Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a bedside refrigerator. Background Technology

[0002] For patients who need to take medication regularly, such as elderly people with heart disease, timely access to their medications is crucial. To meet this need, it's common practice to store medications in easily accessible locations, such as bedside tables. However, some medications are temperature-sensitive and require storage at low temperatures to maintain their effectiveness. While traditional refrigerators can provide the necessary low temperatures, they are bulky and unsuitable for placement in bedrooms or beside beds, making it inconvenient to quickly access medications at night or in emergencies.

[0003] To address this issue, some small refrigeration devices have emerged on the market. While these devices are smaller than traditional refrigerators, they still have certain limitations. For example, most small refrigeration devices use compressors to achieve their cooling function, which generates noticeable noise, potentially disturbing patients who require high-quality sleep.

[0004] In order to solve the above-mentioned technical problems, this utility model designs a bedside refrigerator. Utility Model Content

[0005] This utility model provides a bedside refrigerator cabinet, aiming to solve the noise interference problem caused by the use of compressors in traditional small refrigeration equipment. The technical solution is as follows:

[0006] A bedside refrigerator includes a refrigerator body and legs. The legs are fixed to the bottom of the refrigerator body. The refrigerator body includes a cabinet and a top cover that cooperates with the cabinet. The cabinet includes a storage box and an outer shell. A semiconductor cooler is disposed on the outer shell. The semiconductor cooler is connected to the storage box through a cooling block. A circuit board is also disposed on the outer shell.

[0007] Based on the above technical solution, the end of the semiconductor cooler away from the cooling block is connected to a heat sink and a fan.

[0008] Based on the above technical solution, the top cover is hinged to the top of the box.

[0009] Furthermore, the top cover is provided with a transparent panel.

[0010] Preferably, the space between the placement box and the outer shell is filled with insulating material.

[0011] Beneficial effects

[0012] Compared with existing technologies, the advantages of this invention are as follows: Firstly, it achieves silent operation by using a semiconductor cooler instead of the traditional compressor cooling method, resulting in noiseless operation. This is particularly important for use in bedrooms where a quiet environment is required, especially for patients who have high requirements for sleep quality, as it avoids interference caused by device noise. Secondly, the device features a user-friendly design; the infrared sensor automatically activates relevant functions when the user approaches, increasing convenience and comfort.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] like Figure 1 and Figure 2 As shown, a bedside refrigerator includes a refrigerator body 1 and support legs 2. The support legs 2 are fixed to the bottom of the refrigerator body 1. The main function of the support legs 2 is to support the entire refrigerator body 1 and ensure that it is placed stably in the position required by the user.

[0026] like Figure 4 As shown, the refrigerator cabinet 1 includes a cabinet body 11 and a top cover 12 that cooperates with the cabinet body 11. The top cover 12 fits tightly with the cabinet body 11, providing a good sealing effect and preventing outside air from entering the refrigerator cabinet. The top cover 12 can effectively protect the items inside the refrigerator cabinet from dust, moisture and other pollutants, maintaining the cleanliness of the internal environment.

[0027] like Figure 3 As shown, the housing 11 includes a storage box 13 and an outer shell 14, with the storage box 13 and the outer shell 14 being inner and outer sleeves. The outer shell 14 provides an additional physical protective layer for the storage box 13, preventing damage to the inner storage box and its contents due to impact or external pressure. This is particularly important for protecting sensitive medicines or other items.

[0028] The space between the placement box 13 and the outer shell 14 is filled with insulation material. This insulation material effectively reduces heat conduction, maintaining a low-temperature environment inside the refrigerator. This design improves refrigeration efficiency and reduces energy consumption. The insulation material can be polyurethane foam, polystyrene foam, or glass wool.

[0029] like Figure 5 and 6As shown, a semiconductor cooler 4 is installed on the outer casing 14. The semiconductor cooler 4 is connected to the placement box 13 via a cooling block 3. The cooling energy generated by the semiconductor cooler 4 is directly conducted to the placement box 13 through the cooling block 3, which can achieve efficient and directional cooling of the interior of the refrigerator. This method ensures that items requiring low-temperature storage can receive optimal temperature control.

[0030] The end of the semiconductor cooler 4 furthest from the cooling block 3 is connected to a heat sink 5 and a fan 6. When the semiconductor cooler 4 is working, it not only generates cooling but also heat at the other end. By connecting the heat sink 5 and the fan 6, this heat can be effectively and quickly dissipated into the external environment, preventing heat from flowing back into the refrigerator and affecting the cooling effect.

[0031] A thermoelectric cooler (TEC) is a solid-state device that operates based on the Peltier effect. It achieves heating or cooling by controlling the direction of the electric current, without requiring any moving mechanical parts or refrigerant.

[0032] Compared to traditional compressor-based refrigeration systems, semiconductor coolers contain no moving parts, making them virtually silent during operation. Furthermore, the small fans used for heat dissipation are typically designed in low-noise mode, further reducing overall operating noise, making them particularly suitable for use in quiet environments such as bedrooms.

[0033] The housing 14 is also equipped with a circuit board 7. The circuit board 7 is used to control the cooling of the semiconductor cooler 4. It controls when the semiconductor cooler 4 turns on and when it stops working.

[0034] In case of malfunction or when cleaning and maintenance are required, the separate design of the housing 13 and the outer shell 14 makes it easier for users or maintenance personnel to access internal components such as the semiconductor cooler 4, the cooling block 3, and the heat sink 5, facilitating inspection or replacement of parts.

