Description

Shower head with built-in generator{A SHOWER HEAD WITH A BUILT-IN GENERATOR}

One embodiment of the present invention relates to a shower head, and more specifically, to a shower head with a built-in generator.

A generator converts mechanical energy such as water power, wind power, tidal power, etc. into electrical energy. In most of these generators, when a rotor with an impeller rotates, electrical energy is output from a power plant element equipped with a coil.

The electrical energy output from the generator is supplied to a charging module for storage or directly supplied to a specific device and used as an energy source for operation.

Among the above-described generators, a generator that generates electricity using the flow force of a fluid such as water has also been developed. However, the conventional generator that generates power using the flow force of the fluid was unable to generate smooth power generation due to the low rotation speed of the rotor. As a result, there was a problem in that it could only produce electrical energy at a low voltage that did not meet expectations.

The smaller the size, the lower the power generation efficiency, and when installed on a pipe through which fluid flows, there is considerable difficulty in installation, and the rotation speed of the rotor is less than expected, resulting in even lower power generation efficiency.

Meanwhile, various technologies have been developed for the purpose of improving the cleaning power of water sprayed through a shower and providing a refreshing feeling.

Korean Registered Utility Model No. 20-0456993 proposes a shower device equipped with a light that emits light when the shower is used, and Korean Patent Application No. 10-2004-0107259 provides a far-infrared lamp that emits far-infrared rays when the shower is used. However, a technology has been proposed in which the far-infrared lamp is driven by electrical energy produced by a generator provided in the shower when the shower is used.

These conventional technologies had to be small in size because the power generating magnets were formed in the shower pipe. Therefore, a power generation device that increases power generation efficiency by increasing its size can be considered.

1 to 6, the shower head 100 with a built-in generator according to an embodiment of the present invention includes a housing 103, an inner case 160, a magnet portion 140, and a rotor 130. Includes.

The housing 103 forms the exterior of the shower head 100 and includes an upper cover 101 and a lower cover 102. The housing 103 may be formed using metal or synthetic resin. An inlet 102a through which fluid flows is formed on one side of the lower cover 102. Power generation occurs as a fluid such as water or seawater moves through the inlet 102a. Additionally, a fluid such as air or water vapor may be used.

The upper cover 101 includes a frame coupled to the lower cover 102 and a plate 104 coupled to the frame. The plate 104 may be shaped like a disk and has micro holes through which running water is discharged. The micro holes include third micro holes near the center of the disk, first micro holes 104a formed on the outside of the third micro holes, and second micro holes formed on the outside of the first micro holes 104a. It may be formed including fields 104b.

The inner case 160 may be coupled to the lower cover 102. The inner case 160 is formed to accommodate the main core 110 and coils 111. The main core 110 is formed so that the coils 111 can be wound, and is formed to extend from the center to the outside. The main core 110 has a total of nine branches, and coils 111 are wound on each branch. One end of the branch portion corresponding to the outside is formed to face the magnet of the magnet portion 140 and is formed to have a constant area.

The magnet portion 140 is formed to face the outer periphery of the inner case 160. For example, the magnet unit 140 may be formed by alternating a total of six pairs of N poles and S poles. The magnet portion 140 is fixed to the rotor 130 that rotates when fluid flows in. The rotor 130 is arranged to surround the outer periphery of the inner case 160. The main shaft 120 is formed to support the rotation of the rotor 130. The main shaft 120 is coupled to the lower cover 102. The main shaft 120 is formed by penetrating the inner case 160, and a bushing 121 is disposed between the inner case 160 and the main shaft 120.

The rotor 130 is provided with wings 131 so that fluid is discharged through microholes when fluid flows in. The wings 131 guide the fluid to be discharged into the fine holes. The wings 131 extend in a spiral direction from the center of the rotor 130 to the outside.

For smoother rotation, the height of the wing portion 131 is gradually lowered from the outer edge to the hollow portion. Here, the height of the wing portion 131 refers to the portion extending from one surface of the rotor 130 toward the plate 104.

The rotor 130 is arranged to fill the internal space of the shower head 100 so that sufficient output can be generated even if the fluid flows at a relatively low speed.

Referring to FIGS. 2, 3, and 5, one surface of the rotor 130 facing the upper cover includes a first surface 133 and a second surface 134. The first surface 133 is a surface including the center, and the second surface 134 is a surface formed on the outside of the first surface 133. The distance d1 between the first surface of the rotor 130 facing the first micro holes 104a and the first micro holes 104a is the distance d1 between the rotor 130 facing the second micro holes 104b. ) is formed shorter than the distance d2 between the second surface 134 and the second micro holes 104b. This is to facilitate smooth rotation of the rotor 130 and discharge of fluid. It is possible to obtain a slightly faster rotation speed of the rotor 130 than when the distance between d1 and d2 is the same.

Additionally, the rotor 130 includes a partition wall 132 extending vertically from the first surface 133. This is to guide the discharge of fluid into the microholes when fluid flows in due to the rotation of the rotor 130. Additionally, the partition wall 132 forms a hollow space between the center of the rotor 130 and the plate 104. A gap is formed between the partition 132 and the plate 104. Some of the fluid flows in through the gap. The introduced fluid may cool the main shaft 120 that supports the rotation of the rotor 130. One surface of the main shaft 120 is exposed to the hollow space so that it can be cooled by fluid.

In this way, the shower head 100 with a built-in generator according to an embodiment of the present invention has a wing portion 131 of the rotor 130 from the partition wall 132 where the main shaft is disposed to the inlet 102a through which fluid flows. extends in a spiral shape, enabling sufficient output even when fluid flows in at low speed. In addition, by using the remaining space excluding the inner case 160 as a space where the rotor 130 rotates according to the inflow of fluid, sufficient efficiency can be achieved even in a relatively small space.

The shower head with a built-in generator described above is not limited to the configuration and method of the above-described embodiments, but all or part of each embodiment can be selectively used so that various modifications can be made. It may also be composed in combination.
