Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a packaging structure of a fuse of refrigeration equipment. Background Art

[0002] Fuses are used to detect whether the temperature is abnormal. When the temperature is abnormal, the fuse will cut off the circuit. In order to ensure the normal operation of refrigeration equipment such as refrigerators, fuses will be installed in the refrigerator. When the refrigerator is used, the fuse can quickly cut off the circuit when the temperature rises abnormally, which can prevent fire.

[0003] At present, the packaging method of fuses is: after the fuse is connected to the wire, the fuse is packaged with a PVC sleeve, and the two ends of the sleeve are sealed by welding; however, this packaging method has shortcomings, in which the PVC sleeve is relatively soft, which can easily cause stress on the fuse during transportation and installation, which may cause the fuse lead to break, the fuse body to be damaged, and other faults, resulting in a high failure rate and poor reliability;

[0004] There is also a packaging structure: the fuse is packaged with a structural part. After the fuse is installed in the structural part, it is filled with resin. This method has higher reliability, but it is more likely to cause problems such as fuse skew.

In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0074] The present application proposes a refrigeration device, comprising:

[0075] The box body 100 has a box opening on its side, a storage room communicating with the box body 100 opening is provided in the box body, a door body is connected to the box body 100, and the door body is located at the box body opening to open or close the box body opening.

[0076] The storage chamber includes a refrigerating chamber and / or a freezing chamber, and the door body may include a refrigerating door arranged in the refrigerating chamber and / or a freezing door arranged in the freezing chamber.

[0077] The box body 100 includes an outer shell 410 and an inner shell, wherein the inner shell is arranged in the outer shell 410, and an insulation layer for insulating the inner space of the inner shell is also arranged between the outer shell 410 and the inner shell.

[0078] The refrigerator 1 further includes a fuse 400, wherein the fuse 400 is disposed in the housing 100. Specifically, the fuse 400 is disposed between the outer shell 410 and the inner container.

[0079] The evaporator 200 is disposed in the box body 100 , the cavity of the evaporator 200 is disposed between the outer shell 410 and the inner tank, and the evaporator 200 is disposed in the cavity of the evaporator 200 .

[0080] The refrigerator also includes a refrigeration cycle system. The refrigeration cycle system generally includes a compressor, a condenser, a drying filter, a capillary tube, an evaporator 200 and other component structures connected by pipelines. The working process of the refrigeration cycle system includes a compression process, a condensation process, a throttling process and an evaporation process.

[0081] The compression process is as follows: when the refrigeration equipment has a refrigeration demand, the compressor starts working, the low-temperature, low-pressure refrigerant from the evaporator is sucked into the compressor, compressed into a high-temperature, high-pressure superheated gas in the compressor cylinder, and then discharged into the condenser.

[0082] The condensation process is as follows: the high-temperature, high-pressure refrigerant gas dissipates heat through the condenser, the temperature continues to drop, and it is gradually cooled into normal-temperature, high-pressure saturated steam, and further cooled into saturated liquid. The temperature no longer drops, and the pressure of the refrigerant remains almost unchanged during the entire condensation process.

[0083] The throttling process is as follows: the condensed refrigerant saturated liquid passes through a drying filter to remove moisture and impurities and then flows into the capillary tube, where it is throttled and depressurized, and the refrigerant becomes wet steam at room temperature and low pressure.

[0084] The evaporation process is as follows: the wet steam at room temperature and low pressure enters the evaporator 200, begins to absorb heat and vaporizes, lowers the temperature of the evaporator 200 and its surroundings, refrigerates the storage room, and turns the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator 200 returns to the compressor again, repeats the above process, and performs energy conversion through the state change of the refrigerant, transferring the heat in the refrigeration device to the air outside the cabinet 100, thereby realizing the refrigeration cycle of the refrigeration device.

[0085] In some embodiments of the present application, the evaporator 200 has an evaporator end plate 210 disposed at a side end.

