In particular, in the present embodiment, the storage container 130 located at the lowermost position defines therein a storage compartment 131 and a cooling chamber located below the storage compartment 131.

Compared with the conventional refrigerator 100 with the cooling chamber located behind the storage chamber 131, in the refrigerator 100 of the embodiment, the cooling chamber does not occupy the space behind the storage chamber 131 any more, so that the depth of the storage chamber 131 is increased, and the storage volume of the storage chamber 131 is increased. Moreover, the height of the storage room 131 above the cooling room is raised, the bending degree of a user when the user puts articles into the storage room 131 for operation is reduced, the use experience of the user is improved, and the cooling room is particularly convenient for the old to use.

More particularly, in the present embodiment, the air duct 134 is disposed in the middle of the inner side of the rear wall of the storage inner container 130, and is communicated with the cooling chamber, and is used for conveying at least part of the air flow cooled by the evaporator 101 into the storage chamber 131.

In the conventional refrigerator 100, the width (lateral dimension) of the air duct is generally substantially the same as the width of the rear wall of the storage liner 130, and the air duct occupies an excessive space behind the storage compartment 131, so that the depth of the storage compartment 131 is reduced, and the storage volume of the storage drawer 133 disposed in the storage compartment 131 is affected. In this embodiment, the whole air supply duct 134 is located in the middle of the inner side of the rear wall of the storage liner 130, and the width (transverse dimension) of the air supply duct 134 is reduced, so that the space occupied by the air supply duct 134 is reduced, and the volume of the storage compartment 131 is ensured.

In one embodiment, as shown in fig. 2 and 3, a vertical beam 136 extending vertically is formed at the front side of the transverse middle portion of the storage liner 130, and the storage compartment 131 includes two storage spaces located at both sides of the vertical beam 136 in the transverse direction. A plurality of storage drawers 133 which are vertically distributed can be configured in each storage space, two first door bodies 132 which are transversely distributed are arranged on the front side of the storage liner 130, and the two first door bodies 132 correspond to the two storage spaces one by one so as to respectively open and close the corresponding storage spaces to form a split door.

In this embodiment, the air supply duct 134 is located right behind the vertical beam 136, that is, the width of the air supply duct 134 is substantially the same as the width of the vertical beam 136, and the section of the air supply duct 134 corresponding to the rear wall of the storage liner 130 may be vertically disposed at a position substantially in the middle of the inner side of the rear wall of the storage liner 130. Therefore, under the condition that the transverse size of the storage space is difficult to increase, the depth size of the storage space is increased by changing the position of the air supply duct 134, and the storage volume of the side-by-side combination refrigerator 100 is increased.

In some alternative embodiments, a vertical partition (not shown) extending vertically may be disposed at a transverse middle portion of the storage liner 130, the storage compartment 131 is divided into a left storage space and a right storage space by the vertical partition, and correspondingly, the front side of the storage liner 130 is also provided with a split door to open and close the corresponding storage space.

In view of the above two embodiments, since the storage compartment 131 is divided into two storage spaces, in order to facilitate the air supply uniformity of the two storage spaces, in a preferred embodiment, as shown in fig. 3, the diversion cover 1341 has two diversion air ducts, one of which extends transversely to the left and the right, and a left opening 134b communicated with the air supply opening is formed on the left end surface of the diversion air duct to guide the outlet air to the left and the right, so that the outlet air flows to the left storage space, and the other diversion air duct extends transversely to the right and the right, and a right opening 134a communicated with the air supply opening is formed on the right end surface of the diversion air duct to guide the outlet air to the right and the outlet air flows to the right storage space.

In the embodiment with the vertical partition plate, the left opening 134b and the right opening 134a of the design avoid the vertical partition plate located in front of the air supply duct 134, so that the influence of the vertical partition plate on the air supply is avoided, meanwhile, the air is respectively blown to the left storage space and the right storage space, and the air supply uniformity of the two storage spaces is ensured.

