[0026] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described clearly and completely below with reference to the embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0027] It should be noted that the terms "first", "second", and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or a chronological sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to the process, method, product or device.

[0028] The bacterial and mold odor mainly comes from the evaporator of the air conditioning system. When the air conditioning system is in use, the water vapor in the air will condense into water droplets when passing through the evaporator fins; after the air conditioning system is turned off, the water droplets on the evaporator will not disappear immediately, thereby forming a humid, dark and closed environment on the evaporator installed in the air conditioning system air duct, which is conducive to the growth of bacteria and mold.

[0029] The present application provides a control method of an air conditioner. The method is mainly used to prevent the indoor unit from producing odor.

[0030] Figure 1 is a method diagram of an embodiment of the control method of the air conditioner according to the present application.

[0031] As shown in Figure 1 According to one embodiment of the present application, the control method of the air conditioner comprises steps S110 and S120, and / or step S130.

[0032] In step S110, when the indoor temperature detected reaches the set temperature during the air conditioner cooling operation, it is determined whether the compressor has stopped due to the indoor temperature reaching the set temperature after the air conditioner is started.

[0033] In step S120, if it is determined that the compressor has stopped due to the indoor temperature reaching the set temperature after the air conditioner is started, the compressor of the air conditioner is controlled to stop when the indoor temperature detected reaches the set temperature and lasts for a second preset time.

[0034] In the first detection of the indoor temperature reaching the set temperature and lasting for a first preset time after the air conditioner is started, the air conditioner is controlled to stop. Specifically, after the air conditioner is started to cool, the indoor temperature is detected in real time. When the indoor temperature is detected for the first time to be less than or equal to the set temperature and lasts for a first preset time, the compressor of the air conditioner is controlled to stop. When the indoor temperature is detected again to be less than or equal to the set temperature, 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, the compressor is controlled to stop only when the set temperature is detected to be less than or equal to the set temperature for a second preset time.

[0035] In the first detection of the indoor temperature reaching the set temperature and lasting for a first preset time after the air conditioner is started, the air conditioner is controlled to stop. Specifically, after the air conditioner is started to cool, the indoor temperature is detected in real time. When the indoor temperature is detected for the first time to be less than or equal to the set temperature and lasts for a first preset time, the compressor of the air conditioner is controlled to stop. When the indoor temperature is detected again to be less than or equal to the set temperature, 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, the compressor is controlled to stop only when the set temperature is detected to be less than or equal to the set temperature for a second preset time.

[0036] The present application prolongs the determination time of the indoor temperature reaching the set temperature, thereby delaying the stop time, reducing the number of stops at the temperature point, and correcting the time of stopping at the temperature point to be longer than the normal control logic, i.e., the determination time is prolonged. The appearance of odors is mainly caused by the sudden increase in the temperature of the evaporator pipe and the sudden change in the condenser water during the process of the compressor stopping, so reducing the number of stops at the temperature point can reduce the possibility of preventing the generation of odors.

[0037] Further, if it is judged that the compressor has not stopped due to the indoor temperature reaching the set temperature after the air conditioner is started, the compressor is stopped when the indoor temperature reaches the set temperature and lasts for the first preset time, and the indoor fan is controlled to continue operating at the set wind speed.

[0038] Specifically, if it is judged that the compressor has not stopped due to the indoor temperature reaching the set temperature after the air conditioner is started, it means that the indoor temperature has not reached the set temperature and lasted for the first preset time after the air conditioner is started. Therefore, when the indoor temperature reaches the set temperature and lasts for the first preset time, the compressor is stopped, and the indoor fan continues to operate at the set wind speed. This is the first time that the compressor is stopped when the indoor temperature reaches the set temperature and lasts for the first preset time after the air conditioner is started.

[0039] Further, after the compressor is stopped, when the indoor temperature rises to a preset temperature value above the set temperature, the compressor is started, and the indoor fan is controlled to operate at a preset minimum speed.

[0040] Specifically, after the compressor is stopped when the indoor temperature reaches the set temperature and lasts for the first preset time after the air conditioner is started, when the indoor temperature rises to a preset temperature value above the set temperature, the compressor is started, and the indoor fan is controlled to operate at a preset minimum speed. After that, when the indoor temperature is detected to be less than or equal to the set temperature again, it is judged that the duration of the indoor temperature being less than or equal to the set temperature is extended by a third preset time, and the indoor fan speed is adjusted to a preset minimum speed. The preset minimum speed can be the speed of the preset minimum wind speed, for example, 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 occurrence of stopping at the set temperature point again.

