Description

Technical Field

[0001] The present invention relates to the field of intelligent kitchen appliances, and in particular to a steamer. Background Art

[0002] The drainage structure of the existing digester realizes the opening and closing effect of the drain outlet by driving the valve core to move by the magnetic core after the coil is energized. The main thing is that after the coil is energized, a mutual magnetic force is generated between the valve core and the magnetic core, and the magnetic core drives the valve core to move to open the drain outlet through the magnetic force. However, there is no structure for gathering the magnetic field between the magnetic core and the coil of the existing digester, resulting in a large leakage of the magnetic field generated after the coil is energized. The magnetic field cannot be well concentrated on the magnetic core, resulting in the magnetic force of the magnetic core driving the valve core to move not being concentrated, the movement of the valve core is unstable, and it is easy to fail.

[0003] At the same time, when the valve core of the existing digester is in the state of closing the drain outlet, the valve core is completely inside the coil, and the bottom end face of the valve core is located above the bottom end face of the coil. After the coil is energized, the bottom of the coil generates a downward attractive magnetic force on the bottom end face of the valve core to prevent the valve core from moving upward, forming resistance. As a result, a larger upward vertical attractive magnetic force is required for the magnetic core to drive the valve core upward through magnetic force. In particular, at the moment when the coil is energized and started, the vertical attractive magnetic force for the magnetic core to drive the valve core upward through magnetic force needs to be very large to enable the magnetic core to drive the valve core upward. At this time, the coil needs to have a larger power and a larger number of coil turns, resulting in a higher cost of the coil, and causing the valve core to move unstably and fail easily. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems in the above-mentioned related art at least to a certain extent.

[0005] To this end, the purpose of the present invention is to provide a digester, which mainly solves the problem that after the coil of the existing digester is energized, the bottom of the coil generates a downward attractive magnetic force on the bottom end face of the valve core to prevent the valve core from moving upward, resulting in the magnetic core driving the valve core to move upward through magnetic force requiring a larger upward vertical attractive magnetic force. It mainly solves the problem that the magnetic field generated by the coil of the existing digester after energization is difficult to effectively concentrate on the magnetic core, and solves the problem that the valve core of the existing digester is unstable in movement and easy to fail.

[0006] An embodiment of the present invention provides a steamer, including an inner pot, which is installed in a pot body and is characterized in that: a drain outlet is opened on the inner pot, and a valve core is detachably installed on one side of the drain outlet, and the valve core can be moved to open and close the drain outlet; a magnetic core is installed on the upper outer portion of the valve core, and a coil is provided on the outer side of the valve core, and the magnetic core can drive the valve core to move by magnetic force; when the valve core is in the position of closing the drain outlet, the bottom end surface of the valve core extends outward by a distance H relative to the bottom end surface of the coil, and H ≥ 0 mm.

[0007] In the aforementioned steamer, when the valve core is in the position of opening the drain port, the bottom end surface of the valve core extends outwards by a distance H1 relative to the bottom end surface of the coil, where H>H1≥0mm.

[0008] In the aforementioned steamer, when the valve core is in the position of opening the drain port, the bottom end surface of the valve core retracts inwardly by a distance H2 relative to the bottom end surface of the coil, where H2>0 mm.

[0009] In the aforementioned steamer, the coil is electrically connected to the power module. When the coil is energized, the magnetic core can drive the valve core to move through magnetic force to open the drain outlet.

[0010] The aforementioned digester further includes a magnetic field collecting component, which is located outside the coil and covers at least a portion of the outer surface of the coil.

[0011] In the aforementioned digester, the magnetic field concentrating assembly includes a first magnetic field concentrating member, and the first magnetic field concentrating member at least covers a portion of the top end surface of the coil.

[0012] In the aforementioned steamer, the magnetic core is configured as a protruding structure relative to the first magnetic concentrator, and the magnetic core is located inside the coil.

[0013] In the aforementioned digester, the magnetic field focusing assembly further includes a second magnetic field focusing member, which at least covers a portion of the side surface and / or the bottom end surface of the coil.

