For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0040] like Figure 1 As shown, the auxiliary lamp structure 100 provided by the utility model is applied to the range hood and used in conjunction with the main lamp 200. The main lamp 200 is fixed relative to the smoke hood 400 and the irradiation angle remains unchanged, while the irradiation angle of the auxiliary lamp structure 100 is adjustable.
[0041] Specifically, Figure 2 As shown, the auxiliary lamp structure 100 includes: a lamp body 110, a first driving module and a second driving module.
[0042] The first driving module is connected to the lamp body 110, and is used to drive the lamp body 110 to rotate on the first plane. The second driving module is connected to the first driving module, and is used to drive the first driving module and the lamp body 110 to rotate together on the second plane, and the first plane and the second plane are set at an angle. Taking the working state as an example, the second plane can be a horizontal plane, and the first plane can be a vertical plane extending in the left and right directions, and the first plane and the second plane are perpendicular, wherein the first driving module can rotate at an angle of 0-360°, and the second driving module can drive at an angle range of 0-120°.
[0043] According to the concentration distribution of oil smoke, by arranging the lamp body 110 on the first driving module and the second driving module, the irradiation direction of the lamp body 110 can be changed on the first plane and the second plane, thereby increasing the illumination range of the lamp body 110.
[0044] Specifically, Figure 2 - Figure 6 As shown, the first driving module includes a first motor 140, the first motor 140 includes a first driving shaft 120, and an axial hole is provided on the lamp body 110. During assembly, the lamp body 110 is installed by plugging and unplugging, and the first driving shaft 120 is inserted into the axial hole. By setting the axial hole as a non-circular hole, an assembly section 124 extending from its top to the housing direction of the first motor 140 is provided on the first driving shaft 120, and the shape of the cross section of the assembly section 124 is consistent with the cross section of the large and small axial holes, so that the axial hole of the lamp body 110 can be inserted into the assembly section 124 from the top of the first driving shaft 120, and the non-circular hole cooperates with the assembly section 124 to prevent the lamp body 110 from rotating relative to the first driving shaft 120. Specifically, a section 122 is provided at the side wall of the first driving shaft 120, so that the cross section of the assembly section 124 forms a notched circle. In addition to the above-mentioned shape, the shape of the cross section of the assembly section 124 can also be rectangular, triangular, etc.
[0045] like Figure 4As shown, the first driving shaft 120 includes a transition section 125 connected to the assembly section 124, the transition section 125 is connected to the main body of the first motor 140, the cross section of the transition section 125 may be circular, and there is an upper step structure 123 between the assembly section 124 and the transition section 125 from the assembly section 124 to the transition section. A stopper 121 is also provided on the assembly section 124. Specifically, an assembly hole is provided on the section 122 of the assembly section 124, and the stopper 121 is installed in the assembly hole. The stopper 121 may include a spring and a lock pin, and the lock pin may enter the assembly hole under the action of an external force, so that the lamp body 110 passes over the position of the stopper 121. Then, it may extend from the assembly hole under the action of the spring. The stopper 121 and the upper step structure 123 are respectively stopped at opposite sides of the lamp body 110 along the first driving shaft 120, thereby preventing the lamp body 110 from moving along the first driving shaft 120.
[0046] The first driving module further includes a base 130 , which is in a truncated cone shape. The first motor 140 is connected to the front side of the base 130 , which is the side facing the cooker in this embodiment.
[0047] like Figure 2 As shown, the second driving module includes a second motor 150, and the second motor 150 includes a second driving shaft 160, and the end surface of the second driving shaft 160 is connected to the back surface of the base 130. Among them, the second driving module may include a second motor 150, the main body of the second motor 150 and the smoke hood 400 may be connected by screws, and the second output shaft of the second motor 150 may be arranged vertically.
[0048] The end surface of the second driving shaft 160 has a threaded hole, and the number of the threaded holes can be but is not limited to two. The base 130 is provided with a mounting hole 131, and the auxiliary lamp structure 100 further includes a threaded member 170 passing through the mounting hole 131 and connected to the threaded hole. During installation, the mounting hole 131 is aligned with the threaded hole, and the threaded member 170 is inserted and tightened from bottom to top, so that the base 130 and the second driving shaft 160 can be connected.
[0049] like Figure 6 As shown, in order to achieve accurate positioning of the mounting hole 131 and the threaded hole and facilitate assembly, the end face of the second drive shaft 160 and the back face of the base 130 are respectively provided with positioning structures. Positioning can be achieved by docking the concave and convex structures. Specifically, the positioning structure includes a socket provided on the end face of the second drive shaft 160 and a plug 161 provided on the back face of the base 130. During installation, the plug 161 is inserted into the socket to achieve automatic alignment of the mounting hole 131 and the threaded hole. In order to distinguish the mounting hole 131 from the socket, the socket can be set as a rectangular hole.
[0050] The lamp body 110 may be a fog-penetrating high-intensity lamp.
[0051] The range hood provided by the utility model comprises a thermal imaging device 300, a controller and the auxiliary lamp structure 100. The controller can adjust the light output angle of the auxiliary lamp structure 100 according to the detection result of the thermal imaging device 300.
[0052] The temperature data of the stove and pot is detected by the thermal imaging device 300, the corresponding color characteristics are determined, and a temperature cloud map is generated. The controller performs image processing and analysis on the temperature cloud map, extracts the color characteristic values of the pixels, and divides the cloud map matrix coordinates according to the pixel positions. The pixel color characteristics are compared with the preset color characteristics with the highest thermal value, and the coordinates of the pixel with the highest thermal value are output. Finally, the pixel matrix coordinate data is converted into the angle data of the auxiliary light structure 100, and the auxiliary light rotation control is realized through the first drive module and the second drive module.
[0053] The smoke collecting hood 400 is also provided with a filter located in front of the main lamp 200 and the auxiliary lamp structure 100 to block oil stains.
[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
