Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and particularly relates to a water-separated stew pot. Background Art

[0002] Water-separated stewing is a cooking method in which raw materials are placed in an inner pot, covered, and then the inner pot is placed in an outer pot filled with water, and heated with a low fire for a long time to stew the raw materials. The cooking method of water-separated stewing can keep the original color of the dishes, the soup is clear, the soup is delicious, and the meat is tender and rotten. Therefore, it is more and more popular among cooks. Based on this, the water-separated stew pot has gradually become one of the most popular cooking utensils.

[0003] In the prior art, the heating device for heating the water in the outer pot is usually arranged at the center of the bottom of the outer pot, and the heating device also corresponds to the center of the inner pot to heat the water in the outer pot. Since the heating device is in the central area, during the heating process, the water at the center will be heated first, and then a large amount of steam will be generated by boiling. The steam surges upward in the water due to buoyancy, and the heating device corresponds to the center of the inner pot. Therefore, the boiling water and the surging steam at the center will gather at the bottom of the inner pot, and then collide with the bottom of the inner pot, generating noise. In addition, a large amount of steam accumulates at the bottom of the inner pot, causing an upward buoyancy on the inner pot. After the steam breaks through the surface tension of the water, it quickly discharges from the side. The buoyancy on the inner pot suddenly decreases, and due to the rapid discharge of the bubbles, the surrounding water quickly replenishes the bottom of the inner pot. The rapid flow of the water also generates an impact force on the inner pot. The combination of these two factors causes the inner pot to generate mechanical vibration. In this way, it repeats continuously, causing the product to generate continuous vibration noise during operation. Since the water-separated stewing generally works for a long time, the continuous noise seriously affects the user experience.

[0004] Based on this, Chinese Patent CN202060584U discloses a low-noise water-separated electric stew pot, which places the heating element at the peripheral position of the bottom of the stew pot (inner pot) to preferentially heat the water at the periphery. By deviating the heating element from directly below the bottom of the stew pot, when the water in the water-containing container is heated to boiling, most of the small bubbles generated during the rising process will not hit the bottom of the stew pot, thereby reducing the phenomenon that the bubble disturbs the water flow and collides with the stew pot to cause the stew pot to vibrate, and playing a role in reducing noise to a certain extent.

[0005] However, in the above solution, although the heating element is arranged outside the stew pot, the area above the heating element is an open water area. When the heating element works, it preferentially heats the outer water area, resulting in a temperature difference between the inner water area and the outer water area. Under the action of the temperature difference, the high-temperature water on the outside will naturally flow to the inside. In this way, it also causes the heat flow to carry bubbles to flow into the inner water area, and then continue to surge upward in the inner water area. Eventually, the bubbles and the boiling water will still gather at the bottom of the stew pot, causing the stew pot to vibrate. Therefore, the noise reduction effect is not ideal. Summary of the Utility Model

[0006] The utility model provides a water-separated stew pot to solve the problems that when the heating device heats water, the surging bubbles and boiling water will gather at the bottom of the inner pot, collide with the inner pot, and the disturbed water flow impacts the inner pot, causing the inner pot to vibrate and generate noise.

[0007] The technical solution adopted by the utility model is as follows:

[0008] A water-separated stew pot includes an outer pot with a water storage cavity and an inner pot placed in the water storage cavity. A heating device is arranged below the inner pot. The inner pot has a bottom wall, and support ribs are provided on the bottom wall. The water-separated stew pot further includes a heating area arranged on the outer peripheral side of the water storage cavity. The heating device is arranged in the heating area. A bubble blocking part is arranged on one side of the heating device, and the bubble blocking part is located outside the downward projection of the support ribs.

[0009] The water-separated stew pot of the utility model further has the following additional technical features:

[0010] The bottom wall of the water storage cavity is provided with a heating groove corresponding to the heating area and a convex platform inside the heating groove. The side wall of the convex platform forms the bubble blocking part. The heating device is located in the heating groove, and the distance from the bottom wall to the top of the convex platform is less than the distance from the bottom wall to the heating device.

[0011] The bottom wall of the water storage cavity is provided with an upward protruding annular rib to form the bubble blocking part, and the heating area is located outside the annular rib.

[0012] The inner pot includes a bottom wall, a side wall, and an arc section between the bottom wall and the side wall. At least part of the upward projection of the heating device is located in the arc section.

