The specific embodiment
With reference to accompanying drawing, a kind of water heater comprises inner bag 2, water inlet pipe 16, outlet pipe 8, temperature sensor 14, the heater 13 that links to each other with control circuit, the sidewall of inner bag is a flexible wall, and the inner bag top is fixed on outer courage 1 upper wall, and heater and temperature sensor are installed on the balancing weight 15 of inner bag bottom; Between the intermediate cavity 7 of courage 1 and inner bag 2 and the inner bag water service pipe 3 is set outside,, the magnetic valve 4 link to each other with control circuit is installed on the water service pipe, the end that water service pipe is positioned at inner bag connects a flexible pipe 11 that may extend into bottom the inner bag.Inner bag connects a level sensor 9, and this level sensor links to each other with control circuit.Level sensor 9 comprises a coiling 10, and the end that winds the line is fixedlyed connected with the inner bag bottom, and the other end links to each other with coiler device.Coiler device is following structure:
Water flow sensing unit is installed on the outlet pipe, water flow sensing unit is following structure: establish guide pipe 32 in the water flow sensing unit, sliding sleeve 34 covers fit over outside the guide pipe and are connected on the guide pipe by flexible boot 33, be connected with switch case 29 by extension spring 30 with the magnet 35 of sliding sleeve end face jacking, the magnetic induction part 37 that cooperates with magnet (using Hall element in the present embodiment) is installed on the switch case.One overvoltage protection valve 12 is installed between inner bag and outside lining cavity chamber.Structure is as follows: establish taper bulge loop 45 on the spool 42, the spool outside is with stage clip 41, and the sealing ring 44 that matches with the conical surface of taper bulge loop is installed in the valve body 40, offers on the valve body and makes bulge loop end face and the extraneous inlet opening 43 that communicates, and sets out water hole 46 on the valve body.
One water-tight device is installed between heater and the power line, and described water-tight device is following structure:
Transit joint 84 1 ends are threaded with heating tube 86, and the transit joint other end is connected with clamp nut 83, and the clamp nut link outside of transit joint is provided with bulge loop 85, and the flexible protective casing 82 of power line 81 is pressed between the bulge loop outside and the clamp nut.
Control circuit can be provided with the time period and the water capacity of heating, insulation, by level sensor with the water level information input control circuit, by temperature sensor with the temperature information input control circuit, by the information input control circuit of water flow sensing unit with tap 5 switches, magnetic valve of installing on the water inlet pipe and the heater that is installed in inner bag bottom are connected with control circuit.
After the installation, running water enters water heater, and the air in the inside and outside courage is discharged.When the water capacity in the inner bag does not reach required capacity, magnetic valve on the water service pipe between inside and outside courage is opened, because the inner bag bottom is provided with balancing weight, outer courage hydraulic pressure is than inner bag height, water in the outer courage flows in the inner bag automatically, automatically descend at the bottom of the inner bag, the coiling that drives level sensor is elongated, therefore the wheel shaft of level sensor rotates, lance and contact-making switch in rotation process repeatedly bullet touch, with water capacity information input control circuit, when reaching when setting water capacity, control circuit is with the closed electromagnetic valve on the water service pipe, and inner bag stops into water.
In above-mentioned water inlet process, when the water capacity of inner bag reached certain value, control circuit made heater work, because temperature sensor has been installed in the inner bag bottom, after the inner bag water temperature reached setting value, heater only was incubated the water in the inner bag.
Tap is opened, and the information that water flow sensing unit is opened tap passes to control circuit, and control circuit is opened the magnetic valve on the water service pipe, because the effect of balancing weight, outer courage hydraulic pressure is than inner bag hydraulic pressure height, and the water in the outer courage flows in the inner bag automatically.Because the delivery port of flexible pipe is positioned at the inner bag bottom, when the water temperature that enters the inner bag bottom is transmitted than the water in low and the outside courage of inner bag bottom heat, inner bag bottom water temperature at first reduces, when water temperature is lower than the high temperature dot of the cooling extent of design temperature bottom the inner bag, heater work quits work after the inner bag bottom water is heated to setting value.
Along with the coolant-temperature gage that enters inner bag reduces gradually, heater can't be heated up the water of inner bag bottom, when the water temperature of inner bag bottom drops to the low warm spot of cooling extent of design temperature, closed electromagnetic valve, inner bag stop into water, and heater just can be soon be heated to design temperature with the water of inner bag bottom, at this moment, heater quits work, and magnetic valve is opened again, the inner bag water inlet.When water temperature is lower than the high temperature dot of the cooling extent of design temperature bottom the inner bag, heater is started working again, when water temperature continues to drop to the low warm spot of cooling extent of design temperature, closed electromagnetic valve, heater is heated to design temperature with water temperature again, so circulation, guarantee that the water in the outer courage constantly flows into inner bag, and it is warmed to design temperature in the most of the time of water discharge of water faucet, reach the purpose of constant-temperature effluent, thereby reduce the volume and the preheating time of water heater.
Be noted that because heat is conducted the water in the chamber between outer courage and the inner bag is common near the water temperature in the inner bag before tap is opened, near also variation in gradient of the water temperature the inner bag bottom is following.Because raising with temperature, the proportion of water reduces, always the higher water of temperature floats over top.When outer courage when inner bag is intake because the water inlet of water service pipe is located at the top of chamber again, the water that temperature is high is introduced into inner bag, along with the water in the chamber constantly flows into inner bag, its temperature also reduces gradually, and to the running water temperature.This just makes that the water in the outer courage almost can not get any energy.
Because it is littler than water yield to enter the water of inner bag, in use, always constantly close to the top at the bottom of the inner bag, the water in the inner bag is fewer and feweri, can be set in different water levels and carry out early warning, with the prompting user.When the inner bag water capacity drops to certain value, close heater, prevent xeothermic damage water heater, simultaneously magnetic valve is opened, at this moment the break-make of magnetic valve is not subjected to the Temperature Influence of inner bag bottom.At this moment, the cold water that enters inner bag is all extruded the hot water in the inner bag, makes that hot water is almost all utilized in the water heater because the rate of thermal water utilization of common water heater is lower, so the volume of this water heater reduce, thereby reduce preheating time, energy savings.
When inner bag continues to rise to when touching the top, inside and outside courage pressure reduction increases, and the discharge that enters inner bag increases, and till the inflow and water yield balance of inner bag, at this moment, the water of discharge is already near the temperature of running water, a working cycles end.
The balancing weight of this device is the pouring weight of a big quality, and purpose is the pressure reduction that produces inside and outside courage, as makes into to produce pressure reduction with the form of spring, and technological means is similar to the balancing weight of this device, and the purpose unanimity also should be considered as falling into protection scope of the present invention.
