[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] like Figure 1 and Figure 2 As shown, the present invention provides a door lock structure, comprising:

[0035] The door lock includes a door hook 12 and a rotatable latch 13. The latch 13 is hooked to the door hook 12, locking the door and disengaging from the door hook 12, unlocking the door. The position detection component 2 detects the position of the latch 13 to detect whether the latch 13 has completed locking or unlocking.

[0036] In an embodiment of the present invention, the door lock structure includes a door hook 12 fixed to the machine door, and a lock body fixed to the washing drum or the supporting shell. The lock body includes a latch 13. When the machine door is closed, the hook hole of the door hook 12 hooks with the latch 13 to lock the machine door.

[0037] The washing machine includes a supporting outer shell, an outer shell door provided on the supporting outer shell, a washing drum provided inside the supporting outer shell, and a washing drum door provided on the washing drum. For example, a door hook 12 can be provided on the washing drum door and a lock body can be provided on the washing drum, or a door hook 12 can be provided on the washing machine door and a lock body can be provided on the supporting outer shell.

[0038] Position detection components can be electromagnetic position detection components, laser position detection components, infrared position detection components, acoustic position detection components, electric field position detection components, etc.

[0039] Specifically, the position detection component 2 includes a detected terminal and a position sensor. The detected terminal is a magnet 21, and the position sensor is a Hall sensor 22.

[0040] The latch 13 can hook the door hook 12 when rotating in one direction, and can disengage from the door hook 12 when moving in the opposite direction. The lock body also includes a limiting block 14 that restricts the movement of the latch 13. When the door hook 12 is hooked by the latch 13, the limiting block 14 abuts against the latch 13, keeping the latch 13 stationary, thus ensuring that the latch 13 can continuously and stably lock the door hook 12. When unlocking is required, the limiting block 14 can be moved to release the restriction on the latch 13, causing the latch 13 to rotate in the opposite direction, thereby separating the locking structure from the door hook 12 and unlocking the door.

[0041] The lock body includes a first outer shell 11, and a bolt 13 is rotatably disposed in the first outer shell 11. Specifically, a support rod is mounted in the first outer shell 11, with both ends of the support rod fixed to the bottom of the first outer shell 11 of the lock body. The rotatable bolt 13 is sleeved on the support rod, and the bolt 13 is fixed inside the outer shell by the support of the support rod.

[0042] The limiting block 14 has an "L"-shaped structure. When the locking device is not in motion, the latch 13 is embedded in the gap of the "L"-shaped structure in the limiting structure. The "L"-shaped structure consists of a vertical limiting post and a horizontal base perpendicular to it. When the latch 13 is embedded in the gap of the "L"-shaped structure, the end face of the latch 13 perpendicular to the rotation axis abuts against the first limiting surface on the limiting post. That is, at the beginning of the movement, the latch 13 is locked and limited by the limiting block 14. A torsion spring 15 is provided between the end of the limiting block 14 perpendicular to the rotation axis of the latch 13 and the first outer shell 11. When stationary at the beginning of the movement, the limiting block 14 compresses the torsion spring 15. When the latch 13 is stationary, the limiting block 14 is restricted by the stationary latch 13, and the limiting block 14 compresses the torsion spring 15. When the door hook 12 contacts and triggers the latch 13 to rotate, the latch 13 rotates, releasing the movement restriction on the limiting block 14. Therefore, the limiting block 14 begins to move under the action of the torsion spring 15. When unlocking is required, simply activating the limiting block 14 releases the restriction on the latch 13. The latch 13 rotates in the opposite direction under the action of the torsion spring 15, causing the latch 13 to disengage from the door hook 12.

[0043] When the door is locked, the torsion spring 15 on the limit block 14 is compressed and stored. When the door needs to be unlocked, other structures push the part of the limit block 14 outside the housing, and the limit block 14 undergoes an unlocking movement under the action of the torsion spring 15.

