Abstract
The utility model discloses a steam generator for a smoke exhaust ventilator. The steam generator for the smoke exhaust ventilator comprises a shell, a heating component and a heating tube, wherein the heating component and the heating tube are arranged in the shell; the heating tube is provided with a water inlet and a steam outlet; a water flow channel in the heating tube is U-shaped; the water inlet is positioned in the upper end of the steam outlet; and the diameter of a water inlet channel of a water inlet end of the steam generator is smaller than that of the steam outlet. The outer wall of the heating tube is hermetically connected with the shell; and the heating component is hermetically connected with the shell. The steam generator for the smoke exhaust ventilator is mainly used for the field of kitchens and baths.
Description
Technical field
The utility model relates to a kind of steam generator for smoke exhaust ventilator.
Background technology
In recent years the cleaning way of the smoke exhaust ventilator on market, more and more steam that adopts high temperature carries out self-cleaning oil dirt, not only cleaning efficiency is high, and the feature such as noise is little, extensively be subject to consumer's favor, but the problem that the steam generator of existing smoke exhaust ventilator exists is, the steam generator of the smoke exhaust ventilator of existing market has generally adopted through type heat tunnel to heat and produce high-temperature steam the water in passage, owing to being through type, steam generator is in use time, especially starting moment, the water of water inlet has certain pressure, and now heating tube does not also heat up completely, so just, make the not directly exhaust steam outlet under hydraulic pressure of water of vaporization of part, make vaporization not exclusively, produce steam efficiency not high, consume energy higher simultaneously.
Utility model content
The utility model discloses a kind of steam generator for smoke exhaust ventilator, in order to solve the deficiencies in the prior art.
For addressing the above problem, technical solution of the present utility model is:
A kind of steam generator for smoke exhaust ventilator, comprise shell, and be arranged on heat generating components and the heating tube of enclosure, and on heating tube, there are a water inlet and steam (vapor) outlet, water-flowing path in described heating tube be shaped as U-shaped, and water inlet is positioned at the upper end of steam (vapor) outlet, the diameter of the water inlet path of water inlet end is less than the diameter of steam (vapor) outlet.
The outer wall of described heating tube is connected with body seal.
Described heat generating components is connected with body seal.
The beneficial effects of the utility model are: increased water operating path in the enclosure, improve the efficiency of heating surface, and make water in running, produce turnover, anti-sealing is directly directly directly sprayed onto the drawback of steam (vapor) outlet due to Water Pressure from water inlet, solve the incomplete shortcoming of water vapor, also save the energy simultaneously, improved vaporization efficency.
Brief description of the drawings
Accompanying drawing is structural representation of the present utility model.
In figure: 1-shell, 2-heat generating components, 3-water inlet, 4-steam (vapor) outlet, 5-heating tube.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Referring to accompanying drawing, the utility model comprises shell 1, and be arranged on heat generating components 2 and the heating tube 5 of shell 1 inside, and on heating tube 5, there are a water inlet 3 and steam (vapor) outlet 4, water-flowing path in described heating tube 5 be shaped as U-shaped, and water inlet 3 is positioned at the upper end of steam (vapor) outlet 4, the diameter of the water inlet path of water inlet end 3 is less than the diameter of steam (vapor) outlet 4.
The outer wall of described heating tube 5 and shell 1 are tightly connected.
Described heat generating components 2 is tightly connected with shell 1.
In actual applications, heat generating components 2 and heating tube 5 are installed in shell 1 inside, after switching on power, heat generating components 2 generates heat, heating tube 5 is generally transcalent material and makes, outer casing inner wall can be installed one deck heat-barrier material conventionally, to prevent thermal loss, 5 of heating tubes absorb the heat that heat generating components 2 radiates fast, and it is circular or oval that heating tube 5 is generally, be beneficial to water flows unimpeded in heating tube 5, heating tube 5 in the enclosure portion is that U-shaped is arranged, water injects from water inlet 3, the water of initial heating has certain pressure, cross water can conventionally be slowed down by U-shaped, making its water normally be heated pipe 5 heats, heating tube 5 is rapidly heated, water is in flow process, heated pipe 5 becomes water vapour after being rapidly heated, finally discharged by steam (vapor) outlet 4, because water becomes after water vapour, volume meeting rapid expansion, the diameter of the water inlet path of water inlet end 3 is less than the diameter of steam (vapor) outlet 4, make the steam pressure that steam (vapor) outlet 4 is discharged raise simultaneously, to reach the effect of Rapid Cleaning smoke exhaust ventilator, and common water inlet 3 is positioned at the upper end of steam (vapor) outlet 4, can make like this water can be heated in natural flow process, and after shutdown, also not having too much water rests in steam generator, unnecessary water also can play to steam generator the effect of cooling, and start after steam generator in next time, can prevent not water filling time, produce the shortcoming of steam, and heating tube 5 is rapidly heated and plays a role.
Above-mentioned detailed description of the invention is preferred embodiment of the present utility model; can not limit the utility model; other any change that does not deviate from the technical solution of the utility model and make or other equivalent substitute mode, within being included in protection domain of the present utility model.
