The utility model discloses water heater rear end water scale filter's theory of operation and process specifically as follows:

the utility model discloses water heater rear end scale filter includes casing, filtering component and lower casing triplex. The filter is connected by connecting the filter assembly with the lower shell and then connecting the upper shell with the lower shell.

The utility model discloses install at the water heater delivery port through water supply connector 110 when water heater rear end water scale filter uses, hot water flows out the back from the delivery port of water heater, through water supply connector 110 in flowing into intake chamber 400, then in filter element filter screen 320's filtration gets into out water cavity 500, flows out through water supply connector 210 again, gets into in the hot-water line in whole room to the confession is used.

Since hot water scale is generally a solidified component formed by mineral substances in water passing through a high temperature after the water is heated. Therefore, the water outlet of the water heater is connected with the water inlet of the internal thread of the upper shell, and the external thread of the water outlet of the lower shell is connected with the water pipe and enters the hot water pipe of the whole house. Therefore, hot water heated by the water heater enters the filter through the water inlet, water scale formed by high heating temperature is intercepted outside the filter element, and the filtered hot water flows out of the water outlet through the filter element. Therefore, the utility model discloses the filter is the pure physics of hot water incrustation scale and filters, and healthy environmental protection is durable lastingly, and it is convenient to clear up, and the installation cost is low, constructs simple and easy hot water incrustation scale filter. Wherein, support 310, filter screen 320 and connector 330 can form integral type stainless steel filter core, and whole welding is firm, and 350 mesh 316 stainless steel filter screens, the hot water incrustation scale that the interception got into the whole room reaches 97%, because filter assembly leads to setting up and does not make this filter capacious, can store too much incrustation scale impurity to a certain extent, need not clear up at any time, reduces the clearance number of times.

To sum up, the beneficial effects that the utility model discloses water heater rear end scale filter can bring include but not limited to following:

the utility model discloses water heater rear end water spot dirt filter is high temperature resistant, and it is convenient to install, and the whole filter core formula structure as an organic whole of inside stainless steel, 350 mesh 316 stainless steel filter screen resistance weld spot welding are on stainless steel support, reliable and stable, durable. The filter element is reversely arranged on the lower shell, the water yield is not influenced, the filter element is not blocked, and the hot water scale entering the whole house is intercepted by 97 percent. The filter has large internal capacity, good sealing effect and simple disassembly and assembly. The hot water incrustation scale of pure physics filters, and the installation cost is low, need not the consumptive material expense, solves the condition that hot water delivery ports such as domestic vegetable washing basin, washbasin, gondola water faucet blockked up completely, solves to use hot water incrustation scale to block up, frequent clearance worries about after.

It should be noted that all of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except for mutually exclusive features and/or steps.

In addition, the above embodiments are exemplary, and those skilled in the art can devise various solutions in light of the disclosure, which are also within the scope of the disclosure and the protection scope of the present invention. It should be understood by those skilled in the art that the present specification and drawings are illustrative only and are not limiting upon the claims.
