[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0061] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0062] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0063] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0064] For ease of description, spatial relative terms may be used in this text to describe the relationship of one element or feature relative to another element or feature as shown in the figures. These relative terms include, for example, "bottom," "front," "upper," "tilted," "lower," "top," "inner," "horizontal," "outer," etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation, other than those depicted in the figures. For example, if the mechanism in the figure is flipped, then an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The invention is described below with reference to the accompanying drawings and specific embodiments:

[0065] refer to Figure 1 As shown, an embodiment of the present invention provides an air conditioner 300, including: an energy storage device 330, a jet driving device 340, and a flow splitting device 350.

[0066] Among them, such as Figure 1As shown, the energy storage device 330 is used to contain the energy storage material; the jet drive device 340 is assembled on the energy storage device 330; the diversion device 350 is connected to the energy storage device 330 through the jet drive device 340. When the jet drive device 340 applies a force to the energy storage device 330, the energy storage device 330 jets the energy storage material into the diversion device 350, and the jetted energy storage material is dispersed and ejected in the diversion device 350 to release thermal or cold energy.

[0067] Specifically, the energy storage material can be a phase change energy storage material. For air conditioner 300, which is a refrigeration air conditioner, the energy storage device 330 contains a phase change cold storage material. For air conditioner 300, which is a heat pump air conditioner, the energy storage device 330 contains a phase change heat storage material. Specifically, the phase change energy storage material contained in the energy storage device 330 is a reactive heating or cooling material, which can be: a solid (nitrate, lithium bromide, etc.) or liquid solute (such as ammonia) fused with water for cooling, or quicklime oxidation for heat release.

[0068] In some implementations, in order to store phase change energy storage materials, the energy storage device 330 includes: a sealed tank 331 and a liquid spraying pipe 332. The sealed tank 331 is filled with phase change cold storage or phase change heat storage materials under high pressure. The liquid inlet of the liquid spraying pipe 332 is connected to the sealed tank 331, and the liquid outlet of the liquid spraying pipe 332 is connected to the diversion device 350. The spraying drive device 340 is mounted on the liquid spraying pipe 332 and can apply force to the liquid spraying pipe 332 to spray the phase change energy storage materials from the sealed tank 331 through the liquid spraying pipe 332 to the diversion device 350.

[0069] In some embodiments, the injection drive device 340 includes: an opening adjustment member 341 and a first motor 342. The opening adjustment member 341 is mounted on the injection pipe 332 of the energy storage device 330. The first motor 342 is connected to the opening adjustment member 341, and the operation of the first motor 342 is used to adjust the opening of the opening adjustment member 341 to change the flow rate of the energy storage material injected from the injection pipe 332 to the diversion device 350.

[0070] Specifically, the opening adjustment component 341 can be a device that adjusts the opening evenly by pressing. This device can be a stroke-type structure, a knob-type structure, or other structures that allow the opening of the spray pipe 332 to be adjusted by pressing. All of the above-mentioned opening adjustment components 341 can achieve uniform opening adjustment by being driven by the operation of the first motor 342. The larger the opening of the opening adjustment component 341, the greater the flow rate of the energy storage material injected into the distribution device 350 through the spray pipe 332, and the better the cooling or heating effect of the air conditioner. Conversely, the smaller the opening, the smaller the flow rate of the energy storage material injected into the distribution device 350 through the spray pipe 332, thereby achieving the adjustment of the cooling and heating effect.

[0071] In some embodiments, the air conditioner 300 of the present invention further includes a control device 310 electrically connected to the first motor 342. The control device 310 controls the operation of the first motor 342, thereby accurately controlling the opening adjustment component 341 to uniformly adjust the opening, and thus precisely controlling the flow rate of the energy storage device 330 spraying energy storage material into the diversion device 350.

[0072] It should be understood that the first motor 342 can be any of the following motors: single-phase asynchronous motor, induction motor, brushed DC motor, single-phase brushless DC motor, three-phase brushless DC motor, three-phase permanent magnet synchronous motor, synchronous reluctance motor, and switched reluctance motor. The choice can be made according to actual needs and is not restricted here.

