Description

Technical Field

[0001] The invention relates to the technical field of household appliances, and in particular to a refrigerator with a drain port provided with a filter plate. Background Art

[0002] For common air-cooled refrigerators, the defrost heating wire will automatically defrost according to a certain program, which solves the disadvantage of manual defrosting in direct-cooling refrigerators. However, due to factors such as insufficient power of the heating wire and short defrosting time, incomplete defrosting may occur. Large ice cubes fall off the evaporator and gather at the drain outlet. As the usage time increases, the drain outlet will eventually be blocked by ice, the evaporator will be blocked by ice, and the refrigeration effect will deteriorate. Summary of the invention

[0003] In view of the above problems, an object of the present invention is to provide a refrigerator that overcomes the above problems or at least partially solves the above problems.

[0004] A further object of the present invention is to increase the storage capacity of the freezer compartment and to improve the heat dissipation efficiency of the compressor compartment.

[0005] The present invention provides a refrigerator, comprising:

[0006] A box body, which defines a cooling chamber, wherein an evaporator is arranged in the cooling chamber for cooling the airflow entering the cooling chamber, and a drain port is formed on the bottom wall of the cooling chamber for discharging defrost water of the evaporator;

[0007] The filter plate is arranged between the lower surface of the evaporator and the drain outlet, and is spaced apart from the lower surface of the evaporator and the drain outlet. The filter plate is formed with a plurality of through holes penetrating the upper surface and the lower surface thereof.

[0008] Optionally, the size of the through hole adjacent to the drain outlet is smaller than the size of the through hole away from the drain outlet.

[0009] Optionally, the upper surface of the bottom wall of the cooling chamber includes a water receiving section located directly below the evaporator;

[0010] The projection of the water receiving section on the vertical plane parallel to the lateral side wall of the cooling chamber includes:

[0011] The rear inclined straight section extends from the back to the front in a downward inclination;

[0012] A front inclined straight section extends obliquely forward and upward from the front end of the rear inclined straight section;

[0013] A drainage outlet is formed at the junction of the rear inclined straight section and the front inclined straight section.

[0014] Optionally, the filter plate is located in a space defined between the lower surface of the evaporator and the water receiving section;

[0015] The filter plate includes:

[0016] The rear inclined plate section is located above the rear inclined straight section and extends from the rear to the front in a downwardly inclined manner;

[0017] A front inclined plate section extends obliquely forward and upward from the front end of the rear inclined plate section;

[0018] A plurality of through holes are formed on both the rear inclined plate section and the front inclined plate section, and the through holes at the junction of the rear inclined plate section and the front inclined plate section are communicated.

[0019] Optionally, the box includes:

[0020] A freezing inner container located at the bottom defines a freezing chamber and a cooling chamber located directly below the freezing chamber;

[0021] The bottom wall of the freezing inner container is configured as the bottom wall of the cooling chamber.

[0022] Optionally, the box further comprises:

[0023] The freezer compartment air supply duct is arranged on the inner side of the rear wall of the freezer liner and has a plurality of air supply ports for supplying air to the freezer compartment;

[0024] The blower is arranged behind the evaporator and configured to cause at least part of the air flow after cooling of the evaporator to flow into the freezing chamber through the freezing chamber air supply duct.

[0025] Optionally, a compressor cabin is also defined in the box body, and the compressor cabin is located at the rear and lower part of the cooling chamber.

[0026] Optionally, the compressor cabin is provided with a compressor, a cooling fan and a condenser which are distributed in a transverse interval;

[0027] The bottom wall of the box body defines a bottom air inlet adjacent to the condenser and a bottom air outlet adjacent to the compressor which are arranged transversely;

[0028] The heat dissipation fan is also configured to draw in ambient air from the bottom air inlet and force the air to first pass through the condenser, then pass through the compressor, and then flow into the surrounding environment from the bottom air outlet.

