Description

Technical Field

[0001] This application relates to the field of oven accessories, and in particular to an infrared oven knob with gradient light. Background Technology

[0002] Currently, infrared ovens have been widely used and developed in the market due to their advantages of directly heating the baking pan with medium-wave infrared rays generated by electrifying carbon fibers based on the principle of solar radiation, without producing combustion exhaust gas and carbon dust, and maintaining fresh indoor air.

[0003] Traditionally, adjusting the temperature of infrared ovens has been done by rotating an external knob. This method relies on a dial marking for temperature control; the operator sets the oven temperature by rotating the knob and observing the dial's indication. This is a common method for oven temperature control, adopted by many oven manufacturers, and is relatively simple and inexpensive. However, with prolonged use, the limitations of this method have become increasingly apparent.

[0004] In the existing technology, the temperature can only be indicated by the pointer on the knob and the scale on the oven dial by rotating an external knob. When used in a dimly lit environment, the pointer and the scale on the oven dial are not easy to observe, making it inconvenient to provide feedback on changes in oven temperature. Therefore, there is still room for improvement. Summary of the Invention

[0005] To facilitate feedback on changes in oven temperature adjustment, this application provides an infrared oven knob with gradually changing light.

[0006] The infrared oven knob with gradually changing light provided in this application adopts the following technical solution: An infrared oven knob with gradient light includes a base, a rotating housing rotatably connected to the base, and a circuit board disposed within the base. The surface of the circuit board is provided with a plurality of light-emitting modules for emitting light of different colors. The plurality of light-emitting modules are distributed along the circumferential direction of the rotation axis of the rotating housing. A light-transmitting part is provided on the side of the rotating housing for the light source to pass through. The light-transmitting part rotates synchronously with the rotating housing. As the rotation angle of the rotating housing changes, the light-transmitting part displays light of different colors.

[0007] By adopting the above technical solution, the rotating outer shell can rotate relative to the base, and several light-emitting modules on the surface of the circuit board are distributed circumferentially along the rotation axis of the rotating outer shell. When the rotating outer shell rotates, the light-transmitting part on its side rotates synchronously. As the rotation angle of the rotating outer shell changes, the light-transmitting part can display different colors of light, realizing the function of indicating the current oven temperature setting based on the change of the knob angle. Compared with the traditional oven knob that can only be adjusted by the dial scale and the light color remains unchanged, this avoids the problem of inconvenient adjustment of the oven temperature due to unclear scale. Preferably, the light-emitting modules in each group are, in order, a white light-emitting module, a blue light-emitting module, and a red light-emitting module along the rotation direction of the rotating shell.

[0008] By adopting the above technical solution, different colored light-emitting modules are arranged in a specific order, so that when the rotating shell rotates, the light-transmitting part can display different colored lights in the order of white, blue and red, which more clearly and intuitively indicates the change of oven temperature.

[0009] Preferably, the rotating housing is provided with an independent light-transmitting plate, and the surface of the independent light-transmitting plate is provided with a light-transmitting channel for the light source to pass through. The light inlet of the light-transmitting channel faces the light-emitting module on the surface of the circuit board, and the light outlet of the light-transmitting channel faces the light-transmitting part.

[0010] By adopting the above technical solution, the light source of the light-emitting module can be accurately transmitted to the light-transmitting part through the light-transmitting channel on the independent light-transmitting plate, ensuring the light display effect, and the independent light-transmitting plate helps to realize the independent display of the light source.

[0011] Preferably, the light-emitting module includes a plurality of LEDs, wherein the white light-emitting module has two LEDs, the blue light-emitting module has three LEDs, and the red light-emitting module has two LEDs.

[0012] By adopting the above technical solution and rationally planning the number of LED beads in different color light-emitting modules, a more accurate and stable light gradient effect can be presented, clearly indicating the changes in oven temperature.

[0013] Preferably, a transparent cover plate is provided inside the base, and the transparent cover plate covers the surface of the circuit board.

[0014] By adopting the above technical solution, a transparent cover plate can be used to cover the surface of the circuit board, which can prevent water and dust from contacting the circuit board and also play an insulating role, ensuring the normal operation of the circuit board.

[0015] Preferably, the inner peripheral wall of the rotating outer shell is provided with a protrusion, and the outer peripheral surface of the independent light-transmitting plate is provided with a groove that engages with the protrusion.

[0016] By adopting the above technical solution, the protrusion and the slot can be used to securely install the independent light-transmitting panel inside the rotating housing, preventing the independent light-transmitting panel from loosening or shifting and affecting the light transmission and lighting display effect.

[0017] Preferably, the bottom of the independent light-transmitting plate is provided with an installation part, which extends to the bottom outer side of the base. A spring clip is provided at the installation part to ensure that the installation part and the oven temperature control valve are tightly fitted.

