Description

Technical Field

[0001] The present disclosure belongs to the technical field of air conditioner outdoor unit cooling, and particularly relates to an energy-saving air conditioner outdoor unit cooling device. Background Art

[0002] Air conditioners have become ubiquitous in people's lives and industrial production. The larger the space, the better the required cooling effect, and the larger the volume of the air conditioner will be to meet the cooling requirements of the large space. Especially for air conditioners in production workshops or factories, the outdoor unit of the air conditioner is slightly larger and emits more heat. Cooling the outdoor unit of the air conditioner helps to improve the cooling effect of the air conditioner and its efficiency.

[0003] Currently, for cooling the outdoor unit of the air conditioner, a cooling fan is usually used to suck or blow away the heat on the condenser tube to achieve the purpose of cooling. However, when the outdoor unit of the air conditioner is large and the overall cooling demand of the air conditioner is greater, the effect of cooling the condenser tube by sucking or blowing away the heat with a cooling fan is not significant enough, and the temperature of the condenser tube and even the entire outdoor unit of the air conditioner is relatively high. Therefore, the cooling of high-power air conditioner outdoor units needs to be improved. Summary of the Invention

[0004] To solve the above problems, the present disclosure provides an energy-saving air conditioner outdoor unit cooling device. It absorbs heat by atomizing the condenser tube, collects and filters the water that has not evaporated after atomization, recycles it and atomizes it again. At the same time, it can automatically compensate the water to cool the condenser tube, and together with the cooling fan for auxiliary heat dissipation, so as to save water resources while recycling the used water to cool and dissipate heat from the outdoor unit of the air conditioner, thereby improving the heat dissipation effect on high-power air conditioner outdoor units.

[0005] The present disclosure provides an energy-saving air conditioner outdoor unit cooling device, including: a chassis, in which a condenser tube, a cooling fan and a compressor are provided; a spraying mechanism, including a first spraying rod and a second spraying rod arranged in the chassis, and nozzles facing the condenser tube are provided on the first spraying rod and the second spraying rod; a water supply mechanism, including a water supply tank and a water pump, and the water pump is used to supply the water in the water supply tank to the first spraying rod and the second spraying rod.

[0006] With such a setting, when the outdoor unit of the air conditioner is in normal use, the water pump pumps the water in the water supply tank into the first spraying rod and the second spraying rod, so that the nozzles on the first spraying rod and the second spraying rod spray water mist onto the condenser tube to cool the condenser tube. At the same time, the cooling fan also absorbs the heat on the condenser tube, realizing simultaneous air cooling and water cooling, so as to improve the cooling effect on the condenser tube, further improve the heat dissipation effect on high-power air conditioner outdoor units, thereby reducing the energy consumption of high-power air conditioners, saving energy while improving efficiency.

[0007] In some embodiments, a filter screen is further provided on the side wall of the chassis. The filter screen is located on the side of the first spray rod and the second spray rod away from the condensation pipe. Both the first spray rod and the second spray rod are rotatably arranged in the chassis, and the first spray rod and the second spray rod are arranged in parallel. The spraying mechanism further includes a transmission member, and the transmission member is used to drive the second spray rod to rotate with the first spray rod, and direct the nozzles on the first spray rod and the second spray rod towards the filter screen.

[0008] With such an arrangement, when the dust accumulates on the filter screen and affects the heat dissipation effect of the cooling fan, rotate the first spray rod. The first spray rod drives the second spray rod to rotate through the transmission member, so that the first spray rod rotates clockwise and the second spray rod rotates counterclockwise, so as to change the nozzles on the first spray rod and the second spray rod from facing the condensation pipe to facing the filter screen, so as to wash the filter screen and clean the dust accumulated on the filter screen, thereby ensuring the heat dissipation effect of the cooling fan.

[0009] In some embodiments, the transmission member includes: a transmission rack, which is slidably arranged in the chassis. A transmission gear is coaxially connected to the first spray rod, and the transmission gear meshes with the transmission rack; a transmission rod, which is connected to the second spray rod, and the end of the transmission rod away from the second spray rod is bent in a direction away from the condensation pipe; the transmission rack is slidably arranged horizontally on the side of the first spray rod facing the condensation pipe, and the end of the transmission rack away from the first spray rod abuts against the bent end of the transmission rod. The transmission rack is used to push the transmission rod to drive the second spray rod to direct the nozzle towards the filter screen. A torsion spring is provided at the rotating shaft of the second spray rod, and the torsion spring is used to drive the second spray rod to rotate and then direct the nozzle towards the condensation pipe.

