[0002] The condensate produced by the evaporator of an air conditioner is usually collected in a condensate tray in the chassis. To prevent excessive overflow of condensate from the chassis, a water-discharging motor is usually installed inside the chassis. The water-discharging motor is fixed to the chassis and drives a flywheel to rotate, spraying the condensate onto the fins for evaporation, thereby cooling the condenser. However, in traditional water-discharging devices, the flywheel is fixed, resulting in a narrow splashing range of condensate and uneven heat dissipation from the condenser. Summary of the Invention

[0005] In some embodiments, the chassis has an insertion hole, and the water-spraying mechanism further includes an auxiliary bracket, the first motor is mounted on the auxiliary bracket, and the auxiliary bracket is provided with an insertion shaft that can be rotatably inserted into the insertion hole.

[0006] In some embodiments, the power mechanism includes a second motor, an eccentric wheel, and a connecting rod. The second motor is mounted on the chassis, the eccentric wheel is mounted on the output shaft of the second motor, and the two ends of the connecting rod are respectively hinged to the eccentric wheel and the auxiliary support.

[0007] In some embodiments, a snap-fit ​​is formed at the end of the insertion shaft away from the auxiliary bracket, and the snap-fit ​​engages with the chassis after the insertion shaft is inserted into the insertion hole.

[0008] In some embodiments, the insertion shaft includes a first insertion body and a second insertion body, which are spaced apart on the auxiliary support.

[0009] In some embodiments, the insertion shaft is located at the bottom of the auxiliary bracket, and the insertion hole is located below the auxiliary bracket.

[0010] In some embodiments, a first support body and a second support body are formed on the chassis, the first support body and the second support body are respectively located on two sides of the jack, and both the first support body and the second support body support the auxiliary bracket.

[0011] In some embodiments, a notch is formed on the chassis, the output shaft of the first motor passes through the notch, and the width of the notch gradually increases in the direction from the bottom of the notch to the top of the notch.

[0012] In some embodiments, a condenser is assembled in the chassis, the condenser includes a first heat exchange portion and a second heat exchange portion, and the water throwing wheel is further located between the first heat exchange portion and the second heat exchange portion.

[0013] The present invention further provides an air conditioner, comprising the water throwing device described above.

[0014] The present invention further provides a control method for an air conditioner, which is used for controlling the operation of the air conditioner described above, and the control method comprises: The air conditioner operates in a cooling mode; Acquiring the water level in the water collection tank and recording it as H; Controlling the start and stop of the first motor and the second motor and adjusting the rotational speed of the water throwing wheel according to the magnitude of H.

[0015] In some embodiments, when H < H1, the first motor and the second motor are controlled to stop; When H1 ≤ H < H2, the first motor and the second motor are controlled to start, and the rotational speed of the water throwing wheel is controlled to be V1; When H2 ≤ H < H3, the first motor and the second motor are controlled to start, the air humidity is acquired and recorded as RH, and the operating power of the compressor of the air conditioner and the rotational speed of the water throwing wheel are further controlled and adjusted according to the magnitude of RH; Wherein, H1 is a first set water level, H2 is a second set water level, H3 is a third set water level, and H1 < H2 < H3.

The temperature difference of the condenser is the maximum temperature difference between different parts of the condenser, and T1 is the first set temperature.

[0018] The water dispensing device, air conditioner, and control method provided by this invention have the following beneficial effects: Because the power mechanism can drive the water-spraying mechanism to swing back and forth on the chassis, the first motor drives the water-spraying wheel to rotate while swinging back and forth, so that the water-spraying wheel can swing back and forth to spray water. The back and forth swing of the water-spraying wheel breaks the limitation of the fixed angle of the traditional water-spraying flywheel, which significantly expands the range of condensate splashing, realizes the wide-area uniform heat dissipation of the condenser, and provides an energy-saving refrigeration and air conditioning equipment.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0024] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0025] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0026] See also Figures 1 to 9 As shown, according to an embodiment of the present invention, a water-spraying device is provided, including a power mechanism, a water-spraying mechanism, and a chassis 1. The water-spraying mechanism includes a first motor 2 and a water-spraying wheel 3, with the water-spraying wheel 3 mounted on the output shaft of the first motor 2. The chassis 1 has a water collection tank 4, and the water-spraying wheel 3 is at least partially located within the water collection tank 4. The power mechanism is capable of driving the water-spraying mechanism to swing back and forth on the chassis 1. The water collection tank 4 is used to collect condensate produced by the evaporator of an air conditioner, while the water-spraying wheel 3 is used to agitate the condensate collected in the water collection tank 4, causing it to splash onto the condenser 14 of the air conditioner.

