Description

Fluid treatment system

The present invention relates to a fluid processing system, and more specifically, to a fluid processing system in which fluids of different temperatures can be filtered and then supplied to a demand location, and the system for filtering each fluid can be effectively cleaned.

As the standard of living improves, the number of devices installed to filter and use water in final demand areas such as homes is increasing. The above devices, which can be represented by water purifiers, etc., are configured to filter water delivered to the final destination through various routes such as pipes just before it is discharged.

Water purifiers are often provided for drinking water. In other words, the water discharged from the water purifier is mainly used for drinking by users. At this time, the water delivered to the water purifier may be mixed with various microorganisms or impurities, and the water purifier is equipped with various types of filters to filter out the microorganisms or impurities.

Recently, requirements related to the quality of water used not only for drinking but also for domestic purposes, such as showering, washing dishes, laundry, etc., are increasing. Accordingly, technologies are being developed to filter not only the water immediately before being discharged, but also the supplied water itself and then supply it to the final destination.

Meanwhile, various components provided in the water purifier to filter water, such as filters, require maintenance as the water purifier continues to be used. Generally, maintenance of the filters, etc. is performed by way of replacement.

If a home is equipped with a water purifier, the user can periodically open the water purifier to check the status of the filter. Additionally, recently, water purifiers have been configured to directly output information about the status of the filter, allowing users to easily recognize when it is time to replace the filter.

However, the device for filtering the water supplied to the final demand point described above is installed outside the final demand point, such as a home. Additionally, for reasons such as aesthetics and space utilization, the device is generally installed in a location that is not easily accessible to users.

Moreover, the above device must filter a large amount of water compared to water purifiers provided at home. Therefore, the filter provided in the device may require more frequent maintenance compared to the water purifier provided in the home. As a result, frequent replacement of filters may require a lot of time and money.

Additionally, there may be cases where users request water of different temperatures depending on need. In this case, when water is supplied from a single water source, the user must additionally provide a separate member for heating or cooling the water.

US Patent No. 11,053,149 discloses a POE type water sanitation system for improving the quality of water supplied to buildings. Specifically, a POE that filters water supplied from a water source and a bypass line that diversifies the paths of filtered water supplied into a building are disclosed.

However, the bypass line disclosed in the prior literature is configured to form a water path after water has already been supplied into the building. In other words, the above prior literature does not suggest a method for configuring various temperatures of water supplied into the building through POE.

US Patent Publication No. 2013/0277294 discloses a filter system used in a POE type water purifier. Specifically, a filter system capable of supplying and filtering water through one or more filters among a plurality of filters is disclosed.

However, the filter system disclosed in the above prior literature only discloses information about forming flow paths of a plurality of filters for use in a POE type. In other words, the prior literature does not suggest a method for managing the filter system provided in the POE type water purifier.

Furthermore, the above prior literature does not suggest a method for reducing the time and cost required for maintenance by extending the replacement cycle of the filter provided for water filtration.

Although not shown, the first inlet flow path IF1 and the second inlet flow path IF2 may extend so as not to pass through the first filtering unit 200a and the second filtering part 200b, respectively. In other words, the fluid can be supplied directly to the demand point (D) without being filtered by the filtering unit 200. It will be understood that the passages may be utilized when the filtering unit 200 or the first pipe 410 in communication with the filtering unit 200 is damaged, maintained, or replaced.

Although not shown, the fluid delivered from the water source (S) may flow into the filtering unit 200 through the second communication part 222 and be discharged after cleaning the filter member 240.

The first cleaning flow path CF1 may be defined as a flow path through which the filter member 240 of the first filtering unit 200a provided in the first processing module 11 is cleaned. It will be understood that the fluid forming the first cleaning flow path CF1 is the fluid filtered by the second processing module 12.

At this time, the first processing module 11 is blocked from communicating with the water source (S), thereby preventing backflow of the filtered fluid to the water source (S). Additionally, the first filtering unit 200a can be cleaned with the fluid previously filtered by the second processing module 12, so cleaning efficiency can be improved.

It flows. At this time, the variable flow path member 330 of the second processing module 12 is maintained at the first position P1 (see (a) of FIG. 10).

Accordingly, the introduced fluid is filtered by the second filter 200b and then flows into the second outflow line 12c through the first pipe 410 on the downstream side of the second processing module 12. The first inlet valve 11b is controlled to close the first inlet line 11a, thereby blocking communication between the water source S and the first treatment module 11.

At this time, the outflow valves 11d and 12d are controlled to close the outflow lines 11c and 12c, and communication between the first and second processing modules 11 and 12 and the water supply source D is blocked. Additionally, the cleaning valve 14 is controlled to open the cleaning pipe 13, so that the first outflow line 11c and the second outflow line 12c communicate with each other.

The fluid flows radially outward of the filter member 240 and passes through the hollow fiber 241, separating foreign substances accumulated in the hollow fiber 241. The flowing fluid and foreign substances flow toward the discharge pipe 450 along the extension direction of the filter member 240. Fluid and foreign matter may pass through the discharge pipe 450 and flow into the water storage tank (R).

15 to 16, a second cleaning flow path CF2 formed in the fluid processing system 10 according to an embodiment of the present invention is shown. The second cleaning flow path CF2 may be defined as a flow path through which the filter member 240 of the second filtering unit 200b provided in the second processing module 12 is cleaned. It will be understood that the fluid forming the second cleaning flow path CF2 is the fluid filtered by the first processing module 11.

At this time, the second processing module 12 is blocked from communicating with the water source (S), thereby preventing backflow of the filtered fluid to the water source (S). Additionally, the second filtering unit 200b can be cleaned with the fluid previously filtered by the second processing module 12, so cleaning efficiency can be improved.

Accordingly, the introduced fluid is filtered by the first filter 200a and then flows into the first outflow line 11c through the first pipe 410 on the downstream side of the first processing module 11. The second inlet valve 12b is controlled to close the second inlet line 12a, thereby blocking communication between the water source S and the second treatment module 12.

At this time, the outflow valves 11d and 12d are controlled to close the outflow lines 11c and 12c, and communication between the first and second processing modules 11 and 12 and the water supply source D is blocked. Additionally, the cleaning valve 14 is controlled to open the cleaning pipe 13, so that the first outflow line 11c and the second outflow line 12c communicate with each other.

Accordingly, the filtered fluid does not flow to the reservoir D, but flows along the cleaning pipe 13 and the second outflow line 12c connected thereto and flows into the second treatment module 12. The introduced fluid may form flow paths in various shapes along the piping section 400 of the second processing module 12 and may flow into the second filtering section 200b.

Accordingly, the fluid that has reached the inner space of the cover body 310 flows into the filtering space 211 inside the second filtering unit 200b through the second communication part 222.

Thereafter, the process in which the fluid is discharged after cleaning the filter member 240 of the second filtering unit 200b is the same as the above-described first cleaning flow path CF1.
