Fig. 1 is a schematic structural diagram of an air conditioner according to an embodiment of the present disclosure. As shown in fig. 1, the air conditioner includes a base, a first casing 100, and a second casing 200. The first housing is provided with a first air outlet 110, a first fan 120 is disposed inside the first housing, and the first air outlet 110 is further provided with a first air deflector 111. The second casing 200 is provided with a second air outlet 210, and a second fan 220 is disposed inside the second casing, wherein a second air deflector 211 is disposed on the second air outlet 210. A circulation air duct for guiding air is formed between the first casing 100 and the second casing 200, and the first air outlet 110 and the second air outlet 210 are arranged oppositely, that is, the circulation air duct for guiding air is located between the first air outlet 110 and the second air outlet 210. When the first fan 120 and the second fan 220 rotate, negative pressure is generated in the ventilation duct for guiding the air, so that the air outside the first casing 100 and the second casing 200 can enter the ventilation duct and flow out of the ventilation duct together with the air flow blown out from the first air outlet 110 and the air flow blown out from the second air outlet 210. That is, under the condition that the first fan 120 and the second fan 220 operate, no airflow in the indoor environment directly exchanges heat with the air conditioner heat exchanger can flow into the ventilation duct under the action of the negative pressure generated in the ventilation duct, and this part of airflow flowing into the ventilation duct is the induced airflow. The induced air is mixed with the air flow blown out from the first air outlet 110 and the second air outlet 210 to form mixed air with proper temperature, and then the mixed air is sent out of the circulation air duct together, so that the air supply comfort of the air conditioner can be improved.
Alternatively, the direction of the airflow blown out from the first air outlet 110 can be changed by changing the opening angle of the first air deflector 111; alternatively, the direction of the airflow blown out from the second outlet 210 is changed by changing the opening angle of the second air deflector 211. Alternatively, the opening angle of the first air deflector 111 and the opening angle of the second air deflector 211 may be changed simultaneously, so as to change the direction of the airflow blown out from the first outlet 110 and the direction of the airflow blown out from the second outlet 210.
Alternatively, the first and second housings 100 and 200 may be rotatably provided on the base. In this way, the direction of the airflow blown out by the first air outlet 110 can be changed by controlling the first air outlet 110 on the first casing 100 to rotate in a direction away from the second casing 200; alternatively, the direction of the airflow blown out by the second air outlet 210 can be changed by controlling the second air outlet 210 on the second casing 200 to rotate in a direction away from the first casing 100. For example, the first housing 100 is disposed on the left side of the second housing 200, and when the air conditioner is in the power-off state, the first outlet 110 and the second outlet 210 are in opposite positions, that is, the first outlet 110 faces the second outlet 210, and the second outlet 210 faces the first outlet 110. In practical use, the first casing 100 can be controlled to rotate to the left relative to the base, that is, the first outlet 110 can rotate to the left relative to the second casing 200/the second outlet 210, so that the direction of the airflow blown out by the first outlet 110 can be changed; alternatively, the second housing 200 may be controlled to rotate rightward relative to the base, that is, the second outlet 210 may rotate rightward relative to the first housing 100/the first outlet 110, so as to change the direction of the airflow blown out from the second outlet 210. Alternatively, the first casing 100 may be controlled to rotate left relative to the base, and the second casing 200 may be controlled to rotate right relative to the base, that is, the first outlet 110 may rotate left relative to the second casing 200/the second outlet 210 while the second outlet 210 rotates right relative to the first casing 100/the first outlet 110, so as to change the direction of the airflow blown out by the first outlet 110 and change the direction of the airflow blown out by the second outlet 210.
Optionally, after the air conditioner is turned on and operated, the air outlet angles of the first air outlet 110 and the second air outlet 210 are the same, so as to ensure uniformity of the air outlet flows of the first air outlet 110 and the second air outlet 210.
In practical applications, when a user turns on the air conditioner, a temperature is usually set as a target operation temperature of the air conditioner, so that the indoor ambient temperature can be adjusted to be comfortable for the user. However, in the process of starting the air conditioner, the drainage air may flow backward into the air conditioner along the first air outlet and/or the second air outlet, and the drainage air may entrain impurities such as particulate matters and debris to enter the air conditioner, and the impurities may be sucked into the first fan and/or the second fan to cause sudden stop of the first fan and/or the second fan.
Accordingly, the present disclosure provides an air conditioner control scheme, which helps to prevent the drainage air from flowing backward into the first air outlet and/or the second air outlet, thereby improving the safety of the air conditioner and prolonging the service life of the air conditioner. Specifically, when the air conditioner is started, the target operation temperature of the air conditioner and the ambient temperature of the space where the air conditioner is located can be obtained, and when the difference value between the target operation temperature of the air conditioner and the ambient temperature of the space where the air conditioner is located is larger than a first preset difference value, the first air outlet and the second air outlet are controlled to execute a first control instruction for increasing the flow rate of the drainage air.
