Background technology

The present invention is applied to commercial electric water-boiling device.Original commercial electric water-boiling device is most of to adopt ball-cock assembly control to intake, and hot and cold water mixes, and power consumption is high, and it is long to connect the boiling water equal time; The commercial electric water-boiling device of part adopts the solenoid valve base water inlet, because the thermal treatment zone and storage area consubstantiality, thermal treatment zone volume is excessive; Each inflow is too much, and the impulsive force of water is big, and inhomogeneous; Cold and hot mixing water volume is excessive, still can not solve hot and cold water mixed problem, and energy-saving effect is not obvious; Portioned product rapier control heating because incrustation scale concentrates on the METAL HEATING PROCESS rapier, influences electric conductivity, causes control malfunctioning, need often pull down and clean or change, and influences machine product quality and reputation, has shortened the service life of complete machine.

Summary of the invention

Call for responding national energy-saving and emission-reduction; Thoroughly solve hot and cold water mixed problem, more healthy, energy-conservation drinking water is provided, improve commercial electric water-boiling device normal operation ability; Product structure, control performance aspect to original commercial electric water-boiling device are improved, upgrading.

The technical scheme that its technical problem that solves the utility model adopts is: 1. the commercial boiler thermal treatment zone (being the hot and cold water mixed zone) heated little water tank instead and place centre position (like Fig. 2-22), bottom, and set up two temperature sensors (like Fig. 1-8,9) to measure temperature.2. install step-by-step movement DC pulse magnetic valve (like Fig. 2-10) additional, make water evenly inject heating little water tank (like Fig. 2-22), heating rapier automatic flushing device 3. is set (like Fig. 4-24-27).Beneficial effect: the beneficial effect of the utility model technology is, solved hot and cold water mixed problem, and the health energy-saving drinking water is provided, and rationally utilizes the space, and is energy-saving and cost-reducing, strengthened electric conductivity, improved commercial electric water-boiling device normal operation ability.

The principle summary:

Connect water power source impulse electromagnetic valve (like Fig. 2-10) and get electric water inlet, to heating little water tank (like Fig. 2-22), when liquid level touches the heating rapier (like Fig. 2-11); Through automatic control system; Electric heater (like Fig. 3-6) gets electrical heating, and this moment, Pulse Electric valve (like Fig. 2-10) dead electricity stopped into water, gets intake the electric second time (about 1-2 liter) when water temperature reaches 85 degree-99 degree (can adjust) Pulse Electric valves (like Fig. 2-10); When reaching 85 degree-99 degree, temperature intakes for the third time, and the like.When storage tank (like Fig. 2-19) liquid level touched anti-overflow shutdown rapier (like Fig. 2-12), autostop got into constant temperature, keeping warm mode.(like Fig. 4-24-27), on rapier, install ball float brush (like Fig. 4-26) additional, the boiling that utilizes water level to move up and down with water is used as power heating rapier automatics, reaches the purpose of automatic cleaning, makes it keep excellent conducting performance.

The specific embodiment

For enjoying the low-carbon (LC) life, build energy-saving new society, we are according to the standard of CQC3133-2011 " the energy-conservation authentication techniques standard of commercial electric water-boiling device "; To structural behaviour, the control system of commercial electric water-boiling device, implemented utility model invention 1. the little water tank of heating has been set, and placed the centre position (like Fig. 2-22) of bottom; Dwindle the cold and hot mixing water volume in the thermal treatment zone, and to set up both centre-to-centre spacing of two temperature control sensors (like Fig. 1-8,9) be 25mm, display screen sensor (like Fig. 1-8) is the boiling water displays temperature; Constant temperature 99 degree,, this is provided with invariable; So proof, cold water does not mix with boiling water, is pure boiling water.Heating-up temperature sensor (like Fig. 1-9) temperature can be adjusted arbitrarily according to display screen numerical value between 85 degree-99 degree, when water temperature reaches this numerical value, begins water inlet, does not reach setting value, does not intake.2. install additional step-by-step movement DC pulse magnetic valve (like Fig. 2-10) with water under pulse condition evenly heating inject little water tank (like Fig. 2-22), purpose is to make that into water is steady, reduces water impact; Each water inlet is controlled between the 1-2 liter, reduces the combined amount of hot and cold water, and above 50mm sets up water fender at display screen sensor (like Fig. 1-8); Make boiling water and mixing water secondary isolation, water nozzle is installed at the above 100nn of water fender place; According to the heat principle that makes progress, guarantee that the water that water nozzle flows out is pure boiling water more than 99 degree.3. heating rapier automatic flushing device is set (on rapier, installs the ball float brush additional like Fig. 4-24-27); The boiling that utilizes water level to move up and down with water is used as power; Reach the purpose of automatic cleaning, make it keep excellent conducting performance, improve the normal operation ability of electric water-boiling device.Through the invention of above three utility models technology, product is put on market, at aspect such as healthy, energy-conservation, quick, obtains consumer's favorable comment, has increased the market share, has located the leading position already going together, and has vast market prospect.
