Description

Technical Field

[0001] The invention belongs to the technical field of household appliances, in particular to an energy-saving electromagnetic cooker. Background Art

[0002] The principle of induction cooker is electromagnetic induction, that is, using alternating current to pass through a coil to generate an alternating magnetic field with a constantly changing direction. Eddy current will appear inside the conductor in the alternating magnetic field, which is caused by the eddy electric field driving the movement of carriers in the conductor; the Joule heating effect of the eddy current causes the conductor to heat up, thereby achieving heating; in the prior art, when using an induction cooker to boil water in an RV or a boat, the kettle will shift on the induction cooker panel due to the shaking of the car body or the boat, resulting in a relative displacement between the bottom of the kettle and the coil inside the induction cooker, which reduces the heated part of the kettle, increases the heating time of the kettle, causes a waste of electricity, and is not conducive to saving resources. At the same time, heating the kettle will cause it to vibrate up and down, which will damage the microcrystalline panel and internal components of the induction cooker, shortening its service life.

[0003] Some technical solutions for household energy-saving induction cookers have also appeared in the prior art. For example, a Chinese patent with application number CN202010366732.8 discloses a household induction cooker, including a base, a main body mechanism, a heat conduction plate, a support mechanism, a support plate, a support column, a sliding column, a slot, a limit mechanism, a toggle plate, a drive plate and a card plate; when in use, the device only tightens the bottom side of the cookware, and cannot effectively prevent the induction cooker from moving. When the induction cooker heats the kettle, the kettle will be affected by the alternating magnetic field and vibrate up and down, and the water in the kettle will flow out to the surface of the microcrystalline panel, and there is a risk of water flowing into the inside of the induction cooker, which can easily cause damage to the electrical components inside the induction cooker. Summary of the invention

[0004] In order to make up for the deficiencies of the prior art and solve the problem that in the prior art, the kettle is in close contact with the panel, and the kettle is easy to slide on the panel when heated, so that relative displacement occurs between the bottom surface of the kettle and the internal coil of the induction cooker, which reduces the heated part of the kettle, increases the heating time of the kettle, causes power waste, and is not conducive to saving resources, and heating the kettle will cause it to vibrate up and down, which will damage the microcrystalline panel and the internal components of the induction cooker and shorten their service life, the present invention proposes an energy-saving induction cooker that is particularly suitable for use in RVs and ships.

[0005] The technical solution adopted by the present invention to solve its technical problems is as follows: the energy-saving induction cooker described in the present invention comprises a base, a panel and a controller; the panel is fixedly connected to the upper surface of the base; the base is provided with a first groove on the upper surface; a disc is fixedly connected to the bottom of the first groove through a bracket; a coil is fixedly connected to the upper surface of the disc; a plurality of first slide grooves are provided on the panel, and the first slide grooves are evenly distributed around the center of the coil; a sleeve is slidably connected in the first slide groove; a ring is slidably connected inside the sleeve; a second slide groove is provided through the surface of the sleeve on one side close to the coil; A connecting rod is slidably connected in the second slide groove; the connecting rod is fixedly connected to the outer surface of the ring; a fixing rod is hinged above the connecting rod; a motor is fixedly connected in the first groove just below the first slide groove; an extension rod is fixedly connected to the rotating shaft of the motor; the extension rod passes through the bottom of the sleeve and the ring design; an upper thread is provided on the circumferential surface of the upper part of the extension rod; a lower thread is provided on the extension rod near the motor; the upper thread and the lower thread do not contact each other; the extension rod is connected to the sleeve through the lower thread; the extension rod is connected to the ring through the upper thread; the motor is controlled by a controller;

[0006] When working, in the initial state, the surface of the ring does not contact the lower surface of the sleeve, and the lower surface of the connecting rod contacts the lower surface of the second slide groove; the extension rod is threadedly connected with the sleeve through the lower thread, and the lower thread is not threadedly connected with the ring; the ring does not contact the upper thread; the fixed rod is completely retracted into the second slide groove, and the upper end of the fixed rod is in a state of tilting toward the coil direction;