[0041] Figure 2 The flowchart of a specific embodiment of the control method of the air conditioner according to the present application is shown. The above steps can be referred to Figure 2 As shown in the figure, the air conditioner is started to cool down, and when the indoor temperature reaches the set temperature, it is judged whether it has occurred once to stop at the temperature point. If it has occurred once to stop at the temperature point, the stop temperature judgment time is extended by 60 minutes, and the fan speed is adjusted to the minimum speed when the air conditioner is started.

[0042] In step S130, during the starting process of the air conditioner or the restarting process after stopping, or during the process of stopping or malfunctioning of the compressor of the air conditioner due to the indoor temperature reaching the set temperature, the air deflector of the air conditioner is controlled to operate to a preset odor prevention position, and / or the indoor fan of the air conditioner is controlled to operate at a preset minimum speed.

[0043] Specifically, when the air conditioner is started or the compressor is restarted after shutdown, the control of the air deflector to the preset odor-preventing position and / or the control of the indoor fan to run at the preset minimum speed, or during the process that the compressor of the air conditioner is stopped due to the indoor temperature reaching the set temperature or a fault, the control of the air deflector to the preset odor-preventing position and / or the control of the indoor fan to run at the preset minimum speed.

[0044] The preset odor-preventing position can be an upward air supply position or a downward air supply position, which can be raised or lowered according to the situation. This position can change the air flow direction so that the air flow direction of the air conditioner avoids the user and is far away from the user's mouth and nose position, and the odor gradually diffuses and the concentration becomes low, so the user's odor feeling is weakened or not obvious. Therefore, the air is supplied to the uppermost ceiling or the lowermost ground. The preset minimum speed can be a preset minimum wind speed, for example, a low wind speed. The air speed + air direction adjustment and control mode adopted by the present application can avoid the user smelling the odor.

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

[0046] As shown in Figure 3 According to another embodiment of the present application, the control method of the air conditioner further includes step S140.

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

[0048] Specifically, during the starting process of the air conditioner or the restarting process after shutdown, after the control of the air deflector to the preset odor-preventing position and / or the control of the indoor fan to run at the preset minimum speed, when the indoor heat exchanger tube temperature decreases to a certain temperature and / or the compressor operates for a certain time, the air conditioner will no longer produce odor, so the air deflector 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 that the compressor of the air conditioner is stopped due to the indoor temperature reaching the set temperature or a fault, after the control of the air deflector to the preset odor-preventing position and / or the control of the indoor fan to run at the preset minimum speed, when the indoor heat exchanger tube temperature decreases to a certain temperature and / or the compressor operates for a certain time after the compressor is restarted, the air conditioner will no longer produce odor, so the air deflector 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℃ or the compressor running time reaches 8 minutes, the air deflector and / or the indoor fan speed is restored to the normal state, i.e., the air deflector is restored to the set position and / or the indoor fan is restored to the set speed.

[0051] According to the above embodiments of the present application, even if the situation of reaching the temperature point to stop or start the compressor and the like occurs, the anti-odor treatment can be performed through the air deflector control logic and the indoor fan speed control logic, the air with odor is avoided to be blown to the respiratory tract of a person, and the problem of releasing odor by the air conditioner indoor unit can be alleviated.

[0052] To clearly illustrate the technical scheme of the present application, the execution flow of the control method of the air conditioner provided by the present application is described below with one specific embodiment.

[0053] Figure 4 is a flow diagram of another specific embodiment of the control method of the air conditioner provided by the present application. As shown in Figure 4 , after the air conditioner is started to run, the air deflector is first run to the preset anti-odor position, the indoor fan is run at a low speed, when the indoor heat exchanger tube temperature is less than or equal to 18℃ or the compressor running time reaches 8 minutes, the air deflector and the indoor fan speed are restored to the normal state, when the indoor temperature reaches the set temperature and the compressor is stopped, the air deflector is first run to the preset anti-odor position, the indoor fan is run at a low speed, when the compressor is started again, the indoor heat exchanger tube temperature is less than or equal to 18℃ or the compressor running time reaches 8 minutes, the air deflector and the indoor fan speed are restored to the normal state.