[0044] In embodiments of the present invention, a positioning lock 3 is also included, which triggers the bolt 13 to disengage from the door hook 12. The first part of the position detection component 2, namely the magnet, is located on the door lock and can rotate with the bolt. The second part of the detection device, namely the Hall sensor, is located on the positioning lock. The second part detects the position change of the first part.

[0045] In an embodiment of the present invention, the positioning lock 3 includes a second outer shell 31, and an opening rod 32 is provided inside the second outer shell 31. The opening rod 32 extends from one side of the second outer shell 31 to trigger the locking tongue 13 to disengage from the door hook 12. A Hall sensor 22 is provided on the side of the opening rod 32 extending from the second outer shell 31. The opening rod 32 is positioned towards the limiting block 14. When the door lock is unlocked, the opening rod 32 moves outward from inside the second outer shell 31 to trigger the limiting block 14 to move, and the locking tongue 13 disengages from the door hook 12, thereby unlocking the door lock. When the door lock is locked, the opening rod 32 is pushed by the door hook 12, and the locking tongue 13 hooks with the door hook 12. The opening rod 32 moves into the second outer shell 31, thereby locking the door lock.

[0046] Specifically, the first part is a magnet 21, and the second part is a Hall sensor 22. The magnet 21 on the door lock is positioned facing the Hall sensor 22 on the positioning lock 3. The magnet 21 rotates with the lock tongue 13 and the magnetic field changes. The Hall sensor 22 detects the change in the magnetic field of the magnet 21.

[0047] For example, when the latch 13 is in the unlocked position, the magnet 21 is in the initial position, and the Hall sensor 22 detects that the magnetic field of the magnet 21 is the first magnetic field. When the latch 13 reaches the locked position, as the latch 13 switches from the unlocked position to the locked position, the latch 13 rotates under the push of the door hook 12. During the rotation of the latch 13, the magnet 21 rotates. Therefore, when the latch 13 reaches the locked position, the position of the magnetic field changes, which causes the magnetic field of the magnet 21 to change. The Hall sensor 22 detects that the magnetic field of the magnet 21 is the second magnetic field. By judging the position of the magnet 21 through the different magnetic fields detected by the Hall sensor 22, it is possible to determine whether the latch 13 is in the locked or unlocked position.

[0048] like Figure 2 As shown, in an embodiment of the present invention, the door lock further includes a first outer shell 11 with a latch 13 inside. The hook hole of the door hook 12 can be inserted into the first outer shell 11 and hooked with the latch 13. A magnet 21 is rotatably provided on the first outer shell 11. At least part of the magnet 21 is located on the outer periphery of the latch 13 in the direction of rotation and can abut against the latch 13. The rotation axis of the magnet 21 is perpendicular to the rotation axis of the latch 13.

[0049] In an embodiment of the present invention, when the door is closed, the door hook 12 rotates with the door, and the hook hole of the door hook 12 is inserted into the first outer shell 11 and hooked with the lock tongue 13. At least part of the magnet 21 is provided on the outer periphery of the lock tongue 13 in the direction of rotation, so that the magnet 21 can abut against the lock tongue 13 during the rotation of the lock tongue 13, thereby changing position as the lock tongue 13 rotates.

[0050] The rotation axis of magnet 21 is perpendicular to the rotation axis of latch 13, such as... Figure 1 As shown, if the rotation axis of the latch 13 extends in the left-right direction, then the rotation axis of the magnet 21 extends in the front-back direction, thereby realizing the front-back rotation of the latch 13 and the left-right rotation of the magnet 21.

[0051] Furthermore, a rotating member 4 is rotatably provided at the bottom of the first outer shell 11. At least part of the rotating member 4 is located on the outer periphery of the bolt 13 in the direction of rotation and can abut against the bolt 13. The first rotation axis 43 of the rotating member 4 is perpendicular to the second rotation axis 16 of the bolt 13. The magnet 21 is provided on one side of the rotating member 4. The magnet 21 rotates with the rotation of the rotating member 4. During the process of the bolt 13 switching from unlocking to locking, the rotating member 4 rotates with the bolt 13, which eventually causes the position of the magnet 21 to change.

