Description

The present invention relates to drainage of water tanks and bathtubs.

Liquids, water, hot water, etc. (hereinafter referred to as “water”) stored in various aquariums including bathtubs (hereinafter referred to as “bathtubs”) are subject to various “dirt” and “impurities” depending on the use of the water. , "Floating matter" etc. are mixed.

Taking bathing as an example, even if the water in the bathtub is dirty due to bathing, in many cases, there are many households where the hot water in the bathtub is not replaced while several family members bathe, but at this time the water in the bathtub is less dirty If this dirt can be removed efficiently, it can be linked to an environment-friendly life, such as improving hygiene during bathing and making it easier to use the remaining hot water for washing.

Among them, dirt components floating on the water surface (hereinafter referred to as “floating matter”) are very easy to see due to the nature of floating on the water surface. Many things are commercially available, such as a device that attaches to a drain outlet as in Patent Document 1 and drains the water near the suspended substance, and a filter device that has a built-in pipe in the bathtub as in Patent Document 2 has been invented. .

Patent Publication No. 2009-171991 Patent Publication 2000-342473 JP 10-33916 A Japanese Patent Application No. 11-256096 Utility model registration No. 3154760 JP 2008-73120 A

The float removing device that crawls suspended matter with a net as in Patent Document 3 has a high effect on hair and the like. However, oil such as sebum passes through the mesh and passes through water. Depending on the quality of the dirt, it is often ineffective.

Moreover, the method which attaches an instrument to a drain outlet like patent document 5 and patent document 6, and discharges the floating substance in a bathtub from the drain outlet of a bathtub draws in a floating substance by drainage of the water of a bathtub, and is very effective. Although it can be expected, since it is difficult to attach and detach the equipment when it is full, it is difficult to attach and detach the equipment when it is full. There is also a danger of getting in the way, or in the worst case, getting caught off and draining a large amount of water.

Moreover, there is a high possibility that a large amount of water will be drained unintentionally when it is forcibly attached and detached with water in the bathtub.

Although the method of adding overflow to the bathtub itself and performing overflow drainage as in Patent Document 4 is very effective for removing floating substances, in order to drain water, water supply to the bathtub is required. For example, If the last bather or the like is taking a bath and wants to remove suspended solids when he / she does not want to add extra hot water, the unnecessary additional hot water to make overflow water is uneconomical, The introduction of this apparatus requires work on a scale such as a bathtub exchange, and is difficult to realize easily.

To drain the hot water near the surface of the water, as in Patent Document 6, float the water intake near the surface of the water with a buoyant part (hereinafter referred to as “float”) such as floating the water intake to drain the water. A method of adjusting the intake to be slightly below the surface of the water can be considered, but the problem is that when the intake with the float attached follows the surface of the water, it will drain to the intake with the float. This requires a structure that keeps the pipe following the intake.

In Patent Document 6, a bellows tube that can expand and contract is used in order for the tube to follow the water surface. However, the bellows-shaped tube excellent in elasticity that can sufficiently follow the water surface that rises and falls is thin with a fairly flexible material. If it is not a structure, it is difficult to make a structure with excellent followability, and if a thin material is used, the expansion and contraction performance is likely to decrease due to slight deterioration, and the water surface may not be able to follow with slight deterioration. Get higher.

Another disadvantage is that the flexible bellows between the bellows is not affected by the flow of water, such as a large deflection of the bellows tube caused by the slight flow of water. there is a possibility.

The telescopic type using two cylinders of different thickness, which was devised in Patent Document 5, cannot adjust the water surface automatically because the length is adjusted manually in this device. A structure that can automatically follow the water surface, such as a telescopic suspension of a motorcycle, is also conceivable. However, with this method, even if the joint part of the two cylinders can be smoothly expanded and contracted by sliding, scales or sebum immediately adheres to the slide part, causing resistance to expansion and contraction and continuing to follow the water surface for a long time. There is a high possibility of not being able to.

Therefore, the present invention has a structure capable of long-time operation without causing modification or replacement of the bathtub, and preventing the apparatus from being stopped due to dirt during use, and the bellows in the bathtub is liable to deteriorate. An object of the present invention is an apparatus that drains water in the vicinity of a water surface by following a water surface by a mechanism that uses a structure other than a slide expansion / contraction type water surface tracking method that is easily affected by dirt.

