Abstract
The utility model relates to a vacuum tube solar water heater which comprises a hot water tank and a vacuum tube; the hot water tank is provided with a water inlet and outlet pipe; a main drainage pipe is arranged in the hot water tank, and the main drainage pipe is communicated with the water inlet and outlet pipe; and a branch drainage pipe is arranged in the vacuum tube, and one end of the branch drainage tube is communicated with the main drainage tube. An auxiliary drainage pipe is arranged between the vacuum tube and the hot water tank; and one end of the auxiliary drainage pipe is arranged in the vacuum tube and the other end thereof is arranged at the bottom part of the water tank. The utility model provides a drainage-type vacuum tube solar water heater which can provide more hot water under the same conditions, and is safer and healthier.
Description
Technical field
The utility model relates to a kind of solar thermal collector.Be specifically related to a kind of vacuum tube solar heating element.
Background technology
Ordinary vacuum tube solar water heater on the present China market, the hot water in the vacuum tube can only reside in the vacuum tube in use, can't emit for the user and use, and makes that the practical efficiency of solar vacuum-tube water heater is low; In addition in the harder area of water quality, generate incrustation scale in the solar water heater easily, the ditch of generation is attached to making the endothermic effect of vacuum tube reduce on the vacuum tube tube wall, and then causes the water in the solar water heater not hot; This external northern frore area, winter temperature is low, and the surplus water capacity in the vacuum tube is easily frozen, can vacuum tube is freezing.
The utility model content
The utility model is at the deficiencies in the prior art, and a kind of more hot water, safer, more healthy drainage type solar vacuum-tube water heater of can providing under the same conditions is provided.
The utility model is achieved through the following technical solutions:
A kind of solar vacuum-tube water heater comprises heat storage water tank, vacuum tube, and heat storage water tank is provided with water inlet pipe and water outlet pipe, establishes drainage in the heat storage water tank and is responsible for, and the drainage person in charge is connected with water inlet pipe and water outlet pipe; Be provided with the drainage arm in vacuum tube, drainage arm one end is responsible for drainage and is connected.
A kind of solar vacuum-tube water heater is provided with secondary drainage tube between described vacuum tube and the heat storage water tank, an end of secondary drainage tube is positioned at vacuum tube, and the other end is positioned at water tank bottom.
A kind of solar vacuum-tube water heater, described drainage arm one end are responsible for drainage by straight coupling and are connected.
The end mouth of pipe that a kind of solar vacuum-tube water heater, described drainage arm are positioned at the vacuum tube bottom is the opening of cutting sth. askew.
A kind of solar vacuum-tube water heater, an end of described secondary drainage tube is positioned at the vacuum tube opening part.
During use water nozzle is arranged on and is lower than complete machine lowest water level place, just can the water in heat storage water tank and the vacuum tube all be drawn by drainage tube.When water level in the heat storage water tank was higher than the vacuum tube mouth of pipe, hot water elder generation vacuum tube flowed into the drainage arm, entered drainage and was responsible for the arrival intake-outlet; When water level in the heat storage water tank was lower than the vacuum tube mouth of pipe, the water in the heat storage water tank flowed into vacuum tube by secondary drainage arm, entered drainage through the drainage arm again and was responsible for the arrival intake-outlet; After treating that the whole drainages of hot water finish in the heat storage water tank, the hot water in the vacuum tube is all drawn through drainage tube again.The utility model compared with prior art, water in the water heater all can be drawn, it is about 25%～35% so under equal conditions can to make reality can have the hot water amount to increase, and the unit are of its complete machine is effective that heat also can be significantly improved, thereby improves solar energy utilization rate.Water in the vacuum tube is all drawn, even at extremely frigid zones, vacuum tube can be because of not icing and freezing yet, thereby make the anti-freezing property of solar water heater be significantly improved.Owing to be provided with drainage tube, utilize the atmospheric pressure difference can make delivery port pressure become bigger; When last water, can wash away, can effectively prevent the generation of incrustation scale, and greatly reduce the bombing probability the vacuum tube inwall.The end mouth of pipe that the drainage arm is positioned at the vacuum tube bottom is the opening of cutting sth. askew, and the diagonal cut joint design has increased orifice area, can effectively alleviate obstruction.

The specific embodiment
Shown in accompanying drawing 1,2.
Solar vacuum-tube water heater, comprise heat storage water tank 1 and vacuum tube 2, heat storage water tank 1 is provided with water inlet pipe and water outlet pipe 5, side overflow pipe 3 and upper air-vent 4, in heat storage water tank 1, be provided with drainage and be responsible for 6, be provided with drainage arm 7 in every vacuum tube, drainage be responsible for 6 with drainage arm 7 between be connected by two-tube seal nipple 9, the drainage person in charge 6 directly is connected with water inlet pipe and water outlet pipe 5.Between the bottom of the mouth of pipe of every vacuum tube 2 and heat storage water tank 1, be provided with secondary drainage tube arm 8.
During use water nozzle is arranged on and is lower than complete machine lowest water level place, just can by drainage be responsible for 6 and drainage arm 7 water in heat storage water tank 1 and the vacuum tube 2 are all drawn.When water level in the heat storage water tank 1 was higher than vacuum tube 2 mouths of pipe, hot water flowed into drainage arm 7 by vacuum tube 2 earlier, entered the intake-outlet that 6 arrival water inlet pipe and water outlet pipes 5 are responsible in drainage by drainage arm 7 again; When water level in the heat storage water tank 1 was lower than vacuum tube 2 mouths of pipe, the water in the heat storage water tank 1 flowed into vacuum tube 2 by secondary drainage arm 8, enters the intake-outlet that 6 arrival water inlet pipe and water outlet pipes 5 are responsible in drainage through drainage arm 7 again; After treating that the whole drainages of hot water finish in the heat storage water tank 1, the hot water in the vacuum tube 2 is all drawn through the drainage person in charge 6 and drainage arm 7 again.
