Detailed Description

Fig. 1 is a schematic structural view of a refrigerator according to an embodiment of the present invention, and referring to fig. 1, the refrigerator 1 of the present invention includes a cabinet 10 defining a storage compartment 11, and a storage device 40 disposed in the storage compartment 11. Specifically, the rear side of the storage compartment 11 may be provided with an air duct cover 30. The storage compartment 11 may be a refrigerating compartment having a refrigerating storage environment, or may be a temperature-changing compartment or other fresh-keeping compartment.

Fig. 2 is a partial structural view of a refrigerator according to an embodiment of the present invention, fig. 3 is a schematic rear view of a portion of an air duct cover plate of the refrigerator according to an embodiment of the present invention, fig. 4 is a schematic enlarged view of a portion a of fig. 2, fig. 5 is a schematic exploded view of the structure shown in fig. 2, and fig. 6 is a schematic structural view of a storage device according to an embodiment of the present invention. Referring to fig. 2 to 6, the refrigerator 1 of the present invention further includes an evaporator 20 for supplying cold to the storage compartment 11, and the evaporator 20 is located at the rear side of the duct cover 30.

Specifically, the refrigerator 1 further includes a humidifying circulation air passage 51, a water reservoir 52, a humidifying module 53, and a humidifying fan 54. The storage device 40 is disposed in the storage compartment 11 and has an air supply outlet 41 and a humidifying air return outlet 46. The humidifying circulation air passage 51 is located outside the storage compartment 11, and both ends thereof are respectively communicated with the air supply outlet 41 and the humidifying return air inlet 46. The reservoir 52 is located below the evaporator 20 and stores a part of the condensed water generated from the evaporator 20. The first end 531 of the humidification module 53 is located in the reservoir 52 to adsorb the condensed water inside the reservoir 52, and the second end of the humidification module 53 extends into the humidification circulation air passage 51. The humidifying fan 54 is disposed in the humidifying circulation air path 51 and configured to be controlled to start when the storage device 40 needs to be humidified, so as to promote the airflow flowing into the humidifying circulation air path 51 through the humidifying return air inlet 46 to flow into the storage device 40 through the air supply outlet 41 after flowing through the humidifying module 53.

Since the humidification module has a function of adsorbing water, the condensed water adsorbed by the first end 531 can be distributed over various regions of the humidification module 53 by capillary force, i.e., the second end 532 of the humidification module 53 also contains water. When the storing device 40 needs to be humidified, the humidifying fan 54 disposed in the humidifying circulation air passage 51 is activated to promote the air flow to circulate between the storing device 40 and the humidifying circulation air passage 51. When the airflow passes through the second end 532 of the humidification module 53 in the humidification circulation air passage 51, a part of moisture contained in the second end 532 is taken away, and the humidity is increased, so that the aim of quickly humidifying the storage device 40 is fulfilled. Because the structures related to humidification, such as the water storage tank 52, the humidification circulation air path 51, the humidification module 53 and the humidification fan 54, are all positioned outside the storage compartment 11, only two ends of the humidification circulation air path 51 are communicated with the air supply outlet 41 and the humidification air return inlet 46 of the storage device 40, the purpose of quickly humidifying the storage device 40 is achieved, and the humidification structures do not affect the storage compartment 11.

Further, a humidifying circulation air path 51 may be formed in the duct cover 30. Correspondingly, the water storage tank 52, the humidifying module 53 and the humidifying fan 54 are all positioned on the air duct cover plate 30, so that the structure in the storage chamber 11 is simplified, and the influence on the size of the space in the storage chamber 11 is avoided.

Specifically, the air supply outlet 41 and the humidifying air return outlet 46 are opened at the rear side of the storage device 40 so as to communicate with a humidifying circulation air passage 51 formed on the duct cover 30.

