The evaporator is connected to the compressor 104, the condenser 105, the dry filter, and the capillary tube via a refrigerant line, and constitutes a refrigeration cycle circuit, and is cooled when the compressor 104 is started to cool air flowing therethrough.

In particular, in some embodiments, as shown in fig. 2, the freezing bladder 130 is located in a lower portion of the cabinet 100, defining therein a cooling chamber and a freezing chamber 132 located directly above the cooling chamber, and an evaporator (not shown) is disposed in the cooling chamber configured to cool the airflow entering the cooling chamber.

In the conventional refrigerator, the freezing chamber 132 is generally located at the lowest part of the refrigerator 10, so that the position of the freezing chamber 132 is low, and a user needs to bend down or squat down greatly to perform the operation of taking and placing articles in the freezing chamber 132, which is inconvenient for the user to use, especially for the elderly. And this embodiment is through setting up the cooling chamber in freezing inner bag 130 inside lower part space for the cooling chamber occupies the lower part space in freezing inner bag 130, has raised the height of freezer 132, reduces the degree of bowing that the user got when putting article operation to freezer 132, promotes user's use and experiences.

As shown in fig. 1 and fig. 2, two freezing chambers 132 are defined in the freezing inner container 130, a freezing drawer 137 is disposed in each of the two freezing chambers 132, and the freezing drawer 137 is disposed in the corresponding freezing chamber 132 in a front-back drawing manner. The refrigerating inner container 120 may further define therein a separate variable temperature chamber, for example, the refrigerating inner container 120 may define therein a variable temperature chamber (not numbered) located below the refrigerating chamber 121, the variable temperature chamber being separated from the refrigerating chamber above the variable temperature chamber by a partition. A refrigerating chamber door 136 is provided at a front side of the refrigerating inner container 120 to open or close the refrigerating chamber 121 and the temperature changing chamber.

In some embodiments, a blowing fan is disposed in the cooling chamber and configured to induce a flow of air cooled by the evaporator toward the freezing chamber 132, and an air inlet end of the freezing chamber blowing duct is connected and communicated with an air outlet end of the blowing fan and has a freezing chamber blowing port 141a communicated with the freezing chamber 132 to deliver a flow of cold air to the freezing chamber 132.

The front side of the hood panel 102 is formed with a front return air inlet 102a so that the return air flow of the freezing compartment 132 flows into the cooling compartment through the front return air inlet 102a to be cooled by the evaporator.

As is well known to those skilled in the art, the temperature within the refrigerated compartment 121 is generally between 2 ℃ and 10 ℃, preferably between 4 ℃ and 7 ℃. The temperature in the freezer compartment 132 is typically in the range of-22 c to-14 c. The temperature-changing chamber can be adjusted to-18 ℃ to 8 ℃ at will. The optimum storage temperatures for different kinds of articles are different and the suitable storage locations are different, for example, fruit and vegetable foods are suitable for storage in the refrigerating compartment 121 and meat foods are suitable for storage in the freezing compartment 132.

Fig. 3 is an exploded schematic view of a refrigerator 10 according to one embodiment of the present invention, fig. 4 is a schematic view of a cabinet 100 of the refrigerator 10 according to one embodiment of the present invention, and fig. 5 is an enlarged view of a region a of fig. 4.

Generally, the bottom of the cabinet 100 of the refrigerator 10 defines a compressor compartment, and the compressor 104, the condenser 105, and the heat dissipation fan 106 are disposed in the compressor compartment.

In particular, the bottom wall of the box 100 defines a bottom air inlet 110a and a bottom air outlet 110b which are laterally distributed side by side and communicate the compressor compartment with the surrounding environment, so as to form a heat dissipation circulation air path between the refrigerator 10 and the supporting surface, fully utilize the space between the refrigerator 10 and the supporting surface, avoid increasing the distance between the rear wall of the refrigerator 10 and the wall or the cabinet, reduce the space occupied by the refrigerator 10, and ensure good heat dissipation of the compressor compartment.

Further particularly, in this embodiment, the condenser 105 includes a first straight section 1051 extending laterally, a second straight section 1052 extending fore and aft, and a transition curve section 1053 connecting the first straight section 1051 and the second straight section 1052, thereby forming the L-shaped condenser 105. And the first straight section 1051 is adjacent to the bottom air inlet 110a, so that the air entering the press cabin from the bottom air inlet 110a first passes through the first straight section 1051, and takes away the heat of the first straight section 1051, thereby improving the overall heat dissipation effect of the condenser 105.

