This water heater adopts the method of gradual heating in the water storage tank, and adopts the design of the square wave water passage, which can continuously and fully heat the water when the water flows through it. Therefore, the heating efficiency is high and the energy saving effect is good.
2、本热水器采用竖排的散热片,能把电热片所发出的热量迅速的传送到水中,竖排的散热片可以把一股水流分切成十几小股,大大增加了与发热片的接触面积,增加了热量的吸收。2. The water heater adopts vertical fins, which can quickly transfer the heat from the electric heating fins to the water. The vertical fins can divide a stream of water into dozens of small strands, greatly increasing the distance between the heating fins and the heating fins. The contact area increases heat absorption.
3、本热水器采用集热陶瓷发热片,其特点:发热快,能在3秒钟内就达到其热量的顶值300℃。并且集热陶瓷发热片,还有表面散热越快,功率发热越好的的特点,如一额定功率500W的集热陶瓷发热片3秒钟内表面温度就达到了300℃的顶值,如果不降温,300℃后其功率下降为0,经过散热片用水进行冷却把热量传递到水中。如果水温上升到100℃时,其功率只有350W了,也就是说其表面温度发热越快功率越能发挥。当水温升高高一定温度(如50度),集热陶瓷发热片的功率逐渐下降,如果水温低于该温度,则集热陶瓷发热片的功率又逐渐上升,使得水温能保持在某一恒定值。本实用新型正是采用了集热陶瓷发热片这样的独特特性,达到了节能省电的目的。3. This water heater adopts heat-collecting ceramic heating sheet, and its characteristics: heating quickly, can reach the peak value of 300 ℃ in 3 seconds. And the heat-collecting ceramic heating element has the characteristics that the faster the surface heat dissipation, the better the power heating. For example, the surface temperature of a heat-collecting ceramic heating element with a rated power of 500W reaches the peak value of 300°C within 3 seconds. If it does not cool down , After 300°C, its power drops to 0, and the heat is transferred to the water through cooling fins with water. If the water temperature rises to 100°C, its power is only 350W, that is to say, the faster the surface temperature heats up, the more power it can exert. When the water temperature rises to a certain temperature (such as 50 degrees), the power of the heat-collecting ceramic heating sheet will gradually decrease. If the water temperature is lower than this temperature, the power of the heat-collecting ceramic heating sheet will gradually increase, so that the water temperature can be maintained at a certain level. constant value. The utility model just adopts the unique characteristics of the heat-collecting ceramic heating sheet to achieve the purpose of saving energy and electricity.
4.装配简单,无需专线。由于集热陶瓷发热片功率比电阻丝的功率低很多,因此无需采用专线即可正常使用,因此安装方便,另外,由于集热陶瓷发热片具有前述的智能功率控制特性,因此无需配置温控器,接线也简单。4. The assembly is simple and no dedicated line is required. Since the power of the heat-collecting ceramic heating element is much lower than that of the resistance wire, it can be used normally without using a special line, so it is easy to install. In addition, because the heat-collecting ceramic heating element has the aforementioned intelligent power control feature, there is no need to configure a thermostat , wiring is also simple.
另外,集热陶瓷发热片使用寿命长,能够做到50年不更换,由此可以保证本实用新型的节能即热式电热水器使用年限远远超过其他的热水器。In addition, the heat-collecting ceramic heating sheet has a long service life and can be kept for 50 years without replacement, thus ensuring that the service life of the energy-saving instant electric water heater of the utility model is far longer than that of other water heaters.

After 23 minutes and 07 seconds, the water temperature in the water storage tank reaches 50°C. After opening the cold water pipe, start to press out the hot water, and Control the water flow rate at 120 liters per hour. When the hot water comes out to 10 liters, the water temperature of the water storage tank drops to 45°C due to the injection of cold water. Turn off the cold water pipe. After 4 minutes and 38 seconds, the water temperature of the water storage tank reaches 50°C again. Inject cold water pressure hot water again and go out, so repeatedly, when water container reaches 30 liters, turn off power supply, cold water pipe. The test is over. The measured value is: 30 liters of hot water, water temperature 47 ℃, time spent 46 minutes and 14 seconds, power consumption: 1.54KW/hour.

At the end of the test, the measured value: the power is 4500W, the water temperature is 50°C, it takes 18 minutes, and the power consumption is 1.35KW/hour.
测试(三),测试新颖即热式热水器。Test (3), test the novel tankless water heater.
把30升,23℃冷水加热至50℃所需电量。把一个装有电度计量器的220V电源插座准备好,并把冷水管接到新颖即热式热水器冷水进水管上,把一根接有流量计的热水管接到新颖即热式热水器的热水出水管上。通电、通水用流量计调整水流量至120升/小时。接入计量容器中,并计时,18分钟后达到30升,关闭电源。测试结束,测量值:时间18分钟,水温56℃,实际使用功率:2800W,用电量0.84KW/时。Electricity required to heat 30 liters of cold water at 23°C to 50°C. Prepare a 220V power socket equipped with a power meter, and connect the cold water pipe to the cold water inlet pipe of the new instant water heater, and connect a hot water pipe connected to the flow meter to the new instant water heater. Hot water is on the outlet pipe. Power on, water flow meter to adjust the water flow to 120 liters / hour. Insert it into the metering container, and time it, reach 30 liters after 18 minutes, turn off the power. At the end of the test, the measured value: the time is 18 minutes, the water temperature is 56°C, the actual power used is 2800W, and the power consumption is 0.84KW/hour.
通过测试表明:储水式电热水器虽然功率不大,但是由于要用水时,预热时间长,且浪费热水多,所以电能也消耗多。即热式电热水器,使用方便但由于功率大,用电量也相应较大。新颖即热式热水器既使用方便,而电能消耗最少。The test shows that although the power of the water storage electric water heater is not large, it takes a long time to warm up when water is needed and wastes a lot of hot water, so it consumes a lot of electric energy. The instant electric water heater is easy to use, but due to its high power, the power consumption is correspondingly large. The novel instant water heater is convenient to use and consumes the least electric energy.