[0010] With such an arrangement, when the first spray rod is rotated, the first spray rod drives the transmission gear to rotate after rotation, and the transmission gear drives the transmission rack to slide towards the second spray rod after rotation, so that the transmission rack abuts against the bent part of the transmission rod, so as to push the transmission rod to drive the second spray rod to rotate towards the filter screen against the torsion of the torsion spring. After the nozzle of the first spray rod faces the filter screen, the nozzle of the second spray rod also faces the filter screen; when the first spray rod rotates reversely and resets, it drives the transmission rack away from the second spray rod, and the transmission rod is disengaged from the abutment of the transmission rack, and reversely resets with the second spray rod under the action of the torsion spring to direct the nozzle towards the condensation pipe, so as to facilitate the simultaneous rotation of the first spray rod and the second spray rod, and face the condensation pipe or the filter screen at the same time, thereby facilitating the switching of the spraying directions of the first spray rod and the second spray rod.

[0011] In some embodiments, the spraying mechanism further includes: a driving column slidably penetrating through the chassis, one end of the driving column away from the chassis can penetrate into the wall, and the inside of the driving column is hollow for wires to pass through; a driving rack disposed on the side wall of the driving column; and a driving gear coaxially connected to the first spraying rod.

[0012] With such a setting, when driving the first spraying rod to rotate, by pushing the driving column towards the chassis, the driving column drives the driving rack to slide towards the inside of the chassis, thereby driving the driving gear to rotate. The driving gear drives the first spraying rod to rotate clockwise, so that the first spraying rod drives the second spraying rod to rotate counterclockwise through the transmission rack and the transmission rod; when pulling the driving column away from the chassis, the driving column drives the driving rack to slide out of the chassis, and the driving rack drives the first spraying rod to rotate in the reverse direction and reset through the driving gear, and the second spraying rod also rotates in the reverse direction and resets under the action of the torsion spring, thus facilitating the driving column to penetrate into the reserved hole on the indoor wall, enabling people to manually adjust the turning directions of the first spraying rod and the second spraying rod indoors.

[0013] In some embodiments, the water supply mechanism further includes: a recovery plate rotatably disposed in the chassis and below the condensing pipe and the radiator fan, the rotating shaft of the recovery plate rotates on the two side walls of the chassis adjacent to the filter screen; a filter plate disposed at one end of the recovery plate close to the water supply tank; a return water plate is provided at the upper end of the water supply tank extending to the bottom of the chassis and abuts against the lower end of the filter plate, and a plurality of return water holes are formed in the side wall of the water supply tank adjacent to the return water plate, and the recovery plate obliquely abuts against the return water plate through the filter plate.

[0014] With such a setting, when spraying water for cooling the condensing pipe, the water mist is sprayed on the condensing pipe, and the unevaporated water mist sinks and gathers on the recovery plate to form water droplets, and gradually gathers on the recovery plate to form water; the gathered water flows downward along the inclined recovery plate, passes through the filtering of the filter plate and flows back into the water supply tank through the return water holes, so as to collect the water that has not evaporated during the water cooling of the condensing pipe again and recycle it, thereby saving water resources and achieving an energy-saving effect.

[0015] In some embodiments, the rotating shaft of the recovery plate is eccentrically disposed on the recovery plate away from the water supply tank.

[0016] With such a setting, it is convenient for the end of the recovery plate close to the water supply tank to naturally abut against the return water plate under the action of gravity, so as to guide the water collected on the recovery plate to the return water plate.

[0017] In some embodiments, a spiral plate is provided at the lower end of the first spray rod, and the spiral plate abuts against the bottom wall of the recovery plate. When the first spray rod rotates to face the nozzle towards the filter screen, the spiral plate rotates to push the end of the recovery plate close to the water supply tank to turn upwards.

[0018] With such a setting, when the condenser tube and the filter screen are not being sprayed, by pushing the driving column, under the meshing of the driving rack and the driving gear, the first spray rod is driven to rotate clockwise, and then the spiral plate on the first spray rod rotates. The spiral plate slides and abuts against the recovery plate. As the spiral plate rotates, the spiral plate pushes the end of the recovery plate close to the water supply tank to reverse upwards until the end of the recovery plate close to the water supply tank is higher than the end close to the radiator fan, so as to pour the dust and sundries collected on the recovery plate under the chassis, thereby facilitating the cleaning of the dust and sundries collected on the recovery plate.

