[0055] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0056] In the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects, and do not limit their order. Those skilled in the art will understand that words such as "first" and "second" do not limit the quantity or execution order, and words such as "first" and "second" do not necessarily mean different.

[0057] It should be noted that in the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" or "for example" should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

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

[0059] However, the electric heating used in air conditioners is generally PTC heaters, which are basically integrated and are either turned on or off during operation. Due to the large temperature difference between indoor and outdoor, when the air conditioner is running in heating mode, if there is a lot of frost on the outdoor unit, it is easy for the air outlet temperature at different parts of the indoor air outlet to differ greatly, resulting in uneven indoor temperature and a poor user experience.

[0060] In view of this, the present application proposes a segmented electric heating control method and device, which uses a segmented electric heater to adjust the air outlet temperature at different parts of the air outlet 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 the present application are first introduced.

[0062] Figure 1 This is a schematic diagram of a scenario in an embodiment of the present application, such as Figure 1As shown, the air conditioner 10 includes an air conditioner 10 , an electric heater 20 , an air outlet 30 , and temperature sensors T1 , T2 , and T3 installed on the air outlet 30 . The temperature sensors are used to detect the air outlet temperatures of different parts of the air conditioner 10 .

[0063] The electric heater 20 is located inside the air conditioner 10, and the air outlet 30 is the air outlet of the air conditioner 10. The electric heater 20 is a segmented electric heater, including three independently controllable electric heaters P1, P2, and P3. The segmented electric heater corresponds to the temperature sensor.

[0064] like Figure 1 As shown, when the air conditioner 10 is working, the outdoor compressor blows cold air or warm air from the inside of the air conditioner 10 through the electric heater 20 and the air outlet 30 to the user's room, so that the user's room temperature reaches the required temperature.

[0065] The following specific embodiments are combined with the above to explain in detail the technical solution of the present application and how the technical solution of the present application solves the above technical problems. The following specific embodiments can be implemented independently or in combination with each other. For the same or similar concepts or processes, some embodiments may not be described in detail.

[0066] Figure 2 The flowchart of the electric heating control method for an air conditioner provided in the embodiment of the present application includes the following steps:

[0067] S201: Obtain air outlet temperatures of an air outlet of an air conditioner at N different detection positions in a heating mode, where N is an integer greater than or equal to 3.

[0068] In the embodiment of the present application, the detection position refers to a position on the air guide plate of the air outlet of the air conditioner for detecting the air outlet temperature of the air conditioner.

[0069] The air outlet of the air conditioner can be evenly divided into N sections according to its length. A temperature sensor is installed on the wind shield at the corresponding position of each air outlet to detect the air outlet temperature of the air conditioner.

[0070] For example, Figure 3 As shown, the air outlet of the air conditioner is divided into three sections, and a temperature sensor is installed in the middle of the air guide plate corresponding to each air outlet section. The position of each temperature sensor is a detection position.

[0071] It can be understood that in the embodiment of the present application, dividing the air outlet of the air conditioner into N sections is only a virtual division, not a physical division, and will not change the actual structure of the air conditioner.

[0072] The control system of the air conditioner, after receiving the user's request to turn on the heating mode, can obtain the corresponding air outlet temperature through temperature sensors installed at different detection positions of the air outlet.

[0073] S202 : Control the operation of each segment of the electric heater in the air conditioner according to the air outlet temperatures at N different detection positions, so as to make the air outlet temperature at the air outlet of the air conditioner uniform.

[0074] In the embodiment of the present application, the segmented electric heater is a PTC heater having N segments of electric heaters, each segment of the electric heater can be controlled individually, and each segment of the electric heater corresponds to a detection position.

[0075] For example, please refer to Figure 2 The sectional electric heater consists of three sections: P1, P2, and P3. Each section can be turned on or off independently, and each section corresponds to a temperature sensor. Specifically, heaters P1, P2, and P3 correspond to temperature sensors T1, T2, and T3, meaning each section corresponds to a detection location. To better detect the outlet air temperature, the temperature sensor can be located on the air deflector in the middle of each section.

[0076] After obtaining the air outlet temperature at N different detection positions, the control system of the air conditioner can control the electric heaters at different positions to turn on or off according to the different air outlet temperatures to adjust the air outlet temperature so that the air outlet temperature is uniform.

