A self-replenishing stew pot

Abstract

This utility model discloses a stew pot that can replenish broth automatically, including: an outer shell, an inner pot, a lid, and an injection assembly. The inner pot has a cavity for holding broth. The injection assembly includes a flexible guide tube, a sleeve, a micro pump, an outlet pipe connected to the micro pump, and an inlet pipe. The flexible guide tube is fixed to the upper part of the inner pot and sleeved on the upper end of the sleeve. The sleeve is connected to the outlet pipe of the micro pump, and the inlet pipe of the micro pump is connected to the supply end of purified water. The micro pump slowly pumps water from the supply end of purified water upwards. The water slowly flows into the inner pot through the sleeve and the flexible guide tube, and then flows into the guide channel.

Description

Technical Field

[0001] This utility model relates to the field of home appliance technology, and in particular to a stew pot that can replenish soup automatically. Background Technology

[0002] When stewing food in a slow cooker, a lot of water often evaporates and is lost due to prolonged stewing time or stewing with the lid off, resulting in too little broth or too thick broth. It may even cause the food to stick to the bottom of the pot. Therefore, it is necessary to add an appropriate amount of water to replenish the broth in the slow cooker when stewing for too long or stewing with the lid off.

[0003] When using existing slow cookers with water-adding functions, if you need to add broth to the slow cooker, you usually pour a large amount of water directly into the slow cooker quickly. Adding a large amount of water quickly will cause some of the protein in the food to coagulate, preventing some substances in the food from being extracted into the broth, thus ruining the original flavor of the broth. In addition, the water added is not heated and comes into direct contact with the food, which will change the texture of the food. For example, the meat fibers on the surface of meat will shrink quickly, causing the meat to become dry and tough. Summary of the Invention

[0004] To overcome the shortcomings of the existing technology, the purpose of this utility model is to propose a stew pot that can replenish soup automatically, so as to solve the problem that when replenishing soup in existing stew pots, a large amount of unheated water is directly and quickly added into the stew pot, which causes damage to the taste of the ingredients and soup.

[0005] A self-replenishing stew pot includes: an outer shell, an inner pot, a lid, and an injection assembly. The inner pot has a cavity for containing soup. The injection assembly includes a flexible guide tube, a sleeve, a micro pump, an outlet pipe connected to the micro pump, and an inlet pipe. The flexible guide tube is fixed to the upper part of the inner pot and sleeved on the upper end of the sleeve. The sleeve is connected to the outlet pipe of the micro pump to connect the inside of the inner pot and the outlet pipe of the micro pump. The inlet pipe of the micro pump is connected to a purified water supply end.

[0006] Preferably, the stew pot that can replenish soup itself also includes a flow guiding component, which includes a flow guiding ring that contacts the inner wall of the inner pot. The flow guiding ring has an inclined flow guiding groove, the inlet end of which is connected to the outlet end of the flexible flow guiding pipe, and the outlet end of which is connected to the cavity of the inner pot.

[0007] Preferably, there may be several guide rings, and each guide groove has a drain outlet at its outlet end. In two adjacent guide grooves, the drain outlet of the upper guide groove is connected to the inlet end of the lower guide groove.

[0008] Preferably, the flow guiding component further includes protruding blocks, with several protruding blocks protruding upward in each flow guiding groove. The protruding blocks are evenly distributed in the flow guiding groove, and the protrusion height of the protruding blocks is lower than the depth of the flow guiding groove.

[0009] Preferably, the flexible guide tube further includes a magnetic block one, which is fixed to one end of the flexible guide tube near the sleeve. The sleeve further includes a magnetic block two, which is fixed to one end of the sleeve near the flexible guide tube. When the flexible guide tube and the sleeve are in contact, the magnetic block one is magnetically attracted to the magnetic block two.

[0010] Preferably, the casing further includes a receiving ring, the upper end of which is open, and the lower end of which is connected to the interior of the casing. The opening at the upper end of the receiving ring is larger than the opening at the upper end of the casing.

