Description

Technical Field

[0001] The present invention relates to the field of household appliances, and in particular to a cooking utensil. Background Art

[0002] Drained rice has a lower sugar content, making it particularly beneficial for diabetics. Compared to stewed rice, the gelatinization of the rice can be better controlled during the cooking process, resulting in fuller, more elastic grains. However, the specialized production process for drained rice makes currently available drained rice cookers limited in functionality. They can only be used for making drained rice, but are unable to perform multiple functions such as cooking porridge or stewing rice, failing to meet people's daily needs.

[0003] In addition, the drain rice cookers currently on the market mainly form a pressure difference that promotes water flow by adjusting the air pressure of the inner pot or the outer pot, so the arrangement of the air duct has become the main technical point of the drain rice cooker. In order to simplify the arrangement of the air duct, some drain rice cookers use the method of regulating the pressure of the inner pot to form a pressure difference, but when the drain rice cooker with this structure is heated and cooked, the water in the outer pot can easily enter the inner pot again to soak the rice, causing the rice to gelatinize excessively, that is, the gelatinization degree of the rice grains is difficult to control accurately. The current drain rice cooker based on regulating the pressure of the outer pot transmits or extracts air through the air holes on the side wall of the outer pot, but because the air holes are located on the side wall of the outer pot, a blind spot is formed at the air duct interface after the outer pot is placed. It is difficult to locate between the air holes on the side wall of the outer pot and the air duct, which is very prone to leakage. In addition, the air duct structure also makes it inconvenient to clean the outer pot and the seal. Summary of the Invention

[0047] Example 1

[0048] The existing rice cooker with draining function is single and can only be used to make draining rice but cannot realize other cooking functions. In addition, the existing rice cooker with draining function has problems such as difficult positioning, unsatisfactory sealing effect and difficulty in cleaning in terms of air channel distribution.

[0049] In view of this, the present embodiment provides a cooking appliance that can realize multiple cooking modes and is very convenient for users to use. Figures 1 to 17 As shown, the cooking device provided in this embodiment includes a pot body 1, an outer pot 2, a steaming assembly 3, a pressure regulating assembly 4, a pot lid 5, and a heating element 6. The outer pot 2 is disposed within the pot body 1 and has an air guide hole 100 on its rim 21. The steaming assembly 3 includes an inner pot 31 and an inner pot sealing ring 32. The inner pot 31 is detachably disposed within the outer pot 2 and forms a pressure chamber 20 with the outer pot 2. The inner pot sealing ring 32 includes a sealing portion 321 and a connecting portion 322. The sealing portion 321 is located radially outward from the air guide hole 100 and is pressed between the inner pot rim 311 and the outer pot rim 21. The connecting portion 322 abuts against the inner pot outer wall 312 to tighten the inner pot sealing ring 32. An air channel connecting the air guide hole 100 and the pressure chamber 20 is formed between the inner pot sealing ring 32 and the outer pot 2 opposite to it. A pressure-regulating assembly 4 is mounted within the pot body 1 and is sealed in communication with the air duct 100. This assembly is used to regulate the pressure within the pressure chamber 20. Alternatively, when the degassing assembly 3 is removed, it can supply air to the outer pot 2 to lower the temperature of the liquid within the outer pot 2. The pot lid 5 is sealed to the inner pot 31 via a lid sealing ring 53. Alternatively, when the degassing assembly 3 is removed, the pot lid 5 can be sealed to the outer pot 2 via the lid sealing ring 53. A heating element 6 is mounted within the pot body 1 to heat the outer pot 2.

[0050] The detachable structure of the steaming assembly 3 in the cooking device provided in this embodiment allows it to be used for making low-sugar rice or, when the steaming assembly 3 is removed, for cooking porridge or stewed rice. When operating in traditional rice cooker mode, the lid 5 is required to be tightly closed to the outer pot 2 via the lid sealing ring 53. However, since a sealed pressure chamber 20 must be formed between the inner pot 31 and the outer pot 2 during rice cooking, the outer pot 2 and the lid 5 must accommodate not only the inner pot rim 311 but also the inner pot sealing ring 32. The sealing distance between the lid 5 and the outer pot 2 is determined by the thickness of the inner pot rim 311, the thickness of the inner pot sealing ring 32, and the thickness of the structure that secures the inner pot sealing ring 32. If this sealing distance is too large, the lid 5 will not be able to seal the outer pot 2 after the steaming assembly 3 is removed, preventing normal operation in traditional rice cooker mode.