[0077] For example, the control system of the air conditioner obtains three air outlet temperatures fed back by temperature sensors T1, T2, and T3. If the air outlet temperature of T1 is lower, the control system of the air conditioner can control the electric heater P1 corresponding to T1 to turn on to adjust the air outlet temperature of the air outlet where T1 is located, so that the air outlet temperatures of the air outlets where T1, T2, and T3 are located are uniform.

[0078] It is understandable that the heating function of the air conditioner is mainly achieved by the compressor, and the electric heater is an auxiliary heating means.

[0079] The electric heating control method for an air conditioner provided in an embodiment of the present application obtains the outlet air temperature of the air conditioner at N different detection locations in the heating mode. Based on the outlet air temperature at these N different detection locations, the method controls the operation of each segment of the air conditioner's segmented electric heater to achieve a uniform outlet air temperature. This method divides the air conditioner's electric heater into N segments, each corresponding to a temperature detection location. When the outlet air temperature at different detection locations differs, the method controls the operation of the corresponding electric heater, effectively adjusting the outlet air temperature uniformity and improving the user experience.

[0080] Figure 4Schematic diagram of the process of the air conditioner electric heating control method provided in the embodiment of the application Figure 2 ,exist Figure 2 Based on the embodiment shown, the electric heating control method of the air conditioner is further described, which includes the following steps:

[0081] S401: If the outdoor temperature is greater than a first preset temperature, when the heating mode is turned on, the compressor of the air conditioner is controlled to work, and the sectional electric heater is in an off mode.

[0082] In the embodiment of the present application, the outdoor unit of the air conditioner is generally installed outdoors, and the outdoor temperature is the ambient temperature of the location of the outdoor unit of the air conditioner. The outdoor unit of the air conditioner is equipped with a sensor that can obtain the outdoor temperature of the air conditioner.

[0083] After receiving the user's instruction to turn on the heating mode, the control system of the air conditioner can control the operation of the segmented electric heater according to the outdoor temperature feedback received from the temperature sensor of the air conditioner outdoor unit.

[0084] If the outdoor temperature is greater than the first preset temperature, the compressor of the air conditioner is controlled to work, and the sectional electric heater is controlled to be in an off mode.

[0085] Exemplarily, the first preset temperature may be 0 degrees Celsius, or may be set according to actual needs, which is not limited in the embodiments of the present application.

[0086] S402: After a first preset time, obtain the air outlet temperature of the air outlet of the air conditioner at N different detection positions in the heating mode.

[0087] In the embodiment of the present application, after the air conditioner is turned on in heating mode, warm air is mainly generated by the compressor. Therefore, in order to ensure the stability of the compressor frequency increase, the air outlet temperature is detected only after a first preset time is set. For example, the first preset time can be 15 minutes (minutes, mins), or it can be set according to actual needs. The embodiment of the present application does not limit this.

[0088] In the embodiment of the present application, the specific implementation method of obtaining the air outlet temperature of the air conditioner in the heating mode at N different detection positions is as follows: Figure 2 The specific implementation of S201 in the illustrated embodiment is similar and will not be described in detail here.

[0089] S403 : Obtain a first temperature difference between the air outlet temperatures of any two detection positions based on the air outlet temperatures of N different detection positions.

[0090] In the embodiment of the present application, the first temperature difference refers to the difference between the air outlet temperatures of any two detection positions, and the difference is the larger air outlet temperature minus the smaller air outlet temperature.

[0091] The control system of the air conditioner can calculate a first temperature difference between the air outlet temperatures of any two detection positions based on the received air outlet temperatures.

[0092] S404: Obtain a maximum temperature difference based on a first temperature difference between air outlet temperatures at any two detection positions.

[0093] In the embodiment of the present application, since there are N detection positions, there are also multiple first temperature differences.

[0094] After obtaining the plurality of first temperature differences, the control system of the air conditioner takes the largest first temperature difference as the maximum temperature difference according to the magnitudes of the first temperature differences.

[0095] S405: Control the operation of each segment of the sectional electric heater of the air conditioner according to the maximum temperature difference.

[0096] In an embodiment of the present application, after obtaining the maximum temperature difference, the corresponding electric heater can be controlled to operate according to the maximum temperature difference to make the air outlet temperature of the air conditioner uniform, wherein each electric heater is divided into two modes: high power and low power.

