DETAILED DESCRIPTION

[0041] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0042] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0043] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0044] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0045] As a common appliance in daily life, refrigerators are now widely used. Users can store food in refrigerators to prevent food from spoiling.

[0046] In this embodiment, the refrigerator includes a box body 1 and an inner container 2.

[0047] The box body 1 is used to form the overall appearance of the refrigerator. The box body 1 is roughly in the shape of a rectangular parallelepiped frame. The top of the box body 1 and the bottom of the box body 1 are opposite ends. From the top of the box body 1 to the bottom of the box body 1 is the height direction of the box body 1. The left side of the box body 1 and the right side of the box body 1 are opposite sides. From the left side of the box body 1 to the right side of the box body 1 is the width direction of the box body 1. The front side of the box body 1 and the back side of the box body 1 are opposite sides. From the front side of the box body 1 to the back side of the box body 1 is the thickness direction of the box body 1. The liner 2 is arranged in the box body 1.

[0048] A refrigerating chamber is arranged inside the inner tank 2, and the refrigerating chamber is used to place items. The refrigerating chamber has a chamber opening, and the chamber opening direction is arranged toward the front side of the box body 1. The refrigerating chamber can be a refrigerating temperature environment, a freezing temperature environment, or a normal temperature environment. A door body 4 is arranged at the chamber opening, and the door body 4 is arranged in a straight plate shape at the front side of the box body 1. The door body 4 can be connected to the box body 1 in an openable and closable manner to open or close the refrigerating chamber.

[0049] It can be understood that the refrigerator also includes a refrigeration system and an air supply system. The refrigeration system is installed in the box 1, and the refrigeration system is used to provide cold air to the refrigeration room; the refrigeration system generally refers to a closed system composed of components such as a compressor, an evaporator, a condenser, a drying filter, a return air pipe and a throttling device and a refrigerant. Each component is distributed at different positions of the box 1 according to its structural characteristics to meet the requirements of its corresponding function. The working process of the refrigeration system mainly includes a compression process, a condensation process, a throttling process and an evaporation process. The compression process is: after the power cord of the refrigerator is plugged in, when the contacts of the thermostat are connected, the compressor starts to work, and the low-temperature and low-pressure refrigerant from the evaporator is sucked into the compressor, and is compressed into a high-temperature and high-pressure refrigerant gas by the action of the compressor and then discharged into the condenser. The condensation process is: the high-temperature and high-pressure refrigerant gas exchanges heat with the external environment through the condenser, the temperature drops, and is gradually cooled to a saturated refrigerant vapor at room temperature and high pressure, and then cooled to a saturated refrigerant liquid. The throttling process is: the condensed refrigerant saturated liquid is filtered through a drying filter to remove moisture and impurities and then flows into the throttling device. The throttling device is used to throttle and reduce the pressure, and the refrigerant becomes wet steam at room temperature and low pressure. Evaporation process: The wet steam at room temperature and low pressure enters the evaporator and begins to absorb heat for gasification, which reduces the temperature of the evaporator and its surroundings, realizes refrigeration, and turns the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator returns to the compressor and repeats the above process. The energy conversion is carried out through the state change of the refrigerant, and the heat in the refrigerator is transferred to the air outside the box, thereby realizing the refrigeration cycle of the refrigerator.

[0050] The air supply system is installed in the box 1 to provide power for the flow of cold air. The air supply system generally includes a fan and a guide cavity. In some embodiments, the air inlet end of the guide cavity is arranged close to the fan, and the air outlet end of the guide cavity is arranged away from the fan. In other embodiments, the air outlet end of the guide cavity is arranged close to the fan, and the air inlet end of the guide cavity is arranged away from the fan. The fan drives the air in the guide cavity, and the evaporator is correspondingly arranged in the guide cavity. The cold air cooled by the evaporator flows along the guide cavity through the driving part of the fan. The cold air passes through the installation space formed between the inner tank 2 and the box 1, and finally enters the cold storage room to perform cooling operation on the cold storage room.

