[0039] The present application provides a refrigerator, which is a refrigeration device for keeping constant low temperature and a civil product for keeping food or other articles in constant low temperature state. Generally, the refrigerator has a compressor, an ice maker, a cabinet or a box for ice making and a storage box with refrigeration device. The volume of the household refrigerator is generally 20-500 liters. There are many kinds of refrigerators, which are generally classified according to the cooling inside, the use, the climate environment, the shape, the placement and the refrigeration mode. The high-end household refrigerators on the market also have the functions of odor removal, sterilization and food preservation.

[0040] Please refer to Figures 1 to 5 In an embodiment of the present application, the refrigerator 10 comprises a refrigerator main machine 100, a refrigerator sub-machine 200 and a moving chassis 300. The refrigerator main machine 100 is formed with a containing cavity 110. The refrigerator sub-machine 200 is movably arranged in the containing cavity 110. The refrigerator sub-machine 200 has a first position in which the refrigerator sub-machine 200 is accommodated in the containing cavity 110, and a second position in which the refrigerator sub-machine 200 is moved outside the containing cavity 110. The moving chassis 300 is used to support the refrigerator sub-machine 200 and move the refrigerator sub-machine 200 when the refrigerator sub-machine 200 is in the second position.

[0041] Specifically, the refrigerator main machine 100 is fixedly placed on the ground. The containing cavity 110 is located at the lower part of the refrigerator main machine 100. Generally, the refrigerator sub-machine 200 is located in the containing cavity 110. When the user needs to take the articles in the refrigerator sub-machine 200, the refrigerator sub-machine 200 is moved from the first position in the containing cavity 110 to the second position. When the refrigerator sub-machine 200 is in the second position, the moving chassis 300 can support the refrigerator sub-machine 200 and move the refrigerator sub-machine 200 to the position of the user or to the position designated by the user, and then the user takes the articles in the refrigerator sub-machine 200. The number of the refrigerator sub-machines 200 can be one, two or more, which is not specifically limited.

[0042] Before the refrigerator 10 is used, the moving path of the moving chassis 300 can be preset, and a plurality of stopping points can be set on the preset moving path. When the moving chassis 300 is received by the refrigerator sub-machine 200, the moving chassis 300 can move according to the preset moving path and then reach the specified stopping point. For example, when the use scenario of the refrigerator 10 is at home, the movable area of the moving chassis 300 can be preset into the moving path. A stopping point can be set in each of the bedroom, bathroom, living room, dining room, etc. A two-dimensional code positioning sticker with the location information of the place can be set at the stopping point. When the user needs to take the items in the refrigerator sub-machine 200, the user can scan the positioning sticker by the mobile phone, so that the moving chassis 300 moves the refrigerator sub-machine 200 to the specified location, and the user can take the items in the refrigerator sub-machine 200. When the use scenario of the refrigerator 10 is in an office building or other office scenarios, the movable area of the moving chassis 300 can be preset into the moving path. A stopping point can be set at each workstation, and a two-dimensional code positioning sticker with the location information of the place can be set at each workstation. When the user needs to take the items in the refrigerator sub-machine 200, the user can scan the positioning sticker by the mobile phone, so that the moving chassis 300 moves the refrigerator sub-machine 200 to the specified location, and the user can take the items in the refrigerator sub-machine 200. Of course, the user can also directly operate the mobile phone software to make the moving chassis 300 move the refrigerator sub-machine 200 to the specified location, and the user can take the items in the refrigerator sub-machine 200, without having to scan the positioning sticker by the mobile phone. The application scenarios of the refrigerator 10 are various, and are not specifically limited herein.

[0043] The moving path information of the moving chassis 300 can be drawn by the staff or drawn by the user according to the user's own preferences. The moving path is exclusive to the user, and the specific limitation is not made. The obstacle avoidance radar 320 can be arranged in the moving chassis 300. The obstacle avoidance radar 320 can detect whether there is an obstacle on the moving path when the moving chassis 300 moves along the moving path, so as to avoid the moving chassis 300 carrying the refrigerator sub-machine 200 colliding with the obstacle. The obstacle avoidance radar 320 can detect whether there is an obstacle on the moving path by reflecting sound waves, scattering laser beams, or other methods, and the specific limitation is not made.

[0044] Further, an automatic navigation system and a positioning module can also be arranged in the moving chassis 300, so that the user does not need to preset the moving path information of the moving chassis 300 before using the refrigerator 10. The moving chassis 300 can scan the obstacle in real time and plan the moving path by itself to move the refrigerator sub-machine 200 to the position specified by the user.

