Description

[Detailed Description of the Invention] L! The present invention relates to a water purification filter for an automatic ice making device, and more particularly to a water purification filter for an ice making device that is housed in a household refrigerator and automatically performs everything from water supply to ice removal.

As shown in FIG. 1, an automatic ice making device housed in a household refrigerator is comprised of a water supply unit 10 having a water purification function, an ice making unit 11, and an ice storage box 12.

In the figure, reference numeral 14 denotes a rectangular box-shaped open tank with an open upper surface, which constitutes the water supply unit 10. A water supply bomb 15 is disposed above this open tank 14, and a water supply pump 1
5 is a suction pipe 1 whose tip is housed in an open tank 14;
6 is connected. Also, a sealed kunk 17 filled with water
is supported by a shelf 18 in the refrigerator and disposed above the open tank 14, and a water purification filter 20 is installed inside the lid 19 of the closed tank 17 as shown in FIG. As shown in FIG. 4, the water purification filter 20 is composed of a case part 21 and a filter part 22, and the filter part 22 further includes an activated carbon felt 22a that removes impurities and lowers the concentration of residual chlorine, and an activated carbon felt 22a that removes impurities and lowers the concentration of residual chlorine. The activated carbon felt 22a has an antibacterial filter 22b sandwiched therebetween, and the upper and lower portions of the activated carbon felt 22a are covered with a non-lined cloth 23.

In the automatic ice making device described above, when the ice cubes in the ice tray 13 are released into the ice storage box 12, a certain amount of purified water is supplied to the ice tray 13 from the water supply unit 10. Furthermore, the tank 1 is opened by supplying water to the ice tray 13.
When the amount of water in the tank 4 decreases, purified water is supplied from the closed tank 17 through the water purification filter 20 into the open tank 14.

In the conventional water purification filter 20 for automatic ice making equipment described above, the filter part 22 is assembled by overlapping the activated carbon felt 22a and the antibacterial filter 22b, which takes time and effort to assemble, and is difficult to assemble in terms of materials. However, there were issues such as unavoidable cost increases and poor production efficiency.

The present invention was invented in view of the above-mentioned problems, and eliminates the need for the assembly process of the filter section, thereby improving productivity and reducing costs. It is an object of the present invention to provide a water purification filter for an automatic ice making device that can fully perform the functions.

Section 'F To achieve the above object, the water purification filter for an automatic ice making device according to the present invention comprises a case part and a filter part, and the filter part includes a felt layer containing activated carbon and silver activated carbon. It is characterized by being configured.

According to the above-described structure, the filter part is formed as a single felt layer formed by mixing activated carbon and silver activated carbon, so that the labor of the assembly process can be saved.

In addition, activated carbon removes impurities and reduces the concentration of residual chlorine, and silver activated carbon has antibacterial effects, so it does not impair its function as a conventional filter.

Embodiments of the water purifying filter for an automatic ice making device according to the present invention will be described below.

As shown in FIG. 1, the automatic ice making device is comprised of a water supply unit 10 having a purifying function, an ice making unit 11, and an ice storage box 12.

The water supply unit 10 includes a rectangular box-shaped open tank 14 with an open top, a pump 15 for supplying water to the ice tray 13, and a closed tank 17 supported by a shelf 18 inside the refrigerator. The open tank 14 has a partition wall 24 inside thereof, and is divided into a suction chamber 25 and a water receiving chamber 26 by the partition wall 24. A hole 27 is provided in the lower part of the partition wall 24 to communicate the suction chamber 25 and the water receiving chamber 26.
An outflow port receiving portion 28 is formed approximately at the center of the bottom surface of the water receiving chamber 26 and protrudes from the bottom surface. An electric water supply pump 15 having a discharge pipe 29 and a suction pipe 16 for supplying water to the ice tray 13 is disposed above the suction chamber 25, and the tip of the pump suction pipe 16 is connected to the suction chamber 25. It is designed to be accommodated in In addition, a lid portion 19 is formed at the water inlet/outlet portion 17a of the sealed tank 17.
9 includes a shaft 31, a spring 32, and a valve 33, and as shown in FIG.
An air vent pipe 34 for feeding air into the interior of the housing 7 passes through the housing.

The water filter 30 is attached to the case part 3 as shown in FIG.
0a and a filter section 30b, the filter section 30b
The felt layer includes an integrally formed felt layer containing activated carbon and silver activated carbon. Furthermore, the filter section 30
The surface of b is covered with a nonwoven fabric 23 to prevent impurities contained in water from passing through. The filter part 30b is the case part 30
The non-woven fabric 23 and the case portion 30a are integrally molded or welded, and the filter portion 30b does not require the effort of assembling it as in the conventional case.

In the automatic ice making apparatus having the above-mentioned configuration, the ice making tray 13 provided in the freezer compartment is rotated over time by the operation of the drive device 35 at a rate of, for example, once every two hours. When the ice tray 13 is twisted, the ice cubes are released and stored in the ice storage box 12 disposed below the ice making section 11.

The water supply pump 15 is linked to the drive device 35, and when the ice removal operation is completed and the ice tray 13 returns to its original position, the water supply pump 15 stops supplying water from the suction chamber 25 to the ice tray 13. It begins.

When the water level in the suction chamber 25 decreases, water is supplied from the water receiving chamber 26 through the hole 27 formed in the partition wall 24.

When the water level in the water receiving chamber 26 falls below a certain level, the sealed container 1
7 is set in the open tank 14, the shaft 31 hits the outlet receiving part 28, the spring 32 is compressed, and the valve 33 is raised, so air enters the sealed tank 17 from the air bleed pipe 34, and the Divided water is water filter 3
0 and is supplied to the water receiving chamber 26.

In the water purification filter 30, impurities are removed by a filter portion 30b made of a felt layer containing activated carbon and silver activated carbon, and while the residual chlorine concentration is reduced, antibacterial treatment is also performed.

As a result, purified water is used to make ice and delicious ice is obtained.

As is clear from the above explanation, the water filter for automatic ice making equipment according to the present invention is a felt containing activated carbon that removes impurities and reduces the concentration of residual chlorine and silver activated carbon that has an antibacterial effect. Since the filter section includes layers, it is possible to save time and effort in assembling the filter section, increase productivity, and keep material costs low, making it possible to obtain a water purification filter at low cost.

Also, since the ice is made with water purified by activated carbon and silver activated carbon, delicious water can be obtained.
