Abstract

A multifunctional household appliance remote controller with an alarm device comprises a signal transmitter and a signal receiver. The signal transmitter is in transmission connection with the signal receiver through wireless signals. The multifunctional household appliance is characterized in that the signal transmitter is arranged on the inner side of the lower end of a display of a television, a button is arranged at the front end of an outer casing of the television, the button is connected with the transmitter, and the receiving is arranged inside the front end of the remote controller. The transmitter consists of an oscillator and a high-frequency transmitting circuit, the oscillator is formed by a door circuit, and the receiver consists of a super regenerative detecting circuit, an amplifying circuit, a frequency selection circuit, a trigger circuit and a sound generation or vibration circuit. The receiver which is additionally arranged inside an original television wireless remote controller does not affect various remote control functions of original remote controllers of manufactures to televisions.

Description

The multi-functional domestic electrical equipment remote controller that has warning device

Technical field

The utility model relates to a kind of multi-functional domestic electrical equipment remote controller that has warning device, belongs to household electrical appliance accessory field.

Background technology

In actual life, usually have when needs use a teleswitch remote-controlled television set, find that but telepilot can not find, do not known to be put in that corner of family, often need to waste the more time just can find the placement location of telepilot.Employed Digiplex (remote control panel) on the household electrical appliance such as existing televisor, DVD player, function singleness can only can not provide other function by control (as channel selection, open and close, the sound adjusting etc.) of telepilot to household electrical appliance.At present, multi-functional domestic electrical equipment remote controller does not also appear on the market.

The utility model content

The purpose of this utility model is to provide a kind of multi-functional domestic electrical equipment remote controller that has warning device at the problems referred to above, this telepilot has not only kept the function of original telepilot, when telepilot can not find, by pressing the button on the televisor, telepilot can send alarm sound automatically, can allow the very fast telepilot of looking for of owner, in addition, when sharp pounding (as earthquake) or televisor taking place be moved the position, telepilot also can send alarm sound automatically, the prompting owner.

In order to achieve the above object, the utility model is realized by following technological means.

The multi-functional domestic electrical equipment remote controller that has warning device, it comprises signal projector and signal receiver two parts composition, transmit by wireless signal between signal projector and the signal receiver and be connected, it is characterized in that: the inboard in the television display lower end is provided with signal projector, shell front end at televisor is provided with a button, and button links to each other with transmitter; Be provided with a receiver in the front end inside of telepilot.

Described transmitter is to be made of oscillator and high frequency transmission circuit that gate circuit constitutes, and receiver is to be made of superregenerative detection circuit, amplifying circuit, frequency selection circuit, trigger circuit and sound equipment generation or vibrating circuit.

Described receiver is installed at the inside of original tv wireless telepilot, does not influence the various distant control functions of the original telepilot of producer to televisor.

In the use, receiver power supply is in normally open, when vibration after transmitter is subjected to button pressed downwards or the vibrations of other reason, and the K switch in the circuit ₃Connect, circuit is started working, and the carrier wave after the modulation is passed through printed antenna W ₂To aerial emission, the crystal oscillator JT in the utility model transmitter ₂With the crystal oscillator JT in the receiver ₁Frequency be corresponding.Receiving antenna W in receiver ₁After receiving the electromagnetic wave that transmitter sends, through triode VT ₁The detection demodulation is then through resistance R ₂, capacitor C ₇Be coupled to by " not gate " F ₁, F ₂, F ₃In the amplification and rectification circuit that constitutes, if its signal frequency and crystal oscillator JT ₁Resonance, then its impedance is very low, thereby enters triode VT smoothly ₂, other interference noises then can't pass through because impedance is very high.Advance the people to triode VT ₂Signal through amplifying by inverter F ₄, F ₅Trigger acoustics circuit IC after the shaping ₂Or Vib., thereby send chimes of doom or produce vibration, can point out owner like this.

The utility model mainly has following beneficial effect:

This telepilot has not only kept the function of original telepilot, when telepilot can not find, by pressing the button on the televisor, telepilot can send warning automatically, can allow the very fast telepilot of looking for of owner, in addition, in when, sharp pounding (as earthquake) or televisor taking place being moved the position when, telepilot also can send warning automatically, the prompting owner.

The utility model is described in further detail below in conjunction with embodiment and Figure of description:

Embodiment

As shown in Figure 1 and Figure 2, have the multi-functional domestic electrical equipment remote controller of warning device, it comprises that signal projector and signal receiver two parts form, and transmits by wireless signal between signal projector and the signal receiver to be connected.

As shown in Figure 1, be provided with signal projector in the inboard of television display lower end, be provided with a button 2 at the shell front end of televisor, button 2 links to each other with transmitter.

As shown in Figure 2, be provided with a receiver 4 in the front end inside of telepilot 3.

As shown in Figure 4, described transmitter is to be made of oscillator and high frequency transmission circuit that gate circuit constitutes.

As shown in Figure 3, receiver is to be made of superregenerative detection circuit, amplifying circuit, frequency selection circuit, trigger circuit and sound equipment generation or vibrating circuit.

As shown in Figure 2, described receiver is installed at the inside of original tv wireless telepilot 3, does not influence the various distant control functions of the original telepilot of producer to televisor.

As shown in Figure 3, Figure 4, in the use, receiver power supply is in normally open, when vibration after transmitter is subjected to button pressed downwards or the vibrations of other reason, and the K switch in the circuit ₃Connect, circuit is started working, and the carrier wave after the modulation is passed through printed antenna W ₂To aerial emission, the crystal oscillator JT in the utility model transmitter ₂With the crystal oscillator JT in the receiver ₁Frequency be corresponding.Receiving antenna W in receiver ₁After receiving the electromagnetic wave that transmitter sends, through triode VT ₁The detection demodulation is then through resistance R ₂, capacitor C ₇Be coupled to by " not gate " F ₁, F ₂, F ₃In the amplification and rectification circuit that constitutes, if its signal frequency and crystal oscillator JT ₁Resonance, then its impedance is very low, thereby enters triode VT smoothly ₂, other interference noises then can't pass through because impedance is very high.Advance the people to triode VT ₂Signal through amplifying by inverter F ₄, F ₅Trigger acoustics circuit IC after the shaping ₂Or Vib., thereby send chimes of doom or produce vibration, can point out owner like this.
