Detailed Description
In the description of the present invention, it should be noted that the terms "inside", "outside", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and operate, and thus, should not be construed as limiting the present invention.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," "contacting," and "communicating" are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The control method of the air conditioner is used for solving the problems that whether an existing air conditioner achieves an automatic shutdown function or not is judged through a door lock or hardware equipment additionally arranged on the air conditioner, and user cost is increased due to the fact that the hardware equipment is additionally arranged. The air conditioner of the present embodiment is provided with an automatic shutdown function, as shown in the control flowchart of fig. 1, the control method of the present embodiment includes steps S1 to S3, where:
s1, judging whether the current indoor environment is a closed space according to the temperature difference between the indoor environment temperature and the outdoor environment temperature and the temperature difference between the indoor environment temperature and the set temperature in the operation process of the air conditioner;
s2, if the current indoor environment is a non-closed space, judging that the set condition for executing the automatic shutdown function is reached; if the current indoor environment is a closed space, determining whether a set condition for executing the automatic power-off function is met according to the difference value of the indoor environment temperature and the set temperature;
and S3, controlling the air conditioner to automatically shut down when the set condition for executing the automatic shutdown function is reached.
In this embodiment, when the user leaves the room for a long time, the door or the window is opened for ventilation in most cases, if the user forgets to close the air conditioner, the indoor temperature cannot reach the set temperature, and then the air conditioner is kept on meaninglessly and only the energy consumption is increased unnecessarily, so that the air conditioner is controlled to automatically close the air conditioner when the indoor environment is judged to be an airtight space. When the indoor environment is an unsealed space, the indoor environment temperature and the outdoor environment temperature converge, namely the temperature difference between the indoor environment temperature and the outdoor environment temperature is smaller and smaller; meanwhile, the temperature difference between the indoor environment temperature and the user setting temperature is larger and larger, and therefore, the present embodiment determines whether the current indoor environment is the airtight space or not by the temperature difference between the indoor environment temperature and the outdoor environment temperature and the temperature difference between the indoor environment temperature and the setting temperature. When the indoor environment is judged to be the non-closed space, the air conditioner is not needed to be continuously operated at the moment, which shows that the set condition for executing the automatic shutdown function is reached at the moment, and the air conditioner is controlled to be automatically shut down. When the indoor environment is judged to be the non-closed space, the indoor environment temperature is close to the set temperature and tends to be stable, therefore, whether the set condition for executing the automatic shutdown function is achieved or not is determined according to the difference value of the indoor environment temperature and the set temperature, when the set condition for executing the automatic shutdown function is achieved, the air conditioner is controlled to be automatically shut down, and if the set condition for executing the automatic shutdown function is not achieved, the air conditioner is controlled to continue to operate.
The control method of the embodiment can solve the problem that when a user forgets to turn off the air conditioner and leaves a room, different control logics are adopted for controlling the non-closed space and the closed space as the indoor environment, and the energy waste is effectively solved. In addition, the control logic is improved on the basis of an indoor environment temperature sensor and an outdoor environment temperature sensor of the existing air conditioner, and the hardware cost is not required to be increased.
