Referring to fig. 1, fig. 1 is a schematic view of a refrigerator 1 according to an embodiment of the present invention. The invention provides a refrigerator 1, wherein the refrigerator 1 is suitable for being used singly and embedded in a cabinet. In general, the refrigerator 1 may include a cabinet 10 and a door 60.

The cabinet 10 may include a housing 11 and at least one liner 13, the housing 11 being located at the outermost side of the overall refrigerator 1 to protect the overall refrigerator 1. The plurality of inner containers 13 are wrapped by the outer case 11, and a space between the plurality of inner containers 13 and the outer case 11 is filled with a heat insulating material (forming a heat insulating layer 12) to reduce heat dissipation of the inner containers 13 to the outside. Each liner 13 may define a forwardly open storage space, and the storage spaces may be configured as a refrigerator compartment, freezer compartment, temperature change compartment, etc., the number and function of the specific storage spaces may be configured according to the pre-requirements.

The number of the door bodies 60 can be the same as that of the inner containers 13, namely, each storage compartment of the inner container 13 which is opened forwards can be opened and closed by the corresponding door body 60. The door 60 is movably provided in front of the case 10, for example, the door 60 may be provided at one side of the front of the case 10 in a hinged manner, and the storage space may be opened and closed in a pivotal manner.

Referring to fig. 2, fig. 2 is a schematic view of a refrigerating system 20 in the refrigerator 1 according to an embodiment of the present invention. In some embodiments, the refrigerator 1 may further include a refrigeration system 20 for providing cold to the storage compartments. The refrigeration system 20 may also include a compressor 21, a condenser 22, a dew point removing tube 23, a throttle device 24, an evaporator 25, and the like in the refrigerant flow path.

The compressor 21 is used as power of the refrigerating system 20, the bottom of the rear side of the cabinet 10 is provided with a compressor compartment 15, and the compressor 21 may be disposed in the compressor compartment 15 (as shown in fig. 1). The compressor 21 increases the pressure and temperature of the refrigerant vapor by compression, creating a condition for transferring heat of the refrigerant vapor to an external environment medium, i.e., compressing the low-temperature low-pressure refrigerant vapor to a high-temperature high-pressure state so that the refrigerant vapor can be condensed using normal-temperature air or water as a cooling medium.

The condenser 22 is a heat exchange device that takes heat from the high-temperature and high-pressure refrigerant vapor from the compressor 21 by using the environment, and cools and condenses the high-temperature and high-pressure refrigerant vapor into a refrigerant liquid at a high pressure and a normal temperature.

The dew removing pipe 23 is connected to the outlet of the condenser 22, and since the refrigerant at the outlet of the condenser 22 is at a normal temperature and the temperature of the refrigerant is high with respect to the storage compartment, the refrigerant can heat the surrounding members when passing through the dew removing pipe 23, and frost formation is avoided. Specifically, the dew removing tube 23 may be provided at a position of the cabinet 10 where heating dew removal is required, for example, in a center sill of the refrigerator 1 or the like.

A throttling device 24 (which may be a capillary tube) may be connected in series to the outlet of the condenser 22 to reduce the pressure and temperature of the refrigerant liquid, so as to change the refrigerant liquid discharged from the condenser 22 at a high pressure and a normal temperature into a low temperature and low pressure refrigerant, and then discharged into the evaporator 25 for phase change heat absorption.

An evaporator 25 may be provided in the cabinet 10 to directly or indirectly supply cold to the storage compartment of the refrigerator 1. For example, in the compression-type direct-cooling refrigerator 1, the evaporator 25 may be provided outside or inside the rear wall surface of the liner 13. In the compressed air-cooled refrigerator 1, an evaporator chamber is further arranged in the refrigerator body 10, the evaporator chamber is communicated with the storage compartment through an air path system, an evaporator 25 is arranged in the evaporator chamber, and a fan is arranged at an outlet of the evaporator chamber so as to circularly refrigerate the storage compartment.

Referring to fig. 1 and 3, fig. 3 is a top view of a refrigerator 1 according to an embodiment of the present invention. In some embodiments, the condenser 22 is not disposed in the press cabin 15, but disposed at the top of the box 10, so that the condenser 22 and the compressor 21 are disposed in different spaces to dissipate heat respectively, which can improve the heat dissipation efficiency of the two and further improve the refrigerating effect of the refrigerating system 20.

