Description

[Technical Field]

[0001] The present invention relates to the technical field of heating tableware, and more particularly to a heating pan that is commonly used in microwave ovens and ovens. [Background technology]

[0002] A microwave oven is a modern cooking appliance that uses microwaves to heat food. It consists of a power supply, magnetron, control circuit, and cooking chamber. The power supply supplies a high voltage of approximately 4000 volts to the magnetron. The magnetron is excited by the power supply to continuously generate microwaves, which are transmitted into the cooking chamber through a waveguide system. During heating, the generated microwave energy is distributed evenly throughout the cooking chamber to heat the food.

[0003] Some conventional tableware, such as microwave oven heating boxes, include a metal pot body, and when heated, microwaves are blocked by the metal, preventing the food in the metal pot body from being effectively heated through the metal, resulting in a reduced heating effect on the food. Summary of the Invention [Problem to be solved by the invention]

[0004] To solve at least one of the above problems, the present invention provides a heating pot commonly used in microwave ovens and ovens. The pot includes a metal body. A heat-generating composite layer is exposed on the exterior of the metal body. The heat-generating composite layer includes a coating layer, a first microwave-absorbing heating sheet, and a second microwave-absorbing heating sheet. The coating layer is applied to the bottom of the metal body. The first microwave-absorbing heating sheet is attached to one side of the coating layer away from the metal body. The second microwave-absorbing heating sheet is attached to one side of the first microwave-absorbing heating sheet away from the coating layer. The coating layer, the first microwave-absorbing heating sheet, and the second microwave-absorbing heating sheet are all capable of absorbing microwaves and generating heat. When heated by microwaves, the coating layer, the first microwave-absorbing heating sheet, and the second microwave-absorbing heating sheet absorb microwaves, generate heat, and transfer it to the metal body, thereby heating the food in the metal pot. The heating pot according to the present invention, which is commonly used in microwave ovens and ovens, is equipped with a heat-generating composite layer, and the coating layer of the heat-generating composite layer, the first microwave-absorbing heat-generating sheet, and the second microwave-absorbing heat-generating sheet can all absorb microwaves and generate heat, thereby heating the food inside the metal pot and quickly raising the temperature of the food. Furthermore, the heating box can also be used in ovens, making it versatile. [Means for solving the problem]

[0005] Optionally, the heat generating composite layer is installed under the metal pot body. The coating layer is a microwave absorbing paint. The first microwave absorbing heat generating sheet and the second microwave absorbing heat generating sheet are both made of silica gel material, which absorbs microwaves and instantly generates heat to raise the temperature. The melting points of the first microwave absorbing heat generating sheet and the second microwave absorbing heat generating sheet are 230°C to 250°C.

[0006] Optionally, the first microwave absorbing heat generating sheet and the second microwave absorbing heat generating sheet are joined together by abrasive pressing process.

[0007] Optionally, the first microwave absorbing and heat generating sheet is adhered to the coating layer.

[0008] Alternatively, the inner surface of the metal pot body may be coated with a non-stick coating layer, which may be a Teflon coating layer or a ceramic coating layer.

[0009] Optionally, a plurality of supporting protrusions are provided on the underside of the heat generating composite layer.

[0010] Optionally, a plurality of ridges are provided on the inner bottom of the metal pot body.

[0011] Optionally, the metal pot body is provided with a ring, which is provided with a spout and a handle. The ring and the handle are both made of dust-resistant silica gel material. The dust-resistant silica gel material is nano-hydrophobic coated silica gel or anti-static modified silica gel.

[0012] Optionally, the heating pot commonly used in microwave ovens and ovens further includes a lid. The lid is detachably attached to the top of the metal pot body. A positioning rib is provided on the underside of the lid. A first positioning groove is provided on the ring. When the lid is placed in contact with the top of the ring, the positioning rib is positioned within the first positioning groove.

