[0027] The range hood is a kind of kitchen appliance for purifying kitchen environment. The range hood is usually arranged above the cooking bench and needs to be spaced apart from the cooking bench by a certain distance, generally about 750mm. However, since the range hood is a passive device for sucking oil fume, the oil fume is prone to escape due to the influence of crosswind during the rising of the oil fume. When the range hood is in use, the wind curtain device is added, and the wind curtain device mainly forms an air curtain so that the oil fume generated during cooking cannot easily escape into the kitchen space, so that the oil fume can be sucked away by the range hood.

[0028] The present application first provides a wind curtain device arranged at the rear side (the side close to the wall surface) of the cooking bench. The wind curtain device generates downward airflow through the air inlet thereon, drives the front side flue gas to the rear side, reduces the amount of front side flue gas, and reduces the residence time of flue gas in the house, avoids the front side flue gas escaping and harming the human body, and can form an airflow wall at the rear side to avoid wall pollution. The wind curtain device provided by the present application will be described in detail below.

[0029] Please refer to Figure 1 and Figure 2 , Figure 1 is a structural schematic view of an embodiment of the wind curtain device provided by the present application, Figure 2 is a structural schematic view of an embodiment of the cooking equipment provided by the present application, and the cooking equipment 20 comprises the wind curtain device 10. Specifically, the wind curtain device 10 comprises a shell 11 and a fan assembly 12 located in the shell 11.

[0030] Among them, the shell 11 is formed with an air duct (not marked in the figure), as Figure 1 indicated, the shell 11 is provided with an air inlet 101 and an air outlet 102 which are in communication with the air duct. In the installed state of the wind curtain device 10, the air inlet 101 and the air outlet 102 are both located at the top end of the shell 11.

[0031] Please refer to Figure 2 indicated, in the installed state of the wind curtain device 10, the air inlet 101 is arranged at the side of the cooking bench 22 close to the wall surface 40. The air outlet 102 is arranged at the side of the cooking bench 22 away from the wall surface 40.

[0032] As Figure 2 indicated, the fan assembly 12 is arranged in the air duct. The fan assembly 12 is used to suck air from the air inlet 101 through the air duct and blow air at the air outlet 102, so as to form downward airflow above the air inlet 101 and form airflow inclined upward to the side of the wall surface 40 above the air outlet 102, so that the flue gas generated by the cooking bench 22 is inclined to the side close to the wall surface 40.

[0033] Specifically, the air curtain device 10 draws air from the air inlet 101, drives the air flow on the wall surface 40 side to flow downward, and gives the air flow an initial downward velocity. When the smoke is generated, the rear side smoke will be subjected to the downward and inward suction force given by the air curtain device 10, and the front side air flow will be supplemented to drag the smoke. The air flow drawn in from the air inlet 101 is discharged from the air outlet 102 through the air curtain device 10, which gives the front side smoke an accelerating effect of flowing inward and upward, and exerts a traction effect on the smoke. Under the superposition of the two effects, the smoke will have a tendency to flow toward the wall surface 40 side. The reduction of the front side and side edge smoke can reduce the working air volume of the range hood 21 when the range hood 21 is working, and achieve a better smoke suction effect. At the same time, the front side smoke flow is accelerated, and a certain effect of the air curtain wall is formed to avoid the front side smoke from harming the human body. Figure 2 Moreover, because of the existence of the air flow on the wall surface 40 side, the oil fume moves backward, but does not directly contact the wall surface 40, thereby protecting the wall surface 40.

[0034] Optionally, an oil fume adsorption device can be arranged at the air inlet 101 and / or the air outlet 102, and the oil fume adsorption device is used to adsorb the oil fume. In this way, the amount of oil fume entering the shell 11 can be reduced, and the fan assembly 12 in the shell 11 is prevented from being polluted.

[0035] Further, as shown in Figure 1 , the shell 11 can include a first shell 111, a second shell 112 and a third shell 113 connected in sequence and bent. The first shell 111 is formed with a receiving cavity (not marked in the figure), which is part of the air duct of the air curtain device 10. The fan assembly 12 is arranged in the receiving cavity, and the air inlet 101 is arranged on the first shell 111. As shown in Figure 1 , the first shell 111 can be arranged in a stepped manner. The air inlet 101 is arranged at the top of the first shell 111, and the fan assembly 12 is arranged in the space at the bottom of the first shell 111. In this way, when the shell 11 is placed in the cabinet, the top of the first shell 111 is embedded in the rear opening of the cooking bench, and the bottom of the first shell 111 is placed under the cooking bench.

[0036] The third shell 113 is arranged opposite to the first shell 111, and the first shell 111, the second shell 112 and the third shell 113 are arranged in a U-shaped manner as a whole. The third shell 113 is provided with the air outlet 102. When the air curtain device 10 is installed, the third shell 113 can be embedded in the front opening of the cooking bench, and the second shell 112 is arranged in the cooking bench.

[0037] In Figure 1In the illustrated embodiment, a grille structure is provided at the air inlet 101 to allow for more uniform air intake. In other embodiments, the grille structure may not be provided at the air inlet 101, thus simplifying the structure of the air curtain device 10 and reducing its weight.

[0038] The air curtain device 10 draws air in from the air inlet 101, creating a downward airflow above the inlet 101. The smoke rising from the pot on the stove 22 flows towards the rear due to the pressure difference and exits at the air outlet 102, accelerating the smoke from the front inwards and upwards, increasing the dragging and pulling effect. The combined effect of these two factors causes the smoke to tend to flow towards the wall 40.

[0039] Furthermore, such as Figure 1 As shown, a guide vane 13 is provided on the side of the air outlet 102 away from the wall 40. The guide vane 13 is used to control the direction of the airflow blown out of the air outlet 102.

