Embodiments of the present application are described in detail below with reference to the accompanying drawings.

Referring to fig. 1 and 2, a refrigerator may include: a main body 10 forming a storage compartment, a door 20 for opening or closing the storage compartment, and a cool air supply device for supplying cool air to the storage compartment.

The refrigerating chamber door 21 is rotatably connected to the main body 10, and the freezing chamber door 22 is a drawer type door that is slidably inserted or pulled out. In other examples, the freezing chamber door 22 may be rotatably provided on the main body 10.

The cool air supply device may generate cool air using a cooling cycle for compressing, condensing, and evaporating a refrigerant, and supply the cool air to the storage chamber. The cool air supply device includes a compressor 31 for compressing a refrigerant, a condenser (not shown) for condensing the compressed refrigerant, an expansion valve (not shown) for expanding the condensed refrigerant, and an evaporator 32 for evaporating the expanded refrigerant to take heat, the compressor 31, the condenser, the expansion valve, and the evaporator 32 constituting a cool cycle in which cool air is supplied into the storage chamber. As a common component, a cool air supply fan 33 may be installed adjacent to the evaporator 32 to forcibly circulate air to blow cool air generated at the evaporator 32 into the storage compartment. The refrigerating load is controlled by adjusting the blowing amount and blowing direction of the cool air supply fan 33, adjusting the amount of circulated refrigerant, or adjusting the compression frequency of the compressor 31, so that the temperature of the storage compartment can be controlled.

The cool air supply device may include an evaporator 32 for cooling the refrigerating compartment 13 and the freezing compartment 14.

The rear end of the freezing chamber 14 may be provided with a freezing air duct 40, and the evaporator 32 and the cool air supply fan 33 constitute a cooling unit, disposed in the freezing air duct 40.

The freezing air duct 40 includes a freezing air duct cover 41, and the freezing air duct cover 41 is located at the front end of the freezing air duct 40. A refrigerating air outlet 42 is provided at an upper portion of the refrigerating air duct cover 41, and a refrigerating air return 43 is provided at a lower portion of the refrigerating air duct cover 41.

When the cooling unit cools the freezing chamber 14, referring to fig. 2 and 3 in combination, the hollow arrow in the drawing illustrates the air flow path in the freezing chamber, and hot air in the freezing chamber 14 enters the freezing air duct 40 from the freezing air return opening 43 under the forced action of the cold air supply fan 33, is cooled at the evaporator 32, and is circulated into the freezing chamber 14 from the freezing air outlet opening 42, thereby achieving the cooling of the freezing chamber 14.

The rear end of the refrigerating chamber 13 is provided with a refrigerating duct 50. The refrigerating air duct 50 comprises a refrigerating air duct cover plate 51, the refrigerating air duct cover plate 51 is positioned at the front end of the refrigerating air duct 50, and a refrigerating air port 52 and a refrigerating air return port 55 are arranged on the refrigerating air duct cover plate 51.

A refrigeration air inlet duct 53 and a refrigeration air return duct 54 are arranged between the refrigeration air duct 50 and the refrigeration air duct 40. Referring to fig. 2 and 3 in combination, solid arrows illustrate an air flow path in the refrigerator, when the cooling unit cools the refrigerator 13, hot air in the refrigerator 13 enters the refrigerator duct 50 through the refrigerator return air port 55 and the refrigerator return air duct 54 by the forced action of the cold air supply fan 33, is cooled at the evaporator 32, enters the refrigerator duct 50 along the refrigerator inlet air duct 53, and is circulated into the refrigerator 13 through the refrigerator return air port 52, thereby cooling the refrigerator 13.

The cold storage air inlet duct 53 is provided with an air door 531 for communicating the cold storage air inlet duct 53 or blocking the cold storage air inlet duct 53. Specifically, the refrigerating air inlet duct 53 is communicated when the damper 531 is opened, and the refrigerating air inlet duct 53 is not communicated when the damper 531 is closed.

When the refrigerating chamber 13 needs cooling, the system control damper 531 is opened; when the refrigerating compartment 13 does not require cooling, the system control damper 531 is closed.

The refrigerator further includes a condensing metal plate 61 and a refrigerating fan 62, both of which are provided in the refrigerating duct 50. Referring to fig. 2 and 3, when the cooling unit supplies cold air to the refrigerating compartment 13 through the refrigerating duct 50, the cold air of low temperature is blown toward the condensation metal plate 61, and the condensation metal plate 61 is at the lowest temperature, so that moisture in the air of the refrigerating compartment 13 is condensed on the condensation metal plate 61. The outside air is also introduced into the refrigerating chamber 13 when the user opens the refrigerator, and moisture of the outside air is condensed on the condensing metal plate 61.

