[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric water purifier, and more particularly to a water filter.

[0002]

2. Description of the Related Art A water purification filter is provided at a position higher than a full water level in an inner container of an electric pot, and water in the inner container pumped by an electric pump is dropped from above the water filter. Electric water purifiers are conventionally known.

[0003] The water purification filter used in the pot as described above contains a purifying agent inside a case having openings on the upper and lower surfaces, and a net made of metal or the like is provided in each opening to prevent leakage of the purifying agent. It is designed to allow water to pass freely while preventing water from flowing out.

[0004]

In the electric water purifier using the water purifying filter as described above, if hot water comes into contact with the purifying agent during use, air bubbles are generated from the purifying agent. Required. If this means is insufficient, air bubbles accumulate inside the case, and the air bubbles prevent the hot water from contacting the purifying agent, so that there is a problem that the water purification ability cannot be exhibited. For this reason, conventionally, as a metal net stretched over the opening, a metal net having a size such that the air bubbles easily escape was used, and the air bubbles were allowed to escape to the outside through the mesh.

However, when the mesh of the metal mesh becomes larger than a certain size, the particle size of the purifying agent must be large enough not to fall out of the mesh, so that the type of the purifying agent is limited. There was a problem that the cost was high. In addition, such a metal net is an expensive component, and has been one factor that makes the cost of the entire product expensive.

In view of the above, the present invention is designed so that the structure of the water purification filter is devised so that the particle size of the purifying agent is not restricted, and that the bubbles generated from the purifying agent can be reliably discharged to the outside. An object of the present invention is to provide an electric water purifying pot.

[0007]

According to the present invention, a water purification filter is provided at a position higher than a full water level of an inner container, and the water in the inner container pumped by an electric pump is subjected to the above water purification. In an electric water purifier configured to be dropped from the upper part of the filter, a configuration is provided in which a case for the water purifying filter is provided with an escape hole for bubbles generated from the purifying agent.

[0008]

[Function] Since air bubbles generated from the purifying agent when the purifying agent comes into contact with hot water escape from the escape hole of the case to the outside,
The contact between the hot water and the cleaning agent is not hindered. The opening of the case of the water purification filter is closed by a closing means having water permeability necessary for passing hot water, for example, a water-permeable closing sheet such as a nonwoven fabric.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, an electric water purifying pot according to an embodiment comprises an inner container 1, an outer container 2, and a lid 3, and a water purification filter 4 is provided inside the lid 3. An electric pump 5 is provided at the lower part of the inner container 1, and the electric pump 5 guides the water to the discharge port 8 or the water purification filter 4 through the water pump 6 and the switching device 7.

As shown in FIG. 2, the water purification filter 4 is removably housed in a housing 10 provided at the center of the middle plate 9 of the lid 3. A water passage pipe 11 is provided on the upper surface of the storage portion 10 and communicates with the switching device 7 via the water passage pipe 11.

As shown in FIGS. 3 and 4, the water purification filter 4 includes a case main body 12, a case lid 13, a purifying agent 14 housed inside, and upper and lower water-permeable closing sheets 15 and 16 made of nonwoven fabric. . The case main body 12 has a large number of openings 19 defined by ribs 18 projecting radially from a flat plate portion 17 at the center of the bottom surface.
Two male screw ribs 20 and 20 'for partially screw-fitting are provided partially. Also, each male screw rib 20, 20 '
Are provided with engagement holes 21 and 21 ′ for engaging with the case lid 13.

One engagement hole 21, that is, the engagement hole 21 which is on the discharge port 8 side when the water purification filter 4 is stored in the storage unit 10.
A plurality of air bubble escape holes 22 are provided between the hole and a male screw rib 20 below the hole. The reason why the bubble escape hole 22 is provided on the discharge port 8 side is that even if the water purification filter 4 is inclined by the opening of the lid 3 and the purifying agent 14 moves, the bubble escape hole 22 is not closed. is there. Thereby, clogging of the bubble escape hole 22 can be prevented, and even if the particle size of the purifying agent 14 is sufficiently large, the possibility of the purifying agent 14 getting caught in the bubble escape hole 22 can be reduced. The water-permeable closing sheet 15 is mounted on the opening 19, and the purifying agent 14 is stored thereon.

The case lid 13 is designed to drop into the inside of the case body 12, and has a flat plate portion 23 at the center.
And a large number of openings 25 defined by ribs 24 protruding radially from the flat plate portion 23, and two projections 26 engaging with the engagement holes 21, 21 ′ of the case main body 12 on the peripheral wall. , 26 ′ are provided, and the projections 26, 26 ′ are engaged with the respective engagement holes 21, 21 ′ of the case main body 12, whereby the case lid 13 is integrated with the case main body 12.
The water-permeable closing sheet 16 is attached to the upper surface of the opening 25 of the case lid 13.

A cover plate 28 made of a metal plate is attached to the lower surface of the case body 12 with screws 27. Thereby, the influence of heat on the water purification filter 4 is reduced.

2, reference numeral 29 denotes a lower plate of the lid 3, reference numeral 30 denotes a steam passage, reference numeral 31 denotes a hinge, and reference numeral 32 denotes a hook. By pulling up the hook 32, the lid 3 is opened around the hinge 31. You.

The electric water purifying pot of the embodiment is as described above. After the water heater is started, the electric pump 5 is operated to switch the water in the inner container 1 through the switching device 7 to the water pipe 11.
From the water filter 4.

The dropped water passes through the upper closing sheet 16, and the water dropped on the flat plate portion 23 is dispersed, and the water is dispersed to the case cover 1.
The cleaning agent 14 comes into contact with the purifying agent 14 through the opening 25, and falls into the inner container 1 from the lower closing sheet 15 through the opening 19 of the case body 12 and the hole 33 of the cover plate 28. If the temperature of the water rises while the above process is repeated for a required time, air bubbles are generated from the purifying agent 14, and the air bubbles are generated by the case body 1.
The air is discharged to the outside through the air bubble escape hole 22.

Although the bubble escape hole 22 in the above embodiment is formed by providing a hole in the peripheral wall of the case main body 12, the present invention is not limited to this configuration. May be set to be larger than the lateral width of the projection 26, and the gap between the two may be a bubble escape hole. Further, a notch may be provided in the upper edge of the case main body 12 and a space between the notch and the case lid 13 may be formed as a bubble escape hole.

[0019]

[Effects of the Invention] As described above, in the present invention, the air release hole is provided in the case of the water purification filter, so that the air bubbles generated by the contact of the purifying agent with the hot water are discharged to the outside through the release hole. Is done. For this reason, the closing sheet provided at the opening of the case only needs to have water permeability, and it is not necessary to discharge generated air bubbles. Therefore, an inexpensive sheet such as a nonwoven fabric can be used as the closing sheet. There is no limitation on the size of the particles, and an inexpensive purifying agent can be used. Therefore, there is an effect that the cost of the product can be reduced.
