Description

Technical Field

[0001] The present invention relates to the technical field of air conditioner outdoor cabinets, and particularly relates to a foldable photovoltaic air conditioner outdoor cabinet and a power supply system. Background Art

[0002] A solar air conditioner is an air conditioning system that uses solar energy as a power source or part of the power source. It converts the energy of sunlight into electrical energy or heat energy to drive the operation of the air conditioning system, thereby achieving the purpose of refrigeration or heating. It combines renewable energy technology and high-efficiency energy-saving technology, aiming to reduce the dependence on traditional fossil fuels, lower energy consumption and environmental impact. There are usually two main types of solar air conditioners: solar photovoltaic power generation air conditioners and solar thermal drive air conditioners. Solar photovoltaic power generation air conditioners use solar photovoltaic panels to directly convert sunlight into electrical energy, and then this electricity can be used to operate traditional electric air conditioning equipment. When the generated electricity exceeds the demand of the air conditioner, the excess electricity can also be stored for later use or fed back into the grid.

[0003] Solar photovoltaic power generation air conditioners need to collect solar energy with the help of photovoltaic panels. The air conditioner mainly includes an indoor unit and an outdoor unit. Since the air conditioner outdoor unit is exposed to the outdoors for a long time, the photovoltaic panels are all installed on the outdoor unit. Although the existing solar photovoltaic air conditioners can meet the basic usage requirements, their drawbacks are also very obvious. They are mainly manifested in that: in the prior art, the photovoltaic panels of photovoltaic air conditioners are installed through simple brackets and are exposed outside regardless of whether there is sunlight or other harsh environments, resulting in a short service life and high maintenance costs; and the photovoltaic panels cannot adaptively adjust their tilt angles according to the angle of sunlight, resulting in low utilization of solar energy; moreover, the area of the air conditioner outdoor cabinet is limited, which limits the installation area of the photovoltaic panels and prevents more photovoltaic panels from being installed to improve the utilization effect of solar energy.

[0004] In addition, in the existing solar air conditioner power supply system, due to the influence of the external environment on the solar air conditioner, the power generation of its solar panels is unstable, and users cannot accurately know the expected power generation of the solar panels and cannot intelligently switch the power supply mode of the air conditioner, resulting in the solar air conditioner being unable to meet the needs of users in some environments. Summary of the Invention

[0005] In view of the above-mentioned defects and problems, the present invention provides a foldable photovoltaic air conditioner outdoor unit chassis and a power supply system. By installing multiple photovoltaic panels on the chassis and designing the photovoltaic panels into a foldable structure, the area for installing photovoltaic panels on the chassis is increased, and the photovoltaic panels can also automatically adjust the angle according to the sun's rays, further improving the power generation of the photovoltaic panels. The electricity generated by the photovoltaic panels is stored in the storage battery. Combining with the power distribution control module and the power monitoring module, it can provide power supply modes of mains power supply, photovoltaic power supply, and hybrid power supply of photovoltaic power and mains power for the indoor unit of the photovoltaic air conditioner, the outdoor unit of the air conditioner, and other electrical appliances, and can intelligently switch the power supply mode according to the actual power generation of the photovoltaic panels, the operation of the air conditioner, and the user's needs.

[0016] Further, power-off electromagnetic locks are installed on the top of the detachable frame and the top of the upper frame beams on the left and right sides of the fixed frame, and a locking part matching with the power-off electromagnetic lock is arranged on the top of the movable end of the second photovoltaic panel. The second photovoltaic panel can be locked by the power-off electromagnetic lock.

[0017] Furthermore, the edge of the photovoltaic panel 2 is wrapped with a rubber frame, a groove is provided on the outside of the frame beam of the chassis frame assembly, and the shape of the rubber frame matches the groove. When the photovoltaic panel 2 is folded and retracted, the rubber frame is located in the groove.

[0018] To achieve the above-mentioned purpose, the present invention also provides a photovoltaic air-conditioning power supply system, including a crystalline silicon photovoltaic panel module, a junction box, an inverter, a battery, a transformer, and a distribution cabinet, wherein the distribution cabinet includes a photovoltaic power input terminal, a mains power input terminal, a distribution control module, a power monitoring module, and several output terminals.

[0019] Furthermore, the electrical equipment in the above photovoltaic air-conditioning power supply system are all located indoors.

