There is a conflict between eating habits and healthy eating concepts. Rice is the main ingredient of Chinese people's daily diet. The main ingredient is starch. The rice cooked in a general rice cooker has a high sugar content and is not suitable for daily consumption by people with high blood sugar. There are currently two types of sugar-free rice cookers. One can discharge the liquid in the inner pot to the bottom of the inner pot or outside the rice cooker to achieve the purpose of lowering blood sugar, but this type of rice cooker requires additional space to store the discharged liquid, which increases the volume of the rice cooker; the other type has a mesh auxiliary pot that can move up and down in the inner pot. The rice is in the auxiliary pot. The existence of the auxiliary pot will hinder the boiling and rolling of the water. The rice in the auxiliary pot cannot fully roll, resulting in uneven heating, affecting the quality of the rice. Summary of the invention

Detailed implementation manners

[0023] The following further describes the implementation manners of the present invention in detail with reference to the drawings and reference numerals, so that those skilled in the art can implement it after studying this specification. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] The present invention provides a sugar - removing rice cooker as Figure 1 shown, which includes an inner liner 1 and a cover body 2 covering the opening of the inner liner 1. An exhaust port 21 is provided on the cover body 2. It further includes an auxiliary liner 3. The auxiliary liner 3 is placed in the inner liner 1 and a closed cavity is formed between the auxiliary liner 3 and the inner liner 1. The auxiliary liner 3 is provided with a drain pipe 31. One end of the drain pipe 31 is inside the auxiliary liner 3 and is provided with a drain port 314, and the other end extends to the bottom of the inner liner 1 and is provided with a filter screen 311; A plug 221 for closing the drain port is provided on the drain port, and the cover body 2 is provided with a lifting device 22 for raising the plug 221.

[0025] The inner pot, the lid, and the auxiliary pot are all independent components, and the inner pot and the auxiliary pot can be taken out of the rice cooker. The auxiliary pot is placed inside the inner pot, enclosing a sealed cavity between them. When the lid completely covers the inner pot, it presses the auxiliary pot and the inner pot tightly to ensure airtightness. The auxiliary pot is provided with a drain pipe extending vertically, connecting the inner pot and the auxiliary pot. One end of the drain pipe is a drain opening, located inside the auxiliary pot, maintaining a certain distance from the bottom of the auxiliary pot, so that the liquid that can be stored in the auxiliary pot will not enter the drain opening; the other end of the drain pipe extends to the bottom of the inner pot and is provided with a filter screen. The filter screen has multiple filter holes that can block rice grains while allowing liquid to pass through, and the filter screen can protrude towards the inner pot side to form an arc-shaped spherical surface, as Figure 1 shown, which can spread the rice grains around, preventing the rice grains from getting stuck at the bottom of the filter screen, resulting in the improper placement of the auxiliary pot and affecting airtightness. A plug is provided at the drain opening. One end of the plug in contact with the drain opening can be conical. In the natural state, the conical end of the plug extends into the drain opening, and it can seal the drain opening by its own gravity. The lid is also provided with a lifting device, which is connected to the plug and can raise the position of the plug to open the drain opening. The auxiliary pot, the drain pipe, and the filter screen can be made of aluminum alloy material, and the plug can be made of 304 stainless steel.

[0026] When the present invention is in use, the mixture of rice and water can be first placed in the inner pot, and then the auxiliary pot is put into the inner pot. The lid is closed to make the space between the auxiliary pot and the inner pot airtight. The liquid level in the inner pot is much higher than the filter screen at the bottom of the drain pipe. When cooking rice, the temperature rises, causing a part of the sugar in the rice to transfer into the water. The water is heated to generate water vapor, continuously increasing the internal pressure of the cavity enclosed by the inner pot and the auxiliary pot, with a tendency to press the liquid out of the drain pipe. However, the plug seals the drain pipe, inhibiting the generation of this tendency. The space between the auxiliary pot and the lid is connected to the outside through the exhaust port, creating a pressure difference between the inside and outside of the auxiliary pot. In one embodiment, this pressure difference ≤ 100 kPa. When sugar removal is required, the lifting device is used to raise the plug away from the drain opening, releasing the pressure. The mixed liquid in the inner pot is pushed by the pressure difference to flow out through the drain pipe into the auxiliary pot, forming a by-product, while the rice grains are blocked by the filter screen and remain in the inner pot to be steamed and cooked, thus completing sugar removal.

[0027] Preferably, the lifting device 22 includes a vertical rod 222. The lid 2 is provided with a first sleeve 23. The vertical rod 222 and the first sleeve 23 are slidably connected. The first sleeve 23 is provided with a seal 4 on the contact surface with the vertical rod 222. One end of the vertical rod 222 is connected to the plug 221, and the other end is provided with a magnetic induction member 223. An electromagnet 224 is provided at the top of the lid 2 at the position corresponding to the magnetic induction member 223.

