[0039] To make the technical problem to be solved, the technical solution and the beneficial effects of this utility model clearer, the following description is provided in conjunction with the appendix. Figures 1-6 The present invention will be further described in detail with reference to the embodiments.

[0040] Please refer to the following: Figures 1-3 In Embodiment 1 of this utility model, the micro-pressure three-dimensional heating container includes:

[0041] The insulated shell 1 has an opening 11 at its top and an inner cavity 12 on its inner side, the top of which communicates with the opening 11. A periphery 13 is provided at the opening 11 where the top of the insulated shell 1 communicates with the inner cavity 12. The heat-conducting pot body 3 has an opening 31 at its top and an inner cavity 32 on its inner side, the top of which communicates with the opening 31. A periphery 13 is provided around the opening 31 at the top of the heat-conducting pot body 3. The upper edge 33 of the body opening 31 is provided with an outwardly bent pot body periphery 34, and the lower side of the pot body periphery 34 is hung on the shell periphery 13 at the top of the heat-insulating shell 1; at least one heating element 2 is provided in the gap A between the inner cavity 12 of the shell and the heat-conducting pot body; the upper side of the pot body periphery 34 is provided with an inner container cover 4 and an outer container cover 5, and a cavity B located inside the pot body periphery 34 is left between the inner container cover 4 and the outer container cover 5, and a vent hole (not shown in the figure) is provided on the outer container cover 5.

[0042] Please refer to the following: Figures 1-3 In this embodiment, the micro-pressure three-dimensional heating container further includes:

[0043] A container shell 6 is sleeved on the outer side of the heat preservation shell 1, and a time controller 7 is arranged on the container shell 6 and electrically connected to the heating element 2. The container shell 6 simultaneously plays a heat insulation role, avoids rapid heat dissipation from the heat preservation shell 1, and prevents the user from directly holding the heat preservation shell 1 to cause inconvenience in taking and scalding.

[0044] In the embodiment, a heat insulation material layer (not shown in the figure) is arranged on the outer surface of the heat preservation shell 1 to realize heat preservation and insulation of the inner cavity 12 of the shell, and prevent heat from rapidly dissipating to the outside through the heat preservation shell 1.

[0045] As a preferred embodiment of the embodiment, the heat insulation material layer can be made of wood, heat-resistant plastic or the like.

[0046] In the embodiment, the heat-conducting pot body 3 is made of ceramic or metal.

[0047] As a preferred embodiment of the embodiment, the air vent is a micropore.

[0048] In the embodiment, the heating element 2 is a carbon fiber heating tube or a quartz heating tube.

[0049] In the preferred embodiment of the embodiment, the heating element 2 is a carbon fiber heating tube, and the heat radiation emitted by the carbon fiber heating tube is mainly in the form of far infrared radiation and is transmitted to the pot body through the inner cavity 12 of the shell. The carbon fiber heating tube has high electric heating conversion efficiency, good energy saving in water boiling, and low heat loss in heat transmission. Compared with a metal heating body, the light radiation of the carbon fiber heating tube is concentrated in the far infrared wave band between 1.5 μm and 15 μm, and the absorption wavelength and radiation intensity of organic matter such as carbohydrates are greatly improved. When the carbon fiber heating tube is used to irradiate cooking food, the cooking time of the food material can be greatly shortened due to the high infrared radiation intensity and strong permeability of the carbon fiber heating tube, and the taste of the food material can be kept as original as possible. In addition, the carbon fiber heating tube has the advantages of human affinity, health and environmental protection, and strong acid and corrosion resistance, thereby improving the adaptability of the heating container.

[0050] In an embodiment (not shown in the figure), a plurality of heating elements 2 are uniformly and spacedly arranged on the surface of the heating inner cavity, and each heating element 2 respectively radiates heat to the periphery of the heat-conducting pot body 3 in each direction corresponding to the inner cavity 12 of the shell, so as to further improve the heating uniformity and heating speed of the heat-conducting pot body 3.

[0051] Please refer to Figures 1-3 , as a preferred embodiment of the embodiment, the time controller 7 is integrally formed or embedded and detachably connected to the outer surface of the container cavity shell, and can be connected to the heating element 2 through a data line or in a wireless manner such as Bluetooth.

[0052] By setting the time controller 7, the user can edit the control heating time of the micro-pressure three-dimensional heating container, so as to realize the purpose of targeted timing cooking according to the heating needs of different food materials. Through actual test, the micro-pressure three-dimensional heating container provided by the utility model can complete the cooking of rice within 8-10 minutes, which is faster than the traditional electric rice cooker, and has certain cooking effect similar to the cooking effect of the wood fire stove. The micro-pressure three-dimensional heating container provided by the utility model can also perform the operation of boiling soup or other heat preservation cooking.

