Some specific embodiments of the invention will be described in detail hereinafter by way of example and not by way of limitation with reference to the accompanying drawings. The same reference numbers will be used throughout the drawings to refer to the same or like parts or portions. It will be appreciated by those skilled in the art that the drawings are not necessarily drawn to scale. In the accompanying drawings:
fig. 1 is a schematic structural view of a refrigerator according to an embodiment of the present invention;
fig. 2 is a schematic principle view of an operation of a refrigerator according to an embodiment of the present invention;
fig. 3 is a schematic partial structural view of a refrigerator according to an embodiment of the present invention.
Detailed Description
Fig. 1 is a schematic structural view of a refrigerator according to an embodiment of the present invention. As shown in fig. 1, the refrigerator according to the embodiment of the present invention may include a cabinet 10, a cooler 30, and a moisture absorption and permeation apparatus 20 as bodies. The case 10 may have a receiving space 11 and a cooling space 12 therein. The moisture-absorbing and penetrating means 20 may be located in the receiving space 11 for partitioning the receiving space 11 into a storage space 111 for storing articles and an air duct space 112 for supplying air into the storage space 111, and the moisture-absorbing and penetrating means 20 may have a first side facing the storage space 111 and a second side facing the air duct space 112.
A cooler 30 is installed in the cooling space 12 and communicates with the duct space 112 so that the cold air flow generated after cooling by the cooler 30 enters the duct space 112. Further, the accommodating space 11 is also communicated with the storing space 111 to allow the air flow in the storing space 111 to enter the cooling space 12 to be cooled by the cooler 30, and then return to flow into the storing space 111 through the air duct space 112, as indicated by the solid arrow in fig. 1. To facilitate airflow, the refrigerator in an embodiment of the present invention may further include a blower 40 installed at the outlet of the cooling space 12. The cooler 30 may be an evaporator of a compression refrigeration system or a cold sink of a semiconductor refrigeration system.
In particular, the moisture absorption and permeation device 20 of the refrigerator provided by the embodiment of the present invention is configured to: condensing at least a portion of the moisture in the storage space 111 on at least a portion of the first side as the cold air flow passes through the air duct space 112; and moving the melted moisture from the first side to the second side when the temperature in the storage space 111 increases to melt the condensed moisture, such that the cold air flow takes away the melted moisture when flowing, as indicated by the hollow arrow in fig. 1, in the flow direction of at least part of the moisture in the storage space 111.
Specifically, fig. 2 is a schematic diagram of an operation process of the refrigerator according to an embodiment of the present invention, and solid arrows in fig. 2 show a flow direction of the air flow, i.e., show an air circulation process; the hollow arrow in fig. 2 shows the flow direction of at least part of the moisture in the storage space 111, i.e. the water lock moisturizing cycle is indicated. As shown in fig. 2, when the cool air flows through the duct space 112, the temperature of the moisture absorption and permeation device 20 is lowered, and the temperature at least at a partial region of the second side of the moisture absorption and permeation device 20 is lowered. When the internal gas in the storage space 111 encounters the low temperature (negative temperature) region on the second side of the moisture absorption and permeation device 20, a frost layer is formed by condensation, and the internal gas adheres to the second side of the moisture absorption and permeation device 20, so that part of moisture in the storage compartment can be prevented from entering the cooling space 12 to form frost on the cooler 30, and the frosting amount on the cooler 30 is reduced.
When there is no cold air flow in the air duct space 112 to stop blowing air into the storage space 111, the temperature in the storage space 111 gradually increases to melt the frost layer, and even if the condensed moisture is melted, the melted moisture can permeate the moisture absorption and permeation device 20 to move from the first side of the moisture absorption and permeation device 20 to the second side of the moisture absorption and permeation device 20. When the cold air flow flows in the air duct space 112 again to cool the storage space 111, the cold air flow can bring the moisture on the second side surface of the moisture absorption and permeation device 20 into the storage space 111, so that the moisture preservation and water locking functions of the storage space 111 can be realized.
Fig. 3 is a schematic partial structural view of a refrigerator according to an embodiment of the present invention, and solid arrows in fig. 3 show flow directions of air streams; the hollow arrows in fig. 3 illustrate the penetration of at least part of the moisture within the storage space 111. As shown in fig. 3, in some preferred embodiments of the present invention, the moisture-absorbing and permeable means 20 comprises a moisture-absorbing film 21 having a first surface facing the storage space 111 and a second surface facing the air channel space 112, the first and second surfaces forming at least partial areas of the first and second sides, respectively. At least a portion of the moisture in the storage space 111 condenses on at least the first surface of the hygroscopic film 21 as the cold air flow passes through the air channel space 112. When the temperature in the storage space 111 rises to melt the condensed moisture, the melted moisture moves from the first surface of the moisture absorption film 21 to the second surface of the moisture absorption film 21. In this embodiment, the hygroscopic film 21 allows moisture on its first surface to move to its second surface (e.g., moisture can permeate from the first surface to the second surface), and it can allow a trace amount of airflow to pass, as well as prevent airflow from passing. In some further embodiments, the absorbent film 21 may be a hydrophilic film, a hydrophilic absorbent film 21, a wet wipe, a spunlaced nonwoven, or the like.
In some embodiments of the present invention, the case 10 may include a liner defining a receiving space 11. The moisture absorption and permeation device 20 may further include an air duct cover plate 22 provided inside the rear wall of the inner container, having a mounting opening thereon, and the moisture absorption film 21 is mounted to the mounting opening. In some embodiments, the duct cover 22 includes two side covers and an upper cover. The two side cover plates are arranged on the inner surface of the rear wall of the inner container in a manner of extending along the vertical direction. The upper cover plate is arranged on the inner surface of the rear wall of the inner container in a manner of extending along the horizontal direction, and the lower surface of the upper cover plate is in sealing connection with the upper edges of the two side cover plates. The absorbent film 21 is mounted to the front vertical edge of each side cover and the front lateral edge of the upper cover. The upper cover plate and each side cover plate are provided with air outlet holes. In some alternative embodiments, the rear wall of the liner is formed with a groove, and the duct cover 22 may be flat plate-shaped and disposed at the opening of the groove. The air duct cover plate 22 is provided with an air outlet and a mounting opening positioned below the air outlet.
In some embodiments of the present invention, another accommodating space, such as accommodating space 13, is further defined in the case 10, so that the accommodating space in the case 10 is plural. The further accommodation space 13 may be located below the accommodation space 11. The cooling space 12 is located at the rear of the other accommodation space 13. For example, the receiving space 11 may be a refrigerating chamber, and the other receiving space 13 may be a freezing chamber. In some embodiments of the present invention, neither the storage space 111 nor the air duct space 112 of the accommodating space 11 communicates with the cooling space 12, but communicates with the other accommodating space 13 to utilize the cold air flow in the freezing chamber.
By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described herein in detail, many other variations or modifications of the invention consistent with the principles of the invention may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