FIG. 7 is a schematic front view of a duct cover according to one embodiment of the present invention. Further, the duct cover 30 is provided with an air supply port 33 and a return air port 34 which are respectively communicated with two ends of the humidifying circulation air duct 51, and when the storage device 40 is completely arranged in the storage compartment 11 (i.e. when the storage device 40 is in a closed state), the air supply port 33 and the return air port 34 are respectively communicated with the air supply port 41 and the humidifying return air inlet 46 of the storage device 40 in a sealing manner. In order to further improve the sealing performance, sealing foam is respectively arranged between the circumferential edges of the air supply port 41 and the air supply port 33 and between the circumferential edges of the humidifying air return port 46 and the air return port 34, and the sealing foam can be respectively fixed on the circumferential edges of the air supply port 33 and the air return port 34.

In some embodiments, the refrigerator 1 further includes a humidification control damper 55, the humidification control damper 55 is disposed in the humidification circulation air passage 51 and configured to controllably open and/or close the humidification circulation air passage 51. Specifically, the humidification control damper 55 may be opened to conduct the humidification circulation air passage 51 only when the storage device 40 needs humidification. When the storage device 40 does not need humidification, the humidification control damper 55 can be closed to block the humidification circulation air passage 51, so that the humidification module 53 is prevented from affecting the humidity in the storage device 40.

Since the reservoir 52 is disposed below the evaporator 20, the temperature of the evaporator 20 is very low, which may cause condensation of condensed water stored in the reservoir 52, thereby affecting the water absorption effect of the humidification module 53.

To this end, in some embodiments, the refrigerator 1 of the present invention further includes a heating device 56, the heating device 56 being configured to be controllably activated when humidification of the storage device 40 is desired to provide heat to the reservoir 52 to cause the frost in the reservoir 52 to melt. That is to say, every time the storing device 40 needs to be humidified, the heating device 56 is started to heat the water storage tank 52, so as to ensure that liquid water is contained in the water storage tank 52 when the storing device 40 needs to be humidified, thereby ensuring the water absorption effect of the humidifying module 53, and further ensuring the good humidifying effect of the storing device 40.

Further, the heating device 56 is a heating wire or a heating sheet attached to the outer surface of the bottom wall of the reservoir 52. That is, the heating device 56 does not contact the condensate in the reservoir 52, thereby preventing the condensate from affecting the performance of the heating device 56.

In some embodiments, the refrigerator 1 further includes a water pan 81, and the water pan 81 is located below the evaporator 20 to collect condensed water generated from the evaporator 20. Specifically, the bottom of the drain pan 81 may be provided with a drain hole to timely drain the condensed water generated from the evaporator 20.

The applicant has realised that the store 40 does not need to be humidified frequently for long periods of time and therefore less water is required to humidify the store 40. As in the prior art, adsorption of all the condensed water generated by the evaporator 20 to the humidification module 53 easily causes problems such as excessive condensed water, water accumulation, and freezing, and it is necessary to consider problems such as overflow and drainage of the humidification module 53, thereby complicating the structure.

To this end, the present application further provides a reservoir 52 at a lateral side of the drip tray 81, and the top opening of the reservoir 52 communicates with the drip tray 81. Therefore, the water storage tank 52 can meet the humidification requirement only by collecting the condensed water dropping from the side of the evaporator 20, and the condensed water dropping from most other areas of the evaporator 20 is still collected and discharged through the water receiving tray 81. In addition, when the amount of the condensed water in the water storage tank 52 is too much, the condensed water can directly overflow to the water receiving tray 81, an auxiliary overflow channel is not needed to be added, the existing structure of the refrigerator is fully utilized, and the situation that the refrigerator is complex in structure, high in cost and the like due to too much additional structure is avoided.

Further, the water receiving tank 52 is a groove formed by downwardly recessing the lateral side edge of the water receiving tray 81. That is, the reservoir 52 can be directly formed by adsorption, injection molding, and other processes when the air duct cover plate 30 is formed, and an assembly structure between the reservoir 52 and the air duct cover plate 30 is omitted. Therefore, the arrangement of the water storage tank 52 does not increase any structural burden and assembly burden of the refrigerator 1, and the influence and the change on the original structure of the refrigerator are reduced to the maximum.

