Anti-freezing type water heater

Abstract

The invention discloses an anti-freezing type water heater. The anti-freezing type water heater comprises a water heater body, a water inlet pipe, a water outlet pipe, a blower device and a control system; a heat exchange device is arranged on the water heater body, and a water passing pipeline is arranged on the heat exchange device; the water inlet pipe is mounted on the water heater body, and an outlet of the water inlet pipe communicates with the water passing pipeline; the water outlet pipe is mounted on the water heater body, and an inlet of the water outlet pipe communicates with the water passing pipeline; the blower device communicates with the water inlet pipe or the water outlet pipe or the water passing pipeline and can blow air into the water passing pipeline so as to discharge stored water in the water passing pipeline; and the control system can control starting and stopping of the blower device. When needed, the blower device can be started to blow the high-pressure air into the water passing pipeline of the heat exchange device, the high-pressure air is utilized to discharge the stored water in the water passing pipeline of the heat exchange device, and the phenomenon that the water passing pipeline is expanded to be cracked due to the fact that the stored water in the water passing pipeline is frozen is avoided.

Description

technical field [0001] The invention relates to the field of household bathing equipment, in particular to an antifreeze water heater. Background technique [0002] After the heating source of the water heater is turned off, there will always be water in the water pipe of the water heater. When the ambient temperature is below 0°C, the water in the water pipe will freeze, and the volume of the water will increase after freezing, which may Cause the water pipe of the water heater to burst. Existing water heater antifreeze mainly contains means such as manual drainage and electric heating. The manual drainage solution needs to close the water inlet valve after using the water heater, and open the water outlet valve at the same time to discharge the water in the water pipe. The water stored in the water pipe may not be drained out, and when the user forgets to drain the water, it is likely to cause the water stored in the water pipe to freeze and cause the water pipe to burst...

AI Technical Summary

Problems solved by technology

The manual drainage solution needs to close the water inlet valve after using the water heater, and open the water outlet valve at the same time to discharge the water in the water pipe. The water stored in the water pipe may not be drained out, and when the user forgets to drain the water, it is likely to cause the water stored in the water pipe to freeze and cause the water pipe to burst; the electric heating scheme is generally: set a temperature control on the water pipe switch and an electric heater controlled by a temperature control switch, once the water temperature is lower than the set temperature, the electric heater will start to heat, thereby ensuring that the temperature of the water stored in the water pipe is higher than 0 ℃, this method often requires continuous heating , higher power consumption
