Abstract
Description
Technical Field
[0001] The present application relates to the technical field of cookware, and in particular to a cookware. Background Art
[0002] At present, the pot bottoming process has been widely used in pot production. The design purpose is to attach a layer of bottom layer to the outer bottom of the pot to make it suitable for use on induction cookers, and to increase the thickness of the pot bottom to make the heat conduction uniform.
[0003] However, the functions of the pots and pans available for induction cookers on the market are relatively simple, resulting in a poor user experience. Utility Model Content
[0004] The present application provides a cookware, which aims to achieve that the cookware is suitable for an induction cooker and has an anti-slip function and is easy to clean.
[0005] The present application provides a cookware, the cookware comprising:
[0006] A pot body, the pot body having a bottom and a side surrounding portion;
[0007] A composite bottom layer, the composite bottom layer is arranged on the outer side of the bottom;
[0008] An anti-sticking layer, the anti-sticking layer is arranged on a side of the composite bottom layer away from the bottom, and is arranged on the outer side of the side surrounding portion;
[0009] The anti-skid layer is arranged on a side of the anti-sticking layer away from the composite bottom layer, and the anti-skid layer is located at the bottom.
[0010] In the present application, a composite bottom layer, an anti-stick layer and an anti-slip layer are sequentially arranged on the outer side of the bottom of the pot body, so that the pot is suitable for an induction cooker, and the bottom of the pot body also has anti-stick and anti-slip functions, ensuring the stability of the pot during the cooking process, and the pot can be placed in a dishwasher for cleaning, saving manpower.
[0011] In a possible design, when the pot body has a flat bottom, a contact area is provided on the outer side of the bottom, and the anti-slip layer can cover at least a portion of the contact area.
[0012] In the present application, if the outer side of the bottom is a plane, the entire outer side of the bottom is the contact area, and the anti-slip layer can cover the entire contact area to enhance the anti-slip effect. Alternatively, the anti-slip layer can cover part of the contact area to ensure the anti-slip effect while reducing costs.
[0013] In a possible design, when the pot body has a concave bottom, a contact area and a concave area are provided on the outer side of the bottom, and the anti-slip layer can cover at least a portion of the contact area;
[0014] Alternatively, the anti-slip layer can cover at least a portion of the contact area and at least a portion of the recessed area.
[0015] In the present application, if the outer side of the bottom is a concave surface, the outer edge area of the bottom is the contact area, and the middle area of the bottom is the recessed area. At this time, the anti-skid layer can be provided with a variety of coating methods. For example, the anti-skid layer can cover the entire contact area to enhance the anti-skid effect. Alternatively, the anti-skid layer can cover part of the contact area to ensure that the contact position of the bottom of the pot body is on the anti-skid layer while reducing costs. Alternatively, the anti-skid layer can cover the entire contact area and the entire recessed area to further increase the anti-skid effect when the recessed area may be deformed by heat and contact the stove when the pot is cooking. Alternatively, the anti-skid layer can cover part of the contact area and part of the recessed area to ensure the anti-skid effect while reducing costs. Alternatively, the anti-skid layer can cover the entire contact area and part of the recessed area to achieve the anti-skid effect while reducing costs. Alternatively, the anti-skid layer can cover part of the contact area and the entire recessed area to enhance the anti-skid effect of the pot during cooking and reduce the risk of the pot tipping over due to sliding.
[0016] In a possible design, the diameter of the bottom is D1, the maximum diameter of the anti-slip layer is D2, and D1 and D2 satisfy: 5mm≤D1-D2≤8mm.
[0017] In the present application, the difference D1-D2 between the bottom diameter and the anti-slip layer diameter may be 5 mm, 6 mm, 7 mm, 8 mm, etc.
[0018] If D1-D2 is too small (e.g. less than 5mm), the diameter of the anti-slip layer is relatively large. When printing the anti-slip layer, it is easy to reduce the production qualification rate of pots and increase the material cost of the anti-slip layer. If D1-D2 is too large (e.g. greater than 8mm), the diameter of the anti-slip layer is relatively small, and pots with small bottom diameters are easy to tip over, posing a safety risk. Therefore, when D1-D2 is set to meet 5mm≤D1-D2≤8mm, the anti-slip effect of the pot is guaranteed while reducing production costs and defective rates.