[0020] Furthermore, the current output end of the crystalline silicon photovoltaic panel module is electrically connected to the input end of the combiner box through a wire, the output end of the combiner box is electrically connected to the current input end of the inverter, the current output end of the inverter is electrically connected to the current input end of the battery, the current output end of the battery is electrically connected to the current input end of the transformer, the current output end of the transformer is electrically connected to the photovoltaic power input end of the distribution cabinet, and the AC input end is electrically connected to the AC input end of the distribution cabinet.

[0021] Furthermore, the combiner box collects the current generated by multiple photovoltaic panels in the crystalline silicon photovoltaic panel module and transmits it to the inverter. The inverter converts the direct current generated by the crystalline silicon photovoltaic panel module into alternating current and stores it in the battery. The battery is equipped with a power monitoring module to monitor the battery's power, voltage, and current in real time, and provide the battery's power and output power to the power distribution control module. The transformer increases the voltage output by the battery to a voltage suitable for the normal operation of the electrical equipment.

[0022] Furthermore, the photovoltaic power input terminal and the mains power input terminal are electrically connected to the power distribution control module respectively, the power distribution control module is electrically connected to the power monitoring module, and the power monitoring module is electrically connected to output terminals No. 1 to No. 10 of the power distribution cabinet.

[0023] Furthermore, output terminal No. 1 is electrically connected to the sunlight sensor, output terminal No. 2 is electrically connected to the photovoltaic control module, output terminal No. 3 is electrically connected to the power-off electromagnetic lock, output terminal No. 4 is electrically connected to rotary motor 1, output terminal No. 5 is electrically connected to rotary motor 2, output terminal No. 6 is electrically connected to electric push rod 1, output terminal No. 7 is electrically connected to electric push rod 2, output terminal No. 8 is electrically connected to the indoor motor of the air conditioner, output terminal No. 9 is electrically connected to the outdoor motor of the air conditioner, and output terminal No. 10 is provided with multiple two-hole and three-hole interfaces, which can supply power to some household appliances, such as: desk lamps, monitors, electric fans, water purifiers, washing machines, refrigerators, air purifiers, etc.

[0024] Furthermore, the power distribution cabinet is equipped with a display screen and indicator lights. The content displayed on the display screen includes the current power of the battery, the photovoltaic charging power, the output power of each output terminal, and the power supply switching buttons for each output terminal. Users can manually select the power supply mode for each output terminal through the power supply switching buttons: photovoltaic power supply or mains power supply.

[0025] Furthermore, the power distribution control module can intelligently switch the power supply mode according to the actual power generation of the photovoltaic panels, the power and output power of the battery, the operation of the air conditioner, and user needs. When the photovoltaic air conditioner is installed and turned on for the first time, the power distribution control module reads the power and output power of the battery measured by the battery power monitoring module, and combines the operating states of the electrical appliances at each output terminal to determine whether the output power of the battery meets the rated power of the electrical equipment at each output terminal. If it meets, the battery is used for power supply; if not, the mains power is used for power supply.

[0026] Furthermore, when the air conditioner is turned on and running, the crystalline silicon photovoltaic panel module unfolds to receive sunlight for power generation, and the electric energy is stored in the battery through the busbar box and inverter. The power distribution control module compares the working power of the electrical appliances at each output terminal monitored by the power monitoring module with the output power of the battery. If the output power of the battery is lower than the working power of all electrical appliances at the output terminals, the power distribution control module uses the mains power to supply power to all electrical appliances.

[0027] Furthermore, as the power generation time of the crystalline silicon photovoltaic panel module increases, the power stored in the battery increases, and the output power of the battery increases. The power distribution control module can use the photovoltaic power stored in the battery to supply power to the electrical appliances at each output terminal. The power supply logic is as follows:

[0028] ① When the detected power of the battery is below 20%, the mains power is used to supply power to the electrical appliances at all output terminals.

[0029] ② When the detected power of the battery reaches 20% or more, and the output power of the battery meets the working power of any one of the electrical appliances such as the solar light sensor, photovoltaic control module, power-off electromagnetic lock, rotary motor 1, rotary motor 2, electric push rod 1, and electric push rod 2, the power distribution control module uses the photovoltaic power stored in the battery to supply power to the electrical appliance at this output terminal. As the crystalline silicon photovoltaic panel module continues to generate power, the output power of the battery gradually increases and will gradually meet the working power of the electrical appliances at the 1st to 7th output terminals. If it meets, the power distribution control module switches this output terminal to photovoltaic power supply.

