Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of refrigeration equipment, and in particular to a refrigerator. Background Art

[0002] The refrigerator comprises a box body and a door body. The box body is formed with a accommodating cavity with a front opening. The door body is rotatably arranged on the front side of the box body, and the door body is used to close or open the accommodating cavity.

[0003] In the related art, a Hall sensor is provided on the front wall of the refrigerator body, and a magnet capable of triggering the Hall sensor is provided on the frame of the door body facing the front wall of the body. The opening and closing state of the door body is detected by the cooperation of the Hall sensor and the magnet, so as to issue a prompt when the door is closed abnormally, thereby reducing the energy consumption of the refrigerator caused by abnormal door closing.

[0004] However, since the door body has a sealing strip on the side facing the front wall of the box, when the door body is closed, the sealing strip is enclosed between the front wall of the box and the door frame. Therefore, there is a large gap between the frame where the magnet is located and the front wall of the box, resulting in a large attenuation of the magnetic force of the magnet in the process of transmission to the Hall sensor, thereby reducing the accuracy of the Hall sensor in detecting the switch status of the door body. Utility Model Content

[0005] The embodiment of the present application provides a refrigerator that can solve the technical problem of low accuracy of the magnetic sensor of the related refrigerator in detecting the door switch state.

[0006] The present application provides a refrigerator, comprising:

[0007] The box body is structured with a refrigeration compartment, a take-in and put-out opening is formed on the front side of the refrigeration compartment, and the front side of the box body has a box front wall;

[0008] The first door body is rotatably connected to the box body to open or close the refrigeration compartment. The outer periphery of the first door body has a first door frame. When the first door body closes the refrigeration compartment, a convex structure is constructed on the side of the first door frame facing the box front wall. The convex structure protrudes toward the box front wall and is spaced from the box front wall along the depth direction of the refrigerator. The first door body includes a first elastic vibration damper, which is arranged on the convex structure. When the first door body closes the refrigeration compartment, at least part of the first elastic vibration damper is located between the convex structure and the box front wall.

[0009] A first accommodating cavity is configured on a side of the convex structure away from the front wall of the box, the first accommodating cavity is recessed toward the front wall of the box, and the first accommodating cavity is communicated with the space inside the first door body;

[0010] A first magnetic member is disposed on the first door frame, and at least a portion of the first magnetic member is accommodated in the first accommodation cavity;

[0011] A magnetic sensor component is disposed on the front wall of the cabinet. The magnetic sensor component cooperates with the first magnetic member to detect the magnetic field strength exerted by the first magnetic member on the magnetic sensor component.

[0012] In the refrigerator of this embodiment, this part of the first magnetic member disposed in the first accommodating cavity protrudes from the outer side wall of the first plate body. Compared with the implementation manner of directly disposing the first magnetic member inside the first plate body, the first magnetic member of the present application is closer to the front wall of the cabinet, reducing the distance between the first magnetic member and the magnetic sensor component, enhancing the magnetic field strength exerted by the first magnetic member on the magnetic sensor component, making it easier for the first magnetic member to trigger the magnetic sensor, and improving the accuracy of the magnetic sensor in detecting the opening and closing state of the first door body.

[0013] In some embodiments of the present application, the first door frame includes a first plate body and a second plate body. When the first door body closes the refrigerating compartment, the first plate body faces the front wall of the cabinet, the second plate body is adjacent to the lower part of the first plate body, and the second plate body extends in a direction away from the front wall of the cabinet compared with the first plate body;

[0014] The convex structure is disposed on the first plate body;

[0015] A second accommodating cavity is constructed inside one end of the second plate body close to the first plate body. The second accommodating cavity communicates with the first accommodating cavity, and at least part of the first magnetic member is disposed in the first accommodating cavity and the second accommodating cavity.

