Description

Technical Field

[0001] This invention relates to the field of dishwashers, and more specifically, to a dishwasher. Background Technology

[0002] Currently, most dishwashers are manually operated and have low levels of automation. When users approach the dishwasher with a pile of used dishes, they need to put the dishes aside, open the dishwasher door, and then place the dishes in, which is inconvenient. If the user's hands are oily while collecting or moving the dishes, the door handle will get dirty when they try to open the dishwasher door.

[0003] In existing technology, there is a method for controlling the opening and closing of a dishwasher lid. The lid opens or closes via a drive mechanism. After the washing cycle of the sink-type washer is completed, the temperature inside the sink is detected. When the temperature reaches a first preset temperature value, the drive mechanism is controlled to open the lid for heat dissipation and cooling. The lid remains open for a certain period of time, and the temperature inside the sink is continuously monitored. When the detected temperature drops to a second preset temperature value, the drive mechanism is controlled to close the lid. By controlling the opening and closing time and angle of the lid, water vapor inside the washer can be promptly discharged after the washing cycle, accelerating the drying speed of dishes and the washer itself. Furthermore, the automatic control eliminates the need for manual operation by the user, improving safety.

[0004] However, the aforementioned automatic door opening and closing solution for dishwashers has the following drawbacks: it cannot open the door to 90°; when the door is opened to its maximum angle, the push rod is exposed, which obstructs the loading and unloading of dishes; during a power outage, the push rod cannot extend or retract, and the door cannot be opened; if the user ignores the automatic door and tries to push or pull it by hand, the door will not move. If the user applies even slightly excessive force, there is a risk of damaging the machine's structure. Summary of the Invention

[0005] The main objective of this invention is to provide a dishwasher that solves the problem that existing dishwashers cannot be compatible with both manual and automatic door opening / closing functions.

[0006] To achieve the above objectives, the present invention provides a dishwasher, comprising an inner tub, a door component, and a drive mechanism. The inner tub has an operating opening; the door component is connected to the inner tub and has a closed position for closing the operating opening and an open position for opening the operating opening; the drive mechanism includes: a drive member connected to the door component to switch the door component between the closed position and the open position under the drive of the drive member; and a linkage limiting assembly connected to the drive member, which, when the door component is opened or closed, switches the door component between the closed position and the open position under the action of the linkage limiting assembly and the drive member.

[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0031] This invention provides a dishwasher, please refer to... Figures 1 to 6 The device includes an inner liner 10, a door component 20, and a drive mechanism 30. The inner liner 10 has an operating port 11. The door component 20 is connected to the inner liner 10 and has a closed position that closes the operating port 11 and an open position that opens the operating port 11. The drive mechanism 30 includes: a drive member 31 connected to the door component 20 to switch the door component 20 between the closed and open positions under the drive of the drive member 31; and a linkage limiting assembly 32 connected to the drive member 31, which switches the door component 20 between the closed and open positions under the action of the linkage limiting assembly 32 and the drive member 31 when the door component 20 is opened or closed.

[0032] The dishwasher of the present invention includes an inner tub 10, a door component 20, and a drive mechanism 30. The door component 20 is closable and can switch between a closed position and an open position to open or close the operating opening 11 for loading and unloading tableware. The drive mechanism 30 includes a drive element 31 and a connecting rod limiting assembly 32. The drive element 31 can drive the door component 20 to switch between a closed position and an open position to achieve automatic opening and closing of the door component 20. When it is necessary to manually open or close the door component 20, the drive element 31 is not powered, and the door component 20 switches between the closed position and the open position under the mechanical connection of the connecting rod limiting assembly 32 and the drive element 31. This dishwasher has both automatic door opening and closing functions and can also be manually opened and closed by pushing and pulling.

[0033] In this embodiment, the linkage limiting assembly 32 includes a linkage 321, one end of which is connected to the inner liner 10 and rotatably disposed relative to the inner liner 10, and the other end of which is connected to the end of the drive member 31 away from the door body component 20 and rotatably disposed relative to the drive member 31.

[0034] In this embodiment, the connecting rod 321 has a groove 322; the connecting rod limiting assembly 32 further includes: a first gas spring 323, one end of which is connected to the inner liner 10 and rotatably disposed relative to the inner liner 10; a sliding part 324 is provided on the other end of the first gas spring 323, the sliding part 324 is adapted to the groove 322, and the sliding part 324 is slidably disposed along the groove 322; and a second gas spring 325, which is located on the side of the connecting rod 321 away from the first gas spring 323, one end of which is fixedly connected to the inner liner 10, and the other end of which abuts against the connecting rod 321.

