[0036] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0037] The following is for reference. Figures 1-3 A vehicle 100 according to an embodiment of the first aspect of the present invention is described.

[0038] like Figures 1-3 As shown, a vehicle 100 according to a first aspect embodiment of the present invention includes: a vehicle refrigerator 10, an air conditioning system 20, and a cleaning air duct 30. The vehicle refrigerator 10 has a refrigerated space 111; the air conditioning system 20 has an airflow duct 21; one end of the cleaning air duct 30 is connected to the airflow duct 21, and the other end of the cleaning air duct 30 is connected to the refrigerated space 111. The vehicle refrigerator 10 has a cleaning mode. In the cleaning mode, the air conditioning system 20 sends gas into the refrigerated space 111 through the airflow duct 21 and the cleaning air duct 30 to clean the refrigerated space 111.

[0039] Specifically, the refrigeration space 111 of the vehicle refrigerator 10 can be used to store items that need to be refrigerated when going out. The air conditioning system 20 is used to provide air conditioning to the vehicle. At the same time, in the refrigerator's cleaning mode, air can also be sent into the refrigeration space 111 through the airflow duct 21 and the cleaning duct 30 to clean the refrigeration space 111.

[0040] When the vehicle refrigerator 10 is in cleaning mode, turn on the air conditioning system 20 so that the air conditioning air enters the refrigerator space 111 through the airflow duct 21 and the cleaning duct 30 to dry the refrigerator space 111. After the air conditioning system 20 has been running for a period of time, turn off the air conditioning system 20 to complete the cleaning of the vehicle refrigerator 10.

[0041] According to the vehicle 100 of the present invention, by setting up a cleaning air duct 30, the gas generated by the air conditioning system 20 can be sent into the refrigeration space 111 to clean the refrigeration space 111. In this way, the original air conditioning system 20 can be used to clean the vehicle refrigerator 10. This not only improves the convenience of cleaning the vehicle refrigerator 10, but also does not require additional processing equipment, reduces the space occupied and production cost of the vehicle refrigerator 10, and thus improves the aesthetics and market competitiveness of the vehicle 100.

[0042] According to some embodiments of the present invention, such as Figures 1-3 As shown, the vehicle 100 also includes: a damper 40 and a first drive member 50. The damper 40 is disposed within the cleaning duct 30 and / or the airflow duct 21. The damper 40 is movable between a first position and a second position. When the damper 40 is in the first position, the airflow duct 21 is connected to the refrigerated space 111 through the cleaning duct 30. When the damper 40 is in the second position, the airflow duct 21 is not connected to the refrigerated space 111. The first drive member 50 is connected to the damper 40 and is used to drive the damper 40 to move between the first position and the second position. That is, the damper 40 can be disposed within the cleaning duct 30, within the airflow duct 21, or both within the airflow duct 21 and the cleaning duct 30. The first drive member 50 provides driving force for the movement of the damper 40 between the first and second positions. When the vehicle refrigerator 10 is in normal use, the damper 40 is in the second position, so that the airflow duct 21 is not connected to the refrigerator space 111, ensuring the normal use of the refrigerator space 111. When the vehicle refrigerator 10 is in cleaning mode, the first drive unit 50 can drive the damper 40 from the second position to the first position, so that the airflow duct enters the refrigerator space 111 from the refrigerator space and dries the refrigerator space 111, effectively reducing the bacteria and odors caused by moisture inside the vehicle refrigerator 10.

[0043] According to some embodiments of the present invention, such as Figures 1-3As shown, the airflow duct 21 includes a first duct section 211 and a second duct section 212 connected along the airflow direction. The second duct section 212 is connected in parallel with the clean air duct 30 at the outlet position of the first duct section 211. The damper 40 is located between the clean air duct 30, the first duct section 211 and the second duct section 212. When the damper 40 is in the first position, it blocks the entrance of the second duct section 212 and the first duct section 211 is connected to the clean air duct 30. When the damper 40 is in the second position, it blocks the entrance of the clean air duct 30 and the first duct section 211 is connected to the second duct section 212. The second air duct section 212 is used to provide air conditioning air to the vehicle interior, and the cleaning air duct 30 is used to connect the first air duct section 211 and the refrigeration space 111. The first air duct section 211 can provide the required airflow to the second air duct section 212 and the refrigeration space 111 respectively by controlling the position of the damper 40. In this way, the position of the damper 40 can be controlled according to the usage requirements, so that the air conditioning system 20 can not only maintain its original functions, but also clean the vehicle refrigerator 10, keeping the inside of the vehicle refrigerator 10 dry and hygienic before use.

