Technical field

The present application relates to the technical field of electromagnetic heating, and specifically to an electromagnetic heating device.

Background technique

In the related art, a multi-head stove is provided with multiple coil disks. In order to support the multiple coil disks, horizontal plates need to be installed to support the multiple coil disks. However, the panels used for positioning increase the production cost and assembly complexity of the product, and the panels also increase the weight of the entire machine.

Therefore, how to overcome the above technical defects has become an urgent technical problem to be solved.

Application content

This application aims to solve at least one of the technical problems existing in the prior art.

To this end, one aspect of the present application proposes an electromagnetic heating device.

In view of this, this application provides an electromagnetic heating device. The electromagnetic heating device includes: a frame, the frame is annular; a support beam, located inside the frame, both ends of the support beam are connected to the frame; a coil disk, one end is connected to the frame Connect the other end to the support beam.

The electromagnetic heating device as defined in this application includes a frame and a coil disk. Specifically, the frame is the main frame structure of the electromagnetic heating equipment and is used to position and support other working structures on the electromagnetic heating equipment. The frame is ring-shaped, and the working structure is set inside the frame. The coil disk is installed inside the frame. The coil disk can generate an electromagnetic field after being energized. The target container gradually heats up under the action of the electromagnetic field, thereby heating the food contained inside the high-temperature target container to cook the finished food. Among them, when the electromagnetic heating device is a multi-head stove, the number of coil disks is multiple, and the multiple coil disks need to be fixed at different predetermined installation positions in the frame.

In the related technology, in order to meet the technical requirement of fixing the coil disk, it is necessary to first set up a horizontal coil in the casing. Mounting plate, after which the coil disk is placed over the mounting plate to support and position the coil disk by the mounting plate. However, the size of the mounting plate that covers the entire internal space is large and consumes a lot of materials, which increases the cost of the product. Moreover, the mounting plate will significantly increase the weight of the product, which is not conducive to the lightweight design of the product, so that the practicality of the product is affected. .

In this regard, the electromagnetic heating equipment defined in this application is provided with a support beam. The support beam is installed inside the frame, and both ends of the support beam are fixed on the frame. After the assembly is completed, the support beam is installed horizontally in the space inside the frame. On this basis, the first end of the coil disk is connected to the frame, and the second end of the coil disk is connected to the support beam. After the installation of the coil disk is completed, the two ends of the coil disk are supported by the frame and the support beam respectively, and the middle section of the coil disk is suspended, so that the frame and the support beam jointly support the coil disk.

It can be seen that, unlike the technical solution of supporting the coil disk through a positioning plate, this application can reduce the materials used in the positioning and installation structure on the basis of meeting the coil disk positioning requirements by setting up support beams, thereby reducing the cost and weight of the electromagnetic heating equipment. . And compared with the technical solution of firmly installing panels on the inside of the frame, it is less difficult to install support beams on the inside of the frame, which can reduce the complexity of the assembly structure and further reduce the process complexity and production cost of the electromagnetic heating equipment. This overcomes the technical defects of heavy product weight and high cost existing in related technologies. This further achieves the technical effects of optimizing the positioning structure of the coil disk, improving the practicality of electromagnetic heating equipment, reducing the cost of electromagnetic heating equipment, and improving the competitiveness of product duration.

Specifically, the extension direction of the support beams inside the frame and the number of support beams installed inside the frame can be adjusted according to the distribution requirements of the coil disk and the size of the coil disk. In this technical solution, the number of support beams is not changed. And the extension direction of the support beam is rigidly limited, which can meet the basic requirement of co-locating the coil disk with the frame.

In addition, the above-mentioned electromagnetic heating equipment provided by this application may also have the following additional technical features:

In some technical solutions, optionally, the frame includes: two first sides, the two first sides are spaced apart, and the two ends of the support beam are respectively connected to the two first sides; two second sides, two second sides The two sides are spaced apart, and the first side and the second side are connected end to end to form a frame.

