Description
Technical Field
The invention relates to a freezing and refrigerating technology, in particular to a refrigerator.
Background
Existing air-cooled refrigerators may generally include a freezer compartment located below and a refrigerator compartment located above and a circulation duct. The circulating air flow for the refrigerating chamber is generally led to the bottom of the evaporator from the air outlet of the refrigerating chamber, and the return air of the refrigerating chamber passes through the evaporator fins, so that the air is cooled and refrigerated by the evaporator, and then is blown to the refrigerating chamber for refrigeration by a fan. When the circulating air flows out of the air outlet of the refrigerating chamber, moisture in food is taken away, and the moisture in cold air frosts on the surface of the evaporator when the circulating air is refrigerated by the evaporator. The accumulated more frost seriously affects the heat transfer of the evaporator and reduces the operation efficiency of the refrigerator, so that the existing air-cooled refrigerator is required to be stopped for defrosting after a period of operation, and the frequent stopping defrosting of the refrigerator greatly increases the energy consumption. In addition, when the air cooled and frozen by the evaporator is blown into the refrigerating chamber again, the air is relatively dry due to the fact that the air is cooled and dehumidified by the evaporator, and when the air is sent into the refrigerating chamber, the humidity of the refrigerating chamber is very low, the preserved food is dehydrated and air-dried, and the preservation of the food is very unfavorable.
In order to solve the technical problem, an air return port can be added on an air return air duct of the air-cooled refrigerator, so that a part of return air of the refrigerating chamber enters the next air supply cycle without being cooled by an evaporator. The way can reduce the frosting of the evaporator to a certain extent and slow down the air drying degree of food, however, in the process of mixing the high-temperature high-humidity gas introduced by the air return opening with the low-temperature dried gas passing through the evaporator at the fan or other places, the problem of frosting or icing at the fan or other mixed places easily occurs, the rotating speed of the fan is reduced, and finally the temperature imbalance of the refrigerating chamber and the freezing chamber is caused.

Detailed Description
Fig. 1 is a schematic structural view of a refrigerator according to an embodiment of the present invention, and fig. 2 is a schematic sectional view taken along a sectional line A-A in fig. 1. Referring to fig. 1 and 2, the refrigerator 1 includes a cooler 10, a cabinet 20, and a drain plate 30. Specifically, the cooler 10 is configured to exchange heat with a gas flowing therethrough, thereby changing the temperature of the gas. The box 20 has a cooling chamber 21 and a return air duct 22 defined therein, wherein the cooler 10 is disposed in the cooling chamber 21, and the cooling chamber 21 has a first return air inlet 211 communicating to an upstream side of the cooler 10 and a second return air inlet 212 communicating to a downstream side of the cooler 10 in a gas flow direction in the cooling chamber 21. The return air duct 22 communicates with the first return air port 211 and the second return air port 212. The flow-guiding plate 30 is located within the cooling chamber 21 and is configured such that the gas entering the cooling chamber 21 through the second return air inlet 212 is mixed with at least part of the gas entering the cooling chamber 21 through the first return air inlet 211 and flowing through the cooler 10 at the flow-guiding plate 30. Thereby, the high temperature and high humidity gas entering the cooling chamber 21 through the second return port 212 and at least part of the low temperature dry gas after heat exchange through the cooler 10 can be mixed in advance at the flow guiding plate 30. In the mixing process, the temperature of the high-temperature and high-humidity gas is reduced, the saturation capacity of the gas is reduced, redundant water is separated out, and frosting is formed at the drainage plate 30, so that the influence of frosting at other parts in the cooling chamber 21 on the performance of the refrigerator is avoided, and the service performance of the refrigerator 1 is improved. In an embodiment of the present invention, the cooler 10 is preferably an evaporator to cool the gas flowing therethrough. In other embodiments of the invention, the cooler 10 may also be other types of heat exchangers.