[0053] In addition, since the cooking process can be quickly completed, the micro-pressure three-dimensional heating container is not provided with a temperature sensor, and only needs to be provided with the time controller 7 to control the heating time, so as to reduce the manufacturing and use cost of the heating container.

[0054] Please refer to Figures 1-3 In an embodiment of the embodiment, the pot periphery 34 comprises:

[0055] The first annular bending part 341 is arranged on the top of the heat-conducting pot 3 around the upper edge 33 of the pot opening 31 and is arranged in a circumferential direction of the heat-conducting pot 3. The lower surface of the first annular bending part 341 constitutes the lower side of the pot periphery 34. The support ring 342 is arranged on the top edge of the first annular bending part 341 and is arranged in a circumferential direction of the heat-conducting pot 3. The inner side wall of the support ring 342 and the first annular bending part 341 form a first step 343 in the shape of a ring. The top end surface of the support ring 342 and the bottom surface of the first step 343 constitute the upper side of the pot periphery 34.

[0056] The bottom end of the container inner cover 4 is provided with a second step 41 matched with the first step 343. The outer diameter of the container inner cover 4 is matched with the size of the projection area of the first step 343 in the axial direction of the heat-conducting pot 3. The bottom of the container outer cover 5 is provided with an outer cover opening 51. The inner side of the container outer cover 5 is provided with an outer cover inner cavity 52 which is in communication with the outer cover opening 51 at the bottom end. The inner diameter of the bottom of the container outer cover 5 around the lower edge 53 of the outer cover opening 51 is larger than the inner diameter of the support ring 342, as shown in Figures 1-3 .

[0057] As shown in Figures 1-3 , when the micro-pressure three-dimensional heating container is used, the heat-conducting pot 3 is hung on and supported by the shell periphery 13 at the top end of the heat preservation shell 1 through the bottom surface of the first annular bending part 341 (that is, the lower side of the pot periphery 34), that is, the bottom surface of the first annular bending part 341 is supported on the upper surface of the shell periphery 13. At the same time, the heat-conducting pot 3 completely covers and closes the shell inner cavity 12 with the first annular bending part 341, and the gap A between the heat-conducting pot 3 and the shell inner cavity 12 of the heat preservation shell 1 forms a semi-enclosure around the heat-conducting pot 3.

[0058] The time slot A is used as a closed heating air gap. The heating element 2 arranged in the gap A radiates heat to the air in the gap A, which is semi-enclosed around the heat-conducting pot body 3 and the bottom, so that the air in the gap A conducts heat to all directions of the pot body, achieving multi-directional and three-dimensional heating of the heat-conducting pot body 3. That is, the heat-conducting pot body 3 can be heated in the direction of 180 degrees (i.e. half sphere) below the opening 31 of the heat-conducting pot body 3 and the side of the heat-conducting pot body 3 by the heat radiation of the heating element 2, improving the uniformity of the heat in all directions of the heat-conducting pot body 3 and the heating speed of the micro-pressure three-dimensional heating container.

[0059] Please refer to Figures 1-3 , as the preferred embodiment of the present embodiment, the inner side wall of the top end of the support ring 342 is provided with a third step 3421 in the form of a ring, and the inner diameter of the lower edge 53 matches the size of the third step 3421. The top surface of the support ring 342, the third step 3421 and the bottom surface of the first step 343 constitute the upper surface of the above-mentioned pot body periphery 34. When the micro-pressure three-dimensional heating container is in use, the surface of the lower edge 53 of the container outer cover 5 is supported on the third step 3421 of the inner side wall of the top end of the support ring 342, so that the container outer cover 5 covers and seals the inner space of the support ring 342, thereby maintaining the micro-pressure state of the pot body cavity 32 through the air-tight sealing effect of the inner and outer layers of the container inner cover 4 and the container outer cover 5 when the heat-conducting pot body 3 is heated, so as to accelerate the cooking process of the food contained in the pot body cavity 32.

[0060] At the same time, due to the air vent on the container outer cover 5, when the pressure in the pot body cavity 32 is relatively large and the container inner cover 4 is lifted, the excess gas leaked into the cavity B between the container inner cover 4 and the container outer cover 5 can be discharged from the micro-pressure three-dimensional heating container through the air vent, preventing the gas from escaping from the third step 3421 and causing foam at that location.

[0061] Please refer to Figures 1-3 , as the preferred embodiment of the present embodiment, at least one handle 9 is arranged on the side of the first annular bending part 341.

[0062] Please refer to Figures 1-3 , as the more preferred embodiment of the present embodiment, a pair of handles 9 are symmetrically arranged on opposite sides of the first annular bending part 341.