[0013] Optionally, the heating pot commonly used in microwave ovens and ovens further includes an intermediate box. The intermediate box includes a metal plate and an annular bracket connected to the top of the metal plate. Two heat generating composite layers are provided. One heat generating composite layer is attached to the outer bottom of the metal pot body. The other heat generating composite layer is attached to the outer bottom of the metal plate. A first contact portion is annularly attached to the lower side of the annular bracket. A second contact portion corresponding to the first contact portion is attached to the upper side of the annular bracket. A second positioning groove corresponding to the positioning rib is provided on the annular bracket. An inner wall is attached to the second positioning groove. A positioning protrusion is attached to the outer wall of the positioning rib, which abuts against the inner wall of the groove to restrict its position. When the intermediate box is placed in contact with the upper side of the annular bracket, the first contact portion abuts against the second contact portion. When the cover is placed in contact with the upper side of the annular bracket, the positioning rib is positioned within the second positioning groove. [Effects of the Invention]

[0014] Compared with conventional technologies, the heating pot commonly used in microwave ovens and ovens according to the present invention is equipped with a heat-generating composite layer. The coating layer of the heat-generating composite layer, the first microwave-absorbing heating sheet, and the second microwave-absorbing heating sheet all absorb microwaves and generate heat, thereby heating the food inside the metal pot and increasing the food's temperature. Furthermore, the heating box can also be used in ovens, making it versatile. The first and second microwave-absorbing heating sheets are connected using a grinding and pressing process, which provides a tighter bond and prevents the two sheets from separating and becoming damaged. Furthermore, the grinding and pressing process provides excellent high-temperature resistance, making them less likely to separate even at high temperatures, and ensuring a long service life. The underside of the heat-generating composite layer is equipped with multiple support protrusions, which directly transfer the heat generated by microwave heating to the bottom of the metal pot, enhancing the thermal conduction effect, allowing the entire metal pot to heat up more quickly and more effectively. The support protrusions design creates a gap between the heat-generating composite layer and the microwave oven or oven, promoting airflow and improving heating efficiency and uniformity. The heating pot of the present invention, which is generally used in microwave ovens and ovens, has three combination states, making it more flexible to use. [Brief explanation of the drawings]

[0016] In order to make the above-mentioned objects, features and advantages of the present invention clearer and easier to understand, specific embodiments of the present invention will be described in detail below in conjunction with the drawings.

[0017] It should be understood that in describing the present invention, the orientation or positional relationship indicated by terms such as "upper," "lower," etc., is based on the orientation or positional relationship of the product during normal use.

[0018] The terms "first" and "second" are used for descriptive purposes only and cannot be understood as expressing or implying the relative importance or quantity of the indicated technical features. Thus, features qualified by "first" or "second" may include at least one of those features, either expressly or implicitly.

[0019] First Example 1 to 11, a first embodiment of the present invention provides a heating pan commonly used in microwave ovens and ovens, and includes a metal pan body 1. A heat-generating composite layer 2 is exposed on the outside of the metal pan body 1. The heat-generating composite layer 2 includes a coating layer 21, a first microwave-absorbing heat-generating sheet 22, and a second microwave-absorbing heat-generating sheet 23. The coating layer 21 is applied to the bottom of the metal pan body 1. The first microwave-absorbing heat-generating sheet 22 is disposed on one side of the coating layer 21 away from the metal pan body 1. The second microwave-absorbing heat-generating sheet 23 is disposed on one side of the first microwave-absorbing heat-generating sheet 22 away from the coating layer 21. The coating layer 21, the first microwave-absorbing heat-generating sheet 22, and the second microwave-absorbing heat-generating sheet 23 are all capable of absorbing microwaves and generating heat. When this heating pot, which is commonly used in microwave ovens and ovens, is placed in a microwave oven and heated with microwaves, the coating layer 21, first microwave-absorbing heat-generating sheet 22, and second microwave-absorbing heat-generating sheet 23 absorb microwaves, generate heat, and transfer it to the metal pot body 1, thereby heating the food in the metal pot body 1. The heating pot, which is commonly used in microwave ovens and ovens according to the present invention, is equipped with a heat-generating composite layer, and the coating layer, first microwave-absorbing heat-generating sheet, and second microwave-absorbing heat-generating sheet of the heat-generating composite layer are all capable of absorbing microwaves and generating heat, thereby heating the food in the metal pot, and the food temperature rises quickly, reaching 170°C within 30 to 60 seconds. Furthermore, this heating box can also be used in ovens, making it versatile.

[0020] Specifically, when a heating pan commonly used in microwave ovens and ovens is placed in the oven to heat, the oven heats in three ways: radiant heat from an electric heating element, thermal conduction, and hot air convection, and the metal pan 1 is heated in these three ways when the oven is in operation. Because the metal pan 1 is made of metal and has excellent thermal conductivity, it can efficiently transfer heat to the food inside the metal pan 1, achieving the function of quickly heating the food. Therefore, the heating box is also applicable to oven heating.