[0052] In one embodiment, the magnet has a first working surface and a second working surface. When the door lock is unlocked, the first working surface faces the position sensor and generates a first signal. When the door lock is locked, the second working surface faces the position sensor and generates a second signal different from the first signal. By rotating the magnet, the position sensor selectively senses either the first or the second working surface. When unlocking, the door hook disengages from the latch, the first working surface faces the position sensor, and the position sensor senses the first working surface of the magnet and generates the first signal. When locking, the door hook engages with the latch, the second working surface faces the position sensor, and the position sensor senses the second working surface of the magnet and generates the second signal. By comparing the first and second signals, it is determined whether the latch and the door hook are disengaged or engaged, thereby determining whether the door lock is locked or unlocked. Neither the first nor the second signal is zero, or one of the first and second signals is zero. For example, when the first signal is zero, it can be determined that the door lock is unlocked or the door lock is malfunctioning.

[0053] In another embodiment, the rotating member has a first surface and a second surface, and magnets are respectively provided on the first surface and the second surface. When the door lock is unlocked, the first surface faces the position sensor and generates a first signal, and the second surface faces the position sensor when the door lock is locked and generates a second signal different from the first signal. The magnets on the two surfaces of the rotating member generate the first signal and the second signal. Neither the first signal nor the second signal is zero, or one of the first signal and the second signal is zero. For example, when the first signal is zero, it can be determined that the door lock is unlocked or the door lock is malfunctioning.

[0054] like Figure 3As shown, in another embodiment, the magnet 21 has a first working surface 221 and a second working surface, and the rotating member 4 has a first surface 421 and a second surface. The magnet 21 is disposed on the first surface 421. When the door lock is unlocked, the first working surface 221 and the first surface 421 face the position sensor and generate a first signal. When the door lock is locked, the second working surface and the second surface face the position sensor and generate a second signal different from the first signal. By rotating the magnet 21, the position sensor selectively senses the first working surface 221 and the second working surface. When unlocking, the door hook 12 disengages from the latch 13, and the first working surface 221 and the first surface 421 face the position sensor. The position sensor senses the first working surface 221 of the magnet 21 and generates a first signal. When locked, the door hook 12 is hooked with the bolt 13. The second working surface and the second surface face the position sensor. The position sensor senses the second working surface of the magnet and generates a second signal. By comparing the first signal and the second signal, it is determined whether the bolt and the door hook are disengaged or hooked, thereby determining whether the door lock is locked or unlocked. Neither the first signal nor the second signal is zero, or one of the first signal and the second signal is zero. For example, when the first signal is zero, it can be determined that the door lock is unlocked or the door lock is malfunctioning.

[0055] The area of ​​the first working surface is different from that of the second working surface, which makes the magnetic flux of the first working surface different from that of the second working surface.

[0056] Specifically, the magnet 21 and the rotating component 4 are both cuboids. The first working surface 221 and the second working surface are located on two adjacent sides of the magnet 21, respectively. The first surface 421 is adjacent to the second surface. The first working surface 221 is located on the first side of the magnet 21, and the second working surface is located on the second side of the magnet 21. The first side and the second side are arranged adjacent to each other. The first surface 421 is the first side of the rotating component, and the second surface is the second side of the rotating component 4. Figure 3 As shown, Figure 3 The second working surface of magnet 21 and the second surface of rotating component 4 are not shown in the figure. Figure 3 The positional relationship of the first working surface 221, the second working surface, the first surface 421 and the second surface is shown when the lock tongue just hooks the door hook and the lock tongue has not yet driven the rotating part to rotate. When switching from unlocking to locking, the rotating part 4 rotates clockwise.