Optionally, the first air outlet 110 and the second air outlet 210 are provided with filter screens 300. Like this, in practical application, in case the condition that the drainage wind flows backward along first air outlet 110 and/or second air outlet 210 and gets into the inside of air conditioner, can wrap up impurity separation such as particulate matter, piece in the drainage wind through the filter screen 300 that sets up and carry outside the air conditioner, prevent that these impurity from being inhaled to first fan 120 and/or in the second fan 220 to guarantee the normal operating of air conditioner, improve the life of air conditioner.
Fig. 2 is a schematic diagram of a control method for an air conditioner according to an embodiment of the present disclosure. With reference to fig. 2, an embodiment of the present disclosure provides a control method for an air conditioner, where the air conditioner includes a first housing with a first air outlet and a second housing with a second air outlet, the first air outlet and the second air outlet are arranged oppositely, and a circulation air duct for guiding air is formed between the first air outlet and the second air outlet, and the control method includes:
and S11, receiving a starting instruction, and acquiring the target operating temperature of the air conditioner and the ambient temperature of the space where the air conditioner is located.
And S12, when the difference between the target operation temperature of the air conditioner and the environment temperature of the space where the air conditioner is located is larger than a first preset difference, controlling the first air outlet and the second air outlet to execute a first control instruction for increasing the flow rate of the drainage air.
In step 11, after the air conditioner receives a power-on instruction from a user, a target operating temperature of the air conditioner and an ambient temperature of a space where the air conditioner is located are detected and obtained, so that an operating state after power-on is determined conveniently.
In the scheme, a user can issue the starting-up instruction through the remote control equipment matched with the air conditioner.
In one example, a smart voice device may also be provided on the air conditioner. Specifically, the smart voice device may be a smart speaker, a smart microphone, or the like, that is, a device having a voice system and capable of being disposed on an air conditioner. And when the intelligent voice equipment detects that the voice information of the user contains a starting instruction, controlling the air conditioner to start. Therefore, the air conditioner is started through voice control, the air conditioner can be started at any time, and the time for searching the remote control equipment and operating the remote control equipment is saved.
In another example, a human sensing device may be provided in an air conditioner. Specifically, the human motion sensing device may be an infrared sensor or an image sensor, and the type of the human motion sensing device in the embodiment of the present disclosure is not particularly limited. The air conditioner can be controlled to be started when the human sensing device detects that the user is present in the sensing area. The air conditioner can be controlled to be started under the condition that the human sensing device detects that the user is present in the sensing area and stays for a period of time. Therefore, the air conditioner can be automatically started at a proper time by setting the trigger condition for starting the air conditioner, and the intelligence of the air conditioner is improved.
In this scheme, the obtained target operating temperature of the air conditioner may be a temperature that is set by a user when the air conditioner is started. Or different starting target operation temperatures set by different operation modes corresponding to manufacturers when the air conditioner leaves the factory, for example, the manufacturers set the target operation temperature after starting up in the cooling mode to be 21 ℃ and the target operation temperature after starting up in the heating mode to be 26 ℃ according to the relevant national standards of the air conditioner. The temperature can also be automatically set by the air conditioner according to the use habits of the user, for example, the air conditioner can collect the set temperature of the user after the user starts up in the last 15 days, and automatically set the temperature according to the operation mode selected by the user after classification and analysis according to different operation modes. Specifically, if the user selects the heating mode, the air conditioner will extract all the user-set startup target operating temperatures in the heating mode within the last 15 days. The air conditioner may use a temperature value set by a user the most frequently as an automatically set temperature, or may use an average value of the start-up target operation temperatures of all the set heating modes as an automatically set temperature. Therefore, the target operation temperature of the air conditioner during starting can be set, the air conditioner can provide the appropriate target temperature for the user, and the convenience of the air conditioner is improved.
In this scheme, a temperature detection device may be disposed on the air conditioner for detecting an ambient temperature of a space where the air conditioner is located, and specifically, the temperature detection device may be a temperature sensor. In some examples, the air conditioner can also communicate with an electronic thermometer in the space where the air conditioner is located, so that the temperature in the room detected by the electronic thermometer is obtained, and the cost of the air conditioner is further reduced. Alternatively, the electronic thermometer may be a small independent household appliance, or may be disposed on another household appliance. Therefore, the linkage of the air conditioner and other household appliances can be realized, and the intellectualization of the household appliances is improved.
