[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath water circulation purifying apparatus, in which noise that is a driving sound of a circulation means (circulation pump) for circulating bath water and a driving means (motor) for driving the circulation means is referred to as the noise. The present invention relates to a bath water circulating device having a silent function that can emit a canceling sound of an opposite component from a speaker to reduce the noise.

[0002]

2. Description of the Related Art A bath water circulating purifying apparatus has been proposed which circulates bath water to purify and sterilize it and to keep it warm by heating.
This equipment uses a circulation pump to circulate the bath water,
It is driven for 4 hours, so that it can be driven in the middle of the night when there are no people.
Occasionally, the driving noise could make noise and interfere with the sleep of residents.

[0003]

However, if the operation is stopped in order to eliminate the operation noise at midnight, the essential functions of cleaning and sterilizing the bath water cannot be performed, and there is the inconvenience that the device is meaningless. It was Therefore, there is a demand for a bath water circulating device that can reduce noise.

[0004]

Therefore, as a result of intensive studies, the inventor of the present invention has found that the present invention can be applied to a bath water circulating apparatus for cleaning bath water in a bathtub.
Circulating means for circulating the bath water, driving means for driving the circulating means, cleaning means for cleaning the bath water, sterilizing treatment means for sterilizing the bath water with ultraviolet rays, and the circulating means and driving means. A canceling noise storing means for storing noise data of a canceling component for canceling the waveform of the driving noise, and a canceling noise generating means for generating noise of the canceling component based on the noise data stored by the canceling noise storing means. By this, the noise that is the operating sound of the circulation means (circulation pump) and the driving means (motor) can be silenced by releasing the cancellation sound of the component opposite to the noise from the speaker. Has been achieved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, in a schematic block diagram of the present invention, the inner wall of the bathroom where the bathtub 1 is provided or the bathroom side portion is
A warm water heat retention purification device A is provided. The hot water heat retention purification apparatus A is specifically composed of a circulation means 2, a driving means 3, a heating means 4, a cleaning means 5, a sterilization processing means 6 and the like.

The circulation means 2 is constructed as a circulation pump for circulating bath water. The driving means 3 is a motor for driving the circulation means 2, and the heating means 4 is an electric heater.

The cleaning means 5 serves as a filter for cleaning the bath water, and the sterilization processing means 6 uses ultraviolet rays to sterilize the bath water.

A prefilter 7 for removing dirt from the bath water is also provided, and the prefilter 7, circulation means 2 and heating means 4 are provided.
A circulation pipe 8 is provided between the cleaning pipe 5 and the cleaning means 5, and both ends of the circulation pipe 8 are arranged in the bath 1.

The configuration of the control section B controlled by the computer is as shown in FIG. 2, and mainly, the canceling for storing the noise data of the canceling component for canceling the waveforms of the driving sounds of the circulating means 2 and the driving means 3 is canceled. It comprises noise storage means 9 and cancellation noise generation means 10 for generating noise of a cancellation component based on the noise data stored by the cancellation noise storage means 9.

Cancellation noise storage means (ROM)
Reference numeral 9 is provided so as to generate sound data of a canceling component that cancels the driving noise in response to the driving noise generated at a predetermined rotation speed of the circulation unit 2 and the driving unit 3.

The cancellation noise storage means 9 and the cancellation noise generation means 10 are a central processing unit (CPU).
The canceling noise generating means 10 is connected to 20 and is configured as a speaker.

Further, the normal / silent mode switching means 11 is connected to the central processing unit (CPU) 20, and when this is selected, the cancel noise storage means 9 and the cancel noise generating means 10 operate. It is configured.

The temperature comparison means 12 uses the temperature detection means 15 which is a temperature sensor for storing the hot water temperature set by the temperature setting means 13 in the set temperature storage means 14 and the hot water temperature in the bathtub 1. It is determined whether the measured temperature is higher or lower, the data is transferred to the central processing unit 20, and the temperature is displayed on the display means 16. In particular,
When it is low, it is heated by the heating means 4, and when it is high, it is cooled by the water supply means 17. Also,
The sterilization processing means 6 is provided with sterilization control means 18,
It is connected to the central processing unit (CPU) 20.

Next, the action of the operation will be described with reference to the flow chart of FIG. 3. The bath water is filled in the bathtub 1 to bring it into an appropriate hot water state, and the circulation means (circulation pump) 2
Then, the driving means (motor) 3 turns on the operation of the warm water heat retention purification device A (see S1). At this time, in the state where the warm water insulation purifying apparatus A is operating, if the normal / silent mode switching means 11 is not selected, the normal mode operation is performed (see S2), and the circulation means 2 and the driving means 3 are operated. The driving sound of is generated. Then, when the silent mode is selected by the normal / silent mode switching means 11 (see S3), the silent mode operation is performed, and the cancel noise storing the noise data of the cancel component for canceling the waveform of the operating sound of the circulation means 2 and the driving means 3 is stored. The noise control data stored in the storage unit 9 is read out, and the noise of the canceling component is output from the cancel noise generating unit 10 based on the noise control data (see S4).
Then, the rotation noises of the circulation means (circulation pump) 2 and the drive means (motor) 3 and the cancel noises cancel each other, and the sound wave can be erased from the operating portion of the hot water heat retention purification device A. When the normal / silent mode switching means 11 is switched to select the normal mode, the silent mode ends (see S5). Then, the operation of the warm water heat retention purification device A is turned off and the operation is terminated (see S6).

Note that the noise control data may store cancel noise data preset by noise analysis, and the level thereof may be adjustable. Further, as the canceling noise, it is also effective to make it possible to select a canceling noise that is configured to cancel and emphasize only the unpleasant frequency component.
