An electrodeionization filter includes: a housing having a water inlet and a water outlet; a first electrode installed inside the housing in a spiral shape; a second electrode installed inside the housing in a spiral shape so as to be spaced apart from the first electrode; and an ion exchange module installed between the first electrode and the second electrode for adsorbing or desorbing ionic substances contained in water introduced by an application of electricity. At least one of the first electrode and the second electrode has a structure in which a center portion thereof is denser than a peripheral region thereof. Accordingly, the lifespan of the electrodes of the electrodeionization filter can be increased, and the assembly of the electrodes and related parts can be easily facilitated.

Electrodeionization filter

Disclosed is a water treatment apparatus which can extract clean water by means of the pressure of raw water. The disclosed water treatment apparatus comprises: a filter part which filters raw water; a storage part which stores clean water filtered by passing through at least a part of the filter part, the storage part having a first chamber and a second chamber of which the volume changes according to a change in the volume of the first chamber; an extraction part which is installed so as to provide the filtered clean water to a user; and an air supply part which is installed on a flow path connected to the storage part in order to supply air to either one of the first chamber or the second chamber of the storage part.

Water treatment apparatus

A water treatment apparatus is disclosed. The water treatment apparatus, according to one embodiment of the present invention, may comprise: a filter unit comprising a reverse osmosis filter for supplying purified water filtered from raw water, and residential water which could not be filtered from raw water; a storage unit connected to the filter unit and comprising a storage member in which purified water is stored, then discharged, and a housing within which the storage member is provided, and through which residential water inflows and outflows; and a flow path changing valve connected to the filter unit and the storage unit, and which allows residential water to outflow from the housing as purified water is stored in the storage member, or allows purified water to be discharged from the storage member as residential water inflows into the housing.

Disclosed are a sterilizing structure of a water outlet and a water treatment apparatus including the same. The sterilizing structure of the water outlet according to an embodiment of the present invention may comprise a water outlet for discharging treated water treated in a water treatment device externally, and a sterilizer for sterilizing the water outlet.

Sterilization structure of water outlet and water treatment device containing same

The present invention provides a water treatment device comprising: a filtering unit for filtering raw water; a storing unit comprising a first chamber for storing purified water, which has passed through at least a predetermined number of filters provided in the filtering unit and thus has been filtered, and a second chamber, the volume of which changes according to the volume change of the first chamber; an extraction unit installed to provide the user with the purified water that has been filtered; an sterilizing water supply unit for supplying sterilizing water in order to sterilize/disinfect the storing unit; and a control unit for controlling the driving of the sterilizing water supply unit and the opening/closing of a channel for supplying the sterilizing water.

Water treatment device

Disclosed are a water storage tank bladder, a manufacturing method therefor, the water storage tank including the bladder, and a water treatment apparatus including the water storage tank. According to one embodiment of the present invention, the water storage tank bladder used in the water storage tank to receive and store water and discharge the stored water has a lower side of which the thickness can be thicker than the thickness of the upper side of the bladder and thicker than the thickness of the lateral sides of the bladder.
