Technical Field

[0001] This utility model relates to the field of dishwasher technology, and in particular to a dishwasher door anti-fall device and a dishwasher. Background Technology

[0002] In related technologies, dishwashers use an automatic door opening solution. After the dishwasher opens automatically, there is a risk that the door may fall, which could cause an accidental safety incident and affect the user experience. Utility Model Content

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a door anti-fall device for a dishwasher, which helps to reduce the risk of the door falling after automatic opening and reduces the possibility of accidents.

[0004] According to an embodiment of the present invention, a dishwasher door anti-fall device is provided. The dishwasher includes a body and a door. The dishwasher door anti-fall device includes: a buffer member, at least partially elastic, connected between the body and the door to apply a restoring force to the door to prevent it from opening; a detection member, connected to the body and having a detection part; a sliding member and an elastic member, the two ends of the elastic member being connected to the sliding member and the body respectively, the sliding member being movable relative to the body, and the elastic member being used to apply a pulling force to the sliding member to drive it towards the detection member; wherein the sliding member is configured such that: when the buffer member is not in failure, the sliding member is limited by the buffer member to separate the detection member and the sliding member; when the buffer member fails, the sliding member moves to a set position under the pulling force of the elastic member to trigger the detection part, causing the detection part to generate a door anti-fall signal.

[0005] The dishwasher door anti-fall device according to an embodiment of this utility model comprises a detection element, a sliding element, and an elastic element. When the buffer element is intact, the sliding element is limited by the buffer element, thus separating the detection element and the sliding element. When the buffer element fails, the sliding element moves to a set position under the tension of the elastic element to trigger the detection unit, which generates a door anti-fall signal. This allows the user to promptly detect buffer element failure, reducing the risk of the door falling after automatic opening and minimizing the possibility of accidents. Furthermore, the elastic element applies tension to the sliding element; that is, when the buffer element is intact, the elastic element is in a stretched state. This eliminates the need for a guide element to limit the deformation of the elastic element, and the stretched elastic element can be connected to the sliding element and the machine body using a simpler installation structure. Therefore, it reduces the space occupied by the dishwasher door anti-fall device, allowing it to better meet the layout requirements of compact models.

[0013] According to some embodiments of the present invention, the sliding member has a first abutting portion, and the mounting base has a first abutting block. Along the moving direction of the sliding member, the first abutting portion is located on the side of the first abutting block away from the detection member. When the sliding member is in a set position, the first abutting portion and the first abutting block abut against each other to limit the maximum moving position of the sliding member toward the detection member.

[0014] According to some embodiments of the present invention, the sliding member is provided with a protrusion for connecting to one end of the elastic member, both ends of the first abutting block are connected to the sidewall of the first recess, and the first abutting block is at least partially disposed away from the first recess to avoid the protrusion.

Along the moving direction of the sliding member, in the state where the buffer member is not in failure, the second abutting block can abut and cooperate with the second abutting portion to limit the maximum moving position of the sliding member away from the detection member.

[0016] According to some embodiments of the present invention, the first end of the buffer is connected to the door body. When the buffer is not in failure, the sliding member is limited by the first end of the buffer, and the elastic member and the detection member are located on the upper side of the first end.

[0017] According to some embodiments of the present invention, the buffer includes a tension spring and a pull rope connected together to connect the door body and the machine body; wherein, in the state where the buffer is not in failure, the sliding member is limited by the pull rope.

Detailed Implementation

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] Dishwashers are kitchen appliances that automatically clean dishes and are gradually becoming a common household appliance. They typically include a drying function to quickly dry dishes after washing, preventing bacterial growth in damp environments.

[0026] After the dishwasher's washing cycle ends, a higher temperature is required for drying. To address the issue of high energy consumption, related technologies have implemented a feature where the dishwasher door automatically opens at a certain angle after the washing cycle to quickly expel the hot and humid air inside, achieving better drying results and reducing energy consumption.

[0027] In related technologies, the dishwasher door is connected to the machine body via a buffer to facilitate control of the door's opening angle. If the buffer fails, it cannot provide the necessary tension. If the dishwasher door opens automatically at this time, it will fall rapidly, posing a risk of injuring users, children, or pets.

