Technical Field
[0001] This utility model relates to the field of smoke alarm technology, and in particular to a refrigerator display module with smoke alarm function. Background Technology
[0002] Fire alarms, also known as smoke detectors, are essential devices for preventing home fires. Their main function is to trigger an alarm when a large amount of smoke is detected, thus alerting people to take measures to prevent the fire from starting or spreading. The sensitivity of fire alarms is typically adjusted based on geographical location and application environment to ensure effective detection in the early stages of a fire.
[0003] Currently, some household refrigerators have a display panel on their surface, which is used to display functions such as temperature, air purification, energy saving, quick freezing, on / off switch, and child lock. Since refrigerators are generally placed in the kitchen, which is a place where open flames are frequently used, some users will install smoke detectors in the kitchen to detect the smoke situation. In this case, the smoke detector is installed independently of the refrigerator and inside the kitchen, which can easily affect the overall aesthetics of the kitchen and cannot meet the pursuit of "minimalism" by some users.
[0004] Therefore, the purpose of this application is to solve how to integrate a smoke sensor with a refrigerator display screen so that it can realize its own touch function while also meeting the application of a smoke sensor. To this end, a refrigerator display screen module with smoke alarm function is proposed. Utility Model Content
[0005] Based on this, it is necessary to provide a refrigerator display module with smoke alarm function to address the above-mentioned technical problems. The backlight frame of the conventional display module is extended to form a frame protrusion, and a groove is dug in the protrusion to form a smoke light sensing hole. The photoelectric smoke sensing module is assembled in the smoke light sensing hole to realize smoke alarm.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] A refrigerator display module with smoke alarm function includes a backlight frame, a cover plate is fixed to the backlight frame with VHB adhesive, the surface of the cover plate has smoke light sensing holes, a frame protrusion extends from the surface of the backlight frame at the position corresponding to the smoke light sensing holes, a light sensing cavity is provided in the frame protrusion, and a photoelectric smoke sensing module is assembled on the frame protrusion through the light sensing cavity.
[0008] The photoelectric smoke sensing module is connected to a photoelectric smoke sensing module FPC for connection with the display screen FPC.
[0009] Furthermore, the smoke light-sensing hole is located outside the visible area of the cover plate.
[0010] Furthermore, the photoelectric smoke sensing module includes a photoelectric smoke sensor body disposed within the photosensitive cavity, and the photoelectric smoke sensing module FPC is attached to the back of the adhesive frame boss and connected to the photoelectric smoke sensor body by strong double-sided adhesive.
[0011] Furthermore, one end of the photoelectric smoke sensing module FPC has a connection end, and the photoelectric smoke sensing module FPC is connected to the display screen FPC through the connection end.
[0012] Furthermore, the photoelectric smoke sensing module also includes a steel sheet reinforcement, which is disposed on the back of the photoelectric smoke sensing module FPC and at a position corresponding to the photoelectric smoke sensor body.
[0013] Furthermore, the backlight frame has an FOG glass module and a backlight module on both sides, and the end of the display FPC away from the connection end is bound to the bottom of the FOG glass module.
[0014] Furthermore, a backlight rear iron frame is fastened to the back of the backlight frame, and the connecting end of the display screen FPC is bent and tightly attached to the back of the backlight rear iron frame.
[0015] Furthermore, a gap is left between the outer periphery of the photoelectric smoke sensor body and the sidewall of the photosensitive cavity.
[0016] Furthermore, the photoelectric smoke sensing system circuit and the buzzer system circuit in the photoelectric smoke sensing module are both set on the display screen FPC. The photoelectric smoke sensing module can be connected to the photoelectric smoke sensing and buzzer system circuits by the action of the photoelectric smoke sensing module FPC.
[0017] Furthermore, the backlight FPC of the backlight module is also bonded to the display FPC;
[0018] The surface of the display FPC is covered with EMI protective paper to protect the backlight FPC, the photoelectric smoke sensing system circuit, and the buzzer system circuit.
