Description

Technical Field

[0001] The present invention relates to the technical field of garbage disposal, and particularly relates to an automatic water supply device and method for a garbage processor. Background Art

[0002] As an emerging kitchen appliance, the food waste processor has been rapidly popularized in the market and is favored by consumers due to its advantages such as quickly crushing kitchen food waste and reducing the amount of garbage transportation.

[0003] Currently, the general kitchen food waste processor is installed under the kitchen sink and connected to the kitchen sink. The cutter head is driven by an AC or DC motor, and the food waste in the crushing cavity is crushed by centrifugal force and then discharged into the sewer. When the garbage processor crushes garbage, by opening the faucet on the sink, water can enter the garbage processor through the sink, thus realizing the water supply of the garbage processor. However, there are also some problems:

[0004] People need to operate the start switch of the garbage processor and manually open the faucet at the same time, and the operation is relatively inconvenient. In addition, after manually opening the faucet, if the water flow is too large, it will cause water to splash out of the sink, which means that after the user finishes using the garbage processor, they still have to clean up the surrounding area of the sink. That is to say, the current garbage processor is relatively inconvenient to use and the user experience is poor.

[0005] In view of this, the inventor of the present invention deeply considered and actively researched and developed in view of the above defects existing in the kitchen food waste processor, and thus this case was generated. Summary of the Invention

[0006] The purpose of the present invention is to provide an automatic water supply device and method for a garbage processor to simplify the user operation and improve the user experience.

[0007] To achieve the above purpose, the technical solution adopted by the present invention is:

[0008] An automatic water supply device for a garbage processor, which includes a water and electricity linkage module connected to the garbage processor. The water and electricity linkage module includes a water inlet pipe, a solenoid valve, a main control circuit board, and a sound collector;

[0009] The water inlet pipe is provided with a water inlet and a water outlet, and the water outlet is connected to the garbage processor; the solenoid valve is arranged on the water inlet pipe to control the on-off of the water inlet pipe;

[0010] The sound collector is used to collect the working noise of the garbage processor; the main control circuit board is connected to the sound collector and the solenoid valve. The main control circuit board reads the noise signal and controls the solenoid valve to open or close according to the noise signal.

[0011] The main control circuit board is provided with an MCU processor and an amplifier module. The sound collector is connected to the amplifier module, the amplifier module is connected to the MCU processor, and the MCU processor is connected to the solenoid valve.

[0012] The main control circuit board is also provided with a power supply circuit module for power supply.

[0013] The water inlet of the water inlet pipe is connected with a three-way valve. The three-way valve includes a water inlet end, a first water outlet end and a second water outlet end. The first water outlet end is connected to the water inlet of the water inlet pipe.

[0014] An automatic water supply method for a garbage processor is realized by using the automatic water supply device as described above, and is specifically as follows:

[0015] Step 1: Collect the working noise signal of the garbage processor.

[0016] Step 2: Continuously read the level of the noise signal within a set time interval, and calculate the frequency and amplitude of the noise signal.

[0017] Step 3: Compare the frequency and amplitude of the noise signal with the reference frequency and reference amplitude. If the frequency of the noise signal is within the threshold range of the reference frequency and the amplitude of the noise signal is not less than the reference amplitude, it indicates that the garbage processor is in a working state, then open the solenoid valve to supply water to the garbage processor; otherwise, it indicates that the garbage processor is in a stopped state and the solenoid valve is closed.

[0018] In the step 1, a directional microphone is used to collect the noise signal of the garbage processor.

[0019] Among the continuously read noise signal levels in the step 2, obtain the maximum level and the minimum level. The frequency of the noise signal can be calculated through two adjacent maximum values and two adjacent minimum values. Subtracting the minimum value from the maximum value of the continuously read noise signal can obtain the amplitude.