[0073] In some implementations, such as Figure 1 As shown, the air conditioner 300 provided in this embodiment of the invention also includes a fan 360. The fan 360 is arranged opposite to the distribution device 350. The operation of the fan 360 is used to drive the airflow at the location of the distribution device 350. The airflow drives the flow of cold or heat energy released by the distribution device 350, which exchanges heat with the environment, thereby allowing the cold / heat released by the energy storage material of the distribution device 350 to be transferred further. The fan 360 blows air to the distribution device 350, which can increase the speed of airflow through the distribution device 350. Therefore, the cold / heat released by the energy storage material of the distribution device 350 can be transferred further, expanding the range of air conditioning operation.

[0074] For details, please refer to Figure 4 , Figure 5 As shown, in order to precisely control the operation of the fan 360, the control device 310 is electrically connected to the second motor 361 of the fan 360. The control device 310 is used to control the operation of the second motor 361, thereby controlling the angle and / or air volume of the fan 360 facing away from or towards the splitter 350, so as to change the air flow speed at the location of the splitter 350, thereby increasing the heat exchange speed and improving the comfort of air conditioning.

[0075] It should be understood that the second motor 361 of the fan 360 can be any one of the following: single-phase asynchronous motor, induction motor, brushed DC motor, single-phase brushless DC motor, three-phase brushless DC motor, three-phase permanent magnet synchronous motor, synchronous reluctance motor, or switched reluctance motor.

[0076] Specifically, such as Figure 1As shown, the diversion device 350 in this embodiment of the invention includes multiple parallel diversion sub-pipes 351. Each diversion sub-pipe 351 is connected to the spray port of the spray pipe 332. The diversion sub-pipes 351 are spaced apart or in contact with each other, so as to disperse the energy storage material through the diversion device 350 as much as possible and increase the range of cold or heat energy released by the sprayed energy storage material.

[0077] It should be noted that the Air Conditioner 300 can be powered by either wired or wireless power. The wired power supply method will not be detailed here; please refer to relevant technical documentation. The wireless power supply technology of the Air Conditioner 300 is described below:

[0078] In some implementations, to enable the air conditioner 300 to be wirelessly powered, it is not necessary to directly connect the air conditioner 300 to the power grid via a point-to-point metal wire; instead, it can be used at a location far from the power grid port. (Reference) Figure 2 and Figure 3 As shown, the air conditioner 300 provided in this embodiment of the invention may further include: a receiving coil Lr1, used to receive electrical energy wirelessly transmitted by an external power supply device; wherein, the external power supply device may be a wireless charging device 100 or a wireless energy storage device 200. Specifically, the wireless charging device 100 may wirelessly transmit grid power when connected to the grid, and the wireless energy storage device 200 may capture and store the electrical energy wirelessly transmitted by the wireless charging device 100, so as to wirelessly supply power to the air conditioner 300 when it needs power, or the air conditioner 300 may directly capture the electrical energy wirelessly transmitted by the wireless charging device 100 to supply power to the load.

[0079] The receiving coil Lr1 is electrically connected to the control device 310. The control device 310 is used to convert the electrical energy received by the receiving coil Lr1 from the wireless charging device 100 or the wireless energy storage device 200, which is wirelessly transmitted. The converted electrical energy is used to supply power to the load of the air conditioner 300. The load of the air conditioner 300 may include at least the first motor 342.

[0080] In some implementations, to improve the portability of the air conditioner 300, so that the air conditioner 300 is not limited by the application scenario, it can be used offline and easily moved, for example, in an indoor kitchen or balcony, or in outdoor tents or fishing scenarios. (Reference) Figure 2 As shown, the air conditioner 300 provided in this embodiment of the invention may further include a battery pack 320.

[0081] The battery pack 320 is electrically connected to the control device 310. The control device 310 is used to convert the electrical energy received by the receiving coil Lr1 and store the converted electrical energy in the battery pack 320, or to convert the electrical energy released from the battery pack 320 and supply it to the load of the air conditioner 300. The load of the air conditioner 300 may include at least the first motor 342. In addition to including the first motor 342, it may also include a second motor 361 and / or a display device 318.

