Although it can meet the flame retardancy and heat resistance requirements of relevant national standards, under the condition of long-term operation, such as frequent stir-frying and the pot catching fire, the temperature at the bottom of the smoke collecting hood is too high, resulting in deformation and damage of the lamp housing. Summary of the Invention

[0003] In order to solve the problem that the lamp housing of the current range hood is prone to deformation, the present invention provides a range hood.

[0004] The present invention is implemented as follows:

[0005] The present invention provides a range hood, which includes a range hood body, a lighting assembly, and a glass flap assembly and a driving assembly both connected to the range hood body;

[0006] The lighting assembly is connected to the glass flap assembly and is used to shoot light into the glass flap assembly. The driving assembly is also connected to the glass flap assembly and is used to drive the glass flap assembly, and drive the lighting assembly to flip downward relative to the range hood body, so that the light in the glass flip assembly can be refracted from one side of the glass flap assembly facing the cooker and then shoot towards the cooker;

[0007] The driving assembly is also used to drive the glass flap assembly, and drive the lighting assembly to flip upward relative to the range hood body, so that the angle formed by the lighting assembly and the horizontal direction is at least 0°.

[0008] A further improvement of the range hood of the present invention is that when the lighting assembly flips downward in place, the light of the lighting assembly is refracted into the glass flap assembly from one side of the glass flap assembly facing away from the cooker, and then refracted out from one side of the glass flap assembly facing the cooker and then shoots towards the cooker.

[0009] A further improvement of the range hood of the present invention is that the lighting assembly includes a lamp housing and a lighting lamp arranged in the lamp housing; the lamp housing is clamped at the bottom of the glass flap assembly.

[0010] A further improvement of the range hood of the present invention is that the lamp housing is provided with a card slot and a lamp slot; the glass flap assembly is clamped in the card slot, and the lighting lamp is installed in the lamp slot.

[0011] A further improvement to the range hood of the present invention is that the lamp housing further comprises a clamping member and a mounting plate; the clamping member is provided with the clamping groove to form a U-shaped structure, the mounting plate is connected to a side wall of the clamping member, and the mounting plate is provided with the lamp groove.

[0012] A further improvement to the range hood of the present invention is that the lamp groove is an inclined groove inclined obliquely downward, and the angle between the two inclined surfaces of the lamp groove is 15° to 25°.

[0013] A further improvement to the range hood of the present invention is that the glass flap assembly comprises a glass plate and a connecting piece; the bottom of the glass plate is connected to the lighting assembly, the glass plate is connected to the range hood body via the connecting piece, and the driving assembly is connected to the connecting piece and / or the glass plate.

[0014] A further improvement to the range hood of the present invention is that the connecting member comprises a connecting plate and connecting protrusions; the connecting plate is connected to the glass plate, and the connecting plate is connected to the range hood body via the connecting protrusions.

[0015] A further improvement to the range hood of the present invention is that the driving assembly includes a driving member and a connecting rod; the driving member is connected to the glass flip assembly through the connecting rod to drive the glass flip assembly and drive the lighting assembly to flip upward or downward relative to the range hood body.

[0016] A further improvement to the range hood of the present invention is that the flip angle of the lighting assembly after it is reversed downward into position is 110° to 130°.

[0017] Compared with the prior art, the beneficial effects of the present invention using the above scheme are:

[0018] When lighting is needed, the driving assembly starts, drives the glass flap assembly, and drives the lighting assembly to flip downward relative to the range hood body, so that the light in the glass flip assembly can be refracted from the side of the glass flap assembly facing the cooker and then emitted to the cooker, and cooking lighting can be achieved at this time. At the same time, because the light emitted by the lighting assembly is finally refracted from the side of the glass flap assembly facing the cooker and then emitted to the cooker, when lighting is needed, the lighting assembly will definitely not be between the glass flap assembly and the cooker. In order to ensure that the light can be successfully refracted from the side of the glass flap assembly facing the cooker and then emitted to the cooker, the glass flap assembly is between the lighting assembly and the cooker, so as to avoid the lighting assembly from directly contacting the high-temperature oil smoke, and effectively solve the problem that the lighting lamp housing of the current range hood is prone to deformation.

Detailed implementation manners

[0031] In order to more clearly understand the above-mentioned objects, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0032] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0033] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", "rear", "left", "right", "axial direction", "radial direction", etc. is the orientation or positional relationship based on the installation state when this range hood is installed for users.