[0016] With such a setting, since the second accommodating cavity is constructed inside the second plate body, the thickness of the second plate body corresponding to the second accommodating cavity is reduced. When the first magnetic member is disposed in the second accommodating cavity, the shielding thickness of the second plate body for the first magnetic member is reduced, thereby reducing the attenuation of the magnetic force of the first magnetic member during the transmission to the magnetic sensor, making it easier for the first magnetic member to trigger the magnetic sensor, and improving the accuracy of the magnetic sensor in detecting the opening and closing state of the first door body.

[0017] In some embodiments of the present application, the second plate body is provided with a first through hole, the first through hole communicates with the second accommodating cavity, and the first through hole corresponds to part of the first magnetic member.

[0018] With such a setting, by providing the first through hole on the second plate body, the shielding of the second plate body for the first magnetic member can be further reduced, reducing the attenuation of the magnetic force of the first magnetic member during the transmission to the magnetic sensor, making it easier for the first magnetic member to trigger the magnetic sensor, and improving the accuracy of the magnetic sensor in detecting the opening and closing state of the first door body.

[0019] In some embodiments of the present application, a reinforcing protrusion is constructed on the outer side of the second plate body. The reinforcing protrusion corresponds to the second accommodating cavity and protrudes in a direction away from the second accommodating cavity.

[0020] In this way, after a reinforcing protrusion is set on the outer side of the second plate body corresponding to the second accommodating cavity, the total thickness of the second plate body and the reinforcing protrusion is increased compared to the thickness of the second plate body. Therefore, the depth of the second accommodating cavity constructed on the inner side of the second plate body is increased, thereby improving the firmness of the second accommodating cavity to fix the first magnetic component.

[0021] In some embodiments of the present application, the circumferential side wall of the protrusion structure is configured with a slot;

[0022] The first elastic vibration damping member includes a connecting portion and a vibration damping portion, the connecting portion is structured to form a third accommodating cavity with an opening, the opening of the third accommodating cavity faces the protruding structure, and a portion of the protruding structure is clamped in the third accommodating cavity through the opening;

[0023] The edge of the connecting portion close to the opening is bent toward the opening to form a bent portion, and the bent portion is clamped in the clamping slot;

[0024] The vibration-damping part is arranged on a side of the connecting part away from the protruding structure. When the first door closes the refrigerating compartment, the vibration-damping part elastically abuts against the front wall of the box.

[0025] With such arrangement, when the door closes the refrigeration compartment, the vibration-damping part elastically abuts against the front wall of the cabinet to buffer the closing force of the door, reduce the vibration amplitude of the door when closing, and make the door close more smoothly.

[0026] In some embodiments of the present application, the front wall of the box is configured with a mounting opening;

[0027] The magnetic sensor assembly includes a mounting box, a magnetic sensor and a connecting harness;

[0028] The installation box includes a box body, a first stopper and a second stopper;

[0029] The box body is arranged through the installation opening, and the side wall of the box body is configured with a wiring harness opening, which is located on the inner side of the front wall of the box;

[0030] The first stopper is located outside the box front wall and is arranged at one end of the box body away from the box front wall, and the periphery of the first stopper extends to the outside of the box body;

[0031] The second stopper is arranged on the peripheral side of the box body, the second stopper is located on the inner side of the box front wall, and the box front wall is clamped between the first stopper and the second stopper;

[0032] The second stopper has a guide slope on one side facing away from the first stopper, and the distance between the guide slope and the box body gradually increases from an end away from the first stopper to an end close to the first stopper;

[0033] The magnetic sensor is arranged in the box body;

[0034] The connecting wire harness is electrically connected to the magnetic sensor, and the connecting wire harness is passed through the wire harness opening.

[0035] In this arrangement, the box body is clamped on the front wall of the box, and the magnetic sensor is arranged in the box body. The box body protects the magnetic sensor and reduces the possibility of the magnetic sensor being damaged by collision.

[0036] In some embodiments of the present application, the first stopper is a stop plate, and the first stopper is in contact with the front wall of the box.

