Description

A TV that can automatically detect humidity and intelligently dehumidify

technical field

The utility model relates to a television set, in particular to a television set capable of automatic humidity detection and intelligent dehumidification.

Background technique

As the most popular home appliance, TV sets are widely distributed in various countries around the world. In some areas with relatively high relative humidity, the service life of TVs is generally shorter than that in areas with low humidity. This is because TVs are electrical products. Most of them are circuit components. High humidity means that there is water vapor or even water droplets in the TV. Water has long been known to the world. It is a conductive medium that can cause short circuits between circuit components, thereby affecting the life of the TV. There may also be a risk of electric shock to the user.

Utility model content

The technical problem to be solved by the utility model is to provide a television with automatic humidity detection and intelligent dehumidification suitable for any humidity area in the world.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a TV that can automatically detect humidity and intelligent dehumidification, including a relay connected to an external AC power supply, a power board connected to the output end of the relay, and a power board connected to the power board. The main control chip also includes:

A humidity sensor, used to detect the humidity inside the TV; the humidity sensor is controlled by the main control chip, and controls the on-off of the relay by sending a switch signal;

A built-in heater is used for dehumidification inside the TV and is controlled by the main control chip.

As a further improvement of the technical solution, the TV set also includes a humidity detection light, which is used to indicate the normal working state of the humidity sensor, and is controlled by the main control chip.

Wherein, both the humidity sensor and the heater are powered by an external AC power supply.

Beneficial effects of the utility model: by installing a humidity sensor inside the TV, the internal humidity of the TV can be monitored in real time, and whether to start the TV immediately and normally is determined according to the humidity; No, it can effectively protect the safe use of the TV, ensure that the life of the TV is not affected by the short circuit caused by internal water vapor, and prevent people from getting an electric shock.

Description of drawings

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further.

Fig. 1 is the functional block diagram of the utility model television set;

Fig. 2 is a flowchart of automatic detection of humidity and intelligent dehumidification of the TV set of the present invention.

Detailed ways

As shown in Figure 1, a TV that can automatically detect humidity and intelligent dehumidification includes: a relay 2 connected to an external AC power supply 1; a power board 3 connected to the output end of the relay 2; a main control chip connected to the power board 3 4. The humidity sensor 5 is used to detect the internal humidity of the TV. The humidity sensor 5 is controlled by the main control chip 4, and controls the on-off of the relay 2 by sending a switch signal; the built-in heater 6 is used for dehumidification inside the TV. , and is controlled by the main control chip 4; the humidity detection lamp 7 is used to indicate the normal working state of the humidity sensor 5, and is controlled by the main control chip 4.

In addition, both the humidity sensor 5 and the heater 6 are powered by the external AC power supply 1 .

The utility model TV realizes the working process of automatic detection of humidity and intelligent dehumidification as follows:

(1) Connect the TV to the external AC power supply 1, the humidity sensor 5 starts to detect the humidity inside the TV, and the humidity detection lamp 7 lights up at the same time, indicating the working status of the humidity sensor.

(2), the humidity sensor 5 judges whether the humidity value is greater than the preset safety humidity value; if yes, then enters the next step; otherwise, it sends an opening signal to the relay 2, the relay 2 is turned on, and supplies power to the power board 3, thereby The main control chip 4 controls the TV to be turned on normally, and sends a shutdown signal to the humidity sensor 5 , the heater 6 and the humidity detection lamp 7 .

(3) The humidity sensor 5 sends a starting signal to the heater 6, and the heater 6 starts to dehumidify the inside of the TV.

(4) Every 10 seconds, the humidity sensor 5 detects the humidity value again until the humidity value is less than or equal to the preset safe humidity value, and then sends an open signal to the relay 2, the relay 2 is turned on, and supplies power to the power board 3, thereby The main control chip 4 controls the TV to be turned on normally, and sends a shutdown signal to the humidity sensor 5 , the heater 6 and the humidity detection lamp 7 .

The utility model sets a humidity sensor inside the TV to monitor the humidity inside the TV in real time, and decides whether to start the TV immediately and normally according to the humidity; correspondingly, a built-in heater can determine whether to dehumidify according to the detection of the humidity sensor, which can effectively Protect the safe use of the TV, ensure that the life of the TV is not affected by the short circuit caused by the internal water vapor, and prevent people from getting an electric shock.

The above is only the preferred implementation of the utility model, the utility model is not limited to the above implementation, as long as the technical solutions to achieve the purpose of the utility model by basically the same means are within the scope of protection of the utility model.
