Background
In northern areas, the main mode of heating in winter is completed by the way of radiating by radiators, and actually, radiators are not arranged in each room, so that the room without the radiators can be very cold. Because the radiator can only be installed in a certain side of the indoor space, even if the radiator is installed in some rooms, the space temperature close to the radiator in the room is high, and the space temperature far away from the radiator is relatively low, so that the indoor temperature distribution is quite unbalanced. If the room is left unattended for a long time while heating, energy and money are wasted. And the weather in winter in north is very dry, so that the skin of people is in a water-deficient state, the aging of people is easy to accelerate, and the skin-care mask is extremely unfriendly to people with a poor respiratory system. The conventional humidification mode is that the humidifier is used for humidifying air after people feel that the air is dry, and the humidity rise is a long waiting process, which undoubtedly reduces the use experience of users for the conventional humidifier. Many people also choose to use the air conditioner in winter, however, if the air conditioner is used for a long time, on one hand, the door and the window need to be tightly closed, so that indoor air cannot circulate, the indoor air environment becomes very poor after a long time, the health is affected, and for families, particularly families with children, diseases are easy to generate; on the other hand, turning on the air conditioner for a long time causes the air to be very dry, and if water is not replenished in time, it is very uncomfortable.
Therefore, the intelligent indoor heater based on the voice control is designed, the intelligent heater adopts an infrared sensing technology, once the indoor state is always detected for a period of time, the controller can automatically reduce the supply of the heater to the minimum state, for the room without the heater, the intelligent heater can be pushed to the room for heating, the intelligent heater can detect the indoor temperature and the indoor humidity in real time, thereby adjusting the indoor temperature and the indoor humidity, solving the problems that the indoor heating is not uniform due to the traditional heater and the humidifier humidifies air delay, and can monitor the indoor temperature and the indoor humidity in real time, the intelligent heater is also a chargeable heater, a charging port charges the intelligent heater through a charging module, the intelligent heater is rarely used in other seasons in the north winter, the function realized by the intelligent heater is automatically carried out, and in order to ensure that the intelligent heater is only used in the winter, a switch is thus provided and is controlled by corresponding commands.