In addition, the condenser 22 is arranged at the top of the box body 10, so that the load of the cabin 15 can be reduced, the original condenser 22 can be eliminated from occupying the space of the cabin 15, and the space of the storage cabin can be enlarged. For example, the press cabin 15 may be designed to occupy only one lateral side of the housing 10, thus freeing up space to the liner on the other lateral side (i.e., the liner may extend more rearward on that side), so that the expanded space may be used to place the evaporator, resulting in a more compact structure and higher space utilization.

Specifically, a compressor 21 disposed in the press cabin 15 is connected to a condenser 22 disposed at the top of the case 10 through a refrigerant pipe. The refrigerant pipeline can also pass through the heat preservation layer 12 in the box body 10 to play a role in hiding the refrigerant pipeline.

Referring to fig. 3, in some embodiments, the refrigerator 1 may further include a heat radiating pipe 30 disposed at the top of the cabinet 10, surrounding the condenser 22, and forming a heat radiating passage 303 opened forward, the heat radiating pipe 30 further having at least one heat radiating air inlet 301 and one heat radiating air outlet 302, each heat radiating air inlet 301 being located adjacent to a front side edge of the cabinet 10, the heat radiating air outlet 302 being located at a rear side of the condenser 22, the heat radiating pipe 30 being configured to introduce air of a front space of the cabinet 10 into the inside thereof and blow the air forward from the rear toward the condenser 22, and finally discharging the air forward from the heat radiating passage 303 out of the cabinet 10.

Since the rear space and the left and right sides of the refrigerator 1 are shielded by the cabinet when the refrigerator 1 is inserted into the cabinet, heat dissipation is not good in both backward and sideways directions.

In the present embodiment, since the heat radiation air flow inlet 301 of the heat radiation pipe 30 is adjacent to the front edge of the cabinet 10 and the heat radiation air flow outlet 302 is at the rear side of the condenser 22, the heat radiation pipe 30 can suck air of the front space of the refrigerator 1 therein and guide the sucked air to the rear side of the condenser 22, and blow the sucked air from the rear to the front toward the condenser 22 to exchange heat with the condenser 22. That is, the embodiment realizes that the air inlet is formed on the front side of the top of the box body 10, the air quantity is larger, and the heat exchange effect is higher.

In addition, since the radiating pipe 30 surrounds the condenser 22 to form the radiating passage 303 opened forward, air after heat exchange with the condenser 22 can be directly discharged into the radiating passage 303 and then discharged forward from the radiating passage 303 to the front side of the cabinet 10 to achieve front air-out, thereby forming a cycle.

Therefore, in the refrigerator 1 of the embodiment, the heat dissipating tube 30 not only can guide the air flow in the front space of the box 10 to the condenser 22 at the top of the box 10 to realize front air intake, but also surrounds the condenser 22 by the tube shape of the heat dissipating tube 30, thereby forming a heat dissipating channel 303 which is opened forwards, preventing the air flow after heat exchange from being mixed and fleed at the top of the box 10, realizing front air outlet guiding, forming circulating air flow, fully utilizing the open space in front of the box 10, improving the air intake of the heat dissipating air flow, and optimizing the heat dissipating efficiency of the condenser 22.

Referring to fig. 3, in some embodiments, the radiating pipe 30 may further include a first pipe section 310, a second pipe section 320, and a third pipe section 330, the first pipe section 310 being located at a lateral first side of the case 10 and extending integrally from front to rear, and having a front end as one radiating airflow inlet 301. The first end of the second tube section 320 is formed at the rear end of the first tube section 310 and extends from the lateral first side to the lateral second side of the case 10, and the heat dissipating airflow outlet 302 is provided at the front wall of the second tube section 320. The third tube section 330 is located on a lateral second side of the housing 10, has a rear end formed at the second end of the second tube section 320 and extends integrally from rear to front, and has a front end serving as a heat dissipating airflow inlet 301.

Since the radiating pipe 30 surrounds the condenser 22 to form the radiating passage 303 opened forward, the first pipe section 310 and the third pipe section 330 extend on the first lateral side and the second lateral side of the condenser 22, the second pipe section 320 extends behind the condenser 22, and the three together constitute the radiating passage 303 surrounding the condenser 22, and the opposite front side of the second pipe section 320 serves as an opening of the radiating passage 303.