[0014] The aforementioned digester further comprises an outer pot, and the inner pot is located inside the outer pot.

[0015] In the aforementioned steamer, one end of the coil is electrically connected to the power module through the inner pot, and / or the other end of the coil is electrically connected to the power module through the outer pot.

[0016] In the aforementioned steamer, a drainage channel is provided on the inner pot, the drainage port is located at the end of the drainage channel, and the coil is located outside the drainage channel.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This solution sets a magnetic core and a valve core so that when the coil is energized, the magnetic core can drive the valve core upward through magnetic force to open the drain port, thereby achieving the effect of draining the inner pot.

[0019] This solution is configured so that when the valve core is in the position of closing the drain outlet, the bottom end face of the valve core extends outward by a distance H relative to the bottom end face of the coil, H ≥ 0mm, so that when the coil is energized and started, the bottom end face of the valve core is flush with the bottom end face of the coil, or the bottom end face of the valve core is located below the bottom end face of the coil, thereby effectively reducing the downward magnetic force of the bottom of the coil on the bottom end face of the valve core, that is, reducing the resistance, and effectively reducing the vertical magnetic force of the magnetic core to drive the valve core upward through magnetic force, which can relatively reduce the power of the coil and the number of coil turns, resulting in lower coil cost and more stable and reliable movement of the valve core.

[0020] This solution sets up a magnetic concentrating component, which at least covers a part of the outer surface of the coil, so that the magnetic concentrating component can play a magnetic concentrating role. The first magnetic concentrating component covers at least a part of the top end surface of the coil, so that the magnetic field generated after the coil is energized can be concentrated on the magnetic core. The magnetic field can be effectively concentrated, so that the magnetic force of the magnetic core to drive the valve core to move is enhanced. The second magnetic concentrating component covers at least a part of the side surface and / or the bottom end surface of the coil, so that the second magnetic concentrating component can guide the magnetic field generated after the coil is energized and concentrate the magnetic field. The magnetic field generated by the coil has less leakage, and the magnetic field on the side surface and the bottom end surface of the coil can be effectively concentrated upward and inward under the guiding magnetic concentrating action of the second magnetic concentrating component, so that the magnetic force between the magnetic core and the valve core is enhanced when the coil is energized, and the movement of the valve core is more stable and the reliability is higher.

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0033] Embodiment: A digester of the present invention, such as Figures 1 to 10 As shown in the structure, the steamer of this scheme is provided with an outer pot 1 and an inner pot 2, and the inner pot 2 is arranged in the outer pot 1, and a drain outlet 2011 is provided on the inner pot 2. The valve core 4 is moved to realize the opening and closing effect of the drain outlet 2011, thereby realizing the water communication between the inner pot 2 and the outer pot 1, and the water in the inner pot 2 can be discharged into the outer pot 1 or the water in the outer pot 1 can enter the inner pot 2. The steamer can be used to make low-sugar food, and the water and food materials can be separated during the steaming process, which is particularly convenient for making low-sugar rice.

[0034] The steamer of this scheme has an inner pot 2 installed in the pot body 3, and a drain port 2011 is opened on the inner pot 2. A valve core 4 is detachably installed on one side of the drain port 2011. The valve core 4 can be moved to open and close the drain port 2011. The valve core 4 is mainly installed on the upper side of the drain port 2011. The valve core 4 can be independently disassembled for cleaning. The valve core 4 is directly placed on the upper side of the drain port 2011 without the need for other structures to install and fix it, so that the valve core 4 can be independently disassembled and installed; a magnetic core 6 is installed on the upper outer side of the valve core 4. A coil 5 is provided on the outside of the valve core 4, and the magnetic core 6 can drive the valve core 4 to move by magnetic force. This is mainly because after the coil 5 is energized, the magnetic core 6 inside the coil 5 and the valve core 4 absorb the magnetic field generated by the coil 5 to generate magnetic force, so that the magnetic core 6 can drive the valve core 4 to move by magnetic force; the valve core 4 closes the drain outlet 2011 mainly relying on the gravity of the valve core 4. When the coil 5 is de-energized, the valve core 4 moves downward due to its own gravity to close the drain outlet 2011. The whole process realizes the opening and closing effect of the valve core 4 on the drain outlet 2011.

