Description

Technical Field

[0001] The invention relates to the technical field of household appliances, and in particular to a water distribution structure and a cooling fan. Background Art

[0002] The existing water distribution method of cooling fans mainly relies on the water distribution groove on the top of the wet curtain assembly to distribute water. The water distribution groove is evenly provided with water distribution holes. The water in the water tank enters the water distribution groove through the water channel designed inside the fuselage, and then flows to the wet curtain through the evenly distributed water distribution holes.

[0003] Generally, a water tank is arranged below the cooling fan, and a water distribution tank is arranged above the cooling fan. The water in the water tank is pumped to the water distribution tank through a bellows under the pump pressure of a water pump. A water inlet hole is opened on the water distribution tank, and the bellows is connected to the water inlet hole.

[0004] However, there is only one water inlet. Under the action of the pump pressure, the water flow rate out of the water inlet is high, and then the flow rate gradually decreases, which will cause the water distribution holes near the water inlet to have a larger water output than the water distribution holes far away from the water inlet due to the high water flow rate, thereby causing the problem of uneven water distribution through the water distribution holes. The uneven water distribution through the water distribution holes means that the amount of water acting on different positions of the wet curtain is different, thereby affecting the cooling effect of the cold fan. Summary of the invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect of uneven water distribution in the water distribution structure of the cooling fan in the prior art, thereby providing a water distribution structure and a cooling fan.

[0006] In order to solve the above problems, the present invention provides a water diversion structure, including a water trough, a water inlet hole and a plurality of water diversion holes arranged at the bottom of the water trough, and also includes a water inlet buffer trough, which is arranged under the bottom of the water trough and connected to the water trough, and the water inlet hole is arranged in the water inlet buffer trough.

[0007] Furthermore, the water inlet hole is arranged at the bottom of the water inlet buffer tank.

[0008] Furthermore, the water inlet buffer tank is arranged away from the water diversion hole.

[0009] Furthermore, an opening is provided on the bottom of the water tank, and the notch of the water inlet buffer tank is butted against the opening.

[0010] Furthermore, the water inlet buffer groove is formed by a partial depression of the bottom of the water tank.

[0011] The water diversion structure in the present invention also includes a water inlet structure arranged at the water inlet hole, and the water inlet structure includes: a water inlet pipe interface, which is arranged below the bottom of the water inlet buffer tank and is connected to the water inlet; a splash guard, which is connected to the water inlet and placed inside the water inlet buffer tank, and is provided with a water outlet, and the water outlet is arranged toward the tank wall of the water inlet buffer tank.

[0012] The water diversion structure in the present invention also includes a water retaining rib protruding from the bottom of the water tank, the water tank is divided into a water storage tank and a water diversion tank by the water retaining rib, the water diversion hole is arranged in the water diversion tank, and the water inlet buffer tank is arranged on the water storage tank.

[0013] The water diversion structure in the present invention further comprises an overflow hole, which is arranged at the bottom of the water tank and the upper edge of the overflow hole is higher than the water retaining rib.

[0014] Furthermore, the overflow hole is arranged close to the water inlet buffer tank.

[0015] The present invention also provides a cooling fan including any of the above-mentioned water separation structures.

[0016] The technical solution of the present invention has the following advantages:

[0017] 1. The water diversion structure of the present invention includes a water tank, a water inlet hole and a plurality of water diversion holes arranged at the bottom of the water tank, and also includes a water inlet buffer tank, which is arranged below the bottom of the water tank and connected to the water tank, and the water inlet hole is arranged in the water inlet buffer tank.

[0018] In the present invention, the water inlet buffer tank is arranged below the bottom of the water tank, and the water inlet hole is arranged in the water inlet buffer tank. The external water first enters the water inlet buffer tank through the water inlet hole, and after gradually filling the water inlet buffer tank, it will gradually overflow from the water inlet buffer tank into the water tank. Before the water inlet buffer tank is filled, the water inlet hole will be gradually submerged by water. The water coming out of the submerged water inlet hole will be hindered by the surrounding water and its pump pressure kinetic energy will be reduced, thereby reducing the flow rate of the overflowing water in the water inlet buffer tank, making it closer to natural flow. Furthermore, the water flow velocity difference at different positions away from the water inlet hole is reduced, ensuring that the water flow velocity at each water distribution hole is basically the same, thereby ensuring the uniformity of water distribution.

[0019] 2. The water inlet hole in the water diversion structure of the present invention is set at the bottom of the water inlet buffer tank. The water coming out of the water inlet hole at this position is subject to the greatest water resistance, which is more conducive to reducing the pump pressure kinetic energy of the water coming out of the water inlet hole, making it closer to the natural flow rate.