[0029] Optionally, the box further comprises:

[0030] A bottom plate, comprising a bottom horizontal section located at the front side of the bottom and a bent section extending backward and upward from a rear end of the bottom horizontal section, wherein the bent section comprises an inclined section located above the bottom air inlet and the bottom air outlet;

[0031] The support plate is located behind the bottom horizontal section, and the bent section extends to the top of the support plate. The support plate and the bottom horizontal section form the bottom wall of the box body, and are spaced apart from the bottom horizontal section so that the rear end of the bottom horizontal section and the front end of the support plate define a bottom opening;

[0032] Two side panels, extending upward from the lateral sides of the support plate to the lateral sides of the bending section respectively, forming two lateral side walls of the press cabin;

[0033] A vertically extending back plate extends upward from the rear end of the support plate to the rear end of the bent section to form a rear wall of the press cabin;

[0034] The compressor, the cooling fan and the condenser are arranged on the support plate in sequence and spaced apart in the transverse direction, and are located in the space defined by the support plate, the two side plates, the back plate and the bending section;

[0035] The refrigerator also includes a partition, which is arranged behind the bending section, with its front part connected to the rear end of the bottom horizontal section and its rear part connected to the front end of the support plate, and is arranged to divide the bottom opening into a bottom air inlet and a bottom air outlet arranged laterally.

[0036] Optionally, the box further comprises:

[0037] The wind shield extending forward and backward is located between the bottom air inlet and the bottom air outlet, extends from the lower surface of the bottom horizontal section to the lower surface of the support plate, and is connected to the lower end of the partition, so that the bottom air inlet and the bottom air outlet can be completely isolated by the wind shield and the partition, so that when the refrigerator is placed on a supporting surface, the space between the bottom wall of the box body and the supporting surface is transversely divided to allow external air to enter the compressor cabin through the bottom air inlet located on one lateral side of the wind shield under the action of the heat dissipation fan, and flow through the condenser and the compressor in sequence, and finally flow out from the bottom air outlet located on the other lateral side of the wind shield.

[0038] In the refrigerator of the present invention, a filter plate is arranged between the lower surface of the evaporator and the drain outlet. When the evaporator is not completely defrosted, ice cubes condensed on the evaporator fall onto the filter plate. The filter plate only allows very small-sized ice cubes to pass through, thereby reducing the volume of ice cubes near the drain outlet and reducing the probability of ice blockage.

[0039] Furthermore, in the refrigerator of the present invention, the water receiving section has a special structure so that the drain port is located below the evaporator. The hot air entering the cooling chamber through the drain port will first pass through the evaporator and be cooled by the evaporator before entering the freezer, or will frost on the evaporator (in the subsequent defrosting stage, the frost layer on the evaporator will be melted again), thereby avoiding affecting the blower and the freezer.

[0040] Furthermore, in the refrigerator of the present invention, the bottom wall of the refrigerator is defined with horizontally arranged bottom air inlet and bottom air outlet, and the heat dissipation airflow circulates at the bottom of the refrigerator, making full use of the space between the refrigerator and the supporting surface. There is no need to increase the distance between the rear wall of the refrigerator and the cabinet, thereby reducing the space occupied by the refrigerator and ensuring good heat dissipation of the compressor cabin.

[0041] Furthermore, in the refrigerator of the present invention, the bottom air inlet and the bottom air outlet are completely isolated by wind shields and partitions, ensuring that the external air entering the condenser and the hot air exhausted from the compressor will not flow together, thereby improving the heat dissipation effect and ensuring the normal operation of the refrigerator refrigeration system.

It should be understood by those skilled in the art that these drawings are not necessarily drawn to scale. In the accompanying drawings:

[0047] Figure 4 It is a partial exploded schematic diagram of a refrigerator according to an embodiment of the present invention. DETAILED DESCRIPTION

[0048] This embodiment provides a refrigerator 100. Figures 1 to 4 In the following description, the directions or positional relationships indicated by "front", "rear", "up", "down", "left", "right", etc. are directions or positional relationships based on the refrigerator 100 itself as a reference. Figure 1 , Figure 3 , Figure 4 The indicated direction, “horizontal”, refers to the left-right direction, which is a direction parallel to the width direction of the refrigerator 100 .

