Abstract

The utility model relates to a time delay timer controlled by a quartz analog clock, which is formed by connecting a casing, a quartz analog clock and a button indicating lamp which are installed on a front panel, a controlling circuit board installed in the casing and a power input plug and an output socket which are installed on a rear panel, wherein, the time setting knob of the quartz analog clock is used for setting the starting time, the power-on time is set by using a potentiometer and through a time relay, so that an electrical device connected on the output socket of the timer is automatically energized according to the scheduled time, and then automatically deenergized through the set time, and the electrical device can be controlled to automatically work and stop according to the scheduled time, such as an electric cooker, a ventilating fan and an advertising lightbox, etc. The time delay timer has the advantages of visual display and convenient operation.

Description

Pointer quartz clock controlled back off timer

Affiliated technical field

The utility model relates to a kind of household electrical appliance, is specially a kind of clock timer.

Background technology

At present, existing clock timer adopts liquid crystal digital to show mostly, is provided with by little button adjustment, and the setting only that has regularly can not be set time-delay, and in a word, existing clock timer shows that adjustment directly perceived inadequately makes things convenient for function complete inadequately inadequately.

The content of invention

Show directly perceived inadequately, the incomplete deficiency of the inconvenient function of adjustment in order to overcome existing clock timer, a kind of clock timer that the utility model provides, this clock timer adopts the pointer quartz alarm clock, show more directly perceived, set with knob, more convenient operation also has the delay adjustments function, and function is more complete.

The technical scheme that its technical matters that solves the utility model adopts is: by shell, be installed in pointer quartz alarm clock on the front panel and button pilot lamp, control circuit board in the enclosure be installed and power input plug and the accessory power outlet that is installed on the rear panel connects to form, set the startup working time with the pointer quartz alarm clock, set the length of working time by the time relay with potentiometer, thereby reach energising automatically on schedule, through the purpose of cutting off the power supply automatically after the time of setting.

The beneficial effects of the utility model are, make household electrical appliance energising automatically on schedule, through outage automatically after the time of setting, and intuitive display, easy to operate, multiple functional.

Embodiment

This timer power supply plug is inserted 220 volts of supply sockets, and the power lights 3 on the panel is bright, the electrical appliance attaching plug is inserted on the accessory power outlet 5 of this timer.

When functional select switch 13 pushes the A gear, this timer is operated in the clock pattern, mix up start-up time with clock time set knob 17, mix up the length of conduction time again with the delay adjustments potentiometer 15 on the panel, click and start button 8, relay K A2 adhesive also keeps, portable lamp 9 is bright, transformer 10 and 12 volts of DC voltage of current rectifying and wave filtering circuit work output, this moment, quartz alarm clock 14 contacts were in off-state because not arrive sets start-up time, relay K A3 and time KT do not work, not adhesive of relay K A1, accessory power outlet 5 no powers, output lamp 6 does not work.Quartz alarm clock 14 closings of contact when start-up time is set in arrival, the relay K A3 adhesive of switching on, make relay K A1 adhesive, accessory power outlet 5 energisings, output lamp 6 is bright, and the electrical equipment that is inserted on the accessory power outlet 5 is started working, simultaneously, time relay KT starts working, and when elapsed time reached the time of delay adjustments, the contact of time relay KT disconnected, relay K A2 dead electricity, relay K A1 is disconnected, accessory power outlet 5 outages, output lamp 6 extinguishes, the electrical equipment that is inserted on the accessory power outlet 5 quits work, transformer 10 and current rectifying and wave filtering circuit quit work, relay K A3 and delay circuit KT power-off restoration, and work is finished.

When functional select switch 13 pushes the B gear, this timer is operated in delay mode, mix up the length of conduction time with the delay adjustments potentiometer 15 on the panel, click and start button 8, relay K A2 adhesive also keeps, portable lamp 9 is bright, 12 volts of DC voltage of transformer 10 and current rectifying and wave filtering circuit work output, the relay K A3 adhesive of switching on, make relay K A1 adhesive, accessory power outlet 5 energisings, output lamp 6 is bright, and the electrical equipment that is inserted on the accessory power outlet 5 is started working, simultaneously, time relay KT starts working, and when elapsed time reached the time of delay adjustments, the contact of time relay KT disconnected, relay K A2 dead electricity, relay K A1 is disconnected, accessory power outlet 5 outages, output lamp 6 extinguishes, the electrical equipment that is inserted on the accessory power outlet 5 quits work, transformer 10 and current rectifying and wave filtering circuit quit work, relay K A3 and delay circuit KT power-off restoration, and work is finished.

Stop button 7 on the panel is used for quitting work at any time, when this timer is being worked, clicks stop button 7, and relay K A2 outage quits work this timer.

Test button 4 on the panel is used for testing this timer and the connection state that is inserted in the electrical equipment on the accessory power outlet 5, press the 4 relay K A1 adhesives of test button, accessory power outlet 5 energisings, this timer output lamp 6 is bright, if it is bright that be inserted in the power light of the electrical equipment on the accessory power outlet 5 this moment, illustrate to connect normally that release button resets.
