BACKGROUND

The present disclosure relates to refrigerators.


In general, refrigerators supply cold air generated from an evaporator to a storage space to maintain the freshness of various foods for a long period of time. The storage space of the refrigerator is divided into a refrigerating chamber which is maintained at approximately 3 degrees Celsius and thus stores foods in a refrigerated state and a freezing chamber where is maintained at approximately −20 degrees Celsius and thus stores foods in a frozen state.


The freezing chamber stores foods that must be maintained at the freezing temperatures or less, such as meat, fish, and frozen desserts, and the freezing chamber stores foods that must be maintained at the freezing temperatures or less, such as vegetables, fruits, and beverages.


A refrigerator uses a compressor, a condenser, an expander, and an evaporator to repeat the cooling cycle of compressing, condensing, expanding, and evaporating the refrigerant. The evaporator cools the surroundings by taking evaporation heat from the surroundings as the liquid refrigerant evaporates.


At this time, both the freezing chamber and the refrigerating chamber may be cooled by a single evaporator provided on the freezing chamber side, or the freezing chamber and the refrigerating chamber may each be provided with evaporators and cooled independently.


Meanwhile, in the refrigerating chamber, a separate storage space may be provided to maintain a lower temperature than other areas in the refrigerating chamber or for rapid cooling.

FIG. 1 is a front view illustrating a refrigerator according to one embodiment. FIG. 2 is a front view illustrating a state where the door of a refrigerator is opened according to one embodiment.


Referring to FIGS. 1 and 2, an outer appearance of the refrigerator 1 according to an embodiment of the present disclosure may be formed by a cabinet 10 forming storage spaces 11 and 12, and a door 20 that opens and closes the storage space of the cabinet 10.


For example, the cabinet 10 may form storage spaces 11 and 12 divided into upper and lower sections, and a refrigerating chamber 11 may be formed at the upper portion and a freezing chamber 12 may be formed at the lower portion. The refrigerating chamber 11 may be referred to as an upper storage space, and the freezing chamber 12 may be referred to as a lower storage space.


The door 20 may be configured to open and close the refrigerating chamber 11 and the freezing chamber 12, respectively. For example, the door 20 may be rotatably mounted on the cabinet 10, and the refrigerating chamber 11 and the freezing chamber 12 may be opened and closed by rotation, respectively. Of course, the door 20 may have a structure that opens and closes by pulling in and out.


The door 20 may include a refrigerating chamber door 21 that opens and closes the refrigerating chamber 11 and a freezing chamber door 22 that opens and closes the freezing chamber 12. The refrigerator door 21 may be referred to as an upper door and the freezing chamber door 22 may be referred to as a lower door.


Of course, in this embodiment, for convenience of explanation and understanding, the refrigerator 1 is described as an example in which the refrigerating chamber 11 is disposed at the top and the freezing chamber 12 is disposed at the bottom, but the present disclosure is not limited to a shape of the refrigerator and may be applied to all types of refrigerators equipped with doors.


Meanwhile, the door 20 forms an outer appearance of the front surface of the refrigerator 1 in a closed state, and may form the outer appearance of the refrigerator 1 seen from the front in a state where the refrigerator 1 is installed.



FIG. 3 is a schematic diagram illustrating the location of an evaporator in a refrigerator according to one embodiment.


Referring to FIG. 3, the refrigerator 1 according to one embodiment may include a plurality of evaporators. The plurality of evaporators may include a refrigerating chamber evaporator 31 that forms cold air supplied to the refrigerating chamber 11 and a freezing chamber evaporator 32 that forms cold air supplied to the freezing chamber.


For example, the refrigerating chamber evaporator 31 may be placed at the rear of the refrigerating chamber 11, and the freezing chamber evaporator 32 may be placed at the rear of the freezing chamber. Although not illustrated, the refrigerator 1 according to one embodiment is provided with one compressor and one condenser, respectively, and may provide refrigerant to the refrigerating chamber evaporator 31 and the freezing chamber evaporator 32, respectively. At this time, the compressor and condenser may be placed adjacent to the freezing chamber evaporator 32.


Hereinafter, the relationship between the refrigerating chamber, the evaporator, and the grill pan assembly will be described with reference to FIGS. 4 and 5.



FIG. 4 is a side schematic diagram illustrating the refrigerating chamber of a refrigerator according to one embodiment. FIG. 5 is a front view illustrating an evaporator and grill pan assembly of a refrigerator according to one embodiment


Referring to FIGS. 4 and 5, in the refrigerator 1 according to one embodiment, the refrigerating chamber 11 may include a plurality of refrigerating spaces maintaining different temperatures. As an example, the refrigerating chamber 11 may include a first storage part 111 and a second storage part 112 that maintains a lower temperature than the first storage part 111.