[0011] Preferably, the stew pot that can replenish soup itself also includes an evaporation detection component, which includes a pressure sensor and a support plate. The pressure sensor is fixedly attached to the outer shell, and the support plate is fixedly attached to the detection end of the pressure sensor. The inner pot is placed on the support plate.

[0012] Preferably, the opening of the flexible guide tube away from the sleeve is angled downwards.

[0013] Preferably, the outer edge of the guide channel is lower than the inner edge of the guide channel, the protrusion height of the convex block is higher than the outer edge of the guide channel and lower than the upper edge of the inner edge of the guide channel, and the outer edge of the guide channel is in contact with the inner wall of the inner liner.

[0014] Beneficial effects: 1. When the inner pot is placed in, the flexible guide tube on the inner pot is slightly deformed and sleeved on the sleeve. After the food in the inner pot is heated for a certain period of time, especially after the soup in the inner pot boils, the water in the inner pot will be lost relatively quickly. The micro pump controlled by the electronic control system slowly pumps the water from the pure water supply end upward. The water slowly flows into the inner pot through the sleeve and the flexible guide tube, and then flows down along the inner wall of the inner pot. Therefore, it is not necessary to open the lid to replenish the soup in the inner pot, so as to prevent the soup in the inner pot from being too little or too viscous.

[0015] 2. When water needs to be added to the inner pot, the water slowly flows into the inner pot through the flexible guide tube. The water then flows down the inner wall of the inner pot into the guide groove. As the water flows down the guide groove, the higher temperature guide ring preheats the water in the guide groove. Then, the water in the guide groove overflows from the guide groove and flows into the food in the inner pot. This reduces the temperature difference between the added water and the food, thus preventing the food from becoming less palatable due to the low temperature of the added water. In this way, the impact on the food and broth is reduced during the replenishment process, maintaining the taste and texture of the broth and food.

[0016] 3. Water flows through the upper guide channel and then into the lower guide channel, finally flowing into the food inside the inner pot from the lowest guide channel. As the water flows through the guide channel, it is blocked by the convex baffle. When the water overflows from the upper edge of the convex baffle, it continues to flow downward, thereby further extending the heating time of the added water, further reducing the temperature difference between the added water and the food, and further protecting the taste and flavor of the food.

[0017] 4. When the inner pot is placed in the pot, the pressure sensor detects the weight of the inner pot and the food. During the stewing process, after the weight of the inner pot and the food drops by a certain value, the electronic control system controls the micro pump to replenish the inner pot. After the weight of the inner pot and the food is restored, the electronic control system controls the micro pump to stop pumping, thereby more accurately replenishing the soup.

[0030] like Figures 1-4 , Figure 6 and Figure 7As shown, a self-replenishing stew pot includes: an outer shell 10, an inner pot 20, a lid 30, and an infusion assembly 40. The outer shell 10, inner pot 20, and lid 30 are separable and combinable. The inner pot 20 has a cavity for containing soup. The infusion assembly 40 includes a flexible guide tube 41, a sleeve 42, a micro pump 43, an outlet pipe 431 connected to the micro pump 43, and an inlet pipe 432. The flexible guide tube 41 is fixed to the upper part of the inner pot 20 and is sleeved on the sleeve 42. The sleeve 42 is fixed to the outer shell 10. The sleeve 42 is connected to the outlet pipe 431 of the micro pump 43 to connect the inside of the inner liner 20 and the outlet pipe 431 of the micro pump 43. The inlet pipe 432 of the micro pump 43 is connected to the supply end of pure water. The micro pump 43 is a micro peristaltic pump that can rotate in both directions and has a diameter of about 5 cm. The pressure sensor 61 is connected to the electronic control system. The supply end of pure water is a container filled with pure water. The guide pipe that extends into the pure water is connected to the inlet pipe 432 of the micro pump 43 by a snap fastener.

