Description

Technical Field

[0001] The utility model relates to the technical field of small household appliances, and in particular to a pot body structure and a cooking utensil having the same. Background Art

[0002] In the related art, a multi-cavity pot (such as a mandarin duck pot) can cook a variety of foods in one pot, enriching the user experience. Since the food cooked in each cavity is different, the required heating amount is generally different.

[0003] In this regard, there are generally two heating schemes in the relevant technology. One scheme is to cook food with the heating time required for food that is not easy to cook, but this will make the cooking time of relatively easy-to-cook food too long and affect the taste of the food; the other scheme is to set multiple heating elements for multiple cavities respectively to achieve independent heating. Although this ensures the taste of the food in each cavity, the structure of the cooking appliance is complicated and the control program is relatively complicated, which makes the cost of the cooking appliance relatively high. Utility Model Content

[0004] The main purpose of the present invention is to provide a pot structure and a cooking utensil having the same, so as to solve the problem in the related art that multi-cavity pots are difficult to give consideration to both the cooking taste of food and low manufacturing cost.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a pot body structure is provided, including: a pot body main body; a partition portion, which is arranged in the pot body main body and separates a first cavity and a second cavity that are independent of each other in the lateral direction in the pot body; and a coating structure, which is arranged on the inner side and / or outer side of the bottom wall of the pot body so that the thermal conductivity of the bottom wall of the first cavity is higher than the thermal conductivity of the bottom wall of the second cavity.

[0006] By applying the technical solution of the present invention, the partition separates the first cavity and the second cavity into independent ones in the pot body, and different foods are placed in the first cavity and the second cavity during cooking. The coating structure is arranged on the inner side and / or the outer side of the bottom of the pot body, so that the thermal conductivity of the bottom wall of the first cavity is higher than the thermal conductivity of the bottom wall of the second cavity. Foods that are relatively difficult to cook, such as root vegetables, whole grains, beans, harder meats, etc., can be placed in the first cavity, and foods that are relatively easy to cook, such as leafy vegetables, tofu, noodles, etc., can be placed in the second cavity. Since the thermal conductivity of the bottom wall of the first cavity is different from the thermal conductivity of the bottom wall of the second cavity, the same heating element can be used to heat the first cavity and the second cavity at the same time, and the foods in the first cavity and the second cavity can be cooked in a similar time, ensuring the taste of the food in the two cavities. Therefore, the technical solution of the present application can effectively solve the problem in the related art that multi-cavity pots are difficult to balance the cooking taste of food and low manufacturing costs.

[0007] Furthermore, the coating structure includes a first metal powder layer disposed on the outer side of the bottom wall of the first cavity and a second metal powder layer disposed on the outer side of the bottom wall of the second cavity, wherein the first metal powder layer and the second metal powder layer are made of different materials. This arrangement enables the first cavity and the second cavity to have different thermal conductivities.

[0008] Furthermore, the first metal powder layer is an iron powder layer, and the second metal powder layer is a SUS430 powder layer. Iron powder has a higher heat generation efficiency than SUS430 powder. Using the iron powder layer as the first metal powder layer and the SUS430 powder layer as the second metal powder layer can achieve a higher thermal conductivity of the bottom wall of the first cavity than that of the bottom wall of the second cavity.

[0009] Furthermore, the thickness of the iron powder layer is greater than or equal to 50 μm and less than or equal to 100 μm; and / or the thickness of the SUS430 powder layer is greater than or equal to 60 μm and less than or equal to 80 μm. This configuration can achieve a higher thermal conductivity of the first cavity than that of the second cavity.

[0010] Furthermore, the cladding structure includes a third metal powder layer disposed on the outside of the bottom wall of the first cavity and a fourth metal powder layer disposed on the outside of the bottom wall of the second cavity. The third and fourth metal powder layers are made of the same material, and the density of the third metal powder layer is greater than that of the fourth metal powder layer. By using metal powders of the same material but different densities to achieve a higher thermal conductivity for the bottom wall of the first cavity than for the bottom wall of the second cavity, only one type of metal powder is required, simplifying the materials and processing required for manufacturing the pot structure.

[0011] Furthermore, the third metal powder layer and the fourth metal powder layer are both iron powder layers, and the density of the third metal powder layer is greater than or equal to 6 g / cm 2 And less than or equal to 8g / cm 2 The density of the fourth metal powder layer is greater than or equal to 3g / cm 2 And less than or equal to 4g / cm 2 This arrangement enables the thermal conductivity of the first cavity to be higher than the thermal conductivity of the second cavity.

[0012] Furthermore, the coating structure includes a first coating layer disposed on the inner side of the bottom wall of the first cavity and a second coating layer disposed on the inner side of the bottom wall of the second cavity, wherein the first coating layer and the second coating layer are made of different materials. This arrangement enables the first cavity and the second cavity to have different thermal conductivities.

