Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and particularly relates to a pressure cooking appliance. Background Art

[0002] In existing cooking appliances (such as rice cookers, electric pressure cookers, etc.), partition components such as steamers are often equipped. During cooking, users can place the steamer inside the inner pot according to needs, so that the steamer divides the inner part of the inner pot into upper and lower cavities, and thus ingredients can be placed in the upper and lower cavities respectively, and the cooking of two kinds of foods can be completed simultaneously in one cooking.

[0003] According to different models, the placement position of the steamer inside the inner pot is also different. For normal pressure cooking appliances such as rice cookers, the steamer usually leans on the flanging of the inner pot mouth edge. For pressure cooking appliances, in order to ensure normal pressure build-up inside the inner pot so as to reliably perform pressure cooking, it is necessary to ensure the sealing performance between the pot lid sealing ring and the flanging of the inner pot mouth edge. Therefore, if the steamer leans on the inner pot flanging, the steamer will interfere with the pot lid sealing ring, resulting in a poor state of the sealing ring, and further affecting the sealing performance.

[0004] Moreover, the processing technology of the inner pot usually forms a inwardly concave necking structure at the neck of the inner pot. Therefore, in order to ensure the sealing performance between the pot lid and the inner pot, existing pressure cooking appliances generally place the steamer on the necking section of the inner pot neck. However, this placement method makes the steamer still close to the mouth of the inner pot. Although it ensures the volume of the lower cooking cavity, the available space in the cavity above the steamer is small, and it is difficult to place ingredients with a large volume. In addition, many exhaust components such as a float valve and a pressure relief valve are also provided on the pot lid of the pressure cooking appliance. When there is a lot of food in the steamer or the soup boils, the food is likely to interfere with the movement of the exhaust components, causing the exhaust components to be unable to exhaust normally, or the soup to overflow from the exhaust components, thus affecting the reliable progress of pressure cooking and the use experience. Summary of the Utility Model

[0005] The utility model provides a pressure cooking appliance to solve the problems that when partition components such as a steamer are placed inside the inner pot, the space above the steamer is small, affecting the placement of food, and the ingredients in the steamer are easily interfered with by the exhaust components on the pot lid, resulting in abnormal exhaust and soup overflow.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A pressure cooking appliance, comprising a pot body, an inner pot disposed within the pot body, and a partition member disposed inside the inner pot. The partition member divides the inner space of the inner pot into two cooking chambers arranged vertically. The side wall of the inner pot is provided with a neck closing section and a waist pressure bearing section located below the neck closing section. The waist pressure bearing section is used to abut against the pot body so that the pot body supports the inner pot through the waist pressure bearing section, and the partition member rests on the waist pressure bearing section.

[0008] The pressure cooking appliance of the present utility model further has the following additional technical features:

[0009] The waist pressure bearing section is recessed towards the inside of the inner pot to form a supporting step. The partition member is provided with a resting flanging, and the resting flanging is placed on the supporting step.

[0010] The supporting step extends obliquely downwards. The inner diameter of the inner pot at the top of the supporting step is D1, the inner diameter of the inner pot at the bottom of the supporting step is D2, and the outer diameter of the partition member is D. Among them, D2 < D < D1.

[0011] The inner pot is a non-coated structure. The inner surface of the inner pot is provided with etched patterns. The partition member is in contact and abuts with the etched patterns, so that the waist pressure bearing section has a contact area in contact with the partition member and an avoidance area separated from the partition member.

[0012] Inside the inner pot, there is a first cooking chamber located below the partition member and a second cooking chamber located above the partition member. The side wall of the first cooking chamber is provided with a water level line for marking the water level of steam cleaning.

[0013] The partition member has a supporting surface. The supporting surface is provided with air passing ports. There is an air passing gap between a partial area on the outer peripheral side of the partition member and the waist pressure bearing section.

[0014] A holding hole is provided in the central area of the partition member.

