Description
Technical field
The present invention relates to a kind of steam generator and steam cleaning appliance that is used for instantaneous generation steam.
?
Background technology
Steam such as steam cleaning appliance or vapour iron class household electrical appliance are widely used.In the prior art,, the steam generator of the instantaneous generation steam of energy is installed all in these electrical equipment in order to make these electrical equipment not need to preheat generation steam in use.Common steam generator has the calandria (calandria inside is embedded with heater strip) of a hollow, and the inner heating chamber that forms of calandria when water flows through heating chamber, is promptly become steam by instantaneous thermal conversion.
Above-mentioned household electrical appliance are because power is limited and the instantaneous quantity of steam of generation that needs is also little, so the heating chamber internal diameter of calandria inside is very little.The heating chamber of this structure is not a distilled water if be used to produce the water of steam, is easy to produce incrustation scale at the chamber of heating chamber wall after then long-term the use.Therefore heating chamber stops up or the cleaning heating chamber in order to reduce, general heating chamber all is to be designed to one along linearly extended yi word pattern heating chamber (the non-heating chamber that repeatedly bends shape), water enters heat tunnel from an end like this, and steam is just exported from the other end under situation about need not turn round.
The steam generator of said structure can produce following problem in use: since heat tunnel be one along linearly extended heat tunnel, when having a down dip on the steam generator or vertically install, water can fall by gravitate when just having entered in the heating chamber straight down, owing to can continue a segment distance when falling, will certainly shorten heating chamber like this to the heating process of water (former), thereby feasible steam of finally going out not exclusively is steam because the chamber wall of water and heating chamber does not connect slightly when falling.In addition, near the part calandria at water inlet place since all the time less than with enter heating chamber in water contact and carry out heat exchange, so this a part of calandria temperature after work a period of time can become very high, if this part can not in time dispel the heat as persistent fever, the electric equipment generation potential safety hazard of this steam generator can be installed to use.

The specific embodiment
Below by the description that accompanying drawing carries out embodiment, it is clear and easier to understand that advantage of the present invention will become.
Steam generator as shown in Figure 1, its main body is the columned calandria 1 of a slender type, the upper end 12 of calandria 1 is equipped with on water supply connector 2, the bottom 13 water out adapter 3 is installed, and 12 support 4 and installing plate 5 is installed also in the upper end in addition, and the location and installation hole is arranged on the installing plate 5.
As shown in Figure 2, calandria 1 is a hollow structure, has internal face 10 and outside wall surface 11, and the internal face 10 of calandria 1 is the truncated cones face, and diameter diminishes to the bottom gradually from the upper end.The internal face 10 of calandria 1 surround one from the upper end 12 heating chambers 14 that extend to bottom 13, heating chamber 14 is a straight line and extends, and promptly is yi word pattern.Be provided with heating spool 15 and heating spool 16 in heating chamber 14 inside, heating spool 15 is conical, heating spool 15 has excircle wall (not indicating among the figure), has the gap between the internal face 10 of this excircle wall and calandria 1, heating spool 15 is divided into two parts up and down with heating chamber 14, and these two parts only can be communicated with by this gap up and down.Heating spool 15 and heating spool 16 can move along the bearing of trend of heating chamber 14.In order to prevent that heating spool 15 blocks this gap, as shown in Figure 3, on heating spool 15, have a little breach 151.In heating chamber 14, also be provided with long spring 17, hairspring 18 and bulky spring 19, between water supply connector 12 and heating spool 16, hairspring 18 is arranged, between heating spool 16 and the heating spool 15 long spring 17 is arranged, between heating spool 15 and the water out adapter 13 bulky spring 19 is arranged all, heating spool 15 and heating spool 16 are installed in the heating chamber 14 by these springs, heating spool 16 is a square, there is chamfering end at heating spool 16, can make the hairspring 18 can free shrink, the effect of heating spool 16 is the moisture stream that will inject, water can be flowed along the internal face 10 of calandria 1, thereby fully be heated.
Like this, no matter the steam generator horizontal positioned is still tilted to place or even vertically placement can both guarantee water after entering heating chamber, with heating chamber sufficiently long contact area is arranged, thereby makes water all change into steam.In addition, said structure also can guarantee near the part calandria at water inlet place all the time with enter heating chamber in water contact and carry out heat exchange, make the use of steam generator more safe and reliable.
Set forth the course of work of this steam generator below: resource of water supply injects water in the cavity in the water supply connectors 2 by water inlet 21, water is through L type waterflood path 24, delivery port 22 on pressure cap 23 sprays to the internal face of heating chamber 14, water flows along the internal face of heating chamber 14, water enters heating chamber 14 through the space of the internal face 10 of heating spool 16 and calandria 1 subsequently, the first half at heating chamber 14 forms steam through preliminary heating rear section, the latter half that steam and the water gap by heating spool 15 and the internal face 10 of calandria 1 enters heating chamber 14, the latter half at heating chamber 14 all is heated into steam, and steam is through 25 ejections of the steam output channel in the water out adapter 3.Water changes in the process of steam at heating chamber 14, when the steam pressure in the latter half is excessive, bulky spring 19 in the heating chamber 14 and long spring 17 will be subjected to steam pressure and be out of shape, heating spool 15 is moved to the upper end 12 of calandria 1 along the bearing of trend of heating chamber 14, at this moment, the gap smaller of heating spool 15 and the internal face 10 of calandria 1 will reduce from the water yield that the first half of heating chamber flow into the latter half like this, along with steam discharges, steam pressure gradually reduces.When steam pressure is too small, heating spool 15 in the heating chamber 14 will move to bottom 13 directions in the effect lower edge of described several springs, and at this moment, heating spool 15 becomes big with the gap of the internal face 10 of calandria 1, the water yield that flows into heating chamber will increase, thereby steam pressure is increased.
Embodiment 2:
As shown in Figure 4, an application example of the steam generator of the said structure of this accompanying drawing displaying.It has a base 100, and having on the base 100 can be along to be cleaned mobile bottom surface.Base 100 tops are provided with a upright cleaning device body, the cleaning device body comprises a housing 200, a water tank 300 is installed on the housing 200, the inside of housing 200 is provided with steam generator 400, the bottom of housing 200 is equipped with steam distributor 500, and this steam distributor 500 is used for the bottom surface of steam distribution to base 100.
As shown in FIG., steam generator 400 is uprightly to be installed in housing 100 inside, itself and horizontal plane approximate vertical.This steam cleaning appliance because the water that steam generator can instantaneously will flow in the heating chamber all changes into steam, therefore can not produce the water droplet phenomenon in the course of the work.
