Description

Technical Field

[0001] This invention relates to the field of refrigeration, and in particular to a detachable, air-cooled refrigeration appliance. Background Technology

[0002] Currently, refrigeration appliances are being used more and more widely. Refrigeration appliances that are suitable for diverse usage scenarios and are relatively easy to move, such as car refrigerators, have emerged as a result.

[0003] It is known that cooling can be achieved using semiconductor refrigeration principles or through direct cooling cycles, thus providing miniaturized refrigeration appliances. These miniaturized refrigerators are small in size and easy to move, but often have poor cooling performance. Summary of the Invention

[0004] The purpose of embodiments of the present invention is to provide an improved refrigeration appliance that overcomes at least one of the aforementioned deficiencies of the prior art.

[0005] According to a first aspect of the present invention, embodiments of the present invention provide an air-cooled detachable refrigeration appliance, comprising: a storage module including a storage box having a storage space and a storage air supply interface and a storage air return interface communicating with the storage space; and a refrigeration module including a refrigeration component, a refrigeration air supply interface for supplying air cooled by the refrigeration component to the storage module, and a refrigeration air return interface for receiving air returning from the storage module. The storage module and the refrigeration module are detachably connected such that the storage air supply interface and the storage air return interface are detachably connected to the refrigeration air supply interface and the refrigeration air return interface, respectively.

[0006] Therefore, a split-type air-cooled refrigeration appliance can be provided. When the refrigeration appliance is connected, the storage module can be connected to the refrigeration module so that the refrigeration module can quickly cool the storage space using air cooling. Air cooled by the refrigeration components can be supplied to the storage space of the storage module through interconnected refrigeration air supply interfaces and storage air supply interfaces. Air returning from the storage module can be returned to the refrigeration components of the refrigeration module through interconnected storage return air interfaces and refrigeration return air interfaces. When the refrigeration appliance is disconnected, the storage module can also be easily separated from the refrigeration module, and the storage module and the cooled items contained within it can be moved independently. This makes the refrigeration appliance both highly efficient and flexible enough to be used in various scenarios.

[0007] According to an optional embodiment of the present invention, the storage module may include an automatic sealing structure located at the storage air supply interface and / or storage return interface. The automatic sealing structure is configured to close the openings of the storage air supply interface and / or storage return interface in a closed state and to open the openings of the storage air supply interface and / or storage return interface in an open state. The automatic sealing structure is moved to an open state by the corresponding cooling air supply interface and / or cooling return interface when connected to the storage air supply interface and / or storage return interface, and automatically moves to a closed state when the corresponding cooling air supply interface and / or cooling return interface is separated from the storage air supply interface and / or storage return interface.

[0008] When the storage module is connected to the refrigeration module, the automatic sealing structure automatically moves to the open state and remains open under the drive of the refrigeration air supply interface and / or refrigeration return interface, requiring no additional operation. When the storage module is disconnected from the refrigeration module, the automatic sealing structure automatically moves to the closed state, also requiring no additional operation. Thanks to the automatic sealing structure, gas exchange between the storage space and the external environment via the storage air supply interface and / or storage return interface is prevented when the refrigeration appliance is disconnected. Therefore, even when the storage module is disconnected from the refrigeration module, the storage space can maintain a low temperature for a longer period of time. The automatic sealing structure particularly simplifies operation.

[0009] According to an optional embodiment of the invention, the automatic sealing structure may include a sealing element and a biasing element. The sealing element is rotatably arranged such that it can rotate between a closed position, where the openings of the storage air supply inlet and / or storage return inlet are closed, and an open position, where the openings of the storage air supply inlet and / or storage return inlet are open. The biasing element may be arranged to bias the sealing element toward the closed position. Thus, an easy-to-implement and reliable automatic sealing structure can be achieved.

[0010] According to an optional embodiment of the invention, the automatic sealing structure may be arranged within the storage air supply interface and / or storage return air interface. The corresponding cooling air supply interface and / or cooling return air interface may be configured to be inserted into the storage air supply interface and / or storage return air interface, thereby pushing the seal to the open position and maintaining it in the open position. This implementation eliminates the need for electrical drive or electrical signal actuation of the automatic sealing structure. This is particularly advantageous in detachable refrigeration appliances.

