Detailed ways

In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

It should be noted that when the air conditioner is in heating operation, it takes a certain amount of time for the refrigerant to circulate when it is first turned on, especially when it has been left for too long, there will be no heating effect for a long time after it is turned on. At this time, if the indoor fan is turned on, it will blow out colder air, making people feel colder, but if it is not turned on, there will be no heat output.

Similarly, if the air conditioner filter or indoor heat exchanger is dirty and blocked, it is impossible to replace it in time. The above problems may also occur due to poor heat exchange.

In view of this, the present application provides a heating control method for an air conditioner. Specifically, FIG1 shows a flow chart of the heating control method for an air conditioner provided by the present application. As shown in FIG1 , the method includes:

S110, obtaining the coil temperature of the indoor fan in the heating mode of the air conditioner;

S120, generating a heating control instruction according to the coil temperature;

S130, controlling the wind speed of the indoor fan and the position of the air guide plate according to the heating control instruction.

It is understandable that in order to ensure that the air blown out by the indoor fan in the heating mode of the air conditioner is not cold air, the coil temperature of the indoor fan can be monitored in real time.

The coil temperature of the indoor fan in the heating mode of the air conditioner can be obtained through a temperature sensing package or a temperature sensor set on the coil. After obtaining the coil temperature of the indoor fan at the current moment, the heating control instruction corresponding to the coil temperature is generated according to the coil temperature range in which the coil temperature is located or whether it reaches a preset temperature threshold.

The heating control instruction refers to the adjustment instruction for the indoor fan and the air guide plate position at the current coil temperature. Specifically, it can be the wind speed gear of the indoor fan, and the direction and angle of the air guide plate. No specific limitation is made here.

In a specific embodiment, the obtained coil temperature of the indoor fan is compared with the current indoor ambient temperature. If it is determined that the coil temperature of the indoor fan is higher than the current indoor ambient temperature, the indoor fan is turned on and runs at a preset wind speed. If it is determined that the coil temperature of the indoor fan is not higher than the current indoor ambient temperature, the indoor fan is stopped or not turned on. At this time, the coil temperature can be adjusted by adjusting other components in the air conditioner to make it higher than the current indoor ambient temperature, thereby further controlling and adjusting the indoor fan.

In another specific embodiment, when the coil temperature has not reached the target temperature, the air guide plate is positioned to blow air upwards. When and only when the coil temperature reaches the target temperature, the air guide plate is adjusted to blow air downwards. At this time, the air can be blown onto the user in time without making the user feel cold.

On the basis of generating the heating control instruction according to the coil temperature in step S120, the air conditioner is controlled to execute the heating control instruction, that is, the air conditioner is controlled to adjust the wind speed of the indoor fan and the position of the air guide plate.

It should be noted that the application scenario of the embodiment of the present application is that the air conditioner operates in heating mode.

In this embodiment, by obtaining the coil temperature of the indoor fan in the heating mode of the air conditioner, a heating control instruction is generated according to the coil temperature, and the wind speed of the indoor fan and the position of the air guide plate are controlled and adjusted according to the heating control instruction. This method determines the start and stop, wind speed and air guide plate position of the indoor fan based on the coil temperature of the indoor fan, which can effectively ensure that the wind blown by the indoor fan is not cold wind, overcomes the defect of the existing air conditioner blowing cold wind during heating operation, and effectively improves the user's experience while meeting the user's heating needs.

On the basis of the above embodiment, further, according to the coil temperature, a corresponding heating control instruction is generated, including: obtaining the correspondence between the pre-stored coil temperature range and the preset control instruction; matching the coil temperature range in which the coil temperature is located; based on the correspondence, determining the preset control instruction corresponding to the coil temperature; wherein the heating control instruction is the preset control instruction corresponding to the coil temperature.

It can be understood that the heating control instruction is generated according to the coil temperature. Specifically, the air conditioner pre-stores the correspondence between the coil temperature range and the preset control instruction. That is to say, as long as the coil temperature range corresponding to the coil temperature of the indoor fan is determined, the corresponding preset control instruction can be determined. At this time, the preset control instruction is the heating control instruction.

Obtain the correspondence between the pre-stored coil temperature range and the preset control instruction, and determine the coil temperature range to which the coil temperature belongs based on the obtained coil temperature of the indoor fan. Thus, based on the pre-stored correspondence, the preset control instruction corresponding to the coil temperature range to which the coil temperature belongs can be determined, and the preset control instruction is the heating control instruction corresponding to the coil temperature.

