[0030] Embodiments of the present invention are described in detail below, examples of which are illustrated 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 intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] It should be noted that the mobile air conditioner with the energy storage device is currently inseparable from the energy storage device, resulting in the defects of large volume and heavy quality of the mobile air conditioner, which is not conducive to portable use. For individual batteries separated from the air conditioner body, a special mechanical switch needs to be actuated during use to manually switch between power supply of the mains or the energy storage device to prevent double power supply conflict and ensure equipment safety, which reduces user experience. In addition, when connecting the mobile air conditioner and the energy storage device, power supply is usually connected through a cable, which affects the appearance of the mobile air conditioner. Based on this, the application provides a portable air conditioner and a power supply system thereof. Through the power supply system, double power supply to the mobile air conditioner at the same time can be prevented, the situation of external power supply and the energy storage device supplying power to the mobile air conditioner at the same time is avoided, the safety of the mobile air conditioner is ensured, manual operation is not required, user experience is improved, and the system also does not require a special switch and manual wiring, realizing wireless connection of the mobile air conditioner and the energy storage device.

[0032] The portable air conditioner and the power supply system thereof according to the embodiments of the application are described below with reference to the accompanying drawings.

[0033] Figure 1 FIG. 1 is a structural schematic diagram of a power supply system of a portable air conditioner according to an embodiment of the application. As shown in FIG. 1, the portable air conditioner includes an air conditioner body 100, and the power supply system 200 includes a first power supply interface 210 and a second power supply interface 230. Figure 1

[0034] Among them, the first power supply interface 210 and the second power supply interface 230 are both arranged on the air conditioner body 100, and the first power supply interface 210 is used to connect an external power supply 220 to form a first power supply path, and the second power supply interface 230 is used to connect an energy storage device 240 to form a second power supply path. Among them, the first power supply path and the second power supply path are selectively conducted to supply power to the portable air conditioner.

[0035] That is, in the power supply system of the portable air conditioner, two power supply paths are included, which are a first power supply path for supplying power to the air conditioner body 100 through the external power supply 220 via the first power supply interface 210, and a second power supply path for supplying power to the air conditioner body 100 through the energy storage device 240 via the second power supply interface 230. During power supply, only one power supply path is in a conducting state and the other power supply path is in a disconnected state at the same time, and the air conditioner body 100 is supplied with power through the conducting power supply circuit.

[0036] For example, as shown in FIG. 2, the first power supply interface 210 and the second power supply interface 230 are arranged on the air conditioner body 100, and the first power supply interface 210 is used to connect the external power supply 220 to form the first power supply path, and the second power supply interface 230 is used to connect the energy storage device 240 to form the second power supply path. Figure 2 ​As shown, when the external power supply 220 supplies power to the air conditioner body 100, the first power supply path is conducted. If the energy storage device 240 is connected to the second power supply interface 230 at this time, the external power supply 220 will immediately stop supplying power to the air conditioner body 100, ensuring that only one power supply can supply power to the air conditioner body 100, that is, only the energy storage device 240 supplies power to the air conditioner body 100, and when the connection between the energy storage device 240 and the second power supply interface 230 is disconnected again, the external power supply 220 will immediately resume supplying power to the air conditioner body 100. The external power supply 220 can be a city power supply or a power supply converted from a city power supply. Figure 3 As shown, when the energy stored in the energy storage device 240 supplies power to the air conditioner body 100, the second power supply path is conducted, so that the portable air conditioner can be used when it is far away from the external power supply 220 or during movement. If the external power supply 220 is connected to the first power supply interface 210 at this time, the energy storage device 240 will immediately stop supplying power to the air conditioner body 100, ensuring that only one power supply can supply power to the air conditioner body 100, that is, only the external power supply 220 supplies power to the air conditioner body 100, and when the connection between the external power supply 220 and the first power supply interface 210 is disconnected again, the energy storage device 240 will immediately resume supplying power to the air conditioner body 100. Thus, it can be ensured that only one of the first power supply path formed by the first power supply interface 210 and the external power supply 220 and the second power supply path formed by the second power supply interface 230 and the energy storage device 240 supplies power to the air conditioner body 100 during operation, and when one of the power supply paths stops working, the other power supply path can immediately resume supplying power to the air conditioner body 100, that is, when the first power supply interface 210 supplies power, the second power supply interface 230 stops supplying power, or when the second power supply interface 230 supplies power, the first power supply interface 210 stops supplying power.

