Description

Technical Field

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

[0002] Air conditioning has been used in people's lives and industrial production. The larger the space, the better the cooling effect required, and the larger the size of the air conditioner will be to meet the cooling and refrigeration needs of the large space. Especially for air conditioners in production workshops or factories, the air conditioner outdoor unit is slightly larger in size and emits more heat. Heat dissipation and cooling of the air conditioner outdoor unit can help improve the cooling effect and efficiency of the air conditioner.

[0003] At present, the heat dissipation and cooling of the air conditioner outdoor unit is usually achieved by using a cooling fan to absorb or blow away the heat on the condenser tube to achieve the purpose of cooling. However, when the air conditioner outdoor unit is large and the overall cooling demand of the air conditioner is greater, the cooling effect of absorbing or blowing away the condenser tube by the cooling fan is not significant enough, and the temperature of the condenser tube and even the entire air conditioner outdoor unit is high. Therefore, the heat dissipation of high-power air conditioner outdoor units needs to be improved. Summary of the invention

[0004] To solve the above problems, the present invention provides an energy-saving air-conditioning outdoor unit cooling device, which atomizes the condenser to absorb heat, collects and filters the atomized unevaporated water, and atomizes it again after recycling. At the same time, it can automatically compensate for the water to cool the condenser, and use a cooling fan to assist in heat dissipation, so as to save water resources and recycle the used water to cool the air-conditioning outdoor unit, thereby improving the heat dissipation effect of high-power air-conditioning outdoor units.

[0005] The present disclosure provides an energy-saving air-conditioning outdoor unit cooling device, comprising: a chassis, in which a condenser, a heat dissipation fan and a compressor are arranged; a spray mechanism, comprising a first spray rod and a second spray rod arranged in the chassis, and the first spray rod and the second spray rod have a spray head facing the condenser; a water supply mechanism, comprising a water supply tank and a water pump, and the water pump is used to supply water in the water supply tank to the first spray rod and the second spray rod.

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

[0007] In some embodiments, a filter is further provided on the side wall of the chassis, and the filter is located on the side of the first spray rod and the second spray rod away from the condenser, the first spray rod and the second spray rod are both rotatably arranged in the chassis, and the first spray rod and the second spray rod are arranged in parallel, and the spray mechanism also includes a transmission member, and the transmission member is used to drive the second spray rod to rotate with the first spray rod, so that the nozzles on the first spray rod and the second spray rod are directed toward the filter.

[0008] With such arrangement, when the filter is full of dust and affects the heat dissipation effect of the cooling fan, the first spray rod is rotated, and 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 direction of the nozzles on the first spray rod and the second spray rod from facing the condenser to facing the filter, so as to flush the filter and clean the dust accumulated on the filter, thereby ensuring the heat dissipation effect of the cooling fan.

[0009] In some embodiments, the transmission member includes: a transmission rack, which is slidably disposed in the chassis, a transmission gear is coaxially connected to the first spray rod, and the transmission gear is meshed 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 condenser; the transmission rack is slidably disposed in a horizontal direction on the side of the first spray rod facing the condenser, 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 abut the transmission rod to drive the second spray rod to direct the nozzle toward the filter, and 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 direct the nozzle toward the condenser.

[0010] With such arrangement, when the first spray rod is rotated, the first spray rod drives the transmission gear to rotate after the first spray rod rotates, and the transmission gear drives the transmission rack to slide in the direction of the second spray rod, so that the transmission rack abuts against the bent portion of the transmission rod, so as to abut the transmission rod to drive the second spray rod to rotate toward the filter screen by overcoming the torsion force of the torsion spring, so that after the nozzle of the first spray rod faces the filter screen, the nozzle of the second spray rod also faces the filter screen; and when the first spray rod is reversed and reset, the transmission rack is driven away from the second spray rod, the transmission rod is disengaged from the abutment of the transmission rack, and reversed and reset with the second spray rod under the action of the torsion spring, so that the nozzle faces the condenser tube, so that the first spray rod and the second spray rod can rotate simultaneously and face the condenser tube or the filter screen at the same time, thereby facilitating the switching of the spray directions of the first spray rod and the second spray rod.

[0011] In some embodiments, the spray mechanism further includes: a driving column, which is slidably inserted into the chassis, and the end of the driving column away from the chassis can be inserted into the wall, and the interior of the driving column is hollow for the wiring to pass through; a driving rack, which is arranged on the side wall of the driving column; and a driving gear, which is coaxially connected to the first spray rod.

