Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bathtub device, and more particularly to a bathtub hot water purifying device that purifies hot water by a filtration tank filled with a filter medium such as activated stone or activated carbon.

[0002]

[Prior art]

 Recently, there is a bathtub hot water purification device that pumps hot water in a bathtub with a circulation pump and forcibly circulates it through a circulation path equipped with various types of cleaning treatment equipment, and ejects the purified hot water into the bathtub again. It has been developed.

An example of this bathtub cleaning device is as shown in FIG. 3, and a circulation pump is provided through a hot water pipe 3 equipped with a prefilter 4 for removing large dirt at the tip of the bathwater 2 in the bathtub 1. It is pumped up at 5, treated in a filtration tank 6 loaded with a filter medium 7, and then returned to the bath 1 from the spout tube 9.

In this case, the filtration tank 7 is provided with a heater 8 for keeping the hot water at an appropriate temperature, and a jet nozzle 10 is attached to the tip of the spout tube 9 so that the hot water is blown out as a jet flow together with the drawn air. You can enjoy the bath.

Further, in order to sterilize the hot water with the air sucked by the jet nozzle 10, the jet nozzle 10 is connected to an ozone pipe 13 for sending air obtained by ozone-izing the air sucked by the intake pipe 11 by the ozonizer 12.

[0006] With the thus configured cleaning device, the dirt in the hot water is removed and sterilized at the same time. Furthermore, the temperature of the hot water is constantly maintained at an appropriate temperature so that the hot water can be enjoyed as a bubble bath 24 hours a day. Has become.

The filter medium 7 loaded in the filtration tank 6 is various natural or artificial granular filter medium such as activated carbon, zeolite, and barite stone, and these form a single or a plurality of filter layers.

As a result, the filtration tank 6 has a filter material that not only removes dirt by the filtering effect of the filter layer but also removes dirt components by ion exchange or adsorption or elutes the mineral having a warm bath effect. Water treatment according to the ability is also performed, and it is effective in cleaning the bath water.

In such a cleaning device, when the operation is continued, the filter medium filled in the filter tank becomes dirty and the filter layer is clogged, the circulating amount of hot water is reduced, and the cleaning ability is deteriorated. .

For this reason, when the filter layer is clogged, the filter medium forming the filter layer is not always cheap and cannot be frequently replaced. Therefore, the filter medium is taken out of the filtration tank and washed.

Further, since cleaning the filter medium is time-consuming and is not preferred for dirty work, it is necessary to clean the filter layer with hot water so that the filter medium can be automatically cleaned without removing the filter medium from the filter tank. Many devices have been developed that are equipped with a so-called backwashing device for washing the filter medium by flowing it in the direction opposite to that for automatic washing.

[0012]

[Problems to be solved by the device]

 However, in the conventional washing using a backwashing device, the pressure of the hot water flowing back is not so strong that the layers of the filter media do not collapse even when the hot water flows and the filter media are in close contact with each other. Dirt could not be removed very well.

[0013] Therefore, various attempts have been made to apply ultrasonic vibrations to the filter medium to destroy the layer of the filter medium to improve the cleaning effect even a little. However, since the filter medium particles are relatively large and heavy, the filter medium is relatively large. It was difficult to break up the layers of the torn pieces by vibration.

In addition, the device for applying vibration to the layer of the filter medium is complicated and expensive, and at the same time, it is easy to break down, and maintenance of the device is difficult.

The present invention solves the above-mentioned drawbacks of the prior art, and provides an inexpensive apparatus for cleaning bathtub hot water that can easily and efficiently wash the filter medium without using a special device for washing. It is intended to be provided.

[0016]

[Means for Solving the Problems]

 That is, the present invention is that the hot water in the bathtub is pumped up by the circulation pump through the hot water pipe, the dirt is filtered by the filtration tank filled with the filter medium, and then returned to the bathtub through the hot water pipe to keep the hot water constantly clean. In the apparatus for cleaning hot water in a bathtub, a cleaning device for hot water in a bathtub is characterized in that the filtration tank is formed by removably mounting a filtering material bucket having a cleaning hole on a side surface thereof with a filtering material. is there.

[0017]

[Function of the device]

 The present invention is configured as described above, and when cleaning the filter medium, first remove the filter medium bucket from the inside of the filtration tank, remove the lid of the cleaning hole, and then fit the tip of the hose connected to the tap into the cleaning hole. , Wash the filter medium by running tap water vigorously.

When the filter medium is washed in this way, the layer of the filter medium in contact with the water flow collapses and the dirt is well removed, and it is difficult to clean the whole with one cleaning hole. The cleaning holes are provided and the cleaning hose to which the cleaning hose is fitted is changed one after another for cleaning, or the cleaning hose is fitted to each of the plurality of cleaning holes and the cleaning water is simultaneously supplied to the plurality of cleaning holes. If you let it flow, you can easily clean the whole.

In this way, the filter medium can be easily washed without directly touching it, and since no special device is used for washing, the cost of the cleaning device does not increase.
