Gas water heater capable of detecting CO concentration

Abstract

The invention discloses a gas water heater capable of detecting CO concentration. The gas water heater comprises a water heater body, wherein a water heater control panel as well as a CO concentration displayer and a buzzer which are related to safety is mounted on the outer surface of a casing of the water heater body, a gas combustion chamber is arranged in a lower-half space inside the water heater body, a hot water pipeline winds around the outer part of the gas combustion chamber, a vent hole is formed in the top of the gas combustion chamber, and a CO detection device mounted inside the water heater casing is arranged in an upper space inside the water heater body; air inside the water heater casing communicates with the outside via a ventilation window on the casing, and the CO detection device is connected with external equipment via circuit access holes in the CO detection device. The gas water heater can detect the CO concentration in real time during usage and can send out an alarm signal and immediately turn off a working power supply of the gas water heater when the CO concentration exceeds allowable concentration, so that life safety of users is guaranteed. Besides, the gas water heater is simple in structure, small in size and reliable in function.

Description

technical field [0001] The invention relates to the technical field of gas water heaters, in particular to a gas water heater capable of detecting the concentration of carbon monoxide. Background technique [0002] In people's family life, the supply demand for hot water is huge. At present, most urban households are equipped with gas water heaters, which heat tap water by burning natural gas. [0003] The main component of natural gas is methane, which is colorless, odorless, and non-toxic. When it is fully burned, the carbon dioxide and water vapor produced will not harm the human body. However, when methane is not fully combusted, carbon monoxide gas is produced. [0004] On the one hand, the main hazard of carbon monoxide is to combine with hemoglobin in the human body, so that it can no longer combine with oxygen and poison people, which can lead to coma or even death in severe cases; Collision with certain objects and explosion causing casualties and property damage...

However, when methane is not fully combusted, carbon monoxide gas is produced

[0004] On the one hand, the main hazard of carbon monoxide is to combine with hemoglobin in the human body, so that it can no longer combine with oxygen and poison people, which can lead to coma or even death in severe cases; Collision with certain objects and explosion causing casualties and property damage

[0005] Since gas water heaters are mostly installed in places that are not easy to ventilate, such as kitchens or bathrooms, once the oxygen concentration drops, it is easy to cause incomplete combustion of methane, which undoubtedly brings certain safety hazards to the use of gas water heaters.

[0006] At present, there are some instruments for detecting carbon monoxide concentration on the market. Due to the limitations of their quality, volume and ease of use, they are generally widely used in places such as mines and automobiles to detect air safety and quality, and are rarely used in family life.

In addition, because the gas water heater may only produce carbon monoxide gas when it is in use, if the separate detection instrument is always on, it will cause aging and unnecessary waste of the instrument. If it is constantly turned on and off manually, it is not only cumbersome, but also may be forgotten, which is very inhumane
