Abstract
The utility model relates to a wire coil of an induction cooker, comprising a thermistor mount, a copper coil, a coil support and a magnetic stripe, wherein the coil support is round approximately and the center of the coil support is provided with a hole; the thermistor mount is arranged in the hole; the magnetic stripe is arranged at the lower surface of the coil support along the radial direction of the coil support; the copper coil is arranged on the upper surface of the coil support; and the center of the copper coil is an air hole. The inner circle of the copper coil winds until 2/3 of the total diameter of the wire coil to enlarge the diameter of the inner circle of the wire coil. When the wire coil is electrified, the intensity of the magnetic field in the middle of the wire coil is greatly reduced due to the increase of space, so is the magnetic-field interference in a thermistor in the middle. Therefore, the thermistor can accurately measure the temperature of a boiler above.
Description
Technical field
The utility model relates to a kind of electromagnetic oven assembly, the particularly a kind of electromagnetic oven wire coil that can accurately measure the electromagnetic oven temperature; Belong to family life articles for use technical field.
Background technology
Drum is a critical component in electromagnetic oven, produces serial or parallel connection resonance by drum and miscellaneous part when work, produces the alternating magnetic field of a 20～30KHZ above drum, and when cooking pot tool placed this magnetic field, pan can be responded to heating voluntarily.In addition, design has a NTC thermistor in the middle of the drum, is close to the microcrystal glass plate of top, in order to the temperature of detecting pan, and signal feedback size by the Single-chip Controlling heating power behind the single-chip microcomputer is realized the pan temperature controlling.The art designs of existing drum all concentrates on optimization magnetic field and raises the efficiency/reduce directions such as copper cash heating, but but ignored drum itself to being in the interference of the middle thermistor of drum, cause the thermistor detected temperatures inaccurate, thereby caused the inaccurate situation of electromagnetic oven temperature control.
Drum is such to the interference of thermistor: the heating principle of electromagnetic oven is that the pan to irony heats behind the drum generation magnetic field.In the middle of the drum is the concentrated area of the magnetic line of force, and thermistor just in time is in magnetic line of force close quarters.And magnetic field can be to METAL HEATING PROCESS, so the metal pins of thermistor is also inevitably understood self-heating, and temperature is reached thermistor.Obviously in this case, itself has been subjected to interference thermistor, and its numerical value is not the real embodiment of pan temperature.
The utility model content
The utility model purpose is that a kind of electromagnetic oven wire coil that can accurately measure the electromagnetic oven temperature is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of electromagnetic oven wire coil comprises thermistor mount, copper coil, plate rail, magnetic stripe; Described plate rail is roughly rounded; The center of described plate rail is provided with a hole; Described thermistor mount is arranged in the described hole; Described magnetic stripe is along on the lower surface that radially is located at plate rail of plate rail; Described copper coil is arranged on the upper surface of plate rail; The center of described copper coil is an emptying aperture.
Preferably, the diameter of the emptying aperture on the described copper coil is 1/3rd of a whole copper coil diameter.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
Electromagnetic oven wire coil of the present utility model, the copper cash inner ring stops around 2/3 place to whole disk track, and the drum inner ring diameter is strengthened.When drum was switched on, the magnetic field intensity in the middle of the drum reduced greatly because of the increase in space, and the magnetic interference that the thermistor that mediates is subjected to also reduces greatly, made thermistor can measure the temperature of top pan accurately.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1 is the three-dimensional exploded view of electromagnetic oven wire coil of the present utility model;
Wherein: 1, thermistor mount; 2, copper coil; 3, plate rail; 4, magnetic stripe.
Embodiment
Be illustrated in figure 1 as a kind of electromagnetic oven wire coil described in the utility model, comprise thermistor mount 1, copper coil 2, plate rail 3, magnetic stripe 4; Described plate rail 3 is roughly rounded; The center of described plate rail 3 is provided with a hole; Described thermistor mount 1 is arranged in the described hole; Described magnetic stripe 4 is along on the lower surface that radially is located at plate rail of plate rail 3; Described copper coil 2 is arranged on the upper surface of plate rail 3; The center of described copper coil 2 is emptying apertures; The diameter of the emptying aperture on the described copper coil is 1/3rd of a whole copper coil diameter; One thermistor (not shown) is arranged in the thermistor mount.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
Electromagnetic oven wire coil of the present utility model, the copper cash inner ring stops around 2/3 place to whole disk track, and the drum inner ring diameter is strengthened.When drum was switched on, the magnetic field intensity in the middle of the drum reduced greatly because of the increase in space, and the magnetic interference that the thermistor that mediates is subjected to also reduces greatly, made thermistor can measure the temperature of top pan accurately.
Below only be concrete exemplary applications of the present utility model, protection range of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