[0013] There is a flow-through gap between at least one side of the heating device and the inner wall of the heating area.

[0014] The water-separated stew pot further includes a bubble-breaking part. The bubble-breaking part and the bottom wall of the water storage cavity cooperate to form the heating area, and the bubble-breaking part is provided with bubble-breaking holes corresponding to the heating area.

[0015] The bubble-breaking part has a separating rib protruding downward. The separating rib is located on the side of the heating device close to the center of the water storage cavity to form the bubble blocking part.

[0016] There is a through gap between the separating rib and the bottom wall of the water storage cavity; or, an over-flow port is provided at the lower end of the separating rib.

[0017] There is a water storage space between the side wall of the inner pot and the inner wall of the water storage cavity, and the upward projection of the bubble-breaking holes is located in the water storage space.

[0018] A support structure for supporting the inner pot is provided on the rim of the outer pot or the side wall of the water storage cavity. The inner pot cooperates with the support structure so that there is a flow gap between the bottom wall and the bottom wall of the water storage cavity.

[0019] Due to the adoption of the above technical solution, the beneficial effects obtained by the present utility model are as follows:

[0020] 1. In the present utility model, the support ribs on the bottom wall of the inner pot divide the bottom of the inner pot into an inner region and an outer region. The heating device is arranged in the heating area on the outer peripheral side of the water storage cavity and corresponds to the outer region. When the heating device works, it preferentially heats the water in the heating area on the outer peripheral side. And a bubble blocking part is arranged on one side of the heating device, so that the water in the heating area is blocked by the bubble blocking part and cannot flow towards the center. The bubble blocking part is at least located at the bottom of the water storage cavity. Due to the blocking of the bubble blocking part, bubbles and steam will not enter the water area at the center of the water storage cavity at least during the generation and the initial stage of upward surging, thereby reducing the situation that a large number of bubbles gather in the inner region at the bottom of the inner pot, and greatly reducing the vibration of the inner pot caused by the pushing of bubbles and steam and the water flow convection between the center and the outer peripheral regions of the inner pot. Even if the water in the central water area and the outer peripheral water area in the upper water area is mixed, and a small amount of bubbles enter the central water area, but at this time, the temperature difference between the water flows in the central water area and the outer peripheral water area has relatively decreased, and the kinetic energy of the steam and bubbles has also weakened, so that the convection of the cold and hot water flows is relatively gentle, and the impact force of the water flow on the inner pot is greatly reduced. Thereby effectively reducing the noise generated during cooking and improving the use experience.

[0021] 2. As a preferred embodiment of the present utility model, the bottom wall of the water storage cavity is provided with a heating groove corresponding to the heating area and a convex platform located inside the heating groove. The side wall of the convex platform constitutes the bubble blocking part. The heating device is located in the heating groove, and the distance from the bottom wall to the top of the convex platform is less than the distance from the bottom wall to the heating device. By arranging a convex platform at the position corresponding to the inner region of the inner pot support rib, the heating area is arranged in a sunken manner relative to the convex platform, so that the installation position of the heating device is not higher than the top surface of the convex platform. In this way, the bubbles and steam generated by the heating of the water in the heating groove will flow upward under the guidance of the side wall of the heating groove, and at the same time, they are blocked by the side wall of the sunken platform, making it more difficult for the bubbles to enter the lower space at the center of the inner pot. And the sunken heating groove also makes the position of the heating device lower. The water in the water storage cavity will preferentially flow into the heating groove and will not accumulate at the convex platform. Therefore, even when the amount of water in the water storage cavity is small, it can still ensure that there is water for heating in the heating area, avoiding dry burning of the heating device and improving the service life of the heating device. In addition, since the distance between the bottom wall and the top of the convex platform is less than the distance between the bottom wall and the heating device, the water pressure in the central water area is greater than the water pressure in the outer peripheral water area. Therefore, the steam and bubbles in the outer peripheral water area are less likely to flow towards the central water area and are located in the water area outside the support rib.