[0019] In some embodiments, the water supply mechanism further includes: a water connection pipe, which is arranged in the driving column, with one end connected to the inside of the water supply tank and the other end extending out from the end of the driving column away from the chassis; a solenoid valve, which is arranged at the end where the water connection pipe extends out of the driving column and is used to control the water flow and shut-off of the water connection pipe.

[0020] With such a setting, when it is necessary to add water to the water supply tank, by controlling the solenoid valve to open the water connection pipe for water flow, so as to supplement water to the water supply tank through the water connection pipe, realizing convenient water addition.

[0021] In some embodiments, a low liquid level sensor and a high liquid level sensor are arranged in the water supply tank. Both the low liquid level sensor and the high liquid level sensor are electrically connected to the solenoid valve. When the low liquid level sensor senses that the liquid level in the water supply tank is lower than the preset liquid level value, it gives a signal for the solenoid valve to allow water flow. When the high liquid level sensor senses that the liquid level in the water supply tank is higher than the preset liquid level value, it gives a signal for the solenoid valve to shut off.

[0022] With such a setting, when the liquid level in the water supply tank is lower than the preset liquid level value, the low liquid level sensor gives a signal to the solenoid valve to open the connecting pipe to replenish water to the water supply tank; until the liquid level in the water supply tank is higher than the preset liquid level value, the high liquid level sensor gives a signal to the solenoid valve to close the connecting pipe and stop replenishing water to the water supply tank, realizing automatic water replenishment in the water supply tank.

[0023] In some embodiments, a temperature sensor is arranged in the chassis close to the condenser tube. The temperature sensor is electrically connected to the water pump. When the temperature sensor senses that the temperature of the condenser tube exceeds the preset temperature value, it gives a signal for the water pump to start.

[0024] It is set in such a way that when the temperature of the condensation pipe of the outdoor unit of the air conditioner is higher than the preset temperature value, a signal is given to start the water pump through the temperature sensor, so that the water pump pumps water out of the sprinkler head to cool the condensation pipe, realizing automatic high-temperature water spraying to cool the condensation pipe.

[0025] Compared with the prior art, the present disclosure has the following advantages:

[0026] By atomizing and absorbing heat from the condensation pipe, collecting and filtering the water that has not evaporated during atomization, recycling it and then atomizing it again; automatically compensating with water to cool the condensation pipe, and adding a radiator fan for auxiliary heat dissipation, so as to save water resources while recycling the used water to cool the outdoor unit of the air conditioner, thereby improving the heat dissipation effect of the high-power outdoor unit of the air conditioner.

The water pump 32 is located in the water supply box 31 and is connected to the first spray rod 21 and the second spray rod 22 through the connecting water pipe 36 respectively, and the first spray rod 21 and the second spray rod 22 are both rotatably connected to the connecting water pipe 36, and the upper ends of the first spray rod 21 and the second spray rod 22 are rotatably connected to the top wall in the chassis 1, so that the water pump 32 pumps the water in the water supply box 31 into the first spray rod 21 and the second spray rod 22 and then sprays it out from the nozzle 23.

[0038] In some embodiments, a filter screen 14 is further provided on the side wall of the chassis 1, and the filter screen 14 is located on the side of the first spray rod 21 and the second spray rod 22 away from the condenser 11. The first spray rod 21 and the second spray rod 22 are both rotatably arranged in the chassis 1, and the first spray rod 21 and the second spray rod 22 are arranged in parallel.

[0039] In this embodiment, the filter 14 is located on a side of the chassis 1 close to the condenser 11, so that the external air can enter the chassis 1 after being filtered by the filter 14 to cool the condenser 11. The transmission member 24 is disposed between the first spray rod 21 and the second spray rod 22, so that the first spray rod 21 rotates clockwise to direct the nozzle 23 toward the filter 14, and the second spray rod 22 rotates counterclockwise to direct the nozzle 23 toward the filter 14, so as to clean the filter 14.

