The temperature sensor is used for detecting the temperature in the inner container 4. The temperature sensor may be provided on the cover 3, or the temperature sensor may be provided on the casing 2 or the liner 4.

The operation panel is provided on the upper side of the cover 3. The user can set various parameters of the rice to be cooked through the control panel and select an operation mode of the cooking apparatus 1. Parameters of the rice to be cooked include the kind and quantity of the rice to be cooked. The operating modes may include a first operating mode and a second operating mode. The first operating mode is used for fully automatically cooking low-sugar rice and the second operating mode is used for semi-automatically cooking low-sugar rice.

The control unit 10 is a logic control unit of the cooking device 1, and the control unit 10 may be a programmable logic controller or other microcomputer. The control unit 10 is electrically connected to the rice supply assembly 6, the water delivery assembly 7, the sensing assembly 8, the heating assembly 9, and the operation panel through cables. Specifically, the control unit 10 is electrically connected to the reversing valve 74 of the water delivery assembly 7, the driving means of the water pump 75 and the telescopic mechanism 72, the conveyor of the rice supply assembly 6, the pressure sensor 81 of the detection assembly 8, and the temperature sensor.

As shown in fig. 8, the present embodiment also proposes a control method of the cooking apparatus, which is implemented by the control unit 10 operating the respective execution parts of the cooking apparatus 1.

The control method comprises the following steps: the control unit 10 drives the heating component 9 to heat the inner container 4 filled with rice and water, and the water in the inner container 4 is at least heated to boiling; the control unit 10 drives the water delivery assembly 7 to discharge water with at least part of sugar dissolved in the inner container 4; the control unit 10 drives the heating assembly 9 to heat the inner container 4 to cook the rice before or after driving the water delivery assembly 7 to discharge water at least a portion of which is dissolved with sugar in the inner container 4.

After the water in the inner container 4 is heated to boiling, sugar on rice is more easily dissolved into the boiling water to separate from rice grains, then after part of water dissolved in the inner container 4 is discharged out of the inner container 4, the total sugar content in the inner container 4 is reduced, and finally, the rice is cooked to obtain low-sugar rice, and the sugar content of the low-sugar rice is lower than that of common rice.

The low-sugar rice is cooked by adopting the cooking device 1, and the rice, the cooking water and the inner container are contacted with each other, so that the problems of rice clamping or wet and rotten rice bottom and side edges of the cooked low-sugar rice caused by the factors of water quantity, power, plateau environment and the like can be avoided.

In an exemplary embodiment, as shown in fig. 8, a specific control method is proposed, which includes the steps of:

step S100: the control unit 10 drives the heating component 9 to heat the inner container 4 filled with rice and water, so that the water in the inner container 4 continuously boils for a first preset time period, and the step S200 is carried out;

the heating component 9 heats the inner container 4, the water temperature in the inner container 4 rises, and after the water in the inner container 4 boils, the inner container 4 is continuously heated by the heating component 6 to maintain the boiling state for a first preset period of time.

During the boiling of the water in the inner container 4, the boiling water continuously washes the rice, so that sugar on the rice can be fully dissolved into the boiling water. The sugar includes a reducing sugar.

The first preset time period is configured to be less than a time required for the rice to cook in boiling water. I.e. the rice cannot be cooked after the water in the inner container 4 starts to boil and then undergoes boiling for a first preset period of time. The first preset time period is preferably less than 15 minutes, i.e. the time for boiling of the water does not exceed 15 minutes. The beneficial effects are that: 1. finally, the cooked rice of the low-sugar rice has clear particles and better mouthfeel; 2. the rice soup formed by this water is not thick and the risk of clogging the pipe is very small when this water is subsequently discharged out of the liner 4 through the pipe.

In this step, the heating power of the heating assembly 9 to heat the water from the non-boiling state to the boiling state is greater than the heating power of the heating assembly 9 to maintain the water in the boiling state. Namely, the heating component 9 heats the inner container 4 with the heating power P1 to boil water in the inner container 4, and then heats the inner container 4 with the heating power P2 to maintain the boiling state of the water, wherein P1 is more than or equal to P2. The water in the liner 4 is heated by the higher heating power P1, so that the water can be quickly boiled, and the time is saved; the water in the liner 4 is kept boiling by the lower power P2, so that the electric power can be saved, and the overflow of the pot caused by long-time high-power heating can be prevented.

