Family expenses layering heating electric heater
The utility model belongs to domestic, electric water heater.
Known domestic, electric water heater is a storage water heater, and whole box water heating in the water tank is used, and also some electric heater energising insulation in 24 hours except that having a bath, is only washed with part or small part hot water usually, and its remaining hot water is idle to turn cold.
Water temperature, the different water of density present layering when the objective of the invention is to utilize heating cold water, the upper heat and lower cold phenomenon, according to consumption what, carry out upper strata heating or combined heated, upper water is warm earlier, and it is entering under the case inner cold water pushing tow, discharge water tank, finish the hot wash of few consumption.
The family expenses layering heating electric heater that the utility model is related, by shell (1), water tank (4), heat-insulation layer (2) is set between the two, be provided with a cold water inlet pipe (6) in the water tank bottom, a hot outlet pipe (10) that stretches into tank top also is set, water tank of the present utility model (4) is a press-bearing water tank, so that be suitable for water supply pipe hydraulic pressure, being provided with the ring flange (9) of ring flange (7) bottom heating bar (14) at water tank bottom joins, a sealing ring (8) is set therebetween, in order to sealing radiator, heating bar (14) stretches within the water tank, and heating bar of the present utility model (14) has a metal barred body (3), barred body upper end shutoff, barred body bottom have a ring flange (9) and water tank bottom ring flange (7) closely fixing.Be provided with an earthenware (5) in the heating bar barred body (3), its upper end shutoff, on the earthenware inwall, be provided with the epimere PTC semiconductive ceramic heating ring (13) of three sections heating of can switching on respectively, stage casing PTC semiconductive ceramic heating ring (12), hypomere PTC semiconductive ceramic heating ring (11), its public zero line and live wire are drawn heating bar with lead (15) and are inserted control circuit outward.
Advantage of the present invention is to adopt PTC semiconductive ceramic heat generating component as thermal source, utilizes its temperature from limitting characteristic and machinability, and electric heat source is simple in structure, adopt the syllogic heating system, according to the hot water consumption what, select different heat power layering heating, saved the time and saved the energy.
Description of drawings:
Accompanying drawing: family expenses layering heating electric heater structural representation (1) shell (2) heat-insulation layer (3) barred body (4) water tank (5) earthenware (6) water inlet pipe (7) ring flange (8) sealing ring (9) ring flange (10) outlet pipe (11) hypomere PTC semiconductive ceramic heating bar (12) stage casing PTC semiconductive ceramic heating bar (13) epimere PTC semiconductive ceramic heating bar (14) heating bar (15) lead
Water tank of the present utility model is a press-bearing water tank.The heating bar barred body adopts stainless steel, after the PTC semiconductive ceramic sheet that adopts welds in groups with heat-resisting wire, divide circlewise three sections with the temperature resistant encapsulation sticker on the earthenware inwall, the maximum heating power of every section PTC semiconductive ceramic heating ring is 500W, and the curie point of PTC is transferred to about 90 ℃.
