[0036] This embodiment discloses a backlight source assembly and a range hood including the backlight source assembly, which are used to remove the fumes generated during cooking. Figures 1 to 3 As shown, the range hood includes a box assembly 3, a smoke collecting chamber, a backlight assembly and a control device. An air inlet channel 31 is formed inside the box assembly 3. A fan (not shown) can generate negative pressure in the air inlet channel 31. The control device is connected to the backlight assembly.

[0037] In this embodiment, the control device can be a centralized or distributed controller. For example, the controller can be a single single-chip microcomputer or a distributed plurality of single-chip microcomputers. The single-chip microcomputer can run a control program to control the backlight source assembly to realize its function.

[0038] The smoke collecting chamber is connected to the box assembly 3, and the backlight assembly is mounted on the smoke collecting chamber. In this embodiment, the smoke collecting chamber includes a top smoke collecting chamber plate 41 disposed above the cooker (not shown) and a side smoke collecting chamber plate 42 disposed on the side of the cooker. The backlight assembly is mounted on the side smoke collecting chamber plate 42 and can project light on the side smoke collecting chamber plate 42.

[0039] like Figures 4 to 6 As shown, the backlight source assembly includes a light source base 1 and a lamp body 2, the light source base 1 is connected to the mounting surface, and the lamp body 2 is arranged on the light source base 1. In this embodiment, the mounting surface is a smoke collecting chamber, the light source base 1 is connected to the smoke collecting chamber, and the lamp body 2 is arranged toward the smoke collecting chamber and can project light onto the smoke collecting chamber. Of course, when the mounting surface is a wall or other structure, the lamp body 2 can also project light toward the wall or other structure.

[0040] The control device is connected to the lamp body 2, and the lamp body 2 can adjust the light brightness and / or light color according to the change of the range hood gear. The brightness and color of the light emitted by the lamp body 2 are not specifically limited, and it is sufficient to make the gear of the range hood explicit to improve the interactive experience between the range hood and the user. The user can know the current gear of the range hood by seeing the light emitted by the lamp body 2, without lighting up the touch screen to search, and the user experience is better.

[0041] In this embodiment, when the range hood is at the maximum gear, the light emitted by the lamp body 2 is the brightest and the color is red; when the range hood is at the middle gear, the light emitted by the lamp body 2 is the second brightest and the color is yellow; when the range hood is at the minimum gear, the light emitted by the lamp body 2 is the smallest and the color is white. When the range hood is at the maximum gear and the oil smoke concentration is still increasing, the red light emitted by the lamp body 2 can flash intermittently.

[0042] On the basis of the above structure, the range hood further includes a smoke guide plate, and a connecting piece for supporting the smoke guide plate is provided on the light source base 1, and the smoke guide plate is connected to the smoke collecting chamber through the light source base 1. Figures 1 to 3 As shown, after assembly, the light source base 1 separates the smoke guide plate and the smoke collecting chamber by a distance, and a negative pressure channel (not shown) connected to the air inlet channel 31 is formed between the smoke guide plate and the smoke collecting chamber, and the oil fume gas can enter the air inlet channel 31 through the negative pressure channel.

[0043] In the present embodiment, the smoke guide plate includes a top smoke guide plate 51 and a side smoke guide plate 52. The top smoke guide plate 51 is connected to the top smoke collecting cavity plate 41, and the side smoke guide plate 52 is connected to the side smoke collecting cavity plate 42 through the light source base 1. It can gather the oil smoke drifting to the side and the oil smoke rising upward, so as to absorb the oil smoke more thoroughly.

[0044] The specific structure of the connecting piece is not limited, as long as it can connect the smoke guide plate to the smoke collecting chamber. Figure 7 and Figure 8 As shown, a buckle 53 is provided on the side smoke guide plate 52, and a contact column fixing seat 11 is provided on the light source base 1. The buckle 53 can be inserted into the contact column fixing seat 11, thereby preventing the side smoke guide plate 52 from moving away from the light source base 1 in the horizontal direction. In this embodiment, the contact column fixing seat 11 is arranged on the end surface of the light source base 1, so that the buckle 53 can be inserted from top to bottom ( Figure 8 The straight line with an arrow in the middle shows the installation direction of the side smoke guide plate 52) and the collision column fixing seat 11, which is more convenient to use.