[0030] ③ When the detected power of the battery reaches 60% or more, and the output power of the battery meets the working power of the indoor unit of the air conditioner, the power distribution control module switches the 8th output terminal to photovoltaic power supply.

[0031] ④ When it is detected that the battery power reaches over 90% and the output power of the battery can meet the working power of the outdoor unit of the air conditioner, the power distribution control module switches the 9th and 10th output terminals to photovoltaic power supply.

[0032] Furthermore, the present invention also provides a working mode - photovoltaic power generation mode. When this mode is started, the air conditioner does not operate. The crystalline silicon photovoltaic panel module will unfold to receive sunlight for power generation. The photovoltaic control module identifies the sunlight irradiation direction and angle according to the sunlight sensor, and adjusts the direction and inclination angle of the second photovoltaic panel in real time, and adjusts the flipping angle of the third photovoltaic panel to ensure the maximum power generation efficiency of the crystalline silicon photovoltaic panel module, and then quickly charges the battery.

[0033] Furthermore, in the above mode, when the battery power is lower than 30%, the power distribution control module switches the 10th output terminal to mains power supply. When the battery power ≥ 30%, the power distribution control module switches the 10th output terminal to photovoltaic power supply. At this time, the battery is in a state of charging through the crystalline silicon photovoltaic panel module while supplying power to household appliances through the 10th output terminal. When the battery power reaches 100%, the indicator light on the power distribution cabinet turns green, reminding the user to use the photovoltaic power in the battery to supply power to some household appliances through the 10th output terminal of the power distribution cabinet. Turn off the photovoltaic power generation mode, and the crystalline silicon photovoltaic panel module folds back.

[0034] Furthermore, the backplane on the back of the second photovoltaic panel is a fiberglass board, or a carbon fiber board, or a basalt fiber board, and a sunscreen and heat insulation coating is sprayed on the surface. When the air conditioner is turned off and the photovoltaic panel is rotated upward and folded, the backplane can play a good heat insulation role. Especially in extreme weather such as hail, the fiber board on the back can effectively resist the impact of hail and protect the photovoltaic panel.

[0035] Advantages of the present invention: By providing a chassis frame group, a crystalline silicon photovoltaic panel module, a flipping drive mechanism, and an angle adjustment mechanism, multiple photovoltaic panels can be directly fixed or movably installed on the chassis frame group. The design of the chassis frame group allows multiple photovoltaic panels to be installed in a limited space, increasing the installation area of the photovoltaic panels and improving the utilization effect of solar energy. And through the foldable design, the movable photovoltaic panels can be controlled to unfold by the flipping drive mechanism during the operation of the air conditioner, and then each photovoltaic panel is exposed to receive sunlight. Moreover, through the cooperation of the electric push rod and the angle adjustment mechanism, the photovoltaic panels can automatically adjust the angle and position according to the angle of the sunlight to follow the sun's azimuth, ensuring that each photovoltaic panel can receive sunlight, capturing more sunlight, and guaranteeing the power generation efficiency of the photovoltaic panels. When the air conditioner stops running, the photovoltaic panels can be flipped or moved back to coincide with the photovoltaic panels of the chassis frame group, realizing the folding and protection functions, reducing the damage to the photovoltaic panels caused by bad weather conditions, extending the service life of the photovoltaic panels, and reducing the maintenance cost. At the same time, the present invention provides a power supply system, which can provide photovoltaic power supply, mains power supply, and hybrid photovoltaic and mains power supply modes for the air conditioner and other electrical equipment through the power supply control module, and can intelligently switch the power supply mode according to the actual power generation situation of the photovoltaic panels, the operation situation of the air conditioner, and the user's needs, greatly reducing the use of mains power by the air conditioner and other electrical facilities, and achieving the purpose of energy conservation and emission reduction.

