[0032] After a fourth preset time, if the fourth temperature difference between the air outlet temperature at the first detection position and the air outlet temperature at the second detection position is less than the sixth preset temperature and greater than or equal to the seventh preset temperature, then each indoor fan is controlled to maintain its current operating state, wherein the sixth speed and the seventh speed are obtained by successively reducing the preset speed according to the first speed; or

[0055] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0056] In the embodiments of this application, the terms "first" and "second" are used to distinguish identical or similar items with essentially the same function and effect, without limiting their order. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order, and that the terms "first" and "second" do not necessarily imply that they are different.

[0057] It should be noted that, in the embodiments of this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design scheme described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0058] As people's living standards improve, they will use the heating function of air conditioners to raise the indoor temperature when the weather is cold.

[0059] However, the electric heaters currently used in air conditioners are generally integrated PTC heaters, and the indoor fan is also integrated. During operation, it is either turned on or off. For air conditioners with large air outlets, if the temperature difference between indoors and outdoors is large, and if there is a lot of frost on the outdoor unit when the air conditioner is heating, it is easy for there to be a large temperature difference in the air coming out of different parts of the indoor air outlet, resulting in uneven indoor temperature and a poor user experience.

[0060] In view of this, this application proposes a method and device for controlling the air outlet temperature of an air conditioner. By using a segmented electric heater and a segmented indoor fan, when there is a large temperature difference in the air outlet of the air conditioner, the air outlet temperature of different parts of the air outlet can be adjusted to make the air outlet temperature of the air conditioner uniform and improve the user experience.

[0061] To facilitate understanding, the application scenarios of the embodiments of this application will be introduced first.

[0062] Figure 1 This is a schematic diagram of a scenario provided for an embodiment of this application, such as... Figure 1 As shown, the device includes an air conditioner 10, an electric heater 20, an air outlet 30, a temperature sensor 40 installed on the air outlet 30, and an indoor fan 50 located inside the air conditioner 10. The temperature sensor 40 can be used to detect the air outlet temperature of the upper and lower air outlets of the air conditioner 10.

[0063] Among them, the electric heater 20 is located inside the air conditioner 10, the air outlet 30 is the air outlet of the air conditioner 10, the electric heater 20 is a segmented electric heater, including two independently controllable electric heaters P1 and P2, the indoor fan 50 is a segmented indoor fan, including two independently controllable indoor fan units F1 and F2, and the segmented electric heater 20 and the segmented indoor fan 50 correspond to the temperature sensor.

[0064] The air conditioner 10 is electrically connected to the electric heater 20, the temperature sensor 40, and the indoor fan 50, respectively.

[0065] like Figure 1As shown, when the air conditioner 10 is working, it delivers cold or warm air from inside the air conditioner 10 through the indoor fan 50, electric heater 20 and air outlet 30 to the user's room so that the user's room temperature reaches the required temperature.

[0066] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems will be described in detail below with reference to specific embodiments. The following specific embodiments can be implemented independently or in combination with each other. The same or similar concepts or processes may not be described again in some embodiments.

[0067] Figure 2 This is a flowchart illustrating the air conditioner outlet temperature control method provided in this application embodiment. The executing entity of this application embodiment can be the air conditioner control system, and the method includes the following steps:

[0068] S201. Obtain the air outlet temperature of the air conditioner at two different detection positions (upper and lower) in heating mode.

[0069] In this embodiment of the application, the detection position refers to the position on the air guide plate at the air outlet of the air conditioner used to detect the air outlet temperature of the air conditioner.

[0070] The air outlet of the air conditioner can be divided into upper and lower sections. Temperature sensors can be installed on the baffle plate at the corresponding position of each section of the air outlet to detect the air outlet temperature of the air conditioner.

[0071] Optionally, the temperature sensors can be installed with the upper temperature sensor 5 cm from the upper edge of the air outlet, and the lower temperature sensor 5 cm from the lower edge of the air outlet. It is understood that the distance between the temperature sensor installation location and the air outlet can be set according to actual needs, and this embodiment does not impose any limitations on this.

[0072] It is understood that in this embodiment of the application, dividing the air outlet of the air conditioner into upper and lower sections is only a virtual division, not a physical division, and will not change the actual structure of the air conditioner.