Correspondingly, the divergent air guiding duct flows the outlet air to the storage compartment 131 provided with the storage drawer 133 in the directions of two opposite corners in the transverse direction of the storage drawer 133.

The number of the blowing ports formed by the blowing duct 134 may be the same as the number of the storage drawers 133 disposed in the storage compartment 131 or the vertical direction of the storage drawers 133 disposed in one storage space, and accordingly, the number of the fairings 1341 is the same as the number of the storage drawers 133, and one fairings 1341 is provided obliquely above each storage drawer 133, so that the air flow is blown toward the storage drawer 133 from the upper opening of the storage drawer 133, increasing the smoothness of the air flow.

As shown in fig. 1, the cooling chamber may be defined by the cover 135 covering the bottom wall of the storage bladder 130 and the bottom wall of the storage bladder 130.

An air outlet communicated with an air inlet of the air supply duct 134 is formed at the rear end of the housing 135, so that air flow cooled by the evaporator 101 in the cooling chamber can enter the air supply duct 134, a front return air inlet 135a is formed in the front wall of the housing 135, and return air flow in the storage compartment 131 enters the cooling chamber through the front return air inlet 135a and is cooled by the evaporator 101.

The evaporator 101 may be disposed in the cooling chamber in a flat cubic shape, i.e., the long and wide sides of the evaporator 101 are parallel to the horizontal plane, the thickness side is perpendicular to the horizontal plane, and the thickness dimension is significantly smaller than the length dimension of the evaporator 101. By placing the evaporator 101 horizontally in the cooling chamber, the evaporator 101 is prevented from occupying more space, and the storage volume of the storage compartment 131 at the upper part of the cooling chamber is ensured.

As shown in fig. 1, the cabinet includes a refrigerating inner container 120, and the refrigerating inner container 120 is positioned right above a storage inner container 130 and defines a refrigerating chamber 121 therein. A refrigerating chamber door 122 is provided at the front side of the refrigerating inner container 120. The refrigerating chamber 121 may be partitioned into a plurality of storage spaces by a plurality of partitions 123 vertically spaced apart to facilitate classified storage of articles.

Further specifically, in some embodiments, as shown in fig. 6, the press cabin 102 is located at the rear lower part of the cooling chamber, so that the storage compartment 131 above the cooling chamber does not need to give way to the press cabin 102, and the storage compartment 131 can be a regular rectangular space, which is convenient for placing the large and difficult-to-partition articles, and solves the problem that the pain point of the large article cannot be placed in the lowermost storage compartment 131.

Further, as shown in fig. 8, a compressor 104, a radiator fan 106, and a condenser 105 are disposed in the compressor compartment 102 at intervals in the transverse direction.

In some embodiments, as shown in fig. 8, the plate segment 1162 of the rear wall of the nacelle corresponding to the compressor 104 is formed with at least one rear outlet vent 1162 a.

In fact, before the present invention, the general design idea of those skilled in the art is to provide a rear air inlet hole facing the condenser 105 and a rear air outlet hole 1162a facing the compressor 104 on the rear wall of the press chamber 102, and to complete the circulation of the heat dissipation airflow at the rear part of the press chamber 102; alternatively, ventilation holes are formed in the front wall and the rear wall of the press machine compartment 102, respectively, to form a heat dissipation circulation air passage in the front-rear direction. In the face of the problem of increasing the heat dissipation effect of the cabin, it is common for those skilled in the art to increase the number of rear air inlet holes and rear air outlet holes 1162a on the rear wall of the cabin 102 to enlarge the ventilation area, or to increase the heat exchange area of the condenser 105, for example, to use a U-shaped condenser with a larger heat exchange area.

