Description
1. affiliated technical field
The invention belongs to the domestic, electric water heater field, belong to the Protector for electric appliance field again simultaneously, is the novel household electrical equipment of both ingenious being combined as a whole.Title is protected intelligent all, automatic reclosing, multipurpose continuous-flow type (or claiming Instant heating type) electric heater (following style of writing is called for short the continuous-flow type electric heater).
Hot water is indispensable in family life, no matter does washing, has a bath, steeps foot, washes brace ... Deng all needing it.The supply life is referred to as pot-type boiler with the device of hot water, occupies important position in modern household electrical equipment.
Abroad, the history of the existing many decades of pot-type boiler is used the most general type at present, if by pyrotoxin fork-like farm tool used in ancient China branch: electric heater, gas heater, gas water heater and solar water heater four big classes are arranged.The present invention only relates to the electric heater technology.
Electric heater, the heat energy that is produced when promptly utilizing all kinds of heatings to switch on is heated to cold water temperature required for the household electrical appliance that use.It has diversified pattern, also can adopt diverse ways that it is classified.What often adopt is to divide by the heated mode of cold water: continuous-flow type and storage water heater two big classes are arranged.
(1). continuous-flow type: continuous-flow type claims Instant heating type again, and it is to make cold water flow through the heating of heating power and heated.Heating is rapidly its most outstanding characteristic, generally connects power supply, open from the beginning water valve after, only need just have tens seconds sufficient hot water, flow out endlessly.Therefore, be suitable for most shower, washroom, wash usefulness such as brace and bubble foot.This kind electric heater does not need water tank to store cold water, thereby volume is little, simple installation, and the thermal efficiency is high.
(2). storage water heater: storage water heater is that to utilize heating that the cold water in the water storage tank is heated to temperature required for using.Generally all be that cold water is flowed into by water tank bottom successively, rise, in water tank,, make temperature be tending towards even by the gravity circulation through the heating heat temperature raising.When the water of water tank upper has reached suitable temperature, just can draw use by the delivery port on top.This class electric heater is looked its volume, and decision need preheat the length of time, is used in that shower is minimum will to be preheated 10 minutes and go up, and because of the water tank volume is bigger, area of dissipation is big, and the thermal efficiency is lower, and installing space is bigger, and expense is higher.