[0049] like Figure 1 , Figure 2 As shown, the refrigerator 100 includes a box body, which generally includes an outer shell 110 and a storage liner disposed inside the outer shell 110, and the space between the outer shell 110 and the storage liner is filled with a heat-insulating material (forming a foaming layer). A storage compartment is defined in the storage liner.

[0050] As can be appreciated by those skilled in the art, the cabinet further defines a cooling chamber 135 and a compressor cabin, and the refrigerator 100 may further include an evaporator 101, a blower 103, a compressor 104, a condenser 105, and a throttling element (not shown), etc. The evaporator 101 is disposed in the cooling chamber 135, the compressor 104 and the condenser 105 are disposed in the compressor cabin, and the evaporator 101 is connected to the compressor 104, the condenser 105, and the throttling element via a refrigerant pipeline to form a refrigeration cycle, and the compressor 104 is cooled when it is started to cool the air flowing through it.

[0051] In order to discharge the defrosted water of the evaporator 101, generally, a drain port 130a is formed on the bottom wall of the cooling chamber 135. In particular, in the present embodiment, the refrigerator 100 further includes a filter plate 136, which is located between the lower surface of the evaporator 101 and the drain port 130a, and is spaced from both the lower surface of the evaporator 101 and the drain port 130a, and the filter plate 136 is formed with a plurality of through holes 136a penetrating the upper surface and the lower surface thereof.

[0052] If the evaporator 101 is not completely defrosted, the ice cubes condensed on the evaporator 101 will fall on the filter plate 136. The filter plate 136 has a through hole 136a, which only allows very small ice cubes to pass through, reducing the volume of ice cubes near the drain port 130a and reducing the probability of ice blockage. In addition, during the defrosting process of the evaporator 101, the heat of the heating wire that heats the evaporator 101 will be transferred to the filter plate 136. The ice cubes that fall on the filter plate 136 will be melted for the second time, which can reduce the volume of the ice cubes, greatly reducing the workload of the heating wire that melts the ice cubes at the drain port 130a.

[0053] Among them, the filter plate can be an aluminum plate, which has good thermal conductivity and is more conducive to the melting of ice cubes.

[0054] The size of the through hole 136a near the drain outlet 130a is smaller than the size of the through hole 136a far from the drain outlet 130a, thereby minimizing the volume of ice near the drain outlet 130a and further reducing the probability of ice blockage at the drain outlet 130a.

[0055] The upper surface of the bottom wall of the cooling chamber 135 includes a water receiving section located directly below the evaporator 101. The projection of the water receiving section on a vertical plane parallel to the lateral side wall of the cooling chamber 135 includes a rear inclined straight section 1302 extending downwardly from the rear to the front and a front inclined straight section 1301 extending obliquely from the front end of the rear inclined straight section 1302 to the front and upward. The aforementioned drain port 130a is formed at the intersection of the rear inclined straight section 1302 and the front inclined straight section 1301. Thus, the drain port 130a is located below the evaporator 101.

[0056] In the existing refrigerator 100, the water receiving section below the evaporator 101 generally has only one inclined surface, and the lowest point of the inclined surface (the location of the drain outlet) is generally located downstream of the evaporator 101. The hot air entering the cooling chamber 135 through the drain outlet 130a does not pass through the evaporator 101, and is prone to frost or ice on the blower 103 located downstream of the evaporator 101, or directly enters the freezer chamber 131, affecting the temperature of the freezer chamber 131.

[0057] In this embodiment, by designing a water receiving section with the aforementioned special structure, the drain port 130a is located below the evaporator 101. The hot air entering the cooling chamber 135 through the drain port 130a will first pass through the evaporator 101, and then enter the freezer chamber 131 after being cooled by the evaporator 101, or frost will form on the evaporator 101 (in the subsequent defrosting stage, the frost layer on the evaporator 101 will be melted again), thereby avoiding affecting the blower 103 and the freezer chamber 131.

