Description

Range hood with lift air outlet

The invention relates to a range hood with an air suction port that can be raised and lowered, so that the operator can adjust the distance between the air suction port and the stovetop according to different usage conditions.

Generally speaking, the range hood is a very important device for the kitchen. Since most ingredients are prone to produce a lot of oil fumes during cooking, such as quick frying, frying, frying, etc., the inhalation of oil fumes to the human body will cause health damage. In addition, after the fume is dispersed, it is easy to stick to the indoor environment, contaminate clothes and household items.

In view of the foregoing content, we can know the importance of range hoods, but the distance between the exhaust position and the stovetop of the range hoods currently on the market is fixed, for example, Taiwan Patent No. As shown, such a conventional range hood has a disadvantage. If the distance between the range hood and the stovetop is designed too far, when the height of the cooking tool is low, the air extraction position will be too far away from the cooking utensils, resulting in soot. The suction power of the cooker cannot be effectively exerted, but if the design distance between the two is too close, when the cooking utensils are high, the ventilation position of the range hood and the cooking utensils are too close, and the operating space for cooking will be lost.

In view of the foregoing, it can be seen that the conventional range hoods are not well adapted to all cooking types in terms of extracting oil fume. Therefore, range hoods with air vents that can be raised and lowered have been introduced on the market. For example, Taiwan Patent No. M604382 "has In this case, the range hood of the lifting duct module is driven by a rack and a gear, so that the lifting duct module can be raised and lowered to achieve the effect of adjusting the suction position. However, this structure has The big disadvantage is that the drive lifting structure of the rack and gear is easy to make the lifting air duct module skew to one side during the lifting process, thereby affecting the smoothness of the lifting.

The invention utilizes the combination of the lifting body and the lifting unit to achieve the purpose of raising and lowering the air suction port, so that the user can adjust the distance between the air suction port and the position where the oil fume is generated according to different conditions such as the height of the cooking utensils, the cooking form, etc. The efficiency of extracting oil fume is optimized, and the lifting body is connected to the main body by means of rails and sliding parts, so that the lifting process is smoother than the conventional lifting structure.

The fan 60 can extract oil fume through the suction channel 320 ; an induction label 70 is disposed on the lifting body 30 ; and a height detector 80 is used to detect the induction label 70 and is disposed in the accommodating channel 110 And corresponding to the position of the sensing label 70 , the height detector 80 is electrically connected to the control panel 20 , and the wind speed adjustment module 210 can automatically adjust the rotation speed of the exhaust fan 60 according to the signal feedback of the height detector 80 .

Compared with the previous embodiment, this embodiment adds the function of automatically adjusting the wind speed, and in order to achieve this function, the height detector 80 is used together with the sensor tag 70 and the wind speed adjustment module 210 to achieve, such as the tenth figure, As shown in the eleventh figure, the sensing label 70 is disposed on the lifting body 30 , and the sensing label 70 will rise and fall along with the lifting and lowering of the lifting body 30 , so the wind speed adjustment module 210 can use the height detector 80 to detect The measured position signal of the sensor tag 70 is used to determine the lifting range of the lifting body 30, and to calculate the current rotation speed signal to be given to the exhaust fan 60 to improve the efficiency of extracting oil fume.

Further, as shown in Figures 10 and 11, the lift unit 40 includes a slider 410, a driver 420, and a screw 430. The driver 420 is disposed in the accommodating passage 110 and connected to the The frame 50 and the screw 430 are assembled on the driver 420 , the slider 410 has a screw hole 4110 , the slider 410 is movably arranged on the screw 430 by the screw hole 4110 , and one side of the slider 410 connected to the lift body 30 .

Further, as shown in FIG. 9 , the lifting body 30 is provided with a plurality of side air ports 340 connected to the air suction channel 320 on the peripheral side. The advantage of this structure is that the range of oil fume suction can be improved.

It further includes a smoke detection module 90, as shown in the eighth, tenth and eleventh figures, which is disposed at the position of the lifting body 30 close to the air suction port 330 and is electrically connected with the wind speed adjustment module 210. The wind speed adjustment The module 210 can change the rotation speed of the exhaust fan 60 according to the oil fume concentration signal sent by the smoke detection module 90 . Avoid unnecessary high speed of the exhaust fan 60, thereby reducing noise and electricity bills.

Further, the ratio of the bottom area of the main body 10 to the bottom area of the lifting body 30 is three to one. This ratio can most effectively present the effect of absorbing oil fume, and can prevent the lifting body 30 from being too large, which in turn leads to excessive weight, which leads to the lift Group 40 load is too high.

The wind speed adjustment module 210 is preset with three rotation speed adjustments: low rotation speed, medium rotation speed and high rotation speed. When the lifting body 30 is lowered by 0-7 cm from the highest position, the wind speed adjustment module 210 is sent to the exhaust fan 60. The control signal is a low speed. When the lift body 30 is lowered by 7-15 cm from the highest position, the control signal sent by the wind speed adjustment module 210 to the exhaust fan 60 is a medium speed. When the lift body 30 is lowered from the highest position by 15 cm When it is about 25 cm, the control signal sent by the wind speed adjustment module 210 to the exhaust fan 60 is a low rotation speed, which shows that the lower the lifting body 30 is lowered, the faster the rotation speed of the exhaust fan 60 is, and the higher the lifting body 30 rises. The rotation speed control method is that the lower the rotation speed of the exhaust fan 60 is, the purpose of this rotation speed control is that the lifting body 30 can be lowered and the high rotation speed of the exhaust fan 60 can quickly extract the oil fume, so that the lifting body 30 can be quickly extracted when the oil fume needs to be sucked urgently. When descending, the exhaust fan 60 automatically switches to a high speed, so as to quickly absorb the oil fume in the first time to avoid spreading, and the higher the lifting body 30 rises, it means that the user does not need too strong oil fume absorption ability, so the speed of the exhaust fan 60 is automatically switched to Low speed is more power saving and noise reduction.
