[0035] It should be understood by those skilled in the art that the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments of the present invention, and the embodiments are intended to explain the technical principles of the present invention, rather than to limit the protection scope of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should still fall within the protection scope of the present invention.

[0036] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "top", "bottom", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0037] Furthermore, it should be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "install", "connect", and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances. For example, the terms "install", "connect", "connect" and "fix", unless otherwise specifically described, can specifically be any feasible connection form such as bolt connection, screw connection, welding, plug-in, riveting, melting, and clamping.

A certain target object stores "cold" or "heat" in order to keep the current temperature of the target object. "Refrigeration" and "heat absorption" are two descriptions of the same physical phenomenon, that is, a certain target object (such as an evaporator) will absorb heat while cooling.

[0039] like Figure 1 As shown, in the present invention, the refrigerator includes a box body 100 and a refrigeration system 200, wherein the refrigeration system 200 is used to provide cold energy to the refrigerator.

[0040] like Figures 2 to 4 As shown, in some embodiments of the present invention, the box body 100 defines a first storage compartment 111 and a second storage compartment 112.

[0044] Those skilled in the art will appreciate that the first circuit 101 enables air to circulate between the first side wall space 121 and the first storage compartment 111 , and the second circuit 102 enables air to circulate between the second side wall space 122 and the second storage compartment 112 .

[0045] like Figures 3 to 6 As shown, the first circuit 101 includes a first air supply channel 131 and a first air return port 141. At least a portion of the first air supply channel 131 is located at the rear side of the first side wall space 121 and is used to connect the first side wall space 121 and the first storage compartment 111. The first air return port 141 is formed on the side wall between the first side wall space 121 and the first storage compartment 111. The first storage compartment 111 is connected to the first air supply channel 131 through a first air outlet 1111 formed at the rear side thereof.

[0046] Furthermore, the first air supply channel 131 may be formed at the rear side of the first side wall space 121 and the first storage compartment 111; the first air return port 141 may be formed as Figure 3 and Figure 4 The first air return port 141 is formed at the front portion of the side wall between the first side wall space 121 and the first storage compartment 111. That is, the first air return port 141 is disposed at a position of the first storage compartment 111 close to the corresponding door 330 thereof.

[0047] Continue reading Figures 3 to 6The second circuit 102 includes a second air supply channel 132 and a second air return port 142. At least a portion of the second air supply channel 132 is located at the rear side of the second side wall space 122 and is used to connect the second side wall space 122 and the second storage compartment 112. The second air return port 142 is formed on the side wall between the second side wall space 122 and the second storage compartment 112. The second storage compartment 112 is connected to the second air supply channel 132 through a second air outlet 1121 formed at the rear side thereof.

[0048] Furthermore, the second air supply channel 132 may be formed at the rear side of the second side wall space 122 and the second storage compartment 112; the second air return port 142 may be formed as shown in FIG. Figure 3 and Figure 4 The second air return port 142 is formed at the front portion of the side wall between the second side wall space 122 and the second storage compartment 112. That is, the second air return port 142 is disposed at a position of the second storage compartment 112 close to the corresponding door 330 thereof.

[0049] like Figures 3 to 6 As shown, in some embodiments of the present invention, the refrigerator further includes a first evaporator 211 arranged in the first side wall space 121 and a second evaporator 212 arranged in the second side wall space 122. The first evaporator 211 is used to cool the air in the first side wall space 121, and the second evaporator 212 is used to cool the air in the second side wall space 122.

[0050] Furthermore, in some embodiments of the present invention, the first evaporator 211 and the second evaporator 212 may both be flat plate evaporators to reduce the transverse thickness of the first evaporator 211 and the second evaporator 212. In addition, those skilled in the art may also configure the first evaporator 211 and the second evaporator 212 as evaporators formed only by bending the refrigerant pipe as needed.

[0051] Continue reading Figures 3 to 6 In some embodiments of the present invention, the refrigerator further comprises a first fan 311 and a second fan 312. The first fan 311 is used to drive the air in the first circuit 101 to circulate, so that the cold air in the first side wall space 121 enters the first storage compartment 111 to refrigerate the first storage compartment 111; the second fan 312 is used to drive the air in the second circuit 102 to circulate, so that the cold air in the second side wall space 122 enters the second storage compartment 112 to refrigerate the second storage compartment 112.

[0052] from Figure 6It can be seen that the first fan 311 is arranged on the path of air flow in the first air supply channel 131, and the second fan 312 is arranged on the path of air flow in the second air supply channel 132. In addition, the first fan 311 and the second fan 312 can each be a centrifugal fan, an axial flow fan, a cross-flow fan, or any other feasible fan.

[0053] like Figure 4 and Figure 6 As shown, in some embodiments of the present invention, the refrigerator further comprises a damper 340, and the damper 340 is used to selectively block the communication between the first circuit 101 and the second circuit 102. Further, the damper 340 is arranged at the connection between the first circuit 101 and the second circuit 102.

