[0020] Optionally, a compressor, a heat dissipation fan and a condenser are arranged at intervals in the horizontal direction in the compressor compartment;

[0021] The bottom wall of the refrigerator defines a bottom air inlet adjacent to the condenser and a bottom air outlet adjacent to the compressor arranged horizontally;

[0022] The heat dissipation fan is further configured to suck ambient air from the bottom air inlet and cause the air to pass through the condenser first, then through the compressor, and then flow to the surrounding environment from the bottom air outlet.

[0023] Optionally, the refrigerator further includes:

[0024] A bottom plate, which includes a bottom horizontal section located at the front side of the bottom and a bent section bent and extending backward and upward from the rear end of the bottom horizontal section.

[0044] Figure 8 is a partial exploded schematic view according to an embodiment of the present invention. Detailed Embodiments

[0045] This embodiment provides a refrigerator 100. The refrigerator 100 according to the embodiments of the present invention will be described hereinafter with reference to Figures 1 to 8 In the following description, the orientation or positional relationship indicated by "front", "rear", "upper", "lower", "left", "right", etc. is based on the refrigerator 100 itself as a reference. "Front" and "rear" are the directions indicated by Figure 1 As Figure 2 shown, "lateral" also refers to the left-right direction, which is a direction parallel to the width direction of the refrigerator 100.

[0046] As Figure 1 shown, the refrigerator 100 includes a cabinet, which generally includes an outer shell 110 and a storage inner liner provided inside the outer shell 110. A heat-insulating material (forming a foamed layer) is filled in the space between the outer shell 110 and the storage inner liner. Storage compartments are defined in the storage inner liner.

[0047] As can be appreciated by those skilled in the art, the cabinet also defines a cooling chamber and a compressor compartment 102, 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, the compressor 104 and the condenser 105 are disposed in the compressor compartment 102, 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 loop, which cools down when the compressor 104 starts to cool the air flowing through it.

[0048] Specifically, in this embodiment, a storage compartment 131 and a cooling chamber located below the storage compartment 131 are defined within the lowermost storage inner liner 130.

[0049] Compared with the conventional refrigerator 100 in which the cooling chamber is located behind the storage compartment 131, in the refrigerator 100 of this embodiment, the cooling chamber no longer occupies the space behind the storage compartment 131, increasing the depth dimension of the storage compartment 131 and the storage volume of the storage compartment 131. Moreover, the presence of the cooling chamber raises the height of the storage compartment 131 above it, reducing the degree of bending when the user operates to pick up and place items in the storage compartment 131, improving the user experience, and being particularly convenient for the elderly to use.

[0050] Further specifically, in this embodiment, the air supply duct 134 is disposed in the middle of the inner side of the rear wall of the storage inner liner 130 and is communicated with the cooling chamber for delivering at least part of the air flow cooled by the evaporator 101 into the storage compartment 131.

[0051] In the existing refrigerator 100, the width (lateral dimension) of the air duct is generally approximately the same as the width of the rear wall of the storage inner liner 130. The air duct occupies too much space behind the storage compartment 131, reducing the depth of the storage compartment 131 and affecting the storage volume of the storage drawer 133 disposed in the storage compartment 131. In this embodiment, however, the air supply duct 134 is entirely in the middle of the inner side of the rear wall of the storage inner liner 130, and the width dimension (lateral dimension) of the air supply duct 134 is reduced, reducing the space occupied by the air supply duct 134 and ensuring the volume of the storage compartment 131.

[0052] The air supply duct 134 is formed with at least one air supply port communicating with the storage compartment 131, and a flow guide cover 1341 is formed at each air supply port of the air supply duct 134. The flow guide cover 1341 has at least one flow guide air duct communicating with the air supply port to guide the air flow out of the air supply port.

[0053] The air supply duct 134 may be formed with a plurality of the aforementioned air supply ports, and the plurality of air supply ports are spaced apart vertically. Correspondingly, there are a plurality of flow guide covers 1341.