[0015] The partition member includes a supporting portion and a cooperating portion surrounding the outer periphery of the supporting portion. The cooperating portion is used for abutting and cooperating with the waist pressure bearing section. The supporting portion is sunken relative to the cooperating portion, so that the supporting surface of the supporting portion is lower than the cooperating portion.

[0016] The side wall of the inner pot bulges outwards between the neck closing section and the waist pressure bearing section to form an arc section between the neck closing section and the waist pressure bearing section.

[0017] The inner pot is provided with a vertical section above the neck closing section. The pressure cooking appliance further includes a pot lid. The pot lid is provided with a sealing ring. The sealing ring has a sealing lip extending downwards. The sealing lip is located inside the inner pot and abuts and seals with the vertical section.

[0018] Due to the adoption of the above technical solutions, the beneficial effects achieved by the present utility model are:

[0019] 1. In the present utility model, the waist pressure-bearing section of the inner liner cooperates and abuts against the pot body, enabling the pot body to support the waist of the inner liner, realizing the transfer of pressure from the inner liner to the pot body through the waist. Compared with pressure transfer through the rim, a gap can be formed between the flanging of the inner liner and the rim of the pot body, facilitating the taking and placing of the inner liner. Compared with pressure transfer through the bottom, the internal structure layout of the cooking appliance is optimized, the space utilization rate is improved, the bottom space of the inner liner is released, and the arrangement of components such as the temperature measuring element is facilitated. At the same time, the bottom space of the inner liner is increased, facilitating the assembler to assemble the components located below the inner liner, reducing the assembly difficulty, avoiding the situation of assembling multiple components in a narrow space, and thus improving the production efficiency of the pressure cooking appliance.

[0020] In addition, in addition to being used for abutting against the pot body for pressure transfer, the waist pressure-bearing section also serves as a placement position for the partition. Placing the partition on the waist pressure-bearing section makes the placement position of the partition in the middle and lower part of the inner liner, that is, the waist of the inner liner. Thus, on the one hand, the cooking space above the partition is increased, enabling larger-sized ingredients to be placed in the upper space. On the other hand, the distance between the supporting surface of the partition and the pot lid is also increased, reducing the risk of interference between the ingredients on the partition and the exhaust components on the pot lid, and the risk of the soup in the upper cooking space overflowing from the exhaust components, ensuring the safe and reliable operation of pressure cooking and improving the user experience.

[0021] 2. As a preferred embodiment of the present utility model, the waist pressure-bearing section is recessed towards the inside of the inner liner to form a supporting step. The supporting step extends obliquely downwards. The inner diameter of the inner liner at the top of the supporting step is D1, the inner diameter at the bottom of the supporting step is D2, and the outer diameter of the partition is D. Among them, D2 < D < D1. During the process of the waist pressure-bearing section extending downwards from top to bottom, it gradually contracts towards the inside of the inner liner to form a stepped surface that extends obliquely downwards on the supporting step. When the inner liner is placed on the stepped surface, due to the inclination of the stepped surface, the inner liner will tend to slide down along the stepped surface under its own gravity, and then the inner liner will slide under the action of gravity to a position centered with the pot body, keeping the axes of the inner liner and the pot body coincident. Furthermore, the pot lid sealing ring is in good contact with the rim of the inner liner, forming a seal to prevent air leakage caused by poor contact in some areas between the sealing ring and the rim of the inner liner. At the same time, the outer diameter of the partition is larger than the inner diameter of the supporting step and smaller than the outer diameter of the supporting step, which not only makes the placement of the partition on the supporting step more stable, but also can limit the left-right shaking amplitude of the partition and prevent the partition from falling below the supporting step.

