Description
Technical field
The utility model relates to electric heater, particularly a kind of immediate heating type electromagnet water heater of little installation power.Belong to the electric heater technical field.
Background technology
At present, commercially available domestic, electric water heater, most of water-storage electric heater for the electrothermal tube heating, compare with gas heater, solar water heater, it has easy for installation, is not subjected to climatic field ground condition restriction, and price and cost of use are moderate, therefore general also relatively safer advantage becomes the object that more consumer selects.Its weak point is, because the problem of the electrothermal tube efficiency of heating surface and heating surface, heat time heating time is longer, generally can only make water-storage electric heater, because can not plug and play, make troubles to use; Because electrothermal tube directly is inserted in the water, can not realize electricity separation completely in addition, therefore, have the certain quality potential safety hazard; Besides water storage tank take up room bigger, deficiency such as consumed power during insulation.
In recent years, because the development of Power Electronic Technique, the high-frequency electromagnetic eddy-current heating technique is very ripe, adopts this technology to make the electric heater of heating source, compares with the water-storage electric heater of electrothermal tube heating, has tangible technical advantage.Show as and have the higher thermal efficiency, the thermal efficiency can reach more than 85%～90%, and cost of use is saved in therefore more power saving; Heating surface (area) (HS is big, can make the immediate heating type water heater of plug and play, uses and need not wait for, uses more convenient; Realize electricity separation completely, use safer; It is little to take up room, easy for installation etc., therefore, is subjected to attracting attention of more and more consumers.Also there is the immediate heating type water heater patent of many employing high-frequency electromagnetic eddy-current heating techniques to announce in recent years, as application number 01267076 " immediate heating type electromagnet water heater ", application number is 03235419 " an electromagnetic eddy water heater " etc., also has few a few money immediate heating type electromagnet water heater to release on the market.But patent no matter from announcing, still the product of having released on the market is seen, all have the deficiency of two keys, the one, because no water storage tank, employing is hot mode work, and the thermal capacity of whole system is little, the interference that changed by hydraulic pressure, the water yield, make the sometimes hot and sometimes cold instability of water outlet, manual adjustments is also difficult.The 2nd, be hot mode work owing to adopt, for guaranteeing also to export the hot water temperature, the installation electrical power of equipment is bigger, calculate as can be known, even Efficiency Calculation by 95%, use in the northern area of China, for guaranteeing to export the hot water temperature winter, water heater is installed electrical power at least more than 7KW, use in south, for guaranteeing to use winter water heater electrical power to be installed at least more than 5KW, the power of this product of releasing from recent enterprise is generally 5.5KW, 7.5KW, several specifications of 8.5KW, and this point also is described.Because such installation power requirement, with the installation electrical power of existing general dwelling house big gap is arranged, just need special cable laying, specially ammeter more than the 40A be installed for this water heater is installed, even relating to the problems such as transformation of house lead in cable, this is very limited with regard to the popularization that makes this water heater.In fact, because in the most of area of China, must use big installation power just can make leaving water temperature satisfy the time of instructions for use in 1 year, generally can not surpass 1/3rd, just shorter in this time of south, therefore for guaranteeing the water in winter, have to strengthen the water heater installation power, this has not only strengthened the input of equipment, and the efficient when also having reduced equipment work has more stoped the product of this advantage that possesses skills to enter the dwelling house of now general electrical power installation situation.