[0054] In one embodiment, asFigure 2 and Figure 3 As shown in Figure 3 , a vertical beam 136 extending vertically is formed at the front side of the middle part in the transverse direction of the storage inner liner 130. The storage compartment 131 includes two storage spaces located on both transverse sides of the vertical beam 136. A plurality of storage drawers 133 distributed vertically can be arranged in each storage space. Two first door bodies 132 distributed horizontally are arranged at the front side of the storage inner liner 130. The two first door bodies 132 correspond to the two storage spaces one by one to respectively open and close the corresponding storage spaces, forming a pair of opening doors.

[0055] In this embodiment, the air supply duct 134 is located directly behind the vertical beam 136, that is, the width dimension of the air supply duct 134 is substantially the same as the width dimension of the vertical beam 136. The section of the air supply duct 134 corresponding to the rear wall of the storage inner liner 130 can be vertically arranged at a position approximately in the middle of the inner side of the rear wall of the storage inner liner 130. Thus, in the case where it is difficult to increase the transverse dimension of the storage space, by changing the position of the air supply duct 134, the depth dimension of the storage space is increased, and the storage volume of the side-by-side refrigerator 100 is improved.

[0056] In some alternative embodiments, a vertical partition (not shown) extending vertically can be arranged at the middle part in the transverse direction of the storage inner liner 130. The storage compartment 131 is separated into two storage spaces on the left and right by the vertical partition. Correspondingly, the front side of the storage inner liner 130 also has a pair of opening doors to open and close the corresponding storage spaces.

[0057] In this embodiment, the air supply duct 134 is located directly behind the vertical partition, that is, the width dimension of the air supply duct 134 is substantially the same as the width dimension of the vertical partition. The section of the air supply duct 134 corresponding to the rear wall of the storage inner liner 130 can be vertically arranged at a position approximately in the middle of the inner side of the rear wall of the storage inner liner 130.

[0058] For the above two embodiments, since the storage compartment 131 is divided into two storage spaces, for the sake of facilitating the air supply uniformity of the two storage spaces, in a preferred embodiment, as Figure 3 shown, the flow guide cover 1341 has two flow guide air ducts. One of the flow guide air ducts extends obliquely forward to the left in the transverse direction, and a left opening 134b communicating with the air supply port is formed at the left end surface of the flow guide air duct to guide the air flow to the left front, so that the air flow flows into the storage space on the left side. The other flow guide air duct extends obliquely forward to the right in the transverse direction, and a right opening 134a communicating with the air supply port is formed at the right end surface of the flow guide air duct to guide the air flow to the right front, so that the air flow flows into the storage space on the right side.

[0059] In the embodiment with the aforementioned vertical beam 136, the left opening 134b and the right opening 134a of the aforementioned design blow the air flow in the air supply duct 134 into the storage space on the left side and the storage space on the right side respectively, ensuring the uniformity of air supply in the two storage spaces.

[0060] In the embodiment with the aforementioned vertical partition, the left opening 134b and the right opening 134a of the aforementioned design avoid the vertical partition directly in front of the air supply duct 134, avoiding the influence of the vertical partition on air supply. At the same time, they blow into the storage space on the left side and the storage space on the right side respectively, ensuring the uniformity of air supply in the two storage spaces.

[0061] In some embodiments, as Figure 4 shown, the storage room 131 is an integral whole, and a plurality of vertically distributed storage drawers 133 are arranged in the storage room 131.

[0062] In this embodiment, as Figure 5 shown, the flow guide cover 1341 has a flow guide air duct, which extends in a gradually expanding manner from the rear to the front. The front end face of the flow guide air duct forms a front opening 134c communicating with the air supply opening. The air flow from the air supply is made to flow in two diagonal directions in the transverse direction of the storage room 131 through the gradually expanding flow guide air duct, ensuring the uniformity of air supply in the entire space of the storage room 131. For the storage room 131 equipped with storage drawers 133, correspondingly, the air flow from the air supply is made to flow in two diagonal directions in the transverse direction of the storage drawers 133.