[0097] Specifically, obtain the first electric heater corresponding to the first detection position where the air outlet temperature is small and the second electric heater corresponding to the second detection position where the air outlet temperature is large, and if the maximum temperature difference is greater than or equal to the second preset temperature, control the first electric heater to start high-power operation.

[0098] After the second preset time, a second 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 second temperature difference is less than the second preset temperature and greater than or equal to the third preset temperature, the first electric heater is controlled to start low-power operation.

[0099] After the third preset time, obtain the third temperature difference between the air outlet temperature of the first detection position and the air outlet temperature of the second detection position; if the third temperature difference is less than the third preset temperature and greater than or equal to the fourth preset temperature, control the first electric heater to start high-power operation and the second electric heater to start low-power operation.

[0100] After the 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 fourth preset temperature and greater than or equal to the fifth preset temperature, each electric heater is controlled to maintain the current operating state.

[0101] For example, please refer to Figure 3 If the temperature difference between temperature sensors T1 and T2 is the maximum temperature difference ΔT (T1 is less than T2), the first detection position is the position of T1, and the corresponding first electric heater is P1. The second detection position is the position of T2, and the corresponding second electric heater is P2.

[0102] If ΔT is greater than or equal to the second preset temperature, for example, 7°C, the first electric heater P1 is controlled to start high-power operation, for example, 700 watts, and the second electric heater P2 is controlled to continue to maintain the off mode; after the second preset time, for example, 5 minutes, the second temperature difference ΔT2 between T1 and T2 is obtained again. If ΔT2 is less than the second preset temperature and greater than or equal to the third preset temperature, for example, 5°C, the first electric heater P1 is controlled to start low-power operation, for example, 600 watts, and the second electric heater P2 is controlled to continue to maintain the off mode.

[0103] After the third preset time, for example, 5 minutes, the third temperature difference ΔT3 between T1 and T2 is obtained again. If ΔT3 is less than the third preset temperature and greater than or equal to the fourth preset temperature, for example, 3°C, the first electric heater P1 is controlled to start high-power operation, for example, 600 watts, and the second electric heater P2 is controlled to start low-power operation; after the fourth preset time, for example, 5 minutes, the third temperature difference ΔT4 between T1 and T2 is obtained again. If ΔT4 is less than the fourth preset temperature and greater than or equal to the fifth preset temperature, for example, 1°C, at this time, the air-conditioning control system can consider that the air outlet temperature of the air conditioner is uniform, and control each electric heater to maintain the current operating state.

[0104] Optionally, if the control system of the air conditioner receives an instruction from the user to turn on the heating mode and also receives an instruction from the user to manually turn on the electric heating mode, then when the compressor of the air conditioner is controlled to work, each section of the segmented electric heater is controlled to start low-power operation. After a first preset time, the air outlet temperature of the air conditioner at N different detection positions in the heating mode is obtained, and the operation of the segmented electric heater is controlled according to the air outlet temperature at different detection positions. The control logic is the same as the logic shown in S404-S405, and will not be repeated here.

[0105] The electric heating control method for an air conditioner provided in an embodiment of the present application is to control the compressor of the air conditioner to operate when the heating mode is on, and to control the segmented electric heater to be in the off mode when the outdoor temperature is greater than a first preset temperature. After a first preset time, the outlet air temperature of the air conditioner at N different detection positions in the heating mode is obtained. Based on the outlet air temperature at the N different detection positions, a first temperature difference between the outlet air temperatures at any two detection positions is obtained. Based on the first temperature difference between the outlet air temperatures at any two detection positions, a maximum temperature difference is obtained. Based on the maximum temperature difference, the operation of each segmented electric heater in the air conditioner is controlled. In this method, by further setting the operating conditions of the segmented electric heater according to the outdoor environment, the accuracy of adjusting the uniformity of the outlet air temperature can be improved, further enhancing the user experience.

[0106] Figure 5Schematic diagram of the process of the air conditioner electric heating control method provided in the embodiment of the application Figure 3 , Figure 4 The illustrated embodiment describes a method for controlling electric heating of an air conditioner when the outdoor environment is greater than a first preset temperature. The embodiment of the present application describes a method for controlling electric heating of an air conditioner when the outdoor environment is less than the first preset temperature, including the following steps:

[0107] S501: If the outdoor temperature is lower than a first preset temperature, when the heating mode is turned on, the compressor of the air conditioner is controlled to operate, and the segmented electric heater is turned on to operate at low power.