[0051] Based on the above structure, Figure 1-Figure 10As shown, the first embodiment of the present application proposes a refrigerator, characterized in that it includes: a box body 1, an inner tank 2, a lower hinge 3 and a door body 4, the inner tank 2 is installed in the box body 1, and the inner tank 2 is provided with a accommodating cavity 21 with a front opening, the lower hinge 3 is installed at the lower part of the box body 1, and the door body 4 is rotatably installed on the lower hinge 3 for opening and closing the accommodating cavity 21; wherein the lower hinge 3 has a first mounting plate 31, a second mounting plate 32 and a third mounting plate 33 which are sequentially connected and formed in a "Z" shape, and a hinge core 34 which is detachably installed on the first mounting plate 31 or the third mounting plate 33, and the second mounting plate 3 2 is installed at the lower part of the box body 1 and is located on the right side or left side of the box body 1, and the second mounting plate 32 has a first surface 321 and a second surface 322 that are symmetrically arranged front to back; when the second mounting plate 32 is installed on the right side of the box body 1, the first surface 321 is attached to the front side of the box body 1, the hinge core 34 is installed on the first mounting plate 31, and the door body 4 is rotatably installed on the hinge core 34; when the second mounting plate 32 is installed on the left side of the box body 1, the second surface 322 is attached to the front side of the box body 1, the hinge core 34 is installed on the third mounting plate 33, and the door body 4 is rotatably installed on the hinge core 34.

[0052] Based on the above technical scheme, the refrigerator of the present application has an opening on the front side of the box body 1 and an inner tank 2 is installed therein. The inner tank 2 has a accommodating cavity 21 and is closed by the door body 4 to form an enclosed space for storing items that need to be refrigerated or frozen. The door body 4 is hingedly connected to the box body 1 through a rotating connection with the lower hinge 3. The lower hinge 3 is configured in a "Z" shape. When the left and right interchangeable installations are performed, the lower hinge 3 can be directly flipped up and down 180°. After the flipping, the lower hinge 3 can still ensure that the second mounting plate 32 is stably installed on the box body 1. The detachable feature of the hinge core 34 ensures that the hinge core 34 can be removed and replaced on the first mounting plate 31 or the third mounting plate 33 when the left and right interchangeable installations are performed, thereby realizing the left-side hinge or the right-side hinge of the door body 4. The lower hinge 3 has a simple structure and is not easy to protrude from the side of the door body 4. The left-right interchangeable installation method is simple, which can effectively improve the platformization degree of the refrigerator.

[0053] It should be noted that in the installation structure of the door body 4, in addition to the lower hinge 3, there is also an upper hinge structure, and the upper hinge and the lower hinge 3 are arranged on the same side of the door body 4, and the two cooperate to achieve a stable hinge connection between the door body 4 and the cabinet 1. The drawings of this application show a refrigerator with a single-door structure. For a refrigerator with a multi-door structure, each door body 4 corresponds to a set of hinge structures, which can stably realize the rotation opening and rotation closing of each door body 4.

[0054] In order to achieve reliable installation of the lower hinge 3, a lower front beam structure is provided at the bottom of the front of the box body 1, which provides installation space for the lower hinge 3. The second mounting plate 32 of the lower hinge 3 is fixedly mounted at the position of the lower front beam. When viewed from the side of the door body 4, the lower hinge 3 is in a "Z" shape, and the height of the plate on the side close to the door body 4 is higher. More preferably, the first mounting plate 31 is connected to the second mounting plate 32 at 90°, and the second mounting plate 32 is also connected to the third mounting plate 33 at 90°, so that the second mounting plate 32 can be completely attached to the front end surface of the box body 1, making the installation of the lower hinge 3 more stable and reliable.

[0055] In some embodiments of the present application, Figure 3 , Figure 4 , Fig. 9 , Fig.10 As shown, the first mounting plate 31 is provided with a first mounting hole 311, the second mounting plate 32 is provided with a second mounting hole 323, and the third mounting plate 33 is provided with a third mounting hole 331. The second mounting plate 32 is fixed to the bottom of the box body 1 by a fastener 5 passing through the second mounting hole 323. When the second mounting plate 32 is installed on the right side of the box body 1, the hinge core 34 is passed through the first mounting hole 311; when the second mounting plate 32 is installed on the left side of the box body 1, the hinge core 34 is passed through the third mounting hole 331. A second mounting hole 323 is provided on the second mounting plate 32. The fastener 5 is driven into the box body 1 by passing the fastener 5 through the second mounting hole 323, so that the second mounting plate 32 can be stably and reliably installed, and the lower hinge 3 can be stably and reliably installed on the box body 1. The first mounting plate 31 is provided with a first mounting hole 311, and the third mounting plate 33 is provided with a third mounting hole 331. The function of the mounting holes is to install the hinge core 34. When the lower hinge 3 is installed interchangeably left and right, the lower hinge 3 is flipped 180° up and down. At this time, the hinge core 34 can be removed from the original mounting hole and replaced in another mounting hole, so that the installation position of the hinge core 34 can be replaced simply and quickly.

