Description
Technical Field
The invention relates to the technical field of air conditioners, in particular to an air conditioner and a control method and a control system of a sleep mode of the air conditioner.
Background
An air conditioner has become one of the essential household appliances in modern homes, and can create a comfortable indoor environment for users. When the air conditioner is operated, a user is in a sleeping state or a non-sleeping state, and the requirements of the user on indoor air quality are different between the sleeping state and the non-sleeping state.
When a user is in a non-sleeping state, indoor activities, such as walking around, are typically performed. The user's indoor activity requires a higher indoor oxygen content than the user's sleep state, and the user's indoor activity causes the indoor air to be in a constantly disturbed state, which helps promote indoor air circulation, thereby substantially equalizing the air quality levels throughout the room. When the user is in a sleeping state, the indoor activity is basically stopped, compared with the non-sleeping state, the indoor oxygen content required by the user is relatively low, and the disturbance frequency of the indoor air is greatly reduced along with the reduction and even stop of the indoor activity, so that the local air quality in the space where the user is located is deteriorated, and the health of the user is adversely affected.
In order to promote the air quality of user space under the sleep state, prior art promotes the new freshness of indoor air through constantly to indoor transport new trend, and promote the circulation of indoor air with the help of the input of new trend, thereby avoid local air quality to worsen, do so and help promoting indoor air quality, however, the energy consumption that the continuous operation new trend function can increase the air conditioner, and there is certain noise, not only can influence user's sleep, and will cause the energy waste when the user requires to be lower to indoor oxygen content.
Therefore, how to provide a control method that is suitable for an indoor environment of sleep and maintains low power consumption of an air conditioner has become an urgent problem to be solved.
Disclosure of Invention
In order to solve the above-mentioned problems in the prior art, that is, to solve the problem of high energy consumption of the sleep control method of the existing air conditioner, a first aspect of the present invention provides a control method of a sleep mode of an air conditioner, where the control method includes:
determining the running time of the sleep mode under the condition that the air conditioner starts the sleep mode; and when the air conditioner is in the sleep mode, the fresh air function and the sterilization function are alternately started in a set mode.
According to the control method of the sleep mode of the air conditioner, after the operation time length of the sleep mode is determined, the fresh air function and the sterilization function are alternately started in the operation time length, so that the freshness of indoor air can be improved by using the input outdoor fresh air in the process of operating the fresh air function, and the oxygen content of the indoor air is improved; the in-process of moving degerming function and the new trend function of the out-of-service can further purify the room air, can drive the room air with the help of the circulation process of indoor return air and keep the circulation state simultaneously, compare with the scheme of continuously opening the new trend function, because the resistance of return air circulation is far less than the resistance of new trend circulation, utilize the return air to flow through the journey to replace the new trend circulation process and make the room air keep the circulation state, and further air-purifying, effectively reduced the energy consumption of air conditioner when having guaranteed the fresh degree of room air like this, can avoid the problem of local air quality decline around the user simultaneously, in addition can also reduce the noise that the new trend operation produced, thereby help improving user's sleep quality.
It should be noted that the operation duration of the sleep mode may be set by the user, or may be automatically set based on the outdoor air quality and/or the indoor air quality, for example, may be set according to air quality parameters such as outdoor oxygen concentration, outdoor temperature, indoor temperature, and indoor oxygen concentration. In addition, the method not only comprises the setting of the total duration of the sleep mode, but also comprises the setting of the running time ratio of the fresh air function and the degerming function. For example, when the outdoor oxygen concentration is high, the operation time of the fresh air function can be appropriately shortened to prolong the operation time of the sterilization function, or when the temperature difference between the outdoor temperature and the indoor temperature is large, the operation time of the fresh air function can be appropriately shortened to appropriately prolong the operation time of the sterilization function, and the like. When the user sets the operation duration by himself, the operation duration can be synchronized with the work and rest habits of the user, great convenience is brought to the user, the air conditioner can automatically stop operating after the operation duration is set, the operation of the user for closing the air conditioner is omitted, and therefore the user can use the air conditioner conveniently. In addition, the sleep mode can be started manually by a user, for example, manually by means of a remote control key, a mobile phone APP and the like, and whether the sleep mode is entered or not can be automatically judged by means of monitoring indoor activity conditions, indoor sound decibels and the like. For example, whether the user is in a sleep state is judged through infrared monitoring to judge whether the user needs to enter the sleep mode.