[0020] After adopting the above solution, the present invention re - sets a water inlet pipeline under the sink to supply water to the garbage processor, without the need to supply water through the faucet of the sink. This means that the water supply of the garbage processor does not bring unnecessary cleaning work to the user, thus improving the user experience. In addition, for the on - off control of the water inlet pipe, the present invention utilizes the specific frequency noise with a certain amplitude generated by the rotation of the motor and the crushing of garbage when the garbage processor is working. Therefore, a reference frequency and a reference amplitude are preset. Then, a sound collector is used to detect the noise generated by the garbage processor and send it into the main control circuit board. The main control circuit board calculates the corresponding frequency and amplitude according to the collected sound, and then compares it with the set reference frequency and reference amplitude to determine whether the noise signal is generated when the garbage processor is working, and thus knows the working state of the garbage processor, and controls whether the solenoid valve needs to be opened based on this. That is to say, when the user uses the garbage processor, as long as the switch of the garbage processor is turned on, the water supply of the garbage processor will be automatic. The user can achieve one - key garbage cleaning, and the operation is convenient and simple, further improving the user experience. Description of the Drawings

[0030] As Figure 1 and Figure 2 shown, the present invention discloses an automatic water supply device for a garbage processor, which includes a garbage processor 10 and a hydro - electric linkage module 20 connected to the garbage processor 10.

[0031] In this embodiment, the garbage processor 10 is also located under the sink and is connected to the sink. However, a new water circuit (i.e., the water and electricity linkage module 20) is provided under the sink of the garbage processor 10 for water supply.

[0032] In this embodiment, the water and electricity linkage module 20 includes a water inlet pipe 21, a solenoid valve 22, a main control circuit board 23, and a sound collector 24. The water inlet pipe 21 is provided with a water inlet 211 and a water outlet 212. The water inlet 211 is connected to other water supply pipes or water tanks in the kitchen, and the water outlet 212 is connected to the garbage processor 10. The present invention supplies water to the garbage processor 10 through the water inlet pipe 21. The solenoid valve 22 is arranged on the water inlet pipe 21 to control whether the water inlet pipe 21 supplies water to the garbage processor 10.

[0033] The sound collector 24 is used to collect noise and is implemented by a microphone. In this embodiment, the sound collector 24 mainly collects the sound information generated by the rotation of the motor of the garbage processor 10 during its operation. In order to better collect these sounds, the sound collector 24 is implemented by a directional microphone, which is arranged facing the garbage processor 10. The arrangement of the directional microphone can avoid the interference of external noise and ensure the voltage stability of the product operation.

[0034] The main control circuit board 23 is connected to the sound collector 24 and the solenoid valve 22. The main control circuit board 23 reads the noise signal and controls the opening or closing of the solenoid valve 22 according to the noise signal. Specifically, as Figure 3 and 4 shown, an MCU processor 231 and an amplifier module 232 are provided on the main control circuit board 23. The amplifier module 232 is used to connect the microphone to amplify the noise signal collected by the microphone. The MCU processor 231 is connected to the amplifier module 232. The MCU processor 231 reads the noise signal amplified by the amplifier module 232, determines the sound frequency and amplitude according to the noise signal, then compares the determined sound frequency and amplitude with the set reference frequency and reference amplitude, and finally controls the opening or closing of the solenoid valve 22 according to the comparison result.

[0035] A power supply circuit module 233 is also provided on the main control circuit board 23. The power supply circuit module supplies power to the water and electricity linkage module to ensure the normal operation of the water and electricity linkage module.

[0036] In the actual application process, the water inlet pipe 21 in the water-electricity linkage module 20 shares the same water inlet path with the faucet of the sink. Therefore, in this embodiment, a three-way valve 30 is used to connect the water inlet pipe 21, the faucet of the sink, and the water inlet path of the kitchen. The three-way valve 30 includes a water inlet end, a first water outlet end, and a second water outlet end. The first water outlet end is connected to the water inlet 211 of the water inlet pipe 21, and the second water outlet end is connected to the faucet of the sink.

