Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning type range hoods, and in particular to an automatic air suction control method and system based on wind pressure difference. Background Art

[0002] In the existing air-conditioning range hood, a purification chamber and a condensation plate are arranged in sequence below the suction fan. The oil fume passing through the condensation plate will liquefy the oil stains and adhere to the interception device, and the cooled smoke will pass through the purification chamber and be drawn out of the purification chamber by the suction fan and discharged into the room to form an air circulation, which can not only eliminate the oil fume pollution but also circulate the cooled and filtered smoke in the room to achieve the effect of air conditioning cooling.

[0003] However, in the existing air-conditioning type range hood, multiple filter layers are used in the purification chamber to perform secondary purification of the flue gas. After long-term use, a large amount of particulate pollutants will be attached to the filter layer, causing blockage of the air duct. Different degrees of blockage will affect the actual suction intensity of the range hood. If the suction power before blockage is maintained, the current suction intensity will not be able to achieve the purpose of purifying the oil fume when the air duct is blocked. The condensation temperature of the condensation plate serves as the regulating hub for condensing and liquefying the oil fume. If the condensation temperature is not enough, the oil fume will be completely liquefied, which will also cause blockage of the range hood, thereby indirectly affecting the regulation of the suction intensity.

[0004] Therefore, there is an urgent need for an automatic air suction control system based on wind pressure difference to solve the problem of maintaining the air suction intensity of the air-conditioning type range hood under different degrees of blockage in the air duct.

[0066] It should be noted that the air-conditioning range hood is a new type of range hood that integrates air-conditioning and range hood functions. Its main feature is that the oil fume below is sucked into the purification chamber through a suction fan, and a condensation plate is provided at the air inlet of the purification chamber to liquefy the oil fume and then attach it to the interception device to collect the oil. Some of the oil fume that is not completely liquefied will enter the purification chamber and pass through the layers of filter layers to further purify the oil in the flue gas, and the flue gas cooled by the condensation plate can be discharged from the smoke outlet of the purification chamber. Without the need for a pipeline design for the range hood, it can not only solve the oil fume purification problem, but also achieve the effect of adjusting the indoor temperature by air conditioning.

[0067] Furthermore, the air-conditioning type range hood currently still has the problem of unstable suction effect during the oil fume purification process. The direct reason affecting the suction control is that the filter layer is easily clogged by oil, thereby changing the wind pressure difference in the purification chamber. Specifically, when the same suction power is used, if the filter layer is clogged, the suction intensity before clogging cannot be achieved, thereby affecting the effect of oil fume purification. On the other hand, in addition to affecting the ambient temperature of the air-conditioning output, the condensation temperature of the condensation plate will indirectly affect the adhesion rate of oil outside the purification chamber, thereby causing the adhesion rate of oil on the filter layer to increase, thereby causing more oil clogging of the filter layer. The suction power and condensation temperature are dynamic parameters, which need to be dynamically adjusted along with the air-conditioning function and the range hood function. Therefore, the present application proposes an automatic suction control method based on wind pressure difference to solve the problem of suction power adjustment of the air-conditioning type range hood under the dynamic balance of condensation temperature and suction power, reduce the influence of air duct blockage caused by different inducements on the suction intensity, and can dynamically adjust the suction power corresponding to the required suction intensity under different blockage degrees to automatically maintain the effect of the range hood in purifying the flue gas. The detailed implementation method is shown below.

[0068] Example 1

[0069] See also Figure 1 The embodiment of the present invention discloses an automatic air suction control method based on wind pressure difference, comprising:

[0070] 101. Collect historical ambient temperature, condensation temperature and suction power data, and construct a mapping relationship between ambient temperature, condensation temperature and suction power under different condensation temperature systems;

[0071] Specifically, various temperature data can be collected through the temperature sensor, including but not limited to historical ambient temperature, condensation temperature and suction power data. The historical ambient temperature includes the temperature states when the air conditioner is turned on and off. The ambient temperature can reflect the air-conditioning function requirements of the air-conditioned range hood for the condensation temperature, thereby providing data support for the process of selecting the target condensation temperature.

[0072] In an optional embodiment, the collecting of historical ambient temperature, condensation temperature and suction power data, and constructing a mapping relationship between ambient temperature, condensation temperature and suction power under different condensation temperature systems, includes:

[0075] The air suction power data within the temperature range is acquired, a mapping relationship between the basic condensing temperature range and the historical ambient temperature is established, and a mapping relationship between the basic condensing temperature range and the air suction power is established.

[0076] Specifically, with regard to the problem of regulating the temperature of the condensing plate when using air conditioning, different seasonal factors and weather factors will affect the condensing temperature. Therefore, it is necessary to further refine the temperature classification, and then use the range hood under different indoor temperature conditions to output optional target suction powers corresponding to different condensing temperatures.

[0077] Furthermore, in a certain temperature range, the suction power data can be used to reflect the degree of air duct blockage, and the suction power can be used as a data basis and training data set for subsequent determination of the target suction power.

The second wind pressure change rate can reflect the impact of different condensation temperatures on the degree of air duct blockage, and thus the degree to which the suction power needs to be adjusted. It is easy for technicians in this field to know that by obtaining wind pressure difference data, they can calculate the suction power required for the current suction intensity.

[0083] In an optional embodiment, obtaining the temperature change rate under different condensation temperature systems includes:

The above-mentioned different room temperature environments specifically also include weather classification and season classification to cover different usage scenarios.
