The specific embodiment
The description of through accompanying drawing embodiment being carried out below, the advantage of the utility model will become clear and be more prone to and understand.
Steam generator shown in accompanying drawing 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.
Shown in accompanying drawing 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 from the upper end gradually.The internal face 10 of calandria 1 surround one from the upper end 12 extend to bottom 13 heating chamber 14, heating chamber 14 is a straight line and extends, and promptly is in-line.In heating chamber 14 set inside heating spool 15 and heating spool 16 are arranged; Heating spool 15 is conical; Heating spool 15 has excircle wall (not indicating among the figure); Have 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 through this gap up and down.Heating spool 15 can move along the bearing of trend of heating chamber 14 with heating spool 16.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 arranged, heating spool 16 has long spring 17 with heating between the spool 15; Between heating spool 15 and the water out adapter 13 bulky spring 19 is arranged all; Heating spool 15 is installed in the heating chamber 14 through these springs with heating spool 16, and heating spool 16 is a square, in the end of heating spool 16 chamfering is arranged; Can make the hairspring 18 can free shrink; The effect of heating spool 16 is with the moisture stream that injects, and water can be flowed along the internal face 10 of calandria 1, thereby fully be heated.
Water supply connector 2 is similarly hollow structure; The outer end of water supply connector 2 is the pressure cap 23 that uncovered structure, inner end are installed with a hollow; The inside of the inside of pressure cap 23 and water supply connector 2 connects and forms waterflood path 24, and waterflood path 24 has water inlet 21 delivery ports 22, and is as shown in the figure; The uncovered structure of water supply connector 2 outer ends promptly constitutes the water inlet 21 of waterflood path 24, and this water inlet 21 is connected with resource of water supply; Have a sidewall near the internal face 10 of calandria 1 on the pressure cap 23, delivery port 22 is arranged on the sidewall of pressure cap 23, and whole like this waterflood path 24 is L-shaped.Water out adapter 3 is a hollow structure, and inside forms steam output channel 25.Water out adapter 3 is threaded on the bottom 13 of calandria 1.
Like this, no matter the steam generator horizontal positioned is still tilted to place or even vertically placement can both guarantee that water after getting into heating chamber, has sufficiently long contact area with heating chamber, 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 get into 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 passes through water in the cavity in the water inlet 21 injection water supply connectors 2; 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 gets into heating chamber 14 through the space of heating spool 16 and the internal face 10 of calandria 1 subsequently, forms steam in the first half of heating chamber 14 through preliminary heating rear section, and steam and water are through heating spool 15 the latter half with the gap entering heating chamber 14 of the internal face 10 of calandria 1; 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, and when the steam pressure in the latter half was excessive, the bulky spring 19 in the heating chamber 14 will receive steam pressure with long spring 17 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 drawings show.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 set inside of housing 200 has steam generator 400, and the bottom of housing 200 is equipped with steam distributor 500, and this steam distributor 500 is used for the bottom surface with steam distribution to base 100.
Shown in figure, 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.
The foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection domain of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the utility model.