[0011] According to an optional embodiment of the invention, the cooling air supply interface and / or cooling air return interface may be configured to be correspondingly inserted into the storage air supply interface and / or storage air return interface, which may be located within the wall of the storage box and not protrude outward relative to the wall of the storage box. This facilitates a sealed connection between the cooling air supply interface and / or cooling air return interface and the storage air supply interface and / or storage air return interface in the connected state; while in the disassembled state, this helps ensure that the storage module has a shape that facilitates individual movement and use.

[0012] According to an optional embodiment of the present invention, the refrigeration module may include a support base for supporting the storage module and a refrigeration compartment for accommodating the refrigeration components. Thus, the entire refrigeration appliance can be moved simply by moving the refrigeration module. The refrigeration appliance is also easily movable when connected.

[0013] According to an optional embodiment of the invention, the refrigeration compartment is located at one end of the support base, causing the refrigeration module to be L-shaped. When the storage module is connected to the refrigeration module, the storage module is located on the support base and arranged side-by-side with the refrigeration compartment. This allows the refrigeration appliance to have a stable and compact configuration when connected.

[0014] According to an optional embodiment of the invention, the storage air supply interface and storage return air interface, along with the cooling air supply interface and cooling return air interface, can be configured to be interconnected along the connection direction. The support base may have a guide groove extending along the connection direction on its upper surface. The storage module may include a guide member for cooperating with the guide groove, the guide member being configured to move within the guide groove along the connection direction. This facilitates a more convenient and reliable connection between the storage module and the cooling module. Simultaneously, the cooperation between the guide member and the guide groove prevents displacement of the storage module relative to the cooling module.

[0015] According to an optional embodiment of the invention, the width of the guide groove may be narrowed in the direction toward the refrigeration compartment along the connection direction. Thus, during the process of connecting the storage module to the refrigeration module, as the guide moves within the guide groove along the connection direction, the fit between the guide and the guide groove becomes increasingly tight until the storage module is reliably connected to the refrigeration module.

[0016] According to an optional embodiment of the invention, the depth of the guide groove can be increased in the direction along the connection direction toward the refrigeration compartment. This prevents the storage module from accidentally detaching from the refrigeration module by means of gravity. In particular, the depth of the guide groove can be large enough that the storage box is directly supported on the support base when the refrigeration appliance is connected. This helps to stably maintain the connection state of the refrigeration appliance and prevents the storage module from accidentally detaching from the refrigeration module.

[0017] According to an alternative embodiment of the invention, the guide groove may have an end wall that closes the guide groove in a direction away from the refrigeration chamber along the connection direction.

[0018] The end wall can be configured to block the guide within the guide slot, thereby preventing the storage module from detaching from the refrigeration module. The end wall allows for limiting the position of the storage module while the refrigeration appliance is connected.

[0019] The end walls can be arranged at an angle to form a ramp. This makes it easier to connect and disconnect the storage modules.

[0020] According to an optional embodiment of the present invention, the guide may include a second roller capable of rolling within a guide groove in the connection direction. The second roller facilitates both the connection and disconnection operations of the storage module and makes the storage module more portable.

[0021] According to an optional embodiment of the invention, the support base may have an upwardly projecting locking hook at the end away from the refrigeration compartment. The storage box may have a locking recess on the side opposite to the refrigeration compartment. When the storage module is connected to the refrigeration module, the locking hook is engaged in the locking recess by a snap-fit ​​connection, thereby locking the connection between the storage module and the refrigeration module.

[0022] According to an optional embodiment of the invention, the refrigeration module may include first rollers, such that when the storage module is connected to the refrigeration module, the refrigeration appliance can be entirely supported by the first rollers. This facilitates the movement of the refrigeration module and the refrigeration appliance as a whole.

[0023] Optionally, the refrigeration module may include a telescopic rod. In particular, the combination of the rod and the first roller enables the refrigeration appliance to be easily moved.

[0024] Optionally, the storage module may include a second roller, allowing the storage module to be supported by the second roller. This makes it easy to move the individual storage module.

[0025] According to an optional embodiment of the present invention, the storage box may have a bottom wall, a first side wall and a second side wall opposite to each other, and a third side wall and a fourth side wall opposite to each other, the bottom wall, the first side wall, the second side wall, the third side wall and the fourth side wall surrounding the storage space.

[0026] Storage air supply and return ports can be located, for example, on the side wall of the first compartment.