[0037] According to the energy storage system of the embodiment of the present application, the external power supply is connected to the first power supply interface provided on the air conditioner body to form the first power supply path, and the energy storage device is connected to the second power supply interface provided on the air conditioner body to form the second power supply path, and the portable air conditioner is powered according to the mode that the first power supply path and the second power supply path are conducted alternately, which can effectively avoid the situation that the external power supply and the energy storage device supply power to the portable air conditioner at the same time, ensures the safety of power consumption of the portable air conditioner, and does not need manual intervention or a special switch, thereby improving the user experience.

[0038] In some embodiments, as shown in Figure 4As shown, the power supply output interface 241 is arranged above the energy storage device 240, and is used in cooperation with the second power supply interface 230 below the air conditioner body 100. When the power supply output interface 241 is inserted into the second power supply interface 230, the energy storage device 240 can also block the first power supply interface 210, preventing the external power supply 220 from supplying power to the portable air conditioner, thereby disabling the first power supply path.

[0039] Optionally, the second power supply interface 230 is a female head or a male head, the power supply output interface 241 on the energy storage device 240 is a male head or a female head, and the energy storage device 240 is further configured with a blocking member 242. The blocking member 242 is used to block the first power supply interface 210 when the male head is inserted into the female head.

[0040] Specifically, when the energy storage device 240 is used to supply power to the air conditioner body 100, that is, the power supply output interface 241 (assuming a male head) of the energy storage device 240 is inserted into the power supply interface 230 (assuming a female head) of the air conditioner body 100, the blocking member 242 is arranged to block the first power supply interface 210, preventing the external power supply 220 from supplying power to the air conditioner body 100 through the first power supply interface 210. The blocking member 242 can be a blocking piece, and thus, the physical blocking method can be used to avoid the misconnection of the external power supply, that is, the power supply interface is disconnected by the simplest blocking method, thereby effectively reducing the risk of dual power supply.

[0041] It should be noted that the power supply output interface 241 is inserted into the second power supply interface 230 to supply power to the portable air conditioner, which can directly connect the air conditioner body 100 and the energy storage device 240, without the need for external cables. This method not only makes the appearance of the portable air conditioner more beautiful, but also realizes the modular installation of the energy storage device, which is simple and convenient.

[0042] In some embodiments, with reference to Figure 5 As shown, the energy storage device 240 is further configured with a third power supply interface 243, which is used to connect the external power supply 220, so as to charge the energy storage device 240 and / or supply power to the portable air conditioner.

[0043] Further, with reference to Figure 5As shown, the energy storage device 240 further comprises a battery pack 244 and a charging control panel 245, the output end of the third power supply interface 243 is connected to the input end of the charging control panel 245, the battery pack 244 and the power output interface 241 are connected, and the battery pack 244 and the power output interface 241 are connected to the output end of the charging control panel 245 through a node, when the energy storage device 240 is connected to the external power supply 220 through the third power supply interface 243 and the power output interface 241 is connected to the second power supply interface 230, the charging control panel 245 controls the external power supply 220 to charge the battery pack 244 and / or to supply power to the portable air conditioner.

[0044] Specifically, when the external power supply 220 is connected to the energy storage device 240, if the power output interface 241 of the energy storage device 240 is disconnected from the second power supply interface 230, that is, when the energy storage device 240 is only connected to the external power supply 220, the energy storage device 240 can be connected to the external power supply 220 through the third power supply interface 243 to directly charge the battery pack 244.

[0045] When the power output interface 241 of the energy storage device 240 is connected to the second power supply interface 230, that is, when the energy storage device 240 is connected to the external power supply 220 and the air conditioner body 100 of the portable air conditioner at the same time, as shown in Figure 6 As shown, it is necessary to control the charging of the energy storage device 240 and the power supply of the portable air conditioner through the charging control panel 245, for example, the charging control panel 245 can be provided with a virtual button for charging only the battery pack 244 in the energy storage device 240, or a virtual button for supplying power only to the portable air conditioner, or a virtual button for charging the battery pack 244 in the energy storage device 240 and supplying power to the portable air conditioner at the same time, when the corresponding virtual button is pressed, the external power supply 220 can be controlled to charge only the battery pack 244, or to supply power only to the portable air conditioner, or to charge the battery pack 244 and to supply power to the portable air conditioner at the same time, respectively, so as to realize various power supply forms of the external power supply 220 to the energy storage device 240 and the portable air conditioner, and the specific power supply form can be selected according to the needs.