[0035] When the valve core 4 is in the state of closing the drain outlet 2011, the bottom end surface of the valve core 4 extends outwardly by a distance H relative to the bottom end surface of the coil 5, and H≥0mm; including the bottom end surface of the valve core 4 being flush with the bottom end surface of the coil 5, that is, H=0, and at the same time including the bottom end surface of the valve core 4 protruding outwardly relative to the bottom end surface of the coil 5, that is, H>0; the above two situations ensure that when the valve core 4 is in the state of closing the drain outlet 2011, the bottom end surface of the valve core 4 will not retract into the coil 5 relative to the bottom end surface of the coil 5, that is, the bottom end surface of the magnetic core 6 can be located at a position flush with the bottom end surface of the coil 5 or at a position where the protrusion extends downward, which can effectively reduce the downward magnetic force generated by the bottom of the coil 5 on the bottom end surface of the valve core 4. The downward magnetic force generated by the bottom of the coil 5 on the bottom end surface of the valve core 4 is a resistance to the magnetic force of the magnetic core 6 driving the valve core 4 to move upward, thereby preventing the valve core 4 from moving upward. If the resistance is too large, the vertical magnetic force of the magnetic core 6 to drive the valve core 4 upward through magnetic force needs to be larger to drive the valve core 4 to move. This requires a larger power of the coil 5, and the corresponding number of turns of the coil 5 also needs to be more, resulting in a higher cost of the coil 5; this solution sets the bottom end face of the valve core 4 to extend outward by a distance H relative to the bottom end face of the coil 5, H≥0mm, so that the bottom end face of the valve core 4 or a part of the bottom of the valve core 4 is located outside the coil 5, and the magnetic field generated after the coil 5 is energized is difficult to concentrate on the bottom end face of the valve core 4, so that the bottom end face or a part of the bottom of the valve core 4 will not generate much magnetic force, that is, the bottom end face or a part of the bottom of the valve core 4 is not in the magnetic field of the coil 5, and will not generate much magnetic force. In this way, the resistance of the magnetic core 6 to drive the valve core 4 upward is reduced, and the vertical magnetic force of the magnetic core 6 to drive the valve core 4 upward is also smaller, so that the magnetic core 6 can drive the valve core 4 upward.

[0036] When the bottom end face of the valve core 4 extends outward by a large distance H relative to the bottom end face of the coil 5, preferably H ≥ 2mm, the bottom end face of the valve core 4 is completely outside the magnetic field of the coil 5, and the bottom of the valve core 4 will not generate magnetic force. This eliminates the problem of the bottom of the coil 5 generating a downward magnetic force to attract the bottom of the valve core 4, so that only the part of the valve core 4 located in the coil 5 generates magnetic force. The magnetic force of this part can be attracted to the magnetic force of the magnetic core 6, so that the magnetic core 6 drives the valve core 4 to move upward through the magnetic force, so that the valve core 4 opens the drain port 2011, and the magnetic force required for the magnetic core 6 to drive the valve core 4 to move upward is smaller, the power of the coil 5 is lower, the number of turns is less, and the corresponding cost of the coil 5 is also lower.

