Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to an electromagnetic cooker. Background Art

[0002] Existing electromagnetic cookers have the advantages of being easy to use and highly efficient, and are very popular among users. Electromagnetic cookers mainly rely on electromagnetic waves to act on the heated object on the cooktop to cook. In order to ensure the safety of electromagnetic cookers, temperature sensors are usually installed in electromagnetic cookers for temperature measurement. Currently, the temperature sensors used in electromagnetic cookers are mainly thermistor sensors or infrared temperature sensors. These sensors are mainly installed under the panel when used, so that they can indirectly detect the temperature of the pot on the cooktop. For example, a temperature measuring device disclosed in the prior art CN106439947A includes a mounting plate attached to the heating area of ​​the electromagnetic cooker panel, and at least one mounting hole is opened on the mounting plate, and a wireless passive temperature sensor assembly is correspondingly installed in each mounting hole. The wireless passive temperature sensor assembly is arranged in the temperature measuring device, which can directly measure the temperature of the bottom of the pot, and the temperature measurement accuracy is high. When the wireless passive temperature sensor assembly fails, the wireless passive temperature sensor assembly can be directly repaired, or the mounting plate and the passive temperature sensor assembly can be directly replaced, which reduces the maintenance of the electromagnetic cooker. In addition, it is not necessary to punch holes on the panel of the electromagnetic cooker during installation, so as to avoid the situation that the overflow flows into the electromagnetic cooker during use and damages the electronic components, and can increase the strength of the electromagnetic cooker panel. However, when this electromagnetic cooker is used for high-temperature stir-frying, since the bottom of the pot is in direct contact with the panel, the high temperature generated by the stir-frying will be transmitted to the bottom of the panel along the panel, causing damage to the components below. Utility Model Content

[0003] The utility model provides an electromagnetic cooker to overcome the defect of the electromagnetic cooker in the prior art that the internal components are scalded by the high temperature of the cooker, which can prevent the internal components of the upper panel from being scalded by the high temperature of the cooker and ensure accurate temperature detection of the cooker.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an electromagnetic cooker, including a cooker body, the cooker body including an upper panel and an electromagnetic coil for heating the cooker, the electromagnetic coil is arranged below the upper panel, the electromagnetic cooker also includes a heat-insulating bracket, the upper panel corresponds to the electromagnetic coil to form a heating zone, the heat-insulating bracket can be placed in the heating zone and is used to carry the cooker, the heat-insulating bracket is installed with a wireless temperature detection component, the wireless temperature detection component includes an energy receiving coil, a temperature detection sensor and a wireless communication module electrically connected to each other, the detection end of the temperature detection sensor is close to the cooker, and the horizontal projection of the energy receiving coil is located within the horizontal projection range of the electromagnetic coil, so that the electromagnetic coil can charge the energy receiving coil.

[0005] After adopting the above technical scheme, the utility model has the following advantages: by providing a heat insulating bracket between the upper panel and the pot, the bottom of the pot is separated from the upper panel, so as to avoid the temperature of the pot being transferred to the upper panel and causing high temperature damage to the components below the upper panel when using the electromagnetic cooker for high-temperature stir-frying; and the wireless temperature detection component arranged on the heat insulating bracket can detect the temperature of the pot on the heat insulating bracket, and transmit the temperature data to the control panel through the wireless communication module, so that the user can adjust it according to the temperature data, and because the wireless temperature detection component is located on the heat insulating bracket, it is closer to the pot, and the pot temperature closer to the actual data can be obtained; wherein, the energy receiving coil in the wireless temperature detection component, because its horizontal projection is within the horizontal projection range of the electromagnetic coil, can completely place the energy receiving coil within the alternating magnetic field range of the electromagnetic coil, which helps to improve the efficiency and reliability of wireless power transmission.

[0006] Furthermore, the distance between the electromagnetic coil and the energy receiving coil is less than 15 mm.