Referring to fig. 2 and 4, when the cooling unit does not supply air to the refrigerating compartment 13, that is, in the case where the cooling unit is stopped or the damper 531 is closed, since the refrigerating air duct 50 communicates with the refrigerating compartment 13 by the refrigerating air port 52, when the refrigerating fan 62 is operated, air in the refrigerating air duct 50 and the refrigerating compartment 13 is circulated, thereby evaporating moisture condensed on the condensation metal plate 61 into the air, and increasing humidity to the refrigerating compartment 13.

The refrigerator of this application can realize the high humidity storage of cold storage chamber 13 through setting up condensation metal sheet 61 and refrigerating fan 62 in cold storage wind channel 50, compares in the prior art and sets up the high cost problem that special humidification device brought, and the structure of this application is simpler to the cost is very low, can be widely used on the cheap model.

Since the condensation metal plate 61 has a plate-like structure, it has a thin characteristic, so that it has little influence on the volume of the refrigerating chamber 13, and has an advantage of small occupied space.

Since only the condensing metal plate 61 and the refrigerating fan 62 need to be added in the refrigerating duct 50, the installation thereof is very convenient.

According to an embodiment of the present application, the condensation metal plate 61 may be made of a stainless steel material, i.e., the condensation metal plate 61 is specifically a stainless steel plate.

A cooling fan 62 may be provided above the condensing metal plate 61 to facilitate circulation of air in the cooling chamber 13.

The cold air inlet 56 is arranged on the cold air channel 50, and the cold air inlet 56 is connected with the cold air inlet channel 53. The condensing metal plate 61 may be located between the cool air inlet 56 and the refrigerating tuyere 52 in the front-rear direction of the refrigerating duct 50 such that cool air blown out from the cool air inlet 56 is blown onto the condensing metal plate 61 before flowing toward the refrigerating tuyere 52, thereby increasing the speed of condensing moisture at the condensing metal plate 61.

The condensing metal plate 61 is disposed adjacent to the refrigerating duct cover plate 51, which may make the structure of the refrigerating duct 50 more compact. Specifically, the condensing metal plate 61 and the refrigerating duct cover plate 51 are provided with a gap, and the presence of the gap provides a space for condensation of moisture on the condensing metal plate 61.

In some embodiments of the present application, the refrigerating duct cover 51 is provided with a plurality of refrigerating air vents 52, and referring to fig. 5, the shape of the refrigerating air vents 52 may be the same as that of a conventional air vent in a refrigerator, for example, the refrigerating air vents 52 are square.

During a cooling operation of the refrigerator, cool air blown into the refrigerating duct 50 by the cooling unit is blown into the refrigerating chamber 13 through the refrigerating air port 52, and during a humidifying operation, air in the refrigerating duct 50 and the refrigerating chamber 13 is communicated through the refrigerating air port 52. The plurality of refrigerating vents 52 may improve air flow efficiency, thereby improving cooling efficiency and humidification speed of the refrigerating compartment 13.

In other embodiments, referring to FIG. 6, the refrigerated air vents 52 may be micro-holes having an area much smaller than conventional air vents. The provision of the micro-holes prevents the articles in the refrigerating compartment 13 from entering the refrigerating air duct 50.

The shape of the micro-holes may be circular or polygonal such as diamond, which can improve the beauty of the cover plate 51 of the refrigerating duct while satisfying the ventilation effect.

The refrigerating wind gap 52 may be regularly covered with the refrigerating wind path cover 41 at intervals in the longitudinal and transverse directions to improve the air flow efficiency between the condensation metal plate 61 and the refrigerating chamber 13, thereby improving the humidifying efficiency.

In other embodiments, referring to fig. 7, the refrigerated air outlet 52 may include a refrigerated air outlet 521 and a refrigerated communication outlet 522. The refrigerating outlet 521 is provided corresponding to the refrigerating fan 62, and may be shaped as a conventional square outlet. And the refrigerating communication port 522 is in a microporous shape and is provided corresponding to the condensation metal plate 61.

When refrigerating the refrigerating chamber 13, most of the cold air flows into the refrigerating chamber 13 from the refrigerating outlet 521 at the refrigerating fan 62 due to the certain blocking effect of the condensation metal plate 61 against the cold air, and a small part of the cold air enters the refrigerating chamber 13 from the refrigerating communication port 522.

The refrigeration communication opening 522 mainly plays a role in a humidification stage, and improves air communication between the condensing metal plate 61 and the refrigerating chamber 13, thereby facilitating evaporation of the condensed water at the condensing metal plate 61.