Step S200: the control unit 10 drives the water delivery assembly 7 to discharge part of water with sugar dissolved in the liner 4;

the control unit 10 drives the telescopic mechanism 72 to extend, and the second end 722 extends towards the bottom of the liner 4 in the extending process of the telescopic mechanism 72 until the second end 722 abuts against the bottom wall of the liner 4. Since the inlet and outlet 731 of the delivery pipe 73 is disposed at the second end 722, the second end 722 is abutted against the bottom wall of the inner container 4, so that the inlet and outlet 731 is immersed in water, and then the control unit 10 drives the reversing valve 74 to communicate the water pump 75 with the sewage chamber 712, and drives the water pump 75 to reverse rotation, so that the water in the inner container 4 is sucked from the inlet and outlet 731 of the delivery pipe 73 and pumped into the sewage chamber 712 by the water pump 75, and the water is discharged out of the inner container 4.

In this step, only a part of the water in the liner 4 is discharged, and a part of the sugar is discharged to the liner 4 together with the part of the water, so that the total sugar content in the liner 4 is reduced. A portion of the water, which is less than fifty percent of the amount of water required to cook the same amount of rice in the inner container 4 into ordinary rice, may be 20 to 400g, for example, is retained in the inner container 4 for cooking the rice.

Step S300: the control unit 10 drives the heating assembly 9 to heat the inner container 4 to cook the rice.

The control unit 10 cooks the rice into low sugar rice by heating the water remaining in the inner container 4, the total sugar content of the low sugar rice being lower than that of ordinary rice.

In an exemplary embodiment, as shown in fig. 9, another specific control method is also proposed, which specifically includes the following steps:

step S100a: the control unit 10 drives the heating component 9 to heat the inner container 4 filled with rice and water, so that the water in the inner container 4 continuously boils for a first preset time period, and the step S200 a is carried out;

During the boiling of the water in the inner container 4, the boiling water continuously washes the rice, so that sugar on the rice can be fully dissolved into the boiling water.

Step S200a: the control unit 10 drives the water delivery assembly 7 to discharge all water dissolved with sugar out of the inner container 4;

In this step, all the water in the liner 4 is drained, and sugar dissolved in the water is drained out of the liner 4 along with the water, so that the total sugar content in the liner 4 is lower.

Step S300a: the control unit 10 drives the water delivery assembly 7 to inject water into the liner 4, and the step S400a is performed;

in this step, the water injected into the inner container 4 is used to cook rice. The kind and the amount of the rice in the inner container 4 are inputted into the control unit 10 through the operation panel in advance by the user. The cooking water quantity is the water quantity required for cooking rice. The amount of cooking water corresponds to the amount of rice, and generally the larger the amount of rice, the greater the amount of cooking water needed. The amount of cooking water needed is not necessarily the same when the amounts of rice are the same. The control unit 10 pre-stores the corresponding relationship between the kind and the amount of the rice and the cooking water amount, and obtains the corresponding cooking water amount according to the kind and the amount of the rice. The corresponding relation between the type and the amount of rice and the cooking water amount can be measured through multiple tests.

The cooking apparatus 1 of the present embodiment is used to cook low sugar rice in a much smaller amount of water than is required to cook ordinary rice. The cooking water amount is less than fifty percent of the water amount required for cooking the same amount of rice in the inner container 4 into common rice, and may be 20 to 400g, for example.

When water is injected, the control unit 10 drives the reversing valve 74 to connect the water pump 75 with the clean water cavity 711, and drives the water pump 75 to inject the water in the clean water cavity 711 into the inner container 4 according to the cooking water quantity through the inlet and outlet 731 of the conveying pipe 73.