[0022] 3. As a preferred embodiment of the present utility model, the inner container is a structure without a coating. The inner surface of the inner container is provided with etched patterns. The partition member is in contact and abuts with the etched patterns, so that the waist pressure-bearing section has a contact area in contact with the partition member and an avoidance area separated from the partition member. In the present utility model, the inner container is a structure without a coating. For example, the inner container is made of stainless steel, which can not only avoid the coating on the inner container from falling off due to long-term use or scratching by cookware, but also improve the service life of the inner container. Moreover, in the middle and late stages of cooking, by blowing cold air onto the outer surface of the inner container, the water vapor inside the inner container can be liquefied when it meets the cold, and a layer of moist film is formed on the inner wall of the inner container, so that the non-coated inner container has a good non-stick effect. In addition, due to the processing technology of the non-coated inner container, etched patterns are formed on the inner wall of the inner container. The etched patterns are also arranged in the waist pressure-bearing section. After the partition member is placed in the waist pressure-bearing section, due to the existence of the etched patterns, the partition member contacts the protruding parts of the etched patterns, and there is a gap between the partition member and the concave parts of the etched patterns, thereby reducing the contact area between the partition member and the waist pressure-bearing section, increasing the unit force, making the partition member less likely to shake, and improving the placement stability. At the same time, the gap between the partition member and the waist pressure-bearing section can also be used for the passage of air flow, so that the high-temperature steam in the cooking space below the partition member can flow through this gap and rise to the upper part of the partition member to heat the food in the upper cooking space, improving the heating efficiency of the upper food.

[0023] 4. As a preferred embodiment of the present utility model, the inner part of the inner container has a first cooking cavity located below the partition member and a second cooking cavity located above the partition member. The side wall of the first cooking cavity is provided with a water level line for marking the water level of steam cleaning. In this embodiment, a water level line for marking the water level of steam cleaning is provided on the side wall of the lower first cooking cavity, so that users can use the steam cleaning function more conveniently and achieve steam cleaning. Specifically, the user can place tableware in the partition member, add water to the first cooking cavity, and then heat the water in the first cooking cavity to generate high-temperature steam and form a high-pressure environment inside the inner container, so as to perform high-temperature and high-pressure steam cleaning on the tableware. While improving the cleaning effect, it can also disinfect the tableware by using high temperature and high pressure, thus enriching the functions of the pressure cooking appliance and improving the use experience.

[0024] 5. As a preferred embodiment of the present utility model, a vertical section is provided above the neck closing section of the inner container. The pressure cooking appliance further includes a pot lid, and the pot lid is provided with a sealing ring. The sealing ring has a sealing lip extending downward. The sealing lip is located inside the inner container and abuts against the vertical section for sealing. The vertical section makes the abutment with the sealing ring closer and more stable, thereby improving the sealing effect at the pot opening, ensuring normal pressure build-up inside the pot, and avoiding air leakage. At the same time, after the pressure builds up inside the pot, under the action of the air pressure, the sealing lip will expand and deform outward. Since the sealing lip is located inside the vertical section, its deformation will be blocked by the vertical section, further making the abutment between the sealing lip and the vertical section closer, and thus improving the sealing effect.

In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.

[0040] Such as Figure 1 、 Figure 2As shown in the figure, a pressure cooking appliance includes a pot body, an inner pot 1 placed inside the pot body, and a partition member 2 disposed inside the inner pot 1. The partition member 2 divides the inner space of the inner pot 1 into two cooking chambers arranged vertically. The side wall of the inner pot 1 is provided with a neck closing section 13 and a waist pressure-bearing section 14 located below the neck closing section 13. The waist pressure-bearing section 14 is used to abut against the pot body so that the pot body supports the inner pot 1 through the waist pressure-bearing section 14, and the partition member 2 abuts against the waist pressure-bearing section 14.

[0041] It should be noted that the structure of the partition member 2 is not limited in the present utility model. In one embodiment, the partition member 2 is a steamer structure, that is, openings are provided in the bottom wall and / or side wall of the partition member 2 so that the steam below can surge upward to the upper side of the partition member 2, and at the same time, the liquid inside the partition member 2 can also flow through the openings to the lower side, thereby ensuring that the inside of the partition member 2 is relatively dry for better steaming cooking (such as steaming buns, steaming stuffed buns, etc.). In another embodiment, no opening is provided in the bottom wall of the partition member 2 so that the inside of the partition member 2 can store liquid, enabling the user to cook soup ingredients or steam rice in the upper space.

