Problems solved by technology

When the housing cover 20 is supported on one side of the filter housing 10 by the jig, incomplete welding may occur due to the deviation of the jig
[0008] In addition, the welding rib 22 has three surfaces, that is, two side surfaces and an end surface, thus making the welding time increase
[0009] In addition, it is difficult to determine whether the filter housing and the housing cover are properly welded
Therefore, when a slight welding error occurs in the filter assembly, additional testing is required to determine whether there is a welding failure, thereby reducing production capacity and requiring additional equipment

Embodiment Construction

[0034] Hereinafter, a filter assembly of an exemplary embodiment of the present invention will be described in detail.

[0035] figure 1 is a perspective view showing a filter assembly. figure 2 Yes figure 1 An exploded cross-sectional view of the filter assembly shown.

[0036] refer to figure 1 and figure 2 , the filter assembly 100 includes a filter housing 110 , a filter member 120 and a housing cover 130 .

[0037] The filter housing 110 is hollow. The water inlet housing cover 111 may be integrally formed with the water inlet side of the filter housing 110 . The filter housing 110 may have a cylindrical shape.

[0038] The water inlet pipe 112 may protrude from the water inlet housing cover 111 so as to be connected to a purification pipe (not shown). A plurality of supporting ribs (not shown) may be radially formed inside the water inlet housing cover 111 . Thus, water can flow between the supporting ribs.

[0039] The filter member 120 is detachably arra...

Abstract

There is provided a filter assembly that can reduce the thickness of a filter housing and the weight of the filter assembly. A filter assembly may include: a filter housing having a hollow therein and a welding rib provided along a periphery of one side thereof; a filter member arranged inside the filter housing and filtering water flowing into the filter housing; and a housing cap having a welding recess in which the welding rib is inserted, the welding recess smaller than the welding rib so that the welding rib is welded to the welding groove as both sides of the welding rib are rubbed against both sides of the welding recess.

Description

technical field [0001] The present invention relates to a filter assembly. Background technique [0002] In general, water treatment devices filter water to remove heavy metals or foreign matter contained in the water. Examples of the water treatment device may include a water purifier with a water purification system, a washing basin, a humidifier, a dishwasher, and a refrigerator. [0003] At least one filter assembly may be installed in the water treatment device to filter the water. In the filter assembly, the housing cover may be welded to the filter housing when the filter member is inserted into the filter housing. Here, the filter housing and the housing cover are produced separately using molds and then welded together. [0004] Figure 7 It is a figure which shows the connection structure which consists of a filter case and a case cover in a conventional filter assembly. [0005] A welding groove 12 is formed on an outer edge of one side of the filter case 10 ....
