The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The refrigeration device of the present invention includes a refrigerator and an ice chest, and in order to make the technical solution of the present invention clearly understood by those skilled in the art, the refrigeration device of the present invention will be described in detail by taking the refrigerator as an example and combining with the attached drawings.

Fig. 1 is a schematic view showing the distribution of compartments of a refrigerator according to some embodiments of the present invention, and fig. 2 is a schematic view showing the connection of main components of a refrigeration system according to some embodiments of the present invention. It should be noted that fig. 2 shows only the main components of the refrigeration system, and actually, the refrigeration system of the refrigerator further includes other structures such as control valves, pipelines, and the like.

As shown in fig. 1 and 2, in some embodiments of the present invention, the refrigerator mainly includes a machine body 1, a compressor 2, a condensing assembly 3, a refrigerant depressurizing device 4 and an evaporator 5. The compressor 2, the condensing assembly 3 (specifically, the condenser 32 marked in fig. 8), the refrigerant pressure reducing member 4, and the evaporator 5 are fluidly connected together, so that the refrigerant can flow in sequence through the compressor 2, the condensing assembly 3 (specifically, the condenser 32), the refrigerant pressure reducing member 4, and the evaporator 5.

The pressure reducing member 4 may be a capillary tube, or may be a member having a throttling function and/or a pressure reducing function.

As shown in fig. 1, the machine body 1 is provided with a press cabin 11, a refrigeration chamber 12 and a storage chamber 13. Wherein, the press cabin 11 is located at the bottom of the machine body 1 and at least used for arranging the compressor 2 and the condensing assembly 3. The refrigeration compartment 12 is used at least for arranging the evaporator 5. The storage chamber 13 is used for storing food materials.

Fig. 3 to 7 show the structure of the press hopper section.

As shown in fig. 3 to 7, the bottom wall of the press cabin 11 is provided with an air inlet 111 and an air outlet 112. In a normal use state of the refrigerator, a gap (not labeled) is formed between the bottom wall of the press chamber 11 and the ground, so that outside air enters the press chamber 11 from the air inlet 111, cools the compressor 2 and the condensing assembly 3 (specifically, the condenser 32), and then flows out of the press chamber 11 from the air outlet 112.

As shown in fig. 5, the machine body 1 further includes a wind shielding member 14 disposed at a bottom side of the bottom wall of the press cabin 11, and the wind shielding member 14 divides a gap between the bottom wall of the press cabin 11 and the ground into a wind inlet channel (not marked in the figure) and a wind outlet channel (not marked in the figure); so that the outside air enters the press chamber 11 through the air inlet channel and the air inlet 111, and flows to the environment around the refrigerator through the air outlet 112 and the air outlet channel. The hot air flowing out of the air outlet 112 is prevented from entering the press cabin 11 from the air inlet 111 again, and the heat dissipation effect of the press cabin 11 is prevented from being influenced.

Preferably, the wind shielding member 14 is inclined from the rear to the front in a direction close to the wind outlet 112 to reduce the wind resistance of the wind inlet passage, so that the outside air can more easily enter the press cabin 11, and the air cooling performance of the press cabin 11 is optimized.

As shown in fig. 3 to 7, grills for preventing foreign substances (e.g., hamsters, cats, parrots, and other small animals) from entering the press cabin 11 are installed at the air inlet 111 and the air outlet 112.

As shown in fig. 8, the condensing assembly 3 includes an air duct 31, a condenser 32, and a condensing fan 33. Wherein, be formed with air cavity 311 in the dryer 31, the circumference wall of dryer 31 and the circumference wall butt of press storehouse 11 to make the whole wind cavities 311 that flow through of air in the press storehouse 11. It will be understood by those skilled in the art that, in consideration of the manufacturing cost and/or the assembly cost, the peripheral wall of the air duct 31 and the peripheral wall of the press cabin 11 may not be in complete sealing abutment, and a slight gap is left so that most of the air in the press cabin 11 flows through the air chamber 311.

As shown in fig. 7 and 8, the condenser 32 is disposed in the air cavity 311 and is fitted into the air duct 31, in other words, the outer circumferential wall of the condenser 32 abuts against the inner circumferential wall of the air duct 31, so that the air flowing through the air cavity 311 can pass through the air duct holes in the condenser 32, or the air passes through the air duct holes in the condenser 32 for most of the air to pass through the air duct holes in the condenser 32 for less of the air to be blown from the outside of the circumferential wall of the condenser 32. As will be understood by those skilled in the art, the condenser 32 and the wind barrel 31, which are fitted together, can improve the utilization rate of the air in the compressor compartment 11 to cool the condenser 32.

Further, the condensing fan 33 is also provided in the air chamber 311, and is fixed together with the air duct 31 and/or the condenser 32. Preferably, the condensing fan 33 is located at a side of the condenser 32 close to the compressor 2. When the condensing fan 33 rotates forward, the external air can be driven to enter the press cabin 11 from the air inlet 111, and after cooling the compressor 2 and the condenser 32, the air flows out of the press cabin 11 from the air outlet 112. Alternatively, the condensing fan 33 may be disposed on a side of the condenser 32 away from the compressor 2 as required by those skilled in the art.

It can be understood by those skilled in the art that the air duct 31, the condenser 32 and the condensing fan 33, which are fixed to each other, can facilitate the worker to install and remove the three into and from the press cabin 11.

In some such embodiments of the invention, condenser 32 is a microchannel condenser. Furthermore, the condenser 32 may be configured as any other feasible condenser, such as a tube condenser, as desired by one skilled in the art.

