Referring to fig. 1, a cooker body 100 of the electric cooker includes a housing 10, an outer pot 20, an inner pot 30, a coil disk 40, a temperature sensing assembly 50, and the like.
The upper end of the housing 10 is provided with an opening for installing other parts such as the outer pot 20, the inner pot 30, the coil panel 40, the temperature sensing assembly 50, etc. In the present embodiment, the housing 10 includes a base (not shown), a case 11, and a case cover 12; the casing 11 is in a barrel shape with an upper opening and a lower opening, the lower end of the casing 11 is in butt joint with the upper end of the base, the upper end of the casing 11 is in butt joint with the lower end of the casing cover 12 in an annular shape, so that the casing 11, the base and the casing cover 12 together enclose a cavity, and the outer pot 20, the inner pot 30, the coil panel 40, the temperature sensing assembly 50 and other components are all arranged in the cavity.
The outer pot 20 is provided in a tub shape with upper and lower openings, and is installed in the housing 11, and specifically, the upper end of the outer pot 20 is fixedly connected to the housing cover 12, which is used to separate the inner pot 30 from the housing 11. It should be noted that, the outer pot 20 is generally made of heat insulation materials, so that on one hand, heat of the inner pot 30 is prevented from being conducted to the outer shell 11 after being heated, and the outer shell 11 is prevented from being deformed, on the other hand, heat loss of the inner pot 30 can be effectively controlled, and working efficiency of the electric cooker is ensured.
The coil panel 40 is installed in the housing 10, and is mainly used for winding the coil, and the coil panel 40 may be plate-shaped, flat concave, pure concave or other shapes, and is not limited herein. In the embodiment of the present invention, the coil panel 40 is disposed in a flat concave shape, specifically, the coil panel 40 has a panel bottom 41 disposed in a plate shape and an annular side portion 42 extending upward from the periphery of the panel bottom 41, and the upper end of the annular side portion 42 is disposed adjacent to the lower end of the outer pan 20, so that the coil panel 40 and the outer pan 20 together form a cavity for accommodating the inner pan 30, and the shape and the size of the cavity are adapted to the shape and the size of the inner pan 30 respectively, so that the inner pan 30 can be more firmly accommodated in the housing 10.
It should be noted that, the coil bottom 41 and the annular side portion 42 of the coil disc 40 may be used for winding coil windings, that is, the coil windings wound on the coil bottom 41 may heat the bottom of the inner pot 30, the coil windings wound on the annular side portion 42 may heat the side wall of the inner pot 30, so that the area of the coil disc 40 for winding coil windings is increased, and the heating area of the inner pot 30 is increased, so that the working efficiency of the electric cooker is improved.
The temperature sensing assembly 50 is mounted on the coil panel 40, specifically, a mounting hole 411 is formed in the middle of the panel bottom 41 of the coil panel 40, the temperature sensing assembly 50 is mounted in the mounting hole 411, and the upper end of the temperature sensing assembly 50 extends out from the upper end of the mounting hole 411 to be abutted with the bottom of the inner pan 30.
Because the shape and the size of the inner pot 30 are easy to deviate when the inner pot 30 is manufactured, when the inner pot 30 is placed in the shell 10, the temperature sensing component 50 cannot be abutted with the bottom of the inner pot 30, and the temperature sensing component 50 is not directly contacted with the bottom of the inner pot 30, so that the problem of inaccurate temperature measurement of the temperature sensing component 50 can occur. In order to solve the above-mentioned problem, in the embodiment of the present invention, the coil panel 40 is movably installed in the housing 10 in the up-down direction; and a magnetic attraction assembly is also provided between the coil disk 40 and the inner pan 30, the magnetic attraction assembly including a first magnetic attraction portion 70 provided on the coil disk 40, and a second magnetic attraction portion provided on the inner pan 30. The magnetic properties of the first magnetic attraction portion 70 and the second magnetic attraction portion are different, that is, if the first magnetic attraction portion is an S pole, the second magnetic attraction portion is an N pole; if the first magnetic attraction part is an N pole, the second magnetic attraction part is an S pole; of course, at least one of the first magnetic attraction portion 70 and the second magnetic attraction portion may have a magnetic attraction effect, and is not particularly limited herein, and when the distance between the first magnetic attraction portion 70 and the second magnetic attraction portion is sufficiently small, the first magnetic attraction portion 70 and the second magnetic attraction portion can generate a magnetic attraction effect.