[0045] The refrigerator main machine 100 can also be provided with a scanning system. When a user approaches the refrigerator 10, or when the user is close to the refrigerator 10, the refrigerator 10 receives an instruction to move out of the refrigerator sub-machine 200 and does not perform a moving operation, so as to avoid collision between the refrigerator sub-machine 200 and the user during movement of the refrigerator sub-machine 200 from the first position to the second position.

[0046] The technical scheme of the present application provides a containing cavity 110 in the refrigerator main machine 100, and a refrigerator sub-machine 200 movably installed in the containing cavity 110. The refrigerator sub-machine 200 has a first position in the containing cavity 110 and a second position outside the containing cavity 110. When a user needs to take out an item in the refrigerator sub-machine 200, the refrigerator sub-machine 200 is moved from the first position to the second position. Then, the moving base plate 300 can receive the refrigerator sub-machine 200 and drive the refrigerator sub-machine 200 to move to a position where the user is located or a position specified by the user, so that the user can take out the item in the refrigerator sub-machine 200. The technical scheme of the present application improves the convenience of using the refrigerator 10, meets the personalized needs of young people for using the refrigerator 10, and meets the development trend of the new era of human-computer interaction and Internet of Things. The technical scheme of the present application also provides great convenience for the life of the elderly.

[0047] In an embodiment, the containing cavity 110 is provided with a first air door, and the refrigerator sub-machine 200 is provided with a second air door. When the refrigerator sub-machine 200 is in the first position, the first air door and the second air door are connected and conducted. Specifically, the refrigerator 10 uses air cooling for refrigeration, and the refrigerator main machine 100 and the refrigerator sub-machine 200 use the same set of refrigeration systems, which is low in cost and can save energy consumption. When the refrigerator sub-machine 200 is in the first position, the first air door and the second air door are connected and conducted. At this time, the refrigerator sub-machine 200 is connected to the refrigeration system of the refrigerator main machine 100, and shares a set of refrigeration systems with the refrigerator main machine 100.

[0048] In an embodiment, the first air door is provided with a first switch valve, and the second air door is provided with a second switch valve. When the refrigerator sub-machine 200 is in the first position, the first switch valve and the second switch valve are opened to connect and conduct the first air door and the second air door. When the first air door and the second air door are disconnected, the first switch valve and the second switch valve are closed.

[0049] Specifically, to avoid the problem that the first damper continues to cool the containing cavity 110 after the refrigerator 200 is removed from the containing cavity 110, and the cooling capacity of the refrigerator 200 is lost through the second damper after the refrigerator 200 is removed, a first switch valve is arranged at the first damper to open or close the first damper, and a second switch valve is arranged at the second damper to open or close the second damper, so that when the first damper and the second damper are disconnected, the first switch valve closes the first damper and the second switch valve closes the second damper to prevent the above-mentioned problem from occurring. At the same time, when the refrigerator 200 is in the first position or the refrigerator 200 is moved from the second position to the first position, the first switch valve and the second switch valve are both opened to make the first damper and the second damper conductive, and the refrigerator 200 is connected to the refrigeration system of the refrigerator mother machine 100.

[0050] Referring to Figure 2 and Figure 3 In an embodiment, the containing cavity 110 has a cavity opening 111, and the refrigerator 10 further comprises a mounting rack 400 movably arranged in the containing cavity 110 and extending towards the cavity opening 111, and the refrigerator 200 is mounted on the mounting rack 400.

[0051] Specifically, the refrigerator 200 is hung on the mounting rack 400, when it is needed to move the refrigerator 200 from the first position to the second position, the mounting rack 400 drives the refrigerator 200 to move out of the containing cavity 110 from the cavity opening 111 of the containing cavity 110 to the second position, and the moving base plate 300 moves to the lower side of the refrigerator 200, the moving base plate 300 supports the refrigerator 200 and moves the refrigerator 200 to a designated position. The material of the mounting rack 400 is a hard material, and the type of the hard material can be ABS, HIPS, PP, PC, etc., or metal or alloy material, etc., as long as it can bear the weight of the refrigerator 200, and no specific limitation is made herein.

