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

[0008] The utility model aims to solve one of the technical problems in the related art at least to a certain extent.

[0009] To this end, according to an embodiment of the present disclosure, an air conditioner outdoor unit is proposed, comprising:

[0010] An outdoor housing is formed with an outdoor air inlet and an outdoor air outlet, and an outdoor accommodating cavity is formed inside the outdoor housing and is connected with the outdoor air inlet and the outdoor air outlet;

[0011] An outdoor heat exchanger is arranged in the outdoor accommodation chamber;

[0012] An outdoor fan is arranged in the outdoor accommodating chamber and is located on a side of the outdoor heat exchanger away from the outdoor air inlet; the motor of the outdoor fan drives the outdoor fan to rotate;

[0013] A liquid storage part is arranged on a side of the outdoor fan away from the outdoor air inlet, a liquid storage cavity is formed in the liquid storage part to store water discharged from the indoor unit of the air conditioner, and a liquid storage cavity opening is arranged at the top of the liquid storage part to communicate with the liquid storage cavity;

[0014] Drive motor;

[0015] The second water pumping mechanism is partially inserted into the liquid storage cavity through the opening of the liquid storage cavity and includes:

[0016] a first water wheel connected to the driving motor and comprising a plurality of first blades, wherein the driving motor drives the first water wheel to rotate, and the plurality of first blades are arranged at intervals around a rotating shaft of the first water wheel;

[0017] A first water retaining ring is arranged around the outer side of the first water wheel along the circumference of the first water wheel and has a first water outlet formed at one side end thereof; the first blade is located in the first water retaining ring;

[0023] The water discharged from the first water outlet is set to hit the outdoor heat exchanger. During cooling, the temperature of the outdoor heat exchanger is relatively high. The water hitting the outdoor heat exchanger is evaporated by relying on the high temperature of the outdoor heat exchanger. This can prevent the water in the liquid storage part from overflowing onto the bottom plate of the air-conditioning outdoor unit without draining the water outward, and prevent water from leaking from the air-conditioning outdoor unit to cause water leakage of the air-conditioning outdoor unit, and prevent water from dripping onto users to cause poor user experience, and prevent water from dripping onto the floor or wall to affect the floor and wall, and avoid user complaints. In addition, the water can cool the outdoor heat exchanger and improve the heat exchange effect of the outdoor heat exchanger. The first water outlet is set to face the outdoor heat exchanger, which can prevent the water pumped by the second water pumping mechanism from splashing and splashing onto other areas of the outdoor casing, and prevent water leakage of the air-conditioning outdoor unit.

[0024] By setting the first 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 first 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 first water outlet from splashing onto other areas of the outdoor unit casing, thereby avoiding water leakage of the air-conditioning outdoor unit.

The first fixing plate 892 may be disposed along the axial direction of the first water wheel at a side of the first blade away from the first water outlet. The first blade may be connected to the first fixing plate.

[0152] In this application, reference is made to Figure 6-Figure 7 The second water pumping mechanism may include a second scattering portion 894. The second scattering portion 894 may be connected to the first fixing plate. The second scattering portion 894 may be located on a side of the first fixing plate connected to the first blade.

[0153] In the present application, the driving motor drives the first water wheel to rotate so that the first blades lift and disperse the water in the liquid storage chamber and discharge the water from the first water outlet.

[0154] The driving motor drives the first water wheel to rotate so that the first blade can lift and disperse the water in the liquid storage chamber. The first blade can pump part of the water toward the first water outlet. Due to the rotation of the first water wheel, part of the water moves toward the first water retaining ring under the action of centrifugal force. The first water retaining ring changes the direction of the water so that the water is discharged from the first water outlet.

[0155] In the present application, the driving motor can drive the second scattering part to rotate around the rotating shaft of the first water wheel so that the second scattering part scatters the water stirred up by the first blades.

[0156] In this application, reference is made to Figure 8 The first water outlet may be directed toward the outdoor heat exchanger so that the water discharged from the first water outlet hits the outdoor heat exchanger.

[0157] The water discharged from the first water outlet is arranged to hit the outdoor heat exchanger. During cooling, the temperature of the outdoor heat exchanger is relatively high. The water hitting the outdoor heat exchanger is evaporated by relying on the high temperature of the outdoor heat exchanger. This can prevent the water in the liquid storage part from overflowing onto the bottom plate of the air-conditioning outdoor unit without discharging the water outward, and prevent water from leaking from the air-conditioning outdoor unit to cause water leakage of the air-conditioning outdoor unit, and prevent water from dripping onto users to cause poor user experience, and prevent water from dripping onto the floor or wall to affect the floor and wall, and avoid user complaints. In addition, the water can cool the outdoor heat exchanger and improve the heat exchange effect of the outdoor heat exchanger. The first water outlet is arranged to face the outdoor heat exchanger, so that the water pumped by the second water pumping mechanism can be prevented from splashing and splashing onto other areas of the outdoor casing, thereby preventing water leakage of the air-conditioning outdoor unit.