[0051] In existing household appliances, the sealing ring is primarily secured with a buckle, which is then radially tightened using an annular groove. The presence of the buckle and annular groove inevitably increases the thickness of the inner pot rim, thereby increasing the sealing distance between the lid and the outer pot. However, placing the buckle and annular groove on the outer pot rim would compromise the seal between the lid and the outer pot. Furthermore, since both the inner and outer pots are typically made of metal, glass, or ceramic, creating the buckle and annular groove is challenging. Furthermore, in this embodiment, the design of the inner pot sealing ring also requires consideration of airway distribution.

[0052] In order to solve this contradiction, the cooking appliance provided in this embodiment has the following features: Figures 3 to 6 As shown, the inner pot sealing ring 32 is secured without clips. The sealing portion 321 is pressed tightly between the inner pot rim 311 and the outer pot rim 21 by the weight of the inner pot 31, sealing the inner pot 31 and the outer pot 2 while also securing the inner pot 31 and the outer pot 2. Simultaneously, the connecting portion 322 of the inner pot sealing ring 32 is positioned to abut against the inner pot outer wall 312, thereby tightening the inner pot sealing ring 32 in the radial direction. The inner pot sealing ring securing method provided in this embodiment, which does not require clips or annular grooves, ensures that the sealing distance between the lid 5 and the outer pot 2 depends solely on the thickness of the inner pot rim 311 and the sealing portion 321, without considering the thickness of the inner pot sealing ring securing structure. This significantly shortens the distance between the lid 5 and the outer pot 2, allowing the cooking appliance to operate in traditional rice cooker mode. Furthermore, the sequential placement of the pot body 1, the outer pot 2, and the inner pot 31 makes the cooking utensil provided in this embodiment an integrated structure, which is not only convenient to use but also has good heat preservation performance of the inner pot 31. Therefore, it can be made of a single-layer material with a thinner thickness, thereby further shortening the sealing distance between the pot cover 5 and the outer pot 2, thereby ensuring the sealing effect between the two.

[0053] Regarding the distribution of the air passage, since the sealing portion 321 is located outside the air guide hole 100 and the inner pot sealing ring 32 extends along the lower surface of the inner pot rim 311, an air passage connecting the air guide hole 100 and the pressure chamber 20 is formed between the inner pot sealing ring 32 and the outer pot 2, thereby achieving air communication. Specifically, the connecting portion 322 includes a radial connecting portion 3221 and an axial connecting portion 3222. The radial connecting portion 3221 connects to the sealing portion 321 and is in close contact with the bottom of the inner pot rim 311. The axial connecting portion 3222 extends toward the bottom of the pot body 1 and abuts against the inner pot outer wall 312. The air guide channel includes a first air guide channel 3201 and a second air guide channel 3202; wherein, the first air guide channel 3201 connecting to the air guide hole 100 is formed between the radial connecting part 3221 and the outer pot edge 21, and the second air guide channel 3202 connecting to the pressure chamber 20 is formed between the axial connecting part 3222 and the outer pot body 22.

[0054] In summary, the inner pot sealing ring 32 provided in this embodiment shortens the sealing distance between the pot lid 5 and the outer pot 2 while effectively ensuring airway communication between the air guide hole 100 and the pressure chamber 20. Furthermore, due to the guidance of the inner pot outer wall 312 and the inner pot rim 311, and the large angle bend between the radial connection portion 3221 and the axial connection portion 3222, the inner pot sealing ring 32 has an open structure. Compared with the double-lip sealing rings used in existing household appliances, this structure is more convenient to clean.

[0055] In the rice-draining cooking mode, the pressure-regulating assembly 4 delivers or extracts air to the pressure chamber 20 through the air holes 100 and the air channel to change the pressure within the pressure chamber 20, thereby promoting water flow between the outer pot 2 and the inner pot 31, thereby soaking and draining the rice. In the porridge cooking mode of a traditional rice cooker, the pressure-regulating assembly 4 delivers cold air to the outer pot 2 through the air holes 100 to lower the temperature of the rice soup within the outer pot. This controls the temperature of the rice soup within a certain range, allowing the rice grains to gradually gelatinize and release their essence within this temperature range, simulating a slow-cooking process over a firewood stove.

