Abstract
The utility model discloses a water heater protector, which comprises a water heater power supply. The utility model is characterized in that the protector comprises a combustible gas sensor, an electric control valve and a microcontroller, wherein the combustible gas sensor is arranged inside a water heater, the electric control valve and the microcontroller are arranged at a combustible gas inlet part, and the microcontroller can control the electric control valve to be opened and closed according to signals of the combustible gas sensor. The utility model has the advantages of simple structure, safety and reliability.
Description
Technical field
The utility model relates to a kind of protective device of water heater.
Background technology
Along with rapid economy development, people's living standard has also obtained very big improvement, up to the present, all generally uses to the rural area, cities and towns from the big city and to have gone up water heater.Though begin now to have engendered electric heater and solar water heater, what account for principle market and status still is gas heater still, and gas heater is subjected to people's welcome deeply with the price of its Lian Mei and the convenience of use.But unfortunately we can hear that often the case that combustion gas is poisoned takes place people when having a bath; what cause that the water heater of poor quality of the existing use of appearance of this phenomenon causes also has because improper use causes; people the ventilation of not noting the bathroom of using gas heater and environment that gas heater is installed too seals or service time the phenomenon that all might cause combustion gas to be poisoned such as long; another important reasons is that existing gas heater does not have wheel leakage protective and warning device mostly, so we have to that gas heater is had the vigilant of height.
The utility model content
Task of the present utility model provides a kind of protective device that cuts off the water heater of fuel gas inlet when the combustion gas leakage takes place automatically.
The technical solution of the utility model is as follows:
A kind of protective device of water heater; comprise water heater power supply; it is characterized in that: this protective device comprises the combustible gas sensor that is arranged on water heater inside, the electrically-controlled valve that is arranged on the combustion gas inlet place and microcontroller, and microcontroller is according to the opening and closing of the signal controlling electrically-controlled valve of combustible gas sensor.
This protective device also comprises the fuel gas warning lamp that is arranged on the water heater panel, and when combustible gas sensor detected fuel gas, described microprocessor control fuel gas warning lamp flicker was luminous.
Described microcontroller inside is provided with time block, and when the time that water heater uses continuously surpassed the value of setting, microcontroller cut off described electrically-controlled valve automatically.
The setting value of described time block is 25 minutes.
The utility model has the advantages that: simple in structure, easy to operate, the reliability height has improved the safety coefficient that water heater uses.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail,
Fig. 1 is the structural principle schematic diagram of the protective device of a kind of water heater of the utility model;
Fig. 2 is the protective device structural representation of a kind of water heater of the utility model.
The specific embodiment
A kind of protective device of water heater; as shown in Figure 1, 2; comprise water heater power supply 5, be arranged on the combustible gas sensor 3 of water heater inside, the electrically-controlled valve 1 that is arranged on the combustion gas inlet place and microcontroller 4, microcontroller 4 is according to the opening and closing of the signal controlling electrically-controlled valve 1 of combustible gas sensor 3.
When combustible gas sensor 3 detected fuel gas, microcontroller 4 control electrically-controlled valve 1 were closed, and cut off the source of burning gases, water heater is in extinguishes state.This protective device can prevent that the user from causing gassed phenomenon because of water heater generation gas leakage.Therefore on water heater, install the safety coefficient that this protective device can strengthen water heater greatly additional.
This protective device also comprises the fuel gas warning lamp 2 that is arranged on the water heater panel, and when combustible gas sensor 3 detected fuel gas, 2 flickers of described microcontroller 4 control fuel gas warning lamps were luminous.This fuel gas warning lamp 2 can allow the user can in time carry out the precautionary measures in time to the current situation of user feedback.
In order to prevent that the user from causing gassed situation after using water heater for a long time, added time block in this protective device.Particularly when the user be in alone use water heater and without any the guardian time, add the becoming more important property of this time block.
The setting value of time block can be made as 25 minutes.After timing arrived, microcontroller 4 control electrically-controlled valve 1 were in closed condition, and this has, and electrically-controlled valve 1 just can be opened when opening water heater once more, and time block is then retimed.
Claims (4)
1. the protective device of a water heater; comprise water heater power supply; it is characterized in that: this protective device comprises the combustible gas sensor that is arranged on water heater inside, the electrically-controlled valve that is arranged on the combustion gas inlet place and microcontroller, and microcontroller is according to the opening and closing of the signal controlling electrically-controlled valve of combustible gas sensor.
2. water heater protective device according to claim 1; it is characterized in that: this protective device also comprises the fuel gas warning lamp that is arranged on the water heater panel; when combustible gas sensor detected fuel gas, described microprocessor control fuel gas warning lamp flicker was luminous.
