[0002] Existing complete air conditioners, such as elevator air conditioners, use axial flow fan blades, and a water pump is provided outside the axial flow fan blades to pump condensed water to the condenser.

[0003] However, in the prior art, the water-pumping ring arranged around the axial flow fan blade has a small contact area with the condensed water, the water pumping is insufficient, and the spraying effect of the condensed water on the condenser is poor; moreover, the conventional installation method of the axial flow fan blade is a side-air outlet installation. During operation, the condensed water is introduced from the evaporator side. In addition to pumping the condensed water toward the condenser, the fan blade also pumps the condensed water toward the side of the fan blade, and this part of the condensed water on the side is not effectively utilized. At the same time, when there is a gap in the shell, it is easy to splash out of the fuselage, posing a quality risk. Summary of the Invention

DETAILED DESCRIPTION

[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs.

[0026] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0027] The present invention provides a centrifugal fan blade, please refer to Figure 1 , including: a centrifugal fan blade body 10, the centrifugal fan blade body 10 has a first end and a second end arranged in sequence along its axial extension direction; a water-beating rib 11, the water-beating rib 11 is protrudingly arranged on the centrifugal fan blade body 10, and the water-beating rib 11 extends in the direction from the first end to the second end of the centrifugal fan blade body 10.

[0028] The centrifugal fan blade of the present invention includes a centrifugal fan blade body 10 and a water-pumping rib 11. The water-pumping rib 11 is protrudingly arranged on the centrifugal fan blade body 10, and the water-pumping rib 11 extends in the direction from the first end to the second end of the centrifugal fan blade body 10; when the centrifugal fan blade rotates, the water-pumping rib 11 on the centrifugal fan blade contacts the condensed water below it. Since the water-pumping rib 11 extends between the first end and the second end of the centrifugal fan blade body 10, the contact area between the water-pumping rib 11 and the condensed water is large, thereby achieving the effect of sufficient water pumping, so that the condensed water is fully sprayed on the condenser, solving the problem that the condensed water cannot be fully sprayed on the condenser due to insufficient water pumping of the axial flow fan blade.

[0029] Specifically, the centrifugal fan blade includes at least 6 water-pumping ribs 11. Such an arrangement can ensure that the centrifugal fan blade fully pumps water.

[0030] In this embodiment, the centrifugal fan blade includes a plurality of water-pumping ribs 11, which are spaced apart along the circumference of the centrifugal fan body 10. This further increases the contact area between the water-pumping ribs 11 and the condensed water, thereby achieving a sufficient water-pumping effect. Furthermore, the plurality of water-pumping ribs 11 are spaced apart along the circumference of the centrifugal fan body 10. When condensed water approaches the centrifugal fan blade from various angles, it is pushed away from the centrifugal fan blade by the plurality of water-pumping ribs 11, allowing more condensed water to come into contact with the water-pumping ribs 11, ensuring sufficient water-pumping and allowing the condensed water to fully spray the condenser.

[0031] In this embodiment, if Figure 1 As shown, the water-injecting rib 11 extends from the first end of the centrifugal fan body 10 to the second end of the centrifugal fan body 10 .

[0032] In specific implementation, such a setting ensures that the contact area between the water-pumping ribs 11 and the condensed water is large enough to achieve a sufficient water-pumping effect.

[0033] Specifically, the centrifugal fan blade body 10 is a cylindrical frame with a hollow interior. During the rotation of the centrifugal fan blade, the condensed water pumped into the interior of the centrifugal fan blade by the water-pumping ribs 11 will pass through the internal space and contact with the remaining water-pumping ribs 11, thereby also achieving the effect of sufficient water pumping.

[0034] In this embodiment, the water rib 11 is a strip-shaped structure, which is a straight strip structure or an arc-shaped strip structure.

[0035] Specifically, when the water-pumping ribs 11 are of an arc-shaped structure, the contact area between the water-pumping ribs 11 and the condensed water is larger than that of the water-pumping ribs 11 of a straight structure, and the water-pumping ribs 11 are more suitable for water-pumping operations.

[0036] Specifically, the cross section of the water rib 11 perpendicular to its extension direction is rectangular or trapezoidal. It should be noted that the cross section of the water rib 11 perpendicular to its extension direction can also be other shapes.

[0037] In this embodiment, the centrifugal fan body 10 and the plurality of water-injecting ribs 11 are integrally formed. This design reduces the steps of connecting and matching the centrifugal fan body 10 and the plurality of water-injecting ribs 11, thereby increasing the overall strength of the centrifugal fan blade.