[0040] In some embodiments, the guide vane 13 may be fixedly connected to the third housing 113.

[0041] In other embodiments, the guide vane 13 may also be movably connected to the third housing 113, that is, the guide vane 13 is rotatably disposed at the end of the third housing 113 away from the wall 40. Specifically, the guide vane 13 has a first state and a second state.

[0042] In the first state, the guide vane 13 covers the air outlet 102 to block the air outlet 102 and protect the air curtain device 10. When the air curtain device 10 is not in use, the guide vane 13 can be closed to facilitate cleaning of the stove surface and to prevent dust from falling into the air duct of the air curtain device 10.

[0043] In the second state, the guide vane 13 opens the air outlet 102. Preferably, the opening angle of the guide vane 13 can be greater than or equal to 30° and less than or equal to 90°, wherein the opening angle of the guide vane 13 is the angle between the guide vane 13 and the plane containing the air outlet 102. When cooking, the guide vane 13 of the air curtain device 10 can be opened to allow the air curtain device 10 to blow upward airflow from the air outlet 102.

[0044] Furthermore, the guide vane 13 may also be provided with an adjustment part (not shown in the figure), which can be used to adjust the angle of the guide vane 13.

[0045] In other embodiments, such as Figure 3As shown, the flow guide vane 13 can also not be arranged, and a guide vane (not shown in the figure) is arranged in the air outlet 102, and the guide vane is used to control the direction of the air flow blown at the air outlet 102. By arranging the guide vane, the volume of the air curtain device 10 can be reduced, and the occupation of the air curtain device 10 to the countertop space is reduced.

[0046] Further, when the cookers 22 are turned on, the air volume of the fan assembly 12 is positively correlated with the fire power of the cookers 22. When the cookers 22 are turned on, the air curtain device 10 is also turned on, and the air volume of the air curtain device 10 is related to the fire power of the cookers 22. When the fire power of the cookers 22 is at a low level, the amount of oil fume generated is small, the fan assembly 12 runs at a low speed, and the flow rates of the front side and the rear side are low. When the fire power of the cookers 22 is at a high level, the amount of oil fume generated is large, the fan assembly 12 runs at a high speed, and the flow rates of the two sides are increased, thereby increasing the dragging and pulling effects.

[0047] As shown in Figure 3 In the installed state, the air curtain device 10 is arranged between the pots 30 and the wall surface 40, and the air curtain device 10 can be symmetrically arranged relative to the center line of the cookers 22, so that the forces on the cooking areas corresponding to the two cookers 22 are more uniform. Taking a 320 mm diameter pot as an example, after the two pots are placed normally, the closest distance between the two pots 30 is L1, and the farthest distance is L3. The length of the air inlet 101 of the air curtain device 10 is L2, and preferably, L1≤L2≤L3. In this arrangement, the air curtain device 10 can cover the smoke generating areas on the left and right sides, and will not cause the smoke to run to the sides due to the air inlet 101 being too long. In the installed state, the distance between the air curtain device 10 and the wall surface 40 is L, and the range of L is: 20mm≤L≤100mm. In this way, the wall surface 40 can be protected, and the dragging effect of the air curtain device 10 on the oil fume is not reduced.

[0048] In summary, the air curtain device 10 provided by the present application has a simple structure, and the air curtain device 10 can be installed as a whole in the cabinet without occupying the space of the outer countertop and the range hood 21. The airflow sucked in by the air curtain device 10 from the air inlet 101 is discharged from the air outlet 102, which accelerates the front side smoke gas upward and applies a pulling effect on the smoke gas. Under the superposition of the two effects, the smoke gas will have a tendency to flow to the wall surface 40 side. Reducing the front side and side smoke running can reduce the working air volume of the range hood 21 when the range hood 21 is working, and a better smoke absorption effect can be achieved. Moreover, the air curtain device 10 accelerates the flow of the front side smoke gas while forming a certain effect of the air curtain wall, thereby avoiding the front side smoke gas from harming the human body.

[0049] The present application also provides a cooking equipment, please refer to Figure 2 As shown in Figure 2is a structural schematic view of an embodiment of a cooking device provided by the present application. Specifically, the cooking device 20 can include a cooktop 22, an extractor hood 21, and a wind curtain device 10.

[0050] The cooktop 22 is arranged on a cooktop, the extractor hood 21 is arranged above the cooktop, and the wind curtain device 10 is arranged apart from the cooktop. The structure of the wind curtain device 10 can refer to the introduction of any of the above embodiments, and will not be described here.

[0051] Further, the wind curtain device 10 can be arranged on a side of the cooktop away from the cooktop 22, that is, the wind curtain device 10 is arranged at the bottom of the cooktop, and the air inlet 101 and the air outlet 102 of the wind curtain device 10 are in communication with the space where the cooktop 22 is located. In this way, the wind curtain device 10 does not temporarily use the space of the cooktop surface, and is far away from the extractor hood 21, thus having less influence on the smoke suction performance of the extractor hood 21.

[0052] In the cooking device 20 of the present application, the airflow sucked in by the wind curtain device 10 from the air inlet 101 is discharged from the air outlet 102 of the wind curtain device 10, giving the front side flue gas an accelerating effect of flowing upward, and applying a traction effect on the flue gas. Under the superposition of the effects of the two, the flue gas will form a tendency to flow to the wall surface 40 side. Reducing the front side and side edge smoke running can reduce the working air volume of the extractor hood 21 when working, and achieve a better smoke suction effect. Moreover, the wind curtain device 10 accelerates the flow of the front side flue gas while forming a wind curtain wall with a certain effect, avoiding the front side flue gas from harming the human body.

[0053] The above-described embodiments do not constitute a limitation on the protection scope of the technical solutions. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the above-described embodiments are included in the protection scope of the technical solutions.