[0007] When the user uses the induction cooker to boil water and needs to fasten the kettle to the upper surface of the panel, it is necessary to use a kettle that is suitable for the size of the induction cooker of the present invention to boil water. Multiple motors are connected in parallel through circuits and controlled by a controller. At this time, the kettle is placed on the upper surface of the panel so that the central axis of the kettle coincides with the central axis of the coil. After that, the power switch and the switch of the control motor are turned on. At this time, the motor works and drives the extension rod to rotate clockwise. In the initial state, the lower thread is connected to the sleeve thread, and the sleeve and the first slide groove are both square, and the sleeve cannot rotate. As a result, when the extension rod rotates clockwise, it drives the sleeve to move upward inside the first slide groove. When the sleeve moves upward, the second slide groove is exposed by one-fourth of the upper surface of the panel. At this moment, the upper thread and the ring form a threaded connection. At this time, as the extension rod continues to rotate, the sleeve is driven upward. Because the ring and the upper thread form a threaded connection, at the same time, the ring is fixedly connected to the connecting rod, and the connecting rod is slidably installed in the second slide groove, there is no relative rotation between the ring and the sleeve. Therefore, when the extension rod rotates, the ring moves upward. At this time, the ring drives the connecting rod to move upward. Because the upper end of the fixed rod is inclined toward the coil direction in the initial state, the connecting rod moves upward and drives the fixed rod to gradually extend out of the second slide groove in the direction of the coil. Because the extension rod drives the sleeve and the ring to rise at the same rate, the fixed rod extends out of the second slide groove at a uniform speed, effectively avoiding the fixed rod from being pulled out of the second slide groove. The speed of extending the second slide groove is greater than the rising speed of the sleeve, causing the fixed rod to hit the inner wall of the first slide groove, causing damage to the panel; when the fixed rod is fully extended from the inside of the first slide groove, the controller controls the motor to stop working, at this time the upper surface of the fixed rod contacts the upper surface of the internal space of the sleeve, and the lower surface of the fixed rod contacts the upper surface of the connecting rod, so that the fixed rod is clamped by the connecting rod and the sleeve, and the lower surface of the connecting rod is located above the panel, at this time, multiple fixed rods contact and clamp the outer surface of the circumference of the kettle of the size adapted to the induction cooker of the present invention at the end away from the motor, when the kettle vibrates during the boiling process, multiple fixed rods can prevent the kettle from shifting, avoid the kettle receiving the reduced alternating magnetic field, thereby effectively saving electricity and avoiding resource The invention can also avoid water splashing out of the kettle spout due to excessive vibration amplitude of the kettle, effectively avoid the vibration of the kettle on the panel, and reduce the damage of the panel and internal parts of the induction cooker caused by the vibration of the kettle; in addition, the invention is applicable to containers with the same bottom diameter as the kettle proposed in the invention, and can be fixed, wherein boiling water in the kettle is a typical case in the invention; and after the sleeve is reset, the surface of the panel is flat, saving the surface space above the panel, increasing the beauty of the induction cooker, and at the same time, a larger container can be placed on the panel, effectively avoiding the bottom of the container contacting the upper surface of the sleeve after the sleeve extends out of the first slide slot, resulting in an increase in the distance between the bottom of the container and the coil, thereby increasing the heating time and wasting electricity;When a container with a smaller bottom diameter than the kettle of the present invention is placed on the panel, when the liquid in the container is heated to boiling point, the container vibrates, causing the container to shift, but the container is still within the range of the alternating magnetic field emitted by the coil, and the container can still be fully heated, thereby saving electricity;

[0008] When the water is heated, turn off the power switch, turn on the switch of the control motor, so that the motor reverses, the motor drives the extension rod to rotate counterclockwise, and the extension rod drives the ring to move downward inside the sleeve. At the same time, the extension rod drives the sleeve to move in the direction of the first groove, and the sleeve descends at the same rate as the ring. When the fixed rod descends with the ring, when the lower surface of the fixed rod contacts the upper surface of the panel, the fixed rod is subjected to the reverse force of the first slide groove, so that the upper end of the fixed rod gradually tilts away from the coil. At this time, as the ring continues to move downward, the fixed rod gradually moves into the second slide groove Reset, so that the fixing rod is gradually in a vertical state. When the sleeve moves downward so that the second slide groove exposes one-fourth of the upper surface of the panel, the ring ends the connection with the upper thread. At this time, the friction force generated by the contact between the lower surface of the fixed block and the upper surface of the panel and the upper surface of the fixed block and the lower surface of the sleeve causes the ring to slowly descend until the lower surface of the connecting rod contacts the lower surface of the second slide groove. The ring stops moving and the fixing rod completely enters the second slide groove. When the upper surface of the sleeve is parallel to the upper surface of the panel, the controller turns off the switch for the motor to operate, and the device returns to its initial state.

[0009] Preferably, the fixing rod is hinged with a fixing block at one end away from the motor; and the fixing block has a plurality of rubber blocks evenly arranged on a surface of a side away from the motor.

[0010] During operation, when the fixed block contacts the surface of the kettle circle, it continues to move with the ring, so that the end of the fixed rod close to the kettle continues to press down, which increases the squeezing force of the fixed block on the kettle. Since the fixed block is hinged to the fixed rod, it is ensured that the fixed block can be tightly attached to the surface of the kettle, avoiding excessive force on a single fixed rod, causing damage to internal parts of the device and damage to the surface of the kettle. Multiple rubber blocks can effectively increase the friction between the surface of the fixed block and the surface of the kettle circle, improve the fixing effect of the fixed block on the kettle, and effectively avoid the displacement of the kettle due to vibration during heating. At the same time, the rubber block reduces the wear between the fixed block and the kettle, thereby improving the service life and external aesthetics of the kettle.

[0011] Preferably, the upper part of the fixed block is slidably connected to a moving block on the side close to the coil; the moving block is provided with a second groove on the surface close to the motor; the second groove is fixedly connected to a spring sheet on the surface in the horizontal direction; the other end of the spring sheet is fixedly connected to the surface of the fixed block away from the motor;

[0012] During operation, when the kettle is heated, after the fixed block fixes the kettle, the spring piece fixed to the fixed block absorbs heat. Because the spring piece is made of memory metal with a two-way memory effect, when the spring piece is heated, the spring piece bends toward the first groove, and the spring piece drives the moving block to move toward the first groove. At this time, the kettle is subjected to a force toward the panel from the rubber block on the surface of the moving block, so that the kettle is pressed against the panel during the heating process, thereby effectively avoiding the contact time between the lower surface of the kettle and the upper surface of the panel being reduced due to the vibration of the kettle during the heating process, resulting in a longer time to heat the water, thereby effectively saving electricity and resources.

