[0002] In the prior art, a control box is usually provided on the inner surface of the flap of the range hood, and a control device for controlling the operation of the range hood or the operation of the lighting lamp is installed in the control box. The electrical wires of the control device pass through the control box and extend into the smoke collecting chamber of the range hood. In this structure, when the flap opens the smoke inlet, the end of the electrical wire connected to the control device will be directly exposed to the outside of the range hood, which not only affects the appearance but also easily causes damage to the electrical wire.

[0003] In order to protect the electric wires, the prior art usually also provides a wire box, which is arranged on the flap, and one end of the electric wire connected to the control device is passed through the wire box, thereby preventing the electric wires from being directly exposed to the outside of the range hood. However, this structure can only protect a small section of the electric wire close to the control device. Although the other part of the electric wire will not move to the outside of the range hood during the opening and closing of the flap, this part of the electric wire is located in the smoke collecting chamber for a long time and is extremely susceptible to pollution and corrosion by the oil smoke in the smoke collecting chamber.

[0037] Reference Figures 1 to 9 In one embodiment of the utility model, a range hood is provided, comprising a smoke collecting hood 100, a partition assembly and a wire box 150. The smoke collecting hood 100 has a smoke collecting chamber 110, a front plate 120 of the smoke collecting hood 100 is provided with a smoke inlet 121 connected to the smoke collecting chamber 110, a flap 130 capable of opening or closing the smoke inlet 121 is rotatably mounted on the smoke collecting hood 100, a control box 140 is arranged on the inner surface of the flap 130, and a control device is installed in the control box 140. The partition assembly is installed in the smoke collecting chamber 110 and is located on one side of the smoke inlet 121. The partition assembly divides the smoke collecting chamber 110 into a mutually independent smoke inlet area 111 and an isolation area 112, and the smoke inlet area 111 is connected to the smoke inlet 121. The wire box 150 is installed on the inner surface of the flap 130, and the wire box 150 has a wire passage 151 connected to the control box 140. The wire box 150 is movably disposed in the smoke hood 100 and extends to the isolation area 112 . When the flap 130 opens the smoke inlet 121 , one end of the wire channel 151 away from the control box 140 is connected to the isolation area 112 .

[0038] By adopting the range hood of the embodiment of the utility model, the smoke collecting chamber 110 is divided into a mutually independent smoke inlet area 111 and an isolation area 112 by a partition component in the smoke collecting hood 100, and the smoke can flow into the smoke inlet area 111 through the smoke inlet port 121 and be discharged from the smoke inlet area 111. The wire box 150 is movably arranged in the smoke collecting hood 100 and extends to the isolation area 112. When the flap 130 opens the smoke inlet port 121, the wire passage 151 of the wire box 150 is connected with the isolation area 112, so that the control device The electric wire passes through the control box 140 and enters the wire passage 151 of the wire box 150, and extends from the wire passage 151 to the isolation area 112 of the smoke collecting chamber 110. In this structure, the wire box 150 can protect the electric wire between the flap 130 and the smoke collecting hood 100. Since the partition plate 160 can prevent oil smoke from entering the isolation area 112, the structure can also protect the electric wire extending into the smoke collecting chamber 110, greatly reducing the risk of the electric wire being corroded by oil smoke pollution.

[0039] Reference Figures 1 to 9 In some embodiments, the smoke inlet 121 includes two smoke inlet holes 123 opened on the front plate 120. The two smoke inlet holes 123 are arranged side by side, which can facilitate the fume extraction for two independent burners and help improve the fume extraction efficiency.

[0040] Reference Figures 1 to 9 In some embodiments, the front plate 120 is provided with a clearance hole 122 connected to the isolation area 112 , and the wire box 150 has an arc segment 152 movably passed through the clearance hole 122 , and the center of the arc segment 152 is coaxially arranged with the rotation axis of the flap 130 .

[0041] By adopting the above structure, an arc segment 152 is arranged on the wire box 150, and the arc segment 152 is inserted into the clearance hole 122. When the flap 130 is flipped relative to the smoke hood 100 to open or close the smoke inlet 121, the arc segment 152 flips with the flap 130, and since the center of the arc segment 152 is coaxially arranged with the rotation axis of the flap 130, the arc segment 152 can rotate coaxially with the flap 130, thereby allowing the arc segment 152 to move smoothly in the clearance hole 122, thereby avoiding friction, collision or even jamming between the wire box 150 and the smoke hood 100, thereby ensuring the normal flipping and opening and closing of the flap 130.

