Abstract
Description
Technical Field
[0001] This invention relates to the field of air conditioning technology, and in particular to a water-spraying structure, a water-spraying device, and a portable air conditioner. Background Technology
[0002] Water-lifting structures are commonly used in portable air conditioners to lift water stored in the chassis onto the condenser fins, thereby reducing the amount of water in the chassis.
[0003] Currently used water pump motors mostly have flat blades, which result in poor water pumping performance and have the following problems:
[0004] 1. The water pump motor is prone to burnout: The flat blades bear concentrated and undistributed force, which increases the motor torque. Alternatively, when the portable air conditioner operates in harsh environments, dirt can easily accumulate on the water pump blades, which will further increase the torque of the water pump motor and thus burn out the motor.
[0005] 2. Small water volume: The contact area between water and the flywheel is small, resulting in a small water volume.
[0006] 3. High energy consumption: When the water jet is in contact with the water, the force is concentrated, resulting in high energy consumption;
[0007] 4. Poor water directionality: It can easily cause water to splash onto electrical components and the casing, creating a safety hazard and potentially overflowing from the chassis. Summary of the Invention
[0008] In view of this, the present invention provides a water-spraying structure, a water-spraying device, and a portable air conditioner, which at least solve the technical problems of high water-spraying resistance and complex cleaning of the water-spraying structure in the prior art, specifically:
[0009] In a first aspect, the present invention provides a water-spraying structure, comprising:
[0010] The base has a circular structure, and a mounting structure for drive connection is provided at the center of the base.
[0011] The blade includes a water-spraying surface and a backwater surface, and the blade is provided with a through hole, the two ends of which are located on the water-spraying surface and the backwater surface, respectively.
[0012] The blades extend outward from the edge of the substrate and are arranged in multiples along the circumference of the substrate.
[0013] Alternatively, the through hole is provided at an angle.
[0014] The through hole is located at the port on the water-spraying surface, close to the substrate.
[0015] The through hole is located on the backwater surface with its port positioned away from the substrate.
[0016] Alternatively, multiple water-beating grooves are formed on the water-beating surface of the blade, making the water-beating surface a non-planar structure.
[0017] Alternatively, multiple water-spraying troughs may be arranged side by side and extend along the length of the blades.
[0018] Alternatively, two water troughs may be provided.
[0019] Alternatively, the blade may be constructed in an arc shape, with the concave surface of the arc shape forming the water-beating surface and the convex surface of the arc shape forming the backwater surface.
[0020] Alternatively, the water-spraying structure may further include an outer ring structure, wherein the portion of the blade furthest from the base is fixedly connected to the outer ring structure.
[0021] Alternatively, the outer ring structure is provided with water passage holes, which are located between two adjacent blades.
[0022] Secondly, the present invention provides a water-spraying device, comprising a drive motor and the water-spraying structure as described in any one of claims 1-8.

[0026] The aforementioned water-spraying structure, or the aforementioned water-spraying device.
[0027] This invention utilizes through-holes in the blades to allow water to flow from the water-applying surface to the back surface, thus reducing the force exerted on the blades and decreasing the stress on them. Furthermore, the through-holes also allow airflow to flow back to the water-applying surface when the water-applying structure reverses, thereby achieving self-cleaning of the blades.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0037] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.
[0038] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.
[0039] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.
[0040] This invention reduces the force on the blades by creating through holes in the water-spraying structure, allowing some of the force applied by the water to be unloaded during water spraying. Furthermore, the through holes allow airflow to pass through and reach the water-spraying surface during the reversing process, blowing away foreign objects and thus cleaning the water-spraying surface.
[0041] Specifically,
[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the present invention provides a water-spraying structure, comprising:
[0043] The base 1 has a circular structure, such as a circular plate structure with a certain thickness. A mounting structure for drive connection is set at the center of the base 1. The mounting structure can be a mounting hole or a mounting shaft, and the center of the mounting hole and the mounting shaft coincides with the center of the base 1.
[0044] The blade 2 includes a water-spraying surface 21 and a back-water-spraying surface 22. A through hole 23 is provided on the blade 2, with the two ends of the through hole 23 located on the water-spraying surface 21 and the back-water-spraying surface 22, respectively.
[0045] The blades 2 are disposed on the side wall of the base 1, extending outward from the edge of the base 1, and multiple blades 2 are disposed along the circumference of the base 1. Preferably, the multiple blades 2 are evenly distributed along the circumference of the base 1.
[0046] Preferably, the substrate 1 and the blade 2 are constructed as a single unit, for example, they can be integrally formed by injection molding or other methods.
[0047] Preferably, the through hole 23 is arranged at an angle, that is, the port of the through hole 23 on the water-spraying surface 21 is located close to the base 1, and the port of the through hole 23 on the back water-spraying surface 22 is located away from the base 1. The through hole 23 is arranged along the length direction of the blade 2 and is inclined relative to the blade 2, so that the two ports of the through hole 23 can be located on the water-spraying surface 21 and the back water-spraying surface 22 respectively. The arrangement and inclination of the through hole 23 can reduce the amount of water flowing into the through hole 23 during water spraying. Even if a small amount of water flows into the through hole 23 and then flows out, it flows away from the base 1, which has the effect of dispersing water.