[0056] Specifically, Figure 3-Figure 10As shown, a fourth mounting hole 41 is opened on the right side of the bottom surface of the door body 4, a fifth mounting hole 11 is opened on the right side of the bottom of the box body 1, a sixth mounting hole 12 is opened on the left side of the bottom of the box body 1, and a seventh mounting hole 42 is opened on the left side of the bottom surface of the door body 4. When the second mounting plate 32 is installed on the right side of the box body 1, the fourth mounting hole 41 is sleeved on the hinge core 34, and the fastener 5 is installed on the second mounting hole 323 and the fifth mounting hole 11; when the second mounting plate 32 is installed on the left side of the box body 1, the seventh mounting hole 42 is sleeved on the hinge core 34, and the fastener 5 is installed on the second mounting hole 323 and the sixth mounting hole 12. When the lower hinge 3 is installed on the right side of the refrigerator, the fourth mounting hole 41 on the right side of the door body 4 is used to be rotatably connected to the hinge core 34 on the first mounting plate 31, and the door body 4 rotates around the vertical line where the hinge core 34 is located as the axis to realize the installation form of opening the door on the left side and hinged on the right side. The fifth mounting hole 11 is matched with the second mounting hole 323 on the second mounting plate 32, and the fastener 5 passes through the second mounting hole 323 and the fifth mounting hole 11 in sequence, which is used for the lower hinge 3 to be stably installed on the right lower part of the box body 1; when the lower hinge 3 is installed on the left side of the refrigerator, the seventh mounting hole 42 on the left side of the door body 4 is used to be rotatably connected to the hinge core 34 on the third mounting plate 33, and the door body 4 rotates around the vertical line where the hinge core 34 is located as the axis to realize the installation form of opening the door on the right side and hinged on the left side. The sixth mounting hole 12 is matched with the second mounting hole 323 on the second mounting plate 32, and the fastener 5 passes through the second mounting hole 323 and the sixth mounting hole 12 in sequence, which is used for the lower hinge 3 to be stably installed on the left lower part of the box body 1.

[0057] More specifically, Figure 4 , Figure 8 As shown, the fourth mounting hole 41 is provided with a first sleeve 43, and the seventh mounting hole 42 is provided with a second sleeve 44. When the second mounting plate 32 is installed on the right side of the box body 1, the first sleeve 43 is sleeved on the hinge core 34; when the second mounting plate 32 is installed on the left side of the box body 1, the second sleeve 44 is sleeved on the hinge core 34. The function of the sleeve is to reduce friction, which can improve the smoothness of the refrigerator door opening and closing, reduce wear and tear, and increase the service life of the refrigerator. In the present application, a mounting hole is provided on each of the left and right sides of the bottom of the door body 4 for matching and installing with the hinge core 34, so the first sleeve 43 and the second sleeve 44 can be directly embedded in the fourth mounting hole 41 and the seventh mounting hole 42. When the lower hinge 3 is interchanged left and right, the hinge core 34 can be directly inserted into the first sleeve 43 or the second sleeve 44, and no additional sleeve installation is required. The replacement and installation of the lower hinge 3 is more convenient and quick, and the sleeve is embedded in the mounting hole, which will not affect the appearance of the refrigerator. Furthermore, the material of the shaft sleeve is made of wear-resistant materials such as POM or nylon, which can effectively reduce friction.

