Description

A kind of refrigerator

The utility model belongs to a kind of family expenses preservation by low temperature equipment that is used for chilled food.

Refrigerator in the market all is made up of chamber door, casing and refrigeration system, in use, open can occur behind the chamber door cold and hot to flow phenomenon.Highdensity cold air can flow out outside the case at once in the casing, and the air of the high heat of the outer high humidity of case can be along with pouring in, and the time of opening the door is long more, and high more sensible heat that enters of frequency and latent heat are just many more, and the refrigeration system load is increased.Frosting is simultaneously also obviously accelerated, and power consumption is increased, and this sum of the two is equivalent to 1/3rd of the total power consumption of refrigerator.And with the development of tall and bigization of refrigerator, the area of chamber door is also bigger, and is this cold and hot stronger to flow phenomenon, to energy-conservation very unfavorable.Prior art is used the design of the glass door of low-temperature display cabinet on the domestic refrigerator, allows people can see the article that case is indoor across chamber door, so that seek.But transparent doors cost height, intensity is low, and heat-proof quality is poor, makes power consumption not fall anti-liter, and food does not have the lucifuge packing more in the family, and the light that sees through from door can make the food preservation time shorten.

The purpose of this utility model provides a kind of refrigerator, and the cold air that it can reduce when opening the door runs off, and realizes purpose of energy saving.

Technology contents of the present utility model is such, and in the chamber door back of refrigerator, front portion, case chamber is provided with secondary door, and its secondary door main body uses transparent material, and after opening at chamber door, secondary door is in closed condition, blocks the outflow of cold air.

Lower limb is particularly gone up at the edge of this pair door, is provided with the convection current pore and the convection current pore has associated shutoff device.

Effect of the present utility model is such, because during the daily use refrigerator of people, can not pick and place article after opening chamber door at once, and the place that needs elder generation to seek required article or put article, the time of the action rope need of article often is longer than thereafter and deposits, put to this section period, and people only need to seek with eyes without any action during this period of time.Like this when this refrigerator uses, after opening chamber door, observe that time of examining across transparent secondary door usefulness, cold air will be indoor at case by transparent secondary door shield, cold and hot flow phenomenon is not taken place and do not have and since subsequently the time of the actual act process of depositing article that takes place shorter relatively, so total cold airflow vector is seldom, remarkable energy saving effect is arranged, and adapt with people's use habit.Again because on the secondary door closable convection current pore is arranged, when the article that need are deposited are not closed this convection current pore for a long time, just separate in this part shared space of rack on the chamber door, the actual refrigerating volume of case chamber diminishes, only be the volume of that part of case chamber sealed in the secondary door, saved energy consumption for cooling, when article are a lot, open the convection current pore, cold air can flow out through the convection current pore, refrigerator recovers original refrigerating volume, and article also can be realized energy-conservation purpose after a little while in the refrigerator like this, and this utility model has realized goal of the invention fully.

Fig. 1 is the utility model, a kind of three-dimensional view of refrigerator example one.

Fig. 2 is the utility model, a kind of front view of refrigerator example two.

Fig. 3 is the utility model, a kind of side sectional view of refrigerator example two.

Fig. 4 is a shutoff device cutaway view of the present utility model.

Fig. 1 is the three-dimensional view of this refrigerator example one, the higher monoblock transparent material of one fan secondary door (3) this pair door (3) working strength is housed in chamber door (2) back, front portion, case chamber (1), as organic glass or polycarbonate sheet as the door body, this pair door (3) links to each other with the inwall of case chamber (1) by the hinge of right hand edge, the anterior size of secondary door size and case chamber (1) inner chamber is complementary, the length and width of just secondary door (3) are all slightly less than the length and width size of inner chamber longitudinal section, case chamber (1), about 1.0～2.0mm.Pair (3) when chamber door (2) the inside when opening is closed condition like this, and most cold air are blocked in the secondary door (3).Because secondary door (3) is tiny with the slit of case chamber (1) inwall, the cold air that releases seldom, so very little to the temperature inside the box, humidity effect.Then square magnet (4) length of side 2cm is housed the edge on secondary door (a 3) left side, closes magnet or the ferrimagnet that Shi Keyu is contained in case chamber (1) corresponding site at secondary door (3) and pick up the effect that secondary door lock is ended mutually.

This refrigerator example two is that secondary door (3) four fans are housed in front portion, chamber door (2) rear cabinet chamber (1) shown in Fig. 2,3, for the raising sealing effectiveness that matches with the four secondary doors of fan (3), a box-shaped body (4) that is similar to doorframe is housed on the anterior wall in whole case chamber (1), this box-shaped body (4) can be when processing case chamber (1) inner bag and case chamber (1) inner bag make an one piece cast molding, also can be made into independent member and be loaded in the case chamber (1).This box-shaped body (4) is in glove plate (5) leading edge plane in the same plane with it, be divided into a plurality of rectangle frames, size and each self-corresponding rectangle frame of each secondary door (3) are complementary, each secondary door (3) is all made a master with transparent material and is stopped part, can install engineering plastics frame (7) on transparent material four limits additional for improving intensity, and install elastic sealing strip (6) additional at the marginal surface that secondary door (3) is gone up and rectangle frame is in contact with one another.The square magnet of a length of side 2cm is adorned at the left then edge of each secondary door (3), after closing, can inhale mutually at secondary door (3) with the ferrimagnet that is contained in the corresponding position of rectangle frame, play effect, and produce certain force sealing strip (6) is pressed on the rectangle frame, to improve sealing effectiveness secondary door (3) locking.Fan pair door (3) or only one fanning the edge of pair (3) topmost every, preferably go up lower limb and respectively open two long 10cm, the strip convection current pore (8) of wide 3cm also is equipped with area greater than two convection current pores (8) on convection current pore (8), the tabular thing of transparent rectangle (9) that two convection current pores (8) can be covered.This plate object (9) is connected on the secondary door (3), as Fig. 4 by two slideways (10).This plate object (9) moves in slideway (10) and convection current pore (8) is closed, and at this moment Quilt with air conditioning is locked in the interior space, case chamber (1) of secondary door (3), can not flow out, and volume diminishes.When the material-putting space on the needs use chamber doors (2), plate object (9) can be removed and will discharge orifice (8) be exposed, cold air can flow out in convection current pore (8) like this, and cold air just can flow in whole case chamber (1) like this.Recover original use volume.Obviously, the structure of this shutoff device is not only a kind of.Should select form simple in structure for use.
