The temperature in the refrigerated space is typically in the range of-22 ℃ to-14 ℃. The temperature-changing space can be adjusted to-18 ℃ to 8 ℃ at will. The optimum storage temperatures for different types of items are different and the locations suitable for storage are different, for example, fruit and vegetable food is suitable for storage in the refrigerated space 121 and meat food is suitable for storage in the refrigerated space.

Those skilled in the art will recognize that the refrigerator 100 of the present embodiment may further include an evaporator 101, a blower fan 104, a compressor (not shown), a condenser 500, a throttling element (not shown), and the like. The evaporator 101 is connected to the compressor, the condenser 500, and the throttle element via refrigerant lines, and constitutes a refrigeration cycle.

In particular, the refrigerator according to the embodiment of the present invention may further include a drain pipe 400 and a water tray 300. Wherein, the drain pipe 400 extends vertically downwards from the bottom of the first inner container for leading out the liquid water in the first inner container. The drip pan 300 is located below the first inner container and is used for receiving liquid water flowing out from the bottom of the drainage pipe 400. As shown in fig. 6, an engagement tray 401 at the upper portion of the drain pipe 400 is used to engage with the first inner container 130.

The utility model discloses with the vertical setting of drain pipe 400 for hydroenergy in the first inner bag 130 is discharged smoothly enough, also more does benefit to impurity such as screw, ice-cube that probably contain in it and flows downwards. Meanwhile, the drain pipe 400 is vertically arranged to minimize the length thereof, which is also beneficial to the drainage of water and impurities.

The condenser 500 of the refrigerator is horizontally arranged below the first inner container 130, and the water receiving tray 300 is positioned right above the condenser 500, so that the water receiving tray 300 absorbs heat emitted by the condenser 500 to facilitate evaporation of liquid water therein.

As shown in fig. 2 and 3, the refrigerator 100 further includes a bottom compartment 200. The bottom bin 200 is located below the first inner container 130. The rear portion of the top wall of the bottom compartment 200 is higher than the front portion so that the rear space thereof is higher and the front space thereof is lower. The compressor of the refrigerator 100 is disposed in the rear space of the bottom compartment 200. The drip pan 300 is located in the front space of the bottom bin 200, and the drain pipe 400 extends into the bottom bin 200 through the opening of the top wall of the bottom bin 200.

More specifically, the bottom wall of the bottom bin 200 comprises a front bottom plate 204 and a rear bottom plate 202 which are arranged at intervals in front and back, and the interval between the two is used for communicating the internal space of the bottom bin 200 with the space below the bottom bin 200. The drip pan 300 is mounted on the upper surface of the front base plate 204, and the compressor is mounted on the upper surface of the rear base plate 202. The condenser 500 is disposed against the lower surface of the front base plate 204.

The two lateral side walls 203 of the bottom bin 200 are respectively provided with a vent 206 for communicating the inner space and the outer space of the bottom bin 200.

As shown in fig. 5, since the drip tray 300 is mounted on the upper surface of the front bottom plate 204, air flows into the bottom bin 200 from the two ventilation openings 206 to cool the compressor, and then flows toward the drip tray 300 to promote evaporation of liquid water. The rear part of the bottom wall of the water receiving tray 300 is gradually inclined upwards from front to back to form a slope surface 301, so that the airflow coming from the compressor is guided to flow to the bottom of the water receiving tray 300 to heat the bottom of the water receiving tray 300, and the water in the water receiving tray 300 is favorably evaporated by absorbing heat.

As shown in fig. 7, since the condenser 500 is located below the front floor 204, the air flow entering the bottom compartment 200 from the ventilation opening 206 flows to the condenser 500 through the space (the area marked with the width a in fig. 7) between the front floor 204 and the rear floor 202, so as to cool the condenser 500. Fig. 5 and 7 show the air flow direction by arrows. A fan may be provided in the bottom compartment 200 to facilitate the air flow process described above.

halves

202a, 202b by a bar 600. The condenser 500 is divided into two

halves

500a, 500b by a barrier strip 600. A compressor is mounted on half 202a of front base plate 204. Because the temperature of the air flow (left side in the figure) after passing through the compressor is relatively high, the temperature of the air flow (left side in the figure) which does not pass through the compressor is relatively low. Thus, half 500a of condenser 500 on the same side as the compressor is made to have less total heat exchange capacity than half 500 b. This enables more uniform heat dissipation to be achieved for both halves of the condenser 500.