It should be further noted that, the alternately starting the fresh air function and the bacteria removing function in a set manner may be that the fresh air function is started at the same time or after the sleep mode is started, the fresh air function is closed after the fresh air function runs for a period of time, and the bacteria removing function is started at the same time or after the fresh air function is closed; the sterilization function can be started at the same time or after the sleep mode is started, the sterilization function is closed after the sterilization function runs for a period of time, and the fresh air function is started at the same time or after the sterilization function is closed, and the like.
In the preferred technical scheme of the control method of the sleep mode of the air conditioner, the step of alternately starting the fresh air function and the sterilization function in a set mode specifically comprises the following steps:
when or after the air conditioner starts the sleep mode, firstly, starting a fresh air function; on the premise of firstly starting the fresh air function, the fresh air function and the sterilization function are alternately started.
By firstly starting the fresh air function, the fresh air with enough oxygen content can be provided for the user in the sleep stage with higher oxygen consumption before the user enters deep sleep, so that the user can conveniently and rapidly enter the sleep state.
In the preferable technical scheme of the control method of the sleep mode of the air conditioner, the step of alternately starting the fresh air function and the sterilization function specifically comprises the following steps:
the fresh air function and the sterilization function are alternately started in a mode of setting time at intervals.
Through opening new trend function and degerming function in turn with the mode of interval set time, for example under the condition of at first running new trend function, before switching to the degerming function, can wait for new trend function operation stop completely or stop basically, can wait for new trend fan to stop completely or stop basically specifically, can avoid new trend function and degerming function simultaneously or fan noise big, the problem that the energy consumption is high when basically simultaneously operating, thus reduce system's energy consumption as far as possible, the noise reduction helps building quiet comfortable sleep environment for the user.
The interval time can be measured through experiments, taking the fresh air function switching sterilization function as an example, and the interval time can be set based on the measured time length from the power failure to the stop of the fresh air fan. The sterilization function is switched to the fresh air function in the same way.
In the preferable technical scheme of the control method of the sleep mode of the air conditioner, the operation time of the sterilization function is not less than that of the fresh air function.
By setting in this way, the energy consumption of the air conditioner can be reduced to the maximum extent on the premise of ensuring the freshness of the indoor air.
It should be noted that if the fresh air function is integrated into the air conditioner, the control method reduces the energy consumption of the air conditioner, and if the fresh air function and the air conditioner are configured independently and cooperate with each other, the control method reduces the energy consumption of the whole air conditioning system, and the air conditioning system includes the air conditioner, the fresh air system, and the like.
In a preferable embodiment of the control method for the sleep mode of the air conditioner, the control method further includes:
the indoor target temperature is adjusted while the air conditioner is in the sleep mode.
In order to ensure the comfort of the sleeping environment, the indoor temperature needs to be stably maintained within a certain range, and the indoor temperature can be specifically adjusted by the cooling/heating means operated by the air conditioner. However, when the user is in a sleep state, the human perception of the external environment is somewhat degraded. Taking the refrigeration working condition as an example, the room temperature is 26 ℃ comfortable in the non-sleep state, and the room temperature is 27 ℃ or even 28 ℃ without obvious discomfort in the sleep state, so if the room temperature is continuously taken as the temperature regulation reference, the electric energy is wasted, and the system loss is increased.