[0037] With such arrangement, since the thickness of the first stopper is relatively small, the thickness of the first stopper protruding from the front side of the front wall of the refrigerator is reduced, thereby reducing the influence of the magnetic sensor component on the opening and closing of the refrigerator door.

[0038] In some embodiments of the present application, the end of the box body facing away from the first stopper has a placement opening, the harness opening is connected to the placement opening, and the magnetic sensor is arranged in the box body via the placement opening;

[0039] The magnetic sensor component also includes a sealing piece, which is sealed in the placement opening.

[0040] With such arrangement, the blocking member blocks the placement opening to restrict the magnetic sensor within the box body, making it difficult for the magnetic sensor to be removed from the box body.

[0041] In some embodiments of the present application, the refrigeration compartment includes a refrigeration compartment located at the upper part of the box body and a refrigeration compartment located at the lower part of the box body; the first door body opens or closes the refrigeration compartment located at the upper part of the box body;

[0042] The refrigerator also includes:

[0043] The second door body is located below the first door body and is rotatably connected to the box body to open or close the refrigeration compartment located at the lower part of the box body. The outer periphery of the second door body is provided with a second door frame. The second door frame has a third plate body and a fourth plate body at one end close to the first door body. When the second door body closes the refrigeration compartment, the third plate body faces the front wall of the box, the fourth plate body is adjacent to the top of the third plate body, the fourth plate body extends away from the front wall of the box compared to the third plate body, a fourth accommodating cavity is configured on one side of the fourth plate body facing the inside of the second door body, a second through hole is opened on the third plate body, and the second through hole is communicated with the fourth accommodating cavity;

[0044] The second magnetic member is disposed in the fourth accommodating cavity, a portion of the second magnetic member corresponds to the second through hole, and the second magnetic member cooperates with the magnetic sensor component so that the magnetic sensor component detects the magnetic field strength of the second magnetic member acting on the magnetic sensor component.

[0045] With such arrangement, the second magnetic member cooperates with the magnetic sensor component, so that the magnetic sensor component can detect the intensity of the magnetic field applied by the second magnetic member to the magnetic sensor component.

[0046] In some embodiments of the present application, the refrigerator further includes a second elastic damping member, which is disposed at one end of the second door frame away from the first door body. When the second door body closes the refrigerating compartment, the second elastic damping member elastically abuts against the front wall of the refrigerator.

[0047] With such a setting, when the second door bodies are both in the closed state, the second elastic damping members provided on the second door bodies elastically abut against the front wall of the refrigerator below the refrigerating compartment at the lower part of the refrigerator body, so as to buffer the closing force of the second door bodies, reduce the vibration amplitude when the second door bodies are closed, and make the second door bodies more stable when closed.

An embodiment of the present application provides a refrigerator. The magnetic sensor component is arranged on the front wall of the refrigerator. A convex structure is formed on one side of the first door body facing the front wall of the refrigerator. The first elastic damping member is arranged on the convex structure. By forming a first accommodating cavity on the side of the convex structure facing away from the front wall of the refrigerator and arranging at least a part of the first magnetic member in the first accommodating cavity, not only the internal space of the convex structure is utilized, but also the distance between the first magnetic member and the magnetic sensor component is reduced, the magnetic field intensity of the first magnetic member acting on the magnetic sensor component is enhanced, making it easier for the first magnetic member to trigger the magnetic sensor, and improving the accuracy of the magnetic sensor in detecting the opening and closing state of the first door body.

[0101] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0102] It should be noted that the "front side" in the embodiments of the present application refers to the side facing the user when the refrigerator is in normal use.

A take-out opening may be formed on the front side of the refrigeration compartment 111, and a user may place items into the refrigeration compartment 111 through the take-out opening, or take items out of the refrigeration compartment 111 through the take-out opening. The refrigerator may also include a door body 20, and the door body 20 may be rotatably connected to the box body 10 to open or close the refrigeration compartment 111. The refrigerator may also be provided with a refrigeration device, which may be provided in the box body 10 to provide coldness to the refrigeration compartment 111.

