Description
Technical field
The utility model relates to a kind of water dispenser heating tube, especially a kind of quartz heating-pipe.
Background technology
In existing water dispenser heating tube, for instant heating type drinking machine, adopting with the quartz usually is the electrothermal film heating pipe of base material, i.e. heating tube.
Existing heating tube comprises plated film district, electrode district, inwall, outer wall.Basically the plated film district is all at the heating tube outer wall, and electrode district is positioned in the plated film district, need the water of heating to contact with the inwall of heating tube, and inwall is the sliding arc surface of non-ordinary light.
Working condition is given an example: heating tube is vertically installed, and the bottom of heating tube is a water inlet, and top is delivery port, and the heating tube water inlet is communicated with storage tank.After the heating tube energising, the heating of outer wall coatings conducts heat to the interior water of pipe by tube wall then, flows out the delivery port of heating tube until boiling.
Superheated liquid: the temperature that is meant liquid surpasses its boiling temperature and not have the liquid of boiling, can cause the liquid bumping if add the porous mass or the metal that can cause liquid boiling this moment, and is too much if fluid temperature exceeds its boiling temperature, may cause exploding.
The formation reason of superheated liquid: during liquid boiling, liquid internal has a large amount of bubbles to form, and the vapour-liquid interface is increased greatly, so whole liquid is acutely vaporized; In the ordinary course of things, have air in the liquid; The bubble that forms with these existing air bubbles work nuclears has enough big radius.Approach the situation that interface is the plane, have only vapour pressure in the bubble to equal the pressure of liquid, promptly seethe with excitement.If there is not existing air bubble to examine in the liquid, tension force is arranged and the radius that forms is very little.When the temperature that reaches normal boiling point, promptly saturated vapor pressure P equals the pressure p of liquid, and mechanical equilibrium condition requires the pressure of the interior steam pressure of bubble greater than liquid, and phase quilirbium condition has the pressure of the interior steam pressure of requirement bubble less than liquid.Therefore in the temperature of normal boiling point, can not satisfy mechanical equilibrium condition and phase quilirbium condition simultaneously.The temperature of removing on-liquid is higher than normal boiling point, makes corresponding saturated vapor pressure greater than liquid pressure.So, formed superheated liquid.
Described heating tube and storage tank are the linker structure, because the clean smooth inwall of heating tube is unfavorable for absorbed air, therefore the water in the heating tube is difficult to produce micro-bubble when reaching the normal boiling point of water, has only the heating of continuation, in the time of just making in the minute bubbles pressure of water vapour reach bubble to have required pressure, minute bubbles just may produce, and this moment, the temperature of water was higher than normal boiling point, formed superheated water.
Water under this state is extremely unsettled, if heating tube runs into vibrations, or the Shuitu in the pipe is so mixed foreign material, water inside has produced disturbance, will produce bubble, and bubble is heated the moment change greatly, when big number of bubbles is too much, may cause flowed in the liquid short time is hindered, and is similar to line clogging, and this phenomenon is called gas embolism.If this moment, the water of gas embolism bottom seethed with excitement, the force of explosion that boiling produces is owing to be subjected to the effect of upper gas embolism, can put on the tube wall of heating tube, if it is too violent to seethe with excitement, will produce strong wallop to tube wall, can cause the quartz heating-pipe tube wall to break below the extreme case, be similar to blast.Further, water is heated to above the normal boiling point temperature, has also wasted electric energy, and energy-saving effect is poor.
Summary of the invention
Exist the potential safety hazard of booster, the deficiency of energy-saving effect difference, the utility model to provide a kind of energy-saving safe of booster, good energy-conserving effect of can effectively avoiding to scratch the type heating tube when overcoming existing heating tube ebuillition of heated.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of energy-saving safe scratches the type heating tube, comprises inner and outer wall, and the plated film district is positioned at outer wall, and electrode district is positioned at the plated film district, and described inwall is the water stream channel that water that supply and demand will be heated passes through, described inner wall surface be scrape flower-shaped.
Further, the inwall of described heating tube is provided with and scrapes flower-shaped line.
The flower-shaped line of scraping here is not limited to any form, and certainly, inwall also not necessarily is the lines of rule, just in the actual course of processing, can adopt the lines shape of rule usually.
Technical conceive of the present utility model is: the inwall of described heating tube is the surface that scratches, and scratching can be multiple pattern.After described heating tube energising heating, the heat energy that described plated film district produces is transmitted to described inwall from described outer wall, and be transmitted to the water of required heating, because described inner wall surface is to scrape flower-shaped non-smooth surface, scrape the easy absorbed air of flower-shaped non-smooth surface, therefore described inner wall surface just very easily produces minute bubbles, constantly the minute bubbles that produce move up, to water surface boiling, just because of there have been these minute bubbles could guarantee that the water in the described electrothermal film heating pipe just seethes with excitement when reaching normal boiling point, and the boiling position is avoided producing gas embolism, thereby is effectively avoided booster in the first half of heating tube.
Can find that by test the inwall of described electrothermal film heating pipe adopts and scrapes flower-shaped non-smooth surface, in a single day the water of required heating reach normal boiling point and can seethe with excitement, and booster can effectively be avoided all in the first half of heating tube in the boiling position.
The beneficial effects of the utility model mainly show: 1, can effectively avoid the ebuillition of heated booster; 2, good energy-conserving effect.