In a preferred embodiment of the method for controlling a sleep mode of an air conditioner, the step of "adjusting an indoor target temperature" includes:
the indoor target temperature is adjusted in stages.
When the difference between the adjusted indoor target temperature and the initially set indoor target temperature is large, the air conditioning system generally improves the temperature regulation efficiency by high-speed operation, which may cause problems of high energy consumption, large noise, and the like of the air conditioning system. The indoor target temperature is adjusted in place for many times in a gradual adjustment or other staged adjustment modes by adjusting the indoor target temperature in stages, namely segmenting the temperature difference between the finally adjusted indoor target temperature and the initially set indoor target temperature, so that the energy consumption and the system noise of the system can be reduced, and the discomfort of a user caused by too fast temperature change can be avoided.
It is understood that the stepwise adjustment of the indoor target temperature may be to increase or decrease the indoor target temperature in a stepwise manner, may be to increase and then decrease the indoor temperature, may be to decrease and then increase the indoor temperature, and the like, and the stepwise adjustment refers to a value of the indoor target temperature that is adjusted once every set time.
In a preferred embodiment of the method for controlling a sleep mode of an air conditioner, the step of "adjusting the indoor target temperature in stages" includes:
if the air conditioner operates under the refrigeration working condition, adjusting the indoor target temperature in a gradual rising mode in a staged mode; or
And if the air conditioner operates in a heating condition, the indoor target temperature is adjusted in a step-by-step mode in a manner of first reducing and then increasing.
When the air conditioner is operated under the refrigeration working condition, the indoor target temperature is adjusted in a gradual rising mode, the indoor target temperature can be gradually raised in the process that a user gradually enters deep sleep, so that the overall energy consumption of the air conditioning system can be reduced, and the comfort of the sleep environment of the user can be guaranteed.
When the air conditioner operates in a heating condition, the indoor target temperature is adjusted in a step-by-step mode of firstly reducing and then increasing, so that the indoor target temperature is reduced under the condition that the perception capability of a user is weak in a deep sleep stage, the energy consumption of an air conditioning system can be reduced, and then the indoor target temperature is increased, so that the indoor temperature of the environment where the user is located after waking gradually is close to that before falling asleep, the user is prevented from feeling uncomfortable, the energy consumption of the system is reduced while the environmental comfort is ensured, and the effect of saving energy is achieved.
In a preferred embodiment of the above method for controlling a sleep mode of an air conditioner, the step of "adjusting the indoor target temperature in stages in a manner of decreasing first and then increasing" includes: adjusting the indoor target temperature in stages in a manner that decreases and then increases below the initial indoor target temperature.
The indoor target temperature is adjusted in a mode of firstly reducing and then increasing to be lower than the initial indoor target temperature, so that the energy consumption of the air conditioner can be reduced, and a comfortable indoor environment can be provided for a user.
The second aspect of the present invention further provides a control system for a sleep mode of an air conditioner, which includes a program module, and the program module is configured to execute the control method for the sleep mode of the air conditioner according to any one of the foregoing technical solutions.
The third aspect of the invention also provides an air conditioner, wherein the air conditioner is provided with the control system for the sleep mode of the air conditioner in any one technical scheme.
It can be understood that, since the air conditioner and the sleep mode control system thereof provided by the present invention can implement the sleep mode control method described in the foregoing technical solution, all technical effects of the foregoing control method are provided, and are not described herein again.

The sterilization function in the present invention means sterilization of the indoor return air. The return air is sterilized by a sterilizing device in the return air duct and then is output to the indoor, a return air fan is arranged in the return air duct, and the sterilizing device can be a positive ion generator or a negative ion generator or an ultraviolet sterilizing lamp and the like.
