Description

Technical Field

[0001] This application relates to the field of air conditioning, and more particularly to an air conditioner and its control method, apparatus, storage medium and product. Background Technology

[0002] Floor-standing air conditioners typically only have air outlets at the top of the casing. When the air conditioner is in heating mode, the hot air blown out by the air conditioner cannot be directly blown to the user because the air outlet is positioned high. In related technologies, some floor-standing air conditioners have air outlets at both the top and bottom of the casing. When the air conditioner is in heating mode, the hot air blown out by the bottom air outlet can be directly blown to the user.

[0003] However, in practical applications, it has been found that when an air conditioner with a bottom air outlet is running in heating mode, if the actual heating capacity of the air conditioner is insufficient, the user will feel a significant coldness, which will affect the user's airflow experience.

[0025] In some implementations, the method further includes:

[0026] When the lower air outlet assembly is in the open state, the opening angle of the lower air outlet assembly is controlled based on the temperature value of the indoor heat exchanger.

[0027] In some implementations, controlling the opening angle of the lower air outlet assembly based on the indoor heat exchanger temperature includes:

[0028] If it is determined that the indoor heat exchanger temperature is greater than the fourth temperature threshold, then the lower air outlet assembly is controlled to open to the first angle.

[0053] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0055] This application provides a control method for an air conditioner. The upper part of the air conditioner's casing is provided with an upper air outlet and an upper air outlet assembly, and the lower part of the casing is provided with a lower air outlet and a lower air outlet assembly. Figure 1 As shown, the method includes:

[0056] Step 101: In heating mode, obtain the indoor temperature value and the indoor heat exchanger temperature value.

[0057] Step 102: Based on the indoor temperature value and / or the indoor heat exchanger temperature value, control the lower air outlet assembly to open.

[0058] This air conditioner is used to regulate the temperature and humidity of the environment. It can be a dual-function air conditioner (cooling and heating) and can be a floor-standing unit.

[0059] Here, in some embodiments, the structure of the air conditioner is as follows: Figures 2A to 2C As shown. The outer casing 100 of the air conditioner is provided with an upper air outlet 200 and a lower air outlet 300. An upper air outlet assembly 400 is provided on the upper air outlet 200, and a lower air outlet assembly 500 is provided on the lower air outlet 300. When the air conditioner is running, after the upper air outlet assembly 400 is opened, the air conditioner blows air from the upper air outlet 200, and after the lower air outlet assembly 500 is opened, the air conditioner blows air from the lower air outlet 300.

[0060] For example, the method further includes: controlling the upper air outlet assembly to open in response to a heating mode command.

[0061] Here, in this embodiment of the application, in response to the heating mode command, the air conditioner enters the heating mode and controls the upper air outlet assembly to open. At this time, the lower air outlet assembly is in the closed state, that is, the lower air outlet of the air conditioner will not blow air.

[0062] Here, the heating mode command can be a control command actively sent by the user or a control command generated internally by the air conditioner. For example, the air conditioner generates a heating mode command based on exiting the defrost mode, and the air conditioner responds to the heating mode command and resumes operation in heating mode.

[0063] It is understood that when the air conditioner in this application embodiment is running in heating mode, the upper air outlet is opened first, and the lower air outlet is opened according to the current indoor temperature value and / or the indoor heat exchanger temperature value. This avoids the problem that when the actual heating capacity of the air conditioner is insufficient, the lower air outlet will blow cold air directly to the user, resulting in a noticeable cold feeling for the user, thus improving the user's airflow experience.

[0064] For example, the method further includes: after entering the heating mode, controlling the air conditioner to perform the anti-cold air function within a first set time period.

[0065] For example, controlling the air conditioner to perform the anti-cold air function within a first set time period includes: controlling the air conditioner's fan speed based on the indoor heat exchanger temperature value within the first set time period.

[0066] It should be noted that when the air conditioner is in heating mode, the compressor has not yet started or the actual heating capacity of the air conditioner cannot meet the mode requirements. The air temperature after being heated by the indoor heat exchanger is low. Therefore, the air conditioner usually performs the anti-cold air function by controlling the air conditioner's fan speed to prevent cold air from blowing into the room.

[0067] In one application example of this application, the air conditioner is set to a set temperature value T1. After the air conditioner activates the anti-cold air function, it includes two fan speed modes: a set fan speed and a low fan speed. If the indoor heat exchanger temperature value is greater than or equal to the set temperature value T1, the air conditioner operates at the set fan speed; if the indoor heat exchanger temperature value is less than the set temperature value T1, the air conditioner operates at the low fan speed.

[0068] In this example, the temperature value T1 can be set to 30℃.

