Description

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

(1) Technical field

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

(2) Background technology

The applicant applied for two utility model patents on May 25, 2006 and December 15, 2006, with the same name as "a solar water heater with no pressure and automatic first-out hot water". The patent application numbers are 200620084711.2 and 200620011955.8, also there are two problems in the use of above-mentioned technology: the one, the water inlet pipe and the outlet pipe of solar water heater 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 solar water heater.

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

The pressure-free automatic first-out hot water antifreeze water-saving solar water heater includes a water tank and a water inlet pipe and an outlet pipe arranged on the water tank. The nozzle and the vent pipe with one-way valve, the water tank is equipped with a partition plate to divide the water tank into the left chamber where the water inlet pipe is located and the right chamber where the water outlet pipe is located. The position is higher than the water outlet of the connecting pipe in the right chamber and lower than the water surface in the water tank. The innovation point is that a three-way ball valve is installed on the water inlet pipe of the water tank to discharge the water in the water inlet pipe to prevent freezing. In non-freezing areas and seasons, it is also necessary to arrange a valve on the water inlet pipe close to the three-way ball valve, so as to save water during use. In this way, the water inlet pipe and the water outlet pipe are in the antifreeze state of the empty pipe in winter, and the water outlet pipe is discharged without cold water 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.

In order to ensure that the water in the water tank is full and prevent the water from flowing back from the water inlet pipe after the water is cut off, causing the vacuum tube to burst, this problem can be solved by moving the original water inlet installed at the bottom of the water tank to the upper part of the side of the water tank.

Compared with the prior art, the utility model has the beneficial effect that the pressureless automatic first-out hot water antifreeze and water-saving solar water heater of the utility model is: the water in the two water pipes is flowing when bathing in winter, and the It will 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 always in the state of empty pipes, hot water can be discharged directly when bathing, saving water. The water pipe must first drain the cold water inside the pipe.

(5) Specific implementation methods

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

As shown in the accompanying drawings, a pressure-free, automatic, anti-freezing and water-saving solar water heater of the utility model has a structure including a water tank 4 of the prior art, an inlet pipe 6 and an outlet pipe 19 arranged thereon, and the water tank 4 The water inlet pipe 6 is provided with a water surface controller 2 and a vent pipe 1, a shower nozzle 20 and a vent pipe 11 with a one-way valve 10 are installed on the outlet pipe 19 of the water tank 4, and an isolation plate 15 is arranged in the water tank 4 to separate the water tank 4. It is divided into the left chamber where the water inlet pipe 6 is located and the right chamber where the water outlet pipe 19 is located. A connecting pipe 5 is arranged between the two chambers. And lower than the water surface position 13 in the water tank 4, and the function of the one-way valve 10 that is installed on the vent pipe 11 is to only allow the air in the right room to discharge outwards, and does not allow outside air to enter the right room. Its innovative point is that a three-way ball valve 8 and a valve 9 are installed at the lower end of the water inlet pipe 6 of the water tank 4 . The working principle of the three-way ball valve 8 is that when the AC closes AB, the water inlet pipe 6 normally enters water, and when the AC closes AD, the water in the water inlet pipe 6 will flow out from AB. Why just install three-way ball valve 8 and just can make water inlet pipe 6 be in empty pipe state? Because prior art is when water inlet pipe 6 enters water, the water surface controller 2 that is installed on the water inlet pipe 6 can make the water surface remain on the position of water surface position 13, open shower nozzle 20 and just can take a bath, but bath finishes, and water inlet pipe 6 Cannot be drained (no drain) and therefore not frostproof. After installing the three-way ball valve 8, adjust the AC of the three-way ball valve 8 to the AD position after bathing. Since the air can enter the water inlet pipe 6 from the ventilation pipe 1, the water in the water inlet pipe 6 will flow from AB. Flow out soon, and the water inlet pipe 6 is just empty pipe; After the AC of the three-way ball valve 8 is closed AD, open the shower nozzle 20 on the outlet pipe 19, the water in the outlet pipe 19 will flow out from the shower nozzle 20, but because it is installed in The one-way valve 10 on the vent pipe 11 is closed to prevent air from entering, causing negative pressure in the right chamber, and because the vent pipe 1 is provided in the left chamber, the water in the upper part of the left chamber flows into the right chamber through the connecting pipe 5, and the air follows As the water level in the connecting pipe 5 decreases, it enters from the left chamber to the right chamber, and then enters the water outlet pipe 19 through the water outlet 14, and the water in the water outlet pipe 19 will also be discharged from the shower nozzle 20, so that the water outlet pipe 19 is also empty. Nevermind. The water inlet pipe 6 and the water outlet pipe 19 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 6 is required to be in a state of full water, as long as the three-way ball valve 8 is in the position where AC is closed and AB, the three seasons of spring, summer and autumn will no longer Using 3-way ball valve 8, use valve 9 instead. When the valve 9 is opened to enter the water, the water surface controller 2 makes the water surface reach the position of the water surface position 13 quickly, and the shower nozzle 20 is opened to take a bath. After taking a bath, the water outlet pipe 19 is in an empty state all the year round, and the shower nozzle 20 is in an open state all the year round. As long as you take a bath, the water outlet pipe 19 will discharge hot water earlier. Take a bath next time, open the valve 9 again, repeat the previous bathing process. Throughout the three seasons of spring, summer and autumn, only need to open and close the valve 9 has just completed the whole process of bathing, without any cold water discharge, saving the cold water discharged earlier. It should be pointed out that in areas without freezing throughout the year, it is not necessary to install the three-way ball valve 8, only the valve 9 is installed.

In addition, in order to ensure that the water in the water tank 4 is full and prevent the water from flowing backward from the water inlet pipe 6 after the water is cut off, causing the vacuum tube to burst, the original water inlet 7 installed at the bottom of the water tank 4 is moved to the upper part 3 of the side of the water tank to solve this problem.

In order to facilitate cleaning in the water tank 4 , a drain valve 18 is provided in the left chamber of the water tank 4 , and a drain valve 17 is provided in the right chamber of the water tank 4 .
