Embodiment 1

[0052] Such as Figure 1 to Figure 9 As shown, in the air curtain range hood described in this embodiment, the air curtain device includes a shielding air curtain unit 111 that generates a shielding air curtain 1110, and a blocking air curtain unit 112 that generates a blocking air curtain 1120. The blocking air curtain 1120 and the shielding air curtain 1110 intersect in their moving directions, thereby controlling the effective distance of the airflow of the shielding air curtain. Since the air curtain airflow is only affected by air resistance during operation, it can be approximately regarded as running in a straight line before encountering other resistances. At the intersection position of the shielding air curtain and the blocking air curtain, the airflows of the two meet, and the distance between the two gradually decreases in the air path before the intersection (from the air outlet to the intersection position). In this section of the air curtain, Since the airflow ...

Embodiment 2

[0056] Such as Figure 1 to Figure 9 As shown, the difference between the air curtain range hood described in this embodiment and the above embodiment is that: the airflow direction of the blocking air curtain 1120 and the air suction direction of the air curtain range hood ( figure 1 In the vertical upward direction, correspondingly, the direction of the air suction port is vertically downward) and there is a certain angle between them. Ensure that the blocking air curtain can intersect with the shielding air curtain after running to a certain distance, and then disperse the shielding air curtain at the intersection position to control the effective distance of the shielding air curtain. Preferably, the airflow direction of the blocking air curtain refers to: the airflow direction of the blocking air curtain / the direction of the central axis of the blocking air curtain at the air outlet of the blocking air curtain unit. Preferably, the included angle ranges from 100° to 180°...

Embodiment 3

[0060] Such as Figure 1 to Figure 9 As shown, the difference between the air curtain range hood described in this embodiment and the above embodiment is that the air curtain range hood includes a housing 2 constituting its outer contour, and the air outlet of the air curtain device is connected by sliding The components are connected to the housing 2. The casing 2 encloses a cavity structure that can accommodate other components, and at least a part of the air curtain device in this embodiment is located in the cavity enclosed by the casing. At least part of the air outlet of the air curtain device is limited and supported by the casing. The air curtain device includes an air curtain duct providing a working space for the air curtain fan, and the outlet of the air curtain duct is an air outlet. At least part of the periphery of the air outlet is slidably connected with the casing. That is, when the relative position of the air outlet of the air curtain device is adjusted, ...

Abstract

The invention discloses an air curtain range hood, which comprises an air curtain device, and the air curtain device is at least used to generate a shielding air curtain for shielding oil smoke; The relative distance between the air suction ports of the hood is adjustable. The relative position relationship between at least part of the air outlet of the air curtain device of the range hood air curtain device introduced in the present invention and the air suction port can be adjusted, thereby realizing the adjustment of the effective distance for shielding the air flow of the air curtain.

Description

technical field [0001] The invention belongs to the field of kitchen air purification equipment, and in particular relates to an air curtain range hood. Background technique [0002] In the air curtain range hood in the prior art, an air curtain is arranged between the user and the pot and the stove to isolate the user from the oil fume. However, after the oil fume is generated near the mouth of the pot, the temperature is higher, and the components of oil and water are in a gaseous state, which is lower than the air density in the surrounding environment, and its upward trend is also very obvious. There is no need for an air curtain to shield the oil fume within a distance. In addition, the vertically downward air curtain air flow at this position drives the air at the mouth of the pot to flow downward, causing the air pressure at the mouth of the pot to decrease, which affects the upward diffusion of oil fumes. The kitchen environment is limited, and the space at the sto...
