Problems solved by technology

For example, the Chinese patent application with the application number CN201410673521.3 discloses a range hood with double air inlets. When only one burner is used, two air inlets are opened at the same time, which will cause waste of resources
However, for range hoods with a single air inlet, since the fans in the range hood are fixed, and in the case of a single stove, usually there will be a high concentration of oil fume on one side and a low concentration of oil fume on the other side of the cooker. Unbalanced oil fume concentration formed above
The position of the fan of this range hood cannot be dynamically adjusted according to the oil fume on both sides. When the concentration of oil fume on the left and right sides of the range hood is different, there will be a risk of oil fume escaping. At this time, the only way to increase the operating gear of the fan , to ensure the smoking effect, the existing range hoods cannot maximize the performance of the fan, and the energy consumption is high

Embodiment Construction

[0043] The present invention will be further described in detail below with reference to the embodiments of the accompanying drawings.

[0044] see Figure 1-Figure 7 A range hood includes a casing 10, a fan 20, a driving device 30, a guide rail support assembly, a range hood detection device, a distance sensor 50, a temperature sensor 60 and a controller (not shown). The fan 20 , the driving device 30 and the guide rail support assembly are all arranged in the casing 10 .

[0045] see figure 1 , the casing 10 includes a fan support 15 and a box body 11 connected to the bottom of the fan support 15. The front part of the box body 11 has a panel 110 with a lateral opening. The upper edge is also provided with a smoke baffle 111 which can open and cover the transverse opening.

[0046] see figure 1 and Image 6 , the casing 10 has an air suction port 101 on the bottom panel 110 (that is, the above-mentioned lateral opening), an air exhaust port 102 and a smoke exhaust chann...

Abstract

The invention relates to a range hood. The range hood comprises a machine shell, a fan, a driving device, an oil fume concentration detection device and a controller. The machine shell is provided with an air suction port. The fan is movably arranged in the machine shell. The driving device is arranged in the machine shell, and the power output end of the driving device is connected with the fan. The oil fume concentration detection device is arranged on the machine shell and is used for detecting the oil fume concentrations of the left side and the right side of the range hood. The controller is in electric signal connection with the driving device, the fan and an oil fume concentration sensor, and therefore the driving device can be controlled to act according to the oil fume concentrations, obtained by the oil fume concentration detection device, of the left side and the right side of the range hood, and the fan is driven to move left and right in the machine shell. According to the range hood, the problem of oil fume escape is effectively solved, maximum utilization of the fan is guaranteed, and the oil fume suction effect is improved. The invention further relates to a control method of the range hood.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to a range hood and a control method for the range hood. Background technique [0002] The cooker usually has two stove eyes (burners), and the existing range hood also has a single air inlet range hood and a double air inlet range hood. For example, the Chinese patent application with the application number CN201410673521.3 discloses a dual-air inlet range hood, but in actual use, only one pot is often used for cooking, and there are generally two burners on the stove. When only one burner is used, two air inlets are opened at the same time, which will cause waste of resources. However, for a range hood with a single air inlet, since the fans in the range hood are all fixed, in the case of a single stove, there is usually a high concentration of oil fume on one side and a low concentration of oil fume on the other side. An unbalanced concentration of soot is formed above. Th...