When the inner pot 30 is placed in the housing 10, since the interval between the inner pot 30 and the coil disk 40 is relatively small, the first magnetic attraction portion 70 mounted on the coil disk 40 and the second magnetic attraction portion mounted on the inner pot 30 can generate magnetic attraction, so that the coil disk 40 and the inner pot 30 are close to each other. Since the rim of the inner pot 30 is abutted against the outer shell 12 of the housing 10, the inner pot 30 cannot move downward, and therefore, only the coil disc 40 moves upward when the first magnetic attraction portion 70 and the second magnetic attraction portion are magnetically attracted; at this time, the temperature sensing assembly 50 mounted on the coil panel 40 moves upward along with the coil panel 40, so that the space between the temperature sensing assembly 50 and the bottom of the inner pot 30 is reduced, and the temperature sensing assembly 50 is in direct contact with the bottom of the inner pot 30, so that the detection accuracy of the temperature sensing assembly 50 is improved.
In addition, the distance between the inner pot 30 and the coil panel 40 can be adjusted by the first magnetic attraction part 70 and the second magnetic attraction part, so that the cooker body 100 of the electric cooker can be suitable for inner pots of different types, and the application range of the cooker body 100 of the electric cooker is further enlarged.
According to the invention, the coil panel 40 is movably arranged in the shell 10 along the up-down direction, the first magnetic attraction part 70 of the magnetic attraction component is arranged on the coil panel 40, and the second magnetic attraction part of the magnetic attraction component is arranged on the inner pot 30, so that the magnetism of the first magnetic attraction part 70 and the magnetism of the second magnetic attraction part are different, when the inner pot 30 is arranged in the shell 10 and above the coil panel 40, the first magnetic attraction part 70 arranged on the coil panel 40 and the second magnetic attraction part arranged on the inner pot 30 can generate a magnetic adsorption effect, so that the coil panel 40 and the inner pot 30 are mutually close, and the temperature sensing component 50 arranged on the coil panel 40 moves upwards along with the coil panel 40, so that the temperature sensing component 50 arranged on the coil panel 40 can be abutted with the bottom of the inner pot 30, and the temperature sensing precision of the temperature sensing component 50 is favorably improved, and the temperature sensing precision of the electric cooker is favorably improved.
The first magnetic attraction part 70 may be mounted on the bottom 41 of the coil disk 40 or may be mounted on the annular side 42 of the coil disk 40; the second magnetic attraction part is arranged corresponding to the mounting position of the first magnetic attraction part 70, namely, when the first magnetic attraction part 70 is mounted on the bottom 41 of the coil panel 40, the second magnetic attraction part is mounted on the bottom of the inner pot 30, and when the first magnetic attraction part 70 is mounted on the annular side part 42 of the coil panel 40, the second magnetic attraction part is mounted on the side wall of the inner pot 30. In the embodiment of the present invention, the first magnetic attraction portion 70 is mounted to the bottom 41 of the coil disk 40, and correspondingly, the second magnetic attraction portion is mounted to the bottom of the inner pan 30. Since the magnetic attraction capability of the first magnetic attraction portion 70 and the second magnetic attraction portion is not limited by the installation positions thereof, that is, the first magnetic attraction portion 70 may be disposed on the upper surface of the coil disk 40, or may be disposed on the lower surface of the coil disk 40, or the second magnetic attraction portion may be disposed on the lower surface of the bottom of the inner pan 30, or may be disposed on the upper surface of the bottom of the inner pan 30, which is not particularly limited herein.
In order to ensure that the first magnetic attraction portion 70 and the second magnetic attraction portion can generate the magnetic attraction effect, in the embodiment of the present invention, the first magnetic attraction portion 70 is disposed on the upper surface of the disc bottom 41 of the coil disc 40. Because the upper surface of the bottom 41 of the coil 40 directly faces the bottom of the inner pot 30, the distance between the first magnetic attraction part 70 and the second magnetic attraction part is reduced, the magnetic attraction effect of the first magnetic attraction part 70 on the coil 40 and the second magnetic attraction part on the inner pot 30 is ensured, the coil 40 is upwards close to the inner pot 30 under the magnetic attraction effect of the first magnetic attraction part 70 and the second magnetic attraction part, and the temperature sensing assembly 50 arranged on the coil 40 is ensured to be in direct contact with the bottom of the inner pot 30. Because no gap exists between the temperature sensing assembly 50 and the bottom of the inner pot 30, the temperature sensing assembly 50 can directly detect the real-time temperature of the bottom of the inner pot 30, so that the temperature measuring precision of the temperature sensing assembly 50 is improved, and the temperature measuring precision of the electric cooker is improved.
