Description

Technical Field

[0001] The present application relates to the technical field of small household appliances, and in particular to a cooking utensil. Background Art

[0002] In some cooking utensils with knobs, such as electric grill pans, a translucent light-transmitting ring is set around the knob. After the LED light is lit inside the knob, light will be radiated around the light-transmitting ring, thus serving as a power indicator and decoration. However, since the internal LED lights are independent lamp beads, the area on the light-transmitting ring facing the LED light is relatively bright, while the area not facing the LED light is relatively dark, resulting in uneven light around the light-transmitting ring, affecting the user experience. To address this problem, there are currently two ways to improve it: one is to reduce the transparency of the light-transmitting ring to improve the uniformity of the light, but reducing the transparency of the light-transmitting ring will cause the light to be not bright enough. The other is to increase the number of LED lights to improve the uniformity of the light, but this will result in the need to increase the space to place the LED lights, which not only increases the cost, but also limits the size of the knob. Utility Model Content

The light-transmitting ring 32 comprises a main body 321, a light-transmitting part 322 and a light-distributing part 323, wherein the main body 321 is arranged between the housing 10 and the knob 31, the light-transmitting part 322 is connected to a side of the main body 321 close to the knob 31, and is circumferentially sleeved on the outer peripheral side of the knob 31, the light-distributing part 323 is connected to a side of the main body 321 away from the light-transmitting part 322, and the light-distributing part 323 is penetrated through the light-transmitting hole 12 so that the light emitted by the indicator light 21 is emitted through the light-distributing part 323. In this way, the light emitted by the indicator light 21 is diffused by the light homogenizing portion 323 and then transmitted to the main body 321, and finally emitted from the light-transmitting portion 322. The light homogenizing portion 323 is arranged so that the light is homogenized and then emitted from the light-transmitting portion 322, thereby making the light emitted from the light-transmitting ring 32 more uniform. The present application does not need to reduce the light transmittance of the light-transmitting ring 32, does not cause the problem of insufficient light, and does not increase the number of indicator lights 21, so there is no need to increase the cost and adjust the installation position of the indicator light 21 and the size of the knob 31.

[0038] In one embodiment, the light-transmitting ring 32 may be made of translucent engineering plastics, specifically PVC, PC or POM, which is not limited in the present application.

[0039] Furthermore, the housing 10 is provided with a mounting groove 11, the light-transmitting hole 12 is provided on the bottom wall of the mounting groove 11, and the main body 321 is provided in the mounting groove 11.

[0040] Furthermore, the light-transmitting ring 32 further includes a buckle 324 connected to the main body 321, and the bottom wall of the mounting groove 11 is provided with a mounting hole 14, and the buckle 324 is buckled in the mounting hole 14 to connect the light-transmitting ring 32 to the housing 10. In this way, the light-transmitting ring 32 is installed on the housing 10 through the buckle 324, and the structure is simple and easy to install.

[0041] Further, please refer to Figure 2 , Figure 4 and Figure 5 . A positioning structure is provided between the housing 10 and the light-transmitting ring 32. The positioning structure includes a positioning protrusion 13 and a positioning hole 325. One of the positioning protrusion 13 and the positioning hole 325 is provided on the bottom wall of the mounting groove 11, and the other is provided on the main body portion 321. The positioning protrusion 13 passes through the positioning hole 325 to determine the installation position of the light-transmitting ring 32 in the mounting groove 11. In this way, the installation position of the light-transmitting ring 32 can be quickly determined through the cooperation of the positioning protrusion 13 and the positioning hole 325, improving production efficiency and avoiding the non-correspondence between the light homogenizing portion 323 and the indicator light 21. In this embodiment, the positioning protrusion 13 is provided on the bottom wall of the mounting groove 11, and the positioning hole 325 is provided on the main body portion 321. Of course, in other embodiments, it may also be that the positioning protrusion is provided on the main body portion and the positioning hole is provided on the bottom wall of the mounting groove.