In this embodiment, the number of the heat dissipating airflow inlets 301 is two, the two heat dissipating airflow inlets 301 are respectively disposed at the front ends of the first pipe section 310 and the third pipe section 330, and the first pipe section 310 and the third pipe section 330 are respectively disposed at the first side and the second side of the transverse line of the case 10, that is, the heat dissipating pipe 30 can suck air from the front of the first side and the second side of the top of the case 10 at the same time, then gather in the second pipe section 320, and finally be discharged from the heat dissipating airflow outlet 302 to the condenser 22.

Further, the first pipe section 310 and the third pipe section 330 extend in the front-rear direction as a whole, which means that the first pipe section 310 and the third pipe section 330 may extend strictly in the front-rear direction (as shown in fig. 3) or may extend obliquely in the left-right direction while extending in the front-rear direction.

Referring to fig. 4, fig. 4 is a top view of a refrigerator 1 according to another embodiment of the present invention. For example, in some particular embodiments, the first tube segment 310 is disposed rearwardly from its forward end and inclined to the lateral second side, and the third tube segment 330 is disposed rearwardly from its forward end and inclined to the lateral first side.

That is, the front end of the first pipe section 310 is closer to the first lateral side, the front end of the third pipe section 330 is closer to the second lateral side, and the heat dissipation channel 303 formed in this way is gradually expanded from back to front, so that the heat dissipation channel 303 in the gradually expanded shape can reduce the flow rate of the heat dissipation air flow discharged from back to front, and further the air outlet at the opening of the heat dissipation channel 303 is gentle, the air pressure is not too low, and the influence on the air inlet of the heat dissipation air flow inlet 301 of the first pipe section 310 and the air inlet 301 of the third pipe section 330 is small.

Referring to fig. 5 and 6, fig. 5 is a schematic view of a structure of a top of a cabinet 10 in a refrigerator 1 according to an embodiment of the present invention, and fig. 6 is a schematic view of a condenser 22 in the refrigerator 1 according to an embodiment of the present invention. In some embodiments, the condenser 22 is flat and horizontally disposed on top of the box 10, and forms an air intake gap 14 with the top surface of the box 10, and a plurality of vertically penetrating heat dissipation micro channels 220 are defined in the condenser 22. The refrigerator 1 further includes a heat dissipation fan 40, the heat dissipation fan 40 is disposed at the condenser 22, and the heat dissipation fan 40 can promote air in the front space of the box 10 to enter the heat dissipation tube 30 through the heat dissipation airflow inlet 301, and sequentially enter the heat dissipation micro-channel 220 through the heat dissipation airflow outlet 302 and the air inlet gap 14 to exchange heat with the condenser 22.

The condenser 22 is flat and horizontally arranged at the top of the box body 10, so that the height of the condenser 22 protruding out of the top of the box body 10 can be reduced as much as possible, the overall height of the refrigerator 1 is reduced, and interference with a cabinet is avoided.

The bottom surface of the condenser 22 is spaced from the top surface of the cabinet 10, forming an air intake gap 14 therebetween. Since the vertically penetrating heat dissipation micro-channel 220 is defined in the condenser 22, after the heat dissipation fan 40 is started, air in the front of the box 10 can be caused to enter the heat dissipation tube 30 through the two heat dissipation air inlets 301, then is discharged to the air inlet gap 14 below the condenser 22 from the heat dissipation air outlets 302, and then passes through the heat dissipation micro-channel 220 from bottom to top in the air inlet gap 14, so that heat exchange with the condenser 22 is realized, and the air after heat exchange is directly discharged into the heat dissipation channel 303 and finally is discharged forward to the front space of the box 10, so that circulation is formed.

Referring to fig. 5 and 6, in some particular embodiments, the condenser 22 may also be a microchannel condenser 22. The condenser 22 may further include a plurality of flat tubes 221 and a plurality of fins 222, wherein the plurality of flat tubes 221 are arranged in parallel at intervals and sequentially connected, and a wider surface of each flat tube 221 is arranged vertically, each fin 222 is arranged vertically between two flat tubes 221, and a heat dissipation micro-channel 220 is formed between every two fins 222.

