[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0028] Bacteria and mold odors mainly come from the evaporator of the air-conditioning system. When the air-conditioning system is in use, water vapor in the air will condense into water droplets when passing through the evaporator fins; when the air-conditioning system is turned off, the water droplets on the evaporator will not disappear immediately, thus forming a humid, dark, closed environment that is conducive to the growth of bacteria and mold on the evaporator installed in the air duct of the air-conditioning system.

[0029] The invention provides a control method for an air conditioner, which is mainly used to prevent an indoor unit from generating peculiar smell.

[0030] Figure 1 It is a method schematic diagram of an embodiment of the air conditioner control method provided by the present invention.

[0031] like Figure 1 As shown, according to an embodiment of the present invention, the air conditioner control method includes step S110 and step S120, and / or includes step S130.

[0032] Step S110, when the air conditioner is in cooling operation, when it is detected that the indoor temperature reaches the set temperature, it is determined whether the compressor has been shut down due to the indoor temperature reaching the set temperature after the air conditioner is started.

[0033] Step S120, if it is determined that the compressor of the air conditioner has been shut down due to the indoor temperature reaching a set temperature after the air conditioner was turned on, the compressor of the air conditioner is controlled to shut down when it is detected that the indoor temperature reaches the set temperature and lasts for a second preset time.

[0034] Wherein, the air conditioner is controlled to stop when the indoor temperature reaches the set temperature for the first time after the air conditioner is turned on and continues for a first preset time. Specifically, after the air conditioner is turned on and operated for refrigeration, it is detected in real time whether the indoor temperature is less than or equal to the set temperature. When it is detected for the first time that the indoor temperature is less than or equal to the set temperature and the duration reaches the first preset time, the compressor of the air conditioner is controlled to stop. After that, when the indoor temperature is detected to be less than or equal to the set temperature again, it is determined whether the compressor has stopped due to the indoor temperature reaching the set temperature. If it is determined that the compressor has stopped due to the indoor temperature reaching the set temperature, it is necessary to detect that the set temperature is less than or equal to the set temperature for a second preset time before the compressor of the air conditioner is controlled to stop.

[0035] Among them, the second preset time is longer than the first preset time by the third preset time. That is, the second preset time is equal to the sum of the first preset time and the third preset time. In other words, when the indoor temperature is detected to reach the set temperature again, the third preset time is added on the basis of the original need to continue for the first preset time to judge that the indoor temperature is less than or equal to the set temperature, that is, when the indoor temperature is judged to be less than or equal to the set temperature for the second preset time, the compressor is controlled to stop. For example, the first preset time is 10 minutes, and after the indoor temperature has reached the set temperature more than once after the machine is turned on and stopped, the third preset time that needs to be extended relative to the first preset time when the indoor temperature reaches the set temperature again is 60 minutes, and the second preset time is equal to the sum of the first preset time and the second preset time, that is, 70 minutes.

[0036] The present invention prolongs the judgment time of whether the indoor temperature reaches the set temperature, thereby delaying the shutdown time, reducing the number of shutdowns at the temperature point, and correcting the shutdown time at the temperature point to be longer than the normal control logic, that is, the judgment time is lengthened. The odor mainly occurs due to the sudden increase in the evaporator tube temperature caused by the compressor shutdown, and the sudden change of the evaporator fin condenser water. Therefore, reducing the number of shutdowns at the temperature point can reduce the possibility of odor generation.

[0037] Furthermore, if it is determined that the compressor of the air conditioner has not stopped due to the indoor temperature reaching the set temperature after it was started, then when it is detected that the indoor temperature reaches the set temperature and lasts for a first preset time, the compressor of the air conditioner is controlled to stop, and the indoor fan of the air conditioner is controlled to continue to run at the set wind speed.

