Abstract
The utility model relates to a leakage protector and solves the potential hazard that the current leakage protector on the electrical massaging foot basin possibly cannot operate or radically cannot operate; the reliable leakage protection grounding device for the electrical massaging foot basin is characterized in that: one or a plurality of metal or conductive rubber piece(s) with good conductivity is or are mounted at the bottom or the water-dipping part of the electrical massaging foot basin, the metal or conductive rubber piece(s) is or are connected with the earth terminal of the three-phase power cord of the electrical massaging foot basin by conducting wires.
Description
Technical field
The utility model relates to earth leakage protective device, particularly leakage protection grounding device of electronic massage footbath.
Technical background
Earth leakage protective device is widely used in every field the sixth of the twelve Earthly Branches; to the great role of having sent out brightness of personal device security; but exist a little power consumption equipments of order and particularly also exist the not working hidden danger of earth leakage protective possibility on the electronic massage footbath; the therapeutic massage foot soaking and washing spreads all over all small towns, city, the whole nation the sixth of the twelve Earthly Branches; all there is every day ten million people to steep the pin massage, exists very big potential safety hazard.
Summary of the invention
The purpose of this utility model is at above-mentioned defective, and a kind of reliable leakage protection grounding device of electronic massage footbath is provided.
The technical solution of the utility model is an electronic massage footbath electric leakage earth protective device; it is characterized in that the electronic massage footbath earth protective device is that one or more conduction good metal or conductive rubber are installed in the position that maybe can be dipped into water in the electronic massage footbath bottom, this metal or conductive rubber have the earth terminal of earth leakage protective electronic massage footbath power line single-phase three-wire plug or connect good earth connection with the lead connection.
Description of drawings
Accompanying drawing is a leakage protection grounding device of electronic massage footbath structural principle schematic diagram.
1 electronic massage footbath, 2 earth leakage protective devices, 3 single-phase three-wire plugs, 4 leads, 5 metals among the figure.
Earth leakage protective device 2 is installed in electronic massage footbath 1 inside or is installed on the power line or with single-phase three-wire plug 3 and is combined into one in the accompanying drawing.
Specific embodiments
The utility model leakage protection grounding device of electronic massage footbath is at electronic massage footbath (1) end
One or more conduction good metal (5) or conductive rubber (5) are installed in the position that is dipped into water, and this metal (5) or conductive rubber (5) connect the earth terminal of electronic massage footbath (1) the power line single-phase three-wire plug (3) with earth leakage protective (2) or connect good earth connection with lead (4).
Operation principle:
Existing electronic massage footbath all exists the not working hidden danger of earth leakage protective possibility; reason is that earth leakage protective principle is that the live wire of single phase poaer supply and ground wire are with being through in the through wires hole of a current transformer; under the normal condition; the live wire electric current equates through the electric current that loads to ground wire; electric current one-in-and-one-out direction is opposite in current transformer; the electric current of cancelling out each other equals zero, and the Current Transformer Secondary electric current also is zero, and earth leakage protective can not moved outage.Break when electric leakage when heating tube occurring; because electronic massage footbath mostly is that plastic casing is not connected with running water pipe; insulate with the earth; water in the basin will produce electric potential gradient, and live wire equates still that with the electric current of ground wire earth leakage protective is inoperative; if the human body both feet are placed in the basin; human body and the earth also insulate, and the both feet potential difference of water down will make the people get an electric shock, and earth leakage protective is still inoperative.The utility model is that a conduction good metal or conductive rubber are installed in the position that maybe can be dipped into water in the electronic massage footbath bottom; this metal or conductive rubber connection have the earth terminal of earth leakage protective electronic massage footbath power line single-phase three-wire plug or connect good earth connection; at this moment above-mentioned situation appears again; charged water constitutes the loop by metal earth and the earth of installing; part live wire electric current is directly got back to ground wire without earth leakage protective current transformer; no longer equal zero after the payment of two current in wire in the current transformer hole; the Current Transformer Secondary electric current also no longer equals zero; secondary current is through amplifying control switch tripping operation outage, and personal equipment has all obtained protection.