In this technical solution, the frame is rectangular, and the rectangular frame is enclosed by two first sides and two second sides. Wherein, the two first sides are parallel and opposite to each other, two ends of one second side are respectively connected to the first ends of the two first sides, and two ends of the other second side are respectively connected to the first ends of the two first sides. The two ends are connected, thereby enclosing a rectangular frame through the first side and the second side connected end to end. The two ends of the support beam are connected to the two A first side connection is made to demarcate a space on both sides of the support beam that can be used to position and install the coil disk. Specifically, the coil disks arranged on the left and right sides of the support beam can connect the first end to the first side, and the second end to the support beam. The first end of the coil disk can also be connected to the second side, and the second end of the coil disk can be connected to the second side. The two ends are connected to the support beam. In this technical solution, there is no hard limit on the installation method of the coil disk, which can meet the requirements of being distributed on the left and right sides of the support and supported by the support beam and the frame.

By connecting the two ends of the support beam to the opposite sides of the rectangular frame, it can provide convenient conditions for the array arrangement of coil disks when the electromagnetic heating equipment has multiple coil disks, so as to form multiple regular and evenly distributed heating areas. . Compared with the technical solution of connecting two adjacent sides through support beams, this support beam installation method can improve the strength of the overall structure composed of the frame and the support beams, and reduce the possibility of deformation of the rectangular frame during the installation of coil disks or during work. sex. This can achieve the technical effect of reducing the difficulty of coil disk layout and improving the reliability of electromagnetic heating equipment.

In some technical solutions, optionally, the support beam is spaced apart from the second side; one end of the coil disk is connected to the support beam, and the other end is connected to the second side.

In this technical solution, following the previous technical solution, the first side is the long side of the rectangular frame, the second side is the wide side of the rectangular frame, the support beam fixed between the two first sides and the two left and right sides Second side spacing. On this basis, the first end of the coil disk is fixed on the second side, the other end is fixed on the support beam, and the middle section of the coil disk is suspended between the second side and the support beam. It can be seen that this layout method can place the coil disk horizontally between the wide side of the rectangular frame and the support beam, so that the support beam can provide effective support for the coil disks on the left and right sides at the same time, thereby increasing the number of coil disks that can be arranged by the electromagnetic heating equipment. The number makes this structure more suitable for scenarios such as multi-burner stoves that require multiple coil disks.

In some technical solutions, optionally, two coil disks are formed into a group, and the two coil disks in the same group are symmetrically distributed.

In this technical solution, two coil disks are divided into one group, and the installation method of the two coil disks in the same group is explained. Specifically, two coil disks in the same group are symmetrically distributed on the left and right sides of the support beam, one of the coil disks is connected to the second side on the left side of the support beam, and the other coil disk is connected to the second side on the right side of the support beam. This arrangement can form symmetrically distributed heating areas on the electromagnetic heating device, similar to a conventional stove, thereby providing convenient conditions for users to cook food on two heating areas at the same time. In this way, the technical effects of improving the compactness of the coil disk arrangement, improving the practicality of the electromagnetic heating equipment, and improving the user experience can be achieved.

In some technical solutions, optionally, multiple sets of coil disks are included, and the multiple sets of coil disks are distributed along the extension direction of the support beam.

In this technical solution, following the previous technical solution, the electromagnetic heating equipment includes multiple sets of coil disks, wherein the multiple sets of coil disks are distributed along the extension direction of the support beam to form a coil disk array on the electromagnetic heating device. The number of rows in the array corresponds to the number of groups of coil disks, and the number of columns is constant at two. This arrangement can maximize the use of the inner space of the rectangular frame, thereby increasing the number of coil disks without changing the size of the frame. This will achieve the technical effect of improving the compactness of the electromagnetic heating equipment and providing convenient conditions for the miniaturization design of the electromagnetic heating equipment.

In some technical solutions, optionally, the coil disk is located on top of the support beam, and the support beam is used to support the coil disk.

In this technical solution, the support method provided by the support beam is explained. Specifically, the end of the coil disk is placed above the support beam to support the coil disk through the support beam to prevent the coil disk from collapsing due to its own weight. Correspondingly, the other end of the coil disk is placed above the frame, thereby supporting the coil disk through the frame and the support beam. Compared with the end-face connection method, placing the coil disk above the support beam can improve the positioning reliability of the coil disk and avoid the problem of the end-face joint structure being damaged due to the weight of the coil disk. At the same time, during the assembly process, the coil disk can be placed above the support beam and frame first, and the coil disk can be connected after moving to the predetermined position. Compared with the end-to-end connection method, the structural layout proposed by this technical solution It can reduce the difficulty of disassembly and assembly of the coil plate, thereby improving the production efficiency of the electromagnetic heating component and reducing the difficulty of maintaining the electromagnetic heating component.