[0046] It should be noted that the charging control panel 245 can also be provided with an automatic conversion mode virtual button. When the automatic conversion mode virtual button is pressed, if it is detected that the battery pack 244 is fully charged during the charging process of the battery pack 244, the charging control panel 245 can also automatically change the charging mode, such as changing the charging mode of only charging the battery pack 244 to the power supply mode of only powering the portable air conditioner, or changing the mode of simultaneously charging the battery pack 244 and powering the portable air conditioner to the power supply mode of only powering the portable air conditioner; and when the connection between the external power supply 220 and the energy storage device 240 is suddenly disconnected, the automatic conversion mode in the charging control panel 245 can also immediately control the battery pack 244 to power the portable air conditioner through the second power supply interface 230.

[0047] In some embodiments, as shown in Figure 7 , the first linkage switch 250 and the second power supply interface 230 are in series, when the first power supply interface 210 is powered, that is, connected with the external power supply 220, the first linkage switch 250 is automatically disconnected, thereby causing the second power supply interface 230 to stop powering the portable air conditioner, to prohibit the conduction of the second power supply path.

[0048] Specifically, the first linkage switch 250 is arranged in the second power supply path and is linked with the first power supply interface 210. When the external power supply 220 is connected to the first power supply path, that is, the external power supply 220 is connected to the first power supply interface 210 through the connector, as shown in Figure 7 , the first linkage switch 250 is disconnected under the linkage action of the first power supply interface 210. The disconnection of the first linkage switch 250 prohibits the conduction of the second power supply path, that is, although the energy storage device 240 is connected to the second power supply interface 230 through the power supply output interface 241, the disconnection of the first linkage switch 250 causes the energy storage device 240 to stop powering the portable air conditioner, at this time, the portable air conditioner is only powered by the external power supply 220; when the connector of the external power supply 220 is pulled out of the first power supply interface 210, as shown in Figure 8 , the first linkage switch 250 is closed under the linkage action of the first power supply interface 210. The closure of the first linkage switch 250 causes the second power supply path to be re-conducted, and the energy storage device 240 resumes powering the portable air conditioner through the second power supply interface 230.

[0049] Thus, by arranging the first linkage switch in the second power supply interface, it is ensured that only one of the first power supply path formed by the first power supply interface and the external power supply or the second power supply path formed by the second power supply interface and the energy storage device powers the portable air conditioner during the working process.

[0050] In some embodiments, as shown in Figure 9As shown, the second linkage switch 260 and the first power supply interface 210 are connected in series. When the second power supply interface 230 is energized, that is, when it is connected to the energy storage device 240, the second linkage switch 260 is automatically disconnected, thereby causing the first power supply interface 210 to stop supplying power to the portable air conditioner, so as to prevent the first power supply path from being connected.

[0051] Furthermore, such as Figure 10 As shown, for the convenience of power supply system control, the second linkage switch 260 is set as a normally closed switch. The air conditioner body 100 is provided with a vertically penetrating guide groove below it. A movable block 270 is provided in the guide groove. The movable block 270 can move up and down along the guide groove during the use of the energy storage system 240 and the air conditioner body 100. The second linkage switch 260 is closed or opened under the linkage action of the movable block 270. That is to say, when the second power supply interface 230 is connected to the energy storage device 240, the movable block 270 will open the normally closed switch (second linkage switch 260) during the upward movement.

[0052] Specifically, when the external power supply 220 connector is connected to the first power supply interface 210, such as Figure 10 As shown, the second linkage switch 260, as a normally closed switch, does not affect the power supply of the external power supply 220 to the portable air conditioner. However, when the power output interface 241 of the energy storage device 240 is plugged into the second power supply interface 230, as... Figure 9 As shown, the movable block 270 located below the air conditioner body 100 slides upward under the action of the upper surface of the energy storage device 240. The second linkage switch 260 is disconnected under the linkage action of the sliding block 270, thereby causing the external power supply 220 to stop supplying power to the portable air conditioner. The first power supply path is disconnected, and only the second power supply path formed by the energy storage device 240 and the second power supply interface 230 ensures that the portable air conditioner is powered. When the energy storage device 240 is separated from the air conditioner body 100, the second power supply path is disconnected, the movable block 270 returns to the initial position, and the second linkage switch 260 also returns to the normally closed state. The first power supply path is reconnected, realizing the external power supply 220 to supply power to the portable air conditioner.

