Abstract

A temperature sensing and warning sheet for cookers is provided, which is a part of a cooker and used to indicate temperatures in different colors. The sheet comprises a substrate, a temperature-sensing color-changeable body and a covering layer. The temperature-sensing color-changeable body is attached to the substrate. The covering layer is attached to the substrate and the temperature-sensing color-changeable body. The temperature-sensing color-changeable body can be heat-sensitive color-changeable powder or heat-sensitive color-changeable ink. The substrate is a metal sheet or a PVC film. The covering layer is a resin molded layer. The bottom of the substrate is adhered to the surface of the cooker by using an aversive. The utility model has the advantages of simple structure, easy production and installation, and no influence on the cooker's appearance; and is suitable for the use in various cookers.

Description

Cooking apparatus caution thermal sensitive piece

Technical field

The utility model belongs to cooker, particularly a kind of annex of using the different colours indicated temperature on the cooker that is installed in.

Background technology

The conventional kitchen utensil is through the cooking or furnace temperature are too high for a long time; its handle, carry ear, heat up in positions such as lid button etc.; especially the handle made of metal material, carry ear, lid button conduct heat faster, temperature is higher; owing to lack the temperature-sensitive alarm function; cooker can contact under unwitting situation usually, therefore has the potential safety hazard of scalding.Publication number is that the utility model patent of CN2409506Y discloses a kind of colour developing indication Thermometer for pot, the loam cake that it comprises base, is connected with pot cover and is injection-moulded in the brass inserts in the base and is connected with base, between base and loam cake, be provided with an index dial, card is divided in the indicating area in several different temperatures scopes, on each tool zone, indicate pointer and corresponding digital respectively, on each zone, all be printed with the variable color printing paint corresponding with this regional temperature scope.This invention is installed in good temperature indicating effect really on the pot, but its process structure dislikes complicated slightly, and cost is higher, is necessary to improve.

Summary of the invention

The purpose of this utility model provides a kind of cooking apparatus caution thermal sensitive piece, and it comprises substrate, heat discoloration body and overlayer; The heat discoloration body is attached to above the substrate, and overlayer is attached to substrate with above the heat discoloration body.

Heat discoloration body wherein is the heat-sensitive variable colour powder, also can be heat-sensitive colour-changing ink.

As further improvement of the utility model, substrate can be that sheet metal also can be the PVC diaphragm; Overlayer is the resin forming layer; The underrun adhesive-layer of substrate and the surface engagement of cooking apparatus.

The utility model is from the security standpoint of cooker, by at container, lid, the handle of traditional culinary cuisine utensil, carry cooking apparatus caution thermal sensitive piece be installed on ear, lid button or the Hu Zui, when these position temperature variation, when especially heating up, discoloration member on the cooking apparatus caution thermal sensitive piece becomes another kind of color from a kind of color, when temperature continues to raise, can become another kind of color more again, multistage temperature spot is warned to cooker to remind, thereby effectively prevent the generation of scald accident, improved the security in the gastronomical process greatly.

The utlity model has simple in structure, easy production, easy for installation, do not destroy advantages such as cooking apparatus moulding, suit on all cooking apparatus, to install and use.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the structural drawing of the utility model embodiment;

Fig. 2 is the outside drawing of embodiment;

Fig. 3 is that the utility model is installed in the outside drawing on the pan handgrip;

Fig. 4 is that the utility model is installed in pot and carries outside drawing on ear and the handgrip.

Embodiment

Referring to Fig. 1 and Fig. 2, cooking apparatus caution thermal sensitive piece comprises substrate 1, heat discoloration body 2 and overlayer 3.Substrate 1 is a sheet metal; Several thickeners of heat-sensitive variable colour powder difference furnishing that have different thermo-responsive scopes with the varnish handle, zones of different is made heat discoloration body 2 above being imprinted on substrate 1 respectively with the method for serigraphy again, heat discoloration body 2 can be designed to character or pattern, be coated on the heat discoloration body 2 that the heat-sensitive variable colour powder makes with thermoset resin then, thermoset resin is coated with and has also covered the place that be not printed on the heat-sensitive variable colour powder on the substrate 1 simultaneously, after being heating and curing, form the overlayer 3 of layer of transparent, overlayer 3 has the ability of waterproof and oilproof dirt, can protect the heat-sensitive variable colour powder; At last paste the lastblock double coated film as adhesive-layer in the bottom surface of substrate 1, substrate 1 just can make things convenient for by adhesive-layer and securely with the surface engagement of cooking apparatus.

Referring to Fig. 3, pan has metal pan body 4, is riveted on the outside of pot body 5 with metal handgrip 5.Cooking apparatus caution thermal sensitive piece 6 is made suitable size and is bonded on the handgrip 5, and makes and be printed on one of heat-sensitive variable colour powder and face up.After pot body 4 heated up, heat passed to cooking apparatus caution thermal sensitive piece 6 by handgrip 5, and the heat-sensitive variable colour powder on the cooking apparatus caution thermal sensitive piece 6 becomes another kind of color from a kind of color change under the normal temperature, the attention of reminds people.

The pan of Fig. 4 has pot body 4, handgrip 5 and Ti Er 7, is pasted with a slice cooking apparatus caution thermal sensitive piece 6 on handgrip 5 and Ti Er 7 respectively, and the temperature at these two positions is all warned.

In other embodiment, adopt PVC plastic sheeting or soft resin to make substrate 1, on the PVC film, stamp heat-sensitive colour-changing ink with method for printing screen, have flexible cooking apparatus caution thermal sensitive piece thereby make to make; As adopt PVC film and soft resin to make the caution thermal sensitive piece, and can be crooked, with various geometric configuratioies such as the handle of coincideing, carry ear etc.; The heat-sensitive variable colour body that also can print the multilayer different temperature points when handle is warmed up to this one deck of which layer temperature spot with regard to variable color, reaches multistage caution effect to substrate.