The control unit 10 measures the first total weight of the inner container 4 and the carried articles thereof through the pressure sensor 81 of the detection assembly 8 before the water delivery assembly 7 is filled with water, then calculates the sum of the first total weight and the cooking water to obtain the second total weight, and when the pressure sensor 81 measures that the total weight of the inner container 4 and the carried articles reaches the second total weight in the process of filling the water into the inner container 4 by the water delivery assembly 7, the control unit 10 controls the water delivery assembly 7 to stop filling the water into the inner container 4. Thus, the cooking water amount is precisely injected into the inner container 4.

Step S400a: the control unit 10 drives the heating assembly 9 to heat the inner container 4 to cook the rice.

The heating component 9 heats the inner container 4 to cook the rice into low-sugar rice, and the cooking temperature and the cooking time of the cooked rice can be calibrated in advance. The control unit 10 can cook according to the preset cooking temperature and cooking time in the process of driving the heating assembly 9 to heat the inner container 4 to cook rice.

In this embodiment, the control unit 10 drives the water delivery assembly 7 to fill water into the liner 4 to reduce the temperature in the liner 4 until the temperature in the liner 4 is reduced to below 65 ℃.

In an exemplary embodiment, as shown in fig. 10, another specific control method is also proposed, which includes the following steps:

step S100b: the control unit 10 drives the heating component 9 to heat the inner container 4 filled with rice and water so that the water in the inner container 4 boils and evaporates until the water in the inner container 4 is burnt out, and the step S200b is carried out;

the heating component 9 heats the inner container 4, the water temperature in the inner container 4 is increased, after the water in the inner container 4 is boiled, the inner container 4 is continuously heated by the heating component 6 to evaporate part of the water, and the rest of the water is absorbed by rice.

During the boiling of the water in the inner container 4, the boiling water continuously washes out the rice, so that sugar on the rice is analyzed, no flowing water exists in the inner container 4 after the water in the inner container 4 is boiled, and the rice is partially gelatinized.

Step S200b: the control unit 10 drives the water delivery assembly 7 to inject water into the inner container 4, and then drives the water delivery assembly 7 to discharge water in the inner container 4 out of the inner container 4, and the step S300b is performed;

when water is injected, the control unit 10 drives the reversing valve 74 to connect the water pump 75 with the clean water cavity 711, and drives the water pump 75 to inject water in the clean water cavity 711 into the liner 4 through the inlet and outlet 731 of the conveying pipe 73. The amount of water to be injected may be a constant value or may be increased as the amount of rice in the inner container 4 increases.

During drainage, the control unit 10 drives the telescopic mechanism 72 to extend, and the second end 722 extends towards the bottom of the liner 4 in the extending process of the telescopic mechanism 72 until the second end 722 abuts against the bottom wall of the liner 4. Since the inlet and outlet 731 of the delivery pipe 73 is disposed at the second end 722, the second end 722 is abutted against the bottom wall of the inner container 4, so that the inlet and outlet 731 is immersed in water, and then the control unit 10 drives the reversing valve 74 to communicate the water pump 75 with the sewage chamber 712, and drives the water pump 75 to reverse rotation, so that the water in the inner container 4 is sucked from the inlet and outlet 731 of the delivery pipe 73 and pumped into the sewage chamber 712 by the water pump 75, and the water is discharged out of the inner container 4.

In this step, cold water having a temperature lower than 30 ℃ may be injected into the inner container 4, and after the water is injected into the inner container 4, sugar separated from rice is dissolved into water and then discharged out of the inner container 4 along with the water, thereby reducing the total sugar content in the inner container 4. At the same time, these water can carry away the heat of the partially gelatinized rice, causing the temperature of the partially gelatinized rice to drop, so that a portion of the starch in the rice is converted into resistant starch.

The temperature of the boiled water in the inner container 4 is very high, and after the water delivery assembly 7 injects water into the inner container 4, the water temperature in the inner container 4 is reduced, so that the water temperature is reduced to be within the temperature resistant range of parts such as pipelines, and the service lives of the parts can be prolonged by discharging the water in the inner container 4 out of the inner container 4. Therefore, the high temperature resistant requirement of parts such as pipelines is reduced, and the manufacturing cost is reduced.