[0035] The top cover 12 is hinged to the top of the cabinet 11. By rationally designing the weight distribution of the top cover 12 and its contact method with the cabinet 11, the top cover 12 can naturally apply a certain pressure to the opening of the cabinet 11, thereby achieving a better sealing effect. This helps prevent outside air from entering the refrigerator cabinet 1 and maintains the low-temperature environment inside.

[0036] The top cover 12 can also be fastened to the box body 11.

[0037] Preferably, appropriate sealing material, such as rubber gaskets, is added to the edge of the top cover 12 or the opening of the housing 11 to fill any possible minor gaps. This not only further improves the sealing performance but also effectively prevents dust and water damage, protecting the safety of the internal items.

[0038] The top cover 12 has a transparent panel 121. The transparent panel allows users to see the items stored inside the refrigerator without opening it, which is particularly useful for quickly finding needed medicines or other items. This feature greatly improves ease of use and efficiency, especially at night or in emergencies. Because users can directly observe the interior through the transparent panel, the need for frequent lid opening is reduced, which helps maintain the stability of the refrigerator's internal temperature and prevents temperature fluctuations caused by frequent door openings from affecting the preservation conditions of the items inside.

[0039] A light 122 is provided on the upper cover 12. The light 122 is located inside the upper cover 12. The light 122 can be a sensor light, which turns on when the cover is opened, or it can be controlled by a button on the upper cover 12. Whether controlled by a sensor or a button, the light allows users to easily view the inside of the refrigerator at night or in low light conditions. The sensor light is particularly suitable for nighttime use, automatically turning on when the user opens the cover, providing a clear view without any additional operation.

[0040] Preferably, a transparent panel 121 and a light 122 are integrated on the top cover 12. The light can be installed on the edge of the transparent panel or at the corner of the top cover 12, so that the view of the transparent panel is not blocked and sufficient light is ensured inside.

[0041] like Figure 7 As shown, the refrigerator cabinet 1 is equipped with an infrared sensor 15 and a night light 16. The infrared sensor 15 can detect when a user approaches the refrigerator cabinet and automatically trigger corresponding functions, such as turning on the night light 16. This provides users with an operating experience that does not require manual intervention, making it particularly suitable for nighttime use.

[0042] The housing 14 is also equipped with a speaker 8. The speaker 8 can be used to issue sound reminders, such as medication reminders. This is very important for patients who need to take medication on time, especially the elderly or those with chronic diseases. By setting specific time intervals, the speaker can emit a prompt tone at the set time to remind the user to take their medication on time. Combined with modern smart home systems, the speaker can be used to play voice commands or information, such as weather forecasts and the latest news, increasing the interactivity and usability of the device.

[0043] The outer casing 14 is also equipped with a working status indicator light for the user to observe.

[0044] Circuit board 7 serves as the control center of the bedside refrigerator, coordinating and managing the operation of various components. Depending on the added components, the circuit board can execute corresponding control logic to drive these components. Examples include the start / stop of the semiconductor cooler 4, the operation of the heat sink 5 and fan 6, the infrared sensor 15, and the aforementioned lighting fixtures. Circuit board 7 and the aforementioned components are all general-purpose standard parts or components known to those skilled in the art; their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods, and therefore will not be described in detail. The entire bedside refrigerator unit is connected to a power source.

[0045] The working principle of this bedside refrigerator unit is based on the synergistic effect of its various components. The detailed working process is as follows:

[0046] Temperature control: Circuit board 7 monitors the internal temperature of the refrigerator using a built-in or external temperature sensor. When the detected temperature exceeds the set value, the circuit board activates the semiconductor cooler 4, initiating the cooling process. The semiconductor cooler 4 transfers cold energy to the storage compartment 13 via the cooling block 3, thereby lowering the internal temperature of the refrigerator.

[0047] Thermal Management: During the operation of the thermoelectric cooler 4, heat is generated at the other end. To ensure cooling efficiency, this heat needs to be effectively dissipated. The circuit board 7 activates the heat sink 5 and fan 6 connected to the end of the thermoelectric cooler away from the cooling block to help dissipate heat quickly and prevent it from affecting the refrigeration effect.

[0048] User interaction and operation: When a user approaches the refrigerator, the infrared sensor 15 detects the motion signal and transmits this information to the circuit board 7. Based on this, the circuit board can trigger a series of preset operations, such as automatically turning on the night light 16.

[0049] The transparent panel 121 on the top cover 12 allows users to view the contents of the refrigerator without opening it. If a clearer view is needed, the light 122 can be manually turned on via a button, or the light can be turned on automatically when the lid is opened using an infrared sensor.

[0050] Nighttime assistance function: For nighttime use scenarios, the Night Light 16 can provide soft lighting when the ambient light is insufficient, helping users to safely find and use the refrigerator.

[0051] The speaker 8 can provide sound prompts according to different needs, such as timed medication reminders and device malfunction warnings. It can also play background music or voice commands via Bluetooth to enhance the user experience.

[0052] Circuit board 7 is not only responsible for the basic control of all the above components, but it can also integrate more advanced functions, such as remote monitoring and control through a wireless communication module, further enhancing the intelligence level of the product.

[0053] It should be noted that the semiconductor cooler 4, insulation material, lighting lamp 122, sensor lamp, infrared sensor device 15 and night light 16 in this embodiment are all general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
