Fig. 1 illustrates a schematic front view of a tank assembly according to an embodiment of the present utility model, fig. 2 illustrates a schematic cross-sectional structure along a section line A-A in fig. 1, fig. 3 illustrates a schematic enlarged partial structure at a in fig. 2, and as shown in fig. 1 to 3, a first aspect of the present utility model provides a tank assembly including a tank body 600 and a defrosting assembly 700. The cabinet body 600 has a compartment 610 therein, and a guide rail is provided at a sidewall of the compartment 610. A defrost assembly 700 is disposed within the compartment 610, the defrost assembly 700 being adapted to remove condensation or frost from the rails.

According to the box liner assembly provided by the embodiment of the application, the condensed water or frost layer on the guide rail is removed through the defrosting assembly 700, so that the phenomenon that a drawer is pulled unsmoothly due to frozen ice on the guide rail is avoided, and the convenience of a user in using the refrigerator is improved.

It will be appreciated that the liner assembly includes an air duct assembly 612 disposed within the compartment 610. The defrost assembly 700 includes a deflector 710, the deflector 710 being in communication with the air duct assembly, the deflector 710 being adapted to direct the air flow within the air duct assembly to the rail to remove condensation water from the surface of the rail. The air duct assembly is used to generate an air flow for heat exchange within the compartment 610 to effect cooling. By communicating the baffle 710 with the air duct assembly, the air flow generated by the air duct assembly can be diverted to the guide rail by the baffle 710. At the guide rail, the water vapor generated by the heat exchange between the cold air in the compartment 610 and the hot air outside the compartment 610 is carried away by the air flow guided by the guide member 710, so that the water vapor accumulated by the guide rail is prevented from increasing gradually, and is condensed into ice on the surface of the guide rail, and the drawer on the guide rail is prevented from opening or closing.

It is understood that the defrosting assembly 700 includes a plurality of guide members 710, and the plurality of guide members 710 are arranged in one-to-one correspondence with the guide rails. The air flow guide 710 guides the air flow in the air duct assembly to the corresponding guide rail, and the air flow takes away the water vapor of the corresponding guide rail. Because the guide rails at all positions are provided with the corresponding guide pieces 710, the water vapor of the guide rails at all positions can be taken away, and the situation that the missing water vapor freezes at all positions and influences the opening or closing of the drawer is avoided. Of course, a plurality of corresponding guide members 710 may be disposed on the same guide rail, so as to increase the airflow flow of the guide rail at the same position, and enhance the effect of taking away water vapor by the airflow.

Fig. 4 illustrates a schematic perspective structure of a back plate provided by the embodiment of the present application, as shown in fig. 4, an air duct assembly is disposed on a back plate 611 of a chamber 610, an air outlet 711 of a flow guiding member 710 faces a corresponding guide rail, and an acute included angle is formed between an inner wall of the air outlet 711 and the back plate 611, i.e. an included angle a in the figure. The air duct assembly creates an air flow in the region of the back plate 611, which flows out of the air outlet 711. Since the air outlet 711 is oriented toward the rail, air flows from the air outlet 711 to the rail to carry away moisture from the rail. Because the inner wall of the air outlet 711 forms an acute angle with the back plate 611, the air outlet 711 can change the flow direction of the air flow in the back plate 611 area, so that the air flow can accurately flow to the guide rail, and the water vapor of the guide rail is effectively taken away.

It will be appreciated that the acute included angle between the inner wall of the air outlet 711 and the backplate 611 is in the range of 10 ° -30 °. The range of the acute angle can be adjusted according to actual conditions. The airflow velocity can be increased by reducing the angle of the acute included angle, and the power of the airflow for taking away water vapor is enhanced. The accuracy of the air outlet 711 towards the guide rail can be improved by increasing the angle of the acute angle, and water vapor can be accurately taken away.