[0031] The inlet pipe 432 of the micro pump 43 is connected to the supply end of purified water. When the inner pot 20 is placed inside, the flexible guide tube 41 on the inner pot 20 is slightly deformed and fits onto the sleeve 42. The flexible guide tube 41 and the sleeve 42 are pressed together. After the food in the inner pot 20 is heated for a certain period of time, especially after the soup in the inner pot 20 boils, the water in the inner pot 20 will be lost relatively quickly. At this time, a certain amount of water needs to be added to the inner pot 20, but it is necessary to avoid adding water too quickly, which will cause the temperature inside the inner pot 20 to drop rapidly, affecting the stewing efficiency of the food in the inner pot 20, and even affecting the taste and texture of the food. When water needs to be added to the inner pot 20, the micro pump 43 controlled by the electronic control system slowly pumps the water from the pure water supply end upwards. The water slowly flows into the inner pot 20 through the sleeve 42 and the flexible guide tube 41, and then flows downwards along the inner wall of the inner pot 20. This eliminates the need to open the lid to replenish the soup in the inner pot 20, preventing the soup in the inner pot 20 from being too little or too viscous. When the stewing is complete, the micro pump 43 controlled by the electronic control system reverses the flow of the small amount of pure water remaining in the flexible guide tube 41 and the sleeve 42 back to the pure water supply end. Then the inner pot 20 can be removed, and the sleeve 42 and the flexible guide tube 41 can be separated.

[0032] More preferably, such as Figure 3 and Figure 5 As shown, the stew pot that can replenish soup itself also includes a flow guiding component 50. The flow guiding component 50 includes a flow guiding ring 51, which contacts the inner wall of the inner pot 20. The flow guiding ring 51 has an inclined flow guiding groove 511. The upper inclined end of the flow guiding groove 511 is the inlet end, and the lower inclined end of the flow guiding groove 511 is the outlet end. The inlet end of the flow guiding groove 511 is connected to the water outlet end of the flexible flow guiding pipe 41, and the outlet end of the flow guiding groove 511 is connected to the cavity of the inner pot 20.

[0033] When water needs to be added to the inner pot 20, the water slowly flows into the inner pot 20 through the flexible guide pipe 41. The water then flows down the inner wall of the inner pot 20 into the guide groove 511. As the water flows down the guide groove 511, the higher temperature guide ring 51 preheats the water in the guide groove 511. Then, the water in the guide groove 511 overflows from the outlet end of the guide groove 511 and flows into the food in the inner pot 20. In this way, the temperature difference between the added water and the food is reduced, thereby avoiding the deterioration of the taste and texture of the food due to the low temperature of the added water. For example, the rapid contraction of the meat fibers on the surface of meat will make the meat dry and tough. The rapid contraction of the meat fibers will also affect the penetration of the soup into the food, resulting in the food not being flavorful. It will also affect the umami substances in the food from entering the soup, affecting the flavor of the soup. In this way, the impact on the food and soup is reduced during the process of adding soup, so as to maintain the taste and texture of the soup and food.

[0034] More preferably, such as Figure 3 and Figure 5 As shown, there may be several guide rings 51. Each guide groove 511 has a drain port 53 at its outlet end. In two adjacent guide grooves 511, the drain port 53 of the upper guide groove 511 is connected to the inlet end of the lower guide groove 511.

[0035] Water flows through the upper guide channel 511 and then through the drain outlet 53 of the upper guide channel 511 into the lower guide channel 511. Finally, it flows from the drain outlet 53 of the lower guide channel 511 into the food inside the inner liner 20. This reduces the heating time of the added water and further reduces the temperature difference between the added water and the food, thus better protecting the texture and flavor of the food.

[0036] More preferably, such as Figure 3 and Figure 5 As shown, the flow guiding assembly 50 also includes a convex block 52. Several convex blocks 52 protrude upward in each flow guiding groove 511. The several convex blocks 52 are evenly distributed in the flow guiding groove 511, and the protrusion height of the convex blocks 52 is lower than the depth of the flow guiding groove 511.

[0037] When water flows through the guide channel 511, it is blocked by the protruding block 52. After the water overflows from the upper edge of the protruding block 52, it continues to flow downward, thereby further extending the heating time of the added water, further reducing the temperature difference between the added water and the food, and further protecting the taste and flavor of the food.