[0019] In a possible design, the ratio of the total area of the anti-slip layer to the area of the bottom is S1, and 16%≤S1≤83%.
[0020] In the present application, the ratio of the total area of the anti-slip layer to the area of the bottom can be 20%, 30%, 40%, 50%, 60%, 70%, 80%, etc.
[0021] If the ratio S1 of the total area of the anti-skid layer to the area of the bottom is too small (e.g., S1 is less than 16%), the anti-skid layer at the bottom is too small, the anti-skid effect is poor, and there is a safety risk. If the ratio S1 of the total area of the anti-skid layer to the area of the bottom is too large (e.g., S1 is greater than 16%), when the anti-skid layer is printed, the qualified rate of the pot production is easily reduced, and the cost of the anti-skid layer material is increased.
[0022] In a possible design, when the anti-slip layer completely covers the contact area, an annular area is provided at the outer edge of the anti-slip layer, and the width of the annular area is W, 12 mm≤W≤14 mm.
[0023] In the present application, the width W of the annular area may be 12 mm, 13 mm, 14 mm, etc.
[0024] If the size of W is too large (such as greater than 14mm), the area of the annular region will be larger, increasing the production cost; if the size of W is too small (such as less than 12mm), the pot with a small bottom diameter will easily tip over, posing a safety risk.
[0025] In a possible design, the diameter of the bottom is D1, the diameter of the composite bottom layer is D3, and D1 and D3 satisfy: 10 mm ≤ D1 - D3 ≤ 15 mm.
[0026] In the present application, the difference D1-D3 between the bottom diameter and the complex bottom layer diameter may be 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, or 15 mm.
[0027] If D1-D3 is too small (e.g. less than 10mm), the diameter of the composite bottom layer is relatively large, resulting in a lower production pass rate for the pot and an increase in the cost of the composite bottom layer. If D1-D3 is too large (e.g. greater than 15mm), the diameter of the composite bottom layer is relatively small, resulting in low thermal efficiency of the pot body, affecting the cooking efficiency of the pot. Therefore, when D1-D3 is set to meet 10mm≤D1-D3≤15mm, the cooking efficiency of the pot is guaranteed while reducing production costs and defective rates.
[0028] In a possible design, the ratio of the total area of the composite bottom layer to the area of the bottom is S2, 85%≤S2≤90%.
[0029] In the present application, the ratio of the total area of the composite bottom layer to the area of the bottom can be 85%, 86%, 87%, 88%, 89%, 90%, etc.
[0030] By limiting S2 to satisfy: 85%≤S2≤90%, the area of the composite bottom layer is further increased, and while ensuring the production cost and qualified rate of the cookware, the heating efficiency of the composite bottom layer on the cookware can be further improved.

[0048] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0049] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.
[0051] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.
[0052] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.
[0053] The present embodiment provides a pot 1, which can be applied to an induction cooker, and can be a wok, a soup pot, a steamer, a frying pan, a stew pot, etc. The pot 1 includes a pot body, a pot cover, and a handle. The pot cover can cover the handle body to help speed up the cooking efficiency of the pot 1, and the handle is fixed to the pot body to facilitate taking the pot body. The handle can be a hand-held single-lever handle or a double-ear handle.
[0054] like Figure 1 The figure shows a cross-sectional schematic diagram of a cooker 1, which includes a cooker body 11. The cooker body 11 has a bottom 111 and a side portion 112, and the bottom 111 and the side portion 112 are connected to form a receiving groove for receiving food. The bottom 111 and the side portion 112 are both provided with an inner side and an outer side, the inner side is used to contact with food, and the outer side is used to contact with the external environment (cooking table, cabinet, etc.).
[0055] The material of the pot body 11 can be SS430, which has a fast heating speed and is conducive to improving the cooking efficiency of the pot 1. Alternatively, the material of the pot body 11 can also be 202 to reduce costs.