As shown in fig. 2, the bottom wall of the first inner container 130 is formed in a funnel shape extending gradually downward from the periphery toward a central water collecting point 130p, and a drain pipe 400 is connected to the central water collecting point 130 p. The central water collecting point 130p is located in the front half region of the bottom of the first inner container 130 such that the rear portion thereof is positioned higher, facilitating the accommodation of the rear portion of the bottom bin 200.

As shown in fig. 5 and 6, the drip tray 300 is provided with an overflow pipe 320, the bottom end of the overflow pipe 320 is connected to the surface of the drip tray 300, and the upper end is open. The lower end of the drainage pipe 400 is inserted into the overflow pipe 320 so as to overflow from the top end of the overflow pipe 320 after the liquid water fills the overflow pipe 320, so as to seal the lower end of the drainage pipe 400 with the liquid water, i.e., to form a water seal. The leakage of the cooling energy generated at the bottom end of the drain pipe 400 when the drain pipe does not drain water is prevented.

The overflow pipe 320 has a notch 321 at the rear of the upper edge thereof so that the drain pipe 400 is separated from the overflow pipe 320 through the notch 321 when the drip tray 300 is moved forward. Further, both lateral sides of the bottom end periphery of the drain pipe 400 are respectively provided with arc-shaped flanges 410 protruding downward to facilitate the detachment of the drain pipe 400 from the overflow pipe 320.

In some embodiments, the refrigerator 100 further includes a top cover 103 configured to partition the first inner container 130 located at the lowermost portion into a storage space 132 located at an upper portion and a cooling space located at a lower portion, in which the evaporator 101 is horizontally disposed.

The front side of the first inner container 130 may be provided with two door bodies (not shown) that are split to open and close two regions partitioned by the vertical beam 150, respectively.

More particularly, as shown in fig. 14 to 16, the return air frame 1021 includes a first flow guiding inclined section 1021a extending from the upper end of the front wall surface of the return air frame 1021 to the upper rear, and a second flow guiding inclined section 1021c extending from the front wall of the return air frame 1021 to the lower rear; the air return rear cover 1022 includes a third inclined flow guide section 1022a extending from rear to front downward, a fourth inclined flow guide section 1022b extending from the lower end of the third inclined flow guide section 1022a to front downward, a fifth inclined flow guide section 1022c extending from the front end of the fourth inclined flow guide section 1022b to rear downward, and a sixth inclined flow guide section 1022d extending from the lower end of the fifth inclined flow guide section 1022c to rear downward.

Referring to fig. 13, the first oblique flow guiding section 1021a, the third oblique flow guiding section 1022a and the fourth oblique flow guiding section 1022b define a first return air duct (not numbered) located behind the first front return air inlet 102b, and the third oblique flow guiding section 1022a is formed with a plurality of second openings 102d distributed in sequence in a transverse direction. The return air entering from the first front return air inlet 102b enters the cooling space through the first return air duct and the second opening 102d, and enters the evaporator 101 from the upper section of the evaporator 101 to exchange heat with the evaporator 101. The second flow guiding inclined section 1021c and the sixth flow guiding inclined section 1022d define a second return air duct (not numbered) located behind the second front return air inlet 102 a. The return air introduced from the second front return air inlet 102a enters the cooling space through the second return air duct, and enters the evaporator 101 from the lower section of the evaporator 101 to exchange heat with the evaporator 101.

As shown in fig. 16, the dashed arrows in fig. 16 schematically represent the return air flow path. The return air enters the cooling space through the upper return air duct and the lower return air duct, so that the return air more uniformly passes through the evaporator 101, and the heat exchange efficiency is improved. The design of the inclined sections of the return air frame 1021 and the design of the inclined sections of the return air rear cover 1022 guide the liquid water formed in the return air cover 102 for easy drainage.

As shown in fig. 14, the second openings 102d are vertical bars, and the plurality of second openings 102d are distributed in the transverse direction in sequence, and disperse the return air so that the return air enters the upper section of the evaporator 101 more uniformly.