The first storage part 111 occupies a larger volume than the second storage part 112 and may be located above the second storage part 112. The second storage part 112 may be defined as the internal space of the cooling case 113 provided on the lower side inside the refrigerating chamber 11. The first storage part 111 may be defined as an external space of the cooling case 113 in the refrigerating chamber 11. In other words, the first storage part 111 and the second storage part 112 may be spatially separated by the cooling case 113 to be maintained at different temperatures.


Cold air formed in the refrigerating chamber evaporator 31 may be supplied to the first storage part 111 and the second storage part 112. Cold air supplied to the first storage part 111 may be supplied from the refrigerating chamber evaporator 31 to the first storage part 111 via the blowing fan assembly 43 and the grill pan 41. The grill pan 41 may be placed at the rear of the first storage part 111. Cold air supplied to the second storage part 112 may be supplied from the refrigerating chamber evaporator 31 to the second storage part 112 via the blowing fan assembly 43.


As an example, cold air supplied to the first storage part 111 may be inhaled in from the refrigerating chamber evaporator 31 by the blowing fan assembly 43 and moved upward. Cold air moving upward may be supplied to the first storage part 111 through the first pan discharge port 414 formed in the grill pan 41. Additionally, the cold air supplied to the second storage part 112 may be inhaled in from the refrigerating chamber evaporator 31 by the blowing fan assembly 43 and supplied to the second storage part 112.


In other words, the path through which cold air is supplied from the refrigerating chamber evaporator 31 may be shorter in the second storage part 112 than in the first storage part 111. As a result, cold air of a lower temperature than the cold air supplied to the first storage part 111 may be supplied to the second storage part 112.


Hereinafter, the detailed structure of the grill pan assembly 40 will be described with reference to FIGS. 6 to 8.



FIG. 6 is an exploded perspective view of a grill pan assembly of a refrigerator according to one embodiment. FIG. 7 is a cross-sectional view taken along line VII-VII of FIG. 5. FIG. 8 is a perspective view illustrating a path through which cold air is discharged from a refrigerator according to one embodiment.

The grill pan 41 assembly 40 according to an embodiment may include a grill pan 41 disposed at the rear of the refrigerating chamber and defining the rear wall of the refrigerating chamber, an insulation member 42 disposed at the rear of the grill pan 41, and a back cover 44 and a blowing fan assembly 43 disposed at the rear of the insulation member 42.


The grill pan 41 forms the rear surface of the refrigerating chamber and may be injection molded from a plastic material. The grill pan 41 may be formed in a rectangular plate shape.


The grill pan 41 may include a first plate part 411 disposed at the upper portion, a second plate part 412 disposed at the lower portion, and a third plate part 413 connecting a lower end of the first plate part 411 and an upper end of the second plate part 412.


The first plate part 411 may be disposed at the rear of the first storage part 111. The first plate part 411 may include a plurality of first pan discharge ports 414. The plurality of first pan discharge ports 414 may be passages through which cold air provided to the first storage part 111 is discharged.


The second plate part 412 may be disposed at the rear of the second storage part 112. The second plate part 412 may be located at the front of the first plate part 411. The second plate part 412 may include a second pan discharge port 415. The second pan discharge port 415 may be a passage through which cold air provided to the second storage part 112 is discharged. The second pan discharge port 415 may be located above the refrigerating chamber evaporator 31.


As will be described later, the opening area of the second pan discharge port 415 may be adjusted by the cold air control module 50.


The third plate part 413 may be located between the first plate part 411 and the second plate part 412. The third plate part 413 may be disposed at the rear of the first storage part 111. A blowing fan assembly 43 may be disposed at the rear of the third plate part 413. The blowing fan assembly 43 may be located above the evaporator 31 in the refrigerator.


Cold air formed in the refrigerating chamber evaporator 31 may be inhaled into the blowing fan assembly 43 through the space between the third plate part 413 and the blowing fan assembly 43. The insulation member 42 may not be disposed at the rear of the third plate part 413, but is not limited thereto.


The second plate part 412 may be disposed at the front of the first plate part 411. Accordingly, the third plate part 413 may be disposed to be inclined. For example, the lower end of the third plate part 413 may be located at the front of the upper end.


The first to third plate parts 413 may be formed integrally, but are not limited to this and may be formed separately and then joined to each other.