[0056] like Figure 2 Shown Figure 1 The enlarged schematic diagram of the local structure in FIG. 1 shows that the cookware 1 further includes a composite bottom layer 12 , an anti-sticking layer 13 and an anti-slip layer 14 located on the outside of the bottom 111 of the cookware body 11 .
[0057] Specifically, please refer to Figure 1 and Figure 2The composite bottom layer 12 is arranged outside the bottom 111. The composite bottom layer 12 can be embedded in the bottom 111 or protrude from the bottom 111. Preferably, the composite bottom layer 12 is embedded in the bottom 111 to reduce the thickness of the bottom 111 and make the bottom 111 look neat. By arranging the composite bottom layer 12 in this embodiment, the cookware 1 can be applied to an induction cooker, which is energy-saving and environmentally friendly.
[0058] The anti-sticking layer 13 is disposed on the side of the composite bottom layer 12 away from the bottom 111, and on the outside of the side surrounding portion 112. That is, the outside of the entire structure of the pot body 11 is provided with the anti-sticking layer 13, so that the user can clean the oil stains and black dirt attached to the outside of the pot body 11. Since the outside of the pot 1 is provided with the anti-sticking layer 13, the pot 1 can be placed in a dishwasher for cleaning, which can also produce a better cleaning effect and save the user's time.
[0059] The anti-sticking layer 13 can be formed on the outside of the pot body 11 by spraying, and the material of the anti-sticking layer 13 can be polytetrafluoroethylene (PTFE), which is easy to clean. The anti-sticking layer 13 can be set to red, black, brown, etc.
[0060] The anti-skid layer 14 is located on the outside of the bottom 111 and is arranged on the side of the anti-sticking layer 13 away from the composite bottom layer 12. In this embodiment, the anti-skid layer 14 is arranged to prevent the cookware 1 from slipping, reduce the risk of the cookware 1 being unstable during cooking, improve the safety of the cookware 1, and extend the service life of the cookware 1.
[0061] The anti-skid layer 14 can be formed on the outer side of the pot body 11 by screen printing or spraying. The anti-skid layer 14 can be made of anti-skid printing ink, the main components of which are polytetrafluoroethylene and polyethersulfone resin.
[0062] It should be noted that the anti-skid layer 14 also has an easy-to-clean function. Therefore, after the anti-skid layer 14 covers part of the anti-sticking layer 13 at the bottom 111 of the pot body 11, the outer side of the pot body 11 can still be easily cleaned.
[0063] In this embodiment, the outer side of the bottom 111 of the pot body 11 is provided with a composite bottom layer 12, an anti-stick layer 13 and an anti-slip layer 14 in sequence, so that the pot 1 is suitable for an induction cooker, and the bottom 111 of the pot body 11 also has anti-stick and anti-slip functions, thereby ensuring the stability of the pot 1 during the cooking process, and the pot 1 can be placed in a dishwasher for cleaning, saving manpower.
[0064] Please continue to refer to Figure 1 and Figure 2, a contact area 111a is provided on the outer side of the bottom 111, and the anti-slip layer 14 can cover at least part of the contact area 111a. Specifically, if the outer side of the bottom 111 is a plane, the entire outer side of the bottom 111 is the contact area 111a, and the anti-slip layer 14 can cover the entire contact area 111a to enhance the anti-slip effect, or the anti-slip layer 14 can cover part of the contact area 111a to ensure the anti-slip effect while reducing costs.
[0065] The following specifically describes the ratio of the anti-slip layer 14 to the contact area 111 a when the anti-slip layer 14 covers a portion of the contact area 111 a .
[0066] Please continue to refer to Figure 1 and Figure 2 The diameter of the bottom 111 is D1, the diameter of the anti-slip layer 14 is D2, and D1 and D2 satisfy: 5mm≤D1-D2≤8mm.
[0067] For example, the difference D1-D2 between the diameter of the bottom 111 and the diameter of the anti-slip layer 14 may be 5 mm, 6 mm, 7 mm, 8 mm, etc.