[0037] In this solution, when the valve core 4 is in the state of closing the drain outlet 2011, the bottom end face of the valve core 4 extends outwardly by a distance H relative to the bottom end face of the coil 5, and H≥0mm. After the magnetic core 6 drives the valve core 4 to move upward to open the drain outlet 2011, there are two situations for the valve core 4. One of the situations is that the bottom end face of the valve core 4 is outward relative to the bottom end face of the coil 5, that is, it extends downward by a distance, that is, the bottom end face of the valve core 4 is located outside the coil 5, or the bottom end face of the valve core 4 is flush with the bottom end face of the coil 5; the other situation is that the bottom end face of the valve core 4 is retracted inwardly relative to the bottom end face of the coil 5, that is, it extends upward by a distance, that is, the bottom end face of the coil 5 is located inside the coil 5; wherein, after the magnetic core 6 drives the valve core 4 to move upward to open the drain outlet 2011 and the bottom end face of the valve core 4 is flush with the bottom end face of the coil 5, then H>0, and when H=0, then when the magnetic core 6 drives the valve core 4 After moving upward to open the drain outlet 2011, the bottom end surface of the valve core 4 is retracted and recessed inward relative to the bottom end surface of the coil 5, that is, it extends upward by a distance; the above two situations can both reduce the downward magnetic force of the bottom of the coil 5 on the bottom end surface of the valve core 4, mainly to reduce the downward magnetic force of the bottom of the coil 5 on the bottom end surface of the valve core 4 at the moment after the coil 5 is energized, that is, to reduce the resistance of the magnetic core 6 to the valve core 4 moving upward, so the magnetic force required for the magnetic core 6 to drive the valve core 4 to move upward is smaller. When the valve core 4 is in the process of moving upward, because the distance between the top end surface of the valve core 4 and the bottom end surface of the magnetic core 6 becomes smaller and smaller, the magnetic force of the magnetic core 6 on the valve core 4 becomes larger and larger. At this time, the downward magnetic force of the bottom of the coil 5 on the bottom end surface of the valve core 4 has less and less influence on the magnetic core 6 to drive the valve core 4 to move upward, that is, the influence of the resistance on the upward movement of the valve core 4 becomes smaller and smaller.

[0038] One of the above situations, such as Figure 3 As shown, when the valve core 4 is in the position of opening the drain port 2011, the bottom end surface of the valve core 4 extends outwards by a distance H1 relative to the bottom end surface of the coil 5, H>H1≥0mm; when H1=0mm, that is, after the valve core 4 moves upward to open the drain port 2011, the bottom of the valve core 4 is flush with the bottom end surface of the coil 5. At this time, when the valve core 4 is in the position of closing the drain port 2011, H>0mm, at this time, H is the distance the valve core 4 moves upward, preferably, H≥2mm; when H1>0mm, that is, the valve core After the valve core 4 moves upward to open the drain port 2011, the bottom of the valve core 4 is not flush with the bottom end surface of the coil 5. At this time, when the valve core 4 is in the position of closing the drain port 2011, H>H1, so that after the valve core 4 moves upward to open the drain port 2011, the bottom end surface of the valve core 4 is still located below the bottom end surface of the coil 5, that is, the bottom of the valve core 4 is located outside the coil 5. This part of the valve core 4 does not generate magnetic force, that is, it does not generate resistance that affects the upward movement of the valve core 4. Preferably, H≥5mm>H1≥1mm.

[0039] Another case mentioned above, such as Figure 4 As shown, when the valve core 4 is in the state of opening the drain port 2011, the bottom end face of the valve core 4 retracts inwardly by a distance H2 relative to the bottom end face of the coil 5, and H2>0mm; when H=0mm, that is, when the valve core 4 closes the drain port 2011, the bottom end face of the valve core 4 is flush with the bottom end face of the coil 5, then after the valve core 4 moves upward to open the drain port 2011, the bottom end face of the valve core 4 retracts inwardly by a distance H2 relative to the bottom end face of the coil 5, and at this time the bottom end face of the valve core 4 is located within the coil 5, but as the distance between the top end face of the valve core 4 and the bottom end face of the magnetic core 6 becomes closer during the upward movement of the valve core 4, the magnetic force becomes greater, and the coil 6 can be ignored at this time. 5, the bottom of the valve core 4 produces a downward attraction force on the bottom of the valve core 4, which affects the upward movement of the valve core 4, that is, the influence of the resistance is ignored; when H>0mm, at this time, the valve core 4 can also move upward so that the bottom end face of the valve core 4 retracts inwardly by a distance H2 relative to the bottom end face of the coil 5. It is only necessary to set H2>H, H2 is the distance that the valve core 4 moves upward. After the valve core 4 moves upward, the closer the distance between the top end face of the valve core 4 and the bottom end face of the magnetic core 6 is during the upward movement of the valve core 4, the greater the magnetic force is. At this time, the influence of the downward attraction force on the bottom of the coil 5 on the upward movement of the valve core 4 can be ignored, that is, the influence of the resistance is ignored.

