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

[0145] In this application, reference 6- Fig. 9 The air conditioner outdoor unit may include a drive motor 8223. The drive motor 8223 may be connected to the second water pumping unit 911. The drive motor may drive the second water pumping unit to rotate.

[0146] In this application, reference is made to Figure 6-Figure 8 The second water pumping part may be formed with a second water pumping cavity 9111. The second water pumping cavity may have a plurality of second water pumping cavities. The plurality of second water pumping cavities may be sequentially arranged around the rotation axis of the second water pumping part.

[0147] In this application, reference is made to Figure 6-Figure 8 The second water pumping part may be formed with a second water inlet 9112. The second water inlet may be connected to the second water pumping cavity.

[0148] In the present application, along the radial direction of the second water pumping part, the second water inlet may be located on a side of the second water pumping chamber away from the rotation axis of the second water pumping part.

[0149] In the present application, there may be a plurality of second water inlets, and the second water inlets may correspond one to one with the second water pumping chambers.

[0150] In this application, reference is made to Figure 6-Figure 8 The second water pumping part may be formed with a second water outlet 9113. The second water outlet may be communicated with the second water pumping cavity.

[0151] In the present application, the second water outlet may be located at one side of the second water pumping chamber in the axial direction of the second water pumping part.

[0152] In this application, reference is made to Figure 6-Figure 8 The air conditioner outdoor unit may include a second water retaining portion 912. The second water retaining portion blocks the water thrown out from the second water inlet and guides the water into the liquid storage chamber to prevent the water thrown out from the second water inlet from flowing out of the liquid storage chamber and causing water leakage in the air conditioner outdoor unit.

[0153] In the present application, the driving motor drives the second water pumping part to rotate so that the second water pumping chamber scoops the water in the liquid storage chamber into the second water pumping chamber through the second water inlet and breaks up the water and then pushes the water to flow out from the second water outlet, and allows air to enter the second water pumping chamber from the second water inlet and drive the water to flow out from the second water outlet.

[0154] In this application, reference is made to Figure 6-Figure 9 The second water outlet may be directed toward the outdoor heat exchanger so that the water flowing out of the second water outlet hits the outdoor heat exchanger.

[0155] During cooling, the temperature of the outdoor heat exchanger is relatively high. A second water-pumping part is provided to pump up and scatter the water in the liquid storage chamber and splash it onto the outdoor heat exchanger. The high temperature of the outdoor heat exchanger can be relied upon to evaporate the water splashing onto the outdoor heat exchanger. While not draining the water outward, the water in the liquid storage part can be prevented from overflowing excessively onto the bottom plate of the air-conditioning outdoor unit, and water can be prevented from leaking out of the air-conditioning outdoor unit to cause water leakage in the air-conditioning outdoor unit, and from dripping onto users to cause poor user experience, and from dripping onto the floor or wall to affect 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 second water outlet is provided toward the outdoor heat exchanger, which can prevent the water pumped up by the water trough from splashing and splashing onto other areas of the outdoor casing, thereby avoiding water leakage in the air-conditioning outdoor unit.

[0156] In the present application, the second water outlet may be directed toward the outdoor air outlet so that water flowing out of the second water outlet flows out of the outdoor containing chamber through the outdoor air outlet under the drive of the outdoor fan.

[0157] By setting the second water outlet toward the outdoor air outlet, the wind pressure generated by the rotation of the outdoor fan can be fully utilized, and the water discharged from the second water outlet can flow out of the air-conditioning outdoor unit through the outdoor air outlet, which can prevent water from overflowing from the liquid storage part onto the bottom plate of the air-conditioning outdoor unit, and can prevent water discharged from the second water outlet from splashing onto other areas of the outdoor unit casing, thereby avoiding water leakage of the air-conditioning outdoor unit.

