Abstract

The utility model relates to a domestic electric appliance starting time controller which comprises an alarm watch and a socket. The utility model is characterized in that the utility model also comprises a switching circuit which is connected with a time giving mechanism of the alarm watch, a relay which is connected with an output terminal of the switching circuit, and a direct current power supply which can do power supply for the switching circuit. A normally open contact of the relay is connected with the socket in series at the front end of the direct current power supply, so a return circuit can be formed. When the utility model is used, at stated time, the power supply of the electric appliance can be automatically switched on; thereby, users can be provided with convenient use, and much time can be saved. The utility model can be connected with an electric rice cooker, an electric radiator, a television, audio equipment and other domestic electric appliances; thus, the timing play is realized.

Description

Household electrical appliance controller start-up time

The utility model is a kind of household electrical appliance controller start-up time.

Now be subjected to everybody liking as household electrical appliance such as electric rice cooker, electric heaters, obtained general application, bring great convenience for user's life, but Artificial Control is all wanted in the startup of existing household electrical appliance, this point makes everybody feel blemish in an otherwise perfect thing again.

The purpose of this utility model provides a kind of novel household electrical appliance controller start-up time, and it can overcome existing shortcoming in the prior art, realizes the automatic startup of household electrical appliance, can bring bigger convenience to people.

The purpose of this utility model is achieved in that it comprises an alarm watch and a socket, it is characterized in that it also comprises and give the correct time switching circuit that mechanism links and be connected the relay of switching circuit output and be the switching circuit direct current power source supplying power of alarm watch, the normally opened contact of relay and socket are in the DC power supply front end formation loop of connecting.

The utility model is by the Current Control Relay that gives the correct time of alarm watch, and the power supply of the contact control socket by relay, arrives when the alarm watch time of giving the correct time, its switch connection that gives the correct time, make the switching circuit conducting, relay power, its contact is connected, socket is had, electrical appliance promptly can be worked, and the switch time-delay of the circuit that gives the correct time disconnected after 50 minutes, the relay outage, connect electricity and disconnect, cut off the power supply of electrical appliance simultaneously.

The utility model has the advantages that the power supply that to connect electrical appliance at preset time automatically, before for example getting up in the morning, the power supply of electric rice cooker and electric heater is connected automatically, when people's WA, and indoor warm appropriateness, meal cooked food perfume (or spice), so it not only can bring great convenience to people, save a lot of times simultaneously, it can also link with household electrical appliance such as television set, stereo sets, realize regularly playing, that gives people gives birth to or brings great enjoyment.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.

Fig. 1 is use principle figure of the present utility model.

Fig. 2 is an electrical schematic of the present utility model.

Fig. 3 is an outline drawing of the present utility model.

The A end connects the circuit output end that gives the correct time of alarm watch among the figure, wherein K is the control switch of circuit of giving the correct time, by Q1, the switching circuit that Q2 forms is connected in this output, J is a relay, be connected the output of switching circuit, by rectifier D, the DC power supply that filter C2 and pressurizer WD form is connected on the switching circuit, the normally opened contact J1 of relay connects with socket P and constitutes the loop, when the 220V alternating current enters C1, through bridge rectifier and filtering, after the voltage stabilizing, to relay J, this moment, switching circuit did not have conducting, so J1 cut-offs, socket is not charged, when the alarm watch circuit start that gives the correct time, K connects, make entire circuit form the loop, the switching circuit conducting, J is charged, the J1 conducting, make socket charged, at this moment the electrical appliance that attaching plug has been inserted on the socket is promptly started working, because the K time-delay disconnected in 50 minutes, so after 50 minutes, this controller cuts off the power supply of electrical appliance automatically.What adopt among the above-described embodiment is that quartzy repeat watch or numeral show the electronic timekeeping table.

The utility model can also adopt mechanical repeat watch, as adopts mechanical repeat watch, then can establish a K switch in quarter-bell knob place behind watchcase, and the A in the foregoing description is terminated on the switch, utilizes the rotation of quarter-bell knob to make switch closure.

As shown in Figure 3, adorn a socket and a plug on the watchcase with repeat watch, and control circuit is loaded in the watchcase, can make the utility model compact conformation, volume-diminished.

Claims

1, household electrical appliance controller start-up time, it comprises an alarm watch and a socket, it is characterized in that it also comprises and give the correct time switching circuit that mechanism links and be connected the relay of switching circuit output and be the switching circuit direct current power source supplying power of alarm watch, the normally opened contact of relay and socket are in the DC power supply front end formation loop of connecting.

2, according to the said controller of claim 1, it is characterized in that on the housing of alarm watch a socket and a plug being housed, control circuit is loaded in the watchcase.