[0050] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0051] Please refer to Figures 1-13 , the present invention provides a technical solution for a foldable chassis and power supply system of an outdoor unit of a photovoltaic air conditioner:

[0052] Embodiment 1: According to Figures 1-3As shown in the figure, it includes an outdoor air conditioner 1 and a chassis frame group 2. The outdoor air conditioner 1 is arranged inside the chassis frame group 2. The chassis frame group 2 includes a detachable frame 21 and a fixed frame 22. The detachable frame 21 is a rectangular frame. Bolt holes are provided at the four corners of the fixed frame 22 and the detachable frame 21. The detachable frame 21 can be installed on the front side of the fixed frame 22 through bolts. After the detachable frame 21 and the fixed frame 22 are installed, they form a thin-walled light steel frame chassis frame group 2 in the shape of a cube. The thin-walled light steel frame chassis frame group 2 serves as the support frame for the outdoor body of the air conditioner. The frame beam of the chassis frame group 2 has an L-shaped cross-section and is provided with a card slot 2b that can accommodate and clamp the fixed outdoor air conditioner 1. A crystalline silicon photovoltaic panel module 3 is installed on the chassis frame group 2. The crystalline silicon photovoltaic panel module 3 includes multiple photovoltaic panels. Photovoltaic panels 31 are fixedly installed on the left and right sides of the fixed frame 22 and the detachable frame 21. A hole corresponding to the position and size of the exhaust fan of the outdoor air conditioner 1 is provided on the surface of the photovoltaic panel 31, and a metal protection net is built-in. Photovoltaic panels 32 are rotatably connected to the lower ends of the left and right sides of the fixed frame 22 and the lower end of the detachable frame 21. The photovoltaic panels 32 can be controlled by a flipping drive mechanism 6 to flip downward and open. When the photovoltaic panels 32 flip downward, both the photovoltaic panels 31 and the photovoltaic panels 32 can be exposed to the outside. Frame support plates 24 are welded and fixed on the upper and lower sides of the fixed frame 22. A photovoltaic panel 33 is installed above the upper frame support plate 24, and the photovoltaic panel 33 can be controlled by an angle adjustment mechanism 7 to adjust the angle. A photovoltaic panel 34 is longitudinally slidably sleeved on the rear side of the fixed frame 22, and the photovoltaic panel 34 can be controlled by a driving member to slide up and down, moving from the rear of the outdoor air conditioner 1 to above, so that the photovoltaic panel 34 is exposed to the outside. By setting the crystalline silicon photovoltaic panel module 3 composed of multiple photovoltaic panels, after the crystalline silicon photovoltaic panel module 3 is installed on the chassis frame group, the photovoltaic panels 31, 32, 33, and 34 respectively form the front, left and right sides, top and back of the outdoor chassis of the air conditioner, forming a complete shell of the outdoor chassis of the air conditioner, which not only plays the role of protecting the internal electrical facilities of the outdoor chassis of the air conditioner, but also can be used as a power generation device. And when the air conditioner is in operation, the movable photovoltaic panels can be flipped or moved to unfold, ensuring that each photovoltaic panel can receive sunlight, thereby improving the utilization rate of sunlight. When the air conditioner stops running, the photovoltaic panels are flipped or moved back to coincide with the photovoltaic panel 31 in front of the chassis frame group 2, realizing the folding and protection functions.

[0053] The backplane on the back of the photovoltaic panel 32 is a fiberglass board, or a carbon fiber board, or a basalt fiber board, and a sunscreen and heat insulation coating is sprayed on the surface. When the air conditioner is turned off and the photovoltaic panel is rotated and folded upward, the backplane on the back will be irradiated by the sun for a long time. The backplane on the back plays a protective role for the photovoltaic panel. Especially in extreme weather such as hail, the fiber board on the back can effectively resist the impact of hail and protect the photovoltaic panel.

[0054] According to Figure 4 、Figure 5 and Figure 9 As shown, shaft seats 4 are symmetrically arranged on the lower frame beams on the left and right sides of the detachable frame 21 and the fixed frame 22. A rotating shaft 5 parallel to the frame beam is rotatably installed in the shaft seat 4. The lower end of the second photovoltaic panel 32 is fixedly sleeved on the rotating shaft 5, and the upper end is movable. The second photovoltaic panel 32 can be flipped outwards or inwards through the rotating shaft 5 to a state parallel to the chassis frame group 2. A flipping drive mechanism 6 is arranged on the chassis frame group 2, and the flipping drive mechanism 6 can drive the second photovoltaic panel 32 to flip.

