Description

FILTER ASSEMBLY AND PURIFIED WATER STORAGE DEVICE INCLUDING SAME

The present invention relates to a filter assembly and a water purification device including the same. More specifically, the present invention relates to a filter assembly having an increased filtration efficiency of a filter and having a bypass path so as to be capable of controlling the removal rate of residual chlorine in tap water, and a water purification device including the same.

Recently, as environmental pollution, especially water pollution, has become a social problem, the use of water purification devices that physically or chemically filter water to remove impurities is increasing.

This type of water purifier is a device that filters out various harmful substances that are harmful to the human body contained in raw water such as tap water or groundwater, and converts them into safe and sanitary drinking water. A typical water purifier is equipped with multiple filters to filter raw water and provide purified water, thereby removing harmful substances contained in the raw water and filtering out floating substances.

These water purifiers may be equipped with various filters to filter raw water, and the filters are generally configured to include various filter media in a housing formed in a hollow cylindrical shape to filter raw water. The filters mainly used include pre-carbon filters, ultrafiltration filters, reverse osmosis filters, sediment filters, and post-carbon filters. Among the various filters, carbon filters are filters for adsorbing small contaminants, residual chlorine, volatile organic compounds, or odor-causing particles. These conventional carbon filters use activated carbon to remove residual chlorine in tap water and improve the taste of drinking water, but they can become vulnerable to bacteria and germ growth by removing residual chlorine. In the past, carbon block filters were mainly used in ice makers and water purifiers for the purpose of improving the taste of ice and water, but in cases where purified water must be stored for a long time, such as in ice makers and water purifier storage devices, bacteria and germ growth may occur, resulting in sanitary and economic losses. In such cases, filters that do not remove chlorine are sometimes used, but there is a problem in that the taste of water and ice deteriorates because residual chlorine is not removed, resulting in user dissatisfaction.

In addition, recently, there has been an increase in consumers who expect the dual effects of water taste and sterilization by controlling the removal rate rather than completely removing residual chlorine. Conventional filters have only one characteristic, such as removing or preserving residual chlorine, and it is difficult to control the removal of residual chlorine.

The filter housing (100) of the above filter unit (10) may be configured to include a head coupling portion that protrudes vertically to form a step structure and is coupled with a filter head (20). The filter housing (100) may be configured as a cylindrical shape with a hollow interior, and may accommodate a filtering member. The head coupling portion may be formed with an inlet for raw water to flow in, a bypass inlet (102) for raw water to flow in controlled by a flow control means included in the filter head (20), and an outlet for discharge of purified water.

Meanwhile, the filter unit (10) may include a first filter bracket (140), as shown in FIGS. 11 and 12. The first filter bracket (140) may be included in the lower portion of the first filter unit (110) and coupled to the filter housing (100). The first filter bracket (140) may include a first raw water pipe insertion portion (143) into which a raw water pipe (101) and a tube are inserted. A raw water pipe (101) into which raw water flows and a tube (170) surrounding the raw water pipe (101) may be inserted into the first raw water pipe insertion portion (143), and the first filter bracket (140) may have a plurality of paths formed therein so that raw water discharged from the raw water pipe (101) through the first raw water pipe insertion portion (143) may be directed to the first filter unit (110).

Here, the first filter bracket (140) can form a flow path that is in fluid communication with the raw water pipe (101). The first filter bracket (140) can be combined with the filter housing (100) to support the first filtering unit (110), and raw water flowing out of the raw water pipe (101) can flow into the first filtering unit (110) through the flow path formed in the first filter bracket (140) to remove residual chlorine.

The first filter bracket (140) may include a stopper (141) that prevents the first filter bracket (140) from sagging. The stopper (141) is formed on the first filter bracket (140) and is combined with the filter housing (100) to support the first filter bracket (140) and prevent sagging.

The stopper (141) may be formed with a plurality of first filtering channels (142) at predetermined intervals through which raw water flowing out of the raw water pipe (101) may be discharged. Raw water discharged from the raw water pipe (100) through the first filtering channels (142) may pass through the plurality of channels formed in the first filter bracket (140) and flow into the first filter unit (110). Raw water passing through the channels formed in the first filter bracket (140) may have residual chlorine removed by the first filter unit (110).

The filter unit (10) includes a second filter unit (120) and can filter raw water and raw water from which residual chlorine has been removed. For example, the second filter unit (120) can be composed of a sediment cartridge, but is not limited thereto.