[0034] In the present invention, unless otherwise clearly defined and limited, terms such as "installation", "connection", "attachment", "fixation", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] As Figures 1-5 shown, this embodiment provides a range hood, including a range hood body 1, a lighting assembly 2, and a glass flap assembly 3 and a driving assembly 4 both connected to the range hood body 1;

[0036] The lighting assembly 2 is connected to the glass flap assembly 3 and is used to project light into the glass flap assembly 3. The driving assembly 4 is also connected to the glass flap assembly 3 and is used to drive the glass flap assembly 3 and drive the lighting assembly 2 to turn downward relative to the range hood body 1, so that the light in the glass flap assembly 3 can be refracted from one side of the glass flap assembly 3 facing the cooker and then projected onto the cooker;

[0037] The driving assembly 4 is also used to drive the glass flap assembly 3 and drive the lighting assembly 2 to turn upward relative to the range hood body 1, so that the angle formed by the lighting assembly 2 and the horizontal direction is at least 0°.

[0038] When lighting is required, the driving component 4 is activated, driving the glass flap component 3 and driving the lighting component 2 to flip downward relative to the range hood body 1, so that the light in the glass flap component 3 can be refracted from one side of the glass flap component 3 facing the cooking stove and then shot towards the cooking stove, and cooking lighting can be achieved at this time. At the same time, because the light emitted by the lighting component 2 is finally refracted from one side of the glass flap component 3 facing the cooking stove and then shot towards the cooking stove, when lighting is required, the lighting component 2 will surely not be between the glass flap component 3 and the cooking stove. In order to ensure that the light can be successfully refracted from one side of the glass flap component 3 facing the cooking stove and then shot towards the cooking stove, the glass flap component 3 is between the lighting component 2 and the cooking stove, thus avoiding the lighting component 2 from directly contacting the high-temperature oil fume and effectively solving the problem that the lamp housing of the current range hood is prone to deformation.

[0039] When the lighting is stopped, the driving component 4 will drive the glass flap component 3 again and drive the lighting component 2 to flip upward relative to the range hood body, so that the angle formed by the lighting component 2 and the horizontal direction is at least 0°, which is to prevent the user from seeing the lighting component 2 when facing the range hood body and ensure the overall aesthetics of the range hood.

[0040] In order to ensure that as much light as possible refracted from one side of the glass flap component 3 facing the cooking stove can be shot towards the cooking stove, in a specific embodiment, the flipping angle of the lighting component 2 after flipping downward in place is 110° - 130°, preferably 120°.

[0041] In a specific embodiment, the lighting component 2 is usually installed at the front end of the range hood body 1, so the glass flap component 3 passes through the smoke collecting hood 11 and is connected to the front end wall of the range hood body 1.

[0042] As Figures 1-5 shown, further, after the lighting component 2 flips downward in place, the light of the lighting component 2 is refracted into the glass flap component 3 from one side of the glass flap component 3 facing away from the cooking stove, and then refracted from one side of the glass flap component 3 facing the cooking stove and shot towards the cooking stove. Further, the lighting component 2 is far away from the cooking stove, avoiding the influence of high temperature on the lighting component 2, and at the same time realizing cooking lighting.

[0043] As Figures 6-8 shown, further, the lighting component 2 includes a lamp housing 21 and a lighting lamp 22 arranged in the lamp housing 21; the lamp housing 21 is clamped at the bottom of the glass flipping component 3.

[0044] The lamp housing 21 is provided with a clamping groove 211 and a lamp groove 212; the glass flap component 3 is clamped in the clamping groove 211, and the lighting lamp 22 is installed in the lamp groove 212.

[0045] In order to make the light refract into the glass flap assembly 3 from one side facing away from the cooktop, the lighting lamp 22 is installed between the glass flip assembly 3 and the lamp housing 21 and is adjacent to one side of the glass flap assembly 3 facing away from the cooktop. In order to prevent the light from being blocked by the other side wall of the lamp housing 21, the lamp groove 212 is provided above the card slot 211.

[0046] As Figure 7 and Figure 8 shown, the lamp housing 21 further includes a clamping member 213 and a mounting plate 214; a card slot 211 is provided on the clamping member 213 to form a U-shaped structure, the mounting plate 214 is connected to one side wall of the clamping member 213, and a lamp groove 212 is provided on the mounting plate 214.

[0047] When the glass flip assembly 3 is clamped in the card slot 211, the mounting plate 214 fits against one side of the glass flip assembly 3. Since when the lighting assembly 2 is flipped in place, the light refracts into the glass flap assembly 3 from one side facing away from the cooktop, the mounting plate 214 fits against one side of the glass flap assembly 3 facing away from the cooktop, preventing users from seeing the lighting lamp 22 from outside the smoke exhaust hood 11 and ensuring aesthetics. In addition, the lamp housing 21 is preferably made of an aluminum profile high-temperature resistant material, and its size is compatible with that of the glass flip assembly 3. The clamping member 213 and the glass flap assembly 3 are also connected by screws or the like to prevent the glass flap assembly 3 from falling out of the card slot 211.

