Therefore, the liquid entering the interior of the knob assembly is prevented from flowing and spreading in the interior of the knob assembly.
the liquid discharging part 126 is arranged on the knob base 106, to allow the liquid entering into the liquid discharging cavity 122 to be discharged from the liquid discharging part 126.
the liquid is prevented from retaining in the liquid discharging cavity 122 for a long time, which ensures the dry environment inside the knob assembly, ensures that the liquid inside the liquid discharging cavity 122 is discharged by the knob assembly in time, and ensures the service life of the knob assembly.
the first liquid blocking part 144 and the second liquid blocking part 128 are arranged between the liquid discharging part 126 and the mounting groove 142.
the first liquid blocking part 144 and the second liquid blocking part 128 may block the liquid between the liquid discharging part 126 and the mounting groove 142. Therefore, the liquid discharged from the liquid discharging part 126 is prevented from entering into the mounting groove 142, which ensures the safety of use of the control module 162 arranged in the mounting groove 142.
each of the first liquid blocking part 144 and the second liquid blocking part 128 is an annular rib.
the control module 162 is located in a space defined by the first liquid blocking part 144.
the first liquid blocking part 144 is located in a space defined by the second liquid blocking part 128.
the knob body 116 is located at an outer periphery of the second liquid blocking part 128. In this way, there are at least two waterproof structures in a direction from the knob body 116 to the mounting groove 142.
the knob assembly may be transversely arranged after being mounted to the electrical apparatus. Therefore, the design that each of the first liquid blocking part 144 and the second liquid blocking part 128 is an annular rib may ensure the waterproof effect of the knob assembly in all directions, and may realize the all-round waterproofness of the knob assembly.
the knob assembly further includes a lid plate 118 and a fourth liquid blocking part 132.
the lid plate 118 is capped on the display module 120, to enable the lid plate to play a certain role of protecting the display module 120. Therefore, on the one hand, the display module 120 is prevented from being bumped, and on the other hand, the water is prevented from entering the display module 120.
the lid plate 118 may be decorated with patterns or colors, to ensure a final presentation state of the light emitted from the display module 120.
the gap 124 is formed between the fourth liquid blocking part 132 and the knob body 116.
each of the third liquid blocking part 130 and the fourth liquid blocking part 132 is located between the liquid discharging cavity 122 and the display module 120, and the third liquid blocking part 130 and the fourth liquid blocking part 132 are configured to block the liquid between the liquid discharging cavity 122 and the display module 120, and to further block the liquid entering into the liquid discharging cavity 122 from flowing to the display module 120. Therefore, the service life of the display module 120 is ensured.
the knob assembly further includes a module support 108.
the module support 108 is arranged on the control module 162, and the display module 120 is arranged on the module support 108, to ensure the stable mounting of the display module 120.
the fourth liquid blocking part 132 is provided with a first snap 148, and a lid body of the lid plate may be mounted on the module support 108 by the first snap 148, to ensure the stable connection of the lid body.
the first snap 148 is arranged to enable the fourth liquid blocking part 132 to have the functions of blocking the liquid and mounting the lid body. Therefore, the separate design of a drainage structure, a liquid blocking structure and a mounting structure is avoided, the overall structure of the knob assembly is simplified, and the miniaturization design of the knob assembly is realized.
the module support 108 is provided with a flange 146.
the flange 146 is capped above the third liquid blocking part 130, and is at least located between the third liquid blocking part 130 and the knob body 116.
