For example, 'front' indicating the orientation refers to a side of the refrigerator facing a user, and 'transverse' refers to a direction parallel to the width direction of the refrigerator. This is only to facilitate the description of the present disclosure and to simplify the description, and is not intended to indicate or imply that the device or element referred to must have a particular orientation and be constructed and operated in a particular orientation, and therefore should not be construed as a limitation of the present disclosure.
FIG. 1 is a schematic front view of an embedded refrigerator according to an embodiment of the present disclosure. FIG. 2 is a schematic side sectional view of the embedded refrigerator shown in FIG. 1. The refrigerator may generally include a refrigerator body 10, and the refrigerator body 10 includes a housing, a liner and other accessories. The housing is an outer structure of the refrigerator and protects the entire refrigerator. In order to isolate the heat conduction with the outside, a heat insulating layer is additionally disposed between the housing and the liner of the refrigerator body 10, and the heat insulating layer is generally formed by a foaming process. The liner can be divided into one or more, and the liner can be divided into a refrigerating liner, a variable temperature liner, a freezing liner and the like according to the functions. The specific number and functions of liners can be configured according to the use requirements of the refrigerator. In the embodiment, the liner at least includes a bottom liner 101, and the bottom liner 101 can generally be the freezing liner.
The bottom liner 101 is the liner at the bottommost part of the refrigerator body 10, and defines a storage space 300 and a cooling chamber 100 located below the storage space 300. An evaporator 60 may be disposed in a middle front portion of the cooling chamber 100 slantingly upward from front to back along the depth direction of the refrigerator body. A bottom wall of the bottom liner 101 has a liner tilt portion, which is inclined upward from front to back, at a rear portion of the cooling chamber 100, and a tilt angle range is set to 30° to 40°, for example, the tilt angle can be set to be 33°, 35° or 38°, preferably 36.7°, thus providing a sufficient space for a compressor compartment 200. The storage space 300 can generally be used as a freezing space of the refrigerator.
The embodiment includes a refrigerating system. The refrigerating system includes a throttling element (not shown in the figures), the evaporator 60, a refrigeration fan 40, a compressor 20 and a condenser 30 connected to the compressor 20. Since the circulation structure and working principle of the refrigerating system itself are well known to those skilled in the art and are easy to implement, in order not to conceal and obscure the improvements of the present application, the refrigerating system itself will not be described in detail below.
As shown in FIG. 3, the compressor compartment 200 is formed at a rear of a bottom of the refrigerator body 10 in the embodiment. The compressor compartment 200 is defined by a bottom wall 220, a back plate 240 disposed at a rear end of the bottom wall 220, side plates 230 disposed at both ends of the bottom wall 220, and a compressor compartment cover plate 210 disposed above the bottom wall 220. The compressor compartment 200 is internally at least equipped with the compressor 20, the condenser 30 and a heat dissipation fan 50. The compressor 20 and the condenser 30 are disposed in the compressor compartment 200 at an interval in a transverse direction of the refrigerator body 10. In some embodiments, the condenser 30 can be a finned condenser, and fins of the condenser 30 are disposed from front to back along the depth direction of the refrigerator body 10, so that a heat dissipation air flow can pass through gaps between the fins directly, and the contact area with the heat dissipation air flow is therefore enlarged.
The bottom wall 220 of the compressor compartment 200 is provided with an air flow suction inlet 2220 in front of the condenser 30, and an air flow exhaust outlet 2230 in front of the compressor 20. Grilles are respectively formed at the air flow suction inlet 2220 and the air flow exhaust outlet 2230, that is, the air flow suction inlet 2220 and the air flow exhaust outlet 2230 are communicated with an outside of the refrigerator body 10 by means of ventilation holes formed among the grilles, so that foreign matters (such as small animals) are prevented from entering the refrigerator body 10 through the air flow suction inlet 2220 and the air flow exhaust outlet 2230. The air outside the refrigerator body 10 can enter the compressor compartment 200 from the air flow suction inlet 2220, take away heat from the condenser 30 by exchanging heat with the condenser 30, then enter a side where the compressor 20 is positioned in the compressor compartment 200 through the heat dissipation fan 50 to take away heat generated by the operation of the compressor 20, and is then discharged outside from the air flow exhaust outlet 2230 so as to achieve the purpose of dissipating heat from equipment in the compressor compartment 200.