[0038] Specifically, one-piece molding means that the parts are not divided and are directly cast.

[0039] The present invention also provides an air conditioner, please refer to Figures 2 to 4, including a shell 20 and a middle partition 30. The middle partition 30 divides the shell 20 into a first cavity 21 and a second cavity 22. A first fan blade 40 and an evaporator 50 are provided in the first cavity 21, and a second fan blade 60 and a condenser 70 are provided in the second cavity 22. The first fan blade 40 and the second fan blade 60 are both the centrifugal fan blades in the above embodiment.

[0040] Specifically, if Figure 2 As shown, the first fan blade 40 , the evaporator 50 , the second fan blade 60 and the condenser 70 are sequentially arranged in the housing 20 .

[0041] During specific implementation, the first fan blade 40 and the second fan blade 60 respectively perform water pumping operations in the first cavity 21 and the second cavity 22 to achieve a heat exchange effect inside the air conditioner casing.

[0042] In this embodiment, the air conditioner also includes: a water diversion plate 80, located above the evaporator 50 and the condenser 70; the water diversion plate 80 is inclined relative to the horizontal plane, and the side of the water diversion plate 80 below the condenser 70 is lower than the side of the water diversion plate 80 below the evaporator 50.

[0043] During specific implementation, the water guide plate 80 is located above the evaporator 50 and the condenser 70 so that when the first fan blade 40 and the second fan blade 60 perform a water pumping operation, the condensed water pumped upward can condense on the water guide plate 80; and the water guide plate 80 is tilted downward in the direction from the evaporator 50 to the condenser 70, and the condensed water on the water guide plate 80 flows along its tilted direction to its lower point, falls into the second cavity 22, and sprays the condenser 70 in the second cavity 22, thereby increasing the utilization rate of the condensed water.

[0044] Specifically, the water guide plate 80 is located in the first cavity 21 and the second cavity 22 ; or, the water guide plate 80 is located on the top of the first cavity 21 and the second cavity 22 .

[0045] In this embodiment, the air conditioner also includes: a water receiving pan 90, located below the evaporator 50 and the condenser 70, the water receiving pan 90 is inclined relative to the horizontal plane, and the side of the water receiving pan 90 below the condenser 70 is lower than the side of the water receiving pan 90 below the evaporator 50; wherein, the bottom of the middle partition 30 is connected to the water receiving pan 90, and the middle partition 30 is provided with an opening for connecting the first cavity 21 and the second cavity 22, and the opening extends from the bottom of the middle partition 30 toward the top of the middle partition 30.

[0046] During specific implementation, since the water receiving tray 90 is tilted downward in the direction from the evaporator 50 to the condenser 70, and an opening for connecting the first cavity 21 and the second cavity 22 is provided on the middle partition 30, the condensed water generated by the evaporator in the first cavity 21 flows along the downward tilt of the water receiving tray 90. After passing through the opening, the condensed water enters the second cavity 22, so that the second fan blade 60 performs a water pumping operation on the condensed water in the second cavity 22, so that the condensed water sprays the condenser.

[0047] Specifically, if Figure 2 As shown, the water receiving tray 90 is square, and the middle partition 30, the first fan blade 40, the evaporator 50, the second fan blade 60, the condenser 70 and the water guide plate 80 are all within the load-bearing range of the water receiving tray 90. This arrangement ensures that when the first fan blade 40 and the second fan blade 60 are performing the water pumping operation, the condensed water will not leave the range of the water receiving tray 90, and the condensed water that slides down from the evaporator 50, the condenser 70 and the water guide plate 80 will not leave the range of the water receiving tray 90.

[0048] Optionally, the water receiving tray 90 is tilted 15 degrees relative to the horizontal plane.

[0049] In this embodiment, the air conditioner further includes a driving member 100 and a rotating shaft 110. The driving member 100 is drivingly connected to the rotating shaft 110, and the first fan blade 40 and the second fan blade 60 are both connected to the rotating shaft 110. The rotating shaft 110 passes through the condenser 70, the evaporator 50, and the middle partition 30. This arrangement can optimize the spatial layout within the housing 20 and reduce the space occupied within the housing 20.

[0050] During specific implementation, the driving member 100 drives the first fan blade 40 and the second fan blade 60 to rotate via the rotating shaft 110 to achieve the water pumping operation of the first fan blade 40 and the second fan blade 60 .