[0104] The box body 10 may include a box liner 110 and a box shell 120. The box liner 110 may be configured with a refrigeration compartment 111. The box shell 120 may be connected to the outside of the box liner 110 to form the appearance of the refrigerator. The box body 10 may also include a box insulation layer, which may be arranged between the box liner 110 and the box shell 120. The box insulation layer can keep the refrigeration compartment 111 warm, so as to minimize the heat exchange between the refrigeration compartment 111 and the outside of the refrigerator, which is conducive to ensuring the refrigeration effect of the refrigerator.

[0105] For example, reference Figure 1 The box body 10 may include a box front wall 130 located at the front side. The access opening may be located at the front side of the box body 10, for example, the access opening may be formed on the box front wall 130.

The door frame 220 surrounds the periphery of the door inner liner 210 and the door panel 260. The door inner liner 210, the door frame 220, and the door panel 260 enclose to form the appearance of the door body 20. The door frame 220 can be rotatably connected to the box body 10. The door body 20 can further include a door heat insulation layer, and the door heat insulation layer can be arranged between the door inner liner 210 and the door panel 260.

When the door body 20 is in the closed state, at least part of the elastic shock absorber 280 is located between the convex structure 242 and the front wall 130 of the box, so as to buffer the closing force of the door body 20, reduce the vibration amplitude when the door body 20 closes, and make the door body 20 closer smoothly when it closes.

[0119] Exemplarily, reference Figure 5 As shown in FIGS.

[0120] The connecting part 281 is configured to form a third accommodating cavity 282 with an opening. The opening of the third accommodating cavity 282 faces the convex structure 242, and part of the convex structure 242 is clamped in the third accommodating cavity 282 through the opening.

When both of the two first door bodies 201 are in the closed state, the first elastic damping members 285 provided on the two first door bodies 201 both elastically abut against the front wall 130 below the refrigerating compartment 111 at the upper part of the cabinet 10 to buffer the closing force of the first door body 201, reduce the vibration amplitude when the first door body 201 closes, and make the first door body 201 closer more smoothly.

[0126] The door body 20 can include a second door body 202, and the second door body 202 is correspondingly arranged with the refrigerating compartment 111 located at the lower part of the cabinet 10. There can be two second door bodies 202 correspondingly arranged with the refrigerating compartment 111 located at the lower part of the cabinet 10.

[0127] Reference Figure 1 , Figure 8 and Figure 9, the elastic damping member 280 may include a second elastic damping member 286, and the second elastic damping member 286 is disposed on the convex structure 242 on the second door body 202. When both second door bodies 202 are in the closed state, the second elastic damping members 286 disposed on the two second door bodies 202 are both elastically abutted against the front wall 130 of the refrigerator below the refrigerating compartment 111 at the lower part of the cabinet 10, so as to buffer the closing force of the second door body 202, reduce the vibration amplitude when the second door body 202 is closed, and make the second door body 202 closer smoothly when closed.

[0128] Reference Figure 1 , the refrigerator further includes a magnetic sensor component 30. The magnetic sensor component 30 is used to detect the magnetic field strength at the magnetic sensor component 30. Exemplarily, the magnetic sensor component 30 may be a Hall sensor or a magnetoresistive sensor, etc.

[0129] The magnetic sensor component 30 may be disposed on the front wall 130 between the refrigerating compartment 111 at the upper part of the cabinet 10 and the refrigerating compartment 111 at the lower part of the cabinet 10.

[0130] Exemplarily, reference Figure 10 and Figure 11 , the magnetic sensor component 30 may include a mounting box 310, a magnetic sensor 320 and a connecting wire harness 330.

[0131] The mounting box 310 includes a box body 311, a first stop member 314 and a second stop member 315.

