U-shaped portion can be fast between 0.4R～0.6R apart from the distance at inner bag top with water heating that should the zone in the inner bag.Satisfy and use hot water, the not too large again user's request of water consumption in some needs short time.As brushing teeth, washing one's face after getting up morning.Wash demands such as dish winter.And the water yield of heating just satisfies the water demand amount of user for a small amount of waters such as washing dish, wash one's face and rinse one's mouth.Make energy-conservation and satisfy the balance that reaches best between user's user demand.The curved design of a of U-shaped portion has increased the contact heating surface area of heating tube with the waters, top to greatest extent.In addition, owing to shorten the time of Fast Heating greatly, the surperficial more difficult long-pending scaling of U-shaped portion heating tube can be guaranteed to add significantly decline of thermal effect after long-term the use.Prolong the lifetime of using.
Point for measuring temperature is arranged on apart from the zone between the central point 0.5R～0.9R of U-shaped portion, neither can excessively closely cause the too sensitive frequent starting of thermometric, stop because of distance U-shaped portion.Again can be because of excessively far causing detection sensitivity to descend and uncontrollable water temperature.Control the variation of water temperature in the U-shaped portion heating region more accurately, prevent the water temperature overshoot, satisfy user's instructions for use, make the user more accurate the control of water temperature.
In the above-mentioned preferred version that the utility model provides: described first heating tube 1 also comprises horizontal part c and rake b, and the ratio of the power of the power of described rake b and a of U-shaped portion is between 1: 2 to 1: 3.Because rake b is positioned at the below of a of U-shaped portion, rake can carry out the desire heating to water in advance when heating, waterborne floating after being heated heated by U-shaped portion again, and the time of water Fast Heating has further been shortened in the desire heating of rake b, improves the Fast Heating efficient of water.
In the above-mentioned preferred version that the utility model provides: as shown in Figure 1, described heating tube also comprises second heating tube 2, described second heating tube 2 is located at the below of described first heating tube 1, and described first heating tube 1 and second heating tube 2 distance at interval are between 10 to 15mm.The power of described first heating tube 1 is that the power of 1500W, second heating tube 2 is 1000W, and described first heating tube 1 and second heating tube 2 heat separately under the control of relay or parallel connection is heated simultaneously.Second heating tube, 2, the first heating tube power are set below first heating tube 1 are made as 1500W, second heating tube, 2 power are made as 1000W.Meeting water heater, the distribution of heating power is reached to greatest extent with on the basis of electric standard.By relay control, realization is heated separately and parallel connection is heated simultaneously.When parallel connection is heated simultaneously, 2 heating of second heating tube, waterborne floating again by 1 heating of first heating tube, the water firing rate is fast, significantly improves the efficient of heating.
In the above-mentioned preferred version that the utility model provides: described temperature measuring equipment comprises temperature tube 8, what described temperature tube 8 tilted is installed on the described ring flange 5, as shown in Figure 2, the angle a of described temperature tube 8 and ring flange 5 spends between 65 degree 75, the diameter of section of described temperature tube 8 is that 3mm is to 10mm, length be 200mm to 220mm, the front end of described temperature tube 8 is described point for measuring temperature.
In the above-mentioned preferred version that the utility model provides: described heating tube also comprises the 3rd heating tube 3, described the 3rd heating tube 3 apart from the distance of inner bag 4 bottoms between 0.25R～0.35R.Be mainly used in the water of heating inner bag lower area or carry out the desire heating, to improve the efficiency of heating surface of whole courage water or 2/3 courage water with first heating tube, the second heating tube work of matching.
In the above-mentioned preferred version that the utility model provides: described outlet pipe passes from a of U-shaped portion of described first heating tube 1.The hot water of U-shaped portion heating can be discharged by outlet pipe 7 very first time, is beneficial to the quick use of hot water, avoids overlong time to cause the heat of water to scatter and disappear.And, since the point for measuring temperature of temperature tube 8 be positioned at U-shaped portion near, more accurate near the hot water temperature U-shaped portion control, fast, make hot water temperature that outlet pipe flows out more meet the instructions for use of user's reality, also respond the water temperature of user's conciliation more fast.
In the above-mentioned preferred version that the utility model provides: the angle of rake b in described first heating tube 1 and horizontal part c and a of U-shaped portion is spent between 65 degree 55 respectively.Become the bending setting of angle between the rake b of first heating tube 1 and U-shaped portion and the horizontal part c, effectively prolonged the physical length of heating tube, the heating tube length of run is long, thereby has increased the contact area of heating tube and liquid, and the pyroconductivity of unit are increases; Under the certain situation of rated power, (W/cm2) is less for the thermic load on heating tube surface, has prolonged the service life of heating tube greatly; In addition, because the thermic load on heating tube surface is less, surface temperature is lower, is not easy to form incrustation scale, and the heat of heating tube can be delivered to heated liquid fast.And reduced heating tube and stretch into actual grade in the inner bag, the arm of force reduces, reduces heating tube and occurs from the situation of root fracture.Level, rake and U-shaped portion are positioned at the differing heights of inner bag respectively simultaneously, can improve the width range up and down of heating.