[0035] Specifically, the sliding part 324 is a pin, and the first gas spring 323 is connected to the connecting rod 321 via the pin and the second retaining ring 330. The pin is inserted into the slide groove 322 and the third connecting hole 329 of the first gas spring 323, and slides along the extension direction of the slide groove 322. The extension direction of the slide groove 322 is the same as the extension direction of the connecting rod 321.

[0036] Specifically, the end of the connecting rod 321 connected to the drive member 31 is located above the end of the connecting rod 321 connected to the third mounting plate 36.

[0037] Specifically, the first gas spring 323 includes a first gas spring outer rod and a first gas spring inner rod. The first gas spring inner rod is inserted into the first gas spring outer rod and is telescopically arranged relative to the first gas spring outer rod. The first gas spring outer rod is connected to the second mounting plate 35, and the first gas spring inner rod is connected to the connecting rod 321.

[0038] Specifically, the second gas spring 325 includes a second gas spring outer rod and a second gas spring inner rod. The second gas spring inner rod is inserted into the second gas spring outer rod and is telescopically arranged relative to the second gas spring outer rod. The second gas spring outer rod is connected to the inner liner.

[0039] In this embodiment, the connecting rod limiting assembly 32 further includes a slider 326, which is fixedly disposed at one end of the second gas spring 325 near the connecting rod 321. The slider 326 is used to abut against the connecting rod 321.

[0040] Specifically, the slider 326 is connected to the second gas spring 325 via the second pin 332 and the fifth retaining ring 333. The slider 326 has a limiting groove, and one end of the second gas spring 325 has a limiting part that matches the limiting groove. The limiting part is engaged within the limiting groove to restrict the slider 326 from rotating relative to the second gas spring 325. This arrangement restricts the slider 326 from rotating around the second pin 332, thus achieving a fixed connection between the slider 326 and the second gas spring 325.

[0041] In this embodiment, the drive mechanism 30 further includes a connecting part 33, one end of which is fixedly connected to the door component 20, and the other end of which is hinged to the drive member 31.

[0042] In this embodiment, the driving component 31 includes a driving body 311 and a telescopic rod 312. The telescopic rod 312 is inserted into the driving body 311 and is telescopically arranged relative to the driving body 311. The end of the telescopic rod 312 away from the driving body 311 is hinged to the connecting part 33. The end of the driving body 311 away from the telescopic rod 312 is connected to the connecting rod limiting component 32.

[0043] Specifically, the drive body 311 is connected to the connecting rod 321 via a first pin 314 and a first retaining ring 315. The first pin 314 is inserted into the first connecting hole 313 of the drive body 311 and the second connecting hole 327 of the connecting rod 321. There are two second connecting holes 327, which are arranged opposite each other on opposite sides of the first connecting hole 313. This arrangement allows the drive body 311 and the connecting rod 321 to be rotatably mounted relative to each other, while preventing relative movement between them along the axial direction of the first pin 314.

[0044] Specifically, the telescopic rod 312 is connected to the connecting part 33 via a seventh snap ring and a fourth pin.

[0045] Preferably, the driving component 31 is an electric push rod.

[0046] In this embodiment, the dishwasher includes a base 40 and a rear beam 50, with an inner liner 10 disposed on the base 40 and connected to the rear beam 50; the drive mechanism 30 further includes a first mounting plate 34, which is connected to both the base 40 and the rear beam 50, and a second gas spring 325 fixedly connected to the first mounting plate 34.

[0047] Specifically, the first mounting plate 34 is fixedly mounted on the base 40 and the rear beam 50; the second gas spring 325 is connected to the first mounting plate 34 via a third pin 342 and a sixth retaining ring 343. The third pin 342 extends horizontally; the first mounting plate 34 has two limiting plates 341, which are vertically positioned on opposite sides of the second gas spring 325 to restrict its rotation. This arrangement restricts the second gas spring 325 from rotating around the third pin 342, thus achieving a fixed connection between the second gas spring 325 and the first mounting plate 34.

