Description

Technical Field

[0001] The present invention relates to the technical field of range hoods, and in particular to a method and a control device for the cleaning-free operation of a range hood, and a computer device. Background Art

[0002] Nowadays, range hoods have become a standard feature in kitchens. They are used to discharge the fumes produced during cooking, thereby purifying the indoor air. Ideally, the fume particles produced during cooking will be sucked into the range hood along with the airflow, intercepted and separated by the filter and impeller inside the range hood, and finally flow into the oil cup.

[0003] However, in actual use, due to the high viscosity of the oil in the cooking fume, it is easy to adhere to the impeller and the inner wall of the volute inside the range hood after condensation. If it is not cleaned for a long time, the oil will accumulate on the impeller and the inner wall of the volute to form oil scale or oil film, which reduces the working efficiency of the fan of the range hood and causes the oil fume to escape.

[0004] For this purpose, the industry has developed a type of range hood in which the oil mist interception plate is coaxially installed with the impeller, and the impeller and the interception plate are jointly driven by a motor.

[0031] In order to solve the technical problem of unsatisfactory oil fume interception during the operation of range hoods in the prior art, the present invention provides a cleaning-free operation control method for range hoods, which can maximize the oil fume interception efficiency while ensuring the oil fume extraction efficiency, greatly reduce the oil fume passing through the fan impeller and adhering to the fan impeller to form oil stains and oil film, thereby ensuring the working efficiency of the fan.

[0032] The embodiment of the present invention provides a method for controlling the cleaning-free operation of a range hood, which is applied to the range hood. Figure 1 , Figure 1 : is a schematic diagram of the structure of the range hood provided by the present invention. The range hood comprises an interception plate 3; the motor of the interception plate 3 is independent of the motor of the fan 2, and the interception plate 3 is arranged at the oil smoke inlet. The control method for the no-cleaning operation comprises: Step S110: During the operation of the fan, the speed gear of the fan is obtained in real time.

[0033] Step S120: Determine the required interception speed of the motor of the interception disk according to the speed gear of the fan.

[0034] Step S130, controlling the motor of the interception disk to run at a determined interception rotation speed.

[0035] See also Figure 1The interception plate 3 of the range hood used in the present invention is arranged at the oil fume inlet of the range hood. During the operation of the fan 2, all the oil fume entering the range hood will pass through the interception plate 3. When the motor of the interception plate 3 is started during the operation of the fan 2, the interception plate 3 can intercept the oil fume entering the range hood. During the operation of the fan of the range hood used in the present invention, after starting the motor of the interception plate, it is necessary to control the motor speed of the interception plate. The control of the motor speed of the interception plate 3 should be based on the premise of ensuring the efficiency of oil fume extraction and achieving the maximum interception efficiency of oil fume. In this way, the oil fume passing through the impeller of the fan 2 can be greatly reduced, and the oil film of oil dirt attached to the impeller of the fan 2 can be reduced, thereby ensuring the working efficiency of the fan, and then the no-cleaning effect of the range hood can be achieved.

[0036] In one embodiment, if Figure 3 As shown, the step S120 may include steps S121 to S124.

[0037] Step S121, determining the speed gear type of the fan in real time.

[0038] In this embodiment, the speed gears of the fan include: high speed gear, medium speed gear, and low speed gear. The speed gear of the fan of the range hood can be selected according to the selection instruction input by the user, see Figure 1 The user can select the speed gear by pressing the speed gear selection button in the operation display area 4 of the range hood. Of course, the speed gear selection can also be achieved by inputting a selection command to the range hood through voice input. The speed gear of the fan can also automatically select an adaptive speed gear according to the current size of the oil smoke at the oil smoke inlet. This automatically adaptive speed gear is defined as the cruise gear. See Figure 1 The user can select the cruise gear by pressing the cruise gear selection button in the operation display area 4 in the range hood. When the user selects the cruise gear, the range hood automatically selects the appropriate speed gear according to the size of the oil smoke at the current oil smoke inlet.

[0039] Step S122: When the speed gear type is a high speed gear, determine that the required interception speed of the motor of the interception disk is the interception high speed gear speed.

[0040] In this embodiment, the value range of the fan speed V1 corresponding to the high gear is: 900 rpm < V1 ≤ 1200 rpm; the value range of the motor speed Va of the interceptor disk high gear is: 1200 rpm < Va ≤ 1500 rpm.

[0041] Step S123: When the speed gear type is the medium speed gear, determine that the required interception speed of the motor of the interception disk is the interception medium speed gear speed.