[0013] Preferably, the upper circumference of the first chute is designed to be inclined toward the outside of the first chute; the first chute is provided with a first water trough on the inclined surface; the upper part of the sleeve is designed to fit with the inclined surface; a sponge is fixedly connected to the upper circumference of the sleeve on the inclined surface; a mounting tube is fixedly connected to the lower surface of the panel on the circumference of the first chute; the cross section of the mounting tube is hook-shaped; a scraper is fixedly connected to the bottom circumference of the sleeve; the surface of the scraper fits the inner wall of the mounting tube and the inner wall of the first chute;

[0014] During operation, because the sponge and the first water tank correspond to each other, and after the sleeve is retracted into the first chute, the sponge is inserted into the first water tank, so that when the sleeve finishes rising, the upper surface of the scraper block just contacts the first chute below the inclined surface. When the water boils, water droplets splash out through the spout and fall onto the panel. When the outflowing water flows into the first chute, it first enters the first water tank opened on the inclined surface of the first chute. After the sleeve is reset, the sponge fixedly connected to the circumference of the inclined surface above the sleeve is arranged corresponding to the first water tank, so that the sponge absorbs water to prevent water from flowing into the induction cooker and damaging the internal components of the induction cooker, thereby improving Service life of induction cooker; when the outflowing water flow exceeds the capacity of the first water tank, the water flow flows into the space above the scraper block. Because the circumferential surface of the scraper block fits the inner wall of the mounting tube and the inner wall of the first slide groove, the water flow will not flow into the space below the scraper block. Before the sleeve is reset, the splashed water is evaporated by the temperature generated inside the induction cooker during operation. After the sleeve is reset, the water flow is still in the space above the scraper block. As the residual heat of the panel is conducted to the sleeve, the water flow in the space above the scraper block can be slowly evaporated. When there is too much water flow, the water flow in the space above the scraper block can also be cleaned manually.

[0015] Preferably, a second water groove is provided on the outer surface of the scraping block; the second water groove is designed to be inclined from high to low relative to the hook-shaped space below the mounting tube from the side away from the coil to the side close to the coil;

[0016] During operation, if water flows through the space above the scraper block to the space below the scraper block, the water will first enter the second water tank and be collected by the second water tank. Since the second water tank is tilted from the side away from the coil to the side close to the coil, relative to the hook-shaped space below the mounting tube, the water flowing into the second water tank flows to the part of the second water tank close to the coil. Since the coil generates heat during operation, the water can be slowly evaporated to prevent the water from entering the internal space of the second groove and damaging the internal components of the induction cooker. Even if the water flows through the second water tank to the space below the scraper block, since the cross-section of the mounting tube is hook-shaped, the hook-shaped space below the mounting tube collects the water again to prevent water droplets from directly entering the interior of the induction cooker, thereby effectively improving the practicability of the device.

[0017] Preferably, a first magnet is fixedly connected inside the first water trough at a side close to the second chute; a second magnet is fixedly connected inside the fixing rod;

[0018] During operation, when the fixing rod is reset to the inner space of the second slide slot, the first magnet and the second magnet repel each other, and the repulsive force of the first magnet on the second magnet is greater than the gravity of the second magnet, the gravity of the fixing rod, the gravity of the fixing block, the gravity of the moving block, the gravity of the spring sheet, the gravity of the rubber block and the friction between the fixing block and the connecting block, so that when the fixing block is retracted into the second slide slot, the lower surface of the fixing block is prevented from directly contacting the panel at the first slide slot, reducing the wear of the panel at the opening of the first slide slot and the wear of the fixing rod, thereby improving the service life of the panel and the fixing rod, but when the upper end of the fixing rod moves toward the outside of the second slide slot, because the mounting cylinder is made of iron material, there is an attractive force between the second magnet and the mounting cylinder, and because there is a repulsive force between the second magnet and the first magnet, the upper end of the fixing rod is inclined toward the coil direction when it extends out of the second slide slot, effectively improving the linkage and practicality of the device.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The energy-saving induction cooker described in the present invention can realize that a plurality of fixing rods can contact and clamp the outer surface of the circumference of a kettle of a size adapted to the induction cooker of the present invention at the end away from the motor by arranging an extension rod, a sleeve, a ring, a fixing rod, a connecting rod, a motor and an extension rod. When the kettle vibrates during the boiling process, the plurality of fixing rods can prevent the kettle from shifting and prevent the kettle from receiving a reduced alternating magnetic field, thereby effectively saving electricity and avoiding waste of resources. At the same time, it can prevent the kettle from vibrating and reduce the possibility of water in the kettle flowing out through the spout.

[0021] 2. The energy-saving induction cooker described in the present invention can realize that after the spring block absorbs heat, the kettle is subjected to a force toward the panel from the rubber block on the surface of the moving block, thereby effectively avoiding the contact time between the lower surface of the kettle and the upper surface of the panel being reduced due to the vibration of the kettle during heating, resulting in a longer time for heating the water, thereby effectively saving electricity and conserving resources.