[0058] Specifically, Fig. 9 , Fig.10 As shown, the distance from the center of the first mounting hole 311 to the second mounting plate 32 is equal to the distance from the center of the third mounting hole 331 to the second mounting plate 32, and the first mounting plate 31 and the third mounting plate 33 are arranged symmetrically. On the basis that the side of the lower hinge 3 is in a "Z" shape, the first mounting hole 311 and the third mounting hole 331 for replacing the hinge core 34 are arranged symmetrically front to back, and the first mounting plate 31 and the third mounting plate 33 are arranged symmetrically left to right, so that after the lower hinge 3 is flipped 180°, it becomes mirror-symmetrical left to right compared to the original shape, and the lower hinge 3 can be more conveniently installed on the box body 1 to realize its left-right interchangeability function.

[0059] In some embodiments of the present application, Figure 1-Figure 8As shown, it also includes a support portion 6 with adjustable height, and the support portion 6 is installed on the left and right sides of the bottom surface of the box body 1. The first mounting plate 31 is provided with an eighth mounting hole 312, and the third mounting plate 33 is provided with a ninth mounting hole 332. When the second mounting plate 32 is installed on the right side of the box body 1, the support portion 6 on the right side is penetrated through the ninth mounting hole 332 and installed on the bottom surface of the box body 1; when the second mounting plate 32 is installed on the left side of the box body 1, the support portion 6 on the left side is penetrated through the eighth mounting hole 312 and installed on the bottom surface of the box body 1. First of all, for a refrigerator, its compressor and other refrigeration components are generally arranged at the bottom of the box body 1. In order to ensure smooth air inflow and outflow, the bottom surface of the box body 1 should not be close to the ground. Therefore, the support part 6 is needed to lift the box body 1, so that air can enter the refrigeration components from the gap at the bottom of the box body 1 without hindrance, thereby improving the refrigeration and heat dissipation efficiency of the refrigerator; and for the present application, the support parts 6 are arranged on the left and right sides to ensure the balance of the box body 1 and prevent the box body 1 from having one side higher than the other side. At the same time, in order to further improve the stability and reliability of the installation of the lower hinge 3, the lower hinge 3 can also be fixedly installed by the support part 6. When the lower hinge 3 is installed on the right side, the first mounting plate 31 is installed with the door body 4 in the manner of inserting the hinge core 34 into the first mounting hole 311 Together, the second mounting plate 32 is installed with the box body 1 by inserting the fastener 5 into the second mounting hole 323. At this time, the third mounting plate 33 extends to the bottom surface of the box body 1. Then, the ninth mounting hole 332 can be opened on the third mounting plate 33 for the support part 6 to penetrate and be fixedly installed on the bottom surface of the box body 1. This not only does not affect the installation of the support part 6 on the right side of the box body 1, but also enables the three parts of the mounting plate of the lower hinge 3 to be stably installed, thereby improving the overall installation strength of the lower hinge 3. Similarly, when the lower hinge 3 is installed on the left side, the support part 6 is also installed on the bottom surface of the box body 1 through the lower hinge 3. The difference is that at this time, the support part 6 passes through the eighth mounting hole 312 on the first mounting plate 31, but the role it plays is the same as when it is installed on the right side. In addition, the support part 6 is height-adjustable. It is preferably connected to the box body 1 through a thread, and the height can be adjusted by rotating the support part 6.

[0060] In some embodiments of the present application, Figure 4 , Figure 8 As shown, it also includes a suction aid 7, which is installed on the bottom surface of the door body 4 and is arranged in cooperation with the lower hinge 3. The suction aid 7 has a protrusion 71, and the lower hinge 3 has a card slot 35. The protrusion 71 is installed in a card slot 35. The suction aid 7 is arranged in cooperation with the lower hinge 3. Since the suction aid 7 cooperates with the lower hinge 3 through the protrusion 71 and the card slot 35, it can ensure that the door body 4 can be closed tightly when the door closing force is large or small, thereby realizing the function of automatic door closing.

[0061] Specifically, Figure 4 , Figure 8 As shown, the suction aid 7 is a vertically symmetrical structure. When the lower hinge 3 is respectively installed on the right and left sides of the box body 1, the suction aid 7 is installed on the right and left sides of the door body 4 in a left-right mirror-symmetrical form. In order to match the left-right interchangeable installation function of the lower hinge 3, the suction aid 7 of the present application also has a left-right interchangeable function. The way to achieve this purpose is to use a vertically symmetrical structure with a left-right mirror-image installation, so that a set of left-right interchangeable lower hinge 3 structures with a suction aid 7 is obtained, the parts are highly universal, and the platformization degree is effectively improved.