It will be appreciated that the compartment 610 is a freezer compartment, one side of the freezer compartment is provided with a variable temperature compartment, and a return air passage is provided between the freezer compartment and the variable temperature compartment, the return air passage being in communication with the air duct assembly. The air duct component generates low-temperature air flow, the low-temperature air flow enters the freezing compartment for heat exchange to be changed into high-temperature air flow, the high-temperature air flow enters the return air duct and returns to the air duct component through the return air duct, and heat exchange circulation is completed. Similarly, the air duct component generates low-temperature air flow, the low-temperature air flow enters the temperature-changing chamber to be subjected to heat exchange to be changed into high-temperature air flow, and the high-temperature air flow enters the return air duct and returns to the air duct component through the return air duct, so that heat exchange circulation is completed. On one hand, a temperature-changing compartment is increased by arranging a return air duct, so that the versatility of the box liner assembly is enhanced; on the other hand, the structure of the box liner assembly is simplified by sharing the return air duct through the freezing compartment and the variable-temperature compartment.

It will be appreciated that the side walls of the temperature change compartment have rails adapted to secure the rails, the temperature change compartment being provided with a defrost assembly 700, the defrost assembly 700 being adapted to remove condensation or frost from the rails of the temperature change compartment.

Fig. 5 illustrates a schematic perspective view of a liner assembly according to an embodiment of the present application, and as shown in fig. 5, the liner assembly further includes an air duct cover 800, a cover mounting opening communicating with a return air channel is provided near a side wall of the temperature changing chamber, the air duct cover 800 covers the cover mounting opening, and the air duct cover 800 is detachably connected to the liner body 600. The guide rail is arranged on one side of the air duct cover plate, which faces the freezing compartment. Because parts such as evaporimeter are located the return air wind channel, when the evaporimeter need maintenance change, can accomplish maintenance change through the apron installing port, need not to demolish whole case courage subassembly. The side wall is the side wall of the freezing chamber, namely, a cover plate mounting opening is arranged on the side wall of the freezing chamber.

The flow guide 710 of the temperature changing chamber is communicated with the air duct assembly, the flow guide 710 of the temperature changing chamber guides the air flow in the air duct assembly to the guide rail of the temperature changing chamber so as to take away the condensate water on the surface of the guide rail of the temperature changing chamber, and the air flow mixed with the condensate water enters the return air duct and finally returns to the air duct assembly. The guide 710 of the freezing compartment is communicated with the air duct assembly, the guide 710 of the freezing compartment guides the air flow in the air duct assembly to the guide rail of the freezing compartment so as to take away the condensed water on the surface of the guide rail of the freezing compartment, and the air flow mixed with the condensed water enters the return air duct and finally returns to the air duct assembly. Namely, the return air duct and the air duct of the box liner assembly are matched with the guide piece 710 of the temperature changing chamber at the same time to remove the condensation water or frost layer of the guide rail in the temperature changing chamber, and are matched with the guide piece 710 of the freezing chamber at the same time to remove the condensation water or frost layer of the guide rail in the freezing chamber.

It is understood that the side of the air duct cover plate facing the freezing compartment is provided with a guide rail support member, and the guide rail is detachably connected with the guide rail support member.

Fig. 6 illustrates a schematic front view of a duct cover according to an embodiment of the present application, fig. 7 illustrates a schematic perspective view of a duct cover according to an embodiment of the present application, and fig. 8 illustrates a schematic partial enlarged view of a portion B in fig. 7, as shown in fig. 6 to 8, the duct cover includes a cover body 100 and a rail support 200. The guide rail support 200 is arranged at one side of the cover plate body 100 facing the compartment, at least one group of first guide inclined planes 210 connected with the cover plate body 100 are arranged at the upper part of the guide rail support 200, guide holes 213 are arranged on the first guide inclined planes 210, and the height of the guide holes is smaller than that of at least part of the first guide inclined planes 210; the guide rail support 200 or the cover plate body 100 is provided at one side facing the chamber with a flow passage 214 communicating with the flow guide hole to guide the condensation water flowing into the flow guide hole to the lower side of the guide rail support 200.