[0042] In addition, by adopting the above-mentioned structure, the clearance hole 122 can be set to be compatible with the shape of the wire box 150, and there is no need to set the clearance hole 122 too large to avoid friction and jamming between the wire box 150 and the periphery of the clearance hole 122. This can not only ensure the normal opening and closing of the flap 130, but also further prevent external oil smoke from flowing into the isolation area 112 of the smoke collecting chamber 110 through the clearance hole 122.

[0043] Reference Figures 1 to 9 In some embodiments, a wire sleeve can be set in the clearance hole 122 to block the gap between the outer peripheral wall of the wire box 150 and the inner peripheral edge of the clearance hole 122, thereby further preventing external oil smoke from flowing into the isolation area 112 of the smoke collecting chamber 110 through the clearance hole 122.

[0044] Reference Figures 1 to 9 In some embodiments, the wire box 150 is partially inserted into the control box 140 , and a seal is provided between the wire box 150 and the control box 140 .

[0045] By adopting the above structure, the wire box 150 is partially inserted into the control box 140, so that the electrical wires of the control device can directly extend from the control box 140 to the wire channel 151 of the wire box 150, thereby better protecting the electrical wires. In addition, the setting of the seal can seal the gap between the wire box 150 and the control box 140, preventing external oil smoke from flowing into the control box 140 through the gap between the wire box 150 and the control box 140 and causing pollution and corrosion to the control device and the electrical wires.

[0046] It is understandable that the sealing member may be a flexible member such as a rubber member, a silicone member, etc., and the present invention does not make any specific limitation on this.

[0047] Reference Figures 1 to 9In some embodiments, the control box 140 has an outwardly extending installation channel 141 , the wire box 150 is inserted into the installation channel 141 , and the seal is located between the outer peripheral wall of the wire box 150 and the inner peripheral wall of the installation channel 141 .

[0048] By adopting the above structure, the wire box 150 is inserted into the installation channel 141 of the control box 140, which makes it easy to install and fix the wire box 150, and also facilitates the protection and isolation of the electrical wires. The structure is simple and easy to assemble.

[0049] Reference Figures 1 to 9 In some embodiments, the wire box 150 specifically includes a box body and a cover body, and the wire passage 151 is formed by the box body and the cover body being mutually enclosed and defined, and the structure is simple and easy to process. It can be understood that the cover body can be connected to the box body by a snap-fit ​​structure, and the structure is simple and easy to disassemble and assemble. Of course, in addition to this, the cover body can also be threadedly connected to the box body by fasteners such as screws and bolts, and the utility model does not make specific limitations on this.

[0050] Reference Figures 1 to 9 In some embodiments, the partition assembly includes two partition plates 160 , which are arranged on both sides of the smoke inlet 121 , the smoke inlet area 111 is located between the two partition plates 160 , and the isolation area 112 is located on two opposite sides of the smoke inlet area 111 .

[0051] By adopting the above structure, by setting the partition component to a structure of two partition plates 160, the two partition plates 160 are arranged correspondingly on both sides of the smoke inlet 121, so that the smoke inlet area 111 is located between the two partition plates 160, and the isolation area 112 is located on the opposite sides of the smoke inlet area 111. In this structure, the partition plates 160 can not only separate the oil smoke outside the isolation area 112 to protect the electrical wires in the isolation area 112, and reduce the risk of the electrical wires being contaminated and corroded by the oil smoke, in addition, the structure arranges the partition plates 160 on both sides of the smoke inlet 121, and can also play the role of smoke collection and diversion, concentrating the oil smoke entering from the smoke inlet 121 in the smoke inlet area 111, and guiding the oil smoke to flow upward and be discharged, so that the entire process of absorbing oil smoke is smoother, and the oil smoke absorption efficiency of the range hood is greatly improved.

[0052] Reference Figures 1 to 9 In some embodiments, the isolation area 112 is equipped with a driving device 170, the driving device 170 and the wire box 150 are located on the same side of the smoke inlet area 111, the driving device 170 is transmission-connected with a connecting rod assembly 180, the connecting rod assembly 180 movably passes through the front plate 120 and is connected to the flap 130, and the driving device 170 can drive the flap 130 to flip relative to the smoke hood 100 through the connecting rod assembly 180.

[0053] In the above structure, by installing the drive device 170 in the isolation area 112 of the smoke collecting chamber 110, the drive device 170 can be protected to prevent the drive device 170 from being damaged due to pollution and corrosion by oil smoke. By arranging the drive device 170 and the wire box 150 on the same side of the smoke inlet area 111, it is convenient to connect the electrical wires of the control device to the control device so as to control the operation of the drive device 170.

