Technical Field

The utility model relates to a liquid heating system technical field specifically is a heating, water supply system that is used for no water tank fast heating pipeline machine or tap heater.

Background

With the improvement of social material and mental civilization construction, the requirements of people on the functions and the performances of products such as water dispensers, coffee machines, tea dispensers, water taps (including water purification taps) and the like are higher and higher, and particularly the requirements on the precision of water temperature and water quantity are higher.

Firstly, the water purifier can be used for filtering tap water through the ultrafiltration filter element and the RO membrane to obtain purified water for drinking, and the purified water flow of the conventional water purifier is generally 1-2.5L/min. The water dispenser comprises a water purifier 1 'and a quick heating pipeline machine 2', tap water firstly enters the water purifier for filtration and purification, and then the filtered pure water flows into the quick heating pipeline machine through a pipeline for heating. The existing fast heating pipeline machine in the market is a fast heating type water dispenser connected with a pressure drinking water source, and is very popular with consumers because of the advantages of low energy consumption in standby, high instant heating water temperature, no 'rolling water' and the like.

Secondly, the rapid heating pipeline machine 2 ' mainly comprises a water tank 3 ', a heating body 4 ', a water inlet pipe 5 ' and an electric control plate 7 ', the water inlet pipe 5 ' is communicated with the water tank 3 ', and a water inlet electromagnetic valve 6 ' is arranged on the water inlet pipe 5 ', as shown in the attached figure 4 of the specification. However, the water tank 3 ' is arranged in the quick heating pipeline machine, so that the volume of the whole machine of the water dispenser becomes larger, the water tank 3 ' is usually not sealed, and air with a large amount of harmful substances such as dust, bacteria and the like in the using environment of the water dispenser can enter the water tank, so that water in the water tank 3 ' contacts the air, pollution is caused, bacteria are bred, and the machine is not sanitary.

Thirdly, in order to realize accurate adjustment of temperature and water quantity, the pipeline water dispenser needs to be additionally provided with a water pump 8 ', the water inlet temperature is judged through an electric control board 7' according to the selected water outlet temperature and the selected water outlet quantity, then a PID control algorithm is adopted, a closed-loop control structure and a negative feedback control mode are used for timely adjusting a silicon controlled rectifier (or a relay) and a flowmeter, so that the heating body power and the water pump flow are adjusted, and the water outlet temperature and the water flow are accurately controlled

Fourthly, the electric heating faucet (including the water purification electric heating faucet) on the current market can not realize the accurate regulation of the flow of water because the influence of the water pressure of the tap water (the water purification machine) on the flow can not be overcome, and can not adopt a PID control algorithm, and can not regulate the power and the flow of a heating body, and the water temperature and the flow of the water can be accurately controlled.

The water inlet electromagnetic valve is arranged on the water inlet pipe to control the water inlet of the water inlet pipe, when a user needs water, the water inlet electromagnetic valve is started, purified water can flow into the heating body from the water inlet pipe, and when the user does not need water, the water inlet electromagnetic valve is closed; the setting of electrical control valve and flowmeter can control the inflow, because of the heating member when heating its inside water, it is long when needing certain heating, and the inlet tube is still intaking continuously this moment, and the inflow is great, when the flowmeter records discharge and reachs the setting value, then can control electrical control valve work, carry out the regulation of discharge, make the discharge of electrical control valve play water end reduce after the regulation, fast hot pipeline machine connects the purifier and forms complete water dispenser. The purifier does not have the water storage bucket a bit among the prior art, has the water storage bucket a bit, when using with the supporting use of purifier that does not have the water storage bucket, because of the purification discharge of purifier output is invariable, if the flow of taking the purification water is less than output purification discharge, the water purification chance is very frequent opens and stops, leads to the unable normal work of purifier, consequently needs the purification moisture reposition of redundant personnel of output. The backflow pipe is arranged, so that redundant purified water at the water inlet end of the electric regulating valve can be returned to the water inlet pipe of the water purifier, and the backflow pipe is provided with the one-way valve, so that unpurified water is prevented from flowing into the water purifying pipe from the backflow pipe, and the consumption of purified water is better controlled; the purpose that the pressure reducing valve is arranged at the water inlet end of the water purifier is to enable the water inlet pressure of the water purifier to be lower than the purified water end control pressure of the water purifier, so that the purified water flows back smoothly. When the water purifier has the water storage bucket, because of the water storage bucket can control the discharge water flow, so can seal the return pipe.

The utility model discloses a further setting: the electric regulating valve adopts a stepping motor to regulate the flow.

By adopting the technical scheme, the stepping motor is an electric motor which converts an electric pulse signal into corresponding angular displacement or linear displacement. When a pulse signal is input, the rotor rotates by an angle or moves one step, the output angular displacement or linear displacement is in direct proportion to the input pulse number, and the rotating speed is in direct proportion to the pulse frequency, so that the accuracy of regulating the flow by the rotating steps of the stepping motor is high.