Because the height of the diversion hole is smaller than that of at least part of the first diversion inclined plane 210, when condensation water is generated by cold and hot junction of the surface of the air duct cover plate, the condensation water under the action of gravity flows into the diversion hole along the first diversion inclined plane 210. The condensed water flowing into the guide hole is guided by the flow passage to the lower side of the rail supporter 200. Because the first diversion inclined plane 210 is used for diversion of the condensation water, the phenomenon that the drawer cannot be pulled out due to condensation and frost formation of the condensation water generated by cold and hot junction of the surface of the air duct cover plate or the condensation water flows downwards into the storage space inside the refrigeration equipment to influence the refrigeration effect of the refrigeration equipment is avoided.

It should be noted that the rail support 200 is used to support the drawer and guide the drawer of the refrigeration equipment to slide horizontally along the rail support 200 so as to open or close the drawer. Accordingly, the rail supporter 200 is disposed in the horizontal direction.

It is understood that the compartment is a freezing compartment, the guide rail support 200 is disposed on a side of the cover plate body 100 facing the freezing compartment, and at least one set of first guide inclined planes 210 connected to the cover plate body 100 is disposed on an upper portion of the guide rail support 200. The first diversion inclined plane 210 is provided with a diversion hole, and the height of the diversion hole is smaller than that of at least part of the first diversion inclined plane 210. The guide rail support 200 or the cover plate body 100 is provided at one side facing the freezing compartment with a flow passage communicating with the flow guide hole to guide the condensation water flowing into the flow guide hole to the lower side of the guide rail support 200. Of course, the chamber may also be a temperature-changing chamber, so as to drain the condensation water generated at the cold-hot junction of the surface of the air duct cover plate in the temperature-changing chamber to the lower part of the guide rail support 200.

It is understood that the first diversion ramp 210 includes a first ramp 211 and a second ramp 212. The first inclined plane 211 and the second inclined plane 212 are connected with the cover plate body 100, the first inclined plane 211 and the second inclined plane 212 are arranged on two sides of the diversion hole along the width direction of the cover plate body 100, and the first inclined plane 211 and the second inclined plane 212 incline downwards towards the diversion hole. The condensation water generated by cold and hot junction of the surface of the air duct cover plate falls into the first inclined plane 211 or the second inclined plane 212 under the action of gravity, and the condensation water is guided into the diversion hole by the first inclined plane 211 or the second inclined plane 212 as the first inclined plane 211 and the second inclined plane 212 incline downwards towards the diversion hole.

It is understood that the first inclined surface 211 and the second inclined surface 212 are symmetrically disposed about the flow guiding hole. By disposing the first inclined surface 211 and the second inclined surface 212 at both sides of the guide hole, the area of the first guide inclined surface 210 in the width direction of the cap body 100 is increased so that the first guide inclined surface 210 can receive more range of condensed water.

It is understood that the height of the diversion holes is less than the height of the first inclined plane 211 and the second inclined plane 212. When the first inclined plane 211 and the second inclined plane 212 are inclined downwards towards the diversion hole, and the first inclined plane 211 and the second inclined plane 212 are symmetrically arranged relative to the diversion hole, the first inclined plane 211 and the second inclined plane 212 are arranged in a V shape, and the diversion hole is positioned at the lowest point of the V shape.

It can be appreciated that the first diversion slope 210 further includes a third slope 220, the third slope 220 is connected to the first slope 211 and the second slope 212, the third slope 220 is located on a side of the first slope 211 and the second slope 212 away from the cover plate body 100, and the third slope 220 is inclined downward toward the diversion hole. Because the third inclined plane 220 is located at one side of the first inclined plane 211 and the second inclined plane 212 away from the cover plate body 100, the third inclined plane 220 can play a role of a flange, so that condensation water on the surfaces of the first inclined plane 211 and the second inclined plane 212 is prevented from moving towards a direction away from the cover plate body 100 under the action of gravity and falling into the outside of the diversion hole, and then is condensed into frost or stays in the storage space of the compartment. When the condensation water is on the surface of the third inclined plane 220, the third inclined plane 220 is inclined downwards towards the diversion hole, so that the third inclined plane 220 can divert the condensation water into the diversion hole, and the diversion effect of the first diversion inclined plane 210 is improved.

