Description

Technical Field

[0001] This utility model relates to the field of microwave ovens, specifically a cooking utensil based on microwave heating. Background Technology

[0002] Microwave ovens are a common cooking appliance found in almost every household. Their working principle is as follows: microwaves generated by a microwave generator create a microwave electric field within the microwave oven cavity. When food is placed in this field, the microwaves radiate onto it. Food always contains a certain amount of water, and water is composed of polar molecules (molecules whose positive and negative charge centers do not coincide even in the absence of an external electric field). The orientation of these polar molecules changes with the microwave field. Due to this movement of the water's polar molecules within the food, and the interaction between adjacent molecules, a friction-like phenomenon occurs, causing the water temperature to rise. Consequently, the temperature of the food also rises, ultimately achieving the effect of cooking the food. However, the temperature at which food is heated in a microwave oven is usually related to the heating time, the type of food, and the quantity of food. Generally, the highest temperature reached is only about 100°C, and it may only reach about 250°C at an instant. This temperature is not suitable for cooking various foods, such as pizza and roasted sweet potatoes. Pizza or roasted sweet potatoes often require an environment of 400-500°C to achieve high-quality production. In order to meet the needs of some foods for high-temperature cooking environment, it is necessary to design a cooking utensil suitable for microwave ovens. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a microwave-heated cooking vessel that can generate high temperatures under microwave excitation to meet the cooking requirements of food.

[0004] The purpose of this utility model is achieved as follows:

[0005] A microwave-heated cooking utensil includes a plate and a lid, with the lid covering the plate to form a closed heating cavity. The plate and / or the lid are provided with an absorbing layer for absorbing microwave heat, and the absorbing layer is located outside the heating cavity.

[0006] As a specific solution, a heat insulation layer is provided on the outside of the absorbing layer to block the transmission of heat.

[0007] As another specific solution, a surface layer is provided on the outside of the insulation layer.

[0008] As another specific solution, a food-grade inner wall is provided on the heating cavity, which is located on the plate and / or cover, and the food-grade inner wall is located inside the microwave absorbing layer.

[0009] As another specific solution, the disc and the cover are connected movably; or, the disc and the cover are set separately.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] First embodiment:

[0022] See Figures 1-3This embodiment relates to a microwave-heated cooking vessel, including a plate body 1 and a lid body 2. The lid body 2 covers the top of the plate body 1, forming a closed heating cavity 3, in which food is placed. To greatly improve heating efficiency, both the plate body 1 and the lid body 2 are provided with microwave-absorbing layers 6 for absorbing microwave heat. The microwave-absorbing layers 6 are located outside the heating cavity 3. Of course, depending on actual needs, the microwave-absorbing layer 6 can be provided separately in the plate body 1 or the lid body 2. Specifically, the microwave-absorbing layer 6 is made of microwave-absorbing heat-generating material, enabling it to absorb microwaves (such as electromagnetic waves) and convert them into heat energy. Heating materials can be classified according to their elements, such as carbon-based microwave absorbing materials, iron-based microwave absorbing materials, and ceramic-based microwave absorbing materials. That is, the material used to prepare the microwave absorbing layer 6 is ceramic, quartz glass, graphite, etc. When this cooking vessel is placed in a microwave electric field, the microwave absorbing layer 6 acts as a heating element, which heats up rapidly under the action of microwaves, and the temperature rise effect is high, so that the heating cavity 3 is in an ultra-high temperature environment, which can effectively heat the food and achieve the cooking effect. The temperature inside the heating cavity 3 can reach 400-500℃ or even higher, which can meet the needs of making pizza, roasted sweet potatoes, etc., expand the function of microwave ovens, and meet more cooking requirements of users.

[0023] Furthermore, an insulation layer 5 is provided on the outer side of the absorbing layer 6 to block the transmission of heat; the insulation layer 5 effectively blocks the transmission of heat; on the one hand, it can effectively lock the heat in the heating cavity 3 and prevent the heat from being lost outward; on the other hand, it prevents the heat from being transmitted to the surface of the cooking utensils, causing the surface temperature to be too high, avoiding burn accidents and improving the safety factor.

