[0027] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] The noise reduction method for a food processing device, the noise reduction device for a food processing device, a computer-readable storage medium, and a food processing device proposed in embodiments of the present invention will be described below with reference to the accompanying drawings.

[0029] Figure 1 It is a flowchart of a noise reduction method for a food processing device according to some embodiments of the present invention.

[0030] In some embodiments of the present invention, the food processing device may be a household electrical appliance device including a heating plate and a blower, such as a pressure cooker, a rice cooker, an electric rice cooker, an air fryer, a microwave oven, an oven, a soybean milk machine, or a juice machine.

[0031] As Figure 1 shown, the noise reduction method for the food processing device according to the embodiments of the present invention may include the following steps:

[0032] S1. During the operation of the food processing device, obtain the temperature inside the cavity of the food processing device.

[0033] S2. When the temperature inside the cavity exceeds the upper temperature threshold, control the heater and the blower speed of the food processing device.

[0034] Specifically, taking a food processing device, an air fryer for example, when a user uses the air fryer, the working mode is selected through the display panel (or mechanical buttons) of the air fryer. Among them, when the air fryer is equipped with a mute button, it is also necessary to determine whether the user presses the mute button before executing the noise reduction strategy of this application; when the air fryer is not equipped with a mute button, the noise reduction strategy is executed by default. When the user presses the start working button, the main control board of the air fryer controls the relay of the heating plate to conduct (that is, the heater starts to work), and at the same time drives the fan to start, and blows the heat of the heating plate to the food in the pot through the fan. The temperature inside the food processing device is collected in real time by a temperature sensor arranged inside the food processing device. The temperature inside the cavity refers to the temperature of the cavity in the food processing device, and then how to control the heater and the fan is determined according to the size of the temperature inside the cavity. For example, when the temperature inside the cavity exceeds the upper temperature threshold and lasts for a certain period of time (such as 10 s), it is considered that the current temperature inside the cavity is too high, and the corresponding fan speed is also relatively high. At this time, the operating power of the heating plate can be controlled to decrease, or the heating plate can be directly turned off, and at the same time the fan speed is decreased to achieve the purpose of reducing noise. Another example is that when the temperature inside the cavity is lower than the lower temperature threshold and lasts for a certain period of time (such as 10 s), it is considered that the current temperature inside the cavity is too low, which will affect the cooking effect. The heating plate can be controlled to start working, or the operating power of the heating plate can be increased, and at the same time the fan speed is controlled to gradually increase, so that the temperature inside the cavity rises more evenly and the cooking effect is guaranteed. Therefore, by dynamically adjusting the heater and the fan speed according to the temperature inside the cavity obtained in real time, compared with the method of the fan working at a constant speed throughout the working process, the overall low-noise performance of the product can be achieved, and the effect of noise reduction and energy saving can be achieved.

[0035] The noise reduction method of the food processing device according to the embodiment of the present invention will be described in detail below.

[0036] According to some embodiments of the present invention, when the temperature inside the cavity exceeds the upper temperature threshold, controlling the heater and the fan speed of the food processing device includes: controlling the heater to stop working, and controlling the fan speed to decrease at a first preset rate. The first preset rate can be calibrated according to the actual situation.

[0037] Further, in some embodiments of the present invention, during the process of controlling the speeds of the heater and the fan, the method further includes: if the temperature inside the cavity is lower than the preset lower temperature threshold, controlling the heater to start working, and controlling the fan speed to increase at a second preset rate. The preset lower temperature threshold and the second preset rate can be calibrated according to the actual situation.

[0038] Specifically, two limit values, namely the upper temperature limit threshold and the lower temperature limit threshold, are set. When the temperature inside the cavity collected by the temperature sensor is greater than the upper temperature limit threshold, the heater is controlled to be in the off state. In this way, the rising speed of the temperature inside the cavity will be greatly reduced. At this time, the blower does not need to operate at a constant maximum speed, and a certain reduction rate (the first preset rate) can be used to control the blower. On the one hand, it can avoid the temperature inside the pot from decreasing too fast, and on the other hand, it can achieve the purpose of reducing noise. After the heater stops working for a period of time, the temperature inside the cavity will drop. When the temperature inside the cavity is less than the lower temperature limit threshold, the heater is controlled to turn on for heating, and at the same time, the speed of the blower is controlled to increase according to the second preset rate. The speed of the blower gradually increases, thereby accelerating the heat transfer and making the temperature of the space inside the cavity rise more evenly to ensure the cooking effect.

[0039] It should be noted that the speed of the blower can be controlled to decrease according to the first preset rate by reducing the duty cycle of the main control board driving the blower. Similarly, the speed of the blower can be controlled to increase according to the second preset rate by increasing the duty cycle of the main control board driving the blower.

