[0044] like Figs. 1-3 As shown, this utility model provides a door lock structure, which includes a latch 1, a door lock 2, and a lock structure. The latch 1 is disposed on the appliance's housing, and the door lock 2 is disposed on the appliance's door. The lock structure may include a first lock assembly and a second lock assembly. The first lock assembly is adapted to engage and lock the latch 1 and the door lock 2 when the appliance's door is closed relative to the housing, that is, to lock the latch 1 on the housing and the door lock 2 on the door through the first lock assembly, thereby achieving pre-locking of the door relative to the housing. It should be noted that the appliances involved in this utility model may include, but are not limited to, dishwashers, washing machines, microwave ovens, etc. The following embodiments mainly use dishwashers as an example for illustration.

[0045] The second lock assembly includes a first locking element 13, an electromagnet 10, and a magnetic drive element 12. The first locking element 13 can be positioned between a first locked position and a first unlocked position on the door lock 2. The first locked position indicates that the first locking element 13 locks the latch 1 and the door lock 2; the first unlocked position indicates that the first locking element 13 unlocks the latch 1 and the door lock 2. The electromagnet 10 is energized when the latch 1 and the door lock 2 are locked together by the first lock assembly. That is, after the latch 1 and the door lock 2 are locked together by the first lock assembly, the electromagnet is switched from a non-energized state to an energized state. The magnetic drive element 12 can generate a magnetic force with the energized electromagnet 10, meaning the magnetic drive element 12 can cooperate with the electromagnet 10 to adjust the position of the first locking element 13. The magnetic drive component 12 is adapted to drive the first locking component 13 to move from the first unlocked position to the first locked position under the action of the magnetic force, that is, to lock the latch 1 on the box and the door lock 2 on the door again through the second lock assembly, thereby realizing the secondary locking of the door relative to the box.

[0046] The above embodiment, the lock mechanism in the door lock structure includes a first lock assembly and a second lock assembly, the first lock assembly is suitable for locking the lock catch 1 and the door lock 2 when the door body is closed. The electromagnet 10 in the second lock assembly can be in an energized state when the lock catch 1 and the door lock 2 are locked by the first lock assembly, and the first locking piece 13 in the second lock assembly is driven to move to the first locking position under the magnetic force between the energized electromagnet 10 and the magnetic drive piece 12 in the second lock assembly. In this way, the pre-locking of the door body of the electrical appliance is realized by the first lock assembly, and the electromagnet 10 in the second lock assembly is controlled to be energized when the first lock assembly is pre-locked, and then the second lock assembly is re-locked in combination with the magnetic drive piece 12 in the second lock assembly, so as to ensure the stability of the locking by double locking, and then the sealing effect after closing the door can be ensured, and the difficulty of opening the door body during use is increased, so that the door body is not easy to be opened by children, and the safety of the electrical appliance is improved.

[0047] In an optional embodiment, the second lock assembly further includes a first elastic member 11, one end of the first elastic member 11 is connected with the magnetic drive piece 12, and the other end of the first elastic member 11 is connected with the electromagnet 10. Optionally, the first elastic member 11 can include but is not limited to at least one of a spring, an elastic diaphragm, a bellows, etc. The first elastic member 11 can be connected with the magnetic drive piece 12 or the electromagnet 10 in any manner such as a fixed manner or a detachable manner.

[0048] When the electromagnet 10 is in an energized state, the elastic force of the first elastic member 11 is smaller than the magnetic force. Specifically, in the present embodiment, the magnetic poles of the electromagnet 10 and the magnetic drive piece 12 opposite to each other after being energized are the same, and the magnetic force generated therebetween can be repulsive force. In the case where the elastic force of the first elastic member 11 is smaller than the magnetic force, i.e. in the case where the repulsive force between the electromagnet 10 and the magnetic drive piece 12 after being energized is greater than the elastic force of the first spring member, the first elastic member 11 can be stretched and the magnetic drive piece 12 can be driven to move by the repulsive force, and then the first locking piece 13 can be driven to move by the magnetic drive piece 12, so that the first locking piece 13 moves from the first unlocking position to the first locking position. Optionally, the magnetic drive piece 12 can be a magnetic element, such as but not limited to at least one of a magnet and a magnetic block.

