Abstract

The utility model relates to an anti-absorbing shrunken device for water tank of solar energy water heater, consisting of an outer thimble and an inner exhaust pipe; the outer thimble is inverted, and an opening of the outer thimble is arranged in the water tank with a sealed pipe base bares outside; and the inner exhaust pipe crosses through the water tank with one end communicated in the outer thimble and the other end bares outside. The design of the utility model starts from improving the exhaust pipe structure of the solar energy water heater, preventing the water tank absorbing shrunken scrap phenomena from feculency and frost jamming of the vent pipe, avoiding the loss of exchanging water tank of the manufacturing companies, solving the interruptive trouble of water when the water hater in use. The utility model is novel and ideal and in a status of great practical need but less consumers.

Description

Solar water heater water tank preventing absorbing shrinkage device

It is the water tank preventing absorbing shrinkage device of the water heater of thermal source with the sun that the utility model relates to a kind of.

Solar water heater is a thermal source with free sunshine, saves energy cost and pollution-free and promote and day to contain.The water tank of solar water heater has water inlet, delivery port and exhaust outlet to communicate with the external world, cold water by water inlet pipe in water inlet enters water tank, vacuum heat collection pipe, vacuum heat collection pipe can make the cold water heating with the light (heat) of the sun, accumulates in the water tank, and hot water is used for the user through outlet pipe by delivery port.Cold water progresses into the process of water tank, also is the process that the air in the water tank is discharged by exhaust outlet gradually.Equally, the process that hot water is emitted from water tank also is the process that outside air progresses into water tank.So exhaust outlet is unobstructed, be the essential condition of the hot and cold water turnover of water tank.Yet, present exhaust outlet is exposed extraneous, freeze to stop up season in midwinter, the dirt phenomenon of blocking happens occasionally at ordinary times, if this moment, user's usefulness that puts hot water is then under the effect of outlet pipe water falling gravity, the air pressure in space is less than the water tank ambient pressure in the water tank, the drop of water is big more, and the air negative pressure of water tank is big more, scraps until inhaling water tank flat.It is not rarely seen inhaling flat accident.

The utility model is set about from improving exhaust pipe structure, solves blast pipe anti-clogging problem, reaches the generation of water tank preventing absorbing shrinkage phenomenon.To this, can realize by following measure: it is installed in water tank upper, exhaust pipe mouth is higher than the peak level of water tank, form by outer tube and inside exhaust pipe two large divisions, outer tube is inverted, and uncovered being installed in the water tank is exposed to the external world at the bottom of the pipe of sealing, one end of inside exhaust pipe leads in the outer tube, and the other end is exposed to the external world.

The utility model also can come perfect by following measure: outer tube is selected vacuum sleeve for use, and inside exhaust pipe is selected straight tube for use.

Fig. 1 is the utility model structural representation.

Fig. 2 is a solar water heater main part structural representation.

The utility model is below in conjunction with embodiment and contrast the accompanying drawing work as detailed below: general solar water heater water tank is a metal shell, has water inlet 1, blast pipe 5, delivery port 6 to communicate with the external world, and water tank 2 walls are outward heat-insulation layer, and outer again is metal shell.The utility model also blast pipe with general solar water heater is the same, is installed in water tank 2 tops, and its exhaust pipe mouth is higher than water tank 2 peak levels (if any water supply tank 3, also should be higher than the peak level of water supply tank 3).The preventing absorbing shrinkage device is made up of with inside exhaust pipe 5 two large divisions outer tube 4, outer tube 4 inversions, and uncovered being installed in the water tank 2 is exposed to the external world at the bottom of the pipe of the outer tube 4 of sealing, and an end of inside exhaust pipe 5 leads in the outer tube 4, and the other end is exposed to the external world.Both optimal ways are, outer tube 4 is selected nature of glass vacuum sleeve for use, help fine heat absorption, and cold night is antifreeze.Be the cost-saving, just available simple glass pipe or metal tube.Outer tube pipe Φ 45-60mm; Inside exhaust pipe 5 is selected metal straight pipe for use, Φ 15-25mm, and the upper end is in outer tube 4, and the lower end is exposed extraneous below water tank.The following mouth down of this inside exhaust pipe 5 is exposed to be preferred plan, stops up up with towards the easy contamination thing of side and rainwater.Will be down, straight tube gets final product.Two pipes, 4 and 5 usefulness sealing rings are installed on the water tank 2.

The peak level that is higher than water tank 2 (or water supply tank 3) because of the gas outlet, dirt can not enter the suitable for reading of inside exhaust pipe 5 and stops up in water and the water, the enclosure that 4 pairs of inside exhaust pipes 5 of outer tube are arranged, extraneous dirt can not drop on the suitable for reading of inside exhaust pipe and stop up, when the hot water in the water tank 2 does not use up, because of the effect of the outer heat-insulation layer of water tank 2 housings, the water in the outer tube 4 is not even can freeze season in midwinter yet.If the water in the water tank 2 is the cold water that just injects, then under heat-insulation layer (foam layer) effect, through also being difficult to reduce to below freezing and icing general cold night, might be at the fraction water in the outer tube 4 because of nearly extraneous easily circuitous cold freezing, produce obstruction in short-term, then daybreak a little Exposure to Sunlight promptly change, be cold water still more in the water tank, nobody use of going to discharge water.This installs the living blast pipe obstruction of just utmost point difficult labour, discharging water makes water tank inhale flat phenomenon so had.

The utility model is set about from the structure of improving blast pipe, makes blast pipe avoid dirt and freezing obstruction, does not efficiently solve because of exhaust does not freely cause water tank to inhale the flat problem of scrapping.
