DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0036] Embodiment 1

[0037] like Figure 1-Figure 12 As shown, a purification and energy-saving engineering system proposed in one embodiment of the present application includes an air-conditioning outdoor unit 1, an air-conditioning body 6, and a condenser 2 installed in the air-conditioning outdoor unit 1, the condenser 2 is connected to the air-conditioning body 6, and a water outlet pipe 7 is installed on the air-conditioning body 6, and also includes:

[0038] The cooling mechanism 3 includes a mounting frame 301 mounted on the air conditioner outdoor unit 1, a cooling fan 302 is mounted in the mounting frame 301, a water storage tank 303 is mounted on the outside of the air conditioner outdoor unit 1, a spray assembly 304 is movably mounted inside the air conditioner outdoor unit 1, a drainage plate 306 located below the condenser 2 is constructed on the air conditioner outdoor unit 1, and a drainage pipe 305 is connected to one side of the air conditioner outdoor unit 1;

[0039] The water supply mechanism 4 is installed on the water storage tank 303 and acts on the spray assembly 304 and the water storage tank 303, and is used to transport the water in the water storage tank 303 to the spray assembly 304;

[0040] The driving mechanism 5 is installed on the air conditioner outdoor unit 1 and acts on the spray assembly 304. The driving mechanism 5 is used to drive the spray assembly 304 to move. That is, when the air conditioner body 6 is in use, the temperature around the condenser 2 in the air conditioner outdoor unit 1 increases. At this time, the cooling fan 302 continues to rotate, and at this time, the water in the water storage tank 303 is pumped into the spray assembly 304 through the water supply mechanism 4, thereby providing a water source to the spray assembly 304, so that the spray assembly 304 pumps the water in the water storage tank 303 into the cooling pipe of the condenser 2. , and in the process of spraying by the spray component 304, the spray component 304 can be moved by the driving mechanism 5, so that water can be fully sprayed on the surface of the condenser 2, and the heat dissipation effect is improved by cooperating with the heat dissipation fan 302. After the water covering the condenser 2 absorbs heat, it will drip onto the upper drainage plate 306 due to the action of gravity, and then be discharged to the outside from the drain pipe 305, reducing the load of the compressor in the air-conditioning outdoor unit 1, thereby achieving the effect of energy saving, improving the heat dissipation effect of the condenser 2, and indirectly reducing energy consumption.

[0041] Embodiment 2

[0042] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this embodiment further improves the present application on the basis of the first embodiment, the spray assembly 304 includes a movable frame 3041 vertically slidably mounted on the air-conditioning outdoor unit 1, a connecting box 3043 is horizontally slidably mounted on the movable frame 3041, an atomizing nozzle 3042 is mounted on the connecting box 3043, a driving mechanism 5 acts on the movable frame 3041, and a connecting member 8 acting on the connecting box 3043 is mounted on the air-conditioning outdoor unit 1, when the movable frame 3041 moves, the connecting box 3043 is moved by the connecting member 8, that is, the vertical movement of the movable frame 3041 is realized by the driving mechanism 5 to realize the vertical movement of the connecting box 3043, and in the process of the vertical movement of the movable frame 3041, the connecting box 3043 is moved horizontally by the connecting member 8, thereby further improving the spraying range of the atomizing nozzle 3042 and further improving the heat dissipation effect.

[0043] like Figure 3-Figure 6 As shown, in some embodiments, the linkage 8 includes a wave groove 801 vertically opened on the air-conditioning outdoor unit 1, and the connecting box 3043 is constructed with a column rod 802 that slides tangentially in the wave groove 801. That is to say, when the movable frame 3041 moves vertically, because the column rod 802 on the connecting box 3043 slides tangentially in the wave groove 801, when the movable frame 3041 moves vertically, the connecting box 3043 is indirectly driven to reciprocate horizontally through the cooperation of the column rod 802 and the wave groove 801, thereby driving the connecting box 3043 to move horizontally without the need for additional driving force.

