Abstract
The utility model discloses a quick heating type electric water heater which can prevent positive current leakage and negative current leakage, and comprises a plastic casing body. A heating body and a computer controller are installed inside the plastic casing body, a water inlet pipe is connected at the lower end of the heating body, and a water outlet pipe is connected at the upper end of the heating body, the other end of the water inlet pipe and the other end of the water outlet pipe are respectively connected with a water inlet nozzle and a water outlet nozzle, a metal grill is installed on the inner side of the lower part of the plastic casing body, and the metal grill is respectively connected with a computer controller and a ground wire through conducting wires. Because the metal grill is installed on the inner side of the lower part of the plastic casing body and reliably earthed, thus no matter the positive current leakage or the negative current leakage happens, if only a 36 V voltage is formed on the metal grill, the current leakage protector of the computer controller connected with the metal grill cuts off a power supply and alarms, and the component part under the water outlet part still keeps in the no-electricity state, thereby, the utilization safety of the user is ensured.
Description
Technical field
The utility model relates to the quick-heating type electric water heater field, relate in particular to a kind of anti-just, the quick-heating type electric water heater of converse electrical leakage.
Background technology
At present, in the quick-heating type electric water heater industry, the problem that the user at first is concerned about is the Electrical Safety problem, because when bathing, whole body all is a water, and resistance is very low, and some leakage currents are arranged, and just Danger Electric shock risk may take place.The electric leakage form comprises forward electric leakage and converse electrical leakage; the forward electric leakage mainly is that electric component breaks down and unreliable causing of earth leakage protective device leaks electricity; converse electrical leakage mainly is that ground wire electrification and running water pipe are charged, and the electric heater of high-performance earth leakage protective device is housed, and the probability that the forward electric leakage takes place is very little; on the contrary; because of Chinese power utilization environment problem, the ground connection of many buildings is insecure, or even disappearance; in this case, converse electrical leakage becomes the focus that solves safety problem.And the proof and electric leakage-proof safety device mainly is the passive type protection now, promptly reduces the electric current by human body as far as possible, rather than the generation electric leakage is promptly cut off the electricity supply.Now; up-to-date proof and electric leakage-proof safety device mainly is to be the charged water resistance method " Fang Dianqiang " of representative with the Haier; promptly be by increasing by one section plastic tube at inlet tube and outlet tube; in case utilize the principle of water resistance to reach the purpose that reduces the delivery port electric current when leaking electricity danger is arranged; and this type of protective device can not guarantee absolute safety; because though though the delivery port electric current reduces; but some metal parts that easily touch also might be charged; so still there is very big potential safety hazard in dangerous not elimination.
The utility model content
Technical problem to be solved in the utility model provides and is a kind ofly just solving more reliably, simultaneously, the converse electrical leakage problem anti-just, the quick-heating type electric water heater of converse electrical leakage.
For solving the problems of the technologies described above, the technical solution of the utility model is: anti-just, the quick-heating type electric water heater of converse electrical leakage, comprise plastic casing, calandria and computer controller are installed in the described plastic casing, described calandria lower end is connected with water inlet pipe, the upper end is connected with outlet pipe, the described water inlet pipe and the outlet pipe other end are connected with water inlet tap and faucet respectively, described plastic casing lower inside is equipped with metallic grid, and described metallic grid links to each other with ground wire with computer controller respectively by lead.
As a kind of improvement, described water inlet pipe links to each other with ground wire respectively by lead with outlet pipe.
As further improvement, described water inlet tap and faucet are used damping.
Adopted technique scheme, the beneficial effects of the utility model are: anti-just, the quick-heating type electric water heater of converse electrical leakage, comprise plastic casing, calandria and computer controller are installed in the described plastic casing, described calandria lower end is connected with water inlet pipe, the upper end is connected with outlet pipe, the described water inlet pipe and the outlet pipe other end are connected with water inlet tap and faucet respectively, described plastic casing lower inside is equipped with metallic grid, and described metallic grid links to each other with ground wire with computer controller respectively by lead.Because the plastic casing lower inside is equipped with metallic grid; and metallic grid by lead respectively with computer controller with link to each other with ground wire; so metallic grid is in the reliable ground state constantly; no matter be the forward electric leakage; still converse electrical leakage is higher than 36 volts voltage as long as metallic grid formed, and with earth leakage protective device on the computer controller that metallic grid links to each other action power dump just takes place; make to remain electroless state below the delivery port, thereby guaranteed that the user's is safe in utilization.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
The specific embodiment
Anti-just, the quick-heating type electric water heater of converse electrical leakage, as shown in drawings, comprise plastic casing 1, calandria 2 and computer controller 3 are installed in the plastic casing 1, calandria 2 lower ends are connected with water inlet pipe 7, the upper end is connected with outlet pipe 8, the water inlet pipe 7 and outlet pipe 8 other ends are connected with water inlet tap 4 and faucet 5 respectively, plastic casing 1 lower inside is equipped with metallic grid 6, metallic grid 6 links to each other with ground wire with computer controller 3 respectively by lead, and water inlet pipe 7 links to each other with ground wire respectively by lead with outlet pipe 8.
Its operation principle is: if the forward electric leakage takes place; the situation that occurs leaking as calandria 2; the water of machine intimate may just have the voltage of 220V at this moment; because whole metallic grid 6 has the anti-leak protection effect; and play the effect of reference voltage point; as long as it is charged in the water; this metallic grid 6 of must flowing through; when leakage point is higher than 36 volts voltage to these metallic grid 6 formation; cut off calandria 2 power supplys with the anti-forward leakage circuit action on the computer controller 3 that metallic grid 6 links to each other; machine quits work, and can't start and the alarm user.
If converse electrical leakage takes place, make ground wire electrification as if reasons such as or finishing wrong lines bad because of other electric property this moment, because whole special metallic grid 6 ground connection should be in electroless state, occur having when being higher than 36 volts voltage suddenly, cut off calandria 2 power supplys with the anti-reverse leakage circuit action on the computer controller 3 that metallic grid 6 links to each other, machine quits work, and can't start and the alarm user.
So no matter under which kind of situation, the following position of delivery port remains electroless state, really reach anti-just, the converse electrical leakage defencive function, can guarantee user's personal safety in use.
More than said metallic grid 6, be not limited in metallic grid, other conductor also can reach the effect of this device.