[0055] According to Figure 5 and Figure 8 As shown, the flipping drive mechanism 6 includes a mounting plate 65 installed at the top connection of the detachable frame 21 and the fixed frame 22. The mounting plate 65, the detachable frame 21 and the fixed frame 22 are provided with bolt holes corresponding in position. The mounting plate 65 can be installed on the detachable frame 21 and the fixed frame 22 by bolts, and the mounting plate 65 can also improve the connection effect at the connection of the detachable frame 21 and the fixed frame 22. At both ends of the lower frame beam of the detachable frame 21, supports are welded and fixed. On the left and right sides of the detachable frame 21, screw rods 61 are longitudinally rotatably sleeved through the mounting plate 65 and the supports. The screw rods 61 are arranged at the corners of the chassis frame group 2 and are parallel to the longitudinal frame beam, which does not interfere with the flipping movement of the second photovoltaic panel 32. And a drive unit for controlling the rotation of the screw rod 61 is arranged on the mounting plate 65. A nut 63 is rotatably sleeved on the screw rod 61, and a pulley 64 is fixed on the nut 63. The flipping drive mechanism 6 further includes a flipping pull rope 68. The front end of the flipping pull rope 68 is connected to the side of the second photovoltaic panel 32, and after being guided by the pulley 64, the rear end is fixedly connected to the nearest shaft seat 4. When the screw rod 61 rotates to control the up and down movement of the nut 63, the flipping pull rope 68 can be pulled to move through the pulley 64, and then the second photovoltaic panel 32 can be pulled to flip around the rotating shaft 5 through the flipping pull rope 68. Guide rails 610 are provided on the left and right longitudinal frame beams of the detachable frame 21. A guide block 69 is fixed on the side of the nut 63, and the guide block 69 is slidably sleeved in the guide rail 610. Through the cooperation of the guide block 69 and the guide rail 610, the movement of the nut 63 is limited and guided to ensure the up and down movement of the nut 63.

[0056] Two pulleys 64 are installed on one nut 63 and two flipping pull ropes 68 are provided. One flipping pull rope 68 is connected to the second photovoltaic panel 32 on the left or right side of the fixed frame 22, and the other flipping pull rope 68 is connected to the second photovoltaic panel 32 on the left or right side of the detachable frame 21. In this way, the second photovoltaic panels 32 on the detachable frame 21 and the fixed frame 22 can be simultaneously pulled and flipped by the flipping pull ropes 68, realizing the synchronous flipping movement of the second photovoltaic panel 32.

[0057] The driving unit includes a first rotating motor 66 mounted on the mounting plate 65. A driving gear 67 is fixedly sleeved on the output end of the first rotating motor 66. And a driven gear 62 meshing with the driving gear 67 is fixedly sleeved on the top of the screw 61. The first rotating motor 66 drives the driving gear 67 to rotate. Under the meshing force of the driving gear 67 and the driven gear 62, the screw 61 can be driven to rotate. Furthermore, in cooperation with the thread effect of the nut 63, the turning pull rope 68 is pulled to realize the turning of the second photovoltaic panel 32.

[0058] According to Figure 6 As shown, chutes are provided on the rear longitudinal beam of the fixed frame 22. Sliding strips matching the chutes are provided on the left and right front sides of the fourth photovoltaic panel 34. The fourth photovoltaic panel 34 is longitudinally slidably sleeved in the chutes through the sliding strips. And fixing platforms are installed on the lower frame beam at the rear of the fixed frame 22 and on the rear side of the fourth photovoltaic panel 34. Electric push rods II 8 are installed on the fixing platforms. A back plate frame 23 is also welded at the rear of the fixed frame 22. The back plate frame 23 encloses the fourth photovoltaic panel 34 and the electric push rods II 8 in the chassis frame group 2. The fourth photovoltaic panel 34 can be driven to move up and down by the electric push rods II 8, and free telescoping in the vertical direction can be realized. When shutting down, the electric push rods II 8 contract, and the fourth photovoltaic panel 34 is stored inside the chassis frame group 2 to play a protective role. When working, the electric push rods II 8 extend, and the fourth photovoltaic panel 34 extends out of the chassis frame group 2 to capture sunlight for power generation.

