A plurality of storage containers 1311 are disposed in the freezing chamber 131 in an up-down distribution, and as shown in fig. 1, three storage containers 1311 are disposed in an up-down distribution.

As those skilled in the art can appreciate, the refrigerator 100 of the present embodiment may further include an evaporator 150, a blower fan 102, a compressor 104, a condenser 105, a throttling element (not shown), and the like. The evaporator 150 is located in the cooling chamber 133, and is connected to the compressor 104, the condenser 105, and the throttle element via refrigerant lines to form a refrigeration cycle, and is cooled when the compressor 104 is started to cool air flowing therethrough to form a cooling air flow. The blower 102 may be a centrifugal fan, a cross flow fan, or an axial flow fan.

In particular, in the present embodiment, the blower 102 is positioned laterally to the evaporator 150 and downstream of the evaporator 150 in the airflow path and is configured to urge at least a portion of the cooling airflow toward the at least one storage compartment.

In the refrigerator 100 of the present embodiment, the blower 102 is located at the lateral side of the evaporator 150, and does not occupy the space behind or in front of the evaporator 150, thereby reducing the space occupied by the cooling chamber 133 in the front-rear direction and securing the thickness of the foam between the rear of the cooling chamber 133 and the case of the cabinet.

In some embodiments, as shown in fig. 1, the cooling chamber 133 may be defined by the lowermost space in the freezing inner container, that is, the cooling chamber 133 is defined below the freezing inner container, and the freezing chamber 131 defined by the freezing inner container is located above the cooling chamber 133.

The blower 102 is disposed in the cooling compartment 133 on a first lateral side of the evaporator 150 and configured to cause at least a portion of the cooling air to flow through the freezer compartment air supply duct 160 into the freezer compartment 131.

In the conventional refrigerator 100, the cooling chamber 133 is generally disposed in the rear space of the cabinet, the freezing chamber 131 is generally disposed at the lowermost portion of the cabinet, and the compressor compartment is disposed at the rear lower portion of the freezing chamber 131, so that the freezing chamber 131 is inevitably formed as a special-shaped space giving way to the compressor compartment, thereby reducing the storage capacity of the freezing chamber 131 and causing the following problems. On one hand, the position of the freezing chamber 131 is low, so that a user can take and place articles in the freezing chamber 131 only by bending down or squatting down greatly, and the use of the user is inconvenient, especially for the old; on the other hand, since the depth of the freezing chamber 131 is reduced, in order to ensure the storage volume of the freezing chamber 131, the space in the height direction of the freezing chamber 131 needs to be increased, and when a user stores articles in the freezing chamber 131, the articles need to be stacked in the height direction, which is inconvenient for the user to find the articles, and the articles at the bottom of the freezing chamber 131 are easily shielded, so that the user is not easy to find the articles and forgets the articles, which causes deterioration and waste of the articles; furthermore, since the freezing chamber 131 is shaped and not a rectangular space, it is inconvenient to place some large and difficult-to-divide objects in the freezing chamber 131.

In this embodiment, the cooling chamber 133 is defined in the lower space in the freezing liner, so that the cooling chamber 133 occupies the lower space in the box body, that is, the bottom of the cooling chamber 133 is arranged, the freezing chamber 131 is located above the cooling chamber 133, the freezing chamber 131 is raised, the degree of bending of the user when the user takes and places articles in the freezing chamber 131 is reduced, and the use experience of the user is improved. Meanwhile, the cabinet body can define a press cabin at the rear lower part of the cooling chamber 133, that is, the press cabin is positioned at the rear lower part of the cooling chamber 133, the freezing chamber 131 does not need to give way for the press cabin any more, the storage volume of the freezing chamber 131 is ensured, and the freezing chamber 131 is a rectangular space, so that the goods can be stored in a flat-open manner instead of a stacked manner, a user can conveniently search the goods, and the time and the energy of the user are saved; meanwhile, the storage box is convenient for storing large and difficult-to-divide articles, and the problem that pain spots of large articles cannot be stored in the freezing chamber 131 is solved.

In the embodiment in which the cooling chamber 133 is located in the lower space inside the refrigerator body and the press cabin is located behind and below the cooling chamber 133, the thickness of the foaming material between the rear lower side of the cooling chamber 133 and the press cabin directly affects the refrigeration performance of the refrigerator, and in the patent of the applicant in the previous application, the blower 102 is disposed behind the evaporator 150, so that the size of the cooling chamber 133 in the front-back direction is increased, the space between the rear side of the cooling chamber 133 and the press cabin is small, the thickness of the foaming material between the cooling chamber 133 and the press cabin is reduced, and the refrigeration performance, the energy consumption and the like of the refrigerator 100 are affected to a certain extent.

The blower 102 is located at a first lateral side of the evaporator 150, and accordingly, the freezer compartment air supply duct 160 is located at an inner side of a first lateral wall of the freezer compartment, and at least one first air supply outlet communicating with the freezer compartment 131 is formed, and the blower 102 is configured to cause at least a part of the cooling air to flow toward the freezer compartment 131 through the freezer compartment air supply duct 160.