[0086] Specifically, both sides of the evaporator 2004 are provided with evaporator end plates 210. The fuse 400 is arranged on the evaporator end plates 210.

[0087] The heating component 300 is located on one side of the evaporator 200.

[0088] In some embodiments of the present application, the heating component 300 is a heating tube, which is used for defrosting. The heating tube is heated after the evaporator 200 is frosted to defrost the evaporator 200.

[0089] A special clamping structure may be provided on the evaporator end plate 210 , so that the heating part is provided on the clamping structure on the evaporator end plate 210 .

[0090] In some embodiments of the present application, the evaporator 200 includes a refrigerant tube, the refrigerator tube may have multiple columns, and the multiple columns of refrigerant tubes are arranged in sequence along the evaporator 200 in a lateral direction, and the fuse 400 may be arranged between two adjacent columns of refrigerant tubes.

[0091] The fuse 400 is mounted on the evaporator end plate 210 and connected in series with the heating tube.

[0092] The fuse 400 is connected in series with the heating tube and can control the heater. When the temperature of the evaporator 200 is too high, the fuse 400 is disconnected so that the heating tube cannot work.

[0093] The fuse 400 is set on the evaporator end plate 210 and above the heating tube. The fuse body 420 will not be disconnected due to the fuse 400 being too close to the heating tube, causing the heating function of the evaporator 200 to fail, nor will the sensitivity of the fuse 400 be reduced due to the fuse 400 being too far from the heating tube, resulting in an increased fire risk.

[0094] In some embodiments of the present application, the fuse 400 includes a housing 410 , a fuse body 420 , a wire 430 and a connecting device 440 .

[0095] The housing 410 has a cavity formed inside. One end of the cavity is provided with an opening 411 communicating with the cavity. The opening 411 is an opening formed at one end of the cavity.

[0096] In some embodiments of the present application, the housing 410 is made of insulating material 450 , has stable dimensions and good heat-resistant insulation properties, and one end of the housing 410 is open for placing the fuse 420 , the connecting device 440 and part of the wire 430 .

[0097] A fuse 420 is disposed in the cavity, and the fuse 420 is provided with a lead;

[0098] To facilitate the connection of the fuse 420 , leads are provided at both ends of the fuse 420 .

[0099] A wire 430, one end of which is disposed in the cavity and connected to the lead wire via a connecting device 440, and the other end of which extends out of the cavity through the opening;

[0100] In some embodiments of the present application, the wire 430 includes a first wire 431 and a second wire 432 .

[0101] One end of the first wire 431 is disposed outside the housing 410 , and the other end of the first wire 431 extends into the cavity through the opening, and the other end of the first wire 431 is connected to a lead at one end of the fuse 420 .

[0102] One end of the second wire 432 is disposed outside the housing 410 , and the other end of the second wire 432 extends into the cavity through the opening, and the other end of the second wire 432 is connected to the lead at the other end of the fuse 420 .

[0103] In some embodiments of the present application, the connecting device 440 includes: a first connecting device 441 and a second connecting device 442, wherein the first connecting device 441 is disposed in the cavity, and the first connecting device 441 connects one end of the first wire 431 extending into the cavity to the lead.

[0104] The second connecting device 442 is disposed in the cavity. The second connecting device 442 connects one end of the second wire 432 extending into the cavity to the lead wire, thereby avoiding the problem of the first connecting device 441 and the second connecting device 442 leaking out.

[0105] After the fuse 420 and the connecting device 440 are assembled, the housing 410 may be filled with an insulating material 450 to insulate and seal the housing 410 .

[0106] The fuse 400 is connected to the heating component 300 and has a large current when working. If the live part of the fuse 400 is poorly insulated, there may be a risk of leakage during long-term use. The live part of the fuse 400 mainly includes a fuse body 420 and a connecting device 440 connecting the fuse body 420 and the wire 430.