[0059] The third photovoltaic panel 33 is installed above the chassis frame group 2 through an angle adjustment mechanism 7. The angle adjustment mechanism 7 includes a turntable 71 rotatably sleeved on the upper frame support plate 24 through a transmission shaft. A support plate 73 is fixed above the turntable 71. The third photovoltaic panel 33 is hinged above the support plate 73. The front end of the third photovoltaic panel 33 is hinged on the support plate 73, and the rear end can be controlled to move through the first electric push rod 77 to realize the angle adjustment of the third photovoltaic panel 33. A slider 76 is slidably sleeved on the rear wall of the third photovoltaic panel 33. The lower end of the first electric push rod 77 is fixed on the support plate 73, and the upper end is hinged to the rear of the third photovoltaic panel 33 through the slider 76. The telescoping of the first electric push rod 77 can realize the adjustment of the inclination amplitude of the third photovoltaic panel 33. A second rotating motor 74 is also installed on the frame support plate 24. A driving gear 75 is fixedly sleeved on the output end of the second rotating motor 74. And a toothed ring 72 is provided on the periphery of the turntable 71. The driving gear 75 meshes with the toothed ring 72. By driving the driving gear 75 to rotate through the second rotating motor 74, under the meshing force of the driving gear 75 and the toothed ring 72, the turntable 71 and the third photovoltaic panel 33 can be driven to rotate slowly to realize the adjustment of the left and right angles of the third photovoltaic panel 33, enabling the third photovoltaic panel 33 to rotate following the sun's azimuth in the horizontal direction to capture more sunlight.

[0060] A rubber frame 3a is wrapped around the edge of the second photovoltaic panel 32. The rubber frame 3a is light in weight, which can reduce the weight of the suspended photovoltaic panel below and protect the edge of the photovoltaic panel to prevent damage to the edge of the photovoltaic panel. A groove 2a is provided on the outer side of the frame beam of the chassis frame group 2, and the shape of the rubber frame 3a fits the groove 2a on the outer surface of the steel frame of the chassis frame group 2. When the suspended second photovoltaic panel 32 below is folded and retracted, the rubber frame 3a can be located at the groove 2a on the outer surface of the steel frame of the chassis frame group 2, achieving the sealing effect of the chassis frame group 2.

[0061] During specific use, for a foldable photovoltaic air conditioner outdoor unit chassis of the present invention, first, each crystalline silicon photovoltaic panel module 3 is installed on the chassis frame group 2, and the air conditioner outdoor unit 1 is placed and fixed inside the chassis frame group 2, and then the chassis frame group 2 is suspended and fixed outdoors. When the air conditioner is operating, the first rotating motor 66 drives the driving gear 67 to rotate forward. Under the meshing force of the driving gear 67 and the driven gear 62, the screw rod 61 is driven to rotate. Under the thread matching effect of the screw rod 61 and the nut 63, the nut 63 is driven to move downward, and the second photovoltaic panel 32 rotates downward around the rotating shaft 5. At the same time, the second photovoltaic panel 32 is pulled by the flipping pull rope 68 to ensure the smooth flipping of the second photovoltaic panel 32 and control the flipping angle of the second photovoltaic panel 32, exposing both the first photovoltaic panel 31 and the second photovoltaic panel 32; at the same time, the second electric push rod 8 extends, moving the fourth photovoltaic panel 34 upward from the rear of the chassis frame group 2 to expose it; and the second rotating motor 74 drives the gear 75 to rotate. Under the meshing force of the driving gear 75 and the gear ring 72, the turntable 71 and the third photovoltaic panel 33 are driven to rotate slowly to adjust the horizontal angle of the third photovoltaic panel 33. At the same time, the first electric push rod 77 extends to adjust the tilt angle of the third photovoltaic panel 33 so that the third photovoltaic panel 33 corresponds to the sun's orientation. At this time, all the photovoltaic panels are exposed to the outside to collect sunlight, achieving the efficient utilization of solar energy.

[0062] After the air conditioner stops running, the first rotating motor 66 drives the driving gear 67 to rotate in the reverse direction, driving the screw rod 61 to rotate, and then controlling the nut 63 to move upward. The second photovoltaic panel 32 is pulled upward and retracted by the flipping pull rope 68, causing the second photovoltaic panel 32 to overlap with the first photovoltaic panel 31. At the same time, the second electric push rod 8 contracts to drive the fourth photovoltaic panel 34 to retract into the chassis frame group 2, achieving the enclosure of the chassis frame group 2.