[0007] By adopting the above-mentioned technical solution, the distance between the electromagnetic coil and the energy receiving coil is set to be less than 15mm, which can provide stable and sufficient energy for the energy receiving coil. If the distance between the electromagnetic coil and the energy receiving coil is greater than 15mm, the electromagnetic field strength generated by the electromagnetic coil will be weakened due to the large distance between the electromagnetic coil and the energy receiving coil, resulting in the inability to effectively transmit energy to the energy receiving coil.

[0008] Furthermore, the thermal insulation bracket includes a center piece and a plurality of spokes radiating outward from the center piece.

[0009] By adopting the above-mentioned technical solution, a plurality of spokes radiating outward from the center piece can provide stable support for the cookware, preventing the cookware from sliding or tilting when placed on the heat-insulating bracket.

[0010] Furthermore, there are multiple wireless temperature detection components, and wireless temperature detection components are installed on at least two spokes; or, the temperature detection sensor is installed on the center piece, and the energy receiving coil is installed on the spoke.

[0011] By adopting the above-mentioned technical scheme, the temperature of the entire bottom of the cookware is evenly detected by installing a wireless temperature detection component on at least two spokes, so as to obtain the temperature of the entire bottom of the cookware, so that the user can adjust the temperature according to the needs; or, the temperature detection sensor is installed on the center piece. Since the center of the bottom of the cookware is heated higher than the other positions during heating, by measuring the temperature of the center of the bottom of the cookware, temperature data closer to the real data can be obtained, so that the user can control the heating temperature more accurately. At the same time, the energy receiving coil is installed on the spoke, which can reduce the influence of the high temperature at the center of the bottom of the cookware on the energy receiving coil.

[0012] Furthermore, a first magnetic component is installed on the upper panel, and a second magnetic component capable of magnetic attraction with the first magnetic component is provided on the thermal insulation bracket.

[0013] By adopting the above-mentioned technical solution, the first magnetic part cooperates with the second magnetic part on the insulation bracket, which can facilitate the user to place the insulation bracket in a designated position for heating, eliminating the trouble of manual alignment by the user, and realizing automatic calibration by relying on the mutual attraction of magnetic force.

[0014] Furthermore, the horizontal projection of the first magnetic member is outside the horizontal projection range of the electromagnetic coil.

[0015] By adopting the above technical solution, the horizontal projection of the first magnetic part is set outside the horizontal projection range of the electromagnetic coil, away from the magnetic lines of force generated by the electromagnetic coil, thereby avoiding interference of the electromagnetic coil on the first magnetic part, thereby causing the first magnetic part to lose its magnetism.

[0016] Furthermore, the distance between the first magnetic component and the electromagnetic coil is greater than 20 mm.

[0017] By adopting the above-mentioned technical solution, the distance between the first magnetic part and the electromagnetic coil is greater than 20 mm, which can avoid interference from the magnetic lines of force of the electromagnetic coil and magnetic failure of the first magnetic part; if the distance between the first magnetic part and the electromagnetic coil is less than 20 mm, the first magnetic part will be too close to the cookware, and then due to interference from the magnetic lines of force of the electromagnetic coil, the magnetic failure of the first magnetic part will occur.

[0018] Furthermore, the upper panel is provided with an anti-slip silk screen, and at least a portion of the structure of the thermal insulation bracket contacts the anti-slip silk screen.

[0019] By adopting the above-mentioned technical solution, the surface friction of the upper panel is increased by setting an anti-slip silk screen on the upper panel to prevent the insulation bracket from sliding or moving during use, which can effectively enhance the stability and anti-slip performance of the insulation bracket placed on the upper panel.

[0020] Furthermore, an anti-skid suction cup is installed on the thermal insulation bracket, and the anti-skid suction cup is adsorbed on the upper panel.

[0021] By adopting the above-mentioned technical solution, the anti-slip suction cup installed on the thermal insulation bracket is adsorbed on the upper panel, thereby further enhancing the stability of the thermal insulation bracket placed on the upper panel and preventing the thermal insulation bracket from sliding during use.

[0022] Furthermore, a built-in temperature detection sensor is installed on the electromagnetic coil.