[0053] Therefore, by setting a second linkage switch at the first power supply interface, it is ensured that during operation, only one power supply path, either the first power supply path formed by the first power supply interface and the external power source or the second power supply path formed by the second power supply interface and the energy storage device, powers the portable air conditioner.

[0054] In some embodiments, such as Figure 11As shown, the air conditioner body 100 is further provided with a power supply circuit 110, which comprises a first conversion module 111, a second conversion module 112, a first intelligent power module 113 and a second intelligent power module 114. The first conversion module 111 converts an external power supply into a first direct current for output. The input end of the second conversion module 112 is connected with the output end of the first conversion module 111 and the second power supply interface 230 respectively. The second conversion module 112 is used for converting the first direct current into a second direct current for output, or converting a third direct current provided by the energy storage device 240 into the second direct current for output when the energy storage device 240 is connected to the second power supply interface 230. The voltage of the second direct current is not greater than the voltage of the first direct current, and is not greater than the voltage of the third direct current. The first intelligent power module 113 is used for supplying power to the compressor according to the first direct current, or supplying power to the compressor according to the third direct current provided by the energy storage device 240. The input end of the second intelligent power module 114 is connected with the output end of the second conversion module 112. The second intelligent power module 114 can supply power to the fan in the portable air conditioner through the converted second direct current.

[0055] It should be noted that the intelligent power module is an advanced power switching device, which has the advantages of high current density, low saturation voltage and high voltage resistance of GTR (high power transistor), and the advantages of high input impedance, high switching frequency and low driving power of MOSFET (field effect transistor). Moreover, the intelligent power module integrates logic, control, detection and protection circuits inside, which is convenient to use, reduces the size and development time of the system, greatly enhances the reliability of the system, and is suitable for the development direction of modularization, compounding and power integrated circuit of power devices today, and has been widely used in the field of power electronics.

[0056] Specifically, when the external power supply 220 is used to supply power to the air conditioner body 100, the working current input by the external power supply 220 is converted into first direct current by the first conversion module 111, and is transmitted to the second conversion module 112 and the first intelligent power module 113 respectively. The first intelligent power module 113 supplies power to the compressor in the portable air conditioner based on the first direct current, and the second conversion module 112 converts the first direct current into second direct current and transmits the second direct current to the second intelligent power module 114 to drive the second intelligent power module 114 to supply power to the fan in the portable air conditioner. If the energy storage device 240 is connected to the second power supply interface 230 at this time, the external power supply 220 will immediately stop supplying power to the air conditioner body 100, so that only one power supply can supply power to the air conditioner body 100, that is, only the energy storage device 240 supplies power to the air conditioner body 100. At this time, the third direct current input by the energy storage device 240 will be transmitted to the second conversion module 112 and the first intelligent power module 113 respectively, and the first intelligent power module 113 will supply power to the compressor in the portable air conditioner according to the third direct current, and the second conversion module 112 will convert the third direct current into second direct current and transmit the second direct current to the second intelligent power module 114 to drive the second intelligent power module 114 to supply power to the fan in the portable air conditioner. If the connection between the energy storage device 240 and the second power supply interface 230 is disconnected again, the external power supply 220 will immediately resume supplying power to the air conditioner body 100, that is, the first direct current converted by the first conversion module 111 is continued to be used as the power supply for driving the air conditioner body 100 to operate.

[0057] When the energy storage device 240 is used to supply power to the air conditioner body 100, the third direct current input by the energy storage device 240 is transmitted to the second conversion module 112 and the first intelligent power module 113 respectively. The first intelligent power module 113 supplies power to the compressor in the portable air conditioner according to the third direct current, and the second conversion module 112 converts the third direct current into the second direct current and transmits the second direct current to the second intelligent power module 114 to drive the second intelligent power module 114 to supply power to the fan in the portable air conditioner. If the external power supply 220 is connected through the first power supply interface 210 at this time, the energy storage device 240 will immediately stop supplying power to the air conditioner body 100, ensuring that only one power supply can supply power to the air conditioner body 100, that is, only the external power supply 220 supplies power to the air conditioner body 100. At this time, the working current input by the external power supply 220 is converted into the first direct current by the first conversion module 111 and transmitted to the second conversion module 112 and the first intelligent power module 113 respectively. The first intelligent power module 113 supplies power to the compressor in the portable air conditioner based on the first direct current, and the second conversion module 112 converts the first direct current into the second direct current and transmits the second direct current to the second intelligent power module 114 to drive the second intelligent power module 114 to supply power to the fan in the portable air conditioner.