[0158] In the present application, when the first water outlet is directed toward the outdoor heat exchanger, the first water outlet may be directed toward the first-stage outdoor heat exchanger.

[0159] In this application, reference is made to Fig. 9 The first water outlet may be oriented toward the outdoor air outlet so that water discharged from the first water outlet flows out of the outdoor containing chamber through the outdoor air outlet under the drive of the outdoor fan.

[0160] By setting the first 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 first 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 first water outlet from splashing onto other areas of the outdoor unit casing, thereby avoiding water leakage of the air-conditioning outdoor unit.

[0161] In the present application, when the first water outlet faces the outdoor heat exchanger, the driving motor may be connected to the first water wheel. The first fixing plate may be connected to the driving motor through the first water wheel.

[0162] In the present application, when the first water outlet faces the outdoor heat exchanger, the driving motor may be connected to the first fixing plate. The first water wheel may be connected to the driving motor through the first fixing plate.

[0163] In the present application, when the first water outlet faces the outdoor heat exchanger, the driving motor can be connected to both the first fixing plate and the first water wheel.

[0164] In the present application, when the first water outlet faces the outdoor air outlet, the driving motor can be connected to the first water wheel. The first fixing plate can be connected to the driving motor through the first water wheel.

[0165] In the present application, when the first water outlet faces the outdoor air outlet, the driving motor may be connected to the first fixing plate. The first water wheel may be connected to the driving motor through the first fixing plate.

[0166] In the present application, when the first water outlet faces the outdoor air outlet, the driving motor can be connected to both the first fixing plate and the first water wheel.

[0167] In the present application, the first water wheel can be an axial flow impeller, the first blade can be an axial flow blade, the first blade can pump up the water in the liquid storage chamber, the first blade can pump part of the water toward the first water outlet, and due to the rotation of the first water wheel, part of the water moves toward the first water retaining ring under the action of centrifugal force.

[0168] In the present application, the first hub may be connected to the first fixing plate. The first hub may be at least partially located on a side of the first fixing plate close to the first water outlet. The first hub may be connected to the driving motor.

[0169] In the present application, the first blade may include a first blade first end and a first blade second end that are arranged opposite to each other. The first blade first end is connected to the first fixing plate.

[0170] Along the rotation direction of the first hub, the first end of the first blade is located in front of the second end of the first blade in the rotation direction of the second end of the first blade, so that the first blade can guide the stirred water to one side of the first water outlet, so that the water flows out from the first water outlet.

[0171] In the present application, the first fixed plate can be located inside the first water retaining ring, which can prevent the water thrown up by the first fixed plate on both sides of the axial direction of the first water wheel rotating shaft from hitting the outside of the first water retaining ring, and avoid throwing water onto the top plate and side plates of the outdoor casing.

[0172] In this application, reference is made to Figure 6-Figure 7 The first fixing plate may include a first fixing surface 8921. The first blade is connected to the first fixing surface. The second breaking up portion is connected to the first fixing surface.

[0173] In the present application, the first fixed surface may be a circular surface. The diameter of the first fixed surface is the fifth diameter D5. The diameter of the outer contour of the first water wheel when rotating is the sixth diameter D6.

[0174] In the present application, D6 / D5≥the 23rd parameter value. The 23rd parameter value may be any value between 0.5 and 0.7. The 23rd parameter value may be 2 / 3. D6 / D5≥2 / 3. This can prevent the first water wheel from being too small compared to the first fixed surface, and can fully utilize the size of the first fixed surface so that enough water is pumped up.

[0175] In the present application, D6 / D5≤ parameter value twenty-four. The parameter value twenty-four may be any value between 0.75 and 0.85. The parameter value twenty-four may be 4 / 5. D6 / D5≤4 / 5. It is possible to prevent the first water wheel from being too large compared to the first fixed surface, and to leave enough space on the outer wheel of the first water wheel for setting the second dispersion portion, so that the water stirred up by the first water wheel can be sufficiently dispersed, and it is possible to prevent the water on the outdoor heat exchanger from being too concentrated, so that the outdoor heat exchanger cannot evaporate the water in time, and prevent the unevaporated water from flowing down from the outdoor heat exchanger, and prevent the water from flowing along the outdoor heat exchanger to the bottom plate of the air conditioner outdoor unit, and allow the air to be blown farther, so that the water is blown out of the outdoor air outlet conveniently, and prevent the water from dripping onto the bottom plate of the air conditioner outdoor unit during the blowing process.