[0012] With such arrangement, when the first spray rod is driven to rotate, by pushing the driving column toward the direction of the chassis, the driving column drives the driving rack to slide toward the inside of the chassis, thereby driving the driving gear to rotate, and the driving gear drives the first spray rod to rotate clockwise, so that the first spray rod drives the second spray rod to rotate counterclockwise through the transmission rack and the transmission rod; and when the driving column is pulled in the direction away from the chassis, the driving column drives the driving rack to slide toward the outside of the chassis, and the driving rack drives the first spray rod to rotate in the opposite direction and then reset through the driving gear, and the second spray rod also rotates in the opposite direction and then reset under the action of the torsion spring, so that it is convenient to pass the driving column through the reserved hole on the indoor wall, so that people can manually adjust the direction of the first spray rod and the second spray rod indoors.

[0013] In some embodiments, the water supply mechanism also includes: a recovery plate, which is rotatably disposed in the chassis and is located below the condenser and the cooling fan, and the shaft of the recovery plate rotates on the two side walls of the chassis adjacent to the filter screen; a filter plate, which is disposed at one end of the recovery plate close to the water supply tank; the water supply tank extends to the upper end of the bottom of the chassis and has a return water plate abutting against the lower end of the filter plate, and a plurality of return water holes are provided on the side wall of the water supply tank adjacent to the return water plate, and the recovery plate is inclined downward and abutted against the return water plate through the filter plate.

[0014] With such an arrangement, when the condenser is sprayed with water, the water mist is sprayed on the condenser, and the water mist that has not evaporated 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 on the inclined recovery plate, and after being filtered by the filter plate, it flows back to the water supply tank from the return hole, so as to collect the water that has not evaporated from the water cooling of the condenser again and recycle it, thereby saving water resources and achieving energy-saving effect.

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

[0016] In this way, under the action of gravity, the end of the recovery plate close to the water supply tank naturally abuts against the return plate downward, so as to guide the water collected on the recovery plate to the return 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 direct the nozzle toward the filter, the spiral plate rotates to abut the end of the recovery plate close to the water supply tank to flip upward.

[0018] With such arrangement, when the condenser and the filter are not sprayed, the driving column is pushed, and the driving rack and the driving gear are meshed, so that the first spray rod is driven to rotate clockwise, thereby driving the spiral plate on the first spray rod to rotate, and the spiral plate slides and abuts against the recovery plate. As the spiral plate rotates, the spiral plate abuts the end of the recovery plate close to the water supply tank and reverses upward until the end of the recovery plate close to the water supply tank is higher than the end close to the cooling fan, so that the dust and debris collected on the recovery plate can be dumped under the chassis, thereby facilitating the cleaning of the dust and debris collected on the recovery plate.

[0019] In some embodiments, the water supply mechanism also includes: a water receiving pipe, which is arranged in the driving column and one end of which is connected to the water supply tank, and the other end extends from the end of the driving column away from the chassis; an electromagnetic valve, which is arranged at the end of the water receiving pipe extending from the driving column, and is used to control the water flow and shutoff of the water receiving pipe.

[0020] With such arrangement, when water needs to be added to the water supply tank, the water receiving pipe is opened by controlling the solenoid valve to allow water to flow, so that water can be replenished into the water supply tank through the water receiving pipe, thereby realizing convenient water addition.

[0021] In some embodiments, a low liquid level sensor and a high liquid level sensor are provided in the water supply tank, and 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 a preset liquid level value, it gives a signal to the solenoid valve to pass water. When the high liquid level sensor senses that the liquid level in the water supply tank is higher than a preset liquid level value, it gives a signal to the solenoid valve to shut off.

[0022] With such arrangement, 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 make the solenoid valve open the connecting pipe to replenish water in 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 make the solenoid valve close the connecting pipe and stop replenishing water in the water supply tank, thereby realizing automatic water replenishment in the water supply tank.

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

[0024] This arrangement allows for when the temperature of the condenser tube of the air conditioner outdoor unit is higher than the preset temperature value, a signal is given to the water pump to start through the temperature sensor, causing the water pump to pump water out of the nozzle to cool the condenser tube, thereby achieving high-temperature automatic water spraying to cool the condenser tube.

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

[0026] The condenser is atomized to absorb heat, and the unevaporated water is collected and filtered, and then atomized again after recycling; the condenser is cooled by automatic compensation water, and the cooling fan is used for auxiliary heat dissipation, so as to save water resources and recycle the used water to cool the air conditioner outdoor unit, thereby improving the heat dissipation effect of high-power air conditioner outdoor units.