[0022] 3. The energy-saving induction cooker described in the present invention can realize that the second water tank is designed to decrease in height from the side far away from the coil to the side close to the coil by setting a scraper block and a second water tank, so that the water flowing into the second water tank flows to the part of the second water tank close to the coil. Since the coil generates heat during operation, the water can be slowly evaporated to prevent the water from entering the internal space of the first groove and damaging the internal components of the induction cooker.

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0029] like Figures 1 to 3As shown, an energy-saving induction cooker described in the present invention comprises a base 1, a panel 2 and a controller; the panel 2 is fixedly connected to the upper surface of the base 1; the base 1 is provided with a first groove 3 on the upper surface; a disc 5 is fixedly connected to the bottom of the first groove 3 through a bracket 4; a coil 6 is fixedly connected to the upper surface of the disc 5; a plurality of first slide grooves 7 are provided on the panel 2, and the first slide grooves 7 are evenly distributed around the center of the coil 6; a sleeve 8 is slidably connected in the first slide groove 7; a ring 9 is slidably connected inside the sleeve 8; a second slide groove 11 is penetrated through the surface of the sleeve 8 on one side close to the coil 6; a connecting rod 12 is slidably connected in the second slide groove 11; the connecting rod 1 2 is fixedly connected to the outer surface of the ring 9; a fixing rod 13 is hinged above the connecting rod 12; a motor 14 is fixedly connected in the first groove 3 just below the first slide groove 7; a protruding rod 15 is fixedly connected to the rotating shaft of the motor 14; the protruding rod 15 passes through the bottom of the sleeve 8 and the ring 9; an upper thread 151 is provided on the upper circumferential surface of the protruding rod 15; the protruding rod 15 is provided with a lower thread 152 in the direction close to the motor 14; the upper thread 151 and the lower thread 152 do not contact each other; the protruding rod 15 is connected to the sleeve 8 through the lower thread 152; the protruding rod 15 is connected to the ring 9 through the upper thread 151; the motor 14 is controlled by a controller.

[0030] During operation, in the initial state, the surface of the ring 9 does not contact the lower surface of the sleeve 8, and the lower surface of the connecting rod 12 contacts the lower surface of the second slide groove 11; the extension rod 15 is threadedly connected with the sleeve through the lower thread 152, and the lower thread 152 is not threadedly connected with the ring 9; the ring 9 does not contact the upper thread 151; the fixing rod 13 is completely retracted into the second slide groove 11, and the upper end of the fixing rod 13 is in a state of tilting toward the coil 6;

[0031] When the user uses the induction cooker to boil water and needs to fasten the kettle to the upper surface of the panel 2, it is necessary to use a kettle that is suitable for the size of the induction cooker of the present invention to boil water. Multiple motors 14 are connected in parallel through lines and controlled by a controller. At this time, the kettle is placed on the upper surface of the panel 2 so that the central axis of the kettle coincides with the central axis of the coil 6. After that, the power switch and the switch of the control motor 14 are turned on. At this time, the motor 14 works and drives the extension rod 15 to rotate clockwise. In the initial state, the lower thread 152 is threadedly connected to the sleeve 8, and the sleeve 8 and the first slide groove 7 are both square, and the sleeve 8 cannot rotate, so that when the extension rod 15 rotates clockwise, it drives the sleeve 8 to move upward inside the first slide groove 7. When the sleeve 8 moves upward so that the second slide groove 11 exposes one quarter of the upper surface of the panel 2, the upper thread 151 forms a threaded connection with the ring 9. At this time, as the extension rod 15 continues to rotate to drive the sleeve 8 upward, the ring 9 forms a threaded connection with the upper thread 151. At the same time, the ring 9 is fixedly connected to the connecting rod 12, and the connecting rod 12 is slidably installed in the second slide groove 11. Therefore, there is no relative rotation between the ring 9 and the sleeve 8. Therefore, when the extension rod 15 rotates, the ring 9 moves upward. At this time, the ring 9 drives the connecting rod 12 to move upward. Because the upper end of the fixed rod 13 is inclined toward the direction of the coil 6 in the initial state, the connecting rod 12 moves upward while driving the fixed rod 1 3 gradually extends out of the second chute 11 in the direction of the coil 6, and because the extension rod 15 drives the sleeve 8 and the ring 9 to rise at the same rate, the fixed rod 13 is uniformly extended out of the second chute 11, effectively avoiding that the fixed rod 13 hits the inner wall of the first chute 7 due to the fixed rod 13 extending out of the second chute 11 at a speed greater than the sleeve 8 rising speed, causing damage to the panel 2; when the fixed rod 13 is fully extended out of the first chute 7, the controller controls the motor 14 to stop working, at this time, the upper surface of the fixed rod 13 contacts the upper surface of the internal space of the sleeve 8, and the lower surface of the fixed rod 13 contacts the upper surface of the connecting rod 12, so that the fixed rod 13 is clamped by the connecting rod 12 and the sleeve 8, and the lower surface of the connecting rod 12 is located at the surface The plurality of fixing rods 13 are arranged above the panel 2, and at this time, the plurality of fixing rods 13 contact and clamp the outer surface of the circumference of the kettle of the size adapted to the induction cooker of the present invention at the end away from the motor 14. When the kettle vibrates during boiling water, the plurality of fixing rods 13 can prevent the kettle from shifting, and prevent the kettle from receiving a reduced alternating magnetic field, thereby effectively saving electricity and avoiding waste of resources; at the same time, it is prevented that the water flows through the spout to the outside due to excessive vibration amplitude of the kettle, and effectively prevents the kettle from vibrating on the panel 2, and reduces the damage of the panel 2 and the internal parts of the induction cooker to the vibration of the kettle; in addition, the present invention is applicable to containers with the same bottom diameter as the kettle proposed in the present invention, and can be fixed, wherein boiling water in the kettle is a typical case in the present invention;After the sleeve 8 is reset, the surface of the panel 2 is flat, which saves the surface space above the panel 2 and increases the aesthetics of the induction cooker. At the same time, a larger container can be placed on the panel 2, effectively preventing the sleeve 8 from extending out of the first slide groove 7, causing the bottom of the container to contact the upper surface of the sleeve 8, resulting in an increase in the distance between the bottom of the container and the coil 6, thereby increasing the heating time and wasting electricity. When a container with a smaller bottom diameter than the kettle proposed by the present invention is placed on the panel 2, when the liquid in the container is heated to the boiling point, the container vibrates, causing the container to shift, but the container is still within the range of the alternating magnetic field emitted by the coil 6, and the container can still be fully heated, thereby saving electricity.