[0058] like Figure 1 and Figure 2 As shown, the filter plate 136 is within the space defined between the lower surface of the evaporator 101 and the water receiving section. The filter plate 136 may include a rear inclined plate section 1362 located above the rear inclined straight section 1302 and extending downwardly from the rear to the front, and a front inclined plate section 1361 extending forwardly and upwardly from the front end of the rear inclined plate section 1362, thereby forming the lowest point of the filter plate 136 at the intersection of the rear inclined plate section 1362 and the front inclined plate section 1361.

[0059] like Figure 2 As shown, the rear inclined plate segment 1362 and the front inclined plate segment 1361 should both be formed with a plurality of through holes 136a, and the through holes 136a at the intersection of the rear inclined plate segment 1362 and the front inclined plate segment 1361 are connected, that is, a row of through holes 136a at the intersection of the rear inclined plate segment 1362 is connected to a row of through holes 136a at the intersection of the front inclined plate segment 1361, to prevent defrost water from gathering at the direct intersection of the rear inclined plate segment 1362 and the front inclined plate segment 1361.

[0060] The lowest point of the projection of the filter plate 136 on the vertical plane parallel to the lateral side wall of the cooling chamber 135 is located directly above the lowest point of the projection of the water receiving section on the vertical plane parallel to the lateral side wall of the cooling chamber 135 .

[0061] The distance between the lowest point of the projection of the filter plate 136 on the vertical plane parallel to the lateral side wall of the cooling chamber 135 and the lowest point of the projection of the evaporator 101 on the vertical plane is the same as the distance between the filter plate 136 and the lowest point of the projection of the water receiving section on the vertical plane parallel to the lateral side wall of the cooling chamber 135. It can also be understood that the filter plate 136 is located 1 / 2 between the evaporator 101 and the water receiving section.

[0062] More specifically, the storage liner includes a freezing liner 130 located at the bottom, the freezing liner 130 defines a freezing chamber 131 and the aforementioned cooling chamber 135 located directly below the freezing chamber 131 , and the bottom wall of the freezing liner 130 constitutes the bottom wall of the cooling chamber 135 .

[0063] Compared with the conventional refrigerator 100 in which the cooling chamber 135 is located behind the freezing chamber 131, in the refrigerator 100 of the present embodiment, the cooling chamber 135 no longer occupies the space behind the freezing chamber 131, thereby increasing the depth of the freezing chamber 131 and the storage capacity of the freezing chamber 131. Furthermore, the presence of the cooling chamber 135 raises the height of the freezing chamber 131 above it, reducing the degree of bending of the user when taking and placing items in the freezing chamber 131, thereby improving the user's experience, and being particularly convenient for the elderly.

[0064] The cooling chamber 135 may be defined by a cover shell (not numbered) buckled on the bottom wall of the freezing liner 130 and the bottom wall of the freezing liner 130 .

[0065] The evaporator 101 as a whole can be placed horizontally in the cooling chamber 135 in a flat cubic shape, that is, the length and width of the evaporator 101 are parallel to the horizontal plane, the thickness surface is placed perpendicular to the horizontal plane, and the thickness dimension is significantly smaller than the length dimension of the evaporator 101. By placing the evaporator 101 horizontally in the cooling chamber 135, the evaporator 101 is prevented from occupying more space, and the storage volume of the freezing chamber 131 above the cooling chamber 135 is guaranteed.

[0066] The cabinet also includes a freezer compartment air supply duct 134 and a blower 103. The freezer compartment air supply duct 134 is located on the inner side of the rear wall of the freezer liner 130 and has at least one freezer compartment air supply port connected to the freezer compartment 131. The blower 103 is disposed behind the evaporator 101 and is configured to cause at least part of the air flow cooled by the evaporator 101 to flow into the freezer compartment 131 through the freezer compartment air supply duct 134.

