[0033] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0035] In the description of this invention, "several" means one or more, "more than" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0036] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0037] In related technologies, refrigerators are generally fixed in a specific location, and users can only take out the food inside by approaching the refrigerator and opening the door. However, in some cases, it is inconvenient for users to move to the location where the refrigerator is installed.

[0038] Therefore, to meet the needs of these users, a portable refrigerator has been designed in related technologies. This portable refrigerator can move to a user's designated location based on a call signal, allowing the user to easily retrieve the stored food, and then return to its original location to recharge.

[0039] To further enhance the intelligence and convenience of portable refrigerators and improve user experience, some portable refrigerators are equipped with doors that can be automatically opened and closed. For example, after the portable refrigerator is moved to a user's designated location, it controls the door to open, allowing the user to easily retrieve the food stored inside. Then, it controls the door to close, helping to keep the food warm.

[0040] Reference Figures 1 to 3 As shown, it can be understood that a portable refrigerator in one embodiment of the related art includes a cabinet 101, a drive mechanism 201, and a top cover 102. The cabinet 101 has an opening 301 located on its top surface. The top cover 102 is used to open or close the opening 301. In this case, the drive mechanism 201 is a lifting mechanism. Specifically, refer to... Figure 1 As shown, at this time, the drive mechanism 201 drives the top cover 102 to close at the opening 301, sealing the housing 101. (Refer to...) Figure 2 As shown, at this time, the drive mechanism 201 drives the top cover 102 to rise, thereby opening the opening 301, making it convenient for the user to take out the food in the refrigerator.

[0041] Reference Figure 2 and Figure 3As shown, the cabinet 101 includes a storage compartment 202 for storing food items at low temperatures. This storage compartment 202 can be a refrigerator compartment, a freezer compartment, or a variable temperature compartment. Furthermore, an opening 301 connects to the storage compartment 202, meaning the opening 301 is located above the storage compartment 202. Users can store food items in and retrieve them from the storage compartment 202 through the opening 301.

[0042] Reference Figure 2 and Figure 3 As shown, the portable refrigerator also includes a support rod 203 and a tray 204. The upper end of the support rod 203 is fixedly connected to the top cover 102, and the tray 204 is connected to the support rod 203. This allows the support rod 203, tray 204, and top cover 102 to be connected as a single component, meaning they can rise and fall together in the vertical direction. A lifting mechanism drives the support rod 203, tray 204, and top cover 102 to rise and fall together. When the lifting mechanism drives the support rod 203, tray 204, and top cover 102 to rise, the top cover 102 opens the opening 301, allowing the food on the tray 204 to extend beyond the opening 301 without the user needing to reach into the storage compartment 202, making it convenient for the user to access the food. When the lifting mechanism drives the support rod 203, tray 204, and top cover 102 to descend, the food on the tray 204 is retracted into the storage chamber 202, and the top cover 102 closes the opening 301, sealing the food inside the storage chamber 202. The lifting mechanism can be connected to the tray 204, driving the support rod 203 and top cover 102 to rise and fall. The lifting mechanism can also be connected to the support rod 203, driving the tray 204 and top cover 102 to rise and fall. Finally, the lifting mechanism can be connected to the top cover 102, driving the tray 204 and support rod 203 to rise and fall.

[0043] Understandably, the lifting mechanism includes a column 205 and a pulley system. The support rod 203 has a guide hole 302 through which the column 205 passes. The pulley system connects the column 205 and the support rod 203, driving the support rod 203 to rise and fall along the column 205. Since the top cover 102 and the tray 204 are fixed to the support rod 203, which is sleeved on the column 205, the motor drives the pulley system to move the support rod 203 up and down along the column 205, thereby causing the top cover 102 and the tray 204 to rise and fall together, realizing the opening and closing actions of the door.

[0044] Understandably, the pulley system includes a movable pulley, a fixed pulley, and a rope. The movable pulley is installed in the guide hole 302 of the support rod 203, and the fixed pulley is installed on the column 205. The fixed pulley is higher than the movable pulley. The rope is wound around the movable pulley and the fixed pulley. The motor raises or lowers the movable pulley relative to the fixed pulley by winding the rope, thereby raising or lowering the support rod 203 relative to the column 205.

[0045] It should be noted that in some other embodiments, the lifting mechanism may also be a linear slide module or an electric actuator, as long as it can drive the support rod 203 to slide on the column 205, and is not limited here.

