Abstract

The utility model discloses a household safety-voltage electrical shower device, which is characterized in that the utility model has simple structure, the product is highly safe and reliable for human bodies, and there is no need to install the water tank. On technology aspect, the production adopts a high-power transformer, a hypopiesia coil of the transformer is short-circuiting welded on the sheath of the screw hollow core discharge pipe, and the discharge pipe functionally is hollow core resistance wire. The utility model is applicable to family showers, which has the advantage of scientific and practical method, and also has extensive market and application prospect.

Description

Domestic safety voltage electric shower-bath

The utility model relates to a kind of household electrical appliance, especially relates to a kind of electric shower-bath that is used for family expenses.

In the present prior art, shower mainly is divided into two kinds of gas type and electroheating types.Gas shower is caused deaths repeatly, and both having made is to be transformed into forced-ventilatedly, also has fatal weakness in design.The electroheating type shower owing to directly use the 220V high voltage, also exists dangerous hidden danger.

The purpose of this utility model provides a kind of electric shower-bath to personal high safety, thoroughly reforms all disadvantages of gas type and electroheating type shower from design principle.

For achieving the above object, the solution that the utility model adopted is: the 220V supply voltage only enters the primary coil of high-power transformer, magnetic induction through transformer core acts on the low-voltage, high-current that the low-voltage coil generation is perfectly safe to the person, the low-voltage coil short circuit was welded on the crust of water pipe, and crossing on the water pipe function is the hollow resistance wire.

Since adopted above-mentioned design, electric shower-bath of the present utility model have simple in structure, product reliable to personal high safety, characteristics such as water tank need not be installed.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Accompanying drawing is a structural representation of the present utility model;

In the accompanying drawing: water inlet valve 1, hydraulic pressure control electric switch 2, spiral hollow are crossed water pipe 3, step down side coil windings 4, transformer core 5, the first wire-wound group 6 of transformer, are gone out sprinkler head 7, solder joint 8.

In the structure of the described present embodiment of accompanying drawing, running water is flowed into by water inlet valve 1, after hydraulic pressure reaches authorized pressure, hydraulic pressure control electric switch 2 is connected, the 220V line voltage enters the elementary winding 6 of high-power transformer, through the magnetic induction effect of transformer core 5, produce the low-voltage, high-current of 24V at low voltage winding in transformers winding 4.Low voltage winding in transformers winding 4 is welded on the spiral hollow by solder joint 8 short circuits and crosses on the crust at water pipe 3 two ends, crosses the not end of water pipe at the spiral hollow, connects shower and goes out sprinkler head 7.In use since the spiral hollow to cross water pipe 3 are passages that cold water flows through, in the process of current, can take away, and in process of flowing relaying temperature of continuing rising crossing the heat-flash that water pipe 3 sends.Repeat to be provided with earth point at low voltage winding in transformers winding 4, its effect is a human body and to cross water pipe 3, low-voltage coil winding 4, go out between the sprinkler head 7 be equipotential, and the highest drain voltage has only voltage on the low-voltage coil winding 4 half, is 12V in the present embodiment.Therefore, the utility model has guaranteed that from design principle the person is perfectly safe.

Claims

1, a kind of domestic safety voltage electric shower-bath, mainly by high-power transformer, hydraulic pressure control electric switch, go out parts such as sprinkler head and form; It is characterized in that: the short circuit of step down side coil windings is welded on the spiral hollow and crosses on the crust at water pipe two ends, crosses the water pipe end at the spiral hollow, connects shower and goes out sprinkler head.
