Fig. 3 is a schematic partial enlarged view of the refrigerator 100 shown in fig. 1. The refrigerator 100 according to an embodiment of the present invention may generally include a refrigerator body 110, the refrigerator body 110 includes a casing 111 and a storage liner disposed inside the casing 111, a space between the casing 111 and the storage liner is filled with a thermal insulation material (forming a foaming layer 112), the storage liner defines a storage compartment therein, and may generally include a freezing liner 114, a refrigerating liner 113, and the like, and the storage compartment includes a freezing compartment defined in the freezing liner 114 and a refrigerating compartment defined in the refrigerating liner 113.

As is well known to those skilled in the art, the temperature of 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 optimum storage temperatures for different types of items are different and the locations suitable for storage are different, for example, fruit and vegetable foods are suitable for storage in the cold storage compartment and meat foods are suitable for storage in the cold storage compartment.
The refrigerator 100 according to the embodiment of the present invention further includes an evaporator 500, an air supply fan, a compressor 801, a condenser 803, a heat radiation fan 802, a throttling element (not shown in the figure), and the like. The evaporator 500 is connected to the compressor 801, the condenser 803, and the throttle element via refrigerant lines to constitute a refrigeration cycle, and is cooled when the compressor 801 is started to cool air flowing therethrough. The compressor 801, the condenser 803, and the radiator fan 802 are provided in the compressor compartment 800.
The refrigerator 100 according to the embodiment of the present invention has a cooling chamber 150 defined in a lower portion thereof in the cabinet 110, an evaporator 500 disposed in the cooling chamber 150, and all storage compartments located above the cooling chamber 150. In some embodiments, the freezer inner container 114 is located in a lower portion of the cabinet 110 and defines therein the aforementioned cooling chamber 150 and a freezer compartment located directly above the cooling chamber 150. In the conventional refrigerator, the freezing compartment is generally located at the lowest part of the refrigerator 100, so that the freezing compartment is located at a lower position, a user needs to bend down or squat greatly to perform the operation of taking and placing objects in the freezing compartment, and the refrigerator is inconvenient for the user to use and especially inconvenient for the old to use. Moreover, the freezing chamber needs to give way for the press cabin 800, and the freezing chamber inevitably needs to be made into a special-shaped space for giving way for the press cabin 800, so that the storage volume of the freezing chamber is reduced. The cooling chamber 150 is limited below the storage chamber, so that the cooling chamber 150 occupies the lower space of the box body 110, the height of the freezing chamber is raised, the bending degree of a user when the user takes and places articles in the freezing chamber is reduced, and the use experience of the user is improved; moreover, the cooling chamber 150 can provide a yield for the press cabin 800, and the freezing chamber does not need to provide a yield for the press cabin 800 any more, so that the problem that the freezing chamber is irregular due to the fact that the freezing chamber needs to provide a yield for the press cabin 800 in the existing scheme is solved, and the depth and the storage volume of the freezing chamber can be guaranteed.
In some embodiments, the evaporator 500 of the refrigerator 100 of the embodiment of the present invention is disposed in the cooling compartment 150 in a left-right direction as a whole, and the evaporator 500 has at least three bent structures 550 in the left-right direction, configured to cool the airflow entering the cooling compartment 150 to form the cooling airflow. Through transversely arranging evaporator 500 in cooling chamber 150, avoid evaporator 500 to occupy more spaces, guarantee the storage volume of the freezing room of cooling chamber 150 top, evaporator 500 has at least three bending structure 550 in the left and right directions simultaneously, compares with the rectangle evaporator, and evaporator 500's pipeline length increases, has improved evaporator 500's heat transfer performance, has reduced the energy consumption of refrigerator 100.
The evaporator 500 of the refrigerator 100 according to the embodiment of the present invention may be a fin tube type evaporator, and includes a body part and a heating wire 503. The body portion is used for cooling the airflow entering the cooling chamber 150 and comprises a plurality of fins 501 arranged in parallel and a coil 502 penetrating through the fins 501. Heating wires 503 are embedded in the upper and lower ends of the plurality of parallel fins 501, respectively, for supplying heat required for defrosting.
The refrigerator 100 according to the embodiment of the present invention further includes a water pan 300, a water conduit 400, and an evaporating dish 804. A drain pan 300 is provided on the bottom wall of the cooling chamber 150 to receive condensed water generated by the evaporator 500 and defrosted water generated by defrosting. The front section bottom wall and the rear section bottom wall of the cooling chamber 150 are inclined surfaces inclined downward in the direction of each other, and the water pan 300 has a first inclined portion 301 attached to the front section bottom wall of the cooling chamber 150 and a second inclined portion 302 attached to the rear section bottom wall of the cooling chamber 150. A water outlet 303 is arranged at the intersection of the first inclined part 301 and the second inclined part 302, and the water outlet 303 is at the lowest point of the water pan 300. The drain 303 is connected via a water conduit 400 to an evaporation pan 804 located in the compressor compartment 800. Preferably, the included angles between the front-section bottom wall and the horizontal plane and between the rear-section bottom wall of the cooling chamber 150 and the horizontal plane are both greater than or equal to 5 ℃, so that condensed water generated by the evaporator 500 can smoothly enter the water pan 300, and can be completely discharged, thereby effectively ensuring the working reliability of the evaporator 500. A support member 304 also extends upward from the second inclined portion 302 of the drip tray 300.
In some embodiments, the evaporator 500 of the refrigerator 100 according to the embodiment of the present invention further has a support portion 504 extending downward from the bottom of the body portion, and the support portion 504 cooperates with the support member 304 to keep the body portion of the evaporator 500 and the heating wire 503 away from the water discharge opening 303. In the refrigerator 100 with the transverse evaporator 500, during the cooling process, the hot and humid air in the compressor compartment 800 reaches the evaporator 500 through the water conduit 400 and the water outlet 303. For example, hot and humid air having an ambient temperature of 32 ℃ and a relative humidity of 85% flows from the compressor compartment 800 through the water conduit 400 and the water discharge port 303 to the evaporator 500, and the temperature around the water discharge port 303 is about 20 ℃. Since the temperature of the freezing evaporator is-25 ℃, and the distance between the evaporator and the water outlet 303 of the conventional refrigerator is relatively short, when the frost on the evaporator is melted by the air at about 20 ℃, the evaporator cools, the frost on the bottom surface of the evaporator melts, and solid ice blocks are formed at the bottom of the evaporator. Due to the power limitation of the heating wire 503, the ice cubes may not be completely melted into water and may fall into the water outlet 303 as a whole, thereby blocking the water outlet 303. The end result is that later defrosted water cannot be discharged from the drain 303, resulting in freezing of the entire evaporator, reduced heat exchange performance, or no cooling. In the invention, the supporting part 504 is arranged at the bottom of the evaporator 500 to raise the height from the body of the evaporator 500 to the water outlet 303, for example, the distance between the body of the evaporator 500 and the water outlet 303 is increased by 1.2-2 times compared with the existing evaporator, so that the temperature of the air reaching the bottom of the evaporator 500 is about 0 ℃, ice blocks are not generated at the bottom of the evaporator 500, and frost on the evaporator 500 can be completely removed by the heating wire 503, thereby ensuring the heat exchange performance of the evaporator 500.
In some embodiments, the evaporator 500 of the refrigerator 100 according to the embodiment of the present invention is disposed in a W-shape in the cooling chamber 150, and has three bending structures 550 in the left-right direction, including a first bending section 510, a second bending section 520, a third bending section 530, and a fourth bending section 540 formed in sequence from left to right. The evaporator 500 of the embodiment of the present invention may be formed by bending a rectangular evaporator, or may be formed by welding two "V" shaped evaporators.