[0040] The above two situations can effectively reduce the downward magnetic force generated by the bottom of the coil 5 on the bottom end face of the valve core 4, so the magnetic force required for the magnetic core 6 to drive the valve core 4 to move upward can be effectively reduced, and the power of the coil 5 can be reduced accordingly. By reducing the number of turns of the coil 5, the magnetic core 6 can drive the valve core 4 to move.

[0041] The magnetic gathering structure of this solution, the digester also includes a magnetic gathering component 7, the magnetic gathering component 7 is located on the outside of the coil 5, the magnetic gathering component 7 covers at least a part of the outer surface of the coil 5, the magnetic gathering component 7 covers the coil 5 so that the magnetic gathering component 7 can play a magnetic gathering role, and the magnetic gathering component 7 can make the magnetic field generated after the coil 5 is energized to gather to the upper part and the inside of the coil 5, which is beneficial to the absorption of the magnetic field of the coil 5 by the magnetic core 6 and the valve core 4, and is beneficial to enhance the magnetic core 6 and the valve core 4 to generate more magnetic force inside the coil 5. The vertical attraction magnetic force of the magnetic core 6 to drive the valve core 4 to move upward is greater, ensuring that the movement of the valve core 4 is more stable and reliable.

[0042] Optionally, the magnetic concentrating component 7 includes a first magnetic concentrating part 701, which at least covers a portion of the top end surface of the coil 5. The first magnetic concentrating part 701 allows the magnetic field generated after the coil 5 is energized to be concentrated on the magnetic core 6. The magnetic field can be effectively concentrated, so that the magnetic force of the magnetic core 6 to drive the valve core 4 to move is enhanced. The first magnetic concentrating part 701 guides the magnetic field generated by the coil 5, guiding the magnetic field to concentrate on the magnetic core 6, which is conducive to the magnetic core 6 generating stronger magnetic force.

[0043] Preferably, the magnetic core 6 is set to a raised structure relative to the first magnetic concentrator 701, and the magnetic core 6 is located on the inner side of the coil 5, that is, the first magnetic concentrator 701 covers the top end face of the coil 5, and the magnetic core 6 extends downward relative to the first magnetic concentrator 701 as a raised structure, which is beneficial for the magnetic field guided by the first magnetic concentrator 701 to be concentrated on the magnetic core 6, and is beneficial for the magnetic force driven by the magnetic core 6 to move the valve core 4 to be concentrated, thereby realizing the corresponding mutual magnetic attraction between the magnetism and the valve core 4.

[0044] Optionally, the magnetic concentrating component 7 also includes a second magnetic concentrating part 702, which at least covers a part of the side surface and / or bottom end face of the coil 5. The second magnetic concentrating part 702 can guide the magnetic field generated after the coil 5 is energized. The second magnetic concentrating part 702 covers the side surface of the coil 5 to achieve less leakage of the magnetic field generated by the coil 5. The second magnetic concentrating part 702 covers the bottom end face of the coil 5 to achieve upward concentration of the magnetic field generated by the coil 5. The magnetic field on the outer surface and bottom end face of the coil 5 can be effectively concentrated upward and inward under the guiding magnetic concentration action of the second magnetic concentrating part 702, so that the magnetic force between the magnetic core 6 and the valve core 4 is enhanced when the coil 5 is energized.

[0045] Preferably, the second magnetic concentrator 702 covers the entire side end face and the bottom end face of the coil 5. The second magnetic concentrator 702 has the best guiding and concentrating effect on the magnetic field generated by the coil 5, which can reduce the leakage of the magnetic field of the coil 5 and make the magnetic field of the coil 5 concentrated toward the upper part and the inside of the coil 5, which is conducive to the concentration of the magnetic field on the magnetic core 6 and the valve core 4.

