Embodiment 1

[0046] The door lock structure of this embodiment is used to lock any door body and box body, and this embodiment uses a sink type cleaning machine as an example for illustration. like Figure 11 As shown, the cleaning machine of this embodiment includes a box body 8 and a door body 9, the box body 8 has a washing chamber and an upper port 81 connected to the top of the washing chamber, and an edge of the door body 9 is connected to the upper port of the box body 8 by rotation. 81 at the edge.

[0047] The door lock structure used for electrical appliances in this embodiment includes a housing 1, a lock bar 2, an ejector 3, a lock catch 4, a second elastic member 20, a first elastic member 10, a limit block 5 and a driving mechanism, and the lock bar 2 Vertically installed on the lower wall of the door body 9 and arranged near the edge, the housing 1, the ejector 3, the first elastic member 10, the second elastic member 20, the lock 4, the limit block 5 and the driving mechan...

Embodiment 2

[0059] like Figures 12 to 16 As shown, the difference between this embodiment and the embodiment is:

[0060] The first elastic part of this embodiment is the first torsion spring 5', the first torsion spring 5' includes a middle helical body 51' and extension arms at both ends, the middle helical body 51' of the first torsion spring 5' is freely suspended and is located away from the lock On one side of the C-shaped opening of the buckle 4, the end of the first arm 52' of the first torsion spring 5' is connected to the outer edge 402 of the middle part of the buckle 4, and the end of the second arm 53' of the first torsion spring 5' is constrained in the on shell 1. When the upper end 420 of the C-shaped structure is located at the side of the ejector 3, the first torsion spring 5' keeps the buckle 4 in a clockwise direction around the shaft 41; the upper end 420 of the C-shaped structure is located above the ejector 3 and is aligned with When the locking hook 21 is engage...

Abstract

The invention relates to a door lock structure for an electric appliance and a cleaning machine applying the door lock structure. The door lock structure comprises a shell, a lock rod, an ejection piece, a lock catch and a driving mechanism, when a door body is closed, the ejection piece can be pressed downwards in an abutting mode, the ejection piece drives the lower end of the lock catch to movedownwards, the upper end of the lock catch of the C-shaped structure deflects towards the position above the ejection piece so as to be buckled with a C-shaped lock hook at the lower end of the lockrod, and self-locking of the door body is achieved; and the structure is realized by virtue of a mechanical structure, the requirement on electric control logic is low, the reliability is high, otherfunctions can be conveniently extended and designed on the basis of the invention, and the practicability is good.

Description

technical field [0001] The invention relates to a door lock structure for electrical appliances and a washing machine using the door lock structure. Background technique [0002] For a box with a functional inner cavity, due to functional requirements, a door that can open or cover the port is usually provided at the port of the box, and, during the use of the box, it is necessary to place the door relative to the The cabinet is locked. [0003] For example, the Chinese invention patent application "Door Switch Mechanism and Dishwasher with the Door Switch Mechanism" (application publication number: CN1550202A) with application number CN200410043122.5 discloses a structure, which includes: The tableware inlet is configured as a door that can be rotated, and a rotation assist mechanism that applies a rotation assist force to the door along with the rotation of the door; When the door is inside, the door is applied with a rotation assisting force in the direction of closing....
