The solar water heater with high volume ratio can take full use of the hot water in the heat collection pipe, in other words, the volume of the water tank is increased. Under the condition of the same water consumption, the size of the water tank can be reduced, so as to facilitate the fabrication and the installation of wall-mounted solar water heaters.
Description
Technical field
The utility model relates to a kind of solar water heater, is a kind of big plot ratio solar water heater specifically.
Background technology
Prior solar water heater is made of water tank and thermal-collecting tube, and water tank is positioned at the upper end of thermal-collecting tube; Thermal-collecting tube is used to absorb solar energy water is heated, and water tank is used for stored hot water.Because what thermal-collecting tube adopted is glass material, so annex such as water inlet pipe and water outlet pipe can only be installed on the water tank.Like this, the water that people use can only be the water in the water tank, and the water in the thermal-collecting tube can't utilize.With 2.8 liters of calculating of every thermal-collecting tube volume, the hot water that the solar water heater of 20 arms only can't be discharged in the thermal-collecting tube just reaches 56 liters, and enough 2 people have a bath used.Especially for wall-hanging solar water heater,, require the volume of water tank can not be too big for the ease of installing.Therefore, how to utilize limited water tank volume to realize that big as far as possible rate of thermal water utilization becomes the difficult problem that modern wall-hanging solar faces.
Summary of the invention
The purpose of this utility model provides a kind of big plot ratio solar water heater simple in structure, can make full use of the hot water in water tank and the thermal-collecting tube, obtains more used hot water with less water tank volume.
The utility model is that the technical scheme that the technical solution problem is adopted is:
Big plot ratio solar water heater described in the utility model comprises water tank, is inserted into the thermal-collecting tube on the water tank, the thermal-collecting tube upper open end is communicated with the inner chamber of water tank, water tank is provided with water inlet pipe, it is characterized in that: be connected with extension on the mouth of pipe that is positioned at water tank inside of described water inlet pipe, the upper end of described extension is communicated with water inlet pipe, extension is inserted in the thermal-collecting tube, and the lower end of extension extends to the bottom of thermal-collecting tube.
The joining place of described extension and water inlet pipe has the unhurried current piece.
Described water tank is horizontally disposed with, and thermal-collecting tube is inserted into the bottom of water tank, also is provided with outlet pipe, evacuated tube on the water tank.
Described water tank vertically is provided with, and thermal-collecting tube is inserted into the side of water tank, is provided with outlet pipe in the upper end of water tank, is provided with return pipe in the lower end of water tank, is connected with triple valve between outlet pipe and return pipe.
Owing to adopted said structure, this big plot ratio solar water heater can be equivalent to strengthen the volume of water tank with the hot water that makes full use of in the thermal-collecting tube.Under the situation of identical water consumption, can adopt less water tank, be convenient to make and install wall-hanging solar water heater.

Fig. 2 is the cutaway view of another embodiment of the utility model.
Fig. 3 is the cutaway view of another embodiment of the utility model.
The specific embodiment
As shown in Figure 1, big plot ratio solar water heater described in the utility model comprises water tank 1, is inserted into the thermal-collecting tube 2 on the water tank 1, and thermal-collecting tube 2 upper open ends are communicated with the inner chamber of water tank 1, and water tank 1 is provided with water inlet pipe 3, evacuated tube 5 and outlet pipe 4.Described water tank 1 is horizontally disposed with, and thermal-collecting tube 2 is inserted into the bottom of water tank 1.Be connected with extension 6 on the mouth of pipe that is positioned at water tank 1 inside of described water inlet pipe 3, the upper end of described extension 6 is communicated with water inlet pipe 3, and extension 6 is inserted in the thermal-collecting tube 2, and the lower end of extension 6 extends to the bottom of thermal-collecting tube 2.
In addition, described extension 6 has unhurried current piece 7 with the joining place of water inlet pipe 3.The effect that unhurried current piece 7 is set is the speed that can change current.In order to make the speed of intaking in each thermal-collecting tube about the same, near unhurried current piece 7 is set in the extension 6 of water inlet pipe 3 water inlet ends, can suitably reduce the speed of current, make the thermal-collecting tube water intake velocity of itself and far-end close.
What the foregoing description adopted is the technical scheme that water inlet pipe separates with outlet pipe.During water, by water inlet pipe 3 water inlet, cold water is delivered to the bottom of each thermal-collecting tube by water inlet pipe 3 and extension 6, and hot water is ejected, and overflows from outlet pipe 4.
Present embodiment also can be used for water inlet pipe and outlet pipe is the situation of same water pipe.At this moment, cancellation outlet pipe 4, Draw off valve is installed in position lower on water inlet pipe 3.In the time of water, close water intaking valve on the water inlet pipe 3, open the Draw off valve on the water inlet pipe 3, under siphonage, hot water is by from thermal-collecting tube bottom inspiration extension 6, and discharges by water inlet pipe 3.
When as shown in Figure 2, being used for wall-hanging solar water heater.Can adopt the form of horizontal thermal-collecting tube.Described water tank 1 vertically is provided with, and thermal-collecting tube 2 is inserted into the side of water tank 1, is provided with outlet pipe 4 in the upper end of water tank 1, is provided with return pipe 8 in the lower end of water tank 1, is connected with triple valve 9 between outlet pipe 4 and return pipe 8, installs on triple valve 9 and uses penstock.The effect of triple valve 9 is communicated with on the one hand or closes water route between outlet pipe 4 and the return pipe 8, opens or close the water route with penstock on the other hand; The structure of this triple valve 9 can have a variety of, is known technology, no longer repeats at this.Other part-structures of present embodiment are with embodiment 1.
During use, when triple valve 9 is in closed condition, by triple valve 9 outlet pipe 4 is communicated with return pipe 8, outlet pipe 4, return pipe 8, water tank 1 form a circulation waterway at this moment, heated hot water rises in the thermal-collecting tube 2, get back in the water tank 1 by outlet pipe 4, triple valve 9, return pipe 8, water constantly is heated in the process of circulation.When needing water, open triple valve 9, the water route between outlet pipe 4 and the return pipe 8 is closed, open outlet pipe 4 simultaneously and with the water route between the penstock.Under the tap water pressure effect, the hot water in the water tank 1 is by outlet pipe 4, triple valve 9, trickle out with penstock.Meanwhile, running water enters the bottom of thermal-collecting tube 2 by water inlet pipe 3, extension 6, is full of thermal-collecting tube 2 gradually and simultaneously hot water is ejected.
In order to improve the efficient of water circulation, as shown in Figure 3, can also on the water route between outlet pipe 4 and the return pipe 8, auxiliary water tank 10 be set, auxiliary water tank 10 is connected with triple valve 9.Auxiliary water tank 10 helps to accelerate the circulation of water, and the heat that thermal-collecting tube 2 is produced is delivered to the water in whole water tanks as far as possible.