[0023] By adopting the above-mentioned technical solution, a built-in temperature detection sensor is installed on the electromagnetic coil, so that the induction cooker can be used normally even when the thermal insulation bracket is not installed, preventing the induction cooker from being unusable due to damage or loss of the thermal insulation bracket.

[0032] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0033] like Figures 1 to 4 As shown, the utility model provides an electromagnetic cooker, including a cooker body 5, the cooker body 5 includes an upper panel 1 and an electromagnetic coil 2 for heating a cooker 6, the electromagnetic coil 2 is arranged below the upper panel 1, the electromagnetic cooker also includes a heat insulation bracket 3, the upper panel 1 corresponds to the electromagnetic coil 2 to form a heating area 13, the heat insulation bracket 3 can be placed in the heating area and is used to carry the cooker 6, the heat insulation bracket 3 is installed with a wireless temperature detection component 4, the wireless temperature detection component 4 includes an energy receiving coil 41, a temperature detection sensor 42 and a wireless communication module 43 electrically connected to each other, the detection end of the temperature detection sensor 42 is close to the cooker 6, the horizontal projection of the energy receiving coil 41 is located within the horizontal projection range of the electromagnetic coil 2, so that the electromagnetic coil 2 can charge the energy receiving coil 41.

[0034] The utility model sets a heat-insulating bracket 3 between the upper panel 1 and the pot 6 to separate the bottom of the pot 6 from the upper panel 1, so as to avoid the temperature of the pot 6 being transferred to the upper panel 1 and causing high-temperature damage to the components below the upper panel 1 when the electromagnetic cooker is used for high-temperature stir-frying; and the wireless temperature detection component 4 set on the heat-insulating bracket 3 can detect the temperature of the pot 6 on the heat-insulating bracket 3, and transmit the temperature data to the control panel through the wireless communication module 43, so that the user can adjust it according to the temperature data, and because the wireless temperature detection component 4 is located on the heat-insulating bracket 3, the wireless temperature detection component 4 is closer to the pot 6, so that the wireless temperature detection component 4 can obtain the pot temperature closer to the actual data; wherein, because the horizontal projection of the energy receiving coil 41 provided in the wireless temperature detection component 4 is within the horizontal projection range of the electromagnetic coil 2, the energy receiving coil 41 can be completely placed within the alternating magnetic field range of the electromagnetic coil 2, which helps to improve the efficiency and reliability of wireless power transmission.

[0035] The heat insulating bracket 3 may be made of non-metallic materials such as polystyrene and silicate fiber, which have low thermal conductivity and good heat insulating properties.

[0036] In this embodiment, the electromagnetic coil 2 is arranged below the upper panel 1, with a certain distance between it and the upper panel 1, and an insulating cavity 21 is formed between the upper panel 1 and the electromagnetic coil 2, so as to prevent the temperature generated on the upper panel 1 from being directly transferred to the electromagnetic coil 2 and affecting the electromagnetic coil 2; in other embodiments, the electromagnetic coil 2 can also be close to the bottom of the panel.

[0037] Specifically, the insulation bracket 3 is also provided with an elastic member 35 for allowing the detection end of the temperature sensor 42 to fit and maintain fit with the bottom of the cookware 6. The detection end is supported by the elastic member 35 so that the detection end always maintains a close contact with the bottom of the cookware, thereby ensuring the accuracy of the temperature data. The elastic member 35 can be a suitable elastic member such as a compression spring, a torsion spring, or an elastic material member.

[0038] In this embodiment, in order to provide stable and sufficient energy to the wireless temperature detection component 4, the vertical distance between the electromagnetic coil 2 and the energy receiving coil 41 is set to 10mm. By setting the vertical distance between the electromagnetic coil 2 and the energy receiving coil 41 to 10mm, stable and sufficient energy can be provided to the energy receiving coil 41; it can be understood that in other embodiments, the vertical distance between the electromagnetic coil 2 and the energy receiving coil 41 can also be 7mm, 9mm, 12mm, 14mm, etc., which are suitable distances less than 15mm; if the vertical distance between the electromagnetic coil 2 and the energy receiving coil 41 is greater than 15mm, the electromagnetic field strength generated by the electromagnetic coil 2 will be weakened due to the excessive distance between the electromagnetic coil 2 and the energy receiving coil 41, resulting in the inability to effectively transmit energy to the energy receiving coil 41.

