Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and in particular to a high-efficiency and energy-saving range hood. Background Technology

[0002] With the rapid development of modern kitchen appliance technology, the range hood, as a core piece of equipment in home and commercial kitchens, has evolved from a simple smoke extraction tool to one that is intelligent and energy-efficient.

[0003] Current range hoods use fans and other mechanisms to circulate air and draw cooking fumes into the device. While this method is effective, it doesn't account for the fact that range hoods typically reduce the noise level of the fan blades to optimize the user experience. If the user doesn't turn the device off promptly after use, the low noise level can cause the device to continue operating even when there's no fumes to draw in, resulting in unnecessary energy waste.

[0004] Therefore, a high-efficiency and energy-saving range hood is proposed. Utility Model Content

The cleaning rod extends into the interior of the detection tube through the openings and contacts the detection head.

[0008] Preferably, a filter screen is fixedly installed inside the filter box.

[0009] Preferably, a second motor is fixedly installed on the right side of the drive box, a worm gear is rotatably installed inside the drive box, the output end of the second motor extends into the drive box and is fixedly connected to the worm gear, two sets of third rotating rods are rotatably installed inside the drive box and are distributed left and right, a turbine is fixedly installed on the third rotating rod, the turbine is threadedly connected to the worm gear, and one end of the third rotating rod extends into the exhaust box and is fixedly installed with an oil fume fan.

[0010] Preferably, a first motor is fixedly installed on the top of the detection tube, and a second rotating rod is fixedly installed inside the detection tube from the output end of the first motor. A detection fan blade is fixedly installed at one end of the second rotating rod.

[0012] Preferably, one end of the second transmission rod passes through the transmission pipe and is fixedly connected to the first rotating rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This high-efficiency and energy-saving range hood, through the combined use of a first motor, a second rotating rod, a detection fan blade, a heat detector, and a detection head, enables the device to control the first motor to start and drive the detection fan blade to rotate, so that the detection fan blade can drive the oil fumes in the exhaust box to be diverted and enter the detection tube. The setting of the detection head enables the heat detector to detect the heat present in the oil fumes. When the heat detector cannot detect heat, it means that the oil fumes have been completely extracted. At this time, the heat detector sends a signal to the control panel, thereby controlling the device to stop running, preventing the device from running dry, thus effectively reducing energy waste and improving the energy-saving performance of the device.

[0015] (2) This high-efficiency and energy-saving range hood, through the combined use of a first mounting frame, a second mounting frame, a slider, a rotating block, a first rotating rod, and a cleaning rod, enables the device to control the second motor to start and drive the rotating block to rotate. Through the sliding arrangement between the first mounting frame, the second mounting frame, and the slider, the rotating block can drive the second mounting frame to reciprocate longitudinally when rotating, thereby enabling it to drive the cleaning rod to move and clean the surface of the detection head. This prevents the grease in the fumes from forming an oil film on the surface of the detection head, which would reduce the detection accuracy of the heat detector and improve the practicality of the device.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Please see Figure 1-4This utility model provides a technical solution: a high-efficiency and energy-saving range hood, including a filter box 1, a control panel 10 fixedly installed on the front side of the filter box 1, an exhaust box 2 fixedly installed on the top of the filter box 1, a drive box 3 fixedly installed on the top of the exhaust box 2, a detection tube 5 fixedly installed on the left side of the exhaust box 2 and communicating with the interior of the exhaust box 2, an exhaust pipe 7 fixedly installed on the rear side of the exhaust box 2, a heat detector 20 fixedly installed on the left inner wall of the detection tube 5, a detection head 21 fixedly installed at the detection end of the heat detector 20, a transmission box 6 fixedly installed on the left side of the detection tube 5, a transmission pipe 4 fixedly installed on the left side of the drive box 3, a cleaning mechanism 8 provided inside the transmission box 6, the cleaning mechanism 8 including a first mounting frame 801 fixed inside the transmission box 6, a second mounting frame 802, a slider 803, a rotating block 804, a first rotating rod 805 and a cleaning rod 806, and so on. The detection head 21 enables the heat detector 20 to detect the heat present in the fumes. When the heat detector 20 detects no heat, it means that the fumes have been completely extracted. At this time, the heat detector 20 sends a signal to the control panel 10, thereby controlling the device to stop operating and preventing the device from running idle. This effectively reduces energy waste and improves the energy-saving performance of the device. By controlling the second motor 13 to start and drive the rotating block 804 to rotate, the sliding arrangement between the first mounting frame 801, the second mounting frame 802 and the slider 803 allows the rotating block 804 to drive the second mounting frame 802 to move back and forth longitudinally when rotating. This allows the cleaning rod 806 to move and clean the surface of the detection head 21, preventing the grease in the fumes from forming an oil film on the surface of the detection head 21, which would reduce the detection accuracy of the heat detector 20 and improve the practicality of the device.