[0018] By adopting the above technical solution, an installation part is set at the bottom of the independent light-transmitting plate and a spring clip is set at the installation part, so that the installation part can be tightly connected with the oven temperature control valve, preventing the independent light-transmitting plate from easily falling off and enhancing the stability of the connection between the oven knob and the temperature control valve.

[0019] Preferably, the base is provided with a mounting hole, the circuit board is provided with a clearance hole aligned with the mounting hole, the transparent cover is provided with a through hole aligned with the clearance hole, and the mounting part passes through the through hole, the clearance hole and the mounting hole in sequence.

[0020] By adopting the above technical solution, it is ensured that the mounting part of the independent light-transmitting plate can smoothly pass through the base, circuit board and transparent cover, so that the spring card can be connected to the oven temperature control valve to achieve a tight fit. At the same time, it facilitates the assembly between the base, circuit board and transparent cover, and ensures the stability and rationality of the overall structure of the knob.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The rotating outer shell causes the light-transmitting part to rotate synchronously. Combined with different colored light-emitting modules distributed along the circumference on the circuit board, the light-transmitting part can display different colored lights, which solves the problem that it is difficult to observe the pointer and scale in a dim scene and thus makes it inconvenient to adjust the temperature. This facilitates feedback on changes in oven temperature adjustment. 2. The independent light-transmitting plate is equipped with light-transmitting channels for light source transmission. It is fixed by snapping with the protrusion on the inner peripheral wall of the rotating housing, which ensures independent light source transmission and facilitates installation. 3. The spring clip ensures a tight fit between the independent light-transmitting plate and the oven temperature control valve, preventing the knob from coming off and ensuring its proper function.

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0027] This application discloses an infrared oven knob with gradually changing light, referring to... Figures 1 to 3 The oven includes a base 2, a rotating outer shell 1, a circuit board 5, an independent light-transmitting plate 3, and a transparent cover 6. The rotating outer shell 1 is rotatably connected to the base 2, and the circuit board 5 is housed within the base 2. This arrangement allows the rotating outer shell 1 to rotate flexibly relative to the base 2, while the circuit board 5 is stably positioned within the base 2 to provide a foundation for subsequent light-emitting functions. A light-transmitting section 11 is provided on the side of the rotating outer shell 1, allowing the light source to pass through. The light-transmitting section 11 rotates synchronously with the rotating outer shell 1. The surface of the circuit board 5 is provided with several light-emitting modules that emit different colors of light. These modules are distributed circumferentially along the rotation axis of the rotating outer shell 1. As the rotation angle of the rotating outer shell 1 changes, the light-transmitting section 11 displays different colors of light. This allows the color of the light to visually reflect changes in the oven temperature, facilitating user operation.

[0028] The light-emitting modules on the upper surface of circuit board 5, along the rotation direction of the rotating housing 1, are sequentially white light-emitting module 52, blue light-emitting module 53, and red light-emitting module 54. Each light-emitting module includes several LED beads; white light-emitting module 52 has two LED beads, blue light-emitting module 53 has three LED beads, and red light-emitting module 54 has two LED beads. LED beads are generally used, offering advantages such as energy saving, high brightness, and long lifespan. Different colored LED beads can be selected according to actual needs, using different models and specifications. OLED or other light-emitting elements can also be used instead of LED beads. Additionally, a connecting plate 56 is located at the lower end of one side of circuit board 5, and a dimming controller 57 is installed at the lower end of the connecting plate 56. The dimming controller 57 precisely controls the brightness of each light-emitting module or each color channel (white, blue, red) by changing the current or voltage supplied to the LED (or OLED) beads, or by using PWM (pulse width modulation) technology to control the conduction time ratio of the LED beads.

[0029] In this embodiment, the light-emitting module in circuit board 5 uses infrared sensing to turn the light on and off. An infrared sensor switch 55 is installed on one side of circuit board 5. When the light-transmitting part 11 of the rotating housing 1 is in the OFF position on the base 2 or oven dial, the infrared emitting tube of circuit board 5 emits infrared light, which is reflected back to the infrared receiving window of circuit board 5 by the reflector inside the rotating housing 1. This triggers the infrared sensor switch 55 circuit to shut off the LED lamp bead circuit current, thus turning off the lamp bead. When rotating housing 1 so that the reflector moves away from the infrared emitting tube, the infrared receiving window does not receive the infrared signal reflected back by the reflector. The switch circuit closes the LED lamp bead circuit, providing operating current to the LED lamp bead, and the lamp bead turns on. Circuit board 5 is equipped with LED lamp beads of different colors. As the angle of the rotating housing 1 changes, the light-transmitting window displays different colors to indicate changes in the currently set oven temperature. The infrared sensor switch 55 is a non-contact switch, greatly extending the product's lifespan. The circuit operates at DC 5V, with a lighting current below 20mA and a standby current in the microamp level. It has low standby power consumption, making it energy-saving, environmentally friendly, and safe.