[0040] In some other embodiments of the present invention, when the temperature inside the cavity exceeds the upper temperature limit threshold, the heater and the blower speed of the food processing device are controlled, including: controlling the operating power of the heater to decrease at the first rate and controlling the speed of the blower to decrease at the third preset rate. Among them, the first rate and the third preset rate can be calibrated according to the actual situation.

[0041] Furthermore, in some embodiments of the present invention, during the process of controlling the speeds of the heater and the blower, the method further includes: if the temperature inside the cavity is lower than the preset lower temperature limit threshold, controlling the operating power of the heater to increase at the second rate and controlling the speed of the blower to increase at the fourth preset rate. Among them, the second rate and the fourth preset rate can be calibrated according to the actual situation.

[0042] Specifically, when the temperature inside the cavity collected by the temperature sensor is greater than the upper temperature limit threshold, the heating power of the heater is controlled to decrease at the first rate. In this way, the rising speed of the temperature inside the cavity will gradually decrease. At this time, the blower does not need to operate at a constant maximum speed, and a certain reduction rate (the third preset rate) can be used to control the blower. On the one hand, it can avoid the temperature inside the pot from decreasing too fast, and on the other hand, it can achieve the purpose of reducing noise. When the operating power of the heater gradually decreases and drops to a certain value, the temperature inside the cavity will gradually drop. When the temperature inside the cavity is less than the lower temperature limit threshold, the operating power of the heater is controlled to gradually increase at the second rate, and at the same time, the speed of the blower is controlled to increase at the fourth preset rate. The speed of the blower gradually increases, thereby accelerating the heat transfer and making the temperature of the space inside the cavity rise more evenly to ensure the cooking effect.

[0043] In some embodiments of the present invention, the noise reduction method of the above food processing device further includes: responding to a control instruction and determining a target working time of the food processing device according to the control instruction; when the working time of the food processing device reaches the target working time, controlling the heater to stop working and controlling the blower to operate at a preset speed.

[0044] In some embodiments of the present invention, when controlling the blower to operate at a preset speed, the method further includes: when the temperature in the cavity is less than or equal to a first preset temperature and lasts for a first preset time, controlling the blower to stop working. Wherein, the first preset temperature and the first preset time can be calibrated according to actual situations. For example, the first preset time can be 2s.

[0045] That is to say, the control instruction includes a function selection instruction and a start working instruction. When receiving the function selection instruction, the target working time is determined according to the function selection instruction. When receiving the start working instruction, controlling the food processing device to start working. During the working process of the food processing device, the heater and the blower speed are controlled according to the control logic of the above embodiments. When the working time reaches the target working time, first control the heater to stop working, and then control the blower to operate at a preset speed (low speed) to prevent the temperature in the cavity from dropping too fast and affecting the cooking effect, and obtain the temperature in the cavity in real time. When the temperature in the cavity is less than or equal to the first preset temperature and lasts for the first preset time, control the blower to be in a stopped working state and enter the standby state.

[0046] Thus, in the working operation state of the food processing device, the noise reduction method of the present invention adjusts the speed of the blower in real time according to the temperature in the cavity, and the speed of the blower slowly switches between low speed and high speed, so that the noise generated by the blower is smaller than that of ordinary food processing devices.

[0047] As a specific example, as Figure 2 shown, the noise reduction method of the food processing device of the present invention may include the following steps:

[0048] S101, the user uses the selection function button.

[0049] S102, whether the mute mode button is pressed. If yes, execute step S103; if no, execute step S103.

[0058] S111, Control the relay of the heater to disconnect and control the blower speed to gradually decrease.

[0059] S112, Determine whether the working time of the function has ended. If yes, execute step S119; if no, execute step S113.

[0060] S113, Determine whether the temperature t inside the cavity of the food processing device satisfies t ≤ t1 and lasts for more than 10 s. If yes, execute step S114; if no, return to step S111.

[0061] S114, Control the heater relay to close and control the blower speed to gradually increase.

[0062] S115, Determine whether the working time of the function has ended. If yes, execute step S116; if no, execute step S109.

[0063] S116, Control the heater to stop heating and control the blower to operate at a low speed.

[0067] S120, determine whether it holds that the temperature t in the cavity of the food processing device is ≤ t3 and lasts for more than 2 s. If so, execute step S121; if not, execute step S119.

[0068] S121, control the blower to stop and enter the standby state.

[0069] It should be noted that the specific values mentioned above are only for detailed illustration of the implementation of the present invention by way of example, and should not be construed as a limitation of the present invention. In other examples or embodiments or implementations, other values can be selected according to the present invention, and no specific limitation is made here.

[0070] In summary, according to the noise reduction method of the food processing device in the embodiments of the present invention, during the operation of the food processing device, the temperature in the cavity of the food processing device is acquired, and when the temperature in the cavity exceeds the upper temperature limit threshold, the heater and the blower speed of the food processing device are controlled. Thus, this method can, during the operation of the food processing device, acquire the temperature in the cavity in real time, and when the temperature in the cavity exceeds a certain value, control the heater and the blower speed, reduce the operation noise of the device, and improve the user experience.