[0038] Specifically, if it is determined that the compressor has not stopped due to the indoor temperature reaching the set temperature after the air conditioner is turned on, it means that the indoor temperature has not reached the set temperature and continued for the first preset time after the air conditioner is turned on, then when the indoor temperature reaches the set temperature and continues for the first preset time, the compressor of the air conditioner is controlled to stop, and the indoor fan continues to run at the set wind speed. That is, the compressor stops when the indoor temperature reaches the set temperature and continues for the first preset time for the first time after the air conditioner is turned on.

[0039] Furthermore, after the compressor of the air conditioner is controlled to stop, when the indoor temperature rises to above a preset temperature value of the set temperature, the compressor is restarted and the indoor fan is controlled to run at a preset minimum speed.

[0040] Specifically, after the air conditioner is turned on and operated, when the indoor temperature is detected for the first time to reach the set temperature and lasts for the first preset time, the compressor of the air conditioner is controlled to stop. When the indoor temperature rises to above the preset temperature value of the set temperature, the compressor is restarted and the indoor fan is controlled to run at the preset minimum speed. Thereafter, when it is detected again that the indoor temperature is less than or equal to the set temperature, the duration of the indoor temperature being less than or equal to the set temperature is judged to be extended by a third preset time, and the speed of the indoor fan is adjusted to the preset minimum speed. The preset minimum speed can specifically be the speed of the preset minimum wind speed, such as the low wind speed. The low speed operation of the indoor fan can reduce the output cooling capacity and maintain the indoor temperature, slowing down or avoiding the shutdown when the set temperature point is reached again.

[0041] Figure 2 FIG. 1 is a flow chart of a specific embodiment of the air conditioner control method according to the present invention. Figure 2 As shown, the air conditioner is turned on for cooling. When the indoor temperature reaches the set temperature, it is determined whether the temperature point has been reached and the system has stopped once. If the temperature point has been reached and the system has stopped once, the shutdown temperature determination time is extended by 60 minutes. When the system is restarted, the fan speed is adjusted to the lowest speed.

[0042] Step S130, during the process of starting up the air conditioner or restoring it after being shut down, or during the process of the air conditioner compressor shutting down due to the indoor temperature reaching a set temperature or shutting down due to a malfunction, control the air guide plate of the air conditioner to run to a preset anti-odor position and / or control the indoor fan of the air conditioner to run at a preset minimum speed.

[0043] Specifically, when the air conditioner is turned on or the compressor is restarted after being shut down, the air guide plate is controlled to move to the preset anti-odor position, and / or the indoor fan is controlled to run at a preset minimum speed, or when the air conditioner compressor is shut down due to the indoor temperature reaching a set temperature or a malfunction, the air guide plate is controlled to move to the preset anti-odor position, and / or the indoor fan is controlled to run at a preset minimum speed.

[0044] The preset anti-odor position can specifically be an upward air supply position, or a downward air supply position, and the position can be raised or lowered according to the situation. This position can change the direction of the airflow so that the air-conditioning airflow direction avoids the user and is as far away from the user's mouth and nose as possible. After the odor gradually diffuses, the concentration becomes lower, and the user's odor sensation is weakened or not obvious, so try to supply air to the uppermost ceiling, or to the lowest ground. The preset minimum speed can specifically be a preset minimum wind speed, such as a low wind speed. The present invention adopts a method of simultaneously adjusting and controlling wind speed and wind direction to prevent users from smelling odors.

[0045] Figure 3 It is a method schematic diagram of another embodiment of the air conditioner control method provided by the present invention.

[0046] like Figure 3 As shown, according to another embodiment of the present invention, the air conditioner control method further includes step S140.

[0047] Step S140, when the indoor heat exchanger tube temperature reaches a preset temperature and / or the compressor operation time reaches a fourth preset time, the air guide plate is controlled to return to a set position and / or the indoor fan is controlled to return to a set speed.

[0048] Specifically, during the process of starting up the air conditioner or resuming starting up after shutdown, after controlling the air guide plate to run to a preset anti-odor position and / or controlling the indoor fan to run at a preset minimum speed, when the indoor heat exchanger tube temperature drops to a certain temperature and / or the compressor has run for a certain period of time, the air conditioner will no longer produce odor, so the air guide plate can be controlled to return to the set position and / or the indoor fan can be controlled to return to the set speed.