[0028] As Figure 1As shown, in one embodiment, the lifting device includes a vertical rod, one end of which is connected to the plug, and the other end is provided with a magnetic induction member; the vertical rod is slidably connected to the first sleeve provided on the cover body, which plays a positioning role; the sealing member can be an O-ring made of silicone to prevent moisture from corroding the relevant parts of the electromagnet; an electromagnet corresponding to the position of the magnetic induction member is also provided on the top of the cover body, and when the electromagnet is energized, the position of the plug can be lifted by the magnetic induction member to open the drain port. The vertical rod can be made of stainless steel, the magnetic induction member can be made of ferromagnetic material into a disc shape, and the electromagnet can be a CJKT type small electromagnet.

[0029] Preferably, a trumpet-shaped liquid guide plate 312 with a larger upper part and a smaller lower part is provided on the drain port, a convex ring 3121 is provided on the top of the liquid guide plate 312, a first sealing gasket 313 is provided on the convex ring 3121, the first sealing gasket 313 and the liquid guide plate 312 form a liquid drainage cavity, and a plurality of drain ports 314 are provided at the bottom of the liquid guide plate 312; a conical head 2211 is provided on the side of the plug 221 facing the liquid guide plate 312.

[0030] like Figure 2 As shown, in one embodiment, in order to prevent the mixed liquid from being sprayed onto the cover body from the liquid discharge port, a liquid guide plate and a first sealing gasket are provided on the liquid discharge port. The liquid guide plate can be a trumpet-shaped plate that is larger at the top and smaller at the bottom, and a convex ring is provided on the top edge thereof, and a first sealing gasket is provided on the convex ring, so that a liquid discharge cavity for the mixed liquid to pass through is formed between the sealing ring and the liquid guide plate, and a plurality of liquid discharge ports are also provided at the bottom of the liquid guide plate, and the outlet direction of the liquid discharge port can be tilted downward. A conical head is provided on the side of the plug facing the liquid guide plate, and the conical head can press the first sealing gasket against the top of the liquid discharge pipe by its own weight, so that the top of the liquid discharge pipe is sealed. When the plug is lifted by the lifting device, the mixed liquid flows to the top of the liquid discharge pipe under the action of the pressure difference, is blocked by the first sealing gasket and changes direction, and flows out from the liquid discharge port to the auxiliary gallbladder through the liquid discharge cavity, and its outflow direction changes from toward the cover body to toward the auxiliary gallbladder. The liquid guide plate, convex ring and conical head can be made of aluminum alloy; the first sealing gasket is a flexible silicone sealing ring, which is safe, non-toxic and deformable. When the plug is pressed down, it can increase the air tightness between the plug and the discharge port. When the plug rises, the first sealing gasket can be stretched open by pressure to allow the mixed liquid to pass through.

[0031] Preferably, the plurality of drain ports 314 are arranged on the side wall at the top of the drain pipe 31; a sealing groove 2212 is provided on the side of the plug 221 facing the drain port 314, the sealing groove 2212 is slidably connected to the drain pipe 31, and a second sealing gasket 2213 is provided on the inner wall of the sealing groove 2212.

[0032] like Figure 3As shown, in one embodiment, a plurality of drain ports are provided on the side wall of the top of the drain pipe, and the outlet direction of the drain port can be inclined downward. A sealing groove is provided on the side of the plug facing the drain port. The sealing groove is slidably connected to the drain pipe and is used to open and seal the drain port. A second gasket is provided on the inner wall of the sealing groove to increase the airtightness between the sealing groove and the drain pipe. When the plug is pressed downward, the sealing groove can completely seal the drain port; when the plug is lifted, the sealing groove moves upward to expose the drain port. The second gasket can be a silicone gasket.

[0033] Preferably, a liquid accumulation pit 11 is provided at the bottom of the inner container 1, and the drain pipe 31 extends to the bottom of the liquid accumulation pit 11; support feet 12 are provided at the bottom of the inner container 1.

[0034] The vertical height from the bottom end of the drain pipe and the filter screen to the bottom of the inner container determines the retention amount of the mixed liquid, which directly affects the sugar removal amount. When the liquid level of the mixed liquid drops to the filter screen, the air inside and outside the secondary container is connected, and the drain pipe can no longer discharge the mixed liquid. The liquid accumulation pit minimizes the liquid level of the mixed liquid. The drain pipe extends to the bottom of the liquid accumulation pit, and the filter screen can be lowered below the bottom surface of the inner container, enabling the mixed liquid to be emptied as much as possible and improving the sugar removal effect.

[0035] The support feet can be made of heat-insulating and heat-resistant materials such as calcium silicate. Specifically, the support feet can be annular or at least three feet evenly distributed at the bottom of the inner container. When the inner container with the liquid accumulation pit is taken out and placed on a flat surface, the support feet are used to maintain balance and prevent the inner container from tilting.

[0036] Preferably, the lifting device 22 is a telescopic device 225; the secondary container 3 is provided with a second sleeve 35. The second sleeve 35 is slidably connected to the drain pipe 31. A limiting plate 315 is provided on the drain pipe 31. A compression spring 36 is provided between the limiting plate 315 and the second sleeve 35. A first liquid leakage port 351 is provided on the second sleeve 35, and a second liquid leakage port 316 is provided on the drain pipe 31; a sealing ring 317 extending downward is provided on the limiting plate 315, and the sealing ring 317 is slidably connected to the second sleeve 35.

