Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an outdoor unit of an air conditioning. Background Art

[0002] The split type air conditioner may include an air conditioner indoor unit and an air conditioner outdoor unit.

[0003] The air conditioner indoor unit may include an indoor air inlet, an indoor air outlet, an indoor heat exchanger and an indoor fan. The indoor fan drives the air from the indoor air inlet into the air conditioner indoor unit to exchange heat with the indoor heat exchanger. The air after heat exchange flows out of the air conditioner indoor unit through the indoor air outlet to cool or heat the environment.

[0004] The air conditioner outdoor unit may include an outdoor air inlet, an outdoor air outlet, an outdoor heat exchanger and an outdoor fan. The outdoor fan rotates to allow air to enter the air conditioner outdoor unit from the outdoor air inlet to exchange heat with the outdoor heat exchanger, and the air after heat exchange with the outdoor heat exchanger flows out of the air conditioner outdoor unit through the outdoor air outlet.

[0005] When the indoor unit of the air conditioner is cooling, condensed water will be generated on the indoor heat exchanger. Generally, the indoor unit of the air conditioner is equipped with an indoor water tray, which receives the condensed water flowing down from the indoor heat exchanger. When the condensed water in the indoor water tray cannot be discharged into a dedicated drainage pipe, if the condensed water is directly discharged to the outside, the condensed water may drip onto the user, causing a poor user experience, or onto the wall or the ground, causing damage to the ground or the wall.

[0006] In the prior art, condensed water can be discharged into the outdoor unit of the air conditioner. A water pumping mechanism is arranged in the outdoor unit of the air conditioner. The water pumping mechanism is generally arranged at the bottom of the outdoor heat exchanger. The water pumping mechanism generally includes a water pumping motor and a water pumping pan. The water pumping motor drives the water pumping pan to rotate, and the water pumping pan brings up water to splash. Part of the water can be splashed onto the outdoor heat exchanger and the water is evaporated by the outdoor heat exchanger.

[0007] However, when a water pumping pan is set up to pump water, due to the effect of centrifugal force, most of the water is thrown out around the outer peripheral wall of the water pumping pan, and will be thrown onto the top plate of the air conditioner outdoor unit and the partition between the fan chamber and the compressor chamber. Water will drip from the top plate and the partition onto the bottom plate of the air conditioner outdoor unit. When there is no drainage structure on the bottom plate of the air conditioner outdoor unit, water will leak from the bottom plate, causing the air conditioner outdoor unit to leak, which may leak onto the user, causing a poor user experience, or onto the wall or bottom surface, causing damage to the bottom surface or wall; and the water pumping mechanism is provided with a special water pumping motor, so that the number of motors will increase, increasing the cost of the air conditioner outdoor unit. Therefore, the present application proposes an air conditioner outdoor unit. Summary of the invention

[0147] In the present application, the driving motor may include two output shafts. The first output shaft section and the second output shaft section are respectively located on two different output shafts. The first output shaft section and the second output shaft section are connected.

[0148] In this application, reference is made to Figure 4-Figure 6 The water pumping mechanism may be a third water pumping mechanism 90. The third water pumping mechanism 90 may be partially inserted into the liquid storage cavity through the liquid storage cavity opening.

[0153] In the present application, the driving motor can be connected to the outdoor fan and can drive the outdoor fan to rotate.

[0154] The driving motor drives the outdoor fan to rotate so that outdoor air enters the outdoor accommodating chamber from the outdoor air inlet to exchange heat with the outdoor heat exchanger, and the air after heat exchange with the outdoor heat exchanger flows out of the outdoor accommodating chamber through the outdoor air outlet.

[0155] The driving motor can be inserted into the outdoor fan from the rear side of the outdoor fan and connected to the outdoor fan.

[0156] In the present application, the driving motor can drive the third water pumping mechanism to rotate synchronously with the outdoor fan.

[0157] The driving motor can drive the third water pumping mechanism to rotate synchronously with the outdoor fan so that the water pumping tank pumps up and disperses the water in the liquid storage chamber and pumps it onto the outdoor heat exchanger.

[0158] During cooling, the temperature of the outdoor heat exchanger is high. A water trough is provided to scoop up and disperse the water in the liquid storage chamber and hit the outdoor heat exchanger. The high temperature of the outdoor heat exchanger can evaporate the water hitting the outdoor heat exchanger. Without draining the water outward, the water in the liquid storage part can be prevented from overflowing onto the bottom plate of the air-conditioning outdoor unit, thereby preventing water from leaking out of the air-conditioning outdoor unit and causing water leakage in the air-conditioning outdoor unit, and preventing water from dripping onto users and causing poor user experience, and preventing water from dripping onto the floor or wall and affecting the floor and wall, thereby avoiding user complaints. In addition, the water can cool the outdoor heat exchanger and improve the heat exchange effect of the outdoor heat exchanger. The water trough opening is arranged to face the outdoor heat exchanger, thereby preventing water from splashing out of the water trough and splashing onto other areas of the outdoor casing, thereby preventing water leakage in the air-conditioning outdoor unit.

[0159] Providing a driving motor to simultaneously drive the outdoor fan and the third water pumping mechanism to rotate can save a motor, save the cost of the air-conditioning outdoor unit, and can save space for installing the motor, reducing the overall size of the air-conditioning outdoor unit.

[0160] In the present application, the third water-pumping mechanism rotates so that the air in the water-pumping trough and the side walls of the water-pumping trough can rub the water in the water-pumping trough through its rotation, so that the water in the water-pumping trough can form small droplets and hit the outdoor heat exchanger when it is discharged from the water-pumping trough through the water-pumping trough opening.