[0045] The specific structures of the collision column fixing seat 11 and the buckle 53 are not limited, and the collision column fixing seat 11 and the buckle 53 in the prior art can be used. In this embodiment, the collision column fixing seat 11 includes a blind hole (not shown) and a stopper 111 disposed in the blind hole, and the buckle 53 is provided with a protrusion (not shown) that matches the stopper 111. The stopper 111 is connected to an elastic member (not shown), and the elastic member pushes the stopper 111 toward the axis of the blind hole.

[0046] When the buckle 53 is ready to be inserted into the blind hole, the protrusion on the buckle 53 can press the stopper 111 outward; after the buckle 53 is completely inserted into the blind hole, the stopper 111 is reset under the action of the elastic member. The stopper 111 is stuck on the protrusion on the buckle 53, which can prevent the buckle 53 from accidentally withdrawing from the collision column fixing seat 11. When removing the side smoke guide plate 52, the buckle 53 can be removed from the collision column fixing seat 11 by simply pulling the stopper 111 in the direction of the compressed elastic member or using the protrusion on the buckle 53 to press the stopper 111 outward.

[0047] Of course, it is also feasible to set the buckle 53 on the light source base 1 and the collision column fixing seat 11 on the side smoke guide plate 52. The buckle 53 and the collision column fixing seat 11 can also be used together to achieve a stable connection between the smoke guide plate and the smoke collecting chamber. In this structure, the buckle 53 is set on the end surface of the light source base 1, which is easy to disassemble and assemble, and can limit the relative movement of the light source base 1 and the side smoke guide plate 52 in the horizontal direction.

[0048] On the basis of the above structure, a hook 54 is provided on the side smoke guide plate 52, and a limiting column 12 is provided on the light source base 1. The hook 54 can be hung on the limiting column 12, which can not only limit the relative movement of the side smoke guide plate 52 and the light source base 1 in the horizontal direction, but also support the side smoke guide plate 52, so that the side smoke guide plate 52 can be stably installed on the side smoke collecting chamber plate 42 through the light source base 1.

[0049] The limiting column 12 is arranged on the side of the light source base 1, and the hook 54 is arranged on the back side of the side smoke guide plate 52 (the side facing the side smoke collecting chamber plate 42). The hook 54 is easier to hang on the limiting column 12, and the disassembly and assembly efficiency is high. After assembly, the limiting column 12 and the hook 54 will not be exposed on the front side of the side smoke guide plate 52 (the side facing the user), and the appearance is more beautiful.

[0050] Of course, it is also feasible to set the hook 54 on the light source base 1 and the limiting column 12 on the side smoke guide plate 52 without affecting the connection between the hook 54 and the limiting column 12. The side smoke guide plate 52 can also be stably installed on the side smoke collecting chamber plate 42 through the light source base 1.

[0051] In order to make the force on the side smoke guide plate 52 more balanced, at least two backlight source assemblies are symmetrically arranged on the smoke collecting chamber. In this embodiment, two backlight source assemblies are arranged on the smoke collecting chamber as an example for description. Specifically, based on the vertical center line of the side smoke collecting chamber plate 42, the two light source bases 1 are respectively located on both sides of the vertical center line, and the left and right ends of the side smoke guide plate 52 in the horizontal direction are respectively connected to the light source base 1. Through the simultaneous support of the two light source bases 1, the structure of the side smoke guide plate 52 after installation is more stable.

[0052] The limiting column 12 is arranged on the side of the light source base 1 facing the other light source base 1. That is, the light source bases 1 are arranged on the left and right sides of the side smoke collecting chamber plate 42, respectively. The limiting column 12 arranged on the left light source base 1 is located on the right side of the light source base 1, and the limiting column 12 arranged on the right light source base 1 is located on the left side of the light source base 1. After assembly, the limiting column 12 cannot be seen from the side of the range hood, and the appearance is more beautiful; the light source base 1 can limit the hook 54, preventing the hook 54 from sliding along the limiting column 12 until it is separated from the limiting column 12, and the installation structure of the side smoke guide plate 52 is more stable.

[0053] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention.