[0051] Optionally, the driver 100 is disposed in the second cavity 22, and the driver 100 and the second fan blade 60 are disposed on opposite sides of the condenser 70; the first fan blade 40 and the middle partition 30 are disposed on opposite sides of the evaporator 50. This arrangement can further optimize the spatial layout within the housing 20 and reduce the space occupied within the housing 20.

[0052] Specifically, the driving member 100 is a driving motor.

[0053] Specifically, the air conditioner further includes a mounting bracket, which is disposed in the housing 20 , and the driving member 100 is mounted on the mounting bracket.

[0054] In this embodiment, an atomizer 120 is provided in the evaporator 50 and / or the condenser 70. The atomizer 120 in the evaporator 50 can atomize the condensed water so that it can enter the indoor environment with the air for humidification. The condensed water contacts the atomizer 120 of the condenser 70 and atomizes and dissipates, contacting the second fin 71 and the second pipe 72 of the condenser, further enhancing the heat exchange effect.

[0055] Optionally, the nebulizer 120 is an ultrasonic nebulizer.

[0056] Optionally, at least two atomizers 120 are provided in the evaporator 50 ; at least two atomizers 120 are provided in the condenser 70 .

[0057] In this embodiment, an electric heater is provided in the evaporator 50 and / or the condenser 70. The electric heater in the evaporator 50 can provide auxiliary heating for the air when the air conditioner is in heating mode; and the electric heater in the condenser 70 can defrost and remove snow from the condenser 70 when the air conditioner is operating in winter.

[0058] Specifically, if Figure 3 As shown, the evaporator 50 includes a plurality of first fins 51 and a plurality of first pipes 52; Figure 4 As shown, the condenser 70 includes a plurality of second fins 71 and a plurality of second pipes 72. The first fins 51, the first pipes 52, the second fins 71 and the second pipes 72 are in contact with the water vapor converted by the atomizer 120, further enhancing the humidification effect and the heat exchange effect.

[0059] During the specific implementation of this application: after the air conditioner is started, the evaporator 50 generates condensed water, which falls into the water receiving tray 90. During the process, part of the condensed water contacts the atomizer 120 of the evaporator 50 and is atomized to enter the indoor environment for humidification. The remaining condensed water that falls into the water receiving tray 90 flows into the bottom of the condenser 70 through the middle opening under the action of gravity. At this time, the driving part 100 continues to operate, and the first fan blade 40 and the second fan blade 60 are driven, wherein the second fan blade 60 rotates at the lower part of the water receiving tray 90 and uses the water-pumping rib 11 to pump water. The condensed water is pumped toward the condenser 70 and the side of the second fan blade 60. The condensed water that is pumped upwards falls back along the water guide plate 80 to the upper side of the condenser 70 and flows down, thereby increasing the utilization rate of the condensed water. At the same time, the condensed water contacts the atomizer 120 of the condenser 70 and is atomized and dissipated, and contacts the second fin 71 and the second pipe 72 of the condenser, further increasing the heat exchange effect.

[0060] The present application has the following beneficial effects: condensed water is further utilized on the evaporator 50 and the condenser 70; and a single motor is used to simultaneously drive the first fan blade 40 and the second fan blade 60.

[0061] The present application has the following innovations: water is pumped by a centrifugal fan blade structure; part of the condensed water pumped to the peripheral side can be further guided to spray to the condenser 70; the condenser 70 and the evaporator 50 are respectively equipped with built-in ultrasonic atomizers 120 to enhance outdoor heat exchange and indoor humidification.

[0062] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0063] The centrifugal fan blade of the present invention includes a centrifugal fan blade body 10 and a water-pumping rib 11. The water-pumping rib 11 is protrudingly arranged on the centrifugal fan blade body 10, and the water-pumping rib 11 extends in the direction from the first end to the second end of the centrifugal fan blade body 10; when the centrifugal fan blade rotates, the water-pumping rib 11 on the centrifugal fan blade contacts the condensed water below it. Since the water-pumping rib 11 extends between the first end and the second end of the centrifugal fan blade body 10, the contact area between the water-pumping rib 11 and the condensed water is large, thereby achieving the effect of sufficient water pumping, so that the condensed water is fully sprayed on the condenser, solving the problem that the condensed water cannot be fully sprayed on the condenser due to insufficient water pumping of the axial flow fan blade.
