Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, and in particular to a smart refrigerator based on semiconductor bidirectional temperature control without a control panel. Background Technology

[0002] Traditional household refrigerators generally use compressor refrigeration systems, which have a single function and can only achieve unidirectional cooling. During defrosting, an additional electric heating element is usually required, which is energy-intensive and causes significant temperature fluctuations in the storage compartment, making it difficult to maintain a constant temperature for food. Furthermore, compressor refrigeration systems are less effective at preventing food from freezing due to excessively cold compartments when operating in low-temperature environments.

[0003] With the development of semiconductor refrigeration technology, its application in small refrigeration equipment is gradually increasing. However, in traditional designs, semiconductor refrigeration chips are mostly used for single refrigeration scenarios, and their inherent bidirectional temperature control potential has not been fully explored. Even in some designs that utilize their heating end, it is mostly for auxiliary heat dissipation, and the characteristic of "quickly switching between hot and cold states by reversing the current direction" has not been elevated to a core, systematic intelligent control strategy to achieve the unity of multiple benefits such as defrosting, antifreeze, and precise temperature control.

[0004] Therefore, existing refrigerator technologies suffer from limitations such as rigid functional modes, low defrosting efficiency, and insufficient ability to cope with complex environments. The market urgently needs a new refrigerator system that integrates cooling and heating functions and enables intelligent mode switching. Utility Model Content

[0005] In order to overcome the shortcomings of existing refrigerators, such as limited functionality, high defrosting energy consumption, and poor environmental adaptability, this utility model provides an intelligent refrigerator based on semiconductor bidirectional temperature control without a control panel.

[0006] The technical solution of this utility model is: a smart refrigerator based on semiconductor bidirectional temperature control without control panel, including a lower outer shell, a frame, an upper outer shell, an inner shell, a decorative frame at the opening, a rear panel, a drawer compartment, an inner drawer door panel, a middle drawer plate, an outer drawer door panel, a drawer sliding mechanism, and a refrigeration and air circulation module. The inner shell is embedded and fixedly connected to the inner side of the frame. The lower outer shell has a U-shaped structure and is adapted to be installed on the lower outer side of the frame. The upper outer shell is fitted onto the top of the frame, and the upper outer shell and the lower outer shell are snapped together and closed. A decorative frame at the opening is fixedly installed on the outer periphery of the storage cavity inlet and outlet on the left side of the frame. The rear panel is installed on the decorative frame at the opening. The drawer compartment is assembled into the storage cavity of the inner shell by sliding in a pull-out manner through the drawer sliding mechanism. The inner drawer door panel, the middle drawer plate, and the outer drawer door panel are stacked and fixed along the drawer pulling direction, forming the drawer door together, and are installed at the left end opening of the drawer compartment through the inner drawer door panel. A refrigeration and air circulation module is provided at the right end of the frame.

[0007] Optionally, the material of the lower and upper shells is ABS engineering plastic, and the inner walls of both the lower and upper shells are fitted with a polyurethane insulation layer.

[0008] Optionally, the drawer lining is made of PVC foam board; the drawer lining has a cross-shaped reinforcing rib integrally molded inside.

[0009] Optionally, the drawer sliding mechanism includes a slider mounting plate, a slide rail assembly, and a drive assembly. The slide rail assembly consists of two sets, which are fixed to the front and rear sides of the bottom of the inner shell. The slider mounting plate is slidably installed between the two slide rail assemblies. The drive assembly is fixed to the top of the slider mounting plate, and the rolling end of the drive assembly makes rolling contact with the bottom of the drawer.

[0010] Optionally, the refrigeration and air circulation module includes a fan mounting bracket, a two-way temperature control module, a fan cover, and a light wire. The fan mounting bracket is fixed to the right port of the frame. The two-way temperature control module is installed on the fan mounting bracket. The two-way temperature control module integrates a semiconductor two-way temperature control unit and a fan. The fan cover is placed on the outside of the two-way temperature control module and fixed to the right port of the frame. The light wire is laid along the inner side wall of the frame, with one end electrically connected to the refrigerator terminal block and the other end extending to the top lighting area of ​​the inner shell.

[0011] Optionally, it also includes a sealing strip, which is clamped between the inner panel of the drawer door and the inner drawer.

[0012] The present invention has the following advantages: 1.