[0027] Optionally, the storage unit has an air outlet on its inner side facing the storage space for introducing air from the storage air supply interface and a return air inlet for leading air from the storage space to the storage return air interface. The air outlet is located on the side wall of the first unit, and the return air inlet is located on the side wall of the second unit. Thus, the air outlet and return air inlet are arranged far apart from each other. This also helps to improve cooling efficiency.

[0028] Optionally, the storage module includes an L-shaped storage return air duct that extends within the side and bottom walls of the second compartment. This storage return air duct allows recirculated air to be guided from the return air inlet on the side wall of the second compartment to the storage air supply inlet on the side wall of the first compartment.

[0029] According to an optional embodiment of the invention, the storage box may have an air outlet for introducing air from the storage air supply interface, a return air outlet for leading air to the storage return air interface, and a baffle on the inner side facing the storage space. The baffle may be arranged above the air outlet and / or return air outlet and protrude downwards into the storage space. The baffle prevents condensate adhering to the inner side of the storage box from flowing into the air outlet and / or return air outlet.

[0030] According to an optional embodiment of the invention, the obstruction eaves include an eaves top wall located above the respective air outlet and / or return air inlet and two eaves side walls located on opposite sides of the respective air outlet and / or return air inlet, such that the obstruction eaves surround the respective air outlet and / or return air inlet from above and from both sides. This effectively prevents condensate from flowing into the air outlet and / or return air inlet.

[0031] According to an optional embodiment of the invention, the refrigeration assembly includes a compressor, a condenser, and an evaporator interconnected to form a refrigerant circuit, and the refrigeration module includes a fan for generating airflow from the evaporator to the refrigeration air inlet, the fan being arranged between the evaporator and the refrigeration air inlet. This helps to promote sufficient contact between the returning air and the evaporator and helps to prevent water or ice carried by the airflow from the evaporator from entering the refrigeration air inlet.

[0032] According to an optional embodiment of the invention, the refrigeration module may include a first fan housing disposed on the side of the fan facing away from the evaporator. The first fan housing has a guide wall extending around the fan on the fan-facing side, and a refrigerated air inlet is formed on the fan-facing side of the first fan housing. This first fan housing can efficiently supply cooled air to the refrigerated air inlet and simplifies the manufacturing and assembly process.

[0033] Alternatively or additionally, the refrigeration module may include a second fan housing disposed on the side of the fan facing the evaporator. The second fan housing is formed in a basin shape to define a pressure chamber within which the fan is at least partially housed. The second fan housing may optionally have an air inlet opening towards the evaporator. By means of the pressure chamber, the fan can drive air in a desired direction toward the refrigeration air inlet. This helps to improve efficiency.

[0034] According to an optional embodiment of the invention, the refrigeration module includes a fan baffle disposed between the fan and the evaporator to block all straight paths of airflow between the fan and the evaporator. The fan baffle effectively prevents water or ice carried by the airflow from the evaporator from approaching the fan.

[0035] According to an optional embodiment of the invention, the refrigeration module may include a second fan housing and a fan blocker. The second fan housing is disposed on the side of the fan facing the evaporator. The second fan housing is formed in a basin shape to define a pressure chamber in which the fan is at least partially housed. The second fan housing has an air inlet that opens toward the evaporator. The fan blocker may be spaced apart from the second fan housing on the side of the second fan housing facing the evaporator and completely blocks the air inlet in the direction toward the evaporator.

[0036] According to an optional embodiment of the present invention, the refrigeration assembly may include a compressor, a condenser, and an evaporator interconnected to form a refrigerant circuit, and the refrigeration module includes a refrigeration chamber for housing the refrigeration assembly, the refrigeration chamber having a first chamber in which the evaporator is disposed.

[0037] According to an optional embodiment of the invention, the bottom surface of the first chamber may include a first bottom surface portion, a second bottom surface portion offset downward relative to the first bottom surface portion, and a connecting bottom surface portion connecting the first bottom surface portion and the second bottom surface portion, thereby forming a recessed portion above the second bottom surface portion that is concave downward relative to the first bottom surface portion. The second bottom surface portion is further away from the storage module than the first bottom surface portion. An evaporator may be arranged above the first bottom surface portion and cover the recessed portion. The inlet of the first chamber may be located at the connecting bottom surface portion and connected to the refrigeration return air interface via a refrigeration return air duct. This helps ensure that the return air is adequately cooled by the evaporator. Simultaneously, the refrigeration chamber has a compact and easy-to-install structure.

