Description
Technical field
What the present invention relates to is a kind of device of electric heater technical field, specifically is a kind of integrated heat pressing type heater that is used for instant water heater.
Background technology
For the storage water heater, its operation principle is directly to heat electrical bar by electric current, and electric energy is converted into heat energy, and then the water that passes in the storage tank uses for the user, also just because of the particularity of the Direct Contact Heating of its electrical bar and liquid, thereby might make the liquid after the heating charged, to such an extent as to cause the accident of personal injury that generation is arranged frequently.In addition,, as wash one's hands, wash one's face, still need whole water tank water heating for the situation of some a small amount of waters, even and after each " normally " use, hot water " residue " all will be arranged in the water tank, it has caused waste of electric energy in essence.Therefore, immediately heating water heater is that quick formula water heater just arises at the historic moment, and as its name suggests, this kind water heater can be heated to uniform temperature with water fast.Compared to the storage water heater, this kind water heater is detained less scaling because of not having a large amount of current.Conventional immediately heating water heater normally forms by folding that water back is unrolled, not only difficulty of processing is big for it, and since the immerging metal tube heater expanded by heating, the cooling after-contraction, to such an extent as to come off from the tube sheet pad so repeatedly, even leaking appears in the damage heating tube.
The heater section of immediately heating water heater on the market just at present is to adopt metal material such as electrical heating fiber tube to be used for flowing water flow in the heating tube as the heating original paper mostly, thereby reach cold water is heated.As everyone knows, general metal all has very strong electric conductivity, although most water heater manufacturer has done very big effort for the electric leakage aspect that prevents heater.Want to avoid fully the heater electric leakage, only depend on the interpolation insulating tape not guarantee fully.It obtains good insulation performance performance also to have a lot of products to use non-metallic pipes, but since generally problem such as the very poor and non-refractory of nonmetallic materials thermal conductivity influence life-span of heater.To the heater that some purchases utilize nonmetallic materials to make, the time that the required time ratio of the hot water of getting generally adopts the metal heater water heater to need is more longer.Thereby how to take rational heater configuration and more suitably heating element heater guarantee the insulating properties and the corrosion resistance of device and improve the technical bottleneck problem that problems such as the thermal efficiency have become immediately heating water heater.
The cermet heating plate promptly is the MCH that often says; abbreviation for Metal Ceramics Heater; it is that tungsten or molybdenum manganese slurry are stenciled on ceramic curtain coating base substrate; build up through hot pressing; then under 1600 ℃ of nitrogen atmosphere protections; pottery and the ceramic heating element that forms of metal co-sintered, metal forming are sandwiched between two potteries and carry insulation characterisitic.Compare with general heater, MCH has universality and higher safety coefficient.
Find through retrieval the prior art document, Chinese patent application number is: 200610115866.2, denomination of invention is: instant heating type MCH alumina ceramic electric water heater, MCH aluminium oxide ceramics heater is installed in this invention sealing on the little water drum body base plate that has Inlet and outlet water to take over, installing hole can adopt the high-temperature heat-resistance silica gel sealing or be fixed in the metal seal casing with direct insertion, and heating element heater is directly inserted in the water.Though but this patent has the characteristics of heating element heater quick heating, because the heating original paper directly inserts in the water, can cause heating inhomogeneous, long-term use can make that fluid sealant is aging to leak, and potential safety hazard is arranged.
Chinese patent application number: 200810068378.X, denomination of invention is: liquid heater and manufacture craft thereof, this invention inserts and puts conduction between two adjacent water pipes heating element heater and insulating paper weld with connecting plate after the fastening assembling of body mutually, make water pipe and heating element heater fit tightly.This form also is the basic structure of present various immediately heating water heaters.This structure exists thermal contact resistance big, and properties of product directly depend on workman's skills involved in the labour, and the pipe fitting welding is complicated, and the easy generation of insulating barrier is broken or scorification causes the water pipe electric leakage, and potential safety hazard is arranged.
Chinese patent application number: 200710171763.2, denomination of invention is: a kind of rapid water heater, the current guiding device of flat pattern structure of container is adopted in this invention, inside is provided with the resistance plate washer, form the crooked back and forth passage of sealing, establish the electric heating sheets device between two adjacent heat conduction guiding devices.The basic heating arrangement of this invention also is a heating pipe clamp electric heating sheets, electric heating sheets insulating paper wrap insulate.The passage processing difficulties that this device is crooked back and forth, and bending channel is difficult to sealing.