[0132] An installation opening 131 may be formed on the front wall 130 between the refrigerating compartment 111 at the upper part of the cabinet 10 and the refrigerating compartment 111 at the lower part of the cabinet 10. The box body 311 passes through the installation opening 131, and a wire harness opening 312 is formed on the side wall of the box body 311, and the wire harness opening 312 is located inside the front wall 130.

[0133] The first stop member 314 may be a stop plate (reference Figure 11 ), or a stop block, etc. The first stop member 314 is located outside the front wall 130 and is disposed at one end of the box body 311 facing away from the front wall 130, and the periphery of the first stop member 314 extends to the outside of the box body 311.

[0134] Reference Figure 11 , in the implementation manner where the first stop member 314 is a stop plate, the plate surface of the first stop member 314 may be attached to the front wall 130, and the thickness of the first stop member 314 is small, reducing the thickness of the first stop member 314 protruding from the front side of the front wall 130 and reducing the influence of the magnetic sensor component 30 on the opening and closing of the refrigerator door.

[0135] The second stop member 315 may be a stop block (reference Figure 11) or a stop ring, etc. The second stop member 315 is disposed on the circumferential side of the box body 311. The second stop member 315 is located inside the front wall 130 of the box. The front wall 130 of the box is clamped between the first stop member 314 and the second stop member 315 to dispose the mounting box 310 on the front wall 130 of the box.

[0136] One side of the second stop member 315 facing away from the first stop member 314 has a guiding inclined surface 316. The distance between the guiding inclined surface 316 and the box body 311 gradually increases from the end far away from the first stop member 314 to the end close to the first stop member 314. When the mounting box 310 is passed through the mounting opening 131, the front wall 130 of the box at the edge of the mounting opening 131 slides relative to the mounting box 310 along the guiding inclined surface 316 and presses the mounting box 310 towards the inside of the mounting box 310. The second stop member 315 undergoes an appropriate displacement towards the inside of the box body 311, and the front wall 130 of the box slides into the space between the first stop member 314 and the second stop member 315. After the front wall 130 of the box slides into the space between the first stop member 314 and the second stop member 315, the second stop member 315 returns to the position before being assembled with the front wall 130 of the box to stop the front wall 130 of the box between the first stop member 314 and the second stop member 315.

[0137] The magnetic sensor 320 is disposed in the box body 311. The box body 311 protects the magnetic sensor 320 and reduces the possibility of the magnetic sensor 320 being damaged by collision.

[0138] The connection wire harness 330 is electrically connected to the magnetic sensor 320, and the connection wire harness 330 is passed through the wire harness opening 312.

[0139] In some possible implementation manners of the embodiments of the present application, with reference to Figure 10 and Figure 11 , one end of the box body 311 facing away from the first stop member 314 may have a placement opening 313, and the placement opening 313 is communicated with the space inside the box body 311. The wire harness opening 312 is communicated with the placement opening 313. The magnetic sensor 320 is disposed in the box body 311 via the placement opening 313.

[0140] The magnetic sensor component 30 may further include a blocking member 317. The blocking member 317 may be a blocking block or a blocking piece, etc. The blocking member 317 blocks the placement opening 313 to limit the magnetic sensor 320 in the box body 311, so that the magnetic sensor 320 is not easily removed from the box body 311.

[0141] In some possible implementation manners of the embodiments of the present application, with reference to Figure 5, in the first door body 201, when the first door body 201 is in the closed state, a first accommodating cavity 243 can be formed on the side of the convex structure 242 facing away from the front wall 130 of the box. The first accommodating cavity 243 is recessed towards the front wall 130 of the box, and the first accommodating cavity 243 communicates with the space inside the first door body 201.

[0142] The refrigerator may include a first magnetic member 40. The first magnetic member 40 has magnetism. The first magnetic member 40 can be a magnet or a magnetic stone, etc.

[0143] The first magnetic member 40 can be disposed on the first plate body 241, and at least a part of the first magnetic member 40 is accommodated in the first accommodating cavity 243.