In some embodiments, the second end 532 of the humidification module 53 covers the flow surface of the humidification circulation air path 51 at the second end 532, so that all the air flow in the humidification circulation air path 51 flowing through the flow surface flows through the second end 532 of the humidification module 53, and the humidity of all the air flow is increased as a whole.

Further, in order to reduce the obstruction of the airflow by the humidification module 53, the humidification module 53 may be a sheet-like member.

Specifically, the humidifying module 53 may be a non-woven fabric, a sponge, or other water absorbing material having water absorbing properties.

Further, the storage device 40 further comprises a moisture permeable film 47 allowing moisture inside the storage device to permeate outwards, when the humidity inside the storage device 40 is too high, too much moisture can permeate outwards through the moisture permeable film 47, and the phenomenon of condensation caused by too high humidity inside the storage device 40 is avoided.

In some embodiments, the storage device 40 can include a sealed upper lid 43 and a drawer 44. The upper sealing cover 43 is fixedly arranged in the storage compartment 11. The drawer 44 has a top opening and is configured to be disposed under the sealing upper cover 43 in a slidable manner such that the sealing upper cover 43 covers the top opening of the drawer 44 when it is in a closed state of being completely pushed into the storage compartment 11 to define a closed space between the sealing upper cover 43 and the drawer 44, and such that the drawer 44 is separated from the sealing upper cover 43 to expose the top opening of the drawer 44 when it is in an open state of being pulled out of the storage compartment 11.

Compared with the storage device with the sealed barrel body and the drawer in the prior art, the storage device 40 of the utility model forms a closed space by matching the sealed upper cover 43 and the drawer 44, on one hand, the storage device 40 can be more miniaturized, the occupied space is smaller, and the cost is lower, on the other hand, each air opening can be directly arranged on the drawer 44, the air flow for adjusting the humidity in the storage device 40 can directly flow into the drawer 44, the air flow resistance is smaller, and the humidity adjusting speed is higher.

In some embodiments, the storage device 40 may have only a moisturizing mode. In these embodiments, the refrigerator 1 further includes a switch feedback device disposed in the storage compartment 11 for detecting the opening and closing of the drawer 44. The humidification blower 54 is configured to be controllably activated after each closing action of the drawer 44 is detected by the switch feedback. That is, when the storage device 40 is used to provide a high moisture-preserving space, the humidifying fan 54 is automatically started after the drawer 44 is opened and closed each time, so as to rapidly increase the humidity in the storage device 40, and rapidly meet the requirements of fruits and vegetables.

Accordingly, the humidification control damper 55 and the heating device 56 are controllably activated after the switch feedback detects each closing motion of the drawer 44, so as to achieve the purpose of effectively humidifying the inner space of the storage device 40.

In some embodiments, the storage device 40 has a dry mode and a moisturizing mode. In these embodiments, the refrigerator 1 further includes a switch feedback device disposed in the storage compartment 11 for detecting the opening and closing of the drawer 44. The humidification fan 54 is configured to be controllably activated when the storage device 40 is in the moisturizing mode and after each closing action of the drawer 44 is detected by the switch feedback. That is, when the storage device 40 has a storage space with an adjustable dry-wet mode, the humidifying fan 54 is automatically started only after the drawer 44 in the moisturizing mode is opened and closed each time, so as to rapidly increase the humidity in the storage device 40, and enable the environment therein to rapidly meet the requirements of fruits and vegetables.

In some embodiments, the storage device 40 further includes a humidity reducing return air opening 42. A humidity reducing control damper 71 is disposed on an airflow path between the air supply opening 41 and the evaporator 20, and the humidity reducing control damper 71 is configured to be selectively opened or closed when the storage device 40 is in a dry mode to selectively allow the cooling airflow after heat exchange through the evaporator 20 to enter the storage device 40, and to be controllably closed when the storage device 40 is in a moisture preserving mode to prevent the airflow from entering the storage device 40.

