DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid level purifying apparatus, for example, for storing hot water in a home or business bathtub to remove dust such as dirt, loose hair and lint floating on the water surface. Liquid level purification device.

[0002]

2. Description of the Related Art Hot water stored in a bathtub for home or business use is generally changed every other day or every two days. Dust is floating. Since it is not clean to use in a state where dust is floating in the bathtub, the bather removes the dust by using a basin or a net for dust removal before bathing. In order to eliminate the inconvenience of the person taking a bath to manually perform the dust removing operation before bathing, various types of electric liquid level dust removing devices have been proposed.

[0003] For example, as shown in Japanese Utility Model Publication No. 59-12980, a filter is provided at a liquid inlet opening parallel to the liquid surface and at a liquid outlet communicating with the liquid inlet through a fluid passage. There has been proposed a liquid-level debris removal device that applies a propulsion force to a floating body by a screw that is rotationally driven by a motor to generate a water flow from a liquid inlet to a liquid outlet to collect dust in a filter.
Further, as shown in Japanese Patent Application Laid-Open No. 8-182637, water near the water surface is sucked and sucked together with floating debris from a main body suction port opened below the liquid surface by a water flow generated by a screw connected to a motor. There has been proposed a liquid level debris removing device in which the collected water is captured by a filter provided in a flow path in the main body, and only the filtered water flows out.

[0004]

However, the liquid level debris removal apparatus disclosed in Japanese Utility Model Publication No. 59-12980 discloses a method for removing waste by injecting water from a liquid inflow port in parallel with the water surface. The inlet area needs to be wide along the water surface, and air is sucked together with the liquid near the water surface. Therefore, the water absorption efficiency is low, and the refuse once collected in the filter may flow out again. In addition, since the floating main body removes dust while propelling along the liquid surface, there is a disadvantage that the floating main body cannot move because it hits a corner of the bathtub. Further, the liquid level debris removal device disclosed in Japanese Patent Application Laid-Open No. 8-182637 can effectively remove dust near the water surface when the water surface is calm, but the water surface of the bathtub undulates when people enter and exit. When the air enters from the main body suction port and rises above the water surface because the main body of the device rises up and down, the main body of the device does not stand still and does not sink so that the main body suction port is below the water surface.
There is a problem that it becomes impossible to suck and remove water and dust near the water surface.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art, and has a high efficiency in removing dust floating on the liquid surface, and can reliably remove the floating dust even when the liquid surface is wavy. Is to provide.

[0006]

To solve the above-mentioned problems, the present invention has the following arrangement. That is, a cylindrical main body which is provided so that the upper end is always below the liquid level, and is provided so that the liquid flows in from the upper opening, passes through the filter and flows out from the lower opening, A notched portion into which a liquid can flow is formed, and a floating cylinder is fitted around the cylindrical main body so as to be vertically movable so that at least an upper opening end is exposed from the liquid surface. The cylindrical main body is provided so that the upper end is always below the liquid level, and the floating cylinder is fitted around the cylindrical main body such that the upper open end is exposed from the liquid level so as to be superimposed and balanced so as to be vertically movable. Therefore, even if the liquid surface undulates, it moves up and down following the liquid surface and the upper opening end always balances at a certain position with respect to the liquid surface. Since it can flow into the inside, is filtered by the filter of the cylindrical main body, and can flow out from the lower end opening, the stability of dust removal operation is high.

