Abstract
The utility model relates to a timing switch with a safety protection device of a household electrical appliance. The timing switch comprises a casing (1), a power plug (2), a power switch (3), a power indicating lamp (4), a power socket (5) and a timing switch body (6); and is characterized in that the casing (1) is provided with a leakage protector reset button (7) and a time adjustable time-delay relay (8). The power plug (2) is connected with the input end of a leakage protector (9) via the power switch (3), the output end of the leakage protector (9) is connected with the input end of the timing switch body (6), the output end of the timing switch body (6) is connected with the input end of the time adjustable time-delay relay (8), and the output end of the time adjustable time-delay relay (8) is connected with power socket (5). The timing switch is safe and reliable, and can effectively protect the household electrical appliance from damage.
Description
Technical field
The utility model belongs to Household appliance switch technical field, relates in particular to a kind of household electrical appliance regular switching device with safety guard.
Background technology
At present, household electrical appliance are more and more, and some electrical appliance is electric fan for example, and washing machine, on the household electrical appliance such as television set, has the timing switch carrying, and these timing switches are to be all directly installed on the control panel of household electrical appliance.Be used for controlling start and the shutoff of the machine.Also have a lot of household electrical appliance there is no timing switch, such as electric heater, insulating pot, ventilating fan, fish tank illumination and inflation etc., lean on people constantly open or turn-off.In addition, some electrical equipment when people not time also need to open, for example, in summer, before need to coming home from work, to open in advance air conditioner refrigerating, think in addition to allow in advance before leaving offices the burned hot water of insulating pot etc.For this reason, there are in the market various regular switching devices.But these regular switching device majorities are only timing switches, defencive function shortcoming.Because mostly the time with regular switching device is, in situation that people are absent from the scene, often can cause household electrical appliance to damage when regular switching device damages or be malfunctioning, more serious can fire hazard.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, and a kind of household electrical appliance regular switching device with safeguard protection is provided.The purpose of this utility model is to be achieved through the following technical solutions: a kind of household electrical appliance regular switching device with safeguard protection; include housing, attaching plug, mains switch, power supply indicator, supply socket and regular switching device; regular switching device is multi-functional, is provided with display screen, start, unused time adjustment membrane keyboard and start and close indicator light.It is characterized in that: housing is provided with earth leakage protective device reset button and time graded time-lag relay, time graded time-lag relay is provided with display screen and the time is adjusted membrane keyboard.Each parts are finished parts; its annexation is: attaching plug mains switch connects the input of earth leakage protective device; the output of earth leakage protective device and the input of regular switching device join; the input of the output of regular switching device and time graded time-lag relay joins, the output termination supply socket of time graded time-lag relay.Its operation principle is: switch on power, adjust start and the unused time of regular switching device, and adjust the turn-off time of time graded time-lag relay, general time-delay relay is adjusted at time delay number minute than the available machine time of regular switching device and turn-offs.When circuit is normal, after regular switching device shutdown, time graded time-lag relay dead electricity, stops electrical appliance powering.If regular switching device is malfunctioning or damage, can not shut down, now, time graded time-lag relay extends several minutes and turn-offs, and protection electrical appliance can not power up for a long time and damage; If electrical appliance, regular switching device or time graded time-lag relay electric leakage, the earth leakage protective device power-off of all can tripping, has protected whole power consumption equipment.
The utility model is safe and reliable, is the not impaired regular switching devices of a kind of effective protection household electrical appliance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is circuit connection structure schematic diagram of the present utility model.
In figure, 1, housing, 2, attaching plug, 3, mains switch, 4, power supply indicator, 5, supply socket, 6, regular switching device, 7, earth leakage protective device reset button, 8, time graded time-lag relay, 9, earth leakage protective device.
Embodiment
With reference to accompanying drawing; a kind of household electrical appliance regular switching device with safeguard protection; include housing 1, attaching plug 2, mains switch 3, power supply indicator 4, supply socket 5 and regular switching device 6; regular switching device 6 is multi-functional, is provided with display screen, start, unused time adjustment membrane keyboard and start and close indicator light.It is characterized in that: housing 1 is provided with earth leakage protective device reset button 7 and time graded time-lag relay 8, time graded time-lag relay 8 is provided with display screen and the time is adjusted membrane keyboard.Each parts are finished parts; its annexation is: attaching plug 2 connects the input of earth leakage protective device 9 through mains switch 3; the input of the output of earth leakage protective device 9 and regular switching device 6 joins; the input of the output of regular switching device 6 and time graded time-lag relay 8 joins, the output termination supply socket 5 of time graded time-lag relay 8.Its operation principle is: switch on power, adjust start and the unused time of regular switching device 6, and adjust the turn-off time of time graded time-lag relay 8, general time-delay relay is adjusted at time delay number minute than the available machine time of regular switching device and turn-offs.When circuit is normal, after regular switching device shutdown, time graded time-lag relay dead electricity, stops electrical appliance powering.If regular switching device is malfunctioning or damage, can not shut down, now, time graded time-lag relay extends several minutes and turn-offs, and protection electrical appliance can not power up for a long time and damage; If electrical appliance, regular switching device or time graded time-lag relay electric leakage, the earth leakage protective device power-off of all can tripping, has protected whole power consumption equipment.
Claims (1)
1. a household electrical appliance regular switching device with safeguard protection, include housing (1), attaching plug (2), mains switch (3), power supply indicator (4), supply socket (5) and regular switching device (6), it is characterized in that: housing (1) is provided with earth leakage protective device reset button (7) and time graded time-lag relay (8), its annexation is: attaching plug (2) connects the input of earth leakage protective device (9) through mains switch (3), the input of the output of earth leakage protective device (9) and regular switching device (6) joins, the input of the output of regular switching device (6) and time graded time-lag relay (8) joins, the output termination supply socket (5) of time graded time-lag relay (8).
