In the conventional refrigerator 100, the lowermost space of the refrigerator 100 is generally a storage space, the storage space is located at a lower position, and a user needs to bend down or squat down greatly to perform an operation of taking and placing objects in the lowermost storage space, which is inconvenient for the user to use, especially for the old; and, because the evaporimeter has taken up the rear region of below storing space for the depth of below storing space reduces, moreover, because the press cabin is located the rear portion of below storing space generally, below storing space inevitably will give way for the press cabin, leads to below storing space dysmorphism, is not convenient for the deposit of the great and difficult segmentation article of volume.

In the refrigerator 100 of the embodiment, the space at the lowest part of the refrigerator 100 is the cooling chamber, the height of the first chamber 131 above the cooling chamber is raised, the stooping degree of the user when the user takes and places articles in the first chamber 131 is reduced, and the use experience of the user is improved.

As shown in fig. 4, the dashed arrow in fig. 4 shows the return air flow direction of the second compartment 132, and the refrigerator 100 of the embodiment delivers the return air of the second compartment 132 into the cooling compartment through the first return air duct 103 located in the foamed layer and the second return air duct 109 located in the first door panel 133, so that the return air of the second compartment 132 flows back into the cooling compartment and is cooled by the evaporator 101.

In the existing refrigerator 100, the return air pipe is generally located in the foaming layer on the transverse side of the storage liner, and occupies the transverse space of the refrigerator 100, and in this embodiment, a part of the return air pipe (the second return air pipe 109) is arranged in the first door plate 133, so that the space in the first door plate 133 which is originally empty is utilized, and the transverse space of the refrigerator 100 is saved, so that the transverse size of the refrigerator 100 can be reduced on the premise of ensuring the storage volume, or the thickness of the foaming material between the storage liner and the shell is increased under the condition of keeping the transverse size of the refrigerator 100 unchanged.

The first air return duct 103 and the second air return duct 109 can both be flat, so as to reduce the occupied space of the air return ducts.

Since the first compartment 131 is located right above the cooling compartment and the front side of the casing 102 that separates the cooling compartment from the first compartment 131 has the front return air inlet 102a, the space of the first compartment 131 and the cooling compartment can be communicated through the front return air inlet 102a, and therefore, the return air in the first compartment 131 directly flows back into the cooling compartment through the front return air inlet 102 a.

In the first embodiment, as shown in fig. 2 to 4, the second compartment 132 is defined by the first inner container 130, that is, the first inner container 130 defines the second compartment 132, the first compartment 131 and the cooling chamber which are sequentially distributed from top to bottom. Specifically, a transverse partition plate 160 is disposed in the first inner container 130, and the transverse partition plate 160 divides a space of the first inner container 130 above the cooling chamber into the second compartment 132 located above and the first compartment 131 located below.

In the first embodiment, as shown in fig. 1, the refrigerator 100 further includes a third inner container (not shown because it is shielded by the outer case 110) located above the first inner container 130, the third inner container defines a third compartment, which may be a refrigerating compartment, and the front side of the third inner container is provided with two split door bodies 122. In this embodiment, the second compartment may be a variable temperature compartment.

In the first embodiment, the refrigerator 100 further includes a blower (not shown) configured to cause the air flow cooled by the evaporator 101 to flow into the first compartment 131 through the first blowing duct 140 and further into the second compartment 132 through the second blowing duct 150, and a first blowing duct 140 and a second blowing duct 150.

The blower may be disposed at the rear of the evaporator 101, the first blowing duct 140 may be located at a position corresponding to the first compartment 131 inside the rear wall of the first inner container 130, communicate with the cooling chamber, and have a first blowing port 140a communicating with the first compartment 131, and the second blowing duct 150 may be located at a position corresponding to the second compartment 132 inside the rear wall of the first inner container 130, and controllably communicate with the upper end of the first blowing duct 140 through a damper (not shown).