In one example, based on the corresponding relationship, determining a preset control instruction corresponding to the coil temperature includes: determining that the coil temperature is lower than a first temperature threshold, the indoor fan is not running, and the air guide plate is in an upward blowing position.

It is understandable that when the coil temperature is lower than the first temperature threshold, the first temperature threshold is lower than the current indoor temperature. If the indoor fan is started, the air temperature blown out is lower than the current indoor temperature. The temperature will not only not make indoor users feel warm, but also make them feel colder. Therefore, in this case, the indoor fan will not run, and the air guide plate will be in a healthy upward blowing position to prevent cold wind from blowing people.

The first temperature threshold can be set according to the indoor temperature or the temperature set by the user, and is not specifically limited here.

For example, in a specific embodiment, the first temperature threshold is 25 degrees Celsius. When the coil temperature is lower than 25 degrees Celsius, the indoor fan that is running will stop running, and the indoor fan that is not running will not start. That is, the indoor fan is not running at this time, and the air guide plate position is a healthy upward blowing position.

In the second example, based on the corresponding relationship, the preset control instructions corresponding to the coil temperature are determined, including: determining that the coil temperature is higher than the first temperature threshold and lower than the second temperature threshold, the indoor fan is turned on the first wind speed gear, and the air guide plate is in the upward blowing position.

It is understandable that when the coil temperature is higher than the first temperature threshold and lower than the second temperature threshold, the coil temperature is not lower than the current indoor temperature, but not much higher. Therefore, in this case, the indoor fan will be turned on and the indoor fan will be controlled to run at the first wind speed gear, and the air guide plate position is still in the upward blowing position.

The second temperature threshold can be set according to the indoor temperature or the temperature set by the user, and is not specifically limited here.

For example, in a specific embodiment, the second temperature threshold is 32 degrees Celsius. When the coil temperature is between 25 degrees Celsius and 32 degrees Celsius, the indoor fan is controlled to operate at a lower wind speed, that is, to operate at the first wind speed gear, and the air guide plate position is still a healthy upward blowing position.

In the third example, based on the corresponding relationship, the preset control instruction corresponding to the coil temperature is determined, including: determining that the coil temperature is higher than the second temperature threshold and lower than the third temperature threshold, the indoor fan is turned on the second wind speed gear, and the air guide plate is in the upward blowing position.

It is understandable that when the coil temperature is higher than the second temperature threshold and lower than the third temperature threshold, the coil temperature will be much higher than the current indoor temperature. Therefore, increasing the wind speed of the indoor fan at this time can increase the overall indoor temperature to meet the user's heating needs.

The third temperature threshold can be set according to the indoor temperature or the user-set temperature, which is not specifically limited here.

For example, in a specific embodiment, the third temperature threshold is 34 degrees Celsius. When the coil temperature is between 32 degrees Celsius and 34 degrees Celsius, the indoor fan is controlled to run at a higher wind speed, that is, to run at the second wind speed gear, and the air guide plate position is still a healthy upward blowing position.

In the fourth example, based on the corresponding relationship, the preset control instructions corresponding to the coil temperature are determined, including: determining that the coil temperature is higher than the third temperature threshold, turning on the indoor fan to the highest wind speed gear, running at the user-set wind speed after the set running time, and the air guide plate position is the downward blowing position.

It is understandable that when the coil temperature is higher than the third temperature threshold, it means that the coil temperature is already much higher than the current indoor temperature, and there is no possibility that the user will feel cold. Therefore, the indoor fan is controlled to open the highest wind speed gear at this time to make the overall indoor temperature rise quickly. At this time, the air guide plate is in the upward blowing position.

After the indoor fan runs at the highest wind speed for a set period of time, the indoor fan is controlled to run at the wind speed set by the user. At this time, hot air can be blown onto the user, and the air guide plate is in the downward blowing position.

In a specific embodiment, when the coil temperature is higher than 34 degrees Celsius, the indoor fan runs at the highest wind speed for 10 minutes to first increase the overall indoor temperature, and then runs at the wind speed set by the user, with the air guide plate in the heating down-blowing position.

It should be noted that before the indoor fan in the control room runs at the wind speed set by the user, the air guide plate is always in the healthy upward blowing position.

In this embodiment, by obtaining the correspondence between the pre-stored coil temperature range and the preset control instruction, the coil temperature range in which the coil temperature is located is matched, and based on the correspondence, the preset control instruction corresponding to the coil temperature is determined, that is, the heating control instruction, so that according to the heating control instruction, the wind speed of the indoor fan and the position of the air guide plate are controlled and adjusted, which can effectively ensure that the wind blown by the indoor fan is not cold wind, overcomes the defect of the existing air conditioner blowing cold air during heating operation, and effectively improves the user's experience while meeting the user's heating needs.

