[0032] This utility model proposes a lighting structure 400 and a kitchen appliance, see reference. Figures 1-5 The kitchen appliance includes a body 100, a door assembly 200, and a lighting structure 400.

[0033] The machine body 100 has a working cavity for placing food to be heated.

[0034] A food inlet port is formed on the front side of the body 100, and a door assembly 200 is disposed on the body 100 to realize the opening and closing of the food inlet port.

[0035] A lighting structure 400 is mounted on the body 100. The lighting structure 400 includes a light source 420 for emitting a light beam. A reflector 210 is formed on the door assembly 200. The reflector 210 is positioned opposite to the light source 420 and is used to reflect the light beam formed by the light source 420 to the outside of the body 100.

[0036] A panel assembly 300 is provided on the front side of the body 100. The panel assembly 300 is located above the food inlet port, that is, above the door assembly 200. A light-transmitting opening 331 extending along the length of the body 100 is provided below the panel assembly 300. The light structure 400 is installed inside the panel assembly 300.

[0037] Correspondingly, the reflector 210 is set on the top of the door assembly 200, opposite to the light-transmitting opening 331.

[0038] In this application, a reflector 210 is provided on the door assembly 200 at a position opposite to the light source 420 on the lighting structure 400. The light beam formed by the light source 420 shines on the reflector 210 and is reflected by the reflector 210 to the outside of the body 100. The light beam is more obvious and has stronger visibility, making it convenient for users to observe from all directions. In some embodiments of this application, the light source 420 is an LED light strip extending along the length of the body 100.

[0039] The light source 420 is an LED light strip. The light-transmitting opening 331 and the reflector 210 are both long strips corresponding to the length of the light source 420. The controller switches the light source 420 to different colors or states according to the different working states of the kitchen appliances, which serves as a reminder to the user.

[0040] The long strip of light formed by the light source 420 is emitted through the light-transmitting port 331 onto the reflector, and then reflected by the reflector to the outside of the machine body 100. The lighting effect is stronger, the aesthetics are better, and the warning effect is better, which makes it easier for users to observe the working status of the kitchen appliance from all directions.

[0041] refer to Figure 6 In some embodiments of this application, the lighting structure 400 is installed inside the panel assembly 300. The panel assembly 300 includes a control panel 310 and an inner mounting plate 320 spaced apart. A mounting cavity is formed between the control panel 310 and the inner mounting plate 320. The lighting structure 400 is disposed in the mounting cavity.

[0042] The bottom of the installation chamber is provided with a support base plate 330, the lighting structure 400 is specifically fixed on the support base plate 330, and the light-transmitting opening 331 is formed on the support base plate 330.

[0043] The control panel 310, the support base plate 330, and the inner mounting plate 320 provide a mounting base for the lighting structure 400. The lighting structure 400 is set in the mounting chamber to avoid contact with the working inner cavity of the body 100, thus ensuring higher safety.

[0044] In some embodiments of this application, the lower part of the door assembly 200 is hinged to the body 100 via a rotating part, and the door assembly 200 is configured to flip down and open along the rotating part.

[0045] refer to Figure 7 The reflector 210 is set on the top of the door assembly 200, and the light beam is emitted from between the door assembly 200 and the panel assembly 300, making the position of the light easier to observe and easier to maintain later.

[0046] In some embodiments of this application, the door assembly 200 includes an outer door panel 220 and an inner door shell 230. The inner door shell 230 is a shell structure. An installation gap 240 is formed between the outer door panel 220 and the inner door shell 230, and a reflector 210 is installed in the installation gap 240.

[0047] Reference 8. Figure 9 The reflector 210 includes a connecting vertical part 211, a horizontal connecting part 212, and an inclined reflector 213. The connecting vertical part 211 is inserted into the installation gap 240, the horizontal connecting part 212 is located on the top of the door shell, and the inclined reflector 213 extends obliquely downward in the direction away from the horizontal connecting part 212.

[0048] The connecting upright 211 is used to connect the reflector to the door assembly 200. The horizontal connecting part 212 limits the connection position of the connecting upright 211. The light beam generated by the light source 420 is emitted onto the inclined reflector 213 and reflected to the outside of the body 100.

[0049] In some embodiments of this application, a controller is also included. The controller is installed inside the body 100 and is connected to the light source 420. The controller is used to control the light source 420 to switch the light beam of different colors or different states for different working states.