[0049] In an optional embodiment, when the electromagnet 10 is in a non-energized state, the first elastic member 11 can drive the first locking piece 13 to move to the first unlocking position. Specifically, if the electromagnet 10 is in a non-energized state, the first elastic member 11 in a stretched state can return to an initial length state under the elastic force of the first elastic member 11, and drive the first locking piece 13 to reset from the first locking position to the first unlocking position.

[0050] Optionally, the unpowered state can be related to the position of the first locking member 13 and the switch state of an unlocking switch in the electrical appliance. Specifically, if the position of the first locking member 13 cannot reach the powered state of the electromagnet 10, the electromagnet 10 is in the unpowered state. Alternatively, if the position of the first locking member 13 can reach the powered state of the electromagnet 10, and the switch state of the unlocking switch in the electrical appliance is in the open state, the electromagnet 10 is in the unpowered state. The unlocking switch can be provided on the shell of the electrical appliance, and the user can adjust the switch state of the unlocking switch to the open state by touching or operating the unlocking switch, so that the electromagnet 10 is powered off.

[0051] In this way, by adding the first elastic member 11, the magnetic force is restrained by the elastic force of the first elastic member 11, so that the relocking process is more gentle. In addition, under the action of the first elastic member 11, the first locking member 13 can be quickly moved to the first unlocking position in the case of disappearance of the magnetic force, and the smoothness of the opening of the electrical appliance is improved.

[0052] In an optional embodiment, the locking member 1 is provided with a first locking slot 14. The first locking slot 14 is provided with a control switch 7, and the control switch 7 is electrically connected with the electromagnet 10. When the first locking assembly abuts against the control switch 7, the control switch 7 can control the electromagnet 10 to be in the powered state. Specifically, the control switch 7 can include at least one elastic sheet, and the position of the at least one elastic sheet can adjust the control switch 7 to be in the open state or the closed state. When the first locking assembly moves and extends into the first locking slot 14 and abuts against the control switch 7, the control switch 7 is in the open state. The control switch 7 can be electrically connected with the control circuit of the electrical appliance, and the control circuit is turned on by opening the control switch 7, and then the control circuit controls the electromagnet 10 to be in the powered state.

[0053] Optionally, the control switch 7 can cooperate with the unlocking switch in the electrical appliance. When the electromagnet 10 is controlled by the control switch 7 to be in the powered state, and the electrical appliance such as a dishwasher needs to be opened, the electromagnet 10 can be powered off by pressing the unlocking switch, and then the hidden locking of the locking member 1 and the door locking member 2 by the second locking assembly is contacted, so that the user can perform the door opening operation to release the locking of the first locking assembly, and then the door body is smoothly opened.

[0054] In this way, by providing the control switch 7 in the first locking slot 14 of the locking member 1, and controlling the electromagnet 10 to be powered when the first locking assembly abuts against the control switch 7, unnecessary locking action of the second locking assembly when the first locking assembly is not completely locked is avoided, and the operation reliability and stability of the door locking of the electrical appliance are improved.

[0055] In an optional embodiment, the door lock member 2 is provided with a first installation slot 9 corresponding to the first lock slot 14. The first lock assembly includes a second locking member 6 and a second elastic member 4. The second locking member 6 has a second locking position and a second unlocking position, the second locking position is suitable for cooperating the lock catch member 1 with the door lock member 2 to be locked, and the second unlocking position is suitable for the second locking member 6 to unlock the lock catch member 1 from the door lock member 2. The second elastic member 4 is arranged in the first installation slot 9, and the second elastic member 4 is suitable for driving the first locking member 13 to move between the second locking position and the second unlocking position.

[0056] In this way, by being able to accommodate the first installation slot 9 of the first lock assembly, the compactness of the door lock structure is improved. In addition, by arranging the first lock assembly to include the second locking member 6 and the second elastic member 4, the pre-locking is quickly realized by the elastic force of the second elastic member 4, and the structure and operation convenience of the door lock structure are simplified.

[0057] In an optional embodiment, the first lock assembly further includes a transition member 5 slidingly arranged in the first installation slot 9, one end of the transition member 5 is connected with the second locking member 6, and the other end can be in contact with the second elastic member 4. Specifically, the transition member 5 is slidingly arranged in the first installation slot 9, one end of the transition member 5 is connected with the second locking member 6, and the other end of the transition member 5 can be connected with one end of the second elastic member 4, and the other end of the second elastic member 4 can abut to the bottom of the first installation slot 9. The connection mode here can include but is not limited to at least one of fixed connection, detachable connection, etc. The second elastic member 4 drives the transition member 5, and then drives the first locking member 13 to move between the second locking position and the second unlocking position through the transition member 5.

