Abstract

The utility model relates to a radiation resistant induction cooker wire carrier comprises magnetic bars distributed in a magnetic bar support in radial type, wherein a coil is arranged on the magnetic bars; the magnetic bars are in a T-shape, the N and the S poles of the bars are upward tilting and are close to the bottom of a pot; a wire carrier support is arranged under the magnetic bar support whose two ends are upward tilting to form a baffling wall to pack the magnetic bar support, the magnetic bars and the coil inside. The T-shaped magnetic bars can reduce magnetic resistance of the wire carrier and reduces the radiation of the wire carrier. The aluminum support is in a semi-containing state, baffles the dispersion of radiation and effectively shields radiation.

Description

A kind of radiation protection electromagentic furnace drum

Technical field

The utility model belongs to the electromagnetic oven field, relates in particular to a kind of radiation protection electromagentic furnace drum.

Background technology

Electromagnetic oven is as a kind of emerging kitchen small household appliances, and with its flames of anger, thermal efficiency advantages of higher is popularized very soon.In electromagnetic oven, drum is to be formed by multiply enamel covered wire (enamel insulated aluminium wire) coiling, is to produce resonance the critical elements of power output.Drum is the critical elements that produces magnetic field in the electromagnetic oven, and the design of drum directly influences the radiation of an electromagnetic oven.The magnetic stripe of drum is the center with the drum in the traditional design, and journey is radial to be embedded in the plastic rubber bracket.And utility model patent: " reducing the method and the anti-leakage electromagnetic over coiler of electromagnetic oven electromagnetic interference " (patent No.: 200610043240.5) and the anti-leak high efficient electromagnetic oven drum (patent No.: 200620161475.X) propose to change the method for magnetic stripe in, certain effect has been played in the radiation of electromagnetic oven, but its effect has reduced the radiation that drum produces just at the magnetic resistance that reduces the magnetic line of force.For preventing that drum from being very limited to extraradial effect.

Summary of the invention

The purpose of this utility model is exactly in order to solve the deficiency of prior art, a kind of radiation protection electromagentic furnace drum with T-shaped magnetic stripe and drum support is provided, earlier magnetic resistance on the drum is reduced with T-shaped magnetic stripe, reduce the generation of drum radiation, do radiation shield with the drum support again, thoroughly solve the radiation problem of electromagnetic oven.

The technical scheme that its technical problem that solves the utility model adopts is:

This radiation protection electromagentic furnace drum comprises the magnetic stripe that radially distributes in the magnetic stripe support, and magnetic stripe is provided with coil, and magnetic stripe is T-shaped, and its N utmost point and S utmost point two ends are upturned, more near the bottom of a pan; The below of magnetic stripe support is provided with the drum support, and these drum support two ends are upturned, and forms barricade, and magnetic stripe support, magnetic stripe, coil are wrapped in wherein.

The utility model beneficial effect mainly shows: the utility model T-shaped magnetic stripe can reduce magnetic resistance on the drum, reduces the generation of drum radiation; Aluminum frame is and partly comprises state, hinders radiation direction diffusion, effectively radiation-screening all around.

Description of reference numerals: special-shaped magnetic stripe 1, aluminum frame 2, drum coil 3, pan 4, porcelain plate 5, magnetic stripe support 6.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

This radiation protection electromagentic furnace drum comprises the magnetic stripe 1 that radially distributes in magnetic stripe support 6, and magnetic stripe 1 is provided with coil 3, and magnetic stripe 1 is T-shaped, and its N utmost point and S utmost point two ends are upturned, more near the bottom of a pan.The below of magnetic stripe support 6 is provided with drum support 2, and drum support 2 adopts aluminum to be made into.These drum support 2 two ends are upturned, and form barricade, and magnetic stripe support 6, magnetic stripe 1, coil 3 are wrapped in wherein.Among Fig. 1: the 4th, pan, the 5th, porcelain plate.

Magnetic stripe 1 top view is " fourth " font.If shown in the accompanying drawing 1, because the N utmost point and all perks of the S utmost point of magnetic stripe, more near the bottom of a pan.When having electric current to flow through in the coil, the N plate S plate by perk directly is added to the bottom of a pan.Reduced the magnetic resistance of the magnetic line of force.Improve drum efficient,, reduced the generation of radiation because magnetic energy is fully used.Reason is radial branch in magnetic stripe again, and the peripheral magnetic stripe top (flux path) of drum spacing is big, causes radiation between the crack easily meeting, thus magnetic stripe to be made " fourth " font, as accompanying drawing 2.Form the magnetic wall in coil periphery, play radiation and absorb the effect of reflection.Reduce radiation to influence all around.

Aluminum steel disc carrier 2 is and partly comprises state, and drum is wrapped in wherein (as shown in Figure 1), and aluminum steel disc carrier 2 edges are higher than the drum coil, forms a shield shell, and shielding drum coil is to around the electromagnetic oven, radiation effective isolation radiation interference to external world.(shielding principle list of references: Yankee person of outstanding talent's " electromagnetic compatibility principle and designing technique " People's Telecon Publishing House 2004).

Sum up: this patent mainly utilizes T-shaped magnetic stripe 1 to reduce the radiation generation of drum, with aluminum steel disc carrier 2 drum is comprised the formation shield shell again.After above two step process, radiation is reduced in certain scope.
