Description
Technical field
The utility model relates to a kind of water dispenser heating tube, especially a kind of electrothermal film heating pipe.
Background technology
In existing water dispenser heating tube, adopting with the quartz usually for instant heating type drinking machine is the electrothermal film heating pipe of base material, i.e. electrothermal film heating pipe.
Existing electrothermal film heating pipe comprises plated film district, electrode district, inwall, outer wall.Basically the plated film district is all at the electrothermal film heating pipe outer wall, and electrode district is positioned in the plated film district, need the water of heating to contact with the inwall of electrothermal film heating pipe, and inwall is the sliding arc surface of non-ordinary light.
Working condition is given an example: electrothermal film heating pipe is vertically installed, and the bottom of electrothermal film heating pipe is a water inlet, and top is delivery port, and the electrothermal film heating pipe water inlet is communicated with storage tank.After the electrothermal film heating pipe energising, the heating of outer wall plated film layer conducts heat to the interior water of pipe by tube wall then, flows out the delivery port of electrothermal film heating pipe 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 electrothermal film heating pipe and storage tank are the linker structure, because the clean smooth inwall of electrothermal film heating pipe is unfavorable for absorbed air, therefore the water in the electrothermal film heating pipe 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 electrothermal film heating pipe 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 quartzy electrothermal film 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
Have the potential safety hazard of booster, the deficiency of energy-saving effect difference when overcoming existing electrothermal film heating pipe ebuillition of heated, the utility model provides a kind of anti-explosion tube-type instant heating type drinking water machine that can effectively avoid booster, good energy-conserving effect.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of anti-explosion tube-type instant heating type drinking water machine comprises electrothermal film heating pipe, and described electrothermal film heating pipe comprises inner and outer wall, the plated film district is positioned at outer wall, 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, and described inwall is provided with explosion-proof interlayer.
Further, described explosion-proof interlayer be radial arrangement or simultaneously radially, axial arranged, described explosion-proof interlayer is provided with water stream channel.
Or: described explosion-proof interlayer is axial arranged.
Further again, described explosion-proof interlayer is the sieve aperture shape.
Further again, for the explosion-proof interlayer of radial arrangement: described inwall is provided with explosion-proof interlayer more than two from top to bottom.
For axial arranged explosion-proof being divided into: described inwall is provided with explosion-proof interlayer more than two.
The form of described explosion-proof interlayer can have multiple, above-mentioned sieve aperture shape just wherein a kind of, for the explosion-proof interlayer of radial arrangement, can also select multiple other forms such as grid type, through hole type; For axial arranged explosion-proof interlayer, can select multiple other forms such as linear pattern, spiral line type, notch cuttype.
The mounting means of described explosion-proof interlayer also can have multiple: for example, the explosion-proof interlayer of radial arrangement can be fixedly mounted on the inwall, and axial arranged explosion-proof interlayer is installed on the mounting bracket, and described mounting bracket is installed on the mount pad at heater two ends.
Technical conceive of the present utility model is: the inwall of described electrothermal film heating pipe is provided with explosion-proof interlayer.After described electrothermal film heating pipe 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 inwall is provided with explosion-proof interlayer, the easy absorbed air of described explosion-proof interlayer, 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 is provided with explosion-proof interlayer, 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.