In some embodiments of the present invention, at least one storage compartment for storing items is also defined within the housing 20, each storage compartment being in communication with a return air duct 22 for delivering return air to the cooling compartment 21 through the return air duct 22. Further, an air supply duct communicating the cooling chamber 21 and the storage compartment may be defined in the case 20 such that the air cooled by the cooler 10 is supplied to the storage compartment through the air supply duct, thereby forming a cooling cycle among the storage compartment, the return air duct 22, the cooling chamber 21, and the air supply duct in the case 20.
Further, the at least one storage compartment may include a refrigerating compartment (not shown) and a freezing compartment 23, and the cooling compartment 21 is located behind the freezing compartment 23. The latter is referred to herein as the refrigerator 1 is in normal use. The refrigerating compartment and the freezing compartment 23 may be arranged adjacently up and down, and have different temperature ranges inside, so as to realize different demands for storage of articles. The cooling chamber 21 and the freezing chamber 23 may be disposed adjacently in the front-rear lateral direction. It will be appreciated by those skilled in the art that in other embodiments of the present invention, the at least one storage compartment may also include a quick-freeze compartment, a variable temperature compartment, and/or an ice-making compartment, etc., with different storage compartments having different temperature ranges for storing different items and/or achieving different storage requirements.
In some embodiments of the present invention, the refrigerator 1 further includes a blower 40 disposed within the cooling chamber 21. And is located downstream of the cooler 10 in the direction of gas flow within the cooling chamber 21 to drive the gas cooled via the cooler 10 out of the cooling chamber 21. The second return air inlet 212 is located between the fan 40 and the cooler 10 in the direction of the flow of the gas in the cooling chamber 21, so that the gas that is led from the return air duct 22 to the cooling chamber 21 via the second return air inlet 212 is located between the fan and the cooler 10, i.e. the second return air inlet 212 is located downstream of the cooler in the direction of the flow of the gas in the cooling chamber 21 and upstream of the fan 40. The gas subjected to heat exchange by the cooler 10 also flows toward the fan 40 by the driving of the fan 40, thereby forming a mixing region between the fan 40 and the cooler 10 in which the gas introduced into the cooling chamber 21 through the second return air port 212 and at least part of the gas subjected to heat exchange by the cooler 10 are mixed. Specifically, the cooler 10 is located at a lower portion of the cooling chamber 21, the blower 40 is located at an upper portion of the cooling chamber 21, the second air outlet 212 is located at an upper portion of the cooling chamber 21, and between the cooler 10 and the blower 40, the first air outlet 211 is located at a lower portion of the cooling chamber 21, and upstream of the cooler 10 in a gas flow direction within the cooling chamber 10. In the embodiment of the present invention, the flow direction of the air in the cooling chamber 21 is from bottom to top, and the flow direction of the air in the return air duct 22 is from top to bottom, which is shown by the straight arrow in fig. 1.
In the refrigerator 1 of the present invention, a part of the gas for circulation is not cooled by the cooler 10, but is mixed with at least a part of the gas flowing through the cooler 10 downstream of the cooler 10 to reach a refrigerating temperature, and moisture in the gas not cooled by the cooler 10 may be continuously returned to the corresponding storage compartment (e.g., refrigerating compartment). Therefore, at least part of the moisture in the refrigerating compartment can be prevented from frosting on the cooler 10 while refrigerating, the frosting quantity on the cooler 10 is reduced, the defrosting cycle is prolonged or the time of single defrosting is shortened, and therefore the power consumption of the refrigerator 1 is reduced, and the refrigerator 1 is more energy-saving.
