[0034] A dishwasher is a household appliance that uses high-pressure water to clean dirty dishes. In related art, dishwashers perform washing, rinsing, and drying stages. During the drying stage, a fan system is typically used to expel hot, humid air from the dishwasher's interior, thereby achieving a drying effect. However, the humid environment within the washing chamber can prolong the drying process and reduce drying efficiency.

[0035] A washing appliance 200 according to an embodiment of the present application includes a cavity 10 , a door 20 and a hot air device 50 . The cavity 10 is formed with a washing cavity 14 and an opening 12 communicating with the washing cavity 14 . The door 20 is rotatably connected to the cavity 10 to close and open the opening 12 .

[0036] The hot air device 50 is disposed in the cavity 10 and is used to introduce heated air into the washing cavity 14 .

[0037] When the door body 20 is at a first opening, the hot air device 50 is in an open state to introduce heated gas into the washing chamber 14. When the door body 20 is at a second opening, the hot air device 50 is in a closed state. The second opening is greater than the first opening.

[0038] The above-mentioned washing appliance 200 associates the start and stop status of the hot air device 50 with the opening of the door body 20. When the door body 20 is at a first opening, the opening 12 of the door body 20 is small, and the hot air device 50 is in an open state, which is beneficial for the washing chamber 14 to discharge high-temperature moisture and improve the drying efficiency; when the door body 20 is at a second opening, the opening 12 of the door body 20 is large, and the hot air device 50 is in a closed state, and the washed items can be taken out of the washing chamber 14 to avoid the high-temperature gas in the washing chamber 14 from causing harm to the user.

[0039] Specifically, the body 10 of the washing appliance 200 is formed with a washing chamber 14 and an opening 12 communicating with the washing chamber 14. The door 20 is rotatably connected to the body 10 to close and open the opening 12. The washing appliance 200 primarily operates within the washing chamber 14, which contains a bowl basket 30 for placing items to be washed.

[0040] During the drying phase of the washing machine 200, the hot air device 50 begins operating, introducing heated, high-temperature air into the washing chamber 14. When the hot air device 50 begins operating, the door 20 of the washing machine 200 is opened to a first opening, allowing the hot air to pass through the opening 12 and expel the moist air from the washing chamber 14, thereby rapidly drying the items being washed.

[0041] During the drying phase, the washed items have been washed and rinsed and are now clean. Therefore, the user can remove the washed items and use them directly. When the user opens the door 20 to the second opening degree or greater, the hot air device 50 stops operating, allowing the user to remove the washed items from the washing chamber 14, preventing the high-temperature air in the washing chamber 14 from causing harm to the user.

[0042] The second opening is greater than the first opening. The specific values ​​of the first opening and the second opening can be set according to the structure and size of the washing device.

[0043] In some embodiments, the washing appliance 200 includes a trigger block 80 and a switch 70, the switch 70 is electrically connected to the hot air device 50, one end of the trigger block 80 is connected to the door body 20, and the other end of the trigger block 80 is connected to the cavity 10. When the door body 20 is at a first opening, the trigger block 80 is in a first position, the switch 70 is in a first state, and the hot air device 50 is in an open state. When the door body 20 is at a second opening, the trigger block 80 is in a second position, the switch 70 is in a second state, and the hot air device 50 is in a stopped state.

[0044] In this way, the door body 20 is connected via the trigger block 80 , and the change in the opening of the door body 20 drives the trigger block 80 to move, thereby changing the state of the switch member 70 .

[0045] Specifically, one end of the trigger block 80 is connected to the door body 20, and the other end of the trigger block 80 is connected to the cavity 10. The switch member 70 is electrically connected to the hot air device 50 and is used to control the start and stop state of the hot air device 50. When the opening of the door body 20 changes, the trigger block 80 is driven to switch between the first position and the second position. As shown in Figures 1, 4 and 5, when the door body 20 is at the first opening, the trigger block 80 is in the first position, the switch member 70 is in the first state, and the hot air device 50 is in the open state. As shown in Figures 2 and 3, when the door body 20 is at the second opening, the trigger block 80 is in the second position, the switch member 70 is in the second state, and the hot air device 50 is in the stopped state. By associating the trigger block 80 with the opening of the door body 20, the change in the opening of the door body 20 drives the position switching of the trigger block 80, triggering the switch member 70 to switch the start and stop state of the hot air device 50.

[0046] It can be understood that the first state of the switch component 70 can be an untriggered state. When the switch component 70 is in the first state, the hot air device 50 is in the on state. The second state of the switch component 70 can be a triggered state. The switch component 70 can trigger the hot air device 50 to switch it to a stopped state.

