Embodiment 1

[0037] Such as figure 1 As shown, this embodiment provides an active noise reduction gas water heating device, which includes a water heating device body 1 and a solenoid valve 2, wherein the solenoid valve 2 is arranged on the water inlet end of the water heating device body 1, and also includes a pressure detection device 4, noise reduction assembly 5 and controller, wherein the pressure detector 4 and noise reduction assembly 5 are electrically connected to the controller respectively, and the pressure detector 4 is arranged on the solenoid valve for detecting the solenoid valve 2 The pressure difference and the detection result are fed back to the controller, and the controller controls the noise reduction component 5 to emit noise reduction according to the feedback signal so that the noise reduction component 5 and the noise generated by the gas water heating device cancel each other .

[0038] In this embodiment, the gas water heater may be a gas water heater or a wall...

Embodiment 2

[0046] Such as figure 2 As shown, this embodiment provides an active noise reduction method for a gas water heater, which is applied to the gas water heater described in Embodiment 1. The noise generated by the gas water heater mainly includes fan noise, combustion noise and Water flow noise, the frequency spectrum of the above-mentioned noise is relatively fixed, and the above-mentioned noise is mainly changed by the influence of the combustion heat load. Therefore, the noise spectrum can be obtained by determining the combustion heat load. On the contrary, the principle that the amplitudes of the noise cancel each other out, the gas water heating device of this embodiment applies the gas water heating device as described in Embodiment 1, and calculates the current gas water heating device by detecting the pressure difference at both ends of the solenoid valve. The size of the noise, so that the controller controls the noise reduction device to emit noise reduction according...

Abstract

The invention discloses a gas water heating device and method with an active noise canceling function. The gas water heating device comprises a water heating device body, an electromagnetic valve, a pressure detector, a noise canceling assembly and a controller, wherein the electromagnetic valve is arranged at the water inlet end of the gas water heating device body, the pressure detector and thenoise canceling assembly are electrically connected with the controller, the pressure detector is arranged on the electromagnetic valve and is sued for detecting a pressure difference of the electromagnetic valve and feeding a detection result back to the controller, and the controller controls the noise canceling assembly to make noise canceling sounds according to a fed-back signal, so that thenoise canceling sounds made by the noise canceling assembly and noise generated by the gas water heating device in work are mutually counteracted. The gas water heating device is simple in structure;and the noise canceling sounds made by the noise canceling assembly counteract the working noise of the gas water heating device, so that the noise canceling effect of the gas water heating device isfurther improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an active noise reduction gas water heating device and method. Background technique [0002] During the working process of the gas water heating device, noise will be generated due to gas combustion, water flow or fan operation, etc., and the generated sound will be transmitted directly to the outside to cause noise pollution. In related technologies, most of the noise reduction technologies for gas water heaters are mainly measures such as adjusting the air-fuel ratio and changing the fan speed, but the noise reduction effect is not obvious; in addition, there are active noise reduction technologies, but the cost is relatively high. high. Contents of the invention [0003] The purpose of the present invention is to solve one of the problems existing in the related art at least to a certain extent. Therefore, the present invention proposes an active noise-reducing...
