Abstract

The utility model discloses an electric-heating instantaneous steam generator comprising an electric heating pipe and a steam conduit. The steam conduit is a spiral shape body made of metal thin wall pipe winded by fixture and the two ends are respectively used as a first exit and entrance and a second exit and entrance. The electric heating pipe is passed through the inner hole formed in the spiral shape body and coordinated with the spiral shape steam conduit. The electric heating pipe and the steam conduit after coordination are located and die-cast into an aluminum heat conductor by an aluminum die casting die. The electric heating pipe is common electrically heated wire which is winded into a linear spring shape and put into an iron pipe; quartz sand is added to make the electric heating pipe insulated from the iron pipe; and a conductive connecting sheet is welded on either guiding needles. The conductive connecting sheets at two ends are both located outside the two ends of the steam conduit spiral shape body. The coordinated electric heating pipe and the steam conduit are put into the aluminum die casting die. Compound die-casting aluminum and embedded-pressed aluminum are poured between the electric heating pipe and the steam conduit to form the aluminum heat conductor having heat conduction effect. The utility model is small in volume, can continuously spurt steam without water, has simple processing technology, large heat exchange area and high heat conversion efficiency, and increases the spatial length from water inlet to steam outlet.

Description

The Instantaneous electric heating steam generator

Technical field

The utility model relates to the Instantaneous electric heating steam generator who is used for steam cleaner.

Background technology

At present, its electric heating steam generator of commercially available steam cleaner has two kinds, and wherein a kind of is the Instantaneous electric heating steam generator, can add water after the short time of promptly switching on and produce steam at once.Application number is that 97245152 utility model patent " electric heating steam generator automatically " discloses a kind of automatic electric heating steam generator that is applicable to clothes ironing, it includes tank body, electric heater, liquid level electrode, blowoff valve, characteristics are to be set with level control electrode and a following level control electrode on one in jar at the top of tank body, the back with water inlet line of tank base lateral inflow mouth is provided with an automatic loading water pump, also be provided with a blowoff valve in tank base, the outlet of steam is arranged on the top of tank body.Itself and design philosophy of the present invention have very big difference.

Owing to electric heating steam generator project organization reason, often cause heat exchange area little and short to the space length of venthole by water inlet, cause the low little vaporization ability of steam production of heat exchanger effectiveness not enough, water phenomenon in the spray vapour appears when spraying vapour continuously.

Summary of the invention

Technical problem to be solved in the utility model is that a kind of volume is little, thermal conversion efficiency is high, spray vapour continuously is not with water, the simple Instantaneous electric heating steam generator of processing technology and provide at above-mentioned deficiency.Its heat exchange area is big, and increased force will is by the space length of water inlet to venthole.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the Instantaneous electric heating steam generator, comprise electrothermal tube and steam guiding tube, the technical measures of taking comprise: the spiral-shaped body that steam guiding tube is turned to through anchor clamps processing by thin-wall metal pipe, and the two ends of this steam guiding tube has suitable length straightway branch respectively as first gateway and second gateway; Electrothermal tube penetrates the endoporus that the spiral-shaped body of steam guiding tube forms, and with spiral-shaped steam guiding tube matched in clearance; Electrothermal tube through cooperating and steam guiding tube are located die cast in the aluminium die casting have the aluminium heat carrier.

The concrete technical measures of taking also comprise: electrothermal tube is put into iron pipe for the common electrical heated filament is wound in the linear springs shape, and adds quartz sand and insulate with iron pipe, and also draws two and weld conductive connecting piece on the pin respectively and be made.

The aluminium heat carrier is formed by aluminium die casting, and it has heat conduction and fixedly electrothermal tube, wireway effect of perfusion.

Steam guiding tube has the increase heat exchange area, and increases the space length distance of first gateway to second gateway.

Compared with prior art, the spiral-shaped body that the steam guiding tube that the utility model adopts is turned to through anchor clamps processing by thin-wall metal pipe, the two ends of this steam guiding tube has suitable length straightway branch respectively as first gateway and second gateway; Electrothermal tube penetrates the endoporus that the spiral-shaped body of steam guiding tube forms, and with spiral-shaped steam guiding tube matched in clearance; Electrothermal tube through cooperating and steam guiding tube are located die cast in the aluminium die casting have the aluminium heat carrier.Electrothermal tube is put into iron pipe for the common electrical heated filament is wound in the linear springs shape, and adds quartz sand and iron pipe insulation, and also draws two and weld conductive connecting piece on the pin; The spiral-shaped body that steam guiding tube is processed into through anchor clamps by thin-wall metal pipe; The steam guiding tube endoporus center that electrothermal tube is inserted spiral-shaped body, and with spiral-shaped steam guiding tube matched in clearance, the two ends conductive connecting piece of electrothermal tube all is positioned at outside the spiral-shaped body two-port of steam guiding tube; Equipped mutually electrothermal tube and steam guiding tube are put into the aluminium die casting locate, matched moulds die casting aluminium, embedding jewelling are filled between electrothermal tube and the steam guiding tube, form the aluminium heat carrier of the effect with heat conduction; This aluminium heat carrier, electrothermal tube and steam guiding tube three perfusion are fixed into an entity.The utility model volume is little, spray vapour continuously is not with water, processing technology simple; Its heat exchange area is big, thermal conversion efficiency is high, and has strengthened by the space length of water inlet to venthole.