[0069] In another application example of this application, after the air conditioner activates its anti-cold air function, the relationship between the air conditioner's fan speed and the indoor heat exchanger temperature is as follows: Figure 3 As shown, the air conditioner is set with four temperature settings from high to low: TEL5, TEL4, TEL3, and TEL2. The fan speed is adjusted based on the comparison between the current indoor heat exchanger temperature and each set temperature value.

[0070] Specifically, after the air conditioner activates the anti-cold air function, it includes two fan speed modes: a set fan speed and a low fan speed. If the indoor heat exchanger temperature rises to the set temperature value TEL4, the indoor fan will start and the air conditioner will operate at the low fan speed. If the indoor heat exchanger temperature rises to the set temperature value TEL5, the air conditioner will switch from the low fan speed to the set fan speed. If the indoor heat exchanger temperature drops to the set temperature value TEL3, the air conditioner will switch from the set fan speed to the low fan speed. If the indoor heat exchanger temperature drops to the set temperature value TEL2, the indoor fan will stop.

[0071] For example, the method further includes: after the air conditioner has been running in heating mode for a first set time, controlling the air conditioner to exit the anti-cold air function.

[0072] Here, after the air conditioner deactivates the anti-cold air function, it switches to normal heating function and operates at the set fan speed.

[0073] Understandably, during the first set time period, when the air conditioner is using the anti-cold air function, if the indoor heat exchanger temperature is low, the air conditioner's fan speed will be reduced to prevent the air conditioner from blowing cold air into the room due to excessive fan speed.

[0074] In one application example of this application, the first set duration is 5 minutes.

[0075] For example, controlling the lower air outlet assembly to open based on the indoor temperature value and / or the indoor heat exchanger temperature value includes: after deactivating the anti-cold air function, controlling the lower air outlet assembly to open based on the indoor temperature value and / or the indoor heat exchanger temperature value.

[0076] It should be noted that when the air conditioner is in anti-cold air function mode, the lower air outlet assembly is in the closed state; after the air conditioner switches to normal heating function, it controls the lower air outlet assembly to open based on the indoor temperature value and / or the indoor heat exchanger temperature value.

[0077] It is understandable that, within the first set time period, the actual heating capacity of the air conditioner may not meet the mode requirements. Even if the air conditioner is running at the low fan speed, the air outlet temperature may still be low. Therefore, in this embodiment of the application, when the air conditioner performs the anti-cold air function, it only blows air out through the upper air outlet, avoiding the problem that when the indoor temperature is low, the low-temperature airflow blows directly to the user through the lower air outlet, causing the user to feel a significant cold air sensation.

[0078] For example, controlling the lower air outlet assembly to open based on the indoor temperature value and / or the indoor heat exchanger temperature value further includes: after deactivating the anti-cold air function, controlling the lower air outlet assembly to open within a second set time period based on the indoor temperature value reaching a first temperature threshold.

[0079] Understandably, when the indoor temperature reaches the first temperature threshold, the lower air outlet component is opened. Since the current indoor temperature is high, even if the air temperature from the lower air outlet is low, the user's feeling of coolness will not be obvious and will not affect the user's airflow experience.

[0080] In one application example of this application, the second set duration is 3 minutes, and the first temperature threshold is 20°C.

[0081] Understandably, after the air conditioner deactivates the anti-cold air function, if the indoor temperature is lower than the first temperature threshold within the second set time period, the lower air outlet component will be kept closed to prevent the indoor temperature and the air temperature from the lower air outlet from being too low when the lower air outlet component is opened, resulting in a noticeable cold feeling for the user.

[0082] For example, controlling the opening of the lower air outlet component based on the indoor temperature value and / or the indoor heat exchanger temperature value further includes: after the anti-cold air function has been deactivated for a second set time, controlling the opening of the lower air outlet component within a third set time period based on the indoor heat exchanger temperature value reaching a preset temperature threshold.

[0083] It is understandable that when the indoor temperature does not meet the aforementioned conditions for opening the lower air outlet component, in this embodiment of the application, if the current indoor heat exchanger temperature is high, the lower air outlet component is controlled to open, that is, the air outlet temperature is high. Even if the current indoor temperature is low, since the airflow directly blown to the user from the lower air outlet is hot air, it will not affect the user's airflow experience.

[0084] For example, the method further includes: determining whether the electric auxiliary heating module of the air conditioner is running within a third set time period.

[0085] For example, controlling the lower air outlet assembly to open based on the indoor heat exchanger temperature reaching a preset temperature threshold includes: if it is determined that the electric auxiliary heating module is in operation, then controlling the lower air outlet assembly to open based on the indoor heat exchanger temperature reaching a second temperature threshold; if it is determined that the electric auxiliary heating module is in shutdown state, then controlling the lower air outlet assembly to open based on the indoor heat exchanger temperature reaching a third temperature threshold; wherein the second temperature threshold is greater than the third temperature threshold.