[0030] Specifically, the rotating outer shell 1 is a key component for manually adjusting the oven temperature. It is generally made of materials such as plastic, possessing a certain degree of strength and durability. The inner circumferential wall of the rotating outer shell 1 has several protrusions 12, which can be elongated strips, evenly distributed along the circumference of the inner circumference of the rotating outer shell 1. These protrusions 12 can also be replaced by similar structures such as locking blocks. Four mounting pillars 13 are vertically arranged on the top inner wall of the rotating outer shell 1.

[0031] An independent light-transmitting plate 3 is disposed inside the rotating housing 1, and the upper surface of the independent light-transmitting plate 3 abuts against the lower end face of the mounting column 13 to maintain horizontality. The independent light-transmitting plate 3 is typically made of plastic material, and its surface is provided with a light-transmitting channel 31 through which a light source can pass. The upper and lower parts of the light-transmitting channel are respectively disposed on the upper and lower surfaces of the independent light-transmitting plate 3. The lower part of the light-transmitting channel 31 is provided with a light inlet facing the light-emitting module on the surface of the circuit board 5. The upper part of the light-transmitting channel 31 is provided with a light outlet facing the light-transmitting part 11. The light-transmitting part 11 is specifically an LED lens used for light display. In this embodiment, the light-transmitting channel 31 can be circular, square, or other shapes to precisely guide the light. The outer peripheral surface of the independent light-transmitting plate 3 is provided with a groove 34 that engages with the protrusion 12 on the inner peripheral wall of the rotating housing 1. The shape and size of the groove 34 are adapted to the protrusion 12 to ensure a tight engagement. The groove 34 can also be replaced by a recess or similar structure. Through the snap-fitting of the protrusion 12 and the slot 34, the independent light-transmitting plate 3 can be stably installed inside the rotating housing 1, achieving synchronous rotation of the two.

[0032] It should be emphasized that, in order to improve the gradient effect of the light, the structural dimensions of the light-transmitting channel can be designed so that the width of the light inlet at the lower part of the light-transmitting channel 31 is greater than the distance between adjacent LED beads. This allows the light inlet at the lower part of the light-transmitting channel 31 to cover two LED beads when the light-transmitting channel rotates with the rotating housing 1, so that the light from the two LED beads of different colors can be mixed and presented, further improving the gradient effect of the light.

[0033] In this embodiment, the base 2 is the supporting component for the entire knob, typically made of materials such as plastic or metal, possessing a certain degree of strength and stability. A transparent cover 6 is installed inside the base 2 and covers the surface of the circuit board 5. The transparent cover 6 is generally made of transparent plastic, allowing light to pass through while also protecting the circuit board 5. The transparent cover 6 can be fixed inside the base 2 using clips, glue, or other methods. Alternatively, the transparent cover 6 can be made of transparent materials such as glass.

[0034] The base 2 has a mounting hole 21 in the middle, the circuit board 5 has a clearance hole 51 aligned with the mounting hole 21 in the middle, the transparent cover 6 has a through hole 61 aligned with the clearance hole 51 in the middle, and the independent light-transmitting plate 3 has a mounting part 32 at its bottom. The mounting part 32 is cylindrical, and the end of the mounting part 32 away from the light-transmitting plate passes through the through hole 61, the clearance hole 51, and the mounting hole 21 in sequence. This arrangement allows the mounting part 32 to pass through each component and finally connect to the oven temperature control valve. The shapes and sizes of the mounting hole 21, the clearance hole 51, and the through hole 61 are matched to ensure that the mounting part 32 can pass through smoothly.

[0035] The mounting part 32, located away from the light-transmitting plate, has a recessed mounting groove 33, within which a spring clip 4 is installed. The spring clip 4 is typically made of a metal spring sheet and possesses good elasticity. Its function is to ensure a tight fit between the mounting part 32 and the oven temperature control valve, preventing it from easily coming loose. The spring clip 4 can be ring-shaped, C-shaped, or similar, using its own elastic deformation to tightly hold the mounting part 32, enhancing the stability of the connection with the oven temperature control valve. Alternatively, the spring clip 4 can be replaced with a rubber ring or other elastic component.

[0036] The implementation principle of this embodiment is as follows: The infrared oven knob with gradually changing light in this embodiment achieves the function of changing light with the rotation angle through the ingenious combination of components such as the rotating outer shell 1, the independent light-transmitting plate 3, the spring clip 4, the base 2, the transparent cover 6, and the circuit board 5. When the outer shell 1 is rotated, the independent light-transmitting plate 3 rotates synchronously, and the light-transmitting channel 31 will sequentially align with the light-emitting modules of different colors, thereby making the light-transmitting part 11 display different colored lights, intuitively reflecting the changes in oven temperature. Compared with traditional knobs, it avoids the problem of difficulty in adjusting the temperature due to ambiguous scales, improving the convenience and accuracy of use. At the same time, the non-contact switch design greatly extends the product's service life, and the low power consumption feature is also more energy-efficient, environmentally friendly, and safe.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
