Abstract

The utility model is applicable to all refrigerator doors, the usage of the refrigerator door especially can reduce the times for opening the refrigerator door and the air flow when articles are accessed. When using a rack, the articles on the rack can be accessed only by undrawing the rack, therefore, the convection between the cold air in the refrigerator door and the outside hot air can be effectively prevented, thus achieving the goal of energy saving. In the device, a plurality of movable racks are arranged outside the refrigerator door; the two sides of the movable rack are provided with return springs which are connected with the refrigerator door; the movable racks are connected with the refrigerator door by movable bearings; part of the movable rack (2) on the refrigerator door (1) penetrates deeply in the refrigerator door, and the other part of the movable rack is arranged outside the refrigerator door and connected with a pull handle, therefore, the movable rack can be directly opened outside the refrigerator door to avoid opening the refrigerator door when only needing to take one egg, thus reducing the air flow, reducing the heat change and achieving the goal of energy saving, meanwhile, the energy-saving refrigerator door brings convenience for people to access articles on the rack.

Description

The refrigerator energy-saving chamber door

Technical field

The utility model relates to the device that a kind of refrigerator energy-saving is deposited the thing frame, and the air in the time of especially reducing the number of times of opening chamber door and accessing article flows.

Technical background

What present refrigerator generally adopted is directly to get article in refrigerator, at this moment, whole door of refrigerator mouth all opens wide, cold air in the refrigerator and the extraneous rapid convection current of hot-air, the very fast rising of temperature in the refrigerator, for Keep cool temperature, refrigeration system has to increase the working time, Sun Shi energy can reach 40% of the whole power consumption of refrigerator therefrom.This phenomenon is especially outstanding summer, because opening the door each time can cause all that violent air flows and cause a large amount of cold airs to flow out outside the case, hot-air enter in the case and consumption in vain a large amount of electric energy, too frequent if open the door, on the one hand the power consumption of refrigerator is obviously increased, the service life that also can reduce refrigerator simultaneously.Because the chamber door of refrigerator is bigger, if door opening times is more, the cold air in the case escapes, and the outer warm-humid air of case avails oneself of the opportunity to get in, and the temperature inside the box is risen.The humid air that advances simultaneously in people's case makes the evaporator surface frosting accelerate easily, and the frosting layer thickens.Because the thermal conductivity factor of the thermal conductivity ratio evaporator material of frost is much smaller, be unfavorable for the heat conduction, cause the temperature inside the box to descend slowly, the compressor operating time increases, and wearing and tearing are accelerated, and power consumption increases.If evaporator surface frosting layer thickness is during greater than 10 millimeters, then heat transfer efficiency will descend more than 30%, cause refrigerating efficiency significantly to reduce.In addition, when opening chamber door, case intraoral illumination lamp is just opened, and not only consumed power but also distribute heat obviously also are unfavorable for energy-conservation.If to open the door half a minute to 1 time minute at every turn, temperature restores to the original state in the refrigerator, compressor will be worked 5 minutes, power consumption 0.008 kilowatt hour, along with the raising of people's living standard, refrigerator just develops towards jumbo direction, and refrigerator all exists such problem just more and more obvious now.

Summary of the invention

All to open the shortcoming of chamber door when any article of access in order to overcome present current refrigerator, the utility model can be deposited in use need not open door of refrigerator in the thing frame process and directly from depositing accessing article on the thing frame, so just can avoid getting an egg or one bottle of beverage on the thing frame and need opening door of refrigerator depositing, thereby the air that reduces door opening times and reduce when accessing article flows, thereby reduces the consumption of electric energy.

The technical scheme that its technical problem that solves the utility model adopts is: will adopt some activities are installed outside chamber door deposit the thing frame for a short time, when the thing frame is deposited in use, need only draw back and deposit the thing frame, can access deposit the article on the thing frame, avoid under the situation of getting an egg, also will opening chamber door and can be directly deposit the thing frame in the refrigerator outside activity of opening, thereby from the depositing access thing the thing frame and can effectively prevent cold air and extraneous hot-air convection in the chamber door of activity, to energy-conservation effect.

The beneficial effects of the utility model are need not open chamber door when depositing thing frame article taking, thereby the air when avoiding opening the door flows, and prevents that hot-air from entering the minimizing energy consumption.