The evaporator 150 may be disposed in the cooling chamber in a flat cubic shape as a whole, that is, the long and wide faces of the evaporator 150 are parallel to the horizontal plane, the thickness face is disposed perpendicular to the horizontal plane, and the thickness dimension is significantly smaller than the length dimension of the evaporator 150. By placing the evaporator 150 horizontally in the cooling chamber 133, the evaporator 150 is prevented from occupying more space, and the storage capacity of the freezing chamber 131 in the upper portion of the cooling chamber 133 is secured.

A second lateral side wall of the cooling compartment 133, i.e., the second lateral side wall 1341 of the casing 134, is formed with a freezer return air inlet 134a for allowing a flow of return air from the freezer compartment 131 through the freezer return air path 170 into the cooling compartment 133 through the freezer return air inlet 134a for cooling by the evaporator 150 under the drive of the blower 102. The freezing compartment return air path 170 is defined by a gap between the lateral second sidewall of the freezing inner container 130 and the storage container 1311.

In the present embodiment, by arranging the blower 102 at a lateral side (e.g., a lateral first side) of the evaporator 150 and forming the freezing compartment return air inlet 134a communicating with the freezing compartment 131 at a lateral second side wall of the cooling compartment 133, the above-mentioned problem can be effectively solved, and the appearance of the front side of the cooling compartment 133 is more concise, and the user can have a better visual sense when opening the freezing compartment door 132.

Obviously, the second lateral side wall of the cooling compartment 133 (i.e., the second lateral side wall 1341 of the shroud 134) is laterally on the same side as the second lateral side wall 1301 of the freezing bladder 130, and accordingly, the variable temperature compartment return air inlet 130c is laterally on the same side as the freezing compartment return air inlet 134a, and the return air flow entering through the variable temperature compartment return air inlet 130c passes through the freezing compartment return air inlet 134a into the cooling compartment 133 to be cooled by the evaporator 150. Specifically, the return air flow of the variable temperature compartment 121 flows through the variable temperature compartment return air duct to the variable temperature compartment return air inlet 130c, and enters the cooling compartment 133 through the variable temperature compartment return air inlet 130c and the freezing compartment return air inlet 134a to be cooled by the evaporator 150, under the drive of the blower 102.

The freezing chamber 131 and the variable temperature chamber 121 are both air-cooled, the refrigerating chamber 11 can be directly cooled, and a refrigerating evaporator (not shown) is disposed in the refrigerating inner container and directly cools the refrigerating chamber 11.

Fig. 5 is a partially exploded view of the refrigerator 100 according to an embodiment of the present invention, fig. 6 is a schematic view of a housing of the refrigerator 100 according to an embodiment of the present invention, and fig. 7 is an enlarged view of a region a in fig. 6.

Generally, as shown in fig. 5, a compressor 104, a condenser 105 and a radiator fan 106 are disposed in a cabin defined in a cabinet, and the radiator fan 106 is configured to cause an air flow entering the cabin to sequentially pass through the condenser 105, the compressor 104, and then to flow out of the cabin. The heat dissipation fan 106 may be an axial flow fan. In this embodiment, the compressor 104, the heat dissipation fan 106, and the condenser 105 are sequentially disposed in the press cabin at intervals in the transverse direction.

In some embodiments, a section 1162 of the rear wall of the press compartment corresponding to the compressor 104 is formed with at least one rear air outlet hole 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 compressor compartment, and to complete the circulation of the heat dissipation airflow at the rear part of the compressor compartment; or the front wall and the rear wall of the press cabin are respectively provided with a vent hole to form a heat dissipation circulation air path in the front-back direction. In the face of the problem of increasing the heat dissipation effect of the compressor compartment, it is common for those skilled in the art to increase the number of the rear air inlet hole and the rear air outlet hole 1162a on the rear wall of the compressor compartment 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 utility model discloses the applicant jumps out conventional design thinking, creatively proposes a new scheme that is different from conventional design, the end air intake 110a that closes on condenser 105 that transversely arranges and the end air outlet 110b that closes on compressor 104 are injectd to the diapire at the box, accomplish the circulation of heat dissipation air current in the bottom of refrigerator 100, this space between refrigerator 100 and the holding surface has fully been utilized, need not to increase the distance of the back wall and the cupboard of refrigerator 100, when having reduced the shared space of refrigerator 100, guarantee the good heat dissipation in press cabin, fundamentally has solved the heat dissipation in press cabin of embedded refrigerator 100 and the pain point that can't obtain the balance between the space occupies, have especially important meaning.

The heat dissipation fan 106 is configured to force ambient air around the bottom intake vent 110a to enter the compressor compartment from the bottom intake vent 110a, and to sequentially pass through the condenser 105, the compressor 104, and then to flow from the bottom intake vent 110b to the external environment to dissipate heat from the compressor 104 and the condenser 105.

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, 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, the vent flap 108 is formed with a grill-like 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 particularly, the housing of the box also comprises a bottom plate, a support plate 112, two side plates 119 and a vertically extending back plate 116. The support plate 112 forms the bottom wall of the press cabin for carrying the compressor 104, the radiator fan 106 and the condenser 105, the two side plates 119 respectively form the two lateral side walls of the press cabin, and the vertically extending back plate 116 forms the rear wall of the press cabin.

More particularly, 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 located in the space defined by the supporting plate 112, the two side plates 119, the back plate and the bent section.
