Description

A pressure-free automatic first-out hot water antifreeze water-saving combined solar water heater

(1) Technical field

The utility model relates to a transformation technology of a solar water heater, in particular to a combined solar water heater of a non-pressurized automatic first-out hot water antifreeze and water-saving type.

(2) Background technology

On May 25, 2006, the applicant applied for a utility model patent titled "A Combined Solar Water Heater without Pressure and Automatic Hot Water First Discharge", and its patent application number is 200620084710.8. In the use of this technology Also there are two problems: the one, the water inlet pipe of solar water heater and the water outlet pipe may freeze in winter;

(3) Contents of the invention

The technical task of the utility model is to aim at the deficiencies of the prior art, to provide a kind of antifreeze system in which the water inlet pipe and the water outlet pipe are both in an empty pipe antifreeze state in winter, and the water outlet pipe is discharged first without cold water throughout the year. Water-saving combined solar water heater.

The technical scheme that the utility model solves its technical problem adopts is:

The pressureless automatic first-out hot water antifreeze water-saving combined solar water heater includes a water tank and an attached water tank in the prior art, the water inlet pipe of the water tank is connected with the outlet pipe of the attached water tank, and the water level controller is arranged at the inlet of the attached water tank. On the water pipe, a one-way valve is arranged on the ventilation pipe at the top of the water tank, and a shower nozzle is installed at the lower end of the water outlet pipe of the water tank. The innovation point is that a three-way ball valve is installed at the lower end (in the bathroom) of the water inlet pipe attached to the water tank, and the purpose is to discharge the water in the water inlet pipe to prevent freezing. In the non-freezing season, it is also necessary to install an ordinary valve on the water inlet pipe close to the three-way ball valve, in order to save water during use. The water inlet pipe on the attached water tank and the water outlet pipe on the water tank can be made to be in the antifreeze state of the empty pipe in winter like this, and the water outlet pipe of the water tank does not have cold water to discharge earlier throughout the year, and directly discharges hot water. Above-mentioned three-way ball valve and valve also can be replaced with a water mixing valve with above-mentioned two kinds of functions.

Compared with the prior art, the utility model has the beneficial effect that the water in the two water pipes is flowing when the water in the two water pipes is flowing when bathing in winter. It will not freeze. When not bathing, the water in the water inlet pipe and the water outlet pipe is completely emptied, and the two empty pipes must be antifreeze; and because the water outlet pipe is in an empty state all the year round, hot water can be discharged directly when bathing. The cold water in the pipe that must be discharged from the water outlet pipe is saved.

(5) Specific implementation methods

Below in conjunction with accompanying drawing, a kind of non-pressurized automatic first-out hot water antifreeze water-saving combined solar water heater of the utility model is described in detail below.

As shown in the accompanying drawings, a non-pressurized automatic first-out hot water antifreeze water-saving combined solar water heater of the utility model has a structure including a water tank 5 and an attached water tank 10 in the prior art, and the water tank 5 is provided with a water inlet pipe 6 , water outlet pipe 7 and vent pipe 2, a one-way valve 1 is installed on the vent pipe 2, and the function of the one-way valve 1 is to only allow the air in the water tank 5 to discharge outwards, and does not allow outside air to enter in the water tank 5, and the outlet The water pipe 7 is provided with a shower nozzle 8, the attached water tank 10 is provided with a water inlet pipe 13 and an outlet pipe 12, the outlet pipe 12 is connected with the water inlet pipe 6 on the water tank 5, and the water inlet pipe 13 is provided with a water surface controller 11, a water surface controller 11 Ensure that the position of the water surface position 9 remains unchanged, and the water surface position 9 and the water surface position 3 are on the same horizontal line. The working principle of the through ball valve 14 is that when the AC closes AB, the water inlet pipe 13 normally enters water, and when the AC closes AD, the water in the water inlet pipe 13 will flow out from AB. The reason why the three-way ball valve 14 is installed can make the water inlet pipe 13 of the attached water tank 10 be in an empty pipe state. This is because the prior art is installed on the water inlet pipe 13 of the attached water tank 10 when the water inlet pipe 13 enters the water. The water surface controller 11 will keep the water surface at the water surface position 9. Since the water tank 5 and the attached water tank 10 have been connected, the water surface in the water tank 5 should also be at the water surface position 3 (same as the water surface position 9). Turn on the shower head 8 just can take a bath, but bathing is finished, and the water inlet pipe 13 of attached water tank 10 can't be emptied (no drain outlet), so just can't prevent freezing. After the three-way ball valve 14 is installed, after bathing, the AC of the three-way ball valve 14 is adjusted to the position of AD, and the air enters the water inlet pipe 13 from the water inlet of the water surface controller 11 installed on the water inlet pipe 13 of the attached water tank. The water in the water inlet pipe 13 will flow out from AB very quickly, so the water inlet pipe 13 is empty; after the AC of the three-way ball valve 14 is closed to AD, open the shower nozzle 8 installed on the outlet pipe 7 of the water tank, and the outlet pipe The water in 7 will flow out from the shower nozzle 8, but because the one-way valve 1 that is installed on the vent pipe 2 is closed to prevent air from entering, a negative pressure is formed in the water tank 5, and the water in the attached water tank 10 will flow into the water tank 5 at this moment. In the water tank 5, as the water level in the attached water tank 10 and its outlet pipe 12 decreases, the air will enter the water tank 5 from the attached water tank 10, and then enter into the outlet pipe 7 through the water outlet 4 in the water tank 5, and the outlet pipe The water in 7 will be discharged from shower nozzle 8, and outlet pipe 7 is also just empty pipe like this. The water inlet pipe 13 and the water outlet pipe 7 have all become empty pipes and have just reached the purpose of antifreezing.

Water saving refers to water use in spring, summer and autumn, because in the non-freezing season, the water inlet pipe 13 must be in a state of full water. Using the three-way ball valve 14 again, the valve 15 is used. When the valve 15 is opened for water intake, the water surface controller 11 makes the water surface of the attached water tank 10 and the water tank 5 reach the positions of the water surface position 9 and the water surface position 3 quickly, and the shower nozzle 8 can be opened to take a bath. Before the bath is finished, the valve 15 is closed in advance, Allow the remaining water in the water tank 5 to be washed and the bathing is over. The outlet pipe 7 is in an empty state all the year round, and the shower nozzle 8 is in an open state all the year round. As long as you take a bath, the outlet pipe 7 will discharge hot water earlier. Take a bath next time, open the valve 15 again, and repeat the previous bathing process. Throughout the three seasons of spring, summer and autumn, only need to open and close the valve 15 has just completed the whole process of bathing, without any cold water discharge, would it not save water?

It should be noted that in areas without freezing throughout the year, it is not necessary to install the three-way ball valve 14 on the water inlet pipe 13 of the attached water tank 10, and only the valve 15 can be installed to realize water saving throughout the year.

A non-pressurized automatic first-out hot water antifreeze water-saving combined solar water heater of the utility model is simple and convenient to manufacture, and can be processed and manufactured as shown in the accompanying drawings.

Except for the technical features described in the instructions, all are known technologies by those skilled in the art.