[0067] An air outlet connected to the air inlet of the freezer compartment air supply duct 134 is formed at the rear end of the cover shell, so that the air flow cooled by the evaporator 101 in the cooling chamber can enter the freezer compartment air supply duct 134. A front return air inlet 135a is formed on the front wall of the cover shell, and the return air flow of the freezer compartment 131 enters the cooling chamber through the front return air inlet 135a to be cooled by the evaporator 101.

[0068] like Figure 1As shown, the box body includes a refrigerating liner 120 and a variable temperature liner. The variable temperature liner is located directly above the freezing liner 130, and defines a variable temperature chamber 141 therein. The refrigerating liner 120 is located directly above the variable temperature liner, and defines a refrigerating chamber 121 therein. A freezing chamber door 132 is provided on the front side of the freezing liner 130, a refrigerating chamber door 122 is provided on the front side of the refrigerating liner 120, and a variable temperature chamber door 142 is provided on the front side of the variable temperature liner.

[0069] The refrigerating chamber 121 can be divided into a plurality of storage spaces by a plurality of transverse partitions 123 spaced apart vertically, so as to facilitate the classified storage of articles. The variable temperature chamber 141 is provided with a storage container 143 , and the freezing chamber 131 is provided with a storage drawer 133 .

[0070] The box body also includes a variable temperature room air supply duct 144 and a variable temperature room return air duct (not shown). Figure 1 As shown, the variable temperature chamber supply air duct 144 can be controllably connected to the freezer chamber supply air duct 134 through a variable temperature chamber air door 145, and the variable temperature chamber return air duct has an inlet connected to the variable temperature inner tank and an outlet connected to the cooling chamber 135 to transport the return air flow of the variable temperature chamber 141 to the cooling chamber 135.

[0071] like Figure 1 As shown, the refrigerating chamber 121 may have an independent refrigerating evaporator 125 and a refrigerating blower 126, and the refrigerating evaporator 125 and the refrigerating blower 126 are arranged in a refrigerating chamber air supply duct 124 located on the inner side of the rear wall of the refrigerating liner 120, and the refrigerating chamber air supply duct 124 has a refrigerating chamber air supply port for supplying air to the refrigerating chamber 121.

[0072] Further in particular, see again Figure 1 The press cabin is located at the rear and lower part of the cooling chamber 135, so that the freezer chamber 131 above the cooling chamber 135 no longer needs to make way for the press cabin. The freezer chamber 131 can be a regular rectangular space, which is convenient for placing large items that are difficult to divide, solving the pain point that large items cannot be placed in the bottom freezer chamber 131.

[0073] In particular, if Figure 3 and Figure 4 As shown, the compressor cabin is provided with a compressor 104, a cooling fan 106 and a condenser 105 which are spaced apart in sequence along the lateral direction.

[0074] In some embodiments, Figure 4 As shown, the rear wall of the compressor cabin and the plate section 1162 corresponding to the compressor 104 are formed with at least one rear air outlet 1162a.

[0075] In fact, before the present invention, the general design idea of ​​those skilled in the art is to open a rear air inlet facing the condenser 105 and a rear air outlet 1162a facing the compressor 104 on the rear wall of the compressor cabin, so as to complete the circulation of the heat dissipation airflow at the rear of the compressor cabin; or to form ventilation holes on the front wall and the rear wall of the compressor cabin respectively, so as to form a heat dissipation circulation air path in the front-to-back direction. When faced with the problem of improving the heat dissipation effect of the compressor cabin, those skilled in the art usually increase the number of rear air inlet holes and rear air outlet holes 1162a on the rear wall of the compressor cabin to expand the ventilation area, or increase the heat exchange area of ​​the condenser 105, such as using a U-shaped condenser with a larger heat exchange area.