The applicant of the present invention has creatively recognized that the heat exchange area of the condenser 105 and the ventilation area of the compressor compartment are not as large as possible, and in the conventional design scheme of increasing the heat exchange area of the condenser 105 and the ventilation area of the compressor compartment, the problem of uneven heat dissipation of the condenser 105 is brought about, which adversely affects the refrigeration system of the refrigerator 100. Therefore, the applicant of the present invention departs from the conventional design idea and creatively proposes a new scheme different from the conventional design, as shown in fig. 7 and 8, the bottom wall of the refrigerator 100 is limited to the bottom air inlet 110a close to the condenser and the bottom air outlet 110b close to the compressor 104, the refrigerator 100 completes the circulation of the heat dissipation airflow at the bottom thereof, the space between the refrigerator 100 and the supporting surface is fully utilized, the distance between the rear wall of the refrigerator 100 and the cabinet does not need to be increased, the space occupied by the refrigerator 100 is reduced, and meanwhile, the good heat dissipation of the compressor compartment is ensured, thereby fundamentally solving the pain point that the heat dissipation and the space occupation of the compressor compartment of the embedded refrigerator 100 cannot be balanced, and the present invention has a particularly important significance.

The heat dissipation fan 106 is configured to draw ambient air from the ambient environment at the bottom inlet 110a and force the air to flow through the condenser 105, then through the compressor 104, and then from the bottom outlet 110b to the ambient environment, thereby dissipating heat from the condenser and 105 to the compressor 104.

In the vapor compression refrigeration cycle, the surface temperature of the condenser 105 is generally lower than the surface temperature of the compressor 104, so in the above process, the outside air is first made to cool the condenser 105 and then the compressor 104.

Further in particular, in a preferred embodiment of the invention, the plate section 1161 of the back plate 116 (of the rear wall of the nacelle) facing the condenser 105 is a continuous plate surface, that is to say the plate section 1161 of the back plate 116 facing the condenser 105 is free of louvers.

The applicant of the present invention has creatively recognized that even on the premise of not increasing the heat exchange area of the condenser 105, the ventilation area of the reduced compressor compartment in the abnormal state can form a better heat dissipation airflow path, and a better heat dissipation effect can still be achieved.

The utility model discloses in the preferred scheme, the applicant breaks through conventional design, the back wall (backplate 116) of pressing the cabin and the plate section 1161 that condenser 105 corresponds design for continuous face, the heat dissipation air current that will get into in the pressing machine cabin seals in condenser 105 department for the ambient air who gets into by end air intake 110a concentrates on condenser 105 department more, the heat transfer homogeneity of each condensation zone of condenser 105 has been guaranteed, and be favorable to forming better heat dissipation airflow path, can reach better radiating effect equally.

Moreover, because the plate section 1161 of the back plate 116 facing the condenser 105 is a continuous plate surface and has no air inlet hole, it is avoided that in the conventional design, the hot air blown out from the press cabin is not cooled by the ambient air in time and enters the press cabin again due to the concentration of the outlet air and the inlet air at the rear part of the press cabin, and the heat exchange of the condenser 105 is adversely affected, thereby ensuring the heat exchange efficiency of the condenser 105.

In some embodiments, as shown in fig. 8, both lateral side walls of the nacelle are formed with one side vent 119a, the side vent 119a may be covered with a vent flap 108, and the vent flap 108 is formed with a grill-type vent aperture; the outer case of the refrigerator 100 includes two case side plates 111 in a lateral direction, the two case side plates 111 vertically extend to constitute two side walls of the refrigerator 100, and the two case side plates 111 respectively form one side opening 111a communicating with a corresponding side vent hole 119a so that a heat radiation airflow flows to the outside of the refrigerator 100. Therefore, the heat dissipation path is further increased, and the heat dissipation effect of the compressor cabin is ensured.

More particularly, the condenser 105 includes a first straight section 1051 extending laterally, a second straight section 1052 extending fore and aft, and a transition curve (not numbered) connecting the first straight section 1051 and the second straight section 1052, thereby forming an L-shaped condenser 105 with an appropriate heat exchange area. The plate segment 1161 of the rear wall (back plate 116) of the aforementioned nacelle corresponding to the condenser 105 is the plate segment 1161 of the back plate 116 facing the first straight segment 1051.