[0022] 3. As a preferred embodiment of the present utility model, the inner pot includes a bottom wall, a side wall, and an arc section located between the bottom wall and the side wall. At least a part of the upward projection of the heating device is located in the arc section. At least a part of the bubbles in the heating area surge upward and will contact the arc section. The arc section can guide the bubbles, so that the bubbles and steam are guided upward by the arc surface of the arc section and continue to flow upward. As a result, the bubbles and steam float upward along the side wall of the inner pot on the outside of the inner pot more, reducing the situation that the bubbles flow into the central water area of the inner pot, so as to further avoid the accumulation of bubbles and steam in the central water area at the bottom of the inner pot, and reducing the risk of vibration of the inner pot caused by water flow disturbance.

[0023] 4. As a preferred embodiment of the present utility model, the water-separated stew pot further includes a bubble-breaking member. The bubble-breaking member and the bottom wall of the water storage cavity cooperate to form a heating area. The area of the bubble-breaking member corresponding to the heating area is provided with bubble-breaking holes. The bubble-breaking member covers the heating area inside. When the water in the heating area is heated, the generated bubbles are concentrated inside the bubble-breaking member. When the water flow in the heating area flows out through the bubble-breaking holes, it is squeezed by the bubble-breaking holes, and large-volume bubbles can be dispersed into multiple small-volume bubbles, thereby reducing the volume of the bubbles. The noise generated when small-volume bubbles burst or collide is significantly lower than that of large-volume bubbles. Therefore, the noise generated when the bubbles burst can be reduced. At the same time, the surging speed of small-volume bubbles is faster, and when they are dispersed by the extrusion of the bubble-breaking holes, they can obtain a certain kinetic energy, and then can accelerate the rapid upward surging of small bubbles to the outside of the inner pot, reducing the probability of bubbles flowing to the inner side and the water area below the center of the inner pot.

[0024] 5. As a preferred embodiment of the present utility model, a support structure for supporting the inner pot is provided on the mouth edge of the outer pot or the side wall of the water storage cavity. The inner pot cooperates with the support structure so that there is a flow gap between the bottom wall and the bottom wall of the water storage cavity. By providing a support structure on the mouth edge of the outer pot or the side wall of the water storage cavity to support the inner pot, the bottom of the inner pot is in a "suspended" state relative to the bottom wall of the water storage cavity, and the two are not in contact. As a result, the water flow in the central water area and the peripheral side water area below the inner pot can flow above the bubble barrier through the flow gap between the two, so that the inner pot will not hinder the water flow, which helps the water in the central water area and the peripheral side water area to exchange heat, making the heat distribution more uniform, and thus improving the heating uniformity of each area of the inner pot. In addition, due to the blocking of the bubble barrier at the bottom of the water storage cavity, the central water area and the peripheral side water area can only communicate above the bubble barrier. Furthermore, it helps to form a thermal convection above the bubble barrier. The hot water in the peripheral side water area flows towards the center, and the cold water in the central water area flows towards the outside. Then a regular convection is formed, which helps to squeeze the bubbles and accelerate their rupture, thereby further reducing the noise. Description of the Drawings

[0044] As Figure 1 , Figure 3 shown, a water-separated slow cooker includes an outer pot 1 having a water storage cavity 11 and an inner pot 2 placed in the water storage cavity 11. A heating device 3 is arranged below the inner pot 2. The inner pot 2 has a bottom wall 23, and support ribs 22 are provided on the bottom wall 23. The water-separated slow cooker further includes a heating area 27 provided on the outer peripheral side of the water storage cavity 11. The heating device 3 is arranged in the heating area 27. A bubble blocking part 4 is arranged on one side of the heating device 3, and the bubble blocking part 4 is located outside the downward projection of the support ribs 22.

[0045] It should be noted that, in this application, taking the heat transfer medium contained in the water storage cavity 11 as water as an example, the solution of this application is described in detail. However, this application does not limit the specific type of the heat transfer medium in the water storage cavity 11, and the technical terms of this application do not constitute a limitation on the heat transfer medium either. As long as it is a fluid and can transfer the heat of the heating device 3 to the inner pot.