[0063] The number of air supply openings formed by the air supply duct 134 can be the same as the number of storage drawers 133 arranged in the storage room 131 or the same as the vertical number of storage drawers 133 arranged in a storage space. Correspondingly, the number of flow guide covers 1341 is the same as the number of storage drawers 133, and there is a flow guide cover 1341 obliquely above each storage drawer 133, so that the air flow blows from the upper open part of the storage drawer 133 to the storage drawer 133, increasing the smoothness of air flow.

[0064] The storage inner container 130 is a freezing inner container. Correspondingly, the storage room 131 is a freezing chamber.

[0065] As Figure 1 shown, the refrigerator 100 further includes a blower 103, which can be arranged behind the evaporator 101 and is configured to cause at least part of the air flow cooled by the evaporator 101 to flow through the air supply duct 134 into the storage room 131 to accelerate the air flow circulation and speed up the refrigeration speed.

[0066] As Figure 1 shown, the cooling chamber can be defined by a cover shell 135 buckled on the bottom wall of the storage inner container 130 and the bottom wall of the storage inner container 130.

[0067] An air outlet communicating with the air inlet of the air supply air duct 134 is formed at the rear end of the housing 135, so that the air flow cooled by the evaporator 101 in the cooling chamber can enter the air supply air duct 134. A front return air inlet 135a is formed on the front wall of the housing 135. The return air flow of the storage room 131 enters the cooling chamber through the front return air inlet 135a and is cooled by the evaporator 101.

[0068] The evaporator 101 as a whole can be horizontally placed in the cooling chamber in a flat cube shape, that is, the length and width surfaces of the evaporator 101 are parallel to the horizontal plane, and the thickness surface is perpendicular to the horizontal plane, and the thickness dimension is significantly smaller than the length dimension of the evaporator 101. By horizontally placing the evaporator 101 in the cooling chamber, it is avoided that the evaporator 101 occupies more space, and the storage volume of the storage room 131 above the cooling chamber is ensured.

[0069] As Figure 1 shown, the box body includes a refrigerating inner liner 120, which is located directly above the storage inner liner 130, and a refrigerating chamber 121 is defined therein. A refrigerating chamber door body 122 is provided on the front side of the refrigerating inner liner 120. The refrigerating chamber 121 can be divided into a plurality of storage spaces by a plurality of horizontal partitions 123 spaced vertically upward, so as to facilitate the classified storage of items.

[0070] As Figure 1 shown, the refrigerating chamber 121 can have an independent refrigerating evaporator 125 and a refrigerating air supply fan 126. The refrigerating evaporator 125 and the refrigerating air supply fan 126 are arranged in a refrigerating chamber air supply air duct 124 inside the rear wall of the refrigerating inner liner 120. The refrigerating chamber air supply air duct 124 has a refrigerating chamber air supply outlet 124a for supplying air to the refrigerating chamber 121, and a refrigerating chamber return air inlet 124b. The refrigerating chamber return air inlet 124b is formed at the lower end of the refrigerating chamber air supply air duct 124 and is located below the refrigerating evaporator 125.

[0071] Further specifically, in some embodiments, as Figure 6 shown, the compressor compartment 102 is located at the lower rear of the cooling chamber, so that the storage room 131 above the cooling chamber does not need to make way for the compressor compartment 102 anymore. The storage room 131 can be a regular rectangular space, which is convenient for placing large items that are not easy to divide, and solves the pain point that large items cannot be placed in the storage room 131 at the bottom.

[0072] Further specifically, as Figure 8 shown, a compressor 104, a heat dissipation fan 106 and a condenser 105 are arranged in the compressor compartment 102 at intervals in the transverse direction.

[0073] In some embodiments, as Figure 8As shown, at least one rear air outlet hole 1162a is formed in the plate section 1162 corresponding to the compressor 104 on the rear wall of the compressor compartment.

