本实用新型涉及净水机，特别涉及一种温度可调的净水加热系统。The utility model relates to a water purifier, in particular to a temperature-adjustable water purification heating system.
背景技术Background technique
市面上有的净水机设有冷水、温水和热水模式，不同的水温需要将内部的加热模块设定不同的功率。而在热水模式下，仅能设定、取用一种温度的热水使用。特别是即热工况下，需要使用温度较高的热水时，需要对加热模块设定更高的加热功率，或者降低热水的排放量，方可对水加热到更高温度。这些操作方式均不便于用户使用。Some water purifiers on the market are equipped with cold water, warm water and hot water modes. Different water temperatures require different power settings for the internal heating module. In the hot water mode, only one temperature of hot water can be set and used. Especially under instant heating conditions, when hot water with a higher temperature needs to be used, the heating module needs to be set to a higher heating power, or the amount of hot water discharged can be reduced to heat the water to a higher temperature. None of these operating methods are user-friendly.

The purified water enters the heating water channel 300, then flows through the heating element 320 for heating, and then enters the heat preservation water channel 400, flows through the water replenishing valve 410 and the first one-way valve 420, and enters the heat preservation container 430 for storage.
第三控制阀610在温水模式和第一热水温度模式下可以开启，对多余的水通过泄压水路600回流到过滤水路100中，避免加热水路300水压过大。同时还能通过泄压水路600将净化水回流降低过滤水路100中的水浓度。The third control valve 610 can be opened in the warm water mode and the first hot water temperature mode, and the excess water flows back to the filter water path 100 through the pressure relief water path 600 to avoid excessive water pressure in the heating water path 300. At the same time, the purified water can be returned through the pressure relief waterway 600 to reduce the water concentration in the filtering waterway 100 .
只需将发热体320预设两个功率，一个功率用于温水模式，一个功率用于第一热水温度模式，对于保温容器430的补水模式下，发热体320可使用上述两种功率的其中一种即可，利用发热体320对保温容器430中的热水进一步加热得到更高温度的水，能满足多种温度的净化水的使用。第二热水温度模式下还能保证高温热水的排量。发热体320的功率也可以预设多种功率。It is only necessary to preset the heating element 320 with two powers, one for warm water mode and one for the first hot water temperature mode. For the water replenishment mode of the thermal insulation container 430, the heating element 320 can use one of the above two powers. Only one method is sufficient. The heating element 320 is used to further heat the hot water in the heat preservation container 430 to obtain higher temperature water, which can satisfy the use of purified water of various temperatures. The second hot water temperature mode can also ensure the displacement of high-temperature hot water. The power of the heating element 320 can also be preset to multiple powers.
