Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a refrigerator. Background Art

[0002] A refrigerator is a common refrigeration device. A refrigeration compartment is formed inside the refrigerator body to keep food or other items at a constant low temperature. The bottom structure of the box mainly includes a bottom plate (made of metal, aluminum plastic, polypropylene, etc.) and a lower front beam. During the pre-installation stage of the box, the bottom plate and the lower front beam are overlapped. When the box is foamed later, the polyurethane foam expands to push the bottom plate and the lower front beam to fit firmly. Since the lower front beam is equipped with reinforcing iron and rollers, the overlap length between the bottom plate and the lower front beam is small (generally only 10-20mm). When the box is transported on the assembly line, the bottom plate will shake, resulting in a large gap at the overlap between the bottom plate and the lower front beam. When the box is foamed, the foam is easy to overflow from the overlap, resulting in leakage. Utility Model Content

[0050] 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.

[0051] See also Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a refrigerator, including a box shell 1 and a box liner 2, the box liner 2 is arranged in the box shell 1, and a foaming space is formed between the box liner 2 and the box shell 1, and the foaming space is used to install other component structures of the refrigerator and form a foaming insulation layer. A refrigeration chamber 21 is formed in the box liner 2 for storing food. The box shell 1 provides protection and support for the box liner 2. The box shell 1 and the box liner 2 together form a box structure, and the box structure is roughly a rectangular parallelepiped frame structure.

[0052] In some embodiments, the refrigeration compartment 21 is divided into a refrigerating compartment and a freezing compartment, and the refrigerating compartment and the freezing compartment are arranged up and down. A take-in and put-out opening is provided on one side of the refrigerating compartment 21 to facilitate taking and putting items into the refrigerating compartment 21. A box door is connected to the take-in and put-out opening, and the box door can be connected to the box shell 1 in an openable and closable manner to open or close the take-in and put-out opening. For example, the box door can be rotatably connected to the box shell 1, or can be slidably connected.

[0053] In some embodiments, the refrigerator also includes a refrigeration system (not shown) and an air supply system (not shown), and the refrigeration system and the air supply system are electrically connected to a power supply component, and the power supply component is used to supply electricity to various components of the refrigeration system and the air supply system, thereby ensuring the normal operation of the refrigeration system and the air supply system.

[0054] The refrigeration system is installed in the box shell 1, and the refrigeration system is used to provide cold air to the refrigeration chamber 21 inside the box 2. 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 in the box shell 1 according to its structural characteristics to meet the requirements of its corresponding function. The working process of the refrigeration system mainly includes compression process, condensation process, throttling process and evaporation process. The compression process is: after plugging in the power cord of the refrigerator, 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.

[0055] The air supply system is installed in the box shell 1 to provide power for the flow of cold air. The air supply system generally includes a fan and an air supply duct defined in the box shell 1. In some embodiments, the air inlet end of the air supply duct is arranged close to the fan, and the air outlet end of the air supply duct is arranged away from the fan. In other embodiments, the air outlet end of the air supply duct is arranged close to the fan, and the air inlet end of the air supply duct is arranged away from the fan. The box shell 1 also defines a duct cavity, which is connected to the air supply duct and the refrigeration chamber 21 inside the box 2, so that the air supply duct is connected to the refrigeration chamber 21 through the duct cavity. It should be noted that the box 2 is provided with an air outlet, which is used to connect the air duct cavity and the refrigeration chamber 21. The cold air generated by the refrigeration system enters the air duct cavity through the air supply duct through the operation of the fan, and flows from the air outlet to the refrigeration chamber 21 to cool the refrigeration chamber 21. It should also be noted that, in some embodiments, the air outlet is arranged on the side wall on the side opposite to the access opening of the box 2 and the refrigeration chamber 21 or on the side adjacent to the access opening of the box 2 and the refrigeration chamber 21; it should also be noted that the refrigeration system and the air supply system belong to the common knowledge technology in the field and will not be described here.

