Abstract

The application provides a water distribution structure and a fan with uniform water distribution. The water distribution structure comprises a shell and a water distribution column. The water distribution column is provided with water flow channels penetrating through the shell. The side wall of the water distribution column is provided with water outlets. The water flow channels communicate with the containing cavity through the water outlets. The flow area of the water outlets gradually increases in the direction away from the bottom surface of the containing cavity. The water distribution structure and the fan with uniform water distribution provided by the application gradually increase the flow area of the water outlets with the increase of the height of the water distribution column, which can ensure uniform water distribution of all water flow channels. When the flow is large, the water flow can simultaneously flow through the side openings and the top opening. When the water in the water tank decreases, the amount of water pumped by the water pump into the water distribution structure also decreases. The water flow enters through the side openings. The smaller the flow, the smaller the aperture of the water outlet. Ultimately, uniform water distribution is ensured, and the cooling effect of the fan is ensured.

Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to a water distribution structure and fan that distributes water evenly. Background Technology

[0002] The cooling fan pumps water from the bottom tank to the top water distribution structure, where it is then cooled by an evaporative cooling mechanism. Unevaporated water is returned to the tank via a collection structure. However, current technology typically uses openings or countersunk holes at the bottom of the water distribution structure. Since the water level in the tank varies and the pump flow rate is not constant, some of the distribution holes may fail when the flow rate is low, leading to uneven water distribution and affecting the cooling effect of the evaporative cooling components. Summary of the Invention

[0003] To address the technical problem of uneven water distribution in existing water distribution structures affecting cooling performance, a water distribution structure and fan with uniform water distribution, wherein the flow area of ​​the water inlet gradually increases with height, are provided.

[0004] A water separation structure, comprising:

[0005] A housing having a receiving cavity formed within it;

[0006] A water distribution column is disposed on the bottom surface of the receiving cavity, and a water flow channel penetrating the shell is provided on the water distribution column, and a water outlet is provided on the side wall of the water distribution column, and the water flow channel is connected to the receiving cavity through the water outlet.

[0007] The water distribution column has a first end and a second end, the first end is disposed on the bottom surface of the receiving cavity, and the water flow channel passes through the second end of the water distribution column to form an inlet.

[0008] The flow area of ​​the water outlet gradually increases along the direction away from the bottom surface of the receiving cavity.

[0009] The water inlet is elongated and its width gradually increases along the direction away from the bottom surface of the receiving cavity.

[0010] The water inlet is trapezoidal in shape, with the lower base of the trapezoid smaller than the upper base, and the lower base of the trapezoid being on the same plane as the bottom surface of the receiving cavity; or the lower base of the trapezoid being lower than the bottom surface of the receiving cavity.

[0011] The water inlet is elongated and divided into at least two water passage sections, and the width of all water passage sections gradually increases along the direction away from the bottom surface of the receiving cavity.

[0012] The number of water-distributing columns is multiple, and all the water-distributing columns are evenly distributed on the bottom surface of the receiving cavity.

[0013] The water distribution column has a rectangular cross-section, and the water outlet is located on the first side of the rectangle.

[0014] The water distribution column has a second side opposite to the first side, and at least one of the water distribution columns is also provided with the water outlet on the second side, and the flow area of ​​the water outlet on the second side is smaller than the flow area of ​​the water outlet on the first side.

[0015] A fan comprising the aforementioned water distribution structure.

[0016] The water distribution structure and fan provided by this invention, which provides uniform water distribution, gradually increase the flow area of ​​the water inlet as the height of the water distribution column increases, ensuring uniform water distribution in all water channels. When the flow rate is high, water can flow simultaneously through both the side and top openings. When the water in the tank decreases, the amount of water pumped into the water distribution structure also decreases, and water flows in through the side openings. The lower the flow rate, the smaller the diameter of the water inlet, ultimately ensuring uniform water distribution and thus guaranteeing the cooling effect of the fan. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.

[0023] like Figures 1 to 3The water distribution structure shown includes a housing 1, within which a receiving cavity is formed, into which a water pump can pump water; a water distribution column 2, disposed on the bottom surface of the receiving cavity, and having a water flow channel 21 penetrating the housing 1; and a water outlet 22 on the side wall of the water distribution column 2. The water flow channel 21 communicates with the receiving cavity through the water outlet 22, allowing water pumped into the receiving cavity to enter the water flow channel 21 through the water outlet 22, and then flow out of the housing 1 through the water flow channel 21 and be distributed to the required structures; because the flow rate of the water pump in the prior art is not constant... The water level in the cavity is unstable, and when the water flow is low, some of the water distribution holes will fail, resulting in uneven water distribution and affecting the cooling effect of the water evaporation component. Therefore, in this application, the flow area of ​​the water outlet 22 gradually increases along the direction away from the bottom surface of the cavity, so that each water outlet 22 can distribute water evenly according to the water level in the cavity, thereby ensuring the cooling effect of the fan. Preferably, the lowest point of the water outlet 22 is on the same horizontal plane as the bottom surface of the cavity or the lowest point of the water outlet 22 is lower than the bottom surface of the cavity.

[0024] The water distribution column 2 has a first end and a second end. The first end is located on the bottom surface of the receiving cavity, and the water flow channel 21 passes through the second end of the water distribution column 2 to form an inlet. When the water level in the receiving cavity is higher than the height of the water distribution column 2, water can also enter the water flow channel 21 from the inlet.

[0025] The water outlet 22 is elongated and its width gradually increases along the direction away from the bottom surface of the receiving cavity. That is, as the water level in the receiving cavity increases, the flow rate into the water flow channel 21 increases, ultimately ensuring uniform water distribution of the water distribution structure.

[0026] The water inlet 22 is trapezoidal in shape, with the lower base of the trapezoid being smaller than the upper base, and the lower base of the trapezoid being on the same plane (same horizontal plane) as the bottom surface of the receiving cavity; or the lower base of the trapezoid being lower than the bottom surface of the receiving cavity.

[0027] The water inlet 22 is elongated and divided into at least two water passage sections. Along the direction away from the bottom surface of the receiving cavity, the width of all the water passage sections gradually increases, that is, the water inlet 22 is stepped.

[0028] The number of water-distributing columns 2 is multiple, and all the water-distributing columns 2 are evenly distributed on the bottom surface of the receiving cavity.

[0029] The cross-section of the water-dividing column 2 is rectangular, and the water outlet 22 is disposed on the first side of the rectangle.

[0030] The water distribution column 2 has a second side opposite to the first side, and at least one of the water distribution columns 2 is also provided with the water outlet 22 on the second side. The flow area of ​​the water outlet 22 on the second side is smaller than the flow area of ​​the water outlet 22 on the first side. The water outlet 22 on the second side is used to discharge the residual water in the water distribution structure, while avoiding the water outlet 22 on the second side from causing changes in the water distribution uniformity of the water distribution column.

[0031] A fan comprising the aforementioned water distribution structure.

[0032] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
