Abstract
The utility model provides an electric heating device for water heater, which has a casing made of insulation material. One side of the casing has a water slot which is sealed by a sealing pad and a cover board, while the other side of the casing has the mounting slot of an electric heating body in the water slot; moreover, the mounting slot is internally provided with an electric heating body and is also sealed by a cover board; besides, the casing has an interface of the in and out water which is connected with the water pipe. The utility model has the advantages of high heat efficiency, low energy consumption, quick hot water producing and convenient mounting as well as promising no water tank for the water heater and greatly shortening the volume.
Description
Technical field
The utility model belongs to the electric calorifie installation technical field.
Background technology
At present, be used to provide the electric heater of family's shower hot water, kitchen hot water or heating hot water mostly to be provided with water storage tank, volume is big, installs inconveniently, and as heating, the thermal efficiency is low with heating wire or electrothermal tube for its heater, and power consumption is big, and hot water produces slow.The patent No. is 00205883 " a kind of heater of electric heater ", though helpful to addressing the above problem, there is the low deficiency of the thermal efficiency equally in its complex structure.
Summary of the invention
Task of the present utility model is the electric heater unit that a kind of thermal efficiency height of design, generation hot water are fast, the domestic, electric water heater overall volume is dwindled.
The utility model is by the following technical solutions: it has a housing of being made by insulating materials, and a side of housing has water flow grooves, and water flow grooves is by sealing gasket and cover plate for sealing.The housing opposite side has the electric heating element mounting groove between water flow grooves, electric heating element is housed in the groove, and the electric heating element mounting groove is also airtight by cover plate.Have the Inlet and outlet water interface that links to each other with water pipe on the housing.
The used electric heating element of the utility model is to be made of two heat conduction aluminium flakes and the semiconductive ceramic heating plate that is sandwiched in therebetween.
Water flow grooves of the present utility model is reciprocal inflection formula, and the some fin that are made as one with housing are arranged in the water flow grooves.
Compare with the electric heater unit of existing pot-type boiler, the utility model heats water by the special-shaped housing that is cast into by high temperature resistant, ageing-resistant insulating materials, and is big with the contact area of water, and current are long through the time of housing, thermal efficiency height, it is low to consume energy, and it is fast to produce hot water, and water heater need not be provided with water storage tank, volume dwindles greatly, easy for installation, and simple in structure, safe and reliable.

Fig. 1 partly cuts open figure for front of the present utility model;
Fig. 2 partly cuts open figure for the back side of the present utility model;
Fig. 3 is the figure that laterally partly cuts open of the present utility model;
Fig. 4 laterally partly cuts open figure for the used electric heating element of the utility model.
The specific embodiment
In the embodiment that accompanying drawing provides, main casing 1 of the present utility model is formed by nylon material die casting, one side of housing 1 has the water flow grooves 2 of reciprocal inflection formula, the some little heat conducting and radiating sheet 3 that is made as one with housing 1 is arranged in the water flow grooves 2, and water flow grooves 2 is by sealing by seal gasket 9 and the fastening cover plate 4 of stainless steel elasticity that is bolted on the housing 1.The opposite side of housing 1 has electric heating element mounting groove 62 of water flow grooves, and plug-in mounting is equipped with electric heating element 8 in the groove, and encapsulates with insulating cement, and this electric heating element 8 is to be made of two heat conduction aluminium flakes 10 and clip semiconductive ceramic heating plate 11 therebetween.Electric heating element mounting groove 6 is also airtight by the rubber cover plate 7 that is fixed on by screw on the housing 1.The two ends of water flow grooves 2 have the Inlet and outlet water interface 5 that links to each other with water pipe on the housing 1.