In some embodiments of the present invention, the flow-guiding plate 30 may extend from the second return air inlet 212 into the cooling chamber 21 such that the flow-guiding plate 30 is located between the blower 40 and the cooler 10 in the gas flow direction in the cooling chamber 21, and such that the gas passing through the second return air inlet 212 flows into the cooling chamber 21 at the side of the flow-guiding plate 30 facing the cooler 10. That is, a mixing region for mixing the gas introduced into the cooling chamber 21 through the second return port 212 and at least part of the gas subjected to heat exchange through the cooler 10 is located at a side of the flow guiding plate 30 facing the cooler 10, i.e., the mixing region is located below the flow guiding plate 30. In other words, the gas introduced into the cooling chamber 21 through the second return port 212 and the gas subjected to heat exchange through the cooler 10 are mixed at the flow-guiding plate 30 (upstream of the blower 40) and then flow to the blower 40, so that frost is condensed at the flow-guiding plate 30.
Further, the flow guiding plate 30 may be a plate-shaped member made of a metal material to improve the heat conductive property of the flow guiding plate 30. Preferably, the drainage plate 30 can be made of materials with better heat conduction performance such as copper, iron and the like.
Fig. 3 is a schematic structural view of a cooling chamber and a return air duct of a refrigerator according to an embodiment of the present invention, and fig. 4 is a schematic structural view of a cooling chamber of a refrigerator according to an embodiment of the present invention. Referring to fig. 3 and 4, the cooling chamber 21 and the return air duct 22 may be partitioned by a partition plate 24, and the first and second return air inlets 211 and 212 may be opened on the partition plate 24. The proximal end of the flow guiding plate 30 near the second air return opening 212 may abut against the partition plate 24, so as to avoid the gas guided into the cooling chamber 21 through the second air return opening 212 from directly flowing to the blower 40 located at the downstream of the flow guiding plate 30 without being mixed with the heat exchanged gas, thereby avoiding frosting on the blower 40 as much as possible. Further, the proximal end of the flow-guiding plate 30 may be fixed to the partition plate 24 or both sides of the flow-guiding plate 30 may be fixed to the wall of the tank defining the cooling chamber 21.
Further, a square area is defined within the edge of the flow guiding plate 30, the width of the square area in the width direction parallel to the partition plate 24 is W, the maximum dimension of the second air return opening 212 in the width direction is W1, and W.gtoreq.W 1. The width direction is the direction in which the edge of the flow-guiding plate 30 parallel to the partition 24 is located. That is, the width of the square area in the width direction is equal to or greater than the maximum dimension of the second return air opening 212 in that direction. Further, the size of the return air duct 22 in the width direction is W2, and W < W2, that is, W1. Ltoreq.W < W2. Specifically, the cross section of the return air duct 22 may be square, circular or other shape, and when the cross section thereof is square, W2 is the width of the return air duct 22 in the width direction; when the cross section is circular, W2 is the diameter of the return air duct 22; when the cross section is of other irregular shape, W2 is the largest dimension of the return air duct 22 in the width direction at the second return air opening 212. The second air return opening 212 may be elongated, square, round hole or other irregular shape, and when the second air return opening 212 is elongated or square, W1 is the width thereof extending in the width direction; when the second air return opening 212 is in a circular hole shape, W1 is the diameter thereof; when the second air return opening 212 is irregularly shaped, W1 is the maximum dimension of the second air return opening 212 in the width direction.
Fig. 5 (a) is a schematic structural view of a drainage plate according to one embodiment of the present invention, fig. 5 (b) is a schematic structural view of a drainage plate according to another embodiment of the present invention, and fig. 5 (c) is a schematic structural view of a drainage plate according to still another embodiment of the present invention. Referring to fig. 5 (a) to 5 (c), in some embodiments of the present invention, the edge of the drainage plate 30 is at least one or more of linear, curved or toothed. That is, the drainage plate 30 may be a square plate, and four edges thereof are all in a straight line shape. The drainage plate 30 may also be an irregularly shaped plate-like member, such as in fig. 5 (b), in which two edges of the drainage plate 30 are rectilinear and the other two edges are curvilinear; as further shown in fig. 5 (c), two edges of the drainage plate 30 are straight and the other two edges are tooth-shaped. In other embodiments of the invention, all or part of the edges of the drainage plate 30 may be shaped otherwise.
