[0053] Embodiment one

[0054] Figure 1 is a flow chart of a noise display method according to the first embodiment of the present application. The present embodiment can be applicable to the case of displaying the noise of a range hood in real time. The method can be executed by a noise display device, which can be realized in the form of hardware and / or software. The noise display device can be configured in an electronic device such as a range hood, a computer, a server or a tablet computer. Specifically, referring to Figure 1 , the method specifically includes the following steps:

[0055] Step 110, obtaining at least one back pressure value of a target range hood, and determining a first noise value corresponding to each back pressure value, respectively.

[0056] Wherein, the back pressure refers to the pressure at the rear end of the range hood, which can be used to describe the pressure of the fluid discharged by the range hood at the outlet or the secondary side in the opposite direction of the flow. In general, the back pressure value is greater than the local atmospheric pressure.

[0057] The target range hood in the embodiment can be any range hood, which can be installed in any household kitchen, kitchen electrical laboratory or restaurant kitchen, and the like, and is not limited in the embodiment.

[0058] In an optional implementation of the embodiment, at least one back pressure value of the target range hood can be continuously acquired, for example, 1, 5, 10, or 15, and the like, which is not limited in the embodiment. Further, a noise value corresponding to each back pressure value can be sequentially determined, and the noise value corresponding to the back pressure value in the embodiment is referred to as a first noise value, which is not limited in the embodiment.

[0059] Optionally, in the embodiment, acquiring at least one back pressure value of the target range hood and determining a first noise value corresponding to each back pressure value can include: obtaining a target back pressure value generated in the working process of the range hood by a back pressure monitoring device installed in the target range hood; determining a target air volume corresponding to the target back pressure value, determining a target noise value corresponding to the target air volume; and determining the target noise value as the first noise value.

[0060] It should be noted that in the embodiment, the back pressure monitoring device can be installed in the target range hood, and the back pressure value of the target range hood can be monitored in real time by the back pressure monitoring device; in the embodiment, the back pressure value can be monitored every interval of a set time in the working process of the target range hood, for example, the back pressure value of the target range hood can be monitored every one second, five seconds, or one minute, ten minutes, and after the back pressure values are monitored, a first noise value corresponding to each back pressure value can be determined.

[0061] In the embodiment, the target back pressure value can be any back pressure value monitored, which is not limited in the embodiment.

[0062] In an optional implementation of the embodiment, after the target back pressure value is determined, a target air volume corresponding to the target back pressure value can be further determined, and then a target air volume corresponding to the target back pressure value is determined; further, a target noise value corresponding to the target air volume is determined, and the target noise value is the first noise value corresponding to the target back pressure value in the embodiment.

[0063] Optionally, in the embodiment, the back pressure-air volume curve and the air volume-noise curve can be determined in advance. It can be understood that, in the embodiment, the back pressure-air volume curve is a performance curve, which can be drawn according to the measured relationship between the back pressure and the air volume. The back pressure-air volume curve can also be determined from the relevant description file of the target range hood, which is not limited in the embodiment. In the embodiment, a plurality of air volume-noise values can be obtained through experiments, and the air volume-noise curve can be fitted according to the air volume-noise values. In the fitted air volume-noise curve, the abscissa can represent the air volume, and the ordinate can represent the noise.

[0064] Further, in the embodiment, after the back pressure-air volume curve and the air volume-noise curve are determined, the target back pressure value can be determined in the back pressure-air volume curve, and the target air volume corresponding to the target back pressure value can be determined. The target air volume can be determined in the air volume-noise curve, and the target noise value corresponding to the target air volume can be determined.

[0065] Optionally, in the embodiment, after the target back pressure value is monitored, the target back pressure value can be substituted into the back pressure-air volume curve to determine the target air volume corresponding to the target back pressure value. Further, the target air volume can be substituted into the air volume-noise curve to determine the target noise value corresponding to the target air volume.

[0066] In step 120, at least one input current of the target range hood is obtained, and a second noise value corresponding to each input current is determined.

[0067] In the embodiment, the second noise value refers to a noise value matched with the input current of the target range hood, which can be any value, and is not limited in the embodiment.

[0068] In an optional implementation manner of the embodiment, a current monitoring device can also be installed in the target range hood. The input current of the target range hood can be monitored in real time through the current monitoring device. It should be noted that the current input current monitored by the current monitoring device can be any current value, which is not limited in the embodiment.

[0069] Optionally, in the embodiment, at least one input current of the target range hood can be continuously obtained, for example, 5, 10 or 15, etc., which is not limited in the embodiment. Further, a second noise value corresponding to each input current can be determined.

[0070] In an optional implementation of the embodiment, the acquiring the at least one input current of the target range hood and determining the second noise value corresponding to each input current can include: acquiring a target input current and determining a target rotating speed of the fan system of the target range hood corresponding to the target input current; determining a target air volume corresponding to the target rotating speed and determining the second noise value corresponding to the target air volume according to the air volume-noise curve.