[0062] In some embodiments of the present application, Figure 4 , Figure 8 , Fig. 9 , Fig.10 As shown, the bottom surface of the door body 4 is provided with a first limiting portion 45, and the lower hinge 3 has a second limiting portion 36, and the second limiting portion 36 is located on the rotation path of the first limiting portion 45. The first limiting portion 45 and the second limiting portion 36 can be connected by snapping, and since the first limiting portion 45 rotates with the rotation of the door body 4, when the door body 4 rotates to a certain angle, the first limiting portion 45 will be stuck on the second limiting portion 36, thereby limiting the door body 4 from continuing to open, thereby realizing the control of the opening angle of the refrigerator door.

[0063] like Figure 1-Figure 10 As shown, the second embodiment of the present application proposes a refrigerator, comprising: a box body 1, an inner tank 2, a lower hinge 3 and a door body 4, wherein the inner tank 2 is installed in the box body 1, and the inner tank 2 is provided with a accommodating cavity 21 with a front opening, the lower hinge 3 is installed at the lower part of the box body 1, and the door body 4 is rotatably installed on the lower hinge 3; wherein the lower hinge 3 has a first mounting plate 31, a second mounting plate 32 and a third mounting plate 33 which are sequentially connected and formed in a "Z" shape, and the second mounting plate 32 is installed at the lower part of the box body 1 The second mounting plate 32 is located on the right or left side of the box body 1, and has a first surface 321 and a second surface 322 that are symmetrically arranged front to back; when the second mounting plate 32 is installed on the right side of the box body 1, the first surface 321 is attached to the front side of the box body 1, and the door body 4 is rotatably connected to the first mounting plate 31; when the second mounting plate 32 is installed on the left side of the box body 1, the second surface 322 is attached to the front side of the box body 1, and the door body 4 is rotatably connected to the third mounting plate 33.

[0064] Based on the above technical solution, the refrigerator of the present application has an opening on the front side of the box body 1 and an inner liner 2 is installed therein. The inner liner 2 has a receiving cavity 21 and is closed by the door body 4 to form a closed space for storing items that need to be refrigerated or frozen. The door body 4 is hingedly connected to the box body 1 through a rotational connection with the lower hinge 3. The lower hinge 3 is configured in a "Z" shape. When the left and right interchangeable installations are performed, the lower hinge 3 can be directly flipped up and down by 180°. The flipped lower hinge 3 can still ensure that the second mounting plate 32 is stably installed on the box body 1. Unlike the first embodiment, the lower hinge 3 can be rotated not with the hinge core 34 as the axis, but by other means to make the door body 4 and the first mounting plate 31 or the third mounting plate 33 rotated, and the hinged connection between the door body 4 and the box body 1 can also be achieved. The lower hinge 3 has a simple structure and is not easy to protrude from the side of the door body 4. The left and right interchangeable installation method is simple, which can effectively improve the platformization degree of the refrigerator.

[0065] In summary, the refrigerator of the present application has an opening on the front side of the box body 1 and an inner tank 2 is installed therein. The inner tank 2 has a accommodating cavity 21 and is closed by the door body 4 to form an enclosed space for storing items that need to be refrigerated or frozen. The door body 4 is hingedly connected to the box body 1 through a rotating connection with the lower hinge 3. The lower hinge 3 is configured in a "Z" shape. When the left and right hinges are interchangeably installed, the lower hinge 3 can be directly flipped up and down 180°. The flipped lower hinge 3 can still ensure that the second mounting plate 32 is stably installed on the box body 1. The door body 4 is rotatably connected to the first mounting plate 31 or the third mounting plate 33, thereby realizing the left-side hinge or the right-side hinge of the door body 4. The lower hinge 3 has a simple structure and is not easy to protrude from the side of the door body 4. The left-right interchangeable installation method is simple, which can effectively improve the platformization degree of the refrigerator.

[0066] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present application. These improvements and substitutions should also be regarded as the scope of protection of the present application.