[0056] In this embodiment, if Figure 3 、 Figure 4 、 Figure 7 as well as Figure 8As shown, the pressure regulating assembly 4 includes an air pump 41 and a flexible air duct 42. The pot body 1 has a pot air passage 11 extending to its upper end surface. The bottom end of the pot air passage 11 connects to the flexible air duct 42, while the top end of the pot air passage 11 is sealedly connected to an air duct 100 in the outer pot rim via an axial air hole 70 in the outer pot sealing ring 7. Because the pot air passage 11 is stable and unchanging, after cleaning the outer pot 2, assembly requires only aligning the air duct 100 with the axial air hole 70 in the outer pot sealing ring 7. Furthermore, the positioning of the air duct 100 is visually detectable, making alignment very convenient and accurate. However, the present invention is not limited to this. In other embodiments, the pot body may simply provide a channel for the pressure regulating assembly's air duct to pass through, with the air duct directly connected to the air passage.

[0057] In order to further simplify the assembly of the outer pot 2, in this embodiment, Figure 4 、 Figure 5 as well as Figure 10 As shown, the outer pot sealing ring 7 comprises an annular ring body 71 and two annular sealing flaps 72 located on the upper surface of the ring body 71. The annular ring body 71 has an axial air hole 70. The outer pot rim 21 abuts against the two annular sealing flaps 72. An annular air channel 710 is formed circumferentially between the outer pot rim 21, the two annular sealing flaps 72, and the upper surface of the annular ring body 71, connecting to the axial air hole 70. Due to the circumferential continuity of the annular air channel 710, the air guide hole 100 on the outer pot rim 21 and the axial air hole 70 can be connected without positioning, greatly facilitating assembly of the outer pot 2 after cleaning. However, the present invention is not limited to this. In other embodiments, the pot body air channel can also be connected to the air guide hole via a flexible air nozzle, in which case the outer pot sealing ring is unnecessary.

[0058] As described above, based on the detachable structure of the steaming assembly 3, the inner pot sealing ring 32 and the distribution of the air passage, the cooking appliance provided in this embodiment can have multiple cooking modes, realizing multiple uses of one machine. Figures 1 to 17 Introducing various cooking modes.

[0059] The first cooking mode is the draining rice cooking mode. In this mode, the draining assembly 3 is placed in the outer pot 2 and includes a focusing hood 33 sealed to the bottom of the inner pot 31. The bottom of the inner pot 31 has a drain groove connected to the focusing hood 33. A water flow channel is defined between the bottom of the focusing hood 33 and the inner bottom wall of the outer pot 2. The water in the outer pot 2 submerges the water flow channel. The pot lid 5 seals the inner pot 31. The pressure regulating assembly 4 supplies air to the pressure chamber 20 through the pot body air passage 11, the axial air hole 70, the annular air passage 710, the air guide hole 100, the first air guide passage 3201, and the second air guide passage 3202. As the pressure in the pressure chamber 20 increases, the water in the outer pot 2 enters the focusing hood 33 through the water flow channel, rises through the drain groove, and enters the inner pot 31 to soak the rice. After the rice has soaked to the desired level, the pressure regulating assembly 4 reduces the pressure in the pressure chamber 20, allowing the water in the inner pot 31 to fall back into the outer pot 2 through the drain trough and energy collecting hood 33, completing the draining process. The heating element 6 is then activated, heating the water in the energy collecting hood 33 to generate steam, which steams the rice in the inner pot 31. The steam is then discharged through the steam vents in the lid 5. During the steaming process, the pressure in the pressure chamber 20 can be adjusted again or multiple times to allow water from the outer pot 2 to enter the inner pot 31 for a short period of replenishment, followed by draining. After draining is complete, the steam continues to heat the rice until it is cooked.

[0060] In this embodiment, the energy-gathering hood 33 comprises an outer energy-gathering hood 331, an inner energy-gathering hood 332, and an energy-gathering hood sealing ring 333. A first water flow channel is defined between the inner energy-gathering hood 332 and the inner bottom wall of the outer pot 2. A second water flow channel, connected to the outer pot 2, is defined between the outer energy-gathering hood 331 and the inner energy-gathering hood 332. The top of the inner energy-gathering hood 332 has steam holes connected to a drain trough. The inner pot 31 is connected to the outer energy-gathering hood 331 via the energy-gathering hood sealing ring 333. The heating element 6 heats the water in the inner energy-gathering hood 332 to rapidly generate steam, which then enters the inner pot 31 through the steam holes at the top of the inner energy-gathering hood 332 and the drain trough at the bottom of the inner pot 31.

