Detailed Description

The utility model providesbase:Sub>A refrigerator, figure 1 is according to the utility model disclosesbase:Sub>A schematic structure chart of refrigerator of an embodiment, figure 2 is the schematic cross-sectional view of cutting along cutting line A-A in figure 1, and figure 3 is according to the utility model disclosesbase:Sub>A refrigerator part structure schematic exploded view of an embodiment. Referring to fig. 1 to 3, a refrigerator 1 of the present invention includes a cabinet 10, a cover plate 30, and an evaporator 20.

The case 10 has an inner container 11 at a lower portion thereof. The cover 30 is provided in the inner container 11, and partitions an inner space of the inner container 11 into an upper storage chamber 111 and a lower cooling chamber 112. The evaporator 20 is provided in the cooling chamber 112 and configured to supply cooling energy to the storage compartment 111. That is, the evaporator 20 is a bottom-mounted evaporator provided at the bottom of the cabinet 10, and the cooling chamber 112 is a bottom-mounted cooling chamber provided at the bottom of the cabinet 10.

Fig. 4 is a schematic structural view of a cover plate according to an embodiment of the present invention. The cover plate 30 includes a transverse section 31 extending from the rear to the front and a vertical section 32 extending from the front end of the transverse section 31 to the bottom wall of the liner 11 obliquely from the top to the bottom, and the cooling chamber 112 is located at the rear side of the vertical section 32. The vertical section 32 is provided with a rear return air inlet 321 for returning the return air flow from the storage compartment 111 to the cooling compartment 112.

The utility model discloses a refrigerator 1 has the bottom evaporimeter 20 of putting and the bottom cooling chamber 112 of putting, a apron 30 that is used for separating the cooling chamber 112 of putting at the bottom and storing room 111 not only has the horizontal district section 31 by backward preceding extension, but also has the vertical district section 32 that extends to inner bag 11 diapire forward from last down slope by the front end of horizontal district section 31, back return air inlet 321 has been seted up on the vertical district section 32, therefore, the comdenstion water of back return air inlet 321 department flows to inner bag 11 diapire along vertical district section 32 in time under self action of gravity, and finally flow to the water collector or other water collecting structure of inner bag 11 diapire, consequently, back return air inlet 321 is difficult for producing freezing or frosting, the problem that back return 321 department produced the frost stifled has been avoided.

The existing refrigerator with the bottom evaporator and the bottom cooling chamber also adopts the cover plate to separate the cooling chamber from the storage chamber, however, the cover plate in the prior art only has a transverse section and no vertical section, and a return air cover is required to be arranged at the front side of the cover plate to isolate the cooling chamber from the sight of a user. When the storage room produces condensed water, the condensed water drops on the cover plate or the return air cover. Condensed water dropping on the cover plate drops into the cooling chamber from an assembly gap between the cover plate and the air return cover, and easily drops on the evaporator to cause severe frosting of the evaporator; the condensed water dropping on the air return cover directly flows out of the box body, and the use experience of a user is influenced.

The utility model discloses a apron 30 has horizontal district section 31 and vertical district section 32 simultaneously, is equivalent to horizontal district section 31 and vertical district section 32 and is the integrative piece that level and smooth meets, is favorable to the comdenstion water of drippage in the storing compartment 111 of horizontal district section 31 top to directly flow to the inner bag diapire along the vertical district section 32 that the slope extends, and can not flow out box 10 and influence the user and use experience or drip and cause the serious problem of evaporimeter 20 frosting on evaporimeter 20.

In some embodiments, the number of the rear air inlets 321 is multiple, the multiple rear air inlets 321 are arranged at intervals along the transverse direction, and each rear air inlet 321 is a strip-shaped air inlet extending along the vertical direction. That is, the grills 322 for separating the adjacent two rear air returns 321 each extend vertically in accordance with the flow tendency of the condensed water on the vertical section 32. Therefore, the condensed water hardly stays on the grid bars 322, which is beneficial for the condensed water to flow downwards along the grid bars 322 more quickly, improves the flowing speed of the condensed water, and more effectively avoids the problem of icing or frosting at the rear air return port 321.

Specifically, the width of the rear return air opening 321 is preferably 5mm or less to prevent a child user from inserting a finger.