[0063] Embodiment 2: On the basis of Embodiment 1, as Figure 1 and Figure 2As shown in the figure, power-off electromagnetic locks 10 are installed on the top of the upper frame beams on the left and right sides of the detachable frame 21 and the fixed frame 22, and a locking part matching the power-off electromagnetic lock 10 is provided at the top of the movable end of the second photovoltaic panel 32. When the air conditioner stops running and the second photovoltaic panel 32 is flipped and retracted, the power-off electromagnetic lock 10 will be activated and lock the movable end of the second photovoltaic panel 32 through the locking part, thereby limiting and fixing the top of the second photovoltaic panel 32, and further improving the stability of the second photovoltaic panel 32 after retraction.

[0064] Embodiment 3: On the basis of Embodiment 1, as Figure 2 shown in the figure, sunlight sensors 9 can be installed on the first photovoltaic panel 31 and the third photovoltaic panel 33. Through the sunlight sensors 9, the sunlight irradiation direction and angle can be identified, and then the inclination angle and horizontal rotation angle of the second photovoltaic panel 32 and the fourth photovoltaic panel 34 can be determined, so that the second photovoltaic panel 32 and the third photovoltaic panel 33 can follow the sunlight, and the utilization effect of solar energy can be further improved. The sunlight sensor 9 can identify the sunlight irradiation direction and angle, and then determine the inclination angle and horizontal rotation angle of this photovoltaic panel.

[0065] A photovoltaic control module 11 is provided on the frame support plate 24 above the chassis fixed frame 22. The photovoltaic control module 11 controls the rotation of the first rotation motor 66 and adjusts the orientation of the second photovoltaic panel 32 according to the sunlight irradiation direction and angle identified by the sunlight sensor 9, and controls the telescopic movement of the first electric push rod 77 to adjust the angle of the second photovoltaic panel 32, ensuring a higher power generation efficiency of the second photovoltaic panel 32.

[0066] Embodiment 4: This embodiment provides a method for electrically connecting a photovoltaic air conditioner and a power supply method for a power supply system

[0067] As Figures 10-13 shown in the figure, the current output end of the crystalline silicon photovoltaic panel module 3 is electrically connected to the input end of the busbar box 12 through a wire, the output end of the busbar box 12 is electrically connected to the current input end of the inverter 13, the current output end of the inverter 13 is electrically connected to the current input end of the storage battery 14, the current output end of the storage battery 14 is electrically connected to the current input end of the transformer 15, the current output end of the transformer 15 is electrically connected to the photovoltaic power input end of the power distribution cabinet 16, and the commercial power is electrically connected to the commercial power input end of the power distribution cabinet.

[0068] The busbar box 12 and the inverter 13 are located inside the photovoltaic air conditioner outdoor unit, and the storage battery 14 and the transformer 15 are located indoors. The busbar box 12 collects the currents generated by multiple photovoltaic panels in the crystalline silicon photovoltaic panel module 3 together for centralized management and transmission. Since both household and commercial electricity are alternating current, the inverter 13 can convert the direct current generated by the crystalline silicon photovoltaic panel module 3 into alternating current. The storage battery 14 stores the electric energy generated by the crystalline silicon photovoltaic panel module 3, and is internally provided with a power monitoring module to monitor the power, voltage, and current of the storage battery in real time, and provide the real-time output power of the storage battery to the power distribution control module. Then the transformer 15 boosts the voltage output by the storage battery 14 to a voltage suitable for the normal operation of electrical equipment. All the electrical equipment in the above photovoltaic air conditioner power supply system is located indoors.

[0069] The connection method of the power distribution cabinet 16 with each electrical component is as follows: The No. 1 output terminal is electrically connected to the sunlight sensor 9, the No. 2 output terminal is electrically connected to the photovoltaic control module 11, the No. 3 output terminal is electrically connected to the power-off electromagnetic lock 10, the No. 4 output terminal is electrically connected to the first rotary motor 66, the No. 5 output terminal is electrically connected to the second rotary motor 74, the No. 6 output terminal is electrically connected to the first electric push rod 77, the No. 7 output terminal is electrically connected to the second electric push rod 8, the No. 8 output terminal is electrically connected to the air conditioner indoor unit 17, the No. 9 output terminal is electrically connected to the air conditioner outdoor unit 1, and the No. 10 output terminal is provided with a plurality of two-hole and three-hole interfaces for supplying power to some household appliances 18, such as: table lamps, monitors, electric fans, water purifiers, washing machines, refrigerators, air purifiers, etc.

