Abstract

The invention relates to a zero cold water device of a water heater. The zero cold water device comprises a shell, a constant-temperature bin and a circulating water pump are installed in the shell, the upper end of the constant-temperature bin is connected with a water outlet of the water heater, and the lower end of the constant-temperature bin is connected with a water outlet connector through a hot water outlet pipe; and the circulating water pump is connected with a water inlet connector of the water heater through a water inlet pipe, the lower end of the circulating water pump is connected with a three-way ball valve through a water pump connecting pipe, the three-way ball valve is connected with a water way stop valve, the water way stop valve is connected with a water inlet, a temperature sensor is installed at the water inlet connector of the water heater, and a controller is further arranged in the shell. The zero cold water device is provided with the stop valve, water flow is automatically controlled to be opened and closed, and the product structure is generally applied to motor homes and household water heaters which are systematically compatible.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a zero-cooling water device for the water heater. Background technique [0002] Now in the daily use of the water heater, some cold water will inevitably flow out when the water comes out, and these cold water will generally be let off, and normal use will not start until the hot water flows out. Especially when it is used in winter, the water in the whole hot water system pipe is cold, and the water in the water pipe may freeze and affect the normal use of the water heater. [0003] In addition, due to the use environment, tap water or outdoor water sources that are usually used, due to the difference in water quality, scale deposits will occur on the inner wall of the water pipe of the gas water heater. When the water temperature exceeds 60°C, the scale deposition speed is accelerated. Over time, the scale will accumulate more and more. When people drink water containing scale, ...