[0086] It should be noted that the control method of the electric auxiliary heating module is not specifically limited in the embodiments of this application. The air conditioner can actively control the electric auxiliary heating module to start or stop according to the user's instructions, or it can control the electric auxiliary heating module to start or stop based on the indoor temperature value.

[0087] It is understandable that when the electric auxiliary heating module is running, the indoor heat exchanger temperature is high. After the electric auxiliary heating module stops, the indoor heat exchanger temperature drops, which in turn lowers the outlet air temperature. Therefore, in this embodiment, if the electric auxiliary heating module is running, the lower outlet component is controlled to open based on the indoor heat exchanger temperature reaching a higher third temperature threshold. This is to prevent the outlet air temperature from dropping rapidly after the electric auxiliary heating module stops, which would result in an excessively low outlet air temperature and cause the user to experience a noticeable cooling sensation.

[0088] In one application example of this application, the second temperature threshold is 35°C, the third temperature threshold is 40°C, and the second set duration is 2 minutes.

[0089] For example, the method further includes: after the anti-cold air function has been deactivated for a fourth set period of time, controlling the lower air outlet component to open.

[0090] The fourth setting duration is longer than the second setting duration.

[0091] It is understandable that after the air conditioner has exited the anti-cold air function for the fourth set time, even if the indoor heat exchanger temperature has not reached the corresponding temperature threshold, the air conditioner's heating capacity has already met the mode requirements. Therefore, opening the lower air outlet component will not affect the user's airflow experience.

[0092] In some embodiments, the fourth set duration is the sum of the second set duration and the third set duration; in one application example of this application, the fourth set duration is 5 minutes.

[0093] For example, the method further includes: when the lower air outlet assembly is in the open state, controlling the opening angle of the lower air outlet assembly based on the indoor heat exchanger temperature value.

[0094] Understandably, in order to further enhance the user's airflow experience, this application embodiment controls the opening angle of the lower air outlet assembly based on the indoor heat exchanger temperature value to adjust the airflow volume of the lower air outlet, and provides a method for controlling the opening angle of the lower air outlet assembly.

[0095] Specifically, based on the indoor heat exchanger temperature, the opening angle of the lower air outlet assembly is controlled, including:

[0096] If the indoor heat exchanger temperature is determined to be greater than the fourth temperature threshold, the lower air outlet assembly is controlled to open to the first angle; if the indoor heat exchanger temperature is determined to be greater than or equal to the fifth temperature threshold and less than the fourth temperature threshold, the lower air outlet assembly is controlled to open to the second angle; if the indoor heat exchanger temperature is determined to be less than the fifth temperature threshold, the lower air outlet assembly is controlled to open to the third angle. The first angle is greater than the second angle, and the second angle is greater than the third angle.

[0097] It is understandable that the higher the temperature of the indoor heat exchanger, the higher the temperature of the airflow directly blown towards the user from the lower air outlet. Therefore, increasing the opening angle of the lower air outlet to increase the air volume will not affect the user's airflow experience. Moreover, the increased air volume from the lower air outlet allows the hot air generated by the air conditioner to be blown directly towards the user as much as possible.

[0098] Here, in some embodiments, the first angle is the maximum opening angle of the lower air outlet assembly, the second angle is the middle opening angle of the lower air outlet assembly, and the third angle is the minimum opening angle of the lower air outlet assembly.

[0099] In one application example of this application, the fourth temperature threshold is 40°C and the fifth temperature threshold is 35°C.

[0100] In some embodiments, after the lower air outlet assembly is opened, the upper air outlet assembly remains open.

[0101] In some embodiments, the method further includes: after determining that the lower air outlet assembly is open, controlling the upper air outlet assembly to close.

[0102] Understandably, in heating mode, when the lower air outlet component is opened, the upper air outlet component is closed, so that the hot air generated by the air conditioner is blown directly to the user through the lower air outlet as much as possible.

[0103] For example, such as Figure 2A As shown, the air conditioner's outer casing has a left air outlet 600 and a right air outlet (not shown in the figure) on both sides. The air conditioner's interior also includes a vertical air guide assembly and a horizontal air guide assembly. The method further includes: after the upper air outlet assembly and / or the lower air outlet assembly are opened, controlling the vertical air guide assembly to open.

[0104] Here, the vertical air guide assembly is used to control the air outlet angle and air volume of the left air outlet 600 and the right air outlet. The hot air generated by the air conditioner is blown out from the upper air outlet and / or the lower air outlet, and is also blown into the room through the air outlets on both sides.