[0044] According to some embodiments of the present invention, such as Figures 1-3 As shown, the vehicle refrigerator 10 includes a body 11 and a door 12. The body 11 defines a refrigerated space 111 with an open opening. The door 12 is used to open and close the open opening of the refrigerated space 111. In the cleaning mode, the door 12 is open. The body 11 serves as structural support and a place for storing items. The door 12 can open and seal the open opening of the body 11, thus ensuring the normal operation of the refrigerator. Furthermore, in the cleaning mode, the open door 12 ensures air circulation within the refrigerated space 111, thereby cleaning the vehicle refrigerator 10 and effectively preventing bacteria and odors caused by moisture inside the refrigerator.

[0045] According to some embodiments of the present invention, such as Figures 1-3 As shown, the vehicle refrigerator 10 includes a drawer 13, which is removably disposed within the body 11. One end of the drawer 13 forms a door 12. In cleaning mode, the drawer 13 is pulled outward a preset distance. The interior of the drawer 13 forms a storage space for placing items requiring refrigeration. The front end of the drawer 13 forms a door 12 for opening or closing the body 11, allowing the body 11 to communicate with or be sealed to the outside. In cleaning mode, the drawer 13 being pulled outward a preset distance allows air entering the refrigeration space 111 to be expelled promptly, ensuring air circulation within the refrigeration space 111. This facilitates cleaning of the vehicle refrigerator 10 and effectively prevents bacteria and odors caused by moisture inside the refrigerator 10.

[0046] Specifically, the preset distance can be a preset value set according to the distance between the end of drawer 13 away from door 12 and the rear wall of refrigerator space 111 in the front-back direction when drawer 13 is open. The preset distance is less than or equal to the distance between the connection point of cleaning duct 30 and cabinet 11 and the rear wall of refrigerator space 111 in the front-back direction. This ensures that the air supplied by cleaning duct 30 to refrigerator space 111 can circulate smoothly within refrigerator space 111, thereby improving the purification efficiency and effect of the vehicle refrigerator 10.

[0047] According to some embodiments of the present invention, such as Figures 1-3 As shown, the vehicle refrigerator 10 also includes a second drive member 14, which is disposed on the cabinet 11 and connected to the drawer 13 for driving the drawer 13 to move between an open position and a closed position. When the drawer 13 is in the open position, the opening of the cabinet 11 is open; when the drawer 13 is in the closed position, the opening of the cabinet 11 is closed. The second drive member 14 provides driving force for the movement of the drawer 13, and can drive the drawer 13 to open and close the opening of the cabinet 11.

[0048] According to some embodiments of the present invention, such as Figures 1-3 As shown, the second driving component 14 includes a solenoid valve 141 and a coil spring. The solenoid valve 141 is mounted on the housing 11, and the coil spring connects the solenoid valve 141 and the drawer 13. The solenoid valve 141 drives the drawer 13 to move via the coil spring. Both the solenoid valve 141 and the coil spring have relatively simple structures and are inexpensive. Therefore, using the solenoid valve 141 and the coil spring to control the movement of the drawer 13 can reduce the production difficulty and cost of the vehicle refrigerator 10. When the vehicle refrigerator 10 is in cleaning mode, the solenoid valve 141 drives the drawer 13 to open via the coil spring. After cleaning, the solenoid valve 141 pulls the coil spring back, thereby pulling the drawer 13 back to the closed position, ensuring that the refrigerator housing 11 remains closed and preventing debris from entering the vehicle refrigerator 10.

[0049] According to some embodiments of the present invention, a guide rail is provided inside the housing 11, and the drawer 13 is slidably disposed on the guide rail. The guide rail can be a linear guide rail, which can be used to fix the drawer 13 to the housing 11, and also to limit the sliding direction of the drawer 13, ensuring the normal opening and closing of the drawer 13.

