Abstract

The utility model discloses an induction cooker panel. A plurality of protuberances to support a pan-body is arranged on the panel, then the touching area between the panel and the pan bottom is smaller and the ventilation between the pan body and the majority part of the panel can be kept. Because the touching area is small, the transferred heat energy is low, and adding the ventilation on the panel and the upward heat energy of the pan, the temperature of the whole panel can not rise so high. Thus the problem of that the panel temperature rises too high can be solved. In addition, with the existence of ventilation the water on the pan-bottom will not have impact on the panel as the water can flow away or be dried. As regards to the temperature-sensing, the temperature sensing part on the panel can also be touched with the pan bottom with no difference with the prior state.

Description

Electromagnetic oven panel

Technical field

The utility model relates to a kind of electromagnetic oven, refers to the panel construction of electromagnetic oven especially.

Background technology

Present electromagnetic oven panel all is a face contact type, so-called face contact type, be meant the electromagnetic oven of present production, no matter be complete plane or be with pot body spacing collar outward, their electromagnetic oven panel all is directly contact of large tracts of land with contacting of pot body, when promptly heating, their contact-making surface is very big.Yet electromagnetic oven is different fully with electric frying pan in the past, and its advance is not conducted heat with contacting of pot by stove with regard to being.The heating that is electromagnetic oven is not conducted heat by panel, but the high-frequency alternating magnetic field that produces in the machine passes panel, produces eddy current and then be converted into (the Q=0.24I of heat in pot body metal ²Rt).On the contrary, panel has been the three big functions that support the bottom of a pan, double as shell, subsidiary temperature-sensitive.Though existing panel is all very beautiful,, also there is certain problem with regard to its function.One, as " shell " function, it directly contacts with the bottom of a pan of high temperature in large area is very bad, can cause panel temperature too high, except overheated may hurting sb.'s feelings, also have following point: the one, the plastic housing around the panel is yielding, tear, and then the electric leakage of leaking, and this is ubiquitous phenomenon; The 2nd, component temperature raises in the machine, shortens the service life of electromagnetic oven; The 3rd, the temperature tolerance of counter plate and shell is had higher requirement; The 4th, wasted some heat energy.Its two, as " support " function, when reaching boiling point, the hot water in the bottom of a pan is sprayed when there is water (washed and do not dry, or the boiling of the soup in the pot time is overflowed) in the bottom of a pan everywhere, and pot body is drifted about because of being heated, dangerous situation appears.Its three, as " temperature-sensitive " function, temperature detector detects temperature of boiler across panel, thereby wishes that the heat-transfer capability of panel is strong more good more, but as shell, wishes that again the panel heat-transfer effect is poor more good more, this has become a pair of insurmountable contradiction.

The utility model content

The purpose of this utility model is to provide a kind of and the less electromagnetic oven panel of the bottom of a pan contact-making surface.

For reaching above-mentioned purpose, technical solution of the present utility model is: a kind of electromagnetic oven panel wherein is provided with some projections that support the pot body on panel.

Described projection is point-like or strip.

Described projection is the combination of point-like and strip.

Described projection is an obform body.

Be provided with the temperature-sensitive point in described panel central authorities.

After adopting such scheme, because the utility model is provided with several projections on electromagnetic oven panel, it makes electromagnetic oven panel and the bottom of a pan contact area less, be so-called some contact, that is to say that panel is not a plane completely, it is made up of the pot body strong point of plane and projection, this strong point can be circle dot mode, line type or various moulding formula ..., in a word, it contacts the sub-fraction that only accounts for whole front panel with pot, and most of panel is keeping circulation of air with a pot body.Because contact area is little, transferring heat energy is just few, and adding has circulation of air on the top panel, and the heat energy of pot makes progress again, and the temperature of whole front panel just can not rise so highly naturally.The too high caused problem of panel temperature rise has solved.In addition, because circulation of air is arranged, the bottom of a pan has water also not to be afraid of, and water can flow away or be dried.As for temperature-sensitive, the panel at temperature-sensitive place can contact with the bottom of a pan equally, is as good as with existing situation.

The specific embodiment

As shown in Figure 1, electromagnetic oven panel 1 described in the utility model is provided with some prominent points 11 in its surface, and 1 central authorities are provided with temperature-sensitive point 12 at panel.When pot was placed on the electromagnetic oven, the bottom of a pan contacted with temperature-sensitive point 12 with prominent 11, rather than contacts with whole front panel.Panel 1 is less with the bottom of a pan contact area like this, and most of panel 1 is keeping circulation of air with the pot body, because contact area is little, transferring heat energy is just few, add circulation of air is arranged on the top panel, the heat energy of pot makes progress again, and the temperature of whole front panel just can not rise so highly naturally, and the too high caused problem of panel temperature rise has also just solved.In addition, because circulation of air is arranged, the bottom of a pan has water also not to be afraid of, and water can flow away or be dried.As for temperature-sensitive, the panel at temperature-sensitive place can contact with the bottom of a pan equally, is as good as with existing situation.

In addition, prominent point 11 of the present utility model can be evenly distributed on the panel 1, also can be by certain pattern distribution (as shown in Figure 2).

The utility model is except that adopting prominent also available strip projection 11 ' (shown in Fig. 3,4,5), or the obform body of other moulding, and its arrangement mode is not limit, and can make up according to the pattern needs, in a word yet, only need the pot body is propped, can reach the purpose of this utility model.