[0108] In the embodiment of the present application, when the outdoor temperature is lower than the first preset temperature, the air conditioning control system controls the compressor of the air conditioner to work after receiving the user's request to turn on the heating mode, and controls the segmented electric heater to start low-power operation. Figure 4 The specific implementation method of S401 in the illustrated embodiment is similar and will not be repeated here.

[0109] S502: After a first preset time, obtain the air outlet temperature of the air outlet of the air conditioner at N different detection positions in the heating mode.

[0110] The specific implementation method of S502 in the embodiment of this application is Figure 4 The specific implementation method of S402 in the illustrated embodiment is similar and will not be repeated here.

[0111] S503 : Control the operation of each segment of the sectional electric heater of the air conditioner according to the air outlet temperatures at the N different detection positions.

[0112] In the embodiment of the present application, after obtaining the air outlet temperatures at N different detection positions, the operation of the corresponding segmented electric heater can be controlled according to the different air outlet temperatures.

[0113] Specifically, if the air outlet temperatures at N different detection positions are all lower than the sixth preset temperature, each segment of the segmented electric heater is controlled to start high-power operation.

[0114] After the second preset time, if the air outlet temperature at any detection position is lower than the sixth preset temperature, the electric heater corresponding to any detection position is controlled to start high power operation, and the other electric heaters are controlled to start low power operation.

[0115] After the third preset time, if the air outlet temperatures at the N different detection positions are all greater than the sixth preset temperature, each segment of the segmented electric heater is controlled to start low-power operation.

[0116] For example, please refer to Figure 3If the air outlet temperatures detected by the temperature sensors T1, T2 and T3 are all lower than a sixth preset temperature, for example, 40°C, the segmented electric heaters P1, P2 and P3 are all controlled to operate at high power.

[0117] After the second preset time, if the air outlet temperature detected by any temperature sensor among temperature sensors T1, T2 and T3 is still lower than the sixth preset temperature, the electric heater corresponding to the temperature sensor is controlled to start high-power operation, and the other electric heaters are controlled to start low-power operation. For example, after 5 minutes, the temperature of T1 is lower than 40°C, the segmented electric heater P1 is controlled to start high-power operation, and P2 and P3 are both controlled to start low-power operation.

[0118] After the third preset time, if the air outlet temperatures detected by the temperature sensors T1 , T2 and T3 are all greater than the sixth preset temperature, the segmented electric heaters P1 , P2 and P3 are all controlled to start low-power operation.

[0119] The electric heating control method for an air conditioner provided in an embodiment of the present application controls the operation of the air conditioner's compressor and the operation of the segmented electric heater at low power when the heating mode is on, if the outdoor temperature is less than a first preset temperature. After a first preset time, the air outlet temperature of the air conditioner's air outlet at N different detection locations in the heating mode is obtained. Based on the air outlet temperature at these N different detection locations, the operation of each segmented electric heater in the air conditioner is controlled. By further setting the operating conditions of the segmented electric heater based on the outdoor environment, this method can improve the accuracy of adjusting the uniformity of the air outlet temperature, further enhancing the user experience.

[0120] Figure 2-Figure 5 The illustrated embodiment provides an air conditioner electric heating control method when the user turns on the heating mode. The embodiment of the present application also provides an air conditioner electric heating control method, which is applied when the user turns on the defrost mode to reduce temperature fluctuations in the room.

[0121] When the user turns on the defrost mode, the air conditioner runs in the cooling mode, and the air conditioner control system controls each section of the electric heater to turn on at high power, and the indoor unit fan runs at medium speed to neutralize the cold capacity of the evaporator, prevent cold air from blowing out, and maintain the room temperature; when the air conditioner changes from the defrost mode to the heating mode, the air conditioner control system controls each section of the electric heater to turn off. Since the electric heating is turned on in the defrost mode, the indoor evaporator temperature will not be low. After the heating mode is turned on, the heat cycle of the evaporator is accelerated, and the hot air blowing speed is increased, which can effectively maintain the stability of the room temperature.

[0122] The present application also provides an air conditioner electric heating control device, such as Figure 6As shown, including an acquisition module 601 and a control module 602.