[0038] According to an optional embodiment of the invention, the refrigeration chamber may have a second compartment in which the compressor and condenser are arranged. The first and second compartments may be arranged vertically to each other and separated from each other by means of insulation. This helps to improve refrigeration efficiency.

[0048] To make the technical problems to be solved, the technical solutions, and the beneficial technical effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of protection of this invention.

[0049] First, for ease of understanding, let's return to the description in the background section. Existing refrigeration appliances suffer from problems such as being inconvenient to carry, having low refrigeration efficiency, being complex to operate, and / or being inconvenient to use.

[0050] To address at least one of the aforementioned technical problems or other possible technical problems, an exemplary embodiment of the present invention provides an air-cooled detachable refrigeration appliance, comprising: a storage module including a storage box having a storage space and a storage air supply interface and a storage air return interface communicating with the storage space; and a refrigeration module including a refrigeration component, a refrigeration air supply interface for supplying air cooled by the refrigeration component to the storage module, and a refrigeration air return interface for receiving air returning from the storage module. The storage module and the refrigeration module are detachably connected, such that the storage air supply interface and the storage air return interface are detachably connected to the refrigeration air supply interface and the refrigeration air return interface, respectively.

[0051] To better understand the present invention, exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0052] Before proceeding with the detailed description, it should be noted that the directional terms used in the description refer to the refrigerator's normal operating conditions for ease of description, and should not be interpreted as absolute limitations on the corresponding characteristics.

[0053] Figure 1 and Figure 2 A refrigeration appliance according to an exemplary embodiment of the present invention is illustrated schematically.

[0054] The refrigeration appliance is a detachable, air-cooled refrigeration appliance, comprising a storage module 1 and a refrigeration module 2. The storage module 1 includes a storage box 11 with a storage space 110 (not visible here), and a storage air supply interface 121 and a storage air return interface 122 connected to the storage space 110. The refrigeration module 2 includes a refrigeration component 21 (not visible here), a refrigeration air supply interface 221 for supplying air cooled by the refrigeration component 21 to the storage module 1, and a refrigeration air return interface 222 for receiving air returning from the storage module 1. The storage module 1 and the refrigeration module 2 are detachably connected, such that the storage air supply interface 121 and the storage air return interface 122 are detachably connected to the refrigeration air supply interface 221 and the refrigeration air return interface 222, respectively. Figure 1 The storage module 1 is shown connected to the cooling module 2. Figure 2 The storage module 1 and the refrigeration module 2 are shown to be separate.

[0055] Therefore, a split-type air-cooled refrigeration appliance can be provided. When the refrigeration appliance is connected, the storage module 1 can be connected to the refrigeration module 2 so that the refrigeration module 2 can quickly cool the storage space 110 using air cooling. Air cooled by the refrigeration component 21 can be supplied to the storage space 110 of the storage module 1 via the interconnected refrigeration air supply interface 221 and storage air supply interface 121. Air returning from the storage module 1 can be returned to the refrigeration component 21 of the refrigeration module 2 via the interconnected storage return air interface 122 and refrigeration return air interface 222. When the refrigeration appliance is disconnected, the storage module 1 can also be easily separated from the refrigeration module 2, and the storage module 1 and the cooled items contained therein can be moved independently. This makes the refrigeration appliance both highly efficient and flexible enough to be used in various scenarios.

[0056] In this embodiment, the refrigeration appliance is a refrigerator. Those skilled in the art will understand that the present invention is also applicable to other types of refrigeration appliances, such as freezers or wine coolers.

[0057] The refrigeration appliance can be configured as a vehicle refrigerator. For example, an air-cooled detachable refrigeration appliance according to an exemplary embodiment of this application can be installed in a motorhome.

[0058] As an example, in the detached state of the refrigeration appliance, the storage module 1 can be separated from the refrigeration module 2 and placed separately in the storage compartment of the household refrigerator.

[0059] According to an exemplary embodiment of this application, the cooling air supply interface 221 and / or the cooling air return interface 222 may be configured to be correspondingly inserted into the storage air supply interface 121 and / or the storage air return interface 122. The storage air supply interface 121 and / or the storage air return interface 122 may be located within the wall of the storage box 11 and not protrude outward relative to the wall of the storage box 11. This facilitates the formation of a sealed connection between the cooling air supply interface 221 and / or the cooling air return interface 222 and the storage air supply interface 121 and / or the storage air return interface 122 in the connected state; while in the disassembled state, this helps to ensure that the storage module 1 has an shape that facilitates individual movement and use.

