Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this invention based on the specific circumstances.

[0024] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0025] like Figure 1 and Figure 2 As shown, a specific embodiment of the first aspect of the present invention provides an air conditioner. The air conditioner includes an outdoor unit 100 and a heating module 200; the heating module 200 is connected to the base plate 102 of the outdoor unit 100; the heating module 200 is used to heat the base plate 102.

[0026] In this embodiment, by setting a heating module 200 connected to the base plate 102, the base plate 102 can be heated, thereby solving the problem in the prior art that the outdoor unit 100 of the air conditioner is prone to frosting and difficult to defrost in winter in low-temperature and high-humidity areas.

[0027] Furthermore, the heating module 200 includes an electric heating component 210, a first heat release and heat storage component 220, and / or a second heat storage and heat release component; the electric heating component 210 is used to be electrically connected to a power source and is used to convert electrical energy into heat energy to heat the base plate 102; the first heat release and heat storage component 220 includes a phase change material; when the outdoor ambient temperature is lower than a first temperature threshold, the phase change material of the first heat release and heat storage component 220 undergoes a forward phase change to release heat for heating the base plate 102; when the outdoor ambient temperature is not lower than the first temperature threshold, the phase change material of the first heat release and heat storage component 220 undergoes a reverse phase change to store heat; the second heat release and heat storage component 230 includes a dielectric heat storage material; the second heat release and heat storage component 230 is used to be electrically connected to a power source and is used to apply an external electric field to the dielectric heat storage material.

[0028] In this embodiment, by providing an electric heating component 210, the heating of the base plate 102 can be controlled by energizing the electric heating module 200 as needed. By providing a first heat release and storage component 220 including a phase change material, the phase change characteristics of the phase change material can be utilized to enable the first heat release and storage component 220 to automatically release and store heat according to the external temperature, thereby achieving automatic heating of the base plate 102. By providing a second heat release and storage component 230 including a dielectric heat storage material, the properties of the dielectric heat storage material can be utilized, and by changing the positive and negative terminals connected to the second heat release and storage component 230, the dielectric heat storage material can release and store heat, thereby achieving heating of the base plate 102.

[0029] Furthermore, the electric heating module 200 includes a resistance wire; the resistance wire can be laid on the upper side of the base plate 102, in other words, the resistance wire is located inside the casing of the outdoor unit 100, and is used to directly heat the ice or frost on the base plate 102 to improve heating efficiency.

[0030] Furthermore, the first heat release and heat storage component 220 includes a first thermally conductive outer shell; a phase change material is filled inside the first thermally conductive outer shell. The first thermally conductive outer shell can be disposed on the lower side of the base plate 102. When the outdoor ambient temperature is lower than a first temperature threshold, the phase change material of the first heat release and heat storage component 220 changes from a solid phase to a liquid phase to release heat for heating the base plate 102; when the outdoor ambient temperature is not lower than the first temperature threshold, the phase change material of the first heat release and heat storage component 220 changes from a liquid phase to a solid phase to store heat. In this way, the first heat release and heat storage component 220 can automatically heat the base plate 102 according to the outdoor ambient temperature.

[0031] It is understood that phase change materials are existing technologies, and their types are not limited in the specific embodiments of this invention. For example, the phase change material can be a composite phase change energy storage and cold storage material. A composite phase change energy storage and cold storage material is a composite phase change material composed of various inorganic salts (such as sodium sulfate decahydrate, potassium chloride, ammonium sulfate, etc.) and other additives (such as nucleating agents, thickeners, suspending agents, etc.). This material can achieve a specific phase change temperature (such as 8~10 degrees Celsius) by adjusting the proportions of its components, and has advantages such as high energy storage density, low subcooling, and good stability. It can be applied in fields such as cold chain transportation and air conditioning phase change cold storage systems.

[0032] Furthermore, the second heat release and storage component 230 includes a second outer shell; a dielectric heat storage material is filled inside the second outer shell; the second outer shell includes a side panel and two end plates; the two end plates are arranged at intervals, and the two ends of the side panel are respectively connected to the two end plates. The end plates are metal plates, and the side panels can be plastic plates; the two end plates are respectively electrically connected to the positive and negative terminals of the power supply; by changing the correspondence between the two end plates and the positive and negative terminals of the power supply, the electric field between the two end plates can be changed, thereby allowing the dielectric heat storage material to release and store heat.