The cylindrical body may be floated so that the upper end is always below the liquid level by balancing the float provided on the upper part and the weight provided on the lower part. By restricting the inflow path of the liquid that is provided in the idler cylinder and flows into the idler cylinder from the notch, it is possible to prevent the dust removed to the filter by the reflux of the liquid from flowing out of the notch. Further, the cylindrical main body may be provided so as to be fixable to the liquid storage tank. This makes it possible to purify the liquid level particularly at a location that is easily contaminated, such as a 24-hour bath or a large public bath. In addition, when the cylindrical body has a built-in pump for flowing the liquid near the liquid surface and a drive source for driving the pump, it is convenient for portable use.
If the cylindrical body is provided with a timer that operates the drive source in a timed manner, it can be operated only during the entry and exit of people in the bathtub to purify the liquid level in the bathtub. Can be maintained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is an explanatory sectional view showing the entire configuration of the liquid level cleaning device. Reference numeral 1 denotes a liquid level cleaning device. In this embodiment, a case where the device is used while floating in a bathtub will be mainly described. Numeral 2 is a cylindrical body which floats in a direction perpendicular to the water surface, and the hot water near the water surface flows in from the upper opening 3 and passes through the filter 4 to the lower opening 5.
It is provided so as to flow out more. A pump 6 is built in the cylindrical main body 2, and the pump 6 is rotationally driven by a motor 6a as a driving source. As the motor 6a for driving the pump 6, for example, a small motor of about 20 VA is used. As a power supply for the motor 6a, a general commercial power supply is stepped down and used.

The cylindrical body 2 includes a first weight 7 provided together with a motor 6a for driving the pump 6, a filter 4
The first float 8 provided above is balanced so that the upper end 3a is always below the water surface. By disposing this tubular main body 2 in a direction perpendicular to the water surface, the filtered hot water flows out from the lower opening 5, so that the dust collected on the bottom side of the bathtub is also circulated to the upper part and removed. It is possible to do. The cylindrical body 2 and the first float 8 are preferably made of a relatively lightweight and water-resistant resin material. As the filter 4, a sponge material, a fine mesh resin material, or the like is used.

Reference numeral 9 denotes a floating cylinder fitted around the cylindrical main body 2 so as to be vertically movable. Notch portions 10 into which hot and cold water near the water surface can flow are formed at a plurality of places on the peripheral surface on the upper end side of the floating cylinder 9. In addition, a second float 11 is provided on the upper end side around the floating cylinder 9, and a second weight 12 is provided on the lower end side.
Floats in a superimposed balance around the cylindrical body 2 so that at least the upper open end 13 is exposed from the water surface. For example, in the present embodiment, the floating cylinder 9 is balanced so that the water level is half the water level in the height direction of the notch 10. Since the floating barrel 9 is balanced so that the upper open end 13 is slightly exposed from the water surface, when the water surface undulates, the floating barrel 9 also vibrates following the vibration of the water surface. Since hot and cold water flows into the floating cylinder 9, the cylindrical body 2
Is raised above the water surface, so that hot water near the water surface does not flow in and the pump 6 sucks air to reduce the efficiency, and the dust removal operation is highly stable.

A first float 8 provided on the side of the upper opening 3 of the cylindrical main body 2 is provided in the floating cylinder 9, and an upper portion of the float 8 is provided to be exposed from the water surface. ing. The first float 8 regulates an inflow path of hot water flowing from the notch 10 into the floating cylinder 9. Thus, it is possible to prevent the hot and cold water flowing into the floating cylinder 9 from circulating in the floating cylinder 9 and the dust removed from the filter 4 from flowing out of the notch 10 into the bathtub.

The range of movement of the floating cylinder 9 with respect to the cylindrical body 2 is such that the floating cylinder 9 does not come off from the cylindrical body 2 when the water surface undulates, and when air enters the cylindrical body 2. The cylindrical body 2 may be vertically movable within a range in which hot and cold water can flow again and return to a predetermined position.
It is sufficient that a stopper for retaining is provided on the outer periphery on the upper end side of. A resin material is suitably used as the floating cylinder 9, and a resin material, styrene foam,
Various things such as wood are used.

