Abstract
The utility model provides a safety connection water pipe. Two safety connection water pipes respectively connect the water inlet and the water outlet as well as the water mixing valve of a water-storing type electric water heater. Certain water-storing type electric water heater separates the water to other water valves. The safety connection water pipe is made of plastic, with small inner diameter and length matching the inner diameter. With small diameter, the length of the safety connection water pipe can be shortened, with large diameter, the length of the safety connection water pipe can be lengthened, so as to make the water flowing through the of the safety connection water pipe have extremely large resistance valve. Even if the electric water heater has creepage, the current of the alternating power through the water mixing valve with water and other water valves are very small, promising no danger to personal safety. The utility model is characterized by reasonable design, easy machining, and convenient operation, etc.
Description
The utility model relates to a kind of connection water pipe that is applicable to electric heater.
Present electric heater, the power supply of employing are the 220V AC powers, and alternating current raises the electric heater temperature by electric heater, and water is heated.Though take multiple measure to prevent electric leakage when making electric heater, the leaky of electric heater still can not be stopped fully.In a single day electric heater leaks electricity, alternating current flows through the health that uses the hot water personnel by water; Sometimes, though the electric heater leakproof, the circuit electric leakage of electric heater, alternating current also might flow through the health that uses the hot water personnel through water.Either way electric shock accidents can take place below.All electric heaters all require to take reliable earthing or grounding means at present, prevent that electric shock accidents from taking place.But because the early stage part dwelling house of China is not installed ground wire, though the dwelling house of later stage building is equipped with ground wire, but quality is not very reliable, sometimes can not bring into play due effect,, happen occasionally owing to electric shock accidents takes place for the electric leakage of electric heater so use the personnel of electric heater.
The purpose of this utility model is thoroughly to solve the electric shock accidents that the electric leakage owing to electric heater takes place, even do not having also to guarantee to use electric heater personnel's personal safety under the insecure situation of ground wire or ground wire device.
The purpose of this utility model realizes in the following manner.Each is connected to the mixed water valve of hot and cold water with a metal tube water inlet of present water-storage electric heater and delivery port, and hot and cold water mixes water valve cold water and hot water are mixed into the suitable warm water of temperature, delivers to shower head through flexible pipe.If water-storage electric heater electric leakage, advance with electric heater, metal tube that outlet pipe connects and hot and cold water mix water valve and all can conduct electricity, mixing the mixed warm water of water valve also conducts electricity, human body just contacts with warm water, and electric shock accidents may take place, change into nonconducting plastic tube if will connect electric heater with the metal tube that hot and cold water mixes water valve, and the internal diameter of plastic tube is very little, the length and the internal diameter of plastic tube are complementary, internal diameter is little, contraction in length some, internal diameter is big, length lengthening, the current of the feasible plastic tube of flowing through have sizable resistance value, even electric heater leaks electricity, the 220V AC power is also very little through the electric current that water flows to the mixed water valve of hot and cold water, is lower than safety value, electric shock accidents can not take place, jeopardize personal safety.The water-storage electric heater that has also is diverted to other penstock from delivery port, connect water pipe with safety-type, can guarantee that all are safe with water spot.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is the utility model and water-storage electric heater connection diagram.
Safety-type connection water pipe to electric heater of the present utility model elaborates in conjunction with the accompanying drawings.
Among the figure, safety-type connects water pipe and is made up of attaching nut (1), rubber blanket (2), plastic water pipe (3).Connect water pipe with two safety-types and respectively the mixed water valve of water inlet, delivery port and the hot and cold water of water-storage electric heater is coupled together, the water-storage electric heater that has also flows to moisture other penstock.The internal diameter of plastic tube (3) is very little, for 1mm to 26mm, the length of plastic tube (3) should be complementary with internal diameter, for 10mm to 20000mm, internal diameter is little, length can shorten, internal diameter is big, and length will extend, and the current of the feasible plastic tube (3) of flowing through have sizable resistance value, plastic tube (3) is made of plastics non-conductive, even electric heater leaks electricity, the 220V AC power is also very little through the electric current that water flows to the mixed water valve of hot and cold water and other penstock, is lower than safety value, electric shock accidents can not take place, jeopardize personal safety.The electric heater of other type also can couple together with water inlet, delivery port and various penstock, the water appliance of safety-type connection water pipe of the present utility model with electric heater, guarantees user of service's safety.
Embodiment
A kind of safety-type that connects electric heater of the present utility model connects water pipe to be compared with existing technology, have reasonable in design, be easy to processing, characteristics such as easy to use, excellent popularization use value is arranged.
Except that this specification These characteristics, be the known technology of those skilled in the art.
