Abstract

The utility model discloses an automatical power off safety device for an electric heating water tap with no water current flowing. The safety device comprises a water inlet post, a valve and a water outlet, wherein a magnetic body is arranged in the water inlet post and sealed by a copper body; a circuit board reed switch or a magnetic control switch is attached to the upper end outside the water inlet post; and a water spraying post is arranged on the water inlet post. The automatical power off safety device for the electric heating water tap with no water current flowing has the benefit that the ohmic heating cannot be carried out if no differential pressure flows, that is, no water runs out from the water tap (no matter the water valve is closed or frozen) regardless of how much the water pressure is, so as to ensure safety of users.

Description

Electric hot water tap does not have the mobile automatic power outage security of current

Technical field

The utility model relates to a kind of electric hot water tap, little kitchen treasured or electric water heater, the pass water of particularly a kind of electric hot water tap, little kitchen treasured or electric water heater or the automatic power outage security of cutting off the water supply.

Background technique

The break-make electricity of existing market electric hot water tap is to control by hydraulic pressure switch, opens water valve, and hydraulic pressure backs down power switch and energising heating; Close water valve, pressure switch hydraulic pressure reduces power switch disconnection stopping heating; If when opening the water valve water outlet and blocking, still energising heating, the little water tank water temperature that is connected with tap can rise immediately, thereby makes plastic distortion even leak and get into electric component and cause electric leakage dangerous.If when the cold area water tap is freezing, same very dangerous, so the time hydraulic pressure switch water channel in water freezing expand and back down the power switch heating, and cause dry combustion method, excess temperature leaks, and causes fire when serious.

Summary of the invention

To the shortcoming of existing electric hot water tap, the utility model provides a kind of novel electric hot water tap not have the mobile automatic power outage security of current.

To achieve these goals, the measure taked of the utility model is:

A kind of electric hot water tap does not have the mobile automatic power outage security of current; Comprise inflow column, valve and water outlet, place magnet in the inflow column, magnet is sealed with the copper body; A circuit board dry reed-pipe or magnetic switch are pasted in the outer upper end of inflow column, and a water jet column is installed on the inflow column.

1. forceful electric power is directly controlled:

A magnet is installed in the water jet column upper end in inflow column, and a magnetic switch is installed in the inflow column outside in magnet corresponding part, and the manual heating switch of connecting.When water valve was opened, magnet moved the aligning magnetic switch under the effect of water, and do not heat during pass if the manual heating switch is opened just heating switch on this moment under the effect of magnetic force.If the user forgets that closing heater switch needs only shutoff valve, hydraulic action disappearance magnet self gravitation sinks, and magnetic switch magnetic force disappearance switch opens circuit breaker stops heating.Magnetic switch also is to break off if water supply is cut off the water in addition; In like manner freezing also is that anhydrous magnetic switch also is to break off, and magnetic switch also was to break off when and for example water outlet was blocked, therefore no matter heating takes place can not switch on which kind of situation; Has only ability proper functioning under the normal condition, so stopped hidden danger.See electrical schematic 2 for details.

2. light current control:

A magnet is installed in the water jet column upper end in inflow column; A dry reed-pipe element and the manual heating switch of connecting are installed in the inflow column outside, magnet corresponding part; The forceful electric power place adorns a crystal switch (controllable silicon), and dry reed-pipe and manual heating switch are controlled the break-make of crystal switch.When water valve is opened; Magnet moves the aligning dry reed-pipe under the effect of water; The logical heater switch in dry reed-pipe road is opened and is impelled the controllable silicon path to begin heating under the effect of magnetic force, if close heater switch controllable silicon disconnection stopping heating, or only bars up water valve; Falling dry reed-pipe under the magnet does not have magnetic force and breaks off controllable silicon disconnection stopping heating.See electrical schematic 3 for details.

Comprise inflow column, valve and water outlet, place magnet in the inflow column, magnet is sealed with the copper body, and a dry reed-pipe is pasted in the outer upper end of inflow column; A water jet column is installed in the inflow column, and when water valve was opened, the water jet column water spray rushed to magnet and dry reed-pipe and neat, under the magnetic force; The reed switch conduction signal is given controllable silicon, and controllable silicon energized and heating bars up water valve; Water jet column stops water spray, and the self gravitation effect sinking of magnet separates with dry reed-pipe, and this moment, dry reed-pipe broke off; The controllable silicon deenergization stops heating, accomplishes that not water outlet can't switch on, and realizes purpose of safety.

The beneficial effect of the utility model: no matter the utility model is hydraulic pressure height, as long as no pressure reduction flows, not water outlet of water tap just (regardless of being that water valve bars up or the freezing) heating of just can't switching on ensures safety like this.

Embodiment

Like Fig. 1, a kind of electric hot water tap stream power outage security of cutting off the water comprises inflow column 1, valve 2 and water outlet 3; Place magnet 6 in the inflow column 1; Magnet 6 usefulness copper bodies 8 are sealed, and a circuit board dry reed-pipe 4 is pasted in inflow column 1 outer upper end, water jet column shelves is installed in the inflow column 1 is lived magnet.When water valve was opened, the water jet column water spray rushed to magnet and dry reed-pipe and neat, under the magnetic force; Reed switch conduction is controlled the controllable silicon energized and is heated, and bars up water valve, and water jet column stops water spray; The self gravitation effect of magnet sinks to separating with dry reed-pipe down; Dry reed-pipe broke off control controllable silicon deenergization and stopped heating this moment, accomplished that not water outlet can't switch on, and realized purpose of safety.

Like Fig. 2, the direct control circuit schematic representation of a kind of forceful electric power comprises load 9, hand switch 10, magnetic switch 11 and magnet 6; When water valve was opened, the water jet column water spray rushed to magnet 6 and magnetic switch and neat, and magnetic switch is opened under the magnetic force; Just begin heating if hand switch is opened this moment, and when water valve barred up, magnet sank to separating with magnetic switch; Magnetic switch is closed, and heating stops, and accomplishes to cut off the water and electricity supply.

Like Fig. 3, a kind of weak control circuit schematic representation comprises load 9, controllable silicon 13, hand switch 10, dry reed-pipe 12 and magnet 6, circuit board 5; When water valve was opened, the water jet column water spray rushed to magnet 6 and dry reed-pipe 12 and neat, dry reed-pipe 12 conductings under the magnetic force; Begin heating if hand switch is opened controllable silicon 13 conductings this moment, and when water valve barred up, magnet sank to separating with dry reed-pipe 12; Dry reed-pipe 12 opens circuit, and controllable silicon 13 is closed and stopped heating, effectively guarantees user security.
