refrigerator

Abstract

This refrigerator provides a solution that increases the air cooling cycle within the refrigerator, quickly balances the temperature, and reduces the refrigerator's energy consumption. [Solution] The refrigerator comprises a box body, a door, and a fan assembly. The inner wall surface of the door is provided with a mounting cavity having an opening toward the storage compartment. The fan assembly is mounted in the mounting cavity, with a portion of it protruding from the opening of the mounting cavity. By blowing air toward the storage compartment, the fan assembly increases the air cooling cycle inside the refrigerator, allowing for rapid temperature balance, thereby shortening the continuous operating time of the compressor and reducing the energy consumption of the refrigerator. Furthermore, because a portion of the fan assembly protrudes from the opening of the door mounting cavity, the thickness of the door in this embodiment of the present invention is smaller compared to a mounting method in which the fan assembly is completely fitted into the door, thereby increasing the storage space in the refrigerator.

Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration equipment, and particularly to a refrigerator.

Background Art

[0002] With the continuous improvement of people's living needs, the user's demand for the storage space of refrigerators is increasing. When the stored food increases, the space becomes more congested, the transmission of cold air is inhibited, and the time required for the cooling temperature to reach an equilibrium state becomes longer. In order to maintain the low-temperature environment inside the refrigerator, the compressor needs to continue operating for a longer time, increasing the energy consumption of the refrigerator. As a result, not only does it increase the user's electricity cost, but it also does not meet the requirements of sustainable development from the perspectives of energy utilization and environmental protection.

[0003] Therefore, reducing the energy consumption of the refrigerator is very important for improving the performance of the refrigerator, reducing the user's usage cost, and achieving the goals of energy conservation and emission reduction.

Summary of the Invention

[0004] Embodiments of the present invention provide a refrigerator that can increase the air-cooling cycle inside the refrigerator, quickly balance the temperature, and reduce the energy consumption of the refrigerator.

[0005] To achieve the above object, embodiments of the present invention provide a refrigerator. The refrigerator includes a box body, a door, and a fan assembly. The box body has a storage compartment. The door is movably connected to the box body so as to open and close the storage compartment. An attachment cavity having an opening facing the storage compartment is provided on the inner wall surface of the door. The fan assembly is attached to the attachment cavity and partially protrudes from the opening of the attachment cavity.

[0006] In the refrigerator provided in the embodiment of the present invention, the fan assembly increases the air cooling cycle within the refrigerator by blowing air toward the storage compartment, thereby quickly balancing the temperature, shortening the continuous operating time of the compressor and reducing the energy consumption of the refrigerator. Furthermore, because a portion of the fan assembly protrudes from the opening of the door mounting cavity, the door thickness in the embodiment of the present invention is smaller compared to mounting methods in which the fan assembly is fully fitted into the door, thereby increasing the storage space of the refrigerator.

[0011] To further clarify the object, technical means, and advantages of the present invention, embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0012] Where the following description relates to drawings, unless otherwise specified, the same numbers in different drawings indicate the same or similar elements.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art. Terms used herein are for the purpose of describing specific embodiments and do not limit the invention. The terms “and / or” as used herein include any and all combinations of one or more related items.

[0015] Currently, user demand for refrigerator storage space is increasing. As more food is stored, the space becomes more crowded, hindering the transfer of cold air and increasing the time it takes for the cooling temperature to reach equilibrium. To maintain the low temperature environment inside the refrigerator, the compressor needs to operate for longer periods, thus increasing the energy consumption of the refrigerator.

[0016] In contrast, an embodiment of the present invention provides a refrigerator that can increase the air cooling cycle inside the refrigerator, quickly balance the temperature, and reduce the energy consumption of the refrigerator.

[0017] Specifically, please refer to Figures 1 to 3. Figure 1 is a schematic diagram of the internal structure of the refrigerator provided in this embodiment, Figure 2 is a schematic diagram of the structure of the door and fan assembly provided in this embodiment, and Figure 3 is an exploded view of the door and fan assembly provided in this embodiment.

[0018] The refrigerator in this embodiment may be a household refrigerator (e.g., a single-door refrigerator, a two-door refrigerator, a multi-door refrigerator, etc.), a commercial refrigerator (e.g., a supermarket freezer, a dining room refrigerator, etc.), or a portable refrigerator. A portable refrigerator is a small refrigeration device that is easy to carry and can provide refrigeration or freezing functions while on the move. Hereinafter, the refrigerator in this embodiment will be described as a portable refrigerator.

