Description

Outer plated film or coiling is nonmetallic or the electric heater of metal electric heating silk

Technical field

Main heating element be the utility model is related to by plating Electric radiant Heating Film outside non-metallic pipe or coiling is nonmetallic or metal electric heating silk Electric heater.

Background technology

The whole world defines storage-type electric water heater at present, is that " heating water is simultaneously stored water in container, is realized equipped with control water The fixed utensil of warm device "；Electric heating element i.e. in container（Or electrothermal tube, similarly hereinafter）Be will to the water in water tank, 24 75 DEG C of hour laser heating and holding, using directly being released from container during hot water, when 24 is small, interior heat waste is failed to keep an appointment>40% very Power consumption, meanwhile, its hot water delivery rate is about the 70% of water tank capacity, that is, when water tank capacity is 60L, can only provide about 40L heat Water, it is impossible to meet modern's demand.

Patent application ZL200720061206.0, ZL200820098512.6, are equipped with heating tube in outlet pipe； ZL03220700.X, ZL201020505717.9 realize leveled heating, but it is that " heating water is simultaneously to be at least still defined as storage-type Store water in container, " without big change.

The content of the invention

The utility model is improved existing storage-type electric water heater, and it is that " heating water simultaneously will fundamentally to change water heater Water store in a reservoir " structure type, realize in summer, spring, autumn container and be not added with hot water, only store cold water；Late autumn in 1 year And winter, accounting for annual 1/3 time just needs storage warm water, and the hot water used is directly to be released from main heating element.

The technical measures of the utility model are that have two groups of electric heating elements in the shell of water heater, one group be located at metal or Inside nonmetallic tank, summer or spring and autumn day, when natural temperature is higher, this group of electrothermal tube does not work, only in late autumn Or winter, i.e., only have this group of electrothermal tube of short time just to work in 1 year, be known as time heating element；Another group of electric heating element, if Put outside tank 2, be known as main heating element, no matter whenever need there must be water to flow through main heating part using during hot water Part, at this time main heating element turn on automatically heats the water flowed through, for users to use.

The main heating element 4 is by plating Electric radiant Heating Film or the nonmetallic carbon fibre electrothermal wire of coiling or heating alloy outside non-metallic pipe Heater 5 made of silk is formed with the water stream channel 6 and four-way connection 15 for having disengaging water swivel, and is held in water stream channel or water storage The water inlet of device is provided with magnetic force contact automatic switch or induction type water flow sensing unit 7, and this mode of heating heats for water proof, Realized and tank function connects by four-way connection or connecting tube in water stream channel external heat, main heating element.

Tank 2 is provided with water inlet pipe 2-1, outlet pipe 2-2, and main heating element is just installed on outlet pipe 2-2 outlet portions , the water in its water stream channel, enters, method is the exposed junction in outlet pipe 2-2, has one four to connect from outlet pipe 2-2 First 11, main heating element is just installed on four-way connection, its connection method is four-way connection by 11-1,11-2,11-3,11-4 tetra- A interface composition, 11-1 are communicated with 11-2, and 11-3 is communicated with 11-4, and the interface 11-1 and 11-4 of coaxial line are not communicated with, interface 11- It is a rotatable nut at 1,11-1 is connected with the outlet pipe 2-2 of tank 2, and 11-2 is connected with automatic switch 7,15-3 Be connected with the outlet conduit of the healed water of main heating element, 11-4 with regard to whole water heater hot water outlet.

The magnetic force contact automatic switch 7 is startup and the original paper for cutting off 5 circuit of heater, by non magnetic body 7-1 Permanent magnet 7-2 permanent magnet 7-3, microswitch 7-4, movable contact 7-5, stationary contact 7-6, impeller 7-7, spring 7-8 permanent magnets 7-9 Form, permanent magnet 7-2 blocks water inlet and water stream channel by mutually exclusive magnetic force, and when having water flowing, waterpower makes permanent magnetism Iron 7-2 is moved, while permanent magnet 7-3 moves impeller 7-7, and movable contact 7-5 and stationary contact 7-6 is set in microswitch 7-4 Make contact closure or disconnection by water and magnetic force amount, control main heating element.

The beneficial effects of the utility model are：1. water heater is not heating water and stores water in the component in container, the summer, Cold water is only stored in spring, autumn tank；2. electric heater, it is not necessary to which 24 continuously heat water and keep the temperature, spring and autumn in summer when small It is instant-heating；Winter exportable several times more of hot water compared with the identical water heater of capacity, power, is most energy saving hot water Device.
