Description
Technical Field
[0001] This utility model relates to the field of grills, and in particular to a grill knob assembly. Background Technology
[0002] A grill is a kitchen appliance used for grilling food. Electric grills use electricity as their energy source, converting electrical energy into heat energy to grill food. Using electricity as an energy source for grilling food is clean, safe, convenient, and fast, making it a popular kitchen appliance for improving quality of life.
[0003] The knob mechanism is a component on the grill, which can be used to select different grilling levels to achieve different grilling methods. As people continue to pursue a higher quality of life, the functions of kitchen appliances are constantly being updated. The function of the grill has also evolved from the traditional single grilling function to multi-level grilling. How to simply and accurately display the working status of various grills is a problem that the knob assembly urgently needs to solve. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model is proposed.
[0005] The technical solution of this utility model is implemented as follows: a grill knob assembly includes: a mounting base with a mounting hole; a panel fixed to the back of the mounting base, a rotary encoder switch disposed on the panel, at least one LED bead disposed around the rotary encoder switch, the rotary encoder switch being located at the center of the mounting hole, and the LED bead being located inside the mounting hole; a light-transmitting cover rotatably disposed in the mounting hole, a press button disposed in the center of the light-transmitting cover, and a spring disposed between the press button and the light-transmitting cover, so that the press button can remain in its original position. By pressing the press button, the press button can slide, thereby compressing the spring and triggering the rotary encoder switch.
[0006] In one embodiment, the grill knob assembly further includes a light shield that covers the light-transmitting cover, such that only the annular portion of the top of the light-transmitting cover is exposed.
[0007] In one embodiment, at least one first limiting groove is provided on the outer side of the light-transmitting cover, and a first limiting protrusion is provided on the inner side of the light-shielding cover. When the light-shielding cover is placed on the light-transmitting cover, the first limiting protrusion cooperates with the first limiting groove.
[0008] In one embodiment, the top of the rotary encoder switch is provided with a limiting surface, and the pressing key cooperates with the limiting surface so that the pressing key can drive the rotary encoder switch to rotate.
[0009] In one embodiment, the light-transmitting cover has a receiving groove, and the pressing key is embedded in the receiving groove, so that the top of the light-transmitting cover is flush with the top of the pressing key.
[0010] In one embodiment, a second limiting groove is provided in the receiving groove, and a second limiting protrusion is provided on the pressing key. When the pressing key is installed in the receiving groove, the second limiting protrusion cooperates with the second limiting groove, thereby enabling the light-transmitting cover to drive the pressing key to rotate.
[0011] In one embodiment, two locking claws are symmetrically arranged inside the light-transmitting cover, and two locking blocks are correspondingly arranged on both sides of the pressing key. When the pressing key moves into the light-transmitting cover, the locking blocks abut against the locking claws, causing the locking claws to deform until the locking blocks completely pass over the locking claws, thereby locking the pressing key with the light-transmitting cover.
[0012] The advantages of this utility model are:
[0013] (1) By setting up a light-transmitting cover, the different colors of the LED beads indicate the working status of the grill, which is simple and intuitive;
[0014] (2) By setting up a press button and a spring, the start and stop of the grill can be controlled by pressing, so that the button integrates multiple functions;
[0015] (3) By setting the first limiting protrusion, the first limiting groove, the second limiting protrusion, the second limiting groove, and the limiting surface, the knob assembly can rotate synchronously and has a compact structure. By setting the snap-fit block and snap-fit gripper, the knob assembly can be installed and disassembled conveniently. Attached Figure Description

Detailed Implementation
[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0024] like Figures 1 to 6 As shown, this utility model discloses a grill knob assembly, including: a mounting base 1 with a mounting hole 11; a panel 2 fixed to the back of the mounting base 1, a rotary encoder switch 22 provided on the panel 2, at least one LED bead 21 arranged around the rotary encoder switch 22, the rotary encoder switch 22 being located at the center of the mounting hole 11, and the LED bead 21 being located inside the mounting hole 11; a light-transmitting cover 3 rotatably disposed in the mounting hole 11, a pressing button 5 provided in the middle of the light-transmitting cover 3, and a spring 4 provided between the pressing button 5 and the light-transmitting cover 3, so that the pressing button 5 can remain in its original position. By pressing the pressing button 5, the pressing button 5 can slide, thereby compressing the spring 4 and triggering the rotary encoder switch 22.
[0025] In this embodiment, six LED beads are arranged in a ring.
[0026] It is worth mentioning that the LED bead 21 has multiple colors and can display different colors according to the different working states of the grill. The status is displayed by using a light-transmitting cover 3.
[0027] Preferably, the grill knob assembly further includes a light shield 6, which covers the light-transmitting cover 3, such that only the top annular portion of the light-transmitting cover 3 is exposed.
[0028] Understandably, by setting up the light shield 6, the light-emitting area of the knob assembly can be controlled, and the light-transmitting cover 3 can be protected.
[0029] Preferably, at least one first limiting groove 31 is provided on the outer side of the light-transmitting cover 3, and a first limiting protrusion 61 is provided on the inner side of the light-shielding cover 6. When the light-shielding cover 6 is placed on the light-transmitting cover 3, the first limiting protrusion 61 cooperates with the first limiting groove 31.
[0030] It is understandable that rotating the light-blocking cover 6 can drive the light-transmitting cover 3 to rotate.
[0031] Preferably, the rotary encoder switch 22 is provided with a limiting surface 221 on its top, and the pressing key 5 cooperates with the limiting surface 221 so that the pressing key 5 can drive the rotary encoder switch 22 to rotate.
[0032] Preferably, the light-transmitting cover 3 has a receiving groove 32, and the pressing key 5 is embedded in the receiving groove 32, so that the top of the light-transmitting cover 3 is flush with the top of the pressing key 5.
[0033] Preferably, a second limiting groove 321 is provided in the receiving groove 32, and a second limiting protrusion 51 is provided on the pressing key 5. When the pressing key 5 is installed in the receiving groove 32, the second limiting protrusion 51 cooperates with the second limiting groove 321, so that the light-transmitting cover 3 can drive the pressing key 5 to rotate.
[0034] This configuration allows the rotating encoder switch 22 to rotate via the light-transmitting cover 3 and the pressing button 5 when the light-shielding cover 6 is rotated, thereby controlling the grill.
[0035] Preferred, combined Figure 5 and Figure 6 As shown, two locking claws 33 are symmetrically arranged inside the light-transmitting cover 3, and two locking blocks 52 are correspondingly arranged on both sides of the pressing button 5. When the pressing button 5 moves into the light-transmitting cover 3, the locking blocks 52 abut against the locking claws 33, causing the locking claws to deform until the locking blocks 52 completely pass over the locking claws 33, thereby locking the pressing button 5 with the light-transmitting cover 3.
[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