On the basis of the above embodiment, the method further includes: determining that the duration of time that the coil temperature is in a single coil temperature range reaches a preset duration threshold; controlling the wind speed of the indoor fan to increase by one wind speed level for each preset duration threshold, and the position of the air guide plate is an upward blowing position.

It is understandable that the obtained coil temperature of the indoor fan may be in any pre-stored coil temperature range. When the coil temperature is in a certain coil temperature range for a preset time, In the case of a threshold, the heating control command corresponding to the current coil temperature range is first operated. After maintaining the preset time threshold, the indoor fan is controlled to increase one wind speed gear and the air guide plate position is always in the upward blowing position.

The preset time threshold can be set according to the indoor heating situation and is not specifically limited here. For example, in a specific embodiment, the preset time threshold is 4 minutes, and after the indoor fan runs at the first wind speed gear for 4 minutes, it automatically enters the state of running at the second wind speed gear, and so on.

Further, it is determined that the wind speed gear of the indoor fan reaches the maximum wind speed gear, and the indoor fan is controlled to run according to the wind speed set by the user, and the position of the air guide plate is the downward blowing position.

In this embodiment, by determining that the time duration that the coil temperature is in a single coil temperature range reaches a preset time threshold, the wind speed of the indoor fan is controlled to increase by one wind speed level at every preset time threshold, and the air guide plate position is an upward blowing position until the wind speed level of the indoor fan increases to the highest wind speed level. The indoor fan is then controlled to operate at the wind speed set by the user. At this time, the air guide plate position is a downward blowing position, which can effectively ensure that the wind blown out by the indoor fan is not cold wind, thereby effectively improving the user experience.

On the basis of the above embodiment, further, it is determined that the coil temperature is lower than the first temperature threshold, and then includes: increasing the compressor operating frequency to a preset compressor frequency, and increasing the expansion valve opening to a preset valve opening; determining that the coil temperature reaches the user-set temperature, and controlling the compressor and expansion valve of the air conditioner to operate according to the default values respectively.

It is understandable that, when it is determined that the coil temperature is lower than the first temperature threshold, the coil temperature can be adjusted by adjusting other components in the air conditioner, wherein the other components in the air conditioner include but are not limited to a compressor and an electronic expansion valve.

Specifically, the coil temperature of the outdoor fan can be increased by increasing the compressor frequency and increasing the expansion valve opening, increasing the compressor operating frequency to a preset compressor frequency, and increasing the expansion valve opening to a preset valve opening until the coil temperature reaches the user-set temperature. The operating modes of the compressor and expansion valve of the air conditioner can be adjusted again, for example, controlling the compressor and expansion valve of the air conditioner to operate according to the default values.

In this embodiment, when it is determined that the coil temperature is lower than the first temperature threshold, the compressor operating frequency is increased to a preset compressor frequency, and the expansion valve opening is increased to a preset valve opening. When the coil temperature reaches the user-set temperature, the compressor and expansion valve of the air conditioner are controlled separately. It runs at the default value and can quickly meet the user's heating needs when the coil temperature is low, improving the user experience.

On the basis of the above embodiment, further, when it is determined that the temperature set by the user exceeds the temperature limit, the air conditioner is controlled to send a voice confirmation prompt to the user; according to the user's confirmation result, the air conditioner is controlled to operate according to the temperature set by the user.

It is understandable that when a user has a heating demand, he can manually input the set temperature value he wants to reach indoors through the remote control or voice input, that is, the user-set temperature. At this time, there is a situation that the temperature value set by the user is not necessarily the optimal temperature value. The optimal temperature value here refers to the temperature that is most comfortable for the human body calculated by the air conditioner based on the current indoor temperature and the outdoor ambient temperature.

When the user-set value exceeds the temperature range that makes the human body feel comfortable, the air conditioner will send a voice confirmation prompt to the user. If the user insists on confirming the user-set value, the air conditioner will be controlled to operate according to the user-set temperature based on the confirmation result input by the user through voice.

It should be noted that if the user does not confirm within the first set time period, or determines not to control the air conditioner to operate at the user-set temperature, the air conditioner will automatically operate at the calculated optimal temperature value.

It should also be noted that the temperature limit is the optimal temperature value, and the user's confirmation result is that the user confirms that the air conditioner is running at the temperature value set by the user.

