Abstract
A frost-free refrigerator belongs to refrigeration facilities technical field. It comprises a refrigerating chamber or/and a freezing chamber, a refrigerating chamber evaporator or/and a freezing chamber evaporator being situated outside or inside the chamber.
Description
Technical field
The invention belongs to technical field of refrigeration equipment, particularly a kind of frost-free refrigerator.
Background technology
Refrigerator generally comprises refrigerating chamber and refrigerating chamber, and the simplest refrigerator comprises a refrigerating chamber and a refrigerating chamber.Recent years, based on the needs of food fresh keeping, the trend of the oriented multi-chamber of refrigerator development as cold compartment of refrigerator being subdivided into 7 ℃, 3 ℃, 0 ℃ three temperature spaces, is subdivided into refrigerating chamber in-18 ℃ ,-7 ℃ two greenhouses.No matter be several greenhouse refrigerators, its position, refrigerator evaporator place all wants frosting, refrigerating chamber all will freeze, and often need carry out defrost ice to refrigerator in the use and handle.Current refrigerator need consume big energy when defrost ice, if handle badly, can cause defrost not thorough, forms very berg after using a period of time, causes very big energy waste, and influences refrigerator and normally use.
Summary of the invention
The object of the invention is to provide a kind of frost-free refrigerator.
For reaching above-mentioned purpose, the present invention adopts following technical scheme: a kind of frost-free refrigerator, comprise refrigerating chamber or/and refrigerating chamber, refrigerator evaporator is or/and freezer evaporator is positioned at chamber outside or the inside, when evaporimeter was positioned at the chamber outside, evaporimeter corresponding cavity chamber internal surface zone or whole chamber inner surface were coated with hydrophobic material layer; When evaporimeter was positioned at the chamber the inside, evaporator surface was coated with hydrophobic material layer.
Comprise refrigerating chamber and refrigerating chamber, refrigerator evaporator, freezer evaporator all are positioned at the chamber outside, and refrigerator evaporator corresponding cavity chamber internal surface zone is coated with hydrophobic material, and the refrigerating chamber inner surface is coated with hydrophobic material.
Comprise refrigerating chamber and refrigerating chamber, refrigerator evaporator is positioned at the chamber outside, and freezer evaporator is positioned at the chamber the inside, and refrigerator evaporator corresponding cavity chamber internal surface zone is coated with hydrophobic material, and the freezer evaporator outer surface is coated with hydrophobic material.
Comprise refrigerating chamber and refrigerating chamber, refrigerator evaporator is positioned at the chamber the inside, and freezer evaporator is positioned at the chamber outside, and the refrigerator evaporator outer surface is coated with hydrophobic material, and the refrigerating chamber chamber inner surface is coated with hydrophobic material.
Comprise refrigerating chamber and refrigerating chamber, refrigerator evaporator, freezer evaporator all are positioned at the chamber the inside, and refrigerator evaporator and freezer evaporator outer surface are coated with hydrophobic material.
The contact angle of described hydrophobic material and water is between the 130-180 degree.
Described hydrophobic material is selected from fluororesin, based on the polyacrylonitrile of CNT, based on the polypropylene of CNT.
Among the present invention, frost-free refrigerator can only be established refrigerating chamber or refrigerating chamber, also refrigerating chamber and refrigerating chamber can be set simultaneously.Evaporimeter can be positioned at refrigerating chamber or refrigerating chamber chamber the inside or outside.When evaporimeter is positioned at refrigerating chamber or refrigerating chamber chamber outside,, can apply hydrophobic material in the corresponding refrigerating chamber inner surface area of evaporimeter for refrigerating chamber; For refrigerating chamber, can apply hydrophobic material at the refrigerating chamber inner surface.For the drawer type refrigerating chamber, can apply hydrophobic material at refrigerating chamber chamber interior upper surface and drawer inner surface.When evaporimeter is positioned at chamber interior, can apply hydrophobic material in evaporator external.In the refrigerator use, because the sticking water of hydrophobic material, the droplet that the refrigerating chamber chamber inner surface forms in time drops in the drip tray, and its surface can frosting; Refrigerating chamber inner surface top and dewdrop all around can drop to the bottom very soon, and can be at top and icing all around as current refrigerator.When having food in the refrigerating chamber, dewdrop freezes in food or packaging for foodstuff, and the ice nature took out simultaneously and removes after food took out.Thereby do not need to be provided with special defrost or deicer, do not need special disposal, easy to use, energy savings.Among the present invention, the evaporimeter that is installed in refrigerating chamber or the refrigerating chamber can adopt finned tube (fiber tube) formula evaporimeter, tube-in-sheet evaporator etc. to well known to a person skilled in the art evaporimeter.Used hydrophobic material can be any hydrophobic material that meets sanitary standard, and the contact angle of hydrophobic material and water can be selected fluororesin based on CNT for use, based on the hydrophobic materials such as polypropylene of CNT between the 130-180 degree.
