The present invention relates to a showerhead having a multi-color light emitting display function according to the change in water temperature, and in particular, by improving the core structure of the rotor to generate a strong induced electromotive force compared to the past, various monochromatic colors with different wavelength lengths In addition, by being able to continuously and sufficiently irradiate mixed color light, the water temperature can be visually recognized along with the aesthetic sense, thereby preventing the risk of burns that may occur inadvertently. The present invention relates to a showerhead which is capable of bringing a strong light wavelength into direct contact with the skin and thus exerts therapeutic and bactericidal effects such as acne, hair loss, skin wrinkles and skin damage.

As the standard of living improves, there is a well-being boom that considers the health of users in various household goods. In recent years, new technology products with various functionalities have been introduced in shower heads, which are one of bath equipments that are frequently used in homes. For example, a light emitting device is installed in a casing, so that a specific color is changed according to a change in water temperature. The shower head has been proposed to visually recognize the water temperature by irradiating the light.

In the prior art related to the shower head having a light emitting display function, induction electromotive force (electric) generated between the rotor and the stator in the process of rotating the rotor using the water pressure of the water supplied through the discharge flow path, such as a tubular body. By applying the principle of lighting the light emitting diode on the circuit board by the present invention, there is a 'rotational display type water-temperature sensitive water light emitting device' of the Korean Utility Model Registration No. 20-0373045 proposed by the inventor of the present invention.

According to the prior art configuration, a casing having a discharge flow path and a space portion, a stator disposed on the inner circumference thereof, and water pressure supplied to the inside of the casing are rotated to generate induced electromotive force from the stator to generate multicolored light. Consists of the impeller, the rotor and the light-emitting device integrated to the rotating drive unit to emit to the outside, one or more light emitting diodes rotate with the rotor to generate a variety of mixed color light according to the water temperature changes By allowing the user to visually check the water temperature, the aesthetics can be saved as well as the ability to prepare for sudden changes in water temperature.

In the structure of a conventional shower head having a multi-color light emitting display function, a permanent magnet is used as a stator, and an electromagnet wound with a coil in a bobbin is used as a rotor. Is as shown in FIGS. 9A and 9B.

The rotor (electromagnet) is composed of a pair of cores 145 surrounding the outer circumference of the bobbin 143 wound around the coil 144 in the form of a case and a cover, and the circumferential circumference of the core 145 According to the structure in which the stator (permanent magnet 131) is arranged with a predetermined gap spaced apart, the water pressure acts on the impeller integrally coupled with the rotor, the induction is formed from the stator when the rotor is rotated Electricity can be generated by electromotive force, and the light emitting diode on the circuit board emits light by the structure of the self-powered device.

However, the structure of the rotor according to the prior art is very insufficient to supply sufficient power to light up the light emitting diode, and thus has a problem in that it is difficult to substantially exhibit the light emitting display function as described above.

That is, the magnitude of the induced electromotive force e [V] generated in the coil by the alternating magnetic flux generated inside the core in one magnetic field circuit can be defined by Faraday's Law, which is the magnetic flux chain professor NΦ. It is proportional to the rate of change of [Wb] over time t [s] (e = -Δ (NΦ) / Δt). In other words, the induced electromotive force (e) is proportional to the speed at which the lines of magnetic force passing through the coil change. At this time, when a gap is generated between the core and the core, leakage magnetic flux is generated, and thus the inductance (L) value of the coil is reduced, and thus the magnitude of the induced electromotive force is inevitably reduced.

Considering the functional relationship of the induced electromotive force, the conventional core 145 is a combination of a pair of cases and the cover abuts to form a structure in which a gap between the core and the core must be formed by this structure The leakage magnetic flux is generated through the gap formed between both polarities, and due to the occurrence of the leakage magnetic flux, the induced electromotive force is not maximized.

The present invention has been made to solve various problems as described above, the object of which is to improve the core structure of the rotor to generate a strong induced electromotive force compared to the past, various wavelength lengths vary by temperature range By being able to continuously and sufficiently irradiate monochromatic or mixed colors of light, the temperature of the sprayed water can be visually recognized along with the aesthetic sense, thereby preventing the possibility of burns that may occur due to carelessness. It provides a shower head with multi-color light emitting display function according to the change of water temperature, which can be used for direct treatment of acne, hair loss, wrinkles, and skin damage, as it can directly contact the skin with strong multi-color light wavelengths when bathing. Is in.

In the shower head according to the present invention, as shown in FIGS. 1 and 2, the nozzle cap 20 is coupled to the casing main body 10 including the handle 11 and the head part 12, and the shower head casing H. In the shower head structure of the present invention, the rotating shaft 13 is formed at the center of the nozzle cap 20 where water is sprayed, that is, at the center of the inner space of the head portion 12 of the casing body 10. The stator 30 is fixed on the inner circumferential surface of the head part 12, and the rotation driving part G is seated on the rotation shaft 13 so that the head part 12 is fastened by the fastener 14. The structure is combined to be rotatable within.