[0107] The fuse 400 and the connecting device 440 are charged, and the outer shell 410 and the resin inside are protective insulation. The thicker the protective insulation layer, the safer it is. If the fuse 420 is skewed during assembly, the thickness of the protective insulation layer between the fuse 420, the connecting device 440 and the outer shell 410 becomes thinner, and there will be risks in long-term use.

[0108] In order to avoid the problem of the fuse 420 assembled in the shell 410 being skewed, in some embodiments of the present application, the refrigeration device is configured to include: a support positioning frame 500, which is inserted and fixed into the inside of the shell 410 from the opening portion 411, and is used to support and position the fuse 420 so that the center of the fuse 420 and the center of the shell 410 remain basically parallel.

[0109] By assembling a built-in support and positioning frame 500 inside the shell 410, the fuse 420 is supported and positioned to ensure that the center line of the fuse 420 and the center line of the shell 410 remain basically parallel, that is, to ensure that the fuse 420 will not be skewed to a large extent, so that the fuse 420 and the live parts of the connecting device 440 will not have their corresponding insulation layer thickness reduced due to tilting, thereby ensuring the insulation effect and effectively avoiding the problem of leakage caused by the unsupported skewness of the existing fuse 420 packaging structure.

[0110] During assembly, the support and positioning frame 500 can be inserted and fixed into the interior of the shell 410 through the opening 411 at one end of the shell 410. To facilitate the installation of the support and positioning frame 500, the maximum outer diameter of the support and positioning frame 500 should be slightly smaller than the minimum inner diameter of the shell 410 during setting.

[0111] In some embodiments of the present application, the support and positioning frame 500 includes:

[0112] The clamping portion 510 formed on the supporting and positioning frame 500 is used to clamp and fix the fuse 420, and the shape of the clamping portion 510 is adapted to the shape of the fuse 420;

[0113] During assembly, the fuse 420 is clamped into the clamping portion 510 , and is fully supported and fixed by the clamping portion 510 that matches its shape, thereby ensuring the firmness of the installation position of the fuse 420 .

[0114] In some embodiments of the present application, the support and positioning frame 500 includes:

[0115] A plurality of support and positioning portions 520 are provided, arranged circumferentially along the clamping portion 510, and abut against the inner wall of the housing 410 to fix the support and positioning frame 500 and the housing 410;

[0116] When the support and positioning frame 500 is inserted into the cavity of the shell 410, it can be firmly fixed on the wall of the shell 410 through multiple support and positioning parts 520 to ensure a firm connection between the support and positioning frame 500 and the shell 410, thereby ensuring the firmness and stability of the installation position of the fuse 420 supported and positioned by the support and positioning frame 500.

[0117] By inserting the support and positioning frame 500 inside the shell 410 and supporting and positioning the fuse 420 through the clamping portion 510 on the support and positioning frame 500, rigid support and fixation of the fuse 420 installed in the shell 410 is achieved, ensuring that the fuse 420 assembled in the shell 410 will not be skewed during use, thereby ensuring the overall insulation and reliability of the fuse 400.

[0118] The insulating material 450 is used to fill the cavity after the support and positioning frame 500 is installed in place.

[0119] In some embodiments of the present application, the insulating material 450 is a liquid resin.

[0120] Since the support and positioning frame 500 is provided in this embodiment, it is necessary to fill the liquid resin for packaging after the support and positioning frame 500 is installed and fixed. After packaging, the fuse 420 can be basically located at the center of the housing 410, thereby solving the problem of the original fuse 400 being skewed.

[0121] The liquid resin can position and solidify the support and positioning frame 500 and the fuse 420 after solidification, thereby ensuring the installation position of the fuse 420. In addition, the liquid resin can protect the fuse 420 and the lead from external forces after solidification, and will not affect the sensed temperature of the fuse 420.

[0122] The support and positioning frame 500 is built into the cavity of the outer shell 410. The support and positioning part 520 inside it is arranged in the cavity, so that there is a larger contact area between the liquid resin and the support and positioning frame 500, and the friction between the two is also larger. After the liquid resin is solidified, it can strengthen the fixation of the support and positioning part 520, thereby ensuring the firmness of the support and positioning frame 500 assembled in the outer shell 410, and further ensuring the firmness of the installation position of the fuse 420 assembled in the support and positioning frame 500, so that it will not be skewed.