Further, the refrigerator 1 further includes a compartment supply air duct 12 for supplying the cooling air flow generated by the evaporator 20 to the storage compartment 11, a compartment return air duct 13 for returning the return air flow in the storage compartment 11 to the evaporator 20, and a device supply air duct 14 for supplying the cooling air flow into the storage device 40. The device air supply duct 14 and the compartment air supply duct 12 are independent from each other, and one end of the device air supply duct 14 communicates with the evaporator 20 and the other end communicates with an air supply outlet 41 of the storage device 40. A dehumidification control damper 71 may be provided in the device supply air duct 14.

Because the device air supply duct 14 and the compartment air supply duct 12 are independent from each other, the air supply of the storage device 40 and the air supply of the storage compartment 11 are not affected by each other, and when the storage device 40 needs to supply air, whether the storage compartment 11 is in a refrigeration state, whether refrigeration is needed, the amount of refrigeration and the like do not need to be considered, that is, the air supply of the storage device 40 does not affect the temperature of the storage compartment 11. All air flows sent out through the device air supply duct 14 can flow to the storage device 40, all air flows sent out through the compartment air supply duct 12 can flow to the storage compartment 11, air supply quantity when the storage device 40 needs to supply air and air supply quantity when the storage compartment 11 needs to refrigerate are increased, and therefore humidity adjusting efficiency of the storage device 40 in a drying mode and refrigerating efficiency of the storage compartment 11 are improved.

In some embodiments, the refrigerator 1 further includes a compartment air supply damper 73, and the compartment air supply damper 73 and the dehumidification control damper 71 may be respectively disposed in the compartment air supply duct 12 and the device air supply duct 14 to controllably open or close the compartment air supply duct 12 and the device air supply duct 14, respectively.

Preferably, a compartment air supply damper 73 is disposed at an end of the compartment air supply duct 12 adjacent to the evaporator 20 for controllably opening and/or closing the compartment air supply duct 12 to selectively deliver a cooling air flow into the storage compartment 11. Preferably, the dehumidification control damper 71 may be disposed at an end of the device air supply duct 14 adjacent to the evaporator 20. Thus, the air supply of the storage compartment 11 and the air supply of the storage device 40 can be completely and independently separated.

In some embodiments, the front side of the duct cover 30 is further formed with a dehumidifying air-supplying port 31 communicating with one end of the device air-supplying duct 14, and when the storage device 40 is completely located in the storage compartment 11, the dehumidifying air-supplying port 31 is in sealed communication with the air-supplying port 41 of the storage device 40. In order to further improve the sealing performance, a sealing foam is further arranged between the air supply outlet 41 and the circumferential edge of the dehumidifying air supply port 31, and the sealing foam can be fixed on the circumferential edge of the dehumidifying air supply port 31.

In some embodiments, the number of the storage devices 40 may be one, two, or more than two, and when the number of the storage devices 40 is two, two storage devices 40 may be arranged side by side in the transverse direction at the bottom of the storage compartment 11. Accordingly, the number of the structures related to humidification is kept consistent with the number of the storage devices 40.

The refrigerator 1 of the present application is a refrigerator in a broad sense, and includes not only a so-called refrigerator in a narrow sense but also a storage device having a refrigerating, freezing or other storage function, for example, a refrigerator, a freezer, and the like.

It should be further understood by those skilled in the art that the terms "upper", "lower", "front", "rear", "top", "bottom", and the like used in the embodiments of the present invention to indicate the orientation or the positional relationship are based on the actual use state of the refrigerator 1, and these terms are only used for convenience of description and understanding of the technical solution of the present invention, and do not indicate or imply that the device or component referred to must have a specific orientation, be configured and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
