Description

Technical Field

[0001] This invention relates to the field of washing machine technology, and more specifically to a door lock with a door closing sensor. Background Technology

[0002] Appliance locks play a crucial role in appliances. For safety, the internal working space of an appliance needs to be enclosed during normal operation, especially for appliances like washing machines and dishwashers. If the door is opened arbitrarily during operation, not only can external debris enter and damage the appliance, but people who accidentally touch internal components may also be in danger, causing unnecessary harm. Conversely, if the appliance's lock fails to maintain its position during normal operation, items inside the appliance may fly out, severely impacting product quality and causing significant inconvenience. Therefore, various appliance locks have been designed to enhance safety, ensuring the door automatically locks during operation, preventing it from being opened from the inside, and promptly stopping operation if the door is opened from the outside.

[0003] Authorization announcement number CN107386817B discloses a door lock switch for an electrical appliance. According to the specification and accompanying drawings, the back of the drive block has a guide protrusion that mates with a sliding groove. Therefore, the drive block can drive the unlocking slider to slide, which is used to control the locking hook. However, in this structure, the left and right movement of the unlocking slider is limited by the movement of the drive block. Due to the frequent frictional contact between the drive block and the unlocking slider, it is prone to wear or jamming after prolonged use. Furthermore, in this design, the brake slider can drive the brake top block to slide during sliding. After the door lock is inserted into the lock slot, the brake slider moves to the left, causing the brake top block to move downwards, and the conductive sheet contacts the guide rod, energizing the electric drive structure to achieve door closing sensing. However, if the conductive sheet is deformed due to compression during assembly or transportation, or due to repeated closing and opening, the entire switch sensing may fail, posing a certain risk. Summary of the Invention

[0004] This invention addresses the problems existing in the operation of the aforementioned washing machine door locks by proposing a door lock with a closing sensor. The left and right movement of the first support block causes the first parallel surface or the first inclined surface to contact the bottom of the first lifting slider, which then slides within the first lifting groove. The rising or falling of the first lifting slider energizes or de-energizes the conductive spring and the conductive plate. This design achieves the closing sensor through its structure. The insertion of the locking hook into the first notch on the cam drives the cam to change position. This change in cam position causes the first spring to push the first slider to the right. In other words, the rightward movement of the first slider is achieved by the insertion of the locking hook and the force of the first spring. Therefore, the driving force does not originate from the locking mechanism and has a certain degree of independence. The locking block in the locking mechanism only locks the first slider after it has moved to the designated position. Therefore, there is not much friction between the first slider and the locking block when it moves left and right.

[0007] Preferably, the locking mechanism includes a locking housing, a locking drive block, a second spring, an electric drive body, and a locking block. The locking housing has a second sliding groove inside, and the surface of the second sliding groove has a locking drive block. The locking drive block has a second spring and a second notch inside. The surface of the locking housing has a spring baffle passing through the second notch. One end of the locking drive block is connected to the electric drive body. The surface of the locking housing also has a locking notch. The locking block is slidably connected inside the locking notch. The bottom of the locking block is adapted to the locking hole groove. The sidewall of the locking drive block is connected to the locking block through a guide structure. When the locking drive block slides, the locking block can move up and down.

[0008] Preferably, the electric drive body consists of a coil and a pull rod. The pull rod is located inside the coil. When the coil is energized, the pull rod moves downward. One end of the coil is provided with a conductive rod, and the end of the conductive rod is provided with a conductive spring. The end of the first lifting slider is provided with a first groove. The maximum length of the first groove is less than the diameter of the conductive spring. The conductive spring is located on the surface of the first groove. A conductive plate is located inside the first groove. The conductive plate is connected to an external power source. The surface of the locking housing is also provided with a first lifting groove. The first lifting slider is slidably connected inside the first lifting groove. When the first lifting slider descends, the conductive spring and the conductive plate are energized.

[0009] Preferably, the guide structure consists of a first rib and a second rib. The second rib includes a second parallel surface and a second inclined surface. The second inclined surface and the bottom of the first rib form a guide groove. A guide cylinder is provided on one side of the upper locking block. The guide cylinder slides in the guide groove or the second parallel surface.

[0010] Preferably, the support housing is further provided with a third sliding groove, and a third spring and a second slider are slidably connected inside the third sliding groove. One end of the second slider is connected to the third spring, and the other end of the second slider is stuck on the side wall of the cam. The surface of the second slider is provided with a limiting boss. When the cam is not rotating, the limiting boss can restrict the operation of the locking mechanism.

[0011] Preferably, the surface of the locking housing is provided with a limiting groove, the limiting boss passes through the limiting groove, and the bottom of the locking drive block is provided with a drive block boss, the limiting boss being able to restrict the movement of the drive block boss.