[0028] Based on the aforementioned technical problems, this application provides a dishwasher door anti-fall device. The dishwasher door anti-fall device includes a buffer, a detection element, a sliding element, and an elastic element. The buffer is at least partially elastic and is connected between the machine body and the door to apply a restoring force to the door to prevent it from opening. The detection element is connected to the machine body and has a detection section. The two ends of the elastic element are respectively connected to the sliding element and the machine body. The sliding element is movable relative to the machine body, and the elastic element applies a pulling force to the sliding element to drive it towards the detection element. The sliding element is configured such that, in the state where the buffer is intact, the sliding element is limited by the buffer to separate the detection element from the sliding element; in the state where the buffer fails, the sliding element moves to a set position under the pulling force of the elastic element to trigger the detection element, causing the detection element to generate a door anti-fall signal. The dishwasher door anti-fall device of this application embodiment can reduce the risk of the door falling after automatic opening and reduce the possibility of accidents.

[0029] Figure 1 This is a structural schematic diagram of a dishwasher 1000 according to some embodiments of the present invention. Figure 2 It shows Figure 1 The structural diagram of the base 400 and the door 300 is shown below. (Refer to...) Figure 1 and Figure 2 The dishwasher 1000 includes a body 200 and a door 300. The body 200 has a cleaning chamber and a loading port. The loading port is connected to the cleaning chamber. Dishes can be placed into or taken out of the cleaning chamber through the loading port. The cleaning chamber is used to hold and clean the dishes.

[0030] The dishwasher door anti-fall device 100 includes a buffer 10, which is at least partially elastic. The buffer 10 is connected between the machine body 200 and the door 300 to apply a restoring force to the door 300 to prevent it from opening. For example, the door 300 is closably connected to the loading port of the machine body 200. The buffer 10 is connected between the door 300 and the machine body 200. The buffer 10 is at least partially elastic and has a first end and a second end. The first end of the buffer 10 is connected to the door 300, and the second end is connected to the machine body 200. When the door 300 moves relative to the machine body 200, the elastic portion of the buffer 10 deforms synchronously and moves with the door 300 to provide a buffering pull on the door 300, preventing it from falling rapidly and allowing the door 300 to open and remain at one or any angle.

[0031] If the buffer 10 fails and cannot apply the corresponding pulling force to the door 300, the door 300 will open automatically and then fall rapidly, creating a safety hazard. It should be noted that the failure of the buffer 10 refers to insufficient elastic deformation of the buffer 10, or the buffer 10 falling off or breaking.

[0032] In some embodiments, the side of the door 300 is connected to the body 200 via a hinge, and the top of the door 300 is connected to a door lock assembly provided on the body 200. The door lock assembly can automatically open the door 300 after the dishwasher 1000 has completed the corresponding program, so that the hot and humid air inside the dishwasher 1000 can be quickly discharged to achieve a better drying effect and reduce energy consumption.

[0033] For example, the buffer 10 may include a first part and a second part connected together, the first part being elastic and the second part being non-elastic. Alternatively, the buffer 10 may also be elastic as a whole, for example, as an elastic rope, without being specifically limited here.

[0034] The dishwasher door anti-fall device 100 also includes a detection element 20, a sliding element 30, and an elastic element 40. The detection element 20 is used to connect to the body 200 and has a detection part 201. The two ends of the elastic element 40 are respectively connected to the sliding element 30 and the body 200. The sliding element 30 can move relative to the body 200. The elastic element 40 is used to apply a pulling force to the sliding element 30 to drive the sliding element 30 to move toward the detection element 20.

[0035] The slider 30 is configured such that, when the buffer 10 is not in failure, the slider 30 is limited by the buffer 10 to separate the detector 20 and the slider 30; when the buffer 10 fails, the slider 30 moves to a set position under the pulling force of the elastic member 40 to trigger the detector 201, so that the detector 201 generates a door anti-fall signal.

[0036] It should be noted that when the buffer 10 is functioning correctly, during the opening and closing of the door 300, the sliding member 30 will move within a certain range, but will not contact the detection element 20 nor separate from the buffer 10. When the buffer 10 is functioning correctly and the door 300 is not moving, the pressure exerted by the buffer 10 on the sliding member 30 will be balanced by the tension exerted by the elastic element 40 on the sliding member 30, thus keeping the sliding member 30 in a certain position in space. When the buffer 10 fails, the pressure exerted by the buffer 10 on the sliding member 30 disappears, and the sliding member 30 is only subjected to the tension from the elastic element 40. Therefore, under the action of the tension, the sliding member 30 moves to a set position to contact the detection unit 201, triggering the detection unit 201 to generate a door anti-fall signal.