[0123] In some embodiments of the present application, the support and positioning frame 500 includes:

[0124] The bracket body is a plastic part.

[0125] The supporting body is an annular body which is plastic and can be deformed without being damaged when subjected to force.

[0126] The clamping portion 510 is formed on the bracket body. The clamping portion 510 has a clamping opening 511 . The inner diameter of the clamping opening 511 is smaller than the outer diameter of the fuse 420 .

[0127] In some embodiments of the present application, the locking portion 510 is a locking groove formed on the bracket body, which is arc-shaped and adapted to the shape of the fuse 420. When the fuse 420 is locked in the locking groove, it can be wrapped and fixed in place by the locking groove.

[0128] The locking opening 511 is formed at the top of the locking groove, which is mainly used to facilitate the installation of the fuse 420 .

[0129] Since the bracket body is a plastic part with elasticity, when the fuse 420 is installed, it can be inserted into the clamping groove through the clamping opening 511 at the top. The inner diameter of the opening is smaller than the outer diameter of the fuse. When the fuse 420 is inserted, it will deform so that the fuse 420 is inserted into the clamping groove.

[0130] After the fuse 420 is locked in place, the locking opening 511 is reset after the force acting on the locking opening 511 disappears, so as to limit the fuse 420 locked in the locking slot and prevent the fuse 420 from falling out of the locking slot.

[0131] In some embodiments of the present application, the housing 410 includes:

[0132] An end stop component is arranged at one end of the housing 410 and is used to form an end cover of the housing 410;

[0133] The shell peripheral components 412 are provided in plurality, the sides of the plurality of shell peripheral components 412 are sequentially connected, and a corner positioning portion 413 is formed between the inner walls of adjacent shell peripheral components 412;

[0134] A plurality of housing peripheral components 412 are sequentially connected to form side walls of the housing 410 .

[0135] During connection, the ends of the plurality of housing peripheral components 412 and the end stop components are connected and fixed.

[0136] The opening portion 411 is formed at the other end of the plurality of shell peripheral components 412 and is arranged opposite to the end stop component.

[0137] During assembly, the support and positioning frame 500 can be inserted into the housing 410 from the opening 411 along the length direction of the housing peripheral component 412 .

[0138] In some embodiments of the present application, the shell peripheral component 412 is a shell peripheral plate, and adjacent shell peripheral plates are connected to form a corner positioning portion 413.

[0139] The corner positioning portion 413 is a corner positioning groove formed at adjacent locations of two housing outer peripheral plates.

[0140] The support positioning portion 520 is formed by extending from the bracket body, and multiple support positioning portions 520 are provided and arranged along the circumference of the bracket body. The multiple support positioning portions 520 are respectively clamped in the multiple corner positioning portions 413.

[0141] The support positioning portion 520 is a corner support positioning leg extending from the bracket body. There are multiple support positioning legs extending along the radial direction of the bracket body. The ends of the corner support positioning legs are respectively clamped in multiple corner positioning grooves to achieve the fixation of the support positioning frame 500 and the shell 410.

When any one of the corner positioning legs 521 and the side wall positioning legs 522 is not firmly positioned, the other one can ensure that the support positioning frame 500 will not move, thereby ensuring the stability of the support positioning frame 500 fixed to the outer shell 410.

[0158] In some embodiments of the present application, the housing 410 includes:

[0159] The shell peripheral component 412 is provided in plurality, and the sides of the plurality of shell peripheral components 412 are connected in sequence;

[0160] The support positioning portion 520 is a support positioning leg extending from the bracket body. There are multiple support positioning legs, and the multiple support positioning legs have the same or different lengths. The multiple support positioning legs respectively rest against the inner walls of multiple shell peripheral components 412.