The compressor compartment cover plate 210 of the embodiment includes an inclined front cover 211 and a top cover 212. The inclined front cover 211 is inclined upward from front to back in the depth direction of the refrigerator body 10 from front sides of the air flow suction inlet 2220 and the air flow exhaust outlet 2230. The top cover 212 extends horizontally rearward from a rear end of the inclined front cover 211 until being connected to the back plate 240. That is, the compressor compartment cover plate 210 is inclined to save an internal space of the refrigerator body 10 as much as possible and further increase the volume of the storage space 300 above the compressor compartment 200, thus improving the overall space utilization rate. The projection of the compressor compartment 200 on a horizontal plane is located behind the projection of the evaporator 60 on the horizontal plane, that is, the compressor compartment 200 and the evaporator 60 are placed in a staggered manner in a horizontal direction, which reduces the installation height of the evaporator 60 and increases the volume of the storage space 300.
The refrigerator of the embodiment includes the heat dissipation fan 50. The heat dissipation fan 50 is disposed between the compressor 20 and the condenser 30 to facilitate the formation of a heat dissipation air flow that enters from the air flow suction inlet 2220 and flows through the condenser 30 for heat exchange, and is then discharged to the air flow exhaust outlet 2230 through the compressor 20. The heat dissipation fan 50 may be an axial flow fan, and its rotation axis is parallel to the transverse direction of the refrigerator body 10. An air inlet side of the heat dissipation fan 50 faces the condenser 30, and an air outlet side thereof faces the compressor 20, and the heat dissipation fan 50 is used to promote the formation of the heat dissipation air flow that enters from the air flow suction inlet 2220 and flows through the condenser 30 for heat exchange, and is then discharged to the air flow exhaust outlet 2230 through the compressor 20. In some embodiments, a bracket and fan blades of the heat dissipation fan 50 can be assembled into an integral structure, and the outer periphery of the bracket of the fan is provided with an assembly structure to be directly fixed with a compartment wall of the compressor compartment 200. It is not necessary to set other brackets for fixing the fan in the compressor compartment 200, so that the structure in the compressor compartment 200 is simpler, the fixing effect is better, and the heat dissipation fan 50 operates more stably.
According to the refrigerator of the embodiment, an air shielding strip 280 is disposed on a lower surface of the refrigerator body 10. The air shielding strip 280 is disposed on the lower surface of the refrigerator body 10, and a middle portion of the air shielding strip 280 is a flexible section 283 that can be bent under a force, such that by bending the flexible section 283, the air shielding strip 280 is in an air shielding state in which the air shielding strip 280 divides a space between a lower part of the refrigerator body 10 and a ground supporting the refrigerator into an air inlet area communicated with the air flow suction inlet 2220 and an air outlet area communicated with the air flow exhaust outlet 2230. The flexible section 283 of the air shielding strip 280 can isolate the air flow suction inlet 2220 from the air flow exhaust outlet 2230 by bending, so as to prevent the heat dissipation air flow from circulating within a small range at the bottom of the refrigerator body 10, and further improve the heat dissipation efficiency.
As shown in FIG. 4-FIG. 8, the bottom wall 220 includes a compressor support plate 221, an air inlet plate 222, and an air outlet plate 223. The compressor support plate 221 is disposed at a rear portion of the bottom wall 220. The air inlet plate 222 extends forward from a front end of an area where the condenser 30 is located in the compressor support plate 221, and is provided with the air flow suction inlet 2220. The air outlet plate 223 extends forward from a front end of an area where the compressor 20 is located in the compressor support plate 221, and is provided with the air flow exhaust outlet 2230. When the flexible section 283 is not bent, the air shielding strip 280 extends linearly along a front end of the compressor support plate 221. That is, the air shielding strip 280 has two states. In an actual use process, the air shielding strip 280 is in the air shielding state (as shown in FIG. 4), and the air shielding strip 280 is bent to isolate the air flow suction inlet 2220 from the air flow exhaust outlet 2230, so as to avoid the circulation of the heat dissipation air flow in the small range at the bottom of the refrigerator body 10, and improve the heat dissipation efficiency; and during transportation, the air shielding strip 280 is in a received state (as shown in FIG. 5), and extends in a straight line along the front end of the compressor support plate 221, which is convenient to cooperate with a packaging box during transportation and handling, thus avoiding damage caused by collision.
