Abstract
The utility model discloses an efficient instant electric water heater. The efficient instant electric water heater comprises a container and a heating unit, wherein the heating unit is a flat heating wire, the container is provided with a water inlet and a water outlet, a plurality of winding rods capable of being wound with the heating wire are arranged in the container, the surface of the heating wire is coated with an insulating layer, and the heating wire is connected with an external circuit through a screw locking structure arranged on the container. The area of the section of the flat heating wire is small, resistance is large, a heating value is high, the heating area of the heating wire is large, and therefore the heated area of water flow is enlarged, and heating efficiency is effectively improved.
Description
Technical field
The utility model relates to electric heater technical field, especially a kind of efficient instant electric water heater.
Background technology
During electric water heater heating, be to utilize to be arranged on its inner heating tube and to heat, the inside of heating tube is heating wire, can produce heat and heat, because heating-pipe structure is complicated after energising, long-term use can be oxidized and easily burns out heater strip or leak electricity, and service life is short.And existing instant electric water heater is in order to improve the efficiency of heating surface, be typically provided with a high-power heater, because power is very large, energy consumption is higher, and structure is also complicated, so this type of instant electric water heater's security is also usually under suspicion.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of efficient instant electric water heater, adopts the heating wire of flat structure as heating unit, directly current is heated, and the efficiency of heating surface is high.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of efficient instant electric water heater, comprise container and heating unit, described heating unit is flat heating wire, container be provided with water inlet and delivery port and its inside be provided with some can be wound around for heating wire around bar, described heating wire surface scribbles insulating barrier, and it is fixed on container and is connected with external circuit by the tight lock construction of screw rod arranging.
As the further improvement of technique scheme, describedly around bar, be provided with for blocking the fixedly draw-in groove of heating wire.
As the further improvement of technique scheme, the tight lock construction of described screw rod is high-temperature insulation air locking.
As the further improvement of technique scheme, described insulating barrier is polytrifluorochloroethylene.
The beneficial effects of the utility model: the utility model adopts the heating wire of flat structure as heating element heater, by by heating wire around current are directly heated on bar in water heater container, because the area of section of flat heating wire is little, resistance is large, so its caloric value is high, and its heating area is also large, the heating surface area of current is strengthened, and effectively improves the efficiency of heating surface, and this instant electric water heater's is simple and reliable for structure, safe, there is lower production cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further.
Fig. 1 is the schematic diagram of heating wire in the utility model.
Fig. 2 is the helical structure schematic diagram of heating wire in the utility model.
The specific embodiment
With reference to Fig. 1, a kind of efficient instant electric water heater that the utility model provides, comprise container and heating unit, described heating unit is flat heating wire 1, container be provided with water inlet and delivery port and its inside be provided with some can be wound around for heating wire 1 around bar, described heating wire 1 surface scribbles insulating barrier, it is connected with external circuit by the tight lock construction of screw rod arranging on container, the tight lock construction of described screw rod is high-temperature insulation air locking, when heating wire 1 external power supply circuits, not only can prevent electric leakage but also play good sealing function, because the area of section of the flat heating wire 1 adopting in the utility model is little, resistance is large, caloric value is high, and its heating area is also large, the heating surface area of current is strengthened, effectively improve the efficiency of heating surface.
In said structure, describedly around bar, be provided with for blocking the fixedly draw-in groove of heating wire 1, with reference to the structure chart shown in Fig. 2, heating wire 1 can be stuck in draw-in groove by turning to helical structure, and Stability Analysis of Structures is firm.
Preferably, described insulating barrier is polytrifluorochloroethylene, has good chemical stability, insulating properties and heat-resisting quantity, effectively protects heating wire 1, improves the service life of water heater.
The utility model adopts the heating wire 1 of flat structure as heating element heater, by by heating wire 1 around current are directly heated on bar in water heater container, according to the heating capacity requirement of water heater, take segmented that the arrangement architecture of heating wire 1 is set.During work, current flow in container from water inlet, and heating wire 1 one energisings can produce heat fast heats water body, and simple and reliable for structure, the efficiency of heating surface is high.
The above, be preferred embodiment of the present utility model, and the utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection domain of the present utility model.
