Description

A kind of window with anti-fog effect
Technical field
The application relates to window field, particularly relates to a kind of window with anti-fog effect.
Background technology
Window is a kind of transparent window for being easy to observe inner case being arranged on equipment, cabinet, door, It is generally clear glass, in conjunction with required condition, can be the special substances such as implosion guard.
But, owing to the interior condition such as equipment, cabinet is complicated, when differing bigger inside and outside ambient humidity, temperature, its perspective Glass surface easily adsorbs little water droplet, causes the inconvenience of observation；Existing window is for the poor effect of antifog aspect.
Summary of the invention
It is desirable to provide a kind of window with anti-fog effect, to solve problem set forth above.
Embodiments of the invention provide a kind of window with anti-fog effect, comprises window frame and window Mouthful, described window frame is square, and described see-through window is double-layer perspective glass, and, at least one side combining glass is anti- Mist glass, is vacuum structure between described combining glass.
The technical scheme that embodiments of the invention provide can include following beneficial effect:
The window of present invention combining glass based on anti-fog effect, this antifog glass surface is provided with antifogging coating, and it is right The contact angle of water droplet is less than 1 degree, has preferable hydrophilic effect, it is possible to prevent glass surface from water smoke etc. occur, thus solve Problem set forth above.
Aspect and advantage that the application adds will part be given in the following description, and part will become from the following description Obtain substantially, or recognized by the practice of the application.It should be appreciated that above general description and details hereinafter only describe It is exemplary and explanatory, the application can not be limited.
Accompanying drawing explanation
The invention will be further described to utilize accompanying drawing, but the embodiment in accompanying drawing does not constitute any limit to the present invention System, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain according to the following drawings Other accompanying drawing.
Fig. 1 is the structural representation of window of the present invention.
Fig. 2 is the Making programme figure of antifogging coating of the present invention.
Detailed description of the invention
Here will illustrate exemplary embodiment in detail, its example represents in the accompanying drawings.Explained below relates to During accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawings represents same or analogous key element.Following exemplary embodiment Described in embodiment do not represent all embodiments consistent with the present invention.On the contrary, they are only with the most appended The example of the apparatus and method that some aspects that described in detail in claims, the present invention are consistent.
Transparent material has a wide range of applications in industrial and agricultural production and life, but, due to the impact of surrounding, special Not being the impact of humidity in environment, transparent material surface easily produces atomization, causes transparency to decline, to production and the life of people Live and bring inconvenience, even cause heavy losses.
Anti-fogging measure is mainly started with from the condition destroying fogging, and one is from thermodynamics, installs heater and makes base material Surface temperature is higher than steam dew point, or the little dewdrop that installation ultrasound wave dispersion makes steam produce volatilized within the extremely short time For steam, the measure being usually taken is the method heated with hair dryer or film metal silk, removes transparent material surface Water smoke；Two is from the performance changing material surface, changes chemical composition or the microstructure of substrate surface, such as at not shadow In the case of ringing the function of material own, construct one layer of hydrophilic or hydrophobic wear-resistant coating at material surface, when little water drop contact During to this coating, due to the hydrophilic of coating or hydrophobic effect, little water droplet can coating surface sprawl into thin layer moisture film or Person tumbles, thus inhibits the formation of coating surface water smoke.
But, in prior art, using hair dryer or tinsel heating, there is device complicated, original paper is many, cost Height, the problem such as fragile, therefore coating is the main method solving transparent material surface fogging.
