Description

An intelligent water-saving device for domestic water heaters

technical field

The invention relates to the field of energy saving of water heaters, in particular to an intelligent water saving device for household water heaters.

Background technique

With the development of social industry, various high-efficiency water heaters emerge in endlessly in terms of household water heaters, and the efficiency of water heaters is also getting higher and higher. Today's electric water heaters, solar water heaters, and air energy water heaters are becoming more and more common, but they are still There are certain problems, that is, when the water heater just started working, the outlet water temperature of the water outlet was not high, causing the cold water with insufficient temperature to be directly let off and causing a waste of water resources. The method can divert the cold water and return it to the cold water inlet for reuse, thereby avoiding the waste of water resources to a certain extent.

Contents of the invention

The purpose of the present invention is to solve the above technical problems and provide a device for automatically diverting cold water, which can not only meet people's demand for hot water, but also automatically filter cold water and divert cold water for people to reuse.

To achieve the above object, the present invention adopts the following technical solutions:

The intelligent water-saving device has a core module that detects changes in water temperature and then controls the movement of the stepping motor, and has a water outlet pipe that detects water temperature and is equipped with a temperature sensor. The water pipe of the rotating cold and hot water semicircular water baffle is used to realize the diversion of hot water and cold water. The diverted cold water is directly connected with the cold water inlet of the water heater, and the diverted hot water is directly used by the user.

The core module receives the temperature feedback brought by the water temperature sensor of the outlet pipe, and monitors the water temperature through the feedback of the temperature sensor. When the monitored water temperature reaches a certain value, the core module controls the rotation of the stepper motor to realize the closing of the semicircular water retaining plate, realizing The function of diverting cold or hot water.

The water outlet pipe is connected to the core module that controls the movement of the stepper motor by detecting changes in water temperature, and feeds back the outlet water temperature to the core module in real time, so as to achieve the purpose of the core module controlling the stepping motor to rotate the semicircular water barrier through the water temperature change. Realize the function of diverting cold water or hot water.

A semicircle water stop connected to the stepper motor is installed vertically above the water pipe, and the left and right rotation of the stepper motor is used to achieve the left and right closure of the semicircle water stop, and the stepping of the left and right closure of the cold and hot water semicircle water stop of the water pipe is controlled. The motor is connected to the core module through the motor drive. When the temperature of the water flow monitored by the core module changes, the core module controls the rotation of the stepper motor through the drive to close the semicircular water baffle to achieve the function of diverting cold water or hot water. A cold water pipe and a hot water pipe are also installed in the middle of the water pipe, and when the cold and hot water semicircle water retaining sheet is closed, the water flow can flow out from the cold water pipe or the hot water pipe.

The cold water pipe installed in the middle of the water pipe is directly connected with the cold water inlet of the water heater, so that the cold water directly flows into the cold water inlet of the water heater, so that the cold water that has not reached the temperature can flow back to achieve the function of saving water.

The present invention has with advantage:

1. The invention realizes the diversion of cold water and hot water through the monitoring of the change of water temperature by the core module, avoids the waste of water resources, has a certain water-saving function, and provides a method for the reuse of water resources.

2. The principle of the present invention is simple, and the water pipe structure is easy to design and easy to install.

3. The present invention realizes functions through the control of the core module, and has high working efficiency.

detailed description

Below, the substantive features and advantages of the present invention will be further described in conjunction with examples, but the present invention is not limited to the listed examples.

Please refer to Figures 1 to 4 , an intelligent water-saving device for household water heaters, including a water outlet pipe 1 equipped with a water temperature sensor, and a water temperature sensor probe 2 is installed inside the water outlet pipe 1 installed with the water temperature sensor , a water pipe 3 equipped with a cold and hot water semicircle water stop 7 is connected below the water outlet pipe 1 equipped with a water temperature sensor, and the cold and hot water semicircle water stop 7 is connected to the connecting rod 6, and the connecting rod 6 is connected to the stepping motor Connected for rotation, the water pipe 3 with the cold and hot water semicircular water retaining piece 7 is divided into two channels, which are respectively the cold water outlet pipe 4 and the hot water outlet pipe 5, and the cold water outlet pipe 4 is directly connected to the cold water inlet 8 of the water heater. connect.

When the water heater comes out, the water temperature sensor 2 starts to detect the water temperature and feeds back the water temperature to the core control module. When the water temperature monitored by the core control module is lower than the set temperature of 40 degrees, it will drive and control the rotation of the stepper motor to achieve the rotation of the connecting rod 6. The purpose is to rotate the cold and hot water semicircle water retaining piece 7 connected with the connecting rod 6 to the direction of the hot water outlet pipe 5, and form a closure at the entrance of the hot water outlet pipe 5, so that the water flow can only flow out through the cold water outlet pipe 4, And directly flow into the cold water inlet 8 of the water heater, realizing the function of saving water.

When the water heater comes out, the water temperature sensor 2 starts to detect the water temperature and feeds back the water temperature to the core control module. When the water temperature monitored by the core control module is 40 degrees higher than the set temperature, it will control the rotation of the stepping motor by driving to achieve the rotation speed of the connecting rod 6. The purpose is to rotate the cold and hot water semicircle water retaining plate 7 connected with the connecting rod 6 to the direction of the cold water outlet pipe 4, and form a closure at the entrance of the cold water outlet pipe 4, so that the water flow can only flow out through the hot water outlet pipe 5, and flow out The hot water for people to use, this is the hot water mode.
