Description

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 sprayed out instantly, 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 the 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 the power is 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 the power is 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 the 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.

[0023] The utility model will be described in further detail below in combination with the drawings of the embodiments.

[0024] As Figure 1 and Figure 7 shown, the dishwasher comprises a machine body 1 and a door body 2 arranged at the port of the machine body 1, the door body 2 is arranged on the machine body 1 in an openable and closable manner, specifically, the bottom of the door body 2 is rotatably arranged at the lower end of the port of the machine body 1.

[0025] The top of the door body 2 extends a lock piece 5, the end of the lock piece 5 has a lock hole 51, the top of the machine body 1 is reversibly provided with a lock catch 4, one end of the lock catch 4 has a hook portion 41 capable of locking the lock hole 51.

[0026] As Figure 2 , Figure 3 and Figure 4 shown, the top of the machine body 1 is provided with a base 3, the lock catch 4 is reversibly arranged on the base 3 through a shaft pin 7. The base 3 comprises an installation portion 32 in the middle and connecting portions 31 at both ends of the installation portion 32, the installation portion 32 is concave to form a containing area, the lock catch 4 is arranged in the containing area and is reversible, the connecting portions 31 are arranged at the top of the machine body 1 through a connecting member 6, the connecting member 6 in the embodiment can adopt a screw. The middle portion 43 of the lock catch 4 is arranged on the base 3 through the shaft pin 7, one end away from the hook portion 41 has a force applying portion 42, in the state of being pushed upward by the force applying portion 42, the hook portion 41 can be turned downward.

[0027] The door body 2 has a ring-shaped metal sheet 21 around the edge on the inner side, and the machine body 1 has a ring of sealing strips 11 around the port, which are sealingly adapted to the metal sheet 21 and have elasticity; the metal sheet 21 of the door body 2 presses inward to compress the sealing strips 11, and after pressing the lock piece 5 downward, the lock catch 4 can be disengaged from the lock hole 51.

[0028] Working principle: when the child safety lock needs to be opened (when there are children in the house), the force applying part of the lock catch can be actuated after the door body is closed, the lock catch is flipped, and the lock hole on the lock piece cooperates with the hook part of the lock catch, so that the child safety lock is not easy to be opened, as shown in Figure 1 .

[0029] When the child safety lock needs to be closed, the door body is pushed inward, and the lock piece moves forward, and the lock piece is pressed downward again (the lock piece is thin and can be freely pressed downward), so that the lock piece is disengaged from the hook part, and the force applying part is actuated again to flip the lock catch, so that the child safety lock is in a closed state after the lock piece is disengaged from the hook, as shown in Figure 6 . The child safety lock is simple to operate and does not need to be electrically controlled, and is a pure mechanical structure with good stability. The child safety lock structure is arranged at the top of the machine body and is not easy to be touched by children, so that it cannot be easily opened.
