Solar water heaters convert solar energy into heat energy, thereby heating water in the water tank. The specific gravity of hot water is smaller than that of cold water, so that hot water is above and cold water is below in the water tank. Based on this, if the installation position of the water outlet pipe is high, although the upper layer hot water can be guaranteed to flow out, when the water consumption is large, the water cannot flow out if the water level falls below the water outlet pipe, and the cold water needs to be timely supplemented to maintain a certain water level. Long-term high water level operation affects overall water temperature rise. If the installation position of the water outlet pipe is lower, when the water level in the water tank is higher, the position of the water outlet is positioned in the middle, warm water positioned in the middle is discharged first, and under the condition of less water consumption, the hot water positioned at the uppermost layer cannot be discharged preferentially, so that the utilization rate of the hot water is low. Therefore, there is a need to develop a vacuum tube solar water heater which is flexible in use and can simultaneously consider different use situations of large water consumption and small water consumption.

Detailed Description
The following describes the embodiments of the present utility model further with reference to the drawings. The description of these embodiments is provided to assist understanding of the present utility model, but is not intended to limit the present utility model. In addition, the technical features of the embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.
Example 1
A vacuum tube solar water heater, as shown in figures 1-3, comprises a water tank, a water inlet tube 3 and a water outlet tube 2; a plurality of heat insulation baffles 1 are fixedly arranged in the inner cavity of the water tank to divide the water tank into a plurality of chambers; the upper part of each heat insulation partition board 1 is provided with an upper communicating pipe 6 in a penetrating way; the upper communicating pipes 6 are provided with first electromagnetic valves 7; the water outlet pipe 2 is arranged in the middle of one end of the water tank; the water inlet pipe 3 is mounted at a lower part of one end facing away from the water outlet pipe 2.
According to the vacuum tube solar water heater, the water tank is divided into the plurality of chambers by the heat insulation partition board 1, so that the water storage quantity in the chambers can be controlled to gradually decrease from the position close to the water inlet 3 to the position far from the water inlet 3. The water outlet pipe 2 is arranged in the middle of one end far away from the water inlet pipe 3, so that the water storage quantity in a cavity close to the water outlet pipe 2 is relatively small, and the water level is relatively low. Therefore, when water is used, even if the water consumption is small, the hot water on the upper layer can flow out at first, so that the utilization rate of the hot water is ensured. When the water consumption is large and the hot water in the cavity close to the water outlet pipe 2 is not enough, the first electromagnetic valve 7 on the upper communicating pipe 6 can be controlled to be opened in sequence. Under the action of the water head difference, hot water at the upper part in the adjacent cavity can flow into the upper communicating pipe 6 to supplement, thereby meeting the use requirement. The utility model has simple structure and flexible use, and can simultaneously consider different use scenes of large water consumption and small water consumption.
Specifically, in order to adapt to different water levels in the respective chambers, the installation height of the upper communication pipe 6 gradually decreases from the water inlet pipe 3 to the water outlet pipe 2. The water level of the chamber close to the water inlet pipe 3 is high, the height of the upper communicating pipe 6 is relatively high, the water level of the chamber far away from the water inlet pipe 3 is low, and the height of the upper communicating pipe 6 is relatively low.
Specifically, one end of each upper communicating pipe 6, which is away from the water outlet pipe 2, is communicated with a hose 8; one end of the hose 8 is provided with a floating ball 9. The hose 8 can always float at a position close to the water surface under the action of the floating ball 9, so that the water passing through the upper communicating pipe 6 is ensured to be hot water at the upper layer.
Specifically, one end of the upper communicating pipe 6 close to the water outlet pipe 2 is communicated with a bent pipe 10; the outer diameter of the bent pipe 10 is smaller than the inner diameter of the water outlet pipe 2, and one end of the bent pipe 10 extends into the pipe orifice of the water outlet pipe 2. The hot water introduced from the adjacent chamber can be quickly discharged through the water outlet pipe 2, preventing the introduced hot water from being mixed with the cold water in the chamber.
Specifically, a temperature sensor 14 is installed on the inner wall of the water tank at a position close to the water outlet pipe 2; an electric heater 12 is arranged in the chamber close to the water outlet pipe 2. When the use requirement cannot be met due to the fact that hot water cannot be introduced from other chambers due to water level reasons or weather reasons, the electric heater 12 can be started to independently heat the water in the chamber communicated with the water outlet pipe 2, and the energy consumption can be reduced while the use requirement is met.
Specifically, a vent pipe 4 is arranged at the position of the heat insulation baffle plate 1 close to the top of the water tank in a penetrating way; one end of the water tank is communicated with an exhaust pipe 13. When the temperature of the water in the water tank increases, part of the water may be gasified, resulting in an increase in the pressure in the water tank. The generated gas can flow in each chamber 5 through the through holes 12 and finally be discharged through the exhaust pipe 13 to prevent the deformation of the water tank.
Specifically, the breather pipe 4 is provided with a second electromagnetic valve 11; an air pressure sensor 15 is mounted on the inner top wall of each chamber of the water tank. When the air pressure in the cavity reaches a certain value, the second electromagnetic valve 11 can be controlled to be opened, and the air is discharged through the one-way valve 10 to be decompressed. Before the air pressure reaches a certain value, the second electromagnetic valve 11 is kept closed, so that heat dissipation can be reduced.
Specifically, the exhaust pipe 13 includes an inner pipe 1301; a dust cap 1302 is mounted on top of the inner tube 1301; a plurality of ventilation holes 1305 are formed in the periphery of one end, close to the dust cap 1302, of the inner tube 1301. The dust cap 1302 can prevent foreign materials such as dust from entering the water tank through the exhaust pipe 13.
