Filter fixing device of water purifier {FILTER FIXING APPARATUS OF WATER PURIFIER}

The present invention relates to an apparatus for fixing a filter for use in a water purifier, and more particularly, to an apparatus for fixing a filter for a housing type undersink water purifier.

Currently, a water purifier installed in a home or an office has a basic function of filtering raw water such as tap water or natural water and providing it as warm or cold water. The water purifier is equipped with a plurality of filters to remove harmful substances to the human body, including suspended solids mixed in raw water, to deodorize odors and to sterilize bacteria causing waterborne diseases.

That is, in the water purifier, a pre-carbon filter which performs a filtering function by adsorption action by a fine pore of a sediment filter and a carbon (activated carbon) block to sequentially form raw water through the purified water. ), Post-carbon filters, membrane filters and UV-filters are optionally applied.

If the water purifier is classified according to the type in which the water purifier is used, it can be classified into a count top type water purifier and an undersink type water purifier.

The count-top water purifier is composed of its own housing and used on the top of the sink, and the under-sink water purifier is a water purifier installed in the sink to discharge the purified water through the facet installed in the sink.

In other words, the undersink water purifier is a means for purifying tap water or ground water (hereinafter referred to as 'tap water') supplied from a tap water, which is installed inside the sink, and the purified water is installed in the sink. Discharge through.

Meanwhile, the undersink type water purifier may be further divided into a housing type and a box type according to the filter arrangement structure therein, and FIG. 1 illustrates a filter arrangement structure of the housing type undersink water purifier.

1 is an exemplary view showing a state in which a filter fixing device of a water purifier used in the related art is equipped with filters, and particularly, a state in which the filter fixing device of a housing type undersink water purifier is equipped with filters. 2 is an exemplary view showing a state in which the filter is separated in the filter failure device of the water purifier shown in FIG. 1.

As shown in FIG. 1, the filter fixing device 10 of the conventional water purifier includes a plurality of fixing parts 12 to which the filters are fastened and a shelf part 11 to which the plurality of fixing parts are fixed. have.

That is, among the various types of filters described above, the filters 20 which are required to be used in an upright standing state or need to be stored in a structurally standing state are fixed to the fixing part 12, respectively. The filters 30 are fixedly arranged on the upper surface of the shelf 11.

Here, the fixing part 12 is fixedly disposed on the lower surface of the shelf part 11, and the fixing part 12 and the filter 20 are coupled in the structure of bolts and nuts.

The fixed part 12 is connected to the transfer pipe 13, and performs a function of transferring the raw water between each filter.

On the other hand, the filters need to be cleaned or replaced regularly. 2 shows a state in which the filter 20 is separated or combined in the filter fixing device of the water purifier having the structure as described above, the user inserts the opener 40 or a hand between the filter and the filter, and then moves the filter to the right. Alternatively, by rotating to the left, the filter 20 can be coupled to or separated from the fixing part 12.

However, due to the structure of the undersink type water purifier intended for storage in a narrow sink, the distance between the filters 20 can only be narrowed, so that the user can insert the opener 40 or a hand to insert the filter 20. Rotating is not easy.

Furthermore, since the raw water is filled in the filters 20 which are in use, and the weight of the filters 20 filled with the raw water is about 1.5 kg to about 2 kg, the fixing parts arranged at narrow intervals ( Coupling the filter to 12) or separating the filter from the fixing part 12 is very difficult and inconvenient for housewives.

SUMMARY OF THE INVENTION An object of the present invention for solving the above problems is to provide a filter fixing device for a water purifier, in which a fixing part to which a filter is fixed is formed to be rotatable.

The present invention for achieving the above object is a plate-shaped shelf portion, a plurality of extensions extending in the vertical direction at regular intervals from the lower surface of the shelf portion, at least one side of each of both sides of each of the extension portion Between the coupling portion formed and the two extension portions can be rotated in connection with the two coupling portions formed in each of the two extensions, and includes a plurality of fixing portions to which the filter is fixed.

The invention is coupled to the shelf to be rotatable in the front and rear or left and right directions to which the filter is fixed, thereby allowing the user to facilitate the process of fixing the filter to the fixing part or separating the filter from the fixing part. It works.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is an exemplary view showing a state in which the filter fixing device of the water purifier according to the present invention mounts the filters. In particular, FIG. 3 is an exemplary view showing a state in which the filter fixing device of the housing type undersink water purifier is equipped with the filters. 4 is an exemplary view showing a state of use of the filter failure device of the water purifier shown in FIG. 3.

As shown in FIG. 3, the filter fixing device of the water purifier according to the present invention includes a plate-shaped shelf 110 and a plurality of extensions 140 extending in a vertical direction at regular intervals from a lower surface of the shelf. And an extension line of two coupling parts respectively formed on the two extension parts between the coupling part 130 formed in a horizontal direction on at least one side of both sides of each of the extension parts, and the two extension parts. It is coupled to the two coupling parts to be rotated by, a plurality of fixing part 120 is fixed to the filter and the transfer pipe 150 for connecting the fixing part and the fixing part so that the raw water can be transferred. . On the other hand, the filter that can be used in the water purifier as described above, such as a sediment filter composed of a non-woven fabric and performs a function of filtering foreign matter of relatively small particles, such as sand or mud, such as activated carbon mainly composed of carbon , Pre-carbon filter and post carbon filter to remove chlorine particles and odor contained in raw water, and membrane filter to remove foreign substances and harmful substances by forming a plurality of pores of very small diameter. It may be used, it may be fixed to the fixing part 120 or disposed on the upper surface of the shelf 110 according to its characteristics.

