Abstract
The utility model relates to a rapid electric water heater, comprising with a housing, a heating element, a water supply connector and an outlet connector. The housing comprises an upper shell body and a lower shell body, the outside surfaces of them have at least one heating element, the heating medium is cast with the upper shell body, the heating element and the heating medium are covered by the upper shell body and the lower shell body, the inner side has a unblock water socket, the water supply connector and the outlet connector are cast with the lower shell body, and the upper shell body and the lower shell body are locking fixed and airproofed by liquid. Adopting this structure, the heating element is separated with water, and the heating medium and heating element are also isolated with the upper shell body and the lower shell body to prevent creepage. The heating element and the heating medium are cast with the upper shell body and the lower shell body, thus increasing the heat transfer area. The rapid electric water heater has a larger heating area and higher thermal efficiency; effectively prevents the hidden trouble by creepage and is on the safe side.
Description
Technical field
The utility model belongs to the electric-heating technology field, especially a kind of quick-heating type electric water heater.
Background technology
Present prior art, the electric heating element of quick-heating type electric water heater mostly is tube heater greatly or claims electric heating tube, is heating partly to be put into water heat, and surface and water by heating tube carry out heat exchange, thus the heating of realization water.The weak point that this electric heater exists is that heat exchange area is little because of electric leakage brings poor safety performance, and causes the thermal efficiency low.Though some electric heater has installed earth leakage protective device additional; but mostly be the protection of passive type greatly; promptly after leaking electricity; to just can make electric heater outage, its reliability depend on factors such as the insulating properties of performance, quality and electric heating tube of electrical equipment composition element itself and product quality fully according to electric leakage signal.
Summary of the invention
The purpose of this utility model is: a kind of quick-heating type electric water heater is provided, and not only heating surface (area) (HS is big for it, thermal efficiency height, and can prevent the potential safety hazard brought because of electric leakage effectively, safe and reliable.
The utility model is achieved in that a kind of quick-heating type electric water heater comprises housing, heater element, water supply connector, water out adapter, its special character is: described housing comprises upper shell, lower house, have at least heater element, heat medium and a upper shell to be cast into one on the outer surface of upper and lower casing, heater element, heat medium are coated by upper and lower casing, the water passing groove that inner surface has head and the tail to communicate, by piston ring land groove is separated, the water passing groove mirror image symmetry of upper and lower casing, water supply connector, water out adapter and lower house also are cast into one; The upper and lower casing liquid sealing together that is fastened, the piston ring land liquid sealing of the piston ring land of upper shell and lower house.
Described quick-heating type electric water heater, its special character is: seal groove is arranged around the upper and lower casing inner surface, and upper and lower casing is by the sealing ring liquid sealing.
Described quick-heating type electric water heater, its special character is: the screw that connects wall thickness and pass seal groove is arranged around the upper and lower casing, and upper and lower shell body and function Bolt Connection is fixed.
Described quick-heating type electric water heater, its special character is: described groove is an arc or square.
Described quick-heating type electric water heater, its special character is: two or three heater elements are arranged on the outer surface of upper and lower casing.
The utility model quick-heating type electric water heater, housing comprises upper shell, lower house, have at least heater element, heat medium and a upper shell to be cast into one on the outer surface of upper and lower casing, the water passing groove that inner surface has head and the tail to communicate, by piston ring land groove is separated, the water passing groove mirror image symmetry of upper and lower casing, water supply connector, water out adapter and lower house also are cast into one; The upper and lower casing liquid sealing together that is fastened, the piston ring land liquid sealing of the piston ring land of upper shell and lower house.Owing to adopt such structure, heater element and water are isolated, and logical heat medium of heater element and upper and lower casing isolation, prevent electric leakage; Heater element, heat medium and upper and lower casing are cast into one, the corresponding heat transfer area that increased.Not only heating surface (area) (HS is big for it, thermal efficiency height, and can prevent the potential safety hazard brought because of electric leakage effectively, safe and reliable.
