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 3 is arranged at the chamber opening, and the door body 3 is arranged in a straight plate shape at the front side of the box body 1. The door body 3 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 1-12 As shown, the first aspect of an embodiment of the present application proposes a refrigerator, comprising: a box body 1, an inner tank 2, a door body 3, a guide rail 4 and a drawer 5, 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 door body 3 is covered on the accommodating cavity 21, the guide rail 4 is installed on the inner wall surface of the inner tank 2, and the drawer 5 is slidably connected to the guide rail 4; wherein, a through-set card hole 22 is provided on the wall surface of the inner tank 2, and a sealing surface 41 is provided on the outer wall surface of the guide rail 4, the sealing surface 41 is at least partially attached to the inner wall surface around the card hole 22, and a buckle 42 is provided on the sealing surface 41, and the buckle 42 passes through the card hole 22 and is arranged on the outside of the inner tank 2 and is connected to the inner tank 2 by a card.

[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 a door body 3 to form a closed space for storing items that need to be refrigerated or frozen. In order to facilitate classified placement and storage, as well as to increase the effective storage space, the present application sets a drawer 5 structure in the inner tank 2, and guides the drawer 5 through a guide rail 4, so that the drawer 5 can be simply and conveniently pulled out and put back. The card hole 22 opened on the inner tank 2 can be used for the buckle 42 on the guide rail 4 to penetrate, so that the positioning is achieved by the card connection between the buckle 42 and the inner tank 2. At the same time, since the sealing surface 41 on the outer side of the guide rail 4 is at least partially attached to the inner side edge of the card hole 22 during installation, the leakage of cold air from the gap between the card hole 22 of the inner tank 2 and the outer wall of the guide rail 4 can be effectively reduced during use, and there is no need to use other structures or materials to seal this part of the structure, which saves processes and reduces costs while ensuring the sealing performance.

[0053] It should be noted that, in order to make the drawer 5 to be taken out and put back more smoothly, the present application is provided with a roller on the front side of the guide rail 4, and the central shaft of the roller is fixedly installed at the entrance of the guide rail 4, so that the process of taking out and putting back the drawer 5 is changed from sliding friction to rolling friction, which can effectively improve the smoothness of use, reduce the noise during use, and extend the service life of the guide rail 4 and the drawer 5, and improve customer satisfaction. On this basis, a clamping structure that matches the roller is provided on the path of taking out and putting back the drawer 5, including but not limited to rollers, arc-shaped protrusions and other structures, so that even if the user takes out the drawer 5 with too much force, the clamping structure can still clamp the roller to prevent it from falling out of the inner liner 2. If the drawer 5 is to be removed, it is only necessary to pull out the drawer 5 to the maximum and tilt the drawer 5, so that the drawer 5 can be easily removed, so as to achieve the purpose of conveniently cleaning the ice deposited in the inner liner 2.

[0054] Generally speaking, a refrigerator has a refrigerating chamber and a freezing chamber, and a drawer 5 structure is generally provided in the refrigerating chamber and the freezing chamber. Therefore, the guide rail 4 and the drawer 5 of the present application can be respectively arranged in the refrigerating chamber and the freezing chamber to ensure stable installation and heat preservation effect.

The guide groove 43 is provided on the inner side of the guide rail 4, and the guide block 51 is provided on the outer side of the drawer 5. By moving the guide block 51 in the guide groove 43, the drawer 5 can be simply and conveniently moved along the direction guided by the guide groove 43 to complete the action of pulling out and putting back the drawer 5. Preferably, the direction in which the guide groove 43 is provided is the front-back direction of the refrigerator, so that the user can directly reach out and pull the drawer 5 forward and take out the items in the drawer 5 after opening the refrigerator door, which is convenient to use.

[0056] Specifically, Figure 2 , 12 As shown, the drawer 5 further includes a pull-out body 52, and the pull-out body 52 is provided with a receiving space 53 with a top opening. The pull-out body 52 is a square structure, and the guide block 51 is arranged on the outer side wall of the pull-out body 52. ​​The pull-out body 52 is a place for placing items in the refrigerator, which is usually a square structure, adapted to the shape of the box body 1 and the inner tank 2. The receiving space 53 of the pull-out body 52 is used to place items, and its top is open, so that the user can quickly take out and put items in the receiving space 53 after pulling out the drawer 5, which is convenient and quick to use. The guide block 51 is arranged on the outside of the pull-out body 52, and cooperates with the guide rail 4 on the inner side of the inner tank 2 to realize movement along a specified direction.

[0057] More specifically, Figure 3 , 9 As shown, there are at least two guide rails 4, and at least one guide rail 4 is provided on the left inner wall surface of the inner container 2 and the right inner wall surface of the inner container 2, and the corresponding position of the drawer body 52 is provided with the guide block 51 matching the guide rail 4. At least one guide rail 4 is provided on the left inner wall and the right inner wall of the inner container 2, so that the drawer 5 can be more stable during the movement, and the left guide block 51 and the right guide block 51 of the drawer 5 are both embedded in the guide grooves 43 on both sides to achieve stable support of the drawer 5.