Detailed Implementation

[0020] Example: A smart refrigerator based on semiconductor bidirectional temperature control without a control panel, such as... Figures 1-5As shown, the refrigerator includes a lower outer shell 1, a frame 2, an upper outer shell 3, an inner shell 4, a decorative frame at the opening 5, a rear panel 6, a drawer compartment 7, a sealing strip 8, an inner drawer door panel 9, a middle drawer panel 10, an outer drawer door panel 11, a drawer sliding mechanism, and a refrigeration and air circulation module. The frame 2 is the core support skeleton of the refrigerator, and its inner side is fixedly connected to the inner shell 4 using an embedded assembly structure. The inner shell 4 is used to form a sealed storage cavity. The lower outer shell 1 has a U-shaped structure and is fitted onto the lower outer side of the frame 2. The upper outer shell 3 and the lower outer shell 1 have a fitting and engaging structure, and the upper outer shell 3 is fitted onto the top of the frame 2. The upper shell 3 and the lower shell 1 are snapped together to form the outer protective shell of the frame 2, isolating the internal components from the influence of the external environment. The lower shell 1 and the upper shell 3 are made of ABS engineering plastic, which has the characteristics of impact resistance and resistance to high and low temperature aging, thus improving the durability of the external protection. In addition, the inner walls of the lower shell 1 and the upper shell 3 are both covered with polyurethane insulation layers, which can further block the heat exchange between the inside and outside. Together with the inner shell 4, it enhances the overall heat preservation effect and reduces the energy consumption for heating. The outer perimeter of the storage cavity inlet and outlet on the left side of the frame 2 is fixedly installed by snap-fit. The decorative frame 5 at the opening is used to strengthen the structural strength of the inlet and outlet. A rear panel 6 is installed on the decorative frame 5. The drawer compartment 7 is an open storage container, which is assembled into the storage cavity of the inner shell 4 by sliding it out via a drawer sliding mechanism. The drawer door inner panel 9, the drawer middle panel 10, and the drawer door outer panel 11 are sandwiched and fixed together along the drawer pulling direction to form the drawer door. The inner side wall of the drawer door inner panel 9 is fixedly connected to the left opening edge of the drawer compartment 7, realizing the integration of the drawer door and the drawer compartment 7. The drawer door inner panel 9 can be connected to the rear panel 7. The front panel 6 is sealed and fitted, and the sealing strip 8 is sandwiched between the inner panel 9 of the drawer door and the inner drawer 7 to achieve sealing and heat preservation, prevent cold air leakage, and improve the heat preservation performance of the refrigerator. The inner panel 10 of the drawer is made of PVC foam board. PVC foam board is lightweight and has a certain heat preservation property, which can reduce the heat conduction of the drawer door. The inner panel 10 of the drawer has a cross-shaped reinforcing rib that is integrally formed inside. The cross-shaped reinforcing rib can improve the structural rigidity of the "sandwich" type drawer door, avoid door deformation caused by long-term pulling, and ensure the stability of the sealing fit. The right end of the frame 2 is equipped with a refrigeration and air circulation module.

[0021] like Figure 2 As shown, the drawer sliding mechanism includes a slider mounting plate 12, a slide rail assembly 13, and a drive assembly 14. The slide rail assembly 13 consists of two sets, which are fixed to the front and rear sides of the bottom of the inner shell 4 along the length direction of the inner shell 4 (the direction of drawer pulling). The slider mounting plate 12 is slidably installed between the two slide rail assemblies 13. The drive assembly 14 is a rolling guide, which is fixed to the top of the slider mounting plate 12. Its rolling end makes rolling contact with the bottom of the drawer 7, providing guiding support for the drawer 7 to be pulled out and reducing frictional resistance.

[0022] like Figures 1-5As shown, the cooling and air circulation module includes a fan mounting bracket 15, a bidirectional temperature control module 16, a fan cover 17, and a light wire 18. The fan mounting bracket 15 is a hollow support structure, which is fixed to the right port of the frame 2 by bolts. The bidirectional temperature control module 16 is installed on the fan mounting bracket 15 by bolts. The bidirectional temperature control module 16 integrates a semiconductor bidirectional temperature control unit and a fan. It realizes the cooling / heating function based on semiconductor bidirectional temperature control technology and generates directional airflow through the fan. The fan cover 17 is placed on the outside of the bidirectional temperature control module 16 and fixed to the right port of the frame 2. It is used to guide the airflow path and protect the bidirectional temperature control module 16. The light wire 18 is laid along the inner wall of the frame 2. One end is electrically connected to the refrigerator terminal block, and the other end extends to the top lighting area of ​​the inner shell 4 to provide a power supply circuit for the internal lighting device.

[0023] When the drawer is opened, the user pulls the outer panel 11 of the drawer door outward, causing the drawer door to move synchronously with the inner drawer 7. At this time, the drawer sliding mechanism is activated, and the rolling end of the drive assembly 14 maintains rolling contact with the bottom of the inner drawer 7, providing smooth guidance. The slider mounting plate 12, driven by the inner drawer 7, slides outward along the two sets of slide rail assemblies 13, allowing the inner drawer 7 to be smoothly pulled out from the storage cavity of the inner shell 4, facilitating the storage and retrieval of items. When the drawer is closed, the inner panel 9 of the drawer door and the rear panel 6 are sealed together, and the sealing strip 8 is clamped between the inner panel 9 of the drawer door and the inner drawer 7, forming an effective seal to prevent cold air leakage and improve heat preservation performance. Subsequently, the refrigeration and air circulation module is activated.

[0024] During normal operation, the semiconductor bidirectional temperature control unit of the bidirectional temperature control module 16 switches to cooling or heating mode according to the settings. The integrated fan starts synchronously to generate airflow. Under the guidance of the fan cover 17, this airflow passes through the hollow area of ​​the fan mounting bracket 15 and enters the channel formed by the frame 2 and the inner shell 4. Finally, it is evenly delivered to the storage cavity of the inner shell 4, realizing precise temperature regulation and efficient air circulation within the cavity, ensuring uniform and stable temperature. When the system intelligently determines that defrosting is needed, it will automatically switch the bidirectional temperature control module 16 to heating mode briefly. The generated hot airflow quickly melts the frost layer on the surface of the evaporator. After the melted water is discharged, the system immediately resumes cooling operation. This process is efficient and precise, minimizing temperature fluctuations inside the cabinet and achieving efficient frost-free management. In winter, it can keep beverages warm and provide a gentle heating environment for thawing food. Heating can also be achieved through the bidirectional temperature control module 16.
