Abstract

The invention discloses a water heater capable of preventing dry heating. The water heater comprises a water heater body (1), wherein the upper end of the water heater body (1) is connected with a water storage tank (2). The water heater is characterized in that the outlet end of the water storage tank (2) is connected with the upper end of a water feeding pipe (3); an infrared detector (10) is mounted above the side wall of a heating water cavity (8); the infrared detector (10) is connected with an electromagnetic driver through a cable; and the electromagnetic driver is connected with a driving switch on a right a water feeding valve (5). According to the water heater capable of preventing the dry heating, a low-water-level water replenishing control device consisting of the infrared detector is mounted above the side wall of the heating water cavity, so that a water level in the heating water cavity can be detected, the heating water cavity can be replenished with water in time in case of the low water level, the phenomenon of dry heating is avoided, and the safety is improved.

Description

technical field [0001] The invention relates to a water heater, in particular to a water heater capable of preventing dry heating, and belongs to the technical field of household appliances. Background technique [0002] Most of the existing water heaters have simple structures and single functions. The upper end of the water dispenser is connected with a water storage tank or a pure water inlet pipe. The water level in the heating chamber of the existing water heaters is low, and it is easy to cause damage to the equipment when it is still heating. It is also easy to cause the water to be heated repeatedly, which will adversely affect the water quality. When the water level in the heating chamber is low, it is impossible to replenish water in time, and once the water level sensor fails after being used for a long time, it will also cause low water level heating in the heating chamber. Contents of the invention [0003] The purpose of the present invention is to solve the...
