Abstract
The invention relates to the technical field of cookers, in particular to a cooker with cooker bottom temperature sensors. The cooker comprises a cooker body and a handle. The temperature sensors extend to the end of the handle along the side wall of the cooker body and are directly connected with a data collector. Compared with the prior art, the temperature sensor structure applicable to the bottom of the cooker is designed. Through up-down slight rotation of two multi-section shells, the temperature sensors can be matched with deformation caused by thermal expansion and cold contraction at the bottom of the cooker, multiple sets of thermal electrodes are prevented from being damaged, and the service life is prolonged. Due to the fact that the multiple sets of thermal electrodes are connected in parallel and the multiple sets of sensors are installed, the temperature measuring range is enlarged, and various cookers with different diameters can be used. The temperature sensors and the data collector are directly connected based on the thermocouple principle, and therefore temperature data are continuously transmitted in time. In addition, a heat transfer conductive piece is attached to an upper layer metal plate at the bottom of the cooker, so that detection data are more approximate to the actual temperature value inside the bottom of the cooker, and errors are reduced.

Detailed description of the invention
Now by reference to the accompanying drawings the present invention is described further.
See Fig. 1-3, the present invention is a kind of pan with cooking bottom temperature sensor, comprises pan body and handle, is provided with temperature sensor 2 in the bottom metal of pan body 1, and handle 3 is provided with data acquisition unit 4.Temperature sensor 2 extends to the end of handle 3 along the sidewall of pan body 1, and is directly connected with data acquisition unit 4, can continue the temperature data transferring out tested position in time, the demand of temperature when reaching the culinary art of relative fast monitored pan.
See Fig. 4, temperature sensor 2 comprises thermode 5, heat transfer guide card 7 and multisection type shell 6, and the end of probe of thermode 5 is provided with heat transfer guide card 7, and heat transfer guide card 7 adds the area by thermo-contact at tested position, plays the effect of stable data.Some groups of thermodes 5 are in parallel, and several heat transfer guide cards 7 are arranged on several multisection type shells 6 respectively, carry out multi-point temp detection to the bottom of pan body 1.The output of thermode 5 is connected with data acquisition unit 4.
Heat transfer guide card 7 is fitted with the upper strata metallic plate bottom pan body 1, make the contact the bottom of a pan internal metallic material of heat transfer guide card 7 maximum possible, be detected the temperature at position and the temperature of pot inner bottom part with close, thus ensure to detect data closer to pot inner bottom part true temperature value.
See Fig. 5, several multisection type shells 6 are from beginning to end one by one, rotate up and down and form the angle of 175 °-200 °, temperature sensor 2 can be slightly out of shape up and down between two adjacent multisection type shells 6.
See Fig. 8, when multisection type shell 6 upwards turns to extreme position, the angle between two adjacent multisection type shells 6 is 175 °, and when multisection type shell 6 is pivotally lowered into extreme position, the angle between two adjacent multisection type shells 6 is 200 °.
Before heating, see Fig. 6, between temperature sensor 2 and thermal source 8, there is indent gap; When heating; see Fig. 7; due to pan body 1 deformation of bottom; gap smaller between temperature sensor 2 and thermal source 8; can rotate up and down slightly between two multisection type shells 6; temperature sensor 2 slightly can be out of shape up and down, adapt to the bottom of a pan distortion caused owing to expanding with heat and contract with cold, thus protection thermode 5 be not impaired.
The head of multisection type shell 6 is provided with groove, and afterbody is provided with projection, and the projection of a multisection type shell 6 inserts in the groove of another multisection type shell 6.The quantity of adjustment multisection type shell 6 and the installation site of heat transfer guide card 7, to form different temperature sensors 2, go for the pan body 1 that base diameter is 120 millimeters-210 millimeters.And for the unlike material pan of same base diameter, thermode 5 can be selected to be arranged on the temperature sensing effect that diverse location reaches best.
Multisection type shell 6 is made up of ceramic material.Ceramic material has the feature of high insulation, high temperature resistant and high strength, coordinates multi-segment structure, can adapt to the slight deformation that the bottom of a pan produces after the heating better.
Insulation sleeve is provided with outside thermode 5.
In the whole loop that temperature sensor 2 and data acquisition unit 4 build, do not adopt compensating wire.Distance≤500 millimeter between the cold junction of thermode 5 and hot junction, and during normal culinary art the bottom temp of pan body 1 and hot junction the highest about 250 DEG C, data acquisition unit 4 i.e. cold junction maximum temperature about 40 DEG C, so when controlling the distance between cold junction and hot junction, even if do not adopt compensating wire, also little on the display impact after temperature acquisition.
Thermode 5 operating temperature is-20 DEG C ~ 700 DEG C, because the furnace surface temperature scope of electric stove is between room temperature to 600 DEG C, so the temperature sensor scope of temperature sensor 2 is relatively large; Again because frequently working long hours with pan, environmental factor change is various, therefore select the thermocouple principle that the life-span is long, thermal response speed is fast, mechanical strength is high, temperature range is wide, required precision is not high, and select the thermode 5 of correspondence and can-20 DEG C ~ 700 DEG C temperature ranges of long-term work.
The present invention can adopt many group thermodes 5 to detect the temperature data of the bottom of a pan diverse location, to detect the uniformity of cooking bottom temperature, thus provides culinary art reference temperature for putting into non-uniform temperature at the bottom of food pans during culinary art.If when there is open circuit in Long-Time Service, the parallel connection of many group thermodes 5 also can ensure that the temperature detecting function of pan continues normal work.Same pan also can be provided with one group or the some groups temperature sensor be formed in parallel 2, to increase temperature sampling point.
The present invention detects the inside cooking bottom temperature data of household pan, for closed-loop control cooking temp provides the foundation data, in conjunction with the controller of data analysis and control kitchen range, final arrival reasonable energy utilization, economize energy, controls cooking temp and reduces to destroy benefit materials in cooking process, reduces the generation of harmful substance, reduces to cook PM2.5 and PM10 produced.In addition, temperature sensor stability of the present invention is strong, is easy to manufacture produce, modular construction configurable go out the temperature sensor of plurality of specifications, be also easy to be transformed in batch production.