[0056] See also Figure 2As shown, in some embodiments, the refrigerator also includes a bottom plate 3 and a lower front beam 4, the bottom plate 3 is arranged at the bottom of the box shell 1, and the bottom plate 3 is in contact with the side wall of the box shell 1; the lower front beam 4 includes a lower front beam bottom plate 41 and a lower front beam side plate 42 connected to the lower front beam bottom plate 41, the lower front beam bottom plate 41 is arranged opposite to the bottom plate 3, and the lower front beam bottom plate 41 is in contact with the side wall of the box shell 1; the bottom of the box shell 1 is closed by the lower front beam bottom plate 41 and the bottom plate 3.

[0057] See also Figure 3 - Fig.18 As shown, a mounting hole 31 is opened on one side of the bottom plate 3 close to the lower front beam bottom plate 41, and a clamping structure 5 is installed at the mounting hole 31. The clamping structure 5 is clamped on the bottom plate 3, and a clamping gap is formed between the clamping structure 5 and at least one plate surface of the bottom plate 3. The side of the lower front beam bottom plate 41 close to the bottom plate 3 is clamped in the clamping gap and fits with the bottom plate 3 to close the foaming space.

[0058] Under the clamping action of the clamping structure 5, the lower front beam 4 is firmly overlapped with the bottom plate 3, thereby preventing a large gap from appearing at the overlap between the bottom plate 3 and the lower front beam 4 due to the shaking of the bottom plate 3 during transportation on the assembly line, thereby preventing the polyurethane foam in the foaming space from leaking out from the overlap between the bottom plate 3 and the lower front beam 4.

[0059] When installing the bottom plate 3 and the lower front beam 4, the lower front beam 4 and the bottom plate 3 are arranged front and back, with the access opening of the refrigerating chamber 21 facing the front side when in use, that is, the lower front beam 4 is arranged at the front side, and the bottom plate 3 is arranged at the rear side; the lower front beam side plate 42 is connected to the front side of the lower front beam bottom plate 41, and the rear side of the lower front beam bottom plate 41 overlaps the front side of the bottom plate 3. Therefore, a mounting hole 31 is opened on the front side of the bottom plate 3, and a clamping structure 5 is installed at the mounting hole 31. The clamping structure 5 passes through the mounting hole 31 and is clamped on two opposite plate surfaces of the bottom plate 3; a clamping gap is formed between the clamping structure 5 and at least one plate surface of the bottom plate 3, and the rear side of the lower front beam bottom plate 41 is clamped in the clamping gap and fits with the bottom plate 3, which can be used as another embodiment of the present application.

[0060] See also Figure 4 - Fig.14As shown, in some embodiments, the clamping structure 5 includes a first clamping member 51 and a second clamping member 52, and the first clamping member 51 and the second clamping member 52 are respectively clamped on opposite sides of the base plate 3; the first clamping member 51 is provided with a first clamping portion 511, and the second clamping member 52 is provided with a second clamping portion 521, and the second clamping portion 521 passes through the mounting hole 31 and is clamped and connected with the first clamping portion 511, so that the first clamping member 51 and the second clamping member 52 are connected and fixed, and the base plate 3 is clamped between the first clamping member 51 and the second clamping member 52, and a clamping gap is formed between the base plate 3 and the first clamping member 51 or the second clamping member 52. The clamping structure 5 is divided into two parts, namely, a first clamping member 51 and a second clamping member 52. The first clamping member 51 and the second clamping member 52 are fixed by the clamping connection between the first clamping portion 511 and the second clamping portion 521, which facilitates the disassembly and assembly of the clamping structure 5. After the lower front beam 4 and the bottom plate 3 are overlapped, the overlap between the lower front beam bottom plate 41 and the bottom plate 3 is located between the first clamping member 51 and the second clamping member 52, which ensures the firmness of the overlap between the lower front beam 4 and the bottom plate 3. In other embodiments, the first clamping portion 511 may also pass through the mounting hole 31 and be clamped and connected with the second clamping portion 521, so that the first clamping member 51 and the second clamping member 52 are fixed.