It can be appreciated that the guide rail support 200 is provided with a plurality of sets of first guide inclined planes 210, and the plurality of sets of first guide inclined planes 210 are sequentially arranged along the width direction of the cover plate body 100; of the adjacent two first diversion slopes 210, the second slope 212 of one first diversion slope 210 is connected with the first slope 211 of the other first diversion slope 210. Compared with the arrangement of only one group of first diversion inclined planes 210, the diversion range of the air duct cover plate can be increased by the plurality of groups of first diversion inclined planes 210, more condensate water on the air duct cover plate is diverted to diversion holes, and the diversion effect is improved. Since the first inclined plane 211 and the second inclined plane 212 are inclined downward toward the diversion hole, the first inclined plane 211 and the second inclined plane 212 of the same group are symmetrically arranged with respect to the diversion hole, and when the second inclined plane 212 of one first diversion inclined plane 210 is connected with the first inclined plane 211 of the other first diversion inclined plane 210, the second inclined plane 212 of one first diversion inclined plane 210 is arranged in an inverted V shape with the first inclined plane 211 of the other first diversion inclined plane 210.

It will be appreciated that the flow channel is formed at the side of the cover plate body 100 facing the compartment, and the bottom of the rail support 200 is provided with a drain outlet 230 communicating with the flow channel. The condensation water flowing into the flow path from the diversion hole is discharged from the water discharge outlet 230 under the diversion of the flow path. Through the cooperation of the flow passage and the water outlet 230, the condensation water can be guaranteed to be drained to the lower side of the guide rail support 200, the condensation water is prevented from condensing into frost at the guide rail support 200, and normal use of the guide rail support 200 is not affected.

It can be understood that the duct cover includes the first rail supporter 300 and the second rail supporter 400, and the first rail supporter 300 and the second rail supporter 400 are spaced apart in the up-down direction, and the water discharge ports 230 of the first rail supporter 300 are in one-to-one correspondence with the water guide holes of the second rail supporter 400. After the condensation water is discharged from the water discharge opening 230 of the first rail support 300, the condensation water can enter the water guide hole of the second rail support 400 under the action of gravity because the water discharge opening 230 of the first rail support 300 corresponds to the water guide hole of the second rail support 400 one by one.

It should be noted that, the first rail support 300 and the second rail support 400 are both provided with the first diversion slope 210, and the structures of the first rail support 300 and the second rail support 400 are identical, and the difference is that the setting positions are different.

In one aspect, by providing the first rail support 300 and the second rail support 400 in the up-down direction of the duct cover, the drainage range of the condensation water on the surface of the duct cover is increased. When the condensation water slides down along the surface of the air duct cover plate, the condensation water moves inevitably in a direction away from the cover plate body 100 along with the increase of the sliding distance, and by arranging the first guide rail support 300 and the second guide rail support 400, the condensation water falls into the first guide inclined plane 210 of the first guide rail support 300 or the first guide inclined plane 210 of the second guide rail support 400 before being separated from the cover plate body 100, so as to avoid the condensation water falling into the storage space of the compartment.

On the other hand, the number of rail supports 200 corresponds to the number of drawers. The first rail supporter 300 is disposed corresponding to the first drawer, and the second rail supporter 400 is disposed corresponding to the second drawer. By providing the first guide slope 210 at the upper portion of the first rail supporter 300, the first drawer is prevented from being pulled difficult due to frost condensation at the rail. By providing the first guide inclined surface 210 at the upper portion of the second rail support 400, the second drawer is prevented from being pulled difficult due to frost condensation at the rail.

It will be appreciated that the drain opening 230 of the first rail support 300 is in the same vertical line as the deflector hole of the second rail support 400. Since the movement trace of the condensation water under the action of gravity is a vertical straight line, the drain outlet 230 of the first rail support 300 and the guide hole of the second rail support 400 are disposed on the same vertical straight line, so that the condensation water can directly flow into the guide hole of the second rail support 400.