The method of using the liquid level cleaning device 1 will be described. When the liquid level cleaning device 1 is put into hot water collected in a home bathtub, the tubular main body 2 is placed below the water surface, and the floating cylinder 9 is placed at the upper open end. 13 is floated in a balanced manner so as to be exposed from the water surface. Then, a switch (not shown) is turned on and the motor 6 is turned on.
When the pump 6 is operated by activating a, the hot and cold water near the water surface flows into the floating cylinder 9 from the notch 10 and passes through the filter 4 attached to the upper opening 3 as shown by the arrow in FIG. The filtered hot and cold water from which the dust has been removed passes through the cylindrical main body 2 and flows out from the lower opening 5. A timer (not shown) for timed operation of the motor 6a is provided in the cylindrical main body 2.
May be provided. In this case, the cleaning of the liquid level in the bathtub can be achieved by operating the bathtub only while a person is in or out of the bathtub, so that a clean feeling in the bathtub can be maintained.

Although the above-described liquid level cleaning device 1 has been described as being used while floating near the water surface in a bathtub at home, it can also be applied to a large bath such as a hot spring. In this case, the suspended matter is usually removed by overflowing hot water from the edge of the bathtub, but there are portions where the suspended matter is difficult to remove, such as a central portion of the bathtub or a corner opposite to a portion where the overflow occurs. The first float 8 of the tubular main body 2 is omitted and fixed to the bottom of the bathtub at a place where the suspended matter easily accumulates. A floating cylinder 9 is fitted around the cylindrical main body 2 so as to be movable in the longitudinal direction. Notch portions 10 into which hot and cold water near the water surface can flow are formed at a plurality of locations on the upper peripheral surface of the floating cylinder 9. by this,
It is also possible to fix the liquid level cleaning device 1 to a part of a large bath or a bathtub of a 24-hour bath to purify the water surface.

Since the liquid level cleaning device 1 is equipped with the pump 6 and the motor 6a, if a hose is connected to the lower opening 5, the hot water after bathing can be sent to a washing machine or the like. And the added value of the product can be further increased. Further, in this embodiment, the pump 6 and the motor 6a are built in the tubular main body 2. When passing through the inside of the main body 2 or sending into the washing tub, it may be omitted.

The preferred embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and the liquid level cleaning apparatus 1 is not limited to use in a bathtub, and can purify the liquid level. It can be applied to various uses to achieve this.
For example, it can be applied to various purposes such as purification of liquid surface of pools, ponds, water tanks, etc., and removal of oil and dust floating in liquid storage tanks at factories and the like, and more without departing from the spirit of the invention. It is needless to say that the modification can be made.

[0017]

According to the liquid level purifying device of the present invention, the cylindrical body provided so that the upper end is always below the liquid level, and the superimposed balance around the cylindrical main body such that the upper open end is exposed from the liquid level. Since it has a floating cylinder fitted so that it can move up and down,
Even if the liquid surface undulates, the floating tube follows the liquid surface and moves around the cylindrical main body, and the upper open end is always balanced at a fixed position with respect to the liquid surface. The dust flows into the floating cylinder through the cutout portion together with the dust, and is filtered out by the filter of the cylindrical main body and flows out, so that the stability of the dust removing operation is high.
Also, the cylindrical body may be floated so that the upper end is always below the liquid level by balancing the float provided at the upper part and the weight provided at the lower part, in which case the float floats from the notch. By restricting the inflow path of the liquid that has flowed into the cylinder, it is possible to prevent the liquid that has flowed into the idle cylinder from circulating and the dust removed by the filter from flowing out of the notch. Further, the cylindrical main body may be provided so as to be fixable to the liquid storage tank, whereby it is possible to purify the water surface particularly in a dirty place such as a bath or a large bath for 24 hours. In addition, when a pump for flowing liquid near the liquid surface and a drive source for driving the pump are built in the tubular body, the portable body is convenient for use, and the operation of the drive source for driving the pump in the tubular body is convenient. When a timer is provided for operating the timer in a timed manner, the liquid level of the bathtub can be purified by operating the bathtub only while a person is in or out, so that a clean feeling in the bathtub can be maintained.
