Problems solved by technology

The above design requirements make it very difficult to place the location and space of the waterway switcher on the medium and small models, and it is even more difficult to install the waterway switcher involved in multiple pipelines in an easy-to-operate position
The above-mentioned defects and deficiencies make it more difficult to install and install a water circuit switcher for filtering and backwash switching in the already extremely complicated water purifier, which directly affects the popularization of this technology

Embodiment 1

[0027] Example 1. An electronically controlled recoil switching method for the filter gallbladder waterway of a water purifier. The machine base is provided with inlet and outlet water pipelines 3 and 4; multiple filter gallbladders 1 are sequentially connected in series to form a filter channel, and the first and rear ends 1a and 1b of the filter channel The inlet and outlet pipelines 3 and 4 are respectively connected, and the filter galls 1 or some of the filter galls connected in series are the recoil filter galls that need to be washed in reverse, or all of them are the filter galls to be recoil that need to be washed in reverse; The electric control valve is composed of sealing and electromagnetic parts connected with the upper and lower valve bodies at the inlet and outlet ends, and is controlled by an electric control device (not shown); multiple electric control valves corresponding to the number of filters to be recoiled The water inlet ends of some of the electric c...

Embodiment 2

[0043] Example 2. On the basis of Embodiment 1, an electric control valve 29 for passing water controlled by an electric control device is additionally provided. The water inlet and outlet ports 29a, 29b of the water passing electric control valve 29 are connected in series between the end of the filter channel and the water outlet pipeline 4; When the filter channel is in the water passing mode, the electric control device controls the water passing electric control valve 29 to conduct; when the recoil channel 5 is in the water passing mode, the electric control device controls the water passing electric control valve body 29 to close.

[0044] attached figure 2 Among them, the water inlet end 20a of the water inlet electric control valve 20 is connected to the water inlet pipeline 3 with the water inlet ends 21a, 22a, 23a of the three recoil water inlet electric control valves 21, 22, 23. The respective water outlets 21b, 22b, 23b of the three recoil water inlet electric ...

Embodiment 3

[0051] Example 3. On the basis of embodiment 1, 2, in conjunction with attached image 3 In the structure shown in the figure, the post-filter channel 7 of the concentrated water pipeline 9 with a reverse osmosis membrane filter 15 and a concentrated water flow control device (not shown) is set in addition and connected to the pure water pipe as the water outlet pipeline 4 Road 4a; the filter channel is a pre-filter channel, or a single water filter channel connected to a post-filter channel 7, or connected to another water purification pipeline 4b with a control valve 6 and a post-filter channel 7 to form The double water filter channel, in which:

[0052] For the single water filter channel, refer to the attached water channel for the water channel of the single water filter channel image 3 , the difference is: there is no clean water pipeline 4b with the control valve 6, and the end of the backflush channel (backflush pipeline 5) and the end of the rear filter channel 7 ...

Abstract

The invention relates to the water treatment industry, in particular to deep filtration and purification of drinking water. The invention discloses an electric control backflushing switching method ofa water purifier filter liner waterway and an integrated electric control valve device thereof. Water inlet ends of part of the plurality of electric control valves controlled by the electric controldevice are connected with a water inlet pipeline to form a water inlet electric control valve with a water outlet end connected with the head end of a filtering channel and a group of backflushing water inlet electric control valves, and water outlet ends of the other part of the plurality of electric control valves are communicated through a backflushing pipeline with an external backflushing connector to form a group of water outlet electric control valves; the water inlet ends of the water outlet electric control valves and the water outlet ends of the backflushing water inlet electric control valves are respectively communicated with the water inlet ends and the water outlet ends of the corresponding to-be-backflushed filter liners; the electric control device conducts the water inletelectric control valve and closes the backflushing water inlet electric control valves and the water outlet electric control valves to form a filtering channel; and the electric control device closesthe water inlet electric control valve and conducts one backflushing water inlet electric control valve and one water outlet electric control valve to form a backflushing channel related to the corresponding to-be-backflushed filter liner. The device further comprises an integrated valve body structure provided with an external water inlet connector and the external backflushing connector.

Description

[0001] Title of prior application: Electronically controlled recoil switching method and integrated electronically controlled valve device for water purifier filter gallbladder waterway [0002] Prior application number: 201910245907.7 technical field [0003] The invention relates to the water treatment industry, and specifically relates to the deep filtration and purification of drinking water. Background technique [0004] Chinese patents ZL200910224481.3, ZL200910246024.4, ZL200910224652.2, and ZL200910215159.4 disclose the "full recoil mode" technical solution involving all filter gallbladders in the filter channel of the water purifier. In these "full recoil mode" technical solutions, the core feature is that all the filters in the filter channel are recoil filters, so as to avoid the impurities flushed out by recoil filters located in the front, and to be affected by the latter. The interception of the non-recoil filter gall in the filter channel so that it cannot be...