Specifically, a sliding plate 1303 is slidably mounted in the inner cavity of inner tube 1301; the upper end of the sliding plate 1303 is fixedly connected with one end of a spring 1304; the other end of the spring 1304 is fixedly connected with the lower end of the dust cap 1302. When the air pressure is insufficient to compress spring 1304 before the air pressure reaches a certain level, slide 1303 is in the position shown, and slide 1303 acts to prevent dust from entering and heat from escaping. When the air pressure is gradually increased, the sliding plate 1303 is pushed to move upwards, and the spring 1304 is compressed, so that the inner tube 1201 is communicated with the outside through the air holes 1305 for pressure relief. When the air pressure is reduced, the spring is gradually stretched, the pressure release is finished, and the sliding plate 1303 is plugged again.
Specifically, to prevent heat from being dissipated through the exhaust pipe 13, the inner pipe 1301 is sleeved with an outer pipe 1307; a thermal insulation layer 1306 is filled between the inner tube 1301 and the outer tube 1307.
Example 2
As shown in fig. 4, in the vacuum tube solar water heater, a communicating tube 5 is added only to the lower portion of the heat insulating partition plate 1, compared with the embodiment 1. Specifically, the lower part of the heat insulation partition board 1 is provided with a lower communicating pipe 5 in a penetrating way; the lower communication pipes 5 are each provided with a first electromagnetic valve 7. The rest of the structure is the same as in embodiment 1. The lower communicating pipe 5 is convenient for filling water into each cavity of the water tank, and can also facilitate the flow of cold water at the lower layer in each cavity in the using process.
Working principle of example 1:
for ease of description, the chambers are numbered from left to right: (1) a chamber, (2) a chamber, and (3) a chamber. When the water tank is filled with water, all the first electromagnetic valves 7 are kept open, the water firstly enters the cavity (1), and when the water level in the cavity (1) rises to the height of the upper communicating pipe 6, the water enters the cavity (2) through the upper communicating pipe 6. When the water level in the chamber (2) rises to the height of the upper communication pipe 6, water enters the chamber (3) through the upper communication pipe 6. When the water level in the cavity (3) is higher than the height of the water outlet pipe 2 by a certain distance, the first electromagnetic valve 7 at the rightmost side is controlled to be closed, water injection into the cavity (3) is stopped, and water injection into the cavity (1) and the cavity (2) is continued. And (3) stopping water injection when the water levels in the chamber (2) and the chamber (1) reach the preset height. The water levels of the chamber (1) and the chamber (2) can be identical, and the water level of the chamber (1) can be higher than the water level of the chamber (2).
When the water consumption is small, the hot water in the cavity (3) is discharged first, so that the hot water in the cavity (3) is fully utilized. When the water consumption is large and the hot water in the cavity (3) can not meet the requirement, the first electromagnetic valve 7 on the upper communicating pipe 6 at the rightmost side is controlled to be opened, and the upper layer hot water in the cavity (2) flows into the cavity (3) through the hose 8 and the upper communicating pipe 6 as the water level in the cavity (2) is higher than that in the cavity (3) and is rapidly discharged through the water outlet pipe 2. When the hot water is still insufficient, the adjacent first electromagnetic valve 7 is controlled to be opened, and the hot water in the cavity (1) flows into the cavity (2) and then flows into the cavity (3) under the action of the water level difference, so that the requirement is met.
When the water level difference is eliminated due to insufficient water quantity, hot water in the chamber (1), the chamber (2) cannot be introduced into the chamber (3), or water temperatures in the chamber (1), the chamber (2) and the chamber (3) cannot meet requirements due to weather reasons, the electric heater 12 can be started to independently heat the water in the chamber (3), and the energy consumption can be reduced while the use requirements are met.
Working principle of example 2:
the lower communication pipe 5 is added as compared to embodiment 1, and the first solenoid valve 7 is installed on the lower communication pipe 5. When the water tank is filled with water, the first electromagnetic valves 7 on all the lower communicating pipes 5 can be kept in an open state, and the water can be conveniently and quickly filled into the cavity. When the water injection into a certain chamber is stopped, the corresponding first solenoid valve 7 may be closed. On the other hand, during use, by opening the first electromagnetic valve 7 on the lower communication pipe 5, the cold water in the two chambers communicated with the lower communication pipe 5 can flow under the drive of the temperature difference or the water level difference, so that more use requirements are met. For example, when the water level in the chamber (2) is low, the hot water position is also relatively low, and when the hot water is lower than the upper communication pipe 6 on the right side of the chamber (2), the hot water cannot flow into the chamber (3) through the upper communication pipe 6 to be replenished. At this time, the first electromagnetic valve 7 on the upper communication pipe 6 in the chamber (1) may be opened so that the hot water in the chamber (1) flows into the chamber (2) to be replenished. As the hot water in the chamber (1) flows out, the water level drops below the upper communication pipe 6, and the replenishment is stopped. At this time, (2) hot water is still present in the chamber, but cannot be supplied to (3) the chamber due to the water level. If water still needs to be used at this time, the first electromagnetic valve 7 on the lower communicating pipe 5 between the chamber (1) and the chamber (2) is opened, and the water in the chamber (1) flows into the chamber (2) under the action of the water level difference, so that the water level in the chamber (2) is increased, and the hot water in the chamber (2) can be fed into the chamber (3), so that the hot water utilization rate can be improved.
The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model, and yet fall within the scope of the utility model.