[0054] Reference Figures 1 to 9 In some embodiments, a wind cabinet 200 is installed on the top of the smoke hood 100, and the wind cabinet 200 is connected to the smoke inlet area 111; an electrical box 220 is installed on the top of the wind cabinet 200, and a partition plate 160 located on the side of the smoke inlet area 111 close to the wire box 150 is provided with a threading hole 161, and a sealing sleeve 162 is provided in the threading hole 161. A threading tube (not shown in the figure) is provided in the smoke inlet area 111, and one end of the threading tube is connected to the threading hole 161, and the other end extends upward to be connected to the electrical box 220.

[0055] In the above structure, by opening a threading hole 161 on the partition plate 160, and setting a threading tube connected to the threading hole 161 in the smoke inlet area 111, the threading tube is extended upward to be connected to the electrical box 220, so that the electric wires in the partition area can be extended upward through the threading tube to be electrically connected to the electrical components in the electrical box. The setting of the threading tube can prevent the electric wires from being polluted and corroded by the oil smoke in the smoke inlet area 111 and the wind cabinet 200, and more comprehensively shield and protect the electric wires. By setting a sealing sleeve 162 in the threading hole 161, the sealing sleeve 162 can seal the gap between the outer peripheral wall of the threading tube and the inner peripheral edge of the threading hole 161, so that the oil smoke in the smoke inlet area 111 can be prevented from flowing into the partition area through the threading hole 161 and causing pollution and corrosion to the electric wires, the drive device 170 and other parts in the partition area.

[0056] Reference Figures 1 to 11 In some embodiments, the partition plate 160 is provided with a plurality of noise reduction holes 163 , and a first noise reduction member 164 covering the noise reduction holes 163 is disposed on the surface of the partition plate 160 .

[0057] Since the fan of the range hood is prone to generate noise when it is working, by adopting the above structure, a plurality of noise reduction holes 163 are provided on the partition plate 160. When the noise generated by the fan passes through the noise reduction holes 163, pressure is generated and the sound frequency is changed, thereby achieving a certain noise reduction effect. By arranging a first noise reduction member 164 covering the noise reduction holes 163 on the surface of the partition plate 160, the noise passing through the noise reduction holes 163 can be absorbed, thereby greatly reducing the noise generated by the range hood when it is working. It can be seen that by adopting the above structure, not only can the effect of gathering and guiding smoke be achieved and the efficiency of oil smoke absorption be improved, but also the effect of vibration reduction and noise reduction can be achieved, thereby reducing the noise generated by the range hood when it is working.

[0058] It can be understood that the first noise reduction structure can specifically adopt noise reduction cotton, noise reduction board, noise reduction particles or other structures that can absorb noise to achieve noise reduction effect, and the present invention does not make specific limitations on this.

[0059] In some embodiments, the diameter of the noise reduction hole 163 is 2.0 mm-2.6 mm.

[0060] In the above structure, by setting the diameter of the noise reduction hole 163 to 2.0 mm-2.6 mm, the partition assembly can have a better noise reduction effect.

[0061] It is understandable that the diameter of the noise reduction hole 163 can be specifically set to 2.0 mm, 2.1 mm, 2.3 mm, 2.5 mm, 2.6 mm, etc., and the present invention does not make any specific limitation on this.

[0062] In some embodiments, in order to achieve better shock-absorbing and noise-reducing effects, the through-hole ratio of the noise-reducing holes 163 provided on the partition plate 160 may be set to be less than or equal to 40%.

[0063] Reference Figures 1 to 9 In some embodiments, the front edge of the partition plate 160 abuts against one side edge of the smoke inlet 121, the rear edge of the partition plate 160 abuts against the rear plate of the smoke hood 100, the lower edge of the partition plate 160 abuts against the bottom plate of the smoke hood 100, and the upper edge of the partition plate 160 abuts against one side edge of the lower end of the wind cabinet 200.

[0064] By adopting the above structure, the front edges of the two partition plates 160 are in contact with the opposite side edges of the smoke inlet 121, and the two partition plates 160 are extended upward to the upper side edges to abut against the opposite side edges of the lower end of the wind cabinet 200, thereby achieving a better smoke collection effect, concentrating the oil smoke in the smoke inlet area 111, and guiding the oil smoke to flow upward into the wind cabinet 200 and finally be discharged from the air outlet of the fan assembly 210, thereby avoiding the situation where the oil smoke directly hits the top wall of the smoke collecting chamber 110 and rebounds to form a vortex, making the entire oil smoke extraction process of the range hood smoother.

[0065] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
