Abstract

PURPOSE:To obtain a shower equipment which is electrically safe and which is convenient for use, by electrically separating a mixing valve unit from a setter by using optical signals transmitted via an optical fiber in order to connect the setter with a controller, and by passing the optical fiber through a shower hose. CONSTITUTION:A controller 21 is equipped with an emitter 27 and a receptor 28. It transmits optical signals to a setter 25 from the emitter 27 through an optical fiber 26. The setter 25 converts the optical signals into mechanically received signals and the receptor 28 of a controller 21 receives the converted optical signals. The controller 21 confirms the condition and the quantity of water set by the setter 25, comparing those data with signals from a thermistor 20, controlling a mixing valve driver 19, based on the deviation value. In such a manner a user can use mixed water of desired temperature at the time of taking a shower. The title shower equipment can be safely used in a damp bath room because the setter 25 is electrically isolated, since the mixing valve unit 22 and the setter 25 in a shower head 24 are connected by the optical fiber 26. The structure of this device is safely assured as the optical fiber will not come out of a shower head 24.

Description

DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICATION The present invention relates to a pumped water mixing shower device that mixes hot water and water to obtain an appropriate temperature.

BACKGROUND OF THE INVENTION A conventional shower device of this type, as shown in FIG.
A hot water flow path 1, a water flow path 2, and a hot water side valve body 3, a hot water side valve seat 4, a water side valve body 5, and a water side valve seat 6 are provided in the two flow paths 1.2, respectively, and the two valves are connected to each other. The body 3.5 is fixed to the same shaft 6, and is opened and closed in an inversely proportional manner by a drive device 8 consisting of a motor and gears.

Based on the amount of deviation between the temperature detected by the thermistor 9 that detects the mixed water temperature and the temperature set by the setting device 10, the controller 11
The motor 7 is controlled to obtain mixed water having a temperature equal to the set temperature from the shower head.

(For example, Japanese Utility Model Application Publication No. 55-59223) 8M points to be solved by the invention However, in the above configuration, when installing in a bathroom, if both the hot water mixing device and the setting device are installed outside the bathroom, Users who are using the shower cannot set the temperature, and if only the setting device is installed inside the bathroom, the signal line will be brought inside, and some voltage will be applied to the setting device itself. Dangers such as electrical leakage are likely to occur in a humid bathroom.

The present invention solves these conventional problems and aims to provide a shower device that is electrically safe and easy to use.

Means for Solving the Problems In order to solve the above problems, the shower device of the present invention includes a mixing valve for adjusting the mixing ratio of hot water and water, which is provided outside the bathroom, and a mixing valve that is electrically connected to the mixing valve. A mixing valve unit comprising a mixing valve driving device to drive, a controller controlling the mixing valve driving device, a shower hose provided downstream of the mixing valve unit, a shower head, and a shower head built in the shower head. , a setting device for setting state quantities such as desired temperature and flow rate of mixed water, and an optical fiber disposed within the shower hose and communicating between the setting device and a controller in the mixing valve unit.

According to the above configuration, the present invention sets a desired state quantity by manual operation of the shower head, and the controller controls the mixing valve driving device to obtain mixed water equal to the set state quantity. Communication with the controller uses optical fiber signals, and by passing the optical fiber through the shower hose, the mixing valve unit and setting device are electrically separated.

EXAMPLE An example of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, a hot water valve 13 provided in the local flow path 12,
A mixing valve 16 consisting of a water valve 15 provided in the water side flow path 14, a hot water valve driving device 17 and a water valve driving device 18 that electrically drive the hot water valve 13 and water valve 15 of the mixing valve, respectively. A mixing valve drive device! , the thermistor 20 provided downstream of the mixing valve 16, and the mixing valve driving device L! A mixing valve unit 22 consisting of a controller 21 that controls be done.

The shower head 24 has a built-in setting device 25 for setting a desired mixed water state quantity, and the setting device 25 and the controller 21 in the mixing valve unit 22 are connected through an optical fiber 26, and the optical fiber 26 is connected to the shower head. From the inside of 24, through the shower hose 23 pipe, the mixing valve unit 22
It communicates with the controller 21 within.

The controller has a light emitter 27 and a light receiver 28, and the light emitter 27 sends an optical signal to the setting device 25 through an optical fiber 26, and the setting device 25 mechanically modulates the optical signal and transmits it to the controller. The light receiver 28 of 21 receives the modulated optical signal, and the controller 21 checks the state quantity set by the setting device 25, compares it with the signal of the thermistor 20, and controls the mixing valve drive device 19 according to the deviation amount. You can control the amount of mixed water you want in your shower.

In the above configuration, the mixing valve unit 22 and the setting device 25 in the shower head 24 are configured to communicate through the optical fiber 26, so the setting device 25 is electrically insulated, so it can be safely used even in a humid bathroom. It can be used, the signal line does not peek out from the shower head 24, and it is structurally safe. In addition, the mixing valve 16
The hot water valve 13 and the water valve 15 each have independent drive devices, and have multiple electrical noise sources, but because they are connected to the setting device 25 at a remote location via optical fiber,
Safe against noise.

Fig. 2 shows the state of the optical fiber inside the shower hose, and Fig. d shows the optical fiber simply passed through a general shower hose, making the installation work extremely simple. The photo shows a shower hose with optical fibers embedded inside the hose, which prevents the optical fibers from being affected by hot water and improves durability.

Effects of the Invention As described above, the shower device of the present invention provides the following effects.

(1) The mixing valve unit and setting device are connected via optical fiber, and the setting device is electrically insulated, so it can be used safely and can be controlled independently of electrical noise.

(2) Since optical fiber is used as the signal line, even if a part of the shower hose cracks, the signal will not be interrupted and installation work will be easier.

(3) Since the state quantity can be controlled by manual operation of the shower head, even if hot water unexpectedly comes out, it can be stopped instantly or the temperature can be changed, making it safe and easy to use.