[0048] In this embodiment, the drive mechanism 30 further includes: a second mounting plate 35, which is disposed on the outer wall of the inner liner 10, and a first gas spring 323 connected to the second mounting plate 35 and rotatably disposed relative to the second mounting plate 35.

[0049] Specifically, the second mounting plate 35 is fixed on the outer wall of the inner liner 10; the first gas spring 323 is connected to the second mounting plate 35 through the first mounting shaft 351 and the third retaining ring 352; the first mounting shaft 351 is fixedly connected to the second mounting plate 35, and the first mounting shaft 351 is inserted into the fourth connecting hole 331 of the first gas spring 323.

[0050] In this embodiment, the drive mechanism 30 further includes a third mounting plate 36, which is disposed on the outer wall of the inner liner 10, and a connecting rod 321 is connected to the third mounting plate 36 and is rotatably disposed relative to the third mounting plate 36.

[0051] Specifically, the third mounting plate 36 is fixed to the outer wall of the inner liner 10; the connecting rod 321 is connected to the third mounting plate 36 via the second mounting shaft 361 and the fourth retaining ring 362; the second mounting shaft 361 is fixedly connected to the third mounting plate 36, and the second mounting shaft 361 is inserted into the fifth connecting hole 328 of the connecting rod 321.

[0052] In this embodiment, the door component 20 is located on the front side of the inner liner 10; there are two drive mechanisms 30, which are arranged on opposite sides of the inner liner 10. The front side of the inner liner 10 is the front of the dishwasher, and the two drive mechanisms 30 are arranged on opposite sides of the door component 20. Both door components 20 are connected to the outer side wall of the inner liner 10.

[0053] Preferably, the two drive mechanisms 30 are symmetrically arranged on the left and right sides of the inner liner 10; that is, the two drive mechanisms 30 are arranged on opposite sides of the inner liner 10 in the horizontal direction; or, the two drive mechanisms 30 are arranged on opposite sides of the door body component 20 in the horizontal direction.

[0054] In this embodiment, the dishwasher includes a limiting member disposed on the base 40 of the dishwasher, which is used to limit the door component 20 to the open position.

[0055] In this embodiment, the dishwasher includes a control system, which includes a current monitoring module connected to the drive component 31 to monitor the current of the drive component 31. When the door component 20 is in the open or closed position, the door component 20 cannot continue to move, and at this time, the current in the drive component 31 increases. When the current monitoring module detects that the current in the drive component 31 reaches a preset current, it stops supplying power to the drive component 31, and the drive component 31 stops moving, completing and ending an automatic door opening or closing action. The control system is a control circuit board, and the current monitoring module is a part of the circuit in the control circuit board. The current monitoring module and the drive component 31 form a circuit loop.

[0056] In specific implementation, such as Figure 4 As shown, under normal use, the first and second gas springs are in their natural state, at which point their lengths are at their maximum. The first and second gas springs press against the connecting rod 321 from two directions, preventing it from rotating. Each gas spring has a rated pressure; when the pressure exerted by the connecting rod 321 on the first and second gas springs is less than their rated pressures, the first and second gas springs will not be compressed.

[0057] In specific implementation, when the drive component 31 (i.e., the electric push rod) is energized and the drive component 31 extends, the connecting rod 321 cannot rotate under the support of the first and second gas springs. The first connecting hole 313 of the drive component 31 remains fixed, and the end of the telescopic rod 312 away from the drive body 311 is pushed downward. Under the action of the connecting part 33, the first connecting hole 313 and the connecting part 33 of the drive component 31 rotate counterclockwise along the rotation axis of the door component, and the door component realizes the automatic closing process (i.e., moving from the open position to the closed position).

[0058] In specific implementation, when the drive component 31 (i.e., the electric push rod) is energized and the drive component 31 is shortened, the connecting rod 321 cannot rotate under the support of the first and second gas springs. The first connecting hole 313 of the drive component 31 remains fixed, and the end of the telescopic rod 312 away from the drive body 311 is pulled upward. Under the action of the connecting part 33, the first connecting hole 313 and the connecting part 33 of the drive component 31 rotate clockwise along the rotation axis of the door component, and the door component realizes the automatic opening process (i.e., moving from the closed position to the open position).