Fig. 5 is a schematic sectional view of a combination of an inner container, a cover plate and a return air cover according to an embodiment of the present invention, and fig. 6 is a schematic enlarged view of a portion B in fig. 5. Referring to fig. 4-6, in some embodiments, the front side of the vertical section 32 is also provided with a forwardly projecting flow-guiding rib 323. The flow guiding ribs 323 extend obliquely downward or curve downward from the transverse middle of the vertical section 32 to the transverse sides of the vertical section 32. On the one hand, when the condensate water flowing from top to bottom on the vertical section 32 meets the diversion rib 323, the condensate water can flow to the two transverse sides of the vertical section 32 along the diversion rib 323 and then flows to the bottom wall of the inner container 11, the part of the condensate water can not flow through the area, below the diversion rib 323, of the rear air return opening 321, the condensate water amount attached to the rear air return opening 321 is reduced, the icing amount or frosting amount generated at the rear air return opening 321 is reduced, and even the problem of icing or frosting generated at the rear air return opening 321 is avoided. On the other hand, the flow guiding ribs 323 extend downwards from the middle to the two sides, which is not only favorable for the rapid flow of condensed water, but also can ensure that the upper part and the lower part of at least most sections of the flow guiding ribs 323 are positioned in the airflow path of the rear air return inlet 321, i.e. ensure that return air flows pass through the upper part and the lower part of at least most sections of the flow guiding ribs 323, and prevent the local large-area frosting at the positions of the flow guiding ribs 323.

Further, the middle of the flow guiding rib 323 is adjacent to the top of the vertical section 32, and both ends of the flow guiding rib 323 are adjacent to the middle of the vertical section 32 in the vertical direction, so that the flow guiding rib 323 is integrally located at the upper part of the vertical section 32. On one hand, the flow path of the condensed water on the grate bars 322 is shortened as much as possible, thereby reducing the amount of the condensed water attached to the rear air return opening 321 as much as possible; on the other hand, the diversion ribs 323 have enough inclination or bending to enable condensed water to flow down from the diversion ribs 323 as soon as possible, and the problem of frosting or icing at the diversion ribs 323 is avoided.

Fig. 7 is a schematic structural view of the inner container according to an embodiment of the present invention. Referring to fig. 7, it can be understood that the bottom wall of the inner container 11 below the evaporator 20 forms a water pan 113, and a water outlet 114 is opened at the bottom of the water pan 113. Therefore, the condensed water flowing to the drain pan 113 can be discharged from the drain port 114 in time, and does not stay in the cooling chamber to form frost.

To this end, in some embodiments, the flow guiding ribs 323 extend obliquely upward from back to front. Therefore, the condensed water on the flow guiding ribs 323 has a tendency of flowing to the two lateral sides and backwards, even if the amount of the condensed water on the flow guiding ribs 323 is large, the condensed water does not overflow the flow guiding ribs 323 forwards, but flows to the bottom wall of the liner 11 positioned at the rear side of the vertical section 32 along the flow guiding ribs 323 or the grid bars 322, namely flows to the water receiving tray 113, and is convenient for being discharged through the water outlet 114 at the bottom of the water receiving tray 113.

Specifically, the angle between the flow guide ribs 323 and the horizontal plane is preferably greater than 7 °.

In some embodiments, the lid 30 also includes a flange 33 at its edge for mating with the liner 11. Specifically, the flanges 33 may include two side flanges 331 located at both lateral edges of the cover 30 and a bottom flange 332 located at the bottom edge of the cover 30.

Furthermore, gaps are formed between the two transverse ends of the flow guiding rib 323 and the two side flanges 331 located at the two transverse sides of the vertical section 32, so that condensed water flowing down from the flow guiding rib 323 flows downwards to the bottom wall of the liner 11 through the gaps, and condensed water collection cannot be formed.

Further, a bottom flange 332 located below the vertical section 32 extends obliquely upward from the lower end of the vertical section 32 toward the front. Therefore, the condensed water flowing down from the vertical section 32 to the bottom flange 332 flows backwards along the bottom flange 332 instead of forwards along the bottom flange 332, and a part of the condensed water is prevented from flowing out of the tank 10 from the front part of the inner container 11. The condensed water flowing backward along the bottom flange 332 flows toward the bottom wall of the inner container 11 below the evaporator 20, i.e., toward the drip pan 113, so that the condensed water can be discharged through the drainage port 114 in time.

Specifically, the angle between the bottom flange 332 and the horizontal plane is preferably greater than 7 °, which is more favorable for the backward flow of the condensed water.

In some embodiments, the bottom wall of the inner container 11 has a laterally extending and upwardly raised ridge 115, and the bottom flange 332 of the lid panel 30 overlaps over the ridge 115. The ridge 115 can prevent the condensed water from flowing back and forth, and the condensed water on the bottom wall of the liner at the rear side of the vertical section 32 is prevented from flowing to the bottom wall of the liner at the front side of the vertical section 32.

