Abstract

The utility model relates to a device using heat release electricity infrared sensing remote control and a microelectronic technology to be used for remotely controlling the automatic water supply of a closet. The utility model is mainly characterized in that electromagnetic valves are connected in series among a water outlet pipe, a water tank and a water inlet. The electromagnetic valves are controlled by an electronic control box. A heat release electricity infrared sensing probe and a control circuit of a single chip computer are arranged in the electronic control box. The water tank has no water at ordinary times. When a closet is used, an induction signal of a human body is received, defecation and urination are differentiated by the single chip computer according to presetting procedures. Water supply is controlled. The structure of the closet does not need to be changed by the device using heat release electricity infrared sensing remote control and a microelectronic technology to be used for remotely controlling the automatic water supply of a closet. The device which uses heat release electricity infrared sensing remote control and a microelectronic technology to be used for remotely controlling the automatic water supply of a closet has simple structure and convenient installation. The water saving of the device which uses heat release electricity infrared sensing remote control and a microelectronic technology to be used for remotely controlling the automatic water supply achieves more than 45%, the opening and the closing of a ventilator can be simultaneously and automatically controlled, and the device using heat release electricity infrared sensing remote control and microelectronic technology to be used for remotely controlling the automatic water supply of a closet has marked energy saving effect.

Description

Can distinguish the saving toilet control gear that stool and urine is supplied water

The utility model relates to the control gear that adopts rpyroelectric infrared sensing remote control and microelectronic technology, is applicable to the automatic control to the water power consumption, is particularly useful for the control to toilet seat water and ventilator energising.

The toilet seat water tank of general family, toilet, hotel is a water on the trunkful, and opening and closing of ventilator, lighting burner also all is manual operation, not only inconvenience but also waste energy.

The purpose of this utility model is exactly to solve the problem that above-mentioned prior art exists, a kind of saving toilet control gear that can just need to control automatically the water yield on the toilet seat water tank under the prerequisite that does not change former water closet structure by size is provided, and this control gear also can open and close automatically controlling ventilator simultaneously with the lavatory.

The purpose of this utility model can realize in the following manner.

Between the water inlet port 2 of running water outlet port one and toilet seat water tank, be serially connected with solenoid valve 3, the automatically controlled termination Electronic Control Box 4 of solenoid valve, the structure of this Electronic Control Box is that the signal that is provided with the rpyroelectric infrared sensing probe receives and amplification circuit I, the governor circuit II that has single-chip microcomputer, switch executive circuit III connect step by step, switch executive circuit III is controlled electric appliance circuit I V in succession again, and governor circuit II also connects power circuit V.Single-chip microcomputer is distinguished the break-make of stool and urine and control switch executive circuit according to pre-set programs, and then just needs to open respectively solenoid valve by size and intake to 50% or 100% of water tank.

Electronic Control Box is installed in from the top of water closet 40-60cm or its left and right side, also can be installed on the ceiling board of water closet top.When human body is used the lavatory, be contained in the Electronic Control Box the rpyroelectric infrared sensing probe just acknowledge(ment) signal after amplifying, deliver to the single-chip microcomputer governor circuit, according to the difference of stool and urine with the lavatory time, detect the also switching time of control electromagnetic valve in real time, just needing by size to realize automatic loading water (water of urinating generally speaking is the 40%-60% of stool).

Major advantage of the present utility model is that structure that (1) does not change former water closet just can detect and control realization in real time and just needs automatic loading water by size; (2) this apparatus structure is simple, and is easy for installation, and water saving can reach more than 45%; (3) this device also can realize controlling automatically electrical equipment such as ventilator, lighting burner simultaneously, and water saving is economize on electricity again, remarkable in economical benefits.

The utility model is described in further detail below in conjunction with drawings and Examples.