Step S300b: the control unit 10 drives the water delivery assembly 7 to inject water into the liner 4, and the step S400b is performed;

the control unit 10 drives the reversing valve 74 to connect the water pump 75 with the clean water chamber 711, and then drives the water pump 75 to inject water in the clean water chamber 711 into the liner 4 through the inlet and outlet 731 of the conveying pipe 73.

In this step, the water injected into the inner container 4 is used for cooking rice, and the water injection amount is less than fifty percent of the water required for cooking the same amount of rice in the inner container 4 into ordinary rice, for example, 20 to 400g.

Step S400b: the control unit 10 drives the heating assembly 9 to heat the inner container 4 to cook the rice.

The control unit 10 cooks rice into low sugar rice by heating water in the inner container 4, the total sugar content of the low sugar rice being lower than that of ordinary rice. At the same time, the content of resistant starch of the low-sugar rice is increased, and the resistant starch is difficult to digest, cannot be digested in the small intestine, is digested slowly in vivo and is absorbed and enters blood slowly. Thus, the starch in the rice is more difficult to digest and absorb.

In an exemplary embodiment, step S200b is performed a plurality of times, i.e., the control unit 10 drives the water delivery assembly 7 to alternately fill the inside of the inner container 4 and drain the water inside the inner container 4 out of the inner container 4 a plurality of times.

The sugar can be more thoroughly washed out of the inner container 4 by alternately injecting water into the inner container 4 and discharging water in the inner container 4 out of the inner container 4 for a plurality of times. At the same time, the temperature of the rice in the inner container 4 can be reduced to be lower, and the content of resistant starch in the rice can be increased to be higher.

The control unit 10 drives the water delivery assembly 7 to alternately inject water into the inner container 4 and discharge water in the inner container 4 out of the inner container 4 more than 10 times.

In an exemplary embodiment, as shown in fig. 11, the cooking device 1 further comprises a stirring device 5. The stirring device 5 is electrically connected to the control unit 10 by means of a cable. The stirring device 5 includes a driving motor 51 and a stirring member 52. The driving motor 51 is fixed to the inner container 4. The body of the driving motor 51 may be disposed outside the inner container 4 and fixed to the bottom wall of the inner container 4. The stirring member 52 is provided in the inner container 4, and the stirring member 52 may be a bottom wall close to the inner container 4. The inner container is provided with a shaft hole which penetrates through the wall surface of the inner container. The shaft hole may be provided in the bottom wall of the inner container. The main shaft of the driving motor 51 passes through the shaft hole on the inner container and is connected with the stirring piece 52. The driving motor 51 can drive the stirring member 52 to rotate. A shaft seal may be provided between the shaft hole and the main shaft of the driving motor 51 to prevent water in the inner container 4 from leaking from the shaft hole.

The step S200b further includes: after the control unit 10 drives the water delivery assembly 7 to inject water into the inner container 4 and before the control unit 10 drives the water delivery assembly 7 to discharge water in the inner container 4 out of the inner container 4, the control unit 10 also drives the stirring device 5 to stir the water and rice in the inner container 4.

When stirring rice and water, stirring device 5 can make sugar in rice fully dissolve into rice, further improves the sugar reduction effect.

In an exemplary embodiment, the main axis of the drive motor 51 is perpendicular to the bottom wall of the liner 4. The stirring member 52 is constructed in a rod-like structure, which may be a straight rod. The extending direction of the stirring member 52 is perpendicular to the main shaft of the driving motor 51.

The driving motor 51 can drive the stirring member 52 to rotate along the direction approximately parallel to the bottom wall of the inner container 4, the extending direction of the stirring member 52 is parallel to the bottom wall of the inner container 4, the stirring range of the stirring member 52 is large, rice and water at the bottom of the inner container 4 can be sufficiently stirred, and the stirring member 52 is very simple in structure and low in cost.

In an exemplary embodiment, the spindle of the drive motor 51 is arranged coaxially with the bottom wall of the inner container 4. When the stirring member 52 stirs the rice and water in the inner container 4, the rice and water in the inner container 4 can be rotated around the axis of the inner container 4, and the stirring resistance of the stirring member 52 can be smaller.

In an exemplary embodiment, another specific control method is also presented, which includes steps S100 c-S200 c.

