[0002] Consumers have higher and higher requirements for the performance of kitchen air purification equipment, and large suction has become the target pursued by major merchants, but the problems such as incomplete suction and oil smoke overflow cannot be solved by the oil smoke exhausters currently sold on the market. During the cooking process, a small part of oil smoke always escapes from the front part of the machine and directly invades the clothes, hair and face of the cook, which not only harms the face skin, but also induces respiratory diseases if inhaled by the human body for a long time, directly affecting the health of the user.

[0003] Therefore, in order to solve the problem of oil smoke escape, the oil smoke exhauster in the prior art is usually provided with a wind curtain device to isolate the user from the escaped oil smoke during use.

[0004] However, the wind curtain device in the prior art has a large range of action, which affects the working effect of the oil smoke exhauster. Moreover, the hands and arms of the user are usually moving near the cooking bench or the pot opening, and a large part of the wind curtain flow will inevitably blow on the hands and arms of the user, causing discomfort to the user. CONTENT OF THE INVENTION

[0005] In view of the problems in the background art, the purpose of the present application is to provide a wind curtain device and a cooking equipment to solve the technical problems that the wind curtain device in the prior art has a large range of action, which affects the working effect of the oil smoke exhauster and causes discomfort to the user.

[0006] In order to solve the above technical problems, the first technical solution adopted by the present application is to provide a wind curtain device, which is applied to a cooking bench. Specifically, the wind curtain device comprises a shell and a fan assembly. The shell is formed with an air duct, and the shell is provided with an air inlet and an air outlet which are communicated with the air duct. In the installed state, the air inlet is located at the top end of the shell and is arranged on the side of the cooking bench close to the wall. The fan assembly is arranged in the air duct and is used to suck air from the air inlet through the air duct to form a downward air flow above the air inlet, so that the smoke generated by the cooking bench is inclined to the side close to the wall.

[0007] Further, the shell comprises a first shell and a second shell. The first shell is formed with a receiving cavity, and the air duct comprises the receiving cavity. The fan assembly is arranged in the receiving cavity, and the air outlet is arranged on the first shell. The second shell is arranged at the top end of the first shell, and the air inlet is arranged on the second shell.

[0008] Further, in the installed state, the second shell is arranged at the end of the first shell close to the wall, and the air outlet is arranged on the side of the first shell away from the wall and opposite to the air inlet.

[0009] Further, the length of the first shell is greater than or equal to the length of the second shell, and the width of the first shell is greater than the width of the second shell, wherein the length direction of the first shell and the second shell is parallel to the wall surface, and the width direction of the first shell and the second shell is perpendicular to the wall surface.

[0010] Further, the air volume of the fan assembly is positively correlated with the fire power level of the stove.

[0011] Further, in the installed state, the air curtain device is symmetrically arranged relative to the center line of the stove.

[0012] Further, in the installed state, the distance between the air curtain device and the wall surface is L, wherein L is in the range of 20mm≤L≤100mm.

[0013] Further, in the installed state, the length of the shell is greater than the distance between the inner sides of the two pots on the stove and is less than the distance between the outer sides of the two pots.

[0014] To solve the above technical problems, the second technical scheme adopted by the present application is to provide a cooking equipment, which comprises a stove and the air curtain device of any one of the above embodiments, wherein the stove is arranged on a cooking bench; and the air curtain device is arranged on the side of the stove close to the wall surface.

[0015] Further, the air curtain device is arranged on the side of the cooking bench away from the stove, and the air inlet is in communication with the space where the stove is located.

[0016] Beneficial effects: Different from the prior art, the air curtain device provided by the present application is applied to the stove, and the air curtain device comprises a shell and a fan assembly. The shell forms an air duct, and the shell is provided with an air inlet and an air outlet in communication with the air duct. In the installed state, the air inlet is located at the top end of the shell and is arranged on the side of the stove close to the wall surface. The fan assembly is arranged in the air duct, and the fan assembly is used to suck air from the air inlet through the air duct to form a downward air flow above the air inlet, so that the smoke generated by the stove is inclined to the side close to the wall surface. The air curtain device of the present application is arranged on the cooking bench and is far away from the range hood, so the influence on the range hood is small. The air curtain device forms a downward air flow at the position close to the wall surface, and the air flow on the front side is supplemented. When the smoke is generated, the smoke will flow backward under the action of the downward rearward suction force of the air curtain device, and the upward component velocity of the smoke will also increase slowly, so that the smoke flows to the rear side and the middle side of the air curtain device, thereby reducing the smoke running on the front side and reducing the influence of the oil smoke on the human body on the front side. Moreover, due to the existence of the high-speed air flow on the wall side, although the oil smoke moves backward, it will not directly contact the wall surface, thereby achieving the protection effect of the wall surface.