[0060] Figure 3 A cross-sectional view of a refrigeration appliance according to an exemplary embodiment of the present application is shown schematically. Figure 4 A cross-sectional view of a storage module 1 of a refrigeration appliance according to an exemplary embodiment of the present application is shown schematically.

[0061] from Figure 3 As can be seen, in the connected state, the cooling air supply interface 221 and the cooling return air interface 222 are inserted into the storage air supply interface 121 and the storage return air interface 122.

[0062] Figure 3 and Figure 4 It is also shown that the storage module 1 may include an automatic sealing structure 13 located at the storage air supply interface 121 and / or the storage return air interface 122. The automatic sealing structure 13 is configured to correspondingly close the openings of the storage air supply interface 121 and / or the storage return air interface 122 in a closed state (see [link to documentation]). Figure 4 ), and in the open state, the openings of the storage air supply interface 121 and / or the storage air return interface 122 are open (see Figure 3 The automatic closing structure 13 is moved to the open state by the corresponding cooling air supply interface 221 and / or cooling return air interface 222 when connected to the storage air supply interface 121 and / or storage return air interface 122, and automatically moves to the closed state when the corresponding cooling air supply interface 221 and / or cooling return air interface 222 is separated from the storage air supply interface 121 and / or storage return air interface 122. Here, "moved" can mean translation and / or rotation.

[0063] When the storage module 1 is connected to the refrigeration module 2, the automatic sealing structure 13 can automatically move to the open state and remain open under the drive of the refrigeration air supply interface 221 and / or the refrigeration return air interface 222, without any additional operation. When the storage module 1 is disconnected from the refrigeration module 2, the automatic sealing structure 13 can automatically move to the closed state, also without any additional operation. With the help of the automatic sealing structure 13, gas exchange between the storage space 110 and the external environment via the storage air supply interface 121 and / or the storage return air interface 122 can be prevented when the refrigeration appliance is disconnected. Therefore, even when the storage module 1 is disconnected from the refrigeration module 2, the storage space 110 can still maintain a low temperature for a longer period of time. The automatic sealing structure 13 provides a particularly advantageous way to simplify operation.

[0064] Figure 5 and Figure 6 They are shown schematically respectively. Figure 3 and Figure 4 An enlarged view of the circled portion.

[0065] like Figure 5 and Figure 6 As shown, the automatic closing structure 13 may include a closing member 131 and a biasing element 132. The closing member 131 is rotatably arranged such that it can rotate between a closed position, closing the openings of the storage air supply interface 121 and / or the storage air return interface 122, and an open position, opening the openings of the storage air supply interface 121 and / or the storage air return interface 122. The biasing element 132 is arranged to bias the closing member 131 toward the closed position. The biasing element 132 may, in particular, include a spring, such as a torsion spring.

[0066] Optionally, the automatic closing structure 13 may be arranged within the storage air supply interface 121 and / or the storage return air interface 122. The corresponding cooling air supply interface 221 and / or cooling return air interface 222 may be configured to be inserted into the storage air supply interface 121 and / or the storage return air interface 122, thereby pushing the closure 131 to the open position and holding it in the open position.

[0067] Combination Figure 1 and Figure 2 As can be seen, the refrigeration module 2 may include a support base 23 for supporting the storage module 1 and a refrigeration chamber 24 for accommodating the refrigeration components 21. When the refrigeration appliance is connected, the storage module 1 is supported on the support base 23 of the refrigeration module 2. Therefore, the entire refrigeration appliance can be moved simply by moving the refrigeration module 2.

[0068] The refrigeration module 2 may include first rollers 251, such that when the storage module 1 is connected to the refrigeration module 2, the refrigeration appliance can be entirely supported by the first rollers 251. This facilitates the movement of the refrigeration module 2 and the refrigeration appliance as a whole. For example, four first rollers 251 may be arranged below the support base 23.

[0069] Alternatively or additionally, the refrigeration module 2 may include a telescopic rod 252. In particular, the combination of the rod 252 and the first roller 251 enables the refrigeration appliance to be easily moved. The rod 252 may be telescopic, for example, in the height direction. The rod 252 may be mounted on the refrigeration compartment 24.