[0046] This application does not limit the installation position of the heating device 3. For example, as Figure 1 , Figure 2 shown, the heating device 3 can be arranged in the water storage cavity 11, at the bottom of the water storage cavity 11 and on the outer peripheral side of the water storage cavity 11, so as to directly contact the water in the water storage cavity 11 for heating, shorten the heat transfer path and improve the heat transfer efficiency. Of course, the heating device 3 can also be arranged outside the water storage cavity 11. For example, the heating device 3 is fixed on the outer side of the bottom wall of the water storage cavity 11 or surrounds the outer side of the side wall of the outer pot 1, and contacts the outer wall of the water storage cavity 11 for heat transfer, so that the heat of the heating device 3 is first transferred to the cavity wall of the water storage cavity 11, and then transferred to the water in the water storage cavity 11. This is not limited herein. That is to say, the heating area 27 can be located inside the water storage cavity 11 or outside the water storage cavity 11.

[0047] Preferably, as Figure 2 shown, the heating device 3 is of an annular structure, and the bubble blocking part 4 is located on the side of the heating device 3 close to the center of the water storage cavity 11.

[0048] It should be noted that this application does not limit the number of the inner pots 2. It can be one as shown in the figure, or the water-bath cooker can be equipped with multiple inner pots 2 to be able to stew multiple ingredients simultaneously.

[0049] In the present utility model, the support ribs 22 on the bottom wall 23 of the inner liner 2 divide the bottom of the inner liner 2 into an inner region and an outer region. The heating device 3 is arranged in the heating area 27 on the outer peripheral side of the water storage cavity 11 and is correspondingly located in the outer region. When the heating device 3 operates, it preferentially heats the water in the heating area 27 on the outer peripheral side. One side of the heating device 3 is provided with a bubble blocking part 4, so that the water in the heating area 27 is blocked by the bubble blocking part 4 and cannot flow towards the center. The bubble blocking member is at least located at the bottom of the water storage cavity 11. Due to the blockage of the bubble blocking part 4, bubbles and steam will not enter the water area at the center of the water storage cavity 11 at least in the initial stage of generation and upward surging, thereby reducing the situation where a large number of bubbles gather in the inner region at the bottom of the inner liner 2, and greatly reducing the vibration of the inner liner 2 caused by the pushing of bubbles and steam and the water flow convection between the center and the outer peripheral region of the inner liner 2. Even if the water in the central water area and the outer peripheral water area in the upper water area is mixed, and a small amount of bubbles enter the central water area, at this time, the temperature difference between the water flows in the central water area and the outer peripheral water area has relatively decreased, and the kinetic energy of the steam and bubbles has also weakened, so that the convection of the cold and hot water flows is relatively gentle, and the impact force of the water flow on the inner liner 2 is greatly reduced. Thereby effectively reducing the noise generated during cooking and improving the user experience.

[0050] Preferably, the bubble blocking part 4 extends upward from the bottom wall of the water storage cavity 11, and the heating device 3 is located on one side of the bubble blocking member, so that the heat is concentrated on one side of the bubble blocking member, that is, one side of the bubble blocking member is the area where steam and bubbles are concentratedly generated, and is the initial stage of the upward surging of bubbles and steam. Therefore, the bubble blocking member can effectively block the violently tumbling and surging bubbles and steam here, limit them outside the bubble blocking member, and will not enter the central water area here, that is, the water area below the inner region of the support ribs 22 of the inner liner 2. However, it should be noted that the present utility model does not limit the upward extension position of the bubble blocking member and the positional relationship with the bottom wall 23 of the inner liner 2. In a preferred embodiment, as Figure 1 、 Figure 3 shown, there is a gap between the bubble blocking member and the bottom wall 23.

[0051] As Figure 1As shown, the heating zone 27 is located within the outer peripheral side water area. The central water area and the outer peripheral side water area within the water storage cavity 11 are separated at the bottom by a bubble barrier, while the central water area and the outer peripheral side water area communicate above the bubble barrier. On the one hand, this enables the bubble barrier to effectively block the violently tumbling bubbles and steam at the heating device 3, restricting them to the outside of the bubble barrier and preventing them from entering the central water area at the bottom of the water storage cavity 11. On the other hand, it allows the central water area and the outer peripheral side water area to communicate above the bubble barrier. At this time, the kinetic energy of the upward surging bubbles and steam has been greatly reduced. Even if a small number of bubbles flow towards the central water area, they will not cause irregular disturbances to the water flow, nor will they accumulate in large quantities at the center of the bottom of the inner pot 2, ensuring the noise reduction effect. In addition, it helps to form a cold and hot convection above the bubble barrier. The hot water in the outer peripheral side water area flows towards the center, and the cold water in the central water area flows towards the outside, thereby forming a regular convection, which helps to squeeze the bubbles and accelerate their rupture, further reducing the noise. It also helps the water in the central water area and the outer peripheral side water area to undergo cold and hot exchange, making the heat distribution more uniform, and thus improving the heating uniformity of each area of the inner pot 2.

