[0002] Existing refrigerators usually have one door for each storage compartment. However, a large-capacity refrigerator designed for storing large items has a large storage compartment length and width. If only one door is provided, the door will be too heavy and difficult for users to open.

[0003] To solve this problem, multiple doors are usually set up to reduce the weight of a single door for easier opening. A crossbeam is set between two adjacent doors. The crossbeam is placed at the cabinet opening to support the weight of the door and seal the gap between the two doors to prevent cold air from leaking.

[0004] When taking out large items, you need to open the doors on both sides of the beam and then remove the beam. After taking out and placing, you need to install the beam first and then close the door, which is cumbersome. If you forget to install the beam, it will not affect the closing of the door, but it will cause cold leakage and increase energy consumption; it may even cause the indoor temperature of the storage room to rise abnormally, causing the stored items to deteriorate and causing economic losses.

DETAILED DESCRIPTION

[0027] See also Figure 1 The present invention provides a multi-door refrigerator with a detachable crossbeam, comprising a cabinet 1, wherein a storage compartment 11 is provided in the cabinet 1; at least two doors 2 are rotatably connected to the cabinet 1;

[0028] The joint of the two doors 2 is provided with a crossbeam 3 that can be movably mounted on the cabinet 1; Figure 6 A positioning shaft 31 is fixedly arranged at both ends of the crossbeam 3, and a positioning groove 12 for carrying the positioning shaft 31 is correspondingly arranged on the cabinet 1; a magnetic column 34 for adsorbing the door body 2 is arranged on the crossbeam 3;

[0029] See also Figure 2 When the door bodies 2 on both sides of the beam 3 are closed, the two door bodies 2 are pressed on the beam 3 at the same time; the joint of the two door bodies 2 is sealed to prevent cold leakage from there.

[0030] When any one of the door bodies 2 on both sides of the beam 3 is opened separately, the other closed door body 2 is pressed on the beam 3; the gravity of the door body 2 is much greater than the magnetic attraction between the magnetic column 34 of the beam 3 and the door body 2, so when the door body 2 on the other side is opened, it can be separated from the beam 3, so that the beam 3 remains mounted on the cabinet body 1.

[0031] When the doors 2 on both sides of the beam 3 are opened, the door 2 opened later lifts the beam 3, and the positioning shaft 31 of the beam 3 is disengaged from the positioning groove 12 of the cabinet 1, so that the opening position of the cabinet 1 is unobstructed and large-volume items can be taken out.

[0032] Afterwards, the cross beam 3 is closed along with the door body 2 , and the positioning shaft 31 enters the positioning groove 12 again, so that the cross beam 3 returns to its original state.

[0033] The present invention uses magnetic attraction to allow the crossbeam 3 to be separated from the cabinet body 1 as the door body 2 is opened; there is no need to disassemble and install it separately, which simplifies the operation and avoids the problem of missing installation after disassembly. There is no connecting part between the crossbeam 3 and the door body 2, the structure is simple, and it is easy to replace.

[0034] As an embodiment, the magnetic poles 34 are arranged in two rows, and the two rows of magnetic poles 34 are symmetrically arranged at the junction of the top surface and the side surface of the beam 3; the magnetic poles 34 are cylindrical; the central axes of each row of magnetic poles 34 are located on the same straight line parallel to the length direction of the beam 3;

[0035] Each row of magnetic posts 34 is attracted to the door body 2 on the corresponding side; the cylindrical surface of each magnetic post 34 is attracted to the door body 2, and the attracted positions are all located on the same virtual magnetic line; see Figure 4 The door body 2 is also provided with a magnetic strip 24 for engaging with the side of the crossbeam 3;

[0036] Since the magnetic connection between the beam 3 and the door body 2 is a linear connection, when the beam 3 opens with the door body 2, under the action of its own gravity, the beam 3 can swing outward relative to the door body 2; when the side of the beam 3 swings close to or abuts the door body 2, it is adsorbed on the door body 2 under the action of the magnetic strip 24; at this time, the beam 3 is fixed on the door body 2.

[0037] See also Figure 5 , both side walls of the positioning groove 12 are provided with an introduction surface 121; when the beam 3 is closed with the door body 2, the positioning shaft 31 enters the positioning groove 12 along the introduction surface 121; when the squeezing force of the introduction surface 121 on the positioning shaft 31 is greater than the magnetic attraction force of the magnetic strip 24 on the side of the beam 3, the two are separated; at this time, the beam 3 rotates in the opposite direction until it returns to its original state, and the positioning shaft 31 is re-mounted on the two positioning grooves 12 of the cabinet body 1.

