Description
Technical Field

Background
In the air curtain range hood in the prior art, an air curtain is arranged between a user and a pot and between the user and a cooking bench to isolate the user from oil smoke. However, the temperature of the oil fume is higher after the oil fume is generated at a position close to the pot opening, the components of the oil and the water are in a gaseous state, the density of the oil fume and the water is lower than that of air in the surrounding environment, the rising trend of the oil fume and the water is very obvious, and the oil fume is shielded without an air curtain within a certain distance close to the pot opening. In addition, the air curtain airflow at the position downward relative to the vertical direction drives the air at the pot opening position to flow downward, so that the air pressure at the pot opening position is reduced, and the upward diffusion of the oil smoke is influenced. The kitchen environment is limited, the space of the cooking bench is more limited, and the air flowing phenomenon around the kitchen environment caused by the air curtain can influence the gas environment in the working area (above the cooking bench) of the range hood to different degrees. Therefore, the working effect of the range hood can be influenced by the overlarge action range of the air curtain airflow in the vertical direction. Furthermore, in the cooking process, the hands and arms of the user mostly act near the cooking bench or near the pot opening, and the large part of the air curtain flow inevitably blows on the hands and arms of the user, so that the user is uncomfortable. Particularly, some users are sensitive to airflow, and the skin temperature environment and the airflow environment in the vicinity of the same area cause allergic reactions. Therefore, how to reasonably control the effective distance of the air curtain airflow and avoid the problem that the invalid air curtain influences the oil smoke to rise or causes discomfort of a user becomes urgent to be solved.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and the following embodiments are used for illustrating the present invention and are not intended to limit the scope of the present invention.
In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1 to 5, the air curtain range hood introduced in the present invention includes an air curtain device 1' for generating a shielding air curtain for shielding oil smoke. The shielding air curtain comprises at least two air curtains (such as a first air curtain 1110 'and a second air curtain 1120') with different movement rates on the same height, the position of the initial end of at least one air curtain (or an air outlet corresponding to the air curtain) is adjustable, and then the effective distance of the airflow of the shielding air curtain is adjusted by controlling the position of the initial end of at least one air curtain. The air supply distance (effective distance of air curtain airflow) of the shielding air curtain is only in the range where the oil smoke begins to diffuse, and the shielding air curtain airflow is blocked (scattered) at the position where the oil smoke cannot diffuse, so that the influence of the air curtain airflow on flames near a pot opening, on a cooking bench and on the body of a user is avoided. The air curtain range hood introduced in the invention shields the oil smoke only at the position where the oil smoke has the diffusion phenomenon through the shielding air curtain. Thereby avoiding the pressure difference between the working area of the range hood (below the range hood, above the cooking bench and in the suction range of the range hood) and the surrounding environment (the position of the user) caused by the shielding air curtain function, and avoiding the negative influence caused by the range hood sucking the oil smoke.
Example one
In the air curtain range hood in this embodiment, the flow directions of the at least two air curtains at the starting ends of the air curtain airflow are parallel or form a certain included angle, and the included angle is smaller than 15 °. The technical solution in this embodiment requires that the two air curtains maintain directional consistency at least at their starting positions. Preferably, the air flow directions of the first air curtain and the second air curtain are at least at the beginning ends of the first air curtain and the second air curtain and are symmetrically arranged with the vertical direction.
The flow direction of the air curtain airflow at the initial end can be adjusted by the deflection angle of the air deflector at the air outlet of the air curtain range hood. When the equipment is in a stable use state, the air flows of at least two air curtains are kept in a parallel state as much as possible. Because the flow velocities of the two air curtains at the same height position are different, namely: at a certain height position, the airflow rate of one air curtain is always greater than that of the other air curtain, and the airflow directions of the two air curtains are kept in a certain row. The curtain having the greater velocity of the curtain airflow provides support for the curtain airflow having the lesser velocity of the curtain airflow, at least over a range of flow directions and velocities. The air curtain airflow with the small flow rate cannot be diffused too early, and the phenomenon that the flow speed of the airflow is obviously attenuated too early due to the increase of the flow distance is avoided. That is, the relatively high flow rate of the curtain air flow ensures that the direction and speed of the relatively low flow rate of the curtain air flow does not attenuate excessively over a substantial distance, at least adjacent the outlet opening of the curtain device. The distance range at least comprises the upper part of the working area of the range hood (the working area is the upper space of the cooking bench), the area is easy to generate oil smoke diffusion and is a part with serious oil smoke diffusion, and the shielding air curtain in the embodiment keeps the initial state of the air curtain generation to a greater extent in the air curtain direction and the air curtain flow direction in the area, so that the oil smoke can be well shielded in the area. Moreover, after the two air curtains with different flow rates flow for a certain distance, the phenomenon that the two air flows are converged is inevitable. When the two air flows are converged, the two air flows are scattered by each other due to the obvious change of the air flow direction. The directionality, the mobility and the flow speed of the scattered airflow are obviously changed, the airflow can not generate an obvious shielding effect on oil smoke, at the moment, the mixed airflow flows to the lower part of the working area, the position is close to a pot opening and stove flame, and due to the change of various properties of the airflow, the mixed airflow can not generate negative influence on the oil smoke below the working area and in a relatively concentrated flow direction, and can not influence the flame. Further, the air flow is supplemented to the lower part of the working area, and low pressure caused by the suction effect of the range hood is relieved.