[0068] In this embodiment, if D1-D2 is too small (e.g., less than 5 mm), the diameter of the anti-slip layer 14 is relatively large, and when the anti-slip layer 14 is printed, it is easy to reduce the production qualification rate of the pot 1 and increase the material cost of the anti-slip layer 14. If D1-D2 is too large (e.g., greater than 8 mm), the diameter of the anti-slip layer 14 is relatively small, and the pot with a small bottom diameter is easy to tip over, which poses a safety risk. Therefore, when D1-D2 is set to satisfy 5mm≤D1-D2≤8mm, the anti-slip effect of the pot 1 is guaranteed while reducing the production cost and defect rate.
[0069] Furthermore, the diameter of the bottom 111 is D1, the diameter of the anti-slip layer 14 is D2, and D1 and D2 satisfy: 90%≤D2 / D1≤95%.
[0070] For example, the ratio D2 / D1 of the diameter of the anti-slip layer 14 to the diameter of the bottom 111 may be 90%, 91%, 92%, 93%, 94%, 95%, etc.
[0071] For example, the maximum diameter of the cookware 1 is 14 cm, the diameter D1 of the bottom 111 of the cookware body is 12.6 cm, and the diameter of the anti-slip layer 14D2 is 11.5 cm, then D2 / D1 is 91.2%.
[0072] In this embodiment, by limiting D2 / D1 to satisfy 90%≤D2 / D1≤95%, the diameter of the anti-slip layer 14 is further increased, and while ensuring the production cost and pass rate of the cookware 1, the anti-slip effect of the anti-slip layer 14 on the cookware 1 can be further improved.
[0073] Furthermore, the ratio of the total area of the anti-slip layer 14 to the area of the bottom 111 is S1, and 16%≤S1≤83%.
[0074] Exemplarily, the ratio of the total area of the anti-slip layer 14 to the area of the bottom 111 may be 20%, 30%, 40%, 50%, 60%, 70%, 80%, etc.
[0075] In this embodiment, if the ratio S1 of the total area of the anti-skid layer 14 to the area of the bottom 111 is too small (such as S1 is less than 16%), the anti-skid layer 14 is too small on the bottom 111, the anti-skid effect is poor, and there is a safety risk. If the ratio S1 of the total area of the anti-skid layer 14 to the area of the bottom 111 is too large (such as S1 is greater than 16%), when the anti-skid layer 14 is printed, it is easy to cause the production qualification rate of the pot 1 to decrease, and increase the material cost of the anti-skid layer 14.
[0076] like Figure 3 The figure shows a schematic diagram of the outer side of the bottom 111, in which the pattern is the pattern of the anti-slip layer 14, wherein the circular structure can also be replaced by a square, diamond, triangle or other structure.
[0077] Please continue to refer to Figure 3 The outer edge of the anti-slip layer 14 is provided with an annular area 141 , and the width of the annular area 141 is W, 12 mm≤W≤14 mm.
[0078] Exemplarily, the width W of the annular region 141 may be 12 mm, 13 mm, 14 mm, etc.
[0079] In this embodiment, if the size of W is too large (such as greater than 14 mm), the area of the annular region 141 is larger, increasing the production cost; if the size of W is too small (such as less than 12 mm), the pot with a small bottom diameter is easy to tip over, posing a safety risk.
[0080] In some embodiments, the bottom 111 of some cookware 1 is slightly concave from the outside to the inside, that is, the bottom of the pot body 11 is a concave bottom, so as to enhance the stability of the cookware 1.
[0081] like Figure 4 The bottom 111 of the pot body 11 is slightly concave inwardly, please refer to Figure 3 and Figure 4 , the outer side of the bottom 111 is provided with a recessed area 111b and a contact area 111a, and the annular area 141 can cover at least part of the contact area 111a. Specifically, if the outer side of the bottom 111 is a curved surface, the outer edge area of the bottom 111 is the contact area 111a, and the middle area of the bottom 111 is the recessed area 111b. At this time, the anti-slip layer 14 can be provided with a variety of coating methods.