In some technical solutions, optionally, the support beam is a plate member, and the long side of the support beam is bent in a direction away from the coil disk to form a folded edge.

In this technical solution, the support beam is a plate member, and the support beam can be prepared by casting or stamping process. Among them, the long sides of the support beam, that is, the left and right sides of the support beam, are bent in the direction away from the coil disk. Taking the coil disk placed above the support beam in the aforementioned technical solution as an example, the left and right long sides of the support beam are bent in the direction away from the coil disk. Bend the bottom to form a hem in the same direction as the support beam extends.

By constructing folded edges, the bending and torsion resistance of the support beam can be improved, preventing the support beam from bending or even breaking under the gravity of multiple coil disks, thereby improving the structural strength of the support beam, improving the reliability of electromagnetic heating components, and reducing product failures. efficiency technical effects.

In some technical solutions, optionally, the support beam is cut through a plane perpendicular to the extension direction of the support beam, The folded edge is circular in cross-section.

In this technical solution, the shape of the folded edge is limited. Specifically, the cross section of the support beam can be obtained by cutting the support beam with a plane perpendicular to the length direction of the support beam. In this section, the downwardly bent flanges at both ends of the support beam are circular to form columnar flanges. The possibility of stress concentration on the columnar flange is low, and the bending and torsion resistance of the flange can be further enhanced by limiting the cross-sectional shape of the flange to a circle to ensure that the support beam can withstand the weight of multiple coil disks. This will achieve the technical effect of improving the structural strength of the support beam and reducing the failure rate of the support beam.

In some technical solutions, optionally, the diameter of the flange ranges from greater than or equal to 6 mm to less than or equal to 12 mm.

In this technical solution, the size of the columnar flange is limited. Specifically, the diameter of the columnar flange needs to be greater than or equal to 6 mm. By limiting the diameter of the columnar flange to greater than or equal to 6mm, it can be avoided that the columnar flange is too small to withstand the weight of multiple coil disks, thereby ensuring that the support beam will not bend or even bend. fracture.

Furthermore, the execution of the columnar flanging needs to be less than or equal to 12mm. By limiting the diameter of the columnar flange to less than or equal to 12mm, the encroachment of the columnar flange on the space below the support beam can be reduced on the basis of meeting the bending and torsion resistance requirements, and the columnar flanging can be reduced. The possibility of interference with the bottom electrical structure prevents the product size from being forced to increase due to excessive folding size. At the same time, limiting the diameter of the columnar flange to less than or equal to 12mm can also reduce the use of materials, thereby reducing the weight and cost of the support beam. This can achieve the technical effect of improving the reliability of the support beam, reducing the production cost of the support beam, and providing convenient conditions for the miniaturization and lightweight design of electromagnetic heating equipment.

In some technical solutions, optionally, the support beam includes a mounting hole, and the coil disk part is inserted into the mounting hole.

In this technical solution, the support beam is provided with a mounting hole that passes through the support beam up and down, and the bottom of the coil plate is provided with a protruding portion that matches the shape of the mounting hole. When assembling the coil disk, align and insert the protrusions into the mounting holes. Correspondingly, the frame is also provided with a socket, and the protruding portion at the bottom of the other end of the coil disk is plugged into the socket, thereby accurately positioning the coil disk at the predetermined installation position. This positioning structure has the advantage of low complexity, convenient disassembly and assembly, and can greatly reduce the difficulty of assembly and maintenance of the coil disk.

Furthermore, the protruding portion has an interference fit with the mounting hole on the support beam, and the protruding portion has an interference fit with the socket on the frame. By setting this interference fit relationship, the coil disk can be prevented from being dislocated during the working process, and the coil disk can be prevented from being dislocated during operation. Abnormal noise occurs in the coil disk, thereby achieving the technical effect of improving the positioning accuracy of the coil disk.