[0158] In the present application, the second water pumping chamber scoops water from the liquid storage chamber into the second water pumping chamber through the second water inlet, and the second water pumping part rotates to rotate the second water pumping chamber. Under the action of the rotating second water pumping chamber, the water can collide with the second water pumping chamber back and forth and repeatedly, so that the water can be split into liquid filaments, and the liquid filaments form droplets after colliding with the air. The second water pumping chamber can break up the condensed water in the liquid storage chamber into water mist, and push the water to flow out from the second water outlet, so that the water splashes from the second water outlet onto the outdoor heat exchanger or toward the outdoor air outlet; at the same time, the driving motor drives the second water pumping part to rotate, so that air can enter the second water pumping chamber from the second water inlet and drive the water to flow out from the second water outlet. Before the water leaves the second water pumping part, the second water pumping part can at least atomize most of the water.

[0159] In the present application, referring to Fig. 4, the second water pumping chamber may include a second water inlet chamber 91113. The second water pumping chamber may include a second water outlet chamber 91114. The second water inlet chamber and the second water outlet chamber may be sequentially arranged along the axial direction of the second water pumping part.

[0160] Along the axial direction of the second water pumping part, the second water outlet is located at a side of the second water outlet cavity away from the second water inlet cavity. The second water outlet is communicated with the second water outlet cavity.

[0161] Along the radial direction of the second water pumping part, the second water inlet is located on a side of the second water inlet cavity away from the rotation axis of the second water pumping part. The second water inlet is communicated with the second water inlet cavity.

[0162] One end of the second water outlet cavity away from the second water outlet is communicated with the second water inlet through the second water inlet cavity.

[0163] The second water inlet chamber can be used for water intake, and the second water outlet chamber can be used for water discharge.

[0164] In the present application, the driving motor can be connected to the outdoor fan and can drive the outdoor fan to rotate.

[0165] 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.

[0166] The driving motor can be inserted into the outdoor fan from the rear side of the outdoor fan and connected to the outdoor fan.

[0167] In the present application, the driving motor can drive the second water pumping unit to rotate synchronously with the outdoor fan.

[0168] The driving motor can drive the second water pumping part to rotate synchronously with the outdoor fan so that the second water pumping part scoops water in the liquid storage chamber into the second water pumping chamber through the second water inlet and disperses the water, and allows air to enter the second water pumping chamber from the second water inlet and drive the dispersed water to flow out from the second water outlet.

[0169] Providing a driving motor to simultaneously drive the outdoor fan and the second water pumping part 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.

[0170] In the present application, when the second water outlet is directed toward the outdoor heat exchanger, the second water outlet may be directed toward the first-stage outdoor heat exchanger.

[0171] In this application, reference is made to Fig. 9 The driving motor 8223 may include a first output shaft 82231. The first output shaft 82231 may be located at the front side of the driving motor. The first output shaft may be connected to the outdoor fan. The first output shaft may be inserted into the outdoor fan from the rear side of the outdoor fan and connected to the outdoor fan.

[0172] In this application, reference is made to Fig. 9 The driving motor may include a second output shaft 82232. The second output shaft 82232 may be located at the rear side of the driving motor. The second output shaft may be connected to the second water pumping unit. The second output shaft may be inserted into the second water pumping unit from the front side of the second water pumping unit and connected to the second water pumping unit.

[0173] 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.

[0174] 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.

[0175] 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.

[0176] In the present application, a plane perpendicular to the rotation axis of the second water pumping part is defined as a second plane M2.

[0177] In this application, reference is made to Figure 10-Figure 14 The second water pumping chamber may have a first chamber wall 91111. The second water pumping chamber may have a second chamber wall 91112.

[0178] Along the rotation direction of the second water pumping part, the first cavity wall and the second cavity wall are respectively located at opposite ends of the second water pumping cavity, so that the first cavity wall and the second cavity can be arranged sequentially in the rotation direction of the second water pumping part.