[0073] After receiving a message from the user that the heating mode has been turned on, the air conditioner's control system can obtain the air outlet temperature reported by the temperature sensors at the upper and lower detection positions.

[0074] S202. Based on the air outlet temperature at two different detection locations, control the operation of the segmented electric heater and the segmented indoor fan in the air conditioner to ensure that the air outlet temperature of the air conditioner is uniform.

[0075] In this embodiment, the segmented electric heater is a PTC heater with two segments, each of which can be controlled independently and corresponds to a detection position. The segmented indoor fan has two segments, each of which can be controlled independently and corresponds to a specific electric heater.

[0076] For example, please continue to refer to Figure 1 The segmented electric heater consists of two segments, P1 and P2. Each segment can be turned on or off independently. Each segment corresponds to a temperature sensor. The segmented indoor fan consists of two segments, F1 and F2. Each indoor fan corresponds to a segment of the electric heater. That is, the electric heaters P1 and P2 and the indoor fans F1 and F2 correspond to the temperature sensors T1 and T2. In other words, each detection position corresponds to one segment of the electric heater and one segment of the indoor fan.

[0077] The air conditioner's control system, after obtaining the outlet air temperature from two different detection locations, can control the electric heaters at different locations to turn on or off, and the indoor fans to operate at different speeds, to adjust the outlet air temperature and make it uniform.

[0078] For example, the air conditioner's control system obtains two outlet air temperatures fed back by temperature sensors T1 and T2. If the outlet air temperature of T1 is lower, the air conditioner's control system can control the electric heater P1 corresponding to T1 to turn on and the speed of the corresponding indoor fan F1 to decrease, so as to adjust the outlet air temperature of the outlet where T1 is located. The electric heater P2 corresponding to T2 remains off, and the speed of the corresponding indoor fan F2 remains unchanged, so as to make the outlet air temperature of the outlets where T1 and T2 are located uniform.

[0079] It is understandable that the heating function of an air conditioner mainly relies on the compressor, and the electric heater is an auxiliary heating method.

[0080] The air conditioner outlet temperature control method provided in this application obtains the outlet air temperature at two different detection positions (upper and lower) of the air conditioner in heating mode. Based on the outlet air temperature at the two different detection positions, the method controls the operation of the segmented electric heater and segmented indoor fan in the air conditioner to ensure uniform outlet air temperature. This method divides the air conditioner's electric heater and indoor fan into two segments, with each segment corresponding to a temperature detection position. When the outlet air temperature differs at different detection positions, the corresponding electric heater and indoor fan are controlled to operate, effectively regulating the uniformity of the outlet air temperature and improving the user experience.

[0081] Figure 3 A flowchart illustrating the air conditioner outlet temperature control method provided in this application embodiment. Figure 2,exist Figure 2 Based on the illustrated embodiment, the method for controlling the air outlet temperature of an air conditioner is further described, including the following steps:

[0082] S301. If the indoor temperature is higher than the first preset temperature, when the heating mode is turned on, the segmented electric heater and segmented indoor fan will be controlled to operate according to the outdoor temperature.

[0083] In this embodiment of the application, the air conditioner control system can obtain the indoor and outdoor temperatures through a temperature sensor installed on the indoor unit of the outdoor unit of the air conditioner.

[0084] After receiving feedback from the user that the air conditioner has turned on the heating mode, the air conditioner's control system can control the operation of the segmented electric heater and the segmented indoor fan based on the outdoor and indoor temperatures fed back by the temperature sensor.

[0085] Specifically, if the indoor temperature is higher than the first preset temperature and the outdoor temperature is higher than the second preset temperature, when the heating mode is activated, the segmented electric heater is controlled to be in the off mode and the segmented indoor fan is controlled to operate at the first speed; or

[0086] If the indoor temperature is higher than the first preset temperature and the outdoor temperature is lower than the second preset temperature, when the heating mode is turned on, the segmented electric heater is controlled to be in the on mode and the segmented indoor fan is controlled to run at the second speed, wherein the first speed is greater than the second speed.

[0087] For example, when the user turns on the heating mode, if the indoor temperature Tn > 20℃ and the outdoor temperature Tw > 0℃, the segmented electric heaters P1 and P2 are controlled to be in the off mode, and the indoor fans F1 and F2 run at the first speed (1100 rpm).