Step S100c: the control unit 10 drives the heating component 9 to heat the inner container 4 filled with rice and water so as to boil the water, and after the water boils, the control unit continues to drive the heating component 9 to heat the inner container 4 until the rice in the inner container 4 is boiled, and the step S200c is carried out;

the heating component 9 heats the inner container 4, the water temperature in the inner container 4 is increased, and after the water in the inner container 4 boils, the inner container 4 is continuously heated by the heating component 6 until the rice is cooked, and the rice is completely gelatinized when the rice is cooked.

Step S200c: the control unit 10 drives the water delivery assembly 7 to inject water into the inner container 4, and then drives the water delivery assembly 7 to discharge water in the inner container 4 out of the inner container 4;

In this step, water of a preset water temperature is injected into the liner 4, and the preset temperature has a value range of more than 50 ℃ and less than 70 ℃. Namely, the water injected into the liner 4 by the water delivery assembly 7 is driven to be warm water. After water is injected into the inner container 4, sugar separated out from rice is dissolved into water, and then is discharged out of the inner container 4 along with the water, so that the total sugar content in the inner container 4 is reduced. At the same time, these water can carry away a portion of the heat of the fully gelatinized rice, causing the temperature of the fully gelatinized rice to drop, such that a portion of the starch in the rice is converted to resistant starch.

Thus, the total sugar content of the low sugar rice in the liner 4 after draining is lower than that of ordinary rice. At the same time, the content of resistant starch of the low-sugar rice is increased, and the resistant starch is difficult to digest, cannot be digested in the small intestine, is digested slowly in vivo and is absorbed and enters blood slowly. Thus, the starch in the rice is more difficult to digest and absorb. Meanwhile, rice grains are cooked at the beginning, so that the rice is kept in a fully cooked state, and the rice has good taste and does not pinch.

The step S200c further includes: after the control unit 10 drives the water delivery assembly 7 to inject water into the inner container 4 and before the control unit 10 drives the water delivery assembly 7 to discharge water in the inner container 4 out of the inner container 4, the control unit 10 also drives the stirring device 5 to stir the water and rice in the inner container 4.

When stirring rice and water, stirring device 5 can make sugar in rice fully dissolve into rice, further improves the sugar reduction effect. The number of times the stirring device 5 stirs the rice and the water is preferably not less than 30 times.

In an exemplary embodiment, step S200c is performed a plurality of times, i.e., the control unit 10 drives the water delivery assembly 7 to alternately fill the inside of the inner container 4 and drain the water inside the inner container 4 out of the inner container 4 a plurality of times.

The sugar can be more thoroughly washed out of the inner container 4 by alternately injecting water into the inner container 4 and discharging water in the inner container 4 out of the inner container 4 for a plurality of times. At the same time, the content of resistant starch in the rice can be raised higher.

The control unit 10 drives the water delivery assembly 7 to alternately inject water into the inner container 4 and discharge water in the inner container 4 out of the inner container 4 less than 10 times, preferably 2 times.

In an exemplary embodiment, the rice is heated, rolled or puffed to break the rice before being added to the liner 4.

The dried rice is heated at 180-280 ℃ for more than or equal to 2 minutes, so that cracks can be generated on the rice. Rolling the dried rice may also cause cracks to develop in the rice. The rice is puffed under the conditions of high temperature and high pressure, and cracks are generated on the puffed rice.

When the rice with cracks is soaked in water, water can enter the cracks of the rice, the contact area of the water and the rice is larger, the water absorption speed of the rice can be accelerated, the dissolution of soluble sugar is accelerated, and the total sugar content of the low-sugar rice is reduced more favorably.

In an exemplary embodiment, as shown in fig. 8, the control method further includes steps S10 to S30, and steps S10 to S30 are performed before heating the water in the inner container 4 to boiling.

Step S10: the control unit 10 obtains the information of the set working mode, and judges whether the set working mode is the first working mode, if yes, the step S10 is entered, otherwise, the step of heating the liner 4 by the heating assembly is entered, for example, step S100a, step S100b or step S100c;

in the first operation mode, the cooking device 1 automatically adds rice and water for soaking rice into the inner container 4, manual intervention is not needed, and the cooking device 1 can automatically cook low-sugar rice.