[0037] Here, the set position refers to the position where the slider 30 is closest to the detector 20, or the position where the slider 30 can contact the detector 201 and trigger the detector 20.

[0038] For example, the detection unit 201 can be a separate sensor unit, and the detection unit 201 is communicatively connected to the actuator. After receiving the door anti-fall signal, the actuator performs the corresponding operation; or, the detection unit 20 is a switch, and the detection unit 201 is a transmission element or actuating spring of the switch.

[0039] When the actuator receives the door anti-fall signal, for example, if the actuator is the display unit of the dishwasher 1000, the display unit of the dishwasher 1000 can display the corresponding abnormal code to remind the user and facilitate after-sales personnel to repair; for example, if the actuator is the door lock assembly, the door lock assembly can remain in the locked state when it receives the door anti-fall signal to prevent the door 300 from falling after it is opened.

[0040] For example, the elastic element 40 can be a tension spring 102. To facilitate the installation of the elastic element 40, a third protrusion 506 can be provided on the body 200, and the sliding element 30 can have a protrusion 302. For example, the third protrusion 506 and the protrusion 302 can be hooks or protrusions with limiting grooves, so that both ends of the elastic element 40 can be hooked onto the sliding element 30 and the body 200. For example, the sliding element 30 can be directly or indirectly provided on the body 200.

[0041] According to the embodiments of this application, the dishwasher door anti-fall device 100 is provided with a detection element 20, a sliding element 30, and an elastic element 40. When the buffer element 10 is not in failure, the sliding element 30 is limited by the buffer element 10, so that the detection element 20 and the sliding element 30 are separated. When the buffer element 10 fails, the sliding element 30 moves to a set position under the pulling force of the elastic element 40 to trigger the detection unit 201, so that the detection unit 201 generates a door anti-fall signal. This helps the user to detect the failure of the buffer element 10 in time, reduces the risk of the door 300 falling after automatic opening, and reduces the possibility of accidents. Furthermore, the elastic element 40 is used to apply tension to the sliding element 30. That is, when the buffer 10 is not in failure, the elastic element 40 is in a stretched state. In this way, there is no need to set a guide to limit the deformation of the elastic element 40. At the same time, the elastic element 40 in the stretched state can also adopt a simpler installation structure to achieve the connection with the sliding element 30 and the body 200. Therefore, it is beneficial to reduce the space occupied by the dishwasher door anti-fall device 100, so that the dishwasher door anti-fall device 100 of this application can better meet the arrangement requirements in a compact model.

[0042] Based on some embodiments of this utility model, a comparative reference can be made. Figure 3 and Figure 4 The sliding member 30 has a support portion, which is limited by the buffer member 10. When the buffer member 10 is not in failure, the elastic member 40 is in a stretched state.

[0043] For example, the support portion can be a support block, and there are no specific limitations on the shape and size of the support block, as long as the buffer 10 can stably abut against the support block. Alternatively, the support portion can be a support wheel 306 to reduce the friction between the support portion and the buffer 10. For example, the support portion can also be a support groove formed in the slider 30, in which the buffer 10 passes through the support groove and abuts against the wall of the support groove when the buffer 10 is not in failure.

[0044] When the buffer 10 is not in failure, the elastic element 40 is in a stretched state. In this way, there is no need to set a guide to limit the deformation of the elastic element 40. At the same time, the elastic element 40 in the stretched state can also adopt a simpler installation structure to achieve the connection with the sliding element 30 and the body 200. Therefore, it is beneficial to reduce the space occupied by the dishwasher door anti-fall device 100, so that the dishwasher door anti-fall device 100 of this application can better meet the arrangement requirements in compact models.

[0045] According to some embodiments of the present invention, along the moving direction of the sliding member 30, the detection member 20 and the elastic member 40 are located on the same side of the support.

[0046] In this embodiment, the detection element and the elastic element are located on the same side of the support part along the moving direction of the sliding element. This reduces the size of the entire dishwasher door anti-fall device 100 along the moving direction of the sliding element 30, thereby reducing the space occupied by the dishwasher door anti-fall device 100. This allows the dishwasher door anti-fall device 100 of this application to better meet the arrangement requirements in compact models.