[0042] It can be understood that in order to ensure that the partition member 2 can pass through smoothly and avoid interference with the inner pot 1 when taking out and placing the partition member 2, the inner diameter of the neck closing section 13 needs to be greater than the outer diameter of the partition member 2.

[0043] As a preferred embodiment of the present utility model, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 shown in the figure, the waist pressure-bearing section 14 is recessed toward the inside of the inner pot 1 to form a supporting step 141, and the partition member 2 is provided with a latching flange 21, and the latching flange 21 is placed on the supporting step 141.

[0044] The waist pressure-bearing section 14 is recessed toward the inside of the inner pot 1, which not only forms a mating boss on the outer surface of the inner pot 1 for abutting against the pot body to form a support, but also forms a supporting step 141 on the inner surface of the inner pot 1 for placing the partition member 2, thereby endowing the waist pressure-bearing section 14 with more functions. It can be used for pressure transmission between the inner pot 1 and the pot body, and also realizes the placement of the partition member 2. Moreover, the structure of the waist pressure-bearing section 14 is simple and convenient to process.

[0045] Preferably, the pot body includes an outer cover and a heat preservation cover placed inside the outer cover. The side wall of the heat preservation cover is provided with an inward recessed portion corresponding to the position of the waist pressure-bearing section 14 to form a supporting boss for supporting the waist pressure-bearing section 14.

[0046] The provision of the abutting flange 21 increases the strength of the edge area of the partition member 2, such that when a relatively heavy food item is placed within the partition member 2, the abutting position of the partition member 2 deforms under the pressure of the food's gravity. At the same time, the abutting flange 21 also makes the edge of the partition member 2 more rounded, enhancing the comfort when a user holds the partition member 2 by hand.

[0047] Specifically, as Figure 4 shown, the abutting flange 21 extends downward in a curved manner to form an arc-shaped curled edge structure.

[0048] It should be noted that the present utility model does not limit the material of the partition member 2. In a preferred embodiment, the partition member 2 is made of a metal material, such as stainless steel, etc., to have better heat resistance. Of course, the partition member 2 can also be made of a plastic material to make the partition member 2 lighter and easier to pick up and place.

[0049] Furthermore, as Figure 3 、 Figure 6 shown, the supporting step 141 extends obliquely downward. The inner diameter of the inner container 1 at the top of the supporting step 141 is D1, the inner diameter at the bottom of the supporting step 141 is D2, and the outer diameter of the partition member 2 is D, where D2 < D < D1.

[0050] During the process of the waist pressure-bearing section 14 extending downward, it gradually contracts inwardly into the inner container 1 to form a stepped surface that extends obliquely downward at the supporting step 141. At the same time, the inner diameter of the top of the supporting step 141 is the largest, the inner diameter of the bottom is the smallest, and the inner diameter of the space enclosed by the supporting step 141 gradually decreases from top to bottom.

[0051] When the inner container 1 is placed on the stepped surface, due to the inclination of the stepped surface, the inner container 1 will tend to slide downward along the stepped surface under its own gravity, and then the inner container 1 will slide under the action of gravity to a position centered with the pot body, keeping the axes of the inner container 1 and the pot body coincident. Furthermore, the lid sealing ring is in good contact with the rim of the inner container 1 to form a seal, preventing air leakage due to poor contact in some areas between the sealing ring and the rim of the inner container 1. At the same time, the outer diameter of the partition member 2 is larger than the inner diameter of the supporting step 141 and smaller than the outer diameter of the supporting step 141, which not only makes the placement of the partition member 2 on the supporting step 141 more stable, but also can limit the left-right swaying amplitude of the partition member 2 and prevent the partition member 2 from falling below the supporting step 141.