[0088] If the indoor temperature Tn > 20℃ and the outdoor temperature Tw ≤ 0℃, the segmented electric heaters P1 and P2 are controlled to be in the on mode, and the indoor fans F1 and F2 run at the second speed (880 rpm).

[0089] S302. After the first preset time, obtain the air outlet temperature of the air conditioner at two different detection positions in heating mode.

[0090] In this embodiment, after the air conditioner turns on the heating mode, it mainly generates warm air through the compressor. Therefore, in order to ensure the stability of the compressor frequency increase, the outlet air temperature is detected only after a first preset time is set. For example, the first preset time can be 10 minutes, or it can be set according to actual needs. This embodiment does not limit this.

[0091] In this embodiment of the application, the specific implementation method for obtaining the air outlet temperature of the air conditioner at two different detection locations in heating mode is similar to... Figure 2 The specific implementation of S201 in the illustrated embodiment is similar and will not be described in detail here.

[0092] S303. Based on the air outlet temperatures at the first and second detection positions, obtain the first temperature difference between the air outlet temperatures at the first and second detection positions.

[0093] In this embodiment of the application, the first temperature difference refers to the difference between the outlet air temperatures at the two detection locations, which is the larger outlet air temperature minus the smaller outlet air temperature.

[0094] The air conditioner's control system can calculate the first temperature difference between the air outlet temperatures at two detection locations based on the received air outlet temperature.

[0095] S304. Based on the first temperature difference, control the operation of the segmented electric heater and segmented indoor fan of the air conditioner.

[0096] In this embodiment of the application, after obtaining the first temperature difference, the corresponding electric heater and indoor fan can be controlled to operate according to the first temperature difference so as to make the air outlet temperature of the air conditioner uniform.

[0097] Specifically, when the indoor temperature is greater than the first preset temperature and the outdoor temperature is less than the second preset temperature, if the first temperature difference is greater than the third preset temperature, the first indoor fan corresponding to the first detection position with the lower air outlet temperature is controlled to operate at the third speed, while the second indoor fan corresponding to the second detection position with the higher air outlet temperature maintains its current speed.

[0098] After a second preset time, the air outlet temperature at the first detection position and the air outlet temperature at the second detection position are obtained as a second temperature difference. If the second temperature difference is less than the third preset temperature and greater than or equal to the fourth preset temperature, the first indoor fan is controlled to operate at the fourth speed.

[0099] After a third preset time, the third temperature difference between the air outlet temperature at the first detection position and the air outlet temperature at the second detection position is obtained. If the third temperature difference is less than the fourth preset temperature but greater than or equal to the fifth preset temperature, the first indoor fan is controlled to operate at the fifth speed.

[0100] After a fourth preset time, the fourth temperature difference between the air outlet temperature at the first detection position and the air outlet temperature at the second detection position is obtained. If the fourth temperature difference is less than the fifth preset temperature but greater than or equal to the sixth preset temperature, each indoor fan is controlled to maintain its current operating state. The third, fourth, and fifth speeds are obtained by successively reducing the preset speed based on the second speed.

[0101] For example, please continue to refer to Figure 1When the indoor temperature Tn > 20℃ and the outdoor temperature Tw ≤ 0℃, the electric heaters P1 and P2 are in the on mode, and the indoor fans F1 and F2 run at the second speed (880 rpm). After the first preset time, if the first temperature difference between the temperature sensors T1 and T2 is ΔT (T1 is less than T2), and if ΔT is greater than the third preset temperature, for example, ΔT ≥ 10℃, then the indoor fan F1 corresponding to T1 is controlled to run at the third speed (100 rpm less than the second speed), and the indoor fan F2 is not adjusted for the time being.

[0102] After the second preset time, such as 5 minutes later, if the second temperature difference between T1 and T2 at this time is ΔT2, and if ΔT2 is less than the third preset temperature and greater than or equal to the fourth preset temperature, for example, 10 > ΔT2 ≥ 7℃, then control the indoor fan F1 to operate at the fourth speed (reduced by 50 revolutions based on the third speed), and the indoor fan F2 will not be adjusted for the time being.

