Abstract

The utility model relates to an automatic cleaning device for a solar water heater. A sheath pipe communicated with a square pipe of a water tank is arranged in a vacuum heat collecting pipe. A water shooting head is arranged at the front end of the sheath pipe. The front end of a core pipe in the sheath pipe extends out of the sheath pipe. A soil absorbing nozzle is clung to the bottom of the heat collecting pipe. The end of the soil absorbing nozzle is communicated with the water tank. A drainage spray head is correspondingly connected to a drainpipe in the water tank. A blowoff valve positioned at the tank bottom on the middle part of the water tank is connected to an overflow pipe. A change valve is connected with a water inlet pipe, the square pipe of a water tank and the water outlet pipe. The utility model is used for cleaning dirt in the heat collecting pipe and the water tank, improving water quality, and enhancing heat absorbing rate. The utility model is an ideal device for cleaning the solar water heater.

Description

The automatic flushing device of solar water heater

The utility model belongs to mechanical field, is specifically related to a kind of structure of automatic flushing device of solar water heater.

After solar water heater uses by dress, through a period of time, dirt will appear in its vacuum heat collection pipe and the water tank, and the dirty phenomenon of the water supply pipe scale collection of especially newly-built building is even more serious, so just cause: one, the vacuum heat collection pipe heat absorption rate is low, and Heat-collecting effect is poor; Two, the water quality inferiority in the water heater, the people is not drinkable; Three, easily grow mushroom.

The purpose of this utility model is: design a kind of automatic flushing device of solar water heater, clean and eliminating vacuum heat collection pipe and the interior dirt sediment of water tank, make water quality pure, improve the thermal-collecting tube heat absorption rate, keep good Heat-collecting effect.

The purpose of this utility model is achieved in that the sleeve pipe that is provided with the belt carcass pipe that is communicated with square tube in the water tank in the vacuum heat collection pipe, the sleeve pipe front end has the jetting head, core pipe front end is longer than sleeve pipe, end openings is in water tank, core pipe front end has soil pick-up to chew, drainpipe two ends in the water tank connect delivery spout relatively, and reversal valve connects water inlet pipe, water tank square tube and drainpipe, and blowoff valve connects water tank bottom.

Connect power supply, start reversal valve and blowoff valve, running water enters sleeve pipe, cleans tube wall through jetting head water spray, and soil pick-up is chewed the assembly dirt, drains in the water tank through the core pipe, and delivery spout is washed dirt to blowoff valve again, discharges through overflow pipe.

Fig. 2 is the utility model cutaway view

Fig. 3 is the utility model jetting head schematic diagram

Among the figure: 1 sealing ring, 2 thermal-collecting tubes, 3 sleeve pipes, 4 core pipes, 5 jetting heads, 6 soil pick-ups are chewed, 7 blowoff valves, 8 reversal valves, 9 water tank square tubes, 10 drainpipes, 11 overflow pipes, 12 booster pumps, 13 water inlet pipes, 14 delivery spout, 15 supports, 16 water tanks

Introduce implementation method of the present utility model below in conjunction with accompanying drawing:

In vacuum heat collection pipe 2, be provided with the sleeve pipe 3 of belt carcass pipe 4, sleeve pipe 3 front ends have jetting head 5, terminal water tank square tube 9 in sealing ring 1 joining water box 16, long core pipe 4 is positioned at sleeve pipe 3, its terminal water flowing case 16, the soil pick-up that is positioned at core pipe 4 front ends is chewed 6 bottoms of pressing close to thermal-collecting tube 2, sleeve pipe 3 core pipes 4 are fixed on the support 15 that is positioned in the water tank 16, delivery spout 14 is connected the two ends of the drainpipe 10 in the water tank 16 relatively, on blowoff valve 7 connects at the bottom of the water tank 16 middle part casees, reversal valve 8 connects water tank square tube 9, drainpipe 10 and water inlet pipe 13 have booster pump 12 on the water inlet pipe 13, overflow pipe 11 connects blowoff valve 7.

Connect power supply, electronic reversal valve 8 and blowoff valve 7 are opened, running water enters sleeve pipe 3 by water inlet pipe 13, reversal valve 8, water tank square tube 9, be sprayed onto tube wall through jetting head 5, the soil pick-up that is positioned at pipe bottom is chewed 6 and is assembled dirts and drain into water tank 16 through core pipe 4, after reversal valve 8 displacements, the running water changed course enters drainpipe 10 by water inlet pipe 13, reversal valve 8, shower nozzle 14 washes dirt to blowoff valve 7, after overflow pipe 11 is discharged, pipe pressurizing pump 12 is used to improve hydraulic pressure makes cleaning performance better, and cleaning finishes, turn off power supply, it is normal that water heater recovers.

The utlity model has following advantage: 1, improve the heat absorption rate of vacuum heat collection pipe, Keep good Heat-collecting effect; 2, improve water quality, make the use of solar water heater clean Only; 3, the double blow-off pipe of doing of overflow pipe, one tube multipurpose; It is 4, convenient by dress, simple to operate, It is the ideal device of cleaning solar.