An insulation member 42 may be provided at the rear of the grill pan 41. The insulation member 42 prevents cold air provided from the refrigerating chamber evaporator 31 from being radiated and conducted into the refrigerating chamber, and at the same time may form a flow path part of the grill pan 41 that allows cold air to flow into the first storage part 111.


The insulation member 42 may be made of an EPS material that is easy to form and has excellent insulation performance. The insulation member 42 may be in close contact with the rear of the grill pan 41. The perimeter of the insulation member 42 may be in close contact with the inner surface of the grill pan 41 and the back cover 44.


The insulation member 42 may include a first insulation part 421 disposed at the rear of the first storage part 111 and a second insulation part 422 disposed at the rear of the second storage part 112. The first insulating part 421 may be located at the rear of the first plate part 411, and the second insulating part 422 may be located at the rear of the second plate part 412. The insulation member 42 may not be located at the rear of the third plate part 413. The heat insulation member 42 may not be disposed at the rear of the third plate part 413 because a blowing fan 431, which will be described later, inhales cold air from the front. In other words, the insulation member 42 may be arranged to non-overlap the blowing fan 431 in the front and rear direction. However, the insulation member 42 may also be located at the rear of the third plate part 413 without being limited thereto.


A first insulation member discharge port 423 that opens at a position corresponding to the first pan discharge port 414 of the first plate part 411 may be formed in the first insulation part 421. For example, the first heat insulation member discharge port 423 may be formed to have substantially the same shape as the first pan discharge port 414. Additionally, a grill pan 41 flow path through which cold air supplied to the first storage part 111 moves may be formed at the rear surface of the first insulation part 421. In other words, the cold air supplied to the first storage part 111 may pass through the grill pan 41 flow path, pass through the first insulation member discharge port 423 and the first pan discharge port 414, and be supplied to the first storage part 111.


A second insulation member discharge port 424 formed at a position corresponding to the second pan discharge port 415 of the second plate part 412 may be formed in the second insulation part 422. As an example, the second insulation member discharge port 424 may have a shape cut downward from the upper end of the second insulation part 422. The front end portion of the cover extension part 432b of the blowing fan assembly 43, which will be described later, may be coupled to the second insulation member discharge port 424. Cold air supplied to the second storage part 112 may pass through the second insulation member discharge port 424 and the second pan discharge port 415 and be supplied to the second storage part 112.


A blowing fan assembly 43 may be located at the rear of the insulation member 42. The blowing fan assembly 43 may inhale in cold air formed in the refrigerating chamber evaporator 31 and supply the cold air to the first storage part 111 and the second storage part 112. The blowing fan assembly 43 may be located above the refrigerating chamber evaporator 31.


The blowing fan assembly 43 may include a blowing fan 431 that inhales cold air through rotation and a blowing fan cover 432 that accommodates the blowing fan 431.


The blowing fan 431 may inhale in cold air from the front and discharge the cold air in a radial direction. The blowing fan cover 432 may guide the movement of cold air inhaled in and discharged from the blowing fan 431. In detail, cold air discharged in a radial direction from the blowing fan 431 may be guided according to the inner shape of the blowing fan cover 432 and discharged to the outside of the blowing fan assembly 43. An upper opening 436 may be formed on the upper side of the blowing fan cover 432 to discharge cold air into the flow path part of the grill pan 41, and a front opening 437 may be formed at the front to discharge cold air to the second storage part 112. The upper opening part 436 may be connected to the first storage part 111. The front opening part 437 may be connected to the second storage part 112.


The blowing fan 431 may be located at the rear of the third plate part 413. The blowing fan 431 may be located between the first plate part 411 and the second plate part 412. The blowing fan 431 may be located lower than the first pan discharge port 414. The blowing fan 431 may be located above the second pan discharge port 415.


The blowing fan cover 432 may be composed of a plurality of injection molded products. For example, the blowing fan cover 432 may include a front cover part 433 that covers the blowing fan 431 from the front and a rear cover part 434 that covers the blowing fan 431 from the rear. In this specification, the description is based on the blowing fan cover 432 consisting of the front cover part 433 and the rear cover part 434, but the blowing fan cover 432 is not limited thereto and may be formed as a single injection molded product or may be formed from a plurality of injection molded products of different structures.


The detailed structure of the blowing fan assembly 43 and the flow of cold air through the blowing fan assembly 43 will be described later with reference to FIGS. 9 to 12.