Although not shown in the drawings, it may be interposed with a washer to stabilize the fastening state of the fastener 14, in order to maintain the waterproofness of the rotary drive unit (G) around the head of the fastener (14) The rubber cap may be covered.

In the shower head according to the present invention, a discharge passage 15 capable of introducing and receiving water supplied at a predetermined water pressure, and an expanded cylindrical space portion are formed therein, and a nozzle cap 20 for injecting water is provided. The shower head casing H coupled to the open tip side of the space portion, the stator 30 disposed along the inner circumferential surface of the shower head casing H, and the water pressure of the water supplied through the discharge passage 15 Rotating drive unit integrating the impeller 50, the rotor 40, and the light emitting device unit to generate an induced electromotive force from the stator 30 and to receive electricity from the stator 30 so as to emit light of a plurality of colors to the outside. In a typical configuration including G), the rotor 40 includes the bobbin 43 in which the coil 44 is wound, and the stator by minimizing leakage flux by maximizing an overlapping area between both polarities. 30 and rotor In order to maximize the induction electromotive force between the 40, the bobbin 43 is sealed and accommodated without a gap, and consists of a pair of interfitting cores 45 or 46 that are combined in an overlapping form, the light emitting device The unit is a plurality of light emitting diodes 61 which can implement different colors on the circuit board 62 capable of detecting temperature and programming control operation according to the detected temperature by using the current supplied from the rotor 40 as a power source. ) Is mounted to form a characteristic structure capable of selectively continuously irradiating light of a single color or mixed color generating a specific wavelength according to the change in the water temperature of the water supplied through the discharge passage (15).

The handle 11 forms a hollow tubular cylindrical body to form a discharge passage 15 through which water can be introduced, and the discharge passage 15 adjacent to an inner space of the head part 12. As shown in FIG. 4, the front end portion is bent in a direction substantially perpendicular to the rotary blade 51 of the impeller 50 formed on the rear surface thereof so as to smoothly rotate the rotary driving part G. Reference numeral 42 in the figure is a boss coupled to the rotation shaft (13).

The nozzle cap 20 may form a single layer structure in which a plurality of injection holes 21 having a uniform size are formed as shown in FIG. 1, but as shown in FIGS. It is more preferable to form a structure of a pair of inner and outer nozzle caps 22 and 23 superimposed inward and outward so that the size of the thread hole 21 can be adjusted by a rotational operation of a predetermined angle with respect to either side. Do.

The stator 30 may be composed of a permanent magnet piece 31 in the form of a ring or an intermittent ring arranged with a predetermined gap as in the embodiment of FIGS. 2 and 3B, or of FIG. 5B. As in the embodiment, the N pole and the S pole may be configured as a permanent magnet plate 32 in the form of discs arranged consecutively adjacent to each other, which is the stator 30 according to the position of the impeller 50 This is due to a design problem with a point that may be adjacent to the cores 45 and 46 of the rotor 40. That is, when the impeller 50 is formed on the rear side of the rotor 40, the stator 30 is in the form of an intermittent ring, and when the stator 30 is formed on the circumference of the rotor 40, the stator 30 is formed. Each can be configured in the form of a disc.

In the embodiment of the present invention, the stator 30 is a permanent magnet and the rotor 40 is an electromagnet only. However, in some cases, the rotor 40 is a permanent magnet. The stator 30 may be configured as an electromagnet.

In the rotation driving unit G, the rotor 40, the impeller 50, and the light emitting device unit (the display unit 60) form a single body by one housing 41.

As described above, the rotor 40 includes a bobbin 43 in which the coil 44 is wound, and a core 45 or 46 surrounding the bobbin 43. At this time, as shown in one embodiment shown in Figures 3a and 3b and other embodiments shown in Figures 5a and 5b, respectively, the pair of cores 45 or 46, the outer peripheral surface of the bobbin 43 The sawtooth can be fitted and wrapped and formed to be hermetically sealed, and the inner circumferential surface of the bobbin 43 can be overlapped and enclosed and sealed. In view of the permeability, a material of the cores 45 and 46 is most ideal to use a silicon steel sheet. In the drawings, 45a and 45b and 46a and 46b are respectively applied to the cores 45 and 46. Each of the pair of core overlaps formed is shown.

In the above embodiment, the core 45 of FIG. 3A has a structure in which two members are coupled, and the core 46 of FIG. 5A has a structure in which three members are coupled.