[0046] Optionally, the magnetic core 6 and the first magnetic concentrator 701 are set as an integrated integral structure, or they can be set as independent split structures, both of which can achieve the magnetic concentrating effect of the first magnetic concentrator 701; preferably, the magnetic core 6 and the first magnetic concentrator 701 are set as an integrated integral structure, and the magnetic concentrator 701 has the best magnetic concentrating effect.

[0047] The magnetic collecting component 7 has the effect of three-dimensionally guiding magnetic collection. The first magnetic collecting component 701 and the second magnetic collecting component 702 together form a three-dimensional covering magnetic collection effect on the coil 5. After the coil 5 is energized, the magnetic field generated by the first magnetic collecting component 701 and the second magnetic collecting component 702 can better guide the magnetic field to be collected on the upper part and inside of the coil 5 under the three-dimensional covering magnetic collection. On the one hand, the magnetic core 6 can collect more magnetic fields, so that the magnetic force of the magnetic core 6 is enhanced. On the other hand, the valve core 4 located on the inner side of the coil 5 can collect more magnetic fields, so that the magnetic force of the valve core 4 is enhanced, and the mutual magnetic force between the magnetic core 6 and the valve core 4 is enhanced and more stable, so that the magnetic core 6 can drive the valve core 4 to move upward through the vertical magnetic force of attraction, and drive the valve core 4 to move upward more stably and reliably.

[0048] Optionally, in order to achieve a better magnetic focusing effect, the magnetic focusing component 7 and the valve core 4 are set to be made of iron or stainless steel, which is beneficial to the magnetic focusing effect of the magnetic focusing component 7. When the coil 5 is energized, the magnetic focusing component 7 can better focus the magnetic field generated by the coil 5, so that the magnetic field can be concentrated on the magnetic core 6. At the same time, the valve core 4 can also generate a stronger magnetic force in the coil 5, so that the magnetic force of the magnetic core 6 to drive the valve core 4 to move through magnetic force is stronger and more stable.

[0049] Among them, when the second magnetic concentrator 702 covers a part of the bottom end face of the coil 5, especially when it covers the entire bottom end face of the coil 5, the coil 5 and the second magnetic concentrator 702 both generate a downward attractive magnetic force on the bottom end face of the valve core 4. The magnetic force is the resistance to prevent the valve core 4 from moving upward. At this time, the resistance is relatively large. Through this solution, the bottom end face of the valve core 4 is set outside the coil 5, which can more effectively reduce the downward attractive magnetic force generated by the coil 5 and the second magnetic concentrator 702 on the bottom end face of the valve core 4, that is, effectively reduce the resistance, eliminate the problem of large resistance caused by the setting of the second magnetic concentrator 702, and achieve the second magnetic concentrator 702. The good guiding magnetic effect will be achieved without generating resistance that affects the upward movement of the valve core 4.

[0050] Optionally, for the inner pot 2 structure of the present solution, a drainage channel 201 is provided on the inner pot 2, the drain port 2011 is located at the end of the drainage channel 201, the coil 5 is located on the outside of the drainage channel 201, the drainage channel 201 serves as an independent drainage part on the inner pot 2, and the valve core 4 is located on the inside of the drainage channel 201, that is, the valve core 4 moves up and down in the drainage channel 201 to realize the opening and closing effect of the drain port 2011, and the magnetic core 6 is installed on the outside of the drainage channel 201 and can be reasonably installed according to actual needs, and it is only necessary to ensure that the magnetic core 6 can drive the valve core 4 to move through magnetic force.

