Description

Sanitary water pack for preventing contamination of water storage tank used in water purifier and method for disinfecting purifier using the same}

The present invention relates to an antifouling sanitary water bag for a water purifier storage tank, and more particularly, to an antifouling sanitary water bag for a water purifier water storage tank that prevents purified water temporarily stored in a water storage tank of a water purifier from being contaminated by bacteria through external air. It is about. The present invention also relates to a water purifier disinfection method using the sanitary water bag to provide clean purified water without contamination of bacteria.

Conventional cold and hot water purifiers or storage type water purifiers are very excellent in water purification function, but the problem that the bacteria are frequently detected in the user drinking water. This is because the purified water is temporarily stored in the water storage tank of the water purifier while exposed to external air.

The reason for storing the purified water temporarily in the water storage tank in the water purifier is, firstly, to obtain the instantaneous supply shortage through storage because the water purification speed of the water purifier cannot keep up with the instantaneous usage of the user. In order to obtain the necessary pressure at the time of discharge through the potential energy by appropriately raising the height, and thirdly, if there is no water storage tank, the supply speed of purified water must be increased. Therefore, it is required to install components that withstand high water pressure. Because it does not.

Therefore, most cold and hot water purifiers or storage water purifiers have a reservoir tank at the top. However, when water is discharged from the storage tank, air must flow from the outside into the storage tank, and thus, the purified water accumulated in the storage tank is contaminated by external air.

1 is a view for explaining a conventional water purifier. As shown in FIG. 1, the purified water 60 purified by the filter 10 and stored in the water storage tank 20 via the water supply pipe 30 may be a hot water pipe 21 and cold water by itself in order to lower potential energy. It is introduced into the hot water tank 40 and the cold water tank 50 through the pipe (22). When the hot water drain cock 45 or the cold water drain cock 55 is opened, the hot water or cold water stored in the hot water tank 40 and the cold water tank 50 is discharged to the outside and stored in the water storage tank 20 as much as the discharge amount thereof. The purified water 60 spontaneously flows back into the hot water tank 40 or the cold water tank 50 by gravity.

Supplying purified water 60 to the water storage tank 20 through the water pipe 30, or smoothly inflow of the purified water 60 into the hot water tank 40 or the cold water tank 50 from the water storage tank 20 In order to flow out of the outside air to the reservoir tank 20 should be made. Therefore, the upper surface of the reservoir tank 20 is provided with an air distribution port 25, when the water flows in and out of the water storage tank 20, the outside air through the air distribution port 25 as much as the volume change according to the increase and decrease of the storage amount It goes in and out of water.

In the process of inflow and outflow of external air, various pollutants such as various bacteria and dusts in the atmosphere are introduced into the storage tank 20. In addition, cockroaches and ants enter the air distribution port (25). Therefore, no matter how excellent the performance of the filter 10, the user drinking water is likely to be contaminated by all kinds of pollution sources.

Therefore, the water tank 20 should be periodically cleaned, but until now, it is difficult to sterilize the inside of the water tank 20 due to its structure, so that only visible impurities are kept at the level of washing with water or a detergent. Even when washing with a cleaning agent, since the cleaning agent is not completely removed after washing, there is a high possibility that the cleaning agent is included in the water that the user eats.

Recently, many water purifier companies have recognized the seriousness of this problem and sealed the air outlet 25 with foreign substances such as sponge or non-woven fabric, but this prevents insects from accessing but prevents common bacteria from floating in the air. There is a limit.

Therefore, the problem to be solved by the present invention, by fundamentally blocking the exposure of purified water to the external air in the storage tank can not only prevent contamination of the purified water by external air, but also the flow of water located after the storage tank It is to provide an antifouling sanitary water bag for a water purifier reservoir tank suitable for removing contaminants on the path.

In addition, the problem to be solved by the present invention is to provide a water purifier disinfection method for supplying clean purified water without contamination such as bacteria to the user by using the sanitary water bag.

The antifouling sanitary water bag for a water purifier storage tank according to the present invention for achieving the above object is made of a flexible material, it is characterized in that the water inlet and outlet are provided and the disinfectant contained therein.

It is preferable that the purified water inlet is installed above, and the purified water inlet is installed below. In some cases, the purified water inlet and outlet may be installed as a single inlet.

The flexible material has an elastic force, more preferably made of a non-toxic material.

The disinfectant may be included in the water bag in a liquid or powder form, or may be coated on the inner wall of the water bag.

