Gas water heater water inlet joint equipment and water heater including the same

Abstract

The invention discloses a water inlet joint device for a gas water heater and a water heater containing the water heater. The water inlet joint device for a gas water heater includes a valve body, a boss assembly, a sealing rod assembly, a support assembly, a limit assembly, a drive assembly and a heating assembly. The valve body includes a water inlet, a water outlet and a water flow channel. The boss component is located in the water flow channel, and the sealing rod component can move in the valve body. The sealing rod component blocks or conducts the water flow channel by abutting against or away from the boss component; the support The component assembly applies a force to the sealing rod assembly to make the sealing rod assembly close to the boss assembly; the limit assembly restricts the movement of the sealing rod assembly; the drive assembly drives the limit assembly to move to achieve the limit assembly from the sealing rod assembly, and the heating assembly is used for heating valve body. When the ambient temperature is low and the water heater is powered off, the sealing rod assembly moves to close the water flow channel, so as to avoid freezing of water in the water heater and cracking of the whole water heater when the water heater is powered off and the water inlet valve is not cut off at low temperature.

Description

technical field [0001] The invention relates to a gas water heater water inlet joint device and a water heater comprising the same. Background technique [0002] China is a vast country, and the temperature in the southern region is above zero degrees Celsius most of the year, and the existing water heaters generally lack antifreeze devices. When the cold air comes, the temperature drops below zero degrees Celsius. If an accident such as a power outage occurs at this time, because the water inlet valve of the water heater is not closed in time, water with a lower temperature enters the water heater. However, in the case of a power failure, the water in the water heater cannot be After being heated, as the temperature drops, the water in the water heater is easy to freeze, which will cause the whole machine to freeze and crack, and the whole water heater leaks, causing the floor to soak in water, electrical leakage and other property losses and even personal safety problems. ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a gas water heater water inlet joint device and a water heater containing it in order to overcome the defects of the existing technology that the water heater is powered off and the water is not interrupted when the water heater is cut off.
