Description

[Technical Field]

[0001] This invention relates to a power noise reduction adapter, a power noise reduction method, and a food processing apparatus, and particularly to a power noise reduction adapter, a power noise reduction method, and a food processing apparatus for improving the flavor of food processed by the food processing apparatus. [Previous Technology]

[0002] Food processing equipment often requires the use of AC power signals as signals when processing food. For example, espresso machines or steam tea makers need to use high-pressure, high-heat steam to extract components from coffee beans or tea leaves to obtain coffee or tea. If the AC power signal contains a lot of noise, it will affect the stability of the pressure and / or temperature of the steam generated, resulting in the taste and quality of the extracted coffee or tea being less than expected.

[0003] For example, coffee grinders and spice grinders use AC power signals to drive the grinding blades. If the AC power signal contains a lot of noise, the particle size and taste of the ground coffee or spices will not be as expected. As another example, bread makers, brewing machines, or dairy fermentation machines mainly use AC power signals to control the fermentation temperature. If the fermentation temperature is unstable due to noise in the AC power signal, the taste of the produced food may be unpleasant.

[0004] However, food processing equipment is generally considered to be electronic and electrical products that do not require high signal accuracy, and therefore does not process noise in the AC power signal. In other words, noise in the AC power signal may affect the taste of the food processed by the food processing equipment, and in order to improve the taste of the food processed by the food processing equipment, it is necessary to provide a solution that can process noise in the AC power signal. [Summary of the Invention]

[0016] Based on one objective of the present invention, an embodiment of the present invention provides a power supply noise reduction method for improving the flavor of food in a food processing device, which is executed in a power supply noise reduction adapter and includes the following steps: splitting an input power signal into a first shunt power signal, a second shunt power signal, and a third shunt power signal in parallel; performing voltage reduction and current limiting on the first shunt power signal; performing frequency division on the first shunt power signal after voltage reduction and current limiting at least once, and using it to output at least one frequency division signal; capturing and accumulating a plurality of noise signals from the second shunt power signal to generate a noise accumulation signal, and outputting a trigger signal when the noise accumulation signal accumulates to a threshold value; using the third shunt power signal as the output power signal of the power supply noise reduction adapter; and presenting the trigger signal and the frequency division signal in a light-emitting manner.

Implementation Method

[0018] The power noise reduction adapter, power noise reduction method, and food processing apparatus of the present invention mainly use a parallel connection to split the input power signal into three shunt power signals. One of the three shunt power signals is stepped down, current-limited, and frequency-divided; another of the three shunt power signals is used for noise extraction and accumulation; and yet another of the three shunt power signals is used as the output power signal. Through the above processing of the two shunt power signals, a specific grounding method is generated, deriving noise from the input power signal, thereby suppressing and reducing noise in the output power signal, resulting in a clean AC power signal. The following will describe in detail the possible embodiments of the present invention with reference to the drawings. However, it should be noted that the following implementation details are not intended to limit the scope of the claims made by the present invention, but are merely for the convenience of those skilled in the art to understand.

[0019] First, please refer to Figure 1, which is a block diagram of a food processing apparatus for enhancing the flavor of food according to an embodiment of the present invention. The food processing apparatus 2 includes a power module 21, which is mainly used to receive the power output signal AC_OUT output by the power noise reduction adapter 1. The power output signal AC_OUT is an AC power signal, and after the power input signal AC_IN is processed by the power noise reduction adapter 1, the power output signal AC_OUT is a power signal with little or no noise. In this embodiment, the power noise reduction adapter 1 is independently configured outside the food processing apparatus 2 and electrically connected to the power module 21 of the food processing apparatus 2, and the power module 21 receives the output power signal AC_OUT so that the food processing apparatus 2 can use the output power signal AC_OUT to process the food.