[0032] When the water is heated, turn off the power switch, turn on the switch of the control motor 14, so that the motor 14 reverses, and the motor 14 drives the extension rod 15 to rotate counterclockwise, and the extension rod 15 drives the ring 9 to move downward inside the sleeve 8. At the same time, the extension rod 15 drives the sleeve 8 to move in the direction of the first groove 3, and the sleeve 8 descends at the same rate as the ring 9. In the process of the fixed rod 13 descending with the ring 9, when the lower surface of the fixed rod 13 contacts the upper surface of the panel 2, the fixed rod 13 is subjected to the reverse force of the first slide groove 7, so that the upper end of the fixed rod 13 gradually tilts away from the coil 6. At this time, as the ring 9 continues to move downward, the fixed rod 13 gradually moves toward the second slide groove 11 Internal resetting causes the fixing rod 13 to gradually be in a vertical state. When the sleeve 8 moves downward so that the second slide groove 11 exposes one-fourth of the upper surface of the panel 2, the ring 9 ends the connection with the upper thread 151. At this time, the friction force generated by the contact between the lower surface of the fixing block 16 and the upper surface of the panel 2 and the upper surface of the fixing block 16 and the lower surface of the sleeve 8 causes the ring 9 to slowly descend until the lower surface of the connecting rod 12 contacts the lower surface of the second slide groove 11. The ring 9 stops moving and the fixing rod 13 completely enters the second slide groove 11. When the upper surface of the sleeve 8 is parallel to the upper surface of the panel 2, the controller turns off the switch of the motor 14, and the device returns to its initial state.

[0033] As an embodiment of the present invention, the fixing rod 13 is hinged with a fixing block 16 at one end away from the motor 14 ; the fixing block 16 has a plurality of rubber blocks 17 evenly arranged on the surface of the side away from the motor 14 .

[0034] During operation, when the fixing block 16 contacts the surface of the kettle circumference, it continues to move with the ring 9, so that the fixing rod 13 continues to press down at the end close to the kettle, which increases the squeezing force of the fixing block 16 on the kettle. Since the fixing block 16 is hinged to the fixing rod 13, it is ensured that the fixing block 16 can be tightly attached to the surface of the kettle, avoiding excessive force on the single fixing rod 13, causing damage to the internal parts of the device and damage to the surface of the kettle; multiple rubber blocks 17 can effectively increase the friction between the surface of the fixing block 16 and the surface of the kettle circumference, improve the fixing effect of the fixing block 16 on the kettle, and effectively avoid the displacement of the kettle due to vibration during the heating process. At the same time, the rubber block 17 reduces the wear between the fixing block 16 and the kettle, thereby improving the service life and external aesthetics of the kettle.

[0035] As an embodiment of the present invention, the upper part of the fixed block 16 is slidably connected to a movable block 18 on the side close to the coil 6; the movable block 18 is provided with a second groove 19 on the surface close to the motor 14; the second groove 19 is fixedly connected to a spring sheet 21 on the upper surface in the horizontal direction; the other end of the spring sheet 21 is fixedly connected to the surface of the fixed block 16 on the side away from the motor 14.

[0036] During operation, when the kettle is heated, after the fixed block 16 fixes the kettle, the spring piece 21 fixedly connected to the fixed block 16 absorbs heat. Because the spring piece 21 is made of memory metal with a two-way memory effect, when the spring piece 21 is heated, the spring piece 21 bends toward the first groove 3, and the spring piece 21 drives the moving block 18 to move toward the first groove 3. At this time, the kettle is subjected to a force toward the panel 2 from the rubber block 17 on the surface of the moving block 18, so that the kettle is pressed against the panel 2 during the heating process, thereby effectively avoiding the vibration of the kettle during the heating process, which causes the contact time between the lower surface of the kettle and the upper surface of the panel 2 to be reduced, resulting in a longer time to heat the water, thereby effectively saving electricity and resources.

