Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a wind curtain device and a cooking equipment. BACKGROUND

[0002] With the continuous improvement of people's living standards, people pursue higher quality of life, and people also put forward higher requirements for kitchen living environment. One of the biggest environmental problems in the kitchen is the oil fume generated during cooking. If not properly handled, the oil fume will spread throughout the kitchen, and even affect the living environment.

[0003] The existing oil fume exhaust rate is not very high, and combined with the use of public chimneys in buildings, more than 50% of the oil fume in the kitchen will not be easily discharged. During cooking in the kitchen, a large amount of oil fume still remains in the kitchen and spreads with the movement of people and the circulation of air. The existing researchers have thought of many kinds of processing schemes to improve the oil fume exhaust rate, such as increasing the oil fume cage area and improving the fan speed to increase the air volume, but these undoubtedly increase the space burden of the user and cause high noise, high energy consumption and other problems. Therefore, some range hoods that use a wind curtain device to solve the problem of preventing oil fume from spreading have appeared today. The wind curtain device generates a wind curtain, which forms a barrier around the oil fume collecting chamber or at the front end of the oil fume collecting chamber, thereby preventing oil fume from escaping and improving the smoke absorption effect of the oil fume.

[0004] The wind curtain device in the prior art can easily affect the normal operation of the range hood, and the airflow of the air outlet of the wind curtain device can easily affect the collection of flue gas by the range hood. UTILITY MODEL CONTENTS

[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 problem in the prior art that the airflow of the air outlet of the wind curtain device can easily affect the collection of flue gas by the range hood.

[0006] In order to solve the above technical problems, the first technical scheme adopted by the present application is to provide a wind curtain device, which is applied to a stove. The wind 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 which are in communication with the air duct. In the installed state, the air outlet is located at the top end of the shell and is configured to be located on the side of the stove close to the wall. The fan assembly is arranged in the air duct, and the fan assembly is used to blow air to the air outlet through the air duct to form an upward airflow above the air outlet, so that the flue gas generated by the stove is inclined in the direction 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, the air duct comprises the receiving cavity, the fan assembly is arranged in the receiving cavity, and the air inlet is arranged on the first shell. The second shell is arranged at the top end of the first shell, and the air outlet is arranged on the second shell.

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

[0009] Further, the side of the air outlet away from the wall surface is provided with a guide vane, and the guide vane is used to control the direction of the air flow blown out of the air outlet. Alternatively, the air outlet is provided with a guide vane, and the guide vane is used to control the direction of the air flow blown out of the air outlet.

[0010] Further, the guide vane is movably connected with the second shell, and the guide vane has a first state and a second state. In the first state, the guide vane covers the air outlet. In the second state, the opening angle of the guide vane is greater than or equal to 30° and less than or equal to 90°, so as to open the air outlet. The opening angle of the guide vane is the included angle between the guide vane and the plane on which the air outlet is located.

[0011] Further, the opening angle of the guide vane is positively correlated with the firepower level of the stove.

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

[0013] Further, in the installed state of the air curtain device, the air curtain device is symmetrically arranged relative to the center line of the stove.

[0014] To solve the above technical problems, a 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-mentioned embodiments. 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 outlet is in communication with the space in which the stove is arranged.

[0016] Beneficial effects: Different from the prior art, the wind curtain device provided by the application is applied to a cooking appliance, and 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 in communication with the air duct. In the installed state, the air outlet is located at the top end of the shell and is arranged on the side of the cooking appliance close to the wall surface. The fan assembly is arranged in the air duct and is used to blow air to the air outlet through the air duct to form upward air flow above the air outlet, so that the flue gas generated by the cooking appliance is inclined in the direction close to the wall surface. The wind curtain device provided by the application can be arranged alone beside the cooking appliance, thereby reducing the influence of the wind curtain device on the flue gas collection of the range hood. The wind curtain device forms upward air flow above the air outlet, and the upward air flow is arranged close to the wall surface. In this way, the air flow flows upward along the wall body at high speed to form a low-pressure area, and the flue gas rising in the pot flows to the rear end due to the pressure difference, thereby avoiding the flue gas from running on the front side and reducing the amount of flue gas inhaled by the human body on the front side. Moreover, because of the existence of the high-speed air flow on the wall side, although the oil fume moves backward, it does not directly contact the wall, thereby achieving the protection of the wall.