[0061] In this embodiment, the heating element 6 is an electromagnetic coil, and the outer pot 2 is made of a magnetic conductive metal material; the diameter of the heating element 6 is close to the inner diameter of the energy-gathering inner cover 332. However, the present invention does not impose any limitation on this. In other embodiments, the diameter D3 of the electromagnetic coil can be set to be 2-10 mm smaller than the inner diameter D2 of the energy-gathering inner cover 332 so that heat is concentrated in the energy-gathering inner cover 332 during heating, thereby quickly generating steam (as shown in Example 2). Alternatively, the heating element can be provided to include an inner electromagnetic coil and an outer electromagnetic coil. In the drained rice making mode, the inner electromagnetic coil is used to heat the energy-gathering inner cover; while in the traditional rice cooker mode, the inner and outer electromagnetic coils work together to improve the uniformity and efficiency of heating.

[0062] In this embodiment, the inner pot 31 transmits water and steam through multiple drain grooves at the bottom. Because the width of the drain grooves is approximately 1.5 mm, smaller than the short diameter of a rice grain, the rice layer can be placed directly on the bottom of the inner pot 31, serving as a steaming tray. However, the present invention is not limited to this. In other embodiments, multiple larger water holes can be provided in the bottom of the inner pot to facilitate water and steam transmission, with the rice layer then placed on the steaming tray within the inner pot.

[0063] In this embodiment, if Figures 12 to 16 As shown, the bottom of the inner pot includes a raised portion 313 and a peripheral portion 314. The raised portion 313 protrudes upward relative to the peripheral portion 314 and has multiple radial drain grooves 3130 on the raised portion 313. The peripheral portion 314 has multiple circumferential drain grooves 3140 spaced apart. The provision of the radial drain grooves 3130 and circumferential drain grooves 3140 increases the area for water and steam to pass through, allowing water and steam to enter the inner pot 31 more quickly, or for water to drain out of the inner pot 31 more quickly. Especially during the draining phase, the provision of the radial drain grooves 3130 and circumferential drain grooves 3140 ensures that all areas of the bottom of the inner pot 31 are thoroughly drained, preventing water accumulation in certain areas that could cause the rice at the bottom to become soggy and overly gelatinized.

[0064] In this embodiment, the inner pot 31 is integrally formed after overall stretching. The bottom and side walls of the inner pot 31 are about 2 mm thick, which is close to the diameter of rice. As a result, the rice is easily stuck in the drain trough and is difficult to clean. Figure 15 and Figure 16 As shown, the outer walls of the radial drain grooves 3130 and circumferential drain grooves 3140 are chamfered to form an inclined guide wall 315 whose thickness gradually decreases toward the center. This arrangement allows rice grains stuck in the drain groove to be expelled with a single push of a brush during cleaning, making cleaning very convenient for the user. Preferably, the end thickness of the inclined guide wall 315 is set to be equal to 1 / 4 of the thickness of the starting end. For an inner pot 31 with a wall thickness T1 of 2 mm, the end thickness T2 of the inclined guide wall 315 is 0.5 mm. However, this invention is not limited to this.

[0065] The second cooking mode is the rice cooking mode of a conventional rice cooker. In this cooking mode, the steaming assembly 3 is removed and the rice layer is placed in the outer pot 2, and the pot lid 5 is sealed on the outer pot 2. The heating element 6 heats the water in the outer pot 2 and the rice layer to stew the rice.

[0066] The third cooking mode is the porridge cooking mode. In this cooking mode, the steaming component 3 is removed and the rice layer is placed in the outer pot 2. The pot lid 5 is sealed on the outer pot 2, and the heating element 6 heats the water and the rice layer in the outer pot 2, and the pressure regulating component 4 is opened in stages after the temperature of the rice soup reaches the set requirement. The pressure regulating component 4 inputs low-temperature cold air into the outer pot 2 through the pot body air channel 11, the axial air hole 70, the annular air channel 710 and the air guide hole 100 to reduce the temperature of the rice soup in the outer pot 2, suppress the overflow of the rice soup, and accurately control the gelatinization temperature and gelatinization time of the rice grains. This setting allows the cooking appliance to use high-power heating of the heating element 6 to simulate traditional firewood porridge in the porridge cooking mode, while improving the taste of the rice porridge and effectively avoiding the rice soup bubbles generated by high-power continuous heating from overflowing from the steam port on the pot lid 5.