[0019] The refrigerator of this embodiment comprises a box 1, a door 2, and a fan assembly 3. The box 1 can adopt a rectangular hollow structure as the outer shell support structure for the entire refrigerator. The box 1 is made of a high-strength material such as stainless steel and has excellent heat insulation performance and durability. A storage compartment 100 is provided inside the box 1. The storage compartment 100 may be a chiller compartment, refrigerator compartment, freezer compartment, etc. of the refrigerator. The size of the space of the storage compartment 100 is determined by the design capacity of the refrigerator and has good heat retention performance, and the four cavity walls are made of efficient heat retention material and can effectively reduce the dissipation of cold. Shelves or partitions for placing items may be provided inside the storage compartment 100, which is convenient for the user to classify and store different types of refrigerated items.

[0020] In this embodiment, the door 2 is movably connected to the box body 1 and may be a pull-out sliding connection or a swivel connection. Exemplarily, the door 2 and the box body 1 are rotatably connected by a door hinge. To ensure the airtightness of the storage compartment 100 when the door 2 is closed, a sealing member is provided at the contact point between the door 2 and the box body 1. A mounting cavity 200 is provided on the inner wall surface of the door 2. The opening of the mounting cavity 200 faces the storage compartment 100, and its shape and dimensions are adapted to the fan assembly 3, providing a stable mounting position for the fan assembly 3.

[0021] The fan assembly 3 is mounted within the mounting cavity 200 of the door 2, and a part thereof protrudes from the opening of the mounting cavity 200. The fan assembly 3 may be composed of a low-power consumption motor and a fan blade with a small thickness, thereby providing a stable and continuous airflow and reducing the weight of the fan assembly 3. When the fan assembly 3 starts to operate, the fan assembly 3 blows out an airflow towards the storage chamber 100, and the blown airflow can form an all-round air cooling cycle within the storage chamber 100. After the airflow is blown out from the fan assembly 3, it quickly diffuses into the storage chamber 100 and takes away the heat at each position within the storage chamber 100. For example, the airflow flows along the inner wall of the storage chamber 100, passes through the shelves on which food is placed, and bypasses the stored items, thereby quickly reducing the temperature difference that may originally exist throughout the storage chamber 100 and achieving a rapid temperature balance. Compared with the conventional natural convection method, the cold air can be more effectively and uniformly distributed to each corner within the storage chamber 100.

[0022] In a conventional portable refrigerator, after a user puts in new items or frequently opens the door 2, the temperature of the storage chamber 100 fluctuates greatly, so the compressor needs to continuously operate for a long time to return to the set temperature. In contrast, in this embodiment, due to the action of the fan assembly 3, the temperature fluctuation can be adjusted in a short time, so the operating time of the compressor is reduced. The significant reduction in the operating time of the compressor reduces the energy consumption of the refrigerator, and the endurance capacity (operable time) of the refrigerator is greatly increased. For a portable refrigerator, better endurance capacity means that in mobile usage scenarios such as outdoor travel and camping, the user does not need to frequently worry about the problem of insufficient electricity in the refrigerator, can more continuously maintain the stored items at an appropriate temperature, and provides extremely great convenience to the user.

[0023] To further accelerate the temperature of the storage chamber 100 reaching the equilibrium state, the opening of the mounting cavity 200 of this embodiment is vertically upward, and the door 2 is located at the top of the box body 1. In this way, the airflow generated by the fan assembly 3 is blown onto the bottom of the storage chamber 100 from above. Since hot air is relatively light and rises naturally, and cold air is relatively heavy and sinks naturally, the airflow blown out by the fan assembly 3 from above can follow such a law of natural convection and can more effectively promote the air circulation in the storage chamber 100. Compared with the case of blowing air horizontally, such an airflow from top to bottom can transport the cold air above downward faster, make the temperature in the storage chamber 100 more uniform, accelerate the speed of the air-cooling cycle, further shorten the time required for temperature balance, reduce the operating time and energy consumption of the compressor, and improve the endurance ability of the refrigerator.

[0024] Also, in this embodiment, a part of the fan assembly 3 protrudes from the opening of the mounting cavity 200 of the door 2. Compared with the conventional method where the fan assembly 3 is completely fitted into the door 2, this embodiment can effectively reduce the thickness of the door 2. The reduction of the thickness of the door 2 increases the refrigerating space without affecting the structural strength and functions of the whole refrigerator. In this way, the user can store more food or other items that need to be refrigerated, improving the practicality and user experience of the portable refrigerator.