[0028] 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.

[0029] 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 an upward airflow through the air outlet to accelerate the rise of smoke from the rear of the cookware, forming a low negative pressure zone. This draws the smoke from the front towards the rear, reducing the amount of smoke at the front and the time the smoke stays in the room, preventing smoke from escaping from the front and harming the human body. Furthermore, it can form an airflow wall at the rear, preventing wall contamination. The air curtain device provided in this application will be described in detail below.

[0030] 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.

[0031] The shell 11 has an air duct (not shown in the figure), such as Figure 1 As shown, the housing 11 has an air inlet 101 and an air outlet 102 communicating with the air duct. When the air curtain device 10 is installed, the air outlet 102 is located at the top of the housing 11. See also... Figure 2 As shown, when the air curtain device 10 is installed, the air outlet 102 is configured to be located on the side of the stove 22 near the wall 40.

[0032] The fan assembly 12 is located inside the air duct. The fan assembly 12 is used to blow air through the air duct to the air outlet 102 to form an upward airflow above the air outlet 102, that is, to form an upward airflow behind the stove 22. In this way, a negative pressure zone can be formed behind the stove 22, so that the smoke generated by the stove 22 is tilted towards the wall 40.

[0033] In the above embodiments, such as Figure 2As shown, the air curtain device 10 can be arranged in a cabinet of a cooking bench, and the air curtain device 10 is arranged between the cooking bench 22 and the wall surface 40. The air outlet 102 of the air curtain device 10 is located at a side of the cooking bench 22 close to the wall surface 40. Under the action of the fan assembly 12, air blowing is performed at the air outlet 102, and an upward air flow is formed above the air outlet 102, which is arranged close to the wall surface 40. In this way, the air flow flows upward along the wall surface 40 at a high speed, forming a low-pressure area, and the smoke rising in the pot flows to the rear end due to the pressure difference, thereby avoiding smoke running in the front side and reducing the inhalation amount of smoke by a human body in the front side. Moreover, because of the existence of the high-speed air flow on the side of the wall surface 40, although the oil fume moves to the rear, it does not directly contact the wall surface 40, thereby protecting the wall surface 40.

[0034] Optionally, the fan assembly 12 can be a cross-flow fan assembly to ensure uniform air outlet at the air outlet 102. Optionally, the fan assembly 12 can also be a centrifugal fan or the like.

[0035] Further, as shown, Figure 1 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), which is part of an 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. 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 closely attached to the inner wall surface of the cabinet. It can be understood that the shape of the first shell 111 can also be a cylindrical shape 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 width of the second shell 112 is smaller than that of the first shell 111. The second shell 112 is provided with the air outlet 102, which is arranged above the first shell 111, so as to better guide the air in the air duct to the upper side of the air curtain device 10. 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 bench surface, so as to send air upward through the air outlet 102 of the second shell 112.

[0037] In the installed state of the air curtain device 10, the second shell 112 is arranged at the end of the first shell 111 close to the wall surface 40, the air inlet 101 is arranged at the side of the first shell 111 away from the wall surface 40, and the air inlet 101 is arranged opposite to the air outlet 102. The air inlet 101 is arranged at the bottom end of the first shell 111, and the air outlet 102 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 large, thereby reducing the interference between them.

[0038] In order to make the air outlet more uniform, a grid structure is arranged at the air outlet 102 to guide the direction of the airflow.

[0039] Further, as shown in the drawings, the air outlet 102 is provided with a deflector 13 away from the wall surface 40, and the deflector 13 is used to control the direction of the airflow blown out of the air outlet 102. Figure 1

[0040] In some embodiments, the deflector 13 can be fixedly connected with the second shell 112.

[0041] In other embodiments, the deflector 13 can also be movably connected with the second shell 112, that is, the deflector 13 is rotatably arranged at the end of the second shell 112 away from the wall surface 40. Specifically, the deflector 13 has a first state and a second state.