[0161] In some embodiments, the support and positioning legs of the support and positioning frame 500 are only used to abut against the inner wall of the shell peripheral component 412 to achieve an assembly connection between it and the outer shell 410.

[0162] In some embodiments, four shell peripheral components 412 are provided and connected in sequence to form a cube, and four supporting positioning legs are also provided accordingly.

[0169] In some embodiments of the present application, the refrigeration device further comprises:

[0170] The sliding stopper 530 is provided in plurality, formed on a plurality of the housing peripheral components 412, and extending and arranged along the assembly direction of the support and positioning frame 500;

[0171] When the support and positioning frame 500 is assembled, it is inserted into the housing 410 by sliding along the sliding limiting portion 530 through the support and positioning portion 520 and is limited by the sliding limiting portion 530 .

[0172] In some embodiments of the present application, the sliding limiting portion 530 includes a first sliding rail and a second sliding rail arranged opposite to the first sliding rail, and a sliding channel for inserting the supporting positioning portion 520 is formed between the first sliding rail and the second sliding rail. The supporting positioning frame 500 can be slidably inserted into the interior of the outer shell 410 along the sliding channel through the supporting positioning portion 520.

[0173] The sliding limiter 530 can be used to guide the support and positioning frame 500 during assembly, so that the support and positioning frame 500 can be quickly and accurately installed in the housing 410 .

[0174] In addition, since the support positioning portion 520 is embedded in the sliding limiting portion 530, after the support positioning frame 500 slides into place, it can also be limited by the sliding limiting portion 530 to prevent its position from moving, thereby ensuring that the position of the support positioning frame 500 will not move and avoiding the fuse 420 installed therein from being skewed.

[0175] In some embodiments of the present application, the sliding limiting portion 530 is disposed at the position of the corner positioning portion 413 of the adjacent shell peripheral component 412 and is limited by the diagonal support positioning leg.

[0176] In some embodiments of the present application, the sliding limit portion 530 is arranged on at least one of the corner positioning portion 413 of the adjacent shell peripheral component 412 and the inner wall of the shell peripheral component 412, and respectively provides sliding guide limits for the corner positioning leg 521 and / or the side wall positioning leg 522.

[0177] In some embodiments of the present application, the sliding limit portion 530 is disposed on the inner wall of at least one of the plurality of shell peripheral components 412 to perform sliding guide limit on at least one of the plurality of supporting positioning legs.

[0178] In some embodiments of the present application, the housing peripheral component 412 includes a top peripheral component located at the top, a bottom peripheral component at the bottom, and side peripheral components disposed opposite to each other.

[0179] The top and bottom in this embodiment refer to that when the fuse 400 is assembled on the evaporator end plate 210, the shell peripheral component 412 located above corresponds to the top peripheral component, and vice versa, it corresponds to the bottom peripheral component.

[0180] The sliding limiter 530 is provided on two oppositely disposed side peripheral components. The sliding limiter 530 on the side peripheral components can limit the upper and lower positions of the support positioning portion 520 to prevent the support positioning frame 500 from moving up and down.

[0181] In some embodiments of the present application, in order to achieve assembly of the housing 410 and the evaporator 200 , a connecting column 415 is provided on the housing 410 for being inserted into the connecting portion 221 of the evaporator end plate 210 .

[0182] In some embodiments of the present application, the connecting column 415 is arranged on a peripheral component of the housing 410 , and can be arranged on an outer wall of any peripheral component of the housing 410 .

[0183] The connecting column 415 is used to be inserted into the connecting portion 221, and includes:

[0184] Column body 4151;

[0185] A locking protrusion 4152 is arranged at the end of the column body 4151 , the outer diameter of the locking protrusion 4152 is larger than the inner diameter of the connecting portion 221 , and a notch portion 4153 is formed on the locking protrusion 4152 to enable radial deformation.

[0186] In some embodiments of the present application, the connection portion 221 is a connection hole provided on the evaporator end plate 210 , and the connection column 415 is inserted into the end plate connection hole.

