Problems solved by technology

[0003] But the child lock of this prior art still has the following problems: the first, the frequency of use of the sink dishwasher is high, therefore, all will set and open the child lock before using each time, bring inconvenience to the user, the second, even if The child lock button is set, and there are cases where children touch the switch button of the child lock and the child lock becomes invalid, so the security is insufficient

Embodiment 1

[0023] The control instructions include locking instructions and unlocking instructions. Wherein, when the electronic control lock 3 is in the unlocked state, if any two or more key switches 4 trigger the switch signal at the same time, the processor 5 receives the two switch signals to generate a locking instruction, and the locking instruction controls the electronic control lock 3 Switch to the locked state. Among them, when the electronic control lock 3 is in the locked state, the processor calibrates the two key switches 4 as specific key switches, and there is a gap greater than 80mm between the two specific key switches. If the switching signals of the two specific key switches are triggered at the same time Then, the processor receives the two switch signals to generate an unlocking instruction, and the unlocking instruction controls the electronic lock 3 to switch to the unlocked state.

[0024] Further, when the electric control lock 3 is in the locked state, the proce...

Embodiment 2

[0027] A first sensor 6 is provided between the washing tank 1 and the cover plate 2, and the first sensor 6 is electrically connected to the processor 5 for detecting that the cover plate 2 is opened or closed on the washing tank 1. The first sensor 6 can be installed on the sink 1 or the cover 2 or between the two. If the cover 2 is in the open state, the electric control lock 3 will fail. If the cover 2 is switched from the open state to the closed state State, the electric control lock 3 is reset to the unlocked state. The above-mentioned first sensor 6 detects that when the cover 2 is in the open state, the priority of the detection signal sent out is higher than the priority of the control command, that is, the control command is invalid when the cover 2 is in the open state, and the electric control lock 3 The power failure fails, thereby avoiding that the cover plate 2 is quickly closed due to the suction force of the electric control lock 3 in the open state, which may...

Embodiment 3

[0029] The basic mechanism of this embodiment is the same as the above-mentioned control system. The difference is that it also includes a first timer 7, which is electrically connected to the processor 5 and the key switch 4. In the unlock command, if two When the switch signal of the specific key switch is triggered at the same time, the processor 5 controls the first timer 7 to start timing. If the switch signal of any specific key switch is lost, the first timer 7 is cleared. When the accumulated time of the first timer 7 reaches the set value At a fixed time value, the electric control lock 3 switches to the unlocked state. The above-mentioned clearing of the first timer 7 means that the first timer 7 is reset to the initial state.

[0030] The above setting time can be set before leaving the factory according to different occasions, or can be set by maintenance personnel or users. The set time can be any time value from 1 second to 5 seconds. The first timer 7 can prevent...

Abstract

The invention discloses a child lock control system for a sink dishwasher. The system comprises a a sink, a movable cover plate is arranged on the sink, an electric lock is arranged between the coverplate and the sink, a processor and multiple button switches are integrated on the cover plate, controlling commands are formed by interlinking of switching signals between at least two button switches, and the controlling commands comprise a locking command and an locking command. When the electric lock is in an unlocking state, if the switching signals are triggered simultaneously by any two ormore than two button switches, the electric lock is controlled by the processor to switch to a locking state; two button switches are marked as specific button switches when the electric lock is in the locking state, a spacing of 80mm is reserved between the specific button switches, and the electric lock is controlled by the processor to switch to the unlocking state if the switch signals of thespecific button switches are triggered simultaneously. According to the child lock, the lock is not easily unlocked by children and is simple and convenient to operate.

Description

Technical field [0001] The invention relates to the technical field of sink dishwashers, in particular to a control system of a child lock for sink dishwashers. Background technique [0002] The sink dishwasher is a new type of kitchen appliance produced with the development of household appliances, and because the sink dishwasher is often accompanied by hot water washing, hot air drying, infrared sterilization, etc., the sink is used to wash dishes How to avoid children accidentally touching and causing safety problems during the use of the machine is particularly important. Therefore, the existing sink dishwashers generally learn from the child lock of traditional electrical appliances, that is, opening the child lock makes the door cover locked during the operation of the electrical appliance, and resetting when the electrical appliance is finished running allows the door cover to be opened normally. [0003] However, this prior art child lock still has the following problems: ...