[0042] In the first state, the deflector 13 is arranged on the air outlet 102 to block the air outlet 102, so as to protect the air curtain device 10. When the air curtain device 10 is not used, the deflector 13 can be closed to facilitate cleaning the cooking surface, and to prevent dust from falling into the air duct of the air curtain device 10.

[0043] In the second state, the opening angle of the deflector 13 is greater than or equal to 30° and less than or equal to 90° to open the air outlet 102, wherein the opening angle of the deflector 13 is the angle between the deflector 13 and the plane where the air outlet 102 is located. When cooking, the deflector 13 of the air curtain device 10 can be opened to make the air curtain device 10 blow upward airflow from the air outlet 102.

[0044] After the air curtain device 10 blows air from the air outlet 102, the air is guided along the deflector 13 to a position close to the wall surface 40, and then flows upward along the wall surface 40 at high speed to form a low-pressure area. The smoke rising in the pot of the cooking appliance 22 will flow to the rear end due to the pressure difference, avoiding the front side from running smoke, reducing the amount of smoke inhaled by the human body on the front side, and because of the existence of high-speed airflow on the wall surface 40, the oil fume moves backward, but does not directly contact the wall surface 40, which protects the wall surface 40.

[0045] Further, the deflector 13 can also be provided with an adjusting portion (not shown in the drawings), which can be used to adjust the angle of the deflector 13. The airflow blown out of the air outlet 102 vertically upward along the wall surface 40 under the action of the deflector 13 to generate vertical upward airflow in the area close to the wall surface 40.

[0046] In other embodiments, as shown in the drawings, Figure 3 ​As shown, the guide vane 13 can be omitted, and instead, a guide vane 100 can be built into the air outlet 102. The guide vane 100 is used to control the direction of the airflow blowing out of the air outlet 102. By setting the built-in guide vane 100, the volume of the air curtain device 10 can be reduced, and the space occupied by the air curtain device 10 on the table can be reduced.

[0047] When the stove 22 is turned on, it simultaneously activates the air curtain device 10. The opening angle of the guide vane 13 is directly proportional to the firepower level of the stove 22. When the firepower of the stove 22 is at a low setting, the amount of oil fumes produced is small, the guide vane 13 only needs to open at a small angle, the fan assembly 12 runs at a low speed, and the low negative pressure zone on the wall 40 side is relatively thin. When the stove 22 is at a high firepower setting, the amount of oil fumes produced is large, the guide vane 13 opens at a large angle, the fan assembly 12 runs at a high speed, and the low negative pressure zone on the wall 40 side is relatively thick.

[0048] like Figure 4 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 zones 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 outlet 102 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 the air outlet 102 being too long. 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 causing smoke to be blown away due to excessively close proximity to the wall 40.

[0049] 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 an upward airflow behind the cooktop 22, creating a low negative pressure zone that accelerates the airflow backward, reducing smoke escape from the front and minimizing harm to the human body. Furthermore, the air curtain device 10 forms a wind wall on the wall 40, protecting it from oil fume pollution.

[0050] 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 includes: a stove 22, a range hood 21, and an air curtain device 10. The stove 22 is mounted on the stovetop; the range hood 21 is mounted above the stovetop; and the air curtain device 10 is located on the side of the stove 22 near the wall 40.

[0051] The air curtain device 10 is arranged on the side of the cooking bench away from the cookers 22, that is, the air curtain device 10 is arranged below the cooking bench, and the air outlet 102 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 occupy the space of the cooking bench, and is far away from the range hood 21, thereby reducing the influence on the smoke suction performance of the range hood 21.

[0052] In the cooking equipment 20 of the present application, the air flow generated by the air curtain device 10 flows upward along the wall surface 40 at a high speed, forming a low negative pressure area, and the smoke rising from the pot 30 flows to the rear end due to the pressure difference, thereby avoiding the smoke from running on the front side, reducing the amount of smoke inhaled by the human body on the front side, and because of the existence of the high-speed airflow on the side of the wall surface 40, the oil fume moves backward but does not directly contact the wall surface 40, thereby playing a protection role of the wall surface 40.

[0053] The above-mentioned 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-mentioned embodiments shall be included in the protection scope of the technical solutions.