[0052] Referring to Figures 1 to 5In an embodiment, the refrigerator 10 further comprises a door body 500 connected to the mounting frame 400 at an end close to the cavity opening 111, and the door body 500 is used to open or cover the cavity opening 111. Specifically, the door body 500 is connected to the mounting frame 400 at an end close to the cavity opening 111, and when the mounting frame 400 drives the refrigerator machine 200 to move from the first position to the second position, the door body 500 moves together with the mounting frame 400, and after the moving chassis 300 receives the refrigerator machine 200 to move away, the door body 500 is retracted together with the mounting frame 400, and covers the accommodation cavity 110. By setting a separate door body 500 to cover the accommodation cavity 110, it can avoid foreign matter or other sundries falling into the accommodation cavity 110 of the refrigerator mother machine 100 during use, and keep the accommodation cavity 110 clean.

[0053] Please refer to Figure 2 In an embodiment, the number of refrigerator machines 200 is at least two, and the two refrigerator machines 200 are arranged in the accommodation cavity 110 and are separated from each other. Specifically, the number of refrigerator machines 200 can be set to two, and the two refrigerator machines 200 are respectively used to place articles, and when a user needs to take articles, only one of the two refrigerator machines 200 needs to be moved to the user or a specified location of the user by the moving chassis 300. When the user needs to take articles in the refrigerator machine 200, any one of the two refrigerator machines 200 can be specified to move, so that the user can take the articles he needs. In the accommodation cavity 110, a partition can also be made to separate the two refrigerator machines 200 from each other, and each refrigerator machine 200 operates independently without affecting the operation of the other refrigerator machine 200. At the same time, by arranging two refrigerator machines 200 in the accommodation cavity 110 of a fixed size, the volume of the refrigerator machine 200 can be further reduced, thereby reducing the overall weight of the refrigerator machine 200, so that the mounting frame 400 can stably carry the refrigerator machine 200, and the moving chassis 300 also facilitates carrying the refrigerator machine 200 to move.

[0054] Please refer to Figure 2 、 Figure 3 and Figure 5 In an embodiment, the cavity opening 111 is located at the front side of the refrigerator mother machine 100, the bottom of the refrigerator mother machine 100 is provided with a groove 120, the groove 120 has a first opening 121 facing downward and a second opening 122 facing forward, and the moving chassis 300 is arranged in the groove 120 and can be moved out of the bottom of the refrigerator mother machine 100 through the second opening 122.

[0055] Specifically, the first opening 121 is arranged downwardly and directly towards the ground. The moving chassis 300 is installed in the groove 120 at the bottom of the refrigerator main machine 100 and is in contact with the ground. The groove 120 can limit the position of the moving chassis 300 and prevent the position of the moving chassis 300 from deviating at the bottom of the refrigerator main machine 100, so that the moving chassis 300 cannot move to the designated location after being moved out of the bottom of the refrigerator main machine 100. The cavity opening 111 of the accommodating cavity 110 is located at the front side of the refrigerator main machine 100, and the second opening 122 is also open forwardly. When the refrigerator sub-machine 200 is moved from the first position to the second position, the moving chassis 300 is opened out of the second opening 122 and is moved to the lower side of the refrigerator sub-machine 200 to receive and move the refrigerator sub-machine 200.

[0056] In an embodiment, the groove bottom of the groove 120 is provided with a charging module. The refrigerator main machine 100 can charge the moving chassis 300 through the charging module. Specifically, the charging mode of the moving chassis 300 can be set as a wireless charging mode. The charging module can be arranged at any position in the groove 120 so that the moving chassis 300 can be attached to the charging module to charge the moving chassis 300. Further, the length of the groove 120 can be longer than the length of the moving chassis 300. The charging module is arranged at the side of the groove 120 away from the second opening 122. When the moving chassis 300 does not need to be charged, the moving chassis 300 does not contact the charging module. When the moving chassis 300 needs to be charged, the moving chassis 300 moves to the position where the charging module is arranged and contacts the charging module to start charging.

[0057] Please refer to Figure 4 In an embodiment, the moving chassis 300 comprises a jacking mechanism 310. The jacking mechanism 310 is provided with a placing groove 311 for receiving the refrigerator sub-machine 200. Specifically, when the moving chassis 300 moves to the lower side of the refrigerator sub-machine 200, the refrigerator sub-machine 200 needs to be jacked up by the jacking mechanism 310 so that the refrigerator sub-machine 200 is separated from the mounting frame 400, and then the moving chassis 300 is moved transversely outwards. The jacking mechanism 310 is retracted, and then the moving chassis 300 moves the refrigerator sub-machine 200 to the designated location. The placing groove 311 of the jacking mechanism 310 is used to receive the refrigerator sub-machine 200 and also plays a role of limiting and fixing the refrigerator sub-machine 200. When the moving chassis 300 suddenly stops moving, the refrigerator sub-machine 200 does not slide to the direction of the moving of the moving chassis 300 due to inertia.