In some technical solutions, optionally, the electromagnetic heating equipment also includes: a limit table, connected to the frame; a positioning column, provided on the limit table; a positioning hole, provided on the support beam, sleeved on the positioning column, and the support beam Contact with the limiter.

In this technical solution, the connection structure between the support beam and the frame is explained. Specifically, a limiting platform is provided on the inner ring surface of the frame, and a positioning post is provided on the top of the limiting platform. Correspondingly, the end of the support beam is provided with positioning holes whose size matches the positioning column. During the assembly process, align the positioning hole with the positioning column and press down on the support beam so that the support beam is sleeved on the positioning column until the bottom surface of the support beam contacts the upper end surface of the limiter to complete the pre-assembly of the support beam. , and then fix the support beam on the limiting platform through screws and other connectors.

Compared with the technical solution of connecting the end face of the support beam to the inside of the frame, the limiting platform located under the support beam can provide support for the support beam, thereby preventing the support beam carrying the weight of the coil disk from falling off the frame. At the same time, this structure has the advantages of low structural complexity and easy disassembly and assembly, which is conducive to improving production efficiency and reducing maintenance difficulty.

In some technical solutions, optionally, the support beam includes a groove, and the positioning hole is located in the groove.

In this technical solution, the end of the support beam is provided with a groove, and the groove is recessed in a direction away from the coil disk. Specifically, the groove can be formed through a stamping process. On this basis, the positioning hole is set in the groove, that is, the contact area between the limiting platform and the support beam is located at the bottom of the groove. By providing a sunken groove, the structural strength of the support beam that is lifted by the groove and in contact with the limiting platform can be improved. Specifically, the inclined side wall of the groove resists the weight of the coil disk to reduce the possibility of collapse of the support beam. This will achieve the technical effect of optimizing the structural strength of the support beam and improving the reliability of the electromagnetic heating equipment.

In some technical solutions, optionally, the electromagnetic heating equipment also includes: a bottom plate, connected to the frame, located at the bottom of the support beam and coil pan.

In this technical solution, the electromagnetic heating equipment is also provided with a bottom plate, which is connected to the frame and used to cover the opening at the bottom of the annular frame. The frame and bottom plate enclose a cavity, and electrical devices such as controllers and circuit boards are placed in the cavity to protect the electrical devices through the bottom plate and frame and reduce the probability of damage to the electrical devices.

In some technical solutions, optionally, the bottom plate is spaced apart from the support beam; the bottom plate is spaced apart from the coil disk.

In this technical solution, the bottom plate is spaced apart from the support beam, and the coil disk is spaced apart from the bottom plate. That is, the middle sections of the support beam and coil disk are suspended in the air. Under this structural layout, there is an installation space under the support beam and coil disk, and the power supply circuit and control circuit connected to the coil disk can be arranged, thereby improving the structural compactness of the electromagnetic heating equipment. Compactness, the technical effect of reducing the size of electromagnetic heating equipment.

In some technical solutions, optionally, the electromagnetic heating device also includes: a panel connected to the frame and located on the top of the coil plate.

In this technical solution, the electromagnetic heating device also includes a panel, which is disposed above the side plate and is used to cover the opening at the top of the frame to hide the working structure inside the frame. On the other hand, the panel is used to support the target container. The coil disk in the frame forms a heating area on the panel. The target container is placed above the heating area. Under the action of the electromagnetic field generated by the coil disk, the target container gradually heats up to pass through Cooks the ingredients inside at high temperatures.

The electromagnetic heating device 100 includes: a frame 110, which is annular; a support beam 120, which is located inside the frame 110 and supports Both ends of the beam 120 are connected to the frame 110; one end of the coil disk 130 is connected to the frame 110, and the other end is connected to the support beam 120.

The electromagnetic heating device 100 defined in this application includes a frame 110 and a coil disk 130 . Specifically, the frame 110 is the main frame 110 structure of the electromagnetic heating device 100 and is used to position and support other working structures on the electromagnetic heating device 100 . The frame 110 is ring-shaped, and the working structure is arranged inside the frame 110 . The coil disk 130 is installed inside the frame 110. The coil disk 130 can generate an electromagnetic field after being energized. The target container gradually heats up under the action of the electromagnetic field, thereby heating the food contained inside the high-temperature target container to cook the finished food. When the electromagnetic heating device 100 is a multi-head stove, the number of coil disks 130 is multiple, and the multiple coil disks 130 need to be fixed at different predetermined installation positions in the frame 110 .