[0052] Specifically, as Figure 1 shown, a support structure for supporting the inner pot 2 is provided at the rim of the outer pot 1 or the side wall of the water storage cavity 11. The inner pot 2 cooperates with the support structure so that there is a flow gap 29 between the bottom wall 23 and the bottom wall of the water storage cavity 11.

[0053] By providing a support structure at the rim of the outer pot 1 or the side wall of the water storage cavity 11 to support the inner pot 2, the bottom of the inner pot 2 is in a "suspended" state relative to the bottom wall of the water storage cavity 11, and the two are not in contact. Thus, the water flow in the central water area and the outer peripheral side water area below the inner pot 2 can flow above the bubble barrier through the flow gap 29 between the two, preventing the inner pot 2 from obstructing the water flow.

[0054] Furthermore, as Figure 1 shown, the flanging 21 at the rim of the inner pot 2 can be rested on the rim of the outer pot 1 to achieve mouth support. Or a support structure is provided on the side wall of the outer pot 1, and a matching structure is correspondingly provided on the side wall 24 of the inner pot 2 to achieve side support.

[0055] In another embodiment, the top of the bubble barrier contacts the bottom wall 23 to better separate the central water area and the outer peripheral side water area, enabling more bubbles and steam to flow in the water area outside the bubble barrier and further reducing the bubbles and steam entering the central water area inside the bubble barrier.

[0056] In this embodiment, the central water area and the peripheral water area can be completely isolated by a bubble barrier to prevent them from being connected. Alternatively, holes can be provided in the bubble barrier to connect the central water area and the peripheral water area, enabling heat exchange between the waters on both sides of the bubble barrier, reducing the temperature difference between the two sides of the water area, and thus making the heating of the central and peripheral regions of the inner tank 2 more uniform.

[0057] It should be noted that the present utility model does not limit the structure and formation method of the bubble barrier, and it can be at least one of the following embodiments:

[0058] Embodiment 1: In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 shown, a heating groove 271 corresponding to the heating area 27 and a boss 26 located inside the heating groove 271 are provided on the bottom wall of the water storage cavity 11. The side wall of the boss 26 constitutes the bubble barrier portion 4. The heating device 3 is located in the heating groove 271, and the distance from the bottom wall 23 to the top of the boss 26 is less than the distance from the bottom wall 23 to the heating device 3.

[0059] By providing a boss 26 at a position corresponding to the inner side area of the support rib 22 of the inner tank 2 and setting the heating area 27 to sink relative to the boss 26, the installation position of the heating device 3 is not higher than the top surface of the boss 26. In this way, the bubbles and steam generated by the heating of the water in the heating groove 271 will flow upward under the guidance of the side wall of the heating groove 271 and are blocked by the side wall of the boss 26 at the same time, making it more difficult for the bubbles to enter the lower space in the center of the inner tank 2. Moreover, the sunken heating groove 271 also makes the position of the heating device 3 lower. The water in the water storage cavity 11 will preferentially flow into the heating groove 271 instead of accumulating at the boss 26. Therefore, even when the water volume in the water storage cavity 11 is small, it can still ensure that there is water for heating in the heating area 27, avoiding dry burning of the heating device 3 and improving the service life of the heating device 3.

[0060] In addition, since the distance between the bottom wall 23 and the top of the boss 26 is less than the distance between the bottom wall 23 and the heating device 3, the water pressure in the central water area is greater than that in the peripheral water area. Therefore, the steam and bubbles in the peripheral water area are less likely to flow into the central water area and are located in the water area outside the support rib 22.

[0061] Embodiment 2: In this embodiment, an upwardly protruding annular rib is provided on the bottom wall of the water storage cavity 11 to form the bubble barrier portion 4, and the heating area 27 is located outside the annular rib.