[0037] As Figure 6 and Figure 7 shown, in one embodiment, the secondary container is further provided with a component for flowing the liquid in the secondary container into the inner container. In existing rice cookers with a reservation cooking function, it is necessary to put the mixture of water and rice into the inner container in advance, but long-term soaking will affect the taste of the rice. The water can be put into the secondary container, and when cooking is required, the water is flowed into the inner container to avoid the above problems.

[0038] Specifically, a second sleeve is provided on the auxiliary gallbladder, the second sleeve is slidably connected to the drainage pipe, a first liquid leakage port is provided on the second sleeve, and a second liquid leakage port is provided on the drainage pipe; a limit plate is also provided on the drainage pipe at a position higher than the second sleeve, and a compression spring is provided between the limit plate and the second sleeve, and when the compression spring is in a reset state, the second liquid leakage port is higher than the first liquid leakage port, and the two are staggered. The lifting device is a telescopic device connected to the plug, which can not only lift the plug, but also lower the position of the plug. When the liquid in the auxiliary gallbladder needs to flow into the inner tank, the telescopic device is controlled to drive the plug downward, so that the first liquid leakage port is aligned with the second liquid leakage port, forming a channel so that the liquid in the auxiliary gallbladder flows into the inner tank through this channel and the drainage pipe, and at the same time the compression spring is compressed to store elastic potential energy. After the liquid completely enters the inner tank, the telescopic device drives the plug back to its original position, and the compression spring releases the elastic potential energy, moves the drainage pipe upward, and staggers the first liquid leakage port and the second liquid leakage port. Furthermore, the liquid accumulation pit at the bottom of the inner tank has a margin for the drainage pipe to descend.

[0039] The limit plate and the second sleeve can be made of aluminum alloy, and are respectively integrally formed with the drainage pipe and the auxiliary gallbladder; the compression spring can be made of 65Mn spring steel. In order to prevent the spring from being corroded by the liquid, the limit plate is also provided with a downwardly extending sealing ring, which is slidably connected with the second sleeve to seal the compression spring inside. The sealing ring can be integrally formed with the limit plate; a silicone sealing layer is provided on the inner wall of the sealing ring and the contact surface of the drainage pipe with the second sleeve to increase the airtightness. Both the first leakage port and the second leakage port are provided in plurality, and the two are equal in number and matched in position. The telescopic device can adopt an electric telescopic rod, which can accurately control the telescopic stroke.

[0040] Preferably, it further comprises a control system, wherein the control system comprises a timer, and the timer is connected to the electromagnet signal.

[0041] The timer can be a 555 type timer, which is connected to the electromagnet signal to control the start and stop of the electromagnet, and is used to control the discharge timing and discharge duration of the mixed liquid in the inner tank.

[0042] Preferably, an anti-blocking net is provided at the bottom of the drain pipe 31 to wrap the filter screen 311 .

[0043] like Figure 4 As shown, further, a second layer of slightly larger anti-blocking net can be set at the bottom of the drain pipe and outside the filter screen to protect the filter screen and prevent the rice grains from completely blocking the smaller filter screen after being heated and softened. The anti-blocking net can be a spherical steel wire mesh with a filter hole smaller than the rice grains.

[0044] Preferably, the side wall of the auxiliary gallbladder 3 is provided with a recessed installation groove, and a safety valve 34 is provided in the installation groove.

[0045] likeFigure 1 As shown, the safety valve can adopt a micro spring type safety valve, which is hermetically connected to the secondary bladder. Its critical pressure value is 175 - 200 kPa. The gas can only pass unidirectionally. When the critical pressure value is exceeded, it will automatically exhaust gas, preventing the internal pressure in the cavity between the secondary bladder and the inner bladder from being too high and reducing the safety risk. Specifically, a vertically extending installation groove can be provided on the side wall of the secondary bladder to vertically install the safety valve.

[0046] Preferably, a circular groove 13 is provided at the top of the inner bladder 1, and a convex edge 32 extending outward is provided at the top of the secondary bladder 3. The groove 13 and the convex edge 32 are in clearance fit, and a first sealing ring 5 is provided on the groove 13; a second sealing ring 6 is provided between the cover body and the secondary bladder.

[0047] As Figure 5 shown, a circular groove is provided at the top edge of the inner bladder, and a convex edge is provided at the top of the secondary bladder. The groove and the convex edge are in clearance fit, so that the secondary bladder can be placed inside the inner bladder. A first sealing ring is provided on the groove to increase the airtightness between the secondary bladder and the inner bladder. A second sealing ring is provided between the secondary bladder and the cover body. The second sealing ring can fill the gap between the cover body and the secondary bladder, so that the cover body can transfer the pressure to the secondary bladder after being tightened, further increasing the airtightness between the secondary bladder and the inner bladder. The second sealing ring can be connected to the cover body. The first and second sealing rings can be made of silica gel.

[0048] The above are one or more embodiments of the present invention, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