[0144] Reference Figure 12 and Figure 13 , the first magnetic member 40 and the magnetic sensor component 30 are magnetically engaged. During the opening or closing process of the first door body 201, the distance between the first magnetic member 40 and the magnetic sensor component 30 changes, and the output voltage of the magnetic sensor component 30 changes. Based on the voltage of the magnetic sensor component 30, the current opening angle of the first door body 201 can be calculated, so that the opening and closing states of the first door body 201 can be obtained.

[0145] In the embodiments of the present application, with reference to Figure 5 , this part of the first magnetic member 40 disposed in the first accommodating cavity 243 protrudes from the outer side wall of the first plate body 241. At least a part of the first magnetic member 40 utilizes the space inside the convex structure 242, which not only improves the utilization rate of the space occupied by the convex structure 242, but also makes the first magnetic member 40 closer to the front wall 130 of the box, reduces the distance between the first magnetic member 40 and the magnetic sensor component 30, enhances the magnetic field intensity of the first magnetic member 40 acting on the magnetic sensor component 30, makes the first magnetic member 40 easier to trigger the magnetic sensor 320, and improves the accuracy of the magnetic sensor 320 in detecting the opening and closing states of the first door body 201.

[0146] The first magnetic members 40 on the two first door bodies 201 are both magnetically engaged with the magnetic sensor 320, so that the magnetic sensor 320 can simultaneously detect the magnetic field intensities of the two first magnetic members 40 acting on the magnetic sensor component 30, and the magnetic sensor component 30 respectively determines the opening states of the two first door bodies 201 according to the detected magnetic field intensities.

[0147] In some possible implementation manners of the embodiments of the present application, with reference to Figure 6 、 Figure 7 、 Figure 8 and Figure 9, the lower end cover 240 may further include a second plate body 245. The second plate body 245 may be adjacent to the bottom of the first plate body 241. When the first door body 201 is in the closed state, the second plate body 245 extends in a direction away from the front wall 130 of the box compared to the first plate body 241.

[0148] Reference Figure 5 , in the first door body 201, a second accommodation cavity 246 may be formed on the inner side of one end of the second plate body 245 close to the first plate body 241. The second accommodation cavity 246 communicates with the first accommodation cavity 243. At least part of the first magnetic member 40 is disposed in the first accommodation cavity 243 and the second accommodation cavity 246. On the one hand, the first magnetic member 40 can be fixedly disposed on the lower end cover 240. On the other hand, since the second accommodation cavity 246 is formed on the inner side of the second plate body 245, the thickness of the second plate body 245 corresponding to the second accommodation cavity 246 is reduced. When the first magnetic member 40 is disposed in the second accommodation cavity 246, the shielding thickness of the second plate body 245 for the first magnetic member 40 is reduced, thereby reducing the attenuation of the magnetic force of the first magnetic member 40 during the transmission to the magnetic sensor 320, making the first magnetic member 40 easier to trigger the magnetic sensor 320, and improving the accuracy of the magnetic sensor 320 in detecting the opening and closing state of the first door body 201.

[0149] In some possible implementation manners of the embodiments of the present application, reference Figure 5 , Figure 6 , Figure 7 , Figure 12 and Figure 13 , a first through hole 247 is formed in the second plate body 245 corresponding to the second accommodation cavity 246, and the first through hole 247 communicates with the second accommodation cavity 246. The first through hole 247 corresponds to a part of the first magnetic member 40.

[0150] It can be understood that one or at least two first through holes 247 may be provided.

[0151] By forming the first through hole 247 in the second plate body 245, the shielding of the second plate body 245 for the first magnetic member 40 can be further reduced, the attenuation of the magnetic force of the first magnetic member 40 during the transmission to the magnetic sensor 320 is reduced, the first magnetic member 40 is made easier to trigger the magnetic sensor 320, and the accuracy of the magnetic sensor 320 in detecting the opening and closing state of the first door body 201 is improved.