[0059] In practical implementation, under abnormal circumstances (power outage or manual pushing / pulling of the door during automatic opening / closing), when the door component 20 is manually pulled open, if the length of the driving component 31 remains unchanged or the speed at which it shortens is less than the speed at which the door is manually pulled open, the connecting part 33 applies an upward force to the driving component 31. The driving component 31 then applies a counter-clockwise rotational torque to the connecting rod 321. When the rated pressure of the second gas spring is insufficient to hold the connecting rod 321, the connecting rod 321 rotates counter-clockwise, the driving component 31 moves upward, and the door component 20 is manually pulled open. Figure 5 As shown. When the manual pulling force is removed, the connecting rod 321 rotates clockwise under the thrust of the second gas spring, returning to its original position. Figure 4 As shown in the starting position, the position of the door component 20 will also return to the matching position according to the length of the drive component 31. It should be noted that if the door is manually pulled during the automatic opening process, the door component 20 will eventually move to the open position; if the door is manually pulled after a power outage, a continuous pulling force needs to be applied to the door component 20 to ensure that the door component 20 remains in the open position. After this pulling force is removed, the door component 20 will return to the position where the door component 20 was when the power outage occurred.

[0060] In practical implementation, under abnormal circumstances (power outage or manual pushing / pulling of the door during automatic opening / closing), when the door component 20 is manually pushed to close, and the length of the driving member 31 remains unchanged or its extension speed is less than the speed at which the door is manually pushed, the connecting part 33 applies a downward force to the driving member 31, which in turn applies a clockwise rotational torque to the connecting rod 321. When the rated pressure of the first gas spring is insufficient to hold the connecting rod 321, the connecting rod 321 rotates clockwise, the driving member 31 moves downward, and the door component is manually pushed closed. Figure 6 As shown. When the manual thrust is removed, linkage 321 rotates counterclockwise again under the thrust of the first gas spring, returning to its original position. Figure 4As shown in the starting position, the position of the door component 20 will also return to the matching position according to the length of the drive component 31. It should be noted that if the door is manually pushed during the automatic closing process, the door component 20 will eventually move to the closed position; if the door is manually pushed after a power outage, a continuous pushing force needs to be applied to the door component 20 to ensure that the door component 20 is in the closed position. After this pushing force is removed, the door component 20 will return to the position where the door component 20 was when the power outage occurred.

[0061] The dishwasher described in this application solves the following technical problems: low level of automation in manual door opening and closing; inconvenience for users holding tableware when pushing or pulling the door; dirtying the door handle when the user's hands are oily from the tableware; inability to open the door to 90°; when the door is opened to its maximum angle, the push rod is exposed, obstructing the loading and unloading of tableware; the push rod cannot extend or retract during a power outage, preventing the door from opening; and the door cannot move when the user ignores it and tries to push or pull it manually. Furthermore, there is a risk of damaging the machine's structure if the user applies even slightly excessive force.

[0062] The dishwasher described in this application offers the following advantages: It features a high degree of intelligent automatic door opening and closing; users do not need to manually push or pull the door while holding tableware; it prevents users from soiling the dishwasher door if their hands are greasy with tableware; and it can also be opened and closed manually by pushing or pulling the door. Furthermore, the dishwasher door component can open 90°, with a large range between the open and closed positions; when the door component 20 is opened to its maximum angle, except for the connecting part 33 at the lower end of the door component, all other components of the drive mechanism 30 are not exposed, ensuring unobstructed loading and unloading of food. Simultaneously, this dishwasher also solves the following problems: during a power outage, the push rod cannot extend or retract, preventing the door from opening; when the user ignores the automatic door and tries to push or pull it manually, the door cannot move. If the user applies even slightly excessive force, there is a risk of damaging the machine's structure.

[0063] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0064] The dishwasher of the present invention includes an inner tub 10, a door component 20, and a drive mechanism 30. The door component 20 is closable and can switch between a closed position and an open position to open or close the operating opening 11 for loading and unloading tableware. The drive mechanism 30 includes a drive element 31 and a connecting rod limiting assembly 32. The drive element 31 can drive the door component 20 to switch between a closed position and an open position to achieve automatic opening and closing of the door component 20. When it is necessary to manually open or close the door component 20, the drive element 31 is not powered, and the door component 20 switches between the closed position and the open position under the mechanical connection of the connecting rod limiting assembly 32 and the drive element 31. This dishwasher has both automatic door opening and closing functions and can also be manually opened and closed by pushing and pulling.
