Therefore, the present application is not limited to the specific embodiments disclosed below.
[0034] First embodiment:
[0035] See Figures 1-5 A door pop-out mechanism includes an elastic push rod 3 that is elastically telescopically movable between a body 1 and a door 2;
[0036] One end of the elastic push rod 3 acts elastically on the door 2. When the door 2 is in the unlocked state, it is elastically opened on the machine body 1 by the elastic push rod 3, so that the door 2 can automatically pop out and open when it is in the unlocked state.
[0037] By setting a door pop-out mechanism, after door 2 is unlocked, the elastic push rod 3 pops door 2 out, so that door 2 automatically opens on the machine body 1 after unlocking. After door 2 is unlocked, the user can open door 2 without manually pulling it open, which is convenient and improves the user's experience with the machine body 1.
[0038] The elastic push rod 3 is located at the opening / closing position 4 between the machine body 1 and the door body 2.
[0039] The door pop-out mechanism also includes a housing 6 that cooperates with the elastic push rod 3. The housing 6 is provided with a mounting cavity 7 for installing the elastic push rod 3. An elastic element 8 is provided between the elastic push rod 3 and the housing 6. The elastic push rod 3 is elastically extended and retracted on the housing 6 through the elastic element 8.
[0040] In this embodiment, the body 1 includes a top frame 14, and the housing 6 is fixed to the top frame 14 by screws. The front end of the top frame 14 is provided with a through hole corresponding to the elastic extension end of the elastic push rod 3.
[0041] In this embodiment, one end of the elastic push rod 3 is provided with a receiving cavity for installing the elastic element 8. One end of the elastic element 8 acts elastically on the receiving cavity of the elastic push rod 3, and the other end of the elastic element 8 acts elastically on the bottom wall of the mounting cavity 7 of the housing 6.
[0042] Door 2 closes and locks onto the machine body. Door 2 presses against the elastic push rod 3, and the elastic element 8 is in a compressed state. When door 2 is in the unlocked state, the elastic push rod 3 is elastically pushed out by the elastic force released by the elastic element 8. When the elastic push rod 3 is elastically pushed out, it pushes the door 2 to elastically open the door 2 onto the machine body 1.
[0043] The housing 6 is provided with a limiting block 9 corresponding to the telescopic displacement of the elastic push rod 3. The elastic push rod 3 is limited to telescopically mounted on the housing 6 by the limiting block 9.
[0044] The elastic push rod 3 is provided with a fastening member 10 that forms a limiting engagement with the limiting block 9. The fastening member 10 and the limiting block 9 form an anti-detachment structure to prevent the elastic push rod 3 from detaching from the housing 6.
[0045] During the elastic push-rod process, the limiting block 9 and the fastening part 10 cooperate to prevent the elastic push-rod 3 from detaching from the housing 6.
[0046] In this embodiment, the fastening member 10 protrudes from the side of the elastic push rod 3.
[0047] The elastic push rod 3 and the housing 6 are provided with a sliding connection fitting part to prevent them from rotating relative to each other. The elastic push rod 3 and the housing 6 are movably connected through the sliding connection fitting part.
[0048] The elastic push rod 3 is provided with a fastening element 10, and the housing 6 is provided with a sliding fastening groove 11 that cooperates with the fastening element 10. The fastening element 10 and the sliding fastening groove 11 cooperate to form a sliding connection and fit part, so that the elastic push rod 3 and the housing 6 are movably connected. During the elastic extension and retraction axial movement of the elastic push rod 3, the fastening element 10 is limited to move on the sliding fastening groove 11.
[0049] During the elastic extension and retraction of the elastic push rod 3, the fastening part 10 is positioned on the upper and lower limits of the sliding fastening groove 11. This prevents relative rotation between the elastic push rod 3 and the housing 6, and enables a sliding connection between the elastic push rod 3 and the housing 6.
[0050] The fastening member 10 is provided with a guide slope 13 for guiding the elastic push rod 3 to be installed at the corresponding position on the housing 6.
[0051] In this embodiment, the sliding fastening groove 11 extends through both sides of the housing 6 and connects to the mounting cavity 7 of the housing 6. The elastic push rod 3 is inserted into the mounting cavity 7 of the housing 6. The elastic push rod 3 is pushed into the mounting cavity 7 of the housing 6 by the guide slope 13 of the fastening member 10. The fastening member 10 undergoes elastic deformation. When the fastening member 10 moves to the sliding fastening groove 11, the fastening member 10 elastically resets and enters the sliding fastening groove 11.
[0052] The housing 6 is provided with a fixing part 12 for fixing to the corresponding body parts.
[0053] In this embodiment, the fixing part 12 is a screw hole.
[0054] The elastic push rod 3 is made of a flexible material, or the end of the elastic push rod 3 corresponding to the elastic push door 2 is provided with a soft buffer for anti-collision. During the opening and closing process, when the door 2 comes into contact with the elastic push rod 3, the soft buffer effectively absorbs the corresponding impact force, avoiding the door 2 from generating a large noise during the opening and closing process.
[0055] In this embodiment, the body 1 is provided with a lock seat, and the door 2 is provided with a motor and a slider connected to the motor's telescopic drive shaft. The slider is provided with an inclined surface that acts on the latch, and the bottom of the latch is provided with a compression spring. When the drive shaft drives the slider to move in the direction of squeezing the compression spring, the slider presses down on the latch through the inclined surface, causing the latch to disengage from the lock seat, and the door 2 is in the unlocked state. When the drive shaft resets, the slider resets, and the latch is elastically reset to the locked position, realizing the locking engagement between the latch and the lock seat.
[0056] A household appliance includes a body 1 and a door 2 that opens and closes on the body 1, wherein the aforementioned door pop-out mechanism is provided between the body 1 and the door 2;