[0049] During the process in which the compressor of the air conditioner shuts down due to the indoor temperature reaching the set temperature or malfunctioning, after controlling the air guide plate to run to the preset anti-odor position, and / or controlling the indoor fan to run at the preset minimum speed, when the compressor is restarted, the indoor heat exchanger tube temperature drops to a certain temperature and / or the compressor has been running for a certain period of time, the air conditioner will no longer produce odor, so the air guide plate can be controlled to return to the set position and / or the indoor fan can be controlled to return to the set speed.

[0050] For example, when the indoor heat exchanger tube temperature is less than or equal to 18°C ​​or the compressor running time reaches 8 minutes, the air guide plate and / or the indoor fan speed returns to normal, that is, the air guide plate returns to the set position and / or the indoor fan returns to the set speed.

[0051] According to the above-mentioned embodiment of the present invention, even if the temperature point is reached and the machine is shut down or started up, which is likely to generate odor, anti-odor treatment can be performed through the air guide plate control logic and the indoor fan speed control logic to prevent the odorous air from blowing near the human respiratory tract, thereby alleviating the problem of odor release from the air conditioner indoor unit.

[0052] In order to clearly illustrate the technical solution of the present invention, the execution process of the air conditioner control method provided by the present invention is described below with reference to a specific embodiment.

[0053] Figure 4 FIG. 2 is a flow chart of another specific embodiment of the air conditioning control method provided by the present invention. Figure 4 As shown, after the air conditioner is started, the air guide plate first runs to the preset anti-odor position, and the indoor fan runs at a low wind speed. When the indoor heat exchanger tube temperature is less than or equal to 18°C ​​or the compressor running time reaches 8 minutes, the air guide plate and the indoor fan speed return to normal. When the indoor temperature reaches the set temperature and the compressor stops, the air guide plate first runs to the preset anti-odor position, and the indoor fan runs at a low wind speed. When the compressor is restarted, the indoor heat exchanger tube temperature is less than or equal to 18°C ​​or the compressor running time reaches 8 minutes, the air guide plate and the indoor fan speed return to normal.

[0054] The invention also provides a control device for an air conditioner.

[0055] Figure 5 FIG. 1 is a structural block diagram of an embodiment of the air conditioner control device provided by the present invention. Figure 5 As shown, the control device 100 includes: a detection unit 110 , a judgment unit 120 and a first control unit 130 , and / or includes: a second control unit 140 .

[0056] The detection unit 110 is used to detect whether the indoor temperature reaches the set temperature.

[0057] The judgment unit 120 is used to judge whether the compressor has been shut down due to the indoor temperature reaching the set temperature after the air conditioner was started up when the detection unit detects that the indoor temperature has reached the set temperature during the cooling operation of the air conditioner.

[0058] The first control unit 130 is used to control the compressor of the air conditioner to stop when the indoor temperature reaches the set temperature and lasts for a second preset time, if the judgment unit judges that the compressor has stopped due to the indoor temperature reaching the set temperature after the air conditioner is turned on, wherein the second preset time is longer than the first preset time by a third preset time;

[0059] Wherein, the first control unit controls the compressor of the air conditioner to stop when the indoor temperature reaches the set temperature and lasts for a first preset time for the first time after the air conditioner is turned on.

[0060] Specifically, after the air conditioner is started to run, it is detected in real time whether the indoor temperature is less than or equal to the set temperature. When it is detected for the first time that the indoor temperature is less than or equal to the set temperature and the duration reaches a first preset time, the compressor of the air conditioner is controlled to stop. When it is detected again that the indoor temperature is less than or equal to the set temperature, it is determined whether the compressor has been shut down due to the indoor temperature reaching the set temperature. If it is determined that the compressor has been shut down due to the indoor temperature reaching the set temperature, it is necessary to detect that the set temperature is less than or equal to the set temperature for a second preset time before the compressor of the air conditioner is controlled to stop.