[0027] A range hood is a kitchen appliance used to purify the kitchen environment. It's typically installed above the stovetop, with a certain distance between them, usually around 750mm. However, because range hoods passively extract cooking fumes, they are susceptible to crosswinds as the fumes rise, causing them to easily escape. Adding an air curtain device to the range hood helps prevent these fumes from easily escaping into the kitchen space, ensuring they are effectively drawn away by the hood.

[0028] This application first provides an air curtain device, which is installed on the rear side of the stove (the side closest to the wall). The air curtain device generates a downward airflow through its air inlet, drawing the smoke from the front towards the rear, reducing the amount of smoke at the front, and reducing the time the smoke stays in the room, preventing smoke from escaping from the front and harming people. It can also form an airflow wall at the rear, preventing wall pollution. The air curtain device provided in this application will be described in detail below.

[0029] Please see Figure 1 As shown, Figure 1 This is a schematic diagram of an embodiment of an air curtain device provided in this application. Specifically, the air curtain device 10 includes: a housing 11 and a fan assembly 12 located inside the housing 11.

[0030] The shell 11 has an air duct (not shown in the figure), such as Figure 1As shown, 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 air curtain device 10, the air inlet 101 is located at the top end of the shell 11. Referring again to Figure 2 As shown, in the installed state of the air curtain device 10, the air inlet 101 is arranged to be located at the side of the stove 22 close to the wall surface 40.

[0031] As shown, Figure 1 The fan assembly 12 is arranged in the air duct, and is used to suck air from the air inlet 101 through the air duct, drive the air flow at the side of the wall surface 40 to flow downward, and give the air flow an initial downward velocity, and the front side air flow is supplemented. When the flue gas is generated, the flue gas will flow backward under the suction force given by the air curtain device 10, and the upward component velocity of the flue gas will also increase slowly, so that the flue gas flows to the middle side of the air curtain device 10 from the rear side. The downward air flow is formed at the rear side of the stove 22, so that a negative pressure area is formed at the rear side of the stove 22, and the flue gas generated by the stove 22 is inclined towards the wall surface 40 (as shown). Figure 2

[0032] In the above embodiment, as shown, Figure 2 The air curtain device 10 is arranged in the cabinet of the cooking bench, and is arranged between the stove 22 and the wall surface 40. The air inlet 101 of the air curtain device 10 is located at the side of the stove 22 close to the wall surface 40. Under the action of the fan assembly 12, air is sucked at the air inlet 101, and downward air flow is formed above the air inlet 101, and the downward air flow is arranged close to the wall surface 40. In this way, the flue gas flows backward, and the upward component velocity of the flue gas also increases slowly, so that the flue gas flows to the middle side of the air curtain device 10 from the rear side, reduces the flue gas running in the front side, reduces the inhalation amount of the flue gas by the human body in the front side, and because of the existence of the air flow at the side of the wall surface 40, the flue gas moves backward, but does not directly contact the wall surface 40, thereby protecting the wall surface 40.

[0033] Optionally, the fan assembly 12 can be a cross-flow fan assembly to ensure that the air outlet 102 uniformly discharges air. Optionally, the fan assembly 12 can also be a centrifugal fan or the like.

[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 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, Figure 1 ​As shown, the shell 11 can include a first shell 111 and a second shell 112, the first shell 111 is formed with a receiving cavity (not labeled in the figure), the receiving cavity 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 outlet 102 is arranged on the first shell 111. The shape of the first shell 111 can be a cuboid, so that when the shell 11 is placed in the cabinet, it can be close to the inner wall of the cabinet. It can be understood that the shape of the first shell 111 can also be cylindrical or the like, which can be selected and arranged as needed.

[0036] The second shell 112 is arranged at the top end of the first shell 111, and the second shell 112 is provided with an air inlet 101, which is arranged above the first shell 111 to suck air from the space where the stove 22 is located. When the air curtain device 10 is installed, the first shell 111 can be located in the cabinet, and the second shell 112 is embedded in the opening of the cooking table surface, so that the air inlet 101 on the second shell 112 is in communication with the space where the stove 22 is located.

[0037] Further, the length of the first shell 111 is greater than or equal to the length of the second shell 112, and the width of the first shell 111 is greater than the width of the second shell 112, wherein the length direction of the first shell 111 and the second shell 112 is parallel to the wall surface, and the width direction of the first shell 111 and the second shell 112 is perpendicular to the wall surface. This arrangement makes the second shell 112 match the opening of the cooking table surface, facilitating the installation of the air curtain device 10.

