Description

Technical Field

[0001] This invention relates to the field of kitchenware technology, specifically to a deformation isolation component and a non-pressure cooking kitchenware. Background Technology

[0002] Among household kitchen appliances, the main products with non-pressure cooking technology currently include vacuum cookers, slow cookers, and pressure cookers.

[0003] The advantage of vacuum cookers is that they allow the food's microstructure to expand under low pressure, making it easier for the food to absorb flavor. However, because the heating medium (water) has a lower boiling point under low pressure, the food takes longer to cook completely.

[0004] Among them, the advantage of slow cookers is that they can be used with sealing bags to vacuum seal food, preventing food juices from leaking into the heating medium. The disadvantages are that the cooking temperature is low, which may result in undercooked food, and the sealing measures are separate from the cookware, which makes them less convenient.

[0005] Among them, the advantage of pressure cookers is that they can improve cooking efficiency by raising the boiling point of the heating medium, but the disadvantage is that they are more destructive to the nutrients in food, and nutrients are easily lost. Summary of the Invention

[0006] The primary objective of this invention is to provide a deformation-insulating component for use in non-pressure cooking appliances, which can create high-pressure and low-pressure zones for non-pressure cooking appliances, enabling food to be cooked under high pressure in a low-pressure environment, thereby preserving the nutritional components of the food and improving cooking efficiency.

[0007] The second objective of this invention is to provide a non-pressure cooking appliance that can cook food under high pressure in a low-pressure environment, thereby preserving the nutritional components of the food and improving cooking efficiency.

[0008] The first objective of the present invention is to provide a deformation isolation member comprising opposing first and second sides separated therefrom; the deformation isolation member includes a deformation container disposed on the first side, the deformation container having an opening disposed toward the second side, and the deformation container being able to change between a contracted state and an expanded state under pressure difference changes between the second side and the first side.

[0009] As can be seen from the above scheme, placing the deformation-insulating component in the non-pressure cooking appliance creates a first pressure zone and a second pressure zone on opposite sides of the component. The first pressure zone is used as the heating medium, and the second pressure zone includes the containment space of the deformation container. With a pressure regulating device such as a pressure regulating pump, after the pump is turned on, air is first drawn from the first pressure zone, causing the deformation container to gradually open as the pressure in the first pressure zone decreases. When the pressure in the first pressure zone drops to a certain value, the pressure regulating pump stops operating, at which point the food can be completely placed into the deformation container. After sealing the non-pressure cooking appliance, the pressure regulating pump then draws air from the second pressure zone into the first pressure zone. At this point, the first pressure zone becomes a high-pressure zone, and the second pressure zone becomes a low-pressure zone. The deformation container then gradually contracts with the pressure difference, sealing the food inside. The high-boiling-point heating medium in the high-pressure zone cooks the food at a higher temperature than at normal pressure. The food's microstructure expands under low pressure, resulting in better flavor absorption, effectively improving heating efficiency and enhancing food quality.

[0010] A further option is that the deformation isolation component has plastic deformation capability; and / or, the deformation isolation component has elastic deformation capability.

[0011] A further proposed solution is to use a flexible material to make the deformation container and to design the deformation container as a bag structure; or, to design the deformation isolation component to have plastic deformation capability and to design the deformation container as a foldable structure.

[0012] As can be seen from the above, for example, deformable containers with plastic deformation capabilities can be configured as bag structures or folded structures, while deformable containers with elastic deformation capabilities can be configured as expansion structures. Both methods can achieve the change of the deformable container from a contracted state to an expanded state. Preferably, folded structures are beneficial for increasing the volume of the deformable container; preferably, when configured as a bag structure, the opening of the deformable container is squeezed and self-closed under pressure difference to form a sealed and stable food space.

[0013] A further approach is that, under the pressure difference between the second and first sides, the deformation container can close the opening.

[0014] As can be seen above, unlike traditional cooking utensils that transfer heat through air or steam, the deformable container, being a closed space, heats food by pressing it tightly against the inner wall, effectively improving heating efficiency and solving the problem of undercooked food in traditional low-pressure cookers. Furthermore, because the food's nutrients do not directly contact the heating medium, they remain within the food and its juices throughout the heating process, further enhancing food quality.

[0015] A further option is to include at least one of the following: the deformation isolation component is made of a high-temperature resistant material; the deformation isolation component is made of a high-pressure resistant material; or the deformation isolation component is made of a food-grade material.

[0016] As can be seen from the above, this setup can meet the requirements of the deformation insulation component not only to withstand high temperatures, but also to withstand high pressure from the high-pressure zone and to come into contact with food.