The flat tubes 221 may be flat, and one wider surface of each flat tube 221 is vertically disposed, and the flat tubes 221 may be disposed at intervals in the front-rear direction or may be disposed at intervals in the lateral direction. A plurality of vertical fins 222 are formed between every two adjacent flat tubes 221, and a heat dissipation micro-channel 220 which is vertically arranged is formed between every two adjacent fins 222. The fins 222 conduct heat from the flat tubes 221 to the fins 222, so that when the air flows through the heat dissipation micro-channels 220, the air flows and the fins 222 exchange heat in a convection manner to take away the heat.

Since the air inlet gap 14 is formed between the condenser 22 and the top surface of the case 10, the air flow discharged from the heat dissipating air flow outlet 302 can first enter the air inlet gap 14, and then pass through the heat dissipating micro-channels 220 from bottom to top to exchange heat with the fins 222 and the flat tubes 221, so that the heat of the condenser 22 is timely taken away.

Referring to fig. 5, in some embodiments, the heat dissipation fan 40 is a centrifugal fan, disposed above the flat tube 221, and an axial air inlet side of the heat dissipation fan 40 is disposed opposite to the heat dissipation micro-channels 220 to suck air from the heat dissipation micro-channels 220 and discharge the air to the heat dissipation channels 303 in a radial direction.

When the centrifugal fan is started, air in the front of the box 10 is caused to enter the radiating pipe 30 through the two radiating airflow inlets 301, then is discharged to the air inlet gap 14 below the condenser 22 from the radiating airflow outlets 302, then passes through the radiating micro-channel 220 from bottom to top in the air inlet gap 14 to exchange heat with the condenser 22, and the airflow after heat exchange is discharged into the radiating channel 303 along the radial direction thereof and finally is discharged forward to the front space of the box 10 to form circulation.

Referring to fig. 5, further, the heat dissipation fan 40 is located at the rear side of the flat tube 221. The condenser 22 further includes a plurality of guide plates 223, and the plurality of guide plates 223 are formed above the flat tubes 221 at intervals and extend forward from the front end of the heat radiation fan 40 to guide the air flow discharged in the radial direction of the heat radiation fan 40 forward.

That is, the plurality of guide plates 223 correspond to the scroll case of the centrifugal fan to guide the air flow to be discharged forward from the gap between the adjacent two guide plates 223, further improving the circulation of the circulating air flow and the heat exchange efficiency.

Referring to fig. 5, in some embodiments, since the plurality of baffles 223 extend from back to front and are formed above the flat tube 221, when the flat tube 221 is also configured to extend back and forth, the plurality of baffles 223 can be formed in a one-to-one correspondence with the plurality of flat tubes 221, thereby simplifying the forming process.

In addition, since the deflector 223 is formed on the flat tube 221, the deflector 223 can realize forward flow guiding on one hand, and can absorb heat on the flat tube 221 on the other hand, so that the air flow flowing through the deflector 223 can be exactly utilized to perform secondary heat exchange, the heat exchange path is prolonged, and the heat exchange efficiency is further improved.

In addition, since the guide plate 223 is disposed in front of the centrifugal fan for guiding the flow, the height of the guide plate can be slightly higher than that of the centrifugal fan, so that the centrifugal fan cannot protrude out of the guide plate 223, and the function of protecting the centrifugal fan is achieved.

Referring to fig. 7, fig. 7 is a schematic view showing a structure of a top of a cabinet 10 in a refrigerator 1 according to another embodiment of the present invention. In some embodiments, the heat dissipation fan 40 may also be a cross flow fan, which is disposed above the condenser 22 in a lateral direction and located at a front side of the flat tube 221 to suck air from the heat dissipation micro-channels 220 and discharge the air forward to the heat dissipation channels 303.

The cross-flow fan mainly comprises an impeller, an air duct and a motor. The impeller is cylindrical, can be arranged transversely, and the air duct is wrapped around the impeller and is provided with an air inlet and an air outlet which are opposite to the impeller. In this embodiment, since the cross flow fan is disposed above the flat tube 221 and needs to intake air upward and exhaust air forward, the air intake may face the condenser 22, and the air outlet may be opened forward.

When the cross flow fan is started, air in the front of the box body 10 is caused to enter the radiating pipe 30 through the two radiating airflow inlets 301, then is discharged to the air inlet gap 14 below the condenser 22 from the radiating airflow outlet 302, then passes through the radiating micro-channel 220 from bottom to top in the air inlet gap 14, achieves heat exchange with the condenser 22, the air after heat exchange is sucked into the air inlet of the cross flow fan, is sent out forwards from the air outlet after changing the direction of the impeller, and finally is discharged forwards out of the top of the box body 10 to form circulation.