[0061] In some embodiments, the first clamping member 51 and the second clamping member 52 are both in the shape of rectangular plates. When the first clamping member 51 and the second clamping member 52 are clamped on opposite sides of the base plate 3, the first clamping member 51 and the second clamping member 52 both cover the mounting hole 31 of the base plate 3, so that the mounting hole 31 is closed to prevent the foam in the foaming space from leaking out of the mounting hole 31.

[0062] See also Fig.13 and Fig.14 As shown, in some embodiments, the first clamping member 51 and the second clamping member 52 are arranged up and down, the first clamping member 51 is located on the upper side of the bottom plate 3, and the second clamping member 52 is located on the lower side of the bottom plate 3. When the lower front beam 4 overlaps with the bottom plate 3, in order to facilitate the overlapping operation of the lower front beam 4, the lower front beam bottom plate 41 overlaps with the bottom plate 3 along the lower surface of the bottom plate 3, so that a part of the lower front beam bottom plate 41 is clamped between the second clamping member 52 and the bottom plate 3 to form a clamping gap.

[0063] See also Figure 4 - Fig.10As shown, in some embodiments, a through hole 512 is provided on the first clamping member 51, the first clamping portion 511 is provided on the outside of the through hole 512, and the second clamping portion 521 passes through the mounting hole 31 and the through hole 512 and is clamped on the first clamping portion 511. The through hole 512 is provided to provide a holding space for the second clamping portion 521, so that the clamping position of the first clamping portion 511 and the second clamping portion 521 is located on the upper side of the first clamping member 51, and does not occupy the space between the first clamping member 51 and the bottom plate 3, avoiding a large gap between the first clamping member 51 and the bottom plate 3, thereby ensuring the stability of the first clamping member 51 and the second clamping member 52 clamping the bottom plate 3. In addition, by adopting this method, the clamping operation of the first clamping portion 511 and the second clamping portion 521 is facilitated, ensuring that the second clamping portion 521 is clamped in place.

[0064] See also Figure 4 - Fig.11 As shown, in some embodiments, the first engaging portion 511 is away from the side of the first clamping member 51 ( Figure 6 The first abutting surface 5111 is provided on the second clamping member 52 (indicated as the upper side in the figure), the end of the second clamping portion 521 away from the second clamping member 52 is bent toward the first clamping portion 511 to form the abutting portion 5211, and the side of the abutting portion 5211 facing the second clamping member 52 forms a second abutting surface 52111 matching the first abutting surface 5111, and the abutting portion 5211 passes through the through hole 512 so that the second abutting surface 52111 abuts against the first abutting surface 5111. The abutment between the second abutting surface 52111 and the first abutting surface 5111 completes the clamping connection between the first clamping portion 511 and the second clamping portion 521. The first abutting surface 5111 stops the second clamping portion 521 to prevent the second clamping portion 521 from falling; at the same time, the second abutting surface 52111 stops the first clamping portion 511 to prevent the first clamping portion 511 from floating up, so that the first clamping member 51 and the second clamping member 52 are respectively clamped on the opposite sides of the bottom plate 3. With this arrangement, when assembling the clamping structure 5 in the mounting hole 31, the first clamping member 51 is placed on the upper side of the bottom plate 3, and the second clamping member 52 is placed on the lower side of the bottom plate 3, so that the abutting portion 5211 passes through the mounting hole 31 of the bottom plate 3 and the through hole 512 abuts against the first abutting surface 5111 to complete the clamping operation, which is convenient and quick to operate; and by using an external force to move the abutting portion 5211, the second abutting surface 52111 is disengaged from the first abutting surface 5111, so that the first clamping portion 511 and the second clamping portion 521 can be released from the clamping, which facilitates the disassembly of the clamping structure. In other embodiments, a slot can be provided on one side of the first clamping portion 511 facing the through hole 512, and the abutting portion 5211 of the second clamping portion 521 can be clamped in the slot, and the first clamping portion 511 and the second clamping portion 521 are clamped and connected by the cooperation of the slot and the abutting portion.