It should be noted that, since the inner pot 30 is generally made of a metal material, the second magnetic attraction portion may be formed by the inner pot 30 itself, so that the setting and installation of the second magnetic attraction portion are omitted.
Since the second magnetic attraction portion is formed of the inner pot 30 made of a metal material, the first magnetic attraction portion 70 must be formed of a magnet having a magnetic attraction effect. In order to facilitate the fixed installation of the first magnetic attraction portion 70, in the embodiment of the present invention, the upper surface of the disc bottom 41 of the coil disc 40 is provided with the installation groove 412, and the installation groove 412 is used for the fixed installation of the first magnetic attraction portion 70, that is, when the first magnetic attraction portion 70 is assembled with the coil disc 40, only the first magnetic attraction portion 70 needs to be embedded in the installation groove 412, so that the assembly and the disassembly of the first magnetic attraction portion 70 and the coil disc 40 are facilitated.
Further, the mounting groove 412 on the bottom 41 extends along the circumferential direction of the bottom 41, and can be used for mounting the first magnetic attraction portion 70 in an annular shape, so that the magnetic attraction area of the first magnetic attraction portion 70 and the bottom of the inner pot 30 is increased, the bottom of the inner pot 30 and the bottom 41 of the coil 40 are ensured to approach each other under the magnetic attraction effect of the first magnetic attraction portion 70 and the second magnetic attraction portion, and the temperature sensing assembly 50 on the coil 40 is ensured to be in contact with the bottom of the inner pot 30.
It should be noted that, the first magnetic attraction portion 70 may be a complete ring-shaped magnet, or may be formed by splicing multiple segments of arc magnets, which is not limited herein.
The mounting groove 412 may be formed as a groove recessed in the upper surface of the bottom 41, or may be defined by two ribs 413 protruding from the upper surface of the bottom 41, and is not particularly limited herein. In the embodiment of the present invention, the mounting groove 412 is defined by two ribs 413 protruding on the upper surface of the bottom 41, specifically, referring to fig. 3, two ribs 413 extending along the circumferential direction of the bottom 41 and disposed at intervals in the radial direction of the bottom 41 are protruding on the upper surface of the bottom 41, and the two ribs 413 and the bottom 41 together form the mounting groove 412 for mounting the first magnetic attraction portion 70.
When the first magnetic part 70 is mounted in the mounting groove 412, the two ribs 413 cooperate to hold and fix the first magnetic part 70, so that the first magnetic part 70 is convenient to fix, and the use of glue for bonding the first magnetic part 70 is omitted. In addition, the arrangement of the two convex ribs 413 also enhances the strength of the tray bottom 41 of the coil tray 40, so that the problem that the coil tray 40 is damaged due to impact in the process of carrying or transporting the electric rice cooker is avoided.
In order to facilitate the connection between the coil disc 40 and the housing 10, in the embodiment of the present invention, referring to fig. 2, the coil disc 40 is provided with a plurality of mounting platforms 421 disposed at intervals along the circumferential direction thereof, specifically, the plurality of mounting platforms 421 are disposed at the upper end of the annular side portion 42, and each mounting platform 421 is provided with a relief through hole 421a penetrating in the up-down direction; the inner surface of the casing 10 is correspondingly provided with a plurality of downward extending bosses 121, specifically, the bosses 121 extend downward from the inner surface of the casing cover 12, and the lower end of each boss 121 is located right above a mounting table 421 and is arranged at an interval from the mounting table 421 up and down; when the coil disk 40 is assembled with the housing 10, each mounting plate 421 is connected with each boss 121 through a connecting member 80.
