Abstract

The utility model discloses an instant water heater which comprises a water inlet pipe, a heating part and a water outlet pipe. The water inlet pipe and the water outlet pipe are connected with the heating part, a check valve is arranged on the water inlet pipe, when water flow flows to the heating part from the water inlet pipe, the check valve is opened, and when the water flow flows to the water inlet pipe from the heating part, the check valve is closed. The instant water heater has the advantages that forward flowing and reverse stopping of tap water entering the water heater are achieved by means of the check valve, the water in the heating part is prevented from flowing reversely and outward and causing dry burning when a water supply is cut off, the service life of the heating part can be effectively prolonged, safety and reliability of the water heater are guaranteed, and the instant water heater is simple and compact in structure and convenient to disassemble and assemble.

Description

Immediately heating water heater

Technical field

The utility model relates to water heater, relates in particular to a kind of immediately heating water heater.

Background technology

The instant electric water heater who uses on the market at present, before being mainly divided into, open formula with after open two kinds of formulas, the front formula that opens also claims outlet open-type, water valve is installed on the water inlet of machine, can only, for bathing, can not multichannel supply water.Then open formula type, also referred to as port closing formula, water valve is arranged on the water outlet of machine, and this water heater can multichannel supply water, very convenient use.But when user family cuts off the water supply; because water inlet does not have valve switch; water in instant electric water heater's inner heat parts can flow backwards, and causes heating cup lack of water, again during water easily because the air having in water route causes dry combustion method and causes electric heater protection or fault.

Utility model content

The technical problem that the utility model mainly solves is to provide a kind of immediately heating water heater, opens formula and with the stop valve that prevents dry combustion method after employing.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of immediately heating water heater is provided, comprise water inlet pipe, heat generating components and outlet pipe, described water inlet pipe and outlet pipe are connected to respectively described heat generating components, on described water inlet pipe, stop valve is installed, when current flow to heat generating components from water inlet pipe, described stop valve conducting, when current flow to water inlet pipe from heat generating components, stop valve is closed.

Wherein, described stop valve comprises stop valve body, be positioned at stop valve opening and at least two support columns that are arranged symmetrically with on stop valve body centered by stop valve opening, the top of described support column is fixed with the spring fixed seat being positioned at directly over described stop valve opening, the outer ring sleeve of described spring fixed seat is connected to the spring towards stop valve opening, on spring fixed seat, have a through hole, in described through hole, be provided with slidably a motion bar, the top of described motion bar is provided with the plug that can seal stop valve opening, under the support of described spring, described motion bar extends stop valve opening part and is sealed by plug, stop valve opening is connected to outside tap water pipe line.

Wherein, be extended with the protruding lip of a circle on the inwall of described stop valve opening to center, described plug relies on the elastic compression of described spring on described protruding lip.

The beneficial effects of the utility model are: adopt stop valve to make to enter running water forward conduction, the backward stop of water heater, the dry combustion method that the outside adverse current of water while preventing from cutting off the water in heat generating components causes, can effectively extend the life-span of heat generating components, guarantee that water heater safety is reliable, simple in structure, compact, easy accessibility.

Fig. 1 is the structure chart of immediately heating water heater of the present utility model;

Fig. 2 is the structure chart of stop valve of the present utility model when normal water inlet state;

Fig. 3 is the structure chart of stop valve of the present utility model when cutting off the water supply state.

Main element symbol description: 1, stop valve; 11, stop valve body; 12, stop valve opening; 121, protruding lip; 13, support column; 14, spring fixed seat; 15, spring; 16, motion bar; 161, plug; 2, water inlet pipe; 3, heat generating components; 4, outlet pipe.

The specific embodiment

By describing technology contents of the present utility model, structural feature in detail, being realized object and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.

Refer to Fig. 1, the immediately heating water heater of present embodiment comprises water inlet pipe 2, heat generating components 3 and outlet pipe 4, described water inlet pipe 2 and outlet pipe 4 are connected to respectively described heat generating components 3, heat generating components 3 is cup-shaped, inside is provided with heater element can heat water, on described water inlet pipe 2, stop valve 1 is installed.

Refer to Fig. 2 and Fig. 3, described stop valve 1 comprises stop valve body 11, be positioned at stop valve opening 12 and four support columns that are arranged symmetrically with 13 on stop valve body 11 centered by stop valve opening 12, on the inwall of described stop valve opening 12, to center, be extended with the protruding lip 121 of a circle, the top of described support column 13 is fixed with the spring fixed seat 14 being positioned at directly over described stop valve opening 12, the outer ring sleeve of described spring fixed seat 14 is connected to the spring 15 towards stop valve opening, on spring fixed seat 14, have a through hole, in described through hole, be provided with slidably a motion bar 16, the top of described motion bar 16 is provided with the plug 161 that can seal stop valve opening 12, under the support of described spring 15, the plug 161 of motion bar 16 extends in stop valve opening 12 and is pressed on protruding lip 121 12 sealings of stop valve opening.Stop valve opening 12 is connected to outside tap water pipe line, and when current flow to heat generating components 3 from water inlet pipe 2, Water Pressure is on plug 161, make plug 161 Compress Springs 15, motion bar 16 is to after-contraction, stop valve 1 conducting, and current can flow in heat generating components 3 smoothly; While causing the flow direction water inlet pipe 2 in heat generating components 3 when cutting off the water, Water Pressure is at the another side of plug 161, under the effect of hydraulic pressure and spring force, motion bar 16 stretches out downwards on the protruding lip 121 that makes plug 161 be pressed on stop valve opening 12, and stop valve 1 is closed.

The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
