The utility model discloses a directly-heated water heating device, wherein two or more heating pipes connected in series are arranged in a housing; the housing is opened with a water inlet; one end of the heating pipe is arranged on the inner cavity of the housing and is communicated with the inner cavity thereof; the other end of the heating pipe is a water outlet. In the water heating device, the running water directly-heated heating mode is adopted, thereby avoiding repetitive water heating or hot and cold water mixed heating; therefore, the water is fresh and sanitary, which has no pollution; the heating pipe has compact structure, good heating effect and high water outlet temperature; in addition, the temperature of the outside of the device is low, thereby being safety, reliable, energy-saving and fast.
Description
Technical field
The utility model relates to liquid heating, relates in particular to the directly-heated type hot-water heating system, specifically a kind of directly-heated energy-saving electric heater unit.This device is specially adapted to the use in water dispenser, water heater or the boiling water machine, also can be applicable to the heating of other working fluid.
Background technology
Existing liquid heating as the water dispenser heater, mostly adopts the storage water heater heating.Its structure is in a water storage tank electrothermal tube to be set, the water in the water storage tank heated, and the switch by temperature controller control power supply, make electrothermal tube gap break-make, keep in the scope of water temperature between 90 ℃～97 ℃ in the water storage tank.The heater of this structure, for guaranteeing not dry combustion method of electrothermal tube, the water in the water storage tank must remain on full state.The user connect discharge water after, at once will inject cold water.Therefore, always some water remains in the water storage tank and is heated repeatedly and remain on the condition of high temperature, and people's health and health is caused a hidden trouble.Its another shortcoming is in order to keep the water temperature in the water storage tank, and electrothermal tube is work often, thereby takes.
Summary of the invention
Of the present utility model what will solve is the problems referred to above that present technology exists, and aims to provide a kind of safety and sanitation and energy-conservation novel electric heater unit.
The technical scheme that addresses the above problem employing is: the directly-heated type hot-water heating system, be provided with the heating tube of two or many series connection in the shell, offer water inlet on the shell, described heating tube one end place shell inner cavity top and with its conducting, the other end is a delivery port.
Hot-water heating system of the present utility model, its course of work is as follows:
1, water flows into from the water inlet of shell, up to water completely to the upper end, in this flow process, flowing water has absorbed the waste heat that the heating tube outside comes out, not only keep the low-temperature condition of crust of the device, improved device ', and realized preheating first of water, both improve water temperature, reduced the loss of energy again.
2, when water during completely to the upper end, by heating tube one end entrance inflow pipe inner chamber, the inner chamber of body is smooth nonmetallic materials, water is less scaling therein, and the contact-making surface of electrical heating elements and body is big, and heat-conducting effect is better, water is rapidly heated therein, has higher efficient.
Further heated when 3, Dang Shui enters into second heating tube, during to delivery port, can have been reached the requirement and the standard of water temperature.
By last surface analysis as can be known, hot-water heating system of the present utility model has been because of having taked flowing water directly-heated type mode of heating, and that has avoided water repeats heating or hot and cold water Hybrid Heating phenomenon, and water is fresh, and health is pollution-free; Heating tube syndeton compactness, heat effective, the leaving water temperature height, the appearance temperature of device is low, accomplishes safe, reliable, energy-conservation, quick.
Another advantage of the present utility model is, the terminal of two or many electric heating tubes can be drawn respectively, every electric heating tube can be an equal-wattage, also can form by the electric heating tube of different capacity, like this, the water of delivery port both can be warm water as required, can be hot water or boiling water also, had improved the temperature setting range of delivery port; Simultaneously, the external circuit controller can be controlled separately every heating tube, for the current of different flow and flow velocity, has improved the degree of accuracy of delivery port design temperature, has strengthened the controllability and the control effect of water temperature.
As further improvement of the utility model, connect conducting by " U " shape tube connector between the adjacent heating tube.When water arrives delivery port through each root heating tube, the mobile distance and the time of the water that extended, help improving rate of heat exchange.
Further improve as of the present utility model, described heating tube is surrounded by insulating sleeve outward.The insulating sleeve two ends seal by quartz socket tube.Not only make the water in electrical heating elements and the shell isolate fully, heater is safe and reliable, and the terminal of two electric heating tubes can draw respectively, is convenient to the control of external circuit controller, for the current of different flow and flow velocity, improved the controllability and the control effect of water temperature.
According to the utility model, described heating tube can be electrothermal film heating pipe, promptly in the sticking obedient Electric radiant Heating Film in the outside of heating tube.Described heating tube also can be the heating wire heating tube, promptly at the outside of heating tube coiling heating wire.
According to the utility model, described shell can be an overall structure, also can be one package structual.Adopt latter's structure, shell comprises shell block and loam cake, is provided with sealing ring between shell block and loam cake.Easily shell also can be made of shell block and bottom or side cover.
Further improve as of the present utility model, described outer casing bottom is provided with discharge outlet again, can drain the water in the shell when cleaning.

The specific embodiment
With reference to Fig. 1-4, directly-heated type hot-water heating system of the present utility model, shell block 7 and upper plastic cover 10 that shell is made by the PP plastics constitute, between shell block 7 and loam cake 10, be provided with silica gel sealing ring 1, vertically be provided with two electrothermal film heating pipes 4,9 in the shell block 7, shell block 7 bottoms offer water inlet B and discharge outlet C.The upper end of described electrothermal film heating pipe 4 place shell block 7 inner chambers top and with its conducting, the lower end is communicated with the lower end of first electrothermal film heating pipe 9 by a U-shaped silicone tube 8, the upper end of electrothermal film heating pipe 9 passes loam cake 10, this port is delivery port D.
Be surrounded by insulating sleeve 5 outside the described electrothermal film heating pipe 4,9, the water in Electric radiant Heating Film and the shell block inner chamber is isolated fully.Insulating sleeve 5 two ends are by quartz socket tube 3,6 sealings, and the terminal 11 of two electric heating tubes is drawn from the quartz socket tube 3 on top respectively.
What should be understood that is: the foregoing description is just to explanation of the present utility model, rather than to restriction of the present utility model, on spiritual basis of the present utility model, those skilled in the art can conversion go out numerous embodiments, as adopt the heating tube of three series connection, all adopt the conducting of U-shaped tube connector between each heating tube, the terminal delivery port of the 3rd electrothermal tube is drawn downwards.Perhaps, direct three heating tubes are connected into U-shaped.Thus, can also derive the way of example of many heating tubes successively.And for example delivery port can be drawn from shell by adapter coupling.And for example water inlet can be opened on the sidewall of shell block 7, only guarantees that its water inlet that highly is lower than first electrothermal tube gets final product.Therefore, any utility model that does not exceed in the utility model connotation scope is created, and all falls within the protection domain of the present utility model.
