Technical Field

[0001] The utility model relates to the technical field of antifreeze for gas water heaters, in particular to a gas water heater with an antifreeze drain valve. Background Art

[0002] A gas water heater, also known as a gas water boiler, is a gas appliance that uses gas as fuel and transfers heat to cold water flowing through a heat exchanger through combustion heating to achieve the purpose of preparing hot water.

[0003] When the existing gas water heater is in use, water is transported into the gas water heater through a water pipe, and then ignited to heat the water. The heated water is transported to the kitchen or bathroom through a water outlet pipe for use.

[0004] Based on the above-mentioned related technologies, the applicant believes that in the winter when the temperature is low, water will always remain in the water inlet and outlet pipes inside the gas water heater, which may freeze at night when the temperature is low, thereby affecting the normal use of the gas water heater. To address the above problem, we have launched a gas water heater with an antifreeze drain valve. Utility Model Content

[0005] The utility model discloses a gas water heater with an antifreeze drain valve, which aims to solve the technical problem that water is always retained in the water inlet pipe and the water outlet pipe inside the gas water heater, which may freeze at night when the temperature is low, thereby affecting the normal use of the gas water heater.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] The evaporation nozzle is fixed on the top of the water heater body, and the evaporation nozzle is fixed on the top of the water heater body, and the evaporation nozzle is fixed on the top of the water heater body.

[0008] In a preferred embodiment, the top of the water heater body is symmetrically fixedly connected to exhaust pipes, the bottoms of the two exhaust pipes extend to the interior of the heating chamber and are fixedly connected to exhaust heads, and the tops of the two exhaust pipes are fixedly connected to delivery pipes.

[0009] In a preferred solution, heat dissipation grooves are equidistantly provided on both sides of the water heater body, and an L-shaped dust shield is fixedly connected to the outer side of the heat dissipation groove.

[0010] In a preferred solution, mounting plates are symmetrically fixedly connected to the back of the water heater body, and both mounting plates are L-shaped.

[0011] In a preferred solution, the interiors of the two mounting plates are symmetrically threaded with bolts.

[0012] In a preferred solution, a controller is fixedly connected to the outside of the water heater body, and the No. 1 solenoid valve and the No. 2 solenoid valve are both electrically connected to the controller.

[0013] The utility model provides a gas water heater with an antifreeze drain valve, which has the following advantages:

[0014] First, the anti-freeze mechanism can drain the moisture inside the water supply pipe and the outlet pipe, avoiding the problem of freezing due to low temperature, ensuring the normal use of the gas water heater. At the same time, it also prevents water from expanding and contracting inside the pipe due to heat and cooling, causing damage to the pipe. The structure is simple and practical.

[0015] Secondly, the heat dissipation groove is used to dissipate heat for the gas water heater, and the L-shaped dust shield is used to effectively prevent external dust from entering the gas water heater. The mounting plate is used to conveniently fix the gas water heater and avoid directly attaching the gas water heater to the wall, thus reserving heat dissipation space. The controller is used to facilitate staff to control the opening and closing of the No. 1 solenoid valve and the No. 2 solenoid valve, making operation easier. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In the above technical solution, considering that there is always water in the water inlet and outlet pipes inside the gas water heater, which may freeze at night when the temperature is low, thus affecting the normal use of the gas water heater, in order to solve this problem, the specific operations are as follows:

[0024] Reference Figure 1 - Figure 4 In a preferred embodiment, the No. 2 water stop valve 505 is opened, and then the No. 2 solenoid valve 508 is opened, and the water inside the outlet pipe 503 enters the inside of the drain pipe 506, and then the No. 1 water stop valve 504 is opened to block the input of external water, and then the No. 1 solenoid valve 507 is opened, and the water inside the water supply pipe 501 enters the inside of the drain pipe 506.