The air shielding strip 280 includes a first shielding section 281, the flexible section 283, and a second shielding section 282. The first shielding section 281 is fixed between the front end of the compressor support plate 221 and the air inlet plate 222. One end of the flexible section 283 is connected to one end of the first shielding section 281 located in a middle portion of the refrigerator body 10. The second shielding section 282 is connected to the other end of the flexible section 283 and disposed in an area in front of the compressor 20, and changes the extension direction according to a bending degree of the flexible section 283. The first shielding section 281 is always fixed on the lower surface of the refrigerator body 10, and the second shielding section 282 can rotate on the lower surface along with the bending of the flexible section 283 to separate the air flow suction inlet 2220 from the air flow exhaust outlet 2230, so as to avoid the circulation of the heat dissipation air flow in the small range at the bottom of the refrigerator body 10 and improve the heat dissipation efficiency. In the received state, the second shielding section 282 is fixed between the front end of the compressor support plate 221 and the air outlet plate 223, and cooperates with the packaging box during transportation so as to avoid the damage caused by collision.
When the air shielding strip 280 is in the air shielding state, the flexible section 283 is bent into an arc shape, and the second shielding section 282 extends obliquely forward from a position between the air inlet plate 222 and the air outlet plate 223 with an inclination direction from back to the front biased towards a side where the compressor 20 is positioned. By cooperating the second shielding section 282 with the lower surface of the refrigerator body 10, the air outlet area is limited to the front side of the refrigerator body 10, so that the heat dissipation air flow can quickly leave the surrounding environment of the refrigerator, and the problem that the hotter heat dissipation air flow is scattered over an accommodation space of the embedded refrigerator after the heat exchange is completed, which causes the environment where the refrigerator is located to be hotter and increases the energy consumption of the refrigerator is therefore avoided. The air inlet area is restricted by the first shielding section 281 to be the other area around the refrigerator body 10than the air outlet area. The air enters the compressor compartment 200 through the air flow suction inlet 2220 communicated with the air inlet area, fully exchanges heat with the condenser 30, then enters the side where the compressor 20 is positioned through the heat dissipation fan 50 to take away the heat generated by the operation of the compressor 20, enters the air outlet area from the air flow exhaust outlet 2230, and then leaves the bottom of the refrigerator body 10.
A cross section of the air shielding strip 280 is L-shaped, where a horizontal side edge of the air shielding strip 280 is attached to the lower surface of the refrigerator body 10, a vertical side edge of the air shielding strip 280 is perpendicular to the lower surface of the refrigerator body 10, and the height of the vertical side edge matches the height from the lower surface of the refrigerator body 10 to the ground supporting the refrigerator, so as to fully separate the air flow suction inlet 2220 from the air flow exhaust outlet 2230; and therefore, the possibility that the heat dissipation air flow returns from the air flow exhaust outlet 2230 directly to the air inlet area through a gap between the air shielding strip 280 and the supporting ground is reduced, the circulation of the heat dissipation air flow within a small range at the bottom of the refrigerator body 10 is avoided, and the heat dissipation efficiency is improved.
The refrigerator of the embodiment further includes a partition 270. The partition 270 is disposed upward between the air inlet plate 222 and the air outlet plate 223 to separate an area in front of the compressor 20 and an area in front of the condenser 30 in the compressor compartment 200. The partition 270 includes a bottom plate 276, a first side plate 271 and a second side plate 272. The bottom plate 276 is positioned between the air inlet plate 222 and the air outlet plate 223. The first side plate 271 extends upward from an end, close to the air outlet plate 223, of the bottom plate 276 to isolate the area in front of the compressor 20. The second side plate 272 extends upward from an end, close to the air inlet plate 222, of the bottom plate 276 to isolate the area in front of the condenser 30. The partition 270 isolates the air flow suction inlet 2220 from the air flow exhaust outlet 2230, so that the heat dissipation air flow can only be discharged from the air flow exhaust outlet 2230 through the air flow suction inlet 2220, the condenser 30, the heat dissipation fan 50 and the compressor 20, which makes the heat dissipation more sufficient. A lower surface of the bottom plate 276 is provided with a claw 275 for fixing the second shielding section 282, so as to limit the position of the second shielding section 282 when the air shielding strip 280 is in the air shielding state.
