Description

Technical Field

[0001] This invention relates to the field of home appliances, and in particular to an anti-tipping refrigerator. Background Technology

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is also a consumer product that keeps food or other items in a constant low-temperature state. The refrigerator contains a compressor and an ice maker for freezing, and is a storage box with a refrigeration unit.

[0003] Most household refrigerators are rectangular in shape, with their height significantly exceeding their width and length. This makes them highly susceptible to tipping over during transport and use due to instability. Once tipped over, internal electrical components are easily damaged, and the outer casing may shatter, resulting in substantial financial losses. Therefore, there is an urgent need to design an anti-tipping structure for refrigerators to address these issues. Summary of the Invention

[0043] The refrigerator of this embodiment is a storage device that includes a refrigeration system. The refrigeration system can be a common compression refrigeration system, which provides cooling capacity to the storage compartment through, for example, direct cooling and / or air cooling, to maintain the desired storage temperature in the storage compartment. The refrigerator generally includes a cabinet 10 and a door.

[0044] The enclosure 10 defines at least one front-opening storage compartment, typically multiple, such as a refrigerator compartment, freezer compartment, and variable-temperature compartment. The specific number and function of the storage compartments can be configured according to pre-defined needs. In some embodiments, the storage temperature of the refrigerator compartment can be 2–9°C or 4–7°C; the storage temperature of the freezer compartment can be -22–-14°C or -20–16°C. The freezer compartment is located below the refrigerator compartment, and the variable-temperature compartment is located between the freezer and refrigerator compartments. The temperature range inside the freezer compartment is generally -14°C to -22°C. The variable-temperature compartment can be adjusted as needed to store suitable food or serve as a fresh-keeping storage compartment.

[0045] The refrigerator body 10 consists of an outer shell, an inner liner, a door, an insulation layer, and accessories. The refrigerator body 10 is the outer structure of the refrigerator, protecting the entire refrigerator. To prevent heat conduction from the outside environment, insulation layers are added between the outer shell and the inner liner, and between the door panel and the inner liner. The structure of the refrigerator body 10 directly affects the refrigerator's power consumption, appearance, lifespan, and performance.

[0046] The refrigeration system can be a refrigeration cycle system consisting of a compressor, condenser, throttling device, and evaporator. The evaporator is configured to provide cooling capacity directly or indirectly to the storage compartment. For example, when the refrigeration unit is a household compression-type direct-cooling refrigerator, the evaporator can be located on the outer or inner side of the rear wall of the refrigerator's inner liner. When the refrigeration unit is a household compression-type air-cooling refrigerator, the cabinet 10 also has an evaporator chamber, which is connected to the storage compartment via an air duct system. An evaporator is installed in the evaporator chamber, and a fan is installed at the outlet to circulate cooling to the storage compartment.

[0047] A compression refrigeration system releases cooling capacity through a refrigerant compression cycle via its evaporator. A compression refrigeration system generally has four main components: a compressor, a condenser, a throttling device, and an evaporator. The evaporator directly or indirectly provides cooling capacity to the storage room. Its working principle is as follows: the compressor, driven by an electric motor, continuously rotates, drawing vapor from the evaporator and increasing the pressure and temperature of the refrigerant vapor through compression. This creates conditions for transferring heat from the refrigerant vapor to the external environment, compressing the low-temperature, low-pressure refrigerant vapor to a high-temperature, high-pressure state.

[0048] A condenser is a heat exchange device that uses the ambient temperature to cool the refrigerant and removes the heat from the high-temperature, high-pressure refrigerant vapor from the compressor, thus cooling and condensing the high-temperature, high-pressure refrigerant vapor into a high-pressure, room-temperature refrigerant liquid.

[0049] High-pressure, room-temperature refrigerant liquid passes through a throttling element to become low-temperature, low-pressure refrigerant, which is then sent into the evaporator to absorb heat and evaporate. Based on the principle of the correspondence between saturation pressure and saturation temperature, reducing the pressure of the refrigerant liquid can lower its temperature.

[0050] As another heat exchange device, the evaporator allows the low-temperature, low-pressure refrigerant liquid after throttling to evaporate (boil) into vapor, absorbing heat from the surroundings and lowering the ambient temperature to achieve the purpose of refrigeration.

[0051] Refrigerators are prone to tipping over when subjected to external forces, posing a danger to users' safety. The tipping-proof refrigerator of this embodiment can ensure that the refrigerator will not tip over when subjected to external forces.