[0046] Reference Figure 2 and Figure 3 As shown, the housing 101 includes a compressor compartment 206 located below the storage compartment 202. The lifting mechanism includes a motor and a transmission mechanism, with the motor located in the compressor compartment 206. The bottom wall of the storage compartment 202 has a through-hole 303 connecting the storage compartment 202 and the compressor compartment 206. The transmission mechanism can pass through the through-hole 303 and connect to one of the tray 204, support rod 203, or top cover 102, thereby transmitting power from the motor to the tray 204, support rod 203, or top cover 102. A compressor and condenser can also be housed in the compressor compartment 206. By arranging the condenser, compressor, motor, and at least part of the transmission mechanism within the compressor compartment 206, the space utilization of the storage compartment 202 can be improved.

[0047] Reference Figure 3 As shown, the bottom end of the support rod 203 is provided with a base 304 for supporting the tray 204. The top surface of the base 304 supports the bottom surface of the tray 204, thereby improving the connection strength of the tray 204 and making it less prone to loosening and bending. At least a portion of the base 304 can enter the through hole 303, thereby moving at least a portion of the base 304 outside the storage compartment 202, preventing the base 304 from occupying too much storage space and increasing the space utilization rate in the storage compartment 202.

[0048] Understandably, the portable refrigerator includes a walking mechanism that drives the cabinet 101 to move, enabling the portable refrigerator to move. The portable refrigerator can be moved to the vicinity of the user, and then the lifting mechanism can raise the tray 204 to facilitate the user's storage and retrieval of items on the tray 204. This eliminates the need for the user to go to a fixed location to store or retrieve items, improving the flexibility of the portable refrigerator and solving the pain point of users not wanting to walk to the refrigerator to retrieve items.

[0049] It is understood that the walking mechanism includes rollers located at the bottom of the cabinet 101, which are driven to rotate via a power output structure, thereby propelling the refrigerator forward or backward. For example, refer to... Figure 2 and Figure 3 As shown, the walking mechanism includes two walking wheels 207 and one auxiliary wheel 208. The two walking wheels 207 are respectively arranged on the left and right sides of the refrigerator chassis. The power output structure is connected to the two walking wheels 207 respectively. The auxiliary wheel 208 is arranged on the front side of the chassis.

[0050] Reference Figure 3 As shown, it can be understood that during the opening and closing of the mobile refrigerator, the cold air inside the refrigerator and the hot air outside exchange heat at the opening 301 to produce condensation water. The cold air inside the storage compartment 202 and the hot air inside the compressor chamber 206 exchange heat at the through hole 303 to produce condensation water. Water droplets adhere to the inner wall of the storage compartment 202.

[0051] Reference Figure 4 As shown, it can be understood that in one embodiment of the present invention, the bottom wall of the storage compartment 202 is provided with a water collection tray 401, and the water collection tray 401 is provided with a drain hole 402. When condensate accumulates, the water flows down along the inner wall of the storage compartment 202 and collects in the water collection tray 401, and is discharged into the compressor chamber 206 through the drain hole 402, thereby reducing the water accumulation in the storage compartment 202, improving the user experience, and reducing the impact of water accumulation on the preservation effect.

[0052] Reference Figure 4 As shown, the water collection tray 401 is equipped with a water collection trough 403, and the drain hole 402 is located at the bottom of the water collection trough 403. The water collection trough 403 is a recessed portion provided on the side of the water collection tray 401 facing the storage compartment 202, which allows condensate to flow into the water collection trough 403 and then be discharged into the compressor compartment 206 through the drain hole 402. It can be understood that the side wall of the water collection trough 403 can be provided with an inclined guide surface, which makes it easier to guide the condensate to flow into the water collection trough 403. The drain hole 402 is located at the bottom of the water collection trough 403; in other words, the drain hole 402 is located at the lowest point of the upper surface of the water collection tray 401, which makes it easier for condensate to drain through the drain hole 402 and reduces water accumulation.

[0053] It is understandable that a sealing ring is provided between the base 304 and the inner wall of the through hole 303. When the base 304 enters the through hole 303, the sealing ring seals the gap between the base 304 and the inner wall of the through hole 303. This can reduce the heat exchange between the cold air inside the storage compartment 202 and the hot air inside the compressor compartment 206, reduce the formation of condensate, and prevent condensate from flowing down from the gap between the base 304 and the inner wall of the through hole 303 and damaging the components inside the compressor compartment 206.

[0054] Reference Figure 4As shown, the portable refrigerator includes a connecting pipe 404, one end of which is connected to a drain hole 402, and the other end is located inside the compressor compartment 206. The connecting pipe 404 serves to guide condensate, allowing it to drain to a predetermined location within the compressor compartment 206, thus reducing the risk of condensate splashing.

[0055] Reference Figure 4 As shown, it can be understood that the water collection tray 401 is installed on the bottom wall of the storage compartment 202, which facilitates the collection of condensate. The water collection tray 401 is provided with a connector 405, which is columnar and extends downward and penetrates the bottom wall of the storage compartment 202. The drain hole 402 is located at the corresponding position of the connector 405 and penetrates the connector 405. The connector 405 is connected to the connecting pipe 404, so that the condensate directly enters the connecting pipe 404 along the drain hole 402 in the connector 405, and does not enter between the water collection tray 401 and the bottom wall of the storage compartment 202, thereby reducing the leakage of condensate.