[0040] In some embodiments, the transmission member 24 includes a transmission rack 241 and a transmission rod 242. The transmission rack 241 is slidably disposed in the chassis 1. A transmission gear 211 is coaxially connected to the first spray rod 21, and the transmission gear 211 meshes with the transmission rack 241. The transmission rod 242 is connected to the second spray rod 22, and one end of the transmission rod 242 away from the second spray rod 22 is bent away from the condensing pipe 11. The transmission rack 241 is slidably disposed horizontally on the side of the first spray rod 21 facing the condensing pipe 11.

The sliding column 243 is slidably connected to the top wall in the chassis 1 to guide and limit the sliding of the transmission rack 241. The transmission gear 211 is coaxially connected to the upper end of the first spray rod 21. The transmission gear 211 drives the transmission rack 241 to slide towards the second spray rod 22 as the first spray rod 21 rotates clockwise. One ends of the transmission rack 241 and the transmission rod 242 that abut against each other are both bent towards the filter net 14, so that the sliding of the transmission rack 241 can abut against the transmission rod 242 to drive the second spray rod 22 to rotate counterclockwise. In the natural state of the torsion spring 221, the transmission rod 242 abuts against the transmission rack 241, and the nozzle 23 on the second spray rod 22 faces the condensing pipe 11.

[0042] In some embodiments, the spraying mechanism 2 further includes a driving column 25, a driving rack 26 and a driving gear 27. The driving column 25 slidably penetrates through the chassis 1.

The driving rack 26 is disposed on the side wall of the driving column 25. The driving gear 27 is coaxially connected to the first spray rod 21.

[0043] In this embodiment, the driving column 25 penetrates through the bottom of the chassis 1 and is slidably disposed between the compressor 13 and the first spray rod 21. The driving column 25 slides below the filter net 14. The driving rack 26 is fixed to the side of the driving column 25 facing away from the compressor 13 and meshes with the driving gear 27. By pushing the driving column 25 into the chassis 1, the driving rack 26 is used to drive the driving gear 27 to rotate, thereby driving the first spray rod 21 to rotate clockwise to direct the nozzle 23 towards the filter net 14. At the same time, the transmission rack 241 pushes the transmission rod 242 to drive the second spray rod 22 to rotate counterclockwise to direct the nozzle 23 towards the filter net 14.

[0047] In some embodiments, refer to Figure 3 , Figure 3 This is a schematic cross-sectional view showing the recycling plate 33 and the return water plate 35 in the chassis 1 for the embodiments of the present disclosure. The water supply mechanism 3 further includes a recycling plate 33, a filter plate 34 and a return water plate 35. The recycling plate 33 is rotatably arranged in the chassis 1 and is located below the condensation pipe 11 and the heat dissipation fan 12. The rotating shaft of the recycling plate 33 rotates on the two side walls adjacent to the filter net 14 in the chassis 1. The filter plate 34 is arranged at one end of the recycling plate 33 close to the water supply tank 31. The water supply tank 31 extends to the upper end of the bottom of the chassis 1 and has a return water plate 35 abutted against the lower end of the filter plate 34. A plurality of return water holes 311 are opened on the side wall of the water supply tank 31 adjacent to the return water plate 35. The recycling plate 33 is obliquely downward abutted against the return water plate 35 through the filter plate 34.

[0048] In this embodiment, the rotating shaft of the recycling plate 33 is located between the condensation pipe 11 and the heat dissipation fan 12 and extends in the horizontal direction. A support rod 15 is fixed at the bottom of the chassis 1 for the recycling plate 33 to rotate. That is to say, the recycling plate 33 is rotationally connected to the chassis 1 through the support rod 15. The rotational connection between the support rod 15 and the recycling plate 33 is at one end of the recycling plate 33 close to the heat dissipation fan 12. That is to say, the rotating shaft of the recycling plate 33 is eccentrically arranged on the recycling plate 33 away from the water supply tank 31. So that in the natural state of the recycling plate 33, one end of the recycling plate 33 close to the water supply tank 31 can be abutted against the return water plate 35, so that the recycling plate 33 is obliquely downwardly placed on the return water plate 35, so that the water on the recycling plate 33 can naturally flow downward onto the return water plate 35. The entire side wall of the recycling plate 33 close to the water supply tank 31 is the filter plate 34 to filter the water collected on the recycling plate 33, and a plurality of return water holes 311 are provided on the side wall of the water supply tank 31 extending into the chassis 1 adjacent to the return water plate 35 to filter the collected water again.

[0049] It should be noted that the height of the end of the recycling plate 33 placed on the return water plate 35 is higher than the height of the driving gear 27 on the first spray rod 21.