Moreover, the drainage device which attached the water level adjustment drainage device to the water level adjustment drainage device connection part of this drainage device

According to the invention of claim 1, the water intake portion having buoyancy due to the float can be kept floating near the surface of the water due to the flexible deformation of the falling water pipe, thereby allowing drainage and other reasons. Even if there is a change in the water surface position, the water intake section that follows the water surface can drain water in the vicinity of the water surface into the pipe of the water falling section.

When water entered from the intake section flows into the falling water section and exceeds the reference water level of the falling water section set in the drainage apparatus falling section, the water is drained by the water level adjusting drainage device through the pumping drainage pipe.

Since the water level in the device is constant and the head can be maintained at a constant level with the intake, the water flowing into the intake does not flow back to the bathtub.

It is the figure which wrote FIG. 18 with another form It is a figure of the structure which can discharge water to a position higher than a water surface.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In the drainage device shown in FIG. 1, water near the water surface taken in by the water intake unit 11 that floats on the water surface 2 with the float 19 falls from the water intake unit drain port 21 to the water drop unit 12 and accumulates in advance. The amount of water exceeding the in-device water level 18 set by is discharged from the water level adjusting drain device drain port 16 by the water level adjusting drain device 15.

The water intake section shown in FIG. 2 operates in a state where it floats on the water surface 2 by a float 19 drawn by a broken line.

At this time, the water intake 24 is provided with a water intake portion water level difference 20 from the water surface 2, and the water taken in from the water intake 24 flows out from the water intake portion drain outlet 21.

In the state when the amount of hot water in the bathtub shown in FIG. 3 is large, the water intake portion hanging stopper 17 fixed to the intake portion 11 and the pumping portion is loosened, but the amount of hot water in the bathtub decreases as shown in FIG. And the water intake part 11 maintains the position with respect to the water surface 2 by the water surface following by the buoyancy of the float 19, and the water falling part 12 follows the movement of the water intake part 11 by the deformation | transformation of the raw material.

And it can prevent draining until hot water runs out by stopping the water intake part 11 from following the water surface 2 by stopping the water intake part 11 by having the water intake part suspension stopper 17 in a stretched state. .

The water intake section 11 and the float 19 shown in the drawings from FIG. 5 to FIG. 8 are prepared in an easy-to-understand shape for the explanation of this principle. If the operation principle is the same, the actual shape is this shape. I don't need it.

In the drainage device shown in FIG. 9, in the drainage device of Example 1, the water flow of the pumping unit 13 becomes unstable due to the position of the water intake unit 11, the position of the water level adjustment drainage device 15, and the structure of the water level adjustment drainage device 15. If the mounting condition is bad, there is a possibility of causing a back flow in the apparatus.

On the other hand, by providing a check valve for the pumping unit 13 and other flowing water paths, the flow of water can be stabilized and the backflow of water can be prevented.

The drainage device shown in FIG. 10 is a method of using the water level adjustment drainage device water tray 29 for the structure of the water level adjustment drainage device 15.

This water level adjustment drainage is based on the principle of siphon by making the outlet on the drainage side of the pipe connected to the drainage connection pipe 14 below the position where the water level in the water receiving tray 29 for the water level adjustment drainage device is full. The water level of the apparatus water tray 29 becomes the in-apparatus water level 18, the drainage in the bathtub operates, and the water that has passed through the water level adjustment drain apparatus water tray 29 flows down and is drained.

The drainage device shown in FIG. 11 is a method of using the structure of the water level adjusting drainage device 15 with the check valve 54 attached to the check valve mounting portion 53.

In the method using a check valve, when the water level is higher than the water level 18 in the apparatus of the falling water part 12 due to the principle of siphon, water pressure is applied to the check valve and the check valve is opened and drained. When the water level is lower than 18, the water pressure is negative with respect to the check valve, and water is not discharged.

FIG. 12 is an expanded view of the check valve portion of FIG.