[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] The refrigerator display module with smoke alarm function provided by this utility model features a frame protrusion design on the backlight frame of the display module in a conventional refrigerator. This allows the photoelectric smoke sensor module to be mounted on the protrusion through a photosensitive cavity and connected to the display screen FPC via the photosensitive smoke sensor module FPC. This enables the display screen to perform its display function while simultaneously triggering a smoke alarm through the smoke photosensitive hole on the cover plate. This eliminates the need for additional smoke alarm installation in the kitchen space, making it more practical. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0035] As described in the background section, some users install smoke detectors in the kitchen to detect smoke. In this case, the smoke detector is installed outside the refrigerator and inside the kitchen, which can affect the overall aesthetics of the kitchen and cannot meet the "minimalist" pursuit of some users.
[0036] To solve this technical problem, this utility model provides a refrigerator display module with smoke alarm function, which is used for smoke alarm.
[0037] For details, please refer to Figures 1-6 As shown, the refrigerator display module with smoke alarm function specifically includes a backlight frame 1, a cover plate 2 is fixed to the backlight frame 1 by VHB adhesive, the surface of the cover plate 2 has a smoke light sensing hole 21, a frame protrusion 11 extends from the surface of the backlight frame 1 at the position corresponding to the smoke light sensing hole 21, a light sensing cavity 12 is provided in the frame protrusion 11, and a photoelectric smoke sensing module 3 is assembled on the frame protrusion 11 through the light sensing cavity 12;
[0038] The photoelectric smoke sensing module 3 is connected to a photoelectric smoke sensing module FPC35 for connection with the display screen FPC4.
[0039] The refrigerator display module with smoke alarm function provided by this utility model has a frame protrusion 11 on the backlight frame 1 in the display module of a conventional refrigerator. The photoelectric smoke sensor module 3 is mounted on it through the photosensitive cavity 12 and connected to the display screen FPC4 through the photosensitive smoke sensor module FPC35. While realizing the display function, it can also realize the smoke alarm of the outside world through the smoke photosensitive hole 21 on the cover plate 2. Therefore, there is no need to install an additional smoke alarm in the kitchen space, which makes it more practical.
[0040] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0041] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0042] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0043] Example 1
[0044] Please refer to Figures 1-3 As shown, a refrigerator display module with smoke alarm function includes a backlight frame 1. The backlight frame 1 is fixed with a cover plate 2 by VHB adhesive. The surface of the cover plate 2 has a smoke light sensing hole 21. The surface of the backlight frame 1 has a frame protrusion 11 extending from the position corresponding to the smoke light sensing hole 21. A light sensing cavity 12 is provided in the frame protrusion 11. A photoelectric smoke sensing module 3 is assembled on the frame protrusion 11 through the light sensing cavity 12.
[0045] Among them, the photoelectric smoke sensing module 3 is connected to the photoelectric smoke sensing module FPC35 for connection with the display screen FPC4;
[0046] In this embodiment, the conventional photoelectric smoke sensing module 3 is integrated on the surface of the cover plate 2, so that it works together with the display module on the refrigerator. This satisfies the display operation of refrigerator control, and since refrigerators are mostly installed in the kitchen, the photoelectric smoke sensing module 3 set on the display can also realize photoelectric detection of smoke in the kitchen in real time. The integration is better, and there is no need to install a separate smoke sensor on the kitchen wall, making the kitchen more beautiful and simple.
[0047] As a further optimization of this embodiment: the smoke light sensor 21 is located outside the visible area 13 of the cover plate 2;
[0048] like Figure 1 As shown, in this embodiment, the position of the photoelectric smoke sensing module 3 is set outside the visible area of the cover plate 2, so as not to affect the display of the cover plate 2 itself.
[0049] Example 2
[0050] The refrigerator display module with smoke alarm function provided in Embodiment 1 has been further optimized, specifically, as follows: Figure 4 As shown, the photoelectric smoke sensing module 3 includes a photoelectric smoke sensor body 31 disposed in the photosensitive cavity 12, and the photoelectric smoke sensing module FPC35 is attached to the back of the adhesive frame boss 11 by strong adhesive double-sided adhesive 32 and connected to the photoelectric smoke sensor body 31.