[0039] In this embodiment, in order to ensure the stability of the pot 6 on the heat-insulating support 3, the heat-insulating support 3 includes a center piece 31 and four spokes 32 radially distributed outward from the center piece 31. The four spokes 32 radially distributed outward from the center piece 31 can provide stable support for the pot 6 to prevent the pot 6 from sliding or tilting when placed on the heat-insulating support 3; of course, in other embodiments, the number of spokes 32 can also be greater than or less than four, such as three, five or six spokes, etc., as long as the stability of the pot 6 placed on the heat-insulating support 3 is ensured.

[0040] Specifically, in the present embodiment, the temperature detection sensor 42 is mounted on the center piece 31, and the energy receiving coil 41 is mounted on the spoke 32. Since the center of the bottom of the pot 6 is heated higher than the other positions during heating, by measuring the temperature of the center of the bottom of the pot 6, temperature data closer to the real data can be obtained, which is convenient for the user to control the heating temperature more accurately. At the same time, installing the energy receiving coil 41 on the spoke 32 can reduce the influence of the high temperature at the center of the bottom of the pot on the energy receiving coil 41.

[0041] It can be understood that in other embodiments, the number of wireless temperature detection components 4 can be multiple, and the wireless temperature detection components 4 are installed on at least two spokes 32. Through the wireless temperature detection components 4 installed on at least two spokes 32, the temperature of the entire bottom of the cookware can be evenly detected, so that the user can adjust the temperature as needed according to the obtained detection results.

[0042] In this embodiment, the thermal insulation bracket 3 is detachably connected to the upper panel 1 for easy replacement or storage. Specifically, a first magnetic component 11 is installed below the heating zone 13, and a second magnetic component 34 that can be magnetically attracted to the first magnetic component 11 is provided on the thermal insulation bracket 3; when the thermal insulation bracket 3 is placed in the circular heating zone 13, the first magnetic component 11 will cooperate with the second magnetic component 34 on the thermal insulation bracket 3, and realize automatic calibration by mutual attraction of magnetic force; at the same time, after the thermal insulation bracket 3 is placed in the heating zone 13, the horizontal projection of the energy receiving coil 41 can be located within the horizontal projection range of the electromagnetic coil 2, so that the electromagnetic coil 2 can charge the energy receiving coil 41. Of course, in other embodiments, multiple magnetic components can be provided to assist the user in placing the thermal insulation bracket 3 to a specified position.

[0043] In another embodiment, the thermal insulation bracket 3 can also be fixedly connected to the upper panel 1. No matter whether the thermal insulation bracket 3 is fixed to the upper panel 1 or detachably connected to the upper panel 1, when cooking, the thermal insulation bracket 3 placed in place can effectively prevent the pot 6 from directly contacting the upper panel 1.

[0044] In this embodiment, the first magnetic part 11 and the second magnetic part 34 are both magnets, and the ends of the two magnets with opposite magnetic properties are arranged relative to each other. When the two magnets attract each other, the centers of the magnets will align with each other, which can better perform automatic positioning; of course, in another embodiment, one of the first magnetic part 11 and the second magnetic part 34 is a magnet, and the other is a metal part that can be attracted by a magnet.

[0045] Among them, the horizontal projection of the first magnetic component 11 is located outside the horizontal projection range of the electromagnetic coil 2; by setting the horizontal projection of the first magnetic component 11 outside the horizontal projection range of the electromagnetic coil 2, it is away from the magnetic lines of force generated by the electromagnetic coil 2, thereby avoiding interference of the electromagnetic coil 2 on the first magnetic component 11, thereby causing the first magnetic component 11 to lose its magnetism.