[0037] In summary, the present invention newly sets up a water inlet pipeline under the sink to supply water to the garbage processor 10, without the need to supply water through the faucet of the sink. This means that the water supply of the garbage processor 10 does not bring unnecessary cleaning work to the user, thereby improving the user experience. In addition, for the on-off control of the water inlet pipe 21, the present invention is realized by the solenoid valve 22 in cooperation with the main control circuit board 23 and the sound collector 24. The sound generated when the garbage processor 10 works is collected by the sound, and the main control circuit board 23 determines whether the garbage processor 10 is working according to the collected sound. When the garbage processor 10 is working, the solenoid valve 22 is opened to supply water to the garbage processor 10. When the garbage processor 10 is not working, the solenoid valve 22 is controlled to be in the closed state. That is to say, when the user uses the garbage processor 10, as long as the switch of the garbage processor 10 is turned on, the water supply of the garbage processor 10 will be automatically carried out, and the user can realize one-key garbage cleaning, and the operation is convenient and simple. Generally speaking, the switch of the garbage processor 10 is set on the wall. Of course, it can also be set in other positions or realized by other means such as remote control. The present invention does not limit this.

[0038] As Figure 5 shown, based on the same inventive concept, the present invention also discloses a method for automatically supplying water to the garbage processor 10, and this method is realized based on the above automatic water supply device. Specifically as follows:

[0039] Step 1, collect noise signals; in this embodiment, a directional microphone is used to collect the noise of the garbage processor 10.

[0040] Step 2, continuously read the level of the noise signal within a set time interval, and calculate the frequency and amplitude of the noise signal;

[0041] Step 3, compare the frequency and amplitude of the noise signal with the reference frequency and reference amplitude. If the frequency of the noise signal is within the threshold range of the reference frequency and the amplitude of the noise signal is not less than the reference amplitude, it indicates that the garbage processor 10 is in the working state, and then the solenoid valve 22 is opened to supply water to the garbage processor 10; otherwise, it indicates that the garbage processor 10 is in the rest state, and the solenoid valve 22 is closed.

[0042] The present invention utilizes the specific frequency noise with a certain amplitude generated by the rotation of the motor and the crushing of garbage when the garbage processor 10 is working. Therefore, a reference frequency and a reference amplitude are preset in advance. Then, a directional microphone is used to detect the noise generated by the garbage processor 10 and send it to the main control circuit board 23. The main control circuit board 23 calculates the corresponding frequency and amplitude based on the collected sound, and then compares it with the set reference frequency and reference amplitude to determine whether the noise signal belongs to the noise generated when the garbage processor 10 is working, thereby knowing the working state of the garbage processor 10 and controlling whether the solenoid valve 22 needs to be opened. To determine whether the garbage processor 10 is working, when the garbage processor 10 is working, the solenoid valve 22 is opened to supply water to the garbage processor 10. If the garbage processor 10 is not working, the solenoid valve 22 is controlled to be in a closed state.

[0043] When the user turns on the switch of the garbage processor 10, the garbage processor 10 will start working. At this time, even if there is external interference, the frequency of the noise signal collected by the directional microphone will have a certain similarity to the reference frequency. Then, by combining the judgment of the amplitude, it can be accurately determined that the garbage processor 10 is in a working state. At this time, controlling the solenoid valve 22 to open can realize the water supply to the garbage processor 10.

[0044] In this embodiment, in step 2, among the continuously read noise signal levels, the maximum level and the minimum level are obtained. The frequency of the noise signal can be calculated through two adjacent maximum values and two adjacent minimum values. The amplitude can be obtained by subtracting the minimum value from the maximum value of the continuously read noise signal.

[0045] As mentioned above, it is only an embodiment of the present invention, and it does not impose any limitation on the technical scope of the present invention. Therefore, any minor modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