[0161] In the present application, when the water trough opening faces the outdoor heat exchanger, the water trough opening may face the first-stage outdoor heat exchanger.

[0162] In this application, reference is made to Figure 4-Figure 7 The driving motor 8223 may include a first output shaft 82231.

The second output shaft may be inserted into the third water pumping mechanism from the front side of the third water pumping mechanism and connected to the third water pumping mechanism.

[0164] In the present application, the rotation axis of the first output shaft section and the rotation axis of the second output shaft section may be colinear. The first output shaft section and the second output shaft section may rotate synchronously.

[0165] In the present application, the driving motor may include an output shaft. An output shaft may include a first section output shaft and a second section output shaft. The first section output shaft and the second section output shaft are respectively located at two ends of an output shaft. The first section output shaft and the second section output shaft are two sections of an output shaft.

[0166] In the present application, the driving motor may include two output shafts. The first output shaft section and the second output shaft section are respectively located on two different output shafts. The first output shaft section and the second output shaft section are connected.

[0167] In this application, reference is made to Figure 4-Figure 8 There may be a plurality of water pumping tanks 901. The plurality of water pumping tanks may be sequentially arranged around the rotation axis of the third water pumping mechanism.

[0168] In this application, reference is made to Figure 4-Figure 8 The water pumping tank may include a second side wall 9013. The second side wall 9013 may be disposed on a side of the water pumping tank away from the rotation axis of the third water pumping mechanism.

[0169] Along the radial direction of the third water-pumping mechanism, the end of the second side wall of the water-pumping trough away from the water-pumping trough opening is the third end of the side wall, and the end of the second side wall of the water-pumping trough forming the water-pumping trough opening is the fourth end of the side wall. The third end of the side wall is located on the side of the fourth end of the side wall away from the rotation axis of the third water-pumping mechanism. When the water-pumping trough rotates to the bottom, the water-pumping trough is inserted into the water to pump water. Since the third end of the side wall is set high and the fourth end of the side wall is set low, the position of the bottom of the water-pumping trough opening can be made higher than the bottom of the bottom of the water-pumping trough, so that the water-pumping trough can form a water-scooping structure, which is convenient for the water-pumping trough to scoop up water.

[0170] Along the radial direction of the third water pumping mechanism, the greater the distance between the third end of the side wall and the fourth end of the side wall, the more water that can be scooped up in the water pumping trough.

The first side wall 9012 of the water pumping trough is arranged on one side of the water pumping trough close to the rotation axis of the third water pumping mechanism.

The end of the first side wall of the water pumping trough forming the opening of the water pumping trough is the second end of the side wall. The first end of the side wall is located on the side of the second end of the side wall away from the rotation axis of the third water pumping mechanism; after the water pumping trough completes scooping water and rotates upward to the first height, since the first end of the side wall is set high and the second end of the side wall is set low, the position of the bottom of the water pumping trough opening can be lower than the bottom of the bottom of the water pumping trough, which is convenient for the water in the water pumping trough to be poured down by gravity, and splashed onto the outdoor heat exchanger under the action of the centrifugal force generated by the high rotation.

[0173] In the present application, the cross section of the water pumping trough perpendicular to the rotation axis of the third water pumping mechanism is fan-shaped.

The fourth side wall of the water pumping trough can be arranged along the radial direction of the third water pumping mechanism.

[0176] In this application, reference is made to Fig. 9 , along the radial direction of the third water-pumping mechanism, the minimum dimension of the water-pumping trough opening is the fifth distance H5.

[0177] In the present application, the fifth distance H5 ≥ the twenty-seventh parameter value. The twenty-seventh parameter value may be any value between 2 mm and 5 mm.

[0179] In the present application, H6≤parameter value 28. Parameter value 28 may be any value between 25 mm and 35 mm. Parameter value 28 may be 30 mm. H6≤30 mm. This can avoid the third water pumping mechanism from being too large due to the opening size of the water pumping tank being too large, avoid occupying a large space in the air conditioner outdoor unit, and avoid increasing the overall size of the air conditioner outdoor unit.

[0180] In the present application, the third water pumping mechanism is provided with a first end surface 902 at one end close to the outdoor heat exchanger. The water pumping tank opening is provided on the first end surface.

[0185] In the present application, 1 / 10≤H5 / D7≤4 / 5, which prevents the water trough opening from occupying too large a diameter of the first end face, causing the water trough opening to be too close to the rotation axis of the third water-pumping mechanism, thereby affecting the water outlet distance of the water trough opening and causing the water to be unable to hit the outdoor heat exchanger. It also prevents the water trough opening from occupying too small a diameter of the first end face, causing the water trough opening to be smaller and affecting the water outlet of the water trough opening.

[0186] In the present application, H6 / D7≤31st parameter value. The 31st parameter value may be any value between 0.7 and 0.9. The 31st parameter value may be 4 / 5. H6 / D7≤4 / 5. Avoid making the water tank opening occupy too large a diameter of the first end surface, making the water tank opening part too close to the rotation axis of the third water pumping mechanism, affecting the water outlet distance of the water tank opening, and causing the water to be unable to hit the outdoor heat exchanger.

It also prevents the water trough opening from occupying too small a diameter of the first end face, causing the water trough opening to be smaller and affecting the water outlet of the water trough opening.

[0189] In the present application, along the radial direction of the third water-pumping mechanism, the distance between the water-pumping trough opening and the rotation axis of the third water-pumping mechanism is greater than the distance between the water-pumping trough opening and the outer edge of the first end face, so that the water-pumping trough opening can be as far away from the rotation axis of the third water-pumping mechanism as possible, so that the centrifugal force exerted on the water is greater, the speed of the pumped water is greater, and the water can be smoothly thrown onto the outdoor heat exchanger.
