Referring to fig. 1-2, the electric water heater with the soft water purification pretreatment integrated module comprises an electric water heater main body 20 (a shell, an inner container, a heating pipe 21, a water inlet pipe 22, a water outlet pipe 23 and a controller) and further comprises a soft water purifier 10 connected with the water inlet pipe in a preposed manner, wherein the soft water purifier comprises a coarse filter 1, a first pressure pump 2 and an RO membrane filter 4 which are sequentially connected, and the coarse filter is used for primarily filtering solid impurities in water; the RO membrane filter 4 comprises a filtering shell, an RO membrane filtering cylinder 6, an installation spring 5 and a waste water collector 9, wherein a sealing ring 7 is arranged between the outlet end of the RO membrane filtering cylinder and the outlet of the filtering shell, and the installation spring is arranged at the inlet end of the RO membrane filtering cylinder.
The soft water purifier is arranged in a preposed filtering box body (see a dotted line rectangular frame in figure 1), wherein the RO membrane filter cartridge 6 comprises a cylinder body 62, a front end cover 61, a rear end cover and an RO membrane 63, the cylinder body is opened at one end connected with the front end cover, the RO membrane is covered on the cylinder body wall, a plurality of through holes are arranged on the cylinder body wall, the front end cover is provided with an annular groove 64, and the sealing ring 7 is arranged in the annular groove.
The mounting spring 5 is a tower spring.
The filter housing comprises a front shell 42 and a rear shell 41, and the front shell and the rear shell are detachably connected in a sealing mode.
The soft water purifier is provided with a pair of RO membrane filters connected in parallel, and a first switch 3 is provided at the front side of each RO membrane filter.
Still rinse branch road 30 including the RO membrane, RO membrane washs branch road one end and connects inlet tube 22, the front side of soft water purifier 10 is connected to the other end, the RO membrane washs and sets up second switch 31 on the branch road, when needs wash the RO membrane, heating tube 21 stops the heating, the water heater mixes tap and closes and makes into, the outlet pipe does not have rivers to pass through, first force (forcing) pump 2 stops, first switch 3 closes, second switch 31 opens, at this moment, the running water passes through second switch 31, reverse entering RO membrane filters a section of thick bamboo 6, strain to the RO membrane and carry out the backwash, it washes waste water by waste water collector 9 and discharge. In order to enhance the cleaning effect, a second pressurizing pump 31 may be provided in the RO membrane cleaning branch.
The first switch and the second switch can adopt solenoid valves.
A single first booster pump may be used, either installed between the pre-filter and the booster pump, or installed before the pre-filter and the reverse osmosis filter; it can also adopt a design that a double pressure pump is connected with a hot water inlet pipe and a pre-filter, and the other is connected with the pre-filter and a reverse osmosis filter.
The embodiment is a water storage type water heater, and can replace a heating module to become an instant heating type water heater. However, the instantaneous water heater has higher requirements on water outlet speed and heating power, and increasing the filtering speed at the water inlet easily causes the blockage of a coarse filter and a reverse osmosis filter, and increases the cost.
This design also can only adopt single reverse osmosis filter to establish ties in the circuit, but has set up two reverse osmosis filter that connect in parallel in this embodiment, more convenience of customers changes.
In order to facilitate the user to clear the replacement time, a detector for detecting the hardness of the water body is arranged in the shell of the water heater.
When the reverse osmosis filter is not required to be replaced, the front filter box body can protect the electromagnetic valve, the pressure pump and the like from electric leakage caused by wading.
The utility model discloses reverse osmosis unit is different in chooseing for use of well reverse osmosis part and ordinary water purifier, and ordinary water purifier has the requirement to microorganism quantity, water colourity etc. because of the requirement that the human body drunk, nevertheless allows the water to have certain hardness, and the reverse osmosis design that uses in the water heater only has higher standard to the reduction of water hardness, and other aspects are generally not considered. The water volume to be treated in the water heater is higher than that in the drinking water purification treatment, so a waste water collector is arranged to discharge high-salinity waste water after the water body treatment.
When the water heater operates, the electromagnetic valve is opened, the water enters the pressurizing pump through the water inlet pipeline for pressurization, the water pressurization is accelerated to carry out primary filtration on solid impurities in water through the coarse filter, and the ionic impurities are filtered through the reverse osmosis filter, so that the water can enter the heating module. The high salinity wastewater is discharged through a wastewater collector.
The water body with reduced speed and hardness after passing through the reverse osmosis filter has reduced scale generation capacity, and is stored and heated after entering the inner container of the water heater, the scale generated in the process is reduced, and the service life of the water heater can be prolonged.
When the water heater is used, the low-hardness hot water flows out and is mixed with untreated cold water in the water mixing valve to be discharged. The hardness of the water in the water outlet pipeline is reduced compared with that of water in the water inlet pipeline, the scale generation rate is reduced, and the service life of the pipeline is prolonged.
After the anti-seepage device is used for multiple times, the filtering capacity of the anti-seepage filter is reduced, the detector detects that the conductivity in the water storage tank is increased, and after the conductivity exceeds the early warning value, an electric signal is sent to enable the early warning lamp to be turned on, so that a user is prompted to replace the anti-seepage filter. When the reverse osmosis filter is replaced, the switch of the pipeline corresponding to the currently used reverse osmosis filter is closed, and the reverse osmosis filter can be taken down for cleaning or replacement. And simultaneously, the switch of the reverse osmosis filter of the other pipeline corresponding to the pipeline is turned on, so that the water heater can be recovered to be used.
While embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents, and all changes that can be made without inventive step are intended to be embraced therein.