[0076] The applicant of the present invention creatively realized that the larger the heat exchange area of ​​the condenser 105 and the ventilation area of ​​the compressor compartment, the better. In the conventional design scheme of increasing the heat exchange area of ​​the condenser 105 and the ventilation area of ​​the compressor compartment, the problem of uneven heat dissipation of the condenser 105 will be brought about, which will have an adverse effect on the refrigeration system of the refrigerator 100. Therefore, the applicant of the present invention breaks away from the conventional design ideas and creatively proposes a new scheme different from the conventional design, such as Figure 3 and Figure 4 As shown, the bottom wall of the refrigerator 100 is defined with a bottom air inlet 110a adjacent to the condenser and a bottom air outlet 110b adjacent to the compressor 104 which are arranged laterally. The refrigerator 100 completes the circulation of the heat dissipation airflow at its bottom, making full use of the space between the refrigerator 100 and the supporting surface. There is no need to increase the distance between the back wall of the refrigerator 100 and the cabinet, which reduces the space occupied by the refrigerator 100 while ensuring good heat dissipation of the compressor cabin. This fundamentally solves the pain point of the inability to balance the heat dissipation of the compressor cabin and the space occupation of the built-in refrigerator 100, which is of particular importance.

[0077] The cooling fan 106 is configured to draw ambient air from the surrounding environment of the bottom air inlet 110a and force the air to pass through the condenser 105 first, then pass through the compressor 104, and then flow to the surrounding environment from the bottom air outlet 110b, thereby dissipating heat from the condenser 105 and the compressor 104.

[0078] In the vapor compression refrigeration cycle, the surface temperature of the condenser 105 is generally lower than the surface temperature of the compressor 104 . Therefore, in the above process, the external air first cools the condenser 105 and then cools the compressor 104 .

[0079] Further in particular, in a preferred embodiment of the present invention, the plate section 1161 of the back panel 116 (the rear wall of the compressor chamber) facing the condenser 105 is a continuous plate surface, that is, there are no heat dissipation holes on the plate section 1161 of the back panel 116 facing the condenser 105.

[0080] The applicant of the present invention creatively realized that even without increasing the heat exchange area of ​​the condenser 105, reducing the ventilation area of ​​the compressor cabin in an abnormal manner can form a better heat dissipation airflow path and still achieve a better heat dissipation effect.

[0081] In the preferred embodiment of the present invention, the applicant breaks through the conventional design ideas and designs the rear wall (back panel 116) of the compressor cabin and the plate section 1161 corresponding to the condenser 105 as a continuous plate surface, so that the heat dissipation airflow entering the compressor cabin is sealed at the condenser 105, so that the ambient air entering from the bottom air inlet 110a is more concentrated at the condenser 105, thereby ensuring the uniformity of heat exchange of each condensation section of the condenser 105, and facilitating the formation of a better heat dissipation airflow path, which can also achieve better heat dissipation effect.

[0082] Furthermore, since the plate section 1161 of the back plate 116 facing the condenser 105 is a continuous plate surface without air inlet holes, it avoids the situation in the conventional design where both the air outlet and the air inlet are concentrated at the rear of the compressor cabin, resulting in the hot air blown out from the compressor cabin not being cooled by the ambient air in time and re-entering the compressor cabin, which has an adverse effect on the heat exchange of the condenser 105, thereby ensuring the heat exchange efficiency of the condenser 105.

[0083] In some embodiments, Figure 4 As shown, the two lateral side walls of the compressor cabin are each formed with a side vent 119a, which can be covered with a vent cover 108, and the vent cover 108 is formed with grille-type vent holes; the outer shell of the refrigerator 100 includes two lateral box side panels 111, which extend vertically to form two side walls of the refrigerator 100, and the two box side panels 111 are respectively formed with a side opening 111a connected to the corresponding side vent 119a, so that the heat dissipation airflow flows to the outside of the refrigerator 100. This further increases the heat dissipation path and ensures the heat dissipation effect of the compressor cabin.