[0033] It is understood that dielectric thermal storage materials are existing technologies, and their types are not limited in the specific embodiments of this invention. Dielectric thermal storage materials include ferroelectric materials, dielectric polymer materials, polyethylene oxide (PEO), or ceramic dielectric materials. Ferroelectric materials not only possess spontaneous polarization, but also have two or more possible orientations of spontaneous polarization. The intensity of spontaneous polarization can change direction with the direction of the applied electric field. This characteristic enables ferroelectric materials to generate significant electrothermal effects when the polarity of the electric field changes. Typical ferroelectric materials include barium titanate (BaTiO3) and lead zirconate titanate (PZT). These materials have high dielectric constants and large electrothermal effects, thus possessing potential application value in refrigeration technology.

[0034] In some embodiments, the air conditioner further includes a solar photovoltaic panel 300; the solar photovoltaic panel 300 is disposed on the side of the outdoor unit 100 near the air outlet 101; the solar photovoltaic panel 300 is electrically connected to the heating module 200 for supplying power to the heating module 200; or / and, the solar photovoltaic panel 300 is electrically connected to the outdoor unit 100 for supplying power to the outdoor unit 100.

[0035] In this embodiment, by setting up a solar photovoltaic panel 300, the heating module 200 can be powered by mains electricity, which is in line with the trend of low carbon and energy conservation. By setting the solar photovoltaic panel 300 on the side of the outdoor unit 100 near the air outlet 101, the fan of the outdoor unit 100 can be used to dissipate heat from the solar photovoltaic panel 300, thereby improving the power generation efficiency of the solar photovoltaic panel 300.

[0036] Furthermore, the air conditioner also includes an energy storage module; the input of the energy storage module is electrically connected to the solar photovoltaic panel 300 for storing electrical energy; the output of the energy storage module is electrically connected to the heating module 200 and / or the outdoor unit 100. Solar energy is a clean and renewable energy source. Utilizing the solar photovoltaic panel 300 to generate electricity and storing it through the energy storage module can significantly reduce dependence on traditional energy sources, lower carbon emissions, and achieve green energy conservation. This design helps protect the environment, reduces energy consumption, and aligns with the concept of sustainable development. The solar photovoltaic panel 300 can generate some or all of the electricity needed by the air conditioner, thereby reducing electricity costs. Especially in areas with abundant sunshine, this design can significantly reduce the operating costs of the air conditioner. In addition, the energy storage module can provide backup power during periods of low sunlight or when the power grid fails, ensuring the normal operation of the air conditioner and improving overall economic efficiency. The solar photovoltaic panel 300 converts solar energy into electrical energy, while the energy storage module stores excess electrical energy for use when needed. This design ensures maximum energy utilization and avoids energy waste. The design of the energy storage module allows the air conditioner to adapt more flexibly to different environments and needs. Furthermore, the energy storage module can be combined with other renewable energy systems (such as wind and hydropower) to further enhance the system's flexibility and adaptability.

[0037] like Figure 3 As shown, the air conditioner also includes a first angle adjustment module 400; the first angle adjustment module 400 includes a support component 410 and a first angle driving component 420; the support component 410 is hinged to the solar photovoltaic panel 300 via a first hinge shaft 430; the first hinge shaft 430 intersects the vertical direction; the first angle driving component 420 is installed on the support component 410, and the driving end of the first angle driving component 420 is hinged to the solar photovoltaic panel 300 via a second hinge shaft 440, for driving the solar photovoltaic panel 300 to rotate around the first hinge shaft 430, so that the solar photovoltaic panel 300 switches between an unfolded state and a retracted state; the central axis of the second hinge shaft 440 is parallel to the central axis of the first hinge shaft 430.