[0067] Existing kitchen appliances often use a single electrode to detect water levels to prevent dry boiling. However, in this embodiment, the rice layer absorbs water and expands after soaking, and expands again during the steaming process. If a single electrode is used for detection, the expanded rice layer may come into contact with the electrode after draining, causing electrical conductivity and misjudging the electrode.

[0068] In view of this, the present embodiment provides a detection method based on a double water level electrode 8, which realizes water level detection by detecting the resistance between the double water level electrodes 8. Although the resistance value of rice grains will decrease after they absorb water and swell, within the same conductive distance, the resistance between the swollen rice grains will still be greater than the resistance of water, and the resistance difference between the two will become more obvious as the center distance D1 between the two water level electrodes 8 increases. Therefore, the present embodiment realizes accurate detection of two different contact states: the double water level electrodes 8 in contact with water and the two water level electrodes in contact with the rice layer by controlling the center distance D1 between the two water level electrodes 8. In addition, considering that an excessively large center distance D1 will also make it difficult to form a discrimination signal between the two water level electrodes 8. Therefore, preferably, the center distance D1 between the two water level electrodes 8 is set to be greater than or equal to 5 mm and less than or equal to 200 mm.

[0069] Furthermore, during the process of making rice, it is required that the water should completely submerge the rice layer when soaking the rice. To meet this condition, the distance D2 from the end of each water level electrode 8 to the inner bottom wall of the outer peripheral portion 314 of the inner pot 31 that is not raised is set to be greater than or equal to 30 mm (the distance D2 can be obtained from the second embodiment). Figure 18 When the depth of the inner pot 31 is determined, a larger distance D2 indicates a higher water level in the inner pot 31 during soaking of rice.

[0070] Based on the precise identification of the dual water-level electrodes 8, the control board located within the pot lid 5 uses the water-level detection signal to control the operating state of the air pump (pressure-regulating component). Specifically, when soaking rice, if the water level is detected to have reached the dual water-level electrodes 8, the control board outputs a stop signal or an intermittent operation signal to the air pump to maintain the water level in the inner pot 31. Furthermore, the water-level electrodes 8 installed within the pot lid 5 allow all electronic control components of the cooking appliance provided in this embodiment to be located within the pot lid 5, simplifying circuit wiring while effectively preventing the impact of liquid in the pot on circuit components.

[0071] Example 2

[0072] This embodiment is basically the same as the first embodiment and its variations, except for the difference in the composition and structure of the airway.

[0073] like Figures 18 to 24 As shown, the cooking device provided in this embodiment includes a pot body 1, an outer pot 2, a steaming assembly 3, a pot cover 5, a pressure regulating assembly 4, and a heating element 6. The steaming assembly 3 includes an inner pot 31 and an inner pot sealing ring 32. The inner pot 31 is detachably disposed in the outer pot 2 and forms a pressure chamber 20 between the inner pot 31 and the outer pot 2. The inner pot rim 311 has an air guide hole 100. The inner pot sealing ring 32 includes a sealing portion 321 and a connecting portion 322. The sealing portion 321 is located radially outward of the air guide hole 100 and is pressed between the inner pot rim 311 and the outer pot rim 21. The connecting portion 322 abuts against the inner pot outer wall 312 to tighten the inner pot sealing ring 32. An air guide channel connecting the air guide hole 100 and the pressure chamber 20 is formed between the inner pot sealing ring 32 and the inner pot 31 opposite thereto. The pot lid 5 includes a lid body 51 and a lid air passage 52. The lid body 51 is sealed against the inner pot 31 via a lid sealing ring 53, and the lid air passage 52 is connected to the air guide hole 100. Alternatively, when the decanting assembly 3 is removed, the lid 5 can be sealed against the outer pot 2 via the lid sealing ring 53, allowing the lid air passage 52 to connect to the outer pot 2. A pressure regulating assembly 4 is disposed within the pot body 1 and connected to the lid air passage 52. The pressure regulating assembly 4 is used to regulate the pressure within the pressure chamber 20. Alternatively, when the decanting assembly 3 is removed, it can supply air to the outer pot 2 to lower the temperature of the liquid therein. A heating element 6 is disposed at the bottom of the outer pot 2.