[0047] Alternatively, the first state of the switch component 70 can be a triggered state. When the switch component 70 is in the first state, the switch component 70 can trigger the hot air device 50 to switch it to the on state. The second state of the switch component 70 can be an untriggered state. When the switch component 70 is in the second state, the switch component 70 switches from the triggered state to the untriggered state, so that the hot air device 50 is in the stopped state.

[0048] Optionally, the switch member 70 includes a micro switch.

[0049] In some embodiments, the trigger block 80 includes a first section and a second section, the first section is connected to the second section, the switch member 70 includes a housing and a detection portion, the detection portion is connected to the housing, when the trigger block 80 is in the first position, the first section is spaced apart from the detection portion, and when the trigger block 80 is in the second position, the second section contacts the detection portion.

[0050] In this way, after the trigger block 80 is driven by the door body 20 , it contacts and triggers the switch member 70 , thereby realizing opening or closing the hot air device 50 .

[0051] Specifically, the trigger block 80 includes a first section and a second section, with the first section connecting to the second section and having a thickness smaller than that of the second section. The door 20 drives the trigger block 80 to switch between the first and second positions. In the first position, the first section of the trigger block 80 does not contact the switch 70. In the second position, the second section of the trigger block 80 is thicker and contacts the detection portion of the switch 70, thereby triggering the switch 70 and changing its state.

[0052] In some embodiments, the length of the second segment is positively correlated with the opening range of the second opening.

[0053] In this way, the opening of the door body 20 corresponding to when the hot air device 50 is turned on and off can be adjusted by adjusting the lengths of the first section and the second section of the trigger block 80 .

[0054] Specifically, as shown in Figure 3, the switch member 70 and the trigger block 80 are arranged in a vertical direction, and the thickness of the first section of the trigger block 80 is less than the thickness of the second section. When the door 20 is at a first opening, the first section does not contact the switch member 70. When the door 20 switches from the first opening to the second opening, the trigger block 80 moves with the door 20, and the second section gradually approaches the detection portion of the switch member 70. Until the door 20 reaches the second opening, the second section contacts the detection portion, causing the hot air device 50 to stop supplying hot air into the washing chamber 14.

[0055] When the door 20 is at a first opening, the area of ​​communication between the opening 12 and the exterior of the washing chamber 14 is small. The hot air device 50 introduces heated air into the washing chamber 14 to dry the washed items therein. The moist air is then exhausted from the opening 12, thereby accelerating the drying process and improving drying efficiency. When the door 20 is at a second opening, the area of ​​communication between the opening 12 and the exterior of the washing chamber 14 is larger, making it easier for the user to remove washed items from the washing chamber 14.

[0056] During the drying phase, when the door 20 opening is less than the second opening, the hot air device 50 is in the open state. When the door 20 opening is equal to or greater than the second opening, the hot air device 50 stops operating. The second opening is the opening at which the user can remove the washed items from the opening 12. By adjusting the length of the first and second sections of the trigger block 80, the corresponding opening of the door 20 when the hot air device 50 is turned on and off can be adjusted. For washing appliances 200 of different sizes or door 20 structures, the length of the first and second sections of the trigger block 80 can also be adjusted to achieve the corresponding start and stop states of the hot air device 50 at different door 20 openings.

[0057] In some embodiments, the housing defines a first mounting hole, the cavity 10 defines a second mounting hole, and the switch member 70 includes a fastener that passes through the first mounting hole and the second mounting hole to securely mount the housing in the cavity 10 .

[0058] In this way, the switch member 70 is fixed to the cavity 10 by fasteners, and the installation is simple and convenient.

[0059] Specifically, the housing defines a first mounting hole, and the cavity 10 defines a second mounting hole. Fasteners pass through the first and second mounting holes to secure the housing to the cavity 10. Using fasteners to secure the switch element 70 is simple, convenient, and provides a secure and reliable connection. Furthermore, most fasteners are standard parts, making them easy to manufacture, process, or purchase, thereby reducing costs.

[0060] It should be noted that fasteners include but are not limited to bolts, rivets, pins or other types of fasteners.

[0061] In some embodiments, the washing appliance 200 includes a transmission member, one end of which is connected to the door body 20, and the other end of the transmission member is connected to the trigger block 80. The transmission member is used to drive the trigger block 80 to move when the door body 20 switches between the first opening and the second opening so that the trigger block 80 switches between the first position and the second position.

[0062] In this way, the trigger block 80 can be arranged in the limited space of the cavity 10 , so that the trigger block 80 triggers the switch member 70 to control the start and stop state of the hot air device 50 .

[0063] Specifically, the door body 20 is rotatably connected to the cavity 10, with one end of the transmission member connected to the door body 20 and the other end connected to the trigger block 80. In the illustrated embodiment, as shown in Figures 1, 2, and 3, the door body 20 rotates around one side of the cavity 10, driving the transmission member to move up and down, and the transmission member drives the trigger block 80 to move back and forth, thereby switching the trigger block 80 between the first position and the second position. In this way, by connecting the door body 20 and the trigger block 80 through the transmission member and switching the direction of movement, the trigger block 80 can be arranged in the limited space of the cavity 10, so that the trigger block 80 can trigger the switch member 70 to control the start and stop state of the hot air device 50.