Furthermore, the included angle between the shielding air curtain and the vertical direction in the embodiment is adjustable, and the included angle is adjusted by adjusting the deflection angle of the air deflector at the air outlet of the air curtain device. The flow direction of the beginning of the two air curtain flows can be characterized by the included angle between the central axis of the air curtain flow and the vertical direction.
Example two
The difference between the air curtain range hood described in this embodiment and the above embodiments is: the effective distance of the shielding air curtain airflow refers to: the shield air curtain airflow has a distance to flow when the shield air curtain airflow intensity/airflow velocity/airflow volume decays to 30% to 70% of the corresponding amount at the beginning of the shield air curtain airflow. The flowing distance of the shielding air curtain airflow is the distance along the vertical direction, or the projection of the actual motion track on the vertical direction. The size of the effective distance for shielding the air curtain airflow is determined by the using environment of the air curtain range hood, and when the phenomenon of oil smoke diffusion easily occurs in the using environment, the shielding effect of the air curtain is enhanced, and the effective distance for shielding the air curtain airflow is prolonged.
Further, the location of the beginning of the air curtain in this embodiment includes the relative heights of the beginning of the at least two air curtain flows. The solution in this embodiment can adjust the effective distance of the shielding air curtain by adjusting the relative heights of the beginning ends of the at least two air curtain flows. For example, when the distance between the starting end of the air curtain with higher flow speed and the starting end of the air curtain with lower flow speed in the two air curtains in the vertical direction is larger, the air curtain with higher flow speed performs the functions of flow direction keeping and flow rate acceleration after the flow performance of the air curtain with lower flow rate is attenuated to a certain degree, so that the effective distance of the shielding air curtain can be prolonged, and the positions where the two air curtains intersect are pushed downwards along the flow direction of the air curtain airflow, thereby avoiding the premature intersection of the two air curtains and avoiding the premature scattering of the air curtain airflow. Alternatively, the effective distance of the shield air curtain airflow can be shortened by reducing the relative height difference of the starting ends of the two air curtains in the air curtain airflow direction.
EXAMPLE III
As shown in fig. 3, the difference between the air curtain range hood of the present embodiment and the above embodiments is: the position of the starting ends of the air curtains comprises the relative height of the starting ends of the air flows of the at least two air curtains and/or the relative distance between the air outlets of the air curtains. Because two air curtains with different flow rates at the same relative height have a certain spacing distance between the positions of the respective air outlets (corresponding to the initial ends of the respective air curtain air flows). As the two air streams flow, and the air streams diverge to some extent in the direction of flow, the two air curtain streams meet. The two air curtain air flows start to obviously diverge from the intersection position (the end point of the effective distance of the shielding air curtain air flow), and when the distance between the two air curtains is smaller, the distance between the intersection position and the air outlet is relatively shorter; when the distance between the two air curtains is larger, the distance between the position where the two air curtains meet and the air outlet is relatively far. Then, the air supply distance of the shielding air curtain can be adjusted by controlling the starting ends (the distance between the two air outlets) of the two air curtains.
Further, in the range hood in this embodiment, because the two air curtains have different flow rates, the flow performance of the air curtain with the larger flow rate has better retention capability than the flow performance of the air curtain with the smaller flow rate, so that the phenomenon of air flow divergence after the two air curtains are intersected is mainly performed toward one side of the air curtain with the smaller flow rate. Preferably, when the range hood is designed, the air curtain airflow with low flow speed is arranged close to the working area. The diffused air flow is weaker, the upward movement of the oil smoke cannot be influenced, and the low-pressure phenomenon caused by the absorption of the oil smoke can be compensated.