As is well known to those skilled in the art, the temperature in the refrigerated compartment is generally between 2 ℃ and 10 ℃, preferably between 4 ℃ and 7 ℃. The temperature in the freezer compartment is typically in the range of-22 deg.C to-14 deg.C. The temperature-changing chamber can be adjusted to-18 ℃ to 8 ℃ at will. The optimum storage temperatures for different types of articles are different and the locations suitable for storage are different, for example, fruit and vegetable foods are suitable for storage in the cold room and meat foods are suitable for storage in the freezer room.

As shown in fig. 5, the first door panel 133 includes a door case 1331 at a front side and a door liner 1332 disposed at a rear side of the door case 1331, and the second return air duct 109 is disposed between the door case 1331 and the door liner 1332. A connection end 133a protruding backward is formed at a position of the rear wall surface of the door liner 1332 corresponding to the upper end of the second return duct 109, and a third opening 133a1 matched with the first opening 131a is formed at the connection end 133 a; when the first door 133 is closed, the connection end 133a is inserted into the first compartment 131, and the third opening 133a1 communicates with the first opening 131a, thereby communicating the upper end of the second return duct 109 with the first opening 131 a. A fourth opening 133b is formed in the rear wall surface of the door liner 1332 at a position corresponding to the lower end of the second return duct 109, and when the first door panel 133 is closed, the fourth opening 133b communicates with the front return air inlet 102a, thereby communicating the lower end of the second return duct 109 with the cooling compartment. Therefore, when the first door panel 133 is closed, the upper end (namely, the air inlet end) of the second air return pipe 109 is communicated with the lower end (namely, the air outlet end) of the first air return pipe 103, and the lower end (namely, the air outlet end) of the second air return pipe 109 is communicated with the cooling chamber, so that the return air of the second compartment 132 flows back to the cooling chamber.

As shown in fig. 4 and 5, the first opening 131a is adjacent to the front upper end of the first compartment 131, and accordingly, the connection end is formed at the rear wall surface of the door liner adjacent to the lateral side upper end, and the second opening 132a is adjacent to the front lower end of the second compartment 132. Since the second blowing duct 150 blows air into the second compartment 132 from the rear side, and the return air in the second compartment 132 enters the first return duct 103 from the second opening 132a near the front lower end of the lateral side portion, the cold air flow entering the second compartment 132 flows through the entire second compartment 132 from the rear side to the front side, and then flows back into the first return duct 103 from the second opening 132a located in the front of the lateral side portion, thereby ensuring the uniformity of the temperature in the second compartment 132.

In some embodiments, the number of the first openings 131a is two, two first openings 131a are respectively formed on two lateral sidewalls of the first compartment 131, two second openings 132a are respectively formed on two lateral sidewalls of the second compartment 132, and accordingly, the number of the first air return duct 103, the number of the second air return duct 109, the number of the connecting ends 133a, and the number of the fourth openings 133b are two. The two second return ducts 109 are laterally spaced apart, and two connection ends 133a are formed at positions adjacent to the two lateral sides of the rear wall surface of the door liner 1332, respectively. Of these, only one second return air duct 109 is shown in fig. 5.

In some embodiments, the press cabin may be located below and behind the first inner container 130, and as described above, the first compartment 131 does not need to give way to the press cabin any more, so that the depth of the first compartment 131 is ensured, and it is convenient to place a large-sized object which is not easy to be divided.

As shown in fig. 6, the refrigerator 100 further includes a heat dissipation fan 106, the heat dissipation fan 106 may be an axial flow fan, and the compressor 104, the heat dissipation fan 106, and the condenser 105 are sequentially arranged in the press compartment at intervals along 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 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, the bottom wall of the refrigerator 100 is limited to the bottom air inlet 110a located below the front of the condenser 105 and the bottom air outlet 110b located below the front of 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 the good heat dissipation of the compressor compartment is ensured, thereby fundamentally solving the pain point that the heat dissipation of the compressor compartment of the embedded refrigerator 100 and the space occupation cannot be balanced, and having 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 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 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 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 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 refrigerator body 100. In the embodiment, as mentioned above, the bottom of the box 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 100. In addition, by designing the box body 100 into the above-mentioned ingenious special structure, the structure of the bottom of the refrigerator 100 is compact and reasonable in layout, the whole 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.