[0046] In this embodiment, the distance between the first magnetic part 11 and the electromagnetic coil 2 is 25 mm; by setting the distance between the first magnetic part 11 and the electromagnetic coil 2 to 25 mm, the interference of the magnetic lines of force of the electromagnetic coil 2 can be avoided, which may cause the magnetic failure of the first magnetic part 11; it can be understood that in other embodiments, the distance between the first magnetic part 11 and the electromagnetic coil 2 can also be 22 mm, 24 mm, 27 mm, 29 mm or other distances greater than 20 mm; if the distance between the first magnetic part 11 and the electromagnetic coil 2 is less than 20 mm, the first magnetic part 11 will be too close to the electromagnetic coil 2, and then due to the interference of the magnetic lines of force of the electromagnetic coil 2, the magnetic failure of the first magnetic part 11 will occur.

[0047] Specifically, four anti-slip silk screens 12 are provided on the upper panel 1, and at least part of the structure of the thermal insulation bracket 3 contacts the anti-slip silk screen 12; by providing the anti-slip silk screen 12 on the upper panel 1, the surface friction of the upper panel 1 is increased to prevent the thermal insulation bracket 3 from sliding or moving during use, which can effectively enhance the stability and anti-slip performance of the thermal insulation bracket 3 placed on the upper panel 1.

[0048] Among them, four anti-slip suction cups 33 are installed on the thermal insulation bracket 3, and the thermal insulation bracket 3 is adsorbed on the upper panel 1 through the anti-slip suction cups 33; the anti-slip suction cups 33 installed on the thermal insulation bracket 3 are adsorbed on the upper panel 1, thereby further enhancing the stability of the thermal insulation bracket 3 placed on the upper panel 1 and preventing the thermal insulation bracket 3 from sliding during use.

[0049] In this embodiment, a built-in temperature detection sensor 22 is installed on the electromagnetic coil 2; by installing the built-in temperature detection sensor 22 on the electromagnetic coil 2, the induction cooker can be used normally even when the thermal insulation bracket 3 is not installed, thereby preventing the induction cooker from being unusable due to damage or loss of the thermal insulation bracket 3; of course, in another embodiment, when the thermal insulation bracket 3 is fixedly connected to the upper panel 1, the built-in temperature detection sensor 22 may not be installed, and the temperature can be detected by the wireless temperature detection component 4 on the thermal insulation bracket 3.

[0050] Specifically, in the present embodiment, two cooking positions are provided on the stove body 5 so that the user can heat two different pots 6 separately. An electromagnetic coil 2 is provided under each cooking position, and two thermal insulation brackets 3 are provided correspondingly. The user can choose whether to use the thermal insulation bracket 3 according to cooking needs; in other embodiments, only a single cooking position or multiple cooking positions are provided on the stove body 5, and the electromagnetic coil 2 and the thermal insulation bracket 3 are arranged correspondingly according to the number of cooking positions.

[0051] Specific control process: After the electromagnetic cooker is turned on, the electromagnetic coil 2 operates in the first n seconds to charge the energy receiving coil 41, and the wireless temperature detection component 4 is adapted to confirm whether there is a heat insulation bracket 3.

[0052] Without heat insulation bracket 3: The operation interface displays the normal heating mode. When the heating time reaches t1 or the temperature of the built-in temperature detection sensor reaches T1, the power is reduced by n levels, and the temperature of the temperature detection structure continues to rise by T2, T3...Tmax. The power continues to decrease until the temperature of the built-in temperature detection sensor stops rising to avoid overheating damage to the components.

[0053] With heat-insulating bracket 3: the operation interface displays the rapid heating mode until the protection temperature Tmax of the wireless temperature detection component 4 is reached, and the heating power drops to 0; when the wireless temperature detection component 4 is lower than the set protection temperature Tmax, the currently set power is restored for heating. Since the wireless temperature detection component 4 is arranged on the heat-insulating bracket 3 and is in close contact with the pot 6, the heating can be quickly restored.

[0054] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
