Referring to fig. 1 and 2, a refrigeration appliance 1 includes an insulated cabinet 2. The cabinet 2 has a first storage compartment 3 and a second storage compartment 4, each surrounded by a plurality of insulating walls and having a front opening. The first storage compartment 3 and the second storage compartment 4 are separated by an insulated partition wall 5.
In this embodiment, the first and second storage compartments 3, 4 are defined by first and second substantially box-shaped bladders 6, 7, respectively, and the partition wall 5 is formed by a bottom wall of the first bladder 6 and a top wall of the second bladder 7 and an insulating layer therebetween.
In this embodiment, the first holding compartment 3 is located in the upper part of the refrigeration appliance 1 and the second holding compartment 4 is located in the lower part of the refrigeration appliance 1. The first storage compartment 3 is a refrigerating compartment and the second storage compartment 4 may be a freezing compartment.
The refrigeration appliance 1 comprises a bar-shaped cross member 8 spanning across the front ends of a pair of side insulating walls 22 of the first storage compartment 3 and a partition plate 15 supported at its front end on the cross member 8. The first storage compartment 3 is divided into an upper storage compartment 9 located above the dividing plate 15 and a lower storage compartment 10 located below the dividing plate 15, with respect to the cross members 8 and the dividing plate 15.
The front surface of the cross member 8 may be substantially in the same plane as the front end surface of the casing 2. The refrigeration appliance 1 includes first and second doors 11 and 12 to close the upper and lower storage compartments 9 and 10, respectively. The second packing compartment 4 is closed by a third door 13.
The first door 11 and the second door 12 may be hinged to a front side of the cabinet 2. The refrigerator 1 comprises a hinge 14 which is fastened to the transverse beam 8. In this embodiment, the first door 11 and the second door 12 are each connected with a hinge 14. Thus, the cross member 8 bears the weight of the first door 11.
Referring to fig. 4 in conjunction with fig. 2, in this embodiment, the partition plate 15 is formed of a shelf on which food can be stored. The partition plate 15 may include a glass plate 151 and a bezel 152 attached to at least one edge of the glass plate 151. As shown in fig. 4, the bezel 152 includes a front frame portion 1521, a rear frame portion 1522, and a pair of side frame portions 1523 fixed to the front edge, the rear edge, and the side edges of the glass plate 151, respectively. The bezel 152 is preferably made of plastic. The bezel 152 can be disposed along only one or more edges of the glass sheet 15, such as only the front and back edges.
It should be appreciated that in an alternative embodiment, divider plate 15 may also be integrally formed from metal, plastic, and/or other suitable material.
The partition plate 15 includes a plurality of through holes that fluidly communicate the upper reservoir chamber 9 and the lower reservoir chamber 10. In this embodiment, the partition plate 15 includes a plurality of first through holes 1524 at the rear end of the partition plate 15 and a plurality of second through holes 1525 at the front end of the partition plate 15. The first through hole 1524 is preferably formed in the rear frame portion 1522, and the second through hole 1525 extends through the front frame portion 1521.
The front end of the partition plate 15 is supported on the cross member 8. The front portion of the cross member 8 is higher than the rear portion with a step portion 812 formed therebetween, and the partition plate 15 is supported on the rear portion of the cross member 8. The height of the step 812 may be determined depending on the thickness of the partition plate 15, and is preferably substantially equal to the thickness of the partition plate 15, so that the partition plate 15 and the front portion of the cross member 8 are at the same level.
The front edge of the divider 15 and/or the step 812 may be provided with a notch (not shown) to allow a finger or tool to be inserted from the upper side under the divider 15 to remove the divider 15.
Both sides of the partition plate 15 are also supported by the support structures 221 on the inner sides of the pair of side heat insulating walls 22 of the box body 2. Support structure 221 may be formed directly on bladder 6 or may be manufactured separately from bladder 6 and then secured to bladder 6.
The refrigeration appliance 1 comprises an evaporator 16 for cooling the first storage compartment 3. The evaporator 16 may be located within the insulating layer of the rear insulating wall 21 of the first storage compartment 3 and affixed to the first internal bladder 6 to cool the first storage compartment 3 by the cooled first internal bladder 6. In an alternative embodiment, the evaporator 16 can also be located within the first storage compartment 3, for example, in front of the rear portion of the first bladder 6 adjacent the back of the first bladder 6.
The evaporator 16 is located above the partition plate 15 and preferably at a position above the back of the first liner 6. The upper storage compartment 9 is cooled, particularly by the air near the rear insulating wall 21, and the cold air having a low temperature naturally sinks.
The cool air cooled by the evaporator 16 in the upper storage compartment 9 sinks to the lower storage compartment 10 through the first through hole 1524, and the air having a higher temperature at the top of the lower storage compartment 10 returns to the upper storage compartment 9 through the second through hole 1525, thereby forming natural convection of air between the upper storage compartment 9 and the lower storage compartment 10. This facilitates a relatively even distribution of the temperatures of the upper and lower storage compartments 9, 10.