[0052] In a preferred embodiment, as Figure 4 shown, the inner container 1 is a non-coated structure, and the inner surface of the inner container 1 is provided with etched patterns 17. The partition member 2 is in mating abutment with the etched patterns 17, such that the waist pressure-bearing section 14 has a contact area 142 in contact with the partition member 2 and an avoidance area 143 separated from the partition member 2.

[0053] It should be noted that "no coating" means that the inner container 1 has no non-stick coating at least on the inner wall, and the present utility model does not limit whether there is a coating for beautifying the appearance on the outer wall of the inner container 1.

[0054] In the present utility model, the inner container 1 has a non-coated structure. For example, the inner container 1 is made of stainless steel, which can not only avoid the coating on the inner container 1 from falling off due to long-term use or scratching by cooking utensils, and improve the service life of the inner container 1. But also in the middle and late stages of cooking, by blowing cold air to the outer surface of the inner container 1, the water vapor inside the inner container 1 is cooled and liquefied to form a layer of moist film on the inner wall of the inner container 1, so that the non-coated inner container 1 has a good non-stick effect.

[0055] In addition, due to the processing technology of the non-coated inner container 1, etching lines 17 are formed on the inner wall of the inner container 1. The etching lines 17 are also arranged in the waist pressure-bearing section 14. After the partition member 2 is placed in the waist pressure-bearing section 14, due to the existence of the etching lines 17, the partition member 2 contacts the protruding parts of the etching lines 17, and there is a gap between the partition member 2 and the concave parts of the etching lines 17. Thus, the contact area between the partition member 2 and the waist pressure-bearing section 14 is reduced, the unit stress is increased, making the partition member 2 less likely to shake, and improving the placement stability. At the same time, the gap between the partition member 2 and the waist pressure-bearing section 14 can also be used for the passage of air flow, so that the high-temperature steam in the cooking space below the partition member 2 can surge through this gap to the upper part of the partition member 2 to heat the food in the upper cooking space, improving the heating efficiency of the upper food.

[0056] As a preferred embodiment of the present utility model, as Figure 1 shown, the inner part of the inner container 1 has a first cooking cavity 11 located below the partition member 2 and a second cooking cavity 12 located above the partition member 2. A water level line 16 for marking the steam cleaning water level is provided on the side wall of the first cooking cavity 11.

[0057] In this embodiment, a water level line 16 for marking the steam cleaning water level is provided on the side wall of the lower first cooking cavity 11, so that users can use the steam cleaning function more conveniently and realize steam cleaning. Specifically, the user can place tableware in the partition member 2, add water to the first cooking cavity 11, and then heat the water in the first cooking cavity 11 to generate high-temperature steam and form a high-pressure environment inside the inner container 1, so as to perform high-temperature and high-pressure steam cleaning on the tableware. While improving the cleaning effect, it can also disinfect the tableware by using high temperature and high pressure, thus enriching the functions of the pressure cooking appliance and improving the use experience.

[0058] It should be noted that the present embodiment does not limit the marking method of the water level line 16, which can be formed by etching, setting convex ribs, etc., and can also be paired with words, patterns, etc.

[0059] Preferably, as Figure 2 shown,Figure 5 As shown, the partition member 2 has a supporting surface, and a gas passage opening 25 is formed in the supporting surface. There is a gas passage gap between a partial area on the outer peripheral side of the partition member 2 and the waist pressure-bearing section 14.

[0060] It can be understood that the heating device is located below the inner container 1. When the partition member 2 is placed inside the inner container 1, the heating device heats the cooking space below the partition member 2. The water in the lower cooking space is heated to form water vapor, which flows upward together with the hot air flow below, and floods into the cooking space above the partition member 2 through the gas passage opening 25 and the gas passage gap to heat the upper-layer food.

[0061] The setting of the gas passage opening 25 and the gas passage gap increases the communication area between the upper and lower cooking spaces, enabling more hot air to enter the upper cooking space per unit time, thereby improving the heating efficiency of the upper cooking space and making the upper and lower-layer foods heated evenly.