[0013] Furthermore, the first coating is a ceramic coating and the second coating is a Teflon coating. Ceramic has a higher thermal conductivity than Teflon. By using the ceramic coating as the first coating and the Teflon coating as the second coating, the thermal conductivity of the bottom wall of the first cavity can be higher than the thermal conductivity of the bottom wall of the second cavity.

[0014] Furthermore, the thickness of the first coating layer is greater than or equal to 100 μm and less than or equal to 500 μm; and / or the thickness of the second coating layer is greater than or equal to 25 μm and less than or equal to 50 μm. This configuration can achieve a higher thermal conductivity of the first cavity than that of the second cavity.

[0015] According to another aspect of the present invention, a cooking appliance is provided, comprising a pot structure and a heating element, wherein the pot structure is the pot structure described above, and the heating element is disposed below the pot structure. This pot structure effectively solves the problem of multi-cavity pots in the related art that it is difficult to achieve a good balance between cooking food and low manufacturing costs. Cooking appliances having this pot structure also have the aforementioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0028] like Figure 1 and Figure 2 As shown, an embodiment of the pot assembly of the present application includes: a pot body 10, a partition 20, and a coating structure. The partition 20 is disposed within the pot body 10 and separates a first cavity 101 and a second cavity 102 that are independent of each other in the transverse direction within the pot body 10. The coating structure is disposed on the inner side and / or outer side of the bottom wall of the pot body 10 so that the thermal conductivity of the bottom wall of the first cavity 101 is higher than that of the bottom wall of the second cavity 102.

[0029] By applying the technical solution of this embodiment, the partition 20 separates the first cavity 101 and the second cavity 102 which are independent of each other in the pot body 10 , and different foods are placed in the first cavity 101 and the second cavity 102 during cooking. The coating structure is disposed on the inner and / or outer sides of the bottom of the pot body 10, so that the thermal conductivity of the bottom wall of the first cavity 101 is higher than that of the bottom wall of the second cavity 102. Foods that are relatively difficult to cook, such as root vegetables, whole grains, beans, and harder meats, can be placed in the first cavity 101, while foods that are relatively easy to cook, such as leafy vegetables, tofu, and noodles, can be placed in the second cavity 102. Because the thermal conductivity of the bottom wall of the first cavity 101 and the thermal conductivity of the bottom wall of the second cavity 102 are different, the same heating element can be used to heat the first and second cavities 101, 102 simultaneously, achieving zoned heating. This allows the foods in the first and second cavities 101, 102 to be cooked in a similar amount of time, ensuring the same taste for the foods in both cavities. Therefore, the technical solution of this embodiment can effectively solve the problem in the related art of multi-cavity pots that it is difficult to strike a balance between the cooking taste of food and low manufacturing costs.

[0030] like Figure 1 and Figure 2 As shown, this embodiment uses a double-cavity pot as an example to illustrate the solution of the present application. In an embodiment not shown in the figure, the pot body may also have three or more cavities.

[0031] Existing heating methods for the pot body 10 are generally divided into two categories: one is heating using a heat source, and the other is IH heating (electromagnetic heating). When using a heat source for heating, the above-mentioned "thermal conductivity" refers to the heat conduction efficiency of the bottom wall of the pot body 10. A higher thermal conductivity means more heat is transferred per unit time. When using IH heating, the above-mentioned "thermal conductivity" refers to the heat generation efficiency of the bottom wall of the pot body 10. A higher thermal conductivity means more heat is generated by the bottom wall per unit time.

[0032] In the first embodiment of the present application, the coating structure includes a first metal powder layer disposed on the outer side of the bottom wall of the first cavity 101 and a second metal powder layer disposed on the outer side of the bottom wall of the second cavity 102. The first metal powder layer and the second metal powder layer are made of different materials. The metal powder layer is sprayed on the bottom wall of the pot body primarily for IH heating pot structures. By spraying the first and second metal powder layers with different materials, the thermal conductivity of the bottom wall of the first cavity 101 and the bottom wall of the second cavity 102 are different.

[0033] Among them, the junction of the first metal powder layer and the second metal powder layer is located at the partition 20, and the first metal powder layer and the second metal powder layer can be arranged only on the bottom wall of the pot body 10, or on both the bottom wall and the outer wall of the pot body 10.

[0034] Specifically, the first metal powder layer is an iron powder layer, and the second metal powder layer is a SUS430 powder layer. Iron powder has a higher heat generation efficiency than SUS430 powder. By using an iron powder layer as the first metal powder layer and an SUS430 powder layer as the second metal powder layer, the thermal conductivity of the bottom wall of the first cavity 101 can be higher than that of the bottom wall of the second cavity 102.