[0074] In this embodiment, the pot lid air duct 52 includes an air duct connector 521 and a flexible air nozzle 522 detachably connected to the end of the air duct connector 521. After the pot lid 5 is closed, the air duct connector 521 is sealed and connected to the air guide hole 100 through the flexible air nozzle 522. In this structure, the user can observe the air guide hole 100 and the flexible air nozzle 522 by opening the pot lid 5. Combined with the positioning mark on the edge of the pot body 1 (not shown in the figure), the inner pot 31 can be quickly and accurately placed so that the air guide hole 100 and the flexible air nozzle 522 are sealed and docked. In addition, this setting also greatly facilitates the disassembly, cleaning and replacement of the flexible air nozzle 522.

[0075] In this embodiment, the pressure regulating assembly 4 includes an air pump 41 for supplying and extracting air and an air duct 42. The air pump 41 is housed within the pot body 1 and is adjacent to the pot lid 5. One end of the air duct 42 is connected to the air pump 41, and the other end is connected to the airway connector 521 on the pot lid 5.

[0076] As for the inner pot sealing ring, the inner pot sealing ring 32 is also fixed between the inner pot rim 311, the outer pot rim 21 and the inner pot outer wall 312 in the same manner as in the first embodiment, without buckles or annular grooves, thereby greatly shortening the sealing distance between the pot cover 5 and the outer pot 2, providing conditions for the cooking appliance to work in the traditional rice cooker mode. Specifically, Figure 20 and Figure 21 As shown, the sealing portion 321 is pressed between the inner pot rim 311 and the outer pot rim 21 based on the gravity of the inner pot 31, thereby sealing the inner pot 31 and the outer pot 2 while achieving its own fixation; and the connecting portion 322 is pressed against the inner pot outer wall 312 to tighten the inner pot sealing ring 32 radially.

[0077] In terms of air passage distribution, the connecting portion 322 also includes a radial connecting portion 3221 and an axial connecting portion 3222. The radial connecting portion 3221 is connected to the sealing portion 321, and the axial connecting portion 3222 extends toward the bottom of the pot body 1. Figure 21 and 22 As shown, a portion of the inner circumferential wall of the axial connecting portion 3222 radially protrudes and abuts against the inner pot outer wall 312 to tighten the inner pot sealing ring 32. The air guide channel includes a first air guide channel 3201 and a second air guide channel 3202. The radial connecting portion 3221 and the inner pot rim 311 form the first air guide channel 3201, which connects to the air guide hole 100. The inner wall of the non-protruding axial connecting portion 3222 and the inner pot outer wall 312 form the second air guide channel 3202, which connects to the pressure chamber 20.

[0078] like Figure 21 and Figure 22 As shown, the circumferential wall of the axial connecting portion 3222 has multiple radially protruding ribs 3223 that abut the outer wall of the inner pot 31. Second air-guiding channels 3202 are formed between the non-protruding portions of the axial connecting portion 3222 and the inner pot outer wall 312 between adjacent ribs 3223. Multiple second air-guiding channels 3202 communicate with the circumferentially continuous first air-guiding channel 3201. However, the present invention is not limited to this. In other embodiments, portions of the axial connecting portion may be continuously radially protruding, with the non-protruding portions positioned opposite the air-guiding holes.

[0079] In this embodiment, the first air channel 3201 diverts gas entering from the air hole 100 to multiple second air channels 3202; alternatively, the gas within multiple second air channels 3202 is collected and then output to the air hole 100, thereby uniformly varying the pressure across all areas of the pressure chamber 20. This prevents problems such as poor water flow caused by uneven pressure differentials within the pressure chamber 20 and leakage caused by excessive pressure in certain areas of the inner pot sealing ring 32. This uniform pressure distribution across the entire inner pot sealing ring 32 allows the inner pot sealing ring 32 to utilize a thinner sealing portion 321 to effectively seal the inner pot 31 and outer pot 2. This reduced thickness of the sealing portion 321 further reduces the sealing distance between the lid 5 and the outer pot rim 21, improving the sealing performance in conventional rice cooker operation.

