Background

Food waste disposers are rapidly gaining popularity in the market as an emerging kitchen appliance, and are enjoyed by consumers due to their advantages of rapidly crushing kitchen food waste, reducing the volume of waste transportation, and the like.

Current kitchen food waste disposers are typically mounted below and connected to a kitchen sink. The cutter disc is driven by an alternating current or direct current motor, and the food waste in the crushing cavity is crushed by centrifugal force and then discharged into a sewer. When the garbage disposer crushes garbage, a water tap on the water tank is opened, water flow can enter the garbage disposer through the water tank, and therefore water supply of the garbage disposer is achieved. However, there are problems with this:

people need to operate the starting switch of the garbage disposer and also need to manually open the water faucet, so that the operation is inconvenient. In addition, if the water flow is too high after the faucet is manually opened, water may splash out of the sink, which means that the user has to clean the periphery of the sink after using the garbage disposer. That is, the current garbage disposer is inconvenient to use and has poor user experience.

In view of the above, the present invention has been made in an effort to overcome the above-mentioned shortcomings of the kitchen food waste disposer and has been made.

The garbage disposer 10 is disposed under the water tank 80, and has a water inlet and a water outlet, the water inlet is connected to the water inlet pipe 20, and the water outlet is connected to the water tank drain pipe 30. When the garbage disposer 10 is in operation, water in the water inlet pipe 20 is supplied to the disposer through the water inlet, and garbage crushed by the garbage disposer 10 flows out of the water outlet along with water flow and is discharged from the water discharge pipe 30 of the water sink. Whether the garbage disposer 10 works or not can be directly controlled by a control switch, and the control switch can be arranged on a wall body for convenience in operation. Alternatively, the operation state of the garbage disposer 10 can be controlled by a remote controller or the like.

A water path control mechanism 50 is provided on the water inlet pipe 20, and the water path control mechanism 50 is used to open or close the water inlet pipe 20 to determine whether to supply water to the garbage disposer 10. In this embodiment, the waterway control mechanism 50 is implemented by an electromagnetic valve. Of course, the waterway control mechanism 50 may be implemented by other structures as long as the on/off of the water inlet pipe 20 can be controlled.

The microphone 60 is disposed on the sink drain pipe 30 and communicates with the sink drain pipe 30 to collect sound information generated by airflow disturbance generated in the sink drain pipe 30 when the garbage disposer 10 is in operation. In order to ensure that the sound information generated by the airflow disturbance can be accurately collected, in this embodiment, the microphone 60 is connected to the water tank drain pipe 30 through a capillary tube 70, one end of the capillary tube 70 is communicated with the inner cavity of the water tank drain pipe 30, and the other end is connected to the collection end of the microphone 60.

The main control circuit board 40 is connected to the microphone 60 and the waterway control mechanism 50, and the main control circuit board 40 obtains the sound information generated by the air flow disturbance in the drain pipe 30 of the sink through the microphone 60, and controls the waterway control mechanism 50 to open or close the water inlet pipe 20 according to the air flow disturbance information. Specifically, the main control circuit board 40 is provided with an MCU processor 41 and an amplifier module 42, and the amplifier module 42 is used for connecting the microphone 60 so as to amplify the sound signal collected by the microphone 60. The MCU processor 41 is connected to the amplifier module 42, and the MCU processor 41 reads the sound signal amplified by the amplifier module 42 and determines whether the intensity of the sound signal is within a threshold range, and controls the water path control mechanism 50 to open the water inlet pipe 20 if the intensity of the sound signal is within the threshold range, or controls the water path control mechanism 50 to close the water inlet pipe 20 if the intensity of the sound signal is not within the threshold range.

The main control circuit board 40 is further provided with a power circuit module 43, and the power circuit module 43 provides power to ensure that the automatic water supply device can work normally.

In summary, the present invention provides a water inlet pipe 20 below the water tank 80 for supplying water to the garbage disposer 10 without supplying water through the faucet of the water tank, which means that the water supply of the garbage disposer 10 does not bring unnecessary cleaning work to the user, thereby improving the user experience. In addition, for on-off control of the water inlet pipe 20, the water path control mechanism 50 is matched with the main control circuit board 40 and the microphone 60, and the microphone 60 is arranged on the water tank drain pipe 30, so that the water tank drain pipe 30 can generate airflow disturbance when the garbage disposer 10 works, and the microphone 60 can detect sound generated by the airflow disturbance. The main control circuit board 40 judges whether the garbage disposer 10 is working according to the collected sound, and when the garbage disposer 10 is working, the waterway control mechanism 50 opens the water inlet pipe 20 to supply water to the garbage disposer 10; when the garbage disposer 10 is not in operation, the waterway control mechanism 50 closes the inlet pipe 20. That is, when the user uses the garbage disposer 10, the user only needs to turn on the switch of the garbage disposer 10, the water supply of the garbage disposer 10 can be automatically performed, the user can clean the garbage by one key, and the operation is convenient and simple.

According to the method, when the garbage disposer 10 works, negative pressure is formed in the garbage disposer 10, so that airflow disturbance occurs in a water tank drain pipe 30 connected with the garbage disposer 10, and the airflow disturbance inevitably causes air vibration, so that sound is generated. Therefore, the present invention determines whether the garbage disposer 10 is in operation by collecting the sound generated by the airflow disturbance and then determining whether the intensity of the sound is within a threshold range. When the garbage disposer 10 is in the working state, the water inlet pipe 20 is further opened, and automatic water supply to the garbage disposer 10 is realized. According to the invention, a user only needs to control the working state of the garbage disposer 10, and automatic water supply can be realized without additional manual water supply operation, so that the use operation of the garbage disposer 10 is simplified. And, whether water supply is controlled through collecting the air current disturbance condition in the water tank drain pipe 30, can effectively reduce external factor interference, improve the accuracy of water supply control.

The above description is only exemplary of the present invention and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above exemplary embodiments according to the technical spirit of the present invention are within the technical scope of the present invention.