[0070] Optionally, the storage module 1 may include a second roller 141, such that the storage module 1 can be supported by the second roller 141, see [reference]. Figure 4 This makes the individual storage module 1 easy to move.

[0071] exist Figure 1 and Figure 2 In the illustrated embodiment, the refrigeration appliance is a portable and mobile device, whether in the connected or disconnected state. The individual storage module 1, the individual refrigeration module 2, and the refrigeration appliance in the connected state are all easy to move.

[0072] The refrigeration compartment 24 can be positioned at one end of the support base 23, allowing the refrigeration module 2 to form an L-shape. When the storage module 1 is connected to the refrigeration module 2, the storage module 1 can be located on the support base 23 and arranged side-by-side with the refrigeration compartment 24. This allows the refrigeration appliance to have a stable and compact configuration when connected.

[0073] The storage air supply interface 121 and storage return air interface 122, and the cooling air supply interface 221 and cooling return air interface 222, can be configured to be interconnected along a connection direction D. The connection direction D extends, for example, horizontally. The support base 23 may have a guide groove 231 extending along the connection direction D on its upper surface. The storage module 1 includes a guide 14 for engaging with the guide groove 231, the guide 14 being configured to move within the guide groove 231 along the connection direction D. This facilitates a more convenient and reliable connection between the storage module 1 and the cooling module 2. Simultaneously, the engagement of the guide 14 with the guide groove 231 prevents displacement of the storage module 1 relative to the cooling module 2.

[0074] like Figure 2 As shown, the support base 23 may be provided with two parallel guide grooves 231. The guide grooves 231 may extend from the end of the support base 23 away from the refrigeration compartment 24 along the connection direction D to the refrigeration compartment 24.

[0075] Figure 7A and Figure 7B The refrigeration module 2 and storage module 1 of a refrigeration appliance according to an exemplary embodiment of the present application are shown schematically.

[0076] from Figure 7A The guide groove 231 can be seen more clearly. The guide groove 231 may have an end wall 2311 that closes the guide groove 231 in the direction away from the refrigeration compartment 24 along the connection direction D. The end wall 2311 may be configured to block the guide 14 within the guide groove 231 to prevent the storage module 1 from disengaging from the refrigeration module 2. By means of the end wall 2311, the storage module 1 can be limited in the connected state of the refrigeration appliance.

[0077] The end wall 2311 can be arranged at an angle to form a ramp. This makes it easier to connect and disconnect the storage module 1.

[0078] The guide 14 may include, for example, a second roller 141, which is capable of rolling within the guide groove 231 in the connection direction D. Thus, the second roller 141 facilitates both the connection and separation operations of the storage module 1 and makes the storage module 1 more portable.

[0079] Alternatively, the guide 14 may also include a slider that can slide within the guide groove 231 along the connection direction D.

[0080] According to an exemplary embodiment of this application, the width w of the guide groove 231 narrows in the direction along the connection direction D toward the refrigeration compartment 24. Therefore, during the process of connecting the storage module 1 to the refrigeration module 2, as the guide 14 moves within the guide groove 231 along the connection direction D, the fit between the guide 14 and the guide groove 231 becomes increasingly tight until the storage module 1 is reliably connected to the refrigeration module 2.

[0081] According to an exemplary embodiment of this application, the depth d of the guide groove 231 increases in the direction along the connection direction D toward the refrigeration compartment 24. This prevents the storage module 1 from accidentally detaching from the refrigeration module 2 by means of gravity. In particular, the depth d of the guide groove 231 can be large enough that the storage box 11 is directly supported on the support base 23 when the refrigeration appliance is connected. This helps to stably maintain the connected state of the refrigeration appliance and prevents the storage module 1 from accidentally detaching from the refrigeration module 2. For example, in the event of an impact or shaking of the refrigeration appliance, the storage module 1 will not accidentally detach from the refrigeration module 2 due to the rolling of the second roller 141.

[0082] Optionally, the support base 23 may have an upwardly protruding locking hook 232 at the end away from the refrigeration compartment 24. The storage box 11 may correspondingly have a locking recess 119 on the side opposite to the refrigeration compartment 24. When the storage module 1 is connected to the refrigeration module 2, the locking hook 232 can be engaged in the locking recess 119 by a snap-fit ​​connection to lock the connection between the storage module 1 and the refrigeration module 2.