Purifier disinfection method according to the present invention for achieving the above object is made of a flexible material, but the sanitary water inlet and outlet of the sanitary water bag containing a disinfectant therein so that the water inlet and outlet of the water purifier storage tank are respectively connected to the sanitary Installing a water bag inside the water purifier storage tank; Supplying water to an inlet of the reservoir tank to expand the sanitary water bag so that the disinfectant is dissolved in the water; And a disinfecting step of disinfecting the water flow path after the purified water outlet of the sanitary water bag by discharging the water in which the disinfectant is dissolved to the outside by opening a drain cock last connected to the outlet of the water purifier storage tank. Characterized in that.

Installation of the sanitary water bag is preferably made in accordance with the filter replacement time of the filter located in front of the water purifier reservoir tank.

According to the present invention, it is possible to almost completely solve the problem of contaminated water in the storage tank due to contact with external air, and save time consuming tank cleaning time by replacing the sanitary water bag when replacing the filter of the filter. You can do it. In addition, the disinfection coating is applied to the sanitary water bag so that the inside of the water flow pipe located after the sanitary water bag can be disinfected through pre-disinfection work so that the user can be provided with clean water even when using the water purifier for a long time. do.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail. The following examples are only presented to understand the content of the present invention, and those skilled in the art will be capable of many modifications within the technical spirit of the present invention. Therefore, the scope of the present invention should not be construed as limited to these embodiments.

2 is a schematic view for explaining the water purifier is installed sanitary water bag 70 according to the present invention, Figure 3 is a schematic view for explaining the sanitary water bag 70 of FIG. In the drawings, the same reference numerals as in FIG. 1 denote components that perform the same function, and a repetitive description thereof will be omitted.

2 and 3, the sanitary water bag 70 in which the purified water inlet 73 and the outlets 71 and 72 are provided inside the storage tank 20 is provided with a sanitary water bag 70. The purified water inlet (73) is connected to the water pipe (30) communicating with the reservoir tank (20), and the purified water outlet (71, 72) is the hot water pipe (21) and cold water pipe (22) of the reservoir tank (20). Is connected to.

Therefore, the purified water purified by the filter 10 is stored in the sanitary water bag 70 through the water pipe 30, and when the user opens the hot water drain cock 45 or the cold water drain cock 55. It is discharged to the outside. When the hot water draining cock 45 or the cold water draining cock 55 is opened, the sanitary water bag 70 is air-flowing port in order for the purified water 60 of the sanitary water bag 70 to be spontaneously discharged by gravity. It is preferable to be made of a flexible material capable of changing the volume due to the inflow of air through (25). More preferably, it is preferably made of a material capable of contraction and expansion as a balloon, as described later in FIG. 5. In addition, it is preferable to be made of a material stable to corrosion or chemical reaction, such as a non-toxic polymer material. Here, it is preferable that the water storage tank 20 is not a metal tank as in the prior art because the purified water does not directly contact. For example, the water storage tank 20 may be made of plastic or in the form of a basket.

In addition, the water purification inlet 73 of the sanitary water bag 70 is preferably installed above the sanitary water bag 70 in order to smoothly fill and discharge the purified water 60, and the purified water outlets 71 and 72. Is preferably installed below the sanitary water bag (70). However, the position and number of the inlet 73 and outlet 71, 72 of the purified water does not limit the technical spirit of the present invention. In addition, when the purified water inlet 73 is installed above the water bag 70, it is preferable that the purified water inlet 73 is made of a structure that can be stretched in accordance with the contraction and expansion of the water bag (70). Do.

According to the present invention, the sanitary water bag 70 may be replaced without having to wash the water storage tank 20. However, if the water purifier is used for a long time, the paths through which purified water flows, such as the water tank 21, the hot water pipe 21, the cold water pipe 22, the hot water drain cock 45, and the cold water drain cock 55, are bacteria or fine contaminants. The hygiene is still not sanitary, so the user will eventually drink unsanitary water. Therefore, in order to prevent this, the disinfectant may be included in a liquid, granular or powder form in the sanitary water bag 70 or the disinfectant coating 80 on the inner wall before use. As a disinfectant, chlorine or iodine, which are generally used, may be used. Here, the disinfectant is preferably harmless to the human body at low concentrations, it is preferable to smell in a certain concentration or more.

The inclusion of the disinfectant in the sanitary water bag 70 is also to prevent the sanitary water bag 70 itself from being contaminated at the stage of distribution, storage, sale, etc. of the sanitary water bag 70 to prevent its original function.

In order to detect a leak of the sanitary water bag 70, the leak detection sensor 90 is installed on the bottom of the water storage tank 20, and the result is notified to the user by a notification means installed in an external case (not shown). If the sanitary water bag 70 will be leaked, and the water leaked at this time will flow to the bottom of the reservoir tank 20, the leak detection sensor 90 is preferably installed on the bottom surface of the reservoir tank (20). As the leak detection sensor 90, a capacitance sensor may be used. This is because the change in capacitance will be different when the sanitary water bag 70 touches the capacitive sensor and the water directly touches the capacitive sensor.