[0047] According to some embodiments of this utility model, it can be referred to Figure 2 and Figure 3 The support part is a support wheel 306, which is rotatably mounted on the sliding member 30. When the buffer member 10 is not in failure, the support wheel 306 is limited by the buffer member 10. For example, the support wheel 306 abuts against the buffer member 10.

[0048] For example, the pull cord 103 of the buffer 10 passes around the support wheel 306. On the one hand, this restricts the position of the sliding member 30. On the other hand, during the opening and closing of the door 300, the reciprocating movement of the pull cord 103 also generates friction with the support wheel 306 to balance the weight of the door 300, allowing it to accommodate heavier doors 300. The pull cord 103 is supported by the support wheel 306, which also keeps the pull cord 103 taut. In addition, the support wheel 306 is rotatably connected to the sliding member 30, so that the pull cord 103 of the buffer 10 and the support wheel 306 form rolling friction, reducing the friction between the pull cord 103 and the support wheel 306. This allows the pull cord 103 to move smoothly on the support wheel 306, reducing the wear of the pull cord 103 and increasing its service life.

[0049] According to some embodiments of this utility model, it can be referred to Figures 2 to 9 The dishwasher door anti-fall device 100 also includes a mounting base 50, which is used to mount the machine body 200. The sliding member 30 and the detection member 20 are both mounted on the mounting base 50. The sliding member 30 is movable relative to the mounting base 50, and the detection member 20 is set on the movement path of the sliding member 30.

[0050] The detection element 20 is positioned on the moving path of the slider 30 so that the slider 30 can contact the detection element 20 after moving a certain distance, and the trigger element can trigger the detection part of the detection element 20.

[0051] For example, the body 200 may include a base 400, the door 300 is rotatably mounted on the base 400, the mounting base 50 may be integrally formed on the base 400, or the mounting base 50 may be connected to the base 400 by bolts or snap-fit.

[0052] For example, the slider 30 and the detector 20 may be located on the same side of the mounting base 50 along a set direction, or the slider 30 and the detector 20 may be located on different sides of the mounting base 50 along a set direction. The set direction forms a set angle with the sliding direction of the slider 30, for example, the set direction is perpendicular to the sliding direction of the slider 30.

[0053] The mounting base 50 is provided to provide mounting positions for the elastic element 40, the detection element 20, and the sliding element 30. The detection element 20 and the elastic element 40 are respectively located on both sides of the mounting base 50 in the set direction. In this way, the elastic element 40 and the detection element 20 will not interfere with each other, and the detection element 20 does not need to be designed with a special structure to avoid the elastic element 40. Therefore, it is beneficial to reduce the difficulty and cost of layout.

[0054] According to some embodiments of this utility model, it can be referred to Figures 2 to 9The mounting base 50 has a first recess 504 and a second recess 507. At least a portion of the slider 30 is disposed in the first recess 504, and at least a portion of the detection element 20 is disposed in the second recess 507. The recesses of the first recess 504 and the second recess 507 are in opposite directions, so that the projection of the slider 30 and the projection of the detection element 20 at least partially overlap along the moving direction F of the slider 30.

[0055] The above technical solution accommodates at least a portion of the sliding member 30 by providing a first recess 504 and at least a portion of the detection member 20 by providing a second recess 507. In this way, along the moving direction F of the sliding member 30, the projection of the sliding member 30 and the projection of the detection member 20 can at least partially overlap. That is to say, the arrangement of the sliding member 30 and the detection member 20 is more compact, which helps to reduce the size of the dishwasher door anti-fall device 100 in the setting direction, so that the dishwasher door anti-fall device 100 of this application can better meet the arrangement requirements in a compact model.

[0056] Furthermore, the first recess 504 can also restrict the spatial position of the main body 305 of the slider 30 during movement, preventing the slider 30 from shifting too much during movement, which could lead to failure to trigger the detection part 201 of the detection element 20 or interference with surrounding components. The main body 305 of the slider 30 is in clearance fit with the first recess 504, ensuring that the first recess 504 does not excessively obstruct the movement of the slider 30, thus facilitating smooth sliding of the slider 30 to the detection part 201 of the trigger detection element 20.

[0057] The first recess 504 and the second recess 507 have opposite recess directions, which helps to increase the overall strength of the mounting base and facilitates the stable installation of the sliding member 30 and the detection member 20.