In some embodiments, the bottom wall 116 of the bladder 11, which is located below the evaporator 20 and adjacent to the vertical section 32, extends obliquely downward from front to back, facilitating faster flow of the condensate to the drain opening 114.

Further, the angle at which the vertical section 32 is inclined forward from top to bottom is set such that the vertical section 32 is perpendicular to the bottom wall 116. That is, the vertical section 32 forms an angle of approximately 90 ° with the bottom wall 116 of the inner container below the evaporator 20, so that the vertical section 32 can play a significant role in guiding the return air to the evaporator 20 as much as possible, thereby enabling the evaporator 20 to exchange heat with the return air more sufficiently.

Further, the forward sloping extension of the vertical section 32 also creates a frost containing space between the vertical section 32 and the evaporator 20, facilitating the flow of the return air stream.

In some embodiments, the refrigerator 1 further includes a return air cover 40, and the return air cover 40 is disposed at a front side of the cover plate 30 and has a transverse cover plate 41 extending from a rear direction to a front direction and a vertical cover plate 42 extending downward from a front end of the transverse cover plate 41. The vertical cover plate 42 is provided with a front air return opening 421, and the vertical cover plate 42 and the vertical section 32 of the cover plate 30 are arranged at intervals to define a return air space 50 among the return air cover 40, the vertical section 32 of the cover plate 30, and the bottom wall and two transverse side walls of the inner container 11.

That is, the return air flow in the storage compartment 111 flows into the cooling compartment 112 through the front return air inlet 421 and the rear return air inlet 321 in this order. Since the front return air opening 421 is located at the front side of the bottom of the entire inner container 11, the flow of return air flowing from the storage compartment 111 to the cooling compartment 112 inevitably goes through the reversing process. The return air space 50 provides a buffer space for reversing and stabilizing the flow of the return air, the flow resistance of the return air is small, and the return air flows to the cooling chamber 112 after flowing through the return air space with small flow resistance, so that the flow rate of the return air is prevented from being greatly influenced by reversing. In addition, moisture in the return air flow can be condensed in advance at the front return air inlet 421, the return air space 50 and the rear return air inlet 321, so that moisture condensed on the evaporator 20 is reduced, and the frosting condition of the evaporator 20 is relieved.

It can be understood that, for the refrigerator 1 with a smaller size in the depth direction, the cover plate 30 can be directly used to isolate the storage compartment 111 and the cooling compartment 112 and enable the storage compartment and the cooling compartment to be communicated through the air return opening, and the air return cover 40 is not required to be arranged. For the refrigerator 1 with a large size in the depth direction, the air return cover 40 needs to be arranged on the front side of the cover plate 30, and the purpose of isolating the storage compartment 111 and the cooling compartment 112 and communicating the storage compartment and the cooling compartment through the air return opening can also be met. It can be seen that the utility model discloses a apron 30 has stronger commonality, is applicable to not unidimensional refrigerator, has saved the mould cost.

In addition, the front side of the cover plate is provided with the return air cover, so that the effect of decoration can be achieved, and the appearance of the front part is unified.

In some embodiments, the refrigerator 1 further comprises a drain pipe 61, the drain pipe 61 extending from the cooling chamber 112 to the evaporation pan of the refrigerator 1 for draining the condensed water in the cooling chamber 112 to the evaporation pan.

Fig. 8 is a schematic cross-sectional view of a combination of the inner container, the cover plate and the return air cover according to another embodiment of the present invention. In other embodiments, the bottom wall of the return air space 50 is formed with a water collecting groove 51 recessed downward, so that the condensed water flowing into the return air space 50 from the return air cover 40 and/or the cover plate 30 is collected by the water collecting groove 51, and the user experience is prevented from being affected by the condensed water flowing out from the front side of the inner container 11.

In some embodiments, the bottom wall of the inner container 11 has a ridge portion 115 extending in the lateral direction and protruding upward, the bottom wall of the return air space 50 is located on the front side of the ridge portion 115, and the bottom wall of the cooling compartment 112 is located on the rear side of the ridge portion 115. That is, the ridge portion 115 divides the bottom wall of the inner container 11 into front and rear portions, and since the ridge portion 115 is upwardly protruded, the flow of the condensate water between the front and rear portions, that is, the flow of the condensate water between the return air space 50 and the cooling compartment 112, is prevented.

