Description

[Detailed description of the invention] [Industrial application field] The present invention, for example, filters out impurities such as pieces of batter mixed in tempura oil and oxides that increase due to heating, and restores the oil to a clean state. More specifically, it relates to a liquid filter in which a filter is provided at the bottom of a container so as to close a filtrate extraction port formed at the bottom.

[Conventional technology]

In this type of liquid filter, the filter is constructed by laminating a large number of plate-shaped filter materials each having a through hole in the center thereof, and a flat plate for a weight that can be placed on the top surface of the filter is provided. It is known that a downstream guide shaft is inserted into the through hole of the laminated filtration material and the filtrate extraction port of the container.
(Japanese Utility Model Publication No. 58-179075).

With this conventional liquid filter, when the filter becomes clogged while filtering liquids such as frying pan oil and it becomes necessary to replace it with a new filter, the flat plate with the flow guide shaft is first removed. Afterwards, the laminated filtration material must be removed in appropriate number units, and as a result, the number of replacement operations in the narrow space inside the container increases. There is a problem when the oil or residue gets on your hands and gets dirty.

[Problem that the invention attempts to solve]

An object of the present invention is to enable quick and easy filter replacement work.

[Means for solving problems]

The characteristic configuration of the liquid filter according to the present invention is that a support member is provided on which the filter can be mounted and that forms a flow path for guiding the fluid that has passed through the filter to the filtrate extraction port, and The member is provided with a handle that protrudes above the filter placed on the member, and its functions and effects are as follows.

[Effect]

If the filter becomes clogged while filtering liquid such as frying oil, the entire used filter can be taken out of the container by simply lifting the handle that projects above the filter. Moreover, when setting a new filter, the new filter can be mounted on the support member in a large space outside the container, so it can be set simply by lifting the handle and placing it into the container.

[Effect of idea]

Therefore, the number of replacement operations in a narrow space inside the container can be reduced as much as possible, so that the filter replacement work can be done quickly and easily while keeping hands as dirty as possible.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

Figures 1 and 2 show an oil filter, which is an example of a liquid filter. In the figure, 1 is a transparent oil container made of heat-resistant synthetic resin, and one part of the upper edge of the container has a spout 1a. is formed in a bulging manner, and the peripheral wall 1b
A handle 1c is continuously provided on the outer surface.

Reference numeral 2 denotes a stainless steel filtration container, on the outer periphery of the bottom of which is formed an annular stepped portion 2a that is fitted into the upper edge of the oil container 1, and at the center of the bottom. The portion 2b is formed to bulge downward into a cylindrical shape, and a filtrate extraction port 2c is formed in the center of this bulged central portion 2b. Further, a receiving portion 2c for holding the stainless steel lid 3 in an internally fitted state is formed at the upper edge of the peripheral wall 2d.

Reference numeral 4 denotes a support member made of stainless steel on which the filter 5 can be placed and supported, and is configured in the shape of a disc with a slightly smaller diameter than the inner diameter of the bulging central portion 2b of the filtration container 2, and is shaped like a disc with a diameter slightly smaller than the inner diameter of the bulging central portion 2b of the filtration container 2. Holes 4a (which are an example of a flow path) that are substantially fan-shaped in plan view are formed at four equally spaced locations to guide the oil that has passed through the filter 5 down to the filtrate extraction port 2c.

Reference numeral 6 denotes a stainless steel handle connected to the center of the support member 4, and is sized to protrude above the filter 5 placed on the support member 4.

When the supporting member 4 and the handle 6 are placed in the bulging central portion 2b of the filtration container 2, a liquid-tight state is created between the lower surface of the supporting member 4 and the bottom wall of the bulging central portion 2b. It has a similar weight.

The filter 5 is constructed by winding a band-shaped filtering material such as filter paper or nonwoven fabric into a roll having the same or slightly smaller inner diameter than the bulging central portion 2b of the filtering container 2.

When used oil is put into the filtration container 2 of the oil filter constructed in this way, the oil slowly passes through the micron pores of the filter 5 and increases due to impurities in the oil and heating. oxides are filtered out. The oil filtered in a clean state is transferred to the support member 4.
The oil is stored in the oil container 1 through the hole 4a and the filtrate extraction port 2c.

If the filter 5 becomes clogged due to such oil filtration, by lifting the handle 6 that protrudes above the filter 5,
The entire used filter 5 can be taken out of the filtration container 2. Moreover, even when setting a new filter 5, the new filter 5 can be placed on the support member 4 in a wide space outside the filtration container 2.
Since it can be attached to the top, it can be set simply by lifting the handle 6 and dropping it into the bulging central portion 2b of the filtration container 2. Therefore,
This kind of replacement work for the filter 5 can be done quickly and easily while keeping hands from getting dirty as much as possible.

Next, another example will be described.

(B) In the above embodiment, four fan-shaped holes 4a were formed as the flow paths in the support member 4, but as shown in FIG. may be formed and implemented. In short, the flow path may have any shape as long as it can guide the liquid that has passed through the filter 5 down to the filtrate extraction port 2c.

(b) In the above-described embodiment, the annular bottom wall portion 2f at the bottom of the filtration container 2, which is connected to the outer periphery of the bulging central portion 2b, is configured horizontally, but as shown in FIG. 2f may be constructed in the shape of a funnel so as to be located below the center of the container.Furthermore, as shown in FIG. It may also be configured in a funnel shape, such that it is located at a lower position.

Further, as shown in FIG. 6, a rib 2g may be formed on the upper surface of the bottom wall of the bulging central portion 2b, and further, as shown in FIG. A sealing material 7 that elastically adheres to the inner circumferential surface of 2b may be fitted.

(c) In the above embodiment, a roll-shaped filter was used as the filter 5, but a stack of many plate-shaped filter materials may also be used, and a roll-shaped filter and a laminated filter may be used. may be used in combination.

Furthermore, a weight or an elastic presser may be used to hold the filter 5 toward the support member 4 side.