[0038] In this embodiment, the solar photovoltaic panel 300 can be adjusted according to the position and angle of the sun via the first angle adjustment module 400, ensuring that the solar photovoltaic panel 300 always faces the sun, thereby maximizing solar energy absorption. The position and angle of the sun vary at different times and seasons. The first angle adjustment module 400 can automatically or manually adjust the angle of the photovoltaic panel to adapt to these changes, improving solar energy capture efficiency. The first angle adjustment module 400 allows the solar photovoltaic panel 300 to easily switch between extended and retracted states, increasing system flexibility. In severe weather conditions (such as strong winds, heavy rain, etc.), the photovoltaic panel can be retracted to protect it from damage while ensuring the normal operation of the air conditioner. When solar energy is not needed, the photovoltaic panel can also be retracted to save space or reduce visual interference. By precisely adjusting the angle of the photovoltaic panel, the generated electricity can be managed more effectively, ensuring it matches the energy demand of the air conditioner. When there is excess electricity, it can be stored in the energy storage module for unforeseen needs. This energy management strategy helps reduce energy consumption and costs.

[0039] Specifically, the first angle driving component 420 includes two telescopic driving assemblies 421. The two telescopic driving assemblies 421 are symmetrically arranged on the left and right sides of the supporting component 410, with their upper ends symmetrically arranged relative to the first hinge axis 430. The upper ends of the telescopic driving assemblies 421 are hinged to the solar photovoltaic panel 300 via a second hinge axis 440, and the lower ends of the telescopic driving assemblies 421 are hinged to the supporting component 410 via another second hinge axis 440. When the telescopic driving assemblies 421 extend or retract, they drive the solar photovoltaic panel 300 to rotate around the first hinge axis 430 and the second hinge axis 440. The use of two telescopic driving assemblies 421 improves the movement stability of the solar photovoltaic panel 300.

[0040] Specifically, the telescopic drive assembly 421 includes a cylinder or an electric telescopic rod.

[0041] Specifically, the support component 410 includes a support rod, the upper end of which has a mounting portion; the mounting portion is hinged to the solar photovoltaic panel 300 via a first hinge shaft 430.

[0042] like Figure 4 As shown, the air conditioner also includes an indoor unit and a cleaning module; the indoor unit is equipped with a water tray 510 for collecting condensate; the water tray 510 is connected to the cleaning module through a first water inlet pipe 610 for supplying condensate to the cleaning module; and / or the outdoor unit 100 is connected to the cleaning module through a second water inlet pipe 620 for supplying defrosting water to the cleaning module; the outlet of the cleaning module faces the solar photovoltaic panel 300 for spraying water onto the solar photovoltaic panel 300 to clean the solar photovoltaic panel 300.

[0043] In this embodiment, by setting up a cleaning module, the solar photovoltaic panel 300 can be cleaned periodically, preventing dust accumulation on the solar photovoltaic panel 300 and improving its power generation efficiency. By supplying condensate and defrosting water to the cleaning module, water can be reused, saving water resources.

[0044] Specifically, the cleaning module includes a nozzle 640 and a water pump 630; the outlet of the nozzle 640 faces the solar photovoltaic panel 300; the outlet of the water pump 630 is connected to the inlet of the nozzle 640, and the inlet of the water pump 630 is connected to the drip tray 510 through a first inlet pipe 610, and the inlet of the water pump 630 is also connected to the outdoor unit 100 through a second inlet pipe 620. When the water pump 630 starts, it draws the condensate and / or defrost water collected in the drip tray 510 to the nozzle 640, which then sprays the water onto the solar photovoltaic panel 300.

[0045] In some embodiments, the air conditioner further includes a mounting platform; the mounting platform is rotatably engaged with the outdoor unit 100 via a second angle adjustment module; the outdoor unit 100 is connected to the indoor unit via a flexible hose for delivering refrigerant. For example, the position of the outdoor unit 100 relative to the sun can be adjusted via the second angle adjustment module, so that the air outlet 101 of the outdoor unit 100 faces the sun in summer and in winter.

[0046] Specifically, the second angle adjustment module includes a slewing platform.

[0047] A specific embodiment of the second aspect of the present invention provides a control method for an air conditioner. The following description uses a control device as the executing entity of the control method for the air conditioner. This control method for the air conditioner is used in any of the above embodiments. The control method for the air conditioner includes: When the outdoor ambient temperature is lower than the first temperature threshold, the heating module 200 is turned on to heat the base plate 102.