[0082] Specifically, when the receiving coil Lr1 does not receive electrical energy wirelessly output from the external power supply device (electrical energy wirelessly transmitted by the wireless charging device 100 or the wireless energy storage device 200), the battery pack 320 releases electrical energy, and the control device 310 converts the electrical energy released by the battery pack 320 into the electrical energy required by the load of the air conditioner 300, and then supplies power to the corresponding load.

[0083] Specifically, when the receiving coil Lr1 receives external electrical energy, if the battery pack 320 needs to be charged, the control device 310 can convert the electrical energy received by the receiving coil Lr1 into electrical energy that can be stored in the battery pack 320 and store it in the battery pack 320; when the receiving coil Lr1 receives external electrical energy, if the air conditioner 30 needs to be powered, the control device 310 can also convert the electrical energy received by the receiving coil Lr1 into electrical energy required by the load of the air conditioner 300 and supply power to the corresponding load.

[0084] refer to Figure 4 As shown, in some embodiments, the control device 310 in this invention includes: an air conditioner controller 312, a wireless power receiving module 311, and a first inverter module 314.

[0085] The wireless power receiving module 311 is electrically connected to the air conditioning controller 312. The input end of the wireless power receiving module 311 is electrically connected to the receiving coil Lr1, and the output end of the wireless power receiving module 311 is electrically connected to the injection drive device 340 through the first inverter module 314. The first inverter module 314 is also electrically connected to the air conditioning controller 312. Thus, under the drive of the air conditioning controller 312 and the power supply of the wireless power receiving module 311, the first inverter module 314 controls the injection drive device 340 to act on the energy storage device 330, so that the energy storage device 330 injects energy storage material into the diversion device 350.

[0086] In some implementations, refer to Figure 4 As shown, the control device 310 may further include a second inverter module 315 for controlling the fan 360.

[0087] Specifically, the second inverter module 315 is electrically connected to the air conditioner controller 312 and the wireless power receiving module 311. Under the drive of the air conditioner controller 312 and the power supply of the wireless power receiving module 311, the second inverter module 315 controls the operation of the fan 360 so that the fan 360 discharges air away from or towards the diversion device 350 and / or controls the air volume.

[0088] Combination Figure 6 As shown, the second inverter module 315 can be an IPM2 (Intelligent Power Module) power device. Similarly, the first inverter module 314 can be an IPM1 power device, or more simply, it can be replaced by other types of transistors, to control whether the first motor 342 and the second motor 361 are running, but not to control the specific operating parameters of the first motor 342 and the second motor 361.

[0089] In order to drive the first motor 342, the control device 310 further includes a first motor drive circuit 3124. The input terminal of the first motor drive circuit 3124 is electrically connected to the control terminal of the first inverter module 314, and the output terminal of the first motor drive circuit 3124 is electrically connected to the control chip 3121. Under the pulse signal output by the control chip 3121, the first motor drive circuit 3124 drives the first motor 342 to operate.

[0090] To drive the second motor 361, the control device 310 further includes a second motor drive circuit 3125. The input terminal of the second motor drive circuit 3125 is electrically connected to the control terminal of the second inverter module 315, and the output terminal of the second motor drive circuit 3125 is electrically connected to the control chip 3121. The second motor drive circuit 3125 is activated by the pulse signal output by the control chip 3121.

[0091] Specifically, the wireless power receiving module 311 includes a bridge rectifier circuit 3111 and a power receiving voltage regulating circuit 3112. The AC input terminal of the bridge rectifier circuit 3111 is electrically connected to the receiving coil Lr1. The AC input terminal of the bridge rectifier circuit 3111 is electrically connected to the receiving coil Lr1 to rectify the electrical energy received by the receiving coil Lr1. The input terminal of the power receiving voltage regulating circuit 3112 is electrically connected to the output terminal of the bridge rectifier circuit 3111, and the output terminal of the power receiving voltage regulating circuit 3112 is electrically connected to the input terminals of the first inverter module 314 and the second inverter module 315. The power receiving voltage regulating circuit 3112 is used to boost or buck the electrical energy output from the bridge rectifier circuit 3111 and transmit the bucked electrical energy to the input terminals of the first inverter module 314 and the second inverter module 315.

