Abstract

The utility model relates to a water fountain cold-hot water separating dying prevention device, which belongs to an electric heating boiled water device, particularly a device for preventing the mixing of hot water and cold water and the dry burning of a water drinking device. The bottom of a water storage box is provided with a water level switch which is connected with a power supply and the bottom of the water storage box is also provided with a conduit. A water storage zone of the conduit is provided with a pipeline heater and a one-way valve is arranged on one end of the conduit. The other end of the conduit is led to a water heating inner liner, and a water level control switch, a temperature control device and an inner liner heater are respectively arranged in the heating water inner liner. The utility model has the advantages of simple structure and automatic protection of water off, when hot water is taken, cold water can be ensured not to be mixed.

Description

The water fountain hot and cold water separates anti-dry burning device

Technical field

The utility model belongs to electricallly heated water boiling vessels, particularly can prevent the hot and cold water mixing of water fountain and the device of dry combustion method.

Technical background

The boiler of traditional water dispenser is to be heated up water by storage tank and collaborative the finishing of the inner bag of heating up water, when heat water valve is opened when discharging water, the cold water of storage tank also can enter the inner bag of heating up water thereupon, the formation hot and cold water mixes, influenced boiling water temperature wherein, the minable water yield of taking is immediately reduced, make tea simultaneously or coffee is made troubles for many people.Though this water dispenser has anti-dry burning device, still can not continue under the situation of water to heat a period of time having, when reaching uniform temperature, the inner bag dry combustion method just understands deenergization.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of improved water fountain hot and cold water and separates anti-dry burning device, and simple in structure, anhydrous automatic protection does not have cold water in the time of can guaranteeing heat-obtaining water and sneaks into.

Solving the scheme that technical problem of the present utility model adopts is: in the storage tank bottom water level switch that is connected on the electric power loop is installed, conduit also is equipped with in the storage tank bottom, pipeline heater is equipped with in the water zone of conduit, check valve is housed on conduit, the conduit other end feeds the inner bag of heating up water, and level control switch for water, temperature controller and inner bag heater are housed respectively in the inner bag of heating up water.

During use, water level switch has guaranteed that storage tank need reach certain water level, and power supply just can be connected, otherwise just outage automatically; During pipeline heater work, make the water expanded by heating in the conduit, flow in the inner bag of heating up water, the check valve of adorning on the conduit then can stop hot water to storage tank direction stream, thereby has hot water to flow to continuously in the inner bag that guaranteed to heat up water; When the water level in the inner bag of heating up water reaches certain height, level control switch for water is just started working, and cut off the power supply of pipeline heater simultaneously, at this moment no longer include the current inner bag that advances to heat up water, temperature controller cut off electric power loop when water was boiled, so just guaranteed to heat up water and more high temperature boiling water has been housed in the inner bag, and stopped the possibility that cold water enters fully.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model.

Each label is represented successively among the figure: storage tank 1, maximum water level 2, water level switch 3, check valve 4, pipeline heater 5, conduit 6, blast pipe 7, level control switch for water 8, temperature controller 9, the inner bag 10 of heating up water, inner bag heater 11.

The specific embodiment

Referring to Fig. 1, in the bottom of storage tank 1 water level switch 3 is installed, have only when the water level in the storage tank 1 reach a certain height, water level switch 3 is just connected power supply, and water level is lower than certain position or just auto power off when anhydrous.The conduit 6 that feeds the inner bag 10 of heating up water is equipped with in storage tank 1 bottom, wherein conduit 6 some zone are higher than storage tank 1 maximum water level 2, thereby the peak at conduit 6 has formed the water district to storage tank 1 bottom, pipeline heater 5 is loaded on the water zone of conduit 6, to the conduit 6 between the storage tank 1, the check valve 3 that leads to the inner bag 10 of heating up water is housed at pipeline heater 5, when water is heated and expands, is ended by check valve 3, the inner bag 10 of heating up water can only be flowed to, storage tank 1 can not be blowed back into.Level control switch for water 8, temperature controller 9 and inner bag heater 11 are housed respectively in the inner bag 10 of heating up water, when anhydrous in the inner bag 10 of heating up water or water level hang down, level control switch for water 8 is connected pipeline heater 5, close inner bag heater 11 simultaneously, prevent the dry combustion method phenomenon, and when the water in the inner bag 10 of heating up water was filled it up with, level control switch for water 8 was changed again inner bag heater 11 is connected, simultaneously blanked-off pipe channel heater 5; 9 of temperature controllers can be cut off the electricity supply energy savings when water is opened; Inner bag heater 11 is loaded on inner bag 10 bottoms of heating up water, and can guarantee that water is by boiled fully.In order to obtain preferably to the inner bag heat supply water effect of heating up water, conduit 6 peaks of this device should be higher than maximum water level 5mm～50mm, and hypertonia in the inner bag of heating up water in order to prevent to heat up water also is connected with a blast pipe 7 on the top of storage tank and the inner bag of heating up water.

Referring to Fig. 2, the level control switch for water 8 of this device is three joints, two station switches, promptly a binding post is connected to the power supply total loop, a station joint connects inner bag heater 11, another station joint is connected on the pipeline heater 5, then inner bag heater 11 and the pipeline heater 5 power supply total loop that inserts in parallel again.Temperature controller 9, water level switch 3 all insert in the main line of power supply, therefore can prevent that dry combustion method from appearring in pipeline heater and inner bag heater.