[0051] During initial operation of the steamer of this embodiment, the user may first add some water to the outer pot 1 and simultaneously add some water to the inner pot 2. The heating element is located in the pot body 3 and at the lower outer side of the outer pot 1. The heating element heats the outer pot 1 to generate steam and heats the inner pot 2. Alternatively, during initial operation of the steamer, the user may only add water to the inner pot 2. After the steamer is started, a control module on the electronic control board is provided with a working program. The control module controls the power module 8 to energize the coil 5 for a certain period of time, so that the magnetic core 6 moves the valve core 4 through magnetic force and then opens the drain port 2011. At this time, the inner pot 2 discharges some water into the outer pot 1, so that both the outer pot 1 and the inner pot 2 are filled with water. The heating element then heats the outer pot 1 to generate steam and heats the inner pot 2. In both embodiments, during initial operation of the steamer, the outer pot 1 can contain some water for the heating element to heat the outer pot 1, and then the steam heats the inner pot 2 to cook, thereby preparing low-sugar food, such as low-sugar rice.

[0052] The valve core 4 of this solution is detachable and can be cleaned independently. The main structure is that the valve core 4 is installed on the shaft rod, and the valve core 4 can move on the shaft rod. A filter is installed on the upper end of the shaft rod. The filter plays a certain filtering role, and the filter is placed on the inner bottom end surface of the inner pot 2 to support the valve core 4; that is, the valve core 4, the shaft rod, and the filter can be disassembled as a whole and taken out for independent cleaning. The whole is detachably installed in the drainage channel 201. The detachable installation makes it convenient to clean the valve core 4.

[0053] In this solution, one end of the coil 5 is electrically connected to the power module 8 through the inner pot 2, and / or the other end of the coil 5 is electrically connected to the power module 8 through the outer pot 1. Specifically, the inner pot 2 and the outer pot 1 are mainly used as energized carriers to realize the power supply to the coil 5. One end of the coil 5 is electrically connected to the power module 8 through the inner pot 2, mainly one end of the coil 5 is electrically connected to the inner pot 2, and the inner pot 2 is electrically connected to the power module 8; the other end of the coil 5 is electrically connected to the power module 8 through the outer pot 1, mainly the other end of the coil 5 is electrically connected to the outer pot 1, and the outer pot 1 is electrically connected to the power module 8; the outer pot 1 and the inner pot 2 are respectively electrically connected to the power module 8, that is, One end of the coil 5 can be electrically connected to the power module 8 through the inner pot 2, and the other end of the coil 5 can be electrically connected to the power module 8 through the outer pot 1, thereby realizing power supply to the coil 5 by the power module 8; when the inner pot 2 is placed in the outer pot 1, the other end of the coil 5 is electrically connected to the outer pot 1 mainly by arranging a guide column on the inner pot 2, and the whole process realizes the path for powering the coil 5; the current on the power module 8 enters the inner pot 2, enters one end of the coil 5 through the inner pot 2, then enters the other end of the coil 5, and then enters the outer pot 1, and finally returns to the power module 8 through the wire or temperature sensor, thereby realizing the entire current loop for powering the coil 5.

[0054] The circuit structure of the digester of this scheme is mainly to supply power to the coil 5 and ensure that the coil 5 is electrically connected to the power module 8. Only when the coil 5 is energized can the magnetic core 6 and the valve core 4 generate a certain magnetic force, so that the magnetic core 6 can drive the valve core 4 to move by the magnetic force. The coil 5 is electrically connected to the power module 8. When the coil 5 is energized, the magnetic core 6 can drive the valve core 4 to move by the magnetic force to open the drain outlet 2011; the power module 8 is electrically connected to the circuit board, and the control module on the circuit board realizes the on and off control of the power supply of the power module 8. When the coil 5 needs to be powered, the control module controls the power module 8 to energize the coil 5. At this time, the coil 5 can realize that the magnetic core 6 drives the valve core 4 to move to achieve the effect of opening and closing the drain outlet 2011.

