Abstract
The utility model discloses a water inlet pipe of an electric water heater, which mainly consists of a water inlet pipe and a connecting body, wherein the water inlet pipe can be fixedly connected into the connecting body, and a plurality of inclined guide holes are arranged on the side surface of the water inlet pipe and are downwards inclined by using the installing and use directions as references. The misoperation frequency of a tripolar power-off type current leakage protection plug can be greatly reduced through the water inlet pipe, and in addition, the water heater output rate of the electric water heater can be improved, so the energy efficiency coefficient of the electric water heater is improved.
Description
Technical field
The utility model relates to a kind of electric heater water inlet pipe, is used to be installed in the electric heater, belongs to the water inlet system accessory of electric heater.
Background technology
China's electrical network is mainly the TN-C power utilization network; belong to the connection type of protecting connecting to neutral; it is the mode that zero line and ground wire adopt the far-end short circuit; and three utmost point outage type earth leakage protective devices; its ground wire has independent testing circuit; power supply is usually by the mode inlet wire of getting its single phase poaer supply in the three phase mains in the user family; and three phase mains distributes how tame user; when a certain phase power source loads is uneven; make the neutral conductor (zero line) produce impedance voltage drop; thereby cause neutral point drifting, this moment, ground wire just has electric current to be passed through because zero line communicates with ground wire; if and the water heater installation pipeline is a metal tube; electric current will constitute the loop to metal tube through ground wire, and this electric current is detected and Lou protects is action protection, causes inconvenience greatly for client's use.
Summary of the invention
In order to overcome above-mentioned defective; the utility model provides a kind of electric heater water inlet pipe; this water inlet pipe not only can reduce the misoperation frequency of three utmost point outage type leakage protecting plugs greatly, and can improve the water heater output rating of electric heater, thereby improves the efficiency coefficient of electric heater.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of electric heater water inlet pipe, mainly form by water inlet pipe and connected body, water inlet pipe can be fixedly connected in the connected body, the water inlet pipe side is provided with the pilot hole of several inclinations, to install and use direction is benchmark, and it is downward-sloping that pilot hole is.
As optimal way of the present utility model, the angle of the radial section of described pilot hole and described water inlet pipe is 15～89 °.
As further improvement of the utility model, described pilot hole is one of square hole, circular hole and elliptical aperture.
As further improvement of the utility model, described water inlet pipe is a plastic tube.
The beneficial effects of the utility model are: by the pilot hole control water (flow) direction of several inclinations is set on water inlet pipe, direction and speed when slowing down cold water into make mixed hot and cold water layering obvious, thereby improve the hot water delivery rate of electric heater; By the plastic-metal pipe is set, can reduce the misoperation frequency of three utmost point outage type leakage protecting plugs.
