Description
Technical field
The utility model relates to technical field of water heaters, particularly a kind of medicament adding device for water heater and have the water heater of this medicament adding device.
Background technology
Water heater is a set of closed structure, be made up of inner bag, heating system and accessory system etc., in routine use process, due to the metal ion such as calcium, magnesium, iron containing higher concentration in running water, running water has certain hardness, due to heating and inequality of being heated in water heater liner, water inlet easily forms incrustation scale in inner bag, if form the incrustation scale suspended, the mouth of pipe can be blocked, if be attached on heating tube and can affect product efficiency, even reduce Product Safety, serious jeopardizes user's personal safety.
In order to process dirt, can process at water intake end, as demineralized water or interpolation antisludging agent etc., these modes can stop the generation of incrustation scale in inner bag; Also can process incrustation scale in inner bag, namely the incrustation scale generated in inner bag is processed, more commonly use scale remover, the effect of scale remover is fine, but how to add but is a difficult problem, water heater of dismantling takes out heating tube and carries out soaking obviously inadvisable, adds online and needs to increase the devices such as pump, drop into comparatively large, not too applicable.
There is in conventional art a kind of technical scheme adopting venturi principle to add antisludging agent, but there is following problem in this scheme:
1. run difficulty, in product actual moving process, although there is special construction balance pipe to keep internal and external pressure balance, but in actual moving process, because the water hammer effect of running water produces larger pressure, inevitably cause antisludging agent bag external and internal pressure poor, cause antisludging agent amount of precipitation suddenly big or suddenly small, affect result of use.
2. service life is short, in actual use, due to the closedown suddenly of water outlet, can cause certain water hammer effect, and the rising that hydraulic pressure can be sudden, inevitably has a small amount of running water and enter antisludging agent bag, dilute the concentration of antisludging agent; In addition, when user does not operate, the water in water pipe can enter antisludging agent bag due to Action of Gravity Field, can dilute inhibitor concentration equally, can affect its service life.
3. can not add other materials, antisludging agent bag is fixing, does not add other materials by this device, as other medicaments such as essence, scale remover, the fruit liquid being squeezed into juice.