[0063] Please refer to Figures 1-3 , as the other embodiment of the present embodiment, only one handle 9 can be arranged on the side of the first annular bending part 341, or three or more handles can be uniformly and spacedly arranged on the side of the first annular bending part 341 along the circumference of the micro-pressure three-dimensional heating container.

[0064] Please refer to Figures 1-3In the embodiment, the container outer cover 5 and the container inner cover 4 are provided with handles 8 at the top ends, so that the user can hold and place the container outer cover 5 and the container inner cover 4.

[0065] Please refer to Figures 1-3 In the embodiment, the container shell 6 is cylindrical, and the heat-insulating shell 1 and the heat-conducting pot body 3 are both egg-shaped, with the outer diameter gradually shrinking from the top to the bottom.

[0066] Please refer to Figures 4-6 In the embodiment, the container outer cover 5 is dome-shaped, and the inner cavity 52 of the container outer cover 5 is dome-shaped, with the top narrow and the bottom wide.

[0067] In the embodiment, the wall thickness of the heat-conducting pot body 3 is 5-14 mm.

[0068] As an implementation of the embodiment, the wall thickness of the heat-conducting pot body 3 is 5 mm. Since the outer surface of the heat-insulating shell 1 is provided with a layer of heat insulation material, the heat-insulating effect of the inner cavity 12 of the shell is improved, so that the wall thickness of the heat-conducting pot body 3 can be appropriately thinned under the condition that the heat-conducting pot body 3 does not need to have too high heat storage capacity.

[0069] As another implementation of the embodiment, the wall thickness of the heat-conducting pot body 3 is 12 mm. Since the wall thickness of the heat-conducting pot body 3 is thickened, the heat storage capacity of the heat-conducting pot body 3 is improved, so that after the heating element 2 is powered off (i.e., the micro-pressure three-dimensional heating container is extinguished), the food can be simmered by the residual heat of the heat-conducting pot body 3, so that the cooking is completed within 10 minutes.

[0070] Please refer to ​ In the second embodiment of the utility model, the micro-pressure three-dimensional heating container is different from the first embodiment in that:

[0071] The top end of the support ring 342 is provided with a second annular bending part 344, the inner diameter dimension of the bottom of the outer cover opening 51 around the lower part of the outer cover opening 51 is larger than the inner diameter dimension of the support ring 342, and matches the size of the second annular bending part 344. The top end surface of the support ring 342, the top end of the second annular bending part 344, and the bottom surface of the first step 343 constitute the upper side of the pot body periphery 34.

[0072] The container inner cover 4 is supported at the first step 343 by the second step 41, so that the container inner cover 4 covers and seals the inner cavity 32 of the inner side of the heat-conducting pot 3, and the lower edge surface 53 of the container outer cover 5 is supported at the top end of the support ring 342 and the top end of the second annular bending part 344 connected to the support ring 342, so that the container outer cover 5 covers and seals the inner side space of the support ring 342, thereby keeping the inner cavity 32 in a micro-pressure state when the heat-conducting pot 3 is heated, so as to accelerate the cooking process of the food materials contained in the inner cavity 32.

[0073] Please refer to 4-6, in the preferred embodiment of the present embodiment, the top end of the second annular bending part 344 is provided with a flange 345 which circumferentially surrounds the heat-conducting pot 3, and a fourth step 346 is formed between the flange 345 and the second annular bending part 344.

[0074] The lower edge surface 53 of the container outer cover 5 is supported at the top end of the second annular bending part 344, and the relative sliding and displacement of the container outer cover 5 along the top surface of the second annular bending part 344 is limited by the flange 345, so as to improve the support stability of the container outer cover 5 during heating.

[0075] In other embodiments (not shown in the drawings), the micro-pressure three-dimensional heating container further comprises:

[0076] The control device is arranged on the container shell 6 and electrically connected to the heating element 2, and the temperature detector is arranged in the gap A between the inner cavity 12 of the shell and the heat-conducting pot or on the heat-insulating shell 1 and electrically connected to the control device.

[0077] The temperature detector is used to detect the temperature of the gap A in the inner cavity 12 of the shell or the heat-insulating shell 1 in real time, so as to indirectly detect the temperature of the heat-conducting pot 3, for example, when the temperature of the gap A in the inner cavity 12 of the shell or the heat-insulating shell 1 reaches 400 degrees, it is estimated that the temperature of the heat-conducting pot 3 can reach 300 degrees. The control device is used to set a preset temperature corresponding to the food materials, and when the temperature detector detects that the temperature of the gap A in the inner cavity 12 of the shell or the heat-insulating shell 1 reaches a target temperature matching the preset temperature, the control device feeds back to control the heating element 2 to be powered off so as to stop heating the food materials.

[0078] As a preferred embodiment, the control device can be a control panel, a control mainboard or the like.

[0079] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. It should be understood by those skilled in the art that any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
