Below with reference to Fig. 1-Figure 10, the steam generator 100 according to this utility model embodiment is described.Steam generator 100 is usable in steam generator system, and is applied in household electrical appliance such as vacuum cleaner, Garment Steamer Machine, lampblack absorber, coffee machine, washing machine, air-conditioning or microwave oven etc. with steam generator system, for producing steam.

As shown in Fig. 1-Figure 10, housing 1, heating element heater 3 and at least one gaining structure 4 can be included according to the steam generator 100 of this utility model embodiment.Heating element heater 3 can be located in housing 1, consequently facilitating the water in heated shell 1.The electrical terminal 31 of heating element heater 3 is positioned on the lateral wall of housing 1, in order to switch on power, and facilitates the work of heating element heater 3.

Specifically, as shown in Fig. 1, Fig. 3, Fig. 4-Fig. 5 and Fig. 9, housing 1 includes base 15 and 16 lid.The open-top of base 15, is provided with partition wall 2 in base 15, lid 16 closed base 15 to limit two exocoels being spaced apart from each other 11 and inner cavity chamber 12 with base 15 and partition wall 2.The partition wall 2 such as arranging annular in base 15 goes out exocoel 11 and inner cavity chamber 12 with interval, and makes exocoel 11 around inner cavity chamber 12.Thus be conducive to increasing the volume of base 15 on the one hand by arranging two chambers being spaced apart from each other, the partition wall 2 being arranged in base 15 on the other hand also helps the surface area increased in housing 1, consequently facilitating adhere to more incrustation scale, avoid the damage of the steam generator 100 caused because incrustation scale is too much to a certain extent, extend the service life of steam generator 100.

Communicated with each other by least one connectivity slot 21 between exocoel 11 and inner cavity chamber 12, for instance, communicated with each other by a connectivity slot 21 between exocoel 11 and inner cavity chamber 12, and connectivity slot 21 is located on partition wall 2.Lid 16 has water inlet 13 and steam (vapor) outlet 14.Water inlet 13 connects with exocoel 11 with one of them in steam (vapor) outlet 14, and water inlet 13 connects with inner cavity chamber 12 with another in steam (vapor) outlet 14, that is, when water inlet 13 connects with exocoel 11, steam (vapor) outlet 14 then connects with inner cavity chamber 12, when water inlet 13 connects with inner cavity chamber 12, steam (vapor) outlet 14 then connects with exocoel 11.

Thus, by arranging the inner cavity chamber 12 being spaced apart from each other and exocoel 11 in housing 1, make water inlet 13 connect with exocoel 11 with one of them in steam (vapor) outlet 14 simultaneously, and water inlet 13 connects with inner cavity chamber 12 with another in steam (vapor) outlet 14, in the use procedure of steam generator 100, when steam (vapor) outlet 14 persistently discharges steam, water inlet 13 can be passed through and add water (such as in inner cavity chamber 12 or exocoel 11 easily, when water inlet 13 connects with exocoel 11, when steam (vapor) outlet 14 connects with inner cavity chamber 12, water inlet 13 can be passed through add water in exocoel 11, when water inlet 13 connects with inner cavity chamber 12, when steam (vapor) outlet 14 connects with exocoel 11, water inlet 13 can be passed through add water in inner cavity chamber 12), this avoid boiler type steam generator 100 of the prior art in use add water inconvenience problem, and compared to boiler type steam generator 100, steam generator 100 in this utility model has less volume, when steam generator 100 is arranged in household electrical appliance with steam generator system, be conducive to the miniaturization of household electrical appliance.

Heating element heater 3 is arranged on partition wall 2 so that inner cavity chamber 12 and exocoel 11 to be heated.Such as, heating element heater 3 can be located in partition wall 2, in the internal face of partition wall 2 or outside wall surface so that inner cavity chamber 12 and exocoel 11 are heated.Certainly, this utility model is not limited to this, and heating element heater 3 can also be located at other position and such as be located in inner cavity chamber 12 or exocoel 11.

Alternatively, steam (vapor) outlet 14 connects with inner cavity chamber 12 and is correspondingly arranged with the center of inner cavity chamber 12.Certainly, this utility model is not limited to this, and steam (vapor) outlet 14 also may be provided in other positions of the roof (i.e. lid 16) of the housing 1 corresponding with inner cavity chamber 12, as long as the water vapour being easy in inner cavity chamber 12 is discharged.

Alternatively, partition wall 2 is collinear with the centrage of base 15, say, that the centrage of inner cavity chamber 12 and exocoel 11 is collinear, thus, not only it is easy to water vapour and flows through exocoel 11 swimmingly, but also can so that heating element heater 3 uniformly heats the water vapour in exocoel 11.It is, of course, understood that the centrage of inner cavity chamber 12 and exocoel 11 can not also be collinear.

Steam generator system according to this utility model embodiment, including above-mentioned steam generator 100.

Steam generator system according to this utility model embodiment, can extend the service life of steam generator system.

Household electrical appliance according to this utility model embodiment, including above-mentioned steam generator system.

Household electrical appliance according to this utility model embodiment, by arranging above-mentioned steam generator system, can extend the service life of household electrical appliance.

According to embodiments more of the present utility model, household electrical appliance are vacuum cleaner, Garment Steamer Machine, lampblack absorber, coffee machine, washing machine, air-conditioning or microwave oven.

Although above it has been shown and described that embodiment of the present utility model, it is understandable that, above-described embodiment is illustrative of, it is not intended that to restriction of the present utility model, above-described embodiment can be changed in scope of the present utility model, revises, replace and modification by those of ordinary skill in the art.
