Fig. 1 is a schematic configuration view of one direction of a refrigerator 100 according to one embodiment of the present invention, and fig. 2 is a schematic configuration view of another direction of the refrigerator 100 according to one embodiment of the present invention.

As shown in fig. 1, the refrigerator 100 may generally include a cabinet including a housing and a storage liner disposed inside the housing, a space between the housing and the storage liner is filled with a thermal insulation material (forming a foaming layer), the storage liner defines at least one storage compartment therein, the storage liner may generally include a freezing liner 130, a refrigerating liner, a temperature-changing liner, and the like, and the storage compartment may include a refrigerating chamber 11 defined by the refrigerating liner, a temperature-changing chamber 121 defined by the temperature-changing liner, and a freezing chamber 131 defined by the freezing liner 130. The front side of the storage liner is also provided with a door body to open or close the storage compartment, for example, the front side of the refrigeration liner is provided with a refrigerating chamber door body 12, the front side of the temperature-changing liner is provided with a temperature-changing chamber door body 122, and the front side of the freezing liner 130 is provided with a freezing chamber door body 132.

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 located laterally to the evaporator 150 and upstream of the evaporator 150 in the airflow path, and is configured to cause the return airflow in the at least one storage compartment to flow into the cooling compartment 133 to be cooled by the evaporator 150 and to cause a portion of the cooling airflow to flow into 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 130, that is, the cooling chamber 133 is defined below the freezing inner container 130, and the freezing chamber 131 defined by the freezing inner container 130 is located above the cooling chamber 133.

The blower 102 is disposed in the cooling compartment 133 on a second lateral side of the evaporator 150 and configured to cause at least a portion of the cooling air to flow through the freezer compartment blower 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 of the freezing chamber 131, and the freezing chamber 131 is inevitably formed as a special-shaped space to give 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 by the lower space in the freezing inner container 130, 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 foam 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 lower side of the cooling chamber 133 and the press cabin is small, the thickness of the foam 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.

In the embodiment, the applicant adjusts the position of the blower 102, and arranges the blower 102 at the lateral side of the evaporator 150, so as to avoid the blower 102 occupying the rear or front space of the evaporator 150, reduce the space occupied by the cooling chamber 133 in the front-rear direction, increase the space between the rear lower part of the cooling chamber 133 and the press cabin, and increase the thickness of the foaming material between the rear part of the cooling chamber 133 and the press cabin, thereby ensuring the refrigeration performance of the refrigerator 100 and reducing the energy consumption.

Since the blower 102 is located at the lateral second side of the evaporator 150, and accordingly, the freezing compartment blowing air duct 160 may be located inside the lateral first sidewall of the freezing compartment bladder 130, at least one first blowing outlet 160a communicating with the freezing compartment 131 is formed, the blower 102 is configured to cause at least part of the cooling air to flow toward the freezing compartment 131 through the freezing compartment blowing air duct 160.

Fig. 3 is a partial schematic view of the refrigerator 100 according to one embodiment of the present invention.

The refrigerator 100 further includes a cover (not shown) disposed in the freezing chamber 130 to cover the evaporator 150, and the cover and the bottom wall of the freezing chamber 130 define a cooling chamber 133. The lateral first side wall of the housing is formed with a side outlet 134b communicating with the inlet of the freezing chamber supply air 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.

As shown in fig. 1, a second lateral side wall of the cooling compartment 133 (i.e., a second lateral side wall of the casing) is formed with a freezing compartment return air inlet 134a so that a flow of return air of the freezing compartment 131 is introduced into the cooling compartment 133 through the freezing compartment return air inlet 134a via the freezing compartment return air path 170 by the blower 102 to be cooled by the evaporator 150. 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.

As shown in fig. 1, a freezing compartment return air inlet 134a formed in the second lateral side wall of the cooling compartment 133 (i.e., the second lateral side wall of the housing) is offset from a side air outlet 134b formed in the first lateral side wall of the housing, so that a return air flow entering the cooling compartment 133 through the freezing compartment return air inlet 134a passes through the evaporator 150, is cooled by the evaporator 150, and then flows into the freezing compartment supply air duct 160 through the side air outlet 134 b. With respect to the freezer supply air duct 160, the blower 102 is adjacent to the freezer return air inlet 134a, that is, the blower 102 is located upstream of the evaporator 150 in the air flow path, that is, on the second lateral side of the evaporator 150, specifically, between the second lateral side end face of the evaporator 150 and the freezer return air inlet 134 a.

In the prior art, the front side of the cooling chamber 133 (i.e., the front wall of the housing) is formed with a front return air inlet communicating with the freezing chamber 131, through which external impurities are easily introduced into the cooling chamber 133, and during defrosting of the evaporator 150, defrosting water may flow out from the front return air inlet, and when the freezing chamber door 132 is opened, a large amount of warm moisture may enter the cooling chamber 133 from the front return air inlet, thereby increasing the amount of frosting. In the present embodiment, by arranging the blower 102 at a lateral side (e.g., a lateral second side) of the evaporator 150 and forming the freezing compartment return air inlet 134a communicating with the freezing compartment 131 at the 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.

