Embodiment 1

[0027] see figure 1 ,

[0028] The water-saving control method for the grooved toilet adopts the following water-saving control device for the grooved toilet. The water-saving control device for the gutter type toilet is suitable for long strip urinals. The water-saving control device for the trench type toilet includes a detector 2 for detecting human body signals, a controller 1 and a water discharge mechanism 3, and the controller 1 is respectively connected to the detector 2 and the water discharge mechanism 3 with signals. The controller 1 is also provided with a clock controller connected to the controller 1 for providing a time signal, so as to determine the change of the daily time. The detector 2 sends the detected human body signal to the controller 1, and the controller 1 analyzes and processes the information from the detector 2 and the clock controller and controls the water releasing mechanism 3 to release water. It can be transformed into a clock controller b...

Embodiment 2

[0044] see figure 1 with image 3, this groove type toilet water saving control device is suitable for long urinals. The water-saving control method of this trench type toilet is the same as that of Embodiment 1. The difference between this groove type toilet water-saving control device and Embodiment 1 is that: the water discharge mechanism 3 also includes a water storage tank 33 arranged on the water supply pipeline 4, and the water outlet of the water storage tank 33 is respectively connected to the automatic The water inlets of the flush valve 31 and the manual flush valve 32 are connected. For the long urinal, the easiest way is to use the traditional water storage tank, which has a strong flushing power and is easy to flush. The water intake control of the water storage tank 33 adopts the overflow self-closing mode, which is the same as the water tank control mode of the domestic toilet. When the water in the water storage tank 33 was full, the water inlet valve was ...

Abstract

The invention discloses a water-saving control device for a groove type washroom and a method thereof. The device comprises a detector, a controller and a water-discharging mechanism. The controller is respectively connected with the detector and the water-discharging mechanism through signals, and the controller is provided with a clock controller having a daytime mode and a night mode. The daytime mode and night mode are decided by the time of the clock controller and preset settings. In the control method, firstly, the detector sends a detected human body signal to the controller; then, the controller analyzes and processes the signals detected by the detector and decides when to fill water according to the mode; and at last, the controller sends a water discharging instruct to the water-discharging mechanism. By adopting the invention, the time and the frequency for flushing can bed determined scientifically and reasonably according to time and the number of people entering the washroom, thereby the water resource can be furthest saved under the condition of keeping a washroom clean.

Description

technical field [0001] The invention relates to the field of toilet water-saving control, in particular to a water-saving control device and method for a trench type toilet. Background technique [0002] my country is a country that is extremely short of water resources, especially in most parts of northern my country, a drop of water is as expensive as oil. Therefore, the study of water-saving control has always been a hot topic, and toilet water-saving is also one of many water-saving research topics. At present, there are many types of water-saving control methods and controllers for long-trough toilets used in the field, and the manufacturers are also different. However, the control rules all adopt extensive control methods, without in-depth and detailed research on the specific conditions of toilets, and specific measures are taken for water-saving control according to specific conditions, so as to further improve water-saving efficiency. For example, the water-saving...