[0080] This embodiment illustrates the formation of a second air-guiding channel between the axial connection portion 3222 of the inner pot sealing ring and the inner pot outer wall 312. However, the present invention is not limited to this. In other embodiments, the entire axial connection portion may be in contact with the inner pot outer wall, and the inner pot sealing ring may include a through hole positioned opposite the air-guiding hole, forming an air-guiding channel connecting the air-guiding hole and the pressure chamber.

[0081] Similarly, compared to the double-lip sealing ring in existing home appliances, the inner pot sealing ring provided in this embodiment has a large angle bend between the radial connecting portion 3221 and the axial connecting portion 3222, so that the inner pot sealing ring 32 has an open structure, and there are no small slots on the inner pot sealing ring 32, so it is very convenient to clean.

[0082] Similar to the first embodiment, the cooking appliance provided in this example also has multiple cooking modes.

[0083] The first cooking method involves draining rice. In this case, the steaming assembly 3 is placed within the outer pot 2 and further includes a collecting hood 33 sealed to the bottom of the inner pot 31. The bottom of the inner pot 31 has a drain trough connected to the collecting hood 33. A water channel is defined between the bottom of the collecting hood 33 and the inner bottom wall of the outer pot 2, and the water within the outer pot 2 submerges the channel. The lid 5 seals the inner pot 31. An air pump 41 delivers air to the pressure chamber 20 via the air duct 42, airway connector 521, flexible air nozzle 522, air holes 100, first air channel 3201, and second air channel 3202. The pressure within the pressure chamber 20 increases, and the water within the outer pot 2 enters the collecting hood 33 through the water channel and then, via the drain trough, into the inner pot 31 to soak the rice. After the rice has been soaked to the desired level, the air pump 41 reduces the pressure in the pressure chamber 20, allowing the water in the inner pot 31 to fall back into the outer pot 2 through the drain trough and energy-gathering hood 33, completing the draining process. The heater 6 is then activated, heating the water in the energy-gathering hood 33 to generate steam that steams the rice layer in the inner pot 31. The steam is then discharged through the steam vents in the lid 5. During the steaming process, the pressure in the pressure chamber 20 can be adjusted again or multiple times to allow water from the outer pot 2 to enter the inner pot 31 for a short period of replenishment, followed by draining. After draining is complete, the steam continues to heat the rice layer until it is cooked.

[0084] The second cooking mode is the rice cooking mode of a conventional rice cooker. In this cooking mode, the steaming assembly 3 is removed and the rice layer is placed in the outer pot 2, and the pot lid 5 is sealed on the outer pot 2. The heating element 6 heats the water in the outer pot 2 and the rice layer to stew the rice.

[0085] The third cooking mode is the porridge cooking mode. In this cooking mode, the steaming component 3 is removed and the rice layer is placed in the outer pot 2. The pot lid 5 is sealed on the outer pot 2, and the heating element 6 heats the water and the rice layer in the outer pot 2. After the temperature of the rice soup reaches the set requirement, the pressure regulating component 4 is opened in stages. The pressure regulating component 4 inputs low-temperature cold air into the outer pot 2 through the air duct 42, the airway joint 521, the flexible air nozzle 522, and the air guide hole 100 to reduce the temperature of the rice soup in the outer pot 2, suppress the overflow of the rice soup, and accurately control the gelatinization temperature and gelatinization time of the rice grains. This setting allows the cooking utensil provided in this embodiment to use high-power heating of the heating element 6 to simulate traditional firewood porridge in the porridge cooking mode, while improving the taste of the rice porridge and effectively avoiding the rice soup bubbles generated by high-power continuous heating from overflowing from the steam port on the pot lid 5.

[0086] In the cooking apparatus provided in this embodiment, the structures of components such as the energy-gathering cover 33, the dual-water-level electrode 8, and the lid sealing ring 53 are identical to those in the first embodiment. The inner pot differs from the first embodiment in that the inner pot rim 311 in this embodiment has air holes 100, while the outer pot lacks these holes. Therefore, further description will be omitted.

[0087] Example 3

[0088] This embodiment is basically the same as the second embodiment and its variations, except that the structure of the pot cover sealing ring 53 ′ is different and the connection method between the pot cover air passage 52 and the air guide hole 100 is different.