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 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, there is a problem of uneven heat dissipation from the condenser 105, which adversely affects the refrigeration system of the refrigerator 10. Therefore, the applicant of the present invention departs from the conventional design idea and creatively proposes a new scheme different from the conventional design, that is, the aforementioned L-shaped condenser 105 with a proper heat exchange area is adopted, and the specially designed bottom air inlet 110a and bottom air outlet 110b are defined at the bottom wall of the box body 100, so that the circulation of the heat dissipation air flow is completed at the bottom of the refrigerator 10, the space between the refrigerator 10 and the supporting surface is fully utilized, the distance between the rear wall of the refrigerator 10 and the cabinet does not need to be increased, the space occupied by the refrigerator 10 is reduced, and the good heat dissipation of the compressor chamber is ensured, thereby fundamentally solving the pain point that the balance cannot be obtained between the heat dissipation of the compressor chamber and the space occupation of the embedded refrigerator 10, and having a particularly important significance.

As shown in fig. 4, the refrigerator 10 further includes a heat dissipation fan 106, and the compressor 104, the heat dissipation fan 106 and the condenser 105 are arranged in the press cabin at intervals in the transverse direction, wherein a side wall adjacent to the condenser 105 in two transverse side walls of the press cabin is referred to as a first side wall 1191, and a side wall adjacent to the compressor 104 is referred to as a second side wall 1192. Relative to the second side wall 1192, the second straight section 1052 is closer to the first side wall 1191, i.e. the second straight section 1052 should be close to the first side wall 1191, inside the first side wall 1191. The heat rejection blower 106 is configured to draw ambient air from the bottom inlet 110a and force the air to flow through the first straight section 1051, then through the compressor 104, and then from the bottom outlet 110b to the ambient environment, thereby cooling the condenser 105 and 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.

The lateral distance between the end of the first straight section 1051 adjacent to the heat dissipation fan 106 and the heat dissipation fan 106 may be 50mm to 180mm, so as to ensure a proper spacing space between the first straight section 1051 and the heat dissipation fan 106, thereby facilitating the sufficient contact between the condenser 105 and the air flow.

More particularly, the first side wall 1191 may be formed with a first side vent 1191a, so that the ambient air around the first side vent 1191a enters the press cabin through the first side vent 1191a under the driving of the cooling fan 106, and cools the second straight section 1052, thereby adding an air path for air intake from the side of the press cabin to the air intake from the bottom of the box 100.

Further in particular, in a preferred embodiment of the invention, the plate segment 1161 of the back plate 116 (of the rear wall of the nacelle) facing the first straight segment 1051 is a continuous plate surface, that is to say the plate segment 1161 of the back plate 116 facing the first straight segment 1051 is free of heat dissipation portholes.

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.

Accordingly, in the preferred embodiment of the present invention, the applicant breaks through the conventional design concept, and designs the plate section 1161 of the rear wall (back plate 116) of the press cabin and the condenser 105 as a continuous plate surface, and seals the heat dissipation airflow entering the press cabin at the condenser 105, so that the ambient air entering the first side vent 1191a and the ambient air entering from the bottom air inlet 110a are more concentrated at the condenser 105, thereby ensuring the heat exchange uniformity of each condensation section of the condenser 105, facilitating the formation of a better heat dissipation airflow path, and also achieving a better heat dissipation effect.

In addition, the ambient air entering from the first side vents 1191a 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 compressor is further concentrated at the condenser 105, and the uniformity of the overall heat dissipation of the condenser 105 is ensured.

As shown in fig. 3, the second side wall 1192 is formed with a second side vent 1192a, so that under the action of the heat dissipation fan 106, a part of the airflow after passing through the compressor 104 flows from the second side vent 1192a to the ambient environment, thereby increasing an air path for discharging air from the side of the box 100 on the basis of discharging air from the bottom of the box 100, and ensuring the heat dissipation effect of the compressor compartment.

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. Under the driving of the heat dissipation fan 106, after the air entering the cabin sequentially passes through the condenser 105 and the compressor 104, part of the air flow is blown out from the bottom air outlet 110b, part of the air flow is blown out from the second side vent 1192a, and part of the air flow is blown out from the rear air outlet 1162a, so that the heat dissipation air flow can be blown out from the bottom, the side and the rear of the cabin, the smooth circulation of the heat dissipation air flow is further ensured, and the heat dissipation effect of the cabin is improved.