Specifically, referring to fig. 4, the connecting member 80 passes through the yielding hole 421a on the mounting table 421 from bottom to top and is fixedly connected with the boss 121 on the mounting table 421, at this time, the upper end of the connecting member 80 is fixedly connected with the lower end of the mounting table 421, and the lower end of the connecting member 80 limits the mounting table 421, so that the coil panel 40 is suspended below the bosses 121. And since the connection member 80 is clearance-fitted with the relief through hole 421a of the mounting table 421, that is, the outer diameter of the connection member 80 is smaller than the aperture of the relief through hole 421a, the coil disk 40 can be moved up and down along the connection member 80.
Further, each of the above-mentioned connectors 80 includes a limiting portion 81, a guide section 82 connected to the limiting portion 81, and a thread section 83 extending from the guide section 82 in a direction away from the limiting portion 81, wherein an outer diameter of the guide section 82 is set larger than an outer diameter of the thread section 83 and smaller than an outer diameter of the limiting portion 81, and a length of the guide section 82 is set larger than a thickness of the mounting table 421.
When the coil panel 40 is connected with the housing 10, the screw thread of the connecting piece 80 and the guide section 82 pass through the yielding through hole 421a on the mounting table 421, the screw thread section 83 passing through the yielding through hole 421a is in threaded connection with the lower end of the boss 121, and the connection of the guide section 82 and the screw thread section 83 is in abutting connection with the lower end of the boss 121, so that the consistency of the screw thread connection length of each connecting piece 80 and the boss 121 is ensured, and the problem that the coil panel 40 cannot normally move due to the inconsistency of the screw thread connection length of one or more of the connecting pieces 80 and the boss 121 is avoided. The connection part of the guide section 82 and the limit part 81 is abutted against the lower end of the mounting table 421, so that the coil panel 40 is suspended below the bosses 121 through the connectors 80; since the length of the guide section 82 is greater than the thickness of the mounting table 421 and the guide section 82 is in clearance fit with the relief through hole 421a, the mounting table 421 can move between the boss 121 and the limiting portion 81, and the coil panel 40 can move up and down relative to the housing 10.
In order to make the coil disc 40 move more smoothly up and down, in an embodiment of the present invention, referring to fig. 2 and 4, an annular limiting rib 422 disposed around the yielding hole 421a is protruding from the upper surface of the mounting table 421. When the coil panel 40 is connected with the housing 10, the annular limiting rib 422 is sleeved at the lower end of the boss 121, so that when the coil panel 40 moves up and down along the plurality of connecting pieces 80, the annular limiting rib 422 also moves up and down relative to the boss 121, and due to the limiting of the annular limiting rib 422, the boss 121 can play a guiding role when the coil panel 40 moves up and down, and further the coil panel 40 can move up and down more stably.
In addition, since the mounting platforms 421 on the coil panel 40 are arranged at intervals along the circumferential direction of the coil panel 40, that is, the plurality of annular limiting ribs 422 are also arranged at intervals along the circumferential direction of the coil panel 40, each annular limiting rib 422 is sleeved at the lower end of the corresponding boss 121 when the coil panel 40 is movably connected with the housing 10, so that the coil panel 40 can be acted by the plurality of bosses 121 and the plurality of annular limiting ribs 422 when moving up and down, and the arrangement can ensure the stability of the coil panel 40 moving up and down.
Further, the inner wall surface of the annular stopper rib 422 is provided with a plurality of reinforcing ribs 423 extending vertically, and the plurality of reinforcing ribs 423 are spaced apart from each other in the circumferential direction of the annular stopper rib 422. The arrangement of the plurality of reinforcing ribs 423 reduces the contact area between the annular limiting rib 422 and the boss 121, so that the friction between the annular limiting rib 422 and the boss 121 is reduced due to the reduction of the contact area, and the annular limiting rib 422 moves up and down more smoothly relative to the boss 121; on the other hand, the strength of the annular stopper rib 422 can also be enhanced.
Further, the upper end of each of the reinforcing ribs 423 is provided with a chamfer, and the chamfer is arranged, so that the opening of the upper end of the annular space formed by surrounding the plurality of reinforcing ribs 423 is larger, and the boss 121 is conveniently inserted between the plurality of reinforcing ribs 423, namely, the chamfer is arranged at the upper end of the reinforcing rib 423, so that the boss 121 can be conveniently inserted between the plurality of reinforcing ribs 423, and the coil panel 40 is conveniently installed.
