Embodiment 1
[0065] Such as Figure 1 to Figure 7 As shown, the shielding air curtain includes a first air curtain 1110' and a second air curtain 1120' intersecting in the moving direction of the shielding air curtain. The shielding air curtain in this embodiment is composed of two parts. Both the first air curtain 1110' and the second air curtain 1120' can independently provide a certain shielding effect for the diffusion of oil smoke. Oil fume shielding air curtain. The relative distance between the first air curtain 1110' and the second air curtain 1120' in this embodiment is relatively far at the position near the air outlet of the air curtain device, and at this position, the shielding air curtain is in the direction of its movement. superior( figure 2 The section shown below) has a larger cross-sectional size, and the flow direction of the air curtain airflow at this position is better, which can have a good shielding effect on oil fumes. In actual use, compared with the oil fume...
Embodiment 2
[0068] Such as Figure 1 to Figure 7 As shown, the difference between the air curtain range hood described in this embodiment and the above embodiments lies in the angle between the central axis of the first air curtain 1110' and the central axis of the second air curtain 1120' is the shielding angle α'. The equipment / user can adjust the air supply distance of the shielding air curtain by adjusting the shielding angle α'. When the shielding angle α' is larger, the air supply distance of the shielding air curtain is larger, and when the shielding angle α' is smaller, the air supply distance of the shielding air curtain is smaller. Preferably, the shielding angle α' is an acute angle. When adjusting the shielding angle α', the device / user can specifically adjust only the wind outlet angle of the first air curtain 1110' / second air curtain 1120', or adjust the angle of the first air curtain 1110' and the second air curtain 1110'. The two air curtains 1120' are adjusted accordin...
Embodiment 3
[0072] Such as Figure 4 As shown, the difference between the air curtain range hood described in this embodiment and the above embodiments is that the air curtain device includes a first air curtain device 11' for generating the first air curtain 1110' and a The second air curtain device 12' of the second air curtain 1120' is generated. The number of air curtain devices in this embodiment is two, which are respectively used to generate different parts of the shielding air curtain. Then, in actual use, since the air curtain is jointly generated by two air curtain devices, the equipment / user can control the different air curtain devices separately, such as adjusting the air supply direction and the air supply volume respectively.
[0073] Further, as Figure 5 As shown, the first air curtain device 11' in this embodiment is arranged between the second air curtain device 12' and the user, and the first air curtain device 11' faces away from the range hood The direction protru...