[0020] 3. In the water diversion structure of the present invention, the water inlet buffer groove is arranged far away from the water diversion hole. The advantage of this design is that the farther the water inlet buffer groove is from the water diversion hole, the more kinetic energy it consumes during the flow process, the smaller the flow velocity difference reaching the water diversion hole, and the more conducive to the uniformity of water distribution.

[0021] 4. The water-dividing structure in the present invention also includes a water inlet structure arranged at the water inlet hole, and the water inlet structure includes: a water inlet pipe interface, arranged below the bottom of the water inlet buffer tank, and connected to the water inlet; a splash-proof cover, connected to the water inlet, and placed inside the water inlet buffer tank, with a water outlet opened thereon, and the water outlet is arranged toward the wall of the water inlet buffer tank. The water coming out of the water outlet will spray toward the wall of the water inlet buffer tank, and the pump pressure kinetic energy will be reduced by the obstruction of the wall, which can greatly reduce its flow rate.

[0022] 5. The water-dividing structure of the present invention also includes a water retaining rib disposed at the bottom of the protruding water tank. The water tank is divided into a water storage tank and a water-dividing tank by the water retaining rib. The water-dividing hole is disposed in the water storage tank, and the water inlet buffer tank is disposed on the water storage tank. The water retaining rib is disposed so that the water coming out of the water inlet buffer tank is blocked by the water retaining rib in the process of flowing to the water-dividing hole, and gradually fills up the water storage tank. The water whose flow rate is reduced by the water retaining rib naturally flows through the water retaining rib after the water storage tank is filled and flows evenly to the water-dividing hole, which can greatly improve the uniformity of water distribution.

[0023] 6. The water diversion structure of the present invention also includes an overflow hole, which is arranged at the bottom of the water tank and the upper edge of the overflow hole is higher than the water retaining rib. When the water diversion hole is blocked, the water level in the water tank will gradually rise. When the water level rises to a certain height, it can overflow through the overflow hole, preventing it from overflowing from the water tank and overflowing into the machine, affecting the use of the machine. The upper edge of the overflow hole is higher than the water retaining rib to ensure that when the water diversion hole is normally diverting water, the water in the water storage tank will not enter the overflow hole and affect the water diversion effect.

[0024] 7. The overflow hole in the water diversion structure of the present invention is arranged close to the water inlet buffer tank. When overflow is required, the overflow hole is arranged close to the water inlet buffer tank, and the water from the water inlet buffer tank can be directly overflowed to the outside, thereby improving the overflow efficiency.

[0036] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0040] Example 1

[0041] Figures 1 to 3 As shown, a water distribution structure provided for this embodiment includes a water tank 1, a water inlet hole and a plurality of water distribution holes 3 arranged at the bottom of the water tank 1, and also includes: a water inlet buffer tank 4, which is arranged below the bottom of the water tank 1 and connected to the water tank 1, and the water inlet hole is arranged in the water inlet buffer tank 4.

[0042] like Figure 1 In the example given in FIG. 1 , the water tank 1 in this embodiment is a commonly used square water tank, and a plurality of evenly distributed water diversion holes 3 are processed on one side of the water tank 1 .

[0043] through Figure 1 As shown in the figure, it can be clearly seen that in this embodiment, the water inlet buffer groove 4 is arranged below the bottom of the water tank 1, and the water inlet hole is arranged in the water inlet buffer groove 4. The external water first enters the water inlet buffer groove 4 through the water inlet hole, and after gradually filling the water inlet buffer groove 4, it will gradually overflow from the water inlet buffer groove 4 into the water tank 1. Before the water inlet buffer groove 4 is filled, the water inlet hole will be gradually submerged by water. The water coming out of the submerged water inlet hole will be hindered by the surrounding water and its pump pressure kinetic energy will be reduced, thereby reducing the flow rate of the overflowing water in the water inlet buffer groove 4, making it closer to natural flow. Further, the water flow velocity difference at different positions away from the water inlet hole is reduced, ensuring that the water flow velocity at each water distribution hole 3 is basically the same, thereby ensuring the uniformity of water distribution.

[0044] Furthermore, the water inlet hole in this embodiment is processed at the bottom of the water inlet buffer tank 4. The water coming out of the water inlet hole at this position is subject to the greatest water resistance, which is more conducive to reducing the pump pressure kinetic energy of the water coming out of the water inlet hole, making it closer to the natural flow rate.

[0045] Of course, in some other embodiments, the water inlet hole can also be set on the groove wall of the water inlet buffer groove 4, which has the same technical effect.

[0046] Furthermore, when the water inlet hole is arranged at the wall of the water inlet buffer groove 4, it is better to arrange it closer to the bottom of the groove, because the water resistance it receives at the above position is the greatest.