[0044] like Figure 6-Figure 9 As shown, in some embodiments, the water supply mechanism 4 includes a water pumping cylinder 401 vertically installed in the water storage tank 303, a piston plate 402 is vertically slidably installed in the water pumping cylinder 401, a circular array is formed on the top of the piston plate 402 with a plurality of through holes 403, a connecting rod 404 is constructed on the top of the piston plate 402, a connecting frame 405 is constructed on the connecting rod 404, a plurality of blocking plates 406 for shielding the through holes 403 are vertically slidably installed on the connecting frame 405, and the blocking plates 406 are A return spring 409 is installed between the connecting frame 405, the blocking plate 406 is located above the piston plate 402, a water inlet groove 407 is provided on one side of the water storage tank 303 near the bottom of the water storage tank 303, a one-way delivery pipe 408 is connected between the water pump 401 and the connecting box 3043, and a transmission member 12 for driving the connecting rod 404 to move is installed on the air conditioner outdoor unit 1. When the connecting rod 404 moves downward through the transmission member 12, the connecting rod 404 moves downward to drive the piston plate 402 to move downward, and the air conditioner outdoor unit 1 is provided with a transmission member 12 for driving the connecting rod 404 to move downward. When the plug plate 402 moves downward, because the water storage tank 303 and the water pumping cylinder 401 are in a connected state, there is water in the water pumping cylinder 401 at this time. When the piston plate 402 moves downward, the blocking plate 406 will move upward due to the impact of the water flow, so that a gap is left between the blocking plate 406 and the piston plate 402, so that the water is located above the piston plate 402. When the connecting rod 404 moves upward, the upward movement of the connecting rod 404 will drive the piston plate 402 to move upward. At this time, the piston Because the return spring 409 of the plate 402 will block the perforation 403, when the piston plate 402 moves upward, the water above the piston plate 402 will be pumped into the one-way delivery pipe 408. Specifically, a one-way valve is installed in the one-way delivery pipe 408, so when the water is pumped into the one-way delivery pipe 408, it will not flow back into the water pump 401. Therefore, when the piston plate 402 moves back and forth vertically, the water in the water tank 303 will be pumped into the one-way delivery pipe 408, thereby causing the atomizing nozzle 3042 to spray water vapor.

[0045] like Figure 6-Figure 9 As shown, in some embodiments, a baffle 9 for shielding the water inlet groove 407 is horizontally slidably installed in the water pumping cylinder 401, and a rod body 10 is configured on the side of the baffle 9 away from the water inlet groove 407. A sleeve 11 is installed in the water pumping cylinder 401 and is sleeved on the rod body 10. A return spring 18 is installed between the rod body 10 and the sleeve 11. The top of the water pumping cylinder 401 passes through the water storage tank 303 and is located above the drainage plate 306. Figure 8As shown, when the piston plate 402 moves downward, the water in the water pumping cylinder 401 below the piston plate 402 will pass through the perforation 403 and be located above the piston plate 402 due to negative pressure, and the baffle plate 9 will block the water inlet groove 407 at this time. When the piston plate 402 moves upward, the negative pressure will cause the baffle plate 9 to move away from the water inlet groove 407. At this time, there is a gap between the baffle plate 9 and the water inlet groove 407, so the water in the water storage tank 303 will flow into the bottom end of the water pumping cylinder 401 and the bottom of the piston plate 402. The water above the piston plate 402 is squeezed into the one-way delivery pipe 408. When the piston plate 402 moves downward, the return spring 18 is reset and the baffle plate 9 blocks the water inlet groove 407. Similarly, the water in the pump cylinder 401 can be pumped into the one-way delivery pipe 408 even when the reciprocating stroke of the piston plate 402 is short. In addition, the water can be pumped into the one-way delivery pipe 408 even when the piston plate 402 is lower than the internal water level of the water tank 303 during the reciprocating movement of the piston plate 402.