The filter housing (100) is partitioned vertically by the second filter bracket (150), and the inflow of raw water is controlled by the filter head (20) including the flow control means, so that the amount of raw water flowing to the first filtering unit (110) is controlled, so that the content of residual chlorine can be controlled.

The second filter bracket (150) can form a second bypass path (154). The amount of raw water flowing in through the bypass inlet (102) of the filter unit (10) can be controlled by the flow control means of the filter head (20), so that the raw water can flow into the second bypass path (154), and the amount of raw water passing through the first filter unit (110) can be controlled.

The second filter bracket (150) may be formed with a plurality of second filtration channels (151) through which raw water supplied through the second bypass channel (154) and raw water from which residual chlorine has been removed in the first filter unit (110) may be introduced into the second filtration unit (120). The second filtration channels (151) may be formed so that raw water supplied through the second bypass channel (154) and raw water from which residual chlorine has been removed may be introduced into the second filtration unit (120).

The second filter bracket (150) may include a first fixing part (152) into which the second filtering part (120) is inserted and fixed. The second filtering part (120) may be inserted and fixed into the first fixing part (152), and raw water and raw water from which residual chlorine is removed from the first filtering part (110) may be introduced into the second filtering part (120) through the second filtering path (152) included in the second filter bracket (150) and filtered into purified water.

The scale-inhibiting unit (130) may be included in the upper portion of the second filtering path (152) and the outer surface of the second filtering unit (120). It may be included in the upper portion of the second filtering path (152) included in the second filter bracket (150) to suppress the occurrence of scale in the raw water and the raw water filtered in the first filtering unit (110). For example, the scale-inhibiting unit (130) may be composed of phosphate (PO ₄ ^3- ), but is not limited thereto. When the phosphate is injected at a certain concentration, the pipe is coated to suppress the occurrence of scale.

The second filter unit (120) may include an upper cap (160) through which the raw water pipe (101) is inserted and connected to the outlet. The upper cap (160) may be hot-melt bonded to the second filter bracket (150) and may include a second fixing member (161) into which the second filter unit (120) is inserted and connected.

The amount of raw water flowing into the second bypass passage (154) through the first bypass passage (103) may be controlled, and the amount of raw water passing through the first filter unit (110) may be controlled as the amount of raw water passing through the raw water pipe (101) is controlled, and accordingly, the content of residual chlorine included in purified water filtered and discharged from the filter unit (10) may be controlled.

The upper cap (160) may include a catch (162). One side of a connecting portion that is inserted and connected to the second filter bracket (150) may be formed to protrude outwardly to form a catch (162), and the upper cap insertion portion (153) formed in the second filter bracket may be caught on the catch (162), thereby preventing the upper cap (160) from being excessively inserted into the second filter bracket (150).

The outlet (220) may have an outlet formed on the other side facing the inlet of the inlet (210) and have an outlet path that communicates with the outlet pipe (113) so that purified water may be discharged by passing through the filter body. The lower header (202) may be formed with at least one bypass inflow hole (202a) formed as an inflow path for raw water flowing into the first bypass path (103) around a central hole (203) penetrating the inner side while being coupled to the lower side of the upper header (201).

Here, the flow control means (300) of the filter cartridge header (200) is configured to sequentially penetrate the upper header (201) and the lower header (202) and is formed to be exposed in a lid shape on the upper outer side by manipulating the rotary opening/closing dial (320) to adjust the opening/closing range of the bypass inflow hole (202a), thereby allowing the amount of raw water flowing into the bypass flow pipe (112) to be gradually adjusted. At this time, the bypass flow control means (300) can control the rotation radius of the rotary opening/closing dial (320) to adjust the amount of raw water flowing into one or more bypass inflow holes (202a) formed on the inner side of the lower header (202).

The above-described flow control means (300) may include a flow control housing (310), a rotary opening/closing dial (320), and a housing support spring (330). The upper portion of the flow control housing (310) may penetrate the upper header (201) and the lower portion may be positioned at a point where the bypass inflow hole (202a) of the lower header (202) is formed. In addition, the rotary opening/closing dial (320) may be arranged on the upper side of the upper header (201) and coupled with the upper portion of the flow control housing (310). In addition, the housing support spring (330) may be formed around the outer surface of the flow control housing (310) to perform an additional spring function, thereby enhancing the sealing force of the bypass inflow hole.