In this embodiment, by determining that the temperature set by the user exceeds the temperature limit, the air conditioner is controlled to send a voice confirmation prompt to the user, and the air conditioner is controlled to operate according to the user set temperature based on the confirmation result. This can take the user's thermal comfort into consideration and enhance the user's experience.

On the basis of the above embodiments, the method further includes: obtaining personnel monitoring information within the blowing range of the air conditioner, the personnel monitoring information including user appearance information, location information, body temperature information and medical history information; according to the personnel monitoring information, controlling the wind speed of the indoor fan and the blowing angle of the air guide plate.

It is understandable that, on the basis of ensuring that the indoor fan does not blow cold air, if the air guide plate is always blowing towards the user, even if it is hot air, it will make the user feel uncomfortable, especially for some special groups of people, such as infants, the elderly and some patients with corresponding diseases, who cannot stand the direct blowing of hot air.

Considering this, the user's appearance information, location information, and body The system senses temperature information and medical history information, and based on this series of information, determines whether the target person belongs to a special population, and adjusts the wind speed of the indoor fan and the blowing angle of the air guide plate based on the judgment result.

It can be understood that based on the appearance information of the target object, the height and age of the object can be known, so as to determine whether the object is an elderly person, a child or a pregnant woman; based on the location information of the target object, the distance between the object and the air guide plate can be determined; based on the body temperature information of the target object, it can be known whether the body temperature of the object is normal, and when the object has a fever, the air conditioner can be controlled in time to sound an alarm to achieve the purpose of reminder; based on the medical history information of the target object, the particularity of the object can be known, and the air guide plate can be controlled not to directly supply air to it.

Among them, the user's appearance information and location information can be obtained through a camera. The camera can be installed at a higher place than the air conditioner, such as at the display panel. Of course, it can also be other locations in the room that are suitable for obtaining the aforementioned information, which is not specifically limited here.

The body temperature information can be obtained through the temperature sensor, and the medical history information can be pre-entered and stored, and can be called up according to the user's identity information when needed.

In this embodiment, by obtaining personnel monitoring information within the blowing range of the air conditioner, and controlling the wind speed of the indoor fan and the blowing angle of the air guide plate according to the personnel monitoring information, when the indoor users are special groups of people, the indoor fan is controlled to reduce the wind speed gear and the blowing angle of the air guide plate is controlled so that it does not directly supply air to the user's position, which can effectively improve the user experience.

In addition, FIG. 2 shows a control schematic diagram of the heating control method of the air conditioner provided in the present application.

As shown in Figure 2, the horizontal axis is the wind speed level of the indoor fan. Weak corresponds to the first wind speed level of the indoor fan, low corresponds to the second wind speed level of the indoor fan, and set corresponds to the maximum wind speed level of the indoor fan and the user-set wind speed.

The vertical axis is the heat exchange temperature, that is, the coil temperature, which can also be understood as the coil temperature range where the coil temperature is located, including the first temperature threshold of 25 degrees Celsius, the second temperature threshold of 32 degrees Celsius, the third temperature threshold of 34 degrees Celsius and the lowest temperature value of 23 degrees Celsius.

According to FIG. 2 , it can be seen that between the wind speed level of the indoor fan and the coil temperature, the higher the coil temperature, the higher the wind speed level of the indoor fan, and vice versa, the lower the wind speed level of the indoor fan.

It can also be seen from Figure 2 that when the indoor fan runs at a certain wind speed level for a preset time threshold After 4 minutes, the fan will automatically increase one speed level and continue to run.

Fig. 3 shows a schematic diagram of the structure of the heating control device of the air conditioner provided in the present application. As shown in Fig. 3, the device includes: a temperature acquisition module 310, which is used to acquire the coil temperature of the indoor fan in the heating mode of the air conditioner; an instruction generation module 320, which is used to generate a heating control instruction according to the coil temperature; and a heating control module 330, which is used to control the wind speed of the indoor fan and the position of the air guide plate according to the heating control instruction.

In this embodiment, the temperature acquisition module 310 acquires the coil temperature of the indoor fan in the heating mode of the air conditioner, and the instruction generation module 320 generates a heating control instruction according to the coil temperature, so that the heating control module 330 controls and adjusts the wind speed of the indoor fan and the position of the air guide plate according to the heating control instruction. The device determines the start and stop, wind speed and air guide plate position of the indoor fan based on the coil temperature of the indoor fan, which can effectively ensure that the wind blown by the indoor fan is not cold wind, overcomes the defect of the existing air conditioner blowing cold wind during heating operation, and effectively improves the user's experience while meeting the user's heating needs.