[0035] The thickness of the iron powder layer is greater than or equal to 50 μm and less than or equal to 100 μm; the thickness of the SUS430 powder layer is greater than or equal to 60 μm and less than or equal to 80 μm. Preferably, the thickness of the iron powder layer can be 50 μm, 75 μm, or 100 μm; the thickness of the SUS430 powder layer can be 60 μm, 70 μm, or 80 μm.

[0036] In the second embodiment of the present application, the cladding structure includes a third metal powder layer disposed on the outer side of the bottom wall of the first cavity 101 and a fourth metal powder layer disposed on the outer side of the bottom wall of the second cavity 102. The third and fourth metal powder layers are made of the same material, and the density of the third metal powder layer is greater than that of the fourth metal powder layer. By using metal powders of the same material but different densities to achieve a higher thermal conductivity for the bottom wall of the first cavity 101 than for the bottom wall of the second cavity 102, only one type of metal powder is required, simplifying the materials and processing required for the pot structure.

[0037] Among them, the junction of the third metal powder layer and the fourth metal powder layer is located at the partition 20, and the third metal powder layer and the fourth metal powder layer can be arranged only on the bottom wall of the pot body 10, or on both the bottom wall and the outer wall of the pot body 10.

[0038] It should be noted that the above-mentioned "density" refers to the mass of metal powder per unit area. Specifically, the third metal powder layer and the fourth metal powder layer are both iron powder layers, and the density of the third metal powder layer is greater than or equal to 6g / cm 2 And less than or equal to 8g / cm 2 The density of the fourth metal powder layer is greater than or equal to 3g / cm 2 And less than or equal to 4g / cm 2The metal layer is generally formed on the outside of the pot body 10 by spraying. The density of the metal powder can be changed by changing the number of spraying times. That is, the number of spraying times when processing the third metal powder layer is greater than the number of spraying times when processing the fourth metal powder layer. Preferably, the density of the third metal powder layer can be 6g / cm 2 , 7g / cm 2 or 8g / cm 2 The density of the fourth metal powder layer can be 3g / cm 2 、3.5g / cm 2 or 4g / cm 2 .

[0039] In the third embodiment of the present application, the coating structure includes a first coating disposed on the inner side of the bottom wall of the first cavity 101 and a second coating disposed on the inner side of the bottom wall of the second cavity 102. The first coating and the second coating are made of different materials. The coating on the inner side of the bottom wall of the pot body 10 is primarily intended for pot structures that utilize a heat source for heating. By disposing the first and second coatings of different materials, the thermal conductivity of the bottom wall of the first cavity 101 and the bottom wall of the second cavity 102 are different.

[0040] Among them, the first coating is arranged on the entire cavity wall of the first cavity 101 (including the inner side of the bottom wall of the pot body 10, the inner side of the side wall of the pot body 10, and the side wall of the partition 20 facing the first cavity 101), and the second coating is arranged on the entire cavity wall of the second cavity 102 (including the inner side of the bottom wall of the pot body 10, the inner side of the side wall of the pot body 10, and the side wall of the partition 20 facing the second cavity 102).

[0041] Specifically, the first coating is a ceramic coating, and the second coating is a Teflon coating. Ceramic has a higher thermal conductivity than Teflon. By using the ceramic coating as the first coating and the Teflon coating as the second coating, the thermal conductivity of the bottom wall of the first cavity 101 can be higher than that of the bottom wall of the second cavity 102.

[0042] The thickness of the first coating layer is greater than or equal to 100 μm and less than or equal to 500 μm; the thickness of the second coating layer is greater than or equal to 25 μm and less than or equal to 50 μm. Preferably, the thickness of the first coating layer may be 100 μm, 300 μm, or 500 μm; the thickness of the second coating layer may be 25 μm, 35 μm, 45 μm, or 50 μm.

[0043] like Figure 3As shown, the present application also provides a cooking utensil comprising a pot structure and a heating element, wherein the pot structure is the pot structure described above, and the heating element is disposed below the pot structure. The above pot structure can effectively solve the problem of multi-cavity pots in the related art that it is difficult to achieve both a good cooking taste and low manufacturing cost. Cooking utensil having the above pot structure also has the above advantages.

[0044] like Figure 3 As shown, the cooking appliance further includes a pot body 30 and a cover body 40 which is openably and closably arranged above the pot body 30 . The pot structure and the heating element are both arranged in the pot body 30 .

[0045] In the present embodiment, the cooking utensil is an electric cooker. Of course, in embodiments not shown in the figures, the cooking utensil can also be products such as an electric rice cooker, a low-pressure rice cooker, a soybean milk maker, a food processor, a cooking machine, an electric stew pot, a multi-function pot, etc.

[0046] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0047] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0048] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