[0012] Preferably, the surface of the second slider is provided with a third plane and a fourth plane of different heights, and the surface of the locking housing is also provided with a second lifting groove. The second lifting slider is provided inside the second lifting groove. A metal plate is connected to the top of the second lifting slider. The metal plate has a certain toughness. The bottom of the second lifting slider is attached to the third plane or the fourth plane. A signal output plate is provided on one side of the second lifting groove. When the bottom of the second lifting slider is attached to the third plane, the signal output plate and the metal plate do not contact each other.

[0013] Preferably, the second slider has an inclined boss at one end near the cam, and the end of the cam has a boss groove. When the cam is not rotating, the inclined boss is locked inside the boss groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The left and right movement of the first support block causes the first parallel surface or the first inclined surface to fit against the bottom of the first lifting slider, so that the first lifting slider will slide in the first lifting groove. The rise or fall of the first lifting slider can keep the conductive spring and the conductive plate in a state of being energized or de-energized. This scheme completes the door opening or closing sensing through structure. The conductive spring is not easy to deform. Under the elastic action of the conductive spring and the limiting action of the first groove, the entire door closing sensing is not easy to fail and can be used for a long time; 2. The insertion of the lock hook into the first notch on the cam will drive the cam to change position. The change in the position of the cam causes the first spring to push the first slider to move to the right. That is to say, the rightward movement of the first slider is achieved by the insertion of the lock hook and the force of the first spring. Therefore, the driving force does not come from the locking mechanism and has a certain degree of independence. Moreover, this independence structure is simple and not easy to fail, which is beneficial for long-term use. 3. The locking block in the locking mechanism only locks after the first slider moves to the designated position. Therefore, there is not much friction between the first slider and the locking block when the first slider moves left and right, which is also conducive to stable use over a long period of time. 4. When the electric drive structure malfunctions, the locking block cannot retract. In this case, the first slider will continue to be stuck in the cam in the hook inlet, and the hook will not be easy to pull out. If the user forcibly pulls out the hook, the reaction force of the third spring will push the second slider to the right. During the sliding process of the second slider, the bottom of the second lifting slider gradually separates from the third plane until it is in contact with the second plane. The second lifting slider slides upward inside the second lifting slide groove. The second lifting slider will pull the metal plate upward. The metal plate and the signal output board will be disconnected. At this time, the signal output board will transmit a signal to the washing machine that the door hook has disengaged, and the washing machine will stop working. This design will not affect the control of stopping the washing machine even if the electric drive structure fails. Attached Figure Description

[0025] The present invention will be further described below with reference to the embodiments illustrated in the accompanying drawings:

[0026] like Figures 1 to 9As shown, a door lock with a closing sensor includes a supporting housing 1, a locking mechanism 4 disposed on the surface of the supporting housing 1, a rotatable cam 11 and a lock hook inlet 12 disposed inside the supporting housing 1, and a first slide groove 13 provided inside the supporting housing 1. A first slider 2 is slidably connected to the first slide groove 13. It should be noted that the top right side of the first slider 2 is an inclined end face, so the first slider 2 slides inclined to the lower right in the first slide groove 13. The inclined end face has a guiding function when sliding in the first slide groove 13, making it less prone to jamming. A first lifting slider 24 is provided inside the locking mechanism 4. The rising or falling of the first lifting slider 24 is used to control the power state of the locking mechanism 4. The surface of the first slider 2 can be opened. A first support block 22 is mounted on the sliding part of the first slider 24. The first support block 22 has a first parallel surface 221 and a first inclined surface 222. The end of the first lifting slider 24 is attached to the first support block 22. The sliding of the first support block 22 causes the end of the first lifting slider 24 to be attached to the first parallel surface 221 or the first inclined surface 222, thereby achieving lifting. To prevent jamming during the attachment process, the end of the first lifting slider 24 should have a rounded corner or chamfer. The surface of the first slider 2 is provided with a locking groove 21. The first groove 13 is provided with a first spring 3. One end of the first slider 2 is connected to the first spring 3, and the other end of the first slider 2 is attached to the side wall of the cam 11. The side wall of the cam 11 is provided with... The first socket 111, the locking mechanism 4 includes a locking housing 41, a locking drive block 43, a second spring 44, an electric drive body 47, and a locking block 49. The locking housing 41 has a second sliding groove 42 inside, and the surface of the second sliding groove 42 has a locking drive block 43. The locking drive block 43 has a second spring 44 and a second notch 45 inside. The surface of the locking housing 41 has a spring baffle 46 passing through the second notch 45. One end of the locking drive block 43 is connected to the electric drive body 47. The surface of the locking housing 41 also has a locking notch 48, and the locking block 49 is slidably connected inside the locking notch 48. The bottom of the locking block 49 is adapted to the locking hole slot 21. The locking drive block 43... The sidewall is connected to the locking block 49 via a guide structure 40. When the locking drive block 43 slides, the locking block 49 can move up and down. After the external locking hook is inserted into the first insertion port 111, the cam 11 rotates. Thus, the first slider 2 is ejected to the lower right corner under the reaction force of the first spring 3 until the first slider 2 slides into the locking hook inlet 12. At this time, the first slider 2 is no longer attached to the sidewall of the cam 11. If the first slider 2 is locked at this time, it will interfere with the cam 11, restricting the rotation of the cam 11, and the external locking hook cannot be easily pulled out. Therefore, the up and down movement of the locking block 49 can lock or unlock the first slider 2. Of course, if the first slider 2 is not locked by the locking block 49, the cam 11 can still rotate normally.The door hook can be pulled out normally.