[0048] Specifically, when the outdoor ambient temperature is lower than the first temperature threshold, the first heat release and heat storage component 220 automatically releases heat to heat the base plate 102.

[0049] Specifically, when the outdoor ambient temperature is lower than the first temperature threshold, the solar photovoltaic panel 300 can directly supply power to the electric heating component 210, causing the electric heating component 210 to heat up and heat the base plate 102.

[0050] Specifically, when the outdoor ambient temperature is lower than the first temperature threshold, the solar photovoltaic panel 300 can directly supply power to the second heat release and heat storage component 230, causing the second heat release and heat storage component 230 to release heat, thereby heating the base plate 102.

[0051] It is understandable that the first temperature threshold is preset in the control device.

[0052] In some embodiments, the control method for the air conditioner further includes: When the outdoor ambient temperature is not lower than the first temperature threshold for a continuous period of time that is not less than the first time threshold, the solar photovoltaic panel 300 is controlled to prioritize power supply to the energy storage module. When the energy storage module is fully loaded, or when the outdoor ambient temperature is below the first temperature threshold, the solar photovoltaic panel 300 supplies power to the heating module 200.

[0053] In this embodiment, prioritizing power supply to the energy storage module when the outdoor ambient temperature is high and sustained for a period of time ensures sufficient energy storage for unforeseen needs, especially during power outages or insufficient sunlight. When the energy storage module is fully loaded, the solar photovoltaic panel 300 switches to powering the heating module 200, avoiding energy waste and achieving efficient energy utilization. This strategy of prioritizing power supply to the energy storage module helps provide backup power during grid failures or insufficient sunlight, enhancing system reliability. Intelligent management of the power supply targets of the solar photovoltaic panel 300 can prevent system failures or damage caused by improper energy allocation.

[0054] In some embodiments, the control method for the air conditioner further includes: During the daytime, the target angle of the solar photovoltaic panel 300 is determined based on the current time, and the operation of the first angle drive component 420 is controlled to rotate the solar photovoltaic panel 300 to the target angle. At night, the first angle drive component 420 is reset, causing the solar photovoltaic panel to return from the unfolded state to the retracted state.

[0055] In this embodiment, by adjusting the angle of the solar photovoltaic panel 300° according to the current time, it can be ensured that the photovoltaic panel is always in the optimal position facing the sun, thereby maximizing solar energy capture. This dynamic adjustment helps improve the power generation efficiency of the photovoltaic panel and increase the generated electricity. The control method allows the photovoltaic panel to automatically adjust its state (expanded and retracted) according to sunlight conditions (day and night). This flexibility helps adapt to different environmental conditions and ensures stable system operation. At night or when there is insufficient sunlight, resetting the photovoltaic panel to the retracted state can reduce wind resistance and reduce potential damage to the photovoltaic panel caused by severe weather conditions such as strong winds. This protective measure helps extend the service life of the photovoltaic panel.

[0056] Specifically, during the daytime, based on the current time, the target angle of the solar photovoltaic panel 300 is determined to control the operation of the first angle drive component 420, causing the solar photovoltaic panel 300 to rotate to the target angle, including: Determine the current position of the sun based on local latitude, longitude, date, and time; Determine the target angle of the solar photovoltaic panel 300 based on the position of the sun; The rotation angle of the solar photovoltaic panel 300 is determined based on the target angle and the current angle of the solar photovoltaic panel 300.

[0057] It can improve the rotational accuracy of the solar photovoltaic panel 300.

[0058] Specifically, when the difference between the target angle and the current angle is less than the difference threshold, the solar photovoltaic panel 300 does not need to be rotated.

[0059] In some embodiments, the control method for an air conditioner further includes: The target set temperature is determined based on the current light intensity and the set temperature difference; the set temperature difference is the difference between the indoor unit's set temperature and the set temperature threshold.