[0048] The height at which users install the range hood is generally limited to 650 mm to 700 mm above the cooking stove. Therefore, in order to make the light refracted from one side of the glass flap assembly 3 facing the cooktop shine towards the cooktop as much as possible, in a specific implementation, the lamp groove 212 is an inclined groove inclined obliquely downward, and the included angle α between the two inclined surfaces of the lamp groove 212 is 15° to 25°, preferably 18°.

[0049] As Figures 9-11 shown, the glass flap assembly 3 includes a glass plate 31 and a connecting member 32; the bottom of the glass plate 31 is connected to the lighting assembly 2, the glass plate 31 is connected to the range hood body 1 through the connecting member 32, and the driving assembly 4 is connected to the connecting member 32 or / and the glass plate 31. In this embodiment, the driving assembly 4 is movably connected to the connecting member 32.

[0050] For example, in a specific embodiment, the bottom of the glass plate 31 is clamped in the card slot 211, and the mounting plate 214 is attached to one side surface of the glass plate 31 to prevent the light from emitting through the gap between the mounting plate 214 and the glass plate 31. In addition, in order to achieve the firm connection between the glass plate 31 and the lamp housing 21, the glass plate 31 and the lamp housing 21 are also connected by screws or the like. The upper part of the glass plate 31 is connected to the range hood body 1 through a connecting member 32, and the driving assembly 4 is connected to the connecting member 32. By driving the glass plate 31 and driving the lamp housing 21, the illuminating lamp 22 can be turned downward or upward relative to the range hood body 1. When it is turned downward to the in-place position, the light of the illuminating lamp 22 is refracted into the glass plate 31 from one side surface of the glass plate 31 facing away from the cooking stove, and then refracted out from the side surface of the glass plate 31 facing the cooking stove and then emitted to the cooking stove.

[0051] In a specific embodiment, the connecting member 32 passes through the smoke collecting hood 11 and is connected to the front side wall of the range hood body 1. In order to prevent the oil fume from entering the smoke collecting hood 11 through the opening of the smoke collecting hood and polluting the electrical components, sealing rubber plugs are provided at the openings of the smoke collecting hood 11.

[0052] Preferably, one side surface of the glass plate 31 facing the cooking stove is a frosted glass surface, so that the light intensity emitted to the cooking stove is softer.

[0053] As Figure 10 shown, the connecting member 32 includes a connecting plate 321 and a connecting lug 322; the connecting plate 321 is connected to the glass plate 31, and the connecting plate 321 is connected to the range hood body 1 through the connecting lug 322. The connecting lug 322 passes through the smoke collecting hood 11 and is connected to the housing of the range hood body 1. The connecting plate 321 and the glass plate 31 are connected by screws or the like. The connecting plate 321 is used to increase the contact area between the connecting member 32 and the glass plate 31 to ensure the stability of the connection.

[0054] As Figures 3-5 shown, further, the driving assembly 4 includes a driving member 41 and a connecting rod 42; the driving member 41 is connected to the glass flap assembly 3 through the connecting rod 42 for driving the glass flap assembly 3 and driving the lighting assembly 2 to turn downward or downward relative to the range hood body 1. The connecting rod 42 is rotatably connected to the connecting lug 322. When the driving member 41 is started, the driving member 41 drives the connecting rod 42 to drive the connecting member 32, the glass plate 31 and the lighting assembly 2 to turn upward or downward relative to the range hood body 1.

[0055] For example, in the embodiment, the driving member 41 can be a DC motor, and is installed in the space formed between the smoke collecting hood 11 and the housing of the range hood body 1 to ensure the overall aesthetics of the range hood body 1. The driving member 41 is provided at the front end of the smoke collecting hood 11 to reduce the distance between the driving member 41 and the glass plate 31. One end of the connecting rod 42 passes through the smoke collecting hood 11 and is connected to the driving member 41, and the other end is rotatably connected to the connecting member 32. Since the connecting member 32 is connected to the glass plate 31, the driving member 41 can drive the connecting rod 42 to drive the connecting member 32 and the glass plate 31 to flip up or down relative to the front end face of the smoke collecting hood 11.

[0056] Usage process:

[0057] When lighting is required during the cooking process, the lighting lamp 22 lights up, and at the same time, the driving member 41 (such as a DC small motor) starts, driving the glass plate 31, the lamp housing 21, and the lighting lamp 22 to flip down relative to the front panel of the smoke collecting hood 11. When the flipping is in place, the light of the lighting lamp 22 is refracted into the glass plate 3 from one side of the glass plate 3 facing away from the cooking appliance, and then refracted out from the side of the glass plate 3 facing the cooking appliance and then shines on the cooking appliance to achieve cooking lighting.

[0058] When the lighting is not needed, the lighting lamp 22 is turned off, and the driving member 41 is reset, driving the glass plate 31, the lamp housing 21, and the lighting lamp 22 to flip up relative to the front panel of the smoke collecting hood 11 so that the back of the lighting lamp 22 directly faces the cooking appliance.