[0021] Referring to Figures 1 to 4, the heat-generating composite layer 2 is installed under the metal pot body 1. The coating layer 21 is a microwave-absorbing paint. The microwave-absorbing paint is a conventional technology, and is selected from, for example, microwave-absorbing paints made by finishing resin and ceramic powder, or other paints that absorb microwaves and generate heat. The first microwave-absorbing heat-generating sheet 22 and the second microwave-absorbing heat-generating sheet 23 are both made of silica gel material, which absorbs microwaves and generates heat instantly, increasing their temperature. The melting points of the first microwave-absorbing heat-generating sheet 22 and the second microwave-absorbing heat-generating sheet 23 are 230°C to 250°C, providing excellent high-temperature resistance during heating, reducing melting and deformation, and ensuring a long service life. Because the maximum heating temperature of typical microwave ovens and ovens is below 230°C, selecting a silica gel material with a melting point of 230°C or higher allows for simultaneous use in both microwave ovens and ovens, thereby expanding the range of applications. Of course, for some special models of microwave ovens or ovens with a maximum temperature exceeding 230°C, silica gel materials with higher melting points, such as 240°C, 250°C or higher, may be selected.

[0022] Referring to Figures 3 and 4, the first microwave-absorbing heat-generating sheet 22 and the second microwave-absorbing heat-generating sheet 23 are bonded together using a polishing and compression process. During the polishing and compression process, high temperature and pressure are used to completely cross-link the silica gel molecular chains, resulting in a chemical bond at the interface between the first microwave-absorbing heat-generating sheet 22 and the second microwave-absorbing heat-generating sheet 23, without any physical adhesion. Therefore, the first microwave-absorbing heat-generating sheet 22 and the second microwave-absorbing heat-generating sheet 23 bonded together using the polishing and compression process are tighter, preventing the sheets from separating and becoming damaged. Furthermore, the polishing and compression process provides excellent high-temperature resistance, preventing separation even at high temperatures and ensuring a long service life. The first microwave-absorbing heat-generating sheet 22 is bonded to the coating layer 21 using a high-temperature-resistant adhesive. The high-temperature-resistant adhesive can withstand temperatures higher than the maximum heating temperature of a microwave oven or oven, preventing separation due to high temperatures, simplifying the process, and providing a robust structural connection.

[0023] Referring to Figures 1 to 4, the inner surface of the metal pot 1 is coated with a non-stick coating. The non-stick coating is a Teflon or ceramic coating that prevents food from sticking to the inner surface of the metal pot 1 during heating, facilitating food removal from the metal pot 1 and cleaning the metal pot 1 for a better user experience. A plurality of support protrusions 201 are installed under the heat-generating composite layer 2, which directly transfers heat generated by microwave heating to the bottom of the metal pot 1, enhancing the heat conduction effect, allowing the entire metal pot 1 to heat more quickly and heat food more effectively. The design of the support protrusions 201 creates a gap between the heat-generating composite layer 2 and the microwave oven or oven, promoting airflow and improving heating efficiency and uniformity. The contact between the support protrusions 201 and the microwave oven makes the metal pot 1 more sturdy and less likely to shake when heated or placed in place. Preferably, the entire outer bottom surface of the metal pot body 1 is covered with the heat generating composite layer 2, which ensures that heat is transferred evenly throughout the metal pot body 1, thereby ensuring uniform heating of the food inside the metal pot body 1 and increasing the heating effect.

[0024] Referring to Figures 1 and 6, the inner bottom of the metal pot 1 is provided with a plurality of protrusions 101, which reduce the contact area between the food and the inner bottom of the metal pot 1 and prevent the food from sticking to the inner bottom of the metal pot 1 during heating. The metal pot 1 is provided with a ring 3. The ring 3 is provided with a pouring groove 301 and a handle 302. The pouring groove 301 allows hot water from the metal pot 1 to be easily collected and dispensed. This prevents water from dripping into the surrounding environment when the hot water is dispensed, ensuring cleanliness and safety during operation. The two handles 302 are symmetrically positioned, allowing users to easily carry and move the heating box. The ring 3 and handle 302 are both made of dust-resistant silica gel material. The dust-resistant silica gel material is nano-hydrophobic coated silica gel or antistatic modified silica gel. The handle 302 is made of silica gel material to prevent burns. Furthermore, the use of silica gel material, which is dust-resistant, makes it difficult for dust to adhere to the surface of the handle 302, improving the cleanliness of the surfaces of the ring 3 and the handle 302.