The ambient air flow entering from the side vent 119a directly exchanges heat with the second straight section 1052, and the ambient air entering from the bottom air inlet 110a directly exchanges heat with the first straight section 1051, so that the ambient air entering the cabin of the press is further concentrated at the condenser 105, and the uniformity of the overall heat dissipation of the condenser 105 is ensured.

Further specifically, as shown in fig. 7 and 8, the refrigerator 100 includes a bottom plate, a support plate 112, two side plates 119, and a vertically extending back plate 116, the support plate 112 constituting a bottom wall of the press compartment for carrying the compressor 104, the radiator fan 106, and the condenser 105, the two side plates 119 respectively constituting two lateral side walls of the press compartment, and the vertically extending back plate 116 constituting a rear wall of the press compartment.

Further specifically, the bottom plate includes a bottom horizontal section 113 located at the front side of the bottom and a bent section extending from the rear end of the bottom horizontal section 113 to the rear and upward, the bent section extends to the upper side of the supporting plate 112, and the compressor 104, the heat dissipation fan 106 and the condenser 105 are arranged on the supporting plate 112 at intervals in the transverse direction, and are located in the space defined by the supporting plate 112, the two side plates, the back plate 116 and the bent section.

The supporting plate 112 and the bottom horizontal section 113 together form a bottom wall of the refrigerator 100, and the supporting plate 112 and the bottom horizontal section 113 are spaced apart from each other to define a bottom opening by using a rear end of the bottom horizontal section 113 and a front end of the supporting plate 112, wherein the bent section has an inclined section 114 located above the bottom air inlet 110a and the bottom air outlet 110 b. The two side plates respectively extend upwards from two sides of the supporting plate 112 in the transverse direction to two sides of the bending section in the transverse direction so as to seal two sides of the press cabin in the transverse direction; the back plate 116 extends upward from the rear end of the support plate 112 to the rear end of the bent section.

Specifically, the bending section may include a vertical section 1131, the aforementioned inclined section 114, and a top horizontal section 115, wherein the vertical section 1131 extends upward from the rear end of the bottom horizontal section 113, the inclined section 114 extends upward from the upper end of the vertical section 1131 to the top of the supporting plate 112, and the top horizontal section 115 extends rearward from the rear end of the inclined section 114 to the back plate to shield the top of the compressor 104, the heat dissipation fan 106, and the condenser 105.

The front surface of the inclined section 114 may be formed with a protrusion 114a protruding upward, and the protrusion 114a is formed with a through hole 114a 1. As shown in fig. 4, the refrigerator 100 further includes a drain pipe 140 having one end connected to the drain port 130a and the other end extending through the penetration hole 114a1 into an evaporation pan (not numbered) provided in the compressor compartment 102 to drain the defrost water into the evaporation pan, the evaporation pan being generally located below the condenser 105, and the defrost water in the evaporation pan being evaporated by heat emitted from the condenser 105 and the compressor 104.

The refrigerator 100 further includes a partition 117, the partition 117 being disposed at the rear of the bent section, a front portion of the partition 117 being connected to a rear end of the bottom horizontal section 113, a rear portion of the partition being connected to a front end of the tray 112, and configured to divide the bottom opening into a bottom air inlet 110a and a bottom air outlet 110b arranged in a lateral direction.

As can be seen from the foregoing, the bottom air inlet 110a and the bottom air outlet 110b of the present embodiment are defined by the partition 117, the supporting plate 112, and the bottom horizontal section 113, so as to form the groove-shaped bottom air inlet 110a and the bottom air outlet 110b with larger opening sizes, increase the air inlet area and the air outlet area, reduce the air inlet resistance, make the airflow flow more smooth, and make the manufacturing process simpler, and make the overall stability of the cabin pressing chamber stronger.