The sixth guide slope 1022d may be formed with a plurality of third openings (not shown) sequentially distributed in the lateral direction, and the return air passing through the second return air passage is divided by each of the third openings and then introduced into the cooling space, so that the return air is introduced into the lower section of the evaporator 101 more uniformly.

The sixth oblique guiding section 1022d may form a mounting portion (not numbered), as shown in fig. 14, the sixth oblique guiding section 1022d forms two mounting portions laterally spaced apart from each other, and correspondingly, the second oblique guiding section 1021c of the return air frame 1021 forms a matching portion matching with the corresponding mounting portion, so as to assemble the return air frame 1021 and the return air rear cover 1022.

As shown in fig. 10, and referring to fig. 14 and 16, the lower surface of the top cover 103 is spaced apart from the upper surface of the evaporator 101, and the front end of the top cover 103 is located behind and above the front end of the evaporator 101, that is, the top cover 103 does not completely shield the upper surface of the evaporator 101, and the front section of the upper surface of the evaporator 101 is not shielded by the top cover 103.

The return air rear cover 1022 further includes a shielding portion (referred to as a first shielding portion 1022e) extending from the third flow guiding inclined section 1022a to the front end of the top cover 103 toward the rear and upward direction, the first shielding portion 1022e is configured to shield a section of the upper surface of the evaporator 101 that is not shielded by the top cover 103, and the first shielding portion 1022e is spaced from the upper surface of the evaporator 101 to form an airflow bypass communicating with the second opening 102d, and at least part of the return air entering through the second opening 102d can enter the evaporator 101 from above the evaporator 101 through the airflow bypass. The space between the top cover 103 and the upper surface of the evaporator 101 is filled with a wind-shielding foam, that is, the rear of the airflow bypass is filled with a wind-shielding foam, so that the return air passing through the airflow bypass flows into the evaporator 101. Therefore, even when the front end face of the evaporator 101 is frosted, return air still enters the evaporator 101 to exchange heat with the evaporator 101, the refrigeration effect of the evaporator 101 is guaranteed, the problem that the refrigeration effect of the existing refrigerator 100 is reduced due to the fact that the front end face of the evaporator 101 is frosted is solved, and the refrigeration performance of the refrigerator 100 is improved.

As shown in fig. 14 and 16, the return air frame 1021 further includes a second shielding portion 1021b bent and extended from the first flow guiding inclined section 1021a to the top cover 103, and the second shielding portion 1021b completely shields the first shielding portion 1022e, so as to maintain the aesthetic appearance of the return air cover 102.

Further, referring to fig. 16, a joint C between the fourth oblique flow guiding section 1022b and the fifth oblique flow guiding section 1022C is located right below the first oblique flow guiding section 1021a, and the liquid water formed in the return air frame 1021 drops down along the inclined plane of the first oblique flow guiding section 1021a to the joint C between the fourth oblique flow guiding section 1022b and the fifth oblique flow guiding section 1022C right below (i.e., a corner between the fourth oblique flow guiding section 1022b and the fifth oblique flow guiding section 1022C), and then drops down along the inclined plane of the fifth oblique flow guiding section 1022C to the second oblique flow guiding section 1021C, and further flows below the evaporator 101. The evaporator 101 generally has a water receiving area formed with a drain opening below the water receiving area to discharge liquid water. Therefore, liquid water formed on the air return cover 102 is guided and discharged, water drop sound which can be sensed by human ears is avoided, and the use experience of a user is improved.

The bottom wall of the first liner 130 may be formed with a water receiving section located below the evaporator 101, a projection of the water receiving section on a vertical plane parallel to the side wall of the first liner 130 includes a front guiding inclined section 133 located at the front side and extending downward and rearward, a horizontal straight section 134 horizontally extending rearward from the front guiding inclined section 133, and a rear guiding inclined section 135 horizontally extending upward and rearward from the rear end of the horizontal straight section 134, and the horizontal straight section 134 is formed with a water discharge port (not shown). The liquid water formed on the return air cover 102 is guided by the inclined sections of the return air frame 1021 and the return air rear cover 1022, flows along the front guide inclined section 133 to the horizontal straight section 134, and is finally discharged through the water outlet. The liquid water on the evaporator 101 flows to the horizontal straight section 134 along the front diversion inclined section 133 and the rear diversion inclined section 135 respectively, and is discharged from the water discharge port.