Referring to fig. 8, fig. 8 is an exploded view of a medium pressure compartment 15 in the refrigerator 1 according to an embodiment of the present invention. In some embodiments, the press cabin 15 has a bottom steel 150, two side plates 152 disposed on both sides of the bottom steel 150, a back plate 154 disposed on the back side of the bottom steel 150, and a cover plate 155 disposed over the bottom steel 150. The bottom steel 150 is provided with a bottom air inlet portion 150a and a bottom air outlet portion 150b in a lateral direction, and the compressor 21 is located between the bottom air inlet portion 150a and the bottom air outlet portion 150 b.

Because the bottom space is arranged between the bottom of the box body 10 and the ground under the support of the bottom foot, the bottom steel 150 of the press cabin 15 is transversely provided with the bottom air inlet part 150a and the bottom air outlet part 150b, and the compressor 21 is positioned between the bottom air inlet part 150a and the bottom air outlet part 150b, the heat dissipation air flow of the press cabin 15 enters the press cabin 15 from the bottom space through the bottom air inlet part 150a to exchange heat with the compressor 21, and then is downwards discharged to the bottom space from the bottom air outlet part 150 b. In addition, a cooling fan 50 may be disposed within the press cabin 15 to facilitate air from the bottom space into the press cabin 15 from the bottom inlet 150a and out the bottom outlet 150b to the bottom space.

When the refrigerator 1 is embedded into a cabinet for use, the circulation between the bottom space of the refrigerator 1 and the surrounding environment is better than that of the side part of the refrigerator 1, so that the ventilation efficiency of the heat dissipation air flow can be effectively improved towards the bottom, the heat dissipation effect of the press cabin 15 is improved, and the use environment of the embedded refrigerator 1 is more facilitated.

The two side plates 152 serve as the left and right side walls of the press cabin 15, respectively. Since the air intake of the bottom air intake portion 150a may already satisfy the ventilation of the compressor compartment 15, the side air intake on the side plate 152 adjacent to the bottom air intake portion 150a may be eliminated. Whether the refrigerator 1 is used independently or is embedded, the bottom air inlet mode can be adopted to ventilate the press cabin 15.

In addition, the refrigerator 1 can also keep the side air outlet mode, namely keep the side air outlet 152a on the side plate 152 adjacent to the bottom air outlet portion 150 b. Thus, when the refrigerator 1 is used independently, air in front of the refrigerator 1 can enter the cabin 15 through the bottom air inlet portion 150a, and then is simultaneously discharged outwards through the bottom air outlet portion 150b and the side air outlet 152a, so that the air outlet efficiency can be improved, and discomfort caused by a large amount of hot air flowing forwards on the foot surface of a user can be avoided. In the embedded use, the side air outlet 152a may be blocked, so that most of the heat dissipation air flow is discharged from the bottom air outlet portion 150b to the bottom space, and the heat dissipation effect can be ensured.

Furthermore, the back plate 154 serves as a rear wall of the press cabin 15. Therefore, in order to avoid the air leakage phenomenon, the heat dissipation air flow is prevented from being discharged out of the pressure cabin 15 without passing through the compressor 21, and no air outlet is arranged on the back plate 154.

Further, the bottom air inlet portion 150a may include a plurality of bottom air inlet holes formed on the bottom steel 150, each of the bottom air inlet holes has a strip shape, and the plurality of bottom air inlet holes are arranged in an array manner. The bottom air outlet portion 150b may include a plurality of bottom air outlet holes formed on the bottom steel 150, each of the bottom air outlet holes is in a strip shape, and the plurality of bottom air outlet holes are arranged in an array manner. Thus, on the basis of ensuring that the bottom air inlet portion 150a meets ventilation requirements, the aesthetic property of the bottom air inlet portion 150a is improved.

Of course, the shapes and arrangement of the bottom air inlet holes and the bottom air outlet holes on the bottom air inlet portion 150a and the bottom air outlet portion 150b may be other manners. For example, in other embodiments, portions of the sheet sections of the bottom steel 150 may also be formed of wire mesh such that voids in the wire mesh act as bottom air inlet and bottom air outlet.

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.
