Example Embodiment

[0021] To facilitate those skilled in the art to better understand the essence of the present invention, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, an antifreeze pressurized gas water heater includes: a gas water heater housing 1, a heat exchanger 2 installed in the gas water heater housing 1, a coil 3 wound on the heat exchanger 2, and a coil 3 The connected water inlet pipe 4, the water outlet pipe 5, and the antifreeze heating element 6 arranged on the coil 3; characterized in that a bypass pipe 7, an electric three-way valve 8 and a booster are also provided in the gas water heater housing 1 The bypass pipe 7 connects the water inlet pipe 4 and the water outlet pipe 5 through an electric three-way valve 8, so that the water inlet pipe 4, the coil 3, and the water outlet pipe 5 form a circulation loop. The booster pump 9 is arranged in the circulation On the...

Abstract

The invention discloses an anti-freezing pressurized gas water heater. The anti-freezing pressurized gas water heater comprises a gas water heater shell body, a heat exchanger installed in the gas water heater shell body, a coiled pipe wound on the heat exchanger, a water inlet pipe and a water outlet pipe which are connected with the coiled pipe, and an anti-freezing heating body arranged on the coiled pipe. The anti-freezing pressurized gas water heater is characterized in that a bypass pipe, an electric three-way valve and a booster pump are further arranged in the gas water heater shell body, the water inlet pipe is communicated with the water outlet pipe by the bypass pipe through the electric three-way valve, the water inlet pipe, the coiled pipe and the water outlet pipe form a circulation loop, and the booster pump is arranged on the circulation loop; and a temperature probe is further arranged on the heat exchanger or the coiled pipe, and the anti-freezing heating body, the electric three-way valve, the booster pump and the temperature probe are all connected with a gas water heater main controller. The anti-freezing pressurized gas water heater disclosed by the invention is simple in installation structure; and moreover, water flow is cooperated with the anti-freezing heating body to heat while flowing in a closed-loop pipeline, the water flow is uniformly heated, and double anti-freezing effect is acted, so that the coil pipe of a water-stopping box is effectively prevented from frost cracking.

Description

technical field [0001] The invention relates to the technical field of gas water heaters, in particular to an antifreeze booster gas water heater. Background technique [0002] The temperature in the northern part of my country is low all the year round, and the water tank coil of the gas water heater is often cracked by freezing. Now most water heater manufacturers use antifreeze heating elements to wrap the water tank coil, and use electric heating to prevent freezing. But when the antifreeze heating element fails or when strong cold wind enters the water tank through the smoke pipe, the cooling rate is even faster than the heating rate of the antifreeze heating element, and the residual water in the water tank will freeze and cause the casing to rupture. [0003] In the prior art, there are also gas water heaters that utilize circulation pumps to realize the antifreeze function. The Chinese utility model patent with publication number CN203375718U discloses a kind of pre...