[0082] Exemplarily, the anti-slip layer 14 may cover the entire contact area 111 a to enhance the anti-slip effect.
[0083] Alternatively, the anti-slip layer 14 may cover part of the contact area 111 a , thereby ensuring that the contact position of the bottom of the pot body 11 is on the anti-slip layer 14 while reducing costs.
[0084] Alternatively, the anti-slip layer 14 may cover the entire contact area 111a and the entire recessed area 111b, so as to further enhance the anti-slip effect when the recessed area 111b may be deformed by heat and contact the stovetop during cooking.
[0085] Alternatively, the anti-skid layer 14 may cover part of the contact area 111a and part of the recessed area 111b, ensuring the anti-skid effect while reducing the cost. Alternatively, the anti-skid layer 14 may cover the entire contact area 111a and part of the recessed area 111b, achieving the anti-skid effect while reducing the cost.
[0086] Alternatively, the anti-slip layer 14 may cover part of the contact area 111a and the entire recessed area 111b to enhance the anti-slip effect of the cookware during cooking and reduce the risk of the cookware 1 tipping over due to sliding.
[0087] Among them, Figure 4 The bottom 111 of the pot body 11 shown can also be configured as follows Figure 3 The anti-slip layer 14 shown in FIG. Figures 1 to 3 The diameter and area of the anti-slip layer 14 of the pot body 11 are also limited to Figure 4 The anti-slip layer 14 of the pot body 11 is not described in detail in this embodiment.
[0088] Please continue to refer to Figure 1 and Figure 2 The diameter of the bottom 111 is D1, the diameter of the composite bottom layer 12 is D3, and D1 and D3 satisfy: 10mm≤D1-D3≤15mm.
[0089] Exemplarily, the difference D1-D3 between the diameter of the bottom 111 and the diameter of the complex bottom layer 12 may be 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, or 15 mm.
[0090] In this embodiment, if D1-D3 is too small (e.g., less than 10 mm), the diameter of the composite bottom layer 12 is relatively large, resulting in a lower production pass rate of the cooker 1 and an increased cost of the composite bottom layer 12. If D1-D3 is too large (e.g., greater than 15 mm), the diameter of the composite bottom layer 12 is relatively small, resulting in low thermal efficiency of the pot body 11, affecting the cooking efficiency of the cooker 1. Therefore, when D1-D3 is set to satisfy 10 mm ≤ D1-D3 ≤ 15 mm, the cooking efficiency of the cooker 1 is guaranteed while reducing production costs and defective rates.
[0091] Furthermore, the diameter of the bottom 111 is D1, the diameter of the composite bottom layer 12 is D3, and D1 and D3 satisfy: 85%≤D3 / D1≤90%.
[0092] For example, the ratio D3 / D1 of the diameter of the composite bottom layer 12 to the diameter of the bottom 111 may be 85%, 86%, 87%, 88%, 89%, 90%, etc.
[0093] For example, the maximum diameter of the pot 1 is 14 cm, the diameter D1 of the bottom 111 of the pot body 11 is 12.6 cm, and the diameter D3 of the composite bottom layer 12 is 10.3 cm, then D3 / D1 is 82.3%.
[0094] In this embodiment, by limiting D3 / D1 to satisfy: 85%≤D3 / D1≤90%, the diameter of the composite bottom layer 12 is further increased, and while ensuring the production cost and pass rate of the cookware 1, the heating efficiency of the composite bottom layer 12 on the cookware 1 can be further improved.
[0095] Furthermore, the ratio of the total area of the composite bottom layer 12 to the area of the bottom 111 is S2, and 85%≤S2≤90%.
[0096] For example, the ratio of the total area of the composite bottom layer 12 to the area of the bottom 111 may be 85%, 86%, 87%, 88%, 89%, 90%, etc.
[0097] In this embodiment, by limiting S2 to satisfy: 85%≤S2≤90%, the diameter of the composite bottom layer 12 is further increased, and while ensuring the production cost and pass rate of the cookware 1, the heating efficiency of the composite bottom layer 12 on the cookware 1 can be further improved.
[0098] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