[0050] The controller controls the light source 420 to form different colors for different working states of kitchen appliances, such as preheating, heating, completion, and malfunction.

[0051] For example, but not limited to: during preheating, the controller controls the light source 420 to form a yellow beam; during heating, it forms a white beam; upon completion, it forms a blue beam; and in case of a malfunction, it forms a red beam.

[0052] In other embodiments, along with different color effects, the controller also controls the light source 420 to form different lighting effects for different operating states.

[0053] For example, but not limited to: during preheating and heating, the light source 420 forms a progress bar-like lighting effect according to the preset time. Since the light source 420 is long and narrow, the progress bar of the light gradually increases as the preheating or working time progresses. When completed, the light source 420 forms a breathing light-like lighting effect.

[0054] The aforementioned effects of light source 420 are beneficial to improving the aesthetics of kitchen appliances and to product optimization and upgrading.

[0055] refer to Figure 8 In some embodiments of this application, the outer door panel 220 is also provided with a handle portion 250, which includes a handle horizontal portion 251 and a handle vertical portion 252. The handle horizontal portion 251 is arranged perpendicularly to the outer door panel 220, and the handle vertical portion 252 is perpendicular to the handle horizontal portion 251 and extends downward.

[0056] The handle 250 is designed for easy hand gripping, allowing the door panel assembly to be flipped downwards to open.

[0057] A support block 253 is also provided on the outer wall of the outer door panel 220. The support block 253 is located at both ends of the handle part 250 to provide support for the handle part 250. The handle horizontal part 251 and the handle vertical part 252 are connected to the support block 253 so that an operating space is formed between the handle horizontal part 251 and the outer door panel.

[0058] When the user opens or closes the door assembly 200, the user holds the horizontal part of the handle 251 for easy opening and closing.

[0059] refer to Figures 10-12 In some embodiments of this application, the lighting structure 400 further includes a housing 410 and a diffuser 430. The housing 410 is an elongated shell structure and is fixed in the mounting cavity.

[0060] The light source 420 is installed inside the housing 410 along the length of the housing 410, as detailed in the reference. Figure 10 An opening 414 is formed at the bottom of the outer casing 410. The opening 414 is connected to the light-transmitting port 331. The light beam generated by the light source 420 is emitted from the light-transmitting port 331 through the opening 414.

[0061] The diffuser 430 is disposed inside the housing 410, specifically between the light source 420 and the opening 414.

[0062] In some embodiments of this application, a non-linear spatial channel is formed inside the outer shell 410, and the spatial channel is arc-shaped along the tangential direction perpendicular to the length of the outer shell 410.

[0063] A reflective layer is formed on the side wall of the space channel, the light source 420 is set at the top of the space channel, and the opening 414 is formed at the bottom of the space channel.

[0064] The diffuser 430 is disposed within the space channel, located between the light source 420 and the opening 414.

[0065] The diffuser 430 is used to improve the continuity and softness of the beam, resulting in better output light.

[0066] In addition, depending on the actual usage requirements, the particle density inside the diffuser 430 can be specifically changed during the design process, thereby changing the light transmission effect of the diffuser 430 and the intensity of the output beam.

[0067] In addition, the diffuser 430 is specifically a diffuser plate structure with a smooth surface on one side and a concave-convex surface on the other side. By changing the degree of concavity and convexity of the diffuser plate, the wavelength of light absorbed by the diffuser 430 can be adjusted, thereby adjusting the color of the light.

[0068] The aforementioned characteristics of the diffuser plate in altering the intensity and color of the light beam are existing technologies. The specific methods of alteration are not the focus of this application and will not be described in detail here.

[0069] In some embodiments of this application, in conjunction with the light source 420, the opening 414 is an elongated opening structure located at the bottom of the outer casing 410, and a partition 440 is installed inside the opening 414. The partition 440 is made of transparent material.

[0070] The partition 440 is used to isolate the space passage from the outside world, preventing moisture, dust and other contaminants from entering the space passage and improving safety.

[0071] In some embodiments of this application, the diffuser 430 and the light source 420 are arranged at an angle, and the diffuser 430 and the barrier 440 are arranged at an angle.

[0072] The angled arrangement of the light source 420, the diffuser 430, and the baffle 440 helps to prevent the light beam generated by the light source 420 from shining directly out of the opening 414. The light beam is refracted by the reflective layer and scattered by the diffuser 430, making the light softer and more continuous.

