Description

Main heating element appearance has the electric heater that heater is intake from tank

Technical field

The utility model is related to the electric heaters that main heating element appearance has heater to intake from tank.

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 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 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, 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 heater 5 made of nano rare earth electric-heating thin film of the main heating element 4 and have disengaging water swivel flow lead to Road 6, and the water inlet of water stream channel or tank 2 is provided with magnetic force contact automatic switch or induction type water flow sensing unit It constitutes, nano rare earth electric-heating thin film heater 5 is sintered on 6 outer surface of water stream channel, and when there is water flowing, automatic switch 7 is just Heater 5 made of nano rare earth electric-heating thin film outside water stream channel is connected, water stops flowing and just disconnects；This heating side Formula heats for water proof, i.e., in water stream channel external heat, never generates electric leakage accident, have method on the end-face hole of tank 2 Orchid I 15 or flange II 16 is provided with II 2-3 of outlet pipe and return pipe 2-2 on the flange, and main heating element 4 is just mounted on water outlet Between pipe II 2-3 and return pipe 2-2, the water in main heating element water stream channel, by II 2-3 of outlet pipe from tank into Enter, in main heating element water stream channel, the water after being heated, by return pipe 2-2 using I 2-1 of outlet pipe of tank 2 Outflow.

The magnetic force contact automatic switch 7 is individual components, by non magnetic ontology 7-1, I 7-2 of permanent magnet, permanent magnet II 7-3, microswitch 7-4, movable contact 7-5, stationary contact 7-6, impeller 7-7, spring 7-8 and III 7-9 of permanent magnet are constituted, permanent magnet I 7-2 blocks water inlet and water stream channel by mutually exclusive magnetic force, and when having water flowing, waterpower is moved using I 7-2 of magnet, II 7-3 of permanent magnet makes impeller 7-7 move simultaneously, and setting movable contact and stationary contact are straight by the strength of water in microswitch 7-4 Connecing makes contact closure or disconnection, and is only limited to control main heating element.

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.

Description of the drawings

Fig. 1 to Fig. 2 is that main heating element is integrated as integrated structure chart with magnetic force contact automatic switch；

Fig. 3 is magnetic force contact automatic switch with the master for having the water stream channel of nano rare earth electric-heating thin film heater to be combined Heating element schematic diagram.

Specific implementation mode

In attached drawing, shell 1, tank 2, I 2-1 of outlet pipe of tank, II 2-3 of outlet pipe on flange, flange On return pipe 2-2, secondary heating element 3, main heating element 4, heater 5, water stream channel 6, magnetic force contact automatic switch or Induction type water flow sensing unit 7, cold water or low temperature water inlet line（Or connector）8, the outlet conduit 9 of healed water, connecting terminal 11, connecting tube 13, water 14, the flange I 15 of flat tank, the flange II 16 of circle tank, liquid expansion type temperature regulating switch 17。

Fig. 1 to Fig. 2 be main heating element it is external from tank into electric heater structure chart, the water of main heating element Circulation road 6 enters cold water or water at low temperature from connecting tube 8, after heating, is flowed out from hot water connecting pipe 9 is gone out；It is illustrated as horizontal list Water tank and double water tank, also vertical water tank are within patent application protection.

Operation principle is：Summer or spring and autumn day, natural temperature>It is cold water in tank 2 at 25 DEG C, when with hot water, by After main heating element 4 is to the cool water heating in tank 2, flow directly out for using；Therefore it changes and in the past first heats water Stored again after to 75 DEG C, the used time directly releases from tank, it is ineffective with do not have to, will will be whole with multi-purpose few One case water heating and heat preservation；Need with how much hot water, i.e., how much hot water is heated by primary heater 4, without not heating after improvement.

Fig. 3 is main heating element and magnetic force contact automatic switch is integrated as integrated structure chart, I 7-2 of permanent magnet and When permanent magnet II 7-3 installations, magnetic force direction is on the contrary, the two is mutually exclusive, and when there is water flowing, I 7-2 of promotion permanent magnet is moved, II 7-3 of permanent magnet just moves impeller 7-7, and movable contact 7-5 just shifts one's position, is in contact with another stationary contact, makes circuit It connects；When magnetic force contact automatic switch be individual components be mounted in tank water inlet when, still in order to control heater 5 connect or It disconnects.
