Problems solved by technology

However, since the gas stove produces an open flame when it is working, the burning flame will interfere with the user's judgment of the color of the knob, and the user cannot accurately identify the current firepower / power
For stoves designed with more gears, it is not suitable to display firepower / power by color

Embodiment 1

[0044] Please refer to figure 1 , figure 1 It is a cross-sectional view of the operating device of the cooktop according to Embodiment 1 of the present invention. The operating device 2 includes a panel 21 , a rotating shaft 22 , a knob 23 and a light emitting element 24 . The rotating shaft 22 is at least partially located inside the panel 21 . The operating device 2 has at least two gear positions, and the gear position of the operating device 2 can be adjusted by turning the rotating shaft 22 . The knob 23 is at least partly located outside the panel 21 and sleeved on the rotating shaft 22 for driving the rotating shaft 22 to rotate. The light emitting element 24 is located inside the panel 21 .

[0045] The operating device 2 further includes a light guide member 25 connected to the rotating shaft 22 and driven by the rotating shaft 22 to rotate when the rotating shaft 22 rotates. The light guiding member 25 is located between the light emitting member 24 and the panel...

Embodiment 2

[0050] The same or corresponding structures of this embodiment and the first embodiment have the same or corresponding reference numerals, and their functions are also the same or similar, so details will not be repeated here, please refer to the corresponding description of the first embodiment. Different from Embodiment 1, the panel 21' of this embodiment has a light-transmitting region 300 and a fourth opaque region 304 surrounding the light-transmitting region 300. That is, the panel 21' is opaque except for the light-transmitting region 300, such as Figure 9 as shown, Figure 9 It is the front view of the panel of the second embodiment of the present invention. like Figure 10 as shown, Figure 10 It is a three-dimensional view of the light-emitting element of the second embodiment of the present invention. The light emitting surface 252' of the light-emitting element 25' in this embodiment has at least two light-transmitting gear marks 400, and the gear marks 400 ar...

Embodiment 3

[0053] The same or corresponding structures of this embodiment and the first embodiment have the same or corresponding reference numerals, and their functions are also the same or similar, so details will not be repeated here, please refer to the corresponding description of the first embodiment. like Figure 12 as shown, Figure 12 It is a cross-sectional view of the operating device of the cooktop according to the third embodiment of the present invention. The difference between this embodiment and the first embodiment lies in that the operating device of this embodiment further includes a light shield 26 for preventing the light from the light emitting element 24 from scattering to the panel 21 . Please refer to Figure 13 to Figure 15 , Figure 13 It is a three-dimensional view of the shading cover of Embodiment 3 of the present invention, Figure 14 is a three-dimensional view of the light guide in Embodiment 3 of the present invention, Figure 15 It is a cross-secti...

Abstract

The invention relates to an operation device of a stove and the stove. The operation device has at least two gear positions, comprises a panel, a rotary shaft, a rotary knob and a light-emitting part and further comprises a light guide part which is connected to the rotary shaft and rotates under the driving of the rotary shaft when the rotary shaft rotates, and the light guide part is located between the light-emitting part and the panel. The light guide part comprises a light incidence surface facing the light-emitting part and a light emergence surface facing the panel, and the light of the light-emitting part enters the light guide part through the light incidence surface and is emitted to the panel through the light emergence surface. One of the light emergence surface and the panel has at least two light-transmitting gear position marks, and the other has a light-transmitting area. When the rotary knob rotates to one gear position of the operation device, only one illuminated gear position mark is displayed on the panel.

Description

【Technical field】 [0001] The invention relates to an operating device for a cooker, in particular to an operating device for a cooker with a light-emitting element and a gear mark and a cooker with the operating device. 【Background technique】 [0002] For the luminous knobs on the existing cooker, the bright light generally only plays a decorative role, or simply uses the light on and off to display the on-off state of the cooker. This luminous knob conveys limited information to the user, and cannot display the current fire / power status of the cooker through bright light. There are also some knobs that can emit different colors of light to show different firepower / power of the cooker. However, since the gas cooker generates an open flame during operation, the burning flame interferes with the user's judgment of the color of the knob, and the user cannot accurately identify the current firepower / power. For cooktops designed with more gears, it is not suitable to display fi...