In step 12, when the difference between the target operating temperature of the air conditioner and the ambient temperature of the space where the air conditioner is located is greater than a first preset difference, the first air outlet and the second air outlet are controlled to execute a first control instruction for increasing the flow rate of the guide air.
In the scheme, according to the fact that the difference value between the target operation temperature of the air conditioner and the environment temperature of the space where the air conditioner is located is larger than the first preset difference value, the air supply quantity of the air conditioner for adjusting the temperature can be determined, and therefore the air flow direction of the air flowing out of the first air outlet and the second air outlet and the air quantity of the drainage air are adjusted. In one example, the first preset temperature may be set to 2 ℃.
In an example, after the processor of the air conditioner receives the start-up instruction, the first air deflector on the first air outlet is controlled to change the opening angle, or the second air deflector on the second air outlet is controlled to change the opening angle, or the first air deflector on the first air outlet and the second air deflector on the second air outlet are controlled to simultaneously change the opening angle, so that the air outlet direction of the air flow of the first air outlet and/or the second air outlet is changed, that is, an included angle or parallelism is formed between the air outlet directions of the air flow of the first air outlet and the air flow of the second air outlet, so that the air volume of the flow guiding air is increased, the possibility that the flow guiding air flows into the first shell or the second shell is reduced, and the safety and the service life of the air conditioner are improved.
In another example, after the processor of the air conditioner receives the start-up instruction, the processor of the air conditioner may control the first housing to rotate or control the second housing to rotate, or control the first housing and the second housing to rotate, so as to change the orientations of the first air outlet and the second air outlet, and further enable the air outlet directions of the air flows of the first air outlet and the second air outlet to have an included angle or be parallel, thereby increasing the air volume of the flow-guiding air, reducing the possibility that the flow-guiding air flows into the first housing or the second housing, and improving the safety and the service life of the air conditioner. The mode of changing the air outlet direction of the airflow at the first air outlet and/or the second air outlet is set, so that various air conditioner air outlet adjusting modes are realized.
By adopting the control method for the air conditioner provided by the embodiment of the disclosure, when the air conditioner is started, under the condition that the difference between the target operation temperature of the air conditioner and the environment temperature of the space where the air conditioner is located is greater than a first preset difference, the first air outlet and the second air outlet are controlled to execute the first control instruction for increasing the air volume of the drainage air, and the air outlet direction of the air flow of the first air outlet and the second air outlet can be changed, so that the circulation air channel of the drainage air can be enlarged during the starting operation, the air volume of the drainage air can be increased, the drainage air is prevented from flowing backwards into the first air outlet and/or the second air outlet, the safety of the air conditioner is improved, and the service life of the air conditioner.
Optionally, in order to increase the flow rate of the flow-guiding air, when the difference between the target operating temperature of the air conditioner and the ambient temperature of the space where the air conditioner is located is greater than a first preset difference and smaller than a second preset difference, that is, when the difference between the target operating temperature of the air conditioner and the ambient temperature of the space where the air conditioner is located is between the first preset difference and the second preset difference, in order to reduce energy consumption and temperature adjustment time of the air conditioner, it is necessary to provide a large flow rate for rapid temperature adjustment for the environment where the air conditioner is located, at this time, the direction of the flow blown out from the first air outlet and/or the direction of the flow blown out from the second air outlet are adjusted according to the first control instruction, so that the direction of the flow blown out from the first air outlet and the direction of the flow blown out from the second air outlet intersect to form an acute angle, thereby enlarging a negative pressure area forming the flow-guiding air, to reduce the flow of induced wind into the first housing and/or the second housing. Or when the difference between the target operation temperature of the air conditioner and the ambient temperature of the space where the air conditioner is located is not less than a second preset difference, that is, when the difference between the target operation temperature of the air conditioner and the ambient temperature of the space where the air conditioner is located is relatively large, in order to further realize rapid temperature adjustment, a larger air volume needs to be provided, at this time, the direction of the airflow blown out by the first air outlet is adjusted and/or the direction of the airflow blown out by the second air outlet is adjusted according to the first control instruction, so that the direction of the airflow blown out by the first air outlet is parallel to and consistent with the direction of the airflow blown out by the second air outlet, and the negative pressure area forming the ventilation duct is further expanded, thereby maximizing the air volume of the drainage air, so as to match the air flows blown out by the first air outlet and the second air outlet to form mixed air with appropriate temperature in the ventilation duct, and reduce the flow of the, and the air supply fluidity of the air conditioner is improved while the temperature can be further quickly adjusted, so that the indoor temperature is quickly and uniformly adjusted and is comfortable. In one example, the second preset difference may be set to 5 ℃.