The temperature-variable liner of the refrigerator 100 is located above the freezing liner 130, and the temperature-variable chamber air supply duct (not shown) is disposed outside the first lateral wall of the temperature-variable liner, located in the foaming layer, and has at least one second air supply outlet (not shown) communicated with the temperature-variable chamber 121. The top end of the freezing chamber air supply duct 160 is provided with a variable temperature air door 103, and the variable temperature air door 103 can be controlled to be opened or closed so as to communicate the variable temperature chamber air supply duct with the freezing chamber air supply duct 160.

As shown in fig. 3, a variable temperature chamber return air inlet 130c is formed in a region of the transverse second side wall 1301 of the freezing inner container 130 corresponding to the evaporator 150, and a variable temperature chamber return air duct (not shown) is disposed outside the transverse second side wall of the variable temperature inner container and extends downward to communicate with the variable temperature chamber return air inlet 130 c.

Obviously, the second lateral side wall of the cooling compartment 133 (i.e., the second lateral side wall of the housing) is located on the same lateral side as the second lateral side wall of the freezing compartment 130, and accordingly, the variable temperature compartment return air inlet 130c is located on the same lateral 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.

A section of the bottom wall of the freezing inner container 130 directly below the evaporator 150 is referred to as a water receiving section, the water receiving section is substantially funnel-shaped and is used for receiving the defrosting water of the evaporator 150, the lowest point of the water receiving section is provided with the aforementioned water outlet 130b, the water outlet 130b is connected with a water outlet pipe 140, the defrosting water is conveyed to an evaporation pan (not numbered) located in the press cabin through the water outlet pipe 140, generally, the evaporation pan is located below the condenser 105, and the defrosting water in the evaporation pan absorbs the heat of the condenser 105 for evaporation.

Fig. 4 is a partially exploded view of the refrigerator 100 according to one embodiment of the present invention, fig. 5 is a schematic view of an outer case of the refrigerator 100 according to one embodiment of the present invention, and fig. 6 is an enlarged view of an area a of fig. 5.

As shown in fig. 4, a compressor 104, a condenser 105, and a radiator fan 106 are disposed in the cabin defined in the 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 idea of the design of the skilled person is to provide the rear wall of the compressor compartment with a rear air inlet hole facing the condenser 105 and with a rear air outlet hole 1162a facing the compressor 104, and to complete the circulation of the heat dissipating air flow at the rear 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.

While the applicant of the present invention has innovatively recognized that the heat exchange area of the condenser 105 and the vent area of the compressor compartment are not as large as possible, in conventional designs that increase the heat exchange area of the condenser 105 and the vent area of the compressor compartment, the problem of uneven heat dissipation of the condenser 105 can occur, 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, wherein the bottom wall of the box body is defined with the bottom air inlet 110a adjacent to the condenser 105 and the bottom air outlet 110b adjacent to the compressor 104 which are transversely arranged, the circulation of the heat dissipation air flow is completed at the bottom of the refrigerator 100, 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 is not required to be increased, the space occupied by the refrigerator 100 is reduced, and meanwhile, the good heat dissipation of the compressor compartment is ensured, the pain point that the balance cannot be obtained between the heat dissipation of the compressor compartment and the space occupation of the embedded refrigerator 100 is fundamentally solved, and the present invention has a particularly important significance.

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 the 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 if the heat exchange area of the condenser 105 is not increased, the ventilation area of the compressor compartment is reduced in an abnormal state, a better heat dissipation airflow path can be formed, and a better heat dissipation effect can still be achieved.

In the preferred scheme of the invention, the applicant breaks through the conventional design idea, the rear wall (back plate 116) of the press cabin and the plate section 1161 corresponding to the condenser 105 are designed into continuous plate surfaces, and the heat dissipation airflow entering the press cabin is sealed at the condenser 105, so that the ambient air entering from the bottom air inlet 110a is more concentrated at the condenser 105, the heat exchange uniformity of each condensation section of the condenser 105 is ensured, a better heat dissipation airflow path is formed, and a better heat dissipation effect can be achieved.

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.

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 cabinet generally has a plate-shaped bearing plate, the compressor 104 is disposed inside the bearing plate, and vibration generated during operation of the compressor 104 has a large influence on the bottom of the cabinet. In the embodiment, as mentioned above, the bottom of the box body 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 bearing the compressor 104, so as to reduce the influence of the vibration of the compressor 104 on other parts of the bottom of the box body. In addition, the box body is designed into the ingenious special structure, so that the structure of the bottom of the refrigerator 100 is compact, the layout is reasonable, the whole volume of the refrigerator 100 is reduced, meanwhile, 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.

Further specifically, the refrigerator 100 further includes a wind shielding strip 107 extending forward and backward, the wind shielding strip 107 being located between the bottom wind inlet 110a and the bottom wind outlet 110b, extending from the lower surface of the bottom horizontal section 113 to the lower surface of the supporting plate 112, and being 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 cabinet and the supporting surface is laterally partitioned, 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 under the action of the heat dissipation fan and to flow through the condenser 105, the compressor 104, and finally to 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 to ensure, further ensuring the heat dissipation efficiency.