[0071] Optionally, in the embodiment, after the at least one input current of the target range hood is acquired, the target rotating speed of the fan system of the target range hood corresponding to each input current can be further determined.

[0072] In an optional implementation of the embodiment, the target rotating speed of the fan system of the target range hood can be determined according to the target input current, the torque of the fan system, the voltage of the fan system and the efficiency of the fan system. The target input current can be any one of the acquired input currents, which is not limited in the embodiment.

[0073] The torque of the fan system, the voltage of the fan system and the efficiency of the fan system can be determined by the instruction manual of the target range hood. For example, when the current working gear of the fan system is the middle gear, the torque of the fan system, the voltage of the fan system and the efficiency of the fan system corresponding to the middle gear can be determined by consulting the instruction manual of the target range hood, so that the parameters of the fan system can be quickly and accurately determined.

[0074] Optionally, in the embodiment, the target rotating speed of the fan system of the target range hood can be determined according to the following formula:

[0075]

[0076] In the formula, N is the rotating speed of the fan system, i.e., the target rotating speed in the embodiment; T is the torque of the fan system, I is the input current of the fan system, i.e., the target input current in the embodiment, U is the voltage of the fan system, and β is the efficiency of the fan system.

[0077] It can be understood that according to the above formula, after the target input current of the target range hood is acquired and the torque of the fan system, the voltage of the fan system and the efficiency of the fan system are determined by consulting the instruction manual of the target range hood, the target rotating speed of the fan system of the target range hood can be accurately determined.

[0078] In an optional implementation of the embodiment, after the target rotating speed of the fan system of the target range hood is determined, a target air volume corresponding to the target rotating speed can be determined according to the determined target rotating speed. Further, a current noise value corresponding to the target air volume can be determined according to the preset air volume-noise curve. It should be noted that the air volume-noise curve referred to in the embodiment is a "air volume-noise" curve. For example, the abscissa of the preset air volume-noise curve represents the air volume, and the ordinate represents the noise.

[0079] Optionally, in the embodiment, after the target rotating speed of the fan system of the target range hood is determined, the target air volume can be determined according to the relationship between the rotating speed and the air volume. In the embodiment, the rotating speed and the air volume are positively correlated, that is, the greater the rotating speed of the fan system, the greater the air volume generated, and the smaller the rotating speed of the fan system, the smaller the air volume generated.

[0080] In an example of the embodiment, the target air volume corresponding to the target rotating speed can be determined by the following relationship: In the embodiment, the fan outlet average wind speed can be determined by querying the manual of the target range hood.

[0081] In the embodiment, the target air volume corresponding to the target rotating speed can also be determined by other manners, which will not be described one by one in the embodiment and is not a limitation on the embodiment.

[0082] Optionally, in the embodiment, after the target air volume corresponding to the target rotating speed is determined, the noise value corresponding to the target air volume in the preset air volume-noise curve can be queried, and the noise value is determined as the second noise value.

[0083] In the embodiment, the target air volume corresponding to the target rotating speed can also be determined by other manners, which will not be described one by one in the embodiment and is not a limitation on the embodiment.

[0084] In an optional implementation of the embodiment, after the first noise values and the second noise values are determined, whether the first noise values and the second noise values satisfy the preset limit condition can be determined in sequence. The preset limit condition can be an inequality condition, for example, whether the difference between the matching first noise value and the second noise value is less than a limit value. The matching first noise value and the second noise value can be the first noise value corresponding to the back pressure value collected at the same time and the second noise value corresponding to the input current, and the limit value can be a fixed value, for example, 1 dB, 2 dB, or 3 dB, which is not limited in the embodiment.

[0085] In an optional implementation of the embodiment, in a case where it is determined that the first noise values and the second noise values satisfy the preset limit condition, a display noise value corresponding to the first noise values and the second noise values can be further determined, and the display noise value can be displayed in real time on the noise display panel of the target range hood.

[0086] The display noise value can be the average of the first noise values and the second noise values. In the embodiment, the average or the median of the first noise values can be determined first, and the average or the median is determined as a target first noise value. Then, the average or the median of the second noise values can be determined, and the average or the median is determined as a target second noise value. Further, the calculation result of (target first noise value+target second noise value) / 2 is determined as the display noise value, and the display noise value is displayed in real time on the noise display panel of the target range hood.

[0087] The technical solution of the embodiment acquires at least one back pressure value of a target range hood, and determines a first noise value corresponding to each back pressure value. At least one input current of the target range hood is acquired, and a second noise value corresponding to each input current is determined. In a case where it is determined that the first noise values and the second noise values satisfy the preset limit condition, a display noise value corresponding to the first noise values and the second noise values is determined, and the display noise value is displayed in real time on the noise display panel of the target range hood. The problem that it is difficult to determine and display in real time the noise of the range hood is solved, the noise of the range hood is determined and displayed in real time, and the use experience of the user is improved.
