioning portion and the second positioning portion are through holes with the same size, and when the first connecting portion 11 and the second connecting portion 12 are overlapped to the correct position to form the overlapping region, the through holes of the first positioning portion and the second positioning portion are overlapped, so as to position the first connecting portion 11 and the second connecting portion 12.
In the above embodiments, the thickness of the metal plate is 0.3mm to 2mm, for example, 0.3mm, 0.8mm, 1mm, 2mm, and the like.
Specifically, if the thickness of the metal plate is too small (for example, less than 0.3mm), the strength and rigidity of the metal plate are small, the strength and rigidity of the housing 1 formed of the metal plate are small, and the metal plate has a large risk of being damaged during cold heading; if the thickness of the metal plate is too large (for example, larger than 2mm), the metal plate is not easy to deform, the extrusion force required in the cold heading process is large, the energy consumption is large, and meanwhile, the weight of the metal plate is too large, which is not beneficial to realizing the lightness and thinness of the cooking utensil and causes material waste.
Specifically, the first connecting portion 11 and the second connecting portion 12 are overlapped, the sum of the thicknesses of the first connecting portion 11 and the second connecting portion 12 before the cold heading extrusion is equal to twice the thickness of the metal plate, after the cold heading extrusion, part of the materials of the first connecting portion 11 and the second connecting portion 12 are pushed into the cavity of the die 4 by the punch 5 to form the convex portion 13, therefore, after the cold heading extrusion, the sum of the thicknesses of the first connecting portion 11 and the second connecting portion 12 is less than twice the thickness of the metal plate, and the cold heading connection of the first connecting portion 11 and the second connecting portion 12 is realized through the flowing of the materials of the first connecting portion 11 and the second connecting portion 12.
The metal plate may be made of stainless steel, stainless iron, galvanized steel, chrome-plated steel, or a composite plate of these materials.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