[0058] In this way, by arranging the transition member 5 between the second locking member 6 and the second elastic member 4, the contact area of the second elastic member 4 acting on the second locking member 6 can be increased through the transition member 5, the acting force acting on the second locking member 6 is improved, and the second locking member 6 can be smoothly moved to the second locking position, thereby improving the operation convenience and reliability of the door lock structure.

[0059] In an optional embodiment, an arc-shaped taper surface is arranged on one end of the second locking member 6 close to the lock member 1. The arc-shaped taper surface can be arranged on both sides of the one end of the second locking member 6 close to the lock member 1. During the process of performing the closing operation of the door body, the arc-shaped taper surface on the one end of the second locking member 6 abuts against the lock member 1, and in the case that the abutting force is greater than the elastic force of the second elastic member 4, the abutting force on the second locking member 6 drives the transition member 5 to slide in the first mounting slot 9 to adjust the second elastic member 4 to be in the compressed state in the first mounting slot 9. With the continuous performance of the closing operation of the door body, the arc-shaped taper surface on the second locking member 6 is disengaged from the lock member 1, at which time the abutting force on the second locking member 6 disappears, and under the elastic force of the second elastic member 4, the second elastic member 4 recovers from the compressed state to the expanded state, and the second elastic member 4 drives the transition member 5 to slide in the first mounting slot 9 towards the direction of the first lock slot 14 to drive the one end of the second locking member 6 to move towards the first lock slot 14 and be clamped into the first lock slot 14, thereby realizing the locking of the lock member 1 and the door lock member 2 by the first lock assembly. Optionally, the second locking member 6 can include a lock block capable of being inserted into the first mounting slot 9.

[0060] In this way, by arranging the arc-shaped taper surface on the second locking member 6, the first lock assembly can smoothly realize the pre-locking while simplifying the door lock structure, thereby further improving the operation convenience and reliability of the door lock structure.

[0061] In an optional embodiment, the lock member 1 is provided with a second lock slot 8, and when the first locking member 13 is located at the first locking position, one end of the first locking member 13 is clamped into the second lock slot 8. When the first locking member 13 is located at the first unlocking position, the end of the first locking member 13 does not extend into the second lock slot 8. Optionally, the first locking member 13 can include a clamping block capable of being inserted into the second mounting slot 3.

[0062] In an optional embodiment, the door lock member 2 is provided with a second mounting slot 3, the electromagnet 10 can be accommodated at the bottom of the second mounting slot 3, and the magnetic driving member 12 can be slidingly arranged in the second mounting slot 3.

In the second mounting slot 3, the electromagnet 10 can be arranged at the bottom of the second mounting slot 3, and the magnetic driving member 12 can be slidingly connected with the first elastic member 11 and the first locking member 13 in the second mounting slot 3.

[0063] Optionally, the second lock slot 8 and the first lock slot 14 can be arranged side by side on the same side surface of the lock member 1. The second mounting slot 3 and the first mounting slot 9 can be arranged side by side on the same side surface of the door lock member 2.

[0064] In this way, by introducing the second lock slot 8 and the corresponding second mounting slot 3 to accommodate the first lock assembly, the compactness of the door lock structure is further improved, and the safety of the door lock structure can be ensured.

[0065] The following description, in conjunction with the accompanying drawings and using a dishwasher as an example, details a door lock structure and its working process provided by this utility model.

[0066] like Figs. 1-3 As shown, the door lock structure includes a latch 1 and a door lock 2. The latch 1 is mounted on the dishwasher, and the door lock 2 is mounted on the dishwasher door. The door lock structure also includes a lock structure for locking the latch 1 and the door lock 2 together, which includes a first lock assembly and a second lock assembly. The door lock 2 has a first mounting groove 9 and a second mounting groove 3, and the latch 1 has corresponding first locking groove 14 and second locking groove 8.

