Description

Technical Field

[0001] The present invention relates to a control method for an integrated range hood, and particularly to a control method for a blower of an integrated range hood. Background Art

[0002] An integrated range hood is a kitchen appliance integrating multiple functions, and has the advantages of saving space, good fume extraction effect, energy saving, low consumption and environmental protection. With the fast-paced life, people are increasingly relying on the multi-functional and intelligent working mode of the integrated range hood.

[0003] However, when the existing integrated range hood is in use, the user manually adjusts the exhaust air volume of the blower according to the fume volume in the kitchen during use. In fact, the fume suction capacity of the blower is not only related to its blower power, but also related to the air outlet resistance of the blower. For example, during the peak and non-peak periods of the user's cooking, the resistance of the common flue between floors varies greatly, resulting in the fact that although the blower is in the same exhaust air gear, its fume suction capacity is not the same. When the user is using it, he cannot feel the change of the fume resistance, resulting in a large difference in the fume suction capacity of the integrated range hood in different use environments and use periods. Summary of the Invention

[0004] In view of the defects in the prior art that the fume suction capacity of the integrated range hood varies greatly in different use environments and use periods, the present invention provides a new control method for a blower of an integrated range hood.

[0005] In order to solve the above technical problems, the present invention is realized through the following technical solutions:

[0006] A control method for a blower of an integrated range hood, including a power supply board, a blower, and an integrated range hood head. An air inlet is provided on the integrated range hood head, the air inlet is communicated with the blower, the blower is connected to the power supply board, a wind speed sensor is further provided in the air inlet, the wind speed sensor is connected to the power supply board, the power supply board is provided with a flow velocity threshold V0, and the method further includes the following steps:

[0007] S1. Turn on the blower and wait for a time T1, and then obtain the current rotational speed of the blower as the initial rotational speed N1;

[0008] S2. Detect the air flow velocity at the air inlet of the integrated range hood head and define it as V1, and define the first adjusted rotational speed as N2. If V1 < V0, jump to step S21; if V0 ≤ V1 ≤ V0 + 0.5 m / s, jump to step S22; if V1 > V0 + 0.5 m / s, jump to step S23;

[0009] S21. Adjust the rotational speed of the blower according to the formula N2 = N1 + 20 r / min to obtain the first adjusted rotational speed N2, and then jump to step S3;

[0010] S22. Adjust the rotational speed of the fan according to the formula N2 = N1 to obtain the first adjusted rotational speed N2, thereby completing the adjustment of the fan;

[0011] S23. Adjust the rotational speed of the fan according to the formula N2 = N1 - 20 r / min to obtain the first adjusted rotational speed N2, and then jump to step S3;

[0012] S3. Detect the air flow velocity V2 at the air inlet of the head of the integrated range hood, and define the second adjusted rotational speed as N3. If V2 < V0, jump to step S31; if V0 ≤ V2 ≤ V0 + 0.5 m / s, jump to step S32; if V2 > V0 + 0.5 m / s, jump to step S33;

[0013] S31. Adjust the rotational speed of the fan according to the formula N3 = N2 + 10 r / min to obtain the second adjusted rotational speed N3, and then jump to step S4;

[0014] S32. Adjust the rotational speed of the fan according to the formula N3 = N2 to obtain the second adjusted rotational speed N3, thereby completing the adjustment of the fan;

[0015] S33. Adjust the rotational speed of the fan according to the formula N3 = N2 - 10 to obtain the second adjusted rotational speed N3, and then jump to step S4;

[0016] S4. Detect the air flow velocity V3 at the air inlet of the head of the integrated range hood, and define the third adjusted rotational speed as N4. If V3 < V0, jump to step S41; if V0 ≤ V3 ≤ V0 + 0.5 m / s, jump to step S42; if V3 > V0 + 0.5 m / s, jump to step S43;

[0017] S41. Adjust the rotational speed of the fan according to the formula N4 = N3 + 5 r / min to obtain the third adjusted rotational speed N4, thereby completing the adjustment of the fan;

[0018] S42. Adjust the rotational speed of the fan according to the formula N4 = N3 to obtain the third adjusted rotational speed N4, thereby completing the adjustment of the fan;

[0019] S43. Adjust the rotational speed of the fan according to the formula N4 = N3 - 5 r / min to obtain the third adjusted rotational speed N4, thereby completing the adjustment of the fan.

[0020] Through the above method, the fan can adjust its own rotational speed according to the air flow velocity at the air inlet of the head of the integrated range hood, thereby better ensuring the oil fume suction capacity in different usage environments and usage periods.

[0021] Preferably, in the above-mentioned integrated range hood fan control method, V0 is 4.2 m / s.

[0022] The flow velocity threshold V0 is set within the above range, which has a better regulation reference and a wider application range.

[0023] Preferably, in the integrated range hood fan control method described above, T1 is 4 to 5 seconds.

[0024] Setting T1 to the above time can give the fan a relatively generous stable time and reduce errors. BRIEF DESCRIPTION OF THE DRAWINGS