[0020] Next, please refer to Figure 2, which is a block diagram of a food processing apparatus for enhancing the flavor of food according to another embodiment of the present invention. Unlike the embodiment of Figure 1, in this embodiment, a power noise reduction adapter 1 is provided in the food processing apparatus 2. In addition, regardless of whether it is the embodiment of Figure 1 or Figure 2, the food processing apparatus 2 can be an espresso machine, a coffee grinder, a spice grinder, a bread maker, a brewing machine, a dairy fermentation machine, or a steam tea maker, and the present invention is not limited thereto.

[0021] Taking an espresso machine as an example, an espresso machine is used to make espresso. The crema on top of the espresso must be consumed before it dissipates, otherwise it will lose its smooth texture. The golden crema is a key element for making the espresso layered and delicious, and the steam must be stably maintained at 9 bar and a specific temperature to extract the golden crema from the coffee beans. The power noise reduction adapter 1 of the present invention can provide a power output signal AC_OUT with little or no noise. Therefore, an espresso machine using the power noise reduction adapter 1 of the present invention can provide steam that is stably maintained at 9 bar and a specific temperature, so that every cup of espresso made has golden crema, thereby enhancing the taste of the food.

[0022] Next, please refer to Figure 3, which is a block diagram of a power noise reduction adapter for improving the taste of food in a food processing device according to an embodiment of the present invention. The power noise reduction adapter 1 includes an input line W0, a first shunt line W1, a second shunt line W2, a third shunt line W3, a step-down current limiting device 11, a frequency reduction noise reduction device 12, a noise acquisition and accumulation triggering device 13, and an output line W4.

[0023] The input line W0 is used to receive the AC input power signal AC_IN. The input power signal is AC mains AC_IN. The frequency of the AC mains is 50 or 60 Hz, and the voltage of the AC mains is 100 volts, 110 volts, or 200 to 240 volts (but not limited to these, the voltage can be between 100 and 240 volts). For example, the frequency and voltage of the AC mains in Taiwan are 60 Hz and 110 volts.

[0024] The first shunt line W1, the second shunt line W2 and the third shunt line W3 are electrically connected to the input line W0, wherein the input power signal AC_IN generates a first shunt power signal, a second shunt power signal and a third shunt power signal on the first shunt line W1, the second shunt line W2 and the third shunt line W3.

[0025] The step-down current limiting device 11 is electrically connected to the first shunt line W1 and is used to step down and limit the current of the first shunt power signal. The step-down current limiting device 11 includes a high-voltage capacitor and a current limiting device electrically connected to each other to perform step-down and current limiting. The frequency division and noise reduction device 12 is electrically connected to the step-down current limiting device 11 and is used to perform at least one frequency division on the first shunt power signal after step-down and current limiting, and is used to output at least one frequency division signal. The frequency division and noise reduction device 12 may include a plurality of frequency division units connected in series. The plurality of frequency division units are used to perform one to a plurality of frequency divisions on the first shunt power signal, and are used to output a plurality of frequency division signals corresponding to the plurality of frequency divisions generated by one to a plurality of frequency divisions, wherein the divisor of each of the plurality of frequency division units can be an even number, such as 2, but the present invention is not limited thereto, and the divisor may also be an odd number. In addition, the above-described implementation of the frequency division and noise reduction device 12 is not intended to limit the present invention, and the frequency division and noise reduction device 12 may also include a plurality of frequency division units connected in parallel.

[0026] The noise acquisition and accumulation triggering device 13 is electrically connected to the second shunt line W2, and is used to acquire and accumulate a plurality of noise signals from the second shunt power signal to generate a noise accumulation signal, and output a trigger signal when the noise accumulation signal accumulates to a threshold value. In one embodiment, the noise acquisition and accumulation triggering device 13 includes a pulse transformer (in one implementation, the pulse transformer has a high-voltage capacitor, i.e., the pulse transformer is a high-voltage capacitor pulse transformer) and a control chip electrically connected to each other, so as to acquire and accumulate a plurality of noise signals. The pulse transformer can acquire and accumulate a plurality of noise signals, and the control chip outputs the noise accumulation signal as a trigger signal when the noise accumulation signal accumulates to a threshold value. However, the present invention is not limited to the implementation of the noise acquisition and accumulation triggering device. The output line W4 is electrically connected to the third shunt line W3, and is used to use the third shunt power signal as the output power signal AC_OUT of the power noise reduction adapter 1.