In the configuration of the cores 45 and 46, the inner circumferential portion of the core 45 or 46 is concentric with both flange portions (meaning the portions of the core overlapping portions 45a and 45b or 46a and 46b). To form a tightly overlapping hermetic coupling structure without mutual gaps, and the outer circumferential portion that is fitted in the form of a sawtooth is a hermetic coupling structure in which the coupling gap a of the core (see the partially enlarged view of FIGS. 3A and 5A) is maintained within 1 mm. By this, it is possible to maximize the induction of the electromotive force (change of magnetic force) between the stator 30 and the rotor 40.

According to this structure, the sealing properties of the coil 44 and the bobbin 43 are remarkably improved, thereby minimizing leakage flux and eddy current loss of the coil 44, and maximizing the inductance (L) as a result. The electromotive force can be generated, and thus, it is possible to secure a continuous and sufficient current capable of emitting the light emitting diodes 61.

As shown in Fig. 6, the light emitting device portion (display portion 60) is activated by using the electric power generated from the rotary drive portion G, and the stator in the temperature detection portion D on the circuit board 62. After detecting the water temperature using the water filled in the gap between the 30 and the rotor 40, the light emitting diode 61 matching the temperature detection value by the program set in the control circuit part C on the circuit board 62 is detected. ) And the light is irradiated with a predetermined color. Although not shown in detail, the control circuit unit C on the circuit board 62 generates a frequency that changes according to a change in resistance component or capacitance of water between the stator 30 and the rotor 40. An oscillation circuit, a tuning circuit (smoothing circuit) for tuning the change of this frequency, a rectifying circuit (detection circuit) for converting the tuned frequency into a DC component, an amplifying circuit (constant voltage circuit) for amplifying the rectified signal, and the like. It can be configured to include. In particular, the constant voltage circuit controls the change in the brightness of the light emitting diode 61 due to the external voltage fluctuation due to the pressure difference due to the local environmental factors to maintain a constant brightness at all times.

For reference, the water temperature detection and light emission principle according to the structure of the present invention will be described. When a certain water temperature is transmitted to a temperature sensor (not shown) in which water starts to fill in the shower head casing H, the temperature sensor and the circuit board 62 are transferred. The voltage is divided by a reference resistor connected in series to the phase. At this time, when the water temperature rises, the resistance value of the temperature sensor decreases, so that the voltage of the input terminal side of the control circuit unit C reading the voltage also decreases. On the contrary, when the water temperature decreases, the resistance value of the temperature sensor increases. The voltage at the input terminal side of the control circuit section C reading the voltage also becomes high. In the control circuit unit (C), the change in the partial pressure by the temperature sensor and the reference resistance value is compared with a preset input value, thereby emitting light of a color corresponding to the corresponding water temperature. However, the magnitude of the induced electromotive force may also vary because the rotational speed of the rotary drive unit G may vary depending on the degree of water pressure, which affects the reference resistance value and the voltage applied to the temperature sensor. In order to solve this problem, the constant voltage circuit may be used to output a constant voltage even if the input voltage is severely changed.

In addition, the light emitting diode 61 includes red (R), green (G), and blue (B) light emitting diodes, and the differential time is determined according to the change in water temperature at which the light emitting diodes 61 of each color are sensed. As it is blinking during the change from low temperature water to high temperature water, it is possible to irradiate light of blue, blue green, yellow, purple, colorless and red, which are light wavelengths that can exhibit different colors and human efficacy.

Table 1 below shows an example of the color combination of the light emitting diode 61 according to the change in water temperature and the human efficacy according to each color wavelength.

[Table 1] Example of light emission color combinations of light emitting diodes

However, the color combination of the light emitting diode can be changed in various ways according to the input program. Therefore, when the supply water is high temperature, the high temperature (red) light emitting diode is selectively controlled at low temperature, the low temperature (blue or green) light emitting diode at low temperature, and all the light emitting diodes at the temperature range are selectively flashed for a suitable time. In addition, it is possible to implement a variety of monochrome or mixed colors by rotational drive.

According to the shower head according to the present invention as described above, it is possible to generate a strong induced electromotive force compared to the conventional by applying a superimposed core, so that the continuous light of various monochromatic or mixed color light having a different wavelength length for each water temperature zone By being able to investigate sufficiently, it is possible to visually recognize the temperature of the sprayed water with a sense of aesthetics, and to prevent the possibility of burns that may occur inadvertently. It can be directly in contact with the skin, and can exhibit various human effects such as acne, hair loss, skin wrinkles and skin damage, as well as sterilizing bacteria in the skin.

Although the present invention has been described with reference to the embodiments shown in the accompanying drawings, this may be regarded as exemplary, and a person of ordinary skill in the art may conceive various modifications and equivalent embodiments therefrom. It should be understood that such equivalent embodiments are also included within the claims of the present invention.