Example four
As shown in fig. 1 to 5, the difference between the air curtain range hood of the present embodiment and the above embodiments is: the air curtain device comprises a first air outlet 111 'for generating a first air curtain 1110' and a second air outlet 112 'for generating a second air curtain 1120', the second air outlet 112 'is arranged at one side of the first air outlet 111' close to a user, and the air flow movement rates of the first air curtain 1110 'and the second air curtain 1120' are different on the same height. The shielding curtain includes the first curtain 1110 'and the second curtain 1120'. The air curtain device 1' in the embodiment is provided with the two air outlets, so that an additional air curtain device or an air curtain fan is not needed to be added, and the occupied equipment space is avoided. Preferably, the height of the first wind outlet 111 'in the shielding wind curtain airflow direction is greater than that of the second wind outlet 112', and the airflow speed of the second wind curtain 1120 'is greater than that of the first wind curtain 1110' at the same height. Because the air curtain airflow inevitably generates the phenomenon of flow performance attenuation along the flow direction, the larger the distance between the air curtain airflow and the air outlet (the initial end of the air curtain airflow) of the corresponding air curtain device is, the more serious the attenuation is, and the flow rate is relatively smaller. The technical scheme in this implementation sets up the relative height of two air outlets into having certain distance along the flow direction of shielding air current for the relative height at the top of two air curtains is different, and then the velocity of flow of the air curtain air current of two air curtains in same high position department is different.
EXAMPLE five
As shown in fig. 1 to 5, the difference between the air curtain range hood of the present embodiment and the above embodiments is: the air curtain range hood comprises a shell 2 ' forming the outer contour of the air curtain range hood, and an air outlet of the air curtain device is connected with the shell 2 ' through a sliding connection assembly, so that the air outlet can slide along the shell 2 '. The air outlet includes the first air outlet 111 'and/or the second air outlet 112'. The housing 2 ' encloses a cavity structure for accommodating other components, and at least a part of the air curtain device 1 ' in this embodiment is located in the cavity enclosed by the housing 2 '. At least part of the air outlet of the air curtain device is limited and supported by the shell. The air curtain device comprises an air curtain air duct which provides a working space for the air curtain fan, and an outlet of the air curtain air duct is an air outlet. At least part of the periphery of the air outlet is connected with the shell in a sliding mode. That is, when the relative position of the air outlet of the air curtain device is adjusted, the relative position of the air curtain device and the air curtain duct formed by the air curtain device is not changed, and only the relative position of the air outlet is changed. The second air outlet 112 ' in fig. 2 slides to the end of the sliding range far from the air suction opening 3 ', and the first air outlet 111 ' is located in the middle of the sliding range.
Further, the air outlet of the air curtain device in this embodiment includes the first air outlet 111 'and/or the second air outlet 112'. When the positions of the air outlets are adjusted, only the position of the first air outlet may be adjusted, only the position of the second air outlet may be adjusted, and both the positions of the second air outlet may be adjusted. When the position to second air outlet and first air outlet all adjusted, not only can adjust the effective air supply distance of shielding air curtain, can also adjust the distance between shielding air curtain and the user. Because the physical constitutions of the users are different, the relative positions of the users, the cooking range and the pot opening are different when cooking operation is carried out, and therefore the distance between the shielding air curtain and the users is adjusted, and the personalized requirements of the users are favorably met.
EXAMPLE six
As shown in fig. 1 to 5, the difference between the air curtain range hood of the present embodiment and the above embodiments is: the range hood comprises an air suction opening 3 'for sucking oil smoke, and the sliding direction of the sliding connection assembly comprises the direction/the reverse direction (A' direction) of the air outlet pointing to the air suction opening. Preferably, the direction/reverse direction of the air outlet pointing to the air suction opening is the front/rear direction of the air curtain range hood when the air curtain range hood is in a use state.
That is, when the user is in the cooking operation state, the sliding component slides at least in the front direction (a' direction shown in the figure) and the rear direction relative to the user, so as to adjust the relative distance between the air outlet and the air suction opening. Or, the air outlet position adjustment direction/sliding direction in the technical scheme in this embodiment may be performed along other directions, or adjusted universally. This adjustment requires the sliding connection assembly to be located at a plurality of corresponding locations on the outlet and the housing. The user/control system can adjust not only the front-rear direction of the air outlet but also the left-right direction of the air outlet.
Further, the sliding connection assembly in this embodiment includes a sliding card 52 ' respectively disposed on the air outlet and a sliding slot 51 ' disposed at a corresponding position of the housing 2 ', so as to realize sliding connection therebetween. The connection mode has simple structure, can ensure the smoothness of the connection position to a greater degree, and lays a foundation for the universal adjustment of the adjustment direction and the adjustment distance. Further, the sliding mode of the sliding connection assembly in this embodiment is controlled by the control system of the air curtain range hood and/or controlled by a user. Preferably, the sliding manner includes: sliding distance and/or sliding direction and/or sliding timing and/or sliding rate. Further preferably, at least a portion of the slide/chute is disposed at least one location around the air outlet. The slide card 52 and the slide groove 51 are always in a state of being at least partially matched and connected, and even if the air outlet slides to a limit position, the slide card 52 cannot be separated from the slide groove 51, so that the air outlet is always connected with the shell.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