The above-described housing (310) for controlling flow rate may be configured to include a communication hole (311) formed on the side to allow raw water to flow in through the inlet portion (210) formed on the upper header (201), a housing blocking member (312) formed on the lower surface to stepwise block the bypass inflow hole (202a) formed on the lower header (202) in response to the rotational motion of the rotary opening/closing dial (320), and a rotational power transmission member (313) formed on the upper end to transmit the rotational motion of the rotary opening/closing dial (320).

The flow control means (300) can control the amount of raw water flowing into one or more bypass inflow holes (202a) formed at the bottom edge of the inner wall of the lower header (202) by controlling the rotation radius of the rotary opening/closing dial (320) described above.

More specifically, the bypass inlet holes (202a) illustrated in the embodiment of the present invention are shown in various cases from stage 0 to stage 7 depending on the number of bypass inlet holes (202a) to be sealed, with a maximum of 8 on one side, but this is not limited to this and may be formed in various numbers as needed.

At this time, the housing (310) for controlling the flow rate may be provided with a housing blocking member (312) capable of sealing a specific range of the inflow holes (202a) among the one or more bypass inflow holes (202a) at a certain portion of the lower surface periphery, and in the embodiment of the present invention, the housing blocking member (312) may seal a different number of bypass inflow holes (202a) for each stage. In addition, as described above, the raw water flowing in through the raw water pipe (101) basically forms a first flow path that sequentially passes through the first filtering unit (110) and the second filtering unit (120), and the raw water flowing in through the second bypass flow path pipe (154) may additionally form a second flow path that directly passes through the second filtering unit (120) without passing through the first filtering unit (110). Therefore, by controlling the amount of raw water flowing into the flow pipe (154) using the flow control means (300), the flow rate ratio between the first flow path and the second flow path can be controlled, thereby controlling the content of residual chlorine.

In addition, the present invention has the effect of facilitating maintenance of the product by enabling the filter cartridge header to be assembled into an upper header and a lower header.

In addition, the present invention has the effect of increasing convenience for users by allowing the amount of raw water flowing into the bypass path to be easily controlled using a rotary opening/closing dial exposed on the upper side of the filter cartridge header.

In addition, the present invention can be implemented in a push-pull manner when configuring an opening/closing dial in a filter cartridge header, and by using various engaging structures inside, the opening/closing dial is prevented from coming off during operation and is prevented from rotating during non-operation, thereby fundamentally preventing malfunctions that may occur during use.

Below, a specific operation example of the filter cartridge header (200) including the aforementioned flow control means (300) is described with reference to the drawings.

As described above, the bypass flow control means (300) can control the amount of raw water flowing into one or more bypass inflow holes (202a) formed at the bottom edge of the inner wall of the lower header (202) by controlling the rotation radius of the rotary opening/closing dial (320).

As shown in Fig. 10, the bypass inlet hole (202a) can have seven openings in one direction. That is, the bypass inlet hole (202a) can be divided into seven stages from stage 0 and can be sealed according to the flowing flow rate, thereby controlling the flow rate.

According to an embodiment of the present invention, an inflow hole blocking member (312) is formed with a predetermined length at a portion facing the bypass inflow hole (202a) at the lower end of the housing (310) for controlling the flow rate of the flow control means (300). That is, the housing blocking member (312) can be rotated in one direction according to the rotation of the rotary opening/closing dial (320) to seal a different number of bypass inflow holes (202a) at each stage.

First, if the user wants to remove residual chlorine in the incoming raw water to 40% or less, the rotary opening/closing dial (320) can be adjusted to 7 stages of the bypass inflow hole (202a) in one direction. If the user wants to remove residual chlorine in the incoming raw water to 95% or more, the rotary opening/closing dial (320) can be adjusted to 0 stages of the bypass inflow hole (202a) in one direction.

In addition, in case the user wants to control the residual chlorine of the raw water being supplied to the range of 50 to 95%, the rotary opening/closing dial (320) can be unidirectionally adjusted from 4 stages to 1 stage of the bypass inflow hole (202a). That is, according to the present invention, as shown in FIGS. 14 and 15, the user can easily control the number of bypass inflow holes (202a) by opening or closing them to control the chlorine concentration of the raw water being supplied to the range.

It will be understood that the embodiments of the present invention are not necessarily limited to the above-described embodiments, and that various modifications and implementations within an equivalent scope are possible by those skilled in the art to which the present invention pertains. Therefore, it will be said that the true scope of the rights of the present invention is determined by the claims set forth below.