[0027] In this technical solution, since the power mechanism can drive the water-spraying mechanism to swing back and forth on the chassis 1, the first motor 2 drives the water-spraying wheel 3 to rotate while swinging back and forth, so that the water-spraying wheel 3 can swing back and forth to spray water. The back and forth swing of the water-spraying wheel 3 breaks the limitation of the fixed angle water splashing of the traditional water-spraying flywheel, which significantly expands the range of condensate splashing, realizes the wide-area uniform heat dissipation of the condenser 14, and provides an energy-saving refrigeration and air conditioning equipment.

[0028] It should be noted that existing water-spraying modules only include a water-spraying motor and an impeller. The output shaft of the water-spraying motor is tilted towards the condenser, so that the water-spraying surface of the impeller is at a preset angle to the horizontal plane, spraying condensate onto the condenser fins at a specific angle. Although this design can ensure efficient discharge of condensate, increase the splash area, and improve heat dissipation uniformity, the tilted arrangement of the motor's output shaft causes the bearings to bear asymmetrical radial loads, which can easily accelerate wear and fatigue failure over long-term operation. Moreover, the spraying angle is fixed and preset, lacking a dynamic trajectory adjustment mechanism, and cannot adapt to the local heat island distribution of the condenser, easily resulting in blind spots and uneven heat dissipation coverage. The water-spraying wheel 3 in this application solves these problems.

[0029] See also Figure 1 , Figure 5 , Figure 6 and Figure 8 As shown, a socket 6 is formed on the chassis 1, and the water pumping mechanism also includes an auxiliary support 7. The first motor 2 is assembled on the auxiliary support 7, and a plug shaft 8 is provided on the auxiliary support 7. The plug shaft 8 can be rotatably inserted into the socket 6.

[0030] In this embodiment, because the insertion shaft 8 on the auxiliary bracket 7 can rotate within the insertion hole 6, the auxiliary bracket 7 can swing back and forth on the chassis 1 with the insertion shaft 8 as the axis. The first motor 2 is assembled on the auxiliary bracket 7, so the auxiliary bracket 7 can drive the first motor 2 to swing back and forth on the chassis 1, ultimately realizing the first motor 2 swinging back and forth on the chassis 1.

[0031] See also Figure 1 , Figure 2 and Figure 4 As shown, the power mechanism includes a second motor 5, an eccentric wheel 9, and a connecting rod 10. The second motor 5 is assembled on the chassis 1, the eccentric wheel 9 is assembled on the output shaft of the second motor 5, and the two ends of the connecting rod 10 are respectively hinged to the eccentric wheel 9 and the auxiliary support 7.

[0032] In this technical solution, when the second motor 5 drives the eccentric wheel 9 to rotate, the eccentric wheel 9 will cause the connecting rod 10 to continuously change position during rotation. The connecting rod 10, in turn, will cause the auxiliary support 7 to swing back and forth on the chassis 1. That is, through this simple structural combination of the eccentric wheel 9 and the connecting rod 10, the second motor 5 indirectly drives the auxiliary support 7 to swing back and forth on the chassis 1. It should be noted that the power mechanism can also be a hydraulic cylinder, oil cylinder, etc. The extension and retraction end of the hydraulic cylinder or oil cylinder is hinged to the side of the auxiliary support 7. The extension and retraction of the hydraulic cylinder or oil cylinder can also achieve the swinging back and forth of the auxiliary support 7 on the chassis 1 around the insertion shaft 8.

[0033] See Figure 4As shown, a condenser 14 is assembled inside the chassis 1. The condenser 14 includes a first heat exchange section 141 and a second heat exchange section 142. The water agitator 3 is located between the first heat exchange section 141 and the second heat exchange section 142. This design ensures that the water agitator 3 can pump the condensate onto the fins of the condenser 14 for evaporation as much as possible, and avoids the condensate splashing onto other components and causing a short circuit. It should be noted that the angular offset range of the water agitator 3 can be limited by specifying the size of the eccentric wheel 9, thus preventing the water agitator 3 from hitting the condenser 14.

