Description

The external electric heater of main heating element

Technical field

The utility model is related to the external electric heaters of main heating element.

Background technology

The whole world defines storage-type electric water heater at present, is that " heating water simultaneously stores water in container, realizes 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 when hot water, heat waste is failed to keep an appointment in 24 hours>40% very Power consumption, meanwhile, 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 cannot 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 still it is " heating water and by water to be defined as storage-type Storage is in a reservoir ", not big change.

Invention content

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 stores in a reservoir " structure type, realize summer, spring, be not added with hot water in autumn container, only store cold water；Late autumn in 1 year And winter, accounting for about 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 Nonmetallic tank lower part, 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, referred to as secondary heating element；Another group of electric heating element, if It sets except tank 2, referred to as main heating element, no matter whenever needs must there is water to flow through main heating part using when 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 electrothermal tube 5 and has the water stream channel 6 for passing in and out water swivel or electrothermal tube 5 by Nano Rare Native electric-heating thin film sintering is constituted on water stream channel outer surface, and the water inlet of water stream channel or tank is provided with magnetic force Contact or induction automatic switch 7；Electrothermal tube 5 passes through founding mode, welding manner or machine except water stream channel 6 Tool mode is securely connected as one, and when there is water flowing, is just connected the electrothermal tube 5 outside water stream channel, and water stops flowing just It disconnects；This mode of heating be water proof heating, never generate electric leakage accident, main heating element by connecting tube lead realization with Tank function connects.

The magnetic force contact or induction automatic switch 7 are to start and cut off the element of circuit, mechanical contact-type It is in water flow channel, stationary contact and movable contact is arranged directly makes contact closure or disconnection by water and magnetic force, and is only limited to Main heating element is controlled, induction is that Hall element is arranged on water stream channel, when having water flowing, generates electromagnetic pulse and drives Motor type relay is attracted or disconnects, and when using a relay, is only limitted to control main heating element；Secondary heating element, it is swollen by liquid Expanding temperature regulating switch controls, and when using two relays, the external main heating element of a control, another is for controlling water storage Secondary heating element in container.

The utility model has the beneficial effects that：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 does not need 24 hours and continuously heats and keep the temperature, spring and autumn in summer to water It is instant-heating；The hot water of 3-6 times of winter exportable water tank capacity is most energy-efficient water heater.
