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.

[0069] 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.

[0070] 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.

[0071] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0072] Or it may implicitly indicate the number of indicated technical features. Thus, features defined with "first," "second," etc., 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.

[0073] 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.

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:

[0074] refer to Figure 1 As shown, an embodiment of the present invention provides an air conditioner 300, including: an energy storage device 330, a jetting device 392, and an atomizing device 393.

[0075] Among them, such as Figure 1 As shown, the energy storage device 330 is used to contain the energy storage material; the spraying device 392 is connected to the energy storage device 330; and the atomizing device 393 is connected to the spraying device 392. When the spraying device 392 acts on the energy storage device 330, it draws the energy storage material out of the energy storage device 330 and sprays it toward the atomizing device 393. The atomizing device 393 atomizes the sprayed energy storage material to release thermal or cold energy.

[0076] Specifically, the phase change energy storage material contained in the energy storage device 330 is liquid. If the air conditioner 300 is a refrigeration air conditioner, the energy storage device 330 contains a cold storage phase change material. If the air conditioner 300 is a heat pump air conditioner, the energy storage device 330 contains a heat storage phase change material.

[0077] In some implementations, in order to preserve the energy storage phase change material, the energy storage device 330 is a sealed tank, which is filled with cold or heat storage phase change energy storage material under high pressure.

[0078] In some implementations, in order to facilitate the addition of energy storage phase change material, the energy storage device 330 is equipped with an energy storage material adding device 394. When the phase change energy storage material is consumed, the energy storage phase change material can be refilled through the energy storage material adding device 394.

[0079] In some embodiments of the present invention, the air conditioner 300 further includes a liquid injection pipe 332, the inlet of which is connected to the energy storage device 330, and the outlet of the liquid injection pipe 332 is connected to the injection device 392. Furthermore, a control valve 395 is fitted to the liquid injection pipe 332 to control the flow of the energy storage material in the liquid injection pipe 332. Specifically, when the air conditioner 300 stops working, the control valve 395 closes, blocking the energy storage material. When the air conditioner 300 is running, the control valve 395 opens, allowing the energy storage material to flow.

[0080] The spraying device 392 is mounted on the spraying pipe 332 and can apply force to the spraying pipe 332 to spray the energy storage phase change material from the sealed tank through the spraying pipe 332 to the atomizing device 393.

[0081] In some embodiments, the injection device 392 includes: a pressurized absorption device 3921, a first motor 342, and a pressurized injection device 3922. The pressurized absorption device 3921 is mounted on the liquid spraying pipe 332 of the energy storage device 330, and the control valve 395 is located between the energy storage device 330 and the pressurized absorption device 3921; the first motor 342 is connected to the pressurized absorption device 3921, and the operation of the first motor 342 drives the pressurized absorption device 3921 to draw out the energy storage material from the energy storage device 330; the pressurized injection device 3922 pressurizes the drawn-out energy storage material to form a high-speed, high-pressure gas, and sprays it toward the atomizing device 393.

[0082] Specifically, the booster absorption device 3921 is a booster jet pump structure, which can be any type of rotary pump or reciprocating pump. The structure of the booster absorption device 3921 can be driven by the operation of the first motor 342.

[0083] 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 driving the operation of the pressurization absorption device 3921, and thus precisely controlling the flow rate of the energy storage material absorbed from the energy storage device 330.

[0084] 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.

[0085] In some implementations, such as Figure 1 As shown, the control device 310 and the control valve 395 are electrically connected and are used to control the opening and closing of the control valve 395.

[0086] In some embodiments, as Figure 1 shown, the air conditioner 300 provided by the embodiment of the present invention further includes a temperature detection device 396, which is disposed opposite to the atomization device 393, and the temperature detection device 396 is used to detect the temperature of the atomized energy storage material.

[0087] In order to better and accurately control the ambient temperature, the control device 310 is electrically connected to the temperature detection device 396, and the control device 310 is used to receive the temperature detected by the temperature detection device 396. Specifically, during the cooling operation, the temperature detection device 396 feeds back the temperature information T of the air outlet of the air conditioner 300 to the control device 310, and the control device 310 determines the relationship between the set temperature T0 and the temperature information T. When T0>T, the boosting absorption device 3921 is driven to operate at a reduced speed according to the predicted difference. When T0>T, the boosting absorption device 3921 is driven to operate at the preset maximum speed. Until T0=T, it operates stably with the set parameters. During the heating operation, the temperature detection device 396 feeds back the temperature information T of the air outlet of the air conditioner 300 to the control device 310, and the control device 310 determines the relationship between the set temperature T0 and the temperature information T. When T0<T, the boosting absorption device 3921 is driven to operate at a reduced speed according to the predicted difference. When T0>T, the boosting absorption device 3921 is driven to operate at the preset maximum speed until T0=T, and it operates stably with the set parameters.

[0088] In some embodiments, as Figure 1 shown, the air conditioner 300 provided by the embodiment of the present invention further includes a fan 360; the fan 360 is disposed opposite to the atomization device 393, and the fan 360 is used to drive the air flow at the atomization device 393, increasing the speed of the air flowing through the atomization device 393. Thus, the cold / heat released by the energy storage material of the atomization device 393 can be transmitted farther, expanding the scope of the air conditioner's function.

[0089] Specifically, referring to Figure 4 、 Figure 5 shown, in order to accurately control the operation of the fan 360, the control device 310 is electrically connected to the second motor 361 of the fan 360, and 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 air blown by the fan 360 towards the atomization device 393 to improve the comfort of the air conditioner.

[0090] It should be understood that the second motor 361 of the fan 360 can be any one of a single-phase asynchronous motor, an induction motor, a brushed DC motor, a single-phase brushless DC motor, a three-phase brushless DC motor, a three-phase permanent magnet synchronous motor, a synchronous reluctance motor, and a switched reluctance motor.

[0091] Specifically, as Figure 1As shown, the atomizing device 393 in this embodiment of the invention atomizes the ejected energy storage material into fine liquid particles to increase the propagation speed and area of ​​the cold / heat released by the energy storage material.

[0092] 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:

[0093] 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 wireless air conditioner 300 when it needs power, or the wireless air conditioner 300 may directly capture the electrical energy wirelessly transmitted by the wireless charging device 100 to supply power to the load.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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 spraying device 392 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 spraying device 392 to act on the energy storage device 330, so that the energy storage material is drawn out from the energy storage device 330 and sprayed onto the atomizing device 393.

[0101] 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.

[0102] 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 blows air toward the atomizing device 393 and / or controls the air volume.

[0103] Combination Figure 6As 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.

[0104] 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.

[0105] 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.

[0106] To better control the ambient temperature, the control chip 3121 is electrically connected to the control valve 395 and the temperature detection device 396. The control chip 3121 is used to control the opening and closing of the control valve 395 to control the flow of the energy storage material. During the cooling or heating process, the temperature detection device 396 transmits a temperature signal to the control chip 3121, and the control chip 3121 precisely controls the air conditioner 300 based on the received temperature signal.

[0107] 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 bridge rectifier circuit 3111 is used 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 by 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.

[0108] like Figure 6 As 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 (boosted or bucked) by the voltage regulating circuit 3112, the DC bus voltage +VDC2 required by the first inverter module 314 and / or the second inverter module 315 is obtained.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.