[0037] As an embodiment of the present invention, the upper circumference of the first slide groove 7 is designed to be inclined toward the outside of the first slide groove 7; the first slide groove 7 is provided with a first water trough 22 on the inclined surface; the upper part of the sleeve 8 is designed to fit the inclined surface; a sponge 23 is fixedly connected to the inclined surface on the upper circumference of the sleeve 8; a mounting tube 24 is fixedly connected to the lower surface of the panel 2 around the first slide groove 7; the cross-section of the mounting tube 24 is hook-shaped; a scraper block 25 is fixedly connected to the bottom circumference of the sleeve 8; the circumferential surface of the scraper block 25 fits the inner wall of the mounting tube 24 and the inner wall of the first slide groove 7.

[0038] During operation, since the sponge 23 and the first water trough 22 correspond to each other, and after the sleeve 8 is retracted into the first chute 7, the sponge 23 is inserted into the first water trough 22, so that when the sleeve 8 finishes rising, the upper surface of the scraper block 25 is just in contact with the first chute 7 below the inclined surface. When the water boils, water droplets splash out through the spout and fall onto the panel 2. When the outflowing water flows into the first chute 7, it first enters the first water trough 22 opened on the inclined surface of the first chute 7. After the sleeve 8 is reset, the sponge 23 fixedly connected to the circumference of the inclined surface above the sleeve 8 is arranged corresponding to the first water trough 22, so that the sponge 23 absorbs water to prevent water from flowing into the interior of the induction cooker and damaging the internal components of the induction cooker. , improving the service life of the induction cooker; when the outflowing water flow exceeds the capacity of the first water tank 22, the water flow flows into the space above the scraper block 25. Because the circumferential surface of the scraper block 25 fits the inner wall of the mounting tube 24 and the inner wall of the first chute 7, the water flow will not flow into the space below the scraper block 25. Before the sleeve 8 is reset, the splashed water is evaporated by the temperature generated inside the induction cooker during operation. After the sleeve 8 is reset, the water flow is still located in the space above the scraper block 25. As the residual heat temperature of the panel 2 is conducted to the sleeve 8, the water flow in the space above the scraper block 25 can be slowly evaporated. When there is too much water flow, the water flow in the space above the scraper block 25 can also be manually cleaned.

[0039] As an embodiment of the present invention, a second water groove 26 is provided on the outer surface of the scraping block 25; the second water groove 26 is tilted from high to low relative to the hook-shaped space below the mounting tube 24 from the side away from the coil 6 to the side close to the coil 6.

[0040] During operation, if water flows through the space above the scraper block 25 to the space below the scraper block 25, the water will first enter the second water tank 26 and be collected by the second water tank 26. Since the second water tank 26 is tilted from the side away from the coil 6 to the side close to the coil 6 relative to the hook-shaped space below the mounting tube 24, the water flowing into the second water tank 26 flows to the part of the second water tank 26 close to the coil 6. Since the coil 6 generates heat during operation, the water can be slowly evaporated to prevent the water from entering the internal space of the second groove 19 and damaging the internal components of the induction cooker. Even if the water flows through the second water tank 26 to the space below the scraper block 25, since the cross-section of the mounting tube 24 is hook-shaped, the hook-shaped space below the mounting tube 24 collects the water again to prevent water droplets from directly entering the interior of the induction cooker, thereby effectively improving the practicability of the device.

[0041] As an embodiment of the present invention, a first magnet 27 is fixedly connected inside the first water tank 22 at a side close to the second chute 11 ; and a second magnet 28 is fixedly connected inside the fixing rod 13 .

[0042] During operation, when the fixing rod 13 is reset to the inner space of the second slide groove 11, the first magnet 27 and the second magnet 28 repel each other, and the repulsive force of the first magnet 27 on the second magnet 28 is greater than the gravity of the second magnet 28, the gravity of the fixing rod 13, the gravity of the fixing block 16, the gravity of the moving block 18, the gravity of the spring 21, the gravity of the rubber block 17, and the friction between the fixing block 16 and the connecting block, so that when the fixing block 16 is retracted into the second slide groove 11, the lower surface of the fixing block 16 is prevented from being directly contacted with the panel 2 at the first slide groove 7. The contact reduces the wear of the panel 2 at the opening of the first slide groove 7 and the wear of the fixing rod 13, thereby increasing the service life of the panel 2 and the fixing rod 13. However, when the upper end of the fixing rod 13 moves toward the outside of the second slide groove 11, because the mounting tube 24 is made of iron material, there is an attractive force between the second magnet 28 and the mounting tube 24, and because there is a repulsive force between the second magnet 28 and the first magnet 27, the upper end of the fixing rod 13 is inclined toward the coil 6 when extending out of the second slide groove 11, which effectively improves the linkage and practicality of the device.