In some embodiments of the present application, referring to fig. 8, the refrigerating return air port 55 may be provided at both left and right sides of the refrigerating compartment 13, and accordingly, the refrigerating return air duct 54 is located at the sides of the refrigerating compartment 13 and the freezing compartment 14, so that the distance between the refrigerating return air port 55 and the refrigerating return air port 52 may be extended.

If the refrigerating air return port 55 is located at the bottom of the refrigerating air duct cover plate 51 in a conventional manner, when the hot air in the refrigerating chamber 13 flows to the refrigerating air return port 55 during air return, part of the hot air contacts the condensation metal plate 61 through the refrigerating air port 52 around the refrigerating air return port 55, so that the bottom condensation effect of the condensation metal plate 61 is reduced.

In some embodiments of the present application, during the cooling operation, the cooling fan 62 may also be in an on state, and due to the effect of the cooling fan 62, the efficiency of blowing the cool air to the cooling chamber 13 may be increased, so as to increase the cooling speed of the cooling chamber 62.

The following describes the working state of the refrigerator of the present application:

when the temperatures of the refrigerating chamber 13 and the freezing chamber 14 are both proper, the compressor 31 and the cool air supply fan 33 are stopped, and the damper 531 is closed.

When the temperature of the refrigerating chamber 13 is proper and the temperature of the freezing chamber 14 is higher than a preset freezing temperature value, the compressor 31 is started, the damper 531 is closed, the cool air supply fan 33 is turned on, and cool air at the evaporator 32 is blown into the freezing chamber 14 through the freezing air outlet 42 and then returned to the evaporator 32 from the freezing air return 43.

When the temperature of the refrigerating chamber 13 is higher than the preset refrigerating temperature value, the compressor is started, the damper 531 is opened, the cool air supply fan 33 is turned on, and a portion of the cool air at the evaporator 32 circulates between the freezing chamber 14 and the freezing duct 40; the other part enters the refrigerating air channel 50 through the refrigerating air inlet channel 53, is blown into the refrigerating chamber 13 through the refrigerating air inlet 52, and then returns to the evaporator 32 through the refrigerating air return channel 55 and the refrigerating air return channel 54. In this process, the condensation metal plate 61 is cooled by the influence of the cool air, and the moisture in the refrigerating chamber 13 starts to condense on the condensation metal plate 61.

When the damper 531 is in the closed state, the refrigerating fan 62 is operated, and at this time, air between the refrigerating compartment 13 and the refrigerating duct 50 circulates, evaporating the moisture condensed on the condensation metal plate 61, and adding humidity to the refrigerating compartment 13.

The above description is given by taking a single-system refrigerator as an example, and the humidifying structure of the present application is also applicable to a dual-system refrigerator.

In the dual system structure, the cool air supply device may include two evaporators 32 for cooling the refrigerating compartment 13 and the freezing compartment 14, respectively. There is no air duct communication between the refrigerating chamber 13 and the freezing chamber 14. One of the evaporators 32 and the refrigerating fan 62 are provided in the refrigerating duct 50, and the cool air of the refrigerating compartment 13 circulates similarly to the freezing compartment 14.

The condensation metal plate 61 may be provided at the front side of the refrigerating duct 50; and the upper or lower end of the condensing metal plate 61 has a space from the inner wall of the refrigerating chamber 13, through which air circulation in the refrigerating chamber is achieved.

By arranging the condensation metal plate 61 and the refrigeration fan 62, cold air can be blown to the condensation metal plate 61 in the process of refrigerating the refrigerating chamber 13 by the cooling unit, so that the temperature of the condensation metal plate 61 is reduced to the minimum, and moisture in the air in the refrigerating chamber 13 is condensed on the condensation metal plate 61; in the humidification stage, the refrigerating fan 62 is operated to circulate the air in the refrigerating chamber, evaporate the water on the condensation metal plate 61, and increase the humidity in the refrigerating chamber 13.

The second concept of the present application is that the condensing metal plate 61 and the refrigerating fan 62 are disposed in the refrigerating duct 50 to realize high humidity storage of the refrigerating chamber 13, so that the present application has a simpler structure and low cost, and can be widely used in inexpensive models, compared to the high cost problem caused by the provision of a special humidifying device in the related art.

In the third concept of the present application, since the refrigerating wind gap 52 is fully covered with the refrigerating wind channel cover plate 51, the air circulation at the condensing metal plate 61 can be quickened in the humidifying stage, the evaporation efficiency of the moisture can be improved, and thus the humidifying speed can be improved.
