Abstract
The utility model relates to a double-electromagnetic short-circuit ring type electromagnetic oven, which comprises an electromagnetic oven main body, a heating disk and a cooker support porcelain plate. The utility model is characterized in that the outside of a coil of the heating disk is provided with a main electromagnetic short-circuit ring; the outside of the cooker support porcelain plate is provided with an auxiliary electromagnetic short-circuit ring. The utility model has simple and reasonable structure, and the main electromagnetic short-circuit ring has the action of strongly absorbing four sides of horizontal electromagnetic radiation of the heating disk; the horizontal auxiliary electromagnetic short-circuit ring can enhance the action of the main electromagnetic short-circuit ring, and has the action of absorbing horizontal upper side electromagnetic radiation of the heating disk. The double electromagnetic short-circuit rings can particularly attenuate the strong electromagnetic radiation caused by a small cooker (about 8CM) heating to a reasonable level. The normal work of an electromagnetic oven can not be influenced. The double-electromagnetic short-circuit ring type electromagnetic oven has very large help to an EMC test.
Description
Technical field
The utility model relates to a kind of electromagnetic oven, particularly a kind of pair of electromagnetism short-circuited conducting sleeve electromagnetic oven.
Background technology
Existing electromagnetic oven can produce harmful electromagnetic radiation to peripheral electrical equipment, equipment, personnel when heating plate is worked, the harm people's is healthy.
The utility model content
It is a kind of simple and reasonable that the purpose of this utility model is to provide, and can absorb the electromagnetic radiation of heating plate level four sides and upside, and it is attenuated to two electromagnetism short-circuited conducting sleeve electromagnetic ovens of reasonable level.
The purpose of this utility model can reach by following measure: a kind of pair of electromagnetism short-circuited conducting sleeve electromagnetic oven, comprise electromagnetic oven main body, heating plate, hold a pot porcelain plate, it is characterized in that: the coil at heating plate is outside equipped with main electromagnetism short-circuited conducting sleeve, is provided with secondary electromagnetism short-circuited conducting sleeve outside pot porcelain plate holding.
The purpose of this utility model can also reach by following measure: the distance of main electromagnetism short-circuited conducting sleeve and heating plate coil outer ring is 1～4 centimetre.Lead or bonding jumper that main electromagnetism short-circuited conducting sleeve is closed by a trap are made.The diameter of secondary electromagnetism short-circuited conducting sleeve is bigger 2～10 centimetres than the diameter of the coil of heating plate.The becket that secondary electromagnetism short-circuited conducting sleeve is closed by a trap is made, and be convex-edge shape, and holds a pot porcelain plate composition tray shape.
The utility model has following advantage compared to existing technology: simple and reasonable, main electromagnetism short-circuited conducting sleeve has the effect of powerful absorption heating plate level four side electromagnetic radiations, secondary electromagnetism short-circuited conducting sleeve can be strengthened the effect of main electromagnetism short-circuited conducting sleeve, and has the effect that absorbs the horizontal upside electromagnetic radiation of heating plate; Especially pannikin (about 8 centimetres) is heated the strong electromagnetic radiation that causes, two electromagnetism short-circuited conducting sleeves can be attenuated to reasonable levels to it, and to electromagnetic oven operate as normal did not influence, but test is very helpful to EMC.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the rigging position schematic diagram of main electromagnetism short-circuited conducting sleeve and heating plate coil.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to Fig. 1, Fig. 2, the utility model comprises electromagnetic oven main body 1, heating plate 2, holds pot porcelain plate 3, main electromagnetism short-circuited conducting sleeve 4, secondary electromagnetism short-circuited conducting sleeve 5 etc.At electromagnetic oven heating dish 2 in-planes,, be placed with main electromagnetism short-circuited conducting sleeve 4 apart from heating plate coil outer ring 1～4 centimeters; Lead or bonding jumper that main electromagnetism short-circuited conducting sleeve 4 is closed by a trap are made.Hold holding on pot porcelain plate 3 of pot face at electromagnetic oven, place a loop diameter secondary electromagnetism short-circuited conducting sleeve 5 bigger 2～10 centimetres than heating plate coil diameter; The becket that secondary electromagnetism short-circuited conducting sleeve 5 is closed by a trap is made, and be convex-edge shape, and holds pot porcelain plate 3 composition tray shapes, plays the anti-skidding effect of pan.Cooperatively interact by major and minor pair of electromagnetism short-circuited conducting sleeve, solve electromagnetic oven and suppress influence peripheral electrical equipment, equipment, personnel in cauldron, pannikin EMI electromagnetic interference.As long as two electromagnetism short-circuited conducting sleeve designs are proper, to electromagnetic oven operate as normal did not influence.