[0176] In the present application, the first fixing plate may be located inside the first water retaining ring, and the maximum distance between the first fixing plate and the inner peripheral wall of the first water retaining ring is the third distance H3.

[0177] In the present application, the third distance H3≤the twenty-fifth parameter value. The twenty-fifth parameter value may be any value between 25 mm and 30 mm. The twenty-fifth parameter value may be 30 mm. The third distance H3≤30 mm. It is possible to prevent the gap between the first fixing plate and the inner peripheral wall of the first water retaining ring from being too large so that water flows out from the other end of the first water retaining ring, and to prevent water from hitting other structural parts and causing water leakage in the air conditioner outdoor unit.

[0178] In the present application, the first fixing plate may be located inside the first water retaining ring, and the minimum distance between the first fixing plate and the inner peripheral wall of the first water retaining ring is a fourth distance H4.

[0179] In the present application, the fourth distance H4 ≥ the twenty-sixth parameter value. The twenty-sixth parameter value may be any value between 0.1 mm and 5 mm. The twenty-sixth parameter value may be 0.1 mm. The fourth distance H4 ≥ 0.1 mm. It is possible to avoid the gap between the first fixed plate and the inner peripheral wall of the first water retaining ring being too small so that the first water retaining ring interferes with the first fixed plate, thereby ensuring the normal operation of the first fixed plate.

[0180] In the present application, 0.1mm≤H3≤30mm. This can prevent the gap between the first fixed plate and the inner circumferential wall of the first water retaining ring from being too small, causing the first water retaining ring to interfere with the first fixed plate, thereby ensuring the normal operation of the first fixed plate, and can prevent the gap between the first fixed plate and the inner circumferential wall of the first water retaining ring from being too large, causing water to flow out from the other end of the first water retaining ring, thereby preventing water from hitting other structural parts and causing water leakage in the air conditioner outdoor unit.

[0203] In the present application, among the plurality of second dispersing parts, at least part of the second dispersing parts surround the outer side of the first water wheel and can disperse the water between the first blades and the inner peripheral wall of the first water retaining ring.

[0204] The second breaking up part can cut off the water. The second breaking up part can squeeze out the water together with the first blade. The second breaking up part can squeeze out the water together with the inner peripheral wall of the first water retaining ring.

[0205] In the present application, among the plurality of second breaking-up parts, at least part of the second breaking-up parts are arranged between two adjacent first blades, and can break up the water between the two adjacent first blades.

[0206] The second breaking up part can cut off the water. The second breaking up part can squeeze out the water with the first blade.

[0207] In the present application, among the plurality of second breaking-up parts, some of the second breaking-up parts surround the outer side of the first water wheel, and some of the second breaking-up parts are arranged between two adjacent first blades.

[0208] In the present application, the second breaking up portion is the second breaking up column 8941 .

[0209] The second scattering column includes a first end and a second end that are arranged opposite to each other. The first end of the second scattering column is connected to the first fixing plate. The second end of the second scattering column is located on a side of the first end of the second scattering column that is away from the first fixing plate.

[0210] In the present application, the extension direction of the second scattering column may be parallel to the rotation axis of the first water wheel.

[0211] In the present application, under the action of the first water wheel, the farther the water is from the rotation axis of the first water wheel, the faster the water flows.

[0212] The more second dispersing columns are needed in places with slow water flow, the smaller the thickness of the second dispersing columns will be. The fewer the number of second dispersing columns are needed in places with fast water flow, the larger the thickness of the second dispersing columns will be.

[0213] In the present application, the vertical distance from the center of the second scattering column to the rotation axis of the first water wheel is the second distance H2. The larger the second distance corresponding to the second scattering column, the larger the cross-sectional area where the center of the second scattering column is located, and the water can be scattered when the water flow rate is high.

[0216] In the present application, when the second 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.

[0217] In the present application, under the action of the first water wheel, the farther the water is from the rotation axis of the first water wheel, the faster the water flows.

[0218] The more second scattering columns are needed in places with slow water flow, the smaller the diameter of the second scattering columns is. The fewer the number of second scattering columns are needed in places with fast water flow, the larger the diameter of the second scattering columns is.

[0219] In the present application, when the second scattering column is a cylinder, the vertical distance from the center axis of the second scattering column to the rotation axis of the first water wheel is the second distance. The larger the second distance corresponding to the second scattering column is, the larger the diameter of the second scattering column is.

[0220] Since the water flows at a high speed, if the diameter of the second dispersion column is not large enough, the water will not be easily divided. If the diameter of the second dispersion column is larger, the water with a higher flow rate can be divided into multiple streams, and the dispersion effect is better.
