技术领域technical field
本发明涉及一种即热式饮水加热技术领域，具体是一种水加热沸点自适应方法。The invention relates to the technical field of instant drinking water heating, in particular to a water heating boiling point adaptive method.
背景技术Background technique
现有市场上即热式饮水加热装置，当水温达到沸点时，水会在加热管内迅速汽化，产生混合水汽从出水口快速喷出，大量的水蒸气无法冷凝而随热水出水口排出，导致水和水蒸汽因内外压强不同而溅出，如果有人在出水口周围，极易烫伤人体，发生安全事故。In the existing instant drinking water heating devices on the market, when the water temperature reaches the boiling point, the water will quickly vaporize in the heating tube, and the mixed water vapor will be sprayed out from the water outlet quickly. A large amount of water vapor cannot be condensed and will be discharged with the hot water outlet, resulting in Water and water vapor splash out due to the difference in internal and external pressure. If someone is around the water outlet, it is very easy to burn the human body and cause a safety accident.
由于不同海拔地区和不同气压条件下，其沸点存在不同。如果预设较低的温度控制点，例如90℃，在低海拔地区水就不能充分沸腾，烧出来的水不是真正的开水；如果预设高于使用地沸点的温度控制点，水温一直达不到这个温度点而一直改变受控单元（即减小水量或加大功率），而喷水汽情况越来越严重，造成严重安全问题，以及最终导致加热体腔体内水量因汽化不断减少引发加热体干烧损坏。Due to different altitudes and different air pressure conditions, its boiling point is different. If a lower temperature control point is preset, such as 90°C, the water cannot boil sufficiently in low altitude areas, and the boiled water is not really boiled water; if the temperature control point is preset higher than the boiling point of the place of use, the water temperature will not reach When this temperature point is reached, the controlled unit is changed (that is, the water volume is reduced or the power is increased), and the situation of spraying water vapor becomes more and more serious, causing serious safety problems, and finally causing the heating body cavity to decrease due to the continuous reduction of water in the heating body cavity. Dry burn damage.
综上所述，需要一种能自动快速、准确判别即热式饮水装置所在地沸点的方法，从而使加热的水温尽可能接近沸点又要避免出现喷水汽的现象。To sum up, there is a need for a method that can automatically, quickly and accurately determine the boiling point of the instant drinking water device, so that the temperature of the heated water can be as close to the boiling point as possible while avoiding the phenomenon of spraying water vapor.
当前的即热式饮水加热装置普遍采用以下方法：The current instantaneous drinking water heating device generally adopts the following methods:
1、采用温度传感器或温控器的加热电器通常是将控制沸点设置为比真正沸点低几度以适应不同环境下不喷水汽，这样水不能真正沸腾，并且只能适用部分中低海拔地区，这种方法采用的比较普遍。1. Heating appliances using temperature sensors or thermostats usually set the control boiling point to a few degrees lower than the real boiling point to adapt to different environments without spraying water vapor, so that the water cannot really boil, and it can only be used in some low-altitude areas , this method is more commonly used.
2、销往不同地区的产品设定不同的沸点控制温度，这种方法在销售地与使用地不同时也不能避免喷水汽现象。2. Set different boiling point control temperatures for products sold in different regions. This method cannot avoid the phenomenon of spraying water vapor when the place of sale is different from the place of use.
3、内设工厂模式，通过特定的操作（如电位器、程序参数等）设定适应当地的沸点温度，这种方法需要售后人员处理，并且设置后如果使用地点发生变化同样不能避免喷水汽现象。3. Built-in factory mode, through specific operations (such as potentiometers, program parameters, etc.) to set the local boiling point temperature, this method needs to be handled by after-sales personnel, and if the location of use changes after setting, it cannot avoid spraying water vapor Phenomenon.
以上的方法或者需要人工干预或者达不到沸点温度，都无法彻底解决在不同海拔地区和不同气压条件下准确判别沸点。The above methods either require manual intervention or fail to reach the boiling point temperature, and cannot completely solve the problem of accurately distinguishing the boiling point under different altitudes and different air pressure conditions.
另外，中国专利CN200510037189公开的“电热水壶水沸腾的判断方法”，公开的是固定加热功率和水量的电热水壶类加热装置的水沸腾的判断方法，并不适用于对流动水即热式饮水加热装置。In addition, the Chinese patent CN200510037189 discloses a method for judging water boiling in electric kettles, which discloses a method for judging water boiling in electric kettle heating devices with fixed heating power and water volume, and is not suitable for heating drinking water with flowing water. device.

具体实施方式detailed description
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能理解为对本发明的限制。Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.
下面参考图1至图2描述根据本发明实施例的一种水加热沸点自适应方法。A water heating boiling point adaptive method according to an embodiment of the present invention will be described below with reference to FIGS. 1 to 2 .