[0027] In this embodiment, the electric drive body 47 consists of a coil 471 and a pull rod 472. The pull rod 472 is disposed inside the coil 471. When the coil 471 is energized, the pull rod 472 moves downward. One end of the coil 471 is provided with a conductive rod 473, and the end of the conductive rod 473 is provided with a conductive spring 474. The end of the first lifting slider 24 is provided with a first groove 241. The maximum length of the first groove 241 is less than the diameter of the conductive spring 474. The conductive spring 474 is disposed on the surface of the first groove 241. A conductive plate 8 is disposed inside the first groove 241. The conductive plate 8 is connected to an external power source. The surface of the locking housing 41 is also... A first lifting slide 410 is provided, and the first lifting slider 24 is slidably connected inside the first lifting slide 410. The sliding of the first slider 2 can drive the first support block 22 to slide on the guide rib 18. Whenever the first slider 2 moves to the lower right under the reaction force of the first spring 3, it will drive the first support block 22 to move to the right on the guide rib 18. During the movement, the first inclined surface 222 gradually fits against the bottom of the first lifting slider 24, so the first lifting slider 24 will slide down the first lifting slide 410. After the first lifting slider 24 descends, the conductive spring 474 can be energized with the conductive plate 8. At this time, the door closing sensing is completed through the structure.

[0028] In this embodiment, the guide structure 40 comprises a first rib 401 and a second rib 402. The length of the first rib 401 is less than that of the second rib 402. The second rib 402 includes a second parallel surface 403 and a second inclined surface 404. The second inclined surface 404 forms a guide groove with the bottom of the first rib 401. A guide cylinder 491 is provided on one side of the locking block 49. The guide cylinder 491 slides on the guide groove or the second parallel surface 403. Specifically, the locking drive block 43 has a locking slot and an unlocking slot relative to the locking housing 41. When the door hook is not inserted, the locking drive block 43 is located in the unlocking slot. The moving block 43 switches between different slots by sliding once. Whenever the locking drive block 43 is in the locking slot, the external power supply energizes the coil 471 with a pulse signal, and the pull rod 472 pulls the locking drive block 43 downward once. Under the elastic action of the second spring 44 being squeezed, it is pushed to the position of the unlocking slot. The guide cylinder 491 slides through the second inclined surface 404 under the guidance of the guide groove until it slides on the second parallel surface 403. Therefore, when the locking drive block 43 slides through the middle, the locking block 49 moves upward inside the locking notch 48. At this time, the locking block 49 cannot lock the first slider 2.

[0029] In this embodiment, the support housing 1 is further provided with a third slide groove 14. A third spring 15 and a second slider 16 are slidably connected inside the third slide groove 14. One end of the second slider 16 is connected to the third spring 15, and the other end of the second slider 16 is engaged with the side wall of the cam 11. Specifically, the end of the second slider 16 near the cam 11 has an inclined boss 164, and the end of the cam 11 has a boss groove 17. When the cam 11 is not rotating, the inclined boss 164 is engaged inside the boss groove 17. The surface of the second slider 16 has a limiting boss 161, and the surface of the locking housing 41 has a limiting groove 411 through which the limiting boss 161 passes. The bottom of the locking drive block 43 has a drive block boss 431. When the lock hook is not inserted, the limiting boss 161 can restrict the movement of the drive block boss 431. The movement of the locking drive block 43 is thus restricted. It should be noted that the width of the limiting groove 411 is smaller than the width of the locking drive block 43, and the width of the limiting boss 161 is smaller than the width of the limiting groove 411. The surface of the second slider 16 is provided with a third plane 162 and a fourth plane 163 of different heights. The surface of the locking housing 41 is also provided with a second lifting slide groove 412. The second lifting slide groove 412 is provided with a second lifting slider 5. The top of the second lifting slider 5 is connected to a metal plate 6. The metal plate 6 has a certain toughness. The bottom of the second lifting slider 5 is attached to the third plane 162 or the fourth plane 163. A signal output plate 7 is provided on one side of the second lifting slide groove 412. When the bottom of the second lifting slider 5 is attached to the third plane 162, the signal output plate 7 and the metal plate 6 do not contact each other.

