Abstract

A frost-free refrigerator of the utility model belongs to the technical field of refrigeration facilities. The utility model includes a refrigerating chamber and a refrigerating chamber evaporator arranged at the inner side of the chamber of the refrigerating chamber; the external surface of the evaporator is coated with a hydrophobic material layer; the utility model also includes a cold storage chamber; when a cold storage chamber evaporator is arranged at the outside of the chamber, the surface area of the chamber corresponded to the cold storage chamber evaporator is coated with hydrophobic material; when the cold storage chamber evaporator is arranged in the chamber, the external surface of the cold storage chamber evaporator is coated with hydrophobic material. The utility model has no need of adding a special defrosting deicing device; while in use, the surface of the chamber has no frosting and freezing conditions; moreover, the energy is saved.

Description

Frost-free refrigerator

Technical field

The utility model 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.

The utility model content

The utility model purpose is to provide a kind of frost-free refrigerator.

For reaching above-mentioned purpose, the utility model adopts following technical scheme: frost-free refrigerator, comprise refrigerating chamber, and freezer evaporator is positioned at refrigerating chamber chamber the inside, and this evaporator external is coated with hydrophobic material layer.

Also comprise refrigerating chamber, refrigerator evaporator is positioned at the chamber outside, and refrigerator evaporator corresponding cavity chamber internal surface zone is coated with hydrophobic material.

Also comprise refrigerating chamber, refrigerator evaporator is positioned at the chamber the inside, and the refrigerator evaporator outer surface is coated with hydrophobic material.

In the utility model, frost-free refrigerator can only comprise refrigerating chamber, also can comprise refrigerating chamber and refrigerating chamber.Freezer evaporator is positioned at the refrigerating chamber the inside, applies hydrophobic material at the freezer evaporator outer surface.Refrigerator evaporator can be positioned at refrigerating chamber outside or the inside, when being positioned at the refrigerating chamber outside, can apply hydrophobic material in refrigerating chamber inner surface corresponding region.When refrigerator evaporator 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 to current refrigerator like that at top and icing all around.When having food in the refrigerating chamber, dewdrop freezes in food or packaging for foodstuff, and food takes out the back and takes out simultaneously naturally and remove.Thereby do not need special defrost or deicing to handle, easy to use, energy savings.In the utility model, 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.Hydrophobic material can select to meet the hydrophobic material of sanitary condition, as and the hydrophobic material of contact angle between the 130-180 degree of water, as fluororesin, based on the hydrophobic materials such as polypropylene of CNT.