[0065] See also Figure 4 - Fig.11 As shown, in some embodiments, a guide surface 52112 is provided on one side of the abutting portion 5211 away from the second clamping member 52, and the guide surface 52112 is inclined toward the second abutting surface 52111. When the second clamping portion 521 is pushed upward into the mounting hole 31 and the through hole 512, the guide surface 52112 plays a guiding role to prevent the abutting portion 5211 and the first clamping member 51 from blocking each other and affecting the pushing operation of the second clamping portion 521. When the second clamping member 52 is pushed by artificial external force, the guide surface 52112 enters the mounting hole 31 in advance and contacts the first clamping member 51. The guide surface 52112 provides a pushing force to the first clamping member 51, so that the first clamping member 51 provides a reverse force perpendicular to the guide surface 52112 to the guide surface 52112. Since the guide surface 52112 is inclined, the reverse force provided by the first clamping member 51 to the guide surface 52112 has a horizontal component, so that the abutment portion 5211 moves horizontally in the mounting hole 31 to be opposite to the through hole 512. Continue to push the second clamping member 52, the abutment portion 5211 enters the through hole 512, and moves upward in the through hole 512. During this process, the abutment portion 5211 is stopped by the first clamping portion 511 on the outside of the through hole 512, so that the abutment portion 5211 keeps moving upward until the abutment portion 5211 is out of contact with the second clamping portion 521. The abutment portion 5211 loses the stopping effect of the first clamping portion 511 and resets itself under the action of its own elastic force, so that the second abutment surface 52111 of the abutment portion 5211 abuts against the first abutment surface 5111.

[0066] In some embodiments, the first clamping member 51 is in the shape of a rectangular plate, the first clamping portion 511 is in the shape of a block, and the first clamping portion 511 is fixed to the upper surface of the first clamping member 51, and the two can be fixed by bolts or welding. In some embodiments, the first clamping portion 511 and the first clamping member 51 can also be integrally formed. The first clamping portion 511 is arranged on the outer side of the through hole 512, and the wall surface of the first clamping portion 511 close to the through hole 512 is flush with the hole wall of the through hole 512.

[0067] In order to facilitate the smooth abutment between the second abutting surface 52111 of the abutting portion 5211 of the second clamping portion 521 and the first abutting surface 5111, in the width direction of the first clamping member 51, the length of the first clamping portion 511 is less than the length of the through hole 512, and the width of the abutting portion 5211 of the second clamping portion 521 is greater than the length of the first clamping portion 511, so that when the second abutting surface 52111 of the abutting portion 5211 abuts against the first abutting surface 5111, both ends of the second abutting surface 52111 extend outward from the first abutting surface 5111 along the width direction of the first clamping member 51, thereby ensuring the abutment stability between the second abutting surface 52111 and the first abutting surface 5111.

[0068] See also Figure 4 - Figure 6 , Fig.11 As shown, in some embodiments, the second clamping member 52 is provided with a boss 522, and the second engaging portion 521 is fixed on the boss 522; the lower surface of the first clamping member 51 is provided with a first limit block 513 and a second limit block 514, and when the first clamping member 51 and the second clamping member 52 are engaged, the first limit block 513 and the second limit block 514 are respectively against the opposite sides of the boss 522. The first limit block 513 and the second limit block 514 limit the boss 522 to prevent the second clamping member 52 from shaking significantly. The first limit block 513 and the second limit block 514 are arranged at intervals along the length direction of the first clamping member 51. The first clamping member 51 and the second clamping member 52 are on the clamping base plate 3, and the length directions of the first clamping member 51 and the second clamping member 52 are arranged along the front-to-back direction of the base plate 3 (the direction of the access opening when the refrigerating compartment 21 is in use is the front side). Therefore, the first limit block 513 and the second limit block 514 can limit the shaking of the second clamping member 52 in the front-to-back direction, and the mounting hole 31 and the through hole 512 can limit the shaking of the second clamping member 52 in its width direction.