[0058] According to some embodiments of the present invention, the first recess 504 and the second recess 507 are interconnected through the through region 501. When the slider 30 is in a set position, a portion of the detection member 20 and / or a portion of the slider 30 passes through the through region 501.

[0059] For example, the elastic member 40 may be located on the same side of the mounting base 50 in the set direction as the sliding member 30. The mounting base 50 is formed with a through region 501 that extends through the set direction, so that when the sliding member 30 is in the set position, a portion of the sliding member 30 passes through the through region 501 to contact the detection part 201 of the detection member 20.

[0060] For example, the elastic member 40 may be located on the same side of the mounting base 50 in the set direction as the sliding member 30. The mounting base 50 is formed with a through region 501 extending in the set direction, so that when the sliding member 30 is in the set position, a portion of the detection member 20 passes through the through region 501 to contact a portion of the sliding member 30.

[0061] For example, the elastic member 40 may be located on the same side of the mounting base 50 in the set direction as the sliding member 30. The mounting base 50 is formed with a through area 501 that extends through the set direction, so that when the sliding member 30 is in the set position, both the portion of the detection member 20 and the portion of the sliding member 30 pass through the through area 501 and come into contact with each other.

[0062] In other embodiments, the detection element 20 and the sliding element 30 may also be located on the same side of the mounting base 50 in a set direction. In this case, a portion of the sliding element 30 or a portion of the elastic element 40 passes through the through area 501 to be connected to each other.

[0063] For example, the outline of the through region 501 can be a closed outline, that is, the through region 501 can be a through hole, or the through region 501 can also be an open outline.

[0064] According to some embodiments of this utility model, it can be referred to Figure 10 and Figure 11 The slider 30 includes a trigger part 301 and a main body part 305. The trigger part 301 can be integrally formed on the main body part 305.

[0065] The triggering part 301 is used to contact the detection part 201 when the slider 30 is in a set position, so as to trigger the detection part 20.

[0066] In other words, when the slider 30 is in the set position, the trigger 301 can stop the detection unit 201 so that the detection unit 20 generates a door anti-fall signal.

[0067] You can refer to Figure 11 The triggering part 301 may include a plate part 3011 and a support part 3012 provided on the side of the plate part 3011 facing away from the detection member 20. The plate part 3011 and the support part 3012 are connected. The plate part 3011 and the support part 3012 are integrally formed on the main body part 305. The plate part 3011 and the main body part 305 are arranged at a set angle, for example, the plate part 3011 and the main body part 305 are perpendicular to each other, so that the structure of the protrusion 302 is more stable and less prone to deformation, thereby improving the triggering success rate of the detection part 201.

[0068] According to some embodiments of this utility model, it can be referred to Figure 3 and Figure 4 The slider 30 has a first abutting portion 303, and the mounting base 50 has a first abutting block 502. Along the moving direction F of the slider 30, the first abutting portion 303 is located on the side of the first abutting block 502 away from the detection member 20. When the slider 30 is in the set position, the first abutting portion 303 and the first abutting block 502 abut against each other to limit the maximum moving position of the slider 30 toward the detection member 20.

[0069] It should be noted that when the first abutting part 303 and the first abutting block 502 are in contact, the sliding member 30 can trigger the detection part 201 of the detection member 20. Alternatively, when the first abutting part 303 and the first abutting block 502 are spaced a certain distance apart, the sliding member 30 can trigger the detection part 201 of the detection member 20.

[0070] For example, when the first abutting part 303 and the first abutting block 502 are in abutting engagement, the sliding member 30 can be spaced apart from the rest of the detection member 20 except for the detection part 201, so as to reduce the possibility that the movement of the sliding member 30 will cause a large impact on the detection member 20 and damage the detection member 20.

[0071] In the above technical solution, by setting a first abutting part 303 and a first abutting block 502 that can abut against each other, the maximum moving position of the sliding member 30 towards the detection member 20 is limited. In this way, when the sliding member 30 moves towards the detection member 20, the first abutting block 502 can resist the impact generated by the rapid movement of the sliding member 30, thereby reducing the impact on the detection member 20, thus protecting the detection member 20 and reducing the possibility of the detection member 20 being damaged due to a large impact.

[0072] According to some embodiments of this utility model, it can be referred to Figures 3 to 5 , Figure 8 The sliding member 30 is provided with a protrusion 302 for connecting to one end of the elastic member 40. The two ends of the first abutting block 502 are connected to the sidewall of the first recess 504. The first abutting block 502 is at least partially disposed away from the first recess 504 to avoid the protrusion 302.