[0058] Please refer to Figure 2 and Figure 3In an embodiment, the refrigerator main machine 100 further comprises a sliding rail 130 and a sliding block 140 which are in sliding cooperation with each other, one of the sliding rail 130 and the sliding block 140 is installed on the accommodating cavity 110, and the other is installed on the mounting frame 400.

[0059] Specifically, in the embodiment, the sliding rail 130 is installed in the accommodating cavity 110, and the sliding block 140 is installed on the mounting frame 400, so that the mounting frame 400 can drive the refrigerator sub-machine 200 to move from the first position to the second position. The type of the sliding rail 130 can be a roller type sliding rail 130, a steel ball type sliding rail 130, or other types of sliding rails 130, which are not limited here. The number of the sliding block 140 and the sliding rail 130 is two sets, two sliding rails 130 are respectively installed on opposite sides of the accommodating cavity 110, and two sliding blocks 140 are in sliding cooperation with the two sliding rails 130. The mounting frame 400 can be provided as two load-bearing rods, one end of the two load-bearing rods is fixedly connected with one sliding block 140, and the other end is fixedly connected with the other sliding block 140, the two load-bearing rods and the two sliding blocks 140 form a mounting position for the refrigerator sub-machine 200, the refrigerator sub-machine 200 is installed on the mounting position and hung on the mounting frame 400.

[0060] In an embodiment, the refrigerator main machine 100 further comprises a driving device, which is arranged in the accommodating cavity 110, and is connected with the sliding rail 130 and the sliding block 140.

[0061] Specifically, when the user needs to take the items in the refrigerator sub-machine 200, after the refrigerator 10 receives the relevant instructions, the mounting frame 400 can automatically drive the refrigerator sub-machine 200 to slide from the first position to the second position, and then move the chassis 300 to the lower side of the refrigerator sub-machine 200, receive the refrigerator sub-machine 200 and move to the designated position. The driving device is connected with the sliding rail 130 and the sliding block 140, the sliding rail 130 is fixedly installed on the accommodating cavity 110, the driving device can drive the sliding block 140 to move relative to the sliding rail 130, so that the mounting frame 400 connected with the sliding block 140 can be moved, thereby driving the refrigerator sub-machine 200 to move from the first position to the second position.

[0062] The application also provides a control method of the refrigerator 10, the specific structure of which is referred to the above embodiments. Since the refrigerator 10 adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Please refer to Figure 6 In an embodiment, the control method of the refrigerator 10 comprises the following steps:

[0063] S10, acquire the moving instruction of the refrigerator 10, control the refrigerator 10 to move from the first position to the second position;

[0064] Specifically, the user can send a moving instruction to the refrigerator 10 through a mobile phone or other mobile terminal to take out the goods in the refrigerator 10. After receiving the moving instruction, the refrigerator 10 controls the driving motor to work, and the driving motor drives the sliding block 140 to slide, so that the mounting frame 400 drives the refrigerator 10 to move from the first position to the second position.

[0065] S20, when the signal that the refrigerator 10 moves to the second position is acquired, control the moving chassis 300 to move to the lower side of the refrigerator 10;

[0066] Specifically, when the refrigerator 10 acquires the signal that the refrigerator 10 moves to the second position, the signal is transmitted to the moving chassis 300, and the moving chassis 300 moves out of the second opening 122 at the bottom of the refrigerator 10, and then moves to the lower side of the refrigerator 10 to receive the refrigerator 10.

[0067] S30, control the moving chassis 300 to drive the refrigerator 10 to move to a designated position.

[0068] Specifically, after receiving the refrigerator 10, the moving chassis 300 can move according to the preset moving path and move the refrigerator 10 to the position of the user or to the position designated by the user. The moving path information of the moving chassis 300 can be drawn by the staff, or can be drawn by the user according to his own preference. The moving path is not limited. The obstacle avoidance radar 320 can be arranged in the moving chassis 300. The obstacle avoidance radar 320 can detect whether there is an obstacle on the moving path when the moving chassis 300 moves along the moving path, so as to avoid the moving chassis 300 carrying the refrigerator 10 colliding with the obstacle. The obstacle avoidance radar 320 can detect whether there is an obstacle on the moving path by reflecting sound waves, or can detect whether there is an obstacle on the moving path by scattering laser, or can detect whether there is an obstacle on the moving path by other ways, which is not limited here.