[0152] In some possible implementation manners of the embodiments of the present application, reference Figure 5 , Figure 6 , Figure 7 , Figure 12 and Figure 13, and on the outer side of the second plate body 245 corresponding to the second accommodation cavity 246, a reinforcing protrusion 248 can be formed, and the reinforcing protrusion 248 protrudes in a direction away from the second accommodation cavity 246.

[0153] Exemplarily, the reinforcing protrusion 248 can be a bump or a boss provided on the outer side of the second plate body 245, etc.

[0154] Since the thickness of the second plate body 245 is small, the depth of the second accommodation cavity 246 formed on the inner side of the second plate body 245 is small. The depth of the second accommodation cavity 246 refers to the length of the second accommodation cavity 246 along the thickness direction of the second plate body 245.

[0155] After the reinforcing protrusion 248 is provided on the outer side of the second plate body 245 corresponding to the second accommodation cavity 246, the total thickness of the second plate body 245 and the reinforcing protrusion 248 is increased compared to the thickness of the second plate body 245. Therefore, the depth of the second accommodation cavity 246 that can be formed on the inner side of the second plate body 245 is increased, improving the fixing firmness of the first magnetic member 40 by the second accommodation cavity 246.

[0156] In some possible implementation manners of the embodiments of the present application, referring to Figure 1 , the door frame 220 includes a second door frame 222, and the second door frame 222 is located on the outer periphery of the second door body 202. In the second door body 202, the upper end cover 230 of the second door frame 222 is close to the lower end cover 240 of the first door body 201.

[0157] Referring to Figure 5 and Figure 14 , the upper end cover 230 of the second door body 202 has a third plate body 231 and a fourth plate body 233. When the second door body 202 is in the closed state, the third plate body 231 faces the front wall 130 of the box, the fourth plate body 233 is adjacent to the top end of the third plate body 231, and the fourth plate body 233 extends in a direction away from the front wall 130 of the box compared to the third plate body 231. On the side of the fourth plate body 233 facing the inside of the second door body 202, a fourth accommodation cavity 234 can be formed. Exemplarily, the fourth accommodation cavity 234 can be surrounded by a surrounding plate 235 provided on the inner side of the fourth plate body 233. The fourth accommodation cavity 234 is close to the open end 204 of the second door body 202. The refrigerator can further include a second magnetic member 50, and the second magnetic member 50 is disposed in the fourth accommodation cavity 234. The second magnetic member 50 cooperates with the magnetic sensor component 30 so that the magnetic sensor component 30 can detect the magnetic field strength exerted on the magnetic sensor component 30 by the second magnetic member 50.

[0158] The magnetic sensor component 30 is disposed on the front box wall 130 between the refrigerating compartment 111 located at the upper part of the box body 10 and the refrigerating compartment 111 located at the lower part of the box body 10. The magnetic sensor component 30 can be magnetically coupled with the first magnetic members 40 respectively disposed on the two first door bodies 201 and the second magnetic members 50 respectively disposed on the two second door bodies 202 to detect the opening states of the two first door bodies 201 and the two second door bodies 202.

[0159] In some possible implementation manners of the embodiments of the present application, with reference to Figure 5 and Figure 14 , the third plate body 231 may be provided with a second through hole 232 communicating with the fourth accommodating cavity 234. The second through hole 232 corresponds to a part of the second magnetic member 50.

[0160] It can be understood that one or at least two second through holes 232 may be provided.

[0161] By providing the second through hole 232 on the third plate body 231, the shielding of the third plate body 231 from the second magnetic member 50 can be reduced, the attenuation of the magnetic force of the second magnetic member 50 during the transmission to the magnetic sensor 320 can be reduced, the second magnetic member 50 can be more easily triggered by the magnetic sensor 320, and the accuracy of the magnetic sensor 320 in detecting the opening and closing states of the second door body 202 is improved.