[0062] The present utility model does not limit the way of taking and placing the partition member 2. In one embodiment, the user can lift the partition member 2 by holding the edge area of the partition member 2. In another embodiment, as Figure 5 、 Figure 6 shown, a holding hole 24 is provided in the central area of the partition member 2.

[0063] In this embodiment, the user can hook the partition member 2 by passing the fingers through the holding hole 24 and then hooking the partition member 2, so as to lift the partition member 2, which can avoid the hand from contacting the inner wall of the inner container 1 when taking the partition member 2. Since the temperature of the inner wall of the inner container 1 is relatively high, scalding can be avoided.

[0064] As Figure 5 、 Figure 6 shown, the partition member 2 includes a supporting portion 23 and a matching portion 22 surrounding the outer periphery of the supporting portion 23. The matching portion 22 is used for abutting and matching with the waist pressure-bearing section 14. The supporting portion 23 is set to sink relative to the matching portion 22, so that the supporting surface of the supporting portion 23 is lower than the matching portion 22.

[0065] The supporting portion 23 is set to sink relative to the matching portion 22. Further, when the partition member 2 is placed, the side wall of the supporting portion 23 can form positioning with the waist pressure-bearing section 14, which helps the user to place the partition member 2 in the center, so that the waist pressure-bearing section 14 forms a stable supporting force around the partition member 2 and avoids the partition member 2 from tipping over. At the same time, the supporting portion 23 sinks into a groove structure, which can also play a role in limiting the food placed on the supporting surface, keeping the food position stable, and also avoiding the food on the partition member 2 from sliding to the edge and contacting the inner wall of the inner container 1 to cause adhesion.

[0066] Preferably, as Figure 1 、 Figure 2 、 Figure 3As shown, the side wall of the inner pot 1 bulges outwards between the neck closing section 13 and the waist pressure-bearing section 14 to form an arc section 15 between the neck closing section 13 and the waist pressure-bearing section 14.

[0067] The arc surface between the neck closing section 13 and the waist pressure-bearing section 14 is complete, the appearance is neat, and the polishing process is simpler and more convenient. Moreover, heat is transferred more quickly on the smooth arc section 15, so that rapid uniform heating of the arc section 15 can be achieved. At the same time, the arc section 15 forms a heat accumulation space with a larger diameter in the area inside the inner pot 1 corresponding to above the partition member 2, thereby gathering more heat in the upper cooking space and improving the heating effect of the food in the upper cooking space.

[0068] The present utility model does not limit the heating method of the pressure cooking appliance. In one embodiment, a heating plate is provided below the inner pot 1 to heat the inner pot 1 by contacting the bottom of the inner pot 1. In another embodiment, an electromagnetic wire coil is provided below the inner pot 1 to heat the inner pot 1 by electromagnetic heating, realizing non-contact heating and improving the heating efficiency at the same time. Preferably, the electromagnetic wire coil has a bottom coil and a side coil. The bottom coil corresponds to the bottom wall of the inner pot 1, and the side coil corresponds to the waist pressure-bearing section 14 or the arc section 15 to achieve three-dimensional surrounding heating, improve the heating efficiency, and the heat reception uniformity of the upper and lower layer foods.

[0069] In a preferred implementation manner, as Figure 1 、 Figure 3 shown, a vertical section 18 is provided above the neck closing section 13 of the inner pot 1. The pressure cooking appliance further includes a pot lid. The pot lid is provided with a sealing ring. The sealing ring has a sealing lip extending downwards. The sealing lip is located inside the inner pot 1 and abuts against the vertical section 18 for sealing.

[0070] The vertical section 18 makes the abutment with the sealing ring closer and more stable, thereby improving the sealing effect of the pot mouth, ensuring normal pressure build-up in the pot, and avoiding air leakage. At the same time, after the pressure builds up in the pot, under the action of the air pressure, the sealing lip will expand and deform outwards. Since the sealing lip is located inside the vertical section 18, its deformation will be blocked by the vertical section 18, further making the abutment between the sealing lip and the vertical section 18 closer, and thus improving the sealing effect.