The drainage device shown in FIG. 13 uses a trap type water level adjustment drainage device 55 as the structure of the water level adjustment drainage device 15.

When there is water up to the trap drain of the trap type water level adjusting and draining device 55, the water level of the drain port of the trap type water level adjusting and draining device 55 becomes the water level 18 in the device from the principle of siphon, and the drainage in the bathtub operates. To do.

The drainage device shown in FIG. 14 has a function equivalent to that of a siphon type pump that is generally used in the transfer of petroleum, which is generally marketed, in the structure of the drainage device of FIG. When starting the operation of the drainage device that operates with the siphon principle such as 5, the pump can be used to start the siphon operation, and the pumping unit is filled with water. Usability can be improved.

The drainage device shown in FIG. 15 is the drainage device of Example 1, and can be easily removed from the bathtub and stopped when the drainage is unnecessary.

At that time, the minimum position of the water intake section 11 is maintained above the position of the water level 18 in the apparatus by the water intake section suspension stopper 17, and the water in the pumping section 13 is obtained by both the effects of the water level adjusting and draining apparatus 15. When the drainage device is set again in the bathtub as shown in FIG. 16, there is a merit that the operation of the siphon principle starts automatically without performing any operation.

The figure shown in FIG. 17 shows an example of the water level adjusting drainage device 15 using an on / off valve by an electrically controlled switching device as an example of the water level adjusting drainage device 15 of the present invention.

The figure shown in FIG. 18 shows the example of the water level adjustment drainage apparatus 15 using the drainage control by the motor-type water pump 74 of electric control as one example of the water level adjustment drainage apparatus 15 of this invention.

The operation flow chart shown in FIG. 19 is an example of the operation flow of drainage control when using the electrically controlled water level adjusting drainage device 15 as in the eighth and ninth embodiments.

There are devices that have been invented in the past and that can drain water from the surface together with suspended matter that collects on the surface of the bathtub. There is a problem that it is difficult to attach or detach when the bathtub is filled with water, such as when bathing, or if there is a risk of unintentionally draining a lot of water in the bathtub if Difficult. In addition, in a scooping device that scoops floating matter with a net, hair etc. are prepared to be removed, but the fat may pass through the net and is less effective.

Therefore, an apparatus for draining water taken from the vicinity of the water surface by following the surface of the water with a float is provided. By following the water surface using the deflection of the pipe used in the device, the degree of freedom of the material and shape of the piping that follows the water surface is increased. In addition, by providing a water intake stopper, drainage can be stopped when the water level falls below any water level in the water tank. Moreover, even if drainage stops when the device is removed from the bathtub, the water in the device is retained, and drainage starts when the device is attached to the bathtub again.

The drainage apparatus shown in the other embodiments including the drainage apparatus shown in FIG. 1 can be used not only in a bathtub but also in various water tanks.

For example, in the drainage device shown in FIG. 20 that is substantially equivalent to FIG. 1 described in the embodiment, when the wastewater and floats on the surface are removed by using the drainage device in FIG. The water in the vicinity of the water surface taken in by the water intake part 11 floating on the water surface 2 in 19 falls from the water intake part drain port 21 to the water drop part 12 and accumulates. As for the amount of water exceeding the water level, the operation of being discharged from the water level adjustment drainage device outlet 16 by the water level adjustment drainage device 15 is the same as in the case of the bathtub, and the floating matter on the water surface can be discharged together with the drainage.

The drainage device shown in FIG. 21 can also be used for natural or artificially created water reservoirs such as ponds and swamps, and large water surfaces such as ponds.

As the water level adjusting and draining device 15, a device capable of forcible drainage using an electric motor or a water pump is suitable.

In addition, the water level adjustment of the water level adjustment drainage device 15 is a method of determining by measuring water pressure or the like, or a method of using a float switch and disposing only the float switch at a position below the surface of the water to be set as the in-device water level 18. However, it does not specify a specific method.

In FIG. 21, the latter method using the float switch is used. However, with this method, it is possible to easily collect floating matters having a fine water surface or oil flowing in.

The present plan relates to a water tank, a pool, a bathtub, and the like that can be used as a device used when draining water or liquid.