[0054] from Figure 4 and Figure 6 It can be seen that the first circuit 101 and the second circuit 102 can be connected through the first air supply channel 131 and the second air supply channel 132, so the damper 340 can be set at the connecting point between the first air supply channel 131 and the second air supply channel 132.

[0055] Those skilled in the art will appreciate that when the damper 340 is closed, the first circuit 101 and the second circuit 102 are isolated, and the air in the first circuit 101 and the second circuit 102 circulates in their respective circuits without interfering with each other. When the damper 340 is opened, the first circuit 101 and the second circuit 102 are connected, and the air in the first circuit 101 and the second circuit 102 can be mixed with each other to exchange cold.

[0056] In addition, in order to allow one of the first evaporator 211 and the second evaporator 212 to simultaneously cool the first storage compartment 111 and the second storage compartment 112, those skilled in the art may also provide ventilation holes on the side wall between the first storage compartment 111 and the second storage compartment 112 as needed, so that the air in both the first storage compartment 111 and the second storage compartment 112 can circulate.

[0057] like Figure 3 and Figure 5 As shown, in some embodiments of the present invention, the refrigerator further includes a first baffle 321 for shielding the first return air outlet 141 and a second baffle 322 for shielding the second return air outlet 142. The first baffle 321 is used to shield the first return air outlet 141 when the first evaporator 211 is defrosted to prevent heat from entering the first storage compartment 111. The second baffle 322 is used to shield the second return air outlet 142 when the second evaporator 212 is defrosted to prevent heat from entering the second storage compartment 112.

[0058] In the present invention, the damper 340 , the first baffle 321 , and the second baffle 322 may each be an electrically controlled component, and further may be an electrically controlled sliding structure or an electrically controlled flipping structure.

[0059] like Figure 5 As shown, in some embodiments of the present invention, a water receiving tray 410 is arranged in the first side wall space 121 and the second side wall space 122, respectively, and the water receiving tray 410 is used to receive condensation water or defrost water flowing down from the first evaporator 211 and the second evaporator 212. The water receiving tray 410 is connected to a drain pipe 420, and the drain pipe 420 is away from the water receiving tray 410 and leads to the press chamber of the refrigerator to guide the water in the water receiving tray 410 to the evaporation dish in the press chamber.

[0060] like Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, in some embodiments of the present invention, the box body 100 may further define a third storage compartment 113, and the third storage compartment 113 may be located above the first storage compartment 111 and the second storage compartment 112. Alternatively, those skilled in the art may also make the third storage compartment 113 located below the first storage compartment 111 and the second storage compartment 112 as required.

[0061] Furthermore, the cabinet 100 is further defined with a refrigeration space 151, and a third air supply passage 152 and a third air return port 153 connecting the refrigeration space 151 with the third storage compartment 113. The third storage compartment 113 is connected with the third air supply passage 152 through a third air outlet 1131 formed at the rear side thereof. A third evaporator 213 is arranged in the refrigeration space 151. In addition, the refrigerator further includes a third fan 313 arranged in the refrigeration space 151 or the third air supply passage 152, so that the air circulates between the refrigeration space 151 and the third storage compartment 113 under the drive of the third fan 313, so as to cool the third storage compartment 113.

[0062] like Figure 8 As shown, in some embodiments of the present invention, the refrigeration system 200 includes a compressor 220, a condenser 230, a first control valve 241, a first throttling member 251, a first evaporator 211 and a second control valve 242 which are connected end to end to form a loop.

[0063] Furthermore, the refrigeration system 200 further includes a second throttling member 252 , a second evaporator 212 , and a third control valve 243 connected in series between the first control valve 241 and the compressor 220 .

[0064] One outlet of the second control valve 242 is connected to the inlet fluid of the second evaporator 212 , and one outlet of the third control valve 243 is connected to the inlet fluid of the first evaporator 211 .

[0065] Furthermore, the refrigeration system 200 further includes a third throttling member 253 and a third evaporator 213 connected in series between the first control valve 241 and the compressor 220. The outlet of the third evaporator 213 may be fluidly connected to an inlet of the third control valve 243, or directly connected to the inlet of the compressor 220.

[0066] The first throttling member 251, the second throttling member 252 and the third throttling member 253 can each be a capillary tube or an electronic expansion valve. The first control valve 241, the second control valve 242 and the third control valve 243 can each be a multi-way reversing valve or a plurality of parallel two-way valves or stop valves.

[0067] Continue reading Figure 8 The refrigerator further includes a first heating device 510 for heating the first evaporator 211 and a second heating device 520 for heating the second evaporator 212. When the first evaporator 211 is defrosted, the first evaporator 211 is heated by the first heating device 510; when the second evaporator 212 is defrosted, the second evaporator 212 is heated by the second heating device 520.

