Description

Cooking appliance door and the cooking appliance that this class door is arranged that the borosilicate glass inner panel is arranged
Technical field
The present invention relates to a kind of cooking appliance door (Garger  tet ü r), on this, scribble the chromatograph of the resistant to elevated temperatures non-enamel pigment that contains organic or inorganic bond and the layer of reflected infrared ray with borosilicate glass inner panel.
The invention still further relates to a kind of cooking appliance with this class door.
Background technology
The family expenses cooking appliance is particularly hotted plate the chamber of hotting plate that stove has the band feeding port in accordance with regulations, and this feeding port can be closed by the door that form is arranged.The also known cooking appliance that has full glass door.Here a kind of typical home device is to have burner hearth as hotting plate the baking oven in chamber, this stove now very major part be provided with pyrolysis auto purification device, act on by this pyrolysis auto purification and will hot plate residue under the pyrolysis temperature that is higher than 500 ℃ and resolve into ash.
By the higher temperature in the chamber hotted plate at the family expenses cooking appliance, this cooking appliance door and the form that constitutes by the glass plate assembly usually thus or full glass door is also corresponding is heated.Under the temperature of the other extra-high-speed that this occurs during to pyrolysis in pyrolysis-baking oven also especially like this.Therefore because this temperature load is being used for cooking appliance, particularly have under the situation of the form of baking oven of pyrolysis spontaneous combustion device or full glass door, adopt high-quality glass as door-plate.For adopting the inner panel of close burner hearth, this preferably adds prestressed borosilicate glass.The feature of this glass is special heatproof.
Because touch the danger that the form outside plate has burn, for the temperature that makes form or the full glass door outside is low as far as possible, known on form, providing with heat, promptly infrared reflection is to the coating of hotting plate the chamber.At the form described in the US 4898147, its inner panel that is made of borosilicate glass is equipped with the laminated coating of infrared reflecting like this, with and layer of inert between outside plate and inner panel come together to reduce and conduct heat.Adopt this measure can realize being suitable for the what is called " unexpected winner " of pyrolysis baking oven, this unexpected winner is defined by limiting temperature by GIFAM DOC 266/01, promptly in hotting plate the chamber during for about 500 ℃ the touch face of door can be in 23 ℃ of room temperatures (under the glass situation＜70 ℃).
The known in addition printing that enamel colour is provided on the inner panel of borosilicate glass to show special writing (letter, word) and symbol, particularly is suitable for user's operation indication, for example various programs of hotting plate.This class printing can the borosilicate glass inner panel on the face of door inside, also can be on the face of hotting plate the chamber, as described in DE 10007923 C1.Also provide the corresponding borosilicate inner panel that is suitable for cooking appliance door among the DE10143925 A1 by the enamel colour printing.
Common enamel colour melts on baking the time is having the borosilicate inner panel of glass surface.Therefore stress can appear in the different heat expansion owing to glass plate and printed article on glass plate under high temperature load, and enamel colour, combined based on the printing-ink and the exchange interaction between the borosilicate glass (ion-exchange) of glass melt, if impact the face of printed article dorsad, this stress can make the impact strength of glass plate descend.Gu this advises the enamel colour printing is applied on the outside of being impacted towards the meeting of hotting plate the chamber of inner panel in above-mentioned DE 10007923 C1.Because enamel colour now is not contain heavy metal, is not lead-free especially, thus be printed on unlimited with hot plate the inner plate surface that the chamber directly contacts on to stand heavy metal under high temperature load, particularly lead and can " evaporate " to the danger of hotting plate the chamber.This enamel colour layer surface of also having coarse few aesthetic feeling in addition.
Because be not suitable for the enamel printing with following characteristics of borosilicate glass now:
1. do not contain heavy metal
2. smooth aesthetic feeling surface is arranged
3. the impact strength that when impacting on the face in this coating dorsad, keeps the borosilicate glass plate,
Contain organic (as silicon or fluoropolymer polymer) or inorganic (waterglass so developed; Sol-gel-adhesive) the non-enamel pigment of adhesive, this pigment is different with common enamel colour, and it does not bond with glass surface because of fusing.This non-pottery pigment is described in patent DE10313630 early to some extent, and its disclosed content is drawn this as a reference.
Recently have a kind of based on SiO 2With the pigment of carbon as colorant (Pigment), it is by SiO 2Institute seals, described in DE 19525658 C1.
With described non-enamel pigment colored printing borosilicate glass form scribble the inner panel of reflected infrared ray layer the time, attempt so far with coat of colo(u)r directly coat reflected infrared ray the layer on.This causes the unreliability of some technology because make for the pigment that directly adheres on the borosilicate glass to be developed adhere to usually the infrared reflecting formed by stannic oxide materials layer on be insecure.Aforesaid in addition coat of colo(u)r is not very scratch resistant.
Summary of the invention
The object of the present invention is to provide a kind of above shown in the cooking appliance door with borosilicate glass inner panel, plate coating contains the layer and the printed article of reflected infrared ray in it, this printed article is secure adhesion and mar-proof.
By the present invention at a kind of cooking appliance door of borosilicate glass inner panel of the coating with the pigment coated and reflected infrared ray that scribbles the resistant to elevated temperatures non-enamel pigment that contains organic or inorganic bond thereon or under the situation of relevant cooking appliance with such, purpose of the present invention can unexpectedly following realization, promptly directly on the one side of inner panel, be coated with coat of colo(u)r, and on this coat of colo(u)r, be coated with reflected infrared ray the layer.
By measure of the present invention, promptly the layer that just is coated with behind coating pigment with reflected infrared ray just very advantageously obtains a kind of colored printing that resistance is arranged on the borosilicate glass inner panel.Except that this pigment on glass substrate than the high-adhesiveness, this colored printing still is scratch resistant because the layer of reflected infrared ray is stone, and this colored printing is protected with regard to mechanical aspects thus.Because because the used pigment of this colored printing also can keep this impact strength when the face that prints dorsad is hit, so this printing also can realize on the face of hotting plate the chamber dorsad of inner panel, promptly can there be coating thus and hots plate interaction between the chamber.
Certainly this printing also can be the realizing on the face of hotting plate the chamber of inner panel, imperial its be this reflected infrared ray layer covered this colored printing, and the pigment composition that has reduced this colored printing at least escapes into and hots plate in the chamber.
Known by DE 10162220 A1, on the glass plate of cooking appliance, be coated with two layers of coatings, this coating is by first dark color, and particularly the heat-reflecting layer of the heat radiation layer of black and second white placed on it constitutes.During this second layer should melt down most of reflect radiation heat, in contrast, fall to reach heat on the glass plate by this first dark layer radiation well.
In this document, do not find coat of colo(u)r and of hint or the suggestion of its relevant sticking problem based on different problems to forming by non-enamel pigment.
The solution of the present invention characterizes in the dependent claims, is described providing in addition by accompanying drawing.
