Abstract
The utility model relates to an acoustic-optic display for displaying the washing terminate condition of a drum-type washing machine. The utility model is composed of a power switch, a power indicator light, a door lock indicator light, a buzzer, a door lock switch, a door lock indicator light, etc. One path of the power switch and door lock switch are connected in series, and are connected to a fire line. The other path and an on-off contact of a program controller are connected in series, and are connected to a zero line. The door lock indicator light and the buzzer are connected in parallel, and are connected with a contact of the door lock and the power switch. The utility model has the advantages of simple structure, and stable working condition. The error action of the washing machine can be effectively prevented.
Description
The utility model relates to a kind of acousto-optic display device that shows roller washing machine washing done state.
Roller washing machine generally uses the mechanical type program controller at present, and along with the operation of program, the program controller knob single-frame turns to " end " position.Because " end " position of control panel printing is a coarse localization, whether the user also must generally by listening washing machine drum whether whir is arranged, finish to judge laundry in conjunction with the motion conditions of washing machine.The user can't obtain a clear and definite signal prompt; learn the motion state of washing machine; and after each laundry finishes; after must waiting the PTC heater element of door lock inside to cool off fully; the taking-up clothing that just can open the door, and this section length cool time changes with the difference of environment temperature, because of the user can not accurately take the time; regular meeting opens the door before the door lock release by force, brings certain damage to washing machine.
It is stable that the purpose of this utility model provides a kind of operating mode, simple in structure, shows accurately roller washing machine running status display unit easy to use.
The utility model is by power switch S1, power supply indicator H1, door lock indicator lamp H2, program controller make break contact K, buzzer B, door interlock switch S2 and door lock resistance F form, a road of power switch S1 connects with door interlock switch S2 and to insert live wire, another Lu Yucheng device make break contact K series connection of power switch S1 inserts other line, power supply indicator H1 is connected in parallel on power switch S1 two-way rear portion, door lock indicator lamp H2 is in parallel with buzzer B, and the circuit rear portion in addition of connection door lock contact 4 and power switch S1, door lock resistance F one end connects rear portion, power switch S1 live wire road, and the other end connects program controller make break contact K rear portion.
The utility model is simple in structure, and after washing machine finished program for washing, door lock indicator lamp and buzzer were worked simultaneously, and sound, the dual demonstration of light are used very conveniently, can avoid maloperation, prevents to open gate too early and damages washing machine.
Accompanying drawing is the utility model example structure schematic diagram.
Referring to accompanying drawing, IN shown in the utility model, 2C, 3L, 4 are four contacts of commercially available four pin safety door latchs, and contact 2C directly is connected with existing laundry drum self-contained circuit 1 with program controller make break contact K.
When the user is selected wash and program after, for circuit 1 in the laundry, be equivalent to program controller make break contact K and be in on-state.When pressing power switch S1, power supply indicator H1 (can be redness) gets electroluminescence, and circuit is connected.This moment, the door lock resistance F two ends 3L and the 1N of safety door latch got, make door lock begin action, door lock contact 3L disconnects from auxiliary contact 4, connect door lock main contacts 2C, the washing machine circuit gets electric work, simultaneously door lock indicator lamp H2 (can be green) by bright to going out, and owing to the door lock resistance F of safety door latch always electricly keep extinguishing state.After laundry finished, program controller contact K disconnected, and door lock resistance is cooled to the release shape gradually.After the release, door lock contact 3L and main contacts 2C disconnect, and connect with auxiliary contact 4.The self-contained circuit 1 of doing washing this moment removes power switch, power supply indicator, door lock indicator lamp, the outer all outages of buzzer.Door lock indicator lamp H2 brightens by going out, and the buzzer sounding is reminded user's ends of doing washing, a release.This moment, but user's power cutoff was opened door of washing machine, took out clothing.
Claims (1)
1, a kind of by power switch S1, power supply indicator H1, door lock indicator lamp H2, program controller make break contact K, buzzer B, the roller washing machine running status display unit that door interlock switch S2 and door lock resistance F form, it is characterized by power switch S1-road connects with door interlock switch S2 and inserts live wire, connect with program controller make break contact K and insert other line in another road of power switch S2, power supply indicator H1 is connected in parallel on rear portion, power switch S1 two ends, door lock indicator lamp H2 is in parallel with buzzer B, and connection door lock contact 4 and another circuit rear portion of power switch S1, door lock resistance F one end connects rear portion, power switch S1 live wire road, and the other end connects program controller make break contact K rear portion.