[0083] from Figures 1 to 4 As can be seen, the storage box 11 may have a bottom wall 111, a first side wall 112 and a second side wall 113 opposite to each other, and a third side wall 114 and a fourth side wall 115 opposite to each other. The bottom wall 111, the first side wall 112, the second side wall 113, the third side wall 114, and the fourth side wall 115 surround the storage space 110. The storage box 11 may have a top opening through which a user can access items. The storage module 1 may also include a top cover for closing the top opening of the storage box 11. The top cover may, for example, be pivotally connected to the storage box 11.

[0084] The storage air supply interface 121 and the storage return air interface 122 can be arranged on the side wall 112 of the first box.

[0085] The storage box 11 may have an air outlet 116 for introducing air from the storage air supply interface 121 and a return air inlet 117 for leading air from the storage space 110 to the storage return air interface 122 on its inner side facing the storage space 110. The air outlet 116 may be arranged on the first box side wall 112, and the return air inlet 117 may be arranged on the second box side wall 113. Thus, the air outlet 116 and the return air inlet 117 are arranged far apart from each other.

[0086] The storage module 1 may include an L-shaped storage return air duct 15, which extends in the second box side wall 113 and the box bottom wall 111. By means of the storage return air duct 15, the returning air can be guided from the return air port 117 at the second box side wall 113 to the storage air supply port 121 at the first box side wall 112.

[0087] from Figures 3 to 6 As can be seen, the storage box 11 also has a baffle 118 on its inner side facing the storage space 110. The baffle 118 is arranged above the air outlet 116 and / or the return air inlet 117 and protrudes downwards into the storage space 110. The baffle 118 prevents condensate adhering to the inner side of the storage box 11 from flowing into the air outlet 116 and / or the return air inlet 117. If condensate forms and adheres to the inner side of the storage box 11, the condensate will flow downwards along the inner surface of the storage box 11 due to gravity and will be blocked by the baffle 118, flowing away along the top surface of the baffle 118. The condensate will not enter the air outlet 116 and / or the return air inlet 117, and therefore will not enter the wall of the storage box 11.

[0088] Figure 8 A portion of the first box sidewall 112 is shown schematically.

[0089] As can be seen, the obstruction eaves 118 are arranged above the air outlet 116. The obstruction eaves 118 may include an eaves top wall 1181 located above the air outlet 116 and two eaves side walls 1182 located on opposite sides of the air outlet 116, such that the obstruction eaves 118 surrounds the air outlet 116 from above and sides. The eaves top wall 1181 and the eaves side walls 1182 may, for example, extend from the upper edge and two side edges of the air outlet 116 and / or the return air inlet 117 toward the storage space 110. Thus, condensate can be effectively prevented from flowing into the air outlet 116 and / or the return air inlet 117.

[0090] The eaves wall 1181 can be arched. In a section parallel to the height direction and the opening direction of the air outlet 116, the eaves wall 1181 extends along a circular arc.

[0091] The obstruction 118 located above the return air inlet 117 may have the same construction.

[0092] Figure 9 An exploded view of the refrigeration module 2 of a refrigeration appliance according to an exemplary embodiment of the present application is shown schematically, wherein only some components are shown for clarity.

[0093] Combination Figure 3 and Figure 9As can be seen, the refrigeration assembly 21 may include a compressor 211, a condenser 212, and an evaporator 213 interconnected to form a refrigerant circuit. Other components, such as capillary tubes and expansion valves, may also be arranged in the refrigerant circuit. The refrigeration compartment 24 of the refrigeration module 2 may have a first chamber 241, and the evaporator 213 is arranged in the first chamber 241.

[0094] The refrigeration compartment 24 may also have a second compartment 242, in which the compressor 211 and condenser 212 are arranged. The first compartment 241 and the second compartment 242 may be arranged vertically relative to each other and separated by an insulation layer 243. This helps to improve refrigeration efficiency. The first compartment 241 may be surrounded by the insulation layer 243, which insulates the first compartment 241 from the second compartment 242 and the external environment.