[0050] In some embodiments, refer to Figure 3 and Figure 4 ,Figure 4 The internal structure diagram of the chassis 1 provided for the embodiment of the present disclosure to show the spiral plate 212. A spiral plate 212 is provided at the lower end of the first spray rod 21. The spiral plate 212 abuts against the bottom wall of the recovery plate 33. When the first spray rod 21 rotates to face the spray head 23 towards the filter screen 14, the spiral plate 212 rotates to push the end of the recovery plate 33 close to the water supply tank 31 to turn upwards.

[0051] In this embodiment, the spiral plate 212 rotates upwards when the first spray rod 21 rotates clockwise. The spiral plate 212 rotates between the driving column 25 and the recovery plate 33 along with the first spray rod 21, and the spiral plate 212 abuts against the bottom wall of the recovery plate 33 close to the water supply tank 31, so that after the first spray rod 21 rotates clockwise, it drives the spiral plate 212 to push the recovery plate 33 to rotate upwards to pour the dust and sundries on the recovery plate 33.

[0052] In some embodiments, refer to Figure 1 , the water supply mechanism 3 further includes a water connection pipe 36 and a solenoid valve 37. The water connection pipe 36 is arranged inside the driving column 25, one end is connected inside the water supply tank 31, and the other end extends out from the end of the driving column 25 away from the chassis 1. The solenoid valve 37 is arranged at the end where the water connection pipe 36 extends out of the driving column 25 for controlling the water flow and cut-off of the water connection pipe 36.

[0053] In this embodiment, one end of the water connection pipe 36 is connected to the upper end of the water supply tank 31, the other end of the water connection pipe 36 slides through the driving column 25 and is connected to the indoor water pipe through the driving column 25. The solenoid valve 37 is arranged at the end where the water connection pipe 36 is connected indoors to control the water flow and cut-off of the water connection pipe 36. A relief opening 252 for the water connection pipe 36 is provided on the driving column 25, so that when the driving column 25 slides, it does not affect the connection of the connecting pipe.

[0054] In some embodiments, a low liquid level sensor 312 and a high liquid level sensor 313 are provided in the water supply tank 31. Both the low liquid level sensor 312 and the high liquid level sensor 313 are electrically connected to the solenoid valve 37. When the low liquid level sensor 312 senses that the liquid level in the water supply tank 31 is lower than the preset liquid level value, it gives a signal for the solenoid valve 37 to let water through. When the high liquid level sensor 313 senses that the liquid level in the water supply tank 31 is higher than the preset liquid level value, it gives a signal for the solenoid valve 37 to cut off the water supply.

[0055] In this embodiment, both the high liquid level sensor 313 and the low liquid level sensor 312 are located on the side of the water supply tank 31 facing away from the driving column 25, and the height of the high liquid level sensor 313 on the water supply tank 31 is higher than the height of the low liquid level sensor 312 on the water supply tank 31. The high liquid level preset value can be that the liquid level in the water supply tank 31 is 3 cm - 5 cm away from the inner top wall of the water supply tank 31, and the low liquid level preset value can be that the liquid level in the water supply tank 31 is 3 cm - 5 cm away from the inner bottom wall of the water supply tank 31.

[0056] In some embodiments, a temperature sensor 16 is provided at the top of the chassis 1 near the condensing pipe 11. The temperature sensor 16 is electrically connected to the water pump 32. When the temperature sensor 16 senses that the temperature of the condensing pipe 11 exceeds a preset temperature value, it gives a signal to start the water pump 32.

[0057] In this embodiment, the temperature sensor 16 is located on the top wall of the chassis 1, and the probe of the temperature sensor 16 extends into the chassis 1 above the condensing pipe 11 for monitoring the temperature inside the chassis 1 and the condensing pipe 11. The preset temperature value can be greater than 30 °C.

[0058] In some other embodiments, the top cover and the surrounding side covers of the chassis 1 are detachably connected and fixed by screws, so as to facilitate removing the spraying mechanism 2 and the water supply mechanism 3 from the chassis 1 and conveniently installing them on other old air conditioner outdoor units. Only need to make holes in the shells of other old air conditioner outdoor units to realize the disassembly and use of the spraying structure and the water supply mechanism 3.

[0059] It should be noted that the chassis 1 can be insulated. For example, the chassis 1 is made of insulating materials, or an insulating paint is coated on the outside of the chassis 1.