[0024] Furthermore, a surface layer 4 is provided on the outside of the heat insulation layer 5. The surface layer 4 is preferably made of a material with high plasticity and high temperature resistance. The shape of the cooking vessel can be better designed through the surface layer 4. Since most of the heat has been blocked by the heat insulation layer 5, less heat reaches the surface layer 4, which can prevent the surface temperature of the cooking vessel from becoming too high.

[0025] Furthermore, a food-grade inner wall 7 is provided on the outer side of the heating cavity 3. The food-grade inner wall 7 is preferably made of food-grade material, so that the inner wall of the heating cavity 3 can come into contact with food to ensure food safety. The food-grade inner wall 7 is respectively provided on the plate body 1 and the cover body 2, and the food-grade inner wall 7 is located inside the microwave absorbing layer 6. According to actual needs, the food-grade inner wall 7 can be provided on the plate body 1 or the cover body 2 alone. When the microwave absorbing layer 6 is made of food-grade material, the food-grade inner wall 7 can be directly the inner wall of the microwave absorbing layer 6.

[0026] Furthermore, in this embodiment, the disc 1 and the cover 2 are movably connected; specifically, one side of the disc 1 and one side of the cover 2 are hinged to each other, and the cover 2 can be flipped relative to the disc 1. The heating chamber 3 can be opened or closed by flipping the cover 2, which is convenient and simple to operate. In addition, the disc 1 and the cover 2 can also be set separately according to actual needs.

[0027] Furthermore, in this embodiment, the plate body 1 and the lid body 2 are respectively provided with handles 8. The handles 8 on the plate body 1 can be provided on both sides, so that the user can lift the cooking utensils by the handles 8 on both sides. The handles 8 on the lid body 2 can be provided on the top or side, so that the user can open and close the lid by the handles 8. Depending on the actual needs, the handles 8 can be provided on the plate body 1 or the lid body 2 alone.

[0028] Furthermore, the plate body 1 includes a flat bottom plate 101 and one or more lower side plates 102. The lower side plate 102 is vertically disposed at the top edge of the bottom plate 101. The one or more lower side plates 102 surround the outside of the heating cavity 3 and form an upper opening 103 at the top. Food can be placed into the heating cavity 3 through the upper opening 103. The cover body 2 covers the upper opening 103, thereby effectively sealing the top of the heating cavity 3. In this embodiment, the bottom plate 101 and the lower side plate 102 are respectively provided with a wave-absorbing layer 6, that is, both the bottom plate 101 and the lower side plate 103 can generate heat and spread it into the heating cavity 3. By releasing heat from multiple directions, the heating efficiency is effectively improved and an ultra-high temperature cooking environment is guaranteed. According to actual needs, the bottom plate 101 or the lower side plate 103 can be provided with a wave-absorbing layer 6 separately.

[0029] Furthermore, an open side wall is formed by the upper and lower side plates 102, and the opening of the side wall constitutes a side opening 104 that connects to the heating chamber 3. The cover 2 at least partially covers the side opening 104. By setting the side opening 104 to connect to the side wall of the heating chamber 6, the user can put the food into the heating chamber 3 through the side opening 104. This is generally suitable for making pizza. Flat and soft pizzas are most suitable to be put in and taken out through the side opening 104 to avoid damaging the pizza 104.

[0030] Furthermore, the cover 2 includes a top plate 201 and one or more upper side plates 202. The upper side plates 202 are vertically disposed at the bottom edge of the top plate 201. The top plate 201 covers the upper opening 103, and the one or more upper side plates 202 cover the side opening 104. In this embodiment, the top plate 201 and the upper side plates 202 are respectively provided with a wave-absorbing layer 6. Similarly, the number of heat release positions can be increased to further improve the heating efficiency. According to actual needs, the top plate 201 or the upper side plate 202 can be provided with a wave-absorbing layer 6 separately.

[0031] Second embodiment:

[0032] See Figure 4 The difference between this embodiment and the first embodiment is that the disc body 1 and the cover body 2 are set separately; the cover body 2 in this embodiment does not have a wave-absorbing layer 6 and is made of a single material, such as glass, ceramic, metal, etc.

[0033] The other undescribed parts are basically the same as those in the first embodiment, and will not be analyzed or explained in detail here.