[0062] Embodiment 3: In this embodiment, the water-separated slow cooker further includes a partition member. The partition member is disposed on the outer peripheral side region of the bottom of the water storage cavity 11 to cooperate with the bottom wall of the water storage cavity 11 to form a heating zone 27. The partition member has a rib protruding downward, and the rib constitutes a bubble blocking portion 4.

[0063] By using a separate component to cooperate with the bottom wall of the water storage cavity 11 to form the heating zone 27, the partition member can be separately processed and manufactured without being formed on the outer pot 1, thereby reducing the processing difficulty. Moreover, the partition member can be designed as a structure that can be detached from the outer pot 1, enabling the user to clean the partition member and preventing scale from accumulating in the heating zone 27 and affecting the heating efficiency.

[0064] It should be noted that in the above Embodiment 2 and Embodiment 3, the inner and outer waters of the bubble blocking member can be communicated by providing an opening on the bubble blocking portion 4 or by forming a gap between the bubble blocking member and the inner wall of the water storage cavity 11. On the one hand, this makes the heat distribution more uniform. On the other hand, when the water volume in the water storage cavity 11 is small, water can be timely replenished to the heating zone 27, thereby preventing the heating device 3 from dry burning.

[0065] Preferably, as Figure 4 shown, there is a flow-through gap 31 between at least one side of the heating device 3 and the inner wall of the heating zone 27. The setting of the flow-through gap 31 not only enables the water in the heating zone 27 to surround the heating device 3, increasing the contact area between the water and the heating device 3 and improving the heat exchange efficiency, but also prevents the heating device 3 from transferring too much heat to the central water area through contact with the bubble blocking member, resulting in too high a temperature in the central water area and forming a large number of bubbles and steam in the central water area.

[0066] Specifically, the heating zone 27 is surrounded by the inner wall of the water storage cavity 11 or other components. It is sufficient that there is a flow-through gap 31 between at least one side (such as the upper side, lower side, inner side, outer side) of the heating device 3 and the water storage cavity 11 or other components used to surround the heating zone 27. Preferably, there are flow-through gaps 31 between the upper, lower, left, and right sides of the heating device 3 and the inner wall of the heating zone 27.

[0067] Specifically, in a specific embodiment under the above Embodiment 1, as Figure 1 、 Figure 3 、 Figure 4 shown, the heating zone 27 is located in a heating groove 271. The side wall of the convex platform 26, the bottom wall of the heating groove 271, and the side wall of the heating groove 271 cooperate to surround the heating zone 27. There is a flow-through gap 31 between the heating device 3 and the convex platform 26 to prevent the heating device 3 from transferring too much heat to the convex platform 26.

[0068] In the second embodiment described above, the annular rib, the bottom wall of the water storage cavity 11, and the side wall of the water storage cavity 11 cooperate to form a heating area 27, and there is an overcurrent gap 31 between the heating device 3 and at least one of the three.

[0069] In the third embodiment described above, the partition member is located above the heating area 27 and cooperates with the retaining rib, the bottom wall of the water storage cavity 11, and the side wall of the water storage cavity 11 (or the outer side wall of the partition member) to form the heating area 27, surrounding the heating device 3 in all directions of up, down, left, and right, and there is an overcurrent gap 31 between the heating device 3 and at least one side thereof.

[0070] As a preferred embodiment of the present utility model, as Figure 1 shown, the inner pot 2 includes a bottom wall 23, a side wall 24, and an arc section 25 located between the bottom wall 23 and the side wall 24. At least a part of the upward projection of the heating device 3 is located in the arc section 25.

[0071] At least some of the bubbles in the heating area 27 surging upward will contact the arc section 25. The support rib 22 is located inside the arc section 25 and can block the bubbles and steam, restricting their flow towards the central water area. The arc section 25 can guide the bubbles, causing the bubbles and steam to continue to flow upward under the upward guidance of the arc surface of the arc section 25, so that the bubbles and steam float upward along the side wall 24 of the inner pot 2 more on the outside of the inner pot 2, reducing the situation of bubbles flowing into the central water area of the inner pot 2, further avoiding the accumulation of bubbles and steam in the central water area at the bottom of the inner pot 2, and reducing the risk of vibration of the inner pot 2 caused by water flow disturbance.

[0072] Specifically, as Figure 1 shown, there is a water storage space 28 between the side wall 24 of the inner pot 2 and the side wall of the outer pot 1. Part of the upward projection of the heating area 27 is located in the arc section 25, and part is located in the water storage space 28.

