Abstract

The invention relates to the field of public water boilers, in particular to an intelligent water boiler applied in public places such as schools, institutions, hotels, hospitals and markets. The intelligent water boiler comprises a water outlet pipe, a water storage tank and a water inlet, wherein a flowmeter is mounted on water outlet pipe; a microprocessor, a pressure sensor and a storage are mounted in the water storage tank; an electromagnetic valve is mounted at the water inlet; the output signal of the flowmeter is subjected to AD sampling by the microprocessor and then is transmitted to the storage to store; the pressure sensors monitors the amount of the boiling water; data is transmitted to the microprocessor constantly; and the microprocessor controls the electromagnetic valve according to the water using condition of the previous period. The intelligent water boiler can adjust the work state of the water boiler according to the using law of the boiling water, so that the water boiler has the memory function, the water boiler can work with experience, each water boiler can work according to the using condition, the energy is saved, and the output water is close to the temperature of the boiling water.

Description

A kind of intelligent boiler

Technical field

What the present invention relates to is public boiler field, is specifically related to a kind of intelligent boiler that uses in public places such as school, public institution, hotel, hospital, markets.

Background technology

Public boiler is generally a lot of people boiling water is provided, and power is high, and capacity is large.Its advantage has also been brought its shortcoming, and this large-scale boiler volume is large, the insulation that is not easy to do, even claim on the market the boiler that has added heat-insulation layer, burned boiling water also can make their tank surface have a touch with and will scald one's hand, constantly at outside distribute heat.Some boilers all the time all near the temperature of boiling water, have heat insulation function for the water that guarantees to pick out, and its principle is exactly constantly heating, has caused the waste of the energy.

The boiler that use in public place generally has certain periodicity and regularity in use, night, come off duty during, be all unmanned water during festivals or holidays, this is in idle state by boiled water with regard to having caused in the boiler in a large number, and heat is by in vain waste.Just in by day use, also there is the water height peak period at last, such as the people of water receiving during the boiler break that uses in the school instruction building is many, the people of school session water receiving is fewer, has so just caused a lot of burned boiling water of school session to be in radiating state.

Left unused boiling water in boiler through after a while heat radiation, make tea than being fit to, the use such as make coffee is washed one's face and rinsed one's mouth if be used for, washing clothes etc. needs to use the place of hot water, we more do not wish originally by boiled water in boiler through having lost a lot of heats after heat radiation.

Summary of the invention

The invention provides and a kind ofly can automatically regulate duty, along with regulate constantly the intelligent boiler of the amount of heating up water in the difference of different time water consumption.

The present invention is achieved in that

The present invention includes outlet pipe, storage tank, water inlet, at outlet pipe, flowmeter is installed, microprocessor, pressure sensor and memory are housed in storage tank, water inlet is equipped with magnetic valve, the output signal of flowmeter is delivered to memory and is preserved after microprocessor AD sampling, the minable water yield of pressure sensor monitoring boiling, data send microprocessor constantly to, and microprocessor was controlled magnetic valve according to the water situation in a upper cycle.

Beneficial effect of the present invention is:

The present invention can realize regulating according to the rule of using boiling water the duty of boiler, makes boiler with memory function, works by rule of thumb, and the energy has been saved in the situation work that each boiler all is used according to self, and water outlet is more near boiled water temperature.

Description of drawings

Fig. 1 is theory diagram;

Fig. 2 is schedule of classes and times;

Fig. 3 is that Mon-Fri boiling water every day uses quantitative statistics;

Fig. 4 is boiling water use quantitative statistics on Sunday Saturday.

The specific embodiment

Microprocessor can use 51 single-chip microcomputers or MSP430 chip microcontroller.

AD does not need very high precision, and the self-contained analog-digital converter of microprocessor just is enough to satisfy the demands.

Memory can be used flash, 16,000,000 capacity.

Illustrate by reference to the accompanying drawings:

Suppose that this boiler uses in teaching building, the information setting of record is a week, supposes that capacity is 30 liters, and duty is divided into 10 liters of three class, 20 liters, 30 liters, is denoted as respectively 1,2,3 grade.

Microprocessor is controlled magnetic valve in conjunction with the data of pressure sensor feedback according to the water consumption information in a nearly week that monitors, and makes boiler in the different periods, different duties be arranged.Such as will make boiler be operated in 2 grades the time, microprocessor can be learnt current boiled water tank moisture storage capacity by pressure sensor, reaches or during greater than 20 liters, just controls the closed electromagnetic valve water inlet pipe, when being less than 20 liters, just opens water inlet pipe.

Mon-Fri water situation is basic identical as shown in Figure 3,7 select 22 select between the water height appear at times before class after and break, all the other times also have certain water consumption at random, between 22 o'clock to 7 o'clock, water consumption is almost nil.We can allow microprocessor control like this duty, are operated in 3 grades between tailend to the peak in front 20 minutes at water use peak, are operated in 1 grade between 22 o'clock to 7 o'clock, early 2 grades of all the other time services.

Select Sunday 7 Saturday 22 select between water relatively disperse, but there is no the situation of peak water, can be operated in 2 grades, between 22 o'clock to 7 o'clock water consumption the same with Mon-Fri be also almost nil.

Claims

1. intelligent boiler, comprise outlet pipe, storage tank, water inlet, it is characterized in that: at outlet pipe, flowmeter is installed, microprocessor, pressure sensor and memory are housed in storage tank, water inlet is equipped with magnetic valve, and the output signal of flowmeter is delivered to memory and preserved after microprocessor AD sampling, the minable water yield of pressure sensor monitoring boiling, data send microprocessor constantly to, and microprocessor was controlled magnetic valve according to the water situation in a upper cycle.