[0043] The specific implementation process is as follows:

[0044] In the initial state, the surface of the ring 9 does not contact the lower surface of the sleeve 8, and the lower surface of the connecting rod 12 contacts the lower surface of the second slide groove 11; the extension rod 15 is threadedly connected with the sleeve through the lower thread 152, and the lower thread 152 is not threadedly connected with the ring 9; the ring 9 does not contact the upper thread 151; the fixing rod 13 is completely retracted into the second slide groove 11, and the upper end of the fixing rod 13 is in a state of being inclined toward the coil 6;

[0045] When the user uses the induction cooker to boil water and needs to fasten the kettle to the upper surface of the panel 2, it is necessary to use a kettle that is suitable for the size of the induction cooker of the present invention to boil water. Multiple motors 14 are connected in parallel through lines and controlled by a controller. At this time, the kettle is placed on the upper surface of the panel 2 so that the central axis of the kettle coincides with the central axis of the coil 6. After that, the power switch and the switch of the control motor 14 are turned on. At this time, the motor 14 works and drives the extension rod 15 to rotate clockwise. In the initial state, the lower thread 152 is threadedly connected to the sleeve 8, and the sleeve 8 and the first slide groove 7 are both square, and the sleeve 8 cannot rotate, so that when the extension rod 15 rotates clockwise, it drives the sleeve 8 to move upward inside the first slide groove 7. When the sleeve 8 moves upward so that the second slide groove 11 exposes one quarter of the upper surface of the panel 2, the upper thread 151 forms a threaded connection with the ring 9. At this time, as the extension rod 15 continues to rotate to drive the sleeve 8 upward, the ring 9 forms a threaded connection with the upper thread 151. At the same time, the ring 9 is fixedly connected to the connecting rod 12, and the connecting rod 12 is slidably installed in the second slide groove 11. Therefore, there is no relative rotation between the ring 9 and the sleeve 8. Therefore, when the extension rod 15 rotates, the ring 9 moves upward. At this time, the ring 9 drives the connecting rod 12 to move upward. Because the upper end of the fixed rod 13 is inclined toward the direction of the coil 6 in the initial state, the connecting rod 12 moves upward while driving the fixed rod 1 3 gradually extends out of the second chute 11 in the direction of the coil 6, and because the extension rod 15 drives the sleeve 8 and the ring 9 to rise at the same rate, the fixed rod 13 is uniformly extended out of the second chute 11, effectively avoiding that the fixed rod 13 hits the inner wall of the first chute 7 due to the fixed rod 13 extending out of the second chute 11 at a speed greater than the sleeve 8 rising speed, causing damage to the panel 2; when the fixed rod 13 is fully extended out of the first chute 7, the controller controls the motor 14 to stop working, at this time, the upper surface of the fixed rod 13 contacts the upper surface of the internal space of the sleeve 8, and the lower surface of the fixed rod 13 contacts the upper surface of the connecting rod 12, so that the fixed rod 13 is clamped by the connecting rod 12 and the sleeve 8, and the lower surface of the connecting rod 12 is located at the surface The plurality of fixing rods 13 are arranged above the panel 2, and at this time, the plurality of fixing rods 13 contact and clamp the outer surface of the circumference of the kettle of the size adapted to the induction cooker of the present invention at the end away from the motor 14. When the kettle vibrates during boiling water, the plurality of fixing rods 13 can prevent the kettle from shifting, and prevent the kettle from receiving a reduced alternating magnetic field, thereby effectively saving electricity and avoiding waste of resources; at the same time, it is prevented that the water flows through the spout to the outside due to excessive vibration amplitude of the kettle, and effectively prevents the kettle from vibrating on the panel 2, and reduces the damage of the panel 2 and the internal parts of the induction cooker to the vibration of the kettle; in addition, the present invention is applicable to containers with the same bottom diameter as the kettle proposed in the present invention, and can be fixed, wherein boiling water in the kettle is a typical case in the present invention;After the sleeve 8 is reset, the surface of the panel 2 is flat, which saves the surface space above the panel 2 and increases the aesthetics of the induction cooker. At the same time, a larger container can be placed on the panel 2, effectively preventing the sleeve 8 from extending out of the first slide groove 7, causing the bottom of the container to contact the upper surface of the sleeve 8, resulting in an increase in the distance between the bottom of the container and the coil 6, thereby increasing the heating time and wasting electricity. When a container with a smaller bottom diameter than the kettle proposed by the present invention is placed on the panel 2, when the liquid in the container is heated to the boiling point, the container vibrates, causing the container to shift, but the container is still within the range of the alternating magnetic field emitted by the coil 6, and the container can still be fully heated, thereby saving electricity.

[0046] When the fixing block 16 contacts the surface of the kettle circumference, it continues to move with the ring 9, so that the fixing rod 13 continues to press down at the end close to the kettle, which increases the squeezing force of the fixing block 16 on the kettle. Since the fixing block 16 is hinged with the fixing rod 13, it is ensured that the fixing block 16 can be closely attached to the surface of the kettle, and it is avoided that the single fixing rod 13 is subjected to excessive force, causing damage to the internal parts of the device and the surface of the kettle; the multiple rubber blocks 17 can effectively increase the friction between the surface of the fixing block 16 and the surface of the kettle circumference, improve the fixing effect of the fixing block 16 on the kettle, and effectively avoid the displacement of the kettle due to vibration during the heating process. At the same time, the rubber block 17 reduces the wear between the fixing block 16 and the kettle, and improves the service life and external aesthetics of the kettle.

[0047] When the kettle is heated, after the fixed block 16 fixes the kettle, the spring piece 21 fixed to the fixed block 16 absorbs heat. Since the spring piece 21 is made of a memory metal with a two-way memory effect, when the spring piece 21 is heated, the spring piece 21 bends toward the first groove 3, and the spring piece 21 drives the moving block 18 to move toward the first groove 3. At this time, the kettle is subjected to a force in the direction of the panel 2 from the rubber block 17 on the surface of the moving block 18, so that the kettle is pressed against the panel 2 during the heating process, thereby effectively avoiding the contact time between the lower surface of the kettle and the upper surface of the panel 2 being reduced due to the vibration of the kettle during the heating process, resulting in a longer time required to heat the water, thereby effectively saving electricity and resources.