A limit slot 274 adapted to the shape of a front end of the heat dissipation fan 50 is formed in a rear end wall of the first side plate 271 for accommodating a front portion of the heat dissipation fan 50. By connecting and fixing the partition 270 and the heat dissipation fan 50, all parts in the compressor compartment 200 are more closely connected and more integrated. Moreover, the above installation method using the limit slot 274 is convenient and fast, and simplifies the installation steps of the heat dissipation fan 50. In addition, the heat dissipation fan 50 extends from a rear portion of the first side plate 271 to a position between the compressor 20 and the condenser 30. The compressor compartment 200 is divided into a compressor side and a condenser side by the heat dissipation fan 50 and the partition 270. After fully exchanging heat with the condenser 30, the heat dissipation air flow can enter the compressor 20 side through the heat dissipation fan 50, and can be discharged out of the refrigerator body 10 from the air flow exhaust outlet 2230 only after taking away the heat generated during the operation of the compressor 20.
According to the embodiment, a drain pipe 110 of the embedded refrigerator extends from a drain outlet at a bottom of the liner above the compressor compartment cover plate 210 to an evaporating dish 250 through an area between the first side plate 271 and the second side plate 272. The arrangement of a reserved opening between the first side plate 271 and the second side plate 272 can effectively save an internal space of the compressor compartment 200, and further make an internal structure of the refrigerator body 10 more compact, thus increasing the overall space utilization rate of the refrigerator.
The embedded refrigerator of the embodiment is provided with an air deflector 273. The air deflector 273 extends from the first side plate 271 to a front of the compressor 20 to allow the heat dissipation air flow flowing through the compressor 20 to flow from a side away from the first side plate 271 to the air flow exhaust outlet 2230, and a projection of a tail end of the air deflector 273 in the depth direction of the refrigerator body 10 is aligned with a middle portion of the compressor 20. After the air deflector 273 is disposed in the compressor compartment 200, the heat dissipation space in the compressor compartment 200 will be further compressed for a fully embedded refrigerator, so an end point of the air deflector 273 should not be too long. A starting point of the air deflector 273 is disposed at a position where the heat dissipation fan 50 is located, so as to prevent the diffusion of heat dissipation; and the end point thereof is aligned with the middle portion of the compressor 20, which can guide all the heat dissipation air flow to the whole surface of the compressor 20 to maximize the heat dissipation of the compressor 20, thus preventing the air volume loss when the heat dissipation air flow moves from an initial point to an apex , and further effectively lowering the temperature of the compressor 20. In addition, due to the arrangement of the air deflector 273, the air volume swirl is reduced, the temperature of the condenser 30 is lowered, and effective energy conservation is achieved.
According to the embodiment, the condenser 30 is cuboid in an overall shape, and is installed to allow its radiating fins to extend along the depth direction of the refrigerator body 10, so that the air entering from the air flow suction inlet 2220 flows along passages between the radiating fins for heat exchange, and then flows to the heat dissipation fan 50 from an interval between the condenser 30 and the back plate 240. The radiating fins are in parallel arrangement along the depth direction. After entering from the air flow suction inlet 2220, the air can smoothly contact and exchange heat with all the fins through gaps between the radiating fins, thus greatly enhancing the heat dissipation effect. In some embodiments, the condenser 30 can be tilted upward from front to back along the depth direction of the refrigerator body 10, which can effectively utilize the air inhaled in the air flow suction inlet 2220 to increase the full contact area between the air and the condenser 30 and enhance the heat dissipation effect. In some other embodiments, the condenser 30 may also use a micro-channel heat exchanger.
According to the embedded refrigerator of the embodiment, an air guide assembly 290 can also be disposed in the compressor compartment 200. The air guide assembly 290 is disposed at an outer periphery of the condenser 30, and is configured to guide the air inhaled from the air flow suction inlet 2220 to completely cross the condenser 30, so as to avoid the air flow escaping from the outer periphery of the condenser 30, and allow the air flow to flow to the heat dissipation fan 50 only from the interval between the condenser 30 and the back plate 240. The heat dissipation air flow can be enabled to fully contact the condenser 30, so that the heat dissipation performance is improved.
According to the embedded refrigerator of the embodiment, the air shielding strip 280 is disposed on the lower surface of the refrigerator body 10, the air shielding strip 280 has the flexible section 283, and the air flow suction inlet 2220 can be isolated from the air flow exhaust outlet 2230 by bending the flexible section 283, so that the circulation of the heat dissipation air flow within the small range at the bottom of the refrigerator body 10 is avoided, and the heat dissipation efficiency is increased.
Further, the air shielding strip 280 extends linearly along the front end of the compressor support plate 221 when the flexible section 283 is not bent, which is convenient to cooperate with the packaging box during transportation, thus reducing the risk of collision damage.