[0073] In a preferred embodiment, as Figures 3 to 7 shown, the slow cooker further includes a bubble-breaking member 5. The bubble-breaking member 5 and the bottom wall of the water storage cavity 11 cooperate to form the heating area 27, and the bubble-breaking holes 51 are opened in the area of the bubble-breaking member 5 corresponding to the heating area 27.

[0074] The bubble-breaking member 5 covers the heating area 27 inside. When the water in the heating area 27 is heated, the generated bubbles are concentrated inside the bubble-breaking member 5. When the water flow in the heating area 27 flows out through the bubble-breaking holes 51, it is squeezed by the bubble-breaking holes 51, enabling large-volume bubbles to be dispersed into multiple small-volume bubbles, thereby reducing the volume of the bubbles. The noise generated when small-volume bubbles burst or collide is significantly lower than that of large-volume bubbles. Therefore, the noise generated when the bubbles burst can be reduced. At the same time, the surging speed of small-volume bubbles is faster, and when they are dispersed by the extrusion of the bubble-breaking holes 51, they can obtain a certain kinetic energy, thereby accelerating the rapid upward surging of the small bubbles to the outside of the inner tank 2 and reducing the probability of the bubbles flowing inward to the water area below the inside of the support ribs 22.

[0075] In one embodiment, as Figure 3 、 Figure 4 shown, a heating groove 271 is provided on the outer peripheral side of the bottom wall of the water storage cavity 11 to form the heating area 27. A convex platform 26 is provided inside the heating groove 271, and the bubble-breaking member 5 covers the heating groove 271. Preferably, the bubble-breaking member 5 is further provided with a positioning rib 52 protruding downward for plugging and positioning with the heating groove 271. As Figure 3 、 Figure 7 shown, the bubble-breaking member 5 is an annular structure with a through hole 54 in the center. The through hole 54 corresponds to the convex platform 26, so that the convex platform 26 can directly contact the water in the central water area to heat it, improving the heat transfer efficiency.

[0076] In another embodiment, as Figure 5 shown, the bubble-breaking member 5 has a partition rib 53 protruding downward. The partition rib 53 is located on the side of the heating device 3 close to the center of the water storage cavity 11 to form a bubble blocking portion 4.

[0077] The bubble-breaking member 5 is used to cooperate with the inner wall of the water storage cavity 11 to form the heating area 27, can also disperse large bubbles by squeezing them through the bubble-breaking holes 51, and further forms a bubble blocking portion 4 to block the bubbles. Thus, the bubble-breaking member 5 realizes the integration of multiple functions, simplifies the overall structure of the slow cooker, and saves costs.

[0078] Furthermore, as Figure 3 、 Figure 6 shown, there is a water storage space 28 between the side wall 24 of the inner tank 2 and the inner wall of the water storage cavity 11. The upward projection of the bubble-breaking hole 51 is located in the water storage space 28.

[0079] The bubble-breaking hole 51 corresponds to the water storage space 28, so that after the bubbles are discharged through the bubble-breaking hole 51, they directly surge upward into the water storage space 28. Therefore, during the rising process of the bubbles and steam, they will not directly impact the bottom of the inner tank 2, and thus the inner tank 2 will not vibrate.

[0080] Preferably, there is a through-gap between the partition rib 53 and the bottom wall of the water storage chamber 11; alternatively, a water flow port is provided at the lower end of the partition rib 53.

[0081] Through the setting of the through-gap or the water flow port, the central water area and the water area of the heating zone 27 are connected, so that the water in the two sides can exchange heat, reducing the temperature difference between the two sides of the water, so that the center and the peripheral area of the inner tank 2 are heated more evenly. And the connection position is at the lower end of the partition rib 53, so that when the water volume in the water storage chamber 11 is insufficient, the water in the central water area can also enter the heating zone 27, thus preventing the heating device 3 from dry burning.

[0082] What is not described in the present invention can be realized by adopting or referring to the existing technology.

[0083] Each embodiment in this specification is described in a progressive manner. For the same or similar parts among the embodiments, reference can be made to each other. Each embodiment focuses on the differences from other embodiments.

[0084] The above are only the embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various modifications and changes can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
