Abstract

The utility model discloses an anti-freezing device for a solar water heater, which solves the problem that a water tube of the solar water heater can be easily frozen in winter to cause the blocking problem. The utility model has the main structure that a three-way valve is fixed on a water tank of a water heater; one end of the three-way valve is connected with a water pipe 3, one end of the three-way valve is connected with a siphon pipe 1, the third end of the three-way valve 2 is upward connected with an electromagnetic valve 4; the siphon pipe 1 is inserted into the inner bottom of the water tank 16; the part water pipe 3, which is positioned indoors is connected with two three-way valves 12 and 15. The electromagnetic valve 4 is controlled to be opened and closed to drain the surplus water in the water pipe 3 by an indoor control power supply 6, so the anti-freezing purpose is realized. The utility model has the advantages of simple structure, convenient operation and obvious anti-freezing effect.

Description

A kind of defroster of solar water heater

Affiliated technical field

The utility model relates to the defroster of solar water heater, especially a kind of defroster of solar water heater water pipe.

Background technology

Along with growth in the living standard, people begin to pursue high-quality life, and the popularity rate of solar water heater is more and more higher, use also very convenient.But in the winter of cold, outside the water pipe of water heater was exposed to, the water in the water pipe easily build-up ice and stops up water pipe, causes water heater to use.At this situation, there is the people that water heater is improved, take some antifreezing measures.Nowadays the most frequently used antifreezing measures are emptier to water heater to be installed, and promptly are behind the intact water, the surplus water in the water pipe to be drained on to water heater, and are frozen and stop up with effectively anti-antipriming pipe.Usually the mode that adopts has two kinds: a kind of is that a manual exhaust-valve is installed on water pipe; Another kind is that an electromagnetism exhaust-valve is installed on water pipe.By manual or electric control exhaust-valve closure or openness.More than two kinds of exhaust-valves can play certain antifreezing effect really, but because outlet pipe is installed in the bottom of water tank, and exhaust-valve is mounted in the water pipe, service time is of a specified duration, may cause exhaust-valve to be not closed completely and to leak always, causes water pipe to freeze.

The utility model content

The utility model provides a kind of can effectively prevent the defroster that solar water heater freezes.

For reaching above purpose, above solar water heater water tank, fix a threeway on the lateral wall of water tank, one end of threeway connects siphon pipe, siphon pipe inserts the bottom in the water tank, the other end connects water pipe, the 3rd end of threeway upwards, magnetic valve of its terminal connection, magnetic valve is connected with indoor control power supply by lead, roll over downwards along wall with the threeway water pipe connecting, be folded to the user at the user place indoor, a threeway is arranged on indoor water pipe, and its two ends connect water pipe, and the 3rd end vertically downward, its terminal short tube with a band exhaust-valve is connected, other has threeway one end to be connected with water pipe after the last threeway, and the other end is connected with the outlet pipe of band valve, and the 3rd end is connected with the running water pipe of being with valve, fix a water stage measurement instrument at the top of water tank madial wall, it is connected with alarm with indoor power supply by lead.

Adopt the water heater of above structure, because magnetic valve is positioned at the highest point of water pipe, when magnetic valve was opened, under the external atmosphere pressure effect, air entered siphon pipe and water pipe, and the siphon condition does not possess, and siphonage is ended, and the water in the water pipe is in the moment emptying.On to water-heater water tank, during water, only need close exhaust-valve, outlet pipe valve and magnetic valve, open the running water pipe valve, can fill the tank with water, after water reaches certain position in the water tank, the water level alarm prompting.And when need are used hot water, only need close exhaust-valve, magnetic valve and outlet pipe valve, open running water valve several seconds, close running water valve immediately, open the outlet pipe valve, at this moment the pipe-line system siphon conditions being possessed of water heater, utilize siphonage that the hot water in the water tank " suction " is gone out, for using, operation is very easy, and also the water that never has in the solar water heater water tank spills.Therefore,, do not have surplus water in the water pipe, can prevent that effectively antipriming pipe is frozen except that to water on the water heater and the use hot water.

Further describe the utility model defroster below in conjunction with drawings and Examples