FIG. 9 is a front view illustrating a blowing fan assembly included in a refrigerator according to one embodiment. FIG. 10 is a side view illustrating a blowing fan assembly included in a refrigerator according to one embodiment. FIG. 11 is an exploded perspective view illustrating a blowing fan assembly included in a refrigerator according to one embodiment. FIG. 12 is a schematic diagram illustrating the flow of cold air passing through a blowing fan assembly in a refrigerator according to one embodiment.


Referring to FIGS. 9 to 12, the blowing fan cover 432 may include a cover main body part 432a that covers the blowing fan 431, and a cover extension part 432bextending from one side of the cover main body part 432a to be inclined downward toward the front. In this embodiment, the description is based on a structure in which the cover extension part 432b extends forward from the right side of the cover main body part 432a when viewed from the front of the refrigerator 1, but is not limited to this and the cover extension part (432b) may extend forward from the left side of the cover main body part 432a. If the portion to which the cover extension part 432b extends from the cover main body 432a is changed, the rotation direction of the blowing fan 431 may be changed accordingly.


The front cover part 433 may include a front main body part 433a defining the cover main body part 432a and a front extension part 433b defining the cover extension part 432b. The rear cover part 434 may include a rear body part 434a defining the cover main body part 432a and a rear extension part 434b defining the cover extension part 432b.


In other words, the cover main body part 432a may include a front main body part 433a and a rear main body part 434a. The cover extension part 432b may include a front extension part 433b and a rear extension part 434b.


A cold air inhale part 435 that opens to allow cold air to be inhaled in by the blowing fan 431 may be formed in the front main body part 433a. The cold air inhale part 435 may be open toward the front of the front main body part 433a.


An upper opening 436 through which cold air is supplied to the flow path part of the grill pan 41 may be formed on the upper side of the cover main body part 432a. As an example, the upper opening 436 may be defined by the upper end of the front main body part 433a and the upper end of the rear main body part 434a. The upper opening 436 may be formed entirely on the upper end of the cover main body part 432a, but is not limited to this and may be formed only on a portion of the upper end of the cover main body part 432a. The cover main body part 432a may form a first flow path 438 through which cold air supplied from the blowing fan cover 432 to the flow path part of the grill pan 41 moves. In other words, the first flow path 438 may be defined by the front main body part 433a and the rear body part 434a. Cold air flowing inside the blowing fan cover 432 may move in a direction away from the refrigerating chamber evaporator 31 through the first flow path 438.


The cover extension part 432b may extend toward the lower front. A portion of the cover extension part 432b connected to the cover main body part 432a may be located on the lower rear. The end portion of the cover extension part 432b where the front opening 437 is formed may be located at the lower front. The front extension part 433b may form one front and upper surface of the cover extension part 432b. The front end portion of the front extension part 433b may be coupled to the second insulation member discharge port 424. The rear extension part 434b may form one rear and lower surface of the cover extension part 432b.


As an example, the front opening 437 may be formed by opening the end portion of the front extension part 433b, but is not limited to this and may be formed by opening the end portion of the rear opening, or may be formed by coupling the end portion of the front opening 437 and the end portion of the rear opening. The cover extension part 432b may form a second flow path 439 through which cold air supplied from the blowing fan cover 432 to the second storage part 112 moves. In other words, the second flow path 439 may extend toward the front and lower side. The second flow path 439 may be defined by a front extension part 433b and a rear extension part 434b. Cold air flowing inside the blowing fan cover 432 may move in a direction closer to the refrigerating chamber evaporator 31 through the second flow path 439.


The first flow path 438 and the second flow path 439 may be located on opposite sides of each other with the blowing fan 431 in between. In other words, the blowing fan 431 may be disposed between the first flow path 438 and the second flow path 439.


The front opening 437 may be located at the front of the upper opening 436. Additionally, the front opening 437 may be located at the front of the cold air inhale part 435.


A portion of the cold air inhaled from the refrigerating chamber evaporator 31 by the blowing fan assembly 43 may pass through the first flow path 438 and the upper opening 436 formed in the cover main body part 432a to move the flow path part of the upper grill pan 41 and thus may be supplied to the first storage part 111 through the first insulation member discharge port 423 and the first pan discharge port 414. Meanwhile, another part of the cold air inhaled by the blowing fan assembly 43 from the refrigerating chamber evaporator 31 moves to the front opening 437 through the second flow path 439 formed in the cover extension part 432b, and thus may be supplied to the second storage part 112 through the second insulation member discharge port 424 and the second pan discharge port 415.


At this time, due to the difference in the movement path of cold air, the cold air supplied to the second storage part 112 may be lower in temperature than the cold air supplied to the first storage part 111. Accordingly, the second storage part 112 may be maintained at a lower temperature than the first storage part 111.