In particular, the applicant of the present invention has innovatively recognized that the slope structure of the inclined section 114 can guide and rectify the intake airflow, so that the airflow entering from the bottom air inlet 110a flows to the condenser 105 more intensively, and the airflow is prevented from being too dispersed to pass through the condenser 105 more, thereby further ensuring the heat dissipation effect of the condenser 105; meanwhile, the slope of the inclined section 114 guides the outlet airflow of the bottom outlet 110b to the front side of the ground outlet, so that the outlet airflow flows out of the cabin more smoothly, thereby further improving the smoothness of airflow circulation.

More particularly, in the preferred embodiment, the angle of the angled section 114 is less than 45 ° from horizontal, and in this embodiment, the angled section 114 is more effective in directing and rectifying the airflow.

Further, unexpectedly, the inventors of the present application have innovatively recognized that the slope of the sloped section 114 provides a better suppression of airflow noise, and in prototype testing, the cabin noise of a press having the specially designed sloped section 114 was reduced by more than 0.65 db.

In addition, in the conventional refrigerator 100, the bottom of the refrigerator 100 generally has a plate-shaped bearing plate, the compressor 104 is disposed inside the plate-shaped bearing plate, and vibration generated during operation of the compressor 104 has a large influence on the bottom of the refrigerator body 100. In the embodiment, as mentioned above, the bottom of the refrigerator 100 is constructed into a three-dimensional structure by the bottom plate and the supporting plate 112 with special structures, so as to provide an independent three-dimensional space for the arrangement of the compressor 104, and the supporting plate 112 is used for carrying the compressor 104, thereby reducing the influence of the vibration of the compressor 104 on other components at the bottom of the refrigerator body 100. In addition, by designing the refrigerator 100 into the above-mentioned ingenious special structure, the structure of the bottom of the refrigerator 100 is compact and reasonable in layout, the overall volume of the refrigerator 100 is reduced, the space at the bottom of the refrigerator 100 is fully utilized, and the heat dissipation efficiency of the compressor 104 and the condenser 105 is ensured.

Further, particularly, the upper end of the condenser 105 is provided with a wind shielding member 1056, the wind shielding member 1056 may be a wind shielding sponge, which fills the space between the upper end of the condenser 105 and the bent section, that is, the wind shielding member 1056 covers the upper ends of the first straight section 1051, the second straight section 1052 and the transition curved section, and the upper end of the wind shielding member 1056 should abut against the bent section to seal the upper end of the condenser 105, so that part of the air entering the compressor compartment passes through the space between the upper end of the condenser 105 and the bent section without passing through the condenser 105, and thus the air entering the compressor compartment passes through the condenser 105 for heat exchange as much as possible, and further improving the heat dissipation effect of the condenser 105.

In some embodiments, the refrigerator 100 further includes a wind shielding strip 107 extending forward and backward, the wind shielding strip 107 is located between the bottom wind inlet 110a and the bottom wind outlet 110b, extends from the lower surface of the bottom horizontal section 113 to the lower surface of the supporting plate 112, and is connected to the lower end of the partition 117, so as to completely separate the bottom wind inlet 110a from the bottom wind outlet 110b by the wind shielding strip 107 and the partition 117, when the refrigerator 100 is placed on a supporting surface, the space between the bottom wall of the refrigerator 100 and the supporting surface is laterally divided, so as to allow the external air to enter the compressor compartment through the bottom wind inlet 110a located on one lateral side of the wind shielding strip 107 and to sequentially flow through the condenser 105 and the compressor 104 under the action of the heat dissipation fan 106, and finally flow out from the bottom wind outlet 110b located on the other lateral side of the wind shielding strip 107, so as to completely separate the bottom wind inlet 110a from the bottom wind outlet 110b, and, further ensuring the heat dissipation efficiency.