[0047] like Figure 1 As shown in the figure, the water inlet buffer groove 4 is arranged far away from the water diversion hole 3. The farther the water inlet buffer groove 4 is from the water diversion hole 3, the more kinetic energy it consumes during the flow process, and the smaller the flow velocity difference reaching the position of the water diversion hole 3, which is more conducive to the uniformity of water distribution.

[0048] The following describes the arrangement of the water inlet buffer tank 4:

[0049] like Figure 2 As shown in the figure, the water inlet buffer groove 4 is formed by a partial depression in the bottom of the water tank 1. The water inlet buffer groove 4 in this embodiment is integrally formed on the bottom of the water tank 1. The integrated processing can improve the production efficiency and simplify the assembly.

[0050] In some other embodiments, the water inlet buffer groove 4 can be detachably installed on the bottom of the water sink 1. For example, an opening is processed on the bottom of the water sink 1, and the groove of the water inlet buffer groove 4 is docked at the opening. Some connecting structures, such as screw holes, are arranged at the above-mentioned opening and the edge of the groove of the water inlet buffer groove 4, and then the two are fixed together using the screw holes.

[0051] Furthermore, in order to prevent water leakage, sealant can be used at the joint gap between the water tank 1 and the water inlet buffer tank 4. For example, waterproof caulking sealant is a single-component butyl rubber building waterproof sealant. It does not contain aromatic hydrocarbon toxic solvents and is an environmentally friendly product. It has good adhesion to the surface of concrete, metal, wood, stone, plastic steel and polycarbonate.

[0052] In order to further ensure the uniformity of water distribution in this embodiment, a water inlet structure 2 is also provided.

[0053] like Figure 2 and Figure 3 As shown in FIG. 1 , the water inlet structure 2 is formed at the water inlet. Figure 3 The specific structure of the water inlet structure 2 is shown, including: the water inlet pipe interface 21 is formed under the bottom of the water inlet buffer tank 4, connected with the water inlet, and a plurality of annular protrusions are formed on the peripheral surface of the downward end of the water inlet pipe interface 21, and the external water pipe is directly sleeved on the above-mentioned water inlet pipe interface 21 to realize water supply to the water tank 1. At the other end of the water inlet, there is a splash-proof cover 22, which is completely accommodated in the water inlet buffer tank 4, and is in the shape of a tube with one end closed, and a water outlet 23 is opened on the tube wall, and the water outlet 23 is arranged toward the wall of the water inlet buffer tank 4. The water coming out of the water outlet 23 will be sprayed toward the wall of the water inlet buffer tank 4, and the pump pressure kinetic energy is reduced by the obstruction of the wall, which can greatly reduce its flow rate.

[0054] Furthermore, in this embodiment, the bottom of the protruding water tank 1 is formed with a water retaining rib 5, such as Figure 1In the example, the water diversion hole 3 is coaxially and evenly formed on the bottom of the water tank 1, the water retaining rib 5 is basically arranged in parallel with the setting direction of the water diversion hole 3, and the water tank 1 is divided into a water storage tank 11 and a water diversion tank 12 by the water retaining rib 5, the water diversion hole 3 is formed in the water diversion tank 12, and the water inlet buffer tank 4 is formed on the water storage tank 11. The structure of the water retaining rib 5 is a baffle structure connected between two opposite tank walls. Obviously, the upper end of the water retaining rib 5 should be higher than the height of the water diversion hole 3. Therefore, the setting of the water retaining rib 5 makes the water coming out of the water inlet buffer tank 4 blocked by the water retaining rib 5 in the process of flowing to the water diversion hole 3, and gradually fills up the water storage tank 11. The water whose flow rate is reduced by the water retaining rib 5 naturally flows through the water retaining rib 5 after the water storage tank 11 is filled and flows evenly to the water diversion hole 3, which can greatly improve the uniformity of water distribution.

[0055] like Figure 1 It also includes an overflow hole 6, which is formed at the bottom of the water tank 1 and the upper edge of the overflow hole 6 is higher than the water retaining rib 5. When the water diversion hole 3 is blocked, the water level in the water tank will gradually rise. When the water level rises to a certain height, it can overflow through the overflow hole 6 to prevent it from overflowing from the water tank 1 and overflowing into the machine, affecting the use of the machine. The upper edge of the overflow hole 6 is higher than the water retaining rib 5 to ensure that when the water diversion hole 3 is normally diverting water, the water in the water storage tank 11 will not enter the overflow hole 6 and affect the water diversion effect.

[0056] Furthermore, the overflow hole 6 is arranged close to the water inlet buffer groove 4. When overflow is required, the overflow hole 6 is arranged close to the water inlet buffer groove 4, which can directly overflow the water from the water inlet buffer groove 4 to the outside, thereby improving the overflow efficiency.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
