Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underwater filter for filtering hot water in a bathtub by immersing it in the bottom of the bathtub.

[0002]

2. Description of the Related Art As a conventional submersible filter, the inside of the casing is partitioned into an upper filtration chamber provided with a filtering member and a lower reflux chamber into which hot water passing through the filtering member is guided, and an upper peripheral surface of the casing. The hot water taken into the upper filtration chamber from the water absorption hole formed in the upper part is purified while being passed through the filter member and guided to the lower recirculation chamber, and is discharged to the surroundings from the discharge hole formed in the lower peripheral surface of the casing to be refluxed. However, for example
It is described in JP-A-2-42733.

[0003]

However, in the case of the above-mentioned conventional submersible filter, when the user does not use the submersible filter, it is necessary to pull it up from the water by using the handle provided on the upper surface of the filter as a clue. It is troublesome because it is necessary to insert a hand inside and reach the handle member that is submerged near the bottom of the bathtub. Especially in winter, it is a tough task for housewives, because they have to put their sleeves in and put their bare hands in cold water.

Further, since the handle is provided on the upper surface of the submersible filter, when the operation is stopped and the container is pulled up from the bathtub or the like without changing its operation, it is in the upper filtration chamber and has not been processed yet. There is a disadvantage that hot water flows back from the water absorption holes on the upper peripheral surface of the casing, and at that time, dirt and hair adhering to the surface of the filtering member flows down into the bathtub again, thereby contaminating the bathtub.

Therefore, the present invention improves the convenience of stopping the operation and pulling it up from the bathtub or the like, and further, there is a possibility that untreated hot water and dirt in the filter may flow back and be returned to the bathtub when pulling up. Aims to provide no submersible filter.

[0006]

SUMMARY OF THE INVENTION The present invention has been proposed to achieve the above object. What is stated in claim 1 is:
It can be operated in a state where it is submerged in a bathtub, and a pump and a filtering member are provided inside the casing, hot water is taken into the inside from a water absorption hole formed on one side, and the hot water is filtered through the filtering member. After that, in the submersible filter which discharges from the discharge hole formed on the other surface except the one side surface where the water absorption hole is formed and recirculates back into the bath, both surfaces adjacent to the one side surface where the water absorption hole is formed. The one base end and the other base end are rotatably fixed to each other, and the arch portion between the both base ends is pivotable to the one side surface side, and one end is connected to the grip member. , And an operation member having a float at the other end.

Even if the submersible filter is immersed in the bathtub and used,
The float of the operating member remains floating on the surface of the hot water in the bathtub. Therefore, when stopping the use and pulling up the submersible filter, first, the float floating on the water surface is picked up, and then the operating member is pulled up, so that the handle member connected to one end of the operating member is pulled. The arch part begins to rise while turning around the fastening base end. When the operating member is further pulled up, the proximal end of the handle member pulls up the water absorption hole side of the submersible filter, so the submersible filter gradually swivels so that the one side where the water absorption hole is formed is the upper side, and When the operation member is pulled up, the submersible filter is suspended with the water absorption hole facing upward. When the operating member is further raised in this state, the submersible filter is pulled up to the water surface. Then, when the filter is further pulled up, the untreated hot water in the filter cannot flow out from the water absorption holes on the upper surface, and therefore flows down in the filter member and is filtered. Therefore, it is possible to prevent untreated hot water from flowing back into the bath as it is. Further, since the untreated hot water does not flow back from the water suction holes, it is possible to prevent dirt such as dirt and hair attached to the filter member from flowing back into the bath.

According to a second aspect of the present invention, one side face having a water absorption hole is made openable and closable, a filtration chamber is formed inside the one side face, and a filtration cartridge is detachably mounted in the filtration chamber, The filtration cartridge is one in which a filtration material is arranged in the order of a physical filtration layer, a microbial filtration layer, and a physical filtration layer from the side closer to the water absorption holes.

When the hot and cold water taken in from the water suction holes passes through the filtration cartridge, it first passes through the physical filtration layer to physically remove dirt such as dirt and hair, and the next microbial filtration layer. When passing through, the fine organic dirt is eaten by the microorganisms and removed, and then the remaining physical dirt is removed by passing through the physical filtration layer.
Therefore, the hot water is surely purified by passing through the filtration cartridge.

When hot and cold water is filtered and purified, the removed contaminants are gradually deposited on the filtration cartridge and the filtration capacity is lowered. So, if you open one side with water absorption holes,
Since the filtration cartridge can be removed, it can be easily replaced with a new filtration cartridge.

According to a third aspect of the present invention, the fixing position of the handle member with respect to the casing is set on the water absorption hole side with respect to the center of gravity position.

When the handle member is lifted by stroking the operating member, and the fastening position of the handle member with respect to the casing is located on the water absorption hole side with respect to the center of gravity position, one side face where the water absorption hole is formed surely moves upward. Turn to.

The lid plate 12 is not limited to the one that slides toward the fastening base end 10 ′ side of the handle member 10, and may be openable / closable by a hinge mechanism or may slide below the casing 5. You may comprise. In any case, it is desirable to provide a stopper that maintains the closed state of the cover plate 12.