[0071] Corresponding to the above embodiments, the present invention also proposes a noise reduction device for a food processing device.

[0072] As Figure 3 shown, the noise reduction device 100 of the food processing device in the embodiments of the present invention may include: a temperature acquisition module 110 and a control module 120.

[0073] Among them, the temperature acquisition module 110 is used to acquire the temperature in the cavity of the food processing device during the operation of the food processing device. The control module 120 is used to control the heater and the blower speed of the food processing device when the temperature in the cavity exceeds the upper temperature limit threshold.

[0074] According to some embodiments of the present invention, when the temperature in the cavity exceeds the upper temperature limit threshold, the control module 120 controls the heater and the blower speed of the food processing device, and specifically is used to: control the heater to stop working, and control the speed of the blower to decrease at a first preset rate.

[0075] According to some embodiments of the present invention, during the process of controlling the speeds of the heater and the blower, the control module 120 is further used to, if the temperature in the cavity is lower than the preset lower temperature limit threshold, control the heater to start working, and control the speed of the blower to increase at a second preset rate.

[0076] According to some other embodiments of the present invention, when the temperature inside the cavity exceeds the upper temperature threshold, the control module 120 controls the heater and the fan speed of the food processing device, specifically for: controlling the operating power of the heater to decrease at a first rate, and controlling the fan speed to decrease at a third preset rate.

[0077] According to some embodiments of the present invention, during the process of controlling the heater and the fan speed, the control module 120 is further configured to: if the temperature inside the cavity is lower than the preset lower temperature threshold, control the operating power of the heater to increase at a second rate, and control the fan speed to increase at a fourth preset rate.

[0078] According to some embodiments of the present invention, the control module 120 is further configured to: respond to a control instruction, and determine the target working time of the food processing device according to the control instruction; when the working time of the food processing device reaches the target working time, control the heater to stop working, and control the fan to operate at a preset speed.

[0079] According to some embodiments of the present invention, when controlling the fan to operate at a preset speed, the control module 120 is further configured to: when the temperature inside the cavity is less than or equal to the first preset temperature and lasts for the first preset time, control the fan to stop working.

[0080] Taking the food processing device as an air fryer as an example, when the user uses the air fryer, the working mode is selected through the display panel (or mechanical buttons) of the air fryer. Among them, when the air fryer is equipped with a mute button, it is also necessary to determine whether the user presses the mute button before implementing the noise reduction strategy of this application; when the air fryer is not equipped with a mute button, the noise reduction strategy is executed by default. When the user presses the start working button, the main control board of the air fryer controls the relay of the heating plate to conduct (that is, the heater starts to work), and at the same time drives the fan to start, and blows the heat of the heating plate to the food in the pot through the fan. The temperature inside the cavity of the food processing device is collected in real time by a temperature sensor arranged in the food processing device. The temperature inside the cavity refers to the temperature of the cavity in the food processing device, and then how to control the heater and the fan is determined according to the size of the temperature inside the cavity.

[0081] For example, when the temperature inside the cavity exceeds the upper temperature threshold and lasts for a certain period of time (such as 10 s), it is considered that the current temperature inside the cavity is too high, and the corresponding fan speed is also relatively high. At this time, the operating power of the heating plate can be controlled to decrease, or the heating plate can be directly turned off, and at the same time the fan speed is decreased to achieve the purpose of reducing noise. Another example is that when the temperature inside the cavity is lower than the lower temperature threshold and lasts for a certain period of time (such as 10 s), it is considered that the current temperature inside the cavity is too low, which will affect the cooking effect. The heating plate can be controlled to start working, or the operating power of the heating plate can be increased, and at the same time the fan speed is gradually controlled to increase, so that the temperature inside the cavity rises more evenly and the cooking effect is guaranteed.

[0082] When the target working time is reached during working hours, first control the heater to stop working, and then control the blower to operate at a preset speed (low speed) to prevent the temperature inside the cavity from dropping too quickly, which may affect the cooking effect. Also, continuously obtain the temperature inside the cavity in real time. When the temperature inside the cavity is less than or equal to the first preset temperature and lasts for the first preset time, control the blower to stop working and enter the standby state.

[0083] It should be noted that for the details not disclosed in the noise reduction device of the food processing device according to the embodiments of the present invention, please refer to the details disclosed in the noise reduction method of the food processing device according to the embodiments of the present invention, and will not be elaborated herein.

Thus, during the operation of the food processing device, the device can continuously obtain the temperature inside the cavity in real time, and when the temperature inside the cavity exceeds a certain value, control the heater and the blower speed to reduce the operating noise of the device and improve the user experience.
