Description
Technical field
The utility model relates to small household appliances technical field for kitchen use, particularly a kind of drum temperature measuring equipment and adopt the electromagnetism drum of this device.
Background technology
Because electromagnetic oven is in the course of the work the time, the temperature of electromagnetic wire panel surface is very high, occurs the electromagnetism drum possibly and damages even cause security incident because of overheated.In order to address the above problem, the applicant disclosed CN2859297Y patent " the temperature-sensitive thermometric structure of electromagnetic oven " on January 17th, 2007, and technical scheme is fixed on the electromagnetism drum lower surface for temperature sensor is close to.In the electromagnetic oven course of work; when the coil of electromagnetism drum occurs when overheated; temperature sensor passes to electric control system with the temperature signal of drum; electric control system quits work according to the signal controlling electromagnetic oven of temperature sensor or action such as early warning; thereby protection electromagnetism drum avoids the electromagnetism drum to damage or danger on fire because of overheated.
As shown in Figure 1 to Figure 3,, one temperature sensor 2 is installed, temperature sensor 2 is directly contacted with coil 3 lower surfaces, coil surface is directly carried out thermometric by resiliency supported at electromagnetism drum coil 3 lower surfaces for the thermometric structure of the electromagnetism drum of prior art.Existing coil 3 be by with multiply than the multiply bunch of fine enamelled wire by a stranded constant pitch, be wound in plane or spill multiturn disccoil then, every circle bunch cross section is circular, because round section is tangent, can form the gap of a class triangle between adjacent turn, the tension force during in addition owing to winding varies in size and also can cause the difference of gap length.Because the personal error of installing, can not guarantee the consistance of sensor installation site, following situation can appear in temperature sensor 2 and coil 3 contacts site: 1, temperature sensor 2 is between the stranded enameled wire of two circles, contact simultaneously with this two circles enameled wire, this moment, temperature sensor 2 temperature-sensitive areas were bigger, thermometric relatively accurately with in time, when temperature anomaly, can in time start overheating protection; 2, temperature sensor 2 is positioned at certain top, circle enameled wire circular section, contact with certain circle enameled wire, this moment, temperature sensor 2 temperature-sensitive areas were less relatively, there is hysteresis in the heat transfer of coil like this, the protection point of temperature sensor 2 is higher relatively, will cause drum overheating protection deviation bigger like this, guard delay; 3, there is certain deviation in temperature sensor 2 with the coil circumferencial direction, and temperature sensor 2 contacts respectively with the multiturn enameled wire, and the temperature value of overheating protection this moment is inconsistent with preceding two kinds of situations again.Therefore temperature sensor 2 measured temperature deviations are bigger in the existing dish thermometric structure of prior art; And because installation errors, different drum temperature protection value deviation drifts are bigger.
In addition; in the electromagnetism drum of prior art generally with epoxy resin with on the online disc carrier of coil stationary; and epoxy resin can be softening about 160 ℃; the coil jack-up of temperature sensor 2 above may be under the elastic reaction of resiliency supported with it; temperature sensor 2 is come out; under the effect of radiator fan; the sensing temperature value of temperature sensor can be more on the low side than reality; cause drum overheating protection hysteresis thus; temperature sensor 2 actual measured temperatures are lower than the drum actual temperature; roughly the real protection value is higher, the risk that exists protection to lose efficacy.Especially when repeatedly situation was moved in the drum overheating protection, this deviation can be aggravated, and has potential safety hazard.
Summary of the invention

A kind of drum temperature measuring equipment comprises coil, drum support, temperature sensor, and coil is installed on the drum support, and described drum temperature measuring equipment also comprises heat-conducting piece, and heat-conducting piece is arranged at coil surface, and temperature sensor is close to heat-conducting piece and is installed.
By the conduction of heat of heat-conducting piece, to have eliminated because the temperature measurement error that alignment error is brought makes temperature measurement accuracy more accurate, the drift of temperature protection value is little, can in time accomplish overheating protection.
Another purpose of the present utility model is to provide a kind of electromagnetism drum that adopts above-mentioned drum temperature measuring equipment, and in order to reach above-mentioned purpose, the utility model is reached by the following technical solutions:
A kind of electromagnetism drum comprises the drum temperature measuring equipment, and described drum temperature measuring equipment comprises coil, drum support, temperature sensor, coil is installed on the drum support, described drum temperature measuring equipment also comprises heat-conducting piece, and heat-conducting piece is arranged at coil surface, and temperature sensor is close to heat-conducting piece and is installed.
Owing to adopted the structure of the good heat-conducting piece of thermal conductivity; the temperature of coil can be directly conducted to temperature sensor; and enlarged the temperature-sensitive area of temperature sensor; it is inaccurate to have eliminated the thermometric that the error of installation site brings; the problem that the drift of temperature protection value deviation is big, thermometric is accurate, reliability is high.In addition owing to adopted heat-conducting piece, the elastic force of the resiliency supported of temperature sensor is disperseed, lifting surface area strengthens, and has avoided coil by the risk of resiliency supported jack-up, makes thermometric more accurate, and consistance is better.
