Description
Technical field
The present invention relates to intelligent dining table field more particularly to a kind of dining table closure of openings control systems.
Background technology
Dining table is divided by material：Solid wood and glass dining table.
1, wooden dining table, great advantage is the wood grain being like nature itself, with diverse natural colour.Due to natural wood
It is the organism constantly breathed, it is proposed that you are placed in the suitable environment of humiture, while must avoid beverage, chemical agent or mistake
The object of heat is placed on surface, in order to avoid the natural colored of damage wood surface.If melamine board material is built when dirt is more
It discusses you first to wipe once with warm water using the mild detergent assistant diluted, then is wiped with clear water, remembered with soft dry cloth
It wipes residual from water stain, after cleaning completely, reuses protective wax brighten, even if being crowned with success, have only and pay attention to daily cleaning
With maintenance, can just wooden furniture be made to sustain its quality through age.
2, glass has fragility, therefore glass furniture is preferably both placed in relatively fixed place, does not often move back
It is dynamic.The article being placed on furniture is paid special attention to handle with care, is otherwise easy to damage glass surface.The higher glass dining table of utilization rate
Or avoid firmly colliding as possible when tea table, the tablecloth can be spread above, prevent glass surface from being scratched.Usually clean glass man in family
When tool, for general spot, we are wiped with wet towel or newspaper, toilet paper.If there is more difficult clean dirt above
Stain can dip in the light-coloured vinegar erasing of some white wine, beer or warm with towel, must not use the stronger cleaning liquid of acid-base property, because
Main component for glass is silica, not strong alkali-acid resistance, this substance easily corrodes glass.Wipe the hair glass of patterned
When glass, some detergents can be dipped with toothbrush, and spot can be removed along the pattern wiping that loop.This kind of glass also can be upper
A few drop kerosene or chalk dust are dripped in face and land plaster dips in water and is coated on glass, are wiped with clean cloth or cotton after drying, in this way
It is not only clean but also bright to clash the glass come.