[0073] In some embodiments of this application, a sealing strip 450 is also provided on the periphery of the partition 440, and the sealing strip 450 is connected between the opening 414 and the partition 440.

[0074] The sealing strip 450 is specifically connected to the periphery of the partition 440 and to the opening 414. The sealing strip 450 is used to seal the installation gap 240 between the partition 440 and the opening 414 to improve the sealing effect.

[0075] Specifically, the sealing strip 450 is a foam tape. After the partition 440 is installed, the sealing strip 450 is pasted on the outer periphery of the partition 440 and the opening 414.

[0076] refer to Figure 13 In some embodiments of this application, a first mounting groove 4101, a second mounting groove 4102 and a third mounting groove 4103 are formed inside the outer casing 410. The light source 420 is installed in the first mounting groove 4101, the diffuser 430 is disposed in the second mounting groove 4102, and the baffle 440 is disposed in the third mounting groove 4103.

[0077] refer to Figures 14-17 In some embodiments of this application, the outer shell 410 is an injection molded part, and the outer shell 410 includes a first shell 411 and a second shell 412. An intermediate connecting portion 413 is formed between the first shell 411 and the second shell 412, and an opening 414 is formed between the first shell 411 and the second shell 412.

[0078] The first housing 411 and the second housing 412 can be unfolded or closed with the intermediate connecting part 413 as the connection center.

[0079] The light source 420, the diffuser 430, and the partition 440 are clamped between the first housing 411 and the second housing 412, which makes it easier to connect and fix the light source 420, the diffuser 430, and the partition 440, reduces the assembly difficulty, and helps to improve the assembly efficiency.

[0080] In some embodiments of this application, the first housing 411 has snap-fit ​​portions 4111 at both ends, and the second housing 412 has snap-fit ​​portions 4121 at both ends, and the snap-fit ​​portions 4111 and the corresponding snap-fit ​​portions 4121 are detachably connected.

[0081] Alternatively, the first housing 411 and the second housing 412 may also be provided with connecting holes at both ends, and fasteners such as bolts may pass through the connecting holes on the first housing 411 and the second housing 412 to achieve the connection and fixation of the first housing 411 and the second housing 412.

[0082] The first housing 411 and the second housing 412 are snapped together for easy fixing and later disassembly, allowing for maintenance of the internal light source 420 and the diffuser 430.

[0083] The first mounting groove 4101, the second mounting groove 4102, and the third mounting groove 4103 are specifically formed by protrusions in the first housing 411 and the second housing 412. Specifically, three first limiting protrusions are provided at intervals on the inner side of the first housing 411 along the direction away from the intermediate connecting part 413. The connecting protrusions extend along the length direction of the outer housing 410 and are integrally formed with the first housing 411.

[0084] The inner side of the second housing 412 is provided with three second limiting protrusions that correspond one-to-one with the positions of the first limiting protrusions along the distance from the intermediate connecting part 413.

[0085] The first mounting groove 4101, the second mounting groove 4102, and the third mounting groove 4103 are formed by the first limiting protrusion and the second limiting protrusion at corresponding positions.

[0086] During installation, first position the light source 420 and the diffuser 430 to their corresponding positions, then close the first housing 411 and the second housing 412. The light source 420 and the diffuser 430 will then be clamped into the housing 410, making installation quick and convenient.

[0087] The partition 440 is installed in the third mounting groove 4103 from the opening 414, and then the sealing strip 450 is adhered to the periphery of the partition 440 to seal and fix the partition 440.

[0088] In some embodiments of this application, fixing portions 4122 are formed at both ends of the first housing 411 or the second housing 412. Fixing holes are formed on the fixing portions 4122. The fixing portions 4122 are used to be detachably connected to the body 100 of the kitchen appliance. Specifically, the outer housing 410 is connected to the support base plate 330 through the fixing portions 4122.

[0089] The outer casing 410 of the light structure has a non-linear spatial channel, and a reflective layer is formed on the side wall of the spatial channel to reduce beam consumption. The light source 420 is set at one end of the spatial channel, and an opening 414 is formed at the other end. A diffuser 430 is also set in the spatial channel. The beam of light generated by the light source 420 is output from the opening 414 after passing through the diffuser 430. The diffuser 430 is used to improve the continuity and softness of the beam, so that the output light effect is better.

[0090] In addition, the parameters of the diffuser 430 on different kitchen appliances can be adjusted according to the user's needs, thereby adjusting the color and brightness of the light beam output by the diffuser 430 to meet different usage requirements.