[0054] The present application also provides a control device of an air conditioner.

[0055] Figure 5 is a structural block diagram of one embodiment of the control device of the air conditioner provided by the present application. As shown in Figure 5 , the control device 100 comprises a detection unit 110, a judgment unit 120 and a first control unit 130, and / or comprises a second control unit 140.

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

[0057] The judgment unit 120 is configured to, when the detection unit detects that the indoor temperature reaches the set temperature during the air conditioner cooling operation, judge whether the air conditioner is started to run after the compressor is stopped due to the indoor temperature reaching the set temperature.

[0058] The first control unit 130 is configured to control the compressor of the air conditioner to stop when the detection unit detects that 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 started to run.

[0059] The first control unit controls the compressor of the air conditioner to stop when the detection unit detects that the indoor temperature reaches the set temperature and lasts for a first preset time after the air conditioner is started to run.

[0060] Specifically, after the air conditioner is started to run in the cooling mode, it is detected in real time whether the indoor temperature is less than or equal to the set temperature. When the indoor temperature is detected for the first time to be less than or equal to the set temperature and lasts for a first preset time, the compressor of the air conditioner is controlled to stop. When the indoor temperature is detected again to be less than or equal to the set temperature, it is judged whether the compressor has stopped due to the indoor temperature reaching the set temperature. If it is judged that the compressor has stopped due to the indoor temperature reaching the set temperature, the compressor of the air conditioner is controlled to stop only when the set temperature is detected to be less than or equal to the set temperature for a second preset time.

[0061] The second preset time is longer than the first preset time by a third preset time. That is, the second preset time is equal to the sum of the first preset time and the third preset time. That is to say, when the indoor temperature is detected again to reach the set temperature, the third preset time is added to the original first preset time for judging that the indoor temperature is less than or equal to the set temperature, that is, the compressor is controlled to stop when the indoor temperature is detected to be less than or equal to the set temperature for a second preset time. For example, the first preset time is 10 minutes, and the third preset time that needs to be extended relative to the first preset time when the indoor temperature is detected again to reach the set temperature after the compressor has stopped due to the indoor temperature reaching the set temperature for more than once is 60 minutes. 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 application prolongs the judgment time of the indoor temperature reaching the set temperature, thereby delaying the stop time, reducing the number of times of reaching the temperature point to stop, and correcting the time of reaching the temperature point to stop to be longer than the normal control logic, that is, the judgment time is prolonged. The generation of peculiar smell is mainly caused by the process that the compressor stops and the temperature of the evaporator pipe suddenly becomes high, and the water of the evaporator fin condenser suddenly changes. Therefore, reducing the number of times of reaching the temperature point to stop can reduce the possibility of preventing the generation of peculiar smell.

[0063] Further, the first control unit 140 is further configured to: if the second judging unit 120 judges that the compressor has not stopped due to the indoor temperature reaching the set temperature after the air conditioner is started, control the compressor of the air conditioner to stop and control the indoor fan of the air conditioner to continue to operate at the set wind speed when the first detecting unit 110 detects that the indoor temperature reaches the set temperature and lasts for the first preset time.

[0064] Specifically, if it is judged that the compressor has not stopped due to the indoor temperature reaching the set temperature after the air conditioner is started, it means that the indoor temperature has not reached the set temperature and lasted for the first preset time after the air conditioner is started. Therefore, when the indoor temperature reaches the set temperature and lasts for the first preset time, the compressor is controlled to stop and the indoor fan continues to operate at the set wind speed. This is the first time that the compressor is controlled to stop when the indoor temperature reaches the set temperature and lasts for the first preset time after the air conditioner is started.

[0065] Further, the first control unit 130 is further configured to: after the compressor is controlled to stop, when the indoor temperature rises to a preset temperature value of the set temperature, the compressor is controlled to start and the indoor fan is controlled to operate at a preset minimum speed.

