Description

Draining pump cover for washing machine

Technical Field

The invention belongs to the technical field of washing machines, and particularly relates to a drainage pump cover for a washing machine.

Background

With the advancement of technology, the technology development of the washing machine industry has reached a relatively mature stage. However, for the ordinary users, the door lock of the washing machine cannot be opened due to the inevitable emergency. If a sudden power failure occurs in the working process of the drum washing machine, the machine door cannot be opened. The existing technology for solving the problems is to provide a door lock pull rope, one end of the door lock pull rope is connected with a door lock, one end of the door lock pull rope is placed in a drainage pump cover of a drum washing machine, when the condition that a machine door cannot be opened occurs, a user can open a drainage pump box cover to find the door lock pull rope, and the door lock pull rope is pulled downwards by hands to achieve the purpose of opening the door lock. But this solution is not applicable to exit drum washing machines with CB certification requirements. Because the IECEE electrical product test certificate mutual authentication system clearly requires that such designs meet the requirement that users cannot operate with both hands directly or only with tools to ensure safety. Therefore, it is necessary to design a new drain pump cover that can satisfy the certification and also enable the user to unlock the door lock by himself.

Disclosure of Invention

The invention aims to provide a draining pump cover for a washing machine, which can be used for facilitating a user to separate a placing hole on the draining pump cover from a draining pump box by means of a tool so as to take out a door lock pull rope, and opening a machine door of a drum washing machine in an emergency, thereby meeting the requirements of customers and safety certification.

In order to solve the technical problems, the invention is realized by the following technical scheme:

the invention relates to a draining pump cover for a washing machine, which comprises a draining pump cover body and a door lock pull rope, wherein edges are arranged on the periphery of the draining pump cover body; a boss is arranged on the upper surface of the drainage pump cover body close to the seamed edge; a key groove is formed in the boss, and a support rib is matched in the key groove in a clearance mode so that the door lock pull rope can be pulled conveniently on the premise of using a tool; one end of the support rib is connected with the drainage pump cover body, and the bottom surface of the support rib is provided with a connecting block vertical to the support rib; a placing hole is formed in the connecting block; one end of the bolt of the door lock pulling rope is placed in the placing hole.

Furthermore, the support rib comprises an upper plate and a side plate, and the upper plate and the side plate are connected in a right angle.

Furthermore, the through hole is formed in the position where the side plate is connected with the drainage pump cover body, so that the connection between the support rib and the drainage pump cover body is reduced, and the support rib is convenient to warp and break.

Further, the key slot is a T-shaped slot.

Further, the horizontal cross section of the key groove is rectangular or wedge-shaped or tenon-shaped or trapezoid-shaped.

Further, the connecting block is cylindrical or square.

Furthermore, the supporting ribs and the connecting blocks are integrated or combined.

The invention has the following beneficial effects:

according to the drainage pump cover, the placing hole in the drainage pump cover can be conveniently separated from the drainage pump box by a user through a tool, so that the door lock pull rope can be taken out, the machine door of the drum-type washing machine can be opened in an emergency, the requirements of customers can be met, and the safety certification can be met.

Of course, it is not necessary for any product in which the invention is practiced to achieve all of the above-described advantages at the same time.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "open," "upper," "lower," "one end," "top," "middle," "vertical," "inner," "around," and the like are used in an orientation or positional relationship that is merely for convenience in describing and simplifying the description, and do not indicate or imply that the referenced components or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be considered as limiting the present invention.

Referring to fig. 1 and 2, the drain pump cover of the washing machine of the present invention includes a drain pump cover body 1 and a door lock pull rope 104, wherein edges 105 are disposed around the drain pump cover body 1, a boss 108 is disposed on an upper surface of the drain pump cover body 1 near the edges 105, a bottom of the boss 108 is a hollow structure, a key groove 101 is disposed on the boss 108, a support rib 103 is disposed in the key groove 101 in a clearance fit manner, and a gap is left between the support rib 103 and the key groove 101, so that the door lock pull rope 104 is pulled under the premise of using a tool.

Referring to fig. 3, one end of the support rib 103 is connected to the drain pump cover body 1, and a connection block 106 perpendicular to the support rib 103 is disposed on the bottom surface of the support rib 103; the connecting block 106 is provided with a placing hole 102; the latch end of the door lock pull cord 104 is placed within the placement hole 102.

Preferably, the support rib 103 comprises an upper plate and a side plate, the upper plate and the side plate are connected at a right angle, and a through hole 107 is formed at a position where the side plate is connected with the drain pump cover body 1, so that the connection between the support rib 103 and the drain pump cover body 1 is reduced, and the support rib 103 is conveniently tilted and broken.

Preferably, the key groove 101 is a T-shaped groove, and the horizontal section of the key groove 101 is rectangular or wedge-shaped or tenon-shaped or trapezoid-shaped.

Preferably, the connecting block 106 is cylindrical or square, preferably cylindrical in this embodiment, and the supporting rib 103 and the connecting block 106 are integrated or combined, and if the connecting block 106 is combined, a groove is formed at the top end of the supporting rib 103, and a fixture block matched with the groove is formed at the bottom end of the supporting rib 103, so that the supporting rib 103 and the connecting block form a complete whole.

One specific application of this embodiment is: when emergency happens and the door of the drum washing machine is normally opened, the cover of the drainage pump box of the washing machine is firstly opened to expose the structure of the drainage pump cover. The tool is used for extending into the gap between the support rib 103 and the edge 105, and one end of the tool is propped against the joint of the support rib 103 and the placing hole 102 and prized outwards. The joint between the support rib 103 and the drain pump cover body 1 is thin, so it is easy to be broken. After the connecting portion is warped, the support rib 103 is separated from the drain pump cover body 1, and indirectly separates the placing hole 102 from the drain pump cover body 1, thereby taking out the door lock pulling rope 104. The bolt at one end of the door lock pull rope 104 is taken out of the placing hole 102, and the door lock pull rope 104 is pulled downwards to drive the door lock to be opened, so that the purpose of opening the machine door is achieved. After the door is opened, the door lock pull rope 104 is naturally drooped, and the drain pump cover is closed.
