Summary of the invention
The technical problem to be solved in the present invention is that existing hydrocone type solar water heater is unfavorable for making, packs and transportation; Water that can not the extinction water tank bottom; Gas in the siphoning installation can't be arranged light, thereby affects normal siphon; During the interior anhydrous air drying of vacuum tube, the easy bombing of upper water.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of hydrocone type solar water heater, comprise water tank, vacuum tube and siphoning installation, water tank is comprised of inner bag and shell, be provided with heat-insulation layer between inner bag and shell, described siphoning installation comprises a pipe connected pipe, front arm, siphon house steward and rear arm; Front arm one end links to each other with the siphon house steward, and the other end stretches in the vacuum tube; Prop up pipe connected pipe one end and front arm mouth of pipe place and be tightly connected, the other end extend into the vacuum tube bottom; Front arm, pipe connected pipe equal in number in the number of vacuum tube; Rear arm one end siphon house steward links to each other, and the other end stretches to water tank bottom, and rear arm quantity is at least one.
It is as a whole that existing hydrocone type solar water heater stretches into siphoning installation and the water tank of vacuum tube, because that siphoning installation stretches out water tank is very long, is unfavorable for very much packing and transportation.The siphoning installation that the present invention will stretch into vacuum tube is divided into front arm and pipe connected pipe two parts, can with these two parts to on-the-spot installation combination, be convenient to make packing and transportation; The vacuum tube that the front arm mouth of pipe is arranged on the tank shell is installed the place, aperture, also is convenient to front arm and installs with a pipe connected pipe is on-the-spot.In addition, existing hydrocone type solar water heater is only considered the water in the extinction vacuum tube, and does not consider the water of extinction water tank bottom; And the water of water tank bottom is usually less than the vacuum tube oral area, can't be by the water extinction of vacuum tube with this part, therefore set up rear arm, and the water that the quantity of rear arm and bore depend on the water guaranteed in the vacuum tube and water tank bottom is extinction simultaneously, owing to can guarantee the water while extinction of water and water tank bottom in the vacuum tube, thereby greatly improve the daily useful energy of water heater.
Be to guarantee normally siphon of the present invention, the siphon house steward is positioned at the bottom of inner water tank, and intersects vertically with the extended line of vacuum tube axis; Two end caps of siphon house steward and inner water tank are fixedly connected with, and siphon house steward's a end is positioned at heat-insulation layer, and reaches water tank upper, and communicates with inner bag at water tank upper, and its other end links to each other with water inlet pipe and water outlet pipe; That section body that the siphon house steward reaches water tank upper is provided with check valve.Existing hydrocone type solar water heater is not considered the problem of the air in the emptying siphoning installation how, in case air is arranged in the siphoning installation, just can't guarantee normal siphon.The present invention is by installing check valve, and when water inlet, the air in the siphoning installation is emptying by check valve, without air, guarantees the normal operation of siphon function in guaranteeing to manage; Check valve autoshutdown when water, but siphon water.In addition, the setting of siphon house steward position is conducive to guarantee its Rigidity and strength, thereby guarantees to install the reliability when propping up pipe connected pipe.
Upper water bombing when preventing in the vacuum tube anhydrous air drying; The present invention also is provided with automatic upbound controller, and its input is connected with two water temperatures, level sensor, and its output connects entering water electromagnetic valve; One in aforementioned two water temperatures, the level sensor extend in the vacuum tube, and another is arranged in inner water tank.Described automatic upbound controller is prior art, and when automatic feeding water during temperature≤50 ℃ in anhydrous in the vacuum tube and the pipe, guaranteeing not can bombing; When in the vacuum tube water being arranged, timing water-feeding reached designated water level and automatically stopped upper water 8 o'clock mornings, and so guaranteeing can bombing yet.
Advantage of the present invention is: be convenient to make, install and transportation; The daily useful energy of water heater is high; Can arrange the gas in the light siphoning installation, reliability is high; The situation of upper water bombing in the time of can not air drying occurring.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Shown in Fig. 1-2, siphoning installation comprises front arm 8, siphon house steward 3 and the rear arm 5 that is connected as a single entity; Front arm 8 stretches in the vacuum tube 1, the mouth of pipe of front arm 8 is positioned at vacuum tube installing hole 9 places of tank shell, a pipe connected pipe 2 also is installed on the front arm 8, propping up pipe connected pipe 2 is stainless steel tube, propping up pipe connected pipe 2 adopts thread seal to be connected with front arm 8 mouth of pipe places, pipe connected pipe 2 extend into the bottom of vacuum tube, and the quantity of front arm 8 equals the number of vacuum tube 1; Rear arm 5 stretches to water tank bottom.During use, by quantity and the bore of adjusting rear arm 5, guarantee that the water while extinction of water and water tank bottom in the vacuum tube 1 gets final product.Siphon house steward 3 two ends are welded on two end caps of inner water tank, and an end links to each other with water inlet pipe and water outlet pipe 7, and the other end is positioned at heat-insulation layer and extends water tank upper, and check valve 4 is installed.When water inlet, the air in the siphoning installation is emptying by check valve 4, in guaranteeing to manage without air, check valve 4 autoshutdowns when water, but siphon water.
The present invention also is provided with automatic upbound controller 6, and its input is connected with water tank water temperature, level sensor 6-1, also is connected with the water temperature, the level sensor 6-2 that extend into the vacuum tube bottom, and its output connects entering water electromagnetic valve 6-3.Automatic feeding water when temperature≤50 in the interior anhydrous and pipe of vacuum tube 1 ℃; When in the vacuum tube 1 water being arranged, timing water-feeding reached designated water level and automatically stopped upper water 8 o'clock mornings.