[0034] See also Figure 5 , Figure 6 and Figure 8 As shown, a snap-fit ​​is formed at the end of the insertion shaft 8 away from the auxiliary bracket 7. After the insertion shaft 8 is inserted into the insertion hole 6, the snap-fit ​​engages with the chassis 1.

[0035] In this embodiment, the snap-fit ​​between the buckle and the chassis 1 does not affect the rotation of the insert shaft 8 in the insert hole 6, and can also enhance the assembly firmness between the auxiliary bracket 7 and the chassis 1, thereby ensuring the assembly firmness between the water-spraying mechanism composed of the auxiliary bracket 7, the first motor 2 and the water-spraying wheel 3 and the chassis 1.

[0036] See Figure 8 As shown, the insertion shaft 8 includes a first insertion body 81 and a second insertion body 82, which are spaced apart on the auxiliary support 7.

[0037] In this technical solution, because the first insert 81 and the second insert 82 are distributed at intervals on the auxiliary bracket 7, the first insert 81 and the second insert 82 are easily brought together after being subjected to force, which makes the diameter of the insert shaft 8 composed of the two smaller. When the insert shaft 8 with a smaller diameter is inserted into the insert hole 6, it is easier for the buckle to enter the insert hole 6, thereby making it easier to achieve the snap-fit ​​between the buckle and the chassis 1.

[0038] Preferably, the insertion shaft 8 is located at the bottom of the auxiliary support 7, and the insertion hole 6 is located below the auxiliary support 7. This allows the chassis 1 to support the water-spraying mechanism composed of the auxiliary support 7, the first motor 2, and the water-spraying wheel 3 from bottom to top, and ensures the stability of the support for the water-spraying mechanism, thereby ensuring the working stability of the water-spraying mechanism during the back-and-forth swinging process.

[0039] See also Figure 1 , Figure 5 and Figure 6 As shown, a first support body 11 and a second support body 12 are formed on the chassis 1. The first support body 11 and the second support body 12 are located on both sides of the socket 6, and both the first support body 11 and the second support body 12 support the auxiliary bracket 7.

[0040] In this embodiment, the first support 11 and the second support 12 are located on both sides of the insertion hole 6 and support the auxiliary bracket 7. This ensures the stability of the water-spraying mechanism composed of the auxiliary bracket 7, the first motor 2 and the water-spraying wheel 3 on the chassis 1, and also ensures the stability of the water-spraying mechanism during the back-and-forth swinging process on the chassis 1.

[0041] See also Figures 1 to 3 , Figure 5 and Figure 7 As shown, a notch 13 is formed on the chassis 1, and the output shaft of the first motor 2 passes through the notch 13. The width of the notch 13 gradually increases from the bottom to the top of the notch 13.

[0042] In this technical solution, the width of the notch 13 gradually increases from the bottom to the top of the notch 13, making the notch 13 an outward-expanding notch. This outward-expanding notch satisfies the left-right back-and-forth swinging requirements of the output shaft of the first motor 2, thereby satisfying the left-right back-and-forth swinging requirements of the waterwheel 3.

[0043] The present invention also provides an air conditioner including the aforementioned water pumping device.

[0044] The present invention also provides a control method for an air conditioner, used to control the operation of the aforementioned air conditioner, the control method comprising: The air conditioner is running in cooling mode. The water level in the water collection tank 4 is recorded as H; The starting and stopping of the first motor 2 and the second motor 5, as well as the speed of the water-driving wheel 3, are controlled according to the value of H.

[0045] In this embodiment, since the water level in the water collection tank 4 determines the amount of condensate collected in the water collection tank 4, and the amount of condensate collected in the water collection tank 4 determines whether the water jet 3 swings to spray water and the rotation speed when spraying water, it is necessary to control the start and stop of the first motor 2 and the second motor 5 and control and adjust the rotation speed of the water jet 3 according to the size of H.

[0046] In one specific implementation, the water collection tank 4 is set with three water levels, namely the first set water level H1, the second set water level H2, and the third set water level H3, where H1 < H2 < H3, 6mm ≤ H1 ≤ 7mm, 8mm ≤ H2 ≤ 12mm, and 15mm ≤ H3 ≤ 16mm; the water impeller 3 is set with two set rotational speeds, namely V1 and V2, where V1 < V2, V1 is 860±50r / min, and V2 is 960±50r / min.

