Description

Duct structure of single-door intermittent cooling type refrigerator

The present invention relates to the household electrical appliance refrigeration technology field, is a kind of wind path structure that is particularly suitable for indirect-cooling simple gate refrigerator.It is detachable and can change the dividing plate that placement location has the air channel by being positioned at refrigerator, is positioned at the interlayer air-return duct on the screen of air channel and the closable air door that connects with it forms.

In existing indirect-cooling (or claiming air-cooled, frost-free type) simple gate refrigerator, as above water chestnut BD--110W refrigerator, its wind path structure (shown in the accompanying drawing 1) is, cold wind by the evaporimeter generation, under the blowing effect of the fan after being positioned at the air channel screen, enter in the case, and from being positioned at the return air inlet Returning evaporimeter on the screen of air channel.Therefore, the temperature inside the box is uniformly, if regulate temperature, also can only change by FCL one.Like this concerning the simple gate indirect cooling refrigerator, general structure is rational, but for satisfying the further demand of consumer, improve the refrigerator function of use--as required space in the whole case is become chamber between two of freezing, the refrigerations of variable volume, and each room temperature degree homogeneous and controllable (is not higher than-18 ℃ as freezing compartment's temperature, the refrigerator room temperature is 0--10 ℃) time, this kind wind path structure just is unequal to having born.

The objective of the invention is to propose a kind of wind path structure that increases simple gate indirect cooling refrigerator function of use.

Purpose of the present invention can reach by following measure:

1. in the wind path of existing simple gate refrigerator, in the screen of air channel, increase one or more interlayer air-return ducts; As 1 described interlayer air channel on, direction is provided with a plurality of air doors and makes it to be in closed condition in case; 3. in case, set up one dismountable with as 2 described air doors link in the dividing plate in air channel is arranged, be divided into space in the case freezing and refrigerate chamber between two, and, volumes freezing, two chambers of refrigeration are changed with the variation of this dividing plate position in case.

The drawing of this Figure of description is described as follows:

1. Fig. 1 is the wind path structural representation of existing Shangling brand BD-110W refrigerator.

2. Fig. 2 is among a kind of embodiment of the present invention, the wind path structural representation of dividing plate when a certain position.

3. in the wind path structure most preferred embodiment that Fig. 3 proposes for the present invention, the schematic diagram of air door.

4. in the wind path structure most preferred embodiment that Fig. 4 proposes for the present invention, the schematic diagram of dividing plate.

The present invention does following further describing with reference to accompanying drawing:

1. the dividing plate 11(that packs into sees accompanying drawing 2), open the corresponding air door 13 that is positioned on the air channel screen 12, the air outlet 14 at dividing plate rear portion is communicated with it.At this moment, cold wind circulation path in the refrigerator is: by the cold wind of evaporimeter 15 generations, under the blowing effect of fan 16, through after the freezing compartment, by air inlet 17 and ventilative mouthful 18 shunting of dividing plate front portion, most of air inlet that flows into, air channel 20, air outlet and the air door in dividing plate enters the air-return duct 21 in the screen of air channel, Returning evaporimeter forms freezing compartment's wind path circulation; Another fraction flows into ventilative mouthful, behind the refrigerator chamber, by former return air inlet 19 Returning evaporimeters on the screen of air channel, forms the wind path circulation of refrigerator chamber.

2. the temperature that can regulate the refrigerator chamber by the size of regulating ventilative mouthful is regulated the ventilative mouthful of area ratio with air inlet, can regulate the cold distribution of two chambers, that is to say, under the cooperation of temperature controller, can regulate the temperature of two chambers respectively.

3. remove this dividing plate, close corresponding air door, make the interlayer air-return duct inoperative, refrigerator promptly recovers its original wind path structure, keeps original function.

4. owing on the screen of air channel a plurality of air doors are arranged, dividing plate just has a plurality of positions to place in case, and therefore, volume freezing, the refrigerator chamber just can be adjusted as required in the case.

5. be positioned at that air door on the screen of air channel and air channel screen work are movable to be linked, its opening and closing, can be rotate or slide; The means of operation can be direct or indirect; The means that drive can be manually or use other external force; Packing into of the unlatching of air door and dividing plate, can be move respectively or the interlock.

6. the area ratio of ventilative mouthful size and ventilative mouthful and air inlet on the dividing plate can manually or be used the temperature control air door adjustment, also can directly adjust during fabrication by the serviceability temperature (not being higher than-18 ℃ as freezing compartment, 0--10 ℃ of refrigerator chamber) of being scheduled to.

7. when a plurality of interlayer air-return duct was arranged in the screen of air channel, the wind path structure of refrigerator was the parallel combination of many above-mentioned wind paths, and like this, flowing of cold wind is more even.

Most preferred embodiment of the present invention is: have only an interlayer air-return duct in the screen of air channel, be positioned at the binding (shown in the accompanying drawing 3) that rotates of air door on the screen of air channel and air channel screen, its relies on gravity normally closed; The air outlet at dividing plate rear portion is triangular shape projection (shown in the accompanying drawing 4), and when packing dividing plate into, air outlet backs down air door corresponding on the screen of air channel, constitutes wind path, and all the other air doors are then closed naturally; Ventilative mouthful size and the ventilative mouthful of area ratio with air inlet are not higher than-18 ℃ by freezing compartment, directly adjust during fabrication in 0--10 ℃ of refrigerator chamber.

The present invention compared with prior art has the following advantages:

1. the wind path structure by a kind of single-door intermittent cooling type refrigerator has increased the use function of refrigerator, and dividing plate can be placed many places in refrigerator, space in the case is divided into as required chamber between two of freezing, the refrigerations of variable volume, the convenient use.

2. owing to be indirect-cooling, two compartment temperatures after the separation are even, no matter what position dividing plate is in, freezing compartment's temperature keeps not being higher than-18 ℃, 0--10 ℃ of refrigerator chamber, and ventilative mouthful size and ventilative mouthful directly adjust during fabrication with the area ratio of air inlet, and the user need not to adjust, just like the four-star two-door household refrigerator-freezer of use.

3. the air outlet behind the dividing plate backs down corresponding air door when dividing plate is packed into, constitutes wind path automatically, handled easily.Remove dividing plate, air door is closed automatically, recovers the function of indirect-cooling simple gate refrigerator.

4. have only an interlayer air-return duct in the screen of air channel, make simple.
