Abstract
The utility model provides an induction cooker coil disk, which belongs to the technical field of electromagnetic heating for the kitchen. Comprising an electromagnetic coil, a wire coil bracket and magnetic strips which are arranged in the wire coil bracket in scattered state, the utility model is characterized in that the center part of the coil bracket is opened with a plurality of air guide holes. Solving the shortcomings of burning machine by high temperature and high cost of the prior induction cooker coil disk, the utility model provides an induction cooker coil disk which has advantages of perfect radiation effect, low production cost and favorable assembled magnetic effect as well as prolonging the effective working time of the electronic element of the induction cooker and improving the utilization rate of the magnetic field energy.
Description
Technical field
The utility model belongs to electromagnetic heating technique for kitchen use field, is specifically related to the coil panel structure that electromagnetic oven is used.
Background technology
Electromagnetic oven becomes the kitchen appliance that is widely used at present, the core key components is a coil panel in the electromagnetic oven, coil panel caloric value when work is big, if can not be under a certain temperature spot the coil panel surface temperature control, cause that easily coil panel copper cash burning is black, insulating barrier burns out, influence the service life of coil panel, even the fire incident of complete machine may take place.Therefore strict control coil panel surface temperature becomes and makes one of difficulty that electromagnetic oven must capture.
Electromagnetic oven heat coil dish is made up of magnetic stripe, coil and drum support, cover coil on the magnetic stripe, though the magnetic field major part that produces all is distributed in the scope of work, but Distribution of Magnetic Field that fraction disperses is arranged outside the scope of work at the edge of coil panel, the energy in this part magnetic field is not utilized, cause the waste of the energy, also reduced the thermal efficiency of electromagnetic oven.
China utility model patent CN2702572Y (open day is on May 25th, 2005) " a kind of coil disc of electric stove " for improving the thermal efficiency, economize on electricity, is provided with the magnetism gathering rings that magnetic material is made around coil.Because magnetism gathering rings influences the Distribution of Magnetic Field that original coil panel produces, strengthened magnetic field with the coil panel effect, reach the high effect of the thermal efficiency, but there is following shortcoming in electromagnetic oven structure in the above-mentioned prior art, the one, ventilation effect is bad, and stake body central authorities are burnishing surface, and coil twines on the central boss, core does not have air-vent, high hot polymerization collection; The 2nd, the magnetism gathering rings of annular makes expensive magnetic material consumption big.
Summary of the invention
The utility model is in the environment of high temperature for a long time at the coil disc of electric stove of prior art golf calorific value, reduced the effective time and be prone to defective that high temperature burns and expensive deficiency, provide a kind of radiating effect obviously, low cost of manufacture, work safety, reliable and stable coil disc of electric stove.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of coil disc of electric stove comprises solenoid, drum support and magnetic stripe, and magnetic stripe is radial and is installed in the drum support, and described drum carriage center partly has a plurality of air-guiding holes.
As further improvement, disc carrier periphery along the line has a plurality of grooves that hold magnetic stripe.Groove promptly can embed magnetic stripe and reach poly-magnetic effect, and under the situation that does not influence support intensity, reduces the materials of support, saves cost.
Preferably, described groove is 8, and annular spread is in the periphery of drum support.
Inventive concept of the present utility model is: by increase several air-guiding holes on support, do not influence support intensity, the wind flow on coil panel surface is strengthened, thereby reduce the coil panel surface temperature; The groove of drum bracket edge is embedded in magnetic stripe, and magnetic field energy is concentrated in the working range of electromagnetic oven more, the experiment proved that, the poly-magnetosphere of the energy utilization ratio and the thermal efficiency and domain shape is very nearly the same, reaches the effect of power and energy saving equally.
Coil disc of electric stove of the present utility model compared to existing technology, beneficial effect is embodied in: good heat dissipation effect, effective time of electromagnetic oven electronic devices and components increases, production cost reduces and poly-magnetic is effective, has increased the utilization rate of magnetic field energy.
Figure of description
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Coil disc of electric stove of the present utility model shown in Figure 1 comprises drum support 1, solenoid 6 and magnetic stripe 5, and magnetic stripe coil 6 is covered on the magnetic stripe 5, and magnetic stripe 5 is radial and is installed in the drum support 1.
Drum support 1 core have several air-guiding holes 3, air-guiding hole 3 is one section arc, is surrounded on around the centre bore of drum support, the section of air-guiding hole 3 can be other geometries such as parallelogram, circle.The number of air-guiding hole 3 from one to dozens of, can be decided according to actual conditions.Air-guiding hole 3 distributes hub of a spool heat partly when not influencing the drum support intensity, effectively prolongs the working life of electromagnetic oven.
The periphery of online disc carrier 1 has a plurality of grooves 2, and groove can embed magnetic stripe 4 for 2 li, and the cross section of magnetic stripe 4 can be different geometric forms such as circle, ellipse, polygon.The groove number of groove 2 from one to the dozens of bar, can be decided according to actual conditions, and the number of magnetic stripe 4 is less than or equal to the groove number of groove 2, and present embodiment is 8 grooves 2 and 8 magnetic stripes 4, and annular spread is in the periphery of drum support.
Claims (3)