In order to avoid some areas inside the lower storage compartment 10 from being excessively cold due to air deposition, as shown in fig. 2 and 3, the refrigeration appliance 1 includes a blocking portion 26 extending from the inside of the rear wall 21 of the cabinet 2 toward the upper storage compartment 9, the blocking portion 26 being adjacent to the partition plate 15 and overlapping the rear end of the partition plate 15 in the longitudinal direction.
The air is rapidly cooled at the inner container 6 attached with the evaporator 16, the cooled air sinks along the back of the inner container 6, when the cold air meets the blocking part 26, the flow direction is changed to advance along the partition plate 15, part of the cold air continues to sink through the first through hole 1524 at the rear part of the partition plate 15, and the other cold air can be left in the upper storage chamber 9 to exchange heat with the articles in the upper storage chamber 9.
The blocking portion 26 preferably extends over the entire width of the back of the inner container 6. The top surface of the blocking portion 26 may extend forward horizontally or upward to prevent the cool air from being directly directed to the first through hole 1524.
The lower surface of the blocking portion 26 may be at least partially in contact with the upper surface of the partition plate 15. In this embodiment, the rear end of the partition plate 15 is continuously in contact with the lower surface of the blocking portion 26 over the entire width, which is advantageous in maximally preventing the cool air from sinking between the rear end of the partition plate 15 and the back of the inner container 6.
A horizontal groove 2212 may be formed between the support structure 221 and the blocking portion 26, and corner portions 1527 of both side edges and a rear edge of the partition plate 15 are inserted into the horizontal groove 2212, which is advantageous in limiting the shaking of the rear end of the partition plate 15 in the longitudinal direction, particularly the shaking of the partition plate 15 in the up-down direction during the transportation of the refrigeration appliance 1, thereby facilitating the packaging and transportation of the refrigeration appliance 1.
Preferably, at least one drawer, for example, two drawers 28, 29, are disposed in the lower storage compartment 10. There is a space between each drawer 28, 29 and the back of the first liner 6. In a preferred embodiment, the inner side of the back of the first liner 6 can be provided with a projection 25 corresponding to each drawer 28, 29, the drawers 28, 29 being not further movable backwards when the rear of the drawers 28, 29 rest against the projections 25, so that there is a space between the back of the liner 6 and the drawers.
When the cold air enters the lower storage chamber 10 through the partition plate 15 and meets the drawer 28 located in the lower storage chamber 10, the cold air is forcibly branched, a part of the cold air enters the drawer 28, and the other part of the cold air continues to sink; when the cold air, which continues to sink, meets the drawer 29 in the lower storage room 10, it is forcibly branched again, and a portion enters the drawer 29 and another portion sinks to the bottom of the lower storage room 10. After heat exchange with food, the air having a high temperature in the lower storage chamber 10 is circulated by passing through the second through holes 1525 formed in the front ends of the partition plates 15 and moving upward to the upper storage chamber 9.
Preferably, the stopper 26 terminates in a continuous region between the rear edge of the rear frame portion 1522 and the rear edge of the first through hole 1524 in the front-rear direction, that is, the stopper 26 and any one of the first through holes 1524 are spaced apart in the front-rear direction such that the stopper 26 does not overlap the first through hole 1524 in the longitudinal direction. This is advantageous in improving the utilization of the first via 1524.
In a preferred embodiment, the refrigeration appliance 1 comprises an adjustment mechanism to adjust the size of the at least one first through hole 1524 to control the convective heat exchange of the upper storage compartment 9 and the lower storage compartment 10.
According to a particularly preferred embodiment of the invention, the blocking portion 26 forms a water receiving channel 23 to receive condensed/defrosted water. The water receiving tank 23 has a water outlet 231 connected to a water discharge pipe 24 to discharge the condensed/defrosted water out of the first storage compartment 3, for example, into a water receiving tray (not shown) located in the machine room. Barrier 26 is preferably of one-piece construction with first bladder 6.
In the above embodiment, the upper storage chamber 9 and the lower storage chamber 10 perform air convection through at least one first through hole and at least one second through hole provided on the partitioning plate, however, in an alternative embodiment, the upper storage chamber and the lower storage chamber may also perform natural air convection through a gap provided between the rear end of the partitioning plate 15 and the first inner bag 6 and a gap between the partitioning plate 15 and the cross beam 8.
The various embodiments of the individual components described in connection with fig. 1 to 4 may be combined with each other in any given way to achieve the advantages of the invention. In addition, the present invention is not limited to the illustrated embodiments, and other means than those shown may be generally used as long as the same effects are obtained.