[0084] More specifically, the condenser 105 includes a first straight section 1051 extending transversely, a second straight section 1052 extending forward and backward, and a transition curved section (not numbered) connecting the first straight section 1051 and the second straight section 1052, thereby forming an L-shaped condenser 105 with a suitable heat exchange area. The plate section 1161 corresponding to the rear wall (back plate 116) of the compressor cabin and the condenser 105 is also the plate section 1161 of the back plate 116 facing the first straight section 1051.

[0085] The ambient air flow entering through the side vent 119a directly exchanges heat with the second straight section 1052, and the ambient air entering through the bottom air inlet 110a directly exchanges heat with the first straight section 1051, thereby further concentrating more ambient air entering the compressor cabin at the condenser 105, ensuring the uniformity of the overall heat dissipation of the condenser 105.

[0086] In particular, if Figure 3 and Figure 4 As shown, the refrigerator 100 includes a bottom plate, a support plate 112, two side plates 119 and a vertically extending back plate 116. The support plate 112 constitutes the bottom wall of the compressor cabin, which is used to support the compressor 104, the heat dissipation fan 106 and the condenser 105. The two side plates 119 respectively constitute the two lateral side walls of the compressor cabin, and the vertically extending back plate 116 constitutes the rear wall of the compressor cabin.

[0087] Further in particular, the bottom plate includes a bottom horizontal section 113 located on the front side of the bottom and a bending section extending backward and upward from the rear end of the bottom horizontal section 113, the bending section extends to the top of the support plate 112, the compressor 104, the heat dissipation fan 106 and the condenser 105 are arranged on the support plate 112 in sequence along the horizontal direction, and are located in the space defined by the support plate 112, the two side panels, the back panel 116 and the bending section.

[0088] The support plate 112 and the bottom horizontal section 113 together constitute the bottom wall of the refrigerator 100, and the support plate 112 and the bottom horizontal section 113 are spaced apart so as to define a bottom opening by using the rear end of the bottom horizontal section 113 and the front end of the support plate 112, wherein the bending section has an inclined section 114 located above the bottom air inlet 110a and the bottom air outlet 110b. The two side panels extend upward from the two lateral sides of the support plate 112 to the two lateral sides of the bending section respectively to close the two lateral sides of the compressor cabin; the back panel 116 extends upward from the rear end of the support plate 112 to the rear end of the bending section.

[0089] Specifically, the bending section may include a vertical section 1131, the aforementioned inclined section 114 and a top horizontal section 115, the vertical section 1131 extends upward from the rear end of the bottom horizontal section 113, the inclined section 114 extends rearward and upward from the upper end of the vertical section 1131 to the top of the support plate 112, and the top horizontal section 115 extends rearward from the rear end of the inclined section 114 to the back plate to shield the compressor 104, the cooling fan 106 and the top of the condenser 105.

[0090] The front surface of the inclined section 114 may be formed with a protrusion 114a protruding upward, and the protrusion 114a is formed with a through hole 114a1. The refrigerator 100 further includes a drain pipe (not shown), one end of which is connected to the drain port 130a, and the other end of which passes through the through hole 114a1 and extends to an evaporation dish (not numbered) provided in the compressor cabin to discharge the defrost water into the evaporation dish. The evaporation dish is generally located below the condenser 105, and the heat emitted by the condenser 105 and the compressor 104 evaporates the defrost water in the evaporation dish.

[0091] The refrigerator 100 also includes a partition 117, which is arranged behind the bending section, with its front portion connected to the rear end of the bottom horizontal section 113, and its rear portion connected to the front end of the support plate 112, and is configured to divide the bottom opening into a horizontally arranged bottom air inlet 110a and a bottom air outlet 110b.

[0092] As can be seen from the foregoing, the bottom air inlet 110a and the bottom air outlet 110b of the present embodiment are defined by a partition 117, a support plate 112, and a bottom horizontal section 113, thereby forming a groove-shaped bottom air inlet 110a and a bottom air outlet 110b with a larger opening size, thereby increasing the air inlet and outlet area, reducing the air inlet resistance, making the air flow smoother, and making the manufacturing process simpler, thereby making the overall stability of the compressor cabin stronger.