[0038] More preferably, such as Figure 4 , Figure 6 and Figure 7As shown, the flexible guide tube 41 also includes a magnetic block 411, which is fixed to one end of the flexible guide tube 41 near the sleeve 42. The sleeve 42 also includes a magnetic block 421, which is fixed to one end of the sleeve 42 near the flexible guide tube 41. When the flexible guide tube 41 and the sleeve 42 are in contact, the magnetic block 411 is magnetically attracted to the magnetic block 421.

[0039] When the inner pot 20 is inserted, the flexible guide tube 41 on the inner pot 20 is slightly deformed and fits onto the sleeve 42. The magnetic block 1 411 and the magnetic block 2 421 are magnetically attracted to each other, thereby reducing the time required to align the flexible guide tube 41 and the sleeve 42. The magnetic attraction between the magnetic block 1 411 and the magnetic block 2 421 can squeeze the flexible guide tube 41 and the sleeve 42 respectively, making the flexible guide tube 41 and the sleeve 42 fit more tightly to prevent water from leaking out from between the flexible guide tube 41 and the sleeve 42. When the stewing is completed and the inner pot 20 is removed, the magnetic block 1 411 and the magnetic block 2 421 detach, and the sleeve 42 and the flexible guide tube 41 separate.

[0040] More preferably, such as Figure 3 and Figure 5 As shown, the sleeve 42 also includes a receiving ring 422, the upper end of the receiving ring 422 is open, the lower end of the receiving ring 422 is connected to the inside of the sleeve 42, and the upper end of the receiving ring 422 is larger than the upper end opening of the sleeve 42.

[0041] When the stewing is completed and the inner pot 20 is removed, the magnetic block 1 411 and the magnetic block 2 421 detach, the sleeve 42 and the flexible guide tube 41 separate, and a small amount of liquid droplets dripping from the flexible guide tube 41 will drip onto the receiving ring 422 or the sleeve 42. The liquid droplets on the receiving ring 422 flow into the sleeve 42 under its own gravity, thereby preventing the liquid droplets from falling into the heating parts of the outer shell 10.

[0042] More preferably, such as Figure 3 and Figure 6 As shown, the stew pot that can replenish soup itself also includes an evaporation detection component 60. The evaporation detection component 60 includes a pressure sensor 61 and a support plate 62. The pressure sensor 61 is fixedly connected to the outer shell 10. The pressure sensor 61 is connected to the electronic control system. The support plate 62 is fixedly connected to the detection end of the pressure sensor 61. The inner pot 20 is placed on the support plate 62.

[0043] When the inner pot 20 is placed in, the pressure sensor 61 detects the weight of the inner pot 20 and the food. During the stewing process, after the weight of the inner pot 20 and the food drops by a certain value, the micro pump 43 is controlled by the electronic control system to replenish the inner pot 20. After the weight of the inner pot 20 and the food is restored, the micro pump 43 is controlled by the electronic control system to stop pumping, so as to more accurately replenish the soup.

[0044] More preferably, such as Figure 4 , Figure 6 and Figure 7 As shown, the opening of the flexible guide tube 41 away from the sleeve 42 is set at an angle downward.

[0045] A certain amount of condensate will accumulate on the inner walls of the lid 30 and the inner pot 20. When the water above the flexible guide tube 41 flows downward, the outer wall of the flexible guide tube 41 guides the condensate to prevent it from flowing directly into the flexible guide tube 41, thereby preventing the inner wall of the flexible guide tube 41 from being contaminated to a certain extent.

[0046] More preferably, such as Figure 3 and Figure 5 As shown, the outer edge of the guide channel 511 is lower than the inner edge of the guide channel 511, the protrusion height of the convex block 52 is higher than the outer edge of the guide channel 511 and lower than the inner edge of the guide channel 511, and the outer edge of the guide channel 511 is in contact with the inner wall of the inner liner 20.

[0047] The water in the guide channel 511 can directly contact the inner wall of the inner tank 20, which is more efficient than heating the guide ring 51 first and then heating the water in the guide channel 511, thereby improving the heating efficiency of the supplementary water.

[0048] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