In addition, the water storage tank 20 further includes a sensor capable of measuring the shrinkage of the sanitary water bag 70 or the weight of the purified water introduced into the water bag 70. The former is a contact sensor installed on the upper side of the reservoir tank 20 to detect the inflow of water into the water bag 70 is expanded or contracted to a predetermined size or more to measure the water level of the purified water. The latter is a pressure sensor installed on the bottom of the reservoir tank 20 to indirectly measure the level of purified water by detecting that water enters the water bag 70 and the weight of the water bag increases or decreases more than a predetermined level. These sensors are connected to a control device to control the supply of purified water.

4 is a flowchart illustrating a water purifier disinfection method according to the present invention. First, the purified water inlet 73 and outlet 71 and 72 of the sanitary water bag 70, which is coated with the disinfectant 80, are coupled to the water supply pipe 30, the hot water pipe 21, and the cold water pipe 22, respectively. It is installed in the reservoir tank 20 (S1). At this time, the filters installed at the tip of the water storage tank 20 are also replaced.

Then, the tap water is supplied into the sanitary water bag 70 through the flowing water pipe 30 so that the sanitary water bag 70 is fully inflated (S2). Then, the disinfectant is dissolved in the disinfection coating 80 of the sanitary water bag (70). The amount of disinfectant is determined to be an appropriate concentration in consideration of the maximum capacity of the sanitary water bag (70). For example, the concentration of the disinfectant is maintained at a concentration capable of sterilization, the concentration of the disinfectant remaining in the sanitary water bag 70 after the disinfection is finished so as not to feel harmless or unpleasant to the human body at all.

Thereafter, the cold water drain cock 45 and the hot water drain cock 55 are opened (S3). Then, the purified water 60 containing the disinfectant is discharged to the outside while the hot and cold water drain pipes 21 and 22 and the cold and hot water drain cock 45 and 55 are disinfected. After this disinfection step (S2) passes the sanitary water bag 70 again in the normal manner as in the normal case and is used normally (S5). After the proper period of use, replace the sanitary water bag (70) (S6). At this time, it is efficient to replace the filter with the filter filter of the filter 10.

5 is a view for explaining the form of the sanitary water bag (70). As shown in (a) of FIG. 5, if the bottom edge A is angled or between two water outlets 71 and 72 (B) is flat, water may accumulate and may not be hygienic. Therefore, it is preferable to gently incline the edge A as shown in FIG. 5 (b) so that water does not accumulate therein.

Furthermore, as shown in FIG. 5C, only one purified water outlet 71 may be installed to prevent water from accumulating between the two outlets. When there is one outlet, it will branch to the hot water pipe 21 and the cold water pipe 22 after the outlet.

In order to ensure that the bottom edge (A) has a gentle inclination, the shape at the time of expansion of the sanitary water bag (70) may be designed in advance, but the sanitary water bag (70) is made of an inflatable material such as a balloon to It may be allowed to isotropically expand when filled. The latter case is more preferable because the sanitary water bag can be installed regardless of the shape of the water storage tank 20. Even if the sanitary water bag 70 isotropically expands, the sanitary water bag 70 eventually comes into contact with the water storage tank 20 to have a shape similar to that of the water storage tank 20, but the edge is gently inclined. At this time, it is preferable that the sanitary water bag 70 does not have an elastic force until it is expanded in a predetermined form. For example, if excessive elastic force is applied to the sanitary water bag 70 before reaching the maximum water level, it is because the inflow of purified water becomes difficult or when the purified water flows out when it is not desired.

In addition, as shown in (d) of FIG. 5, it is preferable that stoppers 73a and 71a are provided at the purified water inlet 73 and the outlet 71 of the unused product. And if the three-way valve 75 that can control the flow direction as shown in Figure 5 (e) is installed, one outlet inlet 74 may perform the function of the inlet 73 and outlet 71.

According to the present invention, it is possible to almost completely solve the problem of contaminated water in the water storage tank 20 due to contact with external air, and by replacing the sanitary water bag 70 at the time of replacing the filter of the filter 10, This will save a lot of time to clean the storage tank 20. In addition, since the sanitary water bag (70) has a disinfection coating (80), it is possible to disinfect the inside of the water flow pipe located after the sanitary water bag (70) through pre-disinfection operation, even when using the water purifier for a long time. The user can be provided with clean water.