[0048] like Figure 5As shown, multiple water-beating grooves 24, such as two or more, are formed on the water-beating surface 21 of the blade 2, making the water-beating surface 21 a non-planar structure. The water-beating grooves 24 are arranged along the length direction of the blade 2, thereby guiding the water to flow along the water-beating grooves 24 and towards the end of the blade 2 away from the base 1. On the other hand, the arrangement of the water-beating grooves 24 can also decompose the force acting on the blade 2, i.e., F1 = F * cos70.61°, reducing the force borne by the blade. Preferably, the angle between F1 and F can be 45°-75°, and the smaller the value of F1, the better.
[0049] Preferably, in one specific embodiment, two water jets 24 are provided. The cross-section of each water jet 24 is approximately V-shaped, and the two water jets 24 are arranged side by side so that the water jet surface 21 is constructed into a roughly W-shaped curved surface. The arrangement of the water jets 24 can, on the one hand, guide the water flow; on the other hand, the intersection of the two water jets 24 and the interior of the water jets 24 are constructed as smooth curved surfaces, thereby decomposing the force of water acting on the blade 2 and reducing the stress on the blade 2.
[0050] It is easy to imagine that when the width of the blade 2 is relatively large, more water-spraying troughs 24 can be set up side by side.
[0051] The blade 2 is preferably constructed as an arc-shaped structure. The concave surface of the arc-shaped structure forms the water-spraying surface 21, and the convex surface of the arc-shaped structure forms the back-water surface 22. When the blade 2 with the arc-shaped structure sprays water, the concave surface can spray water to increase the water volume and improve the water spraying efficiency.
[0052] Preferably, the water-spraying structure further includes an outer ring structure 3, which is a circular ring structure. The portion of the blade 2 away from the base 1 is fixedly connected to the outer ring structure 3. For example, in one specific embodiment, the end of the blade 2 away from the base 1 is fixed to the outer ring structure 3. The outer ring structure 3 can improve the strength of the blade 2, enabling it to withstand greater forces and achieve higher reliability.
[0053] Furthermore, the outer ring structure 3 is provided with a water passage hole, which is constructed as a hole formed on the outer ring structure 3 and connects the inner and outer peripheral walls of the outer ring structure 3. The water passage hole is located between two adjacent blades 2. The water passage hole facilitates the outflow of water from the blade 2. Preferably, the water passage hole is positioned opposite to the water-spraying groove 24 on the blade 2, so that the water in the water-spraying groove 24 can flow out directly through the water passage hole.
[0054] This invention utilizes water-guiding grooves 24 on the blades 2 of the water-guiding structure to guide water flow. Additionally, the water-guiding grooves 24 increase the contact area between the water and the water-guiding surface 21, improving water-guiding efficiency and dispersing the force exerted by the water on the water-guiding surface 21. The through-holes 23 allow some water to flow out, reducing the force on the blades 2 during water-guiding. Furthermore, when the water-guiding structure reverses, the airflow through the through-holes 23 forms a counter-current to clean the water-guiding surface 21.
[0055] The present invention also provides a water-spraying device, including a drive motor and the aforementioned water-spraying structure. The mounting structure on the base 1 of the water-spraying structure is driven and connected to the drive motor. At least one water-spraying structure is provided; for example, one or more water-spraying structures can be provided depending on the required water volume. When the required water volume is small, one water-spraying structure can be provided; when the required water volume is large, two water-spraying structures can be provided. The two water-spraying structures can be driven and connected to the same drive motor, causing the two water-spraying structures to rotate synchronously. It is readily apparent that more than two water-spraying structures can also be provided.
[0056] When water spraying is performed, the drive motor rotates forward, so that the water spraying surface 21 of the water spraying structure is in direct contact with the water. After water spraying is completed, the drive motor rotates in reverse. At this time, the airflow enters through the through hole 23 on the blade 2, flows in from the back water surface 22 of the blade 2, and flows out from the water spraying surface 21. The airflow can clean the dirt adhering to the water spraying surface 21, realizing the self-cleaning function of the blade 2.
[0057] This invention reduces the force exerted by water on the blades 2 of the water-spraying structure by setting water-spraying grooves 24 and through holes 23. It also reduces the force exerted by water on the blades 2 when spraying water. Furthermore, when the water-spraying structure reverses, the airflow through the through holes 23 forms a counterflow to clean the water-spraying surface 21, keeping the blades 2 clean. This reduces the load on the drive motor, reduces the torque carried by the drive motor, and prevents the motor from burning out.
[0058] The present invention also provides a portable air conditioner, comprising: a housing, a cavity formed inside the housing, a first heat exchanger and a second heat exchanger disposed inside the cavity, the first heat exchanger and the second heat exchanger being disposed opposite to each other.
[0059] A water collection tray is provided below the first heat exchanger and the second heat exchanger to collect the condensate left on the first heat exchanger and the second heat exchanger.
[0060] The water receiving tray is equipped with the aforementioned water-spraying structure or device. The blades 2 of the water-spraying structure disperse the water in the water receiving tray onto the heat exchanger, where the water is vaporized and consumed, thus reducing the amount of water in the water receiving tray.
[0061] By employing the aforementioned water-spraying structure, this invention increases the water spraying volume, preventing excessive water from overflowing from the water receiving tray. Furthermore, the water-spraying groove 24 on the blade 2 guides the water flow, controlling its direction to flow towards the heat exchanger and preventing water from splashing onto other electrical components and causing malfunctions.
[0062] Exemplary embodiments of this disclosure have been specifically shown and described above. It should be understood that this disclosure is not limited to the detailed structures, arrangements, or implementations described herein; rather, this disclosure is intended to cover various modifications and equivalent arrangements contained within the spirit and scope of the appended claims.