The first bent section 510 and the fourth bent section 540 of the evaporator 500 of the refrigerator 100 according to the embodiment of the present invention are each provided to be bent upward, near the side return air inlet 149. Fig. 4 is a schematic view showing a flow direction of return air when an evaporator of a conventional refrigerator is rectangular. When the rectangular evaporator is used, the fins located in the end plate area of the evaporator are small in passing air quantity due to resistance, return air needs to pass through a 90-degree folded angle twice when passing through the rectangular evaporator, air pressure loss is large, and the overall heat exchange efficiency of the evaporator is greatly reduced. Fig. 5 is a schematic cross-sectional view taken along a sectional line a-a in fig. 1. The evaporator 500 of the embodiment of the invention is bent upwards at the part close to the side return air inlet 149, so that the evaporator 500 and the side return air inlet 149 form an angle and are close to each other, the resistance of the side return air flow flowing over the evaporator 500 is reduced, the side return air quantity is increased, and the heat exchange efficiency of the evaporator 500 is improved. In some embodiments, the first bend 510 is at an angle of 110 ° -140 ° to the second bend 520; the angle between the second bending section 520 and the third bending section 530 is 120-150 degrees; the angle between the third bending section 530 and the fourth bending section 540 is 110-140 deg. According to the refrigerator 100 provided by the embodiment of the invention, the evaporator 500 is designed to be W-shaped integrally and is provided with the three bending structures 550, compared with a rectangular evaporator, the length of a pipeline is increased by 10% -15%, the area of fins is increased by 8% -12%, the heat exchange performance of the evaporator 500 is improved, and the energy consumption of the refrigerator 100 is reduced.

The first fan 701 and the second fan 702 are configured to cause the flow of cooling air to the freezer compartment either separately or simultaneously. The return air flow of the cold storage room and the return air flow of the freezing room flowing through the evaporator 500 radially flow to the first fan 701 and the second fan 702 and then enter the freezing air supply duct 142 at the rear ends of the first fan 701 and the second fan 702, a second 90-degree bending angle is avoided, the fluid resistance is small, the return air quantity is large, and therefore the heat exchange efficiency of the evaporator 500 is improved. The freezing air supply duct 142 extends upward from the cooling chamber 150 along the back of the freezing chamber to the boundary between the freezing chamber and the refrigerating chamber, a refrigerating air supply duct 141 is provided at the back of the refrigerating chamber, and a refrigerating damper 143 is provided at the intersection between the freezing air supply duct 142 and the refrigerating air supply duct 141.