[0057] like Figure 3 As shown, in an embodiment of the present invention, the bottom of the first outer shell 11 protrudes upward to form two support protrusions 5, the two support protrusions 5 are arranged opposite to each other, the two ends of the first rotating shaft 43 are respectively located on the top of the two support protrusions 5, the bottom of the rotating member is provided with a first rotating hole, and the rotating member is rotatably sleeved on the rotating shaft of the rotating member 4 through the first rotating hole.

[0058] In an embodiment of the present invention, the bottom of the first outer shell 11 is provided with two support protrusions 5, which are used to support the rotating member 4, so that there is a gap between the rotating member 4 and the bottom of the outer shell, providing space for the rotation of the rotating member 4.

[0059] One end of the first rotating shaft 43 is located on the top of a support protrusion 5, and the other end is located on the top of another support protrusion 5. The support protrusion 5 supports the rotating component 4.

[0060] The bottom of the rotating component 4 is provided with a first rotating hole. The extension direction of the axis of the first rotating hole is consistent with the extension direction of the first rotating shaft 43. The rotating component is sleeved on the outer peripheral wall of the rotating shaft of the rotating component through the rotating hole, and the rotating component can rotate on the rotating shaft. The axis of the rotating hole coincides with the axis of the rotating component.

[0061] like Figure 3 As shown, in an embodiment of the present invention, the rotating member 4 is stepped and includes a first part 41 and a second part 42. The first part 41 protrudes upward relative to the second part 42. The first part 41 is located on the outer periphery of the locking tongue 13 in the rotation direction and can abut against the locking tongue 13. The magnet 21 is located on one side of the second part 42 opposite to the first part 41. The first rotating hole is located at the bottom of the second part 42.

[0062] In an embodiment of the present invention, the first part 41 is used to abut against the locking tongue 13, and the second part 42 is provided with a first rotating hole. The second part has a first surface 421 and a second surface. Therefore, the first part 41 protrudes upward relative to the second part 42, so that the second part 42 can rotate at a relatively large angle, thereby realizing the switching of the first surface 421 to the second surface so that the second surface faces the position sensor, and the switching of the first working surface 221 to the second working surface so that the second working surface faces the position sensor.

[0063] The bottom of the second part 42 is provided with a first rotating hole. The second part 42 is sleeved on the outside of the first rotating shaft 43 through the first rotating hole, so that the second part 42 can rotate around the axis of the first rotating shaft 43.

[0064] like Figure 3 As shown, in an embodiment of the present invention, the latch 13 is C-shaped, the upper part of the latch 13 can be hooked with the hook hole of the door hook 12, the middle part of the latch 13 is provided with a second rotating hole, the latch 13 is sleeved on the second rotating shaft 16 through the second rotating hole, and the lower part of the latch 13 can abut against the top of the first part 41.

[0065] In an embodiment of the present invention, the latch 13 is C-shaped and has a first bent portion 131 at the upper part of the latch, a second bent portion 132 at the middle part of the latch, and a third bent portion 133 at the lower part of the latch. The second bent portion 132 is provided with a second rotating hole that rotatably cooperates with the second rotating shaft 16. The first bent portion 131 can be hooked with the hook hole of the door hook 12, and the third bent portion can abut against the top of the first part 41.

[0066] like Figure 3 As shown, when the door lock 1 is unlocked, the first working surface 221 and the first surface 421 face the position sensor, ready to lock the door. After the user pushes the door, the door hook 12 pushes the latch 13, the second bending part 132 rotates, and the first bending part 131 of the latch 13 gradually hooks the hook hole of the door hook 12. During the process of the first bending part 131 of the latch 13 gradually hooking the hook hole of the door hook 12, the third bending part 133 pushes down the first part 41 of the rotating part 4, and the second part 42 of the rotating part 4 rotates clockwise to the second working surface and the second surface.

[0067] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