[0060] In this embodiment, the control method automatically adjusts the target set temperature based on real-time light intensity, making the air conditioner's operation more intelligent and adaptive. By intelligently adjusting the target set temperature, this control method helps optimize the air conditioner's energy consumption. When sunlight is strong, utilizing natural light reduces the need for air conditioning to cool or heat, thereby reducing energy consumption. This intelligent adjustment helps achieve energy conservation and emission reduction goals. The concept of a set temperature difference allows the system to adjust between the indoor unit's set temperature and a preset comfort temperature threshold. This fine-tuning ensures that the indoor temperature remains within the user's desired comfort range, improving the comfort of the living or working environment.

[0061] Furthermore, based on the current light intensity and the set temperature difference, the target set temperature is determined; the set temperature difference is the difference between the indoor unit's set temperature and the set temperature threshold, including: In cooling mode, if the light intensity is greater than the light intensity threshold and the set temperature difference is greater than the maximum value of the first difference threshold range, the set temperature is lowered by a first reduction amount, and the reduced set temperature is used as the target set temperature; subsequently, after the set temperature difference is within the first difference threshold range, the set temperature is reset to the initial set temperature.

[0062] In cooling mode, if the light intensity is greater than the light intensity threshold and the set temperature difference is less than the minimum value of the first difference threshold range, the set temperature is lowered by the second reduction amount, and the reduced set temperature is used as the target set temperature; subsequently, after the set temperature difference is within the first difference threshold range, the set temperature is reset to the initial set temperature; wherein, the second reduction amount is less than the first reduction amount.

[0063] In cooling mode, if the light intensity is less than the light intensity threshold and the set temperature difference is greater than the maximum value of the first difference threshold range, the set temperature will not be adjusted.

[0064] In cooling mode, if the light intensity is less than the light intensity threshold and the set temperature difference is less than the minimum value of the first difference threshold range, the set temperature is lowered by the second reduction amount, and the reduced set temperature is used as the target set temperature; subsequently, after the set temperature difference is within the first difference threshold range, the set temperature is reset to the initial set temperature.

[0065] In the heating module, if the light intensity is greater than the light intensity threshold and the set temperature difference is greater than the maximum value of the second difference threshold range, the set temperature is increased by the first increase amount, and the increased set temperature is used as the target set temperature; subsequently, after the set temperature difference is within the second difference threshold range, the set temperature is reset to the initial set temperature.

[0066] In the heating module, if the light intensity is greater than the light intensity threshold and the set temperature difference is less than the minimum value of the second difference threshold range, the set temperature is increased by a second decrease, and the increased set temperature is used as the target set temperature. Subsequently, after the set temperature difference falls within the second difference threshold range, the set temperature is reset to the initial set temperature. The second increase is less than the first increase.

[0067] In the heating module, if the light intensity is less than the light intensity threshold and the set temperature difference is greater than the maximum value of the second difference threshold range, the set temperature will not be adjusted.

[0068] In the heating module, if the light intensity is less than the light intensity threshold and the set temperature difference is less than the minimum value of the second difference threshold range, the set temperature is increased by the second increase amount, and the increased set temperature is used as the target set temperature; subsequently, after the set temperature difference is within the second difference threshold range, the set temperature is reset to the initial set temperature.

[0069] This design allows for advance adjustment of the air conditioner's cooling and heating efficiency, improving the user experience.

[0070] Preferably, the light intensity threshold can be between 1000 lux and 2000 lux.

[0071] In some embodiments, the control method of the air conditioner further includes: controlling the cleaning module to start at intervals of a second time threshold to achieve periodic cleaning of the solar photovoltaic panel 300.

[0072] In some embodiments, when the outdoor unit 100 is in standby mode, if the outdoor ambient temperature is within the third temperature threshold range and the light intensity is greater than the light intensity threshold, the fan of the outdoor unit 100 is turned on to dissipate heat from the solar photovoltaic panel 300.

[0073] Figure 5 An example is a schematic diagram of the physical structure of an electronic device, such as... Figure 5 As shown, the electronic device may include a processor 810, a communications interface 820, a memory 830, and a communication bus 840, wherein the processor 810, communications interface 820, and memory 830 communicate with each other via the communication bus 840. The processor 810 can call logic instructions in the memory 830 to execute a control method for the air conditioner, the method including: controlling the heating module to turn on to heat the base plate when the outdoor ambient temperature is lower than a first temperature threshold.