In the second operation mode, the user puts the rice and the water for soaking the rice into the inner container 4 in advance, inputs the amount of the rice through the operation panel, and finally the cooking device 1 performs steps S110 to S130 to cook the low-sugar rice.

S20: the control unit 10 drives the rice supply assembly 6 to input the preset amount of rice into the inner container 4, and the step S30 is performed;

After the cooking device 1 is started in the first operation mode, the control unit 10 drives the conveyor of the rice supply assembly 6 to input the rice, which may be, for example, pearl rice, in a set amount into the inner container 4 in the rice bin 61.

S30: the control unit 10 drives the water delivery assembly 7 to inject water with preset water quantity into the inner container 4 to soak the rice in the inner container 4, and the step S100 is performed;

when water is injected, the control unit 10 drives the reversing valve 74 to connect the water pump 75 with the clean water cavity 711, and drives the water pump 75 to inject water in the clean water cavity 711 into the liner 4 through the inlet and outlet 731 of the conveying pipe 73 according to a preset water amount, for example, 200-1000 g. The preset water quantity can be a fixed value or can be increased along with the increase of the set quantity of rice.

In this step, the control unit 10 measures the third total weight of the liner 4 and the articles carried by the liner 4 through the pressure sensor 81 of the detection assembly 8 before the water is injected into the liner 4, and calculates the sum of the third total weight and the preset water amount to obtain the fourth total weight, and when the pressure sensor 81 measures that the total weight of the liner 4 and the articles carried by the liner 4 reaches the fourth total weight in the process of injecting water into the liner 4 through the water delivery assembly 7, the control unit 10 controls the water delivery assembly 7 to stop injecting water into the liner 4. Thus, a predetermined amount of water is precisely injected into the inner container 4.

step S100d: the control unit 10 drives the heating component 9 to heat the inner container 4 filled with rice and water until the water is boiled, and then the heating is continued to enable the water to be boiled for a first preset time, wherein the quality of the water in the inner container (4) is the preset sugar dissolving water amount, and the step S200b is carried out;

the preset sugar-dissolving water amount is smaller than the water amount required for cooking the same amount of rice in the inner container 4 into common rice, i.e. the preset sugar-dissolving water amount is relatively smaller. The preset sugar-dissolving water quantity is matched with the component of the rice in the inner container 4, and can be positively correlated with the component of the rice in the inner container 4. The preset sugar dissolving water amount can be 200-600 g.

During the boiling of the water in the inner container 4, the boiling water continuously washes the rice, so that sugar on the rice can be fully dissolved into the boiling water. Because the water with smaller preset sugar dissolving water quantity is added in the inner container 4 in advance, the rolling force of the water is larger when the water is boiled, and each rice grain can roll and dissolve sugar in the rice grains as much as possible.

In this step, the heating power of the heating assembly 9 to heat the water from the non-boiling state to the boiling state and the heating power of the heating assembly 9 to maintain the water in the boiling state are both greater than one third of the maximum heating power of the heating assembly (9). Under the condition that less water is arranged in the inner container 4 and the inner container 4 is heated by adopting larger heating power, the water is boiled more severely, so that the rolling force of the rice grains is larger, and sugar in the rice grains is more fully dissolved.

Step S200d: the control unit 10 drives the water delivery assembly 7 to inject water into the inner container 4, and then drives the water delivery assembly 7 to discharge water in the inner container 4 out of the inner container 4, and the step S300d is performed;

Step S300d: the control unit 10 drives the water delivery assembly 7 to inject water into the liner 4, and the step S400d is performed;

Step S400d: the control unit 10 drives the heating assembly 9 to heat the inner container 4 to cook the rice.

In an exemplary embodiment, step S200d is performed a plurality of times, i.e., the control unit 10 drives the water delivery assembly 7 to alternately fill the inside of the inner container 4 and drain the water inside the inner container 4 out of the inner container 4 a plurality of times.

