Night control logic of indoor air conditioner

Abstract

After entering a night mode, the night control logic of the indoor air conditioner operates according to the following steps that (1) a unit operates according to the temperature T0 set by a user, and the air outlet direction of an indoor unit is adjusted to be downward blowing; (2) when the sleeping time T1 is reached or the indoor environment temperature T3 is detected to be smaller than or equal to T0 within the sleeping time T1, the air outlet direction of the indoor unit is automatically adjusted to be upward air blowing; (3) after the sleeping time T1 is reached, the set temperature of the unit is adjusted to be T0 + T2, and meanwhile the upper limit of the air gear of the indoor unit is adjusted to be the middle air gear; and (4) when the unit meets the temperature-reaching shutdown condition, the outdoor unit is controlled to be shut down, and the indoor unit is kept to operate according to the lowest wind gear. The sleep time T1 and the set temperature correction value T2 can be set according to the requirements of different users, so that the sleep requirements of the different users can be met, and compared with a conventional sleep mode, the personalized sleep requirements of the users are met.

Description

Technical Field

[0001] The invention relates to night control logic of an indoor air conditioner. Background Art

[0002] During the cooling or heating season, the time period when indoor air conditioners are used is most likely to cause people to catch a cold or feel unwell is at night. Due to the difference in indoor and outdoor ambient temperature, the heat dissipation conditions of the house, and the matching degree of the air conditioner capacity with the indoor space, the indoor air conditioner rarely reaches the temperature shutdown condition during the whole night operation, which means that the indoor air conditioner is always running. When the bed is facing the air outlet of the indoor air conditioner, people will be covered by the air outlet of the air conditioner all night, and the body's perception of the outside world will also decrease when people are sleeping soundly. Sometimes they may not cover themselves with a quilt all night, which will lead to headaches, back pains, or fatigue when getting up in the morning. If you set a timer to shut down, you are likely to wake up early in the morning due to the heat.

[0003] To address this problem, air conditioners currently on the market already have a sleep mode. The principle is usually to automatically adjust the set temperature and wind speed of the air conditioner according to the system preset after entering the sleep mode. Then, many users find that this mode does not suit them after using it. The reason is that everyone falls asleep at a different time, the human body's ability to perceive temperature during sleep is different, and everyone sleeps differently. Some people like to cover themselves with a quilt, some people like not to cover themselves with a quilt, etc. Therefore, the sleep mode preset by the manufacturer cannot meet everyone's needs. At the same time, in the breeding industry, many animals have also used air conditioners, and different animals have different sleep needs, and only breeders know what kind of sleeping environment to provide animals to meet their needs. Therefore, conventional air conditioners cannot be used for animal breeding, and air conditioner manufacturers cannot preset sleep modes for all animals' sleep needs. Summary of the invention

[0004] In view of the above problems, the present invention provides a night control logic for an indoor air conditioner, which effectively solves the problems pointed out in the background technology.

[0005] The technical solution adopted by the present invention is:

[0006] A night control logic for an indoor air conditioner, characterized in that after entering the night mode, it operates according to the following steps:

[0007] 1) The unit operates according to the user-set temperature T0, and adjusts the air outlet direction of the indoor unit to downward blowing;

[0008] 2) When the sleeping time T1 is reached or the indoor ambient temperature T3≤T0 is detected during the sleeping time T1 period, the air outlet direction of the indoor unit is automatically adjusted to upward blowing;

[0009] 3) When the sleeping time T1 is reached, the set temperature of the unit is adjusted to T0+T2, and the upper limit of the indoor unit's wind speed is adjusted to the medium wind speed;

[0010] 4) When the unit meets the temperature shutdown conditions, the outdoor unit is controlled to shut down and the indoor unit is kept running at the lowest wind speed.

[0011] The sleeping time T1 and the set temperature correction value T2 are constants, and users can modify them according to their own needs.

[0012] Preferably, when the unit is operating in night mode, if the scheduled shutdown and manual shutdown conditions are met, the unit automatically exits the night mode and shuts down.

[0013] The present invention can set the sleeping time T1 and the set temperature correction value T2 according to the needs of different users, so as to adapt to the sleep needs of different users. Compared with the conventional sleep mode, the present invention meets the personalized sleep needs of users. At the same time, by modifying the sleeping time T1 and the set temperature correction value T2, the user can also better apply it to the breeding industry to meet the sleep needs of animals.

[0014] The sleeping time T1 and the set temperature correction value T2 of the present invention can be preset by software, and when the night mode is turned on, it can be started quickly to simplify the control.

[0015] When entering the night mode, the present invention not only adjusts the wind speed and the set temperature, but also adjusts the wind direction. At the beginning of entering the night mode, downward blowing is adopted to meet the user's demand for a larger air volume. After meeting certain conditions, the downward blowing is changed to upward blowing to avoid direct wind blowing on the human body and improve sleep comfort. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Example 1

[0025] like Figure 1 As shown, a night control logic of an indoor air conditioner, when the user sets the night mode, it is executed according to the night control logic, otherwise it is executed according to the normal control logic. After entering the night mode, it runs according to the following steps:

[0026] 1) The unit operates according to the user-set temperature T0, and adjusts the air outlet direction of the indoor unit to downward blowing;

[0027] 2) When the sleeping time T1 is reached or the indoor ambient temperature T3≤T0 is detected during the sleeping time T1 period, the air outlet direction of the indoor unit is automatically adjusted to upward blowing;

[0028] 3) When the sleeping time T1 is reached, the set temperature of the unit is adjusted to T0+T2, and the upper limit of the indoor unit's wind speed is adjusted to the medium wind speed;

[0029] 4) When the unit meets the temperature shutdown conditions, the outdoor unit is controlled to shut down and the indoor unit is kept running at the lowest wind speed.

[0030] The sleeping time T1 and the set temperature correction value T2 are constants, and users can modify them according to their own needs.

[0031] When the unit is operating in night mode, if the scheduled shutdown and manual shutdown conditions are met, it will automatically exit the night mode and shut down.