[0030] Working principle and usage of this invention:

[0031] When the door hook is inserted:

[0032] The locking hook inserts into the first insertion port 111, causing the cam 11 to rotate. The locking hook gradually presses the second slider 16 to move to the left. At this time, the third spring 15 is compressed, causing the inclined boss 164 at one end of the second slider 16 to gradually disengage from the boss slot 17. During the movement, the position of the limiting boss 161 changes, thus failing to restrict the movement of the drive block boss 431. Therefore, the locking drive block 43 can slide normally. As the cam 11 rotates, the first slider 2 gradually stops adhering to the side wall of the cam 11. Under the reaction force of the first spring 3, the first slider 2 pops out to the lower right corner until it slides into the locking hook inlet 12. When the first slider 2 moves to the lower right under the reaction force of the first spring 3, it will drive the first support block 22 to slide to the right on the guide rib 18. During the movement, the first inclined surface 222 gradually fits against the bottom of the first lifting slider 24, so the first lifting slider 24 will slide down the first lifting groove 410. After the first lifting slider 24 descends, the conductive spring 474 can be energized with the conductive plate 8. At this time, the door closing sensing is completed through the structure. It is equivalent to the end of the conductive rod 473 being connected to the external power supply. The external circuit will give a pulse signal to energize it. After the coil 471 is energized, the pull rod 472 will be driven upward under the action of electromagnetic force. When the locking drive block 43 moves downward once, the locking drive block 43 will be pushed to the uppermost position, i.e., the locking slot, under the elastic action of the second spring 44 being compressed. The guide cylinder 491 will then slide on the second parallel surface 403 until it slides past the second inclined surface 404 and into the guide groove. The change in the height of the guide cylinder 491 enables the locking block 49 to move downward inside the locking notch 48. At this time, the locking block 49 is locked inside the locking hole groove 21, thus locking the first slider 2. The locking of the first slider 2 interferes with the cam 11, restricting the rotation of the cam 11, and the external locking hook cannot be easily pulled out; the second As the slider 16 slides to the left under the pressure of the locking hook or the rotating cam 11, the bottom of the second lifting slider 5 gradually stops adhering to the third plane 162 until it slides to the fourth plane 163. That is, the second lifting slider 5 slides downward inside the second lifting groove 412. After the second lifting slider 5 moves downward, the metal plate 6 will move downward under the action of toughness. Since the metal plate 6 has a certain toughness, the metal plate 6 will gradually close with the signal output board 7, and the circuit will flow into the signal output board 7 through the metal plate 6. At this time, the signal output board 7 can transmit a door hook locked signal to the washing machine, and the washing machine can then work normally.

[0033] When the door hook is pulled out:

[0034] First, the end of the conductive rod 473 connected to the external power supply will conduct another pulse signal. After the coil 471 is energized, the pull rod 472 will move downward under the action of electromagnetism. The pull rod 472 will pull the locking drive block 43 downward once. Under the elastic action of the second spring 44 being squeezed, it will be pushed to the position of the unlocking slot. The guide cylinder 491 will slide through the second inclined surface 404 under the guidance of the guide groove until it slides on the second parallel surface 403. Therefore, the locking drive block 43 slides through the middle, realizing the upward movement of the locking block 49 inside the locking notch 48. At this time, the locking block 49 can no longer lock the first slider 2. The locking block 49 will disengage from the inside of the locking hole slot 21, realizing the unlocking of the first slider 2. The cam 11 can rotate normally, and the user can easily pull out the lock hook. During the pulling process, the cam 11 pushes the first slider 2 to the upper left corner again. During the movement of the first slider 2, it will drive the first support block 22 to the left. The first parallel surface 221 gradually The bottom of the first lifting slider 24 is attached to the first lifting slide 410, so the first lifting slider 24 will slide upward. After the first lifting slider 24 rises, the conductive spring 474 and the conductive plate 8 are disconnected, and the coil 471 will no longer be energized. At the same time, after the door hook is pulled out, the reaction force of the third spring 15 will push the second slider 16 to the right. The inclined boss 164 at one end of the second slider 16 will also be locked back into the boss slot 17. During the sliding process of the second slider 16, the bottom of the second lifting slider 5 gradually separates from the fourth plane 163 until it is attached to the third plane 162. That is, the second lifting slider 5 slides upward inside the second lifting slide 412. After moving upward, the second lifting slider 5 will pull the metal plate 6 upward. Since the metal plate 6 has a certain toughness, the metal plate 6 will gradually disconnect from the signal output board 7. The circuit cannot flow into the signal output board 7 through the metal plate 6. At this time, the signal output board 7 cannot transmit the door hook locked signal to the washing machine, and the washing machine cannot or stops working.
