A kind of high heat that is used for care product is imitated steam raising plant
Technical field
The present invention relates to a kind of steam raising plant, especially a kind of steam raising plant that is applicable to care products such as Garment Steamer Machine, flatiron, steam cleaner, steam disinfecting apparatus.
Background technology
The operation principle of traditional heating wire is identical with other metal heater elements, all is the electric heating phenomenon after the metal energising.Electric heating just is meant electric current after passing through conductor, and electric current can produce certain heat and be transmitted out by conductor.Heating wire itself is exactly a metallic conductor, promptly can give out heat after energising, heat energy is provided.In order to solve the shortcoming of the easy oxidation of heating wire (particularly under the hot operation state), just need in the heating wire material, add anti-oxidant element, not only aggravated the manufacturing process difficulty, also increased substantially its cost simultaneously.Except easy oxidation, the intensity of heating wire own also is another disadvantage that heating wire itself need overcome with the operating temperature rapid deterioration that raises, solution is that heating wire is put into a metal tube in the industry, and closely is filled with the crystal magnesium oxide of good thermal conductivity and insulating properties in the gap.In sum, the shortcoming of traditional heating wire heating technique is: volume takes up space greatly, and the indirect type efficiency of heating surface repeatedly is low, easy sparking not easy to clean, easily broken, about 1 year of heater strip life-span.
The core heating part of existing steam series products all can be used the heat generating core that heat-generating pipe die casting is made in aluminium alloy, built-in steam generator as the disclosed Garment Steamer Machine of Chinese patent ZL200920160371.0, heat-generating pipe 201 is as in the heater 200, so the heat radiation of heating wire generation then must penetrate the insulating heat-conductive filler, metal outer pipe, the die casting aluminium, the final aqueous water that just can be delivered in the heat pot, heat radiation loss accounts for 40% during this, its efficiency of heating surface is only less than 60%, show that the deficiency on the product is exactly heat time heating time long (more than 2 minutes), at the bottom of the thermal efficiency, the product heat pot life-span short (less than 2 years).
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, by adopting novel heater element, combine equably with the vaporization pipeline, be heated evenly, thereby a kind of high efficiency steam generator that is used for care product is provided, solves the problem of aspects such as convenient cleaning of prior art and maintenance simultaneously.
Realize that technical scheme of the present invention is: a kind of high heat that is used for care product is imitated steam raising plant, it is characterized in that: described steam raising plant comprises heater element, vaporization pipeline at least, described vaporization pipeline is provided with water inlet and venthole, described heater element is a thick-film heating element, and described vaporization pipeline is installed on the thick-film heating element regularly and becomes one.
Described thick-film heating element comprises basalis, insulating barrier, printed resistor layer, protective layer that resistance is identical or close successively, described vaporization pipeline partly or entirely and basalis fit tightly.
Described vaporization pipeline is a metallic conduit.
Described vaporization pipeline is stainless steel tube or aluminium-alloy pipe or zinc pipe or copper pipe.
Described basalis is stainless steel layer or ceramic layer.
Preferably, described vaporization pipeline be shaped as be shaped as several fonts or helical form concentric circles curve.
The present invention adopts heat-generating disc that thick-film heating element makes and the vaporization pipeline that is connected with this heat-generating disc, and the vaporization pipeline is provided with water inlet and venthole, fixedlys connected between vaporization pipeline and the heat-generating disc, and is reliable to guarantee to connect between the two, heating surface is even.From the existing steam series products heat pot life-span of solution is short in essence, the efficiency of heating surface is low, product too heaviness is not easy to drawbacks such as clean and maintenance.Concrete beneficial effect is as follows:
1. the heat-generating disc that adopts the thick-film heating element manufacturing to form, its charged former device are had the protective layer that material constituted that insulation has the good heat conductive performance simultaneously again and are covered, and leakproof is safe and reliable, but have realized that submergence directly heats efficiency of heating surface height.
2. the heat-generating disc that adopts the thick-film heating element manufacturing to form is because of core heating part thickness is no more than 5um, so realizing having advantageous advantage aspect the product small volume and less weight.
3. the heat-generating disc degree of modularity height that adopts the thick-film heating element manufacturing to form is convenient to assembling and later stage clean and maintenance.

The specific embodiment
Below in conjunction with drawings and Examples the specific embodiment of the present invention is described further.
Shown in Fig. 1 to 5, the structure of the thick-film heating element 1 of related employing in the patent of the present invention is divided into: adopt but be not limited to the substrate 11 that stainless steel or ceramic material are made; The insulating barrier 12 that insulating materials constitutes; The printing heating resistor layer 13 that resistance is close or identical; By having the protective layer 14 that material constituted that insulation has simultaneously the good heat conductive performance again.Vaporization pipeline 2 fits tightly with substrate 11, is combined into one with heater element 1.After heater element 1 energising, heating resistor work produces heat, through protective layer 14 with the heat transferred pipeline 2 of vaporizing.
Aqueous water flow in the vaporization pipeline 2 through the water inlet 3 of vaporization pipeline 2, absorb heat that heater element 1 produces and gradually vaporization produce steam, steam constantly absorbs heat and makes vapor (steam) temperature constantly raise in vaporization pipeline 2 inwall flow process, make the liquid in the pipeline gasify rapidly, when steam temperature about about 240 ℃ (a steam series products performance requirement heat pot venthole place temperature is not less than 200 ℃) greatly when venthole 3 is discharged.
The vaporization runner can be " a few font " or " spirality ", corresponding heater element 1 can be done squarely or disc, purpose is in order to increase heating surface area, and feasible being heated evenly, thereby water or liquid vapour mixture can fully be heated to reach the temperature requirement of steam series products to steam performance in vaporization pipeline 2.
Patent structure of the present invention is simple, realizes that technology difficulty is low, and cost is lower, can be widely used in technical fields such as Garment Steamer Machine, flatiron, steam cleaner, moise-heat sterilization.
Thick-film heating element in the present embodiment is to adopt the thick film silk-screen printing technique; on the substrate of stainless steel or pottery, print materials such as dielectric, heating resistor, conductor, glass protection glaze; by the new type heater spare that high temperature sintering forms, core heating work layer thickness has only 5um.Its remarkable advantage is: small volume and less weight, handsome in appearance, but submergence directly heat, efficient is high, special media covers leakproof, steel plate is a carrier, life-span 5-10.In the heating system of the present invention with its applying steam class care product, give full play to the thick-film heating element life-span long, the efficiency of heating surface is high, the high advantages such as clean and maintenance of being convenient to of product reliability, from the existing steam series products heat pot life-span of solution is short in essence, the efficiency of heating surface is low, product too heaviness is not easy to drawbacks such as clean and maintenance.