[0093] In particular, the applicant of the present invention creatively realized that the slope structure of the inclined section 114 can guide and rectify the incoming air flow, so that the air flow entering from the bottom air inlet 110a can flow to the condenser 105 more concentratedly, avoiding the air flow being too dispersed and unable to pass more through the condenser 105, thereby further ensuring the heat dissipation effect of the condenser 105; at the same time, the slope of the inclined section 114 guides the outlet air of the bottom air outlet 110b to the front side of the ground air outlet, so that the outlet air flow can flow out of the compressor cabin more smoothly, thereby further improving the smoothness of the air flow.

[0094] More particularly, in a preferred embodiment, the angle between the inclined section 114 and the horizontal plane is less than 45°. In this embodiment, the inclined section 114 has a better effect of guiding and rectifying the airflow.

[0095] Furthermore, surprisingly, the inventors of the present application creatively realized that the slope of the inclined section 114 has a better suppressing effect on airflow noise. In prototype tests, the noise of the compressor cabin having the aforementioned specially designed inclined section 114 can be reduced by more than 0.65 decibels.

[0096] In addition, in the conventional refrigerator 100, the bottom of the refrigerator 100 generally has a bearing plate of a substantially flat structure, and the compressor 104 is arranged on the inner side of the bearing plate. The vibration generated by the operation of the compressor 104 has a greater impact on the bottom of the box 100. In this embodiment, as mentioned above, the bottom of the refrigerator 100 is constructed into a three-dimensional structure by a bottom plate and a support plate 112 of a special structure, providing an independent three-dimensional space for the arrangement of the compressor 104, and the support plate 112 is used to carry the compressor 104, thereby reducing the impact of the vibration of the compressor 104 on other components at the bottom of the box 100. In addition, by designing the refrigerator 100 as the above-mentioned ingenious special structure, the structure of the bottom of the refrigerator 100 is compact and the layout is reasonable, which reduces the overall volume of the refrigerator 100, and at the same time fully utilizes the space at the bottom of the refrigerator 100, ensuring the heat dissipation efficiency of the compressor 104 and the condenser 105.

[0097] More specifically, a wind shield 1056 is provided at the upper end of the condenser 105. The wind shield 1056 may be a wind shield sponge, filling the space between the upper end of the condenser 105 and the bending section. That is to say, the wind shield 1056 covers the upper ends of the first straight section 1051, the second straight section 1052 and the transition curved section, and the upper end of the wind shield 1056 should abut against the bending section to seal the upper end of the condenser 105, so as to prevent part of the air entering the compressor cabin from passing through the space between the upper end of the condenser 105 and the bending section instead of passing through the condenser 105, thereby allowing as much air as possible entering the compressor cabin to exchange heat through the condenser 105, thereby further improving the heat dissipation effect of the condenser 105.

[0098] In some embodiments, the refrigerator 100 further includes a windshield strip 107 extending forward and backward, the windshield strip 107 being located between the bottom air inlet 110a and the bottom air outlet 110b, extending from the lower surface of the bottom horizontal section 113 to the lower surface of the support plate 112, and connected to the lower end of the partition 117, so that the bottom air inlet 110a and the bottom air outlet 110b are completely isolated by the windshield strip 107 and the partition 117, so that when the refrigerator 100 is placed on a supporting surface, the space between the bottom wall of the refrigerator 100 and the supporting surface is horizontally separated. The bottom air inlet 110a and the bottom air outlet 110b are connected to each other through the bottom air inlet 110a on the other side of the wind shield 107, thereby completely isolating the bottom air inlet 110a and the bottom air outlet 110b, thereby ensuring that the outside air entering the condenser 105 and the heat dissipation air discharged from the compressor 104 will not flow into each other, thereby further ensuring the heat dissipation efficiency.

[0099] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
