Description
Technical field
The present invention relates to a kind of dish-washing machine, particularly relate to a kind of door lock assembly of dish-washing machine.
Background technology
In general, dish-washing machine is on a kind of tableware when utilizing washings to be ejected into top shelf and lower shelf, the household electrical appliance that tableware is washed.
Fig. 1 is the Facad structure schematic diagram of the door lock assembly of existing general dish washer; Fig. 2 is the structure schematic diagram of the door lock assembly of dish-washing machine shown in Figure 1.
As depicted in figs. 1 and 2, the door lock assembly of existing dish-washing machine is to install in the inner recess of dish washing machine door.
The door lock assembly of existing dish-washing machine comprises: latch shell 10 and latch 20; Described latch 20 is housed in latch shell 10 inside, and is connected with the bolt buckle on the front panel top that is formed on washing tube projectedly.
More particularly, described latch 20 comprises: latch fixture 21 and latch connector 22; Described latch fixture 21 is connected with the latch connector 22 that is positioned at its below; The front of described latch fixture 21 is formed with the bolt buckle mounting groove 27 that can insert described bolt buckle; Described latch fixture 21 is connected by hinges 26 with latch connector 22; Rotation mutually after described hinges 26 can make described latch fixture 21 be connected with latch connector 22, and its hinge axis is not fixed.
Be inserted in latch spring 23 on the outer peripheral face of described latch connector 22; The lower end of described latch connector 22 is formed with latch and connects hinge 24, connects hinge 24 by latch and is connected with latch shell 10.
Described latch shell 10 comprises: door connecting plate 15, bolt buckle insert mouth 11 and switch installation position 12; Described door connecting plate 15 is fixedly mounted on the back side of door; Described bolt buckle inserts mouth 11 and is formed on a connecting plate 15 central parts; Described switch installation position 12 is formed on the bottom of latch shell 10.
The back side of described latch shell 10 was formed with rotation and prevented plate 14, was used for preventing the excessive rotation of latch fixture 21; The lower end, the back side of described latch shell 10 is connected with door handle 30 by hinge.More particularly, the both sides of described latch shell 10 bottoms are formed with handle hinge openings 13, and handle hinge 33 usefulness run through described handle hinge openings 13, form hinge and be connected between the bottom of door handle 30 and latch shell 10; The central part of described handle hinge 33 is provided with handle spring 32, and when unclamping behind user's turn handle 30, described handle 30 can be returned to original position under the effect of handle spring 32.
In addition, be formed on the switch installation position 12 of described latch shell 10 bottoms door switch 40 is installed, protrude ground on the end face of described switch 40 and form contact terminal 41 is arranged; Protruding ground formation on the front panel of described door handle 30 has a pressing component 31 with certain-length, and described pressing component 31 is together adjacent with contact terminal 41; When the user upwards lifted door handle 30 in order to open the door, described pressing component 31 can be pressed into contact with on the terminal 41, and control device just receives the signal that a dish washing machine door is opened, and will carry out washing operation and end.
The shortcoming of the door lock assembly of above-mentioned existing dish-washing machine is: be in contact with one another with contact terminal 41 in order to make described pressing component 31, the upper end of described switch 40 forms hatch frame.
Like this, washings might flow in the latch shell 10 along latch fixture 21, the washings of inflow can be further along the inwall of latch connector 22 or latch shell 10 to dirty.And the washings that flow down can splash to the bottom of switch 40, thereby cause switch 40 impaired and can't operate as normal.
In addition, described switch 40 can generate heat, catch fire or leak current fault because of entering of washings.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of the door lock assembly of above-mentioned existing dish-washing machine, provides a kind of washings that prevent to flow to the door lock assembly of the dish-washing machine of switch.
