Description

Technical Field

[0001] The utility model relates to the technical field of cookware, in particular to a composite material cookware. Background Art

[0002] At present, there are iron pots, aluminum pots and stainless steel pots. Iron pots have health benefits for the human body, but they have poor thermal conductivity, are heavy, easily oxidized, easily damaged and rusted, and have a short service life. Composite material pots are pots made of two or more different materials in order to obtain better performance and use effects. The following are some common types of composite material pots.

[0003] The materials of pots can include pig iron (cast iron), wrought iron (fine iron), aluminum, stainless steel, copper, non-stick pans, ceramic pots, titanium pots and enamel pots, etc. Each material has its own specific advantages and disadvantages. For example, aluminum pots have strong thermal conductivity but are not durable, stainless steel pots are corrosion-resistant and safe and healthy, but non-stick pots need to pay attention to the protection of the coating. A large number of composite materials have been extended, such as iron inside and aluminum outside, stainless steel inside and aluminum outside, three-layer steel, etc. Multi-layer stainless steel composite materials, stainless steel aluminum composite kitchenware, etc., are favored by chefs because of their thermal conductivity, light weight and easy cleaning. Another example is titanium aluminum composite titanium material pots. The composite titanium woks on the market usually have titanium as the food contact layer, and the outer layer uses a pure aluminum and stainless steel composite structure to improve the poor thermal conductivity of pure titanium woks. Since the aluminum composite substrate is stamped and hard-oxidized to enhance the hardness and corrosion resistance of the pot surface, the aluminum sheet layer and the magnetic conductive sheet layer are brazed at the bottom to make the bottom of the pot thicker, not easy to deform, evenly heated, and reduce oil smoke. It can be seen that composite pots are used to improve the performance of pots by combining the advantages of different materials.

[0004] Although composite materials for cookware have been widely used in the market, it is quite rare to use them to make electric hot pots. The main reason is that it is difficult to make composite materials into electric hot pots with the existing heating methods. There are two common heating methods for electric hot pots on the market, each with its own advantages and disadvantages. The following are two common heating methods:

[0005] The first type, split heating, is to place the heating plate at the bottom and the pot body above the heating plate. The pot body is separated from the heating base, and there may be poor contact or loose connection during use, affecting normal heating, and even there are certain safety hazards, which will cause connection stability problems; because it is divided into two parts, the pot body and the base, it requires more space to place when stored, which will make the occupied space relatively large; each time it is used, the pot body needs to be accurately placed on the base, and it needs to be stored separately after use. There are more steps than the integrated type, which makes the operation slightly cumbersome and inconvenient for users; its structure is relatively complex, and the manufacturing and maintenance costs may be slightly higher than the integrated type, which will also make the cost higher; compared with the integrated type, the split design may have a certain energy loss during heat transfer, affecting the heating efficiency.

[0006] The second type, brazing heating, is to directly weld the heating tube to the pot body by brazing, high-frequency welding or laser welding to improve thermal efficiency. This type has strict requirements on the brazing process. If the process does not meet the standards, it may lead to poor welding quality and hidden dangers of failure. Therefore, the process is difficult. Once there is a problem at the brazing point, it is troublesome to repair. It may require professional personnel to handle it, or even the entire component may need to be replaced, which makes repair more difficult. High-quality brazing technology may increase production costs, which is reflected in product prices and is not conducive to large-scale promotion and application. Thermal stress may be generated during welding, and long-term use may affect the stability and life of the pot body and the heating part, which will lead to thermal stress problems. When brazing different materials, the compatibility and matching of the materials are more stringent, and the material matching requirements are higher. It can be seen that this heating method has strong limitations and can only be applied to single-layer materials. For the pot body of composite materials, this welding method is challenging. Because high-temperature welding may cause material stratification, it is difficult to achieve large-scale production.

[0007] In summary, the cookware and the heating plate in the prior art are either separated or welded, which will greatly increase the subsequent maintenance cost and the heating efficiency during use is not very good. Therefore, it is necessary to improve the prior art based on this situation. Utility Model Content

[0029] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the scope of the utility model. In addition, in the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0030] Example 1: See Figure 1 A composite material cookware comprises a pot body 1, which is made of composite materials. A heating unit 2 is arranged on the lower surface of the pot body 1, and the heating unit 2 and the pot body 1 are fixed together by studs 3. The studs 3 and the pot body 1 are arranged together by a butt welding process. The studs 3 are connected to the pot body 1 by means of butt welding, which effectively ensures the close fit between the subsequent heating unit 2 and the pot body 1.