[0025] Please refer to FIGS. 3 and 4. FIG. 4 is a schematic diagram of the internal structure of the door 2 and the fan assembly 3 provided in this embodiment.

[0026] In some embodiments, the fan assembly 3 is movably connected to the door 2 and can protrude into the storage chamber 100 from the opening and retract into the mounting cavity 200 from the opening. Specifically, the fan assembly 3 includes a bracket 31 and a fan 32 connected to the bracket 31. The bracket 31 is movably connected to the door 2 in the mounting cavity 200. The fan 32 is connected and fixed to the bracket 31, and for example, it may be a screw connection or an engagement connection.

[0027] The fan assembly 3 and the door 2 can be connected by the following movable connection methods. In one embodiment, the fan assembly 3 and the door 2 are connected via a guide rail slider. Sliders are provided on both sides of the bracket 31, and guide rails are provided on the corresponding inner walls of the mounting cavity 200. By engaging the sliders and guide rails with each other, the bracket 31 can slide along the guide rails within a certain range, thereby enabling the fan assembly 3 to extend and retract. Such a connection method can ensure the stability of the fan assembly 3's movement and withstand a certain lateral force, preventing the fan assembly 3 from shifting during movement. In another embodiment, the fan assembly 3 and the door 2 are connected via an expandable sleeve. An expandable sleeve structure is provided between the bracket 31 and the cavity wall of the mounting cavity 200. The inner and outer cylinders of the sleeve are connected to the bracket 31 and the cavity wall of the mounting cavity 200, respectively. The inner cylinder can freely expand and contract within the outer cylinder, thereby enabling the expansion and contraction movement of the fan assembly 3. This type of connection method provides excellent stability and sealing, and can accommodate the demands of different extension lengths.

[0028] The refrigerator further includes an elastic member 4, one end of which is connected to a bracket 31 and the other end of which is connected to the cavity wall of the mounting cavity 200. In this embodiment, the elastic member 4 plays a role in assisting the expansion, contraction, and return of the fan assembly 3. The elastic member 4 may be a spring (for example, a coil spring or a leaf spring) or a rubber member having elastic recovery ability.

[0029] A storage groove 300 is provided on the bracket 31 on the side away from the opening of the mounting cavity 200. One end of the elastic member 4 is housed in the storage groove 300. The design of the storage groove 300 ensures that the elastic member 4 does not displace laterally when compressed, thereby improving the stability of the elastic member 4's operation. The other end of the elastic member 4 abuts against the bottom wall of the mounting cavity 200. When the fan assembly 3 retracts into the mounting cavity 200, the elastic member 4 is compressed, and after the external force is removed, the elastic restoring force of the elastic member 4 causes the fan assembly 3 to protrude into the storage chamber 100 and return to its initial position. Preferably, four elastic members 4 are provided, and the four elastic members 4 are spaced apart at the bottom of the bracket 31 to provide more stable elastic force and support.

[0030] In this embodiment, the fan assembly 3 can protrude from the mounting cavity 200 into the storage chamber 100 through the opening, and can retract into the mounting cavity 200 through the opening. When the door 2 is opened or closed, or when the position of items in the storage chamber 100 needs to be adjusted, a conventional fan 32 with a fixed position may collide with these items, potentially damaging the items or the fan 32. In contrast, because the fan assembly 3 in this embodiment is extendable, it can avoid collisions by retracting into the mounting cavity 200 when encountering obstacles or approaching items in the storage chamber 100. For example, if a tall bottle is placed in the storage chamber 100, the fan assembly 3 will retract immediately after contacting the bottle, protecting both the bottle and the fan assembly 3.

[0031] Please refer to Figures 3, 4, and 5. Figure 5 is a cross-sectional view along the direction AA in Figure 2.

[0032] In some embodiments, the fan 32 is connected to a bracket 31, which plays a crucial role in supporting the fan 32 and connecting it to the mounting cavity 200 of the door 2. The bracket 31 is circular overall, and its design shape conforms to the mounting cavity 200, ensuring good fit and stability. A positioning arm 311 is provided on the edge of the bracket 31. The positioning arm 311 engages with a positioning groove 400 in the mounting cavity 200, thereby enabling the positioning and mounting of the fan assembly 3 within the mounting cavity 200 of the door 2.

