Abstract

The utility model discloses a remote controller for domestic electrical equipment, comprising a body, a remote controlling key, a panel, etc. The utility model is characterized in that the body of the remote controller is provided with a lighting device connected with one or a plurality of keys; the key can be additionally arranged on the panel of the remote controller; the key can also directly utilize an original remote controlling key on the remote controller to control the on-off of the lighting device, which realizes the illumination for the panel of the remote controller or a display screen; the lighting device can be connected with a time delay circuit and the key; after the lighting device is controlled by the time delay circuit to be turned on for a period of time, the time delay circuit is automatically turned off. The remote controller is especially suitable for controlling an electric appliance at night, such as an air conditioner, etc.

Description

The household electrical appliance remote controller that can throw light on

The utility model relates to a kind of household electrical appliance remote controller, for example is used for the remote controller of air conditioner, television set etc.

Raising along with people's living standard, electrical equipment in the people family is more and more, and the use of remote controller brings great convenience to people, but some inconveniences have in use also been exposed, for example in the use of air-conditioning remote control, we are set in air-conditioning some fixing temperature but are usually frozen because air-conditioning is opened cold or overheated in the sleep process and wake up or hot waking up before evening is sleeping, have a drowsy look we to regulate the temperature of air-conditioning at this moment and can only the utmost point reluctantly turn on the light so that see temperature on the remote control screen clearly, Deng but find after temperature is mixed up sleepiness completely without, so like that lazy people just usually regulate the temperature of air-conditioning in the dark but such temperature of regulating often is not again very accurate, sleeping being frozen again waken up or hot waking up.Even if this moment, modern electrical equipment also made us feel inconvenient one side, similarly, other electrical equipment in use also has similar problem.

The purpose of this utility model is exactly to provide a kind of remote controller in order to overcome the above problems, and can use easily in the dark and need not turn on light, and avoids the night high light to people's influence.

The utility model realizes that the scheme of above-mentioned purpose is: a kind of household electrical appliance remote controller, comprise body 1, teleswitch 2 and panel etc., it is characterized in that: described remote controller body 1 is provided with lighting device 3, lighting device 3 links to each other with button J1, this button J1 sets up on telecontrol panel specially, or directly utilize teleswitch 2 on the remote controller, with the Kai Heguan of control lighting device 3, realize illumination to telecontrol panel.

Owing to adopted above scheme, one or more lighting devices (luminous element) in remote controller, have been added, when using a teleswitch so in the dark, can utilize this lighting device that the screen or the teleswitch of remote controller are thrown light on, avoid blindly operation and do not need to use indoor obvious too strong light.

Fig. 1 is the utility model embodiment remote controller schematic diagram.

Fig. 2 is a self-locking button schematic diagram.

Fig. 3 is non-self-locking button schematic diagram.

Fig. 4 is a software assist control schematic diagram.

Fig. 5 is a schematic diagram of using the EL backlight.

Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.

See Fig. 1, be depicted as household electrical appliance remote controller and comprise body 1, teleswitch 2 and panel etc., it is characterized in that: described remote controller body 1 is provided with lighting device 3, lighting device 3 links to each other with a button J1, this button J1 sets up on telecontrol panel specially, or directly utilize teleswitch 2 on the remote controller, with the Kai Heguan of control lighting device 3, realize illumination to telecontrol panel.

Described lighting device is that miniature bulb, luminous tube, EL backlight etc. are any, or several shared; Its installation site is as the criterion with the front that can illuminate remote controller, and purpose is in order to see display screen or the button on the remote controller clearly.Such as being contained in below the display screen teleswitch next door etc.The circuit of miniature bulb and luminous tube is very simple, and this does not describe in detail.EL backlight circuit also is easy to, and is an example as shown in Figure 5, and wherein lighting device 3 is EL backlight.

Described button can be the self-locking button, and the back button that promptly pushes button can not upspring automatically, unless press once, its connection can be as shown in Figure 2 again, and wherein Vcc/Ctrl represents power end or control signal end; Also can be non-self-locking button, unclamp the hand button after promptly pushing button and just can upspring that its connection example as shown in Figure 3.Two kinds of buttons all have ready-made product.

During specific implementation, two kinds of methods can be arranged, a kind of be increase by one independently button control described lighting device, being advisable with the front of remote controller in the installation site of the button of increase, just shows this situation as Fig. 1.Another kind is directly the teleswitch on the remote controller 2 to be linked to each other with lighting device 3, presses the unlatching that teleswitch 2 is the may command lighting device, has so just utilized the original button of remote controller.Closing then of lighting device 3 controlled by delay circuit or by software.

Described lighting device 3 can also link to each other with button J1 by a delay circuit, and described delay circuit is controlled described lighting device 3 and automatically shut down after connecting a period of time.This circuit can have multiple implementation, because delay circuit is a common circuit, its implementation is varied.One example has been shown among Fig. 3.In Fig. 3, described delay circuit comprises first resistance R 1, second resistance R 2, capacitor C 1, triode Q1 etc., an end ground connection after capacitor C 1 and the button J1 parallel connection wherein, the other end meets positive source Vcc by first resistance R 1, connects the base stage of triode Q1 by second resistance R 2; The collector and emitter of triode Q1 has an end ground connection, and the other end is connected to lighting device 3.

The use of delay circuit can guarantee can save electric power using rear lighting unit 3 to cut off automatically through certain hour.Closing of lighting device 3 can also realize manually, for example clicks button J1 and just opens, and clicks J1 again and just closes (being used for non-self-locking button); Or button just pressed open, button has just been pressed closed (otherwise or, be used for the self-locking button).

In addition, can also use the software assist control, accompanying drawing 4 shows an example.The signal of pressing system lighting device 3 break-makes is from control chip.And sending of chip controls signal ctrl is by providing behind the state that detects each button on the telecontrol panel.This does not describe in detail its concrete software.