[0042] In this embodiment, the value range of the fan speed V2 corresponding to the medium speed gear is: 600 rpm < V2 ≤ 900 rpm; the value range of the motor speed Vb of the interceptor disk medium speed gear is: 900 rpm < Vb ≤ 1200 rpm.

[0043] Step S124: When the speed gear type is a low speed gear, determine that the required interception speed of the motor of the interception disk is the interception low speed gear speed.

[0044] In this embodiment, the value range of the fan speed V3 corresponding to the low speed gear is: 400 rpm < V3 ≤ 600 rpm, and the value range of the motor speed Vc of the interceptor disk low speed gear is: 600 rpm < Vc ≤ 900 rpm.

[0045] This embodiment controls the motor of the interception disk to run at a speed suitable for the fan during the operation of the fan, so as to maximize the interception efficiency of oil fumes while ensuring the oil fume extraction efficiency of the range hood and environmental protection and energy saving, greatly reduce the oil fume passing through the impeller of the fan 2, and reduce the oil stains and oil film formed on the impeller of the fan 2, thereby ensuring the working efficiency of the fan 2.

[0046] Furthermore, the interception plate in the range hood used in this embodiment is designed to be inclined, that is, the plate surface of the interception plate forms an angle with the horizontal plane, and the angle is generally set to 10° to 30°, preferably 15°. Such a setting can allow the grease on the interception plate to quickly enter the grease storage groove.

[0047] See also Figure 4 In some embodiments, Figure 2 On the basis of the step S110, the step also includes: Step S001, receiving a power-on instruction and starting the fan.

[0048] Step S002: After the first set time, the motor of the interception disk is started to run at the speed of the interception high gear.

[0049] In order to prevent the range hood from resonating or making noise due to coupling, the present embodiment needs to start the interception disk after the range hood fan is running normally, so it is necessary to start the motor of the interception disk after the fan runs for a first set time. The value range of the first set time is: 3 to 5 seconds. In addition, the interception disk may be difficult to start due to oil stains attached, or the atmospheric pressure of the environment causes the load to be present during startup, and high-speed operation is required to ensure successful startup. Therefore, when starting the interception disk in the present embodiment, the interception disk is started at the speed of the high-speed gear.

[0050] Furthermore, in this embodiment, the interception disk rotation speed is controlled by controlling the working current or working voltage of the interception disk motor. The motor of the interception disk can be an AC motor or a DC motor.

[0051] In some embodiments, see Figure 5 ,exist Figure 4 On the basis of the above, the step S002 further includes the following processing: Step S003, recording the current running time of the motor of the interception disk in real time.

[0052] The purpose of calculating the motor running time of the interception disk in this embodiment is to calculate the amount of grease intercepted by the interception disk. Generally speaking, the more fumes there are at the oil fume inlet, the faster the fan speed is, the faster the corresponding speed of the interception disk motor is, and the more grease the interception disk intercepts per unit time. In order to ensure the reliability of the data, it is necessary to define the running time of the interception disk running at different speeds. Assume that the actual running time of the interception disk motor running at the speed of interception high gear is T1; the actual running time of the interception disk motor running at the speed of interception medium gear is T2; the actual running time of the interception disk motor running at the speed of interception low gear is T3. When calculating the running time of the motor of the interception disk, it is necessary to multiply T1, T2, and T3 by the corresponding coefficients K1, K2, and K3 respectively. The current running time of the motor of the interception disk T 本 =K1T1+K2T2+K3T3. Wherein, K1>K2>K3>0. Preferably, K1>K2>K3≥1, for example, K1 can be set to 2; K2 can be set to 1.5; K3 can be set to 1. When K1 is 2, K2 is 1.5, and K3 is 1, then T 本 =K1T1+K2T2+K3T3=2T1+1.5T2+T3.

[0053] See also Figure 5 In this embodiment, after step S130, the following steps are further included: Step S140, receiving a shutdown instruction; Step S150: Calculate the current accumulated running time of the interception disk.

[0054] In this implementation, it is assumed that the current cumulative running time of the interception disk is set to T 当前累加 , the accumulated running time of the interception disk before the range hood is turned on is set to T 之前累加 , then T 当前累加 =T 之前累加 +T 本 =T 之前累加 +2T1+1.5T2+T3.

[0055] This embodiment calculates the current accumulated running time of the interception disk in order to calculate the time for which the interception disk intercepts grease.

[0056] Step S160: When the accumulated running time reaches a second set time, the fan is controlled to stop running.