[0103] After the third preset time, such as 5 minutes later, if the third temperature difference between T1 and T2 at this time is ΔT3, and if ΔT3 is less than the fourth preset temperature and greater than or equal to the fifth preset temperature, for example, 7 > ΔT2 ≥ 5℃, then control the indoor fan F1 to operate at the fifth speed (reduced by 30 revolutions from the fourth speed), and the indoor fan F2 will not be adjusted for the time being.

[0104] After the fourth preset time, such as 5 minutes later, if the fourth temperature difference between T1 and T2 at this time is ΔT4, and if ΔT4 is less than the fifth preset temperature and greater than or equal to the sixth preset temperature, for example, 5 > ΔT2 ≥ 3℃, the system determines that the air outlet temperature is uniform and maintains the current control operation. When the temperature difference reappears, the system will adjust again.

[0105] When the indoor temperature is higher than a first preset temperature and the outdoor temperature is higher than a second preset temperature, if the first temperature difference is greater than a third preset temperature, the first electric heater corresponding to the first detection position with the lower outlet air temperature is activated. After a second preset time, the second temperature difference between the outlet air temperature at the first and second detection positions is obtained. Based on the second temperature difference between the outlet air temperature at the first and second detection positions, the segmented electric heater and the segmented indoor fan of the air conditioner are controlled to operate. Specifically, there are two possible implementation methods:

[0106] In the first possible implementation, if the second temperature difference is less than the third preset temperature but greater than the fourth preset temperature, and the air outlet temperature at the first detection position is less than the air outlet temperature at the second detection position, then the first indoor fan is controlled to operate at the sixth speed.

[0107] After the third preset time, if the third temperature difference between the air outlet temperature at the first detection position and the air outlet temperature at the second detection position is less than the fifth preset temperature and greater than or equal to the sixth preset temperature, the first indoor fan is controlled to operate at the seventh speed.

[0108] After the fourth preset time, if the fourth temperature difference between the air outlet temperature at the first detection position and the air outlet temperature at the second detection position is less than the sixth preset temperature and greater than or equal to the seventh preset temperature, then each indoor fan is controlled to maintain its current operating state. The sixth speed and the seventh speed are obtained by successively reducing the preset speed according to the first speed.

[0109] In a second possible implementation, if the second temperature difference is less than the third preset temperature but greater than the fourth preset temperature, and the air outlet temperature at the first detection position is greater than the air outlet temperature at the second detection position, then the second electric heater is controlled to start operation.

[0110] After the third preset time, based on the air outlet temperature at the first detection position and the air outlet temperature at the second detection position, the indoor fan corresponding to the detection position with the lower air outlet temperature is controlled to operate until the air outlet temperature of the air conditioner is uniform.

[0111] For example, if the indoor temperature Tn > 20℃ and the outdoor temperature Tw > 0℃, the segmented electric heaters P1 and P2 are in the off mode, and the indoor fans F1 and F2 run at the first speed (1100 rpm). After the first preset time, if the first temperature difference ΔT is greater than the third preset temperature (e.g., ΔT ≥ 10℃), the segmented electric heater corresponding to the side with the lower outlet temperature is turned on, while the one with the higher outlet temperature remains off. For example, if T1 < T2, the electric heater P1 corresponding to T1 is turned on, while the others remain in their original state. After the second preset time, for example, after 5 minutes, if the second temperature difference is less than the third preset temperature but greater than the fourth preset temperature (e.g., 10 > ΔT2 ≥ 7℃), there are two control modes:

[0112] Mode 1: If T1 < T2, the indoor fan F1 corresponding to T1 is controlled to run at the sixth speed (reduced by 50 revolutions from the first speed), while the rest remains unchanged. After the third preset time, for example, 5 minutes, if the third temperature difference is less than the fifth preset temperature but greater than or equal to the sixth preset temperature (e.g., 5 > ΔT3 ≥ 3℃), the temperature difference tends to balance, and the indoor fan F1 corresponding to T1 is controlled to run at the seventh speed (reduced by 30 revolutions from the sixth speed), while the rest remains unchanged. After the fourth preset time, for example, 5 minutes, if the fourth temperature difference is less than the sixth preset temperature but greater than or equal to the seventh preset temperature (e.g., 3 > ΔT2 ≥ 1℃), the system determines that the outlet air temperature is uniform and maintains the current control operation. When a temperature difference occurs again, the system will adjust again.