[0038] Furthermore, the top surface and the side surface of the cross beam 3 are connected by an arc-shaped transition structure, and the central axis of the arc structure coincides with the central axis of the magnetic column 34. When the door body 2 is opened or closed, the arc surface of the cross beam 3 is adsorbed on the door body 2 and rolls along the door body 2 to realize the rotation of the cross beam 3. The rotation process of the cross beam 3 is smooth, and during the rotation process, the magnetic attraction force is stable and unchanged, and it is not easy to fall off.

[0039] The crossbeam 3 of this embodiment can be fixed on the door body 2 when the door body 2 is opened. Its edge parts are all located within the range of the door body 2. When closed, the crossbeam 3 allows the positioning shaft 31 to enter the positioning groove 12 in a vertical posture. This process is not limited by the opening and closing state of the other side door body 2. Therefore, after both door bodies 2 are opened, their closing order is not limited. The user can arbitrarily close one of the door bodies 2 first, or close both door bodies 2 at the same time, which will not affect the resetting of the crossbeam 3, thereby facilitating the use of the refrigerator.

[0040] As an embodiment, a partition block 13 is provided in the positioning groove 12; two introduction surfaces 121 are symmetrically arranged on both sides of the partition block 13; a slot for the positioning shaft 31 to enter and exit is formed between the partition block 13 and the introduction surface 121. When the crossbeam 3 is magnetically attracted to one side of the door body 2 and moves, the positioning shaft 31 can enter / enter the positioning groove 12 from the slot on the corresponding side, and the entry and exit posture is stable.

[0041] Furthermore, the positioning shaft 31 is arc-shaped, and the dividing block 13 has an arc surface that cooperates with the positioning shaft 31; when the beam 3 enters / exits the positioning groove 12, the positioning shaft 31 rotates relative to the dividing block 13 in a surface contact manner, so that the beam 3 is stable in the exit / entry posture, ensuring accurate reset every time.

[0042] See also Figure 3 and Figure 4 As an embodiment, the door body 2 is further provided with an inner lining 22 protruding toward one side of the storage compartment 11; the inner lining 22 forms a limiting surface on the side close to the cross beam 3; after the cross beam 3 is opened and turned into position with the door body 2, it is blocked by the limiting surface to prevent it from moving outward. When the door body 2 is closed, the cross beam 3 can be accurately reset.

[0043] Furthermore, an adsorption plate 23 for generating magnetic attraction with the magnetic column 34 is provided in the door body 2; the adsorption plate 23 is made of magnetic conductive material and can generate a large magnetic attraction with the magnetic column 34 to prevent the crossbeam 3 from falling off during the opening / closing process of the door body 2.

[0044] The magnetic pole 34 and the magnetic strip 24 are preferably made of strong magnetic materials, such as neodymium magnets, to generate strong magnetic attraction.

[0045] Optionally, the magnetic strip 24 and the adsorption plate 23 are arranged on the inner surface of the lining 22, so that the outer surface of the door body 2 is neat and beautiful.

[0046] See also Figure 6 The crossbeam 3 includes a shell cover 32 and a base body 33 buckled in the shell cover 32; two rows of magnetic posts 34 are embedded in the base body 33;

[0047] Furthermore, fixing members 35 are provided on both side walls of the base body 33; the fixing members 35 are configured to generate a strong magnetic attraction force with the magnetic attraction strip 24, so that the crossbeam 3 can be smoothly adsorbed on the door body 2 after rotation;

[0048] Preferably, the fixing member 35 has two fixing plates at an angle of 90°, and the two fixing plates are respectively embedded on the top surface and the side surface of the base body 33 , thereby improving its stability on the base body 33 .

[0049] More preferably, each row of magnetic poles 34 are arranged at equal intervals, and a fixing member 35 is provided between two adjacent magnetic poles 34, so that the magnetic attraction force on the beam 3 in the length direction is uniform.

[0050] The shell cover 32 and the base body 33 of the present invention are both made of light materials, which reduces the weight of the cross beam 3 and makes it difficult to fall off. For example, the shell cover 32 and the base body 33 are both made of plastic material, which has high strength and light weight.

[0051] Optionally, a handle 21 is fixedly provided on the door body 2 of the present invention to facilitate the operation of opening / closing the door body 2.

[0052] As a method, according to the volume of the storage compartment and the length of the cabinet 1, the door body 2 of the present invention can be multiple, and a beam 3 is set at the joint of the two door bodies 2; when any two adjacent door bodies 2 are opened, the beam 3 between the two acts in the above-mentioned manner.

[0053] In summary, the present invention provides a multi-door refrigerator with a detachable crossbeam, which can be separated from the cabinet body by magnetic attraction as the door body is opened; there is no need to disassemble and install it separately, which simplifies the operation and avoids the problem of missing installation after disassembly. There is no connecting part between the crossbeam and the door body, the structure is simple, and it is easy to replace.

[0054] Of course, the present invention may have many other embodiments.