[0068] In some embodiments of the present invention, the first storage compartment 111, the second storage compartment 112 and the third storage compartment 113 can be used as a refrigerating compartment or a freezing compartment, respectively.

[0069] Whether the third storage compartment 113 is used as a freezing compartment or a refrigerating compartment, when refrigeration is required, the first control valve 241 is controlled to allow the refrigerant flowing therethrough to flow to the third throttling member 253. At the same time, the third fan 313 is started.

[0070] When the first storage compartment 111 and the second storage compartment 112 are both used as a freezing compartment or a refrigerating compartment and both need refrigeration, the first control valve 241 is controlled so that the refrigerant flowing therethrough simultaneously flows to the first throttling member 251 and the second throttling member 252. At this time, the second control valve 242 is controlled so that only the outlet of the first evaporator 211 is connected to the inlet of the compressor 220, and the third control valve 243 is controlled so that only the outlet of the second evaporator 212 is connected to the inlet of the compressor 220. At the same time, the first fan 311 and the second fan 312 are started.

[0071] It should be noted that the rotation speeds of the first fan 311 and the second fan 312 when the first storage compartment 111 and the second storage compartment 112 are both used as freezing compartments are greater than the rotation speeds when the first storage compartment 111 and the second storage compartment 112 are both used as refrigerating compartments.

[0072] When the first storage compartment 111 is used as a freezing compartment and the second storage compartment 112 is used as a refrigerating compartment, the first control valve 241 is controlled so that the refrigerant flowing therethrough flows only to the first throttling member 251 of the first throttling member 251 and the second throttling member 252. At this time, the second control valve 242 is controlled so that only the outlet of the first evaporator 211 is connected to the inlet of the second evaporator 212, and the second control valve 242 is controlled so that only the outlet of the second evaporator 212 is connected to the inlet of the compressor 220. At the same time, the first fan 311 and the second fan 312 are started.

[0073] During this process, if the second storage compartment 112 is switched from the refrigerating compartment to the freezing compartment, the damper 340 is controlled to open so that the low-temperature cold air flowing out of the first side wall space 121 is mixed with the high-temperature cold air flowing out of the second side wall space 122 to achieve rapid cooling of the second storage compartment 112.

[0074] When the first storage compartment 111 is used as a refrigerating compartment and the second storage compartment 112 is used as a freezing compartment, the first control valve 241 is controlled so that the refrigerant flowing therethrough only flows to the second throttling member 252 of the first throttling member 251 and the second throttling member 252. At this time, the second control valve 242 is controlled so that only the outlet of the first evaporator 211 is connected to the inlet of the compressor 220, and the second control valve 242 is controlled so that only the outlet of the second evaporator 212 is connected to the inlet of the first evaporator 211. At the same time, the first fan 311 and the second fan 312 are started.

[0075] During this process, if the first storage compartment 111 is switched from the refrigerating compartment to the freezing compartment, the damper 340 is controlled to open so that the high-temperature cold air flowing out of the first side wall space 121 is mixed with the low-temperature cold air flowing out of the second side wall space 122 to achieve rapid cooling of the first storage compartment 111.

[0076] In summary, the refrigerator of the present invention avoids disposing the first evaporator 211 and the second evaporator 212 at the rear sides of the first storage compartment 111 and the second storage compartment 112 while ensuring that the first storage compartment 111 and the second storage compartment 112 can be refrigerated, thereby increasing the depth of the first storage compartment 111 and the second storage compartment 112.

[0077] At the same time, the refrigeration system 200 of the refrigerator of the present invention also enables the first storage compartment 111 and the second storage compartment 112 to be freely converted between a refrigerating compartment and a freezing compartment, thereby improving the user experience.

[0078] So far, the technical solution of the utility model has been described in combination with the above multiple embodiments, but it is easy for those skilled in the art to understand that the protection scope of the utility model is not limited to these specific embodiments. Without departing from the technical principle of the utility model, those skilled in the art can split and combine the technical solutions in the above embodiments, and can also make equivalent changes or replacements to the relevant technical features. Any changes, equivalent replacements, improvements, etc. made within the technical concept and / or technical principle of the utility model will fall within the protection scope of the utility model.

[0079] Finally, it should be noted that the refrigerator of the present invention is a refrigerator in a broad sense, which not only includes the so-called refrigerator in a narrow sense, but also includes fresh-keeping equipment with refrigeration and / or freezing functions, such as refrigerators, freezers, etc.

[0080] In the present invention, the term "communication" means fluid communication, so as to allow fluid (such as air, liquid) to flow between two connected objects. And the "communication" can be to allow the fluid to flow between the two connected objects without leakage, or to allow the fluid to flow between the two connected objects with a little leakage.