[0179] Along the rotation direction of the second water-pumping part, the second cavity wall is located in front of the first cavity wall in the rotation direction of the first cavity wall, so that the first cavity wall can be located on the water scooping side of the second water-pumping cavity. When the second water-pumping cavity rotates, when the first cavity wall rotates into the water, the first cavity wall can scoop water.

[0180] In this application, reference is made to Figure 10-Figure 14 The intersection line of the first cavity wall and the second plane is the sixth intersection line a6. The sixth intersection line is an arc line. The sixth intersection line bulges toward the side away from the second cavity wall, so that the first cavity wall can form a wall surface for scooping water. During the rotation of the second water pumping part, the first wall surface can scoop up water.

[0181] In this application, reference is made to Figure 10-Figure 14 The first cavity wall has a cavity wall first end 911111. The first cavity wall has a cavity wall second end 911112.

[0182] Along the axial direction of the second water pumping part, the first end of the cavity wall and the second end of the cavity wall are respectively located at two opposite ends of the first cavity wall, and the second end of the cavity wall is located on a side of the cavity wall that is away from the second water outlet.

[0183] Along the rotation direction of the second water-pumping part, the first end of the cavity wall is the rearmost end of the first cavity wall in the rotation direction of the first cavity wall. When the second water-pumping cavity rotates and the first cavity wall rotates to the top, the first end of the cavity wall is the lowest end of the first cavity wall. The water in the second water-pumping cavity can pour downward under the action of gravity, so that the water can be discharged from the second drain outlet.

[0184] In the present application, along the rotation direction of the second water pumping part, the first end of the cavity wall can gradually extend forward in the rotation direction and extend to the second end of the cavity wall.

[0185] In this application, reference is made to Figure 10-Figure 14 The second cavity wall has a cavity wall third end 911121. The second cavity wall has a cavity wall fourth end 911122.

[0186] Along the axial direction of the second water pumping part, the third end of the cavity wall and the fourth end of the cavity wall are respectively located at two opposite ends of the second cavity wall, and the fourth end of the cavity wall is located on a side of the cavity wall that is away from the second water outlet from the third end of the cavity wall.

[0187] Along the rotation direction of the second water-pumping part, the third end of the cavity wall is the rearmost end of the second cavity wall in the rotation direction of the second cavity wall. When the second water-pumping cavity rotates and the second cavity wall rotates to the top, the third end of the cavity wall is the lowest end of the second cavity wall. The water in the second water-pumping cavity can pour downward under the action of gravity, so that the water can be discharged from the second drain outlet.

[0188] In the present application, along the rotation direction of the second water pumping part, the third end of the cavity wall can gradually extend forward in the rotation direction and extend to the fourth end of the cavity wall.

[0189] In this application, reference is made to Figure 10-Figure 14 The fourth water pumping mechanism may include a third dispersing portion 913. The third dispersing portion may be disposed in the second water pumping chamber to disperse the water in the second water pumping chamber.

[0190] The third breaking up part can cut off the water. The third breaking up part can interact with the second water pumping chamber to squeeze out the water.

[0191] In the present application, there may be multiple third breaking-up parts 913 .

[0192] In this application, reference is made to Figure 10-Figure 14 The third breaking up portion 913 may be a third breaking up column 9131 .

[0193] The third breaking up column 9131 may be disposed along the axial direction of the second water pumping part.

[0194] In the present application, under the action of the second water pumping part, the farther the water is from the rotation axis of the second water pumping part, the faster the water flows.

[0195] The more third dispersing columns are needed in places where the water flow is slow, the smaller the thickness of the third dispersing columns will be. The fewer the number of third dispersing columns are needed in places where the water flow is fast, the larger the thickness of the third dispersing columns will be.

[0196] In this application, reference is made to Figure 10-Figure 14 The vertical distance from the center of the third scattering column to the rotation axis of the second water pumping part is the seventh distance H7. The larger the seventh distance corresponding to the third scattering column, the larger the cross-sectional area where the center of the third scattering column is located, and the water can be scattered when the water flow rate is high.