[0074] In fact, before the present invention, the general design idea of those skilled in the art was usually to provide a rear air inlet hole facing the condenser 105 and a rear air outlet hole 1162a facing the compressor 104 on the rear wall of the compressor compartment 102 to complete the circulation of the heat dissipation air flow at the rear of the compressor compartment 102; or to form ventilation holes on the front wall and the rear wall of the compressor compartment 102 respectively to form a heat dissipation circulation air path in the front-rear direction. When facing the problem of improving the heat dissipation effect of the compressor compartment, those skilled in the art usually increased the number of the rear air inlet holes and the rear air outlet holes 1162a on the rear wall of the compressor compartment 102 to expand the ventilation area, or increased the heat exchange area of the condenser 105, for example, by using a U-shaped condenser with a larger heat exchange area.

[0075] However, the applicant of the present invention creatively recognized that the heat exchange area of the condenser 105 and the ventilation area of the compressor compartment are not the larger 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, which has an adverse effect on the refrigeration system of the refrigerator 100. For this reason, the applicant of the present invention breaks away from the conventional design idea and creatively proposes a new scheme different from the conventional design, such as Figure 7 and Figure 8 As shown, the bottom wall of the refrigerator 100 defines a bottom air inlet 110a adjacent to the condenser and a bottom air outlet 110b adjacent to the compressor 104 arranged horizontally. The refrigerator 100 completes the circulation of the heat dissipation air flow at its bottom, making full use of the space between the refrigerator 100 and the supporting surface. Without increasing the distance between the rear wall of the refrigerator 100 and the cabinet, while reducing the space occupied by the refrigerator 100, it ensures good heat dissipation of the compressor compartment, fundamentally solving the pain point that the heat dissipation of the compressor compartment of the built-in refrigerator 100 and the space occupation cannot be balanced, which has particularly important significance.

[0076] The heat dissipation fan 106 is configured to suck ambient air from the surrounding environment of the bottom air inlet 110a and urge the air to first pass through the condenser 105, then pass through the compressor 104, and then flow from the bottom air outlet 110b to the surrounding environment, so as to dissipate heat from the condenser 105 and the compressor 104.

[0077] 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 is first used to cool the condenser 105 and then cool the compressor 104.

[0078] Further particularly, in a preferred embodiment of the present invention, the plate segment 1161 of the back plate 116 (the rear wall of the press compartment) facing the condenser 105 is a continuous plate surface, that is to say, there are no heat dissipation holes on the plate segment 1161 of the back plate 116 facing the condenser 105.

[0079] The applicant of the present invention creatively recognizes that even without increasing the heat exchange area of the condenser 105, abnormally reducing the ventilation area of the press compartment can form a better heat dissipation air flow path, and still achieve a better heat dissipation effect.

[0080] In a preferred solution of the present invention, the applicant breaks through the conventional design concept and designs the plate segment 1161 of the rear wall (back plate 116) of the press compartment corresponding to the condenser 105 as a continuous plate surface, enclosing the heat dissipation air flow entering the press compartment at the condenser 105, so that the ambient air entering from the bottom air inlet 110a is more concentrated at the condenser 105, ensuring the heat exchange uniformity of each condensation section of the condenser 105, and facilitating the formation of a better heat dissipation air flow path, and also achieving a better heat dissipation effect.

[0081] Moreover, since the plate segment 1161 of the back plate 116 facing the condenser 105 is a continuous plate surface and does not have 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 press compartment, resulting in the hot air blown out from the press compartment not being cooled by the ambient air in time and then entering the press compartment again, which has an adverse effect on the heat exchange of the condenser 105. Thus, the heat exchange efficiency of the condenser 105 is ensured.

[0082] In some embodiments, as Figure 8 shown, a side ventilation hole 119a is formed on each of the two lateral side walls of the press compartment. The side ventilation hole 119a can be covered with a ventilation cover plate 108, and the ventilation cover plate 108 is formed with grid-like ventilation small holes; the outer shell of the refrigerator 100 includes two box side plates 111 in the transverse direction. The two box side plates 111 extend vertically to form two side walls of the refrigerator 100, and each of the two box side plates 111 forms a side opening 111a communicating with the corresponding side ventilation hole 119a, so that the heat dissipation air flow flows to the outside of the refrigerator 100. This further increases the heat dissipation path and ensures the heat dissipation effect of the press compartment.