[0048] After the water is heated, the power switch is turned off, and the switch of the control motor 14 is turned on, so that the motor 14 is reversed, and the motor 14 drives the extension rod 15 to rotate counterclockwise, and the extension rod 15 drives the ring 9 to move downward inside the sleeve 8. At the same time, the extension rod 15 drives the sleeve 8 to move in the direction of the first groove 3, and the sleeve 8 descends at the same rate as the ring 9. In the process of the fixed rod 13 descending with the ring 9, when the lower surface of the fixed rod 13 contacts the upper surface of the panel 2, the fixed rod 13 is subjected to the reverse force of the first slide groove 7, so that the upper end of the fixed rod 13 gradually tilts away from the coil 6. As the ring 9 continues to move downward, the fixed rod 13 gradually returns to the inside of the second slide groove 11, so that the fixed rod 13 is gradually in a vertical state. In this process, the first magnet 27 and the second magnet 28 repel each other, and the repulsive force of the first magnet 27 on the second magnet 28 is greater than the gravity of the second magnet 28, the gravity of the fixed rod 13, the gravity of the fixed block 16, the gravity of the moving block 18, the gravity of the spring 21, the gravity of the rubber block 17, and the friction between the fixed block 16 and the connecting block, so that when the fixed block 16 shrinks into the second slide groove 11, the lower surface of the fixed block 16 is prevented from being in contact with the connecting block. The panel 2 is in direct contact with the first slide groove 7, which reduces the wear of the panel 2 at the opening of the first slide groove 7 and the wear of the fixing rod 13, thereby increasing the service life of the panel 2 and the fixing rod 13. However, when the upper end of the fixing rod 13 moves toward the outside of the second slide groove 11, because the mounting tube 24 is made of iron material, there is an attractive force between the second magnet 28 and the mounting tube 24, and because there is a repulsive force between the second magnet 28 and the first magnet 27, the upper end of the fixing rod 13 is inclined toward the coil 6 when extending out of the second slide groove 11, which effectively improves the linkage and practicality of the device. When the sleeve 8 When the second slide groove 11 is moved downward so that one quarter of the upper surface of the panel 2 is exposed, the ring 9 ends the connection with the upper thread 151. At this time, the friction force generated by the contact between the lower surface of the fixing block 16 and the upper surface of the panel 2 and the upper surface of the fixing block 16 and the lower surface of the sleeve 8 causes the ring 9 to slowly descend until the lower surface of the connecting rod 12 contacts the lower surface of the second slide groove 11, the ring 9 stops moving, and the fixing rod 13 completely enters the second slide groove 11. When the upper surface of the sleeve 8 is parallel to the upper surface of the panel 2, the controller turns off the switch of the motor 14, and the device returns to the initial state.

[0049] When the device is working, water drops splash through the spout and enter the first chute 7. Because the sponge 23 and the first water tank 22 correspond to each other, and after the sleeve 8 is retracted into the first chute 7, the sponge 23 is inserted into the first water tank 22, so that when the sleeve 8 finishes rising, the upper surface of the scraper block 25 just contacts the first chute 7 below the inclined surface. When the water boils, water drops splash out through the spout and fall onto the panel 2. When the outflowing water flows into the first chute 7, it first enters the first water tank 22 opened on the inclined surface of the first chute 7. After the sleeve 8 is reset, The sponge 23 fixedly connected to the circumference of the inclined surface above the sleeve 8 is arranged corresponding to the first water tank 22, so that the sponge 23 absorbs water to prevent water from flowing into the induction cooker and damaging the internal components of the induction cooker, thereby increasing the service life of the induction cooker; when the outflowing water exceeds the capacity of the first water tank 22, the water flows into the space above the scraper block 25. Because the surface of the scraper block 25 is in contact with the inner wall of the installation cylinder 24 and the inner wall of the first chute 7, the water will not flow into the space below the scraper block 25. Before the sleeve 8 is reset, the splashed water is evaporated by the temperature generated inside the induction cooker during operation. After the sleeve 8 is reset, the water flow is still in the space above the scraper block 25. As the residual heat of the panel 2 is conducted to the sleeve 8, the water flow in the space above the scraper block 25 can be slowly evaporated. When there is too much water flow, the water flow in the space above the scraper block 25 can also be manually cleaned. If water flows from the space above the scraper block 25 to the space below the scraper block 25, the water flow will first enter the second water tank 26 and be collected by the second water tank 26. Because the second water tank 26 moves from the side away from the coil 6 to the side close to the coil 6 relative to the hook below the mounting tube 24, The space is designed to be inclined from high to low, so that the water flowing into the second water tank 26 flows to the part of the second water tank 26 close to the coil 6. Since the coil 6 generates heat during operation, the water can be slowly evaporated to prevent the water from entering the internal space of the second groove 19 and damaging the internal components of the induction cooker. Even if the water flows through the second water tank 26 to the space below the scraper block 25, because the cross-section of the mounting tube 24 is hook-shaped, the hook-shaped space below the mounting tube 24 collects the water again to prevent water droplets from directly entering the interior of the induction cooker, thereby effectively improving the practicability of the device.