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.

As shown in fig. 1 and 4, the outer shell of the refrigerator 10 includes two box side plates 111 in the transverse direction, the two box side plates 111 extend vertically to form two side walls of the refrigerator 10, a first side opening (not shown) communicated with the first side vent 1191a is formed on the box side plate 111 adjacent to the first side vent 1191a, and a second side opening 111a communicated with the second side vent 1192a is formed on the box side plate 111 adjacent to the second side vent 1192a, so that the ambient air outside the refrigerator 10 sequentially passes through the first side opening, the first side vent 1191a enters the interior of the compressor compartment, and partial air flow after heat exchange with the compressor 104 sequentially passes through the second side vent 1192a and the second side opening 111a to flow out of the refrigerator 10, thereby ensuring the heat dissipation effect of the compressor compartment.

As shown in fig. 3, a first vent cover plate 1081 is disposed on the first side vent holes 1191a, a second vent cover plate 1082 is disposed on the second side vent holes 1192a, the first vent cover plate 1081 covers the first side vent holes 1191a, the second vent cover plate 1082 covers the second side vent holes 1192a, and grille-type vent holes are formed in both the first vent cover plate 1081 and the second vent cover plate 1082.

The first and

second side vents

1191a and 1192a may be circular, and accordingly, the first and second side openings 111a may also be circular, so as to maintain the aesthetic appearance of the refrigerator.

Fig. 6 is a schematic diagram of a condenser assembly of the refrigerator 10 according to one embodiment of the present invention.

In the case of the refrigerator 10 having the lowest refrigeration chamber in the prior art or the refrigerator 10 having the lowest cooling chamber in one embodiment of the present invention, in order to increase the space of the storage chamber under the condition that the overall height of the refrigerator 10 is the same, a technician needs to reduce the height of the compressor compartment as much as possible during design, which makes the space of the compressor compartment itself limited, and how to improve the heat dissipation effect of the compressor compartment in such a limited space, the applicant further uniquely designs the structure of the condenser 105, and matches the special structure of the condenser 105 with the heat dissipation circulation air passage of the compressor compartment, so as to achieve more efficient heat dissipation.

The transverse dimension of the compressor compartment is generally larger than the front and rear dimensions, in this embodiment, the dimension of the transverse extending direction of the first straight section 1051 may be larger than the dimension of the front and rear extending direction of the second straight section 1052, that is, the first straight section 1051 is the long side of the L-shaped condenser, and the second straight section 1052 is the short side of the L-shaped condenser, so that the air flow entering the compressor compartment from the bottom air inlet 110a can exchange heat with the second straight section 1052 with a larger dimension, thereby further improving the overall heat dissipation effect of the condenser 105.

In some embodiments, as shown in fig. 6, condenser 105 may be a parallel flow condenser. The first straight section 1051 of the condenser 105 includes a plurality of first flat straight pipes which are distributed in parallel in the height direction and extend laterally; the second straight section 1052 includes a plurality of second flat straight tubes, which are distributed in parallel in the height direction and extend forward and backward; the transition curved section 1053 includes a plurality of curved tubes connecting and communicating a plurality of first flat straight tubes and a plurality of second flat straight tubes, and the first flat straight tubes, the second flat straight tubes and the curved tubes are in the same number and are in one-to-one correspondence.

The inlet connection pipe 1058 is provided with a damper 1054 to reduce noise transmitted from the compressor 104 to the inlet connection pipe 1058.

During operation, high temperature refrigerant gas discharged from the compressor 104 enters the collecting pipe 1057 connected with the inlet connecting pipe 1058 through the inlet connecting pipe 1058, and enters the second flat straight pipe, the curved pipe and the first flat straight pipe from the collecting pipe 1057, and heat transfer is performed to air flowing through the condenser through the second flat straight pipe, the curved pipe, the first flat straight pipe and the radiating fin, so that the refrigerant gradually changes from a gas state to a liquid state, then flows to the drying filter from the outlet connecting pipe 1059 connected with the other collecting pipe 1057, and then changes into a gas-liquid mixture with a certain gas proportion at a low pressure and a low temperature through the capillary tube, and enters the evaporator to cool the air around the evaporator.

In some embodiments, as shown in fig. 3-5, the housing of the case 100 further includes a bottom panel, a support panel 112, two side panels 119, and a vertically extending back panel 116.
