Abstract

The utility model relates to an automatic shutter for refrigerator belonging to the household electrical appliance field. The automatic shutter is adopted for solving the problem that the cooling air is discharged to cause a high energy consumption while opening the door of the refrigerator. The utility model comprises an upper and lower scroll which is provided with a spring rewind device, and a transparent soft curtain; the middle of the curtain is provided with an opening as fetching window; the transparent soft curtain is covered at the outside of the refrigerating chamber of the refrigerator. The window for fetching in the curtain is rolled into the scroll because of the rewind spring on the scroll; when in fetching, the fetching window is revealed by pulling down the curtain; after finishing fetching, the fetching window is rolled into the scroll again so that the refrigerating chamber of the refrigerator is in a sealing state, thereby the purpose of energy saving is reached. The utility model is applicable for the energy saving of various refrigerators.

Description

Refrigerator is rolled up Curtain automatically

The utility model belongs to field of household appliances.

At present, the defective that refrigerator exists aspect energy-conservation is after refrigerator doors is drawn back, and the cold air in the refrigerator all runs off because of the gravity effect of self, causes the increase of energy consumption of refrigerator.For addressing this problem, utility model patent CN85202706U and CN87204372U, 89215416.0 propose to install additional the method for inside door in refrigerating chamber; Utility model patent 88201850 and 89218988.6 proposes in refrigerating chamber every layer and installs north material film door curtain additional.Above-mentioned all methods all can stop the loss of cold air effectively, reach energy-conservation purpose, but still exist structure complicated, use inconvenient shortcoming.

The purpose of this utility model is to propose an easy more solution, to overcome the above-mentioned problem that exists.

The technical solution of the utility model is:

One monoblock type transparent flexible door curtain is housed in the refrigerator cold-storage outside, an opening is arranged in the middle of the door curtain as getting the thing window.

Door curtain is supported by two spools that are fixed in the refrigerating chamber upper and lower side, and refrigerating chamber is covered fully.

One end of two spools respectively is equipped with a wind spring, can carry out auto reeling to door curtain.

Spool wherein one the position and lock releasing device also is housed, when getting of door curtain automatically locked when the thing window is pulled to the position of hope, the accumulation of energy effect of door curtain mat spring is by automatic coiling (or last volume) during release, door curtain get that the thing window is involved in the spool and the closed state that recovers refrigerating chamber.

Compare with preceding method, the utlity model has simple in structure, good integrity, be easy to the assembling, advantage easy to use, with low cost.

Accompanying drawing 1 is a front view of the present utility model.

An embodiment of the present utility model is:

As shown in Figure 1, refrigerator (external door does not draw) top is refrigerating chamber (1), and the bottom is drawer type refrigerating chamber (7); Door curtain (3) is made with the soft transparent material in of the present utility model, and its width is slightly larger than the refrigerating chamber width to be enough to it is covered fully, and length is about the twice of refrigerating chamber height, and upper winding shaft (2) is fixed in the upper end, and lower winding shaft (6) is fixed in the lower end; Have window (4) in the place of about 1/2 length of door curtain, its size is suitable with the refrigerating chamber interlayer, and window can be to open wide fully, also can have and hold court from behind a screen; The window lower limb embeds the hard plastic board bar as handle (5).

Spool is installed in refrigerating chamber two ends up and down, makes the door curtain on it cover refrigerating chamber fully.

Accompanying drawing 2 is spool structure front views of present embodiment.

As shown in Figure 2, the spool of present embodiment is made (11) with the rigid plastics rod, the one end is equipped with spring backrush device (15), the backrush direction of two spools is opposite, specifically, it is to be involved in that door curtain scrolls up upper winding shaft, is to roll out to lower winding shaft, the downward scrolling of door curtain is to roll out to upper winding shaft, is to be involved in to lower winding shaft.

As shown in Figure 2, member (8) and (13) are used for supporting reel (11), and its external diameter cooperates with the id tolerance of spool, and spool can be free to slide thereon.Member (8) and (13) are with being fixed on the freezer wall someway.

As shown in Figure 2, the roundel (9) in the member (8) is used for fixing spring (15).Spring the inner (16) embeds the slit in the roundel, and outer end (14) embed the slit (10) of spool inwall.

Also make with rigid plastics the member of present embodiment (8) and (13).

As shown in Figure 2, the groove on the spool (12) is used for embedding the upper end or the lower end of door curtain.

The upper and lower volume axle construction of present embodiment is the same.

Regulating two springs makes the backrush elastic force of appropriateness and makes the elastic force of upper winding shaft be slightly larger than lower winding shaft, make door curtain under normal conditions the doorframe that has more of its length partly be involved in the upper winding shaft, present embodiment is unkitted the position and lock releasing device, when needs are got thing from refrigerating chamber, with handle window is pulled to desired location, because the auto reeling effect of spool up and down, pull out the soft curtain of some length from upper winding shaft, lower winding shaft just is involved in the soft curtain of respective length, and therefore door curtain always is close on the refrigerating-chamber door and stops the loss of cold air.Get thing and finish and unclamp handle, door curtain is used the roll recovery normality because of elastic force, and under normal conditions, window still leaves a slit and is not involved in fully, can make cold air enter external door thing frame.

Roll set has contact with around power actuated spring assembly, the ratchet that plays the locking release action and can adopt ready-madely in the utility model, also can design separately.