[0197] In the present application, the third scattered column may be a circular column, a truncated cone column, a conical column, or a polygonal column.

[0198] In the present application, when the third scattering column is a cylinder, the central axis of the cylinder may be parallel to the rotation axis of the second water-splitting part.

[0199] In the present application, when the third breaking-up column is a cylinder, the cylinder can break up the water, break up the strands of water into several small strands, or impact the water to make the volume of the water smaller.

[0200] In the present application, under the action of the second water pumping part, the farther the water is from the rotation axis of the second water pumping part, the faster the water flows.

[0201] The more third dispersing columns are needed in places where the water flow is slow, the smaller the diameter of the third dispersing columns is. The fewer the number of third dispersing columns are needed in places where the water flow is fast, the larger the diameter of the third dispersing columns is.

[0202] In the present application, when the third scattering column is in a cylindrical position, the vertical distance from the central axis of the third scattering column to the rotation axis of the second water pumping part is the seventh distance. The larger the seventh distance corresponding to the third scattering column is, the larger the diameter of the third scattering column is.

[0203] Since the water flows at a high speed, if the diameter of the third dispersion column is not large enough, the water will not be easily divided. If the diameter of the third dispersion column is large, the water with a higher flow rate can be divided into multiple streams, and the dispersion effect is better.

[0204] In this application, reference is made to Figure 10-Figure 14 The second water pumping unit may include a second water wheel 9114. The second water wheel may be connected to a driving motor. The driving motor may drive the second water wheel to rotate.

[0224] In the present application, the second water guide plate is arranged on the outer side of the second section of the blade along the circumference of the second water wheel, and the second water guide plate is located on the side of the first section of the blade away from the second fixing plate.

[0225] In this application, reference is made to Figure 10-Figure 14A second flow guide cavity 9117 is formed between the second water pumping plate and the second fixed plate. The rear end of the second water guide plate is connected to the front end of the first section of the blade. The second water wheel divides the second flow guide cavity into a plurality of second water inlet cavities 91113.

[0228] In the present application, the second water retaining part can be arranged in a circumferential shape. The second water retaining part 912 can be arranged outside the second water pumping part along the circumference of the second water pumping part, and the second water pumping part is arranged inside the second water retaining part to block the water thrown out by the second water pumping part.

[0229] In this application, reference is made to Figure 15-16 , the second water retaining portion may include a first water retaining plate 9121.

[0230] In the present application, the first water baffle 9121 can be arranged on the outer side of the second water pumping part along the circumference of the second water pumping part, so as to block the water thrown out by the second water pumping part and guide it into the liquid storage chamber.

The second water guide ring may be arranged around the outer side of the spiral blade along the circumference of the water pumping screw. The second water guide ring and the water pumping screw define a conveying cavity 924 located between the second water guide ring and the water pumping screw.

[0254] In the present application, the third water outlet may be directed toward the outdoor heat exchanger.

[0255] In the present application, the driving motor drives the screw shaft to rotate and the spiral blades to rotate around the rotating axis of the screw shaft so that the water in the liquid storage chamber flows along the delivery chamber to the third water outlet and is discharged from the third water outlet and then hits the outdoor heat exchanger.

[0256] During cooling, the temperature of the outdoor heat exchanger is relatively high. A water-pumping screw and a second water-conducting ring are provided. The driving motor can be used to drive the screw shaft to rotate and the spiral blades to rotate around the rotating axis of the screw shaft, so that the water in the liquid storage chamber flows along the conveying chamber to the third water outlet and is discharged from the third water outlet and then hits the outdoor heat exchanger.

[0259] A section of the spiral blade close to the outdoor heat exchanger is arranged outside the liquid storage chamber so that the third water outlet is located outside the liquid storage chamber, which can avoid the liquid storage part blocking the third water outlet, ensure that the water pumped by the fifth water pumping mechanism can be pumped onto the outdoor heat exchanger, and improve the working efficiency of the fifth water pumping mechanism.