[0058] More specifically, Figure 2 , 12 As shown, a handle 54 is provided on the front end surface of the drawer body 52, and the handle 54 is bent and arranged at the top of the front end surface of the drawer body 52. ​​The handle 54 is arranged on the front side of the drawer body 52, so that the user can more conveniently draw and put back the drawer 5. Preferably, the handle 54 of the drawer body 52 is a square structure with an open bottom, and the user can extend his hand into the handle 54 from the bottom and pull forward or push it back, and the front end surface of the drawer body 52 where the handle 54 is located is recessed backward, leaving installation space for the handle 54, and the structure is beautiful, and the handle 54 will not protrude forward and interfere with the door body 3.

[0059] In some embodiments of the present application, Figure 2-11 As shown, the outer wall of the guide rail 4 is provided with a limit block 44, and the inner wall of the inner liner 2 is provided with a limit groove 23 at a corresponding position. The limit block 44 is connected with the limit groove 23 by means of a snap connection, and the limit groove 23 is arranged to avoid the clamping hole 22. In order to further improve the stability and reliability of the installation of the guide rail 4, a limit block 44 is arranged on the guide rail 4 to be assembled with the limit groove 23 on the inner liner 2, and the limit block 44 is just embedded in the limit groove 23, so that the front and rear positions of the guide rail 4 are firmly fixed after assembly, and it is prevented from sliding out or shaking back and forth, thereby improving the durability of the guide rail 4 and the user experience. At the same time, the limit groove 23 and the clamping hole 22 cannot be arranged together, otherwise the function of the limit groove 23 will fail and the clamping task cannot be completed.

[0060] In some embodiments of the present application, Figure 2-11As shown, there are multiple sealing surfaces 41 and buckles 42, and the sealing surfaces 41 are sequentially arranged along the extension direction of the guide rail 4, and the buckles 42 are arranged one by one on the sealing surfaces 41. Since the refrigerator has a certain depth in the front-to-back direction, in order to ensure the stability of the clamping, multiple buckles 42 can be arranged in the extension direction of the guide rail 4, and multiple buckles 42 all pass through the clamping holes 22 and clamp with the inner tank 2. This way of clamping with multiple buckles 42 forms a larger combined force, which can further increase the clamping stability of the guide rail 4. At the same time, a sealing surface 41 is correspondingly arranged at the position of each buckle 42, ensuring the sealing between each clamping hole 22 and the inner tank 2.

[0061] Specifically, Fig.11 As shown, reinforcing ribs 45 are provided between adjacent sealing surfaces 41, and the reinforcing ribs 45 include at least one transverse reinforcing rib 45 and at least one longitudinal reinforcing rib 45, and the reinforcing ribs 45 are attached to the inner wall surface of the inner liner 2. Since there is a certain distance between each sealing surface 41, the structural strength between the two sealing surfaces 41 can be strengthened by reinforcing ribs 45, thereby improving the stability of the guide rail 4 structure, and the reinforcing ribs 45 are arranged in a cross-shaped manner, which has higher strength, and the thickness of the reinforcing ribs 45 is the same as that of the sealing surface 41, so that the reinforcing ribs 45 can also be attached to the inner side of the inner liner 2, further improving the sealing performance.

[0064] 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 a door body 3 to form a closed space for storing items that need to be refrigerated or frozen. In order to facilitate classified placement and storage, as well as to increase the effective storage space, the present application sets a drawer 5 structure in the inner tank 2, and guides the drawer 5 through a guide rail 4, so that the drawer 5 can be simply and conveniently pulled out and put back. The card hole 22 opened on the inner tank 2 can be used for the buckle 42 on the guide rail 4 to penetrate, so that the positioning is achieved by the card connection between the buckle 42 and the inner tank 2. At the same time, since the sealing surface 41 on the outer side of the guide rail 4 is completely attached to the inner side edge of the card hole 22 during installation, the leakage of cold air from the gap between the card hole 22 of the inner tank 2 and the outer wall of the guide rail 4 can be effectively reduced during use, and there is no need to use other structures or materials to seal this part of the structure. While ensuring the sealing performance, it saves processes and reduces costs.

[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 a door body 3 to form a closed space for storing items that need to be refrigerated or frozen. In order to facilitate classified placement and storage, as well as to increase the effective storage space, the present application sets a drawer 5 structure in the inner tank 2, and guides the drawer 5 through the guide rail 4, so that the drawer 5 can be simply and conveniently pulled out and put back. The card hole 22 opened on the inner tank 2 can be used for the buckle 42 on the guide rail 4 to penetrate, so that the positioning is achieved by the card connection between the buckle 42 and the inner tank 2. At the same time, since the sealing surface 41 on the outer side of the guide rail 4 is at least partially or completely attached to the inner side edge of the card hole 22 during installation, the leakage of cold air from the gap between the card hole 22 of the inner tank 2 and the outer wall of the guide rail 4 can be effectively reduced during use, and there is no need to use other structures or materials to seal this part of the structure, which saves processes and reduces costs while ensuring the sealing performance.