[0036] See also Figure 1 and Figure 2 , Figure 1 The overall structure diagram of an energy-saving air conditioner outdoor unit cooling device provided by the embodiment of the present disclosure is as follows: Figure 2 The schematic diagram of the internal structure of an energy-saving air conditioner outdoor unit cooling device provided by an embodiment of the present disclosure.

The side wall of the chassis 1 close to the condenser 11 and the side wall close to the heat dissipation fan 12 both have openings, and the side wall of the chassis 1 close to the heat dissipation fan 12 has a grille, so that the heat dissipation fan 12 absorbs the heat on the condenser 11 and blows it out from the grille. The first spray rod 21 and the second spray rod 22 are located on the side of the condenser 11 away from the heat dissipation fan 12, and the first spray rod 21 and the second spray rod 22 are both placed vertically. There are multiple nozzles 23 on the first spray rod 21 and the second spray rod 22, and they are spaced apart in the vertical direction to spray the spray onto the condenser 11 for water cooling. The water supply tank 31 is connected to the bottom of the chassis 1 and is arranged close to the condenser 11. 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. The spray mechanism 2 also includes a transmission member 24, which is used to drive the second spray rod 22 to rotate with the first spray rod 21, so that the nozzles 23 on the first spray rod 21 and the second spray rod 22 are directed toward the filter screen 14.

[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, and a transmission gear 211 is coaxially connected to the first spray rod 21, and the transmission gear 211 is meshed with the transmission rack 241. The transmission rod 242 is connected to the second spray rod 22, and the end of the transmission rod 242 away from the second spray rod 22 is bent in a direction away from the condensation tube 11. The transmission rack 241 is slidably disposed on the side of the first spray rod 21 facing the condensation tube 11 in the horizontal direction, and the end of the transmission rack 241 away from the first spray rod 21 abuts against the bent end of the transmission rod 242.

A torsion spring 221 is provided at the rotating shaft of the second spray rod 22, and the torsion spring 221 is used to drive the second spray rod 22 to rotate and turn the nozzle 23 toward the condensation tube 11.

[0041] In this embodiment, the transmission rack 241 is slidably disposed at the upper end of the chassis 1 and is connected to a sliding post 243. The sliding post 243 is slidably connected to the top wall of 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, and the transmission gear 211 drives the transmission rack 241 to slide toward the second spray rod 22 as the first spray rod 21 rotates clockwise. The ends of the transmission rack 241 and the transmission rod 242 that abut against each other are bent toward the filter screen 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 condenser 11.

[0042] In some embodiments, the spray mechanism 2 further includes a driving column 25, a driving rack 26 and a driving gear 27. The driving column 25 is slidably arranged on the chassis 1, and one end of the driving column 25 away from the chassis 1 can be arranged in the wall, and the driving column 25 is hollow inside for the line to pass through. The driving rack 26 is arranged 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 is passed 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 14. The driving rack 26 is fixed to the side of the driving column 25 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 drives the driving gear 27 to rotate, thereby driving the first spray rod 21 to rotate clockwise, and the nozzle 23 is directed toward the filter 14. At the same time, the transmission rack 241 pushes the transmission rod 242 to drive the second spray rod 22 to rotate counterclockwise, and the nozzle 23 is directed toward the filter 14.

[0044] Exemplarily, one end of the driving column 25 extending out of the chassis 1 can be connected to an indoor air conditioner through a wall to collect condensed water.

[0045] Exemplarily, the driving column 25 may be hollow inside, and one end extending out of the chassis 1 may pass through a wall to be connected to power lines and water pipes.

[0046] Exemplarily, the driving column 25 can be slidably sleeved on the fixing tube 251 on the outside, and the fixing tube 251 can be fixed in a hole through the wall, so that the driving column 25 can slide in the wall, thereby facilitating the driving column 25 to slide indoors.

[0047] In some embodiments, see Figure 3 , Figure 3 The schematic cross-sectional view of the recovery plate 33 and the return plate 35 in the chassis 1 is used to show the embodiment of the present disclosure. The water supply mechanism 3 also includes a recovery plate 33, a filter plate 34 and a return plate 35. The recovery plate 33 is rotatably arranged in the chassis 1 and is located below the condenser 11 and the cooling fan 12. The shaft of the recovery plate 33 rotates on the two side walls adjacent to the filter screen 14 in the chassis 1. The filter plate 34 is arranged at one end of the recovery plate 33 close to the water supply box 31. The upper end of the water supply box 31 extending to the bottom of the chassis 1 has a return plate 35 abutting against the lower end of the filter plate 34. The side wall of the water supply box 31 adjacent to the return plate 35 is provided with a plurality of return holes 311. The recovery plate 33 is tilted downwardly abutting against the return plate 35 through the filter plate 34.