[0051] By extending the frame 1 in the conventional backlight to form the frame boss 11, the frame 1 and the frame boss 11 in the backlight are integrated, thus providing a stable mounting foundation for the photoelectric smoke sensing module 3.
[0052] One end of the photoelectric smoke sensing module FPC35 has a connection terminal 33. The photoelectric smoke sensing module FPC35 is connected to the display screen FPC4 through the connection terminal 33. After the photoelectric smoke sensing module 3 is installed on the plastic frame boss 11, the connection terminal 33 of the photoelectric smoke sensing module FPC35 is connected to the display screen FPC4. In this way, when the display screen FPC4 is connected to the main control board of the external refrigerator, the connection of the photoelectric smoke sensing module FPC35 can be realized synchronously without the need for additional wiring connection.
[0053] The photoelectric smoke sensing module 3 also includes a steel sheet reinforcement 34, which is located on the back of the photoelectric smoke sensing module FPC35 and at a position corresponding to the photoelectric smoke sensor body 31.
[0054] The steel reinforcement 34 provides local support for the photoelectric smoke sensing module FPC35, ensuring effective strength support for the installation area of the photoelectric smoke sensing module 3 and preventing excessive bending that could affect the use of the photoelectric smoke sensor body 31 after installation.
[0055] Example 3
[0056] The refrigerator display module with smoke alarm function provided in Embodiment 1 or 2 is further optimized, such as... Figure 3 As shown, FOG glass modules 5 and backlight modules 6 are respectively provided on both sides of the backlight frame 1, and the end of the display screen FPC4 away from the connection end 33 is bound to the bottom of the FOG glass module 5.
[0057] The back of the backlight frame 1 is fastened with a backlight rear iron frame 14, and the connecting end 33 of the display screen FPC4 is bent and tightly attached to the back of the backlight rear iron frame 14.
[0058] There are gaps between the outer periphery of the photoelectric smoke sensor body 31 and the side wall of the photosensitive cavity 12. By setting the gaps, the photoelectric smoke sensor body 31 can avoid collision with the side wall of the photosensitive cavity 12 during use, which is beneficial to the protection of the photoelectric smoke sensor body 31 itself.
[0059] Example 4
[0060] The refrigerator display module with smoke alarm function provided in Embodiment 3 has been further optimized, such as... Figure 4As shown, the photoelectric smoke sensing system circuit and the buzzer system circuit in the photoelectric smoke sensing module 3 are both set on the display screen FPC4. Under the action of the photoelectric smoke sensing module FPC35, the photoelectric smoke sensing module 3 can be connected with the photoelectric smoke sensing and buzzer system circuits. The above-mentioned photoelectric smoke sensing system circuit and buzzer system circuit are technical means well known to those skilled in the art, so this embodiment does not need to be further described.
[0061] After the photoelectric smoke sensor module 3 is connected to the photoelectric smoke sensing system circuit and the buzzer system circuit, it can be connected to the photoelectric smoke sensor module 3 on the cover plate 2 through the connection of the external main control board and the display screen FPC4. In this way, when the photoelectric smoke sensor module 3 detects smoke in the environment through the smoke light sensor 21, it can feed back to the photoelectric smoke sensing system circuit and the buzzer system circuit through the photoelectric smoke sensor FPC35 to realize the smoke alarm.
[0062] As a further optimization of this embodiment: the backlight FPC61 of the backlight module 6 is also bound to the display screen FPC4. The surface of the display screen FPC4 is covered with EMI protective paper 41 to cover and protect the backlight FPC61, the photoelectric smoke sensing system circuit and the buzzer system circuit. The EMI protective paper 41 can cover and protect multiple interface terminals on the display screen FPC4, thus ensuring the stability of the connection between multiple interfaces and reducing external interference.