[0024] like Figure 2 As shown, a filter screen 17 is fixedly installed inside the filter box 1, which enables the device to initially filter oil fumes and improves the practicality of the device.

[0025] like Figure 2 and Figure 3 As shown, a second motor 13 is fixedly installed on the right side of the drive box 3. A worm gear 14 is rotatably installed inside the drive box 3. The output end of the second motor 13 extends into the drive box 3 and is fixedly connected to the worm gear 14. Two sets of third rotating rods 22 are rotatably installed inside the drive box 3 and are distributed left and right. A turbine 23 is fixedly installed on the third rotating rod 22 and is threadedly connected to the worm gear 14. One end of the third rotating rod 22 extends into the exhaust box 2 and is fixedly installed with a fume fan 24, so that the device can draw external fumes into the exhaust box 2 and discharge them from the exhaust pipe 7, thus improving the practicality of the device.

[0026] like Figure 2As shown, a first motor 9 is fixedly installed on the top of the detection tube 5. The output end of the first motor 9 extends into the interior of the detection tube 5 and a second rotating rod 11 is fixedly installed thereon. A detection fan blade 12 is fixedly installed at one end of the second rotating rod 11, so that the device can divert the oil fumes inside the exhaust box 2 into the interior of the detection tube 5, thereby facilitating the heat detector 20 to detect them and improving the practicality of the device.

[0027] like Figure 2 and Figure 4 As shown, one end of the worm gear 14 extends into the interior of the transmission pipe 4 and is fixedly installed with a first transmission rod 15. A second transmission rod 19 is rotatably installed inside the transmission pipe 4. Both the first transmission rod 15 and the second transmission rod 19 are fixedly installed with transmission wheels 16. A transmission belt 18 is sleeved on the transmission wheel 16 and the transmission wheel 16 is configured to transmit power through the transmission belt 18. One end of the second transmission rod 19 passes through the transmission pipe 4 and is fixedly connected to the first rotating rod 805. This allows the device to simultaneously drive the fume fan 24 and the rotating block 804 to rotate through a set of second motors 13, reducing the energy consumption of the device and improving its energy-saving performance.

[0028] Working Principle: During use, when fume extraction is needed, the second motor 13 is activated, driving both sets of fume extraction fans 24 via the worm gear 14 and turbine 23. This draws the fumes into the extraction box 2, where the filter 17 provides initial filtration. The extracted fumes are then discharged through the exhaust pipe 7. Simultaneously, the first motor 9 is activated, driving the detection fan blades 12 via the second rotating rod 11. This diverts the fumes into the detection tube 5, where the heat detector 20 detects the heat in the fumes via the detection head 21. When the detection head 21 detects a temperature drop inside the detection tube 5, it indicates that no fumes need to be absorbed. After a period of time, the heat detector 20 transmits a signal to the control panel 10. The signal, and then the automatic control device shuts down to reduce the power consumption of the device. When the worm gear 14 rotates, it can simultaneously drive the first transmission rod 15 to rotate. Through the setting of the transmission wheel 16 and the transmission belt 18, the first transmission rod 15 can drive the second transmission rod 19 to rotate, and then the second transmission rod 19 can drive the first rotating rod 805 to rotate. The first rotating rod 805 can drive the rotating block 804 to rotate. Since one end of the first rotating rod 805 is fixedly connected to the right side of the center of the rotating block 804, when the rotating block 804 rotates through the detection tube 5, it can drive the slider 803 to reciprocate laterally inside the second mounting frame 802, and can also drive the second mounting frame 802 to reciprocate longitudinally inside the first mounting frame 801, thereby driving the cleaning rod 806 to move, so as to reciprocate the hanging cleaning of the detection head 21.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