[0017] A further embodiment is that the deformation isolation component includes a flattened portion; the deformation container bends out from the flattened portion; and a sealing mating portion is provided on the outer peripheral edge of the flattened portion.

[0018] As can be seen from the above, in this configuration, the flat section is used to divide the space and to seal with other components of the kitchenware.

[0019] The second objective of this invention is to provide an unpressured cooking appliance that includes the aforementioned deformation isolation member and pressure regulating device; a first pressure zone and a second pressure zone are formed within the unpressured cooking appliance by being isolated by the deformation isolation member, the first pressure zone is connected to a first side, the second pressure zone is connected to a second side, and the accommodating space of the deformation container is located in the second pressure zone; the pressure regulating device is used to adjust the pressure of the first pressure zone and the pressure of the second pressure zone.

[0020] As can be seen from the above scheme, the first pressure zone is used as the heating medium, and the second pressure zone includes the containment space of the deformable container. With a pressure regulating device such as a pressure regulating pump, after the pump is turned on, air is first drawn from the first pressure zone, and the deformable container gradually opens as the pressure in the first pressure zone decreases. When the pressure in the first pressure zone drops to a certain value, the pressure regulating pump stops operating, at which point the food can be completely placed into the deformable container. After sealing the non-pressure cooking appliance, the pressure regulating pump then draws air from the second pressure zone into the first pressure zone. At this point, the first pressure zone becomes a high-pressure zone and the second pressure zone becomes a low-pressure zone. The deformable container then gradually contracts with the pressure difference, sealing the food inside. The high-boiling-point heating medium in the high-pressure zone cooks the food at a higher temperature than at normal pressure. The food's microstructure expands under low pressure, resulting in better flavor absorption, effectively improving heating efficiency and enhancing food quality.

[0021] A further option is that the non-pressure cooking appliance includes a limiting member, which restricts the deformation of the insulating member from the second side.

[0022] As can be seen from the above, the setting of the limiting component can effectively prevent the deformation isolation component from being lifted when the high pressure zone is pressurized, and avoid causing food to not be sealed properly and the lid to become dirty.

[0023] A further solution is that the non-pressure cooking appliance includes a main container and a connecting seat; the main container includes a peripheral wall, the connecting seat is connected to the peripheral wall, a deformation isolation component is disposed between the peripheral wall and the connecting seat, and a pressure regulating device is connected to the connecting seat; a first pressure zone is formed between the main container and the deformation isolation component.

[0024] As can be seen from the above, the connection seat enables the installation of deformation isolation components and pressure regulating devices.

[0025] A further solution is that the non-pressure cooking appliance includes a lid that is detachably or movably connected to a connecting seat; a second pressure zone is formed between the lid and the deformation isolation component.

[0026] As can be seen from the above, the connector is also used to connect with the cover, completing the connection and fixation of multiple components with one component, reducing the number of product components, and simplifying and making the product structure more reliable.

[0027] A further embodiment includes at least one of the following: a first seal is provided between the deformation isolator and the connecting seat; a second seal is provided between the connecting seat and the cover; and a third seal is provided between the deformation isolator and the peripheral wall.

[0028] As can be seen from the above, this setting can ensure a seal at each connection point as much as possible.

[0029] A further design includes an air inlet, an air outlet, and an interface on the pressure regulating device, and an air valve on the deformation isolation component. In the first mode of the pressure regulating device, the first pressure zone, the air valve, the air outlet, and the second pressure zone are connected in sequence. In the second mode of the pressure regulating device, the second pressure zone, the air inlet, the air valve, and the first pressure zone are connected in sequence.

[0030] As can be seen from the above, under this setting, the first mode can depressurize the first pressure zone, allowing the deformable container to open and food to be placed inside. The second mode can increase the pressure of the first pressure zone and depressurize the second pressure zone, thus making the first pressure zone a high-pressure zone and the second pressure zone a low-pressure zone.

[0042] First embodiment of non-pressure cooking appliance

[0043] See Figure 1 and Figure 2 The non-pressure cooking appliance in this embodiment is a cooking pot, which includes a pot body 1, the deformation isolation component 2 of the present invention, a pressure regulating pump 3, a pot lid 4, a limiting component 5, a connecting seat 6, a first sealing ring 71 and a second sealing ring 72. The pot body 1, the pressure regulating pump 3, the pot lid 4, the first sealing ring 71 and the second sealing ring 72 are respectively the main container, the pressure regulating device, the cover, the first sealing component and the second sealing component of the present invention.