[0070] Moreover, the power distribution cabinet 16 is provided with a display screen and indicator lights. The display screen will display the current power of the storage battery 14, the photovoltaic charging power, the output power of each output terminal, and the power supply switching buttons of each output terminal. Users can manually select the power supply mode of each output terminal through the power supply switching buttons: photovoltaic power or mains power.

[0071] The input end of the power distribution cabinet 16 is divided into a photovoltaic input end and a mains input end. The power distribution cabinet is internally provided with a power distribution control module and a power monitoring module, and the power monitoring module can monitor the power of each electrical appliance in real time. When the photovoltaic air conditioner is installed and the air conditioner is turned on for the first time, the power distribution control module reads the output power that the storage battery 14 can output monitored by the storage battery power monitoring module, and judges whether the output power of this storage battery 14 meets the rated power of each output terminal of the power distribution cabinet. If it meets, the storage battery is used for power supply. If it does not meet, the mains power is used for power supply.

[0072] When the air conditioner is turned on and running, the crystalline silicon photovoltaic panel module 3 unfolds to receive sunlight for power generation and stores the generated electricity in the storage battery. The power distribution control module, in combination with the power monitoring module, detects the working power of the electrical appliances at each output terminal and compares it with the output power that the storage battery 14 can provide. If the output power that the storage battery 14 can provide is lower than the working power of the electrical appliances at all output terminals, the power distribution control module uses the commercial power to supply power to all output terminals. As the power generation time of the crystalline silicon photovoltaic panel module increases, the more electricity is stored in the storage battery 14, and the output power that the storage battery 14 can provide continuously increases. The power distribution control module can use the photovoltaic power stored in the storage battery 14 to supply power to the electrical appliances at each output terminal. The power supply logic is as follows:

[0073] ① When it is detected that the power level of the storage battery is below 20%, the commercial power is used to supply power to the electrical appliances at all output terminals;

[0074] ② When it is detected that the power level of the storage battery reaches above 20% and the output power that the storage battery can provide meets the working power of any one of the electrical appliances such as the sunlight sensor 9, the photovoltaic control module 11, the power-off electromagnetic lock 10, the rotary motor one 66, the rotary motor two 74, the electric push rod one 77, and the electric push rod two 8, the power distribution control module uses the photovoltaic power stored in the storage battery 14 to supply power to the electrical appliance at this output terminal. As the crystalline silicon photovoltaic panel module 3 continues to generate power, the output power that the storage battery 14 can provide gradually increases and will gradually meet the working power of the electrical appliances at the No. 1 - No. 7 output terminals. If it meets the requirement, the power distribution control module switches this output terminal to photovoltaic power supply;

[0075] ③ When it is detected that the power level of the storage battery reaches above 60% and the output power that the storage battery can provide meets the working power of the indoor unit of the air conditioner, the power distribution control module switches the No. 8 output terminal to photovoltaic power supply;

[0076] ④ When it is detected that the power level of the storage battery reaches above 90% and the output power that the storage battery can provide meets the working power of the outdoor unit of the air conditioner, the power distribution control module switches the No. 9 and No. 10 output terminals to photovoltaic power supply.

[0077] In addition, the photovoltaic air conditioner has another working mode - the photovoltaic power generation mode. When the air conditioner does not need to operate and only the crystalline silicon photovoltaic panel module 3 needs to generate electricity, this mode is started. The crystalline silicon photovoltaic panel module 3 is unfolded to receive sunlight for power generation, and the storage battery 14 is charged. When the power of the storage battery 14 is lower than 30%, the power distribution control module switches the 10th output terminal to mains power supply; when the power of the storage battery 14 is ≥ 30%, the power distribution control module switches the 10th output terminal to photovoltaic power supply. At this time, the storage battery 14 is in a situation where it is charging through the crystalline silicon photovoltaic panel module 3 while supplying power to the household appliances 18 through the 10th output terminal; when the power of the storage battery 14 reaches 100%, the crystalline silicon photovoltaic panel module 3 is folded and retracted, and at the same time, the indicator light on the power distribution cabinet turns green, reminding the user to use the photovoltaic power in the storage battery to supply power to some household appliances through the 10th output terminal of the power distribution cabinet.

[0078] The above are only the preferred embodiments of the present invention, which do not limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