[0047] When H is less than H1, the current water level is too shallow to reach the working height of the water slinging wheel 3, so the water slinging device does not operate. Both the first motor 2 and the second motor 5 are controlled to stop, the rotation speed of the water slinging wheel 3 is zero, and the air conditioner continues to operate while maintaining the current state, waiting for the water level to rise to the trigger threshold.

[0048] When H1 ≤ H < H2, the water level has reached the working height of the water slinging wheel 3, but has not yet reached the optimal water slinging depth. Therefore, both the first motor 2 and the second motor 5 are controlled to start up, the rotation speed of the water slinging wheel 3 is controlled to be V1, and the water slinging wheel 3 swings left and right to realize wide-area uniform water splashing under a small water volume, ensuring that the entire condenser 14 obtains uniform heat dissipation.

[0049] When H2≤H<H3, although the water level has reached the optimal water depth range, and both the first motor 2 and the second motor 5 are started to make the water pump 3 pump water, it is still necessary to perform combined regulation by monitoring the air humidity RH and the temperature difference ΔT of the condenser 14 to avoid shutdown due to full water. The temperature difference of the condenser 14 is the maximum temperature difference between different parts of the condenser 14. Specifically, two set humidity levels are set: a first set humidity RH1 and a second set humidity RH2, where RH1 < RH2, RH1 is 75%, and RH2 is 90%. The compressor has three operating power levels: W1, W, and W2, where W1 < W < W2. It should be noted that the specific values ​​of W1, W, and W2 depend on the compressor's performance, and this application does not specify them here. To obtain the temperature difference of the condenser 14, temperature sensors can be evenly arranged on the condenser 14, and the temperature difference can be obtained by comparing the temperatures of each sensor, thus identifying the high-temperature zone. When RH≥RH2, it indicates high air humidity. The air conditioning system predicts that a lot of condensate will be generated in the next hour. Therefore, the speed of the water pump 3 is increased to V2 to swing left and right, significantly increasing the water volume and accelerating the consumption of condensate. A large amount of water is evenly sprayed onto the condenser 14 to maximize the overall heat dissipation efficiency. At the same time, the operating power of the compressor is actively reduced to W1 to reduce the generation of condensate. When RH1<RH<RH2, it indicates low air humidity. The air conditioning system predicts that the dehumidification efficiency will decrease in the next hour, and less condensate will be generated. Therefore, the water pump 3 uses a low speed V1 to reduce the water volume. The reduction in water volume causes the heat dissipation rate of the condenser 14 to decrease. To avoid local overheating, when △T>T1, the second motor 5 is stopped, the left and right swing of the water pump 3 is canceled and fixed at a set angle, so that the water flow is directed at the hottest area of ​​the condenser 14, performing fixed-point heat dissipation for about 10 seconds. Here, T1 is the first set temperature, specifically 10℃. Understandably, because the humidity is low at this time, the compressor's operating power needs to be increased to W2 to accelerate condensate formation. When RH1 < RH < RH2, it indicates that the air humidity is at an intermediate level. To ensure that the increase and consumption of condensate are balanced, the water impeller 3 operates at a low speed V1 and oscillates left and right to maintain stable heat dissipation of the condenser 14. The compressor's operating power is adjusted to W, and the air conditioning system operates stably. It should be noted that the introduced feedforward prediction mechanism based on air humidity RH changes the passive waiting situation of waiting for the water to fill up, while controlling the condensate "production-consumption" balance, significantly reducing the frequency of shutdown when the water is full.

[0050] When H≥H3, it indicates that the condensate water is full, and there is a risk of water overflowing and damaging electrical components. At this time, the system triggers a forced safety mechanism: shutdown when the water is full.

[0051] Understandably, the above control logic can improve the system's operational stability and electrical safety. At the same time, it can adaptively find the optimal balance between cooling performance, heat dissipation efficiency, and safety protection under different operating conditions, greatly improving the overall reliability of the air conditioner.

Figure 9 In the middle, the water-spraying flywheel is the water-spraying wheel 3, the water-spraying device swings left and right, the water-spraying wheel 3 swings left and right, and the water-spraying device is aimed at the high-temperature position, that is, the water flow sprayed by the water-spraying wheel 3 is aimed at the high-temperature area with the highest temperature in the condenser 14.

[0053] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.