[0057] In this embodiment, the value of the second set time is set according to whether the amount of grease attached to the interception disk has reached the amount that requires self-cleaning. That is, the amount of grease currently intercepted by the interception disk can be known based on the accumulated running time of the interception disk. When the accumulated running time of the interception disk reaches the second set time, it indicates that the amount of grease currently attached to the interception disk has reached the amount that requires self-cleaning. At this time, it is necessary to control the interception disk to perform self-cleaning operations to achieve the effect of regularly cleaning the interception disk, and further realize the no-cleaning effect of the range hood. Generally, the value range of the second set time is 300 minutes to 600 minutes. For example, it can be set to 300 minutes, 360 minutes, 420 minutes, 480 minutes, 540 minutes, or 600 minutes.

[0058] Step S170, controlling the motor of the interception disk to run at the interception high gear speed for a third set time to achieve self-cleaning of the interception disk.

[0059] After the fan stops running, this step controls the motor of the interception disk to run at the interception high-speed gear speed for the third set time. The purpose is to use the centrifugal force through high-speed rotation to move the grease attached to the interception disk itself to the outer ring of the interception disk, and finally collect it in the grease collection groove, thereby achieving self-cleaning of the interception disk. The value of the third set time is based on the purpose of achieving self-cleaning of the interception disk. Generally, the value range of the third set time is set to: 90 seconds to 120 seconds. For example, it can be set to 90 seconds, 100 seconds, 110 seconds, or 120 seconds.

[0060] Further, in some embodiments, after the interceptor disc performs the self-cleaning operation, the range hood resets the interceptor disc accumulated running time to zero, wherein the current accumulated running time refers to the accumulated running time of the interceptor disc after the previous accumulated running time of the interceptor disc is reset to zero.

[0061] Step S180: Control the range hood to perform a shutdown operation.

[0062] See also Figure 6 In some embodiments, Figure 5 On the basis of the step S180, the step also includes: Step S190: Generate and issue an oil pouring reminder message.

[0063] As the accumulated running time of the interception disk increases, the grease in the grease storage tank corresponding to the interception disk will gradually increase. Therefore, it is necessary to remind the user to pour out the oil in time after the accumulated running time of the interception disk reaches a certain value, such as the second set time, so as to leave storage space for the grease intercepted during subsequent operation.

[0064] The oil pouring reminder information in this embodiment can be issued by voice, by text display, or by voice plus text display.

[0065] See also Figure 7 In some embodiments, Figure 6 On the basis of the step S150, the step also includes: Step S200, controlling the fan to run at a low speed and the motor of the interceptor disk to run at the interception low speed for a third set time.

[0066] In this embodiment, after receiving the shutdown command, the fan runs at a low speed and the motor of the interception disk runs at the interception low speed for a third set time, so as to remove the oil smoke in the environment where the range hood is located, ensuring that the air in the environment is fresh after the range hood is turned off.

[0067] See also Figure 8 In some embodiments, Figure 7 On the basis of the step S150, the method further includes: when the accumulated running time does not reach the second set time, proceeding to step S180.

[0068] In this embodiment, when the accumulated operating time of the interception disk does not reach the second set time, it means that the interception disk has not reached the time for self-cleaning. At this time, it is only necessary to directly transfer to step S180 to control the range hood to perform the shutdown operation.

[0069] See also Fig. 9 In some embodiments, Figure 6 On the basis of the step S150, the following steps are further included: Step S210: When the accumulated running time does not reach the second set time, control the fan to run at a low speed and the motor of the interception disk to run at the interception low speed for a third set time; then proceed to step S180.

[0070] In this embodiment, after calculating the current accumulated running time of the interception disk, when the accumulated running time has not reached the second set time, the fan runs at a low speed and the motor of the interception disk runs at the interception low speed for a third set time, and then the range hood is controlled to perform a shutdown operation. This can clear the fumes in the environment where the range hood is located before the range hood is turned off, ensuring that the air in the environment is fresh after the range hood is turned off.

[0071] See also Fig.10 In some embodiments, Figure 4 On the basis of the step S130, the following steps are further included: Step S220, receiving a shutdown command, controlling the fan to run at a low speed, and the motor of the interceptor disk to run at an interception low speed for a third set time.

[0072] In this embodiment, after receiving the shutdown command, the fan runs at a low speed and the motor of the interception disk runs at the interception low speed for a third set time, so as to remove the oil smoke in the environment where the range hood is located, ensuring that the air in the environment is fresh after the range hood is turned off.

[0073] Step S230: controlling the range hood to perform a shutdown operation.