[0033] In this embodiment, there are multiple position regulating arms 311. The multiple position regulating arms 311 are provided at intervals on both opposing side edges of the bracket 31. Selectively, there are specifically four position regulating arms 311. Each pair of position regulating arms 311 are provided at intervals on both opposing side edges of the bracket 31. Position regulating grooves 400 are provided on the side walls of the mounting cavity 200 for insertion of the position regulating arms 311. The position regulating grooves 400 are provided in a one-to-one correspondence with the position regulating arms 311, thereby ensuring accurate mounting and positioning of the fan assembly 3 within the mounting cavity 200. Furthermore, in the longitudinal direction of the length of the position regulating arms 311, the depth of the position regulating groove 400 on one side of the mounting cavity 200 is greater than the depth of the position regulating groove 400 on the other side of the mounting cavity 200. This design with varying depths is one of the key innovations in this embodiment and facilitates the installation and adjustment of the fan assembly 3.

[0034] When installing the fan assembly 3 into the mounting cavity 200 of the door 2, first, the two positioning arms 311 located on one side of the bracket 31 are aligned and inserted into the two relatively deep positioning grooves 400 located on one side of the mounting cavity 200. During the insertion process, the relatively deep positioning grooves 400 provide initial guidance and positioning for installation, making the installation operation easier and more accurate. After the two positioning arms 311 are fully inserted into the two relatively deep positioning grooves 400, the two positioning arms 311 on the other side of the bracket 31 move toward the other side of the mounting cavity 200, thereby gradually inserting the other two positioning arms 311 into their corresponding positioning grooves 400. In this way, the difference in depth of the positioning grooves 400 is cleverly utilized to achieve stepwise and accurate installation of the fan assembly 3 within the mounting cavity 200.

[0035] The above mounting method utilizes the engagement between the position regulating arm 311 and the position regulating groove 400 to achieve precise positioning of the fan assembly 3 in multiple directions. Compared to conventional mounting methods such as simple locking grooves or screw fixing, the engagement between the position regulating arm 311 and the position regulating groove 400 of different depths allows the fan assembly 3 to be accurately mounted in a predetermined position, controlling the error range to an extremely small range and improving mounting accuracy.

[0036] Multiple position-restricting arms 311 and corresponding position-restricting grooves 400 effectively improve the stability of the fan assembly 3 within the mounting cavity 200 by restricting the bracket 31 in different directions. In the daily use of a portable refrigerator, especially during transport, the refrigerator is subjected to various vibrations and tremors. With conventional mounting methods, the fan assembly 3 may loosen or displace, potentially affecting its normal operation. In contrast, the design of this embodiment ensures that the fan assembly 3 remains stable even in various complex operating environments, reducing vibration-induced wear and failure, and improving the overall reliability of the refrigerator.

[0037] As shown in Figure 4, in the mounting structure of the fan assembly 3 of this embodiment, the position regulating groove 400 serves to define the movable space of the position regulating arm 311. In the direction toward the storage chamber 100, the height of the position regulating groove 400 is greater than the thickness of the position regulating arm 311. When the fan assembly 3 needs to extend or retract, for example, when adjusting the layout of items in the storage chamber 100 and items come into contact with the fan assembly 3, or when the refrigerator is subjected to external vibrations, external forces acting on the fan assembly 3 push against it. Since the position regulating arm 311 is located within the position regulating groove 400, and the height of the position regulating groove 400 in the direction toward the storage chamber 100 is greater than the thickness of the position regulating arm 311, the position regulating arm 311 can move in this direction. Since the fan assembly 3 is connected to the position regulating arm 311 via a bracket, the entire fan assembly 3 can extend or retract as the position regulating arm 311 moves within the position regulating groove 400. The extension and retraction motion of the fan assembly 3 is performed within the range defined by the position regulating groove 400, thereby ensuring the directionality and stability of the fan assembly 3 during the extension and retraction process.

[0038] In some embodiments, the bracket 31 of the fan assembly 3 is provided with a guide hole 500. The guide hole 500 plays an important role in the connection process between the entire fan assembly 3 and the mounting cavity 200 of the door 2. The shape and size of the guide hole 500 are adapted to the guide post 21 of the bottom wall of the mounting cavity 200. Its shape may be circular, square, or other suitable geometric shape, and its internal dimensions are slightly larger than the external dimensions of the guide post 21, thereby allowing the guide post 21 to pass through smoothly and maintaining a certain level of engagement accuracy. The bottom wall of the mounting cavity 200 has the guide post 21. The guide post 21 is a structure that protrudes from the bottom wall of the cavity, and its overall dimensions are designed according to the mounting requirements of the fan assembly 3 and the overall structure of the refrigerator. The guide post 21 is adapted to the guide hole 500 and has a smooth surface, thereby reducing friction during the drilling process and ensuring a smooth installation process.

