Abstract

The utility model discloses an induction cooker comprising a wire coil, wherein, a microcrystal board is arranged on the wire coil, the area of the microcrystal board corresponding to the wire coil is defined as a fast heating area, and the area corresponding to the periphery and the central area of the wire coil is defined as a slow heating area. The induction cooker adopts two temperature measuring devices, one temperature measuring device is positioned in the slow heating area, and the other temperature measuring device is positioned in the fast heating area; through analyzing and processing the data of two measuring points, the temperature of a water bottle or the temperature of water in the water bottle is measured indirectly via adopting the fuzzy technology principle, thereby indicating the induction cooker to operate correspondingly and effectively solving the difficult problems bothering the induction cooker such as the water boiling, the dry burning and the like; the use is reliable, a little cost of the induction cooker is increased, and the microcrystal board is not damaged at the same time; and the induction cooker is convenient to be cleaned and has a good market prospect.

Description

A kind of electromagnetic oven

Technical field

The utility model relates to a kind of electromagnetic oven.

Background technology

Because of electromagnetic oven belongs to product cheaply; the electromagnetic oven of each manufacturer production generally has only double temperature protection at present; promptly one is placed on the IGBT; preventing that IGBT is overheated burns out; another is placed on below the crystallite plate of drum top; the temperature of indirect detection pot; because of the crystallite plate that heated the temperature of having a surplus itself; when second Hu Shui heated, what thermistor reflected was the temperature of crystallite plate point, rather than the temperature in the bottom of a pan; so present electromagnetic oven ubiquity can not accurately be measured the temperature of water when boiled; after often causing water to be opened, and very big gap is arranged, two minutes at least downtime; tens minutes at most; even the longer time just shut down, also can take place water also do not have boiled, the phenomenon of shutting down just.In order to address this problem, also there are a lot of producers using technology such as wireless temperature measurement, vibration thermometric, multi-point temperature measurement.

Though wireless temperature measurement can directly be measured water level and water temperature, its cost increases, and the process complexity increase, causes the cost of product to increase, and because the defective of technology or technology, the reliability of this technology is not high.

The vibration thermometric is that bubble vibrates whether detect water boiled when utilizing water boiled, and its cost is low, but is subjected to environmental disturbances, and whether can not all detect water outlet constantly boiled, and accuracy is not high.

Multi-point temperature measurement is that two or more temperature elements are placed on below the crystallite plate; detect like this and put more at present below the crystallite plate of a temperature element above drum; its measurement accuracy is higher; but the temperature of institute's test point is not the real time temperature in the bottom of a pan, equally has the not corresponding to phenomenon of temperature with the bottom of a pan; still after can occurring that the water is boiling two, three minutes; even the longer time just shut down, perhaps produce water also do not have boiled, the phenomenon of shutdown just.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides the electromagnetic oven that a kind of cost is low, result of use is good.

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

A kind of electromagnetic oven, comprise drum, be placed with the crystallite plate on the drum, the described crystallite plate zone corresponding with drum is defined as generating heat and distinguishes soon, the zone corresponding with the periphery of drum and central area is defined as heating district slowly, and fast district of described heating and heating respectively are placed with a temperature measuring equipment in the district slowly.

As further improvement of the utility model, the temperature measuring equipment that described heating is distinguished slowly is placed on the central area and puts.

The beneficial effects of the utility model are: because electromagnetic oven does not require the actual temperature of accurately measuring kettle or water-in-kettle, the utility model adopts two temperature measuring equipments, a temperature measuring equipment is placed on heating and distinguishes slowly, another temperature measuring equipment is placed on the fast district of heating, compare analysis, handle through data two measurement points, adopt the fuzzy technology principle to measure the temperature of kettle or water-in-kettle indirectly, thereby the indication electromagnetic oven is made corresponding work.The utility model adopts multi-point temperature measurement technology relatively, has solved the difficult problem of puzzlement electromagnetic ovens such as boiling water, dry combustion method effectively, uses reliably, and the cost of electromagnetic oven increases few, also need not damage the crystallite plate, and cleaning is got up convenient, has good market prospects.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is that schematic diagram is divided in crystallite plate zone;

Fig. 2 is a structural representation of the present utility model

The specific embodiment

With reference to Fig. 1, Fig. 2, a kind of electromagnetic oven, comprise drum 1, be placed with crystallite plate 2 on the drum 1, described crystallite plate 2 and the drum 1 corresponding zone fast district Q that is defined as generating heat, the zone corresponding with the periphery of drum 1 and central area is defined as heating and distinguishes S slowly, Q is distinguished in described heating soon and heating is distinguished S slowly and respectively is placed with temperature measuring equipment M1, a M2, wherein, M2 distinguishes the temperature measuring equipment of S slowly for the temperature measuring equipment of the fast district of heating Q, M1 for heating.

As further improvement of the utility model, the temperature measuring equipment M1 that S is distinguished in described heating slowly is placed on the central area.

Electromagnetic oven is to produce magnetic field by drum, see through the crystallite plate, on pot or stove and accessory, produce eddy current and generate heat, thereby reach the article in pot or the stove and accessory are heated, and the characteristic of crystallite plate has vertical heat transfer, the temperature measuring equipment M2 of the fast district of heating Q distinguishes the temperature measuring equipment M1 quick heating of S slowly during heating than heating, and water is when boiled, the numerical value that the temperature measuring equipment M2 of the fast district of heating Q and the temperature measuring equipment M1 that distinguishes S slowly of generating heat record is identical, the utility model utilizes this characteristic of crystallite plate exactly, adopt multi-point temperature measurement technology relatively, compare analysis through data to two measurement points, handle, adopt the fuzzy technology principle to measure the temperature of kettle or water-in-kettle indirectly, thereby the indication electromagnetic oven is made corresponding work, solved boiling water effectively, the difficult problem of puzzlement such as dry combustion method electromagnetic oven, use reliably, the cost of electromagnetic oven increases few, also need not damage the crystallite plate, cleaning is got up convenient, has good market prospects.
