TECHNICAL FIELD
[0001] The utility model relates to a bowl cleaning equipment, especially to a structure for preventing children from opening the lock of a dishwasher. BACKGROUND
[0002] A dishwasher is an intelligent household appliance that can automatically clean and flush dishes. Users only need to simply put the dishes into the dishwasher, select the appropriate dishwashing program, and then start the dishwasher to easily complete the dishwashing task. The door design of the dishwasher ensures its sealing performance during operation.
[0003] Most dishwashers are equipped with a heating function in the washing mode, and the washing water can be heated to a high temperature of 70-80℃. Such hot water at high temperature poses a risk of scalding to human skin. Especially during the operation of the dishwasher, if a child unknowingly opens the door, the washing hot water may be instantly sprayed, which is extremely easy to cause scalding accidents.
[0004] Therefore, many improved documents in this regard are disclosed in the prior art, and the Chinese invention patent application for "child lock device of dishwasher door cover and dishwasher" (application publication number CN108714017A) with application number 201810907011.6 can be referred to. The dishwasher in this application includes a dishwasher tank and a door cover arranged on the top of the dishwasher tank. A strong magnetic switch is arranged on the door cover, and the strong magnetic switch is connected to the main circuit. A magnetic sheet is arranged on the dishwasher tank at a position corresponding to the strong magnetic switch. The main circuit controls the power-on or power-off of the strong magnetic switch. When powered on, the strong magnetic switch generates strong magnetism and is attracted to the magnetic sheet. The door cover is locked to prevent the door cover from being opened due to misoperation. When powered off, the magnetism of the strong magnetic switch is lost, and the door cover can be opened.
[0005] The Chinese utility model patent "child lock mechanism and dishwasher" (authorized publication number CN213429948U) with patent number ZL202021439125.1 can also be referred to. The child lock mechanism in this patent includes a door handle and a locking mechanism. The locking mechanism is connected to the door handle and arranged on the inner and outer sides of the door body, respectively. The locking mechanism can make the door body form an openable or lockable state when the door handle is pulled upward or downward. When a child opens the door, the locking mechanism can lock the door body when the door handle is pulled downward, thereby preventing the child from opening the dishwasher door body by himself / herself and avoiding the washing hot water in the working dishwasher from scalding the child.

[0012] Further, one end of the movable rod is provided with a torsional spring that always forces the movable rod to be in a state of limiting the locking part, the torsional spring has a certain elasticity to limit children from easily operating the child lock structure, and also gives the handle a certain damping to make the handle have a hand feeling when being operated.
[0013] As a preference, the middle part of the handle is movably connected with the other end of the movable rod through a positioning pin, and the positioning pin is limited by a clamping spring.
[0014] Further, the second base is transversely extended with a stop column for limiting the movement of the movable rod to reverse downwards. The stop column can limit the amplitude of the handle driving the movable rod to reverse downwards.
[0015] The bottom of the door body is rotatably arranged at the lower end of the port of the machine body.

[0023] The utility model will be further described in detail below in combination with the embodiment of the drawings.
[0024] As shown in Figure 1 and Figure 5 , the washing machine in the embodiment comprises a machine body 1 and a door body 2 arranged at the port of the machine body 1, the bottom of the door body 2 is rotatably arranged at the lower end of the port of the machine body 1. The top of the door body 2 extends a lock piece 5, the end of the lock piece 5 is provided with a locking part, the top of the machine body 1 is reversibly provided with a movable rod 4 and a handle 3, the movable rod 4 is provided with a limiting part for limiting the locking part from separating from the top of the machine body 1, the middle part of the handle 3 is movably connected with one end of the movable rod 4 and can drive the movable rod 4 to reverse, after the handle 3 drives the movable rod 4 to reverse upwards, the limiting part separates from the locking part, and then the lock piece 5 can separate from the top of the machine body 1.
[0025] In combination with Figure 2 As shown, the locking part is a locking arm 51 extending upward from the locking piece 5, and the limiting part is a cavity 41 formed in the middle of the movable rod 4. After the handle 3 drives the movable rod 4 to flip upward, the locking arm 51 is disengaged from the cavity 41 of the movable rod 4, and then the locking piece 5 can be disengaged from the top of the body 1. The locking arm 51 is two and arranged in intervals, and the cavity 41 is also two and arranged in intervals.
[0026] The top is provided with a first base 6 and a second base 7 arranged adjacent to the first base 6. One end of the movable rod 4 is rotatably arranged on the first base 6, and one end of the handle 3 is rotatably arranged on the second base 7 and movably connected with the other end of the movable rod 4 in the middle. The movable rod 4 is provided with a torsion spring that always forces the movable rod 4 to be in the limiting state of the locking part. The handle 3 is movably connected with the other end of the movable rod 4 in the middle through a positioning pin 8, and the positioning pin 8 is limited by a snap spring 81. The second base 7 is provided with a stop column 71 extending transversely to limit the movement of the movable rod 4.
[0027] Working principle: when there are children at home and the child lock needs to be opened, the locking arm on the locking piece on the door body can cooperate with the two cavities on the movable rod after the door body is closed, so as to limit the door body from being opened at will, and the child lock is opened, as shown in Figure 1 .
[0028] When the child lock needs to be closed (i.e. when the door body is opened), as shown in Figure 3 , the handle can be lifted upward at this time, so that the movable rod follows the handle and is lifted upward together; as shown in Figure 4 , when lifted to a certain height, the locking arm on the locking piece can be disengaged from the cavity of the movable rod, and then the door body can be opened. After the door body is opened, as shown in Figure 5 .
[0029] The child lock is simple and convenient to operate, does not need to be controlled by electricity, and has a pure mechanical structure and good stability. The child lock structure is arranged on the top of the body, and children cannot easily touch it, so as to ensure that it cannot be easily opened.