[0039] When installing the fan assembly 3, first, as described above, the two position-regulating arms 311 on one side of the bracket 31 are inserted into the deep position-regulating groove 400 on one side of the mounting cavity 200. In this process, as the bracket 31 moves, the position-regulating arms 311 on this side are inserted into their predetermined positions. Subsequently, the bracket 31 is moved to the other side of the mounting cavity 200, and the position-regulating arms 311 on the other side of the bracket 31 are inserted into the position-regulating groove 400 on the other side. In this process, the guide hole 500 is gradually aligned with the guide column 21. Once fully aligned, the guide column 21 is securely drilled into the guide hole 500. In this way, the installation of the fan assembly 3 into the mounting cavity 200 is completed.

[0040] In this embodiment, the engagement between the guide hole 500 and the guide column 21 is utilized to improve the mounting accuracy of the fan assembly 3. During the mounting process, the guide hole 500 and the guide column 21 provide precise positioning guides to the fan assembly 3 so that the fan assembly 3 is accurately mounted in the mounting cavity 200.

[0041] After installation is complete, the guide column 21 is drilled into the guide hole 500, providing extra support to the fan assembly 3. This effectively prevents the fan assembly 3 from being displaced or shaken within the mounting cavity 200 during use of the refrigerator, especially when the refrigerator is subjected to vibration or shaking (for example, during transport of a portable refrigerator), thereby improving the overall reliability of the refrigerator.

[0042] Since the fan assembly 3 is located in the door 2, the normal operation of the fan assembly 3 requires connection to the power supply or control system of the enclosure 1. For this purpose, as shown in Figure 3, in this embodiment, a wiring hole 600 is provided in the guide column 21 for passing the cable of the fan 32. The size of the wiring hole 600 can be designed according to the diameter and number of cables for the fan 32 to ensure that the cable passes through smoothly and is not too loose and does not shake during use. The inner wall of the wiring hole 600 is smooth, effectively preventing wear on the cable sheath during the routing process. The wiring hole 600 may be circular, oval, or other shapes suitable for the cable layout.

[0043] In this embodiment, by integrating the wiring holes 600 into the guide column 21, when installing the fan assembly 3, the cables can pass through the wiring holes 600 in the guide column 21 in an orderly manner, saving space as there is no need to create separate passages or dedicated wiring grooves for the cables. The wiring holes 600 allow the cables to be compactly arranged along the guide column 21, resulting in a more compact and streamlined internal structure for the door 2.

[0044] In some embodiments, as shown in Figure 3, the fan 32 includes a fan body and a cover 322, the fan body of the fan 32 being connected to a bracket 31, and the cover 322 being provided to cover the fan body of the fan 32. In this embodiment, the fan body of the fan 32 and the bracket 31 may be engaged and connected, with a plurality of locking parts provided on the edge of the fan body of the fan 32, and corresponding locking grooves provided on the bracket 31 to fit the locking parts. Such a connection method is simple and convenient, and the fan body of the fan 32 can be securely fixed to the bracket 31 simply by aligning the locking parts with the locking grooves and pressing them during installation. Alternatively, a screw connection may be used. In this case, screw holes are provided at corresponding positions on the fan body of the fan 32 and the bracket 31, and the two can be fixed together with appropriate screws. This connection method is highly reliable. Furthermore, a pin connection may be used. In this case, a plurality of pin holes are provided on the edge of the fan body of the fan 32, and corresponding pins are provided on the bracket 31 to fit the pin holes. During installation, simply aligning the pin holes with the pins and pressing down securely fastens the fan body 32 to the bracket 31.

[0045] In this embodiment, the cover 322 covers the body of the fan 32, protecting the body of the fan 32 and guiding the airflow. The cover 322 is provided with an air outlet 700. The air outlet 700 has a mesh structure. The mesh air outlet 700 prevents foreign matter from entering the inside of the fan 32, protects the fan blades from damage, and allows the airflow to be uniformly diffused into the storage chamber 100.

[0046] The cover 322 is further provided with an intake port 800, which communicates with the outlet port 700 via the mounting cavity 200. By providing multiple intake ports 800 and distributing them around the outlet port 700, air can enter the fan 32 from multiple directions, thereby increasing the intake volume. With multiple intake ports 800 surrounding the outlet port 700, the airflow entering the fan 32 becomes more uniform and stable, preventing a decrease in airflow due to insufficient intake or fan 32 running idle, thus ensuring normal operation of the fan 32 and a good cooling effect.