[0113] Mode 2: If T1 > T2 at this time, the electric heater P2 corresponding to T2 is turned on. After the third preset time, for example, 5 minutes, both electric heaters are turned on. The air conditioner can be controlled according to the indoor fan control logic of indoor temperature Tn > 20℃ and outdoor temperature Tw ≤ 0℃ until the air outlet temperature of the air conditioner is uniform.

[0114] Optionally, when the air conditioner's control system receives a reading that the indoor temperature is lower than the third preset temperature, it can be assumed that the room temperature is low and requires rapid heating. Therefore, the air conditioner's outlet temperature only needs to be controlled based on the indoor temperature.

[0115] Specifically, if the indoor temperature is lower than the third preset temperature, the first electric heater and the second electric heater are controlled to operate, and the first indoor fan and the second indoor fan are controlled to operate at the first speed.

[0116] If the indoor temperature is greater than the third preset temperature but less than the eighth preset temperature, control the first electric heater and the second electric heater to operate, and control the first indoor fan and the second indoor fan to operate at the second speed.

[0117] If the indoor temperature is greater than the third preset temperature but less than the first preset temperature, control the first electric heater and the second electric heater to operate, and control the first indoor fan and the second indoor fan to operate at the eighth speed.

[0118] For example, when Tn < 10℃, the air conditioning system determines that the room temperature needs rapid heating. At this time, electric heaters P1 and P2 are both turned on, and indoor fans F1 and F2 run at the first speed (1100r / m) to achieve rapid heating. When the indoor temperature is greater than the third preset temperature but less than the eighth preset temperature, for example, 10 ≤ Tn ≤ 15℃, electric heaters P1 and P2 continue to be turned on, and indoor fans F1 and F2 run at the second speed (880r / m) to continue heating. When the indoor temperature is greater than the third preset temperature but less than the first preset temperature, for example, 15 < Tn ≤ 20℃, electric heaters P1 and P2 continue to be turned on, and indoor fans F1 and F2 run at the eighth speed (660r / m) to maintain the heating mode until the indoor temperature is greater than 20℃.

[0119] The air conditioner outlet temperature control method provided in this application obtains the outdoor and indoor temperatures of the air conditioner, and controls the operation of the segmented indoor fan and segmented electric heater of the air conditioner based on the difference between the indoor and outdoor temperatures and the outlet temperatures of the upper and lower air outlets. This can improve the uniformity of the air conditioner outlet temperature and enhance the user experience.

[0120] Optionally, this application embodiment also provides an air conditioner outlet temperature control method, applied when the user turns on the defrost mode, to reduce temperature fluctuations in the room.

[0121] When the user activates the defrost mode, the air conditioner operates in cooling mode. The air conditioner control system activates each segment of the electric heater, and the indoor unit fan runs at medium speed to neutralize the cooling capacity of the evaporator, preventing cold air from being blown out and maintaining the room temperature. When the air conditioner switches from defrost mode to heating mode, the air conditioner control system deactivates each segment of the electric heater. Because the electric heater is activated in defrost mode, the indoor evaporator temperature will not be low. After the heating mode is activated, the thermal circulation of the evaporator is accelerated, and the hot air blowing speed is increased, which can effectively maintain the stability of the room temperature.

[0122] This application also provides an air conditioner outlet temperature control device, such as... Figure 4 As shown, it includes an acquisition module 401 and a control module 402.

[0123] The acquisition module 401 is used to acquire the air outlet temperature of the air conditioner at two different detection positions, upper and lower, in heating mode.

[0124] Optionally, the control module 401 is also used to acquire the outdoor temperature, the control mode of the air conditioner, and the user's control commands.

[0125] The control module 402 is used to control the operation of the segmented electric heater and the segmented indoor fan in the air conditioner according to the air outlet temperature at two different detection locations, so as to make the air outlet temperature of the air conditioner uniform.

[0126] The segmented electric heater has two electric heater segments, and the segmented indoor fan has two indoor fan segments. Each electric heater segment corresponds to each indoor fan segment, and each electric heater segment corresponds to a detection position.