[0052] The anti-tipping refrigerator of this embodiment includes a cabinet 10, a position sensor 900, and an anti-tipping structure. The position sensor 900 is used to detect whether the refrigerator is tilted. The anti-tipping structure is pivotally connected to the cabinet 10, and a suction cup 700 is provided at one end. The anti-tipping structure is configured to rotate relative to the cabinet 10 when the refrigerator is tilted, so that the suction cup 700 adheres to the wall to prevent the refrigerator from tipping over. The position sensor 900 can detect that the refrigerator is tilted when it is at any position 20cm off the ground.

[0053] The refrigerator in this embodiment may further include a fixed rotating shaft 500. The fixed rotating shaft 500 is fixedly connected to the cabinet 10. The anti-tipping structure may further include a suction cup connecting rod. The suction cup connecting rod is pivotally connected to the fixed rotating shaft 500, and a suction cup 700 is provided at one end of the suction cup connecting rod.

[0054] The anti-tipping structure also includes a support rod 400. The other end of the support rod 400 is pivotally connected to the suction cup connecting rod. The support rod 400 is configured to extend from the refrigerator body 10 to support the refrigerator and prevent it from tipping over when the refrigerator is tilted. The anti-tipping structure also includes a movable pivot 300. The movable pivot 300 connects the support rod 400 and the suction cup connecting rod, allowing the support rod 400 and the suction cup connecting rod to be pivotally connected.

[0055] The front end of the support rod 400 is provided with an inclined support surface, and the inclination angle of the inclined surface can be set according to actual needs.

[0056] The suction cup connecting rod may include a first connecting section 610, a second connecting section 620, and a third connecting section 630. The first connecting section 610, the second connecting section 620, and the third connecting section 630 are connected at an angle to ensure that, under normal use, one end of the first connecting section 610 is connected to the support rod 400, and the first connecting section 610 is pivotally connected to the fixed rotating shaft 500. The second connecting section 620 is formed by extending at an angle from the other end of the first connecting section 610 towards the outside of the housing 10. The third connecting section 630 is formed by extending at an angle from the end of the second connecting section 620 towards the housing 10. A suction cup 700 is provided at the end of the third connecting section 630.

[0057] The box 10 has a front opening on the front side so that the support rod 400 can extend out of the box 10 from the front opening. The box 10 has a rear opening on the rear side so that the suction cup 700 extends out of the box 10 from the rear opening.

[0058] The anti-tipping refrigerator of this embodiment also includes a controller 100. The controller 100 is disposed inside the cabinet 10 and is used to control whether the anti-tipping structure rotates relative to the cabinet 10. The controller 100 may include an electromagnetic pneumatic top 200, which is connected to the anti-tipping structure and configured to extend when the refrigerator tilts so that the anti-tipping structure rotates relative to the cabinet 10.

[0059] The housing 10 may have a receiving cavity 800, and the anti-tipping structure is disposed within the receiving cavity 800. The receiving cavity 800 may include a horizontally arranged support rod receiving cavity and a vertically arranged suction cup connecting rod receiving cavity. The front side of the support rod receiving cavity is connected to the front opening, and the rear side of the connecting rod receiving cavity is connected to the rear opening.

[0060] When the position sensor 900 detects that any position of the refrigerator is more than 20cm off the ground, the controller 100 controls the electromagnetic pressure top 200 to extend, causing the anti-tipping structure to activate. The suction cup 700 pops out and adheres to the wall, and the support rod 400 extends forward. The suction cup 700 and the support rod 400 work together to prevent the refrigerator from tipping over.

[0061] The refrigerator in this embodiment can have two anti-tipping structures arranged opposite each other on both sides of the horizontal axis to further enhance its anti-tipping capability.

[0062] The anti-tipping refrigerator of this embodiment includes a cabinet 10, a position sensor 900, and an anti-tipping structure. The position sensor 900 is used to detect whether the refrigerator is tilted. The anti-tipping structure is pivotally connected to the cabinet 10, and a suction cup 700 is provided at one end. The anti-tipping structure is configured to rotate relative to the cabinet 10 when the refrigerator is tilted, so that the suction cup 700 adheres to the wall to prevent the refrigerator from tipping over.

[0063] Furthermore, the anti-tipping structure of the refrigerator in this embodiment also includes a support rod 400. The other end of the support rod 400 is pivotally connected to the suction cup connecting rod, and the support rod 400 is configured to extend out of the cabinet 10 to support the refrigerator and prevent it from tipping over when the refrigerator tilts.

[0064] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