Further, on the premise that it can be ensured that all or most of the air in the press cabin 11 flows through/blows the condenser 32, in other embodiments of the present invention, a person skilled in the art may also omit the arrangement of the air duct 31 and match the circumference of the condenser 32 with the inner circumferential wall of the press cabin 11, so that the circumferential wall of the condenser 32 abuts against the inner circumferential wall of the press cabin 11.

As shown in fig. 6 and 7, the refrigerator further includes a liquid reservoir 6 and a condensation duct 7 disposed inside the press compartment 11. Wherein, the liquid storage device 6 is used for containing condensed water and/or defrosting water of the refrigerator. In particular, the refrigerator also comprises a drain (not marked in the figures), one end of which opens into the refrigeration compartment 12 and the other end of which extends to the reservoir 6, so as to allow the condensed and/or defrosted water inside the refrigeration compartment 12 to flow into the reservoir 6 through the drain. One end of the condensation pipe 7 is connected with the outlet of the compressor 2; the other end of the condenser tube 7 is connected to an inlet of the condenser 32 to fluidly connect the compressor 2 and the condenser 32 together.

With continued reference to fig. 6 and 7, the accumulator 6 is disposed on a side of the condenser 32 away from the compressor 2, such that the accumulator 6 and the compressor 2 are disposed on two sides of the condenser 32, and further, the accumulator 6 and the air inlet 111 are disposed on a same side of the condenser 32, and the compressor 2 and the air outlet 112 are disposed on a same side of the condenser 32.

As shown in fig. 7, the reservoir 6 is provided as a container having a large opening at the top, and specifically, the reservoir 6 includes a bottom wall and a peripheral wall that enclose the reservoir 6 into an open container without a top wall.

Alternatively, the condensing fan 33 is configured to be capable of reverse rotation. The contra-rotating condenser fan 33 causes air to enter the press compartment 11 from the air outlet 112 and to exit the press compartment 11 from the air inlet 111. In the process, the air flow blows against the condenser 32 in a reverse direction, blowing off dust on the surface of the condenser 32 in a direction away from the compressor 2. Some of the dust blown off from the condenser 32 falls into the reservoir 6 through the opening of the reservoir 6 and mixes with the condensed water, avoiding blowing out of the press compartment 11 and contaminating the environment around the refrigerator.

With continued reference to fig. 6 and 7, a portion of the condenser tube 7 is disposed in the reservoir 6 to serve as a heater 71 for heating the condensed water and/or defrosted water in the reservoir 6 to promote melting of the frost and evaporation of the condensed water. Further, the condensation duct 7 is fixed as the part of the heater 71 by a snap (not shown) fixed to the bottom wall and/or the side wall of the reservoir 6. When the high-temperature refrigerant flowing out of the compressor 2 flows through the portion of the condensation pipe 7, heat is transferred to the condensed water and/or the defrosted water in the accumulator 6 through the portion, thereby promoting melting of the frost and evaporation of the condensed water.

In addition, in other embodiments of the present invention, the heater 71 may be replaced by other structures or members with smaller height by those skilled in the art according to the requirement. The heater 71 is provided as a micro-channel radiator connected in series between the compressor 2 and the condenser 32 or between the condenser 32 and the refrigerant depressurizing means 4, for example.

Although not shown, in other embodiments of the present invention, one skilled in the art may omit the heater 71 (i.e., keep the condenser tube 7 from heating the condensed and/or defrosted water) and then periodically pour the reservoir 6 as desired.

Further, in other embodiments of the present invention, a person skilled in the art may also arrange the storage chamber drainage channel to extend into the storage chamber 13 and extend the other end of the storage chamber drainage channel to the right above the liquid reservoir 6, as required, so as to drain the liquid in the storage chamber 13 into the liquid reservoir 6.

As shown in fig. 4 and 7, the air intake opening 111 is provided at one side of the reservoir 6, preferably, directly in front of the reservoir 6.

As shown in fig. 4, the refrigerator further includes an air guide structure 8 disposed in the press compartment 11, and the air guide structure 8 is configured to guide the air entering the press compartment 11 from the air inlet 111 into the liquid reservoir 6. Specifically, the air guiding structure 8 includes a side wall of the liquid reservoir 6 near the air inlet 111 and a side wall of the press cabin 11 near the air inlet 111. The side wall of the press cabin 11 near the air inlet 111 is an inclined structure, and specifically, the side wall gradually inclines backwards from the bottom end to the top end.

In addition, in other embodiments of the present invention, the skilled person can also set the air guiding structure 8 to any other feasible structure, for example, an arc-shaped plate disposed in the pressing chamber 11, the bottom end of the arc-shaped plate is disposed at the front side of the air inlet 111, and the top end of the arc-shaped plate extends to the right above or inside the liquid reservoir 6.

Based on the foregoing description, it can be understood by those skilled in the art that, according to the present invention, the compressor 2 and the liquid accumulator 6 are respectively disposed at two sides of the condensing assembly 3, so that the three components are complementarily overlapped in the vertical direction, the height of the press cabin 11 is effectively reduced, and the volume of the storage chamber 13 is effectively increased under the condition that the overall height of the refrigerator is not changed.

Further, the air entering the press cabin 11 is fully utilized by making the air flow through the condenser 32 and blowing the condenser 32, so that the heat dissipation effect of the condenser 32 is improved.

So far, the technical solution of the present invention has been described in connection with the foregoing embodiments, but it is easily understood by those skilled in the art that the scope of the present invention is not limited to these specific embodiments. Without departing from the technical principle of the present invention, a person skilled in the art may split and combine the technical solutions in the above embodiments, and may make equivalent changes or substitutions for related technical features, and any changes, equivalents, improvements, etc. made within the technical concept and/or technical principle of the present invention will fall within the protection scope of the present invention.
