The intelligent power-saving water dispenser realizes thorough cut-off of a heating power supply of the water dispenser when no one is around by the aid of control of the intelligent controller, prevents repeated heating to affect drinking water quality, and simultaneously achieves the purposes of intelligent heating and power saving.

Description

The intelligent energy-saving water dispenser

Technical field

The utility model relates to water dispenser, relates in particular to a kind of intelligent energy-saving water dispenser.

Background technology

At present, after the normal domestic use water dispenser opening power, no matter have or not personnel in the room, no matter all are in heating, keeping warm mode at daytime or night always, the pure water in the heating tank is heated for a long time repeatedly, not only is unfavorable for drinking-water health but also suitable expense.

At present, occur a kind of infrared human body induction module of relay output type on the market, it adopts pyroelectric infrared sensor as detection means.Can detect the infrared ray of human or animal emission and export the sensor of the signal of telecommunication.Movable in the induction range of this module, the relay coil of module gets electric, its normally open contact closure.This module operating voltage direct current 12V, 140 ° of induction angles, induction radius 6-8 rice.

The utility model content

Can not cut off the power supply automatically and the shortcoming that heats and waste electric energy repeatedly that causes at existing water dispenser, the utility model provide a kind of can be according to having or not personnel activity's situation to control the intelligent energy-saving water dispenser that water dispenser switches on and off automatically in the field of employment.

The technical solution adopted in the utility model is: it comprises existing water dispenser, it is characterized in that, the intelligent controller of being made up of the Switching Power Supply of relay output type infrared human body induction module, single stabilization delay circuit and alternating current 220V change direct current 12V voltage is installed in water dispenser; Described single stabilization delay circuit is made up of 555 integrated packages, relay, delay capacitor and resistance; The annexation of above-mentioned components and parts is:

The ac power input end of Switching Power Supply also is connected in drinking-water AC power end of incoming cables, the steady delay circuit of direct current 12V voltage output end order of Switching Power Supply and the power voltage terminal of infrared human body induction module; The inductive probe of infrared human body induction module is installed in the one side of water dispenser housing towards people's activity space, the delay capacitor two ends of the steady delay circuit of output order of infrared human body induction module, the output relay normally opened contact of single stabilization delay circuit are connected in the water dispenser heating courage current supply circuit.

The utility model operation principle is: lay the place when movable as personnel at water dispenser, relay output type infrared human body induction module is triggered, the normally open contact closure of infrared human body induction module relay output, the both end voltage of delay capacitor is zero, the normally opened contact closure of the relay of single stabilization delay circuit, connect water dispenser heating courage current supply circuit, water dispenser begins operate as normal.The voltage swing at delay capacitor two ends has determined the output of the relay of single stabilization delay circuit, and the normally open contact that reaches 1/3Vcc its output relay when (Vcc refers to the working power voltage of delay circuit) when the delay capacitor charging voltage disconnects, otherwise contact closure.If in water dispenser peace place, room work activities, the infrared human body induction module will constantly be triggered personnel always, the heating courage will be always.If personnel are of short duration in water dispenser, module has only temporarily been triggered, the normally open contact of infrared human body induction module will be delayed time and be disconnected after several seconds, this moment, delay capacitor began charging, when both end voltage reaches 1/3Vcc, the normally open contact of delay circuit relay disconnects, and has cut off water dispenser heating courage current supply circuit.

Good effect of the present utility model is: thoroughly cut off the water dispenser heating power supply in the time of can accomplishing nobody, prevent to add repeatedly the heat affecting drinking water quality, reach the purpose of intelligent heating and economize on electricity simultaneously.

Description of drawings

Fig. 1 is circuit theory diagrams of the present utility model.

Among the figure: A-Switching Power Supply, B-infrared human body induction module, C-single stabilization delay circuit, D-inductive probe, F-intelligent controller, C ^*-delay capacitor.

The specific embodiment

As shown in Figure 1, at first make intelligent controller F, intelligent controller F is made up of infrared human body induction module B, Switching Power Supply A and the 555 single stabilization delay circuit C of relay output type, and Switching Power Supply A is that 220V exchanges change 12V direct current, exports the power supply of maximum current into 1A.Then intelligent controller F is installed in the water dispenser housing, during installation, exchanges the outlet side that one on lines of input are connected on the water dispenser total power switch with two of Switching Power Supply A, another root exchanges on the inlet wire of another root AC power that input line is connected on water dispenser.The direct current 12V output of Switching Power Supply A is received the supply voltage input of infrared human body induction module B and 555 single stabilization delay circuit C.Two output lines of the relay normally open contact of infrared human body induction module B are attempted by delay capacitor C ^*Two ends, the intelligent controller F that makes is installed in the water dispenser housing, the inductive probe D of infrared human body induction module B is installed on the water dispenser housing facing to people's activity space, and the normally open contact of the output relay of single stabilization delay circuit C is serially connected in the water dispenser heating courage current supply circuit.The circuit of intelligent controller F is shown in Fig. 1 frame of broken lines, and those skilled in the art can implement according to this figure, are not described in detail in this.