[0050] According to some embodiments of the present invention, such as Figure 1 As shown, the vehicle refrigerator 10 also includes a refrigerator controller 15, which is connected to the air conditioning system 20. The air conditioning system 20 can enter or stop working according to the signal sent by the refrigerator controller 15, thereby realizing the automation of cleaning of the vehicle refrigerator 10.

[0051] In some specific embodiments, such as Figure 1 As shown, the refrigerator controller 15 is electrically connected to the second drive unit 14 and can control the opening and closing of the drawer 13. Furthermore, the refrigerator controller 15 is electrically connected to the first drive unit 50 and can control the movement of the damper 40 in a first position and a second position.

[0052] According to some embodiments of the present invention, such as Figure 1 As shown, the vehicle 100 also includes a vehicle controller 60. The refrigerator controller 15 is connected to the air conditioning system 20 via the vehicle controller 60, which further improves the automation of cleaning the vehicle refrigerator 10. When the vehicle refrigerator 10 needs cleaning, the refrigerator controller 15 sends a signal to the vehicle controller 60, which then controls the air conditioning system 20 to enter the working state, so that the air conditioning system 20 provides gas to the vehicle refrigerator 10 for cleaning.

[0053] like Figure 4 As shown, the cleaning method of the vehicle refrigerator 10 according to the second aspect of the present invention is applied to a vehicle 100 according to the first aspect of the present invention. The vehicle refrigerator 10 includes a cabinet 11 and a door 12. The cabinet 11 defines a refrigerated space 111 with an open opening. The door 12 is used to open and close the open opening of the refrigerated space 111. The cleaning method includes: when the vehicle refrigerator 10 enters a cleaning mode, opening the door 12 and the air conditioning system 20 supplying air to the refrigerated space 111.

[0054] When the vehicle refrigerator 10 enters the cleaning mode, the refrigerator controller 15 controls the solenoid valve 141 to open the door 12, and at the same time controls the first drive unit 50 to drive the air door 40 to move to the second position, so that the first air duct section 211 is connected to the cleaning air duct 30. At the same time, the vehicle controller 60 receives the signal from the refrigerator controller 15 and controls the air conditioning system 20 to enter the working state, so that the air conditioning system 20 delivers gas to the refrigeration space 111, thereby cleaning the vehicle refrigerator 10.

[0055] According to the cleaning method of the vehicle refrigerator 10 of the present invention, the vehicle refrigerator 10 can be self-cleaned by utilizing the existing air conditioning system 20. This not only improves the convenience of cleaning the vehicle refrigerator 10, but also does not require additional processing equipment, reducing the space occupied and production cost of the vehicle refrigerator 100, thereby improving the aesthetics and market competitiveness of the vehicle 100.

[0056] In some specific embodiments of the present invention, the air supplied by the air conditioning system 20 to the refrigeration space 111 is hot air, which can accelerate the drying process of the vehicle refrigerator 10, thereby improving the self-cleaning efficiency of the vehicle refrigerator 10; at the same time, the hot air also has a certain disinfection and sterilization effect, thereby improving the cleaning effect of the vehicle refrigerator 10.

[0057] According to some embodiments of the present invention, the cleaning method further includes: when the vehicle refrigerator 10 meets the preset stopping conditions, controlling the door 12 to close, and the air conditioning system 20 to stop supplying air to the refrigerated space 111.

[0058] The preset stop condition can be a preset value set according to the conditions required for the vehicle refrigerator 10 to reach a dry state. In this way, the vehicle refrigerator 10 can stop the self-cleaning mode after reaching the required state and return the refrigerator to a sealed state, thereby avoiding the continuous operation of the air conditioning system 20 and reducing energy consumption.

[0059] According to some embodiments of the present invention, the preset stop condition includes at least one of the following conditions: the air conditioning system 20 supplies air to the refrigerator compartment 111 for a duration greater than a preset time; the cleanliness of the refrigerator compartment 111 meets a preset cleanliness level; and the humidity of the refrigerator compartment 111 is less than a preset humidity threshold. The preset time can be a preset value set based on the time required for the air conditioning system 20 to supply air to the refrigerator to reach a dry state in the refrigerator compartment 111; the preset cleanliness level can be a preset value set based on the required cleanliness level of the refrigerator; and the preset humidity threshold can be a value set based on the highest humidity value when the refrigerator is in a dry state. By setting the preset stop condition to at least one of the above conditions, while ensuring efficient self-cleaning of the vehicle refrigerator 10, the air conditioning system 20 can be shut off promptly after reaching the desired state, reducing energy consumption.