[0066] Specifically, after the compressor is controlled to stop when the indoor temperature reaches the set temperature and lasts for the first preset time for the first time after the air conditioner is started, when the indoor temperature rises to a preset temperature value of the set temperature, the compressor is controlled to start and the indoor fan is controlled to operate at a preset minimum speed. After that, when the indoor temperature is detected to be less than or equal to the set temperature again, it is judged that 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 be a preset minimum wind speed, for example, a low wind speed. The low-speed operation of the indoor fan can reduce the output cooling capacity and maintain the indoor temperature, so as to slow down or avoid the occurrence of stopping again at the set temperature point.

[0067] Figure 2 The flowchart of a specific embodiment of the control method of the air conditioner according to the present application is shown in the figure. The above steps can be referred to Figure 2 As shown in the figure, the air conditioner is started to cool down. When the indoor temperature reaches the set temperature, it is judged whether the temperature point has been reached once. If the temperature point has been reached once, the stop temperature judgment time is extended by 60 minutes, and the fan speed is adjusted to the minimum speed when the air conditioner is started.

[0068] The second control unit 140 is configured to control the air deflector of the air conditioner to run to a preset odor-preventing position and / or control the indoor fan of the air conditioner to run at a preset minimum rotating speed during the starting process of the air conditioner or after the air conditioner is stopped and then restarted, or during the process that the compressor of the air conditioner is stopped due to the indoor temperature reaching a set temperature or due to a fault.

[0069] Specifically, when the air conditioner is started or the compressor is stopped and then restarted, the second control unit 140 controls the air deflector to run to a preset odor-preventing position and / or controls the indoor fan to run at a preset minimum rotating speed, or during the process that the compressor of the air conditioner is stopped due to the indoor temperature reaching a set temperature or due to a fault, the second control unit 140 controls the air deflector to run to a preset odor-preventing position and / or controls the indoor fan to run at a preset minimum rotating speed.

[0070] The preset odor-preventing position can be an upward air supply position or a downward air supply position, which can be raised or lowered according to the situation. The position can change the air flow direction so that the air flow direction of the air conditioner avoids the user and is far away from the mouth and nose position of the user, and the odor gradually diffuses and the concentration becomes low, so the odor feeling of the user is weakened or not obvious. Therefore, the air is supplied to the uppermost ceiling or the lowermost ground. The preset minimum rotating speed can be a preset minimum wind gear, for example, a low wind gear. The air speed + air direction adjustment and control mode adopted by the air conditioner can avoid the user smelling the odor.

[0071] Further, the second control unit 140 is further configured to, after controlling the air deflector of the air conditioner to run to a preset odor-preventing position and / or controlling the indoor fan of the air conditioner to run at a preset minimum rotating speed, control the air deflector to return to a set position and / or control the indoor fan to return to a set rotating speed when the indoor heat exchanger tube temperature reaches a preset temperature and / or the compressor operating time reaches a fourth preset time.

[0072] Specifically, after the air deflector is controlled to run to a preset odor-preventing position and / or the indoor fan is controlled to run at a preset minimum rotating speed during the starting process of the air conditioner or after the air conditioner is stopped and then restarted, when the indoor heat exchanger tube temperature decreases to a certain temperature and / or the compressor operates for a certain time, the air conditioner will no longer produce odor, so the air deflector can be controlled to return to a set position and / or the indoor fan can be controlled to return to a set rotating speed. For example, when the indoor heat exchanger tube temperature is less than or equal to 18℃ or the compressor operating time reaches 8 minutes, the rotating speed of the air deflector and / or the indoor fan returns to a normal state, that is, the air deflector returns to a set position and / or the indoor fan returns to a set rotating speed.

[0073] During the process that the compressor of the air conditioner stops or stops due to malfunction when the indoor temperature reaches the set temperature, the air conditioner will not produce odor after the indoor heat exchanger tube temperature decreases to a certain temperature and / or the compressor operates for a certain time after the operation of the damper is controlled to the preset odor prevention position and / or the indoor fan is controlled to operate at the preset minimum speed.

[0074] For example, when the indoor heat exchanger tube temperature is less than or equal to 18℃ or the compressor operating time reaches 8 minutes, the damper and / or the indoor fan speed returns to the normal state, that is, the damper returns to the set position and / or the indoor fan returns to the set speed.

[0079] Accordingly, the application provides a scheme that prolongs the judgment time of the indoor temperature reaching the set temperature, thereby delaying the shutdown time, reducing the number of shutdowns at the temperature point, and reducing the possibility of odor prevention.