[0092] like Figure 6As shown, the bridge rectifier circuit 3111 is used to convert the electrical energy received by the receiving coil Lr1 from AC to DC to DC bus voltage +VDC1; after the DC bus voltage +VDC1 is further converted by the voltage regulator circuit 3112 (boost or buck), the DC bus voltage +VDC2 required by the first inverter module 314 and / or the second inverter module 315 is obtained.

[0093] refer to Figure 6 As shown, in some embodiments, the bridge rectifier circuit 3111 may include a resonant capacitor C, a bridge rectifier, and a first filter capacitor E1. One end of the resonant capacitor C is electrically connected to one AC input terminal of the bridge rectifier, and the other end of the resonant capacitor C is electrically connected to one end of the receiving coil Lr1. The other AC input terminal of the bridge rectifier is electrically connected to the other end of the receiving coil Lr1. The two DC output terminals of the bridge rectifier are electrically connected to the positive and negative terminals of the first filter capacitor E1, respectively, and the negative terminal of the first filter capacitor E1 is grounded.

[0094] Among them, the bridge rectifier can be any of the hardware topologies of a full-bridge synchronous rectifier, a half-bridge synchronous rectifier, and an uncontrolled rectifier.

[0095] For example, refer to Figure 6 As shown, the bridge rectifier can be a full-bridge synchronous rectifier composed of a first power device Q1, a second power device Q2, a third power device Q3, and a fourth power device Q4. The power devices Q1, Q2, Q3, and Q4 can be any type of transistor, such as an IGBT (Insulated Gate Bipolar Transistor), a MOSFET, or a bipolar transistor.

[0096] To drive the bridge rectifier circuit 3111, the air conditioner controller 312 includes: a control chip 3121; and a rectifier drive circuit 3122. The input terminal of the rectifier drive circuit 3122 is electrically connected to the control chip 3121, and the output terminal of the rectifier drive circuit 3122 is electrically connected to the bridge rectifier circuit 3111. Specifically, the rectifier drive circuit 3122 is electrically connected to the gate control terminal of each power device Q1, Q2, Q3, and Q4 in the bridge rectifier circuit 3111 to control the on / off state of the power devices Q1, Q2, Q3, and Q4.

[0097] Specifically, the power receiving voltage regulation circuit 3112 can be a separate boost circuit, a separate buck circuit, or both buck and boost circuits, or a buck-boost multiplexed circuit. In practical applications, the power receiving voltage regulation circuit 3112 may not be provided; that is, the wireless power receiving module 311 may only have a bridge rectifier circuit 3111, and the output of the bridge rectifier circuit 3111 may be directly electrically connected to the first inverter module 314 and the second inverter module 315.

[0098] For example, refer to Figure 6 As shown, the voltage regulating circuit 3112 can be a step-up / step-down multiplexing circuit composed of the fifth power device Q5, the first inductor L2, the sixth power device Q6, and the second filter capacitor E2. The negative terminal of the second filter capacitor E2 is grounded. By switching the fifth power device Q5 and the sixth power device Q6 on and off, the step-up or step-down processing can be achieved.

[0099] Correspondingly, in order to drive the powered voltage regulating circuit 3112, refer to Figure 6 As shown, the air conditioner controller 312 also includes a voltage regulating drive circuit 3123. The input terminal of the voltage regulating drive circuit 3123 is electrically connected to the control chip 3121, and the output terminal of the voltage regulating drive circuit 3123 is electrically connected to the control terminal of each power device Q5 and Q6 in the powered voltage regulating circuit 3112, so as to control the on and off of the fifth power device Q5 and the sixth power device Q6.

[0100] In some embodiments, the air conditioner 300 provided in this invention includes an air conditioner communication module 316, electrically connected to an air conditioner controller 312. The air conditioner communication module 316 is used to communicate with an external power supply device that wirelessly supplies power to the air conditioner 300, controlling the external power supply device to be in standby or power transmission mode. Specifically, the air conditioner communication module 316 can be one or more of a Bluetooth module, signal carrier module, infrared transceiver module, Wi-Fi module, mobile communication module, radio frequency module, and radio module.