[0044] The pot body 1 has a peripheral wall 11, the inner periphery of the peripheral wall 11 forms the interior 10 of the pot body 1, the interior 10 is open at the upper end of the pot body 1, and a protective edge 12 is provided at the top of the peripheral wall 11, the inner periphery of the protective edge 12 forms a step position 120 for installing support.

[0045] A raised edge 211 around the outer periphery of the deformation isolator 2 is supported on the step 120, while the deformation isolator 2 is located inside the 10. The raised edge 211 is the sealing mating part of the present invention.

[0046] The connecting seat 6 and the first sealing ring 71 are annular, while the second sealing ring 72 has a notch and is not a complete annulus. The convex edge 211, the first sealing ring 71, the connecting seat 6, the second sealing ring 72, and the pot lid 4 are sequentially and sealingly connected. The limiting member 5 is installed on the inner circumference of the connecting seat 6 and is located directly above the deformation isolator 2. The pressure regulating pump 3 is fixedly connected to the upper side of the connecting seat 6 and is located at the notch of the second sealing ring 72. The first sealing ring 71 is fixed to the lower side of the connecting seat 6, and the second sealing ring 72 is fixed to the lower side of the pot lid 4. A first pressure zone 101 and a second pressure zone 102 are formed inside the non-pressure cooking appliance by being isolated by the deformation isolator 2. The first pressure zone 101 is formed between the pot body 1 and the deformation isolator 2, and the second pressure zone 102 is formed between the pot lid 4 and the deformation isolator 2. The pressure regulating pump 3 is located between the first pressure zone 101 and the second pressure zone 102. The pot lid 4 can be detachably connected to the connecting seat 6 as a whole, or it can be movably connected to the connecting seat 6 in the form of a flip-top lid.

[0047] See Figure 1 and Figure 3 The deformable barrier 2 is made of a plastic material. Specifically, the deformable barrier 2 has flexible deformation capability, and its flexible deformation effect is similar to that of a sealed bag. In addition, the deformable barrier 2 is made of a food-grade material that is resistant to high temperature and high pressure. The deformable barrier 2 includes a flat part 21 and a deformable container 22. The flat part 21 is circular, and its outer peripheral edge is provided with the aforementioned protruding edge 211. The protruding edge 211 is made of a rigid material, and the outer peripheral edge of the flat part 21 is supported by the protruding edge 211. A straight opening 2201 is provided in the center of the flat part 21. This opening 2201 is the entrance of the deformable container 22. The inner peripheral part of the flat part 21 gradually bends downward towards the opening 2201 until it hangs down to form the deformable container 22. The deformable isolator 2 includes opposing first side 201 and second side 202 separated therefrom, and deformable container 22 bends out from the edge of opening 2201 toward first side 201, deformable container 22 is located on first side 201, while opening 2201 faces second side 202.

[0048] like Figure 1 As shown, when the deformation isolator 2 is installed inside the cooking pot, the first side 201 is connected to the first pressure zone 101, and the second side 202 is connected to the second pressure zone 102. It should also be noted that although the deformation container 22 is located on the second side 202, its accommodating space 220 is actually connected to the first pressure zone 101 through the opening 2201; therefore, the accommodating space 220 is part of the first pressure zone 101. Furthermore, a valve 23 and a sensor 24 are installed on the flat part 21 near the protruding edge 211. The valve 23 is a bidirectional valve, and the sensor 24 is used to detect the pressure in the first pressure zone 101.

[0049] See Figure 1 and Figure 4 The air pressure regulating pump 3 is equipped with an air inlet 32, an air outlet 31, an interface 33, a sensor interface 34, and a pressure relief valve 35. Combined with... Figure 6 and Figure 7 , Figure 6 In the first mode of the pressure regulating pump 3 shown, the first pressure zone 101, the air valve 23, the air outlet 31, and the second pressure zone 102 are connected in sequence. Figure 7 In the second mode of the pressure regulating pump 3 shown, the second pressure zone 102, air inlet 32, air valve 23, and first pressure zone 101 are sequentially connected. Additionally, sensor interface 34 interfaces with sensor 24 to obtain pressure data of the first pressure zone 101. When the pressure data of the first pressure zone 101 exceeds a preset value, pressure relief valve 35 is activated to relieve pressure in the first pressure zone 101. See also... Figure 4 In this embodiment, the lower side of the connecting seat 6 is provided with an annular first groove 601, and the first sealing ring 71 is fixedly installed in the first groove 601.