[0048] In this embodiment, the rotation axis of the recovery plate 33 is located between the condenser 11 and the heat dissipation fan 12, and extends in the horizontal direction. A support rod 15 is fixed to the bottom of the chassis 1 for the recovery plate 33 to rotate, that is, the recovery plate 33 is connected to the chassis 1 through the support rod 15. The rotation connection between the support rod 15 and the recovery plate 33 is located at one end of the recovery plate 33 close to the heat dissipation fan 12, that is, the rotation axis of the recovery plate 33 is eccentrically arranged on the recovery plate 33 away from the water supply tank 31, so that when the recovery plate 33 is in a natural state, the end of the recovery plate 33 close to the water supply tank 31 can abut against the return plate 35, so that the recovery plate 33 is tilted downward on the return plate 35, so that the water on the recovery plate 33 naturally flows downward into the return plate 35. The entire side wall of the recovery plate 33 near the water supply box 31 is a filter plate 34 to filter the water collected on the recovery plate 33, and the side wall of the water supply box 31 extending into the chassis 1 and adjacent to the return plate 35 has multiple return holes 311 to filter the collected water again.

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

[0050] In some embodiments, see Figure 3 and Figure 4 , Figure 4 A schematic diagram of the internal structure of the chassis 1 for displaying the spiral plate 212 provided in the embodiment of the present disclosure. A spiral plate 212 is provided at the lower end of the first spray rod 21, and the spiral plate 212 abuts against the bottom wall of the recovery plate 33. When the first spray rod 21 rotates to direct the spray head 23 toward the filter screen 14, the spiral plate 212 rotates to abut against the end of the recovery plate 33 close to the water supply tank 31 to flip upward.

[0051] In this embodiment, the spiral plate 212 rotates upward 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, the spiral plate 212 abuts against the recovery plate 33 to rotate upward, so as to dump the dust and debris on the recovery plate 33.

[0052] In some embodiments, see Figure 1 The water supply mechanism 3 further includes a water receiving pipe 36 and a solenoid valve 37. The water receiving pipe 36 is disposed in the driving column 25, and one end of the water receiving pipe 36 is connected to the water supply box 31, and the other end extends from the end of the driving column 25 away from the chassis 1. The solenoid valve 37 is disposed at the end of the water receiving pipe 36 extending from the driving column 25, and is used to control the water flow and shutoff of the water receiving pipe 36.

[0053] In this embodiment, one end of the water receiving pipe 36 is connected to the upper end of the water supply tank 31, and the other end of the water receiving pipe 36 is slidably arranged in the driving column 25 and connected to the indoor water pipe through the driving column 25. The solenoid valve 37 is arranged at the end of the water receiving pipe 36 connected to the indoor, and controls the water flow and shutoff of the water receiving pipe 36. The driving column 25 is provided with a clearance port 252 for making way for the water receiving pipe 36, so that when the driving column 25 slides, it will 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 a preset liquid level value, it gives a signal to the solenoid valve 37 to pass water. When the high liquid level sensor 313 senses that the liquid level in the water supply tank 31 is higher than a preset liquid level value, it gives a signal to the solenoid valve 37 to shut off.

[0055] In this embodiment, the high liquid level sensor 313 and the low liquid level sensor 312 are both located on the side of the water supply tank 31 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 3cm-5cm from the liquid level in the water supply tank 31 to the top wall of the water supply tank 31, and the low liquid level preset value can be 3cm-5cm from the liquid level in the water supply tank 31 to the bottom wall of the water supply tank 31.

[0056] In some embodiments, a temperature sensor 16 is provided on the top of the chassis 1 near the condenser 11. The temperature sensor 16 is electrically connected to the water pump 32. When the temperature sensor 16 senses that the condenser 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 is inserted into the chassis 1 and located above the condenser 11 to monitor the temperature inside the chassis 1 and the condenser 11. The preset temperature value may be greater than 30°C.

[0058] In some other embodiments, the top cover and the surrounding side covers of the chassis 1 can be detachably connected and fixed with screws, so that the spray mechanism 2 and the water supply mechanism 3 can be easily removed from the chassis 1 and installed on other old air-conditioning outdoor units for use.