[0046] like Figure 4 and Fig.10 As shown, in some embodiments, the driving mechanism 5 includes a synchronous wheel 501 installed on the air-conditioning outdoor unit 1 in a vertically rotatable manner, a synchronous belt 502 is synchronously installed between the two synchronous wheels 501, a motor for driving one of the synchronous wheels 501 to move is installed on the air-conditioning outdoor unit 1, a guide groove 503 is horizontally opened on the movable frame 3041, and one end surface of the synchronous belt 502 is constructed with a shaft rod 504 that slides and is tangent to the guide groove 503. That is to say, one of the synchronous wheels 501 is rotated by the continuous rotation of the motor, and then cooperates with the other synchronous wheel 501 to realize the continuous movement of the synchronous belt 502. The continuous movement of the synchronous belt 502 indirectly drives the shaft rod 504 to move. Because the shaft rod 504 slides and is tangent to the guide groove 503, when the synchronous belt 502 moves, the movable frame 3041 is forced to move back and forth vertically through the shaft rod 504, thereby realizing a large-scale reciprocating movement of the movable frame 3041. The overall structure is more compact, the layout is more reasonable, and the occupied space is reduced.

[0047] like Figure 8 and Fig.12 As shown, in some embodiments, the transmission member 12 acts on one of the synchronous wheels 501. When the synchronous wheel 501 rotates, the connecting rod 404 is moved through the transmission member 12. That is to say, when one of the synchronous wheels 501 rotates, the connecting rod 404 can be reciprocated through the transmission member 12, thereby ensuring the overall continuity. There is no need to control the movement of the connecting rod 404, which is more convenient to use.

[0048] Embodiment 3

[0049] like Figure 8 and Fig.12As shown, this embodiment further improves the present application on the basis of Embodiment 1 and Embodiment 2, the transmission member 12 includes a rotating wheel 1201 rotatably mounted on the air-conditioning outdoor unit 1, one end of the rotating wheel 1201 is eccentrically hinged with a connecting rod 1202, a hinged rod 1203 is hinged between the connecting rod 404 and the connecting rod 1202, the rotating wheel 1201 is coaxially connected to the synchronous wheel 501 located below, when the synchronous wheel 501 located below rotates, the rotating wheel 1201 connected to the rotating wheel 1201 will also rotate, and the connecting rod 1202 eccentrically hinged to the rotating wheel 1201 will also move, because the connecting rod 1202 and the connecting rod 404 are hinged with the hinged rod 1203, so as the rotating wheel 1201 continues to rotate, the connecting rod 404 will be driven to reciprocate vertically through the connecting rod 1202, so that no additional driving force is required to drive the connecting rod 404 to reciprocate vertically, which is more convenient to use.

[0050] like Figure 3 and Figure 5 As shown, in some embodiments, the free end of the water outlet pipe 7 is connected to the water tank 303, so that the water (commonly known as air-conditioning water) generated by the air-conditioning body 6 flows directly from the water outlet pipe 7 into the water tank 303, and is used to cool the condenser 2, thereby reducing the number of times the water is added to the water tank 303. One side of the water tank 303 is connected to a water inlet box 13 with an opening at the top, and a filter screen 14 is installed on the top of the water inlet box 13. When it rains, rainwater will pass through the filter screen 14 into the water inlet box 13, and then enter the water tank 303, thereby reducing the frequency of adding water to the water tank 303. The design of the filter screen 14 effectively prevents impurities from entering the water tank 303.

[0051] like Figure 5 and Figure 7 As shown, in some embodiments, a sliding plate 15 for covering the top of the filter screen 14 is horizontally slidably installed on the water tank 303, and a floating frame 16 is vertically slidably installed inside the water tank 303. A transmission rod 17 is hinged between the floating frame 16 and the sliding plate 15. In a rainy environment, when the water level in the water tank 303 rises, because the floating frame 16 floats in the water tank 303, the floating frame 16 will move upward at this time, thereby driving the sliding plate 15 to move toward the filter screen 14 through the transmission rod 17. At this time, impurities on the filter screen 14 will be pushed away by the sliding plate 15, thereby preventing the filter screen 14 from being blocked by excessive impurities, and when the water inside the water tank 303 reaches a certain height, the sliding plate 15 will block the filter screen 14, thereby preventing water from entering the water tank 303, thereby limiting the water level in the water tank 303.

[0052] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
