Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a water purifier used for a bathtub or the like.

[0002]

2. Description of the Related Art As shown in FIG. 3, a conventional filter of this type is provided with a filter medium case 102 for storing a filter medium 101 and a filter medium cap 103, and pumps water in a bathtub 104.
There is a water purifier that decomposes and purifies organic matter in water by the microorganisms that are circulated by 05 and generated in the filter medium 101.

[0003]

However, in the above-mentioned conventional example, when the water purifier is used for a long time, a large amount of organic substances and microorganisms adhere to the filter medium 101, the flow becomes poor, and the water cannot be purified. Yes, in this case,
Cleaning by bubbling or cleaning by a stirring device was performed. However, cleaning by bubbling has the drawbacks of being time consuming and using a lot of water. In addition, there is also a drawback that washing cannot be performed when water has clogged due to clogging. On the other hand, the washing by the stirring device can be forcibly washed even if it is clogged, but the material and shape of the filter medium 101 are limited to ensure the durability, and the portion that the stirring device cannot reach cannot be washed. There is also a drawback. A common drawback is that the filter medium 1
Although 01 can be washed, it cannot remove the dust adhering to the pipe 107 and the pump 105. The cost is high because more parts and complex structures are required.

The present invention has been made in view of this point, and it is possible to wash with a small amount of water in a short time, and at the same time, it is possible to wash portions other than the filter medium, such as pipes and pumps, which have been impossible in the past. The purpose is to provide a water purifier.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. FIG. 1 is a cross-sectional view of a water purifier that is one embodiment of the present invention. As shown in FIG. 1, this water purifier comprises a filter medium case 2 for storing a filter medium 1, a filter medium cap 3, and a pump 4.
And a heater 5, and is connected to the bath 6 to purify the water in the bath 6. The ultrasonic oscillator 7 and its diaphragm 8 are attached to the outside of the lower surface of the filter medium case 2 of this water purifier, and the light emitting part 9 of the sensor for the ultrasonic oscillator 7 is provided in the middle of the piping between the filter medium case 2 and the pump 4. The light receiving unit 10 and the light receiving unit 10 are arranged so as to face each other, the transmitted light is detected, and the ultrasonic oscillator 7 is operated. The material of the filter medium 1 may be plastic or the like.

The method of using this water purifier will be described below. The water in the bathtub 6 is circulated by the pump 4, guided into the filter medium case 2, the organic matter in the water is decomposed and purified by the microorganisms generated in the filter medium 1, the temperature is kept warm by the heater 5, and the water is returned to the bathtub 6.

A light emitting portion 9 and a light receiving portion 10 of a sensor for the ultrasonic oscillator 7 are arranged so as to face each other in the middle of the piping between the filter medium case 2 and the pump 4, and the light emitted from the light emitting portion 9 is received oppositely. The unit 10 converts the signal into an electric signal, and the microcomputer constantly detects the transmittance of passing water. The light emitting unit 9 and the light receiving unit 10 of the sensor may be arranged inside the pipe or outside the pipe.

When the water permeability of the water purifier becomes longer than a certain value due to the dust adhered to the pipe due to long-term use, the microcomputer judges that it is time to clean the pipe, and the ultrasonic oscillator 7 is turned on. Activate. The ultrasonic vibration generated by the ultrasonic oscillator 7 vibrates the vibrating plate 8 and propagates through the water to every corner of the filter medium 1, the pipe, the heater 5 and the pump 4, and the dust on the surface of the filter medium 1 and the dust on the surface of the pipe. To remove. As a result, dirt on the filter medium 1, the pipe, the heater 5, and the pump 4 can be removed.
