Description

smart water heater

technical field

The utility model relates to an intelligent water heater.

Background technique

In existing water heaters, after the hot water is slightly better, it needs to put cold water for a period of time before hot water comes out, which not only brings inconvenience to users, but also causes waste of water resources. Therefore, be necessary to design a kind of novel water heater.

Utility model content

The technical problem to be solved by the utility model is to provide an intelligent water heater, which can bring great convenience to users and save water resources.

The technical solution of the utility model is as follows:

An intelligent water heater, characterized in that a heater (3) and a first temperature sensor (6) are provided in the water tank (7), and a controller (4) and a display screen (5) are provided on the outer wall of the water tank (7) Both ends of the circulating water pipe (1) are connected with the water tank (7) to form a water circulation path, and a circulating pump (12) is connected in series on the circulating water pipe (1); a flow sensor (2) is provided at the entrance of the circulating water pipe (1) ; The water tap (11) communicates with the circulating water pipe (1) through the branch water pipe (10), the branch water pipe (10) is provided with an electric control water valve (9), and the entrance of the electric control water valve (9) is provided with a second temperature sensor (8);

The first temperature sensor (6), the second temperature sensor (8) and the flow sensor (2) are all connected with the controller (4);

The heater (3), circulation pump (12) and electric control water valve (9) are all controlled by the controller (4).

The controller (4) is a single-chip microcomputer or DSP.

Beneficial effect:

The intelligent water heater of the utility model allows cold water to flow back into the water tank before the water temperature at the faucet reaches a preset temperature, thereby saving water resources, and enabling users to directly use hot water by turning on the faucet, which is convenient to use.

Detailed ways

The utility model will be described in further detail below in conjunction with accompanying drawing and specific embodiment:

Example 1:

As shown in Figure 1, an intelligent water heater is characterized in that a heater 3 and a first temperature sensor 6 are arranged in the water tank 7, and a controller 4 and a display screen 5 are arranged on the outer wall of the water tank 7; Both ends are connected with the water tank 7 to form a water circulation path, and a circulating pump 12 is connected in series on the circulating water pipe 1; a flow sensor 2 is provided at the entrance of the circulating water pipe 1; An electric control water valve 9 is arranged on the top, and a second temperature sensor 8 is arranged at the entrance of the electric control water valve 9; the first temperature sensor 6, the second temperature sensor 8 and the flow sensor 2 are all connected to the controller 4; the heater 3, Both the circulation pump 12 and the electric control water valve 9 are controlled by the controller 4 . Described controller 4 is single-chip microcomputer or DSP. The first temperature sensor 6 is used to detect the water temperature of the water tank.

Description of working process:

When the user opens the water tap 11, a very small amount of water flows out. At this time, the flow sensor 2 can feel the flow change. At this time, the controller 4 can close the electric control water valve 9 to prevent the water from continuing to flow out, and the colleague starts the circulation pump 12; The hot water in the water tank first flows to the branch water pipe 10 until the second temperature sensor 8 detects that the temperature at the branch water pipe 10 reaches the preset temperature (such as 40 degrees), then the circulation pump 12 is turned off, and the electric control water valve is opened. 9. At this time, hot water comes out directly from the faucet 11. The display shows the current water temperature and prompt information.