[0064] In some embodiments, the cavity 10 defines a mounting groove, and the transmission member is installed in the mounting groove.

[0065] In this way, the mounting groove can be used to protect the transmission member, while at the same time ensuring that the size of the washing appliance 200 in the left-right direction does not increase after the transmission member is added.

[0066] Specifically, the transmission member is mounted in the mounting slot and is movable within the mounting slot. The mounting slot protects the transmission member from damage that could cause it to lose its transmission function. Furthermore, the mounting slot ensures that the addition of the transmission member to the washing appliance 200 maintains the left-right dimensions of the washing appliance 200, thereby maintaining the overall dimensions of the washing appliance 200.

[0067] In some embodiments, the washing appliance 200 further includes an elastic member 60 , one end of the elastic member 60 is connected to the door 20 , and the other end of the elastic member 60 is connected to the cavity 10 , so that the door 20 tends to move toward the cavity 10 .

[0068] In this way, the elastic member 60 can quickly restore the door body 20 to the state of closing the opening 12 .

[0069] Specifically, one end of the elastic member 60 is connected to the door body 20, and the other end of the elastic member 60 is connected to the cavity 10. When the door body 20 rotates away from the cavity 10, the elastic member 60 is stretched, causing the door body 20 to tend to move toward the cavity 10. When the component force of the door body 20 in the direction of gravity is greater than the restoring force of the elastic member 60, the door body 20 remains open. When the component force of the door body 20 in the direction of gravity is less than the restoring force of the elastic member 60, or when an external force in the same direction as the restoring force of the elastic member 60 is applied to the door body 20, the door body 20 can quickly return to the state of closing the opening 12 without the need for continued external force, as shown in Figures 2 and 4. This makes it easier for the user to close the door body 20.

[0070] In the illustrated embodiment, one end of the transmission member is connected to the door body 20, and the other end is connected to the trigger block 80, which is then connected to the elastic member 60 through the trigger block 80. The movement direction of the trigger block 80 is consistent with the deformation direction of the elastic member 60. Through this connection method, the connection between the door body 20, the transmission member, the trigger block 80 and the elastic member 60 can be simply and reliably achieved.

[0071] In some embodiments, the washing appliance 200 further includes a door opening device 100, which is disposed in the cavity 10. The door opening device 100 includes a driving member and a pushing member. The driving member is connected to the pushing member, and the driving member is used to drive the pushing member to extend to push the door body 20 to a first opening.

[0072] In this way, when the washing appliance 200 begins to enter the drying stage, the door 20 is automatically opened to the first degree.

[0073] Specifically, as shown in Figure 1, the door opening device 100 is disposed at the top of the cavity 10. The driving member is used to drive the pusher to extend and retract. When the pusher is extended, the pusher contacts and pushes the door body 20 to rotate, so that the door body 20 is at a first opening. The driving member can be electrically connected to the controller of the washing appliance 200, so that when the washing appliance 200 enters the drying stage, the pusher is driven to extend to open the door body 20 to the first opening.

[0074] Optionally, the door opening device 100 includes a push rod motor.

[0075] In some embodiments, the washing appliance 200 includes a hinge 40 , and the door 20 is rotatably connected to the cavity 10 via the hinge 40 .

[0076] In this way, the door body 20 can be rotatably connected to the cavity body 10 .

[0077] Specifically, as shown in Figures 1 and 4, the door body 20 is connected to the cavity 10 by rotating through the hinge 40, so that the door body 20 can be opened to any opening. Connecting the door body 20 and the cavity 10 through the hinge 40 requires fewer parts for installation, has a simple structure, is convenient to install, and is low in cost.

[0078] In some embodiments, the washing machine 200 includes a door detector 90 disposed at the top of the cavity 10 for detecting whether the door 20 is in a closed state with the opening 12. The washing machine 200 can only perform the washing and rinsing steps when the door 20 is in a closed state with the opening 12.

[0079] Optionally, the door detection member 90 includes a micro switch.

[0080] To sum up, the start and stop status of the hot air device 50 of the washing appliance 200 is associated with the opening of the door body 20. When the door body 20 is at a first opening, the opening 12 of the door body 20 is small, and the hot air device 50 is in an open state, which is beneficial for the washing chamber 14 to discharge high-temperature moisture and improve the drying efficiency; when the door body 20 is at a second opening, the opening 12 of the door body 20 is large, and the hot air device 50 is in a closed state, and the washed items can be taken out of the washing chamber 14 to avoid the high-temperature gas in the washing chamber 14 from causing harm to the user.
