The piezoelectric sensor can detect the noise of the water heater 1 and convert the noise into a current signal; the noise generator 6 is used for generating sound waves with the opposite frequency to the noise of the water heater 1 according to the current signal so as to counteract the noise of the water heater 1.
The water heater 1 detects and collects noise through the noise detection device 5, and actively generates sound waves with opposite frequency to the noise of the water heater 1 according to the detected noise through the noise generator 6, so that active noise reduction of the water heater 1 is realized. The noise detection device 5 is electrically connected to the noise generator 6, whereby automatic noise reduction can be achieved. The noise detection devices 5 are electrically connected with the operators 4, so that a user can conveniently control the detection mode, parameter setting and the like of the noise detection devices 5 through the operators 4 (for example, setting the minimum noise value detected by the noise detection devices 5), detect noise according to actual needs, and improve the active noise reduction effect. The noise detection device 5 is integrated on the manipulator 4, so that the circuit design of the two (the noise detection device 5 and the manipulator 4) for realizing electric connection is simplified, the cost is low, the space occupied by parts is saved, and the operation is convenient.
In other embodiments, the number of the noise detection devices 5 and the number of the noise generators 6 can be adjusted accordingly as required, that is, a plurality of noise detection devices 5 can be arranged at different positions, and accordingly, a plurality of noise generators 6 can be additionally arranged to fulfill the aim of reducing noise of noise sources at different positions. When there are a plurality of noise detection devices 5, all the noise detection devices 5 may be integrated on the operator 4, or part of the noise detection devices 5 may be integrated on the operator 4, and other parts of the noise detection devices 5 are independently disposed at other positions of the water heater 1, and are electrically connected to the operator 4 through separate wired connections.
As shown in fig. 1, the case 2 is provided with an air inlet 20, the operator 4 is provided at a position of the case 2 near the air inlet 20, and the noise detection device 5 is provided in the case 2.
The manipulator 4 is arranged at the position of the box body 2 close to the air inlet 20, the distance from the integrated noise detection device 5 to the air inlet 20 is shortened, larger noise generated at the air inlet 20 is effectively collected, and detection errors are reduced.

Specifically, the noise generator 6 is integrated on the control unit 7, thus directly establishing an electrical connection relationship; the control unit 7 establishes a radio connection with the noise detection device 5 (piezoelectric sensor) via a radio receiving module on its circuit board.
The noise detection device 5 (piezoelectric sensor) detects the noise of the water heater 1, converts the noise into a current signal, and transmits the current signal; the control unit 7 receives the current signal and converts it into an audio signal having a frequency opposite to the noise frequency of the water heater 1; then, the noise generator 6 is configured to generate an acoustic wave having a frequency opposite to that of the noise of the water heater 1 based on the audio signal, thereby canceling the noise of the water heater 1 and generating an active noise reduction effect.

In the present embodiment, the noise reduction modes of the gas water heater 1 may be classified into automatic noise reduction and manual noise reduction. In the automatic noise reduction mode, namely after the piezoelectric sensor receives the noise which is more than 40dB and is generated by the gas water heater 1, the electric controller makes a judgment to automatically send out a signal, so that the noise generator 6 starts to work to reduce the noise generated by the water heater 1. In the manual noise reduction mode, namely, the user feels that the noise emitted by the water heater 1 is overlarge, the noise reduction mode on the operator 4 is manually selected, and the electric controller controls the noise generator 6 to start working. In addition, the control unit 7 (electric controller) can adjust the magnitude of the received current signal, so that the user can select different noise reduction intensities.
In this embodiment, the piezoelectric sensor is made of piezoelectric ceramic and PVDF (polyvinylidene fluoride ) film, and when the piezoelectric ceramic is polarized due to the relative displacement of the positive and negative charge centers inside the piezoelectric ceramic affected by noise, the PVDF film transmits an electrical signal to the control unit 7 (electric controller), and the electric controller controls the noise generator 6 to generate opposite frequency noise, so as to reduce the noise generated by the gas water heater 1.
In the present embodiment, the noise detecting device 5 and the noise generator 6 are electrically connected through the control unit 7 (electronic controller), so that the current signal converted by the noise detecting device 5 can be transmitted to the noise generator 6 in a wireless reception form. However, in other embodiments, the control unit 7 may also use other types of control devices, and the noise detection device 5 and the noise generator 6 may also use a wired electrical connection manner; alternatively, the water heater 1 may not have the control unit 7, but the control function thereof is further integrated on the operator 4.
In the present embodiment, the noise generator 6 is integrated on the control unit 7, but in other embodiments, the noise generator 6 may be provided at a noise source of the water heater 1, or part of the noise generator 6 is integrated on the control unit 7, and part of the noise generator 6 is provided at another noise source of the water heater 1 independently.
In the embodiment, the noise generator 6 is integrated on the control unit 7, so that the circuit design of realizing electric connection of the noise generator 6 and the control unit 7 is simplified, the cost is low, the space occupied by parts is saved, and the noise generator 6 is convenient to adjust to generate different noise reduction intensities. In other embodiments, the noise generator 6 is arranged at the noise source of the water heater 1, so that the noise of the water heater 1 is effectively counteracted, and the noise reduction effect is prevented from being influenced due to the fact that the distance is too long.
In this embodiment, the noise detection device 5 (piezoelectric sensor) and the noise generator 6 are respectively integrated on the operator 4 and the control unit 7 (electric controller), and the operator 4 and the electric controller are both disposed in the case 2, so that the noise detection device 5 and the noise generator 6 are both disposed in the case 2, the maximum noise source in the case 2 is ensured to be detected, and the noise generator 6 also counteracts the maximum noise source in the case 2, thereby improving the active noise reduction effect. And the noise generator 6 is arranged at a position close to the noise detection device 5, so that the distance between the noise detection device 5 and the noise generator 6 is shortened, the intensity loss of sound wave propagation is reduced, and the noise reduction effectiveness is improved.
In other embodiments, the setting positions of the noise detecting device 5 (piezoelectric sensor) and the noise generator 6 are adjusted accordingly according to the requirement of the noise reduction effect, and particularly, when there are a plurality of noise detecting devices 5 and a plurality of noise generators 6, a part of the noise detecting device 5 and/or the noise generator 6 can be selected to be arranged on the outer surface of the box 2, so that the noise generated outside the box 2 is counteracted, the noise in the room where the water heater 1 is located is reduced, and a better experience effect is provided for the user.
In this embodiment, the piezoelectric sensor is used as the noise detection device 5, which improves the integration degree on the manipulator 4 and also improves the accuracy of detecting noise. However, in other embodiments, the noise detection device 5 may also employ other devices capable of detecting noise and converting it into an electrical signal. The working principle adopted by the different noise detection devices 5 may be different, and thus, the converted electric signal may be other electric signal forms such as a voltage signal.