[0060] For example Figure 4 As shown, the preset stop condition is that the duration of the air supply from the air conditioning system 20 to the refrigerated space 111 is greater than a preset time, where the preset time is t. When the vehicle refrigerator 10 enters the cleaning mode, the refrigerator controller 15 controls the solenoid valve 141 to open the door 12, and simultaneously controls the first drive component 50 to drive the air damper 40 to move to the first position, so that the first air duct section 211 is connected to the cleaning air duct 30. At the same time, the vehicle controller 60 receives the signal from the refrigerator controller 15 and controls the air conditioning system 20 to enter the working state, so that the air conditioning system 20 delivers air to the refrigeration space 111, thereby cleaning the vehicle refrigerator 10. When the duration of the air conditioning system 20 delivering air to the refrigeration space 111 is less than t, the air conditioning system 20 continues to output air. When the duration of the air conditioning system 20 delivering air to the refrigeration space 111 is greater than or equal to t, the vehicle controller 60 turns off the air conditioning system 20 and sends a signal to the refrigerator controller 15, so that the refrigerator controller 15 controls the solenoid valve 141 to pull the coil spring, so that the drawer 13 is in the closed state, and moves the air damper 40 from the first position to the second position, so that the refrigerator body 11 is kept sealed.

[0061] According to some embodiments of the present invention, the cleaning method further includes: confirming that the vehicle refrigerator 10 has reached preset cleaning conditions, and controlling the vehicle refrigerator 10 to enter a cleaning mode. This further improves the automation of cleaning the vehicle refrigerator 10, achieving efficient cleaning of the vehicle refrigerator 10.

[0062] According to some embodiments of the present invention, the preset cleaning conditions include at least one of the following conditions: the self-cleaning function button of the vehicle refrigerator 10 is triggered; the number of consecutive uncleaned uses of the vehicle refrigerator 10 reaches a preset number; the continuous unused time of the vehicle refrigerator 10 reaches a preset number of days threshold.

[0063] Specifically, the number of uses refers to the number of times the vehicle refrigerator 10 is powered on and off. The preset number of uses can be a preset value set based on the number of times the vehicle refrigerator 10 has been powered on and off without being cleaned consecutively. The preset number of days threshold can be a preset value set based on the maximum value of the continuous unused time of the vehicle refrigerator 10. The preset cleaning condition is at least one of the above conditions, that is, the preset cleaning condition can be any one of the above conditions, any combination of the above conditions, or all of the above conditions. Among them, the preset cleaning condition is that when the self-cleaning function button of the vehicle refrigerator 10 is triggered, the user can choose whether to start the self-cleaning system according to actual needs, thereby improving the autonomy of the self-cleaning function of the vehicle refrigerator 10. The preset condition is that when the number of consecutive uncleaned uses of the vehicle refrigerator 10 reaches the preset number of uses, or when the continuous unused time of the vehicle refrigerator 10 reaches the preset number of days threshold, the system can automatically trigger the self-cleaning function, which can further improve the automation of the self-cleaning system of the vehicle refrigerator 10.

[0064] When the refrigerator controller 15 confirms that the vehicle refrigerator 10 has reached the preset cleaning conditions, it controls the vehicle refrigerator 10 to enter the cleaning mode. At this time, the refrigerator controller 15 controls the solenoid valve 141 to open the door 12, and at the same time controls the first drive component 50 to drive the air damper 40 to move to the second position, so that the first air duct section 211 is connected to the cleaning air duct 30. At the same time, the vehicle controller 60 receives the signal from the refrigerator controller 15 and controls the air conditioning system 20 to turn on, so that the air conditioning system 20 delivers air to the refrigerated space 111, thereby cleaning the vehicle refrigerator 10. When the air conditioning system 20 has been running for a period of time and the vehicle refrigerator 10 meets the preset stopping conditions, the vehicle control system turns off the air conditioning system 20 and sends a signal to the refrigerator controller 15, so that the refrigerator controller 15 controls the solenoid valve 141 to pull the coil spring, so that the drawer 13 is in the closed state, and moves the air damper 40 from the second position to the first position, so that the refrigerator body 11 is kept sealed.