[0083] Further particularly, the condenser 105 includes a first straight section 1051 extending horizontally, a second straight section 1052 extending front and back, and a transition curved section (not labeled) connecting the first straight section 1051 and the second straight section 1052, thereby forming an L-shaped condenser 105 with an appropriate heat exchange area. The plate segment 1161 of the rear wall (back plate 116) of the aforementioned press compartment corresponding to the condenser 105 is the plate segment 1161 of the back plate 116 facing the first straight section 1051.

[0084] The ambient air flowing in through the side ventilation holes 119a directly exchanges heat with the second straight section 1052, and the ambient air flowing in through the bottom air inlet 110a directly exchanges heat with the first straight section 1051. Thus, the ambient air entering the compressor compartment is further concentrated more at the condenser 105, ensuring the uniformity of the overall heat dissipation of the condenser 105.

[0085] Further specifically, as Figure 7 and Figure 8 shown, the refrigerator 100 includes a bottom plate, a support plate 112, two side plates 119, and a vertically extending rear plate 116. The support plate 112 forms the bottom wall of the compressor compartment, and is used to carry the compressor 104, the heat dissipation fan 106, and the condenser 105. The two side plates 119 respectively form the two lateral side walls of the compressor compartment, and the vertically extending rear plate 116 forms the rear wall of the compressor compartment.

[0086] Further specifically, the bottom plate includes a bottom horizontal section 113 located at the front side of the bottom and a bent section that bends and extends backward and upward from the rear end of the bottom horizontal section 113. The bent section extends above the support plate 112. The compressor 104, the heat dissipation fan 106, and the condenser 105 are arranged at intervals in sequence in the transverse direction on the support plate 112, and are located in the space defined by the support plate 112, the two side plates, the rear plate 116, and the bent section.

[0087] The support plate 112 and the bottom horizontal section 113 together form the bottom wall of the refrigerator 100, and the support plate 112 and the bottom horizontal section 113 are spaced apart to define a bottom opening by the rear end of the bottom horizontal section 113 and the front end of the support plate 112. Among them, the bent section has an inclined section 114 located above the bottom air inlet 110a and the bottom air outlet 110b. The two side plates extend upward from the two sides in the transverse direction of the support plate 112 to the two sides in the transverse direction of the bent section to enclose the two lateral sides of the compressor compartment; the rear plate 116 extends upward from the rear end of the support plate 112 to the rear end of the bent section.

[0088] Specifically, the bent 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 backward and upward from the upper end of the vertical section 1131 above the support plate 112, and the top horizontal section 115 extends backward from the rear end of the inclined section 114 to the rear plate to shield the upper part of the compressor 104, the heat dissipation fan 106, and the condenser 105.

[0089] The front surface of the inclined section 114 may be formed with a convex protrusion 114a, and the protrusion 114a is formed with a through hole 114a1. As Figure 4As shown, the refrigerator 100 further includes a drain pipe 140. One end of the drain pipe is connected to the drain opening 130a, and the other end extends through the through hole 114a1 to an evaporating dish (not labeled) disposed in the compressor compartment 102 to drain the defrosting water into the evaporating dish. The evaporating dish is generally located below the condenser 105, and the heat dissipated by the condenser 105 and the compressor 104 evaporates the defrosting water in the evaporating dish.

[0090] The refrigerator 100 further includes a partition member 117. The partition member 117 is disposed behind the bent 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. It is configured to divide the bottom opening into a laterally arranged bottom air inlet 110a and a bottom air outlet 110b.