[0067] The first locking assembly includes a second locking element 6 (such as a locking block), a transition element 5 (such as a slider), and a second elastic element 4 (such as a spring). The second locking element 6, capable of resetting, is slidably connected within the second mounting groove 3. The transition element 5 is also slidably connected within the second mounting groove 3. The second elastic element 4 is installed between the transition element 5 and the second mounting groove 3, and the second locking element 6 can be fixed to the transition element 5. When the dishwasher door is closed, the second mounting groove 3 and the second locking groove 8 are opposite each other, and the second locking element 6 enters the second locking groove 8. Since the end of the second locking element 6 away from the transition element 5 is set with an arc-shaped conical surface, the arc-shaped conical surface abuts against the latch element 1. This compression drives the second locking element 6 and the transition element 5 to slide within the second mounting groove 3, compressing the second elastic element 4, thus closing the dishwasher door. After the dishwasher door is closed, the second elastic element 4 releases the compressive force, and under its action, the second locking element 6 and the transition element 5 reset.

[0068] Since a control switch 7 is installed in the second locking groove 8, the second locking member 6 extends into the second locking groove 8 and abuts against the control switch 7, which is in the open state, i.e., the energized state. The control switch 7 is electrically connected to the electromagnet 10 and can also control the switching of the entire dishwasher circuit. If the control switch 7 is not turned on and energized, that is, the second locking member 6 is not locked and engaged in the second locking groove 8, the dishwasher cannot be opened and used.

[0069] The second lock assembly comprises a first locking piece 13 (such as a clamping block), an electromagnet 10, a magnetic driving piece 12 (such as a magnetic block) and a first elastic piece 11 (such as a spring). The first locking piece 13 driven and capable of resetting is slidably arranged in the first lock slot 14, and the first locking piece 13 extends into the first lock slot 14 to lock the lock catch 1 and the door lock 2. The electromagnet 10 is installed in the first installation slot 9, the magnetic driving piece 12 is slidably connected in the first installation slot 9, the first elastic piece 11 is fixed on the electromagnet 10 and the magnetic driving piece 12, and the first locking piece 13 can be fixed on the magnetic driving piece 12. The second locking piece 6 in the first lock assembly extends into the second lock slot 8 and abuts against the control switch 7, at this time the electromagnet 10 is powered on, because the magnetic driving piece 12 and the electromagnet 10 are arranged with the same magnetic poles on the opposite surfaces, and the repulsive force between the magnetic driving piece 12 and the electromagnet 10 is greater than the elastic force of the first elastic piece 11, so that the magnetic driving piece 12 and the first locking piece 13 can be driven to move, the first locking piece 13 is clamped into the first lock slot 14, and locking is realized.

[0070] In addition, the dish washing machine further has another unlocking switch cooperating with the control switch 7, such as a double-opening switch, when the door of the dish washing machine needs to be opened, the unlocking switch can be pressed to power off the electromagnet 10, and under the action of the first elastic piece 11, the first locking piece 13 is reset to realize unlocking.

[0071] On the other hand, the utility model also provides a kind of electric appliance (not shown), including door body (not shown), box body (not shown) and the door lock structure of any of the above described. Box body and door body are switched by door lock structure to realize the switching of door closing and door opening operation.Exemplarily, electric appliance can include but not limited to dish washing machine, washing machine, microwave oven and the like.

[0072] It should be noted that the specific structure of the door body and the box body of the electric appliance is not specifically limited here.The specific details of the door lock structure can be referred to the foregoing embodiments, which will not be repeated here.

[0073] The above embodiment, because the door lock structure in the electrical appliance comprises a first lock assembly and a second lock assembly, the first lock assembly is adapted to lock the lock catch and the door lock piece when the door body is closed. The electromagnet in the second lock assembly can be in an energized state when the lock catch and the door lock piece are locked by the first lock assembly, and the first locking piece in the second lock assembly is driven to move to a first locking position by the magnetic force between the energized electromagnet and the magnetic driving piece in the second lock assembly. In this way, the pre-locking of the door body of the electrical appliance is realized by the first lock assembly, and the electromagnet in the second lock assembly is controlled to be energized when the first lock assembly is pre-locked, and then the re-locking of the second lock assembly is realized in combination with the magnetic driving piece in the second lock assembly, the stability of the locking is ensured by double locking, and then the sealing effect after the door is closed can be ensured, and the difficulty of opening the door body during use is increased, so that the door body is not easy to be opened by children, and the safety of the electrical appliance is improved

[0074] The above is the preferred embodiment of the present application, it should be pointed out that, for those skilled in the technical field, without departing from the principles of the present application, can make a number of improvements and refinements, these improvements and refinements also as the protection scope of the present application.