[0089] like Figures 25 to 27 As shown, the pot lid sealing ring 53' includes a main body 531', an inner sealing lip 532' and an outer sealing lip 533' located on both sides of the main body 531', and an assembly portion 534'. The assembly portion 534' is engaged with the slot on the lid body 51, and the air duct connector 521 on the pot lid air duct 52 is connected to the main body 531' of the pot lid sealing ring. After the lid body 51 is closed, the inner sealing lip 532' and the outer sealing lip 533' abut against the inner pot rim 311 on the outer periphery of the air guide hole 100, and the inner sealing lip 532', the outer sealing lip 533' and the inner pot rim 311 form a through annular sealing cavity 530', and the through annular sealing cavity 530' connects the air duct connector 521 and the air guide hole 100.

[0090] In the second embodiment, in order to achieve the docking of the air guide hole 100 and the flexible air nozzle 522, the inner pot 31 needs to be positioned according to the positioning mark. In this embodiment, the structure of the pot lid sealing ring 53' is changed so that after the pot lid 5 is closed, the inner sealing lip 532', the outer sealing lip 533' and the inner pot rim 311 form a continuous annular sealing cavity 530'. Based on the circumferential continuity of the annular sealing cavity 530', the inner pot 31 can achieve the connection between the air duct connector 521 and the air guide hole 100 regardless of its placement. That is, on the axial projection surface of the functional cooking utensil, the air duct connector 521 and the air guide hole 100 can be staggered or overlapped. The user does not need to position the inner pot 31 when using it. The air duct connection can be achieved by placing the inner pot 31 at will, which is very convenient to use. Furthermore, the sealed connection between the airway connector 521 and the air guide hole 310 achieved by the pot lid sealing ring 53 ′ eliminates the need for a flexible air nozzle in this embodiment, which not only reduces costs but also greatly facilitates assembly and cleaning.

[0091] Example 4

[0092] This embodiment is basically the same as the second embodiment and its variations. The difference is that: Figure 28 and Figure 29As shown, the cooking utensil further comprises a pressure cooker lid 9, which has a cover tooth (not shown in the figure due to viewing angle) and a pot body 1 having pot teeth 12 that match the cover tooth. This setting will enable the cooking utensil provided in this example to also have a fourth cooking mode, namely a high-pressure cooking mode. In this mode, the pot lid 5 is in an open state and the leaching component 3 is removed from the outer pot 2. The pressure cooker lid 9 is fitted onto the pot body 1 through the cover tooth and the pot teeth 12. A sealed pressure chamber is formed between the pressure cooker lid 9 and the outer pot 2 by the pressure cooker lid sealing ring 91. However, the present invention does not impose any limitation on this. In other embodiments, when the cooking pressure requirement is not high, such as when only a slight pressure is required, it is not necessary to provide the pot teeth and the cover tooth, and it is only necessary to replace the pot lid 5 with a pressure cooker lid with a higher pressure-bearing capacity.

[0093] Although this embodiment describes the high-pressure cooking mode by taking the structure of the second embodiment as an example, similarly, a pressure cooker cover can be added to the structure shown in the first embodiment to realize the high-pressure cooking mode.

[0094] In summary, in the cooking utensil provided by the present invention, the degassing component is entirely contained in the outer pot, and when the pot lid is closed, the entire cooking utensil is integrated, and the structure is very simple. The tightening method of the inner pot sealing ring based on the inner pot edge, the outer pot edge, and the outer wall of the inner pot not only has good airtightness and is easy to install, but also effectively shortens the distance between the outer pot and the pot lid, providing conditions for the pot lid to seal the outer pot after removing the degassing component. Combined with the detachable structure of the degassing component and the distribution of the air duct, the cooking utensil provided by the present invention can have multiple cooking modes; when the degassing component is placed, it can be used to make degassing rice, and after removing the degassing component, it can be used as a traditional rice cooker to stew rice or cook porridge, realizing multiple uses of one machine. In addition, the air guide holes distributed on the pot edge also greatly simplify the positioning connection between it and the pressure regulating component, and the installation of the inner pot and outer pot after cleaning is very convenient.

[0095] Although the present invention has been disclosed above by means of preferred embodiments, this is not intended to limit the present invention. Anyone skilled in the art may make slight changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of protection required by the claims.