[0027] The frequency reduction signal and the trigger signal are released to ground in a specific manner. The frequency reduction signal and the trigger signal are related to noise. Therefore, after being released to ground, the noise of the third shunt power signal after the input power signal AC_IN is reduced, so that the output power signal AC_OUT has low noise or even no noise. In this embodiment of the invention, the power noise reduction adapter further includes a light-emitting device 14, which is electrically connected to the frequency reduction noise reduction device 12 and the noise acquisition and accumulation trigger device 13. The light-emitting device 14 includes a plurality of light-emitting units and is used to receive the trigger signal and the frequency reduction signal, wherein the plurality of light-emitting units emit light according to the trigger signal and the frequency reduction signal. Furthermore, in other embodiments, the light-emitting device 14 can be replaced by, for example, a buzzer or other electroacoustic or electro-optical element. Simply put, the light-emitting device 14 is used as a noise release device, the purpose of which is to release the noise signal. Since the trigger signal and the frequency reduction signal are essentially composed of noise, the noise release device is mainly used to receive and release the trigger signal and the frequency reduction signal.

[0028] When the power noise reduction adapter 1 is independently configured outside the food processing device 2, the power noise reduction adapter 1 further includes a housing C, wherein the input line W0, the first shunt line W1, the second shunt line W2, the third shunt line W3, the step-down current limiting device 11, the frequency reduction noise reduction device 12, the noise acquisition and accumulation triggering device 13, and the light-emitting device 14 are disposed within the housing C. The housing C is provided with at least one opening, an input power slot IP, and an output power slot OP. The opening is used to expose the light-emitting part of the light-emitting device 14. The input power slot IP and the output power slot OP are respectively used to connect the input line W0 and the output line W4, and the input power slot IP and the output power slot OP are respectively used to connect the input wire and the output wire.

[0029] Furthermore, please refer to Figure 4, which is a flowchart of a power supply noise reduction method for improving the flavor of food in a food processing apparatus according to an embodiment of the present invention. The power supply noise reduction method for improving the flavor of food in a food processing apparatus is executed in a power supply noise reduction adapter and includes the following steps. First, in step S41, the input power signal is split into a first split power signal, a second split power signal, and a third split power signal through parallel connection. The first split power signal, the second split power signal, and the third split power signal are processed in parallel in steps S42-S44, steps S45 and S46, and step S47.

[0030] In step S42, the first shunt power signal is stepped down and current-limited. In step S43, the stepped-down and current-limited first shunt power signal is frequency-divided at least once and used to output at least one frequency-divided signal. In step S44, at least one frequency-divided signal is presented in an illuminated manner to release the frequency-divided signal to ground. In step S45, a plurality of noise signals are captured and accumulated from the second shunt power signal to generate a noise accumulation signal, and a trigger signal is output when the noise accumulation signal accumulates to a threshold value. In step S46, the trigger signal is presented in an illuminated manner to release the trigger signal to ground. In step S47, the third shunt power signal is used as the output power signal of the power noise reduction adapter.

[0031] In summary, the power noise reduction adapter, power noise reduction method and food processing device for improving the taste of food provided by the present invention have at least the following characteristics: (1) The input power signal is split into three split power signals, two of which are processed to release noise, thereby reducing the noise of the other split power signal and providing it as a pure output power signal to the food processing device; (2) Since the food processing device uses a pure output power signal, the food processed by the food processing device is made more delicious; and (3) Since the taste of the food processed by the food processing device is not affected by the noise of the power signal, restaurants can provide customers with stable quality food without hiring professional catering staff.