[0187] In order to enhance the connection strength of the fuse 400, a plurality of connecting posts 415 may be provided during setting, and arranged in sequence along the length direction of the peripheral components of the housing 410. Correspondingly, a plurality of connecting holes are also arranged on the evaporator end plate 210 for inserting the connecting posts 415.

[0188] During connection, the multiple connection posts 415 can be respectively inserted into the multiple connection parts 221 , so that the fuse 400 is firmly fixed on the evaporator 200 and is not easy to get loose or shift.

[0189] In some embodiments of the present application, the connecting column 415 includes a column body 4151 and a latching protrusion 4152 disposed at an end thereof.

[0190] The notch portion 4153 on the locking protrusion 4152 is a notch groove opened from the end of the locking protrusion 4152 along the axial direction of the connecting column 415 .

[0191] When the shell 410 and the side plate of the evaporator 200 are assembled, the protrusion 4152 at the end of the connecting column 415 first passes through the connecting hole. Since the outer diameter of the protrusion 4152 is larger than the inner diameter of the connecting hole, and a notch 4153 is provided at the end of the protrusion 4152, when the protrusion 4152 passes through the connecting hole, it will be compressed through the notch 4153 to produce radial deformation, thereby ensuring that the protrusion 4152 can smoothly pass through the connecting hole. After the protrusion 4152 passes through the connecting hole, the column body 4151 is inserted into the connecting hole. At this time, the protrusion 4152 comes out of the connecting hole. Since the radial force applied to the protrusion 4152 disappears, the protrusion 4152 will restore its deformation and radially reset, and then get stuck on the side of the end of the evaporator 200 to limit the column body 4151 and prevent it from coming out of the evaporator end plate 210.

[0192] In some embodiments of the present application, a limited abutment portion 414 is provided on the outer wall of the housing 410, which is used to abut against the side wall of the evaporator end plate 210. A first direction force is applied to the evaporator end plate 210 through the limited abutment portion 414, and a second direction force is applied to the end of the evaporator 200 through the protrusion 4152. The first direction and the second direction are opposite, so that the housing 410 and the evaporator end plate 210 are firmly fixed by two opposite direction forces.

[0193] In some embodiments of the present application, the limiting abutment portion 414 is a limiting abutment protrusion extending from the outer wall of the outer shell 410, wherein when the connecting column 415 is inserted into the connecting hole of the evaporator end plate 210, the limiting abutment protrusion abuts against the outer wall of the evaporator end plate 210.

[0194] There may be multiple groups of position-limiting abutment protrusions, the groups of position-limiting abutment protrusions and the connecting posts 415 are arranged alternately, and the number of groups of position-limiting abutment protrusions is greater than the number of connecting posts 415, and there is at least one position-limiting abutment protrusion in each group.

[0195] The limiting abutting protrusion may be perpendicular to the housing 410 , and the connecting column 415 may also be perpendicular to the housing 410 .

[0207] The connecting portion is used to fix the supporting and positioning frame 500 to the outer shell 410 when the supporting and positioning frame 500 is assembled into the outer shell 410 .

[0208] In some embodiments, the connecting portion is a connecting support leg, which is evenly arranged along the circumference of the bracket body. When the support positioning frame 500 is slidably inserted into the shell 410, it can be fixed by supporting it against the inner wall of the shell 410 through the connecting support leg.

[0209] In some embodiments, the connecting portion is an elastic connecting leg, which is elastic and is compressed into the shell 410 during assembly. A corresponding insertion hole is provided on the shell 410. After the elastic connecting leg moves into place, it automatically pops out into the insertion hole to achieve positioning.

[0213] During installation, the end portion compresses the second leg and the elastic member. After installation is in place, under the action of the elastic member, the second leg pops out and is locked into the insertion hole to achieve locking and fixation.

[0214] The insulating material 450 is used to be filled into the housing 410 after the support and positioning frame 500 is installed in place.