Further, the cover plate 30 further includes a bottom flange 332 located below the vertical section 32, the bottom flange 332 overlaps the ridge 115, and a front section of the bottom flange 332 extends from the bottom of the vertical section 32 to the front obliquely upward and then bends to extend downward, so that the condensed water flowing down from the vertical section 32 to the bottom flange 332 flows rearward along the bottom flange 332 as much as possible, and thus flows to the water pan 113 at the bottom of the cooling chamber 112, and the condensed water is conveniently discharged through the water outlet 114 in time. When the amount of the condensed water flowing down from the vertical section 32 to the bottom flange 332 is too large, it is inevitable that a part of the condensed water flows down to the front side of the bottom flange 332, and at this time, the condensed water flowing down from the front side of the bottom flange 332 is also collected in the water collecting groove 51 and does not flow out of the inner container 11 forward.

Further, the rear section of the bottom flange 332 extends rearwardly and downwardly from the bottom of the vertical section 32 to direct the condensate to flow more quickly rearwardly.

In some embodiments, an overflow gap is formed between at least a portion of the bottom of the vertical cover plate 42 and the bottom wall of the inner container 11 to allow condensed water on the bottom wall of the inner container 11 located at the front side of the vertical cover plate 42 to flow into the water collecting groove 51 through the overflow gap. The formation of the overflowing gap provides a flowing channel for the backward flowing of the condensed water on the front side of the vertical cover plate 42, so that the flowing resistance of the condensed water is reduced, and the condensed water can flow backward quickly.

In some embodiments, the vertical shroud 42 extends obliquely forward from top to bottom. Therefore, the condensed water dropping on the return hood 40 can flow downwards along the vertical cover plate 42, and then flows backwards into the water collecting groove 51 through the gap between the bottom of the vertical cover plate 42 and the bottom wall of the liner, so that the condensed water is prevented from flowing to the outside of the tank 10 as much as possible.

Further, the inner container bottom walls on the front side and the two transverse sides of the water collecting groove 51 extend downwards towards the water collecting groove 51 in an inclined mode, condensed water dropping on the inner container bottom walls around the water collecting groove 51 is facilitated to collect in the water collecting groove 51 more quickly, and the condensed water collecting efficiency is improved.

In some embodiments, the sidewalls of the water collecting grooves 51 each extend obliquely from top to bottom toward the middle of the water collecting grooves 51 to further guide the condensed water flowing into the water collecting grooves 51 to be collected into the water collecting grooves 51.

In some embodiments, an air duct assembly 70 is further disposed at the rear side of the inner container 11, an air supply duct communicating the storage compartment 111 of the inner container 11 and the freezing compartment 112 of the inner container is defined inside the air duct assembly 70, and an air supply fan is disposed inside the air supply duct to promote a cooling air flow generated in the cooling compartment 112 to flow to the storage compartment 111.

In some embodiments, the number of the inner containers 11 is two, and the two inner containers 11 are arranged side by side along the transverse direction. A cover plate 30 is provided in each inner container 11, and an evaporator 20 is provided in a cooling chamber 112 formed in the lower portion of each inner container 11. That is, the refrigerator 1 has two bottom-mounted cooling compartments 112 and two bottom-mounted evaporators. The two cooling chambers 112 are independent of each other and arranged side by side in the lateral direction.

Further, at least two cover plates 30 have the same structure.

Further, the two inner containers 11 may have the same or similar structure.

Further, when the refrigerator 1 further includes the return hoods 40, the number of the return hoods 40 is two, and the two return hoods 40 also have the same structure. When the refrigerator 1 further includes the air duct assemblies 70, the structures of the two air duct assemblies 70 and the matching relationship between the two air duct assemblies 70 and the inner container 11 are also substantially the same, and the description thereof is omitted.

In some embodiments, the two liners 11 can be a freezing liner and a temperature-changing liner, respectively, and the two storage compartments defined in the two liners 11 can be a freezing compartment and a temperature-changing compartment, respectively. The temperature of the freezing chamber is usually between-24 ℃ and-14 ℃, and the temperature of the variable temperature chamber can be randomly adjusted to between-24 ℃ and 8 ℃.

In some embodiments, the refrigerator body 10 of the refrigerator 1 further includes another inner container located above the two inner containers 11, the other inner container defines another storage compartment 121 and another cooling chamber 122 located at the rear side of the other storage compartment 121, and another evaporator 21 is disposed in the other cooling chamber 122 to provide cold energy to the other storage compartment 121 through the other evaporator 21.