[0069] See also Figure 4 - Figure 6 As shown, in some embodiments, the second limiting block 514 is provided with a step 5141, and the step 5141 is used to be stuck on the boss 522. The step 5141 has a first step 5141 surface facing the side of the boss 522 and a second step 5141 surface facing the top surface of the boss 522. The first step 5141 is used to limit the shaking of the boss 522 in the front-back direction, and the second step 5141 is used to stop the boss 522 from moving upward.

[0070] See also Fig.12 As shown, in some embodiments, the clamping structure 5 further includes a sealing member 53, which is fixed on the side of the first clamping member 51 or the second clamping member 52 facing the bottom plate 3, and the sealing member 53 at least covers the outer edge of the mounting hole 31, and the sealing member 53 forms a seam wall of the clamping seam. The mounting hole 31 and the overlap between the bottom plate 3 and the lower front beam bottom plate 41 are sealed by the sealing member 53 to prevent the foam in the foaming space from leaking from the mounting hole 31 or the overlap. The sealing member 53 is a sponge. The sealing member 53 is bonded and fixed to the corresponding first clamping member 51 or the second clamping member 52, which facilitates the installation of the sealing member 53. When the clamping seam is formed between the second clamping member 52 and the bottom plate 3, the sealing member 53 is fixed on the upper surface of the second clamping member 52. The sealing member 53 is provided with an avoidance hole corresponding to the boss 522. When the first limiting block 513 and the second limiting block 514 are arranged on the lower surface of the first clamping member 51, the bottom of the first limiting block 513 and the bottom of the second limiting block 514 pass through the mounting hole 31 on the bottom plate 3 and abut against the sealing member 53, so that the sealing member 53 is compressed to a certain extent.

[0071] See also Fig.13 and Fig.14 As shown, in some embodiments, a plurality of mounting holes 31 are provided on the bottom plate 3 along the width direction of the bottom plate 3, and a corresponding clamping structure 5 is installed in each mounting hole 31, and each mounting hole 31 is arranged side by side. The lower front beam 4 is clamped by a plurality of clamping structures 5 to ensure the stability of the overlap between the lower front beam 4 and the bottom plate 3. It should be pointed out that the clamping structures 5 in each mounting hole 31 are arranged in the same direction, so that the clamping seams formed by each clamping structure 5 and the bottom plate 3 are all located on the upper side of the bottom plate 3 or on the lower side of the bottom plate 3, which is convenient for clamping the rear side of the bottom plate 41 of the lower front beam.

[0072] The working process of the utility model is:

[0073] See also Fig.13 and Fig.14 As shown, the first clamping member 51 and the second clamping member 52 are assembled at the mounting hole 31, and the first clamping portion 511 and the second clamping portion 521 are engaged and connected, so that the first clamping member 51 and the second clamping member 52 are clamped on opposite sides of the bottom plate 3, and a clamping gap is formed between the second clamping member 52 and the bottom plate 3. Fig.15 - Fig.18 As shown, the lower front beam bottom plate 41 is aligned with the bottom plate 3 for assembly, and the lower front beam 4 is pushed toward the rear side so that the rear side of the lower front beam bottom plate 41 is inserted into the clamping gap to complete the overlap with the bottom plate 3, and the overlap between the bottom plate 3 and the lower front beam 4 is clamped and fixed by the first clamping member 51 and the second clamping member 52.

[0074] In summary, the embodiment of the utility model provides a refrigerator, which has a mounting hole 31 on the bottom plate 3, and a clamping structure 5 is installed in the mounting hole 31. The clamping structure 5 is clamped on the bottom plate 3 and forms a clamping gap with the plate surface of the bottom plate 3, and the side of the lower front beam bottom plate 41 close to the bottom plate 3 is clamped in the clamping gap. Under the clamping action of the clamping structure 5, the lower front beam 4 and the bottom plate 3 are firmly overlapped, so that a large gap is avoided at the overlap between the bottom plate 3 and the lower front beam 4 due to the shaking of the bottom plate 3 during transportation on the assembly line, thereby preventing the polyurethane foam in the foaming space from leaking from the overlap between the bottom plate 3 and the lower front beam 4.

[0075] The above is only a preferred embodiment of the present invention. 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 principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