[0073] In the above embodiment, the two ends of the first abutment block 502 are connected to the mounting base 50. The first abutment block 502 is at least partially away from the first recess 504. On the one hand, the first abutment block 502 has better structural stability and is not easily deformed when subjected to external force. On the other hand, the first abutment block 502 can limit the main body 305 of the slider 30 to prevent the slider 30 from displacing perpendicular to one side of the mounting base 50 during the movement toward the detection member 20, so that the slider 30 moves as close as possible to the detection member 20.

[0074] The two ends of the first abutment block 502 are connected to the side wall of the first recess 504. The slider 30 passes through the space enclosed by the first abutment block 502 and the first recess 504 to limit the spatial position of the main body 305 of the slider 30 during movement, so as to avoid the slider 30 from shifting too much during movement, which would prevent the detection part 201 of the detection element 20 from being triggered or cause interference to the surrounding parts.

[0075] The main body 305 of the slider 30 is fitted with the first abutting block 502 with a clearance. In this way, the first abutting block 502 will not cause too much obstruction to the movement of the slider 30, which is conducive to the slider 30 being able to slide smoothly to the detection part 201 of the trigger detection member 20.

[0076] In the above technical solution, in order to facilitate the installation of the slider 30 and avoid interference between the protrusion 302 of the slider 30 and the first abutting block 502, the first abutting block 502 is at least partially disposed away from the first recess 504 in order to avoid the protrusion 302.

[0077] For example, the cross-section of the first abutment block 502 perpendicular to the moving direction of the slider 30 can be in the shape of a "Z". In this way, the first abutment block 502 can not only provide a good limiting effect for the slider 30, but also avoid interference between the protrusion 302 and the first abutment block 502.

[0078] According to some embodiments of this utility model, it can be referred to Figure 3 and Figure 4 The sliding member 30 has a second abutting portion 304, and the mounting base 50 has a second abutting block 503. Along the moving direction F of the sliding member 30, in the state where the buffer member 10 is not in failure, the second abutting block 503 can cooperate with the second abutting portion 304 to limit the maximum moving position of the sliding member 30 away from the detection member 20.

[0079] For example, the second abutment portion 304 may be a portion of the wall surface of the main body portion 305 of the slider 30, for example, along the moving direction F of the slider 30, the end face of the main body portion 305 of the slider 30 facing away from the detection member 20. Alternatively, the second abutment portion 304 may also be a protrusion protruding from the main body portion 305.

[0080] It should be noted that when the buffer 10 is not in failure, the sliding member 30 will move relative to the mounting base 50 within a certain range during the opening and closing of the door 300. Alternatively, after the buffer 10 fails, the elastic member 40 will drive the sliding member 30 to move within a certain range. By setting the second abutting block 503 and the second abutting part 304 that can limit the maximum movement position of the sliding member 30 away from the detection member 20, the possibility of the sliding member 30 hitting the surrounding parts due to excessive movement range is reduced, thus affecting the use effect of the surrounding parts.

[0081] According to some embodiments of the present invention, the mounting base 50 is formed with a connecting portion 505, which is used to be detachably connected to the body 200.

[0082] For example, the connecting part 505 can be a snap-fit ​​part, that is, the mounting base 50 is snap-fitted to the body 200; or, the connecting part 505 can be a mounting hole, through which bolts are inserted to install the mounting base 50 to the body 200 (see reference). Figure 3 ).

[0083] In the above technical solution, the connecting part 505 is used to detachably connect to the body 200, which facilitates the overall replacement and installation of the dishwasher door anti-fall device 100, and helps to improve the overall assembly efficiency of the dishwasher 1000.

[0084] According to some embodiments of this utility model, it can be referred to Figure 2 and Figure 3 The first end 101 of the buffer 10 is connected to the door 300. When the buffer 10 is not in failure, the sliding member 30 is limited by the first end 101 of the buffer 10, and the elastic member 40 and the detection member 20 are located on the upper side of the first end 101.

[0085] It should be noted that the end of the buffer 10 connected to the door 300 is subject to a higher frequency of friction, and the first end 101 of the buffer 10 is more prone to breakage. The first end of the buffer 10 is connected to the door 300. When the buffer 10 is not in failure, the slider 30 is limited by the first end 101 of the buffer 10. When the buffer 10 breaks, the first end of the buffer 10 will be pulled away from the door 300, and the slider 30 will be closer to the door 300. Therefore, the movement of the slider 30 is less likely to be interfered with by the buffer 10, which helps to increase the success rate of triggering the detection element 20 by the slider 30.