[0038] In the installed state of the air curtain device 10, the second shell 112 is arranged at one end of the first shell 111 close to the wall surface 40, the air outlet 102 is arranged on the side of the first shell 111 away from the wall surface 40, and is arranged opposite to the air inlet 101. The air outlet 102 is arranged at the bottom end of the first shell 111, and the air inlet 101 is arranged above the second shell 112. In the installed state of the air curtain device 10, the air outlet 102 faces upward, and the air inlet 101 faces downward. In this way, the distance between the air outlet 102 and the air inlet 101 can be larger, reducing the interference between them.

[0039] In Figure 1 In the embodiment shown, a grid structure is arranged at the air inlet 101 to make the air inlet 101 more uniform. In other embodiments, the air inlet 101 can also not be provided with the above-mentioned grid structure, so that the structure of the air curtain device 10 can be simplified, and the weight of the air curtain device 10 can be reduced.

[0040] The air curtain device 10 draws air from the air inlet 101 to form a downward airflow above the air inlet 101, thereby creating a low negative pressure zone. The smoke rising from the pot on the stove 22 will flow to the rear due to the pressure difference, preventing smoke from escaping from the front section and reducing the amount of smoke inhaled by people at the front. Furthermore, because there is a high-speed airflow on the wall 40 side, although the fumes move backward, they will not directly contact the wall 40, thus protecting the wall 40.

[0041] When the stove 22 is turned on, the airflow of the fan assembly 12 is directly proportional to the firepower level of the stove 22. When the stove 22 is turned on, it also activates the air curtain device 10. The airflow of the air curtain device 10 is related to the firepower level of the stove 22. When the firepower of the stove 22 is at a low setting, less smoke is produced, the fan assembly 12 runs at a low speed, and the airflow velocity on the wall side is low, resulting in a weak effect on dragging away the smoke. When the firepower of the stove 22 is at a high setting, more smoke is produced, the fan assembly 12 runs at a high speed, the airflow velocity is increased, and the dragging effect is enhanced.

[0042] like Figure 3 As shown, the air curtain device 10, in its installed state, is positioned between the cookware 30 and the wall 40. The air curtain device 10 can be symmetrically positioned relative to the centerline of the stove 22 to ensure more even force distribution across the cooking areas of the two stoves 22. Taking a 320mm 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, preferably L1≤L2≤L3. This arrangement allows the air curtain device 10 to cover the smoke-generating areas on both sides without causing smoke to escape from the sides due to an excessively long air inlet 101. In its installed state, the distance between the air curtain device 10 and the wall 40 is L, where L ranges from 20mm≤L≤100mm. This method protects the wall 40 without reducing the dragging effect of the air curtain device 10 on the oil fumes.

[0043] In summary, the air curtain device 10 provided in this application has a simple structure. It can be installed entirely within a cabinet without occupying space on the countertop or in the range hood 21. The air curtain device 10 generates a downward airflow behind the stove 22, driving the airflow to the rear and reducing smoke escape from the front, thus minimizing harm to the human body. Furthermore, the air curtain device 10 forms an air wall on the side of the wall 40, protecting the wall 40 from oil fume pollution.

[0044] This application also provides a cooking device; please refer to [link / reference]. Figure 2 As shown, Figure 2 This is a schematic diagram of an embodiment of a cooking device provided in this application. Specifically, the cooking device 20 may include: a stove 22, a range hood 21, and an air curtain device 10.

[0045] The cookers 22 are arranged on the cooking table, the range hood 21 is arranged above the cooking table, and the air curtain device 10 is arranged on one side of the cookers 22 close to the wall surface 40.

[0046] Further, the air curtain device 10 can be arranged on the side of the cooking table away from the cookers 22, that is, the air curtain device 10 is arranged at the bottom of the cooking table, and the air inlet 101 of the air curtain device 10 is in communication with the space where the cookers 22 are arranged. In this way, the air curtain device 10 does not temporarily use the space of the cooking table surface, and is far away from the range hood 21, thus having less influence on the smoke suction performance of the range hood 21.

[0047] In the cooking equipment 20 of the present application, the air flow generated by the air curtain device 10 flows downward at high speed along the wall surface 40 to form a low negative pressure area, so that the entire flue gas flows backward, and the upward component velocity of the flue gas also increases slowly, thus forming a phenomenon that the entire flue gas flows to the rear side and the middle side of the air curtain device 10, avoiding the smoke from running on the front side, and reducing the amount of smoke inhaled by the human body on the front side. Moreover, because of the existence of the high-speed airflow on the wall surface 40 side, although the oil fume moves backward, it does not directly contact the wall surface 40, thus playing a protection role of the wall surface 40.

[0048] The above-described embodiments do not constitute a limitation on the protection scope of the technical solutions. Any modification, equivalent replacement and improvement made within the spirit and principles of the above-described embodiments shall be included in the protection scope of the technical solutions.