In the related art, in order to meet the technical requirement of fixing the coil disk, it is necessary to first set up a horizontal mounting plate in the casing, and then place the coil disk above the mounting plate to support and position the coil disk through the mounting plate. However, the size of the mounting plate that covers the entire internal space is large and consumes a lot of materials, which increases the cost of the product. Moreover, the mounting plate will significantly increase the weight of the product, which is not conducive to the lightweight design of the product, so that the practicality of the product is affected. .

In this regard, the electromagnetic heating equipment 100 defined in this application is provided with a support beam 120.

It can be seen that, unlike the embodiment in which the coil disk 130 is supported by a positioning plate, in this application, by providing the support beam 120, the material used in the positioning and installation structure can be reduced on the basis of meeting the positioning requirements of the coil disk 130, so as to reduce the cost of the electromagnetic heating device 100. cost and weight. And compared with the embodiment in which the panels are firmly installed inside the frame 110, it is less difficult to install the support beam 120 inside the frame 110, which can reduce the complexity of the assembly structure and further reduce the process complexity of the electromagnetic heating device 100. and production costs. This overcomes the technical defects of heavy product weight and high cost existing in related technologies. This further achieves the technical effects of optimizing the positioning structure of the coil disk 130, improving the practicality of the electromagnetic heating equipment 100, reducing the cost of the electromagnetic heating equipment 100, and improving the competitiveness of the product's duration.

Specifically, the extension direction of the support beams 120 inside the frame 110 and the number of support beams 120 installed inside the frame 110 can be adjusted according to the distribution requirements of the coil disk 130 and the size of the coil disk 130.

The two first sides 112 are parallel and opposite to each other, two ends of one second side 114 are respectively connected to the first ends of the two first sides 112 , and two ends of the other second side 114 are respectively connected to the two second sides 112 . The second end of the side 112 is connected, so that the rectangular frame 110 is enclosed by the first side 112 and the second side 114 connected end to end. Both ends of the support beam 120 are respectively connected to the two first sides 112 to define a space on both sides of the support beam 120 that can be used to position and install the coil disk 130 . Specifically, the coil disks 130 arranged on the left and right sides of the support beam 120 can connect the first end to the first side 112 and the second end to the support beam 120. The first end of the coil disk 130 can also be connected to the second side. Edge 114 connects the second end to support beam 120 .

The middle section of the coil disk 130 is suspended between the second side 114 and the support beam 120 . It can be seen that this layout can place the coil disk 130 horizontally between the wide side of the rectangular frame 110 and the support beam 120, so that the support beam 120 can provide effective support for the coil disk 130 on the left and right sides at the same time, thereby increasing the number of electromagnetic heating devices 100. The number of coil disks 130 that can be arranged makes this structure more suitable for scenarios such as multi-burner stoves where multiple coil disks 130 need to be installed.

This arrangement can form symmetrically distributed heating areas on the electromagnetic heating device 100, similar to a conventional stove, thereby providing convenient conditions for users to cook food on two heating areas at the same time. This achieves technical effects of improving the compactness of the coil disk 130 arrangement, improving the practicality of the electromagnetic heating device 100, and improving the user experience.

In some embodiments, optionally, multiple sets of coil disks 130 are included, and the multiple sets of coil disks 130 are supported along The extension direction of the beam 120 is distributed.

The number of rows in the array corresponds to the number of groups of coil disks 130, and the number of columns is always two. This arrangement can maximize the use of the inner space of the rectangular frame 110, thereby increasing the number of coil disks 130 without changing the size of the frame 110. This achieves the technical effect of improving the structural compactness of the electromagnetic heating device 100 and providing convenient conditions for the miniaturization design of the electromagnetic heating device 100 .

As shown in FIGS. 2 and 5 , in some embodiments, the coil disk 130 is optionally located on top of the support beam 120 , and the support beam 120 is used to support the coil disk 130 .