[0061] Among them, the second preset time is longer than the first preset time by the third preset time. That is, the second preset time is equal to the sum of the first preset time and the third preset time. In other words, when the indoor temperature is detected to reach the set temperature again, the third preset time is added on the basis of the original need to continue for the first preset time to judge that the indoor temperature is less than or equal to the set temperature, that is, when the indoor temperature is judged to be less than or equal to the set temperature for the second preset time, the compressor is controlled to stop. For example, the first preset time is 10 minutes, and after the indoor temperature has reached the set temperature more than once after the machine is turned on and stopped, the third preset time that needs to be extended relative to the first preset time when the indoor temperature reaches the set temperature again is 60 minutes, and the second preset time is equal to the sum of the first preset time and the second preset time, that is, 70 minutes.

[0062] The present invention prolongs the judgment time of whether the indoor temperature reaches the set temperature, thereby delaying the shutdown time, reducing the number of shutdowns at the temperature point, and correcting the shutdown time at the temperature point to be longer than the normal control logic, that is, the judgment time is lengthened. The odor mainly occurs due to the sudden increase in the evaporator tube temperature caused by the compressor shutdown, and the sudden change of the evaporator fin condenser water. Therefore, reducing the number of shutdowns at the temperature point can reduce the possibility of odor generation.

[0063] Furthermore, the first control unit 140 is also used for: if the second judgment unit 120 determines that the compressor has not stopped due to the indoor temperature reaching a set temperature after the air conditioner was started, then when the first detection unit 110 detects that the indoor temperature has reached the set temperature and lasts for a first preset time, the compressor of the air conditioner is controlled to stop, and the indoor fan of the air conditioner is controlled to continue to run at the set wind speed.

[0064] Specifically, if it is determined that the compressor has not stopped due to the indoor temperature reaching the set temperature after the air conditioner is turned on, it means that the indoor temperature has not reached the set temperature and continued for the first preset time after the air conditioner is turned on, then when the indoor temperature reaches the set temperature and continues for the first preset time, the compressor of the air conditioner is controlled to stop, and the indoor fan continues to run at the set wind speed. That is, the compressor stops when the indoor temperature reaches the set temperature and continues for the first preset time for the first time after the air conditioner is turned on.

[0065] Furthermore, the first control unit 130 is also used to: after controlling the compressor of the air conditioner to stop, when the indoor temperature rises to above a preset temperature value of the set temperature, the compressor is restarted and the indoor fan is controlled to run at a preset minimum speed.

[0066] Specifically, after the air conditioner is turned on and operated, when the indoor temperature is detected for the first time to reach the set temperature and lasts for the first preset time, the compressor of the air conditioner is controlled to stop. When the indoor temperature rises to above the preset temperature value of the set temperature, the compressor is restarted and the indoor fan is controlled to run at the preset minimum speed. Thereafter, when it is detected again that the indoor temperature is less than or equal to the set temperature, the duration of the indoor temperature being less than or equal to the set temperature is extended by a third preset time, and the speed of the indoor fan is adjusted to the preset minimum speed. The preset minimum speed can specifically be a preset minimum wind speed, such as a low wind speed. The low speed operation of the indoor fan can reduce the output cooling capacity and maintain the indoor temperature, slowing down or avoiding the shutdown when the set temperature point is reached again.

[0067] Figure 2 FIG. 1 is a flow chart of a specific embodiment of the air conditioner control method according to the present invention. Figure 2 As shown, the air conditioner is turned on for cooling. When the indoor temperature reaches the set temperature, it is determined whether the temperature point has been reached and the system has stopped once. If the temperature point has been reached and the system has stopped once, the shutdown temperature determination time is extended by 60 minutes. When the system is restarted, the fan speed is adjusted to the lowest speed.

[0068] The second control unit 140 is used to control the air guide plate of the air conditioner to run to a preset anti-odor position and / or control the indoor fan of the air conditioner to run at a preset minimum speed during the process of starting up the air conditioner or restoring it after shutdown, or when the compressor of the air conditioner shuts down because the indoor temperature reaches a set temperature or shuts down due to a malfunction.

