It should be noted that first level filtering device should be higher than that the installation position of the first front tube and the second front tube in the mounting arrangements of equipment It sets, continues to rise according to Communicating device principle by purified water energy is enough in this way, until by relay pump or cold water electrical water outlet pump It pumps.

When hot water is needed, relay pump can be started by heating controller, can be set according to the volume of electric heating cavity What meter relay pump was opened every time pumps duration, such as starting pumps 15 seconds every time.Electric heating tube is then opened, to electric heating cavity Interior water is heated, and the real time temperature of temperature sensor senses water is then passed through, and when reaching preset value, electric heating tube stops Heating.Pressing hot water push type outlet valve is opened, starting hot water electrical water outlet pump enables hot water is suitable to be flowed out by hot water outlet pipe It is quoted with connecing.

When needing cold water, cold water push type outlet valve is pressed, starts cold water electrical water outlet pump, it can will be in the first front tube Purified water be pumped into cold water outlet pipe and flow out.

The present apparatus in use for some time, can carry out automatically cleaning operation.It can be arranged in the bottom of " u "-shaped pipe and drain Valve.The liquid in device is emptied using the drain valve.Water source is opened, until pressing hot water push type outlet valve and cold water pressing Formula outlet valve all has water discharge out of hot water outlet pipe and cold water outlet pipe, i.e., is each filled with water in each component of device.It opens Ozone generator, and open rotating electric machine, after enabling ozone and water be sufficiently mixed from out of hot water outlet pipe and cold water outlet pipe all There is water discharge, after persistently draining one end time, closes hot water push type outlet valve and cold water push type outlet valve, and close water Source.Drain valve is then opened, the residual liquid in device is discharged.It is again turned on water source, is contained remnants in device by water flow There is the solution of ozone to rinse well, be again switched off water source, after opening drain valve emptying raffinate, that is, completes purification cleaning process.

The present apparatus carries out automatically cleaning using ozone, has the following characteristics that

1. enzyme needed for ozone energy oxygenolysis bacterium endogenous glucose keeps bacteria inactivation dead.

2. directly destroy their organelle and DNA, RNA with bacterium, virus function, make the metabolism of bacterium by It destroys, leads to bacterial death.

3. penetrating cell membrane tissue, intrusion is intracellular, acts on the lipoprotein and internal lipopolysaccharides of outer membrane, sends out bacterium It gives birth to penetrating sex distortion and dissolves death.

Ozone sterilization is bacteriolyze grade method, sterilization thoroughly, noresidue, broad-spectrum, can kill bacterial propagule and gemma, Virus, fungi etc., and botulin toxin can be destroyed.In addition, ozone also has extremely strong killing effect to mould.Ozone is due to steady Qualitative difference can voluntarily be decomposed into oxygen or single oxygen atom quickly, and single oxygen atom can voluntarily be combined into oxygen molecule, be not present Any toxic residua, so, ozone is a kind of free of contamination disinfectant.

The ozone generator is the mature prior art, and it is smelly that hundred happy health FQ-301 integrations can be used in the present embodiment Oxygen Generator, principle are documented in that Patent No. 200410079317.5, entitled " pyrocondensation wraps tightly electrode ozone by detailed In the patent of invention of generator tube ", details are not described herein.

It in this patent, is not main innovation point of the invention about the structure of electric heater unit and application method, because This is not limited to structure described in the present apparatus, can be substituted completely using heating means in the prior art.The relay pump, Electric heating tube and temperature sensor respectively can be controlled individually, can also be all connected with heating controller, can be controlled by heating controller Start and stop, electric heating tube and the start and stop of relay pump processed and the real time temperature of displays temperature sensor.It is carried out by heating controller total Control, can realize according to editor PLC control circuit in the prior art.Since the control mode is not main wound of the invention It is new, therefore it is not limited to structure described in the present apparatus, it can be substituted completely using heating means in the prior art.

The above descriptions are merely preferred embodiments of the present invention, is not to make other forms to the utility model Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent The equivalent embodiment of variation.It is all without departing from the content of the technical scheme of the utility model, according to the technical essence of the utility model pair Any simple modification, equivalent variations and remodeling, still fall within the protection model of technical solutions of the utility model made by above embodiments It encloses.