[0025] Referring to Figures 1, 5, 6, and 10, the heating pot commonly used in microwave ovens and ovens further includes a lid 4. The lid 4 is detachably attached to the top of the metal pot 1. A positioning rib 401 is provided on the underside of the lid 4. A first positioning groove 303 is provided on the ring 3. When the lid 4 is placed in contact with the top of the ring 3, the positioning rib 401 is positioned within the first positioning groove 303. This facilitates keeping food warm within the metal pot 1 when the lid 4 is closed. Furthermore, the lid 4 is unlikely to slip or come off after being placed over the top of the metal pot 1, making it safe to use.

[0026] 6 to 11, the heating pot commonly used in microwave ovens and ovens further includes an intermediate box 5. The intermediate box 5 includes a metal plate 51 and an annular bracket 52 connected to the top of the metal plate 51. Two heat generating composite layers 2 are provided. One heat generating composite layer 2 is attached to the outer bottom of the metal pot body 1. The other heat generating composite layer 2 is attached to the outer bottom of the metal plate 51. A first abutting portion 521 is annularly attached to the underside of the annular bracket 52. A second abutting portion 304 corresponding to the first abutting portion 521 is attached to the upper side of the annular ring 3. A second positioning groove 522 corresponding to the positioning rib 401 is provided in the annular bracket 52. A groove inner wall 5221 is provided in the second positioning groove 522. A plurality of positioning regulating protrusions 4011 are attached to the outer wall of the positioning rib 401, which abut against the groove inner wall 5221 to regulate the position. When the intermediate box body 5 is placed in contact with the upper side of the ring 3, the first abutment portion 521 abuts against the second abutment portion 304. When the lid body 4 is placed in contact with the upper side of the annular bracket 52, the positioning rib 401 is positioned within the second positioning groove 522. As a result, when the lid body 4 is placed in contact with the upper side of the annular bracket 52, it is less likely to slip or come off, making it safe to use.

[0027] Furthermore, referring to Figures 1, 5, 7, 9, and 11, this heating pot commonly used in microwave ovens and ovens has the following three assembled states. 1. After placing food in the metal pot body 1, the lid body 4 is placed directly over the upper side of the ring 3, resulting in the first assembled state. In this case, the positioning rib 401 is positioned inside the first positioning groove 303. The heating box in this assembled state can be placed in a microwave oven or oven for heating. 2. After placing food in the metal plate 51 of the middle box body 5, the lid body 4 is placed directly over the upper side of the ring bracket 52, resulting in the second assembled state. The middle box body 5 in this assembled state is placed in a microwave oven or oven for heating. 3. When storing, the metal pot body 1, middle box body 5, and lid body 4 are folded sequentially from bottom to top, resulting in the third assembled state. In this case, the first contact portion 521 contacts the second contact portion 304, and the positioning rib 401 is positioned inside the first positioning groove 303, resulting in a compact structure, small space occupation, and easy storage. They can be used in combination as needed, and there are various usage forms.

[0028] The heating pot of the present invention, which is commonly used in microwave ovens and ovens, is equipped with a heat-generating composite layer. The coating layer of the heat-generating composite layer, the first microwave-absorbing heating sheet, and the second microwave-absorbing heating sheet all absorb microwaves and generate heat, thereby heating the food inside the metal pot and quickly raising the temperature of the food. Furthermore, the heating box is also suitable for oven heating, making it versatile. The first and second microwave-absorbing heating sheets are connected using a grinding and crimping process, which provides a tighter bond and prevents the two sheets from separating and becoming damaged. Furthermore, the grinding and crimping process provides excellent high-temperature resistance, making them less likely to separate even at high temperatures, and ensuring a long service life. The underside of the heat-generating composite layer is equipped with multiple support protrusions, which directly transfer the heat generated by microwave heating to the bottom of the metal pot, enhancing the thermal conduction effect, allowing the entire metal pot to heat up more quickly and more effectively. The support protrusions create a gap between the heat-generating composite layer and the microwave oven or oven, promoting airflow and improving heating efficiency and uniformity. The heating pot of the present invention, which is generally used in microwave ovens and ovens, has three combination states, making it more flexible to use.