[0055] The coil 5 of the present invention is formed by winding a wire. The function of the coil 5 is that when the coil 5 is energized, the current passing through the coil 5 causes the magnetic core 6 and the valve core 4 located inside the coil 5 to generate a certain magnetic force. When the coil 5 is energized, the magnetic core 6 and the valve core 4 have a magnetic force, which mainly has a magnetic force of mutual attraction. The magnetic core 6 drives the valve core 4 to move upward through the magnetic force to open the drain outlet 2011; when the coil 5 is not energized, the magnetic force between the magnetic core 6 and the valve core 4 disappears. At this time, the valve core 4 moves downward under the action of gravity. The whole process realizes the magnetic force supply of the coil 5 to the magnetic core 6 and the valve core 4; whether the coil 5 is energized or not mainly depends on whether the coil 5 needs to be connected to the power module 8, and the power supply to the coil 5 is realized by the power module 8; the power supply structure of the coil 5 in the present invention solves the problem that the structure of the power supply to the coil 5 of the existing steamer is complex, and the inner pot 2 is difficult to clean and unsafe to use due to the installation of the power plug terminal on the inner pot 2.

[0056] The steamer of this scheme makes low-sugar food, such as the process of making low-sugar rice. Water is contained in the outer pot 1, and the inner pot 2 is used to hold water and rice. The heating element heats the outer pot 1. The water in the outer pot 1 generates high-temperature steam under the heating action of the heating element. The steam can directly perform high-temperature steam heating on the inner pot 2. It is also possible to provide a vent hole on the upper part of the inner pot 2 so that part of the high-temperature steam can enter the inner pot 2 from the outer pot 1, so that the high-temperature steam can steam-heat the water and rice in the inner pot 2. After heating for a period of time, the water and rice are fully boiled in the inner pot 2. At this time, the power module 8 realizes the power supply of the coil 5 through the inner pot 2 and the outer pot 1. A power supply path is formed among block 8, the inner pot 2, the coil 5, and the outer pot 1. When the coil 5 is energized, the magnetic core 6 and the valve core 4 can generate a certain magnetic force. At this time, the magnetic core 6 can drive the valve core 4 to move upward through the magnetic force, so that the drain port 2011 is opened, and the rice soup in the inner pot 2 enters the outer pot 1 through the drain port 2011, thereby realizing the separation of water and rice in the inner pot 2. During the discharge process, the rice soup takes away the starch and sugar in the rice, thereby reducing the content of starch and sugar in the rice in the inner pot 2. After the water and rice in the inner pot 2 are separated, the heating element continues to heat so that the rice in the inner pot 2 is steamed under high-temperature steam, thereby realizing the production of low-sugar rice.

[0057] Low-sugar foods, such as low-sugar rice, can be eaten by diabetics or obese people because of their low starch and sugar content. They can reduce their intake of starch and sugar and increase their sense of fullness. Low-sugar rice tastes better than ordinary rice, and can also help prevent diabetes when eaten by normal people.

[0058] Working principle: The steamer of this scheme includes an inner pot 2 and an outer pot 1. The inner pot 2 is located in the outer pot 1. The food and water are located in the inner pot 2. The outer pot 1 contains water. A magnetic core 6, a valve core 4, and a coil 5 are installed on the inner pot 2. When the coil 5 is energized, the magnetic core 6 and the valve core 4 generate a magnetic force so that the magnetic core 6 drives the valve core 4 to move upward to open the drain port 2011. At this time, the water in the inner pot 2 can be discharged into the outer pot 1 through the drain port 2011, thereby separating the water in the inner pot 2 from the food. When the coil 5 is de-energized, the valve core 4 moves downward under the action of gravity to close the drain port 2011. At this time, the inner pot 2 is The water in the pot 2 cannot pass through the drain outlet 2011. The heating element heats the outer pot 1 to generate steam and heats the inner pot 2, which can realize the preparation of low-sugar ingredients, and is particularly convenient for making low-sugar rice. Regarding the magnetic core 6 driving the valve core 4 to move, in order to reduce the resistance of the coil 5 to the valve core 4, the resistance is the magnetic force generated by the bottom of the coil 5 to the bottom of the valve core 4, and the bottom end face of the valve core 4 is set to be flush with the bottom end face of the coil 5 or to protrude outward, so that the bottom of the valve core 4 is located outside the coil 5, that is, this part does not generate magnetic force, which is conducive to the magnetic core 6 driving the valve core 4 to move upward.
