Abstract

The utility model relates to a siphon antifreezing solar water heater, which belongs to the field of heating liquid, particularly the water heater. The siphon antifreezing solar water heater comprises a water tank, a heat preservation layer, and a water pipe. The utility model is characterized in that a siphon pipe is communicated on the side surface of the water tank by utilizing a siphoning principle. Thus, residual water in the water pipe can be timely emptied. Freezing and block in winter can be effectively prevented.

Description

The siphon anti-freezing solar water heater

The utility model relates to a kind of siphon anti-freezing solar water heater, belongs to liquid heating field, particularly water heater.

At present; continuous enhancing along with people's environmental consciousness; every field in life, work; all seeking pollution-free, energy-conservation, measure efficiently; and the utilization of solar energy is a green revolution on the human energy history; particularly solar water heater is low because of its use cost; the environmental protection degree is high and more and more be subjected to people's attention; the scope of application is also more and more wider; but; solar water heater uses the easy outlet pipe that takes place to freeze stifled phenomenon in the winter of cold, and people attempt to solve, and for example adopt thermal insulation coatings, electrical heating protection etc.

The purpose of this utility model is for people provide a kind of siphon principle that utilizes, and solves the siphon anti-freezing solar water heater of above-mentioned water heater drawback.

The purpose of this utility model realizes by following mode: feed a siphon pipe to water tank bottom in the side of water-heater water tank, siphonal other end bifurcated outside water tank is evacuated tube and upper hose, be connected to an exhaust-valve on the evacuated tube, and the upper hose other end joins with an oral siphon and an outlet pipe, on oral siphon, be connected to into water valve, on outlet pipe, be connected to shower nozzle and outlet valve, open water valve filled with water in water tank during use, after the thermal-collecting tube heating, open outlet valve and can obtain hot water, when weather is cold, prevent freezing each several part water pipe, can open exhaust-valve and outlet valve, will the emptying upper hose in residual water.

Description of drawings:

Fig. 1 is overall structure figure of the present utility model.

Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated:

Shown in Fig. 1 a kind of embodiment of the present utility model, it comprises water tank [1], insulation material [2] and water pipe etc., its structural characteristics are: the top of a side [3] of water tank [1] is connected with an overflow pipe [4] and a siphon pipe [5], siphon pipe [5] is passed into the bottom surface of water tank [1], and its other end bifurcated is evacuated tube [6] and upper hose [7], the other end of upper hose [7] communicates with oral siphon [8] and outlet pipe [9] simultaneously, on oral siphon [8], be connected to one and go into water valve [10], on outlet pipe [9], be connected to an outlet valve [11] and shower nozzle [12], and the other end of evacuated tube [6] is connected to an exhaust-valve [13], overflow pipe [4] bifurcated is blast pipe [14] upwards and downward drainpipe [15], blast pipe [14] communicates with atmosphere, drainpipe [15] is received and is prevented the spilling water outflow within doors, also have a leakage fluid dram [6] in water tank [1] bottom, side in addition, valve is housed on it, discharge waste water, dirt etc.

The utility model has the advantage of simple in structurely, use, easy for installation, and good freezing protection effect.

Claims

A kind of siphon anti-freezing solar water heater, comprise water tank and heat-insulation layer, water pipe, the top that it is characterized in that a side of water tank is connected with a siphon pipe and an overflow pipe, siphon pipe is passed into the bottom surface of water tank, and its other end bifurcated is evacuated tube and upper hose, the other end of upper hose communicates with oral siphon and outlet pipe simultaneously, on oral siphon, be connected to one and go into water valve, be connected to an outlet valve and shower nozzle on the outlet pipe, and the other end of evacuated tube is connected to an exhaust-valve, overflow pipe then bifurcated also has a leakage fluid dram in addition for blast pipe upwards and downward drainpipe in the bottom of water tank side.