The rotary switch is an encoder, and the knob 31 is connected to the rotary switch through a bracket 311, so as to control the opening and closing of the rotary switch by rotating the knob 31. An avoidance hole 326 for the bracket 311 to pass through is provided on the main body portion 321 of the light-transmitting ring 32. In this embodiment, the bracket 311 and the knob 31 are two independent structures, and the two independent structures are fixedly connected. However, it is not limited thereto. In other embodiments, the bracket and the knob may also be an integral structure.

[0043] Please refer to Figure 4 . The orthographic projection of the light homogenizing portion 323 on the circuit board 20 covers the indicator light 21. In this way, it is ensured that the light emitted by the indicator light 21 first passes through the light homogenizing portion 323 for diffusion and homogenization, then passes through the main body portion 321, and finally exits from the light-transmitting portion 322, thereby further ensuring the uniformity of the emitted light. It is worth mentioning that Figure 4 is a partial structural schematic diagram of the cooking appliance outside the housing 10. The solid lines represent the structures exposed outside, and the dotted lines represent the structures hidden inside. This figure aims to present the relative positional relationship between the indicator light 21 and the light homogenizing portion 323. Therefore, the indicator light 21 and the light homogenizing portion 323 are schematically shown by dotted lines in the figure, and other structures hidden inside the housing 10 are not shown.

[0044] Further, the side wall of the light homogenizing portion 323 is provided with texture, so that the light emitted by the light homogenizing portion 323 is more uniform.

[0045] Further, please refer to Figure 2 and Figure 5, the direction in which the light homogenizing part 323 extends from the main body part 321 towards the indicator light 21 is defined as the height direction of the light homogenizing part 323, and the height of the light homogenizing part 323 is 2.5 mm to 3 mm. If the height of the light homogenizing part 323 is too small, the light homogenizing effect is not obvious. If the height of the light homogenizing part is too large, it will cause the volume of the light transmitting aperture 32 to be relatively large, thus affecting the installation of the light transmitting aperture 32. In this embodiment, the height of the light homogenizing part 323 is 2.5 mm to 3 mm, and the height of the light homogenizing part 323 is appropriate, which can not only ensure the light homogenizing effect, but also not affect the installation due to the too large volume of the light transmitting aperture 32. Specifically, the height of the light homogenizing part 323 can be 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, 3 mm, or any other arbitrary value within the range of 2.5 mm to 3 mm.

[0046] Please refer to Figure 6 , the indicator lights 21 are arranged in multiple numbers, and the multiple indicator lights 21 are distributed in a ring shape. Please refer to Figure 5 , the light homogenizing parts 323 are arranged in multiple numbers, and the multiple light homogenizing parts 323 are distributed in a ring shape. In this way, the light homogenizing parts 323 and the indicator lights 21 are correspondingly arranged, and a ring-shaped light emitting area can be formed, so that the entire circle of the light transmitting part 322 can be illuminated, having a better indication and decorative effect.

[0047] In this embodiment, the indicator light 21 is an LED lamp, specifically an LED surface mount lamp bead.

[0048] Further, please refer to Figures 4 to 6 , the orthographic projection of each light homogenizing part 323 on the circuit board 20 covers at least two indicator lights 21, and the indicator lights 21 covered by each light homogenizing part 323 can emit at least two different colors of light. In this way, the light transmitting part 322 can have at least two different colors of light displays, and the lights of different colors can indicate different states of the knob 31, thereby improving the light interaction of the cooking appliance. For example, the red light indicates that the knob 31 is in the off state, and the white light indicates that the knob 31 is in the on state. In this embodiment, the orthographic projection of each light homogenizing part 323 on the circuit board 20 covers two indicator lights 21, one of the indicator lights 21 can emit red light, and the other indicator light 21 can emit white light. Of course, in other embodiments, the indicator lights 21 can also emit other different colors of light.

[0049] In this embodiment, the light homogenizing part 323 is fan-shaped, and the structure is very simple.