Based on the above air conditioner structure, the method for controlling the sleep mode of the air conditioner provided by this embodiment includes the following steps:
and S10, determining the operation time length of the sleep mode under the condition that the air conditioner starts the sleep mode. Specifically, the user manually starts the sleep mode, and the total operation time of the sleep mode is automatically set according to the work and rest rule of the user. As shown in fig. 1 and 2, the runtime length of the sleep mode in the present embodiment is determined to be 6 h. The user with the regular work and rest can form program memory after continuously setting for a certain number of times, so that the step of repeatedly setting the running time length subsequently by the user can be omitted.
And S20, alternately starting the fresh air function and the sterilization function in a set mode during the sleep mode of the air conditioner.
Specifically, when the air conditioner starts the sleep mode, the fresh air function is firstly started. As shown in fig. 1 or fig. 2, after the fresh air function is turned on, the fresh air fan is controlled to operate at a low speed to reduce the generated noise as much as possible. Under the effect of new trend fan, outdoor new trend gets into indoorly through the new trend wind channel, promotes the oxygen content of indoor air. In addition, the fresh air function is turned on first to make the indoor air have a sufficiently high oxygen content before the user enters deep sleep. After the new trend function continuous operation certain time, if after continuous operation 2h, the oxygen content of room air risees this moment, and the new freshness of room air improves, then closes the new trend function and switches to the degerming function, specifically, opens the degerming function after new trend function bring to rest 5 min. And the sterilization function is continuously operated for a certain time, for example, the sterilization function is switched to the fresh air function and operated after continuously operating for 3 hours. If the operation time of the sterilization function does not reach the set sleep mode operation time length of 6h after the sterilization function operates for 3h, the fresh air function needs to be switched to and continuously operates until the set sleep mode operation time length is reached, and then the sleep mode exits.
In order to further improve the comfort level of the sleeping environment, the control method provided by the embodiment further comprises the cooperative adjustment of the indoor temperature. Specifically, the indoor target temperature is adjusted in stages during the period in which the air conditioner is in the sleep mode.
It should be noted that the indoor temperature adjusting process may be performed only in the fresh air function operating stage, or may be performed in the whole sleep mode operating process.
The temperature adjustment section is described in detail below with reference to fig. 1 and 2.
As shown in fig. 1, the air conditioner is operated in a cooling condition as an example. Simultaneously with or after the sleep mode is started, the indoor target temperature is set to 26 ℃. Taking 26 ℃ as a temperature regulation reference, automatically increasing the indoor target temperature by 0.5 ℃ after the air conditioner operates for 1h in a refrigerating mode, namely increasing the indoor target temperature to 26.5 ℃; and under the condition that the indoor target temperature is set to be 26.5 ℃, after the refrigerating operation is continued for 1h, the indoor target temperature is increased by 0.5 ℃ again, namely the indoor target temperature is increased to be 27 ℃, the operation is continued for 4h under the condition that the indoor target temperature is set to be 27 ℃, and the sleep mode is exited, so that the whole temperature adjusting process is completed.
As shown in fig. 2, taking the air conditioner operating in the heating condition as an example, the indoor target temperature is set to 26 ℃ simultaneously with or after the sleep mode is started. Taking 26 ℃ as a temperature regulation reference, automatically reducing the indoor target temperature to 1 ℃ after the air conditioner is heated for 1h, namely, reducing the indoor target temperature to 25 ℃; under the condition that the indoor target temperature is set to be 25 ℃, after the heating operation is continued for 1h, the indoor target temperature is reduced by 0.5 ℃ again, namely the indoor target temperature is reduced to be 24.5 ℃, after the heating operation is continued for 3h under the condition that the indoor target temperature is set to be 24.5 ℃, the indoor target temperature is increased by 1 ℃, namely the indoor target temperature is adjusted to be 25.5 ℃, and the target temperature is slightly lower than the initial indoor target temperature of 26 ℃, so that the comfort of the temperature is ensured, and the energy consumption is reduced to the maximum extent; and continuing to operate with the target temperature size of 25.5 ℃ until the sleep mode is exited, so that the whole process of temperature regulation is completed.