[0105] For example, the method further includes: after the lower air outlet assembly is opened, controlling the horizontal air guide assembly to face the lower air outlet.

[0106] Here, the horizontal air guide component is used to control the air volume of the upper and lower air outlets of the air conditioner. After the lower air outlet component is opened, the horizontal air guide component is controlled to be oriented towards the lower air outlet, so that the airflow generated by the indoor fan is heated by the indoor heat exchanger and blown directly to the user from the lower air outlet as much as possible, thereby increasing the air volume of the lower air outlet.

[0107] Understandably, when the lower air outlet component is closed and the upper air outlet component is open, controlling the horizontal air guide component to point towards the upper air outlet can increase the air volume of the upper air outlet.

[0108] In one application example of this application, a control method for an air conditioner is also provided, such as... Figure 4 As shown, the method includes:

[0109] Step 401: The air conditioner enters heating mode.

[0110] Here, the air conditioner responds to the heating mode command, enters the heating mode, controls the upper air outlet assembly to open, and obtains the indoor temperature value and the indoor heat exchanger temperature value.

[0111] Step 402: Determine if the compressor is started. If yes, proceed to step 403; otherwise, proceed to step 405.

[0112] Here, if the air conditioner responds to the heating mode command and turns on, then the air conditioner has not yet started.

[0113] Step 403: Determine whether the compressor's running time has reached the first set duration. If yes, proceed to step 406; otherwise, proceed to step 404.

[0114] Here, the air conditioner performs the anti-cold air function within a first set time period, which is 5 minutes.

[0115] Step 404: Determine whether the indoor heat exchanger temperature has reached the set temperature value T1. If yes, proceed to step 406; otherwise, proceed to step 405.

[0116] Here, the temperature value T1 is set to 30℃.

[0117] Step 405: Control the air conditioner to run at low speed.

[0118] Here, if it is determined that the indoor heat exchanger temperature is less than the set temperature T1, the air conditioner is controlled to operate at a low fan speed, which is lower than the set fan speed, and the indoor fan runs at a low speed.

[0119] Here, after step 405 is completed, step 403 is executed.

[0120] Step 406: The air conditioner operates at the set fan speed.

[0121] Step 407: Determine whether the indoor temperature value has reached the first temperature threshold. If yes, proceed to step 413; otherwise, proceed to step 408.

[0122] Step 408: Determine whether the air conditioner has exited the anti-cold air function for the second set time. If yes, proceed to step 409; otherwise, proceed to step 407.

[0123] Here, the second set duration is 3 minutes.

[0124] Step 409: Determine whether the electric auxiliary heating module is running. If yes, proceed to step 410; otherwise, proceed to step 411.

[0125] Step 410: Determine whether the indoor heat exchanger temperature has reached the third temperature threshold. If yes, proceed to step 413; otherwise, proceed to step 412.

[0126] Here, the third temperature threshold is 40℃.

[0127] Step 411: Determine whether the indoor heat exchanger temperature has reached the second temperature threshold. If yes, proceed to step 413; otherwise, proceed to step 412.

[0128] Here, the second temperature threshold is 35℃.

[0129] Step 412: Determine whether the air conditioner has been running for the fifth set time. If yes, proceed to step 413; otherwise, proceed to step 409.

[0130] Here, the fifth setting is a duration of 10 minutes.

[0131] Step 413: Control the lower air outlet assembly to open.

[0132] Here, based on the indoor temperature value, the indoor heat exchanger temperature value, or the air conditioner's operating time, the lower air outlet component is controlled to open, and the hot air generated by the air conditioner is blown out from the lower air outlet.

[0133] Step 414: Determine whether the indoor heat exchanger temperature is greater than the fourth temperature threshold. If yes, proceed to step 415; otherwise, proceed to step 416.

[0134] Here, the fourth temperature threshold is 40℃.

[0135] Step 415: Control the lower air outlet assembly to open to the maximum opening angle.

[0136] Here, after step 415 is completed, step 419 is executed.

[0137] Step 416: Determine whether the indoor heat exchanger temperature is greater than the fifth temperature threshold. If yes, proceed to step 417; otherwise, proceed to step 418.

[0138] Here, the fourth temperature threshold is 35℃.

[0139] Step 417: Control the lower air outlet assembly to open to the middle opening angle.

[0140] Step 418: Control the lower air outlet assembly to open to the minimum opening angle.

[0141] Here, the opening angle of the air outlet assembly is controlled based on the indoor heat exchanger temperature value to control the air volume of the air outlet.

[0142] Step 419: Orient the horizontal air guide assembly toward the lower air outlet.