[0091] As can be seen from the foregoing, the bottom air inlet 110a and the bottom air outlet 110b of this embodiment are defined by the partition member 117, the support plate 112, and the bottom horizontal section 113, thereby forming a trough-shaped bottom air inlet 110a and a bottom air outlet 110b with a relatively large opening size, increasing the air inlet and outlet areas, reducing the air inlet resistance, making the air flow more smooth, and having a simpler manufacturing process, making the overall stability of the compressor compartment stronger.

[0092] In particular, the applicant of the present invention creatively realizes that the slope structure of the inclined section 114 can guide and rectify the incoming air flow, making the air flow entering from the bottom air inlet 110a flow more concentratedly towards the condenser 105, avoiding the air flow being too dispersed to pass through the condenser 105 more, thereby further ensuring the heat dissipation effect of the condenser 105. At the same time, the slope of the inclined section 114 guides the outgoing air flow of the bottom air outlet 110b towards the front side of the ground air outlet, making the outgoing air flow flow out of the compressor compartment more smoothly, thereby further improving the smoothness of the air flow.

[0093] Further 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 guiding and rectifying effect on the air flow.

[0094] Moreover, unexpectedly, the inventor of the present application creatively realizes that the slope of the inclined section 114 has a good inhibitory effect on the air flow noise. In the prototype test, the noise of the compressor compartment with the specially designed inclined section 114 can be reduced by more than 0.65 decibels.

[0095] In addition, in the conventional refrigerator 100, the bottom of the refrigerator 100 generally has a bearing plate with a substantially flat plate structure, and the compressor 104 is arranged inside the bearing plate. The vibration generated during the operation of the compressor 104 has a greater impact on the bottom of the cabinet 100. In this embodiment, as described above, the bottom of the refrigerator 100 is constructed as a three-dimensional structure by the bottom plate and the support plate 112 with special structures, providing an independent three-dimensional space for the layout of the compressor 104. The support plate 112 is used to carry the compressor 104, reducing the impact of the vibration of the compressor 104 on other components at the bottom of the cabinet 100. In addition, by designing the refrigerator 100 into the above-mentioned ingenious special structure, the structure at the bottom of the refrigerator 100 is compact and reasonably arranged, reducing the overall volume of the refrigerator 100, while fully utilizing the space at the bottom of the refrigerator 100 and ensuring the heat dissipation efficiency of the compressor 104 and the condenser 105.

[0096] Further specifically, a wind blocking member 1056 is provided at the upper end of the condenser 105. The wind blocking member 1056 can be a wind blocking sponge, filling the space between the upper end of the condenser 105 and the bent section. That is to say, the wind blocking member 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 blocking member 1056 should be in contact with the bent section to seal the upper end of the condenser 105, so as to prevent some of the air entering the compressor compartment from passing through the space between the upper end of the condenser 105 and the bent section without passing through the condenser 105, so that as much air as possible entering the compressor compartment passes through the condenser 105 for heat exchange, further improving the heat dissipation effect of the condenser 105.

[0097] In some embodiments, the refrigerator 100 further includes a wind blocking strip 107 extending in the front-rear direction. The wind blocking strip 107 is 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 connecting the lower end of the partition member 117, so as to completely isolate the bottom air inlet 110a and the bottom air outlet 110b by using the wind blocking strip 107 and the partition member 117. Thus, when the refrigerator 100 is placed on a support surface, the space between the bottom wall of the refrigerator 100 and the support surface is horizontally partitioned, allowing external air to enter the compressor compartment through the bottom air inlet 110a on the lateral side of the wind blocking strip 107 under the action of the heat dissipation fan 106, flowing through the condenser 105 and the compressor 104 in sequence, and finally flowing out from the bottom air outlet 110b on the lateral side of the wind blocking strip 107, thereby completely isolating the bottom air inlet 110a and the bottom air outlet 110b, ensuring that the external air entering the condenser 105 and the heat dissipation air discharged from the compressor 104 will not flow into each other, and further ensuring the heat dissipation efficiency.

[0098] At this point, those skilled in the art should recognize that although numerous 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 from the disclosed content of 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 such other variations or modifications.