An operation member 1 having one end connected to the handle member 10.
No. 1 has a float 35 provided at the other end of a flexible elongated member 34 such as a string, a chain, or a rope. Then, the length of the operation member 11 can be appropriately set in consideration of the depth of the bathtub 2. That is, the submersible filter 1
The length at which the float 35 floats on the surface of the hot and cold water in a state where the float 35 is placed on the bottom of the bathtub 2 may be appropriately set. In addition, when one end of the operation member 11 is connected to the handle member 10, the operation member 11 may be directly connected, but as shown in the drawing, the connection is improved via the ring member 36 to improve the appearance.

When using the submersible filter 1 having the above-described structure, the submersible filter 1 is placed on the bottom of the bath 2 as shown in FIG. It is desirable that the handle member 10 be tilted down during use. When the submersible pump 9 is activated in this state, the hot and cold water in the bathtub 2 is taken into the filtration chamber 6 through the water suction holes 3 and is filtered by passing through the filtration material in the filtration cartridge 7. That is, first, hair and large dust are removed when passing through the physical filtration layer of the first chamber 28, and then fine dust and the like are converted into microorganisms when passing through the biological filtration layer of the second chamber 29. It is eaten and removed, and then the fine dirt left behind when passing through the physical filtration layer of the third chamber 30 is removed.

The hot and cold water thus filtered is collected in the water collecting chamber 17
Pumped from the suction port 19 of the submersible pump 9
The purified hot water sucked in and discharged from the discharge port 21 is recirculated from the discharge hole 4 into the bath 2. Therefore, since the hot and cold water in the bathtub 2 is purified by passing through the submersible filter 1 installed in the bathtub 2 and does not flow out of the bathtub 2, there is no risk of the temperature lowering. Therefore, it is not necessary to provide a heater.

When the submersible filter 1 is pulled out of the hot and cold water after the use is stopped, the float-shaped float 35 floating on the surface of the hot and cold water is used as a mark to operate the string-like operation member 11 (the long member 3).
4) Pull up by hand. When the operating member 11 is pulled, the handle member 10 gradually begins to turn in the direction of raising the arch portion 32 as shown by a chain line in FIG. 3, and when the operating member 11 is further pulled, the handle member 10 becomes almost vertical. When standing up and continuing to pull the operation member 11 further, as shown in FIG. 3, the submersible filter 1 rises with one side having the water absorption holes 3 facing upward, and finally the one side. Is hung with the upper side facing up.

When the operating member 11 is further pulled up in this state, the submersible filter 1 can be gradually pulled up, and if the handle member 10 is pulled up to near the water surface, as shown by the chain line in FIG. The handle member 10 can be held and pulled up from the bathtub 2. At the time of this pulling up, the hot and cold water in the submersible filter 1 cannot flow back into the bathtub 2 from the water absorption holes 3 because the water absorption holes 3 face upward, and after being filtered through the filtering member, the submersible pump When it is pulled up, it flows back into the bathtub 2 through the discharge hole 4 which is laterally oriented.

Therefore, it is not necessary for the user to pull up the submersible filter 1 by inserting the arm to the bottom of the bathtub 2 when pulling up, and convenience is improved. Also, the submersible filter 1
When pulling up, the hot water in the interior that is not filtered and the dirt and hair adhering to the surface of the filter member do not flow back into the bathtub 2, which is preferable from a hygienic point of view and the bathtub 2 does not become dirty. The cleaning work of 2 is also easy.

In the above-mentioned embodiment, in order to ensure the purification of the hot water, the filter member is arranged in the order of the physical filter layer, the microbial filter layer and the physical filter layer from the side closer to the water absorption hole 3. In order to improve the convenience of replacement, the filtration member is loaded in a single filtration cartridge 7. However, the design, arrangement, material, etc. of the filtration member in the present invention may be changed as appropriate. However, the present invention is not limited to the above embodiment.

[0027]

As described above, according to the present invention, even when the submersible filter is submerged in the bathtub and used, the float of the operating member remains floating on the surface of the hot and cold water in the bathtub, and therefore the use is stopped. When pulling up the submersible filter by pulling the operating member with the float as a clue, the submersible filter can be pulled up without inserting the hand to the bottom of the bathtub. Therefore, the pulling operation of the submersible filter can be performed very easily, and it is not necessary to wind up the sleeve.

When pulling up the submersible filter, untreated hot water in the filter does not flow out from the water absorption holes on the upper surface, so untreated hot water and dirt such as dirt and hair adhering to the surface of the filtering member remain in the bathtub. It is possible to prevent the reflux. Therefore, it is preferable from the viewpoint of hygiene, and since dirt is not left in the bathtub, cleaning work of the bathtub is easy.

According to the second aspect of the invention, since the filtration member in which the physical filtration layer, the microbial filtration layer and the physical filtration layer are arranged in this order is housed in a single filtration cartridge, the filtration member is When exchanging, the filtration cartridge unit can be used. Therefore, the handling and the replacement work of the filtering member can be easily performed.

Further, in the invention according to claim 3, since the fixing position of the handle member to the casing is set to the water absorption hole side with respect to the position of the center of gravity of the submersible filter, the handle member can be pulled by hand. When you lift up, one side with the water-absorbing holes should face upward surely.
