Description

A bathroom water saving system

technical field

The utility model belongs to a bathroom system, in particular to a bathroom water-saving system, which can be applied in school dormitories.

Background technique

At present, more and more school dormitories have independent toilets, and each dormitory building is equipped with a boiler room. Students can take hot water baths directly in the dormitory, which improves the quality of school life. But take a bath every time, because there is cold water or outdoor air temperature reason in the water pipe, water temperature just can reach the temperature standard of bathing after must releasing a large amount of cold water, this part cold water of releasing directly flows into sewer, has caused the waste of water resources. Moreover, there are many students in the school, and the bathing time is not fixed every night. Especially in winter, students living on higher floors need to release a lot of cold water every time they take a bath, which is a serious waste of water resources.

Therefore, those skilled in the art urgently need to provide a sanitary water-saving system with simple structure and low cost.

Utility model content

Aiming at the deficiencies in the above-mentioned prior art, the utility model provides a sanitary water-saving system with simple structure and low cost. The system is suitable for places with a large number of water users such as school dormitories and factory areas, and can also be used in homes.

In order to achieve the above object, the utility model adopts the following technical solutions:

A bathroom water-saving system, comprising a shower head, a hot water pipe connected to the shower head, a toilet, and a water tank. The hot water pipe is provided with a temperature sensor, and the water outlet of the hot water pipe is connected to the inlet of a two-position three-way solenoid valve. The water outlet is connected, one water outlet of the two-position three-way solenoid valve is connected with the water tank, the other water outlet is connected with the shower head, and the water tank is connected to the toilet through the water outlet pipe; the temperature sensor and the two-position three-way solenoid valve are all connected with the water tank. MCU electrical connection.

Preferably, the single-chip microcomputer is connected with a digital display.

Further, the single-chip microcomputer is placed in a waterproof airtight plastic casing.

Preferably, a valve is provided on the water outlet pipe connecting the water tank to the toilet.

The beneficial effects of the utility model are:

When the water-saving system of the utility model starts to take a bath, the temperature sensor first detects the water temperature in the hot water pipe, and the digital display displays the current temperature; then the single-chip microcomputer controls the two-position three-way solenoid valve. It flows into the water tank for flushing the toilet; when the water temperature meets the requirements for bathing, hot water flows out from the shower head for bathing.

The water-saving system can store the cold water released before bathing in the water tank, reduce the waste of the part of cold water, improve the water usage rate, and thus achieve the purpose of water saving. The system is low in cost and easy to implement, and can be applied to occasions with a large number of water users such as school dormitories and factory areas, and can also be applied to families, and has extensive social and economic significance.

detailed description

The technical solution in the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. The following examples are only used to illustrate the technical solution of the utility model more clearly, but not to limit the protection scope of the utility model.

As shown in Figure 1, it is a bathroom water-saving system, which includes a shower head 3, a hot water pipe 1 connected to the shower head, a toilet 4, and a water tank 2. The hot water pipe 1 is provided with a temperature sensor 5, and the hot water pipe 1 The water outlet is connected to the water inlet of the two-position three-way solenoid valve 6, one water outlet of the two-position three-way solenoid valve 6 is connected to the water tank 2, and the other water outlet is connected to the shower head 3, and the water tank 2 is connected to the toilet 4 through the outlet pipe. A valve 9 is provided on the water outlet pipe connecting the water tank 2 to the toilet 4 . The temperature sensor 5 and the two-position three-way electromagnetic valve 6 are all electrically connected to the single-chip microcomputer 8; the single-chip microcomputer 8 is also connected with a digital display 7. In addition, the single-chip microcomputer 8 is placed in a waterproof airtight plastic casing.

The working principle of the system will be described in detail below in conjunction with the accompanying drawings.

As shown in Figure 2, when starting to take a bath, the temperature sensor 5 detects the water temperature in the hot water pipe 1, and the digital display 7 displays the current temperature. According to the needs of use, the ideal bath water temperature can be preset in the single-chip microcomputer 8, and the temperature sensor 5 transmits the current water temperature to the single-chip microcomputer 8, and the single-chip microcomputer 8 judges the actual water temperature and the ideal water temperature, and controls the two-position three-way solenoid valve 6 to make corresponding processing: when When the water temperature is lower than the set temperature, the single-chip microcomputer controls the valve connected to the water tank to open, and the water in the hot water pipe 1 flows into the water tank 2 to flush the toilet 4; when the water temperature meets the bathing requirements, the single-chip microcomputer controls the valve connected to the shower head to open, and the hot Water flows out by shower head 3, is used for having a bath.

The above description is only the preferred embodiment of the utility model, and it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the utility model, some improvements and deformations can also be made. And deformation should also be regarded as the protection scope of the present utility model.