Specifically, the first rail supporter 300 and the second rail supporter 400 are each provided with a guide hole and a drain opening 230. The condensation water at the upper portion of the first rail supporter 300 enters the guide hole under the guide of the first guide slope 210 and flows out of the drain outlet 230 of the first rail supporter 300 through the flow passage. The condensation water flowing out of the water outlet 230 of the first rail support 300 slides down along the surface of the cover plate body 100 and finally directly enters the guide hole of the second rail support 400, or reaches the first guide inclined plane 210 of the second rail support 400 first and then enters the guide hole of the second rail support 400 under the guiding action of the first guide inclined plane 210.

It can be appreciated that the air duct cover plate further includes a flow guiding assembly 500, the flow guiding assembly 500 includes a plurality of first flow guiding members 510, the plurality of first flow guiding members 510 are disposed on one side of the cover plate body 100 facing the compartment and located between the first guide rail supporting members 300 and the second guide rail supporting members 400, the plurality of first flow guiding members 510 are disposed at intervals along the width direction of the cover plate body 100, and the first flow guiding members 510 are disposed obliquely downward toward the corresponding flow guiding holes.

After the condensation water flows out from the drain outlet 230 of the first rail support 300, the condensation water is located between the first rail support 300 and the second rail support 400. Since the distance between the first rail support 300 and the second rail support 400 is long, the condensed water will inevitably move toward a side far from the cover plate body 100 under the influence of the external air flow, and the flow guiding effect of the first flow guiding slope 210 is weakened. By providing the first guide 510, when the condensation water flows out from the water outlet 230 of the first guide rail support 300, the condensation water reaches the first guide 510 under the action of gravity, and enters the corresponding guide hole under the guide of the first guide 510.

In addition, the surface of the cover plate body 100 between the first rail support 300 and the second rail support 400 may generate condensation water due to cold and hot junction, and the generated condensation water enters the corresponding guide hole under the guide of the first guide 510.

It is understood that some of the plurality of first baffle members 510 are inclined downwardly toward the chamber opening and others of the plurality of first baffle members 510 are inclined downwardly away from the chamber opening. That is, the plurality of first deflectors 510 are symmetrically disposed about the vertical central axis of the cover body 100, so that the condensation water is collected at the central position of the cover body 100 under the drainage action of the first deflectors 510.

It can be appreciated that the duct cover further includes a second guide 520, where the second guide 520 is disposed on a side of the cover body 100 facing the compartment and below the second rail support 400. The second guiding member 520 is provided with a second guiding inclined plane 521 at an upper portion thereof, and the cover plate body 100 is provided with a guiding through hole (not shown) penetrating through the cover plate body 100, wherein the guiding through hole is located at a side of the second guiding inclined plane 521 near the cover plate body 100, and a height of the guiding through hole is smaller than a height of the second guiding inclined plane 521. When the condensation water is discharged from the drain outlet 230 of the second rail support 400, it reaches the second diversion slope 521 by gravity. The condensed water is guided into the guide through hole through the second guide inclined plane 521.

It can be understood that the side of the cover plate body away from the compartment is provided with an air duct, and a water receiving disc is arranged in the air duct.

After the condensation water is discharged from the drain outlet 230 of the second rail support 400, the condensation water reaches the fourth inclined plane 522 or the fifth inclined plane 523, and enters the guide through hole under the guide effect of the fourth inclined plane 522 or the fifth inclined plane 523.

It is understood that the fourth inclined surface 522 and the fifth inclined surface 523 are symmetrically disposed about the flow guiding through hole. By disposing the first inclined surface 211 and the second inclined surface 212 at both sides of the guide hole, the area of the second guide inclined surface 521 in the width direction of the cover plate body 100 is increased so that the second guide inclined surface 521 can receive more range of condensed water.

It is understood that the height of the flow guiding through hole is smaller than the height of the fourth inclined surface 522 and the fifth inclined surface 523. When the fourth inclined plane 522 and the fifth inclined plane 523 both incline downward toward the flow guiding hole, and the fourth inclined plane 522 and the fifth inclined plane 523 are symmetrically disposed about the flow guiding through hole, the fourth inclined plane 522 and the fifth inclined plane 523 are disposed in a V shape, and the flow guiding through hole is located at the lowest point of the V shape.
