Abstract

PURPOSE:To inform that the hot water injected from a shower head is in a proper temp. state by visual sensation effect by energizing a light source part by a control means on the basis of the detected temp. of a water temp. detector detecting the temp. of supplied water. CONSTITUTION:A light source 10 is provided to a light guide 7 and light is transmitted to a light diffusing lens 9 through a color filter 11. When the light 12 of the light source 10 is applied to a water stream 13 from the light diffusing lens 9, the water stream 13 is illuminated by the light 12 colored by the color filter 11. A comparator 17 compares the divided voltage Ve of a water temp. detector 6 and a resistor 18 with comparing reference voltage VS1 to energize a transistor 18 and the light source 10 is driven by the transistor 18. A comparator 19 compares Ve with the second comparing reference voltage VS2 to energize a transistor 20 which in turn controls the base signal of the transistor 18. By setting temp. allowing the light source 10 to light to the use temp. region of a shower, in a state reaching the use temp. region, the shower water stream is illuminated.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a hot water supply shower device.

2. Description of the Related Art Traditionally, this type of shower equipment installed in bathrooms etc. has a configuration in which a suitable temperature is ejected from a shower head via a mixing faucet that mixes hot water and cold water, and others have a configuration in which a suitable temperature is ejected from a shower head via a mixing faucet that mixes hot water with water, and others have a configuration in which hot water is discharged at an appropriate temperature from an instantaneous hot water heater.
Generally, the shower head sprays a suitable temperature at a certain temperature.For example, as shown in Japanese Patent Application Laid-open No. 18458/1983, the temperature of water sprayed from the shower head is displayed numerically on the shower head body. It is designed to display the appropriate temperature status.

Problems to be Solved by the Invention However, with this configuration, there is a disadvantage in that the shower head must be held and the display section must be visually checked.

In other words, although it is possible to accurately determine the temperature of the hot water that is ejected from the shower head, it is difficult to identify the hot water in the bathroom due to the steam that accumulates in the shower. However, it took time and effort to hold the shower head body in hand and visually check the temperature display.

Therefore, the present invention provides a visual effect to notify that the temperature of the hot water spouted from the shower head has reached an appropriate temperature range (from a temperature that does not cause burns to a temperature range that does not feel cold, for example, 39 to 42 degrees Celsius). 1 purpose.

The second purpose is to notify the shower hot water temperature in multiple stages using visual effects.

Means for Solving the Problems In order to achieve the above-mentioned first object, the present invention provides a light source section provided facing the shower head, a water temperature detector for detecting the temperature of the water supplied to the shower head, and a water temperature sensor. The control means is configured to energize the light source section based on the temperature detected by the detector.

In addition, in order to achieve the second object, the present invention provides a light source section provided facing the shower head. It is composed of emitted light colors of jIfi.

Function: With the above-described configuration, the shower device of the present invention emits illumination when the hot water jetted from the shower head is in an appropriate temperature range. As a result, the appropriate temperature state can be confirmed by visually observing the shower jet flow.

Furthermore, the light source section configured with a plurality of luminescent colors and provided facing the jet stream of the shower head can notify the shower jet temperature in stages.

As a result, since the shower jet temperature is reported in the ranges of cold temperature, suitable temperature, and high 1 (burn temperature), the progress of the shower jet temperature can be known just by looking at the jet flow, such as at the beginning of shower use.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In Figures 1 and 2, l is the shower head body, 2
is a hot water supply port that supplies hot water to the shower head main body l, and hot water 3 is sent from the heat source device. 4 is a nozzle plate for spouting the hot water 3, 5 is a sealing material that fixes the nozzle plate 4 to the main body 1, 6 is a water temperature detector that detects the temperature of the hot water 3 fed from the hot water supply port 2, 7 A light diffusing lens 9 is attached to the nozzle plate 4 side with a light guide tube isolated from the hot water chamber 8 of the main body 1. The light pipe 7
A light source 10 is provided and transmits light to a light diffusing lens 9 via a color filter 11. A light beam 12 from the light source 10 is irradiated from the light diffusing lens 9 onto a water stream 13 ejected from a nozzle plate 4 attached to the shower head body 1. water ff1
13 will be illuminated with a colored light beam 12 by a color filter 11. Reference numeral 14 denotes a light source section composed of a light pipe 7, a light diffusing lens 9, a light source IO, and a color filter 11. 15
2 is a control means which energizes the light source 10 of the light source section 14 according to the temperature detected by the water temperature detector 6. FIG. 2(A) shows its control 8 circuit, and FIG. show.

In FIG. 2(A), 16 is a control power supply, 17 is a comparator, which compares the divided voltage Ve of the water temperature detector 6 (thermistor) and the resistor 18 with the comparison reference voltage Vll, and
energize. Transistor 18 drives light source 10 .

A comparator 19 compares the Ve and a second comparison reference voltage Vat to energize the transistor 20, and the transistor 20 is configured to control the base signal of the transistor 18.

The operation of the above configuration will be explained with reference to FIG. 2(B).

The horizontal axis shows the supply water temperature, and the vertical axis shows the voltage and comparator.
The temperature detection voltage ■e, which indicates the operation mode of the light source 10 and the temperature detection voltage 9, tends to rise as the temperature of the water supplied to the hot water chamber 8 increases.For example, at T1 temperature, the input voltage of the comparator 17 V□≦Ve
When this is established, the output becomes "H" and the light source IO is turned on.

Next, when the input voltage of the comparator 19 satisfies V and ≧Ve, the output becomes rH and the transistor 20 is turned on. At this time, the base of the transistor 18 that drives the light source 10 is grounded, so it is turned off and the light source 10 is turned off.

・In other words, the light source 10 in the temperature range from T to T2
will be lit.

As a result, by setting the temperatures T1 to Tt in the shower operating temperature range (for example, 38 to 42°C), the shower water stream will illuminate the situation in which the operating temperature range has been reached.

The embodiment shown in FIG. 3 is a configuration diagram in which a plurality of lights 510 of the light source unit 14 are provided, and the light sources are 10a and a fob.

Next, when the input terminal of the comparator 26 becomes Ve≧VSZ and tl'', the transistor 27 turns on and turns off the light 5tob, and the output of the inverter 28 becomes rH, turning on the light source 10c. As a result, the light source 10a is turned on until the water supply temperature T1, the light source 10b is turned on when it exceeds T1, and the light source 10c is turned on when it exceeds Tt.For example, T, -38°C, T2-42' C, by setting the color filter 11 so that the color is green up to 38°C, orange from 38 to 42°C, and red above 42°C, the color will shine orange in the shower temperature range, and the high temperature Shower jets can be illuminated for each temperature range, red in dangerous areas and green in low-temperature areas.