In one exemplary embodiment, as shown in fig. 2 and 6, retraction mechanism 72 includes a plurality of piston cylinders 725, cylinder heads 724, and cylinder 723. The cylinder 723 is configured in a cylindrical shape. A cylinder head 724 is capped on one end of the cylinder 723. The cylinder head 724 and the cylinder 723 are fixed in the mounting cavity of the cover body 3, and the cylinder head 724 is positioned at the bottom of the mounting cavity. A pressure inlet port may be provided in head 724 or cylinder 723.

Piston cylinder 725 includes a cylinder body 726 and piston rings 727. The cylinder body 726 is configured in a cylindrical shape, and a piston ring 727 is fitted around the cylinder body 726 and fixes one end of the cylinder body 726. A limiting groove 728 can be arranged on the peripheral wall of the cylinder body 726, and the limiting groove 728 is annular and coaxial with the cylinder body 726. The inner edge of the piston ring 727 is embedded into the limiting groove 728, and the outer edge of the piston ring 727 extends out of the limiting groove 728.

The diameters of the plurality of piston cylinders 725 increase in sequence. A plurality of piston cylinders 725 are nested together in sequence. The adjacent two pistons can slide relatively. The piston ring 727 of the smaller diameter piston cylinder 725 of the adjacent two piston cylinders 725 abuts against the inner peripheral surface of the cylinder body 726 of the larger diameter piston cylinder 725. Piston rings 727 seal the gap between adjacent two piston cylinders 725. Cylinder 723 is fitted over piston cylinder 725 having the largest diameter, and piston ring 727 of piston cylinder 725 abuts against the inner peripheral wall of cylinder 723.

As shown in fig. 7, the cooking apparatus 1 further includes a power source 70. The power source 70 is connected to a cylinder head 724 or a pressure inlet hole on a cylinder 723 through a pipe. The power source 70 may inject a fluid, which may be a gas or a liquid, into the intake aperture. After the fluid is injected into the cylinder 723, the pressure in the cylinder 723 increases, pushing the piston cylinder 725 to slide toward the bottom side of the liner 4, thereby realizing the extension of the expansion mechanism 72. In this embodiment, the power source 70 is an air pump. The inlet and outlet 731 of the delivery pipe 73 is provided at one end of the cylinder body 726 of the piston cylinder 725 having the smallest diameter, which is directed toward the bottom of the inner container 4. When the expansion mechanism 72 expands, the cylinder body 726 of the piston cylinder 725 having the smallest diameter abuts against the bottom of the liner 4.

In one illustrative embodiment, the delivery tube 73 is disposed within the telescoping mechanism 72. The inner side of the cylinder head 724 is provided with a water pipe joint 7241. The end of the delivery pipe 73 facing away from the inlet and outlet 731 is fitted over a water pipe joint 7241, and the water pipe joint 7241 is also connected to the water pump 75. Both ends of the conveying pipe 73 are fixed to the first end 721 and the second end 722 of the telescopic mechanism 72, respectively.

The delivery tube 73 is disposed within the telescoping mechanism 72, and the telescoping mechanism 72 can protect the delivery tube 73. And simultaneously, the exposed parts are reduced, and the cleaning difficulty is reduced. The length of the delivery tube 73 is greater than the length of the telescopic mechanism 72 in the extended state so that the delivery tube 73 does not obstruct the extension of the telescopic mechanism 72.

In one illustrative embodiment, the delivery tube 73 extends in a spiral. The delivery tube 73 preferably extends in a cylindrical helical line.

The transport pipe 73 has a structure similar to that of a coil spring, and the transport pipe 73 is also elastic and can be elastically deformed by stretching. The conveying pipe 73 is not stretched only when the telescopic mechanism 72 is in the shortened state. When the telescopic mechanism 72 is extended, the delivery pipe 73 is pulled, and the delivery pipe 73 applies an elastic force to the piston cylinder 725 having the smallest diameter toward the cover 3.

In this way, when the power source 70 drives the expansion mechanism 72 to extend, the hydraulic pressure or the pneumatic pressure is stopped, and the delivery pipe 73 applies an elastic force to the piston cylinder 725 toward the cover 3, so that the expansion mechanism 72 is shortened.