[0056] Reference Figure 5 As shown, it can be understood that in another embodiment of the present invention, the water collection tray 401 and the bottom wall of the storage chamber 202 are an integral structure, that is, a drain hole 402 is directly opened on the bottom wall of the storage chamber 202, and the drain hole 402 penetrates the bottom wall of the storage chamber 202, thereby connecting the storage chamber 202 and the compressor chamber 206.

[0057] Reference Figure 6 As shown, in another embodiment of the present invention, the water collection tray 401 is a separate structure and is connected to the bottom wall of the storage compartment 202. The water collection tray 401 can be fixed by screws to the bottom wall of the storage compartment 202. The connection of the water collection tray 401 to the bottom wall of the storage compartment 202 directly exposes the connection position of the drain hole 402, making it easier to install and remove the connecting pipe 404. The water collection tray 401 is provided with a clearance hole, allowing the transmission mechanism to pass through the clearance hole into the through hole 303. The diameter of the through hole 303 is larger than the diameter of the clearance hole, and the position of the drain hole 402 corresponds to the inner wall of the through hole 303, that is, the drain hole 402 is located below the lower edge of the inner wall of the through hole 303. After the lifting mechanism opens the top cover 102, the bottom support 304 rises simultaneously, thus disengaging from the through hole 303. Condensate flows from the bottom wall of the storage chamber 202 to the through hole 303 and flows down along the inner wall of the through hole 303. Then it falls into the water collection trough 403 of the water collection tray 401 and finally flows out from the drain hole 402.

[0058] Reference Figure 7 and Figure 8As shown, the portable refrigerator also includes a water collection box 801, located inside the compressor compartment 206, for collecting liquid discharged from the drain hole 402. The water collection box 801 can be located below the drain hole 402, collecting condensate without the need for the connecting pipe 404. Alternatively, the water collection box 801 can be located in other positions, connected to the drain hole 402 via the connecting pipe 404, with one end of the connecting pipe 404 connected to the drain hole 402 and the other end located inside the water collection box 801. The connecting pipe 404 can be a corrugated pipe, which can extend and retract its length to better adapt to the changing positions of the water collection box 801 and drain hole 402 in different models of portable refrigerators. Because the compressor and condenser, among other heat-generating components, are located inside the compressor compartment 206, the compartment maintains a high temperature. This high temperature allows for the evaporation of condensate, achieving not only drainage but also facilitating heat dissipation for the compressor and condenser.

[0059] It should be noted that in some other embodiments, the water collection box 801 may not be provided. Instead, a drain pipe is connected to the drain hole 402, and the outlet of the drain pipe is located outside the cabinet 101, so that the condensate can be directly discharged from the mobile refrigerator.

[0060] Reference Figure 7 and Figure 8 As shown, it can be understood that the bottom of the water collection box 801 is provided with a positioning protrusion 802, and the end of the connecting pipe 404 is sleeved on the positioning protrusion 802. The positioning protrusion 802 is used to position the water outlet end of the connecting pipe 404, thereby fixing both ends of the connecting pipe 404 and preventing the connecting pipe 404 from swaying during the movement of the refrigerator, which would cause condensate to be thrown out of the water collection box 801.

[0061] Reference Figure 7 and Figure 8 As shown, the portable refrigerator includes refrigerant pipes 803, which connect to the compressor's exhaust port. A portion of the refrigerant pipes 803 is located within the water collection box 801. The high-temperature, high-pressure refrigerant flowing from the compressor heats the condensate in the water collection box 801, accelerating its evaporation into the air. The refrigerant pipes 803 coil at the bottom of the water collection box 801, forming multiple ring-shaped structures, increase the heat exchange area between the refrigerant pipes 803 and the condensate, thus improving evaporation efficiency.

[0062] It should be noted that in some other embodiments, the refrigerant pipe 803 may also be wrapped around the outer periphery of the water collection box 801, so that the refrigerant pipe 803 can heat the liquid in the water collection box 801.

[0063] It should be noted that the door structure of the refrigerator in this embodiment of the invention can also be other than... Figures 1 to 3 The structure other than the top cover 102 shown.

[0064] In some other embodiments, the opening 301 may be located on the side of the housing 101, with one side of the door hinged to the housing 101, and the drive mechanism 201 driving the door to open or close the opening 301 in the horizontal direction.

[0065] In some other embodiments, the opening 301 may be located on the side of the housing 101, the upper end of the door is hinged to the housing 101, and the drive mechanism 201 drives the door to open or close the opening 301 in the vertical direction.

[0066] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