[0050] See Figure 1 and Figure 5 The limiting member 5 is used to restrict the deformation isolator 2 from the second side 202. In this embodiment, the second side 202 is above the deformation isolator 2. The limiting member 5 can press the deformation isolator 2 downward from above to prevent the deformation isolator 2 from deforming upward under high pressure. In this embodiment, the limiting member 5 includes an outer ring 51 with a notch on its outer periphery and a grid 52 connecting different positions on the inner side of the outer ring 51. In this embodiment, the grid 52 includes two first beams extending along a first direction and one second beam extending along a second direction. The first direction and the second direction are perpendicular to each other. The first beam and the second beam intersect and are connected. The extended ends of the first beam and the second beam are both connected to the inner side of the outer ring 51. In this configuration, the mesh 52 not only enhances the strength of the limiting member 5, but also serves as the main functional part of the deformation-limiting isolator 2. Furthermore, mesh openings 50 are formed between the meshes 52, directly opposite the opening 2201 of the deformation-limiting isolator 2. Under certain circumstances, food can be fed into the deformation container 22 through the mesh openings 50 and the opening 2201 without disassembling the limiting member 5. Additionally, a notch 59 is formed on the limiting member 5 to cooperate with the pressure regulating pump 3.

[0051] The first pressure zone 101 contains a heating medium, such as water. (Comparison) Figure 1 and Figure 6When the pressure regulating pump 3 is in the first mode, the first pressure zone 101, the air valve 23, the air outlet 31, and the second pressure zone 102 are connected in sequence, drawing gas from the first pressure zone 101 to the second pressure zone 102. Generally, during this process, the pot lid 4 is opened and the limiting part 5 is removed. The second pressure zone 101 is connected to the outside while the first pressure zone 101 is a closed structure. During this process, the air pressure in the first pressure zone 101 continuously decreases. At this time, the air pressure in the first pressure zone 101 is lower than the pressure difference in the second pressure zone 102. Under the action of the pressure difference between the first pressure zone 101 and the second pressure zone 102, the deformable container 22 changes from a contracted state where its two side walls 221 are tightly attached to its contracted state to an expanded state where it is open to the two side walls 221 and forms a larger accommodating space 220. Then, the food 9 can be put into the deformable container 22 through the opening 2201.

[0052] See Figure 7 When the ingredients 9 are added and the limiting parts 5 and the pot lid 4 are installed, the pressure regulating pump 3 is controlled to operate in the second mode. The second pressure zone 102, the air inlet 32, the air valve 23 and the first pressure zone 101 are connected in sequence. The gas in the second pressure zone 102 is drawn and transported to the first pressure zone 101. Since the first pressure zone 101 and the second pressure zone 102 are both closed structures at this time, the first pressure zone 101 is continuously pressurized and the second pressure zone 102 is continuously depressurized during the process, so that the first pressure zone 101 becomes a high pressure zone and the second pressure zone 102 becomes a low pressure zone. The heating medium is in the high pressure zone and the ingredients 9 are in the low pressure zone.

[0053] Therefore, the high-boiling-point heating medium in the high-pressure zone will cook food at a higher temperature than that under normal pressure. The food's microstructure expands under low pressure, making it more flavorful, effectively improving heating efficiency and enhancing food quality.

[0054] In addition, the high pressure of the second pressure zone 101 at this time causes the tops of the two side walls 221 to stick together tightly and seal the entrance 2201, making the containing space 220 a sealed space. The two side walls squeeze the food 9 so that the food 9 sticks tightly to the side walls 221, which can achieve a better heating effect. The limiting member 5 can press the deformation isolation member 2 under the limiting member 5 to ensure the sealing effect and the food sticks tightly to the deformation container 22.

[0055] Second embodiment of non-pressure cooking appliance

[0056] See Figures 8 to 11 , Figure 8 and Figure 10 These are views from two mutually perpendicular perspectives of the same state. Figure 9 and Figure 11 This is a view from two mutually perpendicular perspectives of another state.

[0057] In this embodiment, the deformation insulating member is made of a plastic material. More specifically, the deformation container 81 in this embodiment is configured as a foldable structure, and the contracted state of the deformation container 81 is the folded state. Figure 8 and Figure 10 The folded form of the deformable container 81 is shown. Figure 9 and Figure 11 The expanded state of the deformable container 81 is shown.

[0058] In other embodiments, the deformation isolation element is made of an elastic material, and the deformation container is configured as an expandable structure.

[0059] Finally, it should be emphasized that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
