Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shower device, and more particularly, it is possible to set a shower temperature by changing a mixing ratio of hot water and hot water by an electric mixing valve, and to select a shower type of rain or rain. The present invention relates to a shower device which can be selected for a shower in the form of mist or the like, and a shower water.

[0002]

2. Description of the Related Art A so-called multifunctional shower device, which can arbitrarily select a shower type such as rain (squall) or mist (mist), and a boiling water, has already been put into practical use. It is already known that a functional shower device allows the shower temperature to be freely set by operating a switch, and in such a shower device, an arbitrarily selected type of shower can be operated under the set temperature. To be able to squirt.

The control of the shower temperature is generally performed by changing the mixing ratio of hot water from a hot water supply device such as an electric water heater and cold water from a water pipe or the like by introducing it to a shower nozzle by changing the electric mixing valve. The electric mixing valve drives the electric motor by a temperature control signal that changes according to the temperature set by the temperature setting switch, and changes the position of the mixing valve to change the mixing ratio of the fluid from the hot water supply pipe and the water supply pipe. There is.

[0004]

By the way, if the hot water shower and the rainy or foggy shower are discharged at the same temperature, the sensible temperature of the shower bather will be considerably different.

That is, the shower water is discharged in a rod shape from the nozzle and hits the person taking a shower. In a rainy or mist-like shower, the droplet water is discharged from the nozzle and is cooled by the air in the bathroom. Even if the hot water discharged from the nozzle is the same, the temperature will be different at the time of reaching the shower bather. The decrease in temperature after tapping becomes more remarkable as the shower particles are made finer.

In the case of the shower water, the shower hits the body almost locally, but almost entirely on the hot water, but in the rain shower or the mist shower, the shower water and the air are blown. Since these hit the body in a mixed state, this also causes a reduction in the sensible temperature of the rainy or mist-like shower.

The present invention has been made in view of the above point, and in the state where the shower temperature is set to be the same, whether the shower shower is a shower shower or a rain shower or a mist shower is selected, the shower is selected. It is an object of the present invention to provide a shower device that can constantly keep the sensible temperature of a bather.

[0008]

A structure for achieving the above object will be described with reference to the basic conceptual diagram shown in FIG. 1. In the present invention, a hot water supply pipe and a hot water supply pipe are provided by the operation of a valve based on a temperature control signal. An electric mixing valve a that changes the mixing ratio of the fluid from the water supply pipe and guides it to the shower nozzle is provided, and the type of shower ejected from the shower nozzle is at least a rain shower or a mist shower and a shower water shower. In a shower device provided with a shower type selection unit b for selecting any one, a shower type detection unit c for detecting the selected shower type, and a temperature control signal to be supplied to the electric mixing valve a based on the detection result. The temperature control signal changing means d for changing the size of the shower is provided, and when the rainy or foggy shower is selected, the boiling water is selected. Characterized by the magnitude of the temperature control signal so that the shower temperature is relatively high is configured to be determined than if.

[0009]

The magnitude of the temperature control signal to be supplied to the electric mixing valve a is selected when the shower water is selected as the shower type and when the rain or mist shower is selected. By relatively changing by the amount corresponding to the difference in the sensible temperature, it is possible to always obtain the same sensible temperature regardless of the selection status of the shower type when the shower temperature is set to be the same.