[0069] Specifically, when the air conditioner is turned on or the compressor is shut down and then restarted, the second control unit 140 controls the air guide plate to run to a preset anti-odor position, and / or controls the indoor fan to run at a preset minimum speed, or when the air conditioner compressor shuts down due to the indoor temperature reaching a set temperature or a malfunction, the second control unit 140 controls the air guide plate to run to a preset anti-odor position, and / or controls the indoor fan to run at a preset minimum speed.

[0070] The preset anti-odor position can specifically be an upward air supply position, or a downward air supply position, and the position can be raised or lowered according to the situation. This position can change the direction of the airflow so that the air-conditioning airflow direction avoids the user and is as far away from the user's mouth and nose as possible. After the odor gradually diffuses, the concentration becomes lower, and the user's odor sensation is weakened or not obvious, so try to supply air to the uppermost ceiling, or to the lowest ground. The preset minimum speed can specifically be a preset minimum wind speed, such as a low wind speed. The present invention adopts a method of simultaneously adjusting and controlling wind speed and wind direction to prevent users from smelling odors.

[0071] Furthermore, the second control unit 140 is also used to: after controlling the air guide plate of the air conditioner to run to a preset anti-odor position and / or controlling the indoor fan of the air conditioner to run at a preset minimum speed, when the indoor heat exchanger tube temperature reaches a preset temperature and / or the compressor running time reaches a fourth preset time, control the air guide plate to return to the set position and / or control the indoor fan to return to the set speed.

[0072] Specifically, during the process of starting up the air conditioner or restoring the air conditioner after stopping, after controlling the air guide plate to run to the preset anti-odor position and / or controlling the indoor fan to run at the preset minimum speed, when the indoor heat exchanger tube temperature drops to a certain temperature and / or the compressor runs for a certain period of time, the air conditioner will no longer produce odor, so the air guide plate can be controlled to return to the set position and / or the indoor fan can be controlled to return to the set speed. For example, when the indoor heat exchanger tube temperature is less than or equal to 18°C ​​or the compressor runs for 8 minutes, the air guide plate and / or the indoor fan speed returns to normal, that is, the air guide plate returns to the set position and / or the indoor fan returns to the set speed.

[0073] During the process in which the compressor of the air conditioner shuts down due to the indoor temperature reaching the set temperature or malfunctioning, after controlling the air guide plate to run to the preset anti-odor position, and / or controlling the indoor fan to run at the preset minimum speed, when the compressor is restarted, the indoor heat exchanger tube temperature drops to a certain temperature and / or the compressor has been running for a certain period of time, the air conditioner will no longer produce odor, so the air guide plate can be controlled to return to the set position and / or the indoor fan can be controlled to return to the set speed.

[0074] For example, when the indoor heat exchanger tube temperature is less than or equal to 18°C ​​or the compressor running time reaches 8 minutes, the air guide plate and / or the indoor fan speed returns to normal, that is, the air guide plate returns to the set position and / or the indoor fan returns to the set speed.

[0075] The present invention also provides a storage medium corresponding to the air conditioner control method, on which a computer program is stored, and when the program is executed by a processor, the steps of any of the above methods are implemented.

[0076] The present invention also provides an air conditioner corresponding to the air conditioner control method, comprising a processor, a memory, and a computer program stored in the memory and executable on the processor, wherein the processor implements the steps of any of the aforementioned methods when executing the program.

[0077] The present invention also provides an air conditioner corresponding to the control device of the air conditioner, comprising any of the control devices of the air conditioner described above.

[0078] The present invention also provides a computer program product corresponding to the air conditioner control method, comprising a computer program, and when the computer program is executed by a processor, the steps of any of the aforementioned methods are implemented.

[0079] Accordingly, the solution provided by the present invention prolongs the time for judging whether the indoor temperature has reached the set temperature, thereby delaying the shutdown time and reducing the number of shutdowns when the temperature point is reached, thereby reducing the possibility of odor generation.