[0095] See Figure 5 and Figure 9 The bottom surface of the first chamber 241 may include a first bottom surface portion 2411, a second bottom surface portion 2412 offset downward relative to the first bottom surface portion 2411, and a connecting bottom surface portion 2413 connecting the first bottom surface portion 2411 and the second bottom surface portion 2412, thereby forming a recessed portion 2414 that is concave downward relative to the first bottom surface portion 2411 above the second ground portion. The second bottom surface portion 2412 is further away from the storage module 1 than the first bottom surface portion 2411. The evaporator 213 may be arranged above the first bottom surface portion 2411 and cover the recessed portion 2414. The first chamber inlet 2415 may be located at the connecting bottom surface portion 2413 and connected to the cooling return air interface 222 via the cooling return air duct 29. This helps to ensure that the return air is adequately cooled by the evaporator 213. At the same time, the cooling chamber 24 has a compact and easy-to-install structure.

[0096] Evaporator 213 can, for example, substantially completely cover the recess 2414 from above. This further ensures that the returning air flows through evaporator 213.

[0097] The cooling return air duct 29 can be integrally constructed with the cooling return air interface 222 into a Z-shaped duct.

[0098] According to an exemplary embodiment of this application, the refrigeration module 2 may include a fan 26 for generating airflow from the evaporator 213 to the cooling air inlet 221. The fan 26 may be arranged between the evaporator 213 and the cooling air inlet 221. For example, the fan 26 may be located between the evaporator 213 and the cooling air inlet 221 in the connection direction D. Compared to a layout where the evaporator 213 is arranged between the fan 26 and the cooling air inlet 221, arranging the fan 26 between the evaporator 213 and the cooling air inlet 221 helps to promote sufficient contact between the returning air and the evaporator 213, and helps to prevent water or ice carried by the airflow from the evaporator 213 from entering the cooling air inlet 221.

[0099] Optionally, the cooling module 2 may include a first fan housing 271 and / or a second fan housing 272. Combined Figure 10 The first fan housing 271 and the second fan housing 272 can be seen more clearly.

[0100] A first fan housing 271 may be arranged on the side of the fan 26 opposite to the evaporator 213. The first fan housing 271 has a guide wall 2711 extending around the fan 26 on the side facing the fan 26, and a cooling air inlet 221 is formed on the side of the first fan housing 271 opposite to the fan 26. The cooling air inlet 221 may pass through and extend from the heat-insulating sidewall of the first chamber 241. This first fan housing 271 can efficiently supply cooled air to the storage air inlet 121 and simplifies the manufacturing and assembly process.

[0101] A second fan housing 272 may be arranged on the side of the fan 26 facing the evaporator 213. The second fan housing 272 is formed in a basin shape to define a pressure chamber 2721, within which the fan 26 is at least partially housed. By means of the pressure chamber 2721, the fan 26 can drive air in a desired direction toward the cooling air inlet 221. This helps to improve efficiency. Optionally, the second fan housing 272 may be connected to the first fan housing 271, such that the first fan housing 271 and the second fan housing 272 together enclose the pressure chamber 2721.

[0102] The second fan housing 272 may optionally have an air inlet 2722 that opens toward the evaporator 213.

[0103] The refrigeration module 2 may also include a fan baffle 28. The fan baffle 28 is arranged between the fan 26 and the evaporator 213 to block all straight paths of airflow between the fan 26 and the evaporator 213. The fan baffle 28 effectively prevents water or ice carried by the airflow from the evaporator 213 from approaching the fan 26.

[0104] Optionally, the fan blocker 28 is spaced apart from the second fan housing 272 and located on the side of the second fan housing 272 facing the evaporator 213, and completely blocks the air inlet 2722 in the direction towards the evaporator 213. It should be understood that the fan blocker 28 blocks the air inlet 2722 but does not completely close it. The fan blocker 28 may, for example, be formed integrally with the second fan housing 272.

[0105] The refrigeration module includes a temperature sensor for detecting the temperature within the refrigerated space and a first connection terminal electrically connected to the temperature sensor. The refrigeration module 2 may include a second connection terminal for electrical connection with the first connection terminal. The first connection terminal may include an exposed contact plate, and the second connection terminal may include a resilient contact piece. In the connected state, the resilient contact piece may abut against the contact plate to achieve a conductive connection between the first and second connection terminals.

The feature examples provided in this disclosure are intended to be illustrative and not limiting, unless otherwise stated. In practice, multiple features may be combined with each other as needed and where technically feasible. In particular, features from different embodiments may also be combined with each other.