The upper surface of the shelf 110 may be mounted with filters 300 that do not need to be used in a standing state or need not be stored in a standing state. The filters 300 perform a function of filtering raw water transferred from filters fixed to the fixing part 120, and may be a membrane filter or a post carbon filter.

As shown in FIG. 3, the extension part 140 extends vertically from the bottom surface of the shelf part 110 and is formed with one more number than the number of fixed filters. That is, since one filter is fixed between the extension part 140 and the extension part, the number of the extension parts 140 becomes one more than the number of the filters to be fixed. However, in general, since the number of filters fixed to the lower surface of the shelf 110 is three, it is preferable that four extensions are formed. On the other hand, it is preferable that the interval between the extension and the extension is set so that the fixing portion 120 can be smoothly rotated.

The coupling part 130 is for coupling the fixing part 120 to the extension part 140. The fixing part 120 is connected to the extension part 140 in a structure in which the fixing part 120 in a coupled state can be rotated. Combine. That is, the fixing part 120 is fixed to each of the two coupling parts 130 respectively formed on the two extension parts 140 between the two extension parts 140. On the other hand, the two coupling parts 130 are formed on the same horizontal plane, the fixing part 120 is the two coupling parts to be rotated by using a virtual axis on the extension line of the two coupling parts 130 as the rotation axis Respectively coupled to 130. In order to allow the fixing part 120 to be rotated as described above, the fixing part 120 and the coupling part 130 may be provided with an insertion protrusion and an insertion groove. For example, the fixing part 120 may be provided with two cylindrical insertion protrusions 121 protruding in the same horizontal plane as the two coupling parts 130, each of the two coupling parts 130. An insertion groove 131 may be formed so that the insertion protrusion 121 may be inserted and rotated. However, the present invention is not limited thereto. Therefore, the insertion protrusion 121 and the insertion groove 131 may be formed in a structure opposite to each other. In addition, the coupling part 130 and the fixing part 120 may be formed in various configurations so that the fixing part 120 may be rotated using a virtual axis on the extension lines of the two coupling parts 130 as the rotation axis. have.

The fixing part 120 may be rotated in a state of being coupled to the two coupling parts 130 as described above, and the fixing part 120 may be attached to and fixed to the fixing part 120. The method of fixing the filter 200 to the fixing part 120 may also be made in various ways. In general, the fixing part 120 and the filter 200 may be coupled or separated in the structure of bolts and nuts. To this end, a thread is formed on one side of the fixing part 120 to be in contact with the filter 200, and a groove that can be coupled to the thread is formed at one side of the filter 200 to be in contact with the fixing part 120. And vice versa.

The transfer pipe 150 is for transferring raw water between the filters fixed to the fixed part 120, and connects the fixed part 120 and the fixed part. In addition, the transport pipe 150 is connected to any one of the two fixed portion 120 of the outermost fixed portion 120 disposed in the outermost is connected to the raw water supply pipe (not shown) to supply the raw water, and The transfer pipe 150 connected to the other fixing part 120 is connected to the filter 300 disposed on the upper surface of the shelf part 110.

On the other hand, Figure 4 shows a state in which the filter 200 is attached to the fixing part 120 in the filter fixing device of the water purifier as described above, it shows a state viewed from the 'A' direction of FIG. The filter detachably attached to the fixing part 120 may vary according to the function and configuration of the water purifier. For example, one sediment filter and two carbon filters may be fixed. That is, in the housing type undersink water purifier, raw water that has undergone the filtering process in the filters 200 fixed to the fixing part 120 is transferred to the filters 300 placed on the upper end of the shelf part 110 and filtered. Since it is discharged as purified water, the filters fixed to the fixing part 120 will be filters placed at the front end of a general water purifier, and such filters may be a high turbidity filter, a sediment filter, and a carbon filter.

A user who wants to remove the filter 200 in the filter fixing device of the water purifier according to the present invention first rotates the filter 200 as shown in FIG. 4 while the filter 200 is held by an opener or a hand.

The above process is simply grabbing the filter and pulling in its own direction, there is no hassle such as rotating the filter in a narrow space as in the prior art.

Further, in the state where the filter 200 protrudes into the space through the above process, not only a space for rotating the filter 200 can be secured, but the filter is still fixed to the fixing unit 120. Because it is a state, it does not need to be given much power.

Therefore, the user may rotate the filter 200 in a state as shown in FIG. 4 to detach the filter 200 from the fixing part 120.

The process of fixing the filter 200 to the fixing unit 120 may be performed through the reverse process of the above process.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the technical spirit of the present invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification but should be defined by the claims.