It should be noted that, in the embodiment of the present invention, the connection member 80 is made of a metal material, and is located on the mounting table 421 at the periphery of the coil panel 40, and since the coil winding is wound on the coil panel 40, the coil winding generates a magnetic field that changes at a high speed when the alternating current is applied, so that the connection member 80 is also in the magnetic field that changes at a high speed, which further causes the connection member 80 to generate an eddy current effect. Since the coil panel 40 is made of plastic, the mounting table 421 disposed at the periphery of the coil panel 40 is generally integrally formed with the coil panel 40, that is, the mounting table 421 is also made of plastic, when the connecting member 80 generates eddy effect and generates heat, the mounting table 421 is affected by the connecting member 80 first, thus the mounting table 421 is heated to deform, and further the yielding through hole 421a deforms, once the yielding through hole 421a deforms, the mounting table 421 is fixedly connected with the connecting member 80, and the coil panel 40 cannot move up and down along the connecting member 80.
In order to avoid the connection piece 80 being affected by the energized coil winding, in the embodiment of the present invention, the pot body 100 of the electric cooker is further provided with a magnetism isolating ring 90, specifically, referring to fig. 4 and 5, the upper end of the magnetism isolating ring 90 is fixedly connected with the periphery of the coil panel 40, the lower end of the magnetism isolating ring 90 extends downward, and the magnetism isolating ring 90 is installed on the outer side of the coil panel 40. Because the magnetism isolating ring 90 has good magnetism isolating effect, the parts of the cooker body 100 of the electric cooker positioned outside the magnetism isolating ring 90 are not affected by the electrified coil winding on the coil panel 40, and the parts positioned outside the magnetism isolating ring 90 can work normally.
Preferably, the magnetic shielding ring 90 is located at the outer side of the coil panel 40 and located at the inner sides of the plurality of connecting pieces 80, so that the plurality of connecting pieces 80 located at the outer side of the magnetic shielding ring 90 are not affected by the coil windings energized on the coil panel 40, that is, the connecting pieces 80 connecting the boss 121 and the mounting table 421 do not generate eddy current effects, thereby avoiding the problems that the mounting table 421 and the boss 121 are deformed due to heat generated by the connecting pieces 80 or the connecting pieces 80 are directly separated from the boss 121.
The upper end of the magnetism isolating ring 90 may be embedded in the coil panel 40, or may be connected and fixed to the coil panel 40 by a fixing member. In an embodiment of the present invention, the upper end of the magnetic isolation ring 90 is further provided with a plurality of mounting plates 91 distributed at intervals along the circumferential direction of the magnetic isolation ring 90 and extending along the radial direction of the magnetic isolation ring 90, and each mounting plate 91 is provided with a relief hole.
When the magnetism isolating ring 90 is assembled with the coil panel 40, each mounting plate 91 on the magnetism isolating ring 90 is fixedly connected with the mounting table 421 through a connecting piece 80, namely, the connecting piece 80 firstly passes through a yielding hole on the mounting plate 91 and then passes through a yielding through hole 421a on the mounting table 421 to be connected and fixed with the boss 121, so that the number of the connecting pieces 80 is reduced, and the production cost of the cooker body can be reduced.
In order to ensure that the temperature sensing assembly 50 on the coil panel 40 can be abutted against the bottom of the inner pot 30, in an embodiment of the present invention, referring to fig. 6, the lower end of the outer pot 20 of the pot body is spaced from the coil panel 40 in the vertical direction, that is, the lower end of the outer pot 20 is spaced from the upper end of the annular side portion 42 of the coil panel 40 in the vertical direction, and since a gap exists between the upper end of the annular side portion 42 of the coil panel 40 and the lower end of the outer pot 20, it is ensured that the coil panel 40 is not interfered by the outer pot 20 when moving in the vertical direction, so that the temperature sensing assembly 50 on the coil panel 40 can be abutted against the bottom of the inner pot 30, and further, the detection accuracy of the temperature sensing assembly 50 is advantageously improved.
The invention also provides an electric cooker, which comprises a cover body and a cooker body of the electric cooker, wherein the specific structure of the cooker body refers to the embodiment, and the electric cooker at least has all the beneficial effects brought by the technical proposal of the embodiment because the electric cooker adopts all the technical proposal of the embodiment, and is not repeated herein.