[0086] In the above technical solution, the elastic element 40 and the detection element 20 are located on the upper side of the first end 101. In this way, the elastic element 40 and the sliding element 30 will not occupy too much space on the lower side of the first end 101, which makes it easier to arrange the door anti-fall device 100 of the dishwasher.

[0087] According to some embodiments of this utility model, it can be referred to Figure 2 The buffer 10 includes a tension spring 102 and a pull rope 103 connected to each other to connect the door 300 and the machine body 200; when the buffer 10 is not in failure, the sliding member 30 is limited by the pull rope 103.

[0088] During the opening and closing of the door 300, the tension spring 102 of the buffer 10 deforms accordingly to drive the pull rope 103 to reciprocate. In other embodiments, the pull rope 103 may also have a certain elasticity, and its elastic deformation capacity is less than that of the tension spring 102. During the opening and closing of the door 300, the pull rope 103 also deforms accordingly.

[0089] Combination Figure 2 In one embodiment, one end of the tension spring 102 is connected to the body 200, one end of the pull rope 103 is connected to the other end of the tension spring 102, and the other end of the pull rope 103 is connected to the door 300. That is, the door 300 and the body 200 are connected by a combination of a tension spring 102 and a pull rope 103. In another embodiment, multiple tension springs 102 can be provided to connect the door 300 and the body 200 by a combination of multiple tension springs 102 and pull ropes 103. During the opening and closing of the door 300, the multiple tension springs 102 of the buffer 10 deform accordingly to drive the pull rope 103 to move.

[0090] According to some embodiments of this utility model, the dishwasher door anti-fall device 100 further includes a door lock assembly for locking the machine body 200 and the door 300. The detection element 20 and the door lock assembly are connected in series. When the detection unit 201 is not triggered, the detection element 20 is in a conductive state. The detection unit 201 is configured to switch to a disconnected state when a door anti-fall signal is received. Thus, when the buffer 10 fails, the dishwasher door anti-fall device 100 can prevent the door lock assembly from unlocking and prevent the door 300 from opening, thereby reducing the risk of the door 300 falling. For example, the detection element 20 can be a switch, such as a micro switch, which is relatively easy to implement and has low cost.

[0091] The second aspect of this utility model also proposes a dishwasher 1000.

[0092] You can refer to Figure 1 The dishwasher 1000 according to the second aspect of the present invention includes a body 200, a door 300, and a door anti-fall device 100 for the dishwasher according to any of the above embodiments.

[0093] Since the dishwasher 1000 according to the present invention includes a body 200, a door 300, and a door anti-fall device 100 of any of the above embodiments, the dishwasher 1000 of the present invention, by setting a detection element 20, a sliding element 30, and an elastic element 40, when the buffer element 10 is not in failure, the sliding element 30 is limited by the buffer element 10, so that the detection element 20 and the sliding element 30 are separated; when the buffer element 10 fails, the sliding element 30 moves to a set position under the pulling force of the elastic element 40 to trigger the detection unit 201, so that the detection unit 201 generates a door anti-fall signal. This helps the user to detect the failure of the buffer element 10 in time, reduces the risk of the door 300 falling after automatic opening, and reduces the possibility of accidents.

[0094] Furthermore, the elastic element 40 is used to apply tension to the sliding element 30. That is, when the buffer 10 is not in failure, the elastic element 40 is in a stretched state. In this way, there is no need to set a guide to limit the deformation of the elastic element 40. At the same time, the elastic element 40 in the stretched state can also adopt a simpler installation structure to achieve the connection with the sliding element 30 and the body 200. Therefore, it is beneficial to reduce the space occupied by the dishwasher door anti-fall device 100, so that the dishwasher door anti-fall device 100 of this application can better meet the arrangement requirements in a compact model.

[0095] For example, for a dishwasher, there may be at least two door anti-fall devices 100. For instance, there may be one dishwasher door anti-fall device 100 on the left side near the door 300 and one dishwasher door anti-fall device 100 on the right side near the door 300. The dishwasher door anti-fall devices 100 on both sides may be arranged symmetrically.