It will be appreciated by those skilled in the art that whether the drainage plate 30 is square or irregularly shaped, the interior of its edges will define a square area. When the flow guiding plate 30 is a square plate, the square area is the entire flow guiding plate 30, and W is the width of the square flow guiding plate 30 in the width direction; when the drainage plate 30 is irregularly shaped, for example, as shown in fig. 5 (b) and 5 (c), the square area thereof is shown by the dashed line box in fig. 5 (b) and 5 (c), and W is the dimension of the square area in the width direction.
In some embodiments of the invention, referring to FIG. 4, the distal end of the flow-directing plate 30 is at a vertical distance L from the baffle 24, the geometric center of the blower 40 is at a vertical distance L1 from the baffle 24, the edge of the blower 40 is at a nearest vertical distance L2 from the baffle 24, and L2 < L1. That is, the vertical distance that the flow directing plate 30 extends from the partition 24 into the cooling chamber 21 is between the closest vertical distance of the fan 40 from the partition 24 and the vertical distance of the geometric center of the fan 40 from the partition 24. Therefore, the air guided into the cooling chamber 21 by the second air return port 212 and at least part of the air subjected to heat exchange by the cooler 10 are fully and uniformly mixed, and the mixed air is not influenced to continuously flow to the storage compartment of the refrigerator 1 by the fan 40, so that the mixed flow effect of the air guided by the air guide plate 30 and at least part of the air subjected to heat exchange by the cooler 10 is improved.
Further, the drainage plate 30 may be placed along a horizontal direction or placed obliquely, and the included angle α (see fig. 1) formed by the oblique placement and the horizontal direction is defined as: alpha is more than or equal to-45 degrees and less than or equal to 45 degrees, so as to have better guiding and mixing effects. When the flow guiding plate 30 extends horizontally in the cooling chamber 21, the vertical distance L between the distal end of the flow guiding plate 30 and the partition plate 24 is the length of the flow guiding plate 30 in the direction perpendicular to the partition plate 24; when the flow guiding plate 30 extends obliquely in the cooling chamber 21, the vertical distance L from the distal end of the flow guiding plate 30 to the partition plate 24 is the length of the projection of the flow guiding plate 30 on the horizontal plane in the direction perpendicular to the partition plate 24, i.e. the vertical distance from the projected distal end to the partition plate 24.
In some embodiments of the present invention, the flow-guiding plate 30 is arranged with an electrically controlled heating device 31 to controllably defrost the flow-guiding plate 30. In particular, the heating means 31 may be a heating wire wound around the surface of the drainage plate 30, an electric heating film coated on the surface of the drainage plate 30, or other type of heating member. The heating device 31 may be electrically connected with a main control board of the refrigerator 1 to periodically remove frost on the drainage plate 30 under the control of the main control board. The activation period and heating power of the heating means 31 may be dependent on the specific amount of frost formed on the drainage plate 30. The defrost water generated by defrosting the drain plate 30 can be discharged through the drain pipe inside the refrigerator 1.
In other embodiments of the present invention, the cooler 10 has a heating wire 11 for defrosting the same, and the flow-guiding plate 30 is thermally connected to the heating wire 11 through a heat transfer device to defrost the flow-guiding plate 30 by heat generated from the heating wire 11. Specifically, the heating wire 11 may be provided at the bottom of the cooler 10, and may be energized to start after the cooler 10 is operated for a certain period of time or after frost on the cooler reaches a predetermined level, thereby heating and defrosting the cooler 10. The heat transfer device may be a heat pipe, a heat transfer plate or other type of heat transfer component, and the heat transfer device may transfer part of the heat generated by the heating wire 11 to the drainage plate 30 through heat radiation, heat conduction or other heat transfer modes, so as to defrost the drainage plate 30. The defrost water generated by defrosting the drain plate 30 can be discharged through the drain pipe inside the refrigerator 1.