[0031] The utility model fixes the heating unit 2 to the lower surface of the pot body 1 through the stud 3, which solves all the defects of the split type in the prior art in which the heating plate is placed separately at the bottom. The utility model has a stronger connection stability, avoids the problem of poor contact or loose connection, which affects normal heating and potential safety hazards, and is also conducive to reducing the occupied space. The overall design is more novel, and there is no need to store them separately, which is convenient for users to use. The structure is simpler, and the manufacturing and maintenance costs are lower. Among them, the important thing is that the stud 3 is connected to the pot body 1 by means of butt welding, which effectively ensures the close fit between the subsequent heating unit 2 and the pot body 1, significantly improves the heating efficiency, and saves energy.

[0032] Compared with the prior art in which the heating plate is welded to the pot body, the utility model reduces the process requirements. The utility model only needs the heating unit 2 to be fixed to the lower surface of the pot body 1 by the stud 3, and can be disassembled and replaced without the need for professional personnel, which greatly reduces the subsequent maintenance cost and is also conducive to large-scale promotion and application. It is also conducive to ending the thermal stress that may be generated during the welding process, thus avoiding the defects that may affect the stability and life of the pot body and the heating part due to long-term use, and is also conducive to avoiding the problem of more stringent requirements on the compatibility and matching of materials and higher requirements on material matching when brazing between different materials. It can be seen that the utility model is an original design with strong usability.

[0033] Embodiment 2: It can be explained on the basis of embodiment 1, such as Figure 2 and Figure 3As shown, the heating unit 2 includes a heating plate 21 arranged on the lower surface of the pot body 1, a heating tube 22 is arranged on the heating plate 21, and a chamber 23 for accommodating the heating tube 22 is arranged on the heating plate 21. This arrangement is reasonable, simple in structure, and easy to implement. It should be noted that the chamber 23 is located on the lower surface of the heating plate 21, which is conducive to reducing the occupied space, and the heating tube 22 is more novel as a whole after installation. In the utility model, the heating tube 22 is installed in the chamber 23 of the heating plate 21 by external machinery and equipment, rather than by hand. This is conducive to avoiding the loosening or detachment of the heating tube 22, because high temperature will be generated during use. This is not only conducive to significantly improving the heating efficiency and saving energy, but also conducive to improving the safety of use.

[0034] Among them, Figure 2 and Figure 3 As shown, the heating plate 21 is provided with a mounting hole 211 for the stud 3 to pass through, and a nut 4 is provided on the stud 3. The nut 4 is used to lock and fix the heating plate 21 on the lower surface of the pot body 1, which is conducive to the perfect matching of the heating unit 2 and the pot body 1, and can solve the problem of seams or desoldering between materials caused by different thermal expansion coefficients of the composite pot body 1, ensuring uniform heating of the pot body 1. It is to be noted that the number of the stud 3 and the mounting hole 211 is at least two, which is more conducive to fixing the heating plate 21 on the lower surface of the pot body 1.

[0035] Embodiment 3: It can be described on the basis of Embodiment 1 or Embodiment 2, such as Figure 1 , Figure 2 and Figure 3 As shown, a pot handle 5 is provided on the pot body 1, which is convenient for the user to hold it with hands during use. In this embodiment, the pot handles 5 are distributed in pairs on the outer surface of the pot body 1, and the two pot handles 5 are distributed corresponding to each other. This arrangement is more convenient for users to use.

[0036] The heating unit 2 of the utility model is fixed on the lower surface of the pot body 1 by the stud 3, and because the stud 3 and the pot body 1 are set together by the butt welding process, the close fit between the heating unit 2 and the pot body is greatly improved, which not only significantly improves the heating efficiency and saves energy, but also makes it easy to replace the heating unit 2, effectively solves the maintenance problem in after-sales service, and is also conducive to reducing the waste of resources. Through this innovative design, the utility model not only improves the performance of the cooker, but also improves the sustainability and user satisfaction of the product.

[0037] The standard parts used in this application document can all be purchased from the market, and the specific connection methods of each part adopt conventional means such as mature bolts and rivets in the prior art, which will not be described in detail here.

[0038] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model. Therefore, based on the innovative concept of the utility model, changes and modifications made to the embodiments of this article, or equivalent structure or equivalent process changes made using the contents of the utility model specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the utility model patent.
